MRI‐based radiomics model for predicting VEGFA expression and prognosis in lower‐grade glioma

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background Gliomas are the most common primary tumors of the central nervous system. Their treatment remains highly challenging, with high rates of associated disability and mortality. Conventional prognostic indicators no longer adequately satisfy the clinical demands of precision medicine.

Transverse Relaxation Time Constant of Cystathionine in Human Glioma at 3 T

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1076-1082, September 2026.
ABSTRACT Purpose Cystathionine (Cth) has emerged as a promising biomarker for identifying 1p/19q codeleted gliomas. However, little is known about the T2 relaxation time constant of Cth in gliomas. The aim of this study was to measure the T2 of Cth in vivo in glioma and compare it to the T2s of other metabolites at 3 T.

Diagnostic Accuracy of APTw and NOEw MRI Metrics for IDH Mutation and 1p/19q Codeletion Prediction in Gliomas

NMR in Biomedicine, Volume 39, Issue 9, September 2026.
We evaluated how confounding effects from fluid, macromolecules and T1 relaxation impact the performance of APTw and NOEw metrics for noninvasive glioma classification at 3 T. Corrected APTw metrics showed the highest discriminations of IDH‐mutant from wild‐type gliomas (AUC = 0.94–0.96), whereas NOEw metrics did not differ between groups.

Rapid Screening of Bacterial Chemoeffectors of Pseudomonas parafulva Using a CheA ATPase Activity‐Based Assay

Environmental Microbiology, Volume 28, Issue 9, September 2026.
We present a scalable, cell‐free, and straightforward NADH‐coupled CheA ATPase assay for quickly screening potential bacterial chemoeffectors and integrate it into a pipeline to identify both the chemoeffectors and their corresponding chemoreceptors in Pseudomonas parafulva, enabling systematic exploration of chemotactic sensing.

Rewiring Carbon Metabolism in Bacillus methanolicus via Heterologous Phosphoketolase Expression Enhances Biomass Yield From Methanol and Reduces CO2 Loss

Microbial Biotechnology, Volume 19, Issue 9, September 2026.
Introducing a phosphoketolase pathway into Bacillus methanolicus enhances methanol‐to‐biomass yields by 18%–24% and reduces CO2 evolution by up to 12%. Coupled with a tunable expression system, this work demonstrates improved carbon conservation and expands metabolic engineering strategies for methylotrophs.
