Transcutaneous partial pressure of carbon dioxide monitoring during EUS-guided drainage of peripancreatic fluid collections using carbon dioxide insufflation: A prospective study.

Background: Carbon dioxide (CO) insufflation has become more commonly used in EUS-guided interventions in recent years. However, there is a paucity of information regarding methods by which to monitor in vivo CO levels. This study aimed to assess the feasibility of a novel noninvasive method to monitor transcutaneous partial pressure of CO [INSIDE:1] levels during EUS-guided drainage of peripancreatic fluid collections (PFCs).

Changes in tumor vascularity depicted by contrast-enhanced EUS as a predictor of prognosis and treatment efficacy in patients with unresectable pancreatic cancer (PEACE): A study protocol.

Patients with unresectable pancreatic cancer have a poor prognosis. The analysis of prognostic factors before treatment may be helpful in determining the best therapeutic strategies. The aim of the PEACE study is to assess the vascularity of pancreatic malignant tumors using contrast-enhanced harmonic EUS (CEH-EUS) and to clarify the prognostic value of tumor vascularity in patients with locally advanced and metastatic pancreatic cancer.

Endoscopic resection of the pancreatic tail and subsequent wound healing mechanisms in a porcine model.

Background: Laparoscopic resection of the pancreatic body and tail is the predominant methodology to remove lesions in these locations; its safety and surgical planning are relatively mature, but it remains a complex and high-precision surgical operation, requiring abundant experience and skills in laparoscopic surgery, with a 10% rate of complications.

Aim: To verify the feasibility and safety, as well as to examine the complications of endoscopic pancreatectomy and healing mechanisms of pancreatic wounds after endoscopic resection.

Methods: Transgastric endoscopic resections of varying sizes of pancreases were performed in 15 healthy Bama miniature pigs.

Multivariate analysis of the factors affecting the prognosis of walled-off pancreatic necrosis after endoscopic ultrasound-guided drainage.

Background And Aims: Endoscopic ultrasound (EUS)-guided drainage has become the treatment of choice for walled-off pancreatic necrosis (WOPN). However, no consensus exists on the most significant patient- and procedure-related factors that affect prognosis. The aim of the study is to investigate the correlation between patient- and procedure-related factors and post-procedure complications after EUS-guided drainage.

Long-term assessment of over-the-scope clip (OTSC) behavior after gastric application.

The aim of this study was to assess the long-term behavior of the over-the-scope clip (OTSC) after gastric application. A database of all patients who had OTSC placement with regular follow-up at a tertiary hospital between November 2013 and September 2016 was retrospectively analyzed. The incidence, time, and related adverse events of clip attachment and detachment were recorded.

The cross-lagged relationship between interpersonal forgiveness and depression symptoms in China.

This study investigated the relationship between the process of forgiveness and depressive symptoms in China. A total of 116 college students who had experienced an interpersonal transgression "within the past week" were selected to perform the tracking measurements at 2-week intervals. Cross-lagged models showed that the victim's depressive symptoms were related to increasing revenge and avoidance motivations as well as decreased benevolence motivation; however, the revenge, avoidance, and benevolence motivations of the victims did not predict subsequent changes in depressive symptoms.

Syntheses of water-soluble acyclic naphthalene oligomers and their applications in water.

Water-soluble -CH2- bridged acyclic naphthalene oligomers (WN2 and WN3) were designed and prepared successfully. Interestingly, WN3 can be used in reversible dispersion of carbon nanotubes in water by changing the pH efficiently.

Consensus on the digestive endoscopic tunnel technique.

With the digestive endoscopic tunnel technique (DETT), many diseases that previously would have been treated by surgery are now endoscopically curable by establishing a submucosal tunnel between the mucosa and muscularis propria (MP). Through the tunnel, endoscopic diagnosis or treatment is performed for lesions in the mucosa, in the MP, and even outside the gastrointestinal (GI) tract. At present, the tunnel technique application range covers the following: (1) Treatment of lesions originating from the mucosal layer, .

A multi-institution consensus on how to perform EUS-guided biliary drainage for malignant biliary obstruction.

Background And Objectives: EUS-guided biliary drainage (EUS-BD) was shown to be useful for malignant biliary obstruction (MBO). However, there is lack of consensus on how EUS-BD should be performed.

Methods: This was a worldwide multi-institutional survey among members of the International Society of EUS conducted in February 2018.

A new amphiphilic pillar[5]arene: synthesis and controllable self-assembly in water and application in white-light-emitting systems.

A new amphiphilic pillar[5]arene with excellent surface activity was designed and synthesized successfully for the first time. Interestingly, this pillar[5]arene shows controllable self-assembly behaviour in water and can be applied in white-light-emitting systems.

Reversible surface activity and self-assembly behavior and transformation of amphiphilic ionic liquids in water induced by a pillar[5]arene-based host-guest interaction.

In this paper, we aimed to develop a reversible and effective method to control the surface activity and self-assembled morphology of amphiphilic imidazolium-type ionic liquids (G) in water. For this purpose, a series of pillar[5]arene/imidazolium supramolecular complexes were designed and prepared. Before the formation of the host-guest complex, the surface activity of G7 worked well, and foams could be generated easily.

Heterochromatin and RNAi regulate centromeres by protecting CENP-A from ubiquitin-mediated degradation.

Centromere is a specialized chromatin domain that plays a vital role in chromosome segregation. In most eukaryotes, centromere is surrounded by the epigenetically distinct heterochromatin domain. Heterochromatin has been shown to contribute to centromere function, but the precise role of heterochromatin in centromere specification remains elusive.

Retrievable puncture anchor traction method for EUS-guided gallbladder drainage: a porcine study.

Background And Aims: EUS-guided gallbladder drainage (EUS-GBD) is a challenging technique for endoscopists that requires a high level of skill. EUS-GBD is challenging because the gallbladder can be easily collapsed. To resolve this issue, we aimed to develop a retrievable puncture anchor traction (RPAT) method for EUS-GBD.

Evaluation of Gastric Emptying by Transabdominal Ultrasound after Oral Administration of Semisolid Cellulose-Based Gastric Ultrasound Contrast Agents.

Many previous studies have found that transabdominal ultrasound may allow precise measurement of gastric emptying of liquid meals. However, the clinical use of this technique has been hampered by the limitation that transabdominal ultrasound might not accurately measure gastric emptying of solid meals. It is more important to measure gastric emptying of solids instead of liquids, as gastric emptying of solids is more often delayed than gastric emptying of liquids in gastric motility disorders.

2D amphiphilic organoplatinum(ii) metallacycles: their syntheses, self-assembly in water and potential application in photodynamic therapy.

Two 2D amphiphilic organoplatinum(ii) metallacycles with a porphyrin unit as the core and hydrophilic glycol units as the tail were designed and fabricated successfully through a new method called "coordination-driven self-assembly". They can self-assemble into micelles in water and have potential applications in photodynamic therapy.
