The accumulation of proline impacts the defense mechanisms plants against harmful effects adverse environmental conditions; however, its concentration in is associated with metabolism N. Therefore, exogenous organic [glutamate (Glu)/arginine (Arg)] and inorganic [nitrate (NO3−)/ammonium (NH4+)] N on (Pro) rice under trivalent chromium [Cr(III)] stress were studied through using mass balance mat...

Pistachio is one of the most important horticultural crops in Iran.  There is a unique role for amino acids in the plant response to stressful conditions, and special physiological role for Arginine (Arg) compared to other amino acids.  The effects of this compound were investigated on vegetative and reproductive characters of bearing pistachio trees of ‘Ahmad-Aghaei’. The experiments were done...

This experiment was conducted to evaluate the effects of supplemental L-arginine (ARG) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. A total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. Treatment groups were designed as a normal-prote...

Background: The p53 tumor suppressor gene plays important roles in genomic stability. Several reports have noted racial differences in the prevalence of p53 genotypes at the codon 72 in patients with endometriosis.To study the association of endometriosis with p53 codon 72 polymorphism in the population of Isfahan. Materials and Methods: We undertook a case–control study to examine the possible...

We conducted a global-scale study to identify H. pylori antimicrobial-resistant genes (ARG), address their global distribution, and understand effect on the antimicrobial resistance (AMR) phenotypes of clinical isolates. identified ARG using several well-known tools against extensive bacterial databases, then analyzed correlation with antibiogram data from dozens patients across countries. This...

introduction: iron overload has been implicated as an important factor for nephropathy by hydroxyl radicals production. on the other hand nitric oxide (no) asa reactive free radical, has numerous effects on kidney. however at high concentration it has been suggested to have toxic effects. in this study the interaction between iron overload and no system on renal function were evaluated in rats....

Background:Many case-control investigations have showed the correlation of TP53 gene polymorphisms with the risk of breast cancer. However, the findings are not consistent. It has been suggested that the investigation of P53 genotype combinations and haplotypes may be more helpful than the detection of single polymorphisms. In the present study, we investigate...

conclusions the findings of this study reveal that both arg-1 and gpc-3 are helpful ihc markers to separate hcc from cc and ma. furthermore, arg-1 shows 100% sensitivity and 82.6% specificity for the diagnosis of hcc whereas gpc-3 demonstrated 97.7% sensitivity and 91.3% specificity for the diagnosis of this tumor. results arginase-1 and gpc-3 demonstrated diffuse staining, as reactivity in > 9...

Abstract We have studied the antimicrobial and hemolytic activity of synthetic peptides (SAMPs), i.e., Arg 9 Phe 2 ( P1 -Arg), Lys P2 -Lys), His P3 -His), which a “linear” type amphipathicity contain cationic amino acid residues arginine, lysine, or histidine. In this study, we used various pathogenic microorganism strains gram-negative bacteria Pseudomonas aeruginosa , Escherichia coli, Salmon...
