Expression of L-type calcium channels associated with postnatal development of skeletal muscle function in mouse
Several factors have an influence on the improvement of muscle activity and motor co-ordination of mammals during post-natal development. One of them is voltage sensitive L-type calcium channel function. In st...

Fasting endurance and cold resistance without hypothermia in a small predatory bird: the metabolic strategy of Tengmalm's owl,Aegolius funereus
The energetic adaptations of non-breeding Tengmalm's owls (Aegolius funereus) to temperature and fasting were studied during the birds' autumnal irruptions in western Finland. Allometric analysis (including liter...

Hyperthermia after intrahypothalamic injections of thyrotropin releasing hormone (TRH) in the pigeon
Thermoregulatory responses to intrahypothalamic injections of thyrotropin releasing hormone (TRH) were recorded from unanesthetized pigeons exposed to 6°C, 20°C and 32°C. Our results suggest that TRH is a non-...

The influence of 6-OHDA on hypothermia produced by intrahypothalamically-injected carbachol in the pigeon
The involvement of the noradrenergic system in hypothermia induced by intrahypothalamically-injected carbachol (CCh) was studied by depleting hypothalamic noradrenaline (NA) with the catecholamine neurotoxin 6...

Opposing temperature responses to intrahypothalamic injections of 5-hydroxytryptamine in the pigeon exposed to cold
5-Hydroxytryptamine injected into posterior and anterior parts of the pigeon hypothalamus evoked a short lasting hyperthermia or hypothermia, respectively. Variable responses obtained within the same brain reg...
