A SEARCH FOR RADIO TRANSIENTS IN VERY LARGE ARRAY ARCHIVAL IMAGES OF THE 3C 286 FIELD

We present a search for radio transients (RTs) in the field of the bright radio source 3C 286 using archival observations from the Very Large Array (VLA). These observations span 23 years and include 1852 epochs at 1.4 GHz in the C and D configurations. We find no transients in the field. The sensitivity of the observations is limited by dynamic range effects in the images. At large flux densities (>0.2 Jy), single-epoch observations provide a strong limit on the transient surface density. At flux densities near the dynamic range threshold, we use the requirement that transient sources must appear in consecutive epochs to be confirmed as real. This sets the sensitivity at low flux densities to transient durations of τ ∼ 1 day, while τ>1 minute for high flux densities. At 70 mJy, we find a 2σ limit on the surface density Σ < 3 × 10−3 deg−2. At 3 Jy, we find a 2σ limit Σ < 9 × 10−4 deg−2. A future systematic search of the VLA archives can provide one to two orders of magnitude more sensitivity to RTs.
HMGB1-activatied NLRP3 inflammasome induces thrombocytopenia in heatstroke rat

Background Thrombocytopenia, an early common complication in heatstroke (HS), has been widely considered as a mortality predictor of HS. The mechanism underlying thrombocytopenia in HS remains unknown. It is not known whether NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome is activated in HS platelet, which, in turn, induces platelet activation and thrombocytopenia. This study tried to clarify the activation of the NOD-like receptor signaling pathway under HS conditions and investigate its roles in mediating HS-induced thrombocytopenia. Methods Rat HS models were established in a certain ambient temperature and humidity. Platelets, isolated from blood, were counted and CD62P, an index of platelet activation, was measured by flow cytometry in all rats. The colocalization of NLRP3 inflammasome in platelet was detected by confocal fluorescence microscopy. Mitochondrial-derived reactive oxygen species (ROS) was detected using the molecular probes. Plasma HMGB1 and IL-1β levels were measured by ELISA. Results Platelet activation, showed by upregulated CD62P, and thrombocytopenia were observed in HS rats. HS activated the NLRP3 inflammasome, which was induced by elevated levels of ROS, while the upregulated CD62P and thrombocytopenia triggered by NLRP3 inflammasome were attributed to the high mobility group box protein 1 (HMGB1) inplasma. Moreover, inhibition of the NOD-like receptor signaling pathway in rats with HS suppressed platelet activation and the decline of platelet count. Similar results were obtained when the receptor toll-like receptor 4 (TLR4)/advanced glycation end product (RAGE) was blocked. Conclusions The NOD-like receptor signaling pathway induces platelet activation and thrombocytopenia in HS rats. These findings suggested that the NLRP3 inflammasome might be the potential target for HS treatment.
The Impact of Personality Types on Students’ Speaking Ability : A Quasi-Experimental Study

Personality can be one of the internal factors that have an impact on students’ ability in language learning. The present study investigated the impact of personality types on their ability in writing English. There are two types of personalities studied: Extrovert and Introvert. The research is quasi-experiment. Students at grade XI SMAN 6 Kerinci engage in the study, whereas only two classes selected as samples (experimental class and control class). Students were given a personality questionnaire to recognize their personality types. Then, the speaking test carries out in each class in order to know the student's ability in writing. The data are analysed by using t-test. The finding of hypotheses testing proves that the value of t-observed is 19.43 which is higher than t-table 4.301, so H0 is rejected and H1 is accepted. Hence, there is a significant impact on students’ personalities to their speaking ability. Students with extrovert personalities have better speaking than students with introvert personality.
Effectiveness of Whole-Body High-Intensity Interval Training on Health-Related Fitness: A Systematic Review and Meta-Analysis

