Abstract: The strategy developed for sex determination in skeletal remains is to amplify the highly degraded DNA, by use of primers that span short DNA fragments. To determine sex of unembalmed human cadaveric skeletal fragments from Sokoto, North-western Nigeria, using Polymerase Chain Reaction (PCR). A single blind study of Polymerase Chain Reaction (PCR)-based sex determination using amelogenin gene and alphoid repeats primers on unembalmed human cadaveric skeletal fragments from Sokoto, North-western Nigeria, was undertaken. With amelogenin gene, genetic sex identification was achieved in four samples only. PCR Sensitivity = 40%, Specificity = 100%, Predictive value of positive test = 100%, Predictive value of negative test = 25%, False positive rate = 0%, False negative rate = 150%, Efficiency of test = 50%. Fisher's exact probability test P = 1. Z-test: z-value = -1.0955, p>0.05; not statistically significant. With alphoid repeats primers, correct genetic sex identification was achieved in all the samples. PCR Sensitivity = 100%, Specificity = 0%, Predictive value of positive test = 100%, Predictive value of negative test = 0%, False positive rate = 0%, False negative rate = 0%, Efficiency of test = 100%. Fisher's exact probability test P = 1. Z-test: z- and p values were invalid. The study, has demonstrated the applicability of PCR method of sex determination in unembalmed human skeletal fragments from Sokoto, Northwestern Nigeria. With amelogenin gene primers, correct genetic sex identification was achieved in four samples only. With alphoid repeats primers, correct genetic sex identification was achieved in all the samples. Therefore, alphoid repeats is more efficient and more reliable than amelogenin gene, in sex determination from unembalmed human skeletal fragments. This is the first known study determining the sex of unembalmed human skeletal fragments by means of PCR in Nigeria. There is need for further studies in Nigeria to complement the findings of this study.

Abstract: The detection of Escherichia coli as an indicator of faucal contamination in drinking water sources in Amassoma town, a host Community of the Niger Delta University, Bayelsa State in the Niger Delta of Nigeria, was carried out to determine their suitability for drinking. Result obtained showed mean total coliform bacterial counts of 2.05 x103 cfu/ml for borehole water, 1.25x103 cfu/ml for well water and 1.0x103 for pipe borne water. The mean count of faecal coliform was 2.1x103 cfu/ml for borehole water, 4.5x10 cfu/ml for well water and 1.0x10 cfu/ml for pipe borne water. The faecal coliform identified was Escherichia coli. Sources of contamination were found to be septic tanks, waste dump sites and periodic flooding of the area, being a typical wetland environment. It was concluded that water from the different sources studied in Amassoma did not meet the world health Organization (WHO) standard for drinking water. This study has therefore shown the need for continuous monitoring of our water supply systems.

Abstract: Rauwolfia vomitoria is a natural medicinal plant which has been used over the years for the treatment of various ailments. The effects of extract of rauwolfia vomitoria on liver enzymes of carbon tetrachloride induced hepatotoxicity were observed in adult wistar rats weighing between 120g and 190g. They were divided into four groups A,B, C and D of six rats each. Group A served as the control and received 0.41ml of distilled water. The experimental groups B, C and D received different doses of drugs as follows : group B received 0.50ml of rauwolfia vomitoria extract, group C received 0.5ml of carbon tetrachloride and group D received 0.41ml of carbon tetrachloride + 0.4ml of rauwolfia vomitoria extract. The drugs were administered once in a day using intubation method for a period of twenty one days. Twenty four hours after the last administration, the animals were anaesthetized under chloroform vapour and dissected . liver tissues were removed and weighed. Blood samples were collected by cardiac puncture and Serum samples were separated from clot by centrifugation using bench top centrifuge. Activities of serum aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase were determined using randox kit method. The relative liver weight for carbon tetrachloride treated group were significantly higher (p<0.001) than the control and groups B and D. serum aspartate aminotransferase, alanine aminotraansferase and alkaline phosphate level of group C were statistically higher (p<0.001) than the control. The extract exhibited a liver protective effect against carbon tetrachloride induced hepatotoxicity.

