OHCA recognized by both ML and dispatcher showed a 28 s mean difference in favour of ML (P &lt; 0.001). ML with higher FPR settings reduced recognition times.<br /><br /> ML recognized a higher proportion of OHCA within the first minute compared with dispatchers and has the potential to be a supportive tool during emergency calls. The optimal FPR settings need to be evaluated in a prospective study.<br /><br />ML recognized a higher proportion of OHCA within the first minute compared with dispatchers and has the potential to be a supportive tool during emergency calls.

Resolution of inflammation promotes the transition to tissue repair and is governed, in part, by specialized pro-resolving mediators (SPM). The complete structures of a novel series of cysteinyl-SPM (cys-SPM) were recently elucidated, and proved to stimulate tissue regeneration in planaria and resolve acute inflammation in mice. Their functions in mammalian tissue repair are of interest. Here, nine structurally distinct cys-SPM were screened and PCTR1 uniquely enhanced human keratinocyte migration with efficacy similar to epidermal growth factor. In skin wounds of mice, PCTR1 accelerated closure. Wound infection increased PCTR1 that coincided with decreased bacterial burden. Addition of PCTR1 reduced wound bacteria levels and decreased inflammatory monocytes/macrophages, which was coupled with increased expression of genes involved in host defense and tissue repair. These results suggest that PCTR1 is a novel regulator of host defense and tissue repair, which could inform new approaches for therapeutic management of delayed tissue repair and infection.3-nitropropionic acid (3-NP) is a toxin that causes neural damage in the striatum and can lead to the development of Huntington's disease manifestations in animal models. Several studies have shown genotoxicity related to the 3-NP treatment. This study investigated potential genotoxicity and mutagenicity that was induced by a low dose (6.25 mg/kg i. p.) 3-NP subacute treatment (daily, over 6 days) in a rat model. The arterial blood and the frontal cortex were analyzed by the comet assay and the bone marrow by micronucleus. Surprisingly, the 3-NP subacute treatment with the low dose did not show genotoxic or mutagenic effects.KV1.3 is a voltage-gated potassium channel that is upregulated in neuroinflammatory conditions, such as Alzheimer's disease and Parkinson's disease. HsTX1[R14A] is a potent and selective peptide blocker of KV1.3 with the potential to block microglial KV1.3, but its brain uptake is expected to be limited owing to the restrictive nature of the blood-brain barrier. To assess its peripheral and brain exposure, a LC-MS/MS assay was developed to quantify HsTX1[R14A] concentrations in mouse plasma and brain homogenate that was reliable and reproducible in the range of 6.7-66.7 nM (r2 = 0.9765) and 15-150 pmol/g (r2 = 0.9984), respectively. To assess if neuroinflammation affected HsTX1[R14A] disposition, C57BL/6 mice were administered HsTX1[R14A] subcutaneously (2 mg/kg) 24 h after an intraperitoneal dose of Escherichia coli lipopolysaccharide (LPS), which is commonly used to induce neuroinflammation; brain and plasma concentrations of HsTX1[R14A] were then quantified over 120 min. LPS treatment significantly retarded the decline in HsTX1[R14A] plasma concentrations, presumably as a result of reducing renal clearance, and led to substantial brain uptake of HsTX1[R14A], presumably through disruption of brain inter-endothelial tight junctions. This study suggests that HsTX1[R14A] may reach microglia in sufficient concentrations to block KV1.3 in neuroinflammatory conditions, and therefore has the potential to reduce neurodegenerative diseases.<br /><br /> Taiwan has launched a series of population-wide interventions to prevent hepatocellular carcinoma (HCC) related to hepatitis B and C virus infection since 1984. We took this opportunity to investigate the impact of each intervention on the incidence and case-fatality rate of HCC, and assessed their relative contributions to the overall reduction in mortality during this period.<br /><br /> Population-based registry data on HCC mortality and incidence from individuals aged 0 to 84 years between 1979 and 2016 were collected before (Period 1) and after universal hepatitis B vaccination from 1984 (Period 2), universal health care from 1995 (Period 3), and viral hepatitis therapy from 2003 (Period 4). A Bayesian Poisson regression model was used for mortality decomposition analysis to estimate the respective contributions of these interventions to the reduction in age-specific incidence and case-fatality rates.<br /><br /> Mortality declined substantially in children, young- and middle-aged groups, but only slightly decreased in thntiviral therapy were effective in reducing HCC incidence and mortality for the young and middle-aged groups, while the case-fatality rate was improved by universal health care for all age groups.<br /><br />Since 1984, a series of population-wide interventions have been launched in Taiwan to prevent viral hepatitis-related hepatocellular carcinoma, including a universal hepatitis B vaccination program (from 1984), universal health care (from 1995), and a national viral hepatitis therapy program (from 2004). Vaccination and antiviral therapy were effective in reducing HCC incidence and mortality for the young and middle-aged groups, while the case-fatality rate was improved by universal health care for all age groups.A variety of methods have been developed for quantification of infectious Ebola virus in clinical or laboratory samples, but existing methods often require extensive operator involvement, manual assay scoring, or the use of custom reagents. In this study, we utilize a recently developed Ebola-specific reporter cell line that expresses ZsGreen in response to Ebola virus infection, in conjunction with semi-automated processing and quantification techniques, to develop an unbiased, high-throughput microtitration assay for quantification of infectious Ebola virus in vitro. This assay was found to have equivalent sensitivity to a standardized plaque assay for quantifying viral titers. However, the new assay could be implemented with fewer reagents and processing steps, reduced subjectivity, and higher throughput. This assay may be useful for a variety of applications, particularly studies that require the detection or quantification of infectious Ebola virus in large numbers of samples.