Wavelength‐Dependent Photobiomodulation Regulates Macrophage Polarization via Mitochondrial Dynamics and Metabolic Reprogramming

open access: yesAdvanced Science, EarlyView.
Light wavelength encodes distinct macrophage fates through mitochondrial and metabolic remodeling. Red 625 nm irradiation induces glycolysis, mitochondrial fission, and M1 polarization, whereas near‐infrared 850 nm irradiation promotes fatty acid oxidation, mitochondrial fusion, and M2 polarization.

Microblasting Wound Dressings Mechanically Disrupt Polymicrobial Biofilms to Enhance Healing in Treatment‐Resistant Wounds

open access: yesAdvanced Science, EarlyView.
Treatment‐resistant wounds caused by polymicrobial biofilms are refractory to conventional therapies due to the dense extracellular matrices. We developed μBLAST, a microblasting wound dressing that combines MnO2‐doped biosilica and a H2O2‐releasing mesh to generate localized oxygen microbubbles that mechanically disrupt biofilms.

Field‐Frustrated Cooperative Distortions: Suppressing Jahn‐Teller Ordering via Microwave Annealing

open access: yesAdvanced Science, EarlyView.
Microwave annealing decouples local Jahn‐Teller distortions from long‐range cooperative ordering in CuFe2O4, stabilizing a metastable cubic phase that remains locally distorted yet globally symmetry‐frustrated. Synchrotron XRD, PDF, XPS, and in situ thermal cycling reveal how non‐equilibrium MW‐phonon interactions suppress cooperative orbital‐lattice ...

Dynamic Evolution‐Controlled Parabolic‐Shaped Microstructures for Ultra‐Black Surface via Self‐Assembled Microsphere Mask Etching

open access: yesAdvanced Science, EarlyView.
A robust, substrate‐independent fabrication approach overcomes the spectral and geometric limitations of traditional stray‐light suppression. By combining ink spray‐coating with self‐assembled microsphere mask etching, this method produces parabolic‐shaped microstructures on diverse planar and curved engineering components.

Use of the Disposable Contact Lens as a Bandage Contact Lens

Archives of Ophthalmology, 1991
To the Editor. —Therapeutic soft contact lenses can be very useful in treating a variety of ocular surface problems, including bullous keratopathy, disorders of corneal wetting, conjunctival diseases, epithelial defects, and corneal ulcers. 1,2 Since July 1989, we have been using disposable extended-wear contact lenses (Acuvue [8.6-mm base curve, 14 ...

Contact lens complications

The American Journal of Emergency Medicine, 1990
Contact lens wearers who develop complications related to their lens use are likely to present to emergency departments for care. The pathophysiology of contact lens complications is outlined, and clinical presentations of various conditions related to both soft and hard lens wear are summarized.

Contact Lens Disinfectants

Ophthalmology, 2007
Purpose: To investigate the susceptibility of Pseudomonas aeruginosa and Fusarium solani , alone and together, to 4 contact lens disinfecting solutions. Methods: Five P. aeruginosa and one F. solani isolates were used. The following solutions were tested: Complete Moisture Plus (AMO Ireland, Dublin, Ireland), ReNu with MoistureLoc (Bausch ...

Contact lens complications

Ophthalmology Clinics of North America, 2003
Complications associated with contact lenses range from mild to severe and occur with all lens modalities. Contact lens wear can cause a change in corneal physiology, which can lead to epithelial, stromal, and endothelial compromise. Other complications include lens deposition, allergic conjunctivitis, giant papillary conjunctivitis, peripheral ...

Contact lens standards

Contact Lens and Anterior Eye, 1998
The British Standards Institution (BSI) is in the process of publishing an extensive series of standards relating to contact lenses which were originally formulated as International and European Standards. Standards specifying tolerance limits for the manufacture of rigid and hydrogel lenses have been based upon data on reproducibility derived from ...
