Reasons for decision in the matter of TransCanada PipeLines Limited and TransCanada Keystone Pipeline GP Ltd. : application dated 5 June 2006 for leave to transfer pipeline facilities and for a determination of the transfer price

International Nuclear Information System (INIS)

2007-01-01

TransCanada Pipelines Limited and its fully owned subsidiary TransCanada Keystone Pipeline GP Ltd. applied to the National Energy Board in June 2006 for leave to transfer certain pipeline facilities comprising part of TransCanada's mainline natural gas transmission system from TransCanada to Keystone for use in Keystone's proposed new oil pipeline. The transfer would involve the conversion of the facilities from gas service to oil service for use in the Keystone Project. The new oil pipeline would extend from Hardisty Alberta to Wood River and Patoka, Illinois. It would initially provide access for western Canada crude oil producers to the southern Petroleum Administration Defence District (PADD) 2 region of the United states. This is a major refining area which presently has minimal access for western Canada crude oil because of the limited pipeline capacity into the region. The Board held a hearing process to seek the views of interested parties regarding the list of issues that should be considered in dealing with the application. The list of issues included arguments of the Communications, Energy and Paperworkers Union of Canada (CEP) regarding the Board's jurisdiction; regulatory standards; energy supply markets and pipelines; potential impacts of the transfer such as potential costs to gas shippers and the impact of the transfer on mainline operations; and, the transfer at net book value (NBV). This document presented the Board's views on the transfer and the public interest. After considering all factors, the Board approved the sale and purchase of the Facilities from TransCanada to Keystone. The Board further ordered that TransCanada may reduce the mainline rate base by the NBV of the facilities upon their transfer to Keystone, and that Keystone may include the NBV in its pipeline oil plant upon the transfer of the facilities. 5 tabs., 14 figs., 6 appendices

Incidence of Fusarium spp. and Levels of Fumonisin B1 in Maize in Western Kenya

Kedera, C. J.; Plattner, R. D.; Desjardins, A. E.

1999-01-01

Maize kernel samples were collected in 1996 from smallholder farm storages in the districts of Bomet, Bungoma, Kakamega, Kericho, Kisii, Nandi, Siaya, Trans Nzoia, and Vihiga in the tropical highlands of western Kenya. Two-thirds of the samples were good-quality maize, and one-third were poor-quality maize with a high incidence of visibly diseased kernels. One hundred fifty-three maize samples were assessed for Fusarium infection by culturing kernels on a selective medium. The isolates obtained were identified to the species level based on morphology and on formation of the sexual stage in Gibberella fujikuroi mating population tests. Fusarium moniliforme (G. fujikuroi mating population A) was isolated most frequently, but F. subglutinans (G. fujikuroi mating population E), F. graminearum, F. oxysporum, F. solani, and other Fusarium species were also isolated. The high incidence of kernel infection with the fumonisin-producing species F. moniliforme indicated a potential for fumonisin contamination of Kenyan maize. However, analysis of 197 maize kernel samples by high-performance liquid chromatography found little fumonisin B1 in most of the samples. Forty-seven percent of the samples contained fumonisin B1 at levels above the detection limit (100 ng/g), but only 5% were above 1,000 ng/g, a proposed level of concern for human consumption. The four most-contaminated samples, with fumonisin B1 levels ranging from 3,600 to 11,600 ng/g, were from poor-quality maize collected in the Kisii district. Many samples with a high incidence of visibly diseased kernels contained little or no fumonisin B1, despite the presence of F. moniliforme. This result may be attributable to the inability of F. moniliforme isolates present in Kenyan maize to produce fumonisins, to the presence of other ear rot fungi, and/or to environmental conditions unfavorable for fumonisin production.

Crystallinity and the effect of ionizing radiation in polyethylene. V. Distribution of trans-vinylene and trans, trans conjugated double bonds in linear polyethylene

International Nuclear Information System (INIS)

Patel, G.N.

1975-01-01

Freeze-dried chain folded single crystals and the single crystals without amorphous surface layers (crystalline cores) of different thicknesses of linear polyethylene were irradiated with 60 Co γ-rays up to 600 Mrad. Concentration of trans-vinylene double bonds and conjugated diene produced during irradiation of the crystals was measured by infrared. Concentrations of trans-vinylene and of the conjugated diene were independent of thickness of crystalline core which suggest that the double bonds were randomly distributed in the crystalline parts of the crystals. Concentrations of trans-vinylene and of conjugated double bonds were lower in chain-folded crystals than in the crystalline cores and this suggests that the folds (amorphous surface layers) are less preferential sites for formation of the double bonds. The zero-order growth and first-order decay kinetics of trans-vinylene double bonds was studied by the equation derived by Dole et al. The equation is strictly obeyed up to 300 Mrad and the results then deviate. Since there is the decay of trans-vinylene double bonds and though there are no crosslinks in the crystalline cores, it has been suggested that the decay of the double bond does not result in the crosslinks

Narrativas sobre mujeres trans en España –desarrollada en 2010–, la cual estudió su presencia en textos académicos sobre prostitución en España, producidos entre los años 2000-2009. El análisis de contenido de 34 narrativas evidenció que las referencias a mujeres trans resulta escasa en ellas, aun siendo ellas quienes tienen mayor presencia en la prostitución, en proporción con las mujeres biológicas. Solo nueve textos mencionan la experiencia trans al interior de la prostitución y, entre estos, el asunto solo aparece asertivamente descrito cuando son las propias mujeres trans quienes escriben. AbstractThis paper shows the results of a qualitative research entitled: Hookers and Trans Women: Narratives about trans women in Spain. This study was developed in 2010 and it is based on presence of trans women in the academic texts of prostitution in Spain produced between 2000 and 2009. The content analysis of thirty four narratives showed that the references to in transsexual women in these texts were few, although they have more presence into prostitution, in relation to the biological women. Only nine texts show an experience of prostitution and among these, transexperience only is described assertively when transsexual women write the texts themselves.

The extent to which school district competitive food and beverage policies align with the 2010 Dietary Guidelines for Americans: implications for federal regulations.

Schneider, Linda M; Schermbeck, Rebecca M; Chriqui, Jamie F; Chaloupka, Frank J

2012-06-01

The Healthy, Hunger-Free Kids Act of 2010 authorized the Secretary of the US Department of Agriculture to establish science-based nutrition standards for competitive foods and beverages sold in school that are, at a minimum, aligned with the 2010 Dietary Guidelines for Americans (DGA), while still providing districts with discretion in regulating the competitive food and beverage environment. The objective of this study was to examine the extent to which district competitive food and beverage policies had specific and required limits aligned with 2010 DGA recommendations, and to inform US Department of Agriculture efforts as they develop competitive food and beverage standards. Competitive food and beverage policies were compiled for the 2009-2010 school year from a nationally representative sample of 622 districts. Each policy was double-coded for compliance with selected 2010 DGA recommendations (ie, restrictions on sugars, fats, trans fats, and sodium in foods and restrictions on regular soda, other sugar-sweetened beverages, and fat content of milk). Descriptive statistics were computed, clustered to account for the sample design, and weighted to account for districts nationwide. District nutrition policies were strongest for elementary schools. Nationwide, content of foods and soda availability were more commonly addressed. Areas that require attention include stronger nutrition standards at the secondary level, limits on trans fats, sodium, sugar-sweetened beverages other than soda, and fat content of milk, and greater availability of produce and whole grains at all sale locations.

To evaluate early visual rehabilitation, post-operative pain, epithelial healing and haze after transepithelial photorefractive keratectomy (TransPRK) using the SmartPulseTechnology (SPT) of Schwind Amaris (Schwind eye-tech-solutions GmbH, Kleinostheim, Germany). This was a retrospective comparative evaluation of a cohort of myopic patients undergoing TransPRK with SPT (group 1), with one matched control group that underwent conventional TransPRK (group 2). All cases had a 6-month post-operative follow-up including visual acuity and slit-lamp examination. Subjective evaluation of pain was recorded post-operatively. 49 eyes of 25 patients in group 1 and 40 eyes of 20 patients in group 2 were enrolled. The patients' visual rehabilitation was significantly faster in group 1, one day and one week post-operatively (P0.05). TransPRK using SPT provides promising results in the early post-operative period. Visual rehabilitation, re-epithelialization and pain were faster in the early post-operative period in group 1 in comparison with group 2. Haze formation was not significantly different between the two groups; however, it was consistently less in group 1. Copyright © 2016 British Contact Lens Association. Published by Elsevier Ltd.

TransForm: TransAlta 2000 annual report

International Nuclear Information System (INIS)

2001-01-01

Financial information from TransAlta Corp. was presented along with a review of their operations throughout 2000 and a summary of the how the electric utility is doing in terms of power generation, independent power producers, transmission and energy marketing. The utility has changed from a regulated vertically integrated utility into one of Canada's largest non-regulated electric power generators. The utility sold its retail businesses in Alberta and New Zealand and now focuses on coal and hydro generation, gas generation, high-voltage transmission and energy marketing. The newly constructed Centralia, Washington generation facility was brought on line with 1,340 MW in May 2000, on time and on budget. This was the platform to diversify their generation into the United States. The utility reported a solid financial year with $177.9 million in earnings from continuing operations, an 83 per cent increase from 1999, driven mostly by the results of Centralia and power marketing and trading businesses. A financial loss was suffered when the Wabamum power plant in Alberta was shut down for several months to repair a boiler. The utility made excellent progress toward their goal of 15,000 megawatts by 2005 by starting with the construction of what will be one of Canada's largest cogeneration facilities at Sarnia, Ontario. TransAlta also commissioned a 360 MW cogeneration facility at Poplar Creek at Suncor's Fort McMurray oil sand facility. TransAlta also has an excellent track record in developing power generation projects internationally. refs., tabs., figs

TransCanada PipeLines Limited 1998 annual report : TransCanada energy solutions

International Nuclear Information System (INIS)

1999-01-01

Financial information from TransCanada PipeLines Limited and a review of the company's 1998 operations was made available for the benefit of shareholders. TransCanada's pipeline system transports natural gas and crude oil from Western Canada Sedimentary Basin to North America's major energy markets. Net earnings from continuing operations for 1998, before unusual charges, were $575 million ($ 355 million after unusual charges) compared to $522 million for 1997. Solid performances from the energy transmission and international business, when compared to 1997, were more than offset by a decreased contribution from energy processing. TransCanada recorded integration costs of $166 million, after tax, related to the merger with NOVA in 1998, which was the major operational accomplishment during the year, creating a seamless economic energy delivery, processing and marketing system from the wellhead to the market. tabs., figs

Comparative evaluation of capillary electrophoresis and high-performance liquid chromatography for the separation of cis-cis, cis-trans, and trans-trans isomers of atracurium besylate.

Atracurium besylate is a highly selective nondepolarizing neuromuscular blocking agent routinely used during anesthetic procedures. The commercial presentation of this drug is a mixture of positional isomers, cis-cis, cis-trans, and trans-trans. Reversed-phase high-performance liquid chromatography has been the technique of choice for the analysis of atracurium besylate formulations at the quality control laboratory of Núcleo de Desenvolvimento Cristália (São Paulo, Brazil), a local pharmaceutical company. HPLC analysis is usually conducted under gradient elution using acetonitrile/0.1 M phosphate buffer eluent mixture as mobile phase and an octadecyl silica (ODS)-packed column. The complete elution of the three isomers takes about 1 hr. In this work, an alternative capillary electrophoresis methodology was developed. The complete resolution of all three isomers was accomplished in about 13 min (+20 kV/72 cm, 211 nm direct detection) using a 60-mM phosphate buffer solution (pH 4) containing 20 mM beta-cyclodextrin and 4 M urea. The isomer ratio was found to be 59.1% cis-cis, 35.9% cis-trans, and 5.02% trans-trans (expected ratio: 59:35:6). Laudanosine, a major metabolite of atracurium besylate, was identified in two commercially available formulations, Tracur (Núcleo de Desenvolvimento Cristália) and Tracrium (Glaxo Wellcome, S.A., Rio de Janeiro, Brazil). Its concentration increases considerably during storage of the product, even if the product is stored at low temperatures.

The structural parameters, thermodynamic properties and vibrational frequencies of the optimised geometry of trans-3-(trans-4-imidazolyl)acrylic acid have been determined from B3LYP methods with 6-311++G(**) and cc-pVTZ basis sets. The effects of substituents (acrylyl group) on the imidazole vibrational frequencies are analysed. The vibrational frequencies of the fundamental modes of trans-3-(trans-4-imidazolyl)acrylic acid have been precisely assigned and analysed and the theoretical results are compared with the experimental vibrations. (1)H and (13)C NMR isotropic chemical shifts are calculated and the assignments made are compared with the experimental values. The energies of important MO's of the compound are also determined from DFT method. The total electron density and electrostatic potential of the compound are determined by natural bond orbital analysis. Various reactivity and selectivity descriptors such as chemical hardness, chemical potential, softness, electrophilicity, nucleophilicity and the appropriate local quantities employing natural population analysis (NPA) are calculated.

