Carotenoid Biosynthesis in Fusarium
Journal of Fungi, 2017 Many fungi of the genus Fusarium stand out for the complexity of their secondary metabolism. Individual species may differ in their metabolic capacities, but they usually share the ability to synthesize carotenoids, a family of hydrophobic terpenoid ...

Automatic Segmentation of Retinal Vasculature [PDF]
IEEE International Conference on Acoustics Speech and Signal
Processing (ICASSP), page: 886-890, 2017, 2017 Segmentation of retinal vessels from retinal fundus images is the key step in the automatic retinal image analysis. In this paper, we propose a new unsupervised automatic method to segment the retinal vessels from retinal fundus images. Contrast enhancement and illumination correction are carried out through a series of image processing steps followed ...

Photoreceptor Outer Segment-like Structures in Long-Term 3D Retinas from Human Pluripotent Stem Cells. [PDF]
, 2017 The retinal degenerative diseases, which together constitute a leading cause of hereditary blindness worldwide, are largely untreatable. Development of reliable methods to culture complex retinal tissues from human pluripotent stem cells (hPSCs) could ...

Use of ocular biomarkers as a potential tool for early diagnosis of Alzheimer's disease
Indian Journal of Ophthalmology, 2020 Alzheimer's disease (AD) is the most common neurodegenerative disease worldwide which unfortunately has no known effective cure to date. Despite many clinical trials indicating the effectiveness of preclinical treatment, a sensitive tool for screening of

A novel approach for glaucoma classification by wavelet neural networks using graph-based, statisitcal features of qualitatively improved images [PDF]
arXiv, 2022 In this paper, we have proposed a new glaucoma classification approach that employs a wavelet neural network (WNN) on optimally enhanced retinal images features. To avoid tedious and error prone manual analysis of retinal images by ophthalmologists, computer aided diagnosis (CAD) substantially aids in robust diagnosis.

The effects of growth factors on multicellular spheroids formed by chick embryonic retinal cells [PDF]
, 1997 Retinal cells from chick embryos aged 7.5 days of gestation were cultured for two months in a non-adherent suspension culture dish to study the effects of growth factors and co-culture with retinal pigment epithelial cells on their differentiation ...
