SEOUL, April 12 (Xinhua) -- South Korea has downgraded its alert level for foot-and-mouth disease (FMD) one notch as the disease has practically come to an end, the Ministry for Food, Agriculture, Forestry and Fisheries said Tuesday.The ministry said that it lowered the alert level from "orange" to "yellow," the second-lowest status in the four-tiered alert system, as no additional burial of livestock has occurred in three weeks after the last case in Hongseong, South Chungcheong Province, on March 21.The country dropped the alert level from the highest level of " red" to "orange" on March 24.The highly contagious animal disease, first confirmed on Nov. 29, has forced the country to cull more than 3.47 million livestock, mostly pigs and cattle, resulting in losses of 3 trillion won (2.6 billion U.S. dollars).The ministry, meanwhile, said that 670 animal quarantine experts will continue to decontaminate livestock farms once every week and keep close watch to see if any animals become sick.

WASHINGTON, April 6 (Xinhua) -- A study led by researchers at the University of Michigan (U-M) showed in animal studies that new cancer drug compounds they developed shrank tumors, with few side effects.The study, done in two mouse models of human cancer, looked at two compounds designed to activate a protein that kills cancer cells. The protein, p53, is inactivated in a significant number of human cancers. In some cases, it is because another protein, MDM2, binds to p53 and blocks its tumor suppresser function. This allows the tumor to grow unchecked. The new compounds block MDM2 from binding to p53, consequently activating p53."For the first time, we showed that activation of p53 by our highly potent and optimized MDM2 inhibitors can achieve complete tumor regression in a mouse model of human cancer," says lead study author Shaomeng Wang, director of the Cancer Drug Discovery Program at the U-M Comprehensive Cancer Center.Wang presented the study Wednesday at the American Association for Cancer Research 102nd annual meeting.Many traditional cancer drugs also activate p53 but they do so by causing DNA damage in both tumor cells and normal cells, causing side effects. These new MDM2 inhibitors activate p53 while avoiding the DNA damage common with other drugs. In this study, which was done in collaboration with Ascenta Therapeutics and Sanonfi-Aventis, researchers showed that these new drugs shrank tumors without significant side effects.Because p53 is involved in all types of human cancer, the new drug has potential to be used in multiple types of cancer. Further, the researchers also identified certain markers in tumors that predict which ones will be particularly sensitive to the MDM2 inhibitor, which would allow physicians to target the drug only to patients most likely to benefit.

BEIJING, May 10 (Xinhuanet) -- Autism spectrum disorder may be under diagnosed and under reported worldwide and rigorous screening is needed for accurate estimates, said researchers in Monday's American Journal of Psychiatry.Researchers from the Yale Child Study Center, George Washington University and other leading institutions screened every child aged 7 to 12 in Ilsan district of the city of Goyang, a community of 488,590 in South Korea, and found more than two-thirds of ASD cases in the mainstream school population unrecognized and untreated.They estimated the prevalence of ASD in South Korea to be 2.64 percent, or approximately 1 in 38 children.The figure is more than twice the rate usually reported in the developed world. Even that rate, about 1 percent, has been climbing rapidly in recent years — from 0.6 percent in the United States in 2007, for example.“From the get-go we had the feeling that we would find a higher prevalence than other studies because we were looking at an understudied population: children in regular schools,” said the lead researcher, Dr. Young-Shin Kim, a child psychiatrist and epidemiologist at the Yale Child Study Center.By contrast, other research groups measure autism prevalence by examining and verifying records of existing cases kept by health care and special education agencies, but leaving out many children whose parents and schools have never sought a diagnosis.Kim said the researchers concluded autism prevalence estimates worldwide may increase if rigorous screening and comprehensive population studies are used to produce prevalence estimates.But it is suggested the findings did not mean that the actual numbers of children with autism were rising, simply that the study was more comprehensive than previous ones.
