  Myocardial infarction (MI) and stroke are the first and third leading causes of death in the U.S.A. accounting for more than 1 in 3 deaths per annum. Despite interventional and pharmaceutical advances, the number of people diagnosed with heart disease is on the rise. Therefore, new clinical strategies are needed. Cell-based therapy holds great promise for treatment of these diseases and is currently under extensive preclinical as well as clinical trials. The source and types of stem cells for these clinical applications are questions of great interest. Human umbilical cord blood (hUCB) appears to be a logical candidate as a source of cells. hUCB is readily available, and presents little ethical challenges. Stem cells derived from hUCB are multipotent and immunologically naive. Here is a critical literature review of the beneficial effects of hUCB cell therapy in preclinical trials.

  The primary limitations on range and duration of all space missions have been dependent on the fuel supply of the craft. Even field leading concepts such as magnetoplasmadynamic thrusters do not address this reality in that they require a craft to carry a finite supply of propellant to be ionized, setting a hard limitation on duration and performance aspects of a mission. My proposed method of craft propulsion abandons the notion that we must carry along our fuel. Instead, a craft would utilize in-transit resources, namely the low temperature plasma disbursed by the Sun primarily concentrated in the Earth’s ionosphere, as its propellant. General principles behind this propulsion, including their governing equations, as well as an example, are covered. In addition, the overall feasibility and most promising applications of this method are discussed. Nomenclature • m = mass flow rate A = cross-sectional area V = craft velocity ρ = plasma density (collected) o P = total pressure * c = sonic velocity at throat * a = throat area p = plasma pressure
