Increasing corn cultivation exacerbated crop residue burning in Northeast China in 21st century

China's endeavors to mitigate recurrent crop residue burning (CRB) and improve air quality have yielded positive results owing to recent pollution prevention policies. Nonetheless, persistent challenges remain, particularly in the Northeast China (NEC), where low temperature complicates crop residue management. Here, we examined the effects of cropping pattern adjustment on variations of CRB patterns in NEC during 2001–2021, utilizing the Moderate-resolution Imaging Spectroradiometer (MODIS) burned area dataset, the Visible Infrared Imaging Radiometer Suite (VIIRS) active fire dataset, and the high-accuracy crop planting area maps. Our results revealed an overall upward trend of 805.96 km2/yr in NEC CRB from 2001 to 2021. The corn CRB area accounted for more than 50% of the total CRB area in each CRB-intensive year (2013–2021), and the increasing corn CRB generally aligns with the growing corn cultivation fields. A seasonal shift in CRB was found around 2017, with intensive CRB activities transitioning from both autumn and spring to primarily spring, particularly in the Songnen Plain and Sanjiang Plain. The changing trend of PM2.5 concentration aligned spatially with the shift. Moreover, the CRBs in spring of 2020 and 2021 were more severe than the major burning seasons in previous years, likely due to the disruptions during COVID-19 lockdowns. In certain years, the explanatory power of spring CRB on PM2.5 concentration was comparable to that of other natural factors, such as precipitation. This study underscores the critical need for sustained and region-specific strategies to tackle the challenges posed by CRBs.

The Amount and Pattern of Reciprocal Compensations Predict Performance Stability in a Visually Guided Finger Force Production Task.

Previous work suggests that synergistic activity among motor elements implicated in force production tasks underlies enhanced performance stability associated with visual feedback. A hallmark of synergistic activity is reciprocal compensation, that is, covariation in the states of motor elements that stabilizes critical performance variables. The present study examined if characteristics of reciprocal compensation are indicators of individuals' capacity to respond adaptively to variations in the resolution of visual feedback about criterion performance. Twenty healthy adults (19.25 ± 1.25years; 15 females and five males) pressed two sensors with their index fingers to produce a total target force equivalent to 20% of their maximal voluntary contraction under nine conditions that differed in the spatial resolution of real-time feedback about their performance. By combining within-trial uncontrolled manifold and sample entropy analyses, we quantified the amount and degree of irregularity (i.e.,non-repetitiveness) of reciprocal compensations over time. We found a U-shaped relationship between performance stability and gain. Importantly, this relationship was moderated by the degree of irregularity of reciprocal compensation. Lower irregularity in reciprocal compensation patterns was related to individuals' capacity to maintain (or minimize losses in) performance under changes in feedback resolution. Results invite future investigation into how interindividual variations in reciprocal compensation patterns relate to differences in control strategies supporting adaptive responses in complex, visually guided motor tasks.

Enhancing Arabidopsis thaliana ubiquitination site prediction through knowledge distillation and natural language processing

Protein ubiquitination is a critical post-translational modification (PTM) involved in diverse biological processes and plays a pivotal role in regulating physiological mechanisms and disease states. Despite various efforts to develop ubiquitination site prediction tools across species, these tools mainly rely on predefined sequence features and machine learning algorithms, with species-specific variations in ubiquitination patterns remaining poorly understood. This study introduces a novel approach for predicting Arabidopsis thaliana ubiquitination sites using a neural network model based on knowledge distillation and natural language processing (NLP) of protein sequences. Our framework employs a multi-species “Teacher model” to guide a more compact, species-specific “Student model”, with the “Teacher” generating pseudo-labels that enhance the “Student” learning and prediction robustness. Cross-validation results demonstrate that our model achieves superior performance, with an accuracy of 86.3 % and an area under the curve (AUC) of 0.926, while independent testing confirmed these results with an accuracy of 86.3 % and an AUC of 0.923. Comparative analysis with established predictors further highlights the model’s superiority, emphasizing the effectiveness of integrating knowledge distillation and NLP in ubiquitination prediction tasks. This study presents a promising and efficient approach for ubiquitination site prediction, offering valuable insights for researchers in related fields.

