To assess the status of global climate models (GCMs) in simulating upper-tropospheric ice water content (IWC), a new set of IWC measurements from the Earth Observing System’s Microwave Limb Sounder (MLS) are used. Comparisons are made with ECMWF analyses and simulations from several GCMs, including two with multi-scale-modeling framework. For January 2005 monthly and daily mean values, the spat...
Previous work has shown that the sim gene of bacteriophage P1, if cloned into a multicopy vector, confers immunity against P1 infection to cells. We show that a 1.85-kb DNA fragment from the sim region of P1 (in the multicopy plasmid pMK4) expresses immunity and encodes three proteins with molecular weights of about 25, 24, and 15 kDa. Deletion of 650 bp from the sim region abolished synthesis ...
Purpose: Besides cholesterol lowering effects, simvastatin (SIM) at very high doses possesses antitumor actions. Moreover our previous studies demonstrated that tumor-targeted delivery of SIM by using long-circulating liposomes (LCL) improved the therapeutic index of this drug in murine melanoma-bearing mice. To evaluate whether this finding can be exploited for future therapy of colorectal can...
Obstructive jaundice, owing to biliary obstruction, has been illustrated to trigger various biochemical, histological and immunological changes, leading to liver damage or even failure. The detailed molecular mechanism of simvastatin (Sim) involvement in liver regeneration during obstructive jaundice progression remains poorly elucidated. In the present study, an acute obstructive jaundice rat ...
The Space Interferometry Mission (SIM) will make precise astrometric measurements that can be used to detect planets around nearby stars. We have simulated SIM observations and estimated the ability of SIM to detect planets with given masses and orbital periods and measure their orbital elements. We combine these findings with an estimate of the mass and period distribution of planets determine...
POLICY ACTION ON CLIMATE CHANGE IS INFORMED BY CLIMATE MODEL projections as described most recently in the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC). The models used are general circulation models (GCMs), which numerically represent the physical climate system in three dimensions, including the hydrological cycle. These are complemented by recently de...
Climate simulations performed with general circulation models (GCMs) are widely viewed as the principal scientific basis for developing policies to address potential future global change scenarios (e.g. global warming, ozone depletion, changes in land use, etc.). Hence, there is a compelling need to systematically improve the performance of GCMs in simulating the present climate, and thereby to...
