Research on method to open blood-brain barrier for safe cancer drug delivery

One of the human body's most powerful defensive tools, the blood-brain barrier is a chemical labyrinth that prevents toxins and viruses in the bloodstream from reaching the brain. This foolproof security system, however, limits the ability of physicians to deliver drugs directly to the brain, making it difficult to treat brain tumors. Researchers at Rensselaer Polytechnic Institute are endeavoring to solve this problem by investigating new methods for bypassing the blood-brain barrier and combating the spread of brain cancer.

New microfluidic device for effective HIV diagnosis

UC Davis biomedical engineer Prof. Alexander Revzin has developed a "lab on a chip" device for HIV testing. Revzin's microfluidic device uses antibodies to "capture" white blood cells called T cells that are affected by HIV. In addition to physically binding these cells the test detects the types and levels of inflammatory proteins (cytokines) released by the cells.

Study compares denture stomatitis genes with whole transcriptome for salivary biomarker analysis

The goal of the study was to compare whole-transcriptome, mucosal gene expression in Candida albicans (a parasitic fungus that can infect the mouth) associated chronic denture stomatitis to that of healthy oral mucosa and perform proteomic analyses of potential salivary biomarkers. Denture stomatitis is a condition in which the mucosa underneath a denture becomes inflamed and sometimes painful.

Scientists use PGS method to analyse chromosomal status of eggs

The efficacy of preimplantation genetic screening has been one of the most hotly disputed subjects in assisted reproduction over the past few years. The European Society of Human Reproduction and Embryology PGS Task Force has now shown, in its groundbreaking proof of principle study, that screening of polar bodies (small cells that are the by-product of egg development), is a reliable method to analyse the chromosomal status of an egg.

New biomarker study explores early detection of ovarian cancer

Despite many research advances, ovarian cancer remains lethal in a majority of cases, due to late diagnosis of the disease. In a new study, Dr. Joshua LaBaer of the Biodesign Institute at Arizona State University, along with Arturo Ramirez and Paul Lampe, researchers at the Fred Hutchinson Cancer Research Center in Seattle, used a novel method for identifying biomarkers-proteins in blood that can identify ovarian cancer before symptoms appear.
