Pre-exercise cryotherapy reduces myoglobin and creatine kinase levels after eccentric muscle stress in young women.

Introduction: The aim of this study was to investigate the effect of pre-exercise whole-body cryotherapy (WBC) on muscle damage indicators following eccentric treadmill exercise in young women. Methods: Twenty-seven participants underwent two 1-h downhill treadmill runs, replicating 60% of their maximal oxygen uptake, with a 4-week intermission for recovery and treatment application. In this intermission, one group underwent 20 sessions of WBC, delivered five times a week at -120°C for 3 min each, while the comparison group received no such treatment. Markers of muscle injury-serum myoglobin concentration, creatine kinase and lactate dehydrogenase activity and also uric acid, and cell-free DNA concentration-were measured before and after downhill runs. Results: The study observed a notable reduction in post-exercise myoglobin and CK levels in the WBC group after the second running session. Discussion: The results suggest that WBC can have a protective effects against muscle damage resulting from eccentric exercise.

Beyond Translation: Exploring the Stigmatization of Rainbow Works Translation Under Frame Theory.

Drawing on Goffman's frame theory, this study examines the attitudes of nine Chinese university teacher translators in translating rainbow works, ranging from hesitancy to resistance. The primary objective is to uncover the frames of stigmatization inherent in their negative attitudes toward rainbow works translation. The research clarifies the identities of perpetrators and victims in these frames leading to stigmatization. Findings indicate that various stigmatization events in rainbow works translation share a common feature-an unfavorable depiction of rainbow culture and related elements, encompassing the rainbow community, works, and translators. Perpetrators and victims vary across events, demonstrating diversity. The research interprets stigmatization in rainbow works translation at individual, institutional, and sociocultural levels. Providing a unique Chinese perspective, the study contributes to international understanding of stigmatization in a heteronormative society. It challenges traditional Chinese norms, advocates reevaluating identity labels for the rainbow community, and underscores the importance of addressing translators' circumstances in translating rainbow works within specific societal contexts.

The shifting roles of community health workers in the prevention and management of Noncommunicable disease during COVID-19 Pandemic: A scoping review.

Community Health Workers (CHWs) play a crucial role in the prevention and management of noncommunicable diseases (NCDs). The COVID-19 pandemic triggered the implementation of crisis-driven responses that involved shifts in the roles of CHWs in terms of delivering services for people with NCDs. Strategically aligning these shifts with health systems is crucial to improve NCD service delivery. The aim of this review was to identify and describe COVID-19-triggered shifting roles of CHWs that are promising in terms of NCD service delivery. We searched Ovid Medline, Embase, CINAHL, Web of Science, and CABI for Global Health for relevant articles published between Jan 1, 2020, and Feb 22, 2022. Studies that were conducted within a COVID-19 context and focused on the shifted roles of CHWs in NCD service delivery were included. We used PRISMA guidelines to report the findings. A total of 25 articles from 14 countries were included in this review. We identified 12 shifted roles of CHWs in NCD service delivery during COVID-19, which can be categorised in three dimensions: enhanced role of CHWs that include additional tasks such as medication delivery, extended roles such as the delivery of NCD services at household level and in remote communities; and enabled roles through the use of digital health technologies. Health and digital literacy of people with NCDs, access to internet connectivity for people with NCDs and the social and organizational context where CHWs work influenced the implementation of the shifted roles of CHWs. In conclusion, the roles of CHWs have shifted during COVID-19 pandemic to include the delivery additional NCD services at home and community levels, often supported by digital technologies. Given the importance of the shifting roles in the prevention and management of NCDs, adaptation and integration of these shifted roles into the routine activities of CHWs in the post-COVID period is recommended.

Social Protection and Foundational Cognitive Skills during Adolescence: Evidence from a Large Public Works Program.

Many low- and middle-income countries have introduced public works programs (PWPs) to fight poverty. This paper provides the first evidence that children from families who benefit from PWPs show increased foundational cognitive skills. The results, based on unique tablet-based data collected as part of a long-standing longitudinal survey, show positive associations between participation in the Productive Safety Net Programme (PSNP) in Ethiopia during childhood with long-term memory and implicit learning, and suggestive evidence for working memory. These associations appear to be strongest for children whose households were still PSNP participants in the year of data collection. Evidence suggests that the association with implicit learning may be operating partially through children's time reallocation away from unpaid labor responsibilities, while the association with long-term memory may in part be due to the program's success in remediating nutritional deficits caused by early-life rainfall shocks.

Clarity tubes as effective citizen science tools for monitoring wastewater treatment works and rivers.

Improved freshwater resource management requires the implementation of widespread, effective, and timely water quality monitoring. Conventional monitoring methods are often inhibited by financial, infrastructural, and human capacity limitations, especially in developing regions. This study aimed to validate the citizen-scientist-operated transparency or clarity tube (hereafter "clarity tube") for measuring water clarity as a proxy for total suspended solids (TSS) concentration, a critical quality metric in river systems and wastewater treatment works (WWTW) effluent in Southern Africa. Clarity tubes provided a relatively accurate and precise proxy for TSS in riverine lotic systems and WWTW effluent, revealing significant inverse log-linear relationships between clarity and TSS with r2 = 0.715 and 0.503, respectively. We demonstrate that clarity-derived estimates of TSS concentration (TSScde) can be used to estimate WWTW compliance with WWTW effluent TSS concentration regulations. The measurements can then be used to engage with WWTW management, potentially affecting WWTW performance. Overall, these findings demonstrate the usefulness of clarity tubes as low-cost, accessible, and easy-to-use citizen science tools for high spatial and temporal resolution water quality monitoring, not only in rivers in Southern Africa but also in WWTW effluent for estimating compliance, with strong global relevance to the sustainable development goals (SDGs).

Research on prediction of PPV in open-pit mine used RUN-XGBoost model.

The drill-blasting method is a commonly used mining technique in open-pit mines, and the peak particle velocity (PPV) caused by blasting vibrations is an important indicator for evaluating the rationality of blasting mining design parameters. To develop an effective PPV prediction model, a parameter self-optimizing RUN-XGBoost prediction model is implemented using the Runge-Kutta optimization algorithm (RUN) combined with extreme gradient boosting (XGBoost). The factors affecting the prediction of PPV, including maximum explosive (ME), total explosive (TE), blast center distance (BCD), blast hole depth (BHD), and height difference between the measurement location and the blast location (DH), are selected as the influencing indicators. 188 pieces of blasting operation data were measured at the RK open pit copper-cobalt mine. Then, the RUN-XGBoost prediction model for PPV is studied and compared with the Sadovsky empirical formula, traditional XGBoost model, PSO-XGBoost model, and some traditional machine learning models (Ridge, LASSO, SVM, and SVR) using R2, RMSE, VAF, MAE, and MBE as evaluation indicators for model prediction results. Finally, the Shapley Additive Explanations (SHAP) method is used to evaluate the contribution of different influencing indicators to the PPV prediction results. The results show that the RUN-XGBoost prediction model is significantly better than other machine learning models and the Sadovsky empirical formula in the prediction of PPV, further demonstrating that the RUN-XGBoost prediction model can handle the nonlinear features of multiple factors and provide a reliable, simple, and effective PPV prediction model, forming a rapid prediction and evaluation method for blasting vibrations in open-pit mining.

Verbal-Like Effects of Nonverbal Stimuli.

Stimuli produced by verbal responses (verbal stimuli) usually reveal something about the speakers who emitted them and about the environment where the verbal responses occurred (i.e., verbal stimuli can evoke in the listeners responses concerning the speakers and their environments). Verbal stimuli can also constitute supplementary stimulation that evokes responses which are already strong in the repertoire of some listeners or readers. Stimuli not produced by verbal responses (nonverbal stimuli), topographically similar to verbal stimuli, cannot reveal anything about speakers and their environments, but some of them can evoke responses that are already strong in the repertoire of some listeners or readers. Therefore, nonverbal stimuli allow one to distinguish clearly between the two functions of verbal stimuli. This article adopts a Skinnerian perspective and explores the implications of the supplementary function of stimuli for what is usually called understanding (and misunderstanding). Even when verbal stimuli are misunderstood, they can evoke verbal or nonverbal responses that are useful to the listeners. This effect can play a major role when it comes to aesthetic responses made to literary works, for example. Implications of the supplementary function of verbal stimuli for translations of ancient texts are also discussed. As supplementary stimulation, verbal stimuli can produce notable effects on the behavior of listeners and readers (even when the stimuli are misunderstood), although traditional mentalistic approaches to verbal behavior tend to neglect them.

