- 放射化学 放射化学是指辐射化学.
背景情况:
- 帕金森病 (PD) 是一种神经退行性疾病,影响运动控制,包括步行.
- 涉及囊泡性乙胆载体 (VAChT) 的胆能通路与运动功能和认知有关.
- 在PD中,步行障碍是复杂的,前后行走可能依赖于不同的神经机制.
研究的目的:
- 调查胆固醇系统在帕金森病前后行走中的作用.
- 通过[18F]FEOBV正子发射断层扫描 (PET) 检查膀性乙胆载体 (VAChT) 可用性和步行表现之间的关联.
主要方法:
- 对44名帕金森病患者进行[18F]FEOBV PET扫描和步态评估的回顾性分析.
- 步行速度和[18F]FEOBV吸收之间的Voxel-wise相关性分析,控制药物和疾病持续时间.
- 线性回归和调解分析包括姿势不稳定和步态障碍 (PIGD) 症状和认知功能.
主要成果:

01:15Parkinson's Disease: Overview
710
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

3.1K
The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a vital role in relaying information and controlling critical life functions. It comprises three primary regions: the midbrain, pons, and medulla oblongata.
The Midbrain
The midbrain is located beneath the diencephalon and connects the cerebrum with the lower parts of the brain. The cerebral peduncles are prominent midbrain structures that house the...
