Deciphering the dynamic single-cell transcriptional landscape in the ocular surface ectoderm differentiation system.

The ocular surface ectoderm (OSE) is essential for the development of the ocular surface, yet the molecular mechanisms driving its differentiation are not fully understood. In this study, we used single-cell transcriptomic analysis to explore the dynamic cellular trajectories and regulatory networks during the differentiation of embryonic stem cells (ESCs) into the OSE lineage. We identified nine distinct cell subpopulations undergoing differentiation along three main developmental branches: neural crest, neuroectodermal, and surface ectodermal lineages.

Effect of KRAS mutation status on clinicopathological characteristics and overall survival in patients with rectal cancer.

Background: KRAS mutations in rectal cancer are associated with a conflict prognosis. This study aimed to compare clinicopathological outcomes of patients and tumor criteria between wKRAS and mKRAS, as well as overall survival in the two groups.

Methods: The research retrospectively analyzed a cohort of 193 patients who received surgical treatment for rectal adenocarcinoma between May 2015 and December 2023.

Development of a predictive nomogram for postoperative acute respiratory distress syndrome in Stanford type A aortic dissection patients: a retrospective study.

Introduction And Objectives: This retrospective study aimed to develop a nomogram to predict the risk of postoperative acute respiratory distress syndrome (ARDS) in patients with Stanford type A acute aortic dissection.

Methods: The study included patients who underwent surgical repair for Stanford type A acute aortic dissection between January 2020 and December 2023. Demographic data, surgical details, intraoperative information, and postoperative outcomes were collected.

Maize transcription factor ZmEREB167 negatively regulates starch accumulation and kernel size.

Transcription factors play critical roles in the regulation of gene expression during maize kernel development. The maize endosperm is a large storage organ, accounting for nearly 90% of the dry weight of mature kernel, and is also the main place for starch storage. In this study, we identify an endosperm-specific EREB gene, ZmEREB167, which encodes a nucleus-localized EREB protein.

Prevention strategies of esophageal stenosis after endoscopic resection for superficial esophageal cancer: a Bayesian network meta-analysis.

Introduction: What interventions effectively prevent postoperative stenosis following endoscopic resection (ER) of superficial esophageal cancer? This study aimed to identify effective interventions or combinations through a systematic review and network meta-analysis.

Methods: Six databases were systematically searched for eligible studies up to 30 April 2023, on interventions to prevent esophageal stenosis post-ER. Odds ratios (ORs) evaluated stenosis rate (primary outcome) and complications (secondary outcome), while mean differences (MD) evaluated endoscopic balloon dilatation (EBD) sessions post-stenosis.
