MICE WERE INJECTED INTRAPERITONEALLY WITH ONE OF THE FOLLOWING BACTERIAL PRODUCTS HAVING ENDOTOXIN ACTIVITY: pertussis vaccine, a suspension of heat-killed cells of Klebsiella pneumoniae (type C), or a purified lipopolysaccharide prepared from cultures of Salmonella typhosa. Following treatment with either one of these materials, the animals were infected intravenously with virulent cultures of...

A synthetic approach to the heterodimeric bisindole alkaloid leucophyllidine is disclosed herein. An enantioenriched lactam building block, synthesized through palladium-catalyzed asymmetric allylic alkylation, served as precursor both hemispheres. The eburnamonine-derived fragment was a Bischler–Napieralski/hydrogenation approach, while eucophylline-derived by Friedländer quinoline synthesis a...

This study was undertaken to evaluate the in vitro activities of arbekacin-based combination regimens against vancomycin hetero-intermediate Staphylococcus aureus (hetero-VISA). Combinations of arbekacin with vancomycin, rifampin, ampicillin-sulbactam, teicoplanin, or quinupristin-dalfopristin against seven hetero-VISA strains and two methicillin-resistant S. aureus strains were evaluated by th...

In₂O₃/SnO₂ composite hetero-nanofibers were synthesized by an electrospinning technique for detecting indoor volatile organic gases. The physical and chemical properties of In₂O₃/SnO₂ hetero-nanofibers were characterized and analyzed by X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), Energy Dispersive X-Ray Spectroscopy (EDX), specific surface Brunauer-Emmett-Tell...

We describe respiration monitoring in sleep using hetero-core fiber optic pressure sensors. The proposed hetero-core fiber optic sensor is highly sensitive to macrobending as a result of the core diameter difference due to stable single-mode transmission. Pressure sensors based on hetero-core fiber optics were fabricated to have a high sensitivity to small pressure changes resulting from minute...

We addressed the evolutionary trace of hetero-oligomer interfaces by comparing the structures of paralogous proteins; one of them is a monomer or homo-oligomer and the other is a hetero-oligomer. We found different trends in amino acid conservation pattern and hydrophobicity between homo-oligomer and hetero-oligomer. The degree of amino acid conservation in the interface of homo-oligomer has no...

1. The meningococcus polysaccharide reacts with a broad precipitable carbohydrate antibody in common with those of B. anthracis, B. subtilis, B. proteus and B. mesentericus. 2. The anthrax and proteus polysaccharides are specific in the higher dilutions of serum. 3. Antianthrax serum contains two different polysaccharide precipitable antibodies, one specific and the other non-specific. 4. Agglu...
