The hazardous involvement of environmental compounds in the pathogenesis of OGCT remains a hypothesis but was recently supported by a rat study showing transgenerational epigenetic inheritance and altered phenotypes of pubertal onset and gonadal disease in the third generation after exposure to compounds such as plastics, dioxins, hydrocarbons, and pesticides (122).
Rat studies showed that perfluorinated compounds (PFCs) cause significantly increase in mammary fibroadenomas.
Laboratory rat studies showed elevated levels of 8-OHdG in urine following exposure to DBP or butyl benzyl phthalate (BzBP) and mBP; nevertheless, a significant positive relationship was only found between urinary 8-OHdG and mEHP or miBP levels in our study.
Additional rat studies showed that the gas phase alone was not acutely toxic and that aging of the PTFE fume particles for 3 min increased their particle size to > 100 nm because of accumulation, which resulted in a loss of toxicity (Johnston et al. 2000).
In vivo rat studies show complete graft patency at all time points, rapid endothelialization, and stabilization and contraction of neointimal hyperplasia.
In vivo rat studies show that HAMC is biocompatible within the intrathecal space for 1 month, and may provide therapeutic benefit, in terms of behavior, as measured by the Basso, Beattie and Bresnahan (BBB) locomotor scale, and inflammation.
Rat studies show that the development of low-grade inflammation negatively affects muscle mass and attenuates the muscle protein synthesis response to feeding [ 4, 5].
This view is supported by recent rat studies showing that areas 29 and 30 jointly support the same overall classes of learning, e.g., spatial memory, but make different contributions (van Groen et al., 2004; Vann and Aggleton, 2005; Pothuizen et al., 2009, 2010).
In contrast to a previous study [7] indicating that the expression of 5-HT3 receptors by trigeminal ganglion neurons innervating the masseter muscle was higher in female rats, this study showed no significant difference in the expression of 5-HT3A receptors in the masseter or tibialis muscles, when men and women were compared.
The TDCs from 8 rats in our study showed an arterial enhancement peak at 2 s.
