Optimizing Angiopep‐2 Density on Polymeric Nanoparticles for Enhanced Blood–Brain Barrier Penetration and Glioblastoma Targeting: Insights From In Vitro and In Vivo Experiments

Advanced Functional Materials, EarlyView.
The Angiopep‐2 peptide density on polymeric nanoparticles significantly impacts blood–brain barrier (BBB) penetration. This study explores this nuanced relationship using various in vitro models and in vivo assays, revealing that dynamic models better predict BBB penetration.

Stability of discoidal high-density lipoprotein particles [PDF]

arXiv, 2013
Motivated by experimental and numerical studies revealing that discoidal high-density lipoprotein (HDL) particles may adopt flat elliptical and nonplanar saddle-like configurations, it is hypothesized that these might represent stabilized configurations of initially unstable flat circular particles. A variational description is developed to explore the

“Therapies Through Gut:” Targeted Drug Delivery for Non‐Gastrointestinal Diseases by Oral Administration

Advanced Healthcare Materials, EarlyView.
Schematic illustration of the mechanism of targeted delivery of nanoparticles including 1) paracellular, 2) endolysosomal escape, 3) receptor mediated endocytosis, and 4) M cell mediated transport for non‐GI diseases by oral administration such as atherosclerosis, cancer, diabetes, and brain diseases. Abstract Oral drug delivery is a promising approach

Kruskal-Wallis Power Studies Utilizing Bernstein Distributions; preliminary empirical studies using simulations/medical studies [PDF]

arXiv, 2021
Bernstein fits implemented into R allow another route for Kruskal-Wallis power-study tool development. Monte-Carlo Kruskal-Wallis power studies were compared with measured power, with Monte-Carlo ANOVA equivalent and with an analytical method, with or without normalization, using four simulated runs each with 60-100 populations (each population with N ...

Beyond HDL-cholesterol increase: phospholipid enrichment and shift from HDL3 to HDL2 in alcohol consumers

Journal of Lipid Research, 2007
The reduction of cardiovascular mortality associated with moderate alcohol consumption is chiefly thought to be mediated by an increase of high density lipoprotein cholesterol (HDL-CH).

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.

Biomimetic Scaffolds Enhance iPSC Astrocyte Progenitor Angiogenic, Immunomodulatory, and Neurotrophic Capacity in a Stiffness and Matrix‐Dependent Manner for Spinal Cord Repair Applications

Advanced Healthcare Materials, EarlyView.
Through tuning biomimetic scaffold stiffness and matrix composition the reparative capacity of astrocyte progenitors is enhanced. Soft, collagen‐IV/fibronectin‐functionalized scaffolds promote progenitor growth while improving angiogenic, immunomodulatory, and neurotrophic capacity in a stiffness and matrix‐dependent manner, demonstrating the impact of

LDL and HDL transfer rates across peripheral microvascular endothelium agree with those predicted for passive ultrafiltration in humans

Journal of Lipid Research, 2015
The mechanisms by which LDLs and HDLs cross the vascular endothelium from plasma into interstitial fluid are not understood, and have never been studied in humans in vivo.

Pathways-driven Sparse Regression Identifies Pathways and Genes Associated with High-density Lipoprotein Cholesterol in Two Asian Cohorts [PDF]

arXiv, 2013
Standard approaches to analysing data in genome-wide association studies (GWAS) ignore any potential functional relationships between genetic markers. In contrast gene pathways analysis uses prior information on functional structure within the genome to identify pathways associated with a trait of interest. In a second step, important single nucleotide
