Cardiac Autonomic Responses and Adaptation to Repeated Bouts of Eccentric Exercise

It is a well-known fact that participating in systemically designed exercise training provides critical benefits that prevent premature mortality due to cardiovascular diseases [1]. Resistance training may also enhance heart rate variability (HRV), reflecting cardiac autonomic regulation (CAR) in patients with cardiac autonomic imbalance [2]. However, controversies remain regarding the cardio-protective effects of regular physical activity, in particular resistance training. For instance, a previous study investigating the effects of 12-week isokinetic eccentric strength training in healthy older men indicated a significant increase in the peak torques of the quadriceps and hamstring muscle groups [3]. However, contrary to their hypothesis, the authors were faced with an unexpected result. Eccentric resistance training led to a decrease in HRV, and further, a physiological mechanism that explains eccentric training-induced cardiac autonomic imbalance has not been identified to date [3]. The effects of exercise training may be attributed to physiological responses to a single session of exercise and post-exercise hypotension was found to contribute to the improvement of the hypertension induced by exercise training in a previous study [4]. The eccentric resistance exercise PURPOSE: The current study was performed to examine the effects of acute eccentric resistance exercise (ERE) on heart rate variability (HRV) and to determine whether cardiac autonomic regulation adapts to the repeated bout effect. METHODS: Isokinetic eccentric exercise consisted of five sets of six maximal contractions of the knee extensor with an angular velocity of 90°/second. College-aged men (n=11) underwent two sessions of ERE with a 3-week interval. Muscle damage indicators such as the range of motion (ROM) and muscle echo intensity (EI) were measured. The post-exercise cardiac autonomic response was assessed by spectral analysis of HRV. Low frequency (LF) and high frequency (HF) bands, the normalized unit (nu) for each band power, and the LF-to-HF (LF/HF) ratio were determined. All variables were recorded at 24, 48, 72, and 96 hours post-exercise as well as before and immediately after ERE. RESULTS: The EI and ROM of the rectus femoris changed significantly after the maximal ERE. There was a significant interaction effect between the time and bout for EI. Significant changes in LF and HF nu were observed at 72 (1st ERE) and 96 hours (2nd ERE) after each ERE. The LF/HF ratio was also significantly increased at 24 (1st ERE) and 72 hours (2nd ERE) after each ERE. However, no interaction effects on changes in the HRV indices were observed. CONCLUSIONS: The present study suggests that acute ERE leads to cardiac autonomic imbalance for a sustained period and that repeated bouts of ERE cannot alleviate cardiac autonomic responses to exercise.
Experimental Investigation of the Production of Sustainable Lightweight Concrete

An experimental study on four types of coarse aggregate was conducted to produce lightweight concrete. These four types are namely; white limestone, red limestone, clay brick fragments, and pumice. Ordinary Portland cement was used for all examined mixes. Water to cement ratio (w/c) was modified according to the effect of coarse aggregate type on the workability of the resulted concrete for each mix. The reference concrete mix, which is normal concrete, water to cement ratio used was (0.5). The investigated characteristics for all concrete mixes were workability, compressive strength, dry density, absorption, and thermal conductivity. Results indicated that the aggregate type significantly affects most of the properties of lightweight concrete mixes such as workability, density, and thermal insulation for all tested types of concrete. All investigated specimens indicated improvement in terms of density, workability, and thermal conductivity when compared to the reference concrete mix. Yet, it was derived from the testing results that using pumice in lightweight concrete production is the optimum option among the other examined types. When compared to normal concrete, this type of lightweight concrete showed a 41% decrease in dry density, nearly 72.54% decrease in thermal conductivity, and about 12% increase in workability. However, it is vital to notice that due to the low compressive strength and the relatively high absorption capability for all the examined types of lightweight concrete, it is suggested to use these types of concrete for non-structural walls that are not subjected to or exposed to high humidity.

