Characteristics and course of lower extremity muscle activity in a patient with body lateropulsion due to pontine infarction: a case report.

Background: Body lateropulsion (BL) is a phenomenon in which the body involuntarily falls to one side; however, its detailed postural control characteristics remain unclear.

Objective: This case report aimed to measure the surface electromyography (EMG) of the lower limbs while standing in a patient with severe BL on the affected side due to pontine infarction and to investigate the characteristics of postural control.

Case Description: We evaluated a patient with severe BL due to pontine infarction at two-time points, 6 and 20 days after onset, to assess static standing balance under open and closed eye conditions and measure the center of pressure (COP) and lower extremity EMG during these tasks.

Investigating the association between sitting ability, trunk electromyography, and sitting posturography in patients with acute stroke: A cross-sectional study.

Background: Sitting ability is an important prognostic factor for patients with acute stroke. However, the characteristics of trunk muscle activity and weight-bearing during sitting are unclear.

Research Question: Are trunk muscle activity and weight-bearing during static sitting associated with sitting ability in patients with acute stroke?

Methods: Trunk electromyography and sitting posturography were performed during static sitting in 20 patients with acute stroke.

Prognostic Factors for the Postoperative Improvement of Spinal Cord-Related Neuropathic Pain in Patients with Degenerative Cervical Myelopathy.

Introduction: The number of patients with degenerative cervical myelopathy (DCM) requiring surgical treatment has markedly increased in today's aging society. Such patients often exhibit impaired activities of daily living because of motor dysfunction as well as neuropathic pain (NeP). Although many studies have demonstrated the safety and efficacy of surgical treatment for DCM, residual postoperative NeP has not been well described.

Clinical impact of short limited lumbar fusion for adult spinal deformity with postural and radiological abnormalities.

Extensive surgical spinopelvic fusion for patients with adult spinal deformity (ASD) to achieve optimal radiological parameters should be avoided. The aim of this study was to review clinical and imaging findings in patients with ASD with postural and radiological abnormalities who underwent a novel three-level limited lumbar fusion as two-stage surgery in an attempt to propose a better tolerated alternative to spinopelvic long fusion to the pelvis. The subjects were 26 patients with a minimum follow-up period of 2 years.

Combining transcranial direct current stimulation and peripheral electrical stimulation to improve upper limb function in a patient with acute central cord syndrome: a case report.

We report the immediate improvement of weakened muscles after combined treatment with transcranial direct current stimulation (tDCS) and peripheral electrical stimulation (PES) in a patient with acute central cord syndrome (CCS) who presented with severe upper limb motor dysfunction. A 70-year-old man sustained CCS with severe motor deficits in the left upper limb, which did not improve with conventional training until 6 days after injury. On the seventh day after the injury, the left upper limb was targeted with combined tDCS (1 mA for 20 minutes/day, anode on the right, cathode on the left) and PES (deltoid and wrist extensors, 20 minutes/day at the motor threshold), and his performance score immediately improved from 0 to 6 on the Box and Block test.

Center of pressure velocities in patients with body lateropulsion: three case report series of Wallenberg's syndrome.

Purpose: In patients with Wallenberg's syndrome who present with body lateropulsion (BL), whether the center of pressure (COP) position and velocity characterize postural dysregulation is unknown. We measured time-course changes in COP parameters in three BL patients.

Methods: Three patients with acute Wallenberg's syndrome presented with BL.

Carboxylative Cyclization of a Propargylic Amine with CO Catalyzed by a Silica-Coated Magnetite.

By employing a silica-coated magnetite as a catalyst, a silica-catalyzed carboxylative cyclization of propargylic amines with carbon dioxide (CO) proceeded to afford the corresponding 2-oxazolidinones. Moreover, after the reaction, the silica-coated magnetic catalyst was readily recovered by use of an external magnet and could be reused up to six times without deactivation.

J Strength Cond Res 36(2): 379-385, 2022-Muscle blood volume increases due to stretching; however, the minimum duration of stretching to sustainably increase the muscle blood volume after stretching has not yet been elucidated.

Stereoretentive Ligand Exchange Reactions of N-Fused Porphyrin Ruthenium(II) Complexes.

The ligand exchange reactions of the ruthenium(II) complex of N-fused tetraphenylporphyrin, Ru(NFp)(CO)Cl (2), with various anions were investigated. The chloride ligand of the isomers 2a-c was stereoretentively exchanged with bromide (Br), iodide (I), and acetate (AcO) anions in toluene at 100 °C, structures of which were confirmed by H NMR as well as single crystal X-ray diffraction analysis. The silver (AgOAc, AgOTf) and boron (NaBPh) reagents also afforded the corresponding stereoretentive products.

