    The hypotensive effects of the water extract of Marrubium vulgare L. and Foeniculum vulgare L. were investigated in spontaneously hypertensive rats (SHR) and in normotensive Wistar-Kyoto rats (WKY). Oral administration of Marrubium or Foeniculum extract lowered the systolic blood pressure of SHR but not of WKY. In SHR, Foeniculum but not Marrubium treatment increased water, sodium and potassium excretion. Ex vivo as well as in vitro, Marrubium extract inhibited the contractile responses of rat aorta to noradrenaline and to KCl (100 mM). Inhibition was greater in aorta from SHR compared to WKY and was not affected by the NO synthase inhibitor N-nitro-L-arginine. Vascular effects of Foeniculum extract were less pronounced than those of Marrubium and were blocked by N-nitro-L-arginine. These results indicate that hypotensive activity of Marrubium and Foeniculum extracts seems to be mediated through different pathways: Foeniculum appeared to act mainly as a diuretic and a natriuretic while Marrubium displayed vascular relaxant activity.

The M27-T technique allowed us to determine the Minimum Inhibitory Concentrations (MICs of different extracts. Therefore, the test’s results showed that the all samples were clearly different in terms of antimicrobial activities. All extracts of Foeniculum vulgare showed the most activity on all the microorganisms tested. The most significant and active extract under study were methanol and ethyl acetate on all the bacteria tested in comparaison to the hexane and aqueous extracts. On the other hand, the results of antimicrobial activity of aqueous extract were more compelling than the hexane and dichloromethane extracts when used on Candida albicans (ATCC and CBS (MIC = 0,78 mg mL-1. It then appear that C. albicans ATCC is the least susceptible microorganisms to the ethyl acetate extract. The chloramphenicol, amoxicillin and amphotericin B were used as standard antibiotics to carry this study."

    Full Text Available This study was conducted to determine the insecticidal activity of essential oils from Fennel, Foeniculum vulgare (Apiaceae, and Summer savory, Satureja hortensis (Lamiaceae, against two stored-product insects. Essential oils from two species of plants were obtained by Clevenger-type water distillation and their fumigant toxicities were tested against adults of the wheat weevil, Sitophilus granarius and rice weevil, Sitophilus oryzae (Curculionidae. The mortality was determined after 24 and 48 hrs from beginning of exposure. LC50 values of each essential oil were estimated for each insect species. Fumigation bioassays revealed that essential oils from two plants had strong insecticidal activity on experimental insects. LC50 values indicated that S. granarius was more susceptible than S. oryzae to essential oils at the exposure time 24 and 48 hrs. The mortality effect of S. hortensis oil was lower than F. vulgare oil. The LC50 values decreased with the duration of exposure to the essential oil concentrations. In all case, responses varied according to plant material, concentration, and exposure time. These results indicated that essential oils from S. hortensis and F. vulgare could be applicable to the management of stored product insects to decrease ecologically detrimental effects of utilization synthetic insecticides.

  11. Effect of gamma - irradiation on the volatile flavor profile of fennel (foeniculum vulgare mill.) from Pakistan

    International Nuclear Information System (INIS)

    The volatile flavor compounds of non-irradiated and 1, 5, 10 and 20 kGy gamma-irradiated seeds of fennel (Foeniculum vulgare Mill.) from Pakistan were isolated by simultaneous distillation-extraction (SDE) and were analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 82 compounds were identified in the non irradiated fennel, with EAnethole (36.74 percentage), Estragole (26.31 percentage), and β-Limonene (15.99 percentage) as the major compounds. The irradiation doses caused slight variations in the number and contents of the volatile components. Though several volatile compounds showed increase after Υ-irradiation, the contents of major compounds such as beta-Limonene and estrgole were decreased. The overall number of the volatile compounds showed increase up to the recommended irradiation doses of 10 kGy but their contents decreased. In general no major change was noted in the overall major flavor compounds of the subject spice. Therefore the application of Υ--irradiation is feasible without any significant qualitative or quantitative loss of volatile flavor compounds when exposed to 10 kGy Υ--irradiation. (author)

    Full Text Available Methanolic extract of dried Fennel (Foeniculum vulgare Miller seeds was analyzed for the presence of bioreactive compounds: ascorbate, riboflavin, tocopherol and polyphenols with potential antioxidant properties. The extract had low ascorbate (197.12+1.82µg, riboflavin (11.97+0.35µg and tocopherol (280.33+5.67µg/g dry seeds content. However the extract had high polyphenol content (16.506+0.32mg/g dry seeds. Antioxidant activity of the extract was determined by various mechanisms including DPPH free radical scavenging, metal induced protein and lipid oxidation inhibition and protection of DNA against H2O2 induced damage. Fennel had excellent free radical scavenging activity with IC50 2.1mg dry seed weight. IC50 observed for protection of proteins and lipids against metal ion induced oxidation is 2.1 and 2.5mg dry seed weight respectively. Extract equivalent to 0.5µg seeds is enough to protect DNA against H2O2 induced oxidation. The results suggest that polyphenols are the principal components responsible for high antioxidant potential of methanolic extract of fennel.

  17. The Possible Protective Role of Foeniculum vulgare Mill. Against Radiation-Induced Certain Biochemical Changes in Albino Rats

    International Nuclear Information System (INIS)

    This study was conducted to evaluate the modulating efficacy of prolonged oral administration of Foeniculum vulgare Mill. essential oil (FEO) against gamma irradiation-induced biochemical changes in male rats. Essential oil of Foeniculum vulgare Mill. was orally administrated at dose level of 250 mg/kg body wt/day for 21 days before irradiation and 7 days post exposure (6.5 Gy single dose). Rats exposed to ionizing radiation exhibited a potential elevation of serum aspartate aminotransferase (AST) and alkaline phosphatase (ALP) activities, bilirubin, urea and creatinine levels, lipid abnormalities, and an increase in tissue lipid peroxidation (LPO) and metallothioneins (MTs). On the other hand, noticeable drop in liver and kidney glutathione content and serum total protein, albumin and testosterone levels were recorded. Tissue organs displayed some changes in trace element concentrations, which may be due to the radiation ability to induce oxidative stress. The data obtained from rats treated with fennel oil before and after whole body gamma irradiation revealed significant modulation in the biochemical tested parameters and profound improvement in the activity of antioxidant status, glutathione and metallothioneins. The treatment of irradiated rats with fennel oil also appeared to be effective in minimizing the radiation-induced increase in lipid peroxidation as well as changes in essential trace elements in some tissue organs. In addition to its containing many chemical antioxidant constituents such as polyphenols, fennel was found to contain detectable concentrations of essential trace elements (Zn, Cu, Fe, Se, Mg, Mn and Ca) which may be involved in multiple biological processes as constituents of enzymes system including superoxide dismutase (Cu, Zn, Mn, SODs), oxide reductase, glutathione (GSP, GSH, GST), metallothionein MTs, etc. Overall, it could be concluded that Foeniculum vulgare Mill. essential oil exerts beneficial protective role against radiation

    Santa Cruz Island is the largest of the California Channel Islands and supports a diverse and unique flora which includes 9 federally listed species. Sheep, cattle, and pigs, introduced to the island in the mid-1800s, disturbed the soil, browsed native vegetation, and facilitated the spread of exotic invasive plants. Recent removal of introduced herbivores on the island led to the release of invasive fennel (Foeniculum vulgare), which expanded to become the dominant vegetation in some areas and has impeded the recovery of some native plant communities. In 2007, Channel Islands National Park initiated a program to control fennel using triclopyr on the eastern 10% of the island. We established replicate paired plots (seeded and nonseeded) at Scorpion Anchorage and Smugglers Cove, where notably dense fennel infestations (>10% cover) occurred, to evaluate the effectiveness of native seed augmentation following fennel removal. Five years after fennel removal, vegetative cover increased as litter and bare ground cover decreased significantly (P < 0.0001) on both plot types. Vegetation cover of both native and other (nonfennel) exotic species increased at Scorpion Anchorage in both seeded and nonseeded plots. At Smugglers Cove, exotic cover decreased significantly (P = 0.0001) as native cover comprised of Eriogonum arborescensand Leptosyne gigantea increased significantly (P < 0.0001) in seeded plots only. Nonseeded plots at Smugglers Cove were dominated by exotic annual grasses, primarily Avena barbata. The data indicate that seeding with appropriate native seed is a critical step in restoration following fennel control in areas where the native seed bank is depauperate.

    Full Text Available Bonde S. 2011. A biogenic approach for green synthesis of silver nanoparticles using extract of Foeniculum vulgare and its activity against Staphylococcus aureus and Escherichia coli. Nusantara Bioscience 3: 59-63. We report green synthesis of silver nanoparticles from extract of Foeniculum vulgare (fennel, saunf. The synthesis of silver nanoparticles was detected by changing color from green to brown after treatment with AgNO3 (1mM and the UV-visible spectrophotometer analysis showed the absorbance peak at about 427 nm, which indicates the synthesis of silver nanoparticles. Nanoparticle Tracking and Analysis (NTA by LM-20 was used for multi-parameter analysis, allowing for characterization of particle size and particle distribution of silver nanoparticles synthesized from extract of F. vulgare. NTA revealed the polydispersed nanoparticles in the range of 18-83 nm. Phytosynthesized silver nanoparticles showed antibacterial activity against the Staphylococcus aureus (ATCC-25923 and Escherichia coli (ATCC-39403. The silver nanoparticles also demonstrated remarkable antibacterial activity against two human pathogenic bacteria when used in combination with commercially available antibiotics. The bactericidal activity of the standard antibiotics was significantly enhanced in presence of silver nanoparticles against pathogenic bacteria, viz. E. coli-JM-103 (ATCC-39403 and S. aureus (ATCC-25923. Silver nanoparticles in combination with vancomycin showed maximum activity against E. coli (increase in fold area 5.76. and followed by S. aureus (1.08 and Gentamicin showed the maximum activity S. aureus (2.6 while E. coli (0.96.

    Dengue is a potentially fatal mosquito-borne infection with 50 million cases per year and 2.5 billion people vulnerable to the disease. This major public health problem has recurrent epidemics in Latin America and occurred recently in Cape Verde and Madeira Island. The lack of anti-viral treatment or vaccine makes the control of mosquito vectors a high option to prevent virus transmission. Essential oil (EO) constituents can affect insect's behaviour, being potentially effective in pest control. The present study evaluated the potential use of Foenicultm vulgare (fennel) EO in the control of the dengue vector Aedes aegypti. EOs isolated from fennel aerial parts collected in Cape Verde and from a commercial fennel EO of Portugal were analysed by NMR, GC and GC-MS. trans-Anethole (32 and 30%, respectively), limonene (28 and 18%, respectively) and fenchone (10% in both cases) were the main compounds identified in the EOs isolated from fennel from Cape Verde and Portugal, respectively. The larvicidal activity of the EOs and its major constituents were evaluated, using WHO procedures, against third instar larvae ofAe. aegypti for 24 h. Pure compounds, such as limonene isomers, were also assayed. The lethal concentrations LC50, C90 and LC99 were determined by probit analysis using mortality rates of bioassays. A 99% mortality of Ae. aegypti larvae was estimated at 37.1 and 52.4 µL L-1 of fennel EOs from Cape Verde and Portugal, respectively. Bioassays showed that fennel EOs from both countries displayed strong larvicidal effect against Ae. aegypti, the Cape Verde EO being as active as one of its major constituents, (-)-limonene.

    Spodoptera frugiperda (Smith 1797) (Lepidoptera: Noctuidae) is a major pest of maize, Zea mays L. Its control is often achieved through repeated applications per season of insecticides, which may lead to adverse effects on the ecosystem. Thus, the study of alternative methods with less environmental impact has expanded to include the use of essential oils. These oils are products of the secondary metabolism in plants, and their insecticidal activity has been widely demonstrated in populations of many pest insects. This study evaluated the insecticidal activities of essential oils from Eucalyptus staigeriana, Ocimum gratissimum, and Foeniculum vulgare on Spodoptera frugiperda. Gas chromatography–mass spectrometry profiles and contact toxicity of these oils as well as their sublethal effects on larvae and reproductive parameters in adults were evaluated. All three oils had sublethal effects on S. frugiperda; however, the oil of O. gratissimum showed the best results at all doses tested. These essential oils may have promise for control of S. frugiperda. PMID:26868417

  1. Irradiated Sewage Sludge for Production of Fennel (Foeniculum vulgare L.) Plants in Sandy Soil 2- Seed production, oil content, oil constituents and heavy metals in seeds

    International Nuclear Information System (INIS)

    Field experiment was conducted to study the impact of irradiated and non-irradiated sewage sludge applied to sandy soil on fennel plants (Foeniculum vulgare L.) productivity. In this regards, four rates of sewage sludge application were used (20, 40, 60 and 80 ton/ha) in addition to the mineral fertilizer treatment (control). Sandy soil amended with sewage sludge showed a promising effect on fennel seed yield. A linear gradual increase in seeds yield was observed as the sludge application rate increases. Seeds production increased by 41% to 308% over the control at 80t/ha application rate, for non-irradiated and irradiated sewage sludge treatments, respectively. Irradiated sewage sludge treatments showed higher fennel seed yield than non-irradiated sewage sludge treatments.Volatile oil percent exhibited no observable variation due to the use of sewage sludge. A few and limited fluctuations could be observed. However, total oil content (cc/plot) increased due to the increase in seeds yield. The magnitude of increase in volatile oil production in response to the sewage sludge application was parallel to the increase in seeds yield. The GLC measurements of the fennel volatile oil reveal that, the t-anethole is the predominant fraction. However, fenchone was detected in relatively moderate concentration. The applied sewage sludge treatment induced some variations in fennel volatile oil constituents. The t.anethole is relatively higher in volatile oil obtained from plants grown on sandy soil fertilized with non-irradiated sewage sludge than the one fertilized with irradiated sewage sludge or chemical fertilizer. In the meantime, the obtained increase in t.anethole was accompanied by a decline in fenchone content. Seeds heavy metals (Zn, Fe, Pb, Cd) were determined. Under all sludge application rates iron and zinc concentrations were in the normal plant concentration range whereas, Cd concentrations were traces.

    The study aims to investigate the protective effect of Pimpinella anisum oil on aspartame (ASP) which resulted in cerebellar changes. The rats were divided into four equal groups: Group 1: (control group): served as control animals. Group 2: control P. anisum oil received .5 mL/kg/d/b wt. once daily. Group 3 (ASP group): received daily 250 mg/kg/b wt. of ASP dissolved in distilled water and given orally to the animals by intra-gastric tube for 2 months. Group 4: received .5 mL/kg/b wt. of prophylactic P. anisum oil once daily, followed by ASP after 2 h for 2 months. The histopathological approach revealed marked changes in the Purkinje cells, myleinated nerve fibers and granular cells of ASP-treated animals. Some of these cells appeared with deeply stained cytoplasm. Ultrastructural examination showed Purkinje cells with dilated rough endoplasmic reticulum and condensed mitochondria. Granular cells appeared with less c nuclei and surrounded by dissolution of most Mossy rosettes structures. Most myelinated nerve fibers showed thickening of myelinated sheath and others showed splitting of their myelin sheath. The histopathological, immunohistochemical and ultrastructural alterations were much less observed in concomitant use of P. anisum oil with ASP. Cerebellar cortex is considered target areas of ASP neurotoxicity, while P. anisum oil, when used in combination with ASP displays a protective action against neurotoxicity.

    In order to evaluate the effects of different organic and biological fertilizers on quantity and quality of fennel essential oil, an experiment was conducted in a completely randomized block design with three replications. The experimental treatments included two organic (compost and vermicompost) and two biological (Pseudomonas putida and Azotobacter chroococcum) fertilizers, their all twin combinations (Ps. putida + A. chroococcum, Ps. putida + compost, Ps. putida + vermicompost, A. chroococcum + compost, A. chroococcum + vermicompost and compost + vermicompost) and control (non fertilized). There were significant differences between treatments in terms of seed essential oil percentage, essential oil yield; anethole, fenchone, limonene and straggle content in seed essential oil. Results showed that the highest and the lowest percentages of essential oil were obtained in control (2.9%) and A. chroococcum + vermicompost (2.2%) treatments, respectively. The highest essential oil yield (29.9 L ha{sup -}1) and anethole content of essential oil (69.7%) and the lowest contents of fenchone (6.14%), limonene (4.84%) and estragole (2.78%) in essential oil were obtained in compost + vermicompost treatment. It seems that compost + vermicompost treatment compared to other treatments supplied the highest equilibrium of nutrients and water in the root zone of sweet fennel which is led to increasing the anethole content, there upon, decreasing other compounds. Essential oil yield and percentage of anethole content in essential oil were significantly higher in all organic and biological treatments compared with control. (Author) 43 refs.

    Appetite controlling has been an main strategy for regulating food intake and energy balance in obesity treatment. The aim of this study was to examine the effects of drinking tea of the medicinal herbs, fennel and fenugreek, on the subjective appetite in overweight Korean women. The study was conducted using a placebo-controlled, single-blinded, randomized, and 3-way crossover design. Nine healthy women were given fennel tea (FT), fenugreek tea (FGT), or placebo tea (PT). After drinking a given tea, a lunch buffet was provided and then food consumption of subjects was analyzed. Subjective appetite, hunger, fullness, desire to eat, and prospective food consumption were measured at seven independent time point using a visual analog scale (VAS). Mean age of 9 subjects were 49.7 ± 4.5 years and their mean body mass index were 24.6 ± 0.6 kg/m(2). There was no significant difference in food consumption in the lunch buffet after drinking each tea; however, with respect to the subjective appetite scale, FGT decreased hunger, led to less prospective food consumption, and increased feelings of fullness compared with the PT (p < 0.05). Similarly, the consumption of FT resulted in decreased hunger, less prospective food consumption, and increased feelings of fullness compared with the PT (p < 0.05). The area under the curve of VAS graph indicated that FGT resulted in a higher feeling of fullness than the PT (p < 0.05). In conclusion, drinking the FT and FGT were significantly effective aid to suppress subjective appetite among overweight women in South Korea. PMID:26251835

    International Nuclear Information System (INIS)

    Anise seeds (Pimpenella anisum L.) were exposed to gamma irradiation doses (0, 4, 8, 16 and 32 KGy). Irradiated and un-irradiated anise seeds were stored for 3, 6 and 12 months and tested for their microbial population . In addition, the chemical constituents (volatile oils, fatty acids, lipids and sugars) were evaluated. The predominant microorganisms contaminated anise seeds include different fungal species identified as Aspergillus niger, A. ochraceus, A. parasiticus, A. flavus, A. fumigatus , Penicillium funiculosum , P. italicum , Rhizopus sp. and Trichoderma viride. Different bacterial species as Bacillus circulans, B. subtilis, B. megaterium, B. brevis, Pseudomonas fluorescens, P. oleourans and Alicyclobacillus acidocaldarius were recorded. The imposed irradiation doses showed a promising effect to decontaminate the microbial load , which in turn showed prolong the storage periods. Volatile oil content was relatively declined during storage. In addition, some alternations were happened regarding the essential oils constituents. However, the applied irradiation doses maintained the volatile oil content and retained its constituents near to the normal control. Total lipids content were not influenced by either the applied storage periods or the used gamma irradiation doses. However, the fatty acids methyl ester showed some changes due to the imposed treatments. Sugars content were increased in the stored and un-irradiated seeds, however, the exposure to gamma radiation reduced this increase and retained sugars content near to the normal level of the control seeds.

    Background The present study focused on a simple and eco-friendly method for the synthesis of silver nanoparticles (AgNPs) with multipurpose anticancer and antimicrobial activities. Materials and methods We studied a green synthesis route to produce AgNPs by using an aqueous extract of Pimpinella anisum seeds (3 mM). Their antimicrobial activity and cytotoxicity on human neonatal skin stromal cells (hSSCs) and colon cancer cells (HT115) were assessed. Results A biophysical characterization of the synthesized AgNPs was realized: the morphology of AgNPs was determined by transmission electron microscopy, energy dispersive spectroscopy, X-ray powder diffraction, and ultraviolet-vis absorption spectroscopy. Transmission electron microscopy showed spherical shapes of AgNPs of P. anisum seed extracts with a 3.2 nm minimum diameter and average diameter ranging from 3.2 to 16 nm. X-ray powder diffraction highlighted the crystalline nature of the nanoparticles, ultraviolet-vis absorption spectroscopy was used to monitor their synthesis, and Fourier transform infrared spectroscopy showed the main reducing groups from the seed extract. Energy dispersive spectroscopy was used to confirm the presence of elemental silver. We evaluated the antimicrobial potential of green-synthesized AgNPs against five infectious bacteria: Staphylococcus pyogenes (29213), Acinetobacter baumannii (4436), Klebsiella pneumoniae (G455), Salmonella typhi, and Pseudomonas aeruginosa. In addition, we focused on the toxicological effects of AgNPs against hSSC cells and HT115 cells by using in vitro proliferation tests and cell viability assays. Among the different tested concentrations of nanoparticles, doses 10 µg led to increased cytotoxicity. Conclusion Overall, our results highlighted the capacity of P. anisum-synthesized AgNPs as novel and cheap bioreducing agents for eco-friendly nanosynthetical routes. The data confirm the multipurpose potential of plant-borne reducing and stabilizing agents in

X-ray powder diffraction highlighted the crystalline nature of the nanoparticles, ultraviolet-vis absorption spectroscopy was used to monitor their synthesis, and Fourier transform infrared spectroscopy showed the main reducing groups from the seed extract. Energy dispersive spectroscopy was used to confirm the presence of elemental silver. We evaluated the antimicrobial potential of green-synthesized AgNPs against five infectious bacteria: Staphylococcus pyogenes (29213), Acinetobacter baumannii (4436), Klebsiella pneumoniae (G455), Salmonella typhi, and Pseudomonas aeruginosa. In addition, we focused on the toxicological effects of AgNPs against hSSC cells and HT115 cells by using in vitro proliferation tests and cell viability assays. Among the different tested concentrations of nanoparticles, doses 10 µg led to increased cytotoxicity. Conclusion Overall, our results highlighted the capacity of P. anisum-synthesized AgNPs as novel and cheap bioreducing agents for eco-friendly nanosynthetical routes. The data confirm the multipurpose potential of plant-borne reducing and stabilizing agents in

    In this study, antioxidant, antibacterial and antiglycation properties of methanolic extracts of 23 fennel samples were evaluated and their major compounds were determined using HPLC analysis. The anti-glycative activity of extracts was evaluated in the bovine serum albumin (BSA)/glucose system. The level of glycation, conformational alterations and protein binding to RAGE receptors were assessed by Congo red binding assay and a brown staining method. Among samples, Kh1 from Iran possessed the highest TFC (14.8mgQUEg(-1)), TPC (262mg/g DW) and antioxidant activity (IC50=76μg/ml). The HPLC results revealed high variation in 23 fennel samples according to their major flavonoid (quercetin, apigenin and rutin) and phenolic (chlorogenic, caffeic and 1,5-dicaffeoylquinic acid) compounds. The antibacterial activity of methanolic extracts against four food-borne pathogens was also assessed. The seed extracts of Kh1 and En samples showed moderate to good inhibitory activities (MICs=62.5-125μg/ml) against three bacteria, as well as high anti-glycative activity. PMID:27451172

    The ancestor of barley (Hordeum vulgare subsp. spontaneum) may be a source of novel alleles for crop improvement. We developed a set of recombinant chromosome substitution lines (RCSLs) using an accession of H. vulgare subsp. spontaneum (Caesarea 26-24, from Israel) as the donor and Hordeum vulgare subsp. vulgare 'Harrington' (the North American malting quality standard) as the recurrent parent via two backcrosses to the recurrent parent, followed by six generations of selfing. Here we report (i) the genomic architecture of the RCSLs, as inferred by simple sequence repeat (SSR) markers, and (ii) the effects of H. vulgare subsp. spontaneum genome segment introgressions in terms of three classes of phenotypes: inflorescence yield components, malting quality traits, and domestication traits. Significant differences among the RCSLs were detected for all phenotypes measured. The phenotypic effects of the introgressions were assessed using association analysis, and these were referenced to quantitative trait loci (QTL) reported in the literature. Hordeum vulgare subsp. spontaneum, despite its overall inferior phenotype, contributed some favorable alleles for agronomic and malting quality traits. In most cases, the introgression of the ancestral genome resulted in a loss of desirable phenotypes in the cultivated parent. Although disappointing from a plant breeding perspective, this finding may prove to be a useful tool for gene discovery.

    Stores products such a grains, flours, dry fruits and spices are normally infested by pests as beetles (Lasioderma serricorne), mites and moths, depreciating the product visually and promoting its deterioration. To improve the quality of spices, medicinal plants and others foodstuffs there is a need for adequate methods of handling, correct identification of the species, adequate collection and storage. The objective of this work was to determine the dose of gamma radiation for the disinfestation of medicinal and aromatic plants infested by L. serricorne. The plants used in this study were Chamomilla recutita L. and Pimpinela anisum L. in this dehydrated form. The experiment was carried out in the Laboratorio de Inseticidas e Acaricidas from Instituto Biologico/SP, during the months of January and May 2006, and the irradiations were carried out in the Instituto de Pesquisas Energeticas e Nucleares - IPEN/CNEN/SP, using and experimental Cobalt 60 irradiator, model Gammacell 220. Each treatment consisted of 5 parcels containing 10 g of dehydrated products infested with 20 last instar larvae of L. serricorne, conditioned in plastic 10 x 10 cm containers with small punctures in the cover to allow internal aeration. The substratum previously infested was submitted to increasing doses of gamma radiation: 0: 0.5; 0.75; 1.0; 1.25; 1.50; 1.75; 2.0; 2.25; 2.50 and 2.75 kGy. After irradiation, the samples were kept in a acclimatized room at 27 {+-} 2 deg C of temperature and relative humidity of 70 {+-} 5% and after a 45 days period the number of adults insects emerged was evaluated.

    Mosquitoes constitute a severe health problem in many areas all over the world. There are many regions of the tropics and subtropics where mosquitoes are one of the main reasons for inhibiting the economic upgrade. Except nuisance, their medical importance is another matter of attention since mosquitoes are vectors for a wide variety of vector-borne diseases. Due to disadvantages of currently used chemical control methods, it is unavoidable to search for eco-friendly new molecules. We report herein the evaluation of the larvicidal effect exhibited by essential oils of Dianthus caryophyllus, Lepidium sativum, Pimpinella anisum, and Illicium verum against late third to early fourth instar mosquito larvae of Culex pipiens. Furthermore, phytochemical analysis of plant samples revealed their major compounds to be β-caryophyllene, eugenol, eucalyptol, α-terpinyl acetate, and (E)-anethole which were also tested for their potential larvicidal activity. For D. caryophyllus and L. sativum, this was the first report on the chemical composition of their essential oils. The essential oils of I. verum and P. anisum demonstrated high larvicidal activity with a LC(50) <18 mg L(-1). The other two essential oils of D. caryophyllus and L. sativum revealed moderate larvicidal activity, displaying a LC(50) value above 50 mg L(-1). Among the pure components, the most toxic were eugenol, (E)-anethole, and α-terpinyl acetate, with LC(50) values 18.28, 16.56, and 23.03 mg L(-1), respectively. Eucalyptol (1,8 cineole) and β-caryophyllene were inactive at concentrations even as high as 100 mg L(-1), showing the least significant activity against mosquito larvae. Results allow some rationalization on the relative importance of the major compounds regarding the larvicidal activity of selected essential oils and their potential use as vector control agents.

