概括
主要侧面硬化症 (PLS) 是一种运动神经元疾病,主要影响上部运动神经元. 新证据表明较低的运动神经元参与,模糊了PLS和肌缩侧面硬化症 (ALS) 之间的界限.
科学领域:
- 神经学 神经学
- 神经退行性疾病 神经退行性疾病
- 运动神经元疾病 运动神经元疾病
背景情况:
- 初级侧面硬化症 (PLS) 的特点是纯上部运动神经元 (UMN) 退化,约占运动神经元疾病的3%.
- 通常情况下,PLS的预后不如肌缩性侧面硬化症 (ALS) 严重,因此早期区分至关重要.
- 经典的区分依赖于PLS中较低的运动神经元 (LMN) 系统被省略,与ALS不同.
研究的目的:
- 研究被诊断患有初级侧面硬化症 (PLS) 的患者下部运动神经元 (LMN) 系统的潜在参与.
- 根据新出现的证据表明LMN损伤,重新评估PLS的诊断标准.
主要方法:
- 对PLS患者的临床和补充检查数据的审查.
- 对现有文献和证据分析关于PLS中的LMN系统功能.
- 在PLS和ALS之间对临床表型的比较研究.
主要成果:
- 虽然传统上UMN占主导地位,但大量证据表明,LMN系统在PLS中可能受到损害.
- 这一发现挑战了仅仅基于LMN参与的PLS和ALS之间的严格分离.
结论:
- 初级侧面硬化可能并不总是以纯粹的UMN状况出现.
- PLS可以被认为是肌缩侧面硬化症 (ALS) 的表型,主要涉及UMN.
- 需要进一步的研究来完善诊断标准,并了解运动神经元疾病的范围.

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Anorexia Nervosa
59
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Panic Disorder
106
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...

Neural Regulation

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.
