Magnetic permeability is the ability of a material to become magnetized in a magnetic field. It is measured in henres per meter or newton per ampere squared. Air in a vacuum has a constant value called the magnetic constant. Permeability changes with location, frequency, humidity, temperature, and other factors. Substances are classified as paramagnetic, diamagnetic, […]
Selective permeability is the ability of a cell membrane to control which molecules can enter or leave the cell. This can occur through passive transport, active transport, or vesicles. The size, charge, and solubility of molecules affect permeability, which is essential for sustaining life. In cell biology, selective permeability is the property of a living […]
Vascular permeability is regulated by the endothelium and determines which molecules can pass through blood vessels. VEGF is the major determinant and is linked to cancer, but inhibiting it could prevent the spread of malignant tumors. Animal studies have shown some control of permeability in colon, brain, and breast cancer. Vascular permeability studies have also […]
