Multiplexed Detection of Respiratory Viruses Using Surface Plasmon Resonance Spectroscopy With Ultrathin Carbon Nanomembranes

Advanced Healthcare Materials, EarlyView.
An ultrathin azide‐functionalized carbon nanomembrane (N3‐CNM) provides a versatile biointerface for antibody immobilization on gold SPR sensors. Integrated with a multichannel SPR platform, the functionalized surface enables label‐free, simultaneous detection of SARS‐CoV‐2, Influenza A, and RSV antigens, demonstrating the potential of CNM‐based ...

The influence of magnification correction on macular retinal/choroidal thickness and vessel density measurements using optical coherence tomography angiography in 4–17-year-old students

Photodiagnosis and Photodynamic Therapy
Background: Transverse macular measurements from optical coherence tomography angiography (OCTA) depend on ocular magnification, which varies with axial length (AL); in growing children, whether correcting for magnification alters macular thickness and ...

GDNF‐Enriched Small Extracellular Vesicle‐Loaded ROS‐Scavenging Hydrogel Promotes Neural Regeneration After Spinal Cord Injury

Advanced Healthcare Materials, EarlyView.
A glial cell line‐derived neurotrophic factor (GDNF)‐enriched small extracellular vesicle‐loaded reactive oxygen species (ROS)‐scavenging hydrogel integrates sustained neurotrophic delivery with local modulation of oxidative and inflammatory stress after spinal cord injury. The composite hydrogel improves local vesicle retention, protects neural tissue,

Microwave Diagnostics for the Measurement of Plasma Density in a Cylindrical Metal Vessel.

Kakuyūgō kenkyū, 1972
Microwave interference method for the measurement of the electron density of plasmas contained in a metal cylinder is studied theoretically and experimentally. It is pointed out that the interferometer signal through the metal vessel can not eliminate of the cavity mode effect, even if the dimension of the vessel is large compared with the wavelength ...

Density of Blood and Lymphatic Vessels in Stretch Marks: A Preliminary Study

In Vivo
Although stretch marks are not a medical condition, they are an esthetic defect and can have a negative impact on self-esteem. The causes of stretch marks are mainly hormonal factors, rapid weight gain, weight loss, pregnancy, and genetic factors. The aim of this study was to assess the expression level of markers of angiogenesis (CD31+, CD34+) and ...
