Authors: Li Zibo , Zhang Guohua , Li Yubo , Zhou Wenjun , Qin Tao , Zeng Li , Liu Gang
Published: October 2023

This paper aims to investigate the coal thickness change area of the combined rock strata energy accumulation law. The method of connecting a uniaxial compression experiment with a theoret-ical analysis is used in this work. We employ a combination of coal and rock to carry out our studies. We investigate how different lithologies and ratios of coal-rock height affect the me-chanical properties of the mixture and the law governing energy accumulation. We have deter-mined the following facts: (1) The combination's peak strength and elastic modulus exceed that of coal and are inferior to that of rock but are nearer to that of coal. (2) When the coal-rock height ratios are dissimilar, the peak strength and modulus of elasticity of the combination show a negative correlation with the coal-thickness share, and the pre-peak energy accumulation and impact energy index of the combination shows a positive correlation with the coal-thickness share. (3) For the combination with the same coal-rock height ratio, the peak strength, elastic modulus, pre-peak energy accumulation, and impact energy index all increase with greater rock strength and elastic modulus. The presence of a hard rock layer affects the accumulation of pre-peak energy. ( 4 ) The stress in the surrounding rock gradually decreases as the coal thick-ness increases. In the area where coal thickness declines, the stress in surrounding rock is higher than that in the region where it thickens. The energy stored in the surrounding rock is directly proportional to the coal in the zone. Conversely, areas with thinner coal deposits exhibit a lower energy storage capacity in the surrounding rock than those with thicker coal deposits. The stress distribution of surrounding rock in coal thickness change is abnormal; substantial energy accu-mulation can swiftly initiate dynamic disasters, such as rock bursts. This study has important reference significance for preventing and controlling rock burst in coal thickness change areas.

Authors: Dachang Zhu , Yonglong He , Xuezhe Yu , Fangyi Li
Published: October 2023

Delta parallel robot has been widely used in precision parts processing, handling, sorting, and precision assembly, with high efficiency and motion stability being its important performance indexes. Any small line segment corner in trajectory planning causes tangential discontinuous trajectory abrupt change, and the process vibration and shock caused by it seriously affect its high-speed and high-precision performance. In this paper, a trajectory planning method combining Cartesian space and joint space is proposed. Firstly, the vector method and micro-element integration method are used to establish the complete kinematics and dynamics equations of the Delta parallel robot, and the inverse kinematics/dynamics model-solving program is written based on Matlab software. Secondly, the end-effector trajectory of the Delta parallel robot is planned in Cartesian space, and the data points and inverse control points of the end-effector trajectory are obtained by the normalization method. Finally, the data points and control points are mapped to the joint space through the inverse kinematics equation, and the fifth-order B-spline curve is adopted for quadratic trajectory planning, which realizes the high-order continuous smoothing of trajectory planning. The simulation and experiment results show that the trajectory smoothing performance of continuous high-order curvature change can be improved using the proposed method, the tracking error of the end-effector is reduced by 21.12%, and the peak torques change of three joints is reduced by 3.5%, 11.6% and 1.6%, respectively.

Authors: Farfán Córdova Marlon Gastón , Díaz Ortega Jorge Luis
Published: October 2023

This article is a scoping review analyzing advances in experimental studies on bacterial self-healing of concrete. From Scopus, ScienceDirect, Web of Science and Google Scholar search engine databases, 54 studies were selected for analysis, and an increasing trend of publications since 2015 was found, with India as the country with the largest research presence. Different ma-terials are used as replacement or admixture in concrete, such as fibers, particles and recycled material from construction waste. It was found that the most commonly used bacteria are Bacillus subtilis and Bacillus sphaericus, which can improve the strength of concrete by generating calcite and sealing cracks. In addition, it was found that the presence of materials such as fibers, ashes and construction recyclates can protect bacteria in an alkaline environment. The designs usually in-clude more than two experimental groups and a control. In summary, this study highlights the importance of bacterial self-healing in concrete and provides information on advances in this field of research.
Effects of Soil and Water Conservation Practices and Slope Gradient on Selected Soil Physicochemical Properties in the Northwestern Ethiopia
Authors: Atinafu Mamaru , Getnet Kassie , Gojjam Amare
Published: October 2023

