Because of the progressive loss of nigro-striatal dopaminergic terminals in Parkinson’s disease (PD), in vivo quantitative imaging of dopamine (DA) containing neurons in animal models of PD is of critical importance in the pre-clinical evaluation of highly awaited disease-modifying therapies. Among existing methods, the high sensitivity of positron emission tomography (PET) is attractive to achieve that goal. The aim of this study was to perform a quantitative comparison of brain images obtained in 6-hydroxydopamine (6-OHDA) lesioned rats using two dopaminergic PET radiotracers, namely [18F]fluoro-3,4-dihydroxyphenyl-L-alanine ([18F]FDOPA) and 6-[18F]fluoro-L-m-tyrosine ([18F]FMT). Because the imaging signal is theoretically less contaminated by metabolites, we hypothesized that the latter would show stronger relationship with behavioural and post-mortem measures of striatal dopaminergic deficiency. We used a within-subject design to measure striatal [18F]FMT and [18F]FDOPA uptake in eight partially lesioned, eight fully lesioned and ten sham-treated rats. Animals were pretreated with an L-aromatic amino acid decarboxylase (AADC) inhibitor. A catechol-O-methyl transferase inhibitor was also given before [18F]FDOPA PET. Quantitative estimates of striatal uptake were computed using conventional graphical Patlak method. Striatal dopaminergic deficiencies were measured with apomorphine-induced rotations and post-mortem striatal DA content. We observed a strong relationship between [18F]FMT and [18F]FDOPA estimates of decreased uptake in the denervated striatum using the tissue-derived uptake rate constant Kc. However, only [18F]FMT Kc succeeded to discriminate between the partial and the full 6-OHDA lesion and correlated well with the post-mortem striatal DA content. This study indicates that the [18F]FMT could be more sensitive, with respect of [18F]FDOPA, to investigate DA terminals loss in 6-OHDA rats, and open the way to in vivo AADC activity targeting in future investigations on progressive PD models.

Urban explorers have for some time been producing informal iconographic and textual records of manmade structures which because of being abandoned or inaccessible for the general public, are not usually in the public eye and are often in a state of deterioration and in danger of being destroyed. This interdisciplinary research which connects the fields of architecture, history, conservation, and digital humanities, looks into the materials recorded by the urban exploration (urbex) community and investigates their potential for the protection and documentation of decaying or demolished abandoned architectural heritage sites. For the management and dissemination of heritage information for the abandoned sites, more specifically, the recently demolished Château de Noisy, a famous urbex destination in Belgium, this study explores and builds upon the existing digital resources and looks into various tools and techniques to compile, curate and present this data to narrate the story of abandoned heritage sites. Additionally, through visualisation of data collected, cleaned, and compiled using the Flickr application programming interface (Flickr API) and Python, the changes in the urbex community’s activity since their debut on Flickr are observed. This research shows the value of the existing urbex digital data for documentation and potential conservation of abandoned heritage sites and demonstrates how a mindful digital narration of even a demolished heritage site can create an engaging and immersive experience which records and preserves the heritage and its story. Additionally, it can raise public awareness which in the case of deteriorating abandoned sites can lead to their potential revival. [less ▲]

