When the starlight from the GC reaches us, it may have passed through the spiral arms where star formation is actively occurring, diffuse regions, and dense regions of molecular clouds.
"They're actively working to try to diffuse it, and to pollute it".
Following substrate degradation inside individual lysosomes, the products diffuse or are actively transported to the cytosol for reutilization.
Molecules that reach the CNS via the transcellular pathway can diffuse passively, be actively transported by specific transporters, or undergo endocytosis [ 5, 6].
To enter the brain parenchyma and cross the BBB the substrates in the systemic circulation, molecules must either diffuse passively or transport actively across this barrier.
Drugs may diffuse passively or be actively transported across the barrier: in general, the higher the molecular weight and/or hydrophilicity, the more likely that passage across a membrane involves active transport [ 72].
Our model is based on only two factors, X and Y. Factor X is only produced in the soma, and it can diffuse, be degraded (inactivated) or be actively transported.
It is generally accepted that cargos smaller than ~40 kDa can slowly diffuse into the nucleus, while larger cargos are actively imported by karyopherins.
Hydrophilic statins are thought to be actively transported into hepatocytes by expressing OATP, whereas lipophilic statins diffuse nonselectively into extrahepatic tissues such as muscle (10).
It is possible that IDA could diffuse short distances in the apoplast of the AZ or be actively translocated across AZ cells.
