The Bacillus megaterium protein production system based on the inducible promoter of the xyl operon (P(xylA)) was systematically optimized. Multiple changes in basic promoter elements, such as the -10 and -35 region and the ribosome-binding site, resulted in an 18-fold increase of protein production compared to the production of the previously established system. The production in shaking-flask...

In rate−distortion optimized video coding, such as H.264, a macroblock uses either Inter or Intra prediction as its compensation method, which exploits temporal or spatial correlation alternatively for compression. In this paper, analysis and experimental results show that Inter and Intra prediction can be combined to generate a more accurate prediction especially for high definition video. A w...

traumatic brain injury is a leading cause of disability and death from injury in the world. the interleukin-1 (il-1) is a family of cytokines that act as key mediators of the inflammatory response peripherally and centrally. based on many studies, researchers found that the il-1 is the well-known molecule in relation to acute tbi in the models of both focal and diffuse injuries. the il-1 family...

background hepatitis c virus (hcv) is a major cause of chronic liver disease worldwide. the role of intra familial hcv transmission is still controversial. the aim of the present study is to determine intra familial transmission (sexual and non sexual contacts) of hcv in a group of iranian population. patients and methods in this historical cohort study, 270 first degree relatives of hepatitis ...

objective: to determine the preventive effects of local administration of simvastatin for postoperative intra-abdominal adhesion formation in animal model of rat . methods: in this experimental study, 32 wistar albino rats as the animal model of intra-abdominal adhesion formation were included. adhesions were induced in all the animals via abrasion of the peritoneal and intestinal surface durin...

intra-industry trade (iit) comprises of instantaneous imports and exports of goods and services which are handled in a same industry. the importance of iit between trading partners refers to those tradable products that provide them with diversity and high technology. to expand its foreign trade relations, iran indeed requires such trade patterns that include diversification of goods and servic...

vernonia galamensis cass is a huge potential industrial crop with very high content of vernolic acid in the seed oil. the experiment was carried out to determine the effect of inter- and intra- row spacing on the yield and yield related traits of vernonia galamensis cas.the experiment was conducted for two years during 2014-2015 on experimental field of wondo genet agricultural research center,...
