Abstract

To discuss the feasibility of endoscopic frontal sinus surgery in the nasal septum median path. (1) Sixty adult cadaveric heads fixed with formalin were CT scanned,and were three dimensional reconstruction. (2) Thirty adult cadaveric heads were sawn along the sagittal line close to the side of the nasal septum, then the important anatomic marks were observed and measured. (3) Combined with CT and anatomical data, thirty adult cadaveric heads were operated in different degree, and the damage of nasal septum and fila olfactoria were detected in the same time. (1) The roots of middle nasal concha were simulated in the endoscopic frontal sinus surgery. The operation time, operative procedures, markers foundation, endoscopic back of posterior border of frontal sinus foundation and attached to the symphysis with cribriform plate and the top of ethmoidal sinus were recorded. (2) The intersection point formed by the level of middle nasal concha and the vertical of middle nasal concha corresponded with the nasal septum was called the M point. The distance from the M point to the horizon of the nasal bone was (20.07 +/- 6.21) mm, the distance from the M point to the first fila olfactoria was (24.38 +/- 7.68) mm, the distance from the fir...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.
