Term
Autophagy
Definition
Intracellular digenstion of interalcellular material
Term

Definition
It liberates building blocks that can be used by the clell particularly when the cell cannot get enough food from outside.
Term
Autolysis occurs due to
Definition

Term

Definition
  1.  
    1. in cell injury and death
    2. when the cells are programmed to die
    3. in tissue regression
Term
Additional functions of Lysosomes
Definition
Term
application of Liposomes
Definition

magic bullets

cancer treatment

gene therapy

Term
Stealth liposome
Definition

Coat liposomes with polyethylene glycol.

This prevents the molecular flags(opsonins) from combining with liposomes, thus evading recognition by macrophages.

Term
Mimic
Definition

Coat liposomes with sialic acid, and mimic the RBC membrane, thereby evading macrophage recognition.

Term
Arthritic Gout
Definition
  • Absence of uricase enzyme.
  • Uric acid cannot be metabolized. It combines with sodium to form monosodium urate crystals(MSU)
