Studies in vitro on the uptake and degradation of sodium hyaluronate in rat liver endothelial cells.
Rat liver endothelial cells in primary cultures at 7 degrees C bind radioactively labelled sodium hyaluronate (HA; Mr 400 000) specifically and with high affinity (Kd = 6 X 10(-11) M). Maximal binding capacity is approx. 10(4) molecules per cell. Inhibition experiments with unlabelled HA and oligosaccharides from HA indicate that each molecule is bound by several receptors acting co-operatively...
OBJECTIVE Hyaluronan (HA) plays a role in keratinocyte proliferation and differentiation. In addition, HA has been shown to have different biological activities depending on its molecular weight. It has been reported that HA-mediated CD44 activation regulates keratinocyte differentiation. Therefore, the aim of this study was to investigate the influence of HA tetrasaccharides (HA4) on the regul...
BACKGROUND Influenza-virus hemagglutinin (HA) protein expressed in insect cells by recombinant baculovirus is a candidate influenza vaccine. METHODS In a randomized, double-blind trial conducted in 399 adults > or = 65 years of age, the efficacy of trivalent inactivated influenza vaccine (TIV) licensed for intramuscular injection was compared with that of trivalent baculovirus-expressed HA va...
این آزمایش جهت بررسی اثرات کودهای تلفیقی (کود گاوی و کود نیتروژنه) و کود آهن بر روی عملکرد کمی و کیفی آفتابگردان آذرگل در مزرعه تحقیقاتی دانشگاه شهید باهنر کرمان در یک خاک آهکی به اجرا در آمد. این بررسی بصورت اسپلیت پلات در قالب طرح بلوک های کامل تصادفی و در 3 تکرار پیاده گردید. تیمارهای آزمایشی شامل کرت اصلی ( t/ha 14 کود گاوی + kg/ha 217 کود اوره) = t1 ، ( t/ha 12 کود گاوی + kg/ha 261 کود اور...
