Lessons learnt from the COVID-19 pandemic: results of EAHP survey on the future crisis preparedness of hospital pharmacies

2021

Aim The present survey aimed to collect information on the lessons learnt from the COVID-19 pandemic by hospital pharmacists. It focused on the shortages of health goods and the experiences of hospitals during the first phase of the crisis. Methods A 17-question survey was conducted by EAHP, looking at the experiences of hospital pharmacists during the COVD-19 pandemic. The survey ran from 16 September to 23 December 2020. Statistical analysis included backward stepwise logistic regression (BSLR), Pearson’s χ2 test, t-test and one-way ANOVA, as appropriate; p≤0.05 was considered statistically significant. Results 1466 hospital pharmacists answered the survey fully. 58%, 63% and 69% of them …

Effect of Gold(I) on the Room-Temperature Phosphorescence of Ethynylphenanthrene.

2020

The synthesis of two series of gold(I) complexes containing the general formulae PR 3 ‐Au‐C≡C‐phenanthrene (PR 3 = PPh 3 ( 1a / 2a ), PMe 3 ( 1b / 2b ), PNaph 3 ( 1c / 2c )) or (diphos)(Au‐C≡C‐phenanthrene) 2 (diphos = 1,1‐ bis (diphenylphosphino)methane, dppm ( 1d / 2d ); 1,4‐ bis (diphenylphosphino)butane, dppb ( 1e / 2e )) have been synthesized. The two series differ on the position of the alkynyl substituent on the phenanthrene chromophore, being at the 9‐position (9‐ethynylphenanthrene) for the L1 ‐series and at the 2‐position (2‐ethynylphenanthrene) for the L2 ‐series. The compounds have been fully characterized by 1 H and 31 P NMR and IR spectroscopy, mass spectrometry and single cry…

SrP3N5O: a highly condensed layer phosphate structure solved from a nanocrystal by automated electron diffraction tomography.

2011

The oxonitridophosphate SrP(3)N(5)O has been synthesized by heating a multicomponent reactant mixture that consisted of phosphoryl triamide OP(NH(2))(3), thiophosphoryl triamide SP(NH(2))(3), SrS, and NH(4)Cl enclosed in evacuated and sealed silica-glass ampoules up to 750 °C. The compound was obtained as nanocrystalline powder with needle-shaped crystallites. The crystal structure was solved ab initio on the basis of electron diffraction data by means of automated electron diffraction tomography (ADT) and verified by Rietveld refinement with X-ray powder diffraction data. SrP(3)N(5)O crystallizes in the orthorhombic space group Pnma (no. 62) with unit-cell data of a=18.331(2), b=8.086(1), …

Surfactant-Mediated Morphology and Photocatalytic Activity of α‑Ag2WO4 Material

2018

In the present work, the morphology (hexagonal rod-like vs cuboid-like) of an α-Ag2WO4 solid-state material is manipulated by a simple controlled-precipitation method, with and without the presence of the anionic surfactant sodium dodecyl sulfate (SDS), respectively, over short reaction times. Characterization techniques, such as X-ray diffraction analysis, Rietveld refinement analysis, Fourier-transform (FT) infrared spectroscopy, FT Raman spectroscopy, UV–vis spectroscopy, transmission electron microscopy (TEM), high-resolution TEM, selected area electron diffraction, energy-dispersive X-ray spectroscopy, field emission-scanning electron microscopy (FE-SEM), and photoluminescence emission…

Photocatalytic H2 evolution from aqueous solutions of oxygenated organic compounds in the presence of C3N4/reduced graphene oxide based photocatalysts

2022

Composites of C3N4/reduced graphene oxide have been used as a cheap and promising photocatalysts for triethanolamine and ethanol photo-reforming with H2 generation in aqueous solution. The rate of H2 production over the best performing photocatalysts reached 1,415 μmol·h-1·g-1 which increases up to 57,306 in the presence of 1% of Pt. The apparent quantum efficiency of the optimal material was 7 % by using both LED and natural sunlight irradiation

Red Light Optogenetics in Neuroscience

2022

Optogenetics, a field concentrating on controlling cellular functions by means of light-activated proteins, has shown tremendous potential in neuroscience. It possesses superior spatiotemporal resolution compared to the surgical, electrical, and pharmacological methods traditionally used in studying brain function. A multitude of optogenetic tools for neuroscience have been created that, for example, enable the control of action potential generation via light-activated ion channels. Other optogenetic proteins have been used in the brain, for example, to control long-term potentiation or to ablate specific subtypes of neurons. In in vivo applications, however, the majority of optogenetic too…

Music-related motor skills in pianists - Predictors of skill acquisition in childhood and of maintenance in adulthood

2009

Background and Study Aims: Previous research on musical performance achievement has focused on the overall musical performance and on musical subskills. Two studies were conducted to identify predictors of motor skill acquisition in children pianists and of long-term development of motor skills in expert pianists in a relevant musical context. Methods: Motor skills at the piano were assessed in standardized C major scale playing. For each participant, overall temporal unevenness of note onsets was calculated as the median of the mean standard deviations of inter-onset intervals of both hands and playing directions. Study 1: Motor performance was tested in 30 piano playing children. Informat…
