Aims. To study the origin and characteristics of a bright coronal downflow seen after a coronal mass ejection associated with erupting prominences on 5 March 2000. Methods. This study extends that of Tripathi et al. (2006b) based on the Extreme-ultraviolet Imaging Telescope (EIT), the Soft Xray Telescope (SXT) and the Large Angle Spectrometric Coronagraph (LASCO) observations. We combined those...

The junctional epithelium (JE) adheres to the tooth surface, and seals off periodontal tissues from the oral environment. This incompletely differentiated epithelium is formed initially by the fusion of the reduced enamel organ with the oral epithelium (OE). Two proteins, odontogenic ameloblast-associated (ODAM) and amelotin (AMTN), have been identified in the JE. The objective of this study wa...

The eruption of teeth, like many growth processes, seems to be an orderly and patterned sequence of events. The speed and frequency with which this process occurs make it ideal for studies in development and growth. Yet the interplay of growing tissues that results in eruption, although important, is still a problem. A number of theories have been proposed that attempt to explain the eruptive m...
