This study examined the effects of mist generated from NaCl solution on electrochemical properties polymer electrolyte membrane fuel cells. Mist-containing Na+ and Cl- ions were using a custom-made generator. The current density-voltage-power density curves impedance spectroscopy cells systematically achieved. Furthermore, long-term stability experiments carried out chronoamperometry mode for 2...

prevention of medication errors in neonatal intensive care units (nicus) is of paramount importance due to age-specific and physiological conditions of neonates. this study aimed to evaluate the risk of medication prescription and administration via failure mode and effects analysis (fmea), which was carried out at the research and medical teaching center of imam reza hospital in mashhad, iran....

Drought stress in tropical dry forests is thought to result in greater asexual regeneration via vegetative sprouting (e.g., basal, root, and branch layering) than occurs in moister tropical forests. We tested this hypothesis by examining the prevalence of tree sprouting and seeding in tropical forests located along a rainfall gradient on the island of Hawai’i. Additionally, we examined the pote...

When complementary fragments of the imaginal wing disc of Drosophila are cultured for several days prior to inducing metamorphosis, usually one fragment will regenerate while the second duplicates. It has been proposed that wound healing plays an important part in disc regulation by initiating cell proliferation and determining the mode of regulation (regeneration/duplication). To test the latt...

In the present work, thermal regeneration of activated carbons (AC) was carried out at 1123 K and under N2 atmosphere. Experiments have been carried out using a single mode microwave device operating at 2450 MHz and a conventional electric furnace (EF) so as to compare the effect of the different heating mechanisms on the adsorptive capacities of the regenerated AC. The adsorbents were saturate...

Adult Neural Stem Cells (aNSCs) generate new neurons that integrate into the pre-existing networks in specific locations of the Vertebrate brain. Moreover, aNSCs contribute with new neurons to brain regeneration in some non-mammalian Vertebrates. The similarities and the differences in the cellular and molecular processes governing neurogenesis in the intact and regenerating brain are still to ...

The interconversion of cell lineages via transdifferentiation is an adaptive mode of tissue regeneration and an appealing therapeutic target. However, its clinical exploitation is contingent upon the discovery of contextual regulators of cell fate acquisition and maintenance. In murine models of diabetes, glucagon-secreting alpha cells transdifferentiate into insulin-secreting beta cells follow...

BACKGROUND The neonatal heart possesses the unique power to regenerate in response to resection of the left ventricular apex. We sought to determine whether the type of injury affects the mode of repair and regeneration. METHODS AND RESULTS Apical resection, or permanent left anterior descending coronary artery ligation, was induced in neonatal 1-day-old mice. Echocardiography was used to con...

objective(s): a novel iq-specttm method has become widely used in clinical studies. the present study compares the quality of myocardial perfusion images (mpi) acquired using the iq-specttm (iq-mode),conventional (180° apart: c-mode) and l-mode (90° apart: l-mode) systems. we assessed spatial resolution, image reproducibility and quantifiability using various physical phantoms. materials and me...
