[ 1 ] - Intrahippocampal Injection of 3α Diol (a Testosterone Metabolite ) and Indomethacin (3α-HSD Blocker), Impair Acquisition of Spatial Learning and Memory in Adult Male Rats

Hippocampus is essentially involved in learning and memory processes, and is known to be a target for androgen actions. The high density of the androgen receptors in hippocampus shows that there must be some relationship between androgens and memory. Androgen effects on spatial memory are complex and contradictory. Some evidence suggests a positive correlation between androgens and spatial memo...

[ 3 ] - بررسی اثر ماندگاری تزریق بتا آمیلویید در ناحیه CA1 هیپوکامپ موش‌های صحرایی نر بالغ بر یادگیری و حافظه فضایی

سابقه و هدف: آلزایمر یکی از شایع ترین بیماری های تحلیل برنده سیستم عصبی است که منجر به از دست رفتن توان فکری، رفتاری و توانایی یادگیری می گردد. هدف از انجام این مطالعه بررسی ماندگاری اثر تزریق بتا آمیلویید ۴۲-۱ در ناحیه CA1 هیپوکامپ موش های صحرایی نر بالغ بر یادگیری و حافظه فضایی توسط ماز آبی موریس می باشد. مواد و روش ها: در این مطالعه از ۴۲ سر موش صحرایی نر بالغ استفاده شد که به طور تصادفی د...

[ 4 ] - تولید پروتئین نوترکیب Tax ویروس HTLV 1 در سویه باکتریایی Rosetta DE3

زمینه و اهداف:HTLV1 اولین رتروویروس انسانی شناخته شده است که در انسان تولید بیماری میکند. عمده فیزیوپاتولوژی بیماری های مربوط به HTLV1 به خصوصیات پروتین Tax این ویروس مربوط می شود. استفاده از گونه های جهش یافته پروتین Tax در کنار دارو های تنظیم کننده سیستم ایمنی می تواند به عنوان تعدیل کننده پاسخ های ایمنی قوی در طراحی واکسن بکار گرفته شود. این پاسخ های ایمنی مضر،باعث بیماری HAM-TSP میشود و تع...

[ 5 ] - An Enterovirus-Like RNA Construct for Colon Cancer Suicide Gene Therapy

Background: In gene therapy, the use of RNA molecules as therapeutic agents has shown advantages over plasmid DNA, including higher levels of safety. However, transient nature of RNA has been a major obstacle in application of RNA in gene therapy. Methods: Here, we used the internal ribosomal entry site of encephalomyocarditis virus and the 3’ non-translated region of Poliovirus to design an en...

[ 6 ] - An HIV-1 Mini Vaccine Induced Long-lived Cellular and Humoral Immune Responses

Memory formation is the most important aspect of a vaccine which can guarantee long-lasting immunity and protection. The main aim of the present study was to evaluate the memory immune responses after immunization with a mini vaccine. Mice were immunized with human immunodeficiency virus-1 P24-Nef fusion peptide and then cellular and humoral immune responses were evaluated. In order to determin...

[ 7 ] - Protein Kinase Cε in the Platelet and Hippocampal Tissue as a Diagnostic Biological Marker in Alzheimer Disease

Introduction: Alzheimer disease (AD) is a neurodegenerative disorder characterized by the progressive loss of memory and other cognitive functions. Protein kinase Cε (PKCε) is an isoform that most effectively suppresses amyloid beta (Aβ) production and synaptic loss. Methods: In this study, spatial learning and memory for treated rats were evaluated by the Morris water maze test. The activity ...

[ 8 ] - Developing oncolytic Herpes simplex virus type 1 through UL39 knockout by CRISPR-Cas9

Objective(s): Oncolytic Herpes simplex virus type 1 (HSV-1) has emerged as a promising strategy for cancer therapy. However, development of novel oncolytic mutants has remained a major challenge owing to low efficiency of conventional genome editing methods. Recently, CRISPR-Cas9 has revolutionized genome editing.Materials and Methods: I...
