The purpose of this article was to compare the mean value of optical density of four porcelains commonly used for fabrication of inlay/onlay prostheses using direct digital radiograph. The sample consisted of 20 2-mm thick porcelain specimens (measured by digital pachymeter): Empress (Ivoclair), Simbios (Degussa), Vita Omega 900 and Vitadur Alpha (Vita Zahnfabrik). The values of optical density...

We prove that for continuous stochastic processes S based on ((; F; P) for which there is an equivalent martingale measure Q 0 with square-integrable density dQ 0 =dPwe have that the so-called "variance optimal" martingale measure Q opt for which the density dQ opt =dPhas minimal L 2 (P)-norm is automatically equivalent to P. The result is then applied to an approximation problem arising in Mat...

BACKGROUND The current study investigates circulating eosinophils and neutrophils in Alzheimer's (AD) type dementia with respect to density (kg/L). The existence of β-amyloid plaques in the brain is a feature of AD. Sporadic scientific reports indicate that the disease affects circulating neutrophils. In contrast, numerous publications investigate inflammatory reactions in AD brains. Locally, t...

Mononuclear phagocytes (MPs) from human peripheral blood were separated on discontinuous Percoll gradients into two subpopulations. A high density population was isolated which contained less mature MPs, while the MPs in the low density population were more mature cells. The proportion of high density MPs was found to increase sharply in conjunction with the peripheral blood monocytosis associa...

OBJECTIVE The investigation of the association between retinol-binding protein 4 (RBP4) and lipoproteins in subjects with hypertriglyceridemia. DESIGN Forty-six obese or overweight hypertriglyceridemic patients were studied at baseline and 20 of them underwent a hypocaloric low-fat diet for 3 months. RESULTS Plasma RBP4 levels were positively correlated with serum triglycerides (TG) in the ...

Puberty is characterized by major changes in hormone levels and structural changes in the brain. To what extent these changes are associated and to what extent genes or environmental influences drive such an association is not clear. We acquired circulating levels of luteinizing hormone, follicle stimulating hormone (FSH), estradiol and testosterone and magnetic resonance images of the brain fr...

OBJECTIVE This study investigated the relationship between circulating soluble receptor for advanced glycation end products (sRAGE) and parameters of bone health in patients with Charcot neuroarthropathy (CNA). RESEARCH DESIGN AND METHODS Eighty men (aged 55.3±9.0 years), including 30 healthy control subjects, 30 type 2 diabetic patients without Charcot, and 20 type 2 diabetic patients with s...

A high level of atmospheric particulate matter induces an increase in circulating polymorphonuclear leukocyte (PMN) counts and an increase in serum inflammatory cytokine levels. The particulate level in Antarctica is extremely low compared with that in industrial countries. We hypothesized that this low level would reduce circulating leukocyte counts and serum inflammatory cytokine levels in pe...

harvesting of timber using ground based machinery is still a common practice around the world. track and road building, and movement of machinery during harvesting operations cause soil disturbance. therefore the aim of this study was to investigate the change in soil properties after logging operation on skid trails (2 years and 7 years after logging) and compare disturbed soil properties with...
