Electrochromic capacitors, which are capable of altering their appearances in line with their charged states, are drawing substantial attention from both academia and industry. Tungsten oxide is usually used as an electrochromic layer material for electrochromic devices, or as an active material for high-performance capacitor electrodes. Despite this, acceptable visual aesthetics in electrochromic capacitors have almost never been achieved using tungsten oxide, because, in its pure form, this compound only displays a onefold color modulation from transparent to blue.

Background And Aims: Evaluation of deep remission in Crohn's disease (CD) can be challenging when the disease is confined to the small intestine. The aim of this study was to evaluate the effectiveness of through-the-scope EUS during double-balloon enteroscopy (DBE-EUS) in distinguishing small-bowel CD patients in endoscopic remission from those with active disease.

Methods: Patients who underwent DBE-EUS were divided into groups of endoscopic remission and endoscopic activity according to segmental Simple Endoscopic Score for Crohn's Disease (SES-CD).

Article Synopsis
  • Pancreatic stenting is effective in reducing the occurrence and severity of post-ERCP pancreatitis (PEP), but optimal timing for placement is not well studied.
  • A study analyzed 590 patients to compare early pancreatic stent placement (EPSP) with late placement (LPSP), finding that EPSP significantly lowers PEP rates (2.9% vs. 7.3%) and hyperamylasemia (19.7% vs. 27.8%).
  • Results support the practice of placing pancreatic stents immediately before or after endoscopic procedures to minimize pancreatitis risk.

Carriage of HLA-DQA1*05 is thought to increase the formation of anti-tumour necrosis factor alpha (TNF-α) antibodies, reducing the drug efficacy in Crohn's disease (CD) patients. However, little data are currently available for small-bowel Crohn's disease (SB-CD). A specific assessment of the impact of HLA-DQA1*05 on the clinical response to treatment with infliximab (IFX), a TNF-α antagonists, in SB-CD patients is necessary.

Ferroptosis, a recently discovered form of regulated cell death, has been implicated in the development of ulcerative colitis (UC). While Piezo1's role in inducing ferroptosis in chondrocytes and pulmonary endothelial cells is documented, its regulatory function in ferroptosis and intestinal epithelial cells in UC remains unclear. To address this, colonic tissue samples from patients with UC were examined, and specific intestinal epithelial Piezo1-deficient (Piezo1) mice were created to investigate Piezo1's role in UC pathogenesis.

Article Synopsis
  • A study evaluated whether rectal indomethacin provides any additional benefits in preventing pancreatitis during ERCP for patients already receiving pancreatic stenting.
  • In a cohort of 607 high-risk patients, no significant differences were found in the incidence of post-ERCP pancreatitis or related complications between those who received indomethacin and those who didn’t.
  • The findings suggest that adding rectal indomethacin to the standard prophylactic pancreatic stenting is unnecessary, as it did not improve outcomes for these patients.

  • Ulcerative colitis (UC) is a chronic condition whose exact causes are not fully understood, but this study investigates the role of ferroptosis in its development by identifying key genes associated with both UC and ferroptosis.* -
  • The researchers analyzed gene expression data and discovered six key genes related to ferroptosis in UC, narrowing it down to three (HIF1A, SLC7A11, and LPIN1) that showed strong potential for diagnosis through logistic regression and ROC curve analysis.* -
  • The findings suggest that these hub genes have significant implications for understanding the mechanisms of UC and could lead to new diagnostic and therapeutic strategies.*

  • In 2023, the Omicron variant of SARS-CoV-2 led to a significant outbreak of COVID-19 in China, raising concerns about its impact on patients with inflammatory bowel disease (IBD).
  • This study analyzed data from 534 IBD patients, finding that 34.3% experienced worsening symptoms after COVID-19, particularly linked to being male, having a lower body mass index (BMI), and stopping medication.
  • The research underscores that while IBD patients had a similar COVID-19 infection rate as the general population, specific factors like male sex, BMI decline, and medication cessation significantly increased the risk of IBD symptom exacerbation.

Background: When unintentional pancreatic duct access occurs during difficult biliary cannulation, the double guidewire (DGW) or transpancreatic sphincterotomy (TPS) may be utilized. DGW can be easily switched to TPS due to the existing guidewire in the pancreatic duct. However, the efficacy of TPS after DGW, named sequential DGW-TPS technique, versus primary TPS has not been assessed.

Epithelial barrier dysfunction and crypt destruction are hallmarks of inflammatory bowel disease (IBD). Intestinal stem cells (ISCs) residing in the crypts play a crucial role in the continuous self-renewal and rapid recovery of intestinal epithelial cells (IECs). However, how ISCs are dysregulated in IBD remains poorly understood.

Bainong sterility (BNS) is a thermo-sensitive genic male sterile wheat line, characterised by anther fertility transformation in response to low temperature (LT) stress during meiosis, the failure of vacuole decomposition and the absence of starch accumulation in sterile bicellular pollen. Our study demonstrates that the late microspore (LM) stage marks the transition from the anther growth to anther maturation phase, characterised by the changes in anther structure, carbohydrate metabolism and the main transport pathway of sucrose (Suc). Fructan is a main storage polysaccharide in wheat anther, and its synthesis and remobilisation are crucial for anther development.
