Stable carbon and oxygen isotopes in human tooth enamel: Identifying breastfeeding and weaning in prehistory. Am. J. Phys. Anthropol. 106: 1–18.

ERRATUM: Wright LE and Schwarcz HP (1998) Stable Carbon and Oxygen Isotopes in Human Tooth Enamel: Identifying Breastfeeding and Weaning in Prehistory. Am. J. Phys. Anthropol. 106: 1–18. Isotopic ratios were incorrectly printed as percentages (%) rather than units permil (‰). Wherever “breast feeding” and “breast fed” occur, the words should be combined into “breastfeeding” and “breastfed” respectively. The correct information on isotopic ratios is the following: p. 1, Abstract: all % signs should be “‰”; p. 2, column two, last line: “… δ¹³C values¹, have been …”; p. 2, Footnote 1 should read: “Isotope ratios of carbon and oxygen are expressed in δ notation as follows, δ = [(R_sample/R_standard) − 1] × 1000, where R = ¹³C/¹²C for δ¹³C, and R = ¹⁸O/¹⁶O for δ¹⁸O, and are in units permil, ‰.”; p. 3, column two: all % signs should be “‰”, except for the 23rd line from the bottom, which reads: “… provided 95% of water intake by all infants …”; p. 5: all % signs should be “‰”; p. 6, column one: 8th and 9th line from bottom should be “… mean deviations were 0.029‰ for δ¹³C and 0.024‰ for δ¹⁸O …”; p. 6, column one: 2nd line from bottom should be “… only 0.208‰ for δ¹³C and only 0.091‰ for δ¹⁸O …”; p. 6, column two: top line: “… of 0.5‰ in δ¹³C and 0.2‰ in δ¹⁸O …”; p. 8, 9 and 10: all % signs should be “‰”; p. 11, column two: 7th line from top: “… the lipids are 4-6‰ lighter …”; p. 12, 13 and 14: all % signs should be “‰.”     

Quantitative Comparison of Epstein-Barr Virus Receptor Expression on sIgM and sIgG Cell Lines and B-cell Lymphoma Biopsies

Over 50 B-cell derived lines and B-cell lymphoma and leukemia biopsies were screened for expression of the Epstein-Barr virus (EBV) receptor. The 13 sIgM-positive lines bound more than five times as much virus as the six IgG lines. Among the biopsies, the 17 sIgM, 11 sIgM and sIgD, and seven sIgG expressing biopsies were further divided according to expression of the C3 receptor. C3 receptor-positive biopsies, which expressed sIgM alone or along with sIgD, had the largest subpopulation of cells which expressed the EBV receptor (EBVR). C3 receptor-negative biopsies only expressed the EBVR on half as many cells as their C3 receptor-positive counterparts. However, the relative number of EBVR on individual EBVR-positive cells was independent of C3 receptor expression. Within the sIgG class, both C3 receptor-negative and positive cells expressed equally low levels of EBVR, both in terms of subpopulation and relative number of EBVR per positive cell. These results suggest that subpopulation expression of the EBV receptor is related to the C3 receptor but that relative number of receptors per cell is associated with sIg phenotype.     

ACADEMIC VS. INDUSTRIAL PERSPECTIVES ON SENSORY EVALUATION

The current practice of sensory evaluation occurs in two general settings: the academic environment of a university laboratory and within the foods and consumer products industries. Sensory evaluation programs can differ in orientation, objectives, methodology and context, and viewed from the perspective of Brinberg's tripartite validity theory, focusing on experimental, theoretical and empirical paths. Differences in organizational goals and resources between academia and industry result in different uses of panels, statistics and collaborative efforts. Opportunities for advancement of the field of sensory science exist within the framework of academic training of and industrial demand for sensory professionals.
