zygophyllum atriplicoides is one of the important species of iran rangelands that has special importance owing to some properties like high distribution rate, coverage percentage, density, and plant biomass that make it possible to supply a part of forage needed by livestock during spring and winter as well as to avoid soil degradation against water and wind erosions. this research tries to stu...

BACKGROUND Akt/protein kinase B signaling pathway has been implicated in tumorigenesis and progression. Previous studies showed the predictive potential of p-Akt-1, but total Akt-1 could provide more reliable information. We used image deconvolution, nanotechnology (quantum dots), and image analysis to improve Akt-1 quantification. DESIGN This tissue microarray study included 840 radical pros...

The practice of executive stock option repricing is examined using a sample of firms in the gaming industry during 1994-98. The practice of repricing executive stock options is often criticized, however this paper recognizes that there may be conditions when such recontracting may be viewed as beneficial to shareholders.

OBJECTIVE To determine risk factors among licensed firearm retailers for disproportionate sales of handguns that are later subjected to ownership tracing, generally after use in crime. DESIGN Case-control; the study period was 1998-2003. Cases were all eligible firearm retailers whose handguns were later traced at a rate that significantly (p<0.05) exceeded the expected value. Controls were a...

Recent molecular evidence suggests that Sciurus vulgaris populations from Calabria (southern Italy) are distinct from those occurring in northern and central Italy. Here, we re-analyzed using multivariate and univariate techniques an historical dataset provided by Cavazza (1913), who documented measurements for the now extinct squirrel population from Campania. Both univariate and multivariate ...
