BACKGROUND Organizational changes that involve healthcare hospital departments and care services of health districts, and ongoing technological innovations and developments in society increasingly expose healthcare workers (HCWs) to work-related stress (WRS). Minimizing occupational exposure to stress requires effective risk stress assessment and management programs. METHODS The authors condu...
The purpose of this study was to assess the effect of high altitude (HA) on work of breathing and external work capacity. On the basis of simultaneous records of esophageal pressure and lung volume, the mechanical power of breathing (Wrs) was measured in four normal subjects during exercise at sea level (SL) and after a 1-mo sojourn at 5,050 m. Maximal exercise ventilation (VEmax) and maximal W...
Fish farming in recirculating aquaculture systems (RAS) has been expanding in the recent years, but the effects of water reuse are not well known. The aim of the present study was to compare the growth parameters, stress response and muscle stress- and growth- related gene expression of rainbow trout (Oncorhynchus mykiss) in open system (OS) versus water reuse system (WRS). For this purpose, yo...
OBJECTIVE To describe 5-year hearing preservation rates following microsurgical excision of vestibular schwannoma (VS) via the middle cranial fossa (MCF) approach. STUDY DESIGN Case series with chart review. SETTING This study was performed at a tertiary care academic medical center. SUBJECTS AND METHODS Fifty-seven subjects with VS underwent resection via an MCF approach between February...
In 2005, the Wikipedia became the most popular reference website on the Internet and it has continued to grow in size and popularity ever since. With the increasing reliance on the Wikipedia comes issues of the credibility and provenance of content. In order to address these issues, we have developed a Recommender System for the Wikipedia, which allows the users of the Wikipedia to rate article...
Starch properties and structure of a wheat mutant (WRS-1) high in resistant starch (RS) was compared to that of the wild type (Sumai No.6). In cooked hot flour and retrograded flour, the amounts of RS in mutant WRS-1 were 7.8 and 9.4 times of wild type (0.5 in hot flour and 0.6 in retrograded flour), respectively, and correspondingly the slower and incomplete starch hydrolysis was also in both ...
Asymmetric dimethylarginine (ADMA) is an endogenous competitive inhibitor of nitric oxide (NO) synthase known to exert vasoconstriction of vascular bed. The elevation of ADMA has been considered as the cardiovascular risk factor associated with hyperlipidemia, hypercholesterolemia and metabolic syndrome. ADMA is produced by the action of dimethylarginine dimethylaminohydrolase (DDAH), which hyd...
The acoustic cues of the speech signals which are consisted of consonants and vowels are very important for speech perception in noisy competing situations. Since the perception in noise test is one of the valuable measures in the perception/production abilities, so the objective of this study is to determinate a norm for word recognition in white noise (WN) with a signal-to-noise ratio (SNR) b...
Wolcott-Rallison syndrome (WRS) is a rare autosomal-recessive disorder characterized by the association of permanent neonatal or early-infancy insulin-dependent diabetes, multiple epiphyseal dysplasia and growth retardation, and other variable multisystemic clinical manifestations. Based on genetic studies of two inbred families, we previously identified the gene responsible for this disorder a...
BACKGROUND The regulation of mucociliary clearance is a key part of the defense mechanisms developed by the airway epithelium. If a high aggregate quality of evidence shows the clinical effectiveness of nasal irrigation, there is a lack of studies showing the intrinsic role of the different irrigation solutions allowing such results. This study investigated the impact of solutions with differen...
