Turning microbiome research into a force for health

The microbiome comprises trillions of microorganisms living on and inside each of us. Historically, some researchers have guessed at its role in human health, but in the last decade or so genetic sequencing techniques have illuminated this galaxy of microorganisms enough to study it in detail. As researchers unravel the […]

Study Explains Why Patients with Cancer Spread to the Liver Have Worse Outcomes

Michael Green, M.D., PhD, noticed that when his patients had cancer that spread to the liver, they fared poorly – more so than when cancer spread to other parts of the body. Not only that, but transformative immunotherapy treatments had little impact for this patient. Uncovering the reason and a […]

Research shows a few beneficial organisms could play key role in treating type 2 diabetes

Researchers at Oregon State University have found that a few organisms in the gut microbiome play a key role in type 2 diabetes, opening the door to possible probiotic treatments for a serious metabolic disease affecting roughly one in 10 Americans. “Type 2 diabetes is in fact a global pandemic […]

Hopping electrons help re-route harmful diseases

The simple act of breathing is among the most familiar ways we convert nutrients to energy – inhaling molecules of oxygen and harmlessly breathing out unwanted material. But when our usual disposal mechanisms fail, the accumulated electrons can produce the kind of toxic event that causes many diseases, including cancer. […]

High blood pressure at any age, no matter how long you have it, may speed cognitive decline

High blood pressure appears to accelerate a decline in cognitive performance in middle-aged and older adults, according to new research published today in Hypertension, an American Heart Association journal. Nearly half of American adults have high blood pressure or hypertension. Having high blood pressure is a risk factor for cognitive […]

Resveratrol is Not an Effective Calorie Restriction Mimetic

Resveratrol and derived molecules were for a time excessively hyped as a means to trigger some of the beneficial metabolic response produced by calorie restriction, by acting on sirtuins, and thus have a positive impact on aging. The company Sirtris was founded to develop this area of research into a […]

A Proof of Concept Attempt to Assess the Impact of First Generation Senolytic Drugs by Looking at Past Usage

Senolytic drugs are those capable of selectively destroying senescent cells. A range of such therapies are at various stages of development, including those that have reached initial human clinical trials. Senescent cell accumulation is an important cause of degenerative aging, and the removal of such cells via senolytic treatments has […]

Axin for a friend: Protein could hold the key to longer, healthier life

Axin is a VIP – a Very Important Protein. It’s essential to the development of an embryo. It’s a key player in allowing the body’s cells to divide without going haywire and forming a tumour. It regulates the body’s production of lipids, or fats, which can affect aging. Essentially, it […]

A pursuit of better testing to sort out the complexities of ADHD

The introduction of computer simulation to the identification of symptoms in children with attention-deficit/hyperactivity disorder (ADHD) has potential to provide an additional objective tool to gauge the presence and severity of behavioural problems, Ohio State University researchers suggest in a new publication. Most mental health disorders are diagnosed and treated based […]

NIH study uncovers blood vessel damage and inflammation in COVID-19 patients’ brains but no infection

In an in-depth study of how COVID-19 affects a patient’s brain, National Institutes of Health researchers consistently spotted hallmarks of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly after contracting the disease. In addition, they saw no signs of SARS-CoV-2 in […]

Study details how aerobic exercise reverses degenerative process that leads to metabolic diseases

Experiments with mice and humans showed that exercise training increased the expression in adipose tissue of a key enzyme for the organism's metabolic health, combating the harmful effects of aging and obesity. Adipose tissue is not just a simple reservoir of energy for periods of food scarcity. It contributes significantly […]

Frailty Is a Factor in Higher Mortality for Women Awaiting Liver Transplants

Women awaiting liver transplants in the United States are known to be about one-third more likely than men to become too ill to undergo surgery or die before receiving a liver. Now a study headed by UC San Francisco and Columbia University highlights the role that frailty plays in this […]

Microbiome study: Gum disease-causing bacteria borrow growth molecules from neighbors to thrive

The human body is filled with friendly bacteria. However, some of these microorganisms, such as Veillonella parvula, may be too nice. These peaceful bacteria engage in a one-sided relationship with pathogen Porphyromonas gingivalis, helping the germ multiply and cause gum disease, according to a new University at Buffalo-led study. The […]

Stopping RAS inhibitors tied to worse outcomes in patients with advanced chronic kidney disease

Small studies have suggested that a group of medications called RAS inhibitors may be harmful in persons with advanced chronic kidney disease, and physicians therefore often stop the treatment in such patients. Researchers at Karolinska Institutet now show that although stopping the treatment is linked to a lower risk of […]

COVID-19 Affects the Brain by Crossing the Blood-Brain Barrier, Evidence Strongly Suggests

In a new study led by the University of Washington School of Medicine, researchers demonstrate that SARS-CoV-2 – the pathogen behind COVID-19 disease – can enter the brain of mice, just like many other viruses before it. People who develop COVID-19 often experience intense bodily inflammation called a cytokine storm, […]

The Body is a Network: Cell Signaling in Age-Slowing Interventions

The authors of this open access papers discuss the prominent role of cell signaling in the better known classes of intervention that have been shown to slow aging in worms, flies, and mice. The body is a network in which cells in one tissue influence the behavior of cells in […]

Study links metabolic syndrome to higher cardiovascular risk in patients with psoriasis

Psoriasis, a chronic inflammatory skin disease, has long been known to increase the risk of cardiovascular disease, which includes heart attack and stroke. Now, researchers have identified a key culprit: the presence of metabolic syndrome (MetSyn), a condition that includes obesity, diabetes, high cholesterol, and hypertension, and is highly prevalent […]

AI-powered microscope could check cancer margins in minutes

When surgeons remove cancer, one of the first questions is, “Did they get it all?” Researchers from Rice University and the University of Texas MD Anderson Cancer Center have created a new microscope that can quickly and inexpensively image large tissue sections, potentially during surgery, to find the answer. The […]
