objective: experiencing pleasant events during daily life has a significant positive role in the personal mental health and acts as a keystone for “behavioral activation” (ba) interventions. there are serious differences in the pleasant event schedules in different cultures and countries. we aimed to develop a persian checklist of pleasant events (pcpe) to provide and validate a cu...
abstract background: nowadays, prevalence of addictive behaviors among bipolar patients is considered to be a serious health threat by the world health organization. the aim of this study is to investigate the role of behavioral activation and inhibition systems in predicting addictive behaviors of male patients with bipolar disorder at the roozbeh psychiatric hospital. materials and methods: t...
the purpose of this study was to investigate the brain activation patterns in response to thehuman color preference by using a functional magnetic resonance imaging (fmri). a total of 31 healthyhumans without color blindness were participated in this study. the brain activation was induced by viewingof eight different colors: black, gray, blue, green, earthy yellow, red, yellow and white. the q...
objective(s): hardystonite (ht) is zn-modified silicate bioceramics with promising results for bone tissue regeneration. however, ht possesses no obvious apatite formation. thus, in this study we incorporated sr and ti into ht to prepare sr-ti-hardystonite (sr-ti-ht) nanocomposite and evaluated its in vitro bioactivity with the purpose of developing a more bioactive bone substitute material. ma...
aim and background: the behavioral inhibition system (bis) and the behavioral activation system (bas) are considered as factors to verify the effects of personality significance on cortical activity. the present study explored the effects of the bis and bas on frontal asymmetry in response to affect stimuli. methods and materials: this study included 36 individuals (18 with high bas sensitivity...
composite solid propellants were prepared with and without nano-alloys (ti-co, ti-ni, ti-zn), where nano-alloys used as catalyst. these nano-alloys are prepared by hydrazine reduction method. catalytic properties of these nanomaterials were measured on ammonium perchorate/hydroxyterminatedpolybutadiene propellant by thermogravimetery analysis and differential thermal analysis. both experimental...
oocyte activation (aoa), results in high fertilization rates. objective: this prospective, randomized, unblinded clinical study aimed to evaluate the efficiency of calcium ionophore on fertilization and pregnancy rate after intracytoplasmic sperm injection (icsi) in infertile men suffer from teratoospermia. materials and methods: thirty eight women with teratoospermic partner underwent icsi wit...
this study reports the removal of cadmium from wastewater in batch mode, using two carbonaceous adsorbents viz. sunflower head carbon (shc) and sunflower stem carbon (ssc) prepared from waste biomass of sunflower. the adsorbents were characterized by fourier transform infrared spectroscopy (ft-ir), scanning electron microscopy (sem) and energy dispersive x-ray analysis (edx). the results of bat...
thin layer drying of russian olive (elaeagnusan gastifolial l.) fruit using a hot air dryer in order to calculate effective moisture diffusivity, activation energy and energy consumption has been evaluated in this article. the selected variables included three levels of air velocity of 0.5, 1 and 1.5 m/s and three air temperature levels of 50, 60 and 70°c. increased air temperature increased ef...
derivatives of phenyl-keto butenoic acids have been reported to be inhibitors of pyruvate decarboxylase, (pdc). the inhibition of transketolase, a thiamine requiring enzyme such as pdf, by meta nitrophenyl derivative of 2-oxo-3-butenoic acid (mnpb) is reported here. these studies indicate that the inhibitor binds to the enzyme at the active site. a two-step inhibition was observed, first the in...
