Africa's first large-scale HIV vaccine study launches

...ith this vaccine suggest that it is generally well tolerated and that the response of the immune system or immunogenicity is high. In South Africa, the vaccine trial is called "Phambili," which means "moving forward" in the Xhosa language. Volunteers will be healthy HIV negative males and females, aged 18...

Intravenous nanoparticle gene therapy shows activity in stage IV lung cancer

...disease. The clinical trial continues. No maximum tolerated dose has been established, Lu says. The nanoparticle delivery system consists of a plasmid gene expression cassette loaded with DNA that encodes the FUS1 protein. This is wrapped tightly in a form of cholesterol to protect it from the body's def...

An artificial cornea is in sight, thanks to biomimetic hydrogels

...or biocompatibility in animal models. Animals have tolerated artificial corneas with no problems in trials as long as eight weeks, Ta says. The material remains perfectly clear, he says. Longer trials are a next step. The current source of tissue for corneal transplants is cadavers. Donor tissue has problems...

Radiotherapy advance points way to noninvasive brain cancer treatment

...the tumor and radiation treatment with the maximum tolerated dose - all of which leads to a painfully low quality of life. Because of this, researchers are racing to find better therapies to stop or slow GBM. In the Jan. 1, 2006 issue of the journal Clinical Cancer Research, Gelsomina "Pupa" De Stasio, profes...

Gene variation increases SIDS risk in African Americans

Compound from marine bacteria shows potential as multiple myeloma therapy

...ive than using either therapy alone ?and be better tolerated by patients as well. In preclinical studies, NPI-0052 blocks a wider range of proteasome activities than bortezomib, say the researchers, and works at lower doses. NPI-0052 also appears to be less toxic to normal cells. Bortezomib is currently gi...
