Acoustic calibration in an echoic environment

Background: The sound fed to a loudspeaker may significantly differ from that reaching the ear of the listener. The transformation from one to the other consists of spectral distortions with strong dependence on the relative locations of the speaker and the listener as well as on the geometry of the environment. With the increased importance of research in awake, freely-moving animals in large arenas, it becomes important to understand how animal location influences the corresponding spectral distortions. New Method: We describe a full calibration pipeline that includes spatial sampling and estimation of the spectral distortions. We estimated the impulse responses of the environment using Golay complementary sequences. Using those sequences, we also describe an acoustic 3D localization method for freely moving animals. Results: In our arena, the impulse responses are dominated by a small number of strong reflections. We use this understanding to provide guidelines for designing the geometry of the environment as well as the presented sounds, in order to provide more uniform sound levels throughout the environment. Our 3D localization method achieves a 1 cm precision through the utilization of sound cues only. Comparison with Existing Methods: To our knowledge, this is the first description of a large-scale acoustic calibration pipeline with acoustic localization for neuroscience studies. Conclusions: Principled sampling of large arena allows for better design and control of the acoustic information provided to freely-moving animals.
A SimpleProbe® real‐time PCR assay for differentiating the canine parvovirus type 2 genotype

Canine parvovirus type 2 (CPV‐2) causes an important canine viral disease worldwide. CPV‐2 belongs to the Protoparvovirus genus in the family Parvoviridae. An amino acid change at position 426 of the VP2 protein differentiate types of CPV‐2, designated as CPV‐2a (Asn), CPV‐2b (Asp), and CPV‐2c (Glu). In this study, we compared CPV‐2 genotyping results obtained by SimpleProbe® real‐time PCR and DNA sequencing analysis to identify the accuracy and sensitivity of these methods.
Selective determination of nitrite/nitrate based on photo-induced redox activity of titanium dioxide.

Given its unique photocatalytic and structural properties, titanium dioxide was used as a sensitizer for the quantification of nitrite and nitrate contents by high-performance liquid chromatography with ultraviolet/nano-titanium dioxide photo-induced chemiluminescence detection. The photo-induced chemiluminescence signal was enhanced after the introduction of titanium dioxide. Ethylenediaminetetraacetic acid, as a positive hole scavenger, considerably improved the signal. The peak area of the chemiluminescence signal was enhanced 85 times after ethylenediaminetetraacetic acid was added to 1 × 10-6 mol/L of nitrite. The detection limits of nitrite and nitrate were 9.0 × 10-9 and 1.4 × 10-7 mol/L, respectively. Our method was applied for the determination of nitrite and nitrate contents in water samples. In contrast to other methods, our method is simple and environmentally friendly and enables the simultaneous determination of nitrite and nitrate.
The association between physical inactivity and obesity is modified by five domains of environmental quality in U.S. adults: A cross-sectional study

Physical inactivity is a primary contributor to the obesity epidemic, but may be promoted or hindered by environmental factors. To examine how cumulative environmental quality may modify the inactivity-obesity relationship, we conducted a cross-sectional study by linking county-level Behavioral Risk Factor Surveillance System data with the Environmental Quality Index (EQI), a composite measure of five environmental domains (air, water, land, built, sociodemographic) across all U.S. counties. We estimated the county-level association (N = 3,137 counties) between 2009 age-adjusted leisure-time physical inactivity (LTPIA) and 2010 age-adjusted obesity from BRFSS across EQI tertiles using multi-level linear regression, with a random intercept for state, adjusted for percent minority and rural-urban status. We modelled overall and sex-specific estimates, reporting prevalence differences (PD) and 95% confidence intervals (CI). In the overall population, the PD increased from best (PD = 0.341 (95% CI: 0.287, 0.396)) to worst (PD = 0.645 (95% CI: 0.599, 0.690)) EQI tertile. We observed similar trends in males from best (PD = 0.244 (95% CI: 0.194, 0.294)) to worst (PD = 0.601 (95% CI: 0.556, 0.647)) quality environments, and in females from best (PD = 0.446 (95% CI: 0.385, 0.507)) to worst (PD = 0.655 (95% CI: 0.607, 0.703)). We found that poor environmental quality exacerbates the LTPIA-obesity relationship. Efforts to improve obesity through LTPIA may benefit from considering this relationship.
Visual features for ego-centric activity recognition: a survey

