Dynamics of membranes driven by actin polymerization [PDF]
, 2005 A motile cell, when stimulated, shows a dramatic increase in the activity of its membrane, manifested by the appearance of dynamic membrane structures such as lamellipodia, filopodia and membrane ruffles. The external stimulus turns on membrane bound activators, like Cdc42 and PIP2, which cause increased branching and polymerization of the actin ...

Transport of particles through RO membrane in steady state condition [PDF]
arXiv, 2023 Reverse Osmosis(RO) membranes are widespread nowadays for separating the solvent from a solution. RO membranes are made of polymer matrix. Experiments show changes in relative interaction of solvent and solute with RO membrane matrix lead to changes in solvent permeation, solute rejection and fouling.

Clinical &Experimental Ophthalmology, EarlyView.ABSTRACT Background In the last two decades, over 250 000 refugees and asylum seekers have arrived in Australia, many of whom experience significant health problems. Information about their eye health is scarce, particularly for those detained offshore. This is the first study to explore the eye health and services available to this population, helping

Glia, Volume 73, Issue 5, Page 905-927, May 2025.Main Points Ibudilast, a MIF and PDE inhibitor, preserves the form and function of the retina, especially bipolar cells, during excitotoxic damage. Ibudilast upregulates multiple signaling pathways, including mTOR, in damaged Müller glia and bipolar cells.

Laser driven miniature diamond implant for wireless retinal prostheses [PDF]
Advanced Biosystems 4.11 (2020): 2000055The design and benchtop operation of a wireless miniature epiretinal stimulator implant is reported. The implant is optically powered and controlled using safe illumination at near-infrared wavelengths. An application-specific integrated circuit (ASIC) hosting a digital control unit is used to control the implant's electrodes. The ASIC is powered using

Acta Ophthalmologica, Volume 103, Issue 3, Page e156-e164, May 2025.Abstract Purpose To compare vitrectomy with and without internal limiting membrane (ILM) peeling in small idiopathic macular holes. Methods Retrospective multicentre study including consecutive eyes with ≤250 μm idiopathic macular hole treated with vitrectomy. The primary outcome was hole closure rate.

Ophthalmic and Physiological Optics, Volume 45, Issue 3, Page 799-809, May 2025.Abstract Purpose Little is known about the quality of optometrists' referrals to secondary care for neovascular age‐related macular degeneration (nAMD), despite the need for timely intervention. We analysed the content and accuracy of optometrists' referrals for nAMD.
