Les paradoxes du glufosinate et glyphosate. Comportement dans l'ambroisie à feuilles d'armoise

2006

BEHAVIOUR OF GLUFOSINATE ANDGLYPHOSATE IN COMMONRAGWEED:APPARENT PARADOXAND SURPRISES We examined the foliar epidermis of commonragweed (Ambrosia artemisiifolia L.) plants and studied the behaviour of the herbicides glufosinate and glyphosate in this species. Both leaf surfaces exhibited 3 types of trichomes, according to their size and shape. Epicuticular waxes appeared amorphous, which may explain high levels of spray retention. Glufosinate and glyphosate were rapidly and almost completely taken up by common ragweed leaves; half maximum uptake was nearly reached after 5 and 3 h, respectively. The longest trichomes were stained with AgN03, indicating the presence of hydrophilic domains, wh…

On the arithmetic and geometry of binary Hamiltonian forms

2011

Given an indefinite binary quaternionic Hermitian form $f$ with coefficients in a maximal order of a definite quaternion algebra over $\mathbb Q$, we give a precise asymptotic equivalent to the number of nonequivalent representations, satisfying some congruence properties, of the rational integers with absolute value at most $s$ by $f$, as $s$ tends to $+\infty$. We compute the volumes of hyperbolic 5-manifolds constructed by quaternions using Eisenstein series. In the Appendix, V. Emery computes these volumes using Prasad's general formula. We use hyperbolic geometry in dimension 5 to describe the reduction theory of both definite and indefinite binary quaternionic Hermitian forms.

Alkamides from Echinacea angustifolia Interact with P-Glycoprotein of Primary Brain Capillary Endothelial Cells Isolated from Porcine Brain Blood Ves…

2013

The blood-brain barrier prevents the passage of toxic compounds from blood circulation into brain tissue. Unfortunately, drugs for the treatment of neurodegenerative diseases, brain tumors, and other diseases also do not cross the blood-brain barrier. In the present investigation, we used isolated porcine brain capillary endothelial cells and a flow cytometric calcein-AM assay to analyze inhibition of P-glycoprotein, a major constituent of the blood-brain barrier. We tested 8 alkamides isolated from Echinacea angustifolia and found that four of them inhibited P-glycoprotein-mediated calcein transport in porcine brain capillary endothelial cells.

Giant hepatocellular adenoma as cause of severe abdominal pain: a case report

2007

Abstract The authors describe the case of a large hepatocellular adenoma diagnosed in a 30-year old woman who came to us complaining of acute pain in the upper abdominal quadrants. The patient had been taking an oral contraceptive pill for the last ten years. We present the clinical features, the diagnostic work-up and the treatment prescribed.

Abdominal wall reconstruction by a regionally distinct biocomposite of extracellular matrix digest and a biodegradable elastomer.

2013

Current extracellular matrix (ECM) derived scaffolds offer promising regenerative responses in many settings, however in some applications there may be a desire for more robust and long lasting mechanical properties. A biohybrid composite material that offers both strength and bioactivity for optimal healing towards native tissue behavior may offer a solution to this problem. A regionally distinct biocomposite scaffold composed of a biodegradable elastomer (poly(ester urethane)urea) and porcine dermal ECM gel was generated to meet this need by a concurrent polymer electrospinning/ECM gel electrospraying technique where the electrosprayed component was varied temporally during the processing…

Educación compensatoria : aprendizaje temprano, éxito posterior : (II: el Carolina Abecedarian Project)

2014

Este es un estudio de revisión en el que se analizan las investigaciones que evalúan los efectos a lo largo del tiempo del programa de educacióntemprano Abecedarian Project (ABC). El ABC es un programa compensador preventivo de 0-5 años y entresacados de madres de alto riesgo. El grupo experimental (E) recibe tratamiento preescolar intensivo, no el control (C). Se prolongó escolarmente hasta los 8 años, subdividiéndose ambos grupos: Dos -EE y CE- recibieron tratamiento intensivo; otros (EC y CC) convencional. Fueron medidos hasta los 21. Resultados: Los jóvenes adultos, tratados preescolarmente, mejoraron en rendimiento mental, lector y matemático; alcanzaron mayores instrucciones y presenc…

The Intention-to-Treat Effect of Bridging Treatments in the Setting of Milan Criteria–In Patients Waiting for Liver Transplantation

2019

In patients with hepatocellular carcinoma (HCC) meeting the Milan criteria (MC), the benefit of locoregional therapies (LRTs) in the context of liver transplantation (LT) is still debated. Initial biases in the selection between treated and untreated patients have yielded conflicting reported results. The study aimed to identify, using a competing risk analysis, risk factors for HCC-dependent LT failure, defined as pretransplant tumor-related delisting or posttransplant recurrence. The study was registered at www.clinicaltrials.gov (identification number NCT03723304). In order to offset the initial limitations of the investigated population, an inverse probability of treatment weighting (IP…

Do Cross-Country Differences in Accounting Conservatism Explain Variations in the Degree of Investor Diversification?

2009

We show that the level of conditional accounting conservatism of foreign markets is significantly and positively associated with decisions to diversify portfolios internationally. This positive association could be either because conditional conservatism per se is attractive to international investors, or because the un-modelled factors that attract foreign investors to a country also cause these countries to adopt conditionally conservative accounting practices. However, if conditional conservatism serves to alleviate foreign investors’ concerns related to insiders having asymmetric access to information then one would also expect the chosen mode of entry into a foreign market (as foreign …
