A mechanized urease activity assay

Enzyme and Microbial Technology, 2019
Two fully mechanized flow analysis systems for urease activity assays have been developed, characterized and compared. Both of them are based on almost the same compact system of solenoid micropumps and microvalves controlled and actuated by highly effective, low-power and economic Arduino microcontroller. For photometric detection of ammonia formed in

Mechanisms controlling CDK9 activity

Frontiers in Bioscience, 2006
This review primarily focuses on the mechanisms that modulate CDK9 activity and its recruitment to cellular genes, where it phosphorylates the C-terminal domain of RNA polymerase II (RNAPII) as well as negative elongation factors. CDK9 associates with each of four cyclins (T1, T2a, T2b and K), forming distinct positive transcription elongation factors (

MECHANISMS OF INFLAMMATION AND LEUKOCYTE ACTIVATION

Medical Clinics of North America, 1997
This article reviews the current status of the knowledge of mechanisms of activating inflammatory responses. It also describes inflammatory mediators, adhesion proteins, the inflammatory process itself, and the molecular mechanisms controlling inflammatory cell activation and regulation.

Mechanisms of Activation

1979
It is well known1–5 that molecules in gaseous media become activated in a direct collision between the translators. When a reference molecule undergoes collision with another molecule, the total kinetic energy of the two molecules is redistributed between them.

Mechanical Activation of Pharmaceutical Systems

Pharmaceutical Research, 1985
Mechanical activation has become a phenomenon of general significance in pharmaceutics. This report describes the extent of activation induced by relevant processes. With the use of the Eyring equation the transformation of structurally stored energy into chemical energy and the implied free enthalpy as well as the excess free enthalpy (activity) were ...

Principles and mechanisms of CD95 activation

Biological Chemistry, 2014
Abstract CD95 (Apo1/Fas) has been originally identified as the target of cell death-inducing antibodies. The recognition of CD95 as an apoptosis-triggering receptor represents one of the early milestones in the apoptosis field. Moreover, the research on CD95-induced cell death fostered various other discoveries of broad and general relevance in cell ...

An active process in cochlear mechanics

Hearing Research, 1983
A model for cochlear mechanics is proposed to take account of its two systems, one passive and one active. The classical passive system stimulates the inner hair cells directly at levels above about 40 dB SL. At intensities below about 60 dB an active process, the 'cochlear amplifier' (CA), somehow provides additional energy that enhances the vibration

Physiological mechanisms of TRPC activation

Pflügers Archiv - European Journal of Physiology, 2005
TRPC (canonical transient receptor potential) channels are vertebrate homologs of the Drosophila photoreceptor channel, TRP. Considerable research has been brought to bear on the seven members of this family, especially with regard to their possible role in calcium entry.
