Hoogleraar dr. Marie Soressi werd door de Volkskrant geïnterviewd over de vermenging van DNA van neanderthalers en homo sapiens. Het lijkt er op dat dit vooral kwam door een combinatie van Neanderthaler mannen met homo sapiens vrouwen en vrijwel niet andersom.

Over several decades, a variety of computational methods for drug discovery have been proposed and applied in practice. With the accumulation of data and the development of machine learning methods, computational drug design methods have gradually shifted to a new paradigm, i.e. deep learning methods…

Een internationaal team van onderzoekers, onder leiding van de Leidse hoogleraar archeologie Marie Soressi en senior geneticus Matthias Meyer uit Leipzig, is erin geslaagd om het DNA van een vrouw uit een oude Noord-Euraziatische populatie te halen uit een 20.000 jaar oude hanger. Dit is de eerste keer…

This thesis presents the first synthetic peptides ADP-ribosylated on serine, threonine, tyrosine, arginine and cysteine.

CrO2, a half-metal ferromagnet, has shown great promise for superconducting spintronics applications for nearly two decades.

Nicotinamide adenine dinucleotide (NAD+) is the substrate used for the introduction of the ubiquitous and highly dynamic PTM in which either one or multiple adenosine diphosphate ribose (ADPr) moieties are covalently attached to a nucleophilic side chain of an specific amino acid in the target protein…

This thesis aims to enhance our understanding of galaxies by testing theoretical models of galaxy formation against observations, particularly in the cases of extreme systems which have been found to have an excess of baryonic mass in their central regions, in the form of either supermassive black holes…

Acute cardiovascular syndromes, including myocardial infarction or stroke, are the principal cause of death in the Western society. The main underlying pathology of cardiovascular diseases is atherosclerosis, which is caused by the accumulation of lipids and inflammatory cells in the vessel wall, in…

Pseudomonas Aeruginosa is a Gram-negative bacterium which can form biofilms, increasing its resistance against antibiotics and the host immune system. Polysaccharides are an integral part of this biofilm, one of these polysaccharides is called Psl. PslG is a glycosidase, able to cleave this polysaccharide,…

In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).

Increasing the efficiency of gene targeting (GT) as a genome editing tool in plants has been an important goal in plant biotechnology.

Acute cardiovascular clinical events such as myocardial infarction and cerebral stroke represent the major cause of death in Western societies. These pathologies are primarily resulting from atherosclerosis, a progressive condition characterized by the accumulation of lipids, immune cells, and fibrous…

Every organisms in the tree of life faces the same challenge: the length of its DNA exceeds the volume of the cell it needs to fit in. Several strategies have evolved to solve this problem, one of them being the expression of proteins that bind and organize the DNA.

G protein-coupled receptors (GPCRs), one of the largest families of membrane proteins, are responsive to a diverse set of physiological endogenous ligands including hormones and neurotransmitters.

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

Surface plasmons (SPs) are surface waves at the interface between a dielectric and a good metal, and are formed by the interaction between light and the free electrons at the metal-dielectric interface. They provide strong field confinement for optical fields, opening new possibilities for enhanced…

Aan het einde van de vijftiende eeuw werden twee intrigerende christelijke epische gedichten geschreven in Virgilisch Latijn door de dichters Sannazaro en Vida. Ze deden dit in overeenstemming met de wensen van de paus. Deze epische gedichten, zowel geprezen als bekritiseerd door tijdgenoten, worden…

In de aflevering 'Verborgen stad in de Amazone' schetst Alexander Geurds een beeld van de nederzettingen die in de jaren 70 voor het eerst werden ontdekt in het huidige Ecuador.

Luuk de Ligt heeft met zijn projectvoorstel 'An Empire of 2000 cities: urban networks and economic integration in the Roman Empire' een prestigieuze ERC Advanced Grant binnengehaald. Het project, dat in 2013 van start zal gaan, gaat plaats bieden aan in ieder geval zes aio's en twee postdocs.

In previous studies at our laboratory it was demonstrated that drug exposure of HepG2 cells can lead to an altered TNFα-induced NF-κB oscillatory phenotype, concurrent with a synergistically increased sensitivity for TNFα-induced apoptosis.

Given the accelerating appearance of antimicrobial resistance, there is an urgent need for more fundamental research into novel antibiotic strategies. The work in this thesis helps to address this global problem by developing new antibiotic compounds, inspired by the antibacterial mechanisms of the…
