REM sleep-dependent short-term and long-term hourglass processes in the ultradian organization and recovery of REM sleep in the rat
(Oxford University Press, 2020)
Study Objectives: To evaluate the contribution of long-term and short-term REM sleep homeostatic processes to REM sleep recovery and the ultradian organization of the sleep wake cycle.
Methods: Fifteen rats were sleep ...
The vertebral column of the hourglass dolphin (Lagenorhynchus cruciger, Quoy and Gaimard, 1824), with notes on its functional properties in relation to its habitat
(European Association for Aquatic Mammals, 2016-04)
Fast-swimming dolphins have a relatively stable morphological configuration, explained partially by their vertebral morphology. The hourglass dolphin (Lagenorhynchus cruciger), an oceanic species, is one of the least known ...
Can habitat characteristics shape vertebral morphology in dolphins? An example of two phylogenetically related species from southern South America
(Wiley Blackwell Publishing, Inc, 2017-07)
Fast swimming pelagic cetacean species have osteological characteristics that promote a more stable spine in comparison to that of coastal species. The Peale?s dolphin (Lagenorhynchus australis) and the hourglass dolphin ...

(Escuela Superior Politécnica de Chimborazo, 2016-11-23)
The present Word of qualification shall submit the design and front structural simulation of the Alpha bus 700 in the Company Metal Pillapa for interprovincial transport non-linear field using ANSYS. A quantitative methodology ...
Positive selection in Nucleoporins challenges constraints on early expressed genes in Drosophila development
(Oxford University Press, 2013-10)
Developmental conservation among related species is a common generalization known as von Baer’s third law and implies that early stages of development are the most refractory to change. The “hourglass model” is an alternative ...
Analysis design and testing of an hourglass-shaped copper energy dissipation device
(2014)
The behavior of a bi-directional energy dissipation device made of copper was investigated. The development considered four phases; (1) characterization and numerical modeling of the cyclic plastic behavior of Electrolytic ...
Privación selectiva de sueño rem en ratas : recuperación espontánea versus enmascaramiento: un estudio de homeostasis de sueño rem
(Universidad de Chile, 2017)
La homeostasis de sueño REM refiere el proceso mediante el cual la cantidad de tiempo en este estado se mantiene dentro de límites mínimos aceptables; sin embargo existen reportes contradictorios respecto a si el sueño REM ...
Feed processing effects on digestibility, palatability, excreta fermentation products and blood parameters in blue-fronted amazon parrots (Amazona aestiva) †
(2019-01-01)
Captive parrots show a high incidence of obesity and other metabolic disorders due to the consumption of unbalanced diets. Therefore, this study evaluated the digestibility and metabolic effects of transitioning blue-fronted ...
Vertebral Morphology in Partially Sympatric Dolphins: A 3D Approach
(Frontiers Media S.A., 2020-11)
In cetaceans, increased body flexibility is associated with increased maneuverability, this affects the animal’s swimming speed and foraging behavior. A more stable body form is associated with fast swimming and wide turns. ...
From Devo to Evo: patterning, fusion and evolution of the zebrafish terminal vertebra
(BMC, 2020)
Background With more than 30,000 species, teleosts comprise about half of today's living vertebrates, enriched with a wide set of adaptations to all aquatic systems. Their evolution was marked by modifications of their ...
