Published: February 2014

A mild and general alkylation of terminal alkynes with transient σ-alkylpalladium(II) complexes for assembling alkyl-substituted alkynes is described. This method represents a new way to the use of transient σ-alkylpalladium(II) complexes in organic synthesis through 1,2-carboalkynylation of alkenes.

Metal ions are essential for all life. In microbial cells, potassium (K) is the most abundant cation and plays a key role in maintaining osmotic balance. Magnesium (Mg) is the dominant divalent cation and is required for nucleic acid structure and as an enzyme cofactor.

Efficient recombinant protein production requires mammalian stable cell lines or often relies on inefficient transfection processes. Baculoviral transduction of mammalian cells (BacMam) offers cost-effective and robust gene transfer and straightforward scalability. The advantages over conventional approaches are, no need of high biosafety level laboratories, efficient transduction of various cell types and transfer of large transgenes into host cells.

The plasticity of plant cells underlies their wide capacity to regenerate, with increasing evidence in plants and animals implicating cell-cycle dynamics in cellular reprogramming. To investigate the cell cycle during cellular reprogramming, we developed a comprehensive set of cell-cycle-phase markers in the Arabidopsis root. Using single-cell RNA sequencing profiles and live imaging during regeneration, we found that a subset of cells near an ablation injury dramatically increases division rate by truncating G1 phase.

Animal venom contains ion channel-targeting peptide toxins that inflict paralysis or pain. The high specificity and potency of these toxins for their target ion channels provides enticing opportunities for their deployment as tools in channel biology. Mechanistic studies on toxin-mediated ion channel modulation have yielded landmark breakthroughs in our understanding of channel architectures and gating mechanisms.

Given the complexities of continuous bioprocessing, it is critical to thoroughly investigate the process parameters unique to multi-column chromatography (MCC) and their potential impacts. However, existing studies have focused on either loading densities or residence time at steady states only, and their combined impact on critical quality attributes (CQAs) especially during transient phases were less known. In this study, we investigated the impact of critical process parameters during both steady-state and transient phases (start-up, close-down, and intermediate perturbation) through full factorial design.
