VISUAL OUTCOMES OF IMPLANTATION OF MULTIFOCAL INTRAOCULAR LENS WITH ASYMMETRICAL LIGHT DISTRIBUTION

open access: yesAlʹmanah Kliničeskoj Mediciny, 2016
Background: The results of implantation of refractive intraocular lenses (IOL), especially with an inferior segmental near add are of great interest due to advantages of the new lenses over more frequently used diffractive multifocal IOL.

Initial Findings on Visual Acuity Thresholds in an African Elephant (\u3cem\u3eLoxodonta africana\u3c/em\u3e) [PDF]

open access: yes, 2010
There are only a few published examinations of elephant visual acuity. All involved Asian elephants (Elephas maximus) and found visual acuity to be between 8′ and 11′ of arc for a stimulus near the tip of the trunk, equivalent to a 0.50 cm gap, at a ...

The effect of visual impairment on quality of life of children aged 3-16 years [PDF]

open access: yes, 2010
Background: It is well known that visual impairment (VI) has a detrimental effect on Quality of Life (QoL) in adults. Little is known about the effects of VI in childhood. Aims: To evaluate the effects of VI on QoL of children.

Bridging the gap: Multi‐stakeholder perspectives of molecular diagnostics in oncology

open access: yesMolecular Oncology, EarlyView.
Although molecular diagnostics is transforming cancer care, implementing novel technologies remains challenging. This study identifies unmet needs and technology requirements through a two‐step stakeholder involvement. Liquid biopsies for monitoring applications and predictive biomarker testing emerge as key unmet needs. Technology requirements vary by

Investigating the cell of origin and novel molecular targets in Merkel cell carcinoma: a historic misnomer

open access: yesMolecular Oncology, EarlyView.
This study indicates that Merkel cell carcinoma (MCC) does not originate from Merkel cells, and identifies gene, protein & cellular expression of immune‐linked and neuroendocrine markers in primary and metastatic Merkel cell carcinoma (MCC) tumor samples, linked to Merkel cell polyomavirus (MCPyV) status, with enrichment of B‐cell and other immune cell

Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids

open access: yesMolecular Oncology, EarlyView.
This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.

Visual acuity in larval zebrafish: behavior and histology [PDF]

open access: yes, 2010
BACKGROUND: Visual acuity, the ability of the visual system to distinguish two separate objects at a given angular distance, is influenced by the optical and neuronal properties of the visual system.
