KGaA, Weinheim.Here we present an"immortal" N -(diphenylphosphanyl)-1,3-diisopropyl-4,5-dimethyl-1,3-dihydro-2H -imidazol-2-imine/diisobutyl (2,6-di-tert-butyl-4-methylphenoxy) aluminum (P(NIiPr)Ph2/(BHT)AliBu2)-based frustrated Lewis pair (FLP) polymerization strategy for rapid and scalable synthesis of the sequence-controlled multiblock copolymers at room temperature. Without addition of extra initiator or catalyst and complex synthetic procedure, this method enabled us to achieve a tripentacontablock copolymer (n = 53, k = 4, dp n = 50) with the world's highest block number (n = 53) and molecular weight (M n = 310 kg/mol) within 30 min. More importantly, this FLP polymerization strategy provided access to the multiblock copolymers with tailored properties by precisely adjusting the monomer sequence and block numbers. © 2020 WILEY-VCH Verlag GmbH & Co.

A deep understanding of traditional ceramics is an essential key to designing new ceramic materials. The demanding synthesis of ceramics with fine-tuned properties, such as enhanced mechanical, electrical, optical or magnetic characteristics, must be associated with cutting-edge analysis procedures in order to improve the engineering process. In this context, we describe a neutron-based non-destructive approach to investigating the nanoporosity of an historical pottery matrix as an effective investigation technique for exploring both traditional and advanced ceramic materials. © 2020 Wiley-VCH Verlag GmbH & Co.

Dolastatin 15 is a microtubule destabilizing agent with analogues undergoing clinical evaluation. Profiling against a panel of isogenic HCT116 colorectal cancer cells showed remarkable differential cytotoxicity against the parental cells over isogenic cells lacking HIF or other key players in the pathway, including oncogenic KRAS and VEGF. Dolastatin 15 displayed anti-vascularization effect in human endothelial cells and in zebrafish vhl mutants with activated Hif, signifying its clinical potential as a treatment for solid tumors with an angiogenic component. Global transcriptome analysis using RNA-sequencing suggested that dolastatin 15 could affect other major cancer pathways that may not directly involve tubulin or HIF. The identification of the true producer of a clinically relevant agent is important for sustainable supply, understanding the biosynthesis and future genetic manipulation of the biosynthetic gene cluster for analogue production. © 2020 WILEY-VCH Verlag GmbH & Co.

Herein, we designed FeOOH@ZIF-8 composites with enhanced ionization efficiency and size-exclusion effect for laser desorption/ionization mass spectrometry (LDI MS) based metabolic diagnosis of gynecological cancers. The FeOOH@ZIF-8 assisted LDI MS achieved rapid, sensitive, and selective metabolic fingerprints of the native serum without any enrichment or purification. Further analysis of extracted serum metabolic fingerprints successfully discriminated patients with gynecological cancers (GCs) from healthy controls and also differentiated three major subtypes of GCs. Given the low cost, high-throughput, and easy operation, our approach brings a new dimension to disease analysis and classification. © 2020 WILEY-VCH Verlag GmbH & Co.

Research aiming at developing effective therapies for controlling nerve agent-induced SE is commonly performed in adult rats. The characteristics of nerve agent-induced SE in young rats are less clear; relevant knowledge is necessary for developing effective pediatric therapies. Here, we have used electroencephalographic (EEG) recordings and analysis to study seizures in postnatal day 21 rats exposed to 1.2 × LD50 of soman, and compared the antiseizure efficacy of midazolam (MDZ)-currently considered by the Food and Drug Administration to replace diazepam for treating SE in victims of nerve agent exposure-with that of LY293558, an AMPA/GluK1 receptor antagonist, administered in combination with caramiphen, an antimuscarinic with N-methyl-d-aspartate receptor antagonistic properties. Prolonged SE developed in 80% of the rats and was reflected in behavioral seizures/convulsions. Both MDZ and LY293558 + caramiphen stopped the SE induced by soman, but there was a significant recurrence of seizures within 24 h postexposure only in the MDZ-treated group, as revealed in the raw EEG data and their representation in the frequency domain using a fast Fourier transform and in spectral analysis over 24 hours. In contrast to the high efficacy of LY293558 + caramiphen, MDZ is not an effective treatment for SE induced by soman in young animals. © Published 2020.

