      Hydrocarbon shows and seeps are frequently associated with petroleum migration through caprocks. However, leakage of petroleum from reservoirs does not necessarily result in surface seeps, nor do all occurrences of surface petroleum result from trap leakage. Cretaceous Shetland Group mudrocks which serves as caprock (seal) for the petroleum reservoir of the Heidrun Field was observed to contain liquid hydrocarbon as evidenced from UV florescence. Is this oil indigenous of the caprock or from the underlying reservoir thereby indicating possible failure of the seal' Samples from the caprock were analysed with the aim of establishing the origin of the oil stains. The investigation comprised bulk geochemical analyses in order to estimate various leakage indicators (S1 & PI). High Extractable Organic Matter (EOM) values of up to 6 mg/g rock were obtained in most of the samples. The high S1 and PI values obtained from the samples suggest oil staining. Furthermore, Iatroscan SARA analysis was used to identify compositional variability between the oil present in the caprock and the reservoir oil. The reservoir oil predominantly consisted of saturated hydrocarbons, which, in contrast, represent only a fraction of the caprock EOM. The caprock EOM is dominated by polar compounds, and the saturate fraction increases with increasing proximity to the caprock/reservoir boundary. High gas wetness of more than 80% was recorded at caprock/reservoir boundary, suggesting a good relationship between the distribution of gaseous hydrocarbons in the caprock and the gas content of the reservoir oil. The oil stains in the caprock are therefore established to be sourced from the reservoir.

      The principal components analysis and Hotelling’s T2 statistic are used in studying the clinker minerals of Portland Cement Company of Northern Nigeria (CCNN). The cement produced is considered to be a mixture of eight minerals, each being sensitive to the presence of fly ash. Effort was made in this paper to show that the dependence on only one mineral in detecting fault or diagnosing noise was not effective but rather using the entire components such that each component’s contribution to variation is measured thereby making a valid interpretation about fault.

      Leaves and stem extracts of Ipomoea aquatic Forsk were analysed for their antioxidant activities. Folin-Ciocalteu and AlCl3 methods were used to quantify total phenolic and flavonoid contents while 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical assay was used to examine the antioxidant activity of the extracts. The respective total phenolic and flavonoid contents of the stem (18.00 ± 1.20 and 20.00 ± 1.40 μg Catechin equivalent, CEQ g-1 DW) show no significant (p> 0.05) difference when compared to leaves (16.00 ± 1.10 and 30.00 ± 2.1 μg CEQ g-1 DW). In DPPH scavenging assay, the reference standard i.e. vitamin C (IC50 = 0.0660µg/ml) had significantly (p

      Investigation of the effect of taurine on the hydrolysis of para-nitrophenylphosphate (p-NPP) by rat intestinal alkaline phosphatase (ALP), L-phenylalanine inhibition of ALP and the mechanism of ALP activation by taurine as well as its role in endotoxemic injury protection was carried out. Rat intestinal ALP was exposed to taurine, and L-phenylalanine at varying concentrations and periods of time. Substrate concentration-dependent kinetic analysis was carried out at 10 mM concentration of taurine and 5.17mM of p-NPP. The concentration dependent kinetic analysis of L-phenylalanine was also investigated at 60 mM. The partially purified rat intestinal alkaline phosphatase activity was also investigated in the presence of taurine. Their interactive effect on L-phenylalanine inhibition was also analyzed. Investigation of the effect of taurine on rat intestinal ALP hydrolysis of p-NPP revealed that taurine is an activator of intestinal ALP. At 10 mM taurine and 60 mM L-phenylalanine, taurine relieved L-phenylalanine inhibition of rat intestinal ALP. The effect of lipopolysaccharide in the absence and presence of taurine on ALP activity was also carried out in vivo. The kinetic analysis of the data from the in vivo study revealed that rat intestinal ALP activity is higher (12x10-3nmol-1min-1mg protein) in the presence of taurine and LPS when compared with the activity in the presence of LPS (9x10-3nmol-1min-1mg protein) or taurine (8.8x10-3nmol-1min-1mg protein) alone. From this study, it may be concluded that the activation of rat intestinal ALP by taurine may be one of the mechanisms of endotoxemic injury protection.

