    Abstract Background No data on circulating biomarkers for the prognostic stratification of Malignant Pleural Mesothelioma (MPM) patients are available. We prospectively explored the prognostic role of circulating monocyte and cytokine levels and their dynamic change during chemotherapy. Patients and Methods MPM patients receiving a first line treatment based on a platinum compound plus pemetrexed were eligible. Blood samples were collected at the baseline and at the end of induction chemotherapy. CCL-2, IL-10 and TGF-β levels in plasma were quantified by Enzyme-Linked Immunosorbent Assay (ELISA); white blood cells, monocytes and platelets were evaluated by blood count test. Results Thirty-one patients were included in the study. Median overall survival (OS) was 12.13 months versus 9.6 months in patients with lower and higher monocytes count, respectively (p value = 0.02). We further stratified patients according to a combined score based on the association of IL-10, TGF-β levels and monocytes count. High combined score was associated with shorter OS and PFS in univariate and multivariate analysis. Chemotherapy induced an increase in monocytes, IL-10, but not TGF-β levels. Conclusion The prognostic value of circulating levels of multiple immunosuppressive cytokines and inflammatory cells should be confirmed in a wider validation set of MPM patients

    O objetivo deste trabalho foi avaliar fontes de fósforo em rações orgânicas, para alevinos e juvenis de tilápia‑do‑nilo. Utilizou-se o delineamento experimental inteiramente casualizado, com três tratamentos: farinha de resíduos de peixes, fosfato bicálcico e a combinação de ambos, com seis repetições. Duzentos e setenta alevinos e 180 juvenis foram distribuídos em tanques experimentais de 250 e 500 L, respectivamente, e alimentados com rações à base de ingredientes com certificação de origem orgânica contendo 32 e 28% de proteína bruta, respectivamente. Foram avaliados: qualidade da água de cultivo, índices zootécnicos e composição centesimal da carcaça dos peixes. As fontes de fósforo não influenciaram os parâmetros avaliados em alevinos. Juvenis alimentados com a dieta contendo farinha de resíduos de peixes obtiveram melhores índices zootécnicos, em comparação ao fosfato bicálcico, não tendo diferido da combinação entre as fontes. Os valores de fósforo na água ficaram acima dos preconizados pela Resolução 357/2005 do Conama. Para alevinos, é adequado utilizar farinha de resíduos de peixes, fosfato bicálcico ou sua combinação como principal fonte de fósforo e, para juvenis, é adequado utilizar farinha de resíduos de peixes ou a sua combinação com fosfato bicálcico, em rações orgânicas, para melhor desempenho produtivo.The objective of this work was to evaluate phosphorus sources in organic diets for fingerlings and juvenile Nile tilapia. The experimental design was a completely randomized block, with three treatments: fish waste meal, dicalcium phosphate, and their combination, with six replicates. Two hundred and seventy fingerlings and 180 juveniles were divided into experimental tanks of 250 and 500 L, respectively, and fed diets based on ingredients from certified organic origin containing 32 and 28% crude protein, respectively. Quality of water for cultivation, production indexes and proximate composition of fish carcass were evaluated. Phosphorus sources did not influence the evaluated parameters in fingerlings. Juveniles fed the diet containing fish waste meal had better biological indexes, compared to dicalcium phosphate and did not differ from their combination. The values of phosphorus in the water were above the recommended by the Resolution 357/2005 from Conama. For fingerlings, it is appropriate to use fish waste meal, dicalcium phosphate or its combination as the main source of phosphorus, and, for juveniles, it is appropriate to use fish waste meal or its combination with dicalcium phosphate in organic diets for better production performance

    Aiming to assess organic soybean meal (OSM) for Nile tilapia, two studies were carried out: Study I - digestibility of OSM compared to conventional soybean meal (CSM) for Nile tilapia; and Study II - effect of OSM and CSM, supplemented or not with fish meal (FM) on the performance of Nile tilapia fingerlings. The apparent digestibility coefficients of the protein were 88.24 and 88.10%, resulting in 39.91 and 39.87% digestible protein for OSM and CSM, respectively. The apparent digestibility coefficients of energy were 75.92 and 70.48%, resulting in 3579.46 and 3141.44 kcal kg-1 of digestible energy for OSM and CSM, respectively. The diet containing CSM+FM presented the best results for final weight and weight gain. However, the highest levels of crude protein in the fish carcass were observed in the animals fed with the OSM + FM diet. The OSM diet presented the best results for total protein and albumin in the blood. The OSM diet has good apparent digestibility coefficients and its use in tilapia feeding presents a satisfactory productive performance and a higher deposition of protein in the carcass when supplemented with 20% of fish meal

    Negative impacts of dominance on bee communities: Does the influence of invasive honey bees differ from native bees?

    Get PDF
    Invasive species can reach high abundances and dominate native environments. One of the most impressive examples of ecological invasions is the spread of the African subspecies of the honey bee throughout the Americas, starting from its introduction in a single locality in Brazil. The invasive honey bee is expected to more negatively impact bee community abundance and diversity than native dominant species, but this has not been tested previously. We developed a comprehensive and systematic bee sampling scheme, using a protocol deploying 11,520 pan traps across regions and crops for three years in Brazil. We found that invasive honey bees are now the single most dominant bee species. Such dominance has not only negative consequences for abundance and species richness of native bees but also for overall bee abundance (i.e., strong “numerical” effects of honey bees). Contrary to expectations, honey bees did not have stronger negative impacts than other native bees achieving similar levels of dominance (i.e., lack of negative “identity” effects of honey bees). These effects were markedly consistent across crop species, seasons and years, and were independent from land-use effects. Dominance could be a proxy of bee community degradation and more generally of the severity of ecological invasions.info:eu-repo/semantics/publishedVersio

    Safety and efficacy of low-dose sirolimus in the PIK3CA-Related Overgrowth Spectrum

    Purpose PIK3CA-related overgrowth spectrum (PROS) encompasses a range of debilitating conditions defined by asymmetric overgrowth caused by mosaic activating PIK3CA variants. PIK3CA encodes the p110α catalytic subunit of phosphatidylinositol-3-kinase (PI3K), a critical transducer of growth factor signaling. As mTOR mediates the growth-promoting actions of PI3K, we hypothesized that the mTOR inhibitor sirolimus would slow pathological overgrowth. Methods Thirty-nine participants with PROS and progressive overgrowth were enrolled into open-label studies across three centers, and results were pooled. For the primary outcome, tissue volumes at affected and unaffected sites were measured by dual energy X-ray absorptiometry during 26 weeks of untreated run-in and 26 weeks of sirolimus therapy. Results Thirty participants completed the study. Sirolimus led to a change in mean percentage total tissue volume of –7.2% (SD 16.0, p = 0.04) at affected sites, but not at unaffected sites (+1.7%, SD 11.5, p = 0.48) (n = 23 evaluable). Twenty-eight of 39 (72%) participants had ≥1 adverse event related to sirolimus of which 37% were grade 3 or 4 in severity and 7/39 (18%) participants were withdrawn consequently. Conclusion This study suggests that low-dose sirolimus can modestly reduce overgrowth, but cautions that the side-effect profile is significant, mandating individualized risk–benefit evaluations for sirolimus treatment in PROS