Microbiological profiles in periprosthetic joint infections after total knee arthroplasty: a comparative analysis of diabetic and non-diabetic patients.

The purpose of this study is to conduct a comparative analysis of the microbiological profiles in periprosthetic joint infections (PJIs) after total knee arthroplasty (TKA) between diabetic and non-diabetic patients. The study aims to address what are the variations in microbial colonization and infection patterns between diabetic and non-diabetic patients undergoing total knee arthroplasty. A retrospective analysis of 2,569 culture-positive cases of PJIs post-TKA was conducted, comparing outcomes between diabetic (n = 321) and non-diabetic (n = 2,248) patients. Demographic, clinical, and microbiological data were collected and analyzed using descriptive statistics, chi-squared tests, logistic regression, and other statistical tests. Diabetic patients exhibited distinct microbial colonization patterns, with a higher prevalence of pathogens such as Staphylococcus aureus (p = 0.033), Pseudomonas aeruginosa (p < 0.001), Streptococcus spp. (Streptococcus agalactiae and Streptococcus dysgalactiae; p = 0.010, 0.016 respectively), Candida spp. (p = 0.010), and Corynebacterium spp. (p = 0.024). Additionally, diabetic patients were at increased risk of polymicrobial infections. Comorbidities associated with diabetes, including chronic pulmonary disease, renal insufficiency, and peripheral artery disease, were significantly more prevalent in diabetic patients and further complicated PJI outcomes. This study underscores the importance of tailored perioperative antimicrobial strategies and vigilant infection control measures in diabetic patients undergoing TKA. Understanding the differential microbial profiles and associated comorbidities can inform targeted interventions to mitigate the risk of PJIs and improve outcomes in this high-risk population. Further research is warranted to elucidate the underlying mechanisms and optimize management strategies for diabetic patients undergoing TKA.

The opioid crisis has emerged as a significant public health concern globally, with India facing unique challenges in preventing and managing substance abuse. This systematic review aims to analyze the current state of the opioid crisis in India, evaluate existing prevention and management strategies, and propose evidence-based recommendations for addressing this complex issue. A comprehensive literature search was conducted across multiple databases, resulting in the inclusion of 30 studies meeting the predefined criteria. The review highlights the multifaceted nature of the opioid crisis in India, influenced by factors such as socioeconomic conditions, cultural norms, and healthcare accessibility. Key findings include the need for comprehensive prevention programs, improved access to evidence-based treatments, and integration of harm reduction strategies. The review also emphasizes the importance of addressing co-occurring mental health disorders and the potential of community-based interventions in managing substance abuse. Challenges identified include stigma, limited access to treatment, inadequate healthcare infrastructure, regulatory barriers, and lack of comprehensive policies. Recommendations for future directions include developing culturally appropriate prevention programs, assessing the long-term effectiveness of treatment modalities, exploring innovative approaches to reduce stigma, and investigating the role of technology in improving access to care. By implementing a multifaceted approach that considers the unique sociocultural context of India (including factors such as family structures, religious beliefs, economic disparities, and regional variations in drug use patterns), there is potential to significantly reduce the burden of opioid abuse and improve outcomes for affected individuals and communities.

