In summary, while the existing evidence points toward a beneficial role for GA in liver disease, the consistent positivity should be interpreted with caution, likely reflecting a combination of genuine therapeutic activity, methodological limitations, and publication bias
These include (1) their complex but somewhat similar primary structures (i.e., the length of the acyl chain and the amount of double bond within, (2) their rapid and dynamic transport within and across membranes, (3) their rapid metabolic interconversions, (4) their transient, and typically substoichiometric interactions with proteins and other macromolecules, either in a noncovalent manner or by covalent attachment (e.g., as protein posttranslational modifications), and (5) how these multiple parameters coordinate to lead to specific phenotypes
The conventional view of neural signaling is that a neuron (pre-synaptic) can influence its target cell (post-synaptic) by exciting or inhibiting it
Without cilia to propel mucus up the airway, mucus would follow the force of gravity and pool in the lower airways requiring the backup cough mechanism to clear (Mller et al., 2006)
