  • Evaluation of asymmetry using thumbprint minutiae among Hausa population
           of Kano State, Nigeria

    • Authors: L.H. Adamu, S.A. Ojo, B Danborno, S.S. Adebisi, M.G. Taura
      Abstract: The present study was aimed at determining the existence of FA in Hausa populations using thumbprint minutiae. The participants included 112 males and 105 females of Hausa Ethnic descent, aged between 18-25 years. The minutiae of the plain thumbprints were determined from a circle with radius that cut across the nucleus of the fingerprints. The result showed that in signed asymmetry bifurcation, crossbar, break, point/dot into ridges and point/dot between ridges exhibited sexual dimorphism. The left ward asymmetry in male was exhibited in bifurcation, cross bar, trifurcation bifurcation, break, bridge, opposite bifurcation, in "M" convergence, in "M" bifurcation and Point/Dot into ridges. Similarly, in female bifurcation, trifurcation bifurcation, enclosure big, opposite bifurcation, convergence, in "M" bifurcation and return exhibit left ward asymmetry. For absolute and composite asymmetry the significant differences was observed in end, enclosure (small), bridge and return. In the entire minutiae types only ridge bifurcation exhibited directional asymmetry in males and six other minutiae types in females. In conclusion, the presence of sexual dimorphism in thumbprint ridge minutiae was demonstrated in the present study. The leftward asymmetry was observed in both sexes in different types minutiae. Females were observed to exhibit directional type of asymmetry more than the males in this population.Keywords: Asymmetry, Environmental stress, Hausa population, Ridge minutiae, Sexual dimorphism

  • Combined effect of sodium valproate and ascorbic acid on
           pentylenetetrazole-induced seizures in mice

    • Authors: A.W. Alhassan, D.K. Mohammed, M.I.A. Saleh, P.P. Mshelia, I.U. Yarube, I Lawan
      Abstract: Epilepsy is one of the most frequent neurological afflictions characterized by excessive temporary neuronal discharges resulting in convulsion. The pathophysiology is still not fully understood. Even though oxidative stress has been implicated as one of the mechanisms, yet the management of convulsions do not take into cognizance the important role played by antioxidants. The aim of the study was to assess the combined effect of sodium valproate (conventional antiepileptic drug) and ascorbic acid (potent antioxidant) in pentylenetetrazole (PTZ) induced seizures. Thirty mice were divided into six groups of five each (n=5). Group 1 served as control and administered normal saline 1ml/kg, group 2 received sodium valproate 200mg/kg, groups 3 and 4 were administered ascorbic acid (vitamin C) 100mg/kg and 300mg/kg, groups 5 and 6 were administered ascorbic acid (vitamin C) 100mg/kg and 300mg/kg respectively, in combination with sodium valproate 200mg/kg, 15 and 30 minutes prior to intra-peritoneal injection of PTZ (65 mg/kg). Seizure latency and duration were determined. The results showed that ascorbic acid alone has no effect on the seizure parameters. Sodium valproate 200mg had protective effect on PTZ-induced seizures. Combination of 300 mg/kg ascorbic acid with 200 mg/kg sodium valproate had a significant (p<0.05) synergistic and marked protective effect, as indicated by increase in the latency of seizure and reduction in seizure duration as compared to the control. Anti-oxidant vitamin C is recommended as co-treatment with sodium valproate in the management of seizures.Keywords: Pentylenetetrazole, sodium valproate, ascorbic acid, seizures

  • Effects of nitrogen levels and harvest ferquency on the growth and leaf
           quality of moringa (Moringa oleifera Lam) in Sudan Savanna of nigeria

    • Authors: U.A. Adamu, I Adamu, B.M. Auwalu, T.T. Bello, A.G. Gashua, I.A. Kurawa
      Abstract: Field experiment was conducted under irrigation at teaching and research farm of Faculty of Agriculture, Bayero University Kano, during 2011/2012 dry season to investigate the effects of different nitrogen levels and harvest frequency on growth and leaf quality of Moringa (Moringa oleifera (Lam)). The treatments consisted of four levels of nitrogen (0, 50, 100 and 150 kg N ha-1) and three times of harvest frequency (2, 3, and 4 weeks). These were arranged in a split plot design with the nitrogen levels allocated to the main plots while the harvest frequency allocated to the sub plots and replicated four times. The data collected were subjected to analysis of variance (ANOVA) using GenStat and significant different means were separated using DMRT. The result shows that application of nitrogen significantly (P<0.05) increase plant height, number of leaflets plant-1, plant stem diameter, number of branches plant-1, fresh and dry weights plant-1. Generally, the growth characters assessed gave maximum value with 150 kg N ha-1 treatment. At first harvest highest protein content of the leaf was also obtained with the higher Nitrogen level (150 kg N ha-1), highest Magnesium was obtained with 100 kg N ha-1 while highest quantity of phosphorus and potassium were obtained with 50 kg N ha-1. The increase in harvest frequency significantly (P<0.05) increased dry leaf quality of Moringa with the highest protein quality obtained from 4 weeks harvest frequency. Nitrogen and harvest frequency interaction was found to be significant (P<0.05) on dry leaf quality of Moringa.Keywords: Moringa, nitrogen, harvest frequency and leaf quality

