OBJECTIVE The relationship of Gantzer muscle to the median and anterior interosseous nerve is debated. METHODS Ìn an anatomical study with 80 limbs from 40 cadavers the incidence, origin, insertion, nerve supply and relations of Gantzer muscle have been documented. RESULTS The muscle was found in 54 forearms (68% of limbs) and was supplied by the anterior interosseous nerve. It arose from t...
Transposable elements (i.e. insertion sequences and transposons) are components of nearly all bacterial genomes. The majority of these elements have been identified as a result of various sequencing projects. However, in most cases, their activity was not experimentally confirmed. For this reason several strategies have been developed that allow direct cloning and identification of functional t...
Heterochromatin contains a significant part of nuclear DNA. Little is known about the mechanisms that govern heterochromatic DNA stability. We show here that in the yeast Saccharomyces cerevisiae (i) DNA mismatch repair (MMR) is required for the maintenance of heterochromatic DNA stability, (ii) MutLα (Mlh1-Pms1 heterodimer), MutSα (Msh2-Msh6 heterodimer), MutSβ (Msh2-Msh3 heterodimer), and Exo...
مقدمه و هدف: نیکوتین ترکیب اصلی سیگار محسوب می شود که می تواند به راحتی از سد خونی- جفتی عبور کند و در اندام های درحال تکوین جنین تجمع یابد. بعلاوه نیکوتین در دوران شیردهی وارد شیر می شود و نوزاد را تحت تأثیر قرار می دهد. مطالعات نشان داده است که کلاژن iv یکی از مهمترین اجزاء غشای پایه ی عروق در اندام های مختلف جنین از جمله مغز محسوب می شود. در این مطالعه تأثیر تجویز نیکوتین مادری روی کلاژن iv ...
نقش استرس در شروع و تشدید اختلالات روانی، سال هاست که هدف بسیاری از تحقیقات بوده است. از این رو محور چهار dsm-iv-tr به این نوع حوادث، اختصاص داده شده است. با این وجود، مسائل ذکر شده در این محور، اولاً بسیار کلی است، ثانیاً ممکن است قابل تعمیم به تمام فرهن گها نباشد. در این تحقیق به روش نمونه گیری تصادفی ساده، پرسش نامه ادراک حوادث استرس آور در میان گروهی از دانشجویان دانشگاه های شهرستان اهواز، تو...
Twelve independent TnlO insertion mutants of Escherichia coli K12 were isolated that were defective in the synthesis of enterobacterial common antigen (ECA). The mutants were identified by screening a random pool of TnlO insertion mutants for their ECA phenotype using a colony-immunoblot assay. All 12 of the TnlO insertion mutants were found to be located in the chromosomal region of the rff-rf...
BACKGROUND Capsular contracture remains a common and dreaded complication of breast augmentation. The etiology of capsular contracture is believed to be multi-factorial, and its causes may include biofilm formation due to implant/pocket contamination with skin flora. It has been shown that insertion funnel use reduces skin contact and potential contamination by 27-fold in a cadaver model. After...
nephritis remains an important problem in patients with systemic lupus erythematosus (sle). we conducted retrospective study to evaluate the efficiency of intravenous pulse cyclophosphamide in lupus nephritis: from 1983 to 1993, we reviewed 133 patients with biopsy proven lupus nephritis, 47 of them excluded because of short period of follow-up or defective laboratory data. eighty six patients ...
BACKGROUND Ultrasound guidance for continuous femoral perineural catheters may be supplemented by electrical stimulation through a needle or through a stimulating catheter. The authors tested the primary hypothesis that ultrasound guidance alone is noninferior on both postoperative pain scores and opioid requirement and superior on at least one of the two. Second, the authors compared all inter...
