Networks of marine protected areas (MPAs) are being increasingly implemented worldwide as conservation management tools. We report here on MPA effectiveness using a 16-year long ROV monitoring program spanning 24 MPAs across California’s MPA network. Our estimates show that MPA protection has a positive effect on the abundance of four demersal fish species with wide geographic distributions across the MPA network. We also demonstrate that there have been regional recoveries in abundance for these species outside of the MPAs. Our approach highlights the utility of remotely operated vehicles (ROVs) to support timely reporting on the effectiveness of MPA networks with quality monitoring data.

To strengthen the disaster prevention and control of engineering fractured rock mass in the cold region of western China due to freeze-thaw cycles, 20 freeze-thaw cycles were performed on fractured sandstone samples with different inclination angles of 30°, 45°, 60°, and 90°. Subsequently, conventional triaxial and fatigue loading tests were conducted to explore the mechanical properties and fracture morphology evolution mechanism of freeze-thaw fractured sandstone during compression. At the same time, nuclear magnetic resonance technology was used to analyze the microscopic damage characteristics. Based on the internal variable theory of continuum mechanics, a fatigue model of freeze-thaw fractured sandstone with different inclination angles was established. The results show that the sandstone strength is negatively correlated with the fracture dip angle, the axial deformation and shear failure angle are positively correlated with the fracture dip angle. The mechanical properties of the sandstone are deteriorated by fatigue loading. The T 2 spectrum distribution of the fractured sandstone mainly has three peaks, and the pore distribution is mainly medium and small pores. There is a small leftward shift after freeze-thaw cycles and fatigue loading. The T2 spectral area is significantly affected by freeze-thaw cycles and fatigue loading, and the rate of change of both tends to increase. Through the fine correspondence between the axial residual deformation and the deformation modulus, a fatigue model with different crack inclination angles was established using the axial residual deformation as the internal variable, and the rationality of the model was verified by fatigue loading tests.

composite right /left-handed transmission line metamaterial leaky wave antenna with ability of space scan by changing frequency and at a fixed frequency with lumped element is designed in this study. Considering the ability to rotate antenna beam by changing the frequency of the leaky wave antenna, the rotation of the desired antenna pattern was evaluated by changing the frequency. The introduced antenna can scan a wide spatial area from 〖-15〗^° to 〖+42〗^° by changing the frequency in the 2.5 GHz bandwidth (from 9 to 11.5 GHz) without a stop band and with maximum gain of 15 db. In the second part, by placement three Lumped elements (capacitors) in each unit cell of mentioned CRLH-TL leaky wave antenna that has the ability to scan the space in several fixed frequencies (9.6-10-10.4-11 GHz) has been designed. In this case, the antenna can scan from 〖-5〗^° to 〖+12〗^° at 9.6 GHz and from 〖-18〗^° to 〖-46〗^° at 11 GHz with an average gain of 11 db. For wider scanning in negative and positive angles, it is suggested to use a double-port switch to feed from both inputs of the CRLH-TL leaky wave antenna to increase the overall space scanning angle.

Subtropical moss peatlands have important ecological functions, and their protection and restoration are urgent. In this study, typical subtropical moss peatlands and the Cryptomeria swamp forest (CSF) formed by long-term (more than 20 years) drainage and afforestation in the Yunnan-Guizhou Plateau of China were selected as the research sites. 16S rRNA high-throughput sequencing technology was used to study the differences in soil bacterial community diversity and composition among a natural Sphagnum fen (SF), Polytrichum bog (PB) and CSF to explore the effects of drainage and afforestation on different types of moss peatlands and its mechanism combined with soil physicochemical properties. Results showed that (1) drainage and afforestation significantly reduced the α diversity of soil bacterial communities in SF, while significantly increased the α diversity of soil bacterial communities in PB. Soil bacterial communities of SF had the highest α diversity and had many unique species or groups at different taxonomic levels. (2) The impact of drainage and afforestation on the soil bacterial community composition in SF was significantly higher than that in PB. Drainage and afforestation caused significant changes in the composition and relative abundance of dominant groups of soil bacteria in SF at different taxonomic levels, such as significantly reducing the relative abundance of Proteobacteria, significantly increasing the relative abundance of Acidobacteria, and significantly reducing the ratio of Proteobacteria to Acidobacteria, but did not have a significant impact on the corresponding indicators of PB. The changes in the ratio of Proteobacteria to Acidobacteria may reflect changes in the trophic conditions of peatlands. (3) Soil moisture content, available phosphorus content, and pH were key driving factors for changes in soil bacterial community composition and diversity, which should be paid attention to in the restoration of moss peatlands.

