A Bit-String Model for Biological Aging
We present a simple model for biological aging. We studied it through computer simulations and we have found this model to reflect some features of real populations. 1 The problem of aging has been studied recently [1] also by computer simulations, useful in understanding how the survival rates for younger and older individuals evolve in time and affect the preservation of the species [2]–[4]. ...
متن کاملThe Penna Model of Biological Aging
This review deals with computer simulation of biological aging, particularly with the Penna model of 1995. They are based on the mutation accumulation theory of half a century ago. The results agree well with demographical reality, and also with the seemingly contradictory influence of predators on the aging of prey.
متن کاملScaling in a continuous time model for biological aging
In this paper we consider a generalization to the asexual version of the Penna model for biological aging, where we take a continuous time limit. The genotype associated to each individual is an interval of real numbers over which Dirac δ–functions are defined, representing genetically programmed diseases to be switched on at defined ages of the individual life. We discuss two different continu...
متن کاملP 36: Protective Effects of Crocin on D-Galactose Induced Aging Model in Human Neuroblastoma Cells
Introduction: D-galactose (D-gal) is well known as an appropriate agent to induced aging effects in the in vivo and in vitro models. In the present study, we selected crocin, the main constituent of Crocus sativus L. (Saffron), against D-gal cytotoxicity in human neuroblastoma SH-SY5Y cells. Materials and Methods: Cells were pretreated with crocin (25-500 µM) for 24 h and then expos...
متن کاملA person-specific, rigorous aging model of the human face
We present a statistically rigorous approach to the aging of digitised images of the human face. Our methodology is based on the calculation of optimised aging trajectories in a model space and aged images can be obtained through a fast, semi-automatic procedure. In addition, person-specific information about the subject at previous ages is included, allowing aging to proceed in the most approp...
