The Impact of the Educational Counselor in Promoting Student Achievement Level in Government Schools at Irbid Governorate From School Principal Perspective

One of the purposes and objectives of this research is to identify and assess the impact of the effectiveness of a school counselor on the academic success of students-an effectiveness that is manifested through the provision of academic, psychosocial, and vocational support to students, as well as through the facilitation of the interactions among students, teachers, and parents. In order to accomplish this study, the opinions of 180 public school principals were sought, and they were selected randomly to allow unbiased and generalizable interpretations of the principals in the governorate of Irbid to be the research population. A survey method was employed for data collection, and it consisted of a survey specifically designed for this research study, which contained several paragraphs related to the primary areas of the school counselor's role, as listed above. The responses collected were analyzed by establishing the means and the standard deviations. This research aimed to understand better the significant contribution that school counselors can offer in enhancing the educational process and academic progress within public schools in Irbid. It also confirmed that the multi-faceted support that they provide is essential. Results. In the study evaluating the role of the educational counselor within the scope of the public schools of Irbid, the results of which have been collected from school principals, the work provides a positive evaluation of the perceived influence of the counselors in terms of students' academic achievement across four primary dimensions: academic support that had a mean of 4.2 and a standard deviation of 0.8; psychological support with a mean of 4.0 and standard deviation of 0.9; vocational guidance with a mean of 3.8 and a standard deviation of 0.7; and interaction with parents and teachers with a mean of 4.1 and a standard deviation of 0.6. Such results reveal a high appreciation of the importance of the role of the educational counselor in improving the educational environment and the comprehensive support for the student as the role of the counselor has been exposed as a practical element in supporting the student academically and psychologically, guiding the student professionally, and in addition promoting effective communication between the school and the family.

Brain-wide circuitry underlying altered auditory habituation in zebrafish models of autism.

Auditory processing is widely understood to occur differently in autism, though the patterns of brain activity underlying these differences are not well understood. The diversity of autism also means brain-wide networks may change in various ways to produce similar behavioral outputs. We used larval zebrafish to investigate auditory habituation in four genetic lines relevant to autism: fmr1, mecp2, scn1lab and cntnap2. In free-swimming behavioral tests, we found each line had a unique profile of auditory hypersensitivity and/or delayed habituation. Combining the optical transparency of larval zebrafish with genetically encoded calcium indicators and light-sheet microscopy, we then observed brain-wide activity at cellular resolution during auditory habituation. As with behavior, each line showed unique alterations in brain-wide spontaneous activity, auditory processing, and adaptation in response to repetitive acoustic stimuli. We also observed commonalities in activity across our genetic lines that indicate shared circuit changes underlying certain aspects of their behavioral phenotypes. These were predominantly in regions involved in sensory integration and sensorimotor gating rather than primary auditory areas. Overlapping phenotypes include differences in the activity and functional connectivity of the telencephalon, thalamus, dopaminergic regions, and the locus coeruleus, and excitatory/inhibitory imbalance in the cerebellum. Unique phenotypes include loss of activity in the habenula in scn1lab, increased activity in auditory regions in fmr1, and differences in network activity over time in mecp2 and cntnap2. Comparing these distinct but overlapping brain-wide auditory networks furthers our understanding of how diverse genetic factors can produce similar behavioral effects through a range of circuit- and network-scale mechanisms.

Synergistic effects of climate and land use change on khulan (Equus hemionus hemionus) habitat in China

