Mice doubly heterozygous for a modified tissue factor pathway inhibitor (TFPI) allele (tfpi delta) lacking its Kunitz-type domain-1 (TFPI+/delta) and for a deficiency of the factor VII gene (FVII+/-) were mated to generate 309 postnatal and 205 embryonic day 17.5 (E17. 5) offspring having all the predicted genotypic combinations. Progeny singly homozygous for the tfpidelta modification but with...

Combined factor V and factor VIII deficiency (F5F8D) is a rare, autosomal recessive congenital bleeding disorder with a prevalence of 1:1,000,000. Individuals present with a variable clinical bleeding phenotype, elevated prothrombin time (PT) and partial thromboplastin time (PTT), and plasma levels of factor V and VIII of 5–30%. Mutations in 2 proteins, LMAN1 and MCFD, required for concurrent t...

To analyze inherited antithrombin deficiency as a risk factor for venous thromboembolism in various conditions with regard to the presence or absence of additional genetic or acquired risk factors, we compared 48 antithrombin-deficient individuals with 44 nondeficient individuals of 14 selected families with inherited antithrombin deficiency. The incidence of venous thromboembolism for antithro...

Venous intestinal ischemia is a relatively rare disease, which has some predisposing factor up to 80 % of cases. These factors may be temporary or permanent. Cancer, immobilization, trauma, intraabdominal infections, or oral contraceptives are temporary factors. Paroxysmal nocturnal hemoglobinuria and hypercoagulability states as factor V Leiden, G20210A mutation in prothrombin gene, C677T meth...

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...

PURPOSE Elevated lipoprotein (a) [LP (a)] concentrations are independent risk factors of coronary heart disease or stroke in young adults. To clarify its role in childhood thromboembolism, Lp (a) was measured in 72 children with thromboembolism. METHODS In addition to Lp (a), defects of the protein C anticoagulant system, antithrombin, and antiphospholipid antibodies were investigated in chil...

Quantifying soil organic carbon (SOC) decomposition under warming is critical to predict carbon-climate feedbacks. According to the substrate regulating principle, SOC decomposition would decrease as labile SOC declines under field warming, but observations of SOC decomposition under warming do not always support this prediction. This discrepancy could result from varying changes in SOC compone...

There is a long-standing interest in behavioural ecology, exploring the causes and correlates of consistent individual differences in mean behavioural traits ('personality') and the response to the environment ('plasticity'). Recently, it has been observed that individuals also consistently differ in their residual intraindividual variability (rIIV). This variation will probably have broad biol...
