Using plant circadian programs to optimize agrochemical use. [PDF]
New PhytolSummary Agrochemicals play an important role in maximizing agricultural yields. One class of agrochemicals is herbicides, which are used for weed control and to kill the top growth of certain crops before harvest. We examine the influence of plant circadian regulation on herbicide effectiveness to exemplify how knowledge of the circadian clock could be

Relojes Circadianos y Premio Nobel: hora de tomarse unos minutos para hablar de ritmos biológicos
ARS Medica, 2018 El Nobel 2017 en Fisiología o Medicina recayó en la descripción molecular de los relojes circadianos. A pocas semanas de haberse hecho el anuncio, uno de los recipientes de esta distinción, Michael Rosbash, visitó Chile.

Sono e ritmos circadianos na depressão resistente
Debates em Psiquiatria, 2014 Os distúrbios do sono e do ritmo circadiano constituem características essenciais dos quadros depressivos. As alterações do ciclo vigília-sono são frequentemente sintomas prodrômicos dos transtornos depressivos e desempenham um papel na patofisiologia ...

Relación Entre los Ritmos Circadianos y la Obesidad
Revista Científica Hallazgos21, 2021 El estudio de la cronobiología ha demostrado que la fisiología humana se adapta continuamente a los cambios cíclicos del medio ambiente, ya sean diarios o estacionales, lo cual ocurre por la presencia de un reloj biológico que regula la expresión y actividad de determinadas enzimas y hormonas implicadas en la regulación metabólica y homeostática de ...

Ritmos y relojes circadianos de las plantas
Ecosistemas, 2003 Las plantas necesitan coordinar toda su fisiología, y por ende su reproducción, con la información del ambiente que las rodea. Los ritmos biológicos permiten a las plantas anticiparse a ciertas condiciones exteriores cambiantes como luz y temperatura.

Genética molecular dos ritmos circadianos em insetos vetores
Revista Da Biologia, 2012 The majority of living organisms present an endogenous pacemaker, known as the circadian clock, responsible for driving rhythmic oscillations in their physiology and behaviour with a period of approximately 24 hours. In insects, the genetic bases of this mechanism have been elucidated in the model species Drosophila melanogaster.

Circadian rhythms of hosts and their gut microbiomes: Implications for animal physiology and ecology
Functional Ecology, Volume 37, Issue 3, Page 476-487, March 2023., 2023 Read the free Plain Language Summary for this article on the Journal blog. Abstract Daily light–dark cycles shape the circadian physiology and behaviour of nearly all organisms, with variation in circadian phenotypes having cascading effects on individual fitness, species interactions and species co‐evolution.

Alterações do Ritmo Circadiano no Atleta
Revista de Medicina Desportiva Informa, 2021 Sleep is very important for the proper functioning of the human body and consists of several stages. This text will address the concepts of biological rhythms, the circadian rhythm and body temperature, which is considered the main biological marker of the circadian rhythm.

Biotemas, 2008 Embora a maioria dos biologistas circadianos provavelmente assuma que os relógios circadianos controlem os padrões de atividade, também é sabido que estímulos ambientais podem mascarar os ritmos endógenos, quer pelo aumento ou pela supressão da ...
