جهت بهینه سازی شرایط تولید پروتئین هیدرولیز شده (شامل نسبت آنزیم به سوبسترا، دما و زمان) به منظور دستیابی به بالاترین خواص آنتی اکسیدانی، مینس تهیه شده از ضایعات میگوی ببری سبز (penaeus semisulcatus) پس از تعیین درصد پروتئین آن (13%، بر اساس وزن تر) با استفاده از دو پروتئاز تجاری آلکالاز و فلاورزایم بر اساس 18 تیمار تعیین شده با طرح آزمایشات سطح پاسخ برای هر آنزیم، هیدرولیز شده و با خشک کن انجم...
effects of yeast extract (ye) (0, 0.05, 0.1, 0.2, 0.5 and 1%) were investigated on rosmarinic acid (ra) accumulation and tyrosine aminotransferase (tat) gene expression in melissa officinalis seedlings at different time intervals (4 and 17 hours). based on the results, only ye concentrations of 0.05%, 0.1%, and 0.2%, for the 17-hour treatment, significantly stimulated ra biosynthesis pathway. a...
this study evaluated the effect of the intermittent light program on serum and brain melatonin concentrations, antioxidant enzyme activities, and homocysteine concentration in broiler chickens. a total of 60 one-day-old broiler chickens (cobb 500) were distributed in three light-proof controlled rooms (20 chicks per room). all birds were reared in continuous light until 3 days of age. then, chi...
understanding of physiological responses of salt tolerance might be lead to identify main salt tolerance mechanisms and essential approaches for improving grain yield stability, and also to select salt tolerant wheat cultivars. thus, the effects of salinity were investigated on grain yield and some of the characteristics related to salt tolerance. six wheat cultivars (roshan, kavir, karchia, ga...
Background and Objective: Aminopeptidases remove the amino acids from the N-terminal of proteins and peptides. Aminopeptidase N (CD13) and leucine aminopeptidase are involved in processing and presentation of pathogens to immune cells. Also, enzyme activity in some viral infection and tumors are high. In this study, the activity of CD13 in serum with high level of brucella antibody wa...
the objective of this study was to produce fish protein hydrolysate (fph) with the most antioxidant activity, by enzymatic hydrolysis from (carassius carassius). the protein of crucian carp a low value fish was hydrolyzed by alcalase 2.4l and the optimal hydrolysis parameters of strongest antioxidant capacity of peptides were obtained using response surface methodology (rsm) by the central rota...
Background: Thymus species have significant amounts of phenolic and flavonoid compounds and demonstrate strong antioxidant activities. Paraoxonase1 act as antioxidant enzyme and protect the low-density lipoprotein against oxidation. In our study we aimed to evaluate the antioxidant capacity of Thymus Kotschyanus Hydroalcoholic extract and its effect on serum paraoxonase 1 activity in healthy an...
Background and Objectives: The results of observations and studies over the years have shown that health and nutrition are highly related with each other. Bioactive peptides are defined as hydrolyzed proteins, which have the ability to stimulate the desired activities. In this study, the effect of adding pepsin enzyme on orange seed protein was investigated to obtain the hydrolyzed protein, and...
The number of patients with end-stage renal disease is growing rapidly in Asia. Patients with end stage renal disease failure (ESRD) undergoing long term hemodialysis (HD) are at risk for high oxidative stress. There is paucity of information with regard to oxidative stress during HD. Therefore, the aim of the present study was to evaluate catalase enzyme activity in erythrocytes and the total ...
abstract crop residues are well known for their chemical (allelopathic) effects on crops. the allelopathic potential of the aqueous extracts and chopped residual of sorghum (sorghum bicolor l.) on germination, seedling growth, relative water content, seedling dry weight, seedling length and antioxidant enzyme activity namely catalase (cat), peroxidase (pod) and superoxide dismutase (sod) of...
