Recessive resistance to Bean common mosaic virus (BCMV) in common bean (Phaseolus vulgaris L.) is governed by four genes that include one strain-nonspecific helper gene bc-u, and three strain-specific genes bc-1, bc-2, and bc-3. The bc-3 gene was identified as an eIF4E translation initiation factor gene mediating resistance through disruption of the interaction between this protein and the VPg protein of the virus. The mode of action of bc-1 and bc-2 in expression of BCMV resistance is unknown, although bc-1 gene was found to affect systemic spread of a related potyvirus, Bean common mosaic necrosis virus. To investigate the possible role of both bc-1 and bc-2 genes in replication, cell-to-cell, and long distance movement of BCMV in P. vulgaris, we tested virus spread of eight BCMV isolates representing pathogroups I, IV, VI, VII, and VIII, in a set of bean differentials expressing different combinations of six resistance alleles including bc-u, bc-1, bc-1 2 , bc-2, bc-2 2 , and bc-3. All studied BCMV isolates were able to replicate and spread in inoculated leaves of bean cultivars harboring bc-u, bc-1, bc-1 2 , bc-2, and bc-2 2 alleles and their combinations, while no BCMV replication was found in inoculated leaves of 'IVT7214' carrying the bc-u, bc-2 and bc-3 genes, except for isolate 1755a capable of overcoming the resistance conferred by bc-2 and bc-3. In contrast, the systemic spread of all BCMV isolates from pathogroups I, IV,VI, VII, and VIII was impaired in common bean cultivars carrying bc-1, bc-1 2 , bc-2, and bc-2 2 alleles. The data suggest that bc-1 and bc-2 recessive resistance genes have no effect on the replication and cell-to-cell movement of BCMV, but affect systemic spread of BCMV in common bean. The BCMV resistance conferred by bc-1 and bc-2 and affecting systemic spread was found only partially effective when these two genes were expressed singly. The efficiency of the restriction of the systemic spread of the virus was greatly enhanced when

Halogenated natural products (HNPs) of marine origin are increasingly recognized as critical residues in foodstuff (e. g. fish) and environmental samples (e. g. marine mammals and birds). Some of these HNPs (Q1, MHC-1, BC-2, and HDBPs including BC-10) were detected in diverse fish and marine mammal samples at concentrations sometimes exceeding those of PCBs, DDT, and other anthropogenic pollutants. Recent studies with marine mammal samples from Australia led to the detection of six abundant HNPs (Q1, BC-1, BC-2, BC-3, BC-10, and BC-11). In the meantime, Q1 was identified as heptachloro-1{sup '}-methyl-1,2{sup '}-bipyrrole, BC-2 as 4,6-dibromo-2-(2{sup '},4{sup '}-dibromo)phenoxyanisole, BC- 10 as 1,1{sup '}-dimethyl-3,3{sup '},4,4{sup '}-tetrabromo-5,5{sup '}-dichloro-2,2{sup '}-bipyrrole, and BC-11 as 3,5-dibromo- 2-(3{sup '},5{sup '}-dibromo,2{sup '}-methoxy)phenoxyanisole. However the identity of BC-1 and BC-3 remained unclear. The goal of the present study was the identification of BC-3. The tetrabromo compound BC-3 has previously been detected in marine mammals from four continents. Furthermore, we attempted establishing quantitative concentrations in diverse marine biota samples.

BC3 algorithm is a secret-key cryptography algorithm developed with two considerations: robustness and implementation efficiency. This algorithm has been implemented on software and has good performance compared to AES algorithm. BC3 is improvement of BC2 and AE cryptographic algorithm and it is expected to have the same level of robustness and to gain competitive advantages in the implementation aspect. The development of the architecture gives much attention on (1 resource sharing and (2 having single clock for each round. It exploits regularity of the algorithm. This architecture is then implemented on an FPGA. This implementation is three times smaller area than AES, but about five times faster. Furthermore, this BC3 hardware implementation has better performance compared to BC3 software both in key expansion stage and randomizing stage. For the future, the security of this implementation must be reviewed especially against side channel attack.

Among the CCK-B receptor agonists reported to date, the two modified peptides BC 264 and BC 254 display a high affinity and selectivity for this binding site and are highly protected from enzymatic degradation. Recently, we reported the biological properties of a tritiated analog of this agonist, [[sup 3]H]pBC 264, which fullfils all the criteria required for in vitro as well as in vivo studies of the CCK-B receptor. On the other hand, BC 254 displays a high affinity for the CCK-B binding sites in the guinea-pig (K[sub i] = 0.56 nM) while its affinity in the rat is more than 60-fold lower, a difference which could be due to the occurrence of CCK-B receptor subtypes. In the present paper, we report the synthesis of [[sup 3]H]pBC 264 and of the new tritiated ligand [[sup 3]H]pBC 254 using [[sup 3]H] NPS (N-succinimidyl[2,3-[sup 3]H]propionate) as labelling agent. These two probes have high specific activity (70-100 Ci/mmol) and will enable extensive studies of the CCK-B receptors to be carried out. (author).

The haloacyltris(trifluoromethyl)borate anions [(CF3)3BC(O)Hal]- (Hal=F, Cl, Br, I) have been synthesized by reacting (CF3)3BCO with either MHal (M=K, Cs; Hal=F) in SO2 or MHal (M=[nBu4N]+, [Et4N]+, [Ph4P]+; Hal=Cl, Br, I) in dichloromethane. Metathesis reactions of the fluoroacyl complex with Me3SiHal (Hal=Cl, Br, I) led to the formation of its higher homologues. The thermal stabilities of the haloacyltris(trifluoromethyl)borates decrease from the fluorine to the iodine derivative. The chemical reactivities decrease in the same order as demonstrated by a series of selected reactions. The new [(CF3)3BC(O)Hal]- (Hal=F, Cl, Br) salts are used as starting materials in the syntheses of novel compounds that contain the (CF3)3B-C fragment. All borate anions [(CF3)3BC(O)Hal]- (Hal=F, Cl, Br, I) have been characterized by multinuclear NMR spectroscopy (11B, 13C, 17O, 19F) and vibrational spectroscopy. [PPh4][(CF3)3BC(O)Br] crystallizes in the monoclinic space group P2/c (no. 13) and the bond parameters are compared with those of (CF3)3BCO and K[(CF3)3BC(O)F]. The interpretation of the spectroscopic and structural data are supported by DFT calculations [B3LYP/6-311+G(d)].

The electronic and magnetic properties of Fe-, Co-, and Ni-decorated two dimensional (2D) BC3 are systematically investigated by first-principles calculations. We find that the Fe, Co, and Ni atoms can be strongly adsorbed on the hollow sites of 2D BC3. Fe and Co adatoms are more stable when adsorbed on the hollow sites of the carbon rings in the 2D BC3, while the hollow sites of boron-carbon rings in the 2D BC3 are the most stable sites for the adsorption of Ni adatoms. These proposed metal-BC3 complexes exhibit interesting electronic and magnetic behaviors. In particular, the Fe-BC3 and Co-BC3 complexes are metals with magnetic ground states , while the Ni-BC3 complex behaves as a nonmagnetic semiconductor with a direct bandgap. Furthermore, our magnetic analysis reveals that induced magnetism in the Fe-BC3 and Co-BC3 complexes arises from their local magnetic moments. Functionalization of 2D BC3 through these metal-adatom adsorption appears to be a promising way to extend its applications.

For flexible film supercapacitor, high areal capacitance is a main evaluating indicator. In this paper, bacterial cellulose (BC) with special three-dimensional structure was used as the natural flexible base material. Fe3O4 nanoparticles with average diameter of 20 nm were synthesized on the surface of BC fibers. The conductive path polypyrrole (PPy) was introduced as shell of BC/Fe3O4 fibers to further improve the pseudo capacitance in 1 mol/L H2SO4 solution. Besides, the BC/Fe3O4@PPy was used for supercapacitor application in acid electrolyte, and delivered higher areal capacitance compared to other Fe3O4 composites in previous reports. The obtained BC/Fe3O4@PPy film showed excellent mechanical strength (tensile strength reached 11 MPa), high areal specific capacitance (5.4 F cm-2 at active mass of 8.4 mg cm-2), and long cycle life (1.95 F cm-2 over 3500 cycles).

The 100-BC-1, 100-BC-2, 100-DR-1, and 100-DR-2 Group 3 waste sites contain 22 past-practice liquid waste disposal sites and process effluent piping associated with four plutonium-production nuclear reactors that operated from 1944 to 1967. The 100-BC-1, 100-BC-2, 100-DR-1, and 100-DR-2 Group 3 waste sites are the third set of Hanford 100 Area sites to undergo remediation to the extent practicable. Like the sites listed in Groups 1 and 2, the Group 3 sites are considered high-priority because of the contaminants present and their proximity to the Columbia River. Remediation of the 100-BC-1, 100-HR-1 and 100-DR-1 radioactive liquid waste sites is planned to occur in two phases: The first phase, which has been completed, was a demonstration project in the 100-B/C Area to test field techniques and acquire contamination data. The second phase is full-scale remediation of all the reactor areas, starting in the 10-B/C Area, using the field experience gained in the first phase and each subsequent reactor area remediation. This document provides the DQO in support of remediation sampling and analysis at selected sites in the 100-B/C and 100-D Areas

We have systematically investigated the effect of hydrogen adsorption on a single BC 3 sheet as well as graphene using first-principles calculations. Specifically, a comparative study of the energetically favorable atomic configurations for both H-adsorbed BC 3 sheets and graphene at different hydrogen concentrations ranging from 1/32 to 4/32 ML and 1/8 to 1 ML was undertaken. The preferred hydrogen arrangement on the single BC 3 sheet and graphene was found to have the same property as that of the adsorbed H atoms on the neighboring C atoms on the opposite sides of the sheet. Moreover, at low coverage of H, the pattern of hydrogen adsorption on the BC 3 shows a proclivity toward formation on the same ring, contrasting their behavior on graphene where they tend to form the elongated zigzag chains instead. Lastly, both the hydrogenated BC 3 sheet and graphene exhibit alternation of semiconducting and metallic properties as the H concentration is increased. These results suggest the possibility of manipulating the bandgaps in a single BC 3 sheet and graphene by controlling the H concentrations on the BC 3 sheet and graphene.

Infective larvae (L3) of Strongylus vulgaris have limited energy stores for host finding and for infection. For transmission to occur, the larvae must have sufficient energy to (a) migrate onto grass, where they are ingested by their equine host (host finding), and (b) penetrate into the host gut. This study is designed to test the hypothesis that L3 larvae of S. vulgaris partition their energy stores between locomotory activity (used in host finding) and infection activity (penetration). Chronic locomotory activity was stimulated by incubating S. vulgaris L3 larvae at a constant temperature (38 C). After 8 days of treatment, locomotory activity ceased (exhaustion). Exhausted L3 larvae had significantly decreased total lipid when compared to controls (P vulgaris L3 larvae are comprised of 9 fatty acids, some of which are depleted in exhausted worms (14:0, 14:1, 16:0, 16:1, 18:1, 18:2), whereas others (18:0, 20:4, 24:0) remain unchanged. These data suggest that specific fatty acids provide the energy source for locomotory activity in S. vulgaris. Exhausted L3 larvae were also less able to penetrate host cecal tissue in in vitro penetration assays when compared to controls (P vulgaris L3 larvae partition their energy stores between host-finding and infection activities. A comparison of lipid storage profiles in the L3 larvae of 4 nematode species with similar transmission strategies (S. vulgaris, Strongylus edentatus, Strongylus equinus, and Haemonchus contortus) revealed similarities in the fatty acid composition of these species. These data suggest a relationship between transmission patterns and energy storage strategies in the L3 larvae of nematode parasites of vertebrates.

In this research removal of NH 3 -N, NO 3 -N and PO 4 -P nutrients from municipal wastewater was studied, using Chlorella vulgaris, Pseudomonas putida, Bacillus cereus and an artificial consortium of them. The objective is to analyze the performance of these microorganisms and their consortium, which has not been previously studied for nutrient removal in municipal wastewater. A model wastewater was prepared simulating the physicochemical characteristics found at the wastewater plant in Chapala, Mexico. Experiments were carried out without adding an external carbon source. Results indicate that nutrient removal with Chlorella vulgaris was the most efficient with a removal of 24.03% of NO 3 -N, 80.62% of NH 3 -N and 4.30% of PO 4 -P. With Bacillus cereus the results were 8.40% of NO 3 -N, 28.80% of NH 3 -N and 3.80% of PO 4 -P. The removals with Pseudomonas putida were 2.50% of NO 3 -N, 41.80 of NH 3 -N and 4.30% of PO 4 -P. The consortium of Chlorella vulgaris-Bacillus cereus-Pseudomonas putida removed 29.40% of NO 3 -N, 4.2% of NH 3 -N and 8.4% of PO 4 -P. The highest biomass production was with Bacillus cereus (450 mg/l) followed by Pseudomonas putida (444 mg/l), the consortium (205 mg/l) and Chlorella vulgaris (88.9 mg/l). This study highlights the utility of these microorganisms for nutrient removal in wastewater treatments.

The adsorption behaviors of toxic gas molecules (NO, CO, NO2, and NH3) on the graphene-like boron carbide (BC3) are investigated using first-principle density functional theory. The graphene-like BC3 monolayer is a semiconductor with a band gap of 0.733 eV. It is discovered that all the above gas molecules are chemisorbed on the BC3 sheet while they retain their molecular forms. It is also revealed that the NO2 gas molecule could be dissociated into NO and O species through the adsorption process. The amounts of charge transfer upon adsorption of CO and NH3 gas molecules on the BC3 are found to be small. The band gap changes in BC3 as a result of interactions with CO and NH3 are only 4.63% and 16.7%, indicating that the BC3-based sensor has a low and moderate sensitivity to CO and NH3, respectively. Contrariwise, upon adsorption of NO or NO2 on the BC3, significant charges are transferred from the molecules to the BC3 sheet, causing a semiconductor-metal and semiconductor-p type semiconductor transition. Our study suggests that the BC3-based sensor has a high potential for NO and NO2 detection due to the significant conductance changes, moderate adsorption energy, and short recovery time. More excitingly, the BC3 is a likely catalyst for dissociation of the NO2 gas molecule.

A post-mortem survey was carried out on 46 Sardinian horses to evaluate the presence of Strongylus vulgaris and associated pathology. Horses were from local farms and had been treated with broad-spectrum anthelmintics at least 3 times a year. Examination of the cranial mesenteric arterial system (CMAS) showed parasite-induced lesions in all horses. S. vulgaris larvae were found in 39% of examined arteries, while their detection rate in coprocultures was 4%. Histology, carried out on 26 horses, showed mainly chronic and chronic-active lesions. Histometry showed a significant increase in thickness of the arterial wall, in particular of the intima tunic and adventitia tunic of the ileocolic artery and its colic branch. MCV, MCHC and alpha2, beta and gamma globulins were increased in horses with S. vulgaris larvae in the arteries, while the albumin/globulin ratio was decreased. Horses that were positive on faecal examination showed decreased values for RBC, PCV and the albumin/globulin ratio. Although several studies have shown a dramatic decrease of S. vulgaris infection worldwide, our data show that this parasite continues to exert its pathogenic role, even when its detection rate is quite low within the strongyle population infecting horses.

Recently, a new two-dimensional (2D) material, the 2D BC3 crystal, has been synthesized. Here, the mechanical control of the electro-optical properties of monolayer and bilayer BC3 by applying the biaxial strain is investigated. The electronic structure calculations showed that the strain-free monolayer and bilayer BC3 are indirect band-gap semiconductors with band gap of 0.62 and 0.29 eV, respectively, where the conduction band minimum (CBM) is at the M point whereas the valence band maximum (VBM) is at the Γ point. The doubly degenerated bands in the monolayer BC3 are splitted in the bilayer BC3 due to the interlayer interactions. Both monolayer and bilayer BC3 remain indirect gap semiconductor under biaxial tensile strain and their band gaps increases with strain. On the other hand, by increasing the magnitude of tensile strain, the optical spectra shift to the lower energies and the static dielectric constant increases. These findings suggest the potential of strain-engineered 2D BC3 in electronic and optoelectronic device applications.

Acid-base properties of 1-methyl-1,4-dilhydroborabenzene, CH3BC5H6

Ion cyclotron resonance techniques are employed to determine the gas-phase Bronsted and Lewis acidities as well as the Bronsted basicity of 1-methyl-1,4-dihydroborabenzene, CH 3 BC 5 H 6 . The ring proton is found to be highly acidic with PA(CH 3 BC 5 H 5 - ) = 337 +- 3 kcal/mol. This acidity results from the formation of 6π electron aromatic anion CH 3 BC 5 H 5 - , which is isoelectronic with toluene. Both the Lewis acidity toward F - as a reference base and the proton basicity of the parent molecule suggest that there is little interaction between the diene π system and the electron-deficient boron. This is further confirmed by the similarity of both negative and positive ion chemistry of the borabenzene to that of aliphatic boranes

Full Text Available Introduction: The etiopathogenesis of acne vulgaris is multifactorial, and its therapy is prolonged course that might be not accepted by many patients. Most recently TCA 35% one session peeling gave complete clearance and full remission for active acne vulgaris. Lactic acid has been used effectively as therapeutic topical agents for many skin diseases. Aim: To evaluate the efficacy and safety of chemical peeling using 88% lactic acid solution in the treatment of active acne vulgaris. Material and Methods: This clinical, interventional, therapeutic study was done at the Department of Dermatology, Baghdad Teaching Hospital, during the period from October 2012 to October 2013. Twenty five patients with active acne vulgaris were included, 15 (60% females and 10 (40% males and their ages ranged from 16-36 (21.5000± 5.46279 years. Fifteen patients were associated with acne scars. Three chemical peels using 88% lactic acid solution was carried out two weeks apart for patients with active acne vulgaris with or without scarring. Scoring for active acne vulgaris and acne scar was done for each case before and after operation to evaluate the severity of acne and the degree of scar before and after treatment. All patients were with Fitzpatrick’s skin types III and IV. Patients were followed up every two weeks during period of therapy and monthly for 3 months after stopping the treatment. Results: Twenty five patients with active acne vulgaris were treated with 3 sessions of lactic acid, fifteen patients had associated acne scar. Scoring for active acne vulgaris including papules and pustules showed highly statistically significant reduction after 2 weeks of therapy (p=0.0001, after 4 weeks (p=0.0001and after 6 weeks (p=0.0001, with percent reduction 87.2% for papules and 94% for pustules after end of sessions while after 3 months follow up the reduction rate for papules 93.8% and p-value (p=0.001 and for pustules 97.6% and (p=0.0001.

Production of inositol trisphosphates upon α-adrenergic stimulation in BC3H-1 muscle cells

Activation of α 1 -adrenergic receptors in BC3H-1 muscle cells rapidly mobilizes intracellular and results in a paradoxically slower accumulation of inositol trisphosphate. A possible explanation for this discrepancy may be provided by the recent findings of Irvine et al. of additional Ins P3 isomers besides the Ca ++ -mobilizing isomer, Ins 1,4,5-P3. They have eluted and separated the inositol phosphates of BC3H-1 cells with an NH 4 + x HCO 2 - /H 3 PO 4 gradient on a Whatman Partisil 10SAX column using Hewlett-Packard HPLC. Commercial [ 3 H]Ins 1,4,5-P3 and [ 3 H]inositol phosphates from carbachol-stimulated parotid glands were used as standards. Little or no Ins 1,3,4-P3 could be detected in control or phenylephrine-treated BC3H-1 cells. Ins 1,4,5-P3 followed the pattern of agonist stimulation observed previously. As a positive control, Ins P3 isomers were also measured in 1321N1 astrocytoma cells. Muscarinic stimulation of 1321N1 cells results in both the rapid accumulation of Ins P3 and Ca ++ mobilization. There is no detectable basal Ins 1,3,4-P3, but carbachol stimulates a rapid production of this compound in 1321N1 cells. Agonist activation also results in a rapid increase in Ins 1,4,5-P3 above basal values. These studies indicate that Ins 1,3,4-P3 does not contribute to the InsP3 signal in BC3H-1 cells and multiple mechanisms may exist for the coupling of receptors to PI turnover

A series of propargyl amides were prepared and their reactions with the Lewis acidic compound B(C6F5)3 were investigated. These reactions were shown to afford novel heterocycles under mild conditions. The reaction of a variety of N-substituted propargyl amides with B(C6F5)3 led to an intramolecular oxo-boration cyclisation reaction, which afforded the 5-alkylidene-4,5-dihydrooxazolium borate species. Secondary propargyl amides gave oxazoles in B(C6F5)3 mediated (catalytic) cyclisation reactions. In the special case of disubstitution adjacent to the nitrogen atom, 1,1-carboboration is favoured as a result of the increased steric hindrance (1,3-allylic strain) in the 5-alkylidene-4,5-dihydrooxazolium borate species.

Acne vulgaris is a common and chronic skin disease, and is a frequent source of morbidity for affected patients. Treatment of acne vulgaris is often difficult due to the multifactorial nature of this disease. Combination therapy, such as that containing clindamycin and benzoyl peroxide, has become the standard of care. Several fixed formulations of clindamycin 1% and benzoyl peroxide of varying concentrations are available and have been used with considerable success. The major limitation is irritation and dryness from higher concentrations of benzoyl peroxide, and a combination providing optimal efficacy and tolerability has yet to be determined. Recently, a clindamycin and benzoyl peroxide 3.75% fixed combination formulation was developed. Studies have suggested that this formulation may be a safe and effective treatment regimen for patients with acne vulgaris. Here, we provide a brief review of acne pathogenesis, benzoyl peroxide and clindamycin, and profile a new Clindamycin-BP 3.75% fixed combination gel for the treatment of moderate-to-severe acne vulgaris.

Measurements of $B_c^+$ production and mass are performed with the decay mode $B_c^+ \\to J/\\psi \\pi^+$ using 0.37 fb$^{-1}$ of data collected in $pp$ collisions at $\\sqrt{s}=7$~TeV by the LHCb experiment. The ratio of the production cross-section times branching fraction between the $B_c^+ \\to J/\\psi \\pi^+$ and the $B^+ \\to J/\\psi K^+$ decays is measured to be $(0.68 \\pm 0.10\\,({\\rm stat.}) \\pm 0.03\\,({\\rm syst.}) \\pm 0.05\\,({\\rm lifetime}) )\\%$ for $B_c^+$ and $B^+$ mesons with transverse momenta $p_{\\rm T}>4~$GeV/$c$ and pseudorapidities $2.5<\\eta<4.5$. The $B_c^+$ mass is directly measured to be $6273.7 \\pm 1.3\\,({\\rm stat.}) \\pm 1.6 \\,({\\rm syst.})$~MeV/$c^2$, and the measured mass difference with respect to the $B^+$ meson is $M(B_c^+)-M(B^+) = 994.6 \\pm 1.3\\,({\\rm stat.}) \\pm 0.6\\,({\\rm syst.})$~MeV/$c^2$.

Hydroxyurea inhibits mitotic activity in cells of the antheridial filaments of Chara vulgaris by blocking phase S and phase G 2 . Blocking of cells in phase G 2 also occurs in the case of the root meristem cells of Helianthus annuus and Vicia faba var. minor. 3 H-thine incorporation confirmed autoradiographically the blocking of cells of the antheridial filaments in Chara vulgaris at phase S and slowing down of the rate of DNA replication. Incubation with 3 H-phenylalanine demonstrated that hydroxyurea inhibits protein synthesis. (author)

Full Text Available Abstract Background: Acne vulgaris is chronic inflamatory disease of the pilosebaceous unit.Patients experience psychological burdens like depression ,anxiety, and low self- esteem. Isotretinoin is used in the treatment of severe and recalcitrant acne; however, this treatment is associated with a number of partialy common adverse effects that it sometimes may stop the process of treatment. The aim of this study is to evaluate the effect of oral omega 3 on side-effects of isotretinoin . Materials and Methods: One hundred eighteen patients with severe acne vulgaris were randomly divided into two groups. Control group received isotretinoin (0.5 mg∕kg alone and case group received isotretinoin (0.5 mg∕kg combined with omega 3 (2 capsuls daily. The duration of treatment was 16 weeks.Mucocutaneous side-effects were assessed in patients(4, 8, 12, 16th wk. Results: Lip dryness (4, 8, 12th wk and dryness of nose, skin, eye in the 4 th week in the patients with acne vulgaris treated with isotretinoin and omega3 was lesser than in the patients treated with isotretinoin alone, that this difference was statistically significant (p<0.001. Conclusion: Based on the results of this study, Omega 3 decreased the mucocutaneous side effects in the patients with acne vulgaris who received isotretinoin.

The BC2N as an example of boron-carbon-nitride (BCN), has the analogous structure as the graphene and boron nitride. It is predicted to have controllable electronic properties. Therefore, the analytical study on the engineer-able band gap of the BC2N is carried out based on the schematic structure of BC2N. The Nearest Neighbour Tight Binding (NNTB) model is employed with the dispersion relation and the density of state (DOS) as the main band gap analysing parameter. The results show that the hopping integrals having the significant effect on the band gap, band structure and DOS of BC2N nanowire (BC2NNW) need to be taken into consideration. The presented model indicates consistent trends with the published computational results around the Dirac points with the extracted band gap of 0.12 eV. Also, it is distinguished that wide energy gap of boron nitride (BN) is successfully narrowed by this carbon doped material which assures the application of BC2N on the nanoelectronics and optoelectronics in the near future.

A baryonic decay of the B(c)(+) meson, B(c)(+) → J/ψppπ(+), is observed for the first time, with a significance of 7.3 standard deviations, in pp collision data collected with the LHCb detector and corresponding to an integrated luminosity of 3.0 fb(-1) taken at center-of-mass energies of 7 and 8 TeV. With the B(c)(+) → J/ψπ(+) decay as the normalization channel, the ratio of branching fractions is measured to be B(B(c)(+) → J/ψppπ(+))/B(B(c)(+) → J/ψπ(+)) = 0.143(-0.034)(+0.039)(stat) ± 0.013(syst). The mass of the B(c)(+) meson is determined as M(B(c)(+) = 6274.0 ± 1.8(stat) ± 0.4(syst) MeV/c(2), using the B(c)(+) → J/ψppπ(+) channel.

Three flavonoids were isolated from the leaf MeOH extracts of Primula latifolia Lapeyr. and Primula vulgaris Hudson collected from Italian Alps: rutin (1) and kaempferol 3-neohesperidoside (2) from P. latifolia, and kaempferol 3-β-O-glucopyranosyl-(1 → 2) gentiobioside (3) from P. vulgaris. The structures were assigned on the basis of their (1)H and (13)C NMR data, including those derived from 2D NMR, as well as on HPLC-MS results. This article is the first to report on P. vulgaris tissue flavonoids after Harborne's study in 1968 and the first work ever on these compounds from P. latifolia.

A method of Agrobacterium-mediated genetic transformation of sugarbeet (Beta vulgaris L.) with vacuum infiltration has been developed. Aseptic 3-weeks old etiolated seedlings of two diploid O-type sugarbeet lines (KS3 and KS7) have been used for genetic transformation. Transgenic sugarbeet plants carrying the reporter beta-glucuronidase gene have been selected for their resistance to glufosinate ammonium herbicide. Integration of transgenes into sugarbeet genome was confirmed with GUS assay and PCR using primers for bar and gusA genes.

Full Text Available Tyrosine phosphorylation and dephosphorylation have emerged as fundamentally important mechanisms of signal transduction and regulation in eukaryotic cells, governing many processes, but little has been known about their functions in filamentous fungi. In this study, we deleted two putative protein tyrosine phosphatase (PTP genes (BcPTPA and BcPTPB in Botrytis cinerea, encoding the orthologs of Saccharomyces cerevisiae Ptp2 and Ptp3, respectively. Although BcPtpA and BcPtpB have opposite functions in conidiation, they are essential for sclerotial formation in B. cinerea. BcPTPA and BcPTPB deletion mutants ΔBcPtpA-10 and ΔBcPtpB-4 showed significantly increased sensitivity to osmotic and oxidative stresses, and to cell wall damaging agents. Inoculation tests showed that both mutants exhibited dramatically decreased virulence on tomato leaves, apples and grapes. In S. cerevisiae, it has been shown that Ptp2 and Ptp3 negatively regulate the high-osmolarity glycerol (HOG pathway and the cell wall integrity (CWI pathway. Although both BcPtpA and BcPtpB were able to inactive Hog1 and Mpk1 in S. cerevisiae, in contrast to S. cerevisiae, they positively regulate phosphorylation of BcSak1 (the homologue of Hog1 and BcBmp3 (the homologue of Mpk1 in B. cinerea under stress conditions. These results demonstrated that functions of PTPs in B. cinerea are different from those in S. cerevisiae, and BcPtpA and BcPtpB play important roles in regulation of vegetative development, virulence and in adaptation to oxidative, osmotic and cell-wall damage stresses in B. cinerea.

Chlorella vulgaris is considered as one of the potential sources of biomass for bio-based products because it consists of large amounts of carbohydrates. In this study, hydrothermal acid hydrolysis with five different acids (hydrochloric acid, nitric acid, peracetic acid, phosphoric acid, and sulfuric acid) was carried out to produce fermentable sugars (glucose, galactose). The hydrothermal acid hydrolysis by hydrochloric acid showed the highest sugar production. C. vulgaris was hydrolyzed with various concentrations of hydrochloric acid [0.5-10 % (w/w)] and microalgal biomass [20-140 g/L (w/v)] at 121 °C for 20 min. Among the concentrations examined, 2 % hydrochloric acid with 100 g/L biomass yielded the highest conversion of carbohydrates (92.5 %) into reducing sugars. The hydrolysate thus produced from C. vulgaris was fermented using the yeast Brettanomyces custersii H1-603 and obtained bioethanol yield of 0.37 g/g of algal sugars.

This study aims to investigate the frequency of fibromyalgia syndrome and to specify fibromyalgia syndrome-associated clinical symptoms in patients with acne vulgaris. Eighty-eight patients (28 males, 60 females; mean age 23.2±5.1 years; range 18 to 40 years) with acne vulgaris and age, sex- and body mass index-similar 76 healthy controls (14 males, 62 females; mean age 24.5±2.9 years; range 18 to 35 years) were included. Acne vulgaris was evaluated by using the Global Acne Scale, while Hospital Anxiety and Depression Scale was used to evaluate anxiety. Fibromyalgia-associated pain, sleep disturbance, anxiety, and menstrual cycle disturbance were significantly more frequent in patients with acne vulgaris than controls. Also, the severity of anxiety and the number of tender points were significantly higher in the acne vulgaris patients than controls. This study indicates that patients with acne vulgaris have increased frequency of fibromyalgia syndrome than healthy controls (21.6% versus 5.3%, respectively).

Full Text Available A pathogenic mutant, BCG183, was obtained by screening the T-DNA insertion library of Botrytis cinerea. A novel pathogenicity-related gene BcKMO, which encodes kynurenine 3-monooxygenase (KMO, was isolated and identified via thermal asymmetric interlaced PCR, bioinformatics analyses, and KMO activity measurement. The mutant BCG183 grew slowly, did not produce conidia and sclerotia, had slender hyphae, and presented enhanced pathogenicity. The phenotype and pathogenicity of the BcKMO-complementing mutant (BCG183/BcKMO were similar to those of the wild-type (WT strain. The activities of polymethylgalacturonase, polygalacturonase, and toxins were significantly higher, whereas acid production was significantly decreased in the mutant BCG183, when compared with those in the WT and BCG183/BcKMO. Moreover, the sensitivity of mutant BCG183 to NaCl and KCl was remarkably increased, whereas that to fluconazole, Congo Red, menadione, H2O2, and SQ22536 and U0126 [cAMP-dependent protein kinase (cAMP and mitogen-activated protein kinase (MAPK signaling pathways inhibitors, respectively] were significantly decreased compared with the other strains. Furthermore, the key genes involved in the cAMP and MAPK signaling pathways, Pka1, Pka2, PkaR, Bcg2, Bcg3, bmp1, and bmp3, were significantly upregulated or downregulated in the mutant BCG183. BcKMO expression levels were also upregulated or downregulated in the RNAi mutants of the key genes involved in the cAMP and MAPK signaling pathways. These findings indicated that BcKMO positively regulates growth and development, but negatively regulates pathogenicity of B. cinerea. Furthermore, BcKMO was found to be involved in controlling cell wall degrading enzymes activity, toxins activity, acid production, and cell wall integrity, and participate in cAMP and MAPK signaling pathways of B. cinerea.

Treatment of vitiligo vulgaris with the combination therapy of topical steroid and vitamin D3 compound

Full Text Available We reported here two cases of vitiligo vulgaris successfully treated with the combination therapy of topical steroid and vitamin D3 compound and currently maintained by vitamin D3 analog without any adverse effects: skin atrophy, striae or telangiectasia on the exposed areas. The best-known mechanism of topical vitamin D3 analog is the enhancement of keratinocytes differentiation and anti-proliferative effects. Vitamin D3 analog is also reported to suppress T-cell mediated immunity, T-cell skin recruitment, and skin infiltration via down-regulating cutaneous lymphocyte antigen expression. Furthermore, vitamin D3 compounds are known to influence melanocyte maturation and differentiation and also to up-regulate melanogenesis. Autoreactive lymphocytes against melanocytes are one of the causes. Topical vitamin D3 analog may control vitiligo itself, however stronger immunosuppressive effects of topical corticosteroid may contribute to rapid re-pigmentation suppressing auto-reactive lymphocytes. The topical combination therapy is a simple, effective and safe option for vitiligo vulgaris in sun-exposed areas.

2018-05-01

As an important sequential work of the S-wave {B}c(* ) ({}1{S}0({}3{S}1) ) meson production at the large hadron electron collider (LHeC), we investigate the production of the P-wave excited {B}c* * states (1 P 1 and 3 P J with J = 0, 1, 2) via photoproduction mechanism within the framework of nonrelativistic QCD at the LHeC. Generally, the {e}-+P\\to γ +g\\to {B}c* * +b+\\bar{c} process is considered as the main production mechanism at an electron–proton collider due to the large luminosity of the gluon. However, according to our experience on the S-wave {B}c(* ) meson production at the LHeC, the extrinsic production mechanism, i.e., {e}-+P\\to γ +c\\to {B}c* * +b and {e}-+P\\to γ +\\bar{b} \\to {B}c* * +\\bar{c}, could also provide dominating contributions at low p T region. A careful treatment between these channels is performed and the results on total and differential cross sections, together with main uncertainties are discussed. Taking the quark masses m b = 4.90 ± 0.40 GeV and m c = 1.50 ± 0.20 GeV into account and summing up all the production channels, we expect to accumulate ({2.48}-1.75+3.55)× {10}4 {B}c* * ({}1{P}1), ({1.14}-0.82+1.49)× {10}4 {B}c* * ({}3{P}0),({2.38}-1.74+3.39)× {10}4 {B}c* * ({}3{P}1) and ({5.59}-3.93+7.84)× {10}4 {B}c* * ({}3{P}2) events at the \\sqrt{S}=1.30 {{T}}{{e}}{{V}} LHeC in one operation year with luminosity { \\mathcal L }={10}33 cm‑2 s‑1. With such sizable events, it is worth studying the properties of excited P-wave {B}c* * states at the LHeC.

Full Text Available The publication is devoted to archaeological research of monuments of the catacomb of Arys culture of Southern Kazakhstan (1st Century B.C. - 3rd Century A.D.. Now scientists have a complete understanding of the range and typology, periodization and chronology of monuments of this culture. There are three stages: Karaultobe (4th century B.C. - 1st century A.D.; Karatobe (1st Century B.C. - 4th century A.D.; Altintobe (4th-6th centuries A.D.. These stages are characterized by specific clusters of signs in the form of artifacts. The author also carried out the ethnic attribution of the Arys culture in association with the ancient state Kangiuj. As a result of this work, the ethnicity of the state Kangiuj was revealed: in particular, late Saka’s, Sarmatian, Huns and Kangiuj ethnic components which are relevant to archaeological complexes, were identified. In the Arys monuments of culture the author discovered complexes of findings which associated with the Sarmatian world of Eurasia by their ethno-cultural parameters. They include typical for the Sarmatians list of ritual action and the funerary equipment, including weapons, bronze mirrors, ritual and religious objects, signs-tamgas, jewelry (including Egyptian faience, articles in “animal”, gold-turquoise and polychrome style. The characteristics of the burial complexes of catacombs of the Arys culture discussed in the publication and corresponding to chronological calculations and ethno-cultural interpretations, allow to speak about presence in the territory of South Kazakhstan of the Asian Sarmatians or any local branch of the Union of the Sarmatian tribes in the 1st century B.C. - 3rd century A.D.

Acne vulgaris is a common inflammatory skin disease. Vitamin D deficiency plays a role in many inflammatory skin diseases. It may play a role in pathogenesis of acne vulgaris. This study aimed to assess serum levels of 25 hydroxy vitamin D in patients with acne vulgaris before and after treatment with isotretinoin and its relation with acne vulgaris severity. Ninety patients with acne vulgaris and 60 age-sex matched healthy subject as controls have been recruited in this study. Patients were treated with 0.75 mg/kg/d isotretinoin for 3 months. Serum level of 25 hydroxy vitamin D has been measured at baseline and after treatment. Serum levels of 25 hydroxy vitamin D were significantly higher in patients with acne vulgaris than healthy controls (P = .001). There was a significant inverse relation between level of 25 hydroxy vitamin D and severity of acne vulgaris before treatment (P = .001). Serum levels of 25 hydroxy vitamin D were significantly increased after isotretinoin treatment in patients with acne vulgaris (P = .001). This study concluded that vitamin D may play a potential role in pathogenesis of acne vulgaris or acne vulgaris may have a negative effect on vitamin D synthesis. Further studies are needed to confirm these potential relations. © 2018 Wiley Periodicals, Inc.
Involvement of indole-3-acetic acid produced by Azospirillum brasilense in accumulating intracellular ammonium in Chlorella vulgaris.

Meza, Beatriz; de-Bashan, Luz E; Bashan, Yoav

2015-01-01

Accumulation of intracellular ammonium and activities of the enzymes glutamine synthetase (GS) and glutamate dehydrogenase (GDH) were measured when the microalgae Chlorella vulgaris was immobilized in alginate with either of two wild type strains of Azospirillum brasilense or their corresponding indole-3-acetic acid (IAA)-attenuated mutants. After 48 h of immobilization, both wild types induced higher levels of intracellular ammonium in the microalgae than their respective mutants; the more IAA produced, the higher the intracellular ammonium accumulated. Accumulation of intracellular ammonium in the cells of C. vulgaris followed application of four levels of exogenous IAA reported for A. brasilense and its IAA-attenuated mutants, which had a similar pattern for the first 24 h. This effect was transient and disappeared after 48 h of incubation. Immobilization of C. vulgaris with any bacteria strain induced higher GS activity. The bacterial strains also had GS activity, comparable to the activity detected in C. vulgaris, but weaker than when immobilized with the bacteria. When net activity was calculated, the wild type always induced higher GS activity than IAA-attenuated mutants. GDH activity in most microalgae/bacteria interactions resembled GS activity. When complementing IAA-attenuated mutants with exogenous IAA, GS activity in co-immobilized cultures matched those of the wild type A. brasilense immobilized with the microalga. Similarity occurred when the net GS activity was measured, and was higher with greater quantities of exogenous IAA. It is proposed that IAA produced by A. brasilense is involved in ammonium uptake and later assimilation by C. vulgaris. Copyright © 2014 Institut Pasteur. Published by Elsevier Masson SAS.

An indirect fluorescent antibody assay (IFA) was developed using Strongylus vulgaris third stage larvae (L3) as antigens. Observations using the IFA indicate that a species-specific antibody response to S. vulgaris L3 develops in S. vulgaris-infected ponies and that some surface L3 antigens are shared by adult worms. Sequential antibody levels against S. vulgaris were measured in strongyle-naive and in immune ponies following initial and challenge infections using the IFA and an indirect hemagglutination assay (IHA). Antibody levels measured by IFA increased faster following initial infections than did levels measured by IHA. Antibody levels appear to increase following challenge infections of immune ponies when measured with the IFA, but not with the IHA. Significant differences in antibody titers were not seen between ponies which developed colic following challenge infections and those that did not develop colic. Antibodies were not detectable in ponies unexposed to larval migrations, but which received surgical implantation of S. vulgaris adults into the cecum.

Strongyle parasites are ubiquitous in grazing horses. Strongylus vulgaris, the most pathogenic of the large strongyles, is known for its extensive migration in the mesenteric arterial system. The lifecycle of S. vulgaris is characterised by a long prepatent period where the migrating larvae are virtually undetectable as there currently is no test available for diagnosing prepatent S. vulgaris infection. Presence of S. vulgaris larvae in the arterial system causes endarteritis and thrombosis with a risk of non-strangulating intestinal infarctions. Emergence of anthelmintic resistance among cyathostomins has led to recommendations of reduced treatment intensity by targeting horses that exceed a predetermined strongyle faecal egg count threshold. One study suggests an apparent increase in prevalence of S. vulgaris on farms where reduced anthelmintic treatment intensity has been implemented. These issues highlight the need for an accurate and reliable assay for diagnosing prepatent S. vulgaris infection. Immunoscreening of a larval S. vulgaris cDNA library using hyperimmune serum raised against S. vulgaris excretory/secretory antigens was performed to identify potential diagnostic antigens. Immunoreactive clones were sequenced, one potential antigen was characterised, expressed as a recombinant protein, initially evaluated by western blot (WB) analysis, the diagnostic potential of the IgG subclasses was evaluated by ELISA, and the diagnostic accuracy evaluated using serum from 102 horses with known S. vulgaris infection status. The clone expressing the potential antigen encoded a S. vulgaris SXP/RAL2 homologue. The recombinant protein, rSvSXP, was shown to be a potential diagnostic antigen by WB analysis, and a target of serum IgGa, IgG(T) and total IgG in naturally infected horses, with IgG(T) antibodies being the most reliable indicator of S. vulgaris infection in horses. Evaluation of diagnostic accuracy of the ELISA resulted in a sensitivity of 73.3%, a specificity

Given their increasingly widespread application, the toxic effects of ionic liquids (ILs) have become the subject of significant attention in recent years. Therefore, the present study assessed the acute toxic effects of 1-alkyl-3-methylimidazolium nitrate ([C n mim]NO 3 (n = 2, 4, 6, 8, 10, 12)) on Chlorella vulgaris and Daphnia magna. The sensitivity of the tested organism Daphnia magna and the investigated IL concentrations in water using high-performance liquid chromatography (HPLC) were also evaluated to demonstrate the reliability of the present study. The results illustrated that Daphnia magna is indeed sensitive to the reference toxicant and the investigated ILs were stable in the aquatic environment. The 50% effect concentration (EC 50 ) was used to represent the acute toxic effects on Chlorella vulgaris and Daphnia magna. With the increasing alkyl-chain lengths, the toxicity of the investigated ILs increased in both the test organisms. Accordingly, the alkyl-chain lengths can cause significantly toxic effects on aquatic organisms, and Daphnia magna are much more sensitive than Chlorella vulgaris to the imidazolium-based ILs used in the present study. Furthermore, the present study provides more information on the acute toxic effects of 1-alkyl-3-methylimidazolium nitrate. Copyright © 2017 Elsevier Ltd. All rights reserved.

Although prior studies have evaluated epidemiologic patterns of acne vulgaris in various ethnicities and regions, adequate understanding of the worldwide burden of the disease associated with patients in their late adolescence (15–19-year olds remains lacking. Objective: To assess the global burden of the disease associated with acne vulgaris for late adolescents (15–19-year olds and provide an overview of the epidemiology, pathophysiology, and treatment options for acne in this population. Design: Database summary study. Setting: Global Burden of Disease Study 2010 database. Participants: Global Burden of Disease regions comprised countries with prevalence of acne vulgaris between the ages of 15 and 19 years. Main outcomes and measures: Geographic region-level disability-adjusted life year rates (per 100,000 persons associated with acne vulgaris in years 1990 through 2010. Median percentage change in disability-adjusted life year rates was estimated for each region across the specified study period. Conclusion and relevance: Acne vulgaris-associated disease burden exhibits global distribution and has continued to grow in prevalence over time within this population. This continued growth suggests an unmet dermatologic need worldwide for this disorder and potential opportunities for improved access and delivery of dermatologic care. Our analysis of the literature reveals numerous

Distorted segregation of the brittle culm-1 gene (bc1) on rice chromosome 3 was found with greatly increased or decreased frequency of bc1 bc1 genotype in inter-subspecific hybrids, although the gene normally transmitted to its offspring following the Mendelian Law in intra-subspecific hybrids. In a combination of Kamairazu//Ketan Nangka/Kamairazu,an increased frequency of bc1 bc1 in F1, normal segregation in F2, and increased and decreased frequency in a few F3 and F4 lines were observed. In a cross of IR36/Kamairazu, decreased frequency in F2, both normal and decreased segregations in F3 and F4, and a few lines of increased ratio in F4 were found. In F2 of Ketan Nangka/IR36//Kamairazu, increased and decreased and normal segregations were all observed. There was no significant correlation between the frequency of bc1 bc1 and pollen fertility. It implied that distorted segregation of bc1 was caused by selective fertilization of male gametes, which were governed by gametophyte genes of ga2, ga3 and ga14 on chromosome 3.

Full Text Available Background. Acne vulgaris is a common skin disease that can adversely affect the quality of life of patients. Objective. The aim of this study was to determine the quality of life in patients with acne vulgaris. Methods. This study was carried out on 70 patients with acne vulgaris (28 males, 42 females. All the patients filled out two Persian versions of questionnaires: short form 36 (SF-36 and Dermatology Life Quality Index (DLQI. The obtained data were analyzed by using SPSS software (version 17. Results. The scores for physical functioning, social functioning, and bodily pain domains in patients were over 70%, but the scores for role physical, general health, vitality, role emotional, and mental health in patients were under 70%. Scores on the DLQI in patients with acne vulgaris ranged from 0 to 22 (mean ± SD, 8.18 ± 4.83. After comparing mean score of DLQI with respect to gender and age, it was found that the difference between the two groups was not statistically significant. Conclusion. Acne vulgaris has a significant effect on the quality of life. There was not any significant gender or age related difference in QOL.

Full Text Available Three patients with severe acne vulgaris, not responding with long courses of doxycycline, minocycline and erythromycin were given oral clarithromycin in pulsed regimen. The patients were given 7 days course of clarithromycin 250mg twice daily, which was repeated after a gap of 10 days. Such 3 courses were given. The lesions responded significantly. No significant side effect was noted. Pulse clarithromycin therapy seems to be a good alternative and effective tool in the management of severe acne vulgaris.

A 1.35 Å resolution crystal structure of Cas2 from the bacterium Desulfovibrio vulgaris (DvuCas2) is reported. CRISPRs (clustered regularly interspaced short palindromic repeats) provide bacteria and archaea with RNA-guided acquired immunity to invasive DNAs. CRISPR-associated (Cas) proteins carry out the immune effector functions. Cas2 is a universal component of the CRISPR system. Here, a 1.35 Å resolution crystal structure of Cas2 from the bacterium Desulfovibrio vulgaris (DvuCas2) is reported. DvuCas2 is a homodimer, with each protomer consisting of an N-terminal βαββαβ ferredoxin fold (amino acids 1–78) to which is appended a C-terminal segment (amino acids 79–102) that includes a short 3{sub 10}-helix and a fifth β-strand. The β5 strands align with the β4 strands of the opposite protomers, resulting in two five-stranded antiparallel β-sheets that form a sandwich at the dimer interface. The DvuCas2 dimer is stabilized by a distinctive network of hydrophilic cross-protomer side-chain interactions.

Objective was to evaluate effectiveness of 2% tea lotion in comparisonwith 5% zinc sulphate solution in the treatment of acne vulgaris. This is asingle-blind randomly comparative therapeutic clinical trial carried out inthe Department of Dermatology, Baghdad Teaching Hospital, Iraq from June 2006to December 2007. Full history and clinical examination were studied for eachpatient regarding all relevant points of the disease, to evaluate theseverity of acne. Forty-seven patients with acne vulgaris were dividedrandomly into 2 groups and were instructed to use the following solutionstwice daily for 2 months; group A used 2% tea lotion, group B used 5% zincsulphate lotion. Patients with papulopustular lesions were included in thestudy, while patients with severe acne were excluded. The clinicalimprovement was scored by counting the number of inflammatory lesions beforeand after treatment. Forty patients completed the study, their ages rangedfrom 13-27 years with a mean+-standard deviation of 19.5+-3.5 years with 20patients in each group. Two percent tea lotion was statistically significantin decreasing the number of the inflammatory lesions in acne vulgaris, while5% zinc sulphate solution was beneficial, but did not reach statisticallysignificant level as tea lotion. Two percent of tea lotion was a goodalternative remedy to be used in the treatment of acne vulgaris and was muchsuperior than topical 5% zinc sulphate solution. (author)
BC Hydro shops for GHG offsets

BC Hydro is reported to have offered to purchase one million tonnes of carbon dioxide reductions in Canada's Greenhouse Gas Emissions Reduction Trading program (GERT). The program uses a baseline and credit system, where emitters purchase measurable quantities of site-specific GHG reductions. Since mid-1998, the program registered five bilateral trades and seven offers to sell. BC Hydro's recent offer is the first offer to buy. BC Hydro has made the offer to buy in expectation of the introduction of the start of the Kyoto Protocol reductions, and expects to be in the game for some time to come if it is to meet its obligations under the Kyoto Protocol. Preference will be given to projects located in Canada, but BC Hydro will consider reductions created anywhere in the world. The financial range of a single trade is between $50,000 and $1 million. (GHG offsets are currently trading in North America for between $.50 and $3.00 Cdn per metric tonne of carbon dioxide equivalent.) At present, offsets are selling at a heavily discounted price because of the uncertainty that investments made now will be credited against future regulations curbing emitters. Consequently, buying now while prices are low, may lead to sizable benefits later, depending on the actual regulations when they are promulgated. Trading now will also give BC Hydro greater credibility and assurance to have its voice heard when discussions about emissions trading and the implementation of emission trading rules reaches the serious stage
Description of Phaseolus vulgaris L. aborting embryos from ethyl methanesulfonate (EMS mutagenized plants

Directory of Open Access Journals (Sweden)

Silué, S.

2013-01-01

Full Text Available The aim of this study was to describe the embryos abortion process and the inheritance of the embryos abortion trait in Phaseolus vulgaris plants deficient in seed development. These plants were isolated within the second generation of an ethyl methanesulfonate (EMS TILLING population of P. vulgaris cv. 'BAT93'. Mutant embryos show abnormalities mainly in suspensors, shoot apical meristem (SAM and cotyledons from the globular to the cotyledon stages and abort before maturity compared to those observed in wild-type samples. Mutant embryos show also hyperhydricity and contain low amount of chlorophyll. Genetic analyses of F1, F2 and F3 populations from the crosses carried out between the mutagenized plants with aborting embryos and the wild-type plants indicated that the embryo abortion phenotype is maternally inherited and controlled by a single recessive gene. These Phaseolus mutant plants with aborting embryos constitute a valuable material for plant embryogenesis studies.
Pemphigus Vulgaris with Solitary Toxic Thyroid Nodule

Full Text Available Background. Pemphigus vulgaris is an autoimmune vesiculobullous disease, affecting the skin and mucous membranes. It is reported to be associated with other autoimmune diseases including autoimmune thyroid diseases. However we report herein a case of pemphigus vulgaris associated with autonomous toxic nodule. Case Presentation. A 51-year-old woman was evaluated for blisters and erosions that develop on her trunk, face, and extremities, with a five-year history of progressively enlarging neck mass, and a past medical history of pemphigus vulgaris seven years ago. The condition was associated with palpitation, dyspnea, and heat intolerance. Thyroid function tests and thyroid scan were compatible with the diagnosis of thyrotoxicosis due to autonomous toxic nodule. Exacerbation of pemphigus vulgaris was proved by skin biopsy from the patient which revealed histologic picture of pemphigus vulgaris. Conclusion. Autoimmune thyroid diseases are reported to associate pemphigus vulgaris. To our knowledge, this case is the first in the English literature to report association between pemphigus vulgaris and autonomous toxic nodule and highlights the possibility of occurrence of pemphigus vulgaris with a nonautoimmune thyroid disease raising the question: is it just a coincidence or is there an explanation for the occurrence of both conditions together?

