The hunt for an HIV vaccine has gobbled up $8 billion in the past decade, and the failure of the most recent efficacy trial has delivered yet another setback to 26 years of efforts. http://medicalxpress.com/news/2013-05-gap-hiv-vaccine-efforts-latest.html HIV & AIDS Sun, 19 May 2013 09:20:01 EST news288173183 Researchers at Weill Cornell Medical College have successfully tested their novel anti-cocaine vaccine in primates, bringing them closer to launching human clinical trials. Their study, published online by the journal Neuropsychopharmacology, used a radiological technique to demonstrate that the anti-cocaine vaccine prevented the drug from reaching the brain and producing a dopamine-induced high. http://medicalxpress.com/news/2013-05-cocaine-vaccine-key-hurdle.html Psychology & Psychiatry Fri, 10 May 2013 14:08:40 EST news287413696 A protein known to be a key player in the development of Parkinson's disease is able to enter and harm cells in the same way that viruses do, according to a Loyola University Chicago Stritch School of Medicine study. http://medicalxpress.com/news/2013-04-parkinson-disease-protein-virus.html Parkinson's & Movement disorders Thu, 25 Apr 2013 17:00:01 EST news286122034 (HealthDay)—Some people seem to catch a cold every few weeks while others appear immune.

The study indicates that the virus HCoV-EMC can penetrate the lining of the passageways in the lung and evade the innate immune system as easily as a cold virus can, signs that HCoV-EMC is well-equipped for infecting human cells. The study also reveals that the virus is susceptible to treatment with interferons, components of the immune system that have been used successfully to treat other viral diseases, opening a possible mode of treatment in the event of a large-scale outbreak. http://medicalxpress.com/news/2013-02-coronavirus-well-adapted-humans-susceptible-immunotherapy.html Diseases, Conditions, Syndromes Tue, 19 Feb 2013 04:20:01 EST news280468360 University of New South Wales researchers have developed a compound that has had a surprise result: being effective in the prevention of asthma. http://medicalxpress.com/news/2013-01-reversing-symptoms-asthma.html Inflammatory disorders Tue, 22 Jan 2013 06:28:47 EST news278058507 Cold viruses generally get a bad rap—which they've certainly earned—but new findings by a team of scientists at the Salk Institute for Biological Studies suggest that these viruses might also be a valuable ally in the fight against cancer. http://medicalxpress.com/news/2012-10-cold-viruses-cancer-therapies.html Cancer Tue, 16 Oct 2012 17:27:26 EST news269627232 (Medical Xpress)—A team of scientists from Johns Hopkins and other institutions report that restoring tiny, hair-like structures to defective cells in the olfactory system of mice is enough to restore a lost sense of smell. The results of the experiments were published online this week in Nature Medicine, and are believed to represent the first successful application of gene therapy to restore this function in live mammals. http://medicalxpress.com/news/2012-09-gene-therapy-mice.html Medical research Tue, 11 Sep 2012 07:50:10 EST news266568598 Scientists have restored the sense of smell in mice through gene therapy for the first time—a hopeful sign for people who can't smell anything from birth or lose it due to disease. http://medicalxpress.com/news/2012-09-gene-therapy-aid-diseases-cilia.html Medical research Sun, 02 Sep 2012 13:00:01 EST news265786223 There is no question that being a parent is, at times, challenging both physically and mentally.

Rhinovirus, the virus responsible for the common cold was found at some point during an 8-week study period in an estimated 60% of university students that were asymptomatic. Researchers from Canada report their findings at the 2012 General Meeting of the American Society for Microbiology. http://medicalxpress.com/news/2012-06-asymptomatic-rhinovirus-infection-outnumbers-symptomatic.html Diseases, Conditions, Syndromes Tue, 19 Jun 2012 16:00:01 EST news259340305 A long-term follow-up analysis of participants in the Step Study, an international HIV-vaccine trial, has confirmed that certain subgroups of male study participants were at higher risk of becoming infected after receiving the experimental vaccine compared to those who received a placebo. The vaccine used in the study did not contain the HIV virus, but it did contain HIV genes which were delivered to cells using a vector that employed a type of cold virus known as adenovirus serotype 5 (Ad5). http://medicalxpress.com/news/2012-05-early-elevated-hiv-infection.html HIV & AIDS Mon, 07 May 2012 11:35:16 EST news255609306 (Medical Xpress) -- Unfortunately, kids get sick. Fighting a virus or common cold is good for a child’s immune system and can help build antibodies that protect them from dangerous illnesses. Still, there are times when that tummy ache or cough may require medical attention. http://medicalxpress.com/news/2012-03-doctor-child-symptoms.html Health Thu, 01 Mar 2012 08:10:01 EST news249809494 People often talk about "boosting" their immunity to prevent and fight colds.
