Monitoring of microsurgically and endovascularly treated aneurysms (META): protocol for an international multicentre retrospective cohort study.

Introduction: Following endovascular treatment (EVT) or microsurgical treatment (MT) of intracranial aneurysms (IA), radiological follow-up is performed to assess for recurrence and to determine the need for re-treatment. There is a paucity of evidence describing the long-term results of EVT and MT for IA and therefore data to inform the design of follow-up protocols are lacking. The overarching aim of the META study is to determine the clinically relevant long-term outcomes of EVT and MT for IA, and use this data to create evidence based radiological and clinical follow-up protocols for these aneurysms.

Molecular species determination of cyathostomins from horses in Ireland.

Cyathostomins are globally important equine parasites, responsible for both chronic and acute pathogenic effects. The occurrence of mixed infections with numerous cyathostomin species hinders our understanding of parasite epidemiology, host-parasite dynamics, and species pathogenicity. There have been few studies of cyathostomin species occurring in horses in Ireland, where temperate climatic conditions with year-round rainfall provide suitable conditions for infection of grazing animals with bursate nematodes.

Nuclear and mitochondrial patterns of population structure in North Pacific false killer whales (Pseudorca crassidens).

False killer whales (Pseudorca crassidens) are large delphinids typically found in deep water far offshore. However, in the Hawaiian Archipelago, there are 2 resident island-associated populations of false killer whales, one in the waters around the main Hawaiian Islands (MHI) and one in the waters around the Northwestern Hawaiian Islands (NWHI). We use mitochondrial DNA (mtDNA) control region sequences and genotypes from 16 nuclear DNA (nucDNA) microsatellite loci from 206 individuals to examine levels of differentiation among the 2 island-associated populations and offshore animals from the central and eastern North Pacific.
