“In this study we focused on thermal sensation at fingertip under the influence of applied external pressure via a tourniquet at the upper arm. The perceived thermal sensation
has found to be closely related to the skin temperature (Tsk) that is regulated by the skin blood flow (SkBF), whereas SkBF is easily influenced by external pressure. We thus hypothesized that the perceived thermal sensation, the Tsk and SkBF form such a cross-coupled triad that jointly affects our feeling of thermal comfort. Such interconnections among them were examined in this study using two protocols to investigate the perceived thermal sensation from a given heat stimulus under an exerted external pressure: (1) the SkBF and Tsk, at the Selleckchem Cl-amidine right hand index finger under different external pressures at the right upper arm of one male subject, were monitored by a laser-Doppler flowmeter (LDF): (2) subjective thermal feelings (cold, normal and warm) at the right index fingertip of 10 test takers were recorded, while contacting a glass tube filled with water at different temperatures, with/without
50 mm Hg external pressure at the upper arm, while the temperatures of the glass tube and the index fingertip were recorded by an infrared camera. First, it is found that the SkBF and Tsk at the index fingertip reduced significantly with high external pressure applied at the upper arm, while the pressure from our daily clothing is not large enough to generate such an effect. Next,
the applied pressure suppresses the variations in subjective sensory responses towards the thermal stimuli. Our hypothesis on the interconnections among the perceived thermal sensation, the Tsk and SkBF is thus confirmed. Overall, females appear more discerning to temperature change under the given conditions compared to males. (C) 2012 Elsevier Ltd. All rights reserved.”
“Methods: Data was collected using a questionnaire buy VE-821 survey in schools, colleges and universities in the Tayside area of Scotland, UK in February 2010.
Results: A total of 1006 individuals completed the survey [501 (49.8%) males and 505 (50.2%) females], of whom 349 classified their educational institute as a school and 657 as a college/university. Among them 205 (20.3%) reported previous use of mephedrone; 23.4% reported using only using mephedrone on one occasion previously, although 4.4% reported daily use. A total of 56% of those who had used mephedrone, reported at least one unwanted effect associated with its use. A total of 17.6% of users reported ‘addiction or dependence’ symptoms associated with their mephedrone use. A total of 48.8% of users sourced mephedrone from street level dealers, 10.7% from the Internet.
