By using pigs sensitized to bovine serum albumin (BSA), it was found that exposure of the intestinal mucosa to BSA induced, in 4 h, the emigration of large numbers of neutrophils into the intestinal lumen. This response was specific for the immunizing antigen and could be transferred to nonimmune animals with immune serum. The emigration of neutrophils through the intestinal mucosa was not acco...

Recent concern over global amphibian population declines has highlighted a need for more extensive, rigorous monitoring programs. Two sources of variation, spatial variation and variation in detection probability, make the design and implementation of effective monitoring programs difficult. We used Pollock’s robust design in a 3-year capture–recapture study to estimate detection probability an...

Local edema, a cardinal sign of inflammation associates closely with neutrophil emigration. Neutrophil emigration has been described to occur primarily through endothelial junctions (paracellular) and more rarely directly through endothelial cells (transcellular). Recently, we reported that unlike in wild-type (wt) mice, Mac-1-/- (CD11b) neutrophils predominantly emigrated transcellularly and w...

To investigate the requirements for adhesion molecules in neutrophil emigration during peritonitis, mice received intraperitoneal injections of Streptococcus pneumoniae while the functions of multiple adhesion molecules were blocked. Emigration after 4 h was compromised by antibodies against ICAM-1 or genetic deficiency of ICAM-1. Anti-CD11a/CD18 antibodies decreased emigration in ICAM-1 mutant...

Anthropogenic stress on natural systems, particularly the fragmentation of landscapes and the extirpation of predators from food webs, has intensified the need to regulate abundance of wildlife populations with management. Controlling population growth using fertility control has been considered for almost four decades, but nearly all research has focused on understanding effects of fertility c...

This paper presents a cross country empirical investigation of impacts of skilled labor emigration on sending country’s institutional development. Based on Albert Hirschman’s “Exit and Voice” model, we analyze different channels through which emigration can affect institutions; using Djankov et al.’s “Institutional Possibility Frontier” framework, we assess emigration’s heterogeneous effects on...
