      The aim of this study is to evaluate the antileishmanial activity of selected medicinal plants from the North-West of Morocco. Plant extracts were prepared by maceration using methanol, ethanol, and n-hexane. The antileishmanial activity was evaluated against Leishmania major, Leishmania tropica, and Leishmania infantum using MTT (3-(4.5-dimethylthiazol-2yl)-2.5-diphenyltetrazolium bromide) assay. All plant extracts showed a reducing in cell promastigotes viability with variability depending on tested strains and type of extracts. The n-hexane extract showed the highest antileishmanial activity and L. infantum was the most sensitive parasite. The best growth inhibition was observed with Cistus crispus n-hexane extract against L. major (IC50 =47.29±2.25μg/mL), Arbutus unedo n-hexane extract against L. infantum (IC50 =64.05±1.44μg/mL) and Arbutus unedo n-hexane extract against L. tropica (IC50 =79.57±2.66μg/mL). Considering these results, medicinal plants from the North-West of Morocco could constitute a promoter source for antileishmanial compounds.

      Magnetic nanoparticles are a highly worthy reactant for the correlation of homogeneous inorganic and organic containing catalysts. This review deals with the very recent main advances in the development of various nano catalytic systems by the immobilization of homogeneous catalysts onto magnetic nanoparticles. Catalytic fields include the use of mainly cobalt, nickel, copper, and zinc ferrites, as well as their mixed-metal combinations with Cr, Cd, Mn and sometimes some lanthanides. The ferrite nanomaterials are obtained mainly by co-precipitation and hydrothermal methods, sometimes by the sonochemical technique, micro emulsion and flame spray synthesis route. Catalytic processes with application of ferrite nanoparticles include degradation (in particular photocatalytic), reactions of dehydrogenation, oxidation, alkylation, C–C coupling, among other processes. Ferrite nano catalysts can be easily recovered from reaction systems and reused up to several runs almost without loss of catalytic activity. Finally, we draw conclusions and present a futurity outlook for the further development of new catalytic systems which are immobilized onto magnetic nanoparticles.

      There are four major molecular mechanisms involved in the neuronal cell death are excitotoxicity, neuroinflammation, apoptosis and oxidative stress. Our objective is to explore in silico, in vitro and in vivo evaluation of neuroprotective potential of novel L-Cysteine derivatives as multi-target-directed drugs to manage neurodegenerative diseases. Fifty molecules were designed and included in the in silico analysis to evaluate their druglikeness and binding affinities towards the selected target proteins using various pharmacokinetic and docking software. Based on in silico results and synthetic feasibility, nine compounds were selected for synthesis, spectral analysis, in vitro and in vivo neuroprotective evaluation on neuroblastoma cell line and aluminium induced neurotoxicity in rats. Selected compounds gained best docking score and obey Lipinski’s rule of five. In vitro results showed that the compound 1a and 1b significantly increased the percentage viability (81.03 ±4.78 and 76.1 ±1.99) of human neuroblastoma cells at concentration of 100 µg. Mean retention latencies and oxidative stress were significantly decreased (P < 0.01) in test 2 and test 3 groups on day 21 and 42 when compared to disease control. In vitro study revealed the significant neuroprotective effect of compound 1a and 1b against glutamate induced neurotoxicity in SH SY-5Y cell line. The retention latency and biochemical parameters suggest that 1a has neuroprotective effect in aluminium induced Alzheimer’s disease model in rats.

      The restoration of endodontically treated teeth is one of the main challenges in restorative dentistry since the weakened tooth structure is more prone to biomechanical failures due to significant tooth loss. The aim of this paper is to computational analysis of prepared crowned tooth in order to differentiate the possibility of using porcelain material for typical clinical condition and masticatory load by using the three-dimensional finite element method (3D FEM). In order to have an accurate geometry of tooth model, a coordinate measuring machine (CMM) is proposed to scan the tooth. The obtained scanned contours exported to ABAQUS FE package for computational stress analysis. The prosthodontics crown FEM has been created and put on simulated chewing stresses. The model is composed of four different materials, namely; prepared tooth, luting cement, substructure (IPS Empress Core), and Ingot (IPS Empress Layer). The generated FEM run and the stress distributions of the crowned tooth is thoroughly investigated. The developed model is extremely useful for indicating tooth biomechanics and has the tendency to deliver a better understanding to designers in the biomedical engineering field and dentistry.

      Eel fish (Monopterus albus) is a functional food that has shown remarkable effects on a range of diseases, which include inflammatory diseases, type 2 diabetes and cancer. This study emphasized on the use of microwave-assisted extraction (MAE) technique in studying the effects of three MAE parameters (irradiation time, microwave temperature and microwave power) to obtain extract from eel fish using ethanol as the extracting solvent. The free fatty acid (FFA), acid value, fatty acid contents, and functional groups in the extract were also examined. More so, the maximum extraction yield of 16.13% w/w was obtained at a microwave power of 800 W, FFA and acid value of 1.35 and 2.69 mg KOH/g, respectively confirmed good quality of the obtained extract. In addition, the major fatty acid contents in the extract using gas chromatography-mass spectrometry (GC-MS) analysis were arachidonic acid, linolenic acid, myristic acid, oleic acid, palmitic acid, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). Consequently, the Fourier transform infrared spectrometry (FTIR) analysis confirmed the presence of different functional groups in the extract. Therefore, this study divulged that MAE is an efficient and reliable technique for extracting high yields of fatty acids from M. albus fish with a notable potential for industrial applications.

