A two-step method for identifying photopigment opsin and rhodopsin gene sequences underlying human color vision phenotypes. [PDF]

open access: yes, 2020
PurposeTo present a detailed, reliable long range-PCR and sequencing (LR-PCR-Seq) procedure to identify human opsin gene sequences for variations in the long wavelength-sensitive (OPN1LW), medium wavelength-sensitive (OPN1MW), short wavelength-sensitive (

Cue-target contingencies modulate voluntary orienting of spatial attention: dissociable effects for speed and accuracy [PDF]

open access: yes, 2016
Voluntary orienting of spatial attention is typically investigated by visually presented directional cues, which are called predictive when they indicate where the target is more likely to appear. In this study we investigated the nature of the potential

Spectral light sensitivity and anomalous quotient in anomalous trichromats with protanomaly and deutanomaly

open access: yesJournal of Ophthalmology, 2017
Background. An ability to precisely distinguish red and green colors is crucial for many professions, which has conditioned the importance of color vision diagnostics and its application in vocational selection. Purpose: to determine the acuity of color

Face-gender discrimination is possible in the near-absence of attention [PDF]

open access: yes, 2004
The attentional cost associated with the visual discrimination of the gender of a face was investigated. Participants performed a face-gender discrimination task either alone (single-task) or concurrently (dual-task) with a known attentional demanding ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Visual scanning patterns and executive function in relation to facial emotion recognition in aging [PDF]

open access: yes, 2013
OBJECTIVE: The ability to perceive facial emotion varies with age. Relative to younger adults (YA), older adults (OA) are less accurate at identifying fear, anger, and sadness, and more accurate at identifying disgust.

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

open access: yesMolecular Oncology, EarlyView.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...
