Biotic resistance is the idea that native species negatively affect the invasion success
of introduced species, but whether this can occur at large spatial scales is poorly
understood. Here we re-evaluated the hypothesis that native large-bodied grouper
and other predators are controlling the abundance of exotic lionfish (Pterois volitans/miles) on...
Relative to extensive research on the freshwater stages of steelhead Oncorhynchus mykiss life history, little is known about the species’ estuarine and early marine phases despite the decline of numerous populations, including several from the Columbia River. Comparisons of the distribution, diet, and growth of juvenile steelhead collected during surveys...
Fungal hyphae are among the most highly polarized cells. Hyphal polarized growth is supported by tip-directed transport of secretory vesicles, which accumulate temporarily in a stratified manner in an apical vesicle cluster, the Spitzenkörper. The exocyst complex is required for tethering of secretory vesicles to the apical plasma membrane. We...
Rapid unloading and a peak in power output of the ankle joint have been widely
observed during push-off in human walking. Model based studies hypothesize that this
push-off to causes redirection of the body center of mass just before touch-down of the
leading leg. Other research suggests, that work done...
Objective
Our objective was to use episodic memory and executive function tests to determine whether or not Chiari Malformation Type I (CM) patients experience cognitive dysfunction.
Background
CM is a neurological syndrome in which the cerebellum descends into the cervical spine causing neural compression, severe headaches, neck pain, and number...
Phenolic acids, flavanols, flavonols and stilbenes (PAFFS) were isolated from whole grapes, juice, or pomace and purified using enzymatic hydrolysis. Only anthocyanin mono-glucosides and a few of the oligomers from
Cynthiana grape (Vitis aestivalis) were analysed. Flavonoid-anthocyanin mono-glucosides (FA) were isolated using methanol/0.1% hydrochloric acid extraction. In addition, crude extractions...
