Both enteral (tube feeding) and parenteral (intravenous feeding) nutrition have been commonly practiced in intensive care units for four decades. However, there is little independent evidence to suggest that they are efficacious. Now a new study from researchers in the University of Illinois and Rush University Medical Center, both in Chicago, suggests that it might even bring inherent dangers, with increased mortality risk. The study is published on 10th April 2014 in the Journal of Parenteral and Enteral Nutrition.

The cancer protein KRas is a factor in the development of several types of cancer. Mutated KRas, for example, can be found in a large number of all tumour cells in patients with pancreatic cancer. It sits on the inner leaflet of the cell membrane and relays signals into the cell’s interior. Scientists at the Max Planck Institute of Molecular Physiology in Dortmund have now discovered why KRas is almost exclusively found at the cell membrane when observed under the microscope.

A major problem in eradicating HIV using combination antiretroviral therapy (cART) lies with the latent HIV pool that ‘hides’ in CD4 T cells, ready to replicate as soon as cART is interrupted. A new study led by researchers in  Gilead Sciences, Foster City, USA shows that the potent histone deacetylase inhibitor Romidepsin is effective in a ‘kick and kill’ approach to HIV.  This involves reactivating latent HIV to make it susceptible to cART. The study is published in PLoS Pathogens on April 10th 2014.

The H5N1 bird flu virus has infected and killed hundreds of people, despite the fact that, at the moment, the virus can't spread easily between people. The death toll could become much worse if the virus became airborne. A study published by Cell Press April 10th in the journal Cell has revealed a minimal set of mutations allowing H5N1 to be transmitted through the air from one ferret to another. The findings will be invaluable for future surveillance programs and may provide early warning signals of the emergence of potential pandemic strains.

A new study shows that South American oilbird is the most genetically distinct bird and has not shared its genes with any other bird on the planet, in the last 80 million years. The cuckoo roller of Madagascar also remained evolutionarily distinct for a long time, more than 65 million years.

Children who have suffered a head injury, for example in a car crash, experience unexpected long-term problems with relationships and social interactions although they appear to be completely recovered. This is due to lasting effects on the right frontal pole area of the brain that could be addressed with therapy to improve working memory. These are the main findings of a study from researchers in Brigham Young University published on 10th April in the Journal of Head Trauma Rehabilitation.