Bailey, M; Martin, S C; Lloyd, S

1989-08-01

Immunologic and hematologic responses were examined in 4 ponies with experimentally induced Strongylus vulgaris infection and in 5 helminth-free ponies. Two ponies were inoculated with 200 larvae and 2 were inoculated with 700 larvae of S vulgaris and then were reinoculated with the same numbers of larvae 34 weeks later. Initial response of the ponies inoculated with S vulgaris was S vulgaris antigen-induced lymphocyte response that developed 1.5 to 3 weeks after inoculation and did not persist. Development of antigen-reactive lymphocytes was followed sequentially by a biphasic complement-fixing antibody response, then biphasic eosinophilia. Antibody titer to S vulgaris antigen was higher in ponies inoculated with 700 larvae, compared with that in ponies given 200 larvae of S vulgaris. Also, the second peak in antibody titer and in absolute number of eosinophils was observed earlier in ponies inoculated with 700 larvae, compared with ponies inoculated with 200 S vulgaris larvae, and subsided before or from about 24 weeks after inoculation. The prepatent period for S vulgaris infection was 24 to 25 weeks. After reinoculation with S vulgaris, a degree of increased lymphocyte responsiveness was apparent but, by 17 weeks after reinoculation, only the primary peak in the absolute number of eosinophils indicated an anamnestic response. Essentially, antibody was not detectable after reinoculation.
Bacterial Cellulose (BC) as a Functional Nanocomposite Biomaterial

compressive tests. In our second study, we developed a one-pot in-situ biosynthetic method to fabricate structurally controllable bacterial cellulose (BC)/reduced graphene oxide (RGO) composites. The graphene oxide (GO) was highly reduced during a standard autoclave process using a traditional mannitol culture medium as the reducing agent. The electrical conductivity of the RGO was found to be 23.75 S m-1. The final BC/RGO composites were developed in three distinct forms: 1) sealed structures in the water, 2) aerogels characterized by a porous cross section and aligned longitudinal structure, and 3) films embedded within the RGO sheets. Because of the simplicity and non-toxic nature of this work, it can be used in biomedical and bioelectronics applications. The last study was on dye degradation using BC as the substrate. The surface of the BC was chemically oxidized to produce aldehyde groups to successfully covalently crosslink laccase. TiO2 and laccase (Lac) were co-immobilized on the surface of OBC and the dye degradation process was carried out under specific conditions. Compared with free laccase, the optimum pH of the immobilized laccase system shifted to lower pH, while the optimum temperature decreased from 55 °C to 50 °C. The dye degradation experiments showed that the optimum pH for dye degradation was pH 5.0-6.0, while the optimum temperature was ca. 40 ºC. Under UV illumination, the dye degradation efficiency significantly improved characteristic of a synergy in the system. This dissertation contributes to the basic research of bacterial cellulose which will result in novel ideas that can possibly result in future industrial applications. The research provides a fundamental underpinning of specialized structure-property relationships between BC and the materials used to fabricate the BC nanocomposites that have value-added applications that are environmentally safe and eco-friendly.

The Integrative Experimental System (IES) was established as a tool to evaluate the rela-tionship of the subsystems in Bioregenerative Life Support System, and Multibiological Life Support System Experiments (MLSSE) have been conducted in the IES. The IES consists of a higher plant chamber, an animal chamber and a plate photo bioreactor (PPB) which cultivated lettuce (Lactuca sativa L.), silkworm (Bombyx Mori L.) and microalgae (Chlorella vulgaris), respectively. In MLSSE, four volunteers took turns breathing the system air through a tube connected with the animal chamber periodically. According to the CO2 concentration in the IES, the automotive control system of the PPB changed the light intensity regulating the photosynthesis of Chlorella vulgaris to make CO2 /O2 in the system maintain at stable levels. Chlorella vulgaris grew with human urine by carrying certain amount of alga liquid out of the bioreactor every day with synthetic urine replenished into the system, and O2 was regenerated, at the same time human urine was purified. Results showed that this IES worked stably and Chlorella vulgaris grew well; The culture of Chlorella vulgaris could be used to keep the balance of CO2 and O2 , and the change of light intensity could control the gas composition in the IES; Microalgae culture could be used in emergency in the system, the culture of Chlorella vulgaris could recover to original state in 5 days; 15.6 ml of condensation water was obtained every day by the culture of Chlorella vulgaris; The removal efficiencies of N, P in human urine could reach to 98.2% and 99.5%.

Black carbon (BC) is an anthropogenic aerosol from fossil fuels, and biomass burning. It absorbs solar radiation, and heats the atmosphere leading 0.4W m-2 radiative forcing. BC is a particle that can cause serious effects on human body as well. Toxicological studies of black carbon suggests that BC may be an important carrier of toxic chemicals to human body. The recent researches show that one of the main precursor of BC is vehicle emission, but the inventory of BC emission rate from vehicle is inadequate in South Korea. This study tries to find differences of BC emission from different sizes of vehicles using different types of fuels. Fuels used in vehicles are gasoline, liquefied petroleum gas (LPG), and diesel. BC was directly measured from the tail pipe of vehicles using Aethalometer (AE33, Magee Scientific Corporation). This study was conducted in Transport Pollutant Research Center, National Institute of Environmental Research, South Korea. Measurement was progressed with the five different test modes of speeds. Speed modes includes 4.7, 17.3, 34.1, 65.4, and 97.3 km h-1. Emission rate of BC was high in the slowest speed mode, and showed decrease with increase of the speed of vehicles. Gasoline vehicles had the relatively higher emission rate of BC than the LPG vehicle, while the emission rate of BC for Diesel with DPF (Diesel Particle Filter) was observed to be the lowest.

OBJECTIVES: The aim of this study was to determine the antiproliferative and apoptotic effects of hot water extracts of Chlorella vulgaris on hepatoma cell line HepG2. INTRODUCTION: The search for food and spices that can induce apoptosis in cancer cells has been a major study interest in the last decade. Chlorella vulgaris, a unicellular green algae, has been reported to have antioxidant and anti‐cancer properties. However, its chemopreventive effects in inhibiting the growth of cancer cells have not been studied in great detail. METHODS: HepG2 liver cancer cells and WRL68 normal liver cells were treated with various concentrations (0‐4 mg/ml) of hot water extract of C. vulgaris after 24 hours incubation. Apoptosis rate was evaluated by TUNEL assay while DNA damage was assessed by Comet assay. Apoptosis proteins were evaluated by Western blot analysis. RESULTS: Chlorella vulgaris decreased the number of viable HepG2 cells in a dose dependent manner (p Chlorella vulgaris tested. Evaluation of apoptosis by TUNEL assay showed that Chlorella vulgaris induced a higher apoptotic rate (70%) in HepG2 cells compared to normal liver cells, WRL68 (15%). Western blot analysis showed increased expression of pro‐ apoptotic proteins P53, Bax and caspase‐3 in the HepG2 cells compared to normal liver cells WRL68, and decreased expression of the anti‐apoptotic protein Bcl‐2. CONCLUSIONS: Chlorella vulgaris may have anti‐cancer effects by inducing apoptosis signaling cascades via an increased expression of P53, Bax and caspase‐3 proteins and through a reduction of Bcl‐2 protein, which subsequently lead to increased DNA damage and apoptosis.

In higher eukaryotes, increasing evidence suggests, gene expression is to a large degree controlled by RNA. Regulatory RNAs have been implicated in the management of neuronal function and plasticity in mammalian brains. However, much of the molecular-mechanistic framework that enables neuronal regulatory RNAs to control gene expression remains poorly understood. Here, we establish molecular mechanisms that underlie the regulatory capacity of neuronal BC RNAs in the translational control of gene expression. We report that regulatory BC RNAs employ a two-pronged approach in translational control. One of two distinct repression mechanisms is mediated by C-loop motifs in BC RNA 3′ stem-loop domains. These C-loops bind to eIF4B and prevent the factor's interaction with 18S rRNA of the small ribosomal subunit. In the second mechanism, the central A-rich domains of BC RNAs target eIF4A, specifically inhibiting its RNA helicase activity. Thus, BC RNAs repress translation initiation in a bimodal mechanistic approach. As BC RNA functionality has evolved independently in rodent and primate lineages, our data suggest that BC RNA translational control was necessitated and implemented during mammalian phylogenetic development of complex neural systems.

The purpose of this study was to assess the sonographic morphology of the clinical and subclinical pathology of facial acne vulgaris. We studied patients with facial acne vulgaris diagnosed by certified dermatologists, and using a standardized protocol for sonographic examinations, we sequentially described the sonographic pathomorphologic characteristics. Lesions of particular interest to the referring clinician were also analyzed separately. Additionally, acne involvement was staged clinically and sonographically (SOS-Acne) using morphologic definitions of the relevant lesions and predefined scoring systems for gradation of the severity of acne lesions. A total of 245 acne lesions in 20 consecutive patients were studied. Sonographic abnormalities consisted of pseudocysts, folliculitis, fistulas, and calcinosis. Most conditions were subclinical and mostly due to lesion extensions deep into the dermis and hypodermis (52% of pseudocysts and 68% of fistulas). The statistical concordance between acne severity scores assigned by two separate clinicians was strong (κ = 0.8020), but the corresponding sonographic scores generally showed more severe and clinically occult involvement. Facial acne vulgaris often involves deeper tissues, beyond the reach of the spatially restricted clinical examination; these subclinical conditions can be detected and defined with sonography. Additionally, acne vulgaris is amenable to sonographic scoring.

MADS-box genes form a large gene family in plants and are involved in multiple biological processes, such as flowering. However, the regulation mechanism of MADS-box genes in flowering remains unresolved, especially under short-term cold conditions. In the present study, we isolated BcMAF1 , a Pak-choi ( Brassica rapa ssp. Chinensis ) MADS AFFECTING FLOWERING ( MAF ), as a floral repressor and functionally characterized BcMAF1 in Arabidopsis and Pak-choi. Subcellular localization and sequence analysis indicated that BcMAF1 was a nuclear protein and contained a conserved MADS-box domain. Expression analysis revealed that BcMAF1 had higher expression levels in leaves, stems, and petals, and could be induced by short-term cold conditions in Pak-choi. Overexpressing BcMAF1 in Arabidopsis showed that BcMAF1 had a negative function in regulating flowering, which was further confirmed by silencing endogenous BcMAF1 in Pak-choi. In addition, qPCR results showed that AtAP3 expression was reduced and AtMAF2 expression was induced in BcMAF1 -overexpressing Arabidopsis . Meanwhile, BcAP3 transcript was up-regulated and BcMAF2 transcript was down-regulated in BcMAF1 -silencing Pak-choi. Yeast one-hybrid and dual luciferase transient assays showed that BcMAF1 could bind to the promoters of BcAP3 and BcMAF2 . These results indicated that BcAP3 and BcMAF2 might be the targets of BcMAF1. Taken together, our results suggested that BcMAF1 could negatively regulate flowering by directly activating BcMAF2 and repressing BcAP3 .
Ichthyosis vulgaris: the filaggrin mutation disease.

Ichthyosis vulgaris is caused by loss-of-function mutations in the filaggrin gene (FLG) and is characterized clinically by xerosis, scaling, keratosis pilaris, palmar and plantar hyperlinearity, and a strong association with atopic disorders. According to the published studies presented in this review article, FLG mutations are observed in approximately 7·7% of Europeans and 3·0% of Asians, but appear to be infrequent in darker-skinned populations. This clinical review article provides an overview of ichthyosis vulgaris epidemiology, related disorders and pathomechanisms. Not only does ichthyosis vulgaris possess a wide clinical spectrum, recent studies suggest that carriers of FLG mutations may have a generally altered risk of developing common diseases, even beyond atopic disorders. Mechanistic studies have shown increased penetration of allergens and chemicals in filaggrin-deficient skin, and epidemiological studies have found higher levels of hand eczema, irritant contact dermatitis, nickel sensitization and serum vitamin D levels. When relevant, individuals should be informed about an increased risk of developing dermatitis when repeatedly or continuously exposed to nickel or irritants. Moreover, with our current knowledge, individuals with ichthyosis vulgaris should be protected against neonatal exposure to cats to prevent atopic dermatitis and should abstain from smoking to prevent asthma. Finally, they should be advised against excessive exposure to factors that decrease skin barrier functions and increase the risk of atopic dermatitis. © 2013 The Authors.

We report the first evidence for a fully reconstructed decay mode of the B(c)+- meson in the channel B(c)+- --> J/psi pi+-, with J/psi --> mu+ mu-. The analysis is based on an integrated luminosity of 360 pb(-1) in pp collisions at 1.96 TeV center of mass energy collected by the Collider Detector at Fermilab. We observe 14.6 +/- 4.6 signal events with a background of 7.1 +/- 0.9 events, and a fit to the J/psi pi+-mass spectrum yields a B(c)+- mass of 6285.7 +/- 5.3(stat) +/- 1.2(syst) MeV/c2. The probability of a peak of this magnitude occurring by random fluctuation in the search region is estimated as 0.012%.

Highlights: ► The reaction of phase Al 3 BC with Ti was investigated. ► The transformation leads to the formation of C-doped TiB 2 and B-doped TiC. ► The doped particles show macroporous and lamellar morphologies. ► A model was proposed to illustrate the transformation mechanism. ► Grain refinement performance of the Al–5Ti–0.8B–0.2C on A356 alloy is excellent. -- Abstract: An Al–8B–2C master alloy was added into Al–Ti melts to study the reaction of Al 3 BC phase with Ti. As a result, a new Al–5Ti–0.8B–0.2C master alloy was fabricated. The microstructures were studied by field emission scanning electron microscope (FESEM), X-ray diffraction (XRD) and transmission electron microscope (TEM). The analysis indicates that C-doped TiB 2 and B-doped TiC which show macroporous and lamellar morphologies are transformed from Al 3 BC. The transformation mechanism is also discussed in this work. Furthermore, the grain refinement performance of the Al–5Ti–0.8B–0.2C on A356 alloy was investigated

Androgens and insulin may contribute to increased sebum production in the pathogenesis of acne vulgaris. We investigated the association between serum desnutrin levels and acne vulgaris in the pathogenesis of insulin resistance. 25 patients presenting with acne vulgaris and 25 control subjects participated in this study. Fasting blood glucose, triglycerides, LDL, VLDL, HDL, total cholesterol, insulin, C-peptide and thyroid function tests were measured. The homeostasis model assessment of insulin resistance (HOMA-IR) was used to calculate insulin resistance. Desnutrin levels were determined by enzyme-linked immunosorbent assay (ELISA) according to the manufacturer's protocol. Patients with acne vulgaris had a mean serum desnutrin level of (8.83 ± 1.13 μIU/mL), which was statistically significantly lower in the control group (10:58 ± 3.43 μIU/mL). In patients with acne vulgaris the serum glucose levels, insulin levels and HOMA-IR values (87.92 ± 7:46 mg/dL, 11.33 ± 5.93 μIU/mL, 2.49 ± 1.40, respectively) were significantly higher than the control group (77.36 ± 9.83 mg/dL, 5.82 ± 2.68 μIU/mL, 1.11 ± 0.51, respectively) (p = 0.01, pacne vulgaris, as a result of increased levels of serum glucose and insulin, the function of desnutrin was suppressed, perhaps contributing to insulin resistance.

In this work, a bacterial cellulose/polyacrylamide (BC/PAM) double network composite was prepared to act as the template for in situ synthesis of silver nanoparticles (AgNPs). Effects of reaction conditions of the BC/PAM composite were investigated on its microstructure, mechanical properties and thermal stabilities. Both the BC/PAM composite and pure BC were utilized to prepare the corresponding silver impregnated nanocomposites, i.e., BC/PAM-AgNPs and BC-AgNPs, by an environmental friendly method, UV irradiation. The influences of the templates were investigated on the AgNPs formation and the antibacterial activities of the nanocomposites by both the zone of inhibition and dynamic shake flask methods. It was shown that the BC/PAM composite displayed a denser microstructure and higher thermal stabilities than pure BC. The BC/PAM-AgNPs nanocomposite exhibited a bigger particle size and lower mass content of AgNPs than the BC-AgNPs one. For the antibacterial test, two nanocomposites exhibited a close antibacterial effect, with a high log reduction above 3 and killing ratio above 99.9%, respectively. Copyright © 2014 Elsevier Ltd.

We previously suggested that insulin increases diacylglycerol (DAG) in BC3H-1 myocytes, both by increases in synthesis de novo of phosphatidic acid (PA) and by hydrolysis of non-inositol-containing phospholipids, such as phosphatidylcholine (PC) and phosphatidylethanolamine (PE). We have now evaluated these insulin effects more thoroughly, and several potential mechanisms for their induction. In studies of the effect on PA synthesis de novo, insulin stimulated [2-3H]glycerol incorporation into PA, DAG, PC/PE and total glycerolipids of BC3H-1 myocytes, regardless of whether insulin was added simultaneously with, or after 2 h or 3 or 10 days of prelabelling with, [2-3H]glycerol. In prelabelled cells, time-related changes in [2-3H]glycerol labelling of DAG correlated well with increases in DAG content: both were maximal in 30-60 s and persisted for 20-30 min. [2-3H]Glycerol labelling of glycerol 3-phosphate, on the other hand, was decreased by insulin, presumably reflecting increased utilization for PA synthesis. Glycerol 3-phosphate concentrations were 0.36 and 0.38 mM before and 1 min after insulin treatment, and insulin effects could not be explained by increases in glycerol 3-phosphate specific radioactivity. In addition to that of [2-3H]glycerol, insulin increased [U-14C]glucose and [1,2,3-3H]glycerol incorporation into DAG and other glycerolipids. Effects of insulin on [2-3H]glycerol incorporation into DAG and other glycerolipids were half-maximal and maximal at 2 nM- and 20 nM-insulin respectively, and were not dependent on glucose concentration in the medium, extracellular Ca2+ or protein synthesis. Despite good correlation between [3H]DAG and DAG content, calculated increases in DAG content from glycerol 3-phosphate specific radioactivity (i.e. via the pathway of PA synthesis de novo) could account for only 15-30% of the observed increases in DAG content. In addition to increases in [3H]glycerol labelling of PC/PE, insulin rapidly (within 30 s) increased PC

Acne vulgaris is one of the most common dermatologic condition especially among adolescents. Acne is related to excess sebum production by sebaceous glands, inflammation both within and adjacent to the comedones, hyperproliferation of Propionibacterium acnes. Some of investigations show association between acne and diet. Milk increases the level of IGF-1 leading to the synthesis of androgen-mediated increases sebum production. Chocolate predispose to hyperglycemia and insulinemia which aggravate of acne vulgaris. High levels of omega-6 fatty acids have been associated with increase of acne in contrast to omega-3 fatty acids, which decrease inflammation. Food have huge impact on development and severity of acne and may exert beneficial effect in the treatment of this disorder.

The effects of pertussis toxin (PT) treatment on insulin-stimulated myristoyl-diacylglycerol (DAG) generation, hexose transport, and thymidine incorporation were studied in differentiated BC3H-1 mycocytes. Insulin treatment caused a biphasic increase in myristoyl-DAG production which was abolished in myocytes treated with PT. There was no effect of PT treatment on basal (nonstimulated) myristoyl-DAG production. Insulin-stimulated hydrolysis of a membrane phosphatidylinositol glycan was blocked by PT treatment. ADP-ribosylation of BC3H-1 plasma membranes with [ 32 P]NAD revealed a 40-kDa protein as the major PT substrate in vivo and in vitro. The time course and dose dependence of the effects of PT on diacylglycerol generation correlated with the in vivo ADP-ribosylation of the 40-kDa substrate. Pertussis toxin treatment resulted in a 71% attenuation of insulin-stimulated hexose uptake without effect on either basal or phorbol ester-stimulated uptake. The stimulatory effects of insulin and fetal calf serum on [ 3 H]thymidine incorporation into quiescent myocytes were attenuated by 61 and 59%, respectively, when PT was added coincidently with the growth factors. Nonstimulated and EGF-stimulated [ 3 H]thymidine incorporation was unaffected by PT treatment. These data suggest that a PT-sensitive G protein is involved in the cellular signaling mechanisms of insulin

The difference in total widths between the $B_c^+$ and $B^+$ mesons is measured using 3.0fb$^{-1}$ of data collected by the LHCb experiment in 7 and 8 TeV centre-of-mass energy proton-proton collisions at the LHC. Through the study of the time evolution of $B_c^+ \\rightarrow J/\\psi \\pi^+$ and $B^+\\rightarrow J/\\psi K^+$ decays, the width difference is measured to be $ \\Delta\\Gamma \\equiv \\Gamma_{B_c^+} - \\Gamma_{B^+} = 4.46 \\pm 0.14 \\pm 0.07mm^{-1}c,$ where the first uncertainty is statistical and the second systematic. The known lifetime of the $B^+$ meson is used to convert this to a precise measurement of the $B_c^+$ lifetime, $\\tau_{B_c^+} = 513.4 \\pm 11.0 \\pm 5.7fs,$ where the first uncertainty is statistical and the second systematic.

The authors studied the characteristics of the leukotriene (LT) C 4 and D 4 receptors on a cultured smooth muscle cell line, BC3H-1. Specific [ 3 H]LTC 4 binding to the cell membrane was greater than 80% of total binding and saturable at a density of 3.96 +/- 0.39 pmol/mg protein, with an apparent dissociation constant(Kd) of 14.3 +/- 2.0 nM (n=9). The association and dissociation of [ 3 H]LTC 4 binding were rapid and apparent equilibrium conditions were established within 5 min. Calculated Kd value of [ 3 H]LTC binding from the kinetic analysis was 9.9 nM. From the competition analysis, calculated Ki value of unlabeled LTC 4 to compete for the specific binding of [ 3 H]LTC 4 was 9.2 nM and was in good agreement with the Kd value obtained from the Scatchard plots or kinetic analysis. The maximum number of binding sites (Bmax) of [ 3 H]LTD 4 in the membrane of BC3H-1 cell line was about 11 times lower than that of the [ 3 H]LTC 4 . The calculated values of Kd and Bmax of [ 3 H]LTD 4 binding were 9.3 +/- 0.8 nM and 0.37 +/- 0.04 pmol/mg proteins, respectively (n=3). These findings demonstrate that BC3H-1 cell line possess both LTC 4 and LTD 4 receptors with a predominance of LTC 4 receptors. Thus, BC3H-1 cell line is a good model to study the regulation of LTC 4 and LTD 4 receptors. 34 references, 5 figures, 1 table
Foraging Behavior Interactions Between Two non-Native Social Wasps, Vespula germanica and V. vulgaris (Hymenoptera: Vespidae): Implications for Invasion Success?

Vespula vulgaris is an invasive scavenging social wasp that has very recently arrived in Patagonia (Argentina), a territory previously invaded - 35 yrs earlier - by another wasp, Vespula germanica Although V. vulgaris wasps possess features that could be instrumental in overcoming obstacles through several invasion stages, the presence of preestablished populations of V. germanica could affect their success. We studied the potential role played by V. germanica on the subsequent invasion process of V. vulgaris wasps in Patagonia by focusing on the foraging interaction between both species. This is because food searching and exploitation are likely to overlap strongly among Vespula wasps. We carried out choice tests where two types of baits were presented in a pairwise manner. We found experimental evidence supporting the hypothesis that V. germanica and V. vulgaris have an asymmetrical response to baits with stimuli simulating the presence of each other. V. germanica avoided baits with either visual or olfactory cues indicating the V. vulgaris presence. However, V. vulgaris showed no preference between baits with or lacking V. germanica stimuli. These results suggest that the presence of an established population of V. germanica may not contribute to added biotic resistance to V. vulgaris invasion. © The Author 2016.

We present a measurement of the Bc+ meson lifetime in the decay mode Bc+ --> J/Psie+nue using the Collider Detector at Fermilab II detector at the Fermilab Tevatron Collider. From a sample of about of 360 pb(-1) of pp collisions at square root of s = 1.96 TeV, we reconstruct J/Psie+ pairs with invariant mass in the kinematically allowed range 4< M(J/Psie) < 6 GeV/c2. A fit to the decay-length distribution of 238 signal events yields a measured Bc+ meson lifetime of 0.463(-0.065)(+0.073)(stat) +/- 0.036(syst) ps.

2016-05-01

Acne vulgaris is a chronic dermatologic complaint with a multifactorial cause. Traditionally, antibiotics and retinoids have been used to manage the condition; patient compliance has been an ongoing issue. A variety of energy-based devices have been reported to be effective in the treatment of acne vulgaris. To review and summarize the current literature specific to treatment of acne vulgaris with energy-based devices. A review of the current literature of energy-based devices used for the treatment of acne vulgaris. Although limited randomized controlled trials for the treatment of acne have been performed, significant clinical improvement of acne vulgaris, especially of inflammatory lesions, has been demonstrated with a variety of energy-based devices. Newer approaches may lead to even better results.
Role of the eosinophil in serum-mediated adherence of equine leukocytes to infective larvae of Strongylus vulgaris.

Klei, T R; Chapman, M R; Dennis, V A

1992-06-01

The adherence of equine leukocytes to Strongylus vulgaris infective larvae (L3) in the presence of normal and immune sera was examined in vitro. Immune sera promoted adherence of buffy coat cells from ponies with S. vulgaris-induced eosinophilia (eosinophilic ponies) to S. vulgaris L3. However, eosinophils in the buffy coat cells were the predominant adherent cell type. Studies using leukocyte populations enriched for eosinophils, neutrophils, and mononuclear cells from eosinophilic ponies support the observations using buffy coat cells that eosinophils were the main effector cells. Adherent eosinophils from eosinophilic ponies immobilized L3. Neutrophils were less adherent and did not immobilize L3. Mononuclear cells failed to adhere. Normal eosinophils from strongly-naive ponies did not immobilize S. vulgaris L3 in the presence of immune serum, suggesting the in vivo activation of eosinophils in eosinophilic animals. Immune serum promoted less adherence of buffy coat cells to Strongylus edentatus or mixed species of Cyathostominae L3, suggesting that the serum-mediated cellular adherence phenomenon was species-specific. Normal serum promoted less cellular adherence to S. vulgaris L3 than immune serum. The adherence mediated by normal serum was removed by heat inactivation, suggesting that this nonspecific phenomenon was a complement-mediated reaction. Immune globulins promoted reactions similar to that seen using heat-inactivated immune serum, whereas normal globulins did not promote adherence. Immune globulins absorbed with pieces of S. vulgaris adult worms did not promote the adherence of buffy coat cells to S. vulgaris L3, suggesting that adult and L3 stages share antigens important in this phenomenon that resulted in the removal of specific adherence antibody during absorption.

The response of exponentially growing Desulfovibrio vulgarisHildenborough to pH 10 stress was studied using oligonucleotidemicroarrays and a study set of mutants with genes suggested by microarraydata to be involved in the alkaline stress response deleted. The datashowed that the response of D. vulgaris to increased pH is generallysimilar to that of Escherichia coli but is apparently controlled byunique regulatory circuits since the alternative sigma factors (sigma Sand sigma E) contributing to this stress response in E. coli appear to beabsent in D. vulgaris. Genes previously reported to be up-regulated in E.coli were up-regulated in D. vulgaris; these genes included three ATPasegenes and a tryptophan synthase gene. Transcription of chaperone andprotease genes (encoding ATP-dependent Clp and La proteases and DnaK) wasalso elevated in D. vulgaris. As in E. coli, genes involved in flagellumsynthesis were down-regulated. The transcriptional data also identifiedregulators, distinct from sigma S and sigma E, that are likely part of aD. vulgaris Hildenborough-specific stress response system.Characterization of a study set of mutants with genes implicated inalkaline stress response deleted confirmed that there was protectiveinvolvement of the sodium/proton antiporter NhaC-2, tryptophanase A, andtwo putative regulators/histidine kinases (DVU0331 andDVU2580).

The potentially severe side effects of systemic corticosteroids and immunosuppressants used in Pemphigus vulgaris (PV) call for novel therapeutic approaches. In this context, pharmacological inhibition of major pathogenic signalling effectors represents a promising alternative. However, we have also shown that overinhibition of effectors required for epidermal homeostasis can exacerbate PV pathophysiology implicating transepidermal keratinocyte fragility. A feedforward target validation therefore preferentially includes studies on knockout mouse models. We previously reported on successful amelioration of PV blisters following inhibition of non-apoptotic, low-level caspase-3. Here, we use conditional, keratinocyte-specific caspase-3-deficient mice (casp3 EKO ) to demonstrate (i) absence of keratinocyte fragility upon injection of the potent Dsg3-specific antibody AK23 and (ii) amelioration of blistering on the background of known signalling effectors. Our results provide the experimental proof of concept justifying translation of the caspase-3 inhibitor approach into PV clinical trials. © 2017 John Wiley & Sons A/S.

Pemphigus vulgaris is an autoimmune disease mediated by auto-antibodies against desmoglein 1 and 3. First line treatment for pemphigus consists of systemic corticosteroids and anti-CD20 therapy (rituximab) to eliminate B-cells. Since 2005, more than 100 patients with pemphigus have been treated with

Involvement in pemphigus vulgaris of the female genital tract including the vulva, vagina and cervix has previously been described. In all these cases other cutaneous and mucosal sites have also been affected at some time. We describe a case of pemphigus vulgaris which only involved the vaginal mucosa. The patient presented with a persistent vaginal discharge and examination showed extensive vaginal erosions. Histology of vaginal biopsies was non-diagnostic. The recognition that the vaginal changes may represent an immunobullous disease led to further vaginal biopsies on which direct immunofluorescence studies were performed. These biopsies showed IgG and C3 in the intercellular epidermis, suggesting a diagnosis of pemphigus vulgaris. During the 3-year period that the patient has been under review there have never been any other cutaneous or mucosal lesions. To our knowledge, this is the first case of pemphigus vulgaris localized exclusively to the vaginal mucosa. There was considerable delay in diagnosis and this case highlights how important it is to recognize that chronic mucosal lesions at genital sites may be caused by immunobullous diseases such as cicatricial pemphigoid and pemphigus, and to institute appropriate investigations.
Ab initio dynamics trajectory study of the heterolytic cleavage of H2 by a Lewis acid [B(C6F5)3] and a Lewis base [P(tBu)3

Activation of H2 by a "frustrated Lewis pair" (FLP) composed of B(C6F5)3 and P(tBu)3 species has been explored with high level direct ab initio molecular dynamics (AIMD) simulations at finite temperature (T = 300 K) in gas phase. The initial geometrical conditions for the AIMD trajectory calculations, i.e., the near attack conformations of FLP + H2, were devised using the host-guest model in which suitable FLP conformations were obtained from the dynamics of the B(C6F5)3/P(tBu)3 pair in gas phase. AIMD trajectory calculations yielded microscopic insight into effects which originate from nuclear motion in the reacting complex, e.g., the alternating compression/elongation of the boron-phosphorous distance and the change of the pyramidality of boron in B(C6F5)3. The ensemble averaged trajectory analysis has been compared with the minimum energy path (MEP) description of the reaction. Similar to MEP, AIMD shows that an attack of the acid/base pair on the H-H bond gives rise to the polarization of the H2 molecule and as a consequence generates a large dipole moment of the reacting complex. The MEP and AIMD portrayals of the reaction are fundamentally different in terms of the magnitude of the motion of nuclei in B(C6F5)3 and P(tBu)3 during the H2 cleavage. In the AIMD trajectory simulations, geometries of B(C6F5)3 and P(tBu)3 appear as nearly "frozen" on the short time scale of the H2 cleavage. This is contrary to the MEP picture. Several of the concepts which arise from this work, e.g., separation of time scales of nuclear motion and the time-dependence of the donor-acceptor interactions in the reacting complex, are important for the understanding of chemical reactivity and catalysis.

Dermatological diseases, among which acne vulgaris, have psychological impact on the affected generating feelings of guilt, shame and social isolation. To compare quality of life, self-esteem and other psychosocial variables amongst adolescents with and without acne vulgaris, and between levels of severity. Cross-sectional observational study in a sample of 355 high school students from the city of João Pessoa. Data collection was performed with questionnaires and clinical-dermatological evaluation. The primary variables were the incidence of AV; quality of life, set by the Children's Dermatology Quality of Life Index and Dermatology Quality of Life Index; and self-esteem, measured by the Rosenberg Self-Esteem Scale. For calculation of statistical tests, we used the SPSS 20.0 software, considering p=0.05. The sample, with an average age of 16, showed 89.3% prevalence of acne vulgaris. The most prevalent psychosocial issue was "afraid that acne will never cease", present in 58% of affected youth. The median score of Quality of Life in Children's Dermatology Index was different amongst students with and without acne vulgaris (p=0.003), as well as the Quality of Life in Dermatology (p=0.038) scores, so that students with acne vulgaris have worse QoL. There was a correlation between the severity of acne vulgaris and worse quality of life. Self-esteem was not significantly associated with the occurrence or severity of acne vulgaris. acne vulgaris assumes significance in view of its high prevalence and the effect on quality of life of adolescents, more severe at the more pronounced stages of disease (pacne vulgaris should be valued in the management of patients with this condition.

Full Text Available ABSTRACTThe study was carried out in the University Putra Malaysia (UPM Rice Research Centre to evaluate the yield performance of newly developed selected blast resistant plants of BC2F3 generations derived from a cross between MR263, a high yielding rice variety but blast susceptible and Pongsu Seribu 1, donor with blast resistant (Pi-7(tand Pi-d (t1, Pir2-3(tgenes and qLN2 QTL, Malaysian local variety. On the basis of assessed traits, the plants 12, 6, 7, 5, 21, 22, 5, 26, 11, 8, 10, 13 and 15 had the higher yield, blast resistant and good morphological traits. More than 70% heritability was found in days to maturity, plant height, tiller numbers per hill, and panicle per hill, 80% heritability was found in filled grain and yield per hill and more than 90% heritability was found in grain length, grain width and seed weight. Cluster analysis based on the traits grouped 30 plants along with MR263 into seven clusters. According to PCA, the first four principal components account for about 69.3% total variation for all measured traits and exhibited high correlation among the characteristics analyzed.

Knowledge of black carbon (BC) emission factors from ships is important from human health and environmental perspectives. A study of instruments measuring BC and fuels typically used in marine operation was carried out on a small marine engine. Six analytical methods measured the BC emissions in the exhaust of the marine engine operated at two load points (25% and 75%) while burning one of three fuels: a distillate marine (DMA), a low sulfur, residual marine (RMB-30) and a high-sulfur residual marine (RMG-380). The average emission factors with all instruments increased from 0.08 to 1.88 gBC/kg fuel in going from 25 to 75% load. An analysis of variance (ANOVA) tested BC emissions against instrument, load, and combined fuel properties and showed that both engine load and fuels had a statistically significant impact on BC emission factors. While BC emissions were impacted by the fuels used, none of the fuel properties investigated (sulfur content, viscosity, carbon residue and CCAI) was a primary driver for BC emissions. Of the two residual fuels, RMB-30 with the lower sulfur content, lower viscosity and lower residual carbon, had the highest BC emission factors. BC emission factors determined with the different instruments showed a good correlation with the PAS values with correlation coefficients R2 >0.95. A key finding of this research is the relative BC measured values were mostly independent of load and fuel, except for some instruments in certain fuel and load combinations.
BC Citizen's Advisory Committee on oil spill prevention 1995-1996 annual report

International Nuclear Information System (INIS)

1996-01-01

A committee comprised of BC citizens with some experience in oil spill issues was established in 1990 to give advise to the BC Ministry of Environment, Lands and Parks. The committee was responsible for conducting discussions with government, industry and public representatives on the state and progress of oil spill matters, particularly on the attempts to prevent and respond to spills. Within the context of a brief report about the accomplishments of the past year, this report focused on issues raised by the BC public during three public forums. These issues were: (1) update of government activities, (2) general response capability on the BC coast and BC waters, (3) support for BC Citizen's Advisory Committee, (4) wildlife response, (5) spill prevention plans, (6) escort tugs, (7) waste oil disposal and prevention of land based sources of marine pollution, and (8) fishing and tourism concerns. The report described the discussions on the issues and summarized the recommendations for action in each of these areas of concern. 2 tabs

Acne vulgaris is a multifactorial disease. Recent study showed that inflammation does have a central role in the formation of both inflammatory and noninflammatory lesions in acne vulgaris. There are various findings of proinflammatory cytokines related to acne vulgaris, but no previous study correlate interleukin- (IL-) 19 to acne vulgaris. This pilot study aims to look at difference in IL-19 serum concentration on degrees of severity of acne vulgaris. This is an analytical observational cross-sectional study. Sample subjects were patients with acne vulgaris who met the inclusion criteria. Enzyme-linked immunosorbent assay (ELISA) study was applied to measure IL-19 serum. Analysis test found statistically significant difference between IL-19 serum concentration of group of patients with mild acne vulgaris and that of group of patients with severe acne vulgaris. Moreover, analysis revealed significant difference between IL-19 serum concentration of group of patients with moderate acne vulgaris and that of group of patients with severe acne vulgaris. There are differences in serum levels of IL-19 on the severity of acne vulgaris. The significant difference might show that inflammation has a core role in severity of acne vulgaris, and IL-19 might potentially be related to acne vulgaris.

Previous studies have demonstrated that human tissue kallikrein (TK) gene delivery protects against mouse cerebral ischemia/reperfusion (I/R) injury through bradykinin B2 receptor (B2R) activation. We have also reported that exogenous TK administration can suppress glutamate- or acidosis-induced neurotoxicity through the extracellular signal-regulated kinase1/2 (ERK1/2) pathway. To further explore the neuroprotection mechanisms of TK, in the present study we performed immunoprecipitation analysis and identified a scaffolding protein Homer1b/c using MALDI-TOF MS analysis. Here, we tested the hypothesis that TK reduces cell injury induced by oxygen and glucose deprivation/reoxygenation (OGD/R) through activating Homer1b/c. We found that TK increased the expression of Homer1b/c in a concentration- and time-dependent manner. Moreover, TK facilitated the translocation of Homer1b/c to the plasma membrane under OGD/R condition by confocal microscope assays. We also observed that overexpression of Homer1b/c showed the neuroprotection against OGD/R-induced cell injury by enhancing cell survival, reducing LDH release, caspase-3 activity and cell apoptosis. However, the knockdown of Homer1b/c by small interfering RNA showed the opposite effects, indicating that Homer1b/c had protective effects against OGD/R-induced neuronal injury. More interestingly, TK exerted its much more significantly neuroprotective effects after Homer1b/c overexpression, whereas it exerted its reduced effects after Homer1b/c knockdown. In addition, TK pretreatment increased the phosphorylation of the ERK1/2 and Akt-GSK3β through Homer1b/c activation. The beneficial effects of Homer1b/c were abolished by the ERK1/2 or PI3K antagonist. Therefore, we propose novel signaling mechanisms involved in the anti-hypoxic function of TK through activation of Homer1b/c-ERK1/2 and Homer1b/c-PI3K-Akt signaling pathways.

Full Text Available Cardiovascular disorders are the leading cause of mortality worldwide. Berberis vulgaris (B. vulgaris is a commonly used plant in traditional medicine. In recent studies, B. vulgaris showed antiarrhythmic, antihypertensive, anticholinergic, and cardioprotective effects. We reviewed the literature to explore the possible prophylactic and therapeutic roles of B. vulgaris in cardiovascular medicine. A computer literature search was conducted to identify all relevant studies that have investigated the role of B. vulgaris in prevention or treatment of cardiovascular diseases.We also searched the citations of the retrieved articles. Using a systematic approach, we conducted a scoping review that included a total of 37 articles. Twelve studies examined the antihypertensive effects of B. vulgaris, seven studies investigated its antiarrhythmic effects, while its inotropic and cardioprotective effects were evaluated in four and eight studies, respectively. B. vulgaris showed a beneficial effect in reducing blood pressure, enhancing cardiac contractility, and protection from reperfusion injury. However, the mechanisms of these effects are still under investigation. Moreover, it could modify major risk factors for cardiovascular disorders, such as oxidative stress, hyperglycemia, and hyperlipidemia. Further studies are needed to translate these findings into effective cardiovascular medications.

Background : Acne vulgaris is an inflammatory skin disorder with not as yet fully understood pathogenesis. In this controlled study, we assessed acne vulgaris patients for several possible pathogenic factors such as vitamin D deficiency, vegan diet, increased body mass index (BMI) and positive anti-transglutaminase antibody. Methods : We screened 10 years of records at a family medicine clinic for patients diagnosed with acne vulgaris. In eligible subjects, we collected data regarding 25-hydroxylvitamin D levels, BMI, dietary preference and serum IgA tissue transglutaminase levels. Controls were age- (+/- 12 months) and sex-matched patients seen during the study period without a diagnosis of acne vulgaris. Results : 453 patients were given a diagnosis of acne vulgaris during the study period. Compared with controls, we found significant associations between vitamin D deficiency (4.0U/mL) and a diagnosis of acne vulgaris. Conclusions : Our study adds important information to the current body of literature in pursuit of elucidating the pathogenesis of this complex multifactorial disease.

Triterpenoid saponins are bioactive metabolites that have evolved recurrently in plants, presumably for defense. Their biosynthesis is poorly understood, as is the relationship between bioactivity and structure. Barbarea vulgaris is the only crucifer known to produce saponins. Hederagenin and oleanolic acid cellobioside make some B. vulgaris plants resistant to important insect pests, while other, susceptible plants produce different saponins. Resistance could be caused by glucosylation of the sapogenins. We identified four family 1 glycosyltransferases (UGTs) that catalyze 3-O-glucosylation of the sapogenins oleanolic acid and hederagenin. Among these, UGT73C10 and UGT73C11 show highest activity, substrate specificity and regiospecificity, and are under positive selection, while UGT73C12 and UGT73C13 show lower substrate specificity and regiospecificity and are under purifying selection. The expression of UGT73C10 and UGT73C11 in different B. vulgaris organs correlates with saponin abundance. Monoglucosylated hederagenin and oleanolic acid were produced in vitro and tested for effects on P. nemorum. 3-O-β-d-Glc hederagenin strongly deterred feeding, while 3-O-β-d-Glc oleanolic acid only had a minor effect, showing that hydroxylation of C23 is important for resistance to this herbivore. The closest homolog in Arabidopsis thaliana, UGT73C5, only showed weak activity toward sapogenins. This indicates that UGT73C10 and UGT73C11 have neofunctionalized to specifically glucosylate sapogenins at the C3 position and demonstrates that C3 monoglucosylation activates resistance. As the UGTs from both the resistant and susceptible types of B. vulgaris glucosylate sapogenins and are not located in the known quantitative trait loci for resistance, the difference between the susceptible and resistant plant types is determined at an earlier stage in saponin biosynthesis.

Acne vulgaris is the most common skin condition affecting late adolescents across the globe. Although prior studies have evaluated epidemiologic patterns of acne vulgaris in various ethnicities and regions, adequate understanding of the worldwide burden of the disease associated with patients in their late adolescence (15-19-year olds) remains lacking. To assess the global burden of the disease associated with acne vulgaris for late adolescents (15-19-year olds) and provide an overview of the epidemiology, pathophysiology, and treatment options for acne in this population. Database summary study. Global Burden of Disease Study 2010 database. Global Burden of Disease regions comprised countries with prevalence of acne vulgaris between the ages of 15 and 19 years. Geographic region-level disability-adjusted life year rates (per 100,000 persons) associated with acne vulgaris in years 1990 through 2010. Median percentage change in disability-adjusted life year rates was estimated for each region across the specified study period. Acne vulgaris-associated disease burden exhibits global distribution and has continued to grow in prevalence over time within this population. This continued growth suggests an unmet dermatologic need worldwide for this disorder and potential opportunities for improved access and delivery of dermatologic care. Our analysis of the literature reveals numerous opportunities for enhanced patient care. To that end, we highlight some of the effective and promising treatments currently available and address important factors, such as sex, nationality, genetics, pathophysiology, and diet, as they relate to acne vulgaris in late adolescence.
Wood ethanol: a BC value-added opportunity

The environmental, economic and social benefits to be derived from the conversion of woodwaste to ethanol are reviewed as part of the justification by the Greenhouse Gas Forum, a multi-stakeholder environmental advisory group, to recommend to the BC government to support the development and commercialization of technologies to produce ethanol fuel using waste from British Columbia's sawmills. The Greenhouse Gas Forum also recommended government support for the construction of a demonstration ethanol plant by the private sector. The principal arguments underlying the Greenhouse Gas Forum's recommendations are: (1) reduction in BC's greenhouse gas emissions by one mega tonne, or two per cent of BC's 1990 emissions, (2) reducing carbon monoxide , nitrogen oxides, volatile organic compounds and other toxic emissions that contribute to urban smog, and (3) accelerating the elimination of sawmill waste burners and providing a substitute for MMT (methylcyclopentadienyl manganese tricarbonyl, a fuel additive) and MTBE ( methyl tertiary butyl ether, a component used in gasoline), thus helping to reduce health hazards from fine particulate inhalation. Economic and social benefits envisaged include creation of leading edge technology at the University of British Columbia, a substantial number of new jobs, and the potential for the development of various co-products from wood ethanol conversion. The report examines five different technologies to produce ethanol (the processes developed by Iogen, BC International, and Arkenol Inc., the Paszner ACOS process and a gasification-fermentation process), the market demand for ethanol blended gasoline and concludes that there are strong environmental, health and economic reasons for BC to increase the use of wood-ethanol as a transportation fuel and to support the establishment of an ethanol plant using wood residue. 27 refs., 5 tabs., 6 figs., 1 glossary.

The anterior mesenteric arteries of 138 horses slaughtered in southern Queensland were examined for the presence of S. vulgaris larvae. Seasonal differences were noted in the size of arterial populations of this parasite, with higher mean monthly numbers of worms per horse occurring in winter. There was an equally high incidence of severe verminous arteritis during the winter months of June, July and August, compared to arteries examined during the warmer months, when there were smaller numbers of larvae. It was concluded that more infective larvae were available on pasture during the warmer months, with subsequently large arterial populations some 3 to 4 months later. The parasite was encountered in 121 arteries (88%). The prevalence of adult helminths in the caeca of the same group of horses was S. vulgaris 88%; S. equinus 70%; S. edentatus 18%; Triodontophorus spp. 23%; A. perfoliata 62%. The overall prevalence of S. vulgaris was 93%, when the results of arterial and caecal observations were combined.

Background: Acne vulgaris is commonplace and can be difficult to manage. Providing an effective and well-tolerated treatment may lead to improved adherence, increased patient satisfaction, and improved clinical outcomes. Methods: A review of efficacy, safety, and cutaneous tolerability of clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel in 498 patients with moderate-to-severe acne vulgaris enrolled in a multicenter Phase III study randomized to receive active or vehicle once daily for 12 weeks, including the most recent post-hoc analyses. Results: Significantly superior reductions in lesion counts were observed with clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel from Week 4, with median percent reductions in inflammatory and noninflammatory lesions from baseline of 68.4 and 57.9 percent, respectively (bothpacne vulgaris patients treated with clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel achieved ≥2-grade improvement from baseline in their Evaluator’s Global Severity Score, and almost a third of the adolescent acne vulgaris patients (32.4%) achieved at least a marked improvement in their acne vulgaris as early as Week 2. In adult female acne overall treatments success was achieved in 52.7 percent of patients treated with clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel. Overall, and in the specific subpopulations, clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel was well-tolerated with a similar adverse event profile to vehicle. Limitations: Post-hoc analyses from a single clinical trial with demographic imbalances that could potentially confound the results. Conclusion: Clindamycin phosphate 1.2%-benzoyl peroxide 3.75% gel appears to be effective in treating acne across various clinically relevant sub-groups. PMID:26705445

Radiotherapy causes various complications including low immunity. Past research that the low immunity is due to the low amount of lymphocytes and consumption vulgaris will alleviate this problem. Based on this a study was conducted to identify vulgaris was able to produce radioprotection on the lymphocyte membrane. A total of 30 adult male Sprague-Dawley rats were used and divided into three equals groups of positive control and treatment. For seven days, positive control and negative control were force fed with normal saline of 40 ml/kg animal weight while the treatment group received 40g/kg animal weight fresh juice of citrullus vulgaris daily. After a week positive control an group were irradiated with 0.9 Gy gamma ray. Viable lymphocyte were determined using propidium iodine and acridine orange stain. Results clearly shows that positive con and treatment group were significantly different at 34 ± 3% , 80 ± 2% an 71 ± 2% respectively. SEM results shows that pores were present on the membrane of the pos while the negative control had none. Similar results were also found on the treatment group. Based on the result it had shown that citrullus vulgaris had radioprotection properties and lymphocytes were destroyed by the formation of pores on their membrane. It is very likely that the radioprotection properties could be due to the presence of antioxidants particularly vitamin A, C and lycopene. In conclusion, citrullus vulgaris could be used as a safe radioprotection agent. (Author)

Clindamycin 1%/benzoyl peroxide 3% fixed-dose combination gel (CLDM/BPO3%) is a topical product for the treatment of acne vulgaris. In this study, plasma and urine concentrations of benzoic acid (BA) and hippuric acid (HA) were analyzed to estimate the pharmacokinetics (PK) of BPO after application of CLDM/BPO3% twice-daily for 7 days in Japanese patients with acne vulgaris. Seven-day repeated application of CLDM/BPO3% appears to be safe in this patient population. Concentrations of plasma and urine BA were below the limit of quantification before and after repeated application in most of the 12 adult male patients. Mean difference in Cmax and AUC0-last for plasma HA indicated increased exposures after repeated application, but with wide 90% confidence intervals. Mean Ae0-12 for urine HA was similar before and after repeated application. Repeated application of CLDM/BPO3% is thus unlikely to result in accumulation of BA and HA. The study suggests negligible systemic exposure to BPO metabolites from CLDM/BPO3% after 7-day repeated application in male patients with acne vulgaris. © 2014, The American College of Clinical Pharmacology.