Climate and land use change are the primary drivers causing the reduction of habitat range for many species worldwide, especially wide-ranging and large-bodied ungulates. For instance, khulan (Equus hemionus hemionus), a flagship species inhabiting desert regions of Asia, exhibits heightened vulnerability to habitat loss and fragmentation due to their extensive habitat requirements. We simulated suitable khulan habitats in China across 20 scenarios, including the past (1980–2000), current (2001–2022), and future (2050 s and 2070 s) climate and land use change scenarios. For each scenario, we identified the suitable habitat area and evaluated the effectiveness of protected areas (PAs). Our findings revealed a decline in khulan habitat area from 133,006 km2 in the past to 60,141 km2 at present. Future scenarios indicate further reductions in potential khulan habitat, with more negative impacts resulting from climate change than land use change. Northern Xinjiang is expected to persist as a primary area of both in-situ and ex-situ refugia for khulan in future scenarios. Although suitable habitat within existing PAs is smaller than that outside, the rates of habitat loss and fragmentation outside the PAs surpass those inside PAs. These findings emphasize the importance of effective management strategies for PAs as crucial goals for ongoing conservation efforts for the khulan. Our models suggest that future suitable habitat for khulan will be situated along the international border between China and Mongolia, adjacent to protected areas in Mongolia utilized by khulan. Enhancing connectivity between these habitats could significantly contribute to improving both the climate and genetic resilience of khulan populations.

Spatial evolution and influencing factors of water-town settlements in Southern China: evidence from 942 villages in Zhongshan City

ABSTRACT Zhongshan, a city characterized by its profound historical heritage and distinctive rural civilization, has been consistently influenced by traditional agricultural practices throughout its history. This research conducts an in-depth exploration of Zhongshan’s unique rural spaces, systematically examining the evolutionary trends and determinants of Zhongshan’s water-town settlements across different historical epochs through the application of multidimensional spatial analysis techniques. The results indicate that these settlements exhibited cohesive spatial distribution characteristics across five historical periods. Notably, there was a significant clustering effect during the Ming and Qing dynasties, while Before the Qing dynasty, the spatial distribution of the settlements presented a pattern with multiple core areas coexisting. After the Qing dynasty, the spatial layout of these principal core areas stabilized and gradually diffused to surrounding areas, forming a balanced and continuous distribution pattern. Throughout the study period, the spatial pattern of the water-town settlements exhibited characteristics of five primary core areas and several secondary core areas. Concurrently, the centroid of the water-town settlements consistently shifted southeastward. When examining the intensity of influence on spatial evolution, the study found that socio-economic (q = 0.345) and accessibility factors (q = 0.356) exert a greater impact on the spatial distribution of rural settlements than do natural environmental factors (q = 0.136). However, the interaction between natural environmental factors and socio-economic and accessibility factors provides greater explanatory power than the interactions within natural factors alone. This suggests that in a specific socio-economic context, the impact of the natural environment on water-town settlements is enhanced. Furthermore, multivariate linear regression analysis demonstrates that the rural population, regional economic status, proximity to urban centers, and the distribution of water bodies positively influence the spatial evolution of water-town settlements.

Exploring the environmental, economic, and social implications of metaverse adoption in business and management

Recently, Metaverse has received increasing attention from both the business and academic worlds. However, its actual use in business and management is still confusing and limited. This study aims to provide a comprehensive overview of the environmental, economic, and social implications of the adoption of this technology within organizations. In addition, enabling technologies to Metaverse and business contexts in which the platform can be applied are identified. First, this study applies a systematic literature review (SLR) to investigate the use of Metaverse in business and management. Secondly, a content and cluster analysis were applied to the final sample of 656 articles to identify the Metaverse's primary research areas and future research directions. The results reveal that Metaverse has mainly social and economic implications such as enhancing collaboration, increasing accessibility, facilitating training, and encouraging productivity and profitability for companies. The major concerns for its implementation are privacy, security, user health, inclusiveness in access, implementation costs, and lack of regulation. Moreover, the application of content and cluster analysis techniques intercepted eight primary research areas defined as user experience, optimization, research method, educational change, business opportunities, security systems, enabling technologies, and healthcare. The article provides valuable insights to support management decision-making when considering the adoption of this technology in specific business contexts. To the best of the authors' knowledge, this is one of the first SLRs on Metaverse in the business and management field that classifies the opportunities, barriers, complementary technologies, and business functions and processes in which the platform can potentially be applied.

