A team of researchers have developed an open-source, clinically validated template for a 3D printed stethoscope for use in areas of the world with limited access to medical supplies - places where a stethoscope could mean the difference between life and death.

(Boston)--For the first time, researchers have produced a nearly complete three-dimensional structure for the yeast Nuclear Pore Complex (NPC). This discovery represents a major step toward identifying the atomic structure of the NPC, which soon may provide researchers with a better understanding of how the central transport channel functions.

Ever notice how a cut inside the mouth heals much faster than a cut to the skin? Gum tissue repairs itself roughly twice as fast as skin and with reduced scar formation. One reason might be because of the characteristics of gingival mesenchymal stem cells, or GMSCs, which can give rise to a variety of cell types.

HOUSTON, March 14, 2018 - Two University of Houston scientists are reporting that defects in a portion of the brain's hippocampus, called the dentate gyrus, is regulated by the nuclear receptor LXRβ (Liver X receptor Beta). The dentate gyrus, or DG, is responsible for emotion and memory and is known to be involved in autism spectrum disorders (ASD).

Having a larger family is linked to a heightened tooth loss risk for mums, suggest the results of a large European study published online in the Journal of Epidemiology & Community Health.

The popular saying: 'gain a child, lose a tooth' suggests that fertility may be linked to tooth loss, but there are no hard data to back this up.

To try and plug this gap, the researchers drew on data from Wave 5 of the Survey of Health, Ageing, and Retirement in Europe (SHARE).

iQOS, one of the first 'heat not burn' smokeless tobacco products marketed as a safer alternative to conventional cigarettes, may not be as harm free as its manufacturer claims, suggests research published online in the journal Tobacco Control.

An electronic consultation system designed to reduce excessive wait times for appointments with specialists experienced exponential growth during a recent five-year period. The Champlain BASE eConsult service was created to provide primary care clinicians in Ontario, Canada with a range of high quality and timely (up to one week) specialty input. Unlike electronic consultation systems that provide direct links between clinicians, this service enables primary care clinicians to search a directory, select a specialist, and contact her/him through a secure channel.

Shifting physicians' roles from transactional tasks to personalized care would best serve patients, physicians and society. According to a newly-articulated vision of shared care, physicians should reduce their roles in transactional aspects of care, such as gathering and entering data, providing disease-specific patient education, and providing most preventive care. Instead, such duties should be filled by other members of the health care team with complementary skills, leaving physicians to diagnose and help patients meet personal goals and objectives.

The rising prevalence of dental erosion and dentin hypersensitivity has led to the emergence of more and more toothpastes on the market that claim to treat these problems. While no such toothpaste existed 20 years ago, today, many brands with different attributes are being offered.
