Foot orientation affects muscle activation levels of ankle stabilizers in a single-legged balance board protocol Ghent University
Crim1 maintains retinal vascular stability during development by regulating endothelial cell Vegfa autocrine signaling KU Leuven
Angiogenesis defines the process in which new vessels grow from existing vessels. Using the mouse retina as a model system, we show that cysteine-rich motor neuron 1 (Crim1), a type I transmembrane protein, is highly expressed in angiogenic endothelial cells. Conditional deletion of the Crim1 gene in vascular endothelial cells (VECs) causes delayed vessel expansion and reduced vessel density. Based on known Vegfa binding by Crim1 and Crim1 ...
Probabilistic Visibility Evaluation using Geometry Proxies KU Leuven
Evaluating the visibility between two points is a fundamental problem for ray-tracing and path-tracing algorithms. Ideally, visibility computations are organized such that a minimum number of geometric primitives need to be checked for each ray. Replacing complex geometric shapes by a simpler set of primitives is one strategy to control the amount of intersection calculations. However, approximating the original geometry introduces inaccuracies ...
Interrelationships Between Anthropometric Variables and Overweight in Childhood and Adolescence KU Leuven
OBJECTIVES: To answer the questions: how does body mass index (BMI) correlate to five overweight related anthropometric variables during different ages in childhood, and which anthropometric variables contribute most to variation in BMI during childhood? METHODS: Data on BMI, height (H), sitting height (SH), waist circumference (WC), waist to height ratio (WHtR), waist to sitting height ratio (WSHtR), subscapular skinfold (SSF), and triceps ...
Single-cell force spectroscopy of pili-mediated adhesion KU Leuven University of Antwerp
Although bacterial pili are known to mediate cell adhesion to a variety of substrates, the molecular interactions behind this process are poorly understood. We report the direct measurement of the forces guiding pili-mediated adhesion, focusing on the medically important probiotic bacterium Lactobacillus rhamnosus GG (LGG). Using non-invasive single-cell force spectroscopy (SCFS), we quantify the adhesion forces between individual bacteria and ...
Scaling up comprehensive sexuality education in Nigeria : from national policy to nationwide application Ghent University
Nigeria is one of few countries that reports having translated national policies on school-based comprehensive sexuality education (CSE) into near-nationwide implementation. We analysed data using the World Health Organization-ExpandNet framework, which provides a systematic structure for planning and managing the scaling up of health innovations. We examined how Nigeria's nationwide programme was designed and executed. Since 2002, Nigeria has ...
Impact of the spatial and thematic resolution of Holocene anthropogenic land cover scenarios on modeled soil erosion and sediment delivery rates KU Leuven
Recent reconstructions of global Holocene vegetation may provide a powerful means to quantify long-term cumulative sediment fluxes induced by anthropogenic land cover changes. However, the former’s low spatial resolutions question their potential for use in geomorphic models, since sediment redistribution processes operate at much smaller scales. Furthermore, current land cover reconstructions often do not differentiate the typology of human ...
Worse than Death: The Non-Preservationist Foundations of Hobbes's Moral Philosophy KU Leuven
© 2014 by Koninklijke Brill NV, Leiden, The Netherlands. This article challenges the orthodoxy that Hobbes's laws of nature, considered as dictates of reason, ceaselessly oblige agents in virtue of the general desire for self-preservation. Hobbes is an internalist about reasons, who refuses reason independent motivational efficacy. The universal prescriptive force of natural law is instead grounded in some desire (or set of desires) which all ...