Multimodal and Repeated Localization of Primary Hand Motor Function to the Lateral Postcentral Gyrus in a Case of Frontal Motor Area Brain Metastasis

BACKGROUND AND IMPORTANCE: The human motor homunculus is a well-known topographical map of the functional-anatomical relationships of the precentral gyrus. Within this homunculus, the primary hand motor area is considered one of the least plastic functional-anatomical relationships. Only a few cases in the literature describe relocation of functional hand representation away from the classical anatomical location. These cases have been reported in the context of children, primary gliomas, or arteriovenous malformations. CLINICAL PRESENTATION: Here, we describe a unique case where the area of lowest hand motor stimulation threshold (ie, hand motor representation) was found in the postcentral gyrus in an older adult with a metastasis in the premotor area of the brain. This localization was based on intraoperative cortical stimulation–evoked motor potentials and confirmed with electrophysiological phase reversal and MRI-based neuronavigation. This mapping was repeated and consistent 2 months later during a reoperation for recurrence. In addition, the remapped anatomical location was found in an area that was active during finger tapping on preoperative functional MRI. CONCLUSION: These findings suggest that neuroplastic remapping of hand motor cortex to the postcentral gyrus can occur in brain metastases even in adults. This has implications for planning tumor resections and interventional neurorehabilitation strategies, and it suggests that the motor homunculus may have more plastic potential in adulthood than previously recognized.

Identification of Key Performance Metrics for Different Ultrasonic Surgical Devices

Abstract Ultrasonic surgical devices utilize high-frequency sound waves to perform surgical tasks, including cutting, fragmenting, emulsifying, and sealing tissues. Their multifunctional capabilities have facilitated their broad application across various surgical disciplines, such as general surgery, neurosurgery, and orthopedic surgery. While the current international standard, IEC 61847:1998 “Ultrasonics - Surgical Systems - Measurement and Declaration of the Basic Output Characteristics”, outlines a set of fundamental output characteristics for these devices, the diverse applications and performance requirements of each device necessitate the identification of key performance metrics. In this study, we delve into the applicability of these basic output characteristics for different ultrasonic surgical devices. Through comprehensive experimental evaluations on biological tissues, we assessed the influence of specific parameters, namely drive frequency, excursion amplitude, power output, duty cycle, and primary sound output area, on the cutting efficiency and coagulation results of three distinct ultrasonic surgical devices. Our results highlight the paramount parameters that govern the primary functions of these devices. This research offers invaluable insights for device manufacturers and evaluators, guiding them in prioritizing and emphasizing crucial parameters during the design, manufacturing, and evaluation phases of ultrasonic surgical devices.

Bibliometric analysis of skeletal muscle ischemia/reperfusion (I/R) research from 1986 to 2022

IntroductionTissue damage due to ischemia and reperfusion is a critical medical problem worldwide. Studies in this field have made remarkable advances in understanding the pathogenesis of ischemia/reperfusion (I/R) injury and its treatment with new and known drugs. However, no bibliometric analysis exists in this area of research. MethodsResearch articles and reviews related to skeletal muscle I/R from 1986 to 2022 were retrieved from the Web of Science Core Collection. Bibliometric analysis was performed using Microsoft Excel 2019, VOSviewer (version 1.6.19), Bibliometrix (R-Tool for R-Studio), and CiteSpace (version 6.1.R5). ResultsA total of 3682 research articles and reviews from 2846 institutions in 83 countries were considered in this study. Most studies were conducted in the USA. Hobson RW (UMDNJ-New Jersey Medical School) had the highest publication, and Korthuis RJ (Louisiana State University) had the highest co-citations. Our analysis showed that, though the Journal of Surgical Research was most favored, the Journal of Biological Chemistry had the highest number of co-citations. The pathophysiology, interventions, and molecular mechanisms of skeletal muscle I/R injury emerged as the primary research areas, with “apoptosis,” “signaling pathway,” and “oxidative stress” as the main keywords of research hotspots. ConclusionsThis study provides a thorough overview of research trends and focal points in skeletal muscle I/R injury by applying bibliometric and visualization techniques. The insights gained from our findings offer a profound understanding of the evolving landscape of skeletal muscle I/R injury research, thereby functioning as a valuable reference and roadmap for future investigations.

Heavy Metal Accumulation in Oysters from an Aquaculture Area in the Luoyangjiang River Estuary.

