Objective(s): One of the main constraints of collagen hydrogel scaffolds for using in tissue engineering is mechanical weakness. Plastic compression (PC) is a physical method to overcome the mechanical limitation of collagen hydrogel. Materials and Methods: In this study, the effects of pH on mechanical and biological properties of PC hydrogels were investigated. Collagen hydrogels were fabrica...

Background: Marine seaweeds synthesize different types of compounds with various biological activities, including anti-tuberculosis and anticancer effects. Objective: The aim of this study was to evaluate anti tuberculosis of Padina australis and cytotoxicity of different fractions of this seaweed. Methods: Padina australis was collected from coasts of Persian Gulf, identified and e...

Prevention of malignant disease such as cancer is obviously much more important than therapy, so primary prevention tactics should be invoked with the greatest possible effort. Because delaying a disease such as cancer is somehow equivalent to cure and it is now generally accepted that cancer can be managed through chemopreventive interventions. Since a considerable number of known cancer chemo...

background: study in design to incorporate accelerated proliferation correction factors into linearquadratic and multiple-component models. materials and methods: accelerated proliferation rate correction factor has been incorporated into the linearquadratic and the multiple component models by applying accelerated exponential cell growth to explain the tumor cell kinetics and estimates proper ...
