In an epidemiological study of occupational dermatitis in 5 different shoe factories, 246 workers were interviewed, examined and patch tested using standard and occupational patch test series. The prevalence of occupational contact dermatitis was 14.6% (36/246): 8.1% (20/246) irritant contact dermatitis (OICD) and 6.5% (16/246) allergic contact dermatitis (OACD). Among the latter, the most comm...
The protozoan intestinal parasite Cryptosporidium commonly infects cattle throughout the world and Iran. The present study was undertaken to determine the abundance and associated risk factors of Cryptosporidium infection in cattle herds of northwestern Iran. A total number of 246 fecal samples from 138 (56.1%) diarrheic (D) and 108 (43.9%) non-diarrheic (ND) cattle were randomly collected and ...
Five cDNA clones encoding 1-aminocyclopropane-1-carboxylic acid (ACC) oxidase (ACO) were isolated from tulip (Tulipa gesneriana L.) by differential screening of the petal cDNA library and were designated as TgACO1, TgACO2, TgACO3, TgACO4 and TgACO5. The deduced amino acid sequences exhibited similarity to ACO proteins from other plant species. Among these proteins, TgACO1-4 have high similarity...
Recent unenclosed iron-fertilization experiments in the equatorial Pacific Ocean have shown that phytoplankton biomass can be increased substantially by the addition of iron. Analyses of size-fractionated chlorophyll indicate that much of the increase during the most recent fertilization experiment, IronEx II, occurred in the .10-mm size fraction. We used flow cytometry, combined with taxon-spe...
OBJECTIVES While computed tomography colonography (CTC) has become a non-invasive alternative to traditional colonoscopy, superficial lesions tend be harder detect, with reports of <2 mm in height being missed. Therefore, for the evaluation lesion detectability using CTC, optimizing scan parameters becomes important. In this study, we investigate effect reconstructed matrix size from CTC on con...
Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide. Mutations of TP53 may reach 70% - 85% in HNSCC patients without human papillomavirus (HPV) infection. Recurrence rate remains particularly high for HNSCC patients with mutations in the TP53 gene although patients are responsive to surgery, irradiation, and chemotherapy early in the treatment. p53-Reactivati...
