Comparison of sugars, iridoid glycosides and amino acids in nectar and phloem sap of Maurandya barclayana, Lophospermum erubescens, and Brassica napus. [PDF]
PLoS ONE, 2014 BACKGROUND: Floral nectar contains sugars and amino acids to attract pollinators. In addition, nectar also contains different secondary compounds, but little is understood about their origin or function. Does nectar composition reflect phloem composition,

Synthesis of rare sugars via epimerization catalyzed by tin-organic frameworks
Current Research in Green and Sustainable ChemistryEpimerization of readily available monosaccharides presents an atom-efficient approach to expand the portfolio of rare monosaccharides. Here, we report tin-organic frameworks (Sn-OF) as a highly selective catalyst for synthesis of rare monosaccharides ...

Advanced Science, EarlyView.Cytokine‐engineered CAR‐T cells represent a promising immunotherapy against malignancies due to direct tumor killing and potent immunity response. However, significant toxicities, including CRS and ICANS, have restricted clinical applications. How to keep the risk‐benefit balance of the advanced therapy is of great importance for maximizing the benefit

Spiral Galaxies as Enantiomers: Chirality, an Underlying Feature in Chemistry and Astrophysics
, 2005 Spiral galaxies are axi-symmetric objects showing 2D-chirality when projected onto a plane. Features in common with tetrahedral molecules are pointed out, in particular the existence of a preferred chiral modality for genetic galaxies as in aminoacids ...

Forager bees (Apis mellifera) highly express immune and detoxification genes in tissues associated with nectar processing. [PDF]
, 2015 Pollinators, including honey bees, routinely encounter potentially harmful microorganisms and phytochemicals during foraging. However, the mechanisms by which honey bees manage these potential threats are poorly understood.
