All soundtracks were presented on an iPod through headphones. Patients and researchers were blinded to allocation until interventions were administered. State-trait anxiety was self-assessed before the intervention and
state anxiety was self-assessed again 20 minutes after the provision of the soundtrack.\n\nMain outcome measure: Spielberger State-Trait Anxiety Inventory.\n\nResults: Of 291 Transmembrane Transporters inhibitor patients assessed for eligibility, 170 patients completed the pre-intervention anxiety self-assessment and 169 completed the post-intervention assessment. Significant decreases (all P < 0.001) in anxiety level were observed among patients exposed to the electroacoustic musical composition (pre-intervention mean, 39; post-intervention mean, 34), audio field recordings (42; Prograf 35) or audio field recordings with embedded bianaural beats (43; 37) when compared with those allocated to receive simulated ED ambient noise (40; 41) or headphones only (44; 44).\n\nConclusion: In moderately anxious ED patients, state anxiety
was reduced by 10%-15% following exposure to purpose-designed sound interventions.”
“Multilayered film polycarbonate/polystyrene (PC/PS) comprising 257 layers with total thickness 125 mu m was made by coextrusion process. The nominal thickness of PC layers was 680 nm, and the nominal thickness of PS layers was 290 nm. Additionally, the control samples of PC and PS with the thickness of 125 mu m were coextruded in the same way. There was reasonably good correlation between the PC and PS layers real thickness as measured by AFM and the estimated thickness determined from the processing parameters. Significant shift of glass transition temperature is observed in multilayer film: for PS component toward higher temperature while PC still being glassy and for PC toward GSK1838705A mouse lower temperature while PS being in rubbery phase.
To investigate the amplitude and geometry of fast segmental motions, the LG-CP NMR technique under fast magic-angle spinning was used. 2D 13C?1H LG-CP spectra of PC, PS, and PC/PS 70/30 were recorded at various temperatures. Cross sections of aromatic carbons spectra show us the influence of PC on PS and vice versa. It gives us also the information about PS and PC segmental motion as a function of temperature: above the glass transition temperature of PS, the PC component of a multilayer film, although still being in glassy state, becomes more flexible.

“Several compounds present in fruits as polyphenols are able to kill or inhibit the growth of microorganisms. These proprieties are relevant mainly in tropical areas, as Amazonian region where infectious are highly prevalent. Therefore, this study investigated the antimicrobial activity of tucuma Amazonian fruit against 37 microorganisms. The potential role of oxidative metabolism imbalance was also studied as causal mechanism of antimicrobial activity.
