The hippocampus supports several important cognitive functions known to undergo substantial development during childhood and adolescence, for example, encoding and consolidation of vivid personal memories. However, diverging developmental effects on hippocampal volume have been observed across studies. It is possible that the inconsistent findings may attribute to varying developmental processe...
Intracerebroventricular administration of corticotropin-releasing hormone (CRH) elicits a constellation of behavioral, autonomic, and endocrinological changes typically observed in stress. One of the behavioral changes after intracerebroventricular CRH is a profound increase of startle amplitude (CRH-enhanced startle). The present study examined the role of the septum in CRH-enhanced startle. T...
Type 1 fimbriae are the most commonly expressed virulence factor on uropathogenic Escherichia coli. In addition to promoting avid bacterial adherence to the uroepithelium and enabling colonization, type 1 fimbriae recruit neutrophils to the urinary tract as an early inflammatory response. Using clinical isolates of type 1 fimbriated E. coli and an isogenic type 1 fimbria-negative mutant (CN1016...
In a previous study we used the species-specific marker M6 to demonstrate that transplanted mouse embryonic hippocampal neurons grow axons at a rate of at least 1 mm/d for a distance of at least 10 mm along the longitudinal axis of the fimbria in immunosuppressed adult rat hosts. We now show that hippocampal neurons are able to grow comparably long interfascicular axons in two other myelinated ...
The DNA sequence determination of the f1 operon between the genes encoding the F1 subunit (caf1) and chaperone-like protein (caf1M) revealed a large open reading frame that codes for a polypeptide similar to some E. coli proteins involved in the biogenesis of fimbria. The deletion and in trans complementation analyses showed that this gene is not necessary for extracellular transport of the F1 ...
We isolated a Bacillus sp. strain that could display broad-spectrum biofilm inhibition. The broad biofilm prevention could be achieved mainly by direct contact between inhibitor and target cells or was accompanied by an interaction with secreted inhibitory compounds. The repression of cell surface fimbria-like appendages of a biofilm producer was also observed; this was considered to contribute...
