Optimization of a micro-scale air-liquid-interface model of human proximal airway epithelium for moderate throughput drug screening for SARS-CoV-2.

Background: Many respiratory viruses attack the airway epithelium and cause a wide spectrum of diseases for which we have limited therapies. To date, a few primary human stem cell-based models of the proximal airway have been reported for drug discovery but scaling them up to a higher throughput platform remains a significant challenge. As a result, most of the drug screening assays for respiratory viruses are performed on commercial cell line-based 2D cultures that provide limited translational ability.

Outcomes of surveyed monolithic CAD/CAM zirconia crowns for removable partial denture abutments: A 7-year clinical study.

Purpose: This retrospective clinical study aimed to evaluate the clinical outcomes of surveyed monolithic computer-aided design and computer-aided manufacturing (CAD/CAM) zirconia crowns for abutment teeth in removable partial dentures (RPDs).

Methods: Patients who received monolithic surveyed zirconia crowns were clinically examined. The crowns were examined according to the modified United States Public Health Service criteria, and Kaplan-Meier survival was determined.

Nanoarchitectonics of a Skin-Like Polymeric Hydrogel with High Anti-Swelling and Self-Adhesion Performance for Underwater Communication.

Hydrogels are flexible materials characterized by a 3D network structure, which possess high water content and adjustable physicochemical properties. They have found widespread applications in tissue engineering, electronic skin, drug delivery, flexible sensors, and photothermal therapy. However, hydrogel networks often exhibit swelling behavior in aqueous environments, which can result in structural degradation and a loss of gel performance.

Phloretin-nanospanlastics for targeting the Akt/PI3K signaling pathways in dimethylhydrazine-induced colon cancer in mice.

Objectives: Colorectal cancer is the third most common cancer worldwide, accounting for approximately 10 % of all cancer cases. It is also the second leading cause of cancer-related deaths globally. Phloretin is a natural compound found in apples and other fruits.
