Groups of embryonate eggs were given 250, 500, 750, and 1000 r of x-radiation. 18 hours later, these 4 groups, together with a control group, were injected intra-allantoically with influenza A virus. Radiation at all dosage levels caused significant changes in the infectivity titre curves during the next 90 hours. The most striking alterations were the prolonged incubation period and the unifor...

The effect of oral administration of aqueous extract of Corchorus olitorius (AECO) at doses of 250 mg/kg BW, 500 mg/kg BW and 750 mg/kg BW on haematological and plasma biochemical parameters in male albino rats were investigated. The extract was administered on daily basis for 30 days and blood samples were collected for haematological and plasma biochemical assays. Treatment of rats for 30 day...

Aerial parts of Echinops echinatus (Family: Asteraceae) were subjected to in vivo hepatoprotective study in order to validate its traditional use in hepatobiliary disorders, by native people of Cholistan Desert, Pakistan. Hepatoprotective effects of pre-treatment with aerial parts (ethanolic extract) of E. echinatus (EE), (500 and 750 mg/kg/day, p.o., for 7 days) against CCl4 (0.75 ml/kg., s/c....

PURPOSE To determine how the ADC value of parotid glands is influenced by the choice of b-values. MATERIALS AND METHODS In eight healthy volunteers, diffusion-weighted echo-planar imaging (DW-EPI) was performed on a 1.5 T system, with b-values (in seconds/mm2) of 0, 50, 100, 150, 200, 250, 300, 500, 750, and 1000. ADC values were calculated by two alternative methods (exponential vs. logarith...

BACKGROUND Vestibular evoked myogenic potential (VEMP) testing has gained increased interest in the diagnosis of a variety of vestibular etiologies. P13/N23 latency, amplitude and threshold response curves have been used to compare pathologic groups to normal controls. Appropriate characterization of these etiologies requires normative data across the frequency spectrum and age range. PURPOSE...

Di-(2-ethylhexyl)-phthalate (DEHP), the most widely utilized industrial plastizer and a ubiquitous environmental contaminant, can act on peroxisome proliferators-activated nuclear hormone receptor family (PPAR) isoforms. To understand the contribution of sphingolipid metabolism to DEHP-induced hepatotoxicity, effect of DEHP exposure on activities of sphingolipid metabolic enzymes in rat liver w...

Usage of aesthetically appealing native plants in urban landscape projects can support its conservation by contributing to genetic diversity and their sustainability in that region. Lycium shawii is a thorny perennial shrub with an ability to tolerate extreme climatic conditions prevalent in Kuwait. In this germination study, effects of dry heat (50°C) and/or various concentrations (500, 750 an...

We studied differences in imaginary coherence (IC) of the gamma band between brain regions of female schizophrenia patients during the auditory oddball task using magnetoencephalography (MEG). Subjects were 12 right-handed female schizophrenia patients, who were evaluated by the Positive and Negative Syndrome Scales (PANSS). Functional connectivity during an auditory oddball task was reconstruc...

The aim of this study was to assess the teratogenicity of the herbicide glyphosate-Roundup (as commercialized in Brazil) to Wistar rats. Dams were treated orally with water or 500, 750 or 1000 mg/kg glyphosate from day 6 to 15 of pregnancy. Cesarean sections were performed on day 21 of pregnancy, and number of corpora lutea, implantation sites, living and dead fetuses, and resorptions were reco...
