Morphometric Analysis of the Facial Profile: Contour of the Side Face and its Variations

The Journal of Craniofacial Surgery

Abstract

Much research has been conducted on the morphological characteristics of the Chinese. However, very few facial measurements have been documented, especially of the side face. This study uses geometirc morphometric method to analyze the contour and variations of the side face in Bai and Yi ethnic minorities from Yunnan province, China. The mark collection proves that for the Bai ethnicity, the variations of the nose are comparatively large, while the forehead variations are small. Variations around the lips and the chin are the largest. For the Yi ethnicity, the forehead also witnesses small variations and the nose again has large variations. The area around the glabella has large variations. Through the comparisons, the area around the glabella tends to extrude more in males both in Bai and Yi. The situation, however, is much more different when it comes to the trichion landmark collection where we see an apparent intrusion in males. For the trichion, Yi people are more intruded than the Bai. Similarities between Bai and Yi are demonstrated by principal component analysis: one can roughly set the males apart from the females using the vertical axis. Profile at the end of horizontal axis suggests that the female facial profile h...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.
