Comprehensive review of polycyclic aromatic hydrocarbons in water sources, their effects and treatments.

Science of the Total Environment, 2019
Polycyclic aromatic hydrocarbons (PAHs) are principally derived from the incomplete combustion of fossil fuels. This study investigated the occurrence of PAHs in aquatic environments around the world, their effects on the environment and humans, and ...

Methane to Liquid Hydrocarbons over Tungsten-ZSM-5 and Tungsten Loaded Cu/ZSM-5 Catalysts [PDF]

, 2006
Metal containiiig ZSM-5 can produce higher hydrocarbons in metallane oxidation. Many researchers have studied the applicability of HZSM-5 and modify ZSM-5 for ruethane coriversion to liquid hydrocarbons, but their research results still lead to low ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.
