Manganese Defective Clustering: Influence on the Spectroscopic Features of Ceria-Based Nanomaterials.

The influence of manganese modification on the spectroscopic features of manganese-doped CeO2 systems synthesized by the microwave-assisted hydrothermal route and their correlation with the presence of O defective structures were verified, focusing on their interaction with poisonous atmospheres. Raman and electron paramagnetic resonance studies confirmed the presence of defective clusters formed by dipoles and/or quadrupoles. The number of paramagnetic species was found to be inversely proportional to the doping concentration, resulting in an increase in the Mn2+ signal, likely due to the reduction of Mn3+ species after the interaction with CO. X-ray photoelectron spectroscopy data showed the pure system with 33% of its cerium species in the Ce3+ configuration, with an abrupt decrease to 19%, after the first modification with Mn, suggesting that 14% of the Ce3+ species are donating one electron to the Mn2+ ions, thus becoming nonparamagnetic Ce4+ species. On the contrary, 58% of the manganese species remain in the Mn2+ configuration with five unpaired electrons, corroborating the paramagnetic feature of the samples seen in the electron paramagnetic resonance study.

Linfoma no Hodgkin difuso de células B grande como linfoma primario de ovario. Presentación decaso / Diffuse large B-cell non-Hodgkin's lymphoma as primary ovarian lymphoma. Case presentation

Fundamento: Los linfomas primarios de ovario son poco frecuentes; el 1porciento de estos se presenta en ovario y el 1.5 porciento de los tumores malignos de ovario son linfomas. Los tipos histológicos más frecuenteses el linfoma no Hodgkin difuso de células B grande y el BurKitt; el tratamiento consiste en cirugía combinada con quimioterapia.Objetivo: Reportar un caso de un linfoma no Hodgkin difuso de células B grande primario de ovario. Presentación de caso: Se presentó el caso de una paciente de 39 años de edad, con antecedentes patológicos personales de salud; la cual fue al cuerpo de guardia de ginecología por presentar dolor abdominal difuso que no se aliviaba con analgésicos. En la exploración física presentaba dolor a la palpación superficial y profunda en hipocondrio y fosa ilíaca derecha con masa tumoral palpable. Ecografía hacia proyección anexial derecha se observó una imagen de baja ecogenicidad y en la laparoscopia de urgencia se concluyó como una formación de aspecto tumoral que parecía corresponderse con ovario derecho. Se le realizó una histerectomía con doble anexectomía. El diagnóstico anatomopatológico fue un linfoma no Hodgkin primario de ovario.Conclusiones: La paciente del caso presentado tuvo una clínica oligosintomática y la confirmación de la enfermedad fue a partir de una muestra quirúrgica, lo que expresa que el diagnóstico del linfoma no Hodgkin de células B es difícil y aunque es poco frecuente siempre se debe tener en cuenta en el diagnóstico diferencial de las tumoraciones unilaterales de ovario.

Tratamiento farmacológico y no farmacológico. Adherencia e inercia terapéutica / Pharmacological and non-pharmacological treatment. Adherence and therapeutic inertia

La hipertensión arterial (HTA) continúa siendo el principal factor evitable de enfermedad cardiovascular (ECV) y de mortalidad por cualquier causa tanto en Europa como en el mundo y existe una gran cantidad de evidencias que demuestran que la reducción de la presión arterial (PA) reduce sustancialmente la morbimortalidad prematura1.El objetivo de reducir la presión arterial de nuestros pacientes radica fundamentalmente en frenar la evolución de la enfermedad arteriosclerótica y sus complicaciones cardiovasculares y renales, entre otras.En estos momentos contamos con dos estrategias terapéuticas que han demostrado un beneficio claro sobre la ECV: las intervenciones en el estilo de vida y el tratamiento farmacológico. No hay duda de que las intervenciones en el estilo de vida pueden reducir la PA y deben indicarse en todos los casos, aunque su impacto no sea tan potente como el tratamiento farmacológico1.Dado que los tratamientos de los factores de riesgo cardiovascular (FRCV) se prolongarán durante décadas, es importante que sean bien tolerados además de efectivos e impacten de forma positiva en la calidad de vida de los pacientes.

GC-MS determination of malondialdehyde, acrolein, and 4-hydroxy-2-nonenal by ultrasound-assisted dispersive liquid-liquid microextraction in beverages.

