A Tunable Self-Offloading Module for Plantar Pressure Regulation in Diabetic Patients

Yves Perriard, Yoan René Cyrille Civet, Paolo Germano, Christian Köchli, Sofia Lydia Ntella, Kenny Jeanmonod, Bhawnath Tiwari

Plantar pressure plays a crucial role in the pathogenesis of foot ulcers among patients with diabetes and peripheral polyneuropathy. Pressure relief is a key requirement for both the prevention and treatment of plantar ulcers. Conventional medical practice ...

First Advanced Bilayer Scaffolds for Tailored Skin Tissue Engineering Produced via Electrospinning and Melt Electrowriting

Biranche Tandon, Nicolas Tissot

In vitro skin models are validated methods for screening cosmetics and pharmaceuticals, but still have limitations. The bilayer poly(epsilon-caprolactone) scaffold/membrane model described here overcomes some of these deficits by integrating a solution ele ...

Modeling of solids particle diversion to promote uniform growth of multiple hydraulic fractures

Guanyi Lu

Solid particulate additives are sometimes used to promote the uniform growth of multiple hydraulic fractures in horizontal oil and gas wells. The principle is that solid particulates block, accumulate, and form larger porous plugging zones preferentially a ...

Advances in the Sensing and Treatment of Wound Biofilms

Hubert Girault, Sorour Darvishi

Wound biofilms represent a particularly challenging problem in modern medicine. They are increasingly antibiotic resistant and can prevent the healing of chronic wounds. However, current treatment and diagnostic options are hampered by the complexity of th ...

Longitudinal interrogation of sympathetic neural circuits and hemodynamics in preclinical models

Grégoire Courtine, Quentin Barraud, Jordan Squair, Matthieu Pierre Gautier, Victor Perez Puchalt, Loïs Thomas Romain Mahe, Rémi Bernard René Hudelle, Jan Elaine Cuevas Soriano, Suje Amir

Neurological disorders, including spinal cord injury, result in hemodynamic instability due to the disruption of supraspinal projections to the sympathetic circuits located in the spinal cord. We recently developed a preclinical model that allows the ident ...

Revealing Antibiotic Tolerance of the Mycobacterium smegmatis Xanthine/Uracil Permease Mutant Using Microfluidics and Single-Cell Analysis

John McKinney, Neeraj Dhar, Meltem Elitas

To reveal rare phenotypes in bacterial populations, conventional microbiology tools should be advanced to generate rapid, quantitative, accurate, and high-throughput data. The main drawbacks of widely used traditional methods for antibiotic studies include ...

Modeling of Simultaneous Propagation of Multiple Blade‑Like Hydraulic Fractures from a Horizontal Well

Brice Tanguy Alphonse Lecampion, Dmitry Nikolskiy

We explore different aspects of the multi-stage fracturing process such as stress interaction between growing hydraulic fractures, perforation friction, as well as the wellbore flow dynamics using a specifically developed numerical solver. In particular, g ...

Vascular-targeted low dose photodynamic therapy stabilizes tumor vessels by modulating pericyte contractility

Paul Joseph Dyson, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, Tina Riedel

Vascular-targeted low-dose photodynamic therapy (L-PDT) was shown to improve chemotherapy distribution in malignant pleural tumors such as malignant pleural mesothelioma (MPM). However, the mechanisms triggered by L-PDT on the tumor vasculature are still d ...

Local induction of lymphangiogenesis with engineered fibrin-binding VEGF-C promotes wound healing by increasing immune cell trafficking and matrix remodeling

Jeffrey Alan Hubbell, Melody Swartz, Witold Waldemar Kilarski, Priscilla Suhasna Maithili Briquez, Esra Güç, Manuel Andreas Fankhauser

Lymphangiogenesis occurs in inflammation and wound healing, yet its functional roles in these processes are not fully understood. Consequently, clinically relevant strategies for therapeutic lymphangiogenesis remain underdeveloped, particularly using growt ...

Experiments versus theory for the initiation and propagation of radial hydraulic fractures in low permeability materials

Brice Tanguy Alphonse Lecampion

We compare numerical predictions of the initiation and propagation of radial fluid-driven fractures with laboratory experiments performed in different low permeability materials (PMMA, cement). In particular, we choose experiments where the time evolution ...

Remote Control of Intestinal Stem Cell Activity by Haemocytes in Drosophila

Bruno Lemaitre, Jean Philippe Boquete, Jan Paul Dudzic, Sveta Chakrabarti, Xiaoxue Li, Esther Jeanne Collas

The JAK/STAT pathway is a key signaling pathway in the regulation of development and immunity in metazoans. In contrast to the multiple combinatorial JAK/STAT pathways in mammals, only one canonical JAK/STAT pathway exists in Drosophila. It is activated by ...

Neuroprosthetic technologies to augment the impact of neurorehabilitation after spinal cord injury

Silvestro Micera, Grégoire Courtine, Jocelyne Bloch, Eduardo Martin Moraud, Joachim von Zitzewitz, Nicolas Francis Fumeaux, Marco Capogrosso, Rubia van den Brand, Fabien Bertrand Paul Wagner, Jean-Baptiste Mignardot

Spinal cord injury leads to a range of disabilities, including limitations in locomotor activity, that seriously diminish the patients’ autonomy and quality of life. Electrochemical neuromodulation therapies, robot-assisted rehabilitation and willpower-bas ...

Patient-specific mean pressure drop in the systemic arterial tree, a comparison between 1-D and 3-D models

Nikolaos Stergiopoulos, Philippe Reymond, François Lazeyras

One-dimensional models of the systemic arterial tree are useful tools for studying wave propagation phenomena, however, their formulation for frictional losses is approximate and often based on solutions for developed flow in straight non-tapered arterial ...

Engineering of Signaling Microenvironments with Fibronectin Domains to Enhance Tissue Regeneration

Mikaël Martino

Conducting tissue healing and regeneration through biomaterials and morphogens is still an unrealized goal. Understand the multiple roles of the extracellular matrix (ECM) is indeed essential for the design of successful regenerative medicine strategies. D ...

Extracellular matrix in angiogenesis: dynamic structures with translational potential

Jeffrey Alan Hubbell

The vascular network is an integral component of most organs. Beyond assuring an adequate supply of oxygen and nutrients for normal tissue function, vascular structures provide also a critical interface in the balance of tissue homoeostasis and immune func ...

Two-Phase Pressure Drops in Adiabatic Horizontal Circular Smooth U-Bends and Contiguous Straight Pipes (RP-1444)

John Richard Thome, Ricardo Lima

Curved channels in the form of bends are encountered in many industrial two-phase flow applications, such as U-bends in air-conditioning and refrigeration evaporators and condensers. For engineering design purposes, the evaluation of the pressure loss in t ...

Individualization of transfer function in estimation of central aortic pressure from the peripheral pulse is not required in patients at rest

Nikolaos Stergiopoulos, Nico Westerhof

Central aortic pressure gives better insight into ventriculo-arterial coupling and better prognosis of cardiovascular complications than peripheral pressures. Therefore transfer functions (TF), reconstructing aortic pressure from peripheral pressures, are ...
