میگوی ببری سبز خلیج فارس،p. semisulcatus یکی از گونه های مهم جنس penaeus در خلیج فارس است. براساس خصوصیات ریختی، زیرگونه جدیدی از آن، با نام p.(penaeus) semisulcatus persicus معرفی شده است. برای مطالـعه تفاوت های ژنتیکی میان گونه و زیر گونه مذکور، d-loop به عنوان نشانگر میتوکندریایی و its 2 به عنوان نشانگر ژنومیک مورد توجه قرار گرفتند. لذا 3 نمونه از گونه و 3 نمونه از زیر گونه از سواحل بوشهر جم...
The mixing behavior of the gas-liquid phase in three loop bioreactors was investigated. A gas-induced External Airlift Loop Bioreactor (EALB), a forced-liquid Vertical Tubular Loop Bioreactor (VTLB) and a forced-liquid Horizontal Tubular Loop Bioreactor (HTLB) were used for mixing studies as well as biomass production from natural gas. The effect of design parameters, riser to downcomer cro...

In the present study for evaluation of genetic variability within and between Iranian native fowls, thirty nine blood samples were randomly collected from native fowls breeding stations of west Azarbayjan, Khorasan, Fars, Mazandaran, Yazd and Esfahan provinces. Inorder to compare the obtained results with other Asian, African and European breeds the D-loop sequences of mtDNA taken from GenBan...
BACKGROUND Mitochondrial displacement loop (D-loop) is the hot spot for mitochondrial DNA (mtDNA) alterations which influence the generation of cellular reactive oxygen species (ROS). Association of D-loop alterations with breast cancer has been reported in few ethnic groups; however none of the reports were documented from Indian subcontinent. METHODOLOGY We screened the entire mitochondrial...
DNA methylation occurs in the displacement loop (D-loop) region of mammals; however, D-loop regions of certain tumor tissue types were found to be de‑methylated. Whether hypomethylation of the D‑loop region is involved in the regulation of the mitochondrial DNA (mtDNA) copy number and nicotinamide adenine dinucleotide subunit 2 (ND‑2) expressions in colorectal cancer has remained elusive. In th...
the mitochondrial dna (mtdna) mutations in mitochondrial coding and non coding regions seem to be important in carcinogenesis. the aim of this investigation was to evaluate coding region (mt-trnaphe and trnapro) and non-coding sequence, mitochondrial displacement loop (mtdna d-loop), in the cancerous and non-cancerous lesions of iranian patients with breast cancer (bc). genomic dna was extracte...
Many copies of mammalian mitochondrial DNA contain a short triple-stranded region, or displacement loop (D-loop), in the major noncoding region. In the 35 years since their discovery, no function has been assigned to mitochondrial D-loops. We purified mitochondrial nucleoprotein complexes from rat liver and identified a previously uncharacterized protein, ATAD3p. Localization studies suggested ...
هدف از این پژوهش ارزیابی تنوع ژنتیکی نژادهای مختلف ماهی قزل آلای رنگین کمان (ایرانی، فرانسوی و دانمارکی) با استفاده از جایگاه های d-loop و سیتوکرم b dna میتوکندریایی بوده است. dna به روش فنل-کلروفرم از بافت باله ی دمی 135 قطعه ماهی استخراج و واکنش زنجیره ای پلی مراز (pcr) جهت تکثیر یک قطعه 986 جفت بازی از ناحیه ی d-loop و یک قطعه 974 جفت بازی از ژن سیتوکرم b دی. ان. ای میتوکندریایی و با استفاده...
Intraspecific sequence variation in the D-loop region of mtDNA in white sturgeon (Acipenser transmontanus), a relict North American fish species, was examined in 27 individuals from populations of the Columbia and Fraser rivers. Thirty-three varied nucleotide positions were present in a 462-nucleotide D-loop sequence, amplified using the polymerase chain reaction. Bootstrapped neighbor-joining ...
