Pivotal components of the IFN response to virus infection include the IFN receptors (IFNR), and the downstream factorsignal transducer and activator of transcription 1 (Stat1). Mice deficient for Stat1 and IFNR (Stat12/2 and IFNaßcR2/2 mice) lack responsiveness to IFN and exhibit high sensitivity to various pathogens. Here we examined herpes simplex virus type 1 (HSV-1) pathogenesis in Stat12/2 mice and in IFNaßcR2/2 mice following corneal infection and bioluminescent imaging. Two divergent and paradoxical patterns of infection were observed. Mice with an N-terminal deletion in Stat1 (129Stat12/2(N-term)) had transient infection of the liver and spleen, but succumbed to encephalitis by day …

Clinical extracorporeal shock wave lithotripsy (ESWL) treatment to ablate kidney stones can cause acute damage to the renal microvasculature. Accumulation of continued treatment with shockwave therapy can lead to chronic damage to the kidney, and lead to clinical hypertension. Shockwaves have been shown to stimulate endothelial cells to release superoxide (SO), which is converted to hydrogen peroxide (H2O2), and reacts with nitric oxide (NO) to produce peroxynitrite anion (OONO-), creating a powerful oxidant that increases oxidative stress while simultaneously reducing NO bioavailability. Increased oxidative stress during events such as ESWL, also uncouples NO production …
