Resumo:BACKGROUND: Cupressus macrocarpa Hartw and Corymbia citriodora (Hook.) K.D. Hill & L.A.S. Johnson, widely grown in many subtropical areas, are used for commercial purposes, such as in perfumery, cosmetics, and room fresheners. Their potential as a source of antimicrobial compounds may be useful in different applications. METHODS: The chemical composition of essential oils (EOs) from C. macrocarpa branchlets and C. citriodora leaves was analyzed by using gas chromatography-mass spectrometry (GC/MS). Antibacterial and antifungal activities were assessed by the micro-dilution method to determine the minimum inhibitory concentrations (MICs), and minimum fungicidal concentrations (MFCs), and minimum bactericidal concentrations (MBCs). Further, the antioxidant capacity of the EOs was determined via 2,2'-diphenypicrylhydrazyl (DPPH) and ß-carotene-linoleic acid assays. RESULTS: Terpinen-4-ol (23.7%), α-phellandrene (19.2%), α-citronellol (17.3%), and citronellal were the major constituents of EO from C. macrocarpa branchlets, and α-citronellal (56%), α-citronellol (14.7%), citronellol acetate (12.3%), isopulegol, and eucalyptol were the primary constituents of EO from C. citriodora leaves. Antibacterial activity with MIC values of EO from C. citriodora leaves was ranged from 0.06 mg/mL to 0.20 mg/mL, and MBC from 0.12 mg/mL against E. coli to 0.41 mg/mL. EO from C. macrocarpa branchlets showed less activity against bacterial strains. The MIC values against tested fungi of the EO from C. citriodora ranged from 0.11 to 0.52 mg/mL while for EO from C. macrocarpa from 0.29 to 3.21 mg/mL. The MIC and MFC values of EOs against P. funiculosum were lower than those obtained from Ketoconazole (KTZ) (0.20; 0.45; 0.29 and 0.53 mg/mL, respectively, vs 0.21 and 0.41 mg/mL. Antioxidant activity of the EO from C. citriodora was higher than that of the positive control but lower than that of the standard butylhydroxytoluene (BHT) (IC = 5.1 ± 0.1 µg/mL). CONCLUSION: The results indicate that the EO from Egyptian trees such as C. citriodora leaves may possesses strong bactericidal and fungicidal activities and can be used as an agrochemical for controlling plant pathogens and in human disease management which will add crop additive value.

Resumo:Recent concerns regarding the impact of traditional synthetic pesticides on nontarget organisms have generated demand for alternative products with lower environmental impact. This demand has led to increasing focus on plant essential oils as sources of new biopesticides. In this study, we demonstrate that the essential oil of the Alaskan yellow cedar, Cupressus nootkatensis (D. Don) Spach, has activity against hybrid imported fire ant workers, Solenopsis invicta Buren × Solenopsis richteri Forel. In digging assays, ants were repelled by nootka oil and digging continued to be suppressed by nearly 50% in nootka oil-treated sand aged 6 mo in the laboratory. Higher worker mortality was also observed in contact and fumigation assays compared to control checks. In a field drench test, mortality of mounds treated with nootka oil lagged behind mounds treated with bifenthrin treatment for 7 wk, but both nootka oil and bifenthrin had higher mortality than the untreated check at the end of the 12-wk evaluation period. In a band application evaluation, nootka oil plots maintained a 90-95% reduction in fire ant mounds from the 2nd to 17th wk, when new mounds began to intrude on the field plots. The quarantine-approved bifenthrin band treatment maintained 100% control from the 2nd to 24th wk. Although the formulation tested here did not perform to Federal Imported Fire Ant Quarantine standards, other formulations may enable this product to reach 100% control. In addition, nootka oil could be beneficial in situations where ant suppression rather than complete quarantine elimination is the management goal.

Título:Effects of Post-Fire Plant Cover in the Performance of Two Cordilleran Cypress (Austrocedrus chilensis) Seedling Stocktypes Planted in Burned Forests of Northeastern Patagonia, Argentina.

Resumo:Cordilleran cypress (Austrocedrus chilensis [D.Don] Pic. Serm. et Bizarri) forests occupy 140,000 ha along a sharp environmental gradient of central Andean-Patagonia in Argentina. Every summer, about 3200 ha of these forests are affected by wildfires, taking thereafter long time to recover. To accelerate forest recovery, we determined in xeric and mesic cypress stands burned 5 and 2 year before whether survival and growth of two planted cypress seedling stocktypes are affected by plant cover and contrasting precipitation conditions. Two experiments were conducted on each site, involving 100 replicates of two seedling stocktypes, having each significantly different morphological attributes. The experiments comprised a dry and humid growing season on each site. Both stocktypes performed similarly within stands, but differently between stands. In the xeric stand, plant cover had neutral effects on seedling survival, favored seedling height growth in the dry season, and was negative on collar diameter and stem growth. In the mesic site, high plant cover favored survival and height growth, but was inconsequential for collar diameter and stem growth. In this short-term post-fire period, and independent of precipitation received during both seasons (dry or humid), plant cover appears as playing a facilitative role, having neutral or even positive effects on survival and growth of planted seedlings. During the early post-fire successional stages, and besides seedling stocktype, there was a synergistic balance between light and soil moisture that seems to benefit planted seedling performance in burned cypress forests, and especially in mesic sites.

