http://medicalxpress.com/ en-us Medical Xpress internet news portal provides the latest news on Health and Medicine. Scientists at The Scripps Research Institute (TSRI) have reported successful preclinical tests of a new vaccine against heroin. The vaccine targets heroin and its psychoactive breakdown products in the bloodstream, preventing them from reaching the brain. http://medicalxpress.com/news/2013-05-heroin-vaccine-blocks-relapse-preclinical.html Medical research Mon, 06 May 2013 15:00:22 EST news287057497 A team of scientists anchored at Yale University has demonstrated a new, highly versatile approach for quickly assembling drug-like compounds, establishing a broad new route to drug discovery and medical treatment. They report their results in the journal Science on Feb 8. http://medicalxpress.com/news/2013-02-drug-makers-d-wealth-options.html Medications Thu, 07 Feb 2013 14:00:09 EST news279465907 A system of 'automated design' for new drugs could help develop the complex therapies needed for many medical conditions while also improving drug safety and efficiency, new research from the University of Dundee has shown. http://medicalxpress.com/news/2012-12-automated-drug-discovery.html Medications Wed, 12 Dec 2012 13:00:27 EST news274534514 Scientists at The Scripps Research Institute (TSRI) have performed successful tests of an experimental methamphetamine vaccine on rats. Vaccinated animals that received the drug were largely protected from typical signs of meth intoxication. If the vaccine proves effective in humans too, it could become the first specific treatment for meth addiction, which is estimated to affect 25 million people worldwide. http://medicalxpress.com/news/2012-11-meth-vaccine-results-early.html Psychology & Psychiatry Thu, 01 Nov 2012 09:25:34 EST news270980723 BOSTON--The genomic tumult within tumor cells has provided scientists at Dana-Farber Cancer Institute and the Broad Institute of MIT and Harvard with clues to an entirely new class of genes that may serve as an Achilles' heel for many forms of cancer. http://medicalxpress.com/news/2012-08-cyclops-genes-achilles-heel-tumor.html Genetics Wed, 15 Aug 2012 13:05:18 EST news264254704 (Medical Xpress) -- Researchers at the University of California, Davis, have discovered a class of natural compounds found within the body that may someday lead to pain relief for millions of diabetics and others suffering from chronic pain. http://medicalxpress.com/news/2012-06-discovery-combat-chronic-pain-diabetics.html Diabetes Tue, 26 Jun 2012 08:11:44 EST news259917082 Scientists at The Scripps Research Institute have shown that an injectable solution can protect mice from an otherwise lethal overdose of cocaine. The findings could lead to human clinical trials of a treatment designed to reverse the effects of cocaine in case of emergency. Cocaine is involved in more than 400,000 emergency-room visits and about 5,000 overdose deaths each year in the United States. http://medicalxpress.com/news/2012-04-antidote-cocaine-overdose-lab.html Medications Wed, 18 Apr 2012 12:29:41 EST news253970959 Researchers at the University of Montreal's Sainte-Justine Hospital have identified how neural cells like those in our bodies are able to build up resistance to opioid pain drugs within hours. Humans have known about the usefulness of opioids, which are often harvested from poppy plants, for centuries, but we have very little insight into how they lose their effectiveness in the hours, days and weeks following the first dose. http://medicalxpress.com/news/2012-04-pain-drugs-effective.html Neuroscience Tue, 03 Apr 2012 17:00:08 EST news252688344 A team of Weizmann Institute scientists has turned the tables on an autoimmune disease. In such diseases, including Crohn's and rheumatoid arthritis, the immune system mistakenly attacks the body's tissues. But the scientists managed to trick the immune systems of mice into targeting one of the body's players in autoimmune processes, an enzyme known as MMP9. The results of their research appear today in Nature Medicine. http://medicalxpress.com/news/2011-12-synthetic-molecules-autoimmune-disease-mice.html Immunology Sun, 25 Dec 2011 13:00:01 EST news244013673 Dana-Farber Cancer Institute scientists have successfully disrupted the function of a cancer gene involved in the formation of most human tumors by tampering with the gene's "on" switch and growth signals, rather than targeting the gene itself. The results, achieved in multiple myeloma cells, offer a promising strategy for treating not only myeloma but also many other cancer types driven by the gene MYC, the study authors say. Their findings are being published by the journal Cell on its website Sept. 1 and in its Sept. 16 print edition. http://medicalxpress.com/news/2011-09-approach-scores-success-elusive-cancer.html Cancer Fri, 09 Sep 2011 10:56:16 EST news234784542