Oysters are a group of economically important bivalves in China, with estuaries serving as one of their primary cultivation areas. However, heavy metal pollution in these estuarine environments poses a potential threat to aquaculture by leading to the accumulation of heavy metals in farmed oysters, which could impact their safety and marketability. This study was conducted in the aquaculture area of the Luoyangjiang River estuary, where eight sampling sites were selected. Water, sediment, and oysters categorized by shell length were collected from each site. The concentrations of heavy metals (Ag, As, Cd, Cr, Cu, Ni, Pb, and Zn) were determined in both the environmental samples and oyster tissues. Additionally, multiplex species-specific PCR was used to identify oyster species. The results showed significant variations in dissolved-phase and suspended particulate matter (SPM) metal concentrations across different sampling sites, while sediment metal concentrations were more consistent but similar to those in SPM. The large oysters were comprised of 50% Magallana angulata and 50% Magallana gigas, while small oysters were identified as Magallana sikamea. The Cd, Cu, Pb, and Zn levels in both size groups of oysters exceeded data from previous studies, indicating contamination in the estuary. The observed differences in heavy metal concentrations between large and small oysters primarily reflect species-specific variability in metal accumulation, which may also be influenced by factors such as growth and exposure duration. Furthermore, the lack of significant correlation between metal concentrations in environmental media and oysters suggests that oysters may be exposed to multiple sources of metal contamination.

Estimating primary substation boundaries and the value of mapping Great Britain's electrical network infrastructure

Localised data aggregation in many countries including Great Britain (GB) is typically performed at a geographical level with polygon boundaries that have a robust and trusted governance system in place. This means there is confidence in a process to create a set of polygons that have unique identifiers coupled to geographical areas, and the ability to have these updated through a defined code of practice. Examples found across many countries are in the delivery of post, such as post codes and zip codes, and of the definition of census areas and municipal boundaries. The confidence in these boundaries allows different data to be aggregated by third parties, which itself provides greater amounts of data over comparable geographical areas to enhance wider analysis and decision making. As helpful as these polygons are for certain types of analyses, they are not specifically defined for energy systems analysis. Here we combine publicly available datasets published from the six regional electricity Distribution Network Operators of GB to produce a new geospatial dataset with 4436 unique polygons defining the areas served by electrical primary substations. An example demonstrating the value of these polygons is given to link these polygons with postcode level open government datasets on domestic energy consumption (2015–2020) from the Department of Energy Security and Net Zero (DESNZ). The resulting new data reflects energy statistics aggregated to the geographical areas served by each primary electrical substation across Great Britain. The significant value of the generated data is demonstrated by the quantification of the domestic annual heating demand presently met by natural gas across different primary substation areas which varies from an average of 5100 kWh to 28,900 kWh per property. This highlights how the rate of electrical capacity expansion will have to differ by geography under an electrified heating scenario. Therefore, we believe there is a compelling argument for all countries to set up processes to create and update polygons that have a meaningful relationship to energy systems. This would allow more accurate energy systems analysis to be performed, ultimately leading to an accelerated or potentially lower cost transition to a net zero world.

New potentially invasive species in the flora of Croatia - Diospyros virginiana L. (common persimmon)

During field research conducted from 2022 to 2023 on the island of Koločep, near the city of Dubrovnik, the spontaneous emergence of the non-native species Diospyros virginiana L. (common persimmon) was observed outside its primary cultivation area. This ornamental plant is part of the park dendroflora. D. virginiana began appearing spontaneously on the eastern side of the road between the two main settlements of the island, Gornje Čelo and Donje Čelo. It has established itself in an agricultural habitat within an abandoned olive grove covering an area of about 2900 m2. The plot, no longer under cultivation, is predominantly covered with ruderal and weedy vegetation, featuring an herbaceous ground layer identified as Dauco majori-Foeniculetum vulgaris. In this area, D. virginiana attains an average height of 1 to 2 meters, enveloping and suppressing the remaining Olea europaea L. trees. The plant spreads vegetatively and possesses a robust root system extending laterally for several meters, completely covering the area. Additionally, it has grown into a dry stone wall structure along the road. According to the author's proposal, it was recently entered in the FCD as 2.1.1.3, a potentially invasive species, to provide a basis for future monitoring. Considering its invasive potential and the environmental damage it may cause, the authors suggest the eradication of the species from the area before it spreads to surrounding regions.

