Cholecystokinin: Clinical aspects of the new biology

open access: yesJournal of Internal Medicine, EarlyView.
Abstract Cholecystokinin (CCK) is a classic gut hormone that has been known for almost a century to regulate gallbladder emptying, pancreatic enzyme secretion, and gastrointestinal motor activity. In 1968, the CCK structure was identified by Viktor Mutt and Erik Jorpes from porcine gut extracts as a peptide of 33 amino acid residues.

Impact of various aging treatments on the microhardness and surface roughness of CAD‐CAM monolithic restorative materials

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose Dental ceramics deteriorate as a result of thermal aging and exposure to acidic solutions, which change their microhardness and surface roughness. This study assessed the resistance of several computer‐aided design and computer‐aided manufacturing (CAD‐CAM) restorative dental materials in terms of surface roughness and microhardness ...

Validation of clinically related aging models based on enamel wear

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose Physiological and erosive wear reported in clinical studies were reviewed, and in vitro aging models were developed to simulate and compare the effect of aging on human teeth with the review data obtained from clinical studies. Methods A review of clinical studies and randomized clinical trials that quantify enamel wear was performed ...
