Fv-4 is a mouse gene that dominantly confers resistance to infection by ecotropic murine leukemia virus (MuLV). We previously demonstrated that mixed radiation bone marrow chimeras containing Fv-4r-bearing BALB/c-Fv-4Wr (C4W) bone marrow and Fv-4r-bearing C3H/He (C3H) bone marrow grafted into C3H recipient mice (C4W+C3H-->C3H) were resistant to Friend leukemia virus (FLV)-induced leukemogenesis...

BACKGROUND It was reported that Glutathione S-transferase (GST) gene polymorphism and fruit and vegetable (FV) intake were associated with body antioxidant capacity. The oxidative/anti-oxidative imbalance played an important role in the pathogenesis of AD. However, the association of GST genotype, dietary FV consumption with body antioxidant biomarkers and cognitive function in the elderly is n...

Okra is a vegetable crop adapted to summer temperatures, but heat stress has been shown reduce its growth and productivity. We measured physiological traits of 104 okra genotypes in response high temperature, augmented by the molecular characterization selected identify parents for crossing. Genotypes were exposed short shock (45 °C, 4 h) controlled environment, followed assessment chlorophyll ...

BACKGROUND Children consume restaurant-prepared foods at high rates, suggesting that interventions and policies targeting consumption of these foods have the potential to improve diet quality and attenuate excess energy intake. One approach to encouraging healthier dietary intake in restaurants is to offer fruits and vegetables (FV) as side dishes, as opposed to traditional, energy-dense accomp...

Ecological studies are essential for understanding the environment-diet relationship. The purpose of this study was to describe environmental conditions and their relationship with fruit and vegetable (FV) consumption among Brazilian public health service users in the city of Belo Horizonte. We evaluated food stores contained within 1600 m buffer zones at 18 Health Academy Programme sites, from...

Coagulation factor V (FV) promotes inactivation of activated factor VIII (FVIIIa) by activated protein C (APC) and protein S. Loss of this APC cofactor activity is proposed to be partially responsible for the APC resistance phenotype of FV Leiden . However, FVIIIa loses activity rapidly due to dissociation of the A2 domain, and this may be the primary mechanism of FVIIIa inactivation. APC/prote...

Thromb Haemost 2006; 95: 896–7 The clotting factor now known as factorV (FV) was first described in 1908 (1), and a deficiency of this factor was first described by Owren as parahaemophilia in 1947 (2). FV is predominantly produced in the liver and to a lesser degree by the megakaryocytes. Circa 80% of FV circulates in the plasma while 20% is stored in platelets. Following α-granule release upo...

Blood coagulation FV (Factor V) is activated by thrombin-mediated excision of the B domain, resulting in a non-covalent heterodimer, FVa (activated FV). Previous studies implicated Glu96, Asp102 and Asp111 in the essential Ca2+-dependent FVa subunit interaction. In the present study, FV E96A, D102A and D111A were purified and evaluated for function, subunit dissociation and metal ion binding. C...

Inherited deficiencies of plasma proteins involved in blood coagulation generally lead to lifelong bleeding disorders. The severity of these disorders is generally inversely proportional to the degree of factor deficiency. Among all the autosomal recessive rare bleeding disorders, which include afibrinogenaemia, factor (F) II, FV, FV + VIII, FVII, FX, FXI, FXIII, the combined deficiency of coag...
