spect detects γ-rays from administered radiopharmaceutical within the patient body. γ-rays pass through different tissues before reaching detectors and are attenuated. attenuation can cause artifacts; therefore different methods are used to minimize attenuation effects. in our study efficacy of chang method was evaluated for attenuation purpose, using a custom made heart phantom. due to differe...

background: high intensity interval training (hiit) is a novel training method which has received most attention in recent years. the aim of this study was to examine the effect of 8 weeks of high intensity interval training (hiit) on plasma levels of adiponectin and leptin in overweight nurses. m aterials and methods: 27 nurses (mean age 25.81±60 years, height 158.01±67 cm and weight 69.41±25 ...

background & aim : primary dysmenorrhea (pd) is the most common genital disease among adults which can disrupt daily activities and reduce quality of life. acupressure was recommended for relief of pd and the aim of this study was to compare the maximum pain intensity (mpi) and duration of pd after acupressure on third liver (liv3) and placebo points. methods & materials : students who were suf...

injecting local anesthetic at the seeking current would be appealing.it would save time and avoid potentially dangerous manipulations of the needle. this study aimed to test the hypotheses that in vertical infraclavicular block, injecting local anesthetic at a seeking current of 0.8 ma would produce the same quality of block as injecting at ≤0.5ma. a total of sixty asa i -iii adult patients sch...

Shot peening with steel shot followed by a cleaning process with glass beads is commonly used as surface finish in the production of modular hip endoprostheses. The induced compressive residual stresses increase the resistance against fatigue and fretting fatigue. The surface roughness can be adjusted in a range that enhances the physiological acceptance I compatibility of monolithic ~rnplants....

BACKGROUND A number of programs have been developed to promote the contact between adolescents and mentally-ill patients, in order to break the stigma, improve understanding, promote mental health and prevent substance abuse. The aim of this study was to describe the experience of patients with schizophrenia, high school students, and their social context, participating in a short-term cohousin...

introduction: during the last 3 decades, human is exposed to extremely low frequency electromagnetic fields (elf-emf) emitted by power lines and electronic devices. it is now well accepted that elf-emf are able to produce a variety of biological effects, although the molecular mechanism is unclear and controversial. investigation of different intensities effects of 50 hz elf-emf on cell morphol...

introduction: although many researches showed that there are several psychiatric comorbidities in people suffering from migraine headache, few studies investigated the relationship between deep psychopathological structures and headache variables. the purpose of the present study was to elucidate the relationship between early maladaptive schemas and three dimensions of headache impact, pain in...