Pyrolytic products of smoked methamphetamine hydrochloride are well established. Among the various degradation products formed, trans-phenylpropene (trans-β-methylstyrene) is structurally similar to styrene analogues known to be bioactivated by CYP enzymes. In human liver microsomes, trans-phenylpropene was converted to the epoxide trans-phenylpropylene oxide (trans-2-methyl-3-phenyloxirane) and cinnamyl alcohol. Incubation of trans-phenylpropene with microsomes in the presence of enzyme-specific P450 enzyme inhibitors indicated the involvement of CYP2E1, CYP1A2, and CYP3A4 enzymes. Both (R,R)-phenylpropylene oxide and (S,S)-phenylpropylene oxide were formed in human liver microsomal preparations. Enantiomers of trans-phenylpropylene oxide were stereoselectively and regioselectively conjugated in a Phase II drug metabolism reaction catalyzed by human liver cytosolic enzymes consisting of conjugation with glutathione. The structure of the phenylpropylene oxide-glutathione adduct is consistent with nucleophilic ring-opening by attack at the benzylic carbon. Exposure of cultured C6 glial cells to (S,S)-phenylpropylene oxide produced a cytotoxic response in a concentration-dependent manner based on cell degeneration and death

Full Text Available To improve visual disturbance, optic nerve decompression can be performed via transcranial or tran-sphenoidal approaches. Although the surgical exposure in transcranial approach is favourable, yet the optic nerve's presence in the field may make it vulnerable to damage. Of fighty patients with different types of pituitary adenomas, 35 cases with medium-sized (1-3 cm tumors have been studied in a randomized clinical trial during a three year period, to compare the applicability of these approaches. While short hospital stay with better visual outcome was observed in fifteen trans-sphenoidal cases, in comparison to 20 trans-cranial cases, however the preoperative visual status and underlying disorders were similar in both groups. Decompressing the optic apparatus, trans-sphenoidally, seems beneficial, where there are no contraindications for the procedure in medium-sized pituitary adenomas

Reasons for decision in the matter of Trans Mountain Pipeline Inc. (formerly Terasen Pipelines (Trans Mountain) Inc.) : tariffs

In 2006 and 2007 Terasen Pipelines (Trans Mountain) Inc. (now Trans Mountain Pipeline Inc.) submitted a series of applications to the National Energy Board for revisions to the Trans Mountain Tariffs. They were filed in response to apportionment concerns on the Trans Mountain pipeline. Four of the applications involved pronounced and contentious changes to the capacity allocation procedures on the pipeline system. For ease of reference, the Board amalgamated its 4 decisions on these applications into a single document. A map of the Trans Mountain pipeline system as a whole was presented along with a detailed map indicating the delivery locations served by the system in the lower mainland of British Columbia and the state of Washington. The issues considered by the Board in each of these decisions included capacity allocation for Westridge Dock; capacity allocations to export destinations; common carriage requirements; and the need for creating a new barge subcategory. Relevant sections of the National Energy Board Act referred to in the decisions were highlighted. This document also listed the Trans Mountain Tariffs that have introduced notable revisions to the capacity allocation procedures on the system since September 2003. 16 refs., 2 figs., 3 appendices

Eckel, Robert H; Borra, Susan; Lichtenstein, Alice H; Yin-Piazza, Shirley Y

2007-04-24

A 2-day forum was convened to discuss the current status and future implications of reducing trans fatty acids without increasing saturated fats in the food supply while maintaining functionality and consumer acceptance of packaged, processed, and prepared foods. Attendees represented the agriculture and oilseed industry and oil processing, food manufacturing, food service, government, food technology, and health and nutrition disciplines. Presentations included food science behind fatty acid technology, the health science of dietary fatty acids, alternatives to trans fatty acids, and the use of alternatives in food manufacturing and food service. The reduction of trans fatty acids in the food supply is a complex issue involving interdependent and interrelated stakeholders. Actions to reduce trans fatty acids need to carefully consider both intended and unintended consequences related to nutrition and public health. The unintended consequence of greatest concern is that fats and oils high in saturated fats, instead of the healthier unsaturated fats, might be used to replace fats and oils with trans fatty acids. Many different options of alternative oils and fats to replace trans fatty acids are available or in development. Decisions on the use of these alternatives need to consider availability, health effects, research and development investments, reformulated food quality and taste, supply-chain management, operational modifications, consumer acceptance, and cost. The conference demonstrated the value of collaboration between the food industry and health and nutrition professionals, and this conference model should be used to address other food development, processing, and/or technology issues.

Becoming lesbian: Monique Wittig's queer-trans-feminism.

Science.gov (United States)

Henderson, Kevin

2018-04-03

Inspired by Lynne Huffer's queer feminist genealogy, this article explores queer-trans-feminism as a project that would bring together queer, feminist, and transgender theory and politics into a shared critical lineage. I suggest that Monique Wittig is a neglected thinker who could re-enliven connections and debates within queer, feminist, and trans theory and politics. Utilizing recent historiographies of queer and feminist theory, I imagine what it would mean to hold on to the figure of the lesbian as a figure for queer-trans-feminist politics rather than render the lesbian anachronistic. I then explore the implications of Wittig's notion that "lesbians are not women" for a queer-trans-feminism. I argue that Wittig's critique of the language of the social sciences offers queer-trans-feminist scholars a source for contemporary self-critique and coalition.

Sex steroids and genital surgery are known to affect sexual desire, but little research has focused on the effects of cross-sex hormone therapy and sex reassignment surgery on sexual desire in trans persons. This study aims to explore associations between sex reassignment therapy (SRT) and sexual desire in a large cohort of trans persons. A cross-sectional single specialized center study including 214 trans women (male-to-female trans persons) and 138 trans men (female-to-male trans persons). Questionnaires assessing demographics, medical history, frequency of sexual desire, hypoactive sexual desire disorder (HSDD), and treatment satisfaction. In retrospect, 62.4% of trans women reported a decrease in sexual desire after SRT. Seventy-three percent of trans women never or rarely experienced spontaneous and responsive sexual desire. A third reported associated personal or relational distress resulting in a prevalence of HSDD of 22%. Respondents who had undergone vaginoplasty experienced more spontaneous sexual desire compared with those who planned this surgery but had not yet undergone it (P = 0.03). In retrospect, the majority of trans men (71.0%) reported an increase in sexual desire after SRT. Thirty percent of trans men never or rarely felt sexual desire; 39.7% from time to time, and 30.6% often or always. Five percent of trans men met the criteria for HSDD. Trans men who were less satisfied with the phalloplasty had a higher prevalence of HSDD (P = 0.02). Trans persons who were more satisfied with the hormonal therapy had a lower prevalence of HSDD (P = 0.02). HSDD was more prevalent in trans women compared with trans men. The majority of trans women reported a decrease in sexual desire after SRT, whereas the opposite was observed in trans men. Our results show a significant sexual impact of surgical interventions and both hormonal and surgical treatment satisfaction on the sexual desire in trans persons. © 2013 International Society for Sexual

Starch plus sunflower oil addition to the diet of dry dairy cows results in a trans-11 to trans-10 shift of biohydrogenation.

Trans fatty acids (FA), exhibit different biological properties. Among them, cis-9,trans-11 conjugated linoleic acid has some interesting putative health properties, whereas trans-10,cis-12 conjugated linoleic acid has negative effects on cow milk fat production and would negatively affect human health. In high-yielding dairy cows, a shift from trans-11 to trans-10 pathway of biohydrogenation (BH) can occur in the rumen of cows receiving high-concentrate diets, especially when the diet is supplemented with unsaturated fat sources. To study this shift, 4 rumen-fistulated nonlactating Holstein cows were assigned to a 4×4 Latin square design with 4 different diets during 4 periods. Cows received 12 kg of dry matter per day of 4 diets based on corn silage during 4 successive periods: a control diet (22% starch, diet supplemented with wheat plus barley (35% starch, diet supplemented with 5% of sunflower oil (20% starch, 7.6% crude fat), and a high-starch plus sunflower oil diet (33% starch, 7.3% crude fat). Five hours after feeding, proportions of trans-11 BH isomers greatly increased in the rumen content with the addition of sunflower oil, without change in ruminal pH compared with the control diet. Addition of starch to the control diet had no effect on BH pathways but decreased ruminal pH. The addition of a large amount of starch in association with sunflower oil increased trans-10 FA at the expense of trans-11 FA in the rumen content, revealing a trans-11 to trans-10 shift. Interestingly, with this latter diet, ruminal pH did not change compared with a single addition of starch. This trans-11 to trans-10 shift occurred progressively, after a decrease in the proportion of trans-11 FA in the rumen, suggesting that this shift could result from a dysbiosis in the rumen in favor of trans-10-producing bacteria at the expense of those producing trans-11 or a modification of bacterial activities.

Trans fat is a unsaturated fatty acid with trans configuration and separated double bonds. Analytical methods have been introduced to analyze trans fat content in foods including infrared (IR) spectroscopy, gas chromatography (GC), Fourier transform-infrared (FT-IR) spectroscopy, reverses-phase silver ion high performance liquid chromatography, and silver nitrate thin layer chromatography. Currently, FT-IR spectroscopy and GC are mostly used methods. Trans fat content in 6 vegetable oils were analyzed and processing effects including baking, stir-frying, pan-frying, and frying on the formation of trans fat in corn oil was evaluated by GC. Among tested vegetable oils, corn oil has 0.25 g trans fat/100 g, whereas other oils including rapeseed, soybean, olive, perilla, and sesame oils did not have detectable amount of trans fat content. Among cooking methods, stir-frying increased trans fat in corn oil whereas baking, pan-frying, and frying procedures did not make changes in trans fat content compared to untreated corn oils. However, the trans fat content was so low and food label can be declared as ‘0’ trans based on the regulation of Ministry of Food ad Drug Safety (MFDS) (edible oil). PMID:26483890

This article explores some of the challenges faced by trans and gender diverse (TGD) individuals who not only are attempting to access trans-affirmative care, but who are also members of the very profession from which they are seeking services. The authors explore challenges related to finding supervision, accessing care for assessment services, and finding a provider for personal counseling. With each example, the authors unpack the challenges and also address the implications for training for all involved. Based on these challenges that TGD psychologists and trainees face in attempting to access care, the authors provide recommendations related to trans-affirmative training for psychologists. © 2017 Wiley Periodicals, Inc.

Metabolism of trans, trans-muconaldehyde, a cytotoxic metabolite of benzene, in mouse liver by alcohol dehydrogenase Adh1 and aldehyde reductase AKR1A4

2006-01-01

The reductive metabolism of trans, trans-muconaldehyde, a cytotoxic metabolite of benzene, was studied in mouse liver. Using an HPLC-based stopped assay, the primary reduced metabolite was identified as 6-hydroxy-trans, trans-2,4-hexadienal (OH/CHO) and the secondary metabolite as 1,6-dihydroxy-trans, trans-2,4-hexadiene (OH/OH). The main enzymes responsible for the highest levels of reductase activity towards trans, trans-muconaldehyde were purified from mouse liver soluble fraction first by Q-sepharose chromatography followed by either blue or red dye affinity chromatography. In mouse liver, trans, trans-muconaldehyde is predominantly reduced by an NADH-dependent enzyme, which was identified as alcohol dehydrogenase (Adh1). Kinetic constants obtained for trans, trans-muconaldehyde with the native Adh1 enzyme showed a V max of 2141 ± 500 nmol/min/mg and a K m of 11 ± 4 μM. This enzyme was inhibited by pyrazole with a K I of 3.1 ± 0.57 μM. Other fractions were found to contain muconaldehyde reductase activity independent of Adh1, and one enzyme was identified as the NADPH-dependent aldehyde reductase AKR1A4. This showed a V max of 115 nmol/min/mg and a K m of 15 ± 2 μM and was not inhibited by pyrazole

Trans fats in New Zealand: time for labelling regulations?

Science.gov (United States)

Gladding, Patrick; Benatar, Jocelyne R

2007-11-09

Trans fats (trans fatty acids) are commonly used for deep frying in restaurants and in the fast food, snack food, fried food, and baked goods industries, often to extend the shelf life of foods. However they are widely considered to be harmful to health. Trans fats were banned in New York City restaurants from 1 July 2007, and there is growing vocal opposition to trans fats in the European Union. Denmark became the first country, in March 2003, to introduce laws regulating the content of trans fats in food (maximum of 2% of edible fats and oils). What are trans fats, what harm do they cause, and should New Zealand also consider imposing mandatory regulations on their use in food? This article explores the issues.

Physics of Trans-Planckian Gravity

CERN Document Server

Dvali, Gia; Germani, Cristiano

2011-01-01

We study aspects of the phenomenon of gravitational UV-self-completeness and its implications for deformations of Einstein gravity. In a ghost-free theory flowing to Einstein gravity in the IR trans-Planckian propagating quantum degrees of freedom cannot exist. The only physical meaning of a trans-Planckian pole is the one of a classical state (Black Hole) which is fully described by the light IR quantum degrees of freedom and gives exponentially-suppressed contributions to virtual processes. In this sense Einstein gravity is UV self-complete, although not Wilsonian. We show that this UV/IR correspondence puts a severe constraint on any attempt of conventional Wilsonian UV-completion of trans-Planckian gravity. In particular, there is no well-defined energy domain in which gravity could become asymptotically weak or safe.

Full Text Available Phenolic acids and their derivatives found in nature are well-known for their potential biological activity. In this study, two amides derived from trans-caffeic/ferulic acid and dopamine were synthesized and characterized by Fourier-transform infrared spectroscopy (FTIR, mass spectrometry, proton and carbon-13 nuclear magnetic resonance spectroscopy. The compounds were tested for the inhibition of acetylcholinesterase (AChE from Electrophorus electricus and for antioxidant activity by scavenging 2,2-diphenyl-1-pycrylhydrazyl free radical (DPPH• and 2,2′-azinobis(3-ethylbenzothiazoline-6-sulphonic acid radical cation (ABTS•+, reducing ferric ions, and ferrous ions chelation. N-trans-Feruloyldopamine displayed the highest inhibitory effect on AChE with half-maximal inhibitory concentration (IC50 values of 8.52 μM. In addition, an in silico study was done to determine the most favorable AChE cluster with the synthesized compounds. Further, these clusters were investigated for binding positions at the lowest free binding energy. Both synthesized hydroxycinnamates were found to be better antioxidants than the parent acids in in vitro tests applied. N-trans-Caffeoyldopamine showed the best antioxidant activity in the three tested methods—against non-biological stable free radicals IC50 5.95 μM for DPPH•, 0.24 μM for the ABTS•+ method, and for reducing power (ascorbic acid equivalent (AAE 822.45 μmol/mmol—while for chelation activity against Fe2+ ions N-trans-feruloyldopamine had slightly better antioxidant activity (IC50 3.17 mM.

The second part of the paper, 'Trans Studies: In-Between Feminist and Queer Theory?', places transgender studies into an academic context by referring to the theoretical framework provided by trans theorists Stryker, Stone, and Ranck who unanimously claim that transgender studies should have a place of its own within the academia and that trans theory should solely be written by transsexuals. These ideas are applied in the interpretation of Lochhead's story 'Not Changed' in the third segment of the paper.

