Crop associations can have beneficial effects on the control of insect pests. This study was conducted in the Shandong province (China) to assess the impact of potatoes and peas association on the populations of aphids and aphidophagous beneficials. Observations on potato plants and trapping were performed. During the season, the degree of infestation didn’t differ significantly between the association and the pure stand. However, the aphidophagous beneficials were more abundant in the association comparing to the pure stand. Trapping results give a more general idea about the richness and diversity of natural enemies present in the environment. Aphidius gifuensis (Ashmead) and Aphelinus abdominalis Dalman are the most abundant parasitoids. Among predators, Propylea japonica (Thunberg) and Harmonia axyridis (Pallas) are prevalent. Few hoverflies and lacewings were trapped. Results from the observations on plants do not support the resource concentration hypothesis. However, the enemy hypothesis was confirmed for the aphidophagous beneficials. Therefore, this association can have a beneficial effect on the control of aphid populations. [less ▲]

The purpose of this study was to evaluate the bacterial diversity and its evolution during storage of fresh beef, depending on its origin, packaging and storage temperature, by using a metagenomic approach. Metagenomic analyzes revealed that the origin, atmosphere and temperature conditions influenced the selection of the predominant flora. Vacuum-packaged British samples presented higher concentrations of Lactobacillus algidus at the begging of the experiment than Belgian samples. Furthermore, the development of Lactobacillus algidus was favored in British and Belgian samples preserved under vacuum at −1 °C, while a predominance of Lactococcus piscium was observed for samples stored at +4 °C. These microorganisms have already been isolated from beef, but taking into account that the knowledge about these two species is currently limited, it is still not possible to state if the conservability of the tested samples was influenced by the presence of these bacteria. Moreover, storage under modified atmosphere favored the development of Leuconostoc gasicomitatum in both British and Belgian samples. This specie is often associated with spoilage of cold-stored modified-atmosphere-packaged (MAP) nutrient-rich foods. This result can partially explain the short shelf-life of the samples once they are stored under this condition. Metagenomics showed to be a useful tool to study the microbial population of a complex matrix since some of the identified genera could not have grown or have grown slowly in culture media commonly used. In addition, it helped to clarify the evolution of the bacterial ecosystem associated to meat during its storage. [less ▲]

Initiating Damage Control Resuscitation (DCR) as early as possible in severe trauma patients with Early Acute Coagulopathy of Trauma (EACT) is pivotal for patients’ survival. DCR that combines damage control surgery, permissive hypotension and early aggressive haemostatic resuscitation (EAHR), however implies among other things surgical and transfusion resources that are available 24H/7d in trauma centres but cannot be offered, for economic reasons, in emergency units from general hospitals. In Belgium, in the absence of trauma centres, trauma patients are referred to general hospitals. 50 trauma patients per year are so referred to our emergency unit “diluted” in more than 65,000 non-trauma cases. This “dilution” prohibits maintaining the necessary organisation for immediate initiation of DCR preventing trauma patients with EACT to be optimally managed. In order to allow DCR (and EAHR) in severe trauma patients with EACT at hospital entry, we have developed an easy-to-measure purely clinical score (the TICCS) aiming at “flagging” patients with EACT on the site of injury. In contrast to currently available trauma scoring systems, our score can be calculated by paramedics in less than 1 min and then communicated to the hospital allowing taking the necessary organisational measures before patient’s arrival. “Flagging” trauma patients with EACT on the site of injury and activating then the necessary resources for an immediate DCR at patient’s hospital entry could allow saving around 45  minutes in the initiation of DCR compared to the current trauma patients’ management in our emergency unit. A prospective single-centre non-comparative non-interventional open study has been designed to validate, in approximately 100 trauma patients, the correlation between TICCS evaluated on the site of injury and thromboelastometry using TEG-ROTEM® made on a whole blood sample taken at the latest 30 min after patient’s arrival in the resuscitation room.

Doxycycline (DOXY) is associated with left ventricular (LV) dysfunction in calves in accidental overdose but not in experimental models when evaluated with classical and Doppler echocardiography. Two-dimensional-speckle tracking (2DST) is used to evaluate LV dysfunction in numerous species but not in cattle. The aim of this study was to evaluate the cardiotoxic effects of an experimental overdose of DOXY using 2DST in calves. Ten healthy male Holstein calves. Group 1: 5 calves (mean age 58.0 +/- 16.3 days; mean body weight 72.2 +/- 13.0 kg) received 25 mg/kg of DOXY orally for 5 days. Group 2: 5 calves (mean age 56.4 +/- 15.7 days; mean body weight 73.4 +/- 7.0 kg) received a placebo. Electrocardiography (ECG) and 2DST echocardiography were performed at day 0 and day 8. ECG tracings were analysed for occurrence of arrhythmias. 2DST measurements included global and segmental, peak values for radial and circumferential strains (SR, SC), strain rates (SrR, SrC), rotation (Rot), rotation rates (RotR) and radial displacement (DR). All calves completed the study. ECG recordings were unremarkable in both groups. Heart rate was neither significantly different between groups nor before and after treatment. LV systolic function was affected in calves receiving an overdose of DOXY as shown by a significant decrease of segmental SR (P < 0.05), SC (P < 0.05) and DR (P < 0.05) in treated calves compared to the placebo group in several segments. The SrC in early diastole was also significantly decreased in 1 segment (<0.05). In calves, DOXY overdose induces a LV dysfunction in systole, and to a lesser extent, in diastole. A better comprehension of the pathophysiology involved in the DOXY overdose will help in the treatment of accidental cases. [less ▲]

