The proximal part of the sickle proper displays a clearly demarcated and weakly pronounced heel.
Finally, we have to appreciate that some diagnostic profiles may have selected protective functions, as sickle-cell anemia protects against malaria in tropical climates.
The commonest example here is the link between sickle cell trait and resistance to malaria.
The rest of the plants in the plots were cut with a sickle and then threshed with a stationary thresher.
The technique is being used for gene-based disorders such as sickle cell anemia, thalassemia, and phenylketonuria.
With the exception, in some countries, of thalassemia, sickle-cell anemia, and cystic fibrosis, they account for a small percentage of health-care expenditures.
This is not the case for those who have the sickle cell trait at low altitudes.
However, careful studies are warranted in sickle cell patients given the side effect profile of sulfasalzine, which includes serious gastrointestinal bleeding and nephrotoxicity.
