SS Ngulukun, SI Oboegbulem, IO Fagbamila, W Bertu, MO Odugbo
Nigerian Veterinary Journal , 2011,
Abstract: A study was designed to determine the prevalence of Campylobacter species isolated from cattle in Plateau state, Nigeria. From April, 2008 – March, 2009, 352 rectal swab samples were randomly taken from cattle in 18 herds in Plateau State, Nigeria and analyzed for the presence of Campylobacter species. Out of the 352 samples tested, 65 (18.5%) were identified as Campylobacter species using biochemical tests; with 52 (80%) as C. jejuni and 13 (20%) as C. coli. Of the 65 isolates, 63 (97%) were confirmed by polymerase chain reaction (PCR). Out of the 18 cattle herds tested, 12 (66.7%) were positive. The results of the study also showed that the prevalence was significantly (p<0.05) higher in calves (25%) than in adults (12.2%).

Nigerian Veterinary Journal , 2010,
Abstract: Importation of exotic cattle to improve the yield and productivity of the local 'White Fulani' breed of cattle has been on the rise in Nigeria. The problem most farmers faces with the Friesian has always been the adaptation to the weather and endemic disease conditions in Nigeria. Fungal infections represent an important complication for immunosuppressed animals and are associated with high morbidity and mortality (De Pauw and Meunier, 1999). Fusarium is one of the most important fungal genera, which includes many species that are pathogenic to plants and responsible for a broad range of diseases while others are highly mycotoxigenic (Viquez et al., ) and some cause opportunistic infections in humans and in farm animals. Fusarium graminearum (Gibberella zeae) is an important pathogen of commercial crops such as wheat, maize, and rice. Infection with F. graminearum causes yield losses in grains and degrades their nutritive, physical and chemical qualities, resulting in their being used for animal feed rather than for human consumption (Charmley et al., 1994). A contaminated crop can be salvaged by feeding it to livestock or poultry, but further losses may be incurred due to the negative effects of mycotoxins on animal performance. Potent toxins such as the estrogenic toxin zearalenone (F-2) have been reported by Vesonder and Hesseltine, (1980) but the most common mycotoxins produced by F. graminearum are deoxynivalenol (DON, also known as vomitoxin), 15-acetyldeoxynivalenol, and nivalenol belonging to a group of compounds known as trichothecenes (Homdork et al., 2000; Council for Agricultural Science and Technology, CAST, 2003). These mycotoxins are known to diminish feed consumption in domestic livestock, especially swine (CAST 2003). Because of their apparent tolerance for higher levels of dietary DON, Fusarium-infested grains are often fed to cattle or sheep as opportunity feeds. This may be due to little or insufficient information describing the pathogenesis and the ability of this plant pathogen to survive as they move through the gastrointestinal tract of cattle or on a compromised skin (Kedar and Gemerlyn, 2008).
Integrating the Internet with the Curriculum of Office Education Programme in Tertiary Institutions in Nigeria
SS Amoor
Information Manager (The) , 2008,
Abstract: The Internet is one of the latest technological breakthroughs in the history of Information and Communication Technology (ICT). Many government establishments, parastatals and private organizations use it for business transactions. Consequently, these organizations demand secretaries that are very knowledgeable and versatile in the use of Internet. Unfortunately, many secretaries do not possess Internet skills. The paper looks at the role of the Internet in office education programme and the justification to integrate the Internet studies into the curriculum of office education programme at the tertiary institutions so as to expose the secretarial students to the knowledge and competencies of the Internet in the school environment before they face the world of work. It recommends among others the Internet courses to be integrated into the curriculum of Secretarial Education programme that will make secretarial graduates very relevant to the labour market.
