The association of the severity of obstructive sleep apnea with plasma leptin levels
(Amer Medical Assoc., 2003)
Objective: To examine whether circulating leptin levels correlate with the severity of disease in patients with obstructive sleep apnea. Design: Prospective nonrandomized study. Setting: Referral sleep laboratory for ...
Combined radiofrequency modified maze and mitral valve procedure through a port access approach: early and mid-term results
(Oxford University Press, 2003)
Objective: The aim of this study was to assess the feasibility and effectiveness of irrigated radiofrequency (RF) modified Maze procedure through a port access approach during mitral valve surgery and evaluate early and ...
Selective liquid-liquid extraction of mercuric ions by octyl methane sulfonamide
(Marcel Dekker Inc, 2003)
N-octyl methane sulfonamide (OMSA) has been demonstrated to be a very efficient reagent for selective extraction of Hg(II) ions from aqueous solutions. The extraction bases on rapid reaction of OMSA with Hg(II) ions yielding ...
Comparison of intraoperative transit-time flow measurement with early postoperative magnetic resonance flow mapping - in off-pump coronary artery surgery
(Texas Heart Inst., 2003)
The purpose of this prospective study was to evaluate graft patency of off-pump coronary artery surgery intraoperatively by transit-time flow measurement and to compare this technique with postoperative magnetic resonance ...
Influence of cardiovascular risk factors on the outcome of coronary artery bypass surgery
(Springer Verlag, 2003)
Purpose. To assess the impact of gender age and other cardiovascular risk factors on the outcomes of patients undergoing coronary artery bypass grafting (CABG). Methods. A total of 5 067 consecutive patients undergoing ...
A glycidyl methacrylate-based resin with pendant urea groups as a high capacity mercury specific sorbent
(Elsevier Science Bv, 2003)
Polymer-supported pendant urea groups have been demonstrated to be very efficient in selective removal of mercuric ions from aqueous solutions. Methyl methacrylate (0.5 mol)-glycidyl methacrylate (0.4 mol)-divinylbenzene ...

(Masson Editeur, 2003)
Objective: To evaluate the use of corneal ring segments (INTACS) for the treatment of asymmetrical astigmatism in keratoconus. Material and methods: This prospective study involved nine eyes of seven patients who were ...
Zero-crossing based demodulation of minimum shift keying
(2003)
Minimum shift keying (MSK) modulation has features such as constant envelope compact spectrum and good error performance which are all desirable in many digital applications including mobile radio. Numerous receiver ...
Left versus bi-atrial intraoperative saline-irrigated radiofrequency modified maze procedure for atrial fibrillation
(2003)
Background: This study was conducted to evaluate the effectiveness of the saline-irrigated radiofrequency modified maze operation for the treatment of chronic atrial fibrillation (AF) and compare the results of the left ...
