Length changes of muscle fibers have previously been shown to result in a temporary reduction in fiber stiffness that is referred to as thixotropy. Understanding the mechanism of this thixotropy is important to our understanding of muscle function since there are many instances in which muscle is subjected to repeated patterns of lengthening and shortening. By applying sinusoidal length changes...

In this study, tretinoin microemulsion has been formulated based on phase diagram studies by changing the amounts and proportions of inactive ingredients, such as surfactants, co-surfactants and oils. The effects of these variables have been determined on microemulsion formation, particle size of the dispersed phase and release profile of tretinoin from microemulsion through dialysis membrane. ...

A model is proposed that considers aging and rejuvenation in a soft glassy material as, respectively, a decrease and an increase in free energy. The aging term is weighted by an inverse of characteristic relaxation time suggesting that greater mobility of the constituents induces faster aging in a material. A dependence of relaxation time on free energy is proposed, which under quiescent condit...

Two studies were undertaken to assess the efficacy and safety of three thixotropic nasal sprays (IQM11, IQM12, IQM13) on seasonal allergic rhinitis (SAR). The three nasal sprays differ only with respect to the emulsifying agent used in the formulation. In the prospective, randomized, cross-over pilot study, 16 patients with a history of SAR received 2 x 0.14 ml IQM11 per nostril or no treatment...

We have shown in previous work that the addition of small quantities of colloidal silica to the UVcurable polymer coating of fused silica optical fiber causes a dramatic improvement in the fatigue and aging resistance both in aqueous and in constant humidity environments. The presence of silica in the coating inhibits the mechanisms responsible for the surface roughening that causes the fatigue...

We demonstrate refinements of a simple elastic-viscous-plastic rheological model with the addition thixotropic term to better flow human blood. The alteration this will contribute representation lightly structured complex materials. (EVP) framework requires thixotropy for more accuracy in fitting and predicting thixo-elasto-visco-plasticity flows microstructure. performance added features by co...

The aim of this research was to study the feasibility defatted wheat germ flour (DWGF) alone or in combination with xanthan gum (XG) as egg yolk substitutes mayonnaise formulation. In research, DWGF used at different levels (0, 25, 75 and 100%) XG (0.2%) substitutes. effects these substitutions on stability, textural rheological characteristics were investigated. According results, can be an su...
