Effects of thermal, mechanical, and electrostatic perturbations on lipid membrane hydration investigated by second harmonic imaging

Hydrated lipid bilayer membranes are crucial components of cells and organelles, serving as the outer boundary that separates the cellular components from the extracellular environment. Lipid membranes regulate their structures and functions by dynamically ...

Self-organized patterning of cell morphology via mechanosensitive feedback

Marko Popovic

Tissue organization is often characterized by specific patterns of cell morphology. How such patterns emerge in developing tissues is a fundamental open question. Here, we investigate the emergence of tissue-scale patterns of cell shape and mechanical tiss ...

Loss of Bacterial Cell Pole Stabilization in Caulobacter crescentus Sensitizes to Outer Membrane Stress and Peptidoglycan-Directed Antibiotics

Gerardo Turcatti, Marc Chambon, Julien Bortoli Chapalay

Rod-shaped bacteria frequently localize proteins to one or both cellpoles in order to regulate processes such as chromosome replication or polar organ-elle development. However, the roles of polar factors in responses to extracellularstimuli have been gene ...

Triboelectric effect to harness fluid flow energy

Danick Briand, Rubaiyet Iftekharul Haque, Amr Yehia Hussien Mahmoud Arafat

We are reporting energy scavenging from fluid flows inside tubular structures using triboelectric effects. Two separate designs of triboelectric generators are proposed. A tubular design that uses liquid-solid interaction mechanism for water, and freestand ...

Mechanisms protecting host cells against bacterial pore-forming toxins

Francisco De Magalhães Sarmento R De Mesquita

Pore-forming toxins (PFTs) are key virulence determinants produced and secreted by a variety of human bacterial pathogens. They disrupt the plasma membrane (PM) by generating stable protein pores, which allow uncontrolled exchanges between the extracellula ...

Measurement of absolute cell volume, osmotic membrane water permeability, and refractive index of transmembrane water and solute flux by digital holographic microscopy

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Pascal Jourdain, Daniel Boss

A dual-wavelength digital holographic microscope to measure absolute volume of living cells is proposed. The optical setup allows us to reconstruct two quantitative phase contrast images at two different wavelengths from a single hologram acquisition. When ...

Interplay between cytoskeletal forces, membrane tension and shape in rapidly migrating cells

Chiara Gabella

Cell migration is a fundamental process in all animal cells. The ability of cell to migrate is crucial for many pathological and physiological conditions such as morphogenesis, the immune response to inflammatory or vascular diseases and cancer metastasis. ...

Studies on scaffold design for tissue engineering applications

The aim of tissue engineering is to regenerate tissue for the purpose of repairing or replacing diseased or injured tissue. Therefore, cells that are able to proliferate are seeded on scaffolds that provide mechanical stability and direct the three-dimensi ...
