Anthropogenic activities are increasing the amount of carbon dioxide (CO2) in the atmosphere. There is mounting experimental evidence that lifetime exposure to these increasing atmospheric CO2 levels can negatively impact the normal physiology of organisms. However, directly assessing this in humans is very difficult.
Cytokines of the TGF-β superfamily control essential cell fate decisions via receptor regulated SMAD (R-SMAD) transcription factors. Ligand-induced R-SMAD phosphorylation in the cytosol triggers their activation and nuclear accumulation. We determine how R-SMADs are inactivated by dephosphorylation in the cell nucleus to counteract signaling by TGF-β superfamily ligands.
Respiratory infection and wheezing illness are leading causes of hospitalisation in childhood, placing a significant burden on families and healthcare systems. However, reliably distinguishing children at risk of developing persistent disease from those likely to outgrow their symptoms remains a clinical challenge. Earlier identification would allow clinicians to focus care and resources on those most likely to benefit from long-term management, while reducing anxiety and uncertainty about the future for families.
Avian influenza viruses (AIVs) pose a growing global health threat, particularly in low- and middle-income countries (LMICs), where limited surveillance capacity and under-resourced healthcare systems hinder timely detection and response. Migratory birds play a significant role in the transboundary spread of AIVs, yet data from key regions along migratory flyways remain sparse. To address these surveillance gaps, we conducted a study between December 2021 and February 2023 using fresh bird guano collected across 10 countries in the Global South.
We report the isolation of a bacteriophage with obligately lytic activity against Pseudomonas aeruginosa from wastewater. The reported phage, Minga-mokiny 4, appears to belong to the Schitoviridae family, is of the Litunavirus genus, and has a 72,362-bp genome. No known genes associated with lysogeny, bacterial resistance, or virulence were predicted.
