Wound healing is a complex process involving an integrated response by many different cell types and growth factors in order to achieve rapid restoration of skin architecture function. The present study evaluated the applicability chitosan hydrogel (CH) as wound dressing. Scanning electron microscopy analysis was used characterize CH morphology. Fibroblast cells isolated from rat were assess cytotoxicity hydrogel. able promote adhesion proliferation. Cell viability studies showed that its...
Nonparametric Bayesian methods are employed to constitute a mixture of low-rank Gaussians, for data x ∈ R <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">N</sup> that high dimension <i xmlns:xlink="http://www.w3.org/1999/xlink">N</i> but constrained reside in low-dimensional subregion . The number components and their rank inferred automatically from the data. resulting algorithm can be used learning manifolds reconstructing signals manifolds,...
pH is a vital physiological parameter that can be used for disease diagnosis and treatment as well in monitoring other biological processes. Metal/metal oxide based sensors have several advantages regarding their reliability, miniaturization, cost-effectiveness, which are critical characteristics vivo applications. In this work, WO3 nanoparticles were electrodeposited on flexible substrates over metal electrodes with sensing area of 1 mm(2). These show sensitivity -56.7 ± 1.3 mV/pH, wide...
ABSTRACT The electrospinning of polycaprolactone (PCL) dissolved in glacial acetic acid and the characterization resultant nonwoven fiber mats is reported this work. For comparison purposes, PCL were also obtained by polymer chloroform. Given processing parameters chosen, results show that 14 17 wt % solutions are not viscous enough yield beaded fibers, 20 23 give rise to high quality fibers 26 mostly irregular fused fibers. highly porous, retain tensile strain PCL, semicrystalline. Cells...
Polymeric scaffolds incorporating plant-derived compounds, produced by electrospinning, have attracted attention in the field of skin tissue engineering. This study evaluates sustained antioxidant activity polycaprolactone (PCL)/gelatin nanofibers prepared electrospinning and loaded liposomes epigallocatechin-3-gallate (EGCG), a strong antibacterial molecule found green tea, that significantly accelerates wound-healing process. The morphology structural properties membranes were...
The non-surgical treatments are being required to reconstruct damaged tissue, prioritizing our body's natural healing process. Thus, the use of bioactive materials such as glass has been studied support repair and restoration hard soft tissue. in this work Bioglass 45S5 was developed, adding 1 2%mol SrO or MgO physical biological properties were evaluated. addition at concentrations promoted slight increase non-bridging oxygens number, observed through temperature shift phase transitions...
Polymeric membranes are widely used in guided bone regeneration (GBR), particularly dentistry. In addition, bioactive glasses can be added to the polymers order develop a matrix that is osteoconductive and osteoinductive, increasing cell adhesion proliferation. The allow insertion into its network of therapeutic ions add specific biological properties. addition zinc promote antibacterial activity induce differentiation proliferation cells. this study, containing (0.25, 0.5, 1 2 mol%) were...
Dental implants have emerged as one of the most consistent and predictable treatments in oral surgery field. However, placement implant is sometimes associated with bacterial infection leading to its loss. In this work, we intend solve problem through development a biomaterial for coatings based on 45S5 Bioglass® modified different amounts niobium pentoxide (Nb2O5). The structural feature glasses, assessed by XRD FTIR, did not change spite Nb2O5 incorporation. Raman spectra reveal...
Conventional bone cancer treatment often results in unwanted side effects, critical-sized defects, and inefficient cancer-cell targeting. Therefore, new approaches are necessary to better address patient's recovery. One solution may reside the combination of regeneration scaffolds with magnetic hyperthermia. By incorporating pristine superparamagnetic iron oxide nanoparticles (pSPIONs) into additively manufactured we created structures for hyperthermia regeneration. For this, hydroxyapatite...
We assembled a new electrospinning apparatus and used poly(ethylene oxide) as model polymer to perform systematic study on the influence of solution processing parameters morphology electrospun nanofibers. Solution studied were concentration molecular mass. The solvent used, 60 wt% water, 40 ethanol, was same throughout study. Processing analyzed were: feed rate, needle tip-collector distance electrostatic potential difference between collector. viscosity increased both with Polymer plays...
A novel cellulose-based bio-battery made of electrospun fibers activated by biological fluids has been developed.
In this study, the main aim was to fabricate propolis (Ps)-containing wound dressing patches using 3D printing technology. Different combinations and structures of (Ps)-incorporated sodium alginate (SA) scaffolds were developed. The morphological studies showed that porosity developed optimized when 20% (v/v) Ps added solution. pore sizes decreased by increasing concentration up a certain level due its adhesive properties. mechanical, swelling-degradation (weight loss) behaviors, release...
