Mechanical circulatory and/or respiratory assistance with extracorporeal membrane oxygenation (ECMO) has become a standard of care for patients with circulatory (venoarterial) and/or respiratory (venovenous) failure refractory to standard therapies. Adult patients with congenital heart disease are an increasingly recognized and growing population and include various groups, such as undiagnosed cases in childhood and palliated and/or corrected cases, which require subsequent care because of residual lesions, cardiac arrest/insufficiency, and arrhythmias, among other conditions. In addition, these patients are prone to developing pathologies that are typical of adulthood with a generally increased risk of morbidity and mortality because of their low reserves and organic damage associated with the underlying heart disease, which makes them candidates for ECMO. These patients represent an additional challenge in this therapy because malformations and the presence of a shunt can generally affect the usual cannulation methods and hemodynamic and oximetry monitoring. Thus, the configuration decision must be made on a case-by-case basis. Here, we present a cannulation method, venopulmonary artery ECMO, which provides hemodynamic and respiratory support, and may be ideal for patients with shunts and/or right ventricular dysfunction. To our knowledge, this is the first report of this configuration in patients with congenital heart diseases.

In this study, it is reported an analytical approach to recover organochlorine pesticides from a clay soil. Soil was physical and chemically characterized. Also pesticides extraction was carried out using packed columns and various aqueous media (H2O-milliQ, NaOH, HCl, SDS, Triton X-114, Humic acids and Acetonitrile). The leachate samples were analyzed on an Agilent Technologies 6890N Gas Chromatograph with electron capture in a# AB002 Column 30.0 m × 250 μm × 0.25 μm calibrated, 25 psi pressure, flow 2.9 ml/min, temperature 25°C, ultra-high purity Helium as the entrainment gas and an elution time of 50 min. The results show that the highest extraction percentage of pollutants in the soil washing was obtained with acetonitrile recovering: p, p’-DDT (91.0%);p, p’-DDE (92.0%);p, p’-DDD (96.0%);aldrin (98.6%);dieldrin (98.0%). With Triton X-114, the extractions recovery was: p, p’-DDT (63.0%);p, p’-DDE (64.0%);p, p’-DDD (65.0%);aldrin (67.0%);dieldrin (72.0%). This study illustrates the potential Applicability of SPME for routine analysis of organochlorine pesticides in soils.

Optic Neuritis in Acute Neuroborreliosis (Lyme Disease) in the U.S.-Mexican Border: Case Report

引用

World Journal of Neuroscience 2016年第2期6卷 126-130页

作者： Ihtesham A. Qureshi Michael F. Maldonado gustavo J. Rodriguez Salvador cruz-Flores Alberto Maud Neurology Department Texas Tech University Health Sciences Center El Paso USA Ophthalmology Department Texas Tech University Health Sciences Center El Paso USA

Objective: We describe a patient diagnosed with acute neuroborreliosis presenting with anterior optic neuritis (papillitis) in a non-endemic region. Case Presentation: A 43-year-old previously healthy right handed man admitted due to an insidious onset of severe headache and spells of ascending paresthesias from his right foot into his right arm and face followed by speech arrest and clumsiness of his right hand. His neurologic exam was significant for somnolence, nuchal rigidity and Kernig and Brudzinski signs were present. MRI of the brain with gadolinium showed diffuse hyperintense signal involving the supra and infratentorial cortical sulci, with associated faint diffuse leptomeningeal enhancement, consistent most likely with diffuse leptomeningoencephalitis. EEG: normal. CSF VDRL was negative. Dilated fundus exam revealed mild optic nerve edema more significant to the left than to the right eye, confirmed and measured by spectral domain OCT (Optical Coherence Tomography). There was an evidence of posterior uveitis with an early vitreous hemorrhage superficial to the left optic nerve. Lyme disease serum antibody (IgM) Immunoblotting was positive in 2 bands confirming the diagnosis of neuroborreliosis. Conclusion: Optic nerve involvement in Lyme disease is an uncommon complication that should be confirmed by specific diagnostic criteria to establish its causal relation.

AIM To study the differences in immune response and cytokine profile between acute liver failure and selflimited acute *** Forty-six patients with self-limited acute hepatitis(AH), sixteen patients with acute liver failure(ALF), and twenty-two healthy subjects were involved in this study. The inflammatory and anti-inflammatory products in plasma samples were quantified using commercial enzyme-linked immunoassays and quantitative real-time PCR. The cellular immune responses were measured by proliferation assay using flow cytometry. The groups were divided into viral- and non-viral-induced selflimited AH and ALF. Thus, we worked with five groups: Hepatitis A virus(HAV)-induced self-limited acute hepatitis(HAV-AH), HAV-induced ALF(HAV-ALF), nonviral-induced self-limited acute hepatitis(non-viral AH), non-viral-induced acute liver failure(non-viral ALF), and healthy subjects(HC). Comparisons among HAV and non-viral-induced AH and ALF were *** The levels of mitochondrial DNA(mt DNA) and the cytokines investigated [interleukin(IL)-6, IL-8, IL-10, interferon gamma, and tumor necrosis factor] were significantly increased in ALF patients, independently of etiology(P < 0.05). High plasma mt DNA and IL-10 were the best markers associated with ALF [mt DNA: OR = 320.5(95%CI: 14.42-7123.33), P < 0.0001; and IL-10: OR = 18.8(95%CI: 1.38-257.94), P = 0.028] and death [mt DNA: OR = 12.1(95%CI: 2.57-57.07), P = 0.002; and IL-10: OR = 8.01(95%CI: 1.26-50.97), P = 0.027]. In the cellular proliferation assay, NK^(bright), NKT and regulatory T cells(TReg) predominated in virusspecific stimulation in HAV-induced ALF patients with an anergic behavior in the cellular response to mitotic stimulation. Therefore, in non-viral-induced ALF, anergic behavior of activated T cells was not observed after mitotic stimulation, as expected and as described by the literature. CONCLUSION mt DNA and IL-10 may be predictors of ALF and death. TReg cells are involved in immunologi

