Abstract
BACKGROUND The outcome of cholangiopathy developing in intensive care unit (ICU) is not known in patients surviving their ICU stay. AIM To perform a survey in liver units, in order to clarify the course of cholangiopathy after surviving ICU stay. METHODS The files of the liver units affiliated to the French network for vascular liver disease were screened for cases of ICU cholangiopathy developing in patients with normal liver function tests on ICU admission, and no prior history of liver disease. RESULTS Between 2005 and 2015, 16 cases were retrieved. Extensive burns were the cause for admission to ICU in 11 patients. Serum alkaline phosphatase levels increased from day 11 (2-46) to a peak of 15 (4-32) × ULN on day 81 (12-511). Magnetic resonance cholangiography showed irregularities or frank stenosis of the intrahepatic ducts, and proximal extrahepatic ducts contrasting with a normal aspect of the distal common bile duct. Follow-up duration was 20.6 (4.7-71.8) months. Three patients were lost to follow-up; 2 patients died from liver failure and no patient was transplanted. One patient had worsening strictures of the intrahepatic bile ducts with jaundice. Nine patients had persistent but minor strictures of the intrahepatic bile ducts on MR cholangiography, and persistent cholestasis without jaundice. One patient had normal liver function tests. CONCLUSIONS In patients surviving their ICU stay, ICU cholangiopathy is not uniformly fatal in the short term or clinically symptomatic in the medium term. Preservation of the distal common bile duct appears to be a finding differentiating ICU cholangiopathy from other diffuse cholangiopathies.

Abstract
OBJECTIVES Anticitrullinated protein antibodies (ACPA) are specifically associated with rheumatoid arthritis (RA) and produced in inflamed synovial membranes where citrullinated fibrin, their antigenic target, is abundant. We showed that immune complexes containing IgG ACPA (ACPA-IC) induce FcγR-mediated tumour necrosis factor (TNF)-α secretion in macrophages. Since IgM rheumatoid factor (RF), an autoantibody directed to the Fc fragment of IgG, is also produced and concentrated in the rheumatoid synovial tissue, we evaluated its influence on macrophage stimulation by ACPA-IC. METHODS With monocyte-derived macrophages from more than 40 healthy individuals and different human IgM cryoglobulins with RF activity, using a previously developed human in vitro model, we evaluated the effect of the incorporation of IgM RF into ACPA-IC. RESULTS IgM RF induced an important amplification of the TNF-α secretion. This effect was not observed in monocytes and depended on an increase in the number of IgG-engaged FcγR. It extended to the secretion of interleukin (IL)-1β and IL-6, was paralleled by IL-8 secretion and was not associated with overwhelming secretion of IL-10 or IL-1Ra. Moreover, the RF-induced increased proinflammatory bioactivity of the cytokine response to ACPA-IC was confirmed by an enhanced, not entirely TNF-dependent, capacity of the secreted cytokine cocktail to prompt IL-6 secretion by RA synoviocytes. CONCLUSIONS By showing that it can greatly enhance the proinflammatory cytokine response induced in macrophages by the RA-specific ACPA-IC, these results highlight a previously undescribed, FcγR-dependent strong proinflammatory potential of IgM RF. They clarify the pathophysiological link between the presence of ACPA and IgM RF, and RA severity.

