Living organisms experience various stresses during their lifespans. These stresses include radiation, ultraviolet rays, and chemical substances which directly damage DNA and cause cancer. Organisms are able to speedily repair … Continue Reading Study identifies genes which control cellular senescence.
Leukemia, or blood cancer, involves pathological alterations in the body’s hematopoietic system. In acute myeloid leukemia, it is specifically the bone marrow that is affected. In a healthy body, different … Continue Reading Previously unknown cell-death pathway mapped in leukemia cells.
Being able to detect early on whether a cancer therapy is working proffers obvious benefits for therapy-outcomes whilst influencing the course of treatment and improving the quality of life for … Continue Reading Novel ‘reporter’ nanoparticle reveals cancer treatment effectiveness in real-time.
It is known that cell death is a mechanism used by multicellular organisms to help them survive by removing infected, damaged or unwanted cells. Mitochondria are known as the energy-generating … Continue Reading Researchers identify previously unknown pathway for cell death.
Sudden cardiac death is one of the leading causes of death in Western countries and cardiac arrhythmias have been reported as the cause in many cases. Sudden cardiac arrest occurs … Continue Reading Gene implicated in sudden cardiac death identified by ICD monitoring.
Sudden unexpected death in epilepsy (SUDEP) is becoming increasingly recognized as a very real and devastating problem in which impaired breathing is thought to play a critical role. Researchers believe … Continue Reading Researchers begin to map unexpected death in epilepsy via neurostimulation in human study.
Children who received general anesthesia for surgery before age 4 had diminished language comprehension, lower IQ and decreased gray matter density in posterior regions of their brain, according to a … Continue Reading Researchers link surgical anesthesia in young children to adverse effects on IQ, brain structure.
Adding two non-invasive imaging tests to traditional cardiovascular disease risk factor assessment more precisely predicts a healthy patient’s future risk of heart attack, stroke, or premature death, according to a … Continue Reading New non-invasive bioimaging can detect coronary artery disease long before it strikes.
The average heart beats 35 million times a year, 2.5 billion times over a lifetime. Those beats must be precisely calibrated; even a small divergence from the metronomic rhythm can … Continue Reading Researchers identify protein responsible for keeping the heart beating on time.
Scientists from the CNRS, INSERM and Université de Limoges have demonstrated that the production of type E immunoglobulins (IgE)2 by B lymphocytes induces a loss in their mobility and the … Continue Reading Researchers map programmed cell death in immune cells to prevent allergy.
The power plants that fuel liver cells rapidly splinter when exposed to bile salts that aid digestion, prompting cell death, but blocking this excessive fission appears to protect the liver, … Continue Reading Controlling mitochondria cell-division reduces liver cell death in cholestasis.
Walter and Eliza Hall Institute researchers have for the first time revealed how dying cells are hidden from the immune ‘police’ that patrol the body. The research answers a decades-old … Continue Reading Decades-old mystery about the death of cells uncovered by scientists.
Patients who receive more cells get significant benefits. That’s a key lesson emerging from a clinical trial that was reported at the American Heart Association meeting in Chicago. In this … Continue Reading Dosage determined in landmark human study of stem cell therapy for heart attack.
Groundbreaking research from UT Southwestern Medical Center shows that cholesterol efflux capacity (cholesterol efflux), which measures HDL cholesterol function, appears to be a superior indicator of cardiovascular risk and a … Continue Reading New superior measurement technique of HDL cholesterol function provides cardiovascular risk.
A new study has found that certain prostate cancer medications are linked with an increased risk of dying from heart-related causes in men with congestive heart failure or prior heart … Continue Reading Prostate cancer medications linked to increased heart-related death risk.
