Extracellular vesicle-associated soluble CD163 and CD206 in patients with acute and chronic inflammatory liver disease

Abstract Background: Extracellular vesicles (EVs) are implicated in intercellular communication in liver diseases. An EV-associated fraction of the macrophage biomarker soluble CD163, denoted EV-CD163, was recently identified. EV-CD163 may be released during later phases of the inflammatory response as opposed to the acute shedding of CD163 ectodomain (Ecto-CD163). Total sCD163 is a well-described biomarker in liver inflammation, and we investigated the distribution of CD163 fractions along with EV-associated soluble CD206 (EV-CD206) in patients with acute and chronic alcoholic liver inflammation. Methods: Patients with acute alcoholic hepatitis (AH) (n = 48) and alcoholic cirrhosis (AC) (n = 26) were enrolled. Patients with AH were followed for 30 days after diagnosis. Healthy blood donors (n = 30) served as a reference group. Fractions of sCD163 and sCD206 were separated using ExoQuick™ and measured by ELISA. Results: We demonstrated a possible EV-associated fraction of CD206 in plasma, correlating with levels of EV-CD163 (rs = 0.46, p < .001). The distribution of biomarker fractions was skewed toward EVs in chronic cirrhosis for both biomarkers (median: 35.8% EV-CD163, 58.8% EV-CD206) as compared to AH patients (median: 26.2% EV-CD163 p < .0001, 48.8% EV-CD206, p < .01). In AH patients, total sCD163 and Ecto-CD163 at inclusion were related to survival, whereas EV-CD163 was not. Conclusion: Extracellular vesicles of macrophage origin associated with membrane receptors CD163 and CD206 are present in liver disease. We observed a shift in the distribution towards an increased EV fraction in chronic liver cirrhosis. These data support that Ecto and EV fractions may be markers of different inflammatory processes, possibly resulting from a switch in macrophage phenotype.

This article recounts the author’s personal views and recollections of the history, conception of embryogenetic theories, application of intraoperative electrophysiology, and development of prospective treatment recommendations of several important spinal dysraphic malformations, including limited dorsal myeloschisis, dermal sinus tract, retained medullary cord, terminal myelocystocoele, and complex spinal cord lipomas.
Pain characteristics and quality of life of breast cancer survivors that return and do not return to work: an exploratory cross-sectional study

Abstract Purpose the aim of this study is two-fold: 1) to explore the pain characteristics among breast cancer survivors that return to work and do not return to work; 2) to identify the factors associated with pain on the upper quadrant of the affected side. Materials and methods Sixty-two breast cancer survivors were included. Quality of life was assessed using EORTC QLQ-C30 and QLQ-BR23. Pain characteristics were assessed with a body diagram and a numeric rating scale. Results Thirty-five breast cancer survivors did not return to work. Ninety-one percent of women that did not return to work reported pain. The most frequent pain sites were the cervical spine and the axilla of the affected side. There were no significant differences in pain intensity between groups. The factors associated with pain on the upper quadrant of the affected side were perception of shoulder stiffness OR = 5.93 (1.38–44.87, 95%CI) and time since surgery of more than four years OR = 5.54 (1.36–20.97, 95% CI). Conclusions Pain was highly prevalent among breast cancer survivors. Breast cancer survivors that returned to work presented better quality of life. Longer time since surgery and perception of shoulder stiffness were associated with pain on the upper quadrant of the affected side. Implications for rehabilitation Pain is a major factor following breast cancer surgery preventing returning to work. This group reported more pain on the cervical spine and axilla of the affected side. Rehabilitation needs to focus specifically on pain management in order to improve quality of life. A multidisciplinary approach involving pain specialists and vocational support is recommended.
Curvature and Torsion of Protein Main Chain as Local Order Parameters of Protein Unfolding.

