Long wavelength-sensing cones of zebrafish retina exhibit multiple layers of transcriptional heterogeneity

Frontiers in Cellular Neuroscience, 2023
IntroductionUnderstanding how photoreceptor genes are regulated is important for investigating retinal development and disease. While much is known about gene regulation in cones, the mechanism by which tandemly-replicated opsins, such as human long ...

Integration in Cones

Logical Methods in Computer Science
Measurable cones, with linear and measurable functions as morphisms, are a model of intuitionistic linear logic and of call-by-name probabilistic PCF which accommodates "continuous data types" such as the real line. So far however, they lacked a major feature to make them a model of more general probabilistic programming languages ...

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

FEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Positive solutions of higher order fractional integral boundary value problem with a parameter

Nonlinear Analysis, 2019
In this paper, we study a higher-order fractional differential equation with integral boundary conditions and a parameter. Under different conditions of nonlinearity, existence and nonexistence results for positive solutions are derived in terms of ...

Cone and rod function in cone degenerations

Vision Research, 1997
Progressive cone dystrophy (CD) is usually marked in the initial stages by reduced visual acuity, color vision deficiency and alterations in the photopic electroretinogram, while morphological alterations can be very mild; in some forms rods are affected in a later stage as well.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

FEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Periodic boundary value problems for first order difference equations

Electronic Journal of Qualitative Theory of Differential Equations, 2012
In this paper, existence criteria for single and multiple positive solutions of some of periodic boundary value problems for first order difference equation \[\left\{\begin{array}{ll} \Delta x(k)+f(k,x(k+1))=0, & k\in \left[ 0,T\right] ,\\ x(0)=x(T+1), &

III.—Notes on “Cone-In-Cone” Structure [PDF]

Geological Magazine, 1887
In Decade III. Vol. II. of the GEOLOGICAL MAGAZINE, for 1885, at page 283, an abstract of a paper on “ Cone-in-Cone ” by Mr. John Young, F.G.S., of Glasgow, was given. The author of this interesting paper has kindly presented the writer with a copy of it, to which, since it was readinGlasgow last year, has been added some additional remarks, together ...
