Automated Spatial Data Generalisation in Support of Diasters Response

A boot liner, preferably for use with a ski boot of the rear-entry type, including an exterior envelope and an interior sock, having an injection cavity therebetween. Within the injection cavity, a filling product is designed to be injected for retaining the foot of the skier within the boot liner and within the ski boot within which it is adapted to be used. The exterior envelope and the interior sock are sealed along a lower peripheral edge defining a sole portion of the boot liner. The peripheral edge is engageable within a peripheral groove in the internal wall of the exterior envelope to thereby seal the injection cavity from the sole portion of the boot liner to thereby prevent the filling product from flowing beneath the sole of the foot positioned within the boot liner. The injection cavity is defined by respective surfaces of the external envelope and the interior sock. The surface of the interior sock adjacent the cavity is coated with a anti-friction film which is micro-porous for permitting the escape of residual air within the cavity as the filling product is injected therein, while retaining the filling product. Further, the surface or the exterior envelope adjacent the cavity includes a plurality of peripheral ribs which direct the flow of the filling product from the injection orifice toward remote portions of the cavity. Maintenance means and foot retention means can be used in conjunction with the boot liner of the present invention.
Chimeric antigen receptors designed to overcome transforming growth factor‐β‐mediated repression in the adoptive T‐cell therapy of solid tumors

Adoptive cell therapy with chimeric antigen receptor (CAR)‐engineered T cells produced lasting remissions in the treatment of advanced, so far refractory B‐cell malignancies; however, the elimination of solid tumors remains so far elusive. The low efficacy of CAR T cells is thought to be due to the immune‐repressive milieu within the tumor lesion, predominantly mediated by transforming growth factor‐β (TGF‐β) that represses effector T‐cell activities and drives differentiation towards regulatory T cells (Tregs). Seeking to boost antitumor immunity, TGF‐β is currently targeted by different means in pre‐clinical studies. While a recent clinical trial showed the utility of shielding CAR T cells from TGF‐β repression, further strategies in counteracting TGF‐β in the adoptive cell therapy warrant exploration. We here discuss the most recent advances in the field and draw future developments to make CAR T‐cell therapy more potent in the treatment of solid cancer.
New microsatellites for the Atacama Desert endemic Balsamocarpon brevifolium (Fabaceae)

Premise Algarrobilla (Balsamocarpon brevifolium, Fabaceae) is an endemic xerophytic shrub restricted to the Atacama Desert in northern Chile. Extensive utilization of the region for coal production has endangered this species. Conservation efforts are underway, with genetic diversity analyses being key to the restoration of these populations. Methods and Results Fifteen new microsatellite markers were developed for B. brevifolium and used to analyze three populations from the Atacama and Coquimbo regions in Chile. Microsatellites were highly polymorphic, with an average of 5.77 alleles per marker and an average level of expected heterozygosity of 0.72. These markers were evaluated and cross‐amplified on two related species (Senna cumingii and Caesalpinia angulata) with partial success. Conclusions The development of this set of markers permits an extensive study of B. brevifolium populations for conservation purposes.
A Cross-Sectional Study of Stress and the Perceived Style of Decision-Making in Clinicians and Patients With Cancer

