We hypothesized that nationwide social distancing and other preventive measures for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were associated with reduced detection of other respiratory viruses in South Korea.

We analyzed national surveillance data to compare incidence of respiratory viruses during 2016-2019 vs. 2020. Results of multiplex reverse transcriptase-polymerase chain reaction assays for eight respiratory viruses were included adenovirus (ADV), parainfluenza virus (PIV), respiratory syncytial virus (RSV), influenza virus (IFV), human coronavirus (HCoV; non-SARS-CoV-2), human rhinovirus (HRV), human bocavirus (HBoV), and human metapneumovirus (HMPV).

During 2016-2019, rates of detection of respiratory viruses were relatively stable ADV, 3.7%-9.2%; PIV, 1.4%-17.0%; RSV, 0.3%-15.3%; IFV, 0.4%-35.6%; HCoV, 1.5%-8.4%; HRV, 7.0%-25.1%; HBoV, 0.6%-6.3%; and HMPV, 0.7%-14.5%. Following implementation of social distancing in February 2020, rates of detection of enveloped viruses (HCoV, HMPV, IFV, PIV and RSV) were significantly reduced by up to 100%. However, non-enveloped viruses (ADV, HRV and HBoV) persisted throughout 2020, and HRV rates in hospitalized patients significantly increased.

After implementation of social distancing for SARS-CoV-2 in South Korea, rates of detection of enveloped respiratory viruses decreased significantly, whereas non-enveloped viruses persisted, suggesting that enhanced infection prevention strategies are required to mitigate spread of these viruses.

Which miRNAs regulate a particular target gene or target pathway in a certain physiological context? Answering such common research questions can be time consuming and labor intensive. Especially for researchers without computational experience, the integration of different data sources, selection of the right parameters and concise visualization can be demanding. A comprehensive analysis should be central to present adequate answers to complex biological questions. With miRTargetLink 2.0, we develop an all-in-one solution for human, mouse and rat miRNA networks. MEK inhibitor clinical trial Users input in the unidirectional search mode either a single gene, gene set or gene pathway, alternatively a single miRNA, a set of miRNAs or an miRNA pathway. Moreover, genes and miRNAs can jointly be provided to the tool in the bidirectional search mode. For the selected entities, interaction graphs are generated from different data sources and dynamically presented. Connected application programming interfaces (APIs) to the tailored enrichment tools miEAA and GeneTrail facilitate downstream analysis of pathways and context-annotated categories of network nodes.

The relationship between guideline adherence for radical cystectomy of non-muscle-invasive bladder cancer and patient prognoses currently remains unclear. We investigated whether guideline adherence at the time of non-muscle-invasive bladder cancer affects the oncological outcomes of bladder cancer patients who underwent radical cystectomy.

Among 267 cTa-4N0-2M0 bladder cancer patients, 70 who underwent radical cystectomy under the non-muscle-invasive bladder cancer or muscle-invasive bladder cancer status that progressed from non-muscle-invasive bladder cancer were identified. Patients who followed the guidelines from initial transurethral resection of bladder tumors to radical cystectomy were defined as the guideline adherent group (n=52), while those who did not were the guideline non-adherent group (n=18).

In the guideline non-adherent group, 8 (44.4%) out of 18 were diagnosed with highest risk non-muscle-invasive bladder cancer for Bacillus Calmette Guérin-naïve patients and 7 (38.9%) had a Bacillu.

Guideline adherence during the time course of the non-muscle-invasive bladder cancer stage may result in a favorable prognosis of patients who receive radical cystectomy. Even under non-muscle-invasive bladder cancer status, radical cystectomy needs to be performed with adequate timing under guideline recommendations.Electronic nicotine delivery system (ENDS) use has become a popular, generally regarded as safe, alternative to tobacco use. The e-liquids used for ENDS vapor generation commonly contain flavoring agents, such as maltol, which have been subjected to little investigation of their effects on lung health from ENDS usage. In the present study, we examined the impacts of firsthand (3.9 mM) and secondhand (3.9 µM) exposure levels to maltol-flavored ENDS vapors on lung metabolism. Human lung bronchial epithelial cells were exposed to ENDS vapors using a robotic system for controlled generation and delivery of exposures, and the effects on metabolism were evaluated using high-resolution metabolomics. The results show that maltol in e-liquids impacts lung airway epithelial cell metabolism at both firsthand and secondhand exposure levels. The effects of maltol were most notably seen in amino acid metabolism while oxidative stress was observed with exposure to all ENDS vapors including e-liquids alone and maltol-contained e-liquids. Many effects of firsthand exposure were also observed with secondhand exposure, suggesting need for systematic investigation of both firsthand and secondhand effects of flavored ENDS vapors on lung metabolism and risk of lung disease.The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor well-known for its adaptive role as a sensor of environmental toxicants and mediator of the metabolic detoxification of xenobiotic ligands. In addition, a growing body of experimental data has provided indisputable evidence that the AHR regulates critical functions of cell physiology and embryonic development. Recent studies have shown that the naïve AHR-that is, unliganded to xenobiotics but activated endogenously-has a crucial role in maintenance of embryonic stem cell pluripotency, tissue repair, and regulation of cancer stem cell stemness. Depending on the cellular context, AHR silences the expression of pluripotency genes Oct4 and Nanog and potentiates differentiation, whereas curtailing cellular plasticity and stemness. In these processes, AHR-mediated contextual responses and outcomes are dictated by changes of interacting partners in signaling pathways, gene networks, and cell-type-specific genomic structures. In this review, we focus on AHR-mediated changes of genomic architecture as an emerging mechanism for the AHR to regulate gene expression at the transcriptional level.
