Glu-plasminogen, the native form of plasminogen, interacts in a specific and saturable manner with unstimulated human platelets, and the binding is enhanced fivefold by thrombin stimulation (Miles and Plow, 1985. J. Biol. Chem. 260:4303). This study characterizes the nature of the Glu-plasminogen binding sites by analyzing platelets deficient in selected proteins and functions. Platelets from p...
BACKGROUND Defects of integrin alpha(IIb)beta(3) are typical of Glanzmann's thrombasthenia, an inherited autosomal recessive bleeding disorder characterized by the failure of platelets to aggregate in response to all physiological agonists, but with no abnormalities in the number or size of platelets. Although large heterogeneity has been described for Glanzmann's thrombasthenia, no family has ...
Thrombin stimulation results in increased surface expression of endogeneous fibronectin and binding of plasma fibronectin to human platelets. Platelets of patients with Glanzmann's thrombasthenia, a bleeding disorder, exhibit reduced thrombin-induced platelet aggregation, little or no clot retraction, and abnormal platelet spreading on glass surfaces. Thrombin stimulation of patient platelets f...
A 20-year-old woman from a consanguineous family in the Hunan Province of the People‘s Republic of China was diagnosed as having Glanzmann‘s thrombasthenia based on (1) nearly a lifelong history of epistaxis, gum bleeding, petechiae, and purpura; (2) severe menorrhagia resulting in anemia and need for whole-blood transfusion; (3) normal coagulation assays; (4) prolonged bleeding time; (5) absen...
The general practitioner (GP) fundholding scheme was introduced as part of the Conservative governments 1991 National Health Service reforms and abolished by the Labour government in 1998. This paper contends that the scheme was introduced and abolished without policy-makers having any valid evidence of its effects. In particular, it focuses on the salient features of the decision to abolish. T...
Glanzmann thrombasthenia is an inherited bleeding disorder due to a functional reduction or absence of platelet GPIIb/IIIa (alphaIIbbeta3) integrin receptors. Based on a prolonged bleeding time and absence of platelet aggregation in response to physiologic agonists, a 55-year-old white man was diagnosed as having Glanzmann thrombasthenia. The patient's platelet fibrinogen level was approximatel...
