AI Article Synopsis
- Conventional solvents for extracting active ingredients require energy-intensive evaporation, impacting health and the environment.
- Switchable hydrophilic solvents (SHS) using amines and water offer a greener alternative, allowing for efficient extraction without the need for evaporation.
- The paper reviews the research on amine-based SHS, covering extraction mechanisms, influencing factors, and potential improvements for future applications.
Article Abstract
When conventional solvents such as water, methanol, ethanol, hexane, petroleum ether, etc., are used to extract active ingredients from natural resources, an evaporation process is required to remove solvent from active ingredients, which not only consumes huge amounts of energy, but also causes harm to human health and the environment. The CO-responsive switchable hydrophilic solvent (SHS) based on amines and water is an emerging, green and recyclable solvent, which not only has high extraction efficiency of active ingredients, but also can remove solvent from active ingredients without evaporation process. This paper reviews the research progress of amine-based SHS in the extraction of bioactive ingredients from natural resources. The process flow, extraction mechanism, critical influencing factors, recovery of amines and latest applications have been summarized. On this basis, some shortcomings of amine-based SHS are also pointed out. Finally, the improvement directions of amine-based SHS extraction in the future is prospected.

Alopecia, a common dermatological condition, poses significant psychological and social challenges. Despite the availability of various treatments, their efficacy is often limited by poor bioavailability and delivery challenges. Nanostructured lipid carriers have emerged as promising advanced drug delivery systems for alopecia treatment due to their ability to encapsulate both hydrophilic and lipophilic compounds, enhancing their stability, solubility, and controlled release.

Clavibacter michiganensis (Cmm), designated as an A2 quarantine pest by the European and Mediterranean Plant Protection Organization (EPPO), incites bacterial canker of tomato, which presently eludes rapid and effective control methodologies. Dense biofilms formed by Cmm shield internal bacteria from host immune defenses and obstruct the ingress of agrochemicals. Even when agrochemicals disintegrate biofilms, splashing and bouncing during application disperse active ingredients away from target sites.

Introduction: Group Interpersonal Therapy (IPT), an evidence-based treatment of depression recommended by the WHO mhGAP Intervention Guide, was implemented through a task-shifting approach in Senegal, as a treatment for depressed people living with HIV (PLWH). Since a description of the resources used and the implementation costs incurred is necessary to inform policymakers better, this study aimed to estimate the costs associated with its implementation.
Methods: Intervention costs were analyzed using an "ingredients-based costing approach" from the provider's perspective.

In addition to the known therapeutic indications for cannabidiol, its administration by inhalation appears to be of great interest. Indeed, there is evidence of cannabidiol's efficacy in several physiological pathways, suggesting its potential for a wide range of applications for both local and systemic pulmonary administration like cancers. Significant advances in pulmonary drug delivery have led to innovative strategies to address the challenges of increasing the respirable fraction of drugs and standardizing inhalable products.

Biostimulants are an emerging and innovative class of products that may mitigate the adverse effects of extreme heat, but research on their efficacy in fruit crops is limited. This study addressed this knowledge gap by evaluating the performance of three biostimulants, FRUIT ARMOR™, Optysil®, and KelpXpress™ [active ingredients glycine betaine, silicon, and kelp (Ascophyllum nodosum) extract, respectively] applied to three raspberry genotypes exposed to high temperatures (T ≥ 35 °C/day) inside a glasshouse. 'Meeker' consistently maintained high chlorophyll fluorescence (F/F) and photosynthesis under control and biostimulant treatments.
