Determinants of undergraduate bioscience engagement: Validating attendance barriers and classroom spatial behaviour across institutions

open access: yesFEBS Open Bio, EarlyView.
Student engagement extends beyond simple attendance. Across 891 bioscience students from three universities, attendance behaviour was associated mainly with structural influences, whereas classroom spatial behaviour reflected affective and sensory factors.

Factors Affecting Contrast Sensitivity in Healthy Individuals: A Pilot Study

open access: yes, 2017
Objectives: To determine the demographic and ocular features affecting contrast sensitivity levels in healthy individuals. Materials and Methods: Seventy-four eyes of 37 subjects (7-65 years old) with refractive errors less than 1.0 diopter, no history ...

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Higher-harmonic adaptation and the detection of squarewave gratings [PDF]

open access: yes, 1987
Adaptation to a high contrast sinewave grating of 1 c/deg spatial frequency causes a large increase in the contrast threshold for a 1 c/deg test grating, but fails to raise the threshold for a squarewave grating of 0.33 c/deg, although the sensitivity of

Learning-induced sensory plasticity of mouse olfactory epithelium

open access: yesВавиловский журнал генетики и селекции, 2019
Traditionally, studies of the neurobiology of learning and memory focus on the circuitry that interfaces between sensory inputs and behavioral outputs, such as the amygdala and cerebellum. However, evidence is accumulating that some forms of learning can

Measuring the Luminance Contrast Sensitivity Function in Peripheral Vision

open access: yesColor Research & Application
ABSTRACT We measured luminance contrast sensitivity functions (CSF) of four subjects by using Gabor stimuli up to 56°, 49°, 84°, and 63° in the nasal, superior, temporal, and inferior directions, respectively, of the left‐eye visual field.

Understanding Further the Phenotypic Spectrum of Central Nervous System Inflammatory Demyelinating Disorders Using Unsupervised Clustering

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Central nervous system (CNS) inflammatory demyelinating syndromes, including multiple sclerosis (MS), aquaporin‐4 antibody–positive neuromyelitis optica spectrum disorder (AQP4 + NMOSD), and myelin oligodendrocyte glycoprotein (MOG) antibody–associated disease (MOGAD), occasionally overlap.

Luminance and contrast adaptation of the inner retina [PDF]

open access: yes, 2015
Adaptation is a common feature of sensory systems, matching neural activity to the range of inputs from the environment. In the visual system this is of great importance because visual stimulus can change across 9 orders of magnitude.

Ofatumumab in Myelin Oligodendrocyte Glycoprotein Antibody–Associated Disease: A Comparison With Rituximab

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate the efficacy and safety of ofatumumab in patients with myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), and compare it with rituximab. Methods We conducted a single–center, observational study including 22 MOGAD patients treated with ofatumumab and 21 treated with rituximab.

Glucose availability and sensitivity to anoxia of isolated rat peripheral nerve [PDF]

open access: yes, 1991
The contrast between resistance to ischemia and ischemic lesions in peripheral nerves of diabetic patients was explored by in vitro experiments. Isolated and desheathed rat peroneal nerves were incubated in the following solutions with different glucose ...
