Influence of Flame Retardants on the Melt Dripping Behaviour of Thermoplastic Polymers.

Melt flow and dripping of the pyrolysing polymer melt can be both a benefit and a detriment during a fire. In several small-scale fire tests addressing the ignition of a defined specimen with a small ignition source, well-adjusted melt flow and dripping are usually beneficial to pass the test. The presence of flame retardants often changes the melt viscosity crucially.

Effects of Exercise Training on Regulation of Skeletal Muscle Glucose Metabolism in Elderly Men.

Background: The aim was to investigate the molecular mechanisms behind exercise training-induced improvements in glucose regulation in aged subjects.

Methods: Twelve elderly male subjects completed 8 weeks of exercise training. Before and after the training period, the subjects completed an oral glucose tolerance test (OGTT) and a muscle biopsy was obtained from the vastus lateralis before and 45 minutes into the OGTT.

Multidisciplinary Aspects of 104 Patients With Pierre Robin Sequence.

Objective: To describe Pierre Robin sequence patients with a cleft palate from a multidisciplinary perspective.

Patients: A total of 104 individuals with Pierre Robin sequence and cleft palate, born between 1980 and 2010.

Method: Data were collected retrospectively and compared with large control groups.

Superiorly based pharyngeal flap for treatment of velopharyngeal insufficiency in patients with 22q11.2 deletion syndrome.

Background: There are no previous blinded studies for comparison of preoperative versus postoperative perceptual speech assessments when using a pharyngeal flap for treating velopharyngeal insufficiency (VPI) in patients diagnosed with 22q11.2 deletion syndrome. The aim of the study was to evaluate the effect of superiorly based pharyngeal flap surgery on speech in these patients using blinded judgments of experienced speech therapists.
