Effect of Stool Sampling on a Routine Clinical Method for the Quantification of Six Short Chain Fatty Acids in Stool Using Gas Chromatography-Mass Spectrometry.

Short chain fatty acids (SCFAs) are primarily produced in the caecum and proximal colon via the bacterial fermentation of undigested carbohydrates that have avoided digestion in the small intestine. Increasing evidence supports the critical role that SCFAs play in health and homeostasis. Microbial SCFAs, namely butyric acid, serve as a principal energy source for colonocytes, and their production is essential for gut integrity.

High performance liquid chromatography-tandem mass spectrometry quantification of tryptophan metabolites in human serum and stool - Application to clinical cohorts in Inflammatory Bowel Diseases.

Tryptophan, an essential amino acid, and its metabolites are involved in many physiological processes including neuronal functions, immune system, and gut homeostasis. Alterations to tryptophan metabolism are associated with various pathologies such as neurologic, psychiatric disorders, inflammatory bowel diseases (IBD), metabolic disorders, and cancer. It is consequently critical to develop a reliable, quantitative method for the analysis of tryptophan and its downstream metabolites from the kynurenine, serotonin, and indoles pathways.

Effect of PET Size, Content and Mixing Process on the Rheological Characteristics of Flexible Pavement.

The performance of asphalt binder reinforced with waste plastic polyethylene terephthalate (PET) was investigated. Penetration, ductility, softening point, and rotational viscosity tests were conducted to check the performance of the PET-reinforced pavement. The rheological properties of the binder were determined using amplitude sweep and frequency sweep tests and performance grade (PG) measurements of aged and unaged specimens.

Diaphragmatic Hernia with Gastric Volvulus and Complete Gastric Outlet Obstruction.

A combination of Cytoreductive surgery (CRS) along with hyperthermic intraperitoneal chemotherapy (HIPEC) considers a crucial approach in treating designated patients with alimentary and gynecological malignancies with the involvement of the peritoneal cavity. The foremost frequent surgical complications are leakage, digestive perforations, fistulas, intestinal obstruction, abscess, and peripancreatitis. This report presents a case of a patient with a late acquired herniation of guts through the diaphragm after CRS and HIPEC that were already done 6 months back.
