the overall goal of this study was to identify the appropriate biomaterials able to facilitate the regeneration in rat's injured adult spinal cord. acute damage to axons is manifested as a breach in their membranes, ionexchange distortion across the compromised region, local depolarization and even conduction block. it would be of particular importance to interrupt the progress of events h...

Utilization of membrane humidifiers is one of the methods commonly used to humidify reactant gases in polymer electrolyte membrane fuel cells (PEMFC). In this study, polymeric porous membranes with different compositions were prepared to be used in a membrane humidifier module and were employed in a humidification test. Three different neural network models were developed to investigate several...

background: amniotic membrane derived stem cells (amscs) have considerable advantages to use in regenerative medicine and their anti- inflammatory effects, growth factor secretion and differentiation potential make them suitable candidates for stem cell therapy of nervous system. the developing and neonatal brain contains a spectrum of growth factors to direct development of endogenous and dono...

Embryogenesis, regeneration and cell differentiation in microbiological entities are influenced by mechanical forces. Therefore, development of mechanical properties of these materials is important. Neural network technique is a useful method which can be used to obtain cell deformation by the means of force-geometric deformation data or vice versa. Prior to insertion in the needle injection pr...

the effect and arrangement of cytoskeleton (microtubules, microfilaments and neurofilaments) in neurulation of chick embryo examined by immunoperoxidase method from stage 6 to stage 12. the results were as follows: 1) microtubules aggregated in the perinuclear region from which they radiated to take longitudinal course beneath the membrane. 2) microfilaments were aggregated in the apical ends (...

Objective: Pomegranate juice is a fruit native to Iran because of attractive color, smell and value of mineral water is popular fruits in the world. Pomegranate juice has more nutritional value is due to a combination of anthocyanins that reduce the risk of diseases such as cancer. Processes Feta membrane such as microfiltration 1 and 2 are used to clarify beer industry. Methods: The advantage ...

zinc is a substance that regulates neural excitability by binding whit sodium channel and potassium channel. the efficiency of free zinc ion, make down the neural survival rate, reduced the peak amplitude of na+ and make depolarization na channel, increased the peak amplitude of transition outward k+ currents and delayed rectifier. also it is an effective blocker of one subtype of tetrodoxine (...

artificial neural networks (anns) are computer techniques that attempt to simulate the functionality and decision-making processes of the human brain. in the past few decades, artificial neural networks (anns) have been extensively used in a wide range of engineering applications. there are only a few applications in liquid membrane process. the objective of this research was to develop artific...
