Establishment of Human Formative Pluripotent Stem Cell‐Like Cells Exhibiting Amniotic Differentiation Potentials

open access: yesCell Proliferation, EarlyView.
The hfPSC‐LCs could be established from naïve hESCs, conventional hESCs, hiPSCs, and human blastocysts. The hfPSC‐LCs hold robust capacity for three germ layers, hPGCLCs, and hALPCs. ABSTRACT Human embryos undergo pivotal morphogenetic remodelling shortly after implantation. The understanding of this crucial stage is severely impeded by the scarcity of

The Political U: New Evidence on the Economic Costs of Hybrid Regimes

open access: yesEconomics &Politics, EarlyView.
ABSTRACT Recent research establishes a positive causal effect from democracy to income, although this evidence relies mostly on binary regime classifications. We extend the identification framework of Acemoglu et al. (2019) to a classification that distinguishes democracies, autocracies, and hybrid regimes for about 170 countries over 1960–2024.

Inducible tomato defences persist in detached leaves, despite differential plant variety and gene‐dependent expression

open access: yesEcological Entomology, EarlyView.
Short‐ and long‐term expression of PPO‐D, PI‐IIc and PR‐1a were assessed in intact plants and detached tomato leaves of two varieties infested with Tetranhycus urticae. Tomato defences were induced in both intact and detached leaves, but the induction levels varied with plant variety and gene assessed.

Alteration in oral and non‐oral tissues in ligature‐induced periodontitis mice with the Alzheimer's disease risk factor APOE4

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract The APOE4 gene, particularly the ε4 allele, is linked to susceptibility to Alzheimer's disease, and periodontitis can cause pathological changes in multiple organs, but combined effects of these conditions and the impact of tumor necrosis factor (TNF)‐α regulation on the combined effects remain unclear.

H2‐dependent modulation of tetrahydromethanopterin S‐methyltransferase (Mtr complex) activity by the small protein MtrR in Methanosarcina mazei

open access: yesThe FEBS Journal, EarlyView.
Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...