INTRODUCTION: The treatment of moderate asthmatic exacerbations in children is controversial, specifically concerning whether ipratropium bromide (IB) should be combined with beta-2-short agonist and corticosteroids. In 2021, in our hospital, the use of IB was discontinued in moderate asthma exacerbation in our Pediatric Emergency Department (PED). OBJECTIVE: Compare the admission rate, average length of stay in the PED, Pulmonary Score (PS) at discharge, and revisits before and after discontinuing the use of IB in moderate asthmatic exacerbations. METHODS: single-center, retrospective, cohort study. Patients from 6 to 16 years who attended the PED with moderate asthmatic crisis (Pulmonary Score [PS]: 4-6) were included. Medical records were consulted in two periods: Cohort 1 (children received inhaled salbutamol, ipratropium bromide (IB) and systemic glucocorticoids, 01/09/2018-01/09/2019) and Cohort 2 (treatment with salbutamol and systemic glucocorticoids, 01/09/2021-01/09/2022) The relationship between the use of IB and the outcome variables was analyzed: admission rate and revisits (Chi-square), PED length of stay and PS score at discharge (Student’s T test). Multivariable analysis was performed to evaluate the potential association between variables and predictive factors for admission. RESULTS: 351 patients were included: 174 (49.6%) in Cohort 1 and 177 (50.4%) in Cohort 2. IB was not associated with admission rate (15 [8.6%] in Cohort 1 vs 7 [4%] in Cohort 2; p0.07), median stay in the PED (2.33hours [SD:0.66] vs 2,46 hours [SD:0.85], p0.207), Pulmonary Score at discharge (0,78 [SD:0.85] vs 0,92 [SD:0.79]; p0.137) nor revisits (25 [14,5%] vs 14 [7,9%]; p0.052); p0.207). CONCLUSION: IB does not seem useful in moderate asthmatic exacerbations.

Heart disease is significant global health concern. Coronary heart disease (CHD) is leading cause of mortality while medical interventions have significantly improved outcomes, there is a growing evidence to suggest that lifestyle modification play a pivotal role in preventing CHD. The molecular structure and properties of drugs play a critical role in maintaining heart disease. Additionally, we investigate potential implications of partition dimension in drug design and optimization. By examining the relationship between partition dimension and drugs molecular structure. We aim to identify molecular characteristics associated with enhanced drugs performance and reduced adverse effects. This research paper present a comprehensive analysis of the partition dimension molecular formula of heart disease drugs such as Metoprolol, Ivabrodin, Dapagliflosim, Empagliflotin and Vericiguate. To study the structural properties of these cardiac disease drugs and using the concept of partition dimension or partition metric Basis which involves identifying proper subsets of the entire vertex set to uniquely the whole structure of as a partition resolving set. This vertex metric resolvability approach helps in characterizing the properties of these cardiac disease drug structures.

Schizothoracine fish spawning habitats in the Tibetan Plateau are poorly understood but critical for conservation amidst anthropogenic threats and climate change. In a 2019–2021 study, we located the spawning grounds of Schizopygopsis microcephalus Herzenstein, 1891, at an astounding 4800 m above sea level, the highest known fish spawning site. This occurred in mid-June, before seasonal flooding. We found approximately six circular egg burial nests per square meter, measuring 20–30 cm in diameter and 10–15 cm deep, nestled within gravel (4–5 cm max diameter, D50 of 2.2 cm). Egg fertilization rates reached 98%, with an 82% hatching rate. Intriguingly, eggs displayed delayed shell hardening during natural incubation, possibly to protect against intense high-elevation ultraviolet radiation. Further investigations are needed to understand the role of the pliable membrane. Survival of the species requires that this kind of rare habitat be conserved.

