It was established a method based on Raman spectroscopy in order to control the content and concentration of homeopathic dilutions. Dilutions of a tincture of Bryonia Dioica in ethanol were prepared and investigated by Raman spectroscopy. The Raman line at 881 cm-1 was found to depend linearly versus the concentration of Bryonia Dioica. This permits to obtain a calibration curve that may be used to determine the concentration of Bryonia Dioica in ethanol. The method may be extended to determine the concentration of various homeopathic dilutions.

Isolates of Didymella bryoniae (Auersw.) Rehm, causal agent of gummy stem blight on cucurbits, developed insensitivity to azoxystrobin in the eastern United States 2 years after first commercial use in 1998. Baseline sensitivity of this fungus to azoxystrobin has never been reported. The objectives were to compare baseline sensitivities of D. bryoniae from South Carolina and other locations to sensitivities of isolates exposed to azoxystrobin for one or more seasons, and to compare sensitivity in vitro and in vivo. Sixty-one isolates of D. bryoniae collected before 1998 were sensitive. Median EC50 was 0.055 mg L(-1) azoxystrobin (range 0.005 to 0.81). Forty isolates collected after exposure during 1998 also were sensitive. Fifty-three of 64 isolates collected in South and North Carolina between 2000 and 2006 were insensitive to 10 mg L(-1) azoxystrobin. Sensitive and insensitive isolates were distinguished by disease severity on Cucumis melo L. seedlings treated with azoxystrobin (20 or 200 mg L(-1)). An azoxystrobin baseline sensitivity distribution was established in vitro for isolates of D. bryoniae never exposed to strobilurins. Baseline values were comparable with those of other ascomycetes. Insensitive isolates were found in fields with a history of strobilurin applications. An in vivo method distinguished sensitive and insensitive isolates. Copyright 2009 Society of Chemical Industry.

Didymella bryoniae (anamorph Phoma cucurbitacearum) is an ascomycete that causes gummy stem blight, a foliar disease that occurs on cucurbits in greenhouses and fields throughout the world. In a previous study using RAPD analysis, little genetic diversity was found among isolates of D. bryoniae from New York and South Carolina, USA. Here we report the use of amplified fragment length polymorphism (AFLP) analysis to assess the genetic variation within a worldwide collection of D. bryoniae, 102 field and greenhouse isolates from ten states in the USA (California, Delaware, Florida, Georgia, Indiana, Maryland, Michigan, Oklahoma, South Carolina, and Texas) and seven other countries (Australia, Canada, China, Greece, Israel, Sweden, and The Netherlands) were examined. Seven different AFLP primer-pair combinations generated 450 bands, of which 134 were polymorphic (30%). Using cluster analysis, two groups and a total of seven subgroups were delineated. Representative isolates varied in their virulence on muskmelon and watermelon seedlings, but the degree of virulence was not strongly associated with AFLP groupings. However, isolates from the northern USA grouped separately from isolates originating from the southern USA.

Didymella bryoniae is an important pathogen of cucurbits worldwide. Virulence factors of D. bryoniae were investigated in regard to fungal growth and the production of cell wall-degrading enzymes, polygalacturonase (PG), pectate lyase (PL), pectin lyase (PNL), β-galactosidase (β-Gal) and cellulase (Cx). Virulence levels of five D. bryoniae isolates were determined by the severity of inoculated cantaloupe fruit decay. The highly virulent isolates had more mycelial growth than the moderately virulent isolates in different media. PG activities produced by the highly virulent isolates in shake cultures and in decayed fruit were greater than those of the moderately virulent isolates. PNL, but not PL, in decayed fruit was higher with the highly virulent isolates compared to the moderately virulent ones. The highly virulent isolates showed higher Cx activity than the moderately virulent ones in decayed fruit and in fruit tissue shake culture. β-Gal activities of the highly virulent isolates in pectin shake culture and in decayed fruit were greater than those of the two moderately virulent isolates although fruit also produced β-Gal. Protein analysis showed two fungal β-Gal isozymes in decayed fruit compared to those of healthy fruit. Correlation analysis indicated that the activities of PG, PNL, β-Gal and Cx in cultures and in decayed fruit positively correlated with fungal growth and fruit decay severity. The results of this study suggest that PG, PNL, β-Gal, and Cx appear to be virulence factors of D. bryoniae in cantaloupe decay with PG and β-Gal as the most predominant fruit decay enzymes.

