Effects of structural variation in electrospray systems on spray characteristics.

Electrospraying is a method of atomizing fluids using a high voltage potential difference. Since the atomization of electrostatic atomization does not directly charge the nozzle but only uses the potential difference, various equipment structures are possible. In the case of this study, 12 different equipment structures of nozzle, ring electrode, and substrate were configured, and data on atomization characteristics of electrospray, such as spray modes applied voltage, coating area, coating current, spray velocity, and factors used in industrial processes, were verified.

Accuracy of Rapid Antigen Screening Tests for SARS-CoV-2 Infection at Correctional Facilities in Korea: March - May 2022.

Background: The number of confirmed cases of individuals with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection increased rapidly due to the Omicron variant. Correctional facilities are vulnerable to infectious diseases, and they introduced rapid antigen tests (RATs) to allow for early detection and rapid response. We aimed to evaluate the diagnostic performance and usefulness of SARS-CoV-2 RATs in newly incarcerated people.

Comparison of vital sign stability and cost effectiveness between midazolam and dexmedetomidine during third molar extraction under intravenous sedation.

Objectives: To compare the vital sign stability and cost of two commonly used sedatives, midazolam (MDZ) and dexmedetomidine (DEX). Patients and.

Methods: This retrospective study targeted patients who underwent mandibular third molar extractions under intravenous sedation using MDZ or DEX.

Screw-and-cement-retained prosthesis versus cement-retained prosthesis: Which is more appropriate for the upper premolar area?

Background/purpose: The narrow alveolar ridge in the maxillary premolars area limits the angle of implant placement and the shape of the prosthesis. The aim of this study was to evaluate which implant prosthesis, screw-and-cement-retained prosthesis (SCRP) or cement-retained prosthesis (CRP), was more suitable for the maxillary premolar area.

Materials And Methods: We conducted virtual implantation on 58 implant images from 47 patients obtained using cone beam computed tomography (CBCT).

White Matter Microstructural Alterations in Newly Diagnosed Parkinson's Disease: A Whole-Brain Analysis Using dMRI.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by cardinal motor symptoms and other non-motor symptoms. Studies have investigated various brain areas in PD by detecting white matter alterations using diffusion magnetic resonance imaging processing techniques, which can produce diffusion metrics such as fractional anisotropy and quantitative anisotropy. In this study, we compared the quantitative anisotropy of whole brain regions throughout the subcortical and cortical areas between newly diagnosed PD patients and healthy controls.

Effect of IRT5 probiotics on dry eye in the experimental dry eye mouse model.

Objective: To investigate the clinical effects of IRT5 probiotics in the environmental dry eye model.

Methods: Eight week old male C57BL/6 mice were randomly divided into two groups; control group (n = 16) received oral gavage of 300 μL phosphate-buffered saline (PBS) alone once daily, IRT5 group (n = 9) received oral gavage of 1 x 109 CFU IRT5 probiotics powder in 300 μL PBS once daily, both groups for 11 to 12 days. Simultaneously, all mice underwent dry eye induction.
