概括
乳腺癌骨转移的LyticX射线图案更常见的是HER2阳性,并具有高的Ki-67指数. 这种IHC概况可以预测骨并发症并指导治疗.
科学领域:
- 在瘤学瘤学.
- 病理学 病理学 病理学
- 放射学 放射学是一门学科.
背景情况:
- 了解乳腺癌 (BC) 骨转移 (SM) 行为是诊断和治疗的关键.
- 关于SM的免疫组织化学 (IHC) 概况及其与放射特征的联系的数据有限.
- 这项研究调查了BCIHC标记物和SMX射线图案之间的关联.
研究的目的:
- 评估雌激素受体 (ER),孕激素受体 (PR),HER2受体状态和Ki-67增殖指数与BC患者中MS的放射性呈现之间的关系.
- 为了比较光学和混合SM放射图案之间的IHC档案.
主要方法:
- 从单个BC患者中分析了185个SM样本.
- 对ER,PR,HER2和Ki-67的IHC表达的确定.
- 将IHC配置文件与X光图案进行比较 (光学与混合).
主要成果:
- 炎症转移 (66/185) 显示HER2阳性明显高于混合病变 (119/185).
- 炎症转移的Ki-67指数显著更高 (切线25:敏感性92.98%,特异性89.84%).
- 两组之间没有发现ER或PR表达的显著差异.
结论:
- 来自BC的MS与光放射表现更有可能是HER2-阳性,Ki-67指数>25.
- 评估SM IHC状态可以识别患有骨并发症风险较高的患者,如骨折.
- IHC分析可能有助于个性化手术和全身治疗规划,用于SM的BC患者.

Self-Presentation
313
Self-presentation is a fundamental aspect of social interaction, shaping both how others perceive individuals and how they view themselves. This dynamic process influences behaviors in various social settings, often leading people to adjust their appearance, speech, and demeanor to align with their desired identity. While self-presentation can be deliberate or unconscious, it plays a critical role in interpersonal relationships and self-perception.Forms of Self-PresentationSelf-presentation can...

Self-Presentation: Self-Monitoring and Self-Handicapping
44.7K
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Strategies of Self-Presentation I: Strategic Self-Presentation
211
Strategic self-presentation refers to individuals' intentional efforts to influence how others perceive them. This process is employed in various social and professional settings, such as job interviews, dating, politics, and legal contexts, where individuals seek to shape impressions to gain social or material advantages. While people generally present themselves in ways that align with their authentic characteristics, external factors, such as cognitive load, can hinder their ability to...

Processes of Self-Presentation
220
Effective self-presentation is a central component of social interaction and identity construction. It relies on the dynamic processes of defining the situation and engaging in self-disclosure. These mechanisms help individuals navigate social context expectations and manage how others perceive them, fostering mutual understanding and relationship development.Defining the SituationSocial situations are shaped by collectively understood frames—a set of widely understood rules or...

Strategies of Self-Presentation II: Self-Verification
187
Self-verification is a fundamental psychological drive wherein individuals seek affirmation of their self-concept from others, striving for consistency between their internal self-view and external perceptions. This drive operates even when the self-concept is negative, influencing interpersonal behavior and feedback preferences in complex and often counterintuitive ways. Unlike the self-enhancement motive, which seeks positive evaluations, self-verification prioritizes coherence and...

Association Areas of the Cortex
9.2K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
