Acute pericarditis has a wide spectrum of clinical presentations largely depending on underlying aetiologies. We assessed the role of age and sex in the clinical features and outcome of acute pericarditis.

A total of 240 consecutive patients hospitalized with a first episode of acute pericarditis were included. At baseline demographics, clinical features, laboratory and imaging findings and medical therapy were recorded. Patients were followed up for at least 18months for complications. Data comparisons were performed according to sex and age (≤60 or >60years).

The male/female ratio was 1.42, and 56% of patients were >60years. Younger patients depicted more often chest pain (P=.001), fever and rubs (P<.001 for both), ST elevation and PR depression (P=.032 and .009, respectively), higher CRP values (P=.009) and less often dyspnoea (P=.046) and pericardial effusion (P=.036). Moreover, they received less often glucocorticoids (P<.001) and depicted less atrial fibrillation (P=.003) and a higher rate of recurrent pericarditis (P=.013). After multivariate adjustment for confounders, age >60years remained an independent predictor for a lower risk of recurrent pericarditis (hazard ratio 0.60, 95% CI 0.39-0.96, P=.033). Regarding sex, females were older (P=.007), showed less often ST elevation and PR depression (P<.001 and .002, respectively) and had a higher baseline heart rate (P=.02). Sex was not associated with recurrent pericarditis risk.

Patients with acute pericarditis have distinct presenting clinical, biochemical and prognostic features according to age and sex. Awareness of such differences is important for clinical decision-making.

In this study, 80% waxy or normal HLB wholegrain flour (WGF) and 20% wheat flour were used for baking bread. ABBV-2222 molecular weight The farinograph and pasting properties of composite powders, and the nutritional value, textural properties, and in vitro hydrolysis of resultant breads were evaluated. The addition of a high proportion of HLB WGFs significantly increased the nutritional value of breads, especially the β-glucan contents of waxy HLB breads. The addition of HLB WGFs and a suitable amount of wheat gluten led to a lower degree of softening of HLB bread flours but improved its farinograph characteristics, such as higher water absorption rate, development time, stability time, and farinograph quality number. Although the sensory profiles of HLB breads were considerably lower than those of wheat bread, they still received a good overall acceptability fe. Therefore, a high proportion of hull-less barley could be recommended for bread production.In recent years, hydrocolloids have been used extensively as enhancers in dough products. However, studies on the effect of hydrophilic polymers on wheat gluten (WG) within the dough are scarce. In the present study, poly-γ-glutamic acid (γ-PGA), a new and healthy food additive, was added to the WG to investigate its effect on hydration, rheological properties, and structures of WG. Results showed that with the addition of γ-PGA, the water-holding capacity (WHC) of WG and the content of bound water increased, whereas the content of immobilized water decreased. In addition, γ-PGA changed the rheological properties of WG. The elastic properties of WG gradually weakened and the viscous properties gradually increased. Furthermore, scanning electron microscopy (SEM) results showed that with the addition of γ-PGA, the structure of the WG network became more uniform and the pore size was smaller. link2 A change also occurred in the secondary structure of WG, in which the α-helix content was significantly reduced while thets such as bread, seitan (meat replacement), and others.
MicroRNAs (miRNAs) are implicated in the epigenetic regulation of complex biological processes. Their possible role in human oral wound healing, a process that differs from cutaneous wound healing by being faster and typically scar-free, has been unexplored. This report presents the miRNA expression profile of experimental human oral wounds and an integrative analysis of mRNA/miRNA expression.

Nine healthy volunteers provided standardized normal and 5-day healing palatal biopsies, used for next generation miRNA and mRNA sequencing analysis, correlation and network analysis, real-time PCR (qPCR) and immunohistochemistry.

On average, 169 significantly regulated precursor miRNAs were detected, including 21 novel miRNAs, selectively confirmed by PCR. Hsa-miR-223-3p and hsa-miR-124-3p were, respectively, the most up- and downregulated miRNAs in healing gingiva. Hsa-miR-124-3p had the most predicted mRNA target interactions, with angiogenesis-related genes the most enriched. Correlation analysis showed the hi3 as potential wound healing therapeutic targets.
We performed a prospective electrostimulation study of the motor homunculus in 100 patients without motor deficit or brain lesion in the precentral gyrus in order to acquire accurate Montreal Neurological Institute (MNI) coordinates of the functional areas. The analysis of 248 body coordinates in the precentral gyrus showed rare inter-individual variations in the medial-to-lateral somatotopic movement organization with quite similar intensity thresholds. Electrostimulation only induced basic and stereotyped movements. We detected a relative medial-to-lateral somatotopy of the wrist/hand/global/individual fingers, with sometimes different sites for an individual muscle or movement. We found some similarities to, but also substantial differences from, the seminal work of Penfield and colleagues. We propose an updated version of the human motor homunculus and of its correlation with the somatosensory homunculus, previously defined in MNI space with a similar brain mapping technique.

