Continuous serratus anterior block for sternotomy analgesia after cardiac surgery: a single-centre feasibility study.

Background: Moderate-to-severe pain is common after cardiac surgery, peaking during the first and second postoperative days. Several nerve blocks for sternotomy have been described; however, the optimal location for continuous catheters has not been established. This study assessed the feasibility of a larger trial evaluating the efficacy of serratus anterior plane (SAP) catheter analgesia for sternotomy pain.

Inulin Dehydration to 5-HMF in Deep Eutectic Solvents Catalyzed by Acidic Ionic Liquids Under Mild Conditions.

Valorization of carbohydrate-rich biomass by conversion into industrially relevant products is at the forefront of research in sustainable chemistry. In this work, we studied the inulin conversion into 5-hydroxymethylfurfural, in deep eutectic solvents, in the presence of acidic task-specific ionic liquids as catalysts. We employed aliphatic and aromatic ionic liquids as catalysts, and choline chloride-based deep eutectic solvents bearing glycols or carboxylic acids, as solvents.

Emergence and Rising Prevalence of Artemisinin Partial Resistance Marker Kelch13 P441L in a Low Malaria Transmission Setting in Southern Zambia.

Increasing artemisinin partial resistance (ArtR) due to mutations in the gene encoding Kelch13 () protein in eastern Africa is of urgent concern, and mutations, such as P441L, continue to emerge. We used an amplicon deep-sequencing panel to estimate the prevalence of ArtR mutations in samples collected between 2018 and 2023 in southern Zambia. P441L was present in 30 of 501 samples (6%), and prevalence increased over time (0% to 7.

Multiple plastid losses within photosynthetic stramenopiles revealed by comprehensive phylogenomics.

Ochrophyta is a vast and morphologically diverse group of algae with complex plastids, including familiar taxa with fundamental ecological importance (diatoms or kelp) and a wealth of lesser-known and obscure organisms. The sheer diversity of ochrophytes poses a challenge for reconstructing their phylogeny, with major gaps in sampling and an unsettled placement of particular taxa yet to be tackled. We sequenced transcriptomes from 25 strategically selected representatives and used these data to build the most taxonomically comprehensive ochrophyte-centered phylogenomic supermatrix to date.
