چکیده
The wound-healing process has previously been modeled with exponential orwith linear curves. In the present study, we proposed a new model called the delayed exponential model, and compared all three models. Assessment of the models was based on healing data for two large groups of pressure ulcers in spinal-cord-injured (SCI) patients. The first group consisted of conventionally treated wounds and the second group of wounds additionally treated with biphasic electric-current-pulse stimulation, which was applied locally to the wound. Linear, exponential, and delayed exponential curves were fitted to experimental data (weekly measurements of the wound surface area). Numerical criteria, in the form of the least sum of squares of errors and goodness-of-fit, were calculated for each wound and model. Both numerical criteria showed that the delayed exponential model offers the best fit of the three models tested.

The effect of application of short, intense electric pulses on tumor blood volume was investigated using albumin-(Gd-DTPA)30 contrast-enhanced magnetic resonance imaging (MRI). One of paired SA-1 fibrosarcoma tumors implanted in each flank of NJ mice was treated with electric pulses. MRI was performed dynamically before and after intravenous administration of albumin-(Gd-DTPA)3o (0.02 mmol Gd/k...

Electrotherapy with low-level direct current (DC) can induce antitumor effects in various tumor models. Applied in combination with certain anticancer drugs, it can significantly increase their effectiveness. It has been suggested that the demonstrated effects of electrotherapy arise from its modification of tumor blood flow. The effect of such treatment on blood perfusion of solid subcutaneous...
متن کاملGains from diversification on convex combinations: A majorization and stochastic dominance approach
By incorporating both majorization theory and stochastic dominance theory, this paper presents a general theory and a unifying framework for determining the diversification preferences of risk-averse investors and conditions under which they would unanimously judge a particular asset to be superior. In particular, we develop a theory for comparing the preferences of different convex combination...
متن کاملImproved immunogenicity of tetanus toxoid by Brucella abortus S19 LPS adjuvant.
BACKGROUND Adjuvants are used to increase the immunogenicity of new generation vaccines, especially those based on recombinant proteins. Despite immunostimulatory properties, the use of bacterial lipopolysaccharide (LPS) as an adjuvant has been hampered due to its toxicity and pyrogenicity. Brucella abortus LPS is less toxic and has no pyrogenic properties compared to LPS from other gram negati...

A rigorous microscale electrokinetic model for hydrogel-colloid composites is adopted to compute macroscale profiles of electrolyte concentration, electrostatic potential, and hydrostatic pressure across membranes that separate electrolytes with different concentrations. The membranes are uncharged polymeric hydrogels in which charged spherical colloidal particles are immobilized and randomly d...
