in the present study, interactions between lead exposure with nitric oxide precursor (l-arginine) or nitric oxide synthase (nos) inhibitor (l-name) on naloxone-induced jumping and diarrhea in morphine-dependent mice were examined. chronic lead acetate (0.05%) exposure altered naloxone-induced jumping and diarrhea in mice. jumping was decreased after 7 days and was unchanged 14 and 28 days after...

Airway nitric oxide production is decreased in cystic fibrosis. As growth hormone therapy has been shown to increase nitric oxide production in growth hormone-deficient patients, it may also affect nitric oxide production in patients with cystic fibrosis. The objective of the present study was to investigate the effect of growth hormone therapy on systemic and airway nitric oxide formation in p...

the present study provides the data on the population parameters of an endemic qanat spirlin, alburnoides qanati from the endorheic kor river basin of iran to assess the stock status of this cyprinid fish species, which is highly important from management and conservation points of views. fish specimens (387) were collected from moshkan stream, kor river basin, iran in 2011-2012. asymptotic len...

In comparison to other pseudomonads, Pseudomonas aeruginosa grows poorly in L-lysine as a sole source of nutrient. In this study, the ldcA gene (lysine decarboxylase A; PA1818), previously identified as a member of the ArgR regulon of L-arginine metabolism, was found essential for L-lysine catabolism in this organism. LdcA was purified to homogeneity from a recombinant strain of Escherichia col...

Lysine caused a greater depression in growth of chicks fed a diet con taining casein than a diet containing a combination of safflower meal, corn gluten meal and soybean meal. Clycine, in the presence of arginine, appeared to exhibit a synergistic effect in alleviating the growth depression induced by an excess of lysine. Similarly, glycine supplementation decreased nitrogen retention in a diet...
