Understanding ecological niche evolution over evolutionary timescales is crucial to elucidating the biogeographic history of organisms. Here, we used, for the first time, climate-based ecological niche models (ENMs) to test hypotheses about ecological divergence and speciation processes between sister species pairs of lemurs (genus Eulemur) in Madagascar.(More)
The optimal management of frontal sinus fractures remains controversial, and previously accepted indications for surgical intervention are being challenged. The goals of this study were to determine how frontal sinus fracture management has changed at a single institution across multiple disciplines and to evaluate the long-term outcomes of operative and(More)
OBJECTIVES To better understand the relations between occupational exposure, blood antioxidant enzyme activities, total plasma antioxidant concentration, and the severity of coal workers' pneumoconiosis (CWP). METHODS Blood samples were obtained from miners without CWP exposed to low dust concentrations for > or = 4 years at the time of the study (n =(More)
Obwohl Schmerzen der bei Weitem häufigste Grund sind, einen Arzt aufzusuchen, konnten Ärzte ihre Ausbildung abschließen, ohne sich mit Schmerz und Schmerzmanagement auseinandergesetzt zu haben. Die resultierende Unsicherheit ist vermutlich einer der Hauptgründe, weshalb eine angemessene Behandlung unterbleibt. Viele Patienten beklagen daher zu Recht eine(More)
Understanding mechanisms causing pulmonary vascular disease (PVD) frequently requires a thorough understanding of the underlying structural changes in the pulmonary circulation. Animal models have been used extensively to study different forms of PVD but conventional experimental techniques are limited in their ability to allow the study of the whole(More)
OBJECTIVE To investigate if blood Cu++/Zn++ superoxide dismutase, glutathione peroxidase, catalase, and total plasma antioxidant activities could be markers of biological activity resulting from exposure to respirable coal mine dust in active miners, and of pneumoconiosis in retired miners. METHODS Blood samples were randomly obtained from active surface(More)
This study investigated whether differences in the prevalence and severity of coal workers' pneumoconiosis (CWP) between three coal mines could be related to differences in oxidative stress exposure as evaluated in vivo through red-blood-cell antioxidant enzyme activities. Blood samples were obtained from 229 miners selected according to their occupation(More)
BACKGROUND Fifth metacarpal fractures are often treated nonoperatively with serial radiographs; however, the utility of these radiographs in altering clinical management has not been investigated. We hypothesize that follow-up plain films will not alter clinical management and are therefore unnecessary for most patients. METHODS Between 2007 and 2014,(More)
BACKGROUND We investigated if blood Cu++/Zn++ superoxide dismutase, glutathione peroxidase, and catalase activities are increased and total plasma antioxidant concentration is decreased in coke oven workers exposed to polycyclic aromatic hydrocarbons. METHODS Ninety-six coke oven workers participated in the study. Nonexposed workers (n = 105) were(More)
For this article we investigated the role of three blood antioxidant enzyme activities and total antioxidant status (TAS) as biological markers of oxidative stress in workers exposed to mercury (Hg(o)) vapors. Twenty-two female workers took part in the study. The examination included a questionnaire on age, educational level, occupational history, actual(More)
