Biophysical Characteristics Reveal Neural Stem Cell Differentiation Potential
Distinguishing human neural stem/progenitor cell (huNSPC) populations that will predominantly generate neurons from those that produce glia is currently hampered by a lack of sufficient cell type-specific surface markers predictive of fate potential. This limits investigation of lineage-biased progenitors and their potential use as therapeutic agents. A live-cell biophysical and label-free measure of fate potential would solve this problem by obviating the need for specific cell surface markers

Pseudotumor of the Mandible as First Presentation of Hemophilia in a 2-Year-Old Male: A Case Report and Review of Jaw Pseudotumors of Hemophilia
Pseudotumor of hemophilia (PTH) is a rare complication seen in approximately 1–2% of cases of hemophilia. Although much more common in long bones, the pelvis, and small bones of the hands and feet than in the jaws, occasionally hemorrhage in the jaws occurs with this result. We present a case in a two-year-old male with a one-month swelling of the right mandible without significant medical history or diagnosis of hemophilia who was subsequently diagnosed as having Factor IX deficiency, or hemophilia B. A review of the literature revealed only 15 reported cases of PTH of the jaws and salient features of PTH in the jaws are discussed. The differential diagnosis of masses occurring in the jaws of children is limited and PTH should be considered when a mass presents with rapid growth and the histopathologic features are not diagnostic for a neoplastic process, even in the absence of a prior diagnosis of hemophilia as PTH may be the initial manifestation of this disease
Growth, Decay and Structural Change
We attempt to show the historically unique situation in which mankind now finds itself, which forces are working and what may be expected in the future. These general considerations are then used to study economic development up to the year 2000. The driving forces are identified and their development explained by a latent variable called “degree of economic activity”. This chapter provides the philosophical background for the understanding of the following chapters
