Neural stem cells (NSCs) are defined by their ability to self-renew and to differentiate into mature neuronal and glial cell types. NSCs are the subject of intense investigation, owing to their crucial roles in neural development and adult brain function and because they present potential targets for gene and cell replacement therapies following injury or disease. Approaches to specifically gen...

Are transaction costs and half-lives between two cities the same in both directions traditional city-based monetary systems? Market conditions political circumstances may not justify this assumption; we provide evidence that it does hold 1825-1885 period Spain. Moreover, show empirical market integration Spain from 1875 to 1885 was a slow process of unification with decreasing costs, very ineff...

Ultraviolet imaging of the remnant of Supernova 1885 in M31 with the Hubble Space Telescope using the F255W filter on the WFPC2 reveals a dark spot of Fe II absorption at the remnant’s known position in the bulge of M31. The diameter of the absorbing spot is 0. 55 ± 0. 15, slightly smaller than, but consistent with, the 0. 70 ± 0. 05 diameter measured in the higher quality WFPC2 Ca II absorptio...

The suggestion that micro-organisms are responsible for the decomposition of cellulose in the alimentary canal (Wildt, 1874; Zuntz, 1879; Duclaux, 1882) arose from the proof (Henneberg & Stohmann, 1860-4) that it is, in fact, cellulose which disappears during the pa#sage of crude fibre through the animal (Haubner, 1855). Tappeiner (1882, 1883, 1884, 1888), who was the first to investigate the f...

Iiie regiment was stationed at Thayetmyo (Burma) from 1st January 1884? to 19th "January 1885. During tlii.s period there were 5 admissions for beri-beri.

Near UV HST images of the remnant of SN 1885 (S And) in M31 show a 0. 70 ± 0. 05 diameter absorption disk silhouetted against M31’s central bulge, at SN 1885’s historically reported position. The disk’s size corresponds to a linear diameter of 2.5 ± 0.4 pc at a distance of 725 ±70 kpc, implying an average expansion velocity of 11000 ± 2000 kms over 110 years. Low-dispersion FOS spectra over 320...
