Effects of Acute Stretching on Cognitive Function and Mood States of Physically Inactive Young Adults

Exercise intensity from stretching is very low, making it well suited to varied populations, including physically inactive people. We tested the hypothesis that acute stretching would improve cognitive function and improved mood states in physically inactive people. We asked 19 physically inactive young participants to perform the Stroop task and complete the short form of Profile of Moods Scale before and after 10 minutes of whole body stretching using yoga techniques and poses (stretching condition) versus a resting period. In the stretching condition, we observed decreases in Tension–Anxiety, Depression–Dejection, Anger–Hostility, Fatigue, and Confusion scores on the Profile of Moods Scale (all p values < .01) and an increase in the Vigor score (p = .01). We also observed a decrease in Stroop interference performance (p < .001). Furthermore, we found a significant negative correlation between ΔVigor score and ΔStroop interference (r = −.36, p = .03), indicating that a greater increase in the Vigor score was associated with better cognitive performance. Thus, acute stretching improved mood states and cognitive performance in physically inactive people. We suggest that the improved cognitive performance may be, at least partly, associated with the improved mood states.
Kinesin Kif3b mutation reduces NMDAR subunit NR2A trafficking and causes schizophrenia‐like phenotypes in mice

The transport of N‐methyl‐d‐aspartate receptors (NMDARs) is crucial for neuronal plasticity and synapse formation. Here, we show that KIF3B, a member of the kinesin superfamily proteins (KIFs), supports the transport of vesicles simultaneously containing NMDAR subunit 2A (NR2A) and the adenomatous polyposis coli (APC) complex. Kif3b+/− neurons exhibited a reduction in dendritic levels of both NR2A and NR2B due to the impaired transport of NR2A and increased degradation of NR2B. In Kif3b+/− hippocampal slices, electrophysiological NMDAR response was found decreased and synaptic plasticity was disrupted, which corresponded to a common feature of schizophrenia (SCZ). The histological features of Kif3b+/− mouse brain also mimicked SCZ features, and Kif3b+/− mice exhibited behavioral defects in prepulse inhibition (PPI), social interest, and cognitive flexibility. Indeed, a mutation of KIF3B was specifically identified in human SCZ patients, which was revealed to be functionally defective in a rescue experiment. Therefore, we propose that KIF3B transports NR2A/APC complex and that its dysfunction is responsible for SCZ pathogenesis.
Analytical solution to swing equations in power grids

Objective To derive a closed-form analytical solution to the swing equation describing the power system dynamics, which is a nonlinear second order differential equation. Existing challenges No analytical solution to the swing equation has been identified, due to the complex nature of power systems. Two major approaches are pursued for stability assessments on systems: (1) computationally simple models based on physically unacceptable assumptions, and (2) digital simulations with high computational costs. Motivation The motion of the rotor angle that the swing equation describes is a vector function. Often, a simple form of the physical laws is revealed by coordinate transformation. Methods The study included the formulation of the swing equation in the Cartesian coordinate system, which is different from conventional approaches that describe the equation in the polar coordinate system. Based on the properties and operational conditions of electric power grids referred to in the literature, we identified the swing equation in the Cartesian coordinate system and derived an analytical solution within a validity region. Results The estimated results from the analytical solution derived in this study agree with the results using conventional methods, which indicates the derived analytical solution is correct. Conclusion An analytical solution to the swing equation is derived without unphysical assumptions, and the closed-form solution correctly estimates the dynamics after a fault occurs.
Self-efficacy, Hope as Mediators Between Positive Coping and Resilience Among Patients With Gastric Cancer Before the First Chemotherapy.