Przybylski, Oman; Aladedunye, Felix A

2012-01-01

An investigation was completed to determine how typical cooking procedures used in food preparation, such as baking and stir-frying, affect trans fats formation. Canola oil was used as the main fat ingredient. Zucchini cake and gingersnap cookies were baked at 180o C and 200o C, while stir-fried chicken was prepared at 200o C and 275o C. The lipids from the food were extracted following the Folch procedure, and analyzed for trans fatty acids according to ISO official method 15304. Minimal changes were observed in the amount of trans fats during baking. Application of extreme temperatures during baking, which caused carbonization of the outer layer of products, yielded an insignificant increase in the amount of trans isomers. As with baking, stir-frying did not result in significant isomerization of the fatty acids, even when the oil was heated to 275o C and smoking heavily before the food was placed in it. Irrespective of the cooking procedure, linolenic acid was the most prone to isomerization with the highest amount of trans isomers formation. Baking and stir-frying at normal and/or extreme temperatures do not significantly affect the amounts of trans fats. Likewise, heating oil to the smoking point during stir-frying may decrease the amount of polyunsaturated fatty acids because of oxidative degradation.

Wojnicki, F H E; Charny, G; Corwin, R L W

Studies from this and another laboratory involving an animal model of binge-type behavior have used vegetable shortening containing trans-fats. Due to reformulations by vegetable shortening manufacturers to remove trans-fats from their products, only trans-fat-free shortenings are now available. The goal of the present study was to assess binge-type behavior in rats with trans-fat and trans-free vegetable shortening. Trans-fat-free shortening was provided to three different groups of non-food-deprived male Sprague Dawley rats on different schedules of access: continuous access (24 h/day-7 days/week), daily access (1 h every day), and intermittent access (1 h on Mondays, Wednesdays, Fridays). Trans-fat shortening was provided to a fourth group on the intermittent access schedule. A fifth group had no shortening access (chow only). Both intermittent groups (trans-fat-free and trans-fat) consumed significantly more shortening during the 1-h period of availability than did the daily group, and there was no difference in shortening intakes between the intermittent groups. These results are identical to previous reports of binge-type behavior in rats using this model. Thus, binge-type behavior in the present behavioral model depends upon the schedule of access, not the presence of trans-fats in the shortening.

Cis-trans photoisomerization of abscisic acid

Brabham, D.E.; Biggs, R.H.

1981-01-01

An important regulator of numerous physiological processes in higher plants is abscisic acid (ABA), which is photoisomerized from the more biologically active cis isomer to the nearly inactive trans isomer by natural sunlight. It is possible that this photoisomerization is a UV control mechanism in functions regulated by ABA. The quantum yields of both the cis to trans and trans to cis photoisomerizations were measured under various conditions of pH and oxygen concentration at room temperature. The yield for photoisomerization of cis-ABA ranged from 0.25 at pH 3.0 to 0.11 at pH 7.0. Oxygen partially quenched the process. The quantum yield varied only slightly with wavelength. The quantum yield of photolysis of cis-ABA was reported for pH 3.0 as 0.06. This yield also varied slightly with wavelength and was relatively insensitive to oxygen. This relatively high yield explains the loss of potency of ABA during UV irradiation. Phosphorescence of cis- and trans-ABA was observed in methanol at 77 K. Onset of the emission was at 350 nm. The emission spectra were the same for both isomers. From these results a mechanism of UV action on plants based on the photoisomerization of the inactive trans-ABA to the biologically active cis isomer is proposed. (author)

trans fatty acids are associated to several health disorders, as ischemic heart disease or diabetes mellitus. to assess the content of trans fatty acids in products in Spain, and the percentage of trans fatty acids respecting total fatty acids. 443 food products were acquired in Spain, and they were classified into groups. The content in fatty acids was analyzed using gas chromatography. Estimates of central tendency and variability of the content of trans fatty acids in each food group were computed (in g of trans fatty acids/100 g of product). The percentage of trans fatty acids respecting total fatty acids was calculated in each group. 443 products were grouped into 42 groups. Median of trans fatty acids was less than 0.55 g / 100 g of product in all groups except one. 83 % of groups had less than 2 % of trans fatty acids, and 71 % of groups had less than 1 %. the content of trans fatty acids in Spain is low, and it currently doesn't play a public health problem.

Peel Region TransHelp's experience

Energy Technology Data Exchange (ETDEWEB)

NONE

2009-09-15

TransHelp was founded in the Peel Region of Ontario in 1981 to provide paratransit service to individuals unable to use conventional transit. The TransHelp vehicle fleet consists of 40 buses that make over 220,000 one way trips annually. Each vehicle has a typical life span of between 375,000 and 425,000 km. TransHelp vehicles spend much of their time idling in emissions-sensitive areas, such as outside hospitals. In order to reduce fuel costs, TransHelp adopted the use of propane to fuel its vehicles. However, difficulties were experienced with this technology, particularly on V-10 engines where increased maintenance was a problem. SFI Technologies Inc. provided a solution with their SEQUIN System which allows seamless transitioning between gasoline and propane under all conditions without any operator involvement in fuel selection. The technology favours propane as the fuel of choice and automatically switches between propane and gasoline based on the ideal conditions at the time of operation. The technology has received certification from the Environmental Protection Agency in the United States and the Canadian Standards Association. The use of the SEQUIN System has proven to successful for TransHelp. It has allowed the use of propane to be continued, meaning that vehicle emissions are greatly reduced relative to gasoline or diesel fuelled vehicles. TransHelp has realized a fuel savings of 15-20 per cent over gasoline and receives an additional federal transit rebate of 15 per cent for the conversion cost.

Trans Women Doing Sex in San Francisco.

This research investigates the sexuality of trans women (individuals who were assigned male status at birth who currently identify as women), by focusing on the "bodily techniques" (Crossley, 2006) they use in "doing" sexuality. The "doing sexuality" framework not only is modeled after the "doing gender" approach of West and Zimmerman (1987), but also utilizes the idea of "sexual embodiment" to emphasize the agency of trans women as they conceptualize and organize their sexuality in a socially recognized way. This is often difficult as they confront discrimination from medical and legal professionals as well as intimate partners who may find it difficult to adapt to the trans woman's atypical body and conception of gender. However, with a study group of 25 trans women from San Francisco, we found the study participants to be adept at overcoming such hurdles and developing techniques to "do" their sexuality. At the same time, we found trans women's agency constrained by the erotic habitus (Green, 2008) of the wider society. The interplay between innovation and cultural tradition provides an opportunity to fashion a more general model of "doing" sexuality.

Transformer based Z-source (trans-Z-source) inverters are recently proposed by extending the traditional Z-source inverter with higher buck-boost capability as well as reducing the passive components at the same time. Multi-Level Z-source inverters are single-stage topological solutions used...... for buck-boost energy conversion with all the favourable advantages of multi-level switching retained. This paper presents three-level trans-Z-source Neutral Point Clamped (NPC) inverter topology, which achieves both the advantages of trans-Z-source and three-level NPC inverter configuration. With proper...... modulation scheme, the three-level trans-Z-source inverter can function with minimum of six device commutations per half carrier cycle (same as the traditional buck NPC inverter), while maintaining to produce the designed volt-sec average and inductive voltage boosting at ac output terminals.

Cheng, Xing; An, Ping; Li, Shujin; Zhou, Liping

2018-04-26

In the present study, the repair activity of trans-resveratrol toward 2'-deoxyguanosine (dGuo) radicals in polar and nonpolar solvents was studied using density functional theory. The hydrogen transfer/proton coupled electron transfer and single electron transfer (SET) mechanisms between trans-resveratrol and dGuo-radicals were considered. Taking into consideration the molar fraction of neutral trans-resveratrol (ROH) and anionic trans-resveratrol (RO - ), the overall rate constants for repairing dGuo-radicals by trans-resveratrol are 9.94 × 10 8 and 2.01 × 10 9 dm 3 mol -1 s -1 in polar and nonpolar solvents, respectively, and the overall rate constant of repairing cation radical (dGuo •+ ) by trans-resveratrol via an SET mechanism is 7.17 × 10 9 dm 3 mol -1 s -1 . The repair activity of RO - toward dGuo-radicals is better than that of ROH, but the repair activity of ROH toward dGuo •+ is better than that of RO - . Unfortunately, neither ROH nor RO - can repair the 2'-deoxyribose radicals of dGuo. It can therefore be concluded that trans-resveratrol is an effective antioxidant for repairing base radicals of dGuo and dGuo •+ . The study can help us understand the repair activity of trans-resveratrol toward dGuo radicals.

The importance of trans-generational effects in Lepidoptera.

2016-10-01

The importance of trans-generational effects in shaping an individuals' phenotype and fitness, and consequently even impacting population dynamics is increasingly apparent. Most of the research on trans-generational effects still focuses on plants, mammals, and birds. In the past few years, however, increasing number of studies, especially on maternal effects, have highlighted their importance also in many insect systems. Lepidoptera, specifically butterflies, have been used as model systems for studying the role of phenotypic plasticity within generations. As ectotherms, they are highly sensitive to environmental variation, and indeed many butterflies show adaptive phenotypic plasticity in response to environmental conditions. Here, we synthesize what is known about trans-generational effects in Lepidoptera, compile evidence for different environmental cues that are important drivers of trans-generational effects, and point out which offspring traits are mainly impacted. Finally, we emphasize directions for future research that are needed for better understanding of the adaptive nature of trans-generational effects in Lepidoptera in particular, but potentially also in other organisms.

2014-10-01

Full Text Available Studies linking high trans-fat diets to coronary heart disease (CHD have prompted the need to regulate, limit, or completely ban trans-fat from all commercial food products, including fast foods. Many U.S. fast food chains now claim that their food items, particularly French fries, have "no trans-fat". In a previous study, our lab tested the validity of trans-fat claims made by several popular fast food restaurants by experimentally determining the %trans-fat in oil extracted from fast food French fries. In some cases, the trans-fat content was nearly twice as high as the amount reported by the restaurant in their literature. Long John Silver's, for example, reported a trans-fat content of 25% for their French fries, while our lab actually found over 40% trans-fat. The purpose of this study is to broaden our study of Long John Silver's trans-fat claims by analyzing a variety of their food items and comparing our findings with the %trans-fat reported by the restaurant literature (nutrition fact tables. Variable Filter Array (VFA IR spectroscopy was used to assess the trans-fat content of oil extracted from food samples. Our preliminary findings suggest that nearly every food item under study contained considerably more trans-fat than the amount reported in the restaurant’s literature.

Chem. 33 (1982) 443] it was discovered that doped trans-polyacetylene (CH) x , a one-dimensional (1D) conjugated polymer, exhibits electrical conductivity. In this work we show that an asymmetrically doped 1D trans-polymer has non-conventional properties, as compared to symmetrically doped systems. Depending on the level of asymmetry between the chemical potentials of the two involved fermionic species, the polymer can be in a partially or fully spin polarized state. Some possible experimental consequences of doped 1D trans-polymers used as 1D organic polarized conductors are discussed.

Many in vitro studies demonstrated significant biological effects of trans-resveratrol. Thus, understanding the rate of intestinal absorption and metabolization in vivo of trans-resveratrol is the prerequisite to evaluate its potential health impact. Bioavailability studies mainly in animals or in humans using the pure compound at very high doses were performed. In this work, trans-resveratrol bioavailability from a moderate consumption of red wine in 25 healthy humans has been studied by three different experiments. The wine ingestion was associated to three different dietary approaches: fasting, a standard meal, a meal with high and low amount of lipids. Trans-resveratrol 3- and 4'-glucuronides were synthesized, purified, and characterized as pure standards. Bioavailability data were obtained by measuring the concentration of free, 3-glucuronide and 4'-glucuronide trans-resveratrol by high-performance liquid chromatography (HPLC), both with ultraviolet (UV) and mass spectrometry (MS) detection, in serum samples taken at different times after red wine administration. Free trans-resveratrol was found, in trace amounts, only in some serum samples collected 30 min after red wine ingestion while after longer times resveratrol glucuronides predominated. Trans-resveratrol bioavailability was shown to be independent from the meal or its lipid content. The finding in human serum of trans-resveratrol glucuronides, rather than the free form of the compound, with a high interindividual variability, raises some doubts about the health effects of dietary resveratrol consumption and suggests that the benefits associated to red wine consumption could be probably due to the whole antioxidant pool present in red wine.

The inverse-trans-influence in tetravalent lanthanide and actinide bis(carbene) complexes

Across the periodic table the trans-influence operates, whereby tightly bonded ligands selectively lengthen mutually trans metal-ligand bonds. Conversely, in high oxidation state actinide complexes the inverse-trans-influence operates, where normally cis strongly donating ligands instead reside trans and actually reinforce each other. However, because the inverse-trans-influence is restricted to high-valent actinyls and a few uranium(V/VI) complexes, it has had limited scope in an area with few unifying rules. Here we report tetravalent cerium, uranium and thorium bis(carbene) complexes with trans C=M=C cores where experimental and theoretical data suggest the presence of an inverse-trans-influence. Studies of hypothetical praseodymium(IV) and terbium(IV) analogues suggest the inverse-trans-influence may extend to these ions but it also diminishes significantly as the 4f orbitals are populated. This work suggests that the inverse-trans-influence may occur beyond high oxidation state 5f metals and hence could encompass mid-range oxidation state actinides and lanthanides. Thus, the inverse-trans-influence might be a more general f-block principle.

Physics of trans-Planckian gravity

2011-01-01

We study the field theoretical description of a generic theory of gravity flowing to Einstein general relativity in IR. We prove that, if ghost-free, in the weakly-coupled regime such a theory can never become weaker than general relativity. Using this fact, as a by-product, we suggest that in a ghost-free theory of gravity trans-Planckian propagating quantum degrees of freedom cannot exist. The only physical meaning of a trans-Planckian pole is the one of a classical state (black hole) which is described by the light IR quantum degrees of freedom and gives exponentially-suppressed contributions to virtual processes. In this picture Einstein gravity is UV self-complete, although not Wilsonian, and sub-Planckian distances are unobservable in any healthy theory of gravity. We then finally show that this UV/IR correspondence puts a severe constraint on any attempt of conventional Wilsonian UV-completion of trans-Planckian gravity. Specifically, there is no well-defined energy domain in which gravity could become asymptotically weak or safe.