    Full Text Available The epigraphic material from the region of Naissus, in spite of its relative scarcity and poor state of preservation, offers valuable examples of Vulgar Latin usage. Interesting phenomena include an instance of the imperial name Pertinax in the form Pertenax, which may be due to a vulgar reinterpretation of the name (‘Very Tough’, cf. Constans, Valens, sim. and may imply rhizotony (Perténax; the adjective superstantes ‘survivors’, apparently the issue of two consequent vulgar developments, superstes > superstens (hypercorrect spelling > superstans (false analogy; an isosyllabic 3rd declension nominative singular, Melioris (from the name Melior, as well as a 3rd decl. dative singular generi from the 2nd decl. noun gener ‘son-in-law’; an early borrowing from Germanic, brutes ‘daughter-in-law’; a ‘weak’ future participle, sequiture, for secuturae; the bastard noun volumptas, cf. voluntas and voluptas; a correlative construction with sic...sic for quemadmodum...sic; and the verb adjuvare followed by a dative, which illustrates a vulgarism known from the Glossaries. Another kind of vulgarity, which is rather a matter of simplicity than purely linguistic incompetence, is found in cases such as an epitaph whose dedicator calls herself bene merita; or a semi-metric inscription-a commaticum-whose actual text may be the outcome of tampering with a regular epigraphic poem

    Full Text Available Background: A number of studies on reproduction have mentioned Origanum Vulgare extract’s ability to reduce mortality rates and improve fertility rates. However, other studies have suggested that it is possible to use Origanum Vulgare extract to induce abortion. The aim of this study was to investigate the effect of different doses of Origanum Vulgare on embryo survival and macroscopic abnormalities in mice.Methods: In this study, 24 mice Balb/c female weighting approximately 25-30 g were divided into 4 groups. Origanum Vulgare extract was prepared; different concentrations (2.5, 12.5, and 25 mg in 0.25 ml distilled water were administered, by oral gavage, to three experimental groups of mice between day 6 (starting gastrulation until day 15 of pregnancy (end of organogenesis. The control group consisted of six mice that received 0.25 ml of distilled water daily. On day 16 of study, pregnant mice were anesthetized by chloroform and fetuses were removed and stained with Alcian Blue, Alizarin Red s and microwave irradiation. Morphological and skeletal abnormalities were investigated by light and stereomicroscopes.Results: The results of this study showed that high doses of the Origanum Vulgare extract significantly decreased the mean number of embryos (100.5, P>0.05, mean number of live embryos (70.5, P>0.05 in each mouse and resulted in significant reduction in mean weight(11848 mg, P>0.05 and crown-rump length(11.90.23 mm, P>0.05 and the overall size of fetuses compared to control group, whereas there was no significant difference between the groups receiving low dose of Origanum Vulgare extract with control group. In addition, under the effect of the Origanum Vulgare extract the subcutaneous bleeding seemed (20.1, P>0.05 significantly more frequent compared to the control group. Conclusion: Origanum Vulgare extract did not have any positive effect on fetal development; and high dosages led to an increased incidence rate of

    Full Text Available Natural products, known for their medicinal properties since antiquity, are continuously being studied for their biological properties. In the present study, we analyzed the composition of the volatile preparations of essential oils of the Greek plants Ocimum basilicum (sweet basil, Mentha spicata (spearmint, Pimpinella anisum (anise and Fortunella margarita (kumquat. GC/MS analyses revealed that the major components in the essential oil fractions, were carvone (85.4% in spearmint, methyl chavicol (74.9% in sweet basil, trans-anethole (88.1% in anise, and limonene (93.8% in kumquat. We further explored their biological potential by studying their antimicrobial, antioxidant and antiproliferative activities. Only the essential oils from spearmint and sweet basil demonstrated cytotoxicity against common foodborne bacteria, while all preparations were active against the fungi Saccharomyces cerevisiae and Aspergillus niger. Antioxidant evaluation by DPPH and ABTS radical scavenging activity assays revealed a variable degree of antioxidant potency. Finally, their antiproliferative potential was tested against a panel of human cancer cell lines and evaluated by using the sulforhodamine B (SRB assay. All essential oil preparations exhibited a variable degree of antiproliferative activity, depending on the cancer model used, with the most potent one being sweet basil against an in vitro model of human colon carcinoma.

    The essential oil of Clausena anisum-olens (Blanco) Merr. showed strong contact toxicity and repellency against Lasioderma serricorne and Liposcelis bostrychophila adults. The components of the essential oil obtained by hydrodistillation were determined by gas chromatography-mass spectrometry. It was found that the main components were myristicin (36.87%), terpinolene (13.26%), p-cymene-8-ol (12.38%), and 3-carene (3.88%). Myristicin and p-cymene-8-ol were separated by silica gel column chromatography, and their molecular structures were confirmed by means of physicochemical and spectrometric analysis. Myristicin and p-cymene-8-ol showed strong contact toxicity against L. serricorne (LD50 = 18.96 and 39.68 μg per adult) and Li. bostrychophila (LD50 = 20.41 and 35.66 μg per adult). The essential oil acting against the two grain storage insects showed LD50 values of 12.44 and 74.46 μg per adult, respectively. Myristicin and p-cymene-8-ol have strong repellent toxicity to Li. bostrychophila. PMID:26136499

    Aniseed (Pimpinella anisum L., Apiaceae) and its essential oil (EO) have been widely used. Because there are some data about the impact of aniseed EO on drug effects, this survey aimed to assess the potential of pharmacokinetic herb-drug interaction between aniseed EO and acetaminophen and caffeine in mice. The chemical analysis (gas chromatography-mass spectrometry) of aniseed EO has confirmed trans-anethole (87.96%) as the main component. The pharmacokinetic studies of intraperitoneally (i.p.) and orally applied acetaminophen (200 mg/kg) and caffeine (20 mg/kg) were performed in mice after 5 days of oral treatment with human equivalent dose of aniseed EO (0.3 mg/kg/day). The analysis of pharmacokinetic data showed that in the group treated by aniseed EO, the significant decrease in the peak plasma concentration of acetaminophen after oral application (p = 0.024) was revealed when compared with control group and the reduction of systemic exposure to the drug after oral application (74 ± 32% vs. 85 ± 35% in the control) was noted. The bioavailability of orally applied caffeine was also significantly decreased (p = 0.022) after the EO treatment in comparison with the control (57 ± 24% vs. 101 ± 29%). Therefore, the compromised therapeutic efficacy of acetaminophen and caffeine during the usage of aniseed EO preparations should be considered.

    In the present study, the antimicrobial and antiradical activities of 15 essential oils were investigated. The antimicrobial activities were determined by using agar disc diffusion and broth microdilution methods against Clostridium genus and antioxidant properties of essential oils by testing their scavenging effect on DPPH radicals activities. We determined the antibacterial activity of Clostridium butyricum, Clostridium hystoliticum, Clostridium intestinale, Clostridium perfringens and Clostridium ramosum. We obtained the original commercial essential oils samples of Lavandula angustifolia, Carum carvi, Pinus montana, Mentha piperita, Foeniculum vulgare Mill., Pinus sylvestris, Satureia montana, Origanum vulgare L. (2 samples), Pimpinella anisum, Rosmarinus officinalis L., Salvia officinalis L., Abies alba Mill., Chamomilla recutita L. Rausch and Thymus vulgaris L. produced in Slovakia (Calendula a.s., Nova Lubovna, Slovakia). The results of the disk diffusion method showed very high essential oils activity against all tested strains of microorganisms. The best antimicrobial activity against C. butyricum was found at Pimpinella anisum, against C. hystoliticum was found at Pinus sylvestris, against C. intestinale was found at Satureia hortensis L., against C. perfringens was found at Origanum vulgare L. and against C. ramosum was found at Pinus sylvestris. The results of broth microdilution assay showed that none of the essential oils was active against C. hystoliticum. The best antimicrobial activity against C. butyricum was found at Abies alba Mill., against C. intestinale was found at Abies alba Mill., against C. perfringens was found at Satureia montana and against C. ramosum was found at Abius alba and Carum carvi. Antioxidant DPPH radical scavenging activity was determined at several solutions of oil samples (50 μL.mL(-1)-0.39 μL.mL(-1)) and the best scavenging effect for the highest concentration (50 μL.mL(-1)) was observed.

    The isolation and identification of major phenylpropanoid esters from Marrubium vulgare: (+) (E)-caffeoyl-L-malic acid 1, acteoside 2, forsythoside B 3, arenarioside 4, ballotetroside 5, as well as their anti-inflammatory activity are reported for the first time. We evaluated the inhibitory effects of these five compounds on cyclooxygenase (Cox) catalysed prostaglandin biosynthesis activity. Only the glycosidic phenylpropanoid esters showed an inhibitory activity towards the Cox-2 enzyme and three of them: acteoside 2, forsythoside B 3, arenarioside 4, exhibited higher inhibitory potencies on Cox-2 than on Cox-1. These results are of interest, as Cox-2 is mainly associated with inflammation and the Cox-1 inhibition with adverse side effects often observed with non-steroidal anti-inflammatory drugs. The occurrence of these phenylpropanoid esters could also explain some other pharmacological properties of M. vulgare. PMID:11849848

    Full Text Available Due to anthelmintic resistance in nematodes, several research studies have been developed seeking control alternatives to these parasites. This study evaluated the in vitro action of Origanum vulgare on gastrointestinal nematode eggs of cattle. In order to evaluate the ability to inhibit egg hatch, different dried leaves extracts of this plant were tested, such as dye, hydroalcoholic and aqueous extracts at concentrations varying from 0.62 to 80 mg/mL. Each assay was accompanied by control containing levamisole hydrochloride (0.2 mg/mL, distilled water and 70 ºGL grain alcohol at the same concentration of the extracts. Test results showed that the different O. vulgare extracts inhibited egg hatch of cattle gastrointestinal nematodes at a percentage that varied from 8.8 to 100%; dye and hydroalcoholic extract were the most promising inhibitors. In view of this ovicidal property, O. vulgare may be an important source of viable antiparasitic compounds for nematodiosis control in ruminants.

    This investigation focused on the qualitative and quantitative composition of essential oil compounds of European Origanum vulgare. Extracts of 502 individual O. vulgare plants from 17 countries and 51 populations were analyzed via GC. Extracts of 49 plants of 5 populations of Israeli Origanum syriacum and 30 plants from 3 populations of Turkish Origanum onites were included to exemplify essential oil characteristics of 'high-quality' oregano. The content of essential oil compounds of European O. vulgare ranged between 0.03% and 4.6%. The monoterpenes were primarily made up of sabinene, myrcene, p-cymene, 1,8-cineole, β-ocimene, γ-terpinene, sabinene hydrate, linalool, α-terpineol, carvacrol methyl ether, linalyl acetate, thymol and carvacrol. Among the sesquiterpenes β-caryophyllene, germacrene D, germacrene D-4-ol, spathulenol, caryophyllene oxide and oplopanone were often present in higher amounts. According to the proportions of cymyl-compounds, sabinyl-compounds and the acyclic linalool/linalyl acetate three different main monoterpene chemotypes were defined. The cymyl- and the acyclic pathway were usually active in plants from the Mediterranean climate whereas an active sabinyl-pathway was a characteristic of plants from the Continental climate.

    2015-12-01

    Full Text Available In this article we study the translations of Carlos Jansen for the youth, age group corresponding approximately to the contemporary concepts of preadolescence and adolescence, made at the end of the 19th century. Jansen was a pioneer in translating into Brazilian Portuguese works for the youth among which novels by Swift, Defoe, and Cervantes. His widely adapted versions had a pedagogical goal, serving as a reading material for children and adolescents attending schools. For this reason he was called a "vulgarizer" by critics of that period. The research encompassed the analysis of newspapers published between 1880 and 1899, available at the National Library's Hemeroteca Digital Brasileira, which provide data on the advertising and reception of his works. We intend to enrich historical research on children's literature in Brazil and analyse to what degree Jansen's pedagogical project has governed his translation practice.

  19. Monosomic and double monosomic substitutions of Hordeum bulbosum L. chromosomes into H. vulgare L.

    Pickering, R A

    1992-07-01

    One of the aims of the interspecific crossing programme between Hordeum vulgare L. and H. bulbosum L. has been to introgress desirable genes into barley from the wild species. However, despite their close taxonomic relationship there have been few reports of achieving this objective using amphidiploid hybrids. In order to broaden the range of available hybrids, partially fertile triploids between H. vulgare (2n = 2x = 14) and H. bulbosum (2n = 4x = 28) were developed and crossed with H. vulgare as female parent. From 580 progeny which were screened, eight putative single monosomic chromosome substitution lines and one double monosomic substitution were identified by cytological analysis. These involved the substitution of H. vulgare chromosome 1 (two lines), 6 (four lines), 6L (one line), 7 (one line) and 1 + 4 (one line) by their respective H. bulbosum homoeologues. The H. bulbosum chromosome was frequently eliminated during plant development, but it was observed regularly in pollen mother cells of two lines. However, pairing between the H. bulbosum chromosome and its H. vulgare homoeologue was low. Several of the lines were more resistant than their H. vulgare parents to powdery mildew (Erysiphe graminis DC. f.sp. hordei Em. Marchai), net blotch (Drechslera teres Sacc.) and scald (Rhynchosporium secalis (Oudem.) Davis). Apart from their use in studying genome relationships, their value to plant breeders will depend on the ease of inducing translocations between the parental chromosomes.

  20. Proteomic analysis of Ketogulonicigenium vulgare under glutathione reveals high demand for thiamin transport and antioxidant protection.

    Directory of Open Access Journals (Sweden)

    Qian Ma

    Full Text Available Ketogulonicigenium vulgare, though grows poorly when mono-cultured, has been widely used in the industrial production of the precursor of vitamin C with the coculture of Bacillus megaterium. Various efforts have been made to clarify the synergic pattern of this artificial microbial community and to improve the growth and production ability of K. vulgare, but there is still no sound explanation. In previous research, we found that the addition of reduced glutathione into K. vulgare monoculture could significantly improve its growth and productivity. By performing SEM and TEM, we observed that after adding GSH into K. vulgare monoculture, cells became about 4-6 folds elongated, and formed intracytoplasmic membranes (ICM. To explore the molecular mechanism and provide insights into the investigation of the synergic pattern of the co-culture system, we conducted a comparative iTRAQ-2-D-LC-MS/MS-based proteomic analysis of K. vulgare grown under reduced glutathione. Principal component analysis of proteomic data showed that after the addition of glutathione, proteins for thiamin/thiamin pyrophosphate (TPP transport, glutathione transport and the maintenance of membrane integrity, together with several membrane-bound dehydrogenases had significant up-regulation. Besides, several proteins participating in the pentose phosphate pathway and tricarboxylic acid cycle were also up-regulated. Additionally, proteins combating intracellular reactive oxygen species were also up-regulated, which similarly occurred in K. vulgare when the co-cultured B. megaterium cells lysed from our former research results. This study reveals the demand for transmembrane transport of substrates, especially thiamin, and the demand for antioxidant protection of K. vulgare.

A total of 65 compounds with different antioxidant capacity, phenolic substance content and antibacterial properties were detected with 14 plant essential oils. The best-fit M(N)LR models indicated that relative to anise essential oil, the essential oils of oreganos, cinnamon, and thyme had consistently high inhibitory effects, while orange peel essential oil had consistently a low inhibitory effect. Regression analysis indicated that beta-bisabolene (Turkish and Istanbul oreganos), and terpinolene (thyme) were found to be the most inhibitory compounds regardless of the bacteria type tested.

    Evidence is presented that chlorate is an extremely good analog for nitrate during nitrate uptake by intact barley (Hordeum vulgare cv. Fergus) roots. The depletion of ClO3− or NO3− from uptake media over 2 to 6 hours by seedlings was found to be dependent on combined NO3− plus ClO3− concentrations, and total anion uptake was equivalent at different NO3−/ClO3− ratios. After loading barley seedlings with 36ClO3− for 6 hours, kinetic parameters were derived from the analysis of efflux of [36Cl] chlorate into unlabeled solution. On the basis of this analysis, the half times for exchange for the cytoplasmic and vacuolar phases were 17 minutes and 20 hours, respectively. Data pooled from a number of different experiments were used to calculate kinetic constants (Km and Vmax) for 36ClO3− influx into barley roots at different external ClO3−/NO3− ratios, using short (10 minutes) influx times. There appeared to be no discrimination by the root cells between ClO3− and NO3−. Lineweaver-Burk analysis of the interaction between nitrate and chlorate were characteristic of competitive inhibition at low nitrate concentrations (0-0.5 mm). At higher concentrations, in the range of >1 mm, similar interactions between these ions were evident. PMID:16662478

    Full Text Available Total lipids from the Brazilian brown seaweed Sargassum vulgare were extracted with chloroform/methanol 2:1 and 1:2 (v/v at room temperature. After performing Folch partition of the crude lipid extract, the lipids recovered from the Folch lower layer were fractionated on a silica gel column eluted with chloroform, acetone and methanol. The fraction eluted with methanol, presented a strong orcinol-positive band characteristic of the presence of sulfatides when examined by TLC. This fraction was then purified by two successive silica gel column chromatography giving rise to fractions F4I86 and F4II90 that exhibited strong activity against herpes simplex virus type 1 and 2. The chemical structures present in both fractions were elucidated by ESI-MS and 1H/13C NMR analysis HSQC fingerprints based on their tandem–MS behavior as Sulfoquinovosyldiacylglycerols  (SQDGs. The main SQDG present in both fractions and responsible for the anti-herpes activity observed was identified as 1,2-di-O-palmitoyl-3-O-(6-sulfo-α-d-quinovopyranosyl-glycerol.

    This paper describes the antioedematogenic profile of marrubiin (1), the main constituent of Marrubium vulgare, a medicinal plant used in folk medicine of several countries to treat different pathologies. Compound (1) was analyzed in a model of microvascular leakage in mice ears. The results show that it exhibits significant and dose-related antioedematogenic effects. The results obtained for ID50 values (mg/kg, i.p.) and maximal inhibition (%) for the different phlogistic agents used were as follows: histamine (HIS, 13.84 mg/kg and 73.7%); (BK, 18.82 mg/kg and 70.0%); carrageenan (CAR, 13.61 mg/kg and 63.0%). The other phlogistic agonists, such as prostaglandin E2 (PGE2), caused inhibition of less than 50%. In addition, (1) (100 mg/kg) significantly inhibited the OVO-induced allergic edema in actively sensitized animals (maximal inhibition 67.6+/-4%). Our results demonstrate that the systemic administration of marrubiin exerts a non-specific inhibitory effect on pro-inflammatory agent-induced microvascular extravasation of Evans blue in mouse ear.

    Full Text Available The aim of the present work was to determine the in vitro effect of T. vulgaris and O. vulgare essential oils against E. granulosus protoscoleces and cysts. Essential oils were added to the medium resulting in thymol final concentrations of 10 μg/mL. The essential oils had a time-dependent effect provoking the complete loss of protoscolex viability after 72 days of postincubation. The results were confirmed at the ultrastructure level. Loss of infectivity in protoscoleces incubated with O. vulgare after 60 days was observed. On the other hand, the weight of cysts recorded in mice inoculated with T. vulgaris treated protoscoleces was significantly lower than that obtained in control group. Gamma-glutamyl-transpeptidase activity was readily detected in the culture supernatant of protoscoleces treated either with the essential oils or thymol. T. vulgaris and O. vulgare essential oils and thymol can induce cell apoptosis of protoscoleces after short incubation times. The efficacy of T. vulgaris and O. vulgare essential oils was also demonstrated in vitro on E. granulosus murine cysts. Our data suggest that essential oils of T. vulgaris and O. vulgare have anthelmintic effect against protoscoleces and cysts of E. granulosus.

    The hepatoprotective activity of Marrubium vulgare against cyclophosphamide toxicity in Wistar rats was evaluated. Adult male rats were divided into 4 groups of 6 each: a control group, a group injected with cyclophosphamide (150 mg·kg(-1)) for 3 days, a group orally given a M. vulgare aqueous extract ((500 mg of dry leaves)·kg(-1)·day(-1)) for 30 days then treated with cyclophosphamide, and a group receiving only M. vulgare for 30 days. After 33 days of treatment, activities of alanine amino transferase (ALAT), aspartate amino transferase (ASAT), lactate dehydrogenase (LDH), and alkaline phosphatase (ALP) were determined in serum. Moreover, lipid peroxidation level and superoxide dismutase (SOD) activities, catalase (CAT) and glutathione peroxidase (GPx) were measured in liver. Alterations of these hepatic biomarkers and increased lipid peroxidation confirmed cyclophosphamide-induced liver toxicity. Cyclophosphamide also decreased the enzymatic defense system against oxidative stress. However, when this drug was administered in rats given M. vulgare extract, all the biological parameters underwent much less alteration. Administration of M. vulgare extract was found to be beneficial by attenuating cyclophosphamide-induced liver damage. The protective effect of the plant is mainly attributed to its antioxidant properties and the existence of phenolic acids and flavonoids, as highlighted by HPLC-based analysis. PMID:26886858

    Full Text Available Pimpinella anisum, is a plant species popularly used as treatment for different diseases, although no studies exist which could prove its pharmacological activity. This species has no known methods of asepsis and adequate conditions to conduct in vitro propagation trials. To assess the most efficient method of seed sterilization and the most favorable concentration of agar and MS salts, five tests of asepsis and tests to evaluate the dry mass increase of germinated seed in 3g/L and 6g/L of agar and MS in concentrations of 0%, 25%, 50%, 75% and 100%, were carried out. The samples that were immersed in a concentration of 2% sodium hypochlorite for 20 minutes and then washed in distilled water produced 100% of sterile plantlets. The greatest increase in dry mass was obtained with 75% and 100% of MS salts. Furthermore, the different concentrations of agar did not influence the percentage of the plantlets dry mass. Pimpinella anisum é uma planta popularmente utilizada como medicinal para diversas enfermidades, embora não existam estudos que comprovem sua atividade farmacológica. A espécie não apresenta metodologias conhecidas de assepsia e condições adequadas para experimentos de propagação in vitro. Para avaliar a forma mais eficiente de esterilização de sementes da espécie e melhores concentrações de ágar e sais do meio MS, foram feitos cinco testes de assepsia, bem como testes de avaliação do aumento de massa seca a partir de sementes germinadas em ágar 3g/L e 6g/L e MS nas concentrações 0%, 25%, 50%, 75% e 100%. A imersão em solução hipoclorito de sódio 2% por 20 minutos e lavagem em água destilada promoveu 100% de plântulas estéreis. O maior aumento de massa seca foi obtido com concentração de sais do meio MS de 75% e 100%, e as diferentes concentrações de ágar não influenciaram a obtenção de maior percentual de massa de plântulas cultivadas.

    Four B-hordein genes, designated BH1-BH4, were cloned using PCR amplification from two hull-less barley cultivars, ZQ7239 and ZQ148, collected from Tibet. The results of sequencing indicated that BH1-BH4 contained complete open reading frames (ORFs). Comparison of their predicted polypeptide sequences with the published sequences suggested that they all share the same basic protein structure. Phylogenetic analysis indicated that the deduced amino-acid sequences of BH1-BH4 genes were more closely related to B-hordeins from cultivated barley (Hordeum vulgare L.) than to any other prolamins from wild barley and Aegilops tauschii. Comparison of the coding regions of BH1-BH4 genes showed that BH1 had a lower sequence identity to other previously published B-hordeins than the other three B-hordeins obtained in this study. BH1 was then cloned in a bacterial expression vector based on bacteriophage T7 RNA polymerase. The resulting plasmid produced a 28.15 kDa protein in Escherichia coli. The potential value of B-hordein genes in grain quality improvement of hull-less barley has been discussed. PMID:17046594

    The recommended conservative treatment of hyperoxaluria is mainly based on hyperhydration and ingestion of inhibitors of crystallization. In accordance with this context, the aim of this study was to determine the in vitro effect of Hordeum vulgare on calcium oxalate crystallization oxalo-dependent. The crystallization of calcium oxalate monohydrate in supersaturated aqueous solution at 37 °C, was followed in a model turbidimetric continuous in a closed system. The proposed model is very good reproducibility (CV < 10%), crystallization was monitored continuously in the presence of Hordeum vulgare at different concentrations (0.0625 to 1 g/L). The comparison of turbidimetric parameters, that characterize the growth stage of monohydrated oxalate calcium crystals and observation of the crystals obtained at the end of crystallization into scanning electron microscopy, have been able to demonstrate the inducing effect of Hordeum vulgare to 0.0625 g/L and a slight inhibitory effect at the others concentrations.

    Full Text Available This paper investigates the antimicrobial action of the extracts and essential oil of wildgrowing Tanacetum vulgare L on: Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Bacilus subtilis, using the diffusion disc method. The essential oils but also the ethanolic extracts tested exhibited moderate action on Staphilococcus aureus and Bacillus subtilis and low action on E. coli and Pseudomonas aeruginosa. The moderate antimicrobial activity is related to the amount of some chemical components of the essential oil of T. vulgare flos. Thus, this paper presents also the quantitative and qualitative analysis of the essential oils of T. vulgare harvested from two different habitats. The essential oils obtained by steam-distillation were analysed by gas-cromatography coupled with mass spectrometry (GC-MS.

    Full Text Available The micromorphology of selected elements of Echium vulgare L. flowers was investigated, with special attention to the structure of the nectaries and the stigma of the pistil as well as types of trichomes occurring on the surface of the calyx. The nectary had the shape of an uneven disc located around the lower region of the four-parted ovary of the pistil. The glandular cells formed a tier with a height of 330 μm and a radial width of 144 μm. Nectar was secreted onto the nectary surface through anomocytic stomata located at the level of other epidermal cells. Most of the stomata were open, with a different dimension of the pore. Their largest number was observed at the base of the nectary, and 462 stomata were noted on the whole surface of the nectary. The cuticle on the surface of the guard cells formed fine, circular striae. The subsidiary cells formed striated cuticular ornamentation, with the striae arranged radially in the direction of the stoma, whereas on the surface of other epidermal cells the striae formed an arrangement with different directions. The epidermis on the surface of the stigma formed regularly arranged papillae with a fan-shaped, expanded upper part which had corrugated outer walls, whereas the base of the cell formed a widened small column. The epidermis of the abaxial part of the calyx was covered by numerous non-glandular trichomes of different length which were made up of one or several cells. The glandular trichomes in the epidermis of the calyx grew with smaller density compared to the protective trichomes, and they were composed of a 1-2-celled stalk and a glandular head.

    Full Text Available Origanum vulgare L., Lamiaceae, from six different production areas of China and Pakistan were analyzed via gas chromatography equipped with a flame ionization detector (GC-FID and examined for their volatile constituents by gas chromatography-mass spectroscopy (GCMS. This procedure allowed the identification of 11 to 46 components among six production areas, representing 98.5% to 99.9% of the total oil extracted. The yields of the essential oil of the six production areas of O. vulgare ranged from 0.1 to 0.7%. The class of oxygenated monoterpenes was predominant in all the essential oils. However, samples S5 and S6 have high content of sesquiterpene hydrocarbons (33.7 and 43.7%; while sample S6 is high on oxygenated sesquiterpene (32.9%. The principal component analysis of O. vulgare was employed to provide a comprehensive evaluation of essential oil components. The cluster analysis of O. vulgare was classified into three subsets, characterized according to the major essential oil components. The current study investigated the composition differences of essential oil among six production areas offering foundation for quality control, resource optimization, and clinical treatments.

    Affected by the vulgar culture outside the campus, the school culture is degenerating into a low taste. Rather than aiming at just values and objectives, providing cultural products of fine taste and with historical significance, and cultivating noble and moral life views, the current school culture pays too much attention to its utility and form, leading to an epidemic of vulgarism in the cultural life on campus. The campaign against vulgarism on campus is to build a culture of fine taste and construct a new normal for school culture, thus leading it back to its original function of ideological enlighten-ment as well as value guidance and education.%受社会庸俗文化的影响,学校文化庸俗现象愈加严重。学校文化价值“功利化”,重工具轻价值,缺乏正确的目的感;学校文化内容“低俗化”,重低级轻品位,缺乏高雅的境界感;学校文化过程“形式化”,重形式轻本质,缺乏深沉的历史感;学校文化结果“媚俗化”,重鄙俗轻高尚,缺乏崇高的道德感。反庸俗的学校文化就是要构建高雅文化,提升学校文化品位,形塑学校文化新常态,使学校文化回归到思想启蒙、价值引领与教育引导等本真意涵上来。

    Barley (Hordeum vulgare) is an economically important species, which can be cultivated in environmentally adverse conditions due to its higher tolerance in contrast to other cereal crops. The draft of H. vulgare genome is available already for couple of years; however its functional annotation is still incomplete. All available databases were searched to expand current annotation. The improved annotation was used to describe processes and genes regulated in transgenic lines showing higher tolerance to drought in our associated article, doi:10.1016/j.nbt.2016.01.010 (Vojta et al., 2016) [1]. Here we present whole transcriptome response, using extended annotation, to severe drought stress and subsequent re-watering in wild-type barley plants in stem elongation phase of growth. Up- and down-regulated genes fall into distinct GO categories and these enriched by stress and revitalization are highlighted. Transcriptomic data were evaluated separately for root and aerial tissues. PMID:27331111

    A sensitive method to examine the brassinolide (BL) response of barley (Hordeum vulgare L.) using dark-grown leaf segments was established based on the known method for wheat. BL responses of 53 dwarf isogenic lines of barley were examined, and two lines were found having a uzu gene that doesn't respond significantly. These results indicate that uzu dwarfism may be caused by the non-responding character to BL.

