1 Innitesimal Homotopy The innitesimal homotopy relation reads: LX ω = d (iX ω) + iX (dω) Using this, we wish to evaluate LX (dω) and d (LX ω). First: LX dω = d (iX dω) + iX ddω However, since ddω = d 2 ω = 0, this leaves us with: LX dω = d (iX dω) On the other hand, we have: d (LX ω) = d (d (iX ω) + iX dω) = d 2 (iX ω) + d (iX dω) Once again, d 2 (iX ω) = 0; this leave us with: d (LX ω) = d (i...
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 ...
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...
سابقه و هدف : اختلالات قلبی-عروقی یکی از علل مهم مرگ و میر در بیماران دیابتی شناخته شده اند. مطالعات متعددی نشان می دهد که اختلالات قلبی-عروقی در بیماران دیابتی به دنبال تشکیل ترومبوز های کوچک در درون عروق ایجاد می گردند. مطالعات پیشین ما افزایش معنی دار برخی از فاکتور های انعقادی، کاهش کارایی آبشار های انعقادی و طولانی شدن زمان انعقاد در این بیماران را نشان می دهد. مطالعه حاضر به منظور مطالعه ...

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...