Due to its versatility, whole-body high-intensity interval training (WB-HIIT) can be proposed to the general population and patients to improve health-related fitness. However, its effectiveness compared to traditional aerobic continuous or interval trainings has yet to be determined. A search of four electronic databases was conducted. Studies reporting the effects of WB-HIIT on cardiorespiratory fitness (CRF), fat mass, fat-free mass, musculoskeletal fitness and metabolic risk factors were included. Standardized mean differences (SMD) between WB-HIIT and no exercise or traditional aerobic trainings were calculated. A meta-regression assessed the effect of total training time on the different outcomes. Twenty-two studies were included in the systematic review and nineteen in the meta-analysis. Compared to no exercise, WB-HIIT improves CRF (SMD: 0.75; 95%CI: 0.28, 1.23; p < 0.001), fat-free mass (SMD: 0.38; 95%CI: 0.11, 0.65; p < 0.001), fat mass (SMD: 0.40; 95%CI: 0.09, 0.72; p < 0.001) and musculoskeletal fitness (SMD: 0.84; 95%CI: 0.61, 1.08; p < 0.001). Compared to other aerobic trainings, WB-HIIT has a lower effect on CRF (SMD: −0.40; 95%CI: −0.70, −0.11; p = 0.007), a similar effect on fat-free mass (SMD: −0.04; 95%CI: −0.44, 0.35; p = 0.8) and fat mass (SMD: −0.07; 95%CI: −0.39, 0.25; p = 0.7), and a larger effect on musculoskeletal fitness (SMD: 0.42; 95%CI: 0.14, 0.71; p = 0.003). WB-HIIT overall effect and specific effect on CRF and fat mass were associated with total training time. The systematic review did not provide evidence of metabolic risk improvement. Despite a slightly lower effect on CRF, WB-HIIT is equally effective as traditional aerobic trainings to improve body composition and more effective to enhance musculoskeletal fitness, which is essential for execution of daily tasks.
Impact of an action-oriented environmental education course on students’ environmental awareness

Abstract This study explores the impact of an action-oriented environmental education course on students’ environmental awareness, with 53 college students divided into experimental (N = 27) and control (N = 26) groups. Both groups participated in similar learning activities; however, the experimental group further recorded the amount of waste discharged into the environment by people around them for one and a half months (2 days/week). Students in the experimental group showed a significant difference in six of seven environmental awareness dimensions after this course. These results confirm that an action-oriented environmental education course has a positive effect on changing an individual’s awareness of the environment.
Oral-Periodontal Health and Cytokine Storm: Correlation and Preventive Measures

Coronavirus disease 19 (COVID-19) has taken the world by storm, affecting all age groups alike and presenting a plethora of signs and symptoms. Showcasing a high mortality rate, cytokine storm is identified as one of the most common culprits for death in affected individuals. In patients undergoing severe complications in the form of intubations and intensive care unit (ICU) admissions, increased cytokine levels have again been identified as a significant factor, indicating their substantial role in disease outcomes. Periodontitis, which is identified as a silent pandemic, is the most common oral disease that is found in individuals. The increased accumulations of plaques and calculus are the main causative agents, stimulating inflammatory cells in the periodontal tissue, leading to cytokine release. Individuals with the removable or fixed dental prosthesis are at increased risk of contracting fungal infections, which are also identified as increasing the cytokine levels and worsening an individual’s condition contracted with COVID-19. This review focuses on oral hygiene measures and scientifically proven aids that can be used by patients at home for reducing oral cytokine levels and the risk of COVID-19 related complications, thereby sensitizing them at a time when elective dental procedures are discouraged and patients are devoid of professional dental intervention. Mechanical removal of plaques and calculus cannot be substituted with auxiliary aids, but it is important that adjunct practices be adopted for efficient hygiene. Toothbrush hygiene should also be practiced to prevent disease progression and transmission. Adherence to these recommendations is not only required for healthy or infected individuals but also for viral infection recovered patients to avoid the possible risk of developing the black fungus infection.
Synthesis and physical properties of metal-doped picene solids

We report electronic structure and physical properties of metal doped picene as well as selective synthesis of the phase exhibiting 18 K superconducting transition. First, Raman scattering is used to characterize the number of electrons transferred from the dopants to picene molecules. The charge transfer leads to a softening of Raman scattering peaks, which enables us to determine the number of transferred electrons. From this we have identified that three electrons are transferred to each picene molecule in the superconducting doped-picene solids. Second, we report the pressure dependence of Tc in 7 and 18 K phases of K3picene. The 7 K phase shows a negative pressure-dependence, while the 18 K phase exhibits a positive pressure-dependence which cannot be understood with a simple phonon mechanism of BCS superconductivity. Third, we report a new synthesis method for superconducting K3picene by a solution process with monomethylamine, CH3NH2. This method enables one to prepare selectively the K3picene sample exhibiting 18 K superconducting transition. The discovery of suitable way for preparing K3picene with Tc = 18 K may facilitate clarification of the mechanism of superconductivity.
Thirteen cancers associated with HIV infection in a Black South African cancer patient population (1995‐2016)