Background and Aims: Perceived stress and mindfulness can impact medical decision-making in both patients and clinicians. The aim of this study was to conduct a cross-sectional evaluation of the relationships between stress, mindfulness, self-regulation, perceptions of treatment conversations, and decision-making preferences among clinicians. Also, perceptions of treatment conversations and decision-making preferences among patients with cancer were evaluated. Methodology: Survey instruments were developed for clinicians and patients incorporating previously published questions and validated instruments. Institutional review board approval was obtained. Patients, physicians, and advanced practice providers from a tertiary referral center were asked to complete surveys. Continuous variables were evaluated for normality and then bivariate relationships between variables were evaluated using χ2, Fisher's exact test, Cochran-Mantel-Haenszel (CMH) row mean scores differ statistic, or Kruskal-Wallis tests, where appropriate. Significance was defined at P < . 05. All tests were conducted using SAS v.9. 4. Results: 77 patients and 86 clinicians (60.1% and 43% response rates, respectively) participated in the surveys. More clinicians who reported feeling “great/good” said they always/sometimes had enough time to spend with patients (66.1%) compared to those that hardly ever/never had enough time (26.3%), χ2(1, N = 75) = 6.62, P = . 0101; CMH row mean scores differ statistic). Interestingly, 40.3% of patients preferred a paternalistic style of decision-making compared to 6.3% of clinicians, χ2(2, N = 146) = 27.46, P < . 0001; χ2 test. Higher levels of dispositional mindfulness (Mindful Attention Awareness Scale) were found among clinicians who reported they felt “great/good” (median = 4.5) as compared to those who reported that they were “definitely stressed/stressed out” (3.3), χ2(2, N = 80) = 10.32, P = . 0057; Kruskal-Wallis test. Higher levels of emotional self-regulation (Emotional Regulation Questionnaire—Cognitive Reappraisal facet) were found among clinicians who reported they felt “great/good” (median = 31.0) compared to those who reported that they were “definitely stressed/stressed out” (20.0), χ2(2, N = 79) = 8.88, P = . 0118; Kruskal-Wallis test. Conclusion: In order to have meaningful conversations about treatment planning, an understanding of mental well-being and its relationship to decision-making preferences is crucial for both oncology patients and clinicians. Our results show that for clinicians, lower perceived stress was associated with higher levels of mindfulness (experiencing the present moment), emotional self-regulation, and spending more time with patients. Larger prospective studies are needed to validate these findings.
Development of EST‐SSR markers in Saxifraga sinomontana (Saxifragaceae) and cross‐amplification in three related species

Premise Saxifraga sinomontana (Saxifragaceae) is a widespread alpine species in the Qinghai–Tibetan Plateau and its flanking mountains. We developed a set of expressed sequence tag–simple sequence repeat (EST‐SSR) markers to investigate the genetic diversity and evolutionary history of the species. Methods and Results We initially designed 50 EST‐SSR markers based on transcriptome data of S. sinomontana. Nineteen of 50 loci (38%) were successfully amplified, 13 of which were polymorphic. These were tested on 71 individuals from four populations. Three to 18 alleles per locus were detected, and the levels of observed and expected heterozygosity ranged from 0.2817 to 0.9155 and 0.2585 to 0.8495, respectively. In addition, cross‐amplification was successful for all 13 loci in three congeneric species, S. tangutica, S. heleonastes, and S. congestiflora. Conclusions These EST‐SSR markers will be useful for studying the genetic diversity of S. sinomontana and disentangling the phylogenetic relationships of related species.
Sequential Changes in the Host Gut Microbiota During Infection With the Intestinal Parasitic Nematode Strongyloides venezuelensis

Soil-transmitted helminths (STHs) are medically important parasites that infect 1. 5 billion humans globally, causing a substantial disease burden. These parasites infect the gastrointestinal tract (GIT) of their host where they co-exist and interact with the host gut bacterial flora, leading to the coevolution of the parasites, microbiota, and host organisms. However, little is known about how these interactions change through time with the progression of infection. Strongyloidiasis is a human parasitic disease caused by the nematode Strongyloides stercoralis infecting 30–100 million people. In this study, we used a closely related rodent parasite Strongyloides venezuelensis and mice as a model of gastrointestinal parasite infection. We conducted a time-course experiment to examine changes in the fecal microbiota from the start of infection to parasite clearance. We found that bacterial taxa in the host intestinal microbiota changed significantly as the infection progressed, with an increase in the genera Bacteroides and Candidatus Arthromitus, and a decrease in Prevotella and Rikenellaceae. However, the microbiota recovered to the pre-infective state after parasite clearance from the host, suggesting that these perturbations are reversible. Microarray analysis revealed that this microbiota transition is likely to correspond with the host immune response. These findings give us an insight into the dynamics of parasite-microbiota interactions in the host gut during parasite infection.
Cross-Species Genome-Wide Analysis Reveals Molecular and Functional Diversity of the Unconventional Interferon-ω Subtype

