This study was carried out to investigate the effects of dietary putrescine (PUT) on broiler’s response fed low crude protein (CP) diets. A total of 192 male day old chicks were fed with four dietary treatments including two levels of PUT (0 and 0.03%) and two levels of CP (normal and low) with factorial combinations. Weekly growth performance, nutrient digestibility and intestinal morphology (...

Once upon a time it was possible for every new programmer to quickly learn how to write readable programs to Create, Read, Update and Delete business information. These so-called CRUD applications, along with reporting, were pervasive throughout business and essentially defined IT or MIS as it was called in those days. These IT design patterns are so pervasive that they were incorporated into n...

background cucumber mosaic virus (cmv) has isometric particles with a diameter of about 28–29 nm. a useful method to recognize regions from mutagenesis in the coat protein (cp) gene are important for particle assembly and the expression of viral in cp expression systems like bacteria such as e.coli or yeast as well as their assembly into virus-like particles (vlp). objectives in this paper, we ...

Four treatments were assigned to determine the effects of dietary potential digestible fiber (pdF) and crude protein (CP) levels in mid lactating Holstein cows on milk production and nitrogen efficiency. Sixteen primiparous (n=8) and multiparous (n=8) Holstein cows (body weight (BW)=546±72 kg; days in milk (DIM)=118±50 day) were allocated to one of four diets in balanced randomized complete des...

background: the advent of recombinant dna technology has facilitated heterologous expression of proteins from various sources in different host systems including escherichia coli. if a plant virus coat protein is expressed in the bacterium it can be used as the antigen for antibody preparation. such a recombinant antigen preparation can be particularly useful where equipment such as ultracentri...

Background and Amis: Serological assay is considered as one of the best choices for conducting large number of infection tests. Recombinant DNA technology has been used for expression of virus coat protein (CP) gene in prokaryotic bacterial cells such as Escherichia coli and the recombinant CP (rCP) is used as immunogen in antibody production. Heterologous CP protein expression and purification...

conclusions this is the first report of expression of cmv cp gene in iran, which is important for the preparation of anti-cmv antibody and paving the way for the use of the virus coat protein as a nanomaterial. results the identity of the expressed protein was confirmed by immunoassays such as western blot, dot-immunobinding assay (diba) and enzyme-linked immunosorbent assay (elisa) by the use ...

objective(s):cyclophosphamide (cp) toxicity on testis was hampered by squid ink polysaccharide (sip) via restoration of antioxidant ability in our previous investigations. this study investigated roles of nrf2/are signal pathway in testis of treated mice. materials and methods: male kunming mice were employed to undergo treatment with sip and/or cp. protein levels of nrf2, keap-1, histone deace...
