The article focuses on the study regarding the effects of sevoflurane anaesthesia administration to domestic animals, specifically the Iberian lynx. The study involves six Iberian lynx which had been captured for medical and reproductive control purposes. The drug was administered at five percent in oxygen using a calibrated vapolizer. The study found that medetomidine induces a useful degree of sedation for mask induction of anaesthesia with sevoflurane.

Knowledge of past local to regional climate variability is a priority research area as the magnitude of climate change at these scales can be greater than at the global level. Peatlands are sensitive to hydro-climate change and represent a significant carbon (C) pool in the terrestrial biosphere. Here, we applied a multi-proxy approach (bulk density, loss on ignition, total organic carbon, testate amoebae, δ 13 C in Sphagnum , plant macrofossils, pollen and charcoal) and Bayesian statistics to a peat sequence from a mountain ombrogenous bog (Tăul Muced) to explore how changes in hydrological conditions, peat plant composition and disturbances have affected long-term physical peat properties and the rate of C accumulation over the last ca. 8800 years. We found that C accumulation at this site ranged from 7 to 105 g C m − 2 yr − 1 (mean 23 ± 14 g C m − 2 yr − 1 ). Climatic conditions exerted a direct influence on the peat's plant composition and subsequently affected C accumulation through litter characteristics and abundance, whereas disturbances had a weak effect. Carbon accumulation was greater (31 g C m − 2 yr − 1 ) at times of wetter and warmer conditions when Sphagnum was dominant, and lower (17 g C m − 2 yr − 1 ) during periods of mixed Sphagnum and vascular plant (mainly sedges) growth under drier/unstable hydrological conditions. Future climate projections of warmer temperatures and greater annual precipitation could therefore positively influence the C sink potential of this peatland. On the other hand, increased anthropogenic pressure in the future may negatively impact the C accumulation. Our study strengthens the geographical coverage of proxy reconstructions of past hydrological variability and highlights the carbon-sink capacity of mountain bogs in a so far understudied region.

Normal prostate and cancerous prostate tissue sections were analyzed using synchrotron radiation-induced X-ray emission and X-ray absorption near-edge structure (XANES) at the X-26A microprobe beam line located at the National Synchrotron Light Source, Brookhaven National Laboratory, USA. In both measurements, a monochromatic beam of size of 16×14 μm2 was applied. Two-dimensional scans of selected areas of non-cancerous and cancerous tissue sections were performed in order to obtain the distributions of various trace element concentrations. The XANES spectra were recorded for selected points containing high concentrations of iron. These measurements were performed with the aim of determining the oxidation state of iron. It was found that the iron concentration was much higher in the cancerous sections of the analyzed tissues than in the non-cancerous sections. From the results of XANES spectra analysis, iron in cancerous prostate tissue sections mostly occurs in the +3 oxidation state. [Copyright &y& Elsevier]
