Background and purpose: Probiotics and prebiotics are new concepts which have been demonstrated to positively modulate the intestinal micro flora and could promote host health. The aim of this study was to evaluate the effects of prebiotics on production of antimicrobial properties of Lactobacillus acidophilus ATCC4356 ، Lactobacillus plantarum ATCC 8014 Lactobacillus fermentum ATCC 9338 La...
هدف : بررسی توان باکتری‌های اسید لاکتیک جدا شده از مرغ در مهار رشد باکتری‌های پاتوژن اشریشیاکلی و سالمونلا. روش : در این پژوهش از قسمتهای مختلف دستگاه گوارش مرغهای سالم به وسیله لوب استریل نمونه برداری صورت گرفت و به محیط کشت MRS broth منتقل شد. پس از 24 ساعت گرمخانه گذاری در دمای 37 درجه سانتیگراد بر روی محیط‌های Rogosa agar و MRS کشت خطی انجام شد و به صورت بیهوازی و هوازی به مدت 24 و 48 ساعت...

The human aspartyl (asparaginyl) beta-hydroxylase (HAAH) is a highly conserved enzyme that hydroxylates epidermal growth factor-like domains in transformation-associated proteins. We previously reported overexpression of the HAAH gene in human hepatocellular carcinomas and cholangiocarcinomas (L. Lavaissiere et al., J. Clin. Investig., 98: 1313-1323, 1996). In the present study, we determined w...
