Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

M-Mode Ultrasonography in Ocular Emergencies

International Journal of Research and Scientific Innovation, 2022
M-Mode, or time-motion display, allows a single beam to emit from the ultrasound transducer along a defined track in conjunction with a recorder that captures all motions that occurs along the path. This mode allows high temporal resolution, thus affording the examiner an excellent view of subtle motions.

M-mode echocardiographic values in sheep

American Journal of Veterinary Research, 1987
SUMMARY M-mode echocardiograms were recorded from 21 adult sheep (20 ewes, 1 whether). Fifteen echocardiographic measurements were taken and compared with body weights or heart rates, using linear regression equations. Significant correlations (P < 0.05) were found when body weight was compared with left ventricular internal dimensions in systole ...

Pitfalls and limitations of M-mode echocardiography

American Heart Journal, 1977
Newer diagnostic applications as well as the ability of obtaining physiologic information has resulted in a greater interest in echocardiography. As with any new technique, certain classical criteria have not been found to be as specific and diagnostic as was originally believed.

The M-mode echocardiogram in Fabry's disease

American Heart Journal, 1980
Fabry's disease results from deficient activity of the enzyme alpha-galactosidase A. Cardiac abnormalities result from glycosphingolipid deposition in the myocardium, valvular tissue, and vessel walls. A noninvasive method to examine these abnormalities would be useful in the evaluation of patients.

Auto-biometric for M-mode echocardiography

SPIE Proceedings, 2010
In this paper we present a system for fast and accurate detection of anatomical structures (calipers) in M-mode images. The task is challenging because of dramatic variations in their appearances. We propose to solve the problem in a progressive manner, which ensures both robustness and efficiency.

Ultrasonic M-Mode Technique in Ophthalmology

Archives of Ophthalmology, 1969
The use of the M-mode or time-dependent intensity modulated ultrasound technique for ophthalmologic investigations is described. This technique provides the investigator with a means for monitoring structural changes in the eye during physiologic or pharmacologic experimental conditions, or a combination of both, and is particularly useful in studying ...

Video controlled M‐mode biometry

Acta Ophthalmologica Scandinavica, 1995
ABSTRACT To increase the accuracy of intraocular lens power calculation, an interface between an ultrasonic A‐scanning device and a personal computer was created, allowing for an on‐line interpretation of the ultrasonogram in an M‐mode fashion. On the same computer display, a video recording of the movements of the transducer probe relative to the eye ...
