Objective(s): to determine the effect of different doses of caffeine on orthodontic tooth movement (OTM) in rats. Materials and Methods: Forty male 250-300 g Sprague-Dawley rats were randomly divided into four groups of ten animals each and received 0 (control), 1 g/l, 2 g/l and 3 g/l caffeine in tap water for 3 days. Orthodontic appliances were ligated between the maxillary first molars and in...
BACKGROUND Gastric parietal cells in a baboon were recently found to be auto-fluorescent. AIM To study gastric sections with a fluorescent microscope in a cohort of baboons. MATERIAL AND METHODS Gastric sections from 38 baboons were stained with hematoxylin-eosin (H&E) and examined in a fluorescence microscope (FLM). The thickness of the parietal cell population was assessed at x 10 magnifi...

Background: Hirschsprung disease is a complex genetic disorder of the enteric nervous system (ENS), often called congenital aganglionic megacolon and characterized by the absence of enteric neurons along a variable length of the intestine. The definitive diagnosis of Hirschsprung disease relies on histologic and/or histochemical staining of sections fr...
background and objectives: multiple sclerosis is an inflammatory disease of the central nervous system. this is due to migration of peripherally activated lymphocytes to central nervous system leading to inflammatory lesions. however, liver has an anti-inflammatory microenvironment. myelin expression in the liver of transgenic mice suppresses inflammatory lesions within central nervous system. ...