Thermal protein unfolding resembles a global (two-state) phase transition. At the local scale, protein unfolding is, however, heterogeneous and probe dependent. Here, we consider local order parameters defined by the local curvature and torsion of the protein main chain. Because chemical shift (CS) measured by NMR spectroscopy is extremely sensitive to the local atomic environment, CS has served as a local probe of thermal unfolding of proteins by varying the position of the atomic isotope along the amino-acid sequence. The variation of the CS of each Cα atom along the sequence as a function of the temperature defines a local heat-induced denaturation curve. We demonstrate that these local heat-induced denaturation curves mirror the local protein nativeness defined by the free-energy landscape of the local curvature and torsion of the protein main chain described by the Cα-Cα virtual bonds. Comparison between molecular dynamics simulations and CS data of the gpW protein demonstrates that some local native states defined by the local curvature and torsion of the main chain, mainly located in secondary structures, are coupled to each other whereas others, mainly located in flexible protein segments, are not. Consequently, CS of some residues are faithful reporters of global protein unfolding, with heat-induced denaturation curves similar to the average global one, whereas other residues remain silent about the protein unfolded state. For these latter, the local deformation of the protein main chain, characterized by its local curvature and torsion, is not cooperatively coupled to global unfolding.
Lurasidone in Children and Adolescents with Bipolar Depression Presenting with Mixed (Subsyndromal Hypomanic) Features: Post Hoc Analysis of a Randomized Placebo-Controlled Trial

Objectives: To evaluate the efficacy and safety of lurasidone in the treatment of children and adolescents with bipolar depression presenting with mixed (subsyndromal hypomanic) features. Methods: Patients, 10–17 years of age, with a Diagnostic and Statistical Manual of Mental Disorders, 5th ed. (DSM-5), diagnosis of bipolar I depression were randomized to 6 weeks of double-blind treatment with once-daily flexible doses of lurasidone 20–80 mg or placebo. The presence of mixed (subsyndromal hypomanic) features in this pediatric bipolar depression trial was defined as a Young Mania Rating Scale score of 5 or greater at study baseline. Key efficacy measures included change from baseline to week 6 in the Children's Depression Rating Scale-Revised (CDRS-R) score (primary endpoint) and Clinical Global Impressions-Bipolar Severity (CGI-BP-S) score, using a mixed model for repeated measures analysis. Results: At baseline, subsyndromal hypomanic features were present in 54.2% of patients. Treatment with lurasidone (vs. placebo) was associated with significantly greater reductions in CDRS-R scores at week 6, independent of the presence (−21.5 vs. −15.9, p < 0.01; effect size d = 0.43) or absence (−20.5 vs. −14.9, p < 0.01; d = 0.44) of subsyndromal hypomanic features. Likewise, lurasidone (vs. placebo) was associated with significantly greater reductions in CGI-BP-S scores at week 6, independent of the presence (−1.6 vs. −1.1, p < 0.001, d = 0.51) or absence (−1.3 vs. −1.0, p = 0.05; d = 0.31) of these subsyndromal hypomanic features. Rates of protocol-defined treatment-emergent hypomania or mania were similar for lurasidone and placebo in patients with (lurasidone 8.2% vs. placebo 9.0%) or without subsyndromal hypomanic features (lurasidone 1.3% vs. placebo 3.7%). Conclusions: In this post hoc analysis of a randomized placebo-controlled trial, lurasidone was found to be efficacious in the treatment of child and adolescent patients with bipolar depression who presented with mixed (subsyndromal hypomanic) features. No differences in safety profile, including the risk of treatment-emergent mania, were observed in patients with or without subsyndromal hypomanic features in this study.
Preanalytical variables that affect the outcome of cell-free DNA measurements

