Previous studies with the mammalian brain have shown that the expression of a number of neuronal microtubule-associated proteins (MAPs) is developmentally regulated. For example, the low-molecular-weight form of MAP2 (MAP2c) is abundant in neonatal rat brains and is less abundant in adults. Similarly, MAP5 levels decrease during postnatal development. Using monoclonal antibodies, we have follow...

We investigated changes in mRNA expression of the somatotropic, thyrotropic, and corticotropic axes of Langshan (LS) and Arbor Acres (AA) broiler chickens during embryonic and postnatal development. We found an inverse expression profile between pituitary growth hormone (GH) and hepatic GH receptor mRNA [postnatal d (P)28 to P42], insulin-like growth factor (IGF)-I, and IGF-IR (P0 to P42), resp...

Abstract Actinomycetes, as the main producers of a variety active metabolites and enzymes, have received extensive attention in aquaculture. An actinomycete had been isolated from Haizhou Bay identified by morphological analysis 16S rRNA sequencing. Results showed that highest similarity (99.65%) with Nocardiopsis sp. was named strain E10. Strain E10 produced an exo-enzyme proteinase effect str...

This paper presents an evolutionary growth theory that captures the interplay between the evolution of mankind and economic growth since the emergence of the human species. This uni"ed theory encompasses the observed evolution of population, technology and income per capita in the long transition from an epoch of Malthusian stagnation to sustained economic growth. 2001 Elsevier Science B.V.

In the study of conjecture on M-theory as a non-linear realization E11/K11 we present arguments for the following: 1)roots of K11 coincide with the roots of Kac-Moody algebra EE11 with Dynkin diagram given in the paper, 2)one of the fundamental weights of EE11 coincides with l1 weight of E11, known to contain 11d supergravity brane charges. The statement 1) is extended on E10 and E9 algebras. E...

Mode division multiplexing (MDM) is a promising technology for the capacity enlargement of optical transmission network. As key element in MDM system, mode converter plays an important role signal processing. In this work, wideband E00-E10 silicon constructed by Y-branch and cascaded multimode interference coupler demonstrated. The theoretical crosstalk less than –29.2 dB within wavelength rang...
