PURPOSE Dual-energy CT imaging tends to suffer from much lower signal-to-noise ratio than single-energy CT. In this paper, we propose an improved anticorrelated noise reduction (ACNR) method without causing cross-contamination artifacts. METHODS The proposed algorithm diffuses both basis material density images (e.g., water and iodine) at the same time using a novel correlated diffusion algor...

To examine the effects of dietary fat intake on breast cancer risk, we are conducting a randomized trial of dietary intervention in women with extensive areas of radiologically dense breast tissue on mammography, a risk factor for breast cancer. Early results show that after 2 years on a low-fat, high-carbohydrate diet there is a significant reduction in area of density, particularly in women g...

Studies performed in vivo have been controversial regarding the implication of human apolipoprotein (apo)A-II in the atherogenic process. Expression of human apoA-II in transgenic mice fed a chow diet leads to (1) a bimodal distribution of high density lipoprotein (HDL) size as in humans, (2) a reduction in total cholesterol concentration that is mainly due to a reduction in non-HDL cholesterol...

background: previous studies have demonstrated that nuts consumption have beneficial effects on serum lipid profiles in hyperlipidemic or normolipidemic subjects. however, similar studies in diabetes field are quite rare. so, we aimed to investigate the effects of hazelnut consumption on fasting blood sugar (fbs) and lipid profiles in patients with type 2 diabetes. materials and methods: an 8 â...

one of the indicators of management and sustainability control of forest resources is the definition deforestation and degradation types. these factors hazard quantitative and qualitative of the iranian forests. in this study with integrated approach, different forms of forest degradation identified in the forest areas with a reviews of library resources and then investigation the degree of sta...

different methods have been evaluated for manufacturing the porous ti6al4v alloys according todecreasing stress shielding phenomenon and increasing mechanical compatibility between themetallic components and the host tissue. for this purpose, in this work ti6al4v alloy chips werepressed under 400 mpa pressure and then samples were categorized and heated into two groups at1000 and 1150℃ under a ...

The den use of possums (Trichosurus vulpecula) may be density dependent, meaning that individuals change their denning behaviour in response to changes in population density. Increases in den use due to changes in density may result in increases in bovine tuberculosis (Mycobacterium bovis; bTB) transmission among possums, as infection has previously been correlated with den use. In this study, ...

BACKGROUND A reduction in the number of podocytes and podocyte density has been documented in the kidneys of patients with diabetes mellitus. Additional studies have shown that podocyte injury and loss occurs in both diabetic animals and humans. However, most studies in animals have examined relatively long-term changes in podocyte number and density and have not examined effects early after in...

Background: Many studies have shown that a reduction in low-density lipoprotein cholesterol (LDL-C) is associated with lower risk of cardiovascular disease. It has been suggested that the reduction of cardiovascular risk is proportional to the reduction in LDL-C. However, cholesteryl ester transfer protein (CETP) inhibitors have not been shown to follow this pattern. These medications increase ...

The diffusional isotope effect of a monatomic Lennard-Jones liquid is calculated by molecular-dynamics simulation. Mass differences of 10-40 % were used. At equilibrium density, with decreasing temperature a strong reduction of the isotope effect is found that indicates a marked increase of the collectivity of motion. Changing the density at constant temperature, the same effect is seen that sh...