A new, fast, simple, and effective ultrasound-assisted dispersive liquid-liquid microextraction procedure (UA-DLLME) for the gas chromatography-mass spectrometry (GC-MS) determination of malondialdehyde, acrolein, and 4-hydroxy-2-nonenal in beverages was successfully developed. 2,4-Dinitrophenylhydrazine derivatization was performed during extraction. An asymmetrical 3541//18 screening design and a central composite surface response design were used to investigate the influence of the most critical factors during the extraction process (ultrasound time and temperature, extraction and disperser solvents volumes, salt addition, and derivatization reagent concentration). According to FDA guidelines, the method was validated, achieving good linearities with r2 ≥ 0.9982, recoveries between 94.0 and 102.4%, and reproducibility with RSD lower than 4.5%. The method was applied to simultaneously determine the compounds in 60 different beverage samples, including beer, coffee, black tea, and fruit juices. The presence of secondary lipid oxidation products is demonstrated in beverages with a strong roasting process or oxidation.

In vivo CRISPR/Cas9 targeting of fusion oncogenes for selective elimination of cancer cells.

Fusion oncogenes (FOs) are common in many cancer types and are powerful drivers of tumor development. Because their expression is exclusive to cancer cells and their elimination induces cell apoptosis in FO-driven cancers, FOs are attractive therapeutic targets. However, specifically targeting the resulting chimeric products is challenging. Based on CRISPR/Cas9 technology, here we devise a simple, efficient and non-patient-specific gene-editing strategy through targeting of two introns of the genes involved in the rearrangement, allowing for robust disruption of the FO specifically in cancer cells. As a proof-of-concept of its potential, we demonstrate the efficacy of intron-based targeting of transcription factors or tyrosine kinase FOs in reducing tumor burden/mortality in in vivo models. The FO targeting approach presented here might open new horizons for the selective elimination of cancer cells.

[Bronchospasm and flushing after vaccination with 23 serotype pneumococcal polysaccharide in chronic patients]. / Broncoespasmo y flushing tras la vacunación con neumococo polisacárida de 23 serotipos en pacientes crónicos.

OBJECTIVE: To describe the clinical-epidemiological characteristics of a series of suspected systemic adverse reactions registered with the 23 serotype pneumococcal polysaccharide vaccine (PNEUMOVAX23®). Calculate the cumulative incidence of the reaction and know if similar and/or compatible cases have been described in the scientific literature or in pharmacovigilance. METHODS: Observational and retrospective study realized between 01/12/2015 and 30/09/2017 in the Vaccines Unit of an autonomic reference hospital. We calculated the cumulative incidence of the adverse reaction for that vaccine. The common pharmacovigilance database (FEDRA) was consulted. RESULTS: Nine systemic adverse reactions were recorded (flushing + bronchospasm + SatO2<95%). The cumulative incidence was 1.036%. The outcome was recovered/resolved for everyone. No similar and/or compatible cases were found. CONCLUSIONS: The reactions described do not appear in the PNEUMOVAX23® data sheet. Epidemiologically, no causal relationship can be established between the symptoms and the variables studied. This study could be the basis for more detailed research that could modify the vaccine data sheet.

Development of a partitioned liquid-liquid extraction- dispersive solid phase extraction procedure followed by liquid chromatography-tandem mass spectrometry for analysis of 3-monochloropropane-1,2-diol diesters in edible oils.

A fast and effective method using a modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) approach which includes partitioned liquid-liquid extraction (PLLE) and dispersive solid phase extraction (dSPE) clean-up step for the determination of seven 3-monochloropropane-1,2-diol (3-MCPD) fatty acid diesters in vegetable oils is developed and validated according to the Food and Drug Administration (FDA) guidelines. Due to the complexity of the matrices, combination of silica based sorbents (Silica Strong Anion Exchange (Si-SAX), Supel™ QuE Z-Sep+ (Z-Sep+) and Primary Secondary Amine (PSA) were tested for lipid removal. The effect of several experimental factors on the efficiency of the extraction procedure was studied by a screening design 3422//16 and a response surface Doehlert design. The separation and determination was carried out by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). The method provided suitable linearity (r2 > 0.9960), precision (relative standard deviation (RSD) lower than 10%) and accuracy, in terms of recovery. The limits of detection (LOD) and limits of quantification (LOQ) ranged from 10 to 20 µg kg -1 and from 25 to 50 µg kg-1, respectively. The recoveries at three spiking levels of 100, 250, and 500 µg kg-1 were over the range of 71.4-122.9% with RSD lower than 13%. The method was successfully applied in edible oils and fatty food samples. The results provide valuable information to assess the risk of exposure to these foodborne contaminants.

