Data collection ended when patients were ready for surgery, or if ephedrine was given to increase mean arterial pressure.\n\nMain Results: 21 patients had hypotension. Baseline blood pressure variability low-frequency band power (BPV LF) >8 mmHg(2) and near-infrared spectroscopy (NIRS) reduction >= 5% had high sensitivity (0.73 and 0.90, respectively) and specificity (0.78 and 0.64, respectively), and were significantly associated with the development of hypotension. Conclusions: Only NIRS and BPV Napabucasin LF Could significantly predict hypotension

“Cessation of traditional mowing management has been the main threat to fen biodiversity for many decades; shrubs and trees expand and target plant and animal species decline. In Biebrza National Park (BNP), the EU’s HKI-272 largest conservation area of alkaline fens, abandonment has affected more than 300 km(2). To combat unwanted succession, tracked mowers were developed based on snow grooming vehicles and are increasingly used in BNP and some other

European fens. While effects on bird populations seemed promising, the impact on botanical diversity remained yet unknown. We assessed the effects of this management on vegetation by comparing 12 pairs of mown and unmown plots (percentage cover recorded from 4 m(2) for all species and 25 m(2) for rare species) spread over several km(2). We found that tracked vehicles suppressed some species, this website which are likely to facilitate others by providing shelters above groundwater level (hummock mosses, tussock sedges and shrubs) and enhanced species with effective clonal spread

and high specific leaf area. An even stronger increase was observed in forbs, which share effective clonal spread and flood tolerance (high Ellenberg F value). Analysis of functional diversity indices based on all measured traits showed a decrease of functional divergence due to mowing (indicating convergence of traits) and no response of functional richness, evenness and functional dispersion. Mowing has also decreased the number of rare species. We associate these changes with the reduction of micro-topography by caterpillar tracks. Tracked mowers should therefore be avoided in those fens, in which microtopography contributes to unique botanical diversity. (C) 2013 Elsevier Ltd. All rights reserved.”
“Object. Patients with moyamoya who are younger than 2 years of age represent a therapeutic challenge because of their frequent neurological instability and concomitant anesthetic risks. The authors report their experience with pial synangiosis revascularization in this population.\n\nMethods. The authors reviewed the clinical and radiographic records of all patients with moyamoya in a consecutive series of patients under 2 years of age, who underwent cerebral revascularization surgery using pial synangiosis at a single institution.\n\nResults.