Resumo:OBJECTIVES: To evaluate the prevalence of allergic sensitization in a childhood and adolescent population, to explore age- and gender-specific variations and finally to discover co-sensitivities among allergens. METHODS: A two-stage cross-sectional survey among school-aged children. The two stages of the study involved enrollment of schools and then skin prick testing (SPT) within schools. A total of 675 school children were included in the study. Of those, 231 were diagnosed with allergic rhinitis (AR), according to the medical history as provided by parental-completed questionnaires and positive SPT results. The antigen panel consisted of common allergens and more specifically house dust mites-HDM (Dermatophagoides farinae and Dermatophagoides pteronyssinus), grass mix, trees (olive, cypress and pine), weeds (Parietaria spp.), cat and dog epithelium and moulds (Alternaria spp., Cladosporium spp.). The SPT sensitivity was graded according to SPT-USA Standards. RESULTS: The overall prevalence rate of AR was 34.22%. In total, 93 school children (40.3%) were mono- and 138 (59.7%) were poly-sensitized. Overall, the most prevalent sensitizations in decreasing order were to HDM (59.74%), to grasses (48.9%), to Alternaria (34.6%) and to olive (14.71%). There were no age- and sex-specific differences, except for Alternaria mould that showed a significant prevalence among primary school-aged children and predominance in the female gender, by contrast to grass pollen allergy that was predominant to males. A 32% of SPT-positive individuals were not aware of their allergy, with no statistically significant differences between ages. Co-sensitivities were detected for grass pollens and pine and olive trees, for Alternaria and Cladosporium moulds, for cypress and pine trees, and finally for dog and cat danders. CONCLUSIONS: Given data among school-aged children should be a baseline from which to monitor disease trends and is considered important for the optimal management of AR patients.

Título:Airborne Monoterpenes Emitted from a Cupressus lusitanica Cell Culture Induce a Signaling Cascade that Produces ß-Thujaplicin.

Idioma:eng
Resumo:A cell culture of Cupressus lusitanica was used to investigate the reaction of a plant to certain airborne chemicals. Compared with laboratory and field methods using intact plants or tissues, a cell culture is advantageous because it is not affected by environmental factors, and the experiments are easier to reproduce. When exposed to an elicitor, our cell line produces 10 monoterpenes and ß-thujaplicin, which is a strong phytoalexin. These monoterpenes are emitted into the vapor phase and are expected to play a role in airborne signaling. In the present study, the cells were exposed to monoterpene vapors, and the volatiles present in the culture flasks were monitored. When the culture cells were exposed to low doses of sabinene, we detected γ-terpinene and p-cymene. After exposure to γ-terpinene, we found p-cymene and terpinolene, whereas p-cymene exposure resulted in terpinolene emission. By contrast, the other seven monoterpenes we investigated did not induce any emissions of other monoterpenes. These results strongly suggest that in C. lusitanica a signaling cascade exists that starts with the emission of sabinene and moves to γ-terpinene, p-cymene, and finally to terpinolene, which accelerates the production of the phytoalexin ß-thujaplicin.

Resumo:AIM: The objective of the present study was to evaluate the influence of pollen of Mediterranean Cypress (Cupressus sempervirens) on the effectiveness of the spa and health resort-based treatment (SHRT) of the patients with broncho-pulmonary pathology at the southern coast of the Crimea (SCC). MATERIAL AND METHODS: This article presents the results of the analysis of the data on 122 patients presenting with broncho-pulmonary pathology who received SHRT under the conditions of the Southern Coast of the Crimea. Fifty one (41.8%) of these patients suffered from chronic obstructive pulmonary disease and 71 (58.2%) ones had bronchial asthma. The whole group was comprised of 44 men (36.1%) and 78 women (63.9%). The average (median) age of the patients was 55.8 years. All the participants of the study underwent the comprehensive examination including the general medical and physical examination, complete blood count, the study of sputum cytology and immunological properties of blood including the standard characteristics, IgE and lysozyme levels), evaluation of the respiratory and locomotor (physical) functions with the use of the 6-minute walking test. RESULTS: The aeropollenological study of the aerial environment of the southern coast of the Crimea in the region of Yalta showed that the «bloom¼ of the Mediterranean Cypress occurs during the period from February till April inclusive. The highest concentrations of cypress pollen are observed in March and early April. The overall effectiveness of SHRT for the patients with broncho-pulmonary pathology arriving for the treatment at the southern coast of the Crimea from other Crimean localities does not depend on the period of «flowering¼ (the presence of pollen in the air) of the Mediterranean Cypress. In these patients, the termination of the spa and health resort-based treatment during the «flowering¼ of the Mediterranean Cypress resulted in nothing more than a strained adaptive response manifested as the altered blood leukocyte count. Such reaction is considered to be a natural consequence of intake of antigenic substances into the human body.

