An artery has many masters.
D uring the last 25 years, a large number of stimuli have been reported to alter the tone of the coronary arteries. Arterial caliber is now known to be affected by the distending pressure, by factors external to the artery (e.g., neural stimulation and humoral substances in the blood perfusing the arterial wall), by the substances produced by the arterial endothelium, and by metabolically media...
متن کاملExocytosis: The Many Masters of the Exocyst
The exocyst is a conserved eight-subunit complex involved in the docking of exocytic vesicles. The exocyst has now been identified as an effector for five small GTPases, including Sec4, Rho1, Rho3, Cdc42 and, most recently, RalA.
متن کاملActivity is a slave to many masters
Dopamine neurons in the midbrain have a central role in generating cycles of biological activity with periods as short as 4 hours and as long as 100 hours.
متن کاملCytoplasmic dynein heavy chain: the servant of many masters
Cytoplasmic dynein is the main retrograde motor in all eukaryotic cells. This complex comprises different subunits assembled on a cytoplasmic dynein heavy chain 1 (DYNC1H1) dimer. Cytoplasmic dynein is particularly important for neurons because it carries essential signals and organelles from distal sites to the cell body. In the past decade, several mouse models have helped to dissect the nume...
متن کاملKeisler’s Order Has Infinitely Many Classes
We prove, in ZFC, that there is an infinite strictly descending chain of classes of theories in Keisler’s order. Thus Keisler’s order is infinite and not a well order. Moreover, this chain occurs within the simple unstable theories, considered model-theoretically tame. Keisler’s order is a central notion of the model theory of the 60s and 70s which compares first-order theories (and implicitly ...
