Here, we are presenting a pipeline for the rapid and efficient discovery of aspartyl protease inhibitors. First, we hypothesized that hydrazine could be a multi-valent warhead to interact with the active site Asp carboxylic acids. We incorporated the hydrazine anchor in a multicomponent reaction and created a large virtual library of hydrazine derivatives synthetically accessible in one-step. Next, we performed anchor-based pharmacophore screening of the libraries and resynthesized top-ranked compounds. The inhibitory potency of the molecules was finally assessed by an enzyme activity assay and the binding mode confirmed by several soaked crystal structures supporting the validity of the hypothesis and approach. The herein reported pipeline of tools will be of general value for the rapid generation of receptor binders beyond Asp proteases. © 2020 Wiley-VCH Verlag GmbH & Co.

For the first time, deferasirox and some of its derivatives were evaluated for their in vitro inhibitory activity against Jack bean urease. The potencies of the members of this class of compounds are greater than that of acetohydroxamic acid. Selleckchem BIX 01294 Compounds 7d and 7e, analogs bearing tetrazole and hydrazine derivatives (bioisoester of carboxylate group), represented the most potent urease inhibitory activity with IC 50 values of 1.268 and 3.254 µM, respectively. In silico docking studies were performed to delineate possible binding modes of the compounds with the enzyme, urease. Docking analysis suggests that the synthesized compounds were anchored well in the catalytic site and extending to the entrance of binding pocket and thus restrict the mobility of the flap by interacting with its key amino acid residues, CME592 and His593. The overall results of urease inhibition have shown that these target compounds can be further optimized and developed as a lead skeleton for discovery of novel urease inhibitors. © 2020 WILEY-VCH Verlag GmbH & Co.

This study aims to describe the epidemiology of and the risk factors for mortality in these patients. STUDY DESIGN This is a retrospective cohort study including all consecutive PICU oncology admissions from 2011 to 2017. Demographic and clinical risk factors between survivors and nonsurvivors were compared. Both univariate and multivariate Cox proportional hazard regression models were used to quantify the association between 60-day mortality and admission categories, accounting for other covariates (Pediatric Risk Of Mortality [PRISM] III score and previous bacteremia). MAIN OUTCOME MEASURES The primary outcome was 60-day mortality. RESULTS The median (interquartile range) age and PRISM III scores of pediatric oncology patients admitted to the PICU were 7 (3, 12) years and 3 (0, 5), respectively. The most common underlying oncological diagnoses were brain tumors (73/200 [36.5%]) and acute lymphoblastic leukemia (36/200 [18.0%]). Emergency admissions accounted for approximately half of all admissions (108/200 [54.0%]), including cardiovascular (24/108 [22.2%]), neurology (24/108 [22.2%]), respiratory (22/108 [20.4%]), and "other" indications (38/108 [35.2%]). The overall 60-day mortality was 35 of 200 (17.5%). Independent risk factors for mortality were emergency respiratory and neurology categories of admission (adjusted hazard ratio[aHR] 5.62, 95% confidence interval [95% CI] 1.57, 20.19; P = .008 and aHR 6.96, 95% CI 2.04, 23.75; P = .002, respectively) and previous bacteremia (aHR 3.37, 95% CI 1.57, 7.20; P = .002). CONCLUSION Emergency respiratory and neurology admissions and previous bacteremia were independent risk factors for 60-day mortality for pediatric oncological patients admitted to the PICU. © 2020 Wiley Periodicals, Inc.INTRODUCTION Many medical professionals unofficially use quick methods for saving time. However, the evidence of such assessments is limited. The main aim of this article is verifying the agreement of these methods. OBJECTIVES Overall, 106 out-patients were simultaneously evaluated with respect to the respiratory time measurement (RTM; 60 divided by the single respiratory time), 15 seconds period quadruple respiratory rate (15secRR; 15 seconds respiratory rate multiplied by 4), and 1-min respiratory rate (1minRR; gold standard respiratory rate). METHOD We assessed the correlation, Bland-Altman plot, kappa value, and normalized root mean square error of the quick methods for the respiratory rate, with 1minRR as the gold standard. RESULTS The mean±standard deviation of 1minRR, RTM, and 15secRR are 20.4±5.6,19.1±5.7, and 21.4±6.5 breathes per minute, respectively. The correlation between RTM and 1minRR was 0.85 (95% confidence interval [95% CI] 0.79-0.90), while that between 15secRR and 1minRR was 0.81 (95% CI 0.74-0.87). The kappa coefficients between RTM and 1minRR, between 15secRR and 1minRR, and between RTM and 15secRR were 0.57 (95% CI 0.41-0.72), 0.59 (95% CI 0.43-0.74), and 0.37 (95% CI 0.20-0.53), respectively. The normalized root mean square error between RTM and 1minRR was 16.9% and that between 15secRR and 1minRR was 15.0%. The Bland Altman plot demonstrated that RTM and 15secRR showed contrasting characteristics. CONCLUSION Compared to the gold standard, RTM tends to underestimate, while 15secRR tends to overestimate the respiratory rate. Therefore, health care professionals should be aware of this methodological tendency to assess vital signs properly. This article is protected by copyright.

