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...

The physiological properties of canavanine, a naturally occurring, structural analogue of arginine, have not been extensively investigated. Recently, Horowitz and Srb (1) found that canavanine inhibited growth of wild type Neurospora, and that the inhibition was competitively alleviated by arginine. Lysine and methionine were also effective in alleviating canavanine inhibition for certain strai...

Cationic amino acid transporters (mCAT1 and mCAT2B) regulate the arginine availability in macrophages. How in the infected cell a pathogen can alter the arginine metabolism of the host remains to be understood. We reveal here a novel mechanism by which Salmonella exploit mCAT1 and mCAT2B to acquire host arginine towards its own intracellular growth within antigen presenting cells. We demonstrat...

objective: the aim of this experiment was to determine chemical composition, protein quality of corn gluten meal (cgm) and its effect on growth performance of broiler chicks. methods: chemical composition and nitrogen corrected true metabolizable energy of cgm was determined by standard and precision-fed cockerel assay methods.  for evaluating of protein quality, 90 male broiler chicks in a com...

African marigold (Tagetes erecta L.) is one of the most well-known ornamental, medicinal and edible flowers in world. A factorial experiment based on completely randomized design with 20 treatments 3 replications, 60 plots 5 plants per plot were conducted order to investigate effect amino acids growth, nutritional parameters antioxidant capacity marigold. Experimental included two cultivars (‘Y...

In Oscillatoria chalybea, as in other cyanobacteria, nitrate reduction depends directly on photosynthetic activity. Hence, nitrate reduction occurs only in the light and appears inhibited when photosynthesis is inhibited by the herbicide DCM U. Growth o f Oscillatoria cells is pos­ sible on a variety o f exogenous nitrogen sources in the medium and appears largely independ­ ent on the type of n...

Streptococcus pneumoniae (pneumococcus) is a major human pathogen causing pneumonia, sepsis and bacterial meningitis. Using a clinical phenotype based approach with bacterial whole-genome sequencing we identified pneumococcal arginine biosynthesis genes to be associated with outcome in patients with pneumococcal meningitis. Pneumococci harboring these genes show increased growth in human blood ...

BACKGROUND Transforming growth factor-beta(1) (TGF-beta(1)) contributes to arterial remodeling by stimulating vascular smooth muscle cell (VSMC) growth and collagen synthesis at sites of vascular injury. Because L-arginine is metabolized to growth-stimulatory polyamines and to the essential collagen precursor L-proline, we examined whether TGF-beta(1) regulates the transcellular transport and m...
