Duplicate publication can introduce significant bias into a meta-analysis if studies are inadvertently included more than once. Many studies are published in more than one journal to maximize readership and impact of the study findings. Inclusion of multiple publications of the same study within a meta-analysis affords inappropriate weight to the duplicated data if reports of the same study are not linked together. As studies which have positive findings are more likely to be published in multiple journals this leads to a potential overestimate of the benefits of an intervention. Recent advances in immunosuppression strategies following liver transplantation have led to many studies investigating immunosuppressive regimes including immunosuppression monotherapy. In this letter we focus on a recently published meta-analysis by Lan et al investigating studies assessing immunosuppression monotherapy for liver transplantation. The authors claim to have identified fourteen separate randomised studies investigating immunosuppression monotherapy. Seven of the references appear to relate to only three studies which have been subject to duplicate publication. Several similarities can be identified in each of the duplicate publications including similar authorship, identical immunosuppression regimes, identical dates of enrolment and citation of the original publication in the subsequent manuscripts. We discuss the evidence of the duplicate publication inclusion in the meta-analysis.

We report a far-infrared absorption study of internal transitions of shallow Be acceptors in both bulk GaAs and a series of δ-doped GaAs/AlAs multiple quantum well samples with well thicknesses of 20,15 and 10 nm. Low temperature far-infrared absorp-tion measurements clearly show three principal absorption lines due to transitions of Be-acceptor states from the ground state to the first three odd-parity excited states,respec-tively. Using a variational principle,the 2p-1s transition energies of quantum confined Be acceptors are calculated as a function of the well width. It is found that the theoretical calculation of the 2pz → 1s transitions is in good agreement with the D-like line experi-mental data.

Background: There is considerable interest in implementing mobile scanning technology for on-farm body composition analysis on live *** experiments evaluated the use of dual energy X-ray absorptiometry(DXA) as an accurate method of total body fat measurement in live ***: In Exp.1,visceral and whole body fat analysis was undertaken in sheep with body condition scores(BCS)in the range 2 to 3.25(scale 1: thin to 5: fat).The relationship of BCS was moderately correlated with visceral fat depot mass(r = 0.59,P 0.05,n = 9).There was a moderate correlation between DXA body fat and BCS(r = 0.70,P < 0.01,n = 17),and DXA body fat was highly correlated with chemical body fat(r = 0.81,P < 0.001,n = 9).In Exp.3,a series of five DXA scans,at 8-week intervals,was performed on growing sheep over a 32-week *** average BCS ranged from 2.39 ± 0.07(S.E.M.) to 3.05 ± 0.11 and the DXA body fat(%) ranged from 16.8 ± 0.8 to 24.2 ± *** was a moderate correlation between DXA body fat and BCS over the 32 weeks(r = 0.61,P < 0.001,n = 24).Conclusions: Overall,these experiments indicated that there was good agreement between BCS,DXA and chemical analysis for measuring total body fat in sheep,and that DXA scanning is a valid method for longitudinal measurement of total body fat in live sheep.

A near-term strategy to reduce emissions from rail vehicles,as a path to full electrification for maximal decarbonisation,is to partially electrify a route,with the remainder of the route requiring an additional self-powered traction *** rail vehicles are usually powered by a diesel engine when not operating on electrified track and are referred to as bi-mode *** paper analyses the benefits of discontinuous electrification compared to continuous electrification using the CO_(2)estimates from a validated high-fidelity bi-mode(diesel-electric)rail vehicle *** analysis shows that 50%discontinuous electrification provides a maximum of 54%reduction in operational CO_(2)emissions when compared to the same length of continuously electrified *** highest emissions savings occurred when leaving train stations where vehicles must accelerate quickly to line *** results were used to develop a linear regression model for fast estimation of CO_(2)emissions from diesel running and electrification *** model was able to estimate the CO_(2)emissions from a route to within 10%of that given by the high-fidelity ***,additional considerations such as cost and the embodied CO_(2)in electrification infrastructure were analysed to provide a comparison between continuous and discontinuous *** electrification can cost up to 56%less per reduction in lifetime emissions than continuous electrification and can save up to 2.3 times more lifetime CO_(2)per distance electrified.

After a long silence, Lake Vui on Ambae Island burst into spectacular life on November 28, 2005, disrupting the lives of the 10,000 inhabitants on this sleepy tropical island in the SW Pacific. ＂Surtseyan-style＂ explosions burst through the Island＇s summit lake waters, forming a new tuff-cone, and threatening to form deadly lahars or volcanic floods. Such eruptions are rarely well observed, and these fleeting opportunities provide a chance to match volcanic processes with rock-sequences common in the geologic record...

The enemies release hypothesis proposes that exotic species can become in- vasive by escaping from predators and parasites in their novel environment. Agrawal et al. （Enemy release？ An experiment with congeneric plant pairs and diverse above- and below-ground enemies. Ecology, 86, 2979-2989） proposed that areas or times in which damage to introduced species is low provide opportunities for the invasion of native habitat. We tested whether ornamental settings may provide areas with low levels of herbivory for trees and shrubs, potentially facilitating invasion success. First, we compared levels of leaf herbivory among native and exotic species in ornamental and natural settings in Cincinnati, Ohio, United States. In the second study, we compared levels of herbivory for invasive and noninvasive exotic species between natural and ornamental settings. We found lower levels of leaf damage for exotic species than for native species; however, we found no differences in the amount of leaf damage suffered in ornamental or natural settings. Our results do not provide any evidence that ornamental settings afford additional release from herbivory for exotic plant species.

The term ’Health Service’ signifies the whole system of service for the maintenance and restoration of health. The practice of ndicine and the practice of dentistry are co-ordinate divisions of health seryice. Dentistry has been traditionally a means of repairing and perfecting the mechanism of mastication, inducing oral comfort, correcting maxillary and palatal deformities, maintaining normal, vocal enunciation and retaining or restoring facial comeliness. Dentistry has become and is now primarily oral health service. Excep-