Comparação entre três métodos analíticos para determinação de soro em leite cru refrigerado / Comparison of three analytical methods to determine serum in refrigerated raw milk

O objetivo deste experimento foi comparar três métodos analíticos para determinação de soro em leite cru refrigerado: cromatografia líquida de alta eficiência, ninidrina ácida e colorimétrico adaptado. Foram coletadas 100 amostras de leite cru refrigerado de tanques de expansão. Estas, quando submetidas à análise pelo método da ninidrina ácida, apresentaram 10 (14,7%) amostras negativas e 58 (85,3%) positivas. O teor médio de ácido siálico encontrado na técnica da ninidrina foi de 5,58(g/mL, com valor mais frequente de 2,70(g/mL. Das 68 amostras negativas pela cromatografia líquida de alta eficiência, duas foram positivas (2,94%) e 66 (97,06%) negativas, quando analisadas pelo método colorimétrico. A frequência relativa de amostras positivas foi de 32%, com a CLAE apresentando a maior média de soro (14,37%), seguida do método colorimétrico (5,28%) e o da ninidrina ácida (3,12%). A técnica de cromatografia líquida de alta eficiência diferiu dos métodos de ninidrina ácida e colorimétrico, enquanto os métodos da ninidrina e colorimétrico não diferiram entre si, podendo ambos serem utilizados como metodologias de triagem. Entre as três técnicas, a cromatografia líquida de alta eficiência foi a metodologia mais sensível na detecção e quantificação do soro em leite cru refrigerado.(AU)

The objective of this study was to compare three analytical methods to determine serum in refrigerated raw milk. High-performance liquid chromatography (HPLC), acidic and colorimetric ninhydrin methods were applied. A collection of 100 samples of raw milk from cooled expansion tanks took place. The results showed that 10 samples (14.7%) were negative and 58 (85.3%) were positive for the acidic ninhydrin method. The mean sialic acid content found in the ninhydrin technique was 5.58µg/mL, with a more frequent value of 2.70µg/mL. From all 68 HPLC negative samples, two were positive (2.94%) and 66 (97.06%) negative to the colorimetric method. The relative frequency of positive samples was 32%, HPLC had the highest mean serum levels (14.37%), followed by the colorimetric method (5.28%) and acid ninhydrin (3.12%). The high-performance liquid chromatography method was different from the acid and colorimetric ninhydrin methods. The ninhydrin and colorimetric methods were not different from each other, both of which could be used as screening methodologies. Among the three techniques, HPLC was the most sensitive methodology for the detection and quantification of serum in refrigerated raw milk.(AU)

Determinação do caseinomacropeptídeo em leite UAT por espectroscopia no infravermelho próximo e regressão por mínimos quadrados parciais / Determination of caseinomacropeptide in uht milk using near infrared spectroscopy and pls regression

O presente trabalho foi realizado com o objetivo de desenvolver um método para a determinação de CMP em leite UAT por meio da aplicação da espectroscopia de infravermelho próximo. Leites UAT de oito marcas diferentes foram utilizados para a construção dos modelos de calibração. Os resultados demonstram que, para o desenvolvimento de um modelo de calibração adequado para a determinação de CMP em leite UAT, deve-se utilizar, juntamente com o método de regressão PLS, o método de seleção de espectros máxima distância e os pré-tratamentos 2ª derivada e variável normal padronizada. Além disso, pôde-se determinar que as regiões do infravermelho próximo mais correlacionadas com os movimentos vibracionais dos aminoácidos presentes no CMP foram: 1100-1310; 1400-1430; 1490-1550; 1640-1680; 1780-1970; 2020-2100 e 2310-2350nm. Conclui-se que a espectroscopia de infravermelho próximo pode ser uma alternativa para a determinação de CMP em leite UAT, desde que haja um conjunto de calibração com amostras representativas da população a ser predita no futuro.(AU)

his work´s objective was to develop an UHT milk caseinomacropeptide determination method trough NIR spectroscopy application. Eight UHT milk trademarks are used to produce a mathematical calibration model. The results of NIR analysis suggested that to produce a suitable calibration model, partial least-square regression (PLSR) must be used, with maximum distance in wavelenght space to select spectra, pre - treatment with 2nd derivative and standard normal variant (SNV). Also, suitable near-infrared regions more correlated with CPM aminoacids vibrational movements: 1100-1310; 1400-1430; 1490-1550; 1640-1680; 1780-1970; 2020-2100; and 2310-2350nm. Therefore, NIR spectroscopy can be an alternative to caseinomacropeptide determination of UHT milk, since there was a representative calibration set with a large enough and representative sample of entire population to be predicted in the future.(AU)

Differentiating Tumor Progression from Pseudoprogression in Patients with Glioblastomas Using Diffusion Tensor Imaging and Dynamic Susceptibility Contrast MRI.

