Our primary objective was to examine the impact of acquiescent responding on empathy measures. We selected the Affective and Cognitive Measure of Empathy (ACME) as the measure for this case study due to its composition—the affective dissonance scale consists solely of items that are semantically reversed relative to the empathy construct, while the resonance scale comprises mostly semantically positive items—which raises questions about whether the distinction between resonance and dissonance factors is authentic or merely an effect of acquiescence. Utilizing data from 2,489 Brazilian adults, we explored ACME's factor structure by testing various models, both with and without acquiescence control. We also examined the invariance of model parameters, including those for acquiescence, across self-reported sex and assessed the influence of acquiescence on the associations between ACME's factors and external measures. Our findings indicated that while acquiescence does affect ACME, the resonance and dissonance factors are not exclusively a result of this bias. Nevertheless, it was demonstrated that both the items and their associations with external measures are significantly impacted by acquiescence. These results underscore the crucial need to account for response biases in empathy evaluations and in other psychological assessment measures. [ABSTRACT FROM AUTHOR]

The objectives of this study were (1) to investigate the effects of the preovulatory follicle (POF) size on the accuracy of Doppler‐based early pregnancy detection, and (2) to determine whether the removal of PGF2α (PGF) treatment during the resynchronisation protocol would affect fertility in beef cows. In Experiment 1, Nelore suckling cows (n = 224) were enrolled in an estradiol‐progesterone–based timed artificial insemination (TAI) protocol. At TAI, cows were separated based on the range of POF diameters, as follows: ≤11.0 mm (n = 50), 11.1–12.9 mm (n = 64), 13.0–14.4 mm (n = 62) and ≥14.5 mm (n = 48). On day 22 after TAI, the corpus luteum (CL) blood flow (CLBF) of all cows was examined by colour Doppler ultrasonography to diagnose nonpregnant cows. The cows with the largest POF had the greatest positive predictive value (88.6%; 31 of 35) and diagnostic accuracy (91.7%; 44 of 48). In Experiment 2, Nelore cows (n = 233) were subjected to the same TAI protocol. Fourteen days after TAI, all cows were started on a resynchronisation protocol. Cows diagnosed as nonpregnant based on CLBF, on day 22, received 0.5 mg estradiol cypionate intramuscular (im) and were assigned to receive either 150 μg of PGF (PGF; n = 50) or 2 mL of saline (control; n = 47). Cows treated with PGF had a P/AI of 30.0% compared with a 48.9% P/AI in controls (p = 0.06). Our findings demonstrate that the POF size affects the accuracy of a CLBF‐based early pregnancy diagnosis and that the removal of PGF treatment from the resynchronisation protocol tended to increase P/AI of the second TAI.

Plant pathogens are constantly under selection pressure for host resistance adaptation. Soybean cyst nematode (SCN, Heterodera glycines) is a major pest of soybean primarily managed through resistant cultivars; however, SCN populations have evolved virulence in response to selection pressures driven by repeated monoculture of the same genetic resistance. Resistance to SCN is mediated by multiple epistatic interactions between Rhg (for resistance to H. glycines) genes. However, the identity of SCN virulence genes that confer the ability to overcome resistance remains unknown. To identify candidate genomic regions showing signatures of selection for increased virulence, we conducted whole genome resequencing of pooled individuals (Pool‐Seq) from two pairs of SCN populations adapted on soybeans with Peking‐type (rhg1‐a, rhg2, and Rhg4) resistance. Population differentiation and principal component analysis‐based approaches identified approximately 0.72–0.79 million SNPs, the frequency of which showed potential selection signatures across multiple genomic regions. Chromosomes 3 and 6 between population pairs showed the greatest density of outlier SNPs with high population differentiation. Conducting multiple outlier detection tests to identify overlapping SNPs resulted in a total of 966 significantly differentiated SNPs, of which 285 exon SNPs were mapped to 97 genes. Of these, six genes encoded members of known stylet‐secreted effector protein families potentially involved in host defence modulation including venom‐allergen‐like, annexin, glutathione synthetase, SPRYSEC, chitinase, and CLE effector proteins. Further functional analysis of identified candidate genes will provide new insights into the genetic mechanisms by which SCN overcomes soybean resistance and inform the development of molecular markers for rapidly screening the virulence profile of an SCN‐infested field.

Background: Dementia is a leading factor in the institutionalization of older adults. Informal caregivers' desire to institutionalize (DI) their care recipient with dementia (PwD) is a primary predictor of institutionalization. This study aims to develop a prediction model for caregivers' DI by mining data from an eHealth platform in a high-prevalence dementia country. Methods: Cross-sectional data were collected from caregivers registering on isupport-portugal.pt. One hundred and four caregivers completed the Desire to Institutionalize Scale (DIS) and were grouped into DI (DIS score ≥ 1) and no DI (DIS score = 0). Participants completed a comprehensive set of sociodemographic, clinical, and psychosocial measures, pertaining to the caregiver and the PwD, which were accounted as model predictors. The selected model was a classification tree, enabling the visualization of rules for predictions. Results: Caregivers, mostly female (82.5%), offspring of the PwD (70.2), employed (65.4%), and highly educated (M 15 years of schooling), provided intensive care (Mdn 24 h. week) over a median course of 2.8 years. Two-thirds (66.3%) endorsed at least one item on the DIS (DI group). The model, with caregivers' perceived stress as the root of the classification tree (split at 28.5 points on the Zarit Burden Interview) and including the ages of caregivers and PwD (split at 46 and 88 years, respectively), as well as cohabitation, employed five rules to predict DI. Caregivers scoring 28.5 and above on burden and caring for PwD under 88 are more prone to DI than those caring for older PwD (rules 1–2), suggesting the influence of expectations on caregiving duration. The model demonstrated high accuracy (0.83, 95%CI 0.75, 0.89), sensitivity (0.88, 95%CI 0.81, 0.95), and good specificity (0.71, 95%CI 0.56, 0.86). Conclusions: This study distilled a comprehensive range of modifiable and non-modifiable variables into a simplified, interpretable, and accurate model, particularly useful at identifying caregivers with actual DI. Considering the nature of variables within the prediction rules, this model holds promise for application to other existing datasets and as a proxy for actual institutionalization. Predicting the institutional placement of PwD is crucial for intervening on modifiable factors as caregiver burden, and for care planning and financing. [ABSTRACT FROM AUTHOR]

