Mometasone absorption in cultured airway epithelium
Background: Topical mometasone is frequently used as an intranasal spray, on drug-eluting stents, and compounded by specialty pharmacies as a sinus rinse. A typical sinus rinse contains 1.2 mg of mometasone dissolved in 240 mL of buffered saline and is flushed through the sinonasal cavity. The mometasone irrigation rapidly flows to the contralateral sinonasal cavity or the nasopharynx with a contact time on the order of 5 to 10 seconds. However, no information is available on the absorption rate of topical mometasone on the sinonasal surface. Methods: To determine the absorption characteristics of mometasone, we harvested nasal epithelium from 2 healthy donors and differentiated them into a mature ciliated epithelium on Millicell membranes. We applied mometasone to the apical surface for various time intervals and then rinsed off non-absorbed mometasone with phosphate-buffered saline. Millicell membranes with the adherent epithelial cells were then harvested and stored in guanidine hydrochloride for quantification using high-performance liquid chromatography–mass spectrometry. Results: Fifty percent of the maximal absorption occurred after an average of 38 minutes after application, and maximal absorption occurred after an average of 114 minutes. Conclusion: Our data provide an estimate for rates of absorption of mometasone applied to the sinonasal cavity and suggest that the absorption rates poorly match contact time during saline lavage
Serious Gaming in Manufacturing Education
The human capital for the European Factories of the Future is the key enabler to competing in high value manufacturing. Therefore, the education and training schemes for young talents, supported by new and rapidly developing ICT technologies, have to be flexible and adaptable to the future manufacturing needs. New approaches for managing knowledge and developing skills will be required so that the manufacturing decision making can be dispersed in the production level. In order for the best of European human capital to be a center of attention, the weak societal appeal of manufacturing has to be overcome as evidenced in the decline of student interest in Science, Technology, Engineering and Mathematics (STEM) subjects.
The aim of the paper is to focus on a sample of current offer of serious games in manufacturing education. Although manufacturing education have been using simulations in facilitating a better understanding of the theoretical concepts, the transition to using serious games is prone to mistakes. This paper presents the comparative analysis of three existing serious games in manufacturing education, assessing the game design and pedagogical underpinnings of the serious games. The result of the analysis has yielded a set of guidelines that supports the development of serious games in manufacturing education
