Impact of Centralisation of Radical Prostatectomy Driven by the Introduction of Robotic Systems on Positive Surgical Margin and Biochemical Recurrence in pT2 Prostate Cancer.
Cancer Med
January 2025
Department of Urology, Queen Elizabeth University Hospital, Glasgow, UK.
Background: To assess how centralisation of cancer services via robotic surgery influenced positive surgical margin (PSM) occurrence and its associated risk of biochemical recurrence (BCR) in cases of pT2 prostate cancer (PC).
Methods: Retrospective analysis of all radical prostatectomy (RP) cases performed in the West of Scotland during the period from January 2013 to June 2022. Primary outcomes were PSM and BCR.
Somatic CAG repeat expansion in blood associates with biomarkers of neurodegeneration in Huntington's disease decades before clinical motor diagnosis.
Nat Med
January 2025
Huntington's Disease Centre, Department of Neurodegenerative Disease, UCL Queen Square Institute of Neurology, University College London, London, UK.
Huntington's disease (HD) is an autosomal dominant neurodegenerative disease with the age at which characteristic symptoms manifest strongly influenced by inherited HTT CAG length. Somatic CAG expansion occurs throughout life and understanding the impact of somatic expansion on neurodegeneration is key to developing therapeutic targets. In 57 HD gene expanded (HDGE) individuals, ~23 years before their predicted clinical motor diagnosis, no significant decline in clinical, cognitive or neuropsychiatric function was observed over 4.

Alzheimers Dement
January 2025
Department of Neurology, Mayo Clinic, Rochester, Minnesota, USA.
Introduction: Greater white matter hyperintensities (WMHs) on magnetic resonance imaging (MRI) are seen with transactive response DNA-binding protein 43 (TDP-43) pathology in frontotemporal lobar degeneration (FTLD-TDP). WMH associations with TDP-43 pathology in Alzheimer's disease (AD-TDP) remain unclear.
Methods: A total of 157 participants from Mayo Clinic Rochester with autopsy-confirmed AD, known TDP-43 status, and antemortem fluid-attenuated inversion recovery (FLAIR) MRI were included.
Artificial intelligence in cryo-EM protein particle picking: recent advances and remaining challenges.
Brief Bioinform
November 2024
Department of Electrical Engineering and Computer Science, University of Missouri, Columbia, MO 65211, United States.
Cryo-electron microscopy (cryo-EM) has revolutionized structural biology by enabling the determination of high-resolution 3-Dimensional (3D) structures of large biological macromolecules. Protein particle picking, the process of identifying individual protein particles in cryo-EM micrographs for building protein structures, has progressed from manual and template-based methods to sophisticated artificial intelligence (AI)-driven approaches in recent years. This review critically examines the evolution and current state of cryo-EM particle picking methods, with an emphasis on the impact of AI.

Shanghai Institute of Applied Physics, Chinese Academy of Sciences, Shanghai 201800, People's Republic of China.
Heat-shock protein 90 (HSP90) is a highly active molecular chaperone that plays a crucial role in cellular function. It facilitates the folding, assembly and stability of various oncogenic proteins, particularly kinases and transcription factors involved in regulating tumor growth and maintenance signaling pathways. Consequently, HSP90 inhibitors are being explored as drugs for cancer therapy.
