Accelerating across the landscape: the energetic costs of natal dispersal in a large herbivore.

1.Dispersal is a key mechanism enabling species to adjust their geographic range to rapid global change. However, dispersal is costly and environmental modifications are likely to modify the cost-benefit balance of individual dispersal decisions, for example, by decreasing functional connectivity. 2.Dispersal costs occur during departure, transience and settlement, and are levied in terms of energy, risk, time and lost opportunity, potentially influencing individual fitness. However, to the best of our knowledge, no study has yet quantified the energetic costs of dispersal across the dispersal period by comparing dispersing and philopatric individuals in the wild. 3.Here, we employed animal-born bio-loggers on a relatively large sample (N = 105) of juvenile roe deer to estimate energy expenditure indexed using the vector of dynamic body acceleration (VeDBA) and mobility (distance travelled) in an intensively monitored population in the south west of France. We predicted that energy expenditure would be higher in dispersers compared to philopatric individuals. We expected costs to be i/ particularly high during transience, ii/ especially high in the more fragmented areas of the landscape, and iii/ concentrated during the night to avoid disturbance caused by human activity. 4.There were no differences in energy expenditure between dispersers and philopatric individuals during the pre-dispersal phase. However, dispersers expended around 22% more energy and travelled around 63% further per day than philopatric individuals during transience. Differences in energy expenditure were much less pronounced during the settlement phase. The costs of transience were almost uniquely confined to the dawn period, when dispersers spent 23% more energy and travelled 112% further than philopatric individuals. Finally, the energetic costs of transience per unit time and the total distance travelled to locate a suitable settlement range were higher in areas of high road density. 5.Our results provide strong support for the hypothesis that natal dispersal is energetically costly and indicate that transience is the most costly part of the process, particularly in fragmented landscapes. Further work is required to link dispersal costs with fitness components so as to understand the likely outcome of further environmental modifications on the evolution of dispersal behaviour.

Functional Brain Hyperactivations Are Linked to an Electrophysiological Measure of Slow Interhemispheric Transfer Time after Pediatric Moderate/Severe Traumatic Brain Injury

Increased task-related blood oxygen level dependent (BOLD) activation is commonly observed in functional magnetic resonance imaging (fMRI) studies of moderate/severe traumatic brain injury (msTBI), but the functional relevance of these hyperactivations and how they are linked to more direct measures of neuronal function remain largely unknown. Here, we investigated how working memory load (WML)-dependent BOLD activation was related to an electrophysiological measure of interhemispheric transfer time (IHTT) in a sample of 18 msTBI patients and 26 demographically matched controls from the UCLA RAPBI (Recovery after Pediatric Brain Injury) study. In the context of highly similar fMRI task performance, a subgroup of TBI patients with slow IHTT had greater BOLD activation with higher WML than both healthy control children and a subgroup of msTBI patients with normal IHTT. Slower IHTT treated as a continuous variable was also associated with BOLD hyperactivation in the full TBI sample and in controls. Higher WML-dependent BOLD activation was related to better performance on a clinical cognitive performance index, an association that was more pronounced within the patient group with slow IHTT. Our previous work has shown that a subgroup of children with slow IHTT after pediatric msTBI has increased risk for poor white matter organization, long-term neurodegeneration, and poor cognitive outcome. BOLD hyperactivations after msTBI may reflect neuronal compensatory processes supporting higher-order capacity demanding cognitive functions in the context of inefficient neuronal transfer of information. The link between BOLD hyperactivations and slow IHTT adds to the multi-modal validation of this electrophysiological measure as a promising biomarker.
The Mitochondrial Antioxidant SS-31 Modulates Oxidative Stress, Endoplasmic Reticulum Stress, and Autophagy in Type 2 Diabetes