The surface mass balance (SMB) of the Antarctic Ice Sheet cannot be reliably deduced from global climate models (GCMs), both because their spatial resolution is insufficient and because their physics are not adapted for cold and snow-covered regions. By contrast, regional climate models (RCMs) adapted for polar regions can physically and dynamically downscale SMB components over the ice sheet using large-scale forcing at their boundaries. Polar-oriented RCMs require appropriate GCM fields for forcing because the response of the cryosphere to a warming climate is dependent on its initial state and is not linear with respect to temperature increase. In this context, we evaluate the current climate in 41 climate models from the Coupled Model Intercomparison Project Phase 5 (CMIP5) data set over Antarctica by focusing on forcing fields which may have the greatest impact on SMB components simulated by RCMs. Our inter-comparison includes six reanalyses, among which ERA-Interim reanalysis is chosen as a reference over 1979–2014. Model efficiency is assessed taking into account the multi-decadal variability of the fields over the 1850–1980 period. We show that fewer than 10 CMIP5 models show reasonable biases compared to ERA-Interim, among which ACCESS1-3 is the most pertinent choice for forcing RCMs over Antarctica, followed by ACCESS1-0, CESM1-BGC, CESM1-CAM5, NorESM1-M, CCSM4 and EC-EARTH. Finally, climate change over the Southern Ocean in CMIP5 is less sensitive to the global warming signal than it is to the present-day simulated sea-ice extent and to the feedback between sea-ice decrease and air temperature increase around Antarctica.

During the last decades, the production of endocrine disrupting chemicals reached such elevated levels that they are now spread all over the environment. Endocrine disrupting chemicals are known to be very slowly degraded, decreasing the environmental quality and causing ecological risks. Marine mammals inhabiting polluted environments accumulate high quantities of these chemicals, and are good indicators of marine pollution Thirteen major organochloride pollutants (known from literature to contaminate north sea porpoise) were chosen in this study – o,p’-DDD; p,p’-DDD; p,p’-DDE; o,p’-DDT; p,p’-DDT; HCB; α-HCH; β-HCH; γ-HCH; δ-HCH; PCB 138; PCB 153 and PCB 180. The thirteen chemicals were tested individually and in mixtures by the use of report gene expression assays. The MCF7-ERE cells used in the assays were originated from MCF7 human mammary tumor cells transfected with the ERE-luciferase reporter system. Preliminary results suggest that o,p’-DDD; p,p’-DDD; o,p’-DDT; HCB; β-HCH; δ-HCH; PCB 138 and PCB 180 are able to stimulate the luciferase expression of MCF7-ERE cells when they are present individually or in mixtures. No synergism was observed within mixtures. When MCF7-ERE cells were exposed to the chemicals and 17β-oestradiol simultaneously, p,p’-DDE; α-HCH; PCB 138 and PCB 180 could raise the luciferase expression in comparison to the exposition of 17β-oestradiol alone; on the other hand, o,p’-DDD; p,p’-DDT; HCB; β-HCH; γ-HCH and δ-HCH seem to inhibit the luciferase expression at low doses. In the next step, the pollutants will be searched and quantified in the blubber tissue of porpoises by use of gas chromatography-mass spectrometry. The blubber tissue samples will also have their endocrine disrupting effects characterized. This work is ongoing and It is expected a relevant level of these compounds to be found in the samples. Conversely, their endocrine disrupting effects and how they act in agonist, antagonist ways are subject that still needs to be studied. [less ▲]

The expanding-contracting polar cap paradigm relates the dayside and nightside rates of magnetic reconnection to changes in the size of the ionospheric polar cap, the amount of magnetic flux in the magnetotail lobes, and the excitation of ionospheric and magnetospheric plasma convection. Expansions of the polar cap are the consequence of dayside reconnection, the merging of interplanetary magnetic flux with the terrestrial dipole to increase the proportion of the dipole that is open. Contractions of the polar cap are caused by magnetic reconnection in the magnetotail at a distant neutral (or X-) line (DXL) and near-Earth neutral line (NEXL), the latter especially during substorms, to reduce the open flux in the magnetosphere. There is debate surrounding the proportion of flux closure provided by the DXL and NEXL, and hence whether substorms dominate the nightside contribution to ionospheric and magnetospheric convection. This study utilizes a 7-day interval of auroral observations from the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) satellite and convection measurements by the Super Dual Auroral Radar Network (SuperDARN) to quantify the nightside rates of reconnection during substorm and non-substorm periods and hence investigate DXL and NEXL flux closure.
