Fatal complications of aortoesophageal fistula caused by pseudoaneurysm following esophageal stent placement: A case report.

Rationale: Aortoesophageal fistula (AEF) is an exceedingly rare yet critically life-threatening condition, with mortality rates nearing 100% if not addressed promptly. AEF often develops in the context of thoracic aortic aneurysms, esophageal malignancies, or as a complication of foreign body ingestion and prior thoracic aortic surgeries. This study reports an exceptionally severe and clinically rare case of AEF associated with a pseudaneurysm induced by esophageal stenting.

Development of a nomogram for overall survival in patients with esophageal carcinoma: A prospective cohort study in China.

Background: Esophageal carcinoma (EC) presents a significant public health issue in China, with its prognosis impacted by myriad factors. The creation of a reliable prognostic model for the overall survival (OS) of EC patients promises to greatly advance the customization of treatment approaches.

Aim: To create a more systematic and practical model that incorporates clinically significant indicators to support decision-making in clinical settings.

Identification and quantification of five impurities in cloperastine hydrochloride.

Cloperastine hydrochloride, a piperidine derivative, is a drug substance with a central antitussive effect and widely used in cough treatment; and its impurities have not been reported. Herein we isolated and identified five impurities (named as impurity A, B, C, D and E) in cloperastine hydrochloride bulk drug and developed a quantitative HPLC method. First, impurity A, B, C were enriched by ODS column chromatography and isolated by semi-preparative HPLC, at the same time, impurity D was purified by ODS column chromatography.

HMGB1-Induced p62 Overexpression Promotes Snail-Mediated Epithelial-Mesenchymal Transition in Glioblastoma Cells via the Degradation of GSK-3β.

Glioblastoma (GBM) is the most common and aggressive brain tumor, characterized by its propensity to invade the surrounding brain parenchyma. The effect of extracellular high-mobility group box 1 (HMGB1) protein on glioblastoma (GBM) progression is still controversial. p62 is overexpressed in glioma cells, and has been associated with the malignant features and poor prognosis of GBM patients.

HERC3-Mediated SMAD7 Ubiquitination Degradation Promotes Autophagy-Induced EMT and Chemoresistance in Glioblastoma.

Purpose: Glioblastoma, a common malignant intracranial tumor, has the most dismal prognosis. Autophagy was reported to act as a survival-promoting mechanism in gliomas by inducing epithelial-to-mesenchymal transition (EMT). Here, we determined the critical molecules involved in autophagy-induced EMT and elucidated the possible mechanism of chemoradiotherapy resistance and tumor recurrence.

Endoscopic ultrasound elastography in the diagnosis of pancreatic masses: A meta-analysis.

Background And Aims: Endoscopic ultrasound (EUS) elastography is a novel non-invasive technique that can be used for distinguishing benign from malignant pancreatic masses. However, the studies have reported widely varied sensitivities and specificities. A meta-analysis was performed to assess the performance of EUS elastography for the differentiation of benign and malignant pancreatic masses.

Characterization of a novel rice metallothionein gene promoter: its tissue specificity and heavy metal responsiveness.

The rice (Oryza sativa L.) metallothionein gene OsMT-I-4b has previously been identified as a type I MT gene. To elucidate the regulatory mechanism involved in its tissue specificity and abiotic induction, we isolated a 1 730 bp fragment of the OsMT-I-4b promoter region.