Changes of meat quality characteristics and intramuscular connective tissue of beef semitendinosus muscle during postmortem aging for Chinese Yellow bulls

Summary This study was designed to explore the changes of meat quality characteristics and intramuscular connective tissue of beef semitendinosus muscle during postmortem aging for Chinese Yellow bulls. Semitendinosus muscles were obtained at day 4 postmortem and then further aged for different periods. Chemical determinations, histological and mechanical measurements were performed for the raw and cooked steaks on days 4, 11, 14, 21, and 28 postmortem, respectively. The results showed that postmortem aging resulted in an increase in moisture content and collagen solubility, a decrease in filtering residues, primary perimysial thickness, fibre diameter, Warner-Bratzler shear force, and transition temperature of the endomysium. The synergic effects of the myofibril and the intramuscular connective tissue determined the tenderness of aged beef.
Feature Gate Computational Top-Down Model for Target Detection

Computer vision is a technique used for processing images and videos which are increasingly becoming ubiquitous day by day. Technologies developed are revolving around human needs and demands high computational power as volume of data increases. The extraction of the necessary information for processing, that is independent of various scene complexity is a challenging task. Computation visual attention methods channelize a way to select the information using psychological studies on the human visual system. This work aims to develop a computational visual attention method to select the target in a scene. Feature Gate Top-Down model is proposed to ﬁlter the signiﬁcant region of a target in the scene. The proposed model is extended as a choice-based system to detect target or salient movement in surveillance videos. Experimental analysis is performed on various scenes for detecting human as a target followed by the analysis on surveillance videos is evaluated. The metrics such as Kullback-Leibler divergence (KL div), Normalized Scanpath Saliency (NSS), Correlation Coe ﬃ cient (CC) and similarity reveals that the proposed model is more adaptive in identifying the target region by suppressing other dominant objects.
Knowledge and Perceptions of Contraceptive Health Among College Students in Vietnam and the United States

Abstract Objectives The purpose of this study was to compare the knowledge, perceptions, and awareness of contraceptives among college students in Vietnam and the United States (US). Methods: The cross-sectional data were collected using a self-administered survey from January to March of 2019 in Vietnam and the US. There were 546 Vietnamese participants and 538 US participants. Nearly 70% of the participants were female. The average age was 20.37. The measures used included the knowledge, awareness and perceptions of contraceptive health. Results: US participants reported higher levels of knowledge, awareness and positive perceptions than those in Vietnam. The US and Vietnamese college students expressed different perspectives regarding the most effective and the most widely used contraceptive methods (e.g., condom vs IUD). Additionally, the results suggest that having a positive perception on contraceptive use can potentially mediate the relationship between knowledge and awareness. Conclusion: Social and cultural factors play a large role in shaping one’s attitude and awareness of contraceptives. Interpersonal relationships between students and their friends and families play a large role in both the amount and accuracy of the information they are given. The gap between knowing about contraceptives and using them, could be attributed to the sensitive nature of the topic. Public campaigns on other modern contraceptive choices and promotion on mass media may be a good solution.
Laser-induced fluorescence measurements of argon ion velocities near the sheath boundary of an argon–xenon plasma

The Bohm sheath criterion in single- and two-ion species plasma is studied with laser-induced fluorescence using a diode laser. Xenon is added to a low pressure unmagnetized dc hot filament argon discharge confined by surface multidipole magnetic fields. The Ar II transition at 668.614 nm is adopted for optical pumping to detect the fluorescence from the plasma and to measure the argon ion velocity distribution functions with respect to positions relative to a negatively biased boundary plate. The structures of the plasma sheath and presheath are measured by an emissive probe. The ion concentrations of the two-species in the bulk plasma are calculated from ion acoustic wave experiments. Results are compared with previous experiments of Ar–He plasmas in which the argon ions were the heavier ion species. Unlike the previous results, the argon speed is slower than its own Bohm velocity near the sheath–presheath boundary in the Ar–Xe plasma where argon ions are the lighter ion species. We argue that this result is consistent with the behaviour of the helium ion required by the generalized Bohm criterion in the previous experiments with Ar–He plasmas. Further, our results suggest that the measured argon ion speed approaches the ion sound speed of the system.
Treatment of Full and Partial Arches with Internal-Conical-Connection Dental Implants: Clinical Results after 5 Years of Follow-Up

