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 ...
Developmental and light-entrained expression of melatonin and its relationship to the circadian clock in the sea anemone Nematostella vectensis
(2014-08-14)
Abstract
Background
The primary hormone of the vertebrate pineal gland, melatonin, has been identified broadly throughout the eukaryotes. While the role for melatonin in cyclic behavior via ...
Daily rhythms of catalase and glutathione peroxidase expression and activity are endogenously driven in the hippocampus and are modified by a vitamin A-free diet
(Maney Publishing, 2013-03)
Objectives: Alterations in enzymatic antioxidant defense systems lead to a deficit of cognitive functions and altered hippocampal synaptic plasticity. The objectives of this study were to investigate endogenous rhythms of ...
Falls risk, circadian rhythms and melatonin : current perspectives
(Dove Medical Press, 2020)
Abstract: Aging is associated with weakening of the circadian system. The circadian
amplitude of most physiological variables is reduced, while the circadian phase becomes
more labile and tends to occur earlier with ...
Circadian Phase Prediction From Non-Intrusive and Ambulatory Physiological Data
(2021)
Chronotherapy aims to treat patients according to their endogenous biological rhythms and requires, therefore, knowing their circadian phase. Circadian phase is partially determined by genetics and, under natural conditions, ...
Circadian expression of clock genes in two mosquito disease vectors: cry2 is different
(SAGE Publications, 2020)
Integrating circadian and gibberellin signaling in Arabidopsis : Possible links between the circadian clock and the AtGID1 transcription
(Taylor & Francis, 2011-09)
The circadian clock acts as central coordinator of plant activity, and it regulates key traits for plant fitness such as flowering time, gas exchange, growth and stress responses. In the May issue of the Proceedings of the ...
Saguis (Callithrix jacchus) sob ciclo claro-escuro de 21 h: um modelo de dessincronização forçada em primata diurno
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em PsicobiologiaEstudos de Comportamento; Psicologia Fisiológica, 2012-07-05)
The circadian system consists of multiple oscillators organized hierarchically, with the
suprachiasmatic nucleus (SCN) as the master oscillator to mammalians. There are lots of
evidences that each SCN cell is an oscillator ...
Gender-related differences in circadian rhythm of rat plasma acetyl- and butyrylcholinesterase: Effects of sex hormone withdrawal
(Elsevier B.V., 2010-06-07)
The role of acetylcholinesterase (AChE) in the termination of the cholinergic response through acetylcholine (ACh) hydrolysis and the involvement of plasma butyrylcholinesterase (BuChE), mainly of hepatic origin, in the ...
