Deep convective systems occurring near mountains are affected by channeling of airflow near mountains, capping of moist boundary layers by flow subsiding from higher terrain, a...
متن کاملStudies on Non-precipitating Antibody
Reinjection of antigen into immunized rabbits usually results in an immediate increase of circulating antibody-antigen complex. This immediate formation of complex seems to depend upon the presence of non-precipitating antibody before reinjection. The complex disappears by the 2nd day after reinjection and reappears between the 4th to 7th day. This is earlier than its first appearance after a p...
متن کاملPrecipitating factors in pituitary apoplexy.
Pituitary apoplexy is a rare but life threatening condition caused by sudden haemorrhage or infarction of the pituitary gland. Potential precipitating factors in the occurrence of acute pituitary apoplexy in 30 consecutive patients were identified and compared with the clinical characteristics and outcome of patients with and without associated factors. Six patients had a previously known pitui...
