MethOxyfluraNe in InTerventiOnal Radiology (MONITOR): A randomised controlled trial.

Introduction: Procedural sedation and pain management in interventional radiology (IR) are of critical importance to successful outcomes but remain under-researched. Methoxyflurane has been previously used in some minor procedures with several advantages including rapid onset and offset and a good safety profile. The purpose of this study was to evaluate methoxyflurane for procedures in IR.

Falls risk factor assessment and secondary prevention in the older old.

Aims: Falls are common in 80-plus year-olds and there is evidence available in terms of risk factors and prevention measures. We aimed to review falls risk factor assessment and secondary prevention strategies in patients in this age group presenting acutely to services other than older adult health services at Waitemata District Health Board.

Methods: We retrospectively reviewed electronic hospital records of those >80 years presenting to acute services with a primary or secondary diagnosis of a fall, or fall-related injury.

Continuous Monitoring via Tethered Electroencephalography of Spontaneous Recurrent Seizures in Mice.

We describe here a simple, cost-effective apparatus for continuous tethered electroencephalographic (EEG) monitoring of spontaneous recurrent seizures in mice. We used a small, low torque slip ring as an EEG commutator, mounted the slip ring onto a standard mouse cage and connected rotary wires of the slip ring directly to animal's implanted headset. Modifications were made in the cage to allow for a convenient installation of the slip ring and accommodation of animal ambient activity.

Gradual modification of ITO particle's crystal structure and optical properties by pulsed UV laser irradiation in a free liquid jet.

Indium tin oxide (ITO) particle coatings are known for high transparency in the visible, good conductive properties and near-infrared absorption. These properties depend on ITO particle's stoichiometric composition, defects and size. Here we present a method to gradually change ITO particle's optical properties by a simple and controlled laser irradiation process.

Mixed-Metal Tungsten Oxide Photoanode Materials Made by Pulsed-Laser in Liquids Synthesis.

Globally scalable sunlight-driven devices that convert solar energy into storable fuels will require efficient light absorbers that are made of non-precious elements. Suitable photoanode materials are yet to be discovered. Here we utilised the timesaving nature of pulsed-laser-in-liquids synthesis and prepared a series of neat and mixed-metal tungsten oxide photoanode materials to investigate the effect of ad-metals on optical and photocurrent generation properties.

Germanium Sub-Microspheres Synthesized by Picosecond Pulsed Laser Melting in Liquids: Educt Size Effects.

Pulsed laser melting in liquid (PLML) has emerged as a facile approach to synthesize submicron spheres (SMSs) for various applications. Typically lasers with long pulse durations in the nanosecond regime are used. However, recent findings show that during melting the energy absorbed by the particle will be dissipated promptly after laser-matter interaction following the temperature decrease within tens of nanoseconds and hence limiting the efficiency of longer pulse widths.

Plasmon assisted 3D microstructuring of gold nanoparticle-doped polymers.

3D laser lithography of a negative photopolymer (zirconium/silicon hybrid solgel SZ2080) doped with gold nanoparticles (Au NPs) is performed with a 515 nm and 300 fs laser system and the effect of doping is explored. By varying the laser-generated Au NP doping concentration from 4.8 · 10(-6) wt% to 9.

Inclusion of supported gold nanoparticles into their semiconductor support.

Supported particles are easily accessible as standard materials used in heterogeneous catalysis and photocatalysis. This article addresses our exemplary studies on the integration of supported nanoparticles into their solid support, namely gold nanoparticles into zinc oxide sub-micrometer spheres, by energy controlled pulsed laser melting in a free liquid jet. This one-step, continuous flow-through processing route reverses the educt's structure, converting the ligand-free surface adsorbate into a spherical subsurface solid inclusion within its former support.

Effects of neonatal hypoxic-ischemic episodes on late seizure outcomes in C57 black mice.

We examined brain injury and seizures in adult C57 black mice (C57/BL6) that underwent neonatal hypoxic-ischemic (HI) episodes. Mouse pups of 7 days-old underwent a ligation of the right common carotid artery and a subsequent hypoxic challenge (8% O2 for 45min). Post-HI mice were implanted with intracranial electrodes at 2-3 months of age, subjected to behavioral/EEG recordings and hippocampal electrical stimulation in next several months and then euthanized for brain histological assessments at ages of 11-12 months.

Factors influencing total carbon dioxide concentrations in plasma of thoroughbred and standardbred racehorses.

Horse racing authorities impose a limit on the concentration of plasma 'total carbon dioxide' (TCO2), typically 36 mM with action taken above 37 mM, as measured by an electrochemical gas analyzer. It is of interest to understand the distribution of TCO2 in a 'normal' population of racehorses and determine probabilities of members of this population exceeding these current regulatory and action limits. TCO2 levels in equine plasma samples have been modelled for 12 months (2011-2012) of thoroughbred (3076 measurements) and standardbred (3788 measurements) data in Australia.
