Therapeutic Effects of 30 nm Cyclosporin A-Loaded Nanoparticles Using PLGA-PEG-PLGA Triblock Copolymer for Transdermal Delivery in Mouse Models of Psoriasis Open
This study aimed to evaluate the effectiveness of poly(DL-lactide-co-glycolide)-block-poly(ethylene glycol)-block-poly(DL-lactide-co-glycolide) triblock copolymers (PLGA-PEG-PLGA) as a drug carrier in the treatment of psoriasis. Nanopartic…

Novel provenance approaches for tracing Cedrela timber in Bolivia Open
Illegal logging and its related timber trade is one of the major drivers of forest loss, species diversity and economic and social conflicts. Over the last decades, several international and national regulations have been implemented as an…

Foliar water uptake as a source of hydrogen and oxygen in cellulose of vascular plants Open
Where do oxygen and hydrogen atoms of organic matter from terrestrial plant, such as O and H in cellulose, come from? We already know that O in cellulose originates from water within plants, instead of CO2 taken in via leaf stomata, and st…

Decadal trends in 137Cs concentrations in the bark and wood of trees contaminated by the Fukushima nuclear accident Open
Understanding the actual situation of radiocesium ( 137 Cs) contamination of trees caused by the Fukushima nuclear accident is essential for predicting the future contamination of wood. Particularly important is determining whether the 137…

Foliar water uptake as a source of hydrogen and oxygen in plant biomass Open
Introductory biology lessons around the world typically teach that plants absorb water through their roots, but, unfortunately, absorption of water through leaves and subsequent transport and use of this water for biomass formation remains…

Post-photosynthetic Carbon, Oxygen and Hydrogen Isotope Signal Transfer to Tree Rings—How Timing of Cell Formations and Turnover of Stored Carbohydrates Affect Intra-annual Isotope Variations Open
In this chapter, we discuss post-photosynthetic processes that affect intra-annual variation in the stable isotopes of tree rings, such as timing of cell formations and turnover of stored carbohydrates, by combining research findings gaine…

Temporal trends in 137Cs concentrations in the bark, sapwood, heartwood, and whole wood of four tree species in Japanese forests from 2011 to 2016 Open
To understand the changes in radiocesium (137Cs) concentrations in stem woods after the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident, we investigated 137Cs concentrations in the bark, sapwood, heartwood, an…

Reproduction-related variation in carbon allocation to woody tissues in<i>Fagus crenata</i>using a natural<sup>13</sup>C approach Open
The contribution of new photo-assimilates and stored carbon (C) to plant growth remains poorly understood, especially during reproduction. In order to elucidate how mast seeding affects C allocation to both reproductive and vegetative tiss…