Pre-natal effects of ethanol and folic acid supplements on the mineralisation of bones in Wistar rat
SS Adebisi
Annals of African Medicine , 2003,
Abstract: Background: Alcohol consumption has long been implicated as capable of inducing folic acid deficiency, in particular at pregnancy; thus inflicting severe skeletal dysgenesis on the conceptuses particularly the mineralisation of the bones. Methods: In the present study, 120 adult female Wistar rats were grouped into three: A, B and C. Group A received 0.79g/kg of 30% ethanol from day 1 to day 10 of gestation, group rats received same dosage of ethanol plus 0.14g/kg folic acid supplements for the same period, and group C served as the control. Bone calcium and phosphorus contents were assessed daily from day 12 to 21 in the conceptuses of the three groups; and also the detailed sequence of calcification in the foetal bones were simultaneously monitored with alizarin red S stains. Results: Low mineral levels and a lag or delay in calcification of about 2 days were recorded in the ethanol rats compare with the folate supplement group; with respect to the control, reparative or ‘catch-up' growth was displayed in the ethanol plus folate treated rats. Conclusion: These observations attest to the toxic consequences of gestational ingestion of ethanol on bone, and the possible alleviating effects of folic acid supplementation.
Sex identification from the skull of the Hausa/Fulani in northern Nigeria
SS Adebisi
Annals of African Medicine , 2003,
Abstract: Background: The Hausa / Fulani is one of the major races in Nigeria, with scanty craniometrical records for sex identification, a useful resource in forensic study and anthropometry. Methods:Craniometry of non-pathologic radiographs of the skull was done to evaluate the sexually dimorphic characteristics in the bones. Results: Statistical analysis of the figures revealed significant higher dimensions in the male over the female in the parameters considered except in the nasal height and orbital bones; sex discrimination was also illustrated in the craniometrical indices except in the nasal bone. Possible factors responsible for these observations were discussed. Conclusion: It is suggestive that the findings could possibly serve as indicator of sex identification in this race.
Teaching and Teacher Education for Health Professionals: Perspectives on Quality and Outlook of Health Professionals Education in Zambia
SS Banda
Medical Journal of Zambia , 2008,
Abstract: Purpos: To measure students’ perspectives on the teaching quality of the school of medicine at University of Zambia and concurrently measure health professionals educators perspectives on the need for teaching courses for health professionals educators (educational skills training). The results are discussed as indications for educational skills training for educators in health professionals’ education. Method: 250 medical students from the MB ChB programme were surveyed, in an evaluation exercise, to rate the teaching contribution of all the full-time and honorary lecturers (n=88). The students were requested to rate each lecturer out of 10 on eight scales: a) attendance, b) punctuality, c) clarity, d) interest in the subject, e) supportiveness to students, f) ability as a lecturer, g) appropriate use of audiovisual aids, and h) amount of workload done in the academic year. Additionally, a multi-site study surveyed 426 health professionals educators, defined as persons who considered themselves as continually participating in teaching students in a training institutions for health professions in the Country on the necessity for and their willingness to enroll into a teaching programme for health educators. Results: Two hundred students of the eligible 250 completed the evaluation giving a response rate of 80%. The scores for teaching quality ranged from 8/ 40 to 40/40. The mean score was 32.2. The results showed that about 27.2% (n=24) did not meet the merit standard which was set at 30/40 as the quality assurance benchmark by the School. This result suggests that a large proportion of teaching staff could benefit from teacher education. Four hundred and four questionnaires were completed and returned out of the 426 that had been distributed, yielding a response rate of 94.8 %. The Cronbach’s alpha for reliability test was 0.62 – 0.70 on the teaching skills sub-scale and 0.76 – 0.78 on the Educational skills sub-scale. The majority, over 85%, acknowledged they lacked expertise in educational skills and that they would enrol in a programme to improve their educational skills. There was overwhelming (>90%) agreement in topics to be covered. Limitations: Quality of teaching contributions only measured at school of medicine; Large proportion of educators’ survey were not full-time teaching staff. Implications: The belief that professional qualifications are sufficient for preparation for teaching health professionals is now being confronted. Formal systems of teacher education in the health professions have emerged worldwide and are now also available in Zambia.
