Background And Objectives: Following the development of nuclear chemistry with halogenate synthesis in the 50s of past century, several anesthetics were clinically studied and some of them had wide practical application. The search for the ideal agent continues. Currently, halothane, isoflurane, enflurane, sevoflurane and desflurane are in clinical use. All have advantages and disadvantages. Desflurane is the newest agent. This study aimed at describing physicochemical and pharmacological properties of desflurane and reporting clinical experiences with this agent.
Contents: Physicochemical properties and pharmacokinetic and pharmacodynamic properties of desflurane determine its clinical use. With a low boiling point, it volatizes easily in normal operating room temperatures and its high MAC requires it to be administered in high concentrations. So, the use of low fresh gas flow and special vaporizer is recommended for it to be economically feasible. In addition, the use of coadjuvant anesthetics, such as nitrous oxide, decreases its MAC and allows it to be used in lower concentrations. Its pharmacokinetics provides fast induction and recovery being also worth mentioning that it has a highly stable molecule and is minimally metabolized, thus being well tolerated by the human body. Its pharmacodynamic repercussions are dose-dependent and similar to other potent inhalation anesthetics.
Conclusions: Desflurane is an additional step in the evolution toward the ideal anesthetic agent. Its physicochemical properties give it highly desirable pharmacokinetic characteristics which provide fast induction (progression) and recovery and also minimal metabolic degradation with the lowest organic toxicity among halogenate anesthetics, in addition to strong molecular stability, even in the presence of carbon dioxide absorbents. With special attention regarding vaporization, storage, and consumption, desflurane may be used even in large scale, being economically feasible.

This paper presented the preparation, characterization, and adsorption properties of Brazil nut shell activated carbon for catechol removal from aqueous solutions. The equilibrium adsorption of catechol molecules on this activated was experimentally quantified at pH 6 and temperatures ranging from 25 to 55 °C, and at 25 °C and pH ranging from 6 to 10. These results were utilized to elucidate the role of surface functionalities through statistical physics calculations.

The defoliation quality of mugwort defoliation equipment is an important factor to measure the defoliation efficiency, and the tensile properties of mugwort petiole will have an impact on the defoliation quality, such as the crushing rate and the abscission rate. In order to reduce the crushing rate and improve the abscission rate during mechanical harvesting of mugwort leaves, the tensile properties of mugwort petiole need to be studied. The tensile properties of mugwort petiole are closely related to its macroscopic and microscopic physicochemical parameters.

Accurate prediction of drug-target binding affinity remains a fundamental challenge in contemporary drug discovery. Despite significant advances in computational methods for protein-ligand binding affinity prediction, current approaches still face substantial limitations in prediction accuracy. Moreover, the prevalent methodologies often overlook critical three-dimensional (3D) structural information, thereby constraining their practical utility in computer-aided drug design (CADD).
