Poly(ethlene terephthalate) (PET) used in artificial heart valve sewing rings were treated by argon plasma discharge and grafted by different molecular water-soluble polymer—polyethylene glycols (PEG). The surface properties of the plasma treated and grafted films were determined by contact angle measurement, X-ray photoelectron spectroscopy (XPS), and attenuated total reflection Fourier transf...
Ti-6Al-4V alloy attracting attention as a biomaterial features excellent mechanical properties and corrosion resistance, and super plasticity, so enables the forming of denture bases of complicated shapes. However, this alloy contains aluminum and vanadium liable to do serious harm to human bodies [1,2], so actual use will require prevention of direct contact with biological tissues. In our pre...
مدیریت زنجیره تامین خون یکی از اجزای اصلی سیستم سلامت هر کشور محسوب می گردد. این زنجیره از دو جزء جمع آوری خون اهدا کنندگان و عرضه فرآورده های خون تشکیل شده است. این مقاله با تمرکز روی موضوع عرضه فرآورده های مختلف خون، سعی در ارائه یک مدل ریاضی جهت کاهش هزینه های اتلاف و کمبود موجودی فرآورده های خونی بیمارستان ها دارد. در این مدل ضمن برآورده ساختن نیازهای بیمارستانها در گروههای مختلف خون هزینه ...
Objective(s): Titanium oxides are known to be appropriate hemocompatible materials which are suggested as coatings for blood-contacting devices. Little is known about the influence of nanometric crystal structure, layer thickness, and semiconducting characteristics of TiO2 on blood hemostasis. Materials and Methods: Having used sol-gel dip coating method in this study, TiO2 thin films were d...
A variety of strategies has been developed to assure safety of hemotherapy. Such strategies aim in particular at avoiding transfusion-transmitted infections. Safety of hemotherapy requires – in addition to safety of transfusion from infections – tolerance of the recipient towards the blood component to be transfused and tolerance of the blood component to be transfused towards the recipient, i....