Mitochondrial dysfunction has been shown to play a central role in the pathophysiology of type 2 diabetes (T2D), and mitochondria-targeted agents such as SS-31 are emerging as a promising strategy for its treatment. We aimed to study the effects of SS-31 on leukocytes from T2D patients by evaluating oxidative stress, endoplasmic reticulum (ER) stress and autophagy. Sixty-one T2D patients and 53 controls were included. Anthropometric and analytical measurements were performed. We also assessed reactive oxygen species (ROS) production, calcium content, the expression of ER stress markers GRP78, CHOP, P-eIF2α, and autophagy-related proteins Beclin1, LC3 II/I, and p62 in leukocytes from T2D and control subjects treated or not with SS-31. Furthermore, we have evaluated the action of SS-31 on leukocyte-endothelium interactions. T2D patients exhibited elevated ROS concentration, calcium levels and presence of ER markers (GRP78 and CHOP gene expression, and GRP78 and P-eIF2α protein expression), all of which were reduced by SS-31 treatment. SS-31 also led to a drop in BECN1 gene expression, and Beclin1 and LC3 II/I protein expression in T2D patients. In contrast, the T2D group displayed reduced p62 protein levels that were restored by SS-31. SS-20 (with non-antioxidant activity) did not change any analyzed parameter. In addition, SS-31 decreased rolling flux and leukocyte adhesion, and increased rolling velocity in T2D patients. Our findings suggest that SS-31 exerts potentially beneficial effects on leukocytes of T2D patients modulating oxidative stress and autophagy, and ameliorating ER stress.
Adding Acoustical to Visual Movement Patterns to Retest Whether Imitation Is Goal- or Pattern-Directed

This study compared two different motor skill modeling presentations (with and without goal display) in visual and audio-visual conditions for learning a complex skill (basketball jump shot) to evaluate the importance of (a) audio information and (b) goal observation in motor performance kinematics. Specifically, we sought to understand whether the simultaneous presentation of auditory and visual patterns could usefully direct the learner’s attention from goal to pattern stimuli. I selected 40 students (Mage = 20.47 years) who had no prior experience with the basketball jump shot or free throw and randomly assigned them into four groups: Pattern/Visual, Pattern/Audio-Visual, Pattern-Goal/Visual, and Pattern-Goal/Audio-Visual. Participants in the pattern-only groups watched only the skilled motor pattern, while those in the pattern-goal groups watched both the pattern and its outcome. Participants in the visual-only groups simply watched the visual pattern, while those in audio-visual groups saw and heard the pattern; we sonified the angular velocity of the skilled performer’s elbow joint. Participants then performed in two conditions with and without balls. On all dependent variables, the participants’ performance following the audio-visual presentations was better than when following the visual-only presentations. In addition, the participants’ performance in pattern-only groups was better than in pattern-goal groups, but this improved pattern-only performance was far less extensive in the audio-visual than in the visual-only group. In sum, complex motor skill imitation was enhanced by an audio pattern of elbow angular velocity in support of generalist theories of imitation learning.
Apigenin from Croton betulaster Müll restores the immune profile of microglia against glioma cells

The flavonoid apigenin, extracted from the Brazilian plant Croton betulaster Müll. has demonstrated the ability to inhibit proliferation, induce differentiation, and modify the inflammatory profile of glioma cells. The aim of the present study was to evaluate the effect of apigenin on chemotaxis and regulation of inflammatory cytokines of microglia cells and these impacts on glioma cell growth. In cultures of isolated rat microglia, it was observed that apigenin induced changes in Iba1‐positive cells to an ameboid phenotype, associated to an increase in the expression of the activated M1 profile marker OX‐42 and iNOS and a reduction in the expression of the M2 profile marker CD206. Besides, apigenin modulated the tumor necrosis factor and IL‐10 release by microglia. Treatment of C6 glioma cells with conditioned medium of microglia treated with apigenin‐induced reduction of tumor migration and viability, associated with significant reduction in IL‐6 levels. On the other hand, treatment of C6 cells with apigenin‐induced microglia chemotaxis to glioma in vitro. Moreover, apigenin treatment of microglia/C6 co‐cultures induced preferentially reduction in the viability of C6 cells and increased microglia‐activated phenotype, associated with a change in the balance of TNF/IL‐10 levels. Together, these results demonstrated that the flavonoid apigenin restores the immune profile of microglia against glioma cells.
CDK7 inhibition suppresses Castration-Resistant Prostate Cancer through MED1 inactivation.

