    Objetivo: Determinar si el uso del surfactante pulmonar es un factor protector para la enterocolitis necrotizante en neonatos prematuros en el Hospital Belén de Trujillo 2008-2018. Métodos y procedimientos: Estudio observacional, analítico, retrospectivo, de casos y controles. La población estuvo conformada por los neonatos prematuros de la Unidad de Cuidados Intensivos Neonatal del Hospital Belén de Trujillo durante el período 2008-2018. Se realizó un aleatorizado con 128 unidades de análisis divididas en 55 casos y 73 controles. Resultados: Del análisis estadístico se determinó que las variables sociodemográficas de peso, edad gestacional, APGAR 5’, uso de glucocorticoides, alimentación enteral no presentaron resultados estadísticamente significativos. Se encontró que aquellos pacientes que usaron surfactante pulmonar intratraqueal tuvieron 0.35 veces protección de tener ENC en comparación con los que no lo usaron (IC95% 0.44-0.97, p=0.036) Conclusiones: Se encontró que el uso de surfactante pulmonar es un factor protector para la enterocolitis necrotizante. Aquellos neonatos prematuros que recibieron surfactante intratraqueal presentaron protección de un 35% para no desarrollar enterocolitis necrotizante frente a los que no utilizaron surfactante intratraqueal.Objective: To determine if the use of pulmonary surfactant is a protective factor for necrotizing enterocolitis in preterm infants in the Hospital Belen de Trujillo 2008-2018. Materials and Methods: Observational, analytical, transversal, retrospective study. The population consisted of premature neonates of the Neonatal Intensive Care Unit of the Belen de Trujillo Hospital during the 2013-2018 period.

    BACKGROUND: Stevensite and biochar were investigated to covalently immobilize laccase from Myceliophthora thermophila (MtL) and Pleurotus eryngii (PeL) through the sequential application of aminopropyltriethoxysilane and glutaraldehyde. The immobilized preparations were tested to remove three tetracyclines and six sulfonamides at 0.1 mmol L−1 of each antibiotic. Degradation experiments were conducted both in the absence and in the presence (0.2 mmol L−1) of ABTS, 1-hydroxybenzotriazol (HBT), syringaldehyde or violuric acid. The residual antibiotic activity was tested towards five bacterial species and a bacterial consortium from wastewater. RESULTS: Higher values of activity yields (74% and 70.3%) and catalytic capabilities (1426 and 1405 IU g−1) were obtained with PeL on stevensite and biochar than with MtL. Stevensite enabled higher reusability and storage stability than biochar. Best removals of tetracyclines and sulfonamides were obtained with immobilized-laccase systems coupled to ABTS or syringaldehyde. Immobilized-laccase/ABTS systems removed 100% of tetracyclines while only chlortetracycline was completely removed in the presence of syringaldehyde. With ABTS, the most effectively removed sulfonamides were sulfathiazole and sulfadiazine (up to 100% and 54%), while syringaldehyde best supported the removal of sulfanilamide, sulfamethazine and sulfamethoxazole (up to 42%, 45% and 46%, respectively). In some cases, an effective antibiotics removal led to either low or no residual antibiotic activity. CONCLUSION: MtL and PeL were immobilized successfully on biochar and stevensite. The addition of either ABTS or syringaldehyde enhanced significant removals, up to 100%, of tetracyclines and sulfonamides by the immobilized laccase systems. Noteworthy, biochar-immobilized laccases/ABTS led to complete suppression of the antibiotic activity of tetracyclines. © 2018 Society of Chemical Industry

    Endogenous topoisomerase II-mediated DNA breaks drive thymic cancer predisposition linked to ATM deficiency

    Get PDF
    The ATM kinase is a master regulator of the DNA damage response to double-strand breaks (DSBs) and a well-established tumour suppressor whose loss is the cause of the neurodegenerative and cancer-prone syndrome Ataxia-Telangiectasia (A-T). A-T patients and Atm−/− mouse models are particularly predisposed to develop lymphoid cancers derived from deficient repair of RAG-induced DSBs during V(D)J recombination. Here, we unexpectedly find that specifically disturbing the repair of DSBs produced by DNA topoisomerase II (TOP2) by genetically removing the highly specialised repair enzyme TDP2 increases the incidence of thymic tumours in Atm−/− mice. Furthermore, we find that TOP2 strongly colocalizes with RAG, both genome-wide and at V(D)J recombination sites, resulting in an increased endogenous chromosomal fragility of these regions. Thus, our findings demonstrate a strong causal relationship between endogenous TOP2-induced DSBs and cancer development, confirming these lesions as major drivers of ATM-deficient lymphoid malignancies, and potentially other conditions and cancer types.Junta de Andalucía SAF2010-21017, SAF2013-47343-P, SAF2014-55532-R, SAF2017-89619-R, CVI-7948European Research Council ERC-CoG-2014-64735

