Moniz, AB, Krings B-J.  2016.  Robots Working with Humans or Humans Working with Robots? Searching for Social Dimensions in New Human-Robot Interaction in Industry Societies. 2016(6):23. AbstractWebsite

The focus of the following article is on the use of new robotic systems in the manufacturing industry with respect to the social dimension. Since “intuitive” human–machine interaction (HMI) in robotic systems becomes a significant objective of technical progress, new models of work organization are needed. This hypothesis will be investigated through the following two aims: The first aim is to identify relevant research questions related to the potential use of robotic systems in different systems of work organization at the manufacturing shop-floor level. The second aim is to discuss the conceptualization of (old) organizational problems of human–robot interaction (HRI). In this context, the article reflects on the limits of cognitive and perceptual workload for robot operators in complex working systems. This will be particularly relevant whenever more robots with different “roles” are to be increasingly used in the manufacturing industry. The integration of such complex socio-technical systems needs further empirical and conceptual research with regard to “social” aspects of the technical dimension. Future research should, therefore, also integrate economic and societal issues to understand the full dimensions of new human–robot interaction in industry today.

Krings, B-J, Rodriguez H, Schleisiek A.  2016.  Scientific knowledge and the transgression of boundaries. , Wiesbaden: Springer VS Abstract

The aim of this book is to understand and critically appraise science-based transgression dynamics in their whole complexity. It includes contributions from experts with different disciplinary backgrounds, such as philosophy, history and sociology. Thus, it is in itself an example of boundary transgession. Scientific disciplines and their objects have tended to be seen as permanent and distinct. However, science is better conceived as an activity that constantly surpasses, erases and rebuilds all kinds of boundaries, either disciplinary, socio-ethical or ecological. This transgressive capacity, a characteristic trait of science and its applications, defines us as "knowledge societies." However, scientific and technological developments are also sources of serious environmental and social concerns.

Oncotarget . AbstractWebsite

Dendritic cells (DCs) hold promise for anti-cancer immunotherapy. However, clinically, their efficiency is limited and novel strategies to improve DC-mediated anti-tumor responses are needed. Human DCs display high content of sialic acids, which inhibits their maturation and co-stimulation capacity. Here, we aimed to understand whether exogenous desialylation of DCs improves their anti-tumor immunity. Compared to fully sialylated DCs, desialylated human DCs loaded with tumor-antigens showed enhanced ability to induce autologous T cells to proliferate, to secrete Th1 cytokines, and to specifically induce tumor cell apoptosis. Desialylated DCs showed an increased expression of MHC-I and -II, co-stimulatory molecules and an augmented secretion of IL-12. Desialylated HLA-A*02:01 DCs pulsed with gp100 peptides displayed enhanced peptide presentation through MHC-I, resulting in higher activation ofgp100280–288 specific CD8+ cytotoxic T cells. Desialylated murine DCs also exhibited increased MHC and co-stimulatory molecules and higher antigen cross-presentation via MHC-I. These DCs showed higher ability to activate antigen-specific CD4+ and CD8+ T cells, and to specifically induce tumor cell apoptosis. Collectively, our data demonstrates that desialylation improves DCs’ ability to elicit T cell-mediated anti-tumor activity, due to increased MHC-I expression and higher antigen presentation via MHC-I. Sialidase treatment of DCs may represent a technology to improve the efficacy of antigen loaded-DC-based vaccines for anti-cancer immunotherapy.

João, C, Almeida R, Silva JC, Borges JP.  2016.  A simple sol-gel route to the construction of hydroxyapatite inverted colloidal crystals for bone tissue engineering. Materials Letters. 185:407-410. AbstractWebsite

Hydroxyapatite (HAp) scaffolds with uniform pore size and interconnected pore network were constructed based on the inverted colloidal crystal (ICC) geometry and a simple sol-gel formulation. Monodisperse polystyrene microspheres were self-assembled and annealed into a hexagonal close packed structure. HAp sol-gel was infiltrated in this template followed by thermal treatment for simultaneous HAp matrix sintering and polymeric colloidal crystal calcination. The resultant ICC scaffolds exhibit an ordered architecture that was able to offer a favorable environment for human osteoblasts adhesion and proliferation, an essential feature for bone ingrowth in tissue engineering applications.

