Introduction: Osteochondrosis (OC) is a developmental disease in horses which has a significant impact on the horse’s welfare and performance. The early disturbance in the process of endochondral ossification progresses to inflammatory and repair processes in older horses. Previously, differentially expressed genes in leukocytes of OC-affected horses have been identified. The aim of the present study is to detect age-related changes in these differentially expressed genes. Materials and Methods: The expression of OC-related genes was analysed by real-time PCR and subsequent statistical analysis (ΔΔCT) in the leukocytes of 135 Belgian Warmblood horses divided into three different age groups: 30 months (n=38). Results: Relative expression of genes of horses less than 12 months of age showed significant induction of the genes MGAT4A, PRKCG, MHCI, ApoB, ApoB3G, B4GALT6 and a significantly lower expression of the genes OAS3. Horses of 18–24 months of age, showed a significantly higher expression of the genes TBC1D9, MGAT4A, IFIH1, MHCIIa and MMP1. Horses of more than 30 months of age showed a significantly higher expression of the genes MGAT4A, HP, SECTM1 compared with their age-matched control groups. Conclusions: The study demonstrates that OC-related genes are differentially expressed in horses of different ages compared with their age-matched controls. Some of the genes may be implicated in cell signalling and differentiation as well as carbohydrate and lipid metabolism and inflammation. However, the causal relationship between the differentially expressed genes and the development and progression of the OC lesions needs to be determined. [less ▲]

Trends in the vertical distribution of ozone are reported and compared for a number of new and recently revised datasets. The amount of ozone-depleting compounds in the stratosphere (as measured by Equivalent Effective Stratospheric Chlorine – EESC) maximised in the second half of the 1990s. We therefore examine the trends in the periods before and after that peak to see if any change in trend is discernible in the ozone record. Prior to 1998, trends in the upper stratosphere (~ 45 km, 4 hPa) are found to be −5 to −10% per decade at mid-latitudes and closer to −5% per decade in the tropics. No trends are found in the mid-stratosphere (28 km, 30 hPa). Negative trends are seen in the lower stratosphere at mid-latitudes in both hemispheres and in the deep tropics. However it is hard to be categorical about the trends in the lower stratosphere for three reasons: (i) there are fewer measurements, (ii) the data quality is poorer, and (iii) the measurements in the 1990s are perturbed by aerosols from the Mt. Pinatubo eruption in 1991. These findings are similar to those reported previously even though the measurements for the two main satellite instruments (SBUV and SAGE II) and the ground-based Umkehr and ozonesonde stations have been revised. There is no sign of a continued negative trend in the upper stratosphere since 1998: instead there is a hint of an average positive trend of ~ 2% per decade in mid-latitudes and ~ 3% per decade in the tropics. The significance of these upward trends is investigated using different assumptions of the independence of the trend estimates found from different datasets. The averaged upward trends are significant if the trends derived from various datasets are assumed to be independent, but are generally not significant if the trends are not independent. This arises because many of the underlying measurement records are used in more than one merged dataset. At this point it is not possible to say which assumption is best. Including an estimate of the drift of the overall ozone observing system decreases the significance of the trends. The significance will become clearer as (i) more years are added to the observational record, (ii) further improvements are made to the historic ozone record (e.g. through algorithm development), and (iii) the data merging techniques are refined, particularly through a more rigorous treatment of uncertainties.

The CoForTips project aims at the promotion of better management of the forest of the Congo Basin by presenting to the policy makers plausible scenarios of social and ecological systems evolution. In this paper, we focused on the impact of deforestation on land tenure mutation in Central Africa. Land tenure defines the level of ownership and management experienced by the local population on defined areas (Le Roy et al., 1996). We assume that the rules acting on objects of land tenure evolve from loose land control to privatization and the ability to dispose of resources when we progress on the forest transition curve designed by Mather (1992). We demonstrate that individual land tenure increases along with the deforestation process, and continue along with the reforestation process where this one is a consequence of agricultural plantations on deforested lands. We then draw a theoretical land tenure evolution with variation of population density in relation to forest cover that could be used as an indicator of SES shifting more sensitive than the evolution of forest cover to appreciate forest transition at the SES level and predict the presence and intensity of tipping points.

Given a worldwide preference for suffixes over prefixes, why do some languages nonetheless have a macro-preference for prefixes? In this talk, we show that Ancient Egyptian-Coptic (Afroasiatic) shows a long-term diachronic macro-change from mixed suffixing-prefixing to an overwhel¬ming preference for prefixing. We argue that each of the micro-changes implicated in this macro-change are better understood in terms of regular changes at the level of individual constructions, via, e.g., grammaticalization, rather than in terms of a broad Sapirian ‘drift.’ Crucially, it is the particular constellation of structural features of the language at a particular moment in time, together with regular mechanisms of language change, that give rise to the cross-linguistically unusual ‘macro-preference’ of the language.

Analysis of national health insurance accounts in the Democratic Republic of Congo (DRC) clearly shows the importance of international sanitary aid, particularly for the funding of general referral hospitals, the management of inpatients with AIDS, administration of health zones and funding of preventive care providers. It The targeted changes described in this article could possibly optimize the efficiency of international aid for the DRC population, mainly for disorders considered to be a health care priority (i.e. malaria, AIDS, tuberculosis) as well as in the fight against malnutrition. Recommendations target the implementation of procedures for control of food chain security, changes in lifestyle and dietary habits of the population but also comprise extensive restructuring of the health care administration. A dramatic change of the structure in charge of drug distribution as well as eradication of the transfer of part of public health structure income to public health administrative personnel could result in the allocation of significant funds to the fight against the most important diseases. Better collaboration between the various departments in charge of health care professional training, together with enhanced responsibility of health care personnel is essential. Independent and respected non-governmental organizations should be involved in an audit process, targeting all aspects of the current DRC health system. Eventually, in an equal opportunity perspective, taking into consideration the very high degree of poverty of DRC inhabitants, implementation of health insurance programmes, use of generic drugs and generalization of micro-credit initiatives should also be implemented.

Drier condition during the growing season have been predicted in the future. It has been suggested that diverse forest could maintain productivity and provide better ecosystem services under stress condition such as drought. However, those studies focused mainly on mature forest and little known about young forest. Oak and beech are the important species in European forestry, and may face a strong challenge in the future. Drought effects on young ( ̴5yr) oak and beech saplings in monoculture and mixed with other species are not known. Moreover, single studies evaluating both above- and below-ground ecosystem response to drought are scarce. A two-year manipulative field experiment has been planned to answer the following questions. (i) Can species mixtures improve oak and beech sapling performances under drought conditions? (ii) What are the mechanisms underlying ecosystem functioning and sapling performance in mixed species stands subjected to drought? A 3m × 3m rainout shelter will be placed only in growing season in Zedelgem sites of FORBIO experimental platform (http://www.treedivbelgium.ugent.be/pl_forbio.html). Tree diversity vary from 1 to 4 species and about 50% of precipitation will be taken off. Both aboveground sapling performance and belowground microbial properties and biogeochemical processes will be investigated. We will present the design of the experimental tree species diversity plantation of Zedelgem site, the setting of the drought experiment and planned analysis [less ▲]
