Summary: Lichenan-decorated selenium nanoparticles (L-SeNPs) with good water dispersibility were prepared. These L-SeNPs exhibited orange-red, amorphous, zero-valent, and uniform spherical nano-particles with an average diameter of 96 nm. The surface modification of SeNPs with lichenan endowed the L-SeNPs with superior antioxidant capability and excellent selenium controlled-release performance.

Summary: Forest canopies play a crucial role in modifying microclimates and providing habitats for nonvascular epiphytes. This study examines the mechanisms regulating the vertical and horizontal distributions of Usnea longissima, the world's longest lichen, in old-growth forests. The 3D distribution of the lichen is influenced by canopy structure, light environment, and various functional mechanisms. Understanding these factors is important for the conservation and management of lichens in forest canopies.

Summary: The objective of this study was to identify and characterize compounds from Usnea longisssimia. The lichen thallus was extracted with different polarity solvents to evaluate phytochemicals and the yield of the extracts was quantified. Chemical markers were identified using preparative TLC and characterized through FTIR spectroscopy. Usnic acid was identified as a major marker along with Barbatic acid, Diffractaic acid, Divaricatic acid, and Fumarprotocetraic acid, respectively. The yield of usnic acid was found to be highest in ethanol, ranging from 1.84% to 5.06%. This study highlights the impact of polarity-based extraction on extract yield and specific compound isolation.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
