Foehn wind 3) Mechanical mixing: When river water passes over rocks, turbulence is generated in the form of rapids, and white water reveals the turbulent mixing of the water with the air above. Similarly, as air passes over mountains, turbulence occurs and the atmosphere is mixed in the vertical. This mixing generally leads to a downward warming and upward moistening of the cross-mountain airflow, and consequently to warmer, drier foehn winds in the valleys downwind. 4) Radiative warming: Dry foehn conditions are responsible for the occurrence of rain shadows in the lee of mountains, where clear, sunny conditions prevail. This often leads
Atelosteogenesis type I Atelosteogenesis type I Atelosteogenesis type I is a rare autosomal dominant condition. This condition is evident at birth and is associated with a very poor prognosis for the baby. It may be diagnosed antenatally. This condition is caused by mutations in the filamin B (FLNB) gene. This gene is located on the short arm of chromosome 3 (3p14). Filamin B forms part of the actin cytoskeleton. How these mutations produce the clinical picture is not yet clear. This is a rare condition with a prevalence of < 1/10. The total number of cases reported to date is <20. Clinical features
