Research Article: Functional Synchronization of Biological Rhythms in a Tritrophic System

Date Published: June 10, 2010 Publisher: Public Library of Science Author(s): Sufang Zhang, Jianing Wei, Xiaojiao Guo, Tong-Xian Liu, Le Kang, Shin Yamazaki. http://doi.org/10.1371/journal.pone.0011064 Abstract: In a tritrophic system formed by a plant, an herbivore and a natural enemy, each component has its own biological rhythm. However, the rhythm correlations among the three levels and the … Continue reading

Research Article: Temperature–amplitude coupling for stable biological rhythms at different temperatures

Date Published: June 8, 2017 Publisher: Public Library of Science Author(s): Gen Kurosawa, Atsuko Fujioka, Satoshi Koinuma, Atsushi Mochizuki, Yasufumi Shigeyoshi, Attila Csikász-Nagy Abstract: Most biological processes accelerate with temperature, for example cell division. In contrast, the circadian rhythm period is robust to temperature fluctuation, termed temperature compensation. Temperature compensation is peculiar because a system-level … Continue reading

Research Article: Milk Leptin Surge and Biological Rhythms of Leptin and Other Regulatory Proteins in Breastmilk

Date Published: December 17, 2015 Publisher: Public Library of Science Author(s): Yuriy Nozhenko, Madhu Asnani-Kishnani, Ana M. Rodríguez, Andreu Palou, Eric M Mintz. http://doi.org/10.1371/journal.pone.0145376 Abstract: A significant number of chronic diseases are linked to perinatal nutrition, and prevention may be associated to naturally occurring components of breast milk. One key hormone in breast milk is … Continue reading

Research Article: Reduction Theories Elucidate the Origins of Complex Biological Rhythms Generated by Interacting Delay-Induced Oscillations

Date Published: November 7, 2011 Publisher: Public Library of Science Author(s): Ikuhiro Yamaguchi, Yutaro Ogawa, Yasuhiko Jimbo, Hiroya Nakao, Kiyoshi Kotani, Matjaž Perc. http://doi.org/10.1371/journal.pone.0026497 Abstract: Time delay is known to induce sustained oscillations in many biological systems such as electroencephalogram (EEG) activities and gene regulations. Furthermore, interactions among delay-induced oscillations can generate complex collective rhythms, which … Continue reading

Research Article: Identification of the Molecular Clockwork of the Oyster Crassostrea gigas

Date Published: January 10, 2017 Publisher: Public Library of Science Author(s): Mickael Perrigault, Damien Tran, Nicholas S Foulkes. http://doi.org/10.1371/journal.pone.0169790 Abstract: Molecular clock system constitutes the origin of biological rhythms that allow organisms to anticipate cyclic environmental changes and adapt their behavior and physiology. Components of the molecular clock are largely conserved across a broad range … Continue reading

Research Article: Diurnal Rhythms in Neurexins Transcripts and Inhibitory/Excitatory Synapse Scaffold Proteins in the Biological Clock

Date Published: May 25, 2012 Publisher: Public Library of Science Author(s): Mika Shapiro-Reznik, Anje Jilg, Hadas Lerner, David J. Earnest, Nava Zisapel, Michael Hendricks. http://doi.org/10.1371/journal.pone.0037894 Abstract: The neurexin genes (NRXN1/2/3) encode two families (α and β) of highly polymorphic presynaptic proteins that are involved in excitatory/inhibitory synaptic balance. Recent studies indicate that neuronal activation and memory … Continue reading

Research Article: Central and Peripheral Signals Set the Circadian Liver Clock

Date Published: February 30, 2007 Publisher: Public Library of Science Author(s): Liza Gross Abstract: None Partial Text: The importance of maintaining a smooth-running circadian clock becomes painfully evident whenever we suffer severe jet lag. Traveling through multiple time zones decouples our biological rhythms from the natural cycle of light and dark we’re used to. These … Continue reading

Research Article: Transient Resetting: A Novel Mechanism for Synchrony and Its Biological Examples

Date Published: August 4, 2006 Publisher: Public Library of Science Author(s): Chunguang Li, Luonan Chen, Kazuyuki Aihara, Karl J Friston Abstract: The study of synchronization in biological systems is essential for the understanding of the rhythmic phenomena of living organisms at both molecular and cellular levels. In this paper, by using simple dynamical systems theory, … Continue reading

Research Article: Defining Global Neuroendocrine Gene Expression Patterns Associated with Reproductive Seasonality in Fish

Date Published: June 5, 2009 Publisher: Public Library of Science Author(s): Dapeng Zhang, Huiling Xiong, Jan A. Mennigen, Jason T. Popesku, Vicki L. Marlatt, Christopher J. Martyniuk, Kate Crump, Andrew R. Cossins, Xuhua Xia, Vance L. Trudeau, Paul A. Bartell. http://doi.org/10.1371/journal.pone.0005816 Abstract: Many vertebrates, including the goldfish, exhibit seasonal reproductive rhythms, which are a result of … Continue reading

Research Article: Light Pollution Modifies the Expression of Daily Rhythms and Behavior Patterns in a Nocturnal Primate

Date Published: November 13, 2013 Publisher: Public Library of Science Author(s): Thomas Le Tallec, Martine Perret, Marc Théry, Paul A. Bartell. http://doi.org/10.1371/journal.pone.0079250 Abstract: Among anthropogenic pressures, light pollution altering light/dark cycles and changing the nocturnal component of the environment constitutes a threat for biodiversity. Light pollution is widely spread across the world and continuously growing. … Continue reading