Metastatic castration-resistant prostate cancer (CRPC) is a fatal disease, primarily resulting from the transcriptional addiction driven by Androgen Receptor (AR). First-line CRPC treatments typically target AR-signaling, but are rapidly bypassed, resulting in only a modest survival benefit with the anti-androgens. Therapeutic approaches that more effectively block the AR-transcriptional axis are urgently needed. Here, we investigated the molecular mechanism underlying the association between the transcriptional co-activator MED1 and AR as a vulnerability in AR-driven CRPC. MED1 undergoes CDK7-dependent phosphorylation at T1457 and physically engages AR at super-enhancer sites, and is essential for AR-mediated transcription. Additionally, a CDK7 specific inhibitor THZ1 blunts AR-dependent neoplastic growth by blocking AR/MED1 co-recruitment genome-wide, as well as reverses the hyper-phosphorylated MED1 associated enzalutamide resistant phenotype. In vivo, THZ1 induces tumor regression of AR amplified castration-resistant human prostate cancer in xenograft mouse model. Together, we demonstrate that CDK7 inhibition selectively targets MED1-mediated, AR-dependent oncogenic transcriptional amplification, thus representing a potential new approach for the treatment of CRPC.
Wish to Die: Suicide and Its Link to Euthanasia

This article analyzes suicidal behavior and how its inherent processes of death ideation can overlap with those seeking euthanasia. We present a literature review of three main events in suicide (suicidal ideation, suicide attempt, and suicide) in different populations and evaluate implications for health-care practice and risk assessment taking into account the context of euthanasia. We ponder upon the motives behind suicide and its link with wish to die requests to hasten death. We discuss the possibility of the reversal of a wish to die as well as a potential process of differentiating between individuals who would maintain their wish and benefit from termination of life and others who would later change their minds.
A Brief Review about the Role of Nanomaterials, Mineral-Organic Nanoparticles, and Extra-Bone Calcification in Promoting Carcinogenesis and Tumor Progression

People come in contact with a huge number of nanoparticles (NPs) throughout their lives, which can be of both natural and anthropogenic origin and are capable of entering the body through swallowing, skin penetration, or inhalation. In connection with the expanding use of nanomaterials in various industrial processes, the question of whether there is a need to study the potentially adverse effects of NPs on human health becomes increasingly important. Despite the fact that the nature and the extent of damage caused depends on the chemical and the physical characteristics of individual NPs, there are also general mechanisms related to their toxicity. These mechanisms include the ability of NPs to translocate to various organs through endocytosis, as well as their ability to stimulate the production of reactive oxygen species (ROS), leading to oxidative stress, inflammation, genotoxicity, metabolic changes, and potentially carcinogenesis. In this review, we discuss the main characteristics of NPs and the effects they cause at both cellular and tissue levels. We also focus on possible mechanisms that underlie the relationship of NPs with carcinogenesis. We briefly summarize the main concepts related to the role of endogenous mineral organic NPs in the development of various human diseases and their participation in extra-bone calcification. Considering data from both our studies and those published in scientific literature, we propose the revision of some ideas concerning extra-bone calcification, since it may be one of the factors associated with the initiation of the mechanisms of immunological tolerance.
Substrate-induced electronic localization in monolayer MoS2 measured via terahertz spectroscopy.

We study terahertz (THz) optoelectronic properties of monolayer (ML) MoS2 placed on different substrates such as SiO2/Si, sapphire, and quartz. Through the measurements of THz Fourier transform spectroscopy (2.5-6.5 THz) and THz time-domain spectroscopy (TDS, 0.2-1.2 THz), we find that the real part of optical conductivity increases for ML MoS2 on SiO2/Si and sapphire substrates and decreases for it on quartz with increasing radiation frequency. It is shown that the complex optical conductivity for ML MoS2, obtained from THz TDS measurements, can fit very well to the Drude-Smith formula. Thus, the dependence of optical conductivity of ML MoS2 on different substrates can be understood via a mechanism of electronic localization, and the electron density, relaxation time, and localization factor of the sample can be determined optically. Furthermore, we examine the influence of temperature on these key parameters in ML MoS2 on different substrates. The results obtained from this Letter indicate that THz spectroscopy is a very powerful tool in studying and characterizing ML MoS2-based electronic systems, especially in examining the electronic localization effect which cannot be directly measured in conventional electrical transport experiment. This Letter is relevant to an in-depth understanding of the optoelectronic properties of ML MoS2 and of the proximity effect induced by different substrates.
Efficacy of adaptive e-learning for health professionals and students: a systematic review and meta-analysis

