three different experiments were conducted to study the effect of dietary astaxanthin on the immune response, resistance to white spot syndrome virus (wssv) and transcription of antioxidant enzyme genes in pacific white shrimp litopenaeus vannamei. each experiment included one triplicate treatment group (fed with 80 mg/kg astaxanthin supplemented diet) and one triplicate control group (fed with...

It is well-known that the typical protein’s three-dimensional structure is relatively unstable in harsh conditions. A practical approach to maintain the folded state and thus improve the stability and activity of proteins in unusual circumstances is to directly apply stabilizing substances such as osmolytes to the protein-containing solutions. Osmolytes as natural occurring organic molecules ty...

Owing to their superior catalytic activity in the extreme conditions, extremozymes have found the potential biotechnological applications for industrial purposes. A robust extracellular protease activity was detected in the culture broth of Salicola marasensis, an extreme halophilic bacterium, after a 48 h-incubation. The effect of different media ingredients in a liquid state fermentation was ...

the present study investigated the effects of e. coli lipopolysaccharide (lps) induced mastitis model in rat on the activity of antioxidant enzyme systems. to achieve this purpose, e. coli lps were infused into the mammary gland of 12 rats 72 hr postpartum and compared with 12 rats in control group infused intramammary placebo sterile pyrogene – free, physiological saline. the antioxidant activ...

Over loading of iron oxide nanoparticles can causes the liver injury through overproduction of free radicals. Zataria multiflora Boiss. (Lamiaceae) has been used for many years in folk medicine due to its antioxidant and antibacterial activities. This study evaluates -for the first time- the effect of Z. multiflora essential oil (EO) against iron oxide nanoparticles hepatotoxicity in rat model....

this study was conducted to determine the effect of dietary turmeric rhizome powder (trp) as a natural antioxidant, and soybean oil, canola oil and tallow on lipid metabolism, blood metabolites, immune system, and antioxidant status of broiler chickens before (bhs, 28 d) and after exposure to heat stress (ahs, 42 d). seven hundred and ninety two d-old male arian broilers were randomly allotted ...

Nitric oxide (NO) is involved in plant responses to many environmental stresses. Transgenic Arabidopsis lines that constitutively express rat neuronal NO synthase (nNOS) were described recently. In this study, it is reported that the nNOS transgenic Arabidopsis plants displayed high levels of osmolytes and increased antioxidant enzyme activities. Transcriptomic analysis identified 601 or 510 ge...
