در این پایان نامه یک الگوریتم متناهی برنامه ریزی دوخطی اولیه- دوگان برای حل دستگاه معادلات قدرمطلق(ax-|x|=b ،(ave که a یک ماتریس n*n است، پیشنهاد می شود. الگوریتم که هیچ فرضی غیر از قابلیت حل روی ave ایجاد نمی کند، شامل یک تعداد متناهی از برنامه ریزی خطی است که منجر به یک جواب ave یا یک نقطه ایستایی از برنامه ریزی دوخطی می شود.
Ribosomal protein S7 from Escherichia coli binds to the lower half of the 3' major domain of 16S rRNA and initiates its folding. It also binds to its own mRNA, the str mRNA, and represses its translation. Using filter binding assays, we show in this study that the same mutations that interfere with S7 binding to 16S rRNA also weaken its affinity for its mRNA. This suggests that the same protein...
Two experiments were conducted to compare performance and metabolic responses of beef females consuming low-quality forages and offered an energy supplement based on fibrous byproducts daily (S7) or 3 times per week (S3) at similar weekly rates. In Exp. 1, BW gain, reproductive performance, mRNA expression of hepatic and skeletal muscle genes associated with nutritional metabolism and growth, a...
BACKGROUND Ribosomal protein S7, a crucial RNA-binding component of the ribosome, is one of two proteins that initiates assembly of the 30S ribosomal subunit. It is required for proper folding of a large 3' domain of 16S ribosomal RNA. S7 regulates its own synthesis by binding to its own mRNA. This ability of S7 to bind both messenger and ribosomal RNAs makes determination of its mode of RNA re...
Cholera-like enterotoxin produced by a non-O1 strain of Vibrio cholerae, S7 (S7 enterotoxin), isolated from human diarrheal stool, was purified, and its physicochemical, biological, and immunological properties were compared with those of cholera enterotoxin from V. cholerae O1 569B (CT) and an enterotoxin produced by another non-O1 V. cholerae (E8498 enterotoxin) reported previously (Yamamoto ...
The stress-responding protein, GADD45α, plays important roles in cell cycle checkpoint, DNA repair and apoptosis. In our recent study, we demonstrate that GADD45α undergoes a dynamic ubiquitination and degradation in vivo, which process can be blocked by the cytotoxic reagent, arsenite, resulting in GADD45α accumulation to activate JNKs cell death pathway, thereby revealing a novel mechanism fo...
