The major objective of the present study was to identify the relationship of physiologial parameters of the photosynthetic system with the elemental content of the lichen Ramalina lacera (With.) J.R. Laund. Thalli of R. lacera were collected in an unpolluted site and transplanted in a national park and an industrial region in Israel for 8 mo. Analyses of photosynthetic activity, chlorophyll int...

High doses of ZnO are used to treat diarrhea in weaning pigs but are also an environmental concern. The mechanism of action of Zn against diarrhea is still not well understood. The amount of solubilized Zn, the relation of Zn with Fe and Cu, and the concentration of these elements in the gastrointestinal tract (GIT) are key data to understanding its mechanism of action and optimize its use. The...

An in vitro experiment was conducted to evaluate the effect of different dietary minerals on phytate hydrolysis by microbial phytase enzyme and to measure the residual phytate content after phytate digestion. Calcium (0, 6, 8, 10 g kg of diet), Fe (0, 70, 80, 90 mg kg of diet), Zn (0, 30, 40, 50 mg kg of diet) or Na (0, 1.5, 2.5 and 3.5 g kg of diet) were incubated with a Na-phytate solution, w...

in the paper, the contents of calcium (ca), magnesium (mg), zinc (zn), copper (cu), iron (fe),manganese (mn), chromium (cr), lead (pb), cadmium (cd), aluminium (al), and nickel (ni) were determinedin the meat of roe deers, wild boars, and hares coming from central region of poland. measurements werecarried out using atomic absorption spectrometry. the ranges of median values found for the conce...

Cement dust deposition on soil has been implicated in the heavy metal (HM) contamination of soil, leading to adverse effects on plants and humans. This study assessed the impact of cement dust deposition on the HM content of the soil samples in the vicinity of a cement factory and its implication on the public health of the host community. Topsoil samples were collected at varying distances and...

agronomic and physiological traits and protein expression were compared between non-bt glandless upland cotton variety-zhong5629 and its bt-transgenic near-isogenic lines differing in cryiac gene. results showed that the bt isogenic line had higher plant height and rate of effective bolls, more internal bolls but lower yield, than the non-bt line. the bt isogenic line had lower chlorophyll cont...
