People with major depressive disorder have reduced arginine levels, study shows

People suffering from major depressive disorder, MDD, have reduced arginine levels, a new study from the University of Eastern Finland shows. Arginine is an amino acid which the body uses to produce, e.g., nitric oxide.

Scientists explore connection between bad sleep habits and stiff blood vessels

What do bad sleep habits and stiff blood vessels have in common? Nothing good, say scientists exploring what appears to be a direct connection between a circadian clock that isn't working as it should and an enzyme that promotes inflammation working overtime.

Psoriasis drug also effective at reducing aortic inflammation

Ustekinumab, sold under the name Stelara, is approved by the U.S. Food and Drug Administration to treat psoriasis, psoriatic arthritis, and Crohn's Disease. Researchers wanted to know if the benefits of the drug go beyond clearing the skin.

Biomedical engineers grow living windpipe structures from self-assembled modules

Biomedical engineers at Case Western Reserve University are growing tracheas by coaxing cells to form three distinct tissue types after assembling them into a tube structure - without relying on scaffolding strategies currently being investigated by other groups.

Scientists discover adult endothelial stem cells capable of generating fully functional blood vessels

The proper function of blood vessels is essential to life: blood vessels are responsible for transporting oxygen-rich red blood cells, nutrients, and immune cells throughout the body, to name just a few functions. Defects in blood vessels can correspondingly lead to a variety of life-threatening diseases.

Researchers detail molecular atlas of cells that form brain's blood vessels

Even though diseases of the brain vasculature are some of the most common causes of death in the West, knowledge of these blood vessels is limited.

Mice study raises hope to successfully treat Alzheimer's disease

A team of researchers from the Cleveland Clinic Lerner Research Institute have found that gradually depleting an enzyme called BACE1 completely reverses the formation of amyloid plaques in the brains of mice with Alzheimer's disease, thereby improving the animals' cognitive function.

Climbing stairs reduces hypertension and strengthens muscles, find study

New research published in the journal Menopause found that climbing stairs helps lower blood pressure and strengthens leg muscles in postmenopausal women.

Oncolytic virus alerts the immune system to attack tumors

A new UC San Francisco study has shown that a cancer-killing virus currently in clinical trials may function as a cancer vaccine - in addition to killing some cancer cells directly, the virus alerts the immune system to the presence of a tumor, triggering a powerful, widespread immune response that kills cancer cells far outside the virus-infected region.

Stair climbing lowers blood pressure and builds leg strength in postmenopausal women

If you don't have the time or money for aerobic and resistance training, why not try climbing the stairs? A new study demonstrates that stair climbing not only lowers blood pressure but also builds leg strength, especially in postmenopausal women with estrogen deficiencies who are more susceptible to vascular and muscle problems.

New ECPR alert helps some people survive fatal cardiac arrest

More people are walking away from a type of cardiac arrest that is nearly always fatal, thanks to a new protocol being tested at The Ohio State University Wexner Medical Center. It's called an ECPR alert.

Five minute treadmill test can predict risk of mortality, research finds

Queen's University researcher Louise de Lannoy has determined a short, five minute treadmill test can predict the risk of mortality. This risk is determined independent of other traditional risk factors including age, weight, blood pressure, smoking status, diabetes, cholesterol, and family history.

People who survive childhood heart defects may be at elevated risk of developing dementia

People born with heart defects who survive into adulthood may be at higher risk of developing dementia, particularly dementia that starts before 65 years of age, according to new research in the American Heart Association's journal Circulation.

Study finds new stem cell pathway that allows triple-negative breast cancer to thrive

Cleveland Clinic researchers have published findings in Nature Communications on a new stem cell pathway that allows a highly aggressive form of breast cancer - triple-negative breast cancer - to thrive.

Researchers describe human blood-nerve barrier transcriptome for the first time

Human peripheral nerves -- all the nerves outside of the central nervous system -- are protected by the blood-nerve barrier. This is a tight covering of endothelial cells that maintains the microenvironment within the nerves by restricting the amounts or types of water, ions, solutes and nutrients that can reach the axons, or electric cables within the nerves, from the blood circulation system.
