Background: We performed this study in order to investigate the role of chronic endometritis (CE) in unexplained recurrent spontaneous abortion (RSA) and to determine the correlation between hysteroscopic and histologic findings of CE in patients with unexplained RSA. We also tried to find out the relation between CE and primary vs. secondary RSA. Materials and Methods: One hundred and forty-two ...
Background: It is unclear whether hemiarthroplasty (HA) or reverse shoulder arthroplasty (RS) are superior for patientswith cuff tear arthropathy (CTA) and preserved preoperative motion (elevation >90˚).Methods: This was a retrospective, single institution study. Patients who underwent RSA or HA for CTA were included ifthey had preserved preoperative motion with a minimum of 2...
Introduction: Immunological processes play an important role in recurrent spontaneous abortion(RSA). According to studies, T lymphocytes and natural killer cells(NK cells) are two effective cell groups in RSA. The aim of this study was to study the percentage and absolute number of natural killer(NK) cells in women with RSA of unknown etiology. Methods: A total of 24 women with history of recu...
Background Approximately 2-4% of all women have recurrent spontaneous abortion (RSA); however, the cause is determined in only 50% of cases. Recent studies have shown an association between thyroid autoantibodies as a sign of thyroid autoimmunity and abortion. The aim of the present study was to determine whether circulating anti-thyroid peroxidase (anti-TPO) was associated with RSA. MaterialsA...
in addition to ultrasonographic monitoring of folliculogenesis, urinary luteinizing hormone testing, luteal phase endometrial biopsy, serum antiphospholipid antibodies, etc., immunologic tests are recently being used to evaluate reproductive disorders. in this study, sharing of hla-a, b, c and dr antigens and the presence of antipaternal cytotoxic antibody (apca) was assessed using microcytotox...
Background: The aim of this study was to examine the possible relationship between sperm DNA integrity and chromatin packaging evaluated by cytochemical assays, traditional sperm parameters and recurrent spontaneous abortion (RSA) of unknown origin. Materials and Methods: In this cohort study, 40 couples with a history of RSA and 40 couples with proven fertility were considered as case and cont...
در این پایان نامه ابتدا به معرفی سیستم رمزی rsa می پردازیم. این سیستم رمزنگاری با کلید عمومی اولین بار در میانه های سال 1970 مورد توجه قرار گرفت و سیستم rsa در سال 1978 مطرح شد به دلیل سادگی و همچنین امنیت بالای این سیستم به محبوبترین سیستم رمزنگاری باکلید عمومی تبدیل شد.سپس روی دستگاه معادلات پیمانه ای یک متغیره و چگونگی حل پذیری آن ها بحث خواهیم کرد. همچنین دستگاه معادلات پیمانه ای وابسته به ...
Low resting respiratory sinus arrhythmia (RSA), and to a lesser extent excessive RSA reactivity to emotion evocation, are observed in many psychiatric disorders characterized by emotion dysregulation, including syndromes spanning the internalizing and externalizing spectra, and other conditions such as nonsuicidal self-injury. Nevertheless, some inconsistencies exist. For example, null outcomes...
Background: Recurrent spontaneous abortion (RSA) and in vitro fertilization (IVF) failure with unknown causes are the controversial issues that are probably related to the immune system. Objective: To compare circulating NK cells expressing activation and inhibition surface markers between patients with RSA and IVF failure with those of healthy multiparous and successful IVF control women, resp...
زمینه و هدف: امروزه یافتن بهترین روش بازیافت برای ورزشکاران اهمیت زیادی پیدا کرده است. هدف تحقیق حاضر بررسی آثار تکرار فعالیتهای سرعتی (RSA) و 12 دقیقه غوطهوری در آب سرد (CWI) 14 درجه سانتیگراد بلافاصله بعد از RSA، بر مقادیر سرمی شاخصهای التهابی خستگی اینترلوکین-6 (IL-6) و عامل نکروز تومور آلفا (TNF-α) در مردان فعال بود. روش تحقیق: روش تحقیق نیمه تجربی و جامعه آماری مردان فعال با دامنه سنی ...
