(Medical Xpress) -- Imagine being able to create a blood supply for engineered body tissue as a way to test experimental drugs, rather than having to try them out in actual humans. http://medicalxpress.com/news/2011-10-cardiovascular-tiny-functional-blood-vessels.html Medical research Tue, 18 Oct 2011 08:00:54 EST news238143640 People who suffer from acute stroke or Transient Ischaemic Attack (TIA, a mini stroke) could get better treatment in the future thanks to the expansion of a large clinical trial of a new combination of drugs led by researchers at The University of Nottingham. http://medicalxpress.com/news/2011-10-tardis-trial-dimension-treatment.html Cardiology Mon, 17 Oct 2011 09:24:47 EST news238062261 Implanted stents can reopen obstructed arteries, but regrowth of cells into the vessel wall can entail restenosis. Research at LMU now shows that an antimicrobial peptide inhibits restenosis and promotes vascular healing. Thus, coating stents with this peptide could increase their clinical efficacy. http://medicalxpress.com/news/2011-10-effective-lifetime-stents.html Medical research Thu, 06 Oct 2011 11:24:00 EST news237119008 A study supported by the U.S. Department of Health and Human Services could not validate or confirm previous research findings that suggested the presence of one of several viruses in blood samples of people living with chronic fatigue syndrome. The new study also could not find the viruses in blood samples of healthy donors who were previously known to not have the viruses. http://medicalxpress.com/news/2011-09-virus-chronic-fatigue.html Diseases, Conditions, Syndromes Thu, 22 Sep 2011 15:56:16 EST news235925752 Despite improvements in treating heart attack patients needing emergency artery-opening procedures, delays still occur, particularly in transferring patients to hospitals that can perform the procedure, according to a study in Circulation: Journal of the American Heart Association. http://medicalxpress.com/news/2011-09-emergency-treatment-heart.html Cardiology Mon, 19 Sep 2011 16:58:22 EST news235670040 New technology appears to provide faster, more accurate heart scans for both viewing blood vessels in the heart and measuring blood supply to the heart muscle, while exposing patients to less radiation, researchers report in Circulation: Cardiovascular Imaging, a journal of the American Heart Association. http://medicalxpress.com/news/2011-08-heart-scan-diagnosis.html Cardiology Tue, 23 Aug 2011 16:51:08 EST news233337054 Researchers have built the first functional anal sphincters in the laboratory, suggesting a potential future treatment for both fecal and urinary incontinence. Made from muscle and nerve cells, the sphincters developed a blood supply and maintained function when implanted in mice. The results are reported in the medical journal Gastroenterology. http://medicalxpress.com/news/2011-08-human-cells-functional-anal-sphincters.html Medical research Tue, 09 Aug 2011 12:02:23 EST news232107879 A young man who underwent the world's first double leg transplant might be able to walk with the aid of crutches in six or seven months if his rehabilitation goes well, the surgeon who oversaw the operation said Tuesday. http://medicalxpress.com/news/2011-07-spanish-doctor-leg-transplant-patient.html Other Tue, 12 Jul 2011 13:59:44 EST news229697929 Obstructive sleep apnea may cause changes in blood vessel function that reduces blood supply to the heart in people who are otherwise healthy, according to new research reported in Hypertension: Journal of the American Heart Association. http://medicalxpress.com/news/2011-07-links-obstructive-apnea-blood-vessel.html Sleep apnea Mon, 11 Jul 2011 16:00:01 EST news229615150 (Medical Xpress) -- Few treatments exist for patients with advanced primary liver cancer, but University of Florida researchers have found a new way to broaden the range of options and potentially improve health outcomes by combining two treatments. http://medicalxpress.com/news/2011-07-combining-therapies-safe-benefit-patients.html Cancer Wed, 06 Jul 2011 05:31:49 EST news229149022 Scientists from The Scripps Research Institute have identified a surprising new molecular pathway in skin cells that is involved in wound-healing and sensory communication. http://medicalxpress.com/news/2011-06-scientists-molecular-pathway-involved-wound-healing.html Medical research Tue, 28 Jun 2011 17:09:26 EST news228499220 Scientists at the Walter and Eliza Hall Institute have discovered a key molecule needed to kill the blood vessels that supply tumours. http://medicalxpress.com/news/2011-06-strategy-tumor-feeding-blood-vessels.html Medical research Mon, 06 Jun 2011 10:02:20 EST news226573325 (PhysOrg.com) -- Melbourne researchers have developed smart bandages that change colour to reveal the state of the wound beneath.
