Two Robust Tools for Inference about Causal Effects with Invalid Instruments [PDF]
Instrumental variables have been widely used to estimate the causal effect of a treatment on an outcome. Existing confidence intervals for causal effects based on instrumental variables assume that all of the putative instrumental variables are valid; a valid instrumental variable is a variable that affects the outcome only by affecting the treatment ...

Here, for the first time, macrophages and foam cells' adhesions to the developed polystyrene/graphene oxide‐3‐aminopropyltriethoxysilane/Anti‐CD36 (PS@GAPTES@Ab‐CD36) electrospun nanofiber‐based biofunctional surface using electrochemical measurements and fluorescence imaging are examined.

A Latent Mixture Model for Heterogeneous Causal Mechanisms in Mendelian Randomization [PDF]
Mendelian Randomization (MR) is a popular method in epidemiology and genetics that uses genetic variation as instrumental variables for causal inference. Existing MR methods usually assume most genetic variants are valid instrumental variables that identify a common causal effect.

Adjusting Cell‐Surface Interactions Through a Covalent Immobilization of Biomolecules
This review presents an overview of current and emerging immobilization techniques coupled with an in‐depth investigation of the underlying mechanisms governing the activity and stability of covalently immobilized biomolecules. The aim of this study is to serve as a guide for the development of long‐lasting biomedical coatings with versatile biological

Interaction of serum lipoproteins with the hydroperoxide of methyl linoleate*
The interaction of serum lipoproteins with the hydroperoxide of methyl linoleate was studied by means of analytical ultracentrifugal or paper electrophoretic analysis.

Regression with a right-censored predictor, using inverse probability weighting methods [PDF]
In a longitudinal study, measures of key variables might be incomplete or partially recorded due to drop-out, loss to follow-up, or early termination of the study occurring before the advent of the event of interest. In this paper, we focus primarily on the implementation of a regression model with a randomly censored predictor.

This work introduces a versatile and straightforward approach for directly fabricating electrospun 3D nanofibrous sponge using a selection of solvents, avoiding potentially toxic additives or additional steps. The most important novelty in this study is a one‐step electrospinning process that simultaneously imparts three‐dimensionality and ...

Correlative super‐resolution optical imaging of the ultrastructure of rat liver sinusoidal endothelial cells (LSECs) across a large field of view (FOV) with 3D structured illumination microscopy (3D‐SIM) and single‐molecule localization microscopy (SMLM), facilitated by a transparent polymer photonic waveguide chip, is presented.

Large lipoproteins are excluded from the arterial wall in diabetic cholesterol-fed rabbits
In diabetic hypercholesterolemic rabbits at plasma triglyceride concentrations of approximately 5000 mg/dl, 55% of plasma cholesterol (1400 mg/dl) was in lipoproteins with diameters larger than 75 nm (Sf greater than 400), 40% in smaller very low density