Dietary trans-fats are strongly associated with heart disease. However, the capacity for the tissues of the body, and specifically the heart, to take up trans-fats is unknown. It is also unknown if different trans-fats have different uptake capacities in the heart and other tissues of the body. Diets of low-density lipoprotein receptor-deficient mice were supplemented for 14weeks with foods that contained 1.5% of the trans-fat elaidic acid or vaccenic acid. Tissues were extracted and frozen in liquid nitrogen, and then lipids were analyzed by gas chromatography for fatty acid content. Isolated cardiomyocytes were also exposed to elaidic or vaccenic acid in cell culture media for 24h. Dietary supplementation with vaccenic or elaidic acid resulted in a 20-fold higher accumulation of these TFAs in fat deposits in the body in comparison to liver. Liver tissue accumulated about twice as much per gram tissue as heart. Similar quantities of both elaidic acid and vaccenic acid were taken up by the tissues. Isolated cardiomyocytes exhibited an unusually large uptake of trans-fat, and this was dependent upon both the concentration and duration of exposure to the trans-fats but not upon the type of trans-fat. Expression levels of CD36 and FATP4 were not significantly changed during dietary interventions or exposure of cells to trans-fats. We conclude that fat, liver and heart (including cardiomyocytes) are all capable of accumulating trans-fat in response to dietary supplementation without changes in fatty acid transport protein expression.

Manuel Spannagl

2016-03-01

Full Text Available The genome sequences of many important Triticeae species, including bread wheat ( L. and barley ( L., remained uncharacterized for a long time because their high repeat content, large sizes, and polyploidy. As a result of improvements in sequencing technologies and novel analyses strategies, several of these have recently been deciphered. These efforts have generated new insights into Triticeae biology and genome organization and have important implications for downstream usage by breeders, experimental biologists, and comparative genomicists. transPLANT ( is an EU-funded project aimed at constructing hardware, software, and data infrastructure for genome-scale research in the life sciences. Since the Triticeae data are intrinsically complex, heterogenous, and distributed, the transPLANT consortium has undertaken efforts to develop common data formats and tools that enable the exchange and integration of data from distributed resources. Here we present an overview of the individual Triticeae genome resources hosted by transPLANT partners, introduce the objectives of transPLANT, and outline common developments and interfaces supporting integrated data access.

Dietary trans-fatty acids and metabolic syndrome

Directory of Open Access Journals (Sweden)

Zdzisław Kochan

2010-12-01

Full Text Available Trans-fatty acids (TFAs, products of partial hydrogenation of vegetable oils, have become more prevalent in our diet since the 1960s, when they replaced animal fats. TFAs also occur naturally in meat and dairy products from ruminants. There is growing evidence that dietary trans-fatty acids may increase the risk of metabolic syndrome. Several studies have demonstrated adverse effects of TFAs on plasma lipids and lipoproteins. In dietary trials, trans-fatty acids have been shown to raise the total cholesterol/HDL cholesterol ratio and Lp(a levels in blood. Moreover, a high intake of TFAs has been associated with an increased risk of coronary heart disease. Prospective cohort studies have shown that dietary trans-fatty acids promote abdominal obesity and weight gain. In addition, it appears that TFA consumption may be associated with the development of insulin resistance and type 2 diabetes. The documented adverse health effects of TFAs emphasise the importance of efforts to reduce the content of partially hydrogenated vegetable oils in foods.

The evolutionary landscape of intergenic trans-splicing events in insects

Kong, Yimeng; Zhou, Hongxia; Yu, Yao; Chen, Longxian; Hao, Pei; Li, Xuan

2015-01-01

To explore the landscape of intergenic trans-splicing events and characterize their functions and evolutionary dynamics, we conduct a mega-data study of a phylogeny containing eight species across five orders of class Insecta, a model system spanning 400 million years of evolution. A total of 1,627 trans-splicing events involving 2,199 genes are identified, accounting for 1.58% of the total genes. Homology analysis reveals that mod(mdg4)-like trans-splicing is the only conserved event that is consistently observed in multiple species across two orders, which represents a unique case of functional diversification involving trans-splicing. Thus, evolutionarily its potential for generating proteins with novel function is not broadly utilized by insects. Furthermore, 146 non-mod trans-spliced transcripts are found to resemble canonical genes from different species. Trans-splicing preserving the function of ‘breakup' genes may serve as a general mechanism for relaxing the constraints on gene structure, with profound implications for the evolution of genes and genomes.

Sandra Lilyana

2017-07-01

Full Text Available The study is about a close look at Conrad's trans-racial romance related to the Victorian period. Trans-racial love between white men and non-white women becomes a popular theme in the early works of Josep Conrad, a famous writer of the late Victorian period. Using a closely technical reading in the three of Conrad's works Lord Jim, Almayer's Folly, and An Outcast of the Island, we can show that such a trans-racial romance is not merely meant for appreciating equivalence. In turn, the trans-racial romance of Conrad's can be understood as the reflection of the Western colonization on the East where the white men take a role as subjects who had dominately explored while the non-white women as objects who are passively being explored. Key words: colonization, race, romance plot, subject, object, and dominance

Technical aspects of trans reduction in margarines

Van Duijn Gerrit

2000-01-01

Full Text Available The opinion of nutritional science on the effect of trans fatty acids on blood cholesterol has drastically changed during the last decade. As a reaction to these new findings, the European margarine industry decided in the mid nineties to eliminate trans containing components from their margarine fat phase compositions. This excluded practically the use of partially hydrogenated oils and fats. Trans-free margarines have been introduced with optimised fat crystal structures stabilising a maximum of water in oil emulsion with a minimum of solid fat phase. These fat crystal structures are formed by fat phase components obtained from interesterification and/or fractionation of non-hydrogenated and/or fully hydrogenated feedstocks.

Buku, A.; Faulstich, H.; Wieland, T.; Dabrowski, J.

1980-01-01

Among the four possible stereoisomers of 3,4-dihydroxy-L-proline,2,3-trans-3,4-trans-3,4-dihydroxy-L-proline (IV) had not been found in nature previously. It has now been detected as a component of virotoxins, toxic peptides of Amanita virosa mushrooms. Because periodate failed to effect an oxidative glycol splitting reaction, the two hydroxyl groups in positions 3 and 4 were expected to be in a trans configuration. Furthermore, the formation of a 4-lactone on treatment with acids pointed to the carboxyl group and the hydroxyl group at position 4 being in a cis configuration. These results are in agreement with structure IV only. Final proof for structure IV was given by NMR spectroscopy and direct comparison with the 2,3-cis-3,4-trans-3,4-dihydroxy-L-proline isomer.

METHODS: Industrialized food (creamy margarine A and B, plant sterol margarine, stuffed sweet biscuit, salty biscuit without stuffing, French fried potatoes and a burger lunch from a multinational chain of "fast food" all with the allegation of 0% trans fat content were purchased in commercial points and analyzed by gas chromatography. RESULTS: Despite the reduction in trans fatty acid amounts, analyzed foods contained large concentrations of saturated fats

Design of Trypanosoma rangeli sialidase mutants with improved trans-sialidase activity.

Directory of Open Access Journals (Sweden)

Christian Nyffenegger

Full Text Available A sialidase (EC 3.2.1.18 from the non-pathogenic Trypanosoma rangeli, TrSA, has been shown to exert trans-sialidase activity after mutation of five specific amino acids in the active site (M96V, A98P, S120Y, G249Y, Q284P to form the so-called TrSA5mut enzyme. By computational and hypothesis driven approaches additional mutations enhancing the trans-sialidase activity have been suggested. In the present work, we made a systematic combination of these mutations leading to seven new variants of the T. rangeli sialidase, having 6-16 targeted amino acid mutations. The resulting enzyme variants were analyzed via kinetics for their ability to carry out trans-sialidase reaction using CGMP and D-lactose as substrates. The sialidase variants with 15 and 16 mutations, respectively, exhibited significantly improved trans-sialidase activity for D-lactose sialylation. Our results corroborate, that computational studies of trans-glycosylation can be a valuable input in the design of novel trans-glycosidases, but also highlight the importance of experimental validation in order to assess the performance. In conclusion, two of the seven mutants displayed a dramatic switch in specificity from hydrolysis towards trans-sialylation and constitute the most potent trans-sialidase mutants of TrSA described in literature to date.

Interesterificação química: alternativa para obtenção de gorduras zero trans Chemical interresterification: alternative to production of zero trans fats

2007-10-01

Full Text Available The function of lipids in human nutrition has been intensively debated in the last decade.This context reinforces the concern about controlling the trans fat ingestion, due to its negative implications on health. Interesterification provides an important alternative to modify the consistency of oils and fats without causing formation of trans isomers. This article reports research done towards production of zero trans fats by chemical interesterification, for different industrial purposes. Aspects related to the effect of trans fats on diet, their impact on health and modifications in Brazilian legislation are also covered.

Thomas George

2008-11-01

Full Text Available Abstract Background Trans-mitral Doppler produces complex patterns with a great deal of variability. There are several confusing numerical measures and indices to study these patterns. However trans-mitral Doppler produces readymade data visualization by pattern generation which could be interpreted by pattern analysis. By following a systematic approach we could create an order and use this tool to study cardiac function. Presentation of the hypothesis In this new approach we eliminate the variables and apply pattern recognition as the main criterion of study. Proper terminologies are also devised to avoid confusion. In this way we can get some meaningful information. Testing the hypothesis Trans-mitral Doppler should be seen as patterns rather than the amplitude. The hypothesis can be proven by logical deduction, extrapolation and elimination of variables. Trans-mitral flow is also analyzed vis-à-vis the Starling's Law applied to the left atrium. Implications of the hypothesis Trans-mitral Doppler patterns are not just useful for evaluating diastolic function. They are also useful to evaluate systolic function. By following this schema we could get useful diagnostic information and therapeutic options using simple pattern recognition with minimal measurements. This simplified but practical approach will be useful in day to day clinical practice and help in understanding cardiac function better. This will also standardize research and improve communication.

Full Text Available Craniopharyngiomas have been by and large excised by the transcranial route. Since 1982, 11 patients have been operated by the traus-sphensidal route in the department. The clinical features with which they were presented, diagnostic investigations, details of surgical procedures and follow-up analysis is being presented here. A retrospective study of radiological investigation was done to determine the features that help decide the choice of surgical approach to these lesions. Only lesions that were primarily intrasellar, cystic and those that expanded the sella could be treated by the trans-sphenoidal route. Associated suprasellar extensions could also be removed. Predominantly calcified or firm, fleshy tumours lent themselves poorly to removal by the trans-sphenoidal route.

Gordon, Danny; Pratama, Mario Prajna

2017-01-01

This work sought to document how Indonesian trans* FtM persons experienced discrimination across the interlinked domains of social networks, religious and educational institutions, employment and the workplace, and health care institutions. Objectives were (1) to map the discrimination experienced by trans* FtM individuals in Indonesia, and (2) to establish the specific priorities of the Indonesian trans* FtM community. In-depth interviews, focus groups, and participant observation was used involving 14 respondents. Findings revealed that respondents experienced othering through rejection, misidentification, harassment, "correction," and bureaucratic discrimination across the five preestablished domains. Health care and a lack of information emerged as areas of particular concern for respondents. This work calls for health care that is sensitive to the needs of trans* FtM people coupled with high-quality information to alleviate the cycles through which discrimination is sustained.

Evolution of cichlid vision via trans-regulatory divergence

2012-12-01

Full Text Available Abstract Background Phenotypic evolution may occur through mutations that affect either the structure or expression of protein-coding genes. Although the evolution of color vision has historically been attributed to structural mutations within the opsin genes, recent research has shown that opsin regulatory mutations can also tune photoreceptor sensitivity and color vision. Visual sensitivity in African cichlid fishes varies as a result of the differential expression of seven opsin genes. We crossed cichlid species that express different opsin gene sets and scanned their genome for expression Quantitative Trait Loci (eQTL responsible for these differences. Our results shed light on the role that different structural, cis-, and trans-regulatory mutations play in the evolution of color vision. Results We identified 11 eQTL that contribute to the divergent expression of five opsin genes. On three linkage groups, several eQTL formed regulatory “hotspots” associated with the expression of multiple opsins. Importantly, however, the majority of the eQTL we identified (8/11 or 73% occur on linkage groups located trans to the opsin genes, suggesting that cichlid color vision has evolved primarily via trans-regulatory divergence. By modeling the impact of just two of these trans-regulatory eQTL, we show that opsin regulatory mutations can alter cichlid photoreceptor sensitivity and color vision at least as much as opsin structural mutations can. Conclusions Combined with previous work, we demonstrate that the evolution of cichlid color vision results from the interplay of structural, cis-, and especially trans-regulatory loci. Although there are numerous examples of structural and cis-regulatory mutations that contribute to phenotypic evolution, our results suggest that trans-regulatory mutations could contribute to phenotypic divergence more commonly than previously expected, especially in systems like color vision, where compensatory changes in the

While the visibility and acceptance of trans women have grown globally in recent years, this progress has primarily been within a traditional, heteronormative narrative. But a growing number of trans women identify as butch lesbians and challenge this heteronormative narrative. The existence of butch trans women has created a debate on where they fit within queer and lesbian communities and how their gender performance fits within traditional butch/femme understandings of lesbian or queer relationships. This article seeks to explore the intersections of gender identity and sexual orientation that butch trans women experience when they engage with lesbian and trans communities.

