This study investigates whether low maternal education is associated with overweight and obesity risk in children from distinct European settings during early childhood. Prospective data of 45 413 children from 11 European cohorts were used. Children's height and weight obtained at ages 4-7 years were used to assess prevalent overweight and obesity according to the International Obesity Task Force definition. The Relative/Slope Indices of Inequality (RII/SII) were estimated within each cohort and by gender to investigate adiposity risk among children born to mothers with low education as compared to counterparts born to mothers with high education. Individual-data meta-analyses were conducted to obtain aggregate estimates and to assess heterogeneity between cohorts. Low maternal education yielded a substantial risk of early childhood adiposity across 11 European countries...

There is limited combined evidence on inequalities in health among newborns across a range of European countries. Prospective cohort data of 75 296 newborns from 12 European countries were used. Maternal education, preterm and small for gestational age births were determined at baseline along with covariate data. Regression models were estimated within each cohort and meta-analyses were conducted to compare and measure heterogeneity between cohorts. Mother's education was linked to an appreciable risk of preterm and small for gestational age (SGA) births across 12 European countries. The excess risk of preterm births associated with low maternal education was 1.48 (1.29 to 1.69) and 1.84 (0.99 to 2.69) in relative and absolute terms (Relative/Slope Index of Inequality, RII/SII) for all cohorts combined. Similar effe...
Ultrastructural, functional, and cytochemical characteristics of resident sinusoidal macrophages ... more Ultrastructural, functional, and cytochemical characteristics of resident sinusoidal macrophages (RSM) in brown bullhead (Ictalurus nebulosus) liver were examined. Following perfusion fixation of the hepatic vascular bed, light micrographs revealed RSM that possessed multiple elongate cytoplasmic processes and frequently contained erythrocytes in various stages of degradation. Following brief perfusion fixation, light microscope examination of vibratome sections of bullhead liver reacted for peroxidase revealed intensely positive RSM. By transmission electron microscopy, peroxidase activity was localized to the nuclear envelope and cytoplasmic granules of RSM and in endothelial and perisinusoidal fat-storing cells. In cryostat sections of fresh-frozen liver, glucose-6-phosphate dehydrogenase (G-6-PDH) was uniformly distributed over hepatocytes, whereas intensely positive punctate staining for G-6-PDH was localized over RSM. To test for phagocytosis by RSM, latex beads (0.81 micron) ...

The environment might also explain much of the previously unexplained imbalance of phylogenetic trees. We use data on geographic distribution and phylogenetic affinity to examine correlates of species richness among genera of irises (family: Iridaceae). Irises display strong phylogenetic imbalance, with a few clades containing a disproportionate number of species, most notably those found in the dry Mediterranean climate of the Cape of South Africa. The abiotic environment and area are strong predictors of iris species richness, but environment alone is insufficient to explain the high diversity of Cape clades. One possible explanation is that the interaction between biological traits and environment resulted in the unusually high diversification rates in the region.
