Study sheds light on lung cancers that are undetected by radiograph Posted: 02 Sep 2012 03:49 PM PDT New research has revealed why some lung cancers are undetected by radiograph and helped to identify the type of people who may be at risk of this form of the disease.

Respiratory burden ‘high in aging population’ Posted: 02 Sep 2012 03:49 PM PDT People aged 85 years and over have a high burden of respiratory disease, according to new findings. The research has shed light on the health problems likely to be encountered by the aging population.

Overactive bladder linked to sleep apnea in women Posted: 02 Sep 2012 03:49 PM PDT Sleep apnoea in women has been linked to overactive bladder syndrome in a new study.

Design help for drug cocktails for HIV patients: Mathematical model helps design efficient multi-drug therapies Posted: 02 Sep 2012 11:32 AM PDT For years, doctors treating those with HIV have recognized a relationship between how faithfully patients take the drugs they prescribe, and how likely the virus is to develop drug resistance. New research is helping to explain why those differences exist, and may help doctors quickly and cheaply design new combinations of drugs that are less likely to result in resistance.

Ancient enzymes function like nanopistons to unwind RNA Posted: 02 Sep 2012 11:32 AM PDT DEAD-box proteins, which are ancient enzymes found in all forms of life, function as recycling "nanopistons." They use chemical energy to clamp down and pry open RNA strands, thereby enabling the formation of new structures.

A new light shed on genetic regulation's role in the predisposition to common diseases Posted: 02 Sep 2012 11:32 AM PDT Scientists have discovered several thousands new genetic variants impacting gene expression some of which are responsible for predisposition to common diseases, bringing closer to the biological interpretation of personal genomes.

Anti-HIV drug simulation offers 'realistic' tool to predict drug resistance and viral mutation Posted: 02 Sep 2012 11:32 AM PDT Pooling data from thousands of tests of the antiviral activity of more than 20 commonly used anti-HIV drugs, AIDS experts have developed what they say is the first accurate computer simulation to explain drug effects. Already, the model clarifies how and why some treatment regimens fail in some patients who lack evidence of drug resistance.

Can’t smell anything? Discovery may give you hope Posted: 02 Sep 2012 11:31 AM PDT 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. The achievement in curing congenital anosmia may also aid research on other conditions that also stem from problems with the cilia.

Heavy drinking rewires brain, increasing susceptibility to anxiety problems Posted: 02 Sep 2012 11:31 AM PDT After chronic alcohol exposure, mice are unable to control a learned fear response, shedding light on the link between alcoholism and anxiety problems like post-traumatic stress disorder.

Why children with asthma are more likely to be bullied Posted: 02 Sep 2012 08:35 AM PDT New research has uncovered several factors which could explain why children with asthma are at an increased risk of being bullied.

New technique helps determine degree of muscle wasting in critically ill patients Posted: 02 Sep 2012 08:35 AM PDT Researchers have identified a new technique that can help determine the severity of muscle loss in critically ill patients. The breakthrough could lead to new research to help prevent muscle-wasting and new therapeutic interventions to help treat critically ill patients.

E-cigarettes can damage the lungs, experts warn Posted: 02 Sep 2012 08:35 AM PDT New research has shown that despite electronic cigarettes being marketed as a potentially safer alternative to normal cigarettes, they are still causing harm to the lungs.

Anti-clotting therapy may be used too often following orthopaedic surgery or trauma Posted: 01 Sep 2012 05:51 AM PDT Men and women who undergo joint replacement procedures, as well as those who have significant fractures, tend to be at an increased risk of developing pulmonary emboli (PE), blood clots that travel to the lungs where they may cause serious complications and even death. Patients are often aggressively treated with anticoagulants, or blood thinners, to help prevent the clots from forming, but a new study indicates that some blood clots being identified by today's sensitive testing methods may not require aggressive treatments.

'Missing link' between stem cells and the immune system Posted: 31 Aug 2012 05:33 PM PDT Researchers have discovered a type of cell that is the "missing link" between bone marrow stem cells and all the cells of the human immune system, a finding that will lead to a greater understanding of how a healthy immune system is produced and how disease can lead to poor immune function.
