To investigate the potential contribution of accessory respiratory muscle atrophy to decline forced vital capacity (FVC) in patients with SSc-associated interstitial lung disease (ILD).This single-centre, retrospective study enrolled 36 SSc-ILD who underwent serial pulmonary function tests and chest high-resolution CT (HRCT) simultaneously at an interval 1-3 years. The total extent ILD wall area level ninth thoracic vertebra on images were evaluated by two independent evaluators blinded...
ABSTRACT Objective To investigate clinical relevance of performing lung ultrasound (LUS) in patients with connective tissue disease (CTD)-associated interstitial (ILD) comparison high-resolution computed tomography (HRCT). Methods This single-centre study enrolled eligible CTD-ILD from the prospective LUS registry. Total B-lines were detected by assessment at 14 sites via LUS. Forced vital capacity, diffusing capacity for carbon monoxide (DLCO), DLCO/alveolar volume, 6-minute walking...
Self-aligned High Electron Mobility Transistor (HEMT) technology based on selectively doped GaAs/AlGaAs heterostructure for LSI circuits is presented. A unique epistructure, associated with gate dry recessing process which one of the most important technologies realizing E/D type HEMT DCFL described. Making best use refined recess technology, we have successfully fabricated and tested 4Kb SRAM, minimum address access time 2.0 ns at 77K. This highest speed ever reported RAMs.
The features of intralobar pulmonary sequestration vary on computed tomography (CT). Many cases demonstrate a mass or cystic lesion within lower lobe. We report herein case 55-year-old, female patient presenting with right back pain. Contrast enhanced (CE) CT revealed multiple, nodular, lesions suggesting recurrent infections surrounding focal emphysema. Three-dimensional (3D) reconstruction demonstrated sequestrated lung segment systemic, arterial blood supply. Based these findings, was...
Atypical type A thymomas exhibit more aggressive features than conventional thymomas. Type AB rarely have atypical components. We report a rare case of thymoma with an component, that was identified after pulmonary metastasectomy 11 years the primary surgery and long-term follow-up recurrence. 61-year-old female underwent extended thymectomy for anterior mediastinal tumor prior diagnosed (Masaoka stage II). Five ago, computed tomography showed well-circumscribed nodules up to 1.0 cm in both...
Spontaneous regression (SR) of thymoma is rare. A 44-year-old man with right chest pain underwent computed tomography (CT), which showed an 11.0 cm mass in the anterior mediastinum and pleural effusion. He refused surgery was sent home without medication additional treatment. One year later, had regressed to 5.5 cm, effusion disappeared. then lost follow-up. Four years after initial visit, he presented diplopia fatigue. significant increase his anti-acetylcholine receptor antibody levels led...
A 1-GHz high electron mobility transistor (HEMT) chip set for a cryogenic pseudorandom number generator subsystem that has enhancement/depletion (ED) direct-coupled FET logic (DCFL) circuits and operates at liquid nitrogen temperature is described. Using HEMT circuitry temperatures several advantages. The DC characteristics of the are improved. resistance interconnecting metal 77 K about one-third room temperature. This minimizes interconnection delay, which defined by RC time constant,...
胸腺に発生する腫瘍である脂肪線維腺腫は，WHO分類（第4版）において胸腺上皮性腫瘍の「その他の稀な胸腺腫」に分類されている良性腫瘍であるが，報告例が極めて少なく，その病態は明らかになっていない．今回，我々は脂肪線維腺腫の1切除例を経験したので報告する．
Metalorganic vapor phase epitaxy of InP with extremely low V/III ratios less than 10 was successfully carried out by using tertiarybutylphosphine, and detailed electrical optical properties were investigated for the first time. Featureless surface morphology obtained even a ratio as 3. Good properties, such carrier concentrations about 6×1014 cm−3 electron Hall mobilities more 30 000 cm2/V s measured at 77 K confirmed, although both Van der Pauw low-temperature photoluminescence results...
Progressive multifocal leukoencephalopathy (PML) is a rare opportunistic infection of the central nervous system caused by reactivation JC virus (JCV). Typical PML shows confluent, bilateral but asymmetric, subcortical lesions in supratentorial white matter on magnetic resonance imaging (MRI). We report here 50-year-old woman with systemic lupus erythematosus complicated lymphoma who developed atypical brain MRI findings limited to infratentorial area at presentation. She presented numbness...
Cholesterol granulomas of the thymus are extremely rare benign entities. Herein, we describe a case cholesterol granuloma in 45-year-old man who presented with multifocal anterior mediastinal lesions on computed tomography (CT). Positron emission (PET)–CT revealed increased fluorodeoxyglucose uptake, maximum standardized uptake value 8.3. Diffusion-weighted magnetic resonance imaging (MRI) extreme hypointensity. He underwent total thymectomy by median sternotomy for presumed multiple...
Spontaneous regression (SR) of thymoma is rare. We report a case surgically resected due to cystic changes owing acute ischemic infarction with an increased anti-acetylcholine receptor antibody level. A 61-year-old male underwent computed tomography (CT) scan, which showed 4.9 cm anterior mediastinal tumor and slight right pleural effusion. Blood test results indicated elevated white blood cell count 13300/mL. One month later, enhanced CT scan at our hospital spontaneous 3.7 no The contained...
Matrix-producing carcinoma (MPC) of the breast is an extremely rare subtype invasive cancer. MPC characterized by production a cartilaginous or osseous matrix without spindle cells. It aggressive carcinoma, often presenting as triple-negative frequently metastasizes to lungs; however, it rarely reoccurs solitary pulmonary metastasis. We report case 77-year-old non-smoking woman with metastasis MPC, which mimicked small cell lung cancer (SCLC). Initially, was misdiagnosed SCLC based on its...
Improvements in materials and process design technologies are discussed terms of realizing fully operational HEMT LSIs. Technology to guarantee highly uniform device parameters has been established. Cell stability investigated for variations characteristics. Fully 1Kb SRAMs have confirmed under marching tests partial galloping tests. The RAM chips also shown excellent uniformity access time. difference between maximum average values on the chip is 4%.
Impurity doping in InP layer grown by metalorganic vapor-phase epitaxy using tertiarybutylphosphine and organic sources is presented. Diethylzinc diethylselenide were used as the p-type n-type sources, respectively. Electrical properties surface morphology of impurity-doped layers together with their growth condition dependence investigated. Good controllability reproducibility level confirmed. The maximum levels 1.8×1018 1×1019 cm−3 successfully attained for p-InP n-InP, These results...
A spin cast process for producing polycrystalline silicon sheets low-cost and high-efficiency solar cells equipment its application to mass production are discussed.
