Prevalence of antibodies interactive with HTLV‐I antigens in selected Solomon Islands population
Serum samples obtained in 1986 from healthy individuals in three distinct Solomon Islands populations were screened for antibodies to human lymphotropic virus type I (HTLV‐I). One of the populations tested lives on the remote Polynesian outlier atoll, Ontong Java. The other two groups, the Baegu and the Lau, are Melanesians living on Malaita, the most populous of the larger Solomon Islands. Eighty‐eight of a total of 601 (14.6%) sera tested were …
Analysis of hair samples of mummies from Semna South (Sudanese Nubia)
Hair samples from 76 burials at Semna South (Sudanese Nubia) were examined using a variety of techniques. Electrophoresis and fluorescence microscopy indicated some oxidation of the cuticule and keratin protein had taken place. However, the cuticular structure and the lack of fluorescence of the cortex indicate that the low humidity and non‐alkaline conditions preserved the physical and chemical properties of the hair well. Pigmentation, even all…
Biochemical variation of hair keratins in man and non‐human primates
Human hair from various racial groups was investigated using the following techniques: amino acid analysis, acrylamide gel electrophoresis, x‐ray diffraction studies, stress‐strain analysis. Each of these techniques yielded identical results for all samples, indicating that the variables producing phenotypic differences in human hair form are probably not on the level of primary or secondary biochemical structure. Hair samples of a variety of pri…
Quantitative hair form variation in seven populations
Although hair form has received much attention in the past, it has rarely been studied systematically, and never using direct curling variables. In the present study, seven groups were scored on eight variables, including four newly‐devised curling variables. These data were analyzed using univariate and multivariate techniques to give information about the population relations and mechanisms of hair form. “Racial” groups were separated using a p…
