Researchers find mechanism that controls the growth of B1-cells

Directly after birth, the immune system completes production of a subtype of antibody-producing immune cells, B-1, that are to last for a lifetime. No more B1-cells are formed after that point. However, these cells are self-reactive - they produce not only antibodies against foreign substances, but also against the body's own substances, and it is unclear why the immune system allows for the development of these particular cells.

Pacemaker-like device improves heart function in patients with chemotherapy-induced cardiomyopathy

With the advent of new therapies, cancer patients are surviving longer than ever before -- but the incidence of side-effect chemotherapy-induced cardiomyopathy (CHIC), or weakness of the heart muscle, is increasing.

Bariatric surgery may release toxic compounds from fat into bloodstream, study reveals

Toxic man-made chemicals--such as polychlorinated biphenyls and organochlorine pesticides--that are absorbed into the body and stored in fat may be released into the bloodstream during the rapid fat loss that follows bariatric surgery, according to a study from researchers at the Johns Hopkins Bloomberg School of Public Health.

Substantial changes in blood pressure over long term linked to dementia risk

In a new research study published in the open access journal PLOS Medicine, Albert Hofman and colleagues at Erasmus MC University Medical Center, Rotterdam, the Netherlands and Harvard T.H. Chan School of Public Health, Boston, United States report that people who experienced substantial changes in blood pressure over the long term were at greater risk of dementia than those who did not.

Scientists explore expansion of cytotoxic CD4 T-cells in supercentenarians

Scientists from the RIKEN Center for Integrative Medical Science (IMS) and Keio University School of Medicine in Japan have used single-cell RNA analysis to find that supercentenarians--meaning people over the age of 110--have an excess of a type of immune cell called cytotoxic CD4 T-cells.

Stress affects circadian rhythm, increases metabolic disease risk

Stress is a normal part of life, but too much of everything isn’t healthy. Every day, people from all walks of life experience stress of various degrees. A new study found that when stress has disrupted the circadian rhythm, the body’s internal clock, it can increase the risk of developing metabolic diseases.

Doctors issue stern warning on e-cigarette use as it can damage vital organs

E-cigarette use has increased dramatically over the last decade. With its popularity, the use of e-cigarette spans from adolescents to adults. Now, cardiologists warn against the use of e-cigarettes and how these devices cause damage to vital organs, including the heart, brain, lungs, and blood vessels.
