Cadmium bioaccumulation factors for terrestrial species: Application of the mechanistic bioaccumulation model OMEGA to explain field data

Science of The Total Environment, 2008
In environmental risk assessment of metals it is often assumed that the biota-to-soil accumulation factor (BSAF) is generic and constant. However, previous studies have shown that cadmium bioaccumulation factors of earthworms and small mammals are inversely related to total soil concentrations.

Oral Astilbin Nanogels Modulate Senescence‐Associated CD4+ T Cells and Promote Treg Induction in Aged Mice with Colitis

Advanced Science, EarlyView.
Fluorinated β‐glucan/pectin nanogels enable colon‐targeted oral delivery of astilbin through gastrointestinal protection, β‐glucanase‐responsive release, mucus penetration, and prolonged retention. The released astilbin attenuates senescence‐associated features of CD4+ T cells and promotes Treg responses, while the nanogel matrix modulates the gut ...

Precision Nanomedicine for Traumatic Neural Injury: Functional Paradigms and Translational Frameworks

Advanced Science, EarlyView.
This review presents a pathology‐driven framework unifying nanomedicine across TBI, SCI, and PNI. Epidemiological evidence and comparative single‐cell transcriptomic reanalysis define shared pathological modules, injury‐specific effectors, and therapeutic bottlenecks. Six functional paradigms connect nanomaterial structure and biological fate to injury‐

Bioaccumulation and translocation factors of petroleum hydrocarbons in Aeluropus littoralis [PDF]

Environmental Health Engineering and Management, 2017
Background Polycyclic aromatic hydrocarbons (PAHs), which consist of fused conjugated aromatic rings, not only are toxic to humans and other living organisms, but will also pollute groundwater. These compounds can be point source or non-point source and are one of the most widespread organic pollutants.

Weak‑Solvation‑Mediated Localized High‑Concentration Electrolyte for Sodium Metal Batteries

Advanced Science, EarlyView.
A weak‑solvation strategy using MTBE as a fluorine‑free diluent constructs a localized high‑concentration structure, promoting FSI− coordination and forming an inorganic‑rich SEI. This enables stable cycling with high‑loading cathodes and pouch cells, offering a sustainable, PFAS‑free electrolyte for sodium metal batteries.

Valorization of bark extracts from Cerrado and Amazon species: phenolic characterization, antioxidant capacity, and photoprotective potential for circular bioeconomy applications

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Tree bark remains an underexploited source of high‐value‐added phenolic compounds with potential circular bioeconomy applications. This work characterized bark extracts from two species of distinct Brazilian biomes, Stryphnodendron adstringens (Cerrado) and Myrcia eximia (Amazon), obtained with three solvents (ethanol, methanol and acetone ...

Environmental impact of antidepressants: Is a new prescription framework possible?

British Journal of Clinical Pharmacology, EarlyView.
Aims Antidepressants such as venlafaxine and sertraline pose high risks to water ecosystems. As depressive disorders and other mental health conditions become increasingly prevalent worldwide, prescription and environmental presence of these pharmaceuticals continue to rise. This study explores the practical viability of a new framework for prescribing
