(PhysOrg.com) -- New research suggests that blocking the activity of a protein in the blood could offer powerful protection against some skin cancers. http://www.physorg.com/news154096551.html Medicine & Health Tue, 17 Feb 2009 12:36:27 EST news154096551 The social environment at swimming pools appears to be related to sun safety behaviors of outdoor pool staff, according to a report in the February issue of Archives of Dermatology, one of the JAMA/Archives journals. http://www.physorg.com/news154025532.html Medicine & Health Mon, 16 Feb 2009 16:52:42 EST news154025532 People with a family history of melanoma may have a greater risk of developing Parkinson's disease, according to a study released today that will be presented at the American Academy of Neurology's 61st Annual Meeting in Seattle, April 25 to May 2, 2009. http://www.physorg.com/news154024656.html Medicine & Health Mon, 16 Feb 2009 16:38:04 EST news154024656 Scientists at the Gladstone Institutes of Cardiovascular Disease (GICD) have found that an enzyme associated with the synthesis of fat in the body is also an element in healthy skin and hair. http://www.physorg.com/news153736642.html Chemistry Fri, 13 Feb 2009 08:38:04 EST news153736642 (PhysOrg.com) -- A little more than a year after University of Wisconsin-Madison scientists showed they could turn skin cells back into stem cells, they have pulsating proof that these "induced" stem cells can indeed form the specialized cells that make up heart muscle. http://www.physorg.com/news153679352.html Medicine & Health Thu, 12 Feb 2009 16:42:59 EST news153679352 The simple recipe scientists earlier discovered for making adult stem cells behave like embryonic-like stem cells just got even simpler. A new report in the February 6th issue of the journal Cell, a Cell Press publication, shows for the first time that neural stem cells taken from adult mice can take on the characteristics of embryonic stem cells with the addition of a single transcription factor. Transcription factors are genes that control the activity of other genes. http://www.physorg.com/news153059473.html Biology Thu, 05 Feb 2009 12:31:44 EST news153059473 Vacationing at the shore led to a 5 percent increase in nevi (more commonly called "moles") among 7-year-old children, according to a paper published in Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research. http://www.physorg.com/news152858487.html Medicine & Health Tue, 03 Feb 2009 04:46:33 EST news152858487 In the largest study to date to evaluate fluorodeoxyglucose positron emission tomography combined with computed tomography (FDG-PET/CT) in the initial staging of inflammatory breast cancer (IBC), researchers were able to identify the precise location and extent of metastasis (spread of disease), offering the potential for a better prognosis for patients with this rare, but aggressive form of breast cancer. http://www.physorg.com/news152806026.html Medicine & Health Mon, 02 Feb 2009 14:07:55 EST news152806026 Since the cloning of Dolly the Sheep over a decade ago, somatic cell nuclear transfer (SCNT) has been considered a promising way to generate human, patient-specific stem cells for therapeutic applications. The shortage of human donor eggs has led to efforts to substitute animal oocytes. http://www.physorg.com/news152802480.html Biology Mon, 02 Feb 2009 13:08:34 EST news152802480 A component of DNA that can both stimulate and suppress the immune system, depending on the dosage, may hold hope for treating cancer and infection, Medical College of Georgia researchers say. http://www.physorg.com/news152285494.html Medicine & Health Tue, 27 Jan 2009 13:32:07 EST news152285494 (PhysOrg.com) -- A McGill-led study has found that the perception of speech sounds is modified by stretching facial skin in different directions.

The findings mark an advancement in wound healing and may be used to pioneer a method of organ reconstruction. The study is published in Artificial Organs, official journal of the International Federation for Artificial Organs (IFAO), the The International Faculty for Artificial Organs (INFA) and the International Society for Rotary Blood Pumps (ISRBP). http://www.physorg.com/news151166956.html Medicine & Health Wed, 14 Jan 2009 14:49:16 EST news151166956 (PhysOrg.com) -- Thousands of painstakingly handwritten books produced in medieval Europe still exist today, but scholars have long struggled with questions about when and where the majority of these works originated. Now a researcher from North Carolina State University is using modern advances in genetics to develop techniques that will shed light on the origins of these important cultural artifacts. http://www.physorg.com/news150976551.html Chemistry Mon, 12 Jan 2009 09:55:51 EST news150976551 Just after 5 p.m. doors rattle shut and feet begin to shuffle past the narrow lab where Karim Si-Tayeb sits hunched over a microscope, all but invisible to the scientists leaving the Medical College of Wisconsin. Si-Tayeb has already worked eight hours and will work five more, eyes locked on the living cells in his care. Under the microscope, their tiny colonies resemble constellations of tightly packed stars. They carry his ambition. http://www.physorg.com/news150295895.html Biology Sun, 04 Jan 2009 12:51:35 EST news150295895 (PhysOrg.com) -- When neurons started dying in Clive Svendsen's lab dishes, he couldn't have been more pleased.The dying cells - the same type lost in patients with the devastating neurological disease spinal muscular atrophy - confirmed that the University of Wisconsin-Madison stem cell biologist had recreated the hallmarks of a genetic disorder in the lab, using stem cells derived from a patient. By allowing scientists the unparalleled opportunity to watch the course of a disease unfold in a lab dish, the work marks an enormous step forward in being able to study and develop new therapies for genetic diseases. http://www.physorg.com/news149090319.html Medicine & Health Sun, 21 Dec 2008 13:58:39 EST news149090319 Researchers at Northwestern University have discovered a critical new way a man can transmit the HIV virus to a woman. http://www.physorg.com/news148656888.html Medicine & Health Tue, 16 Dec 2008 13:34:48 EST news148656888 Some patients wish they had a second skin - for instance because their own skin has been burnt in a severe accident. But transplanting skin is a painstaking task, and a transplant that has to cover large areas often requires several operations. Medical scientists have therefore been trying for a long time to grow artificial tissue. This "artificial skin" would allow them to treat these patients better and faster. http://www.physorg.com/news148054025.html Biology Tue, 09 Dec 2008 14:07:05 EST news148054025 Stem cells derived from bone marrow may serve as a novel therapeutic option to treat a disease called epidermolysis bullosa (EB), a disorder characterized by extraordinarily fragile skin, according to a study prepublished online in Blood, the official journal of the American Society of Hematology. http://www.physorg.com/news147618795.html Medicine & Health Thu, 04 Dec 2008 13:13:15 EST news147618795 Scientists have successfully created the first induced pluripotent stem (iPS) cell lines from adult monkey skin cells. The research, published by Cell Press in the December issue of the journal Cell Stem Cell, demonstrates that the method of direct reprogramming is conserved among species and may be useful for creation of clinically valuable primate models for human diseases. http://www.physorg.com/news147532651.html Biology Wed, 03 Dec 2008 13:17:31 EST news147532651 A genetic malfunction that causes DNA instability in people with the blood disorder Fanconi anemia may put them at high risk for squamous cell carcinomas linked to human papillomavirus (HPV), according to a study posted online ahead of print by Oncogene. http://www.physorg.com/news147529555.html Medicine & Health Wed, 03 Dec 2008 12:25:55 EST news147529555 Scientists have new insight into the response of human skin to radiation and what drives the most aggressive and deadly form of skin cancer.
