We developed mice deficient in protease-activated receptor-2 (PAR-2) or PAR-1 to explore the pathophysiological functions of these receptors. In this report, we evaluated mean arterial pressure and heart rate (HR) changes in response to PAR-1 or PAR-2 activation in anesthetized wild-type (WT), PAR-1-deficient (PAR-1(-/-)), and PAR-2-deficient (PAR-2(-/-)) mice. In WT mice, TFLLRNPNDK, a PAR-1 s...

The ubiquitously occuring non-specific lipid-transfer proteins (nsLTPs) in plants are implicated in key processes like biotic and abiotic stress, seed development and lipid transport. Additionally, they constitute a panallergen multigene family present in both food and pollen. Presently there are 49 nsLTP entries in the WHO/IUIS allergen database (http://allergen.org/). Analysis of full-length ...

Preuve Soit (E,+, •) un K-espace vectoriel. Soit I un ensemble fini. Une famille (ui)i∈I ∈ E d’éléments de E. — (⇒) Si (ui)i∈I est libre. I est un sous-ensemble fini de I. Puis par la définition 1.1, pour tout toute famille de scalaires (λi)i∈I , on a : ∑ i∈I λi •ui = 0E ⇔ ∀i ∈ I, λj = 0. — (⇐) On suppose que pour tout toute famille de scalaires (λi)i∈I , on a : ∑ i∈I λi • ui = 0E ⇔ ∀i ∈ I, λj ...

— The words “monodromy” and “isomonodromy” are used in the theory of difference and q-difference equations by Baranovsky-Ginzburg, Jimbo-Sakai, Borodin, Krichever,... although it is not clear that phenomena of branching during analytic continuation are involved there. In order to clarify what is at stake, we survey results obtained during the last few years, mostly by J.-P. Ramis, J. Sauloy and...

The serine/threonine kinase, PAR-1, is an essential component of the evolutionary-conserved polarity-regulating system, PAR-aPKC system, which plays indispensable roles in establishing asymmetric protein distributions and cell polarity in various biological contexts (Suzuki, A. and Ohno, S. (2006). J. Cell Sci., 119: 979-987; Matenia, D. and Mandelkow, E.M. (2009). Trends Biochem. Sci., 34: 332...

Pear psylla, Cacopsylla pyricola (Förster) (Hemiptera: Psyllidae), is a pest of pears, Pyrus L. (Rosaceae), throughout North America and western Europe. Previous studies in our laboratory showed that males of the overwintering form (winter morphotype) were attracted to volatile chemicals from pear shoots infested with post-diapause females. The current study shows that males of the summer morph...

2. Etude du LASSO 2.1. Erreur de prédiction. Proposition 2.1. Soit ŵ ∈ Argmin(J). Si ∆ = ŵ−w∗, et ||Ω||∞ ≤ λ2 , alors ||∆Jc ||1 ≤ 3||∆J ||1, où on note J le support de w∗. Pour démontrer cette proposition on rappelle des résultats sur la norme duale. Définition 1. Soit N une norme sur R, ∀y,N∗(y) = supN(x)≤1 x>y Proposition 2.2. La norme duale est une norme, et vérifie N∗∗ = N . ∀(x, y), x>y ≤ ...

This work focuses on: (1) understanding the impact of sinkhole attacks on treebased routing topologies in Wireless Sensor Networks (WSNs), and (2) investigating cryptography-based strategies to limit network degradation caused by these attacks. This work is particularly important as WSN protocols that construct a fixed routing topology may be significantly affected by malicious attacks. Further...
