Effects of the filter microstructure and ambient air condition on the aerodynamic dispersion of sneezing droplets: A multiscale and multiphysics simulation study.

Phys Fluids (1994) 2021 Jun 24;33(6):063317. Epub 2021 Jun 24.

UniAET Co., Ltd., Seoul 08502, South Korea.

Concerns have been ramping up with regard to the propagation of infectious droplets due to the recent COVID-19 pandemic. The effects of filter microstructures and ambient air flows on droplet dispersion by sneezing are investigated by a fully coupled Eulerian-Lagrangian computational modeling with a micro-to-macroscale bridging approach. Materials that are commonly applied to face masks are modeled to generate two different virtual masks with various levels of filtration efficiency, and the leakage percentages through the unsealed nose and cheek areas were set to 11% and 25%, respectively.

Physiol Res 2020 03;69(Suppl 1):S43-S54

Clinic of Dermatovenerology, Jessenius Faculty of Medicine in Martin, Comenius University in Bratislava, University Hospital in Martin, Martin, Slovak

Itch is the most common chief complaint in patients visiting dermatology clinics and is analogous to cough and also sneeze of the lower and upper respiratory tract, all three of which are host actions trying to clear noxious stimuli. The pathomechanisms of these symptoms are not completely determined. The itch can originate from a variety of etiologies. Read More

Dorsal and ventral aspects of the most caudal medullary reticular formation have differential roles in modulation and formation of the respiratory motor pattern in rat.

Brain Struct Funct 2016 12 11;221(9):4353-4368. Epub 2015 Dec 11.

Howard Florey Laboratories, Systems Neurophysiology Division, Florey Institute of Neuroscience and Mental Health, Gate 11 Royal Parade, University of Melbourne, Parkville, VIC, 3010, Australia.

The respiratory pattern generator of mammals is anatomically organized in lateral respiratory columns (LRCs) within the brainstem. LRC compartments serve specific functions in respiratory pattern and rhythm generation. While the caudal medullary reticular formation (cMRF) has respiratory functions reportedly related to the mediation of expulsive respiratory reflexes, it remains unclear whether neurons of the cMRF functionally belong to the LRC.

Department of Biochemistry, University of Oxford, South Parks Road, Oxford OX1 3QU, UK. Electronic address:

The influenza virus is surrounded by an envelope composed of a lipid bilayer and integral membrane proteins. Understanding the structural dynamics of the membrane envelope provides biophysical insights into aspects of viral function, such as the wide-ranging survival times of the virion in different environments. We have combined experimental data from X-ray crystallography, nuclear magnetic resonance spectroscopy, cryo-electron microscopy, and lipidomics to build a model of the intact influenza A virion.

Recognizing flu-like symptoms from videos.

BMC Bioinformatics 2014 Sep 12;15:300. Epub 2014 Sep 12.

Bioinformatics Institute, A*STAR, Singapore, Singapore.

Background: Vision-based surveillance and monitoring is a potential alternative for early detection of respiratory disease outbreaks in urban areas complementing molecular diagnostics and hospital and doctor visit-based alert systems. Visible actions representing typical flu-like symptoms include sneeze and cough that are associated with changing patterns of hand to head distances, among others. The technical difficulties lie in the high complexity and large variation of those actions as well as numerous similar background actions such as scratching head, cell phone use, eating, drinking and so on.

A one-dimensional model of the spinal cerebrospinal-fluid compartment.

J Biomech Eng 2012 Feb;134(2):021005

The Centre for Biomedical Engineering, University of Surrey, Guildford, United Kingdom.

Modeling of the cerebrospinal fluid (CSF) system in the spine is strongly motivated by the need to understand the origins of pathological conditions such as the emergence and growth of fluid-filled cysts in the spinal cord. In this study, a one-dimensional (1D) approximation for the flow in elastic conduits was used to formulate a model of the spinal CSF compartment. The modeling was based around a coaxial geometry in which the inner elastic cylinder represented the spinal cord, middle elastic tube represented the dura, and the outermost tube represented the vertebral column.

The clinical aspects of the acute facet syndrome: results from a structured discussion among European chiropractors.

Chiropr Osteopat 2009 Feb 5;17. Epub 2009 Feb 5.

Nordic Institute of Chiropractic and Clinical Biomechanics, Odense M, Denmark.

Background: The term 'acute facet syndrome' is widely used and accepted amongst chiropractors, but poorly described in the literature, as most of the present literature relates to chronic facet joint pain. Therefore, research into the degree of consensus on the subject amongst a large group of chiropractic practitioners was seen to be a useful contribution.

Allergic rhinitis-induced nasal congestion: its impact on sleep quality.

Authors:
William Storms

Prim Care Respir J 2008 Mar;17(1):7-18

The Research Center, The William Storms Allergy Clinic, Colorado Springs, CO 80907, USA.

Allergic rhinitis (AR) is an extremely common health problem affecting 20 to 40 million Americans and between 10-25% of the world's population. Patients with AR suffer from both nasal symptoms (congestion, rhinorrhea, itching, and sneezing) and ocular symptoms (itching, redness, and tearing). The negative impact on sleep quality and quantity, and consequently on various aspects of the patient's life, is an under-recognised and under-treated component of AR morbidity. Read More
