Objective: This study assesses the impact of initial messaging strategies on medication behavior in newly diagnosed hypertension patients in a hypothetical context. Applying Construal Level Theory, this study evaluated which message type-low construal (focused on how, feasibility, and concrete) or high construal (focused on why, desirability, and abstract)-is more effective.

Methods: An online quasi-experiment was performed with 1200 participants without hypertension aged 30-60.

Desalination techniques using the photothermal effect hold significant potential for producing fresh water from saline or polluted sources due to their low energy consumption. In the case of commercialized carbon materials are related to heat loss resulting from high thermal conductivity, and metal particles still have trouble in commercialization or cost-effectiveness. This is because a photothermal desalination evaporator must simultaneously exhibit high water evaporation performance, excellent energy conversion efficiency, sufficient hydrophilicity, and low heat loss.

Purpose: This study aimed to identify the association between coronavirus disease 2019 (COVID-19) transmission levels and undergoing glycated hemoglobin (HbA1c) test and complication screenings among patients with diabetes mellitus.

Materials And Methods: We included a total of 3601 diabetes patients' data from the 2020 Korean Community Health Survey to analyze the extent of the HbA1c testing and fundus examination, and 3592 diabetes patients' data to analyze kidney disease screening. COVID-19 transmission levels were classified into low transmission (Busan, Gwangju, Daejeon, Ulsan, and Sejong) and high transmission (Daegu, where the first large outbreak of COVID-19 occurred in Korea).

Article Synopsis
  • * Researchers produced FopA antigen using a baculovirus system and generated specific antibodies by immunizing mice, then screened these using hybridoma and phage display technologies.
  • * Two monoclonal antibodies (6B12 and 3C1) were successfully developed, leading to a sensitive sandwich ELISA for tularemia diagnosis with low detection limits, providing a more effective alternative to traditional tests.

Sulfate radical (SO)-based advanced oxidation processes (SR-AOPs) have been studied to date by utilizing metal-organic frameworks as efficient catalysts to generate sulfate radicals by peroxymonosulfate (PMS) activation in water purification. It is important to select high-performance and reliable catalysts for efficient water remediation, and separation and recovery of catalysts are essential in the practical application of MOFs. Herein, we adapted thermally curable, shape-controllable, and cost-effective agarose (AG) as a smart matrix and ZIF-67, as a powerful catalyst to prepare nanoarchitectured aerogel (Z67@AG).

Biological weapons, primarily dispersed as aerosols, can spread not only to the targeted area but also to adjacent regions following the movement of air driven by wind. Thus, there is a growing demand for toxin analysis because biological weapons are among the most influential and destructive. Specifically, such a technique should be hand-held, rapid, and easy to use because current methods require more time and well-trained personnel.

The chemical/physical properties and reliable performance of nanoporous materials are strongly influenced by the particle size and corresponding distribution. Among many types of MOFs, ZIF-8, is still widely used and many studies have been conducted to control the particle size and uniformity of ZIF-8 using surfactants and organic solvents. However, the use of surfactants and organic solvents process is expensive and may cause environmental pollution.

Nanocellulose-based aerogels have been considered as one of the ideal candidates for CO capture in practical applications owing to their lightweight and porous properties. Additionally, various adsorbents with amine groups have been widely used as effective CO capture and storage strategies. Herein, amino-functionalized aerogels were prepared by sol-gel and freeze-drying methods using two typical nanocelluloses (cellulose nanofibrils (CNFs) and cellulose nanocrystals (CNCs)) as substrates.

Objective: We aimed to compare the adaptive immune response in individuals with or without prior SARS-CoV-2 infections following the administration of mRNA-based COVID-19 vaccines.

Methods: A total of 54 participants with ages ranging from 37 to 56 years old, consisting of 23 individuals without a history of SARS-CoV-2 infection (uninfected group) and 31 individuals with prior infection of SARS-CoV-2 (infected group) who have received two doses of mRNA SARS-CoV-2 vaccines were enrolled in this study. We measured the IFN-γ level upon administration of BNT162b2 (PF) or mRNA-1273 (MO) by QuantiFERON SARS-CoV-2.

Background: The reliability and validity of the anxiety subscale of the Hospital Anxiety and Depression Scale for Koreans (K-HADS-A) has not been studied in Korean surgical patients. This study aimed to validate the usefulness of K-HADS-A for measuring preoperative anxiety in Korean surgical patients. Additionally, the effect of preoperative anxiety on postoperative quality of recovery was evaluated.

In this study, we evaluated the effectiveness of the bivalent mRNA COVID-19 vaccines against the Omicron variant in individuals with or without prior SARS-CoV-2 infection history. We assessed the SARS-CoV-2-specific neutralizing antibody in serum samples by surrogate virus neutralizing assay (sVNT) and determined the serum's neutralizing capacity against the Omicron BA.5 by a plaque reduction neutralizing test (PRNT50).

Article Synopsis
  • A study compared the mechanical characteristics of four different fixation methods for treating fractures in the pelvis of elderly patients using composite hemipelvic models.
  • The fixation methods included an anatomical suprapectineal QLS plate and various types of suprapectineal reconstruction plates, and were assessed for structural stiffness and fragment displacement.
  • Results showed that the QLS plate offered comparable or superior stability to other methods, especially in certain regions, but suggested that further modifications are necessary for optimal outcomes.

Herein, we report an electrocatalytic hydrofluorination of aryl-substituted alkenes with a nucleophilic fluorine source. The merger of palladium catalysis with electrooxidation enables the transformation of various substrates ranging from styrenes to more challenging α,β-unsaturated carbonyl derivatives to the corresponding benzylic fluorides. This method can also be applied to the late-stage modification of pharmaceutical derivatives.
