Fluorescence emission and enhanced photochemical stability of Zn(II)-5-triethyl ammonium methyl salicylidene ortho-phenylendiiminate interacting with…

2010

Abstract The photophysical and photochemical properties of the cationic Zn II complex of 5-triethyl ammonium methyl salicylidene ortho-phenylendiimine (ZnL 2+ ) interacting with native DNA were investigated by steady state and time-resolved fluorescence spectroscopies. Experimental results indicate that, in the presence of DNA, ZnL 2+ is efficiently protected from a photochemical process, which occurs when it is in the free state dispersed in aqueous solution. The analysis of the absorption and emission spectra of ZnL 2+ , both stored in the dark and after exposure to tungsten lamp light for 24 h, corroborated by quantum chemical calculations, allowed us to point out that ZnL 2+ undergoes a…

Immunological Probes for the Bradykinin B2 Receptor. A Toolbox

1997

Publisher Summary This chapter provides an overview of the immunological tools for bradykinin (BK) B 2 receptor. Receptors for kinins are classified as two major subtypes, B 1 and B 2 , although other subtypes may exist. B 1 receptors are activated by carboxyterminally truncated kinins, whereas BK and kallidin (Lys-BK) are B 2 receptor agonists. Molecular cloning has revealed the primary structures of B 1 and B 2 receptors and identified them as members of the G protein-coupled receptor family, characterized by seven membrane-spanning α-helices. In some tissues, B 1 receptor expression is induced by cytokines, such as interleukin-1, whereas the B 2 receptor is thought to be expressed consti…

Przedstawione zasady to: zasada integracji, walidacji, kontekstualizacji oraz aktywacji. Zaprezentowane działania, techniki i narzędzia, które wynikają ze stosowania ogólnych zasad doskonalen…

Neuronal intestinal dysplasia

1987

Findings in 23 children with neuronal intestinal dysplasia (NID) are presented. Twelve children had Hirschsprung's disease that masked the existence of proximal NID. In all cases the diagnosis was established by histological-histochemical examination. Amelioration of symptoms by conservative treatment alone was achieved in 4 children; in 13 cases colostomy was necessary. In 6 patients colon resection was performed: 2 suffered from both colitis and obstruction; the other 4 were treated for obstruction, multiple perforations, persistant adynamia of the left colon, and fistulation. In 9 patients the colostomy was closed. Four of 6 children who did not have sonographic confirmation of motility …

Fruit quality and volatile fraction of ‘Pink Lady’ apple trees in response to rootstock vigor and partial rootzone drying

2008

BACKGROUND: Partial rootzone drying (PRD) is a novel deficit irrigation technique consisting in the alternated wetting of only one side of the rootzone, which induces partial stomatal closure and increased water use efficiency. The effect of PRD and rootstock vigor on ‘Pink Lady’ apple fruit quality and aroma profile was studied using solid-phase micro-extraction in headspace and gas chromatography/mass spectrometry. RESULTS: PRD irrigation generally did not affect quality attributes, whereas it influenced the aroma of the apple fruit. In particular, PRD improved the aroma of the fruit flesh, while it decreased the volatile fraction in the peel, where most of the compounds are concentrated.…

Renal and nonrenal clearances of ceftriaxone at the steady-state and its relation to plasma protein binding

1995

Abstract The effect of the saturable plasma protein binding of ceftriaxone on the elimination of this drug was studied under steady-state conditions in the rat. A concentration-dependent increase in the total, renal and nonrenal clearances of total drug (bound + unbound) was observed, and it was related to the increase in the ex vivo unbound fraction of ceftriaxone as the plasma concentration increased. The nonrenal clearance of the unbound ceftriaxone showed a statistically significant decrease as the plasma concentration of the unbound drug at the steady state increased, which indicates that the nonrenal elimination of the drug (mainly by biliary excretion) is a saturable process. Renal c…

Celebrity practice in networked media : a case study of Lady Gaga and Twitter

2014

Tutkielman tarkoitus oli selvittää, millä tavoin poplaulaja Lady Gaga käyttää yhteisö- ja mikroblogipalvelu Twitteriä aktiiviseen julkisuuden harjoittamiseen. Aineisto koostui 207 Lady Gagan julkaisemasta tweetistä eli mikroblogimerkinnästä, jotka kerättiin Twitteristä valitsemalla satunnainen kahden kuukauden mittainen ajanjakso, joka oli tässä tapauksessa marras-joulukuu 2012. Tutkielman tavoite oli tutkia, mihin tarkoituksiin Lady Gaga käyttää Twitteriä, eli mitä eri funktioita hänen julkisuuden harjoittamisensa toteuttaa. Toisena tavoitteena oli selvittää, millaisia keinoja Lady Gaga käyttää näiden funktioiden toteuttamisessa, ja mitkä ovat hänelle tyypillisiä piirteitä julkisuuden harj…

Energy status and its control on embryogenesis of legumes: ATP distribution within Vicia faba embryos is developmentally regulated and correlated wit…

2003

To analyse the energy status of Vicia faba embryos in relation to differentiation processes, we measured ATP concentrations directly in cryosections using a quantitative bioluminescence-based imaging technique. This method provides a quantitative picture of the ATP distribution close to the in vivo situation. ATP concentrations were always highest within the axis. In pre-storage cotyledons, the level was low, but it increased strongly in the course of further development, starting from the abaxial region of cotyledons and moving towards the interior. Greening pattern, chlorophyll distribution and photosynthetic O2 production within embryos temporally and spatially corresponded to the ATP di…

Some diffusion equations with finite propagation speed

2007

We summarize some of our recent results on diffusion equations with finite speed of propagation. These equations have been introduced to correct the infinite speed of propagation predicted by the classical linear diffusion theory. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
