AbstractThe Magellanic sub‐Antarctic Forest is home to the world's southernmost avian community and is the only Southern Hemisphere analogue to Northern Hemisphere temperate forests at this latitude. This region is considered among the few remaining pristine areas of the world, and shifts in environmental conditions are predominantly driven by climate variability. Thus, understanding climate‐driven demographic processes is critical for addressing conservation issues in this system under future climate change scenarios. Here, we describe annual survival patterns and their association with climate variables using a 20‐year mark–recapture data set of five forest bird species in the Cape Horn Biosphere Reserve. We develop a multispecies hierarchical survival model to jointly explore age‐dependent survival probabilities at the community and species levels in a group of five forest passerines. At the community level, we assess the association of migratory behavior and body size with survival, and at the species level, we investigate the influence of local and regional climatic variables on temporal variations of survival. We found a positive effect of precipitation and a negative effect of El Niño Southern Oscillation on juvenile survival in the white‐crested Elaenia and a consistent but uncertain negative effect of temperature on survival in juveniles and 80% of adults. We found only a weak association of climate variables with survival across species in the community and no temporal trends in survival for any of the species in either age class, highlighting apparent stability in these high austral latitude forests. Finally, our findings provide an important resource of survival probabilities, a necessary input for assessing potential impacts of global climate change in this unique region of the world.

AbstractUnderstanding population dynamics, movements, and fishing mortality is critical to establish effective shark conservation measures across international boundaries in the ocean. There are few survival and dispersal estimates of juveniles of oceanic shark species in the North Atlantic despite it being one of the most fished regions in the world. Here we provide estimates of dispersal, survival, and proportion of fishing mortality in the North Atlantic for two threatened oceanic sharks: the blue shark (Prionace glauca) and the shortfin mako shark (Isurus oxyrinchus). Our results are based on multi‐event models applied to tag‐recovery data of 700 blue sharks and 132 shortfin makos tagged over a decade. A total of 60 blue sharks (8.57% of tagged) and 30 makos (22.73%) were recovered by the longline fishery between 2009 and 2017. Tag‐reporting rate (percentage of returned information when a tagged shark was caught) was estimated to be high (0.794 ± 0.232 SE). Mean annual survival, as predicted from the models, was higher for blue shark (0.835 ± 0.040 SE) than for shortfin mako (0.618 ± 0.189 SE). Models predicted that fishing caused more than a half of total mortality in the study area for both species (0.576 ± 0.209), and more than a third of tagged individuals dispersed from the study area permanently (0.359 ± 0.073). Our findings, focused mainly on juveniles from oceanic areas, contribute to a better understanding of shark population dynamics in the North Atlantic and highlight the need for further conservation measures for both blue shark and shortfin mako, such as implementing efficient bycatch mitigation measures and static/dynamic time–area closures in the open ocean.
Predatory walls may impair climate warming‐associated population expansion

Published: June 2023

AbstractClimate change has a profound impact on species distribution and abundance globally, as well as local diversity, which affects ecosystem functioning. In particular, changes in population distribution and abundance may lead to changes in trophic interactions. Although species can often shift their spatial distribution when suitable habitats are available, it has been suggested that predator presence can be a constraint on climate‐related distribution shifts. We test this using two well‐studied and data‐rich marine environments. Focusing on a pair of sympatric fishes, Atlantic haddock Melanogrammus aeglefinus and cod Gadus morhua, we study the effect of the presence and abundance of the latter on the former distribution. We found that the distribution of cod and increased abundance may limit the expansion of haddock to new areas and could consequently buffer ecosystem changes due to climate change. Though marine species may track the rate and direction of climate shifts, our results demonstrate that the presence of predators may limit their expansion to thermally suitable habitats. By integrating climatic and ecological data at scales that can resolve predator–prey relationships, this analysis demonstrates the usefulness of considering trophic interactions to gain a more comprehensive understanding and to mitigate the effects of climate change on species distributions.

