Acinetobacter baumannii stands out for its antimicrobial resistance and high capacity to cause hospital infections, posing a severe threat to global public health. Thus, there is an urgent need for new therapeutic strategies. This work applied photodynamic therapy (PDT) with curcumin to Acinetobacter baumannii, and bacterial cell viability was assessed.

NO is a significant primary atmospheric pollutant that plays a key role in atmospheric chemistry. It serves as a crucial precursor to photochemical smog, acid rain, and secondary particulate matter and is instrumental in determining the atmospheric oxidation capacity. In this review, we focus on the heterogeneous chemistry of NO, which has been demonstrated to significantly influence the sources and sinks of various nitrogen-containing species through field measurements and model simulations.

Dentin hypersensitivity is primarily caused by the exposure of dentinal tubules due to various factors, so the key to treatment is to effectively seal these exposed tubules. However, traditional dentinal tubule sealants used in clinical practice often fail to adhere securely to the tubule surface when exposed to external stimuli, resulting in a recurrence of sensitivity. In this study, we developed a silicon micromotor that moved autonomously and loaded with silver nanoparticles and a photosensitive adhesive for dentin sensitivity therapy.

Abiotic stresses, notably cold stress, significantly influence various aspects of plant development and reproduction. Various approaches have been proposed to counteract the adverse impacts of cold stress on plant productivity. The unique properties of nanoparticles contribute to an enhanced tolerance of plants to challenging conditions.

We report the case of an 18-month-old boy who developed a phototoxic skin reaction to terbinafine on his scalp, ears, and face in the form of disseminated erythematous plaques, which resembled subacute lupus erythematosus (SCLE) in their clinical presentation. Skin changes appeared a short time after the boy was exposed to sunlight during the period of time when he was treated with oral terbinafine due to Microsporum canis fungal scalp infection. Tinea capitis is a common dermatophyte infection primarily affecting prepubertal children (1).
