The use of animals in research is controversial and often takes place under a veil of secrecy. Lab animal technicians responsible for the care of animals at research institutions are sometimes described as performing 'dirty work' (i.e. professions that are viewed as morally tainted), and may be stigmatized by negative perceptions of their job. This study assessed if transparency affects public ...
Lactic acid bacteria (LAB) are frequently encountered inhabitants of the human intestinal tract. A protective layer of mucus covers the epithelial cells of the intestine, offering an attachment site for these bacteria. In this study bioinformatics tools were used to identify and characterize proteins containing one type of mucus-binding domain, called MUB, that is postulated to play an importan...
This study was investigated the above-ground vegetation and soil seed bank flora in three site of Albizia julibrissin Durazz. In Hyrcanian Lowland Forests (including Haloomsar, Anjilisra forests and Sisangan Box tree (Buxus hyrcanus Pojark) reserve). Aboveground vegetation was sampled by 68 plots of 400 m2 during late June and seed bank flora was studied by seedling emergence method. The resu...
مطالعات انجام شده در مورد زنبورهای خانواده‌ی Sphecidae توسط محققان ایرانی محدود است، اما محققان خارجی مطالعات نسبتاً زیادی در مورد زنبورهای این خانواده در ایران انجام داده‌اند. در این مقاله‌ی کوتاه ضمن بررسی اجمالی مطالب منتشر شده در مورد فون این خانواده در ایران، شش گونه برای اولین بار از کشور گزارش می‌شود.
The frequency of lactic acid bacteria (LAB) involved in sauerkraut fermentation with (MDC+) or without (MDC–) the ability to decarboxylate malic acid was determined. The MDC+ phenotype was found in > 99% of homofermentative LAB isolated from commercial fermentations. In contrast, heterofermentative LAB isolates from 0.25, 3, 7, and 10 d had only 53%, 54%, 15%, and 11% MDC+ phenotype, respective...
Lactic acid bacteria (LAB) are essential for the manufacture of fermented dairy products. Studies on the physiology, biochemistry and genetics of these microorganisms over the last century have contributed considerably to the improvement of fermentation processes and have resulted in better and safer products. Nevertheless, the potential of LAB is far from being maximized. The sophistication of...
Members of the Enterovirus genus of the Picornaviridae family are abundant, with common human pathogens that belong to the rhinovirus (HRV) and enterovirus (EV) species, including diverse echo-, coxsackie- and polioviruses. They cause a wide spectrum of clinical manifestations ranging from asymptomatic to severe diseases with neurological and/or cardiac manifestations. Pandemic outbreaks of EVs...
