DNA damage is a driver of cancer formation, leading to the impairment of repair mechanisms in cancer cells and rendering them susceptible to DNA-damaging therapeutic approaches. The concept of "synthetic lethality" in cancer clinics has emerged, particularly with the use of PARP inhibitors and the identification of DNA damage response (DDR) mutation biomarkers, emphasizing the significance of targeting DDR in cancer therapy. Novel approaches aimed at genome maintenance machinery are under development to further enhance the efficacy of cancer treatments.

Cardiologists have analyzed daily patterns in the incidence of sudden cardiac death to identify environmental, behavioral, and physiological factors that trigger fatal arrhythmias. Recent studies have indicated an overall increase in sudden cardiac arrest during daytime hours when the frequency of arrhythmogenic triggers is highest. The risk of fatal arrhythmias arises from the interaction between these triggers-such as elevated sympathetic signaling, catecholamine levels, heart rate, afterload, and platelet aggregation-and the heart's susceptibility (myocardial substrate) to them.

Electronic address:
The development of natural rubber (NR) gloves with superior antibacterial and enhanced mechanical properties is critical for safeguarding healthcare personnel. In this study, Ti-based MXene (TiCT) nanosheets were employed for the first time as an antibacterial agent to improve the antimicrobial performance of NR. Through SiO₂ intercalation via electronic assembly, the antibacterial efficacy of MXene was significantly boosted, achieving 100 % lethality against E.
