INTRODUCTION: Encephalomyeloradiculopathy (EMR) is a new syndrome, characterized by extensive involvement of the nervous system at different levels, including brain, medulla and spinal roots. We describe a patient presenting with prodromal febrile illness, followed by a wide infection of the nervous system with transverse myelitis and less severe meningitis, encephalitis and polyradiculopathy. The patient was treated with high-dose corticosteroids, antibiotics and acyclovir; in spite of therapy his condition improved very slowly, with severe neurological sequelae. MATERIAL AND METHODS: Antiviral antibodies were searched for in serum and cerebrospinal fluid (CSF) by commercially available ELISA kits. Viral investigations were performed by cell culture isolation and search for viral antigens, and genomic nucleic acids were investigated by polymerase chain reaction (PCR). RESULTS: Virological and serological studies evidenced a primary infection by cytomegalovirus (CMV), possibly responsible for the prodromal illness, persisting in the course of the disease. PCR performed in the peripheral blood mononuclear cells (PBMCs), DNA collected early and in the CSF drawn 30 days after the onset of the disease showed Epstein-Barr virus (EBV) DNA. The serum panel of EBV antibodies was typical of an intercurrent virus reactivation, more than of a primary infection. CONCLUSION: EBV is known to be highly infectious for the nervous system, in this case of EMR the presence of DNA sequences in the PBMCs and CSF suggests that EBV plays a role in the development of this newly described syndrome. 相似文献

Iron and nickel nanowires are grown by the matrix synthesis technique in the pores of the track membrane fabricated based on polyethylene terephthalate (PET). Scanning electron microscopy (SEM) and atomic force microscopy (AFM) are used to image the pores on the surface of the specimens and determine the 3d metal nanowires in a polymer bulk. The magnetization curves of the arrays of the nanowires are obtained. Magnetic properties of the nanowires are studied by the magnetic force microscopy (MFM) methods. The influence of the interposition and magnetostatic interaction of the nanowires of the magnetic metals in the polymer membrane, as well as the magnitudes and orientation of the applied external magnetic field, on the obtained MFM images is shown. The simulation results of the MFM images are in good agreement with the experimental data. 相似文献

Biogas has limited use in energy generation mainly due to the presence of hydrogen sulfide (H2S). Currently, most of the techniques employed in the removal of H2S from biogas have a chemical base, with high material costs and generating secondary pollutants. Biological processes for H2S removal have become effective and economical alternative techniques to traditional gas-treatment systems based on physicochemical techniques. Therefore, the aim of this work was to investigate the performance of a bench-scale biofilter for the removal of H2S present in synthetic biogas. In addition, CO2 and CH4 concentrations in the outlet biogas were evaluated. The inoculum used in the experiment was composed of Acidithiobacillus thiooxidans fixed on a packing of wood chips. Synthetic biogas was supplied to the system with a composition of 60 % CH4, 39 % CO2 and 1 % H2S. The biofilter operated continuously for 37 days with an average H2S removal efficiency of 75 ± 13 % and maximum of 97 %. The elimination capacity of the system reached an average of 130 ± 23 g m?3 h?1 and a maximum of 169 g m3 h?1. The biofiltration system showed an average reduction of only 6 % in CH4 concentration from biogas. Thus, besides being efficient in the removal of H2S, the system was able to maintain the biogas energy value. 相似文献

Selenoprotein P, a selenium-transporter protein, has been hypothesized to play a role in the etiology of neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and Alzheimer’s dementia (AD). However, data in humans are scarce and largely confined to autoptic samples. In this case–control study, we determined selenoprotein P concentrations in both the cerebrospinal fluid (CSF) and the serum of 50 individuals diagnosed with ALS, 30 with AD, 54 with mild cognitive impairment (MCI) and of 30 controls, using sandwich enzyme-linked immunosorbent assay (ELISA) methods. We found a positive and generally linear association between CSF and serum selenoprotein P concentrations in all groups. CSF selenoprotein P and biomarkers of neurodegeneration were positively associated in AD, while for MCI, we found an inverted-U-shaped relation. CSF selenoprotein P concentrations were higher in AD and MCI than in ALS and controls, while in serum, the highest concentrations were found in MCI and ALS. Logistic and cubic spline regression analyses showed an inverse association between CSF selenoprotein P levels and ALS risk, and a positive association for AD risk, while an inverted-U-shaped relation with MCI risk emerged. Conversely, serum selenoprotein P concentrations were positively associated with risk of all conditions but only in their lower range. Overall, these findings indicate some abnormalities of selenoprotein P concentrations in both the central nervous system and blood associated with ALS and neurocognitive disorders, though in different directions. These alterations may reflect either phenomena of etiologic relevance or disease-induced alterations of nutritional and metabolic status. 相似文献
