The challenges associated with prolonged healing or non-healing of chronic diabetic wounds contribute significantly to the increased incidence of lower limb amputation. A pivotal factor in the impediment of healing is the reduced production of endogenous nitric oxide (NO) due to the hyperglycemic microenvironment typical of chronic diabetes. While both endogenous and exogenous NO have been shown to promote the healing process of diabetic wounds, the direct application of NO in wound management is limited due to its gaseous nature and the risk of explosive release.

In modern agriculture, control of insect pests is achieved by using insecticides that can also have lethal and sublethal effects on beneficial non-target organisms. Here, we investigate acute toxicity and sublethal effects of four insecticides on the males' sex pheromone response and the female host finding ability of the Drosophila parasitoid Leptopilina heterotoma. The nicotinic acetylcholine receptor antagonists acetamiprid, flupyradifurone and sulfoxaflor, as well as the acetylcholinesterase inhibitor dimethoate were applied topically as acetone solutions.

Silver sulfadiazine (SSD) is a widely used antibacterial agent for burn wound treatment owing to its capability in re-epithelialization and wound healing. However, due to its low solubility, the need for an effective drug delivery system is mandatory. This study aimed to optimize SSD nanostructured lipid-based carriers (NLCs), incorporated in a collagen sponge form as an innovative topical dosage form for effective burn wound treatment.

Disulfiram (DSF), which has been traditionally used to treat alcoholism, has been shown to inhibit tumor growth, indicating its potential as an anticancer agent. However, its development and application are hindered by its poor water solubility, instability in physiological environments, and low bioavailability. In this study, phenylboronic acid-chitosan (PBA-CS) grafts were synthesized using the carbodiimide method.
