In order to investigate the effect of humic acid (HA) and nano-calcium chelate on the cut flowers of gerbera cv. Dune, an experiment was performed as a completely randomized design with two factors and three replications in hydroponic conditions. The first factor included humic acid at 4 concentrations of 0 (control), 500, 1000, and 2000 mg L-1 as drench and the second factor was ass...

To evaluate the efficacy of green tea polyphenols (GTPs) in modulating aflatoxin B(1) (AFB(1)) biomarkers, a total of 352 serum samples and 352 urine samples collected from a 3 month chemoprevention trial with 500 mg GTPs, 1000 mg GTPs and a placebo were measured for AFB(1)-albumin adducts (AFB-AA), aflatoxin M(1) (AFM(1)) and aflatoxin B(1)-mercapturic acid (AFB-NAC). Levels of AFB-AA at basel...

picralima nitida is used traditionally for management of cough. this study, therefore, investigated the antitussive, expectorant, and analgesic properties of the ethanolic seed extract of picralima nitida (pne), and ascertained its safety for use. presence of secondary metabolites, and safety of pne (10-2000 mg/kg) were evaluated by preliminary phytochemical screening, and by irwin’s test respe...

anethum graveolens l. (dill) is used widely in asian food and folk medicine but its safety profile for further clinical studies has remained unclear. after administration of total hydroalcoholic extract to mice in acute, subacute and subchronic treatment periods, toxic responses were recoreded by clinical, biochemical, hematological and pathological examinations. doses up to 2000 mg/kg in acute...

Thallium (Tl) is a highly volatile and toxic heavy metal regarded to cause pollution even at very low concentrations of several parts per million. Despite the extremely high risk of Tl in the environment, limited information on removal/recovery exists. The study focussed on the use of green algae to determine the sorption potential and recovery of Tl. From the study, removal efficiency was achi...