      The present study reports the enzyme 1-aminocyclopropane-1-carboxylate deaminase (ACCD) from Trichoderma strains TSK8 and SKS1 enhance the growth mangroves (Rhizophora) evidenced by primary enzyme quantification followed by greenhouse experiments. The results indicated that ACCD enzyme activity about 20% higher in strain SKS1 than that of strain TSK8. In the greenhouse study, we analyzed the effect of Trichoderma treatment on physiological and biochemical characteristics of mangrove seedlings. The results demonstrated that SKS1 significantly enhanced the growth of mangroves (Rhizophora apiculata and Rhizophora mucronata) as compared to control (untreated). The strain TSK8 and SKS1 increased the plant total biomass by 43.26% and 41.23% respectively in R. mucronata. Particularly, SKS1 showed the 70.8% biomass increase in R. apiculata. The growth was investigated with and without the addition of soluble phosphate were investigated. Thusly, the fungal strains SKS1 and TSK8 derived ACCD has potency on the mangroves growth enhancement. Thus present work provided the platform for the development of Trichoderma sp. based biofertilizer for a promising approach for the restoration of aquatic plants.

      Bio-informatics research fields are progressively growing enriched with the incremental use of R tools. Anxiety Disorders can be defined as one of the most common mental disorders. They are tangible psychiatric disorders or a group of mental illnesses thought to be caused by either genetic vulnerability or environmental susceptibility factors. Several studies have revealed that anxiety is associated with an increased risk of Angina, Asthma, Diabetes, Heart Attack and High Blood Pressure. Thus, these five anxiety disorders must have some genetic association among them. Finding the genetic relationship among the above diseases will help to understand the gene linkage and connection association among them which leads to the way to common drug design. Here, after investigating the genetic association of Angina, Asthma, Diabetes, Heart Attack and High Blood Pressure a Regulatory Interaction Network is designed using R. The investigated diseases genes are collected, preprocessed, processed, mined and optimized using R. This research aimed to create a new dimension in the field of drug design.

      Morphology of the face depends on many factors, such as sex, ethnicity, race, climate, nutrition, genetic constitution and socio-economic status. In the developed countries, there is well established database on facial anthropometry and for the purpose of identification. In Ghana however, there is very little documented information on cephalometric indices for biometric and forensic purposes. This study therefore, aimed at establishing baseline data to assess the relationship between sex using upper, lower and total cephalometric indices. One hundred participants made up of sixty males and forty females from KNUST were recruited for the study. Linear facial anthropometry were taken using calibrated Shahe digital calipers whiles participants sat with head in natural position. The facial anthropometric measurements were generally higher in males than in females. Upper facial height, facial width, nasal width, biocular diameter, lower facial height, lip length and total facial height were statistically significant and (p < 0.05). The present study shows the existence of statistically significant sexual dimorphism in the study population using cephalo-facial dimensions.

      Despite response surface methodology (RSM) has been the most preferred statistical tool for optimizing extraction processes, artificial neural network (ANN) has been one of the most effective tools used for optimization and empirical modelling since the last two decades, most especially for non-linear equations. Thus, this study was carried out to compare the performance of RSM and ANN in optimizing the extraction yield and antioxidant capability of extract from Vernonia cinerea leaves using microwave-assisted extraction (MAE) techniques. The responses (extraction yield and antioxidant capabilities) were modelled and optimized as functions of four independent MAE parameters (irradiation time, microwave power level, ethanol concentration, and feed-to-solvent ratio) using RSM and ANN. The coefficient of determination (R2), root mean square error (RMSE) and absolute average deviation (AAD) were employed to compare the performance of both modelling tools. ANN model has a higher predictive potential compared to RSM model with higher correlation coefficients of 0.9912, 0.9928 and 0.9944 for extraction yield, DPPH and ABTS scavenging activities, respectively. Thus, ANN model could be a better alternative in data fitting for the MAE of antioxidants from Vernonia cinerea leaves.

      In this article, flow formation of fully developed mixed convection flow of an incompressible, viscous and electrically conducting fluid in vertical permeable micro-channel in presence of induced magnetic field is analyzed. The effects of velocity slip and temperature jump are taken into account. The influence of induced magnetic field arising due to the motion of an electrically conducting fluid in the presence of transverse magnetic field is taken into consideration. The governing equations of the motion are a set of simultaneous ordinary differential equations and their exact solutions in dimensionless form have been obtained for the velocity field, the induced magnetic field and the temperature field. The expressions for the induced current density and skin friction have also been obtained. Numerical procedures are examined for various active parameters namely: suction/injection, rarefaction, fluid wall interaction, mixed convection, Hartmann number and the magnetic Prandtl number. Results revealed that, increase in Hartmann number and magnetic Prandtl number causes a pronounced reduction in skin friction.

      Nifedipine has poor aqueous solubility which limits its oral absorption as unit formulation. This limitation was acted through multiparticulate pulsatile systems for the treatment of angina pectoris. Initially, solid dispersions of nifedipine (NF) using sodium starch glycolate (SSG) and guar gum (GG) in 1:1 and 1:2 ratios were processed by kneading technique. Solution layering technique was employed to coat the solid dispersions on non-pareil sugar spheres (∼450 µm) to obtain immediate (NMP 1 and 2) and controlled release pellets (NMP-3 and 4). Controlled release pellets were further coated with Eudragit L100 and RS100 to achieve pulsatile pellets (NMPP-1 to 5). Pellets were subjected to saturation solubility, FTIR, DSC, micromeritics, SEM, drug content, drug release, pharmacokinetic and stability studies. By means of solid dispersions, solubility of NF was increased by 130-folds due to encompassing ordered interparticle mixing of NF and carriers. Significant interactions between NF and carriers were not demonstrated in FTIR spectra as well as in DSC thermograms. Fluidization process again proved its supremacy in producing defined spherical shaped pellets with desired micromeritics. Solution layering process resulted with high drug content (81–94.2%) and maximum drug was released by end of 12 h with 6 h lag phase. Suitable pharmacokinetic parameters were moderated by immediate (NMP) and pulsatile pellets (NMPP) as Cmax of 820 ng/mL for NMP-2 and 360.8 ng/mL for NMPP-5 at 5 and 16 h respectively. Increased pharmacokinetics and bioavailability were the result of linear increase in solubility of NF with solid dispersions. The pulsatile formulations were physicochemically intact over a period of time. Thus, multiparticulate systems of NF had demonstrated their applicability in chronotherapy of circadian based ailments.

