Age‐associated immune dysregulation links to disease severity in macrolide‐resistant Mycoplasma pneumoniae pneumonia: Insights from a comparative juvenile–adult mouse model

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Macrolide‐resistant Mycoplasma pneumoniae (MRMP) infected both juvenile and adult mice, with results compared to normal juvenile mice. The findings revealed comparable bacterial loads between juvenile and adult mice, yet juvenile mice exhibited more severe lung damage and elevated levels of inflammatory cytokines.

Cooling Holes in Polymer Spur Gears: A Critical Analysis of Heat Dissipation Benefits and Mesh Stiffness Penalties

open access: yesJournal of Applied Polymer Science, EarlyView.
Cooling holes provide a simple passive cooling strategy for polymer spur gears, reducing maximum operating temperature by up to 9.39% while introducing a measurable gear mesh stiffness penalty. A validated response‐surface model reveals how hole size and location govern this thermal–mechanical trade‐off, enabling design optimization for thermally and ...

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton

open access: yesThe Anatomical Record, EarlyView.
Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

Multi‐Omic Profiling Reveals Immune Cell Priming Signature Linked to Lupus Prognosis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Systemic lupus erythematosus (SLE) is a multiorgan disease with widespread immune dysregulation and significant unmet clinical need. Blood‐based gene expression studies have advanced our understanding of SLE pathogenesis but may overlook critical tissue‐specific mechanisms that drive disease heterogeneity and progression.
