Long-Term Inhalation Toxicity of HydrazineYear-long intermittent exposures of rats, mice, hamsters, and dogs to hydrazine were conducted using concentrations of 0.05, 0.25, 1.0, and 5.0 ppm. Rats were held 18 months postexposure; hamsters, 1 year postexposure; mice, 15 months postexposure; and...

Global climate change (GCC) can negatively affect freshwater ecosystems. However, the degree to which freshwater populations can acclimate to long-term warming and the underlying molecular mechanisms are not yet fully understood. We used the cooling wate
The gene and protein expression of pro apoptotic marker Bax showed a marked increase whereas the anti-apoptotic marker Bcl-2 decreased markedly indicating the aspartame is harmful at cellular level. It is clear that long term aspartame exposure could alter the brain antioxidant status, and can ...
Central or peripheral administration of OXM in rats causes a decrease in short term food intake with minimal effects on gastric emptying (Dakin et al. Endocrinology, 142: 4244-4250 (2001), Dakin et al. Endocrinology, 145: 2687-2695 (2004)). Repeated intracerebroventricular administration of ...
The developing mammalian brain experiences a period of rapid growth during which various otherwise innocuous environmental factors cause widespread apoptotic neuronal death. To gain insight into developmental events influenced by a premature exposure to
thought to form vesicular shapes through a mechanism involving mitochondrial fission. The term “swelling” is also frequently used to describe dysfunctional mitochondria because they show increased permeability of the inner mitochondrial membrane, and the diameter of the vesicular structures also increases ...
3.2. Long-Term Effect of Cu on Anammox Prior the heavy metal exposure, continuous flow system was operated approximately one year and enrichment of the reactor was achieved with 94% nitrogen removal efficiency. Afterward, in order to test the long-term inhibitory effect of Cu on the reactor pe...
Since we have no information about the loss term, we could not differentiate between the fraction of 13C3-glycerol that was used for gluconeogenesis (k1) and the fraction used for other metabolic pathways (kL), such as glycolysis or triglyceride synthesis. Instead, we summed the rate constant...