Innate immune interferons (IFNs), particularly type I IFNs, are primary mediators regulating animal antiviral, antitumor, and cell-proliferative activity. These antiviral cytokines have evolved remarkable molecular and functional diversity to confront ever-evolving viral threats and physiological regulation. We have annotated IFN gene families across 110 animal genomes, and showed that IFN genes, after originating in jawed fishes, had several significant evolutionary surges in vertebrate species of amphibians, bats and ungulates, particularly pigs and cattle. For example, pigs have the largest but still expanding type I IFN family consisting of nearly 60 IFN-coding genes that encode seven IFN subtypes including multigene subtypes of IFN-α, -δ, and -ω. Whereas, subtypes such as IFN-α and -β have been widely studied in many species, the unconventional subtypes such as IFN-ω have barely been investigated. We have cross-species defined the IFN evolution, and shown that unconventional IFN subtypes particularly the IFN-ω subtype have evolved several novel features including: (1) being a signature multi-gene subtype expanding primarily in mammals such as bats and ungulates, (2) emerging isoforms that have superior antiviral potency than typical IFN-α, (3) highly cross-species antiviral (but little anti-proliferative) activity exerted in cells of humans and other mammalian species, and (4) demonstrating potential novel molecular and functional properties. This study focused on IFN-ω to investigate the immunogenetic evolution and functional diversity of unconventional IFN subtypes, which may further IFN-based novel antiviral design pertinent to their cross-species high antiviral and novel activities.
The Signal Transduction Protein PII Controls Ammonium, Nitrate and Urea Uptake in Cyanobacteria

PII signal transduction proteins are widely spread among all domains of life where they regulate a multitude of carbon and nitrogen metabolism related processes. Non-diazotrophic cyanobacteria can utilize a high variety of organic and inorganic nitrogen sources. In recent years, several physiological studies indicated an involvement of the cyanobacterial PII protein in regulation of ammonium, nitrate/nitrite, and cyanate uptake. However, direct interaction of PII has not been demonstrated so far. In this study, we used biochemical, molecular genetic and physiological approaches to demonstrate that PII regulates all relevant nitrogen uptake systems in Synechocystis sp. strain PCC 6803: PII controls ammonium uptake by interacting with the Amt1 ammonium permease, probably similar to the known regulation of E. coli ammonium permease AmtB by the PII homolog GlnK. We could further clarify that PII mediates the ammonium- and dark-induced inhibition of nitrate uptake by interacting with the NrtC and NrtD subunits of the nitrate/nitrite transporter NrtABCD. We further identified the ABC-type urea transporter UrtABCDE as novel PII target. PII interacts with the UrtE subunit without involving the standard interaction surface of PII interactions. The deregulation of urea uptake in a PII deletion mutant causes ammonium excretion when urea is provided as nitrogen source. Furthermore, the urea hydrolyzing urease enzyme complex appears to be coupled to urea uptake. Overall, this study underlines the great importance of the PII signal transduction protein in the regulation of nitrogen utilization in cyanobacteria.
Genetic Diversity, Virulence, Race Profiling, and Comparative Genomic Analysis of the Fusarium oxysporum f. sp. conglutinans Strains Infecting Cabbages in China

Cabbage Fusarium wilt (CFW) caused by Fusarium oxysporum f. sp. conglutinans (FOC) is known to significantly affect yield and quality of cabbages worldwide. CFW was first detected in New York, NY, United States, and has now spread to almost all cabbage-planting areas, including a recent outbreak of the disease in China. However, it was unknown whether the FOC strains emerged in China differed from the strains in other areas of the world. From 2009 to 2018, we collected Chinese FOC isolates and compared them to the races 1 and 2 strains in other areas to define their characteristics. Race tests indicated that most of the Chinese FOC strains belonged to race 1 and were more virulent than type strain 52557. To evaluate the genome level diversity, we performed next-generation sequencing and genome assembly for the race 2 strain 58385. Based on the assembled genome, we discovered abundant single-nucleotide polymorphisms and 645 insertion–deletions (InDels) compared with the race 1 strain FGL03-6 by comparative genomic analysis and showed that all FOC race 1 strains have a low genetic variability, with a genomic background distinct from 58385. Furthermore, the internal transcribed spacer, elongation factor-1α, and whole-genome InDel variation studies suggested that the last might be a powerful tool in phylogenetic as well as evolution analysis for F. oxysporum Schlechtend. : Fr. The race, virulence, and genome-based variation profiles could contribute to our knowledge of FOC diversity and support the studies of pathogen characterization in genomic era and also provide clues for CFW-resistance breeding. To our knowledge, this is the first extensive survey conducted for FOC strains.
Mechanisms of ROS Regulation of Plant Development and Stress Responses