Merck, C C; Sonnenwald, B; Rollwage, H
1989-08-01
The general principles of homeopathic therapy are described together with a number of homeopathic drugs used for the treatment of acute bovine mastitis. Fifty cows with acute mastitis were used in the study. The initial treatment comprised aconitum D 4, phytolacca D 1 and bryonia D 4. In subsequent treatments phytolacca D 1, bryonia D 4 and lachesis D 8 either singly or in combination were used; mercurius solubilis D 4 was also used. Encouraging results, especially in the treatment of cases of E.coli mastitis, were achieved.

Dowsing is a method of problem-solving that uses a motor automatism, amplified through a pendulum or similar device. In a homeopathic context, it is used as an aid to prescribing and as a tool to identify miasm or toxin load. A randomized double-blind trial was conducted to determine whether six dowsing homeopaths were able to distinguish between Bryonia in a 12c potency and placebo by use of dowsing alone. The homeopathic medicine Bryonia was correctly identified in 48.1% of bottle pairs (n=156; 95% confidence interval 40.2%, 56.0%; P=0.689). These results, wholly negative, add to doubts whether dowsing in this context can yield objective information.

To determine the elements in Bryonia alba L. roots, collected from the Crimean Peninsula region in Ukraine. Dry ashing was used as a flexible method and all elements were determined using atomic absorption spectrometry (AAS) equipped with flame and graphite furnace. The average concentrations of the determined elements, expressed as mg/100 g dry weight of the sample, were as follow: 13.000 for Fe, 78.000 for Si, 88.000 for P, 7.800 for Al, 0.130 for Mn, 105.000 for Mg, 0.030 for Pb, 0.052 for Ni, 0.030 for Mo, 210.000 for Ca, 0.130 for Cu, 5.200 for Zn, 13.000 for Na, 1170.000 for K, 0.780 for Sr, 0.030 for Co, 0.010 for Cd, 0.010 for As, and 0.010 for Hg. Toxic elements such as Cd and Pb were also found but at very low concentration. Among the analyzed elements, K was the most abundant followed by Ca, Mg, P, Si, Fe, Na, and Zn, whereas Hg, As, Cd, Co, Mo, and Pb were found in low concentration. The results suggest that the roots of Bryonia alba L. plant has potential medicinal property through their high element contents present. Moreover, it showed that the AAS method is a simple, fast, and reliable for the determination of elements in plant materials. The obtained results of the current study provide justification for the usage of such fruit in daily diet for nutrition and for medicinal usage in the treatment of various diseases.

A specific insertion of a solo-LTR characterizes the Y-chromosome of Bryonia dioica (Cucurbitaceae).
Oyama, Ryan K; Silber, Martina V; Renner, Susanne S
2010-06-14
Relatively few species of flowering plants are dioecious and even fewer are known to have sex chromosomes. Current theory posits that homomorphic sex chromosomes, such as found in Bryonia dioica (Cucurbitaceae), offer insight into the early stages in the evolution of sex chromosomes from autosomes. Little is known about these early steps, but an accumulation of transposable element sequences has been observed on the Y-chromosomes of some species with heteromorphic sex chromosomes. Recombination, by which transposable elements are removed, is suppressed on at least part of the emerging Y-chromosome, and this may explain the correlation between the emergence of sex chromosomes and transposable element enrichment. We sequenced 2321 bp of the Y-chromosome in Bryonia dioica that flank a male-linked marker, BdY1, reported previously. Within this region, which should be suppressed for recombination, we observed a solo-LTR nested in a Copia-like transposable element. We also found other, presumably paralogous, solo-LTRs in a consensus sequence of the underlying Copia-like transposable element. Given that solo-LTRs arise via recombination events, it is noteworthy that we find one in a genomic region where recombination should be suppressed. Although the solo-LTR could have arisen before recombination was suppressed, creating the male-linked marker BdY1, our previous study on B. dioica suggested that BdY1 may not lie in the recombination-suppressed region of the Y-chromosome in all populations. Presence of a solo-LTR near BdY1 therefore fits with the observed correlation between retrotransposon accumulation and the suppression of recombination early in the evolution of sex chromosomes. These findings further suggest that the homomorphic sex chromosomes of B. dioica, the first organism for which genetic XY sex-determination was inferred, are evolutionarily young and offer reference information for comparative studies of other plant sex chromosomes.

