DARK ADAPTATION IN DINEUTES [PDF]

open access: yesJournal of General Physiology, 1938
The level of dark adaptation of the whirligig beetle can be measured in terms of the threshold intensity calling forth a response. The course of dark adaptation was determined at levels of light adaptation of 6.5, 91.6, and 6100 foot-candles. All data can be fitted by the same curve.

In Situ Dark Adaptation Enhances the Efficiency of DNA Extraction from Mature Pin Oak (Quercus palustris) Leaves, Facilitating the Identification of Partial Sequences of the 18S rRNA and Isoprene Synthase (IspS) Genes

open access: yesPlants, 2017
Mature oak (Quercus spp.) leaves, although abundantly available during the plants’ developmental cycle, are rarely exploited as viable sources of genomic DNA.

PSYCHOPHYSICAL METHODS OF STUDY IN THE EVALUATION OF EFFICIENCY IN ADMINISTRATION OF ANTIOXIDANTS IN PRE- AND POST-OPERATIVE PERIOD OF CATARACT PHACOEMULSIFICATION

open access: yesОфтальмохирургия, 2017
Age-related macular degeneration (AMD) and senile cataract are associated with the age. The basic method of surgery in all types of cataracts is phacoemulsification.

Light-dependent changes in the outer plexiform layer of the mouse retina

open access: yesFrontiers in Ophthalmology, 2023
The ability of the visual system to relay meaningful information over a wide range of lighting conditions is critical to functional vision, and relies on mechanisms of adaptation within the retina that adjust sensitivity and gain as ambient light changes.

Shedding Light on the Effect of Fish Oil Supplementation on Dark Adaptation Capabilities

open access: yes, 2019
This is the first study to directly relate the uptake of fatty acids from fish oil supplements (as measured by blood analysis) to changes in dark adaptation capabilities.

Domain Adaptation for Simulation-based Dark Matter Searches with Strong Gravitational Lensing

open access: yesThe Astrophysical Journal, 2023
The identity of dark matter has remained surprisingly elusive. While terrestrial experiments may be able to nail down a model, an alternative method is to identify dark matter based on astrophysical or cosmological signatures.

The Impact of LED Light Color on the Dark Adaptation of Human Vision in Tunnel Entrances

open access: yesIEEE Photonics Journal, 2018
For the study of dark adaptation at the entrance section of a tunnel, the effects of photopigments in rod cells and luminance can be disregarded because the luminance of this section is in the range of photopic vision.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Comparison of Fine Structure of the Compound Eyes in Eucryptorrhynchus scrobiculatus and Eucryptorrhynchus brandti Adults

open access: yesInsects, 2023
Eucryptorrhynchus scrobiculatus and E. brandti are the main borers of Ailanthus altissima, causing serious economic and ecological losses. The external morphology and internal ultrastructure of the compound eyes of two related weevils were investigated ...