Contrast-Enhanced Ultrasound of Mouse Models of Hindlimb Ischemia Reveals Persistent Perfusion Deficits and Distinctive Muscle Perfusion Patterns

ObjectiveMouse models of hindlimb ischemia (HLI) are used to study peripheral arterial disease and evaluate novel therapies. Contrast-enhanced ultrasound (CEUS) is a noninvasive perfusion measurement technique that is increasingly being employed in these models. The objective of this study was to evaluate two models of severe HLI by CEUS to characterize perfusion recovery and muscle perfusion patterns. MethodsMice undergoing double femoral artery ligation were measured by CEUS and laser Doppler perfusion imaging (LDPI) at baseline and 1–150 d postsurgery. A second group undergoing femoral artery ligation and excision was measured 1–28 d postsurgery. ResultsBy LDPI, both surgeries showed robust perfusion recovery by 14 d postsurgery. However, by CEUS only a ∼40% perfusion recovery plateau was reached in either group. These results are consistent with our previous work, employing a less severe single femoral artery ligation, that showed perfusion in the ischemic limb does not return to normal by 150 d postsurgery. Cluster analysis of muscle perfusion patterns indicated 3–5 different patterns at day 1 postsurgery. The double ligation model yielded significantly less variable perfusion patterns, suggesting that it can provide more reproducible results. ConclusionContrary to LDPI, perfusion as measured by CEUS never fully recovers after hindlimb surgery, even when followed 28–150 d postsurgery. Individual mice can manifest different patterns of muscle perfusion to the same surgery, but these patterns are conserved within and between different surgical techniques. These results may have significant implications for the evaluation of novel therapeutics to treat PAD in mice.

Variable practice patterns in the surgical management of renal hyperparathyroidism

BackgroundHyperparathyroidism is common among patients with chronic kidney disease, end-stage kidney disease, and kidney transplant. The American Association for Endocrine Surgery published clinical practice guidelines that address the surgical treatment of secondary and tertiary hyperparathyroidism. The purpose of this study is to determine practice patterns for the surgical management of secondary and tertiary hyperparathyroidism prior to guideline publication. MethodsWith the approval of the American Association for Endocrine Surgery, a Qualtrics email survey was sent to the Association’s membership in 2022 about current clinical decision making for surgical treatment of secondary and tertiary hyperparathyroidism. Respondents were divided into groups based on surgical subspecialty (endocrine surgery versus non-endocrine surgery), yearly parathyroidectomy volume, and yearly parathyroidectomy volume for surgical treatment of secondary and tertiary hyperparathyroidism. Descriptive statistics were performed; the role of volume was evaluated. ResultsThere were 142 responses from 795 solicited email addresses (18% response rate); 114 (84%) identified as endocrine surgeons. The majority (62%) perform >50 parathyroidectomies yearly, but most perform <10 parathyroidectomies for surgical treatment of secondary and tertiary hyperparathyroidism per year (<10/y, 53.7%; 10–30/y, 41.9%; >30/y, 4.4%). Subtotal parathyroidectomy is most commonly performed for surgical treatment of secondary (83%) and tertiary (52%) hyperparathyroidism, but transcervical thymectomy variably performed for both. There was no consensus regarding starting calcitriol preoperatively (always 43%, never 25%, depends on vitamin D levels 24%) or stopping cinacalcet (2 weeks prior 28%, day of surgery 29%, postoperatively 20%). Surgeons who perform >10 parathyroidectomies per year for surgical treatment of secondary and tertiary hyperparathyroidism were less likely to consider the patient's preoperative vitamin D levels to inform their decision to start calcitriol before surgery (<10 cases/year, 34%; ≥10 cases/year 15%; P = .023), were more likely to have a postoperative hypocalcemia protocol managed by the surgical team (<10 cases/year, 49%; ≥10 cases/year, 58%; P = .029), and were more likely to use intraoperative parathyroid hormone monitoring for tertiary hyperparathyroidism (<10 cases/year, 70%; ≥10 cases/year, 87%; P = .046). ConclusionThe majority of respondents perform <10 parathyroidectomies yearly for surgical treatment of secondary and tertiary hyperparathyroidism. Subtotal parathyroidectomy was most commonly performed, but there was little other consensus regarding preoperative management, intraoperative decision-making, and postoperative care. Opportunity exists through guideline dissemination to improve heterogeneity of care provided to surgical treatment of secondary and tertiary hyperparathyroidism patients.

