It has been shown that interferon-gamma (IFN-gamma) plays a role in the regulation of interleukin-8 (IL-8), nitric oxide (NO), and tumor necrosis factor-alpha (TNF-alpha) secretion by macrophages stimulated with lignin derivatives, such as EP3, and lipopolysaccharides (LPS) [Cytokine 11 (1999) 571].

In order to investigate the action point of lignin-carbohydrate complex (Fr4) from Lentinus edodes mycelia extract, DNA microarray analysis was performed, using mouse macrophage-like J774.1 cells. Among seven lignin-carbohydrate complex fractions, Fr4 showed the highest stimulatory activity of tumor

BACKGROUND
Recently, a prominent antiviral and macrophage stimulatory activity of cacao lignin-carbohydrate complex (LCC) has been reported. However, the solubility and sterility of LCC have not been considered yet. In the present study, complete solubilisation and sterilisation was achieved by

Kraft lignin is a polyphenolic compound generated as a by-product from the kraft pulping process in large quantities annually worldwide. In addition to its commercial availability, its structural features make it worth to be considered in the pharmaceutical area. The present study was carried out to

BACKGROUND
BcGs1, a cell wall-degrading enzyme (CWDE), was originally derived from Botrytis cinerea. Our previous study revealed that BcGs1 could trigger defense responses and protect plants against various pathogens. We researched the defense response mechanism underlying this BcGs1 elicitation in
Experimental evidence for heat plume-induced cavitation and xylem deformation as a mechanism of rapid post-fire tree mortality.

Recent work suggests that hydraulic mechanisms, rather than cambium necrosis, may account for rapid post-fire tree mortality. We experimentally tested for xylem cavitation, as a result of exposure to high-vapour-deficit (D) heat plumes, and permanent xylem deformation, as a result of thermal
