objective(s): hepatitis c is a major cause of liver failure worldwide. current therapies applied for this disease are not fully effective and produce side effects in most cases. non-structural protein 3 helicase (ns3) of hcv is one of the key enzymes in viral replication and infection. therefore, this region is a promising target to design new drugs and therapies against hcv infection. the aim ...

Background: Polycyclic aromatic hydrocarbons (PAHs) such as phenanthrene (Phe) represent one of the most abundant forms of organic pollutants. The aim of this study was to assess changes in plasma levels of aminotransferase enzymes, total protein and liver tissue as biomarkers of yellowfin seabream (Acanthopagrus latus) exposed to Phe for 14 d. Methods: The research was carried out in Januar...

Protein kinase Cs (PKCs) are activated by antigen receptors in lymphocytes, but little is known about proximal targets for PKCs in antigen receptor-mediated responses. In this report, we define a role for diacylglycerol-regulated PKC isoforms in controlling the activity of the serine/threonine kinase protein kinase D (PKD; also known as PKC mu) in T cells, B cells, and mast cells. Antigen recep...

productive and reproductive traits have great importance in international dairy cattle breeding objectives. production, reproduction (days open and calving interval) and pedigree data of iranian holstein dairy cattles were collected between 2002 and 2012 from 47 herds in isfahan province. the data set consisted of 30179 records from 18837 registered iranianholstein dairy cattles. single trait r...

d/l-Hybrid peptides are an attractive class of molecular modality because they able to exhibit high proteolytic stability and unique structural diversity which cannot be accessed by those consisting only proteinogenic l-amino acids. Despite such expectation, it has not been possible devise de novo d/l-hybrid capable disrupting the function a protein target(s) due lack effective method that reli...

This trial tested whether rumen-protected Lys (RPL) supplementation would improve the nutritive value of rumen-undegradable protein (RUP) from corn protein. Thirty-two lactating Holstein cows were blocked by days in milk and parity into 8 squares 4 each replicated × Latin squares. Treatments provided all supplemental crude from: (1) soy (67% expeller soybean meal plus 33% solvent meal); (2) a b...