Inspired by this opinion, numerous apoptosis inducers have been developed to treat animal diseases, especially in anticancer field. However, few studies reported to develop that kind of inductive agents for attacking plant pathogens by activation of apoptosis. With the aim of exploring and discovering abovementioned apoptosis inducers targeting phytopathogens, herein, a cluster of piperazine-tailored ursolic acid (UA) hybrids was systematically fabricated. RESULTS In vitro testing announced that title molecules could inhibit the growth of two intractable bacterial strains, defined as Xanthomonas oryzae pv. oryzae and X. axonopodis pv. citri. The corresponding lowest EC50 values were 0.37 and 1.08 μg/mL, which exceeded those of UA (> 400 μg/mL) and positive controls. Moreover, compounds 5u and 5v could manage bacterial blight in vivo using pot experiments. Flow cytometer analysis indicted that title compounds could induce distinct apoptotic behaviors on tested bacteria. In-depth study revealed that the introduction of designed compounds could reduce the enzyme activities of catalase and superoxide dismutase, and subsequently leading to the accumulation of reactive oxygen species. CONCLUSION This study can promote the development of apoptosis initiators for managing bacterial infections in agriculture by an innovative mode of action. This article is protected by copyright.

METHODS We conducted a Delphi study to develop a consensus on the necessary and desirable psychological intervention strategies for chronic pain management. First, we identified 49 components of treatments that had been used in a treatment evaluated in a randomized controlled trial (RCT) through a systematic review. In the first round of the Delphi process, 23 (32% of 72) authors who had completed RCTs in chronic pain took part. In round 2, these experts plus clinicians working at pain management programs around Australia were invited to take part, and 44 experts completed the study. RESULTS The panel agreed that it was necessary to include psycho-education, particularly about pain mechanisms and the role of thoughts in maintaining pain. Cognitive approaches were deemed necessary, although the panel did not specify one particular strategy. Finally, approaches to increase activity were deemed necessary, including the strategies of pacing, goal setting, graded exposure. Relaxation training and relapse prevention were also deemed necessary. CONCLUSIONS There was a consensus that there were many desirable strategies to include in psychological chronic pain management approaches, but that treatments should include psychoeducation, approaches to increase activity and cognitive approaches as a first line of intervention. Where patients fail to benefit from these approaches, experts identified other desirable strategies that could be utilized. This article is protected by copyright.

We investigated its role in the pine wood nematode (PWN), Bursaphelenchus xylophilus, the causative agent of pine wilt disease (PWD), to find promising control strategies against PWD. RESULTS We analysed the expression levels of PtRBOH1 and PtRBOH2, which regulate reactive oxygen species (ROS) metabolism, in Pinus thunbergii and the expression of three autophagy genes, BxATG5, BxATG9 and BxATG16, in PWN by quantitative reverse transcription-polymerase chain reaction (qRT-PCR), and measured the content of H2 O2 , the main product of ROS metabolism, in pine stem. There was a correlation between the expression of autophagy genes in PWN and pine ROS metabolism during early infection. We also found that oxidative stress induces autophagy in PWN according to qRT-PCR, transmission electron microscopy and Western blot analyses. Inhibition of autophagy by 3-methyladenine or silencing of the autophagy genes BxATG9 and BxATG16 in PWN showed that autophagy is essential for feeding, fecundity, egg hatching and survival of PWN under oxidative stress, confirming the importance of autophagy in the antioxidant defences of PWN. Similarly, we demonstrated that autophagy contributes to the virulence of PWN. Moreover, PWN likely ameliorates oxidative damage by enhancing the activities of the peroxidase and catalase antioxidant pathways when autophagy is inhibited. CONCLUSION Autophagy contributes to resistance to the oxidative stress induced by pine ROS metabolism, thus promoting infection by PWN. Our findings clarify the defence mechanisms of PWN and the pathogenesis of PWD, and provide promising hints for control of PWD by blocking autophagy. © 2020 Society of Chemical Industry.
