Novel ChABC formulation with machine learning-guided automation
Invention Summary:
Spinal cord injury (SCI) leads to the formation of scar tissue. The scarring leads to the toughening of the extracellular matrix, or the cellular environment. One of the major concerns of SCI is the prevention of neuronal connection recovery, which can lead to paralysis or reduced control of the nervous system. For...

Amphiphilic macromolecules with novel hydrophobic segments
Invention Summary:
Cardiovascular diseases are the leading cause of mortality in developed countries. Atherosclerosis, defined as the buildup of lipid rich plaques within the vascular intima, is the foremost pathology underlying these conditions. This causes irregular uptake of oxidized low-density lipoproteins (OxLDL) which leads...
