Effect of Computer Simulation and Jigsaw Technique in Teaching Reproductive System in Human in Senior Secondary Schools Minna Metropolis, Niger State
The conventional method of teaching is most common in Nigeria and researchers have shown that this method has led to poor performance of students in Biology and in other subjects. Researchers have been able to ascertain that students will learn best when they participate in the teaching-learning process. This study examined the effects of Computer simulation and jigsaw technique on the performance of senior secondary school students in Biology in Minna metropolis, Niger state. The study also investigated gender differences in the performance of Male and Female students in Biology. The sample used consists of seventy-eight (78) Senior Secondary (SSII) Biology students. Twenty-six (26) students consisting of thirteen (13) males and thirteen (13) females were randomly selected from each school. The schools were randomly assigned to Experimental group 1, Experimental group 2 and Control group. Experimental group 1 (n=26) was treated with jigsaw technique, experimental group 2 (n=26) was treated with computer simulation, while the control group (n=26) was treated with convectional teaching method. Quasi-experimental design employing pre-test, treatment and post-test was adopted. The test instrument used for the study was a twenty (20) multiple-choice Biology Achievement Test (BAT) questions. The test had a reliability index of 0.72 determined using split- half reliability approach. The data collected were analyzed using Analysis of Variance (ANOVA), t-test, mean, standard deviation and mean gains. Three null hypotheses were tested at 0.05 level of significance. Treatments used had significant effects on students’ Post-test achievement score. Students exposed to Computer simulation and jigsaw technique performed better than their counterparts who were taught with conventional teaching method (F=8.811, df=2, 75 P<0.05). There was no significant difference in the performance of the Male and Female students taught with both Computer simulation and jigsaw technique. Based on the findings, it was recommended, among others, that biology teachers should adopt computer simulation technique and jigsaw technique in teaching Biology concepts in view of its high facilitative effect on students’ performanc

PARTIAL CHARACTERIZATION OF PROTEASE EXTRACTED FROM “YATSIN BIRI” GINGER (Zingiber officinale) CULTIVAR OF NORTHWESTERN NIGERIA
enzymes for cheese making and related processes have ignited a flame of scientific enquiries on the possibility and suitability of their substitution by other enzymes of plant sources. In this study, ammonium sulphate fractionation, characterization and milk clotting activity (MCA) of protease extracted from YatsinBiri ginger rhizome cultivar of the family Zingiberaceae from northwestern Nigeria were analysed. The protease extracted showed optimum activity at 50 °C and pH value of 5.5. Relative activity of the enzyme was also observed within a broad pH range of 4.5 to 7.0 accordingly. The enzyme was completely denatured at 100 °C and alkaline pH of 11.5. The milk clotting property of the protease indicated 2.83 and 1.81 folds of MCA and MSCA respectively in relation to commercial calf rennet with MCA/PA ratio of 2.18. These properties of YatsinBiri ginger protease, especially its milk clotting activity, broad pH ranges and moderately elevated temperature of 50 °C, may favour its suitability as substitute calf rennet in the food industries, especially incheese making and related product

Effect of Aqueous Leaf Extract of Borreria verticillata Species of Sudano-Sahelian Savanna on CCl4 Induced Hepatotoxicity
Preliminary phytochemical screening of Borreria verticillata species of Sudano-Sahelian savanna and the effect of aqueous leaf extract of the plant were studied in CCL4-induced hepatotoxicity rats. Screening of the aqueous extract indicates the presence of alkaloids, flavonoids, tannins, glycosides, sterol and saponins. While athraquinone was absent. Serum levels of aspartate aminotransferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP), total protein (TP) and bilirubin (BL) were analysed in rats intraperitoneally administered with 100 mg/kg CCl4 followed by oral treatment with 300mg/kg of aqueous leaf extract of B. verticillata for 48 and 96hrs. The rats treated for 48 hours after had serum AST, ALT, ALP, TP and BL levels not statistically different (P>0.05) compared to both normal control and positive control (treated with 100mg/kg standard drug) although the value of positive control was slightly lower than the test values. However, the test values were statistically lower compared to toxicity control at P< 0.05. The serum AST, ALT, ALP, TP and BL levels when the treatment was extended to 96 hours showed similar pattern to 48 hours treatment. Even though the test values with respect to the enzymes activity were slightly lower in the extended treatment. This result indicates the hepatocurative properties of aqueous leaf extract of B. verticillata on CCL4-induced hepatotoxicity rats, which could be attributed to its phytochemical contents.

In-silico Investigation of the Interaction between Beta-class Glutathione S-Transferase and Five Antibiotics, namely; Ampicillin, Tetracycline, Chloramphenicol, Ciprofloxacin and Cephalexin
Glutathione s-transferases(GSTs) are enzymes involved in the conjugation and deactivation of various xenobiotics including drugs. Thisin-silico study was undertaken in order to investigate the interaction between beta-class glutathione s-transferase and five selected antibiotics, namely; ampicillin, tetracycline, chloramphenicol, ciprofloxacin and cephalexin using molecular docking study. RaptorX server was used to predict the amino acids involved at the binding sitewhile molecular docking study was employed in order to investigate the binding interactions.RaptorX predicted several amino acids which were different from the ones observed in molecular docking because of the variability in the substrate binding site of GSTs however, all the amino acids predicted by RaptorX were also found to be involved in the GSH binding.Lys107, Phe109, Ser110, Leu113, Trp114, His115 and Arg123, Leu168 were the amino acids involved in the binding of various antibiotics to the substrate binding site of the protein while Ala9, Cys10, Leu32, Tyr51, Val52, Pro53, Glu65 and Ala66were involved in the binding of the co-substrate GSH to the binding site of the protein. The results indicated that all the antibiotics showed a good binding affinity with the beta class GST and are therefore capable of deactivating the drugs. With these, finding a beta class GST inhibitors alongside antibiotics during a treatment of diseases will be of beneficial in the current fight against antibiotic resistance
