Chitosan has been used as a scaffolding material in tissue engineering due to its mechanical properties and biocompatibility. With increased appreciation of the effect of micro- and nanoscale environments on cellular behavior, there is increased emphasis on generating microfabricated chitosan structures. Here we employed a microfluidic coaxial flow-focusing system to generate cell adhesive chit...
RNA-based microbiological analyses, e.g., transcriptome and reverse transcription-quantitative PCR, require a relatively large amount of high quality RNA. RNA-based analyses on microbial communities in deep-sea hydrothermal environments often encounter methodological difficulties with RNA extraction due to the presence of unique minerals in and the low biomass of samples. In the present study, ...
Keeping food quality among consumers is of high importance. In this study in order to maintain and improve the quality of fish meat, effect of pretreatment with polyphosphates have profound effects on the functional properties of the food products. Experiments were carried out to avoid drip during storage of Tilapia (Oreochromis niloticus)fish under modified atmosphere packaging (MAP).The resul...
Sensory attributes of fully aged broiler breast fillets marinated in a 6% NaCl solution containing 2% sodium tripolyphosphate (2P), 2% citric acid (2C), 2% acetic acid (2A), 1% citric acid plus 1% phosphate solution (1C), or 1% acetic acid solution plus 1% phosphate (1A) were studied. A 6% NaCl (6S) solution with no additives was used as control. Oven-cooked samples (177C degrees oven; 75 degre...
Microspheres of Trimetazidine Hydrochloride (TZ) were prepared by coacervation method without the use of chemical cross–linking agents such as glutaraldehyde to avoid the toxic reactions and other undesirable effects of the chemical cross-linking agents. Alternatively, ionotropic gelation was employed by using sodium-tripolyphosphate (Na-TPP) as cross linking agent. Chitosan was used as polymer...
Native sago starch was phosphorylated with 5% sodium tripolyphosphate (STPP) or crosslinked with 4% phosphorous oxychloride (POCl3) at pH 8 to 11. The modified starches were characterized for degree of substitution (DS), pasting properties, crystallinity and molecular structure. The results indicated that DS of phosphorylated sago starch prepared at pH 9 was 0.008, which was the highest value a...
This study attempted to develop chitosan-based nanoparticles with increased stability and antibacterial activity. The chitosan/protamine hybrid nanoparticles were formed based on an ionic gelation method by mixing chitosan with protamine and subsequently cross-linking the mixtures with sodium tripolyphosphate (TPP). The effects of protamine on the chemical structures, physical properties, and a...
Aim: The present study was aimed to evaluate the efficacy of calculus/tartar dissolution based oral rinse as an adjunct to toothbrushing in gingivitis patients for long-term effects on new supragingival calculus formation. Materials and methods: After undergoing a dental prophylaxis, 60 gingivitis subjects with a moderate rate of calculus formation were stratified and randomly assigned to one o...
The laser dye 6-coumarin was selected as model of low water soluble drug to be encapsulated in glycol chitosan nanoparticles intended for transmucosal applications and, at the same time, being a fluorescent probe, it is of aid to elucidate the intracellular fate of the particles. To increase the aqueous solubility of the tracer, the complexation with different cyclodextrins was adopted. The flu...
Stain formation, stain inhibition and stain removal may be monitored in real-time using a novel method employing a quartz crystal resonance sensor (QCR), based upon quartz crystal microbalance (QCM) technologies. Crystalline hydroxyapatite (HA) surfaces were prepared on phosphate-terminated, polymer-modified gold surfaces of quartz crystal transducers. The resulting sensors were placed in a spe...
