Quantitation of activated factor VII levels in plasma using a tissue factor mutant selectively deficient in promoting factor VII activation.
Although the majority of factor VII (FVII) circulates in the zymogen form, low levels of activated factor VII (FVIIa) have been postulated to exist in plasma and to serve a priming function for triggering of the clotting cascade. However, direct measurement of plasma FVIIa has not previously been possible. We have quantified plasma FVIIa levels using a novel, highly sensitive assay that is free...
متن کاملComplement activation in factor D-deficient mice.
To assess the contribution of the alternative pathway in complement activation and host defense and its possible role in the regulation of systemic energy balance in vivo, factor D-deficient mice were generated by gene targeting. The mutant mice have no apparent abnormality in development and their body weights are similar to those of factor D-sufficient littermates. Complement activation could...
متن کاملCharacterization of tumor necrosis factor-deficient mice.
Although tumor necrosis factor (TNF) initially came to prominence because of its anti-tumor activity, most attention is now focused on its proinflammatory actions. TNF appears to play a critical role in both early and late events involved in inflammation, from localizing the noxious agent and amplifying the cellular and mediator responses at the local site and systemically, to editing (e.g., ap...
متن کاملJaundice and factor VII deficiency in newborn
Resistance to thyroid hormone is an uncommon condition. We report the clinical and laboratory findings of a case with both resistance to thyroid hormone and, a reduced capacity to produce and respond to thyroid hormone. RTH is a disorder characterized by elevated circulating thyroid hormones, state of non-suppressed pituitary TSH secretion and refractoriness to hormone action in peripheral tiss...
متن کاملPreparation of factor VII concentrate using CNBr-activated
Background: Factor VII concentrates are used in patients with congenital or acquired factor VII deficiency or treatment of hemophilia patients with inhibitors. In this research, immunoaffinity chromatography was used to purify factor VII from prothrombin complex (Prothrombin-Proconvertin-Stuart Factor-Antihemophilic Factor B or PPSB) which contains coagulation factors II, VII, IX and X. The a...