The aim of the present investigation is to evaluate the implant therapy outcomes over a period of 5 years and to analyze several patient risk factors influencing the stability of the peri-implant tissues. Seventy-eight patients were consecutively treated between 2009 and 2017 and restored with implant-supported fixed prostheses. The following inclusion criteria were considered: partial or complete edentulism; residual bone volume of at least 3.3 mm in diameter and 8 mm in length; a favorable relationship between maxilla and mandible; at least a minimum 5 year follow-up for each implant included in the statistical analysis. Intraoral radiographs were taken at implant loading and every 12 months during the follow-up visits. They were subsequently stored on a personal computer and analyzed to determine the changes in bone level. Seventy-eight patients receiving 209 implants completed a minimum follow-up period of 5 years. One-hundred dental implants were inserted in the maxilla while 109 were placed in the mandible. Eleven (14.1%) out of 78 treated patients who received 29 (13.9%) dental implants were considered as drop-outs. On the whole, peri-implantitis was diagnosed in three implants. The average final pocket probing depth at implant level was 2.5 ± 1.2 mm. The average final bone loss after 5 years was 0.3 ± 0.4 mm, both at the mesial and distal aspect of the implant. The effects of the prosthesis type, sex and implant site did not statistically influence the marginal bone loss; on the contrary, a statistically significant difference regarding marginal bone loss was detected between smoker and non-smoker patients (p = 0.021). Implants with internal-conical abutment connection showed stable peri-implant bone levels at the medium-term follow-up. Nevertheless, further prospective long-term clinical studies are necessary to confirm these data.
Association of the CFTR gene with asthma and airway mucus hypersecretion

Introduction Asthma with airway mucus hypersecretion is an inadequately characterized variant of asthma. While several studies have reported that hypersecreting patients may carry genetic variants in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, many of those studies have been questioned for their numerous limitations and contradictory results. Objectives (1) To determine the presence of genetic variants of the CFTR gene in patients with asthma with and without airway mucus hypersecretion. (2) To identify the clinical, inflammatory and functional characteristics of the asthma phenotype with airway mucus hypersecretion. Method Comparative multicentre cross-sectional descriptive study that included 100 patients with asthma (39 hypersecretors and 61 non-hypersecretors). Asthmatic hypersecretion was defined as the presence of cough productive of sputum on most days for at least 3 months in 2 successive years. The patients were tested for fractional exhaled nitric oxide, spirometry, induced sputum cell count, total immunoglobulin E (IgE), peripheral blood eosinophil count, C-reactive protein, blood fibrinogen and blood albumin and underwent a skin prick test. Asthma control and quality of life were assessed by the Asthma Control Test and Mini Asthma Quality of Life questionnaires, respectively. Blood DNA samples were collected from the patients and next-generation sequencing using a MiSeq sequencer and the Illumina platform was used for the CFTR gene analysis. Results Genetic differences were observed in the c.1680-870T>A polymorphism of the CFTR gene, significantly more evident in hypersecretors than in non-hypersecretors: 78.94% vs. 59.32% in the majority allele and 21.05% vs. 40.67% in the minority allele (p = 0.036). Clinically, asthma hypersecretors compared to non-hypersecretors were older (57.4 years vs. 49.4 years; p = 0.004); had greater asthma severity (58.9% vs. 23.7%; p = 0.005); experienced greater airway obstruction (FEV1/FVC% 64.3 vs. 69.5; p = 0.041); had poorer asthma control (60% vs. 29%; p = 0.021); had lower IgE levels (126.4 IU/mL vs. 407.6 IU/mL; p = 0.003); and were less likely to have a positive prick test (37.5% vs. 68.85%; p = 0.011). Conclusion The results suggest that patients with asthma and with mucus hypersecretion (1) may have a different phenotype and disease mechanism produced by an intronic polymorphism in the CFTR gene (NM_000492.3:c.1680-870T>A), and (2) may have a poorer clinical outcome characterized by severe disease and poorer asthma control with a non-allergic inflammatory phenotype.
The psychoanalysis-neurosciences interface: A proposal for a hypothetical unification of psychoanalytic models

ABSTRACT Grotstein’s concept of projective transidentification led the author to reconsider the reasons that have led to the plurality of psychoanalytic models. The solution proposed is the existence of a fundamental frontal-occipital oscillatory dynamic, responsible for the projective-introjective dynamic that is at the basis of psychoanalytic theory and, at the same time, of the development and maintenance of mother–infant attunement. Such an oscillatory dynamic, according to this perspective, operates as a “bridge” between two seminal theoretical models of development – the psychoanalytic and the infant research model. A set of neurological hypotheses regarding how maternal interaction may act to modify the infant’s projective-introjective dynamic and general brain development is proposed. The different possible modifications of this dynamic offer an explanation of the variety and complexity of psychoanalytic models and the opportunity for a unitary approach, both clinical and theoretical. Given that it is considered to be the basis for cerebral activity, the oscillatory dynamic appears intrinsically connected with the default mode network’s functions of Self-cohesiveness and environmental monitoring, suggesting an important interface between psychoanalysis and the neurosciences.
Learning Will Continue

