Biological switches and clocks [PDF]
Journal of The Royal Society Interface, 2008 To introduce this special issue on biological switches and clocks, we review the historical development of mathematical models of bistability and oscillations in chemical reaction networks. In the 1960s and 1970s, these models were limited to well-studied biochemical examples, such as glycolytic oscillations and cyclic AMP signalling.

How to Synchronize Biological Clocks [PDF]
Journal of Computational Biology, 2009 This paper is concerned with a novel algorithm to study networks of biological clocks. A new set of conditions is established that can be used to verify whether an existing network synchronizes or to give guidelines to construct a new synthetic network of biological oscillators that synchronize.

Biological clock: Biological clocks may modulate drug addiction [PDF]
European Journal of Human Genetics, 2005 A recent study by McClung's group (2005),1 expanding on an earlier report,2 provides mechanistic insight to the timekeeper gene, Clock, which may regulate dopaminergic transmission and cocaine reward. This work provides further evidence that cocaine-induced effects have circadian influences.

Biological clocks and the digestive system [PDF]
Gastroenterology, 2000 Circadian rhythms play a major role in regulating the digestive systems of many organisms. Cell proliferation, migration, differentiation, and even structure vary as a function of time of day in many different digestive organs (i.e., stomach, gut, liver, and pancreas) and cell types, resulting in regionally specific temporal variations in protein and ...

Biological Clocks: Riding the Tides [PDF]
Current Biology, 2013 Animals with habitats in the intertidal zone often display biological rhythms that coordinate with both the tidal and the daily environmental cycles. Two recent studies show that the molecular components of the biological clocks mediating tidal rhythms are likely different from the phylogenetically conserved components that mediate circadian (daily ...

Proceedings of the National Academy of Sciences, 1999 Circadian rhythms describe biological phenomena that oscillate with an ≈24-hour cycle. These rhythms include blood pressure, body temperature, hormone levels, the number of immune cells in blood, and the sleep-wake cycle. In this paper, we will focus on common genes between species that are responsible for determining the circadian behavior ...

Genetic clock of biologic rhythms [PDF]
Journal of Cellular and Molecular Medicine, 2003 AbstractBiologic rhythms are tighly regulated in all species, in order to addapt to circadian variations of light, temperature and other biological related living conditions. The intrinsic mechanisms of rhythm regulation from every cell to a whole organism is embedded into the genetic clockwork.

A chiming biological clock? [PDF]
Current Biology, 1997 Microscopists are in the unique position of being able to encapsulate great science with a single image. The data may be complex, but the visualization can be breathtaking.Now, Olympus has joined forces with Current Biology to offer a state-of-the-art digital camera for the best photomicrograph.
