Fatty Acids of Microbial Origin in the Perirenal Fat of Rats (Rattus norvegicus domestica) and Guinea Pigs (Cavia porcellus) Fed Various Diets.

2020

Guinea pigs are assumed to practice caecotrophy to a higher degree than rats. Studies from leporids suggest that through the practice of caecotrophy, hindgut fermenting species could build up microbial fatty acids (FA) in body tissues. We hypothesized that microbial FA would be detectable in the body tissue of guinea pigs and rats, and this to a higher degree in guinea pigs. Twenty-four rats and guinea pigs were fed with four different pelleted diets (lucerne-, meat-, meat-bone-, insect-based) in groups of six animals for 8 weeks. Perirenal adipose tissue differed in FA composition between the species in spite of the common diets. FA typically associated with microbial activity (saturated F…

Odorant Metabolism Analysis by an Automated Ex Vivo Headspace Gas-Chromatography Method

2015

International audience; In the olfactory epithelium (OE), odorant metabolizing enzymes have the dual function of volatile component detoxification and active clearance of odorants from the perireceptor environment to respectively maintain the integrity of the tissues and the sensitivity of the detection. Although emphasized by recent studies, this enzymatic mechanism is poorly documented in mammals. Thus, olfactory metabolism has been characterized mainly in vitro and for a limited number of odorants. The automated ex vivo headspace gas-chromatography method that was developed here was validated to account for odorant olfactory metabolism. This method easily permits the measurement of the f…

Ecrire l’histoire des émotions. De l’objet à la catégorie d’analyse

2013

L’histoire des emotions a connu depuis une dizaine d’annees un developpement spectaculaire, avec des resultats inegaux. Cet article s’efforce de rendre compte des principales directions dans lesquelles cette histoire s’est engagee, et d’en proposer un premier bilan critique. Cela suppose au prealable de mettre au jour les tensions, souvent implicites, auxquelles elle se heurte, engendrant de nombreux debats. Parmi ces tensions figurent les partages entre nature et culture, langage et experience, individuel et collectif. A partir d’une historiographie essentiellement dix-neuviemiste, l’article propose de faire de l’emotion non un objet clos, mais une categorie d’analyse transversale, un moye…

Spontaneous perirenal hematoma due to a small perihilar renal cell carcinoma.

1988

Spontaneous renal rupture is an infrequent event and is usually caused by a predisposing factor. Up to 178 cases have been published. We present a case of a large spontaneous perirenal hematoma caused by a perihilar renal cell carcinoma of a 1-cm diameter. Reviewing the literature, a classification of the condition is given according to the underlying pathology and mechanism of rupture. The need for explorative surgery in cases which cannot be clarified by noninvasive diagnostic tools is discussed.

Transcatheter embolization of a renal artery pseudoaneurysm after open partial nephrectomy.

2011

Twelve days after an open partial nephrectomy, a 31-year-old man was re-admitted urgently for acute lumbar pain. An emergent helical computed tomography scan with intravenous contrast revealed a 3-cm renal artery pseudoaneurysm at the site of the partial nephrectomy, which was responsible for a large perirenal hematoma. Transarterial hyperselective embolization successfully occluded the pseudoaneurysm with less than 1 mL of N-butyl-2-cyanoacrylate, an embolizing agent less costly than coils. The kidney parenchyma was fully preserved.

Inclusive Design for Alzheimer’s Disease: Low-cost Treatments, Design and ICT

2019

Inability to acquire new memories, difficulty to remember recent events and to recognize objects, places and people, visual-spatial disorientation, these are some of the disorders with which who is affected by neurological diseases must learn to live with. In a continuously evolving society, where the decreasing birth rate and the drops in mortality are consistent, the job of Architecture is precisely to interpret the requirements and needs of people who have lost the canonical relationship with the world and give them the possibility to recover it or maintain it through communication channels that use their remaining ability to understand. The indoors and outdoors acquire a “prosthesis fun…

'No speech at my command will fit the forms in my mind': Shaping the Spiritual through Writing and Typing in George MacDonald’s Lilith Manuscripts

2020

International audience; In “Lilith B” (1893), the most extensively rewritten draft of George MacDonald’s fantasy novel Lilith (1895), puzzling triangular-shaped insertions, some handwritten and some typed, although not retained in the later versions of the text, allow for a better understanding of the creative process and show how the material crafting of the manuscript, through collage and combination techniques, played a part in the invention of fantasy. The introduction of the typewriter as a new drafting tool in MacDonald’s writing habits, not only for copying but also for revising, corresponds to a shift in the metaphorical and allegorical system which enables the parallel worlds of th…

Expression and differential localization of xenobiotic transporters in the rat olfactory neuro-epithelium.

2011

International audience; Transporters, such as multidrug resistance P-glycoproteins (MDR), multidrug resistance-related proteins (MRP) and organic anion transporters (OATs), are involved in xenobiotic metabolism, particularly the cellular uptake or efflux of xenobiotics (and endobiotics) or their metabolites. The olfactory epithelium is exposed to both inhaled xenobiotics and those coming from systemic circulation. This tissue has been described as a pathway for xenobiotics to the brain via olfactory perineural space. Thereby, olfactory transporters and xenobiotic metabolizing enzymes, dedicated to the inactivation and the elimination of xenobiotics, have been involved in the toxicological p…

Para-perirenal distribution of body fat is associated with reduced glomerular filtration rate regardless of other indices of adiposity in hypertensiv…

2018

Obesity is a well‐known risk factor for the development and progression of chronic kidney disease. Recently, para‐perirenal ultrasonographic fat thickness (PUFT) has shown to correlate with both total and visceral fat better than body mass index (BMI), waist circumference (WC), and other indices of obesity. Moreover, a local paracrine and mechanical action of the PUFT on kidney has been described in recent studies. Aim of our study was to assess the relationship between glomerular filtration rate (GFR) and PUFT in comparison with other anthropometric and ultrasonographic indices of adiposity. Two hundred and ninety‐six hypertensive patients were enrolled. PUFT, cutis‐rectis thickness and re…
