Efficient Characterization and Classification of Contrast Sensitivity Functions in Aging
, 2017 The contrast sensitivity function (CSF), delineating contrast sensitivity over a wide range of spatial frequencies, provides a comprehensive characterization of spatial vision and a sensitive test for many physiological and pathological processes.

Contrast Sensitivity and Asthenopia Analysis in Workers
Acta Medica BulgaricaIn the digital age, complaints of eyestrain, or asthenopia, have become increasingly common. This condition is often associated with prolonged near-work activities, such as extended use of computers or digital devices, with reported prevalence rates ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

FEBS Letters, EarlyView.Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

The role of contrast sensitivity charts and contrast letter charts in clinical practice
, 1995 Practitioners frequently make clinical decisions based on changes in visual acuity. However, acuity is recognised to be only one aspect of visual performance.

Effect of astigmatism and spherical equivalent correction on contrast sensitivity [PDF]
International Journal of OphthalmologyAIM: To investigate the effect of astigmatism and spherical equivalent (SE) correction on contrast sensitivity (CS). METHODS: In this cross-sectional study, 103 visually normal subjects aged 18 to 36y with bilateral regular astigmatism in range of 1.00 ...

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