Wearable cameras, which are becoming common mobile sensing platforms to capture the environment surrounding a person, can also be used to infer activities of the wearer. In this paper we critically discuss features for ego-centric activity recognition using videos. These features can be learned from data or designed to effectively encode motion magnitude, direction and other dynamics. Features can be derived from optical flow, from the displacement of key-points or the intensity centroid. We also discuss how features are effectively filtered and fused for specific tasks. Features presented in this paper can also be applied to other wearable systems that use accelerometer and gyroscope data.
Histological and molecular techniques utilized to investigate animal models of depression. An updated review

This review aimed to summarize the different histopathological techniques and procedures utilized during investigating the different animal models of depression in order to explore the pathophysiological aspect of depression and testing the efficacy of the antidepressant drugs or new treatments. This will be helpful while designing researches aiming to achieve these objectives. It was found that the major obstacle during investigating the animal models of depression was the restricted availability of validated animal models. The chronic stress models have face, construct, and predictive validity. It was found that the histological techniques used in investigating the animal models of depression that was described in the literatures fall under three categories; the light microscopic, the electron microscopic and the molecular biological studies. The light microscope studies were performed using the routine histological staining and immunohistochemical technique that aimed to describe the hippocampal histopathological changes induced by depression. Establishment of a preclinical behavioral science laboratory is highly recommended. It will encourage and support the conduction of high quality, multidisciplinary researches targeting anxiety and other psychiatric disorders and will indirectly improve the health care provided to the psychiatric patients.
University of Cost-effectiveness of internet-based training for primary care clinicians on antibiotic prescribing for acute respiratory-tract infections in Europe

31 Objectives: Overprescribing of antibiotics by general practitioners is seen as a major driver 32 of antibiotic resistance. Training in communication skills and C-reactive protein (CRP) 33 testing both appear effective in reducing such prescribing. This study assesses the cost- 34 effectiveness of (i) training general practitioners (GPs) in the use of CRP testing, (ii) training 35 GPs in communication skills and (iii) training GPs in both CRP testing and communication 36 skills compared to usual care. 37 Methods: Economic analyses (cost-utility analysis (CUA) accounting for the cost of 38 antibiotic resistance and cost-effectiveness analysis (CEA)) were both conducted from a 39 health care perspective with a time horizon of 28 days alongside a multinational, cluster, 40 randomised, factorial controlled trial in patients with respiratory tract infections in five 41 European countries. The primary outcome measures were QALYs and percentage reductions 42 in antibiotic prescribing. Hierarchical modelling was used to estimate an incremental cost- 43 per-QALY-gained and an incremental cost-per-percentage-reduction in antibiotic prescribing. 44 Results: Overall, the results of both the CUA and CEA showed that training in 45 communication skills is the most cost-effective. However, excluding the cost of antibiotic
Modeling Cutaneous Radiation Injury from Fallout

ABSTRACT Objective Beta radiation from nuclear weapons fallout could pose a risk of cutaneous radiation injury (CRI) to evacuating populations but has been investigated only cursorily. This work examines 2 components of CRI necessary for estimating the potential public health consequences of exposure to fallout: dose protraction and depth of dose. Methods Dose protraction for dry and moist desquamation was examined by adapting the biological effective dose (BED) calculation to a hazard function calculation similar to those recommended by the National Council on Radiation Protection and Measurements for other acute radiation injuries. Depth of burn was examined using Monte Carlo neutral Particle version 5 to model the penetration of beta radiation from fallout to different skin tissues. Results Nonlinear least squares analysis of the BED calculation estimated the hazard function parameter θ1 (dose rate effectiveness factors) as 25.5 and 74.5 (Gy-eq)2 h−1 for dry and moist desquamation, respectively. Depth of dose models revealed that beta radiation is primarily absorbed in the dead skin layers and basal layer and that dose to underlying tissues is small (<5% of dose to basal layer). Conclusions The low relative dose to tissues below the basal layer suggests that radiation-induced necrosis or deep skin burns are unlikely from direct skin contamination with fallout. These results enable future modeling studies to better examine CRI risk and facilitate effectively managing and treating populations with specialized injuries from a nuclear detonation.

