Impact of MRI slice thickness and fiducial marker orientation on geometric accuracy in multi‐echo GRE imaging for prostate radiotherapy planning

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Precise target definition in prostate radiotherapy requires accurate computed tomography (CT)‐magnetic resonance imaging (MRI) image registration using gold fiducial markers (GFMs). While multi‐echo gradient recalled echo (ME GRE) sequences facilitate GFM identification, the quantitative impact of acquisition parameters on physical ...

PlantGFM: A Genomic Foundation Model for Discovery and Creation of Plant Genes

Advanced Science, Volume 13, Issue 46, 17 August 2026.
A plant genomic foundation model pre‐trained on 12 species enables both accurate gene prediction and de novo gene design. Through AI‐human knowledge screening, seven designed sequences showed transcriptional activity in plants, with two expressing stable proteins—demonstrating the first DNA‐RNA‐protein expression of LLM‐generated genes in plants and ...

Pituitary abscess syndrome in a greater kudu (Tragelaphus strepsiceros)

Veterinary Record Case Reports, Volume 14, Issue 3, August 2026.
Abstract An adult male greater kudu (Tragelaphus strepsiceros) presented for a fractured distal left horn. Twelve weeks later, lethargy, pruritus and left periocular swelling were noted. Avulsion of the left horn occurred 1 month later, revealing a necrotic horn base.

Real‐World Outcomes of FLAG‐Ida Regimen in 1079 Adult Patients With First Relapsed/Refractory AML: A PETHEMA Study

American Journal of Hematology, Volume 101, Issue 7, Page 1692-1705, July 2026.
ABSTRACT In a large multicenter real‐world cohort, we aimed to evaluate outcomes of FLAG‐Ida salvage therapy for relapsed/refractory (R/R) acute myeloid leukemia (AML) and validated the SALFLAGE prognostic score. We analyzed 1079 adults with R/R AML treated across 112 PETHEMA institutions over 26 years (1998–2024), including patients with primary ...

An Immune Dysfunction Signature Score Predicts Survival in MDS Patients: Insights From a Longitudinal, Multicenter Study

Cancer Science, Volume 117, Issue 7, Page 1921-1934, July 2026.
An immune dysfunction score (IDS) provides independent prognostic information in MDS and CMML, complements current risk models, mirrors disease changes, and reflects underlying immune impairment. IDS may also highlight therapeutic sensitivities, supporting its use as a practical biomarker for risk stratification and clinical follow‐up.

Modeling and Control of Grid Forming Converters: A Systematic Review

IEEE Access
In electrical power systems where the proportion of synchronous generators (SG) is gradually decreasing, grid-forming (GFM) converters need to be installed and controlled to meet all the system requirements that SGs have provided to date.
