Abstract

ABSTRACT

         Background and Objective: Hospital clothing and textiles have a great role in providing medical services to patients. Hospital services would not be possible without using these textiles. The aim of this study was to prepare non-woven polyester for use in medical textiles.

         Methods: In this study, most important expected properties of hospital clothing were created on polyester fabrics via various stages of finishing using chemicals such as calcium chloride, sodium alginate, chitosan and nanoparticles of silver nitrate and aluminum oxide. Antibacterial (activity against Staphylococcus aureus), deodorizing and wicking properties of samples were evaluated using nano-biomaterials via standard tests.

          Results: The water absorption rate of nonwoven samples that were finished with chitosan significantly improved. The results also showed favorable level of antimicrobial activity caused by silver nitrate and chitosan. In addition, deodorizing activity was observed in all samples. However, silver nitrate-finished samples had higher deodorizing activity. The capillary action of all samples reduced after completion of all finishing procedures.

          Conclusion: The results show that the use of chitosan and alginate along with nanoparticles of silver nitrate and aluminum oxide can be effective in achieving the desired properties of medical textiles.

        Keywords: Medical textiles, antibacterial substances, chitosan, silver nitrate.

Abstract
Introduction: DNA Glycation damages DNA by inducing breaks of strands, mutations, and finally changes in gene expression, which is assumed as a main factor in pathogenesis of diabetes and its complications. Therefore, antiglycation agents have been focused recently for preventing and alleviating diabetes complications. According to the reported antidiabetic effects of Tamarix aphylla (T. aphylla) leaves extract, this study was aimed to determine the effect of T. aphylla on glucose-mediated DNA glycation for the first time.
Methods: DNA incubated with glucose for 4 weeks and the inhibitory or fascilitatory effects of T. aphylla on DNA structural changes were studied by various techniques. These techniques were included UV–Vis, fluorescence spectroscopy, circular dichroism (CD) and agarose gel electrophoresis.
Results: The findings of UV–Vis and fluorescence spectroscopy showed that T. aphylla decreased the DNA-AGE (advanced glycation end products) formation. Based on the CD and agarose gel electrophoresis results, the structural changes of glycated DNA was decreased in the presence of T. aphylla.
Conclusion: Thus T. aphylla has beneficial effects against DNA glycation and could be a promising agent for ameliorate the adverse effects of glycation in the presence of glucose and conditions of raised blood glucose after confirming in further studies.
