Dietary-Induced Low-Grade Inflammation in the Liver

The literature describes a close correlation between metabolic disorders and abnormal immune responses, like low-grade inflammation (LGI), which may be one mechanistic link between obesity and various comorbidities, including non-alcoholic fatty liver disease (NAFLD). In our study, we investigated the influence of dietary composition on obesity-derived LGI in the liver. We used a dietary induced obesity mouse model of C57BL/6J mice fed with high fat diet (HFD, 60% fat, 20% protein, 20% carbohydrates) and two different controls. One was rich in carbohydrates (10% fat, 20% protein, 70% carbohydrates), further referred to as the control diet (CD), and the other one is referred to as the standard diet (SD), with a more balanced macronutrient content (9% fat, 33% protein, 58% carbohydrates). Our results showed a significant increased NAFLD activity score in HFD compared to both controls, but livers of the CD group also differed in their macroscopic appearance from healthy livers. Hepatic fat content showed significantly elevated cholesterol concentrations in the CD group. Histologic analysis of the cellular immune response in the liver showed no difference between HFD and CD and expression analysis of immunologic mediators like interleukin (IL)-1β, IL-6, IL-10 and tumor necrosis factor alpha also point towards a pro-inflammatory response to CD, comparable to LGI in HFD. Therefore, when studying diet-induced obesity with a focus on inflammatory processes, we encourage researchers to carefully select controls and not use a control diet disproportionally rich in carbohydrates.
Why Is an Early Start of Training Related to Musical Skills in Adulthood? A Genetically Informative Study

Experts in domains such as music or sports often start training early. It has been suggested that this may reflect a sensitive period in childhood for skill acquisition. However, it could be that familial factors (e.g., genetics) contribute to the association. Here, we examined the effect of age of onset of musical training on musical aptitude and achievement in professional musicians (n = 310) and twins (n = 7,786). In line with previous literature, results showed that an earlier age of onset was associated with higher aptitude and achievement in both samples. After we adjusted for lifetime practice hours, age of onset was associated only with aptitude (p < .001; achievement: p > .14). Twin analyses showed that the association with aptitude was fully explained by familial factors. Thus, these findings provide little support for a sensitive period for music but highlight that familiar factors play an important role for associations between age of onset of training and skills in adulthood.
Phanuromyia ricaniae Nam, Lee Talamas sp. n. (Hymenoptera: Scelionidae) reared from the eggs of Ricania shantungensis Chou Lu (Hemiptera: Ricaniidae) in Asia.

The genus Phanuromyia in the subfamily Telenominae (Hymenoptera: Scelionidae) consists of 60 described species, for which host records indicate they are egg parasitoids of lanternflies and planthoppers (Hemiptera: Auchenorrhyncha). In this study, we describe a new species of the genus, P. ricaniae sp. n. , reared from the eggs of a planthopper, Ricania shantungensis Chou Lu (Hemiptera: Ricaniidae). This planthopper has been considered as a serious invasive pest in South Korean agriculture. Ricania shantungensis has a wide host range, including economically important crops such as apple, peach, and pear. Phanuromyia ricaniae therefore has the potential to be a biological control agent against ricaniid planthoppers.
Hydrocarbon-Degrading Bacteria Found Tightly Associated with the 50–70 μm Cell-Size Population of Eukaryotic Phytoplankton in Surface Waters of a Northeast Atlantic Region

The surface of marine eukaryotic phytoplankton can harbour communities of hydrocarbon-degrading bacteria; however, this algal–bacterial association has, hitherto, been only examined with non-axenic laboratory cultures of micro-algae. In this study, we isolated an operationally-defined community of phytoplankton, of cell size 50–70 μm, from a natural community in sea surface waters of a subarctic region in the northeast Atlantic. Using MiSeq 16S rRNA sequencing, we identified several recognized (Alcanivorax, Marinobacter, Oleispira, Porticoccus, Thalassospira) and putative hydrocarbon degraders (Colwelliaceae, Vibrionaceae) tightly associated with the phytoplankton population. We combined fluorescence in situ hybridisation with flow-cytometry (FISH-Flow) to examine the association of Marinobacter with this natural eukaryotic phytoplankton population. About 1.5% of the phytoplankton population contained tightly associated Marinobacter. The remaining Marinobacter population were loosely associated with either eukaryotic phytoplankton cells or non-chlorophyll particulate material. This work is the first to show the presence of obligate, generalist and putative hydrocarbonoclastic bacteria associated with natural populations of eukaryotic phytoplankton directly from sea surface water samples. It also highlights the suitability of FISH-Flow for future studies to examine the spatial and temporal structure and dynamics of these and other algal–bacterial associations in natural seawater samples.
Developing Advanced Catalysts for the Conversion of Polyolefinic Waste Plastics into Fuels and Chemicals

