Pigment-dispersing factor signaling in the circadian system of Caenorhabditis elegans
(Wiley Blackwell Publishing, Inc, 2015-07)
The neuropeptide pigment-dispersing factor (PDF) is important for the generation and entrainment of circadian rhythms in the fruitfly Drosophila melanogaster. Recently two pdf homologs, pdf-1 and pdf-2, and a PDF receptor, ...
Retrograde bone morphogenetic protein signaling shapes a key circadian pacemaker circuit
(Society For Neuroscience, 2013-01)
The neuropeptide pigment-dispersing factor (PDF) synchronizes molecular oscillations within circadian pacemakers in the Drosophila brain. It is expressed in the small ventral lateral neurons (sLNvs) and large ventral lateral ...
Chemical and structural composition of black pigmented supragingival biofilm of bovines with periodontitisComposição química e estrutural do biofilme supragengival pigmentado de bovinos com periodontite
(2019-12-01)
Bovine periodontitis is a multifactorial disease primarily associated with a potentially pathogenic microbiota housed in the oral biofilm of animals. Biofilms are organized structures, in which the constituents coexist in ...
Impaired clock output by altered connectivity in the circadian network
(National Academy of Sciences, 2007-03)
Substantial progress has been made in elucidating the molecular processes that impart a temporal control to physiology and behavior in most eukaryotes. In Drosophila, dorsal and ventral neuronal networks act in concert to ...
Circadian Period Integrates Network Information Through Activation of the BMP Signaling Pathway
(Public Library of Science, 2013-12-10)
Living organisms use biological clocks to maintain their internal temporal order and anticipate daily environmental changes. In Drosophila, circadian regulation of locomotor behavior is controlled by ∼150 neurons; among ...
The Drosophila Neuropeptides PDF and sNPF Have Opposing Electrophysiological and Molecular Effects on Central Neurons
(American Physiological Society, 2014-03)
Neuropeptides have widespread effects on behavior, but how these molecules alter the activity of their target cells is poorly understood. We employed a new model system in Drosophila melanogaster to assess the electrophysiological ...
High-frequency neuronal bursting is essential for circadian and sleep behaviors in drosophila
(Society for Neuroscience, 2021-01)
Circadian rhythms have been extensively studied in Drosophila; however, still little is known about how the electrical properties of clock neurons are specified. We have performed a behavioral genetic screen through the ...
Rol del neuropéptido PDF en la adquisición y el mantenimiento de la estructura del circuito PDFRole of the PDF neuropeptide in the acquisition and maintenance of the PDF circuit structure

Effect of extrinsic pigmentation and surface treatments on biaxial flexure strength after cyclic loading of a translucent ZrO2 ceramic
(2019-11-01)
Objective: To evaluate the influence of extrinsic pigmentation on the biaxial flexural strength and surface topographic of translucent Y-TZP (InCoris TZI – Sirona – USA) subjected to several surface treatments. Methods: ...
