A study on guinea pigs also highlighted that excess of testosterone during pregnancy can produce hermaphrodites [ 45].
Although no data are available on the responses to gap-in-noise stimuli in the ferret central auditory system, a recent neurophysiological study of guinea pig inferior colliculus found mean neural gap-detection thresholds for single units to be 10.95 ms in response to broadband noise (Berger, Coomber, Wells, Wallace, & Palmer, 2014).
In this regard our results are similar to those from a prior study of guinea-pig atrial myocytes, in which biphasic fade of IKACh occurred with no alteration in Erev for the current [35].
A study of 1,893 adults from Guinea-Bissau conducted between 1998 and 2002 showed lower mortality among vaccinia scar positive individuals more than 20 years after the last vaccinia vaccinations.
In connection with a study of HIV in rural Guinea-Bissau, we assessed vaccinia and BCG scars in 193 HIV-1 or HIV-2 infected and 174 uninfected participants.
In a previous study of the guinea pig model of leptospirosis that compared different routes of infection, the LD50 for subcutaneous injection was twofold higher than with an intraperitoneal bolus, and conjunctival inoculation was yet another three orders of magnitude higher than in subcutaneous infection [29], attesting to the effectiveness of the mucosal barrier.
The epidemiological findings have some biological plausibility as TCDD in experimental studies of guinea pigs, mice and rats decreases cellular glucose uptake [ 4].
When compared at the same concentration in the same phosphate-based CD buffer, all isoforms exhibited differential far-UV absorption from 200 to 245 nm, with discrete minima at 208 222 nm indicative of β-strand and α-helical secondary structure, consistent with previous studies of guinea pig and Dictyostelium Skp1s.
Study groups from Republic of Guinea, Guinea-Bissau, and Malawi were then used in an attempt to replicate this finding [33], [37].
