A study was carried out in Niamey (capital city of Niger) to explore the market gardening periurban system. This activity is an option to minimize the risk of urban food insecurity in the Republic of Niger. In Niamey, you have two traditional areas to practise the market gardening production: Gamkalle and Yantala. The investigations study the area of Gamkalle. This study revealed more than 600 market gardening producers in Gamkalle. 50 producers of Gamkalle have been interviewed. These producers predominantly belong to the ethnic group “Zarma” and market gardening is their main economic activity. The principal period of production is during the dry season, the producers cultivate lettuce, cabbage, tomato, sweet pepper, beetroot, celery, carrot, parsley. Despite the higher costs notably in particular for input, the incomes generated by this activity are very high ($ 2805.23/year/acre). In conclusion, market gardening presents an opportunity for urban dwellers to increase and diversify their incomes and obtain food security. Nevertheless, there are many constraints to develop this production: land tenure security, pollution by industrial production and access to quality seeds, pesticides and fertilizers. [less ▲]

Pericardite aspergillaire avec tamponnade cardiaque et syndrome hemophagocytaire: un cas non classique d'immunodeficience

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 ▲]

Pericyte requirement for anti-leak action of angiopoietin-1 and vascular remodeling in sustained inflammation

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 ▲]

Perinatal growth hormone (GH) physiology : effect of GH-releasing factor on maternal and fetal secretion of pituitary and placental GH.

To study regulation of the secretion of human pituitary GH (hGH) and placental GH (hPGH) in the pregnant woman and human fetus, the GH-releasing factor Sermorelin [GRF-(l–29)-NH2] was administered to pregnant women at term (n = 5), just before elective cesarean section; saline was administered in control studies (n = 5). The effects of GRF-(1–29)-NH2 administration on maternal and fetal serum concentrations of hGH and GRF-(l–29)-NH2 and maternal serum levels of hPGH were evaluated at birth. The mean time span between injection and birth was 20 min (range, 15–25 min). Cord serum hGH concentrations were similar in infants of GRF-(1–29)-NH2-injected mothers and control infants. GRF-(l–29)-NH2 elicited a consistent but small rise in maternal hGH serum concentrations (P = 0.08), whereas hPGH concentrations remained unaltered. Finally, GRF-(l–29)-NH2 concentrations were undetectable in cord serum, but readily detectable in concomitantly obtained maternal serum. In conclusion, these data suggest that hGH secretion in the pregnant woman at term is suppressed at the pituitary level, that GRF does not affect hPGH secretion, and that fetal hGH secretion is independent of circulating maternal GRF, probably because of lack of transplacental GRF passage.
