The immune-enhancing potential of peptide fractions from fermented Spirulina platensis by mixed probiotics
- First Published: 27 May 2020

The mixed fermentation by probiotics enhanced the immunomodulatory activity of S. platensis with higher lymphocyte proliferation compared with non-fermented S. platensis. Notably, the low molecular weight (<3 kDa) peptide fraction from fermented S. platensis (L-PFS), especially at 40 μg/ml, presented the strongest activity in promoting lymphocytes proliferation and modulating cytokines (IL-2 and IL-10) secretion and the relative mRNA expression of Th1 cytokines (IFN-γ, IL-2 and TNF-α) and Th2 cytokines (IL-4 and IL-10), thus promoted the Th1/Th2 balance.

- First Published: 16 April 2020

- Different oligosaccharides were prepared by gel-filtration and HPLC chromatography from the hydrolysate of Tremella polysaccharide.
- The structures of the oligosaccharide were identified as (1→3) oligomannans by component sugars, methylation and LC-MS analysis.
- The cell experiment showed the (1→3) hexmannan is the smallest active structure for keeping the cytokine-stimulating activity. The result shall be profitable in further utilization and research for Tremella polysaccharide.
Esculetin and idebenone ameliorate galactose-induced cataract in a rat model
- First Published: 16 April 2020

The present study confirms the link between high galactose levels and apoptosis of lens epithelial cells. Esculetin has been found to prevent the accumulation of polyol and AGEs in the lens tissue. Esculetin and idebenone have been found to protect the lens against galactose-induced oxidative stress, DNA damage, and lipid peroxidation. Overall, esculetin and idebenone are potentially useful for delaying galactose-induced cataractogensis through the suppression of apoptotic cell death in the lens epithelium.

Anti-inflammatory effects of Beopje curly dock (Rumex crispus L.) in LPS-induced RAW 264.7 cells and its active compounds
- First Published: 26 May 2020

Inflammation is a defense response of the body to stimuli. Curly dock (CD) is an herbal food with anti-inflammatory effects. Beopje is a herbal food processing method that reduces toxicity and enhances beneficial effects. This study investigated the effects of CD and Beopje curly dock (CD-B) extracts on lipopolysaccharide (LPS)-induced inflammatory damage in RAW 264.7 cells. Our results indicate that CD-B has a more significant inhibitory effect on the LPS-induced inflammatory response in RAW264.7 cells than CD, suggesting that the Beopje process potentially enhances the anti-inflammatory effect of CD.