The biological functions of the BC047440 gene highly expressed by hepatocellular carcinoma (HCC) are unknown. The objective of this study was to reconstruct antisense eukaryotic expression vectors of the gene for inhibiting HepG 2 cell proliferation and suppressing their xenograft tumorigenicity. The full-length BC047440 cDNA was cloned from human primary HCC by RT-PCR. BC047440 gene fragments were ligated with pMD18-T simple vectors and subsequent pcDNA3.1(+) plasmids to construct the recombinant antisense eukaryotic vector pcDNA3.1(+)BC047440AS. The endogenous BC047440 mRNA abundance in target gene-transfected, vector-transfected and naive HepG 2 cells was semiquantitatively analyzed by RT-PCR and cell proliferation was measured by the MTT assay. Cell cycle distribution and apoptosis were profiled by flow cytometry. The in vivo xenograft experiment was performed on nude mice to examine the effects of antisense vector on tumorigenicity. BC047440 cDNA fragments were reversely inserted into pcDNA3.1(+) plasmids. The antisense vector significantly reduced the endogenous BC047440 mRNA abundance by 41% in HepG 2 cells and inhibited their proliferation in vitro (P < 0.01). More cells were arrested by the antisense vector at the G 1 phase in an apoptosis-independent manner (P = 0.014). Additionally, transfection with pcDNA3.1(+) BC047440AS significantly reduced the xenograft tumorigenicity in nude mice. As a novel cell cycle regulator associated with HCC, the BC047440 gene was involved in cell proliferation in vitro and xenograft tumorigenicity in vivo through apoptosis-independent mechanisms

Urban soils contain significant amounts of black carbon (BC) from biomass and fossil fuel combustion and regard to be a pool of BC. BC in urban soils has multiple effects on environmental processes in urban system, such as global climate change, air quality, and public health. Urban topsoil samples (0-10 cm) were collected from Anshan, Liaoning Province, northeast China, which is one of the most important old steel industrial bases in China. The BC in urban topsoils was extracted using the density method. Their chemical composition, morphology, molecular structure, and stable carbon isotopic composition were examined using elemental analysis, scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), X-ray diffraction (XRD), and stable carbon isotope (δ 13 C). Elemental analysis shows that carbon content in the BC of studied soils ranged from 64.5 to 78.4%, with the average more than 70%. The O/C atomic ratio of BC is on average 0.18. The BC particle displays different morphology, including porous spherical, irregular porous fragmentary, and blocky shapes. The porous spherical BC particles has atomic molar O/C ratio determined by SEM-EDS ranging from 0.04 to 0.37. XRD indicates that BC exists in mainly combining with mineral phases hematite (Fe 2 O 3 ), kaolinite (Al 2 Si 2 O 5 (OH) 4 ), quartz (SiO 2 ), and calcite (CaCO 3 ). The FTIR spectra of BC particles show major bands at approximately 3400 cm -1 (O-H), 2920 cm -1 (C = H), 1600 cm -1 (C = C), 1230 cm -1 (C = O), and 1070 cm -1 (C = O). The stable carbon isotope (δ 13 C) of BC ranges from -24.48 to -23.18‰ with the average of -23.79 ± 0.39‰. The concentration of BC in the industrial area is significantly (p fuel combustion. Results indicated that a combination of atomic O/C ratio, porous structure, and stable carbon isotopic (δ 13 C) of BC could reflect effectively the origin of BC

Acne vulgaris is the most common dermatological condition encountered in adolescents. It was to determine the prevalence of acne vulgaris and its impact of the quality of life among adolescents attending secondary schools in Sohag Province, Upper Egypt. This was a cross-sectional study conducted in randomly selected governmental and technical secondary schools in Sohag Province, Upper Egypt. Approval was taken from the scientific research committee of Sohag Faculty of Medicine and also from Ministry of Education. Every student with acne was subjected to full medical history and local examination of head and neck to assess the severity of acne vulgaris. Assessment of the impact of acne vulgaris on their quality of life was carried out using self-reported validated specific questionnaire, the Cardiff Acne Disability Index (CADI). This study included 994 teenage secondary school students. The overall prevalence of acne vulgaris was 333 (33.5%). The mean age of the students with acne was 16.84±0.87. Acne vulgaris was more common among females than among males (200, 60% vs 133, 40%). The most common form of acne vulgaris was mild 178, 53%, followed by moderate form 135, 41%, and severe form 20, 6%. CADI score was significantly related to the disease grade and it was maximum among those with severe grade, followed by moderate and lastly mild disease grade. Acne vulgaris is a common skin disease and has a valuable impact on quality of life among adolescents attending secondary schools in Sohag Province, Upper Egypt. © 2017 Wiley Periodicals, Inc.

(Chlorophyta under the influence of sodium selenite in concentrations based on Se4+ 0.5, 5.0, 10.0 and 20.0 mg/dm3 during one, three and seven days and under the influence of the simultaneous action of selenite in concentrations 10 mg Se4+/dm3 and ions of Zn2+, Mn2+, Co2+,Cu2+, Fe3+ in concentrations 5.00, 0.25, 0.05, 0.008 and 0.002 mg/dm3over seven days. This research was carried out to establish the conditions for obtaining algal lipidis substance enriched with selenium and biogenic metals in the aquaculture. The content of pigments was determined spectrophotometrically, the cellular walls were separatedby centrifuge in the percoll gradient and investigated microscopically. The pigments content in the Ch. vulgaris increased by 1.5–2.5 times in comparison with the control sample under the influence of 10 mg Se4+/dm3 with and without metal ions, in all variants of experimental influence due to binding of SeО32– with proteins and lipids. We found that selenium was included in all lipid fractions (triacylglycerols, dyacylglycerols, phospholipids, nonetherified fatty acids; the maximum amount of selenium-containing lipids wasrecorded in chloroplasts. The increase in the contents of carotenoids caused by the actions of experimental factors played an exceptional role in the mechanism of antioxidant protection that prevents destruction of chlorophyll and, accordingly, increases its amount in cells. Changes in the functioning of the photosynthetic apparatus of Ch. vulgaris affect the whole complex of metabolic transformation. Thus, the successful cultivation of chlorella, enriched with selenium and biogenic metals, is possible within seven days under the influence of 10 mg Se4+/dm3 and the above-mentioned concentration of metal ions.

Treatment of aquarium wastewater represents an important process to clean and recycle wastewater to be safely returned to the environment, used for cultivation or to minimize the multiple renewal of water. Chlorella vulgaris was an important freshwater microalgae which used in wastewater treatment, and increasing its potential of treatment can be achieved with existence of N2-fixing bacteria. Co-culturing of Chlorella vulgaris with the diazotrophs, Azospirillum brasilense or Azotobacter chroococcum in three different media; aquarium wastewater (AWW), sterile enriched natural aquarium wastewater (GPM) and synthetic wastewater media (SWW) were studied. Biomass yield of the microalgae was estimated by determination of chlorophylls (a and b), total carotenoid and the dry weight of C. vulgaris. Also determination of ammonia, nitrite, phosphate and nitrate in the culture were done. The presence of diazotrophs significantly increased the biomass of C. vulgaris by increasing its microalgae pigments (chlorophylls a and b, and total carotenoids). The highest pigments percentage was reported due to addition of A. brasilense to C. vulgaris (18.3-133.5%) compared to A. chroococcum (23.9-56.9%). As well as increased dry weight from 12 to 50%. There was also improved removal of nitrate, nitrite, ammonia and phosphate; where, the highest removal percentage was reported due to addition of A. chroococcum to C. vulgaris (0.0-52%) compared to A. brasilense (0.6-16.4%). A. brasilense and A. chroococcum can support C. vulgaris biomass production and bioremediation activity in the aquarium to minimize the periodical water renewal.

Full Text Available We consider a three receiver state dependent multilevel broadcast channel (BC, where the state information is known non-causally at the encoder as well as all the decoders. This is an extension of Nair and El Gamal’s three receiver multilevel BC (Nair and El Gamal, 2009, wherein two of the receivers decode only a common message while a third receiver decodes a private message as well. The objective is to characterize the rate tuples that are simultaneously achievable while ensuring negligible probability of error at each of the receivers. We characterize the capacity region of this setup in the paper.

Full Text Available Background: Pemphigus vulgaris is associated with high morbidity as well as significant mortality rate. Today the risk of death in pemphigus from the side effect of oral prednisolone is greater than risk of death from the disease itself. Objective: To observe the adverse effects of parenteral dexamethasone compared with oral prednisolone in the treatment of pemphigus vulgaris. Methods: An interventional study was carried out in the department of Dermatology and Venereology, Bangabandu Sheikh Mujib Medical University, Dhaka, Bangladesh. Total number of patients was thirty and among them fifteen patients were treated with parenteral dexamethasone (Group-A and other fifteen were treated with oral prednisolone (Group-B. Results: The study showed statistically significant differences of skin lesion as well as mucosal lesion of pemphigus after 6 weeks of therapy between of two groups (P<0.05. The most common adverse effects were increased body weight(40%, increased appetite(40%, and puffy face(40% in dexamethasone group. In prednisolone group, these side effects were 60% of the subjects. Other side effects in dexamethasone group were hyperglycemia (33.33%, hypertension (26.66%, and sleep disturbance (13.33%. In prednisolone group, other side effects were hyperglycemia(33.33%, hypertension(40%, gastritis (33.33%, nausea, vomiting (13.33% in each , reactivation of tuberculosis, herpes zoster infection, sleep disturbance, and mood change were 6.66% in each group. Conclusion: In the light of the findings of the study, we conclude that each of the treatment of dexamethasone group and prednisolone group is individually effective and safe in the treatment of pemphigus vulgaris but adverse effects are less in parenteral dexamethasone group than oral prednisolone group. So parenteral dexamethasone can be used as an alternative drug in the treatment of pemphigus vulgaris.
Setting the conditions for phycoremediation of radionuclide microalgae Dunaliella salina and Chlorella vulgaris

This presentation deals with bioremediation using microalgae - by phycoremediation. Microalgae are economically low profile compared to the plants, their cultivation can be carried out in laboratory conditions. They can survive in extreme conditions, they occur in all habitats and have faster growth. Halophilous green D. salina can accumulate heavy metals such as Zn, Cu and Cd. It occurs in hypersaline environment with tolerance (0.2 to 35) % NaCl. It contains high amounts of carotenoids, which protect it against formation of free radicals from UV radiation. Chlorella vulgaris is a representative of eukaryotic green microalgae with the highest chlorophyll content with the appearance in fresh water. Its phycoremediant ability are found in N and P elements, which are used as its nutritional components as well as for Cu, Cr, Cd, Pb, Au. The experiments were carried out using a peristaltic pump ISMATEC Model: ISM851 (flow rate 2 cm"3 min"-"1) followed by monitoring of time dependence of decrease of activity of the microalgae solutions. For evaluation of the samples was used HPGe gamma spectrometer (measurement time of the samples: 600 sec) from ORTEC Company and measured spectra were evaluated with software GammaVision from ORTEC. The measured results showed that the most effective phycoremediation of microalgae Dunaliella salina toke place in an environment of pH 3, and even more at pH 8. The fact that the D. salina is able of phycoremediation at so acidic pH can contribute to its applications in extreme conditions or in the coastal areas in view of that it is halophilic. At freshwater microalgae Chlorella vulgaris was found the best phytoremediation potential in its natural environment at pH of 6. Because this microalgae is freshwater, it may find application in inland or in liquid radioactive waste from nuclear facilities.(authors)

Deconstructing hydro: the BC electricity sector in this decade

International Nuclear Information System (INIS)

Jaccard, M.

2001-01-01

This paper provided speculation regarding the world-wide trend to deregulate electric utilities with particular focus on power deregulation in British Columbia. The four main issues facing electricity reform in British Columbia are to determine if publicly-owned assets should be privatised, how to achieve competitive electricity commodity prices in a de-regulated generation market, to determine the extent to which customers will be allowed direct access to sellers of electricity, and to determine which changes in industry structure are needed to ensure that control over the common carrier does not hinder fair competition. BC Hydro recently issued a plan for the next decade entitled the Integrated Electricity Plan which suggests that almost all growth in supply on the Hydro system will be limited to a few large projects totalling 900 megawatts, to be owned and operated by either BC Hydro or by the Columbia Power Corporation, another Crown entity. This plan is in complete contrast to the evolution of the electricity industry nearly everywhere else in the world where demand growth is being met almost entirely by small- and medium-scale non-utility resources issuing from competitive markets with minimal public funding. This article looks at why BC Hydro will probably be transformed significantly, even dismantled, in the coming decade. The article begins with a section explaining the cause and effects of major changes in the world-wide electricity industry. This is followed by a section reviewing what BC Hydro did in the 1990s while reform was taking place. The article also describes what BC Hydro intends to do in the next decade and explores reasons why this outcome is unlikely. The final section of the article provides an alternative vision of BC Hydro's future over the next decade. 1 tab., 3 figs

We studied the effect of genetic transformation on biologically active compound (artemisinin and its co-products (ART) as well as sugars) accumulation in Artemisia vulgaris and Artemisia dracunculus "hairy" root cultures. Glucose, fructose, sucrose, and mannitol were accumulated in A. vulgaris and A. dracunculus "hairy" root lines. Genetic transformation has led in some cases to the sugar content increasing or appearing of nonrelevant for the control plant carbohydrates. Sucrose content was 1.6 times higher in A. vulgaris "hairy" root lines. Fructose content was found to be 3.4 times higher in A. dracunculus "hairy" root cultures than in the control roots. The accumulation of mannitol was a special feature of the leaves of A. vulgaris and A. dracunculus control roots. A. vulgaris "hairy" root lines differed also in ART accumulation level. The increase of ART content up to 1.02 mg/g DW in comparison with the nontransformed roots (up to 0.687 mg/g DW) was observed. Thus, Agrobacterium rhizogenes-mediated genetic transformation can be used for obtaining of A. vulgaris and A. dracunculus "hairy" root culture produced ART and sugars in a higher amount than mother plants.

We report the first study of the $B_c^+ \\to K^+K^-\\pi^+$ decay and an update of the measurement of the ratio of branching fractions $R_{K/\\pi} \\equiv {\\cal B}(B_c^+\\to J/\\psi K^+)/{\\cal B}(B_c^+\\to J/\\psi\\pi^+)$. Both results use an integrated luminosity of $3.0fb^{-1}$ collected by the LHCb experiment in $pp$ collisions at centre-of-mass energies of 7 and 8 TeV. We measure $B_c^+ \\to \\chi_{c0}(\\to K^+ K^-)\\pi^+$ with $4.0\\sigma$ significance and $\\frac {\\sigma(B_c^+)} {\\sigma(B^+)}$ X ${\\cal B}(B_c^+ \\to \\chi_{c0}\\pi^+)$ to be $(9.8^{+3.4}_{-3.0}(stat) \\pm 0.8(syst))$ X $10^{-6}$. The contribution of $B_c^+ \\to K^+K^-\\pi^+$ via $\\overline{b}c$ weak annihilation for $m(K^-\\pi^+) < 1.834 GeV$ is measured with $2.4\\sigma$ significance. The ratio of branching fractions $R_{K/\\pi} \\equiv {\\cal B}(B_c^+ \\to J/\\psi K^+) / {\\cal B}(B_c^+ \\to J/\\psi \\pi^+)$ is measured to be $R_{K/\\pi} = 0.079 \\pm 0.007(stat) \\pm 0.003(syst)$. This result significantly improves the previous LHCb measurement.

Prunella vulgaris (Lamiaceae), commonly known as selfheal, is a perennial herb with a long history of use in traditional medicine. Recent studies have found that P. vulgaris possesses anti-inflammatory, antiviral, and antibacterial properties, and it is likely that this will lead to increased commercial demand for this species. To date, research publications on P. vulgaris cultivation and genetics are scarce. Using accessions originally collected from different geographical regions, we invest...

B.C. Hydro drops Duke Point

International Nuclear Information System (INIS)

Anon.

2005-01-01

The abandonment of the proposed natural gas-fired Duke Point Power Project on Vancouver Island was discussed. It was suggested that the continuing appeal process increases the risk that the plant will not be built in time. The news followed a decision by the British Columbia (BC) Court of Appeal to hear an appeal of the project by a number of intervenors. Over $170 million has been spent on the project to date. The decision will impact the BC treasury, as the amount is being deducted from the dividends that BC Hydro would have paid to the government. A coalition of individuals and environmental groups, as well as local industry, are opposed to the plant on the basis of increased greenhouse (GHG) emissions and higher natural gas prices. The project would have required a natural gas pipeline to be built under Georgia Strait. The project was thought necessary due to the deteriorating condition of high voltage direct current cables running under the strait. BC Hydro's fallback plan for the island is load reduction. A new transmission line is also planned

Fractional radiofrequency microneedling is a novel radiofrequency technique that uses insulated microneedles to deliver energy to the deep dermis at the point of penetration without destruction of the epidermis. It has been used for the treatment of various dermatological conditions including wrinkles, atrophic scars and hypertrophic scars. There have been few studies evaluating the efficacy of fractional radiofrequency microneedling in the treatment of acne, and none measuring objective parameters like the number of inflammatory and non-inflammatory acne lesions or sebum excretion levels. The safety and efficacy of fractional radiofrequency microneedling in the treatment of acne vulgaris was investigated. In a prospective clinical trial, 25 patients with moderate to severe acne were treated with fractional radiofrequency microneedling. The procedure was carried out three times at 1-month intervals. Acne lesion count, subjective satisfaction score, sebum excretion level and adverse effects were assessed at baseline and at 4, 8 and 12 weeks after the first treatment as well as 4, 8 and 12 weeks after the last treatment. Number of acne lesions (inflammatory and non-inflammatory) decreased. Sebum excretion and subjective satisfaction were more favorable at every time point compared with the baseline values (P acne vulgaris. © 2014 Japanese Dermatological Association.

Proliferation in vitro of peripheral blood lymphocytes both from horses infected with Strongylus vulgaris and from helminth-free ponies was observed in the presence of extracts of the fourth and fifth stage larvae and adults of S. vulgaris. In addition, S. vulgaris extracts induced transformation in cultures of peripheral blood lymphocytes from sheep and dogs and in mouse spleen cell cultures. Nylon wool non-adherent, T cell enriched fractions of lymphocytes from both mice and horses were stimulated by the S. vulgaris larval mitogen while no proliferation was observed in cultures containing nylon wool adherent, B cell enriched fractions. Macrophage co-operation appeared not to be necessary for S. vulgaris mitogen-induced transformation of spleen cells. The S. vulgaris mitogen stimulated a subpopulation of mouse spleen cells different from those responsive to PHA, Con A and LPS. These cells might be T helper cells since B cells were stimulated to proliferate in the presence of both T cells and S. vulgaris larval mitogen. In addition, the supernatant of in vitro cultured larvae of S. vulgaris induced slight, but significant transformation of equine peripheral blood lymphocytes. Therefore, it is possible that the S. vulgaris mitogen released by both viable parasites and degenerating larvae might induce T cell dependent production of immunoglobulin in vivo and account for the beta-globulinaemia, of which IgG(T) is a major component, in S vulgaris infected horses.

After 24 hours treatment, both cell lines revealed different patterns of intracellular dendrimer accumulation depending on their cytotoxic effects. Cancer cells exhibited much higher (20-fold tolerance for native PAMAM treatment than fibroblasts, whereas BC-PAMAM was significantly toxic only for fibroblasts at 50 µM concentration. Fibroblasts accumulated the native and bioconjugated dendrimers in a concentration-dependent manner at nontoxic range of concentration, with significantly lower bioconjugate loading. After reaching the cytotoxicity level, fluorescein isothiocyanate-PAMAM accumulation remains at high, comparable level. In cancer cells, native PAMAM loading at higher, but not cytotoxic concentrations, was kept at constant level with a sharp increase at toxic concentration. Mander’s coefficient calculated for fibroblasts and cancer cells confirmed more efficient native PAMAM penetration as compared to BC-PAMAM. Significant differences in nuclear dendrimer penetration were observed for both cell lines. In cancer cells, PAMAM signals amounted to ~25%–35% of the total nuclei area at all

A search for decays of $B_c^+$ mesons to two charm mesons is performed for the first time using data corresponding to an integrated luminosity of 3.0 fb$^{-1}$, collected by the LHCb experiment in $pp$ collisions at centre-of-mass energies of 7 and 8 TeV. The decays considered are $B_c^+\\to D^{(*)+}_{(s)} \\overline{D}^{(*)0}$ and $B_c^+\\to D^{(*)+}_{(s)} D^{(*)0}$, which are normalised to high-yield $B^+\\to D^+_{(s)} \\overline{D}^0$ decays. No evidence for a signal is found and limits are set on twelve $B_c^+$ decay modes

A search for the Bc meson decaying into the channels J/ψπ+ and J/ψl+vl (l = e or μ) is performed in a sample of 3.9 million hadronic Z decays collected by the ALEPH detector. This search results in the observation of 0 and 2 candidates in each of these channels, respectively, while 0.44 and 0.81 background events are expected. The following 90% confidence level upper limits are derived: Another B+c -> J/ψ(e+e-)μ+vμ candidate with very low background probability, found in an independent analysis, is also described in detail.

When antigens prepared by detergent washes of Strongylus vulgaris and Parascaris equorum were probed in an enzyme-linked immunosorbent assay test with horse sera from single species infections of S. vulgaris and P. equorum, a high degree of cross-reaction between the species was demonstrated. Western blot analysis of four common horse nematode species showed a large number of common antigens when probed with horse infection sera. Antisera raised in rabbits against the four species, including S. vulgaris, were also found to cross-react considerably. Rabbit anti-S. vulgaris sera were affinity adsorbed over a series of affinity chromatography columns, bound with cross-reactive surface antigens, to obtain S. vulgaris-specific antisera and thereby identify S. vulgaris-specific antigens by Western blotting. These studies revealed potentially specific antigens of apparent molecular weights of 100,000, 52,000, and 36,000. Of these bands, only the 52 kDa and 36 kDa appeared to be found on the surface as judged by 125I-labelling of intact worms by the Iodogen method, although neither protein was immunoprecipitated by horse infection sera. Finally, immunoprecipitation of in vitro translated proteins derived from larval S. vulgaris RNA suggests that two proteins may be parasite-derived. These findings are discussed both with respect to the surface of S. vulgaris and to the use of these species-specific antigens in immunodiagnosis.

The relationship between diet and acne is highly controversial. Several studies during the last decade have led dermatologists to reflect on a potential link between diet and acne. This article presents the latest findings on a potential impact that diet can have on pathogenesis of acne vulgaris. The association between diet and acne can no longer be dismissed. Compelling evidence shows that high glycemic load diets may exacerbate acne. Dairy ingestion appears to be weakly associated with acne and the roles of omega-3 fatty acids, dietary fiber, antioxidants, vitamin A, zinc and iodine remain to be elucidated. The question of what the impact of diet is on the course of acne vulgaris still remains unclear. PMID:27279815

This work evaluates the possibility of cultivating Scenedesmus quadricauda and Chlorella vulgaris microalgae in wastewater from the hydroponic cultivation of tomatoes with the aim of purifying the water. S. quadricauda and C. vulgaris were also used in purification tests carried out on water contaminated by the following active ingredients: metalaxyl, pyrimethanil, fenhexamid, iprodione, and triclopyr. Fifty-six days after the inoculum was placed, a reduction was found in the concentration of nitric nitrogen, ammonia nitrogen, and soluble and total phosphorus. The decrease was 99, 83, 94, and 94 %, respectively, for C. vulgaris and 99, 5, 88, and 89 %, respectively, for S. quadricauda. When the microalgae were present, all the agrochemicals tested were removed more quickly from the water than from the sterile control (BG11). The increase in the rate of degradation was in the order metalaxyl > fenhexamid > iprodione > triclopyr > pyrimethanil. It was demonstrated that there was a real degradation of fenhexamid, metalaxyl, triclopyr, and iprodione, while in the case of pyrimethanil, the active ingredient removed from the substrate was absorbed onto the cells of the microalgae. It was also found that the agrochemicals used in the tests had no significant effect on the growth of the two microalgae. The experiment highlighted the possibility of using cultivations of C. vulgaris and S. quadricauda as purification systems for agricultural wastewater which contains eutrophic inorganic compounds such as nitrates and phosphates and also different types of pesticides.

The mitochondrial respiratory chain is composed of four different protein complexes that cooperate in electron transfer and proton pumping across the inner mitochondrial membrane. The cytochrome bc1 complex, or complex III, is a component of the mitochondrial respiratory chain. This review will focus on the biogenesis of the bc1 complex in the mitochondria of the yeast Saccharomyces cerevisiae. In wild type yeast mitochondrial membranes the major part of the cytochrome bc1 complex was found in association with one or two copies of the cytochrome c oxidase complex. The analysis of several yeast mutant strains in which single genes or pairs of genes encoding bc1 subunits had been deleted revealed the presence of a common set of bc1 sub-complexes. These sub-complexes are represented by the central core of the bc1 complex, consisting of cytochrome b bound to subunit 7 and subunit 8, by the two core proteins associated with each other, by the Rieske protein associated with subunit 9, and by those deriving from the unexpected interaction of each of the two core proteins with cytochrome c1. Furthermore, a higher molecular mass sub-complex is that composed of cytochrome b, cytochrome c1, core protein 1 and 2, subunit 6, subunit 7 and subunit 8. The identification and characterization of all these sub-complexes may help in defining the steps and the molecular events leading to bc1 assembly in yeast mitochondria.

The intracellular localization and colocalization of a fluorescently labeled G3 amine-terminated cationic polyamidoamine (PAMAM) dendrimer and its biotin–pyridoxal (BC-PAMAM) bioconjugate were investigated in a concentration-dependent manner in normal human fibroblast (BJ) and squamous epithelial carcinoma (SCC-15) cell lines. After 24 hours treatment, both cell lines revealed different patterns of intracellular dendrimer accumulation depending on their cytotoxic effects. Cancer cells exhibited much higher (20-fold) tolerance for native PAMAM treatment than fibroblasts, whereas BC-PAMAM was significantly toxic only for fibroblasts at 50 µM concentration. Fibroblasts accumulated the native and bioconjugated dendrimers in a concentration-dependent manner at nontoxic range of concentration, with significantly lower bioconjugate loading. After reaching the cytotoxicity level, fluorescein isothiocyanate-PAMAM accumulation remains at high, comparable level. In cancer cells, native PAMAM loading at higher, but not cytotoxic concentrations, was kept at constant level with a sharp increase at toxic concentration. Mander’s coefficient calculated for fibroblasts and cancer cells confirmed more efficient native PAMAM penetration as compared to BC-PAMAM. Significant differences in nuclear dendrimer penetration were observed for both cell lines. In cancer cells, PAMAM signals amounted to ~25%–35% of the total nuclei area at all investigated concentrations, with lower level (15%–25%) observed for BC-PAMAM. In fibroblasts, the dendrimer nuclear signal amounted to 15% at nontoxic and up to 70% at toxic concentrations, whereas BC-PAMAM remained at a lower concentration-dependent level (0.3%–20%). Mitochondrial localization of PAMAM and BC-PAMAM revealed similar patterns in both cell lines, depending on the extracellular dendrimer concentration, and presented significantly lower signals from BC-PAMAM, which correlated well with the cytotoxicity.

Chlarella vulgaris was cultured in four different dilutions of sugar mill effluent media (SMEM). Bold's basal medium (BBM) was used as the control under laboratory conditions. Maximum cell growth and chlorophyll-a content were obtained on 10th day of the culture in 50% diluted SMEM, followed by those grown in BBM, and 75, 25 and 100% SMEM at stationary phase. The specific growth rate (mu g/day) of cells and chlorophyll-a of C. vulgaris grown in 50% SMEM varied significantly (p < 0.0 I) from those of C. vulgaris cultured in BBM, followed by other SMEM concentrations. Total biomass of C. vulgaris. cultured in 50% SMEM, was found to be significantly higher (p < 0.0 I) than that of C. vulgaris cultured in BBM, and 25, 75 and 100% SMEM concentrations. Similar trend was also observed in the case of optical density. Cell number and chlorophyll-a of C. vulgaris were highly (p < 0.01) and directly correlated with chlorophyll-a (r2 = 0.991) of C. vulgaris and optical density (r2 = 0.989) for the culture media containing C. vulgaris, respectively. Crude proteins and crude lipids of C. vulgaris. grown in 50% SMEM, were significantly (p < 0.01) higher than those of C. vulgaris cultured in other SMEM concentrations. Due to good growth performance exhibited in the 50% SMEM dilution, the sugar mill effluent may be used for efficient cultivation of C. vulgaris and possibly other micro algae. (author)

The ability of Desulfovibrio vulgaris Hildenborough to reduce, and therefore contain, toxic and radioactive metal waste has made all factors that affect the physiology of this organism of great interest. Increased salinity is an important and frequent fluctuation faced by D. vulgaris in its natural habitat. In liquid culture, exposure to excess salt resulted in striking elongation of D. vulgaris cells. Using data from transcriptomics, proteomics, metabolite assays, phospholipid fatty acid profiling, and electron microscopy, we used a systems approach to explore the effects of excess NaCl on D. vulgaris. In this study we demonstrated that import of osmoprotectants, such as glycine betaine and ectoine, is the primary mechanism used by D. vulgaris to counter hyperionic stress. Several efflux systems were also highly up-regulated, as was the ATP synthesis pathway. Increases in the levels of both RNA and DNA helicases suggested that salt stress affected the stability of nucleic acid base pairing. An overall increase in the level of branched fatty acids indicated that there were changes in cell wall fluidity. The immediate response to salt stress included up-regulation of chemotaxis genes, although flagellar biosynthesis was down-regulated. Other down-regulated systems included lactate uptake permeases and ABC transport systems. The results of an extensive NaCl stress analysis were compared with microarray data from a KCl stress analysis, and unlike many other bacteria, D. vulgaris responded similarly to the two stresses. Integration of data from multiple methods allowed us to develop a conceptual model for the salt stress response in D. vulgaris that can be compared to those in other microorganisms.
The BC-Alberta intertie : impact of regulatory change

International Nuclear Information System (INIS)

Christian, J.; Hughes, K.

2004-01-01

The interconnected electricity system between the provinces of British Columbia (BC) and Alberta was discussed with reference to the Cranbrook-Langdon 500 kV line and two 138 kV transmission lines. The lines in British Columbia are owned by BC Hydro and operated by the BC Transmission Corporation, while the lines in Alberta are owned by AltaLink and operated by the Alberta Electric Systems Operator (AESO). The operating terms and conditions are established by an Interconnection Agreement between all parties. The Alberta-BC Intertie was designed to operate at an operating transfer capacity of 1200 MW from BC to Alberta, and 1000 MW from Alberta to BC. The operational limits on Intertie capacity were imposed due to voltage constraints within Alberta during high load periods resulting from insufficient transmission support. It was noted that available capacity is often under-utilized because sometimes it is not economical to schedule into or out of Alberta due to better market conditions in the Pacific Northwest. Transmission users in BC have explicit transmission rights which must be purchased on an hourly basis. However, transmission rights in Alberta follow dispatch of generation through Power Pool bidding. The impact of an under-utilized transmission capacity is higher wholesale prices in both Alberta and in the Pacific Northwest because ratepayers end up paying for the under-used capacity. This presentation also outlined regulatory change in Alberta with reference to consolidation of Alberta's Transmission Administrator, Power Pool Administrator and system controller functions; Alberta's new transmission policy; and, the enhanced role of market surveillance administrator. It also outlined the regulatory change in British Columbia with reference to the creation of the BC Transmission Corporation; the Heritage Contract; and, stepped rates and retail access. The effect of changes on intertie usage in both Alberta and British Columbia were also outlined. 31 refs

Ab initio pseudopotential total-energy and phonon calculations have been carried out to examine the changes in the structural parameters, bonding behaviours, band structures, and dynamic instabilities caused by phonon softening in these phases. We find that an experimentally synthesized high-density phase of cubic BC 2 N exhibits outstanding stability in the structural and electronic properties up to very high pressures. On the other hand, another experimentally identified phase with lower density and lower symmetry undergoes a dramatic structural transformation with a volume and bond-length collapse and a concomitant semi-metal to semiconductor transition. A third phase is predicted to be favourable over the above-mentioned lower-density phase by the enthalpy calculations. However, the dynamic phonon calculations reveal that it develops imaginary phonon modes and, therefore, is unstable in the experimental pressure range. The calculations indicate that its synthesis may be achieved at reduced pressures. These results provide a comprehensive understanding for the high-pressure behaviour of the cubic BC 2 N phases and reveal their interesting properties that can be verified by experiments

Full Text Available Von Hippel-Lindau tumor suppressor protein (pVHL functions to induce neuronal differentiation of neural stem/progenitor cells (NSCs and skin-derived precursors (SKPs. Here we identified a neuronal differentiation domain (NDD in pVHL. Neuronal differentiation of SKPs was induced by intracellular delivery of a peptide composed of the amino-acid sequences encoded by the NDD. Neuronal differentiation mediated by the NDD was caused by the binding between it and elongin C followed by Janus kinase-2 (JAK2 ubiquitination of JAK2 and inhibition of the JAK2/the signal transducer and activator of transcription-3(STAT3 pathway. The NDD in pVHL contained the BC-box motif ((A,P,S,TLXXX (A,C XXX(A,I,L,V corresponding to the binding site of elongin C. Therefore, we proposed that other BC-box proteins might also contain an NDD; and subsequently also identified in them an NDD containing the amino-acid sequence encoded by the BC-box motif in BC-box proteins. Furthermore, we showed that different NDD peptide-delivered cells differentiated into different kinds of neuron-like cells. That is, dopaminergic neuron-like cells, cholinergic neuron-like cells, GABAnergic neuron-like cells or rhodopsin-positive neuron-like cells were induced by different NDD peptides. These novel findings might contribute to the development of a new method for promoting neuronal differentiation and shed further light on the mechanism of neuronal differentiation of somatic stem cells.

Full Text Available Abstract The symmetry properties of the single-walled BC2N nanotubes were investigated. All the BC2N nanotubes possess nonsymmorphic line groups. In contrast with the carbon and boron nitride nanotubes, armchair and zigzag BC2N nanotubes belong to different line groups, depending on the index n (even or odd and the vector chosen. The number of Raman- active phonon modes is almost twice that of the infrared-active phonon modes for all kinds of BC2N nanotubes.

Between August 1978 and July 1979 the anterior mesenteric artery and its branches were collected regularly from adult horses and examined for Strongylus vulgaris larvae. The incidence of infection varied from 55 to 100% (annual mean 80%). The mean monthly number of larvae ranged form 3 to 22 with an annual overall mean of 13. The arterial infection was at its minimum in December to January, rose gradually to attain the peak in June and declined thereafter. These observations indicated that S. vulgaris is an annual species in Morocco, infection occurring during the rainy season (November-April), the heavy arterial population in spring and adult population during autumn and winter.

The epidemiology and control of helminth infections in the horse were studied in four small grazing experiments between 1981 and 1984 at the University of Utrecht. At autopsy in November or December negligible Strongylus vulgaris burdens were found in the cranial mesenteric artery of four groups of ponies, which had been treated with an anthelmintic in July and subsequently transferred to a clean pasture. Considerable arterial S. vulgaris burdens were seen in three groups of ponies which were treated with an anthelmintic in July without a move to clean pasture, and in another group of ponies in 1984, which was set stocked on a pasture used for horses in 1983 and which was treated with an anthelmintic (albendazole) 2 days before turnout in April and subsequently in May, June and July. A tracer pony, grazed with this group between the middle of September and the middle of November, harboured an even higher burden of arterial S. vulgaris larvae. The arterial S. vulgaris in the latter group could not be the result of contamination of the pasture with S. vulgaris eggs before July, as in the three other groups with considerable arterial S. vulgaris burdens. Pasture larval counts showed that S. vulgaris larvae do not only overwinter, but are able to survive in considerable numbers until autumn, longer than most other gastrointestinal nematodes. There were some indications that translation of infective larvae, which overwintered on pasture in some free living stage, occurred between May and July.

More than 99% acne patients suffer from acne vulgaris. While diagnosing the severity of acne vulgaris lesions, dermatologists have observed inter-rater and intra-rater variability in diagnosis results. This is because during assessment, identifying lesion types and their counting is a tedious job for dermatologists. To make the assessment job objective and easier for dermatologists, an automated system based on image processing methods is proposed in this study. There are two main objectives: (i) to develop an algorithm for the enhancement of various acne vulgaris lesions; and (ii) to develop a method for the segmentation of enhanced acne vulgaris lesions. For the first objective, an algorithm is developed based on the theory of high dynamic range (HDR) images. The proposed algorithm uses local rank transform to generate the HDR images from a single acne image followed by the log transformation. Then, segmentation is performed by clustering the pixels based on Mahalanobis distance of each pixel from spectral models of acne vulgaris lesions. Two metrics are used to evaluate the enhancement of acne vulgaris lesions, i.e., contrast improvement factor (CIF) and image contrast normalization (ICN). The proposed algorithm is compared with two other methods. The proposed enhancement algorithm shows better result than both the other methods based on CIF and ICN. In addition, sensitivity and specificity are calculated for the segmentation results. The proposed segmentation method shows higher sensitivity and specificity than other methods. This article specifically discusses the contrast enhancement and segmentation for automated diagnosis system of acne vulgaris lesions. The results are promising that can be used for further classification of acne vulgaris lesions for final grading of the lesions. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The effects of the polycyclic aromatic hydrocarbon phenanthrene on the growth of chlorella vulgaris alga were evaluated under laboratory conditions. The algae were exposed during 72 h to different concentrations of phenanthrene (0, 1, 10, 100, 1000 and 10000 μg/l). The alga density was daily determined by a neubauer chamber. The average growth average, total biomass and inhibition percentage of the biomass were also determined. In addition, the content of chlorophyll a was determined at the beginning and the end of the experiment. the assays were carried out in glass bottles of 0,4 l using the complex NPK (remital m 17-6-18) at 1 g/l as an organic fertilizing. The results showed that phenanthrene inhibited progressively the alga growth being the lowest cellular growth observed in the medium with the highest phenanthrene concentration, reaching an inhibition percentage of 59 %. In the other treatments, the daily growth rate was relatively constant. The chlorophyll a concentration evaluated by spectrophotometry was not affected by the phenanthrene concentration. in conclusion, the growth of the alga c. vulgaris was affected negatively by the exposure to nominal concentrations of the polycyclic aromatic hydrocarbon phenanthrene higher than 1 μg/l.

Strongyle parasites are ubiquitous in grazing horses. Of these, the bloodworm Strongylus vulgaris is regarded as most pathogenic. Increasing levels of anthelmintic resistance in strongyle parasites has led to recommendations of decreased treatment intensities, and there is now a pronounced need for reliable tools for detection of parasite burdens in general and S. vulgaris in particular. The only method currently available for diagnosing S. vulgaris in practice is the larval culture, which is laborious and time-consuming, so veterinary practitioners most often pool samples from several horses together in one culture to save time. Recently, molecular tools have been developed to detect S. vulgaris in faecal samples. The aim of this study was to compare the performance of a conventional polymerase chain reaction (PCR) assay with the traditional larval culture and furthermore test the performance of pooled versus individual PCR for farm screening purposes. Faecal samples were obtained from 331 horses on 18 different farms. Farm size ranged from 6 to 56 horses, and horses aged between 2 months and 31 years. Larval cultures and PCR were performed individually on all horses. In addition, PCR was performed on 66 faecal pools consisting of 3-5 horses each. Species-specific PCR primers previously developed were used for the PCR. PCR and larval culture detected S. vulgaris in 12.1 and 4.5% of individual horses, respectively. On the farm level, eight farms tested positive with the larval culture, while 13 and 11 farms were positive with the individual and pooled PCRs, respectively. The individual PCR method was statistically superior to the larval culture, while no statistical difference could be detected between pooled and individual PCR for farm screening. In conclusion, pooled PCR appears to be a useful tool for farm screening for S. vulgaris. Copyright © 2011 Elsevier B.V. All rights reserved.

Full Text Available Background. Autoimmune process and immunosuppressive therapy of pemphigus vulgaris would predispose the patients to infections. Aim. We aimed to study the prevalence of infection and pathogenic agents in pemphigus vulgaris patients admitted to dermatology service. Material and methods. This retrospective study was conducted on 155 pemphigus vulgaris patients (68 males, 87 females admitted to dermatology service between 2009 and 2011. In this study, the diagnosis of pemphigus vulgaris was confirmed by light microscopic and direct immunofluorescence findings. Data were collected through a questionnaire. Results. Of 155 pemphigus vulgaris patients, 33 had infection at admission and 9 acquired nosocomial infection. In addition, 37 cases of oral candidiasis and 15 cases of localized herpes simplex were recorded. Totally, 94 cases of infection were recorded. The occurrence of infection was significantly related to the severity of disease, number of hospital admissions, and presence of diabetes mellitus. The most common pathogenic germs isolated from cultures were Staphylococcus aureus and Escherichia coli. Conclusion. Severity of pemphigus vulgaris and diabetes were directly related with tendency to infections. Staphylococcus aureus and Escherichia coli were the most common pathogenic agents. Due to limitations of retrospective study, a prospective study is recommended.

A comparative study of n-γ discrimination by the digital charge comparison method was carried out for NE213 and BC501A scintillators of different size coupled to a 130 mm diameter XP4512B photomultiplier. Particularly, the scintillators of diameter 50 mmx50 mm size are compared with those of 4 l volume (160 mm in diameter and 200 mm in depth). The figure of merit, M, of 3.81 measured with the diameter 50 mmx50 mm BC501A scintillator at 1 MeV energy lost by recoil electrons, is much better than M of 2.05 as observed with the 4 l volume cell. This is the effect of the reduced photoelectron yield by about 50% determined for the 4 l volume scintillator. Moreover, the slowing down of the light pulse and multiscattering of neutrons have a further influence on the lowering of the M factor. The study of the M factor versus the initial delay and width of the gate set at the slow component showed that the early light of the slow component represented often by the intermediate component with the decay time constant of about 30 ns is of great importance for the n-γ discrimination. Particularly, for the 4 l volume cells it is sufficient to limit the width of the gate at the slow component to about 300 ns. The comparison of the NE213 and BC501A scintillators showed that the BC501A scintillator exhibits a larger light yield evidently observed for the 4 l volume cell and thus giving a better n-γ discrimination.

Food waste contains large amount of organic matter that may be troublesome for handing, storage and transportation. A microbial fuel cell (MFC) was successfully constructed with different inoculum densities of Chlorella vulgaris for promoting food waste treatment. Maximum COD removal efficiency was registered with 44% and 25 g CODL(-1)d(-1) of substrate degradation rate when inoculated with the optimal initial density (150 mg L(-1)) of C. vulgaris, which were 2.9 times and 3.1 times higher than that of the abiotic cathode. With the optimum inoculum density of C. vulgaris, the highest open circuit voltage, working voltage and power density of MFC were 260 mV, 170 mV and 19151 mW m(-3), respectively. Besides the high biodiesel quality, promoted by MFC stimulation the biomass productivity and highest total lipid content of C. vulgaris were 207 mg L(-1)d(-1) and 31%, which were roughly 2.7 times and 1.2 times higher than the control group.

Nematodes belonging to the order Strongylida are ubiquitous in grazing horses, and the large strongyle Strongylus vulgaris is considered the most pathogenic. This parasite was originally described widely prevalent in equine establishments, but decades of frequent anthelmintic treatment appears to have reduced the prevalence dramatically. Increasing levels of anthelmintic resistance in cyathostomin parasites have led to implementation of selective therapy to reduce further development of resistance. It has been hypothesized that S. vulgaris could reoccur under these less intensive treatment circumstances. The aim with the present study was to evaluate the occurrence of S. vulgaris and the possible association with usage of selective therapy. A total of 42 horse farms in Denmark were evaluated for the presence of S. vulgaris using individual larval cultures. Farms were either using a selective therapy principle based on regular fecal egg counts from all horses, or they treated strategically without using fecal egg counts. A total of 662 horses were included in the study. Covariate information at the farm and horse level was collected using a questionnaire. The overall prevalence of S. vulgaris was 12.2% at the individual level and 64.3% at the farm level. Farms using selective therapy had horse and farm prevalences of 15.4% and 83.3%, respectively, while the corresponding results for farms not using selective therapy were 7.7% and 38.9%. These findings were found statistically significant at both the horse and the farm level. Stud farms using selective therapy were especially at risk, and occurrence of S. vulgaris was significantly associated with the most recent deworming occurring more than six months prior. The results suggest that a strict interpretation of the selective therapy regimen can be associated with an increased prevalence of S. vulgaris. This suggests that modifications of the parasite control programs could be considered on the studied farms, but it

Evidence that assembly of the yeast cytochrome bc1 complex involves formation of a large core structure in the inner mitochondrial membrane

Zara, Vincenzo; Conte, Laura; Trumpower, Bernard L.

2009-01-01

The assembly status of the cytochrome bc1 complex has been analyzed in distinct yeast deletion strains in which genes for one or more of the bc1 subunits had been deleted. In all the yeast strains tested a bc1 sub-complex of about 500 kDa was found when the mitochondrial membranes were analyzed by blue native electrophoresis. The subsequent molecular characterization of this sub-complex, carried out in the second dimension by SDS-PAGE and immunodecoration, revealed the presence of the two catalytic subunits cytochrome b and cytochrome c1, associated with the non catalytic subunits core protein 1, core protein 2, Qcr7p and Qcr8p. Altogether these bc1 subunits build up the core structure of the cytochrome bc1 complex which is then able to sequentially bind the remaining subunits, such as Qcr6p, Qcr9p, the Rieske iron-sulfur protein and Qcr10p. This bc1 core structure may represent a true assembly intermediate during the maturation of the bc1 complex, first because of its wide distribution in distinct yeast deletion strains and second for its characteristics of stability which resemble those of the intact homodimeric bc1 complex. Differently from this latter, however, the bc1 core structure is not able to interact with the cytochrome c oxidase complex to form respiratory supercomplexes. The characterization of this novel core structure of the bc1 complex provides a number of new elements for clarification of the molecular events leading to the maturation of the yeast cytochrome bc1 complex in the inner mitochondrial membrane.

There were several common antigens. Excretory and secretory products were collected als...
Identification of BC005512 as a DNA damage responsive murine endogenous retrovirus of GLN family involved in cell growth regulation.

Full Text Available Genotoxicity assessment is of great significance in drug safety evaluation, and microarray is a useful tool widely used to identify genotoxic stress responsive genes. In the present work, by using oligonucleotide microarray in an in vivo model, we identified an unknown gene BC005512 (abbreviated as BC, official full name: cDNA sequence BC005512, whose expression in mouse liver was specifically induced by seven well-known genotoxins (GTXs, but not by non-genotoxins (NGTXs. Bioinformatics revealed that BC was a member of the GLN family of murine endogenous retrovirus (ERV. However, the relationship to genotoxicity and the cellular function of GLN are largely unknown. Using NIH/3T3 cells as an in vitro model system and quantitative real-time PCR, BC expression was specifically induced by another seven GTXs, covering diverse genotoxicity mechanisms. Additionally, dose-response and linear regression analysis showed that expression level of BC in NIH/3T3 cells strongly correlated with DNA damage, measured using the alkaline comet assay,. While in p53 deficient L5178Y cells, GTXs could not induce BC expression. Further functional studies using RNA interference revealed that down-regulation of BC expression induced G1/S phase arrest, inhibited cell proliferation and thus suppressed cell growth in NIH/3T3 cells. Together, our results provide the first evidence that BC005512, a member from GLN family of murine ERV, was responsive to DNA damage and involved in cell growth regulation. These findings could be of great value in genotoxicity predictions and contribute to a deeper understanding of GLN biological functions.

Full Text Available Jonette Keri1,2, Michael Shiman11Department of Dermatology and Cutaneous Surgery, University of Miami Miller School of Medicine, Miami, FL, USA; 2Dermatology Service, Miami VA Hospital, FL, USAAbstract: Acne vulgaris is a common skin disorder that can affect individuals from childhood to adulthood, most often occurring in the teenage years. Acne can have a significant physical, emotional, and social impact on an individual. Many different treatment options are available for the treatment of acne vulgaris. Commonly used topical treatments include benzoyl peroxide, antibiotics, sulfur and sodium sulfacetamide, azelaic acid, and retinoids. Systemic treatment is frequently used and includes the use of systemic antibiotics, oral contraceptives, antiandrogens, and retinoids. Other treatment modalities exist such as the use of superficial chemical peels as well as using laser and light devices for the treatment of acne. With the multitude of treatment options and the rapidly expanding newer technologies available to clinicians, it is important to review and be aware of the current literature and studies regarding the treatment of acne vulgaris.Keywords: acne vulgaris, treatment, benzoyl peroxide, antibiotics, retinoids, lasers

Eight of 10 pony foals reared under helminth-free conditions were inoculated PO with 50 Strongylus vulgaris infective larvae/week for 4 weeks, at which time 1 foal died of acute verminous arteritis. Inoculation of 7 remaining foals continued at 2-week intervals for 20 weeks. Of the 7 foals, 3 were treated with ivermectin (0.2 mg/kg of body weight) in an oral paste formulation at experiment weeks 8, 16, 24; 4 foals were not treated. Two foals were not inoculated or treated and served as controls. After the first ivermectin treatment, ivermectin-treated foals had fewer days (12 +/- 2.9) with rectal temperatures greater than 38.6 C than did nontreated foals (23.3 +/- 3.8). Mean baseline rectal temperatures were 38 +/- 0.2 C. Adverse clinical reactions to ivermectin treatment were not observed in foals. Foals were euthanatized and necropsied 3 weeks after the last ivermectin treatment (week 24). Ivermectin was effective in reducing S vulgaris arterial larval and intestinal adult parasite numbers by 100% in 3 treated foals. Strongylus vulgaris arterial larvae and/or adults were recovered from all 4 nontreated inoculated foals. One nontreated inoculated foal lacked arterial larvae or active arterial lesions, indicating that protective resistance had developed in this individual. Marked gross and histopathologic lesions typical of chronic S vulgaris infection were observed in the 3 nontreated inoculated foals with arterial larvae. Repeated killing of intra-arterial S vulgaris fourth-stage larvae in ivermectin-treated foals did not exacerbate lesions associated with verminous arteritis or induce unique lesions associated with repeated destruction of arterial larvae.(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of this study was to determine the in vitro anti-inflammatory activities of solvent fractions from Chlorella vulgaris by inhibiting the production of pro-inflammatory mediators and cytokines. Methanolic extracts (80%) of C. vulgaris were prepared and partitioned with solvents of increasing polarity viz., n-hexane, chloroform, ethanol, and water. Various concentrations of the fractions were tested for cytotoxicity in RAW 264.7 cells using 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, and the concentrations inducing cell growth inhibition by about 50% (IC50) were chosen for further studies. Lipopolysaccharide (LPS) stimulated RAW 264.7 cells were treated with varying concentrations of C. vulgaris fractions and examined for its effects on nitric oxide (NO) production by Griess assay. The release of prostaglandin E2 (PGE2), tumor necrosis factor-α (TNF-α), and interleukin 6 (IL-6) were quantified using enzyme-linked immunosorbent assay using Celecoxib and polymyxin B as positive controls. MTT assay revealed all the solvent fractions that inhibited cell growth in a dose-dependent manner. Of all the extracts, 80% methanolic extract exhibited the strongest anti-inflammatory activity by inhibiting NO production (P < 0.01), PGE2 (P < 0.05), TNF-α, and IL-6 (P < 0.001) release in LPS induced RAW 264.7 cells. Both hexane and chloroform fractions recorded a significant (P < 0.05) and dose-dependent inhibition of LPS induced inflammatory mediators and cytokines in vitro. The anti-inflammatory effect of ethanol and aqueous extracts was not significant in the study. The significant inhibition of inflammatory mediators and cytokines by fractions from C. vulgaris suggests that this microalga would be a potential source of developing anti-inflammatory agents and a good alternate for conventional steroidal and nonsteroidal anti-inflammatory drugs. C. vulgaris extracts have potential anti-inflammatory activitySolvent extraction using methanol

2014-07-01

Acne may present in neonates, infants, and small children. Neonatal and infantile acne vulgaris are not considered to be rare. The presentation of acne in this patient population sometimes represents virilization and may portend later development of severe adolescent acne. Neonatal and infantile acne vulgaris must be distinguished from other cutaneous disorders seen in newborns and infants. Infantile acne tends to be more pleomorphic and inflammatory, thus requiring more vigorous therapy than neonatal acne.
Climate impact on BC Hydro's water resources

BC Hydro like many other hydro utilities has used the historical record of weather and runoff as the standard description the variability and uncertainty of the key weather drivers for its operation and planning studies. It has been conveniently assumed that this historical record is or has been statistically stationary and therefore is assumed to represent the future characteristics of climatic drivers on our system. This assumption is obviously no longer justifiable. To address the characterisation of future weather, BC Hydro has a multi-year a directed research program with the Pacific Climate Impacts Consortium to evaluate the impacts of climate change on the water resources that BC Hydro manages for hydropower generation and other uses. The objective of this program is to derive climate change adjusted meteorologic and hydrologic sequences suitable for use in system operations and planning studies. These climate-adjusted sequences then can be used to test system sensitivity to climate change scenarios relative to the baseline of the historical record. This paper describes BC Hydro's research program and the results achieved so far. (author)

Activity of ivermectin, administered IM at the dosage rate of 200 micrograms/kg of body weight, was evaluated in controlled tests against migrating larvae of Strongylus vulgaris and adult Trichostrongylus axei in experimental infections in 6 ponies raised worm-free. Ponies were given 2,190 or 2,400 infective 3rd-stage larvae of S vulgaris at 7 days before treatment and 22,000 or 22,750 infective 3rd-stage larvae of T axei at 42 or 45 days before treatment. Three ponies were given ivermectin plus vehicle, and 3 ponies were given the vehicle only; the ponies were euthanatized 7 or 9 days after treatment. At necropsy, 4th-stage S vulgaris larvae were not recovered from visceral arteries of the 3 ivermectin plus vehicle-treated ponies, but 21 to 40 larvae were recovered from each of the 3 vehicle-treated ponies. Also at necropsy, adult T axei (140 specimens) were recovered from only 1 ot the 3 ivermectin plus vehicle-treated ponies, but 4,610 to 6,410 specimens were found in each of the 3 vehicle-treated ponies. Toxicosis was not observed after treatment.

