El implante de condrocitos autólogos en la red sanitaria pública de Andalucía. Resultados tras 6 años de circuito asistencial.

Objective: To asses the results of Autologous Chondrocyte Implantation (ACI) whith periosteal patch and To propagate the care circuits existing about in Andalusia. Material and Methods: From its of ficial licence in 2005, the tissue bank and the Virgen de la Victoria Hospital from Málaga, performed the ACI in the Andalusian public health system. 16 patients has been operated between 2006-2013, whith medium follow-up 47,6 months (6 months-6 years), from public hos- pitals throughout Andalucia, managed by hospital admission source and destination. Physiologically younger patients were selected (<50 años), with singles, > 2cm2 symptomatics chondral lesions, in stables and well aligned knees. ACI was used as res- cue procedure after microfracture ́s failure except osteochondritis dissecans. To assess the results the Concinnati score and the Short Form 36 (SF-36) score were used. A descriptive analysis was performed and non-parametric tests were used to establish correlations and compare results. Results: In 15 patients with more than one year of follow-up: 14 men(87.5%) and 2women (14.5%), medium age 28.2 years old (min 17 max 43), the lesion was located into de femoral condyle, mostly in the internal one (81,2%) with medium size 2,7cm2(2-4,2). We founded significant improvement (p<0,001), both daily activities ( 89,3% preop. limitatión - 9% postop), as in the sports (90,2% preop limitatión - 38% postop) and the exploration of the knee (67,7% hpatological findings preop- 13,3%postop). The SF-36 score improved in all categories, over all in mental health (p> 0,01). The patient satisfaction was high or very high in 12 of the 15 patients ( 80%), and low in 3 patients. Conclusions: ACI improve quality of life and knee function in femoral condyle chondral lesions. The case ́s selection and the collaboration with Tissue Bank, allows us to create care circuits for treatment of patients from other provinces in the Public Sanitary Health System in Andalucia. It is necessary to increase the experience with this type of therapy, consolidating multicenter workgroups that provide strength to the conclusions.

Antibody recognition of Plasmodium falciparum infected red blood cells by symptomatic and asymptomatic individuals in the Brazilian Amazon

In the Amazon Region, there is a virtual absence of severe malaria and few fatal cases of naturally occurring Plasmodium falciparum infections; this presents an intriguing and underexplored area of research. In addition to the rapid access of infected persons to effective treatment, one cause of this phenomenon might be the recognition of cytoadherent variant proteins on the infected red blood cell (IRBC) surface, including the var gene encoded P. falciparum erythrocyte membrane protein 1. In order to establish a link between cytoadherence, IRBC surface antibody recognition and the presence or absence of malaria symptoms, we phenotype-selected four Amazonian P. falciparum isolates and the laboratory strain 3D7 for their cytoadherence to CD36 and ICAM1 expressed on CHO cells. We then mapped the dominantly expressed var transcripts and tested whether antibodies from symptomatic or asymptomatic infections showed a differential recognition of the IRBC surface. As controls, the 3D7 lineages expressing severe disease-associated phenotypes were used. We showed that there was no profound difference between the frequency and intensity of antibody recognition of the IRBC-exposed P. falciparum proteins in symptomatic vs. asymptomatic infections. The 3D7 lineages, which expressed severe malaria-associated phenotypes, were strongly recognised by most, but not all plasmas, meaning that the recognition of these phenotypes is frequent in asymptomatic carriers, but is not necessarily a prerequisite to staying free of symptoms.

Genetic consequences of the ice ages on nurseries of the bat Myotis myotis: a mitochondrial and nuclear survey.

Analyses of mitochondrial DNA (mtDNA) control region polymorphism and of variation at 10 nuclear microsatellite loci were used to investigate the mechanisms and genetic consequences of postglacial expansion of Myotis myotis in Europe. Initial sampling consisted of 480 bats genotyped in 24 nursery colonies arranged along a transect of approximately 3000 km. The phylogeographical survey based on mtDNA sequences revealed the existence of major genetic subdivisions across this area, with several suture zones between haplogroups. Such zones of secondary contact were found in the Alps and Rhodopes, whereas other potential barriers to gene flow, like the Pyrenees, did not coincide with genetic discontinuities. Areas of population admixture increased locally the genetic diversity of colonies, which confounded the northward decrease in nucleotide diversity predicted using classical models of postglacial range expansion. However, when analyses were restricted to a subset of 15 nurseries originating from a single presumed glacial refugium, mtDNA polymorphism did indeed support a northwards decrease in diversity. Populations were also highly structured (PhiST = 0.384). Conversely, the same subset of colonies showed no significant latitudinal decrease in microsatellite diversity and much less population structure (FST = 0.010), but pairwise genetic differentiation at these nuclear markers was strongly correlated with increasing geographical distance. Together, this evidence suggests that alleles carried via male bats have maintained enough nuclear gene flow to counteract the effects of recurrent bottlenecks generally associated with recolonization processes. As females are highly philopatric, we argue that the maternally transmitted mtDNA marker better reflects the situation of past, historical gene flow, whereas current levels of gene flow are better reflected by microsatellite markers.

