Patent number: 10329326Abstract: The subject invention pertains to a modified MC1R peptide ligand comprising a peptide that is a melanocortin 1 receptor (MC1R) ligand and a functionality or linker, such as a click functionality, for conjugation to a surface or agent. The modified MC1R peptide ligand can be coupled, e.g., via a click reaction with a complementary click functionality attached, to a moiety to form an MC1R-targeted agent. Drugs, contrast agents, polymers, particles, micelles, surfaces of larger structures, or other moieties can be targeted to the MC1R. The subject invention also pertains to a MC1R peptide ligand-micelle complex comprising a peptide that is a melanocortin 1 receptor ligand connected via a click reaction product to a micelle. The micelle is stable in vivo and can target melanoma tumor cells by association of the peptide ligand with the MC1R or the tumor and selectively provide a detectable and/or therapeutic agent (such as an imageable contrast agent and/or anti-cancer agent) selectively to the tumor cell.Type: GrantFiled: September 12, 2016Date of Patent: June 25, 2019Assignees: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONA, BOARD OF REGENTS, UNIVERSITY OF TEXAS SYSTEM, H.

Patent number: 10118942Abstract: Disclosed are monoacylated Toll-like receptor 2 ligands which can be used in both the development of targeted agents for the imaging and treatment of pancreatic cancer as well as other cancers, and as an adjuvant for cancer immunotherapy. The monoacylated compounds disclosed herein have a higher binding affinity for TLR2 relative to a known potent diacylated agonists, but only ?½ the bioactivity. Competition of the monoacylated compound with the diacylated compound for binding TLR2 was confirmed. Hence, the reported monoacylated compounds are inhibitors/antagonists of TLR2 activation.Type: GrantFiled: March 25, 2016Date of Patent: November 6, 2018Assignees: H.

Patent number: 6573026Abstract: A method of writing a pattern, such as a waveguide, in a bulk glass substrate. The bulk glass substrate can be formed from, for example, borosilicate or sulfide or lead glass. A pulsed laser beam is focused within the substrate while the focus is translated relative to the substrate along a scan path at a scan speed effective to induce an increase in the refractive index of the material along the scan path. Substantially no laser induced physical damage of the material is incurred along the scan path. Various optical devices can be made using this method.Type: GrantFiled: July 28, 2000Date of Patent: June 3, 2003Assignee: Corning IncorporatedInventors: Bruce G. Aitken, Nicholas F.

Patent number: 5937125Abstract: A detachable fiber optic connector has an improved nose block (800) which enhances cooling of power dissipating components, simplifies assembly, improves yield and reduces cost. The improved nose block (800) includes an upper tray (802) and lower tray (804) which slidingly receive an improved aluminum nitride optical subassembly (700). The subassembly (700) and nose block (800) are held together, properly aligned, and then fixated. The nose block (800) also has symmetrical protrusions (850) which allow the nose block (800) to be placed easily and precisely into mating protrusions (230, 240) in a seal ring (200). The nose block (800) provides a direct thermal pathway between power dissipating components, such as an opto-electronic component (750) and optical driver IC (730), and an aluminum package base (400). Various alternative nose blocks (810, 820, 830) are illustrated, and an alternative base (410) is also shown.Type: GrantFiled: August 19, 1997Date of Patent: August 10, 1999Assignee: CTS CorporationInventors: Steven B.
