To accelerate the water dissociation in the Volmer step and alleviate the destruction of bubbles to the physical structure of catalysts during the alkaline hydrogen evolution, an integrated electrode of cobalt oxide and cobalt-molybdenum oxide grown on Ni foam, named CoO-Co2Mo3O8, is designed. This integrated electrode enhances the catalyst-substrate interaction confirmed by a micro-indentation tester, and thus hinders the destruction of the physical structure of catalysts caused by bubbles. Electrochemical testing shows the occurrence of a surface reconstruction of the integrated electrode, and CoO is transformed into Co(OH)2, denoted as Co(OH)2-Co2Mo3O8.

Modeling the response to interleukin-21 to inform natural killer cell immunotherapy.

Immunol Cell Biol

January 2025

Steve and Cindy Rasmussen Institute for Genomic Medicine, Abigail Wexner Research Institute, Nationwide Children's Hospital, Columbus, OH, USA.

Natural killer (NK) cells are emerging agents for cancer therapy. Several different cytokines are used to generate NK cells for adoptive immunotherapy including interleukin (IL)-2, IL-12, IL-15 and IL-18 in solution, and membrane-bound IL-21. These cytokines drive NK cell activation through the integration of signal transducers and activators of transcription (STAT) and nuclear factor-kappa B (NF-κB) pathways, which overlap and synergize, making it challenging to predict optimal cytokine combinations for both proliferation and cytotoxicity.

Theoretical and practical considerations for validating antigen-specific B cell ImmunoSpot assays.

J Immunol Methods

January 2025

Research & Development Department, Cellular Technology Limited, Shaker Heights, OH 44122, USA. Electronic address:

Owing to their ability to reliably detect even very rare antigen-specific B cells in cellular isolates such as peripheral blood mononuclear cells (PBMC), and doing so robustly in a high throughput-compatible manner, B cell ELISPOT/FluoroSpot (collectively "B cell ImmunoSpot") tests have become increasingly attractive for immune monitoring in regulated settings. Presently, there are no guidelines for the qualification and validation of B cell ImmunoSpot assay results. Here, we propose such guidelines, building on the experience acquired from T cell ImmunoSpot testing in an environment adhering to the requirements of regulatory bodies yet taking the unique features of B cell assays into account.

Department of Chemistry and Biochemistry, Ohio University, Athens, OH 45701, USA; Molecular and Cellular Biology Program, Ohio University, Athens, OH 45701, USA; Edison Biotechnology Institute, Ohio University, Athens, OH 45701, USA.

Somatic Y537S and D538G mutations within the estrogen receptor alpha ligand-binding domain (ERα-LBD) have been linked to enhanced cell proliferation, survival, and metastases in ER-positive breast cancers. Such mutations are thought to confer ligand-independent receptor activation by increasing the flexibility of helix 12 (H12), a segment within the ERα-LBD that acts as a dynamic regulator of ERα activity. We employed bipartite tetracysteine display coupled with the biarsenical profluorophore FlAsH-EDT to monitor ligand-independent structural transitions of H12 in ERα-LBDs that include Y537S or D538G mutations.

Department of Biology and Western Program, Miami University, Oxford, OH 45056, USA. Electronic address:

Hyphae are viscoelastic tubes whose internal pressure pushes the cell membrane against the inner surface of the cell wall. Catalytic yielding of the wall allows this turgor to force its polymers apart as new materials are added to the surface of the growing tip. Turgor drops slightly as the wall expands, creating a pressure gradient that causes the cytoplasm to flow toward the tip.
