Successful Neurosurgery With Transcranial MR-Guided High-Intensity Focused Ultrasound
The Magnetic Resonance Center of the University Children"s Hospital Zurich has achieved a world first break through in MR-guided, non-invasive neurosurgery. Ten patients have been successfully treated by means of transcranial high-intensity focused ultrasound. This fully non-invasive procedure opens new horizons for neurosurgery and the treatment of different neurological brain disorders.

Obama Urges Swift Confirmation Of Sotomayor; GOP Mulls Opposition Strategy
President Obama on Tuesday in his official announcement of his nomination of Judge Sonia Sotomayor of the Second Circuit Court of Appeals to the Supreme Court emphasized what he called her "extraordinary journey" from a modest background to the top of the judiciary, launching a "confirmation battle that he hopes to wage over biography more than ideology," the New York Times reports. If confirmed, Sotomayor would be the first Hispanic and the third woman to serve on the court, as well as the sixth of the court"s current members with a Roman Catholic background, the Times reports (Baker/Zeleny, New York Times, 5/27). Sotomayor would replace retiring Justice David Souter, who typically is a liberal vote on social issues, the Wall Street Journal reports. Therefore, the addition of Sotomayor would not likely change the ideological balance of the court (Bravin/Koppel, Wall Street Journal, 5/27). The Washington Post reports Obama in his remarks cast Sotomayor "as the embodiment of the qualities he seeks in a judge," including superior intelligence, an understanding of the limited role of the judiciary and what he called "an understanding of how the world works and how ordinary people live" (Barnes/Fletcher, Washington Post, 5/27). The president said he wants Sotomayor to be confirmed before the Senate leaves in August for its summer recess, so she can join the court in time for its September review of potential cases. White House Press Secretary Robert Gibbs said that the Senate has "ample time" to complete the confirmation process, as the average time span is 72 days and there are 74 until the recess (Koffler, Roll Call, 5/26). Senate Judiciary Committee Chair Patrick Leahy (D-Vt.) praised Obama"s decision, calling Sotomayor"s record "exemplary" and her nomination "historic." Leahy noted that both former President George H.W. Bush and former President Clinton nominated Sotomayor to federal judgeships, adding, "She has been nominated by both Democratic and Republican presidents, and she was twice confirmed by the Senate with strong, bipartisan support" (Stanton, Roll Call, 5/26).Rulings on Abortion Rights Throughout her career as a federal judge, Sotomayor has not issued what are considered major decisions regarding abortion rights, although her record on cases involving civil and social rights issues appear "more liberal than not," according to the New York Times (Liptak, New York Times, 5/27). Politico reports that Sotomayor has ruled in favor of antiabortion-rights groups in two cases. The first case occurred in 2002 when she sided with the Bush administration in its efforts to implement the "global gag rule," which banned federal funding for international family planning groups that offer abortion services or information with their own funds. Sotomayor ruled that the government had the right to decide how to spend its funding. In 2004, Sotomayor ruled in favor of antiabortion-rights protesters who alleged that they were brutalized while being arrested in West Hartford, Conn. (Gerstein/Javers, Politico, 5/26). Gibbs said that Obama did not ask Sotomayor about issues related to abortion during her vetting and there was "no litmus test" on abortion-rights issues (Koffler, Roll Call, 5/26).Obama"s announcement was well-received by many groups that support abortion rights. NARAL Pro-Choice America President Nancy Keenan said the group is anticipating more information about Sotomayor"s views on abortion rights and the right to privacy. She added that the group is "encouraged by the strong support she receives from her peers and other legal scholars and the fact that the Senate has twice confirmed her for federal judgeships" (Posner, Congress Daily, 5/26). Kim Gandy, president of the National Organization of Women, said that Sotomayor "brings a lifelong commitment to equality, justice and opportunity, as well as the respect of her peers, unassailable integrity and a keen intellect informed by experience." Gandy added that Obama "said he wanted a justice with "towering intellect" and a "common to

RCN Calls For EU Agreement On Sharps Injuries To Be Implemented Quickly
The Royal College of Nursing welcomed the signing of a joint agreement by European Federation of Public Service Unions (EPSU) and the European Hospital and Healthcare Employers Association (HOSPEEM). This is an EU-wide agreement which the RCN has played a key role in bringing about to prevent one million medical sharps injuries per year. Dr Peter Carter, Chief Executive of the Royal College of Nursing (RCN), said:

The Evolutionary Foundation Of Genomic Imprinting In Lower Vertebrates

A Chinese scientist group working in College of Life Science, Zhejiang University, has shown that, as mammalian Igf2 CpG island, goldfish Igf2 CpG island has a parental differentially methylated region (DMR). These results indicate that the evolutionary foundation of genomic imprinting exists in lower vertebrates and genomic imprinting should not be considered as a unique evolutionary event of mammals. The study is reported in volume 54 (Issue 8, April, 2009) of Chinese Science Bulletin. Genomic imprinting has been identified in eutherians, marsupials and flowering plants, but no endogenous imprinted gene has been reported in other vertebrates and invertebrates. Therefore, genomic imprinting is thought a unique phenomenon of placental mammals and a regulatory mechanism to keep a balance of supply and demand for maternal nutrients between mother and fetus in mammalian species. However, how genomeic imprinting was originated, established and maintained during vertebrate evolution remains unclear. In this study, the authors examined the methylation status of the teleost homologue of mammalian imprinting gene Igf2 during gametogenesis. Their results showed that, as mammalian Igf2 CpG island, goldfish Igf2 CpG island was a parental differentially methylated region that was hypermethylated in sperm but unmethylated in eggs. The authors also indicated that, unlike mammalian imprinting gene DMR, the unmethylated DMRñ€€of maternal allele could not resist methylation reprogramming and started de novo methylation at the cleavage stage, while the paternal Igf2 allele appeared to maintain its paternal methylation imprints during embryogenesis. These results suggested that the parent-specific methylation of goldfish Igf2 DMR might be a primitive genomic imprinting in the early period of vertebrate evolution. The investigation "provided the first molecular evidence that the evolutionary foundation of genomic imprinting exists in lower vertebrates", said one of the journal reviewers. This work was supported by of the National Natural Science Foundation of China (Grant No. 30430370) and the State Key Basic Research Project of China (2004CB117401).
