Centrifuge

centrifugeultracentrifuge
speed~1,000,000 g (approx. 9,800 km/s²),
Even smaller particles
separation Particles of ≤5 uM, ii) inflammasome: ~0.45 uM in diameter (~700 kDa),

Olga: A typical standard procedure in a trial is to centrifuge CSF briefly after collection, at slow speed; just to remove cell debris etc: This accommodates most soluble biomarkers we would want to look at, but I suppose no centrifugation could be accommodated if really needed, however - I am more concerned in your case in how reliable the measurement is if it goes away with even very mild centrifugation and whether or not the signal comes from just debris and is not biologically relevant. in vitro 에서 specificity 의 증명할 방법이 없으니, 이 signal 이 debris 에서 나온 것 아니냐?--> human CSF sample 으 까지 characterization 해도 이거 됨 ( 외 안 되냐?)

Typically purification of oligomeric/fibrillar species from biomaterials such as even brain lysates requires super high centrifugation speeds for prolonged periods of time so I am a bit suspicious here.

Circuits

Direct pathway

  • overall, stimulate thalamus and thus cortex (외우는 법: 서스지쌀코, 이중 스지 가 inhibitor)
  • ↑ SNc → ↑ D1 MSNs in striatum → (↑ GABA release onto GP) → ↓ [Gpi & SNR] (SNc 아니니 혼동말자) → thalamus 를 억제하는 Gpi 를 억제하므로 thalamus 자극됨 → ↑ cortex 자극 → ↑ movement.

아래 그림은 정상적인 direct pathway

  • PD 에서는 위 과정이 반대로 됨, 그런데 Ach interneurons are still inhibiting the striatal cells. (2012 #2007) 위 그림 보면 아래의 ‘이 선 blue’ 는 오기가 아님을 알 수 있음.

이 선 blue 의 오기?
