Myocardial infarction (MI), triggered by blockage of a coronary artery, remains the most common cause of death worldwide. After MI, the capability of providing sufficient blood and oxygen significantly decreases in the heart. This event leads to depletion of oxygen from cardiac tissue and consequently leads to massive cardiac cell death due to hypoxemia. Over the past few decades, many studies have been carried out to discover acceptable approaches to treat MI. However, very few have addressed t...

After myocardial infarction caused by a heart attack, endothelial cells need to be preserved in order to regenerate new capillaries. Moreover, sufficient mechanical support is necessary for the infarcted myocardium to pump the blood. Herein, we designed a novel substrate containing polyurethane (PU) nanofibrous layers and recombinant human erythropoietin (rhEPO)-loaded microparticles for both controlled releases of rhEPO and mechanical support of myocardium. In this system, the single-layer (SL)...

Since the emergence of the novel coronavirus, named COVID-19, researchers are looking for a treatment to stop the devastating pandemic. During these efforts, mesenchymal stem cells (MSCs), the potential next generation of therapeutic methods with wide application for diseases, have successfully controlled cytokine storm following the virus infection. However, the use of MSCs has been limited due to the ethical issues, immunogenicity, and genetic modifications. Therefore, exosomes were introduced...

Magnesium alloys have received great attention for the medical applications due to their desired properties.But the main problem of magnesium alloys is the high rate of degradation which provides not enough time for healing.Therefore, in this study, it was tried to control the corrosion rate of Mg-Zn-Ca alloy by applying a nanofiber of polycaprolactone polymer coating and investigate the behaviors such as biocompatibility and rate of degradation. For this purpose, the polymer nanofibers were pre...

Abstract A novel nanofibrous coating containing chitosan and mineralized bone allograft (MBA) nanoparticles was fabricated on AZ31 magnesium alloy via electrospinning in order to enhance corrosion and biocompatibility behavior in a physiological environment. A number of specimens were initially anodized to assess its effect on the improvement of the adhesion between the electrospun nanofibrous coating and the substrate. The coated materials were characterized by using SEM, EDS, FT-IR, and TG. We...

Chitosan based nanofibers containing carbon nanotubes were applied on AZ31 magnesium alloy via electrospinning. The magnesium substrate was initially anodized in a NaOH solution in order to improve the adhesion between the coating and substrate. Electrospinning parameters were optimized and homogenous nanofibers composite coatings were produced. Addition of carbon nanotubes reduced the size of the chitosan nanofibers. Also the size distribution of the fibers became more uniform. The chemical str...

Abstract SiBNC nanofibers were synthesized through the polymeric route by a one-pot synthesis approach. DMTA (dichloroboryl methyl trichlorosilyl amine) polymer was selected as pre-ceramic for SiBNC, which was shaped into nanofibers by electrospinning. Then, the nanofibers were cured in an inert atmosphere in order to obtain the final ceramic. By changing the curing atmosphere, the compound of final ceramic has been manipulated. In addition, the ceramic yield of DMTA as a preceramic was increase...

As a novel cardiac myosin activator, Omecamtive Mecarbil (OM) has shown promising results in the management of systolic heart failure in clinical examinations. However, the need for repeated administration along with dose-dependent side effects made its use elusive as a standard treatment for heart failure (HF). We hypothesized that improved cardiac function in systolic HF models would be achieved in lower doses by targeted delivery of OM to the heart. To test this hypothesis, a nanocomposite sy...
