Digestion is the mechanical and chemical breaking down of food into smaller components, to a form that can be absorbed, for instance, into a blood stream. Digestion is a form of catabolism; a break-down of macro food molecules to smaller ones.
Calm body, calm mind, say the practitioners of mindfulness. A new study by researchers at Washington University School of Medicine in St. Louis indicates that the idea that the body and mind are inextricably intertwined is more than just an abstraction.
A team of UCF College of Medicine researchers has created a digital topographical map of the cardiac sympathetic neural network, the region that controls the body's heart rate and its "fight-or-flight" response.
Antibiotics help to fight bacterial infections, but they can also harm the helpful microbes living in the gut, which can have long-lasting health consequences.
According to a new study performed at the Earlham Institute and Quadram Institute in Norwich, the community of microbes living in and on human bodies might be serving as a reservoir for antibiotic resistance.
New research suggests that diversity in genes implicated in immunity might have facilitated the shift from hunter-gatherer lifestyles to agriculture that occurred in prehistoric Europe over the course of around 1,500 years.
Combining discoveries in cancer immunology with sophisticated genetic engineering, Columbia University researchers have created a sort of "bacterial suicide squad" that targets tumors, attracting the host's own immune cells to the cancer to destroy it. The new work, published today in Science Advances, marks a major step forward in efforts to enlist non-pathogenic bacteria to combat cancer.
A tiny worm called the C. elegans is enabling scientists to explore the emerging theory that Parkinson's disease starts in the gut.
A vibrating capsule designed to stir the colon to action appears to double the ability for adults struggling with debilitating chronic constipation to defecate more normally and without drugs, researchers report.
Baby kangaroo feces might help provide an unlikely solution to the environmental problem of cow-produced methane.
Scientists at the State University of Campinas (UNICAMP) and the Federal University of the ABC (UFABC) in São Paulo state, Brazil, have successfully produced biogas from apple pomace, the pulpy residue remaining after the fruit has been crushed to extract its juice.
Pep-tRNAs, nascent polypeptides inside the ribosome that are covalently connected to transfer RNA, are engaged in a variety of cell processes, including gene expression, according to advances in molecular biology.
Tech companies have developed many devices that work outside the body, such as cell phones, smart watches, tablets and hundreds of others. Inside the body, though? That's obviously trickier for several reasons, but power for a device is a big one.
Engineering researchers have developed a battery-free, pill-shaped ingestible biosensing system designed to provide continuous monitoring in the intestinal environment.
A team of Duke researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with the Neanderthals.
An essential component of the Arctic food chain is polar fish. Along with colleagues from KU Leuven and the Alfred Wegener Institute, Sarah Maes (KU Leuven) and Fokje Schaafsma (Wageningen Marine Research) examined the diet of polar cod from the Barents Sea.
Quark and cheese are primarily casein-based in terms of protein content. The stomach’s digestion of casein results in the production of protein fragments (peptides) that have an unpleasant flavor, despite casein itself not having a bitter flavor.
By helping with digestion, supplying nutrients and metabolites, and collaborating with the immune system to ward off pathogens, gut bacteria have a significant impact on health.
The cells’ proteins contain a huge world of information that, when unlocked, can shed light on the causes of many fundamental biological occurrences. To observe the properties of individual cells at the protein level, a single-cell analysis method known as “single-cell proteomics” is used.
A stomach adult stem cell population can fulfill two distinct functions: either help with digestion under normal conditions or take the lead on injury response. S
In this interview, Shianna Hines, the Senior Field Application Scientist for cannabis and hemp-related items at PerkinElmer, talks to AZoLifeSciences about testing cannabis for impurities and contaminants.
