PURPOSE This study aimed to investigate efficient approaches for determining internal target volume (ITV) from four-dimensional computed tomography (4D CT) images used in stereotactic body radiotherapy (SBRT) for patients with early-stage non-small cell lung cancer (NSCLC). MATERIALS AND METHODS 4D CT images were analyzed for 15 patients who received SBRT for stage I NSCLC. Three different IT...

Observed associations between depression following myocardial infarction (MI) and adverse cardiac outcomes could be overestimated due to patients' tendency to over report somatic depressive symptoms. This study was aimed to investigate this issue with modern psychometrics, using item response theory (IRT) and person-fit statistics to investigate if the Beck Depression Inventory (BDI) measures d...

Recently, the rs1042713 G > A and rs1042714 C > G polymorphisms in the beta-2 adrenergic receptor (ADRB2) gene were shown to be related to atherosclerosis diseases. Therefore, we performed a systemic meta-analysis to determine whether the two functional polymorphisms are related to the risk of myocardial infarction (MI) and coronary artery disease (CAD). We identified published studies that are...

It is proved that an irreducible quasifinite W∞-module is a highest or lowest weight module or a module of the intermediate series; a uniformly bounded indecomposable weight W∞module is a module of the intermediate series. For a nondegenerate additive subgroup Γ of F, where F is a field of characteristic zero, there is a simple Lie or associative algebra W(Γ, n)(1) spanned by differential opera...

AIMS To determine the prognostic value of baseline plasma adiponectin levels in patients with known or suspected coronary artery disease referred for coronary angiography. METHODS AND RESULTS Adiponectin was measured in 325 male patients with stable angina, troponin-negative unstable angina, and non-ST-segment elevation myocardial infarction (MI) undergoing coronary angiography at a Veterans ...

We will say that a 3-manifold is almost compact if it can be obtained from a compact manifold N by removing a closed subset of dN. Then Theorem 1 is equivalent to the assertion that the universal covering of M is almost compact. A natural way to attempt to generalize Theorem 1 is to show that other coverings of M are almost compact. It was conjectured by Simon [Si] that if M is any compact P-ir...

BACKGROUND Diabetic patients who present with unstable angina or non-ST-elevation myocardial infarction suffer a substantially greater incidence of subsequent infarction or death compared with nondiabetic patients. The present study was undertaken to examine whether diabetic patients in the Platelet Receptor Inhibition in Ischemic Syndrome Management in Patients Limited by Unstable Signs and Sy...

Recent findings suggest that inflammation plays a role in atherosclerosis and its acute complications. Cellular response in infections with Gram-negative bacteria is mediated by bacterial lipopolysaccharide (LPS), which activates monocytes to expression of cytokines, growth factors, and procoagulatory factors via LPS receptor CD14. Endothelial cells and smooth muscle cells are stimulated by a c...

OBJECTIVE The purpose of this study was to analyze the interrelationship among oxidation, myocardial infarction (MI), and type 2 diabetes in a population-based case-control study of MI. RESEARCH DESIGN AND METHODS Participants were 1,709 individuals from western New York: 257 women and men with incident MI and 1,452 healthy control subjects (aged 35-70 years). Lipid peroxidation was measured ...

BACKGROUND The present study was conducted to evaluate the effect of different topical agents utilized for prevention of enamel decalcification around orthodontic brackets bonded to bleached and non-bleached enamel. METHODS Human maxillary premolars (n = 120) were divided into two equal groups. Teeth in group I were left without bleaching while those in group II were bleached with Vivastyle g...
