This study was designed to evaluate the effect of cyclooxygenase-1 (COX-1) inhibitor, SC-560, combined with cisplatin or taxol, on angiogenesis in human ovarian cancer xenografts. Mice were treated with intraperitoneal (i.p.) injections of SC-560 6 mg/kg/day, i.p. injections of cisplatin 3 mg/kg every other day and i.p. injections of taxol 20 mg/kg once a week for 21 days. Vascular endothelial ...

The objective of this work was to obtain prevalence estimates of cloudy vaginal mucus in artificially inseminated Holstein cows raised under intense heat, in order to assess the effect of meteorological conditions on its occurrence during estrus and to determine its effect on conception rate. In a first study, an association was established between the occurrence of cloudy vaginal mucus during ...
Genetic increases in twinning of cattle could result in increased frequency of triplet or higher-order births. There are no estimates of the incidence of triplets in populations with genetic levels of twinning over 40% because these populations either have not existed or have not been documented. A model of the distribution of litter size in cattle is proposed. Empirical estimates of ovulation ...
کنترل ربات به دلیل غیرخطی و وابسته بودن معادلات دینامیکی سیستم به یکدیگر و عدم شناخت دقیق پارامترهای سیستم، مسأله ای نسبتا پیچیده است. روش های کلاسیک کنترل موقعیت بازوی ربات، عمدتا بر شناسایی مدل دقیق ربات استوار می باشد که در عمل به دلیل وجود پارامترهای ناشناخته موثر در دینامیک ربات از قبیل لقی چرخ دنده ها، اصطکاک بین مفاصل بازوها و غیره، پیدا کردن مدل دقیق دینامیک یک ربات کار بسیار مشکلی می ب...
