PURPOSE To evaluate the prognostic value of preoperative neck lymph node (LN) assessment with (18)F-fluorodeoxyglucose positron emission tomography ((18)F-FDG PET), computed tomography (CT), and magnetic resonance imaging (MRI) in oral cavity squamous cell carcinoma (OSCC) patients with pathologically positive LN. MATERIALS AND METHODS In total, 47 OSCC patients with pathologically positive L...
study of groundwater quality trend in any region is very important from the view of scheduling and sustainable water resources management. in the present study trend analysis conducted on groundwater quality based on information of 32 piezometeric stations located in the ardabil plain from 1993 to 2008 using the non-parametric spearman test. hydrogeochemical variables studied here are total ani...
abstract: the global warming process during last century has not only affected on meteorological elements but also affected on onset and end of each meteorological elements. for studying probability changes in time series of onset and end date of temperature thresholds 0 and 5 centigrade in country level and deciding the kind and its direction, daily temperature data during the past 45 years (1...
A number of researches have indicated a gradual increase in mean temperature throughout the world. Yet, there are some reports on the reduction of annual mean temperature. In this research we investigated a long-term trend of annual mean temperature in 34 synoptic stations in Iran (2 stations in cold and humid climates 14 in humid and moderate climates, 11 in Steppe climate and 7 in desert clim...
The in vitro interactions of anidulafungin with itraconazole, voriconazole, and amphotericin B were evaluated by using the checkerboard method. For Aspergillus spp., anidulafungin with amphotericin B showed indifference for 16/26 isolates, while anidulafungin with either azole showed a synergy trend for 18/26 isolates. All drug combinations showed indifference for 7/7 Fusarium sp. isolates.
AIM To evaluate the correlation between the levels of CD4, CD8 and CD25 cells and SLE disease in active phase and in remission. METHODS A total of 25 SLE patients, aged between 18-60 years, and fulfilling the ACR criteria with preferential Renal and CNS involvement were included in this study. Baseline CD4/CD8 and CD25 counts, lab parameters etc were conducted. Approximately at the end of 6 m...

The frequency of precipitation extreme event can cause flood or change the drought period. Accurate understanding of these changes is necessary to take action to reduce these effects. In this research, temporal and spatial changes of 14 precipitation indices for eight synoptic stations in the North and West of the country were investigated. For this purpose, after reconstructing the daily preci...
Drought significantly reduces yield of many crop plants including wheat in the world. Identification of wheat genotypes that can thrive on limited water is vital to boost the wheat production of rainfed areas. Forty wheat genotypes were screened for drought tolerance using 0, 7.5, 15 and 22.5% Polyethylene Ethylene Glycol 6000 solutions at PMAS Arid Agriculture University, Rawalpindi, Pakistan ...
