Thrombotic thrombocytopenic purpura (TTP) leading to pseudotumour's autoimmune pancreatitis (AIP): A case report
2012
International audience; Introduction: Autoimmune pancreatitis is an idiopathic inflammatory disease that produces pancreatic masses and ductal strictures. This benign disease can be associated with extrapancreatic manifestations including cholangitis, sialadenitis, inflammatory bowel disease or retroperitoneal fibrosis, mediastinal adenopathy, interstitial nephritis mainly due to immunoglobulin G4 (Ig G4), and occasional association with other auto-immune diseases. Observation: We report a 57-year-old woman who developed thrombotic thrombocytopenic purpura (UP) and pseudo-tumour's seronegative autoimmune pancreatitis (ATP) type 1. The patient was initially treated with pulse corticosteroids…
HLA-B27-restricted CD8 T cells derived from synovial fluids of patients with reactive arthritis and ankylosing spondylitis.
1993
Ankylosing spondylitis and seronegative spondylarthropathies such as Reiter's syndrome and reactive arthritis are strongly associated with HLA-B27. However, the mechanisms by which HLA-B27 is involved in disease susceptibility and pathogenesis are unknown. If the disease association is a consequence of HLA-B27's physiological function in antigen presentation, the disease should be mediated by cytotoxic T lymphocytes (CTLs) that recognise bacterial or self peptides presented by HLA-B27. Proof of this arthritogenic peptide model requires isolation of B27-restricted CD8 T cells from arthritic joints of patients with spondylarthropathies. An important question is whether "arthritogenic" bacteri…
HLA-B27-restricted cytotoxic T lymphocyte responses to arthritogenic enterobacteria or self-antigens are dominated by closely related TCRBV gene segm…
1996
Identification of the T-cell receptors (TCR) used by synovial cytotoxic T lymphocytes (CTL) of patients with reactive arthritis (ReA) may be crucial to better understanding the pathogenetic mechanism underlying the HLA-B27 association of spondylarthropathies. The authors, therefore, sequenced 25 TCRB chains from HLA-B27-restricted CD8+ CTL clones and two clonal lines specific for self- or Yersinia enterocolitica antigen isolated from synovial fluids of 3 HLA-B27+ patients with ReA and PBL of one healthy HLA-B27+ individual. Fourteen non-HLA-B27-restricted CTL served as controls. Both autoreactive and Y. enterocolitica specific HLA-B27-restricted CTL used a highly limited set of VB genes wit…

Efecto terapéutico del compuesto BO-110 en un modelo animal de leiomioma
2023
Los miomas son los tumores benignos más frecuentes en las mujeres en edad reproductiva y pueden asociar numerosos síntomas como dolor, sangrado y problemas reproductivos. Sin embargo, actualmente no existe una terapia totalmente satisfactoria por lo que es de suma importancia la evaluación de nuevos tratamientos. En la búsqueda de opciones terapéuticas alternativas, hemos seleccionado el ácido poliinosina-policitidílico (pIC) conjugado con polietilenimina (PEI) [pICPEI], cuyo nombre comercial es BO-100. El compuesto pIC es un ARN sintético de doble cadena sin toxicidad asociada, que induce de manera selectiva la autofagia y apoptosis en un gran espectro de células tumorales. Presen…

Les «Reflexions de la vellesa» d'Anna Murià, un cas singular
2018
L’article consta de dues parts. La primera és un recull exhaustiu d’obres sobre la vellesa al llarg de la història amb la finalitat de comprovar com ha estat considerada en la tradició literària occidental i poder establir paral·lelismes o diferències amb Reflexions de la vellesa. La segona part se centra en el dietari pòstum d’Anna Murià: el fet de reflexionar íntimament sobre l’ancianitat i tot allò que la concerneix, a partir de la pròpia experiència, contribueix a considerar la peça, des d’aquesta perspectiva, com una mostra única.
Modelling the removal and reversible immobilization of murine noroviruses in a Phaeozem under various contamination and rinsing conditions
2018
International audience; Enteric viruses entering the soil with contaminated irrigation water can reach groundwater or be internalized in plants through their roots without being inactivated. Their fate in the soil depends on the virus, the soil and the soil solution. In order to write a mathematical model suitable for a Calcaric Phaeozem, we investigated the removal of murine norovirus and reversible immobilization in aggregate columns according to a saturation procedure, conditions between contamination and rinsing time, temperature and soil solution. Viruses were quantified before and after 0.45‐μm filtration with an RT‐qPCR (real‐time polymerase chain reaction). Experimental results supp…
The effect of carvacrol on enteric viruses.
2014
Carvacrol, a monoterpenic phenol, is said to have extensive antimicrobial activity in a wide range of food spoilage or pathogenic fungi, yeast and bacteria. The aim of this study was to assess its antiviral activity on norovirus surrogates, feline calicivirus (FCV), murine norovirus (MNV), and hepatitis A virus (HAV), as well as its potential in food applications. Initially, different concentrations of carvacrol (0.25, 0.5, 1%) were individually mixed with each virus at titers of ca. 6-7 log TCID50/ml and incubated 2h at 37°C. Carvacrol at 0.5% completely inactivated the two norovirus surrogates, whereas 1% concentration was required to achieve ca. 1 log reduction of HAV. In lettuce wash wa…