    Informed collecting, conservation, monitoring and utilization of genetic diversity requires knowledge of the distribution and structure of the variation occurring in a species. Hordeum vulgare subsp. spontaneum (K. Koch) Thell., a primary wild relative of barley, is an important source of genetic diversity for barley improvement and co-occurs with the domesticate within the center of origin. We studied the current distribution of genetic diversity and population structure in H. vulgare subsp. spontaneum in Jordan and investigated whether it is correlated with either spatial or climatic variation inferred from publically available climate layers commonly used in conservation and ecogeographical studies. The genetic structure of 32 populations collected in 2012 was analyzed with 37 SSRs. Three distinct genetic clusters were identified. Populations were characterized by admixture and high allelic richness, and genetic diversity was concentrated in the northern part of the study area. Genetic structure, spatial location and climate were not correlated. This may point out a limitation in using large scale climatic data layers to predict genetic diversity, especially as it is applied to regional genetic resources collections in H. vulgare subsp. spontaneum.

    1997-09-01

    The biosynthesis of the furanic labdane diterpene marrubiin has been studied in plantlets and shoot cultures of Marrubium vulgare (Lamiaceae). The use of [2-14C]acetate, [2-14C]pyruvate, [2-14C]mevalonic acid and [U-14C]glucose incorporation experiments showed that the labelling of sterols in etiolated shoot cultures of M. vulgare was in accordance with their biosynthesis via the acetate-mevalonate pathway. In contrast, the incorporation rates of these precursors into the diterpene marrubiin could not be explained by biosynthesis of this compound via the acetate-mevalonate pathway. Cultivation of etiolated shoot cultures of M. vulgare on medium containing [1-13C]glucose and subsequent 13C-NMR spectroscopy of marrubiin led to the conclusion that the biosynthesis of marrubiin follows a non-mevalonate pathway. All isoprenic units of 13C-labelled marrubiin were enriched in those carbons that correspond to positions 1 and 5 of a putative precursor isopentenyl diphosphate. This labelling pattern from [1-13C]glucose is consistent with an alternative pathway via trioses, which has already been shown to occur in Eubacteria and Gymnospermae. The labdane skeleton is a precursor of many other skeletal types of diterpenes. Therefore it becomes obvious that in connection with the few known examples of a non-mevalonate pathway to isoprenoids the formation of some isoprenoids in plants via a non-mevalonate pathway might be quite common.

  5. Using elevated CO2 to increase the biomass of a Sorghum vulgare x Sorghum vulgare var. sudanense hybrid and Trifolium pratense L. and to trigger hyperaccumulation of cesium

    International Nuclear Information System (INIS)

    The most important challenge to use phytoremediation is how to improve its efficiency by increasing the accumulation of metals in plants, or by improving key plant biological traits that should enhance metal uptake. In this paper, we used open-top chambers to investigate the effects of elevated CO2 (860 μL L-1) on biomass and Cs uptake by a Sorghum vulgare x Sorghum vulgare var. sudanense hybrid and Trifolium pratense L. growing on soils spiked with various levels of cesium (0, 300, 1500 and 3000 mg Cs kg-1). The results showed that elevated CO2 not only increased aboveground biomass of the Sorghum and Trifolium species by 32-111%, and by 8-11%, respectively, compared to the ambient CO2 treatment, but also caused more accumulation of Cs by Sorghum species (up to 73%) than Trifolium species (up to 43%). It was speculated that the increase in biomass and the improvement in Cs accumulation ability at elevated CO2 could be related to lowered soil pH values, and changes in number and kind of microorganisms in the rhizospheres of the two tested species. This is the first report of a link among elevated CO2, increased biomass and hyperaccumulation of Cs by Sorghum and Trifolium species.

    Essential oils possess strong antimicrobial activity, even against multiresistant Helicobacter pylori. Available therapies against H. pylori infection have multiple disadvantages, indicating a great need for a development of new therapeutics. The purpose of this study was to develop a potent natural product based anti-H. pylori formulation. First, anti-H. pylori activity of nine essential oils was determined, after which the most active oils were mixed in various ratios for further testing. Satureja hortensis, Origanum vulgare subsp. vulgare and O. vulgare subsp. hirtum essential oils expressed the highest activity (MIC = 2 μL mL(-1)). Their binary and ternary mixtures exhibited notably higher antimicrobial activity (MIC ≤ 2 μL mL(-1)). The most active was the mixture of S. hortensis and O. vulgare subsp. hirtum oils in volume ratio 2:1, which expressed 4 times higher activity than individual oils (MIC = 0.5 μL mL(-1)). According to GC-MS, both oils in the mixture were characterized by high content of phenols (48-73%), with carvacrol as the main carrier of antimicrobial activity. Presented in vitro study pointed out binary mixture of S. hortensis and O. vulgare subsp. hirtum essential oils in volume ratio 2:1 as promising candidate for further in vivo studies targeting H. pylori infection.

    Antilisterial activities of Thymbra capitata and Origanum vulgare essential oils were tested against 41 strains of Listeria monocytogenes. The oil of T. capitata was mainly constituted by one component, carvacrol (79%), whereas for O. vulgare three components constituted 70% of the oil, namely, thymol (33%), gamma-terpinene (26%), and p-cymene (11%). T. capitata essential oil had a significantly higher antilisterial activity in comparison to O. vulgare oil and chloramphenicol. No significant differences in L. monocytogenes susceptibilities to the essential oils tested were registered. The minimum inhibitory concentration values of T. capitata essential oil and of carvacrol were quite similar, ranging between 0.05 and 0.2 microL/mL. Antioxidant activity was also tested, the essential oil of T. capitata showing significantly higher antioxidant activity than that of O. vulgare. Use of T. capitata and O. vulgare essential oils can constitute a powerful tool in the control of L. monocytogenes in food and other industries. PMID:16218659

    Plants living in different ecological habitats can show significant variability in their histological and phytochemical characters. The main histological features of various populations of three medicinal plants from the Boraginaceae family were studied. Stems, petioles and leaves were investigated by light microscopy in vertical and transverse sections. The outline of the epidermal cells, as well as the shape and cell number of trichomes was studied in leaf surface casts. Differences were measured among the populations of Echium vulgare in the width and height of epidermis cells in the stem, petiole and leaf, as well as in the size of palisade cells in the leaves. Among the populations of Pulmonaria officinalis significant differences were found in the length of trichomes and in the slightly or strongly wavy outline of epidermal radial cell walls. Populations of Symphytum officinale showed variance in the height of epidermal cells in leaves and stems, length of palisade cells and number of intercellular spaces in leaves, and the size of the central cavity in the stem. Boraginaceae bristles were found to be longer in plants in windy/shady habitats as opposed to sunny habitats, both in the leaves and stems ofP. officinalis and S. officinale, which might be connected to varying levels of exposure to wind. Longer epidermal cells were detected in the leaves and stems of both E. vulgare and S. officinale plants living in shady habitats, compared with shorter cells in sunny habitats. Leaf mesophyll cells were shorter in shady habitats as opposed to longer cells in sunny habitats, both in E. vulgare and S. officinale. This combination of histological characters may contribute to the plant's adaptation to various amounts of sunshine. The reported data prove the polymorphism of the studied taxa, as well as their ability to adapt to various ecological circumstances.

    Marrubium vulgare (Lamiaceae) is a medicinal plant whose major bioactive compounds, marrubiin and other labdane-related furanoid diterpenoids, have potential applications as anti-diabetics, analgesics or vasorelaxants. Metabolite and transcriptome profiling of M. vulgare leaves identified five different candidate diterpene synthases (diTPSs) of the TPS-c and TPS-e/f clades. We describe the in vitro and in vivo functional characterization of the M. vulgare diTPS family. In addition to MvEKS ent-kaurene synthase of general metabolism, we identified three diTPSs of specialized metabolism: MvCPS3 (+)-copalyl diphosphate synthase, and the functional diTPS pair MvCPS1 and MvELS. In a sequential reaction, MvCPS1 and MvELS produce a unique oxygenated diterpene scaffold 9,13-epoxy-labd-14-ene en route to marrubiin and an array of related compounds. In contrast with previously known diTPSs that introduce a hydroxyl group at carbon C-8 of the labdane backbone, the MvCPS1-catalyzed reaction proceeds via oxygenation of an intermediate carbocation at C-9, yielding the bicyclic peregrinol diphosphate. MvELS belongs to a subgroup of the diTPS TPS-e/f clade with unusual βα-domain architecture. MvELS is active in vitro and in vivo with three different prenyl diphosphate substrates forming the marrubiin precursor 9,13-epoxy-labd-14-ene, as identified by nuclear magnetic resonance (NMR) analysis, manoyl oxide and miltiradiene. MvELS fills a central position in the biosynthetic system that forms the foundation for the diverse repertoire of Marrubium diterpenoids. Co-expression of MvCPS1 and MvELS in engineered E. coli and Nicotiana benthamiana offers opportunities for producing precursors for an array of biologically active diterpenoids.

    Full Text Available Marrubium vulgare L., commonly known as a white horehound or common horehound, belongs to the plant family Lamiaceae. It is a perennial aromatic herb which grows naturally in Europe, Asia, and America. Since ancient Egypt, this species has been known as a remedy for upper respiratory tract ailments. Nowadays, horehound is used in herbal medicine for treatment of liver diseases, biliary tract disorders, and for increasing the appetite and supporting the function of the stomach. The main biologically active substances in M. vulgare organs are: marrubiin, tannins, essential oils, and ursolic acid. The paper presents micromorphological analyses of non-glandular and glandular trichomes of M. vulgare. The research material was sampled from the plant collection in the Botanical Garden of the Maria Curie-Sklodowska University in Lublin (51°14′ N, 22°34′ E. The above-ground parts of horehound were collected during the flowering period in July 2013. Using light microscopy (LM and scanning electron microscopy (SEM, the types and sizes of trichomes from the stem, leaf, calyx, and corolla were investigated. The results of the microscopic observations show that the surfaces of M. vulgare vegetative and reproductive organs are densely clothed with glandular and non-glandular trichomes. The glandular trichomes are of two main types: peltate and capitate. Peltate trichomes consist of a short stalk cell and a large head with secretory cells arranged in a circle. The height of a mature trichome is about 31.33 μm and the diameter of the head is 31.47 μm. The substance produced by secretory cells passes through the apical walls and accumulates within a space between the cuticle and the cell wall layer. Capitate long trichomes with a basal cell, long stalk, neck cell, and a unicellular head are 36.65 μm long and the diameter of the head is about 15.6 μm. There are two types of short capitate trichomes: with a bicellular head and a unicellular stalk and with

    Pyrrolizidine alkaloids (PAs) in honey can be a potential human health risk. So far, it has remained unclear whether PAs in honey originate from pollen or floral nectar. We obtained honey, nectar, and plant pollen from two observation sites where Echium vulgare L. was naturally abundant. The PA concentration of honey was determined by targeted analysis using a high pressure liquid chromatography-mass spectrometry system (HPLC-MS/MS), allowing the quantification of six different PAs and PA-N-oxides present in E. vulgare. Echium-type PAs were detected up to 0.153 μg/g in honey. Nectar and plant pollen were analyzed by nontargeted analysis using ultrahigh pressure liquid chromatography-high resolution-mass spectrometry (UHPLC-HR-MS), allowing the detection of 10 alkaloids in small size samples. Echium-type PAs were detected between 0.3-95.1 μg/g in nectar and 500-35000 μg/g in plant pollen. The PA composition in nectar and plant pollen was compared to the composition in honey. Echimidine (+N-oxide) was the main alkaloid detected in honey and nectar samples, while echivulgarine (+N-oxide) was the main PA found in plant pollen. These results suggest that nectar contributes more significantly to PA contamination in honey than plant pollen. PMID:27244472

    Full Text Available Zoologists distinguish individual animals using marking techniques. Generally they test the potential influence of marking on survival only; the influence on behaviour is usually neglected. We evaluated the influence of two external marking techniques (nail polish and queen-bee marker on the behaviour of common pill woodlouse, Armadillidium vulgare. The behaviour was examined from two points of view: (1 activity during 24 hours and (2 specific expressions of behaviour (exploring, feeding, resting and hiding over a 24 hour period. We compared behaviour among woodlice marked with nail polish and queen-bee marker with the unmarked control group during a nine-day experiment. Although we did not find any influence of marking on survival, there was an evident influence on behaviour in most cases. Generally, in the groups of marked individuals of A. vulgare there were large differences observed against the control group in the overall activity. Activity of marked individuals was significantly reduced and they preferred hiding. The influence of polish and marker on the overall frequencies of behavioural categories was evident, mainly in feeding, resting and hiding. The influence on the frequency of exploring was significant in the polish marked group only.

    Marrubium vulgare (Lamiaceae) is a plant traditionally used for the treatment of diabetes in Algeria. Compositional analysis of the aqueous infusion revealed the presence of fifteen metabolites, all belonging to the class of polyphenols. Particularly, seven flavonoids have been detected, together with 5-caffeoylquinic (chlorogenic) acid in small amounts; the extract is dominated by the presence of a series of complex molecules, characterized as verbascoside (acteoside) derivatives. Concerning the anti-diabetic effectiveness a series of in vivo experiments were carried out on albinos Wistar rats. Diabetes was induced in the animals by intra-peritoneal injection of alloxane; they were treated twice a day with aqueous extract from aerial part infusion (100, 200 and 300 mg/kg body weight) and glibenclamide (5mg/kg body weight) for 15 days. Oral administration of 200 and 300 mg/kg body weight of aqueous extract the Marrubium vulgare induced an significant effect antidiabetic and antihyperlipidemic (dose-dependent effect). A decrease in blood glucose by 50% for the dose 100 mg/kg and more than 60% for doses 200 and 300 mg/kg, as well as a significant lowering of total lipids, triglycerides, and total cholesterol levels in treated animals, compared with diabetic controls group (p<0.001), have been observed. Glibenclamide was used as reference and showed similar effects. PMID:22100836

    We have shown previously that Marrubium vulgare, a medicinal plant employed frequently in folk medicine to treat a variety of ailments, exhibits antispasmodic and antinociceptive effects in different experimental models. This work describes the antinociceptive profile of marrubiin, the main constituent of this plant, which was analysed in some models of nociception in mice. The results showed that marrubiin exhibits potent and dose-related antinociceptive effects, whose calculated ID50 values (micromol/kg, i.p.) were the following: 2.2 in the writhing test, 6.6 (first phase) and 6.3 (second phase) in the formalin-induced pain test and 28.8 when evaluated in the capsaicin test. It was more potent than some well-known analgesic drugs. The antinociception produced by the marrubiin was not reversed by naloxone when analyzed against the writhing test. In the hot-plate test, marrubiin did not increase the latency period of pain induced by the thermal stimuli. Its exact mechanism of action remains to be determined, but the results suggest that marrubiin, like hydroalcoholic extract of M. vulgare, does not interact with opioid systems. PMID:10839213

    In this study, the lipophilic and hydrophilic phenol composition of virgin olive oils (VOO) obtained from olives from two of the most important Portuguese cultivars ('Galega Vulgar' and 'Cobrançosa'), harvested at different ripening stages and under two irrigation schemes (rain fed and irrigated), was evaluated. Phenolic alcohols (hydroxytyrosol and tyrosol), phenolic acids and derivatives and flavonoids (luteolin and apigenin), as well as tocopherols were quantified. Lipophilic (>300mgkg(-1)) and hydrophilic phenols (>600mgkg(-1)) were present in high contents in both VOO, for early ripening stages. Gamma-tocopherol content is higher in 'Galega Vulgar' VOO. Total phenols showed a decrease between ripening index 2.5 and 3.5. The dialdehydic form of elenolic acid linked to hydroxytyrosol (3,4-DHPEA-EDA), also known as oleacein, was the major phenolic compound identified in both oils. The concentration of free hydroxytyrosol and tyrosol in both VOO is very low while their esterified derivatives, like 3,4-DHPEA-EDA and p-HPEA-EDA, are much more abundant. PMID:27283606

    Full Text Available The single and combined effects of copper (Cu and cadmium (Cd (0.1-10 mg L−1 in spring barley (Hordeum vulgare L. plants grown in hydroponics are investigated. The aim of the study was to investigate the interactive effect of the binary mixture of Cu and Cd to the growth of H. vulgare and accumulation of these metals by the plants. Single and combined metal treatment led to major effects in the growth of roots and shoots and dry weight of barley. Exposure to metals altered the content of photosynthetic pigments and caused lipid peroxidation. It was observed that combined effects of heavy metals to plants are endpoint and concentration depending. The binary mixture Cu+Cd exhibited additive or less than additive interaction for dry weight, root length and shoot height. Analysis of tissue metal concentrations showed that Cu and Cd were mainly accumulated in the roots and the combination of Cu+Cd had less than additive response of metal bioaccumulation in the leaves and roots.

    Pythium insidiosum is the etiologic agent of pythiosis, a severe and emerging disease that affects mammals. Failure of conventional antifungal therapies is partially justified by the absence of ergosterol in the plasma membrane of this oomycete. Despite research advancement, the treatment of pythiosis has not been not fully established. The present study investigated the in vitro susceptibility profile of Brazilian isolates of P. insidiosum (n = 20) against Melaleuca alternifolia, Mentha piperita and Origanum vulgare essential oils, and their combinations. Susceptibility tests were performed according to CLSI M38-A2 protocol, and combinations were evaluated by the microdilution cherkerboard method. All tested essential oils showed antimicrobial activity against P. insidiosum, and the greatest activity of O. vulgare was highlighted. Synergistic and/or indifferent effect was observed for all combinations evaluated, especially the M. piperita and O. vulgare combination, which showed 65 % synergism. This is the first study to report in vitro combinations of essential oils against P. insidiosum indicating the susceptibility of this oomycete to M. alternifolia, M. piperita and O. vulgare essential oils, as well as their combinations.

    American taxa of the same sections suggest a rather close relationship and support that the biological basis for their classification with different sections is questionable. C-banding patterns identified the chromosomes of parental genomes in interspecific hybrids between the two species and H. vulgare....... The hybrids were stably aneuploid. Both had lost and acquired H. vulgare chromosomes. Thus, somatic elimination of chromosomes was combined with multiplication of chromosomes. The observations of stably aneuploid hybrids have implications for the exploitation of alien germplasm. The activity of non-H. vulgare...

    Full Text Available Abstract Background In order to validate its antiseptic and anticancer properties with respect to traditional uses, we have screened for the first time the antimicrobial activity of aerial parts of M. vulgare L. essential oil against different pathogenic microorganisms and the cytotoxic activity against HeLa cell lines. Methods The agar disk diffusion method was used to study the antibacterial activity of M. vulgare essential oil against 12 bacterial and 4 fungi strains. The disc diameters of zone of inhibition (DD, the minimum inhibitory concentrations (MIC and the concentration inhibiting 50% (IC50 were investigated to characterize the antimicrobial activities of this essential oil. The in vitro cytotoxicity of M. vulgare essential oil was examined using a modified MTT assay; the viability and the IC50 were used to evaluate this test. Results The antimicrobial activity of the essential oil was investigated in order to evaluate its efficacy against the different tested microorganisms. The present results results showed a significant activity against microorganisms especially Gram (+ bacteria with inhibition zones and minimal inhibitory concentration values in the range of 6.6-25.2 mm and 1120-2600 μg/ml, respectively, whereas Gram (- bacteria exhibited a higher resistance. As far as the antifungal activity, among four strains tested, Botrytis cinerea exhibited the strongest activity with inhibition zones of 12.6 mm. However, Fusarium solani, Penicillium digitatum and Aspergillus niger were less sensitive to M. vulgare essential oil. About the citotoxicity assay, this finding indicate the capability of this essential oil to inhibited the proliferation of HeLa cell lines under some conditions with IC50 value of 0.258 μg/ml. Conclusion This investigation showed that the M. vulgare essential oil has a potent antimicrobial activity against some Gram (+ pathogenic bacteria and Botrytis cinerea fungi. The present studies confirm the use of this

    Full Text Available Bacillus strains have been widely used as the companion strain of Ketogulonigenium vulgare in the process of vitamin C fermentation. Different Bacillus strains generate different effects on the growth of K. vulgare and ultimately influence the productivity. First, we identified that Bacillus endophyticus Hbe603 was an appropriate strain to cooperate with K. vulgare and the product conversion rate exceeded 90% in industrial vitamin C fermentation. Here, we report the genome sequencing of the B. endophyticus Hbe603 industrial companion strain and speculate its possible advantage in the consortium. The circular chromosome of B. endophyticus Hbe603 has a size of 4.87 Mb with GC content of 36.64% and has the highest similarity with that of Bacillus megaterium among all the bacteria with complete genomes. By comparing the distribution of COGs with that of Bacillus thuringiensis, Bacillus cereus and B. megaterium, B. endophyticus has less genes related to cell envelope biogenesis and signal transduction mechanisms, and more genes related to carbohydrate transport and metabolism, energy production and conversion, as well as lipid transport and metabolism. Genome-based functional studies revealed the specific capability of B. endophyticus in sporulation, transcription regulation, environmental resistance, membrane transportation, extracellular proteins and nutrients synthesis, which would be beneficial for K. vulgare. In particular, B. endophyticus lacks the Rap-Phr signal cascade system and, in part, spore coat related proteins. In addition, it has specific pathways for vitamin B12 synthesis and sorbitol metabolism. The genome analysis of the industrial B. endophyticus will help us understand its cooperative mechanism in the K. vulgare-Bacillus strain consortium to improve the fermentation of vitamin C.

By comparing the distribution of COGs with that of Bacillus thuringiensis, Bacillus cereus and B. megaterium, B. endophyticus has less genes related to cell envelope biogenesis and signal transduction mechanisms, and more genes related to carbohydrate transport and metabolism, energy production and conversion, as well as lipid transport and metabolism. Genome-based functional studies revealed the specific capability of B. endophyticus in sporulation, transcription regulation, environmental resistance, membrane transportation, extracellular proteins and nutrients synthesis, which would be beneficial for K. vulgare. In particular, B. endophyticus lacks the Rap-Phr signal cascade system and, in part, spore coat related proteins. In addition, it has specific pathways for vitamin B12 synthesis and sorbitol metabolism. The genome analysis of the industrial B. endophyticus will help us understand its cooperative mechanism in the K. vulgare-Bacillus strain consortium to improve the fermentation of vitamin C.

    Full Text Available Essential oils are well known as strong antimicrobial agents of plant origin. In spite of this, the antimicrobial synergism of essential oils isolated from different plant species is poorly investigated. The following study examines the synergism of the essential oils of Origanum vulgare L. and Thymus vulgaris L against pathogenic bacteria, Staphylococcus aureus and Salmonella typhimurium. First, the antibacterial effect of the oils was tested, and the minimal inhibitory concentrations (MIC of both oils were determined using the microdilution method. To test whether the oils act synergistically, every possible combination of essential oil concentrations was used in a dynamic checkerboard method. The results indicated that the oils indeed acted synergistically with fractional inhibitory concentration indexes of 0.45 and 0.50. [Projekat Ministarstva nauke Republike Srbije, br. 173032

    Oregano (Thymbra capitata and Origanum vulgare) essential oils (EOs), cultivated and extracted in the South-East of Spain, were analysed by GC/MS to determine their composition. (E)-β-Caryophyllene (0.5-4.9%), thymol (0.2-5.8%), p-cymene (3.8-8.2%), γ-terpinene (2.1-10.7%) and carvacrol (58.7-77.4%) were determined as the main molecules. This characterisation was completed with enantioselective gas chromatography, where (-)-(E)-β-caryophyllene, (+)-a- pinene and (+)-β-pinene were determined as the main enantiomers. Antioxidant activity was evaluated positively by several methods, accounting for activity against free radicals and reducing power. Important inhibitory activity on lipoxygenase (LOX) and acetylcholinesterase (AChE) was observed supporting potential anti-inflammatory, anti-Alzheimer and insecticidal activities, mainly due to carvacrol. These properties support the potential use of oregano EOs as natural cosmetic and natural pharmaceutical ingredients. PMID:26996035

    1998-05-01

    Accumulation of furanic labdane diterpenes has been investigated in different parts of field-grown plants of MARRUBIUM VULGARE (Lamiaceae) and LEONURUS CARDIACA (Lamiaceae). Furanic labdane diterpenes were produced and accumulated only in the aerial parts. Greatest amounts were measured in leaves and flowers. Up to 4 mg furanic labdane diterpenes per g fresh weight were found. Accumulation of furanic labdane diterpenes in plantlets seemingly depends on a developmental programme. No furanic labdane diterpenes were detected in plantlets during the first four to five weeks following germination. At this time the leaves became more differentiated and the number of trichomes on leaves was obviously increasing. Young leaves and buds contained most furanic labdane diterpenes. It was proven that at least a part of the non-volatile furanic labdane diterpenes is stored in peltate glandular trichomes. NMR signals of marrubiin were investigated with correlated spectra. Some (1)H- and (13)C-NMR assignments reported in literature were revised. PMID:17253250

    Marrubiin, a furane labdane diterpene, is the main analgesic compound present in Marrubium vulgare, a medicinal plant used in Brazil and other countries to treat several ailments. Considering its important pharmacological action, as well as its high yield, some structural modifications were performed in order to obtain more active compounds. Success was obtained in reducing the lactonic function, in the formation of marrubiinic acid and two esterified derivatives, which exhibited significant analgesic effect against the writhing test in mice. Marrubiinic acid showed better activity and excellent yield, and its analgesic effect was confirmed in other experimental models of pain in mice, suggesting its possible use as a model to obtain new and potent analgesic agents.

    The potential of chitosan as a possible booster of the antimicrobial activity of Origanum vulgare EO (OEO) against spoilage bacteria and Listeria monocytogenes was investigated in fresh pork meat. Pork fillets were inoculated with 3 L. monocytogenes strains, dipped either in Origanum vulgare (oregano) Essential Oil (OEO) at 2 and 4%, or in chitosan 1% alone or added with 2 and 4% OEO, then packed under modified atmosphere (70% O2, 20% CO2, 10% N2) and stored at 4 °C for 15 days. OEO did not reduce L. monocytogenes growth, while 2 Log decrease was obtained after 2 days of storage in treatments with chitosan alone or with OEO, with growth inhibition up to day 15 in samples with chitosan and OEO 4%. When OEO was combined with chitosan, total viable counts and spoilage bacteria were reduced and contained over time, particularly Pseudomonas (2.0 Log CFU/g at day 15) and Brochothrix thermosphacta (undetectable). All the treatments applied extended meat shelf-life with respect to control, whose commercial shelf-life was 10 days. Chitosan treatments enhanced L* and maintained a* values almost stable during storage. Chitosan and OEO singly applied reduced lipid oxidation (0.62-0.75 mg malondialdehyde/Kg meat) compared to control (0.99 mg malondialdehyde/Kg meat). Finally, chitosan treated samples were not recognized with respect to the control, whereas OEO gave bitter taste; chitosan with OEO instead mitigated the effect of OEO addition to meat. Chitosan combined with OEO boosts its antimicrobial activity and shows a potential for application in industrial production of fresh pork in MAP, to achieve shelf-life extension, control of L. monocytogenes growth, stability of color and protective effect from oxidation, with low sensory impact.

    Full Text Available Due to general growing resistance and side effects to common antifungal drugs nowadays, there have been many studies reported on the use of herbal essential oils as antifungal agents in recent years. In this study, essential oils of Origanum vulgare and Rosmarinus officinalis (Lamiaceae were examined for their in vitro antifungal activity against three Candida albicans strains (laboratory - CAL, human pulmonary - CAH, and reference ATCC10231-CAR in comparison to Nystatin (0.30 mg/ml and Fluconazole (2 mg/ml as standard antifungal agents. The antifungal activity was evaluated by comparing inhibition zone diameters obtained both by disc-and well-diffusion assays, as well as by comparing MIC and MBC values detected by microdilution assay. Diffusion test results revealed stronger antifungal effect of O. vulgare against all analyzed C. albicans strains identifying CAL strain as the most susceptible one. Inhibition zones ranged from 12.65 to 25.10 mm depending on the concentrations applied. The highest concentrations of Rosemary essential oil (5.00 mg/ml demonstrated activity against two strains: CAL and CAR ATCC 10231 in both diffusion assays applied, while no antifungal activity was recorded against CAH isolate. Microdilution assay showed that both oils demonstrated the same MIC values for all tested strains (0.11 mg/ml, except MIC value against ATCC strain (0.23 mg/ml obtained for Rosemary essential oil. The obtained results indicated that oregano and rosemary essential oils might be highly effective in the natural prevention treatment of candidiasis, although toxicity assays should be previously preformed.

