The Development of Dentin Microstructure Is Controlled by the Type of Adjacent Epithelium
(Wiley, 2022-02-01)Considerable amount of research has been focused on dentin mineralization, odontoblast differentiation, and their application in dental tissue engineering. However, very little is known about the differential role of ... -
Resolving complex cartilage structures in developmental biology via deep learning-based automatic segmentation of X-ray computed microtomography images
(NATURE PORTFOLIO, 2022-05-24)The complex shape of embryonic cartilage represents a true challenge for phenotyping and basic understanding of skeletal development. X-ray computed microtomography (mu CT) enables inspecting relevant tissues in all three ... -
Living in darkness: Exploring adaptation of Proteus anguinus in 3 dimensions by X-ray imaging
(Oxford University Press GigaScience, 2022-04-05)Background: Lightless caves can harbour a wide range of living organisms. Cave animals have evolved a set of morphological, physiological, and behavioural adaptations known as troglomorphisms, enabling their survival in ... -
Contour laser strategy and its benefits for lattice structure manufacturing by selective laser melting technology
(Elsevier, 2022-01-19)This paper deals with the research of the Selective Laser Melting (SLM) scanning strategy to produce lattice structures from AlSi10Mg powder material. Nowadays, most of the SLM end-users use the laser strategy and parameters ... -
Use of Micro-CT Imaging to Assess Ventral Mandibular Cortical Thickness and Volume in an Experimental Rodent Model With Chronic High-Phosphorus Intake
(Frontiers, 2021-12-09)Adverse effects of high dietary phosphorus on bone health have been observed in both animal and human studies. The aim of the investigation was to examine chronic effects of high phosphorus diet on the apical mandibular ... -
Chemical stability of tricalcium phosphate - iron composite during spark plasma sintering
(MDPI, 2018-09-01)Tricalcium phosphate (Ca3(PO4)2, TCP) is a wide-used ceramic as a bone filler material due to its good osteoconductivity property. Nevertheless, its poor mechanical properties does not allow its use for load-bearing ... -
Mechanochemical synthesis of mononuclear gold(I) halide complexes of diphosphine ligands with tuneable luminescent properties
(Royal Society of Chemistry, 2021-10-05)A mechanochemical method is reported for the synthesis of Au(diphos)X complexes of diphosphine (diphos = XantPhos and N-XantPhos) ligands and halide ions (X = Cl and I). The Au(XantPhos)X (1: X = Cl; 2: X = I) and ... -
Vibrations Analysis of the Fruit-Pedicel System of Coffea arabica var. Castillo Using Time-Frequency and Wavelets Techniques
(MDPI, 2021-10-01)Colombian coffee production is well-known, and selective manual harvesting plays a vital task in guaranteeing high ripe coffee fruit rates in this process, leading to its known worldwide aroma and flavor. To maintain this ... -
DUCT: Double Resin Casting followed by Micro-Computed Tomography for 3D Liver Analysis
(MYJoVE Corporation, 2021-09-28)The liver is the biggest internal organ in humans and mice, and high auto-fluorescence presents a significant challenge for assessing the three-dimensional (3D) architecture of the organ at the whole-organ level. Liver ... -
Triple-pulse LIBS: Laser-induced breakdown spectroscopy signal enhancement by combination of pre-ablation and re-heating laser pulses
(The Royal Society of Chemistry, 2020-02-01)The goal of this work is to examine the effect of a third additional laser pulse on orthogonal double-pulse laser-induced breakdown spectroscopy (DP LIBS). Namely, a pre-ablation laser pulse and re-heating laser pulse were ... -
Nerve-associated Schwann cell precursors contribute extracutaneous melanocytes to the heart, inner ear, supraorbital locations and brain meninges
(Springer, 2021-07-18)Melanocytes are pigmented cells residing mostly in the skin and hair follicles of vertebrates, where they contribute to colouration and protection against UV-B radiation. However, the spectrum of their functions reaches ... -
Spatiotemporal spectroscopic characterization of plasmas induced by non-orthogonal laser ablation
(Royal Society of Chemistry, 2020-11-23)Ablation geometry significantly affects the plasma parameters and the consequent spectroscopic observations in laser-induced breakdown spectroscopy. Nevertheless, plasmas induced by laser ablation under inclined incidence ... -
Analysis of neural crest-derived clones reveals novel aspects of facial development
(American Association for the Advancement of Science (AAAS), 2016-08-03)Cranial neural crest cells populate the future facial region and produce ectomesenchyme-derived tissues, such as cartilage, bone, dermis, smooth muscle, adipocytes, and many others. However, the contribution of individual ... -
