The overall theme of this thesis is to complement the electrochemical data acquired in fuel cell research with in situ X-ray photoelectron spectroscopy (XPS) and soft X-ray absorption spectroscopy (XAS).

Details kunnen zien van een zieke of gezonde cel, dat is mogelijk met de supermicroscoop van het consortium Cyttron. Niet alleen de microscoop is vernieuwend in zijn soort: ook de vorm waarop de partijen samenwerken past in de huidige tijd. “Toegang tot elkaars techniek, daar draait het om in ons samenwerkingsverband”,…

De komende drie jaar gaan 92 studenten en wetenschappers van de Universiteit Leiden en hun partneruniversiteiten samen stappen zetten in onderzoek en onderwijs: alle veertien projecten die de Leidse universiteit indiende bij het International Credit Mobility-programma van de EU zijn gehonoreerd. Drie…

Met de nodige maatregelen starten onderzoekers hun werkzaamheden in verschillende laboratoria weer deels op. Het Leidse Cell Observatory is één van de plekken waar wetenschappers sinds 11 mei hun labwerk hervatten.

Een interuniversitair colloquium wordt georganiseerd aan de Universiteit Namen van 10-12 April 2024. Jonge onderzoekers die werken op het gebied van mobiliteit en interactie in de Maas-Rijn-regio tussen de negende en vijftiende eeuw worden aangemoedigd om een abstract van maximaal 500 woorden in te…

Healthy aging is one of the prime goals in today's society and atherosclerosis is among the greatest causes of morbidity in elderly. Cardiovascular disease patients receiving treatment are often of advanced aged and have an aged immune system, which limits translating experimental findings to the pa…

In this thesis, the role of mast cells in atherosclerosis and novel therapeutic strategies to inhibit atherosclerosis progression are discussed. The first part of the thesis specifically focuses on the relation between mast cells and advanced human atherosclerotic plaque characteristics.

Atherosclerosis is the most prominent underlying pathology of cardiovascular disease and an important cause of major adverse cardiovascular events.

This thesis describes our search to identify and understand possible regulatory mechanisms of integrin α6β4 in cell-matrix adhesion and intracelular signaling.

In this thesis, the researcher developed a nanosystem based on the metallophilic Interaction between cyclometalated complexes.

Streptomyces present a valuable platform for natural product discovery. Lugdunomycin is a novel angucycline-derived polyketide from Streptomyces sp QL37, with unprecedented skeleton and antimicrobial activity.

Bacterial biocatalysis constitutes a sustainable alternative for high-value chemicals production by enabling the utilization of renewable feedstocks.

This dissertation combines the use of defined microenvironments, high-resolution fluorescence microscopy, and time-resolved analysis, to study intracellular and cellular motility.

Hoe worden nachtruimtes verbeeld, geproduceerd, ervaren en verteld door migrantengemeenschappen in Europa? Dit onderzoeksproject onderzoekt deze vraag in acht Europese steden: Aarhus, Amsterdam, Berlijn, Cork, Galway, Lissabon, Londen en Rotterdam.

The human body consists of hundreds, perhaps thousands of different types of cells, each with different morphologies and functions, despite having the same genome.

Reducing greenhouse gas emissions is one of the most pressing challenges that humanity faces in the coming decades.

In summary, the collective results described in this thesis show that nanoparticulate vaccines can be delivered intradermally by coated and hollow microneedles and evoke antigen-specific immune responses.

Particles are omnipresent in biopharmaceutical products. In protein-based therapeutics such particles are generally associated with impurities, either derived from the drug product itself (e.g. protein aggregates), or from extrinsic contaminations (e.g. cellulose fibers).

In eight chapters, the thesis of Rafaël Vos covers the effect of temperature and pressure on the electrochemical CO2 reduction.

Single-Molecule Microscopy (SMM) techniques constitute a group of powerful imaging tools that enable researchers to study the dynamic behavior of individual molecules.

Despite the fact that gold nanoparticles (GNPs) are one of the most studied nanoparticles, there is still a necessity for new approaches allowing for effective protective coating to enable wider use of GNPs in biomedical applications.

In this thesis, we aimed to better understand the underlying mechanisms involved in TNBC progression and metastasis formation and discover new targets to reduce breast cancer related deaths.

In this thesis, we used genetically engineered mouse models and a variety of cell-culture based assays to identify genes and pathways that are involved in the development and treatment of invasive lobular carcinoma (ILC).

This thesis investigates how cell shape and collective behavior influence the dynamics and structure of biological tissues, which are crucial for understanding processes like embryonic development, tissue regeneration, and metastasis.

Cardiovascular diseases are a leading cause of death worldwide, and better models are urgently needed for disease progression studies and drug development.

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.
