Screening a variable germplasm collection of Cucumis melo L. for seedling resistance to Macrophomina phaseolina
[EN] We evaluate the seedling resistance to charcoal rot caused by Macrophomina phaseolina in ninety-seven Cucumis melo accessions, from different geographical origins and five F1 generations, derived from crosses of five accessions selected for their resistance. Artificial inoculations with the toothpick method, previously reported to be useful for predicting shoot resistance, were performed, and plants were scored using a scale of disease severity. The average disease severity was calculated for each accession and was used to cluster the accession in five reaction classes. The screening revealed that sources of natural resistance to this fungus are limited. However, seedlings of seven accessions of different botanic groups displayed a resistant response to the stem inoculation, one cantaloup from Israel, one conomon accession from Korea, two wild agrestis and one acidulus from Africa, and two dudaim accessions from Middle East. The response of the F1 progenies varied from susceptibility to high resistance, the latter in progenies from the two agrestis wild types. These results suggest differences in the genetic basis of the resistance in the different selected sources. The resistant accessions are suggested to be screened under field conditions to confirm the level of resistance at adult plant stage and under stressful conditions.This work has been partially funded by the Project No 294/13 of the Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior CAPES (Brazil).

Biodegradable FeMnSi sputter-coated macroporous polypropylene membranes for the sustained release of drugs
Pure Fe and FeMnSi thin films were sputtered on macroporous polypropylene (PP) membranes with the aim to obtain biocompatible, biodegradable and, eventually, magnetically-steerable platforms. Room-temperature ferromagnetic response was observed in both Fe- and FeMnSi-coated membranes. Good cell viability was observed in both cases by means of cytotoxicity studies, though the FeMnSi-coated membranes showed higher biodegradability than the Fe-coated ones. Various strategies to functionalize the porous platforms with transferrin-Alexa Fluor 488 (Tf-AF488) molecules were tested to determine an optimal balance between the functionalization yield and the cargo release. The distribution of Tf-AF488 within the FeMnSi-coated PP membranes, as well as its release and uptake by cells, was studied by confocal laser scanning microscopy. A homogeneous distribution of the drug within the membrane skeleton and its sustained release was achieved after three consecutive impregnations followed by the addition of a layer made of gelatin and maltodextrin, which prevented exceedingly fast release. The here-prepared organic-inorganic macroporous membranes could find applications as fixed or magnetically-steerable drug delivery platforms
Brazilian melon landraces resistant to Podosphaera xanthii are unique germplasm resources
"This is the peer reviewed version of the following article: [FULL CITE], which has been published in final form at [Link to final article using the DOI]. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving."[EN] Podosphaera xanthii is the most important causal agent of powdery mildew
in melon, a crop ranked within the most economically important species
worldwide. The best strategy to face this fungus disease, which causes important
production losses, is the development of genetically resistant cultivars. Genetic
breeding programmes require sources of resistance, and a few ones have
been reported in melon, mostly in Momordica and Acidulus horticultural
groups. However, the existence of many races that reduces the durability of
the resistance makes necessary to find new resistant genotypes with different
genetic backgrounds.
In this work, Brazilian germplasm, together with a set of Indian landraces,
and the COMAV¿s (Institute for the Conservation and Breeding of Agricultural
Biodiversity) melon core collection, representing the whole variability of the
species, were assessed for resistance against some common races in Spain and
Brazil and genotyped with a 123-SNP (single nucleotide polymorphisms) genotyping
platform to study the molecular relationships of the resistant accessions.
In the first experiment, carried out in Valencia (Spain) in 2013, seventy-nine
melon accessions were evaluated using artificial inoculation. Five accessions
selected as resistant were also evaluated against races 1, 3, and 5 in Mossoró
(Brazil, 2015) and against race 3.5 in Valencia (2016) under greenhouse conditions,
and under four field conditions in Brazil. The accessions, AL-1, BA-3,
CE-3, and RN-2, within the Brazilian collection, presented resistance against
all the races of P. xanthii assayed in all conditions tested. AL-1, CE-3 and RN-2
were molecularly more similar to wild agrestis and Acidulus melons from Asia
and Africa, while BA-3 grouped with Momordica types. Molecular analysis also
confirmed that these new Brazilian sources of resistance differ from those previously
reported, constituting interesting materials to encourage genetic breeding
programmes, especially in Brazil and Spain.This work was supported by the Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq ( Processes: 485739/2013-5; 312315/2013-9) and CAPES-DPGU (294/2013) and by the projects funded by the Ministerio de Economia y Competitividad AGL2014-53398-C2-1-R and AGL2014-53398-C2-2-R (jointly funded by FEDER).