The present review is aimed at exploring the field of the catalytic cracking of polyolefins over solid acids, focusing on the role played by the catalysts toward the synthesis of fuels and chemicals as well as on the reaction systems currently used. Initially, conventional solid acids, such as micrometer sized crystal zeolites and silica–alumina, were used to establish the relationship among their activity, selectivity, and deactivation in the polyolefin cracking and the inherent properties of the catalysts (acidity, pore structure); however, the occurrence of steric and diffusional hindrances for entering the zeolite micropores posed by the bulky nature of the polyolefins highlighted the importance of having easily accessible acid sites, either through mesopores or by a high external surface area. This fact led toward the investigation of mesoporous materials (Al-MCM-41, Al-SBA-15) and nanozeolites, which allowed increasing the catalytic activities, especially for the case of polypropylene. Further advan.
Biological versus mechanical aortic valve replacement in non-elderly patients: a single-centre analysis of clinical outcomes and quality of life.

OBJECTIVES The aim of this study was to evaluate short- and long-term clinical outcomes, including the perceived health-related quality of life, in patients younger than 65 years having undergone aortic valve replacement either with biological or mechanical valve prostheses. METHODS Between 2002 and 2013, 242 consecutive patients <65 years of age underwent isolated aortic valve replacement at our institution, either with biological (n = 134, 55.4%) or mechanical (n = 108, 44.6%) prostheses. Survival, health-related quality of life, short- and long-term clinical outcomes and echocardiographic data were analysed with a retrospective, single-centre study. Propensity matching was performed. RESULTS No significant difference in survival was found between the 2 groups (mechanical versus biological: 100% vs 96.6% at 1 year, 98.2% vs 93.1% at 5 years and 92.3% vs 83.4% at 10 years after surgery, P = 0.091). For all the interviewed patients (n = 161, 66.5%), perceived quality of life at the latest follow-up was excellent. Need for reoperation was higher in the bioprosthetic group (8% vs 0%, P = 0.995), whereas the rate of major bleedings was higher in the mechanical valve group (3% vs 20%, P = 0.094). The mean and maximum transvalvular pressure gradients were 20.5 ± 9.7 and 37.4 ± 17.5 mmHg in the biological group and 14.8 ± 4.8 and 26.6 ± 9.2 mmHg in the mechanical group (P = 0.014). CONCLUSIONS No significant differences were found between biological and mechanical valves in terms of patients' survival, clinical outcomes and quality of life. Mean and maximum transvalvular pressure gradients were significantly higher in the biological group. The majority of patients would opt for the same prosthesis type, if asked to choose again.
Multimodal Assessment of the Motor System in Patients With Chronic Ischemic Stroke

