Abstract:

Background and purpose: Some skin injuries are caused by occupational skin exposures that are resulted from production of reactive oxygen species and oxidative stress (ROS). Thus, protecting the skin is a key issue. Recently, several surveys have introduced novel alternatives such as nanofibers for skin protection. In this research, Poly (ε-caprolactone) (PCL)/gelatin (Gt)/ Vitamin E (VE) was investigated as a nanofiber antioxidant protective layer in occupational skin exposures. Materials and methods: Vitamin E was combined with PCL/Gt nanofiber mats by electrospinning method. The diameter of nanofibers and chemical characteristics were determined using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). Adhesion characteristics and proliferation of human dermal fibroblast cells (HDFC) on nanofibers were analyzed by Methylthiazol Tetrazolium (MTT) assay. Finally, we studied the application of PCL/Gt/VE nanofibers against oxidation stress induced by tert-butyl hydroperoxide (t-BHP). Results: With increase in Vitamin E levels, the PCL/Gt/VE nanofibers were found to be thiner. The culture of HDF cells on nanofibers showed that adding Vitamin E to PCL/Gt mats caused increased attachment and proliferation of the cells. PCL/Gt/VE nanofibers significantly assisted human skin cells against ROS (P< 0.001). Conclusion: According to current study, PCL/Gt/VE nanofibers could be an appropriate candidate for protecting skin against ROS as a novel method to maintain workers’ health.

Modeling Electrospinning of Nanofibers

A fast discrete model for the simulations of thin charged jets produced during the electrospinning process is derived, based on an efficient implementation of the boundary element method for the computation of electrostatic interactions of the jet with itself and with the electrodes. Short-range electrostatic forces are evaluated with slender-body analytical approximations, whereas a hierarchic...

Upward Needleless Electrospinning of Nanofibers

Polyacrylonitrile (PAN) nanofibers were prepared by a needleless electrospinning method using three rotating fiber generators, cylinder, disc and coil. The effects of the spinneret shape on the electrospinning process and resultant fiber morphology were examined. The disc spinneret needed the lowest voltage to initiate fiber formation, followed by the coil and cylinder. Compared to cylinder, th...

Analysis of Oxidative Stress in Chronic Exposure to Petroleum Hydrocarbons in Karnataka, India

Background:Several studies have reported the toxicological implications of inhalation of petroleum hydrocarbon fumes in animal models. But, there is certainly little or no documentation of the exposure to petroleum hydrocarbon fuel on oxidative stress levels in humans, unlike the pulmonary physiology. The present study was carried out to evaluate the effects of constituents of the hydrocarbon f...
