Tubal compliance--changes with age and in tubal malfunction

It is known that eustachian tubal compliance has influence on the tubal function. We applied the direct measurement method to ascertain whether or not aging and tubal diseases are related to the compliance of the cartilaginous part of the eustachian tube. We developed a method for directly measuring tubal compliance by inserting a balloon catheter, which is inflated with water, into the eustachian tube and comparing the change in balloon pressure with the balloon volume. This method is advantageous in that one can directly measure tubal compliance in the cartilaginous part of the eustachian tube. Using this method we examined tubal compliance in 16 normal young volunteer ears, 21 normal elderly volunteer ears, 11 elderly ears with patulous tube and 12 elderly ears with stenotic tube including otitis media with effusion. In adults the tubal compliance increases in value with age. Tubal compliance of the elderly patulous tube was significantly higher than that of the normal elderly one, on the other hand the compliance of the elderly stenotic tube was significantly lower than that of the normal one. Tubal compliance was considered to be changed with aging and influence of the patulous and stenotic tubes.

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 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.

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.
