[Ab] Resumo:Phytoremediation experiments were carried out to assess the phytoremediation potential of water caltrop (Trapa natans L.) using municipal wastewater collected from the activated sludge process- (ASP) based municipal wastewater treatment plant. The results revealed that T. natans significantly (P ≤ .05/P ≤ .01/P ≤ .001) reduced the contents of total dissolved solids (TDS), electrical conductivity (EC), biochemical oxygen demand (BOD ), chemical oxygen demand, total Kjeldahl nitrogen, phosphate ([Formula: see text]), sodium (Na ), potassium (K ), calcium (Ca ), magnesium (Mg ), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), lead (Pb), zinc (Zn), standard plate count, and most probable number of the municipal wastewater after phytoremediation experiments. The maximum removal of these parameters was obtained at 60 days of the phytoremediation experiments, but the removal rate of these parameters was gradually increased from 15 to 45 days and it was slightly decreased at 60 days. Most contents of Cd, Cu, Fe, Mn and Zn were translocated in the leaves of T. natans, whereas most contents of Cr and Pb were accumulated in the root of T. natans after phytoremediation experiments. The contents of different biochemical components were recorded in the order of total sugar > crude protein > total ash > crude fiber > total fat in T. natans after phytoremediation of municipal wastewater. Therefore, T. natans was found to be effective for the removal of different parameters of municipal wastewater and can be used effectively to reduce the pollution load of municipal wastewater drained from the ASP-based treatment plants.

[Ab] Resumo:A Gram-staining-positive, aerobic non-spore-forming and short-rod-shaped endophytic actinomycete was isolated from a branch of Sonneratia apetala, designated strain BGMRC0092T and investigated in detail data to determine its taxonomic position. On the basis of the 16S rRNA gene sequence analysis, the results of the phylogenetic analyses indicated that BGMRC0092T was most closely related to Nocardioides alpinus Cr7-14T (96.9 %), Nocardioides oleivorans DSM16090T (96.4 %) and Nocardiodes exalbidus RC825T (96.3 %). The predominant cellular fatty acids of BGMRC0092T were iso-C16 : 0 and C18 : 1ω8c. The major menaquinone was MK-8(H4). The diagnostic diamino acid in the cell-wall peptidoglycan was ll-2,6-diaminopimelic acid. The predominant cell-wall sugars were composed of galactose, mannose, rhamnose and xylose. The polar lipid pattern contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, one unknown phospholipid and three unknown polar lipids. The DNA G+C content was 69.3 mol%. On the basis of phenotypic and chemotaxonomic characteristics and the results of phylogenetic analysis, BGMRC0092T represents a novel species of the genus Nocardioides, for which the name Nocardioides sonneratiae sp. nov. is proposed. The type strain is Nocardioides sonneratiae BGMRC0092T (=KCTC 39565T=NBRC 110251 T=DSM 100390T).

[Ab] Resumo:Plant species have an important role in eco-ditches; however, the Michaelis-Menten kinetic parameters of nutrient uptake, growth rate and purification efficiency of ditch plants and their influences on domestic sewage treatment efficiency are still unclear. Growth rates of all nine species, but especially Lemna gibba, Cladophora and Myriophyllum verticillatum were best in undiluted domestic sewage as opposed to a mixture of domestic sewage. Performance of species to accumulate nutrients was not only species-specific, but was also affected by both sewage treatments. Removal efficiency of nutrients was dependent on both plant species and treatment. Uptake kinetic parameters were significantly affected by both nutrient form and plant species. The maximum uptake rate (Vmax) of NH -N was higher than NO -N. Similarly, Km values for NH -N were greater than NO -N. These results could be used to identify plants for sewage treatment efficiency and enhance water quality in eco-ditch treatment systems.

[Ti] Título:Spasmogenic and spasmolytic activity of rind of Punica granatum Linn.