  • Remediation of soil contaminated with toxic organic compounds using
           microorganisms

    • Authors: Ibrahim Khalil Adam, Abdullahi A. Imam, Muhammad Bello Yarima
      Abstract: Microorganisms, especially genetically modified microorganisms have continued to attract attention as a safer and environmentally friendly alternative in the bioremediation of contaminated environments such as soil and water bodies. Soil pollution by organic compounds such as pesticides, industrial and agricultural solvents, dyes, pigments, additives etc. is on the increase worldwide as a result of industrialization and agricultural modernization. Toxicity from these and other related pollutants have constituted a major challenge to humans as well as the environment. Therefore, it is important to apply effective remediation measures to reduce the levels of these toxicants so as to minimize the risk of bioaccumulation in agricultural food products. Bioremediation using biological materials viz; whole cells, cell extracts, isolated enzymes etc. is one of the most effective and environmentally friendly approaches currently in use. This paper therefore, reviews the current microbial remediation strategies of soil contaminated with various organic pollutants.Keywords: Bioremediation, Microorganisms, Pollutants, Soil, Organic

      Abstract: The effects of oral administration of ethyl acetate leaf extract of Vitex simplicifolia on vitamins A, E and C, Superoxide dismutase (SOD) and lipid profile levels in alloxan induced diabetic Wistar rats were investigated. The study was conducted with 30 Wistar rats, assigned into six groups of five rats each, and daily administration of ethyl acetate leaf extract of Vitex simplicifolia for 21 days was done. Diabetes mellitus was induced in overnight fasted rats by a single intraperitoneal injection (i.p) of 150 mg/kg body weight of alloxan monohydrate. Group 1 was the normal control group 2 was the diabetic control, group 3 was administered 10mg/kg of glibenclimide (positive control) and groups 4, 5, and 6 were administered 250,500 and 1000mg/kg body weight of aqueous leaf extracts of Vitex simplicifolia respectively. There were no significant changes (p<0.01) in the levels of total cholesterol (TC), triglycerol (TAG), low density lipoprotein – cholesterol (LDL-C), high density lipoprotein –cholesterol (HDL –C), SOD, vitamins A, E and C for the animals administered with the extract compared with the control groups. The result of this study suggests that aqueous leaf extract of Vitex simplicifolia has no antioxidant and hypolipidemic effect.Keywords: Vitex simplicifolia, SOD, Lipid Profile, Antioxidant Vitamins

      Abstract: The effects of temperature and relative humidity on the growth of three isolated fungi (Aspergillus parasiticus, Altenaria alternata and Thielavia terricola) associated with rice seedlings rot in Dadin Kowa Irrigation Scheme, Gombe, Nigeria were investigated. Temperature in the ranges of 10oC, 15oC, 25oC, 30oC, 35oC and 40oC were used to determine the temperature effect on the growth of these fungi. These fungi were also cultured on 100, 91, 80, 59.5, 47 and 32.5 % relative humidity. Highest growth of these fungi was obtained at 25oC and 30oC temperatures. The fungi showed highest growth at 80 and 91% relative humidity. The growth of these fungi was observed to increase with increase in relative humidity and vice versa. Statistical application for Sciences (SAS) was used to analyze the data generated and the least significant difference, was used to separate the means. There were significant differences (P≤0.05) in the growth of these fungi at different temperature and relative humidity regimes.Keywords: Temperature, Relative Humidity, Growth, Rice, Fungi, Dadin Kowa

    (Schum & Thonn)