Increased Anterior Pelvic Angle Characterizes the Gait of Children with Attention Deficit/Hyperactivity Disorder (ADHD).

Background: Children with attention deficit/hyperactivity disorder (ADHD) frequently have motor problems. Previous studies have reported that the characteristic gait in children with ADHD is immature and that subjects demonstrate higher levels of variability in gait characteristics for the lower extremities than healthy controls. However, little is known about body movement during gait in children with ADHD.

Ruthenocene-Type Complexes of N-Fused Porphyrins.

Ruthenocene-type hybrid complexes with N-fused porphyrinato ligands, [Ru(NFp)Cp] (NFp=N-fused porphyrin, Cp=cyclopentadienyl), have been prepared and characterized by NMR and UV/Vis/NIR spectroscopy, cyclovoltammetry, and X-ray crystallography. [Ru(NFp)Cp] is a common low-spin ruthenium(II) complex and shows strong aromaticity. The Ru-Cp distance (1.

Early transplantation of mesenchymal stem cells after spinal cord injury relieves pain hypersensitivity through suppression of pain-related signaling cascades and reduced inflammatory cell recruitment.

Bone marrow-derived mesenchymal stem cells (BMSC) modulate inflammatory/immune responses and promote motor functional recovery after spinal cord injury (SCI). However, the effects of BMSC transplantation on central neuropathic pain and neuronal hyperexcitability after SCI remain elusive. This is of importance because BMSC-based therapies have been proposed for clinical treatment.

Early transcutaneous electrical nerve stimulation reduces hyperalgesia and decreases activation of spinal glial cells in mice with neuropathic pain.

Although transcutaneous electrical nerve stimulation (TENS) is widely used for the treatment of neuropathic pain, its effectiveness and mechanism of action in reducing neuropathic pain remain uncertain. We investigated the effects of early TENS (starting from the day after surgery) in mice with neuropathic pain, on hyperalgesia, glial cell activation, pain transmission neuron sensitization, expression of proinflammatory cytokines, and opioid receptors in the spinal dorsal horn. Following nerve injury, TENS and behavioral tests were performed every day.

Synthesis and isomerization of N-fused tetraphenylporphyrin ruthenium(II) complexes.

Three possible isomers of N-fused tetraphenylporphyrin ruthenium complexes, Ru(NFTPp)Cl(CO)2 (2a-c), were isolated and fully characterized by NMR, IR, CV, UV-vis-NIR absorption, and X-ray crystallographic analyses. Each isomer was stable at ambient conditions and isomerization among 2a-c occurred at elevated temperature both in solution and in a solid state, through the intramolecular rotational pathways. Electronic structures of 2a-c were analyzed in detail by DFT study to reveal appreciable differences in the interaction between the NFTPp ligand and the Ru-Cl moiety.

Postoperative gait analysis and hip muscle strength in patients with pelvic ring fracture.

The aims of present study were (1) to determine changes in kinematic and kinetic variables at 3 and 12 months after open reduction and internal fixation (ORIF) of pelvic ring fracture and (2) to determine the factor(s) associated with gait disorders that correlate with gait parameters measured at 12 months after surgery. Nineteen patients with pelvic ring fractures underwent ORIF and examined at 3 and 12 months postoperatively. The study also included a similar number of age-matched control subjects.

Microvascular system of the lumbar dorsal root ganglia in rats. Part I: a 3D analysis with scanning electron microscopy of vascular corrosion casts.

Object: So far, the morphological features of the vascular system supplying the dorsal root ganglion (DRG) have been inferred only from microangiograms. However, in the past most of these studies lacked 3D observations. This study presents the details of the microvasculature of the lumbar DRG visualized by scanning electron microscopy of vascular corrosion casts.

Diagnosis and discrimination of autoimmune Graves' disease and Hashimoto's disease using thyroid-stimulating hormone receptor-containing recombinant proteoliposomes.

Graves' disease (GD) is an autoimmune disease of the thyroid gland caused by autoantibodies against thyroid-stimulating hormone receptor (TSHR). Currently, the diagnostic test for TSHR autoantibodies is based on an indirect competitive binding assay that measures the ability of TSHR autoantibodies to inhibit the binding of thyroid-stimulating hormone (TSH) to TSHR. Here, we have developed a specific and direct diagnostic method for autoantibodies in GD that incorporates immobilized TSHR-containing recombinant proteoliposomes into an enzyme-linked immunosorbent assay (ELISA).