Objective: To investigate the feasibility and efficacy of trans-jugular catheter-directed thrombolysis (CDT) together with trans-dorsalis pedis vein thrombolysis for the treatment of deep venous thrombosis (DVT) of the lower limbs. Methods: Jugular vein puncture, indwelling catheter and placement of IVC filter were performed in 18 patients with DVT (study group) followed by continuous trans-jugular CDT together with trans-dorsalis pedis vein thrombolysis. During the corresponding period, 16 patients with DVT (control group) received trans-dorsalis pedis vein thrombolysis only. Results: The thrombolytic time and total dose of urokinase in study group and control group were (6.6 ± 2.3) days, (5.52 ± 2.24) x 106 units and (8.2 ± 1.4) days, (7.00 ± 1.66) x 106 units respectively. The thrombolytic time and total dose of urokinase in study group were significantly lower than that in control group (P < 0.05). After the treatment the thigh circumference and calf circumference in study group showed a reduction of (4.6 ± 2.1) cm and (4.0 ± 2.1) cm respectively, which were (3.2 ± 1.7) cm and (2.7 ± 1.5) cm respectively in control group, the difference between two groups was statistically significant (P < 0.05). The complete patent of the veins was 66.7% in study group and 31.3% in control group, the difference between two groups was significant (P < 0.05). In four cases of the study group, the filters were withdrawn through the original puncture site after the thrombus was completely dissolved. Conclusion: Trans-jugular CDT combined with trans-dorsalis pedis vein thrombolysis is an effective and safe therapeutic technique for the treatment of deep venous thrombosis of the lower extremities, moreover, the filter can be taken back via the original puncture site when the thrombus is completely dissolved.

Full Text Available Abstract Background Animal African trypanosomiasis, sleeping sickness in humans and Nagana in cattle, is a resurgent disease in Africa caused by Trypanosoma parasites. Trans-sialidases expressed by trypanosomes play an important role in the infection cycle of insects and mammals. Whereas trans-sialidases of other trypanosomes like the American T. cruzi are well investigated, relatively little research has been done on these enzymes of T. congolense. Results Based on a partial sequence and an open reading frame in the WTSI database, DNA sequences encoding for eleven T. congolense trans-sialidase 1 variants with 96.3% overall amino acid identity were amplified. Trans-sialidase 1 variants were expressed as recombinant proteins, isolated and assayed for trans-sialylation activity. The purified proteins produced α2,3-sialyllactose from lactose by desialylating fetuin, clearly demonstrating their trans-sialidase activity. Using an HPLC-based assay, substrate specificities and kinetic parameters of two variants were characterized in detail indicating differences in substrate specificities for lactose, fetuin and synthetic substrates. Both enzymes were able to sialylate asialofetuin to an extent, which was sufficient to reconstitute binding sites for Siglec-4. A mass spectrometric analysis of the sialylation pattern of glycopeptides from fetuin revealed clear but generally similar changes in the sialylation pattern of the N-glycans on fetuin catalyzed by the trans-sialidases investigated. Conclusions The identification and characterization of a trans-sialidase gene family of the African parasite T. congolense has opened new perspectives for investigating the biological role of these enzymes in Nagana and sleeping sickness. Based on this study it will be interesting to address the expression pattern of these genes and their activities in the different stages of the parasite in its infection cycle. Furthermore, these trans-sialidases have the

Complete text of publication follows. Thiyl radicals radiolytically generated from thiophenol in methanolic solution are known to isomerise double bonds of poly-unsaturated fatty acids (PUFA). γ-irradiating of such a system containing all-cis 5,8,11,14 eicosatetraenoic acid (arachidonic acid, AA) with low doses (0.1-0.8 kGy) results in a mixture of 8 to 32% mono-trans-isomers. Here we report about the influence of mono-trans-AA on the primary steps of AA-metabolism and prostaglandin synthesis, catalysed by cyclooxygenase (COX). In the cell-free model system the reaction of COX-1 with AA was analysed by controlling the oxygen level during the enzymatic reaction. As an example, a mixture of a low quantity of mono-trans-isomerized AA (10%) and 90% all-cis-isomer exhibits a marked reduced oxygen consumption by 45%. As further proofs - the yield of reactive oxygen species (ROS) generated by the COX-coupled peroxidase reaction was detected, - and the COX-1 activity in presence of different amounts of trans-AA was characterized using a photometric assay based on the oxidation of TMPD. All these methods indicated semiquantitatively a reduced activity of COX-1, depending on the trans-isomer yield. Therefore, an inhibition of COX-1 activity by only one trans-double-bond in AA could be concluded. Furthermore, in vitro cell-line experiments were performed analysing the influence of mono-trans-isomerized AA on the activity of the cell-own COX-2. Hence, VD 3 -differentiated and LPS-stimulated monocyte-like cells were incubated with mono-trans-AA and ROS-production was detected by the chemiluminescence measurements mentioned above. Compared to the reaction with all-cis-AA we found a considerable lowered formation of ROS. Likewise, we obtained a reduced PGE 2 -expression between 15 and 40% for cells treated with 8 to 29% trans-AA. The model as well as in vivo experiments demonstrate an inhibition effect of mono-trans-AA and give rise for postulating an enzyme blocking mechanism

One current major hurdle to practical implementation of aerobic granule technology is the frequent occurrence of granule disintegration during long-term operation. However, the mechanism behind this is largely unclear today. Here, 2-decenoic acid, which has been previously demonstrated to be released by Pseudomonas aeruginosa and disperse biofilms, was found to also induce the disintegration of aerobic granules. A comparison of the solution compositions from samples of only trans-2-decenoic acid, only aerobic granules, and granules added with trans-2-decenoic acid shows that bacteria and extracellular polymeric substances (EPS) were stripped from granule surface upon trans-2-decenoic acid dosing. Due to the possible toxicity of trans-2-decenoic acid at a saturation concentration, the disintegrated granules and the milky suspension in the disintegration test showed a significantly lower oxygen uptake rate than the un-integrated granules. This work suggests that trans-2-decenoic acid released by microbes might play a critical role in regulating the disintegration of aerobic granules. Copyright © 2012 Elsevier Ltd.

Cullum, M.E.; Zile, M.H.

1985-01-01

The kinetics and metabolism of physiological doses of all-trans-retinoic acid were examined in blood and small intestinal mucosa of vitamin A-depleted rats. A major portion of intrajugularly injected retinoic acid is rapidly (within 2 min) sequestered by tissues; subsequently 13-cis-retinoic acid and polar metabolites are released into circulation. All-trans-retinoic acid appears in small intestinal epithelium within 2 min after dosing and is the major radioactive compound there for at least 2 h. Retinoyl glucuronide and 13-cis-retinoic acid are early metabolites of all-trans-retinoic acid in the small intestine of bile duct-cannulated rats. Retinoyl glucuronide, the major metabolite of retinoic acid intestinal epithelium, in contrast to other polar metabolites, was not detected in circulation. An examination of [ 3 H]retinyl acetate metabolites under steady state conditions in vitamin A-repleted rats demonstrates the occurrence of all-trans-retinoic acid and 13-cis-retinoic acid in circulation and in intestinal epithelium, in a pattern similar to that found after injection of retinoic acid into vitamin A-depleted rats. These data establish that all-trans-retinoic acid, 13-cis-retinoic acid, and retinoyl glucuronide are physiological metabolites of vitamin A in target tissues, and therefore are important candidates as mediators of the biological effect of the vitamin

Reprogramming the Dynamin 2 mRNA by Spliceosome-mediated RNA Trans-splicing

Directory of Open Access Journals (Sweden)

Delphine Trochet

2016-01-01

Full Text Available Dynamin 2 (DNM2 is a large GTPase, ubiquitously expressed, involved in membrane trafficking and regulation of actin and microtubule cytoskeletons. DNM2 mutations cause autosomal dominant centronuclear myopathy which is a rare congenital myopathy characterized by skeletal muscle weakness and histopathological features including nuclear centralization in absence of regeneration. No curative treatment is currently available for the DNM2-related autosomal dominant centronuclear myopathy. In order to develop therapeutic strategy, we evaluated here the potential of Spliceosome-Mediated RNA Trans-splicing technology to reprogram the Dnm2-mRNA in vitro and in vivo in mice. We show that classical 3′-trans-splicing strategy cannot be considered as accurate therapeutic strategy regarding toxicity of the pre-trans-splicing molecules leading to low rate of trans-splicing in vivo. Thus, we tested alternative strategies devoted to prevent this toxicity and enhance frequency of trans-splicing events. We succeeded to overcome the toxicity through a 5′-trans-splicing strategy which also allows detection of trans-splicing events at mRNA and protein levels in vitro and in vivo. These results suggest that the Spliceosome-Mediated RNA Trans-splicing strategy may be used to reprogram mutated Dnm2-mRNA but highlight the potential toxicity linked to the molecular tools which have to be carefully investigated during preclinical development.

Intact HIV-1 and exosomes can be internalized by dendritic cells (DCs) through a common pathway leading to their transmission to CD4 + T lymphocytes by means of mechanisms defined as trans-infection and trans-dissemination, respectively. We previously reported that exosomes from HIV-1-infected cells activate both uninfected quiescent CD4 + T lymphocytes, which become permissive to HIV-1, and latently infected cells, with release of HIV-1 particles. However, nothing is known about the effects of trans-dissemination of exosomes produced by HIV-1-infected cells on uninfected or latently HIV-1-infected CD4 + T lymphocytes. Here, we report that trans-dissemination of exosomes from HIV-1-infected cells induces cell activation in resting CD4 + T lymphocytes, which appears stronger with mature than immature DCs. Using purified preparations of both HIV-1 and exosomes, we observed that mDC-mediated trans-dissemination of exosomes from HIV-1-infected cells to resting CD4 + T lymphocytes induces efficient trans-infection and HIV-1 expression in target cells. Most relevant, when both mDCs and CD4 + T lymphocytes were isolated from combination anti-retroviral therapy (ART)-treated HIV-1-infected patients, trans-dissemination of exosomes from HIV-1-infected cells led to HIV-1 reactivation from the viral reservoir. In sum, our data suggest a role of exosome trans-dissemination in both HIV-1 spread in the infected host and reactivation of the HIV-1 reservoir.

District heating in Switzerland

International Nuclear Information System (INIS)

Herzog, F.

1991-01-01

District heating has been used in Switzerland for more than 50 years. Its share of the heat market is less than 3% today. An analysis of the use of district heating in various European countries shows that a high share of district heating in the heat market is always dependent on ideal conditions for its use. Market prospects and possible future developments in the use of district heating in Switzerland are described in this paper. The main Swiss producers and distributors of district heating are members of the Association of District Heating Producers and Distributors. This association supports the installation of district heating facilities where ecological, energetical and economic aspects indicate that district heating would be a good solution.

After runaway: The trans-Hill stage of planetesimal growth

International Nuclear Information System (INIS)

Lithwick, Yoram

2014-01-01

When planetesimals begin to grow by coagulation, they first enter an epoch of runaway, during which the biggest bodies grow faster than all the others. The questions of how runaway ends and what comes next have not been answered satisfactorily. We show that runaway is followed by a new stage—the 'trans-Hill stage'—that commences when the bodies that dominate viscous stirring ('big bodies') become trans-Hill, i.e., when their Hill velocity matches the random speed of the small bodies they accrete. Subsequently, the small bodies' random speed grows in lockstep with the big bodies' sizes, such that the system remains in the trans-Hill state. Trans-Hill growth is crucial for determining the efficiency of growing big bodies, as well as their growth timescale and size spectrum. Trans-Hill growth has two sub-stages. In the earlier one, which occurs while the stirring bodies remain sufficiently small, the evolution is collisionless, i.e., collisional cooling among all bodies is irrelevant. The efficiency of forming big bodies in this collisionless sub-stage is very low, ∼10α << 1, where α ∼ 0.005(a/AU) –1 is the ratio between the physical size of a body and its Hill radius. Furthermore, the size spectrum is flat (equal mass per size decade, i.e., q = 4). This collisionless trans-Hill solution explains results from previous coagulation simulations for both the Kuiper Belt and the asteroid belt. The second trans-Hill sub-stage commences once the stirring bodies grow big enough (>α –1 × the size of the accreted small bodies). After that time, collisional cooling among small bodies controls the evolution. The efficiency of forming big bodies rises and the size spectrum becomes more top heavy. Trans-Hill growth can terminate in one of two ways, depending on the sizes of the small bodies. First, mutual accretion of big bodies can become significant and conglomeration proceeds until half of the total mass is converted into big bodies

Murine monoclonal antibodies that bind selectively to adducts formed on DNA by the antitumor drug cis-diamminedichloroplatinum(II), cis-DDP, or to the chemothrapeutically inactive trans isomer trans-DDP were elicited by immunization with calf thymus DNA modified with either cis- or trans-DDP at ratios of bound platinum per nucleotide, (D/N)/sub b/, of 0.06-0.08. The binding of two monoclonal antibodies to cis-DDP-modified DNA was competitively inhibited in an enzyme-linked immunosorbent assay (ELISA) by 4-6 nM concentrations of cis-DDP bound to DNA. Adducts formed by cis-DDP on other synthetic DNA polymers did not inhibit antibody binding to cis-DDP-DNA. The biologically active compounds [Pt(en)Cl 2 ], [Pt(dach)Cl 2 ], and [Pt(NH 3 ) 2 (cbdca)] (carboplatin) all formed antibody-detectable adducts on DNA, whereas the inactive platinum complexes trans-DDP and [Pt(dien)Cl]Cl (dien, diethylenetriamine) did not. The monoclonal antibodies therefore recognize a bifunctional Pt-DNA adduct with cis stereochemistry in which platinum is coordinated by two adjacent guanines or, to a lesser degree, by adjacent adenine and guanine. A monoclonal antibody raised against trans-DDP-DNA was competitively inhibited in an ELISA by 40 nM trans-DDP bound to DNA. This antibody crossreacted with unmodified, denatured DNA. The recognition of cis- or trans-DDP-modified DNAs by monoclonal antibodies thus parallels the known modes of DNA binding of these compounds and may correlate with their biological activities