BACKGROUND Patients with gastric cancer experience severe psychological distress as a result of their cancer diagnosis and chemotherapy. Resilience is a defense mechanism that enables one to thrive amid distress. However, little research has been done to explore the formation and development mechanism of resilience among patients with gastric cancer before their first chemotherapy treatment. OBJECTIVE The mediating roles of self-efficacy and hope on the relationship between positive coping and resilience among patients with gastric cancer before their first chemotherapy treatment were examined to inform the future resilience intervention. METHODS A total of 253 patients with gastric cancer before their first chemotherapy treatment were investigated using the Simplified Coping Style Questionnaire, the General Self-efficacy Scale, the Herth Hope Index, and the 14-Item Resilience Scale. Structural equation modeling was conducted using Mplus version 7.03 to test the hypothesized mediational model. RESULTS Structural equation modeling analysis showed self-efficacy and hope completely mediated the relationship between positive coping and resilience; the indirect effects were 0.242 (P < .01) and 0.258 (P < .01), respectively; indirect effects accounted for 81% of the total effect. CONCLUSIONS Positive coping is not the independent predictor that may contribute to resilience among patients with gastric cancer before their first chemotherapy treatment, but it can indirectly affect resilience through self-efficacy and hope. IMPLICATIONS Self-efficacy and hope may increase the positive influence of positive coping on resilience among patients with gastric cancer before their first chemotherapy treatment. Resilience intervention might be enhanced by addressing the impact of positive coping on self-efficacy and hope.
A Systematic Review and Meta-Analysis of the Role of Sugar-Free Chewing Gum in Dental Caries

Objective: To determine the difference in level of dental caries in adults and children who chew sugar-free gum (SFG), compared with those who do not chew SFG or use alternatives such as lozenges, candies, rinses, tablets, and other nonchewing controls. Methods: Systematic review of published literature. Results: Twelve studies of interventions of SFG for dental caries outcomes were included. SFGs were found to significantly reduce caries increment, giving a preventative fraction (PF) of 28% (95% CI, 7% to 48%). Including the 8 trials that used xylitol gum only as the basis of the intervention, the PF was 33% (95% CI, 4% to 61%). No adverse effects were recorded. There was a high level of heterogeneity among the trials included. Conclusion: The findings of this review provide tentative evidence that chewing SFG reduces caries increment in comparison to nonchewing controls. However, there is a considerable degree of variability in the effect and the trials included were generally of moderate quality. There is a need for future research to explore the acceptability and feasibility of the use of SFG as a public health intervention (PROSPERO 2018 CRD42018094676). Knowledge Transfer Statement: The results of this study can be used by clinicians when deciding how best to implement dental caries prevention regimes for their patients. With consideration of cost and patient preference, this information could help to develop national policy directives on caries prevention and dictate the direction of future clinical research.
The Suitability of Orthogonal Hosts to Study Plant Cell Wall Biosynthesis

Plant cells are surrounded by an extracellular matrix that consists mainly of polysaccharides. Many molecular components involved in plant cell wall polymer synthesis have been identified, but it remains largely unknown how these molecular players function together to define the length and decoration pattern of a polysaccharide. Synthetic biology can be applied to answer questions beyond individual glycosyltransferases by reconstructing entire biosynthetic machineries required to produce a complete wall polysaccharide. Recently, this approach was successful in establishing the production of heteromannan from several plant species in an orthogonal host—a yeast—illuminating the role of an auxiliary protein in the biosynthetic process. In this review we evaluate to what extent a selection of organisms from three kingdoms of life (Bacteria, Fungi and Animalia) might be suitable for the synthesis of plant cell wall polysaccharides. By identifying their key attributes for glycoengineering as well as analyzing the glycosidic linkages of their native polymers, we present a valuable comparison of their key advantages and limitations for the production of different classes of plant polysaccharides.
Whole Blood Based Multiparameter Assessment of Thrombus Formation in Standard Microfluidic Devices to Proxy In Vivo Haemostasis and Thrombosis

