Smartphone ophthalmoscopy: patient and student practitioner perceptions [PDF]

open access: yes, 2019
It can take several years to become proficient at direct ophthalmoscopy; the instrument’s single eyepiece allows only one individual to view the image at a time, which is considered disadvantageous during teaching.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

A Low-Dimensional Model of Coordinated Eye and Head Movements [PDF]

open access: yes, 1994
Eye and head movement data, were recorded under head fixed and head-free conditions, and compared with theoretical results obtained using a nonlinear model of eye-head coordination.

Urothelial bladder carcinoma metastasizing to the eye: a systematic review and case report [PDF]

open access: yes, 2019
The eye is a rare site for disseminated malignancies; nevertheless, several tumors may metastasize to ocular structures. Few cases of urothelial and bladder cancer with eye involvement have been described in the literature thus far.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

open access: yesFEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Fertilização In Vitro: Mais de 4 Milhões de Crianças Nascidas e Um Prêmio Nobel

open access: yesClinical and Biomedical Research, 2010
Em 1978, nasceu Louise Brown, o primeiro bebê de proveta. Este nascimento histórico foi o resultado de pesquisas do biólogo Robert Edwards e do ginecologista Patrick Steptoe (1).

Multigroup Comparisons with Configural Frequency Analysis

open access: yesJournal for Person-Oriented Research
Lienert’s (1973) original approach to comparing groups with Configural Frequency Analysis (CFA) cannot straightforwardly be generalized to the comparison of multiple groups.

Discovering Gender Differences in Facial Emotion Recognition via Implicit Behavioral Cues

open access: yes, 2017
We examine the utility of implicit behavioral cues in the form of EEG brain signals and eye movements for gender recognition (GR) and emotion recognition (ER). Specifically, the examined cues are acquired via low-cost, off-the-shelf sensors.

Independent and reciprocal accommodation in anisometropic amblyopia [PDF]

open access: yes, 2010
Accommodation is considered to be a symmetrical response and to be driven by the least ametropic and nonamblyopic eye in anisometropia. We report the case of a 4-year-old child with anisometropic amblyopia who accommodates asymmetrically, reliably ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
