Circadian Rhythms: How Does a Reindeer Tell Time?

came from genetic studies in humans. Complete CSNB (type 1 CSNB) had previously been linked to mutations in the mGluR6 and nyctalopin (whose function is still unknown) genes [11]. Three independent studies now show that mutations in TRPM1 are also a common cause of type 1 CSNB [6–8]. These observations confirm a crucial role for TRPM1 in the ON bipolar cell transduction cascade and provide new ...

Concepts in human biological rhythms

Biological rhythms and their temporal organization are adaptive phenomena to periodic changes in environmental factors linked to the earth's rotation on its axis and around the sun. Experimental data from the plant and animal kingdoms have led to many models and concepts related to biological clocks that help describe and understand the mechanisms of these changes. Many of the prevailing concep...

Biological Rhythms in the Skin

Circadian rhythms, ≈24 h oscillations in behavior and physiology, are reflected in all cells of the body and function to optimize cellular functions and meet environmental challenges associated with the solar day. This multi-oscillatory network is entrained by the master pacemaker located in the suprachiasmatic nucleus (SCN) of the hypothalamus, which directs an organism's rhythmic expression o...

Biological Rhythms and Preeclampsia

The impact of impaired circadian rhythm on health has been widely studied in shift workers and trans-meridian travelers. A part from its correlation with sleep and mood disorders, biological rhythm impairment is a recognized risk factor for cardiovascular diseases and breast cancer. Preeclampsia is a major public health issue, associated with a significant maternal and fetal morbidity and morta...