Soil erosion is the major factor that has contributed to the reduction of soil fertility in the highlands of Ethiopia. This factor was reduced by soil and water conservation (SWC) practices. Hence, the study evaluated the effects of SWC practices and slope gradient on soil physicochemical properties in the Agemi watershed of northwestern Ethiopia. Farmland treated by SWC such as stone-faced soil bund (SFSB) and soil bund (SB), untreated farmland and slope gradient were identified in the study area. About 27 soil samples were collected from the treated farmland and untreated farmland with three slope classes, including lower (5-10%), middle (10-15%) and upper slopes (>15%). The soil physicochemical properties were analyzed by two ways analysis of variance (ANOVA) using SAS 9.2. The results of the study showed that the content of sand, clay, total porosity, pH, soil organic matter (SOM), total nitrogen (TN), available phosphorus (AP), exchangeable cations such as Ca2+, Mg2+, K+ and cation exchange capacity (CEC) were significantly affected (p<0.01) by SWC practices and untreated farmland with slope gradients. However, the content of silt, percent of base saturation (PBS) and exchangeable Na were statistically insignificant (p>0.05). Farmland treated with SFSB confirmed higher mean values of soil physicochemical properties than SB and untreated farmland. Moreover, the lower total porosity (TP) and higher bulk density (BD) were recorded on untreated farmland and upper slopes. This study concludes that farmland treated with SFSB improved soil physicochemical properties than farmland treated with SB followed by untreated farmland. Therefore, SFSB should be implemented on farmland to improve soil fertility in the study area.

Cannabis induced psychosis: A comparative study between cannabis use disorder and cocaine use disorder
Authors: Coppola Maurizio , Mondola Raffaella
Published: October 2023

Psychosis can be defined as a combination of psychopathological symptoms including delusions and/or hallucinations without insight. Psychotic disorders may configure a primary psychiatric illness or represent the result of a functional/structural brain damage induced by substance use, neurological diseases or other medical conditions. They are multifactorial disorders in which genetic, environmental and gene-environment interaction factors contribute to the expressiveness of the symptoms. Among the environmental factors, psychotropic substances represent the most important removable facilitators of psychosis. In our study, we compared the prevalence of substance induced psychosis between a sample of patients affected by cannabis use disorder and a sample of patients affected by cocaine use disorder analyzing retrospectively the data of outpatients with no personal or family history of psychiatric illnesses.
Quantum Spacetime Geometrization: Qed at High Curvature and Supermassive Black Holes in the Early Universe
Authors: Chiarelli Piero
Published: October 2023

In this work, the author employs the quantum hydrodynamic formalism to achieve the geometrization of spacetime for describing the gravitational interaction within the framework of quantum theory. This approach allows for the development of an equation of gravity that is mathematically connected to the fermion and boson fields. This achievement is accomplished by incorporating two fundamental principles: covariance of the quantum field equations and the principle of least action. By considering these principles, a theory is established that enables the calculation of gravitational corrections to Quantum Electrodynamics, and potentially, to the standard model of particle physics as well. The theory also provides an explanation for two phenomena: the existence of a cosmological pressure density similar to quintessence, that is compatible with the small value of the observed cosmological constant, and the breaking of matter-antimatter symmetry at high energies offering insights into why there is an imbalance between the two in the early universe. In the cosmological modeling of the theory, there exists a proposal to account for the formation of supermassive black holes that are accompanied by their own surrounding galaxies, without relying on the process of mass accretion. The model, in accordance with recent observations conducted by the James Webb Space Telescope, supports the notion that galactic configurations were established relatively early in the history of the universe, shortly after the occurrence of the Big Bang.