Abstract: This study was conducted purposely to evaluate the effects of shea butter effluent (SBE) on the freshwater inhabitant using Clarias gariepinus as a biological model. A prominent Local factory of shea butter at Tede, ATISBO Local Government was chosen because the effluent flows directly into a near-by stream that ends up at a popular Dam in the Local Government on which more than 120,000 people depend for domestic use.Static bioassay was conducted to determine the LC50 of shea butter effluent to Clarias gariepinus. Ten fishes each were exposed to 0.05, 0.06, 0.07, 0.08, and 0.09ppt (lethal concentration) of SBE in separate water plastic bowl of (40cmX29cmX28cm) of 60litres capacity.The lethal Concentration (LC50) value of SBE was 0.057ppt for 96hrs of exposure. Total mortality occurred in the concentrations of 0.08 and 0.09ppt within 24hours of exposure period. Behavioural reactions exhibited by the fish include erratic movement, air gulping, loss of reflex, molting, barbell deformation, hemorrhage, and excessive mucus secretion in fish exposed to higher concentration of shea butter effluent. The appreciable increase in the mean value of heavy metal, such as Manganese, Nickel, Cadmium, Zinc, Copper and Lead revealed that the increase in the concentration of shea butter effluent leads to bioaccumulation of the aforementioned heavy metals in the test organisms. The values for all the metals exceed the permissible Criteria of the national and international regulatory body. Therefore, Shea butter effluent is highly toxic to freshwater fishes, its discharged directly into water bodies, new fish farms or in areas close to aquatic environment should not be encouraged.

Abstract: The present study was carried out to investigate the patterns of esterase isozymes extracted from the silk gland, haemolymph and mid gut of Eri silkworm (Samia Cynthia ricini). The qualitative analysis of esterases was carried out by 7.5% of native Polyacrylamide Gel Electrophoresis (PAGE). The inhibitor sensitivity of the enzymes towards paraxon, eserine and pCMB was used to classify the individual zones of esterases. Three zones of esterases were observed in different tissues of Eri silkworm. Silk gland esterases were classified as CHsp (Cholinesterase like enzymes) esterases. The haemolymph and mid gut esterases were classified into Esdp (Enzyme inhibited by paraxon and pCMB).

Abstract: Perinatal HBV transmission is common in South East Asia approximately 25- 30% of the carrier pool. The problem is not only to the mother but also pertains to the offspring, in pregnancy hepatitis; the immune alterations in pregnancy may modify the dynamics of the disease. The infants of the mothers, who are carrying both HBsAg and HBeAg, have the highest risk of acquiring the HBV infection by the perinatal route. The over all risk may vary from one population to another, depending on the prevalence of HBeAg positivity in the pregnant women. It is reported and estimated that 22,000 pregnant women in the United States get infected with hepatitis B virus, which necessitated hepatitis B vaccination of the newborn mandatory in the United States. This study was aimed to bring about authenticated documentation on impact of preventive measures by vaccination that are essential features to plan and implement health measures package in a country. Results: Inspite of neonatal vaccination against hepatitis B given to all 158 children born to their HBsAg positive mothers, 6.8% (6/87) of these infants reached the status of chronic HBV infection from their infected mothers after 12 months follow-up. Conclusion: 6.8% (6/87) of the infants developed chronic HBV infection in spite of hepatitis B vaccination all the children by acquiring HBV from their infected mothers as confirmed by twelve months of follow-up.

Abstract: Present study was conducted to determine the baseline widal titer of healthy population of Dehradun city. A total of 300 serum samples were collected from healthy individual with no history of fever and who had not received any vaccination for enteric fever. Tube agglutination test was done with commercially available antigens which contained the Salmonella enterica serovar typhi O and H antigens, the Salmonella enterica serovar paratyphi AH antigen and paratyphi BH antigen. In the present study an agglutination titer for TO – 1:20 is 28%, for 1:40 is 24%, followed by 1:80 and 1: 160 which is 10%, 4% respectively. The highest sample with an anti-H titre found with 1:20 (22%) followed by 1:40(17%). Based upon the results of the study it has been recommended that a single Widal can be significant in an endemic region when higher titre (1:160) is obtained.

