Abstract
The development of an effective hemostatic agents is of vital importance for saving wounded individuals from uncontrolled hemorrhage, which is the main reason for preventable death after accidental injury. However, current high-performance hemostatic agents suffer from a cumbersome preparation procedures and poor biocompatibility. Here, we engineered a cellulosic-derived aerogel material by simply controlling the drying process of cellulose regeneration for fast hemostasis. Four different freeze-drying pretreatments were investigated. As compared with the other three, the cellulosic aerogel material prepared without freezing pretreatment exhibited the lowest crystallinity (21.3%) and the highest body fluid absorption capacity (20.3 times that of its own weight) due to its super hierarchical porous structure, which led to an excellent hemostatic performance in vitro blood coagulation (≈100 s). Moreover, the addition of gelatin and diatomite in the material could tune the functional groups and electrostatic properties of the aerogel and further enhance its hemostatic performance. Various characterizations, including X-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR), X-ray nanocomputed tomography (CT), scanning electron microscopy (SEM), and zeta potential analysis, were carried out to probe the structure-function relationship of the prepared material, and its mechanism of fast hemostasis was thereafter revealed. The results indicate that the developed aerogel is a cost-effective and feasibly scalable hemostatic material suitable for practical use in industry.

Abstract
While biomaterials have become indispensable for a wide range of tissue repair strategies, second removal procedures oftentimes needed in the case of non-bio-based and non-bioresorbable scaffolds are associated with significant drawbacks not only for the patient, including the risk of infection, impaired healing, or tissue damage, but also for the healthcare system in terms of cost and resources. New biopolymers are increasingly being investigated in the field of tissue regeneration, but their widespread use is still hampered by limitations regarding mechanical, biological, and functional performance when compared to traditional materials. Therefore, a common strategy to tune and broaden the final properties of biopolymers is through the effect of different reinforcing agents. This research work focused on the fabrication and characterization of a bio-based and bioresorbable composite material obtained by compounding a poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) matrix with acetylated cellulose nanocrystals (CNCs). The developed biocomposite was further processed to obtain three-dimensional scaffolds by additive manufacturing (AM). The 3D printability of the PHBH-CNC biocomposites was demonstrated by realizing different scaffold geometries, and the results of in vitro cell viability studies provided a clear indication of the cytocompatibility of the biocomposites. Moreover, the CNC content proved to be an important parameter in tuning the different functional properties of the scaffolds. It was demonstrated that the water affinity, surface roughness, and in vitro degradability rate of biocomposites increase with increasing CNC content. Therefore, this tailoring effect of CNC can expand the potential field of use of the PHBH biopolymer, making it an attractive candidate for a variety of tissue engineering applications.

Abstract
Owing to the noticeable increase in the number of patients with impaired wound healing capabilities, developing bioactive wound dressings with supportive physicomechanical and biological properties for clinical wound management has attracted much more attention nowadays. In this regard, engineered dressings with angiogenesis potential are vital for accelerated tissue regeneration. In the current study, nanoniosomal deferoxamine (DFO)-loaded transparent films of egg white-poly(vinyl alcohol) (PVA/EW/ND) were successfully fabricated at three different PVA/EW ratios (1:0, 1:1, and 1:1.5 wt/wt %) through the thin film hydration and solvent casting methods. The developed films' characterizations were carried out using scanning electron microscopy, Fourier transform infrared spectroscopy analysis, uniaxial tensile strength, water uptake, water vapor transmission rate, in vitro degradation, and drug release. The results demonstrated that the various weight ratios of PVA/EW have a significant effect on the microscopic morphology, equilibrium swelling, degradation, and mechanical properties of the films. The drug release profile exhibited a sustained release of DFO with controlled burst-lag phases resembling the Korsmeyer-Peppas pattern. The cytotoxicity and adhesion analysis using human dermal fibroblasts displays the biocompatibility of the developed PVA/EW/ND films and the formation of cellular colonies on the surface. The in vitro angiogenic capability of the developed films evaluated by the scratch wound assay and microbead-assisted tube formation study showed a significant increase in the rate of migration of human umbilical vein endothelial cells and in the number of tube-like structures. Therefore, the achieved results suggest that the presented PVA/EW/ND film has promising potential for effective wound healing applications.

