- 遗传学 是一个遗传学.
- 儿童心脏病学 儿童心脏病学
背景情况:
- 双动脉 (BAV) 是一种常见的先天性心脏缺陷.
- 胸腔大动脉损伤,包括上升大动脉动脉瘤,可能与BAV有关.
- PTEN基因变异与各种遗传综合征有关,但它们在胸腔大关节病变中的作用尚未得到充分证实.
研究的目的:
- 讨论一个独特的儿科病例,呈现双主动脉,严重的上升主动脉动脉瘤和一种致病性PTEN变体.
- 在这种情况下,评估PTEN变体和胸部动脉损伤之间的潜在因果关系.
- 强调心血管遗传学中仔细的基因型-表型相关性的重要性.
主要方法:
- 案例报告的呈现方式.
- 审查关于BAV相关的动脉动脉病和PTEN相关疾病的现有文献.
- 对临床,成像和组织病理学发现的分析.
主要成果:
- 该患者表现出严重的上升性大动脉动脉瘤与双管大动脉和一种致病性PTEN变体结合.
- 大动脉表型和组织病理学与BAV相关的大动脉病变相一致.
- 根据目前的证据,无法确定PTEN损失和观察到的胸部动脉瘤之间的直接因果关系.
结论:
- 在这个孩子身上,BAV,大动脉动脉瘤和PTEN变体的同时发生是非常罕见的.
- 目前的证据不支持PTEN损失作为胸部动脉损伤的直接原因.
- 这些发现强调了需要谨慎地解释基因型-表型关系的必要性,并表明PTEN在大动脉疾病中的作用仍然是推测性的.

Self-Presentation
327
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
44.8K
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
229
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
255
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...

Mutation, Gene Flow, and Genetic Drift
64.6K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).
