objectives and background: mutation directed inactivation of the tumor suppressor gene p53 have been found incountries with high frequency for hepatocellular carcinomas (hccs). our goal in the present study was screening of the p53 gene in tumor tissues from hcc affected individuals in southwest iran for putative mutations in exons 7 and 8 that are known as hot spot regions. materials & met...
The mountains of High Mountain Asia serve as an important source water for roughly one billion people living downstream. This research uses 15 years dynamically downscaled precipitation produced by the Weather Research and Forecasting (WRF) model to delineate contrasts in characteristics events between regions dominated Indian Summer Monsoon (ISM) versus westerly disturbances during cool season...
With intensifying demands for food and biofuels, a critical threat to biodiversity is agricultural expansion into native tropical ecosystems. Tropical agriculture, particularly intensive agriculture, often supports few native organisms, and consequently has been largely overlooked in conservation planning; yet, recent work in the Neotropics demonstrates that tropical agriculture with certain fe...
Originating from Asia, the brown marmorated stink bug (BMSB) is a significant pest of horticultural/agricultural crops, grapes, woody ornamental and herbaceous plants, and is also a nuisance to people, due to its overwintering behavior in human habitation. The global range of this pest is steadily increasing and previous predictions of environmental suitability have shown New Zealand to be high...
the collapse of the soviet :union: provided an extraordinary opportunity for china to enforce political and economic process in the central asian region. proximity of the border of china and the central asian countries with rapid economic growth of china, have imposed certain conditions on central asian countries' relations with it. in general, bilateral relations between china and the cou...
Abstract Precipitation is crucial for life and the ecological environment in Asian drylands. This study investigated precipitation trends drylands previous four decades simulated its possible linkage with snow cover reduction over Tibetan Plateau. The results show that has been increasing contributing to wetter conditions can be attributed deepened quasi-stationary wave trough around Lake Balkh...
Despite much attention, history of sheep (Ovis aries) evolution, including its dating, demographic trajectory and geographic spread, remains controversial. To address these questions, we generated 45 complete and 875 partial mitogenomic sequences, and performed a meta-analysis of these and published ovine mitochondrial DNA sequences (n = 3,229) across Eurasia. We inferred that O. orientalis and...
Micronutrient deficiency, whether clinical or subclinical, may affect growth, cognition and reproductive performance. In pregnant women moderate to severe deficiencies of iron, zinc and folic acid have been shown to increase risk of low birth weight, pregnancy complications and birth defects. Any attempt to introduce a micronutrient supplementation programme during pregnancy must be based on ad...
Taxonomic over-splitting of extinct or endangered taxa, due to an incomplete knowledge of both skeletal morphological variability and the geographical ranges of past populations, continues to confuse the link between isolated extant populations and their ancestors. This is particularly problematic with the genus Equus. To more reliably determine the evolution and phylogeographic history of the ...
