PURPOSE The purpose of this study was to evaluate, in situ, the initial adhesion of microorganisms to as well as the surface roughness and chemical composition of ProBase Hot (Ivoclar Vivadent), a hard acrylic resin, and Vertex Soft (Vertex-Dental), an acrylic-based soft liner, used in removable dental prostheses. MATERIALS AND METHODS Equal sized disks of ProBase Hot and Vertex Soft were pre...

An elusive chemical contribution to SERS is investigated by estimating the chemical coupling strengths through a dynamic relative peak analysis during solvent evaporation from a diluted chemical sample that is drop-deposited on a soft SERS substrate.

mesoblastic nephroma is a rare entity in adulthood. we report a case of mesoblastic nephroma in a 35-year-old woman who presented with left flank pain. computed tomography images favored a soft tissue mass in the upper pole of the left kidney. the lesion was excised and sent for pathological analysis. pathological and immunohisto- chemical studies favored a diagnosis of mesoblastic nephroma.

We investigate the Belousov-Zhabotinzky (BZ) reaction as a substrate for computation. Expanding on previous research we present a new technique that utilizes two modes of the BZ reaction, excitation and oscillation, and selective diffusive coupling. We show in simulation that this technique can be used to invert input signals, providing the logical operator, NOT. Our system can readily compute ...

Chemical oxidation of poly(enetetramine)s was demonstrated as a new synthetic route to prepare conjugated polyelectrolytes.
