Metal oxides are promising (photo)electrocatalysts for sustainable energy technologies due to their good activity and abundant resources. Their applications such as photocatalytic water splitting predominantly involve aqueous interfaces under electrochemical conditions, but probing oxide-water interfaces is proven to be extremely challenging. Here, we present an electrochemical scanning tunneling microscopy (EC-STM) study on the rutile TiO(110)-water interface, and by tuning surface redox chemistry with careful potential control we are able to obtain high quality images of interfacial structures with atomic details.

In the process of making mushrooms into vacuum-fried crisps, the resulting blanched broth (BB) and centrifuged broth (CB) are often discarded, thereby increasing the amount of wastewater and treatment costs. This study measured the proximate compositions, bioactive components, taste components, and minerals of freeze-dried BB and CB and then used functional indigestible dextrin (Fibersol-2) as a carrier to make these two broths into instant drinks. The solids of the BB and CB contained protein (16.

Article Synopsis
  • Some data in a recent scientific paper looked very similar to data from another published paper by different researchers.
  • Because of this, the editor decided to retract (take back) the paper so it wouldn't be used anymore.
  • The authors didn't respond to the editor's request for an explanation, and the editor apologized to readers for any confusion.

Ni-based transition metal oxides are promising oxygen-evolution reaction (OER) catalysts due to their abundance and high activity. Identification and manipulation of the chemical properties of the real active phase on the catalyst surface is crucial to improve the reaction kinetics and efficiency of the OER. Herein, we used electrochemical-scanning tunnelling microscopy (EC-STM) to directly observe structural dynamics during the OER on LaNiO (LNO) epitaxial thin films.

Article Synopsis
  • Elastography ultrasound (EUS) is an important imaging method, but it faces challenges like subjective interpretation and hardware limitations that affect the miniaturization of equipment.
  • A new deep neural network has been developed to create virtual EUS (V-EUS) from traditional B-mode images, providing a cost-effective solution.
  • Analysis of 4580 breast tumor cases shows that V-EUS performs similarly to real EUS in identifying tumors, and it improves the diagnostic accuracy of portable ultrasound devices by approximately 5%.

Extractions of the underground parts of valerian were prepared with water and ethanol (25-95%) at 25-75 °C. Extraction yields, bioactive compounds, and the 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging ability of lyophilized extracts were determined. The inhibitory effects of the extracts, valerenic acid derivatives and phenolic acids, on metabolic syndrome (MS)-related enzymes activities were further examined.

Objective: The growth of oviduct mucosa in the uterine cavity was observed by co-culture of oviduct mucosa cells and endometrial cells in different proportions to study the possibility and function of the growth of oviduct mucosa in the uterine cavity.

Methods: The extracted cells were identified by immunofluorescence with cytokeratins 19 (CK19) and vimentin. A Cell Counting Kit-8 (CCK8) experiment, cell decidualization induction, and HE staining were performed after the co-culture of two kinds of cells in different proportions.

Objective: This study retrospectively reviewed 46 cases of gastric gastrointestinal stromal tumors treated by endoluminal endoscopic full-thickness resection (EFR) microsurgery in our gastrointestinal endoscopy center. We aimed to evaluate the EFR for the treatment of gastric gastrointestinal stromal tumors originating from the muscularis propria.

Methods: A total of 46 patients with gastric gastrointestinal stromal tumors originated from the muscularis propria layer from January 2012 to June 2015 were treated with EFR.

Background: The diagnosis and treatment of small-bowel diseases is clinically difficult. The purpose of this study was to evaluate the diagnostic and therapeutic value of double-balloon enteroscopy in small-bowel diseases.

Methods: The history and outcomes of 2806 patients who underwent double-balloon enteroscopy from July 2004 to April 2017 were reviewed, which included 562 patients with obscure digestive tract bleeding, 457 patients with obscure diarrhea, 930 patients with obscure abdominal pain, 795 patients with obscure weight loss, and 62 patients with obscure intestinal obstruction.

Article Synopsis
  • Pancreatic cancer is a really tough disease and is one of the leading causes of cancer-related deaths.
  • In a study, scientists found that a molecule called miR-29b is less common in pancreatic cancer tissues, while another molecule, DNMT3b, is more active.
  • They discovered that miR-29b can help stop cancer cells from growing by targeting DNMT3b, suggesting miR-29b could be important for new treatments for pancreatic cancer.

  • The study looks at how certain cells from rats (called activated hepatic stellate cells) affect other immune cells (Th1 and Th2) when they grow together in a lab.
  • When the Th1 cells (which help fight infections) were grown with the hepatic stellate cells for 48 hours, there were fewer of them and their ability to fight was weakened, while the Th2 cells (which can help with allergies) didn't change much.
  • The researchers also found that some proteins in the hepatic stellate cells changed after growing with the Th1 and Th2 cells, which might help explain why the Th1 cells didn't do as well.

Background: Gastric stromal tumors arising from the muscularis propria are located in deeper layers. Endoscopic resection may be contraindicated due to the possibility of perforation. These tumors are therefore usually removed by surgical or laparoscopic procedures.

The small intestine is approximately 5-6 m long and occupies a large area in the abdominal cavity. These factors preclude the use of ordinary endoscopy and X-ray to thoroughly examine the small intestine for bleeding of vascular malformations. Thus, the diagnosis of intestinal bleeding is very difficult.

Aim: To evaluate the efficacy, safety and feasibility of endoscopic full-thickness resection (EFR) for the treatment of gastric submucosal tumors (SMTs) arising from the muscularis propria.

Methods: A total of 35 gastric SMTs arising from the muscularis propria layer were resected by EFR between January 2010 and September 2013. EFR consists of five major steps: injecting normal saline into the submucosa; pre-cutting the mucosal and submucosal layers around the lesion; making a circumferential incision as deep as the muscularis propria around the lesion using endoscopic submucosal dissection and an incision into the serosal layer around the lesion with a Hook knife; a full-thickness resection of the tumor, including the serosal layer with a Hook or IT knife; and closing the gastric wall with metallic clips.

Background: Gastric stromal tumors are the most common type of tumor originating from mesenchymal tissue. The traditional method for the treatment of gastric stromal tumor is surgical operation or therapeutic laparoscopy. More recently, endoscopic micro-traumatic surgery has become possible for gastric stromal tumors, with any perforation caused by endoscopic therapy mended endoscopically.
