Analysis of clinical characteristics, treatment response, and prognosis among 67 patients with anaplastic multiple myeloma

open access: yesWorld Journal of Surgical Oncology
Background Anaplastic multiple myeloma (AMM) is a type of distinctive MM with a poor prognosis. AMM is mostly reported as individual cases, an accurate incidence and strict clinical definition are lacking.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Dynamics of spin transport in voltage-biased Josephson junctions

open access: yes, 2007
We investigate spin transport in voltage-biased spin-active Josephson junctions. The interplay of spin filtering, spin mixing, and multiple Andreev reflection leads to nonlinear voltage dependence of the dc and ac spin current.

CSF characteristics in early-onset multiple sclerosis

open access: yesNeurology, 2004
The authors studied CSF characteristics in 136 patients with multiple sclerosis (MS) with a disease onset before age 16. In the initial diagnostic lumbar puncture, CSF-pleocytosis was observed in 66%, blood-CSF barrier dysfunction in 13%, and oligoclonal IgG in 92% of the early-onset MS (EOMS) patients.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Multiple Focal Nodular Hyperplasia and Steatohepatitis: Atypical Imaging Characteristics

open access: yesCanadian Journal of Gastroenterology, 2001
Focal nodular hyperplasia is a rare, benign condition of the liver. A 28-year-old woman with malignant melanoma, mild liver enzyme abnormalities, steatohepatitis and newly documented hepatic lesions is described.

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.

Structural biology of ferritin nanocages

open access: yesFEBS 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 ...

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 ...
