Hair cell death caused by acute acoustic trauma (AAT) reaches a secondary maximum at 7-10 days after noise exposure due to a second oxidative stress. Therefore, this study tested the effects of a combination of hydroxylated alpha-phenyl-tert-butylnitrone (4-OHPBN), N-acetyl-L-cysteine (NAC) and acetyl-L-carnitine (ALCAR) on AAT when the duration of treatment was extended over the period of 7-10 days after noise exposure as well as when the initial treatment was delayed 24 to 48 h after noise exposure.
We consider an extension of the Randall-Sundrum model with three parallel
3-branes in a 5-dimensional spacetime. This new construction, apart from
Providing a solution to the Planck hierarchy problem, has the advantage that
The SM fields are confined on a positive tension brane. The study of the