Diet Quality Indices and Risk of Type 2 Diabetes Mellitus: The Singapore Chinese Health Study

We aimed to test whether predefined dietary patterns that are inversely related to risk of type 2 diabetes (T2D) in Western populations were similarly associated with lower T2D risk in an Asian population. We included 45,411 middle-aged and older participants (ages 45-74 years) in the Singapore Chinese Health Study who were free of diabetes, cancer, and cardiovascular disease at baseline (1993-1998). Participants were followed up for T2D diagnosis through 2010. Dietary information was collected using a validated food frequency questionnaire. Dietary pattern scores were calculated for the alternate Mediterranean diet (aMED), Alternate Healthy Eating Index 2010 (AHEI-2010), the Dietary Approaches to Stop Hypertension (DASH) diet, an overall plant-based diet index, and a healthful plant-based diet index. During a median of 11.1 years of follow-up, 5,207 incident cases of T2D occurred. After adjustment for multiple potential confounders, the 5 dietary pattern scores were significantly associated with 16% (for aMED) to 29% (for DASH) lower risks of T2D when comparing the highest score quintiles with the lowest (all P-for-trend values < 0.001). These associations did not vary substantially by baseline age, sex, body mass index, or hypertension status but were limited to nonsmokers (aMED: P for interaction < 0.001; AHEI-2010: P for interaction = 0.03). Adherence to a high-quality diet, as reflected by several predefined diet quality indices derived in Western populations, was significantly associated with lower T2D risk in an Asian population.
Effect of Visual Attention on Binocular Fusion Limits

We examined the effect of visual attention on binocular fusion limits by using Posner’s spatial cueing paradigm that entails cued shifts of attentional focus. Results showed that attention decreases the fusion limit. Observers perceived diplopia of a binocular line within +/−26.5 arcmin disparity (+/− correspond to uncrossed and crossed, respectively) more frequently when it was oriented to the line than when cued attention was directed elsewhere. We discuss the results in terms of attention increasing spatial resolution and contrast sensitivity.
Dihydromyricetin Attenuates Dexamethasone-Induced Muscle Atrophy by Improving Mitochondrial Function via the PGC-1α Pathway

Background/Aims: Skeletal muscle atrophy is an important health issue and can impose tremendous economic burdens on healthcare systems. Glucocorticoids (GCs) are well-known factors that result in muscle atrophy observed in numerous pathological conditions. Therefore, the development of effective and safe therapeutic strategies for GC-induced muscle atrophy has significant clinical implications. Some natural compounds have been shown to effectively prevent muscle atrophy under several wasting conditions. Dihydromyricetin (DM), the most abundant flavonoid in Ampelopsis grossedentata, has a broad range of health benefits, but its effects on muscle atrophy are unclear. The purpose of this study was to evaluate the effects and underlying mechanisms of DM on muscle atrophy induced by the synthetic GC dexamethasone (Dex). Methods: The effects of DM on Dex-induced muscle atrophy were assessed in Sprague-Dawley rats and L6 myotubes. Muscle mass and myofiber cross-sectional areas were analyzed in gastrocnemius muscles. Muscle function was evaluated by a grip strength test. Myosin heavy chain (MHC) content and myotube diameter were measured in myotubes. Mitochondrial morphology was observed by transmission electron microscopy and confocal laser scanning microscopy. Mitochondrial DNA (mtDNA) was quantified by real-time PCR. Mitochondrial respiratory chain complex activities were examined using the MitoProfile Rapid Microplate Assay Kit, and mitochondrial membrane potential was assessed by JC-1 staining. Protein levels of mitochondrial biogenesis and dynamics markers were detected by western blotting. Myotubes were transfected with siRNAs targeting peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α), mitochondrial transcription factor A (TFAM) and mitofusin-2 (mfn2) to determine the underlying mechanisms. Results: In vivo, DM preserved muscles from weight and average fiber cross-sectional area losses and improved grip strength. In vitro, DM prevented the decrease in MHC content and myotube diameter. Moreover, DM stimulated mitochondrial biogenesis and promoted mitochondrial fusion, rescued the reduced mtDNA content, improved mitochondrial morphology, prevented the collapse in mitochondrial membrane potential and enhanced mitochondrial respiratory chain complex activities; these changes restored mitochondrial function and improved protein metabolism, contributing to the prevention of Dex-induced muscle atrophy. Furthermore, the protective effects of DM on mitochondrial function and muscle atrophy were alleviated by PGC-1α siRNA, TFAM siRNA and mfn2 siRNA transfection in vitro. Conclusion: DM attenuated Dex-induced muscle atrophy by reversing mitochondrial dysfunction, which was partially mediated by the PGC-1α/TFAM and PGC-1α/mfn2 signaling pathways. Our findings may open new avenues for identifying natural compounds that improve mitochondrial function as promising candidates for the management of muscle atrophy.
Mouse Mast Cell Protease 4 Deletion Protects Heart Function and Survival After Permanent Myocardial Infarction

