In Austria approximately 16,000 people fall ill with borreliosis annually following a tick bite. Roughly every fifth tick in Austria carries the pathogen. Borreliosis can be treated effectively with antibiotics, however a prophylactic vaccination is not available. In a current multicentre study, in which the MedUni Vienna participated, the reliable effectiveness of a possible vaccine against borreliosis has now been proved. http://medicalxpress.com/news/2013-05-effective-vaccination-borreliosis.html Diseases, Conditions, Syndromes Tue, 14 May 2013 08:53:29 EST news287740400 A change to the so-called TERT gene considerably increases the risk of breast and ovarian cancer. This is the result of a current, multicenter study in which the University Department of Gynaecology and the Comprehensive Cancer Center Vienna (CCC), an establishment belonging to the MedUni Vienna and Vienna General Hospital, were taking part. http://medicalxpress.com/news/2013-05-gene-mutation-breast-ovarian-cancer.html Cancer Fri, 10 May 2013 09:00:02 EST news287394495 Cholesterol plays a key role in regulating proteins involved in cell signaling and may be important to many other cell processes, an international team of researchers has found. http://medicalxpress.com/news/2012-12-cholesterol-key-proteins-cell.html Medical research Wed, 19 Dec 2012 12:04:56 EST news275141089 (HealthDay)—Being both neurotic and conscientious may be good for your health. http://medicalxpress.com/news/2012-11-healthy-neurotic-conscientious.html Psychology & Psychiatry Sat, 24 Nov 2012 17:00:31 EST news272998824 (Medical Xpress)—A new clinical research study at Roswell Park Cancer Institute (RPCI) will test a first-of-its-kind cancer "vaccine" that may prove effective against many forms of solid-tumor cancers. The vaccine, to be investigated in a trial involving patients with brain cancer, generates an immune response that appears to put the target molecule, the cancer survival protein survivin, into a bind it can't escape. http://medicalxpress.com/news/2012-09-brain-cancer-vaccine-peptide-survival.html Cancer Fri, 28 Sep 2012 09:39:25 EST news268043955 Details of a treatment that could help asthmatics fight infections that trigger 80% of asthma attacks, developed by University of Southampton spin-out company Synairgen, will be presented to European respiratory experts on Sunday 2 September. http://medicalxpress.com/news/2012-08-breathable-treatment-asthma.html Immunology Fri, 31 Aug 2012 11:07:05 EST news265630016 Johns Hopkins researchers have discovered that a single protein molecule may hold the key to turning cardiac stem cells into blood vessels or muscle tissue, a finding that may lead to better ways to treat heart attack patients. http://medicalxpress.com/news/2012-06-master-molecule-stem-cell-treatment.html Cardiology Wed, 20 Jun 2012 15:35:50 EST news259424199 Researchers at the University of Illinois at Chicago College of Medicine have found that a molecule found at elevated levels in cancer cells seems to protect them from the "cell-suicide" that is usually triggered by chemotherapy or radiation. http://medicalxpress.com/news/2012-03-molecule-role-cancer-combination-therapy.html Cancer Thu, 01 Mar 2012 11:29:41 EST news249823774 In a study conducted by researchers at Moffitt Cancer Center and colleagues from 11 other institutions in the Unites States and the United Kingdom, genes that are known to be involved in inflammation were found to be related to risk of ovarian cancer. http://medicalxpress.com/news/2012-02-ovarian-cancer-inherited-inflammation-genes.html Cancer Tue, 07 Feb 2012 12:47:44 EST news247841232 Researchers at the Medical College of Wisconsin have shown that a protein can inhibit metastasis of colon and melanoma cancers.

As tumors can initially grow unchecked in the abdomen without causing any major symptoms, patients are usually diagnosed at an advanced stage and have to undergo surgery plus chemotherapy. During the operation, surgeons attempt to remove all tumor deposits as this leads to improved patient prognosis. To do this, however, they primarily have to rely on visual inspection and palpation - an enormous challenge especially in the case of small tumor nests or remaining tumor borders after the primary tumor excision. http://medicalxpress.com/news/2011-09-imaging-technique-visualizes-cancer-surgery.html Cancer Mon, 19 Sep 2011 10:23:08 EST news235646542 A protein molecule that 'glues' cells together and so has a key role in cancer is also responsible for many other important functions of cells, a new study has found. http://medicalxpress.com/news/2011-07-stem-cell-reveals-complexity-molecule.html Cancer Thu, 14 Jul 2011 17:00:06 EST news229875322