      Chemometric descriptors were used to analyze quantitatively the anticonvulsant activity of ninety propanamide derivatives. Molecular geometries of the data set were optimized with B3LYP/6-31G∗∗ quantum mechanical method and chemometric descriptors were calculated from the optimized structure. Linear QSAR models were developed using genetic function algorithm. Predictive capabilities of the models were evaluated using various internal and external validation techniques. The best three models proposed were octa-parametric equation with good statistical quality: R2 (0.898–0.918); Q2 (0.865–0.893); R2 pred (0.746–0.772) and F (66.657–88.036). 2-acetamido-N-benzyl-2-(5-methylfuran-2-yl) acetamide a member of the data set was chosen as scaffold for in silico design. Using the information afforded by the models, several attempts were made to optimize the scaffold by introducing various modifications. Potential derivatives with higher predicted activity values than the template were identified and a detailed analysis on the models applicability domain defined the designed compounds, whose estimations can be accepted with confidence. Some of the designed compounds docked with γ-aminobutyrate aminotransferase (PBD: 1OHV) (target) showed better binding affinity for the target when compare with 4-aminohex-5-enoic acid (vigabatrin) (a known inhibitor of the target).

      The present work was aimed to study the morphological and histological features of goose pancreas and to investigate the ultrastructure of pancreatic acini. This study was conducted on the pancreas of ten healthy mature birds of goose. The pancreas was excised from the duodenum rapidly after slaughter of the birds. The specimens were fixed in 10% buffered neutral formalin then processed for light and electron microscopic study. The macroscopic observations revealed that goose pancreas was located in the right side of the abdomen between the ascending and descending loops of duodenum. It was formed from dorsal, splenic, ventral and third lobes. The histological observations revealed that the pancreas was formed of lobules of serous acini. The secretory acinus unit was appearing as a single spherical mass composed of many serous cells surrounding narrow lumen. The pyramidal acinar cells appeared bizonal structure; the basal basophilic cytoplasm and apical acidophilic cytoplasm. Centroacinar cells were slightly smaller cells that appeared brighter than the acinar cells and were located in the center of the lumen of the acinus. The duct system was well developed began with the centroacinar cells. Underneath electron microscope, the acinar cells have been two kinds, the electron dense acinar cells with electron dense cytoplasm and heterochromatic nuclei and the electron lucent acinar cells, which characterized by means of electron lucent cytoplasm, and their nuclei had considerable euchromatin, abundant endoplasmic reticulum, mitochondria and numerous zymogen granules, and considered active cells.

      A total of 1242 out of 1484 Trichogaster fasciatus fish were found to be infected with metacercarial stage of Clinostomum complanatum where 14,258 parasites were recorded mainly from the peritoneal cavity, gills and viscera during five years of study period. The seasonal variations in prevalence, intensity and abundance of the parasitic infection were assessed. The maximum and minimum values of prevalence of metacercarial infection of C. complanatum in the fish were 92.40% and 70.40% during summer and winter respectively. Similarly, intensity and abundance of the parasite were maximum during summer as compared to winter and rainy seasons. The high prevalence of infection of the parasite during summer may be because of the time of emergence of cercariae in high temperature from snail vector and the environment.

      The goal of the present work was to study the protective role of the essential oil of Elettaria cardamomum (cardamom) against diethylnitrosamine (DENA)-induced oxidative stress in the kidney and brain of rats in comparison with geraniol, a pure compound as one of the main components of cardamom essential oil. Geraniol or cardamom essential oil was orally administered every day (100 and 200 mg/kg) for 1 week before DENA administration and continuously administered for 26 weeks. The levels of brain and kidney ornithine decarboxylase (ODC), brain acetylcholinesterase (AChE) and renal markers such as urea and creatinine were elevated after DENA administration. However, cardamom and geraniol administration decreased kidney and brain oxidative stress and lowered the activity of ODC in brain and kidney and the activity of AChE in brain. Cardamom or geraniol had significantly reduced the level of lipid peroxidation to almost half the value in DENA group and enhanced glutathione level by double its values in brain and kidney compared to glutathione levels in DENA treated-rats. In addition, geraniol or oil of cardamom improved the activities of the antioxidant markers; catalase, superoxide dismutase, glutathione peroxidase, glutathione reductase, and glutathione-S transferase in the brain and kidneys of DENA-treated rats. The results support the chemopreventive, antioxidant, neuroprotective and anticancer effects of the essential oil of cardamom, which are mediated through its inhibition of ODC and AChE activities and activation of antioxidant markers.

      In this study, the phytoplankton biomass and species composition in El-Quanater El-Khayria (River Nile, Egypt) was analyzed at four sampling sites on a program of a seasonally sampling and supported by measurements of different water variables as well as biomass production of most common aquatic macrophytes. The major species of aquatic macrophytes were two submerged species (Ceratophyllum demersum and Ceratophyllum submersum), two emergent (Polygonum tomentosum and spontaneum), and one free floating aquatic macrophyte (Eichhornia crassipes). Considerable seasonal variations in water quality as well as macrophytes biomass were found in the studied areas, which result in a variation of phytoplankton flora. A total of 235 phytoplankton species belonging to 7 classes was recorded, with higher numbers in autumn and winter compared to spring and summer. The maximum number of phytoplankton (7238 × 104 L−1 cells) was recorded in winter, however, the lowest one (96 × 104 L−1 cells) recorded in spring. Chlorophyceae was the dominant group, forming 56.96% of the total phytoplankton biomass followed by Bacillariophyceae (34.82%), Cyanophyceae (7.99%), Cryptophyceae (0.10%), Dinophyceae (0.096%), Chrysophyceae (0.03%) and Euglenophyceae (0.02%). Chlorophyll a values ranged from 9.77 µg L−1 to 69.81 µg L−1, with a considerable seasonal and spatial variation. All phytoplankton classes as well as, chlorophyll a was negatively correlated with all aquatic macrophytes species except for C. submersum which correlated positively with chlorophyll a and Cyanophyceae. In addition, it was positively correlated with pH, conductivity and dissolved oxygen.

