Smart insulin nanostructures pass feasibility test, UT study reports

... named concanavalin A (Con A) and bundles of tiny fat bubbles called liposomes that are loaded with insulin. Con A binds insulin-containing liposomes that are coated with sugars, to each other, to form the inhaled particles, ...

Scientists Test New Way to Get Drugs to Cancer Cells

... can be manipulated to control how long they remain in the bloodstream. Johns Hopkins University researchers attached cancer-specific antibodies to liposomes to create immunoliposomes that travel through the bloodstream and seek out tumors. When they come in contact with tumors, the immunoliposomes deliver ...

Potential for noninvasive brain tumor treatment

... system in conjunction with chemotherapy drugs encased in heat-sensitive microbubbles called liposomes. "Physicians would inject drug-carrying liposomes into a patient's bloodstream, and then insert a catheter via a blood vessel to the site of the brain tumor," said Carl Herickhoff, fourth-year ...

Transave Completes Enrollment in Arikace(TM) Phase II Bronchiectasis Study

... systemic exposure. The treatment uses biocompatible lipids endogenous to the lung that are formulated into small (0.3 micron), neutrally-charged liposomes that enable penetration of the biofilm and are highly efficient, with a very low lipid-to-drug ratio (0.65). Arikace can be delivered through ...

Nanomedicine system engineered to enhance therapeutic effects of injectable drugs

... with tiny drug-encapsulated fat bubbles called liposomes, now commonly used in cancer clinics worldwide. Targeting molecules were later added to liposomes and other nanovectors to assist in directing them to diseased cells, Ferrari said. Getting intravenous agents to their intended targets is no easy ...

ImmunoVaccine Technologies Receives $3 Million From ACOA

... Technologies Inc. (IVT) has developed a breakthrough vaccine-enhancement technology - the VacciMax(R) platform. It is comprised of a mixture of liposomes and adjuvants. The VacciMax(R) platform is able to stimulate an earlier, more powerful, long lasting immune response that could provide a new way to ...

Tiny Sphere Of Nanoparticles Can Fight Cancer

... from women with advanced cancer were treated for 3-5 weeks. They received liposomes that contained either the FAK siRNA, a control siRNA, or were empty. Some mice received siRNA liposomes plus the chemotherapy docetaxel. Mice receiving the FAK-silencing ...

Novel Method to Inhibit Prostate Cancer

... drugs to disseminated prostate metastases is one of the most challenging goals in prostate cancer therapy. Drug carriers -- nanoemulsions, liposomes (fatty droplets) and nanoparticles -- have shown great potential as delivery systems for an increasing number of active molecules. Although ...

Carbon Nanoneedles For Drug Delivery

... the technique could offer significant advantages over other drug delivery mechanisms currently used. Traditional delivery methods (using liposomes for example) usually exploit endocytosis, but stop before reaching the cytoplasm leaving other barriers for the drug to fight through. By piercing ...
