An estimated 15 to 20 percent of researchers who work with mice and rats, for instance, may eventually become allergic to the animals, said Dr. Karin A. Pacheco, an assistant professor of environmental and occupational health sciences at National Jewish Health in Denver.
It's not clear why cancer rates rose in male but not female rats, for instance, or why rats exposed to cellphone radiation lived, on average, longer than radiation-free rats.
Though this type of co-localization of GS and GFAP was preserved in other skin samples of adult rats, for instance in leg skin (Figure 4G L), the ratio between GS (green) and GFAP (red) seemed to vary slightly depending on whether samples from lateral (Figure 4G I) or medial (Figure 4J L) leg skin were stained.
In adult rats, for instance, exogenous TH increases immunoreactivity for the cell proliferation marker Ki-67 in the subventricular zone of the brain (Giardino et al. 2000).
Sex differences in ethanol intake may begin to emerge during adolescence (Truxell et al., 2007), a developmental period characterized by elevated ethanol consumption in both humans and laboratory rodents, with adolescent rats, for instance, exhibiting 2- to 3-fold higher ethanol intake than their adult counterparts (Brunell and Spear, 2005; Doremus et al., 2005; Vetter et al., 2007).
In rat study, for instance, the animals were fed levels of oxybenzone that would never be achieved in humans through normal exposure to sunscreen.
These are fine if you're adept at spur-of-the-moment currency conversions and foreign-language translations, but if you cannot for some reason decipher the Italian phrase meaning "occasional rat problems," for instance, such Web sites can pose problems.
