Discovery of alternative sources of antimicrobial agents are essential in the ongoing battle against microbial pathogens. Legislative and scientific challenges considerably hinder the discovery and use of new antimicrobial drugs, and new approaches are in urgent demand. On the other hand, rapid, specific and sensitive detection of airborne pathogens is becoming increasingly critical for public health. In this respect affinity oligonucleotides, aptamers, provide unique opportunities for the development of nanotechnological solutions for such medical applications. In recent years, aptamers specifically recognizing microbial cells and viruses showed great potential in a range of analytical and therapeutic applications. This article describes the significant advances in the development of aptamers targeting specific pathogens. Therapeutic application of aptamers as neutralizing agents demonstrates great potential as a future source of antimicrobial agent.

Unusual Iron-Independent Ferroptosis-like Cell Death Induced by Photoactivation of a Typical Iridium Complex for Hypoxia Photodynamic Therapy.
ACS Appl Mater Interfaces

Ferroptosis is a unique cell death mode that relies on iron and lipid peroxidation (LPO) and is extensively utilized to treat drug-resistant tumor. However, like the other antitumor model, requirement of oxygen limited its application in treating the malignant tumors in anaerobic environments, just as photodynamic therapy, a very promising anticancer therapy. Here, we show that an iridium(III) complex (Ir-dF), which was often used in proton-coupled electron transport (PCET) process, can induce efficient cell death upon photo irradiation, which can be effectively protected by the typical ferroptosis inhibitor Fer-1 but not by the classic iron chelating agents and ROS scavengers.

To significantly reduce CRC incidence and mortality, a more convenient screening measure for advanced precancerous lesions (APL) and CRC is urgently needed.

Methods: From April 2023 through July 2023, 110 BPH patients and 120 healthy individuals who underwent examinations at our hospital were selected as study subjects. The concentrations of C-reactive protein (CRP), procalcitonin (PCT), serum amyloid A (SAA), complement 3 (C3), and complement 4 (C4) were measured in both groups.
The Role and Implications of Epidermal Dysfunction in the Pathogenesis of Inflammaging.
J Invest Dermatol
January 2025
Dermatology Hospital of Southern Medical University, Guangzhou, China. Electronic address:
Inflammaging has long been linked to the pathogenesis of various aging-associated disorders, including cardiovascular disease, obesity, type 2 diabetes, and dementia. Yet, the origins of inflammaging remain unclear. Although inflammatory dermatoses such as psoriasis and atopic dermatitis predispose to the development of certain aging-associated disorders, suggesting a pathogenic role of cutaneous inflammation in these disorders, the great majority of aged humans do not have inflammatory dermatoses.

Nanoplastics, as emerging contaminants, have been causing great panic, potentially affecting human health in recent years. Some studies have indicated that nanoplastics may induce severe toxicity. However, the mechanisms underlying this potential toxicity are insufficiently understood.
