Preparing for Success: Neural Frontal Theta and Posterior Alpha Dynamics during Action Preparation Predict Flexible Resolution of Cognitive Conflicts

Abstract Cognitive conflicts typically arise in situations that call for sudden changes in our behavior. Resolving cognitive conflicts is challenging and prone to errors. Humans can improve their chances to successfully resolve conflicts by mentally preparing for potential behavioral adjustments. Previous studies indicated that neural theta oscillations (4–7 Hz), as well as alpha oscillations (8–14 Hz), are reflective of cognitive control processes during conflict resolution. However, the role or neural oscillations for conflict preparation is still unclear. Therefore, the aim of the current study was to determine which oscillatory changes during conflict preparation predict subsequent resolution success. Participants performed a cued change-signal task, in which an anticipatory cue indicated if the upcoming trial might contain a cognitive conflict or not. Oscillatory activity was assessed via EEG. Cues that indicated that a conflict might arise compared with cues that indicated no conflict led to increases, directly followed by decreases, in theta power, as well as to decreases in alpha power. These cue-induced changes in theta and alpha oscillations occurred widespread across the cortex. Importantly, successful compared with failed conflict trials were characterized by selective increases in frontal theta power, as well as decreases in posterior alpha power during preparation. In addition, higher frontal theta power and lower posterior alpha power during preparation predicted faster conflict resolution. Our study shows that increases in frontal theta power, as well as decreases in posterior alpha power, are markers of optimal preparation for situations that necessitate flexible changes in behavior.
User Profiling System Using social Networks for Recommendation

In this paper, we propose a user profiling system using social networks for recommendation. Recent development of information technologies produces a lot of community services. SNS (Social Network Service) is one of the community services on the world wide webs. On the other hand, the recommendation algorithms arc one of the best known topics for their use on various kinds of web sites these days. The purpose of the proposed system is the web contents recommendation to users in social network services. The main idea of the proposed system is the interpolation of profile data by the data of other users who are linked with the focused user. Thc proposed system is one of the contents delivery systems, which employs information filtering system. The proposed system consists of the following two stages; (1) Learning profile data; (2) Filtering contents by profile data, In the first stage, the profile data are learned with the behavior of the user and the profile data of the other users. When the learned profile data are used in the second stage, proper information are filtered.
Usefulness of a mobile phone application for respiratory rate measurement in adult patients.

AIMS Respiratory rate measurement is one of the core nursing skills for early detection of deterioration of a patient's condition. Nevertheless, it is sometimes bothersome to visually measure respiratory rate over 1 min. Respiratory rate measurement using a mobile phone application "RRate" has been reported to be accurate and completed in a short time. However, it has only been investigated in children. The aim of this study was to validate the "RRate" compared with the 1-min method in adult patients. METHODS This was a cross-sectional study in the setting of a nursing school. Videos of the movement of the thorax during respiration of adult patients were made. Nursing students watched these videos and measured respiratory rate with each method. Bland-Altman analysis was used to calculate bias and limits of agreement. The times taken for the measurements were compared using a t test. RESULTS A total of 59 nursing students participated. When compared to the reference measurement, the one measured using "RRate" and the one measured over 1 min showed a bias of 0.40 breaths per minute and 0.65 breaths per minute, limits of agreement of -2.86 to 3.67 breaths per minute and -2.11 to 3.41 breaths per minute, respectively. The mean measurement time for "RRate" was 22.8 s (95% CI 13.9-36.6), which was significantly shorter than the 65.8 s (95% CI 61.0-73.2) for the measurement over 1 min (p < .001). CONCLUSIONS Respiratory rate can be measured accurately in a shorter time using a mobile phone application in adult patients.
Point-of-care NT-proBNP monitoring for heart failure: observational feasibility study in primary care

