Emerging and legacy hydrophobic pollutants, including halogenated flame retardants (HFRs), organophosphorus FRs (OPFRs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs), as well as polycyclic aromatic hydrocarbons (PAHs) were determined in coastal sediments of Hainan Island, southern China, where little information is known about their contamination. The HFRs were dominated by decabrominated diphenyl ethers (median = 1.32 ng/g) and novel decabromodiphenyl ethane (1.87 ng/g). HFR and PAH concentrations had similar spatial distributions, with higher levels in the river and near the estuary...

Mesenchymal stem cells (MSCs) have potential uses for cartilage repair due to the potential of chondrogenic differentiation. However, developing effective approaches to regulate chondrogenesis in vivo remains a big challenging. To address the limitations, we propose the application of magnetic fields, which features excellent performance for tissue penetration, good biocompatibility even at high magnetic strength, and wireless remote control. To test this concept, a pulsed magnetic field (PMF) was used to enhance the chondrogenesis of SPIO-labeled MSCs in a rat model of cartilage defects...

As people age, iron deposits in different areas of the brain may impair normal cognitive function and behavior. Abnormal iron metabolism generates hydroxyl radicals through the Fenton reaction, triggers oxidative stress reactions, damages cell lipids, protein and DNA structure and function, and ultimately leads to cell death. There is an imbalance in iron homeostasis in Alzheimer's disease (AD). Excessive iron contributes to the deposition of β-amyloid and the formation of neurofibrillary tangles, which in turn, promotes the development of AD...
