How Much Pigment Should Flowers Have? Flowers With Moderate Pigmentation Have Highest Color Contrast

Frontiers in Ecology and Evolution, 2021
Floral pigments are a core component of flower colors, but how much pigment a flower should have to yield a strong visual signal to pollinators is unknown.

Visual and cognitive functioning among older adults with low vision before vision rehabilitation: A pilot study

Frontiers in Psychology, 2023
IntroductionThe occurrence of age-related vision changes is inevitable. However, some of these changes can become pathological. Research indicates that vision and hearing loss is correlated with age-related cognitive decline, and with a higher risk of ...

Dose‐dependent induction of epithelial‐mesenchymal transition in 3D melanoma models by non‐thermal plasma treatment

Molecular Oncology, EarlyView.
Non‐thermal plasma treatment of melanoma cells induced epithelial‐mesenchymal transition (EMT) in a dose‐dependent fashion. This report highlights the critical need to further investigate potential adverse effects of non‐thermal plasma for cancer therapy and to optimize treatment parameters for clinical translation. Despite the promising results of non‐

Acuity and contrast sensivity of infant vision

Nature, 1974
IF we are to study the development of form and space perception in man, it is necessary to know something of the basic visual capabilities of the developing human infant. There have been a number of investigations of visual acuity in the first few months of life.

Decrypting cancer's spatial code: from single cells to tissue niches

Molecular Oncology, EarlyView.
Spatial transcriptomics maps gene activity across tissues, offering powerful insights into how cancer cells are organised, switch states and interact with their surroundings. This review outlines emerging computational, artificial intelligence (AI) and geospatial approaches to define cell states, uncover tumour niches and integrate spatial data with ...

Next-generation vision testing: the quick CSF

Current Directions in Biomedical Engineering, 2015
The Contrast Sensitivity Function relates the spatial frequency and contrast of a spatial pattern to its visibility and thus provides a fundamental description of visual function.

Current trends in single‐cell RNA sequencing applications in diabetes mellitus

FEBS Open Bio, EarlyView.
Single‐cell RNA sequencing is a powerful approach to decipher the cellular and molecular landscape at a single‐cell resolution. The rapid development of this technology has led to a wide range of applications, including the detection of cellular and molecular mechanisms and the identification and introduction of novel potential diagnostic and ...

Diagnostic Challenge: The Case of a 70‐Year‐Old Man Who Presents With Progressive Vision Loss and Headaches

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT A 70‐year‐old presents with 6 weeks of progressive bilateral vision loss and headaches. He was also recently treated for presumed sciatica. His exam on admission is notable for poor visual acuity (no light perception), optic nerve atrophy bilaterally with swelling and disc hemorrhage on the left eye and left foot drop.

Effects of Contrast Sensitivity on Colour Vision Testing [PDF]

Neuro-Ophthalmology, 2017
This study analyses how contrast sensitivity loss affects colour vision (CV) testing. Eleven participants were scored while cycling through randomly arranged pictures of CV tests with varying levels of contrast changes applied. Hardy-Rand-Rittler (HRR) scores declined significantly at each successive decrease in contrast level after the highest setting
