Updates in lung isolation techniques.

Innovations and challenges for lung separation or isolation have evolved during the last few years. In this chapter, we present the up-to-date, robust evidence available during the previous five years supporting the positions of the different devices, techniques, and tricks for their use in adult and pediatric patients undergoing various thoracic surgical interventions. Additionally, we presented an update on lung isolation in patients with airway difficulty and the suggested training level to master these techniques.

Surgical Versus Conservative Management of Delayed Presentation of Acute Biliary Disease: A Systematic Literature Review.

Biliary sepsis, characterized by contamination and infection of the biliary tract, poses a serious medical issue with detrimental effects on the patients. While cholecystectomy is the usual treatment for symptomatic gallstones, the most desirable management approach for biliary sepsis remains debated, prompting a scientific evaluation of the long-term effects of cholecystectomy. To compare the long-term outcomes of biliary sepsis in patients undergoing cholecystectomy versus conservative management (CM), this study will systematically review the existing literature to clarify differences in recurrence rates, complication rates, and overall survival.

Stearic acid-capped mesoporous silica microparticles as novel needle-like-structured drug delivery carriers.

Mesoporous silica are widely utilised as drug carriers due to their large pore volume and surface area, which facilitate effective loading. Additionally, they can be used to enhance drugs stability and protect against enzymatic degradation due to their silica framework. However, without the addition of a capping material, the loaded cargo may be prematurely released before reaching the target site.

Pioneering Advances and Innovative Applications of Mesoporous Carriers for Mitochondria-Targeted Therapeutics.

Mitochondria, known as the cell's powerhouse, play a critical role in energy production, cellular maintenance, and stemness regulation in non-cancerous cells. Despite their importance, using drug delivery systems to target the mitochondria presents significant challenges due to several barriers, including cellular uptake limitations, enzymatic degradation, and the mitochondrial membranes themselves. Additionally, barriers in the organs to be targetted, along with extracellular barriers formed by physiological processes such as the reticuloendothelial system, contribute to the rapid elimination of nanoparticles designed for mitochondrial-based drug delivery.
