Effects of ageing on peroxidase activity and localization in radish (Raphanus sativus L.) seeds.
2010
Peroxidase activity was assayed in crude extracts of integument, cotyledons and embryo axis of radish seeds, deteriorated under accelerated ageing conditions. Over five days of ageing, in which germination decreased from 100 to 52%, the enzyme activity in integument was higher than that in other seed parts, increasing in the first days of ageing and then decreasing sharply in extremely aged seeds. Polyacrylamide gel electrophoresis analysis showed four peroxidase isoenzymes with MM of 98, 52.5, 32.8 and 29.5 kDa in the embryo axis of unaged seeds, and only the 32.8 and 29.5 kDa MM isoforms in the integument and cotyledons. In these parts of the seed, only the 29.5 kDa MM isoenzyme increased…
Galantamine is an allosterically potentiating ligand of neuronal nicotinic but not of muscarinic acetylcholine receptors.
2003
Galantamine (Reminyl), an approved treatment for Alzheimer's disease (AD), is a potent allosteric potentiating ligand (APL) of human alpha 3 beta 4, alpha 4 beta 2, and alpha 6 beta 4 nicotinic receptors (nAChRs), and of the chicken/mouse chimeric alpha 7/5-hydroxytryptamine3 receptor, as was shown by whole-cell patch-clamp studies of human embryonic kidney-293 cells stably expressing a single nAChR subtype. Galantamine potentiates agonist responses of the four nAChR subtypes studied in the same window of concentrations (i.e., 0.1-1 microM), which correlates with the cerebrospinal fluid concentration of the drug at the recommended daily dosage of 16 to 24 mg. At concentrations10 microM, gal…

Free sequences and the tightness of pseudoradial spaces
2019
Let F(X) be the supremum of cardinalities of free sequences in X. We prove that the radial character of every Lindelof Hausdorff almost radial space X and the set-tightness of every Lindelof Hausdorff space are always bounded above by F(X). We then improve a result of Dow, Juhasz, Soukup, Szentmiklossy and Weiss by proving that if X is a Lindelof Hausdorff space, and $$X_\delta $$ denotes the $$G_\delta $$ topology on X then $$t(X_\delta ) \le 2^{t(X)}$$ . Finally, we exploit this to prove that if X is a Lindelof Hausdorff pseudoradial space then $$F(X_\delta ) \le 2^{F(X)}$$ .
Cardinal estimates involving the weak Lindelöf game
2021
AbstractWe show that if X is a first-countable Urysohn space where player II has a winning strategy in the game $$G^{\omega _1}_1({\mathcal {O}}, {\mathcal {O}}_D)$$ G 1 ω 1 ( O , O D ) (the weak Lindelöf game of length $$\omega _1$$ ω 1 ) then X has cardinality at most continuum. This may be considered a partial answer to an old question of Bell, Ginsburg and Woods. It is also the best result of this kind since there are Hausdorff first-countable spaces of arbitrarily large cardinality where player II has a winning strategy even in the weak Lindelöf game of countable length. We also tackle the problem of finding a bound on the cardinality of a first-countable space where player II has a wi…
Nuevos datos sobre Ferula loscosii (Lange) Willk. (Apiaceae) en la provincia de Alicante
2012
Se amplía el área de distribución del endemismo ibérico Ferula loscosii en el noroeste de la provincia de Alicante, al haber sido hallados nuevos núcleos poblacionales situados a una distancia de hasta 4 km respecto al único núcleo anteriormente conocido en Villena. Asimismo se adjunta abundante material gráfico y descriptivo sobre las plantas alicantinas para facilitar tanto su comparación con el resto de poblaciones ibéricas como la futura detección de nuevas poblaciones de esta especie. The distribution area of the Iberian endemism Ferula loscosii is enlarged in NW Alicante province. New populations have been found which are located up to 4 km far from the single population currently kno…
Studio di segmentazione morfovolumetrica in pazienti con declino cognitivo lieve amnestico (aMCI) e demenza di Alzheimer (AD) rispetto ad un gruppo d…
2016
SCOPO: Presentare i risultati preliminari di un’analisi di segmentazione morfovolumetrica (VBM) eseguita in pazienti con aMCI ed AD rispetto ad una popolazione di controllo (NAB). Tali dati saranno in futuro correlati ad altri parametri clinico-psicologici raccolti (età, sesso, scolarità, MMSE, ADL, IADL). MATERIALI E METODI: Sono stati sottoposti ad esame RM encefalo 103 soggetti, utilizzando uno scanner RM GE Signa HDxt da 1,5T ed acquisendo, tra le altre, una sequenza Sag 3D T1 FSPGR IR preped ASSET che è stata utilizzata per l’analisi VBM eseguita con il tool sienax (FSL). I risultati sono stati valutati in termini di valori medi e deviazioni standard mediante applicazione del t-test…
