Polyethylene-oxide (PEO) linear nano-polymer directly stimulates endothelium and protects myocardium from focal ischemia-reperfusion injury via eNOS pathway in rats

Uryash A., Arias J., Wu H., Adams J.A., Mount Sinai Medical Center, US

Medical grade Nano-polymers (NP) used to enhance circulation, drug and gene delivery. Injection of Polyethylene-oxide (PEO) increase tissue perfusion and decrease mean blood pressure in animal models. Polyethylene-oxide (PEO) NP’s ultra high molecular weight (2-5 [...]

Leveraging Ontologies for Improved Medical Outcomes Assessment: Implementing Medical Management Technology to Drive Innovation

Little E., CTG Life Sciences, US

Sensor data - such as that produced by many kinds of nanotechnologies - can be difficult to manage and maintain. This is especially true in areas of biomedicine where contextual information is important to capture [...]

Computational Modeling of Electromagnetically Induced Heating of Magnetic Nanoparticle Materials for Hyperthermic Cancer Treatment

Rast L., Harrison J.G., University of Alabama at Birmingham, US

We present results on the computational modeling of electromagnetically induced heating for the purpose of hyperthermic cancer treatment with magnetic nanoparticle fluids. Magnetic hyperthermia can therefore be used for direct targeting and destruction of tumors [...]

Determination of the Electroporation Threshold for pulses from 95 ns to 20 us

Saulis G., Balevicius S., Saule R., Stankevic V., Zurauskiene N., Vytautas Magnus University, LT

The dependences of the fraction of electroporated mouse hepatoma MH-22A cells on the pulse intensity were obtained for the cells exposed to single square-wave electric pulses with the durations from 95 ns to 20 us. [...]

Analysis of the Relationships Between the Parameters of the Electric Pulse

Saulis G., Vytautas Magnus University, LT

Theoretical relationships between the parameters of the electric pulse which is necessary for the poration of the cell have been obtained. Analysis has been made for the square wave, exponential and sine wave ac electric [...]

Preparation and Characterization of Coenzyme Q10-Loaded Nanostructured Lipid Carriers as Delivery Systems for Cosmetic Component

Wang H., Xia Q., Southeast University, Nanjing, China, CN

Nanostructured Lipid Carrier (NLC) was a kind of nanosized carrier for lipophilic active compounds. Coenzyme Q10 (CoQ10) which is a versatile anti-oxidant is practically insoluble and chemically labile in water and should be incorporated in [...]

Bimolecules in multimodal and multifunctional bioimaging database: potentials and applications

Sharma A., Sharma R., Sharma A., Sharma R., Innovations and Solutions Inc., US

Oligonucleotides are biomarkers in gene expression imaging and proteins for imaging proteomics based on these end product molecules as visible by MRI and PET to give structural and metabolic information in diseased tissue. We compiled [...]

Bioluminescent quantum dots induced photodynamic therapy in vitro

Hsu C.Y., Lai P.S., Rao J.H., National Chung Hsing University, TW

Photodynamic therapy (PDT) is an innovative method for cancer treatment which involves the administration of a photosensitizing agent followed by exposure to the visible light. Appreciate light source to induce photosensitizing agent is the key [...]

Electrochemical Mechanics of Nanometer-Scaled Structural Layers of Bacterial Spores

Kazakov S.V., Pace University, US

The early events in the nutrient and non-nutrient germination of Bacillus subtilis spores are considered in combination with the properties of nanometer-scaled spore structural layers. All structural, not metabolically mediated, transformations at the early steps [...]

Traceability of Polyethylcyanoacrylate nanoparticles through the Startum Corneum

Diaz Torres R., National University of Mexico, MX

We followed nanoparticles through the stratum corneum using tape stripping and the nanoparticles quatification was done using photoluminescence. We found some interesting data at 3 hrs of application of nanoparticles because it seems like nanoparticles [...]
