The Virtual Curation Laboratory at Virginia Commonwealth University created 3D representations of digital morphological models, termed “artifictions,” of several bone elements from two extinct animals, the passenger pigeon (Ectopistes migratorius Linnaeus Columbidae) and the harelip sucker (Moxostoma lacerum Jordan and Brayton Catostomidae). Procuring recent comparative reference skeletons these species is extremely difficult. The creation of artifictions, 3D printed replicas of skeletal remains, aims to help researchers become familiar with the bones of harelip sucker and passenger pigeon to facilitate morphological identification of remains of these species within archaeological assemblages. Here, we discuss the two species, the techniques used to create digital topological models of individual skeletal elements, and the obstacles encountered regarding 3D printed artifictions in zooarchaeology.
The Mycobacterium avium–intracellulare complex (MAC) is an uncommon cause of brain abscesses even in patients with acquired immunodeficiency syndrome (AIDS). We present a case of a multiple MAC brain abscesses, confirmed by brain biopsy and culture, in a patient with AIDS. The patient's initial symptoms were weakness, confusion and headaches. The patient was initially treated for toxoplasmosis and pyogenic bacterial brain abscesses with no resolution. Following treatment for MAC the patient's abscesses resolved.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
