A new case of combined factor V-VIII deficiency is reported with in vitro studies of factors V and VIII activation by thrombin. The normal activation of factors V and VIII demonstrated in the patient's plasma and the equivalent levels of factor VIII coagulant activity and coagulant antigen support the hypothesis that a quantitative rather than qualitative defect in factors V and VIII is present...

The aim of this study was to identify hereditary and acquired risk-factors as they are related to the occurrence of stroke in children. We identified 21 children with stroke. A search of the Factor V Leiden mutation, the Factor II G20210A variant, and the thermolabile variant of methylenetetrahydrofolate reductase was performed in patients and in a control group (n = 115). We identified risk fa...

Native bovine factor V exists in three forms of differing molecular size, the oligomeric interconvertible forms A and C and a phospholipid-containing complex designated form L. Thrombin increases the activity of form A to a greater extent than form L and does not alter the activity of form C. Thrombin-activated form A and form C function as potent inhibitors of thrombin activation of form A but...

It is shown that in a mortel with a regular long range interaction, a 2D fermion gas at half filling of the band is a Luttinger Liquid. It is found that under certain conditions the jump in the momentum distribution of such a gas at the Fermi surface deperlds on the filling factor v in trie form +~ ((2v -1)/A(~°,