Microfluidic assays are versatile tests which, using only small amounts of blood, enable high throughput analyses of platelet function in several minutes. In combination with fluorescence microscopy, these flow tests allow real-time visualisation of platelet activation with the possibility of examining combinatorial effects of wall shear rate, coagulation and modulation by endothelial cells. In particular, the ability to use blood and blood cells from healthy subjects or patients makes this technology promising, both for research and (pre)clinical diagnostic purposes. In the present review, we describe how microfluidic devices are used to assess the roles of platelets in thrombosis and haemostasis. We place emphasis on technical aspects and on experimental designs that make the concept of “blood-vessel-component-on-a-chip” an attractive, rapidly developing technology for the study of the complex biological processes of blood coagulability in the presence of flow.
A Multi-Omics Study of Chicken Infected by Nephropathogenic Infectious Bronchitis Virus

Chicken gout resulting from nephropathogenic infectious bronchitis virus (NIBV) has become a serious kidney disease problem in chicken worldwide with alterations of the metabolic phenotypes in multiple metabolic pathways. To investigate the mechanisms in chicken responding to NIBV infection, we examined the global transcriptomic and metabolomic profiles of the chicken’s kidney using RNA-seq and GC–TOF/MS, respectively. Furthermore, we analyzed the alterations in cecal microorganism composition in chickens using 16S rRNA-seq. Integrated analysis of these three phenotypic datasets further managed to create correlations between the altered kidney transcriptomes and metabolome, and between kidney metabolome and gut microbiome. We found that 2868 genes and 160 metabolites were deferentially expressed or accumulated in the kidney during NIBV infection processes. These genes and metabolites were linked to NIBV-infection related processes, including immune response, signal transduction, peroxisome, purine, and amino acid metabolism. In addition, the comprehensive correlations between the kidney metabolome and cecal microbial community showed contributions of gut microbiota in the progression of NIBV-infection. Taken together, our research comprehensively describes the host responses during NIBV infection and provides new clues for further dissection of specific gene functions, metabolite affections, and the role of gut microbiota during chicken gout.
Health-Related Quality of Life and Its Associated Factors in Prostate Cancer Patients Who Receive Androgen Deprivation Therapy.

BACKGROUND Presently, few studies have examined the impact of positive thinking on the HRQoL of prostate cancer patients who receive androgen deprivation therapy (ADT). OBJECTIVES We explored the factors that affect health-related quality of life (HRQoL), particularly positive thinking, of prostate cancer patients who receive ADT. METHODS A cross-sectional design was used. A total of 132 prostate cancer patients, drawn from outpatient clinics of 2 medical centers, who were receiving ADT were included. Structured questionnaires, including a basic information sheet, the Positive Thinking Scale, Social Support Scale, and Functional Assessment of Cancer Therapy-Prostate (FACT-P), were used for data collection. Statistical analysis was performed by using independent-sample t tests, one-way analysis of variance, Pearson correlation, and multiple regression. RESULTS Prostate cancer patients who were receiving ADT were more likely to engage in positive thinking, which was correlated with better social/family well-being, emotional well-being, functional well-being, prostate cancer concern, and a higher score on the FACT-P. Improved self-reported health status was correlated better with all subdimensions of HRQoL and better scores on the FACT-P. Greater social support was correlated with high social/family well-being. CONCLUSIONS Positive thinking, self-reported health status, and social support are important associated factors of HRQoL in prostate cancer patients who receive ADT. IMPLICATIONS FOR PRACTICE Oncology nurses can improve HRQoL by improving positive thinking, self-reported health status, and social support of prostate cancer patients who receive ADT.
Inferring the Genomic Landscape of Recombination Rate Variation in European Aspen (Populus tremula)

The rate of meiotic recombination is one of the central factors determining genome-wide levels of linkage disequilibrium which has important consequences for the efficiency of natural selection and for the dissection of quantitative traits. Here we present a new, high-resolution linkage map for Populus tremula that we use to anchor approximately two thirds of the P. tremula draft genome assembly on to the expected 19 chromosomes, providing us with the first chromosome-scale assembly for P. tremula (Table 2). We then use this resource to estimate variation in recombination rates across the P. tremula genome and compare these results to recombination rates based on linkage disequilibrium in a large number of unrelated individuals. We also assess how variation in recombination rates is associated with a number of genomic features, such as gene density, repeat density and methylation levels. We find that recombination rates obtained from the two methods largely agree, although the LD-based method identifies a number of genomic regions with very high recombination rates that the map-based method fails to detect. Linkage map and LD-based estimates of recombination rates are positively correlated and show similar correlations with other genomic features, showing that both methods can accurately infer recombination rate variation across the genome. Recombination rates are positively correlated with gene density and negatively correlated with repeat density and methylation levels, suggesting that recombination is largely directed toward gene regions in P. tremula.
Increased RLIP76 expression in IDH1 wild-type glioblastoma multiforme is associated with worse prognosis

