Knocking out lipid-modifying enzyme can boost post-heart attack healing, study shows

Two immune responses are important for recovery after a heart attack - an acute inflammatory response that attracts leukocyte immune cells to remove dead tissue, followed by a resolving response that allows healing.

Researchers develop highly sensitive method to detect early stages of colorectal cancer

A highly sensitive method that can detect even the earlier stages of colorectal cancer has been developed by researchers in Japan. Shimadzu Corporation, the Kobe University Graduate School of Medicine, and the National Cancer Center in Japan have collaborated to develop a new screening method that comprehensively analyzes the metabolites in our blood.

Abnormal levels of specific gut bacteria linked to chronic fatigue syndrome

Scientists at the Center for Infection and Immunity at Columbia University's Mailman School of Public Health have discovered abnormal levels of specific gut bacteria related to chronic fatigue syndrome/myalgic encephalomyelitis, or ME/CFS, in patients with and without concurrent irritable bowel syndrome, or IBS.

Genetic factors may increase person's risk for adverse effects of synthetic cannabinoids

Synthetic cannabinoid abuse is a growing problem in the United States, with new versions of the drugs coming on the market every year. New research is examining how the body processes these man-made drugs and the role that genetics might play in their metabolism.

How physicians can prevent opioid abuse while providing adequate pain relief

Rather than being considered a miracle pill that magically takes away pain, prescription opioids are increasingly being seen as a precursor to heroin addiction and the cause of potentially deadly overdoses themselves.

Vanderbilt geneticists find new way to tap plant pharmacopeia to produce improved therapeutics

Cocaine, nicotine, capsaicin. These are just three familiar examples of the hundreds of thousands of small molecules (also called specialized or secondary metabolites) that plants use as chemical ammunition to protect themselves from predation.

Metabolite produced by intestinal bacteria protects against type 2 diabetes, study shows

A high concentration of indolepropionic acid in the serum protects against type 2 diabetes, shows a new study from the University of Eastern Finland. Indolepropionic acid is a metabolite produced by intestinal bacteria, and its production is boosted by a fibre-rich diet.

Unique metabolic ‘signature’ in urine may help predict development of diabetes in obese teenagers

Researchers have discovered a unique metabolic "signature" in the urine of diabetic, obese black teenagers that they say may become a way to predict the development of type 2 diabetes in people at risk.

Study reveals intriguing crosstalk between metabolism and epigenetics in cancer development

A study published in Briefings in Functional Genomics investigated how epigenetics can modulate human's genetic program -- it can emphasize or silence genes.

Researchers probe potential link between gut microbiota and poor artery health

Scientific evidence that the assortment of gut microbes in humans influences different and critical aspects of health is piling up: Researchers think our microbes may influence obesity, anxiety, depression, autism, cancer and gastrointestinal diseases.

Decoding the Exposome Through Breath Biomarkers

The human exposome is probably best defined as “everything that is not the genome.” This is a bit tongue in cheek, but basically, the exposome is comprised of all of the chemicals in your body from the environment, food, consumer products, their metabolites, the endogenous “housekeeping” chemicals, the cellular wastes from energy production, as well as all of the messenger compounds and life supporting chemicals.

Researchers develop new tool that quickly reveals metabolic fluxes in cells

If we were to take photographs at the underground stations in Barcelona, we would see the number of people waiting, find out what time the rush hour takes place and deduce why some stations are busier than others.

Duke Health scientists identify proteins in mucous that confirm viral infection

It may seem obvious, but the key to confirming whether someone is suffering from a cold or flu virus might lie at the misery's source -- the inflamed passages of the nose and throat.
