Ultrasound speed and attenuation in homogenates of bovine skeletal muscle

Ultrasonics
M O Woods, C A Miles

Abstract

The attenuation and speed of ultrasound were measured in homogenates of post-rigor bovine skeletal muscle, and found to increase in proportion to the concentration of muscle. Extrapolation of the data to tissue concentrations yielded an attenuation of 7.5 dB cm-1 at pH 5.7, 20 degrees C and 7.3 MHz. This was close to that measured in the minced tissue, 8.3 dB cm-1, and between values previously recorded across and along the fibres of intact muscle. Corresponding measurements for the speed of ultrasound in homogenates, extrapolated to the native tissue concentration, were: 1555 +/- 9 m s-1 at 0 degree C, 1592 +/- 10 m s-1 at 20 degrees C and 1616 +/- 9 m s-1 at 37 degrees C. These were not significantly different from measurements of minced muscle at the same temperatures. Measurements of the attenuation of 7.3 MHz ultrasound in suspensions of myofibrils indicated that attenuation by the myofibrils caused at least 64% of the attenuation in muscle homogenates at pH 5.7. Re-analysis of the viscous loss arising from relative movement of the myofibrils in their surrounding fluid, indicated that this mechanism could account for no more than 15% of the attenuation in muscle homogenates. Attenuation due to scattering was calculated to ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
