Dynamic Optical Encryption Fueled via Tunable Mechanical Composite Micrograting Systems.

Optical grating devices based on micro/nanostructured functional surfaces are widely employed to precisely manipulate light propagation, which is significant for information technologies, optical data storage, and light sensors. However, the parameters of rigid periodic structures are difficult to tune after manufacturing, which seriously limits their capacity for in situ light manipulation. Here, a novel anti-eavesdropping, anti-damage, and anti-tamper dynamic optical encryption strategy are reported via tunable mechanical composite wrinkle micrograting encryption systems (MCWGES).

Historical Review of Acute Pancreatitis Research Over the Last 80 Years.

Objectives: Research on acute pancreatitis (AP) has been ongoing for a long time. It is necessary to summarize and investigate the history of AP research.

Methods: Publications related to AP research were retrieved from PubMed.

Nintedanib Alleviates Chronic Pancreatitis by Inhibiting the Activation of Pancreatic Stellate Cells via the JAK/STAT3 and ERK1/2 Pathways.

Background: Nintedanib (Ninte) has been approved for the treatment of pulmonary fibrosis, and whether it can ameliorate chronic pancreatitis (CP) is unknown.

Aims: This study was conducted to investigate the effect and molecular mechanism of Ninte on pancreatic fibrosis and inflammation in vivo and in vitro.

Methods: The caerulein-induced CP model of murine was applied, and Ninte was orally administered.

Clip-assisted endoloop ligation of the mucosal defect after resection of colorectal polyps decreased postprocedural delayed bleeding.

Background: Postprocedural delayed bleeding (PDB) remains the most common major complication of colorectal polypectomy. Incomplete clip closure of mucosal defect and unclosed injured blood vessels in gaps between clips may be the risk factors for PDB.

Objectives: To observe whether completely no-gap closure of mucosal defect after polypectomy can reduce PDB occurrence.

Global status of acute pancreatitis research in the last 20 years: A bibliometric study.

Acute pancreatitis (AP) is a common digestive disease encountered in Emergency Departments that carries a heavy socioeconomic burden. This study was conducted to determine the global status of AP research. Articles related to AP published in 1999 to 2018 were retrieved from the Web of Science (WOS) database and the 20 highest-output countries or regions were determined based on the total number of publications.

Clinical characteristics of smoking-related chronic pancreatitis.

Objective: The pathogenesis of chronic pancreatitis (CP) is not completely clear. With further studies, smoking is toxic to the pancreas. This study classified smoking-related CP as a new etiology of CP and defined the cutoff of smoking.

Risk factor analysis and nomogram development for steatorrhea in idiopathic chronic pancreatitis.

Objectives: Steatorrhea, a sign of severe pancreatic exocrine insufficiency (PEI), is related to consequences caused by pancreatitis. This study aimed to identify predictors and to construct a nomogram for steatorrhea in idiopathic chronic pancreatitis (ICP).

Methods: ICP patients admitted to our hospital from January 2000 to December 2013 were enrolled in this retrospective-prospective cohort study and randomly assigned to the training and validation cohorts.

Success and Safety of Needle Knife Papillotomy and Fistulotomy Based on Papillary Anatomy: A Prospective Controlled Trial.

Background: Needle knife papillotomy (NKP) and fistulotomy (NKF) are the two most commonly used rescue techniques for patients with difficult biliary cannulation (DBC). Anatomy of the major duodenal papillae (MDP) influences the optimal precut technique for biliary access. However, comparative studies of the success and safety of NKP and NKF based on the anatomy of MDP have been scarce.