The Top 50 Articles and Authors of the New Millennium in Psychiatry: A Bibliometric Analysis.

The field of psychiatry faces significant challenges in the new millennium, marked by a surge in mental health diagnoses coupled with barriers to accessing adequate care. Despite obstacles, notable advancements have been achieved throughout the field, including the release of DSM-5, the introduction of esketamine, and the development of innovative assessment tools. This study aims to comprehensively analyze recent advances in psychiatry by examining the top 50 most cited articles and authors since 2000, addressing a gap in the literature left by previous subfield-focused bibliometric studies. Utilizing the Web of Science (WOS) database, this bibliometric analysis examined all publications in psychiatric journals from January 1, 2000, to September 18, 2022. The top 50 most cited articles and authors were identified and characterized based on various metrics, including times cited, article type, and institutional affiliations. WOS extracted 699,005 articles, with authors from the United States contributing the highest number of publications. The top 50 articles spanned a variety of formats, with cross-sectional studies, new measures, literature reviews, and randomized controlled trials being the most prevalent. The American Journal of Psychiatry emerged as the leading journal, hosting eight of the top 50 articles. Among the top 50 authors, female representation was limited, comprising 24% of first authors and 22% overall. Institutional affiliations revealed a majority of top authors worked at universities affiliated with the top 40 NIH-funded departments of psychiatry, with those affiliated with Harvard University leading in authorship contributions. This study sheds light on recent advancements in psychiatry, emphasizing the underrepresentation of female authors and the prevalence of top authors affiliated with major NIH-funded programs. This bibliometric analysis provides a comprehensive overview of recent advances and the top recent contributors in the field, fostering a deeper understanding of the evolving landscape of psychiatry in the new millennium.

Fate and behaviour of Microplastics (> 25µm) within the water distribution network, from water treatment works to service reservoirs and customer taps.

Water treatment works have previously shown high efficiency in removing microplastics > 25 µm from raw source water. However, what is less well known is the extent to which microplastics of this size class are generated or lost within the water distribution network, particularly whether there is a greater presence in the customer tap than in the water treatment works outlet. This study focused on the presence of 21 different types of synthetic polymer particles with sizes larger than 25 µm examined through multiple rounds of sampling at outlets of water treatment works (WTW), service reservoirs (SR), and customer taps (CT) managed by seven different water companies in Britain. Nineteen different types of polymers were detected; their signature and concentration varied based on the round of sampling, the location within the water supply network, and the water company responsible for managing the supply. Among the polymers examined, polyamide (PA), polyethene terephthalate (PET), polypropylene (PP), and polystyrene (PS) were the most commonly found. Apart from PET having its highest concentration of 0.0189 microplastic per litre (MP/L) in the SR, the concentrations of the other three most frequent polymers (PS = 0.017 MP/L, PA = 0.0752 MP/L, PP= 0.1513 MP/L) were highest in the CT. The overall prevalence of this size of microplastics in the network is low, but there was a high variability of polymer types and occurrences. These spatial and temporal variations suggested that the MP in the distribution network may exist as a series of pulses. Given the presence and polymer types, the potential for some of the microplastics to originate from materials used in the water network and domestic plumbing systems cannot be ruled out. As found before, the absolute number of microplastics in the water distribution network remained extremely low.

A Second Fungal Outbreak in Castañar Cave, Spain, Discloses the Fragility of Subsurface Ecosystems.

