During the last decade, our understanding of the molecular mechanisms regulating the cellular environment has made significant advances. With the new dynamical description of the functionalities of the cell, several processes known to play a crucial role in the onset of aging such as cell senescence, the increase of ROS level and telomere shortening appear to be a consequence of the disruption of a systemic dynamical equilibrium established within the cellular environment. In this short review, I discuss how these new features provide us with a way to improve the current evolutionary theory of aging and help to clarify the role played by aging within the context of the evolution.

Background: HCC develops in the context of chronic inflammation; however, the opposing roles the immune system plays in both the development and control of tumors are not fully understood. Mapping immune cell interactions across the distinct tissue regions could provide greater insight into the role individual immune populations have within tumors.
Methods: A 39-parameter imaging mass cytometry panel was optimized with markers targeting immune cells, stromal cells, endothelial cells, hepatocytes, and tumor cells.

Emerging mercury-free ultraviolet (UV) sources, such as krypton chloride excimer (KrCl*) lamps and UV light emitting diodes (UV-LEDs), emit diverse wavelengths with distinct inactivation mechanisms. The combined application has the potential to improve disinfection effectiveness through synergism. In this study, a mini-fluidic photoreaction system equipped with a KrCl* lamp (222 nm) and a strip of UV-LEDs (275 nm) was developed, which could individually/simultaneously deliver accurate UV radiation(s) at 222 nm (0.

Radiation therapy (RT) is fundamental to the fight against cancer because of its exceptional ability to target and destroy cancer cells. However, conventional radiation therapy can significantly affect the adjacent normal tissues, leading to fibrosis, inflammation, and decreased organ function. This tissue damage not only reduces the quality of life but also prevents the total elimination of cancer.

However, it is necessary to develop (non-)enzymatic nanotechnologies capable of selectively killing tumour cells without harming normal cells. Their therapeutic characteristics should be the adaption of tumours' extra- and intracellular environment to being specifically active.

Perpendicular nanochannel creation of two-dimensional (2D) nanostructures requires highly controlled anisotropic drilling processes of the entire structure via void formation. However, chemical approaches for the creation of porosity and defects of 2D nanostructures have been challenging due to the strong basal plane chemical stability and the use of harsh reactants, tending to give randomly corroded 2D structures. In this study, we introduce Lewis acid-base conjugates (LABCs) as molecular drillers with attenuated chemical reactivity which results in the well-defined perpendicular nanochannel formation of 2D TiS nanoplates.
