AbstractRestoring ecological dynamics is a key objective of conservation translocations. Exemplarily, reconnecting the reintroduced alpine populations with native Pyrenean populations through re‐establishing locally extinct populations in between, in the Causses and the Pre‐Alps, is a major goal for the long‐term conservation of Bearded Vultures in Europe. Understanding Bearded Vultures' post‐release movements and foraging behavior is critical to understanding the settlement of newly restored populations and to supporting conservation measures. The telemetric monitoring of 43 translocated and wild‐born juveniles allowed us to investigate whether differences exist in post‐release movements and foraging behavior during the first year of life between reintroduced and native populations. Medium‐ and long‐distance exploration movements start during the spring following fledging for both translocated and wild‐born individuals. However, birds translocated in the most distant release site (Causses) exhibited greater exploration distances with no clear directional movement pattern, had smaller home ranges, and had a stronger preference for supplementary feeding stations than those from other populations. Although some birds translocated in the Pre‐Alps displayed similar behaviors, the pattern is not as strong as in the Causses, likely because of the proximity to the breeding populations reintroduced in the Alps or differences in the number and management of supplementary feeding stations. Preference for supplementary feeding stations (SFS) mostly occurred in the Pre‐Alps and the native populations, but was lower in the Causses. Seasonal variations in SFS preference were consistent among populations, with a peak in the first spring following fledging. Beyond documenting post‐release movements in Bearded Vultures, we suggest better accounting for the demographic consequences of behaviors to track conservation translocation effectiveness, at both local and regional scales.
Responses of C4 grasses to aridity reflect species‐specific strategies in a semiarid savanna
Authors: Havrilchak Nicole A. , West Jason B. 
Published: August 2024

AbstractThe C4 Poaceae are a diverse group in terms of both evolutionary lineage and biochemistry. There is a distinct pattern in the distribution of C4 grass groups with aridity; however, the mechanistic basis for this distribution is not well understood. Additionally, few studies have investigated the functional strategies of co‐occurring C4 grass species for dealing with aridity in their natural environments. We explored the coordination of leaf‐level gas exchange, water use, and morphology among five co‐occurring semiarid C4 grasses belonging to divergent clades, biochemical subtypes, and size classes at three sites along a natural aridity gradient. More specifically, we measured predawn and midday water potential, stomatal conductance, water use efficiency, and photosynthesis. Leaf tissue was also collected for the analysis of stable isotopes of carbon and oxygen as well as for measurement of specific leaf area (SLA) and leaf width. Species differences in responsiveness of stomata to changes in vapor pressure deficit (VPD) were also assessed. It was expected that NAD‐me species would maintain higher rates of photosynthesis, higher water use efficiency, and have more responsive stomata than other co‐occurring species based on observed biogeographic patterns and past greenhouse studies. We found that Aristidoideae and Chloridoideae NAD‐me‐type grasses had greater stomatal sensitivity to VPD, consistent with a more isohydric strategy. However, midgrasses had both greater apparent water access and water use efficiency, regardless of subtype or lineage. PCK‐type species had less responsive stomata and maintained lower levels of photosynthesis with increasing aridity. There were strong interspecific differences in δ13C, leaf width, and SLA; however, these were not significantly correlated with water use efficiency. C4 grasses in our study did not fit discretely into functional groups as defined by lineage, biochemistry, or size class. Interspecific differences, evolutionary legacy, and biochemical pathway are likely to interact to determine water use and photosynthetic strategies of these plants. Control of water loss via highly responsive stomata may form the basis for dominance of certain C4 grass groups in arid environments. These findings build on our understanding of contrasting strategies of C4 grasses for dealing with aridity in their natural environments.

