Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Rates of convergence of powered order statistics from general error distribution
Let $ \{X_{n}: n\ge 1\} $ be a sequence of independent random variables with common general error distribution $ \hbox{GED} (v) $ with shape parameter v>0, and let $ M_{n,r} $ denote the r-th largest order statistics of $ X_{1}, X_{2}, \ldots, X_{n ...

Design and analysis strategies for robust microbiome ageing research
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

Photon statistics on the extreme entanglement [PDF]
AbstractThe effects of photon bunching and antibunching correspond to the classical and quantum features of the electromagnetic field, respectively. No direct evidence suggests whether these effects can be potentially related to quantum entanglement.

Single‐cell DNA methylation (scDNAme) profiling maps epimutational clonal evolution, revealing mechanisms of malignancy and therapeutic resistance across diverse cancer types. By providing a high‐resolution landscape of intratumoral heterogeneity, these technologies empower precise patient stratification, guide the development of enhanced ...

Extreme dry and wet events in Iceland: Observations, simulations and scenarios
Monthly extremes of dryness and wetness in Iceland are analysed based on the standardised precipitation index (SPI). The analysis is performed for observations and four sets of coupled atmosphere-ocean climate model simulations (ECHAM5/MPI-OM) to link ...

Local impact analysis of climate change on precipitation extremes: are high-resolution climate models needed for realistic simulations? [PDF]
This study explores whether climate models with higher spatial resolutions provide higher accuracy for precipitation simulations and/or different climate change signals.

Gut microbiota alterations in patients with non‐small‐cell lung cancer undergoing chemoradiotherapy
We investigated the impact of concurrent chemoradiotherapy (CRT) on the gut microbiota in patients with locally advanced non‐small‐cell lung cancer. Overall gut microbiota composition remained largely stable throughout CRT while antibiotic exposure may influence microbial diversity.
