rodgers (rg) and chido (ch) are blood-group antigens and they determine the fourthcomponent of human complement c4. rodgers and chido are associated with two c4 isotypes (c4a and c4b). in addition to genotype determination, study on expression of rg and chido could be useful in disease studies. dna was extracted from the whole blood of 60 normal individuals. then, pcr amplification of c4d gene ...

Although there have been studies of AM in Brazil and the Russian Federation using different definitions and age cohorts, this indicator has never been used to compare these cities. During the period 2000–10, age-adjusted rates of all leading causes of AM fell in all three ci...