Background: Crowding has been a longstanding issue in emergency departments. To address this, a fast-track system for avoidable patients is being implemented in the Paediatric Emergency Department where our study is conducted. Our goal is to develop an optimized Decision Support System that helps in directing patients to this fast track. We evaluated various Machine Learning models, focusing on a balance between complexity, predictive performance, and interpretability. Methods: This is a retrospective study considering all visits to a university-affiliated metropolitan hospital's PED between 2014 and 2019. Using information available at the time of triage, we trained several models to predict whether a visit is avoidable and should be directed to a fast-track area. Results: A total of 507,708 visits to the PED were used in the training and testing of the models. Regarding the outcome, 41.6% of the visits were considered avoidable. Except for the classification made by triage rules, i.e. considering levels 1,2, and 3 as non-avoidable and 4 and 5 as avoidable, all models had similar results in model's evaluation metrics, e.g. Area Under the Curve ranging from 74% to 80%. Conclusions: Regarding predictive performance, the pruned decision tree had evaluation metrics results that were comparable to the other ML models. Furthermore, it offers a low complexity and easy to implement solution. When considering interpretability, a paramount requisite in healthcare since it relates to the trustworthiness and transparency of the system, the pruned decision tree excels. Overall, this paper contributes to the growing body of research on the use of machine learning in healthcare. It highlights practical benefits for patients and healthcare systems of the use ML-based DSS in emergency medicine. Moreover, the obtained results can potentially help to design patients' flow management strategies in PED settings, which has been sought as a solution for addressing the long-standing problem of overcrowding.

This study evaluated the relationship between CL features assessed by ultrasound (luteal tissue area and blood flow, BF) or rectal palpation (size), uterine tone (UT), plasma progesterone (P4) concentration on Day 7 (D7) and subsequent pregnancy outcomes in bovine embryo recipients. A total of 163 cows and heifers were included in this study. The expected day of ovulation after the synchronization protocol was designated as D0. On D7, ovaries and uterus were examined by ultrasonography and rectal palpation, and subjective scores (1–3 scale) were assigned for CL size, area and BF, and for UT. Blood samples were collected for further P4 analysis. Each embryo recipient then received a grade I frozen–thawed in vivo‐produced blastocyst, which was transferred to the uterine horn ipsilateral to the CL. Pregnancy diagnosis was performed on D35, and the results were retrospectively compared with the assigned scores for CL and UT. We observed a significant (p <.02) interaction between CL size and UT, with a progressive increase in the likelihood of pregnancy for recipients bearing a large CL among those with turgid UT. Ultrasound scoring of the CL using B‐mode and Doppler‐mode did not significantly predict pregnancy rates on D35 (p <.6 and p <.5, respectively). However, logistic regression analysis revealed a trend towards a quadratic effect (p <.08 and p <.06) indicating that the probability of pregnancy varied according to the area of luteal tissue and P4 concentrations, respectively. No significant (p >.05) association was found between the probability of pregnancy and the BF area of the CL. In summary, UT before embryo transfer may reflect successful recipient synchronization. Elevated P4 levels, assessed by CL size, may offset uterine contractility, mitigating adverse effects. Additionally, the CL area may be more important than its vascularization area when evaluating recipients D7 after ovulation. [ABSTRACT FROM AUTHOR]

- Abstract
In an increasingly aging and overweight population, osteoporosis and type 2 diabetes (T2DM) are major public health concerns. T2DM patients experience prejudicial effects on their bone health, affecting their physical capacity. Exercise in hypoxia (EH) and a low-carbohydrate diet (LCD) have been suggested for therapeutic benefits in T2DM, improving bone mineral content (BMC) and glycemic control. This study investigated the effects of EH combined with an LCD on body composition and functional and physiologic capacity in T2DM patients. Older T2DM patients (n = 42) were randomly assigned to the following groups: (1) control group: control diet + exercise in normoxia; (2) EH group: control diet + EH; (3) intervention group: LCD + EH. Cardiopulmonary tests (BRUCE protocol), body composition (DEXA), and functional capacity (6MWT, handgrip strength) were evaluated. Body mass index (kg/m
2 ) and body fat (%) decreased in all groups (p < 0.001). BMC (kg) increased in all groups (p < 0.001) and was significantly higher in the EH and EH + LCD groups (p < 0.001). VO2peak improved in all groups (p < 0.001), but more so in the hypoxia groups (p = 0.019). Functional capacity was increased in all groups (p < 0.001), but more so in the EH group in 6MWT (p = 0.030). EH with and without an LCD is a therapeutic strategy for improving bone mass in T2DM, which is associated with cardiorespiratory and functional improvements. [ABSTRACT FROM AUTHOR]- Published

Astrocytes are ubiquitous in the brain and spinal cord and display a complex morphology important for the local interactions with neighboring cells, resulting in the modulation of circuit function. Thus, studies focusing on astrocyte physiology in the healthy and diseased brain generally present analyses of astrocytic structure. The labeling method used to visualize the astrocytic structure defines the morphological level to observe and may vary depending on the anatomical sub-regions. The method choice may significantly affect our understanding of their structural diversity. The main goal of this work was to identify a straightforward and efficient protocol for labeling and reconstructing a detailed astrocytic structure to apply and validate in different brain tissue preparations across laboratories. For that, we explored different tissue processing protocols before GFAP labeling to determine the most effective method for reconstructing astrocytic backbones in the mouse hippocampus. Our results show that the reconstruction of astrocytic structure in vibratome sections labeled by free-floating immunofluorescence protocol provides a more practical method to achieve a higher level of detail and arbor complexity in astrocyte backbone reconstruction. Free-floating immunofluorescence labeling is the most reliable method for obtaining better antibody penetration and more detailed astrocyte structure. Finally, we also show that introducing an antigen retrieval step appears useful for visualizing more complete structural details. [ABSTRACT FROM AUTHOR]

