This study examines attenuated risk responses among individuals who do not adhere to preventive COVID-19 measures (e.g., antimaskers).

Ultrasound-guided intra-articular corticosteroid injection in a patient with manubriosternal joint involvement of ankylosing spondylitis: A case report.

Background: Manubriosternal joint (MSJ) disease is a rare cause of anterior chest pain but can be a major sign of systemic arthritic involvement. In patients with ankylosing spondylitis (AS), a type of systemic arthritis, chest pain can be due to MSJ involvement and can be improved by ultrasound-guided corticosteroid injection into the joint.

Case Summary: A 64-year-old man visited our pain clinic complaining of anterior chest pain.

Unveiling the positive effect of mineral induced natural organic matter (NOM) on catalyst properties and catalytic dechlorination performance: An experiment and DFT study.

Herein, we report the significant effects of natural organic matter contained in natural zeolite (Z-NOM) on the physicochemical characteristics of a Ni/Fe@natural zeolite (NF@NZ) catalyst and its decontamination performance toward the dechlorination of trichloroethylene (TCE). Z-NOM predominantly consists of humic-like substances and has demonstrable utility in the synthesis of bimetallic catalysts. Compared to NF@NZ (devoid of Z-NOM), NF@NZ had increased dispersibility and mobility and showed significant enhancement in the catalytic dechlorination of TCE owing to the encapsulation of Ni/Fe nanoparticles by Z-NOM.

NaOH-assisted HO post-modification as a novel approach to enhance adsorption capacity of residual coffee waste biochars toward radioactive strontium: Experimental and theoretical studies.

In this study, NaOH-assisted HO post-modification was proposed as a novel strategy to enhance the adsorption of radioactive strontium (Sr) onto residual coffee waste biochars (RCWBs). To validate its viability, the adsorption capacities and mechanisms of Sr(II) using pristine (RCWB), HO post-modified (RCWB), and NaOH-assisted HO post-modified residual coffee waste biochars (RCWB) were experimentally and theoretically investigated. The highest adsorption capacity of Sr(II) for RCWB (10.

Configurational Approach to Understand Preventive Behavior Adoption among a Non-Adhering Population During the COVID-19 Pandemic.

This study examined the risk preventive responses of individuals, especially those who do not adhere to preventive measures (e.g. anti-maskers) for COVID-19, by integrating three dominant theories in risk and health communication.

Competitive adsorption of pharmaceuticals in lake water and wastewater effluent by pristine and NaOH-activated biochars from spent coffee wastes: Contribution of hydrophobic and π-π interactions.

This study investigated the competitive adsorption mechanisms of pharmaceuticals (i.e., naproxen, diclofenac, and ibuprofen) toward the pristine and NaOH-activated biochars from spent coffee wastes (SCW) in lake water and wastewater effluent.

Probing Magnetism in Artificial Metal-Organic Complexes Using Electronic Spin Relaxometry.

Single spins are considered as a versatile candidate for miniaturizing information devices down to the nanoscale. To engineer the spin's properties, metal-organic frameworks provide a promising route which in turn requires thorough understanding of the metal-molecule interaction. Here, we investigate the magnetic robustness of a single iron (Fe) atom in artificially built Fe-tetracyanoethylene (TCNE) complexes by using low-temperature scanning tunneling microscopy (STM).

Cancer Control Continuum in Korean American Community Newspapers: What Is the Association with Source Nationality-US vs. Korea?

Prior research suggests that cancer information obtained from Korean American community media, which are the primary health information sources among the population, does not connect to Korean Americans' increased cancer knowledge or cancer protective/detective behavior. We aim to identify the reason by analyzing cancer type, cancer control continuum, and cancer topic presented in Korean American community newspapers. The nationality of news source, US and Korea, and its association with the cancer coverage were examined.

Robust Powerline Equipment Inspection System Based on a Convolutional Neural Network.

Electric power line equipment such as insulators, cut-out-switches, and lightning-arresters play important roles in ensuring a safe and uninterrupted power supply. Unfortunately, their continuous exposure to rugged environmental conditions may cause physical or electrical defects in them which may lead to the failure to the electrical system. In this paper, we present an automatic real-time electrical equipment detection and defect analysis system.

Prognostic implications of and relationship between CpG island hypermethylation and repetitive DNA hypomethylation in hepatocellular carcinoma.

Purpose: This study aims to determine the relationship between CpG island DNA hypermethylation and global genomic DNA hypomethylation and their prognostic implications in hepatocellular carcinoma. The association of DNA methylation changes with clinicopathologic factors and the chronological ordering of DNA methylation changes along multistep hepatocarcinogenesis were also assessed.

Experimental Design: Hepatocellular carcinoma (n = 20) and nonneoplastic liver samples (n = 72) were analyzed for their methylation status at 41 CpG island loci and 3 repetitive DNA elements (LINE-1, ALU, and SAT2) using MethyLight or combined bisulfite restriction analysis.

Clinicopathological features of CpG island methylator phenotype-positive colorectal cancer and its adverse prognosis in relation to KRAS/BRAF mutation.

CpG island methylator phenotype (CIMP) is a recently described subset of colorectal cancers (CRC) with widespread methylation of multiple promoter CpG islands. But the prognostic implication of CIMP in CRC has not been clarified. Thus, the aim of the present study was to differentiate the unique characteristics of CIMP from those of microsatellite instability (MSI)-high CRC, especially with regard to prognosis.

Methylation profiles of multiple CpG island loci in extrahepatic cholangiocarcinoma versus those of intrahepatic cholangiocarcinomas.

Context: CpG island hypermethylation is attracting attention because of its importance as a tumor marker and its potential mechanism for the development of human cancers. Extrahepatic cholangiocarcinoma has been poorly investigated with respect to CpG island hypermethylation, and the number of genes known to be methylated in extrahepatic cholangiocarcinomas is fewer than 20.

Objective: To generate methylation profiles of 24 CpG island loci in extrahepatic cholangiocarcinomas, to correlate methylation findings with clinicopathologic findings, and to compare these findings with those of intrahepatic cholangiocarcinomas.

Methylation profiles of CpG island loci in major types of human cancers.

Several reports have described aberrant methylation in various types of human cancers. However, the interpretation of methylation frequency in various human cancers has some limitations because of the different materials and methods used for methylation analysis. To gain an insight into the role of DNA hypermethylation in human cancers and allow direct comparison of tissue specific methylation, we generated methylation profiles in 328 human cancers, including 24 breast, 48 colon, 61 stomach, 48 liver, 37 larynx, 24 lung, 40 prostate, and 46 uterine cervical cancer samples by analyzing CpG island hypermethylation of 13 genes using methylation-specific PCR.

BRAF and KRAS mutations in prostatic adenocarcinoma.

Constitutive activation of the kinase cascade involving RAS, RAF, MEK and ERK is common to human cancers, and mutations of KRAS and BRAF are mutually exclusive and serve as alternatives to activate the RAS/RAF/ERK signaling pathway. RAS mutations are known to occur in prostate adenocarcinomas, but little is known about BRAF mutations in these tumors. In the present study, BRAF and KRAS mutations were characterized in 206 prostate adenocarcinomas by enhanced PCR-RFLP and direct sequencing.
