Progress and prospect of mesenchymal stem cell-based therapy in atherosclerosis.

Atherosclerosis is a chronic inflammatory disease of the arterial intima, occurring usually in the aged populations who are suffering from hypertension, dyslipidemia and diabetes for a long time. Research on atherosclerosis has shown that macrophage foam cell formation, inflammation, dyslipidemia and immune cells infiltration are all involved in regulating the onset and progression of atherosclerosis. Mesenchymal stem cells (MSCs) originated from different kinds of tissue are a group of cells possessing well-established self-renewal and multipotent differentiation properties as well as immunomodulatory and anti-inflammatory roles.

An Evolutionary Computation Approach to Examine Functional Brain Plasticity.

One common research goal in systems neurosciences is to understand how the functional relationship between a pair of regions of interest (ROIs) evolves over time. Examining neural connectivity in this way is well-suited for the study of developmental processes, learning, and even in recovery or treatment designs in response to injury. For most fMRI based studies, the strength of the functional relationship between two ROIs is defined as the correlation between the average signal representing each region.
