the alginate was extracted with six different methods from iran south seacoast algae, sargassum sp, and the percentage yield of alginate was determined. we divided our methods to two groups including acidic extraction and non-acidic. in acidic methods, hcl and h 2 so 4 were used as a detergent in extraction process and cacl 2 was exerted in non-acidic treatments. all treatments compared with ea...

sulfated polysaccharides have shown promising effects on wound healing processes along with many other biological activities. the sulfated polysaccharides extracted from two algae species habitats in persian gulf were studied in vivo for their effects on collagen formation and epidermal regeneration. the polysaccharides were purified from aqueous extracts of p. tetrastromatica and p. boergeseni...

Background: Fish meat is outlined with high nutritional value having essential amino acids, unsaturated fatty acids, mineral and vitamins. In this short report, we compared the meat quality of rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta fario) farmed in Bulgaria. Methods: Ten fishes from each species were purchased from a fish farm and their morphological parameters were ...

background: brown rice (br) is unpolished rice with various beneficial compounds such as vitamins, magnesium and other minerals, dietary fiber, essential fatty acids, γ‑oryzanol and γ‑aminobutyric acid. in the present study, we compared the effects of white rice (wr) and br on inflammatory marker high‑sensitivity c‑reactive protein (hs‑crp) and cardiovascular risk factors among non‑menopausal o...

caspian brown trout (salmo trutta caspius) is one of the economically valuable species in the caspian sea. artificial propagation and production of larvae are the main problems in the early culture of this species. the purpose of this paper is to study the effect of reproductive performance of female broods on opposition reproduction efficiency in caspian brown trout in the breeding season of 2...