Mutation of the isocitrate dehydrogenase (IDH) gene is regarded a novel indicator for the prognosis of patients with glioma. However, the role of the IDH1 gene mutations in carcinogenesis and the mechanisms underlying their function in glioblastoma multiforme (GBM) remain unknown. The present study aimed to determine whether the association of RLIP76 with the different IDH1 mutational status could serve as a putative biomarker for improving disease prognosis. Quantitative PCR, western blotting and immunohistochemical staining assays were used to investigate the expression levels of RLIP76 in 124 patients with GBM with different IDH1 mutational status. In addition, the association between RLIP76 expression, IDH1 mutational status and clinicopathological characteristics was investigated. The effects of RLIP76 expression and IDH1 mutational status on cell proliferation, cell apoptosis, and cell signaling were examined by Cell Counting Kit-8, flow cytometry and western blot assays, respectively. The data demonstrated that IDH1 wild-type (IDH1Wt) patients with low RLIP76 expression exhibited improved overall and progression-free survival. This effect was not observed in patients with IDH1 mutant (IDH1Mut) GBM. In vitro assays demonstrated that knockdown of IDH1 or overexpression of the IDH1 R132H mutation suppressed cell proliferation and promoted cell apoptosis in U87 glioma cells. Mechanistic studies further indicated that although the IDH1 R132H mutant phenotype exhibited similar antitumor effects on GBM cells as those observed with the IDH1 knockdown, it acted via a different mechanism with regard to the regulation of the apoptosis signaling pathway. IDH1 R132H mutant cells promoted p53-induced apoptosis, while the IDH1 knockdown inhibited the RLIP76-dependent apoptotic pathway in glioma cells. The findings of the present study provided insight to the contribution of IDH1 mutation in the development of GBM and indicated that RLIP76 may be considered as a prognostic biomarker of IDH1Wt GBM.
Cost-effectiveness of annual microalbuminuria screening in Thai diabetics

Background: Diabetes is a leading cause of end stage renal disease (ESRD), which impacts on treatment costs and patients' quality of life. Microalbuminuria screening in patients with diabetes as an early intervention is beneficial in slowing the progression of diabetic nephropathy. Objectives: We aimed to assess the cost-effectiveness of annual microalbuminuria screening in type 2 diabetic patients. Methods: We compared screening by urine dipsticks with a "do nothing" scenario. To replicate the natural history of diabetic nephropathy, a Markov model based on a simulated cohort of 10,000 45-year-old normotensive diabetic patients was utilized. We calculated the cost and quality of life gathered from a cross-sectional survey. The costs of dialysis were derived from The National Health Security Office (NHSO). We also calculated the incremental cost-effectiveness ratio (ICER) for lifetime with a future discount rate of 3%. Results: The ICER was 3,035 THB per quality-adjusted life year (QALY) gained. One-way and probabilistic sensitivity analyses showed that all ICERs were less than the Thai Gross Domestic Product (GDP) per capita(150,000 THB in 2011) based on World Health Organization's suggested criteria. Conclusions: Annual microalbuminuria screening using urine dipsticks in type 2 diabetic patients is very costeffective in Thailand based on World Health Organization's recommendations. This finding has corroboratedthe benefit of this screening in the public health benefit package. Keywords: Cost-effectiveness, diabetes, healthcare system, microalbuminuria, screening
Survival of bovine digital dermatitis treponemes on hoof knife blades and the effects of various disinfectants

