Regarding our article on the association of androgen deprivation therapy (ADT) with increased Alzheimer’s disease risk, Bowen et al, Froehner and Wirth, Leow et al, and Brady et al highlight a number of significant considerations that will prove important in the design of future studies that investigate the association of ADT and Alzheimer’s disease. We agree with Bowen et al and Leow et al tha...

The absence of high velocity redshifted forbidden lines in classical T-Tauri stars (Appenzeller et al. 1984; Edwards et al. 1987) has long be taken as evidence of opaque circumstellar disks: disks which occlude the receding component of the stellar wind or outflow, allowing only the blueshifted emission to be observed. There has been some controversy in the literature recently as to whether a d...

Basic fibroblast growth factor (bFGF) is a growth factor with proangiogenetic properties. Elevated bone marrow (BM) and peripheral serum bFGF levels have been reported in patients with multiple myeloma (MM) 1-3 ; however, the source of bFGF in patients with MM is not completely elucidated. Recently, Bisping et al, 4 in line with others, 1 have reported that human myeloma cell lines (HMCLs) (RPM...

Nowadays we are living an era which is marked by efforts for originality, innovation, collaboration, accumulation of experience and integration with and through many inventions such as computers, the internet, and technologies that have facilitated knowledge sharing and communication among people. This research seeks to extend the existing literature on KMS and knowledge sharing by proposing a ...

Scyphomedusae undergo a predictable ontogenetic transition from a conserved, universal larval form to a diverse array of adult morphologies. This transition entails a change in bell morphology from a highly discontinuous ephyral form, with deep clefts separating eight discrete lappets, to a continuous solid umbrella-like adult form. We used a combination of kinematic, modeling, and flow visuali...

Et Tu, Torsten? This critique of my Economic Policy paper generates many emotions. It is certainly an honor for my research to be taken seriously by such an eminent scholar as my friend Torsten Persson. And while any publicity is good, a negative citation dominates a positive one. There is irony; I came up with the original idea in a hallway conversation with Harry Flam a few feet from Persson’...

A traditional view of the nature of species holds that populations within species maintain genetic cohesion through substantial intraspecific gene flow and that the whole genome of a species is protected from interspecific gene flow by strong reproductive isolation. Both aspects of this view have been challenged. Reproductive barriers between recently evolved species can be incomplete and perme...
