If a patient is no longer able to communicate personally how he or she would like to be treated, doctors and relatives consult an advance directive, if one is available. However, doctors and relatives often interpret patients' written wishes in different ways, as researchers explain in a new report.

Materials science researchers have used computational modelling to shed light on precisely how charged gold nanoparticles influence the structure of DNA and RNA -- which may lead to new techniques for manipulating these genetic materials.

Researchers have produced the first image of an important human protein as it binds with ribonucleic acid (RNA), a discovery that could offer clues to how some viruses, including HIV, control expression of their genetic material. That information could lead to new strategies to block viruses from…

A new study strengthens growing evidence that Mycoplasma genitalium (MG) is a sexually transmitted infection (STI). Prevalence was much higher in those who had reported more than four sexual partners in the past year -- 5.2% in men and 3.1% in women. Absence of the infection in over 200 16-17 year…

New work describes the steps and processes governing myoblast fusion with muscle fibres during the formation of flight muscles in Drosophila. The developmental program of these flight muscles and their muscle fibre organization resemble key aspects of vertebrate skeletal myogenesis. Therefore, this…

A study of patients who underwent an emergency general surgery procedure found that hospital readmission was common and varied widely depending on patient factors and diagnosis, according to a study.

Patients who develop ovarian cancer appear to have better outcomes if they have a history of oral contraceptive use, according to a study.

An interdisciplinary team of biologists and medical researchers has created a new platform, which they call GEneSTATION specifically designed to leverage the growing knowledge of human genomics and evolution to advance scientific understanding of human pregnancy and translate it into new treatments…

New research is shedding important light on the DNA repair process and a protein newly discovered to have an essential role in preventing errors and mutations from occurring.

Organized extracurricular sport activities for children help them develop and improve cognitive skills, such as greater concentration capacity, that can in term greatly help them in the classroom, suggests a researcher.

A smartphone-based device known as HeartBuds performed just as well as traditional stethoscopes and better than a disposable model in identifying heart murmurs and other vital sounds during patient exams.

A new molecular biology tool derived from a bacterial defense system has been used for the first time to demonstrate a novel way to protect plants against viral pathogens.

A breakthrough has been achieved with the results of the world-first clinical trial with actual patients of a new drug to treat particular blood cancers. This clinical trial, a first-in-human study, looked at the efficacy of a new inhibitor, ONO/GS-4059, in the treatment of Chronic Lymphocytic…

When a person receives a cancer treatment through radiation, he or she is exposed to ionizing radiation and to avoid that energy to damage healthy tissue. A new study looked at the properties of various materials called dosimeters that measure radiation doses.

Results from a phase I clinical trial showed that the first-in-class, investigational, anticancer therapeutic pevonedistat was safe, tolerable, and had some anticancer activity in heavily pretreated patients with relapsed/refractory lymphoma.

Medical marijuana needs to be studied like any other drug. No one is opposed to the active ingredients in it, but we need to have some data. That is what we would expect from any other drug, an expert says.

Why a dietary treatment works for some but not others seems to depend on interactions between the gut microbiota and the diet. A new study shows that people with better control of blood sugar after eating barley kernel bread also have a different balance of microbes in the gut.

Researchers have discovered that a mutation in a coronavirus protein slows the spread of the virus in the central nervous system and reduces its neurovirulence. It is the first time that this phenomenon has been observed in the coronavirus family, which is responsible for one-third of common colds…

A new "progenitor cell" capable of unlimited expansion and differentiation into mature kidney cells, but without the risk of forming tumors, has been described by researchers in a new article.

Researchers have found that produce that contained bacteria would contaminate other produce items through the continued use of knives or graters -- the bacteria would latch on to the utensils commonly found in consumers' homes and spread. Unfortunately, many consumers are unaware utensils and other…

Treatment with antiangiogenesis drugs may improve the effectiveness of radiation treatment of nervous system tumors that interfere with the hearing of patients with the genetic disorder neurofibromatosis 2, investigators report.

With childhood obesity rates on the rise, a team of based researchers embarked on a study to show how authoritarian parenting and household income combine to affect kid's obesity risk.

Chronic exposure to arsenic can lead to stem cell dysfunction that impairs muscle healing and regeneration. More than 140 million people worldwide and 4 million Americans chronically ingest arsenic in their drinking water. The 21st most abundant metal in Earth's crust, arsenic is naturally present…

A state-of-the-art open-source tool captures fine details of locomotion and offers new insights onto the neural basis of balance and coordination, report developers. Using LocoMouse, the researchers analyzed locomotion in mice with cerebellar degeneration, and were surprised to discover that many…

Use of low energy sweeteners (LES) in place of sugar, in children and adults, leads to reduced calorie intake and body weight - and possibly also when comparing LES beverages to water -- according to a new review.
