The circadian rhythm of flight activity in the mosquito Aedes aegypti (L.). The phase-setting effects of light-on and light-off.

چکیده
Various authors have reported 24 hr. cycles of activity in Aedes aegypti (L.); these reports include the field observations of Boorman (1961) on biting and McClelland (i960) on biting and flight, and the laboratory studies of Haddow & Gillett (1957) on oviposition and Gillett, Haddow & Corbet (1962) on sugar-feeding. As a result of their laboratory studies, Gillett, Haddow & Corbet (1959, 1962) and Haddow, Gillett & Corbet (1961) came to the conclusion that both oviposition and sugar-feeding are controlled by an inherited endogenous circadian rhythm, which is dependent on the change from light to dark as a time-cue. The development of an automatic method of recording flight activity in mosquitos (Jones, 1964; Jones, Hill & Hope, 1967) has made possible the present intensive study of the circadian rhythm of flight-activity in A. aegypti. This paper confirms the existence of a rhythm in constant dark and the phase-setting effect of light-off. It also draws attention to the possibility of a rhythm in constant light and to the phase-setting effect of light-on. It appears that light-off and light-on may control two different 'clocks' or possibly two 'hands' of the same 'clock'.

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...

Background: Aedes aegypti is the main vector of the yellow fever and dengue virus. This mosquito has become the major indirect cause of morbidity and mortality of the human worldwide. Dengue virus activity has been reported recently in the western areas of Saudi Arabia. There is no vaccine for dengue virus until now, and the control of the disease depends on the control of the vector. Objectiv...

Women with hereditary breast cancer predispositions should avoid using their smartphones, tablets and laptops at night
Breast cancer is the most common malignancy among women, both in the developed and developing countries. Women with mutations in the BRCA1 and BRCA2 genes have an increased risk of breast and ovarian cancers. Recent studies show that short-wavelength visible light disturb the secretion of melatonin and causes circadian rhythm disruption. We have previously studied the health effects of exposure...
