Thanks to modern advances in the field of stroke genetics, many cases of cryptogenic stroke have been clarified; the discovery of new pathogenetic pathways might lead in the future to the development of preventive strategies and acute treatments [14], [15].
Dr. Marshall recently helped clarify a classic discovery 10 years ago of how the embryo "knows" left from right.
Nor is the relationship (if any) between the multiple impacts and the extinctions which accompanied the end of the Eocene clarified by this discovery.
The nature of the bound form was clarified through the discovery and synthesis (1947 50) of the compound pantetheine, which contains pantothenic acid combined with the compound thioethanolamine.
This discovery clarified Albert Einstein's fundamental ideas about Brownian motion (displayed by the continual motion of specks of dust in a fluid under the constant bombardment of surrounding molecules).
The identity of the trackmakers was greatly clarified upon the discovery in 1857 of the hind leg of a young Iguanodon, with distinctly three-toed feet, showing that such dinosaurs could have made the tracks.
The situation was further clarified by the discovery of lipid rafts (Simons and Ikonen 1997; Laude and Prior 2004).
This discovery clarified some of the previously noted similarities and interactions between the BRCA proteins and the FA family of proteins, including the shared hypersensitivity to mitomycin C and the finding that targeted inactivation of the BRCA2 protein in mice produced an FA-like phenotype [ 27].
The case is the latest effort by the courts to clarify whether scientific discoveries whose use may not be fully clear may be patented or not.
There are minor differences between the two species, including the higher number of teeth in N. lancensis, which lead some scientists to recommend keeping the two genera separate until further research or discoveries clarify the situation.
The discovery, along with Semenza's additional work clarifying the molecular mechanisms of oxygen regulation in cells, has far-reaching implications in understanding the impact of low oxygen levels in cancer, diabetes, coronary artery disease, and other conditions.
