The interaction of HIV and tuberculosis
Tuberculosis (TB) is frequently observed in HIV-infected patients living in sub-Saharan Africa. HIV-TB co-infection poses many problems with regard to diagnosis, treatment, drug resistance, and burdens on the health systems of developing African countries. The aetiological agent of TB, Mycobacterium tuberculosis, interacts with HIV through a number of mechanisms that support disease...

Studies on the isolation of normal and abnormal seedlings of Chrysophyllum albidum: A step towards sustainable management of the taxon in the 21st century
The authors’ field trip revealed that the local populace attempted to plantChrysophyllum albidum seeds but met with severe limitation. In the light of the above a study was designed to determine the optimum seed germination medium, normality and abnormality of seedlings. Of all the growth media used, 4 parts topsoil (4PTS) + 4 parts farm yard manure (4PFYM) had the best result. A mean seed...

Comparison of the efficacy of magnesium sulphate and diazepam in the control of tetanus spasms
Tetanus though preventable through vaccination, it continues to be a major scourge and a common cause of death in developing countries. The objective of this study is to compare the efficacy of magnesium sulphate and diazepam in controlling the tetanus spasm. This was a randomized double blind controlled trial. A total of 42 patients with clinical diagnosis of tetanus, received continuous infusion of either...

Genetic structure of rice samples from a germplasm bank
The analysis of genetic relationships in crop species is an important component of crop improvement programs, as it serves to provide information about genetic diversity. Accurate assessment of levels and patterns of genetic diversity can be invaluable in crop breeding for diverse applications such as analysis of genetic variability in cultivars, identifying diverse parental combinations to create segregating...

Cobalt reverses vanadate inhibition of rat kidney alkaline phosphatase
Vanadate ion (VO43-) is an established inhibitor of alkaline phosphatase (ALP) and inorganic phosphate transport across biologic membranes. The concentration-dependent effects of Co2+ and VO43- on rat kidney ALP activity were carried out over a range of 3.33 – 25.67 mM p–NPP concentrations. The investigation revealed Co2+ as an activator of rat kidney ALP, while vanadate inhibited...

Evaluation of microbial hazards associated with the processing of Suya (a grilled meat product)
Suya is a popular spicy roasted meat product in Nigeria. Ready-to-eat Suya samples were collected from six 'Suya spots' serving at least 240 consumers in 6 selected cities within south-western Nigeria. On-line process monitoring and sampling during processing was used to identify the Critical Control Points and evaluate microbiological hazards. Microbiological analyses of 144 samples ofSuya,...