DYNAMICAL MASS OF THE SUBSTELLAR BENCHMARK BINARY HD 130948BC , ,

Dupuy, Trent J.; Liu, Michael C.; Ireland, Michael J.

2009-01-01

We present Keck adaptive optics imaging of the L4+L4 binary HD 130948BC along with archival Hubble Space Telescope and Gemini North observations, which together span ∼ 70% of the binary's orbital period. From the relative orbit, we determine a total dynamical mass of 0.109 ± 0.003 M sun (114 ± 3 M Jup ). The flux ratio of HD 130948BC is near unity, so both components are unambiguously substellar for any plausible mass ratio. An independent constraint on the age of the system is available from the primary HD 130948A (G2V, [M/H] = 0.0). The ensemble of available indicators suggests an age comparable to Hyades, with the most precise age being 0.79 +0.22 -0.15 Gyr based on gyrochronology. Therefore, HD 130948BC is now a unique benchmark among field L and T dwarfs, with a well-determined mass, luminosity, and age. We find that substellar theoretical models disagree with our observations. (1) Both components of HD 130948BC appear to be overluminous by a factor of ∼ 2-3 times compared to evolutionary models. The age of the system would have to be notably younger than the gyro age to ameliorate the luminosity disagreement. (2) Effective temperatures derived from evolutionary models for HD 130948B and C are inconsistent with temperatures determined from spectral synthesis for objects of similar spectral type. Overall, regardless of the adopted age, evolutionary and atmospheric models give inconsistent results, which indicate systematic errors in at least one class of models, possibly both. The masses of HD 130948BC happen to be very near the theoretical mass limit for lithium burning, and thus measuring the differential lithium depletion between B and C will provide a uniquely discriminating test of theoretical models. The potential underestimate of luminosities by evolutionary models would have wide-ranging implications; therefore, a more refined estimate age for HD 130948A is critically needed.

To investigate the efficacy and safety of low-concentration 5-aminolevulinic acid photodynamic therapy (ALA-PDT) in the treatment of different severity of acne vulgaris and optimize the treatment regimen. A self-controlled multicenter clinical trial was carried out in 15 centers throughout China. A total of 397 acne patients of grade II-IV received 3- or 4-session PDT treatment. 5% ALA gel was applied topically to acne lesions for 1h incubation. The lesions were irradiated by a LED light of 633 nm at dose levels of 96-120 J/cm(2). Clinical assessment was conducted before and after every treatment up to 8 weeks. The effective rate overall and of grade II, III and IV are 82.1%, 71.6%, 79.6% and 88.2%, respectively. The effective rate rises significantly proportionally to the severity of acne (P0.05). The count of inflammatory and non-inflammatory acne lesions gradually decrease after each treatment (Pacne vulgaris in Chinese patients. Superior efficacy is found in severe cystic acne of grade IV with mild side effects. Copyright © 2013 Elsevier B.V. All rights reserved.

Full Text Available Chlorella vulgaris has the gene of n-3 fatty acid desaturase (CvFad3, which can synthesize the precursor of n-3 polyunsaturated fatty acids (PUFAs or convert n-6 to n-3 PUFAs. The objective of the present study was to examine whether the CvFad3 gene from C. vulgaris can be functionally and efficiently expressed in human breast cancer cells and whether its expression can exert a significant effect on cell fatty acid composition. We inserted the CvFad3 gene into the plasmid pEGFP-C3 to construct the eukaryotic expression vector pEGFP-C3-n-3 and to express the n-3 Fad gene in human breast cancer cells (MCF-7 cells. Transfection of MCF-7 cells with the recombinant vector resulted in a high expression of n-3 fatty acid desaturase. Lipid analysis indicated that the ratio of n-6/n-3 PUFAs was decreased from 6:1 in the control cells to about 1:1 in the cells expressing the n-3 fatty acid desaturase. Accordingly, the CvFad3 gene significantly decreased the ratio of n-6/n-3 PUFAs of the MCF-7 cell membrane. The expression of the CvFad3 gene can decrease cell proliferation and promote cell apoptosis. This study demonstrates that the CvFad3 gene can dramatically balance the ratio of n-6/n-3 PUFAs and may provide an effective approach to the modification of the fatty acid composition of mammalian cells, also providing a basis for potential applications of its transfer in experimental and clinical settings.

The morphology and adhesion mechanism of Octopus vulgaris suckers.

Directory of Open Access Journals (Sweden)

Francesca Tramacere

Full Text Available The octopus sucker represents a fascinating natural system performing adhesion on different terrains and substrates. Octopuses use suckers to anchor the body to the substrate or to grasp, investigate and manipulate objects, just to mention a few of their functions. Our study focuses on the morphology and adhesion mechanism of suckers in Octopus vulgaris. We use three different techniques (MRI, ultrasonography, and histology and a 3D reconstruction approach to contribute knowledge on both morphology and functionality of the sucker structure in O. vulgaris. The results of our investigation are two-fold. First, we observe some morphological differences with respect to the octopus species previously studied (i.e., Octopus joubini, Octopus maya, Octopus bimaculoides/bimaculatus and Eledone cirrosa. In particular, in O. vulgaris the acetabular chamber, that is a hollow spherical cavity in other octopuses, shows an ellipsoidal cavity which roof has an important protuberance with surface roughness. Second, based on our findings, we propose a hypothesis on the sucker adhesion mechanism in O. vulgaris. We hypothesize that the process of continuous adhesion is achieved by sealing the orifice between acetabulum and infundibulum portions via the acetabular protuberance. We suggest this to take place while the infundibular part achieves a completely flat shape; and, by sustaining adhesion through preservation of sucker configuration. In vivo ultrasonographic recordings support our proposed adhesion model by showing the sucker in action. Such an underlying physical mechanism offers innovative potential cues for developing bioinspired artificial adhesion systems. Furthermore, we think that it could possibly represent a useful approach in order to investigate any potential difference in the ecology and in the performance of adhesion by different species.

The octopus sucker represents a fascinating natural system performing adhesion on different terrains and substrates. Octopuses use suckers to anchor the body to the substrate or to grasp, investigate and manipulate objects, just to mention a few of their functions. Our study focuses on the morphology and adhesion mechanism of suckers in Octopus vulgaris. We use three different techniques (MRI, ultrasonography, and histology) and a 3D reconstruction approach to contribute knowledge on both morphology and functionality of the sucker structure in O. vulgaris. The results of our investigation are two-fold. First, we observe some morphological differences with respect to the octopus species previously studied (i.e., Octopus joubini, Octopus maya, Octopus bimaculoides/bimaculatus and Eledone cirrosa). In particular, in O. vulgaris the acetabular chamber, that is a hollow spherical cavity in other octopuses, shows an ellipsoidal cavity which roof has an important protuberance with surface roughness. Second, based on our findings, we propose a hypothesis on the sucker adhesion mechanism in O. vulgaris. We hypothesize that the process of continuous adhesion is achieved by sealing the orifice between acetabulum and infundibulum portions via the acetabular protuberance. We suggest this to take place while the infundibular part achieves a completely flat shape; and, by sustaining adhesion through preservation of sucker configuration.

CO2 biofixation was investigated using tubular bioreactors (15 and 1.5 l) either in the presence of green algae Chlorella vulgaris or Nannochloropsis gaditana. The cultivation was carried out in the following conditions: temperature of 25 °C, inlet-CO2 of 4 and 8 vol%, and artificial light enhancing photosynthesis. Higher biofixation were observed in 8 vol% CO2 concentration for both microalgae cultures than in 4 vol%. Characteristic process parameters such as productivity, CO2 fixation, and kinetic rate coefficient were determined and discussed. Simplified and advanced methods for determination of CO2 fixation were compared. In a simplified method, it is assumed that 1 kg of produced biomass equals 1.88 kg recycled CO2. Advance method is based on empirical results of the present study (formula with carbon content in biomass). It was observed that application of the simplified method can generate large errors, especially if the biomass contains a relatively low amount of carbon. N. gaditana is the recommended species for CO2 removal due to a high biofixation rate-more than 1.7 g/l/day. On day 10 of cultivation, the cell concentration was more than 1.7 × 10(7) cells/ml. In the case of C. vulgaris, the maximal biofixation rate and cell concentration did not exceed 1.4 g/l/day and 1.3 × 10(7) cells/ml, respectively.

A search for decays of the B_c meson was performed using data collected from 1990-1995 with the OPAL detector on or near the Z peak at LEP. The decay channels B_c^+ -> J/psi pi^+, B_c^+ -> J/psi a_1^+ and B_c^+ -> J/psi ell^+ nu were investigated, where ell denotes an electron or a muon. Two candidates are observed in the mode B_c^+ -> J/psi pi^+, with an estimated background of (0.63 +/- 0.20) events. The weighted mean of the masses of the two candidates is (6.32 +/- 0.06) GeV/c^2, which is consistent with the predicted mass of the B_c meson. One candidate event is observed in the mode B_c^+ -> J/psi ell^+ nu with an estimated background of (0.82 +/- 0.19) events. No candidate events are observed in the B_c^+ -> J/psi a_1^+ decay mode, with an estimated background of (1.10 +/- 0.22) events. Upper bounds at the 90% confidence level are set on the production rates for these processes.

Economic impacts of the BC recycling regulation

Extended producer responsibility (EPR) is an environmental approach used in British Columbia (BC) to consider the entire life cycle of a product from the selection and materials and design to the post-consumer stage. This paper discussed EPR strategies that are currently being used to help the BC government remove toxins from its waste stream and develop recycling programs that contribute to the sustainable use of BC's resources. BC's recycling regulation was designed to ensure that producers of designated materials take responsibility for managing products at end-of-life under approved product stewardship plans. The stewardship management recycling program has provided an estimated 1600 full-time equivalent jobs in the province. Overall employment rates are expected to reach over 2100. A waste reduction model (WARM) analysis showed that BC stewardships provide an estimated reduction of 73,000 metric tonnes of carbon equivalent (MTCE). Aluminum can and tire recycling programs account for 82 per cent of the reductions. Diverting the wastes from landfill has helped to avoid the costs of remedial clean-ups as well as avoid the costs of handling hazardous materials. It was concluded that total revenues of $109 million were earned in 2007 from fees, deposits, and the sale of recovered materials. Separate data were provided for stewardship programs for beverage containers; beer containers; tires; used oil; electronics; paint, flammables, and pesticides; tree paint; and pharmaceuticals. 28 tabs., 5 figs.

Full Text Available Background: Acne vulgaris is a chronic inflammatory disease of the pilosebaceous units, which chiefly involves face and upper part of the trunk. Its prevalence is highest in adolescence, where the individual counters several psychosocial changes. Depression, suicidal thoughts, and low self esteem are reported in the patients with this disease. Aim: The goal of this study is to compare prevalence of anxiety and depression in the patients with acne vulgaris and normal population. Materials and Methods: In this cross-sectional study, 82 patients with acne vulgaris and 82 persons without acne who referred to a dermatology clinic and a specialized office for skin diseases in Rasht were studied. Anxiety and depression were evaluated by Hospital Anxiety and Depression Scale (HADS questionnaire and severity of acne was evaluated by Global Acne Grading System (GAGS. Data were analyzed by SPSS ver. 14.0 software, independent T-test, multi variate analysis of covariance (MANCOVA and chi-square test for comparison the quantitative and ordinal data, respectively; with α=0.05. Results: Prevalence of anxiety and mean of anxiety scores were 68.3% and 9.17 ± 3.52, respectively, in patients group and 39.1% and 7.10 ± 3.07, respectively, in control group in which there was a significant difference (P = 0.001. Prevalence of depression and mean of depression scores were 25.6% and 5.34 ± 3.29, respectively, in patients group and 28.1% and 5.01 ± 3.32, respectively, in control group in which there was no significant difference. Conclusion: According to high prevalence of anxiety in patients with acne vulgaris, assessment of the screening mental status of the patients by simple questionnaire such as HADS is suggested.

The assembly status of the cytochrome bc(1) complex has been analyzed in distinct yeast deletion strains in which genes for one or more of the bc(1) subunits were deleted. In all the yeast strains tested, a bc(1) sub-complex of approximately 500 kDa was found when the mitochondrial membranes were analyzed by blue native electrophoresis. The subsequent molecular characterization of this sub-complex, carried out in the second dimension by SDS/PAGE and immunodecoration, revealed the presence of the two catalytic subunits, cytochrome b and cytochrome c(1), associated with the noncatalytic subunits core protein 1, core protein 2, Qcr7p and Qcr8p. Together, these bc(1) subunits build up the core structure of the cytochrome bc(1) complex, which is then able to sequentially bind the remaining subunits, such as Qcr6p, Qcr9p, the Rieske iron-sulfur protein and Qcr10p. This bc(1) core structure may represent a true assembly intermediate during the maturation of the bc(1) complex; first, because of its wide distribution in distinct yeast deletion strains and, second, for its characteristics of stability, which resemble those of the intact homodimeric bc(1) complex. By contrast, the bc(1) core structure is unable to interact with the cytochrome c oxidase complex to form respiratory supercomplexes. The characterization of this novel core structure of the bc(1) complex provides a number of new elements clarifying the molecular events leading to the maturation of the yeast cytochrome bc(1) complex in the inner mitochondrial membrane.

Meadowsweet (Filipendula ulmaria (L.) Maxim.), and dropwort (Filipendula vulgaris Moench) flowers are traditionally used to treat various ailments, including inflammatory conditions. The aim of the present study was to validate the aforementioned ethnomedicinal claim by assessing antihyperalgesic and antiedematous activities and toxicity of orally administered lyophilized flower infusions (LFIs) of F. ulmaria and F. vulgaris in experimental animals. The phytochemical analysis of LFIs was performed by HPLC-DAD. Antihyperalgesic and antiedematous activities were estimated in a rat model of inflammation induced by intraplantar injection of carrageenan using Von Frey anesthesiometer and plethysmometer, respectively. Moreover, acute oral toxicity of LFIs in mice was evaluated by observing changes in animal behavior and mortality for a period of 14 days following the treatment. HPLC-DAD analysis revealed the presence of phenolic acids and flavonoids in LFIs, among which spiraeoside was identified as the principal component (56.27±1.03 and 55.67±1.82mg/g of LFI in F. ulmaria and F. vulgaris, respectively). The LFIs of F. ulmaria and F. vulgaris (100-300mg/kg; p.o.) produced significant and dose-dependent antihyperalgesic effects: ED 50 ±SEM values were 164.8±15.4mg/kg (110.3-246.3mg/kg) and 172.2±6.2mg/kg (147.4-201.3mg/kg) for F. ulmaria and F. vulgaris, respectively. On the other hand, LFIs of both species (100-300mg/kg; p.o.) did not significantly reduce edema. Good safety profiles were evidenced in the toxicological study. The median lethal dose (LD 50 ) of the tested extracts is likely to be greater than 2000mg/kg. The results of the present study support the use of F. ulmaria and F. vulgaris flowers in folk medicine for relieving pain in diseases with an inflammatory component.

Superficial chemical peels are frequently used in acne vulgaris treatment. Although glycolic acid (GA) has been widely used in clinical practice, its pH ranges from 0.08-2.75 and thus should be neutralized after application to avoid burns. To evaluate treatment efficacy and safety of chemical peeling using buffered 50% GA (pH 3.0) + 0.5% salicylic acid (SA) solution that does not need to be neutralized in the treatment of acne vulgaris compared to the conventional peeling using Jessner's solution. We performed a prospective, randomized, evaluator-blind, split-face clinical trial. Twenty patients were randomized by assigning one side of each patient's face to receive a 50% GA (pH 3.0) + 0.5% SA peel (GA side) and the other side to receive the Jessner's solution (Jessner's solution side). All patients underwent 2 sessions of treatment spaced 2 weeks apart. Lesion count, acne severity, subjective efficacy assessment, and side effects were evaluated. The total lesion count was significantly reduced for the GA and Jessner's solution sides (P .05). The GA side had fewer side effects than the Jessner's solution side. The results of this study suggest that chemical peeling using the 50% GA (pH 3.0) + 0.5% SA solution can be as effective and convenient as the conventional peeling using Jessner's solution in the treatment of acne vulgaris and may show fewer adverse events than the conventional peeling. © 2017 Wiley Periodicals, Inc.
Interaction of Al with O2 exposed Mo2BC

Highlights: • Al adheres to many surfaces. • Solid–solid interactions challenging for real (oxidized) surfaces. • Dissociative O 2 adsorption on Mo 2 BC(0 4 0). • Al nonamer is disrupted on oxidized Mo 2 BC(0 4 0). • Adhesion of a residual Al on the native oxide. - Abstract: A Mo 2 BC(0 4 0) surface was exposed to O 2 . The gas interaction was investigated using ab initio molecular dynamics and X-ray photoelectron spectroscopy (XPS) of air exposed surfaces. The calculations suggest that the most dominating physical mechanism is dissociative O 2 adsorption whereby Mo−O, O−Mo−O and Mo 2 −C−O bond formation is observed. To validate these results, Mo 2 BC thin films were synthesized utilizing high power pulsed magnetron sputtering and air exposed surfaces were probed by XPS. MoO 2 and MoO 3 bond formation is observed and is consistent with here obtained ab initio data. Additionally, the interfacial interactions of O 2 exposed Mo 2 BC(0 4 0) surface with an Al nonamer is studied with ab initio molecular dynamics to describe on the atomic scale the interaction between this surface and Al to mimic the interface present during cold forming processes of Al based alloys. The Al nonamer was disrupted and Al forms chemical bonds with oxygen contained in the O 2 exposed Mo 2 BC(0 4 0) surface. Based on the comparison of here calculated adsorption energy with literature data, Al−Al bonds are shown to be significantly weaker than the Al−O bonds formed across the interface. Hence, Al−Al bond rupture is expected for a mechanically loaded interface. Therefore the adhesion of a residual Al on the native oxide layer is predicted. This is consistent with experimental observations. The data presented here may also be relevant for other oxygen containing surfaces in a contact with Al or Al based alloys for example during forming operations

The effects of lectins in the diet have been mainly studied in rats. An important question is whether results obtained in rats can be extrapolated to larger animals like the pig. Phaseolus vulgaris beans are rich in toxic lectins. Therefore a study was carried out to compare the effects of diets
Influence of cysteine and selenodicysteine on the uptake of zinc by Chlorella vulgaris Beijerinck

1982-01-01

The uptake of zinc labelled with radioactive 65 Zn in the presence of cysteine and selenodicysteine by Chlorella vulgaris was examined. The concentration of zinc ions in the medium was 20 mg per 1. The uptake yield was found to be enhanced by selenodicysteine. At concentration of 10 - 7 -10 - 6 M the growth rate of Chlorella vulgaris was accelerated by the latter, provided that the specific activity of 65 Zn was 3.7 MBq/1. At this specific zinc activity cysteine increased the uptake yield during the initial 50 h of the incubation process. At specific 65 Zn-activity of 55.5 MBq/1 selenodicysteine and cysteine only slightly influenced the zinc uptake by Chlorella vulgaris. No increment in the biomass was observed at this specific zinc radioactivity. (author)

Sixteen pony foals were reared worm-free and inoculated with Strongylus vulgaris. On day 7 after inoculation, 12 ponies were given a fenbendazole 10% suspension at dose rate of 50 mg/kg of body weight by stomach tube. On day 8 after inoculation, 8 of these ponies were given the 2nd treatment of the anthelmintic and on day 9, 4 of these ponies were given the 3rd treatment. (The other 4 of the 16 ponies were given only tap water, as controls.) The ponies were necropsied at death or on day 28 after inoculation. Fenbendazole was effective in minimizing the appearance of clinical signs associated with acute arteritis and was highly efficacious in eliminating early 4th-stage S vulgaris larvae in ponies treated for 3 consecutive days (ie, days 7, 8, and 9). After administration of the anthelmintic, clinical signs of toxicosis were not observed.

Strongylus vulgaris is a pathogenic helminth parasite infecting horses and was once considered to be the primary cause of colic. Migrating larvae cause ischaemia and infarction of intestinal segments. This knowledge is derived from case reports and experimental inoculations of parasite-naïve foals, and it remains unknown to what extent the parasite is associated with different types of colic. To evaluate the role of S. vulgaris as a risk factor for different types of colic in horses. A retrospective case-control study among horses referred with abdominal pain to the University of Copenhagen Large Animal Teaching Hospital during 2009-2011. Each colic case was matched with an equid of the same type (pony, Warmblooded or Coldblooded), age, sex and admitted in the same month and year but for problems unrelated to the gastrointestinal tract. Serum samples were analysed for antibodies to migrating S. vulgaris larvae using a recently developed enzyme-linked immunosorbent assay (ELISA). The following 4 case definitions were used: colic sensu lato, i.e. all horses presenting with colic (n = 274), with further subgroups, i.e. undiagnosed colics (n = 48), strangulating obstructions (n = 76) and nonstrangulating infarctions (n = 20). Strongylus vulgaris antibody levels were similar to control values in colics sensu lato and horses with undiagnosed colic. In contrast, nonstrangulating intestinal infarctions were significantly associated with positive S. vulgaris ELISAs (odds ratio 5.33, 95% confidence interval 1.03-27.76, P = 0.05). Also, horses with nonstrangulating infarctions had a significantly higher occurrence of positive ELISAs than horses with strangulating obstructions (odds ratio 3.79, 95% confidence interval 1.34-10.68, P = 0.01) and the colic sensu lato group (odds ratio 3.09, 95% confidence interval 1.20-8.01, P = 0.02). Nonstrangulating intestinal infarction was strongly associated with S. vulgaris-specific antibodies, whereas the more broadly defined

Using the $pp$ collision data collected by LHCb at center-of-mass energies $\\sqrt{s} \\, = 7 \\, {\\rm TeV} \\,$ and $8 \\, {\\rm TeV} \\,$, corresponding to an integrated luminosity of $3 \\, \\mathrm{fb}^{-1} \\,$, the ratio of the branching fraction of the $B_{c}^{+} \\to \\psi(2S)\\pi^+$ decay relative to that of the $B_{c}^{+} \\to J/\\psi\\pi^+$ decay is measured to be ${0.268 \\pm 0.032\\mathrm{\\,(stat)} \\pm 0.007\\mathrm{\\,(syst)} \\pm 0.006\\,(\\mathrm{BF}) }$. The first uncertainty is statistical, the second is systematic, and the third is due to the uncertainties on the branching fractions of the $J/\\psi \\to \\mu^{+}\\mu^{-}$ and $\\psi(2S) \\to \\mu^{+}\\mu^{-}$ decays. To enhance the signal significance with limited $B_{c}^{+}$ statistics, the boosted decision tree selection is used to separate the signal and background effectively. The systematic uncertainties are discussed extensively. This measurement is consistent with the previous LHCb result, and the statistical uncertainty is halved.

Physiological and functional properties of lipid droplet-associated proteins in algae remain scarce. We report here the caleosin gene from Chlorella vulgaris encodes a protein of 279 amino acid residues. Amino acid sequence alignment showed high similarity to the putative caleosins from fungi, but less to plant caleosins. When the C. vulgaris TISTR 8580 cells were treated with salt stress (0.3 M NaCl), the level of triacylglycerol increased significantly. The mRNA contents for caleosin in Chlorella cells significantly increased under salt stress condition. Caleosin gene was expressed in E. coli. Crude extract of E. coli cells exhibited the cumene hydroperoxide-dependent oxidation of aniline. Absorption spectroscopy showed a peak around 415 nm which was decreased upon addition of cumene hydroperoxide. Native polyacrylamide gel electrophoresis suggests caleosin existed as the oligomer. These data indicate that a fresh water C. vulgaris TISTR 8580 contains a salt-induced heme-protein caleosin.

In this study, Chlorella vulgaris (C. vulgaris) were cultured in cell culture flask supplied with intermittent CO 2 enriched gas. The impact of CO 2 concentration (from 1% to 20% v/v) on the growth of C. vulgaris cultured in domestic wastewater was exploited in various perspectives which include biomass, specific growth rate, culture pH, carbon consumption, and the removal of nitrogen and phosphorus compounds. The results showed that the maximum microalgal biomass concentration, 1.12 g L -1 , was achieved with 10% CO 2 as a feed gas. At 20% CO 2 the growth of C. vulgaris suffered from inhibition during initial 1.5 d, but acclimated to low pH (6.3 in average) with relatively higher specific growth rate (0.3-0.5 d -1 ) during subsequent culture period. After the rapid consumption of ammonium in the wastewater, an obvious decline in the nitrate concentration was observed, indicating that C. vulgaris prefer ammonium as a primary nitrogen source. The total nitrogen and phosphorus decreased from 44.0 mg L -1 to 2.1-5.4 mg L -1 and from 5.2 mg L -1 to 0-0.6 mg L -1 within 6.5 d under the aeration of 1-20% CO 2 , respectively, but no significant difference in consumed nitrogen versus phosphorus ratio was observed among different CO 2 concentration. The kinetics of nutrients removal were also determined through the application of pseudo first order kinetic model. 5-10% CO 2 aeration was optimal for the growth of C. vulgaris in the domestic wastewater, based on the coupling of carbon consumption, microalgal biomass, the nutrients removal and kinetics constants.

A flare for decommissioning : a push to close flare pits in B.C. earns Petro-Canada an industry award for environmental stewardship

Energy Technology Data Exchange (ETDEWEB)

Mahoney, J.

2009-01-15

Flaring is widely used to dispose of natural gas liberated during oil production and processing in remote areas where there is no pipeline on site to make use of the gas. Sources of flaring include well testing, solution gas from oil wells, underbalanced drilling, gas gathering systems and gas processing plants. Flaring is a source of pollution and a waste of energy. This article described Petro-Canada's efforts to eliminate flaring. In the late 1990s, the company began environmental assessments of its flare pits in British Columbia (BC). Since 2005, the producer has decommissioned 106 of its 108 pits in the province and ring-fenced the other 2. As the staff advanced the task of decommissioning, it often consolidated flaring hardware, installing a single, vertical flare stack to serve where 3 or 4 flare pits had previously served as many well sites. Before decommissioning began, Petro-Canada carried out its own environmental protocol and assessed its pits for the presence of contaminants and for their potential to leach into local waterways. Monitoring of groundwater through wells drilled on the company's BC flare pit sites will continue for some time, particularly on sites with bodies of water. BC's Oil and Gas Commission estimated that between 1996 and 2006, conservation of solution gas rose from 87 to 97 per cent among the province's producers. Petro-Canada was commended for being among the first to secure all flare pits under its control in BC. It was estimated that 49 per cent of all flare pits decommission in BC by 2007 were completed by Petro-Canada. 2 refs., 2 figs.

Full Text Available Nonylphenol polyethoxylates (NPnEOs, a major class of nonionic surfactants, can easily enter into aquatic environments through various pathways due to their wide applications, which leads to the extensive existence of their relative stable metabolites, namely nonylphenol (NP and mono- to tri-ethoxylates. This study investigated the bioconcentration and degradation of NP and NPnEO oligomers (n = 1–12 by a green algae, Chlorella vulgaris. Experimental results showed that C. vulgaris can remove NP from water phase efficiently, and bioconcentration and degradation accounted for approximately half of its loss, respectively, with a 48 h BCF (bioconcentration factor of 2.42 × 103. Moreover, C. vulgaris could concentrate and degrade NPnEOs, distribution profiles of the series homologues of the NPnEOs in algae and water phase were quite different from the initial homologue profile. The 48 h BCF of the NPnEO homologues increased with the length of the EO chain. Degradation extent of total NPnEOs by C. vulgaris was 95.7%, and only 1.1% remained in water phase, and the other 3.2% remained in the algal cells. The algae removed the NPnEOs mainly through degradation. Due to rapid degradation, concentrations of the long chain NPnEO homologous in both water (n ≥ 2 and the algal phase (n ≥ 5 was quite low at the end of a 48 h experiment.

To observe the Koch phenomenon of Mycobacterium tuberculosis(MTB)-infected guinea pigs after vaccinated with killed H37Ra bacteria or tuberculosis vaccine candidate AEC/BC02. Eighteen guinea pigs were challenged subcutaneously with 5.0×10(3) CFU MTB and after 40 days were divided into 3 groups (6 per group): NS group, AEC/BC02 group and H37Ra group, which were injected intramuscularly 3 times at 1 day interval with normal saline, AEC/BC02 vaccine and killed H37Ra bacteria respectively. Three weeks after the first vaccination, all guinea pigs were sacrificed to evaluate gross pathological scores for liver, spleen and lung, bacterial loads in lung and spleen, and lung inflammation. The gross pathological score in H37Ra group (48±26) was lower than that in NS group(62±15), but the difference was not significant (t=1.093, P=0.300). The AEC/BC02 group had a significantly lower gross pathological score (36±15) than NS group (t=2.980, P=0.014). No significant difference between H37Ra group and AEC/BC02 group was observed (t=1.009, P=0.337). The spleen bacterial load [(5.31±0.80) log10 CFU]in H37Ra group was slightly lower than that in NS group[(5.57±0.75) log10 CFU] but the difference was not significant (t=1.581, P=0.574). In AEC/BC02 group bacterial load in the spleen was (4.64±0.64) log10 CFU and significantly lower than NS group (t=2.306, P=0.044) and no significant difference between H37Ra group and AEC/BC02 group was observed (t=1.602, P=0.140). Meanwhile, the lung bacterial load in AEC/BC02 group was (3.71±1.01) log10 CFU and in H37Ra group was (3.82±1.25) log10 CFU. Compared to (4.15±0.69) log10 CFU in the NS group, no significant differences were found (t=0.881, P=0.399; t=0.566, P=0.584, respectively). For the lung inflammation, the inflamed areas in H37Ra group were significantly larger [(33.0±4.4%)] than those in both NS group [(14.8±8.4) %, t=4.719, P=0.001] and AEC/BC02 group [(14.8±8.4) %, t=3.616, P=0.005], and no significant differences were

Acne vulgaris, a multi-factorial disease, is one of the most common skin diseases, affecting an estimated 80% of Americans at some point during their lives. The gram-positive and anaerobic Propionibacterium acnes (P. acnes) bacterium has been implicated in acne inflammation and pathogenesis. Therapies for acne vulgaris using antibiotics generally lack bacterial specificity, promote the generation of antibiotic-resistant bacterial strains, and cause adverse effects. Immunotherapy against P. acnes or its antigens (sialidase and CAMP factor) has been demonstrated to be effective in mice, attenuating P. acnes-induced inflammation; thus, this method may be applied to develop a potential vaccine targeting P. acnes for acne vulgaris treatment. This review summarizes reports describing the role of P. acnes in the pathogenesis of acne and various immunotherapy-based approaches targeting P. acnes, suggesting the potential effectiveness of immunotherapy for acne vulgaris as well as P. acnes-associated diseases.

Ten helminth-free pony foals divided into three groups were used in this study. Eight foals were each experimentally infected per os with 50 Strongylus vulgaris infective larvae weekly for 4 weeks, at which time one foal died of acute verminous arteritis. The remaining seven foals subsequently received 50 S. vulgaris infective larvae every 2 weeks for an additional 20 weeks. Four of the infected foals remained untreated (Group 1) and three of the infected foals were given ivermectin at 8, 16 and 24 weeks post initial infection (Group 2). Two foals served as controls (Group 3). Foals in Group 1 developed eosinophilia, which was sustained throughout the course of infection. A mild eosinophilia also developed in Group 2 foals; however, the eosinophil numbers were markedly reduced for 3 weeks after each ivermectin treatment. Only foals in Group 1 developed significant (P less than 0.05) hyperproteinemia, hyperbetaglobulinemia and a reversal of the albumin/globulin (A/G) ratio 4 weeks after initial infection. Significant (P less than 0.05) IgG anti-S. vulgaris ELISA titers developed in foals in Groups 1 and 2 3 weeks after infection and were sustained for the duration of the experiment. Western blot analysis of soluble somatic antigens of S. vulgaris adult female and male worms probed with sera from foals in Groups 1 and 2 revealed only subtle differences between these animals. The blastogenic reactivity of peripheral blood mononuclear cells (PBMC) to phytohemagglutinin and concanavalin A was not significantly different between groups. Peripheral blood mononuclear cells from foals in Groups 1 and 2 developed significant (P less than 0.05) blastogenic reactivity to S. vulgaris soluble adult somatic antigen when examined at 25 weeks after infection. Mesenteric lymph node cells from foals in Group 2, although not statistically significant, were more reactive to antigen than were the mesenteric lymph node cells from foals in Group 1 when examined at 27 weeks after infection
A new era of prosperity through power : maintaining BC's competitive advantage

International Nuclear Information System (INIS)

Potts, D.

2001-01-01

The availability of abundant low cost electric power has been a driving force behind British Columbia's economic growth. BC's low cost power resources can create a natural competitive economic advantage for the province. Electricity, as a publicly owned resource can offer many competitive advantages for business in British Columbia, if managed correctly. However, it was noted that meaningful economic advantages can only be realized if the existing power resources in the province are operated efficiently and priced at or close to cost. In the 1980s, the Joint Industry Electricity Steering Committee (JIESC) was formed following the regulation of BC Hydro by BC Utilities Commission. It became clear that maintaining low rates for electricity was a public issue that needed input from other governmental forums if JIESC was to be successful. The major sectors represented by JIESC include pulp and paper, mining, and electrochemicals. This paper listed each member company. In order to turn BC's economy around and re-establish the province as a leading economy in Canada, the following recommendations have been proposed for the short term: (1) maintain an ample supply of low cost power for the future, (2) remove the provincial sales tax on the purchase of electric power used for manufacturing and processing, (3) extend the current rate freeze, (4) initiate a long-term resource acquisition and transmission expansion strategy to assure the availability of ample supplies of low cost power. Recommendations for the long term include: (1) maintain regulated cost based rates, (2) develop ample low cost power, (3) utilize downstream benefits, (4) provide a role for the private sector, (5) maintain adequate transmission facilities, (6) reduce government revenues, and (7) instill customer driven management. 3 figs

The aim of this study is to evaluate the frequency of dosing topical antibiotics as monotherapy in the treatment of acne vulgaris, and physician specialty prescribing these medications. This study is a retrospective review of all visits with a sole diagnosis of acne vulgaris (ICD-9-CM code 706.1) found on the National Ambulatory Medical Care Survey (NAMCS) in 1993-2010. We recorded the number of visits surveyed where acne vulgaris was the sole diagnosis, number of visits where topical antibiotics were the only treatment prescribed, and the specialty of physician in each encounter. Topical erythromycin or clindamycin were the sole medication prescribed in 0.81% of the visits recorded, with 60% of these prescriptions arising from dermatologists and 40% from non-dermatologists. The trend of prescribing topical antibiotic monotherapy is declining (p acnes to topical antibiotic regimens has led to the need to re-evaluate the use of topical antibiotics in the treatment of acne vulgaris. While the rate of topical antibiotic monotherapy is declining, their use should be reserved for situations where the direct need for antibiotics arises. If a clinician feels that antibiotics are a necessary component to acne therapy, they should be used as part of a combination regimen.

Photon up-conversion, a process whereby lower energy radiations are converted to higher energy levels via the use of appropriate phosphor systems, was employed as a novel strategy for improving microalgal growth and lipid productivity. Photon up-conversion enables the utilization of regions of the solar spectrum, beyond the typical photosynthetically active radiation, that are usually wasted or are damaging to the algae. The effects of up-conversion of red light by two distinct sets of up-conversion phosphors were studied in the model microalgae Chlorella vulgaris. Up-conversion by set 1 phosphors led to a 2.85 fold increase in biomass concentration and a 3.2 fold increase in specific growth rate of the microalgae. While up-conversion by set 2 phosphors resulted in a 30% increase in biomass and 12% increase in specific intracellular neutral lipid, while the specific growth rates were comparable to that of the control. Furthermore, up-conversion resulted in higher levels of specific intracellular reactive oxygen species in C. vulgaris. Up-conversion of red light (654 nm) was shown to improve biomass yields in C. vulgaris. In principle, up-conversion can be used to increase the utilization range of the electromagnetic spectrum for improved cultivation of photosynthetic systems such as plants, algae, and microalgae.

miR-34b/c Regulates Wnt1 and Enhances Mesencephalic Dopaminergic Neuron Differentiation

Directory of Open Access Journals (Sweden)

Roberto De Gregorio

2018-04-01

Full Text Available Summary: The differentiation of dopaminergic neurons requires concerted action of morphogens and transcription factors acting in a precise and well-defined time window. Very little is known about the potential role of microRNA in these events. By performing a microRNA-mRNA paired microarray screening, we identified miR-34b/c among the most upregulated microRNAs during dopaminergic differentiation. Interestingly, miR-34b/c modulates Wnt1 expression, promotes cell cycle exit, and induces dopaminergic differentiation. When combined with transcription factors ASCL1 and NURR1, miR-34b/c doubled the yield of transdifferentiated fibroblasts into dopaminergic neurons. Induced dopaminergic (iDA cells synthesize dopamine and show spontaneous electrical activity, reversibly blocked by tetrodotoxin, consistent with the electrophysiological properties featured by brain dopaminergic neurons. Our findings point to a role for miR-34b/c in neuronal commitment and highlight the potential of exploiting its synergy with key transcription factors in enhancing in vitro generation of dopaminergic neurons. : In this article, Bellenchi and colleagues show that the microRNA miR-34b/c is expressed in FACS-purified Pitx3-GFP+ neurons and promotes dopaminergic differentiation by negative modulating Wnt1 and the downstream WNT signaling pathway. Induced dopaminergic cells, expressing miR-34b/c, synthesize dopamine and show the electrophysiological properties featured by brain dopaminergic neurons.

2014-09-01

Full Text Available Four visual censuses targeting Octopus vulgaris living in dens on sandy bottoms were carried out from June to October 2013 in the National Park of the Atlantic Galician Islands (NW Spain. Censuses were undertaken by scuba diving between 5 and 21 m depth in daytime. The total area swept was 13.75 ha. There were no significant differences between octopus presence in dens during open and closed fishing seasons. Depth had a significant negative relationship with occupancy. The average number of dens per 1000 m2 was 3.84±0.84 in June and 3.89 in October. The area per den was 260 m2. Den number estimations varied between 1586 and 2057. The largest number of dens (76.5% was found between 5 and 10 m depth. Den distribution was clumped. No significant differences were found between octopus size classes (small, medium and large and den diameter. Associate dens were observed. There were no significant differences in den diameter and shell types found around the middens. Many dens could be “permanent”. Drilling bivalve shell behaviour is discussed. The surveyed area had around 1100 individuals, mainly small specimens. No significant differences were found between octopus size and depth. Substrate, den type and food abundance and availability (especially razors Ensis arcuatus seem to be the main factors influencing dens and octopus density and distribution. Den availability does not appear to be a limiting factor in this case. Temperature, den availability, predators and fishing pressure influencing density and distribution are discussed. Rodas inlet may be a preferential habitat for O. vulgaris individuals ranging from 200 to 2000 g, but especially small specimens ( ≤ 1000 g.

1981-07-01

Rabbit antisera were prepared against veronal buffered saline extracts of L4 and L5 Strongylus vulgaris, adult S. vulgaris and adult Strongylus equinus retrieved from naturally infected horses. In agar gel diffusion with these antisera, adult S vulgaris and S. equinus each appeared to have at least one unique antigen; larval S. vulgaris appeared to have two species-specific and two stage-specific antigens. There were several common antigens. Excretory and secretory products were collected also from L4 and L5 an maintained over several days in tissue culture fluid. In agar gel diffusion against the above rabbit antisera, a stage-specific antigen was found also in excretory and secretory products. In addition, excretory and secretory products had three antigens in common with adult and larval S. vulgaris, but only one of these was common to adult S. equinus. The excretory and secretory products appear, therefore, to have two species-specific and one stage-specific antigens.

Ghrelin in the pilosebaceous tissues of human skin and ghrelin levels in patients with acne vulgaris have not yet been investigated. The purpose of this study was to screen ghrelin immunoreactivity by immunohistochemistry in human pilosebaceous tissues of human skin and also to determine the quantities of ghrelin in the serum of the patients with acne vulgaris. 30 patients presenting with acne vulgaris and 30 control subjects participated in this study. Ghrelin levels were determined by enzyme linked immunosorbent assay (ELISA). Human hair follicles and sebaceous glands were immunohistochemically examined. Immunohistochemistry results showed that there is a strong ghrelin immunoreactivity in the hair follicles and sebaceous glands in sections of human skin. The mean serum ghrelin levels (27.58 ・} 15.44 pg/mL) in patients with acne vulgaris was significantly lower than those of controls (35.62・}20.46 pg/mL). Ghrelin produced in hair follicles and sebaceous glands of the skin might participate in the pathogenesis of acne vulgaris and also acne vulgaris in humans might be associated with decreased serum ghrelin.

The precipitin response of the mitogen produced by Strongylus vulgaris arterial larvae was investigated. IgG (T) from the sera of horses naturally infected with S. vulgaris adults and arterial larvae recognised the presence of two antigenic components of the mitogenic fractions. The results obtained seem to confirm that these antigens are immunogenic in stimulating the production of increased levels of IgG(T) in infected animals, and showed that the procedures could be used as immunological tools in the diagnosis of S. vulgaris infection.
Changes in serum Strongylus vulgaris-specific antibody concentrations in response to anthelmintic treatment of experimentally-infected foals

Directory of Open Access Journals (Sweden)

Martin Krarup Nielsen

2015-07-01

Full Text Available Strongylus vulgaris is the most pathogenic nematode parasite of horses. Its extensive migration in the mesenteric blood vessels can lead to life-threatening intestinal infarctions. Recent work has shown that this parasite is still identified among managed horse populations. A serum enzyme-linked immunosorbent assay (ELISA has been developed for the detection of migrating larvae of S. vulgaris. Previous work has documented an increase in ELISA values following larvicidal treatment with ivermectin and suggested that the target parasite antigen is primarily produced by the later larval stages. The aim of this study was to experimentally inoculate cohorts of foals with S. vulgaris, and then compare ELISA responses to early or later ivermectin treatments. Fifteen foals were held in confinement and infected orally with ~ 25 S. vulgaris third-stage larvae on days 0, 7, 14, and 21. Foals were weaned on Day 43 and turned out to a pasture not previously grazed by horses. Foals remained at pasture continuously until the study was terminated on Day 196. On Day 55, foals were randomly allocated to three treatment groups of five each. Group 1 received ivermectin on Day 56, Group 2 received ivermectin on Day 112, and Group 3 foals served as untreated controls. Serum and fecal samples were collected at 28-day intervals throughout the study. Serum samples were analyzed with the S. vulgaris-specific ELISA and fecal samples were processed for fecal egg counting. The ELISA values of Group 1 foals were significantly lower than Groups 2 or 3 on days 140-196. Both treated groups exhibited increased ELISA values following ivermectin treatment. Results indicate that the target diagnostic antigen is produced throughout the course of arterial infection with S. vulgaris, but that an early ivermectin treatment can reduce the cumulative antigen produced over the course of an infection.

Strongylus vulgaris is the most pathogenic nematode parasite of horses. Its extensive migration in the mesenteric blood vessels can lead to life-threatening intestinal infarctions. Recent work has shown that this parasite is still identified among managed horse populations. A serum enzyme-linked immunosorbent assay (ELISA) has been developed for the detection of migrating larvae of S. vulgaris. Previous work has documented an increase in ELISA values following larvicidal treatment with ivermectin and suggested that the target parasite antigen is primarily produced by the later larval stages. The aim of this study was to experimentally inoculate cohorts of foals with S. vulgaris, and then compare ELISA responses to early or later ivermectin treatments. Fifteen foals were held in confinement and infected orally with ~25 S. vulgaris third-stage larvae on Days 0, 7, 14, and 21.

Five weanling ponies were subjected to an intensive 6-week deworming program after which 4 Ag-AgCl bipolar electrodes were implanted surgically on the distal ileum. For 3 hours each day for 5 consecutive days, ileal myoelectrical activity was recorded from fed ponies under 3 sequential conditions: preinoculation, after oral administration of 1,000 killed Strongylus vulgaris infective larvae (3 ponies), and after oral administration of 1,000 live S vulgaris infective larvae. Recordings were analyzed for slow wave frequency, percentage duration of phases I, II, and III of the migrating myoelectrical complex (MMC), and the frequency of distinct, rapidly migrating action-potential complexes within phase 2 of the MMC. After administration of live and killed infected 3rd-stage larvae, there was a marked increase in the number of disrupted phase III complexes, and a significant (P less than 0.001) increase in the number of migrating action-potential complexes. In addition, after inoculation of live 3rd-stage larvae, there was a significant increase (P less than 0.001) in the percentage of time that the MMC was occupied by prolonged periods devoid of spike activity (phase I). The results indicate that S vulgaris larval mucosal penetration and submucosal migration can cause changes in ileal myoelectrical activity that could cause colic, and that larval antigen alone within the lumen may disrupt ileal motility.

2002-08-01

British Columbia Hydro (BC Hydro) published this document which measures the environmental, social and economic performance of the company. It is a complement to BC Hydro's 2002 Annual Report. The report was prepared to better understand the company's business in terms of its commitment to being an environmentally, socially, and economically responsible company (the three bottom lines). BC Hydro proved its ability to integrate the three bottom lines in decision making processes by carefully examining the environmental, social and economical impacts of programs such as Power Smart, Green and Alternative Energy, and Water Use Planning. All indicators point to BC Hydro achieving its commitment of providing a minimum of 10 per cent of new demand through 2010 with new green energy sources. Water Use Plans were developed for hydroelectric generating stations, and they should all be in place by 2003. Efficiencies realised through the Power Smart program offset the increases in greenhouse gas associated with increased energy demand. Juvenile sturgeon raised in a hatchery were released into the Columbia River in May 2002. The completion of a 40-kilometre trail on the Sunshine Coast was helped by a financial contribution from BC Hydro in the amount of 23,000 dollars. Safety improvements were implemented at eight facilities, such as dam remediation, dam surveillance and instrumentation updates. Scholarships were awarded across the province, along with additional donations to non-profit organizations. Co-op positions were provided for 150 students. Internal energy efficiency programs were successful. Planning is under way for significant maintenance work and equipment replacement projects as the transmission and distribution infrastructure ages. The number of reported indicators was expanded this year. In turn, they were aligned with the revised Global Reporting Initiative (GRI) guidelines. tabs
BC's oil and gas industry : opportunities and challenges

International Nuclear Information System (INIS)

Alvarez, P.

2003-01-01

An update of the Canadian petroleum and natural gas industry was presented with reference to activity trends and major issues. The presentation also described opportunities and challenges facing the industry in British Columbia and reviewed the impact of federal policies on BC. In recent years the industry has moved to oil sands and unconventional gas, offshore sites, and coalbed methane development. Other changes are a result of technology which makes it possible to drill deeper and faster while having less environmental impact. Government issues have become increasingly complex, however. Industry capital spending from 2000 to 2003 was presented for Northern Canada, the east coast offshore, Alberta, the Western Canada Sedimentary Basin, oil sand deposits, and international activities. The presentation included several graphs depicting: the changing natural gas production mix; North American natural gas demand; wells drilled by province; natural gas resources in BC; upstream capital spending in BC; wells drilled by type and depth in BC; top natural gas wells in 2000 and 2002; natural gas production in BC; finding and development costs for Canadian natural gas; and, the widening gap of the federal income tax rate between oil and natural gas and other industries. British Columbia is in the strategic position of having significant untapped gas potential in the northeastern part of the province. For now, there is sufficient pipeline capacity to bring the gas to markets in the United States where there is a strong demand for electric power generation. 16 figs
Identification of Small RNAs in Desulfovibrio vulgaris Hildenborough

Desulfovibrio vulgaris is an anaerobic sulfate-reducing bacterium capable of facilitating the removal of toxic metals such as uranium from contaminated sites via reduction. As such, it is essential to understand the intricate regulatory cascades involved in how D. vulgaris and its relatives respond to stressors in such sites. One approach is the identification and analysis of small non-coding RNAs (sRNAs); molecules ranging in size from 20-200 nucleotides that predominantly affect gene regulation by binding to complementary mRNA in an anti-sense fashion and therefore provide an immediate regulatory response. To identify sRNAs in D. vulgaris, a bacterium that does not possess an annotated hfq gene, RNA was pooled from stationary and exponential phases, nitrate exposure, and biofilm conditions. The subsequent RNA was size fractionated, modified, and converted to cDNA for high throughput transcriptomic deep sequencing. A computational approach to identify sRNAs via the alignment of seven separate Desulfovibrio genomes was also performed. From the deep sequencing analysis, 2,296 reads between 20 and 250 nt were identified with expression above genome background. Analysis of those reads limited the number of candidates to ∼87 intergenic, while ∼140 appeared to be antisense to annotated open reading frames (ORFs). Further BLAST analysis of the intergenic candidates and other Desulfovibrio genomes indicated that eight candidates were likely portions of ORFs not previously annotated in the D. vulgaris genome. Comparison of the intergenic and antisense data sets to the bioinformatical predicted candidates, resulted in ∼54 common candidates. Current approaches using Northern analysis and qRT-PCR are being used toverify expression of the candidates and to further develop the role these sRNAs play in D. vulgaris regulation.

Full Text Available The microalgae biomass production from textile waste effluent is a possible solution for the environmental impact generated by the effluent discharge into water sources. The potential application of Chlorella vulgaris for bioremediation of textile waste effluent (WE was investigated using 22 Central Composite Design (CCD. This work addresses the adaptation of the microalgae C. vulgaris in textile waste effluent (WE and the study of the best dilution of the WE for maximum biomass production and for the removal of colour and Chemical Oxygen Demand (COD by this microalga. The cultivation of C. vulgaris, presented maximum cellular concentrations Cmax and maximum specific growth rates μmax in the wastewater concentration of 5.0% and 17.5%, respectively. The highest colour and COD removals occurred with 17.5% of textile waste effluent. The results of C. vulgaris culture in the textile waste effluent demonstrated the possibility of using this microalga for the colour and COD removal and for biomass production. There was a significant negative relationship between textile waste effluent concentration and Cmax at 0.05 level of significance. However, sodium bicarbonate concentration did not significantly influence the responses of Cmax and the removal of colour and COD.

