BEIJING, April 12 (Xinhuanet) -- A new research indicats taking vitamin D could ward off vision loss from age-related macular degeneration (AMD) in women younger than 75, according to media reports on Tuesday.In the research, women under 75 who consumed sufficient vitamin D cut their risk of developing early age-related AMD, a leading cause of vision loss and blindness, by 59 percent when compared to women with vitamin D-poor diets.Researchers found that vitamin D levels among patients in the study were most affected by the amount of vitamin D they consumed, through certain fish, dairy, eggs, and leafy greens, not by the amount of outdoor exposure they had. Considering many Americans are actually deficient in vitamin D, this study may offer one more reason for women to include vitamin D-rich foods in the diet, said the lead author on the study, Amy Millen of the University of Buffalo.

JERUSALEM, March 31 (Xinhua) -- Two researchers at the Hebrew University (HU) of Jerusalem have been honored with a prestigious award for their study of the connection between several inflammatory diseases, cancer and bacteria.Medical faculty members, Dr. Eli Pilarsky and Prof. Sigal Ben- Yehuda, won this year's Sir Zelman Cowen Universities Fund prize that recognizes significant achievement in the field of medicine.The prize committee noted the impressive contributions of Pilarsky and Ben-Yehuda in understanding complex diseases like cancer and antibiotic-resistant infections, and, in a first, decided to award the two scientists this year.Pilarsky told Xinhua that his research deals with the connection between chronic inflammatory diseases like hepatitis, and the development of cancer cells."The relevance of this discovery is that we were able to establish the link between the molecules secreted with such inflammations and the proliferation of cancer cells," Pilarsky explained, noting that "we discovered that the inflammation favors the cancer cells' growth, and now we are trying to find a way to manipulate these molecules to stop the cancer cells from appearing. ""The importance of these findings lies in the fact that 20 percent of the world's cancer cases are attributed to inflammation processes," Pilarsky pointed out.

JINAN, May 14 (Xinhua) -- Chinese scientists said Saturday that they have found a new species of giant theropod dinosaur in the eastern province of Shandong.The new species, described as a close relative of Tyrannosaurus rex (T. rex), has been named "Zhuchengtyrannus magnus". Paleontological experts found it has unique upper jawbones after examining the skull and jawbones discovered in the city of Zhucheng.It was estimated to be about 11 meters long and 4 meters tall, weighing close to 7 tonnes."We discovered two kinds of tyrannosaurus fossils here and the identity of the other one still remains unclear," said Xu Xing, a researcher at the Institute of Vertebrate Paleontology and Paleoanthropology under the Chinese Academy of Sciences."We've named the new genus Zhuchengtyrannus magnus, which means the 'Tyrant from Zhucheng' because the bones were found in Zhucheng," Xu said.The bones were a few centimeters smaller than the similar bones in the largest T. Rex specimen, so there was no doubt that Zhuchengtyrannus was a huge tyrannosaur, Xu said.According to Xu, Zhuchengtyrannus magnus belonged to a specialized group of gigantic theropods called tyrannosaurines which existed in North America and eastern Asia during the Late Cretaceous Period that dated back about 65 to 99 million years.All tyrannosaurs were carnivorous, bipedal animals that generally had small arms and large skulls. Among the tyrannosaurs, the tyrannosaurines were the largest and characterized by having just two fingers on each hand and large powerful jaws to deliver a bone crushing bite. They were likely both predators and scavengers.The fossil quarry in Zhucheng contains one of the largest concentrations of dinosaur bones in the world. At least 10 dinosaur species have been found in three rounds of excavations since the 1960s, including Tyrannosaurus and Hadrosaurs.