Abstract
In mental diseases, the brain does not systematically adjust motor activity to feeding. Probably, the most outlined example is the association between hyperactivity and anorexia in Anorexia nervosa. The neural underpinnings of this 'paradox', however, are poorly elucidated. Although anorexia and hyperactivity prevail over self-preservation, both symptoms rarely exist independently, suggesting commonalities in neural pathways, most likely in the reward system. We previously discovered an addictive molecular facet of anorexia, involving production, in the nucleus accumbens (NAc), of the same transcripts stimulated in response to cocaine and amphetamine (CART) upon stimulation of the 5-HT(4) receptors (5-HTR(4)) or MDMA (ecstasy). Here, we tested whether this pathway predisposes not only to anorexia but also to hyperactivity. Following food restriction, mice are expected to overeat. However, selecting hyperactive and addiction-related animal models, we observed that mice lacking 5-HTR(1B) self-imposed food restriction after deprivation and still displayed anorexia and hyperactivity after ecstasy. Decryption of the mechanisms showed a gain-of-function of 5-HTR(4) in the absence of 5-HTR(1B), associated with CART surplus in the NAc and not in other brain areas. NAc-5-HTR(4) overexpression upregulated NAc-CART, provoked anorexia and hyperactivity. NAc-5-HTR(4) knockdown or blockade reduced ecstasy-induced hyperactivity. Finally, NAc-CART knockdown suppressed hyperactivity upon stimulation of the NAc-5-HTR(4). Additionally, inactivating NAc-5-HTR(4) suppressed ecstasy's preference, strengthening the rewarding facet of anorexia. In conclusion, the NAc-5-HTR(4)/CART pathway establishes a 'tight-junction' between anorexia and hyperactivity, suggesting the existence of a primary functional unit susceptible to limit overeating associated with resting following homeostasis rules.

Abstract
OBJECTIVE To analyse Fcγ receptor (FcγR) expression on monocytes and macrophages from rheumatoid arthritis (RA) patients versus healthy controls (HC), and to compare their responses to immune complexes containing RA-specific anti-citrullinated proteins auto antibodies (ACPA). METHODS Monocytes and monocyte-derived macrophages were obtained from the peripheral blood of 34 RA patients and 69 HC. FcγR expression was studied by flow cytometry. Cells were stimulated with ACPA-containing immune complexes, and tumour necrosis factor alpha (TNFα) was assayed in culture supernatants. RESULTS Variations distinguished RA from HC monocytes, corresponding to a 5% and 6% decrease in the percentages of monocytes expressing FcγRI and FcγRII, respectively, and a 7% increase in the proportion of FcγRIII-positive monocytes. Although in both HC and RA patients macrophage differentiation was accompanied by a dramatic increase in the percentage of FcγRIII-expressing cells (72% vs 74.5%), the parallel decline in the proportion of FcγRI-positive cells was markedly smaller in RA (7% vs 43%). Monocytes and macrophages from patients were responsive to ACPA-containing immune complexes but TNFα production in both cell types neither differed from that observed with the corresponding cells from HC, nor correlated with FcγR expression or clinical or biological data. In RA as in HC, ACPA-containing immune complexes induced secretions of more TNFα in macrophages than in paired monocytes (ninefold). Finally, the proinflammatory potential of ACPA-containing immune complexes was confirmed in CD14-positive monocyte macrophages from the synovial fluid of four RA patients. CONCLUSIONS ACPA-containing immune complexes induce TNFα secretion by blood and synovial fluid-derived macrophages from RA patients, fitting with their probable involvement in RA pathophysiology.

Abstract
The microdisplacements generated by a small localized overload at the free surface are visualized experimentally inside a packing of steel beads. For a triangular packing, beads rearrangements remain confined in two inverted triangles on both sides of the applied overload. This pattern disappears for stronger disorder. A simple model allows us to account for these observations and to relate them to the stress function response measured via photoelastic visualizations. This provides a different tool to probe the mechanical Green's function in weakly confined packings of rigid grains the description of which is the most challenged.

Abstract
Hereditary neuropathy liability to pressure palsies is characterized by recurring accesses of painless paralysis at the level of various nerves likely to be compressed. This affection remains underdiagnosed because of its usually benign course, sometimes without any symptom. The diagnosis is supported by clinical and electrophysiological data associated with, in the majority of patients, a deletion of one of the alleles coding for protein PMP 22 on the level of the locus 17p11.2.

Abstract
We investigate steady granular surface flows in a rotating drum and demonstrate the existence of rigid clusters of grains embedded in the flowing layer. These clusters appear to be fractal and their size is power law distributed from the grain size scale up to the thickness of the flowing layer. The implications of the absence of a characteristic length scale on available theoretical models of dense granular flows are discussed. Finally, we suggest a possible explanation of the difference between velocity profiles observed in surface flows and in flows down a rough inclined plane.

