In the mantle and gills, the expression of P-glycoprotein (P-gp) was significantly induced at the end of the accumulation phase and significantly inhibited at the end of the depuration phase. In the digestive gland, the expression of P-gp was induced at the end of both the accumulation and depuration phases. Heat shock protein (hsp70) expression exhibited an overall increasing trend throughout the experiment.

The efficacy of catheter ablation from the noncoronary aortic cusp (NCC) of verapamil-sensitive atrial tachycardia arising near the atrioventricular node (AVN-AT) has yet to be fully clarified.

We elucidated the determinant of an effective AVN-AT ablation from the NCC.

After identifying the earliest atrial activation site (EAAS) during tachycardia, the direction of the slow conduction zone (SCZ) of the reentry circuit was identified by demonstrating manifest entrainment in 26 patients with AVN-AT. Catheter ablation was initially performed from the NCC irrespective of the local activation time. If NCC ablation was ineffective, catheter ablation was performed targeting the SCZ entrance. Then the anatomical relationship between the SCZ and the successful ablation site was elucidated.

NCC catheter ablation terminated AVN-AT in 14 patients (NCC group) but not in 12 (non-NCC group). Catheter ablation targeting the SCZ entrance terminated all non-NCC group ATs. The local activation time at the NCC relative to the EAAS did not differ between the NCC and non-NCC groups (10.1 ± 6.5 ms vs 11.2 ± 4.8 ms; P = .6333). The direction of the SCZ was posterior to the EAAS in all NCC group patients; however, it was posterolateral (n = 5) and lateral (n = 7) to the EAAS in the non-NCC group, suggesting that the SCZ existed in the direction of the NCC in the NCC group but was away from the NCC in the non-NCC group.

A close proximity between the NCC and the SCZ of the reentry circuit, but not the local activation time at the NCC, determined the efficacy of NCC catheter ablation in AVN-ATs.

Cardiovascular implantable electronic device (CIED) infections are associated with increased mortality and morbidity.

This study sought to evaluate the impact of early vs delayed transvenous lead removal (TLR) on in-hospital mortality and outcomes in patients with CIED infection.

Using the nationally representative, all payer, Nationwide Readmissions Database, we evaluated patients undergoing TLR for CIED infection between January 1, 2016, and December 31, 2018. The timing of TLR was determined on the basis of hospitalization days after the initial admission for CIED infection. The impact of early (≤7 days) vs delayed (>7 days) TLR on mortality and major adverse events was studied.

Of the 12,999 patients who underwent TLR for CIED infection, 8834 (68%) underwent early TLR and 4165 (32%) underwent delayed TLR. Delayed TLR was associated with a significant increase in in-hospital mortality (8.3% vs 3.5%; adjusted odds ratio 1.70; 95% confidence interval 1.43-2.03; P < .001). Subgroup analysis of patients with CIED infection and systemic infection showed that delayed TLR in patients with systemic infection was associated with a higher rate of in-hospital mortality compared with early TLR (10.4% vs 7.5%; adjusted odds ratio 1.24; 95% confidence interval 1.04-1.49; P < .019). Delayed TLR was also associated with significantly higher adjusted odds of major adverse events and postprocedural length of stay.

These data suggest that delayed TLR in patients with CIED infection is associated with increased in-hospital mortality and major adverse events, especially in patients with systemic infection.

