Abstract: Testes from nine male Malin x Santa-Ines rams with an average body weight of 43.1+/-3.53 kg, were used to study the effects of palm kernel cake (PKC) based diet on spermatogenic cells and to assess copper (Cu) levels in liver, testis and plasma in sheep. Animals were ided into three groups and randomly assigned three dietary treatments using restricted randomization of body weight in completely randomized design. The dietary treatments were 60% palm kernel cake plus 40% oil palm frond (PKC), 60% palm kernel cake plus 40% oil palm frond supplemented with 23 mg/kg dry matter of molybdenum as ammonium molybdate [(NH(4))(6)Mo(7)O(24).4H(2)O] and 600 mg/kg dry matter of sulphate as sodium sulphate [Na(2)SO(4)] (PKC-MS) and 60% concentrate of corn-soybean mix+40% oil palm frond (Control), the concentrate was mixed in a ratio of 79% corn, 20% soybean meal and 1% standard mineral mix. The results obtained showed that the number of spermatogonia, spermatocytes, spermatids and Leydig cells were not significantly different among the three treatment groups. However, spermatozoa, Sertoli cells and degenerated cells showed significant changes, which, may be probably due to the Cu content in PKC. Liver and testis Cu levels in the rams under PKC diet was found to be significantly higher (P<0.05) than rams in Control and PKC-MS diets. Plasma Cu levels showed a significant increase (P<0.05) at the end of the experiment as compared to at the beginning of the experiment for PKC and Control. In conclusion, spermatogenesis is normal in rams fed the diet without PKC and PKC supplemented with Mo and S. However spermatogenesis was altered in the PKC based diet probably due to the toxic effects of Cu and the significant changes in organs and plasma. Thus, Mo and S play a major role in reducing the accumulation of Cu in organs.

Abstract: Interpersonal violence has devastating consequences for the mental, physical and sexual health of the victim. It is a leading cause of injury in east Africa. Studies in Ethiopia report that the most common cause of injury was interpersonal conflict. Our objective was to study the incidence of interpersonal violence related injury and associated factors among patients visiting the emergency department of University of Gondar Hospital, Northwest Ethiopia. A cross-sectional institutional based study design was employed from November 2013-June 2014. The source population was a cohort s le of all patients presenting for treatment of a traumatic injury. Data were collected using injury surveillance guidelines developed by the World Health Organization. Bivariate and multivariate logistic regressions were performed to identify the presence and strength of association. Odds ratio with 95% confidence interval was computed to determine the level of significance. The overall incidence of interpersonal violence related injury was 28.5% of all emergency department trauma patients. Multivariate logistic regression shows that conflict in the family prior to the event [AOR = 9.9 (95% CI: 4.433-9.536)], poor behavioral control [AOR = 2.5 (95% CI: 1.192-5.460)], alcohol use [AOR = .406 (95% CI: 1.813-6.398)] and paternal education [AOR = 2.441(95% CI: 1.209-4.929)] were found to be independently associated with interpersonal violence related injury. The incidence of interpersonal violence related injury was high. Counseling and education on conflict resolution methods should be given for the community using mass media.

Abstract: Conjugated linoleic acids (CLAs) are a mixture of positional and geometric isomers of linoleic acid (LA) and believed to have many positive biological activities. The present study was undertaken to assess the antioxidant activity of cis-9, trans-11 and trans-10, cis-12 as single or mixed CLA isomers at two ratios, 1:6 and 1:13 (trans-10, cis-12/cis-9, trans-11). A microplate reader was used to determine the free radical scavenging properties of CLAs against DPPH radical in ethanol. The kinetic reactions of CLA-DPPH(•) showed that all tested CLAs have exerted radical scavenging activities in a dose-dependent manner and observed to immediately react and quench DPPH radicals at all tested levels and no lag phase was noticed in CLA-DPPH(•) reactions. The median inhibitory concentration (IC₅₀) value for cis-9, trans-11 CLA was observed to be more effective than other tested CLA. Total antioxidant capacity (TAC) of all tested CLAs were less effective radical scavengers as compared to vitamin E and butylated hydroxytoluene, although all tested CLAs were quenched a high amount (P < 0.05) of DPPH free radicals. All tested CLAs have the ability to directly react and quench DPPH free radicals in ethanol. Furthermore, trans-10, cis-12 CLA has greater maximal efficacy than other tested CLAs as free radical scavenger, while cis-9, trans-11 CLA is the most potent isomer to directly react and quench free radicals at low concentrations in the system, suggesting that the free radical scavenging activity of CLA isomers may contribute to their erse biological activities.