Background Around one million individuals in the UK have heart failure (HF), a chronic disease that causes significant morbidity and mortality. N-terminal pro-B-type natriuretic peptide (NT-proBNP) monitoring could help improve the care of patients with HF in the community. Aim The aim of this study is to provide evidence to support the routine use of point-of-care (POC) NT-proBNP monitoring in primary care. Design & setting In this observational cohort study, the Roche Cobas h 232 POC device was used to measure NT-proBNP in 27 patients with HF at 0, 6, and 12 months, with a subset reanalysed in the laboratory for comparison. Method Data were analysed for within-person and between-person variability and concordance with laboratory readings using Passing–Bablok regression. GPs reported whether POC results impacted clinical decisionmaking, and patients indicated their willingness to participate in long-term cohort studies using the Likert acceptability scale. Results Within-person variability in POC NT-proBNP over 12 months was 881 pg/mL (95% confidence interval [CI] = 380 to 1382 pg/mL). Between-person variability was 1972 pg/mL (95% CI = 1,525 to 2791 pg/mL). Passing–Bablok regression showed no significant systematic difference between POC and laboratory measurements. Patients indicated a high level of acceptability, and GP decisionmaking was affected for at least one visit in a third of patients. Conclusion Within-person variability in POC NT-proBNP is around half of between-person variability, so detecting changes could be of use in HF management. High patient acceptability and impact on clinical decisionmaking warrant further investigation in a larger long-term cohort study.
Religious affiliation and philosophical and moral beliefs about vaccines: A longitudinal study

How do religious affiliation and beliefs shape vaccine attitudes and behaviors? This study examined the associations of attitudes and behaviors relevant to the flu, measles-mumps-rubella (MMR), and human-papillomavirus (HPV) vaccines with religious affiliations, as well as philosophical, spiritual, and moral beliefs. Respondents were 3005 adults from a probability-based, four-wave panel survey in the United States. Longitudinal structural equation modeling examined how religious affiliations and philosophical/moral beliefs shaped attitudes toward vaccines and actual vaccination. Stronger philosophical beliefs predicted more negative attitudes toward each vaccine and stronger moral beliefs more negative attitudes toward the HPV vaccine. Negative vaccine attitudes then predicted weaker intentions to encourage others to vaccinate and lower probability of receiving a vaccine. Theoretical and public health messaging implications are discussed.
Feasibility of parents promoting fruit-infused water to reduce preschool children’s sugar-sweetened beverage consumption

Background: Increasing water and decreasing sugar-sweetened beverage (SSB) consumption in preschoolers provide a strategy to reduce lifelong obesity risks. Aim: To determine feasibility/acceptability and examine preliminary findings of an innovative intervention for preschooler parents to promote fruit-infused water (FIW) to decrease SSB intake. Methods: Fourteen parents of preschoolers completed a pre-intervention survey, attended a presentation with a FIW demonstration/taste-testing, received pitchers/strainers, cutting boards, and FIW recipes/instructions, and received 8 supportive text messages over one month. Feasibility/acceptability was determined from analyzing parents’ responses about participating. Descriptive statistics were conducted to analyze pre-/post-intervention survey data. Results: Three themes emerged: “Healthy Option Alternative”; “Feasible to Make FIW at Home”; and “Benefits for Parents”. Preliminary findings from ten parents completing both pre-/post-intervention surveys indicated a decrease in preschoolers’ total SSB amount/kcal intake, and an increase in parent self-efficacy and FIW knowledge/consumption. Conclusion: Preliminary findings provide valuable feasibility/acceptability information to guide a larger future study
Remote learning developments in postgraduate medical education in response to the COVID-19 pandemic – A BEME systematic review: BEME Guide No. 71

