By assessing pain in response to repetitive or different types of standardized stimuli, dynamic quantitative sensory testing (QST) can reveal changes in the central processing of pain. We present methods to optimize and individualize two dynamic QST measures: temporal summation (TS) and conditioned pain modulation (CPM).

A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...

Differential dynamic microscopy (DDM) combines features of dynamic light scattering and microscopy. Here, the process of using DDM to characterize reconstituted cytoskeleton networks by quantifying the subdiffusive and caged dynamics of particles in vimentin networks and the ballistic motion of active myosin-driven actin-microtubule composites is presented.

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA It is rare nowadays that a whole year goes by without a major earthquake event wreaking havoc somewhere around the world. In some cases, like the 2005 Banda Ache earthquake in Indonesia, the damage involved large geographic areas and casualties in the six figures. In general, the number and intensity of earthquakes is not increasing, however, the vulnerability of the built environment is...
FAQs
Reaction rates in biochemical systems respond to both molecular abundance and surrounding conditions. Changing concentrations can alter reaction behavior, while temperature, catalysts, and environmental conditions modify the pace of chemical transformations. Examining these dependencies helps distinguish which variables control a process and supports mechanistic explanations of how biochemical systems respond.
Binding and dissociation events connect molecular recognition with system-level regulation. Their timing helps show how long interacting molecules remain associated and how readily a complex can form or separate. In biochemical analysis, following these events helps explain changes in activity, communication between proteins, and shifts in molecular organization rather than treating interactions as permanently fixed.
Conformational changes allow proteins to link structural movement with biochemical function. A change in molecular shape can accompany substrate transformation, alter how a protein communicates, or modify the organization of an interacting system. Considering these structural transitions is essential when a static molecular picture cannot explain enzyme behavior, pathway regulation, or protein signaling.
Researchers combine experimental and computational analyses to examine biochemical dynamics from complementary perspectives. Experimental observations provide time-dependent evidence of molecular behavior, whereas computational approaches help represent interactions, reactions, and structural changes in mechanistic models. Together, these approaches can connect measured changes with proposed explanations and clarify which processes may control system behavior.
Following changes as enzymes transform substrates can connect reaction behavior with pathway-level control. The same perspective helps identify how metabolic pathways are regulated over time rather than viewing each reaction in isolation. These analyses support mechanistic models that relate molecular events to broader biochemical function and clarify how regulation emerges from coordinated molecular activities.
Dynamic Processes support several research areas, including disease research, drug development, and the design of engineered biological systems. Their analysis can reveal how molecular changes contribute to biological behavior, guide mechanistic models of dysfunction or intervention, and help researchers design systems whose components respond through controlled structural, binding, or reaction-based changes.
