Morbidity of the Free Fibular Flap in Reconstructive Surgery.

Background: Our study evaluated long-term morbidities in patients and compared subjective morbidities to those measurable objectively.

Methods: Patients completed a questionnaire regarding long-term morbidity, filled out the Pain Sensitivity Questionnaire by Ruscheweyh et al. and were examined physically.

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.

The effect of mandibular advancement on pharyngeal airway space in patients with oral squamous cell carcinoma: A monocentric prospective study with computed tomography.

Objectives: The presented study aimed to evaluate the effect of mandibular protrusion with a temporarily applied mandibular advancement device (MAD) on the posterior airway space and to determine a reliable metric constant based on a three-dimensional computed tomography (CT) evaluation.

Materials And Methods: The study population consisted of patients with oral squamous cell carcinoma who were treated at least six months prior to the follow-up CT in supine position. Each patient received an individually adjusted MAD that was temporarily applied with three different protrusion distances (P = 0 mm, P = 4 mm, and P = 8 mm) during follow-up CT.

Synthesis and Structure-Activity Relationship of Covalent Inhibitors of SARS-CoV-2 Papain-Like Protease with Antiviral Potency.

The papain-like protease (PLpro) is a highly conserved domain encoded by the coronavirus (CoV) genome and it plays an essential role in the replication and maturation of the virus in addition to weakening host immune response. Due to the virus's reliance on PLpro for survival and propagation, small-molecule inhibitors of PLpro serve as an attractive model for direct-acting antiviral therapeutic agents against SARS-CoV-2. Building upon existing work aimed at designing covalent inhibitors against PLpro, we report the synthesis and structure-activity relationship of analogs based on the known covalent inhibitor 1 (Sanders, et al.
