Platelets and Lipoproteins

open access: yesPlatelets, 1994
Sir, Malle and Sattler's excellent review links lipids with the release of serotonin from platelets.' It is therefore, of interest that correlations between serum cholesterol and intraplatelet/plasma serotonin concentrations have been reported.'-* Moreover, reducing serum cholesterol and low density lipoprotein (LDL) concentrations normalised ...

Nanotherapy for Neural Retinal Regeneration

open access: yesAdvanced Science, EarlyView.
Nanotechnology enhances ophthalmic treatments by improving drug delivery and regenerating ocular tissues, combating vision loss from retinal diseases through innovative nano‐systems. This review outlines ocular anatomy, pathology, immune microenvironment, and barriers, detailing nanocarrier characteristics, classification, and preparation methods, and ...

Affinity‐Based Isolation and One‐Pot Analysis of Extracellular Vesicles from Biofluids Using Phase Separated Zwitterionic Coacervates

open access: yesAdvanced 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.

Activation of lipoprotein lipase by lipoprotein fractions of human serum

open access: yesJournal of Lipid Research, 1970
Triglycerides in fat emulsions are hydrolyzed by lipoprotein lipase only when they are “activated” by serum lipoproteins. The contribution of different lipoprotein fractions to hydrolysis of triglycerides in soybean oil emulsion was assessed by ...

Two Robust Tools for Inference about Causal Effects with Invalid Instruments [PDF]

open access: yesarXiv, 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 ...

Coordinated Role of Autophagy and ERAD in Maintaining Neuroendocrine Function by Preventing Prohormone Aggregation

open access: yesAdvanced Science, EarlyView.
By studying the maturation mechanisms of vasopressin (AVP), this manuscript identifies FAM134B‐mediated ER‐phagy as a critical pathway for degrading both aggregated proAVP and the key ERAD component, HRD1. HRD1 induction mitigates proAVP aggregation and support AVP neuron function in the absence of autophagy.

Rapid method for the isolation of lipoproteins from human serum by precipitation with polyanions

open access: yesJournal of Lipid Research, 1970
Procedures are described for the isolation of lipoproteins from human serum by precipitation with polyanions and divalent cations. A mixture of low and very low density lipoproteins can be prepared without ultracentrifugation by precipitation with ...

A Latent Mixture Model for Heterogeneous Causal Mechanisms in Mendelian Randomization [PDF]

open access: yesarXiv, 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.

Macrophage HM13/SPP Enhances Foamy Macrophage Formation and Atherogenesis

open access: yesAdvanced 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 ...

Regression with a right-censored predictor, using inverse probability weighting methods [PDF]

open access: yesarXiv, 2020
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.
