Introduction: Human growth hormone (HGH) is very important pharmaceutical substance which is used as an absolute cure for different diseases that is why the production of HGH recombinant is taken into consideration not only nationally but also internationally. Many different methods and host systems have been used as growth hormone factories. Finding new and efficient hosts for recombinant mole...
introduction: cryptorchidism has been proved to cause apoptosis in germ cells in respond to changes in the stimulation levels of specific physiological events. the purpose of this study was to determine whether treatment of bilateral cryptorchidism was associated with alterations in testicular gene expression. methods: to induce bilateral cryptorchid model, immature mice were anesthetized and a...
Drought stress adversely affects a plant’s growth and productivity. Wide ranges of molecular disorders could be caused by the production of reactive oxygen radicals. Plant cells have developed potential systems to prevent such damage by scavenging and reducing the reactive oxygen species (ROS). In this study, both the genotypes of oilseed rape-tolerant and sensitive to drought-were exposed to p...
Introduction: Hepatitis E virus (HEV) is a fecal-oral transmitting virus which causes a chronic liver disease. ORF2 is an immunogen capsid protein of HEV that has been proposed to be used for Hepatitis E vaccine design. It is a 660-amino acid protein which includes an immunogenic region (residues 112-607). This protein has been expressed in complete and truncated forms, using different expressi...
in recent years, recombinant monoclonal antibodies and their derivatives have emerged as important targeted therapy agents. monoclonal antibodies are ex-tremely difficult to produce. so, the cost of production is very high and many people cannot afford these drugs. in this regard, choosing inexpensive and easy ways to manipulate production systems such as bacterial hosts to reduce the cost of m...
different researchers in different parts of the world have investigated the strategies used to translate written works ranging from novels to classroom assignments. however, by the significant increase in the number of postgraduate students in iran in the last few years, a very common kind of translation in iran includes translating abstracts of master’s theses. in this work, the researcher hav...
Telomerase and systems controlling their activity have been of great attention. There are controversies regarding the role of the alternative splicing forms of the human telomerase reverse transcriptase (hTERT), the catalytic subunit of telomerase. Therefore, the correlation between telomerase enzyme activity, the abundance of alternatively spliced variants of hTERT and doubling time of a seri...

The purpose of this study was to determine whether treatment of bilateral cryptorchidism was associated with alterations in testicular gene expression.

Background and Objective: Cholestasis is bile duct obstruction with accumulation of toxic bile acids in liver and circulatory systems and increased toxicity in hepatocytes. Some studies have shown that cholestasis induces spatial memory deficit. Hippocampus plays an important role in this process. In this research, the effect of cholestasis on expression of BCL-XL (B-cell lymphoma-extra large&n...
