Background: Inflammation in cystic fibrosis (CF) airways is difficult to treat with well-established regimens often including azithromycin (AZ) as an immunomodulatory drug. As AZ has been reported to require CF transmembrane conductance regulator (CFTR) to be able to reduce interleukin (IL)-8 and given the emergence of highly effective CFTR "triple" modulator therapy (elexacaftor/tezacaftor/ivacaftor; ETI), the aim of this study was to investigate the effect of AZ and ETI, singly and in combination, on ion channel activity and to assess the potential anti-inflammatory effects.
Methods: Electrophysiological assessment of ETI and AZ was performed on three-dimensional cultures of primary CF human bronchial epithelial (HBE) cells using a Multi Trans-Epithelial Current Clamp.
Self-reported height and weight is widely used to calculate Body Mass Index (BMI) and yet little is known about factors that affect accuracy. This study investigated the motivational characteristics-narcissism and social desirability-that influence the accuracy of self-reported weight and how they interact with accountability (telling participants that their weight will be verified). A two-way between-subjects design was used (accountable vs not accountable) with motivational moderators (narcissism and social desirability).

In addition to functioning as a protective barrier, the plasma membrane plays dynamic roles in a wide range of functions needed for virulence including nutrient uptake, cell wall synthesis, morphogenesis, resistance to stress, and invasive hyphal growth. Screening a collection of mutants identified an understudied gene that is important for invasive hyphal growth, which we have termed (Cell Wall Regulatory kinase).

Guided tissue regeneration techniques, particularly barrier membranes, enable local regeneration by providing an isolated, protected compartment for osseous wound healing while excluding epithelial tissue. Here, this study reports on a thermosensitive periodontal membrane (TSPM) technology designed to overcome the mechanical limitations of current membranes through a semi-interpenetrating network of high molecular weight poly(L-lactic acid) (PLLA) and in situ-polymerized mesh of poly(ε-caprolactone)diacrylate (PCL-DA), and poly lactide-co-glycolide diacrylate (PLGA-DA).

Methods: The aim of this project was to evaluate the feasibility and effectiveness of a residency program for licensed RTs with < 1 y of experience post graduation. The approach to improve new graduate transition to practice included a streamlined clinical-based orientation, didactic learning, evidence-based practice plan, and incorporated simulation.
