EXCEPTIONALLY SIMPLE, RAPIDLY REPLACED TEETH IN SAUROPOD DINOSAURS DEMONSTRATE A NOVEL EVOLUTIONARY STRATEGY FOR HERBIVORY IN LATE JURASSIC ECOSYSTEMS

Abstract Background Dinosaurs dominated terrestrial environments for over 100 million years due in part to innovative feeding strategies.Although a range of dental adaptations was present in Late Jurassic dinosaurs, it is unclear whether dinosaur ecosystems exhibited patterns of tooth disparity and dietary correlation similar to those of modern amn

Angiostrongyliasis (Rat Lungworm disease) is an emerging parasitic disease caused by the ingestion of gastropods infected with the neurotropic nematode Angiostrongylus cantonensis.The reduction of crop infestation with infected slug carriers may vary widely by protection method.We explored the application of barriers with valve mechanisms, whereby

Human adipose-derived stem cells (hASCs) can be isolated from fat Collections tissue and have attracted interest for their potential therapeutic applications in metabolic disease.hASCs can be induced to undergo adipogenic differentiation in vitro by exposure to chemical agents or inductive growth factors.We investigated the effects and mechanism of

We describe a new complex burrow system produced by geomyids in southern Mexico.Yaviichnus inyooensis igen.isp.nov.is composed of main large chambers near the top of the paleosol, from which shafts showing different morphologies and orientations radiate, some of them ending in or connected to small deeper chambers.Gregorymys spp.is proposed as the

Participation in cancer screening and prevention (cessation of or reduction Quadra in modifiable health risk behaviors) are the most effective methods of reducing cancer morbidity and mortality.Some members of the lesbian, gay, bisexual, and transgendered (LGBT) communities have not participated in screening for a variety of reasons which have been