Intraneural Topography and Branching Patterns of the Common Peroneal Nerve: Studying the Feasibility of Distal Nerve Transfers.

Common peroneal nerve (CPN) disruption is the most common lower extremity nerve injury and results in gait disturbances and sensory paresthesias. The goal of this study is to describe branching patterns and the intraneural topography of the CPN to facilitate operative planning in CPN reconstruction. The CPN and its distal motor and sensory branches were dissected in 6 lower leg cadavers. Branching patterns and distances were recorded with the fibular head as the landmark. Histological review of the nerve cross sections helped characterize the intraneural topography within the fibular tunnel. The CPN distal branching patterns were highly variable. The tibialis anterior motor branch was found on average 9.6 cm distal to the fibular head. Despite the variable branching patterns, the fascicular topography of the CPN within the fibular tunnel was consistent. Proximal to the tunnel, the nerve has 3 major fascicles, which include the superficial peroneal motor, common sensory, and deep peroneal motor (DPN) fascicles from lateral to medial. Within the tunnel, the topography consolidates into the superficial peroneal motor and DPN major divisions-motor axons anteriorly and sensory axons posteriorly. The data presented provide clinically relevant information for the peripheral nerve surgeon where fascicular reconstruction of the nerve and neurolysis should focus on the anterior half of the nerve to restore ankle dorsiflexion. The nerve proximally is divided into 3 major fascicles compared with 2 distally. Surgeons may consider distal nerve transfers from the tibial nerve motor branches to the DPN or tibialis anterior motor branch.

Probing into the formation of brominated halonitromethanes from the intracellular organic matter of Anabaena during UV/chlorine disinfection

Eutrophication events in water bodies result in the release of algal organic matter, which is an essential precursor for halonitromethanes during disinfection, posing a significant threat to water quality. During UV/chlorine disinfection, the presence of Br− promotes the formation of brominated halonitromethanes (Br-HNMs), which exhibit higher toxicity compared to chlorinated halonitromethanes. Nevertheless, limited studies have been conducted on the Br-HNMs formation from algal precursors during UV/chlorine disinfection in the presence of Br−. Therefore, in this study, the formation pattern and toxicity variation of Br-HNMs from the intracellular organic matter (IOM) of anabaena during UV/chlorine disinfection was investigated. The results showed that monobromonitromethane, bromochloronitromethane, and bromodichloronitromethane could be detected during UV/chlorine disinfection. When the Br− concentration raised, the total concentration and toxicity of Br-HNMs exhibited an increase followed by a decline. Additionally, the concentration and toxicity of three Br-HNMs were promoted by increasing UV intensity, free chlorine dosage, and anabaena concentration but inhibited by increasing pH. Based on the experiment results, possible pathways for Br-HNMs formation from anabaena IOM in the presence of Br− were deduced. Moreover, anabaena IOM could also be converted to Br-HNMs during UV/chlorine disinfection of actual water, with a formation pattern similar to that found in distilled water. This research offers valuable insights into Br-HNMs formation from algal-containing waters.

Blowin' in the Wind: Mapping the Dispersion of Metal(loid)s From Atacama Mining.

