OBJECTIVE Mindfulness-based interventions (MBIs) have been found to be a promising approach for the treatment of recurrent courses depression. However, little is known about their neural mechanisms. This functional magnetic resonance imaging study set out investigate activation changes in corticolimbic regions during implicit emotion regulation. METHODS Depressed patients with lifetime history ...

Ultraviolet (UV)-sensitive visual pigments are widespread in the animal kingdom but many animals, for example primates, block UV light from reaching their retina by pigmented lenses. Birds have UV-sensitive (UVS) visual pigments with sensitivity maxima around 360-373 nm (UVS) or 402-426 nm (violet-sensitive, VS). We describe how these pigments are matched by the ocular media transmittance in 38...

The plotopterids (Aves, Plotopteridae) were a group of extinct wing-propelled marine birds that are known from Paleogene-aged sediments (Eocene to Miocene), mostly around the Pacific Rim (especially Japan and the northwest coast of North America). While these birds exhibit a strikingly similar wing morphology to penguins (Spheniscidae), they also share derived characters with pelecaniform birds...

The majority of bird taxa perform water bathing, but little is known about the adaptive value of this behaviour. If bathing is important for feather maintenance then birds that have not bathed should have poorer feather condition, compromised escape ability and therefore increased responsiveness to cues of predation. We conducted two experiments examining the behaviour of captive starlings resp...

Bacteria belonging to the family Chlamydiaceae cause a broad spectrum of diseases in a wide range of hosts, including humans, other mammals and birds. However, very little is known about chlamydial infections in birds in our region. In the present study, we examined 28 clinically normal birds in illegal captivity that were confiscated in the province of C6rdoba, Argentina. The objective was to ...

an experiment employing a factorial arrangement of three levels (0, 8 and 16%) of canola meal (cm), two levels (0.15 and 0.25%) of nonphytate phosphorus (npp), and two levels (0 and 450 unit/kg; as fed basis) of microbial phytase was conducted using 216 hy-line w36 laying hens from 39 to 47 weeks of age. the birds receiving cm consumed more (p < 0.05) feed than birds receiving corn-soybean meal...
