Analyses of Pellets Produced from Spruce Sawdust, Spruce Bark, and Pine Cones in Different Proportions

open access: yesEnergies, 2022
A lot of residual biomass has energy value and can be used for further applications through suitable treatments, such as pelletization. This treatment can improve properties, mainly energy density, but can also lead to problems due to their low ash ...

Structural and Functional Characteristics of Color Vision Changes in Choroideremia

open access: yesFrontiers in Neuroscience, 2021
Color vision is considered a marker of cone function and its assessment in patients with retinal pathology is complementary to the assessments of spatial vision [best-corrected visual acuity (BCVA)] and contrast detection (perimetry).

A Novel ARL3 Gene Mutation Associated With Autosomal Dominant Retinal Degeneration

open access: yesFrontiers in Cell and Developmental Biology, 2021
Despite major progress in the discovery of causative genes, many individuals and families with inherited retinal degenerations (IRDs) remain without a molecular diagnosis.

Retinoic acid signaling mediates peripheral cone photoreceptor survival in a mouse model of retina degeneration

open access: yeseLife, 2022
Retinitis Pigmentosa (RP) is a progressive, debilitating visual disorder caused by mutations in a diverse set of genes. In both humans with RP and mouse models of RP, rod photoreceptor dysfunction leads to loss of night vision, and is followed by ...

Age and Sex-Related Changes in Retinal Function in the Vervet Monkey

open access: yesCells, 2022
Among the deficits in visual processing that accompany healthy aging, the earliest originate in the retina. Moreover, sex-related differences in retinal function have been increasingly recognized.
