1. The permeability of the human erythrocyte to anions has been measured under conditions of net charge transfer: for Cl(-) and HCO(3) (-) ions, at 37 degrees C, this permeability is 5 orders of magnitude too small to account for the rate of the electroneutral anion exchange which is responsible for the chloride, or Hamburger, shift.2. The method is an(More)
Recombinant calprotectin, consisting of 2 individual peptide chains also called migration inhibitory factor-related protein (MRP)-8 and MRP14, was tested for antimicrobial activity in a Candida albicans growth inhibition assay. Both chains contain HEXXH zinc-binding sites and might be expected to manifest zinc-reversible, antimicrobial activity similar to(More)
The sagittal vestibulocollic reflex (v.c.r.) evoked by nose-up, nose-down movements of the head, has been studied in the neck extensor muscle biventer cervicis in the decerebrate cat. Nose-down movements of the head increased, and nose-up movements decreased, electromyographic (e.m.g.) activity in the biventer cervicis muscles of the left and right sides.(More)
The phenotypical and functional heterogeneity of different macrophage subpopulations are defined by discrete changes in the expression of two S100 calcium-binding proteins, migration inhibitory factor-related proteins (MRPs) 8 and 14. To further our understanding of MRP8 and MRP14 in the developmental stages of inflammatory responses, overexpression of the(More)
The cytoplasmic N-terminal domain of the human ether-a-go-go related gene (hERG) K+ channel is critical for the slow deactivation kinetics of the channel. However, the mechanism(s) by which the N-terminal domain regulates deactivation remains to be determined. Here we show that the solution NMR structure of the N-terminal 135 residues of hERG contains a(More)
Canine leukocyte adhesion deficiency (CLAD) provides a unique large animal model for testing new therapeutic approaches for the treatment of children with leukocyte adhesion deficiency (LAD). In our CLAD model, we examined two different fragments of the human elongation factor 1alpha (EF1alpha) promoter (EF1alphaL, 1189 bp and EF1alphaS, 233 bp) driving the(More)
The N-terminal cytoplasmic region of the Kv11.1a potassium channel contains a Per-Arnt-Sim (PAS) domain that is essential for the unique slow deactivation gating kinetics of the channel. The PAS domain has also been implicated in the assembly and stabilization of the assembled tetrameric channel, with many clinical mutants in the PAS domain resulting in(More)