State-of-the-art process trace classification resorts to deep learning, a very powerful technique which however suffers from the lack of explainability. In this paper we aim at addressing this issue, motivated by a relevant application, i.e., the classification of process traces for quality assessment in stroke management. To this end we introduce the novel concept of trace saliency maps, an instrument able to highlight what trace activities are particularly significant for the classification task. Through trace saliency maps we justify the output of the deep learning architecture, and make it more easily interpretable to medical users. The good results in our use case have shown the feasibility of the approach, and let us make the hypothesis that it might be translated to other application settings and to other black box learners as well.Oxidative post-translational modifications of specific chloroplast proteins contribute to the initiation of retrograde signaling. The Arabidopsis thaliana EXECUTER1 (EX1) protein, a chloroplast-localized singlet oxygen (1O2) sensor, undergoes tryptophan (Trp) 643 oxidation by 1O2, a chloroplast-derived and light-dependent reactive oxygen species. The indole side chain of Trp is vulnerable to 1O2, leading to the generation of oxidized Trp variants and priming EX1 for degradation by a membrane-bound FtsH protease. The perception of 1O2 via Trp643 oxidation and subsequent EX1 proteolysis facilitate chloroplast-to-nucleus retrograde signaling. In this study, we discovered that the EX1-like protein EX2 also undergoes 1O2-dependent Trp530 oxidation and FtsH-dependent turnover, which attenuates 1O2 signaling by decelerating EX1-Trp643 oxidation and subsequent EX1 degradation. Consistent with this finding, the loss of EX2 function reinforces EX1-dependent retrograde signaling by accelerating EX1-Trp643 oxidation and subsequent EX1 proteolysis, whereas overexpression of EX2 produces molecular phenotypes opposite to those observed in the loss-of- function mutants of EX2. click here Intriguingly, phylogenetic analysis suggests that EX2 may have emerged evolutionarily to attenuate the sensitivity of EX1 toward 1O2. Collectively, these results suggest that EX2 functions as a negative regulator of the EX1 signalosome through its own 1O2-dependent oxidation, providing a new mechanistic insight into the regulation of EX1-mediated 1O2 signaling.MicroRNAs (miRNAs) play important roles in plant physiological activities. However, their roles and molecular mechanisms in boosting plant immunity, especially through the modulation of macronutrient metabolism in response to pathogens, are largely unknown. Here, we report that an evolutionarily conserved miRNA, miR395, promotes resistance to Xanthomonas oryzae pv. oryzae (Xoo) and X. oryzae pv. oryzicola (Xoc), two destructive bacterial pathogens, by regulating sulfate accumulation and distribution in rice. Specifically, miR395 targets and suppresses the expression of the ATP sulfurylase gene OsAPS1, which functions in sulfate assimilation, and two sulfate transporter genes, OsSULTR2;1 and OsSULTR2;2, which function in sulfate translocation, to promote sulfate accumulation, resulting in broad-spectrum resistance to bacterial pathogens in miR395-overexpressing plants. Genetic analysis revealed that miR395-triggered resistance is involved in both pathogen-associated molecular pattern-triggered immunity and R gene-mediated resistance. Moreover, we found that accumulated sulfate but not S-metabolites inhibits proliferation of pathogenic bacteria, revealing a sulfate-mediated antibacterial defense mechanism that differs from sulfur-induced resistance. Furthermore, compared with other bacteria, Xoo and Xoc, which lack the sulfate transporter CysZ, are sensitive to high levels of extracellular sulfate. Accordingly, miR395-regulated sulfate accumulation impaired the virulence of Xoo and Xoc by decreasing extracellular polysaccharide production and biofilm formation. Taken together, these results suggest that rice miR395 modulates sulfate metabolism to exploit pathogen sensitivity to sulfate and thereby promotes broad-spectrum resistance.Despite continuous improvements, it is difficult to efficiently amplify large sequences from complex templates using current PCR methods. Here, we developed a suppression thermo-interlaced (STI) PCR method for the efficient and specific amplification of long DNA sequences from genomes and synthetic DNA pools. This method uses site-specific primers containing a common 5' tag to generate a stem-loop structure, thereby repressing the amplification of smaller non-specific products through PCR suppression (PS). However, large target products are less affected by PS and show enhanced amplification when the competitive amplification of non-specific products is suppressed. Furthermore, this method uses nested thermo-interlaced cycling with varied temperatures to optimize strand extension of long sequences with an uneven GC distribution. The combination of these two factors in STI PCR produces a multiplier effect, markedly increasing specificity and amplification capacity. We also developed a webtool, calGC, for analyzing the GC distribution of target DNA sequences and selecting suitable thermo-cycling programs for STI PCR. Using this method, we stably amplified very long genomic fragments (up to 38 kb) from plants and human and greatly increased the length of de novo DNA synthesis, which has many applications such as cloning, expression, and targeted genomic sequencing. Our method greatly extends PCR capacity and has great potential for use in biological fields.

The long-term efficacy and safety of upadacitinib was evaluated in an open-label extension (OLE) of a phase II, double-blind, randomized trial of patients with Crohn's disease.

Patients who completed the 52-week study (CELEST) received upadacitinib in the CELEST OLE as follows those who had received immediate-release upadacitinib 3, 6, or 12 mg twice daily or 24 mg once daily (QD) received extended-release upadacitinib 15 mg QD and those who had received immediate-release upadacitinib 12 or 24 mg twice daily as rescue therapy received extended-release upadacitinib 30 mg QD. If any patient initiating upadacitinib 15 mg QD in CELEST OLE lost response at or after week 4, the dose was escalated to upadacitinib 30 mg QD (dose-escalated group). Clinical, endoscopic, inflammatory and quality-of-life measures were assessed.

A total of 107 CELEST study completers entered CELEST OLE. The proportion of patients with clinical remission 2.8/1.0 was maintained between week 0 and month 30 in all groups (month 30 15 mg, 61%; 30 mg, 54%; dose-escalation, 55%). Endoscopic response was maintained in all groups (month 24 68%, 67%, and 40%, respectively). The rates of adverse events (AEs), serious AEs, AEs leading to discontinuation, infections, serious infections, herpes zoster, and creatine phosphokinase elevation were higher with upadacitinib 30 mg vs 15 mg.

Sustained long-term benefit at 30 months and further endoscopic improvements to month 24 were observed in patients with Crohn's disease receiving upadacitinib. Safety over 30 months was consistent with the known safety profile of upadacitinib. Clinicaltrials.gov ID no NCT02782663.
