Article Reference Transdifferentiation of macrophages into fibroblasts as a result of Schistosoma mansoni infection.
The possibility of transdifferentiation of macrophages into fibroblasts which could be at the origin of fibrotic tissue in schistosome-infected mice was studied using immunocytochemical techniques. Macrophage cell samples extracted from the peritoneal cavity of schistosome-infected mice were fractionated on a Percoll gradient. The cultures were purified by treatment with a trypsin solution to eliminate any fibroblasts possibly collected along with the macrophages. Immunocytochemical methods were then used to characterize the cells at differentpoints in time. The fibroblastic property of the morphologically transformed cells was confirmed by their positive labeling with the anti-procollagen antibody. However, these cells still possessed the mac-1 and mac-2 antigens which characterize the monomacrophage line.

Article Reference A study of peritoneal cells from healthy and Schistosoma mansoni-infected mice with special reference to myofibroblasts arising in culture.
Adherent, trypsin-resistant, peritoneal cells from mice with chronic schistosomiasis mansoni, and from control mice, were cultivated in vitro up to 20 days. Fibroblasts regularly appeared, about 6 days after seeding, in cultures ofthe manyfold more numerous cells from infected mice, concomitantly with a dramatic increase, detected by autoradiography, in the percentage of DNA-replicating cells of the monocyte-macrophage lineage. Peritoneal cells from healthy and from infected mice were fractionated on discontinuous Percoll gradients. Eight cell subsets were harvested in both cases, quantitated, and studied by electron microscopy. Two fractions (2 and 3: 1.041 < densities < 1.060 g/ml) from infected mice were greatly enriched in monoblasts and promonocytes. The cells of the different subsets were seeded separately, trypsin-treated and cultivated in vitro. Cultures of cell fractions 2 and 3 from infected mice contained the majority of the DNA-synthesizing cells and gave regularly rise to fibroblasts. Cultures of the different fractions were used for sequential morphological observations (2-11 days) at the electron microscope level. Early cultures were also used for the ultrastructural detection of the Mac-1 (CD 18/CD11b) surface antigen by gold immunocytochemistry. A few fibroblasts were rarely observed in cultures of fractions 2 and 3 from control mice, while cells with ultrastructural features of myofibroblasts were regularly observed in cultures of the same fractions harvested from mice with chronic schistosomiasis. Fractions 2and 3 from infected mice contained a large number of Mac-1 positive monoblasts. The correlations between the presence of monoblasts, DNA replication in cells ofthe monocyte-macrophage lineage and the appearance of myofibroblasts in culturesof the same fractions derived from infected mice are discussed.

Article Reference Frontal sinuses and human evolution
The frontal sinuses are cavities inside the frontal bone located at the junction between the face and the cranial vault and close to the brain. Despite a long history of study, understanding of their origin and variation through evolution is limited. This work compares most hominin species’ holotypes and other key individuals with extant hominids. It provides a unique and valuable perspective of the variation in sinuses position, shape, and dimensions based on a simple and reproducible methodology. We also observed a covariation between the size and shape of the sinuses and the underlying frontal lobes in hominin species from at least the appearance of Homo erectus. Our results additionally undermine hypotheses stating that hominin frontal sinuses were directly affected by biomechanical constraints resulting from either chewing or adaptation to climate. Last, we demonstrate their substantial potential for discussions of the evolutionary relationships between hominin species. Variation in frontal sinus shape and dimensions has high potential for phylogenetic discussion when studying human evolution.

Article Reference A multidisciplinary analysis of cesspits from late medieval and post-medieval Brussels, Belgium: diet and health in the fourteenth-seventeenth century
The fill of two late and post-medieval cesspits in Brussels was analyzed using a multidisciplinary approach, including the study of macrobotanical and faunal remains, pollen, and parasite eggs. These show that in the diet plant foods were dominated by cereals while the animal remains document the consumption of mainly fish and birds. The presence of foods that were luxuries at that time would indicate that these were affluent households, although with an admixture of meals related to those of lower socioeconomic status. Seven species of helminth and protozoal parasites were identified, with dominance of those species spread by poor sanitation.

Article Reference Les monuments funéraires gallo-romains et l’emploi de la pierre dans la région occidentale de la Civitas Treverorum
1. Les monuments funéraires trévires 1.1. Introduction Les monuments funéraires des Trévires sont le sujet de deux projets de recherche, menés par l’Académie des Sciences Autrichienne en coopération avec l’Université de Luxembourg d’une part et l’Université de Francfort et le Rheinisches Landesmuseum Trier d’autre part (Mahler, 2017). L’objectif de cette contribution est de présenter quelques réflexions préliminaires sur les analyses pétrographiques effectuées dans le cadre du projet austro-luxembourgeois. La cité des Trévires, située en Gaule Belgique, est appréciée depuis longtemps pour la quantité et la richesse de ses monuments funéraires de l’époque gallo-romaine, dont ceux provenant de Neumagen (von Massow, 1932) et d’Arlon (Espérandieu, 1913 ; Colling et al., 2009), pour ne citer que les ensembles les plus célèbres. Toutefois, cet ensemble n'a jamais fait l'objet d'un traitement scientifique et d'une évaluation exhaustive, étant donné que la zone d'étude est située à la frontière linguistique franco-allemande et comprend quatre États modernes (Kremer, 2018a ; Kremer, 2018b). De plus, les nouvelles découvertes des dernières décennies, comme celle du mausolée de Bertrange (Krier, 2003 ; Kremer, 2009) ou des monuments du Titelberg (Kremer, 2019), apportent des éclairages nouveaux sur l'évolution de la situation dans cette région et invitent à une enquête approfondie de l’ensemble des monuments connus. Dans le cadre du projet austro-luxembourgeois sur la partie occidentale de la civitas Treverorum, des analyses pétrographiques ont été initiées d’abord afin d'assurer une caractérisation et une détermination de provenance correctes des matériaux pierreux utilisés, ensuite afin d'obtenir des données nouvelles sur des questions d'organisation d'ateliers, de chronologie ou de relations économiques. Nous espérons contribuer à une meilleure compréhension de l'utilisation de la pierre dans le Nord de la Gaule, où la région trévire constituait une tache blanche sur la carte (Boulanger & Moulis, 2018). Une sélection représentative a été faite parmi les monuments accessibles de la zone de recherche ; toutefois, en l’absence d’exhaustivité, les résultats concernant la fréquence d'apparition des matériaux n’ont pas de valeur statistique. Ont été analysés les blocs de monuments funéraires exposés dans les musées de Luxembourg (MNHA), Arlon, Virton, Buzenol et Trèves. Des prélèvements ont été réalisés sur une série d’échantillons mise à disposition par le Centre national de recherche archéologique (CNRA) du Grand-Duché de Luxembourg. - Joint project FWF/FNR I 2269-G25: « Funerary Monuments from Western civitas Treverorum in an Interregional Context. The Inter-Connected Evaluation of a Socio-Historically Relevant Category of Finds ». Direction de projet : Gabrielle Kremer, ÖAI/ÖAW (lead) et Andrea Binsfeld, UniLu. Nous remercions les membres de l’équipe Sophie Insulander, Jean Krier, Sebastian Mühling et Christine Ruppert ainsi que les collègues du CNRA et du MNHA Luxembourg, du IAL et des Musées d’Arlon, Virton et Trèves. - Projet financé par la DFG : « Römische Grabdenkmäler aus Augusta Treverorum im überregionalen Vergleich: mediale Strategien sozialer Repräsentation ».
