Effect of D2O on the circadian rhythm of petal movement of Kalanchoe.
نویسندگان
چکیده
D20 lengthens the free running period of the circadian petal movement of isolated Kalanchoe flowers by 1.6% per 10% heavy water. This corresponds to findings reported in the literature for other organisms. 100% D20 administered in the form of 4 hour pulses at various phases of the circadian cycle lead to phase responses zero to maximally 1.5 hour delays. No advancing phase shifts occur. Possible ways in which lengthening of the period occurs are discussed.

An endogenous rhythm in the rate of carbon dioxide output of Bryophyllum. IV. Effect of intensity of illumination on entrainment of the rhythm by cycles of light & darkness.
Excised leaves of the succulent plant Bryophyllum fedtschenkoi show an endogenous circadian rhythm in their rate of carbon dioxide emission (17,18). The rhythm occurs when leaves kept at a constant temperature and in an air stream initially free from carbon dioxide are transferred from light to prolonged darkness. The entrainment of the basic oscillating system in Bryophyllum leaf cells by vari...
متن کاملEffects of lithium on stomatal regulation.
Recent findings indicate that lithium belongs to the group of rather exclusive agents which affect the period of circadian clocks: The period of the cir cadian petal movements of Kalanchoe is increased by about 2 hours in 5 m M LiCl 2. In the present paper we will report an action of lithium on a much more rapid oscillation, which under certain circum stances occurs in stomatal regulation. Th...

Abstract Vasoactive Intestinal Polypeptide (VIP), has been found in different neurotransmitter systems and exists in various nerve tracts in the brain. Potential role of this peptide in physiological processes such as regulation of sleep and wakefulness, and biological rhythms has been confirmed in several reports. In the present research effects of intracerebroventricular (ICV) injection of a...

Introduction: Chronic hyperglycemia is associated with an increase in cellular damage due to oxidative stress in pancreatic tissue. The effect of exercise in different phases of the circadian cycle on protecting pancreatic tissue from oxidative stress in diabetic patients is unknown. The aim of this study was to investigate the effect of eight weeks of endurance training in light and dark phase...

Circadian rhythms are driven by endogenous clock gene and affects in several gastric parameters causing ulcerogenesis. The study was aimed to evaluate the time dependent antiulcer activity of hydroxyzine in cold-stress-induced ulcer model. The ulcer protection effect of hydroxyzine was studied at various time intervals (9 am, 1 pm, 5 pm, 91 pm, 1 am and 5 am) in cold stress ulcer model using wi...
