AIDS patients suffer higher rates of cancer because they have fewer T-cells in their bodies to fight disease. But new research examines why HIV-infected patients have higher rates of cancer—among the leading causes of death among that population—than the general population. Researchers at Case Western Reserve University’s School of Dental […]

Older patients with a diagnosis of chronic sinusitis — a disease of the nasal cavity and paranasal sinuses that often persists over many years — have a unique inflammatory signature that may render them less responsive to steroid treatment, according to a new study published by Vanderbilt researchers. The study […]

Although chemotherapy can kill cancer cells very effectively, healthy cells also suffer. If doctors could remove excess chemotherapy drugs from a patient’s bloodstream after the medicines have done their job, they might reduce side effects such as hair loss and nausea. Now, researchers have developed a 3D-printed device that absorbs […]

We often design and build genetic devices in isolation and then bring the plasmids encoding them together in one cell; most of the time this results in an unexpected behavior. The devices function differently when sharing the same cell than they did when alone. Recent work suggests that this is, […]

For patients affected by systemic scleroderma (also known as systemic sclerosis), a chronic autoimmune disease marked by hardening of the skin and internal organ involvement, the need for treatments is well understood. “Scleroderma has the highest mortality rates of any rheumatic disease,” says Dinesh Khanna, M.D., M.Sc., director of the Michigan Medicine Scleroderma Program. “This […]

A new study from Harvard Medical School researchers at Massachusetts General Hospital has found that the hypertension drug losartan, which targets the angiotensin signaling pathway, may improve the effectiveness of chemotherapy agents used to treat ovarian cancer. Previous research from the same team identified a similar effect for losartan in […]

Using a novel patient-specific stem cell-based therapy, researchers at the National Eye Institute (NEI) prevented blindness in animal models of geographic atrophy, the advanced “dry” form of age-related macular degeneration (AMD), which is a leading cause of vision loss among people age 65 and older. The protocols established by the […]

Nerve axons serve as the wiring of the nervous system, sending electrical signals that control movement and sense of touch. When axons are damaged, whether by injury or as a side effect of certain drugs, a program is triggered that leads axons to self-destruct. This destruction likely plays an important […]

Scientists working to develop more effective treatments for diabetes are turning to stem cells. Such cells can be transformed into cells that produce insulin, the hormone that controls blood sugar. But there’s a major challenge: the amount of insulin produced by theses cells is difficult to control. Now, by tweaking […]

Up to 20 percent of women develop gestational diabetes – high blood sugar – during pregnancy, but the long-term effects on their children haven’t been known. Now, the first study to analyze the long-term effects found the 10-to-14-year-old children of women who had untreated gestational diabetes are more likely to […]

Early adult general cognitive ability (GCA) — the diverse set of skills involved in thinking, such as reasoning, memory and perception — is a stronger predictor of cognitive function and reserve later in life than other factors, such as higher education, occupational complexity or engaging in late-life intellectual activities, report […]

Young adults in the U.S. are engaging in binge drinking later into their 20s, according to a recent analysis from the long-term Monitoring the Future study that has tracked the attitudes and behaviors of young adults since the 1970s. The analysis, led by University of Minnesota Professor Megan Patrick, Ph.D., was recently published in […]

Many people nowadays are experiencing sleeping problems. Sometimes it is difficult to fall asleep and sometimes it is actually difficult to get some rest. A new study from the University of Adelaide revealed that older men who are suffering from extended episodes of interrupted breathing while asleep have a high […]

Hundreds of thousands of deaths every year can be traced back to hypertension, better known simply as high blood pressure. This condition plays a role in such diseases as heart attack, kidney disease and stroke. Now a team of scientists led by the University of Edinburgh discovered that a particular […]

Research scientists around the world are now able to investigate the structural, cellular and developmental intricacies of the human brain using bioengineered stem cell-based models called organoids.