An empirical study on impact of index futures trading on spot market in india
SS Debasish
KCA Journal of Business Management , 2009,
Abstract: In this paper, an attempt is made to investigate the effect of futures trading on the volatility and operating efficiency of the underlying Indian stock market by taking a sample of selected individual stocks. Specifically, the study examines whether the index futures trading in India has caused a significant change in spot price volatility of the underlying stocks and how the index futures trading has affected market/trading efficiency in the Indian futures and stock markets. The effect of the introduction of futures trading is examined using an extended period of June 1995 to May 2009.We employ an event study approach to test whether the introduction of index futures trading has resulted in significant change in volatility and efficiency of the stock returns. The study compares spot price volatility changes before and after futures trading is introduced in the stock indices. The result shows that the introduction of Nifty index futures trading in India is associated with both reduction in spot price volatility and reduced trading efficiency in the underlying stock market. The results of this study suggest that there is a trade-off between gains and costs associated with the introduction of derivatives trading at least on a short-term perspective. This paper offers a unique contribution in examining the impact of introduction of index futures trading in NSE Nifty index and the index futures covering a period since introduction of index futures in Indian Capital Market. The results suggest that the market would have to pay a certain price, such as a loss of market efficiency for the sake of market stabilization. Hence, a desirable market policy for derivatives trading would be one that would preserve market stabilization while still not damaging market efficiency in the underlying spot market. Key Words: Futures, Financial Engineering, NSE Nifty, Event study, Market Efficiency.
Foetal alcohol syndrome: an osteometric evaluation in the wistar rat animal model
SS Adebisi
Nigerian Journal of Surgical Research , 2003,
Abstract: Background: Foetal alcohol syndrome had been reported as a common feature in the off – springs of alcoholic mothers; and craniofacial and limb bones anomalies are usually some of the cardinal features of foetal alcohol syndrome (FAS). Methods: These features were osteometrically assessed in the cranial and limb bones of the harvested foetuses of pregnant Wistar rats' models. Results: Mal-developments and stunted growth with no evidence of post treatment reparation or recovery were observed in the ethanol – treated rats. Conclusion: This observation is possibly indicative of another dimension at improving our understanding of the mechanism of the toxicity of ethanol. Key Words: Foetal alcohol syndrome, bone anomaly, osteometry, wistar rat Nigerian Journal of Surgical Research Vol.5(1&2) 2003: 160-165
Review Article: The Role of Nitric Oxide Synthase in Post-Operative Hyperglycaemia
SS Qader
Libyan Journal of Medicine , 2008,
Abstract: Post-operative hyperglycaemia is important with regard to outcomes of surgical operations. It affects post-operative morbidity, length of hospital stay, and mortality. Poor peri-operative blood glucose control leads to a higher risk of post-operative complication. Insulin resistance as a cause of postoperative hyperglycaemia has been blamed for some time. Nitric Oxide (NO) is produced by nitric oxide synthase (NOS) isoenzymes. Inducible nitric oxide synthase (iNOS) is not a normal cellular constitute. It is expressed by cytokines and non-cytokines e.g. fasting, trauma, intravenous glucose, and lipid infusion, which are encountered in surgical operations. Review of current published data on postoperative hyperglycaemia was completed. Our studies and others were explored for the possible role of NO in this scenario. Induction and expression of iNOS enzyme in pancreatic islet cells is included in the chaotic postoperative blood glucose control. The high concentrations of iNOS derived NO are toxic to pancreatic β-cells and may inhibit insulin secretion postoperatively. Hence, current peri-operative management is questionable regarding post-operative hyperglycaemia and necessitates development of a new strategy.
Alcohol effects on embryonal bone growth
SS Adebisi
Nigerian Journal of Surgical Research , 2005,
Abstract: Background:The possible teratogenic and lethal potencies of ethanol on the developing foetal bones especially when ingested during pregnancy is now well established; but the actual mechanisms of these actions are yet elusive and this had since stimulated unending interests and numerous researches particularly in the field of teratology. Are there yet any other possible mediators / agents to be implicated in the potentiation of ethanol toxicity? Are they existing or would there be possible solutions for assaults of alcohol abuse? Methods: A retrospective and contemporary literature compilation was done in an attempt to further explore this subject and bring out more detailed information useful to answering these and other such lingering questions. Results: The incidence of congenital bone malformations associated with maternal consumption of ethanol during conception are now recognised to be due to its toxic effects on the developing tissues and impairment of normal cellular activities particularly by depriving them of essential vitamins such as folic acid, a useful precursor for the synthesis of proteins and DNA. Conclusion: This is a situation where the most successful preventive measures could possibly be instituted, with folic acid supplementation, to alleviate ethanol toxicity, if total abstinence is not possible.