South Africa's HIV epidemic has evolved over time in terms of numbers of people living with HIV, access to antiretroviral treatment (ART) and age. These changes have profoundly influenced local cancer patterns. The Johannesburg Cancer Study has, over a period of 22 years (1995‐2016), recruited over 20 000 incident black cancer patients who consented to provide answers to a questionnaire and blood samples (serum, DNA). This has presented a unique opportunity to examine the evolving association of HIV with cancer in Africa. We used logistic regression models to explore case‐control associations between specific cancers and HIV, using participants with non‐infection related cancers as controls. Using data of 20 835 cancer patients with confirmed HIV status, we found the following cancers to be associated with HIV: Kaposi's sarcoma (ORadj; 95%CI): (99.1;72.6‐135.1), non‐Hodgkin lymphoma (11.3;9.3‐13.6), cervical cancer (2.7;2.4‐3.0), Hodgkin lymphoma (3.1;2.4‐4.2), cancer of the eye/conjunctiva (18.7;10.1‐34.7), anogenital cancers (anus [2.1;1.4‐3.2], penis [5.4;2.7‐10.5], vulva [4.8;3.5‐6.4], vagina [5.5;3.0‐10.2]), oropharyngeal cancer (1.6;1.3‐1.9), squamous cell carcinoma of the skin (3.5;2.4‐4.9), melanoma (2.0;1.2‐3.5) and cancer of the larynx (1.7;1.3‐2.4). Kaposi's sarcoma odds ratios increased from the pre‐ART (1995‐2004) to the early ART (2005‐2009) period but declined in the late ART (2010‐2016) period. Odds ratios for cancers of the eye/conjunctiva, cervix, penis and vulva continued to increase in recent ART periods. Our study confirms the spectrum of HIV‐associated cancers found in other African settings. The odds ratios of conjunctival and HPV‐related cancers continue to rise in the ART era as the HIV positive population ages.
The Use of Alloderm® Coverage to Reinforce Tissues in Two-Stage Tissue Expansion Placement in the Subcutaneous (Prepectoral) Plane: A Prospective Pilot Study

Purpose: Two-stage tissue expander (TE) to implant breast reconstruction is commonly performed by plastic surgeons. Prepectoral implant placement with acellular dermal matrix (ADM, e.g., AlloDerm®) reinforcement is evidenced by minimal postoperative pain. However, the same is not known for TE-based reconstruction. We performed this study to explore the use of complete AlloDerm® reinforcement of breast pocket tissues in women undergoing unilateral or bilateral mastectomies followed by immediate, two-stage tissue expansion in the prepectoral plane. Methods: Patients (n = 20) aged 18-75 years were followed prospectively from their preoperative consult to 60 days post-TE insertion. The pain visual analog scale (VAS), Patient Pain Assessment Questionnaire, Subjective Pain Survey, Brief Pain Inventory-Short Form (BPI-SF), postoperative nausea and vomiting (PONV) survey, BREAST-Q Reconstruction Module, and short-form 36 (SF-36) questionnaires were administered. Demographic, intraoperative, and 30- and 60-day complications data were abstracted from medical records. After TE-to-implant exchange, patients were followed until 60 days postoperatively to assess for complications. Results: Pain VAS and BPI-SF pain interference scores returned to preoperative values by 30 days post-TE insertion. Static and moving pain scores from the Patient Pain Assessment Questionnaire returned to preoperative baseline values by day 60. The mean subjective pain score was 3.0 (0.5 standard deviation) with seven patients scoring outside the standard deviation; none of these seven patients had a history of anxiety or depression. Median PONV scores remained at 0 from postoperative day 0 to day 7. Patient-reported opioid use dropped from 89.5% to 10.5% by postoperative day 30. BREAST-Q: Sexual well-being scores significantly increased from preoperative baseline to day 60 post-TE insertion. Changes in SF-36 physical functioning, physician limitations, emotional well-being, social functioning, and pain scores were significantly different from preoperative baseline to day 60 post-TE insertion. Five participants had complications within 60 days post-TE insertion. One participant experienced a complication within 60 days after TE-to-implant exchange. Conclusions: We describe pain scores, opioid usage, patient-reported outcomes data, and complication profiles of 20 consecutive patients undergoing mastectomy followed by immediate, two-stage tissue expansion in the prepectoral plane. We hope this study serves as a baseline for future research.
Microgravity-Related Changes in Bone Density and Treatment Options: A Systematic Review

