Human uterine endometrium undergoes a complex pattern of changes in proliferation and secretory activity during the menstrual cycle. In the present study, telomerase activity in normal endometrium was examined using a non-radioisotope PCR-based telomeric repeat amplification protocol assay. Various levels of telomerase activity were detected in the 60 normal endometrial samples examined, depend...

PURPOSE To investigate the relationship between gap-junction mediated intercellular communication and the proliferative activity of retinal pigment epithelial cells in the retinal tear base. METHODS Retinal tears were created experimentally in white rabbits, and the changes of intercellular communication via gap junctions between retinal pigment epithelial cells in the retinal tear base were in...
