background: this study aimed to assess the effectiveness of topiramate, a glutamate-modulating agent, in patients with treatment-resistant obsessive-compulsive disorder (ocd) as an adjunct to serotonin reuptake inhibitors (sris). materials and methods: thirty-eight patients with refractory ocd, were randomly assigned to receive topiramate or placebo. this study was designed as a 12-week, double...
The effect of Al2O3 (1-10 wt %) and Y2O3 (1-10 wt %) additions on thermochemical heat storage properties of Co3O4/CoO system was investigated by thermogravimetry, XRD, and SEM analyses. Results showed that the addition of Al2O3 to Co3O4 at constant 8 h mechanical activation improved the...
BACKGROUND The Internet is known to be used for health purposes by the general public all over the world. However, little is known about the use of, attitudes toward, and activities regarding eHealth among the Japanese population. OBJECTIVES This study aimed to measure the prevalence of Internet use for health-related information compared with other sources, and to examine the effects on user...
We have devised one 160 bits improved hash algorithm based on MD5 and SHA1. And in additional, we also introduce four assistant functions named:F(X,Y,Z), G(X,Y,Z), H(X,Y,Z), and I(X,Y,Z) to do 4 rounds of 16 steps iterative operation with 32-bit data as input and 32-bit as output, saving in A, B, C, D respectively. Then we use one new extending function K(X,Y,Z) to expand 32-bit A, B, C, D to 4...
Many MRI techniques require prior knowledge of the T1-relaxation time of blood (T1bl). An assumed/fixed value is often used; however, T1bl is sensitive to magnetic field (B0), haematocrit (Hct), and oxygen saturation (Y). We aimed to combine data from previous in vitro measurements into a mathematical model, to estimate T1bl as a function of B0, Hct, and Y. The model was shown to predict T1bl f...
BACKGROUND Biomass smoke is associated with the risk of chronic obstructive pulmonary disease (COPD), but few studies have elaborated approaches to reduce the risk of COPD from biomass burning. The purpose of this study was to determine whether improved cooking fuels and ventilation have effects on pulmonary function and the incidence of COPD. METHODS AND FINDINGS A 9-y prospective cohort stu...
The current experiment was designed to evaluate the effect of plant growth promoting rhizobactria (PGPR) on chlorophyll fluorescence and some physiological parameters in basil (Ocimum basilicum L.) leaf under salinity stress. The experiment was conducted in factorial arrangement based on completely randomized design. Treatments were four levels of salt stress (0, 40, 80 and 120 mM of NaCl) and ...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
