[EX Q]: Question: Does classical swine fever virus induce oxidative stress in swine umbilical vein endothelial cells?
Answer: Our results indicated that CSFV infection induced oxidative stress in SUVECs. These findings provide novel information on the mechanism by which CSFV can alter intracellular events associated with the viral infection.
[EX A]: yes

[EX Q]: Question: Do several mechanical manipulations of the wall of the inner ear affect air and bone conduction auditory thresholds?
Answer: It is likely that an alternative mode of cochlear excitation is possible.
[EX A]: no

[EX Q]: Question: Does mast cell deficiency exacerbate inflammatory bowel symptoms in interleukin-10-deficient mice?
Answer: Mast cell deficiency in IL-10-deficient mice resulted in systematic and gut inflammation, impaired gut barrier function, and severer Th1-mediated colitis when compared to mice with only IL-10-deficiency. Inflammation and impaired gut epithelial barrier function likely form a vicious cycle to worsen colitis in the DKO mice.
[EX A]:
yes
