Adverse Events of Single Balloon Enteroscopy‐assisted Endoscopic Retrograde Cholangiopancreatography in the Elderly: A Propensity Score Matching Analysis

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Background Sedation for conventional endoscopic retrograde cholangiopancreatography (ERCP) has been reported to be safe even for elderly patients. However, the safety of sedation for balloon enteroscopy‐assisted ERCP (BE‐ERCP) has not been well‐studied in the elderly.

Brain-derived neurotrophic factor modulation in response to oxidative stress and corticosterone: role of scopolamine and mirtazapine

Life Sciences
Major Depressive Disorder (MDD) is a very complex disease, challenging to study and manage. The complexities of MDD require extensive research of its mechanisms to develop more effective therapeutic approaches. Crucial in the context of this disease is the role of brain-derived neurotrophic factor (BDNF) signaling pathway.This manuscript aims to ...

Inhibitory Effect of Lidocaine on Duodenal Peristalsis During Endoscopic Retrograde Cholangiopancreatography: A Multicenter, Randomized Controlled Trial (With Video)

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Conventional antispasmodics used during endoscopic retrograde cholangiopancreatography (ERCP), such as hyoscine butylbromide and glucagon, are often contraindicated in elderly patients with comorbidities. This trial aimed to assess the efficacy of lidocaine for inhibiting duodenal peristalsis during ERCP.

Efficacy and Safety of Remimazolam Compared to Midazolam for Sedation During Endoscopic Ultrasonography: A Single‐Center Retrospective Cohort Study

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Remimazolam is a novel ultra–short‐acting benzodiazepine that may offer advantages over conventional sedatives in endoscopic procedures. Evidence for its use in pancreatobiliary endoscopic ultrasonography (EUS) is limited. We compared the efficacy and safety of remimazolam and midazolam in outpatient pancreatobiliary EUS.

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

Mass Spectrometry Reviews, Volume 45, Issue 2, Page 392-428, March/April 2026.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry
