We present a new strategy for the fabrication of artificial skeletal muscle tissue with functional morphologies based on an innovative 3D bioprinting approach. The methodology is microfluidic printing head coupled to co-axial needle extruder high-resolution hydrogel fibers laden precursor cells (C2C12). To promote myogenic differentiation, we formulated tailored bioink photocurable semi-synthetic biopolymer (PEG-Fibrinogen) encapsulating into constructs composed aligned fibers. After 3-5...
In this work we demonstrate how to print 3D biomimetic hydrogel scaffolds for cartilage tissue engineering with high cell density (>10(7) cells ml(-1)), viability (85 ÷ 90%) and printing resolution (≈100 μm) through a two coaxial-needles system. The were composed of modified biopolymers present in the extracellular matrix (ECM) cartilage, namely gelatin methacrylamide (GelMA), chondroitin sulfate amino ethyl methacrylate (CS-AEMA) hyaluronic acid (HAMA). polymers used prepare three...
Osteochondral (OC) tissue is a biphasic material comprised of articular cartilage integrated atop subchondral bone. Damage to this highly problematic, owing its intrinsic inability regenerate functional in response trauma or disease. Further, the function largely conferred by compartmentalized zonal microstructure and composition. Current clinical treatments fail new that recapitulates structure. Consequently, regenerated often lacks long-term stability. To address growing problem, we...
Gelatin methacrylate (GelMA) is an inexpensive, photocrosslinkable, cell-responsive hydrogel which has drawn attention for a wide range of tissue engineering applications. The potential GelMA scaffolds was demonstrated to be tunable different (TE) applications through modifying the polymer concentration, methacrylation degree, or UV light intensity. Despite promising results hydrogels in engineering, influence concentration bone (BTE) not established yet. Thus, this study, we have effect on...
On several paintings of James Ensor (1860−1949), a gradual fading originally bright yellow areas, painted with the pigment cadmium (CdS), is observed. Additionally, in some areas exposed to light, formation small white-colored globules on top original paint surface In this paper chemical transformation leading color change and elucidated. Microscopic X-ray absorption near-edge spectroscopy (μ-XANES) experiments show that sulfur, present sulfidic form (S2−), oxidized during sulfate (S6+)....
Over the past years a number of studies have described instability pigment cadmium yellow (CdS). In previous paper we shown how sulfide on paintings by James Ensor oxidizes to CdSO(4)·H(2)O. The degradation process gives rise fading bright color and formation disfiguring white crystals that are present paint surface in approximately 50 μm sized globular agglomerations. Here, study painting "Flowers blue vase" Vincent van Gogh. This differs from case fact (a) varnish was superimposed onto...
One promising strategy to reconstruct osteochondral defects relies on 3D bioprinted three-zonal structures comprised of hyaline cartilage, calcified and subchondral bone. So far, several studies have pursued the regeneration either cartilage or bone in vitro while-despite its key role region-only few them targeted layer.

Optical photothermal infrared (O-PTIR) is a recently developed molecular spectroscopy technique that allows to noninvasively obtain chemical information on organic and inorganic samples at submicrometric scale. The high spatial resolution (≈450 nm), lack of sample preparation, comparability the spectral results traditional Fourier transform make it promising candidate for analysis cultural heritage. In this work, potential O-PTIR noninvasive characterization small heritage objects (few cubic...

The capacity of bone grafts to repair critical size defects can be greatly enhanced by the delivery mesenchymal stem cells (MSCs). Adipose tissue is considered most effective source MSCs (ADSCs); however, efficiency regeneration using undifferentiated ADSCs low. Therefore, this study proposes scaffolds based on polycaprolactone (PCL), which widely a suitable MSC system, were used as three-dimensional (3D) culture environment promoting osteogenic differentiation ADSCs. PCL enriched with 5%...
One promising strategy to reconstruct bone defects relies on 3D printed porous structures.
