Activation of a caspase-3-independent mode of cell death associated with lysosomal destabilization in cultured human retinal pigment epithelial cells…
2008
International audience; Purpose: To characterize the possible cytotoxic effects of oxysterols (7-hydroxycholesterol (7-OH), 25-hydroxycholesterol (25-OH)) in human retinal pigment epithelial cells (ARPE-19) and to detail the relationships between some of these effects. Methods: ARPE-19 cells were treated with 7-OH and 25-OH. Cell viability was measured with the MTT assay. Membrane permeability, mitochondrial potential, and lysosomal integrity were measured by flow cytometry with propidium iodide, DiOC6(3), and acridine orange, respectively. Cell death was characterized by staining with Hoechst 33342, transmission electron microscopy, and analysis of the DNA fragmentation pattern. Caspase ac…

THE REHABILITATION THROUGH EXTERNAL PRESTRESSING OF HISTORICAL REINFORCED CONCRETE BRIDGES WITH REDUCED PERFORMANCE: A CASE STUDY
2022
Many existing reinforced concrete bridges exhibit behaviour at the Service Limit State and the Ultimate Limit State which can be considered unsatisfactory with respect to the current provisions of Codes, but which are actually deficiencies deriving from obsolete calculation methods, structure age, material degradation, diffuse or localized corrosion and increased loads. Among these, cantilever bridges with half-joints may present a decrease in global safety coefficients for the most stressed current sections of the deck or in the local ones, that affect the performance of elements sensitive to degradation, such as Gerber saddles. In these cases, simple strengthening interventions through ex…
False-positive LSD testing in urine samples from intensive care patients.
1998
Unexpected positive results for lysergic acid diethylamide (LSD) were found in urine samples from 12 patients in an intensive care unit in a routine screening using the CEDIA DAU assay. None of these test results could be confirmed by high-performance liquid chromatography analysis, but all samples contained the mucolytic drug ambroxol. Further studies demonstrated that ambroxol exhibits a significant cross-reactivity in the CEDIA DAU LSD assay. Therefore, positive LSD results obtained with the CEDIA DAU assay have to be critically evaluated, particularly during the cold season, when infections of the respiratory tract often result in more frequent use of mucolytic medications.
Effect of Adding Resistant Maltodextrin to Pasteurized Orange Juice on Bioactive Compounds and Their Bioaccessibility
2021
Resistant maltodextrin (RMD) is a water-soluble and fermentable functional fiber. RMD is a satiating prebiotic, reducer of glucose and triglycerides in the blood, and promoter of good gut health, and its addition to food is increasingly frequent. Therefore, it is necessary to study its potential effects on intrinsic bioactive compounds of food and their bioaccessibility. The aim of this study was to evaluate the effect of adding RMD on the bioactive compounds of pasteurized orange juice with and without pulp, and the bioaccessibility of such compounds. RMD was added at different concentrations: 0 (control sample), 2.5%, 5%, and 7.5%. Ascorbic acid (AA) and vitamin C were analyzed using HPLC…
Impact of Resistant Maltodextrin Addition on the Physico-Chemical Properties in Pasteurised Orange Juice
2020
Resistant maltodextrin (RMD) is a water-soluble fibre that can be fermented in the colon and exert prebiotic effects. Therefore, its addition to food and beverage products could be beneficial from both technological and nutritional viewpoints. However, to date, most studies have focused on the stability of the prebiotic fibre rather than its impact in the original food matrices. Therefore, this work aimed to evaluate the addition of RMD on the physico-chemical properties of pasteurised orange juice (with and without pulp). °
Characterisation of the volatile fraction of aromatic caramel using heart-cutting multidimensional gas chromatography
2014
The first aim of our study was to improve characterisation of the volatile fraction of aromatic caramel by applying heart-cutting multidimensional gas chromatography coupled to mass spectrometry and olfactometry (MDGC-MS-O) on targeted odorant fractions. The second aim was to compare the volatile composition of two caramel samples, which differed in terms of their carbohydrate composition and cooking process. MDGC analyses enabled identification of 37 compounds (17 with the addition of pure standard) in the burnt sugar caramel, 20 of which were reported for the first time in caramel. Fifteen compounds were identified as odour-active and described using a range of attributes such as floral, …
Voix hors champ: Stendhal historien de l'art contemporain dans l'Histoire de la peinture en Italie (1817)
2012
This article investigates Stendhal's ideas on contemporary French art as they shine through his «Histoire de la peinture en Italie» (1817) and the novel «La chartreuse de Parme» (1839).
Hidro-hegemonija Oranžas-Senķu upes baseinā: Dienvidāfrikas lomas analīze
2019
Hidro-hegemonija Oranžas-Senķu upes baseinā: Dienvidāfrikas lomas analīze - gadījuma analīze, kurā tiek pētīta pārrobežu ūdens resursu apsaimniekošana starp Dienvidāfriku, Lesoto, Namībiju un Botsvānu. Darbā tiek pieņemts, ka Dienvidāfrika ir reģionālais hidro-hegemons konkrētajā baseinā. Dienvidāfrika nav augšupteces valsts, bet tai piemīt pietiekoši daudz varas pār augšupteces valsti Lesoto. Pētījuma mērķis - pielāgot hidro-hegemonijas analītisko ietvaru konkrētajam baseinam, lai noteiktu, kāda hidro-hegemonijas forma pastāv Oranžas-Senķu upes baseinā, un atklātu iemeslus, kādēļ Dienvidāfrika ir izvēlējusies spēlēt līdera lomu konkrētajā upes baseinā. Lai sasniegtu mērķi, tika noteikti šā…
