Differentiation Of Murine Erythroleukemic Cells During Exposure To Microwave Radiation

Cultures of murine erythroleukemic cells undergoing erythroid differentiation in response to induction by hexamethylene bisacetamide (HMBA) were exposed to 1180-MHz microwave (MW) radiation for 48 h while maintained at 37.4°C by variable-temperature air flow. Exposures at 1180 MHz were at 5.5, 11, and 22 mW/cm2 with a normalized specific absorption rate of 3.32 W/kg per mW/cm2. HMBA-induced control cells were incubated in a 37.4°C water bath. Mean cell doubling time was 16.5 h in both the irradiated cultures and the control cultures. About 65% of the cells of irradiated cultures and control cultures were benzidine-positive differentiated cells. Both the irradiated cultures and the control cultures contained approximately 58 μg of hemoglobin/mg total cytoplasmic protein. The absence of any change in these parameters suggests that MW radiation at 1180 MHz and similar frequencies exerts no effect on proliferation and differentiation of mammalian cells in the absence of hyperthermia

Angiogenic Effect of Bioactive Borate Glass Microfibers and Beads in the Hairless Mouse

The purpose of this project was to investigate the angiogenic mechanism of bioactive borate glass for soft tissue repair in a \u27hairless\u27 SKH1 mouse model. Subcutaneous microvascular responses to bioactive glass microfibers (45S5, 13-93B3, and 13-93B3Cu) and bioactive glass beads (13-93, 13-93B3, and 13-93B3Cu) were assessed via: noninvasive imaging of skin microvasculature; histomorphometry of microvascular densities; and quantitative PCR measurements of mRNA expression of VEGF and FGF-2 cytokines. Live imaging via dorsal skin windows showed the formation at two weeks of a halo-like structure infused with microvessels surrounding implanted borate-based 13-93B3 and 13-93B3Cu glass beads, a response not observed with silicate-based 13-93 glass beads. Quantitative histomorphometry of tissues implanted with plugs of 45S5, 13-93B3, and 13-93B3Cu glass microfibers revealed microvascular densities that were 1.6-, 2.3-, and 2.7-times higher, respectively, than the sham control values whereas 13-93, 13-93B3, and 13-93B3Cu glass beads caused the microvascular density to increase 1.3-, 1.6-, and 2.5-fold, respectively, relative to sham controls. Quantitative PCR measurements indicate a marginally significant increased expression of VEGF mRNA in tissues with 13-93B3Cu glass beads, an outcome that supported the hypothesis that copper-doped borate glass could promote VEGF expression followed by angiogenesis for enhanced wound healing

Scaffold for Tissue Regeneration in Mammals

A three-dimensional scaffold with interconnected pores for repair of tissue comprising a scaffold body for structural support of the tissue scaffold, where the scaffold body comprises scaffold body components bonded to each other and made from component materials comprising about 40 to about 90 wt % B2O3, and two or more other oxides, wherein the scaffold body has a porosity between about 15 and about 90 vol %

The Fire and Smoke Model Evaluation Experiment - A plan for integrated, large fire-atmosphere field campaigns

The Fire and Smoke Model Evaluation Experiment (FASMEE) is designed to collect integrated observations from large wildland fires and provide evaluation datasets for new models and operational systems. Wildland fire, smoke dispersion, and atmospheric chemistry models have become more sophisticated, and next-generation operational models will require evaluation datasets that are coordinated and comprehensive for their evaluation and advancement. Integrated measurements are required, including ground-based observations of fuels and fire behavior, estimates of fire-emitted heat and emissions fluxes, and observations of near-source micrometeorology, plume properties, smoke dispersion, and atmospheric chemistry. To address these requirements the FASMEE campaign design includes a study plan to guide the suite of required measurements in forested sites representative of many prescribed burning programs in the southeastern United States and increasingly common high-intensity fires in the western United States. Here we provide an overview of the proposed experiment and recommendations for key measurements. The FASMEE study provides a template for additional large-scale experimental campaigns to advance fire science and operational fire and smoke models

Repeated game theory as a framework for algorithm development in communication networks

This article presents a tutorial on how to use repeated game theory as a framework for algorithm development in communication networks. The article starts by introducing the basis of one-stage games and how the outcome of such games can be predicted, through iterative elimination and Nash equilibrium. In communication networks, however, not all problems can be modeled using one-stage games. Some problems can be better modeled through multi-stage games, as many problems in communication networks consist of several iterations or decisions that need to be made over time. Of all the multi-stage games, the infinite-horizon repeated games were chosen to be the focus in this tutorial, because optimal equilibrium settings can be achieved, contrarily to the suboptimal equilibria achieved in other types of game. With the theoretical concepts introduced, it is then shown how the developed game theoretical model, and devised equilibrium, can be used as a basis for the behavior of an algorithm, which is supposed to solve a particular problem and will be running at specific network devices.
