Ecological plant epigenetics: Evidence from model and non-model species, and the way forward
2017
Growing evidence shows that epigenetic mechanisms contribute to complex traits, with implications across many fields of biology. In plant ecology, recent studies have attempted to merge ecological experiments with epigenetic analyses to elucidate the contribution of epigenetics to plant phenotypes, stress responses, adaptation to habitat, and range distributions. While there has been some progress in revealing the role of epigenetics in ecological processes, studies with non-model species have so far been limited to describing broad patterns based on anonymous markers of DNA methylation. In contrast, studies with model species have benefited from powerful genomic resources, which contribute…
Evolutionary conservation advice for despotic populations: habitat heterogeneity favours conflict and reduces productivity in Seychelles magpie robins
2010
Individual preferences for good habitat are often thought to have a beneficial stabilizing effect for populations. However, if individuals preferentially compete for better-quality territories, these may become hotspots of conflict. We show that, in an endangered species, this process decreases the productivity of favoured territories to the extent that differences in productivity between territories disappear. Unlike predictions from current demographic theory on site-dependent population regulation (ideal despotic distribution), we show that population productivity is reduced if resources are distributed unevenly in space. Competition for high-quality habitat can thus have detrimental con…

Laparoscopic treatment for esophageal achalasia: experience at a single center
2013
Background. Achalasia is a not frequent esophageal disorder cha- racterized by the absence of esophageal peristalsis and incomplete re- laxation of the lower esophageal sphincter (LES). Its cause is unknown. The aim of treatment is to improve the symptoms. We report the results of the treatment of this condition achieved in one center. Patients and methods. We conducted a retrospective study of pa- tients with esophageal achalasia. In the period 2010-2012 we observed 64 patients, of whom 19 were referred for medical treatment. Three of Introduction Achalasia is a not frequent esophageal motor disor- der that affects both the body of the esophagus and the lower esophageal sphincter (LES). It…
The Value of Scoring Achalasia: A Comparison of Current Systems and the Impact on Treatment–The Surgeon's Viewpoint
2007
Heller myotomy in patients with achalasia promises better long-term success than pneumatic dilation, especially in younger patients, and therefore has evolved as the primary treatment option. The aim of this study was to evaluate the impact of different disease-specific severity scores on achalasia treatment. Fifty consecutive patients undergoing pneumatic dilation (n = 25) or myotomy (n = 25) were assessed pre- and postinterventionally by clinical evaluation using the Eckardt Score, the Vantrappen Classification, and the Adams's Stages, as well as by radiologic and manometric studies and by subjective evaluation. The Eckardt Score and the Vantrappen Classification correlated significantly…
L’immagine di Agatocle e l’arte dell’età di Agatocle
2013
La tradizione letteraria, spesso ostile, ci restituisce in termini assai nitidi un’immagine di Agatocle del tutto in linea con le tendenze eminenti nell’arte aulica del Primo Ellenismo. Il Siracusano risulta aver sfruttato con abilità e perspicacia i clichés dell’ideologia regale affermatasi tra i Diadochi e gli Epigoni, nei regni originatisi dalla divisione dell’impero di Alessandro, fondata sull’esaltazione delle virtù militari eccezionali e del carisma del re (degno emulo del grande Macedone), e del suo stile di vita “straordinario”, cui le grandi feste e i banchetti danno occasione di ostentare magnificenza e generosità, definendo altresì le nuove gerarchie sociali. Da un lato quindi il…
