Cardiovascular Diabetology , 2013, DOI: 10.1186/1475-2840-12-32
Abstract: Control or diabetic male Wistar rats (n=44) were randomly assigned to sedentary or trained groups. The training program consisted in a regular period of running on a treadmill during 8 weeks (10[degree sign] incline and up to 25 m/min, 60 min/day). The reactivity of isolated thoracic aorta rings of healthy, diabetic and/or trained has been tested.ACh and ADPbetaS-induced EDR were observed in phenylephrine (PE) pre-contracted vessels. As compared to sedentary control group, diabetic rats showed an increase in PE-induced contraction and a decrease in ACh and ADPbetaS-induced EDR (p<0.05). Moreover, there were no increase in ACh and ADPbetaS-induced EDR in diabetic rats. N-Nitro-L-Arginine Methyl Ester inhibited the nitric oxide synthase in diabetic and control rats, thereby resulting in a strong inhibition of the EDR induced by ACh and ADPbetaS (10-6 M).Diabetes induced an endothelium dysfunction. Nevertheless, our intense physical training was not effective to restore the aorta endothelial function.
Incidence of dog bite injuries and clinical rabies in a tertiary health care institution: A 10-year retrospective study
SA Abubakar, AG Bakari
Annals of African Medicine , 2012,
Abstract: Background: It is widely recognized that rabies is grossly under-reported even though it is a notifiable disease and a lack of accurate figures has rendered rabies a low public health and veterinary priority. This study aimed at determining the incidence of dog bite injuries and clinical rabies in a tertiary health care centre. Materials and Methods: Case records of patients managed at the accident and emergency unit of Ahmadu Bello University Teaching Hospital, Zaria, between June 2000 and May 2010 with diagnosis of dog bite and rabies were retrieved. Relevant clinical data were extracted using a structured questionnaire designed for the study. Results: Eighty-one persons out of 24,683 consultations in the accident and emergency unit presented with dog bite injuries with two clinical cases of human rabies. Mean age of victims of dog bite injuries was 21.1 ± 14.3 years and the majority (55.6%) were children. Males were more affected than females with a male:female ratio of 4.8:1, lower limb/buttock injuries were significantly higher in children than adults, but the adults sustained significantly more severe (type III) injury. The majority of dog bite injuries were washed with soap and irrigated with water or saline and 87.7% of the victim of dog bite received postexposure anti-rabies vaccine. Conclusion: Hospital incidence of dog bite injuries was low, but the use of postexposure prophylaxis was high.

AG Adkintomide, SA Oluwatosin
Edo Journal of Counselling , 2011,
Abstract: The study investigated the teacher characteristics that influence students’ choice of teaching as a career among secondary school students in Osun state, Nigeria. A sample size of 250 students was drawn from 10 randomly selected senior secondary schools in three local government areas of the state. Data were collected using a validated 35-item questionnaire titled “Teacher characteristics and students’ career aspiration”. The result revealed that factors such as quality of teaching, mode of dressing and communication skills are prominent among what students assess in their teachers as motivators towards choosing teaching as a career. The study also showed a significant relationship between students’ attitude to choice of teaching as a career and teachers characteristics (χ2 = 3.73, p < 0.05). There was also a significant difference between the attitude of private and public school students towards teaching as a profession with regards to teachers characteristics (t = 3.274, p < 0.05). The study concluded that with the prevalence of the observed problems, there is urgent need to work towards repositioning teaching as a career that would attract the interest of people with the potential to deliver the educational need of the Nation by addressing some of the teacher characteristics that can influence students’ choice of teaching as a career.

Bayero Journal of Pure and Applied Sciences , 2012,
Abstract: Field trials were carried out at the Teaching and Research farm of Kano University of Science and Technology Wudil with three pearl millet varieties in 2003, 2004 and 2005 rainy seasons to find out the reaction of cowpea intercropped with pearl millet infected with downy mildew on days to 50% heading and grain yield. The experiment was a 3 x 2 factorial in randomized blocks of six plots with three pearl millet varieties (LCIC 9702, Ex-Borno and Zango) and each variety was intercropped with a cowpea and planted sole making six treatments. Data collected on days to 50% heading and grain yield were subjected to T-test for the separation of means of sole and intercropped to bring out the differences between them at 1% and 5% levels of significance. Results showed that intercropped LCIC pearl millet variety had significantly (P≤0.05) more days to 50% heading than other varieties either planted sole or intercropped in 2004. Similarly, from the combined result, it showed that intercropped LCIC pearl millet variety had significantly (P≤0.05) more days to 50% heading than other varieties either solely planted or intercropped. Maximum grain yield was however obtained from sole Zango and intercropped LCIC 9702 pearl millet varieties. Combined result shows only intercropped LCIC 9702 had significantly (P≤0.05) maximum grain yield than other pearl millet varieties. It is imperative to grow sole LCIC 9702 pearl millet variety than intercropped with cowpea for less number of days to 50% heading. But for maximum grain yield, it is advisable to grow sole Zango and intercrop LCIC 9702 with cowpea.

