Acoustic measurement: A tutorial for molecular biologists

Brain Research, 2006
Although skilled in in vitro techniques, the molecular biologist may not understand the finer points of acoustical measurement. Measurement is necessary whenever the auditory system function is being measured using the auditory brainstem response (ABR) or distortion product otoacoustic emissions (DPOAE) or is being challenged by a noise exposure.

Acoustic properties and molecular light scattering in alcohols

Journal of Molecular Liquids, 1999
Abstract The acoustic properties of alcohols with both weak and strong H-bonds are studied. The special attention is paid to the description of the association process in alcohols with well-developed H-bond network. The peculiarities of Brillouin and depolarized light scattering are considered.

Experiments in Molecular Physics with an Acoustic Interferometer

American Journal of Physics, 1973
An acoustic interferometer provides an inexpensive means for making precise studies of the kinetics of gas molecules. Two experiments are described: (1) Measurement of the vibrational relaxation time of gas molecules and (2) determination of intermolecular (van der Waals) forces in molecules.

New frontiers in molecular acoustics of liquids

The Journal of the Acoustical Society of America, 1994
The major accomplishments in molecular acoustics of liquid systems are summarized. The most promising direction in this field is acoustical thermodynamics. The possibility of acoustical evaluation of thermodynamic parameters of liquids comes from the fact that compressibility of the fluid is the second derivative of Gibbs free energy on pressure ...

Molecular acoustics in thermodynamic characterization of proteins

The Journal of the Acoustical Society of America, 1995
Processes such as conformational phase transitions, ligand binding events, and enzymatic catalysis alter the structure of proteins as well as the nature of their solvent accessible surface. Consequently, these processes result in corresponding changes in the sound velocity of the protein solution.

On the molecular kinetics of acoustic cavitation and the nuclear emission

Fuel and Energy Abstracts, 2003
Abstract A molecular kinetic theory has been developed for the acoustic bubble implosion that induces D–D fusion by irradiating the pulsed neutron beam, which was discovered recently by the Oak Ridge National Laboratory Group with deuterated acetone (C3D6O).

Triacylglycerols Characteristic of Porpoise Acoustic Tissues: Molecular Structures of Diisovaleroylglycerides

Science, 1972
More than two-thirds of the triacylglycerols from the acoustic tissues of the porpoise ( Tursiops gilli ) consist of 2 moles of isovaleric acid for every 1 mole of long-chain acids. Cranial blubber, which has no distinct acoustic function, does not contain these unusual glycerides.

Profiling molecular interactions using label-free acoustic screening

Drug Discovery Today: Technologies, 2005
As a result of more and more researchers becoming interested in proteins as potential therapeutic drug candidates, there is an increasing requirement for quick and accurate characterization of their interactions with each other and with target receptors.

Treatment of Acute Acoustic Trauma with Low Molecular Weight Dextran

Practica Oto-Rhino-Laryngologica, 2010
Ten workers struck by the same blast of an explosion were selected for a comparative study: 5 patients were treated with low molecular weight dextran, 5 patients were left without treatment. Recovery from the inner ear damage, measured by the restoration of hearing losses (bone conduction threshold), proved significantly better in the treated group ...

Molecular acoustic as a new tool for the study of biophysical properties of lipoproteins

Biophysical Chemistry, 1997
The method of measurement of velocity and absorption of ultrasound at a fixed frequency (7.2 MHz) and measurement of density were used to study the physical properties of high- (HDL3) and low- (LDL) density lipoproteins. We found substantial changes in velocity number [u] and absorption number [alpha lambda] on temperature, which reflect structural ...
