A vital step in growth factor-driven angiogenesis is the coordinated engagement of endothelial integrins with the extracellular matrix. The molecular mechanisms that partner growth factors and integrins are being elucidated, revealing an intricate interaction of surface receptors and their signaling pathways.

Tiny dancers: the integrin–growth factor nexus in angiogenic signaling

Blood vessel formation is a dynamic process that involves interactions between soluble mediators, adhesive substrates, and endothelial cell surface receptors. Endothelial cell activation is a necessary first step in angiogenesis, which triggers the recruitment of smooth muscle cells and pericytes to newly formed vessels. Two growth factor families activate this initiating pathway in angiogenesi...

Agents, actions, mental organisms and anigrafs are often confused because the definitions are not precise. A reductionist distinction is that an action is initiated by an agent, whereas a mental organism coordinates a sequence of actions carried out by several agents. An anigraf shows the relations among the goal states for agents or mental organisms, but is sometimes used to identify a group o...

Iliopsoas Syndrome in Dancers

BACKGROUND Coxa saltans refers to a constellation of diagnoses that cause snapping of the hip and is a major cause of anterior hip pain in dancers. When the internal type is accompanied by weakness or pain, it is referred to as iliopsoas syndrome. Iliopsoas syndrome is the result of repetitive active hip flexion in abduction and can be confused with other hip pathology, most commonly of labral ...
