Thirteen of 14 tumor cells or tumor cell lines of guinea pig, mouse, and human origin spontaneously shed procoagulant activity in short-term (4 or 14 to 22 hr) tissue culture under conditions of high cell viability. This released procoagulant activity was pelletable in the ultracentrifuge and was associated with plasma membrane-derived vesicles as determined by transmission electron microscopy ...

We analyzed the mutations in patients from 10 Polish kindreds with a bleeding diathesis due to factor VII deficiency. Patients from eight families had plasma levels of factor VII coagulant activity (VII:C) and factor VII antigen (VII:Ag) that were less than 4% of normal. The coding sequence of the factor VII gene was amplified from genomic DNA by polymerase chain reaction (PCR). Sequencing demo...

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...

Blood coagulation Factor M was purified 100,000fold from fresh frozen human plasma to apparent homogeneity with a yield of 30% based on coagulation assay. The molecular weight estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis was 48,000. Factor VI1 is composed of a single polypeptide chain with the NHz-terminal sequence Ala-Asn-AlaPhe-Leu-(G1a)-(Gla)-Leu-(Arg)-Pro. It is co...

The aim of the present study was to investigate the effects of stearic acid-, oleic acid- and linoleic acid-rich meals on postprandial haemostasis in young healthy volunteers whose background diets had been controlled for 14 d in a residential study. Six healthy male volunteers were assigned randomly to consume diets rich in stearic acid, oleic acid or linoleic acid for 14 d. On day 15, plasma ...

Although numerous cross-sectional studies have identified possible determinants of plasma fibrinogen and factor VII levels, few prospective studies exist. We assessed the longitudinal relation of changes in fibrinogen and factor VII over 6 years with changes to other cardiovascular risk factors in a sample of 440 men and 549 women from the Atherosclerosis Risk in Communities (ARIC) study. Fibri...

Background: Normal pregnancy has been associated with alteration of the haemostatic system which has been linked to increased risk of thromboembolism. The study determined the haemostatic parameters in pregnant women in Kano, North-West Nigeria. Materials and Methods: One hundred and fifty pregnant women, aged 17-40 years and 100 age-matched nonpregnant women were enrolled for the study between...
