This image is the only photograph of its kind to date, showing a fully sunlit hemisphere of the Earth. Earth (or, "the earth") is the only planet presently known to support life, and its natural features are the subject of many fields of scientific research. Within the solar system, it...

Axial FLAIR shows an inhomogeneous lesion in the right hemisphere with associated oedema, mass effect, and compression of the ventricle (2A), with irregular, peripheral enhancement can be detected on post-contrast T1WI (2B). On DWI/ADC, areas with low cellularity, as well as areas with high ...
In the central nervous system, administration of sCR1 in rats resulted in a 40% decrease in brain neutrophil accumulation in the traumatized hemisphere as compared to normal controls[52, 78]. sCR1 was first studied in myocardial infarction[79] and it has been suggested as a therapy to ...
