The antibacterial agent chlorhexidine has long been used as an agent for medical antisepsis. This compound is a membrane active agent which probably has its major antibacterial action by interference with the function of cellular membranes. The results demonstrated an inhibition of oxygen utilisation by bacteria which was related to falls in cellular ATP levels. There was an effect on the outer membranes of Gram-negative bacteria which allowed the release of periplasmic enzymes. The inner membrane was not ruptured but its functionality was breached and there was an inhibition of active uptake of small molecules which did not appear to be related to cellular ATP levels.

Indole, a ubiquitous structural motif in bioactive compounds, has played a pivotal role in drug discovery. Among indole derivatives, indole-3-carboxaldehyde (I3A) has emerged as a particularly promising scaffold for the development of therapeutic agents. This review delves into the recent advancements in the chemical modification of I3A and its derivatives, highlighting their potential applications in various therapeutic areas.

Photothermal therapy (PTT) demonstrates significant potential in cancer treatment, wound healing, and antibacterial therapy, with its efficacy largely depending on the performance of photothermal agents (PTAs). Metal-phenolic network (MPN) materials are ideal PTA candidates due to their low cost, good biocompatibility and excellent ligand-to-metal charge transfer properties. However, not all MPNs exhibit significant photothermal properties, and the vast chemical space of MPNs (over 700,000 potential combinations) complicates the screening of high-photothermal materials.

A 9-year-old neutered male cairn terrier dog was initially presented because of inappetence, increased respiratory effort, and occasional coughing. A cavitary lung mass was diagnosed using CT and removed with lung lobectomy. Histopathology of the mass revealed necrosuppurative inflammation with acid-fast rod bacteria in macrophages, with spp.

Antibiotic resistance is one of the most urgent threats to public health. The development of antibiotic resistance can be reduced by the use of narrow-spectrum antibiotics that target specific bacteria, meaning that fewer non-harmful bacteria are killed and other harmful bacteria are not exposed to selection pressure. However, many narrow-spectrum antibiotics were introduced decades ago and therefore lack regulatory documentation in line with current standards.

We report a case of a woman presenting with an erythematous finger nodule, with a history of exposure to tropical fish. The erythematous nodules subsequently spread proximally from the finger. Initial treatment with oral amoxicillin-clavulanate was unsuccessful, and she developed a drug eruption.