Published: June 2023

AbstractThe application of advanced oxidation processes (AOPs) based on sulfate radicals for degrading persistent organic pollutants faces challenges due to the inefficient activation of peroxydisulfate (PDS) oxidant. Herein, a composite CoFe2O4/MoS2‐xOy (CFM) catalyst consisting of CoFe2O4 nanoparticles uniformly dispersed on the nanosheets of oxygen‐incorporated MoS2 (MoS2‐xOy) with flower‐like morphology are fabricated through a facile two‐step hydrothermal method, which results in the enhanced activation of PDS and a highly efficient degradation of phenolic pollutants. The oxygen‐doping in MoS2‐xOy leads to unsaturated sulfur and active sites on the surface of MoS2 for accelerating the rate limiting step of FeIII/FeII reduction cycle in PDS‐CFM reaction. Aiming at the refractory organic pollutants in actual coking wastewater, CFM co‐catalyst is introduced into a hydrogel made up of polyvinyl alcohol (PVA) and coal‐tar pitch oxides (PO) to construct a multifunctional CFM@PO/PVA hydrogel. Upon hybrid CFM@PO/PVA, the coupling of the enhanced AOP with solar‐driven interfacial vapor generation (SIVG) technology contributes to the degradation efficiency, the removal rate of phenol in solution and the total organic carbon in coking wastewater can reach 98 % and 91 %, respectively. The integration of heterogeneous AOPs with SIVG system provides a feasible strategy for the eco‐friendly efficient purification of industrial wastewater.

Published: June 2023

AbstractWe present a comprehensive host‐guest study of four substituted and unsubstituted [10]cycloparaphenylenes with the fullerenes C60 and C70. Within this study, the influence on the complexation behavior was investigated experimentally and computationally. Due to the increased steric demand the substitution on the nanohoop results in an energetic penalty, which could be partially compensated by additional substituent‐fullerene interactions. These attractive interactions are intensified in the C70 complexes and with an increased degree of substitution. For the computational investigation conformer ensembles were taken into account, providing reliable structures with Boltzmann weighted energies. An analysis of the noncovalent interactions elucidated the origin of the enhanced substituent‐C70 interaction. The ellipsoid fullerene C70 can be considered as a π‐extended version of C60, which is able to increase the attractive van der Waals interactions within these supramolecular complexes.
Contextualizing the current state of research on the use of machine learning for student performance prediction: A systematic literature review

Published: June 2023

AbstractToday, educational institutions produce large amounts of data with the deployment of learning management systems. These large datasets provide an untapped potential to support and enhance decision‐making and operations. In recent times, machine learning (ML) has been applied to develop models utilizing this “big” data to assist in decision‐making. This study presents a systematic literature review into the application of ML to predict student performance. A total of 162 research articles from January 2010 to October 2022 were critically reviewed and analyzed by applying Kitchenham's systematic literature review approach. Our analysis categorized the literature predicting students' academic performance into two categories: (i) predicting student performance in assessments, courses or programs, and identifying students at‐risk of failing their course/program (129 studies); and (ii) predicting student dropout or retention in a course or program (33 studies). Classification is the most commonly used approach for predicting student performance (138 studies), followed by regression (25 studies) and clustering (9 studies). Supervised learning methods are used more often than semi‐supervised learning. Five most popular ML algorithms include the Decision Tree, Random Forest, Naïve Bayes, Artificial Neural Network, and Support Vector Machine. Historical records of students' grades and class performance, academic related data from learning management systems, and students' demographics are the most common features used for predicting students' performance. The most common methods used for feature selection are Information Gain‐based selection algorithms, Correlation‐based feature selection, and Gain Ratio. The general platforms/tools/libraries used in the studies include WEKA, Python, R, Rapid Miner, and MATLAB. We also investigated possible actions considered in the literature to help at‐risk students. We only found very few studies that deployed remedial actions and evaluated their impact on students' performance. In conclusion, ML has shown great potential in the prediction of student performance, but also has many areas of further research.
Evaluation of adsorptive performance of Adhatoda vasica on lead by batch process
Authors: Syed Farooq Ahmed , Battula Vijayasaradhi 
Published: June 2023

AbstractPowdered leaves of Adhatoda vasica are used to investigate the adsorptive capacity of lead in a batch system. The conventional heavy metal removal approaches like ion exchange, membranes, precipitation, adsorption, etc. are proven, but are costly and harmful to the environment. The proposed approach explores the possibility of a biosorption technique for removing lead from aqueous solutions using A. vasica leaf powder. It is a low‐cost, non‐conventional, readily, and abundantly available plant‐based material. The equilibrium biosorption data was analyzed using the Langmuir, Freundlich, and Temkin isotherm models, with the Freundlich model providing the best description of the equilibrium dynamics. The kinetic analysis shows pseudo‐second order to be the best fit, revealing the spontaneous and endothermic nature of adsorption. The maximum biosorption capacity for lead is 5.903 mg g−1 indicating the adsorptive capacity of A. vasica under favorable process conditions.