      Present study was carried out to develop a potent mutant for enhancing secondary metabolite production from Monascus sanguineus. Ultraviolet (UV) treatment as physical and Ethyl methane sulphonate (EMS) as chemical mutagen was used to cultivate the mutants. All obtained mutants were screened for growth and pigment yield on three different synthetic media namely; potato dextrose agar (PDA), malt glucose peptone agar (MGPA) and Czapek Dox yeast extract Agar (CDYA). MGPA media was found suitable for pigment yield whereas appreciable growth was observed with CDYA. Highest pigment yield was obtained for mutants developed at EMS concentration of 0.6 μg/μL (EMS-3) and UV exposed for seven minutes (UV-4). Exposure to UV for 11 min suppressed the pigment production. However this exposed strain (albino) was found to be an efficient producer of lovastatin with no traces of citrinin alike parental strain. Both EMS-3 and UV-4 mutants had synthesized negligible amount of citrinin, well below regulatory toxic levels. Significant variation was also noticed on the spore morphology of tested strains. Aleuroconidia was observed with albino strain whereas clestothesium along with pigmented ascospores were noticed with UV-4 and EMS-3 mutants. In a nutshell, these strains can be endorsed as nontoxic and safe for human consumption.

      The main object of the present study is to isolate and characterize the actinomycetes from Koringa mangrove soil samples near Kakinada, Andhra Pradesh, India. Isolated actinomycetes were assessed for antagonistic activity against various bacteria and fungi. The potent strain KMFA-1 having activity against dermatophytes Candida albicans and Pectinotrichum llanense was characterized. Based on physiological, morphological characteristics and 16s rRNA gene sequencing the isolated strain was identified as Streptomyces hydrogenans. Extraction was done with different solvents and the activity was evaluated for each solvent extract. The antibiotic that is responsible for activity is found to be highly water soluble. The bioactive metabolite present in crude supernatant was found to be stable at 80 °C for 1 h, 90% activity was retained after boiling at 100 °C for 1 h, but 53.4% activity was reduced after autoclaving (at 121 °C for 15 min). The activity was not lost when the crude supernatant was subjected to wide range of pH (2–10). Furthermore, analytical techniques must be employed to isolate the molecule of interest. The result of present study revealed that the Streptomyces hydrogenans produced an interesting antifungal metabolite.

      Visfatin (Nicotinamide phosphoribosyltransferase) is an adipokine implicated in mediating insulin resistance and exhibiting insulin mimetic effect and therefore represents a druggable target for diabetes therapy. About 3,844 peroxisome proliferator activated receptor gamma (PPARγ) agonists documented in Chembl database were docked with PPARγ and those with binding energy of >−9 kcal/mol having experimental EC50 of 0.1 to 1 nM were selected. The candidate compounds (27) were thereafter docked with visfatin (PDB ID: 4WQ6) using AutodockVina out of which eight compounds that ranked highest in binding energy (when compared with the co-crystallized ligand of visfatin: 3TQ) were selected. Compound 25 exhibited favorable ligand-protein molecular interaction and respected Lipinski’s rule of five and interestingly from the absorption, distribution, metabolism and excretion (ADME)-Toxicity analysis the compound have enhanced pharmacological properties than the current ligand of visfatin.

      Pumpkin seeds (Cucurbita pepo) and Pomegranate peel (Punica granatum) have anthelmintic properties. The aim of this study was to compare the anthelmintic efficacy of pumpkin seeds ethanolic extract and pomegranate peel aqueous extract against Ascaridia galli in vitro and in vivo in Baladi chicks. On adult worms, the extracts of the two herbs were compared in vitro at concentrations of 25, 50, and 75 mg/ml with fenbendazole at a concentration of 5 mg/ml. Chicks were infected with Ascaridia galli eggs containing second stage larva and treated with 2000 mg/kg of each of the extracts compared with 100 mg/kg fenbendazole. In vitro, all concentrations of pumpkin seed extract and the concentration of 75 mg/ml pomegranate peel extract exhibited a nearly similar effect to fenbendazole. In vivo, the mortality rate of the worms extracted from the 2000 mg/kg pumpkin seeds extract-treated chicken was non-significantly different from that of fenbendazole for 48 h. While pomegranate peels extract exhibited a lower lethal effect than fenbendazole. The anthelmintic efficacy was dependent on time and concentration. The study presented the anthelmintic efficacy of the pumpkin seeds and pomegranate peel extracts on Ascaridia galli. Pumpkin seed extract was more effective than pomegranate peel extract. Future studies to determine the optimal dose to maximize their effectiveness especially for pumpkin seeds as anthelmintic therapeutic are required.

      The main objective of this study is to investigate the still unexplored River Nile habitat since it was found little information on the chemistry and biology of the River Nile derived microorganisms. Therefor it was claimed to isolate a number of microorganisms, identify them and test their antimicrobial activities. On the other hand isolation of at least one bioactive metabolite from isolated fungus grown under static condition. A number of microorganisms has been isolated using three different media; TSA (Trypton Soya Agar), SDA (Sabroud Dextrose Agar) and ISP4 (International Streptomyces Project 4), their antimicrobial activities were studied using two agar diffusion methods; cup and modified agar disc methods. Chromatographic techniques were used for isolation of one compound which also tested for its antimicrobial and cytotoxic activity. Thirty-four versatile isolates were recovered, related to Gram positive bacteria, Gram negative bacteria, fungi and actinomycetes. The antimicrobial screening showed varying activities against tested strains in both methods. Isolation of Di-(2-ethylhexyl) Phthalate (DEHP) compound from fungus Aspergillus awamori had been succeeded, it is the first report for its isolation from the titled fungus, DEHP exhibited activity against Candida albicans fungus and the Gram positive bacteria Sarcina lutea, also DEHP showed cytotoxic activity against some carcinoma cell lines. It can be concluded that the River Nile could be a tremendous resource for production of bioactive metabolites.

