The age association and alterations in vascular structure and function at both the cellular and molecular levels are increasingly recognized as major risk factors for CV disease. The arterial remodeling during aging that may be enhanced by the CV risk factors are supersensitive to the age-related risk factors. The aging process may well be influenced by a combination of hereditary and environme...

BACKGROUND Dementia risk reduction is a major and growing public health priority. While certain modifiable risk factors for dementia have been identified, there remains a substantial proportion of unexplained risk. There is evidence that environmental risk factors may explain some of this risk. Thus, we present the first comprehensive systematic review of environmental risk factors for dementia...

This study examined the academic resilience of undocumented immigrant Latino students. It was hypothesized that due to their legal and social marginalization, students who experienced high risk accompanied by high levels of both personal and environmental protective factors would have higher academic outcomes than students with lower levels of these protective resources. The results from regres...

The stress is caused by the feeling of annoyance that is conduced by interpretation with individual value. Therefore, the annoyance from environmental noise shows an association with the stress scores measured by psych...