Abstract
The main objective of this study was to assess the therapeutic activity of gum odina and gelatin based biomimetic scaffold which was previously established as an excellent wound dressing material. In the accelerated stability study, the changes in physicochemical properties were found to be negligible. The cytotoxicity studies were carried out in-vitro and the results showed that upto 90% of the cells remained viable in presence of the scaffold, confirming its biocompatibility. Moreover, results depicted the superior ability of the scaffold to promote cutaneous healing by increasing the rate of wound contraction (about 98%), granulation formation, collagen deposition and formation of an intact epidermis within 18 days. A satisfactory amount of hydroxyproline (240.2 ± 6.67 μg/100 mg tissue) in scaffold treated groups at 21 days ensured the significant deposition of collagen to re-epithelialization. Further it can be hypothesized that the controlled levels of antioxidant enzymes (SOD, CAT) to diminish the oxidative stress in the wounded sites were due to the innate antioxidant properties of both blank and drug loaded scaffold. These results strongly indicated that the prepared scaffolds have strong potential for biomedical applications and it may serve as promising candidate for the next generation of wound treatment systems.

Abstract
Impaired skin wound healing due to severe injury often leads to dysfunctional scar tissue formation as a result of excessive and persistent myofibroblast activation, characterised by the increased expression of α-smooth muscle actin (αSMA) and extracellular matrix (ECM) proteins. Yet, despite extensive research on impaired wound healing and the advancement in tissue-engineered skin substitutes, scar formation remains a significant clinical challenge. This study aimed to first investigate the effect of methacrylate gelatin (GelMA) biomaterial stiffness on human dermal fibroblast behaviour in order to then design a range of 3D-printed GelMA scaffolds with tuneable structural and mechanical properties and understand whether the introduction of pores and porosity would support fibroblast activity, while inhibiting myofibroblast-related gene and protein expression. Results demonstrated that increasing GelMA stiffness promotes myofibroblast activation through increased fibrosis-related gene and protein expression. However, the introduction of a porous architecture by 3D printing facilitated healthy fibroblast activity, while inhibiting myofibroblast activation. A significant reduction was observed in the gene and protein production of αSMA and the expression of ECM-related proteins, including fibronectin I and collagen III, across the range of porous 3D-printed GelMA scaffolds. These results show that the 3D-printed GelMA scaffolds have the potential to improve dermal skin healing, whilst inhibiting fibrosis and scar formation, therefore potentially offering a new treatment for skin repair.

Abstract
2,2'-Dimorpholinodiethyl ether (DMDEE) is a specialty amine catalyst used in the production of flexible foams, adhesives, and coatings. The potential for occupational exposure to DMDEE is high, but toxicity data are very limited. The objective of this work was to develop a method to quantitate DMDEE in biological matrices to assess gestational and lactational transfer of DMDEE in rats following exposure of dams. The method used protein precipitation, followed by removal of phospholipids and analysis of supernatant by ultra-performance liquid chromatography-tandem mass spectrometry. Rat fetuses were homogenized in water prior to protein precipitation and delipidation procedures. The method was evaluated in male Sprague Dawley (SD) rat plasma over the concentration range 5 to 1000 ng/mL. The method was linear (r ≥ 0.99), accurate (mean relative error (RE) ≤ ± 11.9%) and precise (relative standard deviation (RSD) ≤ 2.7%). The mean absolute recovery was 106%. The limit of detection (LOD) was 0.262 ng/mL. Standards as high as ~ 100,000 ng/mL could be successfully diluted into the calibration range (mean %RE = -14.9; %RSD = 0.5). The method was evaluated in SD rat dam plasma, post-natal day (PND) 4 pup plasma, gestational day (GD) 18 amniotic fluid and fetal homogenate (mean %RE ≤ ± 11.9; %RSD ≤ 2.3). Concentrations of DMDEE in rat dam plasma, amniotic fluid, and fetal homogenate stored for at least 29 days and in pup plasma for at least 18 days at -80°C were within 87.7 to 99.5% of Day 0 concentrations, demonstrating that DMDEE is stable in these matrices. The method was used to quantitate DMDEE in rat plasma, amniotic fluid, and fetus samples from a dose range finding toxicology study in which dams were dosed via gavage with DMDEE from GD 6 at doses of 0 (control), 62.5 and 250 mg/kg/day. DMDEE concentration increased with the dose in all matrices examined. The concentration in GD 18 fetuses was almost two-fold higher than GD 18 dams demonstrating gestational transfer of DMDEE. However, the concentration in PND 4 pup plasma was more than an order of magnitude lower than corresponding dam plasma suggesting less potential for transfer of DMDEE from dams to pups via lactation. There was no significant difference in concentration for male and female pup plasma.

