The case for a generic phytosanitary irradiation dose of 400 Gy for Lepidoptera that infest shipped commodities as pupae.

The pros and cons of a generic phytosanitary irradiation dose against all Lepidoptera pupae on all commodities are discussed. The measure of efficacy is to prevent the F1 generation from hatching (F1 egg hatch) when late pupae are irradiated. More data exist for this measure than for others studied, and it is also commercially tenable (i.

Factor VLeiden inhibits fibrinolysis in vivo.

Background: Factor V(Leiden) (fV(Leiden)) predisposes to thrombosis by enhancing thrombin formation. This study tested the hypothesis that fV(Leiden) inhibits fibrinolysis in vivo.

Methods And Results: Radiolabeled clots were injected into the jugular veins of wild-type mice and mice heterozygous (fV(+/Q)) or homozygous (fV(Q/Q)) for fV(Leiden).

Endogenous vitronectin and plasminogen activator inhibitor-1 promote neointima formation in murine carotid arteries.

We examined the roles of vitronectin and plasminogen activator inhibitor-1 (PAI-1) in neointima development. Neointima formation after carotid artery ligation or chemical injury was significantly greater in wild-type mice than in vitronectin-deficient (Vn(-/-)) mice. Vascular smooth muscle cell (VSMC) proliferation did not differ between groups, suggesting that vitronectin promoted neointima development by enhancing VSMC migration.