Permeable reactive barriers for the remediation of groundwater in a mining area: results for a pilot-scale project
The Sierra Minera of Cartagena-La Union is located in the Region of Murcia, Southeast of Spain. This zone presents high levels of heavy metals due to natural, geogenic reasons. In addition, the prolonged mining activity, and subsequent abandonment of farms, has had consequences on the environment, including severe affectation of the groundwater in the area. To remediate this situation, the Permeable Reactive Barrier (PRB) technology was assayed, which required in addition to the hydro-geological study of the zone, a careful optimization study for the design and construction of PRBs. For such a purpose a pilot-scale project was developed, and this communication reports some of the most relevant findings obtained after a four-years monitorization period. The selected reactive material for the PRBs was limestone filler. The filler is a waste material produced in many factories in the zone. These residues have good adsorption properties, high alkalinity, low cost and high availability, which make them suitable for use in remediation. The PRB was constituted by a 50% limestone filler and 50% sand, a proportion optimized by means of independent batch experiments. A layer of gravel was placed at the top, and on it a layer of natural soil. The barrier was designed in the form of a continuous trench, because the level of the contaminated groundwater was not very deep. In this way, the barrier could be prepared with standard excavation equipment. Parallel to the barrier, 6 wells where arranged downstream for sample collection. The pH and conductivity of the samples was measured directly in situ, and the content of Zn, Cd, Cu, Fe, and Pb were analyzed in the laboratory. All the samples collected after the PRB was constructed had basic pH values between 7.5 and 8. The conductivity was between 5 and 11 mS / cm except for the well 4, which had a value of 3.70 mS / cm. The concentration values of trace elements were below the detection limit (atomic absorption measurement) in most of cases, or showed values below normal levels of the area. Our results prove that limestone filler is suitable as the active component of PRBs barriers for sites polluted by trace elements. Following this relatively simple technology, there is no risk for human health or ecosystem, and a big cost-saving can be obtained in projects focused to the remediation of areas affected by mining activities
Boceprevir plus pegylated interferon/ribavirin to re-treat hepatitis C virus genotype 1 in HIV-HCV co-infected patients: final results of the Spanish BOC HIV-HCV Study
Introduction Boceprevir (BOC) was one of the first oral inhibitors of hepatitis C virus (HCV) NS3 protease to be developed. This study assessed the safety and efficacy of BOC + pegylated interferon-α2a/ribavirin (PEG-IFN/RBV) in the retreatment of HIV-HCV co-infected patients with HCV genotype 1. Methods This was a phase III prospective trial. HIV-HCV (genotype 1) co-infected patients from 16 hospitals in Spain were included. These patients received 4 weeks of PEG-IFN/RBV (lead-in), followed by response-guided therapy with PEG-IFN/RBV plus BOC (a fixed 44 weeks was indicated in the case of cirrhosis). The primary endpoint was the sustained virological response (SVR) rate at 24 weeks post-treatment. Efficacy and safety were evaluated in all patients who received at least one dose of the study drug. Results From June 2013 to April 2014, 102 patients were enrolled, 98 of whom received at least one treatment dose. Seventy-three percent were male, 34% were cirrhotic, 23% had IL28b CC, 65% had genotype 1a, and 41% were previous null responders. The overall SVR rate was 67%. Previous null-responders and cirrhotic patients had lower SVR rates (57% and 51%, respectively). Seventy-six patients (78%) completed the therapy scheme; the most common reasons for discontinuation were lack of response at week 12 (12 patients) and adverse events (six patients). Conclusions Response-guided therapy with BOC in combination with PEG-IFN/RBV led to an overall SVR rate of 67%, but an SVR rate of only 51% in patients with cirrhosis. The therapy was generally well tolerated. Although the current standards of care do not include BOC + PEG-IFN/RBV, the authors believe that this combination can be beneficial in situations where new HCV direct antiviral agent interferon-free therapies are not available yet
Feasibility and outcomes after dose reduction of immunochemotherapy in young adults with Burkitt lymphoma and leukemia: results of the BURKIMAB14 trial
High dose -intensive or infusional intermediate -dose immunochemotherapy is highly effective treatment for Burkitt lymphoma irrespective of human immunodeficiency virus (HIV) infection. However, toxicities of these regimens are relevant, especially in older adults and elderly patients. The prospective multicenter BURKIMAB14 trial included four to six blocks of immunochemotherapy according to stage (localized: 1 and 2 non -bulky; advanced: 2 bulky, 3, 4) and age, with dose reduction in patients >55 years old. Dose -intensity of chemotherapy was reduced in patients 55 years old had a significantly higher treatment -related mortality despite dose reduction of chemotherapy. With a median follow-up of 3.61 years the 4 -year OS probability was 73% (range, 63-81%). Age (55 years) and stage (localized vs. advanced) had prognostic significance. No significant differences in OS were observed in HIV -positive versus HIV -negative patients. The results of BURKIMAB14 are similar to those of other dose -intensive immunochemotherapy trials. Age >55 years and advanced stage, but not HIV infection, were associated with poor survival. Dose reduction of chemotherapy in young adults in CMR is safe and does not impact outcomes (clinicaltrials gov. Identifier: NCT05049473)

Escorxador; Porcí; Carn; Control oficialMatadero; Porcino; Carne; Control oficialSlaughterhouse; Swine; Meat; Official controlLa inspecció post mortem que efectua el col·lectiu de veterinaris oficials d’escorxador és una part important dels controls oficials relatius a la carn fresca i, com a tal, és un dels elements que condiciona que es dictamini com a apta o no per al consum humà i que s’hagin de notificar les malalties de declaració obligatòria.
