Another alien bug in Europe: the first case of transcontinental introduction <br />of the Asiatic burrower bug Macroscytus subaeneus (Dallas, 1…
2019
The Oriental burrower bug Macroscytus subaeneus (Dallas, 1851) (Hemiptera: Heteroptera: Cydnidae: Cydninae), presently known only from single localities in Flores (Indonesia), the Philippines and Thailand, is recorded from the United Kingdom (hereafter U.K.). A single female specimen was collected on the semi-rural edge of Bath city by a Starling (Sturnus vulgaris L.) and taken to its nest from which it was retrieved during 2015. The specimen is illustrated and its diagnostic characters are provided. We hypothesize that this specimen could have been imported with a shipping container from Thailand.
Nesting of the Spotless Starling, <em>Sturnus unicolor</em>, on the island of Favignana (Aegadian Islands, Sicily)
2021
The presence of the Spotless Starling in Sicily was reported for the first time at the beginning of the XIX century, although the first nests for the province of Trapani are reported almost at the end of the XX century. As a breeder, the Spotless Starling remained absent from all the circumsicilian islands until the first report for the island of Pantelleria, in 2012. In 2020, the nest of Spotless Starling was observed on the island of Favignana, within a hole on an antenna. The couple fed the chicks with Ligia italica crustacean isopod of the family Ligiidae. The nesting on the island of Favignana confirms the continuous expansion of the species in Sicily.
Intestinal filtration as a consequence of increased mucosal hydraulic permeability
1980
Two mechanisms have been proposed to explain the secretory action of laxative compounds in the intestine: 1. increase of the intracellular amount of cyclic adenosine monophosphate due to stimulation of the adenylate cyclase system and 2. inhibition of intestinal transfer processes, in particular the Na,K-ATPase activated sodium absorption. In a set of in vivo and in vitro experiments in rat colon it could be demonstrated that dihydroxy bile acids (deoxycholate) and diphenolic laxatives (oxyphenisatin) enhance the hydraulic permeability of the mucosal tissue. The permeability changes take place--and there is good experimental evidence--at the zonulae occludentes which bind the epithelial cel…
Simon Starling, A l’ombre du pin tordu
2018
L’exposition consacrée à l’artiste britannique Simon Starling (1967/) à Sérignan témoigne exemplairement du tournant pris depuis les œuvres des années 1990 et 2000 dont l’une, Shedboatshed, lui a valu le prix Turner en 2005. À vrai dire, l’inflexion de son art vers une interrogation portant non sur l’identité, mais sur la présence était sensible dans une précédente exposition dédoublée entre le Mac/Val et le Parc Saint Léger en 2009. Pratiques de la déconstruction et de la reconstruction, le...
