BACKGROUND The ability to compose biological systems from smaller elements that act independently of the other upon assembly may help make the forward engineering of biological systems practical. Engineering biology in this manner is made difficult by the inherent nonlinear response of organisms to genetic devices. Devices are inevitably coupled to one another in the cell because they share the...

Luxembourg notified to the European Commission its scientific arguments justifying the implementation of a national safeguard measure prohibiting the placing on the market of GM potato EH92527-1 for cultivation purposes in Luxembourg, after which the European Commission asked the European Food Safety Authority (EFSA) to assess the scientific information supporting the prohibition. Having consid...

Sugarcane (Saccharum officinarum L.) is the most important food and energy crop worldwide. In present study, an efficient Agrobacterium mediated transformation regeneration system for sugarcane cultivar SPF-234 was established. tumefaciens strains EHA101and LBA4404 using vector pIG121 Hm, having GUS, HPTII NPTII genes were used. Polymerase chain reaction (PCR) histochemical assays confirmed GUS...

زمینه و هدف: کم‌تحرکی در مقابل آن تمرین جزء عوامل مرتبط با شاخص‌های آسیب کبدی به‌شمار می‌روند. وجود این هنوز نقش بسیاری از تمرین‌های ورزشی به‌ویژه تمرینات تناوبی مقاومتی مصرف برخی مکمل‌های غذایی جمله اسپیرولینا بر ایمنی التهابی کاملاٌ شناخته نشده است؛ بنابراین هدف پژوهش تعیین اثر هشت هفته مکمل‌دهی هوازی فعالیت بافت کبد بیان ژن CXCL1 عضلة موش‌های صحرایی نر بود.مواد روش‌ها: نیمه‌تجربی، 60 سر موش ن...

The plausibility that life was imported to Earth from elsewhere can be tested by subjecting life-forms to space travel. Ultraviolet light is the major liability in short-term exposures (Horneck et al., 2001 ), and plant seeds, tardigrades, and lichens-but not microorganisms and their spores-are candidates for long-term survival (Anikeeva et al., 1990 ; Sancho et al., 2007 ; Jönsson et al., 2008...
