A New Look at an Old Idea

Traditionally, most cases of hypertension in children and adolescents have been attributed to secondary causes, with renal and cardiac disorders being the most common, at least in preadolescent children. However, most hypertensive adolescents have no identifiable underlying cause for their hypertension, perhaps with the exception of obese adolescents, in whom the hypertension is likely attribut...

First practical applications, however, were not considered before 1990 when Bingham’s famous paper appeared which pointed out the great attraction of this idea – especially in the form of the FFT-based ”OFDM” (Orthogonal Frequency Division Multiplexing). Meanwhile, OFDM is applied in the DAB and DVB standard (Digital Audio/Video Broa...

On the cells of origin of radiogenic thyroid cancer: new studies based on an old idea.

We have presented evidence that the functional thyroid follicles (follicular units, FU) which are formed in grafts of monodispersed rat thyroid cells, and hence the thyroid tumors which later develop in such grafts, are clonal in origin. Transplantation assays indicate that the clonogens comprise approximately 1% of the cells in monodispersed suspensions of normal thyroid tissue. Carcinogenesis...
