Raman microspectroscopy reveals unsaturation heterogeneity at the lipid droplet level and validates an in vitro model of bone marrow adipocyte subtypes

Olaia Maria Naveiras Torres-Quiroga, Josefine Catharina Pedersen Tratwal, Vasco Ledebur de Antas de Campos, Daniel Naveed Tavakol, Charles Christopher Bataclan

Bone marrow adipocytes (BMAds) constitute the most abundant stromal component of adult human bone marrow. Two subtypes of BMAds have been described, the more labile regulated adipocytes (rBMAds) and the more stable constitutive adipocytes (cBMAds), which d ...

Preferential retention of algal carbon in benthic invertebrates: Stable isotope and fatty acid evidence from an outdoor flume experiment

Tom Ian Battin

According to the River Continuum Concept, headwater streams are richer in allochthonous (e.g. terrestrial leaves) than autochthonous (e.g. algae) sources of organic matter for consumers. However, compared to algae, leaf litter is of lower food quality, par ...

A cellulolytic fungal biofilm enhances the consolidated bioconversion of cellulose to short chain fatty acids by the rumen microbiome

Robert Lawrence Shahab

The ability of the multispecies biofilm membrane reactors (MBM reactors) to provide distinguished niches for aerobic and anaerobic microbes at the same time was used for the investigation of the consolidated bioprocessing of cellulose to short chain fatty ...

From isonitrile to nitrile via ketenimine intermediate: Palladium-catalyzed 1,1-carbocyanation of ally carbonate by alpha-isocyanoacetate

David Savary, Qian Wang, Jieping Zhu, Guanyinsheng Qiu, Sheng-Cai Zheng

A palladium-catalyzed 1,1-carbocyanation of allyl carbonate by alpha-quaternary alpha-isocyanoacetate was developed. Formation of ketenimine followed by homolysis of the C-N bond and recombination of the resulting caged radical pair was proposed to account ...

Low-rank tensor methods for large Markov chains and forward feature selection methods

Francisco Santos Paredes Quartin de Macedo

In the first part of this thesis, we present and compare several approaches for the determination of the steady-state of large-scale Markov chains with an underlying low-rank tensor structure. Such structure is, in our context of interest, associated with ...

Sexual dimorphism in hepatic lipids is associated with the evolution of metabolic status in mice

Rolf Gruetter, Ana Francisca Leal Silva Soares, Hongxia Lei, Marc Moniatte, Jonathan Paz Montoya

Ectopic lipid accumulation in the liver is implicated in metabolic disease in an age- and sex-dependent manner. The role of hepatic lipids has been well established within the scope of metabolic insults in mice, but has been insufficiently characterized un ...

Innovative and stable TiO2 supported catalytic surfaces removing aldehydes under UV-light irradiation

Juan Kiwi, Sami Rtimi

The present study reports the photocatalytic degradation of aldehydes using TiO2 impregnated polyester (PES) and glass fiber (GFT)-TiO2 addressing the photocatalytic degradation aldehydes (air-solid interface). The PES-TiO2 optical absorption was determine ...

Dysregulation of soluble epoxide hydrolase and lipidomic profiles in anorexia nervosa

Pierre Magistretti, Jiangyan Yang

Individuals with anorexia nervosa (AN) restrict eating and become emaciated. They tend to have an aversion to foods rich in fat. Because epoxide hydrolase 2 (EPHX2) was identified as a novel AN susceptibility gene, and because its protein product, soluble ...

Pointwise estimates and existence of solutions of porous medium and p-Laplace evolution equations with absorption and measure data

Quoc Hung Nguyen

Let Omega be a bounded domain of R-N (N >= 2). We obtain a necessary and a sufficient condition, expressed in terms of capacities, for the existence of a solution to the porous medium equation with absorption {u(t) - Delta (vertical bar u vertical bar(m-1) ...

Orlicz regularity of the gradient of solutions to quasilinear elliptic equations in the plane

Linda Maria De Cave

Given a planar domain Omega, we study the Dirichlet problem {-divA(x, del v) = f in Omega, v = 0 on partial derivative Omega, where the higher-order term is a quasilinear elliptic operator, and f belongs to the Zygmund space L(log L)delta(log log log L)(be ...

On unique solvability of the full three-dimensional Ericksen-Leslie system

Tudor Ratiu

In this paper, we study the full three-dimensional Ericksen-Leslie system of equations for the nematodynamics of liquid crystals. We announce the short-time existence and uniqueness of strong solutions for the initial value problem in the periodic case and ...

Determination of the structure of the O-antigen and the lipid A from the entomopathogenic bacterium Pseudomonas entomophila lipopolysaccharide along with its immunological properties

Bruno Lemaitre

The structure and the immunology of the lipopolysaccharide (LPS) of Pseudomonas entomophila, an entomopathogenic bacterium isolated from the fruit fly Drosophila melanogaster, was characterized. The O-antigen portion was established and resulted to be buil ...

Optimal transport of closed differential forms for convex costs

Bernard Dacorogna, Olivier Kneuss

Let c : A(k-1) -> R+ be convex and Omega subset of R-n be a bounded domain. Let f(0) and f(1) be two closed k-forms on Omega satisfying appropriate boundary conditions. We discuss the minimization of integral(Omega) c (A) dx over a subset of (k - 1)-forms ...
