Imaging and genetic toolbox to study Arabidopsis embryogenesis

New Phytologist, EarlyView.
Summary Embryogenesis in the model plant Arabidopsis thaliana provides a framework for understanding how cell polarity and patterning coordinate with hormonal signalling to establish the plant body plan. Following fertilisation, the zygote divides asymmetrically to generate apical and basal lineages, establishing the apical–basal axis that defines ...

Statistical Shape Modeling of the Clavicle: Morphological Variation, Sex Differences, and Surgical Implications

Orthopaedic Surgery, EarlyView.
In 288 Asian adult clavicles, the first six PCA modes explained 82.38% of shape variance. Morphology showed significant sex differences without side asymmetry, and data‐driven clustering poorly matched the traditional three‐type scheme, supporting individualized planning and implant design.

Physiological cerebrospinal fluid interactions between brain and eye structures are altered after long‐duration spaceflight

Experimental Physiology, EarlyView.
Abstract Long‐duration spaceflight represents an extreme challenge, triggering adaptive responses including spaceflight‐associated neuro‐ocular syndrome, characterized by diminished visual acuity and ocular changes, which is a significant health risk for Mars missions.

Utility of local capillary supply indices: Insights from computational image‐based modelling

The Journal of Physiology, EarlyView.
Abstract figure legend Local capillary distribution and fibre geometry influence oxygen availability in skeletal muscle. Image‐based modelling of tissue PO2${{P}_{{{{\mathrm{O}}}_2}}}$ shows that area‐based measures of capillary supply – the local capillary density (LCDi) and local maximum diffusion distance (Dmax,i) – most accurately represent the ...
