| Human Stem Cells Delay Start Of Lou Gehrig's Disease In Rats | | Posted Thursday, October 19, 2006 2:59:14 AM by Blog57 Team | | Researchers at Johns Hopkins have shown that transplanting human stem cells into spinal cords of rats bred to duplicate Lou Gehrig's disease delays the start of nerve cell damage typical of the disease and slightly prolongs life. The grafted stem cells develop into nerve cells that make substantial connections with existing nerves and do not themselves succumb to Lou Gehrig's, also known as amyotrophic lateral sclerosis (ALS). The study is published in this week's issue of Transplantation. .... | |

| | | Stripped to the bone | | Posted Saturday, September 09, 2006 5:02:48 PM by Blog57 Team | | A man holds his own skin over his arm. He is brandishing a scalpel and a pair of scissors, strongly suggesting he has just mutilated himself. The 8ft bronze statue - Saint Bartholomew, Exquisite Pain - is the latest work from Britain's leading modern artist Damien Hirst. He is joining forces with the Duke of Devonshire for a Sotheby's exhibition of modern sculpture at Chatsworth in Derbyshire. St Bartholomew was one of the 12 apostles who, tradition has it, was skinned alive in Armenia. Hirst said of his latest creation: "St Bartholomew comes from woodcuts and etchings I remember seeing when I was younger. As he was a martyr who was skinned alive, he was often used by artists and doctors to show human anatomy." Hirst said his work was a homage to Tim Burton's gothic 1990 film Edward Scissorhands, starring Johnny Depp.... | |

| | | Ultrasound can affect brain development | | Posted Wednesday, August 09, 2006 10:58:48 AM by Blog57 Team | | WASHINGTON, D.C. -- Exposure to ultrasound can affect fetal brain development, a new study suggests. But researchers say the findings, in mice, should not discourage pregnant women from having ultrasound scans for medical reasons.When pregnant mice were exposed to ultrasound, a small number of nerve cells in the developing brains of their fetuses failed to extend correctly in the cerebral cortex."Our study in mice does not mean that use of ultrasound on human fetuses for appropriate diagnostic and medical purposes should be abandoned," said lead researcher Pasko Rakic, chairman of the neurobiology department at Yale University School of Medicine.However, he added in a telephone interview, women should avoid unnecessary ultrasound scans until more research has been done.Dr. Joshua Copel, president-elect of the American Institute of Ultrasound Medicine, said his organization tries to discourage "entertainment" ultrasound, but considers sonograms important when there is a medical benefit."Anytime we're doing an ultrasound we have to think of risk versus benefit.... | |

| | | Emmy nominations full of surprises | | Posted Saturday, July 08, 2006 4:56:04 AM by Blog57 Team | | Dr. Grey, paging Dr. Meredith Grey: We're crazy for your Anatomy! President Allen? We love you, you loser! Grace, honey, you've still got it, no matter what anyone says. You too, President Bartlet. Those were just a few of the surprising disses and kisses sent out to some of TV's most popular shows this morning when Julia Louis-Dreyfus and Brad Garrett announced the 2006 Emmy nominations. Louis-Dreyfus herself looked a little stunned when Garrett - formerly the hangdog brother of Ray Romano's Raymond and soon to be the husband of Joely Fisher in fall's new “Till Death" - read her name from the list of best comedy actress nominee. Definitively breaking the “Seinfeld" curse, the ex-Elaine grabbed one of the five academy nods for her hilarious work as a divorced soccer mom in CBS' “The New Adventures of Old Christine," which started at midseason and has aired just 13 episodes.... | |
