A new study led by U of T researchers finds that post-surgical recovery time in older adults is much longer than expected, with data showing nearly 20 per cent still have impairments in activities of daily living.
Researchers at the MDI Biological Laboratory have identified how zebrafish regenerate and reconnect new kidney filtration units after injury, revealing a coordinated cellular process that allows newly formed nephrons to integrate into the kidney’s existing tubule network. The study, published in the journal Development, shows that specialized cells at the connection site briefly adopt invasive behaviors—extending protrusions that initiate the physical link between new and old structures—while neighboring cells simultaneously divide and expand the growing tubule. The work also identifies intersecting signaling pathways, including canonical and non-canonical branches of Wnt signaling mediated by the receptor fzd9b, that orient the connection and regulate cell behavior. Understanding how zebrafish achieve this precise integration may help researchers overcome a major obstacle in regenerative medicine: enabling lab-grown tissues and organoids to connect into existing organs and become fully functional.
Scientists from University of Louvain and the Cliniques universitaires Saint-Luc have discovered the protective role of a bacterium that could prevent long Covid
The bacterium is less abundant in the nasopharynx of individuals who develop symptoms that persist over time, offering a potential avenue for the development of a probiotic administered as a nasal spray
With nearly 400 million sufferers worldwide from long Covid, this major finding, published in Microbiology Spectrum, addresses a genuine public health issueMeasures of blood vessel health derived from routine blood pressure readings may help identify adults at increased risk for dementia, according to research being presented at the American College of Cardiology’s Annual Scientific Session (ACC.26). The findings from two studies that tracked patterns of arterial stiffness over time align with growing evidence that uncontrolled hypertension contributes to the development of dementia by accelerating the aging and stiffening of blood vessels.