Authors: Karakaş Levent , Poçan Süheyl
Published: October 2023

Background: This study aimed to contribute to the standardization of elastography by comparing stiffness values obtained from ultrasound elastography (US-E) and magnetic resonance elastography (MR-E) of the testicular parenchyma in healthy subjects. Methods: A total of 22 healthy volunteers (44 testes) were included in this study. Of the 26 cases analyzed, four were excluded from the study due to the exclusion criteria. The testicular parenchyma of the included patients was evaluated using MR-E and Shear-Wave Ultrasound Elastography (SW-E) examinations. Pearson's correlation test was used to calculate the correlation between age and stiffness values, testicular volumes and stiffness values, and stiffness values from both examinations. Results: The mean US-E stiffness of the right testes was 5.560 ± 3.1 kPa and the mean US-E stiffness of the left testes was 5.361 ± 2.9 kPa. The mean MR-E stiffness of the right testes was 6960.11 ± 460 Pa and the mean MR-E stiffness of the left testes was 6560.19 ± 310 Pa. There was no significant correlation between US-E and MR-E stiffness values (p=0.096). There was also no significant statistical correlation between US-E and MR-E stiffness values and testicular volumes (p=0.17 and p=0.093). Conclusions: No statistical correlation was found between the stiffness values obtained by SW-E and those obtained by MR-E in the normal testicular parenchyma. Additionally, no conclusive relationship between stiffness levels, age, or testicular volume was discovered.

Authors: Desta Getnet , Molla Esubalew
Published: October 2023

Coastal ecosystems provide a wide range of goods and services for the lives of human beings and aquatic species. Nevertheless, climate-induced extreme events cause unprecedented impacts on these areas, instigating a reduction of aquatic goods and services, destruction of infrastructure, and loss of human lives. Hence, this review investigated the impacts of climate-induced coastal hazards and adaptation responses. A systematic review method was used to address the objectives of this literature review. The main data sources were Research Gate, Google Scholar, Scopus, Web of Science, and PubMed databases. A total of 40 research articles (2012-2023) were selected using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA 2020) methodology. The findings of this review revealed that Bangladesh was the leading country based on the number of studies published on the impacts of climate-induced coastal hazards and coastal adaptations (20%), followed by the USA, which accounts for about 15%. Sea-level rise, coastal flooding, and climate change and variability were the most studied climate-induced coastal hazards, each accounting for 55%, 52.5% and 52.5% respectively. Coastal hazards have had significant impacts on the fishery, water, coastal ecosystems and biodiversity, agriculture, tourism, and infrastructure sectors. Besides, they caused migration and death of humans and animals. About 35% of the articles explored the assessment of vulnerability to climate-induced hazards. Moreover, 32.5% of the articles investigated anticipated climate-induced hazards. Hard, soft, ecosystem-based, and hybrid adaptation measures were used to adapt to the impacts of diverse climate-induced coastal hazards. In conclusion, developing countries are more vulnerable to the adverse impacts of climate-induced coastal hazards than developed countries. The coastal area’s vulnerability to climate change risks will continue unless all stakeholders act proactively. Thus, it is suggested that the adaptation policies of vulnerable coastal areas should give due attention to nature-based solutions to reduce the adverse impacts of coastal hazards sustainably.

Authors: Rasuli Mohammad Azim , Torii Shuichi
Published: October 2023

This study investigates the role of insulation, in commercial buildings and how it affects energy efficiency and sustainability in different climate regions. Commercial buildings consume an amount of energy making them ideal candidates for energy saving measures. Insulation plays a role in maintaining indoor conditions reducing energy usage and minimizing carbon emissions by limiting heat transfer through the building’s envelope. By conducting simulations using the Hourly Analysis Program (HAP) this research examines how insulation thickness, climate conditions and building characteristics impact energy consumption and greenhouse gas emissions. The study covers climate zones with a focus on Afghanistan, semi-arid, arid and mountainous regions where sustainable construction practices are highly important. The findings demonstrate that insulation has an effect on enhancing energy efficiency particularly when it comes to heating. Additionally, economic factors, future research directions and broader implications, for construction practices are thoroughly discussed. Considering that the construction industry contributes significantly to carbon emissions this research provides insights into promoting sustainable building practices. By optimizing insulation strategies, architects, builders and policymakers can reduce the impact of commercial buildings while advancing energy efficiency and supporting a more sustainable urban future.