    Implications of polluted soil biostimulation and bioaugmentation with spent mushroom substrate (Agaricus bisporus) on the microbial community and polycyclic aromatic hydrocarbons biodegradation

    Full text link
    Different applications of spent Agaricus bisporus substrate (SAS), a widespread agro-industrial waste, were investigated with respect to the remediation of a historically polluted soil with Polycyclic Aromatic Hydrocarbons (PAH). In one treatment, the waste was sterilized (SSAS) prior to its application in order to assess its ability to biostimulate, as an organic amendment, the resident soil microbiota and ensuing contaminant degradation. For the other treatments, two bioaugmentation approaches were investigated; the first involved the use of the waste itself and thus implied the application of A. bisporus and the inherent microbiota of the waste. In the second treatment, SAS was sterilized and inoculated again with the fungus to assess its ability to act as a fungal carrier. All these treatments were compared with natural attenuation in terms of their impact on soil heterotrophic and PAH-degrading bacteria, fungal growth, biodiversity of soil microbiota and ability to affect PAH bioavailability and ensuing degradation and detoxification. Results clearly showed that historically PAH contaminated soil was not amenable to natural attenuation. Conversely, the addition of sterilized spent A. bisporus substrate to the soil stimulated resident soil bacteria with ensuing high removals of 3-ring PAH. Both augmentation treatments were more effective in removing highly condensed PAH, some of which known to possess a significant carcinogenic activity. Regardless of the mode of application, the present results strongly support the adequacy of SAS for environmental remediation purposes and open the way to an attractive recycling option of this wasteThis work was financially supported by the Ministry of Science and Innovation of Spain (Project CTM2009-13140-C02-02

    Prescribed Burning and Clear-Cutting Effects on Understory Vegetation in a Pinus canariensis Stand (Gran Canaria)

    Get PDF
    [EN] Prescribed fires are a powerful tool for reducing fire hazards by decreasing amounts of fuel. The main objective is to analyze the effects of prescribed burning on the understory vegetation composition as well as on the soil characteristics of a reforested stand of Pinus canariensis. The study attempts to identify the effects of the preburning treatment of cutting understory vegetation on the floristic parameters of the vegetation community. This study was carried out for two years following a prescribed fire in a Canarian pine stand. Cutting and burning treatment affected species composition and increased diversity. Burnt and cut plots were characterized by a diverse array of herbaceous species and by a lower abundance of Teline microphylla (endemic legume), although burning apparently induced its germination. Cut treatment was more consistently differentiated from the control plots than burnt treatment. Soil K decreased after both treatments, pH slightly decreased after cutting, while P and Ca increased after fire. From an ecological point of view, prescribed burning is a better management practice than cutting the woody species of the understory. However, long-term studies would be necessary to evaluate the effects of fire intensity, season and frequency in which the prescribed burning is appliedSIConsejería de Medio Ambiente y Emergencias (Gran Canaria Council), especially UOFF and PRESA, for granting permission to work in Pinus canariensis forest, carrying out the prescribed fire, and partially supporting this study (CI02380503).

    Background: Studies have revealed controversial results regarding the diagnostic accuracy of plasma α-synuclein levels in patients with Parkinson’s disease (PD). This study was aimed to analyze the diagnostic accuracy of plasma α-synuclein in PD versus healthy controls and patients with essential tremor (ET). Methods: In this cross-sectional study, we included de novo (n = 19) and advanced PD patients [OFF (n = 33), and On (n = 35) states], patients with ET (n = 19), and controls (n = 35). The total plasma α-synuclein levels were determined using an ELISA sandwich method. We performed adjusted multivariate regression analysis to estimate the association of α-synuclein levels with group conditions [controls, ET, and de novo, OFF and ON-PD]. We studied the diagnostic accuracy of plasma α-synuclein using the area under the curve (AUC). Results: The plasma α-synuclein levels were higher in controls compared to PD and ET (p < 0.0001), discriminating de novo PD from controls (AUC = 0.74, 95% CI 0.60–0.89), with a trend towards in advanced PD (OFF state) from ET (AUC = 0.69, 95% CI 0.53–0.84). Conclusions: This is the first study examining and comparing plasma α-synuclein levels in ET vs. PD and controls. Preliminary findings suggest that plasma α-synuclein levels might help to discriminate de novo and advanced PD from controls and ET.Junta de Castilla y León is acknowledged for funding through the Biomedicine open project call (Ref.