Difficulty to extubate any patient is not a problem commonly thought of during general anaesthesia. This case report describes some of the factors that lead to this predicament and the successful surgical removal of the endotracheal tube via a tracheostomy. This case report also highlights some of the deficiencies in the clinical practice of veterinary anaesthesia. Further research is required for the selection size criteria of endotracheal tubes in all species and the monitoring of cuff pressures during general anaesthesia.

We conducted a multicentre hospital-based test-negative case–control study to measure vaccine effectiveness (VE) against PCR-confirmed influenza in adult patients with severe acute respiratory infection (SARI) during the 2022/23 influenza season in Europe. Among 5547 SARI patients ≥18 years, 2963 (53%) were vaccinated against influenza. Overall VE against influenza A(H1N1)pdm09 was 11% (95%CI: -23–36); 20% (95%CI: -4–39) against A(H3N2) and 56% (95%CI: 22–75) against B. During the 2022/23 season, while VE against hospitalisation with influenza B was >55%, it was ≤20% for influenza A subtypes. While influenza vaccination should be a priority for the upcoming season, improved vaccines against influenza are needed.

Influenza A(H3N2) viruses dominated early in the 2022–23 influenza season in Europe, followed by higher circulation of influenza A(H1N1)pdm09 and B viruses. The VEBIS primary care network estimated the influenza vaccine effectiveness (VE) using a multicentre test-negative study. Primary care practitioners collected information and specimens from patients consulting with acute respiratory infection. We measured VE against any influenza, influenza (sub)type and clade, by age group, by influenza vaccine target group and by time since vaccination, using logistic regression. We included 38,058 patients, of which 3,786 were influenza A(H3N2), 1,548 influenza A(H1N1)pdm09 and 3,275 influenza B cases. Against influenza A(H3N2), VE was 36% (95%CI: 25–45) among all ages, ranged between 30% and 52% by age group and target group. VE against influenza A(H3N2) clade 2b was 38% (95% CI: 25–49). Overall, VE against influenza A(H1N1)pdm09 was 46% (95%CI: 35–56) and ranged between 29% and 59% by age group and target group. VE against influenza A(H1N1)pdm09 clade 5a.2a was 56% (95% CI: 46–65) and 79% (95% CI: 64–88) against clade 5a.2a.1. VE against influenza B was 76% (95%CI: 70–81), overall; 84%, 72% and 71% among 0–14-year-olds 15–64-year-olds and those in the influenza vaccination target group, respectively. VE against influenza B with a position 197-mutation of the hemagglutinin (HA) gene was 79% (95% CI: 73–85) and 90% (95% CI: 85–94) without this mutation. The 2022–23 end-of-season results from the VEBIS network at primary care level showed high VE among children and against influenza B, with lower VE against influenza A(H1N1)pdm09 and A(H3N2).

Background: Pediatrics with cancer have higher mortality and morbidity rates than reported in general pediatrics who got infected by COVID-19, vaccination is a priority. Method: A random sample of 409 parents of pediatrics with cancer have been recruited, after obtaining IRB approval. A self-administered web-based cross-sectional survey was completed by them, and their demographic data have been collected as well. Results: Parents’ age and their pediatrics’ age play a significant role in their willingness to vaccinate their pediatrics who had cancer with the COVID-19 vaccine. Conclusion: A large proportion of parents are hesitant about the COVID-19 vaccine because they are less confident in its effectiveness, safety, and whether it is essential for their pediatrics. Keywords: COVID-19 vaccine; Cancer; Pediatrics; Vaccine hesitancy; Pediatric oncology.

