We studied the effect of extremely low frequency (ELF) currents on gap junction intercellular communication (GJIC) mediated by connexin43 protein. Confluent monolayers of synovial fibroblasts (HIG-82) and neuroblastoma cells (5Y) were exposed in bath solution to 0-75 mA/m(2) (0-56 mV/m), 60 Hz. Single channel conductance, cell membrane current-voltage (I-V) curves, and Ca(2+) influx were measur...

We report on a set of 5 GHz Urumqi observations of the galaxy M82, made between August 2005 and May 2009. From the resulting flux densities, we detect a strong flare, starting in March or April and peaking in June 2008. We identify this flare with supernova SN 2008iz. The time sampling of the radio light curve allows us to obtain information on the precursor mass-loss rate, the strength of the ...

We present starburst models for far-infrared/sub-millimeter/millimeter (FIR/sub-mm/mm) line emission of molecular and atomic gas in an evolving starburst region, which is treated as an ensemble of non-interacting hot bubbles which drive spherical shells of swept-up gas into a surrounding uniform gas medium. These bubbles and shells are driven by stellar winds and supernovae within massive star ...

In this Letter, we report the discovery of a new bright radio transient in M82. Using the Very Large Array, we observed the nuclear region of M82 at several epochs at 22 GHz and detected a new bright radio source in this galaxy's central region. We find a flux density for this flaring source that is ∼ 300 times larger than the upper limits determined in previous observations. The flare must hav...

We present evidence for an expanding super-bubble in M 82 (diameter: 130 pc, expansion velocity: 45 km s ?1 , mass: 8 10 6 M). It is seen in the 12 CO (J = 1 ! 0), 12 CO(J = 2 ! 1), 13 CO(J = 1 ! 0) and C 18 O(J = 1 ! 0) lines. The superbubble is centred around the most powerful supernova remnant, 41.9+58. The CO observations show that the molecular superbub-ble already broke out of the disk. T...
