DAILY VARIATION IN PLASMA-CONCENTRATION OF FENCAMFAMINE AND STRIATAL DOPAMINE-RECEPTORS IN RATS
(Associação Brasileira de Divulgação Científica (ABRADIC), 1994-03-01)
Fencamfamine (FCF) is a psychostimulant drug classified as an indirect dopamine agonist. In the present study we evaluated the daily variation in plasma FCF concentration and in striatal dopamine receptors. Adult male ...

What season suits you best? Seasonal light changes and cyanobacterial competition
(Instituto de Física de Líquidos y Sistemas Biológicos, 2015-03-29)
Nearly all living organisms, including some bacterial species, exhibit biological processes with a period of about 24 h called circadian (from the Latin circa, about and dies, day) rhythms. These rhythms allow living ...
Sequential feeding with diets varying in amino acid content for growing-finishing pigs
(Univ Sao Paolo, 2021-01-01)
This study aimed to evaluate the effects of daily phase feeding (DP) and sequential feeding (SEQ) on the feeding behavior, performance, and body composition of growing-finishing pigs. Sixty barrows at 29.7 +/- 2.8 kg body ...
Daily variations in human plasma fluoride concentrations
(ELSEVIER SCIENCE SA, 2008)
This study investigated the variations in human plasma fluoride concentrations ([F]) and sought to determine the causes. Five subjects (27-33 years old) received a low-F diet during the 5 days of the study. Plasma samples ...
Alterations of locomotor activity rhythm and sleep parameters in patients with advanced glaucoma
(Taylor & Francis, 2012-08)
The aim of this study was to evaluate the effect of advanced glaucoma on locomotor activity rhythms and related sleep parameters. Nine normal subjects and nine age-matched patients with bilateral advanced primary open-angle ...
Entrainment of circadian rhythms to irregular light/dark cycles: A subterranean perspective
(Nature Publishing Group, 2016-10)
Synchronization of biological rhythms to the 24-hour day/night has long been studied with model organisms, under artificial light/dark cycles in the laboratory. The commonly used rectangular light/dark cycles, comprising ...
Daily changes in the electric behavior of weakly electric fish naturally persist in constant darkness and are socially synchronized
(Company of Biologists Ltd, 2018)
Daily rhythms allow anticipation of changes and allocation of energy to better cope with predictable events. Rhythms in behavior result from a complex combination of physiological processes timed by the nervous system and ...
