Objective(s): This study aimed to show the effects of thymoquinone, which is known for its antioxidant, anti-inflammatory, and renal protective effects in contrast-induced nephropathy.Materials and Methods: This is an experimental study in rats. 7 groups were included within the scope of our study: sham-vehicle (n=3), premedication-contr...
Fas Apoptosis Inhibitory Molecule (FAIM) is an evolutionarily highly conserved death receptor antagonist, widely expressed and known to participate in physiological and pathological processes. Two FAIM transcript variants have been characterized to date, namely FAIM short (FAIM-S) and FAIM long (FAIM-L). FAIM-S is ubiquitously expressed and serves as an anti-apoptotic protein in the immune syst...
چکیده micro rna ها rna های کوچک تک رشته ای هستند که بیان ژن هدف را از طریق اتصال به mrna آن و مهار ترجمه ویا تجزیه آن موجب می شوند. mir-9 از روی سه جایگاه کروموزومی شامل (1q22 ) has-mir-9-1 ? has-mir-9-2 (5q14.3 ) و (15q26.1 ) hsa-mir-9-3 نسخه برداری می شود. هایپرمتیلاسیون جزایر cpg واقع در جایگاه های کروموزومی اعضای خانواده mir-9 در موارد متعدد با متاستاز بعضی تومور ها ارتباط داشته است.کاهش ...
برای جداسازی انتخابی یون‌های اورانیم (VI) از آهن (III)، عملکرد سه غشای نانوفیلتر تجاری (2-NF-1 ،PES و 2-NF) از نظر میزان، شدت جریان عبوری و گزینش‌گری تحت شرایط عملیاتی مختلف ارزیابی شد. با افزایش pH از 3 تا 6، شدت جریان عبوری از غشاها کاهش و ضریب بازداری یون‌ها افزایش یافت. اورانیم دارای ضریب بازدارش کوچک‌تری نسبت به آهن بوده و غشاهای 2-PES و 1-NF در 4 pH بیشینه‌ی گزینش‌گری اورانیم نسبت به آهن...
Human T-lymphotropic virus type I (HTLV-1) is an endemic virus in Iran and other regions that is associated with multiple diseases including adult T-cell leukemia/ lymphoma and a chronic debilitating neuroinflammatory disease, HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). HAM/TSP is seen in approximately 2% of HTLV-1-infected people with symptoms such as back pain, weakne...
BACKGROUND AND PURPOSE The intraocular pressure (IOP)-lowering and side effects in response to different prostaglandin F2α analogues can be variable, but, the underlying basis for this difference remains unknown. This study investigated the differential changes of cellular proteins relevant to IOP-lowering effects of latanoprost and bimatoprost. METHODS The human T lymphoblast (MOLT-3) cell l...
BACKGROUND Pandemic strains of HIV-1 (group M) encode a total of nine structural (gag, pol, env), regulatory (rev, tat) and accessory (vif, vpr, vpu, nef) genes. However, some subtype A and C viruses exhibit an unusual gene arrangement in which the first exon of rev (rev1) and the vpu gene are placed in the same open reading frame. Although this rev1-vpu gene fusion is present in a considerable...
colorectal cancer (crc) is the second leading cause of cancer death. progress has been made in the development of chemotherapy for advanced crc. targeted therapies against vegf or egfr are now commonly used. however, many cases show that tolerance develops to such treatments; therefore, new strategies are required to replace or complement current therapies. nuclear factor-?b (nf-?b) transcripti...
Background & objectives: Nuclear Factor kappa B (NF-κB), a master switch transcription factor, plays a critical role in the progression and development of hyperglycemia-induced microangiopathy. Hyperglycemia activates NF-κB, and subsequently increases pro-inflammatory cytokines such as TNF-α, IL-6 and IL-1β leading to development of inflammation. Some new studies have revealed the involvement o...
