Repurchase intentions in a retail store - exploring the impact of colours
The purpose of the paper is to explore the elements that influence customer loyalty in different dominant
colour environments in a retail store that sells groceries. The paper explores the relationship between customer
satisfaction, exploring the store environment, communications with sales personnel and repurchase
intentions in different colour environments. Furthermore, it explores the gender impact on creating customer
loyalty in warm, cool and neutral colour environments. Empirical research is conducted using three
different colour environments in a retail store that sells groceries. Based on research findings, exploring
store environment is found to be the most influential element that boosts repurchase intentions. Gender
stimulated differences are also found. For women, in warm, cool and neutral colour environment the dominant
influence on repurchase intentions is exploring the store environment. For men, in both warm and
cool colour environment communication with sales personnel influences their repurchase intentions. The
research contributes to the existing body of knowledge on the influence of colours on repurchase intentions
in the context of South-East European culture. Managerial implications are offered and suggestions
for further research provided
IL-33 Receptor-Expressing Regulatory T Cells Are Highly Activated, Th2 Biased and Suppress CD4 T Cell Proliferation through IL-10 and TGFβ Release
Immunomodulatory Foxp3+ regulatory T cells (Tregs) form a heterogeneous
population consisting of subsets with different activation states, migratory
properties and suppressive functions. Recently, expression of the IL-33
receptor ST2 was shown on Tregs in inflammatory settings. Here we report that
ST2 expression identifies highly activated Tregs in mice even under
homeostatic conditions. ST2+ Tregs preferentially accumulate at non-lymphoid
sites, likely mediated by their high expression of several chemokine receptors
facilitating tissue homing. ST2+ Tregs exhibit a Th2-biased character,
expressing GATA-3 and producing the Th2 cytokines IL-5 and IL-13 –especially
in response to IL-33. Yet, IL-33 is dispensable for the generation and
maintenance of these cells in vivo. Furthermore, ST2+ Tregs are superior to
ST2− Tregs in suppressing CD4+ T cell proliferation in vitro independent of
IL-33. This higher suppressive capacity is partially mediated by enhanced
production and activation of the anti-inflammatory cytokines IL-10 and TGFβ.
Thus, ST2 expression identifies a highly activated, strongly suppressive Treg
subset preferentially located in non-lymphoid tissues. Here ST2+ Tregs may be
well positioned to immediately react to IL-33 alarm signals. Their specific
properties may render ST2+ Tregs useful targets for immunomodulatory
therapies
System size and centrality dependence of the balance function in A+A collisions at sqrt[sNN]=17.2 GeV
Electric charge correlations were studied for p+p, C+C, Si+Si, and centrality selected Pb+Pb collisions at sqrt[sNN]=17.2 GeV with the NA49 large acceptance detector at the CERN SPS. In particular, long-range pseudorapidity correlations of oppositely charged particles were measured using the balance function method. The width of the balance function decreases with increasing system size and centrality of the reactions. This decrease could be related to an increasing delay of hadronization in central Pb+Pb collisions

Detection of cannabinoid receptor type 2 in native cells and zebrafish with a highly potent, cell-permeable fluorescent probe.
Despite its essential role in the (patho)physiology of several diseases, CB2R tissue expression profiles and signaling mechanisms are not yet fully understood. We report the development of a highly potent, fluorescent CB2R agonist probe employing structure-based reverse design. It commences with a highly potent, preclinically validated ligand, which is conjugated to a silicon-rhodamine fluorophore, enabling cell permeability. The probe is the first to preserve interspecies affinity and selectivity for both mouse and human CB2R. Extensive cross-validation (FACS, TR-FRET and confocal microscopy) set the stage for CB2R detection in endogenously expressing living cells along with zebrafish larvae. Together, these findings will benefit clinical translatability of CB2R based drugs

Large-Scale Recombinant Production of the SARS-CoV-2 Proteome for High-Throughput and Structural Biology Applications
The highly infectious disease COVID-19 caused by the Betacoronavirus SARS-CoV-2 poses a severe threat to humanity and demands the redirection of scientific efforts and criteria to organized research projects. The international COVID19-NMR consortium seeks to provide such new approaches by gathering scientific expertise worldwide. In particular, making available viral proteins and RNAs will pave the way to understanding the SARS-CoV-2 molecular components in detail. The research in COVID19-NMR and the resources provided through the consortium are fully disclosed to accelerate access and exploitation. NMR investigations of the viral molecular components are designated to provide the essential basis for further work, including macromolecular interaction studies and high-throughput drug screening. Here, we present the extensive catalog of a holistic SARS-CoV-2 protein preparation approach based on the consortium’s collective efforts. We provide protocols for the large-scale production of more than 80% of all SARS-CoV-2 proteins or essential parts of them. Several of the proteins were produced in more than one laboratory, demonstrating the high interoperability between NMR groups worldwide. For the majority of proteins, we can produce isotope-labeled samples of HSQC-grade. Together with several NMR chemical shift assignments made publicly available on covid19-nmr.com, we here provide highly valuable resources for the production of SARS-CoV-2 proteins in isotope-labeled form
Clinical and molecular analysis of a novel variant in heme oxygenase-1 deficiency: Unraveling its role in inflammation, heme metabolism, and pulmonary phenotype
Heme oxygenase 1 (HO-1) is the pivotal catalyst for the primary and rate-determining step in heme catabolism, playing a crucial role in mitigating heme-induced oxidative damage. Pathogenic variants in the HMOX1 gene which encodes HO-1, are responsible for a severe, multisystem disease characterized by recurrent inflammatory episodes, organ failure, and an ultimately fatal course. Chronic hemolysis and abnormally low bilirubin levels are cardinal laboratory features of this disorder. In this study, we describe a patient with severe interstitial lung disease, frequent episodes of hyperinflammation non-responsive to immunosuppression, and fatal pulmonary hemorrhage. Employing exome sequencing, we identified two protein truncating variants in HMOX1, c.262_268delinsCC (p.Ala88Profs*51) and a previously unreported variant, c.55dupG (p.Glu19Glyfs*14). Functional analysis in patient-derived lymphoblastoid cells unveiled the complete absence of HO-1 protein expression and a marked reduction in cell viability upon exposure to hemin. These findings confirm the pathogenicity of the identified HMOX1 variants, further underscoring their association with severe pulmonary manifestations . This study describes the profound clinical consequences stemming from disruptions in redox metabolism