[Ab] Resumo:BACKGROUND: Rind of Punica granatum is traditionally used in treatment of abdominal cramps and various GIT disorders. So far spasmolytic activity of rind of Punica granatum has been reported using in vitro model. However, its mode of action is not explored yet. Therefore, the current work describes the possible mode of action for spasmolytic activity of methanolic extract of rind of Punica granatum (Pg. Cr). Acute toxicity study is also performed to determine its safe dose range. METHODS: Rind of Punica granatum was subjected to shade drying. Shade dried materials were pulverized using conventional grinder. Grinded materials were macerated in commercial grade methanol. The extract of rind of P. granatum was concentrated using a rotary evaporator. Rabbits' jejunal preparations were mounted in organ bath containing 10 ml Tyrode's solution, constantly aerated with carbogen gas. Pg. Cr was tested on spontaneous rabbits' jejunal preparations in concentrations 0.01, 0.03, 0.1, 0.3, 1.0, 3.0, 5.0 and 10.0 mg/ml. Pg. Cr was also tested on KCl (80 mM)-induced contractions in rabbits' jejunal preparations. Since we observed spasmogenic activity for the first time, hence we also determined the effects of Pg. Cr in presence of atropine (0.03 µM). Pg. Cr was also tested in presence of 0.03 µM of loratadine HCl. Pg. Cr was also tested on barium chloride induced contractions. Calcium Concentration Response Curves (CCRCs) were constructed in the absence and presence of test samples of Pg. Cr in decalcified tissues to explore its possible mode of action. Acute toxicity screening was also performed to determine its safe dose range. RESULTS: Phytochemical screening revealed the presence of saponins, tannins, carbohydrates, proteins, flavonoids, saponins and steroids. However, Pg. Cr tested negative for alkaloids and triterpenoids. Pg. Cr was safe up to 100 mg/kg with its LD 1305 mg/kg. Its respective EC in the absence and presence of atropine, were 9.7 ± 0.3 and 3.12 ± 0.45 mg/ml. In the presence of 0.02 and 0.08 µM of loratadine HCl, respective EC were 5.6 ± 0.4 and 2.8 ± 0.15 mg/ml. EC for relaxant effects on KCl-induced contractions was 8.6 ± 1 mg/ml. In the presence of 0.3 mg/ml of Pg. Cr, a right shift was observed with EC (log [Ca ]M) -1.8 ± 0.09 vs. control EC -2.6 ± 0.01. Similarly, EC for verapamil (0.1 µM) was -2.4 ± 0.011vs. control EC -2.4 ± 0.01. The right shift of P. granatum resembled the right shift of verapamil suggesting for inhibition of voltage gated calcium channels. CONCLUSIONS: P. granatum is safe up to 100 mg/kg. In low concentrations, P. granatum produced spasmogenic activity possibly through involvement of cholinergic and histaminergic receptors. The spasmolytic action may follow inhibition of the voltage gated calcium channels.

[Ab] Resumo:Mangroves are a group of unique plants anchoring in and well adapting to the extreme intertidal environment with high salinity, hypoxia and high temperature and ultraviolet (UV) radiation. Sonneratia caseolaris is a major mangrove tree widely distributed across the West-Indo Pacific region, however the genetic mechanisms of its adaptive evolution are still unclear. In the present study, we performed comparative transcriptome analyses between S. caseolaris and its two non-mangrove relatives, Trapa bispinosa and Duabanga grandiflora, to better understand the evolutionary adaptation of S. caseolaris. We obtained 39.92, 69.96 and 47.78 million high-quality paired-end reads using the Illumina platform and de novo assembled them into 47,954, 73,284 and 66,459 unigenes with low redundancy and high coverage. Of them, 20,181, 28,657 and 25,244 unigenes were successfully assigned to level-2 Gene Ontology (GO) terms, and we found the distribution of GO terms were similar among the three species. Approximate 56% unigenes were involved in "response to stimulus" in all three species. Furthermore, we identified 23 unigenes under positive selection in S. caseolaris, which may be crucial for adaptation of this mangrove species to the extreme intertidal environment.

[Ab] Resumo:Response surface methodology (RSM) was used to optimize experimental conditions for ultrasonic-assisted extraction (UAE) of antioxidant crude polysaccharides (CPS) from Trapa quadrispinosa stems. Antioxidant capacity of polysaccharides was determined by Ferric-Reducing Antioxidant Capacity (FRAC) assay with the method of 1, 10-phenanthroline. The maximum yield of polysaccharides (2.78±0.16%) was obtained under optimal extraction conditions of extraction time, 41min; ratio of water to material, 31.5mL/g; and extraction temperature, 58°C. The maximum antioxidant capacity (19.02±0.24µmol Fe /g) was obtained under the optimal extraction conditions of extraction time, 38min; ratio of water to material, 32mL/g; and extraction temperature, 56°C. These two values were agreed well with predicted yield (2.75%) and antioxidant capacity (18.77µmol Fe /g). Antioxidant activities of CPS were investigated by various assays. The results showed that CPS obtained by UAE showed higher 1,1-Diphenyl-2-picrylhydrazxyl (DPPH), 2,2-azinobis(3-ethylbenzthiazoline)-6-sulfonic acid (ABTS) radical scavenging activities and stronger reducing power, total antioxidant capacity compared with CPS obtained by hot water extraction (HWE).The results indicated that UAE is an advisable method for extraction of antioxidant polysaccharides from the stem of T. quadrispinosa and polysaccharides could be explored as potential antioxidant to use in medicine or functional food.

