Targeting PI3K/Akt/mTOR signaling in rodent models of PMP22 gene-dosage diseases.

Haplo-insufficiency of the gene encoding the myelin protein PMP22 leads to focal myelin overgrowth in the peripheral nervous system and hereditary neuropathy with liability to pressure palsies (HNPP). Conversely, duplication of PMP22 causes Charcot-Marie-Tooth disease type 1A (CMT1A), characterized by hypomyelination of medium to large caliber axons. The molecular mechanisms of abnormal myelin growth regulation by PMP22 have remained obscure.

Headache Is Associated with Low Systolic Blood Pressure and Psychosocial Problems in German Adolescents: Results from the Population-Based German KiGGS Study.

Studies have reported controversial results on the relationship between headache and blood pressure. The aim of this post hoc study was twofold: first, to further investigate this relationship and, second, to assess the impact of psychosocial factors on this association in a population-based study of German children and adolescents. The analysis was conducted on study participants aged between 11 and 17 years ( = 5221, weighted from the total study cohort) from the nationwide German Health Interview and Examination Survey for Children and Adolescents (KiGGS).
