Assessment of Formalin-Fixed Bovine Larynx Asymmetry Using Geometric Morphometry [PDF]

The Scientific World Journal
The vibrations of the larynx produce the voice. Little is known about morphology and the size of cattle larynx. The aim of the study was to quantify the shape asymmetry of the larynx in calves obtained postmortem using a geometric morphometric approach ...

Intrinsic velocity differences between larynx raising and larynx lowering.

PLoS ONE, 2023
In this study, 23 subjects produced cyclic transitions between rounded vowels and unrounded vowels as in /o-i-o-i-o-…/ at two specific speaking rates. Rounded vowels are typically produced with a lower larynx position than unrounded vowels. This contrast

The Effect of Tobacco Smoke N-Nitrosamines, NNK and NDEA, and Nicotine, on DNA Mismatch Repair Mechanism and miRNA Markers, in Hypopharyngeal Squamous Cell Carcinoma: An In Vivo Model and Clinical Evidence

Current Oncology, 2022
Deregulation of the DNA mismatch repair (MMR) mechanism has been linked to poor prognosis of upper aerodigestive tract cancers. Our recent in vitro data have provided evidence of crosstalk between deregulated miRNAs and MMR genes, caused by tobacco smoke

Trend and projection of larynx cancer incidence and mortality in China from 1990 to 2044: A Bayesian age–period–cohort modeling study

Cancer Medicine, 2023
Background Larynx cancer is one of the most common cancers in head and neck, and imposes heavy burden on individual and societies. A comprehensive understanding of the burden of larynx cancer is necessary to improve prevention and control strategies ...

The Effect of NNK, A Tobacco Smoke Carcinogen, on the miRNA and Mismatch DNA Repair Expression Profiles in Lung and Head and Neck Squamous Cancer Cells

Cells, 2020
Tobacco smoking is a common risk factor for lung cancer and head and neck cancer. Molecular changes such as deregulation of miRNA expression have been linked to tobacco smoking in both types of cancer.

Biliary tumorigenic effect on hypopharyngeal cells is significantly enhanced by pH reduction

Cancer Medicine, 2019
Biliary reflux has been considered a potential risk factor in upper aerodigestive tract malignancies. It is not yet clearly known how pH affects the bile‐induced activation of NF‐κB and its related oncogenic pathway previously linked to hypopharyngeal ...

A rare case of coin impaction in larynx in an adult

Clinics and Practice, 2011
Impaction of foreign body in larynx is reported exclusively in paediatric population only. Moreover impaction of coin in larynx has never been reported previously. With this background, we report a rare case of coin impaction in larynx in a healthy adult.

Rapid evolution of the primate larynx?

PLoS Biology, 2020
Tissue vibrations in the larynx produce most sounds that comprise vocal communication in mammals. Larynx morphology is thus predicted to be a key target for selection, particularly in species with highly developed vocal communication systems.
