Emulsions are commonly used in foods, pharmaceuticals and home-personal-care products. For emulsion based products, it is highly desirable to control the droplet size distribution to improve storage stability, appearance and in-use property. We report preparation of uniform-sized silicone oil microemulsions with different droplets diameters (1.4-40.0 μm) using SPG membrane emulsification techni...

The aim of the present study was to investigate the influence and the mechanisms of cineole and terpineol on the in-vitro transdermal delivery of huperzine A from microemulsions, and their potential synergistic effect on the permeation enhancement. The transdermal delivery of huperzine A from microemulsions with different concentrations of cineole and terpineol through the rat abdominal skin wa...

RESUMO Introdução: várias técnicas de reperfusão foram desenvolvidas a fim reduzir o dano da lesão induzida por isquemia-reperfusão. Este estudo objetivou avaliar retrograda (RR) comparado com anterógrada (AR), e sem realização técnica lavagem do enxerto (WO). Métodos: coorte prospectiva 94 transplantes ortotópicos fígado doador falecido divididos em três grupos: RR WO (RR+WO), (AR+WO), AR (AR)...

The paper presents geometric models of the set WO of weak orders on a finite set X. In particular, WO is modeled as a set of vertices of a cubical subdivision of a permutahedron. This approach is an alternative to the usual representation of WO by means of a weak order polytope.

Microemulsions (μe) with water and a hydrophobic ionic liquid (IL) usually require 45-60 wt% surfactant to solubilize equal amounts of water and IL. To increase the efficiency we designed a new class of surfactants by combining a hydrophilic but IL-ophobic carbohydrate-based part with a hydrophobic but IL-ophilic IL-based part. These surfactants allow formulating microemulsions with 20 wt% surf...

Concentration ratios (CR(wo-media)) are used in most radioecological models to predict whole-body radionuclide activity concentrations in wildlife from those in environmental media. This simplistic approach amalgamates the various factors influencing transfer within a single generic value and, as a result, comparisons of model predictions with site-specific measurements can vary by orders of ma...

The ability to induce morphological transitions in water-in-oil (w/o) and water-in-CO2 (w/c) microemulsions stabilized by a trichain anionic surfactant 1,4-bis(neopentyloxy)-3-(neopentyloxycarbonyl)-1,4-dioxobutane-2-sulfonate (TC14) with simple hydrotrope additives has been investigated. High-pressure small-angle neutron scattering (SANS) has revealed the addition of a small mole fraction of h...

WO,/ZrO, catalysts prepared by different methods are distinct in their catalytic behaviour. In this work, WO,/ZrO, catalysts prepared by impregnating Zr(OH), and crystallized ZrO, and then calcining at selected temperatures were characterized by means of qualitative and quantitative Raman spectroscopy. The results showed that ZrO, in WO,/ZrO, obtained from crystallized ZrO, (referred to as WZ) ...

Methods for expressing a heteromeric taste receptor that responds to umami taste stimuli are provided. These methods comprise the co-expression of T1R1 and T1R3 nucleic acid sequences in a host cell that desirably also expresses a G protein that couples therewith, e.g., G.sub..alpha.15 and G.sub..alpha.16 or gustducin. In preferred embodiments, the host cells will be mammalian cells or Xenopus ...