Retroviral vectors gained popularity toward other viral vectors as they integrate their genome into hosts' genome, a characteristic required for the modification of stem cells. However, the production of viable particles for gene therapy is hampered by the low ratio of infectious to non-infectious viral particles after purification, low titers and limited number of competent viral receptors. We have developed de novo two fully synthetic triazine-based ligands that can selectively bind retroviral particles pseudotyped with amphotropic murine leukemia virus envelope (AMPHO4070A). A 78-membered library of triazine-based ligands was designed in silico and was virtually screened against the modeled structure of the AMPHO4070A protein. Ligands displaying the highest energy of binding were synthesized on cross-linked agarose and experimentally tested. Adsorbents containing ligands A5A10 and A10A11 showed selectivity toward viral particles containing the target protein (VLP-AMPHO), binding 19 ± 5 $μ$g/g support and 47 ± 13 $μ$g/g support, respectively. The elution conditions for both ligands were mild and with high recovery yields (80-100{%}), in comparison with common purification practices. These results were based on a lab-scale experimental setting with VLP integrity being confirmed through TEM. In particular, the elution buffer containing 12 mM imidazole allowed the recovery of intact amphotropic viral particles.

Krings, B-J.  2016.  Strategien der Individualisierung. Neue Konzepte und Befunde zur soziologischen Individualisierungsthese. , Bielefeld: transcript Abstract

Der Begriff der Individualisierung trägt in der Regel negative Konnotationen: sei es im Hinblick auf eine zunehmende Vereinzelung und Vereinsamung von Individuen oder hinsichtlich der Zunahme egoistisch anmutender Handlungen von Menschen, die das Gemeinwohl aus dem Blick verlieren. Prozesse der Individualisierung werden daher häufig als Bedrohung für die Konstituierung moderner Gesellschaften diskutiert. Diese Studie hingegen präsentiert eine neue Lesart der Individualisierung. Orientiert an Niklas Luhmanns Arbeiten und gestützt auf Ergebnisse einer empirischen Studie legt Bettina-Johanna Krings eine soziologische Betrachtung vor, die die Aufforderung zur Individualisierung als eine notwendige Herausforderung in modernen Gesellschaften interpretiert.

Ma, Z, Zhang B, da Silva FGMC, Mendo AS, Silva J, Baptista PV, Fernandes AR, Pombeiro AJL.  2016.  Synthesis, Characterization, Thermal Properties and Antiproliferative Potential of Copper(II) 4′-phenyl-terpyridine Compounds. Dalton Transations. (12) AbstractWebsite

Reactions between 4′-phenyl-terpyridine (L) and several Cu(II) salts (p-toluenesulfonate, benzoate and o-, m- or p-hydroxybenzoate) led to the formation of [Cu(p-SO3C6H4CH3)L(H2O)2](p-SO3C6H4CH3) (1), [Cu(OCOPh)2L] (2), [Cu(o-OCOC6H4OH)2L] (3), [Cu(m-OCOC6H4OH)2L]·MeOH (4·MeOH) and [Cu(p-OCOC6H4OH)2L]·2H2O (5·2H2O), which were characterized by elemental and TG-DTA analyses, ESI-MS, IR spectroscopy and single crystal X-ray diffraction, as well as by conductivimetry. In all structures the Cu atoms present N3O3 octahedral coordination geometries, which, in 2–5, are highly distorted as a result of the chelating-bidentate mode of one of the carboxylate ligands. Intermolecular π⋯π stacking interactions could also be found in 2–5 (in the 3.569–3.651 Å range and involving solely the pyridyl rings). Medium–strong hydrogen bond interactions lead to infinite 1D chains (in 1 and 4) and to an infinite 2D network (in 5). Compounds 1 and 4 show high in vitro cytotoxicity towards HCT116 colorectal carcinoma and HepG2 hepatocellular carcinoma cell lines. The antiproliferative potential of compound 1 is due to an increase of the apoptotic process that was confirmed by Hoechst staining, flow cytometry and RT-qPCR. All compounds able to non-covalently intercalate the DNA helix and induce in vitro pDNA double-strand breaks in the absence of H2O2. Concerning compound 1, the hydroxyl radical and singlet oxygen do not appear to be involved in the pDNA cleavage process and the fact that this cleavage also occurs in the absence of molecular oxygen points to a hydrolytic mechanism of cleavage.