Chymase, a mast cell serine protease involved in the generation of multiple cardiovascular factors, such as angiotensin II and endothelin-1 (ET-1), is elevated and participates in tissue degeneration after permanent myocardial infarction (PMI). Anesthetized 4-month old male wild-type (WT) C57BL/6J mice and mouse mast cell protease-4 knockout (mMCP-4 KO) congeners were subjected to ligation of the left anterior descending (LAD) coronary artery. A group of mice was then subjected to Kaplan-Meier 28-day survival analysis. In another group of mice, 18F-fluorodeoxyglucose positron emission tomography (PET) was performed to evaluate heart function and the infarcted zone 3 days post-PMI surgery. Cardiac morphology following PMI was evaluated on formalin-fixed heart slices and glycoproteomic analysis was performed using mass spectrometry. Finally, cardiac and lung tissue content of immunoreactive ET-1 was determined. PMI caused 60% mortality in WT mice, due to left ventricular wall rupture, and 7% in mMCP-4 KO mice. Cardiac PET analysis revealed a significant reduction in left ventricular volume (systolic and diastolic) and preserved the ejection fraction in mMCP-4 KO compared to WT animals. The infarcted area, apoptotic signaling and wall remodeling were significantly decreased in mMCP-4 KO mice compared to their WT congeners, while collagen deposition was increased. Glycoproteomic analysis showed an increase in apolipoprotein A1, an established chymase substrate in mMCP-4 KO mice compared to WT mice post-PMI. ET-1 levels were increased in the lungs of WT, but not mMCP-4 KO mice, 24 h post-PMI. Thus, the genetic deletion of mMCP-4 improved survival and heart function post-PMI.
Social skills and the perception of interaction episodes

Accurate and well-differentiated cognitive representations about the social world are an important prerequisite of skilled social behaviour. The aim of this study was to demonstrate empirically that a significant relationship exists between social skill and the way an actor perceives and interprets various interaction episodes. Based on a free-response diary study, the most typical and common interaction episodes in a subcultural milieu were established. A second sample from the same milieu were asked (a) to indicate their perception of these episodes, and (b) to complete a battery of social skill assessment scales as well as personality scales. The episode judgements data were analysed using an Individual Differences Multidimensional Scaling (INDSCAL) procedure, identifying three episode dimensions (social anxiety, evaluation and perceived intensity). Subjects falling within the top and the bottom quartiles of the distribution on the social skills measures had significantly different cognitive representations about these episodes, with low skilled actors relying on the social anxiety dimension, and high skilled actors on the evaluation and intensity dimensions most heavily. The nature of these differences was further explicated by a canonical correlation analysis, showing that sex and personality variables were also related to episode cognition. The results are interpreted as indicating the important role episode representations play in social skills, and the implications of the findings for social skills assessment and therapy are discussed.
Bapx1 is required for jaw joint development in amphibians

