Histamine and chromogranin A-derived peptides in rat stomach ECL cells

Popular Abstract in Swedish ECL-cellen är en hormonproducerande cell i magslemhinnan. Den utsöndrar histamin vilken i sin tur reglerar magsäckens saltsyrautsöndring. I avhandlingen utvecklades en metod som möjliggör mätningar av histaminutsöndringen från ECL-celler i vakna råttor. Metoden bygger på att ett semipermeabelt membran opereras in i magslemhinnan varpå histamin och andra substanser som fThe ECL cells constitute the predominant endocrine cell population of the stomach. They secrete histamine which is a major stimulator of acid secretion. Chormogranin A (CgA)-derived peptides, such as pancreastatin, are co-secreted with histamine. In this thesis it was demonstrated that pancreastatin may serve as a reliable marker for ECL cell secretory activity in the rat. The function of pancreas

Blodig Pedagogik. Genus och våld i nationalistisk barn- och ungdomslitteratur.

This text is analysis of the use of violence in children's literature, specifically in the works of Penelope Delta (1874-1941), a Greek author. The analysis is concentrating of how violence is gendered and how nation and the experience of nation is gendered. It challanges the notion that nation and nationalism is a masculine discourse since Delta's use of violence is directed to both boys and girl

Turbulent flow in a ribbed channel analysed by the proper orhtogonal decomposition

Particle image velocimetry (PIV) measurements and proper orthogonal decomposition (POD) are used to explore the turbulent structures in a ribbed channel. In this study, only one channel wall is equipped with square ribs which are oriented transversely to the main stream direction. The ribs obstruct the channel by 20% of its height and are arranged 10 rib heights apart. The results include mean str
