Application of acid-hydrolyzed cassava (Manihot esculenta) and cowpea (Vigna unguiculata) for the production of yeast (Saccharomyces cerevisiae)
Much progress has been made in the cultivation and production of cassava (Manihot esculenta) and cowpea (Vigna unguiculata) in Nigeria. In the present study, investigation was carried out on the possibility of using cassava flour as a source of glucose as well as cowpea as source of nitrogen in the production of yeast. Acid hydrolysis (using dilute H2SO4) of cassava and cowpea was undertaken to release the sugars and...

Captopril interferes with some serum biochemical findings
Captopril is a widely used anti-hypertensive drug that acts by inhibiting angiotensin-converting enzyme. This work has been carried out to investigate the effects of captopril on some common biochemical laboratory parametres in the sera of patients receiving the drug. For this study, 40 subjects were included, all within the age range of 40 to 63 years and with newly diagnosed essential hypertension. From each patient,...

Effect of ferric oxide nanoparticles on microtubules organization
Nanoparticles (NPs) are widely used in several manufactured products. The small size of nanoparticles facilitates their uptake into cells as well as transcytosis across epithelial cells into blood and lymph circulation to reach different sites, such as the central nervous system. Studies have shown different risks of Fe2O3NPs in the neuronal system and other organs. They are membrane-bound layer aggregates or...

Synergistic effects of glucan and resveratrol
Recent data showing that glucan stimulates defense reactions in plants through synthesis of resveratrol, led us to study the possible synergetic effects of a glucan-resveratrol complex on immune reactions in mice. We measured phagocytic activity, expression of CD4 marker on spleen cells, IL-2 secretion and antibody response. In all cases we confirmed the stimulatory effects of glucan. Resveratrol alone had either limit...

Assessing the role of RecA protein in the radioresistant bacterium, Deinococcus geothermalis
The moderately thermophilic bacterium Deinococcus geothermalis exhibits extraordinary resistance to ionizing radiation. RecA protein is considered to be one of the most important participants in radioresistance. To assess the role of the RecA protein in D. geothermalis, the recA gene was isolated from D. geothermalisand over expressed in Escherichia coli. After the D. geothermalis RecA...