Published: August 2024

AbstractDiabetes often induces bone loss and the dysregulation of gut microbiota (GM) is an important cause. Punicalagin (PU) was reported to regulate GM. Therefore, we hypothesized that PU could alleviate diabetes‐induced bone loss through GM and their metabolites. In this study, high‐fat diet‐induced diabetic mice showed bone erosion and poor biomechanical properties, while PU intake significantly improved the bone condition of diabetic mice. Further investigation revealed that the abundance of some beneficial bacteria, such as Akkermansia and Ruminiclostridium_9, was higher after PU intake and highly positively correlated with the concentrations of short‐chain fatty acids (SCFAs) and serum vitamin K2, respectively. In addition, these bacteria were associated with the levels of bone metabolism‐related markers such as procollagen type I N‐terminal propeptide (P1NP) and runt‐related transcription factor‐2 (Runx2). Mechanistically, PU, on the one hand, promotes the metabolism of SCFAs, thereby increasing the levels of bone synthesis markers and inhibiting the secretion of bone absorption markers. On the other hand, the higher level of vitamin K2 greatly accelerated bone mineralization and enhanced bone strength. This work provides a new perspective to explore the mechanism by which PU intervention alleviates diabetes‐induced bone loss by regulating the GM and their metabolic products.

Published: August 2024

AbstractThe combination of spin crossover (SCO) with chirality has caught increasing research interest owing to its potential applications in the fields of multifunctional magnetic molecular materials and devices. In this work, we synthesized a pair of homochiral Co(II) SCO complexes and their racemic complex by applying chiral Schiff base terimine ligands modified by naphthyl group. Single‐crystal X‐ray diffraction results showed that the chiral ligands retained chirality after coordination with Co(II) ion, giving rise to a pair of enantiomeric Co(II) complexes in the RR and SS configurations, respectively. The circular dichroism spectroscopy demonstrated the enantiomeric nature of the homochiral complexes. The enantiomers exhibited similar thermally induced SCO, while the racemate was trapped in the high spin state. The differences in SCO behavior between the homochiral and racemic complexes are attributed to different supramolecular interactions. This work provides a feasible approach to constructing new chiral SCO materials and offers perspectives in developing switchable nonlinear optical magnetic materials.

AbstractThe Rb0.94Mn0.94Co0.06[Fe(CN)6]0.98 material was designed to exhibit a 75 K wide thermal hysteresis around room temperature, associated with a bistability between the low temperature MnIIIFeII tetragonal phase and the high temperature MnIIFeIII cubic phase. We have recently shown that a single laser pulse can be used to drive, at room temperature, the photoinduced phase transition from the MnIIIFeII tetragonal phase to the MnIIFeIII cubic phase. By using a specific powder sample streaming technique, we could monitor by time‐resolved X‐ray diffraction how the ultrafast out‐of‐equilibrium dynamics, imposed by the structural relaxation around the local photoinduced charge transfer, changes with the fluence of the laser pulse. In this paper we present a detailed structural analysis of the crystalline reorganizations associated with the charge‐transfer in different regimes of photoexcitation. In the low excitation polaronic regime, the photoinduced charge transfer is local and accompanied by an anisotropic distortion of the Mn coordination sphere and of the tetragonal lattice. In the high excitation regime, a macroscopic and cooperative charge‐transfer phase transition occurs towards the cubic lattice, where the coordination around the Mn reaches octahedral symmetry.
Experimental study on the shear characteristics of frozen soil‐concrete interface under the constant normal stiffness

Published: August 2024

AbstractThe interaction between the structure and soil is a crucial factor in infrastructure stabilization in cold region engineering, both transversely and vertically. During interface deformation, the transverse action is reflected in the change of constraints, including normal stiffness, normal stress, and normal volume, while the vertical action is reflected in the change of shear properties. However, the study of different transverse constraints is not systematic, especially considering the normal stiffness and shear properties at different hydrothermal states. This study investigated the shear behavior of the interface between concrete and frozen soil under different normal stiffness, temperature, and water content using the interface direct shear test under temperature‐controlled conditions. The results show that with the increase in temperature and water content, the initial shear stiffness of the interface shear stress‐shear displacement curve gradually increases, and the interface shear strength gradually increases. Different normal stiffnesses have a small effect on the morphology of the interfacial shear stress‐shear displacement curve but significantly affect the peak shear strength. The peak shear strength increases significantly with the increase of normal stiffness, and this trend is more obvious with the decrease in temperature. The corresponding interfacial cohesion and friction angle also increases with the increase in normal stiffness.

