Influence of swine manure on growth, P uptake and activities of acid phosphatase and phytase of Polygonum hydropiper.

Only registered users can translate articles

Excessive application of animal manure to the farmland results in enrichment of P in the soil. Phytoremediation is a promising strategy for extracting excess P from manure impacted soil. P uptake characteristics of a mining ecotype (ME) and a non-mining ecotype (NME) of Polygonum hydropiper were

Emodin inhibits tonic tension through suppressing PKCδ-mediated inhibition of myosin phosphatase in rat isolated thoracic aorta.

Only registered users can translate articles

OBJECTIVE Dysregulated tonic tension and calcium sensitization in blood vessels has frequently been observed in many cardiovascular diseases. Despite a huge therapeutic potential, little is known about natural products targeting tonic tension and calcium sensitization. METHODS We screened natural

Stilbenes with Potent Protein Tyrosine Phosphatase-1B Inhibitory Activity from the Roots of Polygonum multiflorum.

Only registered users can translate articles

Seven new stilbene glycosides including three dimers (1-3) and four monomers (4-7) were isolated from the roots of Polygonum multiflorum along with nine previously identified stilbenes (8-16). In addition, two deglucosylated stilbenes, 2a and

Anthraquinones, Cdc25B phosphatase inhibitors, isolated from the roots of Polygonum multiflorum Thunb.

Only registered users can translate articles

Three anthraquinones, Cdc25B phosphatase inhibitors, were isolated from the methanolic extract of the roots of Polygonum multiflorum Thunb. (Polygonaceae). Anthraquinones, physcion (1), emodin (2), and questin (3), inhibited the enzymatic activity of Cdc25B phosphatase with IC(50) values of 62.5,

Heshouwu (Polygonum multiflorum Thunb.) Extract Attenuates Bone Loss in Diabetic Mice.

Only registered users can translate articles

This study investigated the effects and mechanism of Heshouwu (Polygonum multiflorum Thunb.) water extract (HSW) on diabetes-related bone loss in mice. HSW was orally administered (300 mg/kg body weight) to high-fat diet and streptozotocin-induced diabetic mice for 10 weeks. HSW significantly

Effects of Hot Water Extracts from Polygonum multiflorum on Ovariectomy Induced Osteopenia in Mice.

Only registered users can translate articles

Polygonum multiflorum (PM), a traditional Chinese medicine, is used to treat various diseases including nonalcoholic fatty liver disease and hyperlipidemia. However, the influence of PM on osteoporosis in animals is unclear. The present study investigated the antiosteoporotic effect of PM on bone

Anti-proliferative effect of an extract of the root of Polygonum multiflorum Thunb. on MCF-7 human breast cancer cells and the possible mechanisms.

Only registered users can translate articles

The root of Polygonum multiflorum Thunb. (PM) is utilized to treat many diseases associated with aging. Research also indicates that PM inhibits the proliferation of certain types of cancer cells. The aim of the present study was to evaluate the inhibitory effect of PM extract (PME) on the

Root physiological adaptations involved in enhancing P assimilation in mining and non-mining ecotypes of Polygonum hydropiper grown under organic P media.

Only registered users can translate articles

It is important to seek out plant species, high in phosphorus (P) uptake, for phytoremediation of P-enriched environments with a large amount of organic P (Po). P assimilation characteristics and the related mechanisms of Polygonum hydropiper were investigated in hydroponic media containing various

The protective effect of juglanin on fructose-induced hepatitis by inhibiting inflammation and apoptosis through TLR4 and JAK2/STAT3 signaling pathways in fructose-fed rats.

Only registered users can translate articles

High fructose-feeding is an essential causative factor leading to the development and progression of hepatitis associated with high levels of endotoxin (LPS). Juglanin, as a natural compound extracted from the crude Polygonum aviculare, displayed inhibitory activity against inflammation response and

Effects of Processed Polygonum multiflorum with KIOM Patent on Bone Remodeling-Related Protein Expression in Human Osteoblast-Like SaOS-2 Cells.

Only registered users can translate articles

This present study evaluated the effects of processed P. multiflorum on osteogenesis using Sarcoma osteogenic (SaOS-2) cell lines and osteoclastogenesis of bone marrow-derived macrophage cells (BMM) and to elucidate differences in effect on the expression of bone-related proteins between

Tetrahydroxy stilbene glucoside protected against diabetes-induced osteoporosis in mice with streptozotocin-induced hyperglycemia.

Only registered users can translate articles

Tetrahydroxy stilbene glucoside (TSG), an active component from medicinal herb Polygonum multiflorum Thunb, could block the activity of the tissue renin-angiotensin system (RAS), which plays a critical role in development of diabetic osteoporosis. This study aimed to determine if TSG therapy could

Multiflorumisides HK, stilbene glucosides isolated from Polygonum multiflorum and their in vitro PTP1B inhibitory activities

Only registered users can translate articles

A phytochemical study on a 70% EtOH extract of dried roots of Polygonum multiflorum resulted in the isolation of four undescribed stilbene glucosides, namely multiflorumisides HK (1-4). The structures of the natural products were elucidated by 1D and 2D nuclear magnetic resonance (NMR) as well as

Neuroprotective effects of Polygonum multiflorum extract against glutamate-induced oxidative toxicity in HT22 hippocampal cells.

Only registered users can translate articles

BACKGROUND Dried roots of Polygonum multiflorum have traditionally been used in the retarding of aging process in East Asian countries and its extracts exhibit anti-oxidative activities. METHODS Neuroprotective effects of ethyl acetate extract from Polygonum multiflorum (EEPM) were investigated

Tetrahydroxystilbene glucoside isolated from Polygonum multiflorum Thunb. demonstrates osteoblast differentiation promoting activity.

Only registered users can translate articles

Polygonum multiflorum Thunb. is a traditional Chinese medicinal herb that has been widely used to treat age-associated diseases. Tetrahydroxystilbene glucoside (TSG), also known as 2,3,5,4-tetrahydroxystilbene-2-O-β-D-glucoside, is a major component of this herb. The present study was designed to

Protective effect of tetrahydroxystilbene glucoside against hydrogen peroxide-induced dysfunction and oxidative stress in osteoblastic MC3T3-E1 cells.

Only registered users can translate articles

Oxidative stress can induce apoptosis and decrease activities of osteoblasts. 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside (TSG), is a potent antioxidant derived from a Chinese herb Polygonum multiflorum Thunb. To evaluate the protective effect provided by TSG to osteoblastic MC3T3-E1 cells, the
