Plants as reef fish: fitting the functional form of seedling recruitment.
(Am Nat, 2007-08)
The life histories of many species depend first on dispersal to local sites and then on establishment. After dispersal, density-independent and density-dependent mortalities modify propagule supply, determining the number ...
HLA-B-associated transcript 3 (Bat3)/Scythe is essential for p300-mediated acetylation of p53.
(Genes Dev, 2007-04-01)
In response to DNA damage, p53 undergoes post-translational modifications (including acetylation) that are critical for its transcriptional activity. However, the mechanism by which p53 acetylation is regulated is still ...
Multiple, conserved cryptic recombination signals in VH gene segments: detection of cleavage products only in pro B cells.
(J Exp Med, 2007-12-24)
Receptor editing is believed to play the major role in purging newly formed B cell compartments of autoreactivity by the induction of secondary V(D)J rearrangements. In the process of immunoglobulin heavy (H) chain editing, ...
Working at the interface of phylogenetics and population genetics: a biogeographical analysis of Triaenops spp. (Chiroptera: Hipposideridae).
(Mol Ecol, 2007-02)
New applications of genetic data to questions of historical biogeography have revolutionized our understanding of how organisms have come to occupy their present distributions. Phylogenetic methods in combination with divergence ...
Measurement of intracellular strain on deformable substrates with texture correlation.
(J Biomech, 2007)
Mechanical stimuli are important factors that regulate cell proliferation, survival, metabolism and motility in a variety of cell types. The relationship between mechanical deformation of the extracellular matrix ...
The CO/HO system reverses inhibition of mitochondrial biogenesis and prevents murine doxorubicin cardiomyopathy.
(J Clin Invest, 2007-12)
The clinical utility of anthracycline anticancer agents, especially doxorubicin, is limited by a progressive toxic cardiomyopathy linked to mitochondrial damage and cardiomyocyte apoptosis. Here we demonstrate that ...
The feeling of looking.
(Nat Neurosci, 2007-05)
Gene expression signatures that predict radiation exposure in mice and humans.
(PLoS Med, 2007-04)
BACKGROUND: The capacity to assess environmental inputs to biological phenotypes is limited by methods that can accurately and quantitatively measure these contributions. One such example can be seen in the context of exposure ...
Shared features in the pathobiology of babesiosis and malaria.
(Trends Parasitol, 2007-12)
The pathobiology of malaria has been extensively studied in humans but many questions remain, especially regarding fulminant disease associated with Plasmodium falciparum infection. Babesiosis, recognized since biblical ...
Role of the midbrain dopaminergic system in modulation of vocal brain activation by social context.
(Eur J Neurosci, 2007-06)
In a well-studied model of social behaviour, male zebra finches sing directed song to court females and undirected song, used possibly for practice or advertisement. Although the two song types are similar, the level of ...
