Using solid-state nuclear magnetic resonance (NMR) spectroscopy, researchers at Luleå University of Technology in collaboration with Warwick University in the UK for the first time in the world managed to analyse hydrogen bonds in tiny fibrils of Amyloid-beta peptide , which probably causes Alzheimer's disease. Thanks to these new results, there is a successful method avaliable – for analysis of structure of Amyloid-beta peptides in their most toxic form, that is, when they are most dangerous for the brain neurons. http://medicalxpress.com/news/2012-11-amyloid-beta-peptide-alzheimer.html Alzheimer's disease & dementia Mon, 05 Nov 2012 08:15:14 EST news271325694 Bisphenol A or BPA is a synthetic chemical widely used in the making of plastic products ranging from bottles and food can linings to toys and water supply lines. When these plastics degrade, BPA is released into the environment and routinely ingested. http://medicalxpress.com/news/2012-10-bpa-real-threat-metabolized.html Health Thu, 04 Oct 2012 17:00:02 EST news268587274 The molecular structure of a protein involved in Alzheimer's disease – and the surprising discovery that it binds cholesterol – could lead to new therapeutics for the disease, Vanderbilt University investigators report in the June 1 issue of the journal Science. http://medicalxpress.com/news/2012-05-alzheimer-protein-treatment.html Alzheimer's disease & dementia Thu, 31 May 2012 14:00:10 EST news257689478 A group of researchers from the IMIM (Hospital del Mar Research Institute) and from the INAD (Hospital del Mar Neuropsychiatry and Addictions Institute) has participated in an international study aiming to give a general overview at a chemical, pharmacological and behavioural level of a recently appeared new chemical compound, according to the Recreational Drugs European Network, as a new abused drug: methoxetamine (MXE). http://medicalxpress.com/news/2012-05-internet-drugs-health.html Health Tue, 08 May 2012 09:59:31 EST news255689950 A team of scientists from the Scripps Research Institute, collaborating with members of the drug discovery company Receptos, has created the first high-resolution virtual image of cellular structures called S1P1 receptors, which are critical in controlling the onset and progression of multiple sclerosis and other diseases. This new molecular map is already pointing researchers toward promising new paths for drug discovery and aiding them in better understanding how certain existing drugs work. http://medicalxpress.com/news/2012-02-scientists-molecular-treatment-multiple-sclerosis.html Medical research Thu, 16 Feb 2012 14:00:15 EST news248612651 (Medical Xpress) -- An international team of scientists, led by the University of Sydney, has found the molecular structure in the body which functions as our 'shock absorber'. http://medicalxpress.com/news/2012-02-human-absorbers.html Medical research Tue, 14 Feb 2012 06:20:02 EST news248420649 A malignancy-risk gene signature developed for breast cancer has been found to have predictive and prognostic value for patients with early stage non-small cell lung cancer. The advancement was made by researchers at Moffitt Cancer Center in Tampa, Fla., who published their study results in a recent issue of the Journal of the National Cancer Institute. http://medicalxpress.com/news/2012-01-malignancy-risk-gene-signature-early-stage-non-small.html Cancer Fri, 06 Jan 2012 10:48:12 EST news245069277 University of Tennessee researcher uses computer simulation to pinpoint changes in molecular structure that leads directly to disease. http://medicalxpress.com/news/2011-06-scientists-uncover-trigger-fatal-neurodegenerative.html Medical research Wed, 22 Jun 2011 08:23:36 EST news227949797
