<span>Determining and classifying pathological human sounds are still an interesting area of research in the field speech processing. This paper explores different methods voice features extraction, namely: Mel frequency cepstral coefficients (MFCCs), zero-crossing rate (ZCR) discrete wavelet transform (DWT). A comparison is made between these order to identify their ability any input sou...

gastroesophageal reflux disease (gerd)  is defined with clinical symptoms  of  heart burning and regurgitation. it may be associated with external esophageal symptoms such as chronic cough, asthma, laryngitis, chronic lung disease, sinusitis and pulmonary fibrosis. in the present study, rats with chronic aspiration of gastroduodenal contentswere studied for  cellular phenotypes  and  cytokine c...

BACKGROUND Gastro-oesophageal reflux disease (GORD) is a chronic condition affecting up to one-quarter of the Western population. GORD is characterized by heartburn and acid regurgitation, but is reported to be associated with a spectrum of extra-oesophageal symptoms. OBJECTIVE The aim of this systematic review was to critically evaluate postulated extra-oesophageal symptoms of GORD. METHOD...

INTRODUCTION Saliva plays a key role in the homeostasis of the digestive tract, through its inorganic components and its protein growth factors. Sjögren's syndrome patients have a higher prevalence of gastroesophageal reflux disease and laryngopharyngeal reflux. Decreased salivary transforming growth factor alpha levels were observed in dyspeptic patients, but there have been no studies in pati...

We performed a thermographic study to observe any possible interaction between the esophageal acid perfusion and the temperature changes of skin surface in patients with gastroesophageal reflux disease (GERD). Twenty-seven patients with GERD were categorized as group I(globus symptoms with posterior laryngitis) and group II (heartburn and/or regurgitation symptoms). Patients and 6 healthy volun...

Radio telemetry equipment has significantly improved over the last 10-15 years and is increasingly being used in research for monitoring a variety of physiological parameters in non-sedated animals. The aim of this review is to provide an update on the current state of development of radio telemetry for recording respiration. Our literature review found only rare reports of respiratory studies ...

GER is a common condition affecting many patients in different parts of the world. It usually presents with the classic manifestations of heartburn and regurgitation; however, in some it can also present with extraesophageal manifestations such as chronic cough, laryngitis, asthma or chest pain. Commonly employed diagnostic tests such as EGD and ambulatory pH or impedance monitoring in GER, are...