Diversity of Filamentous Fungi of Area from Brazilian Caatinga and High-Level Tannase Production Using Mango (Mangifera indicaL.) and Surinam Cherry (Eugenia unifloraL.) Leaves under SSF

引用

Advances in Microbiology 2013年第8期3卷 52-60页

作者： Roberta cruz Juliana Silva de Lima Julyana Cordoville Fonseca Maria José dos Santos Fernandes Débora Maria Massa Lima gustavo Pereira Duda Keila Aparecida Moreira Cristina Maria de Souza Motta Academic Unit of Garanhuns Federal Rural University of Pernambuco Garanhuns Brazil Department of Mycology Federal University of Pernambuco Recife Brazil

Tannase is a biotechnologically important enzyme that can be produced during fungal fermentation of organic matter. The Caatinga is an exclusive Brazilian ecosystem that has been largely unexplored by science, particularly its filamentous fungal diversity. This study evaluated the diversity of filamentous fungi in the Caatinga soils of Pernambuco, Brazil, and their potential for tannase production by solid-state fermentation (SSF) of mango (Mangifera indica L.) and Surinam cherry (Eugenia uniflora L.) leaves. A total of 4711 isolates were obtained, 2090 during the rainy seasonand 2621 during the dry season. The isolates belonged to 18 genera and 66 species, with Aspergillus and Penicillium having the highest species richness. The dry season had a higher diversity index. Aspergillus was the dominant genus, and A. flavus, A. sclerotiorum, and A. ochraceus the most abundant species. A representative of each species was tested for tannase production using dried mango and Surinam cherry leaves as substrates;the leaves contained 14.28 and 7.0 g/L tannin, respectively. Most fungal species produced tannase, but the highest yields were obtained when mango leaves were used as substrate for Penicillium restrictum (accession URM 6044), Aspergillus flavofurcatus (URM 6142), and A. stromatoides (URM 6609), which produced 104.16, 87.51, and 81.83 U/mL tannase, respectively. These yields exceeded previously published reports. Filamentous fungi from Caatinga soils have great potential for producing tannase by SSF, and low-cost mango leaves make excellent substrate.

The effect of the application of ethanolic extract of “Haden” mango seeds to increase the antioxidant and antimicrobial capacity of fresh-cut mango flesh was evaluated. Phenolic HPLC analysis revealed that gallic acid was the major identified compound in the ethanolic extract (586.68 mg/g). Fresh-cut mango was treated for immersion within the ethanolic extract, packed and stored at 5℃ during 15 days. The content of phenolic compounds, antioxidant capacity and microbial growth of the treated mango were evaluated during the storage. Compared with the controls the treated fruit presented the highest content of the total phenolic (7.4 times), flavonoids (3.1 times), and antioxidant capacity DPPH·, TEAC and ORAC (2.9, 2.3 and 2.8 times, respectively), and showed a microbial reduction of 80% of mesophilic plate count and 97% of total molds. This study demonstrates the potential of phenolic compounds derived from mango seed as antimicrobials and antioxidants.

引用

Natural Science 2015年第7期7卷 370-378页

作者： Gisel Chenard Díaz Yordanka Reyes cruz René González Carliz Rosa C. Vitorino de Paula Donato A. Gomes Aranda Marcellus A. G. Dario gustavo Saraiva Marass Nelson C. Furtado Grand Valle Bio Energy Ltda.

At present, Brazil imports approximately 11 billion liters/year of diesel. With the interruption of the works in the new Petrobras refineries, the projection is that by 2025 this volume will increase to 24.2 billion liters of diesel/year. In this sense, the biodiesel factory Grand Valle Bio Energy Ltda., located in the state of Rio de Janeiro, in conjunction with the FAPERJ makes some investments in technology development for the cultivation and use of microalgae as an alternative raw material in the production of biodiesel. Based on arguments previously said, this work presents the results of the microalgae cultivation Monoraphidium sp. in photobioreactors the pilot plant of the company. The installation with an area of 120 m2 is included with 2 open photobioreactors of type falling film (20 m × 1 m), with a cascade of 18mm and capacity of 4000 L. The lineage cultivated is selected from previous ecophysiological studies that are identified as promising for biodiesel production by having a high potential for the production of lipids. This lineage is maintained at collection of the stock of cultures Laboratory of Green Technologies of the School of Chemistry/ UFRJ. The cultivation was performed in means ASM-1 (Gorham et al., 1964), initial pH 8.0, with aeration and circulation average of 8 hours a day during 19 days. The culture was started with an inoculum of 1 × 107 cel/ml. The lipid production was determined in two phases of growth: on day 4 (exponential phase) and 15 day (stationary phase). For the determination and quantification of lipid content, two different methods were assessed for a sample of biomass, submitted to the same processes the separation and drying. The results showed the methodology of Bligh & Dyer with modifications as the most efficient in extracting lipids. The total lipid content of the biomass Monoraphidium sp. was 30.58%. The growth rate varied between 0.74 ± 0.01 and 0.68 ± 0.02.