Muñoz-ruiz, M, Ribot JC, Grosso AR, Gonçalves-sousa N, Pamplona A, Pennington DJ, Regueiro JR, Fernández-malavé E, Silva-santos B.  2016.  TCR signal strength controls thymic differentiation of discrete proinflammatory γδT cell subsets. Nature immunology. , Number April AbstractWebsite

The mouse thymus produces discrete γδ T cell subsets that make either interferon-γ (IFN-γ) or interleukin 17 (IL-17), but the role of the T cell antigen receptor (TCR) in this developmental process remains controversial. Here we show that Cd3g(+/-) Cd3d(+/-) (CD3 double-haploinsufficient (CD3DH)) mice have reduced TCR expression and signaling strength on γδ T cells. CD3DH mice had normal numbers and phenotypes of αβ thymocyte subsets, but impaired differentiation of fetal Vγ6(+) (but not Vγ4(+)) IL-17-producing γδ T cells and a marked depletion of IFN-γ-producing CD122(+) NK1.1(+) γδ T cells throughout ontogeny. Adult CD3DH mice showed reduced peripheral IFN-γ(+) γδ T cells and were resistant to experimental cerebral malaria. Thus, TCR signal strength within specific thymic developmental windows is a major determinant of the generation of proinflammatory γδ T cell subsets and their impact on pathophysiology.

Soares, PIP, Machado D, Laia C, Pereira L, Coutinho J, Ferreira I, Novo C, Borges JP.  2016.  Thermal and magnetic properties of chitosan-iron oxide nanoparticles. Carbohydrate polymers. 149:382-390. AbstractWebsite

Chitosan is a biopolymer widely used for biomedical applications such as drug delivery systems, wound healing, and tissue engineering. Chitosan can be used as coating for other types of materials such as iron oxide nanoparticles, improving its biocompatibility while extending its range of applications.
In this work iron oxide nanoparticles (Fe3O4 NPs) produced by chemical precipitation and thermal decomposition and coated with chitosan with different molecular weights were studied. Basic characterization on bare and chitosan-Fe3O4 NPs was performed demonstrating that chitosan does not affect the crystallinity, chemical composition, and superparamagnetic properties of the Fe3O4 NPs, and also the incorporation of Fe3O4 NPs into chitosan nanoparticles increases the later hydrodynamic diameter without compromising its physical and chemical properties. The nano-composite was tested for magnetic hyperthermia by applying an alternating current magnetic field to the samples demonstrating that the heating ability of the Fe3O4 NPs was not significantly affected by chitosan.

Soares, PIP, Sousa AI, Ferreira I, Novo C, Borges JB.  2016.  Towards the development of multifunctional chitosan-based iron oxide nanoparticles: Optimization and modelling of doxorubicin release. Carbohydrate Polymers. 153:212-221. AbstractWebsite

In the present work composite nanoparticles with a magnetic core and a chitosan-based shell were produced as drug delivery systems for doxorubicin (DOX). The results show that composite nanoparticles with a hydrodynamic diameter within the nanometric range are able to encapsulate more DOX than polymeric nanoparticles alone corresponding also to a higher drug release. Moreover the synthesis method of the iron oxide nanoparticles influences the total amount of DOX released and a high content of iron oxide nanoparticles inhibits DOX release. The modelling of the experimental results revealed a release mechanism dominated by Fickian diffusion.