Background Bovine digital dermatitis (BDD) is a painful infectious foot disease of cattle, and much evidence implicates a pathogenic role for treponemes. This study measured the survival of BDD treponemes on hoof knife blades and tested the efficacy of relevant disinfectants under laboratory conditions. Methods Two strains of BDD treponemes were applied to hoof knife blades under aerobic conditions. Swabs were taken at different time points (10 minutes, one hour, two hours, four hours and 18 hours) and again after 20-second disinfection time with one of five disinfectants. Swabs were used directly for nested PCR to detect treponemes or inoculated for anaerobic growth, and subsequently examined using phase contrast microscopy and PCR. Results BDD treponeme DNA was detectable by nested PCR at all survival time points, and these organisms were culturable from hoof knives for two hours after exposure under aerobic conditions in the laboratory. Three of the five disinfectants—1 per cent volume per volume (v/v) FAM30®, 2 per cent weight per volume (w/v) Virkon® or 2 per cent (v/v) sodium hypochlorite—were effective at preventing visible growth of treponemes following 20-seconds contact, and 1 per cent (v/v) FAM30® also prevented detection of treponemes by PCR. Conclusion Treponeme viability of two hours under aerobic conditions suggests BDD treponemes could be transmitted between cows on hoof knives. It is therefore important to apply a disinfection protocol during foot-trimming; the authors have identified three common disinfectants that may be suitable.
Supported solid lipid bilayers as a platform for single-molecule force measurements.

Biocompatible surfaces are important for basic and applied research in life science with experiments ranging from the organismal to the single-molecule level. For the latter, examples include the translocation of kinesin motor proteins along microtubule cytoskeletal filaments or the study of DNA--protein interactions. Such experiments often employ single-molecule fluorescence or force microscopy. In particular for force measurements, a key requirement is to prevent nonspecific interactions of biomolecules and force probes with the surface, while providing specific attachments that can sustain loads. Common approaches to reduce nonspecific interactions include supported lipid bilayers or PEGylated surfaces. However, fluid lipid bilayers do not support loads and PEGylation may require harsh chemical surface treatments and have limited reproducibility. Here, we developed and applied a supported solid lipid bilayer (SSLB) as a platform for specific, load bearing attachments with minimal nonspecific interactions. Apart from single-molecule fluorescence measurements, anchoring molecules to lipids in the solid phase enabled us to perform force measurements of molecular motors and overstretch DNA. Furthermore, using a heating laser, we could switch the SSLB to its fluid state allowing for manipulation of anchoring points. The assay had little nonspecific interactions, was robust, reproducible, time-efficient, and required less hazardous and toxic chemicals for preparation. In the long term, we expect that SSLBs can be widely employed for single-molecule fluorescence microscopy, force spectroscopy, and cellular assays in mechanobiology.
The Role of 18F-FDG PET/CT in Suspected Intraocular Sarcoidosis and Tuberculosis

ABSTRACT Purpose: To determine the utility of fluorine-18 fluorodeoxyglucose Positron Emission Tomography Computed Tomography (FDG PET/CT) in patients with suspected ocular sarcoidosis (OS) or intraocular tuberculosis (IOTB) in a resource-constrained, TB endemic area. Methods: Independent review of the FDG PET/CTs, Computed Tomography (CT) scans and chest radiographs (CXRs) of patients with suspected OS or IOTB and inconclusive conventional workup. Results: Twenty-nine PET/CTs and CXRs were reviewed, with 38% of PET/CTs and CTs demonstrating evidence of TB or sarcoidosis, compared to 21% of CXRs. The sensitivity, specificity, positive and negative predictive values for PET/CT and CT were similar - 85.7%, 95.5%, 85.7% and 95.5% for OS, and 33.3%, 100%, 100% and 68% for IOTB respectively and for CXR, 57.1%, 100%, 100% and 88% for OS, and 16.7%, 100%, 100% and 63% for IOTB. Conclusion: PET/CT added no significant additional benefit over Chest CT in patients with suspected OS or IOTB.
