Hyperlipidemia is intricately associated with the dysregulation of gut microbiota and host metabolomes. This study explored antihyperlipidemic function oryzanol investigated whether affected microbiome its related metabolites. Hamsters were fed a standard diet (Control) high fat cholesterol (HFCD) or without oryzanol, separately. Our results showed that significantly decreased HFCD-induced accumulation, serum total cholesterol, low-density lipoprotein (LDL-c), LDL-c/HDL-c ratio,...

δ-Tocotrienol, an important component of vitamin E, has been reported to possess some physiological functions, such as anticancer and anti-inflammation, however their molecular mechanisms are not clear. In this study, δ-tocotrienol was isolated purified from rice bran. The anti-inflammatory effect mechanism against lipopolysaccharides (LPS) activated pro-inflammatory mediator expressions in RAW264.7 cells were investigated. Results showed that significantly inhibited LPS-stimulated nitric...

The increasing demand for bio-based chemicals and sustainable materials has placed biomass-derived lactic acid in the spotlight as a key building block biodegradable polylactic (PLA). Perennial ryegrass (Lolium perenne) is promising feedstock due to its high dry matter (DM) yield, adaptability, widespread agricultural use. This study investigates an integrated acid–silage cascade process, focusing on how pH regulation, harvest timing, biomass characteristics influence production...

Perennial ryegrass (Lolium perenne) is an underutilized lignocellulosic biomass that has several benefits such as high availability, renewability, and yield. The grass press-juice obtained from the mechanical pretreatment can be used for bio-based production of chemicals. Lactic acid a platform chemical attracted consideration due to broad area applications. For this reason, more sustainable lactic expected increase. In work, was produced using complex medium at bench- reactor scale, results...
