Neuroimaging of focal cortical dysplasia: neuropathological correlations.
Focal cortical dysplasia is a well-known cause of intractable epilepsy with early onset of seizures, and is potentially amenable to surgical therapy. It was first described by Taylor in 1971 as a peculiar malformative disorganisation of the neocortex characterised at histology by loss of cortical lamination and accompanied by giant, dysmorphic neurones and, most frequently, by "balloon cells" l...
متن کاملFocal cortical dysplasia: neuropathological subtypes, EEG, neuroimaging and surgical outcome.
Since the original description by Taylor, the term focal cortical dysplasia has been used to refer to a wide range of alterations of the cortical mantle. More recently, these conditions have been described from neuroimaging, neuropathological and genetic standpoints, generating several classifications. It is widely recognized that these classifications are unsatisfactory. We propose a simplifie...
متن کاملL-2-hydroxyglutaric aciduria: clinical, neuroimaging, and neuropathological findings.
BACKGROUND l-2-Hydroxyglutaric aciduria is a rare, infantile-onset, autosomal recessive organic aciduria affecting exclusively the central nervous system. To our knowledge, only 1 complete report of the neuropathological findings in an adult has been published. OBJECTIVE To present the clinical, neuroimaging, and neuropathological findings of l-2-hydroxyglutaric aciduria. DESIGN Case report...
متن کاملEfficient quantification of afferent cochlear ultrastructure using design-based stereology.
The afferent synapse between the auditory nerve fiber and the inner hair cell (IHC) represents a critical junction for hearing. Elucidation of the structure at this site will help establish the substrate for normal sound encoding as well as pathologic processes associated with hearing dysfunction. Previous applications of unbiased (design-based) stereological principles have expanded our knowle...

1.1 組織標本を使用する定量解析が抱える諸問題 組織標本の解析は定性的な所見から始まる.顕微鏡を用いた丁寧な観察によって初めて得られる検体の 大きさや分布,形態などについての詳細な情報は,全ての研究の基礎となるべき重要なものである.しか しながら,定性的なデータだけでは,統計学的な検討が難しく,結果が主観的なものになりやすい.この ため,生理的組織と病的組織の比較など,さらなる研究を行う際には,定量的なデータが必要になる.定 量解析の基本的な命題は,いかにして検体の正確な数を客観的に求めることができるか,ということであ る.組織標本に基づく定量解析は単純に思われるが,正確なデータを得ることは実は容易ではない. 最大の問題は,サンプリングバイアスである(図1).これは,標本抽出の際に母集団を代表していない 検体が選ばれるために生じる偏りのことであり,2次元的な切片を使って定量解析を行...
