Killer immunoglobulin like receptor gene profiling in Western Indian population

One hundred and sixty one healthy unrelated hematopoietic stem cell transplant donors from Western Indian were enrolled in this study. The study was initiated to observe the genotypic diversity of 16 killer immunoglobulin like receptor (KIR) genes in this population. KIR genotyping was carried out using the PCR-SSP technique. 56 KIR genotypes were observed in our population, where 15 genotypes were reported for the first time in any population. The KIR genotype data for the population can be accessed from Allele Frequencies Net Database under the population name “India Western KIR” and identifier “3570”.     

Relationship between arm span and stature in Malawian adults

OBJECTIVE: The aim of this cross-sectional study was to assess the relationship between height and arm span in adult Malawians. SUBJECTS AND METHODS: 142 males and 128 females between the ages 20 and 76 years were recruited from among the patients attending various clinics at Queen Elizabeth Central Hospital, Blantyre, Malawi. All subjects were free from physical deformities. The anthropometric measurements included standing height and arm span. RESULTS: The arm span exceeded height in all age groups of males and females. The mean difference between the height and arm span values for females was 9.9 +/- 4.9 cm (t = 16.28, p<0.001) and for males was 11.6 +/- 4.4 cm (t = 14.74, p<0.001). The gender difference between height and arm span measurements was statistically significant (t = 9.58, p<0.001 and t = 10.24, p<0.001, respectively). Correlation of arm span and height for males was 0.871 and for females was 0.815. Prediction equations were derived from regression analysis. RSD values were 8.709 and 6.914 for equations for males and females, respectively. CONCLUSIONS: Stature of Malawian adults can be estimated from arm span measurements using regression equations.

All subjects were free from physical deformities. The anthropometric measurements included standing height and arm span.

Results: The arm span exceeded height in all age groups of males and females. The mean difference between the height and arm span values for females was 9.9 ± 4.9?cm (t = 16.28, p<0.001) and for males was 11.6 ± 4.4?cm (t = 14.74, p<0.001). The gender difference between height and arm span measurements was statistically significant (t = 9.58, p<0.001 and t = 10.24, p<0.001, respectively). Correlation of arm span and height for males was 0.871 and for females was 0.815. Prediction equations were derived from regression analysis.

Conclusions: Stature of Malawian adults can be estimated from arm span measurements using regression equations.     

Killer cell immunoglobulin-like receptor genotypes in a Chilean population from Talca

Ninety healthy and unrelated volunteers were randomly selected to study the gene frequencies of Killer-cell immunoglobulin-like receptors (KIRs) in a Chilean (Talca) population. KIR typing was resolved by PCR-single specific primer (SSP), and their gene frequencies were calculated by direct counting of the number of positive and negative loci. The KIR genotype data is publicly available in the Allele Frequencies Net Database under the name “Chile Talca KIR”.
