- 遗传学 遗传学 是一个
- 感官科学 感官科学
背景情况:
- 帕金森病 (PD) 是一种复杂的神经系统疾病.
- 阿尔法同核素 (α-synuclein) 和其遗传突变与PD易感性有关.
- 患PD的味觉障碍研究不足,关于其诊断和预后价值的发现不一致.
研究的目的:
- 与健康对照组 (HCs) 相比,研究PD患者的味觉异常.
- 探索特定α-synuclein基因 (SNCA) 多态和PD中的味觉障碍之间的关联.
- 通过监督学习来评估味觉和遗传标记在PD分类及其严重程度的有用性.
主要方法:
- 在PD患者和HC患者中评估了五种味觉刺激的味觉感知.
- 分析了四种SNCA单核酸多态 (SNPs) 与味觉感知之间的关联.
- 采用监督学习 (SL) 模型来分类PD与HC以及中度与高PD严重程度.
- 确定了人口,临床,遗传和感官特征对PD预测和分层的影响.
主要成果:

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.

1.7K
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.

Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
