Doença de Fabry Fabry disease

Anais Brasileiros de Dermatologia, 2009
A doença de Fabry é enfermidade de armazenamento lisossômico rara, ligada ao cromossomo-X, causada pela deficiência parcial ou completa da enzima alfagalactosidase A. O defeito resulta no acúmulo de globotriaosilceramida no endotélio vascular e tecidos viscerais, sendo a pele, o coração, os rins e o sistema nervoso central os mais afetados.

Reconfigurable Geometric Phase Matching by Multilayered Nonlinear Thin‐Film Crystals

Laser &Photonics Reviews, EarlyView.
The concept of geometric phase matching is demonstrated as a dynamically reconfigurable approach for tunable nonlinear wave mixing in multilayered nonlinear thin‐film crystals. Experimental results reveal full modulation in a bilayer structure and near‐perfect spin‐selective phase matching of second‐harmonic generation in an eight‐layer configuration ...

Room‐Temperature Polariton Condensation Into Superscar Modes in Growth‐Defined Triangular Micro‐Prism Resonators

Laser &Photonics Reviews, EarlyView.
High‐Q superscar modes in growth‐defined triangular GaN micro‐prism resonators enable strong exciton–photon coupling and room‐temperature polariton condensation, offering a scalable platform for integrated III‐nitride polariton devices. ABSTRACT Group III‐nitride semiconductors are regarded as key materials for realizing polariton devices operating at ...

Heterogeneous Integration of Multi‐Band Mode‐Locked and Single‐Mode Lasers on an Extended Commercial SiN Platform

Laser &Photonics Reviews, EarlyView.
Micro‐transfer printing enables GaAs and InP gain materials to be integrated on a commercial silicon nitride photonic platform. The resulting chip supports O‐ and C‐band comb and single‐mode lasers, demonstrating a scalable route toward multi‐material, multi‐wavelength, and multifunctional integrated light sources.

Wavefront Shaping for Optimal Extinction of Focused Light by Individual Nanoscatterers

Laser &Photonics Reviews, EarlyView.
Wavefront shaping enables near‐complete optical extinction by nanoscatterers separated from a planar reflector. Time‐reversed emission profiles provide optimal illumination conditions, yielding 70% extinction from a single plasmonic nanoparticle and up to 90% from sub‐wavelength nanoparticle clusters, offering a promising route to efficient in‐ and out‐

Time‐Modulated Optomechanics Reveal Energy Flow and Inelastic Interactions Between Acoustic Phonons in Nanomembranes

Laser &Photonics Reviews, EarlyView.
Temporal interfaces are abrupt refractive index changes used in time‐varying optics, but also transitions to nonequilibrium states. This work explores the inelastic scattering of time‐varying light by nonthermal acoustic phonons in the vicinity of temporal interfaces.

Pulmonary involvement in Fabry disease

, 2006
Pulmonary involvement in Fabry disease has received less attention than the effects of the disease on the kidneys, nervous system or heart. However, data from FOS -the Fabry Outcome Survey - are now helping to elucidate the pulmonary manifestations of ...

Transmission‐Mode Silicon‐Rich Nitride Mie‐Void Metasurfaces in the Visible

Laser &Photonics Reviews, EarlyView.
Transmission‐mode Mie‐void metasurfaces are demonstrated in silicon‐rich nitride, where localized void resonances hybridize with slab‐guided and Fabry–Pérot‐like modes in a finite film, producing a quantified avoided crossing between coupled modes. Controlled void depth tunes the visible transmission spectrum, enabling structural color and spatial ...

Integration of III‐V Quantum Dot Photonic Devices on Silicon Nitride via Lithography‐Aligned Micro‐Transfer Printing

Laser &Photonics Reviews, EarlyView.
Lithography‐aligned micro‐transfer printing integrates unprocessed InAs/GaAs quantum dot membranes with silicon nitride photonic circuits. Post‐transfer patterning defines quantum dot photonic devices directly on the target chip, enabling precise GaAs–SiNx coupling, purcell‐enhanced single photon emission, and scalable on‐chip routing and correlation ...

Toward Low‐Power Laser Refrigeration ‐ Cooling a Resonant WGM Crystalline Cavity

Laser &Photonics Reviews, EarlyView.
Laser refrigeration offers a method to cool solids to low temperatures by using only light. By illuminating bulk crystals doped with rare‐earth ions one can engineer the emitted fluorescent light to be at shorter wavelengths than the pump light ‐ thus extracting heat/phonons from the solid and cooling the crystals.
