In scheduling, it is important to maintain the terminal inventory levels above threshold values to prevent stockout. However, simply enforcing the terminal inventory level above a lead-time-based threshold for each product, as it is common practice, does not exploit the relationships of inventory levels among products. To overcome this drawback, we propose a new type of terminal constraints for...
Background: The etiology of End Stage Renal Disease (ESRD) in every community differ according to genetic, nutrition, and public health status. ESRD,the terminal stage of chronic renal failure,needs replacement therapy otherwise could lead to death. The aim of the study is to determine the relative frequency of ESRD etiology in hemodialysis patients of Gilan province. Methods:This descriptive s...
Background: The smiley face rod method is an effective treatment for symptomatic terminal-stage spondylolysis. However, the risk factors failure are unknown. We investigated association of pars defect type with outcomes this method.
FtsZ and ZipA are essential components of the septal ring apparatus, which mediates cell division in Escherichia coli. FtsZ is a cytoplasmic tubulin-like GTPase that forms protofilament-like homopolymers in vitro. In the cell, the protein assembles into a ring structure at the prospective division site early in the division cycle, and this marks the first recognized event in the assembly of the...
آنزیم آلفا آمیلاز از سویه باکتریایی bacillus sp.kr8104 از 422 اسید آمینه تشکیل شده و 48 کیلو دالتون جرم دارد. این آنزیم یک آنزیم ترشحی میباشد که توسط این سویه به فضای خارج سلولی ترشح میشود. این آنزیم دارای دو فرم بالغ و نابالغ می باشد. آیا آنزیم آمیلاز به صورت نابالغ توسط باکتری ترشح میشود و سپس در محیط خارج سلولی بالغ میشود یا به صورت بالغ به خارج از سلول ترشح میشود؟ سوالی است که در مورد این آ...
Differentiation of erythroblasts to mature red blood cells involves dynamic changes of the membrane and cytoskeleton networks that are not fully characterized. Using a mouse fetal liver erythroblast culture system and a targeted shRNA functional screening strategy, we identified a critical role of pleckstrin-2 in actin dynamics and protection of early stage terminal erythroblasts from oxidative...
