The aim of the paper is to give a contribution to the understanding of the role of surgery in patients with N3 lung cancer. The A. describe their results on 32 patients with N3 lung cancer operated on mediastinectomy; histological examination of the specimens showed 27 squamous cell carcinomas and 5 adenocarcinomas. The operation was performed through a median sternotomy to gain access to the left and right paratracheal nodes, pretracheal, precarinal and subcarinal nodes, subaortic and left and right hilar nodes that were removed together with the fat of the mediastinum. Left pneumonectomy was performed in 5 patients. There was no operative mortality; 12 patients were irradiated in the postoperative period with 5,000 Rads (50 Gy), while 18 or the 27 patients with squamous cell carcinoma are still alive.

Background: The body weight following bariatric surgery is a primary concern for both healthcare professionals and surgical candidates. However, it remains unclear whether variations in preoperative fat distribution influence weight loss outcomes.
Objective: The aim of this study was to evaluate the effect of abdominal fat distribution on postoperative weight loss and body mass index (BMI) reduction, and to clarify the role of different fat depots in weight loss outcomes.

Breast cancer continues to be a major health issue for women worldwide, with vimentin (VIM) identified as a crucial factor in its progression due to its role in cell migration and the epithelial-to-mesenchymal transition (EMT). This study focuses on elucidating VIM's regulatory mechanisms on the miR-615-3p/PICK1 axis. Utilizing the 4T1 breast cancer cell model, we first used RNA-seq and proteomics to investigate the changes in the APA of PICK1 following VIM knockout (KO).

Chemotherapy resistance is a great challenge in the treatment of gastric cancer (GC), so it is urgent to explore the prognostic markers of chemoresistance. PUF60 (Poly (U)-binding splicing factor 60) is a nucleic acid-binding protein that has been shown to regulate transcription and link to tumorigenesis in various cancers. However, its biological role and function in chemotherapy resistance of GC is unclear.
