Biophysical chemical aspects of cellular cryobehavior
Biophysical Chemistry, 1988Freezing tolerance and resistance in nature are among the most important and challenging aspects of biochemical adaptation to extreme environments. Some biochemical strategies are known but their mechanism is still poorly understood. Cryopreservation of cells and tissues of sensitive organisms is still generally based on physical chemistry rather than ...

The Biophysical Basis of Cellular Sentience
2023Abstract Cellular sentience is essential for cellular evolution, coterminous with the origin of life. Placing evolution into a framework of cellular sentience grants a contextual understanding of the full range of challenges to which cells are continually exposed and better explains how relevant adaptive responses are achieved at all ...

Computational tools for cellular scale biophysics
Current Opinion in Cell BiologyMathematical models are indispensable for disentangling the interactions through which biological components work together to generate the forces and flows that position, mix, and distribute proteins, nutrients, and organelles within the cell. To illuminate the ever more specific questions studied at the edge of biological inquiry, such models ...

Total internal reflection fluorescence: applications in cellular biophysics
Current Opinion in Biotechnology, 1997Molecular interactions occurring on or near cell membrane surfaces are expected to have different properties from those occurring in bulk solutions. One particularly useful technique for studying surface-associated processes at the molecular level is total internal reflection fluorescence.

Teaching Biophysics II. Biophysical approach of transport through cellular membranes
Romanian Reports in PhysicsCellular metabolism implies a permanent transport through membranes of a great diversity of particles (e.g., ions, molecules, macromolecules, protein vesicles, etc.) in and out of the cells. The transport phenomena can be classified as passive (down the concentration gradients, driven solely by thermal agitation) or active (against the concentration ...

Two-photon excitation microscopy in cellular biophysics
Proceedings, annual meeting, Electron Microscopy Society of America, 1995Two-photon excitation microscopy (TPEM) provides attractive advantages over confocal microscopy for three-dimensionally resolved fluorescence imaging and photochemistry. Two-photon excitation arises from the simultaneous absorption of two photons in a single quantitized event whose probability is proportional to the square of the instantaneous ...

Cellular and Biophysical Applications of Genetic Code Expansion
Chemical ReviewsDespite their diverse functions, proteins are inherently constructed from a limited set of building blocks. These compositional constraints pose significant challenges to protein research and its practical applications. Strategically manipulating the cellular protein synthesis system to incorporate novel building blocks has emerged as a critical ...

Mathematical biophysics of cellular forms and movements
The Bulletin of Mathematical Biophysics, 1941Rashevsky's equations for describing the joint variation of cell shape and concentration of a metabolite are discussed. Conditions for the existence of non-spherical equilibria and the location of these are obtained and involve only two parametersa andA.
