Moose and snowshoe hare competition and a mechanistic explanation from foraging theory
(Springer-Verlag, 1984-02)
Moose ( Alces alces ) and snowshoe hare ( Lepus americanus ) appear to compete with each other. This was determined using the “natural experiments” of populations found in sympatry and allopatry on islands at Isle Royale ...
Bright artificial light produces subsensitivity to nicotine
(Elsevier, 1988)
Bright artificial light is a treatment for seasonal depression. Eleven (11) rats were exposed to bright artificial light (11,500 lux) for two consecutive weeks. The thermic response to nicotine was measured prior to light ...
Automaton models of reproduction by self-inspection
(Elsevier, 1977-06-07)
There is a strategy by which an automaton can examine itself to obtain a complete description of its own constituent structure. This strategy is here employed to show that machine self-reproduction by means of self-inspection ...
Identification of a new site of conformational heterogeneity in unfolded ribonuclease A
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1990-10)
The results presented here indicate that there are two slowly exchanging conformational isomers in unfolded bovine pancreatic ribonuclease A (RNase A) in the vicinity of Lys-41. The conformational heterogeneity is not ...
Heat lability of NADPH at physiologic p H
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1972-12)
Disturbance of feeding behavior in the spiny lobster, Panulirus argus , following bilateral ablation of the Medulla terminalis
(Springer-Verlag, 1970-06)
1. Bilateral eyestalk ablation of spiny lobsters results in:
Distinctive spatiotemporal expression patterns for neurotrophins develop in gustatory papillae and lingual tissues in embryonic tongue organ cultures
(Springer-Verlag, 2001-01)
Brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) mRNAs are expressed in the developing rat tongue and taste organs in specific spatiotemporal patterns. BDNF mRNA is present in the early lingual gustatory ...
Affinity isolation of RNA polymerase II on amanitin-Sepharose
(Elsevier, 1984-02-29)
We report here the first case of an affinity isolation of eukaryotic RNA polymerase II. The procedure employs an affinity matrix composed of [alpha]-amanitin coupled to Sepharose 4B via a ten atom spacer. RNA polymerase ...
Understanding Human Lung Development through In Vitro Model Systems
(Wiley Periodicals, Inc., 2020-06)
An abundance of information about lung development in animal models exists; however, comparatively little is known about lung development in humans. Recent advances using primary human lung tissue combined with the use of ...
The Anti‐G0 Manifesto: Should a problematic construct (G0) with no biological reality be removed from the cell cycle? Yes!
(Wiley Periodicals, Inc., 2021-03)
It is widely accepted that there exists a “resting” or “quiescent” state where a growing cell leaves the cell cycle to enter what is often called the “G0‐phase.” I propose that there is no biological reality to the “G0‐phase.” ...
