Adhesion of an endodontic sealer to dentin and gutta-percha: shear and push-out bond strength measurements and SEM analysis [PDF]

open access: yes, 2009
The use of an adequate method for evaluation of the adhesion of root canal filling materials provides more reliable results to allow comparison of the materials and substantiate their clinical choice. The aims of this study were to compare the shear bond

Gleaning the Rocky Shore? 2500 Years of Coastal Resource Use at Red Bluff 1, GunaiKurnai Country, SE Australia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Shell middens in Gippsland along the eastern half of Victoria's coastline have usually been characterised as small, short‐duration camp sites with relatively low shell densities and low taxonomic diversity. Here we present new excavation results from a dense, high‐diversity site at Red Bluff near the eastern end of GunaiKurnai Country, a ...

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

A comprehensive embryonic staging series of the turtle Trachemys scripta

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

Streptozotocin induced hyperglycemia in the axolotl

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Diabetes is a group of diseases characterized by loss of β cell mass and/or function, resulting in hyperglycemia. With no established curative treatment, this has initiated research in β cell regeneration. Current animal models have either limited regenerative capacity (mice) or small size and evolutionary distance from humans ...
