OBJECTIVES To assess the level of acceptance and discomfort experienced by secondary school students when undergoing an atraumatic restorative treatment (ART) restoration. SUBJECTS AND METHODS Ninety secondary school students, aged 14 and 15 years, were included in the study. The ART restorations were prepared in 90 cavities and restored using an encapsulated high-viscosity glass ionomer. The...

A comparative analysis of cavities enclosed in a tertiary structure of proteins and interfaces formed by the interaction of two protein subunits in obligate and non-obligate categories (represented by homodimeric molecules and heterocomplexes, respectively) is presented. The total volume of cavities increases with the size of the protein (or the interface), though the exact relationship may var...

We numerically and experimentally investigated the lateral coupling between photonic crystal (PhC) nanobeam (NB) cavities, pursuing high sensitivity and figure of merit (FOM) label-free biosensor. We numerically carried out 3D finite-difference time-domain (3D-FDTD) and the finite element method (FEM) simulations. We showed that when two PhC NB cavities separated by a small gap are evanescently...

OBJECTIVE To investigate the fine structural integrity of the hippocampus in patients with transient global amnesia (TGA) using high-resolution T2 reversed (T2R) MRI. METHODS The authors performed detailed structural analysis of the hippocampus in 15 patients who had recovered from an episode of TGA and 150 randomly recruited normal volunteers across the adult age spectrum using high-resoluti...

patients with pulmonary cavities are usually exposed to other pulmonary infections, especially of fungus origin, such as asnprgillosis and coccidiomycosis. they are manifested by the formation of fungus ball in these cavities, which is completely resistant to anti-fungal therapy. in these circumstance the best method of treatment is removing of the ball by surgery, in this paper a case of pulmo...

Higher order modes (HOM) can have a destructive influence on the beam emittance in the future linear colliders. Therefore it is important that the quality factor of the high impedance modes be damped under a safe level. Although attentive care was taken in designing the superconducting 9-cell cavities and the HOM couplers for the TESLA collider, a high Q and high impedance mode was discovered i...

The system of an atom couples to two distinct optical cavities with phase damping is studied by making use of a dynamical algebraic method. We adopt the concurrence to characterize the entanglement between atom and cavities or between two optical cavities in the presence of the phase damping. It is found that the phase damping can enhance the generation of entanglement between two optical cavit...

A pulmonary cavity is a gas-filled area of the lung in the center of a nodule or area of consolidation and may be clinically observed by use of plain chest radiography or computed tomography. Cavities are present in a wide variety of infectious and noninfectious processes. This review discusses the differential diagnosis of pathological processes associated with lung cavities, focusing on infec...

OBJECTIVE The aim of this study was to investigate the effects of two bonding systems, with and without antibacterial monomers, on marginal bacterial and dye leakage. MATERIALS AND METHODS Class V cavities were prepared in extracted teeth for a bacterial leakage test, and the teeth were sterilized using a steam autoclave. Four cavities were not restored for the controls, and the other teeth w...