    • Authors: M.F. Zubair, O Atolani, S.O. Ibrahim, O.O. Adebisi, A.A. Hamid, R.A. Sowunmi
      Abstract: The chemical composition of the leave extracts of Phyllanthus amarus (Schum and Thonn) of the family Euphorbiaceae from Nigeria was analyzed by GC-MS. The extracts were also examined for their potential to inhibit the growth of clinical isolates following standard procedure. The major compounds identified in the hexane extract are a flavonoid, flavone 4’,5,7-triethoxy-3,3’,6- trimethoxy (20.23%) and a triterpenoid 17-(1,5-Dimethylhexyl)-6-hydroxy-5-methylestr-9-en-3-yl acetate (19.02%) while bufalin (18.71%) and tetratetracontane (12.91%) were the major compounds detected in the methanol extract. Steroidal triterpenoids are the major compounds present in the extracts as it accounted for 47% of the total detectable content in the hexane extract and 52% in the methanol extract. The steroidal triterpenoids which exist primarily as acetate in the hexane extract include cycloeucalenyl acetate, ergosta-5,7,22-trien-3-ol acetate, macdougallin, 17-(1,5-Dimethylhexyl)-6-hydroxy-5-methylestr-9-en-3-yl acetate, stigmasterol and β-sitosterol while the methanol extract contains 6,7-epoxypregn-4-ene-9,11,18-triol-3,20-dione, 11,18-diacetate, bufalin, olean-13(18)-ene, methyl ursolate, barringenol R1 and 7,8- epoxylanostan-11-ol,3-acetoxy. Hexane extract of the plant exhibited antifungal activity on Candida albicans while methanol extract revealed significant antibacterial activity on Pseudomonas aeruginosa and Staphylococcus aureus at all concentrations of the extract between 12.5 and 100 mg/mL, the activity being comparable to the standard antibacterial drug, Oxacillin. The leaves of Phyllanthus amarus is a potential source of steroidal triterpenoids which could serve as biomarker for the plant species. The extracts of the plant may also serve as a natural source of antimicrobial agents for the treatment of some microbial infections.Keywords: Phyllathus amarus, antimicrobial, phytochemicals, leaf extracts

  • Geometry optimization and vibrational frequencies of tetracene molecule in
           gas phase and in methanol based on Density Funtional Theory and Restricted
           Hartree-Fock

    • Authors: A.S. Gidado, Abubakar Maigari, G.S.M. Galadanci
      Abstract: Tetracene is an organic semiconductor with chemical formula C18H12 used in organic field effecttransistor (OFET) and organic light emitting diode (OLED). In this work, the molecular geometry (optimized bond lengths and bond angles), vibrational frequencies and intensities, HOMO-LUMO Energy gap and Atomic charge distribution of the Tetracene molecule in gas phase and in solution were calculated and reported. Restricted Hartree-Fock (RHF) and Density Functional Theory (DFT) with different basis sets were employed for the task. Windows version of Gaussian 03 software was used to perform all the calculations. The results obtained show that the bond length obtained using RHF has the lowest average value of 1.072Å and that obtained using DFT has the lowest average value of 1.085Å in gas phase. In Methanol, it is observed that at RHF level, the lowest average value was 1.075Å and at DFT level was 1.087Å. This shows that the values are a bit higher in methanol than in gas phase which implies that the bonds will be slightly stronger in gas phase than in methanol. The strongest bonds in tetracene molecule are those of C20-H28, C23-H29 and C24- H30 in both gas and methanol. The weakest bonds are those of C6-C12 and C6-C14.The bond angles were found to be so closed to 1200 at both levels of theory for all basis sets used suggesting that the molecule is planar benzene in which the C atoms are sp2 hybridized. The calculated HOMOLUMO energy gap shows that the molecule will be slightly more stable in chemical reaction in gas phase than in methanol. DFT values of the energy gap appeared to be closer to the reported experimental value of 2.6eV than those obtained by RHF. The atomic charges distribution was found to be very sensitive to the basis sets which presumably occur due to polarization. From the results obtained for vibrational frequencies, it shows that tetracene molecule would be more stable in gas phase that in methanol as a result of no imaginary frequency found in gas phase. This confirms the stability of the molecule as stated in the results of HOMO-LUMO energy gap. The calculated vibrational frequencies show that the most intense frequency was obtained to be 924.9862cm-1 at 146.7973KM/mole by RHF/3-21G in gas phase while at B3LYP/3-21G, it has the most intense frequency of about 474.1260cm-1 at 390.1077.2845MK/mole in methanol.Keywords: Optimixation, Methanol, Gas, Frequency, Tetracene

  • The beneficial role of resveratrol on chlorpyrifos-induced cognitive
           impairment and lipid peroxidation biomarker in Swiss albino mice