    Cadmium tolerance of three populations of Echium vulgare L., naturally occurring on two Zn-Pb waste deposits (metallicolous populations M1, M2) and on an uncontaminated site (non-metallicolous population, NM) was investigated. The plants were cultivated in hydroponics at 0, 5, 15, 30, or 50μM Cd for 14 days. Although Cd reduced the content of photosynthetic pigments indifferently in the three populations, plant growth parameters and root viability analyses confirmed different Cd tolerances decreasing in the order M1>M2>NM in the populations studied. Organic acids (tartrate, malate, citrate, succinate) were not responsible for the elevated Cd tolerance of the metallicolous populations, although malate and citrate might participate in Cd detoxification in the roots of the M1 and M2. Phytochelatin concentrations were higher in the roots of M1 and M2 populations of E. vulgare, suggesting their role in Cd detoxification and different Cd tolerances. PMID:24732029

    从粗俗语概念功能和人际功能的角度探讨粗俗语“被任何一个社会或民族所禁止或不提倡,但却任何一个人或民族毫不例外地习得或承传了粗俗语”的悖论。粗俗语的概念意义都具备粗、俗、不雅、不悦等意义,但粗俗语具备攻击他人,保护自己的功能;表达喜怒哀乐恨等情绪的功能;实现人与人之间拉近距离或亲近的功能;和实现各种角色等功能。粗俗语具有模糊性,是模糊理论研究的范畴。粗俗语不需要刻意去学,自然就会。%from the perspective of the ideational and personal functions of vulgar expressions, the paradox is observed that the vulgar expressions are ferbidden or not promoted in any society or nation, but are without exception picked up or inherited by everyone in a society or nation. Vulgarism is one of the means of realizing the personal functions: to attack other people and protect selves, to express or let off happiness, anger, sorrow, joy, hatred and so on, to shorten the distance or enhance the intimateness between speakers, and to realize the different roles such as sexual distinction, social status or authority, and nationalities. Vulgar expressions don't need learning, but naturally picked up.

    Isoproterenol injection (100 mg/kg; sc) produced changes in ECG pattern including ST-segment elevation and suppressed R-amplitude. The methanolic extract of M. vulgare at doses of 10, 20, and 40 mg/kg significantly amended the ECG changes. A severe myocardial necrosis and edematous along with a sharp reduction in the arterial blood pressure, left ventricular contractility (LVdP/dt(max or min)), but a marked increase in the left ventricular end-diastolic pressure (LVEDP) were seen in the isoproterenol group. All parameters were significantly improved by the extract treatment. The extract (10 mg/kg) strongly increased LVdP/dt(max). Similarly, treatment with 40 mg/kg of M. vulgare lowered the elevated LVEDP and the heart to body weight ratio. In addition to in vitro antioxidant activity, the extract suppressed markedly the elevation of malondialdehyde levels both in serum and in myocardium. The results demonstrate that M. vulgare protects myocardium against isoproterenol-induced acute myocardial infarction and suggest that the effects could be related to antioxidant activities.

    Isoproterenol injection (100 mg/kg; sc) produced changes in ECG pattern including ST-segment elevation and suppressed R-amplitude. The methanolic extract of M. vulgare at doses of 10, 20, and 40 mg/kg significantly amended the ECG changes. A severe myocardial necrosis and edematous along with a sharp reduction in the arterial blood pressure, left ventricular contractility (LVdP/dt(max or min)), but a marked increase in the left ventricular end-diastolic pressure (LVEDP) were seen in the isoproterenol group. All parameters were significantly improved by the extract treatment. The extract (10 mg/kg) strongly increased LVdP/dt(max). Similarly, treatment with 40 mg/kg of M. vulgare lowered the elevated LVEDP and the heart to body weight ratio. In addition to in vitro antioxidant activity, the extract suppressed markedly the elevation of malondialdehyde levels both in serum and in myocardium. The results demonstrate that M. vulgare protects myocardium against isoproterenol-induced acute myocardial infarction and suggest that the effects could be related to antioxidant activities.

    The studies of Armadillidium vulgare as pest are virtually null worldwide. However under no-tillage systems this species has found an adequate environment for its development and it has become an important pest in some crops in Argentina. It has been shown that the composition of vegetables affects the isopods biology. Our hypothesis was that soybean leaf litter has high nutritive value which allows A. vulgare to grow faster, survive longer, and have higher fecundity favoring the population i...

    Fanny Beauché

    Full Text Available Mate choice is mediated by many components with the criteria varying across the animal kingdom. Chemical cues used for mate attractiveness can also reflect mate quality. Regarding the gregarious species Armadillidium vulgare (isopod crustacean, we tested whether individuals can discriminate conspecifics at two different levels (between sex and physiological status based on olfactory perception. Tested conspecifics were individuals of the same or opposite sex, with the females at different moult stages. We found that the attractiveness of individuals was mediated by short-distance chemical cues and tested individuals were able to discriminate and prefer individuals of the opposite sex. Moreover, male preference to female increased during their moulting status as they matured. Males were particularly more attracted by females with appearing white calcium plates, which corresponds to the beginning of their higher receptivity period. These differences in attractiveness due to sex and physiological status are likely to shape the composition of aggregates and facilitate mate finding and optimize the reproductive success for both males and females. Thus aggregation pheromones could be linked to sex pheromones in terrestrial isopods.

    Full Text Available Generation mean analysis was performed using three crosses namely DL 88 x K 560, K 603 x Azad, RD 2552 x NDB 1020 to study the nature and magnitude of gene effects for yield and its component characters in barley (Hordeum vulgare L.. The F1, F2, BC1 and BC2 of these crosses along with P1 and P2 were studied for six morphological traits. Additive x additive (i epistatic effect was more important and higher than the dominance x dominance (l epistatic effect in the inheritance of no. of effective tillers/plant in DL88 x K560, length of main spike and grain yield/plant in RD 2552 x NDB1020. The length of main spike, weight of grains/main spike, 1000-grain weight and grain yield/plant were significantly higher in RD 2552 x NDB 1020.Thus, these characters were mainly under the control of dominance x dominance (l type of epistasis. Therefore, selection for these characters would be fruitful, if delayed till dominance and epistasis effects are reduced to minimum. The additive × additive (i type gene interaction and duplicate epistasis also seen in this trait suggest the possibilities of obtaining transgressive segregants in later generations. The study revealed the importance of both additive and non-additive types of gene interaction for all the traits studied.

    Any improvement in agricultural systems that results in higher production should also reduce negative environmental impacts and enhance sustainability. The aim of this research was to investigate the effect of two different production systems, one open-field and the other shade-enclosure with four bocashi doses, in order to find the best environmental option in terms of yield, physiological and morphometric characteristics in one oregano (Origanum vulgare L.) cultivar. In this study a completely randomized block design was used with four replications and evaluated for photosynthetic and transpiration rate, stomatal conductance, chlorophyll, leaf area and temperature, aerial and roots fresh and dry biomass, fresh and dry yield. The results showed that oregano adapted best to the shade-enclosure with increase yield of fresh and dry leaf weight of 165% and 118%, respectively, when compared to open-field. Also, higher doses of bocashi improved yield in both environments but more so in shade-enclosure. Soil moisture retention was higher in shade-enclosure which was reflected in physiological variables for soil matric potential, transpiration, stomatal conductivity, photosynthesis being significantly higher in shade-enclosure compared to open-field, thus improving yield. It seems that oregano plants can be grown and perform better under shade-enclosure than open-field and bocashi is a suitable organic fertilizer. PMID:26257756

    Comparative cytogenetic analysis was performed with four alloplasmic recombinant (Hordeum vulgare)-Triticum aestivum lines differing in morphological traits, number of seeds per spike, and seed plumpness. None of the lines displayed introgression of the barley genetic material: the karyotypes included only common wheat chromosomes. Two lines, 79(B) and 79(D), were cytogenetically stable. Plants of lines 79(A) and 79(C) displayed a high frequency of unbalanced chromosome aberrations, including dicentric and polycentric chromosomes, terminal deletions varying in size, acentric fragments, and multiple unidentifiable translocations. Previous studies of the mitochondrial genome showed that the two cytologically unstable lines, which were also unstable in fertility and viability, are characterized by heteroplasmy at the mitochondrial 18S-5S locus (simultaneous presence of barley and wheat fragments). Stable lines 79(B) and 79(D) with normal fertility contained only wheat mitochondrial markers. It was assumed that the substantial instability of the nuclear genome in lines 79(C) and 79(A) was a result of nuclear-cytoplasmic incompatibility and was associated with heteroplasmy, while elimination or considerable reduction of barley material in the mitochondrial genome stabilized the nuclear genome of lines 79(B) and 79(D). In turn, the instability of the nuclear genome was responsible for a decrease in viability and fertility of plants. PMID:16583704

  9. Evaluation of barley (hordeum vulgare l.) germplasm for high forage production under salt stress

    International Nuclear Information System (INIS)

    To explore high biomass producing salt tolerant cultivars of a potential forage crop barley (Hordeum vulgare L.), 30-day old plants of 105 different accessions from different origin were subjected to saline and non-saline (control) conditions for 45 days. Salinity stress (150 mM NaCl) markedly suppressed plant growth (shoot and/or root fresh and dry weights), chlorophyll pigments (a and b), internal CO/sub 2/ concentration, stomatal conductance, rate of transpiration and photosynthesis, while a considerable salt-induced increase was observed in all fluorescence related attributes including efficiency of photosystem-II (Fv/Fm), co-efficient of non-photochemical quenching (QN), photochemical quenching (QP), and non-photochemical quenching (NPQ) in all 105 accessions of barley. The response of all 105 barley accessions to salt stress varied significantly for all the morpho-physiological attributes determined in the present study. Overall, on the basis of shoot and root dry weights, accessions, 4050, 4053, 4056, 4163, 4228, 4229, 4244, 4245, 4290, 4414, 4415, 4427, 4452, Mahali, Jesto, 4165, 4229, 4249, 4405, 4409, 4426, 4456, and Giza 123 were found superior while accessions, 4245, 4158, 4166, 4246, 4406, 4423, 4441, 4442 4447, 4453 and 4458 inferior under saline conditions.

    Full Text Available Triticum vulgare (Wheat based products are the major dietary source of food in developing countries. In India, it grows in association with boundary plantations of Populus deltoids (poplar. During winter, poplar enters in dormancy which cause a heavy leaf fall at the time of wheat seed germination. Large number of poplar senescence leaves may adversely affect the wheat. Therefore, the present study was performed to examine the effect of senescence poplar leaves on wheat germ and some other biochemical parameters. Seed’s germination rate was determined by measuring root and shoot lengths, percent germination, germination index, and inhibition percentage. Biochemical parameters, namely, pigment, carbohydrate, protein, and phenol content, were estimated. Activities of catalase and polyphenol oxidase which are stress marker enzymes were also measured. Results revealed that germination and other biochemical parameters of wheat were severely affected by senescence poplar leaves even at very low concentration. So, intercropping of poplar along with wheat may be chosen carefully as wheat is the major dietary staple.

  11. Reduction of gramine concentration by gamma-irradiation in seedlings of Hordeum vulgare var. Amaginijo

    International Nuclear Information System (INIS)

    The effects of gamma-irradiation on gramine concentration in seedlings of barley (Hordeum vulgare var. Amaginijo) were investigated. Similarly to other barley cultivars, this amine appeared in shoots of sprouting seedlings and its concentration increased in the course of subsequent development to attain a maximum around the ninth day. Exposure of two-day-old seedlings to gamma-radiation resulted in significant reductions of the concentration as compared with non-irradiated control, dependent upon the radiation dose, whilst the five-day-old seedlings were slightly affected. Seeds were more radioresistant than younger seedlings, when the decline in gramine quantity was taken as a marker of radiation effect. Longer storage of irradiated seeds enhanced the decrease of this compound in seedlings. At relatively low doses, gramine concentration was successively recovered to reach the control level during further growth. This decline of gramine content could not be correlated solely with water content of seeds and oxygen did not seem to be a critical factor. On the basis of these results, probable mechanisms for radiation-induced reduction of the amine concentration are discussed. In these experiments it was found that changing patterns of gramine content were in close parallel with those of growth

  12. Barley (Hordeum vulgare) and Kiwicha (Amaranthus caudatus) Improvement by Mutation Induction in Peru

    International Nuclear Information System (INIS)

    In order to increase food availability and household incomes of families in the Andean region of Peru, a mutation induction method was applied to improve barley (Hordeum vulgare) and kiwicha (Amaranthus caudatus) cultivars. Barley cultivar Buenavista was treated with 200 and 300Gy inducing different kinds of mutations. Twenty promising mutant lines were selected and have been evaluated at the national trials. From them Mbv-Earlier, from 300Gy dose was selected and released in 2006 as a new cultivar denominated Centenario. This cultivar has a high yield potential (5,552 kg/ha), resistance to stripe rust (P. striiformis f sp hordei) and better food quality than the parental cultivar. Kiwicha traditional cultivar Seleccion Ancash treated with 400Gy , identified a higher yield mutant denominated Centenario Cultivar. At farmer location in the coast the yield has a variation of 3,500 to 5,500 kg/ha and in the highland from 2,500 to 3,700 kg/ha. The better yield potential, tolerance to Sclerotinia sp, color and size of its grains have contributed in the preference of Centenario over other commercial cultivars. (author)

    Experimental work was carried out under close-to-real conditions to study mercury uptake by Hordeum vulgare L. cultivated in lysimeter experiments. The soil in the lysimeter experiment was obtained from a test plot located near Almadén (Spain) and had a mean mercury content of 22.9 mg kg(-1). A sequence of four crops was sown starting in autumn 2000 and repeated on a yearly basis until 2004. The first crop was grown in the field prior to the extraction of 5 one-cubic-meter lysimeters. The succeeding crops were sown in the lysimeter experiments at the CIEMAT Research Centre (Madrid, Spain). Samples of root and shoot were obtained during the four seasons. Concentrations of mercury at plant maturity in roots vary between I and 3 mg kg(-1) and in straw and grain the concentrations range from 72 to 480 microg kg(-1) and from 5 to 257 microg kg(-1), respectively. In order to assess the potential risk for human health and animal feed, an evaluation of the mercury content in the edible part of the crop has been carried out. According to legislation, there is no human health intoxication risk with a balanced consumption; otherwise, the forage use would have to be controlled. PMID:21972517

    The genetic sources for host-plant resistance to the greenbug (Schizaphis graminum Rondani) in barley (Hordeum vulgare ssp. spontaneum) are limited in that only two single dominant genes Rsg1 and Rsg2 are available for the complex of greenbug biotypes. We evaluated four new barley lines from the Wild Barley Diversity Collection (WBDC) that previously showed potential for greenbug resistance. Three of those entries, WBDC 53, WBDC 117, WBDC 336, exhibited very dominant sources of resistance to older known biotypes B, C, E, F, H, I, and TX1, which also add to the host-plant differentials used to separate these greenbug biotypes. We also re-evaluated the earlier known set of greenbug biotypes that have been in culture for several years against the known host-plant differentials, and included seven newer greenbug isolates collected from Wyoming to the full complement of small grain differentials. This resulted in the discovery of five new greenbug biotypes, WY10 MC, WY81, WY10 B, WY12 MC, and WY86. Wyoming isolates WY4 A and WY4 B were identical in their phenotypic profile, and should be combined as a single unique greenbug biotype. These barley trials resulted in finding new sources of host-plant resistance, although more research needs to be conducted on what type of resistance was found, and how it can be used. We also document that the Wheatland, Wyoming area serves as a very conducive environment for the development of new greenbug biotypes. PMID:26527793

    Oregano is a perennial shrub that grows in the mountains of the Mediterranean and Euro/Irano-Siberian regions. This study was conducted to identify the major constituents of the ethanolic Origanum vulgare extract and examine the cytotoxic, antioxidant, and antibacterial properties of the extract but more importantly the contribution of its specific major constituent(s) or their combination to the overall extract biological activity. Gas chromatography/mass spectroscopy analysis showed that the extract contained monoterpene hydrocarbons and phenolic compounds, the major ones being carvacrol and thymol and to a lesser extent p-cymene, 1-octacosanol, creosol, and phytol. A549 epithelial cells challenged with the extract showed a concentration-dependent increase in cytotoxicity. A combination of thymol and carvacrol at equimolar concentrations to those present in the extract was less cytotoxic. The A549 cells pretreated with nonlethal extract concentrations protected against hydrogen-peroxide-induced cytotoxicity, an antioxidant effect more effective than the combination of equimolar concentrations of thymol/carvacrol. Inclusion of p-cymene and/or 1-octacosanol did not alter the synergistic antioxidant effects of the carvacrol/thymol mixture. The extract also exhibited antimicrobial properties against Gram-positive and Gram-negative bacterial strains including clinical isolates. In conclusion, the oregano extract has cytotoxic, antioxidant, and antibacterial activities mostly attributed to carvacrol and thymol. PMID:27051475

  16. Treatment of patients with vulgar psoriasis through electromagnetic field of extremely low frequency

    International Nuclear Information System (INIS)

    A controlled and randomized clinical therapeutical assay in phase III was carried out in 52 patients with vulgar psoriasis, who were assisted in the Dermatology department of 'Dr Joaquin Castillo Duany' Clinical Surgical Hospital in Santiago de Cuba, from 2005 to 2010 who were divided into 2 groups (26 members each): the active group which was conventionally treated with 20% cade ointment; and the experimental group, to which the extremely low frequency electromagnetic field was applied, with the objective of determining the effectiveness of this field in those affected during the periods of crisis and intercrisis. The studied population was clinically characterized by means of a frequency analysis, while the hypothesis tests were used for the evaluation of proportions which null hypothesis were accepted with 5 % as maximum error. In the series the used field was effective to treat the disorder during crisis and more effective than the cade ointment to prolong the intercrisis stage, without causing adverse reactions, so that it constituted a new alternative therapy that can be generalized in the dermatological services of the country, in order to improve the life quality of those who suffer that dermatosis

    Three methoxylated flavones isolated from Marrubium peregrinum - ladanein, scutellarein-5,7,4'-trimethyl ether, and scutellarein-5,6,7,4'-tetramethyl ether - were assayed for their cytotoxicity towards a recently developed dasatinib-resistant murine leukemia cell line (DA1-3b/M2 (BCR-ABL)), together with the structurally related non-methylated flavone scutellarein. The most active compound, ladanein, was looked for in 20 common Lamiaceae species by a quick HPLC screening. Among the possible positive results, the most interesting source was found to be Marrubium vulgare, which led to the isolation and identification of ladanein for the first time in this species. Ladanein also displayed moderate (20-40 microM) activities against K562, K562R (imatinib-resistant), and 697 human leukemia cell lines but was toxic neither to MOLM13 nor to human peripheral blood mononuclear cells. This work provides a common natural source for the hemi-synthesis of future ladanein-derived flavones and the study of their antileukemic activity. PMID:19644796

    Full Text Available In the present study, genetic diversity in seven cultivars of cultivated barley (Hordeum vulgare populations was evaluated using 10 microsatellite markers. Genomic DNA was extracted from fresh leaves and amplification reactions were done by PCR. The amplification products were separated on 6% denaturing polyacrylamide gels containing 7M urea and visualized via silver staining method. High level of polymorphism was observed among populations. Polymorphic bands ranged from 100 to 300 bp. Altogether 65 alleles were observed among all genotypes, with an average of 9.2 alleles per locus for all loci. Polymorphic information content (PIC ranged from 0.80 to 0.88 with an average of 0.84. �Sahand� populations showed the lowest mean of gene diversity whereas the highest mean of heterozygosity observed in Rayhan populations that can prepare a powerful resource of genetic diversity for breeding programs. The genotypes were clustered using unweight pair-group method on arithmetic average by POPGEN32 software. The dendrogram discriminated all the genotypes in several groups. The results showed that SSR markers have a high ability to reveal most of the information in a single locus and can be used for genetic analysis in molecular levels determination of genetic similarity and clustering barley cultivars.

The aim of this research was to investigate the effect of two different production systems, one open-field and the other shade-enclosure with four bocashi doses, in order to find the best environmental option in terms of yield, physiological and morphometric characteristics in one oregano (Origanum vulgare L. cultivar. In this study a completely randomized block design was used with four replications and evaluated for photosynthetic and transpiration rate, stomatal conductance, chlorophyll, leaf area and temperature, aerial and roots fresh and dry biomass, fresh and dry yield. The results showed that oregano adapted best to the shade-enclosure with increase yield of fresh and dry leaf weight of 165% and 118%, respectively, when compared to open-field. Also, higher doses of bocashi improved yield in both environments but more so in shade-enclosure. Soil moisture retention was higher in shade-enclosure which was reflected in physiological variables for soil matric potential, transpiration, stomatal conductivity, photosynthesis being significantly higher in shade-enclosure compared to open-field, thus improving yield. It seems that oregano plants can be grown and perform better under shade-enclosure than open-field and bocashi is a suitable organic fertilizer.

    Agricultural nitrous oxide (N2O) pollution resulting from the use of synthetic fertilizers represents a significant contribution to anthropogenic greenhouse gas emissions, providing a rationale for reduced use of nitrogen (N) fertilizers. Nitrogen limitation results in extensive systems rebalancing that remodels metabolism and defence processes. To analyse the regulation underpinning these responses, barley (Horedeum vulgare) seedlings were grown for 7 d under N-deficient conditions until net photosynthesis was 50% lower than in N-replete controls. Although shoot growth was decreased there was no evidence for the induction of oxidative stress despite lower total concentrations of N-containing antioxidants. Nitrogen-deficient barley leaves were rich in amino acids, sugars and tricarboxylic acid cycle intermediates. In contrast to N-replete leaves one-day-old nymphs of the green peach aphid (Myzus persicae) failed to reach adulthood when transferred to N-deficient barley leaves. Transcripts encoding cell, sugar and nutrient signalling, protein degradation and secondary metabolism were over-represented in N-deficient leaves while those associated with hormone metabolism were similar under both nutrient regimes with the exception of mRNAs encoding proteins involved in auxin metabolism and responses. Significant similarities were observed between the N-limited barley leaf transcriptome and that of aphid-infested Arabidopsis leaves. These findings not only highlight significant similarities between biotic and abiotic stress signalling cascades but also identify potential targets for increasing aphid resistance with implications for the development of sustainable agriculture.

    The aim of this study was to investigate the bioactivity of the essential oil isolated from Origanum vulgare L. (EOv). We analyzed the in vivo anti-inflammatory properties in a mouse-airway inflammation model and the in vitro antimicrobial activity, genotoxicity over the anaphase-telophase with the Allium cepa strain and its cytotoxicity/viability in A549 culture cells. In vivo, EOv modified the levels of tumor necrosis factor -α and viable activated macrophages and was capable to mitigate the effects of degradation of conjugated dienes. In vitro, EOv reduced the viability of cultured A549 cells as well as the mitotic index and a number of chromosomal aberrations; however, it did not change the number of phases. We found that EOv presents antimicrobial activity against different Gram (-) and (+) strains, measured by disc-diffusion test and confirmed with a more accurate method, the AutoCad software. We postulate that EOv presents antibacterial, antioxidant and chemopreventive properties and could be play an important role as bioprotector agent. PMID:25266989

    The geographic distribution of genetic diversity can reveal the evolutionary history of a species. For crop plants, phylogeographic patterns also indicate how seed has been exchanged and spread in agrarian communities. Such patterns are, however, easily blurred by the intense seed trade, plant improvement and even genebank conservation during the twentieth century, and discerning fine-scale phylogeographic patterns is thus particularly challenging. Using historical crop specimens, these problems are circumvented and we show here how high-throughput genotyping of historical nineteenth century crop specimens can reveal detailed geographic population structure. Thirty-one historical and nine extant accessions of North European landrace barley (Hordeum vulgare L.), in total 231 individuals, were genotyped on a 384 single nucleotide polymorphism assay. The historical material shows constant high levels of within-accession diversity, whereas the extant accessions show more varying levels of diversity and a higher degree of total genotype sharing. Structure, discriminant analysis of principal components and principal component analysis cluster the accessions in latitudinal groups across country borders in Finland, Norway and Sweden. FST statistics indicate strong differentiation between accessions from southern Fennoscandia and accessions from central or northern Fennoscandia, and less differentiation between central and northern accessions. These findings are discussed in the context of contrasting historical records on intense within-country south to north seed movement. Our results suggest that although seeds were traded long distances, long-term cultivation has instead been of locally available, possibly better adapted, genotypes. PMID:25227257

    Agricultural nitrous oxide (N2O) pollution resulting from the use of synthetic fertilizers represents a significant contribution to anthropogenic greenhouse gas emissions, providing a rationale for reduced use of nitrogen (N) fertilizers. Nitrogen limitation results in extensive systems rebalancing that remodels metabolism and defence processes. To analyse the regulation underpinning these responses, barley (Horedeum vulgare) seedlings were grown for 7 d under N-deficient conditions until net photosynthesis was 50% lower than in N-replete controls. Although shoot growth was decreased there was no evidence for the induction of oxidative stress despite lower total concentrations of N-containing antioxidants. Nitrogen-deficient barley leaves were rich in amino acids, sugars and tricarboxylic acid cycle intermediates. In contrast to N-replete leaves one-day-old nymphs of the green peach aphid (Myzus persicae) failed to reach adulthood when transferred to N-deficient barley leaves. Transcripts encoding cell, sugar and nutrient signalling, protein degradation and secondary metabolism were over-represented in N-deficient leaves while those associated with hormone metabolism were similar under both nutrient regimes with the exception of mRNAs encoding proteins involved in auxin metabolism and responses. Significant similarities were observed between the N-limited barley leaf transcriptome and that of aphid-infested Arabidopsis leaves. These findings not only highlight significant similarities between biotic and abiotic stress signalling cascades but also identify potential targets for increasing aphid resistance with implications for the development of sustainable agriculture.

    Three methoxylated flavones isolated from Marrubium peregrinum - ladanein, scutellarein-5,7,4'-trimethyl ether, and scutellarein-5,6,7,4'-tetramethyl ether - were assayed for their cytotoxicity towards a recently developed dasatinib-resistant murine leukemia cell line (DA1-3b/M2 (BCR-ABL)), together with the structurally related non-methylated flavone scutellarein. The most active compound, ladanein, was looked for in 20 common Lamiaceae species by a quick HPLC screening. Among the possible positive results, the most interesting source was found to be Marrubium vulgare, which led to the isolation and identification of ladanein for the first time in this species. Ladanein also displayed moderate (20-40 microM) activities against K562, K562R (imatinib-resistant), and 697 human leukemia cell lines but was toxic neither to MOLM13 nor to human peripheral blood mononuclear cells. This work provides a common natural source for the hemi-synthesis of future ladanein-derived flavones and the study of their antileukemic activity.

    Full Text Available The aim of this study is to examine the growth inhibitory effects of methanolic leaf and fruit extracts of L. vulgare on HCT-116 cells over different time periods and their synergistic effect with a Pd(apox complex. The antiproliferative activity of plant extracts alone or in combination with the Pd(apox complex was determined using MTT cell viability assay, where the IC50 value was used as a parameter of cytotoxicity. Results show that antiproliferative effects of L. vulgare extracts increase with extension of exposure time, with decreasing IC50 values, except for 72 h where the IC50 values for methanolic leaf extract were lower than for the fruit extract. The Pd(apox complex alone had a weak antiproliferative effect, but combination with L. vulgare extracts caused stronger effects with lower IC50 values than with L. vulgare extracts alone. The type of cell death was explored by fluorescence microscopy using the acridin orange/ethidium bromide method. Treatments with plant extracts caused typical apoptotic morphological changes in HCT-116 cells and co-treatments with Pd(apox complex caused higher levels of apoptotic cells than treatment with plant extracts alone. The results indicate that L. vulgare is a considerable source of natural bioactive substances with antiproliferative activity on HCT-116 cells and which have a substantial synergistic effect with the Pd(apox complex.

    Photosynthesis is a biological process most affected by water deficit. Plants have various photosynthetic mechanisms that are matched to specific climatic zones. We studied the photosynthetic plasticity of C3 plants at water deficit using ecotypes of Marrubium vulgare L. from high (2,200 m) and low (1,100 m) elevation sites in the Mishou-Dagh Mountains of Iran. Under experimental drought, high-altitude plants showed more tolerance to water stress based on most of the parameters studied as compared to the low-altitude plants. Increased tolerance in high-altitude plants was achieved by lower levels of daytime stomatal conductance (g s) and reduced damaging effect on maximal quantum yield of photosystem II (PSII) (F v /F m ) coupled with higher levels of carotenoids and non-photochemical quenching (NPQ). High-altitude plants exhibited higher water use efficiency (WUE) than that in low-altitude plants depending on the presence of thick leaves and the reduced daytime stomatal conductance. Additionally, we have studied the oscillation in H(+) content and diel gas exchange patterns to determine the occurrence of C3 or weak CAM (Crassulacean acid metabolism) in M. vulgare through 15 days drought stress. Under water-stressed conditions, low-altitude plants exhibited stomatal conductance and acid fluctuations characteristic of C3 photosynthesis, though high-altitude plants exhibited more pronounced increases in nocturnal acidity and phosphoenolpyruvate carboxylase (PEPC) activity, suggesting photosynthetic flexibility. These results indicated that the regulation of carotenoids, NPQ, stomatal conductance and diel patterns of CO2 exchange presented the larger differences among studied plants at different altitudes and seem to be the protecting mechanisms controlling the photosynthetic performance of M. vulgare plants under drought conditions.

