Mounting evidence suggests an important role for CCAAT-enhancer binding protein delta (C/EBPδ) in the acute-phase response after bacterial infection. However, whether C/EBPδ limits pneumonia remains elusive and is the aim of this study. Therefore, bacterial outgrowth, inflammatory responses, inflammatory cell influx, and survival were assessed in wild-type and C/EBPδ(-/-) mice ...

Geographic parthenogenesis is a distribution pattern, in which parthenogenetic populations tend to live in marginal habitats, at higher latitudes and altitudes and island-like habitats compared with the sexual forms. The facultatively parthenogenetic ant Platythyrea punctata is thought to exhibit this general pattern throughout its wide range in Central America and ...

The non-visual ocular photoreceptor melanopsin, found in the neurons of vertebrate inner retina, absorbs blue light and triggers the 'biological clock' of mammals by activating the suprachiasmatic nuclei (a small region of the brain that regulates the circadian rhythms of neuronal and hormonal activities over 24-hour cycles). The structure of ...

While chemists have extensively studied the photophysical properties of d(6), d(8), and d(10) transition metal complexes, their early transition metal counterparts have received less attention. Quadruply bonded complexes of molybdenum and tungsten supported by carboxylate ligands have intense metal-to-ligand charge transfer (MLCT) absorptions that arise from the electronic coupling of ...

Semi-transparent porous silicon substrates have been developed for pairing nanostructure-initiator mass spectrometry (NIMS) imaging with traditional optical-based microscopy techniques. Substrates were optimized to generate the largest NIMS signal while maintaining sufficient transparency to allow visible light to pass through for optical microscopy. Using these substrates, both phase-contrast and NIMS images ...

Chronic HIV infection induces significant changes in the trafficking of circulating endothelial progenitor cells (EPCs). Specifically, it causes marked depletion of proangiogenic hematopoietic cells , the so called colony-forming unit-endothelial cells (CFU-ECs). In this study we evaluated CFU-ECs in two subjects with acute HIV infection. We found that both patients ...

SUMMARY AT A GLANCE: This cross-sectional study investigated diet, inflammation, lung function and asthma symptoms in Australians asthmatics and healthy controls. Participants with severe persistent asthma showed a different dietary intake pattern compared with healthy controls, which was associated with lower lung function and increased airway inflammation. Asthmatics also had ...

Increased ionic concentrations are associated with the impairment of benthic invertebrate assemblages. However, the causal nature of that relationship must be demonstrated so that it can be used to derive a benchmark for conductivity. The available evidence is organized in terms of six characteristics of causation: co-occurrence, preceding causation, interaction, ...
