Scientists study how viral evolution occurs

Viruses evolve quickly. A small tweak to the genetic makeup of a mostly mild strain of influenza can give rise to the next pandemic. An equally small change to the same strain in a different setting can fade it into obscurity.

Chloride switch controls critical step in basement membrane formation

Chloride plays a key role in the formation of the basement membrane, a suprastructure on the outside of cells that undergirds and guides the function of most of the tissues of the body.

Novel strategy to predict antigenic evolution of circulating influenza viruses

During the 2014-15 flu season, the poor match between the virus used to make the world's vaccine stocks and the circulating seasonal virus yielded a vaccine that was less than 20 percent effective.

ULK1, ULK2 enzymes play key role in maintaining cellular homeostasis

Researchers at St. Jude Children's Research Hospital have uncovered how two enzymes, ULK1 and ULK2, which are best known for their role in the degradation and recycling of proteins, control the trafficking of specific proteins.

UCL researchers identify four genes that drive shape of human noses

Genes that drive the shape of human noses have been identified by a UCL-led study. The four genes mainly affect the width and 'pointiness' of noses which vary greatly between different populations. The new information adds to our understanding of how the human face evolved and may help contribute to forensic DNA technologies that build visual profiles based on an individual's genetic makeup.

Landmark study characterizes evolution of symptoms, signs of acute HIV infection

Acute HIV infection (AHI) contributes significantly to HIV transmission and may be important for intervention strategies seeking to reduce incidence and achieve a functional cure.

First-ever clinical trial of bioabsorbable cardiovascular device in children shows promise

Current cardiovascular valve or blood vessel implants are generally associated with a number of complications, have limited efficacy over time, and may necessitate repeated interventions over a patient's lifetime, especially when implanted in a young child.

Ascensia Diabetes Care receives CE Mark approval for new CONTOUR™ PLUS ONE and CONTOUR™ NEXT ONE blood glucose monitoring systems

Ascensia Diabetes Care announced that it has received CE Mark (Conformité Européenne) for the new CONTOUR™ NEXT ONE and CONTOUR™ PLUS ONE blood glucose monitoring systems, the next exciting development in the evolution of self-monitoring of blood glucose for people with diabetes.

Researchers identify risk factors for unplanned readmissions following esophageal resection

Esophagectomy is a major surgical procedure associated with significant complications with up to 1 in 5 patients readmitted following hospital discharge. These unplanned readmissions are an important problem as they negatively impact patient care and, in the future, may have implications for reimbursement through the Hospital Readmissions Reduction program.

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.

Researchers identify out of control immune system linked to neurodegenerative diseases

AN out of control immune system has been identified as a possible cause of neurodegenerative diseases such as Alzheimer’s.

Mice study reveals signs of stress-related early maturation in vital brain region

Intuition is all one needs to understand that stress in early childhood can create lifelong psychological troubles, but scientists have only begun to explain how those emerge in the brain.

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.

Novel iPad simulation app can instruct future nurses in monitoring babies and mothers during labor

Sheila Taylor leaned in to see the baby's heartbeat rhythm. She watched as the baby's heartbeat line fell without a corresponding spike showing the mother's uterus contracting down on it.

Researchers monitor ICP and PRx to characterize temporal evolution in severe TBI patients

Winner of the Best International Abstract Award, Hadie Adams, presented his research, Characterizing the Temporal Evolution of ICP and Cerebrovascular Reactivity after Severe Traumatic Brain Injury, during the 2016 American Association of Neurological Surgeons Annual Scientific Meeting.

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.
