Contribution of nesting experience to progesterone-induced incubation in ring doves (Streptopelia risoria).
Injections of progesterone induce incubation behavior in gonadally intact ring doves only if the doves have had previous experience with at least the nest-building phase of a breeding cycle. The present study was designed to determine whether exposure to progesterone during the nest-building phase is sufficient to account for the ability of progesterone to induce incubation at a later time or w...
متن کاملHumoral response to Mycobacterium avium subsp. avium in naturally infected ring-neck doves (Streptopelia risoria).
Creation of a reliable and easy to use serologic test would greatly improve ante mortem diagnosis of Mycobacterium avium subsp. avium and aid in the control of avian mycobacteriosis, particularly in captive birds. In order to determine whether serodiagnostics could be of value in testing ring-neck doves (Streptopelia risoria) for M. a. avium infection, Western blot analysis was used to assess t...
متن کاملEffect of tryptophan administration on circulating levels of melatonin and phagocytic activity
Our research group has previously studied the role of melatonin in the immune system of birds and mice, finding that incubation with both pharmacological and physiological doses of melatonin augmented the activity of phagocytes from these animals, and that this activity was lowered in pinealectomized animals. Since melatonin is synthesized from the amino acid tryptophan, the aim of the present ...
متن کاملSyringeal muscles fit the trill in ring doves (Streptopelia risoria L.).
In contrast to human phonation, the virtuoso vocalizations of most birds are modulated at the level of the sound generator, the syrinx. We address the hypothesis that syringeal muscles are physiologically capable of controlling the sound-generating syringeal membranes in the ring dove (Streptopelia risoria) syrinx. We establish the role of the tracheolateralis muscle and propose a new function ...
متن کاملMelatonin and Oral Cavity
While initially the oral cavity was considered to be mainly a source of various bacteria, their toxins and antigens, recent studies showed that it may also be a location of oxidative stress and periodontal inflammation. Accordingly, this paper focuses on the involvement of melatonin in oxidative stress diseases of oral cavity as well as on potential therapeutic implications of melatonin in dent...
