Brain structure changes in size with normal aging, but the rate at which different structures change is controversial. We used magnetic resonance imaging (MRI) performed twice, 4 years apart, to compare rates of age-related size change of the corpus callosum, which has been inconsistently observed to thin with age, with change in the lateral ventricles, which are well established to enlarge. Su...

introduction: the increasing global consensus built on empirical evidence, expresses that the world, is facing a threat from climate change. as a result, this can affect the agricultural sector through its productivity changes and so influence food security in the world. this can be more intuitive for countries that are dependent on agriculture. agriculture is an important sector in iran that p...

This annual article presents information on health care costs by business, households, and government. Households funded 35 percent of expenditures in 1990, government 33 percent, and business, 29 percent. During the last decade, health care costs continued to grow at annual rates of 8 to 16 percent. Burden measures show that rapidly rising costs faced by each sponsor sector are exceeding incre...

BACKGROUND Lack of cancer incidence information for adolescents and young adults led us to describe incidence trends within the young population of 15 to 49 year-olds in urban Shanghai between 1973 and 2005. METHODS During 1973 to 2005, data on 43,009 (45.8%) male and 50,828 (54.2%) female cancer cases aged 15-49 years from the Shanghai Cancer Registry were analyzed. Five-year age-specific ra...

AIM To analyze and interpret incidence and mortality trends of breast and ovarian cancers and incidence trends of cervical and endometrial cancers in Croatia for the period 1988-2008. METHODS Incidence data were obtained from the Croatian National Cancer Registry. Themortality data were obtained from the World Health Organization (WHO) mortality database. Trends of incidence and mortality wer...

Soil water balance has response to climate change and evaluation of soil water change is one of the most important items of climate change impact assessment. GCM outputs under three scenarios were statistically downscaled during 2010~2039 to simulate the potential change of soil water balance in Wangdonggou watershed on the Loess Plateau with WEPP model. GCM predicted a 1.8 to 17.5% increase in...

We examined 4,848 regurgitated digestive pellets of double-crested cormorants (Phalacrocorax auritus) over a 6-year period (1992–97) to estimate annual predation on sport and other fishes in the eastern basin of Lake Ontario. We found more than 51,000 fish of 28 species. Using a model that incorporates annual colony nest counts; fledgling production rates; adult, immature, and young-of-year res...

the aim of this study was to design the base breeding plan in sistani cattle by using of stochastic simulation. for this purpose, three population size (500, 1000, 2000 heads), three levels of herd number (5, 10, 20), two levels of selection intensity (high and low) and two levels of mating method (random and minimum co-ancestry) were combined together and in total 36 scenarios were compared fo...
