Abstract: A powerful technique was developed for the identification and quantification of 9 volatile compounds of beer, using headspace solid phase micro‐extraction (HS/SPME) and gas chromatograph coupled to a mass spectrometer and a flame ionization detector (GC/MS/FID). Optimized parameters included type of fiber, desorption time, and exposure time. Optimization was achieved with standard solutions of the target compounds. All samples were analyzed in triplicate. An exposure time of 45 min with ...

The dynamics of glass-forming liquids shows universal features like non-Debye behavior, scaling, and non-Arrhenius temperature dependence of the characteristic rates. These features have been mainly established in the time range between ${10}^{\mathrm{\ensuremath{-}}9}$ and 10 s. It is well known that when the temperature of a glass-forming liquid is lowered and the characteristic relaxation time becomes larger than hundreds of seconds, the system falls out of equilibrium and a glass is obtained. ...

The aim of present work is to evaluate the transfection capacity of a new multicomponent system based on dextran (Dex), protamine (Prot), and solid lipid nanoparticles (SLN) after intravenous administration to mice. The vectors containing the pCMS-EGFP plasmid were characterized in terms of particle size and surface charge. In vitro transfection capacity and cell viability were studied in four cell lines, and compared with the transfection capacity of SLN without dextran and protamine. Transfection ...

Bleomycin has progressively been used to treat low-flow vascular malformations in children. No significant systemic side effects have been reported in large series after low doses, but some authors are still concerned about its use. We report a case of a severe acute lung toxicity after a low dose of a second bleomycin intralesional injection in a 5-year-old girl. She had no risk factors and presented a cervical low-flow venous malformation. Twenty-four hours after this second administration, she ...

Abstract Nutritional management of very long‐chain acyl‐CoA dehydro‐genase (VLCAD) deficiency is based on the avoidance of fasting and substitution of medium‐chain triglycerides for long‐ and very long‐chain triglycerides. We report two cases of this disease, which developed ω‐6 essential fatty acid deficiency after three and five months from the beginning of nutritional therapy (SHS product: Monogen). This alteration could be especially dangerous in these patients owing to their possible susceptibility ...

Abstract Agriculture first reached the Iberian Peninsula around 5700 BCE. However, little is known about the genetic structure and changes of prehistoric populations in different geographic areas of Iberia. In our study, we focus on the maternal genetic makeup of the Neolithic (~ 5500–3000 BCE), Chalcolithic (~ 3000–2200 BCE) and Early Bronze Age (~ 2200–1500 BCE). We report ancient mitochondrial DNA results of 213 individuals (151 HVS-I sequences) from the northeast, central, southeast and southwest regions ...