      Whether or not low CD4 count directly contributes to stroke among HIV infected stroke patients is yet to be elucidated. This study aimed to ascertain the role of low CD4 count in the pathophysiology of stroke in HIV infection. This was a hospital-based, case-control study. Sixty five (65) consecutive stroke patients (36 males and 29 females) aged 20-68 years and sixty five (65) age-and-sex matched controls were enrolled. A structured questionnaire was administered. Neurological examination was performed and computed tomography scan of the brain done. Blood samples were taken for HIV 1&2 screening using ELISA method. Positive test using two different kits constituted a positive result. CD4 count was determined by western blot method. The mean CD4 count of HIV positive stroke patients (224.92 cells/cm3) is significantly lower (P

      The effect of toxic substances on aquatic lives from a wastewater indiscriminately discharged into the environment during oil and gas exploration activities in Nigeria is the focus of this study. A plant bioassay, the Allium cepa test, was used for the cytogenotoxicity screening of process water on root growth inhibition and chromosome abnormalities in the meristematic roots of the plant. Results of the physicochemical analysis of the wastewater collected from Nigerian Agip Oil Company (NAOC) facility at Ogboinbiri in Bayelsa State at the point of discharge into the environment showed that it had an unpleasant odour, was slightly alkaline (pH 7.72) and had high electrical conductivity (2793.33 µS/cm). Lead, manganese, iron, chromium and nickel were present at amounts (0.13, 0.33, 4.47, 0.17 and 0.10 mg/l respectively) above national (NESREA) and international (USEPA) limits for effluent discharge.

      This study examined the role of IFAD/CBARDP on improving rural women’s livelihood in Kebbi State, Nigeria. Multistage sampling technique was adopted to select 80 IFAD participating women. Structured questionnaire was used in data collection. Descriptive statistics was used to present the data obtained. Majority of the women were married, and at active productive ages. Qur’anic education was the common educational status of the participants. The findings also reveal that all the IFAD participating women were provided with assistance based on needs and interest and the common assistance provided was the training on tailoring, knitting, soap and cream making and later the participants were provided with such machines. In addition, the participants were also provided cash loan. The programme has lead to improvement of the living standards of the participants after programme participation. Attitudinal dispositional test using 3 points Likert’s scale reveal that the participating women strongly agreed that the programme has improved their living standard, the loan was adequate, and all the assistance provided was based on their needs and interest. It is concluded that the participating women were involved in decision making, most especially on the assistance provided, and the management of the assistance. It’s recommended that effort should be geared towards increasing women participation in any intervention programme that could uplift the livelihood of the rural communities.

      Neocarya macrophylla belongs to the Chrysobalanaceae family and is extensively used in folk medicine as an antibacterial, antivenin, antiasthmatic, anticancer, analgesic and anti-inflammatory agent. This study was aimed at isolation and characterization of compounds from the stem bark of Neocarya macrophylla. Pulverized plant material was exhaustively extracted with methanol using maceration method and concentrated in-vacuo with the aid of rotary evaporator at 40oC to afford a reddish brown crude methanol extract (ME). The methanol extract was successively partitioned into hexane, dichloromethane, ethylacetate, n-butanol and aqueous fractions. Stigmasterol was isolated from the hexane fraction and a catechin glycoside, Bis-(5,7-diacetyl-catechin-4’-α- rhamnopyranoside) was isolated from the ethylacetate soluble fraction using a combination of silica gel column, gel filtration (sephadex LH-20) and preparative thin layer chromatography. The structures of the compounds were established on the basis of chemical tests, spectroscopic analysis and by comparison with reference spectral data.

A total of 315 stool samples were collected; 205 samples were obtained from confirmed HIV/AIDS positive patients and 105 samples from HIV negative patients. These samples were examined using saline preparation, iodine preparation, formol ether concentration technique and modified cold Ziehl Neelsen staining technique. The prevalence rate of parasitic infection in HIV positive patients was 20.5% with the following parasites Cryptosporidium parvum 19(9.3%), Hookworm 6(2.9%), Giardia lamblia 13(6.3%), Taenia spp 2(1%), and Entamoeba histolytica 2(1 %). While in the HIV negative patients examined, the prevalence of parasitic infection was 11.8% with the following Hookworm 5(4.5%), E. histolytica 2(2%), G. lamblia 3(3%) and Ascaris lumbricoides 3(3%). Gender distribution of the intestinal parasitism shows that male patients had 17% infection rate while in the female group 3% infection rate was recorded. There is no significant (P>0.05) association between the gender and parasitic infection.

      This study investigated the in vitro antioxidant activity and phenolic content of aqueous and ethanol extracts of Alstonia boonei and Eupatorium odoratum leaves. Total phenol, flavonoid and flavonol content of the extracts were estimated to determine the levels of phenolics in the extracts. The antioxidant capacity of the extracts were assessed through diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging activity, ferric reducing antioxidant power (FRAP) and reducing power (RP). The results revealed that the DPPH radical scavenging ability of aqueous extract of E. odoratum (with IC50 = 0.07± 0.003mg/ml) compares favourably with that of the standard ascorbic acid (IC50 = 0.06 ± 0.01 mg/ml). There was a dose-dependent increase in FRAP and RP capacity in all the extracts. The ethanol extract of E. odoratum had the highest FRAP while the aqueous extract of A. boonei showed the highest RP ability when compared with the other extracts. However, flavonol content was highest in the aqueous extract of E. odoratum followed by ethanol extract of A. boonei. The phenolic and flavonoid contents of extracts of E. odoratum were higher than that of A. boonei extracts. This study, therefore, reveals that aqueous extract of A. boonei and ethanol extract of E. odoratum leaf are more effective free radical scavengers and antioxidants relative to the other extract forms. These findings support the use of these extracts as potential sources of natural antioxidants.

