WASHINGTON, May 17 (Xinhua) -- A variation in a gene involved in regulating cholesterol in the bloodstream also appears to affect progesterone production in women, making it a likely culprit in a substantial number of cases of their infertility, a new study from Johns Hopkins University researchers suggests.The Hopkins group has also developed a simple blood test for this variation of the scavenger receptor class B type 1 gene ( SCARB1) but emphasized there is no approved therapy yet to address the problem in infertile women.Following up studies in female mice that first linked a deficiency in these receptors for HDL -- the so-called "good" or " healthy" cholesterol -- and infertility, researchers report finding the same link in studies of women with a history of infertility.The findings has been published on-line this week in the journal Human Reproduction.If the new study's findings hold up on further investigation, the John Hopkins team says they not only will offer clues into a genetic cause of some infertility, but could also lead to a treatment already shown to work in mice."Infertility is fairly common and a lot of the reasons for it are still unknown," warns endocrinologist Annabelle Rodriguez, an associate professor of medicine at the Johns Hopkins University School of Medicine and the lead author. "Right now, the benefit of this research is in knowing that there might be a genetic reason for why some women have difficulty getting pregnant. In the future, we hope this knowledge can be translated into a cure for this type of infertility."

BEIJING, March 15 (Xinhuanet) -- Chris Poole, the 22-year-old founder of 4Chan.org, criticized Facebook's approach and spoke up for online anonymity at South by Southwest Interactive in Austin, Texas, according to media reports Tuesday.Poole called out early in his keynote speech at the huge Austin tech event, referencing this Zuckerberg quote from David Kirkpatrick’s book "The Facebook Effect": "Having two identities for yourself is an example of a lack of integrity.""Anonymity is authenticity; it allows you to share in a completely unfiltered way," Poole countered. "It allows you to play in ways, you might not if people knew who you are.”Losing the ability to be anonymous on the Internet is, "a kind of loss of the innocence of youth," Poole said, crediting 4chan’s culture-infiltrating creativity to anonymity. "You can’t make mistakes,“ and then leave them behind, like the olds did pre-Facebook. If your mistakes ever made it to the Internet, they’re with you wherever you go.Poole — known by the 4chan handle "moot" — was to promote his new meme-generating venture, Canvas, still in beta testing.Launched for anime enthusiasts in 2003, 4chan is one of the most popular image-sharing bulletin boards on the Internet, with most of that traffic hitting 4chan’s notorious "random" image board, the /b/ board.

LOS ANGELES, April 2 (Xinhua) -- The United States could soon be faced with an epidemic of Non-Alcoholic Fatty Liver Disease ( NAFLD), one of the major contributing factors of chronic liver disease (CLD), the American Association for the Advancement of Science (AAAS) reported Saturday.If the current rates of obesity and diabetes continue for another two decades, the prevalence of NAFLD in the U.S. is expected to increase by 50 percent in 2030, AAAS said.The prediction is based on pre-existing clinical survey data over a 10 year period (1988-1994, 1999-2004 and 2005-2008), which included 39,500 adults from three survey cycles, according to the AAAS.Over the three cycles, the prevalence of NAFLD doubled from 5. 51 percent to 11 percent respectively. Furthermore, during the first survey cycle (1988-1994) 46.8 percent of all CLD's was related to NAFLD but by 2005-2008 this had increased to 75.1 percent. In addition, the prevalence of obesity and diabetes, the two key risk factors for NAFLD also steadily increased."If the obesity epidemic is anything to go by, the U.S. NAFLD epidemic may have a ripple effect worldwide," said Mark Thursz, Vice Secretary of the European Association for the Study of the Liver. "It is imperative that health systems continue to drive effective educational programs to reinforce awareness among the general public to alert them of the risks of obesity and promote the importance of diet and exercise."Non-alcoholic fatty liver disease is fast becoming one of the top concerns for clinicians due to the obesity epidemic and it's potential to progress to advanced liver disease which significantly impacts on overall liver-related mortality, Thursz said in remarks published by AAAS' website EurekAlert.org.NAFLD, considered as one of the major causes of morbidity and mortality worldwide, is the term used to describe fat build-up in liver cells in people who do not drink alcohol excessively. The disease is the most common persistent liver disorder in Western countries with an estimated overall prevalence of 20-30 percent, according to AAAS.NAFLD encompasses a spectrum of liver disease associated with insulin resistance, diabetes and obesity and as such people most at risk of NAFLD are those who are obese, have insulin resistance associated with diabetes, high blood pressure and cholesterol.

