Circadian rhythms and migraine
Cleveland Clinic Journal of Medicine, 1992 To determine whether migraine exhibits a circadian rhythm or occurs randomly throughout the day, we analyzed the time of migraine onset in 15 migraine suffers (migraineurs) over 20 weeks. The patients suffered 211 migraine attacks over 20 weeks (range 3 to 30, median 13).

What is the Effect of Social Rhythm Disrupting Events on Mood in Individuals with Bipolar Disorder? [PDF]
, 2013 The social zeitgeber hypothesis suggests that life events have the capacity to lead to the onset of affective episodes in those vulnerable to bipolar disorder via biological and social rhythm disruption. However, few studies have systematically evaluated

Structural investigation of the Arabidopsis thaliana circadian clock [PDF]
Plants, like most organisms, have developed elaborate mechanisms for anticipating periodic environmental changes. The circadian clock allows an organism to adapt its metabolic, developmental and physiological processes to coincide with favourable ...

Effects of sex, mating status, and genetic background on circadian behavior in Drosophila
Frontiers in NeuroscienceCircadian rhythms play a crucial role in regulating behavior, physiology, and health. Sexual dimorphism, a widespread phenomenon across species, influences circadian behaviors.

The Role of TASK-3 Two-Pore Domain Potassium Channels in the Entrainment of Mammalian Circadian Rhythms [PDF]
, 2014 In mammals light is the principal timing cue for alignment of physiology to the external environment. Illumination from the unrelenting 24-hour day-night cycle enters the biological system and is communicated to the master pacemaker, the suprachiasmatic

Investigating the Relationship Between Circadian Rhythm and Learning-Memory
Türk Uyku Tıbbı DergisiThe circadian rhythm creates many metabolic changes in our body by influencing the activities of suprachiasmatic nucleus and other centers in the cerebrum according to the light-dark conditions within a 24-hour period.

, 2013 We discuss a class of models arising in the study of circadian rhythm and the properties of the matrix equations providing the bifurca- tion points for a wide parameter class. In particular, we prove that the five dimensional system studied in the cited work of Gonze, Halloy, and Goldbeter can have only a simple Hopf bifurcation.

Circadian Rhythm Of Wrist Temperature And Night Shift-work
, 2015 The stability of the circadian rhythms, especially regarding their amplitude and phase relationship, is a major factor for health. Shift-work and working night shifts are known to be associated with a variety of health problems caused, at least partially,
