[ 1 ] - اثرات سیتوتوکسیک ترکیب لانوسترول استخراج شده از خیار دریایی گونه Holothuria leucospilota از جزیره هنگام، خلیج فارس
با توجه به فراوانی گونه Holothuria leucospilotaدر خلیج فارس و تولید ترکیبات ترپنوئیدی با خواص سیتوتوکسیک توسط آن‌ها، در این پژوهش به بررسی خواص سیتوتوکسیک ترکیب لانوسترول، نوعی تری‌ترپنوئید، پرداخته شده است. به این ترتیب که نمونه‌های پودر خشک خیار دریایی با استفاه از استون عصاره‌گیری شدند. سپس به منظور جداسازی ترکیب لانوسترول عصاره توسط ستون کروماتوگرافی سیلیکاژل با حلال‌های ان‌هگزان و اتیل است...
[ 2 ] - اثر ترکیبات جدید 8- فنیل - 4- کینولون با استخلاف‌های مختلف در موقعیت 3 بازدارنده آنزیم اینتگراز علیه ویروس HIV
زمینه و هدف : تهدید HIV علیه نظام سلامت جهانی، سبب مطالعاتی برای یافتن ترکیبات جدید ضدویروس HIV شده است. این مطالعه به منظور تعیین اثر ترکیبات جدید 8- فنیل - 4- کینولون با استخلاف‌های مختلف در موقعیت 3 بازدارنده آنزیم اینتگراز علیه ویروس HIV انجام شد. روش بررسی : در این مطالعه توصیفی ویریون (single cycle replicable) HIV SCR به وسیله ترانسفکت کردن سلول‌های HEK293T با سه پلاسمید pmzNL4-3 ، pSPAX....
[ 3 ] - In vitro Assessment of Antiviral Activity of Cold Atmospheric Pressure Plasma Jet against the Human Immunodeficiency Virus (HIV)
Introduction: The human immunodeficiency virus (HIV) is a threat to global health and the need for finding new methods of antivirus research, in particular against HIV has increased in recent years. In this study, we investigated the ability of the cold atmospheric pressure plasma jet (CAPPJ) using helium to inhibit the replication of HIV virions. Methods: Single cycle replicable HIV (SCR-HIV) ...
[ 4 ] - Cloning and expression of hepatitis E virus ORF2 as a vaccine candidate
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...
[ 5 ] - 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...
[ 6 ] - Establishment of NS3 tumor cell line expressing Hepatitis C virus Non-structural Protein 3 as valuable tool for HCV challenging in mice
Introduction: Hepatitis C virus (HCV) is one of the major medical problems. Human and chimpanzees are the only specific hosts which are naturally susceptible to HCV infection. Mice and other common laboratory animals are resistant to the virus, hence HCV prophylactic and therapeutic researches are very difficult and challenging. HCV non-structural protein 3 (NS3) is one of the most attractive t...

[ 8 ] - Assessment of humoral immune response of a Cytomegalovirus DNA-vaccine candidate in BALB/c mice
Introduction: Glycoprotein B (gB) is the major antigen for induction of humoral responses against human cytomegalovirus (HCMV) making it an attractive candidate for immune prophylaxis. In the present study, the humoral immune response of BALB/c mice to a truncated HCMV gB protein fused with GFP was evaluated. Methods: The truncated gB coding sequence was synthesized and cloned in pEGFPN1 eukary...
[ 9 ] - Design, cloning, expression and evaluation of cysteine-substitutes of intact and truncated molecules of streptokinase
Introduction: Thrombosis and the blockage of blood vessels with clots, can lead to acute myocardial infarction and some times even death. Aside from surgical interventions to remove the blockage, the only available treatment is the administration of thrombolytic agents to dissolve the blood clot. Streptokinase (SK) is the most commonly used fibrinolytic drug for this purpose. However, SK...
[ 10 ] - Gut Microbiota and Chronic Hepatitis B and C Viruses-Induced Cirrhosis
Hepatitis B and C viruses are major public health problems. These viruses can chronically lead to liver disease such as fibrosis, cirrhosis, and hepatocellular carcinoma, which often increase mortality in these patients. According to previous studies, the liver is highly affected by changes in the microbiota of gastrointestinal tract and immune system damage caused by inflammation due to viral ...
