Optical coherence tomography with a Fizeau interferometer configuration [PDF]

open access: yes, 2005
We report the investigation of a Fizeau interferometer-based OCT system. A secondary processing interferometer is necessary in this configuration, to compensate the optical path difference formed in the Fizeau interferometer between the end of the ...

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

High precision dynamic multi-interface profilometry with optical coherence tomography [PDF]

open access: yes, 2011
Optical coherence tomography (OCT) has mostly been used for high speed volume imaging but its profilometry potentials have not been fully exploited. This paper demonstrates high precision (as good as ~50nm) multi-interface profilometry using a Fourier ...

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Optical measurement of guided waves [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2017
This paper demonstrates an optical method for measuring guided waves in plates that is much faster than traditional scanning approaches. By recording the wavefield with a high-speed camera and applying a post-processing method, the wavefield can be extracted from the static and noise components within the measured signal. This technique is demonstrated

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