" Arnica montana is a popular homoeopathic treatment with potential haemostatic and anti-inflammatory properties. A homoeopathic combination of A. montana and Bryonia alba was used in aortic valve surgery to evaluate its effectiveness in reducing bleeding, inflammation, pain and myocardial ischaemia. One day before surgery, 92 adult patients were randomly assigned to a double-blind parallel trial with either homoeopathic granules or a matching placebo until 4 days after surgery. The primary outcome was the volume of blood/liquid in the drains at their removal. The secondary outcomes included postoperative blood/liquid losses at 12 and 24 h as well as C-reactive protein (CRP), pain, temperature and plasma troponin Ic. At 12 h and 24 h after surgery, then at drain removal, blood losses in homoeopathy and placebo groups were not statistically significant (362 +/- 218, 520 +/- 269 and 640 +/- 297 ml vs. 456 +/- 440, 620 +/- 477 and 796 +/- 717 ml; P= 0.19, 0.23 and 0.35, respectively). The statistical modelling did not show significantly different patterns of CRP, troponin and body temperature changes or of pain perception. The number of transfused packed red cells was not significantly different either (P= 0.58). Two patients from each group died during the study period and the number of serious adverse events was not statistically different (six in homoeopathy vs. 10 in placebo groups; Fisher's exact test P= 0.41). In the study setting, there was no evidence of effects of A. montana and B. alba combination on bleeding, inflammation, pain or myocardial ischaemia.

Mechanosensing and signaltransduction in tendrils
NASA Astrophysics Data System (ADS)
Engelberth, Jürgen
2003-10-01
The perception of thigmic stimuli is a widespread phenomenon among plants with decisive meaning for the ability to survive. Beside a general sensitivity for mechanical stimuli many plants have evolved specialized organs with highly developed mechanisms to perceive and transduce the applied forces. Tendrils of Bryonia dioica and Pisum sativum have been chosen to study the effects of mechanical stimulation on plant physiology. Both types of tendrils, although exhibiting different morphology, respond to such a stimulus with a rapid coiling response to the dorsal side of the organ within minutes. The actual perception of the stimulus is most likely coupled to the cytoskeleton serving as the mediator between the physical stimulus and the biochemical response. Drugs affecting the status of the cytoskeleton were used to get more insights into this specific process. The results indicate that microtubuli (MT) play the most important role in the perception of thigmic stimuli in tendrils. Colchicine-mediated disruption of MT lead to total inhibition of the response to the thigmic stimulus in tendrils of Pisum and to a reduced response in Bryonia. Alamethicin, an ionophore that can mimic action potentials in membranes, was able to bypass this inhibition suggesting a direct involvement of MT in depolarization of the membranes. Auxin, however, which is also supposed to be involved in the regulation of the coiling response, failed to bypass colchicine-dependent inhibition. Vinblastine, another microtubule depolimerizing agent, did induce tendril coiling in Pisum without further stimulation. Application of taxol and other MT-stabilizing drugs as well as disruption of the actin network did not affect the coiling response of tendrils. In Pisum indole-3-acetic acid (IAA) is induced after mechanical stimulation during the coiling response, but not jasmonic acid. A further consequence of mechanical stimulation is the induction of an oxidative burst and an increase in soluble sugar. A model is presented integrating these results and might serve as a common basis for the understanding of the perception of mechanical stimuli.

