Although diversity within the HLA-DRB region is predominantly focused in the DRB1 gene, the second expressed DRB loci, DRB3, DRB4, and DRB5, also exhibit variation. Within DRB1(*)15 or DRB1(*)16 haplotypes, four new variants were identified: 1) two new DRB5 alleles, DRB5*0104 and DRB5*0204, 2) a haplotype carrying a DRB1(*)15 or *16 allele without the usual(More)
The limited amino acid sequence differences between the DR3 microvariants, DRw17 and DRw18, are found in the second variable region of the DR beta chain (residues 26 and 28) as well as in framework residues 47 and 86. Using selected responder/stimulator combinations, alloproliferative T-lymphocyte clones (TLC) were generated which recognize either a(More)
The frequencies of 30 HLA-DRB1*13 alleles and 15 DRB3 alleles were determined for the 5 major U.S. ethnic populations: Caucasians, African Americans, Asian/Pacific Islanders, Hispanics, and Native Americans. A random sampling (163) of DRB1*13-positive individuals from each self-described ethnic group was selected out of a pool of 82,979 unrelated(More)
A Web based remote monitoring & controlling method for heat exchange system is presented in this paper. Under Internet/Intranet environment, the CAN bus technology, the embedded WEB sensor and the popular B/S structure are used to realize the remote monitoring & controlling of the heat exchange system, so it can overcome the shortage of the C/S structure,(More)
The National Marrow Donor Program (NMDP) has instituted an approach to address the impact of new alleles on the DNA-based HLA assignments obtained during volunteer donor typing. This approach was applied to the DRB typing results from 371,187 donors received from 14 laboratories in 1999. Samples were tested with a standardized set of sequence specific(More)
The frequencies of alleles in the HLA-DRB1*01 family were determined in each of five US populations from a database of 82,979 individuals. Individuals typed as DR1 (or DRB1*01) comprised between 7.6%-21.3% of the individuals in each population group. Fifty-nine DR1 individuals were randomly selected from each group and subjected to high-resolution DNA(More)
During 2005, a total of 174 cord blood units with their paired maternal samples from the Singapore Cord Blood Bank were typed for HLA-A, -B, -C at intermediate resolution and DRB1 at allelic resolution. Analysis of allele segregation in mother and child assigned 185 different four locus (HLA-A, -B, -C, -DRB1) haplotypes in Chinese, 66 in Malays, and 34 in(More)
A dwell scheduling model which takes the time and energy constraints into account is founded from the viewpoint of scheduling gain. Dwell scheduling strategy design is turned into a nonlinear programming procedure. A dwell scheduling algorithm is then given based on the genetic algorithm. Simulation results demonstrate that compared with the conventional(More)