Abstract
Understanding how sublethal impacts of toxicants affect population-relevant outcomes for organisms is challenging. We tested the hypotheses that the well-known sublethal impacts of methylmercury (MeHg) and a polychlorinated biphenyl (PCB126) would have meaningful impacts on cohort growth and survival in yellow perch (Perca flavescens) and Atlantic killifish (Fundulus heteroclitus) populations, that inclusion of model uncertainty is important for understanding the sublethal impacts of toxicants, and that a model organism (zebrafish Danio rerio) is an appropriate substitute for ecologically relevant species (yellow perch, killifish). Our simulations showed that MeHg did not have meaningful impacts on growth or survival in a simulated environment except to increase survival and growth in low mercury exposures in yellow perch and killifish. For PCB126, the high level of exposure resulted in lower survival for killifish only. Uncertainty analyses increased the variability and lowered average survival estimates across all species and toxicants, providing a more conservative estimate of risk. We demonstrate that using a model organism instead of the species of interest does not necessarily give the same results, suggesting that using zebrafish as a surrogate for yellow perch and killifish may not be appropriate for predicting contaminant impacts on larval cohort growth and survival in ecologically relevant species. Our analysis also reinforces the notion that uncertainty analyses are necessary in any modeling assessment of the impacts of toxicants on a population because it provides a more conservative, and arguably realistic, estimate of impact.

Published: August 2024

AbstractSocial media sentiment influences housing market trading and policy‐making in China. To explore the multiscale relationship between social media sentiment and house price index (HPI) and improve prediction performance, a sentiment‐based decomposition–ensemble approach is proposed for HPI forecasting. In this approach, five steps, that is, sentiment analysis for massive Weibo textual reviews about house prices, data decomposition for bivariate time series integrated by HPI and the sentiment index (SI), data smoothing for high‐frequency components, component reconstruction for all individual modes, and all components prediction and ensemble, are involved. For verification, the National‐level and two city‐level house price indices are used as the sample data. The empirical results illustrate that the proposed approach can achieve better performance than all considered benchmark models at multi‐step‐ahead prediction horizons, indicating that it can be used as an effective tool for HPI forecasting.

AbstractAlthough 7 T MRI research has contributed much to our understanding of multiple sclerosis (MS) pathology, most prior data has come from small, single‐center studies with varying methods. In order to truly know if such findings have widespread applicability, multicenter methods and studies are needed. To address this, members of the North American Imaging in MS (NAIMS) Cooperative worked together to create a multicenter collaborative study of 7 T MRI in MS. In this manuscript, we describe the methods we have developed for the purpose of pooling together a large, retrospective dataset of 7 T MRIs acquired in multiple MS studies at five institutions. To date, this group has contributed five‐hundred and twenty‐eight 7 T MRI scans from 350 individuals with MS to a common data repository, with plans to continue to increase this sample size in the coming years. We have developed unified methods for image processing for data harmonization and lesion identification/segmentation. We report here our initial observations on intersite differences in acquisition, which includes site/device differences in brain coverage and image quality. We also report on the development of our methods and training of image evaluators, which resulted in median Dice Similarity Coefficients for trained raters' annotation of cortical and deep gray matter lesions, paramagnetic rim lesions, and meningeal enhancement between 0.73 and 0.82 compared to final consensus masks. We expect this publication to act as a resource for other investigators aiming to combine multicenter 7 T MRI datasets for the study of MS, in addition to providing a methodological reference for all future analysis projects to stem from the development of this dataset.

Published: August 2024

AbstractObjectiveTo assess the predictive abilities of Doppler‐based resistive index and plasma biomarkers of endothelial cell activation in identifying persistent acute kidney injury (pAKI) among patients with septic shock.MethodPatients diagnosed with septic shock were categorized into none AKI (n = 25), transient AKI (tAKI, n = 47), and pAKI (n = 48) groups. Kidney function parameters (urine output, serum creatinine, and serum urea) were measured within the initial 24 h upon intensive care unit (ICU) admission. The Doppler‐based resistive index, and the plasma biomarkers [fractalkine, soluble E‐Selectin (sE‐Selectin), and soluble intercellular adhesion molecule‐1 (sICAM‐1)] were evaluated upon admission to the ICU.ResultsThe predictive capacity of Doppler‐based resistive index for distinguishing pAKI at day 3 from none AKI/tAKI in septic shock patients was moderate, with sensitivity of 47.92% and specificity of 76.39%. Fractalkine levels displayed significant differences across groups and exhibited a favorable predictive ability for pAKI at day 3 (AUC = 0.800), while sE‐Selectin and sICAM‐1 showed moderate predictive abilities (AUC = 0.636 and 0.634, respectively). Comparative analysis of predictive models demonstrated that incorporating kidney function parameters, Doppler‐based resistive index, and plasma biomarkers yielded the highest AUC of 0.903, followed closely by the model utilizing serum creatinine, urine output, and plasma fractalkine, with an AUC of 0.896.ConclusionIntegrating kidney function parameters, along with Doppler‐based resistive index and plasma biomarkers of endothelial cell activation, yielded the strongest predictive model for pAKI. Additionally, the combination of serum creatinine, urine output, and plasma fractalkine shows promise in risk assessment and management strategies for pAKI.