Supplemental Digital Content is available in the text. Background and Purpose: Despite continuing efforts in the multimodal assessment of the motor system after stroke, conclusive findings on the complementarity of functional and structural metrics of the ipsilesional corticospinal tract integrity and the role of the contralesional hemisphere are still lacking. This research aimed to find the best combination of motor system metrics, allowing the classification of patients into 3 predefined groups of upper limb motor recovery. Methods: We enrolled 35 chronic ischemic stroke patients (mean 47 [26–66] years old, 29 [6–58] months poststroke) with a single supratentorial lesion and unilateral upper extremity weakness. Patients were divided into 3 groups, depending on upper limb motor recovery: good, moderate, and bad. Nonparametric statistical tests and regression analysis were used to investigate the relationships among microstructural (fractional anisotropy (FA) ratio of the corticospinal tracts at the internal capsule (IC) level (classic method) and along the length of the tracts (Fréchet distance), and of the corpus callosum) and functional (motor evoked potentials [MEPs] for 2 hand muscles) motor system metrics. Stratification rules were also tested using a decision tree classifier. Results: IC FA ratio in the IC and MEP absence were both equally discriminative of the bad motor outcome (96% accuracy). For the 3 recovery groups’ classification, the best parameter combination was IC FA ratio and the Fréchet distance between the contralesional and ipsilesional corticospinal tract FA profiles (91% accuracy). No other metrics had any additional value for patients’ classification. MEP presence differed for 2 investigated muscles. Conclusions: This study demonstrates that better separation between 3 motor recovery groups may be achieved when considering the similarity between corticospinal tract FA profiles along its length in addition to region of interest-based assessment and lesion load calculation. Additionally, IC FA ratio and MEP absence are equally important markers for poor recovery, while for MEP probing it may be important to investigate more than one hand muscle.
Prevalence of respiratory viruses using polymerase chain reaction in children with wheezing, a systematic review and meta–analysis

Introduction Wheezing is a major problem in children, and respiratory viruses are often believed to be the causative agent. While molecular detection tools enable identification of respiratory viruses in wheezing children, it remains unclear if and how these viruses are associated with wheezing. The objective of this systematic review is to clarify the prevalence of different respiratory viruses in children with wheezing. Methods We performed an electronic in Pubmed and Global Index Medicus on 01 July 2019 and manual search. We performed search of studies that have detected common respiratory viruses in children ≤18 years with wheezing. We included only studies using polymerase chain reaction (PCR) assays. Study data were extracted and the quality of articles assessed. We conducted sensitivity, subgroup, publication bias, and heterogeneity analyses using a random effects model. Results The systematic review included 33 studies. Rhinovirus, with a prevalence of 35.6% (95% CI 24.6–47.3, I2 98.4%), and respiratory syncytial virus, at 31.0% (95% CI 19.9–43.3, I2 96.4%), were the most common viruses detected. The prevalence of other respiratory viruses was as follows: human bocavirus 8.1% (95% CI 5.3–11.3, I2 84.6%), human adenovirus 7.7% (95% CI 2.6–15.0, I2 91.0%), influenza virus6.5% (95% CI 2.2–12.6, I2 92.4%), human metapneumovirus5.8% (95% CI 3.4–8.8, I2 89.0%), enterovirus 4.3% (95% CI 0.1–12.9, I2 96.2%), human parainfluenza virus 3.8% (95% CI 1.5–6.9, I2 79.1%), and human coronavirus 2.2% (95% CI 0.6–4.4, I2 79.4%). Conclusions Our results suggest that rhinovirus and respiratory syncytial virus may contribute to the etiology of wheezing in children. While the clinical implications of molecular detection of respiratory viruses remains an interesting question, this study helps to illuminate the potential of role respiratory viruses in pediatric wheezing.

Race-based disparities in presentation and outcomes in infrainguinal bypass patients.

BACKGROUND Racial disparities in healthcare are well documented, however their effects on surgical outcomes remain controversial. While studies have examined outcomes along the whiteblack dichotomy, Asian populations remain frequently unstudied. We use the VQI to examine disparities among white, black, and Asian patients undergoing infrainguinal bypass. METHODS The VQI database was queried for black, white, and Asian patients undergoing infrainguinal surgery between 2012 and 2017. Preoperative characteristics, disease severity, and perioperative characteristics were compared between the racial groups. Primary outcomes included overall mortality, time to death, long term loss of primary patency, and patency at discharge. Analyses were done using a 1:3:3 matched sample of Asian to whites to black patients. RESULTS 139 (0.56%) Asian, 4,222 (16.9%) black, and 20,582 (82.5%) white patients were included, of which 129 Asian patients were matched to 387 black and 387 white patients. Asian patients had more advanced disease as demonstrated by higher rates of tissue loss/acute ischemia (p <0.0001) and the highest percentage of below knee popliteal target sites (p = 0.0011). There were no differences in mortality (p = 0.6808) or long-term loss of primary patency (p = 0.4500). However, black patients had higher rates of amputation (OR = 1.68, p = 0.0224) and reoperation (OR = 2.22, p = 0.0015). CONCLUSIONS Asian patients presented with more advanced disease requiring more distal bypass targets. Despite these disparities in presentation, overall long-term primary patency and mortality showed no significant difference.
Single Cell Detection of the p53 Protein by Mass Cytometry

