Incorporation of Nitroprusside on Silica Nanoparticles-A Strategy for Safer Use of This NO Donor in Therapy.

Silica-based nanoparticles have been developed as powerful platforms for drug delivery and might also prevent undesired side effects of drugs. Here, a fast method to synthesize positively charged mesoporous silica nanoparticles (ζ = 20 ± 0.5 mV, surface area = 678 m g, and 2.

Tablet-Based Hearing Screening Test.

Introduction: Hearing loss (HL) affects people worldwide, many of whom are children. Especially in developing countries, epidemiological data on the prevalence of HL are insufficient to implement effective health promotion programs. In this preliminary study with young adults, we describe and validate a tablet-based hearing screening test developed for interactive remote hearing screening and compare the performance of an audiometry screening tablet application with conventional audiometry.
