Chocolate Flavored Iohexol

Chocolate-flavored iohexol is an orally administered formulation of iohexol, a nonionic, water-soluble iodinated contrast agent used to enhance radiographic visualization of the gastrointestinal tract. After ingestion, iodine atoms attenuate X-rays more strongly than surrounding soft tissues, increasing contrast between bowel contents and adjacent structures during computed tomography or other X-ray-based examinations; the chocolate flavor is intended to improve palatability and support completion of the prescribed dose. In medicine, this preparation helps clinicians assess bowel anatomy and suspected abnormalities while offering a more acceptable alternative to unflavored oral contrast when patient cooperation affects image quality.

Gustation

0 Views •

2019

Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors. Taste receptors are found on the surface of the tongue as well as on the soft palate, the pharynx, and the upper esophagus. On the tongue, taste receptors are contained...

Extraction of Biomarkers from Sediments - Accelerated Solvent Extraction

Source: Laboratory of Jeff Salacup - University of Massachusetts Amherst The distribution of a group of organic biomarkers called glycerol-dialkyl glycerol-tetraethers (GDGTs), produced by a suite of archaea and bacteria, were found in modern sediments to change in a predictable manner in response to air or water temperature1,2. Therefore, the distribution of these biomarkers in a sequence of sediments of known age can be used to reconstruct the evolution of air and/or water temperature on...

Determining the Role of Vitronectin in Bacterial Resistance to Bactericidal Activity of Human Serum

0 Views •

2025

This video demonstrates the role of vitronectin, a human serum glycoprotein, on bacterial resistance. Antibodies in the serum interact with bacterial surface proteins, activating complement proteins and forming the membrane attack complex, causing bacterial cell lysis. Vitronectin binding on bacterial membrane protein prevents the membrane attack complex formation, resulting in bacterial survival.
