Overcoming obstacles to mammography screening: Examining the role of offline healthcare barriers and online patient-provider communication.

Barriers to accessing offline healthcare may discourage patients from undergoing mammography screening. Online patient-provider communication (OPPC) offers a supplementary health resource that can complement traditional medical encounters and facilitate mammography screening. This study examines how offline healthcare barriers influence mammography screening, taking into account OPPC as an independent variable and cancer fatalism and patient activation as two mediators.

How does patient-centered communication work? Trend analysis of mediation through cancer worry and health self-efficacy, 2011-2020.

This study proposed and tested the cross-sectional effects of patient-centered communication (PCC) on cancer screening behaviors via an affective-cognitive sequential chain of mediation through cancer worry and health self-efficacy. Cross-sectional data were analyzed from four iterations of the Health Information National Trends Survey (2011, 2014, 2017, and 2020). The results found that lowered cancer worry following PCC does not show a cross-sectional positive effect in promoting cancer screening behaviors, while enhanced health self-efficacy as a subsequent state is a facilitator of screening behaviors.

Social media and partnership jointly alleviate caregivers' psychological distress: exploring the effects of online and offline connectedness.

Background: The prevalence of caregiving in the United States has increased from 16.6% to 19.2% during the period between 2015 and 2020.

Longitudinal relationship between social media and e-cigarette use among adolescents: the roles of internalizing problems and academic performance.

Background: Prior research has investigated the influence of social media on e-cigarette use among adolescents, predominantly through the display of e-cigarette content and advertisements. However, the psychological mechanism underlying this relationship remains underexplored. This study aims to address the mediating effect of youths internalizing problems and elucidate the moderating effect of academic performance from a longitudinal perspective.

Clonal integration can promote the growth and spread of Alternanthera philoxeroides in cadmium-contaminated environments.

Clonal plants are able to support the growth of their ramets in stressful environments via clonal integration between the ramets. However, it remains unclear whether the developmental status of stressed ramets affects the role of clonal integration. Here, we explored the effects of clonal integration at both the ramet level and the whole clonal fragment level when the apical ramets (younger) and basal ramets (older) were subjected to different concentrations of cadmium contamination.

The Plant Invader Benefits from Clonal Integration More than Its Native Co-Genus in Response to Patch Contrast.

Different connected parts of clonal plants often grow in different patches and the resource contrast between patches has an important effect on the material transfer between the connected ramets. However, it is unclear whether the effect of clonal integration differs between the invasive clonal plant and the related native species in response to patch contrast. To explore this, we grew the clonal fragment pairs of plant invader and its co-genus native species under high contrast, low contrast, and no contrast (control) nutrient patch environments, respectively, and with stolon connections either severed or kept intact.

Distributed Acoustic Sensing Based on Microtremor Survey Method for Near-Surface Active Faults Exploration: A Case Study in Datong Basin, China.

Active fault detection has an important significance for seismic disaster prevention and mitigation in urban areas. The high-density station arrays have the potential to provide a microtremor survey solution for shallow seismic investigations. However, the resolution limitation of the nodal seismometer and small-scale lateral velocity being inhomogeneous hinder their application in near-surface active fault exploration.

A solution-processed n-type conducting polymer with ultrahigh conductivity.

Conducting polymers (CPs) with high conductivity and solution processability have made great advances since the pioneering work on doped polyacetylene, thus creating the new field of 'organic synthetic metals,. Various high-performance CPs have been realized, which enable the applications of several organic electronic devices. Nevertheless, most CPs exhibit hole-dominant (p-type) transport behaviour, whereas the development of n-type analogues lags far behind and only a few exhibit metallic state, typically limited by low doping efficiency and ambient instability.

Interrater reliability estimators tested against true interrater reliabilities.

Background: Interrater reliability, aka intercoder reliability, is defined as true agreement between raters, aka coders, without chance agreement. It is used across many disciplines including medical and health research to measure the quality of ratings, coding, diagnoses, or other observations and judgements. While numerous indices of interrater reliability are available, experts disagree on which ones are legitimate or more appropriate.

Associations Between COVID-19 Information Acquisition and Vaccination Intention: The Roles of Anticipated Regret and Collective Responsibility.

While public health communication has been suggested to be a key for improving acceptance of COVID-19 vaccination, this study tested mediation pathways through which three types of vaccine information acquisition, i.e. seeking, scanning, and discussing, affect COVID-19 vaccination intention.

Isolation and immune activity of a new acidic Cordyceps militaris exopolysaccharide.

A new type of acidic exopolysaccharide (AESP-II) was extracted and separated from the fermentation broth of Cordyceps militaris (C. militaris), which was further purified to elucidate its structural characteristics and immunological activity. AESP-II was confirmed to be an acidic pyranose with a molecular weight of 61.

The construction of an artificial light-harvesting system with two-step sequential energy transfer based on supramolecular polymers.

An artificial light-harvesting system with two-step sequential energy transfer was constructed in aqueous media based on cyano-substituted -phenylenevinylene derivative (PPTA) and bis-(-sulfonatocalix[4]arenes) (BSC4) supramolecular polymers formed through host-guest interactions, in which two different fluorescent dyes, eosin Y (EY) and sulforhodamine (SR101), were employed as energy acceptors. The obtained artificial light-harvesting system can achieve an efficient two-step energy transfer process from PPTA-BSC4 to EY and then to SR101 with high energy-transfer efficiencies of up to 36.6% and 40.

Background: Mitochondrial transcription elongation factor (TEFM) is an essential molecule that regulates the replication-transcription switch of mitochondrial DNA. TEFM modulates both transcription elongation and RNA processing in mitochondria. The purpose of the present study was to determine the association of TEFM with tumor progression and prognosis in hepatocellular carcinoma (HCC) patients.

TGF‑β1‑induced epithelial‑mesenchymal transition increases fatty acid oxidation and OXPHOS activity via the p‑AMPK pathway in breast cancer cells.

Breast cancer is the most common malignancy in women, and metastasis is the leading cause of death in breast cancer patients. Previous studies have shown that epithelial‑mesenchymal transition (EMT) is involved in the metastasis of breast cancer, but the metabolic reprogramming and regulation mechanisms involved in the EMT process are still unclear. In the present study, we successfully constructed an EMT cell model induced by transforming growth factor β1 (TGF‑β1) treatment of MCF‑7 cells at different times.
