Network Structure and the Efficiency Gains from Mergers: Evidence from U.S. Freight Railroads
ABSTRACT The trade‐off between market power and efficiency gains is central to antitrust analyses of mergers, but empirical evidence quantifying efficiencies remains limited. Using transaction‐level data from U.S. freight railroads (1985–2005), this article quantifies merger‐induced cost efficiencies, driven mainly by eliminating inter‐railroad ...

This study investigates the role of ER stress in steroid resistance in severe asthma. Results from advanced 3D models of human bronchial epithelial cells, steroid‐resistant severe asthma mouse models, and human severe asthma sputum samples show that treatment with ICS in combination with the ER stress inhibitor 4‐PBA significantly enhances steroid ...

High‐dose birch‐extract nasal challenge induced synchronous peaks at 4 weeks in serum specific IgE (sIgE) and basophil sensitivity. Mast cell sensitivity via tSPT and sIgG1 and sIgG4 responses peaked later, at 6–8 weeks. Preseasonal allergen exposure attenuated seasonal sIgE increase and prevented further rise in tSPT sensitivity.
