Effects of Polymer 3D Architecture, Size, and Chemistry on Biological Transport and Drug Delivery In Vitro and in Orthotopic Triple Negative Breast Cancer Models

Advanced Healthcare Materials, 2020
The size, shape, and underlying chemistries of drug delivery particles are key parameters which govern their ultimate performance in vivo. Responsive particles are desirable for triggered drug delivery, achievable through architecture change and ...

Temporal evaluation of efficacy and quality of tissue repair upon laser‐activated sealing

Bioengineering & Translational Medicine, 2023
Injuries caused by surgical incisions or traumatic lacerations compromise the structural and functional integrity of skin. Immediate approximation and robust repair of skin are critical to minimize occurrences of dehiscence and infection that can lead to

Permeability of the Perindopril Arginine under In Vitro Conditions across Caco-2 Monolayer and Biomimetic Phospholipid Membrane

Molecules, 2022
Perindopril arginine (PA) as an angiotensin-converting enzyme (ACE) inhibitor is widely used in cardiovascular diseases, especially in systemic hypertension and heart failure. Although the pharmacokinetics of PA are well documented, there is no available

Oral drug delivery for immunoengineering

Bioengineering & Translational Medicine, 2022
The systemic pharmacotherapeutic efficacy of immunomodulatory drugs is heavily influenced by its route of administration. A few common routes for the systemic delivery of immunotherapeutics are intravenous, intraperitoneal, and intramuscular injections ...

Interfacial and Internal Proton Conduction of Weak-acid Functionalized Styrene-based Copolymer with Various Carboxylic Acid Concentrations

Electrochemistry, 2021
Investigation of interfacial proton transport is necessary to elucidate biological systems. As commonly found in biomaterials, the carboxylic acid group was proven to act as a proton-conducting group.

Biological Electron Transport Systems [PDF]

Proceedings of the National Academy of Sciences, 1970
The solid-state electrical conductivities of a number of ferredoxin model compounds are reported. For one of these compounds, (KFeS 2 ) n , an electron transfer rate for a 25 Å unit is shown to be at least 1 × 10 8 electrons sec -

A two-lane mechanism for selective biological ammonium transport

eLife, 2020
The transport of charged molecules across biological membranes faces the dual problem of accommodating charges in a highly hydrophobic environment while maintaining selective substrate translocation.

The Need for a Kinetics for Biological Transport

Biophysical Journal, 1973
The traditional theory of transport across capillary membranes via a laminar Poiseuille flow is shown to be invalid. It is demonstrated that the random, diffusive nature of the molecular flow and interactions with the "pore" walls play an important role in the transport process.

Non-equilibrium statistical mechanics: from a paradigmatic model to biological transport [PDF]

, 2011
Unlike equilibrium statistical mechanics, with its well-established foundations, a similar widely accepted framework for non-equilibrium statistical mechanics (NESM) remains elusive. Here, we review some of the many recent activities on NESM, focusing on