      The intracellular accumulation of gentamicin acts on mitochondria directly (by increasing oxidative stress) and indirectly (by increasing the proapoptotic BAX gene expression levels) and thus activates intrinsic pathway of apoptosis. This study intended to investigate the probable prophylactic effect of wheat germ as a nephro-protective agent in relation to vitamin E as a well-known natural antioxidant on a nephrotoxic model induced by gentamicin. Forty male Sprague Dawley rats were divided randomly into four groups; of 10 rats each: control group, gentamicin group (120 mg/kg/day i.p. for 15 days), vitamin E group (200 mg/kg orally for 45 days) and wheat germ group (20% of the diet for 45 days). Gentamicin injection was started on the 30th day for both groups (3) and (4). It was noticed that wheat germ significantly decreased BAX/BCL-2 ratio. The significant decrement in MDA level and the significant increment in total antioxidant capacity (TAC) level and catalase (CAT) activity of wheat germ treated rats reflecting its antioxidant activity. Additionally, the wheat germ succeeded in improvement of the kidney function of rats of this group which was manifested by amelioration of deteriorated serum creatinine, urea, sodium and potassium levels. In conclusion, the efficacy of wheat germ as anti-apoptotic and antioxidant was higher than that of vitamin E and it effectively protected against the direct and indirect toxic effects of gentamicin on kidney through regulation of BAX-BCL-2 gene expressions and further inhibition of mitochondrial cytochrome c translocation into cytosol.

      The present study declares the relationship between the cause of death and postmortem biochemical marker alterations in CSF, serum and plasma. In addition, immunohistochemical and microarchitecture examination of brain tissue of White New Zealand rabbits at different PMI after traumatized death. Thirty adult male White New Zealand rabbits were divided into two main equal groups; the first was physically killed by cervical dislocation and the second through head trauma. Each group was subdivided into three PMIs (zero, 6, and 12hrs PM). CSF was used to detect the levels of K+, Na+, Ca++, albumin While, lactic acid, hypoxanthine, ammonia and uric acid concentrations were measured in plasma. Estimation of HMGB1, IL-1β and TNF-α were assessed in serum. In addition to immunohistochemical observations of Bcl-2 and P53 apoptotic proteins in brain tissue. The results revealed that some of the examined parameters as K+, Na+, albumin, ammonia, hypoxanthine and HMGB1 had the potential role in estimation of PMI at examined time periods in physical and traumatized death. Traumatic death induced severe cerebral hemorrhages and necrosis of cerebral parenchyma than physical death. Immunohistochemical results of P53 and Bcl-2 in brain tissue declared focal positive reactions of some neurons, astrocytes and microglia in different degrees with time since death. It was concluded that biochemical analysis of some body fluids, tissue pathological changes and apoptotic markers are applicable tools for assessing accurate PMI after traumatic brain injury and could have a crucial role in legal medicine

      Amiodarone was an orally effective antiarrhythmic drug widely used throughout the world, had long-term administration side effects such as hepatotoxicity. The actions of two antioxidants; grape seed and ginkgo biloba on the extent of tissue damage in amiodarone-induced hepatotoxicity were elucidated in this study. We equally divided thirty six albino rats into six groups given doses by gastric tube daily for 8 weeks as follow; the 1st group (G1) served as an untreated control group under the same laboratory conditions and was given distilled water, the 2nd group (G2) grape seed-treated group that received (100 mg/kg/day), the 3rd group (G3) ginkgo biloba-treated group that received (100 mg/kg/day), the 4th group (G4) amiodarone-treated group that received (40 mg/kg/day), the 5th group (G5) received amiodarone parallel with grape seed at the same time and the 6th group (G6) received amiodarone parallel with ginkgo biloba at the same time. The current histological study revealed that amiodarone caused marked change in the liver including degeneration, proliferation of bile duct, inflammatory cells infiltration and fatty changes of hepatocytes in addition to deposition of collagen fibers in the hepatic tissue moreover, ultra-structural observations in the liver including vacuolation, fibrosis and pyknotic nuclei. In addition, histochemical study revealed depletion of glycogen and comet assay revealed marked of DNA damage. Treatment with the two used antioxidants reduced the extent of liver damage induced by amiodarone as indicated by decreased Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) activities. These antioxidants ameliorated the histopathological, histochemical and ultrastructure alternations of the liver tissue. In conclusion, grape seed was markedly effective than ginkgo biloba in protecting rats against amiodarone.

      Gossypium spp. belong to a class of botanicals with global therapeutic applications against a number of disorders including ulcers. This study evaluated the membrane stabilization and detoxification potential of aqueous leaf extract of Gossypium barbadense L. (Malvaceae) in indomethacin-induced oxidative gastric ulceration in Wistar rats. The ulcerated rats were orally pretreated with the extract and esomeprazole for 4weeks. Gastric function and antioxidative parameters were thereafter evaluated. The indomethacin-mediated significant elevations in the ulcer index, gastric volume, pepsin activity and mucosal level of malondialdehyde were dosedependently attenuated in the extract-treated animals. The extract also significantly modulated and improved the pH, mucin content, glutathione (reduced) as well as gastric activities of superoxide dismutase and catalase in the ulcerated rats. These improvements may be ascribed to the antioxidant and membrane stabilization activities of the extract which are attributable to its active metabolites as revealed by the analytical chromatogram. The observed effects compared favorably with that of esomeprazole and are suggestive of the capability of the extract to prevent mucosal damage and preserve gastric functions as evidently supported by the macroscopical appearance of the stomachs and the % ulcer inhibitory values. Conclusively, the overall data from the present findings suggest that the aqueous leaf extract of G. barbadense could prevent indomethacin-mediated oxidative gastric ulceration via fortification of antioxidant defense mechanisms.

      Malignant melanoma is one of the most lethal skin cancer due its high capability for metastasis. Its incidence has shown a dramatic increase over the past few decades. Primary oral melanoma is uncommon neoplasm, it can be present at any site in the oral cavity, with more frequent occurrence at the hard palate and maxillary alveolar mucosa. The prognosis of primary oral melanoma is extremely poor especially in advanced stage. The case presented here provides an example of how dental clinician have a major role in identifying malignant melanoma in any suspicious proliferating interdentally originated mass with partially pigmented area.