The Atacama Desert's naturally elevated metal(loid)s pose a unique challenge for assessing the environmental impact of mining, particularly for indigenous communities residing in these areas. This study investigates how copper mining influences the dispersion of these elements in the wind-transportable fraction (<75μm) of surface sediments across an 80km radius. We employed a multi-pronged approach, utilizing spatial modeling to map element distributions, exponential decay analysis to quantify concentration decline with distance, regime shift modeling to identify dispersion pattern variations, and pollution assessment to evaluate impact. Our results reveal significant mining-driven increases in surface concentrations of copper (Cu), molybdenum (Mo), and arsenic (As). Notably, within the first 20km, concentrations peaked at 1,016mgkg⁻1 for Cu, 31mgkg⁻1 for Mo, and a remarkable 165mgkg⁻1 for As. Cu and Mo displayed significant dispersion, extending up to 50km from the source. However, As exhibited the most extensive reach, traveling up to 70km downwind, highlighting the far-reaching ecological footprint of mining operations. Mineralogical analyses corroborated these findings, identifying mining-related minerals in surface sediments far beyond the immediate mining area. Although pollution indices based on the proposed Local Geochemical Background reveal significant contamination across the study area, establishing accurate pre-industrial baseline values is essential for a more reliable assessment. This study challenges the concept of "natural pollution" by demonstrating that human activities exacerbate baseline metal(loid)s levels. Expanding monitoring protocols is imperative to comprehensively assess the combined effects of multiple emission sources, including mining and natural processes, in safeguarding environmental and human health for future generations.

Diversity and distribution of reed frogs (Hyperolius spp.) on Bioko Island, Equatorial Guinea

Reed frogs (Hyperolius spp.) are the most species-rich genus in the family Hyperoliidae, a group of frogs endemic to sub-Saharan Africa and the Gulf of Guinea islands. Three species are endemic to oceanic islands in the archipelago, but the diversity and distribution of reed frogs on Bioko – a land-bridge island in the archipelago – remains unclear. Two species, H. tuberculatus and H. ocellatus ocellatus, were formally documented on Bioko in the colonial era, however, two additional reed frog species have been detected in recent surveys. In addition, observations of heterospecific amplexus suggest one of the unidentified species and H. o. ocellatus may be hybridising on the island. In this study, we examined mitochondrial DNA (mtDNA), nuclear DNA (nuDNA), morphological and acoustic data to confirm the tentative identifications of the reed frogs and determine if there is any evidence of hybridisation. Our data confirm that the two unidentified species are H. endjami and H. fusciventris, and that Bioko H. endjami have unique genetic diversity not shared with the mainland population. Additionally, our mitochondrial (16S) and nuclear DNA (CMYC) haplotype networks suggest that H. o. ocellatus and H. endjami are not hybridising on Bioko. Finally, we report colour pattern variation in H. endjami and H. o. ocellatus that is unique from populations on the continent, and describe male advertisement calls of Bioko H. endjami and H. o. ocellatus. Our study provides a first look at the diversity and distribution of reed frogs on Bioko Island and sets the stage for future studies of the ecology, evolution, and conservation of this island community.

Dynamic response analysis of pipelines in gas distribution stations under seismic loads

Seismic loads in earthquake-prone regions significantly affect the structural integrity of pipelines at urban natural gas distribution stations, compromising safety. This study analyzes the dynamic response of pipelines in gas distribution stations under seismic loading and proposes effective measures to mitigate stress concentration. A numerical model of the pipeline in the gas distribution station, based on actual cases, was established. The material’s constitutive relationship was derived from tensile tests. The seismic response spectrum, obtained from ground motion data, was introduced to analyze the pipeline’s mechanical behavior. The dynamic response analysis identified critical stress concentration locations in the pipeline under operational conditions. Based on displacement analysis, the study recommended seismic measures. Results indicated that under seismic loading, higher stress values occurred primarily in pipeline sections with intricate flow pattern variations. The manifold connection was the most vulnerable point, with its average stress being 3.37 times that of the system’s average stress. The proposed seismic measures effectively reduced stress concentration at these critical points, mitigating the earthquake’s impact on the gas distribution station. This study establishes a theoretical framework for improving the seismic design and maintenance of natural gas distribution stations, enhancing their seismic resilience and operational safety.

