Recently, wearable devices have been attracting significantly increased interest in human motion detection and physiological signal monitoring. Currently, it is still a great challenge to fabricate strain sensors with high performance good fit the body. In this work, we fabricated close-fitting graphene textile sensor based on without polymer encapsulation. Graphene oxide acts as colorant dye polyester fabric reduced at temperature, which endows excellent performance. Compared previously...
This paper is conducted to design, fabricate, and characterize a novel high-density large-scale ultrasonic transducer, which based on 64×4 array of 0.753 MHz piezoelectric micromachined transducer (pMUT) with 100 μm size 120 pitch. The fill factor the 69.4%, higher than other arrays in reports. Sol-gel method layer-by-layer annealing used fabricate isolated lead zirconate titanate elements into layer. membrane pMUT released by backside deep silicon etching. impedance-frequency spectrum 4 × 5...
HHT (Hereditary Haemorrhagic Telangiectasia or Rendu Osler Weber disease) is a known autosomal dominant dysplasia. The first clinical presentation of in child may be cerebral spinal AVM. We present the case young boy with who had previous cord AVF treated by surgical obliteration and then presented dural nine months later. This patient perimedullary subsequently developed new at different level. diagnosis was made MR imaging angiography.
Objective To evaluate the feasibility of axillary nerve (AN) visualization in healthy volunteers and diagnostic value AN injury via high‐resolution ultrasonography (HRUS). Methods was examined by HRUS on both sides 48 oriented transducer according to three anatomical landmarks: quadrilateral space, anterior subscapular muscle, posterior artery. The maximum short‐axis diameter (SD) cross‐sectional area (CSA) were measured at different levels, visibility graded using a five‐point scale....
To investigate the overall survival of patients with KRAS wild-type metastatic colorectal cancer (mCRC) after sequentially receiving both bevacizumab and cetuximab during course treatment.Twenty-six mCRC who received at Sun Yat-sen University Gastrointestinal Hospital were retrospectively analyzed. Group A (n = 8) comprised first, group B 18) those first. The objective response rate, progression-free survival, compared.Baseline characteristics between two groups statistically similar. in was...
Objective: To explore effective methods in diagnosing and treating cesarean scar pregnancy (CSP) after section. Materials Methods: The clinical data of 13 cases with CSP who were admitted to the present hospital from October 2009 February 2012 retrospectively analyzed. Results: agreement diagnostic rate was 92.3% (12/13). On basis transvaginal color Doppler ultrasonography 12 patients had medical therapy combined uterine artery embolization (UAE) curettage successfully performed. One patient...
Background and Objectives: Portal hypertension (PH), as the main consequence of cirrhosis, leads to development gastroesophageal varices (GEVs). Variceal hemorrhage (VH) caused by rupture GEVs is a life-threatening emergency. Thus, prediction VH risk considerably important. Our pilot study aimed identify factors variceal in cirrhosis. Materials Methods: Cirrhotic patients were prospectively included divided into two groups according presence or absence VH. Conventional ultrasound shear wave...
Rationale: We report our experience with 2 patients diagnosed grey zone lymphoma (GZL). The histopathological characteristics of lymphomatous tissues in these ranged between those diffuse large B-cell (DLBCL) and the classical Hodgkin lymphoma. Patient concerns: A 52-year-old female presented to hospital a history lower abdominal pain metastatic origin for days. She was acute appendicitis had undergone emergency surgery. 17-year-old male admitted because left upper abdomen pain. Diagnoses:...
Cesarean scar pregnancy (CSP) and uterine artery pseudoaneurysms (UAPs) are associated with massive hemorrhage mortality. As a result of their low prevalence, the occurrence CSP UAP in same patient is extremely rare. The authors describe who was initially misdiagnosed trophoblastic disease by ultrasonography. lesion had blood-rich area 75 × 65 61 mm on Pelvic angiography revealed right side uterus. underwent embolization (UAE) immediately after correct diagnosis confirmed. Curettage...
Ultrasound imaging is an effective method for noninvasive examination of both biological and non-biological structures. As the core parts ultrasound imaging, existing medical probes consist bulky piezoelectric ceramics. And development direction ultrasonic decrease in probe volume increase resolution. However, it hard conventional to follow this trend. In report, some novel micromachined transducer (pMUT) arrays nondestructive evaluation are introduced. PZT chosen as material due its high...
The fundamental issue of intra-body communication system design-body channel characteristics are studied in this work. frequency range body measurement is 100 Hz to 20 MHz which covers important low bands for baseband transmission. A signal generator and an oscilloscope used measure the characteristics, wideband transformers eliminate grounding interference. By analyzing results, proper determined.
In the design phase of network remote control system, due to lack sorting communication data, performance system is difficult stabilize at a higher level. Aiming this, and development optical fiber technology in are proposed. The MYC-J335X-V2 core board used as hardware with three-layer structure including use layer, storage layer service designed. Optical basis for data interaction all levels. Industrial DH/DH+ fieldbus repeater RT-FHI-S point established; sets fuzzy rules signals solve...
This prospective randomized controlled study was intended to assess the effects of different doses clopidogrel plus early rehabilitation therapy on motor function and inflammatory factors in patients with ischemic stroke. Between August 2018 October 2020, 90 cases stroke treated Second People’s Hospital Yibin were at a ratio 1 : receive either oral 50 mg/d (low-dose group) or 75 (high-dose group), 45 each group. The outcome measures including Barthel Index (BI), National Institutes Health...
Subspine impingement (SSI) does not have effective diagnostic criteria, especially in patients who also femoroacetabular (FAI). The classification of anterior inferior iliac spine (AIIS) morphology via three-dimensional CT is controversial. To propose a method for ultrasound-guided AIIS injection as way to diagnose SSI and evaluate the accuracy radiography methods, including 3-D MRI, well intraoperative findings. Patients diagnosed with FAI between September 2020 December 2021 were evaluated...
