Sulfur is an essential mineral in human nutrition, involved vital biochemical processes. deficient soil becoming a severe issue, resulting from increased agricultural production and decreased sulfur emissions. Tomato cultivation using sulfur-poor soils desalinated water widespread, might result plant fruit deficiency. In the current work, we aimed at evaluating effect of fertilization (0.1–4 mM...

The objective of this study is re-evaluation the long-term record limnological parameters in Lake Kinneret (1970–2018) and its drainage basin (1940–2018) aimed at an indication possible impact climate change on water quality Kinneret. methodological approach based significant changes, temperature increase, decline rainfall, causing a reduction river discharges, lake inflows. These climatologica...

We developed a new technique that monitors metabolic competency in female heterozygotes for ornithine transcarbamylase deficiency (OTCD). The method uses mass spectrometry to measure conversion of (15)NH4Cl to [15N]urea and [5-(15)N]glutamine following an oral load of (15)NH4Cl. We found that heterozygotes converted significantly less NH3 nitrogen to urea, with this difference being particularl...

Exposure to stressful stimuli causes activation of the hypothalamic-pituitary-adrenal axis which rapidly releases high concentrations of glucocorticoid stress hormones, resulting in increased cellular metabolism and spontaneous oxygen and nitrogen radical formation. High concentrations of nitrogen radicals, including nitric oxide, cause damage to cellular proteins in addition to inhibiting comp...

Nitric oxide (nitrogen monoxide; NO) is a simple molecule with diverse biological functions. NO and related reactive nitrogen oxide species (RNOS) mediate intricate physiological and pathophysiological effects in the central nervous system. Depending on environmental conditions, NO and RNOS can initiate and mediate neuroprotection or neurotoxicity either exclusively or synergistically with othe...