Comparative analysis of electroencephalogram (EEG) data gathered from the frontal region with other brain regions affected by attention deficit hyperactivity disorder (ADHD) through multiresolution analysis and machine learning techniques

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by repeated patterns of hyperactivity, impulsivity, and inattention that limit daily functioning and development. Electroencephalography (EEG) anomalies correspond to changes in brain connection and activity. The authors propose utilizing empirical mode decomposition (EMD) and discrete wavelet transform (DWT) for feature extraction and machine learning (ML) algorithms to categorize ADHD and control subjects. For this study, the authors considered freely accessible ADHD data obtained from the IEEE data site. Studies have demonstrated a range of EEG anomalies in ADHD patients, such as variations in power spectra, coherence patterns, and event-related potentials (ERPs). Some of the studies claimed that the brain’s prefrontal cortex and frontal regions collaborate in intricate networks, and disorders in either of them exacerbate the symptoms of ADHD. , Based on the research that claimed the brain’s prefrontal cortex and frontal regions collaborate in intricate networks, and disorders in either of them exacerbate the symptoms of ADHD, the proposed study examines the optimal position of EEG electrode for identifying ADHD and in addition to monitoring accuracy on frontal/ prefrontal and other regions of brain our study also investigates the position groupings that have the highest effect on accurateness in identification of ADHD. The results demonstrate that the dataset classified with AdaBoost provided values for accuracy, precision, specificity, sensitivity, and F1-score as 1.00, 0.70, 0.70, 0.75, and 0.71, respectively, whereas using random forest (RF) it is 0.98, 0.64, 0.60, 0.81, and 0.71, respectively, in detecting ADHD. After detailed analysis, it is observed that the most accurate results included all electrodes. The authors believe the processes can detect various neurodevelopmental problems in children utilizing EEG signals.

Night life: Positional behaviors and activity patterns of the Neotropical kinkajou, Potos flavus (Carnivora, Procyonidae)

AbstractStudying positional behaviors is important for understanding how animals interact with their immediate environment. This is particularly important in arboreal species since arboreal milieus are primarily characterized by three‐dimensional problems that arboreal species must overcome to efficiently access resources. Similarly, a fundamental aspect of an animal's ecology is its daily activity pattern. This information is important for understanding the basic ecology of animal species and their eco‐evolutionary dynamics. This study sought to understand the habitat use and nocturnal lifestyle of the highly arboreal kinkajou (Potos flavus) by documenting variation in positional behaviors and activity patterns using 2223 photographs obtained from 27 camera traps in French Guiana. Data were analyzed using descriptive statistics, Kernel density estimation (KDE), and Gantt charts. Our results indicate that kinkajous show a strictly nocturnal activity pattern beginning from 19:00 h to 05:57 h, with peak active periods between 01:00 h and 02:00 h. The most frequent activities were scanning (48.33%) and traveling (47.13%). Quadrupedal walking (95.43%) was the main locomotor behavior during traveling. However, when crossing gaps between two substrates, kinkajous would either bridge (42.22%), leap (33.33%), or drop (26.67%) across gaps. Inactive periods were characterized by grooming (77.32%) and resting (27.84%) while mostly assuming a sitting (90.67%) or a catlike body curl posture (92.59%), interchangeably. This study highlights the broad array of positional behaviors displayed by kinkajous, further providing information to understand its basic ecology and eco‐evolutionary dynamics.

Comparative Proteomic Analysis of Wild and Cultivated Amaranth Species Seeds by 2-DE and ESI-MS/MS.

Amaranth is a promising staple food that produces seeds with excellent nutritional quality. Although cultivated species intended for grain production have interesting agronomic traits, relatively little is known about wild species, which can prosper in diverse environments and could be a rich genetic source for crop improvement. This work focuses on the proteomic comparison between the seeds of wild and cultivated amaranth species using polarity-based protein extraction and two-dimensional gel electrophoresis. Differentially accumulated proteins (DAPs) showed changes in granule-bound starch synthases and a wide range of 11S globulin isoforms. The electrophoretic profile of these proteins suggests that they may contain significant phosphorylation as post-translational modifications (PTMs), which were confirmed via immunodetection. These PTMs may impact the physicochemical functionality of storage proteins, with potential implications for seed agronomic traits and food system applications. Low-abundant DAPs with highly variable accumulation patterns are also discussed; these were involved in diverse molecular processes, such as genic regulation, lipid storage, and stress response.

