Two new species of Brusqeulia Razowski & Becker, 2000 from the Neotropics, with comments on the systematic position of the genus in relation to the A…
2018
Two new species of the neotropical genus Brusqeulia Razowski & Becker, 2000, are described and illustrated: B. yunkensis Pérez Santa-Rita & Baixeras, sp. n. from Bolivia and B. araguensis Pérez Sant-Rita & Baixeras, sp. n. from Venezuela. The systematic position and diagnostic characters of the genus are reviewed, resulting in the synonymy of Pinhaisania Razowski & Becker, 2000, with Brusqeulia, and the combination B. crispula (Razowski & Becker, 2000), comb. n. New characters of the female genitalia are discussed.

Noise reduction in magnetic resonance images by Wavelet transforms: an application to the study of capillary water absorption in sedimentary rocks
2007
Magnetic resonance imaging (MRI) is a powerful technique to study capillary water absorption kinetics in sedimentary rocks. However, the noise in the images can limit the correct identification and the quantitative measurement of the average height reached by the wetting front inside the porous material where imbibition occurs. Therefore, denoising methods can be applied to improve the image quality for a more accurate analysis, without the disadvantages of longer acquisition times. This study attempts to improve the signal-to-noise ratio of the images acquired by MRI on a sedimentary rock (Pietra di Lecce) using a waveletbased thresholding technique. The idea is to average some slightly di…
Obesity alters the gustatory perception of lipids in the mouse: plausible involvement of lingual CD36. : Obesity decreases the fat preference
2013
International audience; A relationship between orosensory detection of dietary lipids, regulation of fat intake, and body mass index was recently suggested. However, involved mechanisms are poorly understood. Moreover, whether obesity can directly modulate preference for fatty foods remains unknown. To address this question, exploration of the oral lipid sensing system was undertaken in diet-induced obese (DIO) mice. By using a combination of biochemical, physiological, and behavioral approaches, we found that i) the attraction for lipids is decreased in obese mice, ii) this behavioral change has an orosensory origin, iii) it is reversed in calorie-restricted DIO mice, revealing an inverse …
CD36 involvement in orosensory detection of dietary lipids, spontaneous fat preference, and digestive secretions
2005
International audience; Rats and mice exhibit a spontaneous attraction for lipids. Such a behavior raises the possibility that an orosensory system is responsible for the detection of dietary lipids. The fatty acid transporter CD36 appears to be a plausible candidate for this function since it has a high affinity for long-chain fatty acids (LCFAs) and is found in lingual papillae in the rat. To explore this hypothesis further, experiments were conducted in rats and in wild-type and CD36-null mice. In mice, RT-PCR experiments with primers specific for candidate lipid-binding proteins revealed that only CD36 expression was restricted to lingual papillae although absent from the palatal papill…
Lipid-mediated release of GLP-1 by mouse taste buds from circumvallate papillae: putative involvement of GPR120 and impact on taste sensitivity
2012
Glucagon-like peptide-1 (GLP-1) signaling modulates sweet-taste sensitivity in the mouse. Because circumvallate papillae (CVPs) express both GLP-1 and its receptor, a local regulation has been suggested. However, whether dietary lipids are involved in this regulation, as shown in the gut, is unknown. By using a combination of biochemical, immunohistochemical, and behavioral approaches, the present data i) confirm the role of GLP-1 signaling in the attraction for sucrose, ii) demonstrate that minute quantities of long-chain FAs (LCFAs) reinforce the attraction for sucrose in a GLP-1 receptor-dependent manner, iii) suggest an involvement of the LCFA receptor GPR120 expressed in taste buds in …
Human Papillomavirus Type 33 E7 Peptides Presented by HLA-DR*0402 to Tumor-Infiltrating T Cells in Cervical Cancer
2000
ABSTRACTSeveral characteristics make human papillomavirus (HPV) amenable to vaccination. Anti-HPV-directed vaccines are based on the observation that HPV E6 and E7 oncoproteins are constitutively expressed in HPV-positive cervical cancer and may serve as tumor rejection antigens. Five HPV types (16, 18, 31, 33, and 45) account for 80% of cervical cancer. Until now, the type of immune response capable of mediating an effective antitumor response has not been defined. In order to define the anticancer-directed immune response in situ, we characterized CD4+and CD8+sorted T cells from peripheral blood lymphocytes, freshly harvested tumor tissue, and tumor-infiltrating lymphocytes (TIL) from a p…
How credit ratings affect sovereign credit risk: cross-border evidence in Latin American emerging markets
2017
This article builds upon previous literature by providing a better understanding of how contagion changes in bordering sovereign CDS emerging markets resulting from credit rating events. To that end, we follow the novel GVAR methodology using data from six Latin American emerging countries during an extensive sample period from 2004 to 2014. Our findings show evidence for the existence of significant and asymmetric cross-border effects. In particular, a competition effect is observed before the event occurs, indicating that non-event countries suffer (benefit) from upgrades (downgrades) in Brazil, Mexico and Chile (in Argentina and Brazil). In contrast, an imitation effect is observed after…
Do sovereign ratings cause instability in cross-border emerging CDS markets?
2020
We analyse the cross-border transmission effect of credit ratings on sovereign CDSs covering a broad sample of emerging countries during the period 2004 to 2015. This study differentiates between the spillover and competition effects between and within geographical areas of emerging countries. We find substantial evidence of cross-border effects with asymmetric responses to upgrades and downgrades. The market reaction differs across regions, reflecting how the international and local impact of rating events are due to different types of effects. At the international portfolio level, the competitive effect is dominant over the spillover effect. Negative events in Asia benefit Africa (which i…
