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

Therapeutic 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.

Nondestructive Characterization of Damaged Bonds

, 1993
This paper presents a new technique to characterize the damage of a bonded component. The theoretical analysis models a damaged bond as a random distribution of small interphase cracks and cavities. Interaction of ultrasonic waves with these interfacial cracks are studied by a differential self-consistent scheme (DSS) in conjunction with the ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Characterization of Impact Damage in Composites

, 1987
This paper will report on the results of a study of the application of advanced digital data acquisition technology to the problem of impact damage in composites. This area was chosen for the study because of the importance of developing better damage characterization methods and the limited scope of the damage itself.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Characterization of Radiation Damage in Tungsten

, 2020
Tungsten as plasma-facing material of a future fusion reactor will be subjected to high-flux neutron irradiation. The defect creation and its influence on hydrogen retention in tungsten irradiated with different ions were investigated. The microstructure and hydrogen retention was studied with transmission electron microscopy, positron annihilation ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