Abstract
OBJECTIVE Biodegradable polymers can replace damaged tissue components using tissue engineering techniques. The objective of this study is to determine an optimum environment for polymer scaffolds to improve the proliferation of fibroblast cells capable of wound repair. METHOD In this study, the addition of polysaccharides, such as chitosan (CH) or hyaluronic acid (HA), to a polyurethane (PU) polymer was evaluated using different methods to determine if they affect scaffold morphology and cell activity of fibroblasts prepared from human foreskin tissues. Mechanical properties, such as tensile strength, contact angle and swelling test, were used to check the physical and mechanical properties of the scaffold. Fibroblast growth was also measured at 24, 48 and 72 hours. RESULTS Scanning electron microscopy (SEM) determined that a 3:1 ratio of PU/CH scaffold, developed by electrospinning, allowed the formation of a uniform structure in scaffold fibres. Physical mechanical tests showed that PU electrospun scaffolds were not modified by the addition of CH. The mean stretch and mean water absorption increased significantly using the PU/CH scaffold, compared with the PU scaffold. However, the mean tensile strength and the mean contact angle, used to study space and porosity, did not differ between scaffolds. Fourier transform infrared spectroscopy confirmed the functional groups (-OH, -NH and -C=O) in the PU/CH scaffold, compared with PU or CH chemical structures alone. HA was then added to CH and PU/CH scaffolds to evaluate the growth of fibroblast cells. Results showed that cell viability and the number of cells, using MTT and trypan blue exclusion assay, respectively, increased significantly at 24, 48 and 72 hours of culture in PU/CH/HA scaffold compared to HA, CH/HA, and PU/HA. Moreover, PU/HA at 48 and 72 hours also increased cell viability and cell numbers compared to HA and CH/HA scaffolds. However, scaffolds at 72 hours had limited space for cell growth. Moreover, SEM data demonstrated that fibroblasts were able to proliferate, penetrate, migrate and survive on PU/HA and PU/CH/HA three-dimensional scaffolds, especially during the first 48 hours. Furthermore, 4',6-diamidino-2-phenylindole (DAPI) staining confirmed that fibroblasts could penetrate PU scaffolds and showed higher cell viability and lower cellular damage in PU/CH/HA, compared to CH/HA and PU/HA scaffolds. Finally, flow cytometry using CD90 and CD105 surface markers revealed that >90% of cells isolated from the human dermis were fibroblasts. CONCLUSION In summary, PU/HA and PU/CH/HA scaffolds were found to be biocompatible and provided a suitable environment for the growth and proliferation of fibroblasts, which filled and covered all pores between the fibres. The new scaffold used in this study, made of synthetic and natural polymers, is a good candidate for applications in tissue engineering. It is therefore recommended to use PU in grafts or in wound dressing.

