Static in vitro digestion model adapted to the general older adult population: an INFOGEST international consensus
PublicationUnderstanding the mechanisms of food digestion is of paramount importance to determine the effect foods have on human health. Significant knowledge on the fate of food during digestion has been generated in healthy adults due to the development of physiologically-relevant in vitro digestion models. However, it appears that the performance of the oro-gastrointestinal tract is affected by ageing and that a model simulating the digestive...

Rengel Cane Sia Doctoral Candidate
PeopleI’m Rengel, born and raised in the Philippines. As an undergraduate I did kinetic modeling on Copper-catalyzed atom transfer radical addition (ATRA). Then I was inspired to do both theoretical and experimental studies, which led me to propose my master’s thesis on Synthesis, Computational, Electrochemical, and Photoconductivity Studies on Naphthalene and its derivatives. This led to a master’s degree in Chemistry in the Mindanao...

Cannabinoid CB1 antagonists and dopamine antagonists produce different effects on a task involving response allocation and effort-related choice in food-seeking behavior
PublicationW przeprowadzonych badaniach iniekcja antagonistów dopaminy (DA) szczurom powoduje znaczny spadek użycia siły przez zwierzęta w poszukiwaniu żywności i jednoczesny wzrost spożycia jedzenia laboratoryjnego. Przeciwnie, iniekcja antagonisty AM4113 lub odwrotnego agonisty AM251 receptora CB1 powoduje zmniejszenie ilości jedzenia granulek, ale nie wpływa na zwiększenie konsumpcji jedzenia laboratoryjnego. Efekty wywierane na zwierzęta...

The novel cannabinoid CB1 receptor neutral antagonist AM4113 suppresses ood intake and food-reinforced behavior but does not induce signs of nausea in rats
PublicationPrzeprowadzone badania biochemiczne wykazują, że związek AM4113 wiąże się z receptorem kanabinoidowym CB1, ale nie wykazuje właściwości odwrotnego agonisty (między innymi nie wpływa na powstawanie cyklicznego AMP). W testach na swobodne przemieszczanie się szczurów i znieczulenie związek AM4113 osłabia wpływ agonisty AM411 na receptor CB1. AM4113 wpływa na zachowanie szczurów związane z karmieniem oraz powoduje spadek łaknienia...

Which casein in sodium caseinate is most resistant to in vitro digestion? Effect of emulsification and enzymatic structuring
PublicationWe investigated the resistance of individual constituent casein epitopes (αS1-, αS2-, β- and κ-CN) in food-grademilk protein sodium caseinate (NaCN) to simulated human gastro-duodenal digestion. The influence of NaCNadsorption to the surface of oil-in-water emulsion droplets and the effect of crosslinking of the protein withenzyme transglutaminase (TG) on the proteolysis were studied by indirect ELISA. TG crosslinking renderedfragments...

Proteolysis of whey protein isolates in nanoemulsion systems: impact of nanoemulsification and additional synthetic emulsifiers
PublicationNanoemulsions are currently of interest in the functional food sector because their small droplet size (100–500 nm) provides a number of potential advantages over conventional emulsions. This study concerned the behavior of nanoemulsions stabilized with whey proteins and two synthetic emulsifiers (Tween 80 and Croduret), and exposed to conditions simulating the human upper gastrointestinal tract. In particular, the effect of synthetic...

Isothiocyanates may chemically detoxify mutagenic amines formed in heat processed meat
PublicationMeat consumption represents a dietary risk factor increasing the incidence of common cancers, probably due to carcinogenic amines (HAAs) formed upon meat heating. Interestingly, cancers whose incidence is increased by meat consumption, are decreased in populations consuming brassica vegetables regularly. This inverse correlation is attributed to brassica anticarcinogenic components, especially isothiocyanates (ITCs) that stimulate...
