USC researchers develop low-cost blood test for early Alzheimer’s detection

Researchers from USC Keck School of Medicine have developed a low-cost blood test that detects five biomarkers of Alzheimer's disease, including amyloid and tau proteins. The test uses xMAP technology and has the potential to catch the disease in its earliest stages, when treatment might be able to prevent or delay cognitive decline.

Novel blood-based biomarker analysis provides insights to improve therapy decisions and treatment outcomes for patients with metastatic disease

Researchers identified platelets, C-reactive protein, and chromogranin A as markers that can predict the failure of hormone-sensitive prostate cancer treatment. The study also found that miR-375 expression and lymphocyte-to-monocyte ratio are negative predictors for therapy failure in castration-resistant prostate cancer patients.
