An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

ESTIMATING SAMPLING VARIANCE FROM THE CURRENT POPULATION SURVEY: A SYNTHETIC DESIGN APPROACH TO CORRECTING STANDARD ERRORS [PDF]

Essentially all empirical questions that are addressed with sample data require estimates of sampling variance. The econometrics and statistics literatures show that these estimates depend critically on the design of the sample.

Comparative study on the performance of sampling methods for Myriapoda (Diplopoda, Chilopoda, Symphyla) and Oniscidea from Buzău mountains

Travaux de l'Institut de Speologie Emile Racovitza
In this paper we focus on some edaphic macroinvertebrates, Oniscidea, Diplopoda, Chilopoda and Symphyla, and their activity-density in relation with a short-term sampling protocol and a series of environmental factors.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

FEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Projective Blue‐Noise Sampling

, 2016
We propose projective blue‐noise patterns that retain their blue‐noise characteristics when undergoing one or multiple projections onto lower dimensional subspaces.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Item Count Technique in Ranked Set Sampling

, 2021
In situations where the estimation of the proportion of sensitive variables relies on the observations of real measurements that are difficult to obtain, there is a need to combine indirect questioning techniques.

Health related surveys: sampling methods

New Zealand Medical Student Journal
Have you ever thought of running a survey? You could run an online survey! Word on the street is that they’re easy to do. We wish that were true! Surveys can be very tricky and there can be a lot of hidden hooks for the unwary.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
