OBJECTIVE This investigation assessed preferences for, and effects of, 5 days of twice daily superficial heat, cold, or contrast therapy applied with a commercially available system permitting the circulation of water through a wrap-around garment, use of an electric heating pad, or rest for patients with level II-IV osteoarthritis (OA) of the knee. METHODS We employed a within subject, rando...

The lateral saphenous vein of the dog was perfused with homologous blood at constantflow. Changes in perfusion pressure were used to measure active changes in venous tone. Cooling of the perfusate caused the vein to constrict and warming to relax. Most of the change occurred over the temperature range of 27° to 42°C. The powerful venoconstrictor response to cooling depended on intact sympatheti...

background and purpose: candida species are the most common organisms involved in superficial fungal infections, worldwide. although econazole is among the most frequently used topical formulations for the treatment of candidiasis, no information is available regarding the susceptibility profiles of candida species in iran. materials and methods: in vitro susceptibility of 100 clinical candida ...

Recent studies have suggested the existence of separate transduction mechanisms and sensory pathways for histamine and nonhistaminergic types of itch. We studied whether histamine and an agonist of the protease-activated receptor (PAR)-2, associated with nonhistaminergic itch, excite murine dorsal horn neurons. Single units were recorded in superficial lumbar dorsal horn of adult ICR mice anest...

Recent Monte Carlo computations in realistic port wine stain (PWS) models containing numerous uniformly distributed vessels suggest equal depth of vascular injury at wavelengths of 577 and 585 nm. This finding contradicts clinical experience and previous theory. From a skin model containing normal and PWS vessels in separate dermal layers, we estimate analytically the average volumetric heat pr...

Abstract The results of numerical simulation a turbulent flow in flat channel with periodic inclined ribs by the RANS method are presented. Reynolds number, calculated from rib height and superficial velocity, is Re = 12600. obtained data analyzed order to determine influence inclination angle on heat transfer. It shown that optimal inclination, at which average transfer maximum, 60°.

Miniaturization encourages the development of new manufacturing processes capable of fabricating features, like micro-channels, in order to use them for different applications, such as in fuel cells, heat exchangers, microfluidic devices and micro-electromechanical systems (MEMS). Many studies have been conducted on heat and fluid transfer in micro-channels, and they appeared significantly devi...

Temperature control during experimental ischemia continues to be of major interest. However, if exposure of brain tissue is necessary during the experiment, regional heat loss may occur even when the core temperature is maintained. Furthermore, valid non-invasive brain temperature monitoring is difficult in small rodents. This paper describes a method for both monitoring and maintenance of brai...

CONTEXT Low back pain is one of the most common medical presentations in the general population. It is a common source of pain in athletes, leading to significant time missed and disability. The general categories of treatment for low back pain are medications and therapies. EVIDENCE ACQUISITION Relevant studies were identified through a literature search of MEDLINE and the Cochrane Database ...