Aims The efficacy of homeopathy is still under debate. The objective of this study was to assess the efficacy of homeopathic treatment (Arnica montana 5 CH, Bryonia alba 5 CH, Hypericum perforatum 5 CH and Ruta graveolens 3 DH) on cumulated morphine intake delivered by PCA over 24 h after knee ligament reconstruction. Methods This was an add-on randomized controlled study with three parallel groups: a double-blind homeopathic or placebo arm and an open-label noninterventional control arm. Eligible patients were 18–60 years old candidates for surgery of the anterior cruciate ligament. Treatment was administered the evening before surgery and continued for 3 days. The primary end-point was cumulated morphine intake delivered by PCA during the first 24 h inferior or superior/equal to 10 mg day−1. Results One hundred and fifty-eight patients were randomized (66 in the placebo arm, 67 in the homeopathic arm and 25 in the noninterventional group). There was no difference between the treated and the placebo group for primary end-point (mean (95% CI) 48% (35.8, 56.3), and 56% (43.7, 68.3), required less than 10 mg day−1 of morphine in each group, respectively). The homeopathy treatment had no effect on morphine intake between 24 and 72 h or on the visual analogue pain scale, or on quality of life assessed by the SF-36 questionnaire. In addition, these parameters were not different in patients enrolled in the open-label noninterventional control arm. Conclusions The complex of homeopathy tested in this study was not superior to placebo in reducing 24 h morphine consumption after knee ligament reconstruction. What is already known about this subject The efficacy of homeopathy is still under debate and a recent meta-analysis recommended further randomized double-blind clinical trials to identify any clinical situation in which homeopathy might be effective. What this study adds The complex of homeopathy tested in this study (Arnica montana 5 CH, Bryonia alba 5 CH, Hypericum perforatum 5 CH and Ruta graveolens 3 DH) is not superior to placebo in reducing 24 h morphine consumption after knee ligament reconstruction.

Many foods are known to have not only nutritive and taste values but also medicinal effects. In Egypt, many medicinal foods have been used for the prevention and treatment of various diseases since ancient. However, in most cases, their effective constituents as well as the mechanism of action remained uncharacterized. In the course of our characterization studies on Egyptian medicinal foods and plants, cucurbitane-type triterpene and related compounds such as cucurbitacin E from the fruit of Citrullus colocynthis and the roots of Bryonia cretica were found to show anti-proliferation effects. We therefore synthesized a biotin-linked cucurbitacin E to isolate target proteins based on affinity for the molecule. As a result, cofilin, which regulates the depolymerization of actin, was isolated and suggested to be a target.

The development of a real-time continuous analytical platform for the pathogen detection is of great scientific importance for achieving better disease control and prevention. In this work, we report a rapid and recyclable microfluidic bioassay system constructed from oligonucleotide arrays for selective and sensitive continuous identification of DNA targets of fungal pathogens. We employ the thermal denaturation method to effectively regenerate the oligonucleotide arrays for multiple sample detection, which could considerably reduce the screening effort and costs. The combination of thermal denaturation and laser-induced fluorescence detection technique enables real-time continuous identification of multiple samples (<10 min per sample). As a proof of concept, we have demonstrated that two DNA targets of fungal pathogens (Botrytis cinerea and Didymella bryoniae) can be sequentially analyzed using our rapid microfluidic bioassay system, which provides a new paradigm in the design of microfluidic bioassay system and will be valuable for chemical and biomedical analysis.

