A unified phylogeny-based nomenclature for histone variants
(BioMed Central, 2012-06-21)
Histone variants are non-allelic protein isoforms that play key roles in diversifying chromatin structure. The known number of such variants has greatly increased in recent years, but the lack of naming conventions for ...
The Neolithic of the Middle Nile Region: An Archeology of Central Sudan and Nubia
(Fountain Publishers, 2010)
The basic objective of this book is to develop earlier studies, in the light of comprehensive new data which has been found in the last 40 years in the Middle Nile Region. The book provides a summary and interpretation of ...
Trade and Wadis System(s) in Muslim Sudan
(Fountain Publishers, 2010)
The Sudan belt stretches from the east to west across Africa south of the Sahara. Despite divisions and the rivalries that caused them, there seems to have long been a remarkably free flow of people and ideas along the ...
Development of the larval anterior neurogenic domains of Terebratalia transversa (Brachiopoda) provides insights into the diversification of larval apical organs and the spiralian nervous system
(BioMed Central, 2012-01-24)
Background: Larval features such as the apical organ, apical ciliary tuft, and ciliated bands often complicate the evaluation of hypotheses regarding the origin of the adult bilaterian nervous system. Understanding how ...
Effect of uneven sampling along an environmental gradient on transfer-function performance
(Springer, 2011-04-27)
We investigate the effect that uneven
sampling of the environmental gradient has on
transfer-function performance using simulated community
data. We find that cross-validated estimates of
the root mean squared error ...
Gene expression in bryozoan larvae suggest a fundamental importance of pre-patterned blastemic cells in the bryozoan life-cycle
(BioMed Central, 2011-06-06)
Background: Bryozoa is a clade of aquatic protostomes. The bryozoan life cycle typically comprises a larval stage,
which metamorphoses into a sessile adult that proliferates by asexual budding to form colonies. The homology ...
Ciliary photoreceptors in the cerebral eyes of a protostome larva
(BioMed Central, 2011-03-01)
Background: Eyes in bilaterian metazoans have been described as being composed of either ciliary or
rhabdomeric photoreceptors. Phylogenetic distribution, as well as distinct morphologies and characteristic
deployment ...
Morphogenesis underlying the development of the everted teleost telencephalon
(BioMed Central, 2012-09-18)
Background: Although the mechanisms underlying brain patterning and regionalization are very much conserved, the morphology of different brain regions is extraordinarily variable across vertebrate phylogeny. This is ...
Prediction of CpG-island function: CpG clustering vs. sliding-window methods
(BioMed Central, 2010-05-26)
Background
Unmethylated stretches of CpG dinucleotides (CpG islands) are an outstanding property of mammal genomes. Conventionally, these regions are detected by sliding window approaches using %G + C, CpG observed/expected ...
How malaria models relate temperature to malaria transmission
(BioMed Central, 2013-01-18)
Background: It is well known that temperature has a major influence on the transmission of malaria parasites to their
hosts. However, mathematical models do not always agree about the way in which temperature affects ...
