The order Rodentia comprises more than 2000 species divided into 3 groups based on anatomic and functional differences of the masseter muscle. Myomorph and sciuromorph species have elodont incisors and anelodont cheek teeth, unlike hystrichomorph species which have full anelodont dentition. Diseases
It has long been recognized that atomic emission of radiation is not an immutable property of an atom, but is instead dependent on the electromagnetic environment1 and, in the case of ensembles, also on the collective interactions between the atoms2-6. In an open radiative
Chiral molecules that do not superimpose on their mirror images are the foundation of all life forms on earth. Chiral molecules exhibit chiroptical responses, i.e., they have different electromagnetic responses to light of different circular polarizations. However, chiroptical responses in natural
A {Ni(9)(N(3))(9)} metallamacrocycle is able to coordinate azide and halide anions in trigonal prismatic cavities by means of H-bond interactions. It provides an unprecedented example of a self-assembled cryptand-like cavity.
Pleural and peritoneal fluids from humans with pathological diseases were examined for the presence of carcinoembryonic antigen-like substances (CEA-LS). Among eight samples tested by a solid phase radioimmunoassay, two pleural fluids and one peritoneal fluid showed significantly elevated
A 45-year-old man was admitted to the hospital because of an increase in the size of an abnormal shadow on chest X-ray films over the preceding 5 years. A chest X-ray film on admission revealed a round air space in a mass-like shadow in the right upper lung field. Results of physical examination,
OBJECTIVE
To assess whether pastes containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and calcium sodium phosphosilicate (CSP) control artificial caries lesion progression.
METHODS
Enamel slabs of bovine teeth were embedded in polyester resin and had their enamel surfaces
Ion channels contain narrow columns of water molecules. It is of interest to compare the structure and dynamics of such intrapore water with those of the bulk solvent. Molecular dynamics simulations of modified TIP3P water molecules confined within channel-like cavities have been performed and the
