Test of the 'glymphatic' hypothesis demonstrates diffusive and aquaporin-4-independent solute transport in rodent brain parenchyma

open access: yeseLife, 2017
Transport of solutes through brain involves diffusion and convection. The importance of convective flow in the subarachnoid and paravascular spaces has long been recognized; a recently proposed ‘glymphatic’ clearance mechanism additionally suggests that ...

Aqueous Angiography: Real-Time and Physiologic Aqueous Humor Outflow Imaging. [PDF]

open access: yesPLoS ONE, 2016
PURPOSE:Trabecular meshwork (TM) bypass surgeries attempt to enhance aqueous humor outflow (AHO) to lower intraocular pressure (IOP). While TM bypass results are promising, inconsistent success is seen.

Formation of Microcages from a Collagen Mimetic Peptide via Metal-Ligand Interactions

open access: yesMolecules, 2021
Here, the hierarchical assembly of a collagen mimetic peptide (CMP) displaying four bipyridine moieties is described. The CMP was capable of forming triple helices followed by self-assembly into disks and domes.

Specific modulation of airway epithelial tight junctions by apical application of an occludin peptide [PDF]

open access: yes, 2006
Tight junctions are directly involved in regulating the passage of ions and macromolecules (gate functions) in epithelial and endothelial cells. The modulation of these gate functions to transiently regulate the paracellular permeability of large solutes

PARP inhibitors elicit distinct transcriptional programs in homologous recombination competent castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
PARP inhibitors are used to treat a small subset of prostate cancer patients. These studies reveal that PARP1 activity and expression are different between European American and African American prostate cancer tissue samples. Additionally, different PARP inhibitors cause unique and overlapping transcriptional changes, notably, p53 pathway upregulation.

Identification of amino acids essential for angulin‐1/3 binding of the tricellular tight junction binder, angubindin‐1

open access: yesFEBS Open Bio, EarlyView.
Angubindin‐1 binds angulin‐1/‐3 at tricellular tight junctions, enhancing intestinal macromolecule permeation. Alanine scanning identified six essential residues (L562, L598, E638, V640, Y643, and K644) of angubindin‐1 critical for binding to angulin‐1/‐3 and permeation‐enhancing activity, providing insights for the development of targeted noninvasive ...

Transdermal delivery of FITC-Dextrans with different molecular weights using radiofrequency microporation

open access: yesBiomaterials Research, 2020
Background Transdermal delivery is of great importance for the effective delivery of bioactive or therapeutic agents into a body. The microporation device based on radiofrequency can be used to enhance delivery efficiency by removing the epidermis layer.

Dextrans in Aqueous Solution. Experimental Review on Intrinsic Viscosity Measurements and Temperature Effect [PDF]

open access: yes, 2014
The study of biopolymers as dextran in aqueous solution, is effectively determined by intrinsic viscosity [η] measurements at different temperatures. Molecular weight (Mv) and hydrodynamic properties can be calculated from there.
