The greater sandhill crane proper initially suffered most; by 1940, probably fewer than 1,000 birds remained. Populations have since increased greatly again. At nearly 100,000, they are still fewer than the lesser sandhill crane, which, at about 400,000 individuals continent-wide, is the most plentiful extant crane. [26] [40]
The major tissues affected are nerves and muscles, where irreversible damage starts to occur after 4–6 hours of cessation of blood supply. [4] Skeletal muscle, the major tissue affected, is still relatively resistant to infarction compared to the heart and brain because its ability to rely on anaerobic metabolism by glycogen stored in the cells may supply the muscle tissue long enough for ...
CDC data shows that whooping cough cases are rising in the U.S. Experts say routine immunization is the best way to prevent the bacterial infection.
Neurogenic claudication must be differentiated from other causes of leg pain, which may be present in a number of conditions involving the spine and musculoskeletal system. The differential diagnosis for NC includes: [9] Vascular claudication; Lumbosacral radicular pain secondary to lumbar disc herniation
