Zinc has previously been reported to alleviate salinity stress in plants. In this study, we monitored various biomass and chlorophyll fluorescence parameters to determine the optimum zinc sulfate concentration that can be used as foliar spray to alleviate salinity stress in Glycine soja. The plants subjected to a series of salinity levels (NaCl concentration of 0, 100, 200, and 300 mmol L), app...

Streptomyces griseus was cultured in three different bioreactors in a medium containing chitin flakes. When a conventional bioreactor stirred by two sets of Rushton impellers and operated at high speed was used, the yield of streptomycin (3.1mg/l) was the highest observed and occurred at approximately 500 h. Cultivation of S. griseus in a bioreactor stirred at low speed by a U-shaped paddle res...

Aim and objectives: Lead is one of the most important environmental pollutants that plays a significant role in increasing the stability of some other pollutants through changing the microbial profile of soil.  Bacillus subtilis WPI is one of the most abundant bacteria existing in the wastewater. Due to the presence of laccase enzyme in this bacterium, it can facilitate the decomposition proces...

Vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and transforming growth factor-beta(1) (TGF-beta(1)) mRNA increase in rat skeletal muscle in response to a single acute exercise bout. Nitric oxide (NO) is released locally by muscle vascular endothelium and muscle fibers during exercise, contributes to the blood flow response to exercise, and regulates mitochondr...

Mycobacterium tuberculosis is a concern in patients with human immunodeficiency virus (HIV) infection. Rifampin (RIF), an agent used against M. tuberculosis, is contraindicated with most HIV protease inhibitors. Atazanavir (ATV) has clinical efficacy comparable to a standard of care regimen in naive patients and, when dosed with low-dose ritonavir (RTV), also in treatment-experienced patients. ...

The methanolic extract of leaves of Turnera ulmifolia L was evaluated for its effect on blood glucose in alloxan-induced diabetic and euglycemic rats. The extract were administered at three doses of 100, 200 and 400 mg/kg, p.o. Glibenclamide (10 mg/kg, p.o.) was used as standard for control group. In euglycemic rat, extract were administered at three doses of 100, 200 and 400 mg/kg, p.o. Extr...

wheat crop, considering its high planting area and consumption at national scale, demand a regular yield increase. humic acid, as an organic acid obtained from humus and organic sources without any environmental destructive effects, improves wheat yield particularly in variable environment conditions. in order to evaluate the effects of different levels of humic acid on shoot and wheat yield, a...

2-n-Butyl-3-(4'-diethylaminoethoxy-3',5'-diiodobenzoyl)-benzofurane (amiodarone), a drug used in arrythmias and angina pectoris, contains 75 mg of organic iodine/200 mg active substance. Four studies were performed to test its effect on thyroid hormone metabolism: (a) nine male subjects were treated with 400 mg of amiodarone for 28 days; (b) five male subjects received, for the same period of t...
