衰老过程中生物体与环境的关系

Relations between organisms and the environment in the ageing process

Przemyslaw Biecek, Katarzyna Bonkowska, Stanislaw Cebrat

摘要:

我们通过引入波动环境和代表个体生理功能的波动来修改性Penna模型。此外,我们还介绍了与保护儿童免受环境有害影响相对应的母亲护理、与个人免疫力相对应的学习能力以及对环境波动和青春期出现的其他风险因素的适应。上述每个因素主要影响新生儿和年轻个体的生存,而基因组中积累的遗传缺陷增加了个体的噪音,并导致老年个体的死亡率较高。所有这些修改使得能够精确地将模拟人口的年龄结构拟合到人类人口的年龄分布。

英文摘要:

We have modified the sexual Penna model by introducing the fluctuating environment and fluctuations representing physiological functions of individuals. Additionally, we have introduced the mother care corresponding to the protection against the deleterious influence of the environment, the learning capacity of individuals corresponding to their immunity and adaptation to the environment fluctuations and the other risk factors appearing at puberty. Each of the above mentioned elements influences mainly the survival of newborns and young individuals while genetic defects accumulated in the genomes increase the noise of individuals and were responsible for higher mortality of older individuals. All these modifications enable precise fitting the age structure of the simulated populations to the age distributions of human populations.
