Retinal pigment epithelium degeneration caused by aggregation of PRPF31 and the role of HSP70 family of proteins [PDF]
, 2020 Background Mutations in pre-mRNA splicing factor PRPF31 can lead to retinitis pigmentosa (RP). Although the exact disease mechanism remains unknown, it has been hypothesized that haploinsufficiency might be involved in the ...

Amino acids in retinitis pigmentosa
Indian Journal of Ophthalmology, 1988 Retinitis pigmentosa may be associated with amino acid′ disorders; whether the association is incidental or consequential is not known. The present investigation on amino acids in retinitis pigmentosa indicates that the level of plasma amino acids

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 ...

Human asthenozoospermia: Update on genetic causes, patient management, and clinical strategies
Andrology, EarlyView.Abstract Background In mammals, sperm fertilization potential relies on efficient progression within the female genital tract to reach and fertilize the oocyte. This fundamental property is supported by the flagellum, an evolutionarily conserved organelle, which contains dynein motor proteins that provide the mechanical force for sperm propulsion and ...

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.

Andrology, EarlyView.Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.

RPGR protein complex regulates proteasome activity and mediates store-operated calcium entry [PDF]
, 2018 Ciliopathies are a group of genetically heterogeneous disorders, characterized by defects in cilia genesis or maintenance. Mutations in the RPGR gene and its interacting partners, RPGRIP1 and RPGRIP1L, cause ciliopathies, but the function of their ...
