Low-illumination Image Enhancement Algorithm Based on Visual Perception [PDF]
Jisuanji gongcheng, 2016 Aiming at the low brightness and low contrast of the low-illumination color image,an adaptive brightness enhancement algorithm based on visual perception is proposed by researching the automatic adjustment of the pupil and the photoreceptor cells to the ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

FEBS Open Bio, EarlyView.Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Classical dark adaptation in ERG responses.
, 2016 Normally reared rats were put into a dark environment, and scotopic ERGs response to a 50 ms flash (-1.14log cd*s/m2) were recorded within the initial 50 minutes dark adaptation. (A) ERGs across time from one rat.

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Screening and epitope characterization of Nidogen‐2‐specific nanobodies
FEBS Open Bio, EarlyView.Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

EFFECT OF MELANOPHORE-STIMULATING HORMONE ON HUMAN DARK ADAPTATION
, 1959 A preparation of melanophore-stimulating hormone (MSH) obtained from porcine anterior pituitary glands was found to produce no effect on the course of dark adaptation in normal human subjects, when injected subcutaneously in doses of 185 or 550 I.U.A ...
