Dialog / How AI could help doctors monitor children born with common congenital heart defect
Every echocardiogram is a moving story. For a baby born with a complex heart condition, the gray and black images on the ultrasound screen can influence some of the earliest and most important decisions a medical team makes: ...
Medical Xpress / Skin renews despite 60% to 70% fibroblast depletion in mice, challenging long-held assumption
Human skin is constantly rebuilding itself. Every few weeks, the outermost layers shed and are replaced by new cells pushed up from the base. For decades, scientists believed this renewal depended heavily on fibroblasts, ...
Medical Xpress / Genomic tool highly effective at detecting rare disease diagnoses
A newly developed open-source tool designed for rigorous reanalysis of genomic data is highly effective at detecting new rare disease diagnoses. The tool's ability to frequently and automatically reexamine stored DNA data ...
Medical Xpress / What a 'silenced' chromosome can tell us about autoimmunity
Systemic lupus erythematosus (SLE), the most common form of lupus, is an autoimmune disorder that occurs more frequently in women. Having multiple X chromosomes has been associated with an increased risk of developing lupus; ...
Medical Xpress / Aging reshapes the ovary long before reproductive function ends
Aging affects every organ in the body, yet we still know little about how the ovary changes over time. In a new study published in Nature Aging, Yale researchers created one of the most detailed maps of the aging ovary to ...
Medical Xpress / Early immune clues that determine who develops TB may lead to new ways to intervene earlier and stop the disease
A quarter of the global population is estimated to have been infected with Mycobacterium tuberculosis, yet only 5%–10% of those infected go on to develop active tuberculosis (TB). "The big question has always been what distinguishes ...
Medical Xpress / New technology helps reveal how the heart generates cells with regenerative potential
Two research teams at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) have developed a pioneering technique in Spain to characterize the proteome of individual cardiomyocytes—the cells responsible ...
Medical Xpress / Simple eye scan in preterm infants may help predict brain development
Very preterm infants face up to a 50% higher risk of developmental challenges affecting movement, learning, language and behavior. Today, many of those challenges are not fully recognized until later in infancy or early childhood. ...
Medical Xpress / COVID-19 vaccine study that was blocked from CDC journal is published elsewhere
A study on COVID-19 vaccine effectiveness has finally been published after being blocked from a government health journal.
Medical Xpress / Hidden protein linked to severe COVID-19 and lung disease risk
A genetic difference carried by nearly one in three people may increase the risk of severe COVID-19 and lung fibrosis by disrupting the function of a previously unknown protein, according to a new study published in Nature ...
Medical Xpress / Most patients want cancer diagnoses from doctors, not portals, survey finds
The widespread use of electronic patient portals to provide quick access to test results presents health care professionals with an important challenge: How should new cancer diagnoses be communicated?
Medical Xpress / Mapping the hidden rules of a key immune sensor
The immune system depends on molecular alarms that detect danger inside cells. One of these alarms is STING, short for "stimulator of interferon genes." STING helps cells respond to infections, damaged DNA and cancer. When ...
