Two experiments measured the cardiovascular responses of fourth- and fifth- grade boys to tasks that were relevant to Type A characteristics. Boys were classified as Type A or Type B by the Adolescent Structured Interview (ASI) and Matthews Youth Test for Health (MYTH). Results showed that ASI and MYTH assessments were significantly and moderately correlated--a finding similar to the associatio...

BACKGROUND AND PURPOSE Intracerebral hemorrhage (ICH) accounts for approximately 10% of stroke cases. Hypertension may play a role in the pathogenesis of ICH that occurs in the basal ganglia, thalamus, pons, and cerebellum, but not in that of lobar ICH. Hypertension contributes to decreased elasticity of arteries, thereby increasing the likelihood of rupture in response to acute elevation in in...

A commercially available amorphous Silicon Electronic Portal imaging device (aSi-EPID) installed onto Siemens Oncor Linear accelerator was evaluated with the objective to be implemented for IMRT quality assurance. EPID properties were investigated; these include reproducibility, dependences between the relative EPID responses and field size, dose rate were studied for both photon beams. To dete...

Ssy1p and Ptr3p are components of the yeast plasma membrane SPS amino acid sensor. In response to extracellular amino acids this sensor initiates metabolic signals that ultimately regulate the functional expression of several amino acid-metabolizing enzymes and amino acid permeases (AAPs). As a result of diminished leucine uptake capabilities, ssy1Delta leu2 and ptr3Delta leu2 mutant strains ar...

Radon is naturally released from the soil into the surface layer of the atmosphere, and by monitoring the natural radioactivity data of radon and its shot-live decay products we can get valuable information about the dilution properties of the lower boundary layer. This paper explores the dispersion characteristics of the lower layer of the atmosphere in Lanzhou, China, and the close relationsh...

BACKGROUND Finding an effective treatment for acne that is well tolerated by the patients is a challenge. One study has suggested the efficacy of tea tree oil in treatment of the acne vulgaris. AIM To determine the efficacy of tea tree oil in mild to moderate acne vulgaris. METHODS This was a randomized double-blind clinical trial performed in 60 patients with mild to moderate acne vulgaris...

PURPOSE To analyze aortic elastic properties (AEP) characteristics, dissection and elastic data of ascending aorta (AA) in the population with a high risk of aortic diseases. METHODS Forty five patients with artery diseases undergoing aortic digital subtraction angiography (DSA) were enrolled in this study. The maximal, minimal diameter and changes in diameter of ascending and descending aort...

BACKGROUND Multidetector row computed tomography (MDCT) is an attractive noninvasive imaging modality to detect coronary atherosclerotic plaques which may be underestimated by conventional angiography. However, its routine clinical use is limited due to contrast-associated problems, high cost, inapplicability at bedside and exposure to radiation. Thus, exploring safer and more practical measure...
