- 在瘤学瘤学.
- 遗传学 是一个遗传学.
背景情况:
- 脑膜瘤是最常见的初级内瘤,约占所有脑瘤的三分之一.
- 单个患者多个脑膜瘤是罕见的,特别是不同的组织病理变异.
研究的目的:
- 为了研究遗传突变,瘤位置,组织学和克隆起源之间的关系,在罕见的情况下,多个脑膜瘤具有不同的亚型.

1.3K
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

20
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