    Water extract of Marrubium vulgare is widely used as antihypertensive treatment in folk medicine. We have compared the effect of 10-week-long treatment with amlodipine or Marrubium water extract on systolic blood pressure (SBP), cardiovascular remodeling and vascular relaxation in spontaneously hypertensive rats (SHR). Both treatments produced similar decrease in SBP. Amlodipine treatment reduced left ventricle, aortic and mesenteric artery weight. Marrubium treatment had a significant antihypertrophic effect in aorta only. Relaxation to acetylcholine (ACh) of mesenteric artery was improved by Marrubium but not by amlodipine treatment. These results demonstrate that, in addition to its antihypertensive effect, Marrubium water extract improved the impaired endothelial function in SHR. PMID:15554450

    Full Text Available Response to a high salinity treatment of 300 mM NaCl was studied in a cultivated barley Hordeum vulgare Syrian cultivar Tadmor and in a halophytic wild barley Hordeum marinum. Differential salinity tolerance of H. marinum and H. vulgare is underlied by qualitative and quantitative differences in proteins involved in a variety of biological processes. The major aim was to identify proteins underlying differential salinity tolerance between the two barley species. Analyses of plant water content, osmotic potential and accumulation of proline and dehydrin proteins under high salinity revealed a relatively higher water saturation deficit in H. marinum than in H. vulgare while H. vulgare had lower osmotic potential corresponding with high levels of proline and dehydrins. Analysis of proteins soluble upon boiling isolated from control and salt-treated crown tissues revealed similarities as well as differences between H. marinum and H. vulgare. The similar salinity responses of both barley species lie in enhanced levels of stress-protective proteins such as defence-related proteins from late-embryogenesis abundant (LEA family, several chaperones from heat shock protein (HSP family, and others such as GrpE. However, there have also been found significant differences between H. marinum and H. vulgare salinity response indicating an active stress acclimation in H. marinum while stress damage in H. vulgare. An active acclimation to high salinity in H. marinum is underlined by enhanced levels of several stress-responsive transcription factors from basic leucine zipper (bZIP and nascent polypeptide-associated complex (NAC families.

    To verify the possible involvement of lipids and several other compounds including hydrogen peroxide (H(2)O(2)) and glyceraldehyde-3-phosphate dehydrogenase (G3PDH) in the response of Hordeum vulgare to early potassium deprivation, plants were grown in hydroponic conditions for 30d with a modified Hewitt nutrient solution containing 3mM K(+). They were then incubated for increasing periods of time ranging from 2 to 36h in the same medium deprived of K(+). In contrast to leaves, root K(+) concentration showed its greatest decrease after 6h of treatment. The main lipids of the control barley roots were phospholipids (PL), representing more than 50% of the total lipids. PL did not change with treatment, whereas free sterols (FS) decreased following K(+) deprivation, showing a reduction of approximately 17% after 36h. With respect to the individual PL, 30h K(+) deprivation led to a reduction in phosphatidylcholine (PC), phosphatidylserine (PS), and phosphatidylinositol (PI) levels, whereas phosphatidylglycerol (PG), phosphatidylethanolamine (PE), and phosphatidic acid (PA) levels increased. The maximum PA accumulation and the highest phospholipase D (PLD) activation, estimated by an accumulation of phosphatidylbutanol (PtBut), were observed after 24h of K(+) starvation. At the root level, H(2)O(2) showed the maximum value after 6h of incubation in -K solution. In parallel, G3PDH activity reached its minimum. On the basis of a concomitant stimulation of PLD activity and, consequently, PA accumulation, enhancement of H(2)O(2) production, and inhibition of G3PDH activity, we suggest a possible involvement of these three compounds in an early response to K(+) deprivation.

Nusantara Bioscience 6: 39-44. Pot experiments were carried out during two growth seasons 2010 / 2011 under greenhouse conditions of the National Research Centre, Dokki, Cairo, Egypt to investigate the response of barley plants (Hordium vulgare L grown under salinity stress (2500 or 5000 ppm to spraying with solutions of uniconazole at 150 or 200 ppm. The obtained results showed that irrigation with saline solutions caused increases in the amounts of abscisic acid (ABA, crude protein, total soluble-protein and proline contents. The results showed that spraying barley plants grown under saline solutions with uniconazole increased endogenous hormone contents of ABA, cytokinins, crude protein, total soluble protein and proline but caused decreases in the amounts of endogenous indole acetic acid (IAA and gibberellic acid (GA3. High protection of abscisic acid in treating plants with uniconazole and under salt stress (interaction effect increases proline, proteins and soluble protein which has been proposed to act as compatible solutes that adjust the osmotic potential in the cytoplasm. Thus, these biochemical characters can be used as a metabolic marker in relation to salinity stress.

    Marrubium vulgare and Withania somnifera are used in folk medicine of several countries. Many researches showed that they are used for the treatment of variety of diseases due to their antioxidant effects. The present aim of this study was to evaluate the antihepatotoxic and antioxidant activities of the both extracts against carbon tetrachloride (CCl4)-induced hepatic damage in rats. Both extracts were given orally in a dose of 500 mg/kg/day for 4 weeks along with CCl4 started at the 7th week of induction of hepatotoxicity. The antihepatotoxic activity was assessed by measuring aspartate transaminase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), glutathione peroxidase (GPx), glutathione reductase (GR), glutathione-S-transferase (GST), reduced glutathione (GSH), tissue content and malondialdehyde (MDA) as well as histopathological examination. Both extracts showed a significant antihepatotoxic effect by reducing significantly the levels of AST, ALT and LDH. However, ALP levels were decreased non-significantly. Regarding the antioxidant activity, they exhibited significant effects by increasing the GPx, GR and GST activities with increased GSH tissue contents and decreased production of MDA level. Furthermore, both extracts alleviated histopathological changes in rats' liver treated with CCl4. M. vulgare and W. somnifera protect the rats' liver against CCl4-induced hepatotoxicity. This effect may be attributed, at least in part, to the antioxidant activities of these extracts. PMID:24825994

    The objective of the present study was to elucidate the beneficial properties of aqueous extracts of Marrubium vulgare (AEM) towards cardiovascular disease by protecting human-LDL against lipid peroxidation and promoting HDL-mediated cholesterol efflux. Human-LDL were oxidised by incubation with CuSO(4) in the presence of increased concentrations of AEM (0-100 microg/ml). LDL lipid peroxidation was evaluated by conjugated diene formation, vitamin E disappearance as well as LDL-electrophoretic mobility. HDL-mediated cholesterol efflux assay was carried out in human THP-1 macrophages. Incubation of LDL with AEM significantly prolonged the lag phase (P=0.014), lowered the progression rate of lipid peroxidation (P=0.004), reduced the disappearance of vitamin E and the electrophoretic mobility in a dose-dependent manner. Also, incubation of HDL with AEM significantly increased HDL-mediated cholesterol efflux from THP-1 macrophages implicating an independent ATP binding cassette A1 (ABCA1) pathways. Our findings suggest that M. vulgare provides a source of natural antioxidants, which inhibit LDL oxidation and enhance reverse cholesterol transport and thus can prevent cardiovascular diseases development. These antioxidant properties increase the anti-atherogenic potential of HDL. PMID:17045616

    Cecropia obtusifolia and Marrubium vulgare have been widely used in Mexican traditional medicine for the control of type 2 diabetes. In order to evaluate the clinical effect produced by the aqueous extract from these species on type 2 non-controlled diabetes mellitus, a total of 43 outpatients were included. Based on the European NIDDM (policy group) criteria, only patients with poor response to the conventional treatment were selected. All patients maintained their medical treatment and also received a prepared infusion of the dry leaves of the plant treatment for 21 days. In a double-blind manner, the patients were randomly grouped as follows: 22 patients were treated with C. obtusifolia and 21 with M. vulgare. The fasting blood glucose values were reduced by 15.25% on patients treated with C. obtusifolia, while cholesterol and triglycerides were decreased by 14.62% and 42.0%, respectively (ANOVA pvulgare, the plasma glucose level was reduced by 0.64% and cholesterol and triglycerides by 4.16% and 5.78%, respectively. When the results were compared between groups, significant differences in glucose and cholesterol diminution were found. The obtained results showed that the infusion prepared with the leaves of C. obtusifolia (containing 2.99+/-0.14mg of chlorogenic acid/g of dried plant) produced beneficial effects on carbohydrate and lipid metabolisms when it was administered as an adjunct on patients with type 2 diabetes with poor response to conventional medical treatment.

    Marrubium vulgare and Withania somnifera are used in folk medicine of several countries. Many researches showed that they are used for the treatment of variety of diseases due to their antioxidant effects. The present aim of this study was to evaluate the antihepatotoxic and antioxidant activities of the both extracts against carbon tetrachloride (CCl4)-induced hepatic damage in rats. Both extracts were given orally in a dose of 500 mg/kg/day for 4 weeks along with CCl4 started at the 7th week of induction of hepatotoxicity. The antihepatotoxic activity was assessed by measuring aspartate transaminase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), glutathione peroxidase (GPx), glutathione reductase (GR), glutathione-S-transferase (GST), reduced glutathione (GSH), tissue content and malondialdehyde (MDA) as well as histopathological examination. Both extracts showed a significant antihepatotoxic effect by reducing significantly the levels of AST, ALT and LDH. However, ALP levels were decreased non-significantly. Regarding the antioxidant activity, they exhibited significant effects by increasing the GPx, GR and GST activities with increased GSH tissue contents and decreased production of MDA level. Furthermore, both extracts alleviated histopathological changes in rats' liver treated with CCl4. M. vulgare and W. somnifera protect the rats' liver against CCl4-induced hepatotoxicity. This effect may be attributed, at least in part, to the antioxidant activities of these extracts.

    Full Text Available Morphometrical indexes, and spectrophotometrically measured protein and glutathione (GSH, GSSG contents and activity of peroxidase (POD, EC 1.11.1.7, glutathione-reductase (GR, EC 1.6.4.2 and glutathione S-transferase (GST, EС 2.5.1.18 were examined in Hordeum vulgare L. seedlings after 0.01 and 0.1 mg/l AgNPs treatment during 24 h. We tested the hypothesis that the action of nanoparticles has a stressful effect on the physiological and biochemical processes of seedlings. Growth of roots was inhibited and fresh weight decreased by 29% and 21% under low and high concentrations respectively. Conversely, leaf growth was intensified, and leaf length (16% and 18% and fresh weight (35% and 44% increased at low and high concentrations respectively. POD activity in roots increased by 26% and 7%, and decreased in leaves to 57% and 81% of control at low and high concentrations respectively. GSH content changed insignificantly, but GSSG content increased in roots (2 and 2.5-fold and in leaves (13% and 30% at both AgNPs concentrations. GSH/GSSG-ratio decreased in roots (1.9 and 2.6-fold and in leaves (1.1 and 1.3-fold at low and high concentrations respectively. GR activity decreased at a concentration of 0.01 mg/l (7% in roots and 17% in leaves respectively and increased at 0.1 mg/l (52% in roots and 6% in leaves. GST activity increased in leaves (52% and 78% at low and high concentrations but decreased by 17% in roots under high concentration of nanosilver. Thus, the action of AgNPs on barley seedlings had a dose-dependent and organ-specific character. The various directions of changes in growth, metabolic processes and activity of antioxidant defense systems appear to be a stress response of barley seedlings to the impact of AgNPs, which underlines the necessity of detailed study of plant intracellular processes exposed to the action of nanomaterial.

    Non-denaturing FISH (ND-FISH) was used to compare the distribution of four simple sequence repeats (SSRs)-(AG) n , (AAG) n , (ACT) n and (ATC) n -in somatic root tip metaphase spreads of 12 barley (H. vulgare ssp. vulgare) cultivars, seven lines of their wild progenitor H. vulgare ssp. spontaneum, and four lines of their close relative H. bulbosum, to determine whether the range of molecular diversity shown by these highly polymorphic sequences is reflected at the chromosome level. In both, the cultivated and wild barleys, clusters of AG and ATC repeats were invariant. In contrast, clusters of AAG and ACT showed polymorphism. Karyotypes were prepared after the identification of their seven pairs of homologous chromosomes. Variation between these homologues was only observed in one wild accession that showed the segregation of a reciprocal translocation involving chromosomes 5H and 7H. The two subspecies of H. vulgare analysed were no different in terms of their SSRs. Only AAG repeats were found clustered strongly on the chromosomes of all lines of H. bulbosum examined. Wide variation was seen between homologous chromosomes within and across these lines. These results are the first to provide insight into the cytogenetic diversity of SSRs in barley and its closest relatives. Differences in the abundance and distribution of each SSR analysed, between H. vulgare and H. bulbosum, suggest that these species do not share the same H genome, and support the idea that these species are not very closely related. Southern blotting experiments revealed the complex organization of these SSRs, supporting the findings made with ND-FISH. PMID:23242107

    The fungal pathogen Bipolaris sorokiniana causes a wide spectrum of diseases including spot blotch disease. To achieve a better understanding of the biology of the fungus, the interaction of B. sorokiniana with the host barley (Hordeum vulgare L) and the resulting disease spot blotch...... was investigated. In this PhD work it could be shown that light dependent disease symptoms were associated with less fungal colonization, while suppressing the rate of photosynthesis by keeping plants in darkness made them super-susceptible to B. sorokiniana colonization. Likewise, partial suppression...... of photosynthesis with DCMU (3-(3,4-Dichlorophenyl)-1,1-dimethylurea) reduced the formation of necrosis after infection and led to increased susceptibility, strongly implying that active photosynthesis is involved in disease symptom formation and that these symptoms negatively affect fungal colonization...

    An optimized analytical method based on C8 core-shell reverse phase chromatographic separation and high resolution mass spectral (HRMS) detection is developed for a fast analysis of unbound phytochelatins (PCs) in plants. Its application to analysis of Clinopodium vulgare L. is demonstrated where proper PCs liberating and preservation conditions were employed using dithiotreitol in the extraction step. A baseline separation of glutathione (GSH) and phytochelatins from 2 to 5 (PC2-PC5) for 3 min was achieved at conventional HPLC backpressure, with detection limits from 3 ppt (for GSH) to 2.5 ppb (for PC5). It is shown, that the use of HRMS with tandem mass spectral (MS/MS) capabilities permits additional wide range screening ability for iso-phytochelatins and PC similar compounds, based on exact mass and fragment spectra in a post acquisition manner.

    The androgenic glands (AGs) of malacostracan crustaceans are responsible for differentiation of male sexual characteristics, and sex reversal is readily obtained by implantation of AGs in female crustaceans. In order to induce sex reversal, we implanted inactive AGs (dead cells) into young females of Armadillidium vulgare. Before implantation fresh AGs (living cells) were treated twice with 80% ethanol for 3 min and kept in crustacean physiological saline for 30 s. We refer to these AGs as ethanol-treated AGs (t-AGs). Stage 6 females were used as recipients of t-AG implantation. They received an implant of three t-AGs (3 t-AGs) three times, once each week. Testis formation in recipients was used as an indicator of the masculinized levels of female gonads. Female sexual characteristics were masculinized in proportion to the number of 3 t-AG implantations. Three implantations (total number of t-AGs, nine glands) induced development of testes, penes, and male copulatory organs in the recipient females. Furthermore, they could produce progeny. These results show that t-AG implantations are capable of inducing masculinization of female sexual characteristics. The procedure of three implantations with 3 t-AGs at stage 6 is enough to transform the sex from a genetic female into a functional male. If t-AGs are used to implant instead of fresh AGs, we can detect the effects induced by newly formed AGs of recipient females, not by implanted donor's AGs. The present method may be useful for examining the regulatory mechanism of sex differentiation of female A. vulgare. PMID:9707482

    Full Text Available This study was conducted to evaluate the antifungal activities of cinnamon (Cinnamomum zeylanicum and oregano (Origanum vulgare L. essential oils against Aspergillus flavus in culture media and tomato paste. The chemical compositions of the essential oils were determined by Gas Chromatography-Mass Spectroscopy (GC-MS. Trans- cinnamaldehyde was found to be the main constituent of Cinnamomum zeylanicum essential oil (CZEO, followed by methyl eugenol, δ- cadinene and γ- cadinene. The major components of Origanum vulgare L. essential oil (OVEO were limonene, caryophyllene oxide, α-ionone, germacrene– D, γ- terpinene, β- pinene and terpinene-4-ol. For evaluating antifungal activities of CZEO and OVEO, A. flavus PTCC: 5006, was inoculated in Sabouraud Dextrose Broth (SDB and tomato paste, then 0, 50, 100, 200, 300, 400, 500 and 600 ppm of essential oils were added to each sample and incubated at 25±0.5oC for 30 and 60 days, respectively. The antifungal activity was measured by Agar Dilution method. The EOs at all tested concentrations had inhibitory effect against A. flavus growth. 200 ppm of CZEO and 500 ppm of OVEO completely inhibited A. flavus growth in culture media, while in tomato paste 300 ppm of CZEO and 200 ppm of OVEO had the same effect. Test panel evaluations were carried out in tomato ketchup base and samples with 100 and 200 ppm CZEO were accepted by panelists. The results may suggest the potential replacement of antifungal chemicals by CZEO as natural inhibitor to control A. flavus growth in tomato paste.

    Full Text Available One of the greatest efforts of modern science has been the symbolic identity and the economy of concepts in the language use at the time of classifying objects. If so, on the one hand, the common names are refused to fulfill the classification objectives. But, on the other hand, the symbolic meanings and functions which are rooted to the popular speech will be thrown over. Names are keys of a sign system or of a determined cosmovision. Thus the study object of this paper is the common orchid names taking into account mainly the naming sources and motivation in order to verify and establish criteria that solve the problem of this part of the Spanish in Cuba.

    In this study we investigated a synergistic effect between the essential oils Origanum vulgare, Pelargonium graveolens and Melaleuca alternifolia and the antifungal compound Nystatin. Nystatin is considered a drug of choice in the treatment of fungal infections, but it can cause some considerable problems through its side effects, such as renal damage. Finding a new product that can reduce the Nystatin dose via combination is very important. Our findings showed an experimental occurrence of a synergistic interaction between two of these essential oils and Nystatin. The essential oil O. vulgare appeared to be the most effective, inhibiting all the Candida species evaluated in this study. Some combinations of Nystatin and P. graveolens essential oil did not have any synergistic interactions for some of the strains considered. Associations of Nystatin with M. alternifolia essential oil had only an additive effect.

    This study investigated the in vivo antimicrobial activity of the essential oils of Origanum vulgare and Mentha piperita both singly, associated and in combination with immunotherapy to treat experimental pythiosis. The disease was reproduced in 18 rabbits divided into six groups (n=3): group 1, control; group 2, treated with essential oil of Mentha piperita; group 3, treated with essential oil of Origanum vulgare; group 4, treated with commercial immunotherapic; group 5, treated with a association of oils of M. piperita and O. vulgare and group 6, treated with a combination of both oils plus immunotherapy. Essential oils were added in a topical cream base formula, and lesions were treated daily for 45 days. The animals in groups 4 and 6 received a dose of immunotherapeutic agent every 14 days. The results revealed that the evolution of lesions in groups 5 and 6 did not differ from one another but differed from the other groups. The lesions of group 5 increased 3.16 times every measurement, while those of group 6 increased 1.83 times, indicating that the smallest growth of the lesions occurred when the combination of therapies were used. A rabbit from group 5 showed clinical cure at day 20 of treatment. This research is the pioneer in the treatment of experimental pythiosis using essential oils from medicinal plants and a combination of therapies. This study demonstrated that the use of essential oils can be a viable alternative treatment to cutaneous pythiosis, particularly when used in association or combination with immunotherapy.

    Full Text Available Heavy metals and other toxic elements in the environment, mainly located in soil and groundwater, have a significant effect on plant and its productivity that has a huge attention in recent years. Accumulation of heavy metals in soil cause toxicity to plants, and contaminate the food chain. The industrial areas, as well as developing countries have been contaminated with high concentration of heavy metals. Main sources of contamination are mining and other industrial processes, as well as military and or lanfills, sludge dumps or waste disposal sites. The heavy metals are very dangerous to environment and pose serious danger to public health by entering throught the food chain or into drinking water. Phytoextraction is one way how to remove the contaminants from soil by plants. Phytoextraction of heavy metals is a technology that has been studied for several years. It is more ecological and cheaper way how to clean our environment.Several plant species are known becauce they hyperaccumulate a high contents of metals from the soil. The accumulators are mainly herbaceous species, crops and nowadays angiosperm trees with a high growth such as poplars or willows.

    Hydroponic experiments were conducted in a growth chamber and changes in the hydraulic conductivity of sorghum (Sorghum vulgare Pers.) roots (Lpr) at the three-leaf stage were measured using the pressure chamber method. Water deficiency was imposed with polyethylene glycol (PEG) 6000 and the phosphorus (P) levels were controlled by complete Hoagland solution with and without P nutrient. The objective of this study was to investigate the effect of P nutrition on root Lpr under water deficiency. The results showed that the Lpr in P deficiency treatments decreased markedly, but the Lpr recovered to the same value as that of control when sufficient P was supplied for 4-24 h. Water deficiency decreased Lpr, but the hydraulic conductivity of the roots with sufficient P supply was still higher than that of plants without P supply. When resuming water supply, the Lpr of the water-deficient plants under P supply recovered faster than that of plants without P supply, which indicates that plants with sufficient P nutrient are more drought tolerant and have a greater ability to recover after drought. The treatment of HgCl2 indicated that P nutrient could regulate the Lpr by affecting the activity and the expression levels of aquaporins.

    Plant essential oils (EOs) can potentially replace synthetic fungicides in the management of postharvest fruit and vegetable diseases. The aim of this study was to evaluate in vitro and in vivo effectiveness of thymol, carvacrol, linalool, and trans-caryophyllene, single constituents of the EO of Origanum vulgare L. ssp. hirtum against Monilinia laxa, M. fructigena, and M. fructicola, which are important phytopathogens and causal agents of brown rot of pome and stone fruits in pre- and postharvest. Moreover, the possible phytotoxic activity of these constituents was assessed and their minimum inhibitory concentration (MIC) was determined. In vitro experiment indicated that thymol and carvacrol possess the highest antifungal activity. Results of in vivo trials confirmed the strong efficacy of thymol and carvacrol against brown rot of peach fruits. The thymol MIC resulted to be 0.16 μg/μL against M. laxa and M. fructigena and 0.12 μg/μL against M. fructicola, whereas for carvacrol they were 0.02 μg/μL against the first two Monilinia species and 0.03 μg/μL against the third. Results of this study indicated that thymol and carvacrol could be used after suitable formulation for controlling postharvest fruit diseases caused by the three studied Monilinia species.

    The aim of this work was to study the antimicrobial activity of essential oils obtained from Thymus vulgaris (thyme) and Origanum vulgare (oregano) on phytopathogenic Pseudomonas species isolated from soybean. Strains with characteristics of P. syringae were isolated from leaves of soybean plants with blight symptoms. Ten of these could be identified in Group Ia of LOPAT as P. syringae. Six of these were confirmed as P. syringae using 16S rRNA, indicating the presence of these phytopathogenic bacteria in east and central Argentina. All the phytopathogenic bacteria were re-isolated and identified from the infected plants. MIC values for thyme were 11.5 and 5.7 mg·ml(-1) on P. syringae strains, while oregano showed variability in the inhibitory activity. Both essential oils inhibited all P. syringae strains, with better inhibitory activity than the antibiotic streptomycin. The oils were not bactericidal for all pseudomonads. Both oils contained high carvacrol (29.5% and 19.7%, respectively) and low thymol (1.5%). Natural products obtained from aromatic plants represent potential sources of molecules with biological activity that could be used as new alternatives for the treatment of phytopathogenic bacteria infections.

    Consumers' concerns about the environment and health have led to the development of new food packaging materials avoiding petroleum-based matrices and synthetic additives. The present study has developed polylactic acid (PLA) films containing different concentrations of essential oil from Origanum vulgare L. virens (OEO). The effectiveness of this new active packaging was checked for use in ready-to-eat salads. A plasticising effect was observed when OEO was incorporated in PLA films. The rest of the mechanical and physical properties of developed films did not show much change when OEO was included in the film. An antioxidant effect was recorded only for films containing the highest percentages of the active agent (5% and 10%). In addition, films exhibited in vitro antibacterial activity against Staphylococcus aureus, Yersinia enterocolitica, Listeria monocytogenes, Enterococcus faecalis and Staphylococcus carnosus. Moreover, in ready-to-eat salads, antimicrobial activity was only observed against yeast and moulds, where 5% and 10% of OEO was the most effective. PMID:27455176

    2005-01-01

    106 accessions of Tibetan wild barley, including 50 accessions of the two-rowed wild barley Hordeum vulgare ssp. spontaneum(HS), 27 accessions of the six-rowed bottle-shaped wild barley H. lagunculiforme(HL) and 29 accessions of the six-rowed wild barley H. agriocrithon(HA) that separately represent different agrigeographical regions of Tibet, were used to study the genetic diversity and genetic differentiation using SSR markers selected from seven barley linkage groups. 229 allelic variants were identified with an average of 7.6 alleles/locus. The average of total number of alleles per locus in HA(6.4) is much higher than that in HS(3.9) and HL(3.4). The genetic diversity and its standard deviation among the three subspecies were in the order of HS>HL>HA. Very significant genetic differentiation was observed among the three subspecies of wild barley. Comparisons of the results from this and previous studies showed a strong Oriental-Occidental differentiation of barley, and that Shannan region of Tibet might be the center of origin of the Tibetan two-rowed wild barley, thus supporting not only the hypothesis of a mono-phyletic origin of cultivated barley but also the proposition that the Tibetan two-rowed wild barley as ultimate progenitor of Chinese cultivated barley.

    Full Text Available Multidrug-resistant Salmonella enterica isolates from human outbreaks or from poultry origin were investigated for their ability to develop direct-tolerance or cross-tolerance to sodium chloride (NaCl, potassium chloride (KCl, lactic acid (LA, acetic acid (AA and ciprofloxacin (CIP after habituation in subinhibitory amounts (½ of the minimum inhibitory concentration - ½ MIC and ¼ of the minimum inhibitory concentration - ¼ MIC of Origanum vulgare L. essential oil (OVEO at different time intervals. The habituation of S. enterica to OVEO did not induce direct-tolerance or cross-tolerance in the tested strains, as assessed by the modulation of minimum inhibitory concentration (MIC values. However, cells habituated to OVEO maintained or increased susceptibility to the tested antimicrobials agents, with up to four-fold double dilution decrease from previously determined MIC values. This study reports for the first time the non-inductive effect of OVEO on the acquisition of direct-tolerance or cross-tolerance in multidrug-resistant S. enterica strains to antimicrobial agents that are largely used in food preservation, as well as to CIP, the therapeutic drug of salmonellosis.

    Three different isoforms of invertases have been detected in the developing internodes of barley (Hordeum vulgare). Based on substrate specificities, the isoforms have been identified to be invertases (beta-fructosidases EC 3.2.1.26). The soluble (cytosolic) invertase isoform can be purified to apparent homogeneity by diethylaminoethyl cellulose, Concanavalin-A Sepharose, organo-mercurial Sepharose, and Sephacryl S-300 chromatography. A bound (cell wall) invertase isoform can be released by 1 molar salt and purified further by the same procedures as above except omitting the organo-mercurial Sepharose affinity chromatography step. A third isoform of invertase, which is apparently tightly associated with the cell wall, cannot be isolated yet. The soluble and bound invertase isoforms were purified by factors of 60- and 7-fold, respectively. The native enzymes have an apparent molecular weight of 120 kilodaltons as estimated by gel filtration. They have been identified to be dimers under denaturing and nondenaturing conditions. The soluble enzyme has a pH optimum of 5.5, Km of 12 millimolar, and a Vmax of 80 micromole per minute per milligram of protein compared with cell wall isozyme which has a pH optimum of 4.5, Km of millimolar, and a Vmax of 9 micromole per minute per milligram of protein.