Introduction: In recent years, research in educational contexts has pointed to the role of grit as a variable related to various positive outcomes, including life satisfaction. Academic adaptation seems vital for the success of academic life in college students. Considering university as an important life context for people pursuing higher education, what is the mediating effect of academic adaptation? This study proposed a mediation model to examine the mediating effect of academic adaptation in the relationship grit and life satisfaction. Methods: A sample of 413 undergraduate Brazilian students, age ranging from 18 to 71 years (M = 27.30; SD = 10.20). A correlation analysis was performed between the variables and the following mediation model was tested: Grit (independent variable), academic adaptation (mediating variables) and life satisfaction (dependent variables). Results: Mediation analysis indicated that academic adaptation mediated around 46.80% for the factor of consistency of interests and 40.90% of the relationship with perseverance of effort. Thus, the greater the grit of the university student, the greater the grit, which leads to better satisfaction with life. Discussion: In recent years, research in educational contexts has pointed to the role of grit as a variable related to various positive outcomes. The findings elucidated that grit in academic context could benefit students’ adaptation process, and the university’s responsibility to improve its students’ softskills, not only for the future stage after university, but also during the student’s schooling.

This paper analyzes Mia Couto's short story "O dia em que explodiu Mabata-bata" [The day Mabata-bata exploded] and its adaptation by Sol de Carvalho's film Mabata Bata. Through an analysis of both versions, this study aims to understand how Couto's narrative was recreated and transfigured in the film adaptation. The film adaptation of the story employs a blend of images and additional text to extend the verbal dimensions of the original story, thus creating a new experience. It establishes affinities with the original story and introduces new elements that add to the narrative's depth and complexity. The adaptation of the story in the film provides an opportunity to examine the decolonial perspective of the nation's history, portraying the symbolic metamorphosis during the civil war (1977–1992). By analyzing both the short story and the film, this study highlights the pivotal role of literature and cinema in fostering a Mozambique "de-linking" identity through language, religion and traditions.

- Abstract
Establishing new somatic cell cultures has raised significant attention as an effective and convenient way to preserve genetic samples for different applications. Although many lines have been established in model animals, none derived from six-banded armadillo species is currently available. We report the successful isolation and characterization of fibroblasts from six‐banded armadillos, evaluating the cell quality after extended culture and cryopreservation. Initially, we collected ear skin from five captive adult individuals and identified fibroblast lines by morphology, karyotyping, and immunophenotyping assays. The isolated fibroblasts were evaluated after several passages (fourth, seventh, and tenth passages) and cryopreservation by slow freezing. Cell morphology, viability, metabolism, proliferative activity, mitochondrial membrane potential, and apoptosis levels were analyzed. The skin explants had great adhesion, and cell outgrowth could be seen after 3–6 d. The cells were verified as fibroblasts at the fourth passage by vimentin expression and normal karyotype (2n = 58). The viability remained high (> 87%) and constant from the fourth to the tenth passage (p > 0.05). The passages did not change the cell morphology and metabolic and growth rates. Moreover, cryopreservation did not affect most evaluated parameters; post-thawed cells maintained their viability, growth, metabolism, and apoptosis levels. Nevertheless, cryopreservation increased mitochondrial membrane permeability and cell population doubling time compared to non-cryopreserved cells (p < 0.05). In summary, viable fibroblasts can be obtained from six-banded armadillo skin while conserving their quality as the number of passages increases and featuring few changes after cryopreservation.

- Abstract
Fibroblast cycle synchronization in G
0 /G1 is an essential step for nuclear reprogramming by cloning or induced cells to pluripotency. Considering the diversity among rodents and the ecological and scientific importance of these animals, we compared the contact inhibition, serum starvation, and 10 µM of roscovitine as methods of synchronization of red-rumped agouti fibroblasts. The effects of each protocol were evaluated on the percentage of cycle phase, morphology, viability, and apoptosis levels. The results showed that culturing the cells to serum starvation for 24 h (75.9%), 48 h (81.6%), 72 h (86.2%), 96 h (84.0%), and 120 h (83.7%) yielded a significantly higher percentage of cells arrested in the G0 /G1 (P < 0.05) phase than cells not subjected to any cell cycle synchronization method (31.4%). Also, this effect was not different between the times of 48 and 120 h (P > 0.05). A similar response was observed for cells cultured with roscovitine for 12 h (86.9%), 24 h (74.8%), and 48 h (81.7%), with a higher percentage of synchronized cells in G0 /G1 compared to cells not submitted to any synchronization treatment (52.2%). Nevertheless, this effect was best evidenced at 12 h (P < 0.05). Also, the contact inhibition for 24–120 h could not synchronize cells in G0 /G1 , with values ranging from 70.9 to 77.9% (P > 0.05). Moreover, no difference was observed for morphology, viability, and apoptosis levels in any synchronization method (P > 0.05). Therefore, serum starvation is as efficient as roscovitine on cycle synchronization in G0 /G1 of red-rumped agouti fibroblasts. [ABSTRACT FROM AUTHOR]- Published

With the increasing influx of patients and frequent overcrowding, the adoption of a valid triage system, capable of distinguishing patients who need urgent care, from those who can wait safely is paramount. Hence, the aim of this study is to evaluate the validity of the Paediatric Canadian Triage and Acuity Scale (PaedCTAS) in a Portuguese tertiary hospital. Furthermore, we aim to study the performance and appropriateness of the different surrogate severity markers to validate triage. This is a retrospective study considering all visits to the hospital's Paediatric Emergency Department (PED) between 2014 and 2019. This study considers cut-offs on all triage levels for dichotomization in order to calculate validity measures e.g. sensitivity, specificity and likelihood ratios, ROC curves; using hospital admission, admission to intensive care and the use of resources as outcomes/markers of severity. Over the study period there were 0.2% visits triaged as Level 1, 5.7% as Level 2, 39.4% as Level 3, 50.5% as Level 4, 4.2% as Level 5, from a total of 452,815 PED visits. The area under ROC curve was 0.96, 0.71, 0.76, 0.78, 0.59 for the surrogate markers: "Admitted to intensive care"; "Admitted to intermediate care"; "Admitted to hospital"; "Investigations performed in the PED" and "Uses PED resources", respectively. The association found between triage levels and the surrogate markers of severity suggests that the PedCTAS is highly valid. Different surrogate outcome markers convey different degrees of severity, hence different degrees of urgency. Therefore, the cut-offs to calculate validation measures and the thresholds of such measures should be chosen accordingly. [ABSTRACT FROM AUTHOR]