    • Authors: B.Y. Adamu, A.W. Alhassan, M.I.A. Saleh, M Aliyu, B.T. Iliya, J Zuberu, A Yusuf, U.A. Garkuwa, I Lawan
      Abstract: Chlorpyrifos (CPF) has been associated with cognitive and psychomotor impairments in both humans and animals. This cognitive impairment has been linked to its enhanced reactive oxygen species (ROS) generating capacity. Therefore, antioxidant treatment may provide a novel therapeutic window for the management of these related impairments. The aim of this work was to evaluate the beneficial role of resveratrol on chlorpyrifos-induced cognitive impairment and lipid peroxidation biomarker in Swiss albino mice. Swiss albino mice were divided into (6) six groups of five each (n=5). Group I served as the control and were administered olive oil (2 ml/kg), group II received carboxymethylcellulose (CMC) 10 mg/kg, group III received resveratrol 30 mg/kg, group IV received chlorpyrifos (CPF) 3 mg/kg, group V received CPF (3 mg/kg) after the oral administration of resveratrol (30 mg/kg) and group VI received Vitamin E (Vit E) 100 mg/kg All administrations were done by oral gavage for a duration of 21 days. Cognitive function was assessed using Y-maze,and Novel object recognition tests and oxidative stress was evaluated using oxidative biomarkers techniques.The results obtained showed that resveratrol at dose 30 mg/kg significantly(p<0.05) improved cognitive impairment and significantly decreased (p<0.05) malondialdehyde (MDA) concentration when compared with the control. In conclusion, 30mg/kg resveratrol suppressed memory impairment, decreased malondialdehyde levels, increased catalase activity, superoxide dismutase activity and glutathione levels in our chlorpyrifos-induced cognitive impairment mice model.Keywords: cognition, chlorpyrifos, resveratrol, memory

  • Heavy metals phytoremediation using Typha domingensis Flourishing in an
           industrial effluent drainage in Kano, Nigeria

    • Authors: A. A. Mukhtar, I. L. Abdullahi
      Abstract: Phytoremediation as a tool employs aquatic macrophytes as a principal and inexpensive strategy for controlling environmental pollution. It is achieved through various mechanisms such as phytoextraction, phytostabilization, and phytovolatilization. In this study, heavy metal content of a contaminated drainage that empties into the Kano River was investigated by assessing the uptake of heavy metal contaminants by a notorious aquatic weed, “Typha domingensis”. Atomic Absorption Spectrophotometer (AAS) was used to determine the concentration of Pb, Cu, Zn, Cr and Fe in the effluent, sediment and T. domingensis in the months of January, April and July 2013, covering the seasonal weather pattern in the area. In addition, the Bioconcentration factor (BCF) of these metal pollutants in T. domingensis, were calculated as the ratio of their concentration in Typha domingensis to the effluent while the Transfer factor (TF), as the ratio of these substances in T. domingensis to the sediment. From the results, Cu, Fe and Zn concentrations were statistically different (p<0.05) in the effluent as well as in the sediment across the sampling months, while Pb and Cr were significant only in the sediment. The BCF values obtained for these metals in the test plant were >1 except for Fe in April, which indicates the plant capacity for phytoextraction. Similarly, TF values obtained were >1 except for Pb, Fe and Cu in the months of January, April and July respectively. This also indicates the potentiality of T. domingensis as a nutrient and metalaccumulating plant through the process of sequestration. The findings of this work have demonstrated the capacity of T. domingensis in the effluent drainage, not only playing an ecological role in the environment, but also to remove heavy metal pollutants. Therefore, the plant species could be used for phytoremediation of industrial effluent contaminating ecosystems.

      Abstract: The present study investigates the phytochemicals and thin layer chromatographic profile of
      Nauclea diderrichii (Rubiaceae) leaf extracts. Phytochemical in the hexane, ethyl acetate and
      methanol extracts were determined using standard chemical tests. Thin layer chromatographic
      techniques were carried out using various solvent systems of varying polarity on these extracts.
      Preliminary phytochemical screening revealed the presence of alkaloids, glycosides, saponins,
      phenolic compounds, tannins, phytosterols, carbohydrates, flavonoids and terpenoids. Further
      screening using thin layer chromatographic technique on the N. diderrichii leaf extracts also
      revealed different phytochemical compounds with different Rf values. The results obtained in
      present study indicated that Nauclea diderrichii leaf is a rich source of phytochemicals. This could justifies the use of plant species in traditional medicine for treatment of various diseases.

