The critical factor that governs tissue tropism is the modulation of the surface's acid dissociation constant (pKa), which corresponds to the pH at which the proportion of charged and uncharged ionizable lipids at the particle's surface is equal and depends on the type of ionizable lipids and charged helper lipids used in the nanoparticle ...
Development of solid lipid nanoparticles is one of the emerging fields of lipid nanotechnology (for a review on lipid nanotechnology, see [16]) with several potential applications in drug delivery, clinical medicine and research, as well as in other disciplines. Due to their unique size-dependent properties, lipid nanoparticles can possibly ...
Gleason scores are often grouped together, based on similar behaviour: Grade 2-4 as well-differentiated, Grade 5-6 as intermediately-differentiated, Grade 7 as moderately to poorly differentiated (either 3+4=7, where the majority is pattern 3, or 4+3=7 in which pattern 4 dominates and indicates less differentiation., [6] and Grade 8-10 as "high ...
SLNs can be made by replacing the liquid lipid oil used in the emulsion process with a solid lipid. In solid lipid nanoparticles, the drug molecules are dissolved in the particle's solid hydrophobic lipid core, this is called the drug payload, and it is surrounded by an aqueous solution. [6]
Nanomedicine is the medical application of nanotechnology. [1] Nanomedicine ranges from the medical applications of nanomaterials and biological devices, to nanoelectronic biosensors, and even possible future applications of molecular nanotechnology such as biological machines.
When the blood vessels form so rapidly, large fenestrae result that are 100 to 600 nanometers in size, which allows enhanced nanoparticle entry. Further, the poor lymphatic drainage means that the large influx of nanoparticles are rarely leaving, thus, the tumor retains more nanoparticles for successful treatment to take place. [8]
Of the many cancer-specific schemes, the Gleason system, [3] named after Donald Floyd Gleason, used to grade the adenocarcinoma cells in prostate cancer is the most famous. This system uses a grading score ranging from 2 to 10. Lower Gleason scores describe well-differentiated less aggressive tumors.
The use of a tethered bilayer lipid membrane (t-BLM) further increases the stability of supported membranes by chemically anchoring the lipids to the solid substrate. [33] Diagram showing formation of t-BLM. Gold can be used as a substrate because of its inert chemistry and thiolipids for covalent binding to the gold.