Simple Summary Investigation of protein expression in cancer cells is an important part of the diagnostic process. Increasing knowledge about expression of different proteins has been exploited for prognostic assessments and in some cases also for selection of treatment. The p53 protein has proven important in development of various cancers, and the expression of this protein and its signaling pathway is therefore of interest when examining cancer patient samples. Here, we present mass cytometry as a tool for detection of p53 expression. Mass cytometry allows for measurement of up to 50 parameters per sample with single cell resolution, and we aim to demonstrate its potential for p53-focused research. Abstract Purpose: The p53 protein and its post-translational modifications are distinctly expressed in various normal cell types and malignant cells and are usually detected by immunohistochemistry and flow cytometry in contemporary diagnostics. Here, we describe an approach for simultaneous multiparameter detection of p53, its post-translational modifications and p53 pathway-related signaling proteins in single cells using mass cytometry. Method: We conjugated p53-specific antibodies to metal tags for detection by mass cytometry, allowing the detection of proteins and their post-translational modifications in single cells. We provide an overview of the antibody validation process using relevant biological controls, including cell lines treated in vitro with a stimulus (irradiation) known to induce changes in the expression level of p53. Finally, we present the potential of the method through investigation of primary samples from leukemia patients with distinct TP53 mutational status. Results: The p53 protein can be detected in cell lines and in primary samples by mass cytometry. By combining antibodies for p53-related signaling proteins with a surface marker panel, we show that mass cytometry can be used to decipher the single cell p53 signaling pathway in heterogeneous patient samples. Conclusion: Single cell profiling by mass cytometry allows the investigation of the p53 functionality through examination of relevant downstream signaling proteins in normal and malignant cells. Our work illustrates a novel approach for single cell profiling of p53.
The role of H2 reduction in the growth of single-walled carbon nanotubes

Carbon nanotubes (CNTs) with their high mechanical, electrical, thermal and chemical properties are regarded as promising materials for many different potential applications. Chemical vapor deposition (CVD) is a common method for CNT synthesis especially for mass production. There are important parameters (synthesis temperature, catalyst and calcination conditions, substrate, carbon source, synthesis time, H2 reduction, etc.) affecting the structure, morphology and the amount of the CNT synthesis. In this study, CNTs were synthesized by CVD of acetylene (C2H2) on magnesium oxide (MgO) powder substrate impregnated by iron nitrate (Fe (NO3)3•9H2O) solution. The synthesis conditions were as follows: at catalyst calcination temperatures of 400 and 550°C, calcination time of 0, 15, 30 and 45 min, hydrogen concentrations of 0, 50 and 100 % vol, synthesis temperature of 800°C and synthesis time of 30 minutes. The synthesized materials were characterized by thermal gravimetric analysis (TGA), transmission electron microscopy (TEM), X ray diffraction (XRD) and Raman spectroscopy. Effects of H2 reduction on catalyst calcination and CNT synthesis were investigated.
Neural Correlates of Audiovisual Temporal Binding Window in Individuals With Schizotypal and Autistic Traits: Evidence From Resting‐State Functional Connectivity

Temporal proximity is an important clue for multisensory integration. Previous evidence indicates that individuals with autism and schizophrenia are more likely to integrate multisensory inputs over a longer temporal binding window (TBW). However, whether such deficits in audiovisual temporal integration extend to subclinical populations with high schizotypal and autistic traits are unclear. Using audiovisual simultaneity judgment (SJ) tasks for nonspeech and speech stimuli, our results suggested that the width of the audiovisual TBW was not significantly correlated with self‐reported schizotypal and autistic traits in a group of young adults. Functional magnetic resonance imaging (fMRI) resting‐state activity was also acquired to explore the neural correlates underlying inter‐individual variability of TBW width. Across the entire sample, stronger resting‐state functional connectivity (rsFC) between the left superior temporal cortex and the left precuneus, and weaker rsFC between the left cerebellum and the right dorsal lateral prefrontal cortex were correlated with a narrower TBW for speech stimuli. Meanwhile, stronger rsFC between the left anterior superior temporal gyrus and the right inferior temporal gyrus was correlated with a wider audiovisual TBW for non‐speech stimuli. The TBW‐related rsFC was not affected by levels of subclinical traits. In conclusion, this study indicates that audiovisual temporal processing may not be affected by autistic and schizotypal traits and rsFC between brain regions responding to multisensory information and timing may account for the inter‐individual difference in TBW width.
Temporal profile of serum neurofilament light in multiple sclerosis: Implications for patient monitoring

