Making mature attachments
The death stops here lants rely on a sensitive process of programmed cell death to curtail pathogenic infection by selectively executing infected cells. To prevent the death response from spreading to noninfected areas, cells near and at the site of infection activate autophagy, say and colleagues. In virus-infected plants that are unable to turn on autophagy, cell death spreads from the site o...
متن کاملMagnetic Attachments
This study investigated the effect of heat history on the eorrosion of keepers used for dental magnetic attachments. Ferritic stainless steels of SUS 444 and 447Jl were prepared with heat treatments in the temperature range of 550-850°C for 1-5 hours. The stainless steels were electrochemically and metallurgically examined by anodic polarization curves in a O.9% NaCl solution and by microstruct...

متن کاملMaking neurons from mature glia: a far-fetched dream?
The fact that cells with glial characteristics such as forebrain radial glia during development and astroglial stem cells in the adult neurogenic zones serve as neuronal precursors provokes the question why glia in most other areas of the adult central nervous system are apparently incapable of generating new neurons. Besides being of pivotal biological interest answers to this question may als...
متن کاملRepeatable Collaboration Processes for Mature Organizational Policy Making
Organizational policy making processes are complex processes in which many people are involved. Very often the results of these processes are not what the different stakeholders intended.