      The current investigation was aimed to assess anti-anaphylactic, mast cell stabilizing and anti-asthmatic activity of methanol and aqueous extract of Euphorbia hirta (Euphorbiaceae) on experimental animals. Anaphylaxis was induced by administration of horse serum and triple antigen vaccine subcutaneously in albino Wistar rats. Extracts of E. hirta (EH) were administered to the rats in dose of 250 and 500 mg/kg b.w. orally for 14 days. At the end of treatment, asthma score was measured and various blood parameters like differential count (DC), total WBC count and IgE were estimated. Interleukin (IL)-4, IL-5 and tumour necrosis factor (TNF)-α were measured by ELISA commercial kit from Broncho alveolar lavage fluid (BALF). Histopathological changes of lungs were observed. Anti-asthmatic activity of extracts of EH was also studied on histamine-induced bronchospasm in guinea pigs. In vitro mast cell stabilizing activity of extracts was evaluated on compound 48/80 challenged rat intestinal mesenteric mast cells. The treatment with extracts of EH produced significant decrease in asthma score and they also brought to normalcy the increased total WBC, DC counts, serum IgE, TNF-α, IL-4 and IL-5 in BALF. The histopathological study further supported the protective effect of EH extracts. The pre-treatment with extracts of EH displayed significant reduction in degranulation of mesenteric mast cell numbers. The treatment with extracts of EH significantly increased in time of pre-convulsive dyspnoea (PCD). Thus, these findings concluded that E. hirta could be effectively used in the treatment of anaphylaxis and asthma.

      Gum acacia, known as Gum Arabic in Oman is widely grown all over the tropical countries including Gulf region. The antimicrobial and cytotoxic activities of different polarity organic extracts of Omani and Sudanese Gum acacia latex has been investigated in this study using maceration method. Both Omani and Sudanese Gum acacia latex samples were used to prepare different fractions using various organic solvents. The antimicrobial activity of different organic extracts was determined through disc diffusion method against clinically isolated bacterial strains. The isolated pathogenic bacterial strain are Gram (+) Staphylococcus aureus (S. aureus, Code no. 659), Gram (-) Escherichia coli (E. coli, Code no. 846), Gram (-) Escherichia coli (E. coli, Code no. 683) and Gram (-) Klebsiella pneumoniae (Code no. 684). The antibiotic levofloxacin and dimethyl sulphoxide (DMSO) were used as positive and negative controls. The cytotoxic activity of the above mentioned organic extracts was determined by brine shrimp lethality method (BSL). Both latex samples of various polarity organic extracts at different concentrations showed antimicrobial activity against the isolated human bacterial strains with an inhibition range of 0-15 mm. However, both latex samples did not reveal a significant cytotoxic activity at any concentration. In conclusion, the organic extracts from both types of Gum acacia (Omani and Sudanese) represent a good source of natural antibiotic for the treatment of various infectious diseases.

      In the present investigation, an antihyperlipidemic activity of Cladophora koeiei ethanol extract against six pathogenic bacteria was conducted. Also, we evaluate the activity of the alga extract against hyperlipedemia in the administrated albino rates through measuring the blood lipid profiles [triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL-C), high-density lipoprotein cholesterol (HDL-C), cholesterol] and induced hepatic damage by measuring the contents of creatinine, total proteins, blood urea nitrogen (BUN), albumin and globulin and diagnostic marker enzymes such as aspartate aminotransaminase (AST) and alanine aminotransaminase (ALT). Alga extract proved efficient activity against the tested bacteria ranged between medium and high suppression action. Results revealed also, the efficiency of C. koeiei extract in the decreasing the triglycerides (TG), total cholesterol (TC), low-density lipoproteins (LDL-C), blood urea nitrogen (BUN) and creatinine caused by alcohol. However, the treatment by alga extract exhibits high-density of lipoproteins (HDL-C) (beneficial), total protein, albumin, and globulins. Also, the algal treatments masking the lethal effects caused by harmful alcohol from raising the rate of enzymes ALT, AST, which returned to the normal state in the groups treated with alga extract. Our findings provide the evidence that new natural antioxidant substances can be present in the C. koeiei extract and hence this alga proves to be effective as a source for therapeutic agents.

      Heat transfer devices have been used for conversion and recovery of heat in many industrial and domestic applications. Over five decades, there has been concerted effort to develop design of heat exchanger that can result in reduction in energy requirement as well as material and other cost saving. Heat transfer enhancement techniques generally reduce the thermal resistance either by increasing the effective heat transfer surface area or by generating turbulence. Sometimes these changes are accompanied by an increase in the required pumping power which results in higher cost. The effectiveness of a heat transfer enhancement technique is evaluated by the Thermal Performance Factor which is a ratio of the change in the heat transfer rate to change in friction factor. Various types of inserts are used in many heat transfer enhancement devices. Geometrical parameters of the insert namely the width, length, twist ratio, twist direction, etc. affect the heat transfer. For example counter double twisted tape insert has TPF of more than 2 and combined twisted tape insert with wire coil can give a better performance in both laminar and turbulent flow compared to twisted tape and wire coil alone. In many cases, roughness gives better performance than the twisted tape as seen in case of flow with large Prandtl Number. The artificial roughness can be developed by employing a corrugated surface which improves the heat transfer characteristics by breaking and destabilizing the thermal boundary layer. This paper provides a comprehensive review of passive heat transfer devices and their relative merits for wide variety of industrial applications.

