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

open access: yesFEBS 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 ...

Non-invasive Raman spectroscopy with wavefront shaping and wavelength modulation to quantify methanol in bottled spirits

open access: yesJPhys Photonics
Non-destructive, on-site screening methods capable of molecular analysis directly through commercial packaging remain a significant challenge for safety, security, and quality assurance.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Single level integrated packaging modules for high performance electronic systems

open access: yes, 2001
In this paper, we studied a novel packaging scenario that aims to integrate or eliminate the existing multilevel packaging hierarchies toward single level integration.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Hermetic packaging for microwave modules. Final report

open access: yes, 1996
Microwave assemblies, such as radar modules, require hermetically sealed packaging. Since most of these assemblies are used for airborne applications, the packages must be lightweight.

Measurement and Analysis of Interconnects’ Resonance and Signal/Power Integrity Degradation in Glass Packages

open access: yesMicromachines
In this article, resonance phenomena of high-speed interconnects and power delivery networks in glass packages are measured and analyzed. The resonances are generated in the interconnection by the physical dimension, cancelation of reactance components ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

High-Performance EMI Shielding Film Based on Low-Dk Polyimide and Trimodal Ag Ink for High-Speed Signal Integrity Enhancement

open access: yesMicro
Electromagnetic interference (EMI) shielding is critical for maintaining signal integrity in high-speed electronic packaging. However, conventional shielding approaches face limitations in process complexity and spatial efficiency.

phylosignal: an R package to measure, test, and explore the phylogenetic signal

open access: yesEcology and Evolution, 2016
AbstractPhylogenetic signal is the tendency for closely related species to display similar trait values as a consequence of their phylogenetic proximity. Ecologists and evolutionary biologists are becoming increasingly interested in studying the phylogenetic signal and the processes which drive patterns of trait values in the phylogeny.
