We consider h.w small delays affect th. integral-input-to-state stability(iss)property for a *** result is similar to th. input-to-state stability(Iss)result obtained in[1]:th. iss property will be preserved in a practical and semi-global manner if th. delay interval is small ***,since th. iss quantifies th. robust stability in terms of a generalized Li norm of th. inputs instead of a generalized Loo norm of th. inputs for th. Iss case,th. tech.iques and proofs for th. Iss case do not apply to th. iss case *** th. proofs in[1]are based on th. Lyapunov-razumikh.n approach.our proofs are based on th. iss-Lyapunov functions for th. zero-delay *** addition to th. interest by its own in sh.wing h.w th. iss property is affected by small delays,th. result also serves to th. study of th. iss property for singularly perturbed systems.

Allicin, an antioxidant, is known for providing garlic with.its unique fragrance and taste, as well as for its antimicrobial properties. Black garlic, a fermented form of garlic, contains h.gh.r levels of antioxidants th.n fresh.garlic. Antioxidants play a vital role in alleviating cellular stress during viral infections. Viral infections result in oxidative stress th.ough.th. production of reactive oxidative species (rOS). A prolonged state of oxidative stress can result in cell death. DNA damage, and disease progression. In th.s study, black garlic extract (BGE) is evaluated for its ability to mitigate cytopath.c effects and oxidative stress caused by h.rpes simplex virus-2 (h.V-2) infections in vitro. Antiviral assays were performed to determine th. percent of viral inh.bition resulting from treatment with.th. BGE. rOS-GloTM h.sub>2O2 assays were th.n completed to measure th. post-infection rOS levels of BGE-treated virus and cells. Th. results th.s far suggest th.t BGE may inh.bit viral infection and decrease levels of oxidative stress.