AbstractBackground and AimsDegenerative cervical myelopathy (DCM) is a debilitating condition characterized by compression of the cervical spinal cord, leading to neurological deficits. This study aimed to investigate the association between comorbidities like diabetes mellitus (DM) and obesity and quality of life (QOL) in preoperative patients with DCM, and to examine the distribution of pain and numbness.MethodsA cross‐sectional study with 86 preoperative patients with DCM was conducted. Patient‐reported outcome measures (PROMs) including Core Outcome Measure Index for the neck (COMI‐Neck), Neck Disability Index (NDI), EQ‐5D‐3L, SF‐12v2 assessed QOL, and baseline characteristics were collected. Patients were categorized by diabetic and obesity status, resulting in 17 with and 69 without DM, and 27 obese, 59 nonobese patients. In the statistical analysis, we compared PROMs and baseline characteristics, and conducted MANCOVA to investigate the association of DM and obesity with PROMs.ResultsThe study found no significant differences in preoperative QOL between patients with and without DM or obesity. Additionally, the results of MANCOVA indicated that neither DM nor obesity alone, nor their combination, had an association with the total scores of PROMs. In each group, the Symptom‐specific well‐being score on the COMI‐Neck was notably high, implying distressing current symptoms (median: 10). On the NDI, the median score for pain intensity, lifting, work, and recreation subitems was 3. Pain was predominantly reported in the neck and lower back, while numbness was more prevalent in the peripheral regions of the upper and lower limbs.ConclusionPreoperative QOL was not significantly affected by the presence of DM and/or obesity. DCM‐related symptoms may mask the associations with these comorbidities. Regardless of the preoperative condition, it is important to address the PROMs items that posed challenges before surgery.

Published: August 2024

AbstractBackground and AimsThe preference of beauty seekers for noninvasive, convenient, and long‐lasting effective facial cosmetic techniques with minimal downtime and recovery time is obvious nowadays. As a part of traditional Chinese medicine, acupuncture has great advantages in solving these problems. This study aims to assess the effectiveness of two distinct acupuncture techniques for facial rejuvenation in treating nasolabial folds (NFs) and marionette lines (MLs).MethodsOne hundred beauty seekers who have received facial acupuncture cosmetic treatment in hospitals between June 1, 2020, and December 31, 2022, were selected randomly and inquired. Among them, 50 beauty seekers (Group Ⅰ) have received a normal facial traditional Chinese medicine acupuncture therapy, by inserting the needles perpendicularly into the acupoints. Meanwhile, another 50 beauty seekers (Group Ⅱ) were treated by needle knives, which were inserted parallelly under the dermis and basically along the meridians of Chinese medicine linked by the acupoints. The records of pain evaluation and adverse events on cases, subjective satisfactions, and objective evaluations of efficacy were summarized and statistically analyzed.ResultsThe efficacy of Group Ⅱ is better than Group Ⅰ. The dermatologists' assessments for NF and ML show significant differences between Groups Ⅰ and Ⅱ after one course. The mean value of subjective satisfaction also obeys the rules above. Although Group Ⅱ exhibited the highest value of mean pain intensity, the adverse events were basically mild. Furthermore, Group Ⅱ showed higher willingness for additional treatments.ConclusionOnly in terms of the wrinkle depth of NF and ML, the method of acupuncturing parallelly under the dermis by needle knife is safe and more successful.
