Biological Hazards And Physical Hazards - 1051 Words

Heterodynamic Context Exogenous threats can shape stress responses across the lifespan, and influences the rate of aging (ES-2014-aging). Environmental stressors include any factors that cause cell injury, such as heavy metals, radiation, heat exposure, reactive oxygen species, osmotic fluctuation, as well as social and psychological stressors (ES-2014). These trigger the stress response and related behavioral pathways through neural networks and interconnected neurohormonal and immune patterns. The capacity of human beings to learn about, imagine, remember, and anticipate stressful situations and their warning signs can create chronic states of vigilant arousal in the body. Besides, there are multiple individual differences that make some people more vulnerable to stress, where the identical stimuli cause exaggerated stress responses (ES-2014). Gene-environment interactions in PD Because of the low heritability of PD, more studies focusing on environmental exposures about the PD mechanism (AH-2012). Researchers may focus on both chemical hazards and physical hazards (AH-2012). Exposure to environmental factors or mutations in PD-associated genes of patients may cause mitochondrial dysfunction that ultimately results in PD. All of these share common linkages and influence each other greatly. Limiting the early inflammatory response will reduce further both elevated oxidative stress and microglial activation that are key to slowing the death of the neurons in the SNpc.Show MoreRelatedEnvironmental Hazards: Cultural, Biological, Physical and Chemical727 Words   |  3 PagesEnvironmental Hazards: Cultural, Biological, Physical and Chemical An entirely different perspective is brought into focus as we consider some of the environmental hazards that accompany industrial growth and intensive agriculture.

(Prà ¼ss-ÃÅ"stà ¼n, 2006). Environmental health hazards generally fall into one of three categories: physical, chemical, or biological. The impact an environmental hazard may have on the health of an individual can be greatly affected by the person’s genetics, l ife style, and their risk perceptions. The influence of poor environmental quality on health is greaterRead MoreFood Safety: Cube-Sized Foods for Space Flights Essay911 Words   |  4 Pages HACCP is a management system in which food safety is addressed through the analysis and control of biological, chemical, and physical hazards from raw material production, procurement and handling, to manufacturing, distribution and consumption of the finished product (FDA, 2014).
