زمینه و هدف: ریزنشت به عنوان معیاری جهت ارزیابی موفقیت هر ماده ترمیمی مطرح بوده و دستیابی به سیل مناسب نیز در مارجین ها مشکلات خاص خود را دارد، به ویژه در مارجین های عاجی بسیار مشکل تر از مینای دندان می باشد. تحقیق حاضر با هدف مقایسه ریزنشت در مارجین های مینایی و عاجی حفره های کلاس v در دو نوع gi با استفاده از دو نوع باندینگ مختلف self etch انجام شد. روش بررسی: در سطوح باکال و لینگوال 40 دندان ...
چکید ه سابقه و هدف هموفیلی b یک بیماری وابسته به جنس مغلوب است که در اثر کاهش مقدار و یا نقص عملکرد فاکتور ix انعقادی رخ می دهد. ژن فاکتور ix انعقادی به طول 34 کیلو باز، دارای 8 اگزون است. جهش در نواحی مختلف ژن فاکتور ix انعقادی سبب نقص در پروتئین ix انعقادی و بیماری هموفیلی b می گردد. هدف از این مطالعه تعیین جهش در ژن فاکتور ix انعقادی بیماران مبتلا به هموفیلی b در استان اصفهان و یافتن ا...
many investigations have proved relations between abo blood groups with some diseases and factor viii and von willebrand level in plasma. in this study we investigated a relation between abo blood groups and factor viii and ix inhibitors in 102 patients with haemophilia a and 48 patients with haemophilia b. the assay of inhibitor was done by bethesda method. there were no relation between abo b...
Background: Hemophilia B is an X-linked recessive coagulation disorder caused by factor IX deficiency. Analysis of factor IX gene polymorphisms is considered the best approach for prenatal diagnosis and carrier detection of hemophilia B where the identification of gene mutation is not easily possible. Objective: To study the frequency of three factor IX-linked restriction fragment length polym...
Hemophilia B is an X-chromosomal recessive disease due to deficiency of coagulation factor IX. Three monoclonal antibodies against factor IX were prepared and used to develop immunoradiometric assays (IRMAs) of factor IX antigen (IX-Ag). IX-Ag was measured in 65 normal individuals with one IRMA based on polyclonal anti-IX antibodies and two IRMAs based on three monoclonal anti-IX antibodies. On...
A series of non-cyclic polyethers with different end groups and chain length were used for the extraction of lithium salt from aqueous into various organic phases viz. Chloroform, Carbon tetrachloride, 1,2-dichloroethane, to study the influence of structural variations within the extractant molecule upon the extraction selectivity and efficiency. The ionophores used were viz. DEG (I), DEGDME (I...
Background: Bernard-Soulier syndrome is a rare inherited bleeding disease caused by quantitative or qualitative defect of GPIb/IX/V, a platelet complex that binds the Von Willebrand factor. The expression of GPIb-IX-V complex can be evaluated by flow cytometry and confirmed by the absence of ristocetin-induced platelet aggregation in platelet-rich plasma. The main aim of the present study was t...

بررسی تنوع ژنتیکی مارکر rs438601در جمعیت اصفهان: یک مارکر آگاهی‌دهنده در تشخیص‌های مولکولی هموفیلی B
Introduction: Hemophilia B is an X-linked recessive genetic disease caused by mutations in the coagulation Factor IX gene. Mutations in the Factor IX gene result in dysfunction or deficiency of coagulation factor of IX. Direct mutation analysis involves the ideal method for molecular diagnosis of the disease. However, due to the high number of identified mutations in the gen, the lack of a comm...
To determine the functional role of the metal-dependent conformational changes in Factor IX, two populations of conformation-specific anti-Factor IX antibodies were prepared. Anti-Factor IX X Mg(II) antibodies bind to Factor IX in the presence of Mg(II) and other metal ions, but not in the absence of metal ions. Anti-Factor IX X Ca(II)-specific antibodies bind to Factor IX in the presence of Ca...
