Reactive light microscopy
WebWidefield and confocal fluorescence microscopy are capable of magnifying and imaging light-emitting fluorophores with a resolution that approaches a quarter of a micrometer, thus enabling the study of dynamic events and … WebJan 1, 2011 · A reactive treponemal test confirms the diagnosis of a new or previously treated case of syphilis. If the treponemal test is non-reactive, the positive non-treponemal test result is considered a biologic false-positive that is not diagnostic of syphilis.

WebJan 9, 2024 · The produced cytokines afterward prompt white blood cells (leukocytes) to release reactive oxygen species (ROS) and reactive nitrogen species (RNS) that can kill bacteria and viruses. Unfortunately, ROS/RNS also cause collateral damage and can have negative effects on the cells themselves. WebReactive oxygen species (ROS) develop as a consequence of wounding, light stress and chemical imbalances but act also as signals in living cells. The integrity of cells is seriously endangered, if ROS cannot be controlled by scavenging molecules and other repair mechanisms of the cell.