What are the experiences of trans persons (i.e. those whose gender identity does not match the gender assigned to them at birth) who sought or accessed assisted reproduction (AR) services in Ontario, Canada, between 2007 and 2010? The majority of trans persons report negative experiences with AR service providers. Apart from research examining desire to have children among trans people, most of the literature on this topic has debated the ethics of assisting trans persons to become parents. To-date, all of the published research concerning trans persons' experiences with AR services is solely from the perspective of service providers; no studies have examined the experiences of trans people themselves. Secondary qualitative research study of data from nine trans-identified people and their partners (total n = 11) collected as part of a community-based study of access to AR services for sexual and gender minority people between 2010 and 2012. Trans-identified volunteers (and their partners, when applicable) who had used or attempted to access AR services since 2007 from across Ontario, Canada, participated in a 60-90 minute, semi-structured qualitative interview. Qualitative analysis was performed using a descriptive phenomenological approach. Emerging themes were continually checked against the data as part of an iterative process. The data highlight barriers to accessing AR services for trans people. Participant recommendations for improving AR service provision to better meet the needs of this population are presented. These recommendations address the following areas: (i) AR service provider education and training; (ii) service provider and clinic practices and (iii) clinic environment. The majority of study participants were trans people who identified as men and who resided in major urban areas; those living in smaller communities may have different experiences that were not adequately captured in this analysis. While existing literature debates the ethics of

Standard-setting is a blending of scientific, trans-scientific, and political elements which result in a number of consequences. Health standards, for example, are influenced by biological and philosophical assumptions and scientific traditions, with the dose-response function treated as a trans-scientific question because of scientific uncertainties. Costs and benefits and other values besides health, safety, or environment also enter into the balancing of regulatory decisions and keep regulations from a purely scientific knowledge is desirable. Recommendations that industry be self-regulatory reflect a shift in emphasis from legal enforcement to information-based compliance

TransAlta 2003 annual report

2004-01-01

This annual report presents financial information from TransAlta Corp., along with a review of its operations throughout 2003 and a summary of the how the electric utility has performed in terms of power generation, independent power producers, transmission and energy marketing. TransAlta is one of the largest non-regulated power generation and wholesale marketing companies in Canada. It's assets include coal-fired, gas-fired, hydro and renewable generation facilities in Canada, the United States, Mexico and Australia. Reported earnings in 2003 were $1.26 per share compared to $1.17 in 2002. The strong first quarter was followed by harsh market conditions, low water levels which affected hydro production, and pricing restrictions in Ontario that reduced contribution from the Sarnia plant. This report outlines the utility's progress in increasing revenue and producing more power. In 2003, unplanned outages were reduced by 7 per cent and injury frequency rate was reduced by 27 per cent. The installation of 114 wind turbines in Fort Macleod, Alberta, increased TransAlta's renewable energy capacity to 3.7 per cent in 2003. The wind farm produces 75 MW of electricity, enough to power more than 32,500 homes annually. This report summarized the company's energy resource activities and presented an operations review as well as consolidated financial statements and common share information. This included the utility's assets, liabilities, revenues, expenses and cash flows. Revenue and expenditure statements were summarized by source. refs., tabs., figs

Strange Bedfellows: Anachronisms, Identity Politics, and the Queer Case of Trans.

Science.gov (United States)

Gailey, Nerissa

2017-01-01

This article explores trans identities, as articulated within a few historical texts. From early literary depictions of gender difference, to medicalized conceptions of transsexualism, to a proliferation of trans and queer identities represented by an ever-expanding "alphabet soup" of identity labels, our understandings of identities, sexualities, and queer community-building continue to change. I use the notion of "kind-making," as elaborated on in the work of Ian Hacking, to illustrate that some queer and trans identifications are affiliative, whereas others are contrastive or oppositional in nature, and these structural differences have important implications with respect to understanding identity and sexuality, and also trans inclusion within LGBT communities and activist efforts.

Differential effect of corn oil-based low trans structured fat on the plasma and hepatic lipid profile in an atherogenic mouse model: comparison to hydrogenated trans fat

Full Text Available Abstract Background Trans fat are not desirable in many aspects on health maintenance. Low trans structured fats have been reported to be relatively more safe than trans fats. Methods We examined the effects of low trans structured fat from corn oil (LC, compared with high trans fat shortening, on cholesterol and fatty acid metabolism in apo E deficient mice which is an atherogenic animal model. The animals were fed a high trans fat (10% fat: commercial shortening (CS or a low trans fat (LC diet for 12 weeks. Results LC decreased apo B and hepatic cholesterol and triglyceride concentration compared to the CS group but significantly increased plasma total cholesterol and triglyceride concentration and fecal lipids with a simultaneous increase in HDL-cholesterol level, apo A-I, and the ratio of HDL-cholesterol to total cholesterol (HTR. Reduction of hepatic lipid levels by inclusion of LC intake was observed alongside modulation of hepatic enzyme activities related to cholesterol esterification, fatty acid metabolism and fecal lipids level compared to the CS group. The differential effects of LC intake on the plasma and hepatic lipid profile seemed to be partly due to the fatty acid composition of LC which contains higher MUFA, PUFA and SFA content as well as lower content of trans fatty acids compared to CS. Conclusions We suggest that LC may exert a dual effect on plasma and hepatic lipid metabolism in an atherogenic animal model. Accordingly, LC, supplemented at 10% in diet, had an anti-atherogenic effect on these apo E-/- mice, and increased fecal lipids, decreased hepatic steatosis, but elevated plasma lipids. Further studies are needed to verify the exact mode of action regarding the complex physiological changes and alteration in lipid metabolism caused by LC.

Mechanically induced cis to trans reisomerization of azobenzene

Science.gov (United States)

Turansky, Robert; Konopka, Martin; Stich, Ivan; Marx, Dominik

2007-03-01

Using density functional techniques we study mechanochemistry of the azobenzene molecule. Azobenzene is an optically switchable molecule. Laser light is normally used to achieve molecular switching between the cis and trans isomers. We use mechanochemistry to achieve the switching. Thiolate-gold bond can used to exert mechanical energy on the molecule bonded between two gold electrodes in static AFM apparatus. Our model consists of two realistic gold electrodes bridged by dithioazobenzene. We find that pulling the transisomer leads just to formation of gold nanowires and mechanical breakage of the electrodes. However, mechanochemistry with modest applied forces leads to cis trans reisomerization via rotation mechanism. Contrary, use of simple constraints instead of realistic gold electrodes, leads to cis trans reisomerization, albeit with significantly larger applied forces and via inversion mechanism. Important experimental and theoretical ramifications of these simulations will be discussed.

Endoscopic treatment of trans-sellar trans-sphenoidal encephalocele associated with morning glory syndrome presenting with non-traumatic cerebrospinal fluid rhinorrhea.

Science.gov (United States)

Sasani, M; Ozer, A F; Aydin, A L

2009-03-01

Basal encephaloceles are rare, accounting for about 1.5% of all encephaloceles. The trans-sellar trans-sphenoidal encephalocele variety is the rarest. Morning glory syndrome is often associated with basal encephalocele. Spontaneous cerebrospinal fluid (CSF) rhinorrheas are the least common of these, accounting for only 3% to 5% of all CSF rhinorrheas. The authors describe the outcome of a 10-year follow-up study of a 26-year-old male patient with a spontaneous CSF rhinorrhea occurring trans-sphenoidal encephalocele associated with bilateral morning glory syndrome that was treated with an endoscopic endonasal approach. Endoscopic exploration of the sella floor was performed and closed with abdomen fat packing and muscle fascia. The postoperative course was uneventful. A follow-up magnetic resonance (MR) image at 6 months postoperatively showed extension of encephalocele in the sphenoidal sinus, which was repaired. The patient had no further CSF rhinorrhea and showed no ophthalmologic changes over a follow-up period of over 10 years. Ophthalmologic findings such as strabismus, in association with anomalies of the optic nerve, should alert the physician to the possible presence of an unrecognized skull base midline defect and encephalocele before CSF leakage is seen. The authors believe that a surgeon who has equal confidence in performing the endoscopic endonasal and conventional microscopic trans-sphenoidal approaches should choose the less invasive surgery.

Petrobras-TransPetro developed the TransPetro Emergency Response System in response to emergency situations at large oil pipelines or at terminal facilities located in sea or river harbour areas. The standard of excellence includes full compliance with environmental regulations set by the federal government. A distributed workflow management software called InfoPAE forms the basis of the system in which actions are defined, along with geographic and conventional data. The first prototype of InfoPAE was installed in 1999. Currently it is operational in nearly 80 installations. The basic concepts and functionality of the TransPetro Emergency Response System were outlined in this paper with reference to the mitigative actions that are based on an evaluation of the organization of the emergency teams; the communication procedures; characterization of the installations; definition of accidental scenarios; environmental sensitivity maps; simulation of oil spill trajectories and dispersion behaviour; geographical data of the area surrounding the installations; and, other conventional data related to the installations, including available equipment. The emergency response team can take action as soon as an accident is detected. The action plan involves characterizing several scenarios and delegating mitigative actions to specific sub-teams, each with access to geographic data on the region where the emergency occurred. 13 refs., 3 figs.

Trans-resveratrol (trans-RSV) is a polyphenol with multiples biological properties, such as anti-inflammatory, antioxidant, anti-aging, anti-diabetic, and antiplatelet. It occurs naturally in grapes and derivate, peanuts and berries. Beauvericin (BEA) is a mycotoxin present in cereals that produces cytotoxicity, intracellular reactive oxygen species and lipid peroxidation. The general objective of this research was to evaluate whether trans-RSV could be used as a good polyphenol against damages produced by BEA. Because trans-RSV can be ingested through dietary supplements, to reach this goal, the following specific objectives were proposed: to determine a) the trans-RSV content in different polyphenol dietary supplements by capillary electrophoresis, b) the antioxidant capacity of the trans-RSV in polyphenol supplements, and c) the influence of BEA in the antioxidant capacity of trans-RSV when they are in combination by photochemioluminiscence assay. The results obtained in this study showed that all polyphenol dietary supplements present higher RSV content that the content of the label. The polyphenol supplements present antioxidant capacity. And the combination of trans-RSV and BEA did not affect the antioxidant capacity of trans-RSV. Thus, RSV could contribute to decrease oxidant effects produced by BEA. Copyright © 2017 Elsevier Ltd.

After the discovery that trans fat increases the risk of coronary heart disease, trans fat content of foods have considerably changed. The aim of this study was to systematically review available data on intakes of trans fat and its dietary sources in general populations worldwide. Data from national dietary surveys and population studies published from 1995 onward were searched via Scopus and websites of national public health institutes. Relevant data from 29 countries were identified. The most up to date estimates of total trans fat intake ranged from 0.3 to 4.2 percent of total energy intake (En%) across countries. Seven countries had trans fat intakes higher than the World Health Organization recommendation of 1 En%. In 16 out of 21 countries with data on dietary sources, intakes of trans fat from animal sources were higher than that from industrial sources. Time trend data from 20 countries showed substantial declines in industrial trans fat intake since 1995. In conclusion, nowadays, in the majority of countries for which data are available, average trans fat intake is lower than the recommended maximum intake of 1 En%, with intakes from animal sources being higher than from industrial sources. In the past 20 years, substantial reductions in industrial trans fat have been achieved in many countries. PMID:28783062

O perfil de ácidos graxos foi avaliado através de cromatografia gasosa em coluna capilar de 100m. Os ácidos graxos monoinsaturados trans foram os predominantes entre os isômeros trans. A partir de 10 horas de fritura, o OS formou 2,1% de isômeros mono trans e ao final de 50 horas este valor passou a 14,3% contra uma diminuição do total de ácidos graxos poliinsaturados, que passou de 59,9% antes do processamento para 32,6% após 50h de fritura. Entretanto, a GPHS apresentou 20,2% de ácidos graxos mono trans antes de ser submetida à fritura e após 50 horas apresentou uma concentração de 28%. Houve também, uma diminuição do total de ácidos graxos essenciais séries ômega6 e ômega3, de 12,8% para 7,3% no mesmo período. Os resultados obtidos revelaram que isômeros trans são formados no óleo e na gordura durante o processo de fritura, sendo que a formação de isômeros trans, ocorreu em menor proporção na GPHS, confirmando a sua maior estabilidade em relação ao OS.

Reactions of isotopic exchange of trans-zeatin with high-radioactive tritium water, with gaseous tritium in solution and solid-phase catalytic hydrogenation are studied to prepare trans-zeatin and dihydrozeatin labelled with tritium. It is shown that reaction of isotopic exchange of trans-zeatin with gaseous tritium both in solutions and without solvents at 160 Deg C and above leads to practically total hydrogenation of initial compound with formation of dihydrozeatin labelled with tritium. Isotopic exchange with tritium water permits to prepare zeatin labelled with tritium with 67 % yield and specific radioactivity 0.68 PBq/mol. It is determined that in the case of solid-phase isotopic exchange within 150-155 Deg C temperature interval both dihydrozeatin and trans-zeatin labelled with tritium are formed [ru

Health care for transgender and transsexual (ie, trans) individuals has long been based on a binary understanding of gender (ie, feminine vs masculine). However, the existence of non-binary or genderqueer (NBGQ) genders is increasingly recognized by academic and/or health care professionals. To gain insight into the individual health care experiences and needs of binary and NBGQ individuals to improve their health care outcomes and experience. Data were collected using an online survey study on experiences with trans health care. The non-clinical sample consisted of 415 trans individuals. An individual treatment progress score was calculated to report and compare participants' individual progress toward treatment completion and consider the individual treatment needs and definitions of completed treatment (ie, amount and types of different treatments needed to complete one's medical transition). Main outcome measures were (i) general and trans-related sociodemographic data and (ii) received and planned treatments. Participants reported binary (81.7%) and different NBGQ (18.3%) genders. The 2 groups differed significantly in basic demographic data (eg, mean age; P < .05). NBGQ participants reported significantly fewer received treatments compared with binary participants. For planned treatments, binary participants reported more treatments related to primary sex characteristics only. Binary participants required more treatments for a completed treatment than NBGQ participants (6.0 vs 4.0). There were no differences with regard to individual treatment progress score. Because traditional binary-focused treatment practice could have hindered NBGQ individuals from accessing trans health care or sufficiently articulating their needs, health care professionals are encouraged to provide a holistic and individual treatment approach and acknowledge genders outside the gender binary to address their needs appropriately. Because the study was made inclusive for non

2016-01-01

Private entities engagement in the battle against climate change is a well-established fact, and a source of intense and diversified normative activity. A certain type of climate rules has thus arisen, with a private origin and an international scope, as they transcend the borders of existing territories. In this context, one could wonder about the possible existence of a trans-national climate change law, as a relatively autonomous body of law, which would exist at the margins of international and national climate change law. Building on the discussions that have been conducted about the trans-national law in other areas of regulations, this study intends to provide answers about the possible existence of a trans-national climate change law

2017-12-01

We surveyed 122 trans men using a hybrid sampling method that included randomly selected physical and online venues and peer referral to measure HIV prevalence and risk behaviors. HIV prevalence was 0% (one-sided 97.5% confidence interval 0-3.3%). Of 366 partnerships described, 44.8% were with cisgender women, 23.8% with cisgender men, 20.8% with trans men, and 10.7% with trans women. Condomless receptive anal and front hole/vaginal sex averaged one to three episodes per six months. HIV prevalence in trans men is likely closer to heterosexual cisgender men and women in San Francisco than trans women or MSM. Prevention prioritizing trans women and MSM, coupled with individualized and relevant sexual health education for trans men with partners from these populations, may best address the HIV prevention needs of trans men. Systematic collection of transgender status in Census and health data is needed to understand other health disparities among trans men.

