the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
The purpose of this study was to clarify which myocardial histological findings associated with dilated cardiomyopathy (DCM) are reflected in quantitative 201Tl myocardial SPECT. We obtained studied SPECT images from 21 patients with DCM 10 minutes and 2 hours after they received an injection of 111 MBq 201Tl at rest. We calculated the percent coefficient of variation of myocardial 201Tl counts...
The mechanism underlying a dose-dependent, reversible increase in serum creatinine (SC) caused by the administration of PA-824, a novel nitroimidazo-oxazine, was evaluated in 47 healthy male and female volunteers. Subjects were administered either 800 or 1,000 mg PA-824 or matching placebo once daily for 8 days. The following renal function parameters were determined before and during dosing an...
BACKGROUND Diabetic cardiac autonomic dysfunction often causes lethal arrhythmia and sudden cardiac death. 123I-Metaiodobenzylguanidine (MIBG) can evaluate cardiac sympathetic dysfunction, and analysis of heart rate variability (HRV) can reflect cardiac parasympathetic activity. We examined whether cardiac parasympathetic dysfunction assessed by HRV may correlate with sympathetic dysfunction as...
In coronary artery disease, the cardiac sympathetic nervous system is closely associated with myocardial ischemia. I-123 metaiodobenzylguanidine (MIBG) imaging allows us to assess the cardiac sympathetic nervous system regionally. One-hundred and eleven patients with single-vessel disease underwent regional quantitative analysis of MIBG imaging before successful percutaneous transluminal corona...
Background: Malignant hyperthermia can be induced by halogenated anesthetics that are inadvertently retained in the anesthetic circuit. Therefore, we compared the desflurane washout times of three different anesthesia workstations. Methods: The AisysTM, Fabius GSTM, and Pro-nextTM workstations were selected and each workstation was tested after connecting a 1-L test lung to the patient side and...
OBJECTIVE To examine the impact of withdrawing rosiglitazone and ramipril medication on diabetes incidence after closeout of the Diabetes REduction Assessment with ramipril and rosiglitazone Medication (DREAM) trial. RESEARCH DESIGN AND METHODS The 3,366 DREAM subjects at trial end who had not developed diabetes while taking double-blind study medication were transferred to single-blind place...