Abstract Background Prior reviews investigated medical education developments in response to COVID-19, identifying the pivot to remote learning as a key area for future investigation. This review synthesized online learning developments aimed at replacing previously face-to-face ‘classroom’ activities for postgraduate learners. Methods Four online databases (CINAHL, Embase, PsychINFO, and PubMed) and MedEdPublish were searched through 21 December 2020. Two authors independently screened titles, abstracts and full texts, performed data extraction, and assessed risk of bias. The PICRAT technology integration framework was applied to examine how teachers integrated and learners engaged with technology. A descriptive synthesis and outcomes were reported. A thematic analysis explored limitations and lessons learned. Results Fifty-one publications were included. Fifteen collaborations were featured, including international partnerships and national networks of program directors. Thirty-nine developments described pivots of existing educational offerings online and twelve described new developments. Most interventions included synchronous activities (n Fif5). Virtual engagement was promoted through chat, virtual whiteboards, polling, and breakouts. Teacher’s use of technology largely replaced traditional practice. Student engagement was largely interactive. Underpinning theories were uncommon. Quality assessments revealed moderate to high risk of bias in study reporting and methodology. Forty-five developments assessed reaction; twenty-five attitudes, knowledge or skills; and two behavior. Outcomes were markedly positive. Eighteen publications reported social media or other outcomes, including reach, engagement, and participation. Limitations included loss of social interactions, lack of hands-on experiences, challenges with technology and issues with study design. Lessons learned highlighted the flexibility of online learning, as well as practical advice to optimize the online environment. Conclusions This review offers guidance to educators attempting to optimize learning in a post-pandemic world. Future developments would benefit from leveraging collaborations, considering technology integration frameworks, underpinning developments with theory, exploring additional outcomes, and designing and reporting developments in a manner that supports replication.
Considerations on the α-Factor of Nonideal, External Optical Mach- Zehnder Modulators

The α-factor (relation of chirp and amplitude modulation) of nonideal, external optical Mach-Zehnder modulators is reviewed and discussed. Depending on the modulator design, especially the crystal cut and the electrode configuration and on the operation of the modulator the α-factor varies considerably. The absolute value of α can be determined by measuring the phase modulation power spectrum at a selected bias-point. The modulator type and its operation have to be chosen carefully for optimum performance in high-speed dispersive transmission systems.
Identification of hub genes and potential biomarkers of neutrophilic asthma: evidence from a bioinformatics analysis

Abstract Objective Asthma is a chronic airway inflammatory disease caused by multiple genetic and environmental factors. This study mainly sought to provide potential therapeutic targets and biomarkers for neutrophilic asthma (NA). Methods Three gene expression profiling datasets were obtained from the Genome Expression Omnibus (GEO) database. GSE45111 and GSE41863 were used to identify hub genes and potential biomarkers, and GSE137268 was used for data verification. We verified the repeatability of intragroup data and identified differentially expressed genes (DEGs). Then, we conducted Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses of the DEGs, and a protein–protein interaction (PPI) network was constructed to identify the hub genes. Finally, receiver operating characteristic (ROC) analysis was used to verify the ability of the hub genes to differentiate between NA and eosinophilic asthma (EA). Results In this study, we identified 411 DEGs by comprehensive analysis of NA/EA patients and NA/healthy controls (HCs). Ten hub genes (CXCR1, FCGR3B, CXCR2, SELL, S100A12, CSF3R, IL6R, JAK3, CD48, and GNG2) were identified from the PPI network. Finally, based on the ROC analysis, 7 genes showed good diagnostic value for discriminating NA from EA—CXCR1, FCGR3B, CXCR2, SELL, S100A12, CSF3R, and IL6R (AUC > 0.7). Conclusion We identified 7 hub genes that can distinguish NA from EA. The IL-8-mediated signaling may be the primary pathway to determine the NA phenotype in asthma. CXCR1/2 and S100A12 may be the primary genes determining the NA phenotype. CXCR1/2 and S100A12 might be biomarkers and new therapeutic targets for NA.

