Background: Machine learning (ML) is increasingly used to predict clinical deterioration in intensive care unit (ICU) patients through scoring systems. Although promising, such algorithms often overfit their training cohort and perform worse at new hospitals. Thus, external validation is a critical - but frequently overlooked - step to establish the reliability of predicted risk scores to translate them into clinical practice.

Auranofin induces disulfide bond-mimicking S-Au adducts in protein thiol pairs.

J Biol Chem

January 2025

Microbial Biochemistry, Faculty of Medicine, Ruhr University Bochum, 44780 Bochum, Germany. Electronic address:

Auranofin is an inhibitor of human thioredoxin reductase, clinically used in the treatment of rheumatoid arthritis. More recently, it has been shown to possess strong antibacterial activity. Despite the structural dissimilarity and the independent evolutionary origins of human thioredoxin reductase and its bacterial counterpart (TrxB), inhibition of bacterial thioredoxin reductase is often suggested to be a major factor in auranofin's antibacterial mode of action.

Article Synopsis
  • New quinizarin-Au(I)-NHC complexes were developed and fully characterized, demonstrating effective growth inhibition in HeLa cervical cancer cells with IC values between 2.4 and 5.3 μM.
  • Cytotoxicity studies showed that complex 2 b could overcome anthracycline resistance in K562 leukemia cells and worked synergistically with doxorubicin against both sensitive and resistant leukemia cells.
  • The study highlighted that localizing these complexes to mitochondria was crucial for their antiproliferative effects and ability to counteract drug resistance, rather than just overall cytotoxicity.

Intracellular recycling via autophagy is governed by post-translational modifications of the autophagy-related (ATG) proteins. One notable example is ATG4-dependent delipidation of ATG8, a process that plays critical but distinct roles in autophagosome formation in yeast and mammals. Here, we aim to elucidate the specific contribution of this process to autophagosome formation in species representative of evolutionarily distant green plant lineages: unicellular green alga Chlamydomonas reinhardtii, with a relatively simple set of ATG genes, and a vascular plant Arabidopsis thaliana, harboring expanded ATG gene families.

Maternal capabilities to engage in sensitive caregiving are important for infant development and mother-infant-interaction, however, can be negatively affected by cortisol due to a stress response. Previous research suggested that cortisol possibly impairs cognitive functions important for caregiving behavior, which potentially leads to less maternal sensitivity. However, studies investigating the influence of cortisol using endocrine parameters on the mother-infant-interaction during the early postpartum are lacking.

Article Synopsis
  • Tc toxins are harmful proteins from bacteria that can pierce cell membranes, allowing them to introduce toxic enzymes into cells.
  • Their transition from an inactive to an active state has been studied, revealing it takes about 30 hours and involves multiple steps and intermediates.
  • Factors like higher pH and the presence of certain receptors speed up this process, with the actual ejection of the channel happening in under 60 milliseconds, highlighting potential uses for these toxins in medicine and pest control.

The understanding of phenomena falling outside the Ginzburg-Landau paradigm of phase transitions represents a key challenge in condensed matter physics. A famous class of examples is constituted by the putative deconfined quantum critical points between two symmetry-broken phases in layered quantum magnets, such as pressurised SrCu(BO). Experiments find a weak first-order transition, which simulations of relevant microscopic models can reproduce.

Lysosomes are the major cellular organelles responsible for nutrient recycling and degradation of cellular material. Maintenance of lysosomal integrity is essential for cellular homeostasis and lysosomal membrane permeabilization (LMP) sensitizes toward cell death. Damaged lysosomes are repaired or degraded via lysophagy, during which glycans, exposed on ruptured lysosomal membranes, are recognized by galectins leading to K48- and K63-linked poly-ubiquitination (poly-Ub) of lysosomal proteins followed by recruitment of the macroautophagic/autophagic machinery and degradation.
