Objective(s): Heart failure (HF) is one of the leading causes of death worldwide. Due to beneficial effects of stem cells, paracrine secretion of them has recently been used by researchers. The purpose of this study was to investigate the effects of intravenous injection (IV) of conditioned medium (CM) of human amniotic membrane-derived mesenchymal stem cell (MSC-CM) o...

HF radar systems are widely and routinely used for the measurement of ocean surface currents and waves. Analysis methods presently in use are based on the assumption of infinite water depth, and may therefore be inadequate close to shore where the radar echo is strongest. In this paper, we treat the situation when the radar echo is returned from ocean waves that interact with the ocean floor. S...

Very low concentrations (pg mL(-1) or sub-pg mL(-1) level) along with the high salinity are the main problems in determining trace metal contents in seawater. This problem is mainly considered for investigations of naturally occurring YLOID (Y and Lanthanides) and Zr and Hf in order to provide precise and accurate results. The inductively coupled plasma mass spectrometry (ICP-MS), both in high ...

heart failure (hf) is one of the main causes of death and disability in the world. the prevalence of hf in developed countries is between 1% and 2% of the adult population and approximately between 6% and 10% in the elderly, giving rise to high costs of care and treatment. indeed, in the united states, the direct and indirect costs exceeded 23 billion dollars in 2002.  hf is typically character...

Thermodynamic calculations for selected silicate-oxide-fluorite assemblages indicate that several commonly occurring fluorite-bearing assemblages are restricted to relatively narrow fo,-fF> fields at constant P-T. The presence of fayalite-ferrohedenbergite-fluorite-quartz *magnetite and ferrosalite-fluorite-quartz-magnetite assemblages in orthogneisses from Au Sable Forks, Wanakena and Lake Ple...

The permeability and coupled behavior of pore pressure and deformations play an important role in hydraulic fracturing (HF) modeling. In this work, a poroelastic displacement discontinuity method is used to study the permeability effect on the HF development in various formation permeabilities. The numerical method is verified by the existing analytical and experimental data. Then the propagati...

Vitamin D deficiency is common among the elderly with and without heart failure (HF). This study was designed to identify the degree of vitamin D deficiency among HF and Non- HF elderly with cardiovascular disease. In this study, fifty hospitalized elderly patients with HF (26 women and 24 men, age range 60-90 years) and fifty elderly without HF were randomly selected. The level of serum 25-hyd...