      The study is undertaken to determine the adulticidal efficacy and repellent activity of different solvent extracts of Ocimum caninum, Ocimum gratissimum, Chromolaena odorata and Datura stramonium against adult Anopheles gambiae. The extracts showed adulticidal activity at LC50 (0.82-4.58mg/l) and LC90 (2.38-8.33mg/l). The highest mortality was observed in Ocimum gratissimum and Datura stramonium with the LC50 and LC90 values of 2.35mg/l, 4.75ml/l and 0.82mg/l, 2.38mg/l respectively. Meanwhile, the lowest adulticidal activity was recorded in Chromolaena odorata with the lowest LC50 (4.52mg/l) and LC90 (8.32mg/l). The repellent efficacy was determined against the mosquitoes at five concentrations viz 1.0, 2.0, 3.0, 4.0 and 5.0 mg/l under laboratory condition (28±2°C, 75±5% RH, 12L: 12D photoperiod). The results showed complete protections of 90mins for Ocimum caninum, 120mins for Ocimum gratissimum, 30mins for Chromolaena odorata and 120mins for Datura stramonium at 5mg/l of the extracts respectively. It was observed that D. stramonium and O. gratissimum provided highest protection (120mins) against Anopheles gambiae while the least protection (30s) was observed in Chromolaena odorata at 5mg/l. The results of the study showed that all the crude extracts with the exception of Chromolaena odorata were potential botanicals for confirming protection on the exposed parts of human body against Anopheles gambiae for at least 90mins and as such can be included in integrated vector management to reduce malaria infection in endemic areas.

      Polymorphisms of the renin-angiotensin system genes influence the pathogenesis of atherosclerosis and are connected with heart diseases. We explore the potential associations of ACE (I/D) and AGT (M235T) gene polymorphisms with coronary artery disease (CAD). A total of one hundred and twenty Egyptian patients (Sixty with CAD and sixty without CAD) and fifty healthy control subjects were included in the study. Genotyping of ACE (I/D) and AGT (M235T) were analyzed by the polymerase chain reaction (PCR) technique. Serum lipid profiles (total cholesterol, triglyceride, HDL-C) were measured by the enzymatic colorimetric method. Our data showed that the ACE D allele frequency (P<0.0001; odds ratio [OR] =2.538, 95% confidence interval [CI] =1.468-4.388), DD genotype (P<0.0001, OR=0.239, 95% CI=0.066-0.866), the frequency of AGT T allele (P<0.0001, OR= 2.915, 95% CI= 1.666-5.097) and TT genotype (P<0001, OR=0.316, 95% CI=0.078-1.280) were significantly more prevalent among CAD patients and may be predisposing to CAD. We further found that the concomitant presence of the ACE-DD and AGT-TT genotypes increased the risk of CAD (P=0.017, OR=0.120, 95% CI=0.042-0.347).This study demonstrated the contribution of ACE (I/D) and AGT (M235T) gene polymorphisms individually or in combination to the presence of CAD risk in the Egyptian population. The ACE D allele and AGT T allele may be predictive in individuals at risk of developing CAD.

      In this paper, an interactive approach for solving multi-level multi-objective fractional programming (ML-MOFP) problems with fuzzy parameters is presented. The proposed interactive approach makes an extended work of Shi and Xia (1997). In the first phase, the numerical crisp model of the ML-MOFP problem has been developed at a confidence level without changing the fuzzy gist of the problem. Then, the linear model for the ML-MOFP problem is formulated. In the second phase, the interactive approach simplifies the linear multi-level multi-objective model by converting it into separate multi-objective programming problems. Also, each separate multi-objective programming problem of the linear model is solved by the ∊-constraint method and the concept of satisfactoriness. Finally, illustrative examples and comparisons with the previous approaches are utilized to evince the feasibility of the proposed approach.

      Numerical investigation of heat transfer characteristics in a tube fitted with inserted twisted tape swirl generator is performed. The twisted tapes are separately inserted from the tube wall. The configuration parameters include the, entrance angle (α) and pitch (H). Investigations have been done in the range of α = 180o, 160o and 140o with Reynolds number varying between 100 to 20,000. In this paper, transition - SST model which can predict the transition of flow regime from laminar through intermittent to turbulent has been utilized for numerical simulations. The computational results are in good agreement with experimental data. The results show that higher entrance angle yields a higher heat transfer value. The using of single twist twisted tape supplies considerable increase on heat transfer and pressure drop when compared with the conventional twisted tapes. A large data set has been generated for heat transfer and thermal-hydraulic performance which is useful for the design of solar thermal heaters and heat exchangers.

      P70-S6K1 & PI3K- δ kinases are identified to be involved in many physiological processes associated with cancer, therefore many of the inhibitors being designed to target these kinases are in clinical trials. In the current study we have exploited the N-9 substituted 6-(4-(4-propoxyphenyl) piperazin-1-yl)-9H-purine derivatives for their inhibitory properties with the above kinases. We have used an in silico docking study with seventeen purine derivatives for their binding affinity calculations. The binding affinities of these small molecules with P70-S6K1 & PI3K-δ were performed using AutoDock Vina. Among all the compounds, PP16 showed highest binding affinity of -14.7 kcal/mol with P70-S6K1 kinase & -17.2 kcal/mol with PI3K-δ kinases as compared to the molecules under clinical trials (PF-4708671 & IC-87114). Docking studies revealed that N-9 coumarine substituted purine derivative could be one of the potential ligands for the inhibition of P70-S6K1 & PI3K-δ kinases. Hence, this compound can be further investigated by in vitro and in vivo experiments for further validation.

      Marine macroalgae are plant-like organisms with simple internal structures that generally live in coastal areas. They mainly includedifferent communities of red, brown and green macroalgae. Marine macroalgae commonly occupy intertidal and sublittoral-to-littoral zones on rocks and other hard substrata. They are considered to be an excellent natural biosource in different aspects of agricultural fields. They have great proficiency in improving soil physical and chemical properties. Marine macroalgae are also characterized by producing a large array of biologically active biocidal substances against plant-infecting pathogens. Unfortunately, most available literatures on marine macroalgae and their derivatives mainly focused on their pharmaceutical applications but their potential utilization in sustainable agriculture development is still often regarded asa secondary goal. However, a relatively considerable dataset on marine macroalgae showed that they could play a major role in plant protection and improvement. This review summarizes different aspects of potential macroalgal applications in agriculture. Commercial production and exploitation of specific compounds with interesting biotechnological importance from marine macroalgae including microbicides, nematicides, insecticides, biofertilizers, biostimulators and soil conditioners are highlighted and discussed in detail. Bioactive compounds like fatty acids (in particular polyunsaturated fatty acids (PUFAs), proteins (amino acids), bioflavonoids, sulfated polysaccharides, carotenoids, polyphenols and carbohydrates are considered to have bactericidal, antiviral and fungicidal effects against some plant-infecting pathogens. These biocontrol agents provide multiple benefits and act as useful pointers for improving cultivation practices in diverse habitats. Marine macroalgae can be generally considered as promising multifunctional bioinoculants and ecofriendly environmental tools in recent trends of organic farming.