Abstract: Iron is a component of a number of proteins including haemoglobin, myoglobin, cytochromes and enzymes involved in redox reactions. Inadequate iron intake can lead to varying degrees of deficiency, from low iron stores to early iron deficiency and iron-deficiency anaemia and this is dangerous to both baby and mother. The objective of this study is to assess the prevalence of iron deficiency and iron deficiency anaemia among pregnant women in Calabar, Cross River State Nigeria. Seventy pregnant women within the age range of 15-45 years from University of Calabar Teaching Hospital were recruited as subjects in this study. The control consisted of fifty age-matched apparently healthy non-pregnant women . The tests that were carried out using standard method include include full blood count (packed cell volume, haemoglobin, mean cell haemoglobin, mean cell haemoglobin concentration and red cell count), serum iron, total iron binding capacity, transferrin saturation,serum ferritin and soluble transferrin recptor. The prevalence of anaemia and iron deficiency anaemia were found to be significantly higher (p<0.05) among pregnant women(20.0%, 15.7%) when compared to non-pregnant women. The mean haemoglobin, haematocrit, serum iron, serum ferritin and transferrin saturation were significantly reduced (p<0.01) in pregnant than non-pregnant women while total iron binding capacity and soluble transferrin receptor significantly (p<0.01) increased in pregnant than non-pregnant. It was also shown that pregnant women in their third trimesters and multigravidae had the highest prevalence of iron deficiency and iron deficiency anaemia while pregnant women in their second trimester had the highest prevalence of anaemia. In conclusion the study has shown that the prevalence of anaemia, iron deficiency and iron deficiency anaemia among pregnant women in the studied area were still high and can be considered public health problem.

Abstract: This study aims to evaluate the effects of the eccentric physical training's time on daily plasma concentrations of testosterone among sedentary athletes. Sixty male athletes, with homogeneous age, size and weight were selected for the study during three months. They were subjects to a strength training of the extensor and flexor muscles of the knee. After they were divided in two groups of thirty subjects and then had physical training either in the morning between 6 and 7, or in the evening, between 16 and 17. The dosage of testosterone on each athlete was performed before and after submission to an eccentric physical program at the antecubital vein in a restful sitting. Our results have shown that eccentric physical training induces the increase of this steroid hormone in the two groups of athletes and the training in the evening promotes better its production. Our results also showed that the rate of this androgen drop significantly during the day in both groups of athletes trained in the morning or in the evening as well as their respective controls. However, the decline was even more pronounced for subjects trained in the morning.

Abstract: This study was concerned with the investigation of acute pharmacological responses (pharmacodynamics) including analgesic and anti-inflammatory effects of ketorolac tromethamine fast dissolving tablets prepared by direct compression method using 3% croscarmellose sodium as a superdisintegrant by applying tail flick test and carragenan induced rat paw edema test respectively. Also, the work aimed to develop a sensitive LC-MS/MS method for simultaneous determination of ketorolac tromethamine in human plasma samples released from fast dissolving tablets. Also, to estimate whether the prepared tablet dosage form increases the bioavailability of ketorolac tromethamine in the body compared to marketed conventional tablet. From this study, it could be inferred that ketorolac tromethamine fast dissolving tablets (G5) containing (3% corscarmellose sodium as a superdisintegrant, 30% Avicel pH102, 5% aspartame, 1% talc, 1% magnesium stearate, and mannitol Q.S.) and prepared by direct compression method could be considered as a promising formula to enhance bioavilability of the drug.

Abstract: The demand for mouth dissolving tablets has been growing during the last decade especially for elderly and children who have difficulties in swallowing. Ketorolac tromethamine is an effective anti-inflammatory agent that has been extensively used for the prevention of pain and inflammation associated with a wide variety of reasons. This study was aimed to form Ketorolac tromethamine mouth dissolving tablets by direct compression using superdisintegratants as crospovidone (CP) ,crosscarmellose sodium (CCS), and sodium starch glycolate (SSG) at concentrations of 3%, 6%, 9%, and 12%. The physical mixtures of the drug and the used excipients were evaluated for their micromeretric properties such as angle of repose, particle size, Hausner's ratio and % compressibility. Also, FTIR spectroscopy and DSC calorimetry were performed to indicate any possible interaction between the drug with the used excipients.All the prepared tablets were evaluated for their weight variation, thickness, hardness, wetting time, and disintegration time. Also in-vitro release study was done for all the prepared tablets using distilled deionized water as dissolution medium at 37.5± 0.5 c˚. Based on in-vitro release study and stability studies, G5 (contained 3% CCS) was found to be the promising formulae and subjected to further studies.

