Vasopressin is becoming a widely used pressor in conditions with severe hypotension. Like several other hormones important in cardiovascular and extracellular fluid control, however, vasopressin can activate several receptors that when pharmacologically or pathologically stimulated may result in conflicting effects. In the present issue of Critical Care, Rehberg and colleagues examined the hypothesis that blockade of vasopressin V2 receptor during septic shock may be beneficial. Their tantalizing results indicate that future work must consider the precise vasopressin receptors that are stimulated and/or inhibited.

Mechanistic Insight into the Photoinduced Decarboxylative Radical Addition of Carboxylic Acid to Alkenes in a Two-Molecule Photoredox System.

The detailed mechanism of photoinduced decarboxylative radical addition to alkenes using both the effect of an electron donor (ED)/electron acceptor (EA) and laser flash photolysis in a two-molecule photoredox system was investigated. The concentration of EA played an important role in the photoreaction and could be controlled by varying the concentrations of ED/EA and their identity, which influenced Δ. Higher concentrations of ED/EA and a larger negative Δ led to a higher concentration of EA, thereby increasing the yield of the adduct; however, the large negative Δ for the generation of the EDA complex hindered decarboxylation.

Building DNA constructs of increasing complexity is key to synthetic biology. Golden Gate (GG) methods led to the creation of cloning toolkits - collections of modular standardized DNA parts hosted on hierarchic plasmids, developed for yeast, plants, Gram-negative bacteria, and human cells. However, Gram-positive bacteria have been neglected.

Aims: Mycobacterium tuberculosis (Mtb) remains a major global health challenge, particularly due to increasing drug resistance. Beyond the well-characterized mutations, the mechanisms involved in driving resistance appear to be more complex. This study investigated the differential gene expression of Ethiopian drug-resistant Mtb sub-lineage 4.

Background: Creatinine is a small molecule disease biomarker that reflects kidney function, accurate and effective detection of creatinine will play an important role in the prevention and treatment of diseases. Currently, commonly used creatinine detection methods are limited by expensive instruments, complex sample preparation, many interference factors from biological samples, and environmental factors that can affect the accuracy of the measurement. Therefore, developing a fast, simple, inexpensive, sensitive analysis method that can eliminate background interference and provide multi-detection modes has strong attraction and value.

Background: Perfluorooctane sulfonate (PFOS) is a persistent organic pollutant with significant risks to ecosystems and human health. Magnetic molecularly imprinted polymers (MIPs) provide a promising solution for selectively extracting PFOS from contaminated water. However, while bifunctional monomer imprinting improves the imprinting effect by introducing diverse functional groups, it can also increase non-specific adsorption.
