Compliance of the eustachian tube in patients with otitis media with effusion

To analyze the compliance of the eustachian tube, we measured the decrease in tubal resistance (pressure/air flow) with increasing air flow rate through the eustachian tubal lumen. When the eustachian tube is compliant, the tubal resistance decreases greatly because of the high distensibility of the tube. The tubal compliance index (TCI), which is the ratio of the tubal resistance between two different air flow rates, was compared among three groups: 36 ears of children with otitis media with effusion (OME), 26 ears of adult OME patients, and 10 otherwise normal ears with traumatic perforations of the eardrum. Compared with normal subjects, OME children had a significantly higher TCI (P less than .005), whereas OME adults had a significantly lower TCI (P less than .05). From these results, we concluded that eustachian tubes are compliant in children with OME but rigid in adults with OME.

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.

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.

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.
