Oxidative Stress in Aging Human Skin

Biomolecules, 2015
Oxidative stress in skin plays a major role in the aging process. This is true for intrinsic aging and even more for extrinsic aging. Although the results are quite different in dermis and epidermis, extrinsic aging is driven to a large extent by ...

Crosstalk between the Rod Outer Segments and Retinal Pigmented Epithelium in the Generation of Oxidative Stress in an In Vitro Model

Cells, 2023
Dysfunction of the retinal pigment epithelium (RPE) is associated with several diseases characterized by retinal degeneration, such as diabetic retinopathy (DR).

Retinal dystrophies simulating geographic atrophy: A diagnostic challenge

Acta Ophthalmologica, EarlyView.
Abstract Geographic atrophy (GA) is the chronic loss of retinal pigment epithelium, photoreceptors and choriocapillaris, marking the dry late stage of age‐related macular degeneration (AMD). GA prevalence is expected to rise in the upcoming decades. Advanced GA leads to central scotomas, reducing visual acuity and quality of life, potentially resulting

Regional growth kinetics of geographic atrophy in age‐related macular degeneration with and without fovea‐sparing

Acta Ophthalmologica, EarlyView.
Abstract Purpose Fovea‐sparing geographic atrophy (GA) patients retain near‐normal central vision. To better understand GA progression in relation to the fovea, we performed a semi‐automated image analysis of regional atrophy growth in a long‐term GA natural‐history cohort. Methods Prospective‐observational, single‐centre‐study (02/2013–07/2025) at the

Fundus autofluorescence applications in retinal imaging

Indian Journal of Ophthalmology, 2015
Fundus autofluorescence (FAF) is a relatively new imaging technique that can be used to study retinal diseases. It provides information on retinal metabolism and health. Several different pathologies can be detected.

Longevity and Growth of the Crabs Callinectes sapidus and Callinectes rathbunae (Decapoda: Portunidae) in Paraíso Tabasco Mexico

Acta Zoologica, EarlyView.
ABSTRACT Individual growth models are important in fisheries of natural populations and can be incorporated in production models to estimate their maximum sustainable yield. Blue crab species, Callinectes sapidus and Callinectes rathbunae were obtained in the Mecoacán lagoon, Paraíso, Tabasco Mexico by “nasa” and “yahual” nets. Biometric values such as

Macular edema in Asian Indian premature infants with retinopathy of prematurity: Impact on visual acuity and refractive status after 1-year

Indian Journal of Ophthalmology, 2015
Purpose: To report the impact of transient, self-resolving, untreated "macular edema" detected on spectral domain optical coherence tomography in Asian Indian premature infants with retinopathy of prematurity (ROP) on visual acuity (VA) and refraction at