<br /><br /> To evaluate the effects of estetrol 15 mg/drospirenone 3 mg on ovarian function.<br /><br /> Single-center, randomized, open-label, parallel study in healthy young women with proven ovulatory cycles. Participants received either estetrol 15 mg/drospirenone 3 mg (E4/DRSP) (n=41) or ethinylestradiol 20 µg/drospirenone 3 mg (EE/DRSP) (n=41) in a 24/4-day regimen for 3 consecutive cycles. Follicular size and endometrial thickness were measured by transvaginal ultrasound every 3 days in cycles 1 and 3. Blood was sampled for hormone analysis. Ovarian function expressed as Hoogland score was based on follicular size, serum estradiol (E2) and progesterone (P) concentrations. Ovulation was defined as a ruptured follicle-like structure &gt;13 mm with serum E2 concentrations &gt;100 pmol/L and serum P concentrations &gt;5 nmol/L. We assessed return of ovulation after treatment cessation, and safety throughout the study.<br /><br /> None of the participants ovulated with E4/DRSP use, while one participant ovulated once and one participant<br /><br />Treatment with E4 15 mg/DRSP 3 mg showed complete ovulation inhibition, despite less suppression of follicle-stimulating hormone and luteinizing hormone compared to EE/DRSP. If it becomes commercially available, E4/DRSP, containing a naturally occurring estrogen, should be as effective as EE/DRSP.Sclerotinia stem rot (SSR) is a disease of soybean [Glycine max (L.) Merr] that causes severe yield losses. We studied 185 representative soybean accessions to evaluate partial SSR resistance and sequenced these by the specific-locus amplified fragment sequencing method. In total, 22,048 single-nucleotide polymorphisms (SNPs), with minor allele frequencies (MAF) ≥5% and missing data less then 3%, were developed and applied to genome-wide association study of SSR responsiveness and assess linkage disequilibrium (LD) level for candidate gene selection. We identified 18 association signals related to SSR partial resistance. Among them, six overlapped the regions of previous quantitative trait loci, and twelve were novel. We identified 243 candidate genes located in the 200 kb genomic region of these peak SNPs. Based on quantitative real-time polymerase chain reaction and haplotype analysis, Glyma.03G196000 and Glyma.20G095100, encoding pentatricopeptide repeat proteins, might be important factors in the resistance response of soybean to SSR.Bacterial dormancy plays a crucial role in maintaining the functioning and diversity of microbial communities in natural environments. However, the metabolic regulations of the dormancy of bacteria in natural habitats, especially marine habitats, have remained largely unknown. A marine bacterium, Microbulbifer aggregans CCB-MM1 exhibits rod-to-coccus cell shape change during the dormant state. Therefore, to clarify the metabolic regulation of the dormancy, differential gene expression analysis based on RNA-Seq was performed between rod- (vegetative), intermediate, and coccus-shaped cells (dormancy). The RNA-Seq data revealed that one of two distinct electron transfer chains was upregulated in the dormancy. Dissimilatory sulfite reductase and soluble hydrogenase were also highly upregulated in the dormancy. In addition, induction of the dormancy of MM1 in the absence of MgSO4 was slower than that in the presence of MgSO4. These results indicate that the sulfate-reducing pathway plays an important role in entering the dormancy of MM1.Alkaline stress is one of the abiotic stresses limiting cotton production. Though RNA-Seq analyses, have been conducted to investigate genome-wide gene expression in response to alkaline stress in plants, the response of sodium bicarbonate (NaHCO3) stress-related genes in cotton has not been reported. To explore the mechanisms of cotton response to this alkaline stress, we used next-generation sequencing (NGS) technology to study transcriptional changes of cotton under NaHCO3 alkaline stress. A total of 18,230 and 11,177 differentially expressed genes (DEGs) were identified in cotton roots and leaves, respectively. Gene ontology (GO) analysis indicated the enrichment of DEGs involved in various stimuli or stress responses. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis showed that DEGs associated with plant hormone signal transduction, amino acid biosynthesis, and biosynthesis of secondary metabolites were regulated in response to the NaHCO3 stress. [https://www.selleckchem.com/GSK-3.html GSK 3 inhibitor] We further analyzed genes enriched in secondary metabolic pathways and found that secondary metabolites were regulated to eliminate the reactive oxygen species (ROS) and improve the cotton tolerance to the NaHCO3 stress. In this study, we learned that the toxic effect of NaHCO3 was more profound than that of NaOH at the same pH. Thus, Na+, HCO3- and pH had a great impact on the growth of cotton plant. The novel biological pathways and candidate genes for the cotton tolerance to NaHCO3 stress identified from the study would be useful in the genetic improvement of the alkaline tolerance in cotton.
