chaperones are produced by prokaryotic, yeast and higher eukaryotic cells for various purposes. over-expression of each chaperone or sets of them affect the production level of a recombinant protein in the cell. on the basis of this hypothesis, five different plasmids with 5 different combinations of 6 chaperones molecule, transformed into escherichia coli along with human basic fibroblast grow...

in this paper, we propose a new method for fuzzy numbers. in this method, we assume that ai= (ai1, ai2, ai3, ai4) is to be a fuzzy number. so, the convex combination of ai1 and ai2 and also the convex combination of ai3 and ai4 are obtained separately. then, mic and mis that are to be the convex combinations and the standard deviation respectively we acquire them from these components. finally,...

the holy surah “al- shams” with its effective musical sound is striking in ear and heart and includes various meanings in its few words. shortness of distances and abundance of swears and various contradictions is evident in it which led me to study it in three levels of stylistics: phonetic level, combination level and semantic level.the aim of this study is to explore the beauties of its styl...

glutamate dysregulation may be involved in the neuropathology of schizophrenia. memantine, a drug approved by the fda for the treatment of moderate to severe alzheimer's disease, acts as a partial uncompetitive nmda receptor antagonist. the aim of this study was to examine the efficacy of memantine as an adjunctive treatment to olanzapine in patients with schizophrenia. in this double-blind, pl...

background: trypsin modulating oostatic factor (tmof) terminates trypsin biosynthesis in adult and larval mos­quito gut. it will inhibit the growth and development of mosquito larvae feeding on it resulting in death by starvation. the objective of this study is to determine the effective dose of pichia-tmof and the combination of pichia-tmof with bacillus thuringiensi s ( bt) as larvicide on ae...

the study of the exclosure effects on the vegetation changes undergrazing and non-grazing conditions in the rangeland areas has particularimportance in the rangeland improvement and revivification projects. theresearch was accomplished in semi-steppe khoybilehvar area, from 1999 to2005. vegetation cover was annually measured within fixed plots during transact.the results showed that during nine...

objective: the protective effect of silymarin (smn) on mycophenolate mofetil (mmf)–induced duodenal disorders was investigated. materials and methods: forty-two wistar rats were assigned to seven groups including control and test groups. the control animals received saline and the test animals were treated with mmf (30 mg/kg, orally) and saline, mmf and smn (25, 50, and 100 mg/kg, orally), mmf ...

the error of inertial navigation systems increase versus time, therefore for achieving higher accuracy specially in long time navigations we have to use an aiding system. global positioning system is the best aiding system in this case. in this paper we first simulate a gps and ins; then simulate tightly integration and finally review adaptation method of kalman filtering a fuzzy adaptive kalma...