Published: October 2023

We introduce linear probing hashing schemes that construct a hash table of size $n$, with constant load factor $\alpha$, on which the worst-case unsuccessful search time is asymptotically almost surely $O(\log \log n)$. The schemes employ two linear probe sequences to find empty cells for the keys. Matching lower bounds on the maximum cluster size produced by any algorithm that uses two linear probe sequences are obtained as well.

Prognostic significance of peripheral blood S100A12, S100A8, and S100A9 concentrations in idiopathic pulmonary fibrosis
Authors: Ding Dongyan , Luan Rumei , Xue Qianfei , Yang Junling
Published: October 2023

Background: S100A12, S100A8, and S100A9 are inflammatory disease biomarkers whose functional significance in idiopathic pulmonary fibrosis (IPF) remains unclear. We evaluated the significance of S100A12, S100A8, and S100A9 levels in IPF development and prognosis.
Methods: The dataset was collected from the Gene Expression Omnibus (GEO) database and differentially expressed genes were screened using GEO2R. We conducted a retrospective study of 106 patients with IPF to explore the relationships between different biomarkers and poor outcomes. Pearson’s correlation coefficient, Kaplan–Meier, Cox regression, and functional enrichment analyses were used to evaluate relationships between these biomarkers’ levels and clinical parameters or prognosis.
Results: Serum levels of S100A12, S100A8, and S100A9 were significantly elevated in patients with IPF. The two most significant co-expression genes of S100A12 were S100A8 and S100A9. Patients with levels of S100A12 (median 231.21 ng/mL), S100A9 (median 57.09 ng/mL) or S100A8 (median 52.20 ng/mL), as well as combined elevated S100A12, S100A9, and S100A8 levels, exhibited shorter progression-free survival and overall survival. Serum S100A12 and S100A8, S100A12 and S100A9, S100A9 and S100A8 concentrations also displayed a strong positive correlation (rs2 = 0.4558, rs2 = 0.4558, rs2 = 0.6373; P < 0.001). S100A12 and S100A8/9 concentrations were independent of FVC%, DLCO%, and other clinical parameters (age, laboratory test data, and smoking habit). Finally, in multivariate analysis, the serum levels of S100A12, S100A8, and S100A9 were significant prognostic factors (hazard ratio 1.002, P = 0.032, hazard ratio 1.039, P = 0.001, and hazard ratio 1.048, P = 0.003).
Conclusions: S100A12, S100A8, and S100A9 are promising circulating biomarkers that may aid in determining IPF patient prognosis. Multicenter clinical trials are needed to confirm their clinical value.
The Combined Effects of Inter-Basin Water Transfer and Land Use Change on Water Supply-Demand Risk
Authors: Zhao Yuhang , Zhao Xuehua , Guo Qiucen , Wu Wenyu , Ren Zhijing
Published: October 2023

Water yield service is a critical component of ecosystem services, Assessing the associated risks with its supply and demand is a current research focus. However, limited studies have investigated the influence of multiple factors on the risk of water yield service. This study proposes an evaluation framework for the supply and demand risk of water yield service considering the combined effects of inter-basin water transfer (IBWT) and land use/cover change (LUCC). This study takes the Fen River Basin as an example to reveal the spatial heterogeneity of the risk under multiple influencing factors. Results show that by 2030, the demand for water yield service in the Fen River Basin will increase significantly due to the occupation of farmland by artificial land. Without considering IBWT, by 2030, the artificial land area is mostly in a state of level III and level II extremely endangered in terms of water supply and demand risk. Considering IBWT, by 2030, the artificial land will be transformed into a level IV danger state, and a large number of dispersed areas of level IV danger in the plain region will be transformed into a level V shortage of supply state. Overall, the water supply and demand risk show a downward trend. The results of the geodetector analysis shows that under the influence of IBWT, the explanatory power of influencing factors such as LUCC for the risk have been significantly improved.

