RDAVR system improves survival of patients with severe aortic stenosis

When replacing a defective aortic valve with a new one, restoring function is the first priority. However, variables such as durability, length of surgery, duration of heart stoppage, size of the surgical incision, postoperative pain, and complications are other important considerations.

Unlocking the dark proteome: an interview with Dr Kriwacki

The term dark proteome refers to proteins whose structural features and thus functions are not well understood. Many proteins within the dark proteome do not fold into stable three-dimensional structures. These proteins are called intrinsically disordered proteins (IDPs) and feature highly flexible, disordered confirmations.

Scientists identify role of non-coding elements in shaping human-specific traits

Human-specific variants of four microRNAs may have altered expression levels and gene targets compared to other great apes, according to a study published April 22, 2016 in the open-access journal PLOS ONE by Alicia Gallego from the Institute of Evolutionary Biology, Spain, and colleagues.

Study sheds light on several aspects of Ebola virus flare-ups in Liberia

Ebola virus samples taken from patients in Liberia in June 2015 are strikingly similar in their genetic makeup to other Ebola virus sequences from Western Africa, according to research published online today in the journal Science Advances. The study sheds light on several aspects of the "flare-ups" that have occurred in Liberia since the country was initially declared free of Ebola virus disease.

Differences in timing of stem cells turning into cartilage play major role in shaping the face

Timing is everything when it comes to the development of the vertebrate face. In a new study published in PLoS Genetics, USC Stem Cell researcher Lindsey Barske from the laboratory of Gage Crump and her colleagues identify the roles of key molecular signals that control this critical timing.

Why don’t MS patients always engage with specialists? An interview with Dr Anita Rose

The recent survey you ask about was conducted by the MS Trust in 2012. It revealed that nearly one fifth of respondents had seen neither an MS specialist nurse (MSSN) nor a neurologist in the past year, and so will not have received the comprehensive annual review recommended by the National Institute for Health and Care Excellence (NICE).

Study describes precise mechanisms that enable TB bacteria to persist in the body

Bacteria that cause tuberculosis trick immune cells meant to destroy them into hiding and feeding them instead. This is the result of a study led by researchers from NYU Langone Medical Center and published online April 18 in Nature Immunology.

Researchers reveal how relatively unknown pathogen led to current Zika outbreak

An analysis comparing the individual differences between over 40 strains of Zika virus (30 isolated from humans, 10 from mosquitoes, and 1 from monkeys) has identified significant changes in both amino acid and nucleotide sequences during the past half-century.

FOXO proteins affect dozens of genes common to worms, flies, mice and humans

Whether a creature is a worm, a fly, a mouse, or a human, death inevitably awaits. And not only do these organisms share a common fate, but also, according to a new study, they may share some of the specific mechanisms of mortality. The researchers found that in all four species, there are 46 genes regulated by the same family of "FOXO" proteins known to be central in aging and longevity.

Deadly ‘Crypto’ pathogen lures US researcher to UQ

Cryptococcus is so forsaken by research that it doesn’t even make the neglected diseases list – but the deadly fungal pathogen has lured an American scientist all the way to The University of Queensland.

UC San Diego receives NIH grant to establish interdisciplinary center to combat antibiotic resistance

Researchers at University of California, San Diego School of Medicine have received a five-year, $9.5-million award from the National Institute of Allergy and Infectious Diseases at the National Institutes of Health to establish an interdisciplinary center to define the systems biology of antibiotic resistance. The program will be led by Bernhard Palsson, PhD, Distinguished Professor of Bioengineering and Pediatrics, and Victor Nizet, MD, professor of pediatrics and pharmacy.
