Design and marketing: Intersections and challenges
This editorial article reports on interdisciplinary research being conducted at the
interface between the scientific disciplines of marketing and design. It reviews the
11 academic papers from the special issue situated at this intersection, thereby
showing the richness of research happening in this liminal area. At the same time, the
paper observes how the disciplines' different scopes as well as their different modi
operandi inhibit the collaboration between marketing and design research. Whereas
marketing largely follows the paradigm of empirical realism asking how the current
world works, design largely follows the pragmatist paradigm asking how a future
world can be shaped. Finally, this paper contains a number of suggestions on how to
foster cooperation between the two disciplines.FCT:UIDB/04020/2020info:eu-repo/semantics/publishedVersio
The interplay of marketing and design
This paper provides insights into the interdisciplinary intersections between marketing and design. It explores the various design intersections in the marketing fields. The collaboration between marketing and design is restricted by the paradigm boundaries, but not by the industry, researchers, and research projects. Challenges for both disciplines' future are explored, highlighting the need for a paradigm shift in marketing.FCT: UIDB/04020/2020info:eu-repo/semantics/publishedVersio
Combining heterogeneous subgroups with graph-structured variable selection priors for Cox regression
Important objectives in cancer research are the prediction of a patient's
risk based on molecular measurements such as gene expression data and the
identification of new prognostic biomarkers (e.g. genes). In clinical practice,
this is often challenging because patient cohorts are typically small and can
be heterogeneous. In classical subgroup analysis, a separate prediction model
is fitted using only the data of one specific cohort. However, this can lead to
a loss of power when the sample size is small. Simple pooling of all cohorts,
on the other hand, can lead to biased results, especially when the cohorts are
heterogeneous. For this situation, we propose a new Bayesian approach suitable
for continuous molecular measurements and survival outcome that identifies the
important predictors and provides a separate risk prediction model for each
cohort. It allows sharing information between cohorts to increase power by
assuming a graph linking predictors within and across different cohorts. The
graph helps to identify pathways of functionally related genes and genes that
are simultaneously prognostic in different cohorts. Results demonstrate that
our proposed approach is superior to the standard approaches in terms of
prediction performance and increased power in variable selection when the
sample size is small.Comment: under review, 19 pages, 10 figure

Exceptional Response to Pembrolizumab in a Mismatch Repair-Deficient Aggressive Prostate Cancer with Somatic EPCAM, MSH2, and MSH6 Co-Deletion: A Case Report.
Mismatch repair-deficient (dMMR) prostate cancer (PCa) is a rare (1-5%) but highly actionable molecular subgroup of PCa, vulnerable to immune checkpoint inhibitors. Our case of sporadic dMMR PCa due to large monoallelic co-deletion of EPCAM, MSH2, and MSH6 features a clinically aggressive disease presentation and a major response to pembrolizumab. We report a 65-year-old patient with primary metastatic PCa, Gleason score 5 + 5 = 10, with penile and lymph node metastases at diagnosis. Patient showed rapid progression on first-line ADT and enzalutamide. Tumor next-generation sequencing (NGS) revealed microsatellite instability and a tumor mutational burden of 40.8 mutations/megabase. Immunohistochemistry showed co-loss of MSH2 and MSH6. Review of NGS row data confirmed large monoallelic deletion in chromosome 2p, including EPCAM, MSH2, and MSH6. No germline alterations in mismatch repair genes were detected. Patient showed excellent response to pembrolizumab, which is still ongoing. We conclude that early molecular tumor profiling is essential to enable personalized management of advanced PCa, especially in patients with aggressive or atypical disease course
Probe dependence of allosteric enhancers on the binding affinity of adenosine A1âreceptor agonists at rat and human A1âreceptors measured using NanoBRET
Background and Purpose: Adenosine is a local mediator that regulates a number of physiological and pathological processes via activation of adenosine A1âreceptors. The activity of adenosine can be regulated at the level of its target receptor via drugs that bind to an allosteric site on the A1âreceptor. Here, we have investigated the species and probe dependence of two allosteric modulators on the binding characteristics of fluorescent and nonfluorescent A1âreceptor agonists. Experimental Approach: A Nanoâluciferase (Nluc) BRET (NanoBRET) methodology was used. This used Nâterminal Nlucâtagged A1âreceptors expressed in HEK293T cells in conjunction with both fluorescent A1âreceptor agonists (adenosine and NECA analogues) and a fluorescent antagonist CA200645.Key Results: PD 81,723 and VCP171 elicited positive allosteric effects on the binding affinity of orthosteric agonists at both the rat and human A1âreceptors that showed clear probe dependence. Thus, the allosteric effect on the highly selective partial agonist capadenoson was much less marked than for the full agonists NECA, adenosine, and CCPA in both species. VCP171 and, to a lesser extent, PD 81,723, also increased the specific binding of three fluorescent A1âreceptor agonists in a speciesâdependent manner that involved increases in Bmax and pKD.Conclusions and Implications: These results demonstrate the power of the NanoBRET ligandâbinding approach to study the effect of allosteric ligands on the binding of fluorescent agonists to the adenosine A1âreceptor in intact living cells. Furthermore, our studies suggest that VCP171 and PD 81,723 may switch a proportion of A1âreceptors to an active agonist conformation (R*)
