Bovine in vitro embryo production (IVP) has been around for about three decades. Over the years, it has gained a reputation as one of the most applicable of the high-tech bovine assisted reproduction techniques. It is well known that its ups and downs are basically driven by economic imperatives depending on the agricultural system in which it is used. In parallel, there has always been a stron...
Fibroblasts are predominant components of mammary stromal cells and play crucial roles in the development and involution of bovine mammary gland; however, whether these cells contribute to mastitis has not been demonstrated. Thus, we have undertaken biological and molecular characterization of inflammation-associated fibroblasts (INFs) extracted from bovine mammary glands with clinical mastitis...
پنل های خورشییدی دارای مشیه ه جریان -ولتاژ غیر خطی بوده و تنها در یک نقطه کار خاص، حداکثر توان را تولید می کنند. این نقطه بهینه توان با تغییر دما و شیدت نور تغییر می کند. روش های مهتلفی برای ردیابی نقطه حداکثر توان به صورت free model و based model معرفی شده است. این تحقیق روش جدیدی جهت بهبود عملکرد ردیابی نقطه حداکثر توان پنل های خورشیدی جدا از شبکه ارائه می دهد و الگوریتم روش پیشینهادی از دو...
to investigate uterine and serum copper (cu) and zinc (zn) concentrations variation duringthe bovine estrus cycle , 232 blood and genital tract samples were collected from the abattoir inurmia. the phase of the estrous cycle was determined by the examination of the ovaries and theuterine tonicity. of the 46 samples selected for use in the study, 13 were pro-estrus, 10 estrus, 8metestrus, and 15...
objectives: in present research we evaluate the expression of this critical enzyme in a eukaryotic system for future use in cheese industry. materials and methods: we have cloned bovine prochymosin gene in methylotrophic yeast, p. pastoris, using ppic9k as an expression vector. the recombinant plasmid was transformed into the host by electroporation, and it was expressed in optimum conditions...
