BACKGROUND Modern stent retriever-based embolectomy for patients with emergent large vessel occlusion improves outcomes. Techniques aimed at achieving higher rates of complete recanalization would benefit patients. OBJECTIVE To evaluate the clinical impact of an embolectomy technique focused on continuous aspiration prior to intracranial vascular embolectomy (CAPTIVE). METHODS A retrospecti...

Please cite this article in press as: Benson-A spotted hyaenas, Crocuta crocuta, Animal Be Innovative problem solving enables individuals to deal with novel social and ecological challenges. However, our understanding of the importance of innovation for animals in their natural habitat is limited because experimental investigations of innovation have historically focused on captive animals. To ...

Supplementation of wild populations with captive-bred organisms is a common practice for conservation of threatened wild populations. Yet it is largely unknown whether such programmes actually help population size recovery. While a negative genetic effect of captive breeding that decreases fitness of captive-bred organisms has been detected, there is no direct evidence for a carry-over effect o...

As firms spend a growing part of their budgets on offshore activities, they experience pressure to source increasingly more complex, less codified, and more strategic IT projects abroad. Successfully completing such projects requires close collaboration among all participants. It has been argued that firms are better off keeping such projects within their organizational boundaries by setting up...

In two experiments we exposed pairs of captive chimpanzees to food acquisition/sharing situations in which we manipulated (1) whether or not the...

Overexpression of abnormal behavior among captive primates indicates poor management practices. The type, frequency, and contributing factors behaviors vary highly across individual animals in settings. This study explored if sex, rearing history, the number visitors, type visitor-monkey interactions affected rhesus macaques (Macaca mulatta) housed at Central Zoo Kathmandu, Nepal. Behavioral ob...

Studies on the genetic diversity and relatedness of zoo populations are crucial for implementing successful breeding programmes. The European wildcat, Felis s. silvestris, is subject to intensive conservation measures, including captive breeding and reintroduction. We here present the first systematic genetic analysis of the captive population of Felis s. silvestris in comparison with a natural...

As wild populations decline, ex situ propagation provides a potential bank of genetic diversity and a hedge against extinction. These programs are unlikely to succeed if captive populations do not recover from the severe bottleneck imposed when they are founded with a limited number of individuals from remnant populations. In small captive populations allelic richness may be lost due to genetic...

Several disease syndromes in captive rhinoceroses have been linked to low vitamin status. Blood samples from captive and free-ranging black (Diceros bicornis) and white rhinoceros (Ceratotherium simum) and tissue samples of captive individuals from four rhinoceros species were analysed for vitamins A and E. Circulating vitamin A levels measured as retinol for free-ranging versus captive black a...

Lion (Panthera leo) populations have dramatically decreased worldwide with a surviving population estimated at 32,000 across the African savannah. Lions have been kept in captivity for centuries and, although they reproduce well, high rates of stillbirths as well as morbidity and mortality of neonate and young lions are reported. Many of these cases are associated with bone malformations, inclu...
