Study explains effects of aging on endothelial health and vascular regenerative capacity

The endothelium plays an important role in cardiovascular regulation, from blood flow to platelet aggregation, immune cell infiltration and demargination.

Formula of 80 and precautions can help prevent heart attack during festive season

According to a new study, Christmas Eve is one of the most dangerous times of the year for the heart. It has indicated that a person’s risk for heart attack reaches its peak around late night a day before Christmas.

Gently stroking babies could provide effective pain relief before medical procedures

Researchers found that gently stroking a baby seems to reduce activity in the infant brain associated with painful experiences. Their results, appearing December 17 in the journal Current Biology, suggest that lightly brushing an infant at a certain speed--of approximately 3 centimeters per second--could provide effective pain relief before clinically necessary medical procedures.

Scientists suggest need for new approach to confront side effects of common anti-cancer therapy

Results of a new study by neuroscientists at the University of Massachusetts Amherst and the University of Toronto suggest that a new treatment approach is needed - and how this may be possible - to address adverse effects of aromatase inhibitors, drugs commonly prescribed to both men and women to prevent recurrence of estrogen-positive breast cancer.

Study finds risk factors linked to REM sleep behavior disorder

Taking antidepressants for depression, having post-traumatic stress disorder or anxiety diagnosed by a doctor are risk factors for a disruptive and sometimes violent sleep disorder called rapid eye movement (REM) sleep behavior disorder, according to a study published in the December 26, 2018, online issue of Neurology, the medical journal of the American Academy of Neurology.

New method of cancer stem cells activation to destroy tumors

This risky method of anti-cancer therapy was suggested by scientists of Far Eastern Federal University (FEFU). Their review of mechanisms for molecular activation of stem cells of gliomas (most widely-spread brain tumors) was approved for publishing in the Frontiers in Cellular Neuroscience journal.

New mechanism may explain neurons shrinking in Huntington's disease

A hallmark of neurodegenerative diseases like Huntington's is the progressive death of nerve cells in the brain. The cells don't die quickly, though. They first start to disconnect from each other because their neurites -- long finger-like extensions that make connections all through the brain -- become smaller.

Surfer's ear reveals important clues to lives of ancient pearl divers in Panama

While examining a skull from an ancient burial ground in a pre-Columbian village in Panama, Nicole Smith-Guzmán, bioarchaeologist at the Smithsonian Tropical Research Institute (STRI), was surprised to discover an example of surfers' ear: a small, bony bump in the ear canal common among surfers, kayakers and free divers in cold climates.

The impact of maternal diabetes on fetal heart development

Congenital heart disease is the most common birth defect. And even with remarkable advances in care, it remains the leading cause of non-infectious death in infants.

Simple protocol rescues stressed liver cells

Isolated human hepatocytes are essential tools in preclinical and clinical liver research, but cell quality is highly variable. Now, researchers from Uppsala University have devised a simple protocol that improves hepatocyte quality and enables cells from a wider quality spectrum to be used in standard and advanced cell culture. The findings are published in Archives of Toxicology.

Study lays foundation for addressing unresolved questions in human aging

Doctors have long observed that biological age and chronological age are not always one and the same. A 55-year-old may exhibit many signs of old age and have numerous age-related diseases, whereas an 80-year-old may be healthy and robust.

Scientists discover new biomarkers for early detection of cystic fibrosis

Scientists at McMaster University have discovered several new biomarkers from a single drop of blood that could allow earlier and more definitive detection of cystic fibrosis, a genetic disease which strikes both children and adults, causing chronic problems with the digestive system and the lungs.

Childbirth delivery mode linked with woman’s risk of developing pelvic floor disorders

Research completed at Johns Hopkins and the Greater Baltimore Medical Center has demonstrated that vaginal childbirth substantially increases the probability a woman will develop a pelvic floor disorder later in life.

Stress related pathway instrumental in controlling function of immune cells

The immune system is composed of a wide range of different immune cells each with dedicated functions. Natural killer T cells form a specialized immune cell that protects against a variety of diseases such as cancer, autoimmunity, metabolic disease or certain infections such as Lyme disease.

Osteoporosis is not only a women's disease

Osteoporosis, a bone disease that can result in painful fractures - typically in the back, hip or wrist - is often thought of as a woman's disease. But men get it too, just usually later in life than women.

Cognition not affected by major heart procedure

Patients who undergo heart surgery do not experience major memory changes—either better or worse—when compared with those who have a much less invasive, catheter-based procedure, according to a study published online today in The Annals of Thoracic Surgery.

Surgeons make more mistakes in the operating room during stressful moments, shows study

A new study reveals that during stressful moments in the operating room, surgeons make up to 66 percent more mistakes on patients.

Green leafy vegetables may reduce risk of developing liver steatosis

A larger portion of green leafy vegetables in the diet may reduce the risk of developing liver steatosis, or fatty liver. In a study published in PNAS researchers from Karolinska Institutet in Sweden show how a larger intake of inorganic nitrate, which occurs naturally in many types of vegetable, reduces accumulation of fat in the liver.

Strong committed relationships can reduce military suicides

Can being in a strong committed relationship reduce the risk of suicide? Researchers at Michigan State University believe so, especially among members of the National Guard.

New bacterial species may help fight obesity and metabolic disorders

The MyNewGut project has discovered new bacterial species and strains in healthy people that seem to be effective against obesity, metabolic and mental disorders related to stress and obesity (e.g. depression).
