BACKGROUND Frequent and large cardiovascular and neuroendocrine responses to psychological stress are thought to enhance an individual's risk for cardiovascular diseases. Preliminary data suggest that levels of reproductive hormones affect the magnitude of stress responses, perhaps contributing to the protective effect of ovarian hormones on premenopausal women's rates of coronary heart disease...

OBJECTIVE This study set out to examine whether mothers' individual perceptions of their neighborhood social processes predict their risk for physical child abuse and neglect directly and/or indirectly via pathways involving parents' reported stress and sense of personal control in the parenting role. METHODS In-home and phone interview data were examined cross-sectionally from a national bir...

A COMPARISON OF TORSIONAL STRESS PROPERTIES OF THREE DIFFERENT NICKEL-TITANIUM FILES WITH SIMILAR CROSS-SECTIONAL DESIGN Reid C. Wycoff D.D.S. Marquette University, 2012 The purpose of this study was to compare the in vitro torsional stress characteristics of Twisted Files (SybronEndo, Orange, CA) with two milled files of similar cross section, EndoSequence (Brasseler USA, Savannah, GA) and Pro...

Background and purpose: The safety climate refers to employees’ perception of safety which can be affected by job-related stress in the workplace. This study aimed to assess the safety climate and investigate the relationship between job stress factors and safety climate dimensions in a dairy industry. Materials and Methods: This was a cross-sectional study. The data was collected using two se...

Introduction “Second best no more” was the title of an article written by David C. Joy for Nature Materials [1]. The article was for highlighting a breakthrough made by a team formed between Brookhaven National Laboratory (BNL, USA) and Hitachi High Technologies Corporation (HHT, Japan). Sub-angstrom secondary electron (SE) images were obtained on a Hitachi HD-2700, which is a combined scanning...

In this paper, the bond strength of thermal spray coatings in high speed shafts has been studied. The metallurgical and mechanical studies has been made on the coated samples and shaft using optical microscopy, scanning electron microscopy (SEM). Keywords—Thermal spray, Residual stress, Wear mechanism, HVOF, Gas compressor shafts

The aim of this study was to compare resting coronary flow velocity, determinants of myocardial oxygen demand, and coronary vasodilator capacity in subjects with physiological, exercise-induced, and hypertensive left ventricular hypertrophy. Sixteen healthy sedentary men, 16 endurance athletes, and 16 hypertensive subjects (mean+/-SEM for left ventricular mass index: 94.9+/-5.5, 184.6+/-8.4, 15...

OBJECTIVES To analyse circulating concentrations of advanced glycation end products (AGEs) in patients with severe congestive heart failure (CHF) and after heart transplantation; to identify the potential contribution of kidney function to plasma AGE concentrations; and to determine whether AGE concentrations and parameters of oxidative stress are interrelated. METHODS AND RESULTS Circulating...
