PCNA is part of a sliding clamp which forms a ring which maintains the connection between polymerase and its DNA template, allowing uninterrupted synthesis.
In the second configuration, the so called 'single cantilever' experiment was performed: the sample was clamped between a fixed part and a mobile clamp which applies the force along the direction parallel to the pores and perpendicular to the plane of the membrane.
And also the baby's cord is cut in a good way here, and they put a cord clamp which holds well, it doesn't bleed.
Whereas the clamp model suggests that Pcs1/Mde4 complex itself acts as a molecular clamp which locks together microtubule attachment sites, an alternative model suggests that the Pcs1/Mde4 complex prevents merotely indirectly by recruiting condensin to kinetochores and that condensin acts as a molecular clamp which locks together microtubule attachment sites.
A cyclodextrin dimer has been used as both a catalyst (for the polymerization of δ-valerolactone) and a molecular "clamp", which guides the output of the polymer.
Stacks of Tupperware containers held antique laryngologic instruments, including a harpoon-like implement for shearing off diseased tonsils, and a curved metal forceps with an end clamp which was used, in the eighteen-eighties, to hold a cotton swab impregnated with liquid cocaine — an early method for subduing the gag reflex in patients.
OBJECTIVE Neurosurgery often requires skull immobilization with a Mayfield clamp, which often causes brief intense nociceptive stimulation, hypertension and tachycardia.
The quadriceps force was transmitted through a special clamp which was attached on the quadriceps tendon.
This paper is concerned with the design of a Cam-flexure clamp, which is a single-body, elastic structure to hold a slender tube with adequate force without using any fasteners.
A strength of this study is the use of a euglycaemic glucose clamp, which is considered as the 'gold standard' in determining pharmacodynamic properties of insulin [ 18].
