Imprinting of CCR9 on CD4 T cells requires IL-4 signaling on mesenteric lymph node dendritic cells (AMER ASSOC IMMUNOLOGISTS, 2008-05-15)It has recently been shown that IL-4 can educate dendritic cells (DC) to differentially affect T cell effector activity. In this study, we show that IL-4 can also act upon DC to instruct naive T cells to express the ...

(SPRINGER, 2006-01)As a consequence of the increasing importance of hydrogen peroxide in plant metabolism, more efficient methods are required for accurate determinations of its concentration in plant tissue and organs. Here we present a ...

Improved Predictions of the Geographic Distribution of Invasive Plants Using Climatic Niche Models (Public Library Science, 2016)Climatic niche models for invasive plants are usually constructed with occurrence records taken from literature and collections. Because these data neither discriminate among life-cycle stages of plants (adult or juvenile) ...

(Springer, 2016)We report a computational study of a series of organic dyes built with triphenylamine (TPA) as an electron donor group. We designed a set of six dyes called (TPA-n, where n=0-5). In order to enhance the electron-injection ...
-
(2006)BGLII is a bacterial endoglucanase that hydrolyzes the β-1,3-glucan present in yeast cell walls, resulting in lysis of Saccharomyces cerevisiae. As a result of this property, BGLII is considered a potential tool for ...
-
(Nordic Pharmacological Society), 2014)Abstract: Amphetamine derivatives have therapeutic potential in diseases such as attention deficit hyperactivity disorder, narcolepsy and obesity. However, their prolonged use has been associated with cardiovascular ...
-
(Elsevier, 2019)To better understand the effect of surface treatments on the efficiency of protective coatings of aluminum alloys, this study assessed different surface treatments for the aluminum alloy AA2024, including mechanical ...
-
(ELSEVIER, 2006-01-30)We study the properties of localized impurity modes and the transmission of plane waves across a general nonlinear impurity embedded in an infinite one-dimensional linear chain. Using the formalism of the lattice Green ...
-
(1990)The impurity-induced grain-boundary decohesion is investigated on the basis of a three-dimensional-model calculation. The grain boundary is simulated by self-consistently modifying the hopping integrals between two neighboring ...
-
(Springer, 2013)In our quest to explore molecules with chemically significant regions where the Fukui function is negative, we explored reactions where the frontier orbital that indicates the sites for electrophilic attack is not the ...
-
(Springer Verlag, 2014)A justification for the likely presence of negative Fukui functions in molecules with small band gaps is given, and a computational study performed to check whether molecules with small band gaps have negative Fukui functions ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2010-05-06)Homology models of nicotinic acetylcholine receptors (nAChRs) suggest that subtype specificity is due to non-conserved residues in the complementary subunit of the ligand-binding pocket. Cytisine and its derivatives ...
-
(Frontiers Media, 2021)The pandemic that started in Wuhan (China) in 2019 has caused a large number of deaths, and infected people around the world due to the absence of effective therapy against coronavirus 2 of the severe acute respiratory ...
-
(Springer, 2016)Evidence of guest migration in α-cyclodextrin-octylamine (α-CD-OA) inclusion compound (IC) generated via plasmonic heating of gold nanoparticles (AuNPs) has been studied. In this report, we demonstrate local effects ...
-
(1998)Fetal cystoscopy was performed in nine fetuses with sonographic evidence of lower urinary tract obstruction and normal urinary electrolytes. Posterior urethral valves (PUV) were thought to be present in all cases. Endoscopic ...

(2011)The in vitro effect of the resinous exudate of Heliotropium filifolium, of the 3 H-spiro[1-benzofuran-2,1'-cyclohexane] derivative called filifolinol 1, isolated from the resin and the semi-synthetic compounds filifolinone ...
