Therapies targeting VEGF have proven only modestly effective for the treatment of proliferative sickle cell retinopathy (PSR), leading cause blindness in patients with disease. Here, we shift our attention upstream from genes that promote retinal neovascularization (NV) to transcription factors regulate their expression.

Background Tuberculosis (TB) is a disease caused by the chronic and continuous infection of pathogen Mycobacterium tuberculosis (M. tuberculosis). M. an intracellular bacterial eliminated mainly through CD4+ effector Th cells. induces regulatory T lymphocytes (Tregs) that mediate immune suppression cell-to-cell contact or secreting cytokines such as transforming growth factor-β (TGF-β). To understand role T-cells in pathogenesis TB, we have measured vivo frequency associated cytokine...
Transrectal ultrasound (TRUS)-guided biopsy is the standard procedure for evaluating presence and aggressiveness of prostate cancer. TRUS involves tissue removal, suffers from low core yield as well high false negative rate. A less invasive more accurate diagnostic cancer therefore highly desired. Combining optical sensitivity ultrasonic resolution to resolve spatial distribution major molecular components in tissue, photoacoustic (PA) technology could be an alternative approach diagnosis...
