Multimodal Imaging of Hypoxia, Metabolism and pH in Feline Sarcoma Using Hyperpolarized 13C MRI and PET

Advanced Science, EarlyView.
This work presents a clinically deployable simultaneous PET/MRI workflow which integrates hyperpolarized 13C imaging of metabolism and extracellular pH with [18F]FMISO PET to characterize hypoxia, acidosis, and metabolic reprogramming in feline sarcoma.

Granzyme B PET Imaging Reveals Lgmn+ Macrophage‐Mediated Immune Evasion and Guides Immunotherapy in EGFR‐TKI‐Resistant NSCLC

Advanced Science, EarlyView.
Graphical illustration of 68Ga‐GZB PET/CT imaging reveals immune dynamics post‐EGFR‐TKI resistance in NSCLC; Lgmn+ macrophages‐derived Lgmn‐containing extracellular vesicles inhibit glycolysis, induce CD8+ T cell exhaustion, and targeting Lgmn restores immunotherapy sensitivity.

Limited Agreement Between Perceptual and Physiological Heat Strain at Initial Stay Times for Continuous Work in the Heat Before Heat Alleviation Controls

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Accurate assessment of heat strain at initial stay time (IST; core temperature 38.0°C or Δ1.0°C above resting), when heat mitigation decisions are required, is critical for managing occupational heat exposure. We evaluated the relationship and agreement between physiological (Physiological Strain Index [PSI] and adaptive PSI [aPSI]

Giovanni Antonio Scopoli's De Hydrargyro Idriensi Tentamina (1761): Mercury Mining, Mercurialism, and Preventive Reasoning in Eighteenth‐Century Occupational Medicine

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Giovanni Antonio Scopoli (1723–1788), a physician‐naturalist of the Enlightenment, is primarily remembered for his contributions to botany and entomology. Less attention has been paid to his medical work De hydrargyro Idriensi Tentamina physico‐chymico‐medica (1761), written during his fifteen years of service as physician at the mercury mines

Timing of Work‐Rest Implementation Influences Worker Productivity Under Heat Stress: Evidence for Initial Stay Time‐Based Scheduling

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Work‐rest allocations recommended by the American Conference of Governmental Industrial Hygienists (ACGIH) limit heat strain and are typically implemented from the onset of work. Whether delaying implementation until after the initial stay time (IST; the duration of continuous work before core temperature reaches 38.0°C) improves ...
