Sentences with phrase «cilia beating»

The cilia beating frequency varied across samples but the difference was typically within a few hertz.

Further increasing the formaldehyde concentration to 1 milligram per cubic meter led to a dramatic increase — up to 136.4 per cent — in cilia beating frequency relative to the baseline value.

By enabling the observation of cilia beating frequency, the experimental model described in this work provides more realism for clinical applications.

In contrast, when air mixed with 0.5 milligrams per cubic meter of formaldehyde was passed through the chamber, they observed a 7.4 per cent increase in cilia beating frequency relative to the baseline value.

At even higher formaldehyde concentrations of 3.0 milligrams per cubic meter, however, the researchers observed an unexpected decrease in cilia beating frequency, possibly due to irreversible cell damage caused by the formaldehyde.

When fresh air was passed into the chamber, the researchers observed a 3 per cent drop in cilia beating frequency relative to the baseline value.

Not exact matches

Wei Wang and Zhi Ping Wang at the A * STAR Singapore Institute of Manufacturing Technology, De Yun Wang at the National University of Singapore and co-workers have now developed the first microfluidic device that enables the direct observation of cilia and their beating frequency on a polyester membrane [1].

A paramecium moves by the beating of its cilia; an amoeba, by the streaming of its cytoplasm; a muscle, by its over-all contraction.

The beating rate of cilia could provide an additional tool to help decide time of death, especially if it was within the previous 24 hours.

They hope to use the cilia to judge time of death since not only does the beating slow gradually but it also seems relatively immune to environmental factors.

Since the beating of these cilia slows at a predictable rate, forensic teams should be able to estimate time of death more accurately.

RFX3 governs growth and beating efficiency of motile cilia in mouse and controls genes involved in human ciliopathies.

The respiratory system has defense mechanisms which protect the epithelium against bacterial infection and foreign particles / molecules from being deposited.29 These mechanisms can be summarized to the following: a) beating cilia, b) mucus, c) macrophages, d) transporters and e) enzymes.

An underlying respiratory disease such as; asthma, chronic obstructive pulmonary disease (COPD) and cystic fibrosis modifies these mechanisms by reducing the function of beating cilia and increasing the production of mucus.
