The geographic isolation and the prolonged absence of sunlight during winter make Antarctica an interesting environment for studying circadian rhythms. This study explored the effects of wintering on sleep, hormonal, and electrolyte rhythms in four human subjects living in a small Antarctic base. Up to the last sunset sleep, 6-sulfatoxymelatonin, cortisol, sodium, and potassium rhythms were synchronized within clock time. During the 126 days of winter, when there was no sunlight, the circadian rhythms of all measures free ran in each individual. For example, the free-running periods for the co

The photoperiod-induced clock-shifting in the free running time of the circadian protein and amino acid rhythms was studied in the larval fat body of Bombyx mori. The analysis of peaks and troughs of phase response curves of the rhythm revealed that the fourth and fifth instar larvae grown under normal 12 h light and 12 h dark cycle (LD) showed 7 protein synthetic cycles, while those reared under continuous light (LL) recorded 9.5 cycles in fourth instar and 8 in fifth instar. Under continuous dark (DD), the protein rhythm maintained 8 cycles in fourth instar and 7.5 cycles in fifth instar. Cl

Without a zeitgeber the circadian rhythms of five physiological functions free-ran with a period length greater than 24 h. Restricted feeding time (RF) masked the free-running rhythms. In addition to masking, entrainment with RF occurred. This process was most evident in locomotor activity and visits to the food box. RF thus had zeitgeber properties in these rabbits. However, in most rabbits the RF zeitgeber was not strong enough to entrain the circadian rhythm completely. A small component free-ran during RF. Following return to continuous food access the whole circadian rhythm resumed to fre

Many species show rhythmicity in activity, from the timing of flowering in plants to that of foraging behavior in animals. The free-running periods and amplitude (sometimes called strength or power) of circadian rhythms are often used as indicators of biological clocks. Many reports have shown that these traits are highly geographically variable, and interestingly, they often show latitudinal or longitudinal clines. In many cases, the higher the latitude is, the longer the free-running circadian period (i.e., period of rhythm) in insects and plants. However, reports of positive correlations be

Abstract Clock is a semidominant X-linked mutation that results in shortening the period of Drosophila melanogaster's free-running locomotor activity rhythm from ca. 24.0 to ca. 22.5 hr. This mutation similarly shortened the phase response curve, determined by resetting activity rhythms with light pulses. Eclosion peaks for Clk cultures were separated by only 22.5 hr instead of the normal 24 hr. Clk was mapped close to, but separable from, another rhythm mutation--period01--by recombination. The estimated distance between these two mutations was short enough to suggest that Clk could be a per

The causes of age-related disruptions in the timing of human sleep and wakefulness are not known but may include changes in both the homeostatic and circadian regulation of sleep. In Syrian hamsters the free running period of the circadian activity/rest rhythm has been reported to shorten with age. Although this has been observed under a variety of experimental conditions, the changes have been small and their consistency uncertain. In the present study, the wheel running activity/rest rhythm was continuously measured in male Syrian hamsters ( Mesocricetus auratus) in dim constant light (<1

Shifting the onset of light, acutely or chronically, can profoundly affect responses to infection, tumor progression, development of metabolic disease, and mortality in mammals. To date, the majority of phase-shifting studies have focused on acute exposure to a shift in the timing of the light cycle, whereas the consequences of chronic phase shifts alone on molecular rhythms in peripheral tissues such as skeletal muscle have not been studied. In this study, we tested the effect of chronic phase advance on the molecular clock mechanism in two phenotypically different skeletal muscles. The phase

Experiments were conducted to determine the anatomic and physiological basis of the dual-oscillator circadian system of female Japanese quail. After blocking of ocular light perception by eye-patching, the circadian body temperature rhythm dissociates into two circadian components in continuous lighting (LL). One component free runs with a period significantly shorter than 24 h [mean period (tau) = 22.7 h] and is driven by an ocular pacemaker, whereas the other component free runs with a period significantly longer than 24 h (tau = 26.3 h). The long free-running rhythm is driven by the same ci

An organism’s circadian clock exists as a self-regulating oscillator that can synchronize with its surroundings. This manifests as physiological and behavioral output which can anticipate changes in environment. These rhythms may even persist internally and are known to oscillate at a period (tau) of around 24 hours even in the absence of external cues. In the laboratory, such rhythmic output is known as a free-running period (FRP). Given that circadian rhythms are distributed in a number of taxa as well as their tendency to oscillate along with the solar day, it has been suggested that they r

A characteristic feature of species of Trichoderma is the production of concentric rings of conidia in response to alternating light-dark conditions. In response to a single burst of light, a single ring of conidia forms at what was the colony perimeter. On the basis of these observations, competency to photoconidiate has been proposed to be due to the age and metabolic rate of the hyphal cell. In this study, conidiation was investigated in five biocontrol isolates (T. hamatum, T. atroviride, T. asperellum, T. virens and T. harzianum) using both a morphological and molecular approach.

Temporal organization of nervous system function includes daily rhythms driven by a molecular-genetic hypothalamic “clock” with an intrinsic period length of approximately (circa) one day (diem). The resulting circadian rhythm influences all aspects of brain function and internally synchronizes the circadian oscillations inherent in all other body tissues. Idiosyncratic circadian characteristics interact with perceived environmental stimuli to determine each individual’s entrainment pattern of external synchronization with the day-night cycle. Idiosyncratic entrainment patterns that may come t

Streszczenie:

The pineal gland transduces light–dark cycles for the timing of body rhythms by secretion of melatonin, an endogenous indoleamine derived from tryptophan, the concentrations of which in plasma and cerebrospinal fluid are up to 100 times higher at night than in the daytime. This exerts its effects through transmembrane, G-protein coupled receptors (MT1 and MT2), and nuclear receptors primarily in the suprachiasmatic nucleus, pars tuberalis of the pituitary gland and hypothalamus. The natural period of the human circadian system is on average 24.1 to 24.3 h, and the principal resetting agent is light. Exogenous melatonin can shift the timing of the internal clock to earlier and later times, and synchronize a free-running clock that is not properly entrained to the 24-h day, hence it may have a therapeutic role for disorders of sleep rhythm including jet lag, in shift workers, and in blind people.

The second chapter, Exercise, considers the rhythm of our bodies in motion and the complicated relationships between exercise and illness, as both a necessity and a joy. Like eating, the significance of exercise is redefined by illness, and the body is maintained, challenged, and re-known through it. Exercise regimes can provide control, treatment and an alternative form of medication so that through physical activity bodies feel strong, independent, and free in spite of illness. But ill bodies are prone to overexertion, and exercise can reinforce their dependence and vulnerability as well as their strength. For Anna, who has depression, exercise has become a form of self-medication. Running and cycling regularly make her feel less depressed, so she tries to be physically active at least four times a week. Disruption to this routine can cause her mood to plummet quickly, showing the dependence that she has on her body.

The paper introduces a relay feedback oscillator for modeling circadian rhythms in cyanobacteria. The relay feedback oscillator is equipped with low pass filter F(jω), hysteresis-type relay and negative feedback. This negative feedback represents an autoregulatory mechanism of the circadian clock and the notion of this autoregulatory mechanism is based on the well-known Goodwin biochemical oscillator [1]. The relay is responsible for the mediation of both the activation and degradation of oscillator state variables (protein concentrations) and in this way the pacemaker is constituted. Later on
