Objective: Low intensity focused stimulation (LIFUS) has been proved to improve motor function in Parkinson's disease (PD) animal modules. The aim of this study is to investigate whether LIFUS target on the primary motor cortex (M1) can improve motor deficit in the PD rats.

Methods: The PD rat model was induced by injection of 6-hydroxydopamine (6-OHDA) in the medial forebrain bundle (MFB).

Dielectric energy storage capacitors are indispensable components in advanced electronic and electrical systems. Excellent performance requires the dielectric materials possessing low residual polarization (P), high breakdown strength (E), and large maximum polarization (P). The first two parameters can be typically achieved through chemical regulation, while the P is closely related to the matrix.

Tungsten bronze oxides have emerged as attractive materials for energy storage owing to their fast charge-discharge property. However, the internal weakness of low capacity and short cycling performance impedes their development in wide application. In this work, the tungsten bronze WNbO nanorods with preferred orientation (001) were prepared by hydrothermal method for the first time.

Article Synopsis
  • The paper introduces a new model for understanding how humans interact with exoskeletons by focusing on muscle activation and its effect on coupling parameters.
  • It utilized a new experimental platform and involved 20 volunteers while monitoring their muscle activity through surface electromyography (EMG) signals to identify important coupling parameters.
  • A convolutional neural network (CNN) was used to analyze six EMG features, revealing that certain features (AR, MAV, and VAR) are crucial for predicting coupling parameters, with a noted strong correlation between coupling stiffness and MAV/VAR.

PlZAT10-PlCYP707A2 module promotes Paeonia lactiflora seeds germination. The herbaceous peony (Paeonia lactiflora) seeds exhibit double dormancy in the epicotyl and hypocotyl, which significantly inhibits the process of cultivation and breeding of new varieties. Nevertheless, the molecular mechanism underlying seed dormancy release in P.

Background: Transcutaneous electrical acupoint stimulation (TEAS) may contribute to blood pressure (BP) control, but the evidence remains insufficient. Our objectives were to evaluate the impact of TEAS on hypertension and determine the optimal frequency.

Methods: A total of 120 hypertensive patients were randomly allocated to the TEAS-2Hz group, TEAS-10Hz group, or usual care control group in a 1:1:1 ratio.

Maternal inheritance of mitochondrial DNA (mtDNA) is a widespread phenomenon in eukaryotes. Our earlier research indicated that sperm mtDNA is removed prior to fertilization in mice, and Endonuclease G (ENDOG) orchestrates the degradation of sperm mitochondria in Caenorhabditis elegans. However, the mechanisms underlying sperm mtDNA disposal in mammals remain poorly understood.

Article Synopsis
  • Clinical prediction models are valuable tools intended to improve clinical decision making, but their use in practice is limited due to issues like incomplete data in electronic health records (EHR).
  • The article proposes a new submodel approach that enhances prediction model application by refining the model coefficients to better handle real-time data inconsistencies.
  • Simulation results indicate that this new method performs well across different scenarios and is better suited for practical implementation than existing methods, specifically in identifying emergency department patients with acute heart failure eligible for safe discharge.

Despite the gradual development of students' sedentary habits and associated health problems, only a few studies have extensively and systematically measured campus built environments (CBE) and their impact on street walking activity. This study explores the association between CBEs and pedestrian volume (PV). Comprehensive questionnaires, field audits, and GIS were used to measure the CBE variables and PV of 892 street segments on eight Chinese campuses in Tianjin.

Microplastics pose a serious ecological threat to rivers in China, and the construction of a large number of dams has complicated this problem. Ten dams of the Shaying River were chosen to investigate the abundance and composition of microplastics in surface water and sediments of the reservoir and upstream river. Ecological risk was evaluated using species sensitive distribution (SSD) and pollution load index (PLI).

Both lymphatic vessels and macrophages are key factors influencing the inflammatory response. During the inflammatory response, lymphatic vessels undergo dilation and growth, playing a beneficial role in alleviating inflammation by facilitating the drainage of exudate, inflammatory mediators, and leukocytes. Consequently, the promotion of lymphangiogenesis has emerged as a novel therapeutic approach to treating inflammation.

Background: Numerous insect species undertake long-distance migrations on an enormous scale, with great implications for ecosystems. Given that take-off is the point where it all starts, whether and how the external light and internal circadian rhythm are involved in regulating the take-off behaviour remains largely unknown. Herein, we explore this issue in a migratory pest, Cnaphalocrocis medinalis, via behavioural observations and RNAi experiments.

Anionic redox chemistry can surpass theoretical limits of conventional layered oxide cathodes in energy density. A recent model system of sodium-ion batteries, O3-NaLiMnO, demonstrated full anionic redox capacity but is limited in reversibility and kinetics due to irreversible structural rearrangement and oxygen loss. Solutions to these issues are missing due to the challenging synthesis.

The study employed event-related potential (ERP), time-frequency analysis, and functional connectivity to comprehensively explore the influence of male's relative height on third-party punishment (TPP) and its underlying neural mechanism. The results found that punishment rate and transfer amount are significantly greater when the height of the third-party is lower than that of the recipient, suggesting that male's height disadvantage promotes TPP. Neural results found that the height disadvantage induced a smaller N1.

Background: Persistent macrophage infiltration may lead to adverse consequences, such as calcifications and nodules in fat grafts. Lymphatic vessels, which transport inflammatory cells, are involved in regulating inflammatory responses. Less is known, however, about lymphatic vessels after fat grafting.

Hypertension is a global problem threatening human health and life. Although there are many antihypertensive drugs, the low compliance of medication affects its efficacy, and the effect in regulating hypertension has become increasingly prominent. Focusing on the new trend of proactive healthcare management, in the present paper, we made a summary about the status and existing problems of transcutaneous electrical acupoint stimulation (TEAS) in the regulation of blood pressure, and put forward some suggestions, such as selecting acupoints based on classical acupuncture theory to highlight the advantages of TEAS to control blood pressure as a whole, optimizing and screening the parameters of TEAS in the regulation of blood pressure, expanding the research observation indexes etc.
