Aim: To detect the parental origin of the extra chromosome 21 in Down syndrome using short tandem repeat (STR) polymorphic markers D21S11, D21S1270, D21S1437.Methods: Three STR (D21S11, D21S1270, D21S1437) loci that were in or near Down syndrome critical region(DSCR) were analyzed and detected by polymerase chain reaction and DNA quantitative analysis in 11 core ancestries.
Methods The review summarizes my hospital to burn the traumatology department for 4 years to admit 43 example burn area to reach 50% above extra heavy burn patient's clinical observation and the nursing countermeasure.
72.6% of Ph negative CML-BC had extra chromosomal abnormalities, with the most common ones being i(17q) and +14. 72.3% of Ph positive CML-BC had extra cytogenetic changes and +Ph, +8, i(17q) were the most frequent.
Fe(1) and Fe(2) are low spin Fe+3, while Fe(3) is high spin Fe+3. Doping of iron brings some extra oxygen atoms that occupy non-Cu-O chains in (001) planes in Y-Ba-Cu-O system. This makes the lattice tend to tetragonal structure.
On the basis of the additive model with the extra constrains of weights, to distinguish whether a decision making unit is DEA efficient (C2R or C2GS2), the extra constrains and distinguishing method in this paper both are different from reference  and .
