In Vivo Corrosion of Acetabular Modular Tapers Reduces Local Corrosion Resistance: Near‐Field Electrochemical Impedance Spectroscopy as an Indicator of the Type and Severity of Corrosion in Retrieved Hip Implants

open access: yesJournal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 1, January 2026.
ABSTRACT Retrieved hip implant components experience a range of corrosion types and severity, often on small surface areas of the taper region. Tribocorrosion‐related damage within modular taper regions and resulting changes of the oxide‐covered surface can alter the local impedance of the interface.

Phase-field investigation of intergranular corrosion mechanism and kinetics in aluminum alloys

open access: yesJournal of Materials Research and Technology
The resistance to intergranular corrosion (IGC) is crucial for 7xxx series high-strength aluminum alloy. The grain boundary characteristics and nanoscale intergranular precipitates are the most significant factors affecting the IGC performance of alloys.

Beyond PD‐1/PD‐L1: New Immune Checkpoints and Therapeutic Combinations in Cancer Immunotherapy

open access: yesMedicine Bulletin, Volume 2, Issue 1, Page 61-93, January 2026.
ABSTRACT Recently, immune checkpoint inhibitors (ICIs), particularly PD‐1/PD‐L1 and CTLA‐4 inhibitors, have revolutionized cancer treatment, significantly improving survival rates for various malignancies. However, ICI therapies targeting single checkpoints on T cells still face numerous challenges, such as low response rates and post‐treatment ...

Phosphorylation of iRhom2 Controls Stimulated Proteolytic Shedding by the Metalloprotease ADAM17/TACE

open access: yesCell Reports, 2017
Cell surface metalloproteases coordinate signaling during development, tissue homeostasis, and disease. TACE (TNF-α-converting enzyme), is responsible for cleavage (“shedding”) of membrane-tethered signaling molecules, including the cytokine TNF, and ...

Phylogenetic analysis of paired breast carcinomas identifies genetic events associated with clonal recurrence and invasive progression

open access: yesThe Journal of Pathology, Volume 268, Issue 1, Page 1-12, January 2026.
Abstract Development of ipsilateral breast carcinoma following a diagnosis of breast ductal carcinoma in situ (DCIS) has been assumed to represent recurrence of the primary tumour. However, this may not always be the case, and it is important to determine how often such recurrences represent new tumours.

Conservation challenges and opportunities for native apple (Malus) species in Canada

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 134-156, January 2026.
Apple, one of the world's most widely cultivated and economically important fruit crops, has two wild relatives native to Canada. In this review, we describe the importance of these native apple species to Indigenous heritage and the current threats the species faces due to pests, diseases, and habitat loss.
