2. transcription activation domain(English)

   • FIH, HIF
   • Transcription

4. thoracic aortic dissection(English)

   • estimated to occur at a rate of 3-4 cases per 100,000 persons per year and is associated with a high mortality
   • SRC

5. tip apex distance(English)

   • should be less than 25 mm to prevent DHS cut-out or failure, which most often happens if the screw is placed too anterior or too superior. The TAD is the sum of the distance from the tip of the screw to the apex of the femoral head on AP and lateral views. Fractured neck of femur is a common problem seen in elderly osteoporotic females, mostly in Western countries, among which are the extra-capsular fractures such as intertrochanteric and pertrochanteric fractures also known as peritrochanteric fractures, and commonly treated with dynamic hip screw (DHS) or compression hip screw (CHS)
