This paper synthesized a new type of ternary piezoelectric catalyst MoOx/ZnS/ZnO (MZZ) by a one-step method. The catalytic degradation of Rhodamine B (RhB) solution (10 µg/g, pH = 7.0) shows that the composite catalyst has excellent piezoelectric catalytic activity under ultrasonic vibration (40 kHz). The piezoelectric degradation rate of the optimal sample reached 0.054 min-1, which was about 2.5 times that of pure ZnO. X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman, transmission electron microscopy (TEM), scanning electron microscopy (SEM), and electrochemical impedance spectroscopy (EIS) technologies were used to analyze the structure, morphology, and interface charge transfer properties of the MZZ piezocatalysts. The results showed that the composite catalyst may have a core-shell structure. ZnS is coated on the surface of ZnO, while MoOx adheres to the surface of ZnS. This structure endowed MZZ larger specific surface area than ZnO, which benefits the RhB adsorption. More importantly, the formed heterojunction structure between ZnS and ZnO promotes the separation of positive and negative charges induced by the piezoelectric effect. MoOx species may act as a charge trap to further promote more carriers to participate in the reaction. In addition, MoOx may also be beneficial in adsorbing dyes. Active species capture experiments show that superoxide radicals and holes are the main active species in piezoelectric catalytic reactions on MZZ catalysts.
To investigate whether a previously performed endometrial ablation is associated with the development and diagnosis of endometrial cancer.

First, a systematic review was performed of the articles reporting the incidence of endometrial cancer in patients treated with endometrial ablation. Second, a systematic review was performed to identify all individual cases of endometrial cancer after ablation to evaluate presenting symptoms, diagnostic work-up, potential risk factors, and the type and stage of the endometrial cancer. A systematic search was performed, using Medline, EMBASE, and the Cochrane Library databases, from inception through February 24, 2022.

Based on 11 included studies, the incidence of endometrial cancer in a population of 29 102 patients with a prior endometrial ablation ranged from 0.0% to 1.6%.A total of 38 cases of endometrial cancer after ablation were identified. In 71% of cases (17 of 24 cases), vaginal bleeding was the first presenting symptom. E-616452 With transvaginal ultrasound it was possible to identify and measure the endometrial thickness in eight cases. Endometrium sampling was successful in 16 of 18 described cases (89%). In 18 of 20 cases (90%) pathologic examination showed early-stage endometrioid adenocarcinoma (International Federation of Gynecology and Obstetrics stage I).

Previous endometrial ablation is not associated with the development of endometrial cancer. Diagnostic work-up is not impeded by previous endometrial ablation. In addition, endometrial cancers after endometrial ablation are not detected at an advanced stage.

The objective of this research was to determine the abrasive and remineralising efficacy of quail eggshell (Coturnix coturnix) incorporated into a new experimental toothpaste.

An experimental study was designed to compare the surface microhardness of the dental enamel of bovine lateral incisors exposed to different toothpastes. In relation to microroughness (abrasive efficiency), the unit of analysis was each specimen with 16 polymethylmethacrylate (PMMA) blocks. For the remineralisation variable, the unit of analysis was each bovine lateral incisor tooth. A sample size of 16 was determined for each group.

