Correlating the Evans index and bicaudate index with ventricle volume at the three kinds of scanning baselines

Brain Research Bulletin
Purpose: Evans' Index (EI) and Bicaudate Index (BCI), as two-dimensional linear indexes, are commonly used to evaluate ventricle size. This study is investigated the differences in linear measures at the three kinds of scanning baselines and their ...

Formation of atom wires on vicinal silicon

, 2004
The formation of atomic wires via pseudomorphic step-edge decoration on vicinal silicon surfaces has been analyzed for Ga on the Si(112) surface using Scanning Tunneling Microscopy and Density Functional Theory calculations. Based on a chemical potential

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

A Joint Compensation Method for Repositioning Error and Atmospheric Phase Screen of Ground-Based SAR

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In the monitoring of discontinuous ground-based synthetic aperture radar (GB-SAR), challenges such as repositioning error and atmospheric phase screen (APS) can significantly impact the accuracy of deformation inversion. Existing compensation methods are

Linear Motor Powered Transportation [Scanning the Issue] [PDF]

Proceedings of the IEEE, 2009
This special issue on linear-motor powered transportation covers both supporting technologies and innovative transport systems in various parts of the World, as this technology moves from the lab to commercial operations. There are many types of linear motors, but most of those discussed in these papers are the short primary linear induction motor (LIM)

β‐TrCP overexpression enhances cisplatin sensitivity by depleting BRCA1

Molecular Oncology, EarlyView.
Low levels of β‐TrCP (Panel A) allow the accumulation of BRCA1 and CtIP, which facilitate the repair of cisplatin‐induced DNA damage via homologous recombination (HR) and promote tumor cell survival. In contrast, high β‐TrCP expression (Panel B) leads to BRCA1 and CtIP degradation, impairing HR repair, resulting in persistent DNA damage and apoptosis ...

PARP inhibitors elicit distinct transcriptional programs in homologous recombination competent castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
PARP inhibitors are used to treat a small subset of prostate cancer patients. These studies reveal that PARP1 activity and expression are different between European American and African American prostate cancer tissue samples. Additionally, different PARP inhibitors cause unique and overlapping transcriptional changes, notably, p53 pathway upregulation.