Resumo:Lead removal from aqueous solutions by raw cypress (Cupressus sempervirens L.) sawdust (RCS) and its derivative magnesium pretreated biochar (Mg-B) was investigated under static and dynamic conditions through batch and column assays. The Hydrus-1D model was used to estimate the transport parameters of the lead measured breakthrough curves. The batch experiments results showed that Mg-B was very efficient in removing lead compared to RCS and several other previously tested natural and modified materials. The column experiments results indicated that for both RCS and Mg-B, lead breakthrough curves and the related removal efficiencies were mainly dependent on the used initial concentration and the adsorbents bed height. The use of Hydrus-1D showed that the two-site chemical non-equilibrium model describes better the experimental lead breakthrough curves for both RCS and Mg-B as the equilibrium model.

Título:Use of arbuscular mycorrhizal fungi to improve the drought tolerance of Cupressus atlantica G.

Idioma:eng
Resumo:In this study, we investigated whether indigenous arbuscular mycorrhizal (AM) fungi could improve the tolerance of Cupressus atlantica against water deficit. We tested a gradient of watering regime spanning from 90% to 25% of soil retention capacity of water on mycorhized and non-mycorhized seedlings in pot cultures with sterilized and non-sterilized soils. Our result showed a positive impact of AM fungi on shoot height, stem diameter and biomass as well as on the growth rate. We also observed that inoculation with AM fungi significantly improved uptake of minerals by C. atlantica in both sterilized and non-sterilized soils independently of water regimes. We found that mycorhized plants maintained higher relative water content (RWC) and water potential compared with non-mycorhized plants that were subjected to drought-stress regimes (50% and 25% of soil retention capacity). The contents of proline and of soluble sugars showed that their concentrations decreased in non-mycorhized plants subjected to DS. Superoxide dismutase (SOD) and catalase (CAT) activities also decreased in non-mycorhized plants submitted to DS compared to mycorhized plants. The same pattern was observed by measuring peroxidase (POD) enzyme activity. The results demonstrated that AM fungal inoculation promoted the growth and tolerance of C. atlantica against DS in pot cultures. Therefore, mycorrhizal inoculation could be a potential solution for the conservation and reestablishment of C. atlantica in its natural ecosystem.

Resumo:BACKGROUND: People with allergic rhinitis often have laryngeal symptoms (LSs) in addition to nasal symptoms during the pollen-scattering season. OBJECTIVE: To clarify the characteristics of the LSs induced by pollen exposure using an environmental challenge chamber. METHODS: Cypress pollen exposure using an environmental challenge chamber for 25 participants with cypress pollen-induced allergic rhinitis was performed for 3 hours for 2 consecutive days in 3 study courses: namely, pollen exposure under normal nasal breathing and pollen or sham pollen exposure with nasal blockage, which eliminated any allergic reactions in the nasal mucosa. The nasal and LSs scores and the levels of serum inflammatory mediators, including eosinophil cationic protein (ECP), were monitored. Laryngeal examinations and physiologic lung tests were also conducted. RESULTS: Various LSs were reported, and these LSs were significantly elevated during pollen exposure and even under sham exposure with artificial nasal blockage. The pollen exposure with artificial nasal blockage exaggerated the LSs in 32% of the participants and also increased the serum ECP levels. The serum ECP levels did not change after sham exposure. The findings of both laryngeal examinations and lung tests failed to reveal any significant changes. CONCLUSION: Nasal obstruction could induce significant LSs even without pollen exposure. LSs were enhanced by pollen exposure and allergic reactions in the larynx could thus be involved in this enhancement. TRIAL REGISTRATION: clinicaltrials.gov Identifier: UMIN000015667.

Resumo:BACKGROUND: Desert dust originating from arid and semiarid areas is transported to widespread regions, including Japan. Desert dust particles exert adjuvant effects in animals. OBJECTIVE: To examine whether desert dust enhances allergic symptoms in real-life settings and to explore its effect modifiers. METHODS: We conducted an observational study of 3,327 pregnant women during spring and fall in October 2011 to May 2013 in 3 regions in Japan as an adjunct study of the Japan Environment & Children's Study. We acquired participants' daily symptom scores by sending a questionnaire to their mobile phones on high desert-dust days (>0.07/km) and on some randomly selected other days (control days) for each participant. RESULTS: Pregnant women had an increased risk of allergic symptoms on high desert-dust days (adjusted odds ratio [OR], 1.10; 95% CI, 1.04-1.18). The increased OR was mostly driven by those who showed positive IgE to Japanese cedar pollen when pollen simultaneously dispersed (adjusted OR, 1.25; 95% CI, 1.13-1.38), whereas no clear risk increase was observed in the absence of pollen or for participants with negative IgE to Japanese cedar pollen. The risk elevation was observed from low levels of desert dust in a dose-dependent manner even on control days. CONCLUSION: Ambient desert dust level was associated with an increased risk of allergic symptoms in pollen-sensitized pregnant women when pollen was present in the air. The risk increase was dose dependent and was observed from low levels of desert dust. These results support a hypothesis that ambient desert dust particles exert adjuvant effects in human in real-life settings. TRIAL REGISTRATION: clinicaltrials.gov Identifier: UMIN000010826.