Antibody mimetics is a novel antibody engineering approach after the development of polyclonal, monoclonal antibodies, and genetically engineered antibody fragments. Inspired by the structure and function of natural antibodies, antibody mimetics offer many advantages over conventional antibodies and can be constructed by protein-directed evolution, peptide design and synthesis, or fusion of complementarity-determining regions through intervening framework regions. A series of parent protein/peptide structures and technical roadmaps have been established to induce better recognising properties, superior affinity, stability, penetrability, and cost-effectiveness of the designed mimetics. This article aims to summarise the evolution of antibody mimetics engineering, illustrate the highlights and hotpots in this research field using scientometric analysis, and give an anticipatory analysis on this increasing research topic.

Selenium (Se) is an essential trace element that plays a critical role in maintaining human physiological metabolism. Among its various forms, selenium nanoparticles (SeNPs) have been found to possess higher degree of bioavailability and lower toxicity. This study screened 21 probiotics and identified a Se(IV)-resistant strain of Lacticaseibacillus paracasei SCFF20 that effectively converts sodium selenite (Na2SeO3) to SeNPs. The SeNPs produced by L. paracasei SCFF20 were purified, freeze-dried, and systematically characterized using SEM-EDX, DLS, XRD, Raman spectroscopy, and FTIR techniques. SEM–EDX analysis revealed that Se was the primary constituent of the biogenic nanoparticles. The synthesized SeNPs were spherical and polydisperse, with an average particle size of approximately 500.62 nm. XRD patterns and Raman spectroscopy confirmed the biologically amorphous nature of the fabricated nanoparticles. Additionally, FTIR spectral analyses demonstrated the presence of proteins, exopolysaccharides, and lipids coating the surface of the SeNPs. Moreover, the reduction rate of SeNPs, as measured by ICP-OES, was determined to be 91.42%. The findings of this study highlight the potential of L. paracasei SCFF20 as a probiotic capable of producing SeNPs, which can be used as a bio-factory for the safe production of biogenic SeNPs for nutritional supplements and functional foods.

DC-DC converters are key topologies in many industries such as renewable energy, transportations, utility, and perform an increasingly important role in the power electronics. The research of the modulation strategies with efficiency improvement is therefore critical for the DC-DC converters. As one of the most classic DC-DC converters, the dual active bridge (DAB) converter has attracted more and more attention in the utilization of the isolated DC-DC power conversion systems, due to its good performance. Over the past decade, many advanced techniques have been used to promote the efficiency for the DAB converter. Aiming to provide comprehensive analysis of different optimizing techniques for the DC-DC converters, this paper gives an overview of the efficiency optimization modulation strategies with a case study on the DAB converter. Firstly, typical phase-shift modulation methods and variable frequency modulation methods for the DAB converter are analyzed. After that, the application of three categories of optimization techniques are described, which including numerical optimization methods, metaheuristic methods and reinforcement learning (RL) methods. On this basis, this paper provides corresponding suggestions for further improving the operation efficiency of the DAB converters.

To address significant disturbances and unavoidable measurement noises during aeroengine transient tests in the Intake Environmental Pressure Simulation System (IEPSS), a sliding mode active disturbance rejection controller (SMADRC) is designed. Meanwhile, a particle swarm optimization (PSO) algorithm is adopted for optimizing and tuning the parameters of the proposed controller. Then, experiments are conducted on IEPSS simulation platform to verify the proposed method. The results demonstrate that the proposed controller has better noise tolerance and robustness, and eventually enhances the system comprehensive control performance.

This research introduces a Power Harmonics Suppression (Damping) based generation of reference currents for reliable operation of DFIGs with harmonic distortion in grid voltage. The imbalances and dominant harmonic components (negative sequence as well as 5 th and 7 th harmonics) in the grid voltage, induces stator active and reactive power oscillations of 200Hz, 300Hz, 400Hz and 600Hz. Further this lead to braking & forward torque and unreliable performance of DFIG aiding to grid instability issues. Thus, a modified set of current references are created for the d-q axes current control and these references are designed to reduce the imbalances and harmonics in electromagnetic torque, as well as stator active and reactive power, with a single objective of damping power oscillations. Simultaneously, the GSC is focused on mitigating fluctuations in the DC- link voltage while enabling UPF operation on the grid side. The novel current references for RSC and GSC are derived by incorporating negative sequence as well as 5 th and 7 th harmonic compensating currents along with the steady state current references, to acquire the desired targets. The overall system is validated with PSCAD/EMTDC simulations and using OPAL-RT OP4510 real-time simulator, on a 2.3kVA DFIG.

