background: acanthamoeba keratitis develops by pathogenic acanthamoeba such as a. palestinensis . indeed this species is one of the known causative agents of amoebic keratitis in iran. mannose binding protein (mbp) is the main pathogenicity factors for developing this sight threatening disease. we aimed to characterize mbp gene in pathogenic acanthamoeba isolates such as a. palestinensis . m...
the sucrose non-fermenting 1-related protein kinase 2 (snrk2) family members are plant unique serine/threonine kinases which play a key role in cellular signaling in response to abiotic stresses. the three snrk2 members including srk2d, srk2i and srk2e are known to phosphorylate major abscisic acid (aba) responsive transcription factors, abf2 and abf4, involved in an aba-dependent stress signal...
Quantitative determinations were carried out of the relative reaction rates of several nitrogen mustards at various guanine-N7 positions in DNA fragments of known sequence. The findings suggest structural hypotheses of the origins of the reaction selectivities. End-labeled DNA fragments were reacted with nitrogen mustards, and the guanine-N7 alkylation sites were analyzed by gel electrophoresis...
Background: In 10-30% of the cases with sarcoidosis, skin lesions appear solely without any systemic signs or symptoms. BTNL2 gene, which is a member of the immunoglobulin gene super family and is associated with CD86 and CD80 co-stimulatory receptors, is identified to play an important role in the establishment of sarcoidosis. We aimed to evaluate the role of this gene in patients with skin sa...
چکیده : * در یک واکنش تک ظرفی و با استفاده از واکنش آلدهید های آروماتیک و 3- متیل 1- فنیل پیرازولین-5- ان با نسبت مولی 1:1، ساختارهای هتروسیکل پیرازول سنتز شد. از مزایای آن، انجام واکنش در دمای اتاق، عدم نیاز به کاتالیزور، بازده بالای واکنش، استفاده از آب بعنوان حلال سبز و بی خطر به جای حلال های آلی وسمی می باشد . * توانستیم با استفاده از ملدرام اسید ومشتقات 2- هیدروکسی بنزآلدهید، ترکی...
paris polyphylla smith var. yunnanensis (liliaceae) is an important traditional medicinal plant of the yunnan province in china. however, the genomic information regarding this plant is limited. to further understand its molecular background, we conducted illumina hiseq 2000 second-generation sequencing of this plant species. approximately 30,198,679 reads with an average length of 202 bases we...
bioinformatics, through the sequencing of the full genomes for many species, is increasingly relying on efficient global alignment tools exhibiting both high sensitivity and specificity. many computational algorithms have been applied for solving the sequence alignment problem. dynamic programming, statistical methods, approximation and heuristic algorithms are the most common methods applied t...
Background: Thrombopoietin (TPO) is an important cytokine that has a critical role in regulating hematopoietic stem cells (HSCs) proliferation and megakaryocyte differentiation. Because of scares amount of this protein in human plasma, in many biotechnological centers around the world, recombinant production of this protein has been carried out. This study was aiming to gene cloning and express...
Background and Objective: Choline is a precursor for the synthesis of the most important cholinergic neurotransmitter that induce the release of calcium from sarcoplasmic reticulum that finally leads to muscle contraction. The purpose of the current study was to survey the effect of one week choline supplementation on memory, reaction time, throwing darts and balance in recreationally active me...
