Plasma Cardiac Troponin-I Concentration in Normal Horses and in Horses with Cardiac Abnormalities.

Cardiac troponin-I (cTnI) is a highly sensitive and specific marker of myocardial injury detectable in plasma by immunoassay techniques. Inclusion criteria over a 3-year period required a diagnosis of cardiac disease accompanied by electrocardiographic (ECG) and cardiac ultrasound examinations (n = 23) in adult horses (≥2 years of age). A second group of normal adult ponies (n = 12) was studied as a reference group.

Use of integrated population models for assessing density-dependence and juvenile survival in Northern Bobwhites ().

Management of wildlife populations is most effective with a thorough understanding of the interplay among vital rates, population growth, and density-dependent feedback; however, measuring all relevant vital rates and assessing density-dependence can prove challenging. Integrated population models have been proposed as a method to address these issues, as they allow for direct modeling of density-dependent pathways and inference on parameters without direct data. We developed integrated population models from a 25-year demography dataset of Northern Bobwhites () from southern Georgia, USA, to assess the demographic drivers of population growth rates and to estimate the strength of multiple density-dependent processes simultaneously.

ERAS guidelines for esophagectomy: adherence patterns among Canadian thoracic surgeons.

Enhanced recovery after surgery (ERAS) guidelines have been incorporated across surgical specialties supported by the publication of evidence-based guidelines. The purpose of this research was to explore adherence to such guidelines among Canadian thoracic surgeons with respect to esophagectomy. A standardized questionnaire was developed comprising 43 validated ERAS recommendations.

Dating of a large tool assemblage at the Cooper's Ferry site (Idaho, USA) to ~15,785 cal yr B.P. extends the age of stemmed points in the Americas.

The timing and character of the Pleistocene peopling of the Americas are measured by the discovery of unequivocal artifacts from well-dated contexts. We report the discovery of a well-dated artifact assemblage containing 14 stemmed projectile points from the Cooper's Ferry site in western North America, dating to ~16,000 years ago. These stemmed points are several thousand years older than Clovis fluted points (~13,000 cal yr B.
