Modulation of immune responses of Rhynchophorus ferrugineus (Insecta: Coleoptera) induced by the entomopathogenic nematode Steinernema carpocapsae (N…
2014
Aim of this study was to investigate relationships between the red palm weevil (RPW) Rhynchophorus ferrugineus (Olivier) and the entomopathogenic nematode Steinernema carpocapsae (EPN); particularly, the work was focused on the immune response of the insect host in naive larvae and after infection with the EPN. Two main immunological processes have been addressed: the activity and modulation of host prophenoloxidase-phenoloxidase (proPO) system, involved in melanization of not-self and hemocytes recognition processes responsible for not-self encapsulation. Moreover, immune depressive and immune evasive strategies of the parasite have been investigated. Our results suggest that RPW possess a…
Chitosomes loaded with cranberry proanthocyanidins attenuate the bacterial lipopolysaccharide-induced expression of iNOS and COX-2 in raw 264.7 macro…
2009
Chitosan binds to negatively charged soy lecithin liposomes by an electrostatic interaction driven by its positively charged amino group. This interaction allows stable covered vesicles (chitosomes) to be developed as a suitable targeted carrier and controlled release system. This study investigated the effect of chitosomes on the activation of cranberry proanthocyanidins (PAC) in Raw 264.7 macrophages. Chitosomes were characterized according to size, zeta potential, PAC-loading, and release properties. Results showed an increase in the net positive charge and size of the liposomes as the concentration of chitosan was increased, suggesting an effective covering of the vesicles by means of e…

Les spectres carpologiques provenant des puits du haut Moyen Âge : réflexions sur la mise au point d’un protocole d’étude à partir de deux exemples, …
2016
RésuméLes couches humides des puits sont souvent étudiées d’un point de vue carpologique. Cet article présente quelques réflexions et suggestions concernant l’échantillonnage, le traitement des prélèvements et la présentation des résultats carpologiques provenant de ces couches humides, généralement riches en macrorestes végétaux. Les plantes cultivées sont classées dans les tableaux par grands groupes fonctionnels (céréales, légumineuses, plantes oléagineuses et à fibres, fruitiers cultivés, etc.) et les taxons sauvages sont regroupés à partir de classes syntaxinomiques. Nous adoptons l'encodage syntaxinomique proposé par Ellenberg et al. . Enfin, une charte graphique cohérente est proposé…
Metacarpophalangeal joint of the thumb arthrodesis using intramedullary interlocking screws XMCP™
2018
Abstract The study objective was to assess the results of a thumb metacarpophalangeal joint (MCPJ) arthrodesis using intramedullary interlocking screws at 25°, XMCP ™ (Extremity Medical, Parsippany, NJ). Radiographs evaluated the angle of arthrodesis, time of fusion and fixation of the implant. Clinical and functional outcomes were assessed using the DASH questionnaire and the VAS scale. Any complications found during surgery or the follow-up period were noted. We studied 9 patients. The mean follow-up was 27.6 months. Patients showed clinical and radiological evidence of fusion in an average of 8 weeks, the angle of fusion was 25°. There were no complications and no implant had to be remov…
Chimeric Free Vascularized Metatarsophalangeal Joint With Toe Fillet Flap: A Technique for Reconstruction of the Posttraumatic Metacarpophalangeal Jo…
2018
For painful, dysfunctional, posttraumatic metacarpophalangeal (MCP) joints, the free vascularized toe joint transfer may represent a good solution. Successful reconstruction is potentially limited, however, by 2 features of the traditional vascularized metatarsophalangeal (MTP) transfer: inadequate arc of flexion and insufficient soft tissue coverage. The solution to both of these dilemmas lies in the manner of utilizing the donor site. Because of its innate hyperextensibility, rotating the MTP 180° volar to dorsal provides the greatest arc of flexion in the reconstructed MCP. Excellent soft tissue coverage can be provided by elevating the skin paddle of the transferred second toe as a chim…

“If you seek it, you will find it”. Methodology for the carpological study of the Middle Magdalenian of Cova de les Cendres site (Teulada-Moraira, Al…
2016
La carpología, el estudio de los frutos, semillas, tubérculos, rizomas y bulbos recuperados en yacimientos arqueológicos, ha sido aplicada mayoritariamente a contextos correspondientes a sociedades productoras, mientras que los estudios carpológicos de yacimientos de cazadores-recolectores son escasos. En los últimos años, estos han experimentado un incremento, desvelándose el valor de la información que proporcionan: económica, cultural, botánica y ecológica. Presentamos en este artículo la metodología aplicada para el análisis carpológico de un conjunto de muestras procedentes de un nivel fechado en el Magdaleniense medio de la Cova de les Cendres (Teulada-Moraira, Alicante).
