Evidence in the formation of conjugated linoleic acids from thermally induced 9t12t linoleic acid: a study by gas chromatography and infrared spectro…
2009
Accepted version of article published in the journal: Chemistry and Physics of Lipids. Published version available on Science Direct: http://dx.doi.org/10.1016/j.chemphyslip.2009.07.002 Thermally induced isomerisation leading to the formation of conjugated linoleic acids (CLAs) has been observed for the first time during the thermal treatment of 9t12t fatty acid triacylglycerol, and methyl ester. Fifteen microlitre portions of the triacylglycerol sample containing 9t12t fatty acid (trilinoelaidin) were placed in micro glass ampoules and sealed under nitrogen, then subjected to thermal treatment at 250 degrees C. The glass ampoules were removed at regular time intervals, cut open, and the co…
Phosphatidylinositol specific phospholipase C of plant stems : membrane associated activity concentrated in plasma membranes.
1987
A phosphatidylinositol-specific phospholipase C of plant stems (EC 3.1.4.10) assayed at pH 6.6 and at 30 degrees C cleaved phosphatidylinositol such that more than 85% of the product was inositol-1-phosphate. Other phospholipids were cleaved 5 to 10% or less under these conditions. The phospholipase had both a soluble and a membrane-associated form. The soluble activity accounted for approximately 85 to 90% of the activity and 15% was associated with membranes. The membrane-associated activity was most concentrated in the plasma membranes of hypocotyl segments of both soybean (Glycine max) and bushbean (Phaseolus vulgaris). The plasma membrane location was verified by analysis of highly pur…

Studies of Reversible Hydrogen Binding in Nano- Sized Materials
2015
Experimental review of materials suitable for reversible hydrogen binding in nanoporous and nanosized structures of materials, based on natural zeolite (clinoptilolite) and graphene (exfoliated electrochemically from raw graphite), were analyzed. Characterization of materials with SEM, XRD, EDS and Raman spectroscopy methods and aspects of synthesis of a nanostructured zeolite and a few-layer graphite material was done in this work. It was established from gas analyzer results that hydrogen mass fraction in natural zeolite ranged from 1.1 % to 1.4 %, but in the few-layer graphite material − from 0.39 % to 0.46 %.
Salsolinol and ethanol-derived excitation of dopamine mesolimbic neurons: new insights
2013
Evidence supporting the essential role of brain-derived ethanol metabolites in the excitation of dopamine (DA) midbrain neurons has multiplied in the last 10–15 years. The pioneer and influential behavioral studies by CM Aragon and colleagues (see Correa et al., 2012 for a complete review) and more recent data (Sanchez-Catalan et al., 2009; Marti-Prats et al., 2010, 2013) have repeatedly demonstrated the crucial role displayed by acetaldehyde (ACD) in the locomotor and other behavioral responses elicited by ethanol. Although these experiments mainly used an indirect measure (exploratory locomotion) as an index of the excitation of DA neurons in the ventral tegmental area (VTA), results stro…
La configuración del derecho de asilo en la Unión Europea a la luz renovadora del derecho a no sufrir tortura o tratos inhumanos y degradantes
2018
The Chapter analyzes the EU Court of Justice case law on Aliens' Protection Regimes in light of the EU Charter of Fundamental Rights and of the European Convention of Human Rights focusing on: a) the impact of non refoulement and protection from risk of torture and inhuman or degrading treatments principles; b) procedural safeguards of right to seek "asylum" on the implementation of EU "Dublin regulation". Both aspects are taken into exam in the perspective of identifying common EU standards of protection of fundamental rights of the persons in the process of judicial implementation of the EU Charter of Fundamental Rights lead by the European Union Court of Justice (expecially after the ent…
Planktonic foraminifera in ODP Hole 160-963A
2006
New faunal and floral records from Ocean Drilling Project Hole 963A, resolved at ?80-year spacing, provide evidence of suborbital scale climate variability in the central Mediterranean Sea throughout Marine Isotope Stage (MIS) 5. Cold events in the central Mediterranean Sea, indicated by low abundances of warm species and high abundances of cold species, are also evident in a planktonic foraminifera paleoclimatic curve. They have been linked to NGRIP Greenland ice core “C” events and appear correlative with similar sub-millennial climate fluctuations identified in the North Atlantic region and in the Alboran Basin (Westernmost Mediterranean). Low-resolution benthic and planktonic Oxygen Iso…
A influência do método de armazenamento na transparência do cristalino de porco
2019
Este artículo se ha publicado de forma definitiva en: http://www.scielo.br/pdf/abo/v82n1/0004-2749-abo-82-01-0056.pdf Purpose: The porcine eye is frequently used as a research model. This paper analyzes the effect of different storage methods on the transparency of pig crystalline lens. Methods: A spectral transmission curve (from 220 to 780 nm) for the crystalline lens was determined experimentally after storage in different conditions: saline solution, formalin, castor oil, and freezing at -80°C. The total transmission in the visible spectrum, which was used as an index of transparency, was calculated from these curves. For comparative purposes, fresh lenses were evaluated and used as con…
"Per via di levare". Scavare e sottrarre in architettura
2014
Scavare, dal latino excavare (ex-cavare), possiede etimologicamente il significato di “rendere cavo” mediante l’azione del subtrahĕre (sottrarre). Tuttavia il significato del termine all’interno della sua necessaria disambiguazione non può essere inteso limitatamente alla luce dell’etimologia latina. Si dirà allora che la tecnica dello scavo è opposta e complementare alla tecnica dell’accumulazione. È un procedere per sottrazione di volumi, un operare in negativo per asportazione di materiale, erodendo, cavando ed estraendo. Il saggio indaga, attraverso un intenso per quanto lacunoso excursus tra le esperienze della contemporaneità l'emergere del archetipico della dimensione ipogea dell’arc…
Roflumilast N-oxide reverses corticosteroid resistance in neutrophils from patients with chronic obstructive pulmonary disease
2013
Background Glucocorticoid functions are markedly impaired in patients with chronic obstructive pulmonary disease (COPD). The phosphodiesterase 4 inhibitor roflumilast N-oxide (RNO) is the active metabolite of roflumilast approved as a treatment to reduce the risk of exacerbations in patients with severe COPD. Objective We sought to characterize the differential effects of RNO versus corticosteroids and their potential additive/synergistic effect in neutrophils from patients with COPD, thus providing scientific rationale for the combination of roflumilast with corticosteroids in the clinic. Methods Peripheral blood neutrophils were isolated from patients with COPD (n = 32), smokers (n = 7), …
