Study on the Antibacterial Properties and Optical Characteristics of Clear Orthodontic Aligners Coated With Zinc Oxide and Magnesium Oxide Nanoparticles.
Orthod Craniofac Res
January 2025
Dental Materials Research Center, Health Research Institute, Babol University of Medical Sciences, Babol, I.R.Iran.
Objectives: This study aimed to evaluate and compare the antibacterial properties and optical characteristics of clear orthodontic aligners coated with zinc oxide (ZnO) and magnesium oxide (MgO) nanoparticles.
Materials And Methods: In this experimental laboratory study, polyethylene terephthalate glycol (PETG) aligner samples were coated with nanoparticles of ZnO, MgO and a combination of both (ZnO + MgO). The surface coatings were analysed before and after stability testing using field emission scanning electron microscopy (FESEM).
Behavioral and Psychological Symptoms (BPSD) in Alzheimer's Disease (AD): Development and Treatment.

Behavioral and psychological symptoms of dementia (BPSD), such as agitation, apathy, and psychosis, are highly prevalent and have a significant impact on patients and their care partners. The neurobiology of BPSD involves a complex interplay of structural brain changes and alterations in the neurotransmitter system. Various genetic and plasma biomarkers have also been studied.

Department of Blood Transfusion, First Affiliated Hospital, Third Military Medical University (Army Medical University), Chongqing, People's Republic of China.
Background: Platelet concentrates play an important role in clinical treatment such as platelet function disorders and thrombocytopenia. In the process of preparation and storage of platelets, centrifugation, leukofiltration, and agitation will cause morphological changes and impaired function of platelets, which is associated with the increase of platelet transfusion refractoriness, and named as platelet storage lesion (PSL).
Method: This paper proposes three major operations (centrifugation, agitation, and leukofiltration) that platelets experience during the preparation and storage process, to explore the effect of physical cues on PSL.
Effects of Dexmedetomidine as an Adjuvant in Preoperative Ultrasound-Guided Internal Branch of Superior Laryngeal Nerve Block on Postoperative Sore Throat and Hemodynamics in Patients With Double-Lumen Endotracheal Intubation: A Randomized Controlled Trial.

Department of Anesthesiology, The Second Hospital, Cheeloo College of Medicine, Shandong University, Jinan, 250033, People's Republic of China.
Background: Postoperative sore throat (POST) is a significant adverse effect after endotracheal intubation, especially with double-lumen endotracheal tubes (DLTs). Ultrasound-guided internal branch of the superior laryngeal nerve block (US-guided iSLNB) presents a potential intervention for POST. In this first randomized controlled trial to date, we aimed to investigate the effects of US-guided iSLNB, with or without perineural dexmedetomidine, on the incidence and severity of POST following DLTs.

Modelling the prodrome to severe mental disorders (SMD), including unipolar mood disorders (UMD), bipolar mood disorders (BMD) and psychotic disorders (PSY), should consider both the evolution and interactions of symptoms and substance use (prodromal features) over time. Temporal network analysis can detect causal dependence between and within prodromal features by representing prodromal features as nodes, with their connections (edges) indicating the likelihood of one feature preceding the other. In SMD, node centrality could reveal insights into important prodromal features and potential intervention targets.
