Research on intertidal community structure and recovery in the California Current System has largely focused macrophytes invertebrates occupying two-dimensional, readily studied “open” rock surfaces. However, most rocky shores have a “third” dimension that includes channels, cracks, crevices, overhangs whose organismal assemblages, termed “cryptic communities,” are poorly studied. Cryptic commu...
This review focuses on the evolutionary causes and consequences of limited attention, defined as the restricted rate of information processing by the brain. The available data suggest, first, that limited attention is a major cognitive constraint determining animals' search for cryptic food, and, second, that limited attention reduces animals' ability to detect predators while involved in chall...
We retrospectively evaluate the presence of cryptic fibromuscular dysplasia (FMD) (i.e. not macroscopically visible and not associated to FMD in larger arteries) in the small meningeal vessels in a comprehensive series of patients. Such a study has not been performed before to our knowledge. The meningeal tissue has been systematically examined in a series of 100 consecutive autopsies. The immu...
Mantle cell lymphoma (MCL) is a mature B-cell neoplasm composed of monomorphic small to medium-sized atypical lymphocytes arising from naïve mantle zone B-cells, with a generally aggressive and incurable clinical course. The t(11;14)(q13;q32) between IGH@ and CCND1 is present in almost all cases of MCL. Secondary cytogenetic abnormalities are common, and have been associated in some cases with ...
Phages are the most abundant entity in the biosphere and outnumber bacteria by a factor of 10. Phage DNA may also constitute 20% of bacterial genomes; however, its role is ill defined. Here, we explore the impact of cryptic prophages on cell physiology by precisely deleting all nine prophage elements (166 kbp) using Escherichia coli. We find that cryptic prophages contribute significantly to re...
Recent studies have shown that cryptic unbalanced subtelomeric rearrangements contribute to a significant proportion of idiopathic syndromic mental retardation cases. Using a fluorescent genotyping based strategy, we found a 10% rate of cryptic subtelomeric rearrangements in a large series of 150 probands with severe idiopathic syndromic mental retardation and normal RHG-GTG banded karyotype. F...
This contribution provides a synopsis of the presentations and discussions during the SIG session on cryptic speciation in lichen-forming fungi held during IMC9. In several cases, a re-examination of morphology against the background of molecular phylogenetic evidence revealed, sometimes subtle, morphological and/or chemical characters, supporting the distinction of particular clades at species...
Splice site selection is a key step that determines the mRNA isoforms generated from a single transcript. The large diversity in splice site sequences emphasizes the plasticity of splice site recognition and selection. In this report, a cell-based reporter system using a SMN1/2 cassette exon was applied to study the roles governing the activation of a cryptic 5'SS from the intron 4 of the CT/CG...
