Immune system may mount an attack in Parkinson’s disease

A new study suggests that T cells, which help the body’s immune system recognize friend from foe, may play an important role in Parkinson’s disease (PD). The study, published in the journal Nature, was supported by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes […]

Not just hot flashes: Research reveals need to address range of symptoms in midlife women

When women reach “a certain age” they expect some typical symptoms that signal their journey through menopause. New research from the University of Michigan shows symptoms often cluster, and how they do so can suggest who is at risk for health problems and which women likely will experience healthy aging. […]

UCI stem cell therapy attacks cancer by targeting unique tissue stiffness

A stem cell-based method created by University of California, Irvine scientists can selectively target and kill cancerous tissue while preventing some of the toxic side effects of chemotherapy by treating the disease in a more localized way. Weian Zhao, associate professor of pharmaceutical sciences, and colleagues have programmed human bone […]

Scientists regenerate retinal cells in mice

Scientists have successfully regenerated cells in the retina of adult mice at the University of Washington School of Medicine in Seattle. Their results raise the hope that someday it may be possible to repair retinas damaged by trauma, glaucoma and other eye diseases. Their efforts are part of the UW […]

Risk for bipolar disorder associated with faster ageing

The study, published in Neuropsychopharmacology, also shows that bipolar patients treated with lithium – the main medication for the illness – have longer telomeres (a sign of slower biological ageing) compared to bipolar disorder patients not treated with lithium. This suggests that the drug may mask the ageing effects associated with bipolar […]

Study may lead to new diagnostic and prognostic tools for HIV-associated neurocognitive disorders

UAlberta researchers believe they now have a clearer picture of why people living with HIV so commonly suffer from dementia and other neurocognitive disorders. Researchers compared the brain tissue of 10 HIV patients with no neurological symptoms to the brain tissue of 20 patients suffering from HIV-associated neurocognitive disorders (HAND), […]

A healthy lifestyle increases life expectancy by up to seven years

People who do not smoke, are not obese, and consume alcohol moderately can expect to live seven years longer than the general population, and to spend most of these extra years in good health, according to a new study published in Health Affairs. A new study published in Health Affairs shows that people who […]

Engineered liver tissue expands after transplant

Many diseases, including cirrhosis and hepatitis, can lead to liver failure. More than 17,000 Americans suffering from these diseases are now waiting for liver transplants, but significantly fewer livers are available. To help address that shortage, researchers at MIT, Rockefeller University, and Boston University have developed a new way to […]

New findings suggest a genetic influence on aging into the 90s but not beyond

Variants of a gene thought to be linked to longevity appear to influence aging into the 90s, but do not appear to affect exceptional longevity, or aging over 100, a new study has found. The research challenges previous findings that indicated some variants of the gene, FOXO3, played a role […]

Tracking the mechanisms of artery formation

Arteriogenesis is a critical event – not only during development but also in adult life. Cardiovascular life-threatening events, triggered by disease, could be overcome by alternatives to existing therapies, for example by inducing the formation of new arteries. However, the mechanisms of artery formation are not well understood. A team […]

Advance furthers stem cells for use in drug discovery, cell therapy

Since highly versatile human stem cells were discovered at the University of Wisconsin–Madison nearly 20 years ago, their path to the market and clinic has been slowed by a range of complications. Both embryonic stem cells and induced pluripotent stem cells are valued for their ability to form any cell […]

Innovative skin replacement starts final clinical trial

A University of Wisconsin–Madison spinoff that makes an innovative material designed to speed healing of serious burns has begun a large clinical trial for the “regenerative skin tissue” it has been developing since 2000. Stratatech, now a Mallinckrodt Pharmaceuticals company, aims to prove to the Food and Drug Administration that the material, […]

Fighting Cancer: Natural and Synthetic Progestin Therapies in Post-Menopausal Women Help Breast Cancer Grow and Spread

Hormone replacement therapies, or medications containing female hormones that substitute those no longer produced by the body, often are prescribed to reduce the effects of menopausal symptoms in women. Research has indicated that women who take hormone replacement therapies have a higher incidence of breast cancer. Now, researchers at the […]

Stem cell advance brings bioengineered arteries closer to reality

Stem cell biologists have tried unsuccessfully for years to produce cells that will give rise to functional arteries and give physicians new options to combat cardiovascular disease, the world’s leading cause of death. But new techniques developed at the Morgridge Institute for Research and the University of Wisconsin–Madison have produced, […]

Smart children live longer – how did scientists figure this one out?

There is an old saying that being smart is bad for you. Smarter people are usually less social and more often suffer from depression and anxiety. However, there are many advantages of being more intelligent. Scientists from The University of Edinburgh have conducted a research, which showed that children with […]

3D bone-like tissues made from pluripotent stem cells

Researchers at the University of Tokyo have developed a cell culture method that generates three-dimensional bone-like tissues from mouse pluripotent stem cells—cells which can differentiate into various tissue types and have infinite growth potential—using only small molecules, in given conditions, as inducers. The current result serves as a step toward […]

Dementia patients may die sooner if family caregivers are mentally stressed

Patients with dementia may actually die sooner if their family caregivers are mentally stressed, according to a new UC Berkeley study. From 2007 until 2016, UC Berkeley researchers tracked the mortality of 176 patients with neurodegenerative diseases that are corrosive to brain function. They also measured the mental health of […]

Long-term aspirin use linked to bleeding risk in over 75s

While short-term aspirin use after a stroke or heart attack has clear benefits, the authors say that patients over 75 who take aspirin on a daily basis should be prescribed a proton-pump inhibitor (heartburn drugs) to reduce the risk of bleeding. Roughly 40-60% of adults aged 75 or older in […]
