When children and adolescents present to the emergency department with agitation or mental status changes, intoxication from synthetic drug use should be in the differential diagnosis. Identifying the responsible compound(s) may be difficult, so asking the patient broad questions and utilizing appropriate diagnostic studies, when indicated, will aid in making the diagnosis and help identify more-serious complications. This issue discusses the challenges presented by the changing chemical formulations of synthetic cannabinoids, cathinones, and phenethylamines; outlines common presentations of intoxication from these substances; and summarizes best practices for evaluating and managing patients who present with intoxication after consumption of these synthetic drugs of abuse.

Recent examples of immune responses directed against the synthetic polymer poly(ethylene glycol) (PEG) have led to the development of biocompatible polymers, which are viewed as promising candidates to act as surrogate materials for use in biological applications, such as hydrophilic poly(2-oxazoline)s (POx). Despite this, the characterization of critical aspects of the immune response against these emerging materials is sparse, in part because no known monoclonal antibodies (mAbs) against this family of synthetic material have been reported. To advance the understanding of such responses, we report the successful isolation and characterization of hybridoma-derived mAbs with excellent specificity for different POx species and notable selectivity for highly branched polymer architectures over linear systems.

The pathophysiological relationship between wound healing impairment and diabetes is an intricate process. Burn injury among diabetes patients leads to neurological, vascular, and immunological abnormalities along with impaired activities of cell proliferation, collagen production, growth factors, and cytokine activities with huge bacterial infestation. In our study, we aimed to achieve a burn wound dressing material with the help of electrospun Chitosan/Polyethylene oxide/Rosmarinic acid (CS/PEO/RA) nanofibers.

One of the main factors that have made it difficult to control malaria is the large number of parasites that are resistant to the usual antimalarial drugs. Therefore, the development of new drugs that are more effective and with low toxicity for humans is necessary. In this work, we evaluated the adduct 2-(3-hydroxy-1-methyl-2-oxoindolin-3-yl) acrylonitrile, also called CHISACN, as a potential antimalarial through in vitro studies, and evaluated its effects in silico and in vivo toxicology.

Heavily exuding wounds are difficult to heal due to the accumulation of a large amount of exudates and the difficulty in efficient delivery of drugs by conventional wound dressings. Herein, inspired by the microstructure and function of octopus sucker (OS) and tree trunk (TT), we propose a bioinspired strategy to fabricate novel bioinspired OS&TT bilayered wound dressing, assembled by a lower OS-like nanofiber membrane with concave convex arrays and an upper TT-like nanofiber sponge with vertically aligned pores. The integration of bioinspired concave arrays and vertically aligned pores endows the bioinspired OS&TT dressing with dual vertical suction property, enabling effective drainage of significant amount of accumulated liquid.

Actinomycetes are an important source of secondary metabolites such as antibiotics and other active natural products. Many well-known antibiotics, such as streptomycin, oxytetracycline, and tetracycline, are produced by actinomycetes. Different types of antibiotics have distinct mechanisms of action against microorganisms: inhibit protein synthesis, inhibit nucleic acid synthesis, or inhibit cell wall synthesis.