Group composition of individual personalities alters social network structure in experimental populations of forked fungus beetles

Social network structure is a critical group character that mediates the flow of information, pathogens and resources among individuals in a population, yet little is known about what shapes social structures. In this study, we experimentally tested whether social network structure depends on the personalities of individual group members. Replicate groups of forked fungus beetles (Bolitotherus cornutus) were engineered to include only members previously assessed as either more social or less social. We found that individuals expressed consistent personalities across social contexts, exhibiting repeatable numbers of interactions and numbers of partners. Groups composed of more social individuals formed networks with higher interaction rates, higher tie density, higher global clustering and shorter average shortest paths than those composed of less social individuals. We highlight group composition of personalities as a source of variance in group traits and a potential mechanism by which networks could evolve.
A Humanized Monoclonal Antibody Potentiates Killing of Diverse Biofilm-Forming Respiratory Tract Pathogens by Antibiotics

New strategies to treat diseases in which biofilms contribute significantly to pathogenesis are needed, as biofilm-resident bacteria are highly recalcitrant to antibiotics due to physical biofilm architecture and a canonically quiescent metabolism, among many additional attributes. We, and others, have shown that when biofilms are dispersed or disrupted, bacteria released from biofilm residence are in a distinct physiologic state that, in part, renders these bacteria highly sensitive to killing by specific antibiotics. ABSTRACT New strategies to treat diseases in which biofilms contribute significantly to pathogenesis are needed, as biofilm-resident bacteria are highly recalcitrant to antibiotics due to physical biofilm architecture and a canonically quiescent metabolism, among many additional attributes. We, and others, have shown that when biofilms are dispersed or disrupted, bacteria released from biofilm residence are in a distinct physiologic state that, in part, renders these bacteria highly sensitive to killing by specific antibiotics. We sought to demonstrate the breadth of the ability of a recently humanized monoclonal antibody against an essential biofilm structural element (DNABII protein) to disrupt biofilms formed by respiratory tract pathogens and potentiate antibiotic-mediated killing of bacteria released from biofilm residence. Biofilms formed by six respiratory tract pathogens were significantly disrupted by the humanized monoclonal antibody in a dose- and time-dependent manner, as corroborated by confocal laser scanning microscopy (CLSM) imaging. Bacteria newly released from the biofilms of 3 of 6 species were significantly more sensitive than their planktonic counterparts to killing by 2 of 3 antibiotics currently used clinically and were now also equally as sensitive to killing by the 3rd antibiotic. The remaining 3 pathogens were significantly more susceptible to killing by all 3 antibiotics. A humanized monoclonal antibody directed against protective epitopes of a DNABII protein effectively released six diverse respiratory tract pathogens from biofilm residence in a phenotypic state that was now as, or significantly more, sensitive to killing by three antibiotics currently indicated for use clinically. These data support this targeted, combinatorial, species-agnostic therapy to mitigate chronic bacterial diseases.
Development of an Anti-Acinetobacter baumannii Biofilm Phage Cocktail: Genomic Adaptation to the Host

The need for alternatives to antibiotic therapy due to the emergence of multidrug resistant bacteria (MDR), such as the nosocomial pathogen Acinetobacter baumannii, has led to the recovery of phage therapy. In addition, phages can be combined in cocktails to increase the host range. ABSTRACT The need for alternatives to antibiotic therapy due to the emergence of multidrug resistant bacteria (MDR), such as the nosocomial pathogen Acinetobacter baumannii, has led to the recovery of phage therapy. In addition, phages can be combined in cocktails to increase the host range. In this study, the evolutionary mechanism of adaptation was utilized in order to develop a phage adapted to A. baumannii, named phage Ab105-2phiΔCI404ad, from a mutant lytic phage, Ab105-2phiΔCI, previously developed by our group. The whole genome sequence of phage Ab105-2phiΔCI404ad was determined, showing that four genomic rearrangements events occurred in the tail morphogenesis module affecting the ORFs encoding the host receptor binding sites. As a consequence of the genomic rearrangements, 10 ORFs were lost and four new ORFs were obtained, all encoding tail proteins; two inverted regions were also derived from these events. The adaptation process increased the host range of the adapted phage by almost 3-fold. In addition, a depolymerase-expressing phenotype, indicated by formation of a halo, which was not observed in the ancestral phage, was obtained in 81% of the infected strains. A phage cocktail was formed by combining this phage with the A. baumannii phage vB_AbaP_B3, known to express a depolymerase. Both the individual phages and the phage cocktail showed strong antimicrobial activity against 5 clinical strains and 1 reference strain of A. baumannii tested. However, in all cases resistance to the bacterial strains was also observed. The antibiofilm activity of the individual phages and the cocktail was assayed. The phage cocktail displayed strong antibiofilm activity.
Conserved Proline Residues of Bacillus subtilis Intramembrane Metalloprotease SpoIVFB Are Important for Substrate Interaction and Cleavage

