Progression of resectable pancreatic ductal adenocarcinoma during surgical delay and effects on survival - A propensity score matched study.

Background: Surgery is the only curative treatment for pancreatic cancer, but less than 25 % of the patients present with a resectable tumor at the time of diagnosis. The aim of this study is to evaluate progression during surgical treatment delay and examine any associations between surgical treatment delay and survival.

Methods: This is a retrospective, single center propensity score matched study including treatment naïve patients with pancreatic adenocarcinoma between 2018 and 2022.

Experimental and DFT Approaches to Physico-Chemical Properties of Bioactive Resveratrol Analogues.

Acetylcholinesterase and butyrylcholinesterase are two related enzymes that represent pharmacologically suitable targets in neurodegenerative disorders, given their physiological roles in the body. The treatment of neurodegenerative disorders currently includes common reversible cholinesterase inhibitors. Resveratrol analogues, as the molecules in focus, have shown the very strong inhibition potential of cholinesterases.

Advanced drug delivery strategies for diabetic retinopathy: current therapeutic advancement, and delivery methods overcoming barriers, and experimental modalities.

Introduction: Diabetic retinopathy, a significant trigger for blindness among working age individuals with diabetes, poses a substantial global health challenge. Understanding its underlying mechanisms is pivotal for developing effective treatments. Current treatment options, such as anti-VEGF agents, corticosteroids, laser photocoagulation, and vitreous surgery, have their limitations, prompting the exploration of innovative approaches like nanocapsules based drug-delivery systems.

Characterization of Anticancer Drug Protomers Using Electrospray Ionization and Ion Mobility Spectrometry-Mass Spectrometry.

We used electrospray ionization and ion mobility spectrometry-mass spectrometry to detect and characterize the three anticancer drugs palbociclib, copanlisib, and olaparib. Ion mobility-mass spectrometry and density functional theory revealed that these compounds generate isomers during ionization (protomers) due to the presence of multiple protonation sites within their chemical structures. Our work has implications for understanding the solution- and gas-phase chemistry of these molecules during spray-based ionization processes.
