Objective(s):Multi-epitopic protein vaccines and direction of vaccine delivery to dendritic cells (DCs) are promising approaches for enhancing immune responses against mutable pathogens. Escherichia coli is current host for expression of recombinant proteins, and it is important to optimize expression condition. The aim of this study was the optimization of multi-epitopic HIV-1 tat/pol/gag/env ...
Background: Vaccines have played a special role in controlling and reducing mortality from infectious diseases. In this regard, DNA vaccines were developed to ease the production and reduce the risks of traditional vaccines. Human papillomavirus (HPV) has been introduced as the causing agent of cervical cancer. The capsid protein (L1) of HPV has been used to produce subunit and DNA vaccines. Th...
A new method of optimization on linear parabolic solar collectors using exergy analysis is presented. A comprehensive mathematical modeling of thermal and optical performance is simulated and geometrical and thermodynamic parameters were assumed as optimization variables. By applying a derived expression for exergy efficiency, exergy losses were generated and the optimum design and operating co...
Background: Improving the performance of HIV diagnosis assays is one of the most important ways to reduce HIV transmission. Because of the high mutation rate of HIV, it is critical to use the conserved proteins to develop diagnostic immunoassay methods. Because integrase is one of the most conserved proteins of HIV, it may be a good target for this purpose. In this paper cloning, purification a...
Abstract Background: This study was performed on the base of importance of phenylalanine dehydrogenase (PheDH) in the outbreak of phenylketonuria (PKU). In order for PKU screening one of the medical applications of enzyme is, identifying and quantifying the exact amount of L-phe in blood serum. The research question was whether the level of protein expression changes after optimization of codon...
conclusions the obtained results indicate that rsm is an effective method for the optimization of culture conditions for hes gene expression in e. coli. results a maximum rhes mrna level of 376.16% was obtained under the following conditions: 0.6 mm iptg, 7 hours post-induction time, and 0.9 cell density before induction. the level of rhes mrna was significantly correlated with post-induction t...
Background: Human papilloma virus is a DNA virus from the papillomavirus family that is most prevalent in human cervical cancers and many studies showed the E6 and E7 proteins are present in the majority of cervical cancer cases. Development of universal HPV peptide-based vaccine with more serotypes coverage has considerable value. The aim of the study was to design a multi-epitope universal va...
Background and Objective: In recent years, the biological methods have been considered as a most promising candidate for the cancer treatment. One of the most applicable methods is recombinant proteins. ONTAK immunotoxin is a special drug for cancer therapy of leukemia, lymphoma and melanoma. With respect to the dramatic growth of cancer in today's society, production of recombinant prot...
in order to study the periplasmic expression of human growth hormone (hgh) in escherichia coli, the related cdna was inserted in two expression plasmids carrying pelb signal peptide, one with lac bacterial promoter and the other with a bacteriophage t7-based promoter. the recombinant plasmids were moved to tg1 and bl21 strains of e. coli, respectively. to induce the expression systems, iptg and...
در این مطالعه اثر داروهای آدرنرژیک بر بروز (expression) و گسترش (development) تولرانس به اثرات بی دردی مرفین در فرمالین تست بررسی شده است. در نهایت چنین نتیجه گیری می شود که مکانیسمهای شa2 آدرنوسپتور ممکن است در بی دردی و تولرانس ناشی از مرفین دخیل باشند.
