(English version below)

Auch im kommenden Sommersemester wird wieder eine Ringvorlesung mit spannenden Beiträgen von Professor*innen der Abteilung angeboten. Teilnehmen können alle (professoralen und promovierenden) Mitglieder sowie Angehörige der Abteilung.

Wichtig:  wir benötigen eine Anmeldung zur Ringvorlesung (einmalig per Mail an die Koordination für das gesamte Semester)!

Wir freuen uns auf eine rege Teilnahme, sowohl von Promovierenden als auch gerne von Professor*innen!
 

Termine jeweils mittwochs, 10:00-11:30 Uhr, online.

Nanostructured Hybrid Biomaterials for multifaceted applications

Nanostructured hybrid biomaterials represent a cutting-edge class of materials that integrate functional biocompartments at nanoscales due to biomimetic principles. These types of structured hybrid compartments possess unique collective properties offering versatility and functionality across a broad spectrum of applications. For instance, the biomimetic compartments enable compatibility with biological systems, promoting cell adhesion, proliferation, and tissue regeneration. Besides, the nanostructured hybrid materials confer unique advantages, such as a high surface-to-volume ratio, precise control over morphology and surface properties, and enhanced mechanical, optical, and electrical characteristics. Therefore, they find utility in catalysis, environmental remediation, sensors, and energy conversion applications. The presentation also will elucidate fundamental approaches for the nanofabrication of structured hybrid materials at different dimensions and length scales toward their burgeoning applications across various domains. These will also include characterization techniques and highlight the challenges in nanomanufacturing with recent advancements to navigate through the multifaceted applications.

Sensorik - wie hilft sie uns Lebensmittel besser zu verstehen?

„Sensory Science is a scientific dicipline that evokes, quantifies, analyzes and interprets responses to the characteristics of stimuli perceived by the senses of smell, taste, sight, touch and hearing.“[1] lautet eine der am häufigsten zitierten Definitionen für Sensorik. Für Lebensmittel und Getränke, aber auch andere Konsumgüter wie Kosmetika, Sportbekleidung, Autos oder Uhren, ist es von entscheidender Bedeutung, nicht nur die chemische Zusammensetzung oder die physikalischen Eigenschaften der Produkte genau zu kennen, sondern auch zu verstehen, wie diese von Menschen wahrgenommen werden. Hierfür bietet die Sensorik wissenschaftliche Methoden, um genau diese Fragen zu beantworten. Das Spektrum sensorischer Untersuchungen umfasst dabei einen sehr weiten Bereich von Fragen, angefangen bei der Untersuchung, ob zwei Produkte tatsächlich anders aussehen, riechen oder schmecken, über das Finden von Unterschieden zwischen Produkten einer Produktgruppe in Bezug auf verschiedene Eigenschaften bis hin zu den Vorlieben der Konsument:innen in verschiedenen Teilen der Welt und den Gründen dafür.

In der Ringvorlesung soll anhand verschiedener Beispiele gezeigt werden, wie sensorische Untersuchungen das Verständnis von Lebensmitteln und Getränken verbessert: Schmeck Kaffee anders, wenn man ihn in Maschinen mit einem semi-konischen Korb oder einem runden Korb macht? Wie beeinflusst der Herstellungsprozess den Geschmack von Weißwein? Ist es einfacher, sensorische Eigenschaften von Kaffee oder Tequila zu beschreiben? Macht es einen Unterschied, welche Hafermilch ich kaufe? Schmecken Silvaner Weine aus derselben Region ähnlicher? Und spielt es eine Rolle, welche Chips ich zum Bier esse?

Stem cells, genome editing and neuropsychiatric disorders

The stem cell and genome editing fields in biomedicine have gained an incredible momentum with the recent approval of genome editing therapies and ongoing clinical trials of stem cell-based therapies for a variety of inherited and degenerative human diseases. Pluri- and multipotent stem cells of different origins and especially their cell derivatives with a particular tissue identity can be used for the replacement of lost cells. Examples for such applications are degenerative disorders such as Parkinson’s and Alzheimer’s Disease, age-related macula degeneration, and diabetes type I. Stem cells and their derivatives, however, are also used for the study of basic developmental processes in the otherwise inaccessible human embryo and fetus, the modeling of human diseases, and for drug and toxicity testing in an in vitro setting. In combination with nuclease-based genome editing, in particular CRISPR/Cas, stem cells are now applied for the cure of serious illnesses such as sickle cell anemia, beta-thalassemia, retinopathies and cancers. In this lecture, I will provide an overview of these themes on the background of our own research into dopamine-associated disorders, such as Parkinson’s Disease.

Multi-resistant bacteria in livestock farming: prevalence, relevance, measures for reduction

Germany is one of the countries with the highest detection rates of multi-resistant bacteria. Overall, 43.5% of the 46 pig breeding farms examined (EU average 14%) and 41.3% of the 155 production farms examined (EU average 26.9%) were affected. People exposed to pigs (farmers, veterinarians, slaughterhouse employees) are very often nasally colonized with MRSA CC398. Various studies have shown that around 80% of farmers in Germany are colonized with the pathogen. The results of a study on the persistence of MRSA colonization among farmers in pig farming in North Rhine-Westphalia and Lower Saxony show that the majority (50%) of farmers are persistently colonized, i.e. colonization persists even after prolonged absence from the animal house. "Farm animal-associated spa types", in particular t011 (10%) and t034 (6%) represent the third and fourth most common MRSA overall. Decolonization of persons with a connection to livestock farming has so far been unsuccessful in the long term, as these persons were recolonized with MRSA nasally, provided that MRSA was still detectable in the environment or animals in the animal stables. The sanitation or decontamination of livestock farms has so far been inadequate. New studies from the network project "#1HealthPREVENT" show that a reduction of these pathogens in livestock farming is possible. The latest results will be presented in the lecture.
 

______________________________________________________________________________

In the upcoming summer semester, we will once again offer a lecture series featuring exciting contributions from professors of the department. All members (professors and doctoral candidates) as well as associates of the department are welcome to participate. Important: Registration for the lecture series is required (one-time registration via email to the coordination office for the entire semester)!

For English speaking participants: each contribution will have either the slides or the presentation in English.

We look forward to active participation, both from doctoral candidates and also from professors!
 

All dates: Wednesdays, 10:00-11:30 am, online
