We report the case of a 31-year-old woman who died in a context of haemophagocytic syndrome with multiple opportunist infections:viral, mycobacterial and fungal. To our knowledge, this is the tenth case of invasive aspergillosis manifested by an aspergillus pericarditis with cardiac tamponade. Search for HIV infection, neoplasia, haematological malignancies was negative. In addition, the patient carried on a nonviral, non-ethylic cirrhosis, the etiology of which remained unknow. We will particularly develop the aspergillus pericarditis with cardiac tamponade and the haemophagocytic syndrome. [less ▲]

Pericopsis elata (Fabaceae – assamela, afrormosia, kokrodua) is a high valued timber species of the moist semi deciduous African forests. Because of logging which started more than 50 years ago, it is considered as threatened and included on both IUCN Red List and CITES Appendix II. Nevertheless, there is still little information available on the species ecology: essential biological parameters controlling its population dynamics remain unknown. Our study first aims at improving the knowledge of its main ecological parameters, then at assessing the impact of selective logging on its populations in a forest management unit in Cameroon (ca 120,000 ha). After inventorying the species (sampling rate of 1.2%), mortality and growth were assessed over continuous 5 and 2-year periods in unlogged and logged areas, respectively. Phenology was monitored in the unlogged forest during 5 years (leaf shedding and flushing, flowering, ripe and unripe fruiting). The population structure followed a bell-shaped curve. Mean annual diameter increments in both environments did not differ significantly between unlogged and logged areas (0.29±0.06 0.31±0.04 cm for unlogged and logged areas, respectively). P. elata is a deciduous species that flowers at the end of the main dry season (Marsh-April). The minimum reproduction and effective flowering diameters were, respectively, 32 and 37 cm. Fruit maturation took place during 7 months (the seed rain occurs in December-January), but all unripe fruits abort 3 years out of 5. With a minimum logging diameter of 90 cm, the recovery rate computed over a 30-year period was greater than 100%. Selective logging harvested only 12.1% of the total number of seed trees and had little influence on the species biological parameters. Securing sufficient regeneration as a post-logging action is probably the most important consideration for achieving long-term sustainability. [less ▲]

Pericopsis elata (gregarious Fabaceae), a moist semi-deciduous hardwood logged in Central African forests, is on the IUCN Red List and in CITES Appendix II. Our study evaluated its main ecological and pedological parameters in Cameroon. We obtained a mean diameter increment of 0.32 ± 0.04 cm.year–1. Minimum fertile and effective fruiting diameters were 32 and 35 cm, respectively. Flowering started in March-April, and fruits ripened over 7 months. Seed rain was studied in 1 × 45 m cleared corridors in each cardinal direction around 4 isolated mother trees. Indehiscent pods (average weight: 131.6 ± 10.1 cg) were dispersed mainly to the west: 86% of the variation of the number of collected fruits could be explained by the distance to the mother tree and the direction (GLM analysis, p < 0.001). The proportion of seeds eaten by insect larvae depended on the mother tree (10–95% – χ2 test, p < 0.001). Soils were compared at a regional scale: soils with P. elata contain higher levels of C (2.2 ± 0.5 SD- g.100g–1), Fe (261 ± 83 mg.kg–1), and P (33 ± 10 mg.kg–1), and were more acidic (pH 4.0 ± 0.2). A planting method in logging gaps is currently being tested taking into account physicochemical soil parameters [less ▲]

Blood vessel leakiness is an early, transient event in acute inflammation but can also persist as vessels undergo remodeling in sustained inflammation. Angiopoietin/Tie2 signaling can reduce the leakiness through changes in endothelial cells. The role of pericytes in this action has been unknown. We used the selective PDGF-B-blocking oligonucleotide aptamer AX102 to determine whether disruption of pericyte-endothelial crosstalk alters vascular leakiness or remodeling in the airways of mice under four different conditions: i) baseline, ii) acute inflammation induced by bradykinin, iii) sustained inflammation after 7-day infection by the respiratory pathogen Mycoplasma pulmonis, or iv) leakage after bradykinin challenge in the presence of vascular stabilization by the angiopoietin-1 (Ang1) mimic COMP-Ang1 for 7 days. AX102 reduced pericyte coverage but did not alter the leakage of microspheres from tracheal blood vessels at baseline or after bradykinin; however, AX102 exaggerated leakage at 7 days after M. pulmonis infection and increased vascular remodeling and disease severity at 14 days. AX102 also abolished the antileakage effect of COMP-Ang1 at 7 days. Together, these findings show that pericyte contributions to endothelial stability have greater dependence on PDGF-B during the development of sustained inflammation, when pericyte dynamics accompany vascular remodeling, than under baseline conditions or in acute inflammation. The findings also show that the antileakage action of Ang1 requires PDGF-dependent actions of pericytes in maintaining endothelial stability. [less ▲]

