Article Synopsis
  • Glycemic variability (GV) is a common issue in critically ill patients, and this study explored its impact on 28-day mortality through a multicenter analysis involving 578 patients across five ICUs in Turkey.
  • The study tracked several glycemic parameters within the first 24 hours, finding significant differences in CV (coefficient of variation), SD (standard deviation), and MGD (maximal-minimal glucose difference) between survivors and non-survivors, with higher levels linked to increased mortality risk.
  • Results indicated that CV is an independent risk factor for mortality, with a strong correlation with MGD, suggesting that monitoring these glycemic metrics could be critical for predicting patient outcomes in intensive care settings.

Article Synopsis
  • Low serum magnesium levels are common in ICUs and may be linked to new-onset atrial fibrillation (NOAF), which is under-researched.
  • A study with 110 ICU patients found that those with NOAF had lower median magnesium levels and a higher rate of hypomagnesemia compared to a control group.
  • NOAF is associated with higher mortality in critically ill patients, with hypomagnesemia identified as an independent risk factor for developing NOAF and increased hospital mortality.

Pichia pastoris is one of the most widely used host for the production of recombinant proteins. Expression systems that rely mostly on promoters from genes encoding alcohol oxidase 1 or glyceraldehyde-3-phosphate dehydrogenase have been developed together with related bioreactor operation strategies based on carbon sources such as methanol, glycerol, or glucose. Although, these processes are relatively efficient and easy to use, there have been notable improvements over the last twenty years to better control gene expression from these promoters and their engineered variants.

Engineered promoters are key components that allow engineered expression of genes in the cell-factory design. Promoters having exceptional strength are attractive candidates for designing metabolic engineering strategies for tailoring de novo production strategies that require directed evolution methods by engineering with de novo synthetic biology tools. Engineered promoter variants (EPVs) of naturally occurring promoters (NOPs) can be designed using metabolic engineering strategies and synthetic biology tools if the genes encoding the activating transcription factors (TFs) exist in the genome and are expressed and synthesized at non-limiting concentrations within the cell.

Hybrid-architectured promoter design to deregulate expression in yeast under modulating power of carbon sources involves replacing native cis-acting DNA sequence(s) with de novo synthetic tools in coordination with master regulator transcription factor (TF) to alter crosstalk between signaling pathways, and consequently, transcriptionally rewire the expression. Hybrid-promoter architectures can be designed to mimic native promoter architectures in yeast's preferred carbon source utilization pathway. The method aims to generate engineered promoter variants (EPVs) that combine the advantages of being an exceptionally stronger EPV(s) than the naturally occurring promoters and permit "green-and-clean" production on a non-toxic carbon source.