Background matching and disruptive coloration are common camouflage strategies in nature, but few studies have accurately measured their protective value in living organisms. Amazon's Bark praying mantises exhibit colour patterns matching whitish and greenish-brown tree trunks. We tested the functional significance of background matching and disruptive coloration of different praying mantis morphospecies (white, grey and green) detected by DNA barcoding. Through image analysis, avian visual models and field experiments using humans as potential predators, we explored whether the background occupation of mantises provides camouflage against predation. Data were obtained for individuals against their occupied tree trunks (whitish or greenish-brown) and microhabitats (lichen or bryophyte patches), compared to non-occupied trunks. White and grey mantises showed lower colour contrasts against occupied trunks at the scale of tree trunk, with no differences in luminance contrasts. Conversely, green mantises showed lower colour and luminance contrasts against microhabitats and also exhibited high edge disruption against greenish-brown trunks. The camouflage of white and green mantis models against colour-matching trunks increased search time and reduced encounter distance of human predators. We highlight the importance of camouflage strategies at different spatial scales to enhance individual survival against predators. Specifically, we present a stunning study system to investigate the relationship of phylogenetically related species that use camouflage in sympatry. [ABSTRACT FROM AUTHOR]

In this paper we complete the computation of the next-to-leading (NLO) electroweak (EW) corrections to on-shell and non-loop-induced Higgs decays. Our calculations are implemented in the code EWsHDECAY which also includes the relevant QCD corrections. Performing an extensive parameter scan in the model and including all relevant theoretical and experimental single- and di-Higgs as well as DM constraints, we obtain a viable parameter sample. We find that current DM constraints are able to test the model in DM mass regions where collider searches are not sensitive. The relative EW corrections turn out to be large for scenarios with relatively large couplings, threshold effects or small leading-order (LO) widths. Otherwise, they are of typical EW size and can amount up to about 20–25%. The theory uncertainty derived from the change of the renormalization scheme dependence then is of a few per cent. While the NLO corrections applied in the constraints due to single- and di-Higgs searches impact the validity of specific parameter points, the overall shape of the allowed parameter region is not yet sensitive to the EW corrections. This picture will change with further increased experimental precision in the future and necessitates precise predictions on the theory side as presented in this paper. [ABSTRACT FROM AUTHOR]

A good oral health status is mostly dependent on good oral hygiene habits, which knowingly impacts systemic health. Although controversial, chemical oral antiseptics can be useful in adjunct use to mechanical dental plaque control techniques in the prevention and management of local and overall health and well-being. This review aims to revisit, gather and update evidence-based clinical indications for the use of the most popular oral antiseptics, considering different types, microorganism targets and effectiveness in order to establish updated clinical recommendations.

Physical activity levels are typically undesirably low in chronic kidney disease patients, especially in those undergoing haemodialysis, and particularly on dialysis days. Intradialytic exercise programmes could be a solution to this issue and have been reported to be safe and relatively easily implemented in dialysis clinics. Nevertheless, such implementation has been failing in part due to barriers such as the lack of funding, qualified personnel, equipment, and patient motivation. Intradialytic aerobic exercise has been the most used type of intervention in dialysis clinics. However, resistance exercise may be superior in eliciting potential benefits on indicators of muscle strength and mass. Yet, few intradialytic exercise programmes have focused on this type of intervention, and the ones which have report inconsistent benefits, diverging on prescribed exercise intensity, absent or subjective load progression, equipment availability, or exercise supervision. Commonly, intradialytic resistance exercise interventions use free weights, ankle cuffs, or elastic bands which hinder load progression and exercise intensity monitoring. Here, we introduce a recently developed intradialytic resistance exercise device and propose an accompanying innovative resistance exercise training protocol which aims to improve the quality of resistance exercise interventions within dialysis treatment sessions.

In recent decades, significant changes have driven the advancement of agricultural production systems in Brazil. The objective of this study is to analyze the efficiency and transformation of the agricultural production system in the Ibirapuitã Environmental Preservation Area (EPA) through nitrogen input and output flows. Methodologically, the approach is considered mixed, consisting of a case study and based on quantitative and qualitative techniques. Flowcharts and indicators were elaborated to evaluate nitrogen flows over time. The results were confirmed through semi-structured interviews. The results indicated that production based on economic efficiency is one of the main factors transforming the livestock system. The transformation of the production system into livestock did not reduce nitrogen flows. Productive and economic indicators reaffirm the transformation and volatility of livestock systems under economic and political contexts, even in an environmental protection unit.

- Abstract
This study proposed a moderated mediation model to examine the mediating effect of school subjective well-being and moderating effect of perceived social support in the relationship between bullying victimization and mathematics academic performance. A sample of 428 adolescents from northeast Brazil, ages ranging from 12 to 19 years (M = 14.88; SD = 1.70), students from middle and high school. Mediation analysis indicated that positive affects at school completely mediated the relationship been bullied and math grades. Moderated mediation analysis further indicated that the overall perceived social support moderates the mediating pathway of bullying on school subjective well-being. The findings elucidated that positive feelings in the school context could benefit students' learning process, and the school's responsibility to improve the quality of social support provided to victims of bullying.