When Kansas school buildings were closed for the remainder of spring 2020, school leaders responded to ensure learning would continue for the P-12 500,000 students. Rapid change research provides a framework for looking at the response needed during this pandemic. The Kansas State Department of Education led efforts to pivot to remote learning. This article analyzes research data from all public and private schools related to challenges during this time. Access to technology, both devices and internet, remote delivery modes for teaching and learning, and use of paper packets are discussed as the State strengthens and moves forward.
Polymer escape through a nanopore

Free energy barrier and mean translocation time, τ, are calculated for the movement of a single Gaussian chain from one sphere to another larger sphere through a narrow pore. The potential interaction between the polymer and pore significantly modifies the entropic barrier landscape of translocation. As the pore length increases, the translocation process undergoes a transition from entropic barrier mechanism to a mechanism dominated by the pore–polymer interaction. This shift in mechanism leads to nonmonotonic dependence of τ on the pore length. Explicit formulas are derived for the dependence of τ on chain length, pore length, sizes of the donor and recipient spheres, strength of pore–polymer interaction, applied voltage, and electrochemical potential gradient for translocation. The calculated results provide guidance for tuning the rate of polymer translocation through narrow pores.
Basis of energy crop selection for biofuel production: Cellulose vs. lignin

ABSTRACT This paper investigates the suitability of Jerusalem artichoke (Helianthus tuberosus L.), fiber hemp (Cannabis sativa L.), energy sunflower (Helianthus annuus L.), Amur silver-grass (Miscanthus sacchariflorus), and energy grass cultivar (cv) Szarvasi-1 for biofuel production in Northern climatic conditions. Above ground biomass, bioethanol production yield, and methane production yield are used as indicators to assess the bio-energy potential of the culture. Results presented show that energy crops of Southern origin produce 30–70% less biomass than in the origin region. Nonetheless, both perennial and annual energy crops produce high above ground biomass yields (660–1280 g m–2) for Northern climatic conditions. Experimental results show that bioethanol yield is dependent on cellulose content of the biomass. The higher the cellulose content, the higher the bioethanol yield. The biogas production on the other hand, depends on lignin content. The lower the lignin content the higher the biogas yield. Therefore, the selection of the energy crop for bioethanol production should be based on high cellulose content, while for biogas production it should rather be based on the low lignin content.
THE EFFECTIVENESS OF ANIMAL ASSISTED THERAPY ON SOCIAL INTERACTION: A META-ANALYSIS

Animal-assisted therapy (AAT) is one of the non-pharmacological and complementary interventions. AAT has been practiced for many years and now a lot of progress are being made. However, the effect of AAT on social interaction is not well understood. The purpose of this meta-analysis was to present the best available evidence regarding the effects of AAT on social interaction including blood pressure, cognitive function, and communication. Researchers searched seven electronic databases for relevant articles published between 1984 and 2014. Data were collected using inclusion and exclusion criteria. The Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument was used to evaluate the quality of the identified articles.Six RCTs and three pseudorandomized controlled trial published within 1995-2011 with 281 participants had extractable data. The result of the meta-analysis indicated that AAT had an effect on increasing communication. The results were not statistically for blood pressure and cognitive function. There are a number of promising indications, in view of the limited number and quality of studies and the variation in results among studies. This review highlights the need for additional well-designed trials to draw conclusions that are more robust.

Factors Affecting the Rate of Breast Cancer; Role of Heavy Metals

Breast cancer is caused by uncontrolled growth of breast cells. It is more common in women as compared tothat in men. The breast cancer may be interlinked with the drinking of alcohol, smoking, sex, hormonal therapy, obesity,family history and age. Various epidemiologic studies suggest the role of metals e.g., nickel (Ni), zinc (Zn), arsenic(As),selenium (Se)and cadmium (Cd)as potential risk factors in breast cancer. Humans are exposed to these metals bymeans of drinking water, food and air. The oxidative theory suspects that the complexes formed from these metals invivo, near the location of DNA, catalyze the redox reactions which results in oxidation of DNA. The metals like arsenic(As), chromium (Cr), aluminum (Al), cadmium (Cd) and chromium (Cr)which exist in trace amount are considered ascarcinogens for organisms by IARC (International Agency for Research on Cancer). The carcinogenicity of these metalsmainly depends upon their chemical structure and oxidation states.
