Infectious Tolerance

2002

Regulatory CD4(+)CD25(+) T cells (Treg) are mandatory for maintaining immunologic self-tolerance. We demonstrate that the cell-cell contact-mediated suppression of conventional CD4(+) T cells by human CD25(+) Treg cells is fixation resistant, independent from membrane-bound TGF-beta but requires activation and protein synthesis of CD25(+) Treg cells. Coactivation of CD25(+) Treg cells with Treg cell-depleted CD4(+) T cells results in anergized CD4(+) T cells that in turn inhibit the activation of conventional, freshly isolated CD4(+) T helper (Th) cells. This infectious suppressive activity, transferred from CD25(+) Treg cells via cell contact, is cell contact-independent and partially medi…

Vulvodynia¿It Is Time to Accept a New Understanding from a Neurobiological Perspective

2021

Vulvodynia is one the most common causes of pain during sexual intercourse in premenopausal women. The burden of vulvodynia in a woman’s life can be devastating due to its consequences in the couple’s sexuality and intimacy, in activities of daily living, and psychological well-being. In recent decades, there has been considerable progress in the understanding of vulvar pain. The most significant change has been the differentiation of vulvar pain secondary to pathology or disease from vulvodynia. However, although it is currently proposed that vulvodynia should be considered as a primary chronic pain condition and, therefore, without an obvious identifiable cause, it is still believed that …

Use of stable isotopes to investigate dispersal of waste from fish farm as a function of hydrodynamics.

2006

Stable isotopes were used to examine differential effects of fish farm waste on the water column and sediments. To achieve this objective, we chose 3 marine fish farms located along the coast of Sicily (Mediterranean Sea) as point-source disturbances, and a control area. The hypothesis that carbon and nitrogen isotope composition of particulate (POM) and sedimentary (SOM) organic matter varied with increasing distance (from cages to 1000 m) was tested at 3 levels of hydrodynam- ics: low (mean velocity of current (MVC) ~12 cm s -1 ), intermediate (MVC ~22 cm s -1 ), and high (MVC ~40 cm s -1 ). Different isotopic signals from allochthonous (fish waste) over natural (phytoplankton, terrigenou…

Collegium Maius Building\nUniversity of Opole Rector’s insignia, commemorative medals and portraits

The Museum of University of Opole houses historical (1970) and current (2021) insignia of the rector’s office: chains, rings and scepters made of silver and decorated with precious stones. A frequent decorative motif is the eagle of the Piast dynasty(the first royal house of Poland) wearing a crown. It also stores commemorative medals in bronze or patinated bronze (size from 6 to 9 cm in diameter) that commemorate various jubilees – the University inauguration in 1994, the University tenth and twentieth anniversaries in 2004 and 2014 respectively. It also exhibits originals and replicas of oil paintings of University rectors in ceremonial robes. It is also possible to see the commemorative …

Double-quantum nutations in a two-level spin system

1986

The transient oscillatory behavior of the nonlinear response of a two-level electron-spin system is experimentally investigated in a sample of glassy silica with ${E}_{1}^{\mathcal{'}}$ centers (S=(1/2)) at microwave frequency at T=4.2 K. The transient regime, excited by an intense step-modulated radiation tuned to double-quantum (DQ) resonance, is monitored by revealing the second-harmonic (SH) wave radiated by the spins undergoing DQ transitions. Time- and frequency-domain results show that the emitted SH wave has two components: the former, which vanishes at the DQ resonance, exhibits an overdamped transient regime, the latter consists of damped oscillations at a frequency which depends …

Integrated Activities for the High Energy Astrophysics Domain

High-energy astrophysics is the study of the most energetic and extreme processes in the universe, processes that are impossible to replicate in experiments here on Earth. These processes are associated with objects like exploding stars and supermassive black holes, and their understanding not only helps us answer fundamental questions about the origin and evolution of our cosmos but also fosters technological developments in other areas. Further, it prepares us to optimise space exploration expeditions for maximum impact. Teamwork is necessary for success and the EU-funded AHEAD2020 project is team building to achieve this. A key focus is integration of national efforts while enhancing foc…

Session details: Distributed systems: WT - web technologies track

2018

The Web is relentlessly evolving. Once a single interconnection of static, physically distributed content passively accessed by human users through personal computers, during the explosion of Web-based social networks the Web evolved into an environment allowing users worldwide to interact and collaborate to create user-generated content within many virtual communities. In this line, Web 2.0 is the umbrella term used to encompass several developments which followed, namely social networking sites and social media sites (e.g., Facebook), blogs, wikis, folksonomies (e.g. Flickr), video sharing sites (e.g., YouTube), Web applications ("apps"), collaborative platforms, and mashup applications. …

Zentrum für Schul-, Bildungs- und Hochschulforschung

The Center for School, Education, and Higher Education Research is a central research facility of Johannes Gutenberg-University, Mainz that is supported by the Ministerium für Wissenschaft, Weiterbildung und Kultur des Landes Rheinland-Pfalz (Ministry of Science, Further Education, and Culture of Rhineland-Palatinate). The center combines the different expertises of JGU in three pillars: School, education, and higher education research. It supports strategic networking, academic exchange among researchers and scholars, and thus contributes to profile building of the three pillars.

Research group Innovative diagnostic and therapeutical Developments in Solid Tumors

One of the main objectives of InDeST is to help in the development of new therapies and diagnostic methods in cancer. For this, they have a large clinical and research team. For almost a decade, there has been a significant increase in studies related to digestive tract cancer and its treatment, as shown by various clinical guidelines disseminated at a European and global level. Therefore, the development of new drugs and their testing in clinical trials is one of their main lines of research. InDeST also focus on the study and identification of new prognostic and predictive biomarkers using liquid biopsy, with particular interest in the analysis of circulating free tumor DNA (ctDNA) and ci…

Die Beeinflussung der Tuberkulincytolyse durch speciesgleiche Seren nach Vorbehandlung der Serum- und Zellspender

1966

Die Tuberculincytolyse mit Zellen Tb-sensibilisierter Meerschweinchen wird aufgehoben, wenn die Tiere 6 Tage vor der Zellgewinnung einmal mit einem Komplex aus Histamin und Globulin behandelt werden. Das Serum von Tieren, die lediglich den Histamin-Globulin-Komplex, nicht aber Tb-Material erhalten hatten, vermittelt den Cytolyseschutz nicht, Seren von Tieren, die 10 oder 20 Tage vorher nur mit Tb sensibilisiert worden waren und keinen oder nur einen geringen Middlebrook-Dubos-Titer besasen, heben den cellularen Cytolyseschutz auf, wenn sie verdunnt, nicht aber, wenn sie unverdunnt dem Reaktionsgemisch zugegeben werden.