    In water-limited areas of Tunisia, more than 30% of subsurface water used for irrigation is saline water, leading to a long-term salinization and degradation processes. To prevent the problems and to minimize the negative impact of using saline water, selection of proper germplasm as well as integrated soil and water management are essential. Understanding the diversity for salt tolerance in barley (Hordeum vulgare L.) genotypes will facilitate their use in genetic improvement. Our objectives were to evaluate, in green, house-salt tolerance for 14 barley cultivars under three different salinity levels: (tap water with an Ec = 0.73 dSm(-1), tap water with 102 mM of NaCl, Ec = 10.76 dSm(-1) and tap water with 151 mM of NaCl, Ec = 15.38 dSm(-1)), and quantify genetic variation based on salt tolerance index, morphological traits, molecular and factorial analysis of correspondence (FAC). The study was conducted in a randomized complete block design arranged as a split plot. The results indicate a great genetic variability to salt tolerance among used barley genotypes. Consequently, it is possible to identify superior cultivars, and evaluate the genotypic performance under salinities conditions. In addition, results obtained were confirmed by clustering made by SSR tool on the base of DNA analysis, which is compatible with the arrangement obtained with statistical method. PMID:20626765

    1. The objective of the present study was to investigate the mechanism of the relaxant activity of marrubenol, a diterpenoid extracted from Marrubium vulgare. In rat aorta, marrubenol was a more potent inhibitor of the contraction evoked by 100 mM KCl (IC50: 11.8+/-0.3 microM, maximum relaxation: 93+/-0.6%) than of the contraction evoked by noradrenaline (maximum relaxation: 30+/-1.5%). 2. In fura-2-loaded aorta, marrubenol simultaneously inhibited the Ca2+ signal and the contraction evoked by 100 mM KCl, and decreased the quenching rate of fura-2 fluorescence by Mn2+. 3. Patch-clamp data obtained in aortic smooth muscle cells (A7r5) indicated that marrubenol inhibited Ba2+ inward current in a voltage-dependent manner (KD: 8+/-2 and 40+/-6 microM at holding potentials of -50 and -100 mV, respectively). 4. These results showed that marrubenol inhibits smooth muscle contraction by blocking L-type calcium channels. PMID:14597602

Minimum Inhibitory Concentration (MIC and Minimum Bactericidal Concentration (MBC of the oil was 0.6 and 1.25 µL.mL-1, respectively. Lactic acid showed MIC and MBC of 2.5 and 5µL.mL-1, respectively. FIC indices of the combined application of the oil and lactic acid were 0.5 showing a synergic interaction. The essential oil and lactic acid showed similar (p>0.05 anti-S. aureus effect in meat broth over 96 h of exposure. Treatment with essential oil or lactic acid presented a smaller anti-staphylococcal effect in meat in comparison to meat broth. No significant difference (p>0.05 was found for the microbial counts in meat treated with each antimicrobial alone or in mixture. These results could arise as an interesting approach for the improvement of food preservation using more natural procedures, considering the current demand of consumer and sensory quality of foods.

    1. The objective of the present study was to investigate the mechanism of the relaxant activity of marrubenol, a diterpenoid extracted from Marrubium vulgare. In rat aorta, marrubenol was a more potent inhibitor of the contraction evoked by 100 mM KCl (IC50: 11.8+/-0.3 microM, maximum relaxation: 93+/-0.6%) than of the contraction evoked by noradrenaline (maximum relaxation: 30+/-1.5%). 2. In fura-2-loaded aorta, marrubenol simultaneously inhibited the Ca2+ signal and the contraction evoked by 100 mM KCl, and decreased the quenching rate of fura-2 fluorescence by Mn2+. 3. Patch-clamp data obtained in aortic smooth muscle cells (A7r5) indicated that marrubenol inhibited Ba2+ inward current in a voltage-dependent manner (KD: 8+/-2 and 40+/-6 microM at holding potentials of -50 and -100 mV, respectively). 4. These results showed that marrubenol inhibits smooth muscle contraction by blocking L-type calcium channels.

    The tucuma (Astrocaryum vulgare Mart.) is a native fruit of Amazonia, occurring mainly in the state of Para, but also found in the Brazilian northeast states and in the Brazilian central-western states. The tucuma is considered an excellent source of carotenoids with a very high concentration of {beta}-carotene, which is a precursor of vitamin A. In addition to carotenoids it is an important source of vitamin B2 (riboflavin) in fruits. This study aimed to analyze the effects of gamma radiation on the nutritional value of tucuma. The fruits were irradiated at doses of 0.5, 1.0 and 2.0 kGy irradiator with a source of cesium 137. The carotenoids were determined by spectrophotometry. The analysis of {alpha} and {beta}-carotene, thiamine, riboflavin were carried out by high performance liquid chromatography (HPLC). The {beta}-carotene accounts for 80% of total carotenoids in tucuma, and with a dose of 2 kGy, it showed the highest reduction of {beta}-carotene, about 7.5% in relation to the control. The tucuma fruit showed high levels of riboflavin from 0.183 to 0.222 {mu}g 100 g{sup -1}, and maintained stability after the gamma radiation process. However, it had low levels of thiamine from 0.050 to 0.033 {mu}g 100 g{sup -1}, and irradiated at a dose of 2 kGy showed significant reductions of thiamine, about 34% in relation to the control.

    Full Text Available The studies of Armadillidium vulgare as pest are virtually null worldwide. However under no-tillage systems this species has found an adequate environment for its development and it has become an important pest in some crops in Argentina. It has been shown that the composition of vegetables affects the isopods biology. Our hypothesis was that soybean leaf litter has high nutritive value which allows A. vulgare to grow faster, survive longer, and have higher fecundity favoring the population increase and turning it into a crop pest. Growth and survivorship of juveniles and adults, egg incubation period, offspring number per female and offspring mean body weight were determined in individuals fed with leaf litter of soybean, sunflower, wheat and pasture. The growth rate coefficient, k, in juveniles was higher for soybean, intermediate for pasture and lower for sunflower. Adult growth was faster under the soybean diet. Survivorship under soybean and pasture was longer than under sunflower and wheat in both juveniles and adults. The reproductive parameters were similar in all diets, food did not generate any change in the reproductive aspects of A. vulgare. Results of the present study represent a source of information about the A. vulgare biology under different diets of agricultural origin to establish the basis for Integrated Management of this species as pest. Under soybean litter provision A. vulgare found the best conditions for faster growth, longer survival and relatively higher fecundity. In fields with soybean as preceding crop or in systems with high frequency of soybean in the crop rotation a more abundant population of A. vulgare would be found as well as with larger individuals which could cause more damage to the following crop in the rotation.Los estudios sobre Armadillidium vulgare como plaga son virtualmente nulos a nivel mundial.

    Full Text Available The aim of this study was to assess the effects of a fungicide (copper hydroxide with 50% metallic copper (Co and of an insecticide (bifenthrin 100 g/l (B on spore germination and gametophyte development in the fern species Athyrium filix-femina (L. Schott. and Polypodium vulgare L. The experimental variants were: V1Co: 0.1 gr fungicide/100 ml Knop solution, V2Co: 0.2 gr fungicide/100 ml Knop solution, V3Co: 3 gr fungicide/100 ml Knop solution, V1B: 0.01 ml insecticide/100 ml Knop solution, V2B: 0.02 ml insecticide/100 ml Knop solution, V3B: 0.04 ml insecticide/100 ml Knop solution and Control (C: 100 ml Knop solution. Co inhibited spore germination in all the experimental variants tested on the species Athyrium filix-femina. In the V3Co variant, after 24 days, no spore germinated. B also inhibited spore germination in all the experimental variants. In Polypodium vulgare, Co significantly inhibited spore germination. In the experimental variants containing B, only in the V3B variant the germination is significantly inhibited. Calculations showed a significant negative correlation between the germination percentage and the concentration of pesticides. The fungicide also affected gametophyte differentiation, which happened much more slowly in both species. The rhizoids of the gametophytes of Polypodium vulgare showed modifications in their differentiation and morphology that could also be related to alterations in their biochemical composition. The experimental variants with the highest concentration of insecticide resulted in the differentiation of abnormal gametophytes growing in a tridimensional cellular mass with callus morphology. The responses of plants to the induced stress produced during the testing period may be used as biomarkers of environmental pollution caused by pesticides.

    Full Text Available Background and purpose: During recent years, nitric oxide (NO has been considered as a molecule involved in migraine headaches. This free radical involves in initiation of migraine headaches via NO/cGMP signaling pathway and vascular relaxation specially big intracranial arteries. Therefore, we studied the effects of aqueous extract of Origanum vulgare and Melilotus officinalis prescribed in migraine treatment in traditional & modern medicine, on NO level in cultured endothelial cells.Materials and Methods: Each crude herb (25g was mixed with 200 ml distilled water. End extract obtained after filtering and drying. Endothelial cells propagated in DMEM medium containing 10% FCS and 1-2% penicillin-streptomycin. The nitrite concentration was measured as an indicator of nitric oxide production according to the Griess reaction and with ELISA in 540 nm.Results: Concentrations of 100, 200 and 400 g/ml of Origanum vulgare, reduced NO levels compared with control to 13.1 % (p<0.05, 25.8% (p<0.01 and 33.9% (p<0.001 respectively. However, despite our expectation melilotus officinalis increased NO level. The concentrations of 100, 200 and 400 g/ml of the herb, increased NO levels to 12.7 (p<0.05, 36.5% (p<0.001 & 72.9% (p<0.001 respectively.Conclusion: We concluded that aqueous extract of Origanum vulgare probably decreases migraine headaches by reducing NO and aqueous extract of Melilotus officinalis does not act through this mechanism.

    This study investigated the in vivo antimicrobial activity of the essential oils of Origanum vulgare and Mentha piperita both singly, associated and in combination with immunotherapy to treat experimental pythiosis. The disease was reproduced in 18 rabbits divided into six groups (n=3): group 1, control; group 2, treated with essential oil of Mentha piperita; group 3, treated with essential oil of Origanum vulgare; group 4, treated with commercial immunotherapic; group 5, treated with a association of oils of M. piperita and O. vulgare and group 6, treated with a combination of both oils plus immunotherapy. Essential oils were added in a topical cream base formula, and lesions were treated daily for 45 days. The animals in groups 4 and 6 received a dose of immunotherapeutic agent every 14 days. The results revealed that the evolution of lesions in groups 5 and 6 did not differ from one another but differed from the other groups. The lesions of group 5 increased 3.16 times every measurement, while those of group 6 increased 1.83 times, indicating that the smallest growth of the lesions occurred when the combination of therapies were used. A rabbit from group 5 showed clinical cure at day 20 of treatment. This research is the pioneer in the treatment of experimental pythiosis using essential oils from medicinal plants and a combination of therapies. This study demonstrated that the use of essential oils can be a viable alternative treatment to cutaneous pythiosis, particularly when used in association or combination with immunotherapy.

    Mosquito-borne diseases represent a deadly threat for millions of people worldwide. However, the use of synthetic insecticides to control Culicidae may lead to resistance, high operational costs and adverse non-target effects. Nowadays, plant-borne mosquitocides may serve as suitable alternative in the fight against mosquito vectors. In this study, the mosquito larvicidal activity of Origanum vulgare (Lamiaceae) leaf essential oil (EO) and its major chemical constituents was evaluated against the malaria vectors Anopheles stephensi and An. subpictus, the filariasis vector Culex quinquefasciatus and the Japanese encephalitis vector Cx. tritaeniorhynchus. The chemical composition of the EO was analyzed by gas chromatography-mass spectroscopy. GC-MS revealed that the essential oil of O. vulgare contained 17 compounds. The major chemical components were carvacrol (38.30%) and terpinen-4-ol (28.70%). EO had a significant toxic effect against early third-stage larvae of An. stephensi, An. subpictus, Cx. quinquefasciatus and Cx. tritaeniorhynchus, with LC50 values of 67.00, 74.14, 80.35 and 84.93 μg/ml. The two major constituents extracted from the O. vulgare EO were tested individually for acute toxicity against larvae of the four mosquito vectors. Carvacrol and terpinen-4-ol appeared to be most effective against An. stephensi (LC50=21.15 and 43.27 μg/ml, respectively) followed by An. subpictus (LC50=24.06 and 47.73 μg/ml), Cx. quinquefasciatus (LC50=26.08 and 52.19 μg/ml) and Cx. tritaeniorhynchus (LC50=27.95 and 54.87 μg/ml). Overall, this research adds knowledge to develop newer and safer natural larvicides against malaria, filariasis and Japanese encephalitis mosquito vectors. PMID:26850541

Fibrogenesis caused by hepatic stellate cells is inhibited by PPARγ whose ligands are clinically used for the treatment of diabetes. Plant extracts of Marrubium vulgare L., were screened for activity to inhibit fibrosis in the hepatic stellate cell line HSC-T6 using Oil Red-O staining, which detects lipids that typically accumulate in quiescent hepatic stellate cells. A methanol extract with activity to stimulate accumulation of lipids was obtained. This extract was found to have PPARγ agonist activity using a luciferase reporter assay. After purification using several chromatographic methods, 6-ODA, a fatty acid with a triple bond, was identified as a candidate of PPARγ agonist. Synthesized 6-ODA and its derivative 9-octadecynoic acid (9-ODA), which both have a triple bond but in different positions, activated PPARγ in a luciferase reporter assay and increased lipid accumulation in 3T3-L1 adipocytes in a PPARγ-dependent manner. There is little information about the biological activity of fatty acids with a triple bond, and to our knowledge, this is the first report that 6-ODA and 9-ODA function as PPARγ agonists

    Full Text Available Abstract Background Among the cereal crops, barley is the species with the greatest adaptability to a wide range of environments. To determine the level and structure of genetic diversity in barley (Hordeum vulgare L. landraces from the central highlands of Ethiopia, we have examined the molecular variation at seven nuclear microsatellite loci. Results A total of 106 landrace populations were sampled in the two growing seasons (Meher and Belg; the long and short rainy seasons, respectively, across three districts (Ankober, Mojanawadera and Tarmaber, and within each district along an altitudinal gradient (from 1,798 to 3,324 m a.s.l. Overall, although significant, the divergence (e.g. FST is very low between seasons and geographical districts, while it is high between different classes of altitude. Selection for adaptation to different altitudes appears to be the main factor that has determined the observed clinal variation, along with population-size effects. Conclusions Our data show that barley landraces from Ethiopia are constituted by highly variable local populations (farmer's fields that have large within-population diversity. These landraces are also shown to be locally adapted, with the major driving force that has shaped their population structure being consistent with selection for adaptation along an altitudinal gradient. Overall, our study highlights the potential of such landraces as a source of useful alleles. Furthermore, these landraces also represent an ideal system to study the processes of adaptation and for the identification of genes and genomic regions that have adaptive roles in crop species.

    Full Text Available This paper estimates the reference Evapotranspiration (ET0 and Water requirements of barley (Hordeum vulgare L. in Ksar-Chellala region, Algeria, for one dry year by using CROPWAT software. Determination of Evapotranspiration ( ET is important in application such as irrigation design, irrigation scheduling, water resource management, hydrology and cropping systems modeling. Estimation of crop water requirements of barley ( CWR b respected the methodology adopted by the service of development and management service of FAO, based on the use of software CROPWAT 8.0. The total water requirements for barley depend on a variety of target yields and crops management. The period of climatic data used is 23 years (1990-2012, the average rain in this period is 254 mm. The total rain of the dry year is 190 mm. The results of this study show, during the vegetative cycle of barley which is 6 months, the calculation of ET 0 is 453 mm, the potential water which was used by the crop barley is estimated at 281.4 mm, the efficiency of rainfall is 69 mm and a total water requirements of barley ( CWR b equals to 211 mm, this amount distributed on three months coincided with important stages of development in barley. The supplementary irrigation in these conditions with optimal contents equals water requirements estimated by CROPWAT software that increases significantly grain yield of barely. Consequently, the gross irrigation water requirements ( GIWR of 1250000 ha which project to grow barley in the Algerian steppes regions are estimated at 3.77 billion and this for a dry year and a irrigation efficiency of 70%.

    The implications of metal nanoparticles (MeNPs) are still unknown for many food crops. The purpose of this study was to evaluate the effects of cerium oxide (nCeO2) and titanium oxide (nTiO2) nanoparticles in soil at 0, 500 and 1000 mg·kg−1 on the nutritional parameters of barley (Hordeum vulgare L.) kernels. Mineral nutrients, amylose, β-glucans, amino acid and crude protein (CP) concentrations were measured in kernels. Whole flour samples were analyzed by ICP-AES/MS, HPLC and Elemental CHNS Analyzer. Results showed that Ce and Ti accumulation under MeNPs treatments did not differ from the control treatment. However, nCeO2 and nTiO2 had an impact on composition and nutritional quality of barley kernels in contrasting ways. Both MeNPs left β-glucans unaffected but reduced amylose content by approximately 21%. Most amino acids and CP increased. Among amino acids, lysine followed by proline saw the largest increase (51% and 37%, respectively). Potassium and S were both negatively impacted by MeNPs, while B was only affected by 500 mg nCeO2·kg−1. On the contrary Zn and Mn concentrations were improved by 500 mg nTiO2·kg−1, and Ca by both nTiO2 treatments. Generally, our findings demonstrated that kernels are negatively affected by nCeO2 while nTiO2 can potentially have beneficial effects. However, both MeNPs have the potential to negatively impact malt and feed production. PMID:27294945

    Type 1 diabetes (T1D) is an autoimmune disease that develops as a consequence of pancreatic β-cell death induced by proinflammatory mediators. Because Origanum vulgare L. ssp. hirtum (Greek oregano) contains antiinflammatory molecules, we hypothesized that it might be beneficial for the treatment of T1D. An ethyl acetate extract of oregano (EAO) was prepared from the leaves by a polar extraction method. Phytochemical composition was determined by liquid chromatography-UV diode array coupled to ion-trap mass spectrometry with electrospray ionization interface (LC/DAD/ESI-MS(n) ). In vitro immunomodulatory effect of EAO was estimated by measuring proliferation (MTT) or cytokine secretion (ELISA) from immune cells. Diabetes was induced by multiple low doses of streptozotocin (MLDS) in male C57BL/6 mice and EAO was administered intraperitoneally for 10 d. Determination of cellular composition (flow cytometry) and cytokine production (ELISA) was performed on 12th d after diabetes induction. EAO suppressed the function of both macrophages and lymphocytes in vitro. In vivo, EAO treatment significantly preserved pancreatic islets and reduced diabetes incidence in MLDS-challenged mice. Besides down-modulatory effect on macrophages, EAO reduced the number of total CD4(+) and activated CD4(+) CD25(+) T cells. Furthermore, EAO affected the number of T helper 1 (Th1) and T helper 17 (Th17) cells through downregulation of their key transcription factors T-bet and RORγT. Because EAO treatment protects mice from development of hyperglycemia by reducing proinflammatory macrophage/Th1/Th17 response, this plant extract could represent a basis for future diabetes therapy.

    A software tool was developed for the identification of simple sequence repeats (SSRs) in a barley ( Hordeum vulgare L.) EST (expressed sequence tag) database comprising 24,595 sequences. In total, 1,856 SSR-containing sequences were identified. Trimeric SSR repeat motifs appeared to be the most abundant type. A subset of 311 primer pairs flanking SSR loci have been used for screening polymorphisms among six barley cultivars, being parents of three mapping populations. As a result, 76 EST-derived SSR-markers were integrated into a barley genetic consensus map. A correlation between polymorphism and the number of repeats was observed for SSRs built of dimeric up to tetrameric units. 3'-ESTs yielded a higher portion of polymorphic SSRs (64%) than 5'-ESTs did. The estimated PIC (polymorphic information content) value was 0.45 +/- 0.03. Approximately 80% of the SSR-markers amplified DNA fragments in Hordeum bulbosum, followed by rye, wheat (both about 60%) and rice (40%). A subset of 38 EST-derived SSR-markers comprising 114 alleles were used to investigate genetic diversity among 54 barley cultivars. In accordance with a previous, RFLP-based, study, spring and winter cultivars, as well as two- and six-rowed barleys, formed separate clades upon PCoA analysis. The results show that: (1) with the software tool developed, EST databases can be efficiently exploited for the development of cDNA-SSRs, (2) EST-derived SSRs are significantly less polymorphic than those derived from genomic regions, (3) a considerable portion of the developed SSRs can be transferred to related species, and (4) compared to RFLP-markers, cDNA-SSRs yield similar patterns of genetic diversity.

    Full Text Available The implications of metal nanoparticles (MeNPs are still unknown for many food crops. The purpose of this study was to evaluate the effects of cerium oxide (nCeO2 and titanium oxide (nTiO2 nanoparticles in soil at 0, 500 and 1000 mg·kg−1 on the nutritional parameters of barley (Hordeum vulgare L. kernels. Mineral nutrients, amylose, β-glucans, amino acid and crude protein (CP concentrations were measured in kernels. Whole flour samples were analyzed by ICP-AES/MS, HPLC and Elemental CHNS Analyzer. Results showed that Ce and Ti accumulation under MeNPs treatments did not differ from the control treatment. However, nCeO2 and nTiO2 had an impact on composition and nutritional quality of barley kernels in contrasting ways. Both MeNPs left β-glucans unaffected but reduced amylose content by approximately 21%. Most amino acids and CP increased. Among amino acids, lysine followed by proline saw the largest increase (51% and 37%, respectively. Potassium and S were both negatively impacted by MeNPs, while B was only affected by 500 mg nCeO2·kg−1. On the contrary Zn and Mn concentrations were improved by 500 mg nTiO2·kg−1, and Ca by both nTiO2 treatments. Generally, our findings demonstrated that kernels are negatively affected by nCeO2 while nTiO2 can potentially have beneficial effects. However, both MeNPs have the potential to negatively impact malt and feed production.

    Hordeum vulgare plants were stressed with Hg, Cd and As and their phytotoxicity was evaluated in terms of growth inhibition and total metal uptake by the plant. The synthesised phytochelatins ((γ-Glu-Cys)n-Gly, n=2-5; PCs) were determined by HPLC with amperometric detection at a glassy carbon electrode. The results indicate that H. vulgare is a good phytostabilisation plant due to its capacity to accumulate heavy metals in roots. Cd and Hg are the most uptake toxic elements, being Cd the most potent inducer of PCs. The data obtained on the different PCs and related peptides induced by each heavy metal were used to perform a Principal Component Analysis (PCA) of the results as a function of the contaminating toxic element or its concentration level. The nature of the stressor element could be predicted from the pattern of PCs and related peptides identified by PCA. PCs were the most strongly induced peptides under Cd and Hg stress, whereas As only tended to synthesise small thiols such as glutathione and γ-glutamylcysteine, both precursors of PCs synthesis. This finding indicates that PCs are induced at different rates depending on the metal stressor used.

    6-Octadecynoic acid (6-ODA), a fatty acid with a triple bond, was identified in the methanol extract of Marrubium vulgare L. as an agonist of peroxisome proliferator-activated receptor γ (PPARγ). Fibrogenesis caused by hepatic stellate cells is inhibited by PPARγ whose ligands are clinically used for the treatment of diabetes. Plant extracts of Marrubium vulgare L., were screened for activity to inhibit fibrosis in the hepatic stellate cell line HSC-T6 using Oil Red-O staining, which detects lipids that typically accumulate in quiescent hepatic stellate cells. A methanol extract with activity to stimulate accumulation of lipids was obtained. This extract was found to have PPARγ agonist activity using a luciferase reporter assay. After purification using several chromatographic methods, 6-ODA, a fatty acid with a triple bond, was identified as a candidate of PPARγ agonist. Synthesized 6-ODA and its derivative 9-octadecynoic acid (9-ODA), which both have a triple bond but in different positions, activated PPARγ in a luciferase reporter assay and increased lipid accumulation in 3T3-L1 adipocytes in a PPARγ-dependent manner. There is little information about the biological activity of fatty acids with a triple bond, and to our knowledge, this is the first report that 6-ODA and 9-ODA function as PPARγ agonists.

    Antimicrobial peptides (AMPs) are key components of innate immunity and are widespread in nature, from bacteria to vertebrate animals. In crustaceans, there are currently 15 distinct AMP families published so far in the literature, mainly isolated from members of the Decapoda order. Up to now, armadillidin is the sole non-decapod AMP isolated from the haemocytes of Armadillidium vulgare, a crustacean isopod. Its first description demonstrated that armadillidin is a linear glycine-rich (47%) cationic peptide with an antimicrobial activity directed toward Bacillus megaterium. In the present work, we report identification of armadillidin Q, a variant of armadillidin H (earlier known as armadillidin), from crude haemocyte extracts of A. vulgare using LC-MS approach. We demonstrated that both armadillidins displayed broad spectrum antimicrobial activity against several Gram-positive and Gram-negative bacteria, fungi, but were totally inactive against yeasts. Membrane permeabilization assays, only performed with armadillidin H, showed that the peptide is membrane active against bacterial and fungal strains leading to deep changes in cell morphology. This damaging activity visualized by electronic microscopy correlates with a rapid decrease of cell viability leading to highly blebbed cells. In contrast, armadillidin H does not reveal cytotoxicity toward human erythrocytes. Furthermore, no secondary structure could be defined in this study [by circular dichroism (CD) and nuclear magnetic resonance (NMR)] even in a membrane mimicking environment. Therefore, armadillidins represent interesting candidates to gain insight into the biology of glycine-rich AMPs.

    Background: Sporadic Alzheimer’s Disease (SAD) is caused by genetic risk factors, aging and oxidative stresses. The herbal extract of Rosa canina (R. canina), Tanacetum vulgare (T. vulgare) and Urtica dioica (U. dioica) has a beneficial role in aging, as an anti-inflammatory and anti-oxidative agent. In this study, the neuroprotective effects of this herbal extract in the rat model of SAD was investigated. Methods: The rats were divided into control, sham, model, herbal extract -treated and ethanol-treated groups. Drug interventions were started on the 21st day after modeling and each treatment group was given the drugs by intraperitoneal (I.P.) route for 21 days. The expression levels of the five important genes for pathogenesis of SAD including Syp, Psen1, Mapk3, Map2 and Tnf-α were measured by qPCR between the hippocampi of SAD model which were treated by this herbal extract and control groups. The Morris Water Maze was adapted to test spatial learning and memory ability of the rats. Results: Treatment of the rat model of SAD with herbal extract induced a significant change in expression of Syp (p=0.001) and Psen1 (p=0.029). In Morris Water Maze, significant changes in spatial learning seen in the rat model group were improved in herbal-treated group. Conclusion: This herbal extract could have anti-dementia properties and improve spatial learning and memory in SAD rat model. PMID:27563424

    Full Text Available In order to determine the performance of barley under drought stress conditions and screening quantitative indices of drought tolerance, twelve barley (Hordeum vulgare L. cultivars were tested in a split-plot arranged in a randomized complete blocks design with three replications under irrigated and post-anthesis water deficiency conditions. This study was carried out in the field research of campus of agriculture and natural resources, Razi university, Kermanshah state in the west of Iran during 2010-2011. The results showed that post anthesis water deficiency caused 22, 18.3, 5.9, 5.5 and 21.9 percent reduction in grain yield, biomass, thousand grain weight, number of grain per spike and number of spike per m2 in average respectively, but had no significant effect on harvest index. Mean comparisons showed that Nosrat cultivar with 838 g m-2 and Afzal cultivar with 392 g m-2, respectively had the highest and the lowest grain yield under non-stress condition. Under water stress environment Nosrat and Karoun cultivars with 696 and 656 g m-2 and also, Aras and Sahra cultivars with 322 and 327 g m-2, respectively had the highest and the lowest grain yield. The estimates of stress tolerance attributes indicated that the identification of drought-tolerant genotypes based on a single criterion was contradictory. For example, according to STI, GMP and MP cultivars Nosrat, Karoun and Sararud were the most, whereas Aras and Afzal cultivars the least relative tolerant genotypes. As to YI cultivars Nosrat, Karoun and Sararud were the most and Aras, Sahra and Afzal the least relative tolerant genotypes. According to YSI, SSPI, RDI and ATI indices selected the Sararud and Zarjo cultivars as the most relatively tolerant genotypes. DI selected the cultivars Sararud, Nosrat and Karoun as the best, while the cultivars Sahra, Aras and Reihan as the the worst relatively tolerant genotypes. Grain yield in stress condition was significantly and positively correlated

    Olive-mill wastewater (OMW) is a by-product effluent of olive oil extraction process that is produced in large amount in the Mediterranean region. OMW is believed to induce phytotoxic effect on organisms including seed germination and plant growth. The objective of this study was to evaluate the impact of untreated and treated OMW with different techniques on seed germination of barley (Hordeum vulgare L.). The following treatments were investigated: (1) tap water (control); (2) OMW treated by aerobic biological technology in a Jacto Reactor (JR); (3) OMW treated by solar fenton oxidation (SFO); (4) OMW treated by microfiltration followed by nanofiltration (MF+NF); (5) OMW treated by microfiltration followed by reverse osmosis (MF+RO) process; (6) diluted OMW with tap water (25 % OMW); (7) diluted OMW with tap water (50 % OMW); (8) diluted OMW with tap water (75 % OMW); and (9) untreated OMW (100 % OMW). A germination test was conducted in an incubator at temperature of 23 (∘)C. In each petri dish, a filter paper was mounted and ten seeds of barley were placed on the filter paper. Five milliliter of water were added to each petri dish. The seed germination was determined by counting the number of germinated seeds to calculate the percentage of germination (G %). Germination rate index (GRI), seed vigor index (SVI), and phytotoxicity index (PI) were also calculated. Then, the dry weights and lengths of the shoots and the roots of the germinated seeds were measured. The results show that 100, 75, and 50 %OMW were very phytotoxic and completely prohibited seed germination. However, phytotoxicity decreased significantly following treatments of OMW with all techniques investigated and by the 25 % OMW dilution, as results of removing the phenols and other phytotoxic organic compounds from the OMW or by diluting it. This was evidenced by relative enhancement of the dry weights and lengths of shoot and root as well as the G %, GRI, SVG, and PI. It was concluded that if

    Full Text Available ABSTRACT Rosmarinus officinalis L. (rosemary and Origanum vulgare L. (oregano are known to have antimicrobial properties, but studies on sporotrichosis are scarce. This study aimed to evaluate the anti-Sporothrix spp. activity of essential oils from commercial products and oils extracted from aerial parts of these plants and analyze their chemical constituents. S. schenckii complex and S. brasiliensis (n: 25 isolated from humans, cats, dogs, and environmental soil were tested through M27-A3 guidelines of CLSI with modification for phytotherapics. The essential oils of R. officinalis L. were similar for MIC50 and MFC50 ≤2.25mg/mL for extracted oil; and 4.5mg/mL and 9mg/mL, respectively, for commercial oil. Both products showed MIC90 of 18mg/mL and MFC90 of 36mg/mL. In O. vulgare L., the extracted oil had better activity with MIC50 and MFC50 ≤2.25mg/mL, and MIC90 and MFC90 of 4.5mg/mL, whereas the commercial oil showed MIC50 and MFC50 of 9mg/mL and MIC90 18mg/mL, respectively, and MFC90 of 36mg/mL. Through gas chromatography (CG/FID, thymol and α-terpinene were majority for extracted oil of O. vulgare L., and carvacrol and γ-terpinene made up the majority of the commercial oil. Both essential oils of R. officinalis L. showed 1,8-cineole and α-pinene as major. The fungal isolates were susceptible to all tested essential oils, including in itraconazole-resistant S. brasiliensis isolates. The extracted and commercial oils of the plants presented in vitro anti-Sporothrix spp. activity, and they are promising for treatment of sporotrichosis, including in cases refractory to itraconazole. More studies should be performed about toxicity and in vivo efficacy for its safe use.

