Although the assembly of a ternary complex between the SNARE proteins syntaxin-1, SNAP25 and VAMP2 is known to be crucial for insulin exocytosis, the mechanisms controlling this key event are poorly understood. We found that pancreatic beta-cells express different isoforms of tomosyn-1, a syntaxin-1-binding protein possessing a SNARE-like motif. Using atomic force microscopy we show that the SNARE
Syndecan-2 is a heparan sulfate proteoglycan that has a cell adhesion regulatory domain contained within its extracellular core protein. Cell adhesion to the syndecan-2 extracellular domain (S2ED) is β1 integrin dependent; however, syndecan-2 is not an integrin ligand. Here the protein tyrosine phosphatase receptor CD148 is shown to be a key intermediary in cell adhesion to S2ED, with downstream β
Although endometriosis is considered an inflammatory disease, no reliable diagnostic biomarkers exist for use in clinical practice. The aim was to investigate the inflammatory profile in endometriosis using an exploratory approach of inflammation-related proteins. Patients with laparoscopy-verified endometriosis (N = 172), women with microscopic colitis (N = 50), healthy controls (N = 31), and age
Background: In a previous smaller study, we found evidence of a diminished global coagulation capacity after maximal exercise in patients with severe haemophilia A (HA). Aim: To validate these results, we repeated the study in a larger cohort. We also examined if the exercise-induced increased levels of von Willebrand factor (VWF) might prolong the effect of factor concentrate administered just be
Glucagon receptor (Gcgr) signaling maintains hepatic glucose production during the fasting state; however, the importance of the Gcgr for lipid metabolism is unclear. We show here that fasted Gcgr-/- mice exhibit a significant increase in hepatic triglyceride secretion and fasting increases fatty acid oxidation (FAO) in wild-type (WT) but not in Gcgr-/- mice. Moreover fasting upregulated the expre
Background: The power and influence of the hidden curriculum - culturally situated norms and values - onlearning opportunities is a growing concern in medical education. However, while medical schools producediversity and equal treatment policies, efforts towards surfacing and addressing equal opportunities in theclinical learning environment trail behind.Summary of Work: To better understand how
Circadian clocks were, until recently, seen as a consequence of rhythmic transcription of clock components, directed by transcriptional/translational feedback loops (TTFLs). Oscillations of protein modification were then discovered in cyanobacteria [1, 2]. Canonical posttranslational signaling processes have known importance for clocks across taxa [3, 4, 5, 6, 7, 8, 9, 10, 11]. More recently, evid
The authors analyzed the relationship between treatment, local recurrence, and metastases in a population‐based series of 375 patients with soft tissue sarcoma of the extremities and the trunk wall. Treatment was inadequate (marginal excision alone) in 107 patients, local recurrence occurred in 112, and 128 patients developed metastases. Local recurrence was 3.5 times more common after inadequate
Background: Perioperative fluid overload has been reported to increase complications after a variety of operative procedures. This study was conducted to investigate the incidence of fluid retention after pancreatic resection and its association with postoperative complications. Methods: Data from 1174 patients undergoing pancreatoduodenectomy between 2010 and 2016 were collected from the Swedish
At the core of this artistic doctoral thesis are four performance projects designed to counter the consumer-driven nature of contemporary performance-making while also addressing the need to develop sustainable methods of performance. Guided by the question: how to construct sustainable methods of performance for transformative encounters? the inquiry transcends the different layers of performance
The question of who China’s leftover men will marry is becoming a pressing issue for Beijing. The government’s response will shape the country’s future for decades to come.
Horizontal gene transfer by conjugative plasmids plays a critical role in the evolution of antibiotic resistance. Interactions between bacteria and other organisms can affect the persistence and spread of conjugative plasmids. Here we show that protozoan predation increased the persistence and spread of the antibiotic resistance plasmid RP4 in populations of the opportunist bacterial pathogen Serr
Bacterial engagement of specific host tissue structures can be a means of targeting a pathogen to a particular niche, establishing persistent infections and inducing invasion. In this context, primary adhesion is often the first crucial colonization step allowing pathogens to withstand the mechanical clearing mechanisms of the host. As a consequence, bacteria have evolved adhesins with the capacit
Despite the potentially strong effect of wind on bird orientation, our understanding of how wind drift affects migrating birds is still very limited. Using data from satellite-based radio telemetry, we analysed the effect of changing winds on the variation of the track direction of individual birds. We studied adults and juveniles of two raptor species, osprey Pandion haliaetus and honey buzzard P
Identifying mechanisms behind assortative mating is central to the understanding of ecological divergence and speciation. Recent studies show that populations of the freshwater isopod Asellus aquaticus can rapidly become locally differentiated when submerged Chara vegetation expands in lakes. In the novel Chara habitat, isopods have become lighter pigmented and smaller than in ancestral reed stand