BACKGROUND AND PURPOSE: Early assessment of treatment response is critical in patients with glioblastomas. A combination of DTI and DSC perfusion imaging parameters was evaluated to distinguish glioblastomas with true progression from mixed response and pseudoprogression. MATERIALS AND METHODS: Forty-one patients with glioblastomas exhibiting enhancing lesions within 6 months after completion of chemoradiation therapy were retrospectively studied. All patients underwent surgery after MR imaging and were histologically classified as having true progression (>75% tumor), mixed response (25%-75% tumor), or pseudoprogression (<25% tumor). Mean diffusivity, fractional anisotropy, linear anisotropy coefficient, planar anisotropy coefficient, spheric anisotropy coefficient, and maximum relative cerebral blood volume values were measured from the enhancing tissue. A multivariate logistic regression analysis was used to determine the best model for classification of true progression from mixed response or pseudoprogression. RESULTS: Significantly elevated maximum relative cerebral blood volume, fractional anisotropy, linear anisotropy coefficient, and planar anisotropy coefficient and decreased spheric anisotropy coefficient were observed in true progression compared with pseudoprogression (P < .05). There were also significant differences in maximum relative cerebral blood volume, fractional anisotropy, planar anisotropy coefficient, and spheric anisotropy coefficient measurements between mixed response and true progression groups. The best model to distinguish true progression from non-true progression (pseudoprogression and mixed) consisted of fractional anisotropy, linear anisotropy coefficient, and maximum relative cerebral blood volume, resulting in an area under the curve of 0.905. This model also differentiated true progression from mixed response with an area under the curve of 0.901. A combination of fractional anisotropy and maximum relative cerebral blood volume differentiated pseudoprogression from nonpseudoprogression (true progression and mixed) with an area under the curve of 0.807. CONCLUSIONS: DTI and DSC perfusion imaging can improve accuracy in assessing treatment response and may aid in individualized treatment of patients with glioblastomas.

Obesity and glycemic control in patients with diabetes mellitus: Analysis of physician electronic health records in the US from 2009-2011.

AIMS: Examine the association between obesity and glycemic control among patients with type 1 (T1DM) or type 2 diabetes mellitus (T2DM). METHODS: Data from US physician electronic health records (Humedica®) from 2009-2011 were utilized. Patients were defined as having above-target glycemic control if they had an HbA1c ≥7% at any time during the study period. Multinomial logistic regressions were conducted separately for T1DM and T2DM patients, and examined associations between BMI categories and probability of having above-target glycemic control (≥7% and <8%, ≥8% and <9%, or ≥9%) while controlling for patient demographics, general health, comorbid conditions, and antihyperglycemic medication use. RESULTS: There were 14,028 T1DM and 248,567 T2DM patients; 47.8% of T1DM and 63.4% of T2DM were obese (BMI ≥30kg/m(2)). For T1DM, being overweight (BMI 25-<30), obese class I (30-<35), II (35-<40), or III (≥40) was associated with a significantly higher probability of having HbA1c≥8% and <9% or ≥9%, while being overweight was associated with a significantly higher probability of having HbA1c ≥7% and <8% compared to normal BMI (BMI≥18.5 and<25). For T2DM patients, being overweight, obese class I, II, or III was associated with a significantly higher probability of having HbA1c ≥7% and <8%, ≥8% and <9%, or ≥9%. CONCLUSIONS: For both T1DM and T2DM patients, there were positive and statistically significant associations between being overweight or obese and having suboptimal glycemic control. These findings quantify the associations between obesity and glycemic control, and highlight the potential importance of individual characteristics on glycemic control.

Efeito da contagem de células somáticas sobre o rendimento e a composição físico-química do queijo muçarela / The effect of somatic cell count on yield and physico-chemical composition of Mozzarella cheese

Determinou-se o efeito da contagem de células somáticas do leite sobre o rendimento e a composição físico-química do queijo muçarela. Foram selecionadas vacas com contagem de células somáticas (CCS) <200.000 células/mL; CCS >200.000 a <400.000 células/mL; CCS >400.000 células/mL a <750.000 células/mL e CCS >750.000 células/mL e que não receberam tratamento com antimicrobianos nos dias que antecederam a obtenção do leite utilizado no processamento. Os queijos foram avaliados por meio das análises de pH, acidez, umidade, proteína, gordura, extrato seco total e desengordurado. Os queijos elaborados do leite com alta CCS >750.000 cél./mL apresentaram menor teor de proteína, maior umidade e menor rendimento industrial. Conclui-se que a elevação da CCS cursou com alterações na qualidade do queijo muçarela, o que reflete em sua composição nutricional e microbiológica, pois ocorre um incremento na atividade de água, fator intrínseco indispensável para o crescimento microbiano e consequente redução da vida de prateleira...