Castañar is a cave with strict visitor control measures since it was open to public visits in 2003. However, in recent years, the cave suffered two fungal outbreaks, the first in 2008 and controlled by cleaning the contaminated sediments and subsequent closure of the cave until 2014. The cave was reopened but limited to a maximum of 450 visitors/year. Despite these restrictions on visit, the cave experienced a second outbreak in 2021, originating from the installation of a steel grating walkway, aiming at protecting the ground sediments from the visitors' footsteps. Here, we conducted an analysis using Next-Generation Sequencing and culture-dependent techniques to investigate the fungal communities related to the second outbreak and compare with those present before the cave suffered the outbreak. The results show that the most abundant fungi involved in the 2021 outbreak were already detected in 2020, and even in 2008 and 2009, although the main species that originating both outbreaks were different, likely due to the different carbon sources introduced into the cave.

COVID-19 on Food Insecurity in Hispanic/Latino Essential and Non-essential Workers.

INTRODUCTION: The COVID-19 pandemic's economic fallout has further exacerbated the health and well-being among Hispanics/Latinos, who maybe overrepresented in essential job industries and are vulnerable to experiencing food insecurity. This study explores whether the COVID-19 pandemic affected food security status differently among Latino/Hispanic essential and non-essential workers in the United States. METHODS: The COVID-19 Latino health cross-sectional survey was conducted and administered in person and virtually. Bivariate analyses and chi-square tests were performed to investigate the association between essential worker status and changes in food security status during the COVID-19 pandemic. All reported p-values were two-sided; p < 0.05 was considered statistically significant. RESULTS: Of the 869 Hispanic/Latino respondents, 393 (45%) were deemed essential workers, and 476 (55%) were non-essential workers. About 22% of essential workers reported a household income of less than $20,000, whereas 19% of non-essential workers had an income above $100,000. Half (54%) of essential workers reported food insecurity. Over one-third (35%) of essential and 22% of non-essential workers reported increased food insecurity during the COVID-19 pandemic. Moreover, there was a significant difference in food insecurity status between essential and non-essential Hispanic/Latino workers (p < 0.001). CONCLUSION: The results underscore the prevalence of food insecurity due to the COVID-19 pandemic and the need to create comprehensive food policies that address the lack of availability of adequate food among Hispanic/Latino essential workers who already face pandemic-related challenges.

Automatic Vertebral Rotation Angle Measurement of 3D Vertebrae Based on an Improved Transformer Network.

The measurement of vertebral rotation angles serves as a crucial parameter in spinal assessments, particularly in understanding conditions such as idiopathic scoliosis. Historically, these angles were calculated from 2D CT images. However, such 2D techniques fail to comprehensively capture the intricate three-dimensional deformities inherent in spinal curvatures. To overcome the limitations of manual measurements and 2D imaging, we introduce an entirely automated approach for quantifying vertebral rotation angles using a three-dimensional vertebral model. Our method involves refining a point cloud segmentation network based on a transformer architecture. This enhanced network segments the three-dimensional vertebral point cloud, allowing for accurate measurement of vertebral rotation angles. In contrast to conventional network methodologies, our approach exhibits notable improvements in segmenting vertebral datasets. To validate our approach, we compare our automated measurements with angles derived from prevalent manual labeling techniques. The analysis, conducted through Bland-Altman plots and the corresponding intraclass correlation coefficient results, indicates significant agreement between our automated measurement method and manual measurements. The observed high intraclass correlation coefficients (ranging from 0.980 to 0.993) further underscore the reliability of our automated measurement process. Consequently, our proposed method demonstrates substantial potential for clinical applications, showcasing its capacity to provide accurate and efficient vertebral rotation angle measurements.

Origins, Trends and Perspectives of Historical-Epistemological Research on Piaget.

