In order to predict the probability of collapse a femoral head in which there is avascular necrosis, we used magnetic resonance imaging evaluate sixty-six hips (fifty patients) necrosis was early stages and not yet visible. The were followed radiographically for an average forty-nine months (range, sixteen eighty-four months), with forty-four twelve seventy-three months). Twenty-one (32 per cent) heads had collapsed by thirty-two months. Of twenty-three involved at least one-fourth diameter...
We performed a prospective study using MRI to evaluate early necrosis of the femoral head in 48 patients receiving high-dose corticosteroids for treatment various autoimmune-related disorders. The mean interval from initiation corticosteroid therapy first examination was 2 months (0.5 6). repeated, and period follow-up 31 (24 69). Abnormalities were found on hips (32%). initial changes showed well-demarcated, band-like zones which seen at 3.6 after with steroids. In 14 these (45%) there...
Evolution with thickness of the structure polycrystalline silicon (poly-Si) films prepared at 300 °C has been studied by plasma decomposition SiF4/SiH4/H2 source gases. The poly-Si varied are characterized mainly Raman spectroscopy, x-ray diffraction (XRD), and supplementarily reflection high-energy electron diffraction, transmission microscopy, Fourier-transform infrared (FT-IR) electron-spin resonance (ESR), secondary-ion-mass spectroscopy (SIMS) measurements. crystalline fraction film was...
[Purpose] The present study longitudinally investigated injury occurrences and the risk factors for muscle tightness, core stability, dynamic standing balance among junior high school student baseball players. [Subjects] Thirty-nine male students, belonging to clubs at 2 schools, participated in this study. [Methods] Study measurements were obtained twice, once early stage of season (March) end (July). All subjects underwent tightness testing, Star Excursion Balance Test (SEBT), trunk...
The purpose of this study was to clarify whether bone marrow edema is detectable on initial MR imaging steroid-induced osteonecrosis the femoral head.Forty-eight hips with were examined consecutively and radiography. In a previously reported screening program, diagnosed when subchondral bands abnormal signals present. images 200 100 patients receiving high-dose steroid therapy prospectively. Subchondral detected in 48 at mean 14 weeks after initiation therapy.On follow-up 47 (one hip...
To assess the efficacy of quantitative (1)H MR spectroscopy (MRS) using external standard method to predict pathological response neoadjuvant chemotherapy with an anthracycline-based regimen in breast cancer patients.Sixteen patients were included. Tumor was evaluated after second cycle MRI and MRS. Final histopathology following surgery four cycles served as reference.The average normalized choline (Cho) signal 1.2 (range, 0.40 2.8). There no significant differences baseline tumor size Cho...
[Purpose] The purpose of this study was to examine the relationship between lower extremity tightness and balance, measured by Star Excursion Balance Test (SEBT), in junior high school baseball players. [Subjects] Thirty-three male students belonging clubs 2 schools participated study. [Methods] For SEBT, we chose anterior (ANT), posterior (POS), lateral (LAT), medial (MED) directions. Regarding muscle measurement, angle each joint bilateral iliopsoas, quadriceps, hamstring, gastrocnemius,...
Despite proposals and guidelines to prevent baseball injuries in young players by societies organizations, many shoulder elbow continue occur among junior high school players. In order investigate the training conditions of risk factors for pain players, we conducted a questionnaire survey throughout country.The was September 2016.A total 11,134 belonging 495 teams responded survey. Among these, 4004 trained every day week 1151 played games month with no off-season. 9752 who did not have...
<ns3:p>Oral contraceptive use, vaccination for Coronavirus disease 2019 (COVID-19), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are risk factors venous thromboembolism. Branch retinal vein occlusion (BRVO) generally develops mid-60s patients. Herein, we present a case of superotemporal BRVO caused by the above mentioned in young woman. To best our knowledge, this is first report about associated with oral contraceptives, COVID-19 vaccination, SARS-CoV-2. A...

Plasma etching of ITO (In 2 O 3 :Sn indium tin oxide) thin films has been performed using a CH 4 /H plasma. Etching occurs above substrate temperature ( T s ) 60°C and the etch rate increases with increasing , while amorphous like or polymer-like carbon deposits onto below 60°C. The apparent activation energy is 4.12 kcal/mol (0.18 eV). This small suggests that desorption produced volatiles rate-limiting process. Fine patterns (1.5 µmL/S) were obtained this gas mixture.
Abstract Purpose To assess the efficacy of 1 H MR spectroscopy (MRS) to evaluate early responses neoadjuvant chemotherapy in breast cancer patients, as compared that standardized uptake value (SUV) 18 F‐fluorodeoxyglucose (FDG) positron emission tomography (PET). Materials and Methods This retrospective study included seven patients with who had both single‐voxel MRS PET/computed (CT) acquired before, during, after chemotherapy. Results The averages Choline (Cho) integral peak SUV before...
[Purpose] The purpose of this study was to clarify the intrinsic factors influencing deep squatting posture and investigate utility ankle joint dorsiflexion measurement using posture. [Subjects] subjects were 71 healthy male individuals. [Methods] asked squatted with their heels down then divided into 2 groups: possible impossible squatting. anthropometric characteristics assessed, flexibility movement range lower extremities tested. To identify posture, a dediscriminant analysis performed...
[Purpose] We examined and clarified the relationship between maximum squat depth range of motion ankle, knee, hip joints, knee muscle strength. [Participants Methods] Nine healthy males participated in this study performed a deep with upper extremities raised; movement was analyzed by two-dimensional analysis. measured ankle dorsiflexion, flexion, flexion ranges motion, as well extension strengths squatting strength each joint. [Results] The right dorsiflexion significant predictor angle on...
Background: Parotid gland metastasis in breast cancer is extremely rare, and only 14 cases have been reported between 1982 2010. Case Report: A 67-year-old female patient was diagnosed with invasive lobular carcinoma of the left breast. Although clinical staging T1N3M1 (stage IV), tumor experienced a complete response to chemotherapy. We therefore performed mastectomy followed by radiotherapy, continued administration trastuzumab. However, 11 months later, complained swelling parotid gland....
[Purpose] The purpose of this study was to determine the effect various hand position widths during push-up plus (PUP) exercise on activity scapular stabilizing muscles and other upper-extremity involved in exercise. [Subjects Methods] Nine healthy men participated our study. PUP performed a stable surface seven different positions, namely shoulder width (SW), narrower SW (NSW) wider (WSW) at 10%, 20%, 30%. Surface electromyography used measure muscle activities ratio upper trapezius (UT),...
