We report a case of life-threatening esophageal hemorrhage after metal stent implantation successfully treated by arterial embolization. An 85-year-old woman was admitted in shock secondary to massive hematemesis and melena. Recent medical history revealed esophageal cancer treated 8 weeks previously by endoesophageal radiotherapy (40 Gy) and endoscopic placement of a covered Wall-stent prosthesis. Selective arteriography of the fifth posterior right intercostal artery showed massive contrast extravasation in the esophagus. Embolization was performed with 150-250-micron polyvinyl alcohol particles. Follow-up at 5 months was uneventful. Arteriography and embolization are advised when severe hemorrhage occurs after esophageal implantation of metal stents. 相似文献

2D molybdenum disulfide (MoS2) gives a new inspiration for the field of nanoelectronics, photovoltaics, and sensorics. However, the most common processing technology, e.g., liquid‐phase based scalable exfoliation used for device fabrication, leads to the number of shortcomings that impede their large area production and integration. Major challenges are associated with the small size and low concentration of MoS2 flakes, as well as insufficient control over their physical properties, e.g., internal heterogeneity of the metallic and semiconducting phases. Here it is demonstrated that large semiconducting MoS2 sheets (with dimensions up to 50 µm) can be obtained by a facile cathodic exfoliation approach in nonaqueous electrolyte. The synthetic process avoids surface oxidation thus preserving the MoS2 sheets with intact crystalline structure. It is further demonstrated at the proof‐of‐concept level, a solution‐processed large area (60 × 60 µm) flexible Ebola biosensor, based on a MoS2 thin film (6 µm thickness) fabricated via restacking of the multiple flakes on the polyimide substrate. The experimental results reveal a low detection limit (in femtomolar–picomolar range) of the fabricated sensor devices. The presented exfoliation method opens up new opportunities for fabrication of large arrays of multifunctional biomedical devices based on novel 2D materials. 相似文献

Incidence of prostate disease has seen a sudden boost over the last few years as a result of an increase in male life expectancy. Prostate carcinoma is the third most common cause of cancer mortality in Spain. Post-mortem studies reveal that this is the most prevalent neoplasia in the elderly. 30% of all males over 50 years could host malignant cells in their prostate, although only 20% of these neoplasias have clinical manifestations. Prostate carcinoma expansion occurs by local spreading, as well as lymph and blood dissemination. Local spreading to the urethra, bladder neck, trigonous and seminal vesicles is frequent. Lymph dissemination to obturating, hypogastric, iliac, presacral and paraaortic nodes is a major path for metastasis. Bone metastasis with increased acid phosphatase is the most illustrative sign of prostate adenocarcinoma expansion. Visceral metastasis occur more frequently in lungs, liver and renal glands. There is a 0.3% likelihood of skin metastasis from prostate adenocarcinoma. Considering the rareness of skin metastasis from prostate adenocarcinoma, the case reported in the present paper, first evidence of a prostate carcinoma, is even more exceptional. 相似文献

The Internet of Things era has promoted enormous research on sensors, communications, data fusion, and actuators. Among them, sensors are a prerequisite for acquiring the environmental information for delivering to an artificial data center to make decisions. The MXene-based sensors have aroused tremendous interest because of their extraordinary performances. In this review, the electrical, electronic, and optical properties of MXenes are first introduced. Next, the MXene-based sensors are discussed according to the sensing mechanisms such as electronic, electrochemical, and optical methods. Initially, biosensors are introduced based on chemiresistors and field-effect transistors. Besides, the wearable pressure sensor is demonstrated with piezoresistive devices. Third, the electrochemical methods include amperometry and electrochemiluminescence as examples. In addition, the optical approaches refer to surface plasmonic resonance and fluorescence resonance energy transfer. Moreover, the prospects are delivered of multimodal data fusion toward complicated human-like senses. Eventually, future opportunities for MXene research are conveyed in the new material discovery, structure design, and proof-of-concept devices. 相似文献
