A total 997 students from freshmen seniors were selected for study using a cluster random sampling method. The following tools used: Self-Concept Clarity Scale, Learning Engagement Sense Life Meaning Future Orientation Questionnaire. results indicated that...

(1) Background: Ultrasound has been used for noninvasive stimulation and is a promising technique treating neurological diseases. Epilepsy common disorder, that attributed to uncontrollable abnormal neuronal hyperexcitability. Abnormal synchronized activities can be observed across multiple brain regions during seizure. (2) Methods: we low-intensity focused ultrasound (LIFU) sonicate the brains of epileptic rats, analyzed EEG functional network explore effect LIFU on network, continued...

The cerebral cortex plays an important role in human and other animal adaptation to unpredictable terrain changes, but little was known about the functional network among cortical areas during this process. To address question, we trained 6 rats with blocked vision walk bipedally on a treadmill random uneven area. Whole-brain electroencephalography signals were recorded by 32-channel implanted electrodes. Afterward, scan from all using time windows quantify connectivity within each window...

ABSTRACT Background Immune system modulation has been shown to have a significant impact on attention deficit hyperactivity disorder (ADHD). Mendelian randomization (MR) analysis was used in this study investigate the potential role of different immune cells development ADHD provide therapy and preventative alternatives. Methods In study, 731 risk were examined using publicly accessible genetic data two‐sample MR analysis. Included four types immunological profiles: determinate (DC),...

Background: The objective of this study was to investigate the biochemical impact laparoscopic surgery on angiogenesis, focusing vascular endothelial growth factor (VEGF), and modulation key tumor markers in patients with early-stage ovarian cancer. Methods: A total 76 diagnosed early cancer were enrolled divided into two groups based surgical approach: control group (n=38) underwent open surgery, observation surgery. Surgical parameters, VEGF levels, [matrix metalloproteinase 9 (MMP9),...

Phase-amplitude coupling (PAC) measures the interaction between neural oscillations in different frequency bands and reflects brain functional network coordination psychiatric patients. The event-related dynamic changes PAC characteristics their association with physiological mechanisms under emotional stimulation major depressive disorder (MDD) remain poorly understood. We proposed a cross-sectional study that investigated three methods using simulated data selected Gaussian-Copula...

The objective of this study is to investigate the relationship between meaning in life and adolescent self-control, as well role perceived social support gender pathway.For purpose, a total 936 adolescents from two high schools were selected subjects study. Meaning Life Scale, Self-Control Perceived Social Support Scale used for research.The results obtained have shown that significant positive predictor self-control support. In addition, partially mediates self-control. Further, it has been...

Data from a longitudinal questionnaire investigation of three time waves were used to investigate affective and behavioral changes their covariant relationship among Chinese general population during the COVID-19 pandemic March May 2020. 145 participants aging 15 63 completed survey. Latent growth curve analyses found that negative affect gradually increased as continued. A faster increase in was related greater decrease adaptive behavior non-adaptive behavior. higher initial level slower

Peripheral nerve stimulation is an effective neuromodulation method in patients with lower extremity movement disorders caused by stroke, spinal cord injury, or other diseases. However, most current studies on rehabilitation using sciatic focus solely ankle motor regulation through of common peroneal and tibial nerves. Using the electrical method, we here achieved muscle control via different branches to facilitate limb movements during stepping standing. A map relationships between muscles...

Abstract Rotary draw bending is a CNC tube process widely used in industry. Compared with pure bending, rotary involves much more complex loading condition. In addition to the moment, an axial force generated even if no drawing externally applied. Taking this into account, paper presents analysis of bending. The stress distribution and wall thinning are calculated. Calculations compared experimental numerical results good agreement shown.

The Body Image Concern Inventory (BICI) was developed to assess dysmorphic appearance concern and has been found be a reliable valid instrument in Western societies. To examine the psychometric properties of new Chinese BICI, BICI administered 1,231 young adults (Study 1) 47 female patients with eating disorders 56 matched controls (ED; Study 2). In study 1, Cronbach’s alpha .92 test-retest reliability .73 over 6-month interval observed for total scale. Confirmatory factor analysis supported...

Epilepsy is common brain dysfunction, where abnormal synchronized activities can be observed across multiple regions. Low-frequency focused pulsed ultrasound has been proven to modulate the epileptic network. In this study, we used two modes of low-intensity (pulsed-wave and continuous-wave) sonicate brains KA-induced rats, analyzed EEG functional connections explore their respective effect on network, discuss mechanism neuromodulation. By comparing network characteristics before after...

Background.Transcutaneous electrical nerve stimulation (TENS) is generally applied for tactile feedback in the field of prosthetics. The distinct mechanisms evoked perception between stimulus patterns conventional TENS (cTENS) and neuromorphic (nTENS) are relatively unknown. This first study to investigate neurobiological effect nTENS cortical functional mechanism perception.Methods.Twenty-one healthy participants were recruited this study. Electroencephalogram (EEG) was recorded while...

The formulation of maintenance strategies for gas turbines requires an accurate and rapid assessment damaged blade performance. Variety uncertainty in the three-dimensional geometric deformation turbine vanes blades increase difficulty degradation analysis. In this paper, effects on aerodynamic performance partial damage to nozzle guide are investigated experimentally numerically. A methodology constructing a deformation–degradation model high-pressure vanes/blades is proposed based machine...

Although brain structural changes have been reported in patients with obsessive-compulsive disorder (OCD), results from previous studies inconsistent. A growing number of focused on obsessive beliefs and impulsivity which could be involved the occurrence maintenance OCD symptoms. The present study aimed to examine whether there are distinct different subgroups.Eighty-nine 42 healthy controls were recruited undergo magnetic resonance imaging scan. classified into subgroups according scores...

Neural interfaces typically focus on one or two sites in the motoneuron system simultaneously due to limitation of recording technique, which restricts scope observation and discovery this system. Herein, we built a with various electrodes capable large spectrum electrophysiological signals from cortex, spinal cord, peripheral nerves, muscles freely moving animals. The integrates adjustable microarrays, floating microwires commercial connector cuff electrode wireless transmitter. To...
