Mechanism and In Vitro Reconstitution of Mammalian Germ-Cell Development.

The germ-cell lineage ensures the creation of new individuals, perpetuating/diversifying the genetic and epigenetic information across the generations. We have been investigating the mechanism for germ-cell development, and have shown that mouse embryonic stem cells (mESCs)/induced pluripotent stem cells (miPSCs) are induced into primordial germ cell-like cells (mPGCLCs) with a robust capacity both for spermatogenesis and oogenesis and for contributing to offspring. These works have served as a basis for elucidating key mechanisms during germ-cell development such as epigenetic reprogramming, sex determination, meiotic entry, and nucleome programming.

Dynamic Modulation of Ions Solvation Sheath by Butyramide as Molecular Additives in Aqueous Batteries.

The high activity of water in aqueous battery electrolytes can trigger side reactions, limiting their large-scale application. Additives that form contact pairs (CPs) with cations by coordinating with them can effectively reduce water's activity. However, due to the complex interactions between ions, additives, and solvent molecules and the fact that current strategies for additive screening primarily rely on static physical parameters, the dynamic mechanisms that govern the modulation of ion solvation sheaths are still poorly understood.

Arketamine alleviates cognitive impairments and demyelination in mice with postoperative cognitive dysfunction via TGF-β1 activation.

Postoperative cognitive dysfunction (POCD) is characterized by a decline in cognitive functions, including memory, attention, and executive abilities, following surgery, with no effective therapeutic drugs currently available. Arketamine, the (R)-enantiomer of ketamine, has shown promise in mitigating cognitive deficits in animal models. In this study, we investigated whether arketamine could ameliorate cognitive deficits in a mouse model of POCD, with a focus on the role of transforming growth factor (TGF)-β1 in its effects.

Climate displaces deposition as dominant driver of dissolved organic carbon concentrations in historically acidified lakes.

Unlabelled: Climate and atmospheric deposition interact with watershed properties to drive dissolved organic carbon (DOC) concentrations in lakes. Because drivers of DOC concentration are inter-related and interact, it is challenging to assign a single dominant driver to changes in lake DOC concentration across spatiotemporal scales. Leveraging forty years of data across sixteen lakes, we used structural equation modeling to show that the impact of climate, as moderated by watershed characteristics, has become more dominant in recent decades, superseding the influence of sulfate deposition that was observed in the 1980s.
