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 ...

The difference in accommodative amplitude and facility between the dominant and non-dominant eyes

Journal of the Pakistan Medical Association
The cross-sectional study was planned to compare the amplitude of accommodation and accommodative facility between the dominant and non-dominant eyes in young university students.

The influence of tinted lenses upon ocular accommodation

Vision Research, 2001
We determined the effect upon accommodative responses of tinted lenses prescribed for the relief of visual discomfort in a group of five long term lens wearers. Static and dynamic responses were measured under four viewing conditions (1) prescribed tinted lens (2) neutral density filter (3) tinted lens of complementary colour and (4) no absorptive lens.

Accommodation effects on peripheral ocular biometry [PDF]

, 2016
The effect of near work on the biometric properties of the eye, including the eye’s length and the thickness of the posterior vascular layer were investigated.

Relationship of ocular accommodation and motor skills performance in developmental coordination disorder

, 2015
Ocular accommodation provides a well-focussed image, feedback for accurate eye movement control, and cues for depth perception. To accurately perform visually guided motor tasks, integration of ocular motor systems is essential.

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,

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

FEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...

Latanoprost could exacerbate the progression of presbyopia.

PLoS ONE, 2019
PURPOSE:Prostaglandin analogues (PG) reduce intra-ocular pressure by enhancing uveoscleral flow at the ciliary body, which controls accommodation via the ciliary muscle.

Axial movement of the dual-optic accommodating intraocular lens for the correction of the presbyopia: Optical performance and clinical outcomes

Journal of Optometry, 2015
Presbyopia occurs in the aging eye due to changes in the ciliary muscle, zonular fibers, crystalline lens, and an increased lens sclerosis. As a consequence, the capacity of accommodation decreases, which hampers to focus near objects.

Caffeine alters the dynamics of ocular accommodation depending on the habitual caffeine intake

, 2019
Highlights • The lag of accommodative response while performing a 10-min attention task is insensitive to caffeine intake. • A single dose of caffeine induces a more stable accommodative response in high caffeine consumers ...