Spinocerebellar ataxia type 3 (SCA3) is a rare neurodegenerative disease caused by an abnormal polyglutamine expansion within the ataxin-3 protein (ATXN3). This leads to neurodegeneration of specific brain and spinal cord regions, resulting in a progressive loss of motor function. Despite neuronal death, non-neuronal cells, including astrocytes, are also involved in SCA3 pathogenesis. Astrogliosis is a common pathological feature in SCA3 patients and animal models of the disease. However, the contribution of astrocytes to SCA3 is not clearly defined. Inositol 1,4,5-trisphosphate receptor type 2 (IP
3 R2) is the predominant IP3 R in mediating astrocyte somatic calcium signals, and genetically ablation of IP3 R2 has been widely used to study astrocyte function. Here, we aimed to investigate the relevance of IP3 R2 in the onset and progression of SCA3. For this, we tested whether IP3 R2 depletion and the consecutive suppression of global astrocytic calcium signalling would lead to marked changes in the behavioral phenotype of a SCA3 mouse model, the CMVMJD135 transgenic line. This was achieved by crossing IP3 R2 null mice with the CMVMJD135 mouse model and performing a longitudinal behavioral characterization of these mice using well-established motor-related function tests. Our results demonstrate that IP3 R2 deletion in astrocytes does not modify SCA3 progression. [ABSTRACT FROM AUTHOR]- Published

Individuals with chronic kidney disease (CKD) have a systemic inflammatory state. We assessed the effects of exercise on inflammatory markers in individuals with CKD. An electronic search was conducted, including MEDLINE. Experimental clinical trials that investigated the effects of exercise on inflammatory markers in individuals with CKD at all stages were included. Meta-analyses were conducted using the random-effects model and standard mean difference (SMD). Subgroup analyses were performed for resistance, aerobic, and combined exercise interventions. Twenty-nine studies were included in the meta-analyses. Exercise interventions showed significant reductions in C-reactive protein (CRP) (SMD: −0.23; 95% CI: −0.39 to −0.06), interleukin (IL)-6 (SMD: −0.35; 95% CI: −0.57, −0.14), and tumor necrosis factor-alpha (TNF-α) (SMD: −0.63, 95% CI: −1.01, −0.25) when compared with the controls. IL-10 levels significantly increased (SMD: 0.66, 95% CI: 0.09, 1.23) with exercise interventions. Resistance interventions significantly decreased CRP (SMD: −0.39, 95% CI: −0.69, −0.09) and TNF-α (SMD: −0.72, 95% CI: −1.20, −0.23) levels, while increasing IL-10 levels (SMD: 0.57, 95% CI: 0.04, 1.09). Aerobic interventions only significantly reduced IL-6 levels (SMD: −0.26, 95% CI: −0.51, −0.01). No significant changes in any inflammatory markers were observed with combined exercise interventions. Exercise interventions are effective as an anti-inflammatory therapy in individuals with CKD compared to usual care control groups. Resistance interventions seem to promote greater anti-inflammatory effects. [ABSTRACT FROM AUTHOR]

Background: Kidney failure patients receiving haemodialysis experience protein‐energy wasting, muscle mass loss and physical function impairment. Intradialytic exercise interventions seem to modify these features, but they are often not implemented as a clinical routine. Objective: To investigate the feasibility of implementing a supervised intradialytic resistance training programme as a clinical routine for patients receiving short daily haemodialysis. Design: A prospective longitudinal study. Participants: Eighteen patients in a supervised intradialytic resistance training programme for 8 months. Measurements: It consisted of a warm‐up, lower‐ and upper‐limb resistance exercises and a cool‐down. Patients performed the resistance training during the first half of haemodialysis, twice a week, supervised by exercise physiologists and physiotherapists. The feasibility was assessed by the total and partial adherences, the reasons for refusing or for not exercising and the intradialytic complications. Results: From a total of 953 potential exercise sessions, 759 were performed, with a 79.6% adherence rate. In the first 9 weeks, the adherence rate was 86.6% and the lowest rate was in the 19–27 weeks (73.5%). The main intradialytic complication during exercise sessions was hypotension (n = 31; 4.1%). The highest number of complications was reported during the first 9 weeks (n = 27; 9.1%). The main reasons for refusing or for not performing the intradialytic exercise sessions were clinical complications previous to exercise time (n = 63; 32.5%) and self‐reported indisposition (n = 62; 32.0%). Conclusions: The intradialytic resistance training programme, supervised by exercise physiologists and physiotherapists, had very low complications, achieved a high long‐term adherence rate and showed to be feasible as a clinical routine for patients receiving short daily haemodialysis.

- Abstract
The loss of wild biodiversity has prompted the development of cryobanks, such as those of somatic cells. This is the reality of Pumas, wild felids of ecological importance that suffer from anthropogenic actions, population decline, and subsequent loss of genetic diversity. Somatic cell banks are a strategy for conserving population diversity. We compared different concentrations and types of intracellular cryoprotectants (dimethyl sulfoxide, DMSO; ethylene glycol, EG) associated with 0.2 M of sucrose (SUC) in the cryopreservation of the somatic cells of captive Pumas. The cells were cryopreserved by slow freezing with different solutions containing Dulbecco's modified Eagle's medium with 10% fetal bovine serum and varying concentrations of DMSO and EG in the absence or presence of SUC. The cells were analyzed for morphological characteristics, viability, proliferative activity, metabolic activity, and apoptosis levels. Cells maintained similar fusiform morphology before and after cryopreservation. There was no difference in viability, regardless of the reduction in the concentration and type of intracellular cryoprotectants and sucrose. Similarly, proliferative activity, metabolic activity, and apoptosis levels were not altered by the composition of the cryoprotectants. In summary, we demonstrate that reducing the concentration of DMSO or EG ensures adequate cryopreservation of Puma somatic cells, regardless of the presence of SUC. Highlights: Reducing the concentration of dimethyl sulfoxide or ethylene glycol ensures adequate cryopreservation of Puma somatic cells, regardless of sucrose.Apoptosis levels were not altered by the composition of the cryoprotectants.These results represent an advance for establishing somatic resource banks in zoos, aiming at conserving Pumas or phylogenetically close individuals.

Chronic Kidney Disease (CKD) is a global health burden with high mortality and health costs. CKD patients exhibit lower cardiorespiratory and muscular fitness, strongly associated with morbidity/mortality, which is exacerbated when they reach the need for renal replacement therapies (RRT). Muscle wasting in CKD has been associated with an inflammatory/oxidative status affecting the resident cells' microenvironment, decreasing repair capacity and leading to atrophy. Exercise may help counteracting such effects; however, the molecular mechanisms remain uncertain. Thus, trying to pinpoint and understand these mechanisms is of particular interest. This review will start with a general background about myogenesis, followed by an overview of the impact of redox imbalance as a mechanism of muscle wasting in CKD, with focus on the modulatory effect of exercise on the skeletal muscle microenvironment.

