Adhatoda vasica (L.) (Acanthaceae) is used in the indigenous system of medicine in India. The alkaloid Vasicine was isolated from ethanolic extract of the leaves of A. vasica using column chromatography. Vasicine acetate was obtained by acetylation of Vasicine. Vasicine acetate exhibited good zone of inhibition against bacteria: 10 mm against E. aerogenes, 10 mm against S. epidermidis, and 10 m...

A 280-d study examined the effects of 17β-estradiol (E2) on reproduction and development of the sheepshead minnow (Cyprinodon variegatus) exposed from the parental (F0) through three subsequent (F1, F2, and F3) generations and evaluated the need for multigenerational assessments of the risks of endocrine-disrupting chemicals. This first three-generation study exposed adult F0 and F1 fish to mea...

Geometric mean blood lead was 120 μg/L (95% CI: 115 -125), with a higher concentration in men than in women (127 vs 114 μg/L, p=0.01). Sixty-three percent of children aged less than 6 years old presented blood lead levels above the 100 μg threshold. In the adult population, occupations with a potential risk of exposure to gasoline (car mechanics or garage owners, taxi drivers, conveyors and gas...

Objectives: In artisanal small-scale gold mining (ASGM) areas in many developing countries, mercury (Hg) is used to extract gold from ore. Data of 1250 participants from Indonesia, Mongolia, Philippines, Tanzania, and Zimbabwe were combined to analyze the relation between exposure in ASGM areas and body burden. Methods: Four groups were selected relating to their intensity of contact with mercu...

The aim of this study was to assess the effects of Cyperkill 25 EC (a.i. cypermethrin 250 g/l) on cumulative mortality, growth indices, and ontogenetic development of embryos and larvae of common carp (Cyprinus carpio L.). An early-life stage toxicity test was used. Liver, intestine, kidneys, and gills of surviving larvae were examined, and the activity of the detoxifying and antioxidative enzy...

ferritin is a macromolecule and is responsible for the long term iron storage function in human serum and plasma. recent studies have highlighted the role of cell phone exposure on central nervous system, immune function and reproduction. the aim of this study was to investigate whether the human serum ferritin level could be interfered by the exposure to the 900 mhz gsm cell phones. fifty huma...

In 2005 the United States Environmental Protection Agency registered spinosad as a grain protectant at 1 μg(AI)/g. The effectiveness of spinosad at 1 μg(AI)/g against many beetle and moth pests of stored grains is well established. In recent years, several psocid species have emerged as economically important pests in various stored-product environments in many countries, including the United S...

mercury is among the most toxic nonradioactive elements which may cause toxicity even at low doses. some studies showed release of mercury from dental amalgam fillings in individuals who used mobile phone. this study was conducted to assess the effect of high-field mri on mercury release from dental amalgam filling. we studied two groups of students with identical tooth decays requiring a simil...
