The problem is that the tree produces a substance called juglone, which is toxic to many other kinds of plants, big and small.
In previous studies, we showed that TBARS increased in calf-thymus DNA treated with Q7 or juglone [39].
These unique compounds include the quinone juglone, the tannin tellimagrandin, and the flavonol morin (4)--all strong cancer inhibitors.
Some specific topics treated include green technology, "smart city" construction, architectural parametric design, an aquatic logistics model based on supply chain management, improvement of a headphone speaker production line, the effects of juglone on the migration of human ovarian cancer cells, and the design and implementation of an oilfield heterogeneous data-integration model based on ontology.
elegans in vivo against oxidative stress induced by the pro-oxidant juglone (a naphthoquinone from Juglans regia).
Terzi, 2008, [17] had also observed such kind of high negative inhibition where juglone on allelochemicals from walnut leaf juice significantly retarded the seedling growth of musk melon and cucumber.
Juglone treatment resulted in the accumulation of pThr53 suggesting a role for Pin1 in regulating rDAT T53 phosphorylation and thereby its function.
The black walnut (Juglans nigra) produces the allelochemical juglone, which affects some species greatly while others not at all.
Allelopathic effects of juglone on germination and growth of several herbaceous and woody species.
Recent studies have shown that treatment of cells with pin1 inhibitor juglone delays the growth of various tumour cell lines (187), suggesting that inhibition of pin1 can be used as an approach for inhibiting tumour growth.
Juglone was extracted from Juglans mandshurica bark via vacuum-assisted steam stripping.
