the aim of the present study was to assess whether near infrared reflectance spectroscopy (nirs) and regression equations are the practical and accurate approach of nutritional assessment of common feedstuffs. therefore two experiments were conducted to study the effect of amino acid determination methods on broiler performance. in experiment i, two hundred thirty four male ross broiler chicks ...

staphylococcus aureus is an opportunistic pathogen and remains a common cause of burn wound infections. different studies have shown that entrapment of plant-derived compounds into liposomes could increase their anti-staphylococcus aureus activity. silymarin is the bioactive extract from the known plant silybum marianum l. the objective of this study was to evaluate efficacy of silymarin in fre...

background: based on literature, in vitro cholesterol removal of lactic acid bacteria has been accounted for their in vivo cholesterol reduction. but recently, it has been proposed that such in vitro characteristic may not be directly relevant to their in vivo activity. the objective of this study was to find how much in vitro cholesterol reducing potential of lactobacillus plantarum a7 (la7), ...

objective(s): ex vivo expansion of hematopoitic stem cells is an alternative way to increase umbilical cord blood (ucb)-cd34+ cells for bone marrow transplantation. for this purpose demineralized bone matrix (dbm) and mineralized bone allograft (mba) as two scaffolds based on bone matrix and stem cell niche, were simultaneously used to enhance the effect of human mesenchymal progenitor cells (m...

objective(s): investigation of acute effect on cellular bioenergetics provides the opportunity to characterize the possible adverse effects of drugs more comprehensively. this study aimed to investigate the changes in biochemical and biophysical properties of heart mitochondria induced by captopril and nifedipine antihypertensive treatment. materials and methods: male, 12-week-old wistar rats i...

background : immunogenicity of streptokinase (stk), as a thrombolytic drug, have limited its clinical use. elimination of the amino acid residues that are responsible for immunogenicity while don’t affect the bioactivity of stk is worthy. recently, we modified the stk through elimination of 42 amino acids from its’ c-terminal and assessed its bioactivity in vitro . objective : in this study, bi...
