Rating scales and linear indices of surface electromyography (sEMG) cannot quantify all neuromuscular conditions associated with ankle-foot dysfunction in hemiplegic patients. This study aimed to reveal potential patients by nonlinear network sEMG. Fourteen male hemiplegia 10 age- sex-matched healthy adults were recruited tested static standing position. The characteristics the root mean square (RMS), median frequency (MF), three indices, clustering coefficient (C), average shortest path...

Abstract. Functional trait databases are emerging as a crucial tool for wide range of ecological studies, including next-generation vegetation modelling across the world. However, few large-scale studies have been reported on plant traits in Tibetan Plateau (TP), cradle East Asian flora and fauna with specific alpine ecosystems, no report could be found. In this work, an extensive dataset 11 leaf functional (TiP-Leaf), mainly herbs shrubs trees TP, was compiled through field surveys. The...

Abstract The changes of balance control mechanism caused by lumbar disc herniation (LDH) has not been well understood. This study aimed to investigate the effects LDH on during standing sloped surfaces. Ten patients with and 10 gender- age-matched healthy subjects were instructed stand quietly a surface at −5°, 0° or +5°, respectively. trajectories center pressure (COP) each individual limb full-body recorded. Cross recurrence quantification analysis (CRQA) was applied assess coordination...

To observe changes of correlations gait parameters four sets body in children aged 3-6.A cross-sectional observational study.Dong Gang kindergarten Suzhou, China.A total 89 between 3 and 6 years old.A 37 three-dimensional (3-D) assessed with a wearable analysis system 2-min walking test, for times.There were significant differences speed, stride length sagittal range motion (ROM) trunk among 3-6 old (P < 0.05). The left right toe out angle, ROM waist, coronal arm swing velocity male...

Wearable inertial sensors are considered to be low cost, portable and user-friendly for gait assessment. But relatively little is known about their reliability validity compared with the other well-established, sophisticated techniques. This study aimed determine of an sensor system (APDM Mobility Lab). A total 20 participants were commanded take a 10-m walk at self-selected speeds. series parameters collected analyzed by this wearable analysis three-dimension (3-D) motion simultaneously....

Abstract Background There is currently no objective and accurate clinical assessment of reticular neuromuscular control in healthy subjects or patients with upper motor neuron injury. As a result, dysfunctions could just be semi-quantified, efficacies mechanisms various therapies for improving are difficult to verify. Methods Fourteen participants were required maintain standing balance the kinetostatics model Gusu Constraint Standing Training (GCST). A backward upward constraint force was...

A disintegrin and metalloproteinases (ADAMs), a family of transmembrane glycoproteins, are expressed in numerous tissues organs, have been implicated variety physiological pathological processes. ADAM15 is unique among the ADAMs having an Arg-Gly-Asp motif its domain. In present study, antitumor anti-angiogenic effects recombinant human domain (rhdd) ADAM15, by Escherichia coli, were evaluated. rhddADAM15 inhibited proliferation migration several tumor cells, with half maximal inhibitory...

The motor function of the upper limb is typically impaired in stroke patients; as a result, rehabilitation exercise crucial to regaining muscular control. While encouraging patients continue with long-term using standard training methods may be difficult. To deal this dilemma, virtual reality (VR) games are introduced motivate take part therapy. Meanwhile, music therapy has been proven extremely beneficial early phases recovery. These activities inspire us include musical instrument play...

Congenital obstructive nephropathy is the primary cause of chronic renal failure in children. Disorders mitochondrial energy metabolism may be a factor underlying tubular cell apoptosis hydronephrosis. The β-F1-ATPase (ATP5B) and electron transfer flavoprotein β subunit (ETFB) metabolic markers are involved other diseases. aim present study was to evaluate whether ATP5B ETFB represented hydronephrotic kidney, they associated with progression cohort examined consisted 20 children...

In order to regain the motor control of upper limbs, stroke patients should go through various exercises resume finger, hand and arm functions. During such exercises, they need constant assistance, guidance support from either therapists or caregivers. Due increase aging population, demand for technology in home-based recovery has rapidly increased last decade. This paper presents an interactive prototype designed facilitate finger grasping, gripping reaching at home. It consists a portable...

Human placenta was obtained from early onset preeclampsia, late and their gestational age-matched normal pregnancy. Using RT-qPCR, western blot, immunohistochemistry, it demonstrated that miR-21 expressions were significantly decreased in preeclampsia while RASA1 increased. Suppression of placental HTR-8/SVneo cells, remarkably upregulated RASA1, proliferation, inhibited invasion, promoted apoptosis trophoblast overexpression alleviated these effects. Dual-luciferase reporter assays revealed...

The overall muscle activation of post-stroke patients during standing has not been well understood. Functional network provides a tool to quantify the functional synchronization across large number muscles. In order investigating stroke survivors quiet standing, we recruited 8 hemiplegic and required them stand still for 30 s with eyes open closed. Surface electromyography signals were recorded from 16 muscles in abdomen, buttocks lower limbs. networks paretic side healthy built by multiplex...

Purpose: To observe both the linear and nonlinear indices of electromyography calf muscles in healthy adults plantar flexion.Methods: Linear sEMG including root mean square (RMS), median frequency (MF), indices, degree centrality (DC) ten male participates were tested rest state flexion position to unrevealed characteristics muscles.Results: The RMS was not normally distributed, MF DC values distributed. Compared state, RMS, all significantly higher(P<0.05) flexion. Among muscles, PL changed...

患者男，69岁。主要症状为腹痛和发热。腹部磁共振成像检查显示肝左叶异常信号，初步考虑肝脓肿或肝内胆管癌。穿刺肝组织镜下9个汇管区均见炎性细胞浸润，汇管区血管内见异型淋巴细胞增生，细胞体积大，空泡状核，核仁明显，核分裂象易见，呈非肝血窦内生长模式。免疫组织化学结果示肿瘤细胞位于血管腔内，并表达CD20等B淋巴细胞标志物。B淋巴细胞基因克隆性重排阳性。肝脏血管内大B细胞淋巴瘤呈非肝窦内生长模式病例罕见，易被漏诊或误诊，诊断时需与反应性炎症、转移性低分化癌或上皮样血管内皮瘤等鉴别。确诊需要依赖于组织形态学、免疫组织化学和基因重排等多方面的综合分析。.

A given movement requires precise coordination of multiple muscles under the control center nervous system. However, detailed knowledge about changing characteristics neuromuscular for multi-muscle in post-stroke hemiplegic patients during standing is still lacking. This study aimed to investigate hemiplegia-linked dysfunction from perspective dynamical by utilizing a novel network approach – weighted recurrence (WRN). Ten male with first-ever stroke and 10 age-matched healthy adults were...

Limb-girdle muscular dystrophy (LGMD) is usually confused with idiopathic inflammatory myopathy (IIM) in clinical practice.