Abstract:In the present investigation partially purified alkaline protease from Aspergillus sp. As#6 and As#7 strains were entrapped in calcium alginate beads and characterized using casein as a substrate. Temperature and pH maxima of protease from As#6 strain showed no changes before and after immobilization and remained stable at 450C and pH 9, respectively. However km value was slightly shifted from 4.5mg/ml to 5 mg/ml. Proteases from As#7 strain showed shifting in pH optima to a more alkaline range (10.0) as compared with free enzyme (9.0). Optimum temperature for protease from As#7 strain showed changes after immobilization and shifted from 650C to 850C. However there was no significant effect on Km value but Vmax of immobilized protease from As#7 strain was also shifted from 200U/ml to 370U/ml. Immobilized protease from As#6 strain was reused for 3 cycles with 22% loss in its activity whereas immobilize protease from As#7 strain was reused for 3 cycles with 17% loss in its activity. Protease from As#7 strain has a higher affinity for the substrate and higher proteolysis activity than protease from As#6 strain. The present work concludes that Aspergillus As#7 strain may be a good source of industrial protease.

Abstract: The present study examined the effects of artesunate –amodiaquine combination therapy on spatial memory and anxiety- related behaviors in healthy Swiss mice. Neurobehavioural models used were the Y maze and elevated plus maze. Selected for the experiments were eighty adult mice weighing 20-25 g. Forty animals were used in each behavioral model; they were randomly assigned into five groups A, B, C, D and E. Group A served as control and received normal saline, groups B, C and D received artesunate (4 mg/kg), amodiaquine (10 mg/kg) and artesunate- amodiaquine combination(4 mg/kg and10 mg/kg) respectively while group E animals were given diazepam (5mg/kg). Drugs and vehicle were given orally for three days. The animals were exposed to the elevated plus maze (EPM) and the Y-maze on day 1 immediately after administering the first dose and day 3 immediately after the last dose, the number of entries and percentage time spent in the open and closed arms after five minutes' exposure to the plus maze and Y–maze spontaneous alternations over a five minute period was scored for each animal. Statistical analysis was carried out using a one way ANOVA followed by a post-hoc test. Results of elevated plus maze tests revealed a significant increase in number of open arm entries and percentage time spent in the open arm and a significant reduction in the total number of arm entries compared to control; Y-maze task performance showed a significant reduction in percentage correct alternations compared to control .In conclusion artesunate- amodiaquine administered over a three day period had anxiolytic and memory retarding effects in healthy mice thereby giving an insight into the possible behavioral effects in humans.

Abstract: In this work, comparative analysis of two biodegradable oils (neem seed oil and watermelon seed oil) were compared with conventional quenching oil (mineral oil) for heat treatment of steel. The plain carbon steel of 0. 37%C of 25 mm diameter was austenitized at different temperatures (800, 830, 850, 880, and 9000C) for 1 hr, quenched separately in these respective oils and tempered at different tempering temperatures (250, 270, 300, 330, 350 and 4000C) for 1 hr, thereafter cooled to room temperature in these oils. The microstructure resulted by different conditions have been correlated with mechanical properties through optical microscopy. The results indicate that the mechanical properties and microstructural features are affected by tempering temperature and austenitizing temperature on both quenchants. The tensile strength, hardness and retained austenite of tempered samples drop as the tempering temperature increased. However, the impact strength increases with increasing tempering and austenitizing temperature, indicating improvement of ductility. Microstructural observations reveal that the carbide precipitates have a plate-like structure at lower tempering temperatures, but are spheroid-like at high temperatures on both quenchants, but less pronounced on watermelon oil.

Abstract: The prevalence of cleft lip and palate in University of Abuja Teaching Hospital from December 2000 to December 2010 was investigated in this works and was found to be 3.2 in every 1,000 live birth. This is very high as compared to reports from earlier works but was suspected to be due to the smile Train Project which is a private sector driven initiative that takes up the burden of paying for cleft lip and palate repair. Left sides clefts of the lip and palate were found to be almost twice that of right sides cleft of the lip and palate. This was in keeping with reports from earlier works. This study shows there is need for further studies in the field of cleft lip palate in all regions of the country.
