Design methodology for submerged anaerobic membrane bioreactors (AnMBR): A case study
2015
[EN] The main objective of this study is to propose guidelines for designing submerged anaerobic MBR (AnMBR) technology for municipal wastewater treatment. The design methodology was devised on the basis of simulation and experimental results from an AnMBR plant featuring industrial-scale hollow-fibre membranes. The proposed methodology aims to minimise both capital expenditure and operating expenses, and the key parameters considered were: hydraulic retention time, solids retention time, mixed liquor suspended solids concentration in the membrane tank, 20 C-standardised critical flux, specificgas demand per square metre of membrane area, and flow of sludge being recycled from the membrane …
Meox2/Tcf15 Heterodimers Program the Heart Capillary Endothelium for Cardiac Fatty Acid Uptake
2015
Background— Microvascular endothelium in different organs is specialized to fulfill the particular needs of parenchymal cells. However, specific information about heart capillary endothelial cells (ECs) is lacking. Methods and Results— Using microarray profiling on freshly isolated ECs from heart, brain, and liver, we revealed a genetic signature for microvascular heart ECs and identified Meox2/Tcf15 heterodimers as novel transcriptional determinants. This signature was largely shared with skeletal muscle and adipose tissue endothelium and was enriched in genes encoding fatty acid (FA) transport–related proteins. Using gain- and loss-of-function approaches, we showed that Meox2/Tcf15 media…
Upregulation of liver VLDL receptor and FAT/CD36 expressions in LDLR-/- apoB100/100 mice fed trans-10,cis-12 conjugated linoleic acid
2006
International audience; This study explores the mechanisms responsible for the fatty liver setup in mice fed trans-10,cis-12 conjugated linoleic acid (t10c12 CLA), hypothesizing that an induction of low density lipoprotein receptor (LDLR) expression is associated with lipid accumulation. To this end, the effects of t10c12 CLA treatment on lipid parameters, serum lipoproteins, and expression of liver lipid receptors were measured in LDLR(-/-) apoB(100/100) mice as a model of human familial hypercholesterolemia itself depleted of LDLR. Mice were fed t10c12 CLA over 2 or 4 weeks. We first observed that the treatment induced liver steatosis, even in the absence of LDLR. Mice treated for 2 weeks…
Expression of Putative Fatty Acid Transporter Genes Are Regulated by Peroxisome Proliferator-activated Receptor α and γ Activators in a Tissue- and I…
1998
Regulation of gene expression of three putative long-chain fatty acid transport proteins, fatty acid translocase (FAT), mitochondrial aspartate aminotransferase (mAspAT), and fatty acid transport protein (FATP), by drugs that activate peroxisome proliferator-activated receptor (PPAR) alpha and gamma were studied using normal and obese mice and rat hepatoma cells. FAT mRNA was induced in liver and intestine of normal mice and in hepatoma cells to various extents only by PPARalpha-activating drugs. FATP mRNA was similarly induced in liver, but to a lesser extent in intestine. The induction time course in the liver was slower for FAT and FATP mRNA than that of an mRNA encoding a peroxisomal en…
Serum pancreatic enzymes in human immunodeficiency virus-infected children - A collaborative study of the Italian Society of Pediatric Gastroenterolo…
1998
Numerous studies have shown pancreatic disease in adult human immunodeficiency virus (HIV)-infected patients, but there are very few reports on pediatric patients. Our aim was to determine the prevalence of increased serum pancreatic enzyme levels and their relationship to clinical manifestations of acute pancreatitis in HIV-infected children.Forty-seven consecutive, symptomatic HIV-infected children (24 male; median age, 7.3 years; range, 1-17 years) and 45 sex- and age-matched controls without gastroenterologic disease were enrolled. In all subjects serum total amylase, pancreatic amylase, and lipase were assayed with commercial kits. The following were recorded: disease progression (CDC …
Spectral function for overoccupied gluodynamics from real-time lattice simulations
2018
We study the spectral properties of a highly occupied non-Abelian non-equilibrium plasma appearing ubiquitously in weak coupling descriptions of QCD matter. The spectral function of this far-from-equilibrium plasma is measured by employing linear response theory in classical-statistical real-time lattice Yang-Mills simulations. We establish the existence of transversely and longitudinally polarized quasiparticles and obtain their dispersion relations, effective mass, plasmon frequency, damping rate and further structures in the spectral and statistical functions. Our new method can be interpreted as a non-perturbative generalization of hard thermal loop (HTL) effective theory. We see indica…
Estimation of the degrading genetic potential of soil bacterial communities: a new tool for evaluating and predicting soil contamination by organic m…
2007
During the last two centuries, industrialisation has led to increasing contamination of the environment by xenobiotics, notably aromatic compounds (i.e. PAHs, pesticides). These widespread pollutants are a major threat affecting soil quality and human health. In this context, numerous policies have been drawn up notably in Europe, to monitor the threats of pollution to ecosystems and to detect and implement measures to counterbalance the damage. Nevertheless, the European Commission and scientific community are still confronted with a lack of appropriate tools to monitor biodiversity in relation to environmental processes affecting global warming and soil protection. This study proposes too…
UN SIT PER IL PPE DEL CENTRO STORICO DI PALERMO: IL CASO STUDIO DEL MANDAMENTO CASTELLAMMARE
2015
In this work a Geographic Information System was realised at the service of municipal administration of Palermo, to integrate, manage and store city plan information regarding the urban district Castellammare whereof detailed executive plan of inner city, correlating basic cartography, current urban instrument, cadastral cartography, current restriction schemes, monumental and historical monuments, street numbers and street network. Quantum GIS vers. 1.8 of Free and Open-Source Software (FOSS) community was exclusively utilized to the fulfilment of GIS. To the experimentation and the fulfilment of WebGIS a free server was used in cloud on the Amazon, where a virtual machine, based on MapSer…
Analysis of Profiles of Family Educational Situations during COVID-19 Lockdown in the Valencian Community (Spain)
2022
Due to the pandemic (COVID-19), the education system in Spain was forced to close for three months, creating an unprecedented situation: improvised distance schooling. Family characteristics and their life situations with Information and Communication Technology use would be aspects to be studied as educational conditioning factors. This paper presents the ways in which a representative sample of families in the Valencian Community (Spain) assumed the education of their children during the lockdown. Mixed methods (quantitative -surveys-/qualitative -focus groups-) are used. Multivariate profiles are studied (k-means cluster) that summarise the life circumstances, represented by composite in…
Búsqueda de nuevos ingredientes bioactivos en obesidad para el diseño de nuevos alimentos funcionales, en base a la demanda del consumidor
2015
La innovación tecnológica en materia de salud ha sido un campo ampliamente estudiado y sigue siendo un foco de interés económico reiterado y prioritario. La alimentación es uno de los hábitos que más repercusión tienen en el estado de salud y en la prevención de determinadas enfermedades lo que influye cada vez más en los hábitos de compra de los consumidores (Niva M., 2007, Bech-Larsen T et al., 2007, Jones PJ et al., 2007, Van Kleef E et al., 2002). Un trastorno de la alimentación puede generar obesidad y con ello el desarrollo de múltiples complicaciones asociadas a la misma. En los últimos años, la Organización Mundial de la Salud (WHO., 2014 y 2015) ha venido alertando de la gran crisi…