Cognitive and emotional dysfunction is a major complication in the later stages of Parkinson’s disease (PD). we planned to measure brain regional homogeneity (ReHo) by comparison with normal controls. Peak points in the regions of difference were then selected as seed ROIs, and whole-brain network abnormalities due to differences in local functional connectivity in PD patients were analyzed using granger causality analysis (GCA) to characterize the functional connectivity in PD patients without dementia symptoms to identify potential factors affecting cognition and mood in the disease. And voxel-based morphometry (VBM) was used to compare brain volumes in these abnormal functional areas and analyzed the correlation between functional and volumetric signals.The final results showed significant increase of regional functional connectivity in the orbit of the left inferior frontal gyrus, the orbit of the middle frontal gyrus, and the triangle of the left inferior frontal gyrus; the left precuneus, cuneus, superior occipital gyrus, and bilateral part of pons showed regional functional connectivity decreased. In the GCA, PD patients showed elevated functional connectivity from the bilateral precuneus to the left orbitofrontal lobe and reduced functional connectivity from the left cuneus to the left temporal pole. Furthermore, there were no significant differences and correlations between volumetric comparisons, and between functional and volumetric signals. Thus, the precuneus/cuneus may be an important integrative brain region for cognitive and emotional coordination and is an important factor in causing cognitive impairment and depression in PD patients.

Sodium-glucose cotransporter inhibitors (SGLT2 inhibitors) are novel drugs in the treatment of type 2 diabetes mellitus that prevent the absorption of glucose in the proximal tubules of the kidney and lower the blood glucose level. In addition to treating diabetes type 2, it influences all human systems. The aim of this study is to evaluate the effects of this drug (either beneficial or adverse) on all human systems, and based on that, a general opinion regarding the preference and safety of using this drug in diabetic patients with comorbidities, So far, no study has been conducted to evaluate the effects of this drug on all human systems. Its beneficial effects on improving cardiovascular disease risk factors and reducing adverse events caused by cardiovascular and renal diseases have proven in most large clinical studies that these effects are almost certain. It also has beneficial effects on other human systems such as the respiratory system, the gastrointestinal system, the circulatory system, and the nervous system; more of them are at the level of clinical and pre-clinical trials but have not been proven in large clinical trials or meta-analyses, so the term possible is used. In this review, the beneficial effects of this drug and its mechanism on every system of humans have been studied, and finally, its adverse effects have also been discussed. The key impact of this study is to attract the attention of large clinical studies based on an overview of all possible effects for the determination of certainty.

The rapid monitoring of food safety plays a key role in the food industry. Here, we have prepared a lanthanide metallo-organic framework Eu-TCPP, which can selectively detect aflatoxin B1, showing an ultrafast response of 5 min, a detection limit (LOD) of 44.17 ng/mL, and potential to develop point-of-care testing (POCT) sensing materials. Moreover, the emission wavelength of Eu-TCPP is at 617nm, which can effectively avoid aflatoxin autofluorescence interference, which is rarely reported in other mycotoxin fluorescence detection sensors. Combined experimental analysis and density functional theory (DFT) calculations show that the high selectivity, high sensitivity and rapid response ability of Eu-TCPP to detect aflatoxin B1 may be due to the LUMO level of the ligand higher than the LUMO level of aflatoxin, which transfers electrons to the object to be detected, resulting in weakened fluorescence. This study not only provides a potential probe for aflatoxin detection, but also providing a horizon that can guide the development of sensing materials for point-of-care testing (POCT) application.
