An evaluation of antioxidants and oxidative stress in Iraqi patients with thyroid gland dysfunction
The present study evaluates the effects of hypothyroidism and hyperthyroidism states on antioxidant vitamins (A, E, C, β-carotene) and uric acid in Iraqi patients before treatment. Lipid peroxidation, an index of oxidative stress was elevated in hyperthyroidism but reduced in hypothyroidism patients as compared to control. The results showed a highly significant decrease in the sera levels of Vitamins A, E...

Angiotensin-converting enzyme genotypes relationship with blood pressure, C-reactive protein and selected physical tests in Zulu South African cricketers
Zulu cricketers (n=14) and students (n=17) as controls were genotyped (blood spots) for angiotensin converting enzyme (ACE), gene by PCR amplification followed by agarose gel electrophoresis. Systolic and diastolic blood pressure (SBP and DBP) and grip strength (kg), knee extension and flexion (Nm/kg) were measured, systolic tension time (STT) and metabolic rates (MR) were calculated. After ANOVA, the association...

Altered protease activity due to heat shock in the whole organism Bombyx mori L.
The domesticated insect Bombyx mori respond well to environmental fluctuations that govern the success of cocoon production due to its piokilothermic nature. Since, the interaction between heat shock proteins and proteases in the whole organism that complete larval life in natural environment remain obscure, we have employed zymography technique to examine different classes of proteases and its activity under...

Anti-plasmodial activity of aqueous root extract of Acacia nilotica
Acacia nilotica, of family Fabaceae, is a thorny tree commonly used in Northern Nigeria for the treatment of cough, diabetes and malaria. Aqueous root extract of A. nilotica was analyzed for antiplasmodial activity in mice. Acute toxicity of the extract was studied using Organization for Economic Cooperation and Development (OECD) guideline 423. Suppressive activity, curative and prophylactic effect...

Evaluation of different matrices for production of alkaline protease from Bacillus subtilis –K 30 by entrapment technique
The present investigation evaluates the suitability of different matrices such as calcium alginate, polyacrylamide, agar-agar and gelatin for production of alkaline protease from Bacillus subtilis-K 30 using immobilization approach. Calcium alginate was found to be an effective and suitable matrix for higher alkaline protease productivity compared to other matrices studied. All the matrices were selected for...