Evidence has accumulated that changes in intracellular signaling downstream of desmoglein 3 (Dsg3) may have a significant role in epithelial blistering in the autoimmune disease pemphigus vulgaris (PV). Currently, most studies on PV involve passive transfer of pathogenic antibodies into neonatal mice that have not finalized epidermal morphogenesis, and do not permit analysis of mature hair follicles (HFs) and stem cell niches. To investigate Dsg3 antibody-induced signaling in the adult epidermis at defined stages of the HF cycle, we developed a model with passive transfer of AK23 (a mouse monoclonal pathogenic anti-Dsg3 antibody) into adult 8-week-old C57Bl/6J mice. Validated using histopathological and molecular methods, we found that this model faithfully recapitulates major features described in PV patients and PV models. Two hours after AK23 transfer, we observed widening of intercellular spaces between desmosomes and EGFR activation, followed by increased Myc expression and epidermal hyperproliferation, desmosomal Dsg3 depletion, and predominant blistering in HFs and oral mucosa. These data confirm that the adult passive transfer mouse model is ideally suited for detailed studies of Dsg3 antibody-mediated signaling in adult skin, providing the basis for investigations on novel keratinocyte-specific therapeutic strategies.

Full Text Available Background & Aim: considering the use of Beberis vulgaris in traditional medicine as a blood sugar depressant, in this study, the effect of Beberis vulgaris extracts were investigated on the level of insulin secretion from islets isolated of langerhans in male mice. Methods: This experimental study was carried out on 90 adult male mice, NMARI strains weighing 20-25 g. Pancreatic islets from normal mice were isolated by collagenase digestion method. Then the aqueous and hydro-alcoholic extract of Beberis vulgaris at 0.05, 0.1, and 1 mg/ml concentrations and glyburide at 1 and 10 μM concentrations were applied on islets isolated in three different concentration of glucose solution (2.8, 5.6 and 16.7 mM. Insulin secretion from hand-picked islets were evaluated in the static incubation system. The level of Insulin secretion was measured by the ELISA insulin kit. Data were analyzed with variance analysis. Results: Insulin secretion was significantly increased at 16.7 mM glucose concentration in comparison with 2.8 and 5.6 mM glucose concentration (p<0.05. Incubation of pancreatic islets isolated at 2.8 and 5.6 mM glucose concentration and low concentrations of extract (0.05 and 0.1mg/ml significantly increased the insulin secretion (p<0.05. Glyburide at 10 μM concentration was more effective than aqueous and hydro alcoholic extract of Beberis vulgaris at 16.7 mM glucose. Conclusion: The present study supported the anti-diabetic effect of Beberis vulgaris extracts in vitro with low glucose concentration and it suggests that one of the anti diabetic mechanisms of this plant is via pancreatic islets.

Liquid swine manure was subjected to thermophilic anaerobic digestion, ammonia stripping and centrifugation in order to increase the available carbon sources and decrease the ammonia concentration and turbidity. Chlorella vulgaris (UTEX 2714) was grown on minimally diluted (2×, 3× and 4×) autoclaved and non-autoclaved pretreated anaerobic digestion swine manure (PADSM) in a batch-culture system for 7days. Results showed that C. vulgaris (UTEX 2714) grew best on 3× PADSM media, and effectively removed NH 4 + -N, TN, TP and COD by 98.5-99.8%, 49.2-55.4%, 20.0-29.7%, 31.2-34.0% and 99.8-99.9%, 67.4-70.8%, 49.3-54.4%, 73.6-78.7% in differently diluted autoclaved and non-autoclaved PADSM, respectively. Results of chemical compositions indicated that contents of pigment, carbohydrate, protein and lipid in C. vulgaris (UTEX 2714) changed with the culture conditions. Moreover, its fatty acid profiles suggested that this alga could be used as animal feed if cultivated in autoclaved PADSM or as good-quality biodiesel feedstock if cultivated in non-autoclaved PADSM.

The structural stability, electronic structure, elasticity, and optical properties of four types of monolayer BC{sub 2}N have been investigated from first principles using calculation based on density functional theory. The results show that the structural stability of BC{sub 2}N increases with the number of C–C and B–N bonds. By calculating the two-dimensional Young's modulus, shear modulus, Poisson's ratio, and shear anisotropic factors in different directions, four structures present various anisotropies and the most stable structure is almost isotropic. For C-type BC{sub 2}N, the values of two-dimensional Young's modulus, shear modulus, and bulk modulus (309, 128, 195 GPa m{sup −1}), are smaller than those of graphene (343, 151, 208) but bigger than those of h-BN (286, 185, 116). Furthermore, the dielectric function, refractive index, reflectivity, absorption coefficient, and energy loss spectrum are also calculated to investigate the mechanism underpinning the optical transitions in BC{sub 2}N, revealing monolayer BC{sub 2}N as a candidate window material. - Graphical abstract: Schematic diagram of BC{sub 2}N under the biaxial tensile strain.

Remedial investigation/feasibility study work plan for the 100-BC-2 operable unit, Hanford Site, Richland, Washington

International Nuclear Information System (INIS)

1993-05-01

This work plan and attached supporting project plans establish the operable unit setting and the objectives, procedures, tasks, and schedule for conducting the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) remedial investigation/feasibility study (RI/FS) for the 100-BC-2 operable unit in the 100 Area of the Hanford Site. The 100 Area is one of four areas at the Hanford Site that are on the US Environmental Protection Agency's (EPA) National Priorities List under CERCLA. The 100-BC-2 operable unit is one of two source operable units in the 100-B/C Area (Figure ES-1). Source operable units are those that contain facilities and unplanned release sites that are potential sources of hazardous substance contamination. The 100-BC-2 source operable unit contains waste sites that were formerly in the 100-BC-2, 100-BC-3, and 100-BC-4 operable units. Because of their size and geographic location, the waste sites from these two operable units were added to 100-BC-2. This allows for a more efficient and effective investigation of the remaining 100-B/C Reactor area waste sites. The investigative approach to waste sites associated with the 100-BC-2 operable unit are listed in Table ES-1. The waste sites fall into three general categories: high priority liquid waste disposal sites, low priority liquid waste disposal sites, and solid waste burial grounds. Several sites have been identified as candidates for conducting an IRM. Two sites have been identified as warranting additional limited field sampling. The two sites are the 116-C-2A pluto crib, and the 116-C-2C sand filter

In this paper, we investigate the scattering properties of the hyperbolic BC{sub n} Sutherland and the rational BC{sub n} Ruijsenaars–Schneider–van Diejen many-particle systems with three independent coupling constants. Utilizing the recently established action-angle duality between these classical integrable models, we construct their wave and scattering maps. In particular, we prove that for both particle systems the scattering map has a factorized form.

Full Text Available In this study, we aimed to determine lignified tissue in young stems of Struthanthus vulgaris Mart. by infrared microspectroscopy and histochemical methods as well as by fluorescence microscopy. Struthanthus vulgaris Mart. is a mistletoe species that belongs to the Loranthaceae family. A brief anatomical description was also carried out. The first procedure for analysis was to elaborate anatomical cross sections (20-30 µm from young stems before and after treatment with NaOH 1%. This procedure was applied to release possible low molecular mass phenolic compounds. Safranin-astra blue was used to distinguish anatomical tissues while Wiesner test enabled verification of lignified pericyclic fibers. Infrared microspectroscopy analysis confirmed the presence of lignin in this region according to the following spectral signals: 1600 (shoulder, 1511, 1453, 1338 and 1244 cm-1. Analyses of the cross section of young stems under fluorescence microscopy before and after treatment with NaOH 1% allowed us to confirm the presence of low mass phenolic compounds in the region of pericyclic fibers.

Natural, products were studied to combat reproductive alterations of lead. The current work aimed to disclose the efficacy of Chlorella vulgaris and Zingiber officinale to alleviate lead acetate induced toxicity. Sixty adult male Wistar rats were distributed into four groups. Group 1 was considered control, group 2 received 200 mg/l PbAc water, group 3 received 50 mg/kg/rat of C. vulgaris extract and 200 mg/l PbAc water, and group 4 received 100 mg/kg/rat of Z. officinale and 200 mg/l PbAc water for 90 days. Testis samples were subjected to ultrastructural examination. It was observed that PbAc caused degenerative alterations in the spermatogenic series in many tubules, with a loss of germ cells and vacuoles inside the cytoplasm and between the germ cells. Mitochondria exhibited ballooning, with lost cristae and widening of the interstitial tissue, while nuclear envelopes of primary spermatocytes were broken up, and axonemes of the mid-pieces of the sperms were distorted. With the treatment with C. vulgaris or Z. officinale, there were noticeable improvements in these modifications. It was concluded that both C. vulgaris and Z. officinale represent convincing medicinal components that may be used to ameliorate testicular toxicity in those exposed to lead in daily life with superior potentials revealed by C. vulgaris due to its chelating action.

We have explored interfacial interactions between a Mo–C terminated Mo 2 BC(040) surface and an Al cluster using ab initio molecular dynamics. The Al cluster is disrupted and wets the Mo 2 BC(040) surface. This can be understood based on the electronic structure. Across the Al–MoC interface C s–Al s hybridized states are formed. These bonds are stronger than the Al–Al intra-cluster bonds. Hence, the onset of Al adhesion is caused by bond formation across the Al–MoC interface. - Highlights: • Interfacial interactions between Mo 2 BC and an Al cluster were explored. • Al forms bonds to C constituting the onset of Al adhesion on Mo 2 BC. • These data are relevant for other carbide coatings
Mound No. 24 of the Alebastrovo I Burial Ground and the Problem of Succession Among the Early Nomadic Cultures of the Southern Urals in the 6th – 4th and 3rd – 1st Centuries BC

Full Text Available The article focuses on one of the burial mounds – Alebastrovo I, which is situated in the middle reaches of the Ural river. The analysis of the burial rite and grave goods reveals the combination of features peculiar of the culture of early nomads from the 6th to the 4th centuries BC and later features typical for the 3rd – 1st centuries BC. The collective nature of the burial in a large square pit (burial no. 2 relates to early features. Such burials are typical for the 5th and 4th centuries BC. But a dagger with a direct crosshair and a crescent-shaped pommel found in the burial belongs to the 3rd – 1st centuries BC. Findings of a mirror, a spoon and a whorl also deserve special attention. On formal grounds a mirror belongs to the type “Skripkin 1.6” – with a flat disk without roll and stick in the form of a triangular stem. They appeared in Sauromatian time, but were not widespread. Most of these mirrors refer to the turn of the eras – the first centuries AD. However, in our view the mirror from Alebastrovo I has the greatest similarity with the mirror disks of the so-called “musical” mirrors, which date back to the 2nd half of the 4th century BC. The bone spoon belongs to the type I, peculiar of the Sauromatian-time things of the 6th – 4th centuries BC. However, the pattern is similar to that on the handle of the bone products of later time – the 3rd – 2nd centuries BC. Clay whorl has a pattern in the form of 4 sectors, decorated with grooves and pits. Analogies are available on this ornament spindles from the 3rd – 2nd centuries BC of the Kara-Abyz culture in the Southern Urals. According to the set of attributes, this burial mound dated to the second half of the 3rd - 2nd centuries BC. The finds from this burial mound confirm the conclusion of the first explorer B. F. Zhelezchikov about continuity of the development of the early nomadic culture of this region in the 6th – 3rd centuries BC.

RNA sequencing takes advantage of the Next Generation Sequencing (NGS) technologies for analyzing RNA transcript counts with an excellent accuracy. Trying to interpret this huge amount of data in biological information is still a key issue, reason for which the creation of web-resources useful for their analysis is highly desiderable. Starting from a previous work, Transcriptator, we present the Atlas of Hydra's vulgaris, an extensible web tool in which its complete transcriptome is annotated. In order to provide to the users an advantageous resource that include the whole functional annotated transcriptome of Hydra vulgaris water polyp, we implemented the Atlas web-tool contains 31.988 accesible and downloadable transcripts of this non-reference model organism. Atlas, as a freely available resource, can be considered a valuable tool to rapidly retrieve functional annotation for transcripts differentially expressed in Hydra vulgaris exposed to the distinct experimental treatments.

A cylindrical 5.1 cmx5.1 cm scintillator cell filled with the KamLAND liquid scintillator has been exposed to monoenergetic neutron beams produced via the 2 H(d,n) 3 He reaction to measure the proton light-response function for energies up to 10 MeV. Using Birks' recipe, the α-particle light-response function was derived from these data. The same method was applied to the BC-501A and BC-517H liquid scintillators to check on the systematic accuracy of the present data. The proton and α-particle light-response functions are needed to correct the KamLAND antineutrino prompt energy spectrum for background effects caused by the reaction 13 C(α,n) 16 O. Especially, the geo-antineutrino energy regime measured in the KamLAND experiment is contaminated by background events from this reaction.

This document presents technical information on groundwater contamination in the 100-BC-5, 100-KR-4, 100-HR-3, and 100-FR-3 Operable Units on the Hanford Site in Richland, Washington. These operable units are defined for groundwater that underlies the retired plutonium production reactors and their associated support facilities. This technical information supports conceptual site models (CSM) for each operable unit. The goal in maintaining a CSM is to ensure that a reasonable understanding of contamination issues in each groundwater operable unit is available for selecting a final remediation alternative and for developing a record of decision. CSMs are developed for hazardous waste sites to help evaluate potential risks to human health and the environment from exposure to contamination
Electric energy supply and non-utility generation: A comparative analysis of B.C. and Wisconsin

The pricing policies and buyback rates (those concerned with purchase of non-utility generation, NUG) of British Columbia (BC) Hydro are examined along with their effectiveness in encouraging the efficient use and development of power. Specifically, the levels of self-generation within BC's pulp mills are examined as well as mill manager attitudes to increasing energy production. BC Hydro's encouragement of self-generation is determined by examining the ratio of the industrial rate for pulp mills to the utility's long-run marginal cost of power. BC Hydro's buyback policies are also examined to determine the level of encouragement they provide for increased self-generation. Comparisons are made with similar data, wherever possible, from utilities and pulp mills in Wisconsin. The comparison reveals similarities with respect to pulp mills' attitudes toward increasing self-generation capacity. A significant difference is noted in terms of the amount of pulp mill self-generation: Wisconsin mills generate substantially more of their own energy requirements than BC mills. Wisconsin utilities provided greater markup through their industrial rates, and also provided the greater encouragement for increased self-generation through their buyback policies. BC Hydro is the only utility that offered a load displacement policy, however. In summary, the policies and regulations of both BC and Wisconsin utilities have the potential to encourage greater industrial self-sufficiency and increased levels of self-generated power. Existing levels of encouragement are not determined solely by economic considerations but also reflect utility planning objectives. 97 refs., 3 figs., 20 tabs

Acne vulgaris is an extremely common condition affecting the pilosebaceous unit of the skin and characterized by presence of comedones, papules, pustules, nodules, cysts, which might result in permanent scars. Acne vulgaris commonly involve adolescents and young age groups. Active acne vulgaris is usually associated with several complications like hyper or hypopigmentation, scar formation and skin disfigurement. Previous studies have targeted the efficiency and safety of local and systemic agents in the treatment of active acne vulgaris. Superficial chemical peeling is a skin-wounding procedure which might cause some potentially undesirable adverse events. This study was conducted to review the efficacy and safety of superficial chemical peeling in the treatment of active acne vulgaris. It is a structured review of an earlier seven articles meeting the inclusion and exclusion criteria. The clinical assessments were based on pretreatment and post-treatment comparisons and the role of superficial chemical peeling in reduction of papules, pustules and comedones in active acne vulgaris. This study showed that almost all patients tolerated well the chemical peeling procedures despite a mild discomfort, burning, irritation and erythema have been reported; also the incidence of major adverse events was very low and easily manageable. In conclusion, chemical peeling with glycolic acid is a well-tolerated and safe treatment modality in active acne vulgaris while salicylic acid peels is a more convenient for treatment of darker skin patients and it showed significant and earlier improvement than glycolic acid.

This study is aiming at characterizing antifungal substances from the methanol extract of Prunella vulgaris and at investigating those substances' antifungal and antioomycete activities against various plant pathogens. Two polyacetylenic acids were isolated from P. vulgaris as active principles and identified as octadeca-9,11,13-triynoic acid and trans-octadec-13-ene-9,11-diynoic acid. These two compounds inhibited the growth of Magnaporthe oryzae, Rhizoctonia solani, Phytophthora infestans, Sclerotinia sclerotiorum, Fusarium oxysporum f. sp. raphani, and Phytophthora capsici. In addition, these two compounds and the wettable powder-type formulation of an n-hexane fraction of P. vulgaris significantly suppressed the development of rice blast, tomato late blight, wheat leaf rust, and red pepper anthracnose. These data show that the extract of P. vulgaris and two polyacetylenic acids possess antifungal and antioomycete activities against a broad spectrum of tested plant pathogens. This is the first report on the occurrence of octadeca-9,11,13-triynoic acid and trans-octadec-13-ene-9,11-diynoic acid in P. vulgaris and their efficacy against plant diseases. The crude extract containing the two polyacetylenic acids can be used as a natural fungicide for the control of various plant diseases. © 2010 The Authors. © 2010 The Society for Applied Microbiology.
Changes in weed infestations on plantations of sugar beet (Beta vulgaris L. subsp. vulgaris cultivated on black soil near Wrocław in 1989–1995 and 2006–2012

Full Text Available Field studies were carried out in 1989–1995 and 2006–2012 on plantations of sugar beet (Beta vulgaris L. subsp. vulgaris. During this period, 542 phytosociological relevés were made using the Braun-Blanquet method. In total, 46 weed species were found. In 1989–1995, the occurrence of 36 segetal species was reported. The highest cover indices were determined for Chenopodium album and Amaranthus retroflexus. Galium aparine, Echinochloa crus-galli, and Elymus repens were the dominant species, as well. Analysis of the frequency of occurrence revealed one constant species (Chenopodium album, two frequent species (Amaranthus retroflexus and Galium aparine, and two medium-frequent species (Echinochloa crus-galli and Matricaria maritima ssp. inodora. In 2006–2012, the occurrence of 40 weed species on the sugar beet plantations was recorded. The plantations were clearly dominated by Chenopodium album, accompanied by Polygonum persicaria and Polygonum lapathifolium ssp. lapathifolium. Other dominant species comprised Setaria viridis, Galinsoga parviflora, Brassica napus ssp. napus, and Fallopia convolvulus. The Chenopodium album was a constant component of the sugar beet plantations. In turn, no frequent species were observed and six medium-frequent species were found (Setaria viridis, Galinsoga parviflora, Brassica napus ssp. napus, Echinochloa crus-galli, Amaranthus retroflexus, and Capsella bursa-pastoris. Noteworthy, the presence of previously unreported species, e.g., Abutilon theophrasti, Hyoscyamus niger, or Artemisia vulgaris, was revealed. These species are rare components in sugar beet crops. A reverse phenomenon, i.e., the disappearance of some species such as Euphorbia helioscopia, Malva neglecta, Rumex acetosella, Sinapis arvensis, or Sisymbrium officinale, was also observed.

The effects of different concentrations of bisphenol A (BPA) on Chlorella vulgaris and removal capacity of BPA by Chlorella vulgaris were investigated. Results showed that a low concentration (0-20 mg x L(-1)) of BPA promoted the growth of Chlorella vulgaris, whereas a relative high concentration (20-50 mg x L(-1)) of BPA inhibited the growth of Chlorella vulgaris, and the inhibition effect was positively correlated with the concentration of BPA. Likewise, a high dose of initial BPA (> 20 mg x L(-1)) led to a decline in the content of chlorephyll a. Chlorella vulgaris had BPA removal capacity when initial BPA concentration ranged from 2 mg x L(-1) to 50 mg x L(-1). There was positive correlation between the removal rate of BPA per cell and initial BPA concentration. The removal rate of BPA was the highest when initial BPA was 50 mg x L(-1), which appeared between lag phase and logarithmic phase.

Olfactory organ of Octopus vulgaris: morphology, plasticity, turnover and sensory characterization

Full Text Available The cephalopod olfactory organ was described for the first time in 1844 by von Kölliker, who was attracted to the pair of small pits of ciliated cells on each side of the head, below the eyes close to the mantle edge, in both octopuses and squids. Several functional studies have been conducted on decapods but very little is known about octopods. The morphology of the octopus olfactory system has been studied, but only to a limited extent on post-hatching specimens, and the only paper on adult octopus gives a minimal description of the olfactory organ. Here, we describe the detailed morphology of young male and female Octopus vulgaris olfactory epithelium, and using a combination of classical morphology and 3D reconstruction techniques, we propose a new classification for O. vulgaris olfactory sensory neurons. Furthermore, using specific markers such as olfactory marker protein (OMP and proliferating cell nuclear antigen (PCNA we have been able to identify and differentially localize both mature olfactory sensory neurons and olfactory sensory neurons involved in epithelium turnover. Taken together, our data suggest that the O. vulgaris olfactory organ is extremely plastic, capable of changing its shape and also proliferating its cells in older specimens.

In this study, the flocculation process of Chlorella vulgaris and Rhodotorula glutinis induced by inorganic salts modified montmorillonoid was conducted. The maximum flocculation efficiency (FE) of 98.50% for C. vulgaris and 11.83% for R. glutinis were obtained with 4g/L and 5g/L flocculant within the dosage scope of 1-5g/L. The difference of FE was then thermodynamically explained by the extended DLVO theory and the FE of R. glutinis was mechanically enhanced to 90.66% with 0.06g/L cationic polyacrylamide (CPAM) at an optimum pH of 9. After that, aimed to utilize the remainder flocculant capacity, C. vulgaris culture was added to the aggregation of R. glutinis. Fortunately, the coagulation of R. glutinis and C. Vulgaris was achieved with 0.05g/L CPAM and 5g/L flocculant at pH 9 and the FE reached 90.15% and 91.24%, respectively. Copyright © 2016 Elsevier Ltd. All rights reserved.

Discharge of dye-containing wastewater by the textile industry can adversely affect aquatic ecosystems and human health. Bioremoval is an alternative to industrial processes for detoxifying water contaminated with dyes. In this work, active and inactive biomass of the microalga Chlorella vulgaris was assayed for the ability to remove Congo Red (CR) dye from aqueous solutions. Through biosorption and biodegradation processes, Chlorella vulgaris was able to remove 83 and 58 % of dye at concentrations of 5 and 25 mg L(-1), respectively. The maximum adsorption capacity at equilibrium was 200 mg g(-1). The Langmuir model best described the experimental equilibrium data. The acute toxicity test (48 h) with two species of cladocerans indicated that the toxicity of the dye in the effluent was significantly decreased compared to the initial concentrations in the influent. Daphnia magna was the species less sensitive to dye (EC50 = 17.0 mg L(-1)), followed by Ceriodaphnia dubia (EC50 = 3.32 mg L(-1)). These results show that Chlorella vulgaris significantly reduced the dye concentration and toxicity. Therefore, this method may be a viable option for the treatment of this type of effluent.

Variation of geomagnetic field changes in the Iberian Peninsula between prior to roman times remain very poorly constrained. Here we report results from the archeomagnetic study carried out on four set of ceramics and one combustion structure recovered in two pre-roman (celtiberic) archeological sites in central Spain. Rock magnetic experiments indicate the ChRM is carried by magnetite. Archaeointensity determinations were carried out by using the classical Thellier-Thellier experiment including tests and corrections for magnetic anisotropy and magnetic cooling rate dependency. Well heated specimens (red ceramic fragments and well heated samples from the kiln) show one single well defined component of magnetisation going through the origin and a linear arai plot providing successful archaeointensity determinations. The effect of anisotropy of the termoremanent magnetization (ATRM) on paleointensity analysis was specially investigated obtaining very high ATRM corrections on fine pottery specimens. With differences between the uncorrected and ATRM corrected paleointensity values that reached up to 80-100%. Mean intensity values obtained from three selected groups were 61.1 ±5.9μT; 57.6±3.3 and 56.4± 4.7μT which allows delineate the evolution of the paleofield intensity in central Iberia during the III-I centuries BC. The new archaeointensity data disagrees with previous results from Iberian ceramics which were not corrected by the ATRM effect. But they are in agreement with the most recent French paleointensity curve and latest European intensity model. Both based on a selection of high quality paleointensity data. This result reinforces the idea that the puzzling scatter often observed in the global paleointensity database is likely due to differences in the laboratory protocol. Further data from well contrasted laboratory protocols are still necessary to delineate confidently the evolution of the geomagnetic paleofield during the first millennium BC.

2010-01-01

The uranium removal efficiencies of rhizofiltration in the remediation of groundwater were investigated in lab-scale experiments. Sunflower (Helianthus annuus L.) and bean (Phaseolus vulgaris L. var. vulgaris) were cultivated and an artificially uranium contaminated solution and three genuine groundwater samples were used in the experiments. More than 80% of the initial uranium in solution and genuine groundwater, respectively, was removed within 24 h by using sunflower and the residual uranium concentration of the treated water was lower than 30 μg/L (USEPA drinking water limit). For bean, the uranium removal efficiency of the rhizofiltration was roughly 60-80%. The maximum uranium removal via rhizofiltration for the two plant cultivars occurred at pH 3-5 of solution and their uranium removal efficiencies exceeded 90%. The lab-scale continuous rhizofiltration clean-up system delivered over 99% uranium removal efficiency, and the results of SEM and EDS analyses indicated that most uranium accumulated in the roots of plants. The present results suggested that the uranium removal capacity of two plants evaluated in the clean-up system was about 25 mg/kg of wet plant mass. Notably, the removal capacity of the root parts only was more than 500 mg/kg.

Acne vulgaris is the most common cutaneous disorder affecting adolescents and young adults. Small, noninflamed acne lesions may not be more than a slight nuisance, but, in individuals with more severe inflammatory disease, pain, social embarrassment, and both physical and psychological scarring can be life altering. Despite its high prevalence, no previous community-based studies have been conducted in Arar, northern border of Kingdom of Saudi Arabia, addressing this issue. The aim of this study was to estimate the prevalence of acne vulgaris, to describe the sociodemographic characteristics of cases, and to determine the aggravating factors and the psychological impact of acne vulgaris in a representative sample of secondary school male students in Arar city, Kingdom of Saudi Arabia. This was a cross-sectional study. A multistage systematic random sampling technique was followed. A total of 400 male students during the academic year 2015-2016 were included in the study. Data were collected by means of personal interview and filling-in a questionnaire. The overall prevalence of acne vulgaris was 53.5%. The mean age of onset was 15.0±1.2 years. Positive family history of acne vulgaris was found in 46.7% of cases. The skin was greasy in 61.7% of cases. Acne site was the face in 67.3%, the back in 4.7%, and both in 28% of the cases. More than half (54.2%) of the cases had first-degree acne. Students mentioned several factors affecting the appearance of acne; 59.8% of cases reported a relation of increased acne appearance with the cleanliness of the skin, 35.5% reported relation with consumption of fatty meals, 24.2% with eating chocolate, 23.3% with consumption of spicy food, 12.1% with excess intake of cola drinks, 31.8% with heavy smoking, and 60.7% reported increased acne appearance in summer months. Acne was highly prevalent among secondary school male students in Arar city, Kingdom of Saudi Arabia. Several risk factors increased the appearance of acne, including

The aims of this study were to quantify the contributions of activities or microenvironments (MEs) to daily total exposure to and potential dose of black carbon (BC). Daily BC exposures (24-h) were monitored using a micro-aethalometer micoAeth AE51 with forty school-aged children living in an urban area in Korea from August 2015 to January 2016. The children's time-activity patterns and the MEs they visited were investigated by means of a time-activity diary (TAD) and follow-up interviews with the children and their parents. Potential inhaled dose was estimated by multiplying the airborne BC concentrations (μg/m3) we monitored for the time the children spent in a particular ME by the inhalation rate (IR, m3/h) for the time-activity performed. The contribution of activities and MEs to overall daily exposure to and potential dose of BC was quantified. Overall mean daily potential dose was equal to 24.1 ± 10.6 μg/day (range: 6.6-46.3 μg/day). The largest contribution to BC exposure and potential dose (51.9% and 41.7% respectively) occurred in the home thanks to the large amount of time spent there. Transportation was where children received the most intense exposure to (14.8%) and potential dose (20.2%) of BC, while it accounted for 7.6% of daily time. School on weekdays during the semester was responsible for 20.3% of exposure and 22.5% of potential dose. Contribution to BC exposure and potential dose was altered by several time-activity parameters, such as type of day (weekdays vs. weekends; school days vs. holidays), season, and gender. Traveling by motor vehicle and subway showed more elevated exposure or potential dose intensity on weekdays or school days, probably influenced by the increased surrounding traffic volumes on these days compared to on weekends or holidays. This study may be used to prioritize targets for minimizing children's exposure to BC and to indicate outcomes of BC control strategies.
Effects of Planting of Calluna Vulgaris for Stable Snow Accumulation in Winter

Recent year climate of the winter season is changing and the period of snow accumulation is reduced compared with before. It affects the management of the ski resort. Snowfall had occurred in December 2016, but the snow accumulated after January 2017 at the ski resort located in the Pacific Ocean side of the Northeast region of Japan. This situation is thought to be originated from two reasons, one is snow thawing, another is to be blown away by the strong monsoon wind. We are considering utilizing planting to stabilize snow accumulation. Currently building rock gardens with shrubs, mainly Calluna Vulgaris in the ski resort for attracting customers in the summer. These are difficult to raise in the lowlands of Japan because they are too hot, but because of their good growth in relatively low-temperature highlands, it is rare for local residents to appreciate the value of these. In addition, it is excellent in low temperature resistance, and it will not die even under the snow. We investigated the pressure resistance performance due to snowfall and the appropriateness of growth under the weather conditions of the area. Regarding Calluna Vulgaris, Firefly, the plants were not damaged even under snow more than 1 m. In addition, three years have passed since planting, relatively good growth is shown, and the stock has been growing every year. Based on these results, we plan to stabilize the snow accumulation by carrying out planting of Calluna vulgaris inside the slope. The growth of the Calluna species is gentle and the tree height grows only about 50 cm even if 15 years have passed since planting. Therefore, it is considered that the plant body is hard to put out their head on the snow surface during the ski season. Next season will monitor the snow accumulation around the planting area through the snow season.

A cylindrical 5.1 cmx5.1 cm scintillator cell filled with the KamLAND liquid scintillator has been exposed to monoenergetic neutron beams produced via the {sup 2}H(d,n){sup 3}He reaction to measure the proton light-response function for energies up to 10 MeV. Using Birks' recipe, the {alpha}-particle light-response function was derived from these data. The same method was applied to the BC-501A and BC-517H liquid scintillators to check on the systematic accuracy of the present data. The proton and {alpha}-particle light-response functions are needed to correct the KamLAND antineutrino prompt energy spectrum for background effects caused by the reaction {sup 13}C({alpha},n){sup 16}O. Especially, the geo-antineutrino energy regime measured in the KamLAND experiment is contaminated by background events from this reaction.

Highlights: • Al adheres to many surfaces. • Solid–solid interactions challenging for real (oxidized) surfaces. • Dissociative O{sub 2} adsorption on Mo{sub 2}BC(0 4 0). • Al nonamer is disrupted on oxidized Mo{sub 2}BC(0 4 0). • Adhesion of a residual Al on the native oxide. - Abstract: A Mo{sub 2}BC(0 4 0) surface was exposed to O{sub 2}. The gas interaction was investigated using ab initio molecular dynamics and X-ray photoelectron spectroscopy (XPS) of air exposed surfaces. The calculations suggest that the most dominating physical mechanism is dissociative O{sub 2} adsorption whereby Mo−O, O−Mo−O and Mo{sub 2}−C−O bond formation is observed. To validate these results, Mo{sub 2}BC thin films were synthesized utilizing high power pulsed magnetron sputtering and air exposed surfaces were probed by XPS. MoO{sub 2} and MoO{sub 3} bond formation is observed and is consistent with here obtained ab initio data. Additionally, the interfacial interactions of O{sub 2} exposed Mo{sub 2}BC(0 4 0) surface with an Al nonamer is studied with ab initio molecular dynamics to describe on the atomic scale the interaction between this surface and Al to mimic the interface present during cold forming processes of Al based alloys. The Al nonamer was disrupted and Al forms chemical bonds with oxygen contained in the O{sub 2} exposed Mo{sub 2}BC(0 4 0) surface. Based on the comparison of here calculated adsorption energy with literature data, Al−Al bonds are shown to be significantly weaker than the Al−O bonds formed across the interface. Hence, Al−Al bond rupture is expected for a mechanically loaded interface. Therefore the adhesion of a residual Al on the native oxide layer is predicted. This is consistent with experimental observations. The data presented here may also be relevant for other oxygen containing surfaces in a contact with Al or Al based alloys for example during forming operations.

We investigated the occurrence of two plant endornaviruses, Phaseolus vulgaris endornavirus 1 and Phaseolus vulgaris endornavirus 2, in breeding lines, cultivars, landraces, and wild genotypes of common bean (Phaseolus vulgaris) collected from the two centers of common bean domestication: Mesoamerica and the Andes. The two endornaviruses were detected in many genotypes of Mesoamerican origin but rarely in genotypes of Andean origin. The results suggest that these two endornaviruses were introduced into the Mesoamerican modern genotypes during common bean domestication and provide more evidence for the existence of two divergent gene pools of common bean.
BC Hydro's transmission business : transition to a competitive marketplace

Progress made by BC Hydro to facilitate the use of the transmission system for wholesale electricity transactions, including the separation of the system operation function from generation and merchant functions, was discussed. BC Hydro, Canada's third largest electric utility, was the first Canadian utility to offer open access to its transmission system for wholesale transactions. The utility has an installed generating capacity of about 10.8 gigawatts, 90 per cent of which is hydroelectric. The remainder is thermal, gas turbine and stationary and mobile diesel generation. The key element in establishing wholesale transmission transactions was the FERC-mandated open access same-time information system (OASIS) on which BC Hydro posts available transmission capacity, planned outages and pricing. The system operates on BC Hydro's internet node and interfaces to a Transmission Scheduling System (TSS). The TSS was developed in-house to handle the increased complexity of scheduling multiple energy and capacity transactions for users of the transmission system. Operation of the system and the challenge to constantly improve it were discussed

Full Text Available The article deals with the new attribution of the materials from barrow 20, excavated in 1975 near Semenovka village on the right bank of the Dniester liman, Belgorod-Dnesterovsky district, Odessa region, Ukraine. The only burial of this barrow was still considered as the monument of Babino culture (aka Multi-Cordoned Ware culture of the first quarter of the 2nd millennium BC. The ceramic and metal artifacts found under the barrow were considered during the study of the material culture of the Scythians of the last third of the 1st millennium BC. The thorough analysis of the stratigraphy, planigraphy, funeral rite and artifacts showed that barrow 20 near Semenovka village was built instantaneously, and in fact it is Scythian. A cenotaph was the main complex of the barrow. It came with not only the armament items (iron-socketed arrowheads, spearheads and sockets of spears, horse harness (bronze frontlet with axe-shaped blade and a hook, bronze ringed beads, iron bits and iron snaffle ring, iron round pendants, glass cup, remains of the funeral feast as a ceramic breakage (Rhodes, Sinop, Cos, Cnidus amphorae, two pottery jars and molded vessel, but also with the burial of a dependent person lying crouched on his left side, his head in the eastern sector, in the catacomb. Depth of the fixing of these findings corresponded to the level of the ancient horizon on which the two-sided mainland ejected from the burial construction. Based on the Rhodes amphora marked with the eponym Άγήσιππος of - manufacturer - Έπίγονος 1, the barrow dates back to the last third or last quarter of the 3rd century BC.

The accumulation (internal and superficial distribution) of magnesium ions (Mg(2+)) by the green freshwater microalga Chlorella vulgaris (C. vulgaris) was investigated under autotrophic culture in a stirred photobioreactor. The concentrations of the three forms of Mg(2+) (dissolved, extracellular, and intracellular) were determined with atomic absorption spectroscopy during the course of C. vulgaris growth. The proportions of adsorbed (extracellular) and absorbed (intracellular) Mg(2+) were quantified. The concentration of the most important pigment in algal cells, chlorophyll a, increased over time in proportion to the increase in the biomass concentration, indicating a constant chlorophyll/biomass ratio during the linear growth phase. The mean-average rate of Mg(2+) uptake by C. vulgaris grown in a culture medium starting with 16 mg/l of Mg(2+) concentration was measured. A clear relationship between the biomass concentration and the proportion of the Mg(2+) removal from the medium was observed. Of the total Mg(2+) present in the culture medium, 18% was adsorbed on the cell wall and 51% was absorbed by the biomass by the end of the experiment (765 h). Overall, 69% of the initial Mg(2+) were found to be removed from the medium. This study supported the kinetic model based on a reversible first-order reaction for Mg(2+) bioaccumulation in C. vulgaris, which was consistent with the experimental data.

Variations of geomagnetic field in the Iberian Peninsula prior to roman times are poorly constrained. Here we report new archaeomagnetic results from four ceramic collections and two combustion structures recovered in two pre-roman (celtiberic) archaeological sites in central Spain. The studied materials have been dated by archaeological evidences and supported by five radiocarbon dates. Rock magnetic experiments indicate that the characteristic remanent manetization (ChRM) is carried by a low coercivity magnetic phase with Curie temperatures of 530-575 °C, most likely Ti-poor titanomagnetite/titanomaghemite. Archaeointensity determinations were carried out by using the classical Thellier-Thellier protocol including tests and corrections for magnetic anisotropy and cooling rate dependency. Two magnetic behaviours were depicted during the laboratory treatment. Black potsherds and poor heated samples from the kilns, presented two magnetization components, alterations or curved Arai plots and were therefore rejected. In contrast, well heated specimens (red ceramic fragments and well heated samples from the kilns) show one single well defined component of magnetization going through the origin and linear Arai plots providing successful archaeointensity determinations. The effect of anisotropy of the thermoremanent magnetization (ATRM) on paleointensity analysis was systematically investigated obtaining very high ATRM corrections on fine pottery specimens. In some cases, differences between the uncorrected and ATRM corrected paleointensity values reached up to 86 %. The mean intensity values obtained from three selected set of samples were 64.3 ± 5.8 μT; 56.8 ± 3.8 and 56.7 ± 4.6 μT (NUS2, CI2 and CIA, respectively), which contribute to better understand the evolution of the palaeofield intensity in central Iberia during the 3rd-1st centuries BC. The direction of the field at first century BC has also been determined from oriented samples from CIA kilns (D = 357

Chlorella vulgaris (C. vulgaris), a unicellular green microalga, has been widely used as a food supplement and reported to have antioxidant and anticancer properties. The current study was designed to assess the cytotoxic, apoptotic, and DNA-damaging effects of C. vulgaris growth factor (CGF), hot water C. vulgaris extracts, inlung tumor A549 and NCI-H460 cell lines. A549 cells, NCI-H460 cells, and normal human fibroblasts were treated with CGF at various concentrations (0-300 μg/ml) for 24 hr. The comet assay and γH2AX assay showed DNA damage in A549 and NCI-H460 cells upon CGF exposure. Evaluation of apoptosis by the TUNEL assay and DNA fragmentation analysis by agarose gel electrophoresis showed that CGF induced apoptosis in A549 and NCI-H460 cells. Chlorella vulgaris hot water extract induced apoptosis and DNA damage in human lung carcinoma cells. CGF can thus be considered a potential cytotoxic or genotoxic drug for treatment of lung carcinoma. Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.

Energy utility companies must balance production from limited sources with increasing demand from industrial, business, and residential consumers. The utility planning process requires a balanced, efficient, and effective distribution of energy from source to consumer. Therefore utility planners must consider the impact of weather on energy production and consumption. Hydro-electric companies should be particularly tuned to weather because their source of energy is water, and water supply depends on precipitation. BC Hydro operates as the largest hydro-electric company in western Canada, managing over 30 reservoirs within the province of British Columbia, and generating electricity for 1.6 million people. BC Hydro relies on weather forecasts of watershed precipitation and temperature to drive hydrologic reservoir inflow models and of urban temperatures to meet energy demand requirements. Operations and planning specialists in the company rely on current, value-added weather forecasts for extreme high-inflow events, daily reservoir operations planning, and long-term water resource management. Weather plays a dominant role for BC Hydro financial planners in terms of sensitive economic responses. For example, a two percent change in hydropower generation, due in large part to annual precipitation patterns, results in an annual net change of \\50 million in earnings. A five percent change in temperature produces a \\5 million change in yearly earnings. On a daily basis, significant precipitation events or temperature extremes involve potential profit/loss decisions in the tens of thousands of dollars worth of power generation. These factors are in addition to environmental and societal costs that must be considered equally as part of a triple bottom line reporting structure. BC Hydro water resource managers require improved meteorological information from recent advancements in numerical weather prediction. At BC Hydro, methods of providing meteorological forecast data

Bacterial cellulose (BC) is a polymer of glucose monomers, which has unique properties including high crystallinity and high strength. It has potential to be used in biomedical applications such as making artificial blood vessel, wound dressings, and in the paper making industry. Extensive study on BC aimed to improve BC production such as by using glycerol as a cheaper carbon source. BC was produced in shake flask culture using five different concentrations of glycerol (10, 20, 30, 40 and 50 g/ L). Using concentration of glycerol above 20 g/ L inhibited culture growth and BC production. Further experiments were performed in batch culture (3-L bioreactor) using 20 g/ L glycerol. It produced yield and productivity of 0.15 g/ g and 0.29 g/ L/ day BC, respectively. This is compared with the control medium, 50 g/ L glucose, which only gave yield and productivity of 0.05 g/ g and 0.23 g/ L/ day, respectively. Twenty g/ L of glycerol enhanced BC production by Gluconacetobacter xylinus DSM46604 in batch fermentation system. (author)

Candida albicans (C. albicans) and Proteus species are causative agents in a variety of opportunistic nosocomial infections, and their ability to form biofilms is known to be a virulence factor. In this study, the influence of co-cultivation with Proteus vulgaris (P. vulgaris) and Proteus mirabilis (P. mirabilis) on C. albicans biofilm formation and its underlying mechanisms were examined. XTT reduction assays were adopted to measure biofilm formation, and viable colony counts were performed to quantify yeast growth. Real-time reverse transcriptase polymerase chain reaction was used to evaluate the expression of yeast-specific genes (rhd1 and rbe1), filament formation inhibiting genes (tup1 and nrg1), and hyphae-related genes (als3, ece1, hwp1, and sap5). Candida biofilm formation was markedly inhibited by treatment with either living or heat-killed P. vulgaris and P. mirabilis. Proteus-cultured supernatant also inhibited Candida biofilm formation. Likewise, treatment with live P. vulgaris or P. mirabilis or with Proteus-cultured supernatant decreased expression of hyphae-related C. albicans genes, while the expression of yeast-specific genes and the filament formation inhibiting genes of C. albicans were increased. Heat-killed P. vulgaris and P. mirabilis treatment, however, did not affect the expression of C. albicans morphology-related genes. These results suggest that secretory products from P. vulgaris and P. mirabilis regulate the expression of genes related to morphologic changes in C. albicans such that transition from the yeast form to the hyphal form can be inhibited. © Copyright: Yonsei University College of Medicine 2017

Full Text Available Continuous black carbon (BC observations were conducted from 1999 through 2009 by an Aethalometer (AE10 and from 2006 through 2011 by a Multi-Angle Absorption Photometer (MAAP at Neumayer Station (NM under stringent contamination control. Considering the respective observation period, BC concentrations measured by the MAAP were somewhat higher (median ± standard deviation: 2.1 ± 2.0 ng m⁻³ compared to the AE10 results (1.6 ± 2.1 ng m⁻³. Neither for the AE10 nor for the MAAP data set a significant long-term trend could be detected. Consistently a pronounced seasonality was observed with both instruments showing a primary annual maximum between October and November and a minimum in April with a maximum/minimum ratio of 4.5/1.6 = 3.8 and 2.7/0.64 = 4.2 for the MAAP and AE10 data, respectively. Occasionally a secondary summer maximum in January/February was visible. With the aim to assess the impact of BC on optical properties of the aerosol at NM, we evaluated the BC data along with particle scattering coefficients measured by an integrating nephelometer. We found the mean single scattering albedo of ω₅₅₀ = 0.992 ± 0.0090 (median: 0.994 at a wavelength of 550 nm with a range of values from 0.95 to 1.0.

The research evaluating adipokines are very few in patients with acne vulgaris. The hypothesis that hyperinsulinemic and high glycemic index diet plays a role in the pathogenesis of acne is still controversial. In this study, we aimed to evaluate adipokines such as leptin (L), adiponectin (A), ghrelin and A levels, and A/L rates that indicate insulin resistance in nonobese patients with severe acne vulgaris. Thirty patients who are nonobese with moderate acne vulgaris, aged 18 to 25 years, and 15 age-sex compatible controls were included in our study. The acne lesions were assessed using the Global Acne Grading Scale (GAGS). All participants were evaluated for the parameters that may affect the metabolism of serum L, A, and ghrelin levels in blood, and their body mass index were calculated. The significance level was determined as p ≤ 0.05. Of the 30 patients, 17 were women and 13 were men. The mean age was 20.60 years and the mean duration of the disease were 2.8 years. All of patients had moderate acne vulgaris (GAGS 19-30). Of the 15 controls, 11 were women and 4 were men. The mean age was 21.20 years. There were not a statistically significant difference in L, ghrelin, A levels, and A/L ratio between the two groups. Adipokines may have a role in the pathogenesis of acne vulgaris. L, A, ghrelin, and insulin resistance may not participate in the responsible mechanisms in nonobese patients with moderate acne vulgaris. © The Author(s) 2016.

Since 1978, 20 surgical implantations of either Strongylus vulgaris or Strongylus edentatus have been performed in our laboratory for the purpose of obtaining single species cultures of these parasites. Following surgical implantation peak EPG values of 13-327 (S. vulgaris) and 363-1284 (S. edentatus) generally occurred during the first 3 weeks post-implantation. Duration of infections was as long as 5 years. Successful outcome of such surgeries appears to be related to the total number of parasites used (> or = 38) and the ratio of female to male worms implanted (1:1 or 2:1).

Full Text Available Background and Objective: Chlorella vulgaris is a multi-cellular edible algal species with abundant proteins. Extraction of high value protein fractions for pharmaceutical and nutritional applications can significantly increase the commercial value of microalga biomasses. There is no known report on the anticancer peptides derived from the Chlorella vulgaris abundant protein.Materials and Methods: This study examined the antimicrobial and anticancer effects of peptides from a hydrolyzed Chlorella vulgaris protein with 62 kDa molecular weight. Protein hydrolysis was done by pepsin as a gastrointestinal protease, and was monitored through protein content measurement, sodium dodecyl sulfate polyacrylamide gel electrophoresis, and high performance liquidchromatography measurements. Inhibitory effect of the produced peptides on Escherichia coli cells and breast cancer cell lines was assayed.Results and Conclusion: Hydrolyzed peptides induced a decrease of about 34.1% in the growth of Escherichia coli, and the peptides of 3 to 5 kDa molecular weight had strong impact on the viability of breast cancer cells with IC50 value of 50 μg μl-1. The peptide fractions demonstrating antimicrobial and anti-cancer activities have the potential for use as functional food ingredients for health benefits. These results demonstrate that inexpensive algae proteinscould be a new alternative to produce anticancer peptides.Conflict of interest: The authors declare that there is no conflict of interest.

The effect of pulsed electric field (PEF) treatments of different intensities on the electroporation of the cytoplasmatic membrane of Chlorella vulgaris, and on the extraction of carotenoids and chlorophylls were investigated. Staining the cells with propidium iodide before and after the PEF treatment revealed the existence of reversible and irreversible electroporation. Application of PEF treatments in the range of 20-25 kV cm(-1) caused most of the population of C. vulgaris to be irreversibly electroporated even at short treatment times (5 pulses of 3 µs). However, at lower electric field strengths (10 kV cm(-1)), cells that were reversibly electroporated were observed even after 50 pulses of 3 µs. The electroporation of C. vulgaris cells by PEF higher than 15 kV cm(-1) and duration is higher than 15 µs increased significantly the extraction yield of intracellular components of C. vulgaris. The application of a 20 kV cm(-1) for 75 μs increased the extraction yield just after the PEF treatment of the carotenoids, and chlorophylls a and b 0.5, 0.7, and 0.8 times, respectively. However, further increments in electric field strength and treatment time did not cause significant increments in the extraction yield. The extraction of carotenoids from PEF-treated C. vulgaris cells after 1 h of the application of the treatment significantly increased the extraction yield in comparison to the yield obtained from the cells extracted just after the PEF treatment. After PEF treatment at 20 kV cm(-1) for 75 µs, extraction yield for carotenoids, and chlorophylls a and b increased 1.2, 1.6, and 2.1 times, respectively. A high correlation was observed between irreversible electroporation and percentage of yield increase when the extraction was conducted after 1 h of the application of PEF treatment (R: 0.93), but not when the extraction was conducted just after PEF treatment (R: 0.67).
A new era of prosperity through power : maintaining BC's competitive advantage

Energy Technology Data Exchange (ETDEWEB)

Potts, D. [BC Council of Forest Industries, Vancouver, BC (Canada)

2001-08-17

The availability of abundant low cost electric power has been a driving force behind British Columbia's economic growth. BC's low cost power resources can create a natural competitive economic advantage for the province. Electricity, as a publicly owned resource can offer many competitive advantages for business in British Columbia, if managed correctly. However, it was noted that meaningful economic advantages can only be realized if the existing power resources in the province are operated efficiently and priced at or close to cost. In the 1980s, the Joint Industry Electricity Steering Committee (JIESC) was formed following the regulation of BC Hydro by BC Utilities Commission. It became clear that maintaining low rates for electricity was a public issue that needed input from other governmental forums if JIESC was to be successful. The major sectors represented by JIESC include pulp and paper, mining, and electrochemicals. This paper listed each member company. In order to turn BC's economy around and re-establish the province as a leading economy in Canada, the following recommendations have been proposed for the short term: (1) maintain an ample supply of low cost power for the future, (2) remove the provincial sales tax on the purchase of electric power used for manufacturing and processing, (3) extend the current rate freeze, (4) initiate a long-term resource acquisition and transmission expansion strategy to assure the availability of ample supplies of low cost power. Recommendations for the long term include: (1) maintain regulated cost based rates, (2) develop ample low cost power, (3) utilize downstream benefits, (4) provide a role for the private sector, (5) maintain adequate transmission facilities, (6) reduce government revenues, and (7) instill customer driven management. 3 figs.

Mayhead, Elyssia; Llewellyn, Carole A.; Fuentes-Grünewald, Claudio

2018-01-01

The nutrient removal efficiency of Chlorella vulgaris cultivated in domestic wastewater was investigated, along with the potential to use membrane filtration as a pre-treatment tool during the wastewater treatment process. Chlorella vulgaris was batch cultivated for 12 days in a bubble column system with two different wastewater treatments. Maximum uptake of 94.18% ammonium (NH4-N) and 97.69% ortho-phosphate (PO4-P) occurred in 0.2 μm membrane filtered primary wastewater. Membrane filtration enhanced the nutrient uptake performance of C. vulgaris by removing bacteria, protozoa, colloidal particles and suspended solids, thereby improving light availability for photosynthesis. The results of this study suggest that growing C. vulgaris in nutrient rich membrane filtered wastewater provides an option for domestic wastewater treatment to improve the quality of the final effluent.

