Xanthochromia, from the Greek xanthos (ξανθός) "yellow" and chroma (χρώμα) "colour", is the yellowish appearance of cerebrospinal fluid that occurs several hours after bleeding into the subarachnoid space caused by certain medical conditions, most commonly subarachnoid hemorrhage. [1]
Froin's syndrome – coexistence of xanthochromia, high protein level and marked coagulation of cerebrospinal fluid (CSF). It is caused by meningeal irritation (e.g. during spinal meningitis) and CSF flow blockage by tumour mass or abscess. [1]
Cerebrospinal fluid (CSF) is a clear, colorless transcellular body fluid found within the meningeal tissue that surrounds the vertebrate brain and spinal cord, and in the ventricles of the brain. CSF is mostly produced by specialized ependymal cells in the choroid plexuses of the ventricles of the brain, and absorbed in the arachnoid ...
In quantum chemistry, a configuration state function (CSF), is a symmetry-adapted linear combination of Slater determinants. A CSF must not be confused with a configuration . In general, one configuration gives rise to several CSFs; all have the same total quantum numbers for spin and spatial parts but differ in their intermediate couplings.

Cerebrospinal fluid (CSF) flow MRI is used to assess pulsatile CSF flow both qualitatively and quantitatively. Time-resolved 2D phase-contrast MRI with velocity encoding is the most common method for CSF analysis. [ 1 ]
[21] [22] Downstream of the glymphatic system's waste clearance from the ISF to the CSF, the meningeal lymphatic system drains fluid from the glymphatic system to the meningeal compartment and deep cervical lymph nodes; this is shown by the draining of fluorescent dyes injected intracisternally into the CSF in mice. [21]
"Collapse" means the sudden process which the state of the system will "suddenly" change to an eigenstate of the observable during measurement. Eigenstates An eigenstate of an operator A {\displaystyle A} is a vector satisfied the eigenvalue equation: A | α = c | α {\displaystyle A|\alpha \rangle =c|\alpha \rangle } , where c {\displaystyle c ...