The acquisition of a movable jaw and a jaw joint are key events in gnathostome evolution. Jaws are derived from the neural crest derived pharyngeal skeleton and the transition from jawless to jawed vertebrates consists of major morphological changes, which must have a genetic foundation. Recent studies on the effects of bapx1 knockdown in fish and chicken indicate that bapx1 has acquired such a role in primary jaw joint development during vertebrate evolution, but evidence from amphibians is missing so far. In the present study, we use Ambystoma mexicanum, Bombina orientalis, and Xenopus laevis to investigate the effects of bapx1 knockdown on the development of these three different amphibians. Using morpholinos we downregulated the expression of bapx1 and obtain morphants with altered mandibular arch morphology. In the absence of bapx1 Meckeĺs cartilage and the palatoquadrate jaw joint initially develop separately but during further development the joint cavity between both fills with chondrocytes. This results in the fusion of both cartilages and the loss of the jaw joint. Despite this the jaw itself remains usable for feeding and breathing. We show that bapx1 plays a role in jaw joint maintenance during development and that the morphants morphology possibly mirrors the morphology of the jawless ancestors of the gnathostomes.
What are the factors that contribute to the development of sexual dysfunction in breastfeeding women? A systematic scoping review protocol

Introduction Female sexual dysfunction is a public health problem. Evidence suggests that the population of nursing women is more vulnerable to the phenomenon due to breast feeding. Thus, this protocol was developed to explore the factors that contribute to the development of sexual dysfunction in breastfeeding women. Methods and analysis The systematic scoping review will be conducted in six stages, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols. The databases used will be: PubMed, Excerpta Medica Database, Cumulative Index for Nursing and Allied Health Literature, PsycINFO, Science Direct, Web of Science and Google Scholar. The searches were made until 1 June 2018, and no retrospective time limit was used. For the organisation of the literature retrieved from the databases, the EndNote Basic manager will be used. The Cochrane model will be used for the data extraction. The analysis of the quantitative data will be carried out through descriptive statistics and the qualitative data will be submitted to thematic analysis. The methodological quality of the empirical studies will be evaluated using the Mixed Methods Appraisal Tool. Ethics and dissemination As it will be a review study, without human involvement, there will be no need for ethical approval. The results will be disseminated in a scientific journal, as well as in various media, such as: conferences, seminars, congresses or symposia.
Differences in the Repeated Sprint Performance Between the First and Latter Halves of Trials Under Conditions of Several Thermal States in Exercising Muscles.

Inoue, K, Yamashita, N, Kume, M, and Yoshida, T. Differences in the repeated sprint performance between the first and latter halves of trials under conditions of several thermal states in exercising muscles. J Strength Cond Res XX(X): 000-000, 2018-The purpose of this study was to determine whether the effects of thermal states in exercising muscle on repeated sprint cycling (RSC) performance differ between the first and latter half of trials. Nine male subjects performed 8 × 8 seconds of RSC with a 40-second rest period. The subjects wore water-perfused trousers with water at 6° C (COLD), 17° C (COOL), 30° C (WARM), or 44° C (HOT). During the first half of trials, the peak power output (PPO), mean power output (MPO), and sum of work output (SWO) were significantly (p < 0.05) greater under the WARM and HOT conditions than under the COLD and COOL conditions, and a difference in the PPO and MPO between WARM and HOT was noted in the second sprint bout during the first half of the exercise. However, during the latter half of trials, there was no significant difference in the PPO, MPO, and SWO among the 4 conditions. The tympanic temperature (Tty) was significantly elevated under the HOT condition but fell under the COLD and COOL conditions, whereas the Tty under the WARM condition did not change significantly (p < 0.05) during the experiment. The total sweat loss was significantly (p < 0.05) greater in the HOT condition than in the other conditions. These results suggest that the effect of thermal states in exercising muscle on the RSC performance is greater in the first half of exercise than in the latter half, possibly because of the elevation of the core temperature and sweat loss under HOT conditions.
