This work reviews recent achievements made by our lab. on intercellular signal transduction related to the synthesis and action of steroids. These achievements were made possible by the high suitability of cytochrome P450, a key enzyme in signal transduction, to quantitative spectroscopic analysis.

Tissue Engineering Part B: Reviews, 2015
The unique mechanoelectrochemical environment of cartilage has motivated researchers to investigate the effect of multiple biophysical cues, including mechanical, magnetic, and electrical stimulation, on chondrocyte biology. It is well established that biophysical stimuli promote chondrocyte proliferation, differentiation, and maturation within ...

Biophysical and Molecular Features of Thermosensitive TRP Channels Involved in Sensory Transduction
2015Temperature is one of the physical variables that cells and biological organisms constantly monitor to achieve homeostasis and maintain chemical reactions at a suitable speed for the living environment to which they are adapted. In order to monitor and maintain temperature on a constant basis, thermosensitive molecules were selected during evolution ...

The temperate phage P1 is capable of excising fragments from the bacterial genome and including these fragments in P1 phage protein coats. By confining our attention to those particles containing the galactose gene of the bacterium, we examined events at the λ prophage attachment site.

A Biophysical Analysis of Mechano-electrical Transduction
1971This treatise is an attempt to approach some basic problems of biological excitability in terms of nonlinear oscillation theory applied to membrane systems where there is a coupling between electrical and mechanical forces. The basic concept assumes that the excitable membrane contains fixed charges, i.e., ionic membranes of ion-exchange character ...

Proceedings of the 2nd International Conference on Bioelectromagnetism (Cat. No.98TH8269), 2002
Describes an energy approach to the acupuncture phenomenon based on the bioenergetics of the cells in the body surface receptor "acupoints" following the signal transduction postulate in a biomolecular model. Using the gamma camera scintillation technique "Acupuncture Scintigraphy" with technetium pertechnetate, various minimal dose injection (25-200 ...

After a long rivalry with Hagins’ “calcium hypothesis” cyclic GMP is now solidly established as the cytoplasmic transmitter of the visual excitation process in the vertebrate photoreceptor1,2: in these cells cGMP directly controls the conductance of the Na+ channels in the plasma membrane; in this respect, the visual transduction process differs from ...

The Function of Membrane Glycerolipid Fatty Acyl Unsaturation in Signal Transduction and Cell Cycle Control: A Biophysical Approach [PDF]
, 1989 When describing the movement of suspended molecules of submicroscopic size in liquids, Einstein [1] has stated that classical thermodynamics cannot be looked upon as applicable with precision. Such molecules include amphiphilic membrane glycerolipids. Visual observation of the above mentioned submicroscopic particles was originally made by the botanist

A biophysical approach to sensory transduction by vertebrate hair cells
1980An in vitro preparation of the bullfrog sacculus was developed, in which the macular epithelium was arranged as a septum between two chambers. Hair cells are stimulated by moving the overlying otolithic membrane with a glass stimulus probe; the response is recorded as the transepithelial current with the epithelium voltage-clamped.
