Efficient water‐soluble blue/red‐emissive carbon dots matching plant absorption spectra: Synthesis, tunable control, and their applications in promoting plant growth

open access: yesResponsive Materials, EarlyView.
Guided by the spectral demand of plant photosystems, this review summarizes the synthesis, emission regulation, dual‐emission design, and gram‐scale production of CDs for agricultural applications. Spectrally matched blue‐ and red‐emissive CDs enhance plant light utilization by converting underutilized light into photosynthetically active radiation and

Cardiomyocyte Membrane‐Camouflaged Spinach Nano‐Thylakoids Enhance Myocardial Energy Metabolism and Ameliorate Heart Failure

open access: yesSmall, EarlyView.
Schematic illustration of the construction of MM‐NTU, its cardiac‐targeting behavior, and its light‐activated therapeutic mechanism. Thylakoids isolated from spinach chloroplasts were processed into nano‐thylakoid units (NTU) and further camouflaged with cardiomyocyte membranes to generate MM‐NTU.

Advances in research on layered double hydroxides for biomedical applications

open access: yesSmart Molecules, EarlyView.
Layered double hydroxides (LDHs) are pH‐responsive nanomaterials with broad biomedical applications. This review summarizes LDH synthesis methods and compares their advantages. It highlights LDHs' progress in cancer therapy, including chemo‐photothermal, chemo‐immunotherapy, and photodynamic‐immunotherapy combinations and their potential in bone repair.

Visualizing structural dynamics of thylakoid membranes [PDF]

open access: yes, 2014
To optimize photosynthesis, light-harvesting antenna proteins regulate light energy dissipation and redistribution in chloroplast thylakoid membranes, which involve dynamic protein reorganization of photosystems I and II.

Structural insights into θ‐type carbonic anhydrases 3 and 4: Tuning the directionality of CO2 hydration in a diatom

open access: yesThe FEBS Journal, EarlyView.
θ‐CA3 from a marine diatom has an N‐terminal transmembrane helix and two homologous catalytic domains. The enzyme functions as a dimer, with active sites formed near the dimer interface. A bicarbonate ion binds on the symmetry axis of the dimer and forms hydrogen bonds with both monomers, thereby activating θ‐CA3 and tuning CO2 hydration activity ...

Rescue of pATOM36‐depleted T. brucei by human MTCH1/2 reveals common features of protein insertases

open access: yesThe FEBS Journal, EarlyView.
Human MTCH1 and MTCH2 (with an N‐terminal extension) functionally complement the loss of pATOM36 in T. brucei, indicating that these evolutionarily distant proteins recognize a common set of substrates and share fundamental principles of mitochondrial outer membrane protein insertion. Structural analyses reveal a common hydrophilic cavity, supporting a

DnaK3 Is Involved in Biogenesis and/or Maintenance of Thylakoid Membrane Protein Complexes in the Cyanobacterium Synechocystis sp. PCC 6803

open access: yesLife, 2020
DnaK3, a highly conserved cyanobacterial chaperone of the Hsp70 family, binds to cyanobacterial thylakoid membranes, and an involvement of DnaK3 in the biogenesis of thylakoid membranes has been suggested. As shown here, light triggers synthesis of DnaK3

Advances in high‐resolution cryo‐volume electron microscopy (cvEM) imaging for unicellular and multicellular organisms

open access: yesJournal of Microscopy, EarlyView.
Abstract Cryo‐Focused Ion Beam Scanning Electron Microscopy (cryoFIB‐SEM) using samples fixed by high‐pressure freezing uniquely enables high‐resolution cryo‐volume Electron Microscope (cvEM) images of cell ultrastructure to be obtained from whole cells and complex tissues in their near native state. As the freezing process also preserves fluorescence,
