Adsorbents such as zeolite are widely used for volatile organic compounds (VOCs) removal, but a practical challenge is the decrease in VOCs removal efficiency under humid environment by competitive adsorption between water vapor and VOCs, which requires frequent regeneration using external energy. A combination of zeolites with photocatalytic materials can address this issue by oxidizing adsorbed VOCs from the zeolite surface to CO gas under light irradiation. Herein, the in situ formation of photocatalytic active defect-rich graphene is presented on a commercial zeolite surface (ZSM-5) when properly dealuminated ZSM-5 is exposed to an acetaldehyde/humid air mixture under visible light.

Background: Vascular smooth muscle cells (VSMCs) play an important role in regulating vessel diameter and blood pressure. Dysregulation of VSMC contraction contributes to the development of coronary and post-subarachnoid hemorrhagic (SAH) vasospasms. We investigated the molecular mechanisms by which valproic acid (VPA) inhibits Ras homolog family member A (RhoA)-mediated VSMC contraction in rat VSMCs and isolated aortas.

This study examined South Korean pregnant women's workplace experiences through Meleis' transition theory. Twenty participants engaged in online focus groups, discussing pregnancy, childbirth, prenatal care, and COVID-19 concerns. Content analysis revealed 15 themes reflecting transition theory's components.

Article Synopsis
  • Recent research shows that nitric oxide (NO) can trigger immunogenic cell death (ICD) in tumor cells by causing stress in the endoplasmic reticulum (ER) and destabilizing the mitochondrial membrane.
  • Because NO is unstable, the study introduces a new delivery method using a cell-penetrating polypeptide called poly(l-guanidine) (PLG), which can generate NO inside cells.
  • The helical structure of PLG not only penetrates cells but also creates reactive oxygen species (ROS) that lead to the production of NO, effectively inducing ICD through combined mechanisms involving ER stress and mitochondrial disruption.

Background: This study investigated the mediating effects of self-efficacy and social support on the relationship between stress and burnout among infection control nurses (ICNs) during an emerging infectious disease pandemic.

Methods: The study participants encompassed 210 ICNs with at least six months' experience in an infection control unit at a general hospital in South Korea during the COVID-19 pandemic. Data were analyzed using independent t-tests or one-way analysis of variance (ANOVA), while descriptive statistics were performed using SPSS/WIN 26.

Immunogenic cell death (ICD) holds the potential for in situ tumor vaccination while concurrently eradicating tumors and stimulating adaptive immunity. Most ICD inducers, however, elicit insufficient immune responses due to negative feedback against ICD biomarkers, limited infiltration of antitumoral immune cells, and the immunosuppressive tumor micro-environment (TME). Recent findings highlight the pivotal roles of stimulators of interferon gene (STING) activation, particularly in stimulating antigen-presenting cells (APCs) and TME reprogramming, addressing ICD limitations.

In addition to cellular damage, ischemia-reperfusion (IR) injury induces substantial damage to the mitochondria and endoplasmic reticulum. In this study, we sought to determine whether impaired mitochondrial function owing to IR could be restored by transplanting mitochondria into the heart under ex vivo IR states. Additionally, we aimed to provide preliminary results to inform therapeutic options for ischemic heart disease (IHD).

Since electroencephalogram (EEG) is a very small electrical signal from the brain, it is very vulnerable to external noise or motion artifact, making it difficult to measure. Therefore, despite the excellent convenience of dry electrodes, wet electrodes have been used. To solve this problem, self-adhesive and conductive composites using carbon nanotubes (CNTs) in adhesive polydimethylsiloxane (aPDMS), which can have the advantages of both dry and wet electrodes, have been developed by mixing them uniformly with methyl group-terminated PDMS.

Objectives: While the number of employed women has increased worldwide, they still have difficulties in practicing prenatal care at work. Previous studies have found that smartphone-based prenatal education has increased access to healthcare and contributed to improving pregnant women's health. The objective of this study was to evaluate the effectiveness of a mobile-based intervention-Self-care for Pregnant Women at Work (SPWW)-in enhancing the self-care practices of pregnant women who work.

Unlabelled: The purpose of the study was to investigate and compare the pregnancy stress, impact and fear of COVID-19 between working and non-working pregnant women in Korea. The influencing factors of pregnancy stress considering the pandemic situation were explored in each group. A descriptive cross-sectional study design was used in the study.

Background: Identifying point mutations in 23S rRNA closely associated with clarithromycin resistance can increase the eradication rate of Helicobacter pylori (H pylori). In this study, we verified the sensitivity, specificity, and reliability of a newly developed loop-mediated isothermal amplification (LAMP) assay kit to detect H pylori and 2143G and 2182C mutations in 23S rRNA.

Methods: LAMP assay to detect H pylori and a mutant strain with 2143G and 2182C was conducted with the Isopollo H pylori & ClaR kit.

Clarithromycin-based triple therapy is prescribed worldwide for Helicobacter pylori eradication. However, increases in the clarithromycin resistance of H pylori are thought to be responsible for eradication failure. Here, we studied whether point mutations in domain V of the 23S rRNA gene can affect H pylori eradication failure in a prospective, open-label, observational study.

In this paper, we present the design, fabrication, and performance evaluation of a polyimide-based flexible neural probe for the precise site stimulation and recording in the deep brain. The probe consists of five electrodes: one for stimulation, another for ground and the other three for recording electrodes. This probe is designed to be foldable, enabling easy insertion into the deep brain via temporary tungsten guide sticks.
