Short-chain fatty acids in the saliva of patients with gastroesophageal reflux disease.

Gastroesophageal reflux disease (GERD) is a condition characterized by persistent symptoms and complications resulting from reflux of gastric contents into the esophagus. Short-chain fatty acids (SCFAs) are fermentation products of dietary fibres by the gut microbiota and are often studied for their anti-inflammatory and anticancer effects. The presence of SCFAs in the upper gastrointestinal tract, including in patients with GERD, has not been previously studied.

Simultaneous detection of melatonin and six metabolites of L-tryptophan pathway in rat gastric mucosa.

Melatonin (N-acetyl-5-methoxytryptamine) is an indoleamine synthesized in vertebrates mainly in the pineal gland, and is known to be involved mainly in thermoregulation and control of the circadian rhythm. That indoleamine can affect the auto-, para- and endocrine pathways, regulating body functions and affecting the metabolism of animals and humans. In addition to the pineal gland, melatonin can be synthesized in many extra-pineal tissues, mainly in the gastrointestinal tract.

Effect of Supercritical Extract from Black Poplar and Basket Willow on the Quality of Natural and Probiotic Drinkable Yogurt.

Yogurt is a fermented milk drink produced by , ssp. , or , which can be enriched with polyphenolic compounds to enhance its antioxidant properties. Supercritical (scCO/HO) extracts obtained from the mixture of bark and wood of black poplar () and basket willow () are the source of bioactive compounds.

Mortality Following Infection in Europe: A Retrospective Multicenter Case-Control Study.

We aimed to describe the clinical presentation, treatment, outcome and report on factors associated with mortality over a 90-day period in infection (CDI). Descriptive, univariate, and multivariate regression analyses were performed on data collected in a retrospective case-control study conducted in nine hospitals from seven European countries. A total of 624 patients were included, of which 415 were deceased (cases) and 209 were still alive 90 days after a CDI diagnosis (controls).
