Abstract
Acanthopanax senticosus (Ciwujia) has broad-spectrum pharmacological activities, including osteoprotective effects. However, the mechanisms underlying these effects remain unclear. We investigated whether Acanthopanax senticosus aqueous extract (ASAE) ameliorates ovariectomy-induced bone loss in middle-aged mice through inhibition of osteoclastogenesis. In vitro, ASAE significantly suppressed the receptor activator of nuclear factor-κB ligand (RANKL)-stimulated osteoclast differentiation and formation of F-actin rings by downregulating the expression of the nuclear factor of activated T cells, cytoplasmic 1 (NFATc1), c-Fos, and osteoclastogenesis-related marker genes and proteins, including c-Src, tartrate-resistant acid phosphatase (TRAP), cathepsin K, β3-integrin, and matrix metallopeptidase-9 (MMP-9). This was achieved by inhibiting RANK signaling pathways, including p65, c-Jun N-terminal kinase, extracellular signal-regulated kinase, and p38 in osteoclast precursors. In vivo, ASAE markedly ameliorated bone loss in ovariectomized (OVX) middle-aged mice. ASAE significantly inhibited the serum levels of tartrate-resistant acid phosphatase 5b (TRACP-5b) and RANKL, whereas it increased those of osteocalcin, procollagen 1 N-terminal peptide (P1NP), and osteoprotegerin in OVX mice. ASAE significantly inhibited the OVX-induced expression of osteoclast-specific proteins and genes in the femur. In conclusion, ASAE prevents ovariectomy-induced bone loss in middle-aged mice by inhibiting RANKL-induced osteoclastogenesis through suppression of RANK signaling pathways and could be potentially used in mediated treatment of osteoclast-related diseases (e.g., osteoporosis).

Abstract
The great challenge in preparing a biomimetic enzyme sensor is to have sensitivity and selectivity equal to or better than its corresponding biological sensor. Porous electrodes possess a large surface area and are often used to greatly improve the sensor sensitivity. However, how to tailor the pore structure, especially the pore size distribution to further improve the sensitivity and selectivity of a biomimetic sensor, has not been investigated yet. The superoxide anion (O2˙-) plays essential roles in various biological processes and is of importance in clinical diagnosis and life science research. It is generally detected by the superoxide dismutase enzyme. Herein, we delicately tailor the pore structure of carbon nanofibers (CNFs) by pyrolysis to obtain an optimal mesopore structure for strong adsorption of DNA, followed by guiding the growth of Mn3(PO4)2 as a biomimetic enzyme toward highly sensitive detection of O2˙-. The Mn3(PO4)2-DNA/CNF sensor achieves the best sensitivity among the reported O2˙- sensors while possessing good selectivity. The enhancement mechanism is also investigated, indicating that the mesopore ratio of CNFs plays an essential role in the high sensitivity and selectivity due to their strong adsorption of DNA for guiding the growth of a large amount of uniform sensing components, Mn3(PO4)2, toward high sensitivity and selectivity. The biomimetic sensor was further used to in situ monitor O2˙- released from human keratinocyte cells and human malignant melanoma cells under drug stimulation, showing high sensitivity to real-time quantitative detection of O2˙-. This work provides a highly sensitive in situ real-time biomimetic O2˙- sensor for applications in biological research and diagnosis, while shedding light on the enhancement mechanism of the pore structure, especially the pore size distribution of a porous electrode for high performance sensing processes.

Abstract
The roots of Eleutherococcus senticosus (Rupr. & Maxim.) Maxim., a well-known medicinal plant from Eastern Asia, are used worldwide for their known beneficial medicinal properties. Recently, the leaves have been used as an alternative to the roots. The present study was aimed at exploring the leaf essential oil as a potential source of compounds for mosquito management. Gas chromatography/mass spectrometry analysis of the leaf essential oil revealed 87 compounds, constituting 95.2% of the oil. α-Bisabolol (26.46%), β-caryophyllene (7.45%), germacrene D (6.87%), β-bisabolene (4.95%), and α-humulene (3.50%) were five of the major constituents. The essential oil was subjected to biting deterrence and repellent activity against mosquito Aedes aegypti. The biting deterrence of the oil produced a proportion not biting (PNB) value of 0.62 at 10 µg/cm2 as compared with 0.86 of control DEET (N,N-diethyl-3-methylbenzamide) at a standard dose of 25 nmol/cm2. Among individually selected compounds present in the oil (α-bisabolol, β-caryophyllene, α-humulene, and caryophyllene oxide), only α-bisabolol produced a PNB value of 0.80, equivalent to DEET at 25 nmol/cm2, whereas the others were not repellent. The artificial mixture (AMES-1) of these four selected compounds produced a relatively high PNB value of 0.80. The repellent activity measured by minimum effective dosage (MED) for α-bisabolol and α-humulene produced MED values of 0.094 and 0.104 mg/cm2, respectively, as compared with 0.023 mg/cm2 of DEET. The leaf essential oil, the artificial mixture (AMES-1), and other binary and tertiary combinations of major compounds showed no repellent activity. In addition, morpho-anatomical features of the leaf are provided for correct identification of the species.

