Multi‐Omics Analysis of Human Blood Cells Reveals Unique Features of Age‐Associated Type 2 CD8 Memory T Cells

Aging Cell, Volume 25, Issue 2, February 2026.
Aging drives the accumulation of CXCR3‐ central memory CD8 T cells that exhibit Th2‐like transcriptional and epigenetic programs. These cells display a pathogenic Th2‐skewed profile and are associated with age‐related diseases, including asthma, chronic liver disease, and type 2 diabetes.

Pressure Response of Crystalline Fluoranthene Probed by Raman Spectroscopy

Crystals
The pressure response and structural stability of fluoranthene crystals up to 8 GPa are investigated using Raman spectroscopy. The vast majority of the Raman peaks upshift with pressure, either sublinearly (intermolecular modes) or quasilinearly ...

Atmospheric chemistry of gas-phase polycyclic aromatic hydrocarbons: formation of atmospheric mutagens. [PDF]

, 1994
The atmospheric chemistry of the 2- to 4-ring polycyclic aromatic hydrocarbons (PAH), which exist mainly in the gas phase in the atmosphere, is discussed. The dominant loss process for the gas-phase PAH is by reaction with the hydroxyl radical, resulting

Evaluation of the pollution pressures posed by groups of chemicals on British riverine invertebrate populations

Biological Reviews, Volume 101, Issue 1, Page 106-127, February 2026.
ABSTRACT Globally, rivers receive a diverse range of chemicals, including metals, pesticides, persistent organic pollutants, petrochemicals, human and veterinary pharmaceuticals and personal care products. However, the extent to which these different chemical groups affect riverine invertebrate communities is not well defined.

Olive leaf extract and butylated hydroxytoluene as antioxidants in refined versus whole wheat flour crackers: a physico‐chemical characterization

Journal of the Science of Food and Agriculture, Volume 106, Issue 2, Page 1339-1350, 30 January 2026.
Abstract BACKGROUND This study investigated the physico‐chemical properties of four cracker samples formulated with refined (RF) or whole wheat flour (WF), and enriched with olive leaf extract in either free form (OLE) or encapsulated form (MCR), as well as with butylated hydroxytoluene (BHT) antioxidant, in comparison with non‐enriched control samples

Reconstructing historical trends of polycyclic aromatic hydrocarbon deposition in a remote area of Spain using herbarium moss material [PDF]

, 2010
Herbarium mosses from 1879-1881, 1973-1975 and 2006-2007 were used to investigate the historical changes of atmospheric deposition of polycyclic aromatic hydrocarbons (PAHs) at a remote site located in Northern Spain.

Fluoranthene degradation in a persulfate system activated by sulfidated nano zero-valent iron (S-nZVI): performance and mechanisms

Water Science and Technology
Fluoranthene (FLT) has received mounting focus due to its hazardous properties and frequent occurrence in groundwater. In this study, sulfidated nano zero-valent iron (S-nZVI) was selected as an efficient catalyst for activating persulfate (PS) to ...