Leveraging AI and Machine Learning for Performance Optimization in Web Applications

The rapid evolution of web technologies has placed an unprecedented demand on web applications to deliver high performance, scalability, and responsiveness. In this context, Artificial Intelligence (AI) and Machine Learning (ML) have emerged as transformative tools that can significantly optimize the performance of web applications. This paper explores the integration of AI and ML techniques in enhancing various aspects of web application performance, including load balancing, caching, resource management, and user experience personalization. The deployment of AI-driven algorithms enables real-time monitoring and predictive analytics, allowing for proactive adjustments to prevent bottlenecks and ensure smooth operation under varying loads. One of the primary areas where AI and ML contribute is in load balancing. Traditional load balancing techniques often rely on static or rule-based methods, which may not adapt well to dynamic web environments. AI-powered load balancers, however, can learn from traffic patterns and predict surges in demand, enabling more efficient distribution of traffic across servers. This adaptive approach not only improves response times but also reduces the risk of server overloads, enhancing the overall reliability of web applications.

Massification of Higher Education in Türkiye and Its Challenges

In the last 20 years, the education system in Türkiye has witnessed massive growth and transformation from primary- and secondary education to higher education. Significant improvements have been made in enrollment rates at all levels of education, reaching a level comparable to OECD countries. In this context, this study focuses on the transformation and massification of higher education in Türkiye. The net enrollment ratio in higher education in Türkiye has increased from 10% to 46% during this period. Especially, the establishment of higher education institutions in all cities has contributed positively to women's access to higher education, and for the first time, the enrollment and graduation rates of women have surpassed those of men. The increase in the supply of higher education and easier access has raised the proportion of higher education graduates from under 20% to over 40% in the 25-34 age group during this period. At the same time, the average length of education for the population aged 15 and over is increasing every year. Additionally, this study identifies problem areas and proposes solutions to ensure the sustainability of the expansion in higher education during this period. The evaluation identifies insufficient face-to-face teaching capacity in the higher education system and attempts to compensate for this deficiency with distance education programs as the primary problem area. Especially since 2015, almost half of the students who have enrolled in higher education have been able to enroll in distance education programs. Therefore, increasing face-to-face teaching capacity in higher education and reducing the proportion of distance education in higher education stand out as challenging issues. The second problem area is highlighted as being related to the limitations in scientific knowledge production performance of higher education institutions and the number of doctoral graduates. Despite an increase in the number of doctoral graduates from all disciplines every year, sustaining the growth achieved during this period is highly inadequate. This problem not only negatively affects the capacity for scientific knowledge production but also creates significant challenges, especially in meeting the need for faculty members in newly established universities, thus adversely affecting the quality of higher education. The study also offers some recommendations for addressing these problems.

Beyond Barrels: Diverse Thalamocortical Projection Motifs in the Mouse Ventral Posterior Complex.

Thalamocortical pathways from the rodent ventral posterior (VP) thalamic complex to the somatosensory cerebral cortex areas are a key model in modern neuroscience. However, beyond the intensively studied projection from medial VP (VPM) to the primary somatosensory area (S1), the wiring of these pathways remains poorly characterized. We combined micropopulation tract-tracing and single-cell transfection experiments to map the pathways arising from different portions of the VP complex in male mice. We found that pathways originating from different VP regions show differences in area/lamina arborization pattern and axonal varicosity size. Neurons from the rostral VPM subnucleus innervate trigeminal S1 in point-to-point fashion. In contrast, a caudal VPM subnucleus innervates heavily and topographically second somatosensory area (S2), but not S1. Neurons in a third, intermediate VPM subnucleus innervate through branched axons both S1 and S2, with markedly different laminar patterns in each area. A small anterodorsal subnucleus selectively innervates dysgranular S1. The parvicellular VPM subnucleus selectively targets the insular cortex and adjacent portions of S1 and S2. Neurons in the rostral part of the lateral VP nucleus (VPL) innervate spinal S1, while caudal VPL neurons simultaneously target S1 and S2. Rostral and caudal VP nuclei show complementary patterns of calcium-binding protein expression. In addition to the cortex, neurons in caudal VP subnuclei target the sensorimotor striatum. Our finding of a massive projection from VP to S2 separate from the VP projections to S1 adds critical anatomical evidence to the notion that different somatosensory submodalities are processed in parallel in S1 and S2.

