OBJECTIVE Obesity promotes macrophage infiltration into adipose tissue and is associated with increases in several cardiovascular diseases. Infusion of angiotensin II (AngII) to mice induces formation of abdominal aortic aneurysms (AAAs) with profound medial and adventitial macrophage infiltration. We sought to determine whether obesity promotes macrophage infiltration and proinflammatory cytok...

Dr. Jo Ellen Roseman and Mary Koppal, from the American Academy for the Advancement of Science (AAAS), discuss how brain science fits into national classroom curricula. While recommendations published by AAAS, the National Research Council, the Society for Neuroscience, and the College Board all include standards relating to the brain, what students actually learn in the classroom varies greatl...

The manner in which boundary conditions are approximated and introduced into finite-difference schemes has an important influence on the stability and accuracy of the results. The standard von Neumann stability condition applies only for points which are not in the vicinity of the boundaries. This stability condition does not take into consideration the effects caused by introducing the boundar...

Fragment production has been studied as a function of the source mass and excitation energy in peripheral collisions of 35 Cl+ 197 Au at 43 MeV/nucleon and 70 Ge+ nat Ti at 35 MeV/nucleon. The results are compared to the Au+Au data at 600 MeV/nucleon obtained by the ALADIN collaboration. A mass scaling, by A source ∼ 35 to 190, strongly correlated to excitation energy per nucleon, is presented,...