L’influence de la Chine en république démocratique du Congo (RDC) se caractérise par son caractère tardif mais fulgurant, au regard d’une présence chinoise historiquement forte en Afrique subsaharienne. Son implantation offensive en RDC résulte d’une convergence d’intérêts entre un État chinois en quête de matières premières et de terres arables pour assurer son développement économique et sa stabilité politique, et un État congolais en (re)construction résolument acquis, depuis l’élection du président Joseph Kabila, au modèle de développement chinois fondé sur la séparation volontaire entre objectifs économiques et réformes politiques (prêts inconditionnés, aide déliée). En consacrant l’accroissement rapide des relations commerciales sino-congolaises, le partenariat stratégique Chine-Afrique, scellé en 2006 lors du troisième Forum de coopération sino-africain, participe plus largement de la remise en cause du rôle des puissances traditionnellement influentes dans la région. Au-delà de la concurrence économique induite vis-à-vis des États-Unis, du Japon et des institutions financières internationales au sein desquelles elle est largement représentée, l’Europe assiste plus singulièrement à la remise en question de son leadership régional et à la dépréciation normative de sa politique développementale. Entre émancipation et hégémonie, cet article vise à mettre au jour les enjeux stratégiques inhérents à l’impact du "facteur chinois" en RDC. [less ▲]

The objective of this prospective study was to investigate the success rate, practicality and complications of a new perilimbal pocket technique for the replacement of prolapsed nictitans gland in 30 dogs (44 eyes). A first incision was made in the bulbar conjunctiva, 2-3 mm from and parallel to the infero-nasal limbus, a second incision on the bulbar aspect of the nictitating membrane (NM), 2-3 mm parallel to the free edge. The gland was returned to its normal position by suturing the subconjunctival tissues of the NM to the episcleral tissues, using four to six interrupted horizontal mattress sutures. The English bulldog, Neapolitan mastiff, great dane and American cocker spaniel were commonly presented. Nictitans gland prolapse occurred prior to one year of age in 83.3 per cent of dogs, and unilaterally in 15 patients. The procedure was easy to perform, and had a 90.9 per cent success rate, with minimal complications. The median duration of follow-up, conducted by ophthalmic examination or telephone contact with the owners, was 21.5 months. Tear production and ocular health were not affected in 17 eyes with at least six months follow-up. There was a statistically significant increase between preoperative and postoperative Schirmer tear test-1 measurements. [less ▲]

La vallée du Kou a été depuis le milieu des années 70, le lieu d’un développement rapide de l’irrigation. Reconnue comme une excellente plaine à vocation agricole notamment pour la riziculture, en raison de ses importantes potentialités hydrauliques le périmètre irrigué de la vallée du Kou revêt une importance majeure dans les économies des communautés rurales et urbaines situées à proximité. D’une superficie totale aménagée de 1.260 ha, l’aménagement dudit périmètre à vocation rizicole a été réalisé de 1969 à 1970 dans le cadre de l’autosuffisance alimentaire. Malheureusement, ce périmètre est aujourd’hui peu performant à cause de la réduction progressive des surfaces emblavées au fil des années et de la faible productivité. De 7 t/ha environ de paddy par campagne pendant les premières années après l’aménagement, les rendements sont passés à 4 t/ha dans les dernières années. Actuellement, en station d’essai, les rendements atteignent 7 à 8 t/ha. Cela montre donc clairement les possibilités d’accroître les rendements sur les périmètres irrigués. Les causes principales de cette contre performance sont des pénuries en eau chroniques due à une intensification des utilisateurs en amont du périmètre et la mauvaise gestion de l’eau sur le périmètre. La question de la gestion de l’eau d’irrigation devient alors primordiale. C’est dans ce sens qu’il a été jugé nécessaire d'entreprendre une stratégie d'amélioration de la gestion de l'irrigation sur le périmètre. Après avoir élaboré un diagnostic des efficiences en irrigation, le logiciel SIMIS a été mis en place afin de proposer des scénarii d’irrigation fiables et équitables. [less ▲]
