Otitis media needle aspiration through the tympanic membrane to relieve the ear pain and to identify the causative organism(s). Children with recurrent episodes of acute otitis media and those with otitis media with effusion or chronic suppurative otitis media have higher risks of developing conductive and sensorineural hearing loss. Globally approximately 141 million people have mild hearing loss due to otitis media (2.1% of the population). This is more common in males (2.3%) than females (1.8%). This hearing loss is mainly due to fluid in the middle ear or rupture of the tympanic membrane. Prolonged duration of otitis media is associated with
Plasma membrane Ca2+ ATPase to involve the lymph nodes, and are more common among young women, which could help explain their worse prognosis compared with postmenopausal women. PMCAs were first discovered in the 1960s in the membranes of red blood cells. The presence of an ATPase was discovered in the membranes in 1961, and then in 1966 it was discovered that these ATPases pump Ca out of the cytosol. PMCA was first purified from red blood cell membranes in 1979. Plasma membrane Ca2+ ATPase The plasma membrane Ca ATPase (PMCA) is a transport protein in the plasma membrane of cells and functions to remove