Addressing the Gap: A Pilot Study to Improve Graduate Student's Counseling Self-Efficacy Through Online Support Groups for Care Partners of People With Acquired Brain Injuries

Purpose: The purpose of this technical report is to (a) describe the development and pilot testing of a university training initiative for graduate students in speech-language pathology to conduct online support groups for care partners of individuals with acquired brain injuries and (b) share preliminary data on students' self-efficacy in their counseling skills as a result of training. Method: Four graduate students completed an intensive summer counseling training program consisting of two 90-min student orientations to counseling skills and two online support group sessions for care partners of people with acquired brain injuries. A mixed methods analysis of pilot data collected over the summer of 2023 was conducted. Students completed the modified Counselor Activity Self-Efficacy Scales for speech-language pathologists within 1 week of beginning their counseling training and within 1 week after their clinical training experience. Students also submitted a short reflection paper within 24 hr of their two support group sessions to discuss their overall performance within the session and assess their self-efficacy in their counseling skills. Results: Preliminary data evidenced significant pre- to posttraining gains in two primary counseling areas: (a) psychoeducation (i.e., students' ability to provide information to care partners) and (b) empathy when addressing care partners' concerns regarding their loved one's communication disorder. Students' reflection papers illustrated their sense of growth as clinicians and paralleled the findings from their questionnaires. Conclusions: Our preliminary results highlight the importance of providing counseling opportunities for student clinicians in speech-language pathology graduate programs. Our online clinical model offers an example for replicability across universities to foster self-efficacy in students' counseling skills as part of their graduate studies. “Key” ingredients are provided for replication when developing a student-led online support group program for care partners of individuals with acquired brain injuries.

Microbial-Derived Carotenoids and Their Health Benefits

Natural carotenoids (CARs) such as β-carotene, astaxanthin, lutein, norbixin, bixin, capsanthin, lycopene, β-Apo-8-carotenal, canthaxanthin, β-apo-8-carotenal-ester, and zeaxanthin are being explored for possible applications in feed, food, cosmeceuticals, and nutraceuticals. Three primary areas of carotenoid research are emerging: (1) encapsulations for improved chemical and physical properties; (2) natural source carotenoid manufacturing; and (3) preclinical, epidemiological, and clinical studies of carotenoids’ potential health benefits. The recent advancements in research on the chemistry and antioxidant activity, marketing strategies, dietary sources, bioavailability, and bioaccessibility, extraction, dietary consumption, encapsulating techniques, and health advantages of carotenoids are all extensively discussed in this review. Carotenoids are pigments found naturally in most fruits and vegetables, algae, plants, and photosynthetic bacteria. Carotenoids cannot be synthesized by humans and must be consumed in the form of food or supplements. There are several roles for carotenoids in human health. Although individual carotenoids may function in different ways, their main action is to act as antioxidants. There are validated techniques for separating and purifying carotenoids, yet, industrial production requires the development of economically viable techniques for larger-scale implementation. Carotenoids have been shown to boost cognitive performance and cardiovascular health, as well as help prevent some types of cancer. Despite evidence for carotenoids’ health benefits, major population-based supplementation trials have yielded conflicting outcomes for several carotenoids. This review includes recent developments in carotenoid metabolism and nutritional and health advantages. It also offers an outlook on future directions in these areas.