Improvement of pain experience and changes in heart rate variability through music-imaginative pain treatment
Music-imaginative Pain Treatment (MIPT) is a form of music therapy addressing pain experience and affective attitudes toward pain. It includes two self-composed music pieces: one dedicated to the pain experience (pain music, PM) and the other to healing imagination (healing music, HM). Our non-experimental study addresses patients with chronic somatoform pain disorders participating in MIPT. The goal is to gain insight into the direct effect mechanisms of MIPT by combining outcome measures on both the objective physiological and subjective perception levels. The research questions are directed toward changes in pain experience and heart rate variability and their correlations. Thirty-seven hospitalized patients with chronic or somatoform pain disorders receiving MIPT participated in this study. Demographic data and psychometric measures (Symptom Check List SCL90, Childhood Trauma Questionnaire CTQ) were collected to characterize the sample. Subjective pain experience was measured by McGill Pain Questionnaire (SF-MPQ), and Heart Rate Variability by 24 h-ECG. Data analysis shows a reduction of reported pain from MT1 = 19.1 (SD = 7.3) to MT2 = 10.6 (SD = 8.0) in all dimensions of the SF-MPQ. HRV analyses shows a reduced absolute power during PM and HM, while a relative shift in the autonomic system toward higher vagal activity appears during HM. Significant correlations between HRV and MPQ could not be calculated. Findings are interpreted as a physiological correlate to the psychological processes of the patients. Future studies with more participants, a control-group design, and the integration of medium- and long-term effects are recommended
Biofunctionalization of annealed nanodiamonds
In the last decades nanodiamonds have received special attention from the scientific community as a new carbon material with unique properties. Along with the macrosize diamond, those nanoparticles exhibit an exceptional hardness and sp3-core whereas, the size allows different applications. Among others they can be applied in new composites, lubrication oils, polishing and electronic materials, and drug delivery, biolabeling and bioimaging systems.
To improve biocompatibility of diamond nanocrystals the surface functionalization is a favorable solution. The nanodiamonds the authors used were obtained by detonation synthesis and for this possess several functional groups on the surface. Further modifications require a homogeneous surface. In this approach a thermal methodology was used to remove the functional groups in order to produce an uniform carbon surface. The chosen biomolecules were phenylalanine, glutathione, biotin and O-phosphorylethanolamine to increase the biological suitability.
The thermal annealing process was performed at three different temperatures: 750 °C, 900 °C and 1100 °C, under nitrogen flow to prevent oxidation. In the end of the procedure, samples were characterized by infrared spectroscopy, thermogravimetric analysis and transmission electron microscopy. The results revealed a significant decrease in functional groups for all temperatures. At 1100 °C onion like carbon can be identified in our sample, proving of a successful graphitization of the nanodiamonds. For biofunctionalization different approaches were applied: 1) carboxylation and further peptide bonding; 2) hydroxylation, silanization and further peptide bonding; 3) click chemistry, as depicted in figure 2. Success of the modification is verified by infrared spectroscopy and thermogravimetric analysis which evidence the success of the surface modification
CCR8 leads to eosinophil migration and regulates neutrophil migration in murine allergic enteritis
Allergic enteritis (AE) is a gastrointestinal form of food allergy. This study aimed to elucidate cellular and molecular mechanisms of AE using a murine model. To induce AE, BALB/c wild type (WT) mice received intraperitoneal sensitization with ovalbumin (an egg white allergen) plus ALUM and feeding an egg white (EW) diet. Microarray analysis showed enhanced gene expression of CC chemokine receptor (CCR) 8 and its ligand, chemokine CC motif ligand (CCL) 1 in the inflamed jejunum. Histological and FACS analysis showed that CCR8 knock out (KO) mice exhibited slightly less inflammatory features, reduced eosinophil accumulation but accelerated neutrophil accumulation in the jejunums, when compared to WT mice. The concentrations of an eosinophil chemoattractant CCL11 (eotaxin-1), but not of IL-5, were reduced in intestinal homogenates of CCR8KO mice, suggesting an indirect involvement of CCR8 in eosinophil accumulation in AE sites by inducing CCL11 expression. The potential of CCR8 antagonists to treat allergic asthma has been discussed. However, our results suggest that CCR8 blockade may promote neutrophil accumulation in the inflamed intestinal tissues, and not be a suitable therapeutic target for AE, despite the potential to reduce eosinophil accumulation. This study advances our knowledge to establish effective anti-inflammatory strategies in AE treatment.Fil: Blanco-PĂ©rez, Frank. Paul-ehrlich-institut;Fil: Kato, Yoichiro.