Objective Although adaptive e-learning environments (AEEs) can provide personalised instruction to health professional and students, their efficacy remains unclear. Therefore, this review aimed to identify, appraise and synthesise the evidence regarding the efficacy of AEEs in improving knowledge, skills and clinical behaviour in health professionals and students. Design Systematic review and meta-analysis. Data sources CINAHL, EMBASE, ERIC, PsycINFO, PubMed and Web of Science from the first year of records to February 2019. Eligibility criteria Controlled studies that evaluated the effect of an AEE on knowledge, skills or clinical behaviour in health professionals or students. Screening, data extraction and synthesis Two authors screened studies, extracted data, assessed risk of bias and coded quality of evidence independently. AEEs were reviewed with regard to their topic, theoretical framework and adaptivity process. Studies were included in the meta-analysis if they had a non-adaptive e-learning environment control group and had no missing data. Effect sizes (ES) were pooled using a random effects model. Results From a pool of 10 569 articles, we included 21 eligible studies enrolling 3684 health professionals and students. Clinical topics were mostly related to diagnostic testing, theoretical frameworks were varied and the adaptivity process was characterised by five subdomains: method, goals, timing, factors and types. The pooled ES was 0.70 for knowledge (95% CI −0.08 to 1.49; p.08) and 1.19 for skills (95% CI 0.59 to 1.79; p<0.00001). Risk of bias was generally high. Heterogeneity was large in all analyses. Conclusions AEEs appear particularly effective in improving skills in health professionals and students. The adaptivity process within AEEs may be more beneficial for learning skills rather than factual knowledge, which generates less cognitive load. Future research should report more clearly on the design and adaptivity process of AEEs, and target higher-level outcomes, such as clinical behaviour. PROSPERO registration number CRD42017065585
Evaluation of a high-protein DDGS product in broiler chickens: performance, nitrogen-corrected apparent metabolisable energy, and standardised ileal amino acid digestibility

ABSTRACT 1. New production processes and additional uses for corn co-products have increased the availability of distiller’s dried grains with solubles (DDGS) with varying energy and amino acid digestibility, for use in poultry feed. The objective of this study was to determine the performance, N-corrected metabolisable energy (AMEn), and amino acid (AA) digestibility of a 34% CP (as fed) high-protein DDGS (HP-DDGS) included in poultry diets for Cobb 500 broiler chickens. 2. A total of 832 Cobb 500 broilers were randomly assigned to four dietary treatments containing 5% conventional DDGS (CV-DDGS) as a control or 10%, 15% and 20% HP-DDGS and fed for 42 d. After the performance trial, 240 birds from the original 832 were selected for a concurrent AMEn and AA digestibility experiment consisting of two AMEn diets and two AA diets. 3. Birds fed diets containing 15% and 20% HP DDGS gained less weight than birds fed the CV-DDGS (P < 0.05) but did not differ in feed intake (FI), and therefore had a less efficient FCR than the control (P < 0.05). The AMEn of HP-DDGS was determined to be 11.4 MJ/kg. The standardised ileal amino acid digestibility (SIAAD) of the essential amino acids Lys and Met were determined to be 80.9% and 88.6%, respectively. 4. HP-DDGS can be included in broiler diets up to 10% without any negative impact on performance or requiring supplemental Lys and Arg. The results from the AA digestibility study indicated that HP-DDGS could be a good source of digestible Lys.
Effectiveness of a Combined Intervention on Psychological and Physical Capacities of Frail Older Adults: A Cluster Randomized Controlled Trial

