Aim and Background: Histones are replaced by protamines to package sperm head DNA during mammalian spermatogenesis. Protamine genes variation cause sperm DNA damage and is affect infertility in men. Therefore this study aim was investigation on association of two rs737008 in PRM1 gene and rs4780356 in PRM2 gene polymorphisms with azoospermia and oligospermia in Iranian idiopathic infertile men....
Background: Chlamydia Trachomatis (CT) is an obligate intracellular bacteria, that requires living cells to replicate itself and is responsible for lower urinary tract disease in men and women. It can cause urethritis, epididymitis, orchitis and complications such as chronic prostatitis in men. Chlamydia infections may also directly affect male fertility by damaging the sperm, because sperm par...
background and objective: to estimate the risk of human papilloma virus (hpv) infection for cervical malignancies, we conducted a case-control study in southern iran (hormozgan province). materials and methods: for this purpose,52 paraffin embedded blocks with exact diagnosis of cervical carcinoma(50 carcinomas and 2 carcinomas in situ) from 2001 to 2006 and 52 praffin embedded blocks of cervic...
sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
Background: Diabetes mellitus, a condition of chronic hyperglycemia, represents one of the greatest concerns to modern global health. Diabetes is a serious metabolic disorders with numerous complications. It is well known that, elevation of blood glucose levels leads to structural and functional changes in various target tissues and organs. The objective of the present study was to verify if th...
Purpose: The aim of this study was to investigate effects of insulin and ascorbic acid on rate of Caspase – 3 activity and DNA Laddering in hippocampus of STZ-induced diabetic rats.Materials and Methods: Thirty male Wistar rats in five groups, 6 in each group: one control group (group C) and four diabetic groups [diabetic control (group D), treatment with insulin (group I), with ascorbic acid (...
background and objectives: dna ladder contains dna fragments of different length but with known size, used to determine the size of unknown dna molecules. different dna ladders are available for expected dna length. conserved sequences were selected for design of primers to generate dna fragments of known specific size. materials and methods: in this study, we describe a method by which dna lad...
Background: Various studies proposed virus infection is to be a possible cause of human breast cancer. However, the data argue the association between virus and cancer are inconsistent. This study was conducted to detect whether HPV-DNA is present in tissue samples of breast cancer in Isfahan province. Materials and Methods: Paraffin embedded formalin fixed specimens were prepared from 40 brea...
Background: Single nucleotide polymorphisms in 8-oxoguanine DNA glycosylase-1 (OGG1) gene modulates DNA repair capacity and functions as one of the first lines of protective mechanisms against 8-hydroxy-2’-deoxyguanosine (8-OHdG) mutagenicity. OGG1-Cys326 gene polymorphism may decrease DNA repair function, causing oxidative stress due to higher oxidative DNA damage. The main purpose of this stu...
DNA is the ultimate molecule that encodes life through genes. Genes positioned along meter-long have to be expressed at right time and in amount via strict regulatory processes. Regulation of a gene starts with binding DNA-binding protein known as transcription factor (TF) target element double-stranded molecule. Often, TFs attach sequence-specific manner can motifs various lengths, yet some al...
