This study examines young people's involvement in regional sustainability transformation processes based on a real-world experiment in a community of 5700 inhabitants on the southern outskirts of city of Vienna, Austria. The eight-month experiment aimed to explore methods and tools for transdisciplinary co-creation with youth, the impact of structural conditions on their participation and the effects of their integration. Findings highlight the crucial roles of topics relevant to youth, a trusted intermediary like a youth worker, and structural conditions such as political support and resource allocation in enhancing youth engagement success.

Recently, prehospital identification of anterior large vessel occlusion (LVO) stroke has come into focus. Cortical signs have a high predictive value for the presence of LVO stroke but are often missed.

We previously reported the molecular design and the in vitro potency of recombinant monoclonal antibodies fused to a virus-derived peptide MHC class I complex that bypass the peptide processing and MHC loading pathway and directly displays a viral peptide in an MHC class I complex on the tumor cell surface. Here, we show that a vaccination-induced single peptide-specific CD8 T cell response was sufficient to eliminate B16 melanoma tumor cells in vivo in a fully immunocompetent, syngeneic mouse tumor model when mice were treated with mouse pMHCI-IgGs fusion proteins targeting the mouse fibroblast activation protein.

This important step is usually performed by one specific SUC in every species. However, plants possess small families of several different SUCs which are less well understood.

Calmodulin (CaM) is a calcium-sensing protein that was shown to bind to some RLKs such as the PHYTOSULFOKINE RECEPTOR1 (PSKR1). The CaM-binding site is embedded in subdomain VIa of the kinase domain.

Cyclic nucleotide-gated channels (CNGCs) are Ca2+-permeable channels that interact with the ubiquitous Ca2+ sensor calmodulin (CaM). CNGCs interact with CaMs via diverse CaM-binding sites, including an IQ-motif, which has been identified in the C-termini of CNGC20 and CNGC12.

Different from such a polyclonal T-cell recruitment, an alternative concept is to engage only antigen-specific T-cell subsets. Recruitment of specific subsets of T cells may be as potent but potentially lead to fewer side effects.

Disturbances in the endothelial integrity can lead to insufficient blood supply and bear the risk of thrombus formation and acute vascular occlusion. At present, effective therapeutics to restore endothelial integrity are barely available.

To elucidate PSK receptor function we analyzed PSKR1 kinase activity and binding to Ca(2+) sensors and evaluated the contribution of these activities to growth control in planta. Ectopically expressed PSKR1 was capable of auto- and transphosphorylation.

Although CaM binding has been shown to be important for Ca(2+)-dependent feedback regulation of CNGC activity, the CaM-binding properties of these channels have been investigated in a few cases only. We show that CNGC20 from Arabidopsis thaliana binds CaM in a Ca(2+)-dependent manner and interacts with all AtCaM isoforms but not with the CaM-like proteins CML8 and CML9.

We found that ATG activated tissue factor procoagulant activity (TF PCA) on monocytic cells more potently than other stimuli that decrypt TF, including cell disruption, TF pathway inhibitor inhibition, and calcium ionophore treatment. Induction of TF PCA by ATG was dependent on lipid raft integrity and complement activation.

Current research is focused on the role of adipokines such as adiponectin and immune cells, especially macrophages, in adipose tissue. Our aim was to examine the role of inflammation not in tissue but in the peripheral blood of healthy overweight and obese subjects.

Brain and immune system are linked by bidirectional pathways so that changes of the central nervous system may influence various immune functions. The olfactory system may be involved in this interaction. In most odor studies subjects are aware of an odor exposure, using frequently high odor concentrations or long-term exposures without controls.
View Article and Find Full Text PDFSeveral lines of evidence point to a close relationship between the hormones of energy homeostasis and the olfactory system. Examples are the localization of leptin and adiponectin receptors in the olfactory system or increased activation of brain regions related to the palatability and the hedonic value of food in response to food pictures after application of ghrelin. In this preliminary study, we tested in 31 subjects (17 male and 14 female) if and to what extent the peripheral blood concentrations of "satiety" hormones, such as leptin, adiponectin, and ghrelin (acyl and total), are correlated with the self-ratings of odor pleasantness and with the objective olfactory and gustatory ability.
