The Localization of GABA-Like Immunoreactivity in the Optic Lobe Neuropils and Optic Tracts of the Cockroach Leucophaea Maderae
… maderae was discovered to fluctuate in a circadian pattern similar to the pattern of electrical output measured from the optic nerve in L. maderae. Considering the circadian oscillator for L. maderae has been localized to the optic lobes of the brain, the discovery of GABA-like …

Comparative Study of Circadian Salivary Cortisol Levels in Colic and Noncolic Infants
… Cortisol is produced by the body according to circadian pattern as well as in response to arousing or potentially stressful events. Cortisol has been associated with infant cry behavior. This study explores the relationship between the symptoms of colic and the hormone cortisol.<br> A sample of …

Circadian Flux of Extravascular Polymorphonuclear Leukocytes in the Mouse Limbus
… the limbus and their numbers rise and fall in a circadian rhythm, peaking in the evening. Additional studies in other tissues suggest metabolic syndrome resulting from the consumption of a HFD is associated with circadian disturbances. The studies outlined in this thesis were designed to test the …

The cortisol awakening response: neuropsychological correlates and implications for function in healthy humans
… cortisol secretory activity shows a marked circadian rhythm. This rhythm is characterised by a declining pattern across the day, reaching a nadir in the late evening and early part of sleep, before gradually increasing during late sleep to reach peak levels upon subsequent morning awakening. …

Cellular Mechanisms Underlying the Action of Melatonin in the Suprachiasmatic Nucleus
… Recent attention has focused on its role in circadian physiology. The suprachiasmatic nucleus (SCN) is the circadian pacemaker in all mammals. Melatonin phase advances the circadian rhythm of the activity of the SCN neurons when administered at specific times of the day. This effect is more …

Circadian and Seasonal Variation in Pasture Nonstructural Carbohydrates and the Physiological Response of Grazing Horses
… and fructans in pasture forages, undergo circadian and seasonal variation which has direct effects on metabolism in grazing horses. Increased intake of NSC is implicated in the development of digestive and metabolic disorders, such as laminitis. A series of five studies at Virginia Tech's …

Long Term and Short Term Changes in Leptin, Insulin and Glucose in Grazing Thoroughbred Mares
The objective was to evaluate the insulin-leptin interactions in grazing mares and their impact on aspects of reproductive function using a series of four studies. Fourteen mares were first examined, 10 grazing and 4 confined to stalls in four 22-h studies in April, August, October (2005) and …
