This study examines innate immunity to oral Salmonella during primary infection and after secondary challenge of immune mice. Splenic NK and NKT cells plummeted early after primary infection, while neutrophils and macrophages (M{phi}) increased 10- and 3-fold, respectively. In contrast, immune animals had only a modest reduction in NK cells, no loss of NKT cells, and a slight increase in phagocyte
We found that engagement of beta (2) integrins on human neutrophils induced activation of RhoA, as indicated by the increased ratio of GTP:GTP + GDP recovered on RhoA and translocation of RhoA to a membrane fraction. The clustering of beta (2) integrins also induced a time-dependent increase in GDP bound to RhoA, which correlated with beta (2) integrin-induced activation of p190RhoGAP. The activat
Background and purpose — Modular-neck hip stems have been identified with corrosion-related problems from the neck–stem junction. We report an ongoing varus deformity of modular-neck hip stems with simultaneous metal ion release observed during a study comparing the migration of modular vs. standard hip stems. Patients and methods — We followed 50 patients with modular and 25 with standard neck st
The effects of p-chloromercuribenzoic acid and chloromercuribenzene-p-sulphonic acid on pancreatic islets were studied in vitro. Obese–hyperglycaemic mice were used as the source of microdissected islets containing more than 90% β-cells. p-Chloromercuribenzoic acid and chloromercuribenzene-p-sulphonic acid stimulated insulin release at concentrations of 0.01mm or above. This stimulation was signif
In normal cells, activation of cyclin-dependent kinases (cdks) requires binding to a cyclin and phosphorylation by the cdk-activating kinase (CAK). The Kaposi's sarcoma-associated herpesvirus encodes a protein with similarity to D-type cyclins. This KSHV-cyclin activates CDK6, alters its substrate specificity, and renders CDK6 insensitive to inhibition by the cdk inhibitor p16INK4a. Here we invest
BACKGROUND: Transient tachypnoea of the newborn (TTN) is characterized by tachypnoea and signs of respiratory distress. Transient tachypnoea typically appears within the first two hours of life in term and late preterm newborns. The administration of corticosteroids might compensate for the impaired hormonal changes which occur when infants are delivered late preterm, or at term but before the ons
Background: Acute kidney injury (AKI) is a serious complication of out-of-hospital cardiac arrest (OHCA). Post-resuscitation cardiogenic shock (CS) is a key contributing factor. Targeting a higher arterial carbon dioxide tension may affect AKI after OHCA in patients with or without CS. Methods: Pre-planned exploratory study of a multi-national randomised trial comparing targeted mild hypercapnia o
In this introduction, we explain how the chapters in this volume give support to the idea that different accounts of active cognition in the history of philosophy directly or indirectly respond to Aristotle’s account of cognition in his De anima.
In recent years, there has been a renewed interest in anarchism from both social movements and critical academic circles. When tracing the genealogy of anarchist perspectives since the nineteenth century, radical geographers have pointed out the importance of the anarchist movement in Spain, and particularly in the city of Barcelona. During the 1960s and 1970s, authors like Murray Bookchin shared
The main information in DNA is its four-letter sequence that builds up the genetic information and that is traditionally read using sequencing methodologies. DNA can, however, also carry other important information, such as epigenetic marks and DNA damage. This information has recently been visualized along single DNA molecules using fluorescent labels. Quantifying fluorescent labels along DNA is
Taking a psychological and philosophical outlook, we approach making as an embodied and embedded skill via the skilled artisan’s experience of having a corporeal, nonlinguistic dialogue with the material while working with it. We investigate the dynamic relation between maker and material through the lens of pottery as illustrated by wheel throwing, claiming that the experience of dialogue signals
This paper examines the possibility of identifying votive offerings among a collection of stray finds in a Late neolithic material from one farm land on the island Hven.First, I identify the Late neolithic artefacts in a collection of stray finds and make a register as well as take photographes of the artefacts. Then I compare these stray finds with material from hoards found in Scania to analyz i
Objective: To investigate the ability of statins to activate the nuclear receptor peroxisome proliferator-activated receptor gamma (PPAR-γ) in primary human monocytes in culture. Materials and methods: Human peripheral monocytes were incubated with atorvastatin (0.1-10 μmol/1) for up to 24 hours. PPAR-γ expression was analysed by electrophoretic mobility shift assay. Pro-inflammatory cytokines wer
Classical dendritic cells (cDC) can be classified into two major subsets: Irf8-dependent cDC1 and Irf4-expressing cDC2. Although these subsets play distinct roles in intestinal immune homeostasis, their functions in T cell-driven colitis remain unknown. To assess the role of IRF4 expression in cDC2 in T cell-driven colitis, CD11c-Cre.Irf4fl/fl and Irf4fl/fl mice were backcrossed onto a Rag-1-/- ba
