In the developing spinal cord, most oligodendrocyte precursors (OLPs) arise from the ventral ventricular zone (VZ) under the influence of Sonic Hedgehog, but a minority are generated from the dorsal VZ in a Hedgehog-independent manner. In the developing forebrain too, OLPs arise from both the ventral and the dorsal VZ. It is not known whether dorsally and ventrally derived oligodendrocyte (OL) ...

Using panel cointegration techniques, we show a cointegrating relationship exists between capital and productivity in 446 manufacturing industries. Panel DOLS and FMOLS estimates reveal that innovations to productivity increase and Granger cause capital movements.  2000 Elsevier Science S.A. All rights reserved.

Hemiasterlin (Hem) and dolastatin (Dol) are marine natural products which are cytotoxic for cancer cells. Hem, a tripeptide, and Dol, a hexapeptide, were conjugated with linkers (L) to the universal BB agonist DPhe-Gln-Trp-Ala-Val-betaAla-His-Phe-Nle-NH2(BA1) and the effects of the Hem-BB and Dol-BB conjugates investigated on NCI-H1299 lung cancer cells. Hem-LA-BA1 and Hem-LB-BA1 inhibited spec...

When compared with the Mental Capacity Act (MCA) 2005, the Mental Health Act (MHA) 1983 seems an outlier. It authorises compulsory treatment of mental disorders on the basis of P's risks. English law, therefore, discriminates between mental and physical disorders. Following the UK's ratification of the Convention on the Rights of Persons with Disabilities (CRPD), the MHA probably also violates ...

This paper employs recently developed techniques for testing hypotheses in cointegrated panels to test the strong version of purchasing power parity for a panel of post Bretton Woods data. We compare results using fully modiŽ ed and dynamic OLS approaches , and strongly reject the hypothesis . We also introduce a new between-dimensio n dynamic OLS estimator and Ž nd that the between-dimensio n ...