      Methicillin-resistant Staphylococcus aureus is a problem in both healthcare institutions and community settings. This is due to its multi-drug resistant challenges. Hence, this study assessed the prevalence of methicillin resistant gene (mecA), exfoliative toxin (eta and etb) and toxic shock syndrome (tsst-1) genes in S. aureus isolated from clinical samples. A total of 120 clinical samples of patients (urine, high vagina swab (HVS), semen, wound swab, sputum and urethral swab) from a hospital laboratory were obtained. S. aureus was isolated and then identified with API-staph kit. Antibiotic susceptibility of the isolates was determined by agar diffusion while PCR was used to detect the presence of mecA and toxin-associated genes. Fifty S. aureus isolates were obtained at frequencies of 26(52%), 12(24%), 4(8%), 3(6%), 3(6%) and 2(4%) from the HVS, urine, semen, wound, sputum and urethral swab samples respectively. All the isolates of S. aureus were resistant to the antibiotics used in this study. MecA, tsst-1, eta and etb were detected in 19(38%), 7(14%), 3(6%) and 2(4%) of the isolates respectively. The prevalence of MRSA and its resistance pattern observed in this study was a signal that the health-care workers and the general public are at risk.

      Vernonia amygdalina is a widely grown shrub plant in Africa consumed as vegetable and has high medicinal value. It has gained wide application in the treatment and management of various diseases. The leaves are useful components for herbal medicine constitution. The plant’s activities is a result of diverse bioactive compounds isolated from the different parts of the plant. These metabolites have specifically been efficacious against parasites especially worms. The mechanisms of activities include paralysis of worm, interference with energy generation and impairment with nutrient absorption, motility, and reproduction. The lack of considerable toxicity associated with the plant makes it a choice for further drug discovery. Effort should be made towards standardizing the extract(s) of V. amygdalina for use in alternative medicine for treatment of helminth-related diseases.

      Porcine reproductive and respiratory syndrome virus (PRRSV) and porcine parvovirus (PPV) infections cause significant economic losses to the pig industry and are considered the most economically important viral diseases of intensive swine production. Despite numerous reports on both diseases in several countries worldwide, the status of PRRSV and PPV in Nigeria remains largely unknown. Thus, a serological survey was conducted to determine the prevalence of PRRSV and PPV infections in pigs in Southwest Nigeria. Using commercial ELISA kits, 368 pig sera were screened for antibodies against PRRSV (types I and II) and PPV.Significantly higher antibody prevalence was obtained for PRRSV (53.8%) compared to PPV (36.1%). Since there is no vaccination against both diseases in the country, the findings of this study suggest that PRRSV and PPV are present in the pig population in southwest Nigeria. There should be continuous monitoring of pigs for these diseases in Nigeria since both viruses are associated with major economic losses in the swine industry, affecting all stages of production. This will help to ascertain the actual burden and increase awareness of both diseases to facilitate early detection in order to institute appropriate control measures in the country.

      Nalbuphine is a lipophilic opioid which could be used subcutaneously, intramuscularly, intravenously and epidurally in human, dogs and equine but not used in bucks until yet. The aim of the existing study was to compare the analgesic effect of Nalbuphine, Lidocaine and Nalbuphine – Lidocaine combination injected epidurally in bucks. Fifteen adult apparently healthy bucks were used. The animals were randomly divided into three groups (five animals in each one); group (1) was injected with Nalbuphine HCl at a dose 3mg/kg, group (2) was injected with Lidocaine HCl 2% at a dose 2.5mg / kg. Finally, group (3) was injected with Nalbuphine-Lidocaine combination at a dose (1.5mg /kg and 1.25mgkg, resp.) to evaluate the analgesic effect of each treatment. Onset and duration of analgesia were recorded after each treatment. Respiratory rate, heart rate, rectal temperature and biochemical parameters were recorded for each treatment. The results revealed that, the onset and duration of analgesia respectively were 12±2min and 200±4min in group (1), 6±1min and 80±3min in group (2) and 8±2min and 120±5min in group (3). In Nalbuphine group, No ataxia was observed while mild ataxia was observed in Nalbuphine-Lidocaine combination group but in Lidocaine treated group, sever ataxia was recorded. Heart rate increased at 90–120 and respiratory rate rectal temperature had no any significantly differentiation from baseline of any treatment. Biochemical parameters returned to basal levels through three hours after all treatments. In conclusion, Nalbuphine – lidocaine combination is useful to perform surgical operations of long duration and had effective analgesia in bucks.

      Material selection is a complex problem in the design and development of products for diverse engineering applications. This paper presents a fuzzy PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation) method based on trapezoidal fuzzy interval numbers that can be applied to the selection of materials for an automotive instrument panel. Also, it presents uniqueness in making a significant contribution to the literature in terms of the application of fuzzy decision-making approach to material selection problems. The method is illustrated, validated, and compared against three different fuzzy MCDM methods (fuzzy VIKOR, fuzzy TOPSIS, and fuzzy ELECTRE) in terms of its ranking performance. Also, the relationships between the compared methods and the proposed scenarios for fuzzy PROMETHEE are evaluated via the Spearman’s correlation coefficient. Styrene Maleic Anhydride and Polypropylene are determined optionally as suitable materials for the automotive instrument panel case. We propose a generic fuzzy MCDM methodology that can be practically implemented to material selection problem. The main advantages of the methodology are consideration of the vagueness, uncertainty, and fuzziness to decision making environment.