The effect of somatic cell count (SCC) on the yield and composition of mozzarella cheese was evaluated. Cows with different levels of SCC in their milk (<200.000 cells/mL; >200.000 to <400.000 cells/mL; >400.000 cells/mL to <750.000 cells/mL and >750.000 cells/mL) were selected. The animals had no antimicrobial treatment prior to or on milk sampling day. The mozzarella cheese quality was evaluated analyzing pH, acidity, moisture and protein content, fat, total solids and nonfat solids. The trial was replicated four times and the experimental design was analyzed through randomized blocks. The mozzarella cheese from milk with high SCC (>750.000 cells/mL) had lower protein content, higher moisture content and lower industrial yield, compared to cheese from milk with lower levels of SCC. High numbers of SCC impaired mozzarella cheese quality, which was reflected in its nutritional and microbiological composition. We observed an increase in water activity, an intrinsic and essential factor for microbial growth...

White fish reduces cardiovascular risk factors in patients with metabolic syndrome: the WISH-CARE study, a multicenter randomized clinical trial.

BACKGROUND AND AIMS: Reduction of cardiovascular risk with high consumption of fish in diet is still a matter of debate, and concerns about heavy metal contamination have limited consumption of oily fish. We aimed to evaluate the effect of regular ingestion of white fish on cardiovascular risk factors in patients with metabolic syndrome. METHODS AND RESULTS: Multicenter randomized crossover clinical trial including 273 individuals with metabolic syndrome. An 8-week only-one dietary intervention: 100 g/d of white fish (Namibia hake) with advice on a healthy diet, compared with no fish or seafood with advice on a healthy diet. Outcomes were lipid profile, individual components of the metabolic syndrome, serum insulin concentrations, homeostasis model of insulin resistance, serum C-reactive protein and serum fatty acid levels. We found a significant lowering effect of the intervention with white fish on waist circumference (P < 0.001) and diastolic blood pressure (P = 0.014). A significant lowering effect was also shown after the dietary intervention with fish on serum LDL concentrations (P = 0.048), whereas no significant effects were found on serum HDL or triglyceride concentrations. A significant rise (P < 0.001) in serum EPA and DHA fatty acids was observed following white fish consumption. Overall adherence to the intervention was good and no adverse events were found. CONCLUSION: In individuals with metabolic syndrome, regular consumption of hake reduces LDL cholesterol concentrations, waist circumference and blood pressure components of the metabolic syndrome. CLINICAL TRIAL REGISTRY: White Fish for Cardiovascular Risk Factors in Patients with Metabolic Syndrome Study, Registered under ClinicalTrials.gov Identifier: NCT01758601.

Growth hormone treatment for sustained pain reduction and improvement in quality of life in severe fibromyalgia.

Functional defects in growth hormone (GH) secretion and its efficacy as a complementary treatment have been suggested for fibromyalgia. This study investigated the efficacy and safety of low-dose GH as an add-on therapy in patients with both severe FM and low insulin-like growth factor 1 levels. A total of 120 patients were enrolled in a multicenter, placebo-controlled study for 18 months. They were randomly assigned to receive either 0.006 mg/kg/day of GH subcutaneously (group A, n=60) or placebo (group B, n=60) for 6 months (blind phase). The placebo arm was switched to GH treatment from month 6 to month 12 (open phase), and a follow-up period after GH discontinuation was performed until month 18. Standard treatment for fibromyalgia (selective serotonin re-uptake inhibitors, opioids, and amitriptyline) was maintained throughout the study. Number and intensity of tender points, Fibromyalgia Impact Questionnaire (FIQ) with its subscales, and EuroQol 5 dimensions test (EQ5D) with visual analogue scale (VAS) were assessed at different time points. At the end of the study, 53% of group A patients obtained fewer than 11 positive tender points, vs 33% of group B patients (P<.05). 39.1% vs 22.4% reached more than 50% improvement in VAS (P<.05). Group A patients showed significantly improved FIQ scores (P=.01) compared with group B. Although GH discontinuation worsened all scores in both groups during follow-up, impairment in pain perception was less pronounced in the GH-treated group (P=.05). In this largest and longest placebo-controlled trial performed in FM (NCT00933686), addition of GH to the standard treatment is effective in reducing pain, showing sustained action over time.