Full Text Available Objective: To determine the presence of bioactive molecules and to check their antimicrobial activity from green algae Chlorella vulgaris (AS-3 (C. vulgaris isolated from Unkal Lake in Dharwad District, Karnataka, India. Methods: Based on the polarity, benzene, chloroform, ethyl acetate, ethanol, hexane, methanol, petroleum ether and distilled water were the solvents used for the preparation of algal extracts using Soxhlet apparatus, which were further subjected to phytochemical analysis and screening of antimicrobial activity. Human pathogens such as Staphylococcus aureus, Corynebacterium, Bacillus subtilis, Streptococcus, Escherichia coli, Salmonella Paratyphi B, Klebsiella pneumoniae, Aerobacter aerogenes, Candida albicans and Aspergillus niger were used for antimicrobial assay. Standard methods were followed for qualitative estimation of phytochemicals. Results: Phytochemical determination of bioactive molecules showed the presence of alkaloids, flavonoids, glycosides, carotenoids, phenols, lignins, saponins, sterols, tannins, reducing sugars, volatile oil, fats, amino acids and carbohydrates. In vitro analysis of organic solvent extracts of C. vulgaris, a green microalgae, showed an activity by suppressing the proliferation of bacterial, fungal and human pathogens. Four extracts (chloroform, ethyl acetate, hexane and methanol showed effective inhibitory activity against the tested pathogens. Depending on the percentage of bioactive molecules present in each of the organic extracts, different extracts showed different inhibition zone diameters against the pathogens. Among the eight organic extracts used for the study, excellent inhibitory effects were shown by chloroform and methanol extracts. Conclusions: The present study indicates that green algae C. vulgaris is rich in natural compounds which are highly important in pharmacology and nutraceuticals. Although the presence of bioactive molecules is very less in the algae, excellent effect

Sodium pentaborate pentahydrate (SPP) is a rare mineral. In this study, SPP was synthesized from boric acid and borax through low-temperature crystallization, and its effects on the growth of the alga, Chlorella vulgaris (C. vulgaris) were assessed. The newly synthesized SPP was characterized by chemical analysis, X-ray diffraction, Fourier-transform infrared spectroscopy, Raman spectroscopy, thermogravimetric analysis, and differential thermal analysis. The changes in C. vulgaris growth, chlorophyll content, and enzyme activities upon exposure to SPP for 168h were evaluated. Results showed that SPP treatment was detrimental to C. vulgaris growth during the first 24-120h of exposure. The harmful effects, however, diminished over time (168h), even at an effective medium concentration of 226.37mg BL(-1) (the concentration of boron applied per liter of culture medium). A similar trend was observed for chlorophyll content (chlorophyll a and b) and indicated that the photosynthesis of C. vulgaris was not affected and that high levels of SPP may even promote chlorophyll synthesis. Superoxide dismutase and catalase activities of C. vulgaris increased during 24-120h exposure to SPP, but these activities gradually decreased as culture time progressed. In other words, the initial detrimental effects of synthetic SPP on C. vulgaris were temporary and reversible. This research provides a scientific basis for applications of SPP in the environment.

The long-term efficacy of an irradiation attenuated larval (L3) vaccine against Strongylus vulgaris was tested in ponies which were reared on pasture. Prior to foaling, mares were divided into two groups. One group of mares and foals received regular (eight weekly) treatment with ivermectin and the second group remained untreated. Half the foals in each pasture group were vaccinated at eight to ten weeks of age. Foals were weaned at three to four months of age and maintained on separate pastures. At eight to ten months of age, ponies were placed in box stalls and half of each treatment group were challenged with S. vulgaris (5 x 1000 L3). Clinical signs and lesions typical of acute verminous arteritis were found at necropsy in the ivermectin treated non-vaccinated challenged yearlings. Ivermectin treated vaccinated challenged yearlings did not show these clinical signs, had markedly reduced to absent arterial lesions and showed an 89 per cent reduction in arterial larval burdens post mortem. Significant differences in clinical signs, arterial lesions or arterial larval burdens were not seen between vaccinated and non-vaccinated foals reared without benefit of ivermectin treatment.

Recently, considerable attention has been focused on exploring the potential antioxidant properties of plant extracts or isolated products of plant origin. Prunella vulgaris var. lilacina is widely distributed in Korea, Japan, China, and Europe, and it continues to be used to treat inflammation, eye pain, headache, and dizziness. However, reports on the antioxidant activities of P. vulgaris var. lilacina are limited, particularly concerning the relationship between its phenolic content and antioxidant capacity. In this study, we investigated the antioxidant and anticancer activities of an ethanol extract from P. vulgaris var. lilacina and its fractions. Dried powder of P. vulgaris var. lilacina was extracted with ethanol, and the extract was fractionated to produce the hexane fraction, butanol fraction, chloroform fraction and residual water fraction. The phenolic content was assayed using the Folin-Ciocalteu colorimetric method. Subsequently, the antioxidant activities of the ethanol extract and its fractions were analyzed employing various antioxidant assay methods including DPPH, FRAP, ABTS, SOD activity and production of reactive oxygen species. Additionally, the extract and fractions were assayed for their ability to exert cytotoxic activities on various cancer cells using the MTT assay. We also investigated the expression of genes associated with apoptotic cell death by RT-PCR. The total phenolic contents of the ethanol extract and water fraction of P. vulgaris var. lilacina were 303.66 and 322.80 mg GAE/g dry weight (or fractions), respectively. The results showed that the ethanol extract and the water fraction of P. vulgaris var. lilacina had higher antioxidant content than other solvent fractions, similar to their total phenolic content. Anticancer activity was also tested using the HepG2, HT29, A549, MKN45 and HeLa cancer cell lines. The results clearly demonstrated that the P. vulgaris var. lilacina ethanol extract induced significant cytotoxic effects

Moxidectin was tested for efficacy in ponies against experimental infections of 56 day Strongylus vulgaris larvae and 11 day Parascaris equorum larvae. Three dosages of moxidectin were tested: 300 micrograms per kg live body weight, 400 micrograms per kg, and 500 micrograms per kg, and the vehicle served as control. Ponies were first infected with 600 S. vulgaris third-stage larvae (L3) on Experiment Day 0 and then with 3000 embryonated P. equorum eggs on Day 45. Moxidectin treatments were administered on Day 56 and necropsy examinations were performed on Day 91. Strongylus vulgaris fourth-stage (L4) and fifth-stage (L5) larvae were recovered at necropsy from the control ponies, in dissections of the cranial mesenteric artery and its branches (L4 and L5), and recovered from nodules in the wall of the cecum and ventral colon (L5). Parascaris equorum larvae were recovered from the small intestine of control ponies. Moxidectin was highly efficacious against S. vulgaris L4 and L5 at all three doses tested (99.6-100%), and appeared to be equally efficacious against P. equorum larvae (100%); however, control ponies had low levels of P. equorum infections compared to previous experimental infections performed using identical methods. This suggests that the prior S. vulgaris infection on Day 0 may have influenced the subsequent experimental P. equorum infection on Day 45 and contributed to the lower recovery.

In this study in vitro antileishmanial activity of various extracts of B. vulgaris also its active compoenent, berberine against promastigote and amastigote stages of L. tropica and L. infantum was evaluated, using MTT assay and in a macrophage model, respectively. Furthermore, infectivity rate and cytotoxicity effects of B. vulgaris and berberine in murine macrophage cells were investigated. The findings of optical density (OD) and IC50 indicated that B. vulgaris particulary berberine significantly (P<0.05) inhibited the growth rate of promastigote stage of L.tropica and L.infantum in comparison to meglumine antimoniate (MA). In addition, B. vulgaris and berberine significantly (P<0.05) decreased the mean number of amastigotes in each macrophage as compared with positive control. In the evaluation of cytotoxicity effects, it could be observed that berberine as compared with B. vulgaris exhibited more cytotoxicity against murine macrophages. Results also showed that when parasites were pre-incubated with B. vulgaris their ability to infect murine macrophages was significantly decreased. B.vulgaris particularly berberine exhibited potent in vitro leishmanicidal effects against L. tropica and L.infantum. Further works are required to evaluate the antileishmanial effects of B.vulgaris on Leishmania species using clinical settings.

We have explored interfacial interactions between a Mo–C terminated Mo{sub 2}BC(040) surface and an Al cluster using ab initio molecular dynamics. The Al cluster is disrupted and wets the Mo{sub 2}BC(040) surface. This can be understood based on the electronic structure. Across the Al–MoC interface C s–Al s hybridized states are formed. These bonds are stronger than the Al–Al intra-cluster bonds. Hence, the onset of Al adhesion is caused by bond formation across the Al–MoC interface. - Highlights: • Interfacial interactions between Mo{sub 2}BC and an Al cluster were explored. • Al forms bonds to C constituting the onset of Al adhesion on Mo{sub 2}BC. • These data are relevant for other carbide coatings.

The novel entity of "diffuse midline glioma, H3 K27M-mutant" has been defined in the 2016 revision of the World Health Organization (WHO) classification of tumors of the central nervous system (CNS). Tumors of this entity arise in CNS midline structures of predominantly pediatric patients and are associated with an overall dismal prognosis. They are defined by K27M mutations in H3F3A or HIST1H3B/C, encoding for histone 3 variants H3.3 and H3.1, respectively, which are considered hallmark events driving gliomagenesis. Here, we characterized 85 centrally reviewed diffuse gliomas on midline locations enrolled in the nationwide pediatric German HIT-HGG registry regarding tumor site, histone 3 mutational status, WHO grade, age, sex, and extent of tumor resection. We found 56 H3.3 K27M-mutant tumors (66%), 6 H3.1 K27M-mutant tumors (7%), and 23 H3-wildtype tumors (27%). H3 K27M-mutant gliomas shared an aggressive clinical course independent of their anatomic location. Multivariate regression analysis confirmed the significant impact of the H3 K27M mutation as the only independent parameter predictive of overall survival (P = 0.009). In H3 K27M-mutant tumors, neither anatomic midline location nor histopathological grading nor extent of tumor resection had an influence on survival. These results substantiate the clinical significance of considering diffuse midline glioma, H3 K27M-mutant, as a distinct entity corresponding to WHO grade IV, carrying a universally fatal prognosis. © The Author(s) 2017.

Fraser, P. D. K.

1999-10-01

A special prosecutor has been appointed by the British Columbia Government to assist the Royal Canadian Mounted Police (RCMP) in its investigation, and to render appropriate charging decisions in the matter of the circumstances surrounding the creation of IPC International Power Corporation (IPC) owned by a Mr. John N. Laxton, former Chairman of BC Hydro and his two children, and its joint venture with BC Hydro for the development of an international power project in Pakistan known as the Raiwind project. Of particular concerns were the conflict of interest breached by Mr. Laxton in loaning a substantial sum of money to a principal member of the Pakistani side of the joint venture, and by the former President and CEO of BC Hydro, Mr. John Sheehan, by his purchase of shares of IPC by a company owned by members of his family. In 1996 Mr. Sheehan's employment as President and CEO was terminated by BC Hydro for breaching internal conflict of interest guidelines and for failing to get approval from BC Hydro for the acquisition of IPC shares. Subsequently, Mr. Sheehan commenced an action against BC Hydro for wrongful dismissal, a claim which was upheld by the Supreme Court of British Columbia. The focus of the special prosecutor's criminal investigation ultimately became the conduct of Mr. Laxton and whether a charge could or should be laid under Section 122 of the Criminal Code. The outcome of his investigation, which is discussed in this report, was that there was no substantial likelihood of conviction under the breach or trust provisions of Section 122 with respect to the indirect purchases by Mr. Laxton of shares in IPC. Nor was there any reason to believe that a personal loan made in high-risk circumstances could be a benefit or advantage to the lender. Furthermore, the loan cannot be causally related to any loss or financial harm to BC Hydro. In fact, it could be argued that Mr. Laxton's private decision to make the loan was of real assistance in ensuring that the

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.

In this study, biosynthesis of self-assembled gold nanoparticles (GNPs) was accomplished using an aqueous extract of green microalga, Chlorella vulgaris. The optical, physical, chemical and bactericidal properties of the GNPs were investigated to identify their average shape and size, crystal nature, surface chemistry and toxicity, via UV-visible spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy and antimicrobial activity. The sizes of the spherical self-assembled cores of the synthesized GNPs ranged from 2 to 10 nm. The XRD patterns showed a (111) preferential orientation and the crystalline nature of the GNPs. The results of the FTIR analysis suggested that the peptides, proteins, phenol and flavonoid carried out the dual function of effective Au III reduction and successful capping of the GNPs. Human pathogen Candida albicans and Staphylococcus aureus were susceptible to synthesized aqueous GNPs. Thus, biosynthesis, stabilization and self-assembly of the GNPs by Chlorella vulgaris extract can be an example of green chemistry and effective drug in the medicinal field.
Black Carbon Aging from SOA Coatings and Coagulation with Diesel BC Emissions during SAAS at the PNNL Environmental Chamber

Black carbon (BC) is considered to be potentially the 2nd most important global warming factor behind CO2 (Bond et al., 2013). Uncertainties exist due to BC morphology and mixing state on the extent of the warming that it causes, e.g. Cappa et al., 2012. Core-shell BC is expected to enhance absorption by up to a factor of 2, but has yet to be observed to this extent from ambient data. Experiments were conducted during the Soot Aerosol Aging Study (SAAS) Laboratory Campaign at Pactific Northwest National Laboratory's Environmental Chamber in the winter of 2013-2014 to investigate the relationship between coatings and enhancements from diesel emissions. Direct on-line measurements were made with the single particle soot photometer (SP2) from fresh and aged BC from coating and coagulation experiments with secondary organic aerosol (SOA) formed in the chamber. BC measurements are coupled with photoactoustic measurements spanning the visible region to probe BC enhancements when mixed with SOA. Here we focus on the enhancements at 781 nm, that are tracked throughout SOA growth on BC, as determined from SP2 coating thicknesses. Thermal denuder (TD) experiments are conducted and enhancements are calculated from two different methods that agree well with each other, confirming the observed results. BC measurements are also compared with co-located measurements from SPLAT-II and filter analysis using SEM and TEM. BC coagulated with SOA produces minimal absorption enhancement values, whereas coatings are observed to have significant enhancement values at 300 degrees C, e.g. 1.3 for thickly coated BC. BC particles were coagulated with SOA in the chamber since this morphology has been observed in wildfire emissions (Sedlacek et al., 2012). Since we did not observe appreciable enhancements for the coagulated BC, we expect that ambient emissions dominated by this particle type to have enhancements due to other sources, such as brown carbon (BrC) that is often co-emitted (Saleh et

Isotretinoin is commonly used in the treatment of acne vulgaris. While one of the more common side-effects is cheilitis, we have observed an increased incidence of cheilitis prior to the commencement of systemic isotretinoin. The aim of this study was to assess the prevalence of cheilitis among acne vulgaris patients. A non-interventional cross-sectional study of patients with acne vulgaris. Patients with previous use of systemic retinoids were excluded. The patients were examined for signs and symptoms of cheilitis. Of a total of 400 patients, 134 (34%) had evidence of cheilitis at initial presentation. Two-thirds (63%) were female (P acne excorie, compared with only 8% of patients with no signs of cheilitis. Our findings suggest that cheilitis is quite common among acne vulgaris patients even before treatment with isotretinoin. © 2016 The Australasian College of Dermatologists.

Background: Acne vulgaris, a common human skin condition, is an inflammatory disease characterized by comedones, papules, nodules and possibly scarring. This study aimed to evaluate the efficacy of a combination of 5% dapsone gel plus oral isotretinoin in the treatment of acne vulgaris. Materials and Methods: A randomized, placebo-controlled, study was carried out on patients with moderate to severe acne. The patients were randomly divided in two groups: (dapsone gel and vehicle gel). All Patients were administered oral isotretinoin 20 mg daily and topical gel twice a day for 8 weeks. The Global Acne Assessment Score (GAAS), the number lesions and side-effects were documented at base line and weeks 4, 8 and 12. Results: A total of 58 patients (age range: 18-25 years) were included in our study. The number of lesions was significantly lower in the dapsone-treated group at all follow-up visits (P < 0.001). The mean GAAS score in the dapsone-treated group and in the Placebo-treated group decreased, but there was no statistical difference in two groups (P < 0.001). The side-effects on the dapsone-treated group were a mild burning sensation in 7 patients (24.13%), mild erythema of the skin and mild dryness in 4 (13.79%) and 3 (10.34%) cases respectively (P < 0.001). In our study, adverse effects were common but they were minor and tolerable. No clinically significant changes in laboratory parameters were observed (P < 0.001). Conclusions: Dapsone gel was an effective medication for patients who received isotretinoin for acne vulgaris treatment resulting in a significant reduction of the number of lesions. PMID:25250291

Arteritis due to Strongylus vulgaris is a well-known cause of colic in horses and donkeys. The current report describes a fatal incidence of arterial obstruction in cranial mesenteric artery caused by S. vulgaris infection in an adult donkey in which anthelmintic treatment was not regularly administered. Necropsy findings of the abdominal cavity revealed a complete cranial mesenteric arterial obstruction due to larvae of S. vulgaris, causing severe colic. To the authors' knowledge, a complete cranial mesenteric arterial obstruction due to verminous arteritis has rarely been described in horses and donkeys. Based on recent reports of fatal arterial obstruction due to S. vulgaris infection in donkeys, it may be evident to consider acute colic caused by this pathogenic parasite a re-emerging disease in donkeys and horses.

GanedenBC(30), a probiotic, has been shown to significantly increase T-cell production of TNF-alpha after ex vivo exposure to a strain of adenovirus (AdenoVI) or influenza A (H3N2 Texas strain [FluTex]). The current controlled study was designed to further evaluate the effect of GanedenBC(30) on immunological marker levels following viral exposure. Ten healthy subjects' baseline immunological marker levels were analyzed. Subjects consumed 1 capsule/day of GanedenBC(30) for 28 days and returned for post-treatment immunological marker evaluation. Subjects' baseline measurements served as their own control. All subjects completed the study with no adverse events; however, one subject was excluded from the final analysis based on a reasonable consideration as an outlier. CD3+CD69+ cells, IL-6, IL-8, interferon-gamma (IFN-gamma) and TNF-alpha levels were increased after exposure to AdenoVI and FluTex. IL-1beta levels also increased after exposure to AdenoVI but were decreased after ex vivo exposure to FluTex. CD3+CD69+ cells increased significantly (P = 0.023) after exposure to both viral strains. Differences in IL-8 levels after FluTex exposure achieved statistical significance (P = 0.039) as did IFN-gamma levels after AdenoVI exposure (P = 0.039). A regimen of one capsule per day containing 500 million CFU of GanedenBC30 may be a safe and effective option for enhancing the immunological response to common viral respiratory tract infections. 2010 Prous Science, S.A.U. or its licensors.

Semileptonic decays of B_c meson to S-wave charmonium states in the perturbative QCD approach

Rui, Zhou; Li, Hong; Wang, Guang-xin; Xiao, Ying

2016-01-01

Inspired by the recent measurement of the ratio of B_c branching fractions to J/ψπ"+ and J/ψμ"+ν_μ final states at the LHCb detector, we study the semileptonic decays of B_c meson to the S-wave ground and radially excited 2S and 3S charmonium states with the perturbative QCD approach. After evaluating the form factors for the transitions B_c → P,V, where P and V denote pseudoscalar and vector S-wave charmonia, respectively, we calculate the branching ratios for all these semileptonic decays. The theoretical uncertainty of hadronic input parameters are reduced by utilizing the light-cone wave function for the B_c meson. It is found that the predicted branching ratios range from 10"-"7 up to 10"-"2 and could be measured by the future LHCb experiment. Our prediction for the ratio of branching fractions (BR(B_c"+→J/Ψπ"+))/(BR(B_c"+→J/Ψμ"+ν_μ)) is in good agreement with the data. For B_c → Vlν_l decays, the relative contributions of the longitudinal and transverse polarization are discussed in different momentum transfer squared regions. These predictions will be tested on the ongoing and forthcoming experiments. (orig.)

Viruses have evolved unique strategies to evade or subvert autophagy machinery. Enterovirus A71 (EV-A71) induces autophagy during infection in vitro and in vivo. In this study, we report that EV-A71 triggers autolysosome formation during infection in human rhabdomyosarcoma (RD) cells to facilitate its replication. Blocking autophagosome-lysosome fusion with chloroquine inhibited virus RNA replication, resulting in lower viral titres, viral RNA copies and viral proteins. Overexpression of the non-structural protein 2BC of EV-A71 induced autolysosome formation. Yeast 2-hybrid and co-affinity purification assays showed that 2BC physically and specifically interacted with a N -ethylmaleimide-sensitive factor attachment receptor (SNARE) protein, syntaxin-17 (STX17). Co-immunoprecipitation assay further showed that 2BC binds to SNARE proteins, STX17 and synaptosome associated protein 29 (SNAP29). Transient knockdown of STX17, SNAP29, and microtubule-associated protein 1 light chain 3B (LC3B), crucial proteins in the fusion between autophagosomes and lysosomes) as well as the lysosomal-associated membrane protein 1 (LAMP1) impaired production of infectious EV-A71 in RD cells. Collectively, these results demonstrate that the generation of autolysosomes triggered by the 2BC non-structural protein is important for EV-A71 replication, revealing a potential molecular pathway targeted by the virus to exploit autophagy. This study opens the possibility for the development of novel antivirals that specifically target 2BC to inhibit formation of autolysosomes during EV-A71 infection.
[Acne vulgaris: morphologic, endocrinologic and psychosomatic aspects].

25 male patients suffering from acne vulgaris were examined by means of endocrinological, morphological, and 5 psychometric procedures in order to check the correlations and interactions between the psychological and dermatological aspects of the disease. In comparison with a control group, the acne patients did not show any striking endocrinological abnormalities; we found no correlation between the extensiveness of the lesions and the level of DHEA sulphate. All the psychological tests yielded results deviating from those achieved by the representative controls, but they were comparable with those of other patients suffering from psychosomatic diseases. The individual feeling of being "disfigured" found its expression in self-consciousness, lack of trust in his/her own body, as well as the clinically relevant difference between his/her conception of self and the ideal of self. During times of enhanced psychosocial strains subjectively assumed by the patients, the lesions increased and the patients were disturbed in social interaction and communication. Surprisingly, we did not find any correlation between the clinical status and significant psychometric findings. Our results show that in acne vulgaris, the individual experience of wanting physical attractiveness, associated with a predominantly neurotic depressive personal structure, may play a central part in a disturbed process of interaction with the environment and suggest the influence of psychic factors in the pathogenesis of acne vulgaris.

Full Text Available BACKGROUND Acne vulgaris is a highly prevalent chronic inflammatory disease of pilosebaceous unit affecting teenagers and young adults. Prognosis of acne is generally good, especially in mild acne. But, this disease reduces the self-esteem, their sense of identity and can severely compromise quality of life. All clinicians caring for children and adolescents should be familiar with this problem. Early diagnosis, proper treatment and timely counselling reduce the overall impact of disease to individuals. MATERIALS AND METHODS This is a prospective study conducted in the Department of Dermatology at Government Medical College, Kottayam, Kerala, in 200 patients who presented to the outpatient clinic with a clinical diagnosis of acne vulgaris who have not yet received any medical treatment for the disease and consented to participate in the study. RESULTS Male-to-female ratio of 1.43:1. 61.5% patients were in the 2nd decade. 4% were more than 30 years old. Duration of the disease at the time of presentation ranged from 3 weeks to 30 years. 42.5% complained of mild itching and 18.5% had burning sensation. 48.5% attribute exacerbation of disease after food intake. 72.5% acne patients had seborrhoea. Hirsutism and Acanthosis nigricans were present in 7.31% and 4.87% female patients, respectively. 50% with hirsutism and 25% with Acanthosis nigricans had polycystic ovarian disease and severe grades of acne. 25.6% females complained of premenstrual exacerbation of the disease. 26% of the patients showed exacerbation in summer. Smokers had severe grades of acne vulgaris compared to nonsmokers. Comedones were present in all and they were the predominant lesions in majority. Inflammatory papules were the 2nd most common lesions. Severe grades of acne were more common in patients with age ≥20 years. Severity of the disease increases with long duration of the disease. Relatively high incidence of post-acne scarring and post-inflammatory hyperpigmentation was

Highlights: • Cyanobacteria and C. vulgaris were compared in terms of growth and methane production. • Biomasses were subjected to anaerobic digestion without applying any disruption method. • Cyanobacteria showed an increased methane yield in comparison with C. vulgaris. - Abstract: The aim of the present study was to compare cyanobacteria strains (Aphanizomenon ovalisporum, Anabaena planctonica, Borzia trilocularis and Synechocystis sp.) and microalgae (Chlorella vulgaris) in terms of growth rate, biochemical profile and methane production. Cyanobacteria growth rate ranged 0.5–0.6 day −1 for A. planctonica, A. ovalisporum and Synecochystis sp. and 0.4 day −1 for B. tricularis. Opposite, C. vulgaris maximum growth rate was double (1.2 day −1 ) than that of cyanobacteria. Regarding the methane yield, microalgae C. vulgaris averaged 120 mL CH 4 g COD in −1 due to the presence of a strong cell wall. On the other hand, anaerobic digestion of cyanobacteria supported higher methane yields. B. trilocularis and A. planctonica presented 1.42-fold higher methane yield than microalgae while this value was raised to approximately 1.85-fold for A. ovalisporum and Synechochystis sp. In the biogas production context, this study showed that the low growth rates of cyanobacteria can be overcome by their increased anaerobic digestibility when compared to their microalgae counterpartners, such is the case of C. vulgaris

Conventional fossil fuels are facing a global challenge which lead scientists to explore alternative fuel production from biological sources. The algae-based fuels are gaining rapid attention as it has potential to replace petroleum-based fuels. An indigenous high lipid producing microalgae was isolated from a freshwater pond in the KwaZulu-Natal province of South Africa. The isolate was later identified as Chlorella vulgaris, based on partial 28S large subunit ribosomal RNA gene sequence. The growth kinetics, pyrolytic characteristics and photosynthetic efficiency of Chlorella was evaluated in vitro. The optimized conditions for higher biomass yield of the selected strain were at 4% CO(2), 0.5 g l(-1) NO(3) and 0.04 g l(-1) PO(4), respectively. The pulse amplitude modulation results indicated that C. vulgaris could withstand a light intensity ranging from 150 to 350 μmol photons m(-2)s(-1). Further increase in light intensity resulted in a decline of the electron transport rate. Carbon fixation rate, lipid content and calorific value of C. vulgaris was 6.17 mg l(-1)h(-1), 21% and 17.44 kJ g(-1), respectively. The pyrolitic studies under inert atmosphere at different heating rates of 15, 30, 40 and 50°C min(-1) from ambient temperature to 800°C showed that the overall final weight loss recorded for the four different heating rates was in the range of 78.9-81%. These studies could be useful to appraise the biofuel potential of the isolated C. vulgaris strain, which can later be taken for pilot scale production.

EVALUATION OF THE FLOCCULATION EFFICIENCY OF Chlorella vulgaris MEDIATED BY Moringa oleifera SEED UNDER DIFFERENT FORMS: FLOUR, SEED CAKE AND EXTRACTS OF FLOUR AND CAKE

Directory of Open Access Journals (Sweden)

C. M. L. Lapa Teixeira

Full Text Available Abstract Flocculation as a pre-separation method can help make production of biodiesel from microalgae economically feasible. In a previous study, Moringa oleifera seed flour (1 g.L-1 was shown to be a very efficient flocculant for Chlorella vulgaris, a microalga with high potential for biodiesel production. In this study, several aspects of C vulgaris flocculation mediated by Moringa were investigated in order to optimize the separation of this biomass. Flocculation efficiency was the same with seeds from different origins and lots. The stationary growth stage was best for harvesting C vulgaris cells to carry out flocculation efficiently (93%. The use of flour extracts and cake extracts generated the best cost-benefit ratio (flocculation efficiency from 78 to 97% with a saving in mass of seed of 75%. The highest efficiency was reached with extracts prepared with seawater and NaCl solutions which have high salt concentration. Reasonable stability of the extract allows its use for up to two weeks, provided it is kept at low temperature (4 ºC.

Solid phase IC were prepared by coating microwells with heat-aggregated bovine serum albumin (BSA) followed by incubation with rabbit IgM anti-BSA antibody. The IC were reacted with human serum at 37 degrees C....... The binding of C3b-iC3b was determined by use of biotinylated F(ab')2 antibodies to C3b-C3c and avidin-coupled alkaline phosphatase. The incorporation of C3b-iC3b into solid-phase IgM-IC increased when increasing amounts of IgM antibody were reacted with the antigen. The binding reaction was slow, reaching...

Biological invasion is regarded as one of the greatest environmental problems facilitated by globalization. Some hypotheses about the invasive mechanisms of alien invasive plants consider the plant–herbivore interaction and the role of plant defense in this interaction. For example, the “Shift Defense Hypothesis” (SDH) argues that introduced plants evolve higher levels of qualitative defense chemicals and decreased levels of quantitative defense, as they are released of the selective pressures from specialist herbivores but still face attack from generalists. Common groundsel (Senecio vulgaris), originating from Europe, is a cosmopolitan invasive plant in temperate regions. As in other Senecio species, S. vulgaris contains pyrrolizidine alkaloids (PAs) as characteristic qualitative defense compounds. In this study, S. vulgaris plants originating from native and invasive ranges (Europe and China, respectively) were grown under identical conditions and harvested upon flowering. PA composition and concentration in shoot and root samples were determined using Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS). We investigated the differences between native and invasive S. vulgaris populations with regard to quantitative and qualitative variation of PAs. We identified 20 PAs, among which senecionine, senecionine N-oxide, integerrimine N-oxide and seneciphylline N-oxide were dominant in the roots. In the shoots, in addition to the 4 PAs dominant in roots, retrorsine N-oxide, spartioidine N-oxide and 2 non-identified PAs were also prevalent. The roots possessed a lower PA diversity but a higher total PA concentration than the shoots. Most individual PAs as well as the total PA concentration were strongly positively correlated between the roots and shoots. Both native and invasive S. vulgaris populations shared the pattern described above. However, there was a slight trend indicating lower PA diversity and lower total PA concentration in invasive S. vulgaris

Full Text Available We evaluated the spatiotemporal distributions of black carbon (BC and particulate matters with aerodynamic diameters of less than 2.5 m (PM2.5 concentrations at urban diesel engine emission (DEE hotspots of South Korea. Concentrations of BC and PM2.5 were measured at the entrance gate of two diesel bus terminals and a train station, in 2014. Measurements were conducted simultaneously at the hotspot (Site 1 and at its adjacent, randomly selected, residential areas, apartment complex near major roadways, located with the same direction of 300 m (Site 2 and 500 m (Site 3 away from Site 1 on 4 different days over the season, thrice per day; morning (n = 120 measurements for each day and site, evening (n = 120, and noon (n = 120. The median (interquartile range PM2.5 ranged from 12.6 (11.3–14.3 to 60.1 (47.0–76.0 μg/m3 while those of BC concentrations ranged from 2.6 (1.9–3.7 to 6.3 (4.2–10.3 μg/m3. We observed a strong relationship of PM2.5 concentrations between sites (slopes 0.89–0.9, the coefficient of determination 0.89–0.96 while the relationship for BC concentrations between sites was relatively weak (slopes 0.76–0.85, the coefficient of determination 0.54–0.72. PM2.5 concentrations were changed from 4% to 140% by unit increase of BC concentration, depending on site and time while likely supporting the necessity of monitoring of BC as well as PM2.5, especially at urban DEE related hotspot areas.

Full Text Available Arteritis due to Strongylus vulgaris is a well-known cause of colic in horses and donkeys. The current report describes a fatal incidence of arterial obstruction in cranial mesenteric artery caused by S. vulgaris infection in an adult donkey in which anthelmintic treatment was not regularly administered. Necropsy findings of the abdominal cavity revealed a complete cranial mesenteric arterial obstruction due to larvae of S. vulgaris, causing severe colic. To the authors' knowledge, a complete cranial mesenteric arterial obstruction due to verminous arteritis has rarely been described in horses and donkeys. Based on recent reports of fatal arterial obstruction due to S. vulgaris infection in donkeys, it may be evident to consider acute colic caused by this pathogenic parasite a re-emerging disease in donkeys and horses.

Light is one of the most important factors affecting microalgae growth and biochemical composition. The influence of illumination on Chlorella vulgaris cultivated with diluted monosodium glutamate wastewater (MSGW) was investigated. Six progressive illumination intensities (0, 30, 90, 150, 200 and 300μmol·m(-2)s(-1)), were used for C. vulgaris cultivation at 25°C. Under 150μmol·m(-2)s(-1), the corresponding specific light intensity of 750×10(-6)μmol·m(-2)s(-1) per cell, algae obtained the maximum biomass concentration (1.46g·L(-1)) on the 7th day, which was 3.5 times of that under 0μmol·m(-2)s(-1), and the greatest average specific growth rate (0.79 d(-1)) in the first 7days. The results showed the importance role of light in mixotrophic growth of C. vulgaris. High light intensities of 200 and 300μmol·m(-2)s(-1) would inhibit microalgae growth to a certain degree. The algal lipid content was the greatest (30.5%) at 150μmol·m(-2)s(-1) light intensity, which was 2.42 times as high as that cultured in dark. The protein content of C. vulgaris decreased at high light intensities of 200 and 300μmol·m(-2)s(-1). The effect of irradiance on carbohydrate content was inversely correlated with that on protein. The available light at an appropriate intensity, not higher than 200μmol·m(-2)s(-1), was feasible for economical cultivation of C. vulgaris in MSGW. Copyright © 2016 Elsevier B.V.

Highlights: • Methane production of microalgae biomass is hampered by their cell wall. • Pretreatment should be designed in accordance to the microalgae specie. • Fresh Chlamydomonas reinhardtii exhibited high anaerobic biodegradability. • Chlorella vulgaris anaerobic biodegradability was enhanced by 50% using protease pretreatment. - Abstract: The effect of enzymatic hydrolysis on microalgae organic matter solubilisation and methane production was investigated in this study. Even though both biomasses, Chlamydomonas reinhardtii and Chlorella vulgaris, exhibited similar macromolecular distribution, their cell wall composition provided different behaviors. The addition of carbohydrolase (Viscozyme) and protease (Alcalase) resulted in high carbohydrates and protein solubilisation on both biomasses (86–96%). Despite the high carbohydrate solubilisation with the carbohydrolase, methane production was enhanced by 14% for C. vulgaris, while hydrolyzed C. reinhardtii did not show any improvement. The addition of protease to C. reinhardtii increased methane production by 1.17-fold. The low enhancement achieved together with the inherent high biodegradability of this biomass would not justify the cost associated to the enzyme addition. On the other hand, C. vulgaris hydrolyzed with the protease resulted in 86% anaerobic biodegradability compared to 54% of the raw biomass. Therefore, the application of protease prior anaerobic digestion of C. vulgaris could be a promising approach to decrease the energetic input required for cell wall disruption

Acne vulgaris is known to impair many aspects of quality of life. However, the correlation of this impairment with clinical severity remains equivocal despite various school, community and hospital-based studies. A hospital-based study was undertaken to measure the impairment of quality of life of patients of acne vulgaris and correlate it with the severity of lesions. This was a cross-sectional, questionnaire-based study in a cohort of 100 patients of acne vulgaris attending the outpatient department of our referral hospital. A physician measured the severity of lesions using the global acne grading system, and patients assessed quality of life by completing a questionnaire (Cardiff acne disability index). A correlation of these two was done; some additional correlations were brought out through demographic data collected from the patients. There was no correlation between the severity of acne vulgaris and an impaired quality of life. Patients who consumed alcohol and/or smoked cigarettes were found to have an impaired quality of life. While the severity of acne progressively lessened in older patients, the impact on quality of life increased. The sample size was small and there was a lack of guaranteed reliability on the self-reported quality of life. The severity of acne vulgaris does not correlate with impairment in quality of life.

In this paper, we present a new automatic diagnosis method for facial acne vulgaris which is based on convolutional neural networks (CNNs). To overcome the shortcomings of previous methods which were the inability to classify enough types of acne vulgaris. The core of our method is to extract features of images based on CNNs and achieve classification by classifier. A binary-classifier of skin-and-non-skin is used to detect skin area and a seven-classifier is used to achieve the classification task of facial acne vulgaris and healthy skin. In the experiments, we compare the effectiveness of our CNN and the VGG16 neural network which is pre-trained on the ImageNet data set. We use a ROC curve to evaluate the performance of binary-classifier and use a normalized confusion matrix to evaluate the performance of seven-classifier. The results of our experiments show that the pre-trained VGG16 neural network is effective in extracting features from facial acne vulgaris images. And the features are very useful for the follow-up classifiers. Finally, we try applying the classifiers both based on the pre-trained VGG16 neural network to assist doctors in facial acne vulgaris diagnosis.

The toxic effects of ethyl cinnamate on the photosynthetic and physiological characteristics of Chlorella vulgaris were studied based on chlorophyll fluorescence and flow cytometry analysis. Parameters, including biomass, F v/F m (maximal photochemical efficiency of PSII), ФPSII (actual photochemical efficiency of PSII in the light), FDA, and PI staining fluorescence, were measured. The results showed the following: (1) The inhibition on biomass increased as the exposure concentration increased. 1 mg/L ethyl cinnamate was sufficient to reduce the total biomass of C. vulgaris. The 48-h and 72-h EC50 values were 2.07 mg/L (1.94–2.20) and 1.89 mg/L (1.82–1.97). (2) After 24 h of exposure to 2–4 mg/L ethyl cinnamate, the photosynthesis of C. vulgaris almost ceased, manifesting in ФPSII being close to zero. After 72 h of exposure to 4 mg/L ethyl cinnamate, the F v/F m of C. vulgaris dropped to zero. (3) Ethyl cinnamate also affected the cellular physiology of C. vulgaris, but these effects resulted in the inhibition of cell yield rather than cell death. Exposure to ethyl cinnamate resulted in decreased esterase activities in C. vulgaris, increased average cell size, and altered intensities of chlorophyll a fluorescence. Overall, esterase activity was the most sensitive variable. PMID:26101784

Full Text Available Plant proteins substitutes of fishmeal in aquafeed are usually lacking in some essential amino acids and fatty acids. The microalgae Chlorella vulgaris has good-quality protein with amino acids rich in methionine, lysine and alanine. Four novel diets having C. vulgaris as the main source of protein were produced for African catfish Clarias gariepinus with an initial average weight of 1.09 ± 0.05 g. The diets were labeled Feed 1 (F1 to feed 4 (F4. The treatment diets were included 25% (F1, 15% (F2, 5% (F3 and 0% (F4 green algae meal. The basal ingredients of the feed were corn (maize included as F1, 40%, F2, 43%, F3, 53% and F4, 43%; and millet meal, which varied in F1 as 23%, F2, 30%, F3, 30% and F4, 30%. The ingredients were preconditioned at 110 °C and pelleted. Post-fingerling African catfish were stocked at 10 fish per aquarium. There were three replicate aquariums for each feed type and the fish were fed for 60 d. The specific growth rate was best for the catfish fed with 25% C. vulgaris diet 7.86 ± 0% day−1, and worst at 6.77 ± 0.07% day−1 for the control group F4, 0% algal meal. The food conversion ratio (FCR was lowest (1.88 ± 0.02 for 25% algal meal diet (F1 and highest (2.98 ± 0.01 for the 0% algal meal diet F4. Similarly, catfish had average weight gain of 121.02 ± 0.04 g for those fed with F1 compared to 62.50 ± 0.0 g for those fed with 0% algae F4. Protein efficiency ratio was highest for the F1-fed fish (2.46 ± 0.22 and lowest for those fed with F4 (2.02 ± 0.09. The hepatosomatic index was lowest for F1-fed fish (1.48 ± 0.01 and highest for catfish fed with F4 (2.50 ± 0.59. Based on the results, C. vulgaris is a good protein source for African catfish and can also substitute fishmeal in the catfish diets.

This document presented an independent critique and review of the British Columbia (BC) 2007 energy plan. The critique focused on BC hydro-related policies in the energy plan, and was presented in three policy papers. The first paper addressed self-sufficiency and insurance issues. It examined the need for new sources of electricity supply in terms of imports and other market purchases that are currently used to meet BC Hydro's requirements. The second paper addressed BC Hydro electricity rates and the impacts and costs of buying high and selling low. It identified the impacts and costs of the low electricity rate policy in the energy plan, a policy that would inflate the demand for electricity and exaggerate the need for new sources of power caused by the self-sufficiency and insurance policies in the energy plan. Specifically, the second paper discussed BC Hydro rates under the energy plan, the limitations of power smart programs, distributional issues and alternative strategy. The third paper addressed supply issues in the energy plan, with particular reference to targeting low value/high cost resources. It focused on the types of resources BC Hydro had to acquire. It specifically addressed the pressure to acquire run-of-river and wind energy which, despite their superficial appeal, are low in value and high in cost, and could have significant environmental impact. It was concluded that despite the attempt to address environmental concerns, the province's energy plan is designed to artificially increase the market for new independent power producer supply. 76 refs., 9 tabs., 4 figs

Full Text Available In order to test the effect of two microbial inoculants (obtained from red and black mangrove roots on the growth and stability of mangrove and watermelon plants, four treatments were carried out in San Andres Island, Colombia. The treatments consisted in the application of the inoculants in: A. germinans propagules collected in a mangrove area, and then individually planted in gavels with sun-pasteurized soil (in order to decrease the microbial load, A. germinans and R. mangle plants collected in the proximity of nursery trees, A. germinans and R. mangle planted and maintained in nursery, and in Citrullus vulgaris seeds planted in a traditional cultivar without chemical fertilizers. The growth and vegetative development variables were: number of nodes, number of leaves and steam length. The inoculants (phosphate solubilizing microorganisms -PSM- and nitrogen fixing bacteria -NFB- were applied in the mentioned vegetable material, doing measures during three months. The results show a positive effect on growth measured by steam length in plants treated specifically with the inoculants in C. vulgaris and A. germinans seedlings maintained in nursery.

Acne vulgaris is a common dermatologic disease in African patients, as well as in Caucasians. Our report evaluates the safety and efficacy of adapalene gel 0.1% in African patients with acne vulgaris. We used a 12-week, 2-center, open-label, noncomparative study of adapalene gel 0.1% in 65 African patients with acne vulgaris to assess the drug's effect on hyperpigmented lesions in people with dark skin. The study demonstrated that the progressive and significant improvements in lesion counts and global acne grades produced by adapalene in African patients were paralleled by significant improvements in the degree of hyperpigmentation of acne lesions. During treatment with adapalene, less than 5% of patients reported moderate or severe skin irritation at any time during the study, and the incidence of skin oiliness decreased markedly. We conclude that adapalene gel 0.1% was well tolerated and highly effective in African patients with acne vulgaris and was found to reduce hyperpigmentation.

Full Text Available To avoid predation, octopuses select and actively modify shelters (also called dens in the substratum, where they remain most of the time, especially during daylight hours. The main questions that this study deals with are: Is den availability a significant constraint for the distribution of Octopus vulgaris on soft sediment? What kind of dens does O. vulgaris use on soft sediment and what factors affect the selection of one type instead of another? With population density measurements by SCUBA diving and enrichment experiments with artificial dens, we concluded that the availability of solid materials necessary for den construction is a limiting factor for the distribution of O. vulgaris on soft sediment. O. vulgaris used four different types of den on soft sediment: well (a vertical hole in the sediment, rock/stone (the octopus uses a rock or a large stone to dig a cavity under it, shell (an empty shell is used, human origin (a solid material of human origin is used. The relative proportion of the four types of den in the areas studied was: 38.7% human origin, 29.7% well, 21.5% rock/stone, 2.9% shell. Also, 7.3% of the octopuses were found outside their den. The main types of den were found in different relative proportions in relation to the depth, the distance from shore, the octopus size and the granulometry of the sediment.

Improving the charge carrier mobility of solution-processable organic semiconductors is critical for the development of advanced organic thin-film transistors and their application in the emerging sector of printed electronics. Here, a simple method is reported for enhancing the hole mobility in a wide range of organic semiconductors, including small-molecules, polymers, and small-molecule:polymer blends, with the latter systems exhibiting the highest mobility. The method is simple and relies on admixing of the molecular Lewis acid B(C6F5)(3) in the semiconductor formulation prior to solution deposition. Two prototypical semiconductors where B(C6F5)(3) is shown to have a remarkable impact are the blends of 2,8-difluoro-5,11-bis(triethylsilylethynyl)anthradithiophene:poly(triarylamine) (diF-TESADT:PTAA) and 2,7-dioctyl[1]-benzothieno[3,2-b][1]benzothiophene:poly(indacenodithiophene-co-benzothiadiazole) (C8-BTBT:C16-IDTBT), for which hole mobilities of 8 and 11 cm(2) V-1 s(-1), respectively, are obtained. Doping of the 6,13-bis(triisopropylsilylethynyl)pentacene:PTAA blend with B(C6F5)(3) is also shown to increase the maximum hole mobility to 3.7 cm(2) V-1 s(-1). Analysis of the single and multicomponent materials reveals that B(C6F5)(3) plays a dual role, first acting as an efficient p-dopant, and secondly as a microstructure modifier. Semiconductors that undergo simultaneous p-doping and dopant-induced long-range crystallization are found to consistently outperform transistors based on the pristine materials. Our work underscores Lewis acid doping as a generic strategy towards high performance printed organic microelectronics.

Analysis of the single and multicomponent materials reveals that B(C6F5)(3) plays a dual role, first acting as an efficient p-dopant, and secondly as a microstructure modifier. Semiconductors that undergo simultaneous p-doping and dopant-induced long-range crystallization are found to consistently outperform transistors based on the pristine materials. Our work underscores Lewis acid doping as a generic strategy towards high performance printed organic microelectronics.

First-principles calculations are used to explore the strong binding of lithium to boron- and carbon-doped BC2N monolayers (BC2NBC and BC2NCN, respectively) without the formation of lithium clusters. In comparison to BC2N and BC2NCB, lithium-decorated BC2NBC and BC2NCN systems possess stronger s-p and p-p hybridization and, hence, the binding energy is higher. Lithium becomes partially positively charged by donating electron density to the more electronegative atoms of the sheet. Attractive van der Waals interactions are responsible for binding hydrogen molecules around the lithium atoms. Each lithium atom can adsorb three hydrogen molecules on both sides of the sheet, with an average hydrogen binding energy of approximately 0.2 eV, which is in the range required for practical applications. The BC2NBC-Li and BC2NCN-Li complexes can serve as high-capacity hydrogen-storage media with gravimetric hydrogen capacities of 9.88 and 9.94 wt %, respectively. © 2014 WILEY-VCH Verlag GmbH & Co.

Full Text Available Microalgae have the potential of consuming high amounts of nitrogen and phosphorus from wastewater; thus, avoiding the risk of eutrophication of the water bodies. Nevertheless, ammonium can usually inhibit the growth of microalgae. Tolerance to ammonium is specific of each strain; so, the development of tertiary wastewater treatment proposals, employing microalgae, has as a first step the study of its tolerance to N-NH3. In this work, the tolerance of Chlorella vulgaris to N-NH3, using mineral medium, was studied. Afterward, C. vulgaris was used to remove nitrogen and phosphorus from a real wastewater. The maximal biomass concentration was reached at 66 ppm N-NH3 (0.49 gL-1 with the complete depletion of the ammonium and a phosphorus consumption of 2 mgPi L-1d-1 in all the experiments. When C. vulgaris was grown in real wastewater, the final biomass concentration was 0.267 g L-1 and the nutrients (N and P were totally consumed after 3 days. According with these results, this strain of Chlorella has the potential for the removal of nitrogen and phosphorus from tertiary wastewater and the biomass produced in the process can be used for the production of high value products, such as pigments, proteins, carbohydrate or used for animal feed.

The response of Desulfovibrio vulgaris Hildenborough to salt adaptation (long-term NaCl exposure) was examined by physiological, global transcriptional, and metabolite analyses. The growth of D. vulgaris was inhibited by high levels of NaCl, and the growth inhibition could be relieved by the addition of exogenous amino acids (e.g., glutamate, alanine, tryptophan) or yeast extract. Salt adaptation induced the expression of genes involved in amino acid biosynthesis and transport, electron transfer, hydrogen oxidation, and general stress responses (e.g., heat shock proteins, phage shock proteins, and oxidative stress response proteins). Genes involved in carbon metabolism, cell motility, and phage structures were repressed. Comparison of transcriptomic profiles of D. vulgaris responses to salt adaptation with those of salt shock (short-term NaCl exposure) showed some similarity as well as a significant difference. Metabolite assays showed that glutamate and alanine were accumulated under salt adaptation, suggesting that they may be used as osmoprotectants in D. vulgaris. A conceptual model is proposed to link the observed results to currently available knowledge for further understanding the mechanisms of D. vulgaris adaptation to elevated NaCl.

Curcumin (Cur), a polyphenols with pharmacological function, was successfully encapsulated in algae (Alg) cell (Chlorella vulgaris) as confirmed by fluorescence microscopy, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and Fourier transform-infrared spectroscopy (FT-IR). Fluorescence micrographs, TGA, DSC and FTIR spectra suggested the hypothesis inclusion Cur in Nano-empty spaces inside cell wall of Alg. The TGA analysis showed that the thermal stability of Alg and Cur at algae/curcumin complex was 3.8% and 33% higher than their free forms at 0-300°C and 300-600°C ranges, respectively. After encapsulation in Alg cells, the photostability of Cur was enhanced by about 2.5-fold. Adsorption isotherm of Cur into Alg was fitted with the Freundlich isotherm. The microcapsules were loaded with Cur up to about 55% w/w which is much higher than other reported bio-carriers. In conclusion, the data proved that Chlorella vulgaris cell can be used as a new stable carrier for Cur. Copyright © 2016 Elsevier Ltd. All rights reserved.

Strobilurins have been reported highly toxic to non-target aquatic organisms but few illustrated how they cause toxic effects on algae. This study investigated the acute toxicity of Kresoxim-methy (KRE), Pyraclostrobin (PYR), Trifloxystrobin (TRI) and Picoxystrobin (PIC) on two algae and their toxicity mechanisms. Four strobilurins showed lower toxic effects on Chlorella pyrenoidsa but higher on Chlorella vulgaris. bc1 complex activities in C. vulgaris were significantly inhibited by all strobilurins, suggesting bc 1 complex might be the target of strobilurin toxicity in algae. Moreover, SOD, CAT and POD activities were significantly up-regulated by all doses of KRE, PYR and PIC. In contrast, low concentrations of TRI stimulated SOD and POD activities but highest concentration significantly inhibited those activities. Comet assays showed damaged DNA in C. vulgaris by four strobulirins, suggesting their potential genotoxic threats to algae. The results illustrated acute toxicity by strobulirins on algae and their possible toxicity mechanisms. Copyright © 2018 Elsevier B.V. All rights reserved.

Accumulation of intra-cellular phosphate, as polyphosphate, was measured when the microalga Chlorella vulgaris was immobilized in alginate with either of two wild-type strains of the microalgae growth-promoting bacterium Azospirillum brasilense or their corresponding IAA-attenuated mutants. Wild type strains of A. brasilense induced higher amounts of intra-cellular phosphate in Chlorella than their respective mutants. Calculations comparing intra-cellular phosphate accumulation by culture or net accumulation by the cell and the amount of IAA that was produced by each of these strains revealed that higher IAA was linked to higher accumulations of intra-cellular phosphate. Application of four levels of exogenous IAA reported for A. brasilense and their IAA-attenuated mutants to cultures of C. vulgaris enhanced accumulation of intra-cellular phosphate; the higher the content of IAA per culture or per single cell, the higher was the amount of accumulated phosphate. When an IAA-attenuated mutant was complemented with exogenous IAA, accumulation of intra-cellular phosphate at the culture level was even higher than phosphate accumulation with the respective wild type strains. When calculating the net accumulation of intra-cellular phosphate in the complementation experiment, net intra-cellular phosphate induced by the IAA-attenuated mutant was completely restored and was similar to the wild strains. We propose that IAA produced by A. brasilense is linked to polyphosphate accumulation in C. vulgaris. Copyright © 2015 Institut Pasteur. Published by Elsevier Masson SAS. All rights reserved.

