A numberof antimicrobial agents possess the structural unit which is a derivative of 7, 8, 9, 10-tetrahydrotetracene quinone (5, 12) present in glycosidic union with oneor more sugar units. The term anthracyclines was proposed for this group15. The recognition that one of the members, daunomycin exhibited some antitumor activity focused fresh attention on this group of compounds2). We wish to r...

The main concerns about adverse effects of genetically modified (GM) foods on health are the transfer of antibiotic resistance, toxicity and allergenicity. There are two issues from an allergic standpoint. First, the transfer of a known allergen may occur from a crop into a non-allergenic target crop. The second scenario is the creation of a neo-allergen where de novo sensitisation occurs in th...

Recent studies in normal men have demonstrated that soy products have a pronounced inhibitory effect on the absorption of nonheme dietary iron. The purpose of the present investigation was to explore approaches to overcoming this inhibition. A modest but significant increase in iron absorption was observed when test meals containing either isolated soy protein or whole soybeans were baked at 20...

due to the importance of adult artemia in aquaculture, information regarding the digestive enzyme activities variation with inexpensive diets has great importance in artemia at different life stages. in this study, the effect of different inexpensive diets on digestive enzyme activities, including trypsin, amylse and lipase of artemia urmiana was investigated in different life stages. the exper...

I t has been generally assumed that the nutritive value of protein feeds for ruminant animals is not influenced by the chemical and physical properties of the proteins. Several recent investigations have shown that proteins with a high solubility are degraded in the rumen to ammonia at a rate too rapid for efficient utilization. The rumen micro-organisms can then utilize only a relatively small...

In this study the effect of different nitrogen source substrates on the amount of chitosan production by Aspergillus niger was investigated. A. niger PTCC 5012 from the Persian Type Culture Collection (PTCC) was grown on soy bean, corn seed and canola residues at 30 °C for specified cultivation days under sterilized conditions. ...

in this research to investigate of the effect of tannin`s type and level on rumenal degradation of soybean meal (sbm) and canola meal (cm), two experiments have be done. at first experiment supplements were treated by semi-pure tannin of pomegranate-pistachio (pp), in different levels (0, 10 and 15 % of dm for sbm and 0, 5 and 10% of dm for cm). in second experiment, these supplements were trea...

BACKGROUND Leucine (Leu) regulates muscle protein synthesis (MPS) producing dose-dependent plasma Leu and MPS responses from free amino acid solutions. This study examined the role of Leu content from dietary proteins in regulation of MPS after complete meals. METHODS Experiment 1 examined 4 protein sources (wheat, soy, egg, and whey) with different Leu concentrations (6.8, 8.0, 8.8, and 10.9...

BACKGROUND To reduce use of main feed ingredient like corn, soy bean meal (SBM) and wheat, alternative ingredients has been studied like copra meal (CM). Production amount of CM which has been high makes CM to be an alternative feed stuff. However, low digestibility on AA and low energy content by high fiber content can be an obstacle for using CM. This experiment was conducted to evaluate the ...