The prevalence of low bone mineral density (LBMD) in people with chronic kidney disease (CKD) remains unknown. We identified a high prevalence of LBMD in CKD population. Thus, public health strategies should include efforts to prevent, early detect, and manage LBMD in CKD patients, especially in patients undergoing kidney replacement therapy. Mineral and bone disorders are common among patients with CKD, which affects bone mineral density. We conducted a systematic review and meta-analysis to estimate the prevalence of low bone mineral density (LBMD) in adults with CKD. We searched MEDLINE, EMBASE, Web of Science, CINAHL, and LILACS databases from inception to February 2021. Observational studies that reported the prevalence of LBMD in adults with CKD stages 3a–5D were included. The LBMD was defined according to the World Health Organization criterion (T-score ≤ − 2.5). Random-effect model meta-analyses were used to estimate the pooled prevalence of LBMD. Meta-regressions and subgroup analyses were conducted for stages of CKD, dialysis modality, gender, bone sites and morphology, and geographical region. This study was registered in PROSPERO, number CRD42020211077. One-hundred and fifty-three studies with 78,092 patients were included. The pooled global prevalence of LBMD in CKD was 24.5% (95% CI, 21.3 − 27.8%). Subgroup analyses indicated a higher prevalence of LBMD in dialysis patients (30%, 95% CI 25 − 35%) compared with non-dialysis CKD patients (12%, 95% CI 8 − 16%), cortical bone sites (28%, 95% CI 23 − 35%) relative to trabecular sites (19%, 95% CI 14 − 24%), while similar estimates in the European and the Asiatic continents (26%, 95% CI 21 − 30% vs 25%, 95% CI 21 − 29). The prevalence of LBMD in CKD patients is high, particularly in those undergoing dialysis and in cortical bone sites. Therefore, efforts to early diagnosis and management strategies should be implemented in clinical routine for an epidemiological control of LBMD in CKD patients. [ABSTRACT FROM AUTHOR]

SUMMARY: The soybean Rpp1 locus confers resistance to Phakopsora pachyrhizi, causal agent of rust, and resistance is usually dominant over susceptibility. However, dominance of Rpp1‐mediated resistance is lost when a resistant genotype (Rpp1 or Rpp1b) is crossed with susceptible line TMG06_0011, and the mechanism of this dominant susceptibility (DS) is unknown. Sequencing the Rpp1 region reveals that the TMG06_0011 Rpp1 locus has a single nucleotide‐binding site leucine‐rich repeat (NBS‐LRR) gene (DS‐R), whereas resistant PI 594760B (Rpp1b) is similar to PI 200492 (Rpp1) and has three NBS‐LRR resistance gene candidates. Evidence that DS‐R is the cause of DS was reflected in virus‐induced gene silencing of DS‐R in Rpp1b/DS‐R or Rpp1/DS‐R heterozygous plants with resistance partially restored. In heterozygous Rpp1b/DS‐R plants, expression of Rpp1b candidate genes was not significantly altered, indicating no effect of DS‐R on transcription. Physical interaction of the DS‐R protein with candidate Rpp1b resistance proteins was supported by yeast two‐hybrid studies and in silico modeling. Thus, we conclude that suppression of resistance most likely does not occur at the transcript level, but instead probably at the protein level, possibly with Rpp1 function inhibited by binding to the DS‐R protein. The DS‐R gene was found in other soybean lines, with an estimated allele frequency of 6% in a diverse population, and also found in wild soybean (Glycine soja). The identification of a dominant susceptible NBS‐LRR gene provides insight into the behavior of NBS‐LRR proteins and serves as a reminder to breeders that the dominance of an R gene can be influenced by a susceptibility allele. Significance Statement: Most resistance genes are inherited dominantly, although the present study serves as a reminder to breeders that the dominance of an R gene can be influenced by a susceptibility allele. The study identified a susceptible NBS‐LRR allele that can negate the dominance of the Rpp1‐mediated resistance to Asian soybean rust. The results support suppression of resistance occurring at the protein level, possibly through the interaction between the susceptible protein and the resistance protein. [ABSTRACT FROM AUTHOR]

To examine the validity, and the relative and absolute within-day reliability of the TGlittre in chronic kidney disease patients undergoing hemodialysis (HD). Thirty HD patients (52 ± 12 years) undertook the TGlittre twice on a single day, in a cross-sectional design. For validation purposes, participants TGlittre performance and accelerometry-based physical activity were correlated. Intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimal detectable change (MDC) were determined to assess within-day reliability. There was a moderate correlation between TGlittre performance and moderate to vigorous physical activity (r= −0.587; p= 0.001). The relative reliability of the test showed an ICC of 0.96. For the absolute reliability, the SEM was 13.05 s (0.22 min), and the MDC was 36.17 s (0.60 min). TGlittre performance is associated with moderate to vigorous physical activity in HD patients, highlighting that those with higher levels of physical activity are likely to perform better on the TGlittre. Additionally, TGlittre shows a good to excellent intra-rater reliability and a low SEM. An MDC value was established. Patients on hemodialysis have a low physical capacity and often struggle to simply complete their physical activities of daily living. The TGlittre is a tool for assessing functional capacity through completion of multiple physical activities of daily living and can be easily applied in a clinical setting. TGlittre is a valid test that elicit reliable physiological, hemodynamic, and physical performance responses in HD patients. [ABSTRACT FROM AUTHOR]

Oral diseases are highly prevalent worldwide. Recent studies have been supporting a potential bidirectional association of oral diseases with systemic noncommunicable diseases (NCDs). Available evidence supports that people with NCDs have a greater prevalence of oral diseases particularly those with limited ability of oral self-care. Regarding the reverse relationship, the lines of evidence pointing out NCDs as putative risk factors for oral diseases have increased significantly but not with a consistent agreement. This umbrella review of meta-analyses appraises the strength and validity of the evidence for the association between oral health and systemic health (registered at PROSPERO, ID: CRD42022300740). An extensive search included systematic reviews that have provided meta-analytic estimates on the association of oral diseases with NCDs. The overall strength of evidence was found to be unfavorable and with methodological inconsistencies. Twenty-eight NCDs were strongly associated with oral diseases. Among those NCDs are five types of cancer, diabetes mellitus, cardiovascular diseases, depression, neurodegenerative conditions, rheumatic diseases, inflammatory bowel disease, gastric helicobacter pylori, obesity, and asthma. According to fail-safe number statistics, the evidence levels are unlikely to change in the future, indicating a fairly robust consistency. Previous studies have supported a potential bidirectional association between oral diseases and systemic noncommunicable diseases (NCDs) Here the authors perform an umbrella review of meta-analyses for the association between oral health and NCDs, and report that 27 NCDs were associated with oral disease, however, the overall strength of evidence was found to be unfavorable and with methodological inconsistencies.

