Dietary changes may prevent or reverse age-related effects in the brain

A study using neuroimaging led by Stony Brook University professor and lead author Lilianne R. Mujica-Parodi, PhD, and published in PNAS, reveals that neurobiological changes associated with aging can be seen at a much younger age than would be expected, in the late 40s.

Older workers with obesity at higher risk of prolonged sickness absence or job loss

New research has shown that older workers with obesity are at a higher risk of prolonged sickness absence or losing their jobs for health reasons than those of normal weight, with women affected significantly more than men.

Chemists develop promising molecular tool to target cell immortality's underlying gears

One of the hallmarks of cancer is cell immortality. A Northwestern University organic chemist and his team now have developed a promising molecular tool that targets and inhibits one of cell immortality's underlying gears: the enzyme telomerase.

Observation of telomerase activity at a single-molecule level using 'optical tweezers'

Stem cells involved in replenishing human tissues and blood depend on an enzyme known as telomerase to continue working throughout our lives. When telomerase malfunctions, it can lead to both cancer and premature aging conditions.

Rapamycin worsens diseases and premature aging in mice with short telomeres

In the past few decades, it was discovered that the rate at which we age is strongly influenced by biochemical processes that, at least in animal models, can be controlled in the laboratory.

New tool may benefit frail patients in multi-hospital health systems

Frail patients in private-sector, multi-hospital health systems may benefit from a tool that can quickly predict their risk for poor outcomes following surgery, including postoperative mortality, readmission and extended hospital stays.

New tool allows researchers to peer into live tissue of the fruit fly gut

They say a picture is worth 1,000 words. But what about a real-time window into the complexity of the gastrointestinal system?

Alzheimer's could be detected early using a blood test

Researchers from the ARTFL-LEFFTDS Longitudinal Frontotemporal Lobar Degeneration (ALLFTD) research consortium, have reported that a blood test could soon be an important diagnostic tool in detecting the abnormal proteins deposits in the brain that lead to the progressive and debilitating condition of Alzheimer's disease. The study titled, "Diagnostic value of plasma phosphorylated tau181 in Alzheimer's disease and frontotemporal lobar degeneration," was published in today's issue of the journal Nature Medicine.

New blood test could be deployed in primary care setting for people with memory issues

A blood test that may eventually be done in a doctor's office can swiftly reveal if a patient with memory issues has Alzheimer's disease or mild cognitive impairment and can also distinguish both conditions from frontotemporal dementia.

Study reports advance in blood test to detect accumulation of Alzheimer's protein in the brain

Researchers report an advance in the development of a blood test that could help detect pathological Alzheimer's disease in people who are showing signs of dementia.

Length of pregnancy related to chemical DNA changes in newborns

Researchers from Karolinska Institutet in Sweden have together with an international team mapped the relationship between length of pregnancy and chemical DNA changes in more than 6,000 newborn babies.

Canada's cancer burden will increase in 2020 as population ages

Nearly 1 in 2 Canadians are expected to receive a diagnosis of cancer in their lifetime, and cancer is the leading cause of death in the country.

Microglia play a dual role in regulating the permeability of blood-brain barrier, study shows

The blood-brain barrier is a layer of cells that covers the blood vessels in the brain and regulates the entry of molecules from the blood into the brain.

New templates for improving assessment of senior cancer patients

While older adults, defined as those 65 and older, make up the largest percentage of cancer patients and survivors, this group is not adequately represented in clinical trials, research at the University of Cincinnati has shown.

Study shows how cellular filament helps neural stem cells clear damaged, clumped proteins

New research by University of Wisconsin-Madison scientists reveals how a cellular filament helps neural stem cells clear damaged and clumped proteins, an important step in eventually producing new neurons.

Eating less prolongs life

A new study published in the journal Cell in February 2020 reports that eating less is associated with better immunity, reduce inflammation all over the body, and reduced odds of diseases related to old age, as well as increasing the odds of living longer.
