Poor sleep quality appears to be an important risk factor for atrial fibrillation, report scientists in the first study of its kind to demonstrate a relationship between poor sleep quality independent of sleep apnea and a higher risk of atrial fibrillation (AF). Their findings are published in HeartRhythm. AF is an irregular, rapid heart rate

The overproduction of the BCL-2 protein is due to a defect in the ribosome, the protein factory of the cell. This defect is found in 10% of the pediatric patients with T-cell leukemia. Ribosome defects and cancer “In the past couple of years, it has become clear that ribosome defects play a role in different

How are chromosomes arranged in the cell nucleus? Is it possible that they communicate with one another by “touching” each other? To answer this question and to shed more light on the fundamental properties of the communication between different chromosomes, Philipp Maass from Friedrich Luft’s lab at the Max Delbrück Center for Molecular Medicine in

Setbacks are to be expected when pursuing a goal, whether you are trying to lose weight or save money. The challenge is getting back on track and not giving up after a difficulty or crisis, says a marketing professor in Iowa State University’s Ivy College of Business. José Rosa, John and Deborah Ganoe Faculty Fellow,

A new study by Professors Martti Juhola and Katriina Aalto-Setälä of the University of Tampere in Finland demonstrates that with the use of artificial intelligence and machine learning, it is possible not only to accurately sort sick cardiac cell cultures from healthy ones, but also to differentiate between genetic cardiac diseases. iPSC-derived cardiomyocytes can be

When Navy SEALs carry out dives in Arctic waters, or when rescue teams are diving under ice-covered rivers or ponds, the survival time even in the best wetsuits is very limited — as little as tens of minutes, and the experience can be extremely painful at best. Finding ways of extending that survival time without

Pregnancy loss and the death of a newborn baby are devastating events, and as of today around 25% of these perinatal deaths are unexplained despite autopsy. Discovering the cause of such a loss is of great importance for the bereaved parents, both in providing an explanation and in helping them to understand the likelihood of

We’ve all experienced going to bed tired and waking up refreshed, yet how that happens at the molecular level remains a mystery. An international study published today in Nature sheds new light on the biochemistry of sleep need in the brain. According to the American Sleep Association, 50 million to 70 million U.S. adults have

Electronic textiles could allow a person to control household appliances or computers from a distance simply by touching a wristband or other item of clothing — something that could be particularly helpful for those with limited mobility. Now researchers, reporting in ACS Nano, have developed a new type of e-textile that is self-powered, highly sensitive

Purdue University researchers think the gap between a psychologists’ diagnosis and a patient’s self-evaluation might not be as extreme as previously perceived when both are using the same evaluation tools. The research findings are published in the Journal of Consulting and Clinical Psychology. They lessen concerns that people lack awareness of their own personality pathology.

An international team of researchers including USC scientists has found scores of new genetic markers in DNA code that increase prostate cancer risk — powerful knowledge likely to prove useful to detect and prevent the disease. Focusing on DNA of more than 140,000 men worldwide, researchers were able to identify 63 new genetic markers associated

A team of researchers at VIB and KU Leuven has uncovered why people with a hereditary form of Parkinson’s disease suffer from sleep disturbances. The molecular mechanisms uncovered in fruit flies and human stem cells also point to candidate targets for the development of new treatments. Sleep and Parkinson’s Parkinson’s disease affects 5 million people

Tonsil and adenoid removal associated with long-term risks of respiratory, allergic and infectious diseases Removing tonsils and adenoids in childhood increases the long-term risk of respiratory, allergic and infectious diseases, according to researchers who have examined — for the first time — the long-term effects of the operations. The researchers suggest renewed evaluation of alternatives

Scientists have zeroed in on a culprit that spurs damaging inflammation in the heart following a heart attack. The guilty party is a type of immune cell that tries to heal the injured heart but instead triggers inflammation that leads to even more damage. Further, the researchers have found that an already approved drug effectively

A collaborative research team is on a quest to collapse a tiny pocket between cardiac cells that can cause big problems. Called the perinexus, the structure spans only tenths of a millimeter — all the space it needs to disrupt a person’s heartbeat. The researchers were the first to identify the perinexus in humans. They

Managing type 1diabetes during the first two decades of life is challenging. Insulin requirements change along with the stages of life — childhood, puberty, young adulthood, and beyond. But a 20-year longitudinal study conducted by researchers from Joslin Diabetes Center and Harvard Medical School identifies clear predictors of rising A1C levels in young persons, as

Physicians may want to dig a little deeper into their closets, or grab their white coats on the way out of the operating room, if they want patients to view them favorably, according to the largest-ever study of patient preferences for doctors’ attire. In fact, what medical doctors wear may matter more than most doctors

One of the main risk factors for non-melanoma skin cancer (NMSC), the most common cancer worldwide, is solar ultraviolet radiation. A new Journal of the European Academy of Dermatology and Venereology study has found that different outdoor professions carry different risks for NMSC. In the study of 563 participants (47% women) consisting of 348 outdoor

A tailored lighting intervention in nursing homes can positively impact sleep, mood and behavior for patients with Alzheimer’s disease, according to preliminary findings from a new study. People with Alzheimer’s disease and related dementias may experience sleep problems, wandering, and associated daytime irritability. This study tested whether a tailored daytime lighting intervention could improve sleep

Preliminary results from a new study show that excess heart age (EHA) appeared to be lowest among adults who reported sleeping seven hours per 24-hour period. Results show that mean adjusted EHA was lowest among adults who reported sleeping seven hours per 24-hour period. Sleeping times less than or greater than seven hours were associated
