Skin Lipids: Localization of Ceramide and Fatty Acid in the Unit Cell of the Long Periodicity Phase
The lipid matrix of the skin's stratum corneum plays a key role in the barrier function, which protects the body from desiccation. The lipids that make up this matrix consist of ceramides, cholesterol, and free fatty acids, and can form two coexisting crystalline lamellar phases: the long periodicity…

Break-through in the genetic modification of plants
A collaboration between the IBL and LUMC has resulted in the discovery that the polymerase theta enzyme is essential for the integration of Agrobacterium T-DNA into the genome of plants. The finding means a break-through for the development of more efficient systems for targeted genome modification…

Even plants can have neighbour trouble
Restoring a natural plant environment on exhausted agricultural lands and in nature areas is difficult. We can speed this up by steering the soils towards the desired situation. This is what Martijn Bezemer, newly appointed Professor of Ecology of Plant-Microbe-Insect interactions at Leiden University’s…

Cancer chess: molecular insights into PARP inhibitor resistance
The clinical potential of applying synthetic lethality to cancer treatment is famously demonstrated by the BRCA1/PARP1 paradigm: a tumor specific defect in BRCA1 – a component of the DNA double-strand break (DSB) repair pathway homologous recombination (HR) – results in a remarkable sensitivity to PARP1…

Effect of Nanoparticles on Microbial Catabolism and Community Structure using Biolog techniques
1. To what extent do metallic NPs added to soil extractions change the activity, abundance, or community composition of microbes? 2. How do the effects of metallic NPs on soil microbes differ from the effects of the ions shedding from corresponding NPs?

Systems dermatology of inflammatory diseases
Inflammatory skin diseases such as psoriasis and atopic dermatitis can severely impact both the physical and social aspect of a patient’s life. Aberrant inflammatory responses are thought to be a major causative factor in these disorders, but an abundance of different factors contribute to the development…

Carbon atom reactivity with amorphous solid water: H2O-catalyzed formation of H2CO
We report new computational and experimental evidence of an efficient and astrochemically relevant formation route to formaldehyde (H2CO). This simplest carbonylic compound is central to the formation of complex organics in cold interstellar clouds and is generally regarded to be formed by the hydrogenation…
