[ 2 ] - Synthesis and characterization of physicochemical and immunological properties of recombinant NS3-G2 dendrimer conjugate
Introduction: An effective vaccine against HCV infection is not available. The non-structural protein 3 (NS3) of the virus as an important immunogenic candidate has been utilized in various modules. Nanostructured polymers have been recently used for efficient vaccine and drug delivery. The aim of the current study was the synthesis of rNS3-G2 conjugate and preliminary evaluation of its immunog...
[ 3 ] - اثر اسانس سیر بر رشد باکتری اشرشیاکلی H7:O157 و تولید شیگاتوکسین
زمینه مطالعه: با ارتقای سطح دانش وآگاهی نسبت به مضرات نگهدارنده‌های شیمیایی، تمایل به استفاده از نگهدارنده‌های طبیعی به خصوص اسانس‌ها در مواد غذایی افزایش یافته است. گیاه سیر (.Allium Sativum L) از گیاهان دارویی در طب سنتی ایران بوده و بررسی اثرات ضد میکروبی آن بر روی باکتری‌های بیماریزای مواد غذایی مانند اشرشیاکلی H7:O157 ضروری به نظر می‌رسد. دوز عفونت‌زایی اشرشیاکلی H7:O157 درانسان بسیار کم ...
[ 4 ] - عملکرد و کاربردهای پزشکی وزیکول های خارج سلولی باکتری ها
وزیکول های خارج سلولی، ذراتی در اندازه نانومتری هستند که در حدود پنجاه سال پیش مورد شناسایی قرار گرفتند. از زمانی شناسایی این نانوساختارها مشخص گردید که تقریبا همه باکتری های گرم منفی در طی رشد طبیعی خود وزیکول های خارج سلولی را ترشح میکنند. امروزه تولید وزیکول های غشایی توسط باکتری های گرم مثبت، انگل ها، قارچ ها و مایکوباکتری ها گزارش گردیده است. از آنجایی که این ذرات نانومتری بسیاری ا...
[ 5 ] - ژن‌های سرطان/بیضه، معرفی ژن TSGA10: مقاله مروری
Cancer/Testis antigens (CTAs) as a group of tumor antigens are the novel subjects for developing cancer vaccine and immunotherapy approaches. They aberrantly express in tumors with highest normal expression in testis, and limited or no expression in normal tissues. There are important similarities between the processes of germ-cell and cancer cell development Spermatogenesis begins at puberty w...
[ 6 ] - بررسی بیان ژن Tsga10 در فرایند تمایز سلول‌های بنیادی جنینی موشی به سلول‌های ژرمینال در محیط آزمایشگاهی
Background: About 15% of couples have fertility problems and male factor in fertility accounts for half of the cases. In vitro generation of germ cells introduces a novel approach to male infertility and provides an effective system in gene tracking studies, however many aspects of this process have remained unclear. We aimed to promote mouse embryonic stem cells (mESCs) differentiation into ge...
[ 7 ] - جابه‌جایی دو طرفه متعادل کروموزوم‌های 5 و 18: گزارش موردی
Background: A balanced reciprocal translocation is a structural abnormality, which at least consist of breakage of two non-homologous chromosomes along with pieces exchange and form quadrivalant structure that can produce unbalanced chromosomes during meiosis I and result in a fetus abortion. The aim of the present study is to offer using preimplantation genetic diagnosis (PGD) 24sure array, wh...
[ 8 ] - بررسی بیان miR-520d در سرطان پستان
Background: Breast cancer is the most common cancer in women. Non-coding RNAs especially miRNAs have important regulatory roles in cancer. MiRNAs are 21-24 nucleotides which have different levels of expression between tumors and normal tissues. In this study, we have analyzed expression level of miR-520d in three different groups of breast cancer.Methods: Fifty nine samples were divided into di...
[ 9 ] - Evaluation of the Effect of Zinc Oxide Nanoparticles on the Inhibition of Biofilm formation of standard Pathogenic Bacteria and Comparison with Drug Resistant Isolates
Introduction: Traditional medicines cannot adequately reach the target tissues, due to their large size; therefore, the attention of researchers has been drawn to the use of nanomedicines. In fact, the use of biological active compounds loaded on the surface of nanoparticles can be effective the in the promotion of their antimicrobial activity. In the earlier studies, it was demonstrated that b...
[ 10 ] - The Impact of Long-term Exposure to Low Levels of Inorganic Arsenic on the Hypomethylation of SEPT9 Promoter in Epithelial-Mesenchymal Transformed Colorectal Cancer Cell Lines
Inorganic arsenicals are worldwide environmental contaminants that affect molecular characteristics in biological systems and lead to genomic and epigenomic instability as well as epithelial mesenchymal transition (EMT). In this study, we aimed to investigate whether low levels of sodium arsenite (iAsIII) can influence EMT and genomic instability through microsatellite analysis. We have also de...
[ 11 ] - Heat shock factor 5 is essential for spermatogenesis in mice: Detected by a new monoclonal antibody
Objective(s): Here, we examined the function of our produced monoclonal antibody (mAb10C3) to recognize one of the most important members of the HEAT shock factor family, Hsf5, in embryonic development and in spermatogenic cells of adult mouse testis.Materials and Methods: The targeting effects of mAb10C3 were investigated by immunohisto...
[ 12 ] - Evaluation of lactic acid bacteria isolated from poultry feces as potential probiotic and its in vitro competitive activity against Salmonella typhimurium
The efficacy of probiotics as alternatives to antibiotics has been defined as one of the potential strategies to prevent Salmonella spp. infection in poultry. The purpose of this study was to isolate probiotic native Lactic acid bacteria (LAB) with high compatibility to intestinal tract and prevention of Salmonella typhimuriumfrom broiler chicken feces. Thirty-seven samples of...
[ 13 ] - Generation of global Spata19 knockout mouse using CRISPR/Cas9 nickase technology
Introduction: SPATA19 gene is expressed in developmental stages of testis and some organs, but so far its function has only been examined in the testis. In this study, we provided an effective pathway for the generation of these mice using new CRISPR / Cas9 nickase method while generating Spata19 knockout mice for future studies in other organs. Materials and Methods: CRISPR / Cas9 nickase plas...
[ 14 ] - Human Reoviruses Serotype 3 Effectively Target Huh-7 Cells
Abstract: Background and Aims: Huh-7 is a cell line that was derived from a liver tumor of a Japanese man. Hepatocellular carcinoma (HCC) is considered as a primary liver cancer. Highly resistant tumor to treatment which causes the death of many patients annually. Thus, targeting the cancer cells by using a new method could be effective in...
[ 15 ] - Review on the role of host genetic factors in the susceptibility to SARS-CoV-2
Background: Severe acute respiratory system Cov-2 pandemic has affected the world populations for more than one year. Different incidence and severity of this viral disease among various age range and individuals with different background disease may indicate the pivotal role of host genetic factors in their prevalence and mortality rate. In this regards, present study was performed to review t...
