Planar array antenna coupled InGaAs/InAlAs multi-quantum well optical modulator for 60 GHz band millimeter wave signals.

A Fe-InP-based planar array antenna-coupled InGaAs/InAlAs multiple quantum well (MQW) optical phase modulator is proposed and demonstrated for radio over fiber (RoF) applications with 60 GHz-band millimeter-wave wireless signals. The modulator comprises five types of five-layer asymmetric coupled quantum wells (FACQWs) and a two-element array antenna. The FACQWs are designed to have a significant electric-field-induced refractive index change with small electric fields induced in the antenna.

Posterior Auricle Bilobed Cartilage-skin Flap for Reconstructing the Earlobe: A Case Report.

Because the auricle plays an important role in facial aesthetics, all earlobe operations must seek to limit postoperative ear deformity. This report describes the single-stage posterior-auricle bilobed cartilage-skin flap technique for reconstructing the earlobe. A 31-year-old man incurred a left earlobe deficiency due to a human bite.

Relationship between coordination variability and Osgood-Schlatter disease in male junior youth soccer players -cross-sectional study using an inertial measurement unit.

Background: Osgood-Schlatter disease is a common overuse injury, and motor coordination is discussed as a risk factor; however, no reports have examined motor coordination in young soccer players with Osgood-Schlatter disease. This study aimed to investigate the difference in motor coordination between Osgood-Schlatter disease-affected and non-affected soccer players on a junior youth soccer team.

Methods: This cross-sectional study investigated 35 young soccer players of 12-15 years of age, who completed a self-administered questionnaire covering general information, injury history, and athletic experience.

Nanobubbles in vase water inhibit transpiration and prolong the vase life of cut chrysanthemum flowers.

Nanobubble (NB) water has been shown to promote the growth of several types of plants and animals, but the mechanism underlying this promoting effect remains unclear. The present study evaluated the mechanism by which NBs maintain the freshness of cut flowers by keeping cut chrysanthemum ( Ramat.) flowers at the bud stage in vase water containing air NBs.

β Adrenergic Receptor Autoantibodies and IgG Subclasses: Current Status and Unsolved Issues.

A wide range of anti-myocardial autoantibodies have been reported since the 1970s. Among them, autoantibodies against the β-adrenergic receptor (βAR-AAb) have been the most thoroughly investigated, especially in dilated cardiomyopathy (DCM). ΒAR-Aabs have agonist effects inducing desensitization of βAR, cardiomyocyte apoptosis, and sustained calcium influx which lead to cardiac dysfunction and arrhythmias.

Fibroma of the tendon sheath in the dorsum of the foot: A case report.

Fibroma of tendon sheath (FTS) is a rare soft tissue tumor that usually occurs in the upper extremity. Moreover, of the few cases reported in the feet, nearly all occur in the plantar region. We report the case of a large FTS in the dorsum of the left foot that grew quickly into a 4 cm-diameter lesion.

[Early Experience with MRI-Ultrasound Fusion-Guided Prostate Biopsy in Our Institution].

A total of 100 patients were retrospectively analyzed with magnetic resonance imaging-ultrasonography (MRI-US) fusion biopsy(KOELIS, TRINITY®) at our institution between October 2019 and May 2020. The median patient age was 71 years, median prostate specific antigen (PSA) level was 7.4 ng/ml, and median PSA-density was 0.

The Progress of the Gait Impairment and Brain Activation in a Patient with Post-stroke Hemidystonia.

Objective: We explore the effects of body weight-supported (BWS) treadmill training, including the change of cortical activation, on a patient with post-stroke hemidystonia.

Patient: The patient was a 71-year-old man with left thalamus hemorrhage. His motor symptoms indicated slight impairment.

Early Recovery of Walking Ability in Patients After Total Knee Arthroplasty Using a Hip-Wearable Exoskeleton Robot: A Case-Controlled Clinical Trial.

Introduction: The Honda Walking Assist (HWA) is a hip-wearable exoskeleton robot for gait training that assists in hip flexion and extension movements to guide hip joint movements during gait. This study aimed to evaluate the effects of walking exercises with HWA in patients who underwent total knee arthroplasty (TKA).

Materials And Methods: This study involved 10 patients (11 knees) in the HWA group and 11 patients (11 knees) in the control group who underwent conventional physical therapy.

Gait Training Using a Hip-Wearable Robotic Exoskeleton After Total Knee Arthroplasty: A Case Report.

The Honda Walking Assist® (HWA) is a light and easy wearable robot device for gait training, which assists patients' hip flexion and extension movements to guide hip joint movements during gait. However, the safety and feasibility of gait training with HWA after total knee arthroplasty (TKA) remains unclear. Thus, we aimed to evaluate the safety and feasibility of this gait training intervention using HWA for a patient who underwent TKA.

Gait Training Using a Wearable Robotic Device for Non-Traumatic Spinal Cord Injury: A Case Report.

Introduction: We aimed to report the clinical evaluation results of gait training with the Honda Walking Assist Device (HWAT) in a patient with spinal cord injury (SCI).

Patients And Methods: A 63-year-old male with SCI (grade D on the American Spinal Injury Association Impairment Scale) underwent 20 HWAT sessions over 4 weeks. The self-selected walking speed (SWS), mean step length, cadence, 6-minute walking test (6MWT), Walking Index for SCI score, SCI Functional Ambulation Inventory gait score, American Spinal Injury Association Impairment Scale grade, neurological level, upper and lower extremity motor scores, modified Ashworth Scale, Penn Spasm Frequency Scale, and Spinal Cord Independence Measure version III were measured on admission, at the start of HWAT, at 2 and 4 weeks post-HWAT, and at discharge.
