Enhanced oxidation of parabens in an aqueous solution by air-assisted cold plasma.

Various contaminants of emerging concern (CECs) including pharmaceuticals and personal care products (PPCPs) have been known to threaten the aquatic ecosystem and human health even at low levels in surface water. Among them, the wide variety use of parabens as preservatives may pose potential threat to human because parabens may present estrogenic activity. Various advanced oxidation processes have been attempted to reduce parabens, but challenges using cold plasma (CP) are very rare.

Effectiveness of a dispatcher-assisted CPR using an animated image: Simulation study.

Introduction: Considering the few studies evaluating bystander cardiopulmonary resuscitation (CPR) performance, we sought to analyze differences in bystander CPR performance with and without the use of our self-developed animated GIFs based on dispatcher-assisted CPR simulation.

Methods: A total of 80 adults who had not received CPR training over the past two years participated in the study. Among them, 40 people were classified into the auditory group (receiving CPR instructions only over the phone), and the other 40 people were classified into the audiovisual group (receiving CPR instructions over the phone after receiving images on a smartphone).

Two cases of extraluminal migration of fishbones into the thyroid gland and submandibular gland.

Laryngopharyngeal or cervical pain following ingestion of foreign bodies is one of the most frequently encountered emergencies in otolaryngologic practice. Although most of these foreign bodies can be easily removed under laryngoscopic examination without any complications, surgical removal may be required when foreign bodies migrate extraluminally. This report describes two rare cases of ingested fishbones that had migrated, one each to the thyroid gland and submandibular gland.

A Sustainable Ambulance Operation Model in a Low-Resource Country (the Democratic Republic of Congo).

Due to an increase in traffic collisions, the demand for prehospital medical services is on the rise, even in low-resource countries where emergency ambulance services have not been previously provided. To build a sustainable and continuous prehospital ambulance operation model, it is necessary to consider the medical system and economic conditions of the corresponding country. In an attempt to construct a prehospital ambulance operation model that ensures continuous operation, a pilot "emergency patient transporting service from field to hospital" operation was established for approximately three months in Kinshasa, the capital of the DR Congo.

Dominant high expression of wild-type HSP110 defines a poor prognostic subgroup of colorectal carcinomas with microsatellite instability: a whole-section immunohistochemical analysis.

The aim of this study is to establish heat shock protein 110 (HSP110) as a prognostic biomarker of colorectal carcinomas (CRCs) with microsatellite instability-high (MSI-H) by considering the intratumoral heterogeneity of HSP110 expression. We performed whole-section immunohistochemistry (IHC) for wild-type HSP110 (HSP110wt) in 164 MSI-H CRCs. The intensity of the HSP110wt expression in tumor cells was semiquantitatively scored (0/1/2/3), and the HSP110wt expression status of each tumor was classified as low or high using the following four scoring criteria: H-score, dominant intensity score, lowest intensity score, and highest intensity score.

Inhibitory effect of obovatol from Magnolia obovata on the Salmonella type III secretion system.

In many pathogenic Gram-negative bacteria, such as Salmonella, Escherichia coli, Yersinia and Chlamydia spp., which cause diseases in humans, the type III secretion system (TTSS) is an important virulence factor that translocates effector proteins into the cytosol of host cells. Thus, the TTSS is a good target for antibacterial agents.

There remains a need for a control strategy to enrich them in a photobioreactor. This study performed a series of batch experiments using a mixotroph, , to characterize optimal guidelines of mixotrophic growth based on a statistical design of the experiment.

Deletion in HSP110 T: correlation with wild-type HSP110 expression and prognostic significance in microsatellite-unstable advanced gastric cancers.

Deletion of the HSP110 T mononucleotide repeat has recently been identified as a prognostic marker that is correlated with wild-type HSP110 (HSP110wt) expression in microsatellite instability-high (MSI-H) colorectal cancers. The aim of this study was to assess the correlation between deletion of the HSP110 T repeat and expression of HSP110wt using DNA testing and immunohistochemistry and to determine the prognostic implications of HSP110 T deletion in MSI-H advanced gastric cancers (GCs). The status of HSP110wt expression was evaluated by immunohistochemistry using an HSP110wt-specific antibody in 142 MSI-H advanced GCs.

Distinct clinical outcomes of two CIMP-positive colorectal cancer subtypes based on a revised CIMP classification system.