  • Effect of rice-husk incorporation rates on the growth and yield of tomato
           (Lycopersicum esculentum) in Mubi, Adamawa State

    • Authors: I. J. Tekwa
      Abstract: A study was carried out to determine the effect of rice-husk incorporation rates on the growth and yield of tomato (Lycopersicum esculentum) during the rainy season of 2013 in Mubi, Adamawa state. An experimental area (9.5 m × 9.5 m) was marked out into 4 blocks with 4 plots each measuring 2 m × 2 m and separated by an alley of 0.5 m between blocks and rows. The plots were treated with 3 rates (10, 20 and 30 kg equivalent to 25, 50 and 75 tons/ha) of rice-husk and a control (0 kg) that were replicated 4 times in a Randomized Complete Block Design (RCBD). Data collected on the plant growth parameters was analyzed using the generalized linear model of Statistix 9.1 for the analysis of variance (ANOVA). The results showed that there were no significant (P>0.05) differences among the treatments at 2 weeks after transplanting (WAT). However, significant (P<0.05) differences were recorded at 4, 6, and 8-WAT, except for the plant heights at 8-WAT. The tomato yield also differed significantly (P<0.05) among the treatments across the 4 harvesting intervals. It was recommended that application of 75 tons/ha should be observed for efficient growth and yield of tomato in Mubi, Adamawa State, Nigeria.

           mespiliformis Horsch (Ebenaceae) against some microbial pathogens

    • Authors: A Anas, A Ahmed, S Umar, U.M. Jajere, E.H. Mshelia, O Natasha
      Abstract: Powdered stem bark of plant material (1000g) of Diospyros mespiliformis was extracted with hexane using Soxhlet apparatus and concentrated on a water bath at 600C. The extract was later subjected to column chromatography techniques using gradient elution in which various fractions were obtained and monitored using thin layer chromatography. The structure of the isolated compound were suggested by 1D and 2D spectroscopic analysis and by direct comparison of the data obtained with those reported in literature to be Lupeol.Antimicrobial screening of the lupeol compound and control drugs were carried out using agar well diffusion method. Significant zones of inhibition of lupeol compound were observed from (30-24mm) and standard control drugs range from (40-32mm). Minimum Inhibitory Concentration(MIC) of the lupeol compound was observed at 6.25-12.5ug/ml and Minimum Bacteriacidal Concentration (MBC) /Minimum Fungicidal Concentration (MFC) ranged from (12.5-25ug/ml).Lupeol compound revealed significant antimicrobial activity against some selected clinical isolates in this study and thus validated the traditional claims ofDiospyros mespiliformis used for the treatment of antimicrobial based infections.

      Abstract: Crude oil spillage has been identified to be a regular occurrence in Upenekang village in Ibeno Local Government Area of Akwa Ibom State, Nigeria. This study has been carried out to find out the effect of crude oil spill on stream water and the environmental impact it has on the area. Using water samples obtained at varying distances from the spill site, the effects of the crude oil spill on the surface and underground stream water at the spill site were investigated by testing for the presence as well as the concentrations of toxic heavy metal pollutants. Analyses were also carried out for water conductivity, pH, temperature, hardness, total solids, total dissolved solids, turbidity, suspended solids, dissolved oxygen, carbon dioxide, COD, BOD, THC, sodium, magnesium, calcium, sulphate, nitrate, iron, copper, lead, chromium and cadmium concentrations using standard methods. The pH of all the samples of both the surface and underground stream water obtained at the spill site were observed to be acidic with very low dissolved oxygen, low COD, low BOD, high hydrocarbon content, high total dissolved solids, high water hardness and high toxic heavy metal concentrations (iron, copper, lead, chromium and cadmium) investigated for, all above admissible concentrations by World Health Organization’s standards. A one-way ANOVA showed that there is no significant influence of distance away from spill on the level of heavy metals in the water samples collected in the study area.

  • Design and implementation of an android and web-based university timetable
           customization system

    • Authors: S.H. Muhammad, B.S. Galadanci, A. Mustapha, A.S Yahaya
      Abstract: Timetabling is an essential component of scheduling in all sectors of education. University timetabling entails the scheduling of times and venues for lectures and examinations. These activities are logically structured in a time-wise manner and presented on papers and placed on notice boards in order to avoid conflicts of event. However, timetable schedule forgetfulness, misinterpretation, miscopying, cost of rescheduling and slow time to reach for the rescheduled timetables are the challenges posed by the use of paper and notice board-based timetables; hence, the need for automated timetables. In this paper, we discuss the implementation of Android and web-based timetable customization systems for the Faculty of Computer Science and Information Technology, Bayero University, Kano-Nigeria. The web-based system provides an administrative module that facilitates scheduling and rescheduling of lecture, examination and invigilation timetables. In addition, the Android timetable customization system permits the user to view, customize, set reminders and provide rescheduled timetable updates.