Abstract
Human cytomegalovirus (CMV) infection of bone marrow transplant recipients can cause pancytopenia, as well as life-threatening interstitial pneumonia. CMV replicates actively in bone marrow stromal cells, whereas it remains latent in hematopoietic progenitors. Our aim was to study the influence of CMV infection on adherence of CD34(+) cells to the myofibroblastic component of human bone marrow and examine transmission of virus from myofibroblasts to CD34(+) cells. We show that smooth actin, but not fibronectin, organization is markedly modified by CMV infection of bone marrow stromal myofibroblasts. Nonetheless, CMV infection led to increased adherence of the CD34(+) progenitor cell line, KG1a, relative to adherence to uninfected myofibroblasts from the same donors. Adherence of CD34(+) cells to infected bone marrow myofibroblasts resulted in transfer of virions and viral proteins through close cell-to-cell contacts. This phenomenon may play a role in the pathophysiology of CMV bone marrow infection and in eventual virus dissemination.

Abstract
The human cytomegalovirus (HCMV) US28 gene product, pUS28, is a G protein-coupled receptor that interacts with both CC and CX(3)C chemokines. To date, the role of pUS28 in immune evasion and cell migration has been studied only in cell types that can establish productive HCMV infection. We show that HCMV can latently infect THP-1 monocytes and that during latency US28 is transcribed. We also show that the transcription is sustained during differentiation of the THP-1 monocytes. Since cells expressing pUS28 were previously shown to adhere to immobilized CX(3)C chemokines (C. A. Haskell, M. D. Cleary, and I. F. Charo, J. Biol. Chem. 275:34183-34189, 2000), we hypothesize that latently infected circulating monocytes express pUS28, thereby enabling adhesion of these cells to CX(3)C-exposing endothelium. Consequently, the US28-encoded chemokine receptor may play an important role in dissemination of latent HCMV.

Abstract
In permissive cells, human cytomegalovirus encodes the protein US28, a functional CC chemokine receptor. US28 polyadenylated mRNA could be detected by RT-PCR as early as 2 h post-infection. US28 mRNA appeared after major IE1 transcripts (UL123), but before transcripts of the early genes pp65 (UL83) and gB (UL55), and the late gene pp150 (UL32). This temporal appearance indicates that US28 is transcribed earlier than previously reported. Furthermore, US28 mRNA could be detected in semi- and non-permissive cells.

Abstract
An in vitro model of human CMV infection of primary retinal pigment epithelial (RPE) cells was used to study the effects of cytokines on CMV replication in these cells, which are targets of CMV infection in vivo. IFN-gamma and IFN-beta were potent inhibitors of CMV replication in RPE cells, while TNF-alpha, IL-1beta, or TGF-beta2 did not affect viral replication. Inhibition by IFN-gamma, and to a lesser extent IFN-beta, was almost completely reversed by addition of L-tryptophan to the culture medium, strongly implicating the indoleamine 2,3 dioxygenase (IDO) pathway. Polyadenylated IDO mRNA accumulation was detected as early as 2 h after IFN stimulation. Furthermore, CMV blocked the production of nitric oxide by the inducible form of nitric oxide synthase. This inhibition depended on a functional viral genome. However, exogenous nitric oxide significantly inhibited viral protein expression in RPE cells. Thus, CMV infection blocks the inducible nitric oxide synthase pathway activated by IFN-gamma and IL-1beta, but cannot counteract the IFN-induced IDO pathway, which ultimately controls its replication in primary human RPE cells.

