Understanding extracellular vesicles in antiaging

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Public perspectives on potential changes to malaria deferral criteria in Canada

open access: yesVox Sanguinis, EarlyView.
Abstract Background and Objectives As blood collection agencies (BCAs) seek to increase donor diversity, making changes to eligibility criteria to enable more people to donate is an important consideration. BCAs in Canada have a permanent deferral from whole blood and platelet donation for anyone with a history of malaria, a barrier to donation for ...

Clearance of p16‐positive cardiac cells improves age‐related cardiac remodeling in mice

open access: yesExperimental Physiology, EarlyView.
Abstract Senescent cells are characterized by expression of markers like p16 and secretion of profibrotic and proinflammatory factors. The role of cellular senescence in age‐related cardiac remodeling and dysfunction is incompletely understood. This study aimed to: (i) evaluate the effect of p16‐ positive cell clearance on cardiac function and ...

Senolytics and exercise: Dual modalities for rejuvenating muscle

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The role of senolytics on the heart and skeletal muscle. Senescent cell burden increases with ageing, disuse and disease. The senolytics dasatinib+quercetin (D+Q), navitoclax and fisetin, as well as exercise, eliminate senescent cells, reducing senescent cell burden and their senescence‐associated secretory phenotype (SASP ...

Born early, age fast: Consequences of premature birth on chronic disease and accelerated ageing

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend ELGANs are exposed to several postnatal pro‐oxidant stressors, including ambient and supplemental oxygen, mechanical ventilation, infections, hyperalimentation, excessive glucocorticoids and intermittent hypoxia. Since endogenous antioxidant defences are underdeveloped, this imbalance promotes oxidative stress and inflammation ...

Intrinsic pH chemosensitivity of acutely dissociated medullary serotonergic and retrotrapezoid neurones

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Central respiratory chemoreceptors (CRCs) are critical for maintaining normal systemic levels of pH and PCO2. A CRC must respond to pH via intrinsic mechanisms. Here we quantified intrinsic chemosensitivity of medullary 5‐HT neurones and retrotrapezoid nucleus (RTN) neurones using acute dissociation.

Hypoxia‐inducible factor‐1a (HIF1a) as a context‐dependent integrator of metabolic stress in skeletal muscle

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Hypoxia‐inducible factor‐1a (HIF1a) integrates physiological and pathological inputs in skeletal muscle, including exercise, circadian timing, cytotoxins and disease. These inputs alter mitochondrial oxidative function, redox state, reactive oxygen species, and local oxygen availability, leading to intermittent or sustained HIF1a

HPV Serology and Circulating Viral DNA for Detection, Genotyping, and Measurement of Disease Burden in Oropharyngeal Cancer

open access: yesInternational Journal of Cancer, Volume 159, Issue 9, Page 2336-2346, 1 November 2026.
ABSTRACT The incidence of human papillomavirus‐positive (HPV+) oropharyngeal cancer (OPC) has increased rapidly, and HPV early antigen serology has been proposed as a scalable and cost‐effective early detection test. HPV seropositivity can precede clinical presentation of OPC by several years, so additional surveillance procedures may be necessary to ...

Clinical Validation of Four Point‐of‐Care High‐Risk HPV Assays, Including Two Reduced‐Valency Assays, for Cervical Cancer Screening in Low‐Resource Settings

open access: yesInternational Journal of Cancer, Volume 159, Issue 8, Page 2004-2014, 15 October 2026.
High‐risk human papillomavirus (hrHPV) testing improves cervical cancer screening by facilitating earlier detection and prevention. In low‐resource settings, however, cost and increased referrals limit its use. At the same time, many new and more affordable assays lack validation.