Leukemias are genetically heterogeneous and diagnostics therefore includes various standard-of-care (SOC) techniques, including karyotyping, SNP-array and FISH. Optical genome mapping (OGM) may replace these as it detects different types of structural aberrations simultaneously and additionally detects much smaller aberrations (500 bp vs. 5–10 Mb with karyotyping). However, its resolution may still be too low to define clinical relevance of aberrations when they are located between two OGM labels or when labels are not distinct enough. Here, we test the potential of Cas9-directed long-read sequencing (LRS) as an additional technique to resolve such potentially relevant new findings. From an internal Bionano implementation study we selected ten OGM calls that could not be validated with SOC methods. Per variant we designed crRNAs for Cas9 enrichment, prepared libraries and sequenced them on a MinION/ GridION device. We could confirm all aberrations and, importantly, the actual breakpoints of the OGM calls were located between 0.2–5.5 kb of the OGM-estimated breakpoints, confirming the high reliability of OGM. Furthermore, we show examples of redefinition of aberrations between labels that enable judgment of clinical relevance. Our results suggest that Cas9-directed LRS can be a relevant and flexible secondary technique in diagnostic workflows including OGM.

Authors: Patchaiyappan Arunkumar , Singh Abhishek , Bautes Nicolas , Abimannan Arulkumar
Published: October 2023

In the present study, face mask littering was assessed in sixteen stations across the beaches in Coromandel coast of South India for a period of four weeks. In terms of land use pattern, stations with both fishing and tourism activities had higher abundance of face mask littering when compared with exclusive fishing and tourism stations. Parallelly, face mask littering in the streets of the coastal hamlets were also assessed and compared with the beach face mask littering. The study found that mask littering was higher in streets when compared to the beaches. Moreover, an online questionnaire was recorded to evaluate the people perception about face mask usage and littering. Of 183 respondents, most of the respondents preferred using disposable single use masks and 39.9% of the respondents preferred to dispose the face masks along with other wastes. The study highlights the lack of proper solid waste management, negligent littering, and the need for raising awareness, strategic intervention to control this menace.
Multi-Physics-informed deep learning approach for computational structural mechanics
Authors: Kong Xuan , He Weiwei , Li Jinzhao , Deng Lu
Published: October 2023

Finite element method (FEM) has been popular for decades for structure analysis by solving partial differential equations (PDEs). Recently, physics-informed deep learning has emerged as a promising approach for solving PDEs and shows great advantages over FEM in the computational efficacy. However, it is still a challenge for the structural mechanics computation since it involves solving higher-order PDEs as the governing equations are fourth-order nonlinear PDEs. Therefore, we develop a novel multi-physics-informed neural network (m-PINN) framework via combining multiple neural networks (NNs) where each NN representing physics information such as geometrical compatibility, constitutive relation, and static equilibrium. The verification result demonstrates that m-PINN has the same accuracy as FEM for the computation of beam and shell structures. The proposed method has the potential to be a new paradigm in the structural mechanics computation as an alternative of FEM, and could serve as an intelligent computational module in digital twin system.

