From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

open access: yesFEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Occipital proton magnetic resonance spectroscopy (1H-MRS) reveals normal metabolite concentrations in retinal visual field defects. [PDF]

open access: yesPLoS ONE, 2007
BACKGROUND: Progressive visual field defects, such as age-related macular degeneration and glaucoma, prevent normal stimulation of visual cortex. We investigated whether in the case of visual field defects, concentrations of metabolites such as N ...

Contralesional Trunk Rotation Dissociates Real vs. Pseudo-Visual Field Defects due to Visual Neglect in Stroke Patients

open access: yes, 2017
In stroke patients, the clinical presentation of visual field defects (VFDs) is frequently accompanied by visual neglect, i.e., the inability to attend and respond to the contralesional space.

Posterior Cortical Atrophy in the Asia‐Pacific: A Report From the PCA Asian Workgroup

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Posterior Cortical Atrophy (PCA) is a distinct dementia syndrome primarily affecting spatial abilities and visual processing. It is associated with degeneration in the posterior part of the brain. PCA is subclassified into PCA‐pure and PCA‐plus syndromes based on consensus criteria.

Case Series Study of Visual Field Defects in Pituitary Gland Tumors [PDF]

open access: yesAl Ameen Journal of Medical Sciences, 2017
Background: The pituitary gland is a small endocrine gland, weighing about 500 mg. Pituitary adenomas account for 12-15 % of all intracranial tumors. Pituitary gland is in the sella turcica, 8-13 mm lower than the optic chiasm.

Compensatory recovery after multisensory stimulation in hemianopic patients: behavioral and neurophysiological components

open access: yesFrontiers in Systems Neuroscience, 2016
Lateralized post-chiasmatic lesions of the primary visual pathway result in loss of visual perception in the field retinotopically corresponding to the damaged cortical area.

Customized, automated stimulus location choice for assessment of visual field defects.

open access: yesInvestigative Ophthalmology and Visual Science, 2014
PURPOSE To introduce a perimetric algorithm (gradient-oriented automated natural neighbor approach [GOANNA]) that automatically chooses spatial test locations to improve characterization of visual field (VF) loss without increasing test times.

Visual Field Defects in Chiasmal Lesions

open access: yes, 2021
Classic teaching states that compression of the optic chiasm impacts decussating nasal retinal axons producing a bitemporal hemianopia (BTH). In fact, visual field defects resulting from chiasmal lesions are quite variable1.

Eye movement behaviour of patients with visual field defects [PDF]

open access: yes, 2021
People with a visual field defect suffer from reduced sensitivity or even complete blindness in parts of the visual field. Two common causes of visual field defects are glaucoma: a neurodegenerative disease in which peripheral vision slowly declines due ...
