Bone tissue is able to heal itself but in cases of serious damage and auxiliary treatment methods are necessary. Nevertheless, they have their own restrictions and downsides. Tissue engineering is working towards overcoming these challenges using 3D printing and freeze-drying technique. This research project aims to develop and study the properties of a freeze-dried antibacterial tissue based on alginate, hyaluronic acid and titanium dioxide nanoparticles using freeze drying technique. The mechanical evaluations showed that the addition of titanium dioxide improved tensile strength, hardness and wettability of the antibacterial nanocomposite scaffold. The biological assessments of the sample were evaluated in the simulated body fluid to stimulate the hard tissue reaction with biological environment. The samples were characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis. The obtained results indicated that addition of titanium oxide nanoparticle improved the hyaluronic acid polymer for bone filler using for orthopedic applications. The XRD analysis did not detect the formation of any new unwanted chemicals in the composite samples. The microscopic assessments confirmed the formation of nanocomposite scaffold containing titanium dioxide nanoparticles, with a porosity percentage between 77% and 82%. The phase analysis confirmed the triploid amorphous structure showing a significant resemblance to natural human bone tissue, thus supporting the idea of using this biomaterial as a multilayer bone filler.}, keywords = {Biomaterials,Scaffolds,Bone substitute,Orthopedics,cartilage}, url = {https://www.nanomedicine-rj.com/article_47983.html}, eprint = {https://www.nanomedicine-rj.com/article_47983_81547edc5fb6161abcbde82934dd67bc.pdf} } @article { author = {Kapare, Harshad and Metkar, Sarika and Shirolkar, Satish}, title = {Design and development of plumbagin loaded poly (ε -caprolactone) nanoparticles for improved cytotoxicity}, journal = {Nanomedicine Research Journal}, volume = {5}, number = {4}, pages = {316-323}, year = {2020}, publisher = {Tehran University of Medical Sciences}, issn = {2476-3489}, eissn = {2476-7123}, doi = {10.22034/nmrj.2020.04.002}, abstract = {Poly (ε -caprolactone) nanoparticles were investigated as an injectable nanocarrier for the delivery of natural anticancer naphthoquinones plumbagin with the primary aim of improvement in its solubility, drug release profile and in vitro cytotoxicity.

Despite the toxicity at high concentrations, these particles are non-toxic and useful at low concentrations. Thus, we investigated the effectiveness of nontoxic Ag-NPs to interfere with the aversive effect of naloxone (NLX) and low expression of c-Fos during testing of morphine-induced conditioned place preference (CPP) in rats. Methods: The Wistar rats (weighing 300-350 g) were cannulated bilaterally by stereotaxic apparatus for the CeA (AP= –2.12 mm; L= ±4.1 mm; V= 7.8 mm). CPP was conducted via a three-phase unbiased procedure. Morphine (0.5-7.5 mg/kg) was injected subcutaneously (sc) during the conditioning phase. NLX (0.4 µg/rat) was given, intra-CeA, 10 min before the test. Ag-NPs (0.01 µg/rat) was administered prior to the antagonist. The control group received saline (1 µL/rat, intra-CeA). c-Fos expression was quantified immunohistochemically in rats subsequent the injections: Results: The CeA and hippocampal cornu ammonis 1 (CA1) of rats that treated by NLX showed low c-Fos protein levels during testing, whereas levels of protein were high in the brains of morphine conditioned rats. Interestingly, both areas (CeA and CA1) showed similar increases in protein levels when the injection of NLX was combined with the Ag-NPs. However, these regions were not significantly different in the single Ag-NPs receiving and control groups. Conclusions: This indicates that the two regions interact with each other when NLX is injected and that in presence of Ag-NPs the protein levels are elevated in the regions.}, keywords = {Central amygdala,c-Fos,Morphine,naloxone,Silver nanoparticles}, url = {https://www.nanomedicine-rj.com/article_47986.html}, eprint = {https://www.nanomedicine-rj.com/article_47986_c8a94c7a6c4282ff7e166eb7424651d8.pdf} } @article { author = {Sharifi, Fatemeh and Sharififar, Fariba and Soltanian, Sara and Doostmohammadi, Mohsen and Mohamadi, Neda}, title = {Synthesis of silver nanoparticles using Salvia officinalis extract: Structural characterization, cytotoxicity, antileishmanial and antimicrobial activity}, journal = {Nanomedicine Research Journal}, volume = {5}, number = {4}, pages = {339-346}, year = {2020}, publisher = {Tehran University of Medical Sciences}, issn = {2476-3489}, eissn = {2476-7123}, doi = {10.22034/nmrj.2020.04.005}, abstract = {Objective: This study aimed to investigate the cytotoxicity, antileishmanial and antibacterial potential of silver nanoparticles (AgNPs) synthesized by (Salvia officinalis L.

The aim of the present study is to prepare eucalyptus oil based nanoemulsions, its characterization and in vitro evaluation of its antimicrobial activity. Methods: O/W nanoemulsions were prepared by using eucalyptus essential oil in the presence of surfactants like tween 20, tween 80 and sodium dodecyl sulphate (SDS). Physiochemical parameters like pH, conductivity, optical density and antibacterial activity were studied. Stability of nanoemulsions was studied for 120 days. Results: Nanoemulsions prepared with tween 20/80 and SDS were smaller in size than those prepared with tween 20/80. Formulated nanoemulsions were stable even after 120 days as no significant change in pH, conductivity, size of droplet was observed. Substantial in vitro antibacterial activity against Bacillus subtilis was observed with nanoemulsions prepared with tween 20 only.