Amugulang virus, a novel hantavirus harboured by small rodents in Hulunbuir, China

ABSTRACT The Hulunbuir region, known for its diverse terrain and rich wildlife, is a hotspot for various natural epidemic diseases. Between 2021 and 2023, we collected 885 wild rodent samples from this area, representing three families, seven genera, and eleven species. Metagenomic analysis identified three complete nucleic acid sequences from the S, M, and L segments of the Hantaviridae family, which were closely related to the Khabarovsk virus. The nucleotide coding sequences for S, M, and L (1392 nt, 3465 nt, and 6491 nt, respectively) exhibited similarities of 82.34%, 81.68%, and 81.94% to known sequences, respectively, while protein-level analysis indicated higher similarities of 94.92%, 94.41%, and 95.87%, respectively. Phylogenetic analysis placed these sequences within the same clade as the Khabarovsk, Puumala, Muju, Hokkaido, Topografov, and Tatenalense viruses, all of which are known to cause febrile diseases in humans. Immunofluorescence detection of nucleic acid-positive rodent kidney samples using sera from patients with hemorrhagic fever and renal syndrome confirmed the presence of viral particles. Based on these findings, we propose that this virus represents a new member of the Hantaviridae family, tentatively named the Amugulang virus, after its primary distribution area.

Scoping review exploring the evidence base on Vitis vinifera toxicity in dogs after ingestion: Clinical effects, treatments and types of V. vinifera.

Treatment of Vitis vinifera fruit (VVF) ingestion can be challenging due to no clear toxic dose, signalment factors and variable clinical signs. Current treatment guidance is generalised: decontamination, aggressive fluid therapy, monitoring and/or treatment of renal dysfunction. The objective of this study was to conduct a scoping review of scientific evidence regarding the ingestion of VVF in dogs. Three primary areas were reviewed: VVF types ingested, clinical signs reported and treatments given. The inclusion criterion was any paper presenting data on clinical signs or treatments of dogs that had ingested VVF (unprocessed VVF only). The following databases were searched: CAB Abstracts, Medline, Embase and Scopus. No limits were placed on language or date. The review followed the Joanna Briggs Institute scoping review methodology. Twenty-four papers were identified. A wide range of VVF types were ingested, but the toxic dose was difficult to ascertain. The most commonly reported signs were gastrointestinal, renal, neurological and haematological. Treatment commonly consisted of fluid therapy, diuretics and antiemetics. This scoping review neither explored cases of processed VVF ingestion nor did it chart laboratory findings; therefore, potentially clinically significant findings in these areas may have been missed. VVF ingestion typically causes gastrointestinal/renal dysfunction, with no clear toxicity attributable to VVF type. Treatments varied according to the presence/absence of clinical signs, and the prognosis was varied. Further research on current treatment efficacy is warranted, permitting an evidence-based, risk-benefit approach to be adopted by clinicians.

Expansion of Naturally Grown Phyllostachys edulis (Carrière) J. Houzeau Forests into Diverse Habitats: Rates and Driving Factors

Moso bamboo (Phyllostachys edulis (Carrière) J. Houzeau), which is native to China, is considered to be an invasive species due to its powerful asexual reproductive capabilities that allow it to rapidly spread into neighboring ecosystems and replace existing plant communities. In the absence of human intervention, it remains poorly understood how indigenous moso bamboo forests naturally expand into surrounding areas over the long term, and whether these patterns vary with environmental changes. Using multi-year forest resource inventory data, we extracted moso bamboo patches that emerged from 2010 to 2020 and proposed a bamboo expansion index to calculate the average rate of patch expansion during this period. Using the first global 30 m land-cover dynamic monitoring product with a fine classification system, we assessed the expansion speeds of moso bamboo into various areas, particularly forests with different canopy closures and categories. Using parameter-optimized geographic detectors, we explored the significance of multi-factors in the expansion process. The results indicate that the average expansion rate of moso bamboo forests in China is 1.36 m/y, with evergreen broadleaved forests being the primary area for invasion. Moso bamboo expands faster into open forest types (0.15 < canopy closure < 0.4), shrublands, and grasslands. The importance of factors influencing the expansion rate is ranked as follows: temperature > chemical properties of soil > light > physical properties of soil > moisture > atmosphere > terrain. When considering interactions, the primary factors contributing to expansion rates include various climate factors and the combined effect of climate factors and soil factors. Our work underscores the importance of improving the quality and density of native vegetation, such as evergreen broadleaved forests. Effective management strategies, including systematic monitoring of environmental variables, as well as targeted interventions like bamboo removal and soil moisture control, are essential for mitigating the invasion of moso bamboo.
