BACKGROUND Prolongation of action potential duration (APD), increased spatial APD dispersion, and triangulation are major factors promoting drug-induced ventricular arrhythmia. Preclinical identification of HERG/IKr-blocking drugs and their pro-arrhythmic potential, however, remains a challenge. We hypothesize that transgenic long-QT type 1 (LQT1) rabbits lacking repolarizing IKs current may he...

purpose: to determine the indications for and surgical techniques of corneal transplantation at labbafinejad medical center (lmc) from 2004 to 2007. methods: in this descriptive study, records of 756 patients who had undergone corneal transplantation from october 2004 to october 2007 were reviewed. results: overall, 504 male (64.9%) and 272 female (35.1%) subjects with mean age of 41.29±21.25 (...

We use the APOSTLE $\Lambda$CDM cosmological hydrodynamical simulations of Local Group to study recent accretion massive satellites into halo Milky Way (MW)-sized galaxies. These systems are selected be close analogues Large Magellanic Cloud (LMC), most satellite MW. The allow us address, in a context, impact Clouds on MW, including contribution MW population, and constraints placed Galactic po...

Context. The structural parameters of the disk of the Large Magellanic Cloud (LMC) are estimated. Aims. We used the JH photometric data of red clump (RC) stars from the Magellanic Cloud Point Source Catalog (MCPSC) obtained from the InfraRed Survey Facility (IRSF) to estimate the structural parameters of the LMC disk, such as the inclination, i, and the position angle of the line of nodes (PAlo...

We report detections of J=2–1 line emission from the carbon monoxide isotopomers 13CO, C18O and C17O in the molecular clouds N159W, N113, N44BC, and N214DE in the Large Magellanic Cloud (LMC). 13CO and C18O lines were observed in two additional clouds: N159S in the LMC and N27 in the Small Magellanic Cloud (SMC). While 13CO was detected in both of them, only upper limits to the C18O line emissi...

We selected cepheids from the OGLE database for the Magellanic Clouds in the period range 10 ≤ P ≤ 10 days. There were 33 objects in the LMC and 35 in the SMC. We find that the median amplitude of cepheids in the LMC is 18% larger than in the SMC, a 4 σ effect. This implies that the period flux amplitude relation is not universal, and cannot be used to measure distances accurately. Subject head...

A general review is given of the calibration of the Cepheid distance scale, with particular reference to its use in the determination of H0. Emphasis is placed on the advantage of using a galactic calibration of the Cepheid scale, rather than relying on an adopted distance to the LMC. It is then possible to use LMC data to test for possible metallicity effects on this scale.

The discovery of the Sgr dwarf galaxy shows that the Galactic halo contains large clumps which are not full viralized. This may change implications of observed microlensing events towards the LMC. If more than one such systems are hidden in the Galactic halo, then given their enormous angular size, there is a significant chance for any line of sight, say the LMC direction, to intersect one of t...
