In conclusion, we found a gradient of increasing blood pressure with higher levels of BMI. The fact that this gradient is present even in the fully adjusted analyses suggests that BMI may cause a direct effect on blood pressure, independent of other clinical risk factors. PRRX1 as a Possible Point of Control for Remyelination https://www.fightaging.org/archives/2018/12/prrx1-as-a-possible-point-of-control-for-remyelination/ Researchers here outline what is possibly a new point of intervention in the processes that maintain the myelin sheath that wraps nerves. This sheath is vital to the correct operation of the nervous system, and as a consequence demyelinating conditions such as multiple sclerosis are unpleasant and fatal. Loss of myelin isn't just restricted to named conditions, however: some degree of degradation occurs over the course of aging, and is thought to contribute to the progression of cognitive decline. Thus therapies that can boost myelin maintenance may be of greater interest than it might at first appear. Myelin is maintained by oligodendrocyte cells, and the slow disruption of this cell population and its maintenance activities is the major cause of issues in aging. All cell populations exhibit loss of effectiveness or pathological behavior with the rising levels of inflammation and molecular damage present in older individuals. This research suggests a novel way to attempt to override the cellular reactions to the damage of aging...