Abstract Fragments of cell-free DNA (cfDNA) in human body fluids often carry disease-specific alterations and are now widely recognized as ideal biomarkers for the detection and monitoring of genomic disorders, especially cancer, that are normally difficult to examine noninvasively. However, the conversion of promising research findings into tools useful in routine clinical testing of cancer has been a slow-moving process. A major reason is that the diagnostic sensitivity and specificity of cfDNA-based clinical assays are negatively impacted by a combination of suboptimal and inter-institutional differences in preanalytical procedures. The most prominent factors include: (i) a poor understanding of the biological factors that determine the characteristics of the cfDNA population in a biospecimen prior to collection, (ii) inattention to how cfDNA with different structures and physical properties are affected differently by a given preanalytical step, and (iii) the sheer number of possible conditions that can be selected from for each preanalytical step along with a continually expanding menu of commercial products that often show varying degrees of bias and efficiency. The convergence of these variables makes it difficult for research groups and institutions to reach a consensus on optimal preanalytical procedures and a challenging task to establish widely applied standards, which ultimately hamper the development of cfDNA assays that are fit for broad clinical implementation. In this review, we follow a systematic approach to explore the most confounding preanalytical factors that affect the outcome of cfDNA measurements.
Plant Growth-Promoting Bacteria from Solarized Soil with the Ability to Protect Melon Against Root Rot and Vine Decline Caused by Monosporascus cannonballus

AbstractThis study was undertaken to isolate indigenous plant growth-promoting(PGP) bacteria from solarized soil effective in the biocontrol of Monosporas-cus cannonballus, the cause of root rot and vine decline of melon, which isone of the most destructive soilborne diseases of this crop worldwide. Thescreening strategy resulted in the selection of two interesting PGP bacteriaas biocontrol candidates against M. cannonballus belonging to the samemicrobial community. The two bacterial species, identiﬁed according tophenotypic, physiological tests and analysis of the 16S rDNA sequence asBacillus subtilis/amyloliquefaciens (BsCR) and Pseudomonas putida (PpF4),showed PGP traits and in vitro antagonistic activity towards M. cannonbal-lus. Antagonism by BsCR was characterized by a consistent inhibition ofthe pathogen in vitro growth; PpF4 strongly inhibited the development ofperithecia of the pathogen. Under greenhouse conditions, the selectedbacteria were tested for their biocontrol activity in the pathosystemmelon-M. cannonballus. BsCR alone and in combination with PpF4 deter-mined a consistent decrease in the disease symptoms. BsCR and the com-bination of the bacterial strains signiﬁcantly increased root biomass inboth inoculated and un-inoculated plant. Upon seed treatment withBsCR, the accumulation and isoenzyme induction of peroxidase in rootsas biochemical marker for induction of resistance were found, thus indi-cating that BsCR may reduce the disease severity also by the activation ofthe plant defence responses. The study highlights the synergistic biocon-trol potential of B. subtilis BsCR and P. putida PpF4 in the integrated man-agement of root rot and vine decline of melon caused by M. cannonballus.IntroductionMonosporascus root rot and vine decline of meloncaused by the soilborne fungal pathogen Monosporas-cus cannonballus Pollak and Uecker is one of the mostdestructive soilborne diseases of this crop worldwide(Martyn and Miller 1996; Cohen et al. 2012) andprominent in several melon-producing areas in Italy(Chilosi et al. 2008). Symptoms of the disease arelocalized on the root system, represented by lesions,rots and loss of smaller feeder roots, resulting in wiltof plants prior to harvest, premature fruit ripeningand low sugar content of fruits. Although wilting anddeath are manifested in the late growing season, theonset of melon root infection can occur during theearly growth stages (Stanghellini et al. 2004). Mono-sporascus cannonballus produces distinctive ascosporesin fertile perithecia within the host roots. Ascosporesfunction as the only known survival structures andinoculum for root infection (Stanghellini et al. 2000).
Nutritional and physicochemical characteristics of purple sweet corn juice before and after boiling

