background: blindness due to cataract is a major and important problem in pakistan. the problem is expected to increase in future due to increase in tobacco smoking. the aim of study was to look for the mechanism associated with metal deposition and its effect on antioxidant enzymes in lens of smokers in karachi, pakistan. methods: 20 cataract patients were randomly selected from out patient de...
background: besides acute lethal cyanide poisoning, its chronic intoxication may also produce some pathologic effects on different tissues that precedes alterations in biochemical parameters. the present study was aimed to evaluate the effects of sublethal cyanide exposure on some tissue enzyme activities in liver and kidney of rats. methods: twelve male rats were divided into two groups as fol...
objective: the entry of toxoplasma gondii into the bloodstream and other tissues (such as liver, muscle, cardiac muscle, …) of intermediate hosts and its multiplication in nucleated cells may cause changes in plasma levels of various enzymes due to tissue damage. in present study the serum levels of ast, alt, alk/p, cpk, ldh, and acp in rats infected experimentally with toxoplasma gondii have b...
اغلب تکنیک های کاهش فیدبک csi با اجازه دادن به بعضی از کاربران برای فیدبک csi، یا فیدبک اطلاعات نسبی کانال به فرستنده، حجم فیدبک csi را کاهش می دهند. در این پایان نامه، سیستم های network mimo و سیستم های mu-mimo با لینک های فیدبک دارای ظرفیت محدود در نظر گرفته شده است. روش های موثر کاهش فیدبک مبتنی بر استانه های از پیش تعیین شده پیشنهاد خواهد شد که نرخ خالص داده را بیشینه می کند. روش های پیشن...
Bovine heart cytochrome c oxidase is a large multi-component membrane protein containing several phospholipids. X-ray structures of this enzyme at high resolution, determined recently, show a trigonal planar structure of CuB site in the O2 reduction site, which could contribute critically to the four-electron reduction of O2 bound at haem a3, and a hydrogen bond network, through which the proto...
Despite the existence of several three-dimensional structures of cytochrome c oxidases, a detailed understanding of pathways involved in proton movements through the complex remains largely elusive. Next to the two well-established pathways (termed D and K), an additional proton-conducting network ('H-channel') has been proposed for the beef heart enzyme. Yet, our recent mutational studies on c...
Mannose 6-phosphate receptors carry newly synthesized lysosomal hydrolases from the trans-Golgi network to endosomes, then return to the trans-Golgi network for another round of enzyme delivery. Wortmannin, an inhibitor of phosphatidylinositol 3-kinase, interferes with the delivery of newly synthesized lysosomal enzymes to lysosomes. We used two independent assays of mannose 6-phosphate recepto...

Starch, unlike hydrosoluble glycogen particles, aggregates into insoluble, semicrystalline granules. In photosynthetic eukaryotes, the transition to starch accumulation occurred after plastid endosymbiosis from a preexisting cytosolic host glycogen metabolism network. This involved the recruitment of a debranching enzyme of chlamydial pathogen origin. The latter is thought to be responsible for...
