Temperature effects explain continental scale distribution of cyanobacterial toxins

2018

Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). Increasing attention is given to other classes, such as neurotoxins (e.g., anatoxin-a) and cytotoxins (e.g., cylindrospermopsin) due to their potency. Most studies examine the relationship between individual toxin variants and environmental factors, such as nutrients, temperature and light. In summer 2015, we collected samples across Europe to investigate the effect of nutrient and temperature gradients on the variability of toxin production at a continental scale. Direct and indirect…

Efficiency of acetic acid and formic acid as a catalyst in catalytical and mechanocatalytical pretreatment of barley straw

2016

In this study, the potential of organic acids (formic acid, acetic acid) in a catalytical and mechanocatalytic conversion of lignocellulosic barley straw to valuable sugars is explored using sulfuric acid as a reference. Acid-catalyzed hydrolysis has been carried out with acid-impregnated samples as well as unmodified barley straw. In the mechanocatalytical approach, pretreatment consists of impregnation with the acid catalyst and mechanical treatment by ball milling following chemical hydrolysis. Straw samples and residues were analyzed by Fourier transform infrared spectrometry (FT-IR) whereas hydrolysate analysis was based on total reducing sugar (TRS) determination following the DNS met…

Stem cell populations in the heart and the role of Isl1 positive cells

2013

Cardiac progenitor cells are multipotent stem cells isolated from both embryonic and adult hearts in several species and are able to differentiate at least into smooth muscle cells, endothelial cells and cardiomyocytes. The embryonic origin of these cells has not yet been demonstrated, but it has been suggested that these cells may derive from the first and secondary heart fields and from the neural crest. In the last decade, two diffe-rent populations of cardiac progenitor or stem cells have been identified and isolated, i.e., the Islet1 positive (Isl1+) and c-Kit positive (c-Kit+)/Stem Cell Antigen-1 positive (Sca-1+) cells. Until 2012, these two populations have been considered two separ…

Rimbaud e Apollinaire nas recreacións poéticas bielorrusas: particularidades do tratamento fraseoestilístico / Rimbaud and Apollinaire in Belarusian …

2021

Certas peculiaridades da linguaxe dos textos artísticos son difíciles de transmitir na tradución, aínda que se trate das características dominantes do estilo dun poeta. Isto é especialmente certo cando nos enfrontamos a estilos tan innovadores dende o punto de vista lingüístico como os de Rimbaud ou Apollinaire. Ao traducir os seus textos ao idioma bielorruso, o tradutor leva a cabo simultaneamente dúas tarefas: a de tradución propiamente dita e a de afirmar e actualizar o seu propio idioma. Neste artigo, ofrecemos unha análise comparativa dalgunhas características da combinatoria léxica da poesía de Rimbaud e de Apollinaire e as súas traducións ao bielorruso. Como metodoloxía de análise li…

The Exorbital Lacrimal Gland Is 100 Times More Susceptible Than the Retina to Dietary Supplies in Long Chain Omega-6 and Omega 3 Polyunsaturated Fatt…

2007

International audience; Purpose:: The purpose of this study was to compare the susceptibility of the retina and the exorbital lacrimal gland to dietary supplies in long chain omega-3 (ω3) and omega-6 (ω6) polyunsaturated fatty acids (LC-PUFAs). Methods:: Male Wistar rats were fed for 3 months with a 5% lipid-diet containing either: 1) 10% of EicosaPentaenoic Acid (EPA, ω3) and 7% of DocosaHexaenoic Acid (DHA, ω3), 2) 10% of γ-Linolenic Acid (GLA, ω6), 3) 10% of EPA, 7% of DHA and 10% of GLA or 4) a balanced diet deprived from EPA, DHA and GLA. After three months of feeding, lipids were extracted from the retina and the exorbital lacrimal gland and fatty acid composition was determined by ga…

CLA, “new nutrients”?

2005

International audience; Conjugated linoleic acid (CLA) refers to a class of positional and geometric dienoic isomers of linoleic acid. Chronic dietary supplementation with commercial isomeric mixtures sold as dietary supplements leads to a drop in fat mass in various species. The t10,c12-CLA isomer is responsible for this antiobesity effect.The reduction of fat mass is especially dramatic in the mouse, in which it is associated with a severe hyperinsulinemia, an insulin resistance and a massive liver steatosis. The origin of these adverse side effects and the putative chronology of events leading to CLA-mediated lipoatrophic syndrome are presented and discussed in this review. In Human, the…
