ADAM is an injectable hydrogel designed specifically for the dynamic environment of the vas deferens. Unlike RISUG and Vasalgel, which require injection in organic solvent, ADAM is aqueous-based. The ADAM hydrogel is inserted through a minimally-invasive, outpatient procedure.
The hysteresis of a hydrogel refers to the phenomenon where there is a delay in the deformation and recovery of a hydrogel when it is subjected to mechanical stress and relieved of that stress. This occurs because the polymer chains within a hydrogel rearrange, and the water molecules are displaced, and energy is stored as it deforms in ...
In order to attain high transgene expression, the electrostatic interaction between the gene and hydrogel polymer and the controlled release of the drug payload from the hydrogel is necessary. [36] Several gene therapy drugs used in hydrogel-based drug delivery systems include CRISPR/Cas9, [58] siRNA, [40] [59] and other RNA-based drugs. [59]
ADAM is a hydrogel-based male contraceptive implant in early clinical development [151] by Contraline, Inc. [152] The implant is administered to a user in a procedure similar to a no-scalpel vasectomy, and is proposed to provide protection from pregnancy for approximately two years, after which the hydrogel degrades, thereby restoring fertility ...
The porous structure of this material would also make the process of drug delivery easier where the pharmaceutical compounds present in the hydrogel can easily escape and be absorbed by the body. Aside from that, researchers are also looking into incorporating nanocomposite hydrogels with silver nanoparticles for antibacterial applications and ...
Stroger employs 300 attending physicians and over 400 fellows and residents. It has 1.2 million square feet (110,000 m 2) of floor space, and 464 beds.It is located at 1901 W. Harrison Street, and is a part of the 305 acre (1.2 km 2) Illinois Medical District on Chicago's West Side, which is one of the largest concentrations of medical facilities in the world.
A nanogel is a polymer-based, crosslinked hydrogel particle on the sub-micron scale. [1] [2] [3] These complex networks of polymers present a unique opportunity in the field of drug delivery at the intersection of nanoparticles and hydrogel synthesis.
Four different purified hyaluronidases have been approved for use in the United States, three of animal origin and one recombinant. They are indicated as adjuvants in subcutaneous fluid administration for achieving hydration, for increasing the dispersion and absorption of other injected drugs, or for improving resorption of radiopaque agents, in subcutaneous urography.