Plants are subjected to various environmental stresses throughout their life cycle. Reactive oxygen species (ROS) play important roles in maintaining normal plant growth, and improving their tolerance to stress. This review describes the production and removal of ROS in plants, summarizes recent progress in understanding the role of ROS during plant vegetative apical meristem development, organogenesis, and abiotic stress responses, and some novel findings in recent years are discussed. More importantly, interplay between ROS and epigenetic modifications in regulating gene expression is specifically discussed. To summarize, plants integrate ROS with genetic, epigenetic, hormones and external signals to promote development and environmental adaptation.
Dissemination of Multidrug-Resistant Commensal Escherichia coli in Feedlot Lambs in Southeastern Brazil

Antimicrobial resistance (AR) is a public health issue since it limits the choices to treat infections by Escherichia coli in humans and animals. In Brazil, the ovine meat market has grown in recent years, but studies about AR in sheep are still scarce. Thus, this study aims to investigate the presence of AR in E. coli isolated from lambs during feedlot. To this end, feces from 112 lambs with 2 months of age, after weaning, were collected on the first day of the animals in the feedlot (day 0), and on the last day before slaughtering (day 42). Isolates were selected in MacConkey agar supplemented with 4 mg/L of ceftiofur and identified by biochemical methods. Isolates were submitted to an antimicrobial susceptibility test by disc-diffusion and PCR to investigate genes for phylogenetic group, virulence determinants and resistance to the several antimicrobial classes tested. The genetic localization of the bla genes detected was elucidated by S1-PFGE followed by Southern blot-hybridizations. The isolates were typed by XbaI-PFGE and MLST methods. Seventy-eight E. coli were isolated from 8/112 (7.1%) animals on day 0, and from 55/112 (49.1%) animals on day 42. Since only fimH was present in almost all E. coli (97.4%) as a virulence gene, and also 88.5% belonged to phylogroups B1 or A, we consider that isolates represent intestinal commensal bacteria. The dendrogram separated the 78 non-virulent isolates in seven clusters, two of which comprised 50 E. coli belonging to ST/CC 1727/446 or ST 3994 recovered on day 42 commonly harboring the genotype blaCMY -2-aac(3)-IIa -tetA-sul1-sul2-floR-cmlA. Special attention should be given to the presence of blaCTX-M-15, a worldwide gene spread, and blaCTX-M-14, a hitherto undetected gene in Enterobacteriaceae from food-producing animals in Brazil. Importantly, E. coli lineages and plasmids carrying bla genes detected here have already been reported as sources of infection in humans either from animals, food, or the environment, which raises public health concerns. Hence, two types of commensal E. coli carrying important AR genes clearly prevailed during feedlot, but lambs are also reservoirs of bacteria carrying important AR genes such as blaCTX-M-14 and blaCTX-M-15, mostly related to antimicrobial treatment failure.
Distinct Spatio-Temporal Dynamics of Tumor-Associated Neutrophils in Small Tumor Lesions