The objective was to study the correlations between intake and deposition of fatty acids in the Longissimus dorsi muscle of crossbred steers supplemented on pasture. Thirty-two steers in the finishing phase were distributed in a completely randomized design, with four treatments composed of concentrate supply levels (0.2; 0.4; 0.6; and 0.8% of body weight) and 11 animals per treatment. Dietary C12:0 fatty acid showed positive correlations with C17:0, C14:1 and C17:1 acids and negative correlations with C18:3 n-3 acid deposited in the muscle. Dietary C17:0 acid showed positive correlations with C17:0, C14:1, C15:1, C17:1 acids deposited in the meat and negative correlations with the n-6/n-3 ratio. Dietary fatty acid C18:2n-6 showed positive correlations with fatty acids C17:0, C14:1, C15:1, C17:1 and C18:3n-3. Dietary C18:3n-3 fatty acid showed positive correlations with fatty acids deposited in muscle C17:0, C14:1 and C17:1. Dietary C20:5n-3 fatty acid showed positive correlations with fatty acids deposited in muscle C17:0, C14:1, C15:1 and C17:1. Dietary C20:4n-6 fatty acid showed negative correlations with fatty acids deposited in muscle C17:0, C14:1, C17:1 and C18:3n-3. The fatty acids present in the diets correlated with most of the fatty acids deposited in the Longissimus dorsi muscle. There was an increase in the deposition of monounsaturated fatty acids and a reduction in the ratio between n-6 and n-3 series fatty acids.

Background and Aim
The use of beneficial bacteria, such as purple non-sulfur bacteria (PNSB), has shown great potential for improving plant growth and agricultural production. However, the full extent of their benefits and interaction with agricultural practices is yet to be fully understood. The present study aimed to investigate the synergistic effects of PNSB and crop rotation on rice growth and yield in a field setting and to explore the underlying plant and soil mechanisms by which these practices can benefit farming systems.
Methods
The experiment was conducted over two rice cropping seasons, with djulis grown between the rice crops as a rotation crop. Data on the growth and yield of rice was collected and statistically analyzed using a one-way analysis of variance (ANOVA) and Duncan's multiple range test.
Results
The study demonstrates that PNSB treatment significantly increased the concentration of 5-aminolevulinic acid (5-ALA) in plants, indicating enhanced photosynthesis. Moreover, when combined with crop rotation, PNSB remarkably improved soil fertility. These combined benefits resulted in substantial increases in tiller numbers (163%), leaf chlorophyll content (13%), and lodging resistance (66%) compared to the control. The combined treatment also resulted in higher productive tillers per hill (98%), average grain per hill (106%), and grain fertility (37%). This led to increased grain yield (104%), shoot dry weight (28%), and harvest index (54%).
Conclusion
Our study indicates that a combined approach of PNSB inoculation and crop rotation can effectively enhance the growth and yield of rice plants. These findings have significant implications for sustainable rice production and could potentially contribute to addressing global food security challenges. Improving plant growth and yield could help meet the increasing demand for rice in the face of a growing global population.
Research on fault diagnosis method of aviation bearing based on improved DRSN
Authors: Chen Weixing , He Kun
Published: October 2023

Aiming at the traditional bearing diagnostic methods with complex arithmetic and low accuracy. In this paper, an improved deep residual shrinkage network model is designed by integrating the advantages of long short-term memory network (LSTM) and deep residual shrinkage network (DRSN). Firstly, the original one-dimensional vibration signal is imported into the LSTM module to fully extract the timing features, and then the extracted feature information is convolved and imported into the residual shrinkage network module for deep feature mining, and finally the classification of faults is accomplished based on the fully connected layer. The model is validated on the aviation bearing dataset, and the experimental results show that compared with the traditional DRSN network model, the improved model proposed in this paper not only saves 93.7% of the running time, but also achieves 97.4% of the fault diagnosis accuracy; at the same time, in the presence of noise interference, the model proposed in this paper still has a higher accuracy compared with other methods. Therefore, the model proposed in this paper not only saves a lot of time, but also has better robustness and accuracy.