METHODS Gadolinium-enhanced tumors of 258 primary and single IHPCs were segmented semi-automatically, followed by manual checking and editing of boundaries. The lesions were registered to Montreal Neurological Institute standard anatomical space, and heat-map and 3-dimensional rendered frequency images were generated. All tumors were then superimposed on the Anatomical Automatic Labeling (AAL) template to further investigate the difference in the tumor location based on the voxel-wise frequency of occurrence with respect to laterality, sex, age, and pathologic grade. RESULTS The 3-dimensional rendered images show that the tumors commonly located in the posterior cranial cavity, surrounding the tentorium. The posterior third of the superior sagittal sinus and the confluence of sinuses were commonly affected. According to the analysis of tumor occurrence frequency in the AAL template, IHPCs were mainly observed in the limbic lobe, occipital lobe, and cerebellum. Tumors in younger patients preferentially located in the right occipital region (P = .027), whereas those with higher pathological grade more often located in the left parietal lobe (P = .034). CONCLUSIONS This is the first voxel-based study to explore the predilection site of IHPCs. Our study suggests that these tumors commonly affect the posterior cranial cavity, adjoining the tentorium and venous sinus. Further research is needed to investigate the possible factors underlying these topographic preferences. © 2020 by the American Society of Neuroimaging.1,25-dihydroxyvitamin D3 (1,25(OH)2 D3, VitD3) is the major active ingredient of vitamin D and has anti-inflammatory activity; however, the mechanism for this remains poorly understood. In this study, we found that VitD3 was able to abolish NOD-like receptor protein 3 (NLRP3) inflammasome activation and subsequently inhibit caspase-1 activation and IL-1β secretion via the vitamin D receptor (VDR). Angiotensin Receptor antagonist Furthermore, VitD3 specifically prevented NLRP3-mediated apoptosis-associated speck-like protein with a caspase-recruitment domain (ASC) oligomerization. In additional to this, NLRP3 binding to NIMA-related kinase 7 (NEK7) was also inhibited. Notably, VitD3 inhibited autophagy, leading to the inhibition of the NLRP3 inflammasome. Uncoupling protein 2-reactive oxygen species signaling may be involved in inflammasome suppression by VitD3. Importantly, VitD3 had both preventive and therapeutic effects on mouse model of ulcerative colitis, via inhibition of NLRP3 inflammasome activation. Our results reveal a mechanism through which VitD3 represses inflammation and prevents the relevant diseases, and suggest a potential clinical use of VitD3 in autoimmune syndromes or other NLRP3 inflammasome-driven inflammatory diseases. ©2020 Society for Leukocyte Biology.BACKGROUND The importance of capturing and reporting health-related quality of life (HRQOL) in clinical trials has been increasingly recognized in the oncology field. As a result, the National Cancer Institute (NCI) began to provide support for correlative HRQOL studies in cancer treatment trials. The current study was conducted to assess the publication rate of HRQOL correlative studies in NCI-supported treatment trials and to identify potential factors positively or negatively associated with publication rates. METHODS The NCI conducted a retrospective review of existing NCI databases to identify cancer treatment trials that had obtained additional NCI funding for the assessment of HRQOL and to determine the extent to which funded HRQOL studies have been completed and published in a peer-reviewed journal. RESULTS Of the 108 included trials, 58 (54%) had a parent trial (PT) publication; of these, 36 trials (62%) had a published HRQOL result 20 as an independent publication and 16 that were included and/or reported in the PT publication. The length of time between trial activation and closure, as well as the specific cancer, appeared to be associated with the publication rates. CONCLUSIONS The results of the current study demonstrated that approximately 45% of the PT publications were followed by a HRQOL publication within 1 year, to allow the knowledge to be used in patient treatment decision making. The authors believe the current analysis is an important first step toward a better understand of the challenges that researchers face when reporting HRQOL endpoints. © 2020 American Cancer Society.KEY POINTS Spinal cord dorsal horn srGAP3 increases in the initiation phase of neuropathic pain and decreases in the maintenance phase. However, Rac1 activity which can be reduced by srGAP3, decreased in the initiation phase and increased in the maintenance phase. The increased srGAP3 in the initiation phase promotes new immature dendritic spines instigating neuropathic pain. Decreased srGAP3 in the maintenance phase enhances Rac1 activity facilitating maturation of dendritic spines and the persistence of neuropathic pain. srGAP3 siRNA can ameliorate neuropathic pain only when administrated in the initiation phase. The Rac1 inhibitor can ameliorate neuropathic pain only when administrated in the maintenance phase. Combined targeting of srGAP3 in the initiation phase and Rac1 in the maintenance phase can produce optimal analgesic efficacy. ABSTRACT Neuropathic pain includes an initiation phase and maintenance phase, each with different pathophysiological processes.