2015-01-15

Objectives: The aim of this study was to compare radiation exposure, assessed by dose-area product (DAP), in right trans-radial approach (RR) versus left trans-radial approach (LR) for coronary procedures. Background: In LR the catheter course is more similar to trans-femoral approach, thus allowing an easier negotiation of coronary ostia which, in turn, might translate into reduced fluoroscopy time (FT) and radiation exposure as compared to RR. Methods: We retrospectively selected diagnostic and interventional procedures (PCI) performed by RR or LR at our center from May 2009 to May 2014. We only included in the analysis the procedures in which DAP values were available. Results: We analyzed 1464 procedures, 1175 of which performed by RR (80.3%) and 289 by LR (19.7%). Median DAP values were significantly higher in RR as compared to LR for diagnostic and interventional procedures (4482 vs. 3540 cGy.cm{sup 2} and 11523 vs. 10086 cGy.cm{sup 2}, respectively; p < 0.05). No significant differences were observed in FT and in contrast volume (CV). In the propensity-matched cohort, consisting of 269 procedures for each group, no significant differences between LR and RR were observed in median DAP values for both diagnostic and interventional procedures (3990 vs. 3542 cGy.cm{sup 2} and 9964 vs. 10216 cGy.cm{sup 2}, respectively; p = ns); FT and CV were also similar. At multiple linear regression analysis laterality of trans-radial approach was not associated with DAP. Conclusions: In an experienced trans-radial center LR is not associated with a reduction in radiation exposure, FT or CV as compared to RR. - Highlights: • Right trans-radial approach is by far more commonly used than left trans-radial approach. • Left trans-radial approach has the advantage of an easier catheter manipulation, more similar to trans-femoral approach. • This could reduce fluoroscopy time and radiation exposure. • We conducted a retrospective study to investigate patient radiation

The canonical molecular machinery required for global mRNA translation and its control has been well defined, with distinct sets of proteins involved in the processes of translation initiation, elongation and termination. Additionally, noncanonical, trans-acting regulatory RNA-binding proteins (RBPs) are necessary to provide mRNA-specific translation, and these interact with 5' and 3' untranslated regions and coding regions of mRNA to regulate ribosome recruitment and transit. Recently it has also been demonstrated that trans-acting ribosomal proteins direct the translation of specific mRNAs. Importantly, it has been shown that subsets of RBPs often work in concert, forming distinct regulatory complexes upon different cellular perturbation, creating an RBP combinatorial code, which through the translation of specific subsets of mRNAs, dictate cell fate. With the development of new methodologies, a plethora of novel RNA binding proteins have recently been identified, although the function of many of these proteins within mRNA translation is unknown. In this review we will discuss these methodologies and their shortcomings when applied to the study of translation, which need to be addressed to enable a better understanding of trans-acting translational regulatory proteins. Moreover, we discuss the protein domains that are responsible for RNA binding as well as the RNA motifs to which they bind, and the role of trans-acting ribosomal proteins in directing the translation of specific mRNAs.

To examine the influence of state laws and district policies on district-wide elementary school and middle school practices related to physical education (PE) time and the percentage of moderate-to-vigorous physical activity (MVPA) time during PE. Multivariate, cross-sectional analysis of state laws, district wellness and PE policies, and district PE practices for school year 2010-2011 controlling for district-level urbanicity, region, size, race/ethnicity of students, and socioeconomic status and clustered on state. One hundred ninety-five public school districts located in 42 states. District-level PE coordinators for the included districts who responded to an online survey. Minutes and days of PE per week and percent time spent in MVPA during PE time. District PE coordinators reported significantly less PE time than national standards-82.9 and 189.6 minutes at the elementary school and middle school levels, respectively. Physical education was provided an average of 2.5 and 3.7 days per week, respectively; and the percentage of MVPA time in PE was 64.4% and 65.7%, respectively. At the elementary school level, districts in either states with laws governing PE time or in a state and district with a law/policy reported significantly more days of PE (0.63 and 0.67 additional days, respectively), and districts in states with PE time laws reported 18 more minutes of PE per week. At the middle school level, state laws were associated with 0.73 more days of PE per week. Neither state laws nor district policies were positively associated with percent MVPA time in PE. State laws and district policies can influence district-level PE practices-particularly those governing the frequency and duration of PE-although opportunities exist to strengthen PE-related laws, policies, and practices.

Full Text Available The objective of this paper is to identify the stakeholders and their contributions to the public consultation carried out with regard to the mandatory trans fat acids food labeling proposal in Brazil. Methodology thematic analysis of the documents. Results 25 stakeholders made suggestions regarding the proposed law, and the majority belonged to the food industry sector. The following issues were raised: lack of knowledge among the consumers about trans fat acids; lack of information about trans fat acids in food composition tables and infrastructure to analyse the trans fat content of foods; voluntary trans fat labelling. Conclusions The stakeholders addressed important issues, such as improving nutritional knowledge among the population. However, few stakeholders linked to consumers took part in the public consultation, which might lead to disproportionate influence of the food industry on the development of future food policies.

Financial information from TransCanada was presented along with a review of their operations throughout 2000, including a summary of actions in the area of management, strategy, and policy. The company's efforts in 2000 were directed at restoring and strengthening their financial position by strengthening their balance sheet, restoring earnings, establishing a growth platform for future earnings and positioning the company with discretionary cash flow. In 2000, TransCanada substantially completed its divestiture program and sold assets for proceeds of nearly $3.4 billion. These proceeds have been used mainly to reduce debt and associated financial charges. TransCanada also made successful bids in Alberta's power auctions, increased ownership in Ocean State power and TransCanada Power, L.P. In addition, the company began development of two new power plants in Alberta. These initiatives are expected to contribute to an increase in earnings. tabs., figs

Few atom chemistry of the trans actinide element rutherfordium (Rf)

Nagame, Y.

2002-01-01

Studies of chemical properties of the trans actinide elements - starting with element 104 (Rf) - offer the unique opportunity to obtain information about trends in the Periodic Table at the limits of nuclear stability and to assess the magnitude of the influence of relativistic effects on chemical properties. To explore experimentally the influence of relativistic effects of electron shell structure, we study the chemical properties of the trans actinide elements. So far, we have developed some experimental apparatuses for the study of chemical properties of the trans actinide elements: a beam-line safety system for the usage of the gas-jet coupled radioactive 248 Cm target chamber for the production of trans actinides, a rotating wheel catcher apparatus for the measurement of α particles and spontaneous fission decay of trans actinides and an automated rapid chemical separation apparatus based on high performance liquid chromatography. The trans actinide nuclide, the element 104, 261 Rf (t 1/2 = 78 s) has been successfully produced via the reactions of 248 Cm( 18 O,5n) at the JAERI (Japan Atomic Energy Research Institute) tandem accelerator. The evaluated production cross section was about 10 nb, indicating that the production rate was approximately 2 atoms per min. Because of the short half-life and the low production rate of Rf, each atom produced decays before a new atom is synthesized. It means that any chemistry to be performed must be done on an 'atom-at-a-time' basis. Therefore rapid, very efficient and selective chemical procedures are indispensable to isolate the desired trans actinide 261 Rf. To perform fast and repetitive ion-exchange separation of Rf, we have developed the apparatus AIDA (Automated Ion exchange separation system coupled with the Detection apparatus for Alpha spectroscopy). Recently, ion-exchange behavior of Rf in acidic solutions has been studied with AIDA, and the results indicate that anion-exchange behavior of Rf is quite similar

Sebedio Jean-Louis

2000-01-01

Full Text Available Les acides gras trans polyinsaturés sont formés à partir des acides gras indispensables (acides linoléique et a-linolénique au cours des traitements technologiques comme par exemple le raffinage des huiles ou la friture [1, 2]. L’acide linolénique est plus sensible à l’isomérisation que l’acide linoléique. En effet, comme l’a montré Wolff dans une revue récente [3], le degré d’isomérisation de l’acide linolénique peut atteindre 30 à 35 %. On retrouve également ces pourcentages dans les formules infantiles et le lait de femme [1]. Les principaux isomères formés sont les composés monotrans, à savoir les 18 :2-9trans,12cis, 18 :2-9cis,12trans, 18 :3-9trans,12cis,15cis, et le 18 :3-9cis,12cis,15-trans. Cependant, une température de désodorisation supérieure à 220 °C entraîne la formation d’isomères di-trans [4]. À titre d’exemple, nous avons représenté dans le tableau le contenu de quelques huiles végétales en isomères des acides linoléique et a-linolénique. Compte tenu de leur présence dans l’alimentation, on peut s’interroger sur les conséquences nutritionnelles et biochimiques de leur ingestion.

Full Text Available Trans Sarbagita merupakan salah satu upaya pemerintah Bali dalam menyediakan fasilitas angkutan umum untuk mengurangi kemacetan. Trans Sarbagita adalah sebuah fasilitas BRT (Bus Rapid Transit yang memiliki angkutan pengumpan tersendiri untuk mengangkut penumpang ke halte-halte bus terdekat. Trans Sarbagita sendiri sudah memiliki rencana rute untuk armada bus dan pengumpan mereka. Dari sebagian rute yang sudah beroperasi, informasi seputar rute, dan halte yang sudah beroperasi dirasa belum terpublikasi dengan baik sehingga dapat menjadi masalah bukan hanya untuk masyarakat Bali, tapi juga untuk para wisatawan yang ingin menggunakan fasilitas tersebut. Salah satu cara mengatasi permasalahan tersebut adalah dengan membangun sebuah aplikasi yang berisikan informasi mengenai halte dan rute-rute yang dapat ditempuh untuk mencapai tujuan yang dapat diakses melalui perangkat bergerak. Aplikasi Trans Sarbagita dapat memberikan rute terpendek yang dapat dilalui trayek pengumpan berdasarkan lokasi awal dan tujuan pengguna yang dikalkulasikan dengan algoritma Dijkstra. Selain menampilkan rute terpendek, aplikasi ini juga dapat menampilkan rute trayek serta lokasi halte Trans Sarbagita yang sudah beroperasi. Hasil uji coba sistem sudah menunjukkan berjalannya sistem dengan baik sesuai dengan perancangan awal. Meskipun demikian pengembangan lebih lanjut masih dibutuhkan untuk mengimbangi berkembangnya teknologi, serta berubahnya kebutuhan pengguna yang dapat diaplikasikan pada aplikasi ini.

News media coverage of trans fat: health risks and policy responses.

Science.gov (United States)

Jarlenski, Marian; Barry, Colleen L

2013-01-01

Prior research indicates that the news media play a critical role in transmitting information to the public about the most pressing public health problems, and framing attributions about who in society is responsible for solving these problems. In this article, we use content analysis methods to study the agenda-setting and framing functions of the news media in shaping perceptions about the health risks posed by trans fat in the U.S. diet. A census of news stories focusing on trans fat was collected from the two largest circulation U.S. newspapers and three major television networks from 1998 to 2008 (N = 156). The content of news coverage was analyzed using a 23-item instrument. Findings indicated that the news media served an important agenda-setting role in educating the public about the presence of trans fat in the U.S. diet and describing the health risks these foods pose. In addition, results indicate that news media coverage framed attributions of responsibility for solving the problem of trans fat in the food supply. News stories noting the heart disease risks of trans fat were significantly more likely to mention governmental responses aimed at curbing consumption than news coverage that did not note these health risks.

Nakajima, Hiroshi; Yamamoto, Sumiko; Katsuhira, Junji

2018-07-01

Patients with diabetes often develop diabetic peripheral neuropathy, which is a distal symmetric polyneuropathy, so foot function on the non-amputated side is expected to affect gait in vascular trans-tibial amputees. However, there is little information on the kinematics and kinetics of gait or the effects of diabetic peripheral neuropathy in vascular trans-tibial amputees. This study aimed to clarify these effects, including the biomechanics of the ankle on the non-amputated side. Participants were 10 vascular trans-tibial amputees with diabetic peripheral neuropathy (group V) and 8 traumatic trans-tibial amputees (group T). Each subject's gait was analyzed at a self-selected speed using a three-dimensional motion analyzer and force plates. Ankle plantarflexion angle, heel elevation angle, and peak and impulse of anterior ground reaction force were smaller on the non-amputated side during pre-swing in group V than in group T. Center of gravity during pre-swing on the non-amputated side was lower in group V than in group T. Hip extension torque during loading response on the prosthetic side was greater in group V than in group T. These findings suggest that the biomechanical function of the ankle on the non-amputated side during pre-swing is poorer in vascular trans-tibial amputees with DPN than in traumatic trans-tibial amputees; the height of the center of gravity could not be maintained during this phase in vascular trans-tibial amputees with diabetic peripheral neuropathy. The hip joint on the prosthetic side compensated for this diminished function at the ankle during loading response. Copyright © 2018 Elsevier Ltd. All rights reserved.