Abstract: A seven month study (March-September 2006) on the prevalence of congenital malaria was carried out at the labour unit of three different hospitals within Ilorin metropolis: Eyitayo Hospital, Surulere Medical Hospital and Children Specialist Hospital Centre Gboro Ilorin. A total of 130 blood samples were collected from the mothers and their newborn babies and examined for malaria parasite using both thin and thick films. Maternal packed cell volume (PCV) and genotype was also determined using haematocrit method and cellulose acetate electrophoresis respectively. The prevalence rate of maternal, fetal, placental and cord parasitaemia were 37(28.46%), 29(22.31%), 33(25.38%) and 30(23.08%) respectively. Malaria infected maternal blood had a mild reduction in PCV level (p<0.05). Genotype showed strong correlation with maternal, fetal, placental and cord parasitaemia (p<0.05). However, the effect of malaria prophylaxis was shown to be more protective for the placental parasitaemia (p<0.05). Finally maternal age and parity did not show strong correlation with Maternal, fetal, placental and cord parasitaemia (p>0.05).

Revista Brasileira de Ciência Avícola , 2003,
Abstract: The present study investigated the chemical composition and metabolizable energy levels of ten meat and bone meals (MBM) produced in Minas Gerais state (Experiment I) and evaluated the growth performance of broilers fed with diets containing those MBM (Experiment II). In the first experiment, energy values (apparent metabolizable energy [AME] and corrected apparent metabolizable energy [AMEn]) of ten different MBM were determined using the traditional method with total collection of excreta. Four hundred forty 21 day-old Hubbard broilers were used. A reference corn and soybean meal-based diet was replaced in 20% by the feed containing MBM to be tested. A completely randomized experimental design was used with eleven treatments (one reference diet and ten MBM), four repetitions per treatment and 10 birds per repetition (5 males and 5 females). In the second experiment, five MBMs from the ten analyzed in Experiment 1 were used as phosphorus source and compared to a diet containing bicalcium phosphate. The growth performance of the broilers fed with these diets was analyzed, considering two ages of the onset of MBM inclusion in the diet (1 or 7 days of age). One-day-old Hubbard broilers (1,320 birds) were housed in 44 plots with 30 birds per experimental unit. The experiment consisted of 11 treatments in a 5x2 factorial arrangement, with five sources of MBM, two ages for the onset of inclusion, and a reference treatment without addition of MBM. The results obtained showed a great variation in the chemical composition and apparent metabolizable energy of the evaluated meals. No significant differences were found on the performance of broilers fed diets with different MBM or the diet with bicalcium phosphate as phosphorus source. The performance of broilers was not significantly influenced by the onset of MBM inclusion in the diets.

Alexandria Journal of Medicine , 2012,
Abstract: Background: This study was designed to evaluate the effect of intravenous dexmedetomidine infusion in patients undergoing major abdominal surgery on stress response markers as plasma interleukin-6, cortisol and blood glucose level. It also assessed its effect on recovery profile and postoperative pain. Methods: Thirty adult ASA I–III patients admitted to the surgery department of the Alexandria Main University Hospital scheduled for elective major abdominal surgery under general anaesthesia were included. They were randomly classified into two equal groups of 15 patients each, dexmedetomidine group (Group D) received intravenous dexmedetomidine infusion and placebo group (Group P) received intravenous infusion of normal saline. Haemodynamic parameters were recorded intra- and postoperatively. Interleukin-6, cortisol and blood glucose levels were measured. Recovery profile, postoperative pain score and analgesic requirement postoperatively were assessed. Results: Heart rate and mean arterial pressure were significantly lower in group D relative to group P during most of the intra- and postoperative periods. Postoperatively, the levels of interleukin-6, cortisol and blood glucose were significantly lower in group D relative to group P. Recovery time was longer in group D than group P but with no significant difference. Postoperative pain score was significantly less in group D relative to group P during the early postoperative period with smaller amount of analgesic requirements in group D. Conclusion: Dexmedetomidine is safe and effective in blunting the postoperative rise of the proinflammatory cytokine interleukin-6 and resulted in lower levels of markers of stress response to surgery as cortisol and blood glucose. Dexmedetomidine also reduces the postoperative pain score without delaying recovery from anaesthesia.

Abstract: Cigarette smoking is a major public health problem that is associated with high morbidity and mortality. This study was designed to investigate the relationship between cigarette smoking and concentration of testosterone in the urine. Forty young men age between 23 to 31 years were used for this study. The subjects were divided into two groups of 20 controls (noncigarette smoker) and 20 experimental groups (cigarette smoker). 5ml of mid-stream urine was collected from each subject at 0700 hour and urine testosterone concentration was estimated using enzyme immunoassay method. The result showed that the urinary testosterone concentration of non-cigarette smokers was 4.35±0.52 ng/ml, while the concentration in cigarette smokers was 2.81±0.38 ng/ml with p<0.01. It is concluded that cigarette smoking reduced urinary testosterone concentration among cigarette smokers.