Published: June 2023

Abstract
We used yellow perch (Perca flavescens) captured at four sites differing in legacy industrial pollution in the Lake St. Clair–Detroit River system to evaluate the lingering sublethal effects of industrial pollution. We emphasized bioindicators of direct (toxicity) and indirect (chronic stress, impoverished food web) effects on somatic and organ-specific growth (brain, gut, liver, heart ventricle, gonad). Our results show that higher sediment levels of industrial contaminants at the most downstream Detroit River site (Trenton Channel) are associated with increased perch liver detoxification activity and liver size, reduced brain size, and reduced scale cortisol content. Trenton Channel also displayed food web disruption, where adult perch occupied lower trophic positions than forage fish. Somatic growth and relative gut size were lower in perch sampled at the reference site in Lake St. Clair (Mitchell's Bay), possibly because of increased competition for resources. Models used to determine the factors contributing to site differences in organ growth suggest that the lingering effects of industrial pollution are best explained by trophic disruption. Thus, bioindicators of fish trophic ecology may prove advantageous to assess the health of aquatic ecosystems. Environ Toxicol Chem 2023;42:2158–2170. © 2023 The Authors.

Abstract

Published: June 2023

AbstractThe risk of congenital heart defects (CHDs) may be influenced by maternal genes, fetal genes, and their interactions. Existing methods commonly test the effects of maternal and fetal variants one‐at‐a‐time and may have reduced statistical power to detect genetic variants with low minor allele frequencies. In this article, we propose a gene‐based association test of interactions for maternal–fetal genotypes (GATI‐MFG) using a case‐mother and control‐mother design. GATI‐MFG can integrate the effects of multiple variants within a gene or genomic region and evaluate the joint effect of maternal and fetal genotypes while allowing for their interactions. In simulation studies, GATI‐MFG had improved statistical power over alternative methods, such as the single‐variant test and functional data analysis (FDA) under various disease scenarios. We further applied GATI‐MFG to a two‐phase genome‐wide association study of CHDs for the testing of both common variants and rare variants using 947 CHD case mother–infant pairs and 1306 control mother–infant pairs from the National Birth Defects Prevention Study (NBDPS). After Bonferroni adjustment for 23,035 genes, two genes on chromosome 17, TMEM107 (p = 1.64e−06) and CTC1 (p = 2.0e−06), were identified for significant association with CHD in common variants analysis. Gene TMEM107 regulates ciliogenesis and ciliary protein composition and was found to be associated with heterotaxy. Gene CTC1 plays an essential role in protecting telomeres from degradation, which was suggested to be associated with cardiogenesis. Overall, GATI‐MFG outperformed the single‐variant test and FDA in the simulations, and the results of application to NBDPS samples are consistent with existing literature supporting the association of TMEM107 and CTC1 with CHDs.

Published: June 2023

AbstractBackground and AimsThe use of lasers has been increasing in various surgical procedures. Its specific characteristics have conquered the scalpel used to a major extent in certain surgical procedures. This scoping review aimed to assess the empirical evidence that exists on the quality of life (QoL) of dental patients treated with laser surgery.MethodsThis scoping review was conducted in accordance with the Arksey and O'Malley's guidelines for scoping reviews. Four electronic databases (PubMed, SCOPUS, CINAHL Complete, and APA PsycInfo) were systematically searched through a stepwise approach, informed by the PEO (Population [P], Exposure [E], and Outcome [O]) framework, to retrieve literatures relevant to the review question. After a two‐staged and Rayyan‐aided screening process, only those literatures meeting the inclusion criteria were included into the review. From the included literatures, data were extracted, collated, summarized, and presented.ResultsThe literature search retrieved 246 articles, of which only 10 articles were selected according to the inclusion criteria. Five of the studies were from the United Kingdom and three were from Italy. Study designs were either cohort (60%) or randomized controlled trials (40%). A vast variation was observed in the study populations. The used QoL instruments were mostly disease/condition‐specific and oral cancer was the most reported disease in the included articles. The patients who underwent laser surgery had better QoL on the 7th day postoperatively, although it was not significant in later days.ConclusionDepending on the indication, Laser is a safe surgical approach that could enhance the clinical outcome as well as the QoL of dental patients. Laser effects were more significant in the domain of postoperative pain. Due to the limited number of studies evaluated in this review, further longitudinal studies are needed to corroborate the findings of this review.

