Efficacy of Orthognathic Surgery in OSAS Patients: A Systematic Review and Meta-Analysis.

Background: Obstructive sleep apnea syndrome (OSAS) is a prevalent condition characterised by repeated episodes of partial or complete obstruction of the upper airway during sleep, leading to disrupted sleep and associated morbidities. Orthognathic surgery (OGS) has been proposed as a treatment option for OSAS, aimed at anatomically repositioning the maxillofacial structures to alleviate airway obstruction. This systematic review and meta-analysis aimed to evaluate the efficacy of OGS in reducing apnea-hypopnea index (AHI) and Epworth Sleepiness Scale (ESS) scores among OSAS patients.

This study aimed to identify potent and safe inhibitors of KAT-II using computational and in vitro approaches.

Facilitation of Tumor Stroma-Targeted Therapy: Model Difficulty and Co-Culture Organoid Method.

Tumors, as intricate ecosystems, comprise oncocytes and the highly dynamic tumor stroma.

From Waste to Innovation: A Circular Economy Approach for Tissue Engineering by Transforming Human Bone Waste into Novel Collagen Membranes.

The aim of the circular economy is to treat waste as a valuable raw material, reintegrating it into the industrial economy and extending the lifecycle of subsequent products. Efforts to reduce the production of hard-to-recycle waste are becoming increasingly important to manufacturers, not only of consumer goods but also of specialized items that are difficult to manufacture, such as medical supplies, which have now become a priority for the European Union. The purpose of the study is to manufacture a novel human-purified type I collagen membrane from bone remnants typically discarded during the processing of cortico-cancellous bones in tissue banks and to evaluate its mechanical properties and effectiveness in regenerating bone-critical mandibular defects in rabbits.

Lactoferrin Modulates Radiation Response Under Hypoxic Conditions, Possibly Through the Regulation of ROS Production in a Cell Type-Specific Manner.

Lactoferrin (LF) is an iron-binding glycoprotein of the transferrin family and has been suggested to have a variety of biological functions, including anticancer activity. However, the effects of LF and its mechanisms in anticancer therapies, especially in radiotherapy against cancer cells under hypoxic conditions, are not well-determined. In this study, we focused on the molecular mechanisms of LF functions in cells under hypoxic conditions.