Introduction: Kidney transplant patients (KT) are at high risk for severe COVID‐19 and presented attenuated antibody responses to vaccination when compared to immunocompetent individuals. Torquetenovirus (TTV) has recently gained attention as a potential surrogate marker of the net state of immunosuppression. We evaluated the association between pre‐vaccination TTV viral load and anti‐spike total antibody response to SARS‐CoV‐2 vaccination in KT. Material and Methods: The 114 adult KT recipients enrolled in this prospective single‐center cohort study received two doses of SARS‐CoV‐2 mRNA BNT162b2 vaccine. Serum samples were collected immediately before vaccination at the days when patients received both the first (T0) and the second dose (T1) and 16–45 days after the second dose (T2). Primary endpoint was the development of anti‐spike total antibodies after vaccination. Demographic, clinical, and laboratorial parameters were compared between patients with and without detectable SARS‐CoV‐2 antibodies at T2. Results: Ninety‐nine patients (86.8%) were naïve for SARS‐CoV‐2 before vaccination. Fifty‐six (56.6%) patients developed anti‐spike total antibodies at T2. The use of mTOR inhibitors was associated with a favorable response (p =.005); conversely, mycophenolic acid (MPA) was associated with a negative response (p =.006). In a multivariable model, the presence of TTV at T0 ≥ 3.36 log10 cp/ml was associated with unfavorable vaccine response (OR: 5.40; 95% CI: 1.47–19.80; p =.011), after adjusting for age and eGFR at T0. Conclusions: Higher TTV viral loads before vaccination are associated with reduced anti‐spike total antibody response in SARS‐CoV‐2 mRNA BNT162b2 vaccinated KT patients. The association between TTV viral load and vaccine response may be an added‐value in the optimization of vaccination regimens in KT. [ABSTRACT FROM AUTHOR]

Studies on the composition, richness and diversity of plant species in tropical communities are essential for understanding relevant ecological processes and for developing appropriate conservation policies. Considering that areas subject to direct impacts due to dam breach may in the long‐term present changes in species composition and in soil parameters, we evaluated the composition of the flora, described the current vegetation profile, and evaluated whether differences in species composition was influenced by soil variables of three areas along the Gualaxo River, in Minas Gerais State, Brazil. In addition, we identified important plant species through occurrence and phytosociological parameters for ecological restoration projects in the affected region, serving as reference areas. We sampled plant species with DBH ≥ 5 cm (diameter at breast height – measured 1.30 m above ground level) in 77 plots distributed in three riparian forest areas. We calculated phytosociological parameters and related them to edaphic factors. A total of 1579 individual plants belonging to 53 botanical families and 227 species were sampled in the three areas. The Fabaceae family was the most representative with 46 species. Species composition and diversity among the sampled areas was similar and was associated with edaphic factors. Furthermore, some species (e.g. Xylopia sericea, Cupania emarginata and Ocotea pulchalla) showed an important relation with soil variables. Some species of the genera (e.g. Byrsonima, Xylopia, Ocotea and Croton) and families (e.g. Fabaceae and Myrtaceae) found here, can be important species in the restauration process for the local and regional maintenance of floristic identity in the Rio Doce river.

The visual properties of the background occupied by organisms are a key aspect of visual camouflage. Changes in background coloration by fires may mediate the differential survival of prey against visually oriented predators and modify the prey camouflage strategy. This phenomenon may be common in environments where the fire is a continuous modulator of the community, such as Neotropical savannas. In this study, we investigated whether arthropods match burned and unburned trunks in coloration in order to camouflage relative to the visual system of potential bird predators. We also investigated in which type of the trunk the black and brown morphotypes of Ronderosia bergii (Orthoptera) preferentially occupy and whether the morphotypes present colour matching in the burned and unburned trunks. We recorded the arthropod community on backgrounds against which they had low contrast relative to other available backgrounds. We found that specimens of R. bergii preferentially occupy burned backgrounds. In addition, we also found that black morphotypes of R. bergii showed lower contrasts on burned trunks to the achromatic channel, while browner morphotypes showed lower contrasts on unburned backgrounds in the chromatic channel. We propose three explanations operating behind the observed pattern of the studied community: differential predation; background selection; and animal colour change. [ABSTRACT FROM AUTHOR]

PREDATION ,PREDATORY animals ,CATERPILLARS - Abstract
Although numerous studies about camouflage have been conducted in the last few decades, there is still a significant gap in our knowledge about the magnitude of protective value of different camouflage strategies in prey detection and survival. Furthermore, the functional significance of several camouflage strategies remains controversial. Here we carried out a comprehensive meta-analysis including comparisons of different camouflage strategies as well as predator and prey types, considering two response variables: mean predator search time (ST) (63 studies) and predator attack rate (AR) of camouflaged prey (28 studies). Overall, camouflage increased the predator ST by 62.56% and decreased the AR of prey by 27.34%. Masquerade was the camouflage strategy that most increased predator ST (295.43%). Background matching and disruptive coloration did not differ from each other. Motion camouflage did not increase ST but decreases AR on prey. We found no evidence that eyespot increases ST and decreases AR by predators. The different types of predators did not differ from each other, but caterpillars were the type of prey that most influenced the magnitude of camouflage's effect. We highlight the potential evolutionary mechanisms that led camouflage to be a highly effective anti-predatory adaptation, as well as potential discrepancies or redundancies among strategies, predator and prey types.

