ESTHETIC REHABILITATION THROUGH CAD/CAM TECHNOLOGY-CASE REPORT (Abstract): With the progress of dental materials and techniques, CAD/CAM system curren tly allows the manufacture of high precision prosthetic restorations. Zirconia is an ideal base for porcelain because the bonding process between the zirconia and the porcelain is stronger than it is with porcelain and metal. This means that the ...

It is diicult to assess hypothetical models in poorly measured domains such as neuroendocrino-logy. Without a large library of observations to constrain inference, the execution of such incomplete models implies making assumptions. Mutually exclusive assumptions must be kept in separate worlds. We deene a general abductive multiple-worlds engine that assesses such models by (i) generating the w...

We describe the frog species Diasporus citrinobapheussp. n. from the Cordillera Central of western Panama. The new species differs from all other species in its genus in coloration, disk cover and disk pad shape, skin texture, advertisement call, and size. It is most similar to Diasporus tigrillo, from which it differs in dorsal skin texture, relative tibia length, number of vomerine teeth, ven...

In T-cells HIV-1 Nef exerts various functions and interacts with actin. In astrocytes interaction of Nef with cellular proteins is poorly understood. Therefore, human astrocytic cell clones stably transfected with nef-genes derived from HIV-1 Bru and its myristoylation-defective TH-variant were investigated by confocal laser scanning microscopy for expression of Nef and cytoskeleton proteins ac...

Abstract In marine and freshwater oxygen-deficient zones, the remineralization of sinking organic matter from photic zone is central to driving nitrogen loss. Deep blooms photosynthetic bacteria, which form suboxic/anoxic chlorophyll maximum (ACM), widespread in aquatic ecosystems, may also contribute local input matter. Yet, influence ACM on carbon cycling remains poorly understood. Using a su...
