WASHINGTON, April 11 (Xinhua) -- Taking a statin before having major elective surgery reduces potentially serious kidney complications, according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology.Each year, more than 230 million major elective surgeries are performed around the world. Unfortunately, many patients who undergo major operations develop kidney injury soon after surgery, often due to decreased blood flow to the kidneys and/or the effects of inflammation.Animal studies suggest that the cholesterol-lowering drugs called statins protect the kidneys from such damage, but whether a similar benefit occurs in humans is uncertain. To investigate, Amber Molnar, University of Western Ontario, and colleagues conducted a population-based retrospective study of all older patients who underwent major elective surgery in the province of Ontario, Canada from 1995 to 2008. Surgeries included cardiac, thoracic, vascular, intra-abdominal, and retroperitoneal procedures.A total of 213,347 patients from 211 hospitals underwent major elective surgery, and 4,020 patients (1.9 percent) developed postoperative kidney injury within two weeks of surgery. A total of 1,173 patients (0.5 percent) required dialysis within two weeks of surgery, and 5,974 patients (2.8 percent) died within a month of surgery.Prior to surgery, 67,941 patients (32 percent) were taking a statin. Patients taking a statin were 20 percent less likely to develop kidney injury, need dialysis, and die compared to patients who were not taking a statin. Also, there was evidence of a dose-effect, with patients on higher potency statins having less kidney injury. In addition, statins were beneficial whether they were started greater than 90 days or less than 30 days prior to surgery."Our study suggests that statin use in older persons results in less kidney injury following major elective surgery and reduces the risk of premature death after surgery," said Molnar, adding that the results warrant further investigation with more rigorous studies, but such trials will be difficult to carry out.

WASHINGTON, May 1 (Xinhua) -- The launch of U.S. space shuttle Endeavour on its final voyage will be no earlier than May 8, after technical problems uncovered last week proved more complex than originally thought, the U.S. National Aeronautics and Space Administration (NASA) announced Sunday.NASA tried to launch Endeavour on Friday on its 25th and final flight to deliver the 2-billion-dollar Alpha Magnetic Spectrometer (AMS) particle detector to the International Space Station. AMS, a particle physics detector, is designed to search for various types of unusual matter by measuring cosmic rays. Its experiments are designed to help researchers study the formation of the universe and search for evidence of dark matter, strange matter and antimatter.The space shuttle Endeavour sits on launch pad 39A as work continues on the shuttle's auxilliary power unit at the Kennedy Space Center in Cape Canaveral, Florida May 1, 2011.However, the launch was called off after engineers detected a failure in one of two heater circuits associated with Auxiliary Power Unit (APU) 1. Heaters are required to keep the APUs' hydrazine from freezing on orbit.NASA hoped Endeavour would lift off on Monday. But further trouble-shooting indicated the glitch was more complicated than officials hoped initially.The failure appears to be a power problem within the aft load control assembly-2, a box of switches controlling power feeds."That basically means the power is not getting out to the heaters that weren't working on launch day," said Space Shuttle Program Launch Integration Manager Mike Moses.

LJUBLJANA, April 12 (Xinhua)-- Slovenian surgeons have successfully developed a new method of breast reconstruction for cancer patients, the Slovenian Press Agency (STA) reported on Tuesday.Surgeons in Ljubljana Central Hospital use a three-dimensional mould to form a new breast from the patient's abdominal fat, and then have the tissue implanted and fixated in the place of the removed breast.The mould making technique, developed by the Ljubljana Faculty of Mechanical Engineering, uses a laser to make an exact imprint of the healthy breast, which is then used to make a mirror-image three-dimensional mould for the reconstruction.That is the first in the world to help woman patients overcome embarrassment of losing their breast after mastectomy, according to the report.Speaking of the effect of the treatment, Uros Ahcan, head of plastic surgery ward in Ljubljana Central Hospital , said that the reconstructed breast is as symmetrical as possible with the healthy breast.The latest breast reconstruction method has an advantage over artificial implants, because a breast reconstructed from adipose tissue grows and shrinks in case of weight gain and weight loss. In addition, the tissue has the same temperature as the rest of the body, the STA quoted Ahcan as saying.The Ljubljana Central Hospital have done eight breast reconstruction operations for cancer patients, all of them were successful, with ten more planned in the coming weeks, the report added.Some 1,200 Slovenian women are reportedly diagnosed with breast cancer annually. About 70 percent of the patients hope to have breast reconstruction after mastectomy.

PYONGYANG, Feb. 14 (Xinhua) -- Kim Yong Nam, president of the Presidium of the Supreme People's Assembly of the Democratic People's Republic of Korea (DPRK), met Chinese Minister of Public Security Meng Jianzhu here on Monday.Kim said it was the consistent stand of the Worker's Party of Korea (WPK) and the government and the firm will of the people to develop the traditional DPRK-China friendship generation after generation.The DPRK is sincerely happy to see the great achievement China has made and wish that the Chinese people make even more progress, Kim said.Meng, also a State Councilor, said the traditional friendship between the two neighboring countries has strengthened through the ages. He expressed his expectations of inheriting the friendship, deepening communications and cooperation in various areas and promoting the China-DPRK friendship.Ri Yong Ho, Presidium of Political Bureau of Central Committee of WPK and chief of the Korean People's Army General Staff, also met Meng on the same day.Ju Sang Song, a member of the Political Bureau of Central Committee of the WPK and Minister of People's Security, met Meng on Sunday. The two achieved consensus on making more efforts to develop cooperation and communications on public security to make active contributions to the traditional China-DPRK friendship. An agreement on cooperation between the the two security ministries was signed after the meeting.Meng arrived at Pyongyang on Sunday at the invitation of Ju Sang Song.

LOS ANGELES, April 12 (Xinhua) -- With the help of NASA Telescopes, astronomers have uncovered one of the youngest galaxies in the distant universe, with stars that formed 13.5 billion years ago, the Jet Propulsion Laboratory (JPL) announced on Tuesday.The finding addresses questions about when the first galaxies arose, and how the early universe evolved, JPL noted in a press release.Infrared data from both the Hubble Space Telescope and the post- coolant, or "warm," phase of NASA's Spitzer Space Telescope mission revealed that the galaxy's stars are quite mature, which means they must have formed when the universe was just a toddler, said JPL in Pasadena, Los Angeles.This challenges theories of how soon galaxies formed in the first years of the universe and could even help solve the mystery of how the hydrogen fog that filled the early universe was cleared, according to astronomers involved in the study.This galaxy is not the most distant ever observed, but it is one of the youngest to be observed with such clarity, JPL said.Normally, galaxies like this one are extremely faint and difficult to study, but, in this case, nature has provided the astronomers with a cosmic magnifying glass, JPL said.The galaxy's image is being magnified by the gravity of a massive cluster of galaxies parked in front of it, making it appear 11 times brighter. This phenomenon is called gravitational lensing."Without this big lens in space, we could not study galaxies this faint with currently available observing facilities," said Eiichi Egami of the University of Arizona in Tucson. "Thanks to nature, we have this great opportunity to see our universe as it was eons ago."The findings may help explain how the early universe became " reionized," according to JPL."Seeing a galaxy as it appeared near the beginning of the universe is an awe-inspiring feat enabled by innovative technology and the fortuitous effect of gravitational lensing," Jon Morse, NASA's Astrophysics Division director at the agency's headquarters in Washington, said in the release."Observations like this open a window across space and time, but more importantly, they inspire future work to one day peer at the stars that lit up the universe following the big bang."
