Neuromuscular junction degeneration is a prominent aspect of sarcopenia, the age-associated loss of skeletal muscle integrity. Previously, we showed that muscle stem cells activate and contribute to mouse neuromuscular junction regeneration in response to denervation (Liu et al., 2015). Here, we examined gene expression profiles and neuromuscular junction integrity in aged mouse muscles, and unexpectedly found limited denervation despite a high level of degenerated neuromuscular junctions. In... Read more

Access to MRI is limited for patients with DBS implants due to safety hazards, including radiofrequency heating of tissue surrounding the leads. Computational models provide an exquisite tool to explore the multi-variate problem of RF implant heating. We used a computational approach to assess RF heating around tips of bilateral DBS leads during MRI at 1.5T and 3T using realistic DBS lead models. A substantial difference was found between the SAR and temperature rise at the tip of right and l... Read more

Combined expansion and lattice light sheet microscopy enables high
speed, nanoscale molecular imaging of neural circuits over large volumes.
Optical and electron microscopy have made tremendous inroads in understanding the complexity of the brain, but the former offers insufficient resolution to reveal subcellular details and the latter lacks the throughput and molecular contrast to visualize specific molecular constituents over mm-scale or larger dimensions. We combined expansio... Read more

We introduce the application of microbial-induced calcite precipitation via the ureolytic soil bacterium Sporosarcina Pasteurii in freeze-dried form, as a means of enhancing overall MICP efficiency and reproducibility for geotechnical engineering applications. We show that the execution of urea hydrolysis and CaCO3 precipitation persist as a “cell-free” mechanism upon the complete breakdown of rehydrated cell clusters. Further, strength and stiffness parameters of bio-cemented ... Read more

This work demonstrated the importance and feasibility of experimental image
to simulation workflow. The workflow is successfully applied to a food processing study, where multiphysics and multiscale modeling
based on 3D experimental image reconstruction contributes to the preservation of corn, one of the major food sources for the world population.
Corn kernels have a complex structure as they are composed of a pericarp layer outside and contain hard and soft endosperm and ... Read more

Composite cathodes comprising nanoscale
powders are expected to impart with high specific surface
area and triple phase boundary (TPB) density, which will lead
to better performance.
However, uniformly mixing nanosized heterophase powders remains a challenge due to their high surface energy and thus ease with which they agglomerate into their individual phases during the mixing and sintering
processes. In this study, we successfully synthesized La0.6Sr0.4Co0.2Fe... Read more

Lifetime-limiting failure of fuel cell membranes is generally attributed to their chemical and/or mechanical degradation. Although both of these degradation modes occur concurrently during operational duty cycles, their uncoupled investigations can provide useful insights into their individual characteristics and consequential impacts on the overall membrane failure.
X-ray computed tomography is emerging as an advantageous tool for fuel cell failure analysis due to its non-destructive ... Read more

Human skeletal remains from archaeological contexts occasionally present signs of traumatic injuries from weapons, revealing, for example, the degree of interpersonal violence, the type of weapon and the sequence of events of a specific historical context.
Traumatic lesions are generally analyzed using macroscopic and microscopic methods, which are not necessarily integrated in the same study. In this study, we employed a multi-analytical approach to determine i... Read more

The authors present for the first time a new methodology of contrast enhancement for 3D imaging, including novel advanced quantification, on a commercial Lithium Iron Phosphate (LFP) LiFePO4 cathode. The aim of this work is to improve the quality of the 3D imaging of challenging battery materials by developing methods to increase contrast between otherwise previously poorly differentiated phases. This is necessary to enable capture of the real geometry of electrode microstructures... Read more

Macroautophagy is morphologically characterized by autophagosome formation. Autophagosomes are double-membraned vesicles that sequester cytoplasmic components for further degradation in the lysosome. Basal autophagy is paramount for intracellular quality control in post-mitotic cells but, surprisingly, the number of autophagosomes in post-mitotic neurons is very low, suggesting that alternative degradative structures could exist in neurons…Read more
