Lung Ultrasound for the Detection of Radiologic Progression of Interstitial Lung Abnormalities in Patients With Rheumatoid Arthritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Interstitial lung disease (ILD) is an important extra‐articular manifestation of rheumatoid arthritis (RA) associated with high mortality and morbidity. Lung ultrasonography (LUS) has recently emerged as a possible screening tool. We assessed the role of LUS in monitoring radiologic progression and the development of new interstitial lung ...

Expert Perspectives: Defining and Managing Progressive Pulmonary Fibrosis in Systemic Sclerosis

open access: yesArthritis &Rheumatology, EarlyView.
Systemic sclerosis–associated interstitial lung disease (SSc‐ILD) is one of the leading causes of morbidity and mortality in SSc, affecting up to three‐quarters of patients. The disease course is highly heterogeneous, ranging from indolent, nonprogressive forms to rapidly progressive pulmonary fibrosis (PPF).

Two‐Photon Mediated Cancer Therapy: A Comprehensive Review on Two‐Photon Photodynamic Therapy and Two‐Photon‐Activated Therapeutic Delivery Systems

Advanced Functional Materials
AbstractTwo‐photon excitation (2PE) represents substantial advantages in biophotonics over traditional one‐photon excitation (1PE), offering enhanced spatial resolution and deeper tissue penetration capabilities. Since its introduction in the 1990s, two‐photon excited microscopy has spurred the rapid emergence of novel 2PE‐based applications, including

Two-Photon Photodynamic Therapy

Journal of Clinical Laser Medicine & Surgery, 1997
We demonstrate the use of infrared excitation in conjunction with an efficient two-photon absorbing dye and a photosensitizer in photodynamic therapy.An efficient two-photon absorbing dye is excited by short infrared (800 nm) laser pulses, which transfer its energy to the photosensitizer and the photosensitizer, in turn, generates the singlet oxygen.A ...

Biological Considerations When Comparing Proton Therapy With Photon Therapy

Seminars in Radiation Oncology, 2013
Owing to the limited availability of data on the outcome of proton therapy, treatments are generally optimized based on broadly available data on photon-based treatments. However, the microscopic pattern of energy deposition of protons differs from that of photons, leading to a different biological effect.

Motion in radiotherapy: photon therapy

Physics in Medicine and Biology, 2012
This review considers the management of motion in photon radiation therapy. An overview is given of magnitudes and variability of motion of various structures and organs, and how the motion affects images by producing artifacts and blurring. Imaging of motion is described, including 4DCT and 4DPET.

Exit dose studies in megavoltage photon therapy

The British Journal of Radiology, 1983
A coin-shaped ionisation chamber, orientated with its thin window facing away from the radiation source, was used to investigate the dose perturbations caused by the absence of back-scattering material near the exit surface of solid phantoms. Cobalt 60 and 4, 8 and 16 MV X-ray beams were used in the study. With no scattering material beyond the chamber

Molecular photosensitisers for two-photon photodynamic therapy

Chemical Communications, 2017
With the recent development of clinical two-photon microscopes or endoscopes, new photosensitisers for two-photon photodynamic therapy are the subject of increasing interest. Herein, we review the advances within the ten last years of molecular two-photon photosensitisers.
