Researchers from the University of Virginia (UVA) School of Medicine have discovered a gene in the Y (the sex chromosomes only present in males) chromosome that contributes to the increased incidence of heart failure among men, possibly opening new avenues to treatments. Their findings have been published in Nature Cardiovascular Research. People normally have one …
Individuals with obesity are more likely to have monoclonal gammopathy of undetermined significance (MGUS), a benign blood condition that often precedes multiple myeloma, according to new research published in Blood Advances. Multiple myeloma is a blood cancer of the plasma cells, a type of white blood cells that produce antibodies to fight infection. MGUS, characterized …
Taking a bite of an apple is considered a healthy choice. But have you ever thought about putting in earplugs before your favorite band takes the stage? Just like your future body will thank you for the apple, your future ears (specifically your cochlear hair cells) will thank you for protecting them. The most common …
A protein that prepares DNA for replication also prevents the replication process from running out of control, according to a new study by Weill Cornell Medicine researchers. The work, published on Jan. 5 in Molecular Cell, solves a mystery that has long puzzled biologists. The cells of humans and all other higher organisms use a …
Researchers at UC San Francisco (UCSF) have engineered molecules that act like “cellular glue,” allowing them to direct in precise fashion how cells bond with each other. The discovery represents a major step toward building tissues and organs, a long-sought goal of regenerative medicine. Adhesive molecules are found naturally throughout the body, holding its tens …
During adolescence, sex hormones drive significant physiologic changes. One of the most universal, and sometimes distressing, experiences during adolescence is the development of acne — a skin condition that results from the plugging of hair follicles with oil and dead skin cells. For some individuals whose acne is resistant to topical therapies, systemic antibiotics are …
Scientists at Nanyang Technological University, Singapore (NTU Singapore) have found that a stress response in cells, when ‘switched on’ at a post-reproductive age, could be the key to slowing down aging and promoting longevity. In lab experiments on a type of roundworm that shares similarities with humans, the NTU Singapore team found that switching on …
Researchers identified a group of neurons in mice that trigger sickness symptoms, such as fever and loss of appetite, in response to infections. The findings could lead to better ways to reverse these symptoms When you get an infection, many changes happen in your body. Aside from the activity of the immune system, physiological and …
Researchers at the University of Houston are reporting a first-of-its-kind technology that not only repairs heart muscle cells in mice but also regenerates them following a heart attack, or myocardial infarction as its medically known. Published in the Journal of Cardiovascular Aging, the groundbreaking finding has the potential to become a powerful clinical strategy for …
Our brains rarely record single memories. Instead, they store memories in groups so that the recollection of one significant memory triggers the recall of others that are connected chronologically. As we age, however, our brains gradually lose this ability to link related memories. Now, according to the press release, UCLA researchers have discovered a key …
