Atomically precise metal cluster enzymes for pathological tissue regeneration
BMEMat, EarlyView.Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

BMEMat, EarlyView.Studies reveal that a biomimetic nanoplatform based on a cancer cell membrane‐camouflaged Au‐MnOx nanozyme (Au‐MnOx@CCM) can achieve synergistic antitumor therapy by combining NIR‐II mediated PTT with enhanced CDT, offering a promising strategy for precise and efficient tumor therapy. Abstract The therapeutic potential of nanozyme‐mediated chemodynamic

BMEMat, EarlyView.Inorganic sonosensitizers suffer from inefficient electron‐hole separation, rapid recombination, and wide bandgaps in anti‐fungal applications. We propose MN@Fe2N/CeO2 to directly eliminate fungi without drug resistance. Combining semiconductor CeO2's advantages with Fe2N's high work function and activity enables efficient Schottky heterojunctions ...

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora
Biological Reviews, EarlyView.ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

The lower amount of 5 methylcytosine in DNA from bull sperm relative to DNA of other bovine tissues is a result of the absence of this minor base from several of the satellite DNAs in sperm. This applies particularly to the 1.715, 1.711b and 1.709 satellites and less so to the 1.706 and 1.711a satellites.

Satellite DNAs represent the most abundant fraction of repetitive sequences in genomes of almost all eukaryotic species. Long arrays of satellite DNA monomers form densely packed heterochromatic genome compartments and also span over the functionally important centromere locus.

Nuclear satellite DNAs of yeast
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1972High molecular weight DNA isolated from yeast nuclei has been fractionated in Ag+-Cs2SO4 and Hg2+-Cs2SO4 density gradients. Centrifugation in Ag+-Cs2SO4 gradients resulted in the appearance of a satellite band on the heavy side of the gradients. This satellite DNA, which accounts for 3–5 % of the total DNA, does not code for either 26-S, 17-S and 5 ...

The mystery of how satellite DNA came to be so widespread in plants and animals could be solved if this DNA conferred an advantage on the chromosome which carried it. This advantage might be an improved ability to stand up to the rigours of meiosis.
