Two Robust Tools for Inference about Causal Effects with Invalid Instruments [PDF]
arXiv, 2020 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 ...

Advanced Science, EarlyView.This study presents a novel method for affinity‐based isolation and analysis of extracellular vesicles from biofluids using phase‐separated zwitterionic coacervates functionalized with a membrane‐sensing peptide. This technology minimizes nonspecific binding, enabling high‐yield isolation and direct one‐pot biomarker profiling.

Journal of Lipid Research, 2000 Foam cell formation occurs in vitro at lipoprotein concentrations above 50 μg/ml in pigeon macrophages. Hypothetically, intracellular trafficking of lipoproteins at higher concentrations may differ from uptake of lipoproteins associated with low ...

A Latent Mixture Model for Heterogeneous Causal Mechanisms in Mendelian Randomization [PDF]
arXiv, 2020 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.

Circulation, 2013 Background— Elevated nonfasting remnant cholesterol and low-density lipoprotein (LDL) cholesterol are causally associated with ischemic heart disease (IHD), but whether elevated nonfasting remnant cholesterol and LDL cholesterol both cause low-grade ...

hESCs‐derived Organoids Achieve Liver Zonation Features through LSEC Modulation
Advanced Science, EarlyView.This article addresses the absence of zonation features in current organoid models by co‐culturing human embryonic stem cell‐derived hepatocytes with liver sinusoidal endothelial cells exhibiting distinct zonal characteristics. It demonstrates that differential WNT2 signaling from endothelial cells modulates hepatocyte zonation and metabolic functions,

Journal of Lipid Research, 1989 The rate of degradation of oxidatively modified low density lipoprotein (Ox-LDL) by human endothelial cells was similar to that of unmodified low density lipoprotein (LDL), and was approximately 2-fold greater than the rate of degradation of acetylated ...

Structured functional regression models for high-dimensional spatial spectroscopy data [PDF]
arXiv, 2013 Modeling and analysis of spectroscopy data is an active area of research with applications to chemistry and biology. This paper focuses on analyzing Raman spectra obtained from a bone fracture healing experiment, although the functional regression model for predicting a scalar response from high-dimensional tensors can be applied to any spectroscopy ...

Macrophage HM13/SPP Enhances Foamy Macrophage Formation and Atherogenesis
Advanced Science, EarlyView.Previous research suggests that AIP may prevent atherogenic foamy macrophage formation. This study reveals that AIP, via its chaperone interaction with AHR, inhibits p38‐c‐JUN‐mediated transactivation of HM13, which encodes the ERAD protease HM13/SPP. HM13/SPP promotes foamy macrophage formation in addition to atherogenesis and plaque foamy macrophage ...