Across a majority of cancer types tumor-associated neutrophils (TAN) are linked with poor prognosis. However, the underlying mechanisms, especially the intratumoral behavior of TAN, are largely unknown. Using intravital multiphoton imaging on a mouse model with neutrophil-specific fluorescence, we measured the migration of TAN in distinct compartments of solid tumor cell lesions in vivo. By longitudinally quantifying the infiltration and persistence of TAN into growing tumors in the same animals, we observed cells that either populated the peripheral stromal zone of the tumor (peritumoral TAN) or infiltrated into the tumor core (intratumoral TAN). Intratumoral TAN showed prolonged tumor-associated persistence and reduced motility compared to peritumoral TAN, whose velocity increased with tumor progression. Selective pharmacological blockade of CXCR2 receptors using AZD5069 profoundly inhibited recruitment of TAN into peritumoral regions, while intratumoral infiltration was only transiently attenuated and rebounded at later time points. Our findings unravel distinct spatial dynamics of TAN that are partially and differentially regulated via the CXCR2 signaling pathway.
An NFκB Activity Calculator to Delineate Signaling Crosstalk: Type I and II Interferons Enhance NFκB via Distinct Mechanisms

Nuclear factor kappa B (NFκB) is a transcription factor that controls inflammation and cell survival. In clinical histology, elevated NFκB activity is a hallmark of poor prognosis in inflammatory disease and cancer, and may be the result of a combination of diverse micro-environmental constituents. While previous quantitative studies of NFκB focused on its signaling dynamics in single cells, we address here how multiple stimuli may combine to control tissue level NFκB activity. We present a novel, simplified model of NFκB (SiMoN) that functions as an NFκB activity calculator. We demonstrate its utility by exploring how type I and type II interferons modulate NFκB activity in macrophages. Whereas, type I IFNs potentiate NFκB activity by inhibiting translation of IκBα and by elevating viral RNA sensor (RIG-I) expression, type II IFN amplifies NFκB activity by increasing the degradation of free IκB through transcriptional induction of proteasomal cap components (PA28). Both cross-regulatory mechanisms amplify NFκB activation in response to weaker (viral) inducers, while responses to stronger (bacterial or cytokine) inducers remain largely unaffected. Our work demonstrates how the NFκB calculator can reveal distinct mechanisms of crosstalk on NFκB activity in interferon-containing microenvironments.
The Evolution of Prosocial and Antisocial Competitive Behavior and the Emergence of Prosocial and Antisocial Leadership Styles

Evolutionary analysis focuses on how genes build organisms with different strategies for engaging and solving life’s challenges of survival and reproduction. One of those challenges is competing with conspecifics for limited resources including reproductive opportunities. This article suggests that there is now good evidence for considering two dimensions of social competition. The first, has been labeled as antisocial strategies, to the extent that they tend to be self-focused, threat sensitive and aggressive, and use tactics of bulling, threatening, and intimidating subordinates, or even injuring/killing competitors. Such strategies can inhibit care and affiliative social interactions and motivation. The social signals emitted stimulate threat processing in recipients and can create stressed and highly stratified groups with a range of detrimental psychological and physiological effects. Second, in contrast, prosocial strategies seek to create relaxed and secure social interactions that enable sharing, cooperative, mutually supportive and beneficial relationships. The friendly and low/no threat social signals emitted in friendly cooperative and affiliative relationships stimulate physiological systems (e.g., oxytocin, the vagus nerve of the parasympathetic system) that downregulates threat processing, enhances the immune system, and facilitates frontal cortical processes and general wellbeing. This article reviews the literature pertaining to the evidence for these two dimensions of social engagement.
Twitter Response to Munich July 2016 Attack: Network Analysis of Influence

Social Media platforms in Cyberspace provide communication channels for individuals, businesses, as well as state and non-state actors (i.e., individuals and groups) to conduct messaging campaigns. What are the spheres of influence that arose around the keyword #Munich on Twitter following an active shooter event at a Munich shopping mall in July 2016? To answer that question in this work, we capture tweets utilizing #Munich beginning 1 h after the shooting was reported, and the data collection ends approximately 1 month later1. We construct both daily networks and a cumulative network from this data. We analyze community evolution using the standard Louvain algorithm, and how the communities change over time to study how they both encourage and discourage the effectiveness of an information messaging campaign. We conclude that the large communities observed in the early stage of the data disappear from the #Munich conversation within 7 days. The politically charged nature of many of these communities suggests their activity is migrated to other Twitter hashtags (i.e., conversation topics). Future analysis of Twitter activity might focus on tracking communities across topics and time.
