We present a one-parameter family of approximation schemes, which we refer to as local maximumentropy approximation schemes, that bridges continuously two important limits: Delaunay triangulation and maximum-entropy (max-ent) statistical inference. Local max-ent approximation schemes represent a compromise—in the sense of Pareto optimality—between the competing objectives of unbiased statistica...

Almost 30 years after its first description, HIV still remains a global pandemic. The present paper aims to review the current knowledge on the ear, nose and throat (ENT) manifestations of HIV infection, and present the available diagnostic and treatment options. A literature review was conducted in Medline and other available database sources. Information from related books was also included i...

The title compound, C(26)H(34)O(9), a natural ent-kaurane diterpenoid, is composed of four rings with the expected cis and trans junctions. In the crystal structure, the mol-ecules stack along the a axis and are linked together by inter-molecular O-H⋯O hydrogen bonds.

A route for the degradation of the side chain of ent-labdane derivatives has been devised, giving the useful synthon 2beta,12-dihydroxy-13,14,15,16,17-pentanor-ent-labdane-8-one (8). The use of this compound in the preparation of terpenylquinone derivatives shall be reported elsewhere. In addition we have synthesized the compound 2beta,12-diacetoxy-8beta,17-epoxy-13,14,15,16-tetranor-ent-labdan...

Immunodiffusion experiments were conducted to associate a precipitin line with Escherichia coli heat-labile enterotoxin (LT). Wild strains of porcine and of human enteropathogenic E. coli as well as laboratory-derived enterotoxigenic variants of E. coli K-12 were used for LT antigen preparations. These were produced mainly by ultrafiltration and ammonium sulfate precipitation of broth culture s...

Electrically evoked otoacoustic emissions are sounds emitted from the inner ear when alternating current is injected into the cochlea. Their temporal structure consists of short- and long-delay components and they have been attributed to the motile responses of the sensory-motor outer hair cells of the cochlea. The nature of these motile responses is unresolved and may depend on either somatic ...

UNLABELLED ENT problems are the most common reason for a visit to a doctor in both rural and urban communities. In many developing countries, there is a lack of ENT specialists and overburdened hospital facilities. To date, there is no comprehensive study that has evaluated the spectrum of ENT disorders in a rural community. METHODS A prospective study was done for a period of three years to ...

To probe the pathway and specificity of cholesterol absorption, the synthetic enantiomer of cholesterol (ent-cholesterol) and cholesterol were labeled with deuterium, gavaged into hamsters, and measured by negative ion mass spectrometry. Initial uptake of both tracers into the intestinal mucosa at 30 min was similar but cholesterol was temporarily retained there, whereas mucosal ent-cholesterol...