2007-01-01
Among the compounds discussed for anti-microbial and anti-fungal use allicin (allylthiosulfinate, diallyl disulfide-S-monoxide), an active ingredient of garlic, has attracted considerable attention. The objective of this study is to determine the antifungal activity of a local garlic ecotype (Voghiera) extracts against different pathogens. Primary screening was carried out by the agar plates technique using ethanol garlic extract at four final concentrations against the following organisms: Alternaria alternata, Aspergillus spp., Colletotrichum acutatum, Didymella bryoniae, Fusarium culmorum, Fusarium avenaceum, Fusarium gramineareum, Gliocladium roseum 47, Pythium splendens, Rhizoctonia solani, Sclerotium rolfsii, Stemphylium vesicarium, Trichoderma longibranchiatum, and Botrytis cinerea. Secondary screening was carried out using a lyophilized and a spray-dried preparation at different concentrations against the organisms selected for the high inhibition garlic effect in the primary screening and compared with the commercial fungicides mancozeb and iprodione. The best results were observed for the spray-dried garlic compound that showed a good fungicidal activity at the concentration of 1.5 g/10 mL while lyophilized garlic at the same concentration exhibited less inhibition activity against the four fungi analyzed in the second screening.

Background A critical analysis was made of cucurbit descriptions in Dioscorides' De Materia Medica, Columella's De Re Rustica and Pliny's Historia Naturalis, works on medicine, agriculture and natural science of the 1st century ce, as well as the Mishna and Tosefta, compilations of rabbinic law derived from the same time period together with cucurbit images dating from antiquity including paintings, mosaics and sculpture. The goal was to identify taxonomically the Mediterranean cucurbits at the time of the Roman Empire. Findings By ancient times, long-fruited forms of Cucumis melo (melon) and Lagenaria siceraria (bottle gourd) were selected, cultivated and used as vegetables around the Mediterranean and, in addition, bottle-shaped fruits of L. siceraria were employed as vessels. Citrullus lanatus (watermelons) and round-fruited forms of Cucumis melo (melons) were also consumed, but less commonly. A number of cucurbit species, including Bryonia alba, B. dioica, Citrullus colocynthis and Ecballium elaterium, were employed for medicinal purposes. No unequivocal evidence was found to suggest the presence of Cucumis sativus (cucumber) in the Mediterranean area during this era. The cucumis of Columella and Pliny was not cucumber, as commonly translated, but Cucumis melo subsp. melo Flexuosus Group (snake melon or vegetable melon). PMID:17932073

The Canova Method (CM) is a homeopathic medicine indicated for the treatment of patients with cancer and for pathologies that involve a depressed immune system, such as AIDS. This product is composed of homeopathic dilutions of Aconitum napellus, Arsenicum album (arsenic trioxide), Bryonia alba, Lachesis muta venom and Thuya occidentalis. It stimulates the immune system by activating macrophages. Activated macrophages stimulate the lymphocytes so that they increase their cytotoxic action in response to tumoral growth or infection. Given that the CM stimulates and accelerates the activity of macrophages and lymphocytes, we evaluated genotoxic effects induced in human lymphocytes treated with this homeopathic medication in vitro. Structural and numerical chromosomal aberrations were scored for the assessment of induced genotoxic effects, while the variation in mitotic index was considered as a monitor for induced cellular toxicity. The lymphocytes were cultivated for 24, 48 or 72 h in the following final concentrations of the medicinal composite CM: 4, 8 and 12%. Treatments with the CM did not affect mitotic indexes, nor did they provoke chromosomal aberrations, when compared with untreated controls. There was no cytotoxicity or genotoxicity at the chromosomal level.

11 fruit fly species captured at 47 sites in a natural forest area at Cooloola (south-east Queensland) revealed specific patterns of spatial abundance. Although all species were collected throughout the study area, D. bryoniae, D. mayi, D. neohumeralis and D. tryoni were more prevalent (average number caught per trap) in the open Eucalypt forest than the rainforest, whereas C. aequalis, D. absonifacies and D. endiandrae were more prevalent in the rainforest. D. cacuminatus, D. choristus, D. quadratus and D. signatifrons were equally prevalent throughout both forest types. Fly numbers were not distributed randomly throughout the trap sites. The clumped dispersion patterns seemed to be species specific as assessed and summarised by Taylor's Power Law. The exponent (b) relating mean spatial abundance to its variance ranged from 1.6-5.11 for the 11 species captured. Changing patterns of trap catches from one sampling period to another were analysed using correlograms for the 6 most abundant species (D. tryoni, D. neohumeralis, D. endiandrae, C. aequalis, D. cacuminatus and D. mayi). These revealed changing patterns of relative spatial abundance which can be related, in part, to changing population abundance levels. The various spatial patterns recognised are related to each species movement, breeding and feeding behaviour. It is proposed that flies migrate into the rainforest area from distant locations and that the rainforest habitat is an important adult feeding site.

