BACKGROUND Non-nutritive sweeteners (NNS) have been associated with increased prevalence of obesity. In previous studies, we demonstrated that saccharin could induce an increase in weight gain either when compared to sucrose or to a non-sweetened control at a similar total caloric intake. These data raised the hypothesis that reduced energy expenditure (EE) could be a potential mechanism explai...

Background: Chronic ethanol abuse causes reproductive organ failure and infertility in both humans and laboratory animals. Since sperm has a critical role in reproductive function, the objective of this unique study was to evaluate the effects of different doses of ethanol on sperm parameters, chromatin structure and apoptosis in adult mice. Materials and Methods: A total of 36 adult male mice ...

The ability to predict harmful effects of chemicals, drugs, and food additives has historically depended on the process of extrapolating from animal studies. The current guidelines of the U.S. Food and Drug Administration recommend nine animalbased studies to assess the safety of additives used directly in food handling or preparation or at the table in amounts in excess of 1 part per million i...

In this study the effect of crystallite size reduction and microstructure on the electrochemical corrosion behavior of nanocrystalline nickel (NC Ni) were investigated using Tafel polarization and electrochemical impedance spectroscopy (EIS) measurements in 10 wt.% NaOH. NC Ni coatings were produced by direct current electrodeposition using chloride baths in presence and absence of saccharin as...

Cohort analyses of bladder cancer mortality rates in men and women in England and Wales have been compared with figures for the per caput consumption of saccharin and cigarette tobacco and with similar analyses of cigarette smoking habits. The increase in bladder cancer mortality rates in male cohorts born since 1870 can be attributed to cigarette smoking, and there is no evidence of any break ...

The present experiment examined the influence of excitotoxic lesions of the basolateral amygdala (BLA) on morphine-induced saccharin avoidance. Neurologically intact subjects rapidly learned to avoid drinking the taste conditioned stimulus (CS), an effect that was sustained throughout the experiment. Although the BLA-lesioned (BLAX) rats showed CS avoidance over the first few trials, the effect...
