The character of a cell is defined by its constituent proteins, which are the result of specific
patterns of gene expression. Crucial determinants of gene expression patterns are DNA-…

Cells of a multicellular organism are genetically homogeneous but structurally and functionally
heterogeneous owing to the differential expression of genes. Many of these differences in …

A common detection and classification system is needed for epidemiologic studies of age-related
maculopathy (ARM). Such a grading scheme for ARM is described in this paper. ARM …

USNO-B is an all-sky catalog that presents positions, proper motions, magnitudes in various
optical passbands, and star/galaxy estimators for 1,042,618,261 objects derived from …

Vertebrate CpG islands (CGIs) are short interspersed DNA sequences that deviate
significantly from the average genomic pattern by being GC-rich, CpG-rich, and predominantly …

It is likely that most vertebrate genes are associated with ‘HTF islands’—DNA sequences in
which CpG is abundant and non-methylated. Highly tissue-specific genes, though, usually …

). It may also contribute to immobilization of mammalian transposons, suppression of
transcriptional noise, and the control of tissue-specific gene expression, but decisive evidence on …

Geneticists study the gene; however, for epigeneticists, there is no obvious' epigene'.
Nevertheless, during the past year, more than 2,500 articles, numerous scientific meetings and a …

The IBIS telescope is the high angular resolution gamma-ray imager on-board the INTEGRAL
Observatory, successfully launched from Baikonur (Kazakhstan) the 17th of October 2002. …

Methylation of DNA at position five of the cytosine ring occurs at most CpG dinucleotides in
the mammalian genome and is essential for embryonic viability. With several of the key …