Osteoarthritis (OA) is a common cause of chronic low-back pain (CLBP) and can be managed with drug therapy and physiotherapy. Homeopathic remedies may assist managing OA; however, research that supports their effectiveness is limited. The study aimed to investigate the efficacy of a homeopathic complex in combination with physiotherapy in treating CLBP due to OA. The study was a 6-wk, randomized, double-blind, placebo-controlled pilot. The study took place in a private physiotherapy practice in Gauteng, South Africa. The participants were 30 males and females, aged 45-75 y, who were receiving physiotherapy treatment for OA of the lumbar spine from a therapist in private practice. The intervention and control groups both received standard physiotherapy treatment-massage, thermal therapy, and joint mobilization-every 2 wk. In addition, the treatment group received a homeopathic complex-6cH each of Arnica montana, Bryonia alba, Causticum, Kalmia latifolia, Rhus toxicodendron, and Calcarea fluorica. The control group a received a placebo. The primary measure was a visual analogue scale (VAS) for pain. Secondary outcome measures included the Oswestry Disability Index (ODI), an evaluation of each patient's range of motion (ROM) of the lumbar spine, and a determination of each patient's need for pain medication. Intergroup analysis revealed that the treatment group significantly outperformed the control group with regard to pain, daily functioning, and ROM. No difference existed between the groups, however, in the need for conventional pain medication. The study was too small to be conclusive, but results suggest the homeopathic complex, together with physiotherapy, can significantly improve symptoms associated with CLBP due to OA.

We have previously demonstrated that ADAPT-232, a fixed combination of adaptogenic substances derived from Eleutherococcus senticosus root extract, Schisandra chinensis berry extract, Rhodiola rosea root extract stimulated the expression and release of neuropeptide Y (NPY) and molecular chaperone Hsp72 from isolated human neurolgia cells. Both of these mediators of stress response are known to play an important role in regulation of neuroendocrine system and immune response. We further demonstrated that ADAPT-232 induced release of Hsp70 is mediated by NPY, suggesting an existence of NPY-mediated pathway of activation of Hsp72 release into the blood circulation system. The objective of this study was to determine whether this pathway is common for adaptogens and whether NPY and/or Hsp72 can be considered as necessary specific biomarkers for adaptogenic activity. The release of NPY and Hsp72 from neuroglia cells in response to treatment with various plant extracts (n=23) including selected validated adaptogens, partly validated adaptogens, claimed but negligibly validated adaptogens and some other plant extracts affecting neuroendocrine and immune systems but never considered as adaptogens was measured using high throughput ELISA techniques. We demonstrated that adaptogens, e.g. R. rosea, S. chinensis and E. senticosus stimulate both NPY and Hsp70 release from neuroblastoma cells, while tonics and stimulants have no significant effect on NPY in this in vitro test. In the groups of partly validated adaptogens the effect of Panax ginseng and Withania somnifera was not statistically significant both on NPY and Hsp70 release, while the activating effect of Bryonia alba and Rhaponticum cartamoides was significant only on Hsp70. In contrast, all tested non-adaptogens, such as antiinflammatoty plant extracts Matricaria recutita, Pelargonium sidoides, Hedera helix and Vitis vinifera significantly inhibit Hsp70 release and have no influence on NPY release from neuroblastoma cells. These experiments were further validated using primary human neurons and confirmed that adaptogens activate the release of both NPY and Hsp70, while tested non adaptogens were inactive in NPY assay and inhibit the release of Hsp70. Taken together, our data demonstrates for the first time that neuropeptide Y and heat shock protein Hsp70 can be used as molecular biomarkers for adaptogenic activity. Copyright © 2013 Elsevier GmbH.