In this paper, several points of view are adopted to present the research directions of contemporary Piagetian historiography. This article first notes the immensity of the secondary literature (20'000 texts) related to Piaget's work, between empirical and historical-epistemological works. In order to get a more precise idea, we carried out various analyses of the scope of influence of his work: on the 2000 keywords of the thesaurus of secondary literature from 1945 to 2012; on the reception of Piaget's idea in France between 1920 and 1940; and on the disciplines of insertion of a thousand works from his private library, which were dedicated to him. These analyses corroborate Piaget's multidisciplinary impact in the 20th century science and culture and indicate the existence of an international Piagetian movement, which has not yet been studied. The factors of production and the recent orientations of the secondary literature are then discussed, showing the changes in the historiography of the last 50 years. Finally, future research directions are outlined between the exploitation of unknown archives and the use of a digital edition of Piaget's work, which is currently underway.

Promotion of livelihood opportunities to address food insecurity in Rohingya refugee camps of Bangladesh.

The world is facing a tremendous problem in the form of food insecurity that is posing a great challenge to achieving sustainable development goal 2 of creating a hunger-free world. Refugees and displaced populations are particularly vulnerable to food insecurity and malnutrition, who lack any productive assets and depend on aid. Rohingya refugees, displaced from Myanmar and took refuge in Cox's Bazar, Bangladesh, live in a crowded unhealthy environment and are severely vulnerable to food insecurity and malnutrition. In our recent study, we found that only 21.6% of the households in Rohingya refugee camps had acceptable food security status. Interestingly, this study further revealed that acceptable food security status was significantly higher among the households that had some additional income aside from aid, compared to those relying on aid alone. This shows the importance of promoting livelihood opportunities to improve food security status among the camp dwellers. In this paper, we presented our views on promoting livelihood opportunities to address the overwhelming food insecurity crisis among the Rohingya refugees in Bangladesh.

Non-Aqueous Poly(dimethylsiloxane) Organogel Sponges for Controlled Solvent Release: Synthesis, Characterization, and Application in the Cleaning of Artworks.

Polydimethylsiloxane (PDMS) organogel sponges were prepared and studied in order to understand the role of pore size in an elastomeric network on the ability to uptake and release organic solvents. PDMS organogel sponges have been produced according to sugar leaching techniques by adding two sugar templates of different forms and grain sizes (a sugar cube template and a powdered sugar template), in order to obtain materials differing in porosity, pore size distribution, and solvent absorption and liquid retention capability. These materials were compared to PDMS organogel slabs that do not contain pores. The sponges were characterized by Fourier-transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR) and compared with PDMS slabs that do not contain pores. Scanning electron microscopy (SEM) provided information about their morphology. X-ray micro-tomography (XMT) allowed us to ascertain how the form of the sugar templating agent influences the porosity of the systems: when templated with sugar cubes, the porosity was 77% and the mean size of the pores was ca. 300 µm; when templated with powdered sugar, the porosity decreased to ca. 10% and the mean pore size was reduced to ca. 75 µm. These materials, porous organic polymers (POPs), can absorb many solvents in different proportions as a function of their polarity. Absorption capacity, as measured by swelling with eight solvents covering a wide range of polarities, was investigated. Rheology data established that solvent absorption did not have an appreciable impact on the gel-like properties of the sponges, suggesting their potential for applications in cultural heritage conservation. Application tests were conducted on the surfaces of two different lab mock-ups that simulate real painted works of art. They demonstrated further that PDMS sponges are a potential innovative support for controlled and selective cleaning of works of art surfaces.

Factors associated with stigma and manifestations experienced by Indian health care workers involved in COVID-19 management in India: A qualitative study.

Healthcare personnel who deal with COVID-19 experience stigma. There is a lack of national-level representative qualitative data to study COVID-19-related stigma among healthcare workers in India. The present study explores factors associated with stigma and manifestations experienced by Indian healthcare workers involved in COVID-19 management. We conducted in-depth interviews across 10 centres in India, which were analysed using NVivo software version 12. Thematic and sentiment analysis was performed to gain deep insights into the complex phenomenon by categorising the qualitative data into meaningful and related categories. Healthcare workers (HCW) usually addressed the stigma they encountered when doing their COVID duties under the superordinate theme of stigma. Among them, 77.42% said they had been stigmatised in some way. Analyses revealed seven interrelated themes surrounding stigma among healthcare workers. It can be seen that the majority of the stigma and coping sentiments fall into the mixed category, followed by the negative sentiment category. This study contributes to our understanding of stigma and discrimination in low- and middle-income settings. Our data show that the emergence of fear of the virus has quickly turned into a stigma against healthcare workers.