Abstract
Based on an extensive sampling regime from both nesting populations and bycatch, frequency analyses of mitochondrial (mt) DNA control region haplotypes in the Mediterranean were used to assess the genetic structure and stock composition of the loggerhead sea turtle, Caretta caretta, in different marine fisheries. The analyses show the following. (i) In drifting longline fisheries working in Mediterranean pelagic habitats 53-55% of turtles caught originated from the Mediterranean stock; (ii) In bottom-trawl fisheries all turtle bycatch is derived from this regional stock; (iii) This regional stock contribution to fishery bycatch suggests that the population size of the Mediterranean loggerhead nesting population is significantly larger than previously thought. This is consistent with a recent holistic estimate based on the discovery of a large rookery in Libya. (iv) Present impact of fishery-related mortality on the Mediterranean nesting population is probably incompatible with its long-term conservation. Sea turtle conservation regulations are urgently needed for the Mediterranean fisheries. (v) The significant divergence of mtDNA haplotype frequencies of the Turkish loggerhead colonies define this nesting population as a particularly important management unit. Large immature and adult stages from this management unit seem to be harvested predominantly by Egyptian fisheries. (vi) Combined with other data, our findings suggest that all the nesting populations in the Mediterranean should be considered as management units sharing immature pelagic habitats throughout the Mediterranean (and possibly the eastern Atlantic), with distinct and more localized benthic feeding habitats in the eastern basin used by large immatures and adults. (vii) Between the strict oceanic pelagic and the benthic stages, immature turtles appear to live through an intermediate neritic stage, in which they switch between pelagic and benthic foods.

Abstract
Human cytomegalovirus (HCMV), a betaherpesvirus, has developed several ways to evade the immune system, notably downregulation of cell surface expression of major histocompatibility complex class I heavy chains. Here we report that HCMV has devised another means to compromise immune surveillance mechanisms. Extracellular accumulation of both constitutively produced monocyte chemoattractant protein (MCP)-1 and tumor necrosis factor-superinduced RANTES (regulated on activation, normal T cell expressed and secreted) was downregulated in HCMV-infected fibroblasts in the absence of transcriptional repression or the expression of polyadenylated RNA for the cellular chemokine receptors CCR-1, CCR-3, and CCR-5. Competitive binding experiments demonstrated that HCMV-infected cells bind RANTES, MCP-1, macrophage inflammatory protein (MIP)-1beta, and MCP-3, but not MCP-2, to the same receptor as does MIP-1alpha, which is not expressed in uninfected cells. HCMV encodes three proteins with homology to CC chemokine receptors: US27, US28, and UL33. Cells infected with HCMV mutants deleted of US28, or both US27 and US28 genes, failed to downregulate extracellular accumulation of either RANTES or MCP-1. In contrast, cells infected with a mutant deleted of US27 continues to bind and downregulate those chemokines. Depletion of chemokines from the culture medium was at least partially due to continuous internalization of extracellular chemokine, since exogenously added, biotinylated RANTES accumulated in HCMV-infected cells. Thus, HCMV can modify the chemokine environment of infected cells through intense sequestering of CC chemokines, mediated principally by expression of the US28-encoded chemokine receptor.

Abstract
Chemokines play a major role in inflammatory responses and affect hematopoiesis both negatively and positively. We show that fresh isolates and laboratory strains (Towne and Ad-169) of human cytomegalovirus (HCMV) induce production of the CC chemokine RANTES in fibroblasts. Induction of extracellular RANTES production occurred as early as 8 h after infection, peaked around 24 h after infection, and was almost undetectable by 48 and 72 h. Upregulation occurred in the absence of viral DNA synthesis, suggesting that it was due to immediate-early-early HCMV gene expression. CMV infection stimulated RANTES transcription, since reverse transcription-PCR detected a sharp increase in RANTES RNA which persisted even when extracellular RANTES was no longer detected. Induction of RANTES in fibroblasts was not due to prior induction of tumor necrosis factor alpha or interleukin 1 beta. Down-regulation required an active viral genome. Decrease of RANTES in culture supernatants may be associated with the appearance of the HCMV CC chemokine receptor US28, since we show that this gene is transcribed as early as 8 h after infection. Modulation of CC chemokine production early during CMV infection might have a regulatory effect on viral replication, as well as affect immune surveillance.

Abstract
The loggerhead turtle Caretta caretta is an endangered species in the Mediterranean. Therefore, the definition of the Mediterranean population, and their relationships to the Atlantic population is of fundamental importance. For this purpose, we have sequenced a portion of the mitochondrial cytochrome b gene to generate genetic markers. Results indicate that the Mediterranean nesting female population is genetically isolated from the Atlantic nesting female population, but loggerhead turtles of Atlantic origin were found in the West Mediterranean basin. This entry of Atlantic loggerheads in the Mediterranean confirms earlier speculations and presents special conservation problems. The Spanish swordfish longline fishery which incidentally captures large numbers of loggerheads in the West Mediterranean basin has therefore an impact on the Atlantic population. These data demonstrate the international nature of marine turtle conservation.

