it is the output power and density of the lasers which determine whether a laser is a low or high-power one. if the density is less than 670mw/cm2, the laser is called a low power one. the output power of these lasers is usually less than 250mw. they use different mechanisms to accelerate wound healing such as: cellular biostimulation, improvement of circulation, vasodilation, analgesic and ant...

in order to identify the pressure patterns causing the cold weather over the northwestern iran, daily lowest temperatures of six stations of the study area during january- march months of the 1986-2003 period were obtained from meteorological organization of islamic republic of iran (irimo) in the quality controlled format. according to the defined threshold, the very cold days were extracted a...

The present study seeks to provide acoustic evidence of articulatory adjustments to initiate and sustain voicing during stops. First, using aerodynamic and acoustic data, it examines variations in the amplitude of voicing in phraseinitial voiced stops in Spanish and English and relates these variations to articulatory adjustments to preserve a low oral pressure and voicing. Second, a correlatio...

conclusions in conclusion, oral l-arginine supplementation appears to improve anthropometric parameters, blood pressure values, and some blood biochemical indices associated with cardiovascular disease prevention. results significant decreases in anthropometric parameters, blood pressure (sbp, dbp), fbs, hba1c, ldl, mda (p < 0.001), tg (p = 0.02), and tc (p = 0.002) and a significant increase i...

background: feeding intolerance is prevalent in very low birth weight (vlbw) neonates and is a barrier for better and faster growth in these neonates. some studies have supported the administration of oral probiotic to decrease feeding intolerance. the aim of this study was to evaluate the effect of probiotic on feeding intolerance in vlbw neonates. methods: this randomized clinical trial study...

conclusions garlic powder consumption can reduce blood pressure, yet in this model, it did not have an effect on the interaction between renin angiotensin system and nitric oxide inhibition. results at the beginning and at the end of experiments, systolic blood pressure was higher in the hypertensive groups than the normotensive group. however, at the end of the study, diastolic blood pressure ...

background and aim: low back pain is a common complaint in communities which has negative effects on different aspects of life. an effective method for reduction of low back pain complications is foot reflexology. foot reflexology has a positive effect in reduction of complications in low back pain. foot reflexology reduces respiratory rate, blood pressure and pulse rate. this study is an inves...