International Nuclear Information System (INIS)

Bellian, J.G.

1984-01-01

Prototype samples of plastic scintillators containing up to 10% by weight of natural boron have been produced. The maximum size scintillators made to date are 28 mm dia. x 100 mm long. Rods containing up to 2% boron are now made routinely and work is progressing on higher concentrations. The plastics are clear and emit the same blue fluorescence as other common plastic scintillators. It is expected that rods up to 3'' dia. containing 5% boron will be produced during the next few months. BC-454 is particularly useful in neutron research, materials studies, some types of neutron dosimetry, and monitoring of medium to high energy neutrons in the presence of other types radiation. It combines attractive features that enhance its usefulness to the physics community
Periplasmic Cytochrome c(3) of Desulfovibrio vulgaris Is Directly Involved in H2-Mediated Metal but Not Sulfate Reduction

International Nuclear Information System (INIS)

Elias, Dwayne A.; Suflita, Joseph M.; McInerney, Michael J.; Krumholz, Lee R.

2004-01-01

Kinetic parameters and the role of cytochrome c3 in sulfate, Fe(III), and U(VI) reduction were investigated in Desulfovibrio vulgaris Hildenborough. While sulfate reduction followed Michaelis-Menten kinetics (Km 220 uM), loss of Fe(III) and U(VI) was first-order at all concentrations tested. Initial reduction rates of all electron acceptors were similar for cells grown with H2 and sulfate, while cultures grown using lactate and sulfate had similar rates of metal loss but lower sulfate reduction activities. The similarities in metal, but not sulfate, reduction with H2 and lactate suggest divergent pathways. Respiration assays and reduced minus oxidized spectra were carried out to determine c-type cytochrome involvement in electron acceptor reduction. c-type cytochrome oxidation was immediate with Fe(III) and U(VI) in the presence of H2, lactate, or pyruvate. Sulfidogenesis occurred with all three electron donors and effectively oxidized the c-type cytochrome in lactate or pyruvate-reduced, but not H2-reduced cells. Correspondingly, electron acceptor competition assays with lactate or pyruvate as electron donors showed that Fe(III) inhibited U(VI) reduction, and U(VI) inhibited sulfate loss. However, sulfate reduction was slowed but not halted when H2 was the electron donor in the presence of Fe(III) or U(VI). U(VI) loss was still impeded by Fe(III) when H2 was used. Hence, we propose a modified pathway for the reduction of sulfate, Fe(III), and U(VI) which helps explain why these bacteria cannot grow using these metals. We further propose that cytochrome c3 is an electron carrier involved in lactate and pyruvate oxidation and is the reductase for alternate electron acceptors with higher redox potentials than sulfate

Full Text Available Background: Platelet rich plasma-platelet concentrate (PRP-PC, buffy coat poor-platelet concentrate (BC-PC, and apheresis-PC were prepared and their quality parameters were assessed. Study Design: In this study, the following platelet products were prepared: from random donor platelets (i platelet rich plasma - platelet concentrate (PRP-PC, and (ii buffy coat poor- platelet concentrate (BC-PC and (iii single donor platelets (apheresis-PC by different methods. Their quality was assessed using the following parameters: swirling, volume of the platelet concentrate, platelet count, WBC count and pH. Results: A total of 146 platelet concentrates (64 of PRP-PC, 62 of BC-PC and 20 of apheresis-PC were enrolled in this study. The mean volume of PRP-PC, BC-PC and apheresis-PC was 62.30±22.68 ml, 68.81±22.95 ml and 214.05±9.91 ml and ranged from 22-135 ml, 32-133 ml and 200-251 ml respectively. The mean platelet count of PRP-PC, BC-PC and apheresis-PC was 7.6±2.97 x 1010/unit, 7.3±2.98 x 1010/unit and 4.13±1.32 x 1011/unit and ranged from 3.2-16.2 x 1010/unit, 0.6-16.4 x 1010/unit and 1.22-8.9 x 1011/unit respectively. The mean WBC count in PRP-PC (n = 10, BC-PC (n = 10 and apheresis-PC (n = 6 units was 4.05±0.48 x 107/unit, 2.08±0.39 x 107/unit and 4.8±0.8 x 106/unit and ranged from 3.4 -4.77 x 107/unit, 1.6-2.7 x 107/unit and 3.2 - 5.2 x 106/unit respectively. A total of 26 units were analyzed for pH changes. Out of these units, 10 each were PRP-PC and BC-PC and 6 units were apheresis-PC. Their mean pH was 6.7±0.26 (mean±SD and ranged from 6.5 - 7.0 and no difference was observed among all three types of platelet concentrate. Conclusion: PRP-PC and BC-PC units were comparable in terms of swirling, platelet count per unit and pH. As expected, we found WBC contamination to be less in BC-PC than PRP-PC units. Variation in volume was more in BC-PC than PRP-PC units and this suggests that further standardization is required for preparation of BC

High uncertainties affect black carbon (BC) emissions, and, despite its important impact on air pollution and climate, very few BC emissions evaluations are found in the literature. This paper presents a novel approach, based on airborne measurements across the Paris, France, plume, developed in order to evaluate BC and NOx emissions at the scale of a whole agglomeration. The methodology consists in integrating, for each transect, across the plume observed and simulated concentrations above background. This allows for several error sources (e.g., representativeness, chemistry, plume lateral dispersion) to be minimized in the model used. The procedure is applied with the CHIMERE chemistry-transport model to three inventories - the EMEP inventory and the so-called TNO and TNO-MP inventories - over the month of July 2009. Various systematic uncertainty sources both in the model (e.g., boundary layer height, vertical mixing, deposition) and in observations (e.g., BC nature) are discussed and quantified, notably through sensitivity tests. Large uncertainty values are determined in our results, which limits the usefulness of the method to rather strongly erroneous emission inventories. A statistically significant (but moderate) overestimation is obtained for the TNO BC emissions and the EMEP and TNO-MP NOx emissions, as well as for the BC / NOx emission ratio in TNO-MP. The benefit of the airborne approach is discussed through a comparison with the BC / NOx ratio at a ground site in Paris, which additionally suggests a spatially heterogeneous error in BC emissions over the agglomeration.

Characterization of the effects of cruise ship emissions on local air quality is scarce. Our objective was to investigate community level concentrations of fine particulate matter (PM 2.5), nitrogen dioxide (NO 2) and sulphur dioxide (SO 2) associated with cruise ships in James Bay, Victoria, British Columbia (BC), Canada. Data obtained over four years (2005-2008) at the nearest air quality network site located 3.5 km from the study area, a CALPUFF modeling exercise (2007), and continuous measurements taken in the James Bay community over a three-month period during the 2009 cruise ship season were examined. Concentrations of PM 2.5 and nitrogen oxide (NO) were elevated on weekends with ships present with winds from the direction of the terminal to the monitoring station. SO 2 displayed the greatest impact from the presence of cruise ships in the area. Network data showed peaks in hourly SO 2 when ships were in port during all years. The CALPUFF modeling analysis found predicted 24-hour SO 2 levels to exceed World Health Organization (WHO) guidelines of 20 μg m -3 for approximately 3% of 24-hour periods, with a maximum 24-hour concentration in the community of 41 μg m -3; however, the CALPUFF model underestimated concentrations when predicted and measured concentrations were compared at the network site. Continuous monitoring at the location in the community predicted to experience highest SO 2 concentrations measured a maximum 24-hour concentration of 122 μg m -3 and 16% of 24-hour periods were above the WHO standard. The 10-minute concentrations of SO 2 reached up to 599 μg m -3 and exceeded the WHO 10-minute SO 2 guideline (500 μg m -3) for 0.03% of 10-minute periods. No exceedences of BC Provincial or Canadian guidelines or standards were observed.

Strongylus vulgaris is an important strongyle nematode with high pathogenic potential infecting horses world-wide. Several decades of intensive anthelmintic use has virtually eliminated clinical disease caused by S. vulgaris, but has also caused high levels of anthelmintic resistance in equine small strongyle (cyathostomin) nematodes. Recommendations aimed at limiting the development of anthelmintic resistance by reducing treatment intensity raises a simultaneous demand for reliable and accurate diagnostic tools for detecting important parasitic pathogens. Presently, the only means available to differentiate among strongyle species in a faecal sample is by identifying individual L3 larvae following a two week coproculture procedure. The aim of the present study is to overcome this diagnostic obstacle by developing a fluorescence-based quantitative PCR assay capable of identifying S. vulgaris eggs in faecal samples from horses. Species-specific primers and a TaqMan probe were designed by alignment of published ribosomal DNA sequences of the second internal transcribed spacer of cyathostomin and Strongylus spp. nematodes. The assay was tested for specificity and optimized using genomic DNA extracted from identified male worms of Strongylus and cyathostomin species. In addition, eggs were collected from adult female worms and used to evaluate the quantitative potential of the assay. Statistically significant linear relationships were found between egg numbers and cycle of threshold (Ct) values. PCR results were unaffected by the presence of cyathostomin DNA in the sample and there was no indication of PCR inhibition by faecal sources. A field evaluation on faecal samples obtained from four Danish horse farms revealed a good agreement with the traditional larval culture (kappa-value=0.78), but with a significantly higher performance of the PCR assay. An association between Ct values and S. vulgaris larval counts was statistically significant. The present assay can

Graphical abstract: Schematic presentation of coagulation/flocculation of microalgal biomass using AMD. - Highlights: • AMDs containing high Fe"2"+/Al"3"+ improved the settling kinetics of microalgal biomass. • The highest k_2 value was 40 × 10"−"2 L mg"−"1 min"−"1 for C. vulgaris with AMD (1). • With AMD (2), k_2 was 4.0 × 10"−"2 L mg"−"1 min"−"1 for both C. vulgaris and S. obliquus. • The highest FE (93%) and CF (29) for C. vulgaris was achieved with AMD (1). • AMD (1) removed 99.80% of Fe"3"+ and 99.99% of Al"3"+ from the supernatant. - Abstract: Development of a low-cost harvesting technology could be an effective approach for making microalgal biofuel commercially feasible. The use of acid mine drainage (AMD) to coagulate/flocculate biomass is a cost-effective strategy for addressing this challenge. Here, settling kinetics, flocculation efficiency (FE), and concentration factor (CF) of two morphologically different microalgae species, Scenedesmus obliquus and Chlorella vulgaris, were investigated with respect to AMD dosage (5% and 10%) and medium pH (7 and 9). AMD was collected from two different sites, AMD (1) and AMD (2), and increasing its dosage to 10% improved the settling rate, FE, and CF of the floc. At 10% AMD (1) dosage and pH 9, the highest rate constants (k_2) for the second order equations were 6.65 × 10"−"2 and 40 × 10"−"2 L mg"−"1⋅min"−"1 for S. obliquus and C. vulgaris, respectively; at 10% AMD (2), k_2 values were 4.22 × 10"−"2 and 4.76 × 10"−"2 L mg"−"1 min"−"1, respectively. Similarly, FE/CF values were 89%/25 for S. obliquus and 93%/29 for C. vulgaris with 10% AMD (1); and 81%/17 and 79%/17, respectively, with 10% AMD (2). AMD effectively removed 99.80% of Fe"3"+, 99.99% of Al"3"+, 94% of Ca"2"+, 84% of Mg"2"+ and all of Na"+ and K"+ ions from the supernatant. The results of kinetics, EF, and CF measurements indicate that AMDs, naturally rich in iron and aluminum ions, could provide a feasible

Previous experiments examining the transcriptional profileof the anaerobe Desulfovibrio vulgaris demonstrated up-regulation of theFur regulon in response to various environmental stressors. To test theinvolvement of Fur in the growth response and transcriptional regulationof D. vulgaris, a targeted mutagenesis procedure was used for deletingthe fur gene. Growth of the resulting ?fur mutant (JW707) was notaffected by iron availability, but the mutant did exhibit increasedsensitivity to nitrite and osmotic stresses compared to the wild type.Transcriptional profiling of JW707 indicated that iron-bound Fur acts asa traditional repressor for ferrous iron uptake genes (feoAB) and othergenes containing a predicted Fur binding site within their promoter.Despite the apparent lack of siderophore biosynthesis genes within the D.vulgaris genome, a large 12-gene operon encoding orthologs to TonB andTolQR also appeared to be repressed by iron-bound Fur. While other genespredicted to be involved in iron homeostasis were unaffected by thepresence or absence of Fur, alternative expression patterns that could beinterpreted as repression or activation by iron-free Fur were observed.Both the physiological and transcriptional data implicate a globalregulatory role for Fur in the sulfate-reducing bacterium D.vulgaris.
Remote community electrification program - small wind integration in BC's offgrid communities

The paper presents the Remote Community Electrification (RCE) program and wind integration in BC's off grid communities. The program offers electric utility service to eligible remote communities in BC. Most of them are offered off-grid services although it is cheaper to connect a community to a grid. BC hydro serves some communities that are not connected to the main grid. Local diesel or small hydro-generating stations are used to serve remote communities. The renewable energy program target is to reach 50% of remote communities. The reason that wind is a small part of the renewables is that hydro and biomass are abundant in BC. Some other barriers include high installation costs, durability concerns, and lack of in-house technical expertise. Some small Wind initiatives that have been taken were relatively few and fairly small. It can be concluded that due to a poor wind resource and the relatively low cost of diesel, there is limited potential for wind in BC remote communities.

An attempt was made to control or eliminate Strongylus vulgaris from a closed group of three horses at pasture near Perth, Western Australia, by dosing with ivermectin on four occasions during the time of year when it was believed that environmental conditions would eliminate all the non-parasitic stages of that species. At necropsy, five months after the last dose of anthelmintic and after continually grazing the same pastures, no S vulgaris or arterial lesions were found in those horses and S edentatus, Draschia megastoma and Habronema species were also almost completely eliminated.

Psoriasis vulgaris is an autoimmune chronic inflammatory skin disease, but its association with other typical autoimmune disease such as systemic lupus erythematosus has only occasionally been reported. We presented a 25-year-old female who developed systemic lupus erythematosus associated with psoriasis vulgaris. Her conditions were in good control after she got administration of prednisolone (5 mg/day) and Tripterygium Wilfordii Hook (20 mg/day). It is necessary to integrate past history and physical examination to diagnose coincident SLE and psoriasis, and combined treatment with prednisolone and Tripterygium Wilfordii Hook proves effective.

Acne vulgaris is the most common skin disease worldwide; yet, current treatment options, although effective, are associated with unwanted side effects, chronicity, relapses and recurrences. The adequate control of the four pathogenic mechanisms, involved in the appearance of acne lesions, is paramount to treatment success. The authors discuss and evaluate the pathogenic pathways related to the mechanisms of action of novel molecules, which are currently under investigation for the treatment of acne vulgaris. The manuscript is based on comprehensive searches made through PubMed, GoogleScholar and ClinicalTrial.gov, using different combination of key words, which include acne vulgaris, pathogenesis, treatment, sebogenesis and Propionibacterium acnes. In the near future, more effective treatments with fewer side effects are expected. The use of topical antiandrogens, acetylcholine inhibitors and PPAR modulators seem to be promising options for controlling sebum production. Retinoic acid metabolism-blocking agents and IL-1α inhibitors have the potential to become legitimate alternative options to retinoid therapy in the management of infundibular dyskeratosis. Indeed, the authors believe that there will likely be a decline in the use of antibiotics for controlling P. acnes colonization and targeting the inflammation cascade.

The aim of this study was to investigate the oxidation products of p-cymene-2,3-diol, a major antioxidative constituent of thyme (Thymus vulgaris L.). Although a dimeric form of p-cymene-2,3-diol and some derivative substances exhibiting valuable food technological and health-promoting properties have been reported in earlier publications, no obvious correlation has been shown between these substances. A modified HPLC-ESI-MS method made it possible to prove that two dimers, 3,4,3',4'-tetrahydroxy-5,5'-diisopropyl-2,2'-dimethylbiphenyl (1) and the newly identified 3',4'-dihydroxy-5,5'-diisopropyl-2,2'-dimethylbiphenyl-3,4-dione (2), are oxidation products of p-cymene-2,3-diol. 2 was characterized by the fragmentation pattern determined by multiple mass spectrometry, (1)H NMR, (13)C NMR, H-H COSY, HSQC, and HMBC. Both biphenyls were also quantitated in freeze-dried thyme as well as in a food matrix spiked with thyme extract. Model experiments using raw and cooked minced pork meat as matrix and sodium nitrite as oxidizing and reduction agent with and without ascorbic acid as protective reagent showed the correlation between food processing and dimer generation.

Ferti-irrigation response of 5, 10, 25, 50, 75, and 100 % concentrations of the sugar mill effluent (SME) on French bean (Phaseolus vulgaris L., cv. Annapurna) in the rainy and summer seasons was investigated. The fertigant concentrations produced significant (P potassium (K(+)), calcium (Ca(2+)), magnesium (Mg(2+)), total Kjeldahl nitrogen (TKN), phosphate (PO4 (3-)), sulfate (SO4 (2-)), ferrous (Fe(2+)), cadmium (Cd), chromium (Cr), copper (Cu), manganese (Mn), and zinc (Zn), in both seasons. The contents of Cr, Cu, Mn, and Zn except Cd were found to be below the maximum levels permitted for soils in India. The agronomic performance of P. vulgaris was gradually increased at lower concentrations, i.e., from 5 to 25 %, and decreased at higher concentrations, i.e., from 50 to 100 %, of the SME in both seasons when compared to controls. The accumulations of heavy metals were increased in the soil and P. vulgaris from 5 to 100 % concentrations of the SME in both seasons. The contents of Cu, Mn, and Zn except Cd and Cr were noted under the permissible limit of Food and Agriculture Organization (FAO)/World Health Organization (WHO) standards. Most contents of biochemical components like crude proteins, crude fiber, and total carbohydrates were found with 25 % concentration of the SME in both seasons. The contamination factor (Cf) of various metals was in the order of Cd > Cr > Zn > Mn > Cu for soil and Mn > Zn > Cu > Cr > Cd for P. vulgaris in both seasons after fertigation with SME. Therefore, the SME can be used to improve the soil fertility and yield of P. vulgaris after appropriate dilution.

Methods: The shade dried leaves powder was extracted with methanol by using Soxhlet extractor. Methanol crude extracts of T. vulgaris and the derived fractions of hexane, chloroform, ethyl acetate and butanol were obtained. Results: Qualitative analyses of various organic crude extracts of T. vulgaris by using GC-MS showed that there were different types of high and low molecular weight compounds. Most of the isolated and identified compounds by GC-MS in the crude extracts are basically biologically important. Further, the T. vulgaris leaf possessed certain characteristics that can be ascribed to cultivation on a domestic plantation. The crude extracts were prepared from the powder leaves of T. vulgaris for respective compounds can be chosen on the basis of above GC-MS analysis. Conclusions: All the major compounds were identified and characterized by spectroscopic method in different organic crude extracts of T. vulgaris are biologically active molecules. Thus the identification of a good number of compounds in various crude extracts of T. vulgaris might have some ecological role.

Abstract Improving the charge carrier mobility of solution‐processable organic semiconductors is critical for the development of advanced organic thin‐film transistors and their application in the emerging sector of printed electronics. Here, a simple method is reported for enhancing the hole mobility in a wide range of organic semiconductors, including small‐molecules, polymers, and small‐molecule:polymer blends, with the latter systems exhibiting the highest mobility. The method is simple and relies on admixing of the molecular Lewis acid B(C6F5)3 in the semiconductor formulation prior to solution deposition. Two prototypical semiconductors where B(C6F5)3 is shown to have a remarkable impact are the blends of 2,8‐difluoro‐5,11‐bis(triethylsilylethynyl)anthradithiophene:poly(triarylamine) (diF‐TESADT:PTAA) and 2,7‐dioctyl[1]‐benzothieno[3,2‐b][1]benzothiophene:poly(indacenodithiophene‐co‐benzothiadiazole) (C8‐BTBT:C16‐IDTBT), for which hole mobilities of 8 and 11 cm2 V−1 s−1, respectively, are obtained. Doping of the 6,13‐bis(triisopropylsilylethynyl)pentacene:PTAA blend with B(C6F5)3 is also shown to increase the maximum hole mobility to 3.7 cm2 V−1 s−1. Analysis of the single and multicomponent materials reveals that B(C6F5)3 plays a dual role, first acting as an efficient p‐dopant, and secondly as a microstructure modifier. Semiconductors that undergo simultaneous p‐doping and dopant‐induced long‐range crystallization are found to consistently outperform transistors based on the pristine materials. Our work underscores Lewis acid doping as a generic strategy towards high performance printed organic microelectronics. PMID:29375962

The aim of this study was to investigate the prevalence of thyroid function abnormalities and thyroid autoimmunity in patients with pemphigus vulgaris (PV and to determine the association between thyroid disorders and clinical involvement and systemic corticosteroid treatment in patients with PV. Methods. The study consisted of eighty patients with PV and eighty healthy individuals. Thyroid functions (fT3, fT4, and TSH and thyroid autoimmunity (anti-thyroid peroxidase (anti-TPO, and anti-thyroglobulin (anti-Tg antibodies were investigated in both groups. Primary thyroid disease (PTD was diagnosed with one or more of the following diagnostic criteria: (i positive antithyroid antibodies, (ii primary thyroid function abnormalities. Results. Significant changes in the serum thyroid profile were found in 16% (13/80 of the PV group and 5% (4/80 of the control group. Positive titers of antithyroid antibodies (anti-TPO and anti-Tg were observed in 7 patients (9% with PV and one in the control group (1,2%. Hashimoto thyroiditis was diagnosed in 9% of PV patients and it was found to be more prevalent in the mucosal form of PV. PTD was found in 13 of (%16 PV patients which was significantly high compared to controls. PTD was not found to be associated with systemic corticosteroid use. Free T3 levels were significantly lower in PV group compared to the control group and free T4 levels were significantly higher in PV group compared to the controls. Conclusions. PV may exist together with autoimmune thyroid diseases especially Hashimoto thyroiditis and primer thyroid diseases. Laboratory work-up for thyroid function tests and thyroid autoantibodies should be performed to determine underlying thyroid diseases in patients with PV.

In this study, in vitro antidermatophytic activity against Trichophyton mentagrophytes, Trichophyton rubrum, Microsporum canis, and Microsporum gypseum was studied by disk diffusion test and assessment of minimum inhibitory concentration (MIC) using CLSI broth macrodilution method (M38-A2). Moreover, antileishmanial and cytotoxicity activity of B. vulgaris and berberine against promastigotes of Leishmania major and Leishmania tropica were evaluated by colorimetric MTT assay. The findings indicated that the various extracts of B. vulgaris particularly berberine showed high potential antidermatophytic against pathogenic dermatophytes tested with MIC values varying from 0.125 to >4 mg/mL. The results revealed that B. vulgaris extracts as well as berberine were effective in inhibiting L. major and L. tropica promastigotes growth in a dose-dependent manner with IC50 (50% inhibitory concentration) values varying from 2.1 to 26.6 μ g/mL. Moreover, it could be observed that berberine as compared with B. vulgaris exhibited more cytotoxicity against murine macrophages with CC50 (cytotoxicity concentration for 50% of cells) values varying from 27.3 to 362.6 μ g/mL. Results of this investigation were the first step in the search for new antidermatophytic and antileishmanial drugs. However, further works are required to evaluate exact effect of these extracts in animal models as well as volunteer human subjects.

At necropsy of 49 Thoroughbreds from farms with generally good parasite control programs in central Kentucky, examination was specifically made for presence of Strongylus vulgaris in all of the horses and of Parascaris equorum in 21 of them. None of the deaths of the horses was caused by infections of internal parasites. Visceral arteries were examined for specimens of S vulgaris and lesions related to migrating stages of this parasite. Contents of the small intestines were examined for P equorum. Specimens of S vulgaris were recovered from 19 (39%) horses, and arterial lesions were observed in 24 (49%) of them. Parascaris equorum was found in 9 (43%) horses. Both parasites were found to persist in generally low numbers on farms in spite of their parasite control programs applied in recent years.

Expert panel discussions were held in 2013 and 2014 among a group of scientists and clinicians from the Omani and United Arab Emirate Dermatology Societies to ascertain the current optimal management of acne vulgaris, identify clinically relevant end-points and construct suitable methodology for future clinical trial designs. This article reviews the discussions of these sessions and recent literature on this topic.

Radiolabeled D-[1- 3 H]glucose was fed by imbibition under sterile conditions to bean (Phaseolus vulgaris L.) seeds. After 72 and 96 hours of feeding, the 3 H was located in uronic acid and pentose residues as well as hexose residues of cell wall polysaccharides in growing hypocotyl and root. Free myo-inositol present in cotyledons, hypocotyl, and root also contained 3 H, showing that de novo synthesis of myo-inositol from [1- 3 H]glucose did occur during the first 72 hours of germination. More than 90% of the labeled, free myo-inositol was present in the cotyledons. The 3 H percentage in trifluoroacetic acid-soluble arabinaose residues of cell wall polysaccharides from 72-hour-old bean hypocotyls was only half of their mole percentage. On the other hand, 3 H percentages in hexose residues were higher than their mole percentages. The results suggest that myo-inositol is synthesized from reserve sugars during the very early stages of germination, and that the newly synthesized myo-inositol, as well as that stored in cotyledons, can be used for the construction of new hypocotyl and root cell wall polysaccharides after conversion into uronic acids and pentoses via the myo-inositol oxidation pathway

In order for renewable energy to play a dominant role in the global electricity supply mix, emerging renewable energy technologies - such as wave, tidal, enhanced geothermal, and 3rd generation photovoltaic technologies - must prove their technical merits and achieve cost parity with conventional sources of supply. BC Hydro, a government-owned electric utility, launched an Alternative and Emerging Energy Strategy that describes its role as an enabler of technology innovation. This paper describes BC Hydro's goal, objectives and actions to accelerate the commercialization that will yield a diversity of supply options and a growing, local clean-tech cluster.

CrBC and CrBCN coatings with low and high B contents were deposited on 316L steel and Si wafers using an unbalanced magnetron sputtering system. Mechanical properties including hardness (H), elastic modulus (E) and fracture toughness (KIc) as well as residual stresses (σ) were quantified. A clear correlation between structural, mechanical and tribological properties of coatings was found. In particular, structural analyses indicated that N incorporation in CrBC coatings with high B content caused a significant structural evolution of the nanocomposite structure (crystalline grains embedded into an amorphous matrix) from nc-CrB2/(a-CrBx, a-BCx) to nc-CrN/(a-BCx, a-BN). As a result, the hardness of CrBC coating with high B content decreased from 23.4 to 16.3 GPa but the fracture toughness was enhanced. Consequently, less cracks initiated on CrBCN coatings during tribological tests, which combined with the shielding effect of a-BN on wear debris, led to a low friction coefficient and wear rate.
Tinea manuum misdiagnosed as psoriasis vulgaris: A case of tinea incognito

Full Text Available Tinea incognito is a dermatophyte infection with altered clinical appearance which is usually caused by the use of immunosuppressive agents such as topical corticosteroids. Hereby, we present a 59-year-old Caucasian male patient with tinea manuum on the dorsum of his left hand. The lesion was formerly misdiagnosed as psoriasis vulgaris and treated with topical corticosteroids. However, the symptoms were worsened. Moreover, new papules and pustules appeared within the lesion. The past medical history was remarkable for psoriasis vulgaris and he had an erythematous and squamous plaque on his lower back resembling psoriasis vulgaris. In order to reach a definitive diagnosis, the skin lesion on the dorsum of the patient’s left hand was examined by light microscopy after the application of 10% potassium hydroxide solution. Detection of septate hyphae confirmed dermatophytosis. The lesion was completely healed with oral terbinafine 250 mg daily for four weeks. Dermatophyte infections in early stages may be misdiagnosed as psoriasis vulgaris and thus, prolonged use of corticosteroids can lead to tinea incognito. Therefore, cutaneous lesions unresponsive to topical corticosteroid treatment should be evaluated with microscopic examination and fungal culture to confirm a suspected dermatophyte infection. Past medical history can provide useful information but a complete dermatological examination should be performed before the final diagnosis is made.

Strongylus vulgaris has become a rare parasite in Germany during the past 50 years due to the practice of frequent prophylactic anthelmintic therapy. To date, the emerging development of resistance in Cyathostominae and Parascaris spp. to numerous equine anthelmintics has changed deworming management and the frequency of anthelmintic usage. In this regard, reliable detection of parasitic infections, especially of the highly pathogenic S. vulgaris is essential. In the current study, two diagnostic methods for the detection of infections with S. vulgaris were compared and information on the occurrence of this parasite in German horses was gained. For this purpose, faecal samples of 501 horses were screened for S. vulgaris with real-time PCR and an additional larval culture was performed in samples of 278 horses. A subset of 26 horses underwent multiple follow-up examinations with both methods in order to evaluate both the persistence of S. vulgaris infections and the reproducibility of each diagnostic method. The real-time PCR revealed S. vulgaris-DNA in ten of 501 investigated equine samples (1.9%). The larval culture demonstrated larvae of S. vulgaris in three of the 278 samples (1.1%). A direct comparison of the two methods was possible in 321 samples including 43 follow-up examinations with the result of 11 S. vulgaris-positive samples by real-time PCR and 4 S. vulgaris-positive samples by larval culture. The McNemar's test (p-value = 0.016) revealed a significant difference and the kappa values (0.525) showed a moderate agreement between real-time PCR and larval culture. The real-time PCR detected a significantly higher proportion of positives of S. vulgaris compared to larval culture and should thus be considered as a routine diagnostic method for the detection of S. vulgaris in equine samples.
The variability in the relationship between black carbon and carbon monoxide over the eastern coast of China: BC aging during transport

Full Text Available East Asia is a densely populated region with a myriad of primary emissions of pollutants such as black carbon (BC and carbon monoxide (CO. To characterize primary emissions over the eastern coast of China, a series of field campaigns were conducted in 2011, including measurements from a ship cruise, island, and coastal receptor sites. The relationship between BC and CO is presented here for the first ship cruise (C1, the second ship cruise (C2, an island site (Changdao Island, CD, and a coastal site (Wenling, WL. The average BC mass concentrations were 2.43, 2.73, 1.09, 0.94, and 0.77 µg m−3 for CD, WL, C1-YS (Yellow Sea, C1-ES (East China Sea, and C2-ES, respectively. For those locations, the average CO mixing ratios were 0.55, 0.48, 0.31, 0.36, and 0.27 ppm. The high loadings of both BC and CO imply severe anthropogenic pollution over the eastern coast of China. Additionally, the linear correlation between BC and CO was regressed for each location. The slopes, i.e., the ratios of ΔBC to ΔCO derived from their relationship, correlated well with the ratios of diesel consumption to gasoline consumption in each province/city, which reveals vehicular emission to be the common source for BC and CO and that there are distinct fuel structures between North and South China. The ΔBC/ΔCO values at coastal sites (Changdao Island and Wenling were much higher than those over the Yellow Sea and East China Sea, and the correlation coefficients also showed a decreasing trend from the coast to the sea. Therefore, the quantity of ΔBC/ΔCO and the correlation coefficients are possible indicators for the aging and removal of BC.

Monosodium glutamate wastewater (MSGW) is a potential medium for microbial cultivation because of containing abundant organic nutrient. This paper seeks to evaluate the feasibility of growing Chlorella vulgaris with MSGW and assess the influence of MSGW concentration on the biomass productivity and biochemical compositions. The MSGW diluted in different concentrations was prepared for microalga cultivation. C. vulgaris growth was greatly promoted with MSGW compared with the inorganic BG11 medium. C. vulgaris obtained the maximum biomass concentration (1.02 g/L) and biomass productivity (61.47 mg/Ld) with 100-time diluted MSGW. The harvested biomass was rich in protein (36.01-50.64%) and low in lipid (13.47-25.4%) and carbohydrate (8.94-20.1%). The protein nutritional quality and unsaturated fatty acids content of algal increased significantly with diluted MSGW. These results indicated that the MSGW is a feasible alternative for mass cultivation of C. vulgaris. Copyright © 2013 Elsevier Ltd. All rights reserved.

Highlights: • Extended incubation time to 16 days allowed significant FeS crystallization. • A weakly acidic pH greatly enhanced particle growth of mackinawite. • Microbial metabolism of different donors systematically altered the ambient pH. • Greater sulfide accumulation stimulated mackinawite transformation to greigite. - Abstract: Sulfate-reducing bacteria (SRB) can produce iron sulfide (FeS) solids with mineralogical characteristics that may be beneficial for a variety of biogeochemical applications, such as long-term immobilization of uranium. In this study, the growth and metabolism of Desulfovibrio vulgaris, one of the best-studied SRB species, were comprehensively monitored in batch studies, and the biogenic FeS solids were characterized by X-ray diffraction. Controlling the pH by varying the initial pH, the iron-to-sulfate ratio, or the electron donor – affected the growth of D. vulgaris and strongly influenced the formation and growth of FeS solids. In particular, lower pH (from initial conditions or a decrease caused by less sulfate reduction, FeS precipitation, or using pyruvate as the electron donor) produced larger-sized mackinawite (Fe 1+x S). Greater accumulation of free sulfide, from more sulfate reduction by D. vulgaris, also led to larger-sized mackinawite and particularly stimulated mackinawite transformation to greigite (Fe 3 S 4 ) when the free sulfide concentration was 29.3 mM. Furthermore, sufficient free Fe 2+ led to the additional formation of vivianite [Fe 3 (PO 4 ) 2 ·8(H 2 O)]. Thus, microbially relevant conditions (initial pH, choice of electron donor, and excess or deficiency of sulfide) are tools to generate biogenic FeS solids of different characteristics

Vaginal involvement in pemphigus vulgaris has previously been described. In all those cases a pelvic examination was needed to explore the lesions. We describe a patient with pemphigus vulgaris who had pemphigus erosions on a prolapsed uterus (i.e., on the everted surface of vagina). The patient had widespread lesions of pemphigus in other mucosal and cutaneous sites. Biopsy, antibodies against desmoglein 1 and 3, and direct and indirect immunofluorescence were confirming. The erosions on the prolapsed uterus were resistant to treatment; other mucosal and cutaneous lesions responded rapidly to prednisolone and azathioprine. After lowering the dose of prednisolone the patient was referred to a gynecologist for a vaginal hysterectomy. This case was unique because her vaginal lesions could be easily examined and followed.

It is known that the capacity region of a two user physically degraded discrete memoryless (DM) broadcastchannel (BC) is not enlarged by feedback. An identical result holds true for a physically degraded Gaussian BC,established later using a variant of the Entropy Power Inequality (EPI). In this paper, we extend the latter resultto a physically degraded Gaussian Vector BC (PD-GVBC). However, the extension is not EPI based, but employs arecent result on the factorization of concave envelopes. ...

A 1.1 kb cDNA clone (hp4F1) encoding the human vimentin gene was identified in a human library by screening with 4F1, a hamster vimentin cDNA. BcII (TGATCA) recognizes a two allele polymorphism: bands A1 at 8.1 kb, and A2 at 3.6 kb. The allele frequency was determined in 47 unrelated Caucasian individuals. The RFLP was mapped to chromosome 10pter-10q23 using somatic cell hybrids and to 10p13 by in situ hybridization. Co-dominant segregation was observed in 2 informative families.
Variation in the Breeding System of Prunella vulgaris L.

Qu, Luping; Widrlechner, Mark P

Prunella vulgaris (Lamiaceae), commonly known as selfheal, is a perennial herb with a long history of use in traditional medicine. Recent studies have found that P. vulgaris possesses anti-inflammatory, antiviral, and antibacterial properties, and it is likely that this will lead to increased commercial demand for this species. To date, research publications on P. vulgaris cultivation and genetics are scarce. Using accessions originally collected from different geographical regions, we investigated the breeding system of this species by observing variation in floral morphology, time of pollen release, and selfed-seed set in bagged flowers and isolated plants. Two types of floral morphology, one with exerted styles, extending past open corollas when viewed from above, and the other with shorter, inserted styles, were found among 30 accessions. Two accessions originally collected from Asia uniformly displayed exerted styles, and 27 accessions had inserted styles. One accession from Oregon displayed variation in this trait among individual plants. Microscopic observation of seven accessions, including ones with both exerted and inserted styles, revealed that they all release pollen to some degree before the flowers open. Using bagged flowers, we found that selfed-seed set varied widely among eight accessions, ranging from 6% to 94%. However, bagging may underestimate seed set for some accessions. The two accessions with the lowest rates when using bagged flowers increased in seed set by 350% and 158%, respectively, when we evaluated single, unbagged plants in isolation cages. The accession with 6% selfed-seed set when bagged also had exerted styles. These findings suggest that mating systems in P. vulgaris may be in the process of evolutionary change and that understanding breeding-system variation should be useful in developing efficient seed-regeneration protocols and breeding and selection strategies for this species.

Cosmetic camouflage is important for patients with vitiligo vulgaris. However, few studies have investigated its benefit for vitiligo patients. To analyze the psychological effects on patients with vitiligo vulgaris by camouflage lessons performed in vitiligo clinics in Kyoto University Hospital and Fukui Red Cross Hospital, Dermatological Life Quality Index (DLQI) questionnaires were collected before and 1 month after camouflage lessons. Patients with vitiligo vulgaris, who visited our clinics in 2008 and had never experienced camouflage, were enrolled in this study. They took camouflage lessons and continued subsequent self-camouflage for 1 month. Control patients took no lessons and no camouflage. Camouflage improved the scores of DLQI when compared with those without camouflage (P = 0.005). Camouflage improved DLQI scores from 5.90 to 4.48. In DLQI subcategories, camouflage lessons improved a subcategory of "symptoms and feelings" (P = 0.0037). These data supported the idea that camouflage for patients with vitiligo not only covers the white patches but also improves their quality of life.

The investigated northwest German mire site at Totes Moor is densely covered with subfossil pine stumps (Pinus sylvestris L.) from the fen-bog transition. This facilitates the spatio-temporal reconstruction of mire development, which is based on 212 in situ tree stumps in the case study presented here. Six dendrochronologically dated site chronologies together cover 2345 years between 6703 and 3403 BC. The gaps in between are 6 to 550 years long. Additionally, a floating chronology of 309 years, containing 30 trees, was radiocarbon-dated to the beginning of the 7th millennium cal BC. Peat-stratigraphical survey was carried out additionally, and elevations a.s.l. were determined at several locations. Tree dying-off phases, which indicate water level rise at the site, mostly in context of the local fen-bog transition, are evident for ca. 6600-6450, ca. 6350-5750, ca. 5300-4900, ca. 4700-4550, ca. 3900-3850, ca. 3700-3600, ca. 3500-3450 and ca. 3400 BC. The spatial distribution of the dated in situ trees illustrates the phase-wise expansion of raised bog over fen peat at the site. The documented bog expansion pulses likely correspond to climatic wet sifts.

The lifetime of the $B_c^+$ meson is measured using semileptonic decays having a $J/\\psi$ meson and a muon in the final state. The data, corresponding to an integrated luminosity of $2\\mathrm{~fb^{-1}}$, are collected by the LHCb detector in $pp$ collisions at a centre-of-mass energy of $8\\,\\mathrm{TeV}$. The measured lifetime is $$\\tau = 509 \\pm 8 \\pm 12 \\mathrm{~fs},$$ where the first uncertainty is statistical and the second is systematic.

Full Text Available Alternative culture media have been evaluated for the cultivation of microalgae, among them are, industrial and agriculture wastewaters, that make residue recycling possible by bioconverting it into a rich, nourishing biomass that can be used as a feeding complement in aquaculture and in diverse areas. The objective of this research is to determine the lipid, fatty acid profile and carotenoid produced by the microalgae Chlorella vulgaris cultivated in a hydroponic wastewater, with different dilutions. The results showed that lipid contents did not present significant differences. Fatty acids were predominantly 16:0, 18:0, 18:1 and 18:3n-6. For total carotenoids, the dilution of hydroponic wastewater did not stimulate the production of these pigments. From this study, it was determined that, the use of hydroponic wastewater as an alternative culture medium for the cultivation of Chlorella vulgaris generates good perspectives for lipid, fatty acid and carotenoid production.Medios de cultivo alternativos vienen siendo evaluados para el cultivo de microalgas, entre ellos, están los afluentes industriales y agrícolas, que posibilitan la reciclaje del residuo, bioconvirtiéndose en una biomasa enriquecida bajo el punto de vista nutricional, que puede ser utilizada como complemento alimenticio, para la acuacultura y en varias otras áreas de actuación. El presente trabajo tuvo como objetivo determinar los contenidos de lípidos, composición de ácidos grasos y carotenoides producidos por la microalga Chlorella vulgaris cultivada en solución hidropónica residual, con diferentes diluciones. Los resultados de los contenidos de lípidos totales no presentaron diferencia significativa. Los ácidos grasos predominantes fueron los 16:0, 18:0, 18:1 e 18:3n-6. Para los carotenoides totales, la dilución de la solución hidropónica residual no estimuló la producción de estos pigmentos por la microalga. La utilización de la solución hidrop
Genetic concepts in Greek literature from the eighth to the fourth century B.C.

A review of the concepts of genetics found in epic, historical and dramatic ancient Greek writings from the eighth to the fourth centuries B.C., is presented. The derived data suggest that the development of genetical concepts and ideas started with the praise of the heroes' divine or noble origin in Homer's epic poems (eighth century B.C.). It continued in the tracing of the descent and vicissitudes of the families of the Greek gods and the common ancestry of the Greek tribes as described in Hesiod's genealogical poems (around 700 B.C.), in the statement of descent and dual parenthood of leaders and kings in the books of Herodotus and Xenophon (fifth and fourth centuries B.C.), and in the concern about the lineage of the tragic figures in Greek drama (fifth century B.C.). The genetical concepts expressed in these writings most probably reflected popular notions of that time. They must, therefore, have been the basis of the perceptions and theories on heredity and procreation expressed by the ancient physicians and philosophers in the fifth and fourth centuries B.C., which in turn influenced the development of genetics for many centuries.

Black carbon (BC), and its vertical distribution, affects the climate. Global measurements of BC vertical profiles are lacking to support climate change research. To fill this gap, a campaign was conducted over three Italian basin valleys, Terni Valley (Appennines), Po Valley and Passiria Valley (Alps), to characterize the impact of BC on the radiative budget under similar orographic conditions. 120 vertical profiles were measured in winter 2010. The BC vertical profiles, together with aerosol size distribution, aerosol chemistry and meteorological parameters, have been determined using a tethered balloon-based platform equipped with: a micro-Aethalometer AE51 (Magee Scientific), a 1.107 Grimm OPC (0.25-32 μm, 31 size classes), a cascade impactor (Siuotas SKC), and a meteorological station (LSI-Lastem). The aerosol chemical composition was determined from collected PM2.5 samples. The aerosol absorption along the vertical profiles was measured and optical properties calculated using the Mie theory applied to the aerosol size distribution. The aerosol optical properties were validated with AERONET data and then used as inputs to the radiative transfer model libRadtran. Vertical profiles of the aerosol direct radiative effect, the related atmospheric absorption and the heating rate were calculated. Vertical profile measurements revealed some common behaviors over the studied basin valleys. From below the mixing height to above it, a marked concentration drop was found for both BC (from -48.4±5.3% up to -69.1±5.5%) and aerosol number concentration (from -23.9±4.3% up to -46.5±7.3%). These features reflected on the optical properties of the aerosol. Absorption and scattering coefficients decreased from below the MH to above it (babs from -47.6±2.5% up to -71.3±3.0% and bsca from -23.5±0.8% up to -61.2±3.1%, respectively). Consequently, the Single Scattering Albedo increased above the MH (from +4.9±2.2% to +7.4±1.0%). The highest aerosol absorption was
Performance of conventional pcr for screening for strongylus vulgaris on horse farms

DEFF Research Database (Denmark)

Nielsen, Marianne K.; Wøhlk, Chamilla B.M.; Petersen, Stig L.

Strongyle parasites are ubiquitous in grazing horses. Of these, the bloodworm Strongylus vulgaris is regarded most pathogenic. Increasing levels of anthelmintic resistance in strongyle parasites has lead to recommendations of decreased treatment intensities, and there is now a pronounced need...... for reliable tools for detection of parasite burdens in general and S. vulgaris in particular. The only method currently available is the larval culture, which is laborious and time-consuming, so veterinary practitioners most often pool samples from several horses together in one culture to save time....... This raises doubts about the reliability of the method. Recently, molecular tools have been developed to detect S. vulgaris in fecal samples. The aim of this study was to compare the performance of a conventional polymerase chain reaction (PCR) assay with the traditional larval culture and furthermore test...

Chlorella vulgaris, is a kind of single-celled green algae, which could serve as a potential source of food and energy because of its photosynthetic efficiency. In our study, a pathogenic organism targeting C. vulgaris was discovered. The algae-lytic activity relates to a fraction from lysates of infected C. vulgaris that was blocked upon filtration through a 3 µm filter. 18S rRNA gene sequence analysis revealed that it shared 99.0% homology with the protist Pseudobodo tremulans. Scanning electron microscope analysis showed that Pseudobodo sp. KD51 cells were approximately 4–5 µm long, biflagellate with an anterior collar around the anterior part of the cell in unstressed feeding cells. Besides the initial host, Pseudobodo sp. KD51 could also kill other algae, indicating its relatively wide predatory spectrum. Heat stability, pH and salinity tolerance experiments were conducted to understand their effects on its predatory activities, and the results showed that Pseudobodo sp. KD51 was heat-sensitive, and pH and salinity tolerant. PMID:24599263

Full Text Available Chlorella vulgaris, is a kind of single-celled green algae, which could serve as a potential source of food and energy because of its photosynthetic efficiency. In our study, a pathogenic organism targeting C. vulgaris was discovered. The algae-lytic activity relates to a fraction from lysates of infected C. vulgaris that was blocked upon filtration through a 3 µm filter. 18S rRNA gene sequence analysis revealed that it shared 99.0% homology with the protist Pseudobodo tremulans. Scanning electron microscope analysis showed that Pseudobodo sp. KD51 cells were approximately 4-5 µm long, biflagellate with an anterior collar around the anterior part of the cell in unstressed feeding cells. Besides the initial host, Pseudobodo sp. KD51 could also kill other algae, indicating its relatively wide predatory spectrum. Heat stability, pH and salinity tolerance experiments were conducted to understand their effects on its predatory activities, and the results showed that Pseudobodo sp. KD51 was heat-sensitive, and pH and salinity tolerant.

Cattanach, D. [BC Hydro, Burnaby, BC (Canada). Emergency Preparedness Security and Public Safety

2009-07-01

This presentation reviewed public safety and historical practices at British Columbia (BC) Hydro. Historically, visitors were guided to safe locations at their facilities by visitor centres and public use management areas. Fences and booms were used to protect visitors from the more dangerous areas around the facility. This presentation also described the features of the safety management plans that BC Hydro has in place for each of its 41 facilities. The safety management plans are approved by the plant managers; they have common controls such as fences and signs; and there are excellent maps defining the danger areas. New risks that were identified were also presented. The next steps for BC Hydro include test driving the draft Canadian Dam Association guidelines for the Aberfeldie Dam; a new powerhouse to reduce overtopping of the dam during the spring; and continuing with public safety hazards and controls such as bow-ties. figs.

Baigent, Stephen

2013-01-01

We investigate the existence, uniqueness and Gaussian curvature of the invariant carrying simplices of 3 species autonomous totally competitive Lotka–Volterra systems. Explicit examples are given where the carrying simplex is convex or concave, but also where the curvature is not single-signed. Our method monitors the curvature of an evolving surface that converges uniformly to the carrying simplex, and generally relies on establishing that the Gaussian image of the evolving surface is confined to an invariant cone. We also discuss the relationship between the curvature of the carrying simplex near an interior fixed point and its Split Lyapunov stability. Finally we comment on extensions to general Lotka–Volterra systems that are not competitive. (paper)

The inducibility of the glucosinolate resistance mechanism is an energy-saving strategy for plants, but whether induction would still be triggered by glucosinolate-tolerant Plutella xylostella (diamondback moth, DBM) after a plant had evolved a new resistance mechanism (e.g., saponins in Barbara vulgaris) was unknown. In B. vulgaris, aromatic glucosinolates derived from homo-phenylalanine are the dominant glucosinolates, but their biosynthesis pathway was unclear. In this study, we used G-type (pest-resistant) and P-type (pest-susceptible) B. vulgaris to compare glucosinolate levels and the expression profiles of their biosynthesis genes before and after infestation by DBM larvae. Two different stereoisomers of hydroxylated aromatic glucosinolates are dominant in G- and P-type B. vulgaris, respectively, and are induced by DBM. The transcripts of genes in the glucosinolate biosynthesis pathway and their corresponding transcription factors were identified from an Illumina dataset of G- and P-type B. vulgaris. Many genes involved or potentially involved in glucosinolate biosynthesis were induced in both plant types. The expression patterns of six DBM induced genes were validated by quantitative PCR (qPCR), while six long-fragment genes were validated by molecular cloning. The core structure biosynthetic genes showed high sequence similarities between the two genotypes. In contrast, the sequence identity of two apparent side chain modification genes, the SHO gene in the G-type and the RHO in P-type plants, showed only 77.50% identity in coding DNA sequences and 65.48% identity in deduced amino acid sequences. The homology to GS-OH in Arabidopsis, DBM induction of the transcript and a series of qPCR and glucosinolate analyses of G-type, P-type and F1 plants indicated that these genes control the production of S and R isomers of 2-hydroxy-2-phenylethyl glucosinolate. These glucosinolates were significantly induced by P. xylostella larvae in both the susceptiple P

Phytochelatins, with the general structure of (γ-Glu-Cys)n-Gly (n = 2-11), are usually recognized as being strongly induced by metals in microalgae and play an important role in the detoxification of heavy metals in environment. However, there have been few studies on metallothionein (MT) synthesis in Chlorella vulgaris (C. vulgaris) exposed to heavy metals. The present study describes the growth inhibition of C. vulgaris exposed to different concentrations of cadmium and zinc, and the induction of metal-binding MT-like proteins in the cells. The amounts of metal-binding proteins, induced in the alga exposed to different concentrations of Cd and Zn, were analyzed with a size-exclusion HPLC coupled to ICP-MS. After being purified with a gel filtration column (Sephadex G-75, 3.5 cm x 80 cm) and a desalting column (G-25, 1.5 cm x 30 cm), the isoforms and sub-isoforms of Zn-binding protein were characterized by a reverse phase-HPLC coupled to electrospray ionization and a triple quadrupole mass spectrometer (HPLC-ESI-MS/MS). In addition, the ultraviolet spectra of purified Zn-binding proteins were analyzed in media with different pH values. The results showed that the significant inhibitory effects (at p -1 of Cd, and 60 and 80 μmol l -1 of Zn were added. The Cd/Zn-binding proteins induced in C. vulgaris exposed to Cd and Zn were referred to as Cd/Zn-MT-like proteins in which the mean molecular mass of the apo-MT-like was 6152 Da. The induced Cd/Zn-MT-like proteins might be involved in the detoxification of heavy metals, such as cadmium and zinc, by the alga

Full Text Available Microalgae cultivated in mixotrophic conditions have received significant attention as a suitable source of biofuel feedstock, based on their high biomass and lipid productivity. POME is one of the wastewaters generated from palm oil mills, containing important nutrients that could be suitable for mixotrophic microalgae growth. The aim of this research was to identify the growth of Chlorella vulgaris cultured in POME medium under mixotrophic conditions in relation to a variety of organic carbon sources added to the POME mixture. The research was conducted with 3 different carbon sources (D-glucose, crude glycerol and NaHCO3 in 40% POME, monitored over 6 days, under an illumination of 3000 lux, and with pH = 7. The biomass was harvested using an autoflocculation method and dry biomass was extracted using an ultrasound method in order to obtain the lipid content. The results show that C. vulgaris using D-glucose as carbon source gained a lipid productivity of 195 mg/l/d.

