Pruritus (itch sensation) is the most common side effect associated with spinal administration of morphine given to humans for analgesia. A variety of agents have been proposed as antipruritics with poorly understood mechanisms and they are effective with variable success. -Opioid agonists possess several actions that are opposite to -opioid agonists. We proposed to investigate the role of -opi...

an energy based damage index based on a new nonlinear finite element (fe) approach applicable to rc structures subjected to cyclic, earthquake or monotonic loading is proposed. the proposed method is based on the evaluation of nonlinear local degradation of materials and taking into account of the pseudo-plastic hinge produced in the critical sections of the structure. a computer program is dev...

Itching is a common symptom in dermatologic diseases and causes restless scratching of the skin, which aggravates the condition. The mechanism of the itch sensation, however, is enigmatic. The present study included behavioral tests and electrophysiological recordings from rat dorsal root ganglion (DRG) neurons in vivo to analyze the response to pruritic stimuli induced by topical application o...

The single grain scratching SPH simulation model was established to study the subsurface damage of optical quartz glass. Based on analysis stress, strain and force during scratching, generation propagation cracks were studied by combining with scratch elastic stress field model. results show that generate firstly at elastic-plastic deformation boundary in front (? = 28°) due influence maximum p...

Shape deformations of hydrogels are achieved by changing the surface areas isotropic with simple, facile and efficient scratching photolithography patterning methods.

to evaluate antioxidant effects of tomato pomace in broiler diets contained full-fat linseed on the production index, energy and protein efficiency, 396 one-day old ross 308 broilers were randomly allocated to 36 cages for nine dietary treatments with four replicate. this experiment were carried out in a completely randomized design with 3*3 factorial arrangement with three levels of full-fat l...
