Effect of Zirconia and Alumina Fillers on the Microstructure and Mechanical Strength of Dental Glass Ionomer Cements

Open Dentistry Journal, 2016
Background: Glass-ionomer cements perform a protective effect on the dentin-pulp complex considering the F ions release and chemical bonding to the dental structures. On the other hand, those materials have poor physic-mechanical properties in comparison

Safety, tolerability, pharmacokinetics and pharmacodynamics of HSK31858, a novel oral dipeptidyl peptidase‐1 inhibitor, in healthy volunteers: An integrated phase 1, randomized, double‐blind, placebo‐controlled, single‐ and multiple‐ascending dose study

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Dipeptidyl peptidase‐1 (DPP‐1) inhibitors have been studied for the treatment of neutrophil‐mediated inflammatory diseases including bronchiectasis, bronchial asthma and cystic fibrosis. This study evaluated the pharmacokinetics, pharmacodynamics, safety and tolerability of DPP‐1 inhibitor HSK31858 in healthy Chinese volunteers.

Analytical and Pharmacological Characterization of 1‐(Furan‐2‐Carbonyl)‐LSD (1F‐LSD) and Comparison With 1‐(Thiophene‐2‐Carbonyl)‐LSD (1T‐LSD)

Drug Testing and Analysis, EarlyView.
The novel lysergamide 1‐(furan‐2‐carbonyl)‐LSD (1F‐LSD) was analytically characterized. 1F‐LSD showed LSD‐like activity in vivo similar to 1‐(thiophene‐2‐carbonyl)‐LSD (1T‐LSD) used for comparison. Administration studies in mice and LC–MS analysis revealed that 1F‐LSD served as a prodrug.

High‐Precision, Low‐Threshold Neuromodulation With Ultraflexible Electrode Arrays for Brain‐to‐Brain Interfaces

Exploration, EarlyView.
Traditional neuromodulation using rigid electrodes has been limited by low precision, large stimulating currents, and the risk of tissue damage. In this work, we developed a biocompatible flexible electrode array that allows for both neural recording of spike firings and high‐precision, low‐threshold stimulation for neuromodulation.