Space travelers are exposed to microgravity (µg), which induces enhanced bone loss compared to the age-related bone loss on Earth. Microgravity promotes an increased bone turnover, and this obstructs space exploration. This bone loss can be slowed down by exercise on treadmills or resistive apparatus. The objective of this systematic review is to provide a current overview of the state of the art of the field of bone loss in space and possible treatment options thereof. A total of 482 unique studies were searched through PubMed and Scopus, and 37 studies met the eligibility criteria. The studies showed that, despite increased bone formation during µg, the increase in bone resorption was greater. Different types of exercise and pharmacological treatments with bisphosphonates, RANKL antibody (receptor activator of nuclear factor κβ ligand antibody), proteasome inhibitor, pan-caspase inhibitor, and interleukin-6 monoclonal antibody decrease bone resorption and promote bone formation. Additionally, recombinant irisin, cell-free fat extract, cyclic mechanical stretch-treated bone mesenchymal stem cell-derived exosomes, and strontium-containing hydroxyapatite nanoparticles also show some positive effects on bone loss.
What drives older adults to continue working after official retirement age?

The need to ensure the economic wellbeing and quality of life of those who reach the official retirement age is a matter of concern in the world of social services and in social policy making. Since some working older adults may be forced to retire when they reach the official retirement age while others retire voluntarily, the study is based on a dedicated survey among 508 persons who retired both willingly and unwillingly for good after reaching the official retirement age and 437 persons who continued working uninterruptedly. The findings show that the odds of staying on the job after retirement age are contingent on the socio-demographic and health-related characteristics of the older adult. Furthermore, the economic predictors of remaining in the labour force after retirement age depend on how strongly the older adult wishes to retire. Those who continue working after retirement age and those who retire willingly are undifferentiated in the level of financial support that they give others. Comparing older adults who continue working uninterruptedly with those who retire unwillingly, the chances of being among the former are higher among those who are better off before reaching retirement age. These results emphasise the need to extend welfare and financial-support policies to older adults who are forced to retire, in order to minimise the economic blow that this path to retirement causes.
Factors Associated with Cardiac/Pericardial Injury among Blunt Injury Patients: A Nationwide Study in Japan

The lack of established diagnostic criteria makes diagnosing blunt cardiac injury difficult. We investigated the factors associated with blunt cardiac injury using the Japan Trauma Data Bank (JTDB) in a multicenter observational study of blunt trauma patients conducted between 2004 and 2018. The primary outcome was the incidence of blunt cardiac/pericardial injury. Multivariable logistic regression analysis was used to identify factors independently associated with blunt cardiac injuries. Of the 228,513 patients, 1002 (0.4%) had blunt cardiac injury. Hypotension on hospital arrival (adjusted odds ratio (AOR) 4.536, 95% confidence interval (CI) 3.802–5.412), thoracic aortic injury (AOR 2.722, 95% CI 1.947–3.806), pulmonary contusion (AOR 2.532, 95% CI 2.204–2.909), rib fracture (AOR 1.362, 95% CI 1.147–1.618), sternal fracture (AOR 3.319, 95% CI 2.696–4.085). and hemothorax/pneumothorax (AOR 1.689, 95% CI 1.423–2.006)) was positively associated with blunt cardiac injury. Regarding the types of patients, car drivers had a higher rate of blunt cardiac injury compared to other types of patients. Driving a car, hypotension on hospital arrival, thoracic aortic injury, pulmonary contusion, rib fracture, sternal fracture, and hemothorax/pneumothorax were positively associated with blunt cardiac injury.
“I’m Not Doing It for the Company”: Examining Employee Volunteering Through Employees’ Eyes

