Endotoxins are lipopolysaccharides anchored at the outer membrane of gram-negative bacteria. These pyrogenic compounds can be introduced in pharmaceutical products during their manufacture and could induce severe physiological reactions in humans. This is why endotoxins are dosed, in order to assure

The maturation of the human brain shows species-specific differences of neoteny when compared to lower mammals. This process encompass a time window that expands from late embryonic stages to early adolescence. Major features of brain maturation are the acquisition of phenotypic complex traits such

In contrast to human medicine, standard imaging techniques for cardiac interventions, namely fluoroscopy, CT and MRI, cannot be used in horses because the size of their thorax is too large for the gantry (CT and MRI) or results in insufficient detail (fluoroscopy). Therefore, echocardiography is

Severely burned skin can exhibit serious contractions that may negatively impact the mobility of joints of patients. The method deals with post-burn evolution of skin, in which one considers the balance of momentum, cells, collagen and chemokines. The balances are represented in terms of partial

UHDR irradiations show healthy tissue sparing effect known as the FLASH effect. Since 2014, the FLASH effect is investigated worldwide to understand how it works and how to trigger it. The FLASH effect is defined as an in vivo effect. However, in vivo models are often expensive and time-consuming.

Safety Assessment of Compounds after In Vitro Metabolic Conversion Using Zebrafish Eleuthero Embryos
Zebrafish-based platforms have recently emerged as a useful tool for toxicity testing as they combine the advantages of in vitro and in vivo methodologies. Nevertheless, the capacity to metabolically convert xenobiotics by zebrafish eleuthero embryos is supposedly low. To circumvent this concern, a

The spatiotemporal distribution of fluorescent compounds was examined during 48 h after immersion (10 µM) or microinjection (2 mg/kg) in the pericardial cavity (PC), intraperitoneally (IP) and yolk sac (IY) of 3 dpf zebrafsh eleuthero-embryos. By modelling the fluorescence of whole-body contours

Immersion treatment: zebrafish embryos at the two-cell stage were immersed in Danieau’s medium containing the compound. A compound concentration of 10 µM and DMSO concentration of 0.1% (v/v) in a volume of 5 mL was used per well (6-well-plates). At 72 h, the zebrafish medium containing the compound

The method is an approach to systematically study the impact of the nutrient microenvironment on the metabolism of effector CD8+ T cells, based on performing stable 13C isotope labeling measurements on in vitro-differentiated murine effector CD8+ T cells. Naive CD8+ T cells are isolated from mouse

Metabolomics and 13C tracer analysis are state-of-the-art techniques that allow determining the concentration of metabolites and the activity of metabolic pathways, respectively. Three dimensional (3D) cultures of cancer cells constitute an enriched in vitro environment that can be used to assay
