Transferrin-modified carboxymethyl chitosan-chitosan nanoparticles as an efficient delivery carrier for targeted therapy of depression.

Limitations of the blood-brain barrier (BBB) are responsible for the low efficacy and high toxicity of many antidepressants. However, strategies to enhance BBB targeting to improve the efficacy and safety of antidepressants remain challenging. In this study, we prepared transferrin (Tf)-functionalized chitosan (CS)-N,O-carboxymethy chitosan (NOCMS) nanosystems (NPs) (NOCMS-CS-Tf NPs), which can enhance BBB targeting in the depressive environment and allow more NPs to enter the brain.

Active Fraction of Polyrhachis Vicina Roger (AFPR) Ameliorate Depression Induced Inflammation Response by FTO/miR-221-3p/SOCS1 Axis.

Purpose: Neuroinflammation is a significant etiological factor in the development of depression. Traditional Chinese medicine (TCM) has demonstrated notable efficacy in the treatment of inflammation. Our previous study surfaces that the active fraction of Roger (AFPR) has antidepressant and anti-neuroinflammatory effects, but the specific mechanisms remain to be elucidated.

Evaluation of the diagnostic efficacy of liquid-based cytology obtained via percutaneous ultrasound-guided fine-needle aspiration for pancreatic masses: a large tertiary center's 8-year experience.

Purpose: There were limited data on the diagnostic efficacy of liquid-based cytology (LBC) for pancreatic tissues acquired by percutaneous ultrasound-guided fine-needle aspiration (US-FNA). This study aimed to evaluate the diagnostic value of LBC acquired via percutaneous US-FNA for pancreatic tumors compared with LBC combined with smear cytology (SC).

Methods: A retrospective database search (January 2014 and February 2022) was performed for patients who underwent percutaneous US-FNA with both LBC and SC.
