BACKGROUND Contrary to adaptive support ventilation (ASV), prolonged totally controlled mechanical ventilation (CMV) results in the absence of diaphragm activity and causes ventilator-induced diaphragmatic dysfunction. Because maintaining respiratory muscles at rest is likely a major cause of ventilator-induced diaphragmatic dysfunction, ASV may prevent its occurrence in comparison with CMV. Th...

Biometric offers potential for automatic personal identification and verification, differently from other means for personal verification; biometric means are not based on the possession of anything (as cards) or the knowledge of some information (as passwords). There is considerable interest in biometric authentication based on automatic signature verification (ASV) systems because ASV has dem...

Adaptive servoventilation (ASV) has proven effective at suppressing breathing disturbances during sleep, improving quality of life and cardiac surrogate parameters. Since the publication of the SERVE-HF-trial, ASV became restricted. The purpose of this study was to evaluate the clinical relevance of the SERVE-HF inclusion criteria in real life and estimate the portion of patients with these cri...

BACKGROUND Cheyne Stokes Breathing (CSB), a form of central sleep apnea is often found in medical illnesses such as heart failure, stroke or renal failure. Adaptive servo-ventilation (ASV) has been reported to be an effective treatment of CSB in heart failure. However, there are no reports about using ASV for idiopathic CSB, which is not associated with heart failure or other serious medical pr...

this study was done to determine whether high or low dose of anti-snake venom (asv) is better in coagulopathy in victims of envenoming by vipers. this retrospective study was conducted on the 154 patients (mean age ± sd, range) of viper snake bites who were referred to the emergency ward of razi hospital, ahvaz, iran over 2 years period (2004 - 2006). according to the treatment dosage the patie...

CONTEXT Although antisnake venom (ASV) has been used for many years, selection of an optimal dose is a debated issue due to acute shortage of ASV in India. Despite evidence for smaller doses, most centers still use conventional doses. AIMS This study aimed to evaluate the effects of two different dosage regimens on the outcome of patients with snake envenomation, using a retrospective descrip...

INTRODUCTION Quantitative angiographic assessment after balloon angioplasty is a poor predictor of immediate and long-term outcome. However, the measurement of blood flow velocity during angioplasty has been proved clinically useful. AIMS To analyse the value of the maximal stenotic flow velocity and the presence of stenotic flow velocity acceleration (aSV) for the long-term outcome after bal...

OBJECTIVE Adipocytes secrete a number of molecules such as tumor necrosis factor-alpha, leptin and free fatty acids that can influence the ability of the body to metabolize glucose. Recently, a novel 12.5 kDa cysteine-rich protein, termed resistin, was shown to be secreted by adipocytes. Resistin expression was markedly induced during the conversion of 3T3-L1 cells to mature adipocytes. Express...

Although adaptive servo-ventilation (ASV) therapy is considered clinically beneficial to patients with heart failure (HF), a large proportion of patients fail to show improvement in HF. We aimed to identify reliable markers indicative of a favorable response to ASV. We evaluated 103 consecutive patients with New York Heart Association (NYHA) class II–IV HF who were scheduled for ASV therapy for...

With the growing trend toward remote security verification procedures for telephone banking, biometric security measures and similar applications, automatic speaker verification (ASV) has received a lot of attention in recent years. The complexity of ASV system and its verification time depends on the number of feature vectors, their dimensionality, the complexity of the speaker models and the ...
