Metal sensitivity in total joint arthroplasty: None of the current diagnostic tests are reliable, sensitive and specific enough to guide treatment decisions!

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, Volume 33, Issue 9, Page 3269-3285, September 2025.
ABSTRACT Purpose This systematic review was conducted to evaluate the current literature on metal hypersensitivity in patients undergoing joint arthroplasty. The aims of the study were to report diagnostic tools used to assess metal hypersensitivity and to report complications arising in patients who are hypersensitive to nickel or other metals ...

Unusual Plastoquinones in Non‐Phototrophic Nitrifying Bacteria

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 4, August 2025.
Chemolithoautotrophic nitrifying bacteria of the genus Nitrospira exclusively possess unusual methyl‐plastoquinones with a standard redox potential below that of canonical plastoquinone and ubiquinone, suggesting functional roles in bidirectional electron transport.

Promoter methylation status of Ras-Association domain family member in pheochromocytoma [PDF]

open access: yes, 2015
Pheochromocytomas (PCCs) are rare neuroendocrine tumors that arise from the medulla of the adrenal gland or the sympathetic ganglia and are characterized by the secretion of catecholamines.

Biodegradable, Antibacterial TCP Implant Coatings With Magnesium Phosphate‐Based Supraparticles

open access: yesJournal of Biomedical Materials Research Part A, Volume 113, Issue 7, July 2025.
ABSTRACT This work highlights the potential of porous, bioactive coatings to advance implant technology and address critical clinical challenges. A key issue in implant coatings is to achieve the balance between infection prevention and successful osseointegration.

Single and Double Knockouts of the Genes for Photosystem I Subunits G, K, and H of Arabidopsis [PDF]

open access: yes, 2002
Photosystem I (PSI) of higher plants contains 18 subunits. Using Arabidopsis En insertion lines, we have isolated knockout alleles of the genes psaG, psaH2, and psaK, which code for PSI-G, -H, and -K.

A Novel Function of NaV Channel β3 Subunit in Endothelial Cell Alignment Through Autophagy Modulation

open access: yesThe FASEB Journal, Volume 39, Issue 11, 15 June 2025.
NaVβ3 expression is increased by laminar shear stress (LSS) through KLF4 induction (1). NaVβ3 is retained within the cell and interacts with mTOR protein and colocalizes partially with LAMP1 and LC3B, lysosome and autophagosome markers, respectively (2). Since SiRNA SCN3B induces the decrease of LC3B expression and cell alignment in response to LSS (3),

Constraint Satisfaction in Current Control of a Five-Phase Drive with Locally Tuned Predictive Controllers [PDF]

open access: yes, 2019
The problem of control of stator currents in multi-phase induction machines has recently been tackled by direct digital model predictive control. Although these predictive controllers can directly incorporate constraints, most reported applications ...

The cyanobacterial ribosomal-associated protein LrtA from Synechocystis sp. PCC 6803 is an oligomeric protein in solution with chameleonic sequence properties [PDF]

open access: yes, 2018
The LrtA protein of Synechocystis sp. PCC 6803 intervenes in cyanobacterial post-stress survival and in stabilizing 70S ribosomal particles. It belongs to the hibernating promoting factor (HPF) family of proteins, involved in protein synthesis. In this

$L_\infty$-Algebra Models and Higher Chern-Simons Theories [PDF]

open access: yes, 2016
We continue our study of zero-dimensional field theories in which the fields take values in a strong homotopy Lie algebra. In a first part, we review in detail how higher Chern-Simons theories arise in the AKSZ-formalism.
