Cavitation of xylem elements diminishes the water transport capacity of plants, and quantifying xylem vulnerability to cavitation is important to understanding plant function. Current approaches to analyzing hydraulic conductivity (K) data to infer vulnerability to cavitation suffer from problems such as the use of potentially unrealistic vulnerability… (More)
BACKGROUND INFORMATION Many neurons secrete classical transmitters from synaptic vesicles as well as peptide transmitters from LDCVs (large dense-core vesicles). Little is known about the mechanistic differences between these two secretory pathways. The soluble protein Munc18-1 is essential for synaptic vesicle secretion [Verhage, Maia, Plomp, Brussaard,… (More)
In mammals, the synaptosomal-associated protein of 25 kDa, SNAP-25, is generally thought to play a role in synaptic exocytosis of neuronal messengers. Using a polyclonal antiserum against rat SNAP-25, we have shown the presence of a SNAP-25-like protein in the brain of the South-African clawed toad Xenopus laevis by Western blotting and immunocytochemistry.… (More)
As an application of the transit quality of service framework presented in the First Edition of the Transit Capacity and Quality of Service Manual (TCQSM), the Florida Department of Transportation (FDOT) required all MPOs in the state where fixed-route service operates to analyze those services based on the six measures identified in the TCQSM: service… (More)