Sweet corn juice is becoming increasingly popular in China. In order to provide valuable health-related information to consumers, the nutritional and physicochemical characteristics of raw and boiled purple sweet corn juices were herein investigated. Sugars, antinutrients, total free phenols, anthocyanins, and antioxidant activity were analyzed by conventional chemical methods. The viscosity and stability of juices were determined by Ubbelohde viscosity meter and centrifugation, respectively. Boiling process could elevate viscosity, stability and sugar content, and reduce antinutrients, total free phenols, anthocyanins, and antioxidant activity in corn juice. In addition, short time boiling efficiently reduced the degradation of anthocyanins during subsequent refrigeration. The content of amino acids, vitamin B1/B2 and E were detected by High Performance Liquid Chromatography. Gas Chromatography Mass Spectrometry was used for the analysis of fatty acids and aroma compounds. Several aroma compounds not previously reported in corn were identified, including 1-heptanol, 2-methyl-2-butenal, (Z)-3-nonen-1-ol, 3-ethyl-2-methyl-1,3-hexadiene, and 2,4-bis(1,1-dimethylethyl)phenol. Interestingly, the boiling process had no apparent effect on the amino acids profile, but it caused a 45.8% loss of fatty acids in the juice by promoting the retention of fatty acids in the corn residue. These results provide detailed information that could be used for increasing consumers’ knowledge of sweet corn juice, further development of sweet corn juice by food producers, and maize breeding programs.
Radiation-induced augmentation in dendritic cell function is mediated by apoptotic bodies/STAT5/Zbtb46 signaling

Abstract Purpose: To evaluate the effect of ionizing radiation (IR) exposure on differentiation and maturation of dendritic cells (DC). Materials and methods: Bone marrow progenitor cells irradiated in vitro or isolated from mice exposed to whole body or localized tumor irradiation were differentiated into DC. Phenotypic maturation of DC was characterized by labeling with specific antibodies and flow cytometry analysis. Cytokines were estimated by ELISA. Results: Splenic and bone marrow-derived DC (BMDC) from tumor-bearing mice exposed to localized irradiation showed abrogation of tumor-induced immunosuppression. This was not due to the effect of radiation on tumor cells as DC derived from normal mice exposed to whole-body irradiation (WBI) also showed increase in immune-activating potential of DC. This was observed in terms of increased phenotypic and functional activation of DCs. This phenomenon was also recapitulated if DC were differentiated from in vitro irradiated progenitor cells and was found to be due to STAT5/Zbtb46 signaling mediated by the irradiation-induced apoptotic bodies (ABs). When these ABs were depleted using annexin-beads, these effects were reversed confirming the involvement of this pathway. The role of ABs was further validated in DC derived from mice exposed to WBI in adaptive response experiments with 0.1 Gy priming dose prior to 2 Gy challenge dose. A corresponding reduction in DC maturation markers was observed with decrease in apoptosis in vivo. Further, these DCs derived from irradiated progenitors (IP) could resist the suppressive effects of tumor conditioned medium (TCM) and had increased immune-activating potential as seen in the tumor-bearing mice. Conclusions: Though radiation is the most commonly used therapeutic modality for cancer, its effects on dendritic cell differentiation is not completely understood. We demonstrate here for the first time that exposure to select doses of IR can increase immune-activating potential of DC through ABs. This can have implications in selection of appropriate doses of IR during radiotherapy of cancer patients.
Roles of HOTAIR in lung cancer susceptibility and prognosis

Long noncoding (lncRNA) single‐nucleotide polymorphisms (SNPs) are associated with the susceptibility to the development of various malignant tumors. The aim of this study was to investigate the roles of HOX transcript antisense intergenic RNA (HOTAIR) and its SNPs in lung cancer.
Variation of plastic responses to oxygen availability within the hybridogenetic Rana esculenta complex

The hypothesis of superiority of hybrid phenotype to explain the maintenance of hybridogenesis (exclusion of one parental genome in the germline before meiosis) was investigated in the Rana esculenta complex. Survival and growth of progenies from each parental and hybrid lineages were compared across contrasted conditions of oxygen availability (this factor is suspected to influence habitat utilization of each form of the complex). Whereas growth and development were strongly affected by constant hypoxic conditions in the R. ridibunda lineage, they were not altered in the R. lessonae lineage. Because the performance of the hybrid (R. esculenta) lineage proved to be intermediate between the parental species, no heterosis effect was detected. These results supported the intermediate niche hypothesis as an alternative to the heterotic hybrid superiority hypothesis. The ecological and evolutionary implications are then discussed.
Lung CSC‐derived exosomal miR‐210‐3p contributes to a pro‐metastatic phenotype in lung cancer by targeting FGFRL1

