Ultrasmall gadolinium-based nanoparticles (GBNs) induce both a positive contrast for magnetic resonance imaging and a radiosentizing effect. The exploitation of these characteristics leads to a greater increase in lifespan of rats bearing brain tumors since the radiosensitizing effect of GBNs can be activated by X-ray microbeams when the gadolinium content(More)
This work aims to estimate the diffusivity and partitioning of glucose in the dermis and the viable epidermis of human skin. The partition coefficient of glucose between phosphate-buffered saline and dermis, tape-stripped epidermis (TSE), stratum corneum (SC), and split-thickness skin, was measured in vitro using human cadaver skin. Glucose permeability(More)
Microbeam radiation therapy (MRT), a preclinical form of radiosurgery, uses spatially fractionated micrometre-wide synchrotron-generated X-ray beams. As MRT alone is predominantly palliative for animal tumors, the effects of the combination of MRT and a newly synthesized chemotherapeutic agent JAI-51 on 9L gliosarcomas have been evaluated. Fourteen days(More)
Data mining, computer aided molecular modeling, descriptor calculation, genetic algorithm and multiple linear regression analysis techniques were combined together to generate predictive quantitative structure property relationship (QSPR) models explaining the formation of lecithin-based W/O microemulsions. Ninety-four microemulsion phase diagrams were(More)
Packet-switched communication of haptic data telepresence systems is characterized by high packet rates on the communication channel. The quality of the internet-based telepresence systems depend on the quality of the communication channel between the operator and the remote site, and the delay jitter in the data exchange. Perceptual based data reduction(More)
Among rodent models for brain tumors, the 9L gliosarcoma is one of the most widely used. Our 9L-European Synchrotron Radiation Facility (ESRF) model was developed from cells acquired at the Brookhaven National Laboratory (NY, USA) in 1997 and implanted in the right caudate nucleus of syngeneic Fisher rats. It has been largely used by the user community of(More)
Data mining, computer-aided molecular modeling, descriptor calculation and multiple linear regression techniques were utilized to produce statistically significant and predictive models for O/W and W/O microemulsions. The literature was scanned over the last 20 years, subsequently, 68 phase diagrams from eight different references were collected. Molecular(More)
BBN Technologies designed an algorithm called Swift Start for TCP to mitigate the start up problem. Some drawbacks face that algorithm. This paper introduces a modification to that algorithm then it will evaluate the modified swift start TCP congestion control algorithm analytically and by simulation and then it will compare between its performance with(More)
Microemulsions are physically stable oil/water clear dispersions, spontaneously formed and thermodynamically stable. They are composed in most cases of water, oil, surfactant and cosurfactant. Microemulsions are stable, self-preserving antimicrobial agents in their own right. The observed levels of antimicrobial activity associated with microemulsions may(More)
Microemulsions of both O/W and W/O types were formulated by using Brij76, Brij97 and Tween80 as nonionic surfactant and propanol or butanol as cosurfactant with isopropyl myristate oil and water. Low concentrations of sodium salts of hexanoic, decanoic, palmitic and stearic acids were added to the prepared microemulsions to assess their ability to enhance(More)