CALVES ,CATTLE ,ZEBUS ,OVUM ,OVARIAN follicle ,MILK yield - Abstract
Simple Summary: Brazil has the largest cattle commercial herd in the world, mostly of the Nelore breed (Bos taurus indicus), and it is one of the largest in vitro bovine embryo producers. However, Nelore cows experience puberty later than taurine breeds (Bos taurus taurus), which can lead to a delay in genetic improvement. Therefore, including calves as oocyte donors for in vitro embryo production programs could be an attractive step for reducing the interval between generations, accelerating the herd's genetic gains, and contributing to the sustainability of milk and meat production systems. Nevertheless, calves' oocytes are reported as less competent in generating embryos and establishing pregnancies than those collected from adult females. In addition, most studies have been carried out on taurines. Thus, this study's goal was to search for a better understanding of prepubertal Nelore females' reproductive development, related to the performance of their oocytes in terms of in vitro production of embryos. This can provide support for making decisions on the use of this animal category as an oocyte donor and prospects for hormonal protocols or changes in the culture media for in vitro embryo production. The purpose of this study was to characterize the reproductive physiology, oocyte competence, and chromatin compaction in Nelore calves in the early-prepubertal period (EPP) and the intermediate-prepubertal period (IPP). Calves aged 2–5 (EPP) and 8–11 months old (IPP) were assigned to Trial 1 (morpho-physiological–endocrine evaluations, n = 8) or Trial 2 (oocyte donors, n = 8) vs. the respective control groups of cows (n = 8, each). All morphological endpoints, except the antral follicle count, increased from the EPP to the IPP. The EPP LH-FSH plasma concentrations were similar to cows, whereas LH was lower and FSH was higher in the IPP than in cows.. Cows produced more Grade I (12.9% vs. 4.1% and 1.7%) and fewer Grade III COC (30.1% vs. 44.5% and 49.0%) than the EPP and IPP calves, respectively. The IPP calves' oocyte diameter was similar to those from cows but greater than those from EPP females (124.8 ± 8.5 and 126.0 ± 7.5 μm vs. 121.3 ± 7.5 μm, respectively). The expression of the chromatin compaction-related gene HDAC3 was downregulated in calves. The proportion of the blastocyst rate to the controls was lower in EPP than in IPP calves (43.7% vs. 78.7%, respectively). Progressive oocyte competence was found during the prepubertal period, which can help to decide whether to recover oocytes from calves. [ABSTRACT FROM AUTHOR]

- Abstract
Periodontitis is greatly related to worse perceived oral health-related quality of life (OHRQoL), yet this association has never been explored using radiographically screened periodontal bone loss. Here we have radiographically screened patients for periodontitis via a validated method and assessed its association with measures of OHRQoL. From a total of 10,267 participants (6,112 females and 4,155 males), self-reported general health questionnaire, body mass index, self-reported oral health behaviours, panoramic x-rays and the oral health impact profile (OHIP-14) were gathered. Radiographically screened periodontitis was measured through a radiographic-based periodontal bone loss (R-PBL) approach. We compared the respective variables according to the R-PBL status and explored using multiple logistic regression adjusted for the significant variables. Overall, patients with periodontitis shown significantly different sociodemographic, health measures and oral hygiene characteristics. All domains of the OHIP-14 were significantly worsened in the periodontitis group, and further confirmed through adjusted logistic regression (p<0.001). Active smoking, number of missing teeth, sex and age were the most impactful variables in this relationship. Our results demonstrate the existence of a link between radiographically screened periodontitis and OHRQoL, mostly upheld by active smoking, number of missing teeth, sex and age.

Codling moth (CM), Cydia pomonella L., is an important pest of apples worldwide. CM resistance to insecticides is a serious problem in apple production. For effective management and control, monitoring of resistant CM populations is absolutely necessary. Therefore, in this study, we investigated whether it is possible to find a reliable pattern of differences in CM populations related to the type of apple control method. The genetic results showed low estimated value of the pairwise fixation index, F
ST = 0.021, which indicates a lack of genetic differentiation and structuring between the genotyped populations. Different approaches were used to analyze the genetic structure of codling moth populations: Bayesian-based model of population structure (STRUCTURE), principal component analysis (PCA), and discriminant analysis of principal components (DAPC). STRUCTURE grouped the CM genotypes into two distinct clusters, and the results of PCA were consistent with this. The DAPC revealed three distinct groups. However, the results showed that population genetic differentiation between organic and integrated orchards was not significant. To confirm the genetic results, the forewing morphology of the same CM individuals was examined using geometric morphometric techniques based on the venation patterns of 18 landmarks. The geometric results showed higher sensitivity and separated three distinct groups. Geometric morphometrics was shown to be a more sensitive method to detect variability in genotypes due to pest control management. This study shows the possibility of using a novel method for a strategic integrated pest management (IPM) program for CM that is lacking in Europe. [ABSTRACT FROM AUTHOR]- Published

- Abstract
The aims of this study were to assess All-Patient Refined Diagnosis-Related Groups’ (APR-DRG) Severity of Illness (SOI) and Risk of Mortality (ROM) as predictors of in-hospital mortality, comparing with Charlson Comorbidity Index (CCI) and Elixhauser Comorbidity Index (ECI) scores. We performed a retrospective observational study using mainland Portuguese public hospitalizations of adult patients from 2011 to 2016. Model discrimination (C-statistic/ area under the curve) and goodness-of-fit (R-squared) were calculated. Our results comprised 4,176,142 hospitalizations with 5.9% in-hospital deaths. Compared to the CCI and ECI models, the model considering SOI, age and sex showed a statistically significantly higher discrimination in 49.6% (132 out of 266) of APR-DRGs, while in the model with ROM that happened in 33.5% of APR-DRGs. Between these two models, SOI was the best performer for nearly 20% of APR-DRGs. Some particular APR-DRGs have showed good discrimination (e.g. related to burns, viral meningitis or specific transplants). In conclusion, SOI or ROM, combined with age and sex, perform better than more widely used comorbidity indices. Despite ROM being the only score specifically designed for in-hospital mortality prediction, SOI performed better. These findings can be helpful for hospital or organizational models benchmarking or epidemiological analysis. [ABSTRACT FROM AUTHOR]
