Based on a "transition metal frustrated Lewis pair" approach, a cyclopentadienone iron tricarbonyl complex has been designed and applied in the reductive amination and hydrogenation of bicarbonate. This well-defined phosphine-free complex displays the best activities reported to date for an iron complex in the reduction of bicarbonate into formate and in reductive amination.

Objective: to perform a cost-effectiveness analysis of asthma treatment with budesonide/formoterol against other treatment options used at Mexico's National Institute for Respiratory Diseases.
Methods: A complete economic evaluation of cost-effectiveness from a public health perspective, comparing the use of budesonide/formoterol as maintenance therapy with fluticasone/vilanterol in 103 female asthma patients managed at INER between 2015 and 2021.
Results: Average cost per patient was $743.

Skeletal muscle relaxants have their place in everyday use in numerous anesthesiological procedures, such as preparing a patient for surgery, supporting mechanical ventilation, and performing effective intubation. These drugs can be divided, based on their mechanism of action, into depolarizing skeletal relaxants, such as succinylcholine, and non-depolarizing skeletal muscle relaxants. Non-depolarizing agents are further categorized, based on their structure, into steroidal (eg, rocuronium) and benzylisoquinoline (eg, atracurium) compounds.

We herein report a microwave-assisted Buchwald-Hartwig double amination reaction to synthesize potential thermally activated delayed fluorescence compounds, forming C(sp)-N bonds between donor and acceptor units. Our approach reduces reaction times from 24 h to 10-30 min and achieves moderate to excellent yields, outperforming conventional heating methods. The method is compatible with various aryl bromides and secondary amines, including phenoxazine, phenothiazine, acridine, and carbazole.

Non-enzymatic glycation is the chemical reaction between the amine group of an amino acid and the carbonyl group of a reducing sugar. The final products of this reaction, advanced glycation end-products (AGEs), are known to play a key role in aging and many chronic diseases. The kinetics of the AGE formation reaction depends on several factors, including pH, temperature, and the presence of prooxidant metals, such as iron and copper.

Crystal violet (CV) is a disinfectant and antifungal agent used in aquaculture that plays a vital role in treating aquatic diseases and sterilizing water. However, its potential for strong toxicity, including carcinogenicity and mutagenicity, upon accumulation in the body raises concerns regarding its safe use. Therefore, there is a growing need for the quantitative detection of CV in its early application stages to ensure human safety.
