This study aimed to investigate the independent and interactive influences of apolipoprotein E (APOE) ε4 and beta-amyloid (Aβ) on multiple cognitive domains in a large group of cognitively normal (CN) individuals and patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD). Participants were included if clinical and cognitive assessments, amyloid imaging, and APOE genotype wer...

In a continuous opinion dynamics model using a bounded confidence assumption, individuals can only influence each other’s opinions when those opinions are sufficiently close. However, we often observe real-world cases in which opinions are very different, yet individuals feel compelled to change their ideas to conform with their peers or superiors (or in rare cases, are willing to change them v...

Introduction: Mental health is a branch of science focused on promoting welfare, social welfare, and life health which is related to all periods (from birth to death) and aspects of life (family environment, school, university, appointment, and society). Personality is a collection of mental characteristics that consistently exists within individuals and influences their behaviors and thought...

Conformity as a research topic ori...

background: the pathogenesis of many diseases is correlated to irregularity in vascular endothelial growth factor (vegf) expression. results from several association studies show that variation in the level of vegf expression is related to polymorphic sequences within the vegf gene. additionally, there are many studies showing that some gene polymorphisms significantly influence the pharmacokin...

Youth who experience adverse environments in early life initiate sexual activity at a younger age, on average, than those from more advantaged circumstances. Evolutionary theorists have posited that ecological stress precipitates earlier reproductive and sexual onset, but it is unclear how stressful environments interact with genetic influences on age at first sex. Using a sample of 1,244 pairs...

Acute intermittent porphyria (AIP) has been associated with schizophrenia in some studies, but prior research is limited by the absence of comparison populations. Here, we linked Swedish registers to examine the risk of schizophrenia and bipolar disorder in 717 individuals diagnosed with AIP and their first-degree relatives, compared with matched individuals without AIP and their first-degree r...

Until recently, research in experimental atherosclerosis focused primarily on nutritional influences on plasma lipids, lipoproteins, and atherosclerosis. We review here the results of recent studies of independent and interactive influences of psychosocial and reproductive influences on atherosclerosis in nonhuman primates. These studies have produced evidence that, as in human beings, individu...

Models of Person X Situation influences on social behavior and judgement have invoked two distinct mechanisms: a personality disposition and a situational press. In this study we conceptualized both influences in terms of a single underlying mechanism, construct accessibility. We pitted the characteristic ways that individuals perceive others against situational influences on accessibility (i.e...

conclusions perceived social support is the most important factor that influences health-promoting behaviors. increasing social support by enhancing self-efficacy and decreasing perceived barriers can improve health-promoting behaviors among veterans. background health-promoting behaviors can enhance physical and mental health among individuals with disability, particularly veterans. objectives...