Abstract
Being biodegradable and biocompatible are crucial characteristics for biomaterial used for medical and biomedical applications. Vegetable oil-based polyols are known to contribute both the biodegradability and biocompatibility of polyurethanes; however, petrochemical-based polyols were often incorporated to improve the thermal and mechanical properties of polyurethane. In this work, palm oil-based polyester polyol (PPP) derived from epoxidized palm olein and glutaric acid was reacted with isophorone diisocyanate to produce an aliphatic polyurethane, without the incorporation of any commercial petrochemical-based polyol. The effects of water content and isocyanate index were investigated. The polyurethanes produced consisted of > 90% porosity with interconnected micropores and macropores (37-1700 µm) and PU 1.0 possessed tensile strength and compression stress of 111 kPa and 64 kPa. The polyurethanes with comparable thermal stability, yet susceptible to enzymatic degradation with 7-59% of mass loss after 4 weeks of treatment. The polyurethanes demonstrated superior water uptake (up to 450%) and did not induce significant changes in pH of the medium. The chemical changes of the polyurethanes after enzymatic degradation were evaluated by FTIR and TGA analyses. The polyurethanes showed cell viability of 53.43% and 80.37% after 1 and 10 day(s) of cytotoxicity test; and cell adhesion and proliferation in cell adhesion test. The polyurethanes produced demonstrated its potential as biomaterial for soft tissue engineering applications.

Abstract
Remarkable properties of hydrogels are compromised by failure to recover from damage, bringing their intended functions to an end. To address this, hydrogels can be functionalized with self-healing property to enable them to restore themselves after damage, thus, extending their lifetime. Herein, hydrogels were prepared by cross-linking acrylamide-modified β-chitin (Am-β-Chn) with alginate dialdehyde (ADA) to form Schiff base, showing IR characteristic peak at 1650 cm-1, attributed to the stretching vibration of CN. The dynamic Schiff base and H-bond rendered the double crosslinked hydrogels self-healing as demonstrated by continuous step strain rheology. Characterization of the hydrogels revealed excellent biocompatibility, biodegradability, injectability and self-healing properties. Furthermore, the wound healing property of the hydrogels was investigated in vivo using zebrafish as a model system. Indirect application of Am-β-Chn/ADA hydrogel remarkably led to ~87% wound healing as compared to control which gave ~50%, suggesting that hydrogels are effective in accelerating wound healing. However, a clear understanding of the exact mechanism of its wound healing property remains to be investigated. To the best of our knowledge, this is the first innovation of developing novel double crosslinked Am-β-Chn/ADA hydrogels with both self-healing and accelerated wound healing properties, directly from marine-food wastes.

MATERIALS SCIENCE & ENGINEERING. C, MATERIALS FOR BIOLOGICAL APPLICATIONS 2017; 78:163-174.

Abstract
Degradable foams which can be inserted endoscopically as liquid or pasty mixtures into soft tissue defects possess a promising potential for the surgical treatment of such defects. The defects can be sealed under in situ foaming and simultaneous material expansion. We developed an in situ foamable (l-lactide-co-ε-caprolactone)-based, star-shaped prepolymer by ring opening polymerization of l-lactide and ε-caprolactone in the presence of meso-erythritol as starter. By conversion of the terminal hydroxyl groups of the formed oligoester with lysine diisocyanate ethyl ester (LDI) an isocyanate-endcapped, reactive prepolymer has been received. Foaming can be initiated by addition of 1,4-diazabicyclo[2,2,2]octane (DABCO), water, LDI and DMSO. By varying the composition of these additives, the foaming and curing time could be varied within a clinically acceptable range. A porosity of approximately 90%, and an average tensile strength of 0.3MPa with elongations of 90% were determined for the foams. In vitro cytotoxicity on cured foams was assayed on 3T3 fibroblasts and demonstrated an excellent cytocompatibility. This was also confirmed in an in vivo study using an established rat model, where prefabricated foams and in situ hardening material were inserted into subdermal skin incisions in parallel. The feature of chronic inflammation was only weakly developed in both groups and slightly more pronounced and persisted for longer time in the group of in situ foamed material. In both groups the foreign materials were vascularized, degraded and substituted by connective tissue. The results encourage to proceed with trials where the materials are used to fill more heavily loaded defects.
