SDF-1 turns on autophagy that helps cells stay in place and focused on making bone

A signaling molecule that helps stem cells survive in the naturally low-oxygen environment inside the bone marrow may hold clues to helping the cells survive when the going gets worse with age and disease, researchers report.

New study shows emotions affect health and wellness in low-income countries

Positive emotions are known to play a role in physical well-being, and stress is strongly linked to poor health, but is this strictly a "First World" phenomenon?

Genetic mutation that alters PIEZO1 ion channel in RBCs contributes to familial xerocytosis

A genetic mutation that alters the kinetics of an ion channel in red blood cells has been identified as the cause behind a hereditary anemia, according to a paper published this month in the Proceedings of the National Academy of Sciences by University at Buffalo scientists and colleagues.

Tako-tsubo cardiomyopathy can also be deadly when compounded by other co-morbidities

Even though a newly recognized cardiomyopathy, which mainly impacts women, is typically treatable, Tako-tsubo cardiomyopathy can also be deadly when compounded by other co-morbidities, such as heart failure, according to a study being presented March 9 at the American College of Cardiology (ACC) Scientific Sessions.

Viruses and genes may increase risk of schizophrenia

Viruses and genes interact in a way that may increase the risk of developing schizophrenia significantly. This happens already in the developing foetus.

Researchers identify enzymes that can regulate activity of medically important proteins

Protein activity is strictly regulated. Incorrect or poor protein regulation can lead to uncontrolled growth and thus cancer or chronic inflammation. Members of the Institute of Veterinary Biochemistry and Molecular Biology from the University of Zurich have identified enzymes that can regulate the activity of medically important proteins.

Cardiovascular disease risk in women higher than you think

In conjunction with International Women's Day, the European Cardiology Society reminds women that they may be at a greater risk for cardiovascular disease (CVD) than they think.

Researchers uncover cellular-level detail of what happens when bone bears stress over time

From athletes to individuals suffering from osteoporosis, bone fractures are usually the result of tiny cracks accumulating over time -- invisible rivulets of damage that, when coalesced, lead to that painful break.

Weill Cornell receives NIMH grant to discover novel biomarkers for chronic fatigue syndrome

Weill Cornell Medical College has been awarded more than $1.9 million by the National Institute of Mental Health of the National Institutes of Health to lead an innovative research study using advanced neuroimaging and clinical evaluations of patients with chronic fatigue syndrome (CFS).

Cardiac rehab program may reduce death rate in women with coronary artery disease

Women with coronary artery disease who completed a 12-week cardiac rehabilitation program were two-thirds less likely to die compared to those who were not referred to the program.

Patients with PTSD more likely to develop insulin resistance, metabolic syndrome and heart disease

Patients diagnosed with post-traumatic stress disorder (PTSD) have a significantly higher risk of developing insulin resistance and metabolic syndrome, placing them at greater risk for heart disease and diabetes, according to research being presented at the American College of Cardiology's 62nd Annual Scientific Session. Researchers say public health interventions are urgently needed to prevent PTSD-related metabolic disorder at its early, reversible stage.

Upheaval caused by Hurricane Katrina seems to have disrupted heart attack timing

The upheaval caused by Hurricane Katrina seems to have disrupted the usual timing of heart attacks, shifting peak frequency from weekday mornings to weekend nights, in a change in pattern that persisted a full five years after the storm, according to research being presented at the American College of Cardiology's 62nd Annual Scientific Session.

Toshiba introduces Aplio 500 and 300 CV ultrasound systems

To help clinicians more accurately and efficiently diagnose cardiovascular disease, Toshiba America Medical Systems, Inc. introduces the Aplio 500 and Aplio 300 CV ultrasound systems.

Researchers discover significant crisis-period spike in heart attacks in Greece

Heart attack rates have spiked in Greece since the start of the country's financial crisis, especially among women and residents older than 45, according to a study of patient records being presented at the American College of Cardiology's 62nd Annual Scientific Session.

Exercise may play a key role in helping children cope with stressful situations

Exercise may play a key role in helping children cope with stressful situations, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

African-American women with breast cancer more likely to develop heart failure

African-American women who survive breast cancer are more likely to develop heart failure than other women who have beaten the disease, according to research being presented at the American College of Cardiology's 62nd Annual Scientific Session.

SRSF1 protein can prevent cancerous proliferation by stabilizing p53

Some cellular proteins have multiple, and occasionally opposing, functions. Professor Adrian Krainer and colleagues at Cold Spring Harbor Laboratory demonstrate in a paper published online today in Molecular Cell that the oncogenic protein SRSF1 can also trigger a stop in cell growth and prevent cancerous proliferation by stabilizing p53, the powerful tumor-suppressor protein.

New Orleans residents continue to face increased risk of heart attack post-Katrina

New Orleans residents continue to face a three-fold increased risk of heart attack post-Katrina-a trend that has remained unchanged since the storm hit in 2005, according to research being presented at the American College of Cardiology's 62nd Annual Scientific Session.