    Three basic chitinases and one basic beta-1,3-glucanase were secreted into the medium when embryogenic cell suspensions of barley (Hordeum vulgare L.) cv. 'Igri' were cultured as undifferentiated aggregates in the presence of 2,4-D. The enzymes were purified by affinity and ion exchange...... chromatography. Two of the chitinases were identified as the previously described endochitinases T and C from barley grain. The third and novel chitinase, designated K, was the major basic chitinase in the medium constituting 4% of the soluble protein. Chitinase K was found to be a 33-kDa endochitinase with p......I at 8.7. Further analysis showed that this enzyme is also expressed in barley grain. The amino acid composition and five partial amino acid sequences covering 93 residues of chitinase K were determined.

    Plant Growth Promoting Bacteria (PGPB) are considered a promising approach to replace the conventional agricultural practices, since they have been shown to affect plant nutrient-acquisition processes by influencing nutrient availability in the rhizosphere and/or those biochemical processes determining the uptake at root level of nitrogen (N), phosphorus (P), and iron (Fe), that represent the major constraints for crop productivity worldwide. We have isolated novel bacterial strains from the rhizosphere of barley (Hordeum vulgare L.) and tomato (Solanum lycopersicon L.) plants, previously grown in hydroponic solution (either Fe deficient or Fe sufficient) and subsequently transferred onto an agricultural calcareous soil. PGPB have been identified by molecular tools and characterized for their capacity to produce siderophores and indole-3-acetic acid (IAA), and to solubilize phosphate. Selected bacterial isolates, showing contemporarily high levels of the three activities investigated, were finally tested for their capacity to induce Fe reduction in cucumber roots two isolates, from barley and tomato plants under Fe deficiency, significantly increased the root Fe-chelate reductase activity; interestingly, another isolate enhanced the reduction of Fe-chelate reductase activity in cucumber plant roots, although grown under Fe sufficiency.

    Full Text Available SGT1 is an evolutionarily conserved eukaryotic protein involved in many important cellular processes. In plants, SGT1 is involved in resistance to disease. In a low ionic strength environment, the SGT1 protein tends to form dimers. The protein consists of three structurally independent domains (the tetratricopeptide repeats domain (TPR, the CHORD- and SGT1-containing domain (CS, and the SGT1-specific domain (SGS, and two less conserved variable regions (VR1 and VR2. In the present study, we provide the low-resolution structure of the barley (Hordeum vulgare SGT1 protein in solution and its dimer/monomer equilibrium using small-angle scattering of synchrotron radiation, ab-initio modeling and circular dichroism spectroscopy. The multivariate curve resolution least-square method (MCR-ALS was applied to separate the scattering data of the monomeric and dimeric species from a complex mixture. The models of the barley SGT1 dimer and monomer were formulated using rigid body modeling with ab-initio structure prediction. Both oligomeric forms of barley SGT1 have elongated shapes with unfolded inter-domain regions. Circular dichroism spectroscopy confirmed that the barley SGT1 protein had a modular architecture, with an α-helical TPR domain, a β-sheet sandwich CS domain, and a disordered SGS domain separated by VR1 and VR2 regions. Using molecular docking and ab-initio protein structure prediction, a model of dimerization of the TPR domains was proposed.

    This study evaluated the efficacy of the application of the essential oils of Origanum vulgare L. (OVEO) and Rosmarinus officinalis L. (ROEO) alone and in combination to inhibit Aspergillus flavus URM 4540 and Aspergillus niger URM 5842 in fungal growth media and on Vitis labrusca L. (table grapes). The influence on the autochthonous mycoflora and the physical, physicochemical and sensory characteristics of the grapes during storage (25°C, 12days and 12°C, 24days) were also studied. The application of the essential oils in different concentrations (Minimum Inhibitory Concentration - MIC, 1/2 MIC+1/2 MIC and 1/4 MIC+1/4 MIC) inhibited the mycelial growth and spore germination of the test fungi and inhibited the growth of the assayed fungal strains in artificially contaminated grapes and the autochthonous mycoflora of grapes stored at both room and cold temperatures. In general, the application of OVEO and/or ROEO at sub-lethal concentrations preserved the quality of grapes as measured by their physical, physicochemical and sensory attributes throughout the assessed storage time. These results demonstrate the potential of the combination of OVEO and ROEO at sub-lethal concentrations to control postharvest pathogenic fungi in fruits, particularly, A. flavus and A. niger in table grapes.

    From the rhizosphere of two salt tolerant plant species, Hordeum secalinum and Plantago winteri growing in a naturally salt meadow, 100 strains were isolation on enrichment media for various plant growth-promoting (PGP) functions (ACC deaminase activity, auxin synthesis, calcium phosphate mobilization and nitrogen fixation). Based on the taxonomic affiliation of the isolated bacteria and their enrichment medium 22 isolates were selected to test their growth promotion effect on the crop barley (Hordeum vulgare) under salt stress in pot experiment. In parallel the isolates were characterized in pure culture for their plant growth-promoting activities. Surprisingly the best promotors did not display a promising set of PGP activities. Isolates with multiple PGP-activities in pure culture like Microbacterium natoriense strain E38 and Pseudomonas brassicacearum strain E8 did not promote plant growth. The most effective isolate was strain E108 identified as Curtobacterium flaccumfaciens, which increased barley growth up to 300%. In pure culture strain E108 showed only two out of six plant growth promoting activities and would have been neglected. Our results highlight that screening based on pure culture assays may not be suitable for recognition of best plant growth promotion candidates and could preclude the detection of both new PGPR and new plant promotion mechanisms.

    In the presence of heavy atom perturber Pb2+,silicon dioxide nanoparticle containing fluorescein isothiocyanate (FITC-SiO2) could emit a strong and stable room temperature phosphorescence (RTP) signal on the surface of acetyl cellulose membrane (ACM).It was found in the research that a quantitative specific affinity adsorption (AA) reaction between triticum vulgare lectin (WGA) labeled with luminescent nanoparticle and glucose (g)could be carried on the surface of ACM.The product (WGA-G-WGA-FITC-SiO2) of the reaction could emit a stronger RTP signal,and the △Ip had linear correlation to the content of G.According to the facts above,a new method to determine G by affinity adsorption solid substrate room temperature phosphorimetry (AA-SS-RTP) was established,based on WGA labeled with FITC-SiO2.The detection limit (LD) of this method calculated by 3Sb/k was 0.47 pg·spot-1 (corresponding to a concentration value 1.2 × 10-9 g·mL-1,namely 5.3 × 10-9 mol·L-1),the sensitivity was high.Meanwhile,the mechanism for the determination of G by AA-SS-RTP was discussed.

    Sodium azide (NaN3) has been used in many biological studies as a mutagen. In the present study, the morphological and cytogenetic effects of NaN3 on barley (Hordeum vulgare L.) seedlings were investigated. Seeds of barley were treated with different concentrations of NaN3 (0.5, 1.0, 1.5, 2.0, 2.5, and3.0 mmol/L) and applied for different periods of time (3 and 4 h). Parameters investigated, except for the mitotic index, were determined on Days 7 and 14. Increasing concentrations of NaN3 affected germination rates on Days 7 and 14 following application for 3 and 4 h. Although the length of the roots and leaves was affected by treatment with NaN3 on Day 14 of the germination period, coleoptile length was affected by NaN3 treatment on Day 7. Increasing concentrations of NaN3 and increased treatment period decreased the mitotic index compared with the untreated control. The inhibitory effects of NaN3 on the mitotic index indicate that NaN3 can have genotoxic and mutagenic effects on barley seedlings.

    Full Text Available The effect of solvent polarity (methanol and pentane on the chemical composition of hydrodistilled essential oils (EO’s of Lippia graveolens H.B.K. (MXO and Origanum vulgare L. (EUO was studied by GC-MS. Composition of modified starch microencapsulated EO’s was conducted by headspace-solid-phase microextraction (HS-SPME. The antimicrobial activity of free and microencapsulated EO’s was evaluated. They were tested against Salmonella sp., Brochothrix thermosphacta, Pseudomonas fragi, Lactobacillus plantarum, and Micrococcus luteus. Thymol and carvacrol were among the main components of EO’s and their free and microencapsulated inhibitory activity was tested against M. luteus, showing an additive combined effect. Chemical composition of EO’s varied according to the solvent used for GC analysis and to volatile fraction as evaluated by HS-SPME. Thymol (both solvents was the main component in essential oil of MXO, while carvacrol was the main component of the volatile fraction. EUO showed α-pinene (methanol and γ-terpinene (pentane as major constituents, the latter being the main component of the volatile fraction. EO’s showed good stability after 3 months storage at 4°C, where antimicrobial activity of microencapsulated EO’s remained the same, while free EO’s decreased 41% (MXO and 67% (EUO from initial activity. Microencapsulation retains most antimicrobial activity and improves stability of EO’s from oregano.

    Full Text Available Enterotoxigenic Staphylococcus aureus strains that were isolated from foods were investigated for their ability to develop direct-tolerance and cross-tolerance to sodium chloride (NaCl, potassium chloride (KCl, lactic acid (LA and acetic acid (AA after habituation in sublethal amounts (1/2 of the minimum inhibitory concentration - 1/2 MIC and 1/4 of the minimum inhibitory concentration - 1/4 MIC of Origanum vulgare L. essential oil (OVEO. The habituation of S. aureus to 1/2 MIC and 1/4 MIC of OVEO did not induce direct-tolerance or cross-tolerance in the tested strains, as assessed by modulation of MIC values. Otherwise, exposing the strains to OVEO at sublethal concentrations maintained or increased the sensitivity of the cells to the tested stressing agents because the MIC values of OVEO, NaCl, KCl, LA and AA against the cells that were previously habituated to OVEO remained the same or decreased when compared with non-habituated cells. These data indicate that OVEO does not have an inductive effect on the acquisition of direct-tolerance or cross-tolerance in the tested enterotoxigenic strains of S. aureus to antimicrobial agents that are typically used in food preservation.

    Spring barley ( Hordeum vulgare L. cv. Scarlett) was grown at two CO2 levels (400 vs. 700 ppm) combined with two ozone regimes (ambient vs. double ambient) in climate chambers for four weeks, beginning at seedling emergence. Elevated CO2 concentration significantly increased aboveground biomass, root biomass, and tiller number, whereas double ambient ozone significantly decreased these parameters. These ozone-induced reductions in growth parameters were strongly overridden by 700 ppm CO2. The elevated CO2 level increased C : N ratio of the leaf tissue and leaf starch content but decreased leaf protein levels. Exposure to double ambient ozone did not affect protein content and C : N ratio but dramatically increased leaf starch levels at 700 ppm CO2. Resistance against Drechslera teres (Sacc.) Shoemaker was increased in leaves grown at double ambient ozone but was less obvious at 700 ppm than at 400 ppm CO2. Constitutive activities of beta-1,3-glucanase and chitinase were significantly higher in leaves grown at double ambient ozone compared to ambient ozone levels. The sum of methanol-soluble and alkali-released cell wall-bound aromatic metabolites (i.e., C-glycosylflavones and several structurally unidentified metabolites) and lignin contents did not show any treatment-dependent differences.

    APETALA2/Ethylene-Responsive Factor (AP2/ERF) gene family is plant specific transcription factor. It plays critical roles in development process, tolerance to biotic and abiotic stresses, and responses to plant hormones. However, limited data are available on the contributions of AP2/ERF gene family in barley (Hordeum vulgare L.). In the present study, 121 HvAP2/ERF genes in barley were identified by using bioinformatics methods. A total of 118 HvAP2/ERF (97.5%) genes were located on seven chromosomes. According to phylogenetic classification of AP2/ERF family in Arabidopsis, HvAP2/ERF proteins were divided into AP2 (APETALA2), RAV (Related to ABI3/VP), DREB (dehydration responsive element binding), ERF (ethylene responsive factors) and soloist sub families. The analysis of duplication events indicated that tandem repeat and segmental duplication contributed to the expansion of the AP2/ERF family in barley. HvDREB1s/2s genes displayed various expression patterns under abiotic stress and phytohormone. Taken together, the data generated in this study will be useful for genome-wide analysis to determine the precise role of the HvAP2/ERF gene during barley development, abiotic stress and phytohormone responses with the ultimate goal of improving crop production.

    During the process of Marxism sinification, there exists a phenomenon of vulgarly understanding, inter- pretating and applying the Marxist philosophy. This is embodied in regarding the Marxist philosophy as a tool and excessively emphasizing its actual effect, vulgarizing the philosophic interpretation path, politicalizing the philo- sophic actualization means, materializing the philosophic care, and popularizing the philosophic expression forms. The vulgarization once promoted the prosperity of the Marxist philosophy, but it also brings a heavy histori- cal burden to the current development of philosophy. To clearly recognize the existence of this phenomenon and critically analyzing it in time by "discarding the dross and selecting the essential" is an indispensable work for developing the Marxist philosophy.%在马克思主义哲学中国化进程中,存在着对马克思主义哲学理解、解释和应用的趋“俗”现象。它表现为:哲学学科定位的工具化、实效化;哲学诠释路径的世俗化;哲学实现方式的政治化;哲学关怀的物质化、利益化;哲学表达形式的通俗化。“俗”化现象曾促进了马克思主义哲学的繁荣,但也给当今哲学的发展带来沉重的历史负担。清醒地意识到这种现象的存在并及时进行“去粗取精”的分析批判,是发展马克思主义哲学必不可少的工作。

    This study assessed the inhibitory effects of the essential oil from Origanum vulgare L. (OVEO) on Staphylococcus aureus, Listeria monocytogenes, and a mesophilic starter coculture composed of lactic acid bacteria (Lactococcus lactis subsp. lactis and L. lactis subsp. cremoris) in Brazilian coalho cheese systems. The MIC of OVEO was 2.5 μl/ml against both S. aureus and L. monocytogenes and 0.6 μl/ml against the tested starter coculture. In cheese broth containing OVEO at 0.6 μl/ml, no decrease in viable cell counts (VCC) of both pathogenic bacteria was observed, whereas the initial VCC of the starter coculture decreased approximately 1.0 log CFU/ml after 24 h of exposure at 10°C. OVEO at 1.25 and 2.5 μl/ml caused reductions of up to 2.0 and 2.5 log CFU/ml in S. aureus and L. monocytogenes, respectively, after 24 h of exposure in cheese broth. At these same concentrations, OVEO caused a greater decrease of initial VCC of the starter coculture following 4 h of exposure. Higher concentrations of OVEO were required to decrease the VCC of all target bacteria in semisolid coalho cheese slurry compared with cheese broth. The VCC of Lactococcus spp. in coalho cheese slurry containing OVEO were always lower than those of pathogenic bacteria under the same conditions. These results suggest that the concentrations of OVEO used to control pathogenic bacteria in semihard cheese should be carefully evaluated because of its inhibitory effects on the growth of starter lactic acid cultures used during the production of the product.

    Full Text Available The effects of increasing concentrations of oregano (Origanum vulgare L. and rosemary (Rosmarinus officinalis L. essentials oil (EO on ruminal gas emissions were tested in vitro using 50 mL serum bottles. Each bottle contained a 200 mg substrate (alfalfa hay and corn meal 1:1 and a 20 mL solution composed of a buffered medium and rumen fluid (1:2. The percentage of ruminal fermentation products was quantified by an infrared analyzer. The reduction of total gas production was 6% and 9% respectively when using the 1.5 and 2.0 g/L oregano EO measurements. The reduction of methane production was 55%, 72% and 71% respectively with regard to the 1.0, 1.5 and 2.0 g/L oregano EO doses, while rosemary EO (2.0 g/L reduced the methane production by 9%. The production of ammonia was significantly reduced (59%–78% by all treatments with the exception of rosemary EO at the lowest dose. Dry matter and neutral detergent fiber degradability was reduced by most of the treatments (respectively 4%–9% and 8%–24%. The total volatile fatty acids (VFA concentration was markedly decreased by oregano EO and was not affected by rosemary EO. Both EOs mitigated rumen fermentations, but oregano EO gave rise to the highest reduction in methane and ammonia production. However, further research is needed to evaluate the use of these essential oils as dietary supplements by taking into account the negative effects on feed degradability.

    Barley (Hordeum vulgare L.), genetically modified with the Al(3+) resistance gene of wheat (TaALMT1), was compared with a non-transformed sibling line when grown on an acidic and highly phosphate-fixing ferrosol supplied with a range of phosphorus concentrations. In short-term pot trials (26 days), transgenic barley expressing TaALMT1 (GP-ALMT1) was more efficient than a non-transformed sibling line (GP) at taking up phosphorus on acid soil, but the genotypes did not differ when the soil was limed. Differences in phosphorus uptake efficiency on acid soil could be attributed not only to the differential effects of aluminium toxicity on root growth between the genotypes, but also to differences in phosphorus uptake per unit root length. Although GP-ALMT1 out-performed GP on acid soil, it was still not as efficient at taking up phosphorus as plants grown on limed soil. GP-ALMT1 plants grown in acid soil possessed substantially smaller rhizosheaths than those grown in limed soil, suggesting that root hairs were shorter. This is a probable reason for the lower phosphorus uptake efficiency. When grown to maturity in large pots, GP-ALMT1 plants produced more than twice the grain as GP plants grown on acid soil and 80% of the grain produced by limed controls. Expression of TaALMT1 in barley was not associated with a penalty in either total shoot or grain production in the absence of Al(3+), with both genotypes showing equivalent yields in limed soil. These findings demonstrate that an important crop species can be genetically engineered to successfully increase grain production on an acid soil.

    A C3 monocot, Hordeum vulgare and C3 dicot, Vicia faba, were studied to evaluate the mechanism of inhibition of photosynthesis due to water stress. The net rate of CO2 fixation (A) and transpiration (E) were measured by gas exchange, while the true rate of O2 evolution (J O2) was calculated from chlorophyll fluorescence analysis through the stress cycle (10 to 11 days). With the development of water stress, the decrease in A was more pronounced than the decrease in J O2 resulting in an increased ratio of Photosystem II activity per CO2 fixed which is indicative of an increase in photorespiration due to a decrease in supply of CO2 to Rubisco. Analyses of changes in the J O2 A ratios versus that of CO2 limited photosynthesis in well watered plants, and RuBP pool/RuBP binding sites on Rubisco and RuBP activity, indicate a decreased supply of CO2 to Rubisco under both mild and severe stress is primarily responsible for the decrease in CO2 fixation. In the early stages of stress, the decrease in C i (intercellular CO2) due to stomatal closure can account for the decrease in photosynthesis. Under more severe stress, CO2 supply to Rubisco, calculated from analysis of electron flow and CO2 exchange, continued to decrease. However, C i, calculated from analysis of transpiration and CO2 exchange, either remained constant or increased which may be due to either a decrease in mesophyll conductance or an overestimation of C i by this method due to patchiness in conductance of CO2 to the intercellular space. When plants were rewatered after photosynthesis had dropped to 10-30% of the original rate, both species showed near full recovery within two to four days. PMID:24271534

    Reports about diurnal changes of assimilates in phloem sap are controversial. We determined the diurnal changes of sucrose and amino acid concentrations and fluxes in exudates from cut aphid stylets on tansy leaves (Tanacetum vulgare), and sucrose, amino acid and K(+) concentrations and fluxes in bleeding sap of castor bean pedicel (Ricinus communis). Approximately half of the tansy sieve tubes exhibited a diurnal cycle of sucrose concentrations and fluxes in phloem sap. Data from many tansy plants indicated an increased sucrose flux in the phloem during daytime in case of low N-nutrition, not at high N-nutrition. The sucrose concentration in phloem sap of young Ricinus plants changed marginally between day and night, whereas the sucrose flux increased 1.5-fold during daytime (but not in old Ricinus plants). The amino acid concentrations and fluxes in tansy sieve tubes exhibited a similar diurnal cycle as the sucrose concentrations and fluxes, including their dependence on N-nutrition. The amino acid fluxes, but not the concentrations, in phloem sap of Ricinus were higher at daytime. The sucrose/amino acid ratio showed no diurnal cycle neither in tansy nor in Ricinus. The K(+)-concentrations in phloem sap of Ricinus, but not the K(+) fluxes, decreased slightly during daytime and the sucrose/K(+)-ratio increased. In conclusion, a diurnal cycle was observed in sucrose, amino acid and K(+) fluxes, but not necessarily in concentrations of these assimilates. Because of the large variations between different sieve tubes and different plants, the nutrient delivery to sink tissues is not homeostatic over time.

    WRKY proteins belong to the WRKY-GCM1 superfamily of zinc finger transcription factors that have been subject to a large plant-specific diversification. For the cereal crop barley (Hordeum vulgare), three different WRKY proteins have been characterized so far, as regulators in sucrose signaling, in pathogen defense, and in response to cold and drought, respectively. However, their phylogenetic relationship remained unresolved. In this study, we used the available sequence information to identify a minimum number of 45 barley WRKY transcription factor (HvWRKY) genes. According to their structural features the HvWRKY factors were classified into the previously defined polyphyletic WRKY subgroups 1 to 3. Furthermore, we could assign putative orthologs of the HvWRKY proteins in Arabidopsis and rice. While in most cases clades of orthologous proteins were formed within each group or subgroup, other clades were composed of paralogous proteins for the grasses and Arabidopsis only, which is indicative of specific gene radiation events. To gain insight into their putative functions, we examined expression profiles of WRKY genes from publicly available microarray data resources and found group specific expression patterns. While putative orthologs of the HvWRKY transcription factors have been inferred from phylogenetic sequence analysis, we performed a comparative expression analysis of WRKY genes in Arabidopsis and barley. Indeed, highly correlative expression profiles were found between some of the putative orthologs. HvWRKY genes have not only undergone radiation in monocot or dicot species, but exhibit evolutionary traits specific to grasses. HvWRKY proteins exhibited not only sequence similarities between orthologs with Arabidopsis, but also relatedness in their expression patterns. This correlative expression is indicative for a putative conserved function of related WRKY proteins in mono- and dicot species.

    Full Text Available Background: Oregano (Origanum vulgare, sage (Salvia officinalis, and thyme (Thymus vulgaris are aromatic plants with ornamental, culinary, and phytotherapeutic use all over the world. In Europe, they are traditionally used in the southern countries, particularly in the Mediterranean region. The antimicrobial activities of the essential oils (EOs derived from those plants have captured the attention of scientists as they could be used as alternatives to the increasing resistance of traditional antibiotics against pathogen infections. Therefore, significant interest in the cultivation of various aromatic and medicinal plants is recorded during the last years. However, to gain a proper and marketable chemotype various factors during the cultivation should be considered as the geographical morphology, climatic, and farming conditions. In this frame, we have studied the antimicrobial efficiency of the EOs from oregano, sage, and thyme cultivated under different conditions in a region of NE Greece in comparison to the data available in literature. Methods: Plants were purchased from a certified supplier, planted, and cultivated in an experimental field under different conditions and harvested after 9 months. EOs were extracted by using a Clevenger apparatus and tested for their antibacterial properties (Minimum inhibitory concentration – MIC against clinical isolates of multidrug resistant Escherichia coli (n=27, Klebsiella oxytoca (n=7, and Klebsiella pneumoniae (n=16 strains by using the broth microdilution assay. Results: Our results showed that the most sensitive organism was K. oxytoca with a mean value of MIC of 0.9 µg/mL for oregano EOs and 8.1 µg/mL for thyme. The second most sensitive strain was K. pneumoniae with mean MIC values of 9.5 µg/mL for thyme and 73.5 µg/mL for oregano EOs. E. coli strains were among the most resistant to EOs antimicrobial action as the observed MICs were 24.8–28.6 µg/mL for thyme and above 125 µg/mL for

    Molecular size and net charge of isoforms of pathogenesis-related (PR) chitinase, beta-1,3-glucanase and peroxidase were studied in uninfected barley (Hordeum vulgare L., v. Karat) leaves and in barley leaves infected with the pathogenic fungus Drechslera teres f. teres (Sacch.) Shoem. Molecular characteristics were determined by time-dependent polyacrylamide gradient gel electrophoresis under native conditions and by applying an extended version of the computer program MOL-MASS (Rothe, G. M., Weidmann, H., Electrophoresis 1991, 12, 703-709). Uninfected barley leaves contained predominantly one peroxidase isozyme but also three very weak peroxidases. Activities of all of these three peroxidases increased considerably after infection with Drechslera teres. The molecular masses of peroxidases 1 and 3 were estimated to be 38 +/- 5 and 42 +/- 7 kDa and their apparent valences at pH 8.4 were Z = 3.13 and 3.20, respectively. Amongst the chitinase isoforms, chitinase 1 and chitinase 2 appeared after infection, while chitinase 3 was also observed in uninfected leaves of barley. The molecular mass of chitinase 3 (31 +/- 6 kDa; f/fo = 1.20) was larger than that of chitinase 1 (20 +/- 2 kDa; f/fo = 1.04) and chitinase 2 (23 +/- 3 kDa; f/fo = 1.06). The valence of constitutive chitinase 3 (Z = 1.44 +/- 0.81) at pH 8.4 was lower than that of adaptive chitinase 1 (Z = 3.27 +/- 1.02) and chitinase 2 (Z = 2.96 +/- 1.38). Infection of barley leaves with Drechslera teres also induced the hydrolytic enzyme beta-1,3-glucanase 1; beta-1,3-glucanase 2 appeared in uninfected and in infected leaves. Constitutive beta-1,3-glucanase 2 was smaller (molecular mass 19 +/- kDa; f/fo = 1.05) than adaptive beta-1,3-glucanase 1 (molecular mass 26 +/- 4 kDa; f/fo = 1.07). The valence of adaptive beta-1,3-glucanase 1 (Z = 9.58 +/- 4.17) was approximately threefold that of beta-1,3-glucanase 2 (Z = 2.80 +/- 0.93).

Plastic film, straw pulp film and CK treatment were administrated; the effect was compared by measuring relative humidity of soil surface, soil temperature, soil compaction and water content. The results showed that all four factors monitored were lower in the treatment of straw pulp film than the plastic film, among which water content of the former was significantly reduced than the latter(n=3, P<0.05). In the treatment of straw pulp film comparing to CK, soil compaction was significantly reduced(n=3, P<0.05), while no significant difference in soil temperature was shown between the two. The evaporation of soil moisture reduced dramatically in the treatment of straw pulp film, resulting in a 7.59% statistically significant increase in the water content of soil (n=3, P<0.05). In conclusion, the straw pulp film mulch has significantly improved the water conservation of the soil in Hordeum vulgare farmland.