Objective: To understand how longitudinal serum neurofilament light chain (sNfL) patterns can inform its use as a prognostic biomarker in multiple sclerosis (MS) and evaluate whether sNfL reflects MS disease activity and disease-modifying therapy usage. Methods: This was a post hoc analysis of longitudinal data and samples from the ADVANCE trial (NCT00906399) of patients with relapsing–remitting MS (RRMS). sNfL was measured every 3 months for 2 years, then every 6 months for 4 years. Regression models explored how sNfL data predicted 4-year values of brain volume, expanded disability status scale score, and T2 lesions. sNfL levels were assessed in those receiving placebo, peginterferon beta-1a, and those with disease activity. Results: Baseline sNfL was a predictor of 4-year brain atrophy and development of new T2 lesions. Clinical (p = 0.02) and magnetic resonance imaging (MRI) (p < 0.01) outcomes improved in those receiving peginterferon beta-1a whose sNfL decreased to <16 pg/mL after 12 months versus those whose sNfL remained ⩾16 pg/mL. Mean sNfL levels decreased in peginterferon beta-1a-treated patients and increased in placebo-treated patients (–9.5% vs. 6.8%; p < 0.01). sNfL was higher and more variable in patients with evidence of active MS. Conclusion: These data support sNfL as a prognostic and disease-monitoring biomarker for RRMS.
The Relationship Between Polysubstance Injection Drug Use, HIV Risk Behaviors, and Interest in Pre-Exposure Prophylaxis (PrEP) Among People Who Inject Drugs in Rural West Virginia.

OBJECTIVE The opioid crisis has increased risks for injection drug use (IDU)-associated HIV outbreaks throughout the United States. Polysubstance use and syringe sharing are common among rural people who inject drugs (PWID). However, little is known about how polysubstance IDU affects engagement in HIV prevention efforts among non-urban PWID. This study assesses the associations between profiles of polysubstance injection, injection-related HIV risk, acquiring syringes from a syringe services program (SSP), HIV testing, and pre-exposure prophylaxis (PrEP) awareness and interest among PWID in rural Appalachia. METHOD We used survey data from 392 respondents in Cabell County, West Virginia who had injected drugs in the past 6 months. We conducted a latent class analysis using seven measures of IDU and tested for associations with injection-related HIV risk, receiving syringes from an SSP, having been tested for HIV, and PrEP awareness and interest. RESULTS We identified three classes of polysubstance IDU in our sample: polysubstance use, heroin and crystal methamphetamine use, and crystal methamphetamine and buprenorphine/suboxone use. The polysubstance use class had the highest injection-related HIV risk (81.8% at risk), high syringe acquisition at an SSP (67.7%), and highest rate of HIV testing (60.0%). PrEP awareness was low across the sample (30.0%), but most PWID expressed interest in using PrEP (57.7%). CONCLUSIONS Patterns of polysubstance IDU have unique relationships with key HIV risk factors and protective behaviors. The expansion of harm reduction services in rural settings is warranted to prevent incident HIV infections.
Isotherms of Fluids in Native and Defective Zeolite and Alumino-Phosphate Crystals: Monte-Carlo Simulations with “On-the-Fly” ab initio Electrostatic Potential

We use periodic Density Functional Theory (DFT) method to generate the electrostatic potentials of adsorption materials and use them in Grand Canonical Monte Carlo simulations of fluid adsorption isotherms. This permits us to consider complex solids showing defects and without a priori knowledge of their electrostatic parameters for the Monte Carlo simulations. We apply the method to aluminophosphate and silicate solids of ZON type and evaluate their affinity to adsorb and separate CO2 -N2 (H2 O) mixtures.