The impact of dietary supplementation with microalgae on goat's milk chemical composition, fatty acids (FA) profile and enzymes activities related to antioxidant mechanism has not been well documented. Thus, this study aimed to investigate the effects of dietary inclusion of Chlorella vulgaris on the following: (i) milk yield, chemical composition and FA profile, (ii) the activities of superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR), glutathione transferase (GST) and glutathione peroxidase (GSH-Px) in blood plasma and (iii) the activities of SOD, GR and lactoperoxidase (LPO) in milk of goats. Furthermore, the oxidative stress indicators for measuring total antioxidant and free radical scavenging activity [ferric reducing ability of plasma (FRAP) and 2, 2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) assays] and oxidative stress biomarkers [malondialdehyde (MDA) and protein carbonyls (PC)] were also determined in blood plasma and milk of the animals. For this purpose, 16 cross-bred goats were divided into two homogenous groups. Each goat of both groups was fed individually with alfalfa hay and concentrates separately. The concentrates of the control group (Control) had no microalgae, while those of the Chlorella group were supplemented with 10 g lyophilized Chlorella vulgaris/kg concentrates (Chlorella). Thus, the average intake was 5.15 g Chlorella vulgaris/kg DM. The results showed that the dietary inclusion of Chlorella vulgaris had not noticeable impact on goat's milk yield, chemical composition and FA profile. Significantly higher SOD (by 10.31%) and CAT (by 18.66%) activities in the blood plasma of goats fed with Chlorella vulgaris compared with the control were found. Moreover, the dietary supplementation with Chlorella vulgaris caused a significant increase in SOD (by 68.84%) activity and a reduction in PC (by 24.07%) content in goat's milk. In conclusion, the Chlorella vulgaris inclusion in goat's diets improved the

Five nominally freshwater microalgae (Chlorella vulgaris, Choricystis minor, Neochloris sp., Pseudococcomyxa simplex, Scenedesmus sp.) with a known ability to produce high-levels of lipids for possible use as fuel oils were evaluated for their ability to thrive and produce lipids in seawater and brackish water. Only C. vulgaris was found to thrive and produce lipids in full strength seawater. Seawater tolerant strains of C. vulgaris are unusual. Lipid productivity in nutrient sufficient seawater exceeded 37mgL -1 d -1 and was nearly 2-fold greater than in freshwater. Although other microalgae such as C. minor had higher lipid productivities (e.g. 45mgL -1 d -1 ), they did not thrive in seawater. The lipid content of the C. vulgaris biomass was nearly 16% by dry weight. The calorific value of the seawater-grown C. vulgaris biomass exceeded 25kJg -1 . Compared to continuously illuminated cultures, a 12/12h light-dark cycle reduced lipid productivity of C. vulgaris by ∼30%, but did not affect the lipid content of the biomass. Biomass yield on phosphate was nearly 27% higher in seawater compared to in freshwater. While C. vulgaris has been extensively studied in freshwater, it has not been examined to any detail in full strength seawater. Studies in seawater are essential for any future large scale production of algal oils for biofuels: seawater is available cheaply and in large amounts whereas there is a global shortage of freshwater.

Full Text Available The article is devoted to the semantic and chronological analysis of the images on the plate of white tuff discovered in the city of Stavropol. The central part of the relief is occupied with the image of table – an altar with hoisted bull head (in the background and the hanging part of bull skin (in the foreground. Between the protruding edges of the hanging skin and lower to the ground (between the legs of the altar an ancient Greek phrase carved in three lines. The composition is completed by flanking images of two figures in long robes depicted in profile, symmetrically turned to the head of the bull. The figure at the right is an image of a man with a long beard, the lower edge of which is bent forward (priest or king. The figure at the left is a female (queen. Both the man and the woman are holding ritual vessels in hands. The plot of bull sacrifice is typical for the cultural traditions of ancient Greece as well as for ancient eastern states. The fact of combining images and inscriptions peculiar of the Hellenistic culture and ancient Iranian mythology on the Stavropol altar should be associated with the religious policy pursued by the Pontic kings since the second half of the 3rd century BC till the Common Era. This policy was focused on the gradual replacement of local cults by Greek ones in the official pantheon. The reasons for the Asia Minor altar existence in the Stavropol Upland include: 1 the military expeditions of the Sarmatians to Asia Minor in 2nd – 1st centuries BC; 2 the establishment of political and economic ties by the North Caucasus population with the state of Seleucids in the 2nd century BC, with Parthia in the 2nd – 1st centuries BC, and especially with the kingdom of Pontus in the 1st century BC.

Acne vulgaris is the most common cutaneous disorder affecting adolescents and young adults. Some studies have reported an association between serum zinc levels and acne vulgaris. We aimed to evaluate the serum zinc level in patients with acne vulgaris and compare it with healthy controls. One hundred patients with acne vulgaris and 100 healthy controls were referred to our clinic. Acne severity was classified according to Global Acne Grading System (GAGS). Atomic absorption spectrophotometry was used to measure serum zinc levels. Mean serum level of zinc in acne patients and controls was 81.31 ± 17.63 μg/dl and 82.63 ± 17.49 μg/dl, respectively. Although the mean serum zinc level was lower in acne group, it was not statistically significant (P = 0.598). There was a correlation between serum zinc levels with severity and type of acne lesions. The results of our study suggest that zinc levels may be related to the severity and type of acne lesions in patients with acne vulgaris. Relative decrease of serum zinc level in acne patients suggests a role for zinc in the pathogenesis of acne vulgaris.

Antimicrobial peptides are considered as a potential alternative to antibiotic treatment in acne vulgaris because the development of a resistant strain of Propionibacterium acnes is problematic. Granulysin can be regarded as an ideal substance with which to treat acne because it has antimicrobial and anti-inflammatory effects. This study was performed to explore the effectiveness of granulysin-derived peptides (GDPs) in killing P. acnes in vitro under a standard microbiologic assay and to evaluate their potential use in a topical agent for the treatment of acne vulgaris. Twenty different peptides based on the known sequence of a GDP were synthesized and tested in vitro for antimicrobial activity. Thirty patients with facial acne vulgaris were instructed to apply a topical formulation containing synthetic GDP to acne lesions twice per day for 12 weeks. A newly synthesized peptide in which aspartic acid was substituted with arginine, and methionine was substituted with cysteine, showed the highest antimicrobial activity against P. acnes. Moreover, it was effective against both Gram-positive and Gram-negative bacteria in vitro. After treatment with the topical formulation containing 50 ppm of synthetic peptide for 12 weeks, a significant reduction in the number of pustules was observed, regardless of the increase in the number of comedones. In addition, a significant reduction in the clinical grade of acne based on the Korean Acne Grading System (KAGS) was evident. Synthesized GDP shows strong antimicrobial activity against P. acnes in vitro. The clinical improvement observed suggests a topical formulation containing the GDP has therapeutic potential for the improvement of inflammatory-type acne vulgaris by its antimicrobial activity. © 2015 The International Society of Dermatology.

Full Text Available The competition between populations of the parasitoids C. grandis and B. vulgaris was studied using larvae of Euscepes postfasciatus (Fairmaire as an alternative host. A series of biological parameters was observed and related to the competitive abilities of both parasitoid species. They were capable of colonizing and maintaining their populations regardless of host location. The population growth of C. grandis and B. vulgaris, based on fecundity was not affected by the competition. The parasitism and survivorship to the adult stage were affected by competition, except when the host was located at the bottom of the rearing cage. C. grandis performed better than B. vulgaris independently of the competition and host location, but it did not exclude the other species.Catolaccus grandis (Burks e Bracon vulgaris Ashmead são os principais parasitóides do bicudo-do-algodoeiro Anthonomus grandis Boheman no Nordeste do Brasil. É importante que se determinem as interações entre esses parasitóides e o seu efeito em programas de controle biológico dessa praga com os mesmos. A competição entre os parasitóides C. grandis e B. vulgaris foi estudada, utilizando-se larvas de Euscepes postfasciatus Fairmaire como hospedeiro alternativo. A fecundidade de C. grandis e B. vulgaris baseada na produção de ovos, não foi afetada pela competição, mas o parasitismo e a produção de adultos desses parasitóides foram afetados pela competição, exceto quando o hospedeiro se encontrava na base da caixa de criação. Independentemente da competição e da localização do hospedeiro, C. grandis apresentou melhor desempenho que B. vulgaris, mas não excluiu as populações da outra espécie de parasitóide.

Full Text Available Hexavalent chromium [Cr(VI] is a toxic oxidized form and an important metal pollutant in the water bodies. Biosorption of chromium(VI offers a potential alternative to conventional metal removal methods. Dried biomass of Chlorella vulgaris was used as biosorbent for the removal of Cr(VI from electroplating and galvanizing industry effluents as a function of biosorbent dosage, contact time, pH, salinity and initial metal ion concentration. Batch experiments were conducted for biosorption and the optimum conditions were 1 g/L biomass, 4 h contact time, pH 2 and 2.893 mS/cm of electrical conductivity. The chromium biosorption was strictly pH dependent with a maximum Cr removal of 63.2 mg/L at pH 2. Highest Cr removal at a concentration of 81.3 mg/L was observed at Electrical conductivity (EC value of 2.893 mS/cm. A comparison of Langmuir and Freundlich isotherm models revealed that Freundlich isotherm model fitted the experimental data based on R2, qmax and standard error values. The results suggest that C. vulgaris biomass could be considered a promising low-cost biosorbent for the removal of Cr(VI from electroplating and galvanizing industry effluents.

We studied the effects of trophic modes related to glucose and light (photoautotrophy, mixotrophy and heterotrophy) on growth, cellular components and carbon metabolic pathway of Chlorella vulgaris. The parameters about growth of algal cells were investigated by using spectroscopy and chromatography techniques. When trophic mode changed from photoautotrophy to mixotrophy and to heterotrophy successively, the concentrations of soluble sugar, lipid and saturated C16/C18 fatty acids in C. vulgaris increased, whereas the concentrations of unsaturated C16, C18 fatty acids, proteins, photosynthetic pigments and 18 relative amino acids decreased. Light and glucose affect the growth, metabolism and the biochemical components biosynthesis of C. vulgaris. Addition of glucose can promote algal biomass accumulation, stimulate the synthesis of carbonaceous components, but inhibit nitrogenous components. Under illumination cultivation, concentration and consumption level of glucose decided the main trophic modes of C. vulgaris. Mixotrophic and heterotrophic cultivation could promote the growth of algal cells.

In this study, Chlorella vulgaris (C. vulgaris) was treated with ethephon at low (50 μM) and high (200 μM) concentrations in medium and harvested at 0, 7, and 14 days, respectively. The presence of ethephon led to significant metabolic changes in C. vulgaris, with significantly higher levels of α-tocopherol, γ-aminobutyric acid (GABA), asparagine, and proline, but lower levels of glycine, citrate, and galactose relative to control. Ethephon induced increases in saturated fatty acids but decreases in unsaturated fatty acids. The levels of highly saturated sulfoquinovosyldiacylglycerol species and palmitic acid bound phospholipids were increased on day 7 of ethephon treatment. Among the metabolites, the productivities of α-tocopherol (0.70 μg/L/day) and GABA (1.90 μg/L/day) were highest for 50 and 200 μM ethephon on day 7, respectively. We propose that ethephon treatment involves various metabolic processes in C. vulgaris and can be an efficient way to enrich the contents of α-tocopherol and GABA.

Full Text Available Premise of the study: Vigna unguiculata is an economically important legume, and the complexity of its variability and evolution needs to be further understood. Based on publicly available databases, we developed chloroplast microsatellite primers to investigate genetic diversity within V. unguiculata and its related species Phaseolus vulgaris. Methods and Results: Twelve polymorphic chloroplast microsatellite markers were developed and characterized in 62 V. unguiculata individuals. The number of alleles per locus varied between two and four, the unbiased haploid diversity per locus ranged from 0.123 to 0.497, and the polymorphism information content varied from 0.114 to 0.369. In cross-species amplifications, nine of these markers showed polymorphism in 29 P. vulgaris individuals. Conclusions: The newly developed chloroplast microsatellite markers exhibit variation in V. unguiculata as well as their transferability in P. vulgaris. These markers can be used to investigate genetic diversity and evolution in V. unguiculata and P. vulgaris.

Black carbon (BC) derived from incomplete combustion of fossil fuels and biomass has received increasing attention due to their potential importance in a wide range of biogeochemical processes. China has been generally considered as the world's largest BC emitter. Due to a combination of the prevailing East Asia monsoon and large amounts of riverine outflow, BC released from China can be transported to the adjacent continental shelf seas, the Bohai Sea (BS) and Yellow Sea (YS). Based on measurements of BC in 191 surface sediments, 36 riverine water, and 2 seawater samples, as well as the reported BC data set of the aerosol samples in the Bohai Rim, the concentration, flux, and budget of BC in the BS and YS were investigated. The spatial distribution of the BC concentration in surface sediments was largely influenced by the regional hydrodynamic conditions, with high values mainly occurring in the central mud areas. The BC burial flux in the BS and YS ranged from 4 to 1100 μg/cm2/yr, and averaged 166 ± 200 μg/cm2/yr. The area-integrated sedimentary BC sink flux in the entire BS and YS was ~325 Gg/yr. The BC budget calculated in the BS showed that atmospheric deposition and riverine discharge played comparable importance in delivering BC to the BS, and sequestration to bottom sediments was the major BC output pattern, accounting for ~88% of the total input BC. Besides, we attempted to apportion the BC sources in the BS and YS surface sediments using PAHs (organic molecular proxies cogenerated with BC) and BC as an input data to the Positive Matrix Factorization (PMF) receptor model. Results showed that ~83% of the sediment BC was attributed to the combustion of fossil fuels, and the remaining ~17% was from biomass burning. Due to the differences in their production mechanisms and therefore physicochemical properties, the above distinction and quantification would help us better understand their different environmental behaviors in the complex continental shelf

Full Text Available The objective of this work was to study the activity of sucrose metabolizing enzymes in extracts of cell suspension cultures of Bauhinia forficata Link, Curcuma zedoaria Roscoe and Phaseolus vulgaris L. Invertase pathway was identified in the three studied species. Sucrose synthase pathway was also responsible for sucrose metabolism in Curcuma zedoaria and Phaseolus vulgaris cells. Activity values higher than 300 nmol min-1 mg-1 of protein were found for acid and neutral invertases, UDPglucose pyrophosphorylase and phosphoglucomutase in the cell extract of the three plant species. Sucrose synthase showed low activity in Bauhinia forficata cells. As sucrose concentration in the culture medium decreased, sucrose synthase activity increased in C. zedoaria and P. vulgaris cells. The glycolytic enzymes activity gradually reduced at the end of the culture period, when carbohydrate was limited.O objetivo deste trabalho foi estudar as enzimas do metabolismo da sacarose em culturas de célula em suspensão de Bauhinia forficata Link, Curcuma zedoaria Roscoe e Phaseolus vulgaris L. A via da invertase foi identificada nas três espécies estudadas. A via da sacarose sintase também foi responsável pelo metabolismo da sacarose em células de Curcuma zedoaria e Phaseolus vulgaris. Foram encontradas atividades maiores que 300 nmol min-1 mg-1 de proteína das enzimas invertase ácida e alcalina, UDPglicose pirofosforilase e fosfoglicomutase no extrato celular das três espécies de plantas. A sacarose sintase mostrou atividade baixa nas células de Bauhinia forficata. À medida que a concentração de sacarose no meio de cultura diminuiu, a atividade da sacarose sintase aumentou em células de Curcuma zedoaria e Phaseolus vulgaris. Ao final do período de cultura, quando os carboidratos se tornaram limitantes, as atividades das enzimas glicolíticas reduziram-se gradualmente.

Acne vulgaris is a chronic condition affecting more than 85% of adolescents and young adults. It is one of the most common diseases affecting humanity and its impact on quality of life (QoL) is important. The impact of acne on QoL in Indian patients remains undocumented. The study was undertaken to detect the impact of acne vulgaris and related factors that may influence the QoL. Materials and Methods: This was a hospital-based, prospective, cross-sectional, prestructured, questionnaire-based study done on 140 consenting individuals, who attended the Dermatology outpatient department. Acne vulgaris was graded using simple grading system. QoL was measured using a combination of skin disease-specific (Dermatological Life Quality Index (DLQI)) and acne-specific (Cardiff Acne Disability Index (CADI)) questionnaires. Results: Majority of our study population were students (103, 73.6%). Face (139, 99.3%) was the commonest site of acne and comedones 133, 95% were the commonest type of lesion. Most of the individuals 66, 47.1% were observed to have grade 1 acne. The mean DLQI score was 6.91 and the mean CADI score was 5.2. Association between the scores was statistically significant. Age, occupation, marital status, family, and treatment history played a role in affecting the QoL. Diet, smoking, and alcohol did not influence the QoL. Conclusion: Though acne had impact on patient's QoL, it was less severe in our study. It is important for health professionals to incorporate QoL measurements when managing acne patients to provide better and appropriate care. PMID:25657394
The Atlantic Ocean: An Impassable Barrier for the Common Octopus, Octopus vulgaris

Octopus vulgaris (Lamarck 1798) inhabits the Mediterranean, the temperate and tropical coastal waters of the Atlantic Ocean and is also present in the south Indian Ocean and Japan. We questioned the reported widespread distribution and especially the amphi-Atlantic distribution of O. vulgaris by comparing patterns of genetic variation in the Cytochrome Oxidase Subunit I (COI), the 17th intron of the Na(+)/K(+)-ATPase alpha subunit (Na/K-ATPase 17th intron), and 16S genes from several populations throughout the presumed distribution. Bayesian genealogies based on COI sequences resulted in three monophyletic lineages: a Caribbean, a Eurafrican and a Japanese one. The Eurafrican lineage is more closely related to the Japanese than to the Caribbean lineage. Within the Caribbean, the most common mitochondrial haplotype is shared by all sampled locations except for Curaçao. The most common COI haplotype in the Eurafrican group is shared by all populations. The Caribbean octopus exhibits a divergence of 11.5% compared to the Eurafrican and Japanese octopus, whereas the latter groups are 3.1% divergent. The Na/K-ATPase 17th intron data from Caribbean and Mediterranean/Atlantic Spain octopods is concordant with the mitochondrial data set, separating these two populations. The 16s data is still being analysed, but preliminary analysis supports the dual population hypothesis. The reciprocal monophyly observed with both COI and Na/K-ATPase 17th intron between the Caribbean and European O. vulgaris suggests the historical cessation of gene flow between the two sides of the Atlantic and highlights the presence of a highly differentiated Caribbean lineage.

Full Text Available Chlorella vulgaris and Nannochloropsis oculata are a highly potential microalgae to be used in pilot-scale of biodiesel synthesis. The essential content from these microalgae is the fatty acid of lipid which is the main target for the feed and biodiesel industries. One of the key factor in improving lipid microalgae are the arrangemment of nutrients in the growth medium. Research on the regulation of nutrients using bicarbonate (HCO3- as an additional inorganic carbon source has been done by many studies, but the yield of lipids obtained has not been much. The aim of the study was to improve the lipid yield of Chlorella vulgaris and Nannochloropsis oculata. Variation of [HCO3-] which added to Walne medium were 25 ppm and 75 ppm, while the Walne medium without the addition of bicarbonate acts as control. The results showed that [HCO3-] 75 ppm could increase Chlorella vulgaris biomass by 0.9162 g/l with 17.0% wt, while Nannochloropsis oculata produced the greatest lipid content in [HCO3-] 25 ppm of 20.3% wt and the largest biomass on [HCO3-] 75 ppm of 1.7233 g/l.

Nutrient utilization and oxygen production by Chlorella Vulgaris in a hybrid membrane bioreactor and algal membrane photobioreactor system

KAUST Repository

Najm, Yasmeen Hani Kamal; Jeong, Sanghyun; Leiknes, TorOve

2017-01-01

This work studied oxygen production and nutrient utilization by Chlorella Vulgaris at different organic/inorganic carbon (OC/IC) and ammonium/nitrate (NH4+-N/NO3--N) ratios to design a hybrid aerobic membrane bioreactor (MBR) and membrane photobioreactor (MPBR) system. Specific oxygen production by C. vulgaris was enough to support the MBR if high growth is accomplished. Nearly 100% removal (or utilization) of PO43--P and IC was achieved under all conditions tested. Optimal growth was achieved at mixotrophic carbon conditions (0.353 d-1) and the highest NH4+-N concentration (0.357 d-1), with preferable NH4+-N utilization rather than NO3--N. The results indicate the potential of alternative process designs to treat domestic wastewater by coupling the hybrid MBR - MPBR systems.

2011-01-01

The major objective of the present study was to investigate the role of iron and manganese on the formation of haloacetic acids (HAAs) when algae are chlorinated at different pHs. The results showed that both iron and manganese can reduce the yields of dichloroacetic acid (DCAA) and trichloroacetic acid (TCAA) on chlorinating green alga Chlorella vulgaris (C. vulgaris) at a pH range of 6.0-9.0, and the decline of DCAA and TCAA was shown to be more significant at the low pH range. At pH 6.0, DCAA and TCAA yields decreased by 44.5% and 57.3%, respectively with the addition of 0.5 mg L -1 iron, and decreased 39.5% and 49.4%, respectively with the addition of 0.5 mg L -1 manganese. The main reason for decreasing the yields of HAAs as shown by scanning electron microscope (SEM) is that Fe(OH) 3(am) or MnO 2(am) coat the algal cells , which then improves their agglomeration of algal cells which is also revealed by the laser particle size analysis (LPSA).

Chlorella vulgaris is a green microalga that contains various antioxidants, such as carotenoids and chlorophylls. In this study, antioxidants from C. vulgaris were extracted using pressurized liquid extraction (PLE), which has been recently used for bioactive compound extraction. The antioxidant capacity of individual compounds in chlorella was determined by online HPLC ABTS(*+) analysis. According to the antioxidant analysis of total extracts, the extraction yield, radical scavenging activity, and phenolic compounds using PLE were relatively high compared to those obtained using maceration or ultrasound-assisted extraction. On the basis of online HPLC ABTS(*+) analysis, the 15 major antioxidants from chlorella extracts were identified as hydrophilic compounds, lutein and its isomers, chlorophylls, and chlorophyll derivatives. Using PLE at high temperature (85-160 degrees C) significantly increased antioxidant extraction from chlorella, improving the formation of hydrophilic compounds and yielding more antioxidative chlorophyll derivatives. Online HPLC ABTS(*+) analysis was a useful tool for the separation of main antioxidants from PLE extracts and allowed the simultaneous measurement of their antioxidant capacity, which clearly showed that PLE is an excellent method for extracting antioxidants from C. vulgaris.

Chlorella vulgaris was cultivated under limitation and starvation and under controlled conditions using different concentrations of nitrate (NaNO 3 ) and phosphate (K 2 HPO 4 and KH 2 PO 4 ) chemicals in modified Bold basal medium (BBM). The biomass and lipid production responses to different media were examined in terms of optical density, cell density, dry biomass, and lipid productivity. In the 12-day batch culture period, the highest biomass productivity obtained was 72.083 mg L -1 day -1 under BBM - N control P limited condition. The highest lipid content, lipid concentration, and lipid productivity obtained were 53.202 %, 287.291 mg/L, and 23.449 mg L -1 day -1 under BBM - N Control P Deprivation condition, respectively. Nitrogen had a major effect in the biomass concentration of C. vulgaris, while no significant effect was found for phosphorus. Nitrogen and phosphorus starvation was found to be the strategy affecting the lipid accumulation and affected the lipid composition of C. vulgaris cultures.

Full Text Available This study on blooming biology, nectar secretion, pollen production and insect visitation of Aquilegia vulgaris L. was carried out in 2009 and 2011 in Lublin. The peak of flower opening during the day was between 5.00 and 7.00 (GMT +2. The flowers are protandrous with the female phase beginning approx. on the 3rd day of anthesis. The dynamics of nectar secretion and pollen shed from anthers (progressing from the central part of the androecium outwards support the reproductive system. The amount of nectar accumulated in the spurs increased from the bud stage and was the highest in the phase with approx. ¾ of dehisced anthers, usually on the 3rd day of flower life. Then, towards the end of anthesis, the amount of secreted and accumulated nectar decreased. The number of anthers developed per flower varied from 41 to 61 (mean = 49.1. The mass of pollen per 100 anthers averaged 6.7 mg. Pollen production per flower (mean = 3.28 mg slightly varied between years and was mainly correlated with the number of developed anthers. Estimated pollen yield was 1.69 g per m2 and sugar yield 1.22 g per m2. Species from the genus Bombus were the main flower visitors, with B. terrestris being the most frequent forager.

This study aimed to investigate the biological characterization of HIV type 1 (HIV-1) CRF07_BC infection among men who have sex with men (MSM). From November 2011 to November 2013, a total of 66 blood samples were collected from MSM with acute HIV-1 infection with CRF07_BC subgroup strains. Deletion in the gag p6 region was detected by sequence alignment and comparative analysis. Peripheral blood mononuclear cells (PBMCs) of HNXX1301-1307 samples were separated by density gradient centrifugation. Nested polymerase chain reaction (nPCR) was used to amplify the viral DNA. The near full-length HIV-1 DNA products were ligated to the long terminal repeat (LTR) vector plasmid (07BCLTR) to construct a full-length HIV clone. The molecular clone was transfected into HEK-293T cells, TZM-b1 cells and patients' PBMCs. The pregenome of an infectious molecular clone of HIV-1 (pNL4-3) was amplified, and a subclone with CRF07_BC was developed to construct the full-length chimeric molecular clone pNL4-3/07BCLTR. Detection of p24 antigen and luciferase activity was used to measure the in vitro infectivity of pNL4-3/07BCLTR. Among the 66 MSM patients infected with CRF07_BC strains, deletion mutations of the Gag P6 proteins were found in 7 of 18CRF07_BC strains; deletion mutations of 2-13 amino acids in different regions were discovered in 6 strains; and the remaining 42 strains did not show deletions. Seven strains with amino acids deficiency in the P6 protein accounted for 27% of all strains and 75% of all deletion genotype strains. A total of 186 full-length molecular clones of CRF07_BC were constructed. There were 5, 9, 10 and 11 clones of HNXX1302, HNXX1304, HNXX1305 and HNXX1306 that resulted in p24-positive supernatant when transfected into HEK-293T cells. Full-length clones of HNXX1302, HNXX1304, HNXX1305 and HNXX1306 showed slight infection in the transfected TZM-b1 cells, as judged by the fluorescence values of TZM-b1 cells 48h post-transfection.

An alternative for this problem is the usage of bamboo in the production of vegetable coal, as it is a species which is tolerant to various types of environment and presents a good productive capacity. In this context, the present study aimed to assess the production potential of vegetable coal of Bambusa vulgaris Schrad, cultivated in Timon, MA. The samples were collected in a bamboo grove of 48,56 ha divided into four stands (treatments, located in the municipality of Timon, MA. Subsequently, taken to the Laboratory of Wood Technology of the UFCG/CSTR, where the basic density of the bamboo poles, the efficiency in the conversion into coal, efficiency in pyrolysis liquid, incondensable gases and immediate chemical analysis were determined. The average basic density of the bamboo was of 490kg/m3, not presenting significant difference between the averages of the four treatments. The average yield in vegetable coal was of 39,05%, and the treatments 1 and 4 presented higher values, with averages of 40,34% and 39,85%, however they did not differ statistically. The average yield of the condensable gases was of 12,17%. The apparent density varied from 1,945 to 2,833 g/cm3. The average contents of volatile materials, fixed carbon and fixed carbon efficiency were respectively 28,55%, 64,11% and 25,04%, not presenting significant difference among the treatments According to the analysis carried out, it was verified that the vegetable coal produced from the poles of Bambusa vulgaris Schrad. has potential for commercialization and use as an energy source.

Summary The aim of this study was to test three flat plate photobioreactor configurations for growth of Chlorella vulgaris under non‐axenic conditions and to characterize and quantify associated bacterial communities. The photobioreactor cultivations were conducted using tap water‐based media to introduce background bacterial population. Growth of algae was monitored over time with three independent methods. Additionally, the quantity and quality of eukaryotes and bacteria were analysed using culture‐independent molecular tools based on denaturing gradient gel electrophoresis (PCR‐DGGE) and quantitative polymerase chain reaction (QPCR). Static mixers used in the flat plate photobioreactors did not generally enhance the growth at the low light intensities used. The maximum biomass concentration and maximum specific growth rate were 1.0 g l−1 and 2.0 day−1 respectively. Bacterial growth as determined by QPCR was associated with the growth of C. vulgaris. Based on PCR‐DGGE, bacteria in the cultures mainly originated from the tap water. Bacterial community profiles were diverse but reproducible in all flat plate cultures. Most prominent bacteria in the C. vulgaris cultures belonged to the class Alphaproteobacteria and especially to the genus Sphingomonas. Analysis of the diversity of non‐photosynthetic microorganisms in algal mass cultures can provide useful information on the public health aspects and unravel community interactions. PMID:21936882

The toxic effects of cadmium (Cd) on the green alga Chlorella vulgaris were investigated by following the response to Cd of various toxicity endpoints (cell growth, cell size, photochemical efficiency of PSII in the light or Φ(PSII), maximal photochemical efficiency or Fv/Fm, chlorophyll a fluorescence, esterase activity, and cell viability). These toxicity endpoints were studied in laboratory batch cultures of C. vulgaris over a long-term 96-h exposure to different Cd concentrations using flow cytometry and pulse amplitude modulated fluorometry. The sequence of sensitivity of these toxicity endpoints was: cell yield > Φ(PSII) ≈ esterase activity > Fv/Fm > chlorophyll a fluorescence ≈ cell viability. It is shown that cell apoptosis or cell death only accounted for a minor part of the reduction in cell yield even at very high algistatic free Cd²⁺ concentrations, and other mechanisms such as blocked cell divisions are major contributors to cell yield inhibition. Furthermore, cadmium may affect both the electron donors and acceptors of the electron transport chain at high free Cd²⁺ concentration. Finally, the resistance of cells to cell death was size-dependent; medium-sized cells had the highest toxicity threshold. The present study brings new insights into the toxicity mechanisms of Cd in C. vulgaris and provides a detailed comparison of the sensitivity of various Cd toxicity endpoints. © 2013 SETAC.

In acne vulgaris, antimicrobial peptides (AMPs) could play a dual role; i.e., protective by acting against Propionibacterium acnes, pro-inflammatory by acting as signalling molecules. The cutaneous expression of 15 different AMPs was investigated in acne patients; furthermore, the impact of isotretinoin therapy on AMP expression was analysed in skin biopsies from 13 patients with acne vulgaris taken before, during and after a 6-month treatment cycle with isotretinoin using quantitative real-time polymerase chain reaction. Cutaneous expression of the AMPs cathelicidin, human β-defensin-2 (HBD-2), lactoferrin, lysozyme, psoriasin (S100A7), koebnerisin (S100A15), and RNase 7 was upregulated in untreated acne vulgaris, whereas α-defensin-1 (HNP-1) was downregulated compared to controls. While relative expression levels of cathelicidin, HBD-2, lactoferrin, psoriasin (S100A7), and koebnerisin (S100A15) decreased during isotretinoin treatment, only those of cathelicidin and koebnerisin returned to normal after 6 months of isotretinoin therapy. The increased expression of lysozyme and RNase 7 remained unaffected by isotretinoin treatment. The levels of granulysin, RANTES (CCL5), perforin, CXCL9, substance P, chromogranin B, and dermcidin were not regulated in untreated acne patients and isotretinoin had no effect on these AMPs. In conclusion, the expression of various AMPs is altered in acne vulgaris. Isotretinoin therapy normalizes the cutaneous production of distinct AMPs while the expression of others is still increased in healing acne. Considering the antimicrobial and pro-inflammatory role of AMPs, these molecules could serve as specific targets for acne therapy and maintenance of clinical remission.

Strongylus vulgaris is regarded as the most pathogenic helminth parasite infecting horses. Migrating larvae cause pronounced endarteritis and thrombosis in the cranial mesenteric artery and adjacent branches, and thromboembolism can lead to ischemia and infarction of large intestinal segments. A recently developed serum ELISA allows detection of S. vulgaris-specific antibodies during the six-month-long prepatent period. A population of horses has been maintained at the University of Kentucky without anthelmintic intervention since 1979, and S. vulgaris has been documented to be highly prevalent. In 2012, 12 foals were born in this population, and were studied during a 12-month period (March-March). Weekly serum samples were collected to monitor S. vulgaris specific antibodies with the ELISA. Nine colts underwent necropsy at different time points between 90 and 300 days of age. At necropsy, Strongylus spp. and Parascaris equorum were identified to species and stage and enumerated. Initial statistical findings indicate a significant interaction between foal age and ELISA results (pvulgaris-directed maternal antibodies transferred in the colostrum, but then remained ELISA negative during their first three months of life. Foals born in February and March became ELISA positive at about 12 weeks of age, while those born in April and May went positive at about 15 and 21 weeks, respectively. Foal date of birth was significantly associated with ELISA results (pvulgaris burdens (pvulgaris, S. edentatus, and P. equorum burdens (pvulgaris larvae leaving the bloodstream and migrating back to the intestine.

Acne vulgaris affects about 85% of teenagers and may continue to adulthood. There are about two million visits to physicians per year for teenagers and the direct cost of acne treatment in the US exceeds $1 billion per year. A wide variety of treatment regimens exist for acne vulgaris including benzoil peroxide, retinoids, isotretinoids, keratolytic soaps, alpha hydroxy acids, azelaic acid, salicilic acid as well as hormonal, anti-androgen or antiseborrheic treatments. However, none of these methods is free of side effects and their exact role in therapy is not clear. In this paper apart from presenting the possible causes of acne vulgaris and its available drugs, recently published papers about medicinal plants used in the treatment of acne vulgaris were reviewed. Consumption of alternative and complementary medicine, including medicinal plants, is increasing and is common amongst patients affected by acne and infectious skin diseases. Medicinal plants have a long history of use and have been shown to possess low side effects. These plants are a reliable source for preparation of new drugs. Many plants seem to have inhibitory effects on the growth of bacteria, fungi and viruses in vitro. However, there are a few clinical evidences about the effectiveness and safety of these plants in the treatment of acne and other skin infections.
Green Tea and Other Tea Polyphenols: Effects on Sebum Production and Acne Vulgaris

Full Text Available Polyphenols are antioxidant molecules found in many foods including nuts, fruits, vegetables, chocolate, wine, and tea. Polyphenols have antimicrobial, anti-inflammatory, and antineoplastic properties. Recent studies suggest that tea polyphenols may be used for reducing sebum production in the skin and for treatment of acne vulgaris. This review examines the evidence for use of topically and orally ingested tea polyphenols against sebum production and for acne treatment and prevention. The PubMed database was searched for studies on tea polyphenols, sebum secretion, and acne vulgaris. Of the 59 studies found, eight met the inclusion criteria. Two studies evaluated tea polyphenol effects on sebum production; six studies examined tea polyphenol effects on acne vulgaris. Seven studies evaluated topical tea polyphenols; one study examined systemic tea polyphenols. None of the studies evaluated both topical and systemic tea polyphenols. Tea polyphenol sources included green tea (six studies and tea, type not specified (two studies. Overall, there is some evidence that tea polyphenols in topical formulation may be beneficial in reducing sebum secretion and in treatment of acne. Research studies of high quality and with large sample sizes are needed to assess the efficacy of tea polyphenols in topical and oral prevention of acne vulgaris and lipid synthesis by the sebaceous glands.

The purpose of this literature review is to evaluate the use of metformin as an adjunct therapy in the treatment of moderate-to-severe acne in those not diagnosed with polycystic ovary syndrome (PCOS) or androgen excess. The authors conducted independent literature searches. Results were limited to clinical trials and randomized controlled trials. Studies with participants diagnosed with moderateto-severe acne vulgaris taking metformin versus placebo or other active treatment were included;studies with participants diagnosed with PCOS or androgen excess were excluded. The authors found three studies consistent with the search guidelines that evaluated the effects of metformin as adjunct therapy in moderate to severe acne vulgaris. In eachstudy, metformin was an effective adjunct therapy in the treatment of moderate-to-severe acne vulgaris.

Dopamine D(2) receptor (D(2)DR)-mediated transmission in the striatum is remarkably flexible, and changes in its efficacy have been heavily implicated in a variety of physiological and pathological conditions. Although receptor-associated proteins are clearly involved in specific forms of synaptic plasticity, the molecular mechanisms regulating the sensitivity of D(2) receptors in this brain area are essentially obscure. We have studied the physiological responses of the D(2)DR stimulations in mice lacking the brain cytoplasmic RNA BC1, a small noncoding dendritically localized RNA that is supposed to play a role in mRNA translation. We show that the efficiency of D(2)-mediated transmission regulating striatal GABA synapses is under the control of BC1 RNA, through a negative influence on D(2) receptor protein level affecting the functional pool of receptors. Ablation of the BC1 gene did not result in widespread dysregulation of synaptic transmission, because the sensitivity of cannabinoid CB(1) receptors was intact in the striatum of BC1 knock-out (KO) mice despite D(2) and CB(1) receptors mediated similar electrophysiological actions. Interestingly, the fragile X mental retardation protein FMRP, one of the multiple BC1 partners, is not involved in the BC1 effects on the D(2)-mediated transmission. Because D(2)DR mRNA is apparently equally translated in the BC1-KO and wild-type mice, whereas the protein level is higher in BC1-KO mice, we suggest that BC1 RNA controls D(2)DR indirectly, probably regulating translation of molecules involved in D(2)DR turnover and/or stability.

Insulin-induced increases in diacylglycerol (DAG) have been suggested to result from stimulation of de novo phosphatidic acid (PA) synthesis and phosphatidylcholine (PC) hydrolysis. Presently, the authors found that insulin decreased PC levels of BC3H-1 myocytes and rat adipocytes by approximately 10-25% within 30 s. These decreases were rapidly reversed in both cell types, apparently because of increased PC synthesis de novo. In BC3H-1 myocytes, pertussis toxin inhibited PC resynthesis and insulin effects on the pathway of de novo PA-DAG-PC synthesis, as evidenced by changes in [ 3 H]glycerol incorporation, but did not inhibit insulin-stimulated PC hydrolysis. Pertussis toxin also blocked the later, but not the initial, increase in DAG production in the myocytes. Phorbol esters activated PC hydrolysis in both myocytes and adipocytes, but insulin-induced stimulation of PC hydrolysis was not dependent upon activation of PKC, since this hydrolysis was not inhibited by 500 μM sangivamycin, an effective PKC inhibitor. The results indicate that insulin increases DAG by pertussis toxin sensitive and insensitive (PC hydrolysis) mechanisms, which are mechanistically separate, but functionally interdependent and integrated. PC hydrolysis may contribute importantly to initial increases in DAG, but later sustained increases are apparently largely dependent on insulin-induced stimulation of the pathway of de novo phospholipid synthesis

Pemphigusis a bullous, rare and chronic autoimmune disease. There are two major forms of pemphigus: vulgaris and foliaceus. Epidemiological data and clinical outcome in patients diagnosed in the Brazilian Amazon states are still rare. To study the occurrence of the disease during the study period and analyze the epidemiological profile of patients, the most common subtype of pemphigus, and the clinical evolution of patients. Retrospective analysis of medical records of hospitalized patients with pemphigus foliaceus and pemphigus vulgaris in the period from 2003 to 2010 in Dermatology Service of Hospital Fundação Santa Casa de Misericórdia do Pará, Belém, Northern Brazil. We found a total of 20 cases of pemphigus during the study period, 8 of which were of foliaceus pemphigus and 12 of vulgaris pemphigus. Pemphigus foliaceus had the predominance of male patients (75%), showed satisfactory clinical evolution, and was characterized by absence of pediatric cases. Pemphigus vulgaris affected more women (66.7%), showed mean hospital stay of 1 to 3 months (50%), and there were three cases of death (25%). The prescribed immunosuppressive drugs included prednisone with or without combination of azathioprine and/or dapsone. Sepsis was associated with 100% of the deaths. The occurrence of the disease is rare, there are no familiar/endemic outbreaks in the sample. Evolution is usually favorable, but secondary infection is associated with worse prognosis. The choice of best drugs to treat pemphigus remains controversial.

This study investigated the short-term toxicity of azoxystrobin (AZ), one of strobilurins used as an effective fungicidal agent to control the Asian soybean rust, on aquatic unicellular algae Chlorella vulgaris. The median percentile inhibition concentration (IC₅₀) of AZ for C. vulgaris was found to be 510 μg L(-1). We showed that the algal cells were obviously depressed or shrunk in 300 and 600 μg L(-1) AZ treatments by using the electron microscopy. Furthermore, 19, 75, and 300 μg L(-1) AZ treatments decreased the soluble protein content and chlorophyll concentrations in C. vulgaris and altered the energy-photosynthesis-related mRNA expression levels in 48- and 96-h exposure periods. Simultaneously, our results showed that AZ could increase the total antioxidant capacity (T-AOC) level and compromise superoxide dismutase (SOD), peroxidase (POD), glutathione S transferase (GST), glutathione peroxidase (GPx) activities, and glutathione (GSH) content. These situations might render C. vulgaris more vulnerable to oxidative damage. Overall, the present study indicated that AZ might be toxic to the growth of C. vulgaris, affect energy-photosynthesis-related mRNA expressions, and induce reactive oxygen species (ROS) overproduction in C. vulgaris.

Reusing supernatant of microalgae culture medium can have inhibitory or toxic effects on the biomass production because of the release of organic metabolites by cells in the culture medium during their growth. This work investigated the impact of Chlorella vulgaris medium recycling on culture productivity, cells quality and accumulation of excreted metabolites in the culture medium. No significant impact on the C. vulgaris growth was observed after 63days of recycling, the productivity remained stable at around 0.55kgm-3day-1. Organic matters accumulated in supernatant were identified as biopolymers (BP) poor in nitrogen and with a size above 40kDa (probably polysaccharides), and small organic molecules (SOM) richer in nitrogen with a molecular size ranging from 1 to 3kDa. The concentration of biopolymers in the supernatant increased till to a maximum and then decreased, possibly consumed by bacteria, whereas small organic compounds accumulated in the medium. © 2013 Elsevier Ltd.

Acne vulgaris affects about 85% of adolescents, often extending into adulthood. Psychosocial impact of acne on health-related quality of life (QoL) has been identified, but it remains under-evaluated, especially in Indian patients. This study was aimed to assess the impact of acne and its sequelae on the QoL. This was a hospital-based, prospective, cross-sectional study done between June and November 2014 on 114 consenting patients above 15 years of age with acne vulgaris. Acne vulgaris and its sequelae were graded, and QoL was assessed by using Dermatology Life Quality Index (DLQI) questionnaire. Most cases (64%) were between 15 and 20 years. Females (57%) outnumbered males. Facial lesions (61.4%) and grade II acne were most common. Mean DLQI score was 7.22. DLQI scores were statistically influenced by the age of the patient, duration and grade of acne, acne scar, and postacne hyperpigmentation. This study showed significant impairment of QoL in acne patients. Assurance and counseling along with early treatment of acne vulgaris are important to reduce disease-related psychosocial sequelae and increase the efficacy of treatment.
Thyroid neoplasms after radiation therapy for adolescent acne vulgaris

There is a potential hazard of thyroid cancer after exposure to external irradiation for the treatment of adolescent acne vulgaris. We noted a 60% incidence of thyroid carcinoma among 20 patients with such a history, who were operated on for thyroid nodules during a five-year period. Eighty-three percent of the patients with carcinoma had either a follicular or a mixed papillary-follicular carcinoma; 17% had a papillary carcinoma; 33% had regional node metastases; none had evidence of distant metastases. The interval between radiation exposure and thyroidectomy ranged from nine to 41 years. This association of thyroid neoplasms and a prior history of radiation for acne vulgaris may be coincidental and therefore remains to be proved by retrospective surveys of large numbers of treated patients with appropriate controls

Recombinant Desulfovibrio vulgaris flavodoxin was produced in Escherichia coli. A complete backbone NMR assignment for the two-electron reduced protein revealed significant changes of chemical shift values compared to the oxidized protein, in particular for the flavine mononucleotide (FMN)-binding site. A comparison of homo- and heteronuclear NOESY spectra for the two redox states led to the assumption that reduction is not accompanied by significant changes of the global fold of the protein.The backbone dynamics of both the oxidized and reduced forms of D. vulgaris flavodoxin were investigated using two-dimensional 15 N- 1 H correlation NMR spectroscopy.T 1 , T 2 and NOE data are obtained for 95% of the backbone amide groups in both redox states. These values were analysed in terms of the 'model-free' approach introduced by Lipari and Szabo [(1982) J. Am. Chem. Soc., 104, 4546-;4559, 4559-;4570]. A comparison of the two redox states indicates that in the reduced species significantly more flexibility occurs in the two loop regions enclosing FMN.Also, a higher amplitude of local motion could be found for the N(3)H group of FMN bound to the reduced protein compared to the oxidized state

The NAD(+)-dependent cytosolic glyceraldehyde-3-phosphate dehydrogenase (GAPDH, EC 1.2.1.12), which is recognized as a key to central carbon metabolism in glycolysis and gluconeogenesis and as an important allozymic polymorphic biomarker, was purified from muscles of two marine species: the skeletal muscle of Sardina pilchardus Walbaum (Teleost, Clupeida) and the incompressible arm muscle of Octopus vulgaris (Mollusca, Cephalopoda). Comparative biochemical studies have revealed that they differ in their subunit molecular masses and in pI values. Partial cDNA sequences corresponding to an internal region of the GapC genes from Sardina and Octopus were obtained by polymerase chain reaction using degenerate primers designed from highly conserved protein motifs. Alignments of the deduced amino acid sequences were used to establish the 3D structures of the active site of two enzymes as well as the phylogenetic relationships of the sardine and octopus enzymes. These two enzymes are the first two GAPDHs characterized so far from teleost fish and cephalopod, respectively. Interestingly, phylogenetic analyses indicated that the sardina GAPDH is in a cluster with the archetypical enzymes from other vertebrates, while the octopus GAPDH comes together with other molluscan sequences in a distant basal assembly closer to bacterial and fungal orthologs, thus suggesting their different evolutionary scenarios.

The relation between fatty acid accumulation, activity of acetyl-CoA carboxylase (ACC), and consequently lipid accumulation was studied in the microalgae Chlorella vulgaris co-immobilized with the plant growth-promoting bacterium Azospirillum brasilense under dark heterotrophic conditions with Na acetate as a carbon source. In C. vulgaris immobilized alone, cultivation experiments for 6 days showed that ACC activity is directly related to fatty acid accumulation, especially in the last 3 days. In co-immobilization experiments, A. brasilense exerted a significant positive effect over ACC activity, increased the quantity in all nine main fatty acids, increased total lipid accumulation in C. vulgaris, and mitigated negative effects of nonoptimal temperature for growth. No correlation between ACC activity and lipid accumulation in the cells was established for three different temperatures. This study demonstrated that the interaction between A. brasilense and C. vulgaris has a significant effect on fatty acid and lipid accumulation in the microalgae.

The noncatalytic transformation of the crude lipid of Chlorella vulgaris (C. vulgaris) into fatty acid methyl ester (FAME) via a thermo-chemical process was mainly investigated in this work. The crude lipid of C. vulgaris was recovered by means of solvent extraction from C. vulgaris cultivated in a raceway pond. The conventional catalyzed transesterification of crude lipid of C. vulgaris is notably inhibited by the impurities contained in the crude lipid of C. vulgaris. These impurities are inevitably derived from the solvent extraction process for C. vulgaris. However, this work presents the noncatalytic transesterification of microalgal lipid into FAME, which could be an alternative option. For example, the noncatalytic transformation of microalgal lipid into FAME provides evidence that the esterification of free fatty acids (FFAs) and the transesterification of triglycerides can be combined into a single step less susceptible to the impurities and with a high conversion efficiency (∼97%).

In this study, zeolite was employed for the separation and recovery of P from synthetic wastewater and its use as phosphorus (P) source for the cultivation of the green microalga Chlorella vulgaris and the cyanobacterium Arthrospira (Spirulina) platensis. At P-loaded zeolite concentration of 0.15–1 g/L, in which P was limited, the two species displayed quite different behavior regarding their growth and biomass composition. C. vulgaris preferred to increase the intracellular P and did not synthesize biomass, while A. platensis synthesized biomass keeping the intracellular P as low as possible. In addition under P limitation, C. vulgaris did display some little alteration of the biomass composition, while A. platensis did it significantly, accumulating carbohydrates around 70% from about 15%–20% (control). Both species could desorb P from zeolite biologically. A. platensis could recover over 65% and C. vulgaris 25% of the P bounded onto zeolite. When P-loaded zeolite concentration increased to 5 g/L, P was adequate to support growth for both species. Especially in the case of C. vulgaris, growth was stimulated from the presence of P-loaded zeolite and produced more biomass compared to the control. PMID:25690037

Natural antioxidants are becoming a major focus because natural food ingredients are safer than synthetic types. The aim of this study was to investigate the protective effects of Thymus vulgaris and Bunium persicum essential oils (EO) on the oxidation of virgin olive oil (VOO) during accelerated storage. The antioxidant activities of EOs were compared with those of α-tocopherol and BHT. GC/MS analyses revealed that thymol (28.50%), p-cymene (27.14%), carvacrol (18.36%), and γ-terpinene (4.97%) are the main components of T. vulgaris EO, while cuminaldehyde (32.81%), γ-terpinene (16.02%) and p-cymene (14.07%) are the main components of B. persicum EO. Both EOs provided protection for the VOO, inhibiting the formation of primary and secondary oxidation products although T. vulgaris EO showed greater protection against the oxidation process than B. persicum EO. The effect of T. vulgaris essential oil on the oxidation inhibition of VOO was similar to that of BHT. α-Tocopherol showed no measurable effect on improving the oxidative stability of VOO. This study suggests that T. vulgaris and B. persicum EOs can be used to improve the oxidative stability of VOO. [es

ADP-glucose pyrophosphorylase (AGPase) regulates starch biosynthesis in higher plants and microalgae. This study measured the effect of the bacterium Azospirillum brasilense on AGPase activity in the freshwater microalga Chlorella vulgaris and formation of starch. This was done by immobilizing both microorganisms in alginate beads, either replete with or deprived of nitrogen or phosphorus and all under heterotrophic conditions, using d-glucose or Na-acetate as the carbon source. AGPase activity during the first 72h of incubation was higher in C. vulgaris when immobilized with A. brasilense. This happened simultaneously with higher starch accumulation and higher carbon uptake by the microalgae. Either carbon source had similar effects on enzyme activity and starch accumulation. Starvation either by N or P had the same pattern on AGPase activity and starch accumulation. Under replete conditions, the population of C. vulgaris immobilized alone was higher than when immobilized together, but under starvation conditions A. brasilense induced a larger population of C. vulgaris. In summary, adding A. brasilense enhanced AGPase activity, starch formation, and mitigation of stress in C. vulgaris. Copyright © 2014 Elsevier B.V. All rights reserved.