Intramembrane metalloproteases (IMMPs) function in numerous signaling pathways. Bacterial IMMPs govern stress responses, including the sporulation of some species, thus enhancing the virulence and persistence of pathogens. ABSTRACT Intramembrane metalloproteases (IMMPs) regulate diverse biological processes by cleaving membrane-associated substrates within the membrane or near its surface. SpoIVFB is an intramembrane metalloprotease of Bacillus subtilis that cleaves Pro-σK during endosporulation. Intramembrane metalloproteases have a broadly conserved NPDG motif, which in the structure of an archaeal enzyme is located in a short loop that interrupts a transmembrane segment facing the active site. The aspartate residue of the NPDG motif acts as a ligand of the zinc ion involved in catalysis. The functions of other residues in the short loop are less well understood. We found that the predicted short loop of SpoIVFB contains two highly conserved proline residues, P132 of the NPDG motif and P135. Mutational analysis revealed that both proline residues are important for Pro-σK cleavage in Escherichia coli engineered to synthesize the proteins. Substitutions for either residue also impaired the Pro-σK interaction with SpoIVFB in copurification assays. Disulfide cross-linking experiments showed that the predicted short loop of SpoIVFB is in proximity to the N-terminal pro-sequence region (Proregion) of Pro-σK. Alanine substitutions for N129 and P132 of the SpoIVFB NPDG motif reduced cross-linking between its predicted short loop and the Proregion more than a P135A substitution. Conversely, the SpoIVFB P135A substitution reduced Pro-σK cleavage more than the N129A and P132A substitutions during sporulation of B. subtilis. We conclude that all three conserved residues of SpoIVFB are important for substrate interaction and cleavage, and we propose that P135 is necessary to position D137 to act as a zinc ligand. IMPORTANCE Intramembrane metalloproteases (IMMPs) function in numerous signaling pathways. Bacterial IMMPs govern stress responses, including the sporulation of some species, thus enhancing the virulence and persistence of pathogens. Knowledge of IMMP-substrate interactions could aid therapeutic design, but structures of IMMP·substrate complexes are unknown. We examined the interaction of the IMMP SpoIVFB with its substrate Pro-σK, whose cleavage is required for Bacillus subtilis endosporulation. We found that conserved proline residues in a short loop predicted to interrupt a SpoIVFB transmembrane segment are important for Pro-σK binding and cleavage. The corresponding residues of the Escherichia coli IMMP RseP have also been shown to be important for substrate interaction and cleavage, suggesting that this is a broadly conserved feature of IMMPs, potentially suitable as a therapeutic target.
Biorefineries – factories of the future

Efforts were made to demonstrate that in biorefineries it is possible to manufacture all the commodities required for maintaining human civilisation on the current level. Biorefineries are based on processing biomass resulting from photosynthesis. From sugars, oils and proteins, a variety of food, feed, nutrients, pharmaceuticals, polymers, chemicals and fuels can further be produced. Production in biorefineries must be based on a few rules to fulfil sustainable development: all raw materials are derived from biomass, all products are biodegradable and production methods are in accordance with the principles of Green Chemistry and Clean Technology. The paper presents a summary of state-of-the-art concerning biorefineries, production methods and product range of leading companies in the world that are already implemented. Potential risks caused by the development of biorefineries, such as: insecurities of food and feed production, uncontrolled changes in global production profiles, monocultures, eutrophication, etc., were also highlighted in this paper. It was stressed that the sustainable development is not only an alternative point of view but is our condition to survive.
