There is an increasing concern about the possible adverse effects of diesel exhaust particulates on human health. In a diesel exposed occupational group composed of 120 toll collectors, a cross-sectional study was performed to evaluate the chest radiographs and 40 toll collectors were selected for computed tomography examination according to hyperinflation and linear markings. The wall thicknes...

BACKGROUND Experimental data demonstrated that inactivation of toll-like receptor (TLR) pathway components attenuated left ventricular (LV) remodeling induced by pressure overload. This study investigated the impact of TLR6 Ser249Pro polymorphism on LV structure in hypertensive subjects. METHODS A sample of 443 patients (266 women and 177 men) was evaluated by clinical history, physical exami...

PURPOSE The aim of this study was to examine the relationship between tooth loss and sub-clinical atherosclerosis in Korean adults. MATERIALS AND METHODS The subjects were part of a cohort study conducted in Ansan city by the Korea University medical school as part of the Korean Genome project. 749 subjects over than 40 years old were evaluated. After taking panoramic radiography, the amount ...

Background Echocardiography (ECHO) is used for diagnosis and management of hypertrophic cardiomyopathy (HCM). Morphologic diagnosis is based on the presence of myocardial thickness of >15mm in adults or a septum to posterior wall ratio of >1.5. Septal wall thickness (WT) >30 mm is one of several high risk features that are used to guide the decision for prophylactic implantable cardioverter-def...

CHEST, 72: 6, DECEMBER, 1977 probably would have demonstrated sonolucency posterior to the posterior left atrial wall. This would suggest a cause other than pericardial effusion for the sonolucency.’ The right atrial angiogram demonstrated an irregular right atrial endocardial border and a 2-cm separation between the right cardiac border and right atrial wall. If the thickness of the separation...

The differentiation of posterobasal myocardial infarction (PMI) from either right ventricular hypertrophy (RVH) or normal subjects displaying an anterior loop (AL) by electrocardiography (ECG) or vectorcardiography (VCG) is difficult. M-mode echocardiography (echo) via the anterior and subxiphoid methods has been helpful in defining cardiac chamber size and wall motion abnormalities. We tested ...

Preoperative CT images of 69 cases (75 sides) of postoperative cysts of the maxilla, seen from 1982 to 1986, were analyzed as to the bony partitions bordering between the cyst and the sinus walls. Three scanned planes, i. e., middle inferior meatus level, superior inferior meatus level, and middle meatus level (each level in 0.5cm distance) were included in the study, and both medial and poster...

The most premature motion change after coronary occlusion is early diastolic thinning of the ischemic left ventricular (LV) wall, with concomitant thickening of the normoperfused wall. We aimed 1). to demonstrate that these early changes are the result of the absence of fluid within the ischemic myocardium (hydraulic skeleton) rather than to cell anoxia and 2). to quantitate the contribution of...
