Suppression of TGF-β/SMAD signaling by an inner nuclear membrane phosphatase complexCytokines 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.

Identifying High-Risk Bacteria with Active Nasal Swab Surveillance in Intensive Care Units to Prevent Ventilator-Associated PneumoniaActive nasal surveillance culture (ANSC) is recognized to enable rapid detection of antibiotic-resistant bacteria in the intensive care unit (ICU), which can contribute to the prevention of Ventilator-associated pneumonia (VAP). This study aims to evaluate the usefulness of ANSC in assessing the development of VAP in ICU patients.

Climate change policies fail to protect child healthNational policies are essential for countries to adapt to the negative health impacts of climate change. Children are disproportionately affected by these impacts and must be at the heart of adaptation policies to address their vulnerabilities. Adaptation commitments worldwide are integrated into national adaptation plans, nationally determined contributions, national communications, and other multisectoral policies. We aimed to evaluate how effectively national climate change policies worldwide plan to protect child health, considering a range of determinants for successful child-health adaptation.

Sex assigned at birth may modify health-related quality of life in children treated with peanut oral immunotherapyThe high burden of peanut allergy underscores the need for treatment options that improve patient health-related quality of life (HRQL). However, the modifying effect of sex assigned at birth on treatment-related outcomes remains poorly understood. We sought to investigate whether sex modifies treatment effect on the change in overall and subdomain HRQL during the PPOIT-003 trial.

Phage cocktail amikacin combination as a potential therapy for bacteremia associated with carbapenemase producing colistin resistant Klebsiella pneumoniaeThe increasing occurrence of hospital-associated infections, particularly bacteremia, caused by extensively drug-resistant (XDR) carbapenemase-producing colistin-resistant Klebsiella pneumoniae highlights a critical requirement to discover new therapeutic alternatives. Bacteriophages having host-specific bacteriolytic effects are promising alternatives for combating these pathogens.

Early moderate prenatal alcohol exposure and maternal diet impact offspring DNA methylation across speciesAlcohol consumption in pregnancy can affect genome regulation in the developing offspring but results have been contradictory. We employed a physiologically relevant murine model of short-term moderate prenatal alcohol exposure resembling common patterns of alcohol consumption in pregnancy in humans.

Development and validation of a miniaturized bacteriophage host range screening assay against antibiotic resistant Pseudomonas aeruginosaAntimicrobial resistance is a current global health crisis, and the increasing emergence of multidrug resistant infections has led to the resurgent interest in bacteriophages as an alternative treatment.

Pseudomonas aeruginosa Resistance to Bacteriophages and Its Prevention by Strategic Therapeutic Cocktail FormulationAntimicrobial resistance poses a significant threat to modern healthcare as it limits treatment options for bacterial infections, particularly impacting those with chronic conditions such as cystic fibrosis (CF). Viscous mucus accumulation in the lungs of individuals genetically predisposed to CF leads to recurrent bacterial infections, necessitating prolonged antimicrobial chemotherapy. Pseudomonas aeruginosa infections are the predominant driver of CF lung disease, and airway isolates are frequently resistant to multiple antimicrobials.
One way the Wal-yan Respiratory Research Centre provides the opportunity for consumers and community members to contribute to our research is through participation in one of our eight community reference groups.
Focusing on the developmental trajectories of respiratory health includes developing strategies to improve and support immune system function and development over the life course.
