Abstract

A new method was proposed to analyze a basic rest-activity cycle (BRAC), termed BRAC-A. This method calculates a significant cycle length by chi-squared method and the starting points of a resting phase and an active one by analysis of the array consisting of the segmented time series in the same length. Using 20 3-day computer-simulated time series of standard deviation in fetal heart rate fluctuation with known periodicity of the BRAC, we demonstrated that the BRAC-A was a useful tool to reveal the characteristics of the BRAC.

Systemic hemodynamic changes raising brain temperature in REM sleep.

The present research studied the mechanisms underlying the increase in brain temperature during REM sleep in the unrestrained rabbit carrying chronically implanted electrodes, thermistors and common carotid artery occluders. During the ultradian wake-sleep cycle at constant ambient temperature (25+/-2 degrees C), we recorded: (i) the ear pinna temperature as an indirect indicator of blood flow affecting heat loss from the systemic heat exchangers of the head, (ii) the temperature of the pons and hypothalamus as indirect indicators of the temperature of vertebral artery blood (systemic cooling only) and carotid artery blood (both systemic and selective cooling), respectively, and (iii) the changes induced in these temperatures by short-lasting bilateral common carotid artery occlusion. The results show that during REM sleep both systemic and selective brain cooling are depressed by a spontaneous decrease in the common carotid artery blood flow and the associated autoregulatory increase in the vertebral artery share of the cerebral blood supply.

Respiratory oscillations in yeast: clock-driven mitochondrial cycles of energization.

Respiratory oscillations in continuous yeast cultures can be accounted for by cyclic energization of mitochondria, dictated by the demands of a temperature-compensated ultradian clock with a period of 50 min. Inner mitochondrial membranes show both ultrastructural modifications and electrochemical potential changes. Electron transport components (NADH and cytochromes c and c oxidase) show redox state changes as the organisms cycle between their energized and de-energized phases. These regular cycles are transiently perturbed by uncouplers of energy conservation, with amplitudes more affected than period; that the characteristic period is restored after only one prolonged cycle, indicates that mitochondrial energy generation is not part of the clock mechanism itself, but is responding to energetic requirement.

Temporal coherence in ultradian sleep EEG rhythms in a never-depressed, high-risk cohort of female adolescents.

BACKGROUND: Previous work has indicated that low temporal coherence of ultradian sleep electroencephalographic rhythms is characteristic of depressed patients and of depressed women, in particular. It may also be evident in one quarter of those at high risk, based on a family history of depression. METHODS: The present study evaluated temporal coherence of sleep electroencephalographic rhythms in 41 adolescent girls with a maternal history of depression (high risk) and 40 healthy controls (low risk). The entire sample was followed clinically every 6 months for 2 years. RESULTS: Temporal coherence was significantly lower among the high-risk girls than in controls. Regression analyses predicted group from coherence values and correctly classified 70% of the high-risk group with a false-positive rate of 5% among controls. Moreover, 54% of the high-risk girls were identified with extreme low coherence. On clinical follow up, 14 girls showed depressive symptoms, 9 in the high-risk group (22.5%) and 5 controls (12.2%). Six met DSM-IV criteria for first-episode major depressive disorder, five high-risk and one control. Most importantly, 41% of those identified as having the most abnormal coherence values either showed symptoms of depression or met diagnostic criteria upon follow up. CONCLUSIONS: Low temporal coherence is evident in adolescent girls at high risk for depression. The more abnormal the coherence, the greater the risk of a first episode of major depressive disorder within 2 years of sleep study, approximately 10 times greater than in controls.
