Acidic environment enhances production of butyric acid from apple pectin by fecal microbiota

Researchers from Tallinn University of Technology, Grete Raba, Signe Adamberg, and Kaarel Adamberg showed that an acidic environment enhances the production of butyric acid from apple pectin by fecal bacterial consortia - microbiota.

Why SARS-CoV-2 delta variant is more infectious

German experts recently explained why the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) delta variant is more infectious and pathogenic than its ancestor. By conducting a series of in vitro experiments, they have revealed that increased ability to induce cell-to-cell fusion (syncytia) and reduced susceptibility to vaccine and infection-induced antibodies make the delta variant more infectious than previously circulating variants. The study is currently available on the bioRxiv* preprint server.

New dietary fiber formulation improves the potency of cancer immunotherapies

Many people don't realize that the trillions of bacteria, viruses, and fungi residing within the gastrointestinal tract--collectively called the gut microbiome-- are connected to overall health, and specifically to cancer.

Could type III interferons be used as a SARS-CoV-2 therapeutic?

Researchers have found that both type I and type III interferons can inhibit SARS-CoV-2 infection in human intestinal cells, but type III interferons can act faster and for a longer period, making them suitable for potential therapeutics.

Macrophages can aid tumor growth by distracting cancer-killing CD8+ T cells

A Ludwig Cancer Research study adds to growing evidence that immune cells known as macrophages inhabiting the body cavities that house our vital organs can aid tumor growth by distracting the immune system's cancer-killing CD8+ T cells.

Lack of screening may be behind the increased risk of colon cancer among Black people

Black people have a higher risk of colorectal cancer than white people, but this risk is likely not due to genetics.

Common antidepressant drugs help the immune system to attack tumors in mice

A class of drug called monoamine oxidase inhibitors is commonly prescribed to treat depression; the medications work by boosting levels of serotonin, the brain's "happiness hormone."

Study reveals how high fat diets can cause intestinal and colon cancer

For decades, physicians and dieticians have urged people to limit their intake of high fat foods, citing links to poor health outcomes and some of the leading causes of death in the U.S., such as diabetes, heart disease and cancer.

New bacterium shows promise for treating type 2 diabetes, obesity

It all started, when Patrice Cani, FNRS researcher at University of Louvain (UCLouvain), and his team repeatedly observed that a bacterium (called Subdoligranulum) is almost absent in obese and diabetic people, while it is systematically present in healthy people. So, they decided to take a closer look at this "family" of bacteria.

Study confirms the importance of low-protein, high-carbohydrate diet

Researchers at the University of Sydney's Charles Perkins Centre conducted the largest ever study of nutrient interactions by examining the health of mice on 33 different diets containing various combinations of protein to carbs, and different sources of carbohydrate.

New national screening guidelines on colorectal cancer

Most Americans should get screened for colorectal cancer beginning at age 45 instead of age 50, according to new recommendations from the U.S. Preventive Services Task Force, which includes UVA Health's Li Li, MD, PhD, MPH.

Researchers to develop new technology to detect and remove cancer tumors

New technology that will marry probes that can detect cancer tumors through the skin with high-precision robotic surgery is to be developed for use in hospital settings for the first time in a project led by the University of Warwick.

BMI may not be best obesity indicator to evaluate lung cancer risk, study suggests

New research published in the Journal of Thoracic Oncology suggests the method used to calculate how obesity is measured may affect whether it is considered a risk factor for lung cancer.

“Good” bacteria demonstrate clinical potential for treating ulcerative colitis, Crohn's disease

A new study published in Nature Communications demonstrates that a consortium of bacteria designed to complement missing or underrepresented functions in the imbalanced microbiome of inflammatory bowel disease (IBD) patients, prevented and treated chronic immune-mediated colitis in humanized mouse models.

New microbial genes responsible for bile acid conversion is a major step forward for gut health

As the owner of a human body, you're carrying trillions of microbes with you everywhere you go. These microscopic organisms aren't just hitching a ride; many of them perform essential chemical reactions that regulate everything from our digestion to our immune system to our moods.

Should colorectal cancer screening start at age 45?

Colorectal cancer rates among young adults are steadily increasing over the years. The United States Task Force has long recommended that people aged 50 to 75 get screened. Now, the U.S. Preventive Services Task Force updated its 2016 recommendation of colorectal screening for people aged 50, down to 45 years old. The five-year earlier screening can save many lives by allowing earlier diagnosis and treatment of the condition.

Researchers link “genetic signatures” of bacteria in the human gut to multiple diseases

We are truly never alone, not even within our own bodies. Human beings play host to trillions of bacteria, fungi, viruses, and other microorganisms that make up the human microbiome.

Cancer patients without health insurance had significantly worse survival than Medicare beneficiaries

MUSC Hollings Cancer Center lung cancer researcher Gerard Silvestri, M.D., found that a lack of insurance leads to worse cancer survival than for those with Medicare, in a paper published in the May issue of Health Affairs.

Insured cancer patients treated at Kaiser Permanente have better survival rates

Among cancer patients with health coverage in Southern California, those who were diagnosed and treated at Kaiser Permanente, an integrated health care organization, had better survival rates, especially Black and Latino patients, according to Kaiser Permanente research published in The American Journal of Managed Care.
