背景:
- 過剰体重 (OW) の個体における白質 (WM) の微細構造の変化に関する研究は限られている.
- これらの変化を理解することは,OW集団における認知健康の評価に不可欠です.
研究 の 目的:
- 標準体重 (SW) とOWの参加者の間のWMの微細構造の違いを調査する.
- OWにおけるWMの整合性,認知領域,およびプラズマバイオマーカーの関係を調査する.
主な方法:
- ニューライト指向分散と密度イメージング (NODDI) と拡散テンサーイメージング (DTI) をWMの整合性を評価するために利用した.
- SWとOWのグループ間のNODDIとDTIメトリックの関心地域 (ROI) 値の比較
- 認知評価とプラズマバイオマーカーと相関するWMマイクロ構造メトリック.
主要な成果:
- 微分アニソトロピー (FA) とオリエンテーション分散指数 (ODI) の有意な差異は,広範囲のWM領域 (p < 0. 05) で観察された.
- 無シナット筋 (UF) のNODDIパラメータは,認知領域と有意に相関していた.
- 他のWM微細構造の異常は,認知機能とプラズマバイオマーカーと関連していました.
結論:
- WMの微細構造の異常は,OW状態の特徴です.
- これらの変化は認知機能と関連するプラズマバイオマーカーと明らかに関連しています.

01:52Regression Toward the Mean
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
02:55Stereotypes, Prejudice, and Discrimination
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who are...
01:29Social Identity
Social identity constitutes a significant aspect of an individual’s self-concept, shaped by membership in various social groups, including gender, nationality, ethnicity, sexual orientation, and political affiliation. Individuals associate specific traits with particular social groups, leading to internalization of these traits. For example, musicians are often perceived as creative, while women are frequently associated with nurturing tendencies. Once individuals identify with a particular...
01:29Self-Discrepancy and Its Effects
Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...
01:26Self-Esteem and Culture
Self-esteem, a core psychological construct, is intricately shaped by cultural context and varies significantly between collectivist and individualistic societies. In collectivist cultures such as Japan, self-esteem tends to be flexible, context-sensitive, and influenced by relationships. A Japanese student, for instance, may show restraint in formal settings like school but behave more openly among close friends, reflecting the flexible and dynamic nature of self-concept in such...
01:29Dark Triad and Person Perception
Person perception is influenced by both external behaviors and the observer’s internal characteristics, including personality traits. Individuals with dark personality traits, comprising psychopathy, Machiavellianism, and narcissism — collectively known as the dark triad – exhibit manipulative and exploitative tendencies in social contexts. These traits affect how they perceive others and how they are perceived.The Role of Dark Personality Traits in Person PerceptionBlack et al. (2014) explored...
