These weighted cuffs have been used successfully by three multiple sclerosis patients to decrease upper extremity tremors and thus facilitate independent fine coordination activity. We have also used the cuffs with a brain-injured patient to decrease tremors and increase proprioception. With all these patients, working fasteners during dressing and eating were easier tasks when the cuffs were w...

Although trachea! tube cuffs are well known to injure the trachea, attempts to design safer cuff systems have been only partially successful. In 14 dogs, we compared three models of high residual volume, low pressure cuffs, which are considered to be among the safest. Two were air-filled cuffs —a maintained pressure cuff and a balloon reser voir cuff —and the third was foam-filled. Trachea!...

according to technical presages, in the preliminary studies, we have found that there are at least 12 different kinds of stucco decorations belonging to the islamic periods of iran. technical executive details in each kind of these decorations depending on composition and method of treatment, manner of forming, and measure of relieve are different. unlike two common categorizations which are ba...

the study, the second-year females’ choice of mate showed no effect of bower treatment, but they did in year 2, when even more decorations were added. An age-biased effect is not restricted to female responses to bower decorations, but also applies to male display intensity. The more intense the male display during the second stage of courtship, the more likely were older females to visit a mal...

BACKGROUND When conventional high-volume, low-pressure cuffs of endotracheal tubes (ETTs) are inflated, channel formation due to folds in the cuff wall can occur. These channels facilitate microaspiration of subglottic secretions, which is the main pathogenic mechanism leading to intubation-related pneumonia. Ultrathin polyurethane (PU)-cuffed ETTs are developed to minimize channel formation in...

BACKGROUND Current tracheal tubes (TTs) cannot guarantee a perfect seal against pulmonary aspiration of upper airway secretions. The purpose of this study was to investigate whether a gel layer between the tracheal tube with double cuffs (Double cuffs) prevents fluid leakage past TT cuffs. METHODS In vitro fluid leakage tests were performed using the Double cuff with or without a gel layer be...
