How bilastine is used to treat allergic rhinitis and urticaria in children
2021
Management guidelines for allergic rhinitis and urticaria recommend oral second-generation antihistamines as first-line treatment. The efficacy and safety of bilastine, the newest nonsedating second-generation antihistamine, are well established in adolescents/adults with these allergic conditions. The bilastine development program for pediatric use (2–<12 years) followed EMA-authorized processes. Pharmacokinetic/pharmacodynamic simulation and modeling and a pharmacokinetic study were conducted to identify and confirm the pediatric dose (10 mg/day). A Phase III, multicenter, double-blind, randomized, placebo-controlled, parallel-group study was performed to confirm the safety of bilasti…
Explotació dels mamífers i economia de les darreres comunitats caçadores-recol·lectores del vessant mediterrani ibèric durant la transició Tardiglaci…
2015
En el presente trabajo se realiza el estudio zooarqueológico de los vertebrados terrestres explotados por los grupos humanos de los niveles tardiglaciares de los yacimientos de Santa Maira (boca Oeste) y Nerja (sala del Vestíbulo). A partir de los datos obtenidos para las facies culturales Magdaleniense / Epipaleolítico / Mesolítico se caracterizan las tendencias de cambio en los modelos económicos de las últimas comunidades cazadoras-recolectoras de la península ibérica. Estas secuencias se contextualizan así mismo en la zona biogeográfica mediterránea peninsular. Entre los resultados obtenidos cabe destacar la definición y caracterización de un modelo económico "tardiglaciar", donde el mo…
Solvent Exchange in Thermally Stable Resorcinarene Nanotubes
2006
The assembly of C-methyl resorcinarene into a tubular supramolecular solid-state structure, its thermal stability, and its hosting properties are reported. Careful control of the crystallisation conditions of C-methyl resorcinarene and 1,4-dimethyl-1,4-diazoniabicyclo[2.2.2]octane (1,4-dimethyl DABCO) dibromide leads to a formation of two crystallographically different, but structurally very similar, solid-state nanotube structures. These structures undergo a remarkable variety of supramolecular interactions, which lead to the formation of 0.5 nm diameter nonpolar tubes through the crystal lattice. The formation of these tubes is templated by suitably sized small alcohols, namely, n-propano…

Measured and Modeled Residue Dynamics of Famoxadone and Oxathiapiprolin in Tomato Fields
2018
A reliable analytical method for the simultaneous determination of famoxadone and oxathiapiprolin dissipation kinetics as well as the metabolites of oxathiapiprolin (IN-E8S72 and IN-WR791) in tomato and soil was developed. We studied the dissipation of famoxadone and oxathiapiprolin in tomatoes grown using different kinetic curves in the area of Beijing in 2015 and 2016. Our results show that the most suitable model for two fungicides in 2015 and 2016 was first-order kinetic and second-order kinetic with the half-lives of 3.4 to 5.2 and 2.4 to 3.0 days, respectively. In addition, we applied the dynamic plant uptake model dynamiCROP and combined it with results from the field experiments to …
Spatial and temporal patterns of throughfall quantity and quality in a tropical montane forest in Ecuador
2007
Summary In forests, complex canopy processes control the change in volume and chemical composition of rain water. We hypothesize that (i) spatial patterns, (ii) the temporal stability of spatial patterns, and (iii) the temporal course of solute concentrations can be used to explore these processes. The study area at 1950 m above sea level in the south Ecuadorian Andes is far away from anthropogenic emission sources and marine influences. It received ca. 2200 mm of rain annually. We collected rain and throughfall on an event and within-event basis for five precipitation periods between August and October 2005 at up to 25 sites and analyzed the samples for pH and concentrations of K, Na, Ca, …
Characterisation of submarine groundwater discharge offshore south-eastern Sicily
2005
A complex approach in characterisation of submarine groundwater discharge (SGD) off south-eastern Sicily comprising applications of radioactive and non-radioactive tracers, direct seepage measurements, geophysical surveys and a numerical modelling is presented. SGD fluxes in the Donnalucata boat basin were estimated by direct seepage measurements to be from 4 to 12Ls(-1), which are comparable with the total SGD flux in the basin of 17Ls(-1) obtained from radon measurements. The integrated SGD flux over the Donnalucata coast estimated on the basis of Ra isotopes was around 60m(3)s(-1) per km of the coast. Spatial variations of SGD were observed in the Donnalucata boat basin, the average (222…
Automated Determination of Paroxetine and Its Main Metabolite by Column Switching and On-Line High-Performance Liquid Chromatography
1994
An automated column-switching method coupled to isocratic high-performance liquid chromatography has been developed for simultaneous determination of blood levels of paroxetine and its nonconjugated main metabolite BRL 36610. The lower limits of detection were 9-15 nmol/L (3-5 ng/ml) and linearity between drug concentration and detector response was found for 0-1,500 nmol/L (0-500 ng/ml). The method could be applied to the analysis of serum samples obtained from depressed patients who were treated with daily oral doses of 20 or 40 mg of paroxetine. After the 20-mg dose, the mean blood level of paroxetine was 69 nM (23 ng/ml), whereas the metabolite BRL 36610 was detectable in only one of 5 …
Fluorescence labelling of organic acidic compounds with 4-bromomethyl-7-methoxycoumarin (Br-Mmc)
1977
4-Bromomethyl-7-methoxycoumarin (Br-Mmc) is introduced as a fluorescence marker for aromatic and heterocyclic acids. To investigate the applicability of this method on substances of different chemical classes, screening experiments with 110 compounds were carried out using a microrefluxer. Most aromatic and heterocyclic monocarboxylic acids gave Mmc-esters which are fluorescent on thin-layer plates, like the Mmc-esters of fatty acids, which have been previously investigated. Strong acids, alcohols, amides and most amines did not react, whereas certain cyclic amines such as piperidine gave strongly fluorescent derivatives. Mmc-phenyl ethers shows only weak fluorescence. A new standard proced…
Synthesis and evaluation of microtubule assembly inhibition and cytotoxicity of prenylated derivatives of cyclo-l-Trp-l-Pro
2000
The synthesis of three isoprenylated derivatives of cyclo-L-Trp-L-Pro is described. These substances have been evaluated for cytotoxic activity in rat normal fibroblast 3Y1 cells and have also been evaluated in vitro for the inhibition of microtubule assembly.
