Why can Tween be better than Pluronic in forming smaller nanostructured lipid carrier?
5 answers
Tween can be more advantageous than Pluronic in forming smaller nanostructured lipid carriers due to its impact on reducing particle size and enhancing stability. The incorporation of Tween nonionic surfactants, such as Tween 80, in nanostructured lipid carriers (NLC) has been shown to significantly decrease the average size of the carriers to 139.9 ± 15.8 nm, ensuring stability even after 28 days of incubation. Additionally, Tween has been found to increase encapsulation efficiency, with formulations incorporating Tween 60 showing the highest efficiency at 99.7%. On the other hand, Pluronic block copolymers, while effective in drug delivery systems, primarily function as biological response modifiers rather than solely reducing particle size. Therefore, Tween's ability to reduce particle size and enhance stability makes it a preferable choice over Pluronic for forming smaller nanostructured lipid carriers.
How is the process of transporting oxygen to the muscles?
4 answers
The process of transporting oxygen to the muscles involves a complex interplay of various physiological mechanisms. Oxygen is transported from the atmosphere to muscle mitochondria through five major stages: lungs, erythrocytes, microcirculation, muscle, and mitochondria. During exercise, the oxygen flux increases significantly, demanding precise coordination among the pulmonary, cardiovascular, and muscle microcirculation systems. The microcirculation plays a crucial role in distributing oxygen to every myocyte, with capillaries forming a dense network for efficient exchange of oxygen and other substrates within the muscles. Interstitial flow in the tissue contributes to active convective oxygen transport, which can be more efficient than passive diffusion, especially in delivering oxygen to specific muscle fiber types. Understanding the dynamics of oxygen transport close to muscle mitochondria is essential for identifying disease mechanisms and developing therapeutic interventions to address exercise intolerance.