Abstract
Traditional medicinal plants are widely used as immunomodulatory medicines that help improve health. A total of 50 different plants used for the treatment of toxicity were screened for their in vivo protective effects. Flies were fed a standard cornmeal-yeast medium (control group) or the standard medium containing medicinal plant extracts (experimental groups). Assessment of the survival rate was performed by feeding flies with toxic compounds. Gut epithelial cells were analyzed for cell proliferation and death by green fluorescent protein antibodies and 7-aminoactinomycin D staining under the microscope. The expression of antimicrobial peptides (AMPs) was evaluated by the quantitative polymerase chain reaction and the results revealed that after feeding the flies with toxic compounds, aqueous extracts from Codonopsis pilosula (Franch.) Nannf (C. pilosula), Saussurea lappa (Decne.) C.B.Clarke (S. lappa), Imperata cylindrica Beauv.var.major (Nees) C.E. Hubb. (I. cylindrical var. major) and Melia toosendan Sied. Et Zucc. (M.toosendan) increased the fly survival rate, reduced epithelial cell death and improved gut morphology. In addition, C. pilosula extracts induced the antimicrobial peptide levels (Dpt and Mtk) following treatment with sodium dodecyl sulfate (SDS). However, these extracts were not observed to increase SDS-induced cell proliferation in vivo. These results indicate that there are strong protective effects in extracts of C. pilosula, S. lappa, I. cylindrical var. major and M. toosendan on Drosophila intestinal cells among 50 medicinal plants.

Abstract
Evidences are accumulating that extract of Acanthopanax senticosus Harms (ASH; syn Eleutherococcus senticosus [Rupr. & Maxim.] Maxim), a shrub native to Northeastern Asia, has antiinflammatory effects. In this study, we examined prophylactic and therapeutic effects of ASH extract (ASHE) on rheumatoid arthritis using collagen-induced arthritis (CIA) mouse model. Acanthopanax senticosus Harms extract was administered before the onset of arthritis in the prophylaxis model. In the therapeutic model, ASHE was administered after the onset of arthritis with or without anti-TNF-α antibody. The ASHE treatment showed efficacy before onset of CIA but there was no effect after CIA was established. The ASHE treatment delayed the onset and decreased severity of CIA. In vitro examinations showed that ASHE is an antioxidant and that ASHE suppresses TNF-α and interleukin-6 production in human peripheral blood mononuclear cells. The combination therapy with ASHE and anti-TNF-α antibody reduced the severity of arthritis compared with anti-TNF-α antibody alone. The present study shows that ASHE has prophylactic effect against CIA and support therapeutic effect of anti-TNF-α antibody. © 2014 The Authors.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Aanthopanax senticosus (A. senticosus) Harms is a classical adaptogenic agent used in China. It has been applied as an analeptic aid to improve weakened physical status. However, little is known about the effects of A. senticosus on inflammatory disease processes. MATERIALS AND METHODS Flies fed with standard cornmeal-yeast medium were used as controls, and the treatment groups contained 10% of A. senticosus aqueous extracts (root or fruit) in standard medium. Survival rate was performed by feeding a vial containing five layers of filter paper hydrated with 5% sucrose solution contaminated with pathogenic or toxic compounds. Imaging of the guts was viewed under the microscope. Death cells were detected by 7-AAD staining. RESULTS The A. senticosus extract improved the survival rate, attenuated the death of intestinal epithelial cells, promoted the expression of antimicrobial peptide genes, and decreased the formation of melanotic masses. Moreover, our results indicated that the protective effect of fruit is much higher than that of root extracts. CONCLUSIONS A. senticosus extracts have a protective effect on Drosophila gut immunity and stress response, and may contribute to the prevention of inflammatory diseases induced by pathogenic and toxic compounds.

Abstract
AbstractThere is a current trend to support pet health through the addition of natural supplements to their diet, taking into account the high incidence of medical conditions related to their immune system and gastrointestinal tract. This study investigates effects of the plant Eleutherococcus senticosus as a dietary additive on faecal microbiota, faecal characteristics, blood serum biochemistry and selected parameters of cellular immunity in healthy dogs. A combination of the plant with the canine-derived probiotic strain Lactobacillus fermentum CCM 7421 was also evaluated. Thirty-two dogs were devided into 4 treatment groups; receiving no additive (control), dry root extract of E. senticosus (8 mg/kg of body weight), probiotic strain (108 CFU/mL, 0.1 mL/kg bw) and the combination of both additives. The trial lasted 49 days with 14 days supplementation period. Results confirm no antimicrobial effect of the plant on the probiotic abundance either in vitro (cultivation test) or in vivo. The numbers of clostridia, lactic acid bacteria and Gram-negative bacteria as well as the concentration of serum total protein, triglyceride, glucose and aspartate aminotransferase were significantly altered according to the treatment group. Leukocyte phagocytosis was significantly stimulated by the addition of probiotic while application of plant alone led to a significant decrease.

