Development, validation and application of an LC-MS/MS method quantifying free forms of the micronutrients queuine and queuosine in human plasma using a surrogate matrix approach

The paper develops and validates an LC-MS/MS method to quantify free queuine and queuosine in human plasma, finding no detectable Q but significant q levels with no gender difference.

Canary in the Forest? Tree mortality and canopy dieback of western redcedar linked to drier and warmer summer conditions

This study links increased tree mortality and canopy dieback in western redcedar to drier and warmer summer conditions using tree-ring analysis across coastal and interior populations.

Development of a mouse model for spontaneous oral squamous cell carcinoma in Fanconi anemia

This paper develops a mouse model of spontaneous oral squamous cell carcinoma in Fanconi anemia by combining Fanca gene knockout with conditional Trp53 deletion in oral mucosa.

Multiple particle tracking (MPT) using PEGylated nanoparticles reveals heterogeneity within murine lymph nodes and between lymph nodes at different locations

The paper uses PEGylated nanoparticles and multiple particle tracking to study lymph node interstitial properties, finding pore sizes smaller than previously thought and location-dependent diffusion.

Belgian endive-derived biostimulants promote shoot and root growth in vitro.

The paper shows Belgian endive root extracts promote shoot and root growth in Arabidopsis and Plectranthus, with water-soluble sugars and malate as key bioactive compounds.

Nutrient copper signaling promotes protein turnover by allosteric activation of ubiquitin E2D conjugases

This paper shows that copper signaling modulates protein turnover by allosterically activating ubiquitin E2D conjugases, linking copper levels to protein degradation and morphogenesis.

Evaluation of a polymeric composite bone filler scaffold for local antibiotic delivery to prevent Staphylococcus aureus infection in a contaminated bone defect

This paper evaluates a bone filler scaffold for local antibiotic delivery to prevent Staphylococcus aureus infection in contaminated bone defects, showing effective bacterial eradication and no adverse effects on osteogenic properties.

Divergence in a stress-associated gene regulatory network underlies differential growth control in the Brassicaceae family

The study identifies conserved and divergent ABA gene regulatory networks across Brassicaceae species, revealing how network structure influences growth control under stress.

Granzyme A inhibition reduces inflammation and increases survival during abdominal sepsis.

This study shows that inhibiting Granzyme A reduces inflammation and improves survival in abdominal sepsis by decreasing proinflammatory markers without affecting bacterial load.

Predictive engineering and optimization of tryptophan metabolism in yeast through a combination of mechanistic and machine learning models

This study combines mechanistic and machine learning models to optimize tryptophan metabolism in yeast, achieving a 106% increase in tryptophan accumulation through predictive engineering.