Els escorxadors són entorns òptims per observar i registrar les particularitats de la variada patologia animal que s’hi presenta. Aquesta informació, si és compartida, pot esdevenir una eina molt útil i interessant per al col·lectiu de professionals.
En conseqüència, es va crear una comunitat de pràctica (CoP) per a l’espècie porcina.
L’autoria d’aquest manual és de veterinaris oficials d’escorxador de la Generalitat de Catalunya. El contingut s’ha volgut transmetre per mitjà de fitxes que contenen informació científica, tècnica i legal per a cada una de les malalties i lesions que s’hi descriuen. Alhora, les fitxes s’il·lustren amb imatges obtingudes als diferents escorxadors de Catalunya. Així, doncs, sabem que els manuals es presenten encara incomplets i, per això, es preveu poder completar-los en futures edicions.La inspección post mortem que efectúa el colectivo de veterinarios oficiales de matadero es una parte importante de los controles oficiales relativos a la carne fresca y, como tal, es uno de los elementos que condiciona que se dictamine como apta o no para el consumo humano y que deban notificarse las enfermedades de declaración obligatoria.

Slaughterhouses are optimal environments to observe and record the particularities of the varied animal pathology that occurs. This information, if shared, can become a very useful and interesting tool for the group of professionals.
Accordingly, a community of practice (CoP) for swine was created.
The authorship of this manual is official slaughterhouse veterinarians of the Generalitat de Catalunya. The content has been conveyed through sheets containing scientific, technical and legal information for each of the diseases and injuries described. Likewise, the sheets are illustrated with images obtained in the different slaughterhouses in Catalonia. Thus, we know that the manuals are still incomplete and, therefore, it is expected to be able to complete them in future editions
HTLV-1 infection in solid organ transplant donors and recipients in Spain
HTLV-1 infection is a neglected disease, despite infecting 10-15 million people worldwide and severe illnesses develop in 10% of carriers lifelong. Acknowledging a greater risk for developing HTLV-1 associated illnesses due to immunosuppression, screening is being widely considered in the transplantation setting. Herein, we report the experience with universal HTLV testing of donors and recipients of solid organ transplants in a survey conducted in Spain. All hospitals belonging to the Spanish HTLV network were invited to participate in the study. Briefly, HTLV antibody screening was performed retrospectively in all specimens collected from solid organ donors and recipients attended since the year 2008. A total of 5751 individuals were tested for HTLV antibodies at 8 sites. Donors represented 2312 (42.2%), of whom 17 (0.3%) were living kidney donors. The remaining 3439 (59.8%) were recipients. Spaniards represented nearly 80%. Overall, 9 individuals (0.16%) were initially reactive for HTLV antibodies. Six were donors and 3 were recipients. Using confirmatory tests, HTLV-1 could be confirmed in only two donors, one Spaniard and another from Colombia. Both kidneys of the Spaniard were inadvertently transplanted. Subacute myelopathy developed within 1 year in one recipient. The second recipient seroconverted for HTLV-1 but the kidney had to be removed soon due to rejection. Immunosuppression was stopped and 3 years later the patient remains in dialysis but otherwise asymptomatic. The rate of HTLV-1 is low but not negligible in donors/recipients of solid organ transplants in Spain. Universal HTLV screening should be recommended in all donor and recipients of solid organ transplantation in Spain. Evidence is overwhelming for very high virus transmission and increased risk along with the rapid development of subacute myelopathy