Abstract
A radioreceptor assay (RRA) was developed using rabbit platelet membrane preparations to quantify platelet-activating factor (PAF) and lyso-PAF, the deacylated derivative of PAF, in a variety of tissues and biological fluids. We examined PAF and lyso-PAF levels in different rat brain areas with regard to the many proven and postulated actions of PAF in brain functions. Human saliva was selected to check the validity of this RRA. The samples were extracted with methanol/chloroform/water and purified by high-performance liquid chromatography on a 5-microns Nucleosil Si column (overall recovery: 78%). Sample extracts were acetylated before chromatography to assay lyso-PAF. PAF itself was assayed in non-aceylated samples. A competitive binding assay was performed using aliquots of platelet membrane preparation and tritiated PAF. The minimum detectable amount of PAF was 144 pg per tube and the receptor was highly specific for PAF. In human saliva, we confirm the presence of PAF and lyso-PAF within the range expected. Moreover there was a good correlation between the RRA and the aggregation assay (r = 0.976). A defined cocktail of protease inhibitors allowed storage of platelet membrane preparations for at least 3 months at -20 degrees C with no change in binding properties. In the brain we observed the prevalent presence of lyso-PAF and large variations in PAF and lyso-PAF concentrations between the different brain areas analyzed. PAF was undetectable in the hypothalamus but the lyso-PAF concentration was 2.5 micrograms/g wet tissue. The PAF concentration in the cortex varied from 0 to 16 ng/g wet tissue while that of lyso-PAF was 0.7 micrograms/g wet tissue. Moreover the amount of lyso-PAF varied between the different brain areas analyzed. The hippocampus contained the highest amount (7 micrograms/g wet tissue), and relatively high levels were found in the hypothalamus, medulla oblongata and corpus striatum. The cerebellum and cortex contained the lowest levels of lyso-PAF. These findings show that PAF is present in the central nervous system mainly in its inactive form, lyso-PAF, and suggest that its effects as a modulator of brain function may be dependent on deacetylation, rather than synthesis.

Abstract
Complexes of plasma membrane segments with desmosomes and attached tonofilaments were separated from the stratum spinosum cells of calf muzzle by means of moderately alkaline buffers of low ionic strength and mechanical homogenization. These structures were further fractionated by the use of various treatments including sonication, sucrose gradient centrifugation, and extraction with buffers containing high concentrations of salt, urea, citric acid, or detergents. Subfractions enriched in desmosome-tonofilament-complexes and tonofilament fragments were studied in detail. The desmosome structures such as the midline, the trilaminar membrane profile, and the desmosomal plaque appeared well preserved and were notably resistant to the various treatments employed. Fractions containing desmosome-tonofilament complexes were invariably dominated by the nonmembranous proteins of the tonofilaments which appeared as five major polypeptide bands (apparent molecular weights: 48,000; 51,000; 58,000; 60,000; 68,000) present in molar ratios of approx. 2:1:1:2:2. Four of these polypeptide bands showed electrophoretic mobilities similar to those of prekeratin polypeptides from bovine hoof. However, the largest polypeptide (68,000 mol wt) migrated significantly less in polyacrylamide gels than the largest component of the hoof prekeratin (approximately 63,000 mol wt). In addition, a series of minor bands, including carbohydrate-containing proteins, were identified and concluded to represent constituents of the desmosomal membrane. The analysis of protein-bound carbohydrates (total 270 microgram/mg phospholipid in desmosome-enriched subfractions) showed the presence of relatively high amounts of glucosamine, mannose, galactose, and sialic acids. These data as well as the lipid composition (e.g., high ratio of cholesterol to phospholipids, relatively high contents of sphingomyelin and gangliosides, and fatty acid pattern) indicate that the desmosomal membrane is complex in protein and lipid composition and has a typical plasma membrane character. The similarity of the desmosome-associated tonofilaments to prekeratin filaments and other forms of intermediate-sized filaments is discussed.