Temporal dynamics of leaf area index and land surface temperature correlation using Sentinel-2 and Landsat OLI data

BackgroundUnderstanding the complex relationship between vegetation dynamics and land surface temperature (LST) is crucial for comprehending ecosystem functioning, climate change impacts, and sustainable land management. Hence, this study conducts a temporal analysis of leaf area index (LAI) and LST data derived from Sentinel-2 and Landsat Operational Land Imagery (OLI) in the Mille River Basin, a tropical region in Ethiopia. LAI data were generated using Sentinel-2 imagery processed with the Sentinel Application Platform (SNAP) toolbox, an open-access earth observation analysis tool, while Landsat OLI collection 2 level 2 data were utilized for precise LST retrieval. The Mann–Kendall test was used to detect trends in the time series data.ResultsThe trends in the mean LAI were statistically significant at P values of 0.05 and 0.10 for the annual and seasonal trends, respectively. The mean LST trends were insignificant throughout the study period except for the summer season, for which the P value was 0.07. The correlation between the LAI and LST was weak (R2 = 0.36) during the crop-growing seasons (summer and spring) but moderate in winter (R2 = 0.46) and autumn (R2 = 0.41).ConclusionThe findings of this research clarify the complex relationships between variations in surface temperature and vegetation growth patterns, providing insight into the environmental mechanisms driving the dynamics of localized ecosystems. The study underscores the implications of these findings for informed decision-making in sustainable land management, biodiversity conservation, and climate change mitigation strategies.

Anatomic variations of the supinator nerve for transfer to the posterior interosseous nerve in tetraplegia.

The anatomy of the supinator nerve was evaluated in 20 fresh-frozen cadavers. Variations in branching patterns, number of motor branches and distance of the branch points from the radial nerve relative to the radiocapitellar joint are described.

Extracellular Vesicle-Based Characterization of Stem Cell Phenotype in Glioblastomas.

Glioblastoma (GB) is the most common brain malignancy occurring in adult patients having an extremely low overall survival. Therefore, it is paramount to establish reliable and accurate diagnostic and prognostic markers to guide a personalized and more effective treatment. Molecular characterization of the tumor is the ultimate goal in GB management and comprises, among others, the study of the extracellular vesicles (EVs). Not only do they carry within their cargo molecules involved in shaping a favorable microenvironment for GB development, but EVs also present surface markers mirroring the phenotype of the donor cells. Our study aims to assess the dynamic evolution of EV-positive surface biomarkers and EV-derived proteins involved in maintaining and transferring a stem cell phenotype to the cells from GB surroundings. We performed a prospective observational study on GB patients operated on in the Neurosurgery Clinic of the Emergency Clinical County Hospital of Târgu Mureș, Romania. GB-derived EVs were isolated from the patients' plasma using a density gradient ultracentrifugation protocol. The expression of EVs positive to four epitopes specific to stem cells (CD44, CD133, CD326/EpCAM, and SSEA4) was followed in three moments in time, preoperatively, seven days, and three months postoperatively, respectively, and quantified by a bead-based multiple analysis using flow cytometry. Moreover, NANOGP8, a protein within GB cargo capable of promoting a stem cell phenotype, was dynamically evaluated using the Western blot technique. Our study showed a statistically significant decrease of all surface markers and NANOGP8 immediately after tumor ablation. Nonetheless, the long-term follow-up of the patients revealed an extremely variable evolutionary pattern reflecting the high heterogeneity of GB. Further studies are necessary to either confirm or infirm the accuracy of these markers in early diagnosing GB, in predicting the outcome of this disease, and in guiding an individualized therapy.