BEIJING, Feb. 1 (Xinhua) -- A ceremony with a bonfire and firecrackers was held Tuesday night in the new seat of a quake-leveled county in southwest China's Sichuan Province, prior to the Chinese Lunar New Year on Thursday.The Lunar New Year, or Spring Festival, is the most important Chinese holiday. It is a time for family reunions, gift giving and fireworks.It will be even merrier for the survivors of the Wenchuan earthquake in 2008, who just moved into their new homes in the new town.The earthquake survivors are preparing for the first Spring Festival in their new homes.Xia Tianfeng of Beichuan County, Mianyang City, is sticking red paper decorations onto the windows of her new house for good luck in the New Year."We finally have our new house. Why wouldn't I be happy?" asked Xia.She and her family lived in a makeshift house for two years before moving into their new house one month ago.Dong Depa, 43, and his family moved into their new house in Yingxiu Town, the epicenter of the quake, five days ago."I can pay off the debt incurred to build the house in two years," said Dong, who spent only 30,000 yuan (4,541 U.S. dollars) for the house's construction and decoration, with the rest being shouldered by the government.Dong lost his two children in the quake but he and his wife have since had another child, a son."Last year, we spent the Spring Festival in the dormitory of the brick factory where I work as a cook. Now we can finally enjoy the festival in our own home," said Dong, unable to conceal his joy.Xia told Xinhua the ceremony for the new county seat was the real taste for a happy new year.Reconstruction has finished in the quake-hit zones in Sichuan, with most survivors now in their new houses.In Beichuan County alone, 96.5 percent of the survivors already have their new house.The new county seat is located in Yongchang Town, about 23 kilometers from the quake-leveled old one.The 8.0-magnitude earthquake struck southwest China on May 12, 2008, leaving about 80,000 people dead or missing.Waving goodbye to their temporary barracks, 7,397 households have been allocated new apartments, among which 3,504 households were former Beichuan residents, while others were from different Wenchuan earthquake-hits regions."The new apartment has already been simply decorated by the time I received the door key. With our new furniture, we can wait no longer to move into the home," said 45-year-old Xie Xinghe, a former resident of Beichuan.Including 50,000 yuan (about 7,575 U.S. dollars) in loans, Xie paid a preferential price of 79,600 yuan (about 12,000 U.S dollars) for the 100 square meter new apartment.Losing his only son in the earthquake, Xie and his wife adopted a one-year-old boy."It is the child who brings me new hope for the future," Xie said. Following the Lunar New Year celebration in his new home, Xie will try his best to work for some years to pay back the loan and save money to ensure a better education for his son."It is such magic to build a new town within three years, even so anywhere around the world. And we see it now," said Xu Zhenxi, director with the headquarter of new town program of Beichuan, which is supported by east China's Shandong Province.From May 25, 2009 to September 25, 2010, Shandong Province supported the new Beichuan county seat project, which was completed within 15 months.

LOS ANGELES, April 2 (Xinhua) -- People taking antidepressants may be more likely to develop thicker arteries which may raise the risk of heart disease and stroke, a new study suggests.Depression can heighten the risk for heart disease, but the effect of antidepressant use is separate and independent from depression itself, according to the study make public by the American Association for the Advancement of Science (AAAS) on Saturday.The data suggest that antidepressants may combine with depression for a negative effect on blood vessels, said study first author Amit Shah, MD, a cardiology fellow at Emory University School of Medicine.Study findings will be presented on April 5 at the American College of Cardiology meeting in New Orleans, according to the AAAS.The study included 513 middle-aged male twins who both served in the U.S. military during the Vietnam War. Twins are genetically the same but may be different when it comes to other risk factors such as diet, smoking and exercise, so studying them is a good way to distill out the effects of genetics.Researchers measured carotid intima-media thickness - the thickness of the lining of the main arteries in the neck -- by ultrasound. Among the 59 pairs of twins where only one brother took antidepressants, the one taking the drugs tended to have higher carotid intima-media thickness (IMT), even when standard heart disease risk factors were taken into account.The effect was seen both in twins with or without a previous heart attack or stroke. A higher level of depressive symptoms was associated with higher IMT only in those taking antidepressants."One of the strongest and best-studied factors that thickens someone's arteries is age, and that happens at around 10 microns per year," Shah said. "In our study, users of antidepressants see an average 40 micron increase in IMT, so their carotid arteries are in effect four years older."Antidepressants' effects on blood vessels may come from changes in serotonin, a chemical that helps some brain cells communicate but also functions outside the brain, Shah said."I think we have to keep an open mind about the effects of antidepressants on neurochemicals like serotonin in places outside the brain, such as the vasculature. The body often compensates over time for drugs' immediate effects," Shah said. " Antidepressants have a clinical benefit that has been established, so nobody taking these medications should stop based only on these results. This isn 't the kind of study where we can know cause and effect, let alone mechanism, and we need to see whether this holds up in other population groups."
