Recent studies have highlighted a central role for intestinal dendritic cells (DCs) and vitamin A metabolite retinoic acid (RA) in the generation of alpha 4 beta 7(+) CCR9(+) "gut tropic" effector T cells. Here, using RA-responsive element reporter mice, we demonstrate that both splenic and mesenteric lymph node (MLN) DCs enhanced retinoic acid receptor (RAR) signaling in CD8(+) T cells; however,
The propagation of laminar and turbulent expanding flames subjected to Darrieus-Landau (DL), hydrodynamic instability was experimentally studied by employing stoichiometric H2/O2/N2 flames under quiescent and turbulent conditions performed in a newly developed medium-scale, fan-stirred combustion chamber. In quiescent environment, DL unstable laminar flame exhibits three-stage propagation, i.e. sm
Five protected analogues of beta-D-galctosyl-(5R)-5-hydroxy-L-lysine were prepared, in which the galactosyl moiety was modified by monodeoxygenation or inversion of stereochemistry at C-4. The building blocks were used in the solid-phase synthesis of a set of glycopeptides related to the peptide fragment CII256-273 from type II collagen. Evaluation of the glycopeptides revealed that T-cell hybrido
An assay has been established for quantitative evaluation of lentivirus coreceptor use with the help of GHOST(3) cells. GHOST(3) cells were derived from the human osteosarcoma cell line, HOS, and have been engineered to stably express CD4 and one or another of the chemokine receptors CCR3, CCR5, CXCR4, CXCR6/STRL33/Bonzo, or the orphan receptor GPR15/BOB. The indicator cell line carries the HIV-2
Women are at increased risk of complications after Cesarean section (CS) postpartum and in subsequent pregnancy and delivery. The overall aim of the thesis was to evaluate complications after CS, outline options for their management and to assess strategies to increase the rate of vaginal deliveries after CS (VBAC).Paper I was a prospective study where women were offered to have an additional appo
BakgrundFör att tackla den rådande SARS-COV-2-pandemin har det ställts höga krav på en snabb utveckling och utvärdering av nya antivirala läkemedel. Bland några av de antivirala läkemedelskandidaterna finns imiquimod, en TLR7 agonist normalt administrerad för behandling av könsvårtor och basalcellscarcinom. Eftersom det har påvisats att imiquimod kan öka den antivirala responsen, är vår hypotes at
Negotiated agreements are policy instruments that are increasingly used to manage environmental issues across a range of contexts. At their simplest, negotiated agreements are contractual arrangements between public authorities and an industry that the authorities have targeted to improve their environmental aspects. Part of the attraction of these agreements are the flexibility in their design, a
Det övergripande syftet med vår studie är att undersöka om företag har förändrat sitt hållbarhetsarbete på grund av den lågkonjunktur som inleddes år 2008. De företag vi har valt att studera har sedan några år tillbaka upprättat hållbarhetsredovisning enligt GRIs ramverk och har stort fokus på hållbarhet inom sin verksamhet. Vår studie är gjord utefter en kvalitativ forskningsmetod och är en multi
Visual information can be integrated in prominence perception, but most available evidence stems from controlled experimental settings, often involving synthetic stimuli. The present study provides evidence from spontaneously produced head gestures that occurred in Swedish television news readings. Sixteen short clips (containing 218 words in total) were rated for word prominence by 85 adult volun
During eyeblink conditioning, Purkinje cells that control blinking develop an inhibitory response to the conditional stimulus. This conditional response (CR) in the Purkinje cell shows a number of striking similarities to the overt blink CR, including adaptive timing. The evidence suggests that the Purkinje cell CR drives the overt CR. Recent results show that the Purkinje cell CR does not depend
Increased scholarly interest in ideas, goods and people that crossed the boundaries between modern empires (c. 1850-1914), known as transimperial history, has directed attention to microhistorical cases of individuals with transimperial careers. Such life trajectories are interesting in themselves, but their representativeness and broader significance for modern imperial history is often uncl
Purpose: The aim of this study is to explore teachers’ experience and understanding of classroom communication after participating in a speech-language pathologist (SLP) led in-service training on classroom communication. Method: This qualitative study used a focus group approach to explore how teachers describe their classroom communication. Twenty primary-school teachers participated. Thematic a
Topology optimization is used to design phononic bandgap materials that are tunable by mechanical deformation. A periodic media is considered, which due to the assumption of length scale separation, allows the dispersion relations to be obtained by analyzing a single unit cell subjected to Floquet–Bloch boundary conditions. A finite macroscopic deformation is applied to the unit cell to affect its
Proteomics Data Collection (ProDaC) is an EU-funded Coordination Action within the 6th framework programme. It aims to simplify the publication, dissemination and utilization of proteomics data by establishing standards that will support broad data collection from the research community. As a part of ProDaC, regular workshops are organized on a half-yearly basis to enable communication and discuss
BACKGROUND: Environmental contamination of norovirus (NoV) is believed to be a significant source for further transmission in hospitals.AIM: To investigate the risk of acquiring NoV in a cleaned room previously occupied by a patient with NoV infection. The risk of having a roommate with recent NoV infection was also assessed.METHODS: In a retrospective cohort, comprising 33,788 room stays at five
The response of soft colloids to crowding depends sensitively on the particles' compressibility. Nanogel suspensions provide model systems that are often studied to better understand the properties of soft materials and complex fluids from the formation of colloidal crystals to the flow of viruses, blood, or platelet cells in the body. Large spherical nanogels, when embedded in a matrix of smaller
Anastomotic defect (AD) after esophagectomy can lead to severe complications with need for surgical or endoscopic intervention. Early detection enables early treatment and can limit the consequences of the AD. As of today, there are limited methods to predict AD. In this study, we have used microdialysis (MD) to measure local metabolism at the intrathoracic anastomosis. Feasibility and possible di
