概括
前足球运动员显示突形态变化,与头部冲击相关的较浅的上部额头突. 这可能表明突变是慢性创伤性脑病变风险的潜在生物标志物.
科学领域:
- 神经科学是一个神经科学.
- 放射学 放射学是一门学科.
- 运动医学 运动医学
背景情况:
- 重复的头部冲击 (RHI) 与慢性创伤性脑病 (CTE) 有关,这是一个经死后诊断的神经退行性疾病.
- CTE的特征是异常的陶蛋白积累,特别是在上额头中.
- 硫形态变化,如扩大和浅化,可以作为CTE风险的体内生物标志物.
研究的目的:
- 与对照人群相比,研究前足球运动员与前足球运动员的状形态差异.
- 检查形态与年龄,足球暴露和CTE相关标志物等因素之间的关联.
- 探索状形态作为RHI相关的大脑变化的潜在成像生物标志物.
主要方法:
- 分析了169名前足球运动员和54名对照者的结构性MRI数据.
- 使用 CalcSulc 量化在上额头和后额头角的硫深度和宽度.
- 统计模型评估了群体差异和与暴露变量和临床/成像数据的关联.
主要成果:
- 前足球运动员与对照者相比,左上额头突深度明显较浅.
- 早些时候的足球接触和更长的职业生涯与更宽的左角角相关.
- 较高的累积头部冲击暴露与左上额头深度的减少有关.
结论:
- 硫形态,特别是在上额头硫,可能反映累积的RHI暴露.
- 硫形态变化显示出作为CTE风险的体内生物标志物的潜力.
- 需要进一步的验证研究来确认硫形态作为可靠的生物标志物.

01:22Sutures of the Skull
10.1K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:26Bone Markings
7.9K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

01:14Cranial Bones: Superior and Posterior View
4.9K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:27Cranial Bones: Lateral View
4.3K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
