The metabolism of the complement proteins C3 and C4 was studied in patients with active and inactive systemic lupus erythematosus (SLE) using highly purified, functionally active preparations. Nine patients with active and eight with inactive SLE were examined and 11 control subjects. There was a significant difference in the level of double stranded DNA antibodies, immune complexes, and serum ...
Carbon isotope fractionation factors associated with the aerobic consumption of methane (C1), ethane (C2), propane (C3), and nbutane (C4) were determined from incubations of marine sediment collected from the Coal Oil Point hydrocarbon seep field, located offshore Santa Barbara, CA. Hydrogen isotope fractionation factors for C1, C2 and C3 were determined concurrently. Fresh sediment samples fro...
Background and Objectives: Complement proteins are some of the most important plasma proteins of the innate immune system. Impaired immune function is reported in subjects who are iron deficient, and there are documents that these patients are prone to infection. This study was conducted to show whether serum C3 and C4 complement change in adult nonpregnant female with iron deficient anemia or ...
Recurrent aphtus stomatitis (RAS) is an oral mucous lesion in patients with no other signs of disease. Investigators have always notified the role of immune system especially humoral immunity in aphtus immunopathogenesis. The aim of this case-controlled study was to measure amount of serum immonogiobulins (A,G,M) and complement component (C3 C4) in patients with RAS and to evaluate any relation...
سیستم کمپلمان از اجزاء اصلی سیستم دفاعی بدن بسیاری از موجودات میباشد. وجود این سیستم در موجودات متعددی تایید شده است اما در مورد مکانیسم های تنظیم بیان آن در سطح ژنومی برخی از موجودات اطلاعاتی وجود ندارد. در این مطالعه به بررسی ناحیه بالادستی ژن C3 از ماهی قزل آلا پرداخته ایم. بافتهای مختلف ماهی تهیه و DNA با روش تغییر یافته فنل-کلروفرم استخراج شد. به کمک پرایمرهای دجنره طراحی شده برای ناحیه با...
In the most common C4 pathway for carbon fixation, an NADP-malic enzyme (NADP-ME) decarboxylates malate in the chloroplasts of bundle sheath cells. Isoforms of plastidic NADP-ME are encoded by two genes in all species of Flaveria, including C3, C3-C4 intermediate, and C4 types. However, only one of these genes, ChlMe1, encodes the enzyme that functions in the C4 pathway. We compared the express...
Complement C3 and C4 play key roles in the main physiological activities of complement system, and their deficiencies or over-expression are associated with many clinical infectious or immunity diseases. A two-stage genome-wide association study (GWAS) was performed for serum levels of C3 and C4. The first stage was conducted in 1,999 healthy Chinese men, and the second stage was performed in a...