Anal Chim Acta 2012; 717:61-6. [PMID: 22304816 DOI: 10.1016/j.aca.2011.12.045] [Citation(s) in RCA: 54] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2011] [Revised: 12/19/2011] [Accepted: 12/21/2011] [Indexed: 12/13/2022]
Abstract
The direct electron transfer of superoxide dismutase (SOD) was greatly facilitated by sodium alginate (SA) sol-gel film with the formal potential of 0.14 V, which was just located between O(2)(•-)/O(2) and O(2)(•-)/H(2)O(2). The preparation of the SOD/SA modified electrode was simple without any mediators or promoters. Based on bimolecular recognition for specific reactivity of SOD/SA toward O(2)(•-), the SOD modified electrode was utilized to measure O(2)(•-) with good analytical performance, such as low applied potential (0 V), high selectivity (no obvious interference), wide linear range (0.44-229.88 μM) and low detection limit (0.23 μM) in pH 7.0 phosphate buffer solution. Furthermore, it could be successfully exploited for the determination of O(2)(•-) released from living cells directly adhered on the modified electrode surface. Thus, the proposed O(2)(•-) biosensor, combining with the properties of SA sol-gel film, provided a novel approach for protein immobilization, direct electron transfer study of the immobilized protein and real-time determination of O(2)(•-) released from living cells.

Abstract
In this work, direct electron transfer of cytochrome c (cyt. c)--a model for studying the electron transfer of enzymes is achieved at hexagonal ZnO nanosheets by one-step electrodeposition. UV-vis spectra and electrochemical data demonstrate that such ZnO nanosheets can supply a bio-compatible surface to keep the bioactivity of cyt. c. The redox formal potential (E(0)') of cyt. c is estimated to be 338.2+/-4.3 mV (vs. AgAgCl) at the nanostructured ZnO surface. This value is much more positive than those of enzymes previously obtained at other metal oxides and zeolite surfaces. Experiment data show, under the optimized potential of 0.0 V (vs. AgAgCl), the electrochemical determination of H(2)O(2) is free from not only anodic interferences like ascorbic acid (AA) and dopamine (DA), but also a cathodic interference-O(2). Such an excellent selectivity enable the present H(2)O(2) biosensor determine the extracellular H(2)O(2) released from living human hepatoma cells.

Abstract
The purpose of this prospective randomized study was to investigate the effects of the extract of Acanthopanax senticosus (AS extract), a widely used oriental herb, on bone remodeling and bone mineral density in Korean postmenopausal women. A total of 81 postmenopausal women with osteopenia or osteoporosis, an age of less than 65 years, were enrolled in the study. Subjects were randomly assigned to two groups: (1) the control group (n = 40), calcium intake (500 mg per day), and (2) the treatment group (n = 41), calcium (500 mg per day) plus AS extract (3 g per day). After treatment with AS extract for 6 months, the AS extract group showed a significant increase in serum osteocalcin levels compared with the control group (P = 0.041). However, no significant changes in bone mineral density were observed by dual-energy X-ray absorptiometry (DXA). AS extract was generally well tolerated, and no differences were observed between the two groups in terms of adverse events. This study suggests that AS extract supplementation may have beneficial effects on bone remodeling in Korean postmenopausal women and that it has no significant adverse events.

Abstract
AIM OF THE STUDY In this study, we evaluated protective effect of Acanthopanax senticosus extract (ASE) and a possible signaling pathway involved during endotoxic shock induced by intraperitoneal injection lipopolysaccharide (LPS) and D-galactosamine (D-GalN) in BALB/c mice. MATERIALS AND METHODS Mice were intraperitoneal administrated with ASE (100, 200 or 400mg/kg) prior to injection of 50 microg/kg LPS and 1g/kg D-GalN. The levels of tumor necrosis-alpha (TNF-alpha) and interleukin-10 (IL-10) in serum and liver. Nitric oxide (NO) production in serum and inducible nitric oxide synthase (iNOS) protein level were investigated. Nuclear factor-kappa B (NF-kappaB) activation in liver was determined. Furthermore, we evaluated the effect of ASE pretreatment on infiltration of inflammatory cells into the heart, liver and lung of mice. RESULTS Treatment of mice with ASE prior to LPS/D-GalN injection significantly improved the survival rate. ASE pretreatment inhibited the elevation of TNF-alpha in serum and liver. ASE also decreased iNOS level in liver and the overproduction of nitric oxide (NO) in serum. In addition, IL-10 levels in serum and liver were markedly enhanced. ASE pretreatment inhibited NF-kappaB activation in liver of mice. Moreover, infiltration of inflammatory cells into the heart, liver and lung of mice was also attenuated by ASE pretreatment. CONCLUSIONS These results suggested that ASE protected mice against LPS/D-GalN-induced endotoxic shock involving inhibition of NF-kappaB activation, which caused down-regulation of TNF-alpha and involved up-regulation of IL-10. Acanthopanax senticosus may thus prove beneficial in the prevention of endotoxic shock.
