Abstract

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is one of the most common sleep disorders that have significant associated health costs. It is caused by recurrent occlusion of the upper airway during sleep. Recently, many researchers have provided evidence that patients with OSAHS tend to have a large tongue, a comparatively prolonged soft palate, and a narrow upper airway.There are many therapeutic methods for OSAHS, although determining the obstructive points is very important. Several methods to study the morphology of the upper airway in patients with OSAHS are available: acoustic reflection, fluoroscopy, endoscopic observation, and computed tomography (CT). After our hospital took the lead in the introduction the first 320-detector CT in East China, our team studied the morphology of the upper airway in patients with OSAHS using this 320-detector CT.From July 2010 to July 2011, the upper airway of 66 patients with OSAHS and 22 control subjects were scanned using a 320-detector CT scanner at the time of deep inspiration, deep expiration, normal respiration, and Müller maneuver. Cross-sectional areas of the upper airway at the nasopharyngeal, velopharyngeal, and tongue-pharyngeal levels were measured and compared. Mean vel...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.
