medical environments such as hospital waiting rooms can affect a client’s anxiety level as wellas psychological and physiological responses to his or her situation. the aim of this research was to evaluatethe use of environmental design, specifically the design which incorporates elements of nature, in clinics andhospitals to decrease anxiety, blood pressure and pulse rates of waiting clients. ...

The changes in total polyphenolics in elderberry (Sambucus nigra) following treatment with various doses of pulsed ultraviolet rays (UV) were investigated. Four pulsed UV durations (5, 10, 20, 30 seconds) at three energy dosages (4500, 6000, 11,000 J/m/pulse) were considered for the research. All treated elderberry fruits were incubated for 24 h at room temperature (25 ̊C) following treatment to...

Little is known about the efficacy of pulsed ultrasound compared with continuous ultrasound. Previous studies on the efficacy of pulsed ultrasound were not systematic and gave different results. In this study, the effects of pulse length, pulse interval, pulse length × pulse intervals, and treatment time on sonochemical activity were investigated using a simple oxidation of iodide method and a ...

background thrombolytic therapy in patients with sub-massive pulmonary embolism (smpte) needs further assessment. objectives the current study aimed to assess a potential benefit of thrombolytic and non-thrombolytic therapy in patients with smpte. patients and methods one hundred-nineteen patients were enrolled with smpte from 2006 to 2010 in the tertiary care center of rajaie medical and resea...

BACKGROUND Port wine stains (PWS) are formed by dilation and malformation of dermal capillaries without endothelium proliferation. Despite the improvements in lasers and light therapy for PWS therapy in the past 10 years, the 'cure' rate is only about 10%. Intense pulsed light (IPL) is a non-coherent light based on the theory of selective photothermolysis. OBJECTIVE To evaluate the efficacy o...

OBJECTIVE The effects of acute hemodialysis session on pulse wave velocity are conflicting. The aim of the current study was to assess the acute effects of ultrafiltration on the aortic mechanical properties using carotid-femoral (aortic) pulse wave velocity and pulse propagation time. METHODS A total of 26 (12 women, 14 men) consecutive patients on maintenance hemodialysis (mean dialysis dur...

in this work, the influence of different edm parameters (pulse current, pulse voltage, pulse on-time , pulse off-time) in finishing stage on  the surface roughness (r a )  as a result of application copper electrode to a workpiece( cold work steel  din1.2379)  has been investigated. design of the experiment was chosen as full factorial. statistical analysis has been done and artificial neural n...

The cellular effects of gastric electrical stimulation (GES), which has recently been introduced as a potential therapy for the treatment of gastroparesis and obesity, were investigated in rat antrum smooth muscle cells (SMCs). Effects on cell membrane potentials of single electrical current pulses (pulse width from 0.1 ms to 200 ms) and 2-s pulse train stimuli with different pulse widths (0.1-...

Modified-Electroconvulsive Therapy (m-ECT) is administered for the treatment of various psychiatric disorders. The Seizure Generalization Hypothesis holds that propagation of the induced seizure throughout the whole brain is essential for the effective ECT intervention. However, we encounter many clinical cases where, due to high thresholds, seizure is not induced by the maximum dose of electri...