Increasing Trunk Mass Evokes Lower Extremity Biomechanical Plasticity during Stair Descent.

The purpose of this study was to investigate the influence of simulated changes in body mass on lower extremity joint work and relative joint contributions during stair descent. Ten healthy recreationally active college-age participants performed five stair descent trials in each of five loading conditions: no added load and with an additional 5%, 10%, 15% and 20% of their body weight. Three-dimensional ankle, knee and hip joint powers were calculated using a six degree-of-freedom model in Visual3D (C-Motion Inc., Germantown, MD, USA). Sagittal plane joint work was calculated as the joint power curve integrated with respect to time during the period between initial contact and toe off. Prism 9.0 (GraphPad Inc., San Diego, CA) was used to perform univariate 1 × 5 repeated measures analyses of variance to determine the effect of added mass on absolute and relative joint work values for total and for each lower extremity joint independently. Increasing added mass was associated with greater total lower extremity negative work during the stair descent task (p < 0.001). At the ankle, increasing added mass was associated with increasing magnitudes of negative joint work. Increasing added mass was associated with greater relative contributions of the ankle and reduced knee contributions to total negative lower extremity joint work (p = 0.014 and p = 0.006). The current findings demonstrated increases in ankle joint contributions to total lower extremity work while knee joint contributions to total lower extremity work were reduced in response to increasing added mass.

Salinity spatial patterns in Mediterranean coastal areas: The legacy of historical water infrastructures.

Mediterranean coastal areas have been occupied and developed intensively for a long time facing issues related to agricultural production, urbanization, tourism, preservation of natural resources often linked to salinity. This article explores the relationship between historical land planning and water management, and current soil and water salinity to gain insights into future projections. Soil samples (1185) were collected in a coastal plain of 114 km2 in the south of France and saturated paste extract Electrical Conductivity (ECsp) was deduced from 1:5 dilution. Soil salinity exhibits a wide range of variation (from 0.54 to 113.1 mS cm-1) and spatial patterns. ECsp is significantly different among soil types, higher at depth than at the surface and influenced by the distance to ancient water infrastructures (Pettitt test). Surface water and shallow groundwater samples were collected for trace element concentrations and Oxygen (18O/16O) isotope ratio measurements. The geochemical signatures indicate a mixture between surface freshwater and seawater, reveal the presence of over-salted seawater and a stratification of salinity from the surface to the depth. Results suggest that groundwater is the source of soil salinity, and illustrate the long-term impact of old water infrastructures. Less saline soils are found near the freshwater supply channel (constructed from 15th to 18th), while more saline soils are located near drainage channels. The presence of over-salted water reflects temporal evolution of the plain over the last few centuries (initially under seawater, gradually filled in, presence of ponds and salt works that have now disappeared). The current soil salinity patches continue to be a visible reminder of this evolution. The trend towards desalinization of the plain over the last few centuries has been made possible by massive freshwater inflows, which are now under threat due to the general decrease of water resources availability.

A review of _urban water networks management using GIS.

Use of computer technology is common in the construction since the 90's .Geographical Information System is a very useful technology in any data driven industry. The present paper reviews on the application and management of water works through GIS. GIS Data can be categorized as spatial and non-spatial data, which can be stored, manipulated, analysed and displayed with multiple users which can help in comprehensive solutions in a systematic way. GIS application is very common in construction industry, construction safety, flood studies, pipeline management which includes water works and sewerage. Project management through GIS is different from GIS based projects, the review briefs about the difference between the two. The pipe network management includes planning, designing, and management of the network, the planning is done using Remote sensing, photogrammetry drone or field survey method depending on the budget and objectives of the project. The designing of the network is done in GIS or separate application environment. The final step is the operations and management of the network which is in GIS.
