Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations

Advanced Functional Materials, EarlyView.
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.

Calculation of the Sun exposure time for the synthesis of vitamin D in Urcuquí, Ecuador [PDF]

Proceeding of Abstracts of IWBBIO, Francisco Ortu\~no Guzm\'an, Ignacio Rojas Ru\'iz (Comp.), ISBN: 978-84-16929-58-0 (2017), 27, 2017
The synthesis of vitamin D is strongly linked to the availability of solar energy. For a long time, it was clear that using the erythemal irradiances is a good choice to calculate the exposure time. Several authors argue that this method of minimum exposure time overestimates the calculation of the solar irradiance of vitamin D.
