Lesion-induced microglial/macrophage responses were investigated in post-mortem human spinal cord tissue of 20 patients who had died at a range of survival times after spinal trauma or brain infarction. Caudal to the spinal cord injury or brain infarction, a strong increase in the number of activated microglial cells was observed within the denervated intermediate grey matter and ventral horn of patients who died shortly after the insult (4-14 days). These cells were positive for the leucocyte common antigen (LCA) and for the major histocompatibility complex class II antigen (MHC II), with only a small proportion staining for the CD68 antigen. After longer survival times (1-4 months), MHC II-immunoreactivity (MHC II-IR) was clearly reduced in the grey matter but abundant in the white matter, specifically within the degenerating corticospinal tract, co-localising with CD68. In this fibre tract, elevated MHC II-IR and CD68-IR were still detectable 1 year after trauma or stroke. It is likely that the subsequent expression of CD68 on MHC II-positive microglia reflects the conversion to a macrophage phenotype, when cells are phagocytosing degenerating presynaptic terminals in grey matter target regions at early survival times and removing axonal and myelin debris in descending tracts at later survival times. No T or B cell invasion or involvement of co-stimulatory B7 molecules (CD80 and CD86) was observed. It is possible that the up-regulation of MHC II on microglia that lack the expression of B7 molecules may be responsible for the prevention of a T cell response, thus protecting the spinal cord from secondary tissue damage.

Koi herpesvirus (KHV), recently designated in the species Cyprinid Herpesvirus 3, is the causative agent of a lethal disease in koi and common carp. In the present study, we investigated the portal of entry of KHV in carp using bioluminescence imaging. Taking profit of the recent cloning of the KHV genome as a bacterial artificial chromosome (BAC), we produced a recombinant plasmid encoding a firefly luciferase (LUC) expression cassette inserted in the intergenic region between ORF 136 and ORF 137. Two viral strains were then reconstituted from the modified plasmid: the FL BAC 136 LUC excised strain and the FL BAC 136 LUC TK revertant strain encoding a disrupted and a wild-type thymidine kinase (TK) locus, respectively. In vitro, the two recombinant strains replicated comparably to the parental FL strain. The FL BAC 136 LUC TK revertant strain was shown in vitro to induce a bioluminescent signal allowing the detection of single positive cells as early as 24 hours post-infection; while in vivo, it induced KHV infection in carp that was indistinguishable from that induced by the parental FL strain. To identify the KHV portal of entry, carp were analyzed by bioluminescence imaging at different time post-infection with the FL BAC 136 LUC TK revertant strain. These analyses demonstrated that the skin of the fish, covering the fins and also the body, is the major portal of entry of KHV in carp. Finally, to further demonstrate the role of the skin as the KHV portal of entry, we constructed an original system nicknamed "U-tube" to perform per-cutaneous infection restricted to the posterior part of the fish. All the data obtained in the present study demonstrate that the skin and not the gills is the major portal of entry of KHV in carp. [less ▲]

Cadmium (Cd) tolerance seems to be a constitutive species-level trait in Arabidopsis halleri sp. halleri. Therefore, an interspecific cross was made between A. halleri and its closest nontolerant interfertile relative, Arabidopsis lyrata sp. petraea, and a first-generation backcross population (BC1) was used to map quantitative trait loci (QTL) for Cd tolerance. Three QTL were identified, which explained 43%, 24%, and 16% of the phenotypic variation in the mapping population. Heavy metal transporting ATPases4 (HMA4), encoding a predicted heavy metal ATPase, colocalized with the peak of the major QTL Cdtol-1 and was consequently further studied. HMA4 transcripts levels were higher in the roots and the shoots of A. halleri than in A. lyrata sp. petraea. Furthermore, HMA4 was also more highly expressed in all BC1 genotypes harboring the HMA4 A. halleri allele at the QTL Cdtol-1, independently of the presence of an A. halleri allele at the two other QTL. Overexpression of AhHMA4 in yeast (Saccharomyces cerevisiae) supported a role of HMA4 in zinc (Zn) and Cd transport by reducing the Cd and Zn contents of the yeast cells. In epidermal tobacco (Nicotiana tabacum) cells, AhHMA4:green fluorescent protein was clearly localized in the plasma membrane. Taken together, all available data point to the elevated expression of HMA4P(1B)-type ATPase as an efficient mechanism for improving Cd/ Zn tolerance in plants under conditions of Cd/ Zn excess by maintaining low cellular Cd2+ and Zn2+ concentrations in the cytoplasm.

The characterization of exozodiacal light emission is both important for the understanding of planetary systems evolution and for the preparation of future space missions aiming to characterize low mass planets in the habitable zone of nearby main sequence stars. The Large Binocular Telescope Interferometer (LBTI) exozodi survey aims at providing a ten-fold improvement over current state of the art, measuring dust emission levels down to a typical accuracy of 12 zodis per star, for a representative ensemble of 30+ high priority targets. Such measurements promise to yield a final accuracy of about 2 zodis on the median exozodi level of the targets sample. Reaching a 1 σ measurement uncertainty of 12 zodis per star corresponds to measuring interferometric cancellation ("null") levels, i.e visibilities at the few 100 ppm uncertainty level. We discuss here the challenges posed by making such high accuracy mid-infrared visibility measurements from the ground and present the methodology we developed for achieving current best levels of 500 ppm or so. We also discuss current limitations and plans for enhanced exozodi observations over the next few years at LBTI. [less ▲]

Orienting healthcare towards people-centred primary care is one of the four policy directions for the renewal of primary healthcare outlined in the World Health Report 2008, Primary Health Care: Now More than Ever - along with universal coverage, health in all policies and more inclusive health governance. During the Fourth Geneva Conference on Person- centred Medicine, WHO organized a session on policies and health system interventions that help make care more people- centred. Case studies from Chile, New Zealand, Spain (Basque Region) and Uganda illustrated that the implementation of people-centred care (PCC) varies greatly across countries. Despite these variations, three key lessons emerge. First - efforts to make care more people-centred may more likely succeed when they are linked to or are part of other major drivers of change such as improving equity in health, establishing rights or addressing chronic diseases. Second - such efforts tend to be long-term processes that require sustained political will and leadership as well as consistency over time. Top-down, supply-driven reforms need to be complemented with bottom-up, demand-driven measures to facilitate change. Third - participation of all interested parties (policy-makers, providers and users) as well as other sectors is vital for ensuring success. The case studies suggest that people-centred care is more likely to succeed when it is implemented using system- wide approaches that make use of multiple policy instruments intervening at different levels while guaranteeing sustainable financing and alignment of financial incentives.