En physiologie de la reproduction, il est bien établi que les hormones glycoprotéiques hypophysaires LH (hormone lutéinisante) et FSH régulent de concert la production de stéroïdes sexuels (indispensables à la virilisation et à la féminisation) ainsi que la gamétogenèse (spermatogenèse chez l’homme et folliculogenèse chez la femme). La sécrétion des gonadotrophines hypophysaires est à son tour stimulée par quelque 1.500 neurones hypothalamiques à GnRH (gonadotrophin releasing hormone) et inhibée par la GnIH (gonadotrophin nhibitory hormone), récemment identifiée (1). En amont de la GnRH, un ensemble de neuropeptides hypothalamiques tels que les kisspeptines, la neuroquinine B, la dinorphine, la leptine, etc., modulent sa sécrétion (Figure 1). Ces neuropeptides intègrent les différents signaux internes et de l’environnement, nécessaires à la puberté et, par la suite, à la reproduction. En corollaire de ces données physiologiques, les patients porteurs de mutations invalidant les gènes de la GnRH, des neuropeptides décrits et de leurs récepteurs souffrent d’un hypogonadisme hypogonadotrope. Ces patients présentent un déficit plus ou moins sévère de la sécrétion combinée de LH et de FSH (2, 3). Il a fallu attendre des observations rares, telles que des mutations de la sous-unité beta (β) de l’hormone lutéinisante, pour comprendre la contribution spécifique et isolée de cette hormone à la reproduction. Dans cet article, nous synthétisons les données historiques et récentes sur la déficience en hormone lutéinisante et ses conséquences sur la reproduction. [less ▲]

From 2006 to 2012, the port of Cotonou improves its performance thanks to the Millennium Challenge Account program, through modernization of port facilities and management systems. But the project not concerns transport corridors and hinterland access. However, no port can develop without its links with its hinterland. That’s why we analyse the issues relating to the hinterland transport development with respect to the with interconnected rail network of West African countries. This network project allows us to build up a multimodal/intermodal transport network from and to the port of Cotonou since inland terminals may have an important role in enlarging port market areas through enhancing hinterland penetration capacity. Our findings show that if two rail-road terminals are located, one in Dosso and the other one in Parakou, it will allow a saving of about 112 million euro, promote local economies and sustainability.

We analyze the incentives of internet service providers (ISPs) to break net neutrality by excluding competing one-way essential complements, i.e. internet applications competing with their own products. A typical example is the exclusion of VoIP applications by telecom companies offering internet and voice services. A monopoly ISP may want to exclude a competing internet app if it is of inferior quality and the ISP cannot ask for a surcharge for its use. Competition between ISPs never leads to full app exclusion but it may lead to a fragmented internet where only one ISP offers the application. We show that, both in monopoly and duopoly, prohibiting the exclusion of the app and surcharges for its use does not always improve welfare. [less ▲]

Ecomorphology concerns the study of the relationships between functional design and the environmental constraints acting on organisms. It aims to understand how the morphological variations among species can be related to environmental factors and impact fitness. Having a large diversity both in their morphology and ecology, the cetacean taxa appears to be the ideal taxa to tackle the relationships between the locomotor system and way of life. Different studies have already showed that the number and shape of vertebrae in different cetaceans can reflect the stiffness of the body and consequently can impact their swimming mode. The aim of this study is to establish relationships between characteristics of the vertebral column of different cetaceans and their ecology. Meristic and morphometric data were collected on the vertebrae (centrum lengths, heights and widths, neural spine heights and transverse processes lengths) of species of odontocetes housed in different Natural History Museums in the world (AM-ULg, RBINS, MNHN, SMNS, NRM, Queensland, PEM, Iziko). Preliminary results show clear morphological variations between species at the level of the number and sizes of vertebrae. There is a clear relationship between body size and number of vertebrae except in Delphinidae. This family has an important higher vertebral count. These differences should be related to different swimming modes and reflect the different ecological behaviours of the studied cetaceans. [less ▲]

To introduce this special issue we explore the conceptual and practical synergies between the social economy and sustainable development. New empirical evidence is presented on the emergence of these two research fields and the increasing combination of these fields in the literature. Several avenues through which social enterprises can contribute to the transition towards sustainable development are then identified. This is followed by a discussion of how and why the combination can be particularly fruitful both for the social economy and for sustainability transition movements. We also highlight some important challenges facing the social economy with regard to its contribution to sustainable development. Finally we introduce the papers that constitute this special issue and show how they contribute, individually and collectively, to a better understanding of the increasing linkage between the social economy and sustainable development.
