Shipstone, Jeanine YoungAbstractThe classification of the cause of unexpected infant deaths by both pathologists and researchers may be quite inconsistent. For example, if an infant is found lying face down on soft bedding the death may still be certified as ‘sudden infant death syndrome (SIDS)’, ‘accidental suffocation’, ‘undetermined’, ‘unclassified sudden infant death (USID)’, or ‘sudden unexpected death in infancy (SUDI)’. As the ...

The occurrence of those events is in a relatively small area of urban beaches of about 30 km long, making up one of the world's highest indices of shark incidents per unit of area, totaling 64 casualties, of these 24 were fatal. To mitigate shark incidents, the knowledge on shark species involved is crucial given that each species has specific usage of the habitat and dissimilar fee...

LightowlersAbstractA three year old female water buffalo was slaughtered for human consumption on a dairy buffalo farm in eastern New South Wales, Australia. Gross examination of the offal revealed four small, superficial hydatid cysts in the liver and two larger superficial cysts in one lung. All organs were sliced and no other cysts were found. Histology and PCR confirmed the cysts to be cysts of Echinococcus granulosus senso stricto. None o...

In this study, we characterized the antiviral properties of the most promising compounds as well as investigated their propensity to induce drug resistance. Our results show that some of the selected compounds possess potent, broad-spectrum anti-influenza activity as they efficiently inhibited the replication of several strains of influenza A and B viruses, including an oseltamivir-resistant clinical isolate, with nanomolar or low-micromolar potency. The most promising compounds specifically inhibited the PA−PB1 binding in vitro and interfered with the influenza A virus polymerase activity in a cellular context, with...
