Lipids are major structural component of the brain and play key roles in signaling functions in the central nervous system (CNS), such as the hippocampus. In particular, sulfatide is an abundant glycosphingolipid component of both the central and the peripheral nervous system and is an essential lipid component of myelin membranes. Lack of sulfatide is observed in myelin deformation and neurological...
Methods to study gene expression in live cells over time have been limited. One known method is the luciferase assay, which measures the luminescence of luciferase by coupling its expression to the promoter of a gene under study. This luminescence in cells can be measured over time by a luminometer. One major drawback of the luminometer, however, is that it can only measure the luminescence of a group...
Recently, prolactin was shown to inhibit the development of stress-induced ulcers. However, the mechanism for suppression of gastric ulcers by prolactin has not been clarified. Hatano high-avoidance (HAA) and low-avoidance (LAA) strains of rats were originally selected and bred from Sprague-Dawley rats based on shuttle-boxtasks. The present study focused on the relationships among gastric ulceration...
The high- and low-avoidance animals (HAA and LAA rats) were originally selected from Sprague-Dawley rats for their shuttle-box task. Reproductive endocrinology during the estrous cycle was compared between HAA and LAA rats. All HAA rats showed a regular 4-d estrous cycle, whereas most LAA rats (70.8%) showed a regular 5-d estrous cycle. The peak level of preovulatory luteinizing hormone (LH) surge...
