Empirical and theoretical evidence suggests that facilitation between plants, when it occurs, is more likely during periods of abiotic stress, while competition predominates under more moderate conditions. Therefore, one might expect the relative importance of competition vs. facilitation to vary seasonally in ecosystems characterized by pronounced dry (abiotically stressful) and wet (benign) s...

Tropical forage genetic resources are essential material for the development of adapted pasture crops. Collection, conservation and characterization of these resources are needed to preserve them for future generations. Collections were made after 1970 by CIAT, CSIRO and ILRI. The current status of these collections and present conservation methods are reviewed. Genetic diversity has been asses...

BACKGROUND Pancreas divisum, the most common congenital anomaly of the pancreas, is caused by failure of the fusion of the ventral and dorsal pancreatic duct systems during embryological development. Although various pancreatic tumors can occur in patients with pancreas divisum, intraductal papillary mucinous neoplasm is rare. CASE PRESENTATION A 77-year-old woman was referred to our hospital...

tion of the minor papilla in pancreas divisum A 70-year-old woman was admitted with an episode of epigastric pain radiating into her back, accompanied by intermittent nausea and vomiting. Acute pancreatitis was diagnosed and transabdominal ultrasound revealed a dilated pancreatic duct of 6mm due a ductal stone. The first attempt of endoscopic retrograde pancreatography (ERP) failed to cannulate...

Résumé P. E. H. Haïr — Milho, meixoeira et autres aliments de la garnison de Sofala, 1505-1525. Les archives du comptoir portugais de Sofala nous éclairent quelque peu sur la nature des plantes alimentaires utilisées au XVIe siècle sur la côte orientale. Les termes milho et meixoeira paraissent désigner respectivement le sorgho et le pennisetum, plutôt que le sorgho et le maïs, comme on l'avait...

Pancreas divisum (PD) is the most common congenital variant of the pancreas and has been implicated as a cause of pancreatitis; however, endoscopic treatment is controversial. Our objective was to examine patient response to endotherapy for treatment of symptomatic PD in adult patients in a systematic review of the literature. A systematic review of all case series and case-control studies with...
