The aim of this work is to analyse Maximum Admissible Concentration (MAC) values proposed for irritants by the Group of Experts for Chemical Agents in Poland, based on the RD50 value. In 1994-2004, MAC values for irritants based on the RD50 value were set for 17 chemicals. For the purpose of the analysis, 1/10 RD50, 1/100 RD50 and the MAC/RD50 ratio were calculated. The determined MAC values ar...
There is no scientific consensus that a relationship exists between the ABO blood group and personality traits. However, a recent study hypothesized that the dopamine beta-hydroxylase (DBH) gene is in linkage with the ABO gene. The sample population consisted of 1,427 healthy Japanese subjects who completed the Temperament and Character Inventory (TCI). Each subject's ABO blood type was determi...
Background : The irritable bowel syndrome is one of the common gastrointestinal disorder and according to biopsychosocial model, personality traits play major role in onset, relapse and severity of IBS. The aim of the current research was to determine the personality traits of IBS patients. Materials and Methods: In this analytical cross -sectional study, the personality traits of...
background: the thiol-specific antioxidant (tsa) is an antigen of leishmania major which is believed to be the most promising molecule as a vaccine candidate against leishmaniasis. objectives: in this study, we investigated the protective efficacy of tsa-based dna vaccine against l. major infection. materials and methods: recombinant plasmid construction tsa (pctsa) was prepared and transfected...
Stress tests are commonly applied in shrimp hatcheries to estimate the quality of postlarvae to be used during growout. The highest larval survival rate during culture and in shrimp stress tests has been reported when specimens are offered a diet containing high levels of highly unsaturated fatty acids ( HUFA ) . Also vitamin C has positive effect to resistance and survival of larvae . In this ...
in the management of river basins, prediction of river water quality is essential to maintain water quality within standard limits. this study performed a time-series analysis of the prediction of chlorine concentration and electrical conductivity time series data for the period of 1991-2005 from sefidrood river in northern iran. the seasonal prediction of chlorine and electrical conductivity t...
introduction: presence of a sore throat after surgery is a common side effect of general anesthesia with intratracheal intubation and can cause discomfort for the patient and prolong the recovery process. in this study we compared the effect of dexamethasone before and after intubation on the incidence of sore throat after tympanoplasty surgery. materials and methods: in a double-blind, rando...
According to the social motivation hypothesis of autism, individuals with high levels of autistic traits experience reduced levels of reward from social interactions. However, empirical evidence to date has been mixed, with some studies reporting lower levels of social reward in individuals with Autism Spectrum Disorder (ASD), and others finding no difference when compared to typically developi...
In order to study the effects of salinity on germination, vegetative growth and some physiological characteristics of canola cultivars, two experiments were conducted at Research Station of Agricultural College of University of Kerman in 2004. The experimental design was a Completely Randomized Block with four replications. Treatments comprised all combinations of different levels of three fact...
introduction: the purpose of this in vitro study was to compare the accuracy of working length determination using the apex locator versus conventional radiography in c-shaped canals. methods and materials: after confirming the actual c-shaped anatomy using cone-beam computed tomography (cbct), 22 extracted c-shaped mandibular second molars were selected and decoronated at the cemento-enamel ju...
