Objective: In this study we would like to report the synthesis of pure and group I element doping of ZnO nanoparticles (ZnO-NPs) prepared using gelatin. The use of natural polymers for the preparation of the pure and doped nanoparticles can result in achieving low cost and eco-friendly advantages.Materials and Method: Pure and doped ZnO-NPs were obtained at 500 °C and The cytotoxicity of nanopa...
Pharmaceutical suspension containing oral dosage forms delivering both immediate-release and sustained-release amoxicillin was developed as a new dosage form to eradicate Helicobacter pylori. Amoxicillin-loaded gelatin nanoparticles are able to bind with the mucosal membrane after delivery to the stomach and could escalate the effectiveness of a drug, providing dual release. The objective of th...
BACKGROUND In order to obtain biomaterials with controllable physicochemical properties, hybrid biomaterials composed of biocompatible biopolymers and ceramic nanoparticles have attracted interests. In this study, we prepared biopolymer/ceramic hybrids consisting of various natural biopolymers and layered double hydroxide (LDH) ceramic nanoparticles via an electrophoretic method. We studied the...
Mesenchymal stem cell- (MSC-) based therapy is regarded as a potential tissue engineering strategy to achieve nucleus pulposus (NP) regeneration for the treatment of intervertebral disc degeneration (IDD). However, it is still a challenge to induce MSC differentiation in NP-like cells when MSCs are implanted into the NP. The purpose of this study was to construct poly(D,L-lactide-co-glycolide) ...
In this study, for the first time, lanternfish gelatin (Benthosema pterotum Alcock, 1890) was extracted and the composition (moisture, ash, protein), gel strength, gelling and melting temperature of extracted gelatin was investigated and compared with those of the commercial bovine gelatin purchased from market. The two gelatin samples were also compared in terms of color properties. Moisture a...
background: development of biodegradable and biocompatible films based on protein polymer with strong antioxidant and antibacterial activities has gradually obtained extensive concern in the world. in this study, the improvement of gelatin film properties incorporated with ferula assa-foetida essential oil (fao) as a potential antioxidant/antibacterial wound dressing film was investigated. mate...
The aim of present study was to formulate and evaluate nanoparticles of acyclovir by using different hydrophilic polymers. Acyclovir was selected as a suitable drug for gastroretentive nanoparticles due to its short half life, low bioavailability, high frequency of administration, and narrow absorption window in stomach and upper part of GIT. The nano-precipitation method was used to prepare na...
