Los rayos X se han utilizado durante décadas para estudiar la estructura de los materiales cristalinos. Sin embargo, en las técnicas de los últimos años se han ideado que, en combinación con la disponibilidad de intensos haces colimados de fuentes de radiación, han transformado los rayos X en una versátil y potente herramienta para el…
DetailsEffect of Sequence and Structural Properties on 14-Helical ?-Peptide Activity against Candida albicans Planktonic Cells and Biofilms Abstract ?-Peptides (? -amino acid oligomers) that mimic the amphiphilic, helical, and cationic properties of natural antimicrobial peptides have previously been shown to display antifungal activity against planktonic Candida albicans cells. ?-Peptides offer several advantages over conventional peptides…

DetailsHydroxypropyl methylcellulose (HPMC) is a biodegradable polymer which has been used as an ophthalmic lubricant and controlled-delivery component in oral medicaments. Biodegradable polymers are recommended to form films in which an active pharmaceutical ingredient (API) is suspended, since it gels when the temperature is increased. In this work, the effect of concentration and type of…
