AbstractAbstractThe electrolytic deposition of nickel is demonstrated using a solution the metal chloride salt separately in either urea or ethylene glycol/choline based ionic liquid. It shown that kinetics and thermodynamics differ from aqueous processes these result different deposit morphologies. also for first time bright coatings can be obtained liquid systems by adding various brightening agents deposits put directly onto substrates such as aluminium without prior treatment. The...
In this paper, we describe the first example of a sustained galvanic coating deposited on surface from non-aqueous liquid. We present characterization electroless silver deposits copper substrates solution Ag+ ions in an ionic liquid based choline chloride (ChCl) eutectic. Through study these and mechanism formation using acoustic impedance spectroscopy (QCM), probe microscopy (AFM) electron (SEM/EDX), demonstrate that growth deposit is facilitated by porous nature silver. This contrast to...
Huntington9s disease (HD) is a fatal autosomal dominant neurodegenerative involving progressive motor, cognitive and behavioural decline, leading to death approximately 20 years after motor onset. The characterised pathologically by an early striatal neuronal cell loss atrophy, which has provided the rationale for first clinical trials of neural repair using fetal transplantation. Between 2000 2003, 'NEST-UK' consortium carried out bilateral transplants human tissue in five HD patients. This...

Gas chromatographic analysis of the hydrocarbons environmental samples often reveals that unresolved complex mixtures (UCMs) or gas "humps" aliphatic and aromatic are most abundantyet little consideration seems to have been given possible toxicological impacts hydrocarbon "humps". Here we show, using a well-accepted bioassay, monoaromatic components UCM from crude oil elicit sublethal toxic response in typical marine pollution indicator organism (the mussel, Mytilus edulis). Furthermore,...
We have studied the deposition of Zn metal onto a polished gold-coated quartz crystal with in situ tapping-mode atomic force microscopy (AFM), while simultaneously recording chronoamperometric and acoustic impedance microbalance (QCM) measurements. are able to demonstrate good correlation between three techniques. Modeling data recorded for initial nucleation process same experiment suggests that initially occurred via progressive mechanism. Crystallites different sizes were clearly visible...
Abstract A collaborative study was conducted on the Biosense amnesic shellfish poisoning (ASP) enzyme-linked immunosorbent assay (ELISA) for determination of domoic acid (DA) toxins in order to obtain interlaboratory validation data method. In addition, a method comparison performed evaluate ASP ELISA as an alternative current liquid chromatography (LC) reference DA determination. The material comprised 16 samples, including blue mussels, Pacific oysters, and king scallops, spiked with...
Here we describe the electrolytic deposition of a range metallic coatings, alloys and composites from room temperature ionic liquids that have low environmental impact/toxicity, are inexpensive easy to handle. We show some these systems can be considered as "drop-in" replacement technologies for existing aqueous processes currently utilize strong inorganic acids highly toxic reagents.
The acute toxicity of the oil dispersant Corexit 9527 reported in literature is highly variable. No peer-reviewed data exist for Superdispersant-25 (SD-25). This study compares two dispersants to a range marine species representing different phyla occupying wide niches: sediment-dwelling amphipod Corophium volutator (Pallas), common mussel Mytilus edulis (L.), symbiotic snakelocks anemone Anemonia viridis (Forskål), and seagrass Zostera marina (L.). Organisms were exposed static...
Exposure of marine mussels (Mytilus edulis) to an unresolved complex mixture (UCM) aromatic hydrocarbons isolated from a crude oil has been shown reduce their feeding rate by 40%. The present study was undertaken determine whether UCMs bioaccumulated in the field are also toxic. derived polluted sites increased when they were placed clean water, pointing loss toxic agents tissues. At end depuration period, water which oil-polluted site had held contained UCM. Steam-distillation extracts...
Summary Due to the cost and complexity of sampling biological communities, surrogate measures or concentrations toxic contaminants are often used indicate environmental impacts. Such indicators can be powerful tools, but their effectiveness requires evaluation. Mussels widely as bioindicators contamination. For example, physiological measurements on live mussels form basis scope for growth (SFG), an integrated indicator stress. However, SFG community level effects has rarely been tested in...
We report the first dynamic in situ electrochemical neutron reflectivity (NR) measurements on electroactive films. By using a boxcar integration strategy within cyclic voltammetric experiment, it is possible to acquire data associated with narrow, defined windows of potential. Accumulation from repetitive cycles allows one build up potential- (time-) resolved profiles. The effective time resolution now order seconds, as compared ca. 1 h conventional methodology, making NR practical technique...
Time-resolved specular neutron reflectivity measurements are presented and interpreted for electroactive polyvinylferrocene (PVF) films subject to potentiodynamic electrochemical control. New data acquisition methodology allows an effective measurement time scale on the order of seconds, which is improvement over conventional by 2 3 orders magnitude. Reflectivity profiles were obtained PVF exposed aqueous 0.1 M NaClO4 in thermodynamically permselective, with contrast variation via H2O D2O....

For patients with incurable neurodegenerative disorders such as Huntington's (HD) and Parkinson's disease, cell transplantation has been explored a potential treatment option. Here, we present the first clinicopathological study of patient HD in receipt cell-suspension striatal allografts who took part NEST-UK multicenter clinical trial. Using various immunohistochemical techniques, found discrepancy survival grafted projection neurons respect to interneurons well major ongoing inflammatory...
Abstract A recent study has shown that some monoaromatic hydrocarbon constituents of the so-called unresolved complex mixtures (UCMs) or gas chromatographic humps, which are widespread in marine environment, toxic to mussel Mytilus edulis. Here we describe synthesis and toxicological assessment 6-cyclohexyltetralin, 7-cyclohexyl-1-methyltetralin, 7-cyclohexyl-1-n-propyltetralin, contain structural features consistent with UCM hydrocarbons. The compounds were all M. edulis when measured assay...

ABSTRACT Amphipods are widely used in both acute and chronic (sub-lethal) sediment tests. Acute tests provide relatively rapid results, but may fail to detect moderately toxic contaminants that bound the sediment, whereas life-cycle rarely performed as they time consuming expensive. Observations during testing of oil-contaminated suggested there be a link between behavior marine amphipod Corophium volutator reduction growth rate. Behavior were with six individual amphipods per treatment...
