A novel detrimental homozygous mutation in the WFS1 gene in two sisters from nonconsanguineous parents with untreated diabetes insipidus [PDF]

open access: yes, 2019
Given the limited lifespan and with the recent progress in experimental treatments for WS, timely diagnosis and multidisciplinary treatment for DI/DM, hydronephrosis, and visual/psychiatric status-maintaining quality of life-are of crucial ...

Consensual Pupillometry for robotic emotional recognition [PDF]

open access: yes, 2015
The main contribution of this research is to develop of a new measuring device for measuring direct- and consensual light reflex of human pupil. In this case the pupillary light reflex means changing of diameter of pupil due to constant light stimulus as

Estimation of operators’ fatigue using optical methods for determination of pupil activity

open access: yesInternational Journal of Occupational Medicine and Environmental Health, 2015
Introduction The purpose of this study was to develop and initially validate an objective, yet quick, method for assessment of human fatigue. This aim can be achieved by the use of an optical, non-contact method of analysis of pupil activity.

Regulatory effects of blood constituents on the function and metabolism of the cat brain in perfusion ezperiments. Brain perfusion with artificial blood containing low molecular dextran and amino acids [PDF]

open access: yes, 1967
As a link in a series of studies on the effects of blood constituents on the brain function by means of brain perfusion, we used four kinds of artificial blood; namely, the blood containing a low molecular dextran, one containing glutamic acid, one ...

Pupillary responses to single and sinusoidal light stimuli in diabetic patients

open access: yesNeurology International, 2009
We examined effects of diabetes mellitus (DM) on the pupillary light reflex (PLR). Phasic pupillary response to a single light stimulus (200 ms) (pPLR) and to continuous sinusoidal stimuli with four different frequencies (0.1, 0.3, 0.7, 1.3Hz) (cPLR ...

Pupillary behavior in relation to wavelength and age [PDF]

open access: yes, 2014
Pupil light reflex can be used as a non-invasive ocular predictor of cephalic autonomic nervous system integrity. Spectral sensitivity of the pupil´s response to light has, for some time, been an interesting issue.