Background: Older adults experience physical and psychological declines affecting independency. Adapted and structured combined interventions composed of cognitive stimulation and physical exercise contribute to comorbidities’ reduction. Methods: Multicenter single-blinded two-arm cluster randomized controlled trial conducted to assess effectiveness of a combined intervention (CI), composed of a cognitive stimulation program (CSP) and a physical exercise program (PEP), on psychological and physical capacities of frail older adults as to on their activities of daily living. Were recruited 50 subjects from two elderly end-user organizations. Of these, 44 (65.9% females, mean age of 80.5 ± 8.47 years) were considered eligible, being randomly allocated in experimental (EG) or control group (CG). Data collected at baseline and post-intervention. EG received CI three times a week during 12 weeks. CG received standard care. Non-parametric measures were considered. Results: At baseline, groups were equivalent for study outcomes. The comparison of pre- and post-intervention data revealed that subjects receiving CI reduced depressive symptomatology and risk of fall based on gait and balance, and improved gait speed. Simultaneously, in the CG a significant decline on activities of daily living was observed. Significant results were found among biomechanical parameters of gait (BPG). EG’ effect size revealed to be small (0.2 ≤ r < 0.5). CG’ effect size was also small; but for activities of daily living there was an evident decrease. Conclusion: The CI is effective on managing older adults’ psychological and physical capacities.
Phytoaccumulation of Zn, Pb, and Cd in Conocarpus lancifolius irrigated with wastewater: does physiological response influence heavy metal uptake?

Abstract Conocarpus lancifolius is a fast-growing and drought tolerant tree species with phytoremediation potential in arid environments. The present study was conducted to evaluate the phytoaccumulation potential under wastewater treatment. The experiment was performed in a greenhouse where 3-month-old seedlings were irrigated with industrial wastewater and growth, biomass and physiological parameters were measured. Concentrations of zinc (Zn), lead (Pb), and cadmium (Cd) in leaves, shoots, and roots along with translocation and tolerance index were also determined. The results showed that under wastewater treatment total biomass increased from 24.2 to 31.5 g, net CO2 assimilation rate increased from 9.93 to 13.3 μmol m−2 s−1, and water use efficiency increased from 1.7 to 2.42. Similarly, heavy metals (Zn, Pb, and Cd) accumulation in stem, leaves, and roots increased significantly under wastewater treatment where the highest concentration of Zn, Pb and Cd was found in roots followed by leaves and stem, respectively. Tolerance index was found >1, and translocation factor of all heavy metals was found >1. The study revealed that phytoaccumulation potential of C. lancifolius was mainly driven by improved net CO2 assimilation rate and water use efficiency.
Outcomes of subsequent pregnancies in patients following treatment of cesarean scar pregnancy with high intensity focused ultrasound followed by ultrasound-guided dilation and curettage

Abstract Objective: To evaluate the outcomes of subsequent pregnancies in patients with a history of cesarean scar pregnancy (CSP) treated with high intensity focused ultrasound (HIFU) followed by ultrasound-guided dilation and curettage (USg-D&C). Methods: A retrospective analysis was performed on data collected from 154 patients with CSP who were treated by HIFU followed by USg-D&C in Suining Central Hospital between January 2015 and January 2018. Among them, 28 patients wanted to conceive following treatment. Baseline characteristics, treatment results, intraoperative hemorrhages during USg-D&C, post-curettage serum beta human chorionic gonadotropin (β-hCG) levels and vaginal bleeding were investigated. Subsequent pregnancy outcomes, including intervals between pregnancy and treatment of CSP, complications during pregnancy, and outcomes of newborns were evaluated. Results: All patients with CSP were successfully treated by HIFU combined with USg-D&C. Of the 28 CSP patients who intended to conceive after the treatment, 23 patients (82.14%) successfully conceived. The average interval between conception and HIFU treatment was 18.38 ± 10.04 months. Eighteen patients (78.26%) had an intrauterine pregnancy, in which 12 had delivery by cesarean section, 1 had an ongoing pregnancy, and 5 had an abortion in the first trimester. Among the other 5 women, 3 had tubal ectopic pregnancy and 2 had recurrent CSP. These five patients underwent laparoscopy within the first trimester. Conclusion: HIFU followed by USg-D&C is an effective and safe treatment for patients with CSP who wish to conceive. Prospective multi-center studies with larger sample sizes and longer follow-up periods are needed to compare this treatment with others.
