概括

周周血管空间 (DTI-ALPS) 的扩散张力图像分析显示,多发性硬化症 (MS) 患者的淋巴功能受损,残疾程度更高. 这种成像生物标志物与疾病严重程度和大脑健康相关,这表明淋巴功能障碍有助于MS进展.

科学领域:

神经成像是一种神经成像.
神经学神经学
生物标志物生物标志物

背景情况:

淋巴系统在多发性硬化症 (MS) 相关残疾中的作用尚未完全理解.
周周血管空间 (DTI-ALPS) 的扩散张力图像分析是一种评估淋巴功能的非侵入性技术.

研究的目的:

为了研究MS患者的淋巴功能,根据残疾程度分类.
评估DTI-ALPS指数与MS的临床和成像标志物相关的评估.

主要方法:

118名多发性硬化患者被分为较低 (MS-L) 和较高 (MS-H) 的残疾组.
进行了结构和扩散权重成像,以测量大脑辅酶体分数 (BPF),病变负载 (LL) 和DTI-ALPS指数.
后勤回归分析了BPF,LL和DTI-ALPS指数对残疾子组的预测值.

主要成果:

与MS-L组相比,MS-H组中观察到的DTI-ALPS指数明显较低.
DTI-ALPS指数与疾病持续时间和EDSS得分以及BPF负相关,而与LL的积极相关.
DTI-ALPS指数和LL是残疾子组的重要预测指标.

结论:

该DTI-ALPS指数作为一个潜在的成像生物标志物用于MS残疾.
淋巴系统损伤与MS病理有关,可能导致与疾病相关的残疾.
需要进一步的研究,以充分阐明淋巴系统在MS进展中的作用.

关键词:

Lysosomal Hydrolases

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