AbstractBody area network has attracted extensive attention for its applications in athletics, medical, diagnosis, and rehabilitation training in the next generation personalized health care solutions. Here, a contact‐separation direct current triboelectric nanogenerators (CSDC‐TENGs) based self‐powered wireless body area network (SWBAN) is reported that enables multi‐joint movements monitoring for human motion. The CSDC‐TENG is designed as a flexible active sensor with an internal contact switch, and the flexible substrate makes the TENG‐sensor stick onto skin easily. Due to the internal switch, the CSDC‐TENG could generate a DC current, a large instantaneous output voltage exceeds 700 V, and an instantaneous power can reach 1.076 W, which is more than 23 000 times higher than that of the traditional contact‐separation mode TENG in same size and materials without the switch. By coupling with flexible coil, the fixed high‐frequency radio signals can be modulated and emitted clearly ranging from 6 to 16 MHz, which can be wirelessly received and demodulated through a reader. Moreover, the SWBAN is demonstrated in a real time monitoring system for joints motion. This work has realized the wearable TENG for self‐powered wireless real‐time monitoring of body movements driven by low‐frequency human daily activities, which may promote a tremendous development of intelligent healthcare, wireless sensing system and body area network.image

Published: June 2023

AbstractDiabetic wounds nowadays have become a major health challenge with the changes of the disease spectrum. Mitochondria are closely associated with stubborn nonhealing diabetic wounds for their vital role in energy metabolism, redox homeostasis, and signal transduction. There is significant mitochondrial dysfunction and oxidative stress in diabetic wounds. However, the contribution of mitochondrial dysfunction in oxidative stress induced nonhealing diabetic wound is still not fully understood. In this review, we will briefly summarize the current knowledge of the reported signaling pathways and therapeutic strategies involved in mitochondrial dysfunction in diabetic wounds. The findings provide further understanding of strategies that focus on mitochondria in diabetic wound treatment.

AbstractMethotrexate (MTX) is a chemotherapeutic agent widely used to treat a variety of tumors. Nonetheless, MTX‐induced hippocampal neurotoxicity is a well‐defined dose‐limiting adverse effect that limits clinical utility. Proinflammatory cytokine production and oxidative stress are possible mechanisms for MTX‐induced neurotoxicity. Buspirone (BSP), a partial agonist of the 5‐HT1a receptor (5‐HT1aR), has emerged as an anxiolytic drug. BSP has been shown to possess antioxidant and anti‐inflammatory effects. The current study investigated BSP's potential anti‐inflammatory and antioxidant effects in attenuating MTX‐induced hippocampal toxicity. Rats received either BSP (1.5 mg/kg) orally for 10 days and MTX (20 mg/kg) i.p. on Day 5. BSP administration markedly protected hippocampal neurons from drastic degenerated neuronal changes induced by MTX. BSP significantly attenuated oxidative injury by downregulating Kelch‐like ECH‐associated protein 1 expression while potently elevating hippocampal Nrf2, heme oxygenase‐1, and peroxisome proliferator‐activated receptor expression. BSP dampened inflammation by reducing NO2−, tumor necrosis factor‐alpha, IL‐6, and interleukin 1 beta levels mediated by downregulating NF‐κB and neuronal nitric oxides synthase expression. Moreover, BSP potently counteracted hippocampal pyroptosis by downregulating NLRP3, ASC, and cleaved‐caspase‐1 proteins. Therefore, BSP may represent a promising approach to attenuate neurotoxicity in patients receiving MTX.
