Korpusonomastinen tutkimus slanginimistä Hesa ja Stadi digitaalisissa diskursseissa
2019
Artikkelissamme selvitämme Helsinkiä tarkoittavien slanginimien, Hesan ja Stadin, käyttöä uudentyyppisen aineiston ja menetelmän avulla. Aiemmissa näitä nimiä koskevissa tutkimuksissa lähtökohta on ollut kvalitatiivinen, mutta tässä tutkimuksessa lähdemme liikkeelle laajasta digitaalisesta aineistosta ja tilastollisista menetelmistä. Tutkimuksemme on uusi avaus nimistöntutkimuksessa, ja nimitämme sitä korpusavusteiseksi nimistöntutkimukseksi, lyhyemmin korpusonomastiikaksi.
 Aineistonamme on laaja Suomi24-keskustelufoorumista muodostettu ja Kielipankista saatava Suomi24-korpus, josta olemme hakeneet Hesa- ja Stadi-nimet. Tutkimus toteutetaan korpusavusteisena diskurssintutkimuksena. Mo…
Design of new sensitive α,β-unsaturated carbonyl 1,8-naphtalimide fluorescent probes for thiol bioimaging
2017
International audience; We report herein an efficient synthesis of news naphtalimide-based fluorescent derivatives functionalized with an a,(3-unsaturated carbonyl group. Probes were synthesized from reaction of an amino-naphtalimide precursor with maleic anhydride. Photophysical study of fluorescent probes and cells labelling were performed, and showed that the reactive derivatives exhibit rich turn on fluorescence properties in presence of different biological thiol (Glutathione and Cysteine) making these systems a very promising way for thiol bioimaging.
Estudio del estrés oxidativo hepático asociado a la enfermedad de Alzheimer. Efecto del tratamiento con bexaroteno y/o genisteína
2013
La enfermedad de Alzheimer (EA) no tiene una etiología perfectamente definida. Una de las teorías que se barajan como causa de la EA es la del péptido β-amiloide (βA). Esta molécula es neurotóxica y es capaz de producir estrés oxidativo. Se forma principalmente en el cerebro y se acumula formando placas extracelulares. Se ha sugerido que el βA es el eje principal de la EA, y por tanto que a partir de esta molécula se desencadenan todos los procesos asociados a la EA, lo que se ha llamado la cascada amiloidea. Otra de las hipótesis es la que la relaciona con el estrés oxidativo. Este factor sería el agente que realmente provoca toda la serie de cambios descritos en los tejidos nerviosos, a t…

Kaon femtoscopy in Pb-Pb collisions at √sNN=2.76 TeV
2017
We present the results of three-dimensional femtoscopic analyses for charged and neutral kaons recorded by ALICE in Pb-Pb collisions at √ s NN = 2.76 TeV. Femtoscopy is used to measure the space-time characteristics of particle production from the effects of quantum statistics and final-state interactions in two-particle correlations. Kaon femtoscopy is an important supplement to that of pions because it allows one to distinguish between different model scenarios working equally well for pions. In particular, we compare the measured three-dimensional kaon radii with a purely hydrodynamical calculation and a model where the hydrodynamic phase is followed by a hadronic rescattering stage. The…
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.

Characterization of particle morphology of biochanin A molecularly imprinted polymers and their properties as a potential sorbent for solid-phase ext…
2014
Abstract Molecularly imprinted polymers (MIPs) with biochanin A as a template were obtained using a bulk polymerization with non-covalent imprinting approach. The polymers were prepared in acetonitrile as porogen, using ethylene glycol dimethacrylate (EDMA) as cross-linking agent. The synthesis, with an application of 1′,1′-azobis(cyclohexanecarbonitrile) (ACHN) as an initiator, has been performed thermally. During the synthesis process the effect of different functional monomers such as methacrylic acid (MAA), acrylamide (AA) and 4-vinylpyridine (4-VP) was investigated. The application of nitrogen sorption porosimetry, scanning electron microscopy (SEM), and Fourier transform infrared spec…

Exposure assessment of Spanish lactating mothers to acrylamide via human biomonitoring.
2021
Abstract Acrylamide (AA) is an organic compound classified as “Probably carcinogenic to humans” (Group 2 A) that can be found principally in processed carbohydrate-rich foods and tobacco smoke. In humans, after exposure, AA is rapidly metabolized and excreted in urine, predominantly as N-acetyl-S-(2-carbamoylethyl)-l-cysteine (AAMA), N-acetyl-S-(2-carbamoyl-2-hydroxyethyl)-l-cysteine (GAMA3) and N-Acetyl-3-[(3-amino-3-oxopropyl)sulfinyl]-L-alanine (AAMA-Sul), which can be used as short-term biomarkers of exposure to AA. In this study, the presence of AA metabolites in urine samples of lactating mothers living in Spain (n = 114) was analyzed by “dilute and shoot” and liquid chromatography co…