This article contributes to research on employee volunteering (EV) by focusing on the experiences of individuals to address the current overemphasis upon collective organizational outcomes. Drawing on qualitative research with employees and corporate social responsibility managers across seven companies, it demonstrates why employees’ experiences are central to understanding the complex mechanisms that link EV with organizational outcomes. The article reveals how both positive and negative organizational outcomes are influenced by the complex relationship between personal motivations and employees’ volunteering experiences—within their organization and within their community—combined with their broader reflexive interpretation of their employing organization and its values.
Comparison of the Classification Results Accuracy for CT Soft Tissue and Bone Reconstructions in Detecting the Porosity of a Spongy Tissue

The aim of the study was to compare the accuracy of the classification pertaining to the results of two types of soft tissue and bone reconstructions of the spinal CT in detecting the porosity of L1 vertebral body spongy tissue. The dataset for each type of reconstruction (high-resolution bone reconstruction and soft tissue reconstruction) included 400 sponge tissue images from 50 healthy patients and 50 patients with osteoporosis. Texture feature descriptors were calculated based on the statistical analysis of the grey image histogram, autoregression model, and wavelet transform. The data dimensional reduction was applied by feature selection using nine methods representing various approaches (filter, wrapper, and embedded methods). Eleven methods were used to build the classifier models. In the learning process, hyperparametric optimization based on the grid search method was applied. On this basis, the most effective model and the optimal subset of features for each selection method used were determined. In the case of bone reconstruction images, four models achieved a maximum accuracy of 92%, one of which had the highest sensitivity of 95%, with a specificity of 89%. For soft tissue reconstruction images, five models achieved the highest testing accuracy of 95%, whereas the other quality indices (TPR and TNR) were also equal to 95%. The research showed that the images derived from soft tissue reconstruction allow for obtaining more accurate values of texture parameters, which increases the accuracy of the classification and offers better possibilities for diagnosing osteoporosis.
A search for near-infrared counterparts of two faint neutron star X-ray transients: XMMU J174716.1-281048 and SAX J1806.5-2215

We present our near-infrared (NIR) imaging observations of two neutron star low-mass X-ray binaries XMMU J174716.1−281048 and SAX J1806.5−2215 obtained using the PANIC instrument on the 6.5-metre Magellan telescope and the WIYN High-Resolution Infrared Camera instrument on the 3.5-metre WIYN telescope, respectively. Both sources are members of the class of faint to very faint X-ray binaries and undergo very long X-ray outburst, hence classified as ‘quasi-persistent X-ray binaries’. While XMMU J174716.1−281048 was active for almost 12 yr between 2003 and 2015, SAX J1806.5−2215 has been active for more than 5 yr now since 2011. From our observations, we identify two NIR stars consistent with the Chandra X-ray error circle of XMMU J174716.1−281048. The comparison of our observations with the United Kingdom Infrared Telescope (UKIRT) Galactic plane observations taken during the same outburst, colour–colour diagram analysis and spectral energy distribution suggest that both stars are probably a part of the field population and are likely high-mass stars. Hence possibly neither of the two stars is a true NIR counterpart. For the faint X-ray binary SAX J1806.5−2215 during its current outburst, we detected an NIR star in our K-band WIYN observations consistent with its Chandra error circle. The identified NIR star was not detected during the UKIRT observations taken during its quiescent state. The comparison of two observations suggests that there was an increase in flux by at least one magnitude of the detected star during our observations, and hence suggests the detection of the likely counterpart of SAX J1806.5−2215.
Rapid Depletion of Nitrogen Applied to Kentucky Bluegrass Turf

The depletion of N applied to a moderately N-deficient Kentucky bluegrass (Poa pratensis L.) turf was measured using a soil sampling procedure. Nitrogen as either Ca(NO3)2 or (NH4)2SO4 was applied in solution at 5 g N/m2 and washed into the thatch and soil with an additional 0.3 cm of water. Both N forms were located primarily in the thatch and upper 1 cm of soil. The was present in the soil solution, while the was mainly exchangeable (86%). The concentrations of and in the soil solution were 452 and 56 μg N/ml, respectively, in the upper 1 cm of soil. Depletion of both and from the turf was very rapid, with 70% to 80% of the applied N disappearing during the first 24 hr. Essentially all of the applied N was depleted by 48 hr. Results using (l5NH4)2SO4 indicate that ≈75% of the depletion is attributable to absorption by the turf. Similar results were obtained following fertilization of perennial ryegrass (Lolium perenne L.), tall fescue (Festuca arundinaceae Schreb.), and creeping bentgrass (Agrostis palustris Huds.).