The energetic grooming costs imposed by a parasitic mite (Spinturnix myoti) upon its bat host (Myotis myotis).

Parasites often exert severe negative effects upon their host's fitness. Natural selection has therefore prompted the evolution of anti-parasite mechanisms such as grooming. Grooming is efficient at reducing parasitic loads in both birds and mammals, but the energetic costs it entails have not been properly quantified. We measured both the energetic metabolism and behaviour of greater mouse-eared bats submitted to three different parasite loads (no, 20 and 40 mites) during whole daily cycles. Mites greatly affected their time and energy budgets. They caused increased grooming activity, reduced the overall time devoted to resting and provoked a dramatic shortening of resting bout duration. Correspondingly, the bats' overall metabolism (oxygen consumption) increased drastically with parasite intensity and, during the course of experiments, the bats lost more weight when infested with 40 rather than 20 or no parasites. The short-term energetic constraints induced by anti-parasite grooming are probably associated with long-term detrimental effects such as a decrease in survival and overall reproductive value.

Molecular markers allow sibling species identification in red wood ants (Formica rufa group)

Red wood ants (Formica rufa group) constitute a group of species that are considered to be among the most promising bioindicators in forest ecosystems. However, because of their morphological similarity and intraspecific variability, morphological species identification can be difficult. Considerable expertise is necessary to discriminate between the sibling species F. lugubris and F. paralugubris, two species that often live in sympatry in the same Alpine forests. New taxonomic tools providing rapid and reliable species identification are needed. We present a simple and reliable molecular technique based on mtDNA (COI gene) and a restriction enzyme for discriminating between F. lugubris and F. paralugubris. We confirm the validity of this method with a Bayesian analysis based on microsatellites. This new molecular tool represents a clear breakthrough for discriminating between F. lugubris and F. paralugubris and is likely to be helpful in large-scale biomonitoring.

RED BLOOD CELL MICROPARTICLES: ROLE IN TRANSFUSION MEDICINE?

RésuméLes microparticules sont des vésicules phospholipidiques de moins d‟un micromètre relâchées dans le sang par différents types cellulaires, comme les cellules endothéliales, les plaquettes ou encore les globules blancs et rouges. Elles sont bioactives et impliquées dans de nombreux processus physiologiques incluant l‟hémostase. De plus, un nombre élevé de microparticules circulantes dans le sang a été observé dans différentes pathologies.Dans le domaine de la transfusion, les microparticules de globules rouges ont été détectées dans les concentrés érythrocytaires. Le but de cette recherche était de caractériser les microparticules de globules rouges et d‟évaluer si ces dernières avaient un rôle en transfusion. Pour ce faire, une approche globale utilisant différentes techniques comme la cytométrie de flux, la protéomique, la microscopie ainsi que des tests d‟hémostase de routines, a été adoptée.Le présent travail de thèse a démontré que les microparticules de globules rouges s‟accumulent dans les concentrés érythrocytaires pendant le stockage. Leur bioactivité a été démontrée de part leur rôle actif dans le processus de la coagulation. En effet, lors de test de génération de thrombine, elles peuvent non seulement supporter ce processus de coagulation, mais aussi le déclencher par un mécanisme inconnu sous certaines circonstances. Les microparticules de globules rouges présentent aussi des antigènes de groupes sanguins à leur surface, toutefois, leur implication potentielle dans l‟induction d‟une réponse immunitaire n‟est pas connue. Bien que le mécanisme de formation et d‟émissions des microparticules par les globules rouges ne soit pas complètement élucidé, il a été démontré qu‟elles n‟ont pas toutes le même contenu protéique et donc qu‟elles pourraient avoir des fonctions différentes.Au vu des résultats, notamment par leur implication dans la coagulation, il est fort probable que la présence de microparticules puisse affecter la qualité des produits sanguins, et causer des réactions transfusionnelles.
