Tissue clearing for whole organ cell profiling has revolutionized biology and imaging for exploration of organs in three-dimensional space without compromising tissue architecture. But complicated, laborious procedures, or expensive equipment, as well as the use of hazardous, organic solvents prevents the widespread adoption of these methods. Here we report a simple and rapid tissue clearing method, EZ Clear, that can clear whole adult mouse organs in 48 hours in just three simple steps. Samples stay at room temperature and remain hydrated throughout the clearing process, preserving endogenous and synthetic fluorescence, without altering sample size. After wholemount clearing and imaging, EZ Cleared samples can be further processed for downstream embedding and cryosectioning followed by standard histology or immunostaining, without loss of endogenous or synthetic fluorescence signal. Overall, the simplicity, speed, and flexibility of EZ Clear make it easy to adopt and apply to diverse approaches in biomedical research.

Aims: We investigated the influence of dust pollution on stomatal conductance and photosynthetic pigments in some medicinal plants growing at Lokpa Ukwu quarry site, Abia State, Nigeria. Place and Duration of Study: Samples were collected from Lokpa Ukwu, Abia State while laboratory analyses were carried out in the Department of Pharmacognosy and Environmental Medicines, University of Nigeria, Nsukka between February and April, 2019. Methodology: A total of nine (9) plants were sampled for the study. Leaf epidermises were prepared by clearing method and stomata were observed and studied quantitatively. Stomatal conductance was estimated from the anatomical variables following standard procedures. Total chlorophyll and β-carotene contents were also analysed and compared with control groups. Results: We observed some physiological changes in the plants from dust-polluted site such as stretched epidermal cells, deformed stomata and plasmolysed guard cells. It reduced the potential conductance indices (PCI) of the plants by 87.4% in Aspilia africana and 67% in Chromolaena odorata. The least reduction in PCI was observed in Celosia trigyna (7.2%). Operating conductance (gop) and maximum conductance (gmax) were reduced by 69.2% and 72.3% in C. odorata and A. africana respectively. Celosia trigyna was least affected with percentage reductions of 18.3% and 1.4% for gop and gmax respectively. Reduction in PCI and gmax followed the order: C. trigyna ˂ C. papaya ˂ P. discoideus ˂ D. oliveri ˂ T. rhomboidea ˂ T. orientalis ˂ V. doniana ˂ C. odorata ˂ A. africana. Total chlorophyll and β-carotene contents were reduced the most in V. doniana (45.73%) and C. odorata (40.31%) respectively and least reduced in T. orientalis by 19.54% and 13.24% respectively. Conclusion: Our findings validate previous reports of negative effects of dust pollution from quarry industries on both humans and plants alike.
