Selection of an aptamer and development of a genetic device to control mRNA stability in response to light
(2022-02-09)
Artificial autocatalytic RNA molecules, so-called aptazymes, are utilized as genetic devices to study and influence biological processes. These genetic devices consist of the autocatalytic RNA part, the ribozyme, and a ...
The role of Sphingosine-1-phosphate receptors in adipocytes and adipose tissues
(2021-01-19)
Obesity is a worldwide health issue with increasing numbers of patients every year. Moreover, the prevalence of obesity gives rise to related cardiovascular diseases and various other comorbidities influencing quality of ...
Loss of Inhibitory CD33 Signaling Results in Increased Microglial Activation
(2021-06-23)
CD33 is expressed on immune cells of myeloid origin, such as macrophages and microglia. Upon activation, CD33 recruits and activates protein tyrosine phosphatases, which results in attenuation of the activatory signaling ...
Geographical perspective on antibiotic resistance in a metropolitan sewershed: Investigating socio-spatial hotspots of antibiotic use and antibiotic-resistant bacteria in Dortmund, Germany
(2022-02-08)
Antibiotic resistance is a serious global health threat, driven by the inadequate and excessive use of antibiotics. Environmental compartments, particularly wastewater, occupy a pivotal role in the spread of antibiotic-resistant ......
Antibiotikaresistenzen sind eine schwerwiegende Gesundheitsbedrohung, verursacht durch unsachgemäßen und exzessiven Antibiotikaeinsatz als einer der treibenden Hauptfaktoren. Umweltkompartimente, insbesondere Abwasser, ......
Antibiotikaresistenzen sind eine schwerwiegende Gesundheitsbedrohung, verursacht durch unsachgemäßen und exzessiven Antibiotikaeinsatz als einer der treibenden Hauptfaktoren. Umweltkompartimente, insbesondere Abwasser, ......
Simulation of Bone Remodeling Process around Dental Implant During the Healing Period
(2021-07-05)
This interdisciplinary thesis deals with the numerical investigation of bone remodeling around dental implants during the healing period with regard to biomechanical aspects. The aim of the study was to develop algorithms ...
Eosinophil Extracellular DNA Trap Cell Death (EETosis) occurs as a life-cycle stage-specific response to filariae
(2020-06-25)
Filarial nematodes represent a great burden of human morbidity causing diseases like onchocerciasis and lymphatic filariasis. The lack of a vaccination and a short-term therapy with a macrofilaricidal effect hampers the ......
Acetylcholine mediates protective immune responses against the rodent filarial nematode Litomosoides sigmodontis
(2022-02-22)
Tropical infectious diseases are caused by parasitic helminths, such as lymphatic filariasis and onchocerciasis (river blindness). Filariae have the ability to modulate the immune response of their host in order to be ......
GPR183 Expression on Pulmonary Conventional Dendritic Cell Type 2 Dictates Subtissular Localisation and Instructs Their Survival via the Thymic Stromal Lymphopoietin (TSLP) – TSLP Receptor (TSLPR) Axis
(2021-07-06)
Introduction: G protein-coupled receptor 183 (GPR183) is a chemotactic receptor, highly expressed by immune cells. Upon activation by its ligand, 7a,25-dihydroxycholesterol (7a,25-OHC), GPR183 activates downstream signals ......
Design, assembly, and operation of a self-regulating DNA rotaxane linear actuator
(2022-04-07)
DNA is not only the carrier of genetic information but also an excellent bottom-up material for constructing nanostructures due to its high degree of programmability. Interlocked DNA nanostructures have a potential use as ...
Low Endotoxin Recovery: Wiederfindung und pyrogene Aktivität von Endotoxinen in pharmazeutischen Produkten
(2021-08-06)
Eine zuverlässige Überwachung bakterieller Kontaminationen ist entscheidend für die Herstellung und Sicherheit biopharmazeutischer Produkte. Die mikrobielle Sicherheit wird in der Regel (zusätzlich zu Sterilitätstests und ...
