[ 1 ] - ارزیابی اثر ضد باکتریایی عصاره هیدروالکلی خرفه (Portulaca oleracea) بر روی باکتری های پاتوژن انسانی
مقدمه: گیاه خرفه یکی از پر مصرف ترین گیاهان دارویی است. برخی عصاره های گیاهی و ترکیبات شیمیایی آنها دارای اثرات ضد باکتریایی هستند و به عنوان عوامل ضد میکروبی در درمان عفونت ها به کار می روند، شناسایی اثرات ضد باکتریایی این نوع عصاره ها می تواند جایگرین مناسبی برای آنتی بیوتیک باشد. هدف این مطالعه بررسی تأثیر ضد باکتریایی عصاره گیاه خرفه بر روی باکتریهای بیماریزا که مقاومت آنتی بیوتیکی در آن ها...
[ 2 ] - CD4+ T Cells are Exhausted and Show Functional Defects in Chronic Lymphocytic Leukemia
Background: Chronic lymphocytic leukemia (CLL) is the most common adult leukemia in the western world. This health problem is caused due to the accumulation of mature B-lymphocytes in the peripheral blood and bone marrow. In the course of cancer, CD4+ T cells become “exhausted” and characterized with poor effector functions and the expression of multiple inhibitory receptors. Objective: To inve...
[ 3 ] - Blimp-1 Expression as an Exhaustion Transcription Factor in Chronic Lymphocytic Leukemia
Background: PPreviously, it was shown that exhausted CD4+ and CD8+ T cells in chronic lymphocytic leukemia (CLL) co-express the two immune-inhibitory receptors, Tim-3 and PD-1. Present study investigated the expression of Blimp-1, a transcription factor involved in T cell exhaustion, in patients with CLL. Materials and Methods: Peripheral blood mononuclear cells were collected from 25 untreate...
[ 4 ] - Designing an ELISA Method for Measurement of Human IgG and IgM Antibodies against SARS-CoV-2
Background and purpose: Coronavirus disease 2019 (COVID-19) is a respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In this study, an indirect ELISA method was designed to measure the human IgM and IgG antibodies against SARS-CoV-2. Materials and methods: Protein sequence of nucleocapsid antigen from SARS-CoV-2 was expressed in E. coli BL21 and then was...