In this prospective elect data to those previously obtained for the somatosensory homunculus.As an important economic crop in tropical areas, Areca catechu L. affects the livelihood of millions of farmers. The Areca yellow leaf phenomenon (AYLP) leads to severe crop losses and plant death. To better understand the relationship of microbes and chlorotic Areca leaves, microbial community structure as well as its correlation with differential metabolites was investigated by high-throughput sequencing and metabolomic approaches. High-throughput sequencing of the internal transcribed spacer 1 (ITS1) and 16S rRNA gene revealed that fungal diversity was dominated by Ascomycota and the bacterial community consisted of Proteobacteria as well as Actinobacteria. The microbiota structure on chlorotic Areca leaves exhibited significant changes based on non-metric multidimensional scaling (NMDS) analysis, which were attributed to 477 bacterial genera and 183 fungal genera. According to the results of the Kruskal-Wallis test, several potential pathogens were enriched on chlorotic Areca leaves. Further analysis based on metabolic pathways predicted by PICRUSt revealed the metabolism of half-yellow leaves and yellow leaves microbiota were significantly elevated in amino acid metabolism, carbohydrate metabolism, glycan biosynthesis and metabolism, metabolism of cofactors and vitamins, partial xenobiotics biodegradation and metabolism. Furthermore, 22 significantly variable metabolites in Areca leaves were identified by ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry (UPLC-Q/TOF-MS) and statistical analysis. Moreover, we further investigated the correlation between the predominant microbes and differential metabolites. Taken together, the association between AYLP and microbiome of Areca leaves was explored from the microecological perspective by omics techniques, and these findings provide new insights into possible prevention, monitoring and control of AYLP in the future.Theories predict that directional selection during adaptation to a novel habitat results in elevated meiotic recombination rate. Yet the lack of population-level recombination rate data leaves this hypothesis untested in natural populations. Here, we examine the population-level recombination rate variation in two incipient ecological species, the microcrustacean Daphnia pulex (an ephemeral-pond species) and Daphnia pulicaria (a permanent-lake species). The divergence of D. pulicaria from D. pulex involved habitat shifts from pond to lake habitats as well as strong local adaptation due to directional selection. Using a novel single-sperm genotyping approach, we estimated the male-specific recombination rate of two linkage groups in multiple populations of each species in common garden experiments and identified a significantly elevated recombination rate in D. pulicaria. Most importantly, population genetic analyses show that the divergence in recombination rate between these two species is most likely due to divergent selection in distinct ecological habitats rather than neutral evolution.Antimicrobial peptides are important players of the innate host defence against invading microorganisms. The aim of this study was to evaluate the activity of airway antimicrobial peptides against the common cystic fibrosis (CF) pathogen Pseudomonas aeruginosa, and to compare it to the emerging multi-drug resistant CF pathogens Achromobacter xylosoxidans and Stenotrophomonas maltophilia. Clinical bacterial isolates from CF patients were used, and the antimicrobial activity of human beta-defensin 2 and 3, LL37 and lysozyme was evaluated using radial diffusion assay and viable counts. The cell surface zeta potential was analysed to estimate the net charge at the bacterial surface. Of the bacterial species included in the study, A. xylosoxidans was the most resistant to antimicrobial peptides, whereas P. aeruginosa was the most susceptible. The net charge of the bacterial surface was significantly more negative for P. aeruginosa compared to A. xylosoxidans, which may in part explain the differences in susceptibility.Genomes are characterized by large regions of homogeneous base compositions known as isochores. The latter are divided into GC-poor and GC-rich classes linked to distinct functional and structural properties. Several studies have addressed how isochores shape function and structure. To aid in this important subject, we present IsoXpressor, a tool designed for the analysis of the functional property of transcription within isochores. IsoXpressor allows users to process RNA-Seq data in relation to the isochores, and it can be employed to investigate any biological question of interest for any species. The results presented herein as proof of concept are focused on the preimplantation process in Homo sapiens (human) and Macaca mulatta (rhesus monkey).FLASH radiotherapy delivers a high dose (≥10 Gy) at a high rate (≥40 Gy/s). In this way, particles are delivered in pulses as short as a few nanoseconds. At that rate, intertrack reactions between chemical species produced within the same pulse may affect the heterogeneous chemistry stage of water radiolysis. This stochastic process suits the capabilities of the Monte Carlo method, which can model intertrack effects to aid in radiobiology research, including the design and interpretation of experiments. In this work, the TOPAS-nBio Monte Carlo track-structure code was expanded to allow simulations of intertrack effects in the chemical stage of water radiolysis. link3 Simulation of the behavior of radiolytic yields over a long period of time (up to 50 s) was verified by simulating radiolysis in a Fricke dosimeter irradiated by 60Co γ rays. In addition, LET-dependent G values of protons delivered in single squared pulses of widths, 1 ns, 1 µs and 10 µs, were obtained and compared to simulations using no intertrack considerations.
