Early Experiences with Crowdsourcing Airway Annotations in Chest CT [PDF]

open access: yesLABELS 2016, DLMIA 2016: Deep Learning and Data Labeling for Medical Applications pp 209-218, 2017
Measuring airways in chest computed tomography (CT) images is important for characterizing diseases such as cystic fibrosis, yet very time-consuming to perform manually. Machine learning algorithms offer an alternative, but need large sets of annotated data to perform well.

Dynamics of airflow in a short inhalation [PDF]

open access: yes, 2015
During a rapid inhalation, such as a sniff, the flow in the airways accelerates and decays quickly. The consequences for flow development and convective trans- port of an inhaled gas were investigated in a subject geometry extending from the nose to the ...

Factors related to mouth breathing syndrome in preschool children and the effects of incompetent lip seal: An exploratory study

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1555-1560, December 2022., 2022
Abstract Objectives A set of orofacial signs and symptoms completely or partially present in individuals who replace the correct pattern of nasal breathing with an oral or mixed pattern is defined as mouth breathing syndrome (MBS). In a previous report, it was clarified that an incompetent lip seal (ILS) affected the occurrence of MBS among primary ...

An Optoelectrically Switched, Dual‐Mode Neuromorphic Sensor for Transient and Accumulative Gas Detection

open access: yesAdvanced Functional Materials, EarlyView.
A transistor‐type carbon nanotube gas sensor with dual‐mode detection capability has been proposed. By simply adjusting the gate voltage and UV illumination, this sensor enables both real‐time detection and accumulation‐based sensing of toxic gases within a single device, providing a compact and adaptable platform for environmental monitoring ...

Interleukin 4, but not interleukin 5 or eosinophils, is required in a murine model of acute airway hyperreactivity. [PDF]

open access: yes, 1996
Reversible airway hyperreactivity underlies the pathophysiology of asthma, yet the precise mediators of the response remain unclear. Human studies have correlated aberrant activation of T helper (Th) 2-like effector systems in the airways with disease. A

The regulation of host defences to infection by the microbiota [PDF]

open access: yes, 2016
The skin and mucosal epithelia of humans and other mammals are permanently colonised by large microbial communities (the microbiota). Due to this life-long association with the microbiota, these microbes have an extensive influence over the physiology of

β‐1,3 Glucan Microparticles & Nanoparticles: Fabrication Methods & Applications in Immunomodulation & Targeted Drug Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
Beta‐glucans have gained significant attention as an immunomodulatory biomaterial with cell‐targeting capabilities. This review comprehensively outlines the design and fabrication methods for producing beta‐glucan particles at both the micro and nanoscale and their applications in immune cell targeting, immunomodulation, and drug delivery ...
