A pro-diabetic diet triggers early functional and structural changes in the rat retina
International audience; Purpose : Diabetic retinopathy (DR) is the leading cause of blindness in industrial countries before the age of 50 years. The early consequences of diabetes on the retina are nevertheless poorly known. We therefore aimed at characterizing the early effects of a high fructose and high fat diet on the function and structure of the rat retina. Methods : Male Brown Norway rats (6 weeks of age) were fed for 8 days (n=16), 4 weeks (n=16) and 12 weeks (n=8) with 60% fructose+10% lipid rich diet (HFHF), or a standard chow (n=8). At each time point, intraperitoneal insulin tolerance test (ITT-0.5 U/ml) and intraperitoneal glucose tolerance test (GTT-2g/kg body weight) were ca…

Oral homeostasis disruption by medical plasticizer component bisphenol A in adult male rats.
Objectives/Hypothesis Bisphenol A (BPA) is a synthetic estrogen-like chemical mimetic widely used in the manufacture of polycarbonate plastics and epoxy resins found in numerous consumer products including food packaging, medical devices, and dental sealants. Because it is recovered in fluids and it can reach high levels in saliva, this study aimed to evaluate its safety on oral homeostasis by examining its effects on salivary glands, mouth epithelium, water consumption, and salt preference, each parameter being estrogen sensitive. Study Design Randomized controlled trial involving rats. Methods A dose-response study was conducted in adult Wistar rats randomized into five groups (n = 12). B…

A multi-generational study on low-dose BPA exposure in Wistar rats: Effects on maternal behavior, flavor intake and development
Bisphenol A (BPA) is a common endocrine disruptor found as an environmental and food contaminant. It exerts both developmental and behavioral effects, mainly when exposure occurs in early life. The aim of this study was to determine the multi-generational effects of chronic, human-relevant low-dose exposure to BPA on development, maternal behavior and flavor preference in Wistar rats. BPA was orally administered at a daily dose of 5 mu g/kg body weight to FO pregnant dams from the first day of gestation (GD 1) until the last day of lactation (LD 21), and then to Fl offspring from weaning (PND 21) to adulthood (PND 100). F2 offspring were not exposed. Development and clinical signs of toxici…