Background: Colorectal cancer (CRC) is a heterogeneous disease in terms of molecular carcinogenic pathways. Based on recent findings regarding the multiple serrated neoplasia pathway, we revised an eight-marker panel for a new CIMP classification system.

Methods: 1370 patients who received surgical resection for CRCs were classified into three CIMP subtypes (CIMP-N: 0-4 methylated markers, CIMP-P1: 5-6 methylated markers and CIMP-P2: 7-8 methylated markers).

Downregulation of acetyl-CoA synthetase 2 is a metabolic hallmark of tumor progression and aggressiveness in colorectal carcinoma.

Acetyl-CoA synthetase-2 is an emerging key enzyme for cancer metabolism, which supplies acetyl-CoA for tumor cells by capturing acetate as a carbon source under stressed conditions. However, implications of acetyl-CoA synthetase-2 in colorectal carcinoma may differ from other malignancies, because normal colonocytes use short-chain fatty acids as an energy source, which are supplied by fermentation of the intestinal flora. Here we analyzed acetyl-CoA synthetase-2 mRNA expression by reverse-transcription quantitative PCR in paired normal mucosa and tumor tissues of 12 colorectal carcinomas, and subsequently evaluated acetyl-CoA synthetase-2 protein expression by immunohistochemistry in 157 premalignant colorectal lesions, including 60 conventional adenomas and 97 serrated polyps, 1,106 surgically resected primary colorectal carcinomas, and 23 metastatic colorectal carcinomas in the liver.

Out-of-hospital cardiac arrest patients treated with cardiopulmonary resuscitation using extracorporeal membrane oxygenation: focus on survival rate and neurologic outcome.

Background: Extracorporeal membrane oxygenation (ECMO) is a useful treatment for refractory out-of-hospital cardiac arrest (OHCA). However, little is known about the predictors of survival and neurologic outcome after ECMO. We analyzed our institution's experience with ECMO for refractory OHCA and evaluated the predictors of survival and neurologic outcome after ECMO.

Associations and prognostic implications of Eastern Cooperative Oncology Group performance status and tumoral LINE-1 methylation status in stage III colon cancer patients.

Background: Low methylation status of LINE-1 in tumors is associated with poor survival in patients with colon cancer. Eastern Cooperative Oncology Group performance status (ECOG-PS) is a method to assess the functional status of a patient. We retrospectively evaluated the relationship between ECOG-PS and LINE-1 methylation in colorectal cancers (CRCs) and their prognostic impact in CRC or colon cancer patients receiving adjuvant 5-fluorouracil/leucovorin/oxaliplatin (FOLFOX).

The prognostic value of the grey-to-white matter ratio in cardiac arrest patients treated with extracorporeal membrane oxygenation.

Aim: The grey-to-white matter ratio (GWR) is a reliable predictor of the neurological outcome of out-of-hospital cardiac arrest (OHCA). However, the reliability in patients receiving extracorporeal membrane oxygenation-assisted cardiopulmonary resuscitation (ECPR) remains unknown. We evaluated the utility of the GWR in predicting neurological outcomes in ECPR-treated patients.

The pre-ECMO simplified acute physiology score II as a predictor for mortality in patients with initiation ECMO support at the emergency department for acute circulatory and/or respiratory failure: a retrospective study.

Background: In the emergency department (ED), extracorporeal membrane oxygenation (ECMO) can be used as a rescue treatment modality for patients with refractory circulatory and/or respiratory failure. Serious consideration must be given to the indication, and the PRESERVE and RESP scores for mortality have been investigated. However these scores were validated to predict survival in patients who received mainly veno-venous (VV) ECMO in the intensive care unit.

Prognostic significance of promoter CpG island hypermethylation and repetitive DNA hypomethylation in stage I lung adenocarcinoma.

In carcinogenesis of peripheral pulmonary carcinomas, multiple genetic and epigenetic alterations are involved. In this study, we quantified methylation levels of repetitive DNA elements (L1 and Alu) and six CpG island methylator phenotype (CIMP)-panel markers in various lesions representing steps in the development of lung adenocarcinoma (ADC), including atypical adenomatous hyperplasia, adenocarcinoma in situ, and invasive ADC. We then assessed methylation levels in an independent set of stage I ADCs (n = 100) and correlated methylation status with clinicopathological findings and clinical outcome.
