Books in Arabic Script
The chapter approaches the book in Arabic script as the indispensable means for the transmission of knowledge across Eurasia and Africa, within cultures and across cultural boundaries, since the seventh century ad. The state of research can be divided into manuscript and print studies, but there is not yet a history of the book in Arabic script that captures its plurilinear development for over fourteen hundred years. The chapter explores the conceptual and practical challenges that impede the integration of the book in Arabic script into book history at large and includes an extensive reference list that reflects its diversity.
The final published version was slightly updated, and includes seven illustrations of six Qurans from the holdings of Columbia University Libraries, four manuscripts and two printed versions. Moreover, the illustrations are images of historical artifacts which are in the public domain - despite Wiley's copyright claim
Metabolic profiling detects early effects of environmental and lifestyle exposure to cadmium in a human population
Background: The ‘exposome’ represents the accumulation of all environmental exposures across a lifetime. Topdown
strategies are required to assess something this comprehensive, and could transform our understanding of
how environmental factors affect human health. Metabolic profiling (metabonomics/metabolomics) defines an
individual’s metabolic phenotype, which is influenced by genotype, diet, lifestyle, health and xenobiotic exposure,
and could also reveal intermediate biomarkers for disease risk that reflect adaptive response to exposure. We
investigated changes in metabolism in volunteers living near a point source of environmental pollution: a closed
zinc smelter with associated elevated levels of environmental cadmium. Methods: High-resolution 1H NMR spectroscopy (metabonomics) was used to acquire urinary metabolic profiles
from 178 human volunteers. The spectral data were subjected to multivariate and univariate analysis to identify
metabolites that were correlated with lifestyle or biological factors. Urinary levels of 8-oxo-deoxyguanosine were
also measured, using mass spectrometry, as a marker of systemic oxidative stress. Results: Six urinary metabolites, either associated with mitochondrial metabolism (citrate, 3-hydroxyisovalerate, 4-
deoxy-erythronic acid) or one-carbon metabolism (dimethylglycine, creatinine, creatine), were associated with
cadmium exposure. In particular, citrate levels retained a significant correlation to urinary cadmium and smoking
status after controlling for age and sex. Oxidative stress (as determined by urinary 8-oxo-deoxyguanosine levels)
was elevated in individuals with high cadmium exposure, supporting the hypothesis that heavy metal
accumulation was causing mitochondrial dysfunction. Conclusions: This study shows evidence that an NMR-based metabolic profiling study in an uncontrolled human
population is capable of identifying intermediate biomarkers of response to toxicants at true environmental
concentrations, paving the way for exposome research.

A History of Universalism: Conceptions of the Internationality of Science from the Enlightenment to the Cold War
That science is fundamentally universal has been proclaimed innumerable times. But the precise geographical meaning of this universality has changed historically. This article examines conceptions of scientific internationalism from the Enlightenment to the Cold War, and their varying relations to cosmopolitanism, nationalism, socialism, and 'the West'. These views are confronted with recent tendencies to cast science as a uniquely European product
