Background

IFN-α is a cytokine that has an immunomodulatory function. It plays an important role not only in antiviral activity but also in several physiologic functions, such as activation of dendritic cells and accelerated expression of major histocompatibility complex I and II molecules that may cause increased antigen presentation. Variants of human leukocyte interferon α 2 (IFN-α 2a, α 2b, and α 2c) differ from each other by changes in their coding regions at nucleotide positions 137 and 170. IFN-α 2a is an important cytokine and used for antiviral and anticancer treatment.

The Perfect Digital Watch with all the Bells & Whistles!
Color: Black/Gray
I always buy this kind of watch, and so does my adult daughter. It has a timer, 3 alarm settings, push button light, easy to set, and other features that I don't use, like, track timers, Occasion settings, Beeps & Chimes, On or Off. I use it for timing my Laundry, taking pills, timing things in the kitchen. I just can't live without it! My daughter used it for timing on her Breast Feeding Schedule, so no matter what room she was in, or what she was doing, she would always hear that alarm!
