Disease relevance of Strigiformes

• Low glucokinase activity and high rates of gluconeogenesis contribute to hyperglycemia in barn owls (Tyto alba) after a glucose challenge [1].

High impact information on Strigiformes

• Calcium binding protein-like immunoreactivity labels the terminal field of nucleus laminaris of the barn owl [2].
• The KCNC1 (previously Kv3.1) potassium channel, a delayed rectifier with a high threshold of activation, is highly expressed in the time coding nuclei of the adult chicken and barn owl auditory brainstem [3].
• We have carried out extracellular single-unit recordings in the NA of ketamine-anesthetized barn owls [4].
• Malic enzyme (P = 0.024) was less affected by dietary glucose level in barn owls than in chickens [1].
• The activities of hepatic glucokinase, malic enzyme and phosphoenolpyruvate carboxykinase of barn owls were 16, 35, and 333% of the levels in chickens [1].

Biological context of Strigiformes

• Pharmacokinetics and anesthetic and cardiopulmonary effects of propofol in red-tailed hawks (Buteo jamaicensis) and great horned owls (Bubo virginianus) [5].

Anatomical context of Strigiformes

• 1. The influence of sound location and sound frequency on the responses of single units in the midbrain auditory area (MLD) of the owl (Tyto alba) were studied using a movable sound source under free-field conditions [6].
• Quantitative TEM analysis of the barn owl basilar papilla [7].

Associations of Strigiformes with chemical compounds

• Localization of AMPA-selective glutamate receptors in the auditory brainstem of the barn owl [8].
• Species feeding on birds (sparrow hawk) and small carnivorous mammals (barn owl) are exposed to DDT and Cd to a much higher extent than species mainly feeding on small herbivorous mammals (kestrel and weasel) [9].
• Energetic adaptation to fasting in the cold has been investigated in a nocturnal raptor, the barn owl (Tyto alba), during winter [10].
• Phytane was detected in only three samples: intestine and muscle of two buzzards and lung of one barn owl [11].
• Fluoride in the prey of barn owls (Tyto alba) [12].

Gene context of Strigiformes

• To study the evolution of owl night-activity cDNA sequences encoding the circadian core oscillator (CCO) proteins BMAL1 and CLOCK were obtained from barn owl (Tyto alba) [13].
• Each nucleus in the adult barn owl expresses characteristic levels of AMPA receptor subtypes, and all are enriched in the subunits associated with rapid desensitization (GluR2 and 4) [14].
• Development of calretinin immunoreactivity in the brainstem auditory nuclei of the barn owl (Tyto alba) [15].
• The taxonomic distribution of seven intronic indels is consistent with the Aanat derived phylogenetic trees and supports conventional family-level groupings within both Strigiformes and Caprimulgiformes [16].
• Females had higher levels than males except for C32 and C36 in barn owl, C24 in tawny owls, and all hydrocarbons (except pristane) in buzzards [11].
