Central precocious puberty is commonly treated by gonadotropin releasing hormone (GnRH) agonists. To compare modes of action and effectiveness of GnRH analogues and assess treatment combinations of agonistic (triptorelin) and antagonistic (cetrorelix

In crustaceans, melatonin has been detected in the central nervous system and some other organs. The aim of this study was to analyze the melatonin content in the visual system of Procambarus clarkii, by means of radioimmunoassay, at different day-ni

Summary We investigated a common, free living, marine, phagotrophic flagellate by light and electron microscopy. It has two heterodynamic flagella, a flexible cell shape and a pronounced apical rostrum. So far it was regarded as dinoflagellate and ca

The unicellular alga Gonyaulax polyedra reacts to short days and low temperatures by forming asexual cysts. Its photoperiodic response is elicited via the physiological mediation of melatonin. This indoleamine known as a dark signal in vertebrates is

1. In Neurospora crassa strain bd a , circadian rhythmicity was investigated in constant darkness. In the growing front of solid agar cultures, conidiation was preceded by a maximum of NAD + kinase activity. The enzyme rhythmicity was suppressed by c

Dark motility was investigated in stationary cultures of Euglena gracilis Klebs, strain Z. After several days of exposure to darkness, ultradian rhythms of different period length emerged, which could be followed for many cycles. In particular, rhyth

Dark motility was measured by means of an infrared beam in stationary, 8- to 10-months-old autotrophic cultures ofEuglena gracilis, strain Z. Controls in constant darkness exhibited circadian rhythms for several weeks. Cells were subjected to series

Although the geophysical periodicity of the earth's rotation corresponds to a biological cyclicity of ca. 24 h, cellular temporal organization comprises a multifrequency time structure, in which ultradian rhythms may be regarded as subelements of the