The unpolished PMMA specimens presented the highest mean surface microroughness with a mean of 4.60 ± 1.47 µm, whilst the quail paste, universal polishing paste, control paste, and Diamond Excel Paste showed a mean of 1.16 ± 0.40 µm, 0.63 ± 024 µm, 0.45 ± 0.22 µm, and 0.43 ± 0.17 µm, respectively, presenting significant differences (P < .001). When comparing the surface microhardness of bovine latee.Lead halide perovskite materials, such as MAPbBr3 and MAPbI3, show excellent semiconductor properties, and thus, they have attracted a lot of attention for applications in solar cells, photodetectors, etc. Here, a periodic strain can dynamically manipulate the build-in electric field (Ebi) of the depletion region with piezoelectricity at the Au/MAPbBr3 interface. As a result, the photovoltaic short-circuit current density (Jsc) and the open-circuit voltage (Voc) are increased by 670 and 82%, respectively, by applying an external strain upon an asymmetric solar-cell-like Au/MAPbBr3/Ga structure. Furthermore, the equivalent piezoelectric d33 values of ∼3.5 pC/N are confirmed in the Au/MAPbBr3/Au structure with both the sinusoidal strain and the 405 nm light illumination with 220 mW/cm2 upon one semitransparent Au electrode. This study not only proves that pressure can effectively enhance the energy conversion efficiency of the halide perovskite-based solar cells and light detectors but also supposes a multifunctional sensor, which can detect light intensity, sense dynamic pressure, explore accelerated speed, etc. simultaneously.Third space endoscopy or submucosal endoscopy using a mucosal flap valve allows secure access to the submucosal and deeper layers of the gastrointestinal tract without the risk of a full-thickness perforation. This allows the performance of submucosal tunneling and myotomy for spastic segments of the gastrointestinal tract. Per oral endoscopic myotomy (POEM) has been described for the treatment of achalasia cardia and other spastic esophageal disorders and is widely implemented. Endoscopic pyloromyotomy (G-POEM) has been performed for the treatment of refractory gastroparesis. Z-POEM for Zenker's diverticulum, D-POEM for epiphrenic diverticulum, and per-rectal endoscopic myotomy for treatment of Hirschsprung's disease are described..Multimodal assessment of colorectal polyps is needed before decision-making for endoscopic mucosal resection or endoscopic submucosal dissection (ESD). Assessment should include morphology according to Paris classification, magnification endoscopy for vascular pattern, and Kudo pit pattern analysis. ESD should be offered to patients that have Vi pit pattern, lateral spreading tumors (LST) granular multinodular and LST nongranular, lesions with fibrosis and those in patients with inflammatory bowel disease. A defined strategy for resection and planning is crucial for successful and efficient resection with a clear audit of outcomes aiming for a perforation and bleeding rate of less than 1% and R0 resection greater than 90%.Endoscopic submucosal dissection (ESD) is the preferred strategy for the resection of large superficial neoplasia throughout the gastrointestinal tract in Asian countries. The transition of ESD to the West has been slower because of various regional and training differences. Nonetheless, over the past couple of decades, the steady growth of ESD mentors in the West and the introduction of viable training pathways and dedicated devices and accessories have led to the increasing adoption of ESD and other third space endoscopic procedures.Gastric endoscopic submucosal dissection (ESD) is established for management of early gastric cancer (EGC). Diagnosis of EGC relies on adequate endoscopic assessment involving lesion size, histopathology, presence of ulceration, and depth of invasion. Absolute indications for endoscopic resection of EGC are if patients are presumed to have a less than 1% risk of lymph node metasta endoscopic submucosal dissectionsis, and long-term outcomes are similar to those with surgical gastrectomy. Duodenal ESD is more technically difficult and requires expertise in ESD in other locations.Endoscopic submucosal dissection (ESD) is well-accepted endoscopic resection modality for esophageal lesions with benefits in certain situations. ESD offers potential cure for early esophageal cancer and detailed pathologic information for risk stratification. Techniques are mostly standardized, and the use of traction method is encouraged. Indication and proper techniques of ESD in esophageal disease and clinical outcomes will be discussed in this article with pearls for care planning and management during periprocedural period.Endoscopic submucosal dissection (ESD) training in Japan is pursued through a designated master-apprentice, organ-based stepwise training model. However, applying a similar program to the United States is not a practical strategy due to the significant differences in the training system and disease prevalence. To incorporate the ESD training into the current advanced endoscopy fellowship program, the use of recently developed techniques and technologies to improve the efficiency of ESD is ideal. The ESD training program in the United States should be prevalence-based, with increased involvement of trainees depending on their objectively assessed competency levels.Electrosurgery is the application of high-frequency electrical alternating current to biologic tissue to cut, coagulate, desiccate, and/or fulgurate. Electrosurgery is commonly used in gastrointestinal endoscopy, with applications including biliary sphincterotomy, polypectomy, hemostasis, the ablation of lesions, and endoscopic surgery. Understanding electrosurgical principles is important in endoscopic surgery to achieve the desired therapeutic effect, optimize procedural outcomes, and minimize risks or adverse events. This article describes fundamental principles that apply to electrosurgical units, operator technique, and practical considerations for achieving desired tissue effects in endoscopic surgery; and provides practical guidance and safety considerations when using electrosurgical units in endoscopic surgery.Endoscopic resection has been widely applied especially in endoscopic submucosal dissection and third space endoscopy (TSE). Flexible endoluminal robotics allow performance of endoscopic submucosal dissection with exposure of the submucosal plane for precise dissection using two robotic arms. The introduction of TSE revolutionized the horizon of therapeutic endoscopy to the submucosal space beneath and beyond the mucosa. Advantages of TSE include avoidance of full thickness incision in gastrointestinal tract through the submucosal tunneling for performance of peroral endoscopic myotomy and submucosal tunneling endoscopic resection. In future, robotic-driven devices should be developed to enhance performance of complex endoluminal procedures and TSE.The risk-benefit profile of submucosal endoscopic procedures is generally favorable but there exist unique considerations regarding the recognition, treatment, and prevention of submucosal endoscopic complications. Bleeding during the procedure can be managed with knife electrocautery, tamponade by injection of additional submucosal agent, or hemostatic forceps, depending on the location and degree of bleeding. Delayed bleeding should be managed with repeat endoscopy. Potential means to reduce the risk of delayed bleeding include anticipatory coagulation of visible vessels in the dissection ulcer base, applied hemostatic chemicals, snares, clips, and sheets of cultured cells.
