Chimpanzee naive pluripotent stem cells (PSCs) can now be grown in cellular cultures, reveals a recent study. They successfully created chimpanzee early embryo models, called ‘blastoids,’ and found that the inhibition of a specific regulatory gene is essential for chimpanzee PSC self-renewal. They also developed a feeder-free culture system, eliminating the need for mouse-derived feeder cells as support. These findings provide valuable insights into primate embryology and could advance stem cell research and regenerative medicine.
Current risk assessment guidelines for ischemic stroke may underestimate patients with mild carotid stenosis. A Japanese multicenter study found that unstable plaque—particularly intraplaque hemorrhage—was a key stroke predictor. Surgical intervention, such as carotid endarterectomy, significantly reduced stroke risk compared to medical therapy alone. These findings could prompt a shift in how physicians assess and treat mild but symptomatic carotid artery disease.
Cationic Ir(III) complex bound to synthetic saponite was used as a donor for TTA-UC(Triplet-triplet annihilation up-conversion)with 9,10-diphenylanthracne.
High quantum yield of TTA-UC was attained due to the hybridization with organically modified synthetic saponite in R-limonene.
Since R-limonene is a natural product belonging to a green solvent, the present finding may promise the possible utility of clay minerals for TTA-UC in green solvents.
