Le théâtre en Thaïlande

La Thaïlande s'enorgueillit à juste titre d'une tradition théâtrale propre, et de haute réputation. L'imagerie touristique met en bonne place, parmi les fruits exotiques et les temples bouddhistes, ces charmantes danseuses aux costumes miroitants et aux gestes raffinés, qui exécutent des danses autrefois réservées aux seuls plaisirs royaux. Pourtant, arrivé au « Pays du sourire », et après quelques recherches infructueuses, c'est la rareté des spectacles qui frappe. Aucun théâtre permanent n'..

The KongoKing project: 2012 fieldwork report from the lower Congo province (DRC)

In order to understand the origins of the Kongo kingdom, the KongoKing research group conducted a first survey in the area usually regarded as the former kingdom’s provincial capital sites of Mbanza Nsundi and Mbanza Mbata in the Lower Congo Province of the DRC during the summer of 2012. Several test excavations and radiocarbon dates are starting to shed some light on the last five centuries in the area

L’histoire du royaume Kongo revisitée par l’archéologie

Dans ce chapitre nous présentons la synthèse des résultats des recherches archéologiques réalisées au cours du projet KongoKing subdivisée en deux époques : l’Âge du Fer Ancien d’une part et, d’autre part, l’Âge du Fer Récent qui inclut la période historique du royaume Kongo. Nous présentons alors un nouveau bilan du développement du royaume Kongo en croisant ces nouvelles données fournies par l’archéologie avec l’histoire et les traditions orales et nous finissons en mettant en relief nos découvertes concernant plusieurs thématiques

Effect of fixed orthodontic appliances on salivary microbial parameters at 6 months:a controlled observational study

Objective: The aim of this study was to assess the microbial changes in children with fixed orthodontic appliances compared with a control group of children without orthodontic treatment. Material and Methods: Ninety-five children, aged between 12 and 16 years, participated in this study. Forty-eight subjects were fitted with fixed orthodontic appliances and forty-seven were free of any such appliances. The follow-up was 6 months for all children. The association between orthodontic appliances and high levels of Streptococcus mutans and Lactobacillus spp was assessed with logistic regression models, taking age, sex, pH and buffer capacity into account. Results: Differences at baseline between the two groups were not statistically significant. We found that wearing a fixed orthodontic appliance was associated with high levels of Streptococcus mutans and Lactobacillus spp (adjusted OR: 6.65, 95% CI [1.98-22.37]; 9.49, 95% CI [2.57-35.07], respectively), independently of other variables. Conclusion: The originality of the present epidemiological study was to evaluate the evolution of salivary microbial parameters in a population of children with fixed orthodontic appliances. Our results show an increase of Streptococcus mutans and Lactobacillus spp values during the follow-up. The whole dental workforce should be aware that preventive measures are of paramount importance during orthodontic treatment

Advances in Carcinogenic Metal Toxicity and Potential Molecular Markers

Metal compounds such as arsenic, cadmium, chromium, cobalt, lead, mercury, and nickel are classified as carcinogens affecting human health through occupational and environmental exposure. However, the underlying mechanisms involved in tumor formation are not well clarified. Interference of metal homeostasis may result in oxidative stress which represents an imbalance between production of free radicals and the system’s ability to readily detoxify reactive intermediates. This event consequently causes DNA damage, lipid peroxidation, protein modification, and possibly symptomatic effects for various diseases including cancer. This review discusses predominant modes of action and numerous molecular markers. Attention is paid to metal-induced generation of free radicals, the phenomenon of oxidative stress, damage to DNA, lipid, and proteins, responsive signal transduction pathways with major roles in cell growth and development, and roles of antioxidant enzymatic and DNA repair systems. Interaction of non-enzymatic antioxidants (carotenoids, flavonoids, glutathione, selenium, vitamin C, vitamin E, and others) with cellular oxidative stress markers (catalase, glutathione peroxidase, and superoxide dismutase) as well as certain regulatory factors, including AP-1, NF-κB, Ref-1, and p53 is also reviewed. Dysregulation of protective pathways, including cellular antioxidant network against free radicals as well as DNA repair deficiency is related to oncogenic stimulation. These observations provide evidence that emerging oxidative stress-responsive regulatory factors and DNA repair proteins are putative predictive factors for tumor initiation and progression
