The present invention provides methods of determining a human subject's risk for venous thrombosis based on the finding that venous thrombosis patients have significantly lower levels of large HDL particles, HDL-cholesterol and apolipoprotein Al and higher levels of small LDL particles, LDL-cholesterol and apolipoprotein B. Genotyping showed that venous thrombosis patients differed significantly from controls in CETP genotype and that the CETP genotypes found in subjects with VTE are linked to elevated CETP mass and activity. Methods for determining the level of lipids or lipoproteins in plasma or serum samples to determine risk for venous thrombosis are provided. Methods for reducing the risk of venous thrombosis are also provided.
摘要:
An optical recording medium including a substrate on which a first protective layer, an interface layer, a phase change recording layer, a second protective layer, an optional third protective layer (anti-sulfuration layer), and a reflective layer are accumulated in this order. The first protective layer contains a mixture of ZnS and SiO2 The interface layer contains a material containing Si and O. The phase change recording layer contains Sn, Sb, Ga, and Ge. In addition, the content of Si and O in the interface layer is 10 to 60% greater than a content of Si and O in the first protective layer.

It is an object of the present invention to provide a phase-change information recording medium, and the like, which is easy to perform initial crystallization, exhibits good recording sensitivity at a linear velocity as high as 10 double speeds or more with as much capacity as DVD-ROM, is capable of overwrite recording and has good storage reliability. For this purpose, the phase-change information recording medium comprises a substrate and at least a first protective layer, a phase-change recording layer, a second protective layer, and a reflective layer disposed on the substrate in one of this sequence and reverse sequence wherein the phase-change recording layer comprises a composition expressed by SnαSbβGaγGeδTeεXζ (In this regard, X represents at lease one element selected from Ag, Zn, In and Cu. α, β, γ, δ, ε and ζ represent composition ratio (atomic percent) of each element and are expressed as 5≦α≦25, 40≦β≦91, 2≦γ≦20, 2≦δ≦20, 0≦ε≦10, 0≦ζ≦10 and α+β+γ+δ+ε+ζ=100).
摘要:
A first transmitter outputs a request signal requesting a response to a mobile device toward an area including a driver's seat and its neighborhood, and a second transmitter outputs this request signal toward an area covering the entire vehicle. The mobile device transmits a response signal to a receiver if receiving the request signal transmitted from the first or second transmitter. The controller detects the position of the mobile device based on a communication result between the mobile device and the receiver in response to the request signals transmitted from the first and second transmitters.