    International Nuclear Information System (INIS)

    Two year study was carried out to explore the effect of seed rate and row spacing on the fruit yield, essential oil yield and composition of aniseed. The study factors included seed rate (6 g, 12 g, 24 g/10 m2) and row spacing (15 cm, 25 cm, 37.5 cm. A significantly higher fruit yield was produced at narrow row spacing of 15 cm among treatments. Wider row spacing produced markedly higher essential oil than narrow row spacing. Essential oil accumulation decreased as planting densities increased. The major constituent of anise oil was trans-anethole (82.1%) followed by himachalene (7.0%). The quality parameters including estragol, himachalene and trans-anethole were significantly affected by different row spacing. Plant grown at 37.5 cm row spacing accumulated the highest estragol and trans-anethole concentration among the row spacing treatments. It can be concluded that higher plant density and wider row spacing increased the disease infestation and lodging cultivar Enza Zaden in current study exhibited high concentration trans-anethole in essential oil composition therefore is a good quality chemotype.

Fifty patients were randomized to receive one of the five investigational vehicles. Treatment was performed up to complete healing or to a maximum of 29 days. The wound size reduction from baseline was the primary efficacy variable, which was measured by means of a noninvasive laser scanner instrument for wound assessment. In all groups, apart from the foam group, a similar trend toward the reduction of the surface area was observed. The cream showed the greatest effect on the mean reduction of the lesion size. At last visit, six ulcers were healed: two in the cream group, three in the gauze group, and one in the dressing gel group. In the patients treated with the cream, the gauzes, the hydrogel, and the dressing gel, the reduction of lesion size was 40%–50%; the reduction was smaller in the foam group. No impact in terms of age on the healing process was found. The Total Symptoms Score decreased in all groups during the study; a greater efficacy in terms of signs/symptoms was observed in the patients treated with the gauzes. In the dressing gel group, one patient had an infection of the wound after 3 weeks of treatment and 2 of colonization, leading to a systemic antibiotic treatment. The events were judged as nonrelated to the device used. On the basis of the results, it could be argued that the medical device may be useful in the treatment of chronic venous ulcers.

    Full Text Available Investigations were carried out in 2007-2009 on the plots of the Felin Experimental Station belonging to the University of Life Science in Lublin. The studies comprised two cultivation lines of durum wheat (Triticum durum L.: STH 716 and STH 717, as well as the 'Tonacja' cultivar of common wheat (T. aestivum ssp. vulgare L.. Two levels of chemical protection were applied in the cultivation: minimal and complex protection. Infection of wheat roots and stem bases was recorded in each growing season at hard dough stage (87 in Tottman's scale, 1987. After three years of study, the mean disease indexes for the analyzed wheat genotypes in the experimental treatment with minimal protection were 31.13, 30.43 and 38.83 for, respectively, the 'Tonacja' cultivar and the cultivation lines of T. durum STH 716 and STH 717. In the experimental combination with complex protection, after three years of study the disease indexes ranged from 25.26 (T. durum STH 716 to 30.83 (T. durum STH 717. The results of mycological analysis of diseased plants showed that Fusarium spp., especially F. culmorum, F. avenaceum as well as Bipolaris sorokiniana and Rhizoctonia solani, caused root rot and necrosis of wheat stem bases. The analyzed chemical protection levels did not significantly influence grain yield of the investigated genotypes of T. aestivum and T. durum.

    Three types of molecular markers have been compared for their utility in evaluating genetic diversity among cultivars of Hordeum vulgare. Restriction fragment length polymorphisms at 71 sites were scored with the aid of probes corresponding to stress-responsive genes from barley and wheat, coding for a low-molecular-weight heat shock protein, a dehydrin, an aldose reductase homolog, and a 18.9-kDa drought-induced protein of unknown function. Indexes of genetic diversity computed in the total sample and within groups of cultivars (two-rowed and six-rowed, winter and spring varieties) indicated high values of genetic differentiation ( F (ST) >15%). A second assessment of genetic diversity was performed by PCR amplification of genomic DNA using as primers 13 arbitrary oligonucleotides derived from sequences of the same stress-responsive genes. A high degree of polymorphism was uncovered using these markers also, but they yielded low values for F (ST) (genetic distance among cultivars demonstrated a remarkable ability of the RFLPs associated with stress-responsive genes to discriminate on the basis of growth habit. The correlation with production data for the cultivars in different environments was also significant. This "functional genomics" strategy was therefore as informative as the "structural genomics" (SSR-based) approach, but requires the analysis of fewer probes. PMID:11976962

    汉、英文化之间存在空缺是很多译者苦苦思索的问题。后殖民杂合理论主张颠覆和反抗西方文化霸权,在译文中多保留原语的异质文化成分,这对粗俗语的翻译有切实的指导作用。粗俗语的翻译无论在语言文化上还是在翻译策略上,其杂合都是必然而必要的。《水浒传》赛译本和沙译本中粗俗语的翻译都表现出不同程度的杂合。在全球化的今天,粗俗语的翻译应当根据其文化空缺程度的不同,在借助归化策略清除阅读障碍的基础上对原文进行更多的异化处理,只有这样,才能实现两种语言和文化的平等交流,保持文化差异性和混杂性的对立统一。%The translation of Chinese and English vulgarisms with cultural vacancy has long been a headache for translation researchers. "Hybridity" is an important concept in post-colonial studies. In translation studies, the theory of hybridity asserts to resist western cultural hegemony by retaining more heterogeneous elements of the source language. Both English versions of Shui Hu Zhuan by Pearl S. Buck and Sidney Shapiro respectively show different degrees of hybridity. Hybridity in language and culture and the hybridization of domestication and foreignization are unavoidable and necessary in the translation of vulgarisms. The translation of vulgarisms should flexibly promote foreignization on the base of domestication, considering the degree of cultural vacancy. This can not only effectively handle the problem of vulgarism translation but also exert a positive influence on the equal communication of different languages and cultures.

    carpels of one flower, and ( 2 ) diaspores develop from the units of different flowers. None of these dispersal units, which contain up to several seeds in a single diaspore, develops more than two seedlings in one season, indicating that all seeds remain together in the dispersal unit, but are ready to germinate in different years;this phenomenon is called intermittent germination. The annual Tribulus terrestris and the perennial Marrubium vulgare are synaptospermic plants with dispersal units belonging to the two morphologically different diaspore types; M. vulgare also disperses using seeds. Here, we conducted preliminary comparisons and observations on the morphology, vigor, water absorption, and germination characteristics of each dispersal unit. The results showed that mass, length of burs, percentage of appendages accounting for mass, number of seeds, vigor, and water absorption all significantly differed among the synaptospermies of T. terrestris. Conversely, while mass and water absorption significantly differed among M. vulgare dispersal units, no significant differences were observed for vigor, germination, and germination rate. The position of germination in synaptospermy differed between plants. For instance, seeds only germinated on the long thorns of synaptospermids in T. terrestris, indicating nonrandom germination, but no regularity in germination was observed for M. vulgare, indicating random germination. In addition, under the conditions with the highest germination percentage, only part of the seeds germinated in one season for both species, indicating intermittent germination. For different plant life forms, the synaptospermic appendage has the same functions, e.g., protecting seeds, retaining water, dispersing, and germinating. However, the germination behavior of annual plants focuses on population reproduction;therefore, the germination percentage of synaptospermy was high over the season for T. terrestris. Conversely, the germination behavior of

    Full Text Available Sunflower (Helianthus annuus L. oil was coloured with pigments extracted from green leaves. Different amounts (0, 200, 400, 600, and 800 ppm of oleoresin extracted from oregano (Origanum vulgare L. as antioxidant, were added to the coloured oil. As controls, coloured oil without oleoresin (A.C. and pure oil (A.P. were used. The samples were stored at room temperature (10-20 ºC in the dark for up to six months. During this time the oxidation of oleic acid, linoleic acid, peroxides index and the chlorophyll pigments were analized and the colour of the oil was determined. During the first month, only the ratio of chlorophyll to pheophytin changed, whereas all the other parameters stayed constant, independently to the amount of antioxidant added. Since among the treatments A.C. and A.P. not significant differences (p >0,05 were found, for oleic and linoleic methyl ester acids and peroxides index, it can be concluded that the edible, coloured sunflower oil shows an equivalent stability to the pure oil, when stored at darkness for three or six month. There was not observed an evident antioxidant action with the added oregano oleorresin to the coloured oil.Se estudió la estabilidad de aceite comestible de girasol (Helianthus annuus L. de marca comercial sin antioxidantes, coloreado con pigmentos obtenidos de hojas verdes.

    In this study we evaluated the influence of ground purple sea urchin (Paracentrotus lividus) endoskeletons, a processing waste common to all edible sea urchin plants, on the chemical, biochemical and microbiological features of an acidic (pH 5.65) sandy-loam soil. The purple sea urchin endoskeletons were characterized by a high content of total carbonates (∼94%), a moderately alkaline pH in water (pH 7.88) and electrical conductivity values (3.55 mS/cm) very similar to those of commercial lime. To evaluate the influence of the P. lividus endoskeletons on soil properties four different amendment rates were tested, notably 0.5, 1.0, 3.0 and 5.0% based on soil dry weight, and the effects compared with those recorded on unamended control soil. The addition of the purple sea urchin processing waste caused an immediate and significant pH increase which was positively related to the rate of the amendment addition. After a six months equilibration period, the differences in soil pH were still evident and significant increases of electrical conductivity and available phosphorus were also detected in soils with the higher amendment rates. The number of heterotrophic and cellulolytic bacteria and actinomycetes significantly increased after amendment addition while the number of culturable fungi steadily declined. The analysis of the Biolog Community Level Physiological Profile indicated a clear influence of the purple sea urchin processing waste on the structure of the native microbial community while a significant increase of microbial functionality (i.e. dehydrogenase activity) was recorded in soil treated with the higher amendment rates (i.e. 3.0 and 5.0%). The improvement of microbial abundance and functionality as well as the change of the microbial community structure were ascribed to the pH shift induced by the P. lividus processing waste. To investigate possible effects on soil fertility, dwarf bean (Phaseolus vulgaris) and wheat (Triticum vulgare) growth were also

    Full Text Available Four levels of N, P and K nutrition (poor, moderate, satisfactory and high and all their possible combinations with 64 treatments in two replications (128 plots were studied in a long term field trial on barley yield and malting quality. A standard East-European spring barley "Opal" (bred in Czechoslovakia was grown in 1986, 13th year of the agricultural experiment, involving various crops in previous years, on a calcareous loamy chernozem soil. The optimum fertility levels for yield enhancement resulted in the poorest malting quality: low modification and extract but long saccharification time and high protein. To solve this problem the brewing industry will have to apply the well-known technological methods available since growers are not likely to give up their fertilizers. Applying soil and plant analysis data, having knowledge about both soil and plant optimum values, the danger of the excessive use of fertilizers can be realized and decreased.

    Full Text Available Forty one cases of pemphigus vulgaris and thirty cases of pemphigus foliaceus were investigated at Hospital Universitário Clementino Fraga Filho from 1978 to 1999. They were divided into two treatment groups: one group received up to 100 mg of oral prednisone daily and the other group received >120 mg daily. The dose up to 100 mg provided good initial control of pemphigus vulgaris and pemphigus foliaceus and did not increase the mortality rate associated to disease. The dose >120 mg induced higher morbidity. These data allowed us to establish a regimen of oral prednisone (1-2 mg/kg/daily with maximum of 120 mg daily in the treatment of pemphigus vulgaris and pemphigus foliaceus.Quarenta e um casos de pênfigo vulgar e trinta casos de pênfigo foliáceo foram investigados no Hospital Universitário Clementino Fraga Filho, no período 1978-1999. Os pacientes foram divididos em dois grupos de tratamento: um recebendo até 100 mg/dia de prednisona e o outro grupo >120 mg diariamente. Com o primeiro esquema, houve bom controle inicial dos pênfigos sem aumento da taxa de mortalidade associada às doenças. A dose acima de 120 mg induziu maior morbidade. Os resultados permitiram estabelecer um esquema de prednisona (1-2 mg/kg/dia com dose máxima de 120 mg diários no tratamento dos pênfigos vulgar e foliáceo.

  18. Antimicrobial Activity of Essential Oils Extracted from Gamma Irradiated and Stored Anise (Pimenella Anisum) and Black Cumin (Negilla Sativa) Seeds

    International Nuclear Information System (INIS)

    Anise and black cumin seeds were gamma irradiated to doses of 5, 10, 20 and 40 kGy then these seeds were stored to periods of 0, 4, 8 and 12 months. In all treatments, essential oils were extracted at concentrations 500, 1000, 2000, 4000 and 6000 ppm. The inhibitory effect of the different oil concentrations was tested against some microorganism which included bacteria (E. coli and B. cereus), fungi (A. niger and P. citrinum) and yeast (S. lypoytica and K. marxianus). Each of the extracted oil showed different magnitudes to inhibit the growth of the tested microorganisms. However, exposing the aromatic seeds to gamma irradiation before oil extraction was resulted in stimulation in the biological activity of the produced oil. Maximum stimulation was exerted at irradiation dose of 20 kGy. However, the antimicrobial activity of the tested oils was relatively declined when seeds were stored up to 12 months but this decrease was counteracted when seeds were irradiated before storage, thus, gamma radiation showed a beneficial impact to maintain the biological activity of the essential oils during seeds storage.

    In the current study, in vitro inhibitory activity of several essential oils obtained from the cultivated plants, Foeniculum vulgare, Mentha piperita and M. spicata, Ocimum basilicum, Origanum majorana, O. onites, O. vulgare, Satureja cuneifolia, and a number of individual essential oil components of terpene and aromatic types were screened against 10 isolated strains of Klebsiella pneumoniae producing extended-spectrum beta-lactamase (ESBL) enzyme, which makes this microorganism quite resistant against the antibiotics: trimetoprime-sulfametoksazol, sulbactam-ampicilin, clavulonate-amoxicilin, ceftriaxon, cefepime, imipenem, ceftazidime, tobramicine, gentamisine, ofloxacin, and ciprofloksasin. All of the essential oils and the components exerted a remarkable inhibition ranging between 32 and 64 μg/mL against all of these strains as strong as the references (ampicilin and oflaxocin) inhibiting at 32 μg/mL. Besides, chemical compositions of the essential oils were elucidated by gas chromatography-mass spectrometry (GC-MS). The essential oils and the pure components widely found in essential oils screened herein have shown remarkable inhibition against ESBL-producing K. pneumoniae strains, which leads to the suggestion that they may be used as food preservatives for this purpose. Practical Application:  The essential oils obtained from Foeniculum vulgare, Mentha piperita and M. spicata, O.cimum basilicum, Origanum majorana, O. onites, O. vulgare, and Satureja cuneifolia as well as common essential oil components have shown notable inhibitory effects against 10 isolated strains of Klebsiella pneumoniae producing extended-spectrum beta-lactamase (ESBL) enzyme and they might be used as food preservative or ingredient.

    The peculicidal activity of eight plant essential oils in 75% isopropyl alcohol was in vitro investigated. Of them, the substances that were most active against lice were tea tree (Melaleuca), eucalyptus, neem, citronella (Cymbopogon nardus), and clove (Syzygium aromaticum) oils; KT50 was not more than 3 minutes on average; KT95 was 4 minutes. After evaporating the solvent, only five (tea tree, cassia, clove, anise (Anisum vulgare), and Japanese star anise (Illicium anisatum) oils) of the eight test botanical substances were active against lice. At the same time, KT50 and KT95 showed 1.5-5-fold increases. Citronella and anise oils had incomplete ovicidal activity. Since the lice were permethrin-resistant, the efficacy of preparations based on essential oils was much higher than permethrin. PMID:25296426

    干旱胁迫是制约农作物生产的重要限制因素之一,研究并增强作物的抗旱性具有重要意义。SnRK2(Sucrose non-fermenting 1-related protein kinase 2)基因编码一类蔗糖非酵解型蛋白激酶,该酶在ABA信号转录途径和抗渗透胁迫中起着重要作用。以青稞(Hordeum vulgare subsp. vulgare)抗旱品种喜马拉雅10号为材料,利用RT-PCR技术克隆获得了SnRK2基因全长cDNA序列,命名为HbSnRK2.4(登录号:KJ699389)。生物信息学分析表明,该基因全长1310 bp,编码362个氨基酸序列,蛋白分子量为41.94 kD,等电点(pI)为5.96。Prosite Scan分析结果表明,HbSnRK2.4含有多个干旱胁迫响应蛋白的作用位点,如酪蛋白激酶Ⅱ磷酸化位点、酪氨酸激酶磷酸化位点、蛋白激酶C磷酸化位点及N-豆蔻酰化位点等。利用实时定量PCR方法研究了HbSnRK2.4在干旱胁迫条件下及复水后不同时间点的表达情况,发现HbSnRK2.4在土壤绝对含水量为33.4%时表达量最高,随着土壤绝对含水量的下降而下调表达;当达到作物正常生长所需的土壤绝对含水量时又开始上调表达;进行干旱胁迫后(<15.5%)基因表达量下降;复水后8h时恢复正常表达水平。%Drought stress has become one of the important factors that hamper the production of agriculture. Varieties with enhanced drought resistance can be an effective way to solve this problem. SnRK2 gene encoded a kind of Sucrose non-fermenting 1-related protein kinase,which have been thought to play an important role in the ABA signaling pathways and resistance to osmotic stress. However,the exact mechanism underlining is still to be elusive. We presented the isolation of a new SnRK2 gene from Hordeum vulgare subsp. vulgare, nominated as HbSnRK2.4(Accession No. Kj699389)by RT-PCR. The plants were proved to be highly drought tolerance. The gene was 1 310 base pair in length,encoding a peptide of 362 amino acids

    Barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.) possess a significant phytase activity in the mature grains. Maize (Zea mays L.) and rice (Oryza sativa L.) possess little or virtually no pre-formed phytase activity in the mature grain and depend fully on de novo synthesis during...... the “b” type (OsPAPhy_b and ZmPAPhy_b, respectively) were identified. HvPAPhy_a and HvPAPhy_b1/b2 share 86% and TaPAPhya1/a2 and TaPAPhyb1/b2 share up to 90% (TaPAPhy_a2 and TaPAPhy_b2) identical amino acid sequences. In spite of this, PAPhy_a and PAPhy_b isogenes are differentially expressed during...... grain development and germination. In wheat it was demonstrated that “a” and “b” isogene expression is driven by different promoters (~31% identity).

    Full Text Available Croatia is a country of diverse plant use traditions, which are still insufficiently documented. The aim of this study was to document local traditions of using wild food plants around Lake Vrana (northern Dalmatia, Zadar region.  We interviewed 43 inhabitants of six traditional villages north of Lake Vrana. On average 12 species were listed, which in total produced an inventory of 55 food plants and 3 fungi taxa. Wild vegetables were most widely collected, particularly by older women who gathered the plants mainly when herding their flocks of sheep. Wild fruits and mushrooms were rarely collected. The former used to be an important supplementary food for children, or for everyone during times of food shortage, and the latter were relatively rare due to the dry climate and shortage of woods. The most commonly collected plants are wild vegetables: Cichorium intybus, Foeniculum vulgare, Sonchus oleraceus, Asparagus acutifolius, Papaver rhoeas, Rumex pulcher, Daucus carota, Allium ampeloprasum and Silene latifolia.

    It was recently discovered that exposure to small concentrations of the essential oils of sweet fennel (Foeniculum vulgare Mill) or pignut [Hyptis suaveolens (L.) Poit] can be used to control aphids. What is not known is whether these oils also influence honeybee behavior. Experiments using both harnessed and free-flying foragers at concentrations used to control aphids showed that bees readily associated the odors with a reward, discriminated between them, and were not repelled. Honeybees, however, would not consume the oils when mixed with sucrose to create an unconditioned stimulus. An experiment in which harnessed bees consumed various concentrations showed that concentrations greater than 50% were detrimental. The experiments reported here provide further evidence supporting the use of conditioning techniques to evaluate the use of essential oils on honey bee behavior. (author)

    Full Text Available The commercial essential oils of Citrus aurantium L., Cupressus sempervirens L., Eucalyptus globulus Labill., Foeniculum vulgare Mill. and Thymus vulgaris L., isolated by steam distillation by a company of Morocco were evaluated in terms of in vitro antioxidant activity through several methods. In vitro acetylcholinesterase inhibitory activity was also determined. Citrus limon (L. Burm. f. oil was also studied, but it was obtained by peel expression. The best antioxidant was T. vulgaris oil, independent of the method used, mainly due to the presence of the phenolic monoterpenes thymol and carvacrol, which when studied as single compounds also presented the best activities. Concerning the acetylcholinesterase inhibition activity, E. globulus was the most effective. Nevertheless its main components 1,8-cineole and limonene were not the most active, a feature that corresponded to d-3-carene.

    Consumers demand more and more so-called "natural" products and, therefore, the aim of this work was to compare the effects of natural versus synthetic antioxidant preservatives in yogurts. Matricaria recutita L. (chamomile) and Foeniculum vulgare Mill. (fennel) decoctions were tested as natural additives, while potassium sorbate (E202) was used as a synthetic additive. The fortification of yogurts with natural and synthetic antioxidants did not cause significant changes in the yoghurt pH and nutritional value, in comparison with control samples (yogurt without any additive). However, the fortified yogurts showed higher antioxidant activity, mainly the yogurts with natural additives (and among these, the ones with chamomile decoction). Overall, it can be concluded that plant decoctions can be used to develop novel yogurts, by replacing synthetic preservatives and improving the antioxidant properties of the final product, without changing the nutritional profile.

    Globally, there is a trend for healthy food products, preferably incorporating natural bioactive ingredients, replacing synthetic additives. From previous screening studies, extracts of Foeniculum vulgare Mill. (fennel) and Matricaria recutita L. (chamomile) maintained nutritional properties and improved the antioxidant activity of cottage cheese. Nevertheless, this effect was limited to 7 days. Accordingly, aqueous extracts of these plants were microencapsulated in alginate and incorporated into cottage cheese to achieve an extended bioactivity. Plain cottage cheese, and cheese functionalized by direct addition of free decoctions, were prepared and compared. Independently of plant species, "functionalization type" factor did not show a significant effect on the nutritional parameters, as also confirmed in the linear discriminant analysis, where these parameters were not selected as discriminating variables. Furthermore, samples functionalized with microencapsulated extracts showed higher antioxidant activity after the 7th day, thereby demonstrating that the main purpose of this experimental work was achieved.

    Thirteen elements (Na, K, Ca, Mg, Fe, Mn, Cu, Zn, Cr, Co, Cd, Ni and Pb) in 11 different wild edible plants (WEP) (Amaranthus retroflexus, Foeniculum vulgare, Cichorium intybus, Glebionis coronaria, Sonchus spp., Borago officinalis, Diplotaxis tenuifolia, Sinapis arvensis, Papaver rhoeas, Plantago lagopus and Portulaca oleracea) collected from countryside and urban areas of Bari (Italy) were determined. B.officinalis and P.rhoeas could represent good nutritional sources of Mn and Fe, respectively, as well as A.retroflexus and S.arvensis for Ca. High intake of Pb and Cd could come from P.lagopus and A.retroflexus (1.40 and 0.13 mg kg(-1) FW, respectively). WEP may give a substantial contribution to the elements intake for consumers, but in some cases they may supply high level of elements potentially toxic for human health. Anyway, both ANOVA and PCA analyses have highlighted the low influence of the harvesting site on the elements content. PMID:25660854

    In order to evaluate the effects of radioactivity on active vegetal substances, samples of Fennel (Foeniculum vulgare Miller., fructus), Guarana (Paulinia cupana, Kunth, semen), Gingko (gingko biloba, L., folium), and Kawa-Kawa (Piper methysticum G. Forst, rhizoma), were treated with scaling doses (0 to 25 KGy) of gamma radiation (Co{sup 60}). The 'blind test' methodology was used. The active substances from each sample were analysed by qualitative and quantitative methods after radiation. There were no significant differences seen between the control sample (0 KGy) and the irradiated samples. Microbe contamination was significantly reduced, about 10000 CFU/g, with the initial 5 KGy dose. It was concluded that gamma radiation can be used as an alternative procedure to reduce microbiologic contamination in medicinal plants. Before this procedure can be extended to other medicinal plants, more specific analytical methods are recommended to verify possible structural alterations in active vegetal molecules. (author)

    Full Text Available BACKGROUND: Endogenous phytase plays a crucial role in phytate degradation and is thus closely related to nutrient efficiency in barley products. The understanding of genetic information of phytase in barley can provide a useful tool for breeding new barley varieties with high phytase activity. METHODOLOGY/PRINCIPAL FINDINGS: Quantitative trait loci (QTL analysis for phytase activity was conducted using a doubled haploid population. Phytase protein was purified and identified by the LC-ESI MS/MS Shotgun method. Purple acid phosphatase (PAP gene was sequenced and the position was compared with the QTL controlling phytase activity. A major QTL for phytase activity was mapped to chromosome 5 H in barley. The gene controlling phytase activity in the region was named as mqPhy. The gene HvPAP a was mapped to the same position as mqPhy, supporting the colinearity between HvPAP a and mqPhy. CONCLUSIONS/SIGNIFICANCE: It is the first report on QTLs for phytase activity and the results showed that HvPAP a, which shares a same position with the QTL, is a major phytase gene in barley grains.

    The effect of aromatic plants on number of twospotted spider mite (TSSM), Tetranychus urticae Koch, when intercropped with strawberry were assessed in the field. During the first year, chives (Allium schoenoprasum L.), coriander (Coriandrum sativum L.), fennel (Foeniculum vulgare Mill.), garlic (Allium sativum L.), oregano (Origanum vulgare L.), or sweet marjoram (Origanum majorana L.) were intercropped with strawberry. Assessments were performed on TSSM populations by taking six samples from July 20 to September 20, 2012. During the second year, garlic plants were intercropped between rows of strawberry at three densities in greenhouse and field. Mobile forms and eggs numbers (only in field) of TSSM were evaluated from April 18 to June 05 (greenhouse) and June 06 to August 14, 2013 (field). It was found that intercropping with garlic caused a greater reduction of TSSM (up to 52 %) in strawberry plants when higher populations of TSSM occurred in the field. TSSM reduction was found in one sample when fennel and chives were intercropped with strawberries (42 and 50 % reduction, respectively); this also occurred when populations of TSSM were higher. The three densities of garlic plants (one, two and three rows among the strawberry rows) reduced TSSM mobile forms by 49, 53 and 60 % (greenhouse) and 44, 51 and 65 % (field), and eggs by 38, 43 and 64 % (field), respectively. The results suggest that intercropping garlic plants between strawberry rows is a promising strategy to reduce TSSM populations. PMID:27085718

    Full Text Available A repelência de inseticidas botânicos tem se destacado como uma tática promissora no controle alternativo de pragas agrícolas e urbanas, podendo ser um dos componentes do manejo integrado de pragas. Objetivou-se com este trabalho identificar a repelência de inseticidas botânicos sobre fêmeas ápteras de Aphis gossypii Glover. Testes com chance de escolha foram realizados com discos de folha de algodoeiro, imersos nas caldas dos inseticidas e testemunha (água destilada com DMSO a 2%. Utilizou-se azadirachtina (0,075% e os óleos essenciais de Piper hispidinervum CDC, P. aduncum L., Cymbopogon winterianus (L., C. citratus (D.C. Stapf, Foeniculum vulgare Mill, Syzygium aromaticum (L. Merrill e Perry, Cinnamomum zeylanicum Blume, Schinus terebinthifolius Raddi e Chenopodium ambrosioides L. na concentração de 0,05%. C. citratus, C. winterianus, P. aduncum, S. terebinthifolius, azadirachtina e C. zeylanicum apresentaram os maiores percentuais de repelência, 100; 84; 66,67; 64; 60,87 e 48% respectivamente e reduziram a produção de ninfas em 100; 92; 42,9; 87,5; 80,65 e 89,74%, apresentando resultados significativos pelo teste do χ2 ao nível de 10% de probabilidade. Nos testes com F. vulgare (χ2 = 3,66, P = 0,05 as fêmeas de A. gossypii foram atraídas significativamente para os discos tratados e ocorreu um aumento na produção de ninfas nos resultados obtidos para F. vulgare (χ2 = 5,87, P = 0,02 e C. ambrosioides (χ2 = 14,31, P = 0,001.The repellence of botanical insecticides has emerged as a promising technique in the alternative control of urban and agricultural pests, being seen as one component of integrated pest management. The aim of this work was to identify the repellence of botanical insecticides on apterous females of Aphis gossypii Glover. Random-choice tests were carried out with discs from the leaves of cotton plants immersed in insecticide solution and in a control (distilled water with 2% DMSO. Azadirachtin was used