[Ab] Resumo:Green synthesis by using biological agents has been a simple and effective approach for the synthesis of various forms of nanoparticles. The present investigation was intended to synthesis Ag-NPs and ZnO-NPs under photo-condition using the aqueous extracts of two mangrove plants namely Heritiera fomes and Sonneratia apetala and evaluate their potential biomedical applications. The formation of nanoparticles in aqueous solution of H. fomes and S. apetala under exposure to sun light was validated by change in color and formation of monodispersed NPs with a narrow particle size distribution. Fourier transform infrared spectroscopy (FT-IR) reveals the presence of Oxime and other heterocyclic compounds to be the most probable compounds responsible for the reduction and stability of nanoparticles in the solutions. The synthesized NPs displayed moderate free radical scavenging properties. The anti-inflammatory potential of ZnO-NPs was recorded to be comparatively higher than that of Ag-NP with 79% and 69.1% respectively. The Ag-NPs with unique properties of inhibiting α-amylase (91.14% and 89.16%) were found to be significantly high indicating its antidiabetic property. The synthesized NPs showed varied zone of inhibition (9-16mm) against the tested microbial pathogens. The synthesized nanoparticles possess strong biological activities in terms of antioxidant, anti-inflammatory, antidiabetic and antibacterial, potentials which could be utilized in various biological applications by the cosmetic, food and biomedical industries.

[Ab] Resumo:Punicalagin is the major ellagitannin constituent from leaves of Lafoensia pacari, a Brazilian medicinal plant widely used for the treatment of peptic ulcer and wound healing. Genotoxic, cytotoxic, antigenotoxic, and anticytotoxic effects of punicalagin were assessed using micronucleus (MN) test and comet assay in mice. Due to the extensive use of L. pacari in the wound healing process, we also assessed the angiogenic activity of punicalagin using the chick chorioallantoic membrane (CAM) angiogenic assay. The highest dose of punicalagin (50mg/kg) showed significant cytotoxic effect by MN test and in the co-treatment with cyclophosphamide (CPA), this cytotoxicity was enhanced. Co-treatment, pre-treatment and post-treatment of punicalagin with CPA led to a significant reduction in the number of DNA breaks and in the frequency of CPA-induced MN, indicating antigenotoxic effect. Using the CAM model, punicalagin exhibited angiogenic activity in all doses mainly at the lowest concentration (12.5µg/µL). Therefore, these findings indicate an effective chemopreventive role of punicalagin and a high capacity to induce DNA repair. Also, the angiogenic activity presented by punicalagin in this study could contribute for the processes of tissue repairing and wound healing.

[Ab] Resumo:A higher photosynthesis and lower energetic cost are recognized as important characteristics for invasive species, but whether these traits are also important for the ability of alien mangrove species to become invasive has seldom been reported. A microcosm study was conducted to compare the photosynthetic characteristics, energetic cost indices and other growth traits between two alien species (Sonneratia apetala and S. caseolaris) and four native mangrove species over four seasons in a subtropical mangrove nature reserve in Shenzhen, South China. The aim of the study was to evaluate the invasive potential of Sonneratia based on these physiological responses. The annual average net photosynthetic rate (Pn), stomatal conductance (Gs) and total carbon assimilation per unit leaf area (Atotal) of the two alien Sonneratia species were significantly higher than the values of the native mangroves. In contrast, the opposite results were obtained for the leaf construction cost (CC) per unit dry mass (CCM) and CC per unit area (CCA) values. The higher Atotal and lower CC values resulted in a 72% higher photosynthetic energy-use efficiency (PEUE) for Sonneratia compared to native mangroves, leading to a higher relative growth rate (RGR) of the biomass and height of Sonneratia with the respective values being 51% and 119% higher than those of the native species. Higher photosynthetic indices for Sonneratia compared to native species were found in all seasons except winter, whereas lower CC values were found in all four seasons. The present findings reveal that alien Sonneratia species may adapt well and become invasive in subtropical mangrove wetlands in Shenzhen due to their higher photosynthetic characteristics coupled with lower costs in energy use, leading to a higher PEUE. The comparison of these physiological responses between S. apetala and S. caseolaris reveal that the former species is more invasive than the latter one, thus requiring more attention in future.
