Assessment of molecular modulation by multifrequency electromagnetic pulses to preferably eradicate tumorigenic cells.

Physics methods of cancer therapy are extensively used in clinical practice, but they are invasive and often confront undesired side effects. A fully new equipment that allows sustained emission of intense and time-controlled non-ionizing multifrequency electromagnetic pulse (MEMP), has been applied to eukaryotic cells in culture. The equipment discriminates the overall electronegative charge of the cell cultures, and its subsequent proportional emission may thereby become higher and lethal to cancer cells of generally high metabolic activity.

Synthesis of N-Sulfopropylated Hyperbranched Polyethyleneimine with Enhanced Biocompatibility and Antimicrobial Activity.

Hyperbranched polyethyleneimine having 25,000 Da molecular weight was functionalized by a simple sulfopropylation reaction, affording a novel N-sulfopropylated PEI derivative (PEI-SO ). The successful introduction of N-sulfopropyl and sulfobetaine groups to the amino groups of PEI was spectroscopically confirmed. Furthermore, the antibacterial and anti-cyanobacterial activity of PEI-SO in comparison to the parent PEI were investigated on two type heterotrophic bacteria, i.

Sustainability Planning for a Community Network to Increase Participation in Evidence-Based Lifestyle Change Programs: A Mixed-Methods Approach.

Community-based chronic disease prevention programs can have long-term, broad public health benefits. Yet, only 40 to 60% of evidence-based health programs are sustained. Using established frameworks and evidence-based tools to characterize sustainability allows programs to develop structures and processes to leverage resources effectively to sustain effective program activities and systems.

Salt and heat stress enhances hydrogen production in cyanobacteria.

Cyanobacteria are among the most suitable organisms for the capture of excessive amounts of CO and can be grown in extreme environments. In our research we use the single-celled freshwater cyanobacteria Synechococcus elongatus PCC7942 PAMCOD strain and Synechocystis sp. PCC6714 for the production of carbohydrates and hydrogen.
