In recent years, accelerating Chemistry, Manufacturing, and Controls (CMC) workflows for clinical entry has become a critical focus in biologics development. Advances in the development of cell lines, cell culture processes, and analytical technologies have enabled the generation of more homogeneous stable pool populations with increased productivity. Leveraging the experience gained from the COVID-19 product development, the strategic use of stable cell pools or a pool of clones for early-stage non-GMP material generation and process development has proven transformative in significantly reducing the CMC timeline to investigational new drug (IND). This study provides a comprehensive comparison of bioprocess performance and product quality attributes of materials produced from stable pools or a pool of clones (toxicology study materials) versus those from clonally derived cells (GMP clinical batches) across six First-in-Human (FIH) programs involving mAbs, bsAb, and Fc-fusion proteins. The results demonstrate a strong alignment and the feasibility of using protein materials from stable pools or a pool of clones in toxicology studies. In conclusion, utilizing non-clonal CHO cell-derived material for preclinical studies offers a strategic approach that can be broadly applied to complex molecules across various disease areas, even under standard regulatory filings, accelerating the path to clinical trials.

The activation energy (E) is the minimum energy necessary for (bio)chemical reactions acting as an energy barrier and defining reaction rates, for example, organic matter transformations in soil. Based on the E database of (i) oxidative and hydrolytic enzyme activities, (ii) organic matter mineralization and CO production, (iii) heat release during soil incubation, as well as (iv) thermal oxidation of soil organic matter (SOM), we assess the E of SOM transformation processes. After a short description of the four approaches to assess these E values-all based on the Arrhenius equation-we present the E of chemical oxidation (79 kJ mol, based on thermal oxidation), microbial mineralization (67 kJ mol, CO production), microbial decomposition (40 kJ mol, heat release), and enzyme-catalyzed hydrolysis of polymers and cleavage of mineral ions of nutrients (33 kJ mol, enzyme driven reactions) from SOM.

The rate of intramuscular phosphocreatine (PCr) depletion and recovery in response to exercise estimated from P MRS is an established measure for oxidative capacity. The creatine CH resonance in H MRS is known to exhibit a similar pattern. So far, repeating the exercise for consecutive H and P experiments posed limitations on the interpretation.

Understanding the organization and regulation of neurotransmission at the level of individual neurons and synapses requires tools that can track and manipulate transmitter-specific vesicles . Here, we present a suite of genetic tools in to fluorescently label and conditionally ablate the vesicular transporters for glutamate, GABA, acetylcholine, and monoamines. Using a structure-guided approach informed by protein topology and evolutionary conservation, we engineered endogenously tagged versions for each transporter that maintain their physiological function while allowing for cell-specific, bright, and stable visualization.

Lakes are hotspots for carbon and nitrogen cycling and a major contributor to the natural fluxes of greenhouse gases [GHGs: methane (CH), carbon dioxide (CO), and nitrous oxide (NO)] to the atmosphere. Lake volume reduction and salinization are major threats to lakes across the globe, and their effect on lake biogeochemistry warrants detailed investigation. Given the majority of the studies addressing this crisis are from the higher latitudes, the response of tropical lakes, and shallow lakes in particular, to changing magnitude of environmental stressors is a major research gap.

Climate change and intensive farming have caused soil degradation and decreased organic carbon stocks. Current research focuses on restoring soil fertility, often through organic amendments. Biosolids stabilized in constructed wetlands (CWs) may serve as an applicable organic amendment, although limited literature exists on their properties.