      Determination of antinutrients and toxic substances in leafy vegetables is an imperative facet in nutritional studies as it establishes the baseline concentrations index for phytotoxins in the vegetables. Concentrations of cyanide, nitrate, soluble and total oxalates were quantitatively determined in the common leafy vegetables (Amaranthus cruentus, Hibiscus sabdariffa, Corchorus olitorius, Telfairia occidentalis and Vernonia amygdalina) consumed in Minna, Niger State, Nigeria, using colourimetric and titrimetric methods. The results show that the concentration of cyanide in the leafy vegetables is within the permissible level of 200 mg/kg fresh weight while the concentration of nitrate in V. amygdalina and H. sabdariffa is within the acceptable daily intake of 219.00 mg/day, those of A. cruentus, C. olitorius and T. occidentalis is enough to induce toxicity in man. The soluble and total oxalates content in the vegetables are higher than the permissible level except that the concentration of soluble oxalate in H. sabdariffa is within the acceptable level of 250 mg/100 g. The results suggest that while the concentrations of cyanide in the analysed vegetables and nitrate in V. amygdalina and H. sabdariffa are safe for consumption, the concentrations of soluble and total oxalates in the vegetables and nitrate in A. cruentus, C. olitorius and T. occidentalis may contribute to nutritional problems if ingested without proper processing.

      Nutrients availabilty is one of the major contributors to distribution and growth of phytoplankton species. Physicochemical properties and phytoplankton species and their distribution in Shagari Reservoir were evaluated. Standard methods of UNEP were used to determine monthly physicochemical flux properties, diversity and distribution of phytoplankton species were also determined. Phytoplankton classes identified included Bacillariophyceae, Chlorophyceae, Cynophyceae and Dinophyceae. Class Chlorophyceae had the highest annual percentage distribution (37.55%) with four species identified. The least monthly percentage (7.64%) was recorded in November by Dinophyceae. Anabaena wisconsineae (Dinophyceae) had the highest frequency of occurence (96.6%). August, September and October were the most turbid months using Secchi disc measurement with 8.30, 9.0 and 9.8cm respectively. The monthly variation in the physicochemical parameters may be due to seasonal changes and human activities. The levels of nitrogen and phosphorus ranged from 0.30-7.30 Mg/l and 0.1-0.8Mg/l respectively. The reservoir has low species of phytoplankton, which may be due to low levels of nutrients and age of the reservoir.

      Rubella infection is generally mild in children. However, infection during pregnancy can leads to fetal death or congenital defects known as Congenital Rubella Syndrome. The seroprevalence of IgG to rubella virus was determined using Enzyme Linked Immunosorbent Assay among 400 pregnant women between the ages of 15-45 years attending ante-natal clinics in Kaduna metropolis. Of the 400 samples tested, consisting 20 in their first trimester, 260 in second and 120 in third trimester, 386 (96.5%) were IgG seropositive. Seroprevalence of 95.2% - 100% was obtained across the age groups. In relation to stages of pregnancy 19 (95.0%), 251 (96.5%) and 116 (96.7%) were seropositive in 1st, 2nd and 3rd trimesters respectively. The seroprevalence obtained in this study indicates that majority of the pregnant women had protective antibody due to previous exposure to the virus. However, 3.5% of the pregnant women were susceptible. Therefore, there is a need for government to incorporate rubella vaccine to be part of national immunization programme and screening of women of childbearing age so as to reduce subsequent burden of congenital rubella.

      The present study was conducted to evaluate the hepatotoxic and nephrotoxic effects of petroleum fumes on male and female petrol attendants. Investigations had been carried out on thirty (30) adult petrol attendants from different filling stations in Ibadan metropolis of Nigeria with ten (10) healthy adults as control. All the subjects involved in this study were between the ages of 27-35 years. The subjects were grouped according to the duration of time they had worked in the filling station. Serum aspartate amino transferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP) activities and total bilirubin concentration were determined to evaluate hepatotoxicity. Kidney function tests were also evaluated using serum creatinine, total protein and urea level. Electrolytes (potassium, chloride and sodium ions) leakages into the serum were also evaluated. The results reveal that serum AST, ALT, ALP activities and total bilirubin concentration in the petrol attendants were significantly (P