Lung cancer has the highest mortality rate among human cancers, and the majority of deaths can be attributed to metastatic spread. Lung cancer stem cells (CSCs) are a component of the tumour microenvironment that contributes to this process. Exosomes are small membrane vesicles secreted by all types of cells that mediate cell interactions, including cancer metastasis. Here, we show that lung CSC‐derived exosomes promote the migration and invasion of lung cancer cells, up‐regulate expression levels of N‐cadherin, vimentin, MMP‐9 and MMP‐1, and down‐regulate E‐cadherin expression. Moreover, we verified that these exosomes contribute to a pro‐metastatic phenotype in lung cancer cells via miR‐210‐3p transfer. The results of bioinformatics analysis and dual‐luciferase reporter assays further indicated that miR‐210‐3p may bind to fibroblast growth factor receptor‐like 1 (FGFRL1); silencing FGFRL1 enhanced the metastatic ability of lung cancer cells, whereas overexpressing FGFRL1 suppressed metastasis. Taken together, our results provide new insights into a potential molecular mechanism whereby lung CSC‐derived exosomal miR‐210‐3p targets FGFRL1 to promote lung cancer metastasis. FGFRL1 may be a promising therapeutic target in lung cancer.
Combined effect of repetitive transcranial magnetic stimulation and physical exercise on cortical plasticity

Physical exercise can minimize dysfunction and optimize functional motor recovery after stroke by modulating cortical plasticity. However, the limitation of physical exercise is that large amounts of time and effort are necessary to significantly improve motor function, and even then, substantial exercise may not be sufficient to normalize the observed improvements. Thus, interventions that could be used to strengthen physical exercise-induced neuroplasticity may be valuable in treating hemiplegia after stroke. Repetitive transcranial magnetic stimulation seems to be a viable strategy for enhancing such plasticity. As a non-invasive cortical stimulation technique, repetitive transcranial magnetic stimulation is able to induce long-term plastic changes in the motor system. Recently, repetitive transcranial magnetic stimulation was found to optimize the plastic changes caused by motor training, thereby enhancing the long-term effects of physical exercise in stroke patients. Therefore, it is believed that the combination of repetitive transcranial magnetic stimulation and physical exercise may represent a superior method for restoring motor function after stroke.
The prevalence of excessive sleepiness is higher in shift workers than in patients with obstructive sleep apnea

Excessive daytime sleepiness (EDS) is a common feature among shift workers as well as in obstructive sleep apnea (OSA) patients. There are several important accidents related to sleep disturbances causing EDS. The aim of this study was to evaluate EDS in a group of shift workers (regular rotating) from civil aviation and to compare them with OSA patients (n = 300) and with a group of regular workers (RW) (n = 140). Our sample was composed of 730 working‐age individuals (aged 18–67 years). The regular rotating shift workers (SW) sample was composed of 290 aeronautical mechanics. EDS was evaluated with the Epworth Sleepiness Scale (ESS) and defined as a score ≥ 11. The prevalence value obtained for the EDS of RW was 37.1%, for SW it was 60.7% and for OSA patients it was 40.7%. A logistic regression model for EDS in a subsample composed of men and matched for age and BMI, controlling for self‐reported sleep duration, showed an increased risk of EDS for SW (OR = 3.91, p = .001), with the RW group as reference. OSA patients did not differ from RW on EDS levels. This study emphasizes the presence of EDS in a shift work group of civil aviation professionals, which exceeded the EDS level of a positive control group of OSA patients. Sleep hygiene education for companies' workers and management is important and mitigation strategies should be implemented to reduce excessive sleepiness among workers.
