Review[The molecular basis of RH system and its applications in obstetrics and transfusion medicine].
The Rh system is the most polymorphic and immunogenic for all blood group systems. Currently more than 49 antigens were identified with five major antigens D, C, c, E, e. ⋯ In Caucasians the primary mechanism of Rh-negative phenotype is the complete RHD gene deletion, while in African descendants it is the presence of pseudogene and gene RHDψ hybrid RHD-CE (4-7)-D. The authors analyze the structure of the Rh complex in red cells, molecular basis of the Rh system, mechanisms of Negativity RHD and weak and incomplete expression of RHD.

[Physical activity in the prevention of diabetes in black ethnicity: how much is required?].
Analyze how much total physical activity (intensity and duration) is required and its different domains (work, commuting, household, and leisure time) as predictors of absence of diabetes in the black ethnicity population. ⋯ Physical activity accumulated in different domains should be suggested in amounts suitable for a black ethnicity population in order to contribute to diabetes prevention.
