Differences in Kaposi sarcoma-associated herpesvirus-specific and herpesvirus-non-specific immune responses in classic Kaposi sarcoma cases and match…
2011
Kaposi sarcoma (KS) might develop because of incompetent immune responses, both non-specifically and specifically against the KS-associated herpesvirus (KSHV). Peripheral blood mononuclear cells from 15 classic (non-AIDS) KS cases, 13 KSHV seropositives (without KS) and 15 KSHV-seronegative controls were tested for interferon-γ T-cell (enzyme-linked immunospot [Elispot]) responses to KSHV-latency-associated nuclear antigen (LANA), KSHV-K8.1 and CMV/Epstein-Barr virus (EBV) peptide pools. The forearm and thigh of each participant was also tested for delayed-type hypersensitivity (DTH) against common recall antigens. Groups were compared with Fisher exact test and multinomial logistic regress…
Patterns of algal recovery and small-scale effects of canopy removal as a result of human trampling on a Mediterranean rocky shallow community.
2004
The ecological importance of marine algae is widely known but in shallow coastal areas the composition and structure of algal communities may be affected by different human activities. Recovery from different trampling disturbances of two competing morphological groups (i.e. macroalgae and algal turfs) and effects of macroalgal canopy removal on the dominant associated fauna were examined using controlled trampling experiments. Six months after trampling disturbance was removed, the two morphological groups closely resembled control (untrampled) conditions, both in terms of cover and canopy (%). In particular, macroalgal recovery seemed to be very rapid: the higher the impact on the system …
Carbapenem-Susceptible OXA-23-Producing Proteus mirabilis in the French Community
2019
International audience; Nineteen Proteus mirabilis isolates producing the carbapenemase OXA-23 were recovered over a 2-year period in 19 French hospitalized patients, of whom 12 had community onset infections. The isolates exhibited a slightly reduced susceptibility to carbapenems. Whole-genome analysis revealed that all 19 isolates formed a cluster compared to 149 other P. mirabilis isolates. Because of its susceptibility to carbapenems, this clone may be misidentified as a penicillinase producer while it constitutes a reservoir of the OXA-23-encoding gene in the community.
Immune Control in Hepatocellular Carcinoma Development and Progression: Role of Stromal Cells
2014
Immune control of hepatocellular carcinoma (HCC) is executed by effector immune cells, which efficiently eliminate malignant transformed cells. However, progression of HCC clearly documents failure of tumor immune control, which led to the concept of immune subversion by the tumor environment. Particularly tumor-associated stromal cells cooperate within an inflammatory network, which is responsible for immune privilege. The stromal cell composition matures during tumor growth and is derived from surrounding noncancerous tissue or from circulating cells recruited to the tumor site. Therefore, immunosuppressive stromal cells represent heterogeneous cell lineages, including myeloid cells, lymp…
Sex differences in early carotid atherosclerosis (from the community-based Gutenberg-Heart Study).
2010
The objectives of this study were to describe gender differences in intima-media thickness (IMT) in a community-based population study and to define normal IMT values for healthy men and women. In total, 4,814 participants (aged 35 to 74 years; 2,433 men, 2,381 women) from the Gutenberg-Heart Study (GHS) were included. IMT was measured at both common carotid arteries using an edge detection system. Median IMT was 0.62 mm (25th percentile 0.55, 75th percentile 0.70) in women and 0.65 mm (25th percentile 0.57, 75th percentile 0.75) in men and was significantly associated with age (p0.0001). On multivariate analysis, advanced age, smoking, and arterial hypertension were positively associated w…
The CO-releasing molecule CORM-3 protects against articular degradation in the K/BxN serum transfer arthritis model.
2010
Contains fulltext : 89015.pdf (Publisher’s version ) (Closed access) Carbon monoxide-releasing molecules can counteract inflammatory responses. The aim of this study was to investigate whether tricarbonylchloro(glycinate)ruthenium (II) (CORM-3) is able to control the effector phase of experimental arthritis. Arthritis was induced in C57Black-6 mice by an intraperitoneal injection of serum from arthritic K/BxN mice. CORM-3 was administered intraperitoneally at 10 mg/kg/day (5 mg/kg twice a day) from days 0 to 10 and animals were sacrificed on day 11. Serum levels of osteocalcin and prostanoids were measured by enzyme-linked immunosorbent assay and radioimmunoassay. Gene expression was determ…
Particularismes i populismes als països de llengua catalana
2020
[cat] L'article analitza breument l'ampla varietat de conceptes de populisme en la política actual. Aquesta anàlisi intenta mostrar com el populisme ha donat suport als particularismes lingüístics a València i a Mallorca. Aquests particularismes (anomenats blaverisme a València, i gonellisme a Mallorca) no reconeixen la unitat de la comunitat lingüística catalana, i per tant amenacen la recuperació social (normalització) de la llengua catalana.
Oriental/ Occidental Catalan and Valencian: More Again
2018
En un recent treball (2015) Joan Veny ha presentat «una revisió de les teories emeses a propòsit de l’origen de la partió del domini lingüístic en català occidental i català oriental». El present treball formula puntuals objeccions a la revisió realisada per est autor, matisant alguna datació oferida i reconsiderant el paper que el substrat pogué eixercir en la possiblement naixent dicefàlia del català. In a recent paper (2015), Joan Veny has presented «a review of the theories concerning the origin of the division in Western Catalan and Eastern Catalan for this linguistic domain». This paper formulates some punctual objections to Veny’s review, including some nuanced dates and the revisite…
Study of the role of the CDC48 chaperone protein in plant immunity
2018
The chaperone protein CDC48 (Cell division cycle 48) is a major regulator of the quality control of proteins and is involved in various cellular processes in animals and yeast. In contrast, the role of CDC48 in plants is poorly known. In the present work, we investigated the function of CDC48 in plant immunity thanks to the cryptogein/tobacco biological model, cryptogein being produced by the oomycete phytophthora cryptogea.Three strategies were carried out. First, the dynamic of accumulation CDC48 together with intracellular events inherent to the immune response were analyzed in both wild-type and CDC48 overexpressing tobacco cells (CDC48-TAP line). Second, a list if CDC48 partners was es…