Objective
SARS-Cov-19-pandemic totally changed daily routine work in German hospitals. As hospital capacity was reduced, many surgeries were postponed or even cancelled. On March 25th 2020 the German Society of Neurosurgery (DGNC) published a statement in which urgent non-elective surgeries were defined for each neurosurgical domain, whereas elective interventions were deferred. The present work examines the impact of these Covid strategies focusing on patients with peripheral lesions who were conducted to our department during this period of time.
Methods
All patients, who underwent any peripheral nerve surgery at our department from January 2018 until December 2022, were included. The complete range of surgeries including peripheral nerve lesions was examined encompassing compression syndromes, traumatic lesions of brachial plexus, traumatic lesions and tumors of single peripheral nerves. The numbers of surgical procedures were compared before, during and after pandemic. Pearson correlation coefficient was analysed.
Results
From 2018 to 2022 the total number of surgical procedures involving peripheral nerves included 2422 procedures. Compression syndromes made up the largest proportion (1433 operations, 59%), followed by peripheral nerve lesions (445 operations, 18%), peripheral nerve tumors (344 operations, 14%) and lesions of the brachial plexus (142 operations, 6%). The average was 40,5 interventions per month, the range was 7–63. Two declines in the number of peripheral nerve surgeries were noted during this period. The first was in April and May 2020 with an average drop of 65% and 41% respectively. In these months the average number of operations was 37. The second decrease was from October 2021 until January 2022, where number of surgeries was reduced by 16%, 36%, 83% and 18% with an average number of 50 operations. Both declines showed a significant and strong correlation with the lower number of compression syndrome treatments (r = 0.952, p < 0.001 and r = 0.968, p < 0.001), while no drop and no significant correlation was found in the treatment of traumatic peripheral nerve injuries (p = 0.769, r = 0.095 and p = 0.243, r = 0.366) and traumatic brachial plexus injuries (p = 0.787, r = 0.088 and p = 0.780, r = 0.09). A weak significant correlation was seen in the treatment numbers of peripheral nerve tumors (p = 0.017, r = 0.672 and p = 0.015, r = 0.67).
Conclusion
Covid-19 pandemic lead to a significant decrease in the number of nerve decompressions, since, according to the German Society of Neurosurgery, those were considered as elective surgeries.

Published: October 2023

Psychedelics are promising therapeutics for mood disorders due to their rapid, sustained results. These effects rely on serotonin (5-hydroxytryptamine) receptor agonism, especially at the 2A receptor (5-HT2AR). Human neuroimaging studies have reported dramatic 5-HT2AR-dependent changes in functional brain reorganization that presumably reflect neuromodulation. However, the potent vasoactive effects of serotonin have not been considered. We assessed neuronal, hemodynamic, and neurovascular coupling (NVC) effects of the psychedelic 5-HT2AR agonist, 2,5-Dimethoxy-4-iodoamphetamine (DOI), using wide-field optical imaging (WFOI) in awake Thy1-jRGECO1a mice during stimulus-evoked and resting-state conditions. While DOI mildly altered tasked-based NVC, more pronounced NVC alterations occurred under resting-state conditions and were strongest in association regions. Further, calcium and hemodynamic activity reported different accounts of RSFC changes under DOI.Co-administration of DOI and the 5-HT2AR antagonist, MDL100907, reversed many of these effects. Dissociation between neuronal and hemodynamic signals emphasizes a need to consider neurovascular effects of psychedelics when interpreting blood-oxygenation-dependent neuroimaging measures.

Published: October 2023

Anterior open bite refers to the opposing incisors do not come into contact. Skeletal class II malocclusion is characterized by maxillary protrusion, mandibular retrusion, or both. These two types of malocclusion can affect the patient’s facial appearance, masticatory function and mental health. They are big challenges to orthodontists and orthognathic surgery is usually needed to solve these problems. This case report describes an adult patient with the facial-skeletal problem of anterior open bite, narrow upper arch and skeletal Class II malocclusion, and malocclusion of severe dentition crowding, impacted premolars and posterior crossbite, meanwhile with periodontitis (stages III, grade B). The multidisciplinary management included teeth removing, maxillary skeletal expansion, posterior teeth intrusion, en masse retraction of upper anterior teeth and without orthognathic surgery. The esthetic facial profile and proper occlusal relationship were obtained.