Moulin Julie

2007-04-01

Full Text Available Abstract Consumption of trans fats is associated with an increase of cardiovascular disease (CVD risk. To comply with regulatory policies and public health authorities recommendations, trans fats should be replaced in food products. The study by Sundram et al. (Nutrition & Metabolism 2007, 4:3 reporting the effect on CVD risk factors of interesterified fat (IE and partially hydrogenated soybean oil (PHSO compared to palm olein (POL has been critically analyzed. The study design and in particular the composition of the tested fats was not suitable to properly answer the question raised regarding the effect of alternative ingredients to trans fats on plasma lipids. The observed effects are divergent with predicted data derived from the literature model consolidated using the individual results of 60 randomized clinical trials. The results of the study published by Sundram and co-workers have to be considered with awareness.

Full Text Available Se estudió la biotransformación de ácido trans-cinámico mediante células completas del hongo fitopatógeno nativo colombiano Colletotrichum acutatum. Inicialmente, se evaluó la fungitoxicidad de este compuesto contraC. acutatum; el ácido trans-cinámico exhibió una toxicidad moderada a débil contra el microorganismo y aparentemente se presentó un mecanismo de detoxificación. Luego, para estudiar tal mecanismo y explorar la capacidad de este hongo para biotransformar el ácido trans-cinámico en productos con valor agregado, el microorganismo se incubó con el sustrato usando tres medios de cultivo diferentes (Czapeck-Dox, Sabouraud y PDB a condiciones ambientales. Usando el medio Czapeck-Dox, los cultivos completos de C.acutatum redujeron el ácido trans-cinámico, primero a aldehídos (transcinamaldehido y 3-fenilpropanal, luego a alcoholes (alcohol cinamílico y 3-fenil-1-propanol. Posteriormente, estos alcoholes fueron transformados a los correspondientes ésteres de acetilo. Sin embargo, algunos de estos productos estuvieron ausentes o presentes a una concentración diferente cuando se cambió el medio de cultivo. Los resultados sugieren un mecanismo de detoxificación en el cual el sistema carbonílico α,β-insaturado es afectado.Por otra parte, los productos metabólicos formados son compuestos útiles usados como fragancias y sabores. Por consiguiente, el metabolismo del ácido trans-cinámico usando C. acutatum puede proporcionar nuevos blancos metabólicos para controlar C. acutatum así como también una forma simple y eficiente para obtener sabores y perfumes, tales como el alcohol cinamílico y el 3-fenil-1-propanol, y sus ésteres de acetilo.

Relic dark energy from the trans-Planckian regime

International Nuclear Information System (INIS)

Mersini, Laura; Bastero-Gil, Mar; Kanti, Panagiota

2001-01-01

As yet, there is no underlying fundamental theory for the trans-Planckian regime. There is a need to address the issue of how the observables in our present Universe are affected by processes that may have occurred at super-Planckian energies (referred to as the trans-Planckian regime). Specifically, we focus on the impact the trans-Planckian regime has on two observables: namely, dark energy and the cosmic microwave background radiation (CMBR) spectrum. We model the trans-Planckian regime by introducing a 1-parameter family of smooth non-linear dispersion relations which modify the frequencies at very short distances. A particular feature of the family of dispersion functions chosen is the production of ultralow frequencies at very high momenta k (for k>M P ). We name the range of the ultralow energy modes (of very short distances) that have frequencies equal to or less than the current Hubble rate H 0 as the tail modes. These modes are still frozen today due to the expansion of the Universe. We calculate their energy today and show that the tail provides a strong candidate for the dark energy of the Universe. During inflation, their energy is about 122 to 123 orders of magnitude smaller than the total energy, for any random value of the free parameter in the family of dispersion relations. For this family of dispersions, we present the exact solutions and show that the CMBR spectrum is that of a (nearly) blackbody, and that the adiabatic vacuum is the only choice for the initial conditions

1999-12-01

Full Text Available Olive oil (blend of refined and virgin and sunflower oil containing added methanol phenolic extracts of dry rosemary and olive vegetable water or the synthetic antioxidant BHA in combination with the extracts, were used in a frying process. Eight frying operations were performed at 180 °C with 24 hr intervals between fryings. During the frying period the trans fatty acids (TFA by capillary column gas chromatography (CC-GC were determined. Trans fatty acids of oleic and linoleic were increased with frying time in both the control oil samples. The rosemary additives (extracts alone and in combination with BHA decreased the level of trans fatty acids (mainly elaidic acid, while the addition of olive vegetable water did not have any effect.

To explore the feasibility and value of trans-fissure approaches in brain surgery through individually designed craniotomy. Ninety patients with intracranial space-occupying lesions, 47 males and 58 females, aged (43 +/- 14) (1 - 68), were treated by individualized trans-fissure approach surgeries. Linear scalp incision or "horseshoe shape" scalp incision were designed to perform the operation, with a bone flap 3 - 4 cm in diameter. The shortest approach to reach the lesion was decided under the guidance of neuro-navigation and real-time B-mode ultrasonography. Then the lesions were removed through natural cortical fissures. Another 79 patients with intracranial space-occupying lesions, 53 males and 51 females, aged (42 +/- 11) (15 -73), undergoing classical surgeries in the same period were used as control group. The average operation time, size of bone flap, amount of blood loss, hospitalization time, and hospitalization cost were compared between these 2 groups. The operation time of the individually designed trans-fissure approach group was (3.1 +/- 1.6) hours (1.33 - 10.83 hours), significantly shorter than that of the control group [(4.8 +/- 1.9) hrs, P trans-fissure approach group was (173 +/- 168) ml (20 m - 500 ml), significantly less than that of the control group [(410 +/- 61) ml, P trans-fissure approach group was (12 +/- 5) cm2 [(1 - 25) cm2], significantly smaller than that of the control group [(20. +/- 9) cm2, P trans-fissure approach group received retransfusion, compared to 15 in the control group, during operation. No infection or other significant complications occurred after operation in the individually designed trans-fissure approach group. The hospitalization time of the individually designed trans-fissure approach group was (20 +/- 6) days (9 - 39 days), significantly shorter than that of the control group [(24 +/- 7) days, P trans-fissure approach group was (23171 +/- 7280) yuan RMB; significantly lower than that of the control group

Downs, Shauna M; Singh, Archna; Gupta, Vidhu; Lock, Karen; Ghosh-Jerath, Suparna

2015-07-22

The World Health Organization (WHO) recommends virtually eliminating trans fat from the global food supply. Although several high-income countries have successfully reduced trans fat levels in foods, low- and middle-income countries such as India face additional challenges to its removal from the food supply. This study provides a systems analysis of the Indian food chain to assess intervention options for reducing trans fat intake in low-income consumers. Data were collected at the manufacturer, retailer and consumer levels. Qualitative interviews were conducted with vanaspati manufacturers (n = 13) and local food vendors (n = 44). Laboratory analyses (n = 39) of street foods/snacks sold by the vendors were also conducted. Trans fat and snack intakes were also examined in low-income consumers in two rural villages (n = 260) and an urban slum (n = 261). Manufacturers of vanaspati described reducing trans fat levels as feasible but identified challenges in using healthier oils. The fat content of sampled oils from street vendors contained high levels of saturated fat (24.7-69.3 % of total fat) and trans fat (0.1-29.9 % of total fat). Households were consuming snacks high in trans fat as part of daily diets (31 % village and 84.3 % of slum households) and 4 % of rural and 13 % of urban households exceeded WHO recommendations for trans fat intakes. A multisectoral food chain approach to reducing trans fat is needed in India and likely in other low- and middle-income countries worldwide. This will require investment in development of competitively priced bakery shortenings and economic incentives for manufacturing foods using healthier oils. Increased production of healthier oils will also be required alongside these investments, which will become increasingly important as more and more countries begin investing in palm oil production.

2018-04-01

TransCon growth hormone (GH) is a sustained-release inactive prodrug consisting of unmodified GH transiently bound to an inert carrier molecule designed to release fully active GH over a one-week period. This was a first-in-man phase 1 randomized trial was to evaluate the safety, tolerability, immunogenicity, pharmacokinetics (PK), and pharmacodynamics (PD) of a single dose of TransCon GH as compared to equivalent doses of daily GH (Omnitrope) or placebo in healthy adults. Forty-four healthy male adults were randomized to 4 cohorts of 11 subjects, distributed in a 7:2:2 ratio (TransCon GH: Omnitrope: placebo). A single injection of 4 possible TransCon GH doses (i.e., 0.04, 0.08, 0.16, or 0.24mg GH/kg/wk) or two different Omnitrope doses (i.e., 0.08 or 0.16mg GH/kg/wk divided into 7 equal daily doses) were administered with subjects evaluated for adverse events, immunogenicity, and GH and insulin-like growth factor-1 (IGF-1) levels. TransCon GH was well tolerated; no serious adverse events occurred, no injection site reaction differences between TransCon GH, Omnitrope, or placebo were identified, no nodules or lipoatrophy were reported, and no anti-GH binding antibodies or ECG changes were detected. Overall, the exposure of GH (C max ) and IGF-1 (AUC 0-168h ) following administration of equivalent doses of TransCon GH and Omnitrope were similar. GH and IGF-1 kinetics showed a dose-proportional increase following a single SC administration of TransCon GH and indicated that the prodrug is suitable for weekly administration. These results support advancement of TransCon GH to pediatric and adult GHD trials. Clinical trial registration numbers: NCT01010425 (clinicaltrials.gov). Copyright © 2017 Elsevier Ltd.

Carabez, Rebecca; Pellegrini, Marion; Mankovitz, Andrea; Eliason, Mickey; Scott, Megan

2015-11-01

To describe nurses confusion around trans* terminology and to provide a lesson in Trans* 101 for readers. Of the estimated 9 million persons in the United States of America who are identified as lesbian, gay, bisexual and transgender, about 950,000 (0.2-0.5% of adult population) are identified as trans* (a term that encompasses the spectrum, including transgender, transsexual, trans man, trans woman and other terms). The Institute of Medicine (2011, The health of lesbian, gay, bisexual and transgender people: Building a foundation for better understanding. The National Academies Press, Washington, DC) identified transgender persons as an understudied population with significant need for health research, yet the nursing literature contains little guidance for educating nurses on trans* issues. This is a mixed methods structured interview design with nurse key informants. The scripted interview was based on the Health Care Equality Index, which evaluates patient-centred care to lesbian, gay, bisexual and transgender patients and families. These data were part of a larger research study that explored the current state of lesbian, gay, bisexual and transgender-sensitive nursing practice. Undergraduate nursing students recruited and interviewed 268 nurse key informants about gender inclusive forms (capable of identifying trans* patients) at their agencies. Only 5% reported use of gender inclusive forms, 44% did not know about inclusive forms, 37% did not understand what a gender inclusive form was and 14% confused gender with sexual orientation. The study demonstrated a critical need for education in gender identity and sexual orientation terminology. The lack of understanding of concepts and terminology may affect basic care of lesbian, gay, bisexual and transgender patients especially those who identify as transgender. © 2015 John Wiley & Sons Ltd.

Standing balance in people with trans-tibial amputation due to vascular causes: A literature review.

Science.gov (United States)

Seth, Mayank; Lamberg, Eric

2017-08-01

Balance is an important variable to consider during the rehabilitation process of individuals with trans-tibial amputation. Limited evidence exists on the balance abilities of people with trans-tibial amputation due to vascular causes. The purpose of this article is to review literature and determine if standing balance is diminished in people with trans-tibial amputation due to vascular causes. Literature review. Data were obtained from PubMed, Google Scholar, OandP.org , CINHAL, and Science Direct. Studies were selected only if they included standing balance assessment of people with unilateral trans-tibial amputation due to vascular causes. The review yielded seven articles that met the inclusion criteria. The general test methodology required participants to stand still on force platforms, with feet together, while center of pressure or postural sway was recorded. According to the findings of this review, individuals with trans-tibial amputees due to vascular causes have diminished balance abilities. Limited evidence suggests their balance might be further diminished as compared to individuals with trans-tibial amputation due to trauma. Although the evidence is limited, because of the underlying pathology and presence of comorbidities in individuals with trans-tibial amputation due to vascular causes, one cannot ignore these findings, as even a minor injury from a fall may develop into a non-healing ulcer and affect their health and well-being more severely than individuals with trans-tibial amputation due to trauma.

There is a paucity of systematic research in the area of non-suicidal self-injury (NSSI) in trans people. The aim of this study was to investigate the prevalence of NSSI in trans people and the associations with intra- and interpersonal problems. Participants were 155 untreated individuals with a diagnosis of transsexualism (according to International Classification of Disease-10 criteria) attending a national gender identity clinic. All participants completed the Self-Injury Questionnaire, the Symptom Checklist-90-Revised, the Rosenberg Self-Esteem Scale, the Hamburg Body Drawing Scale, the Experiences of Transphobia Scale, the Inventory of Interpersonal Problems-32, and the Multidimensional Scale of Perceived Social Support. The sample consisted of 66.5% trans women and 33.5% trans men and 36.8% of them had a history of engaging in NSSI. The prevalence of NSSI was significantly higher in trans men (57.7%) compared with trans women (26.2%). Trans individuals with NSSI reported more psychological and interpersonal problems and perceived less social support compared with trans individuals without NSSI. Moreover, the probability of having experienced physical harassment related to being trans was highest in trans women with NSSI (compared with those without NSSI). The study found that with respect to psychological symptoms, trans women reported significantly more intrapersonal and interpersonal symptoms compared with trans men. Finally, the results of the regression analysis showed that the probability of engaging in NSSI by trans individuals was significantly positively related to a younger age, being trans male, and reporting more psychological symptoms. The high levels of NSSI behavior and its association with interpersonal and interpersonal difficulties and lack of social support need to be taken into consideration when assessing trans individuals. The effect of cross-sex hormones and sex reassignment surgery on psychological functioning, including NSSI behavior

FACTS ABOUT TRANS FATTY ACIDS

Full Text Available Introduction Fatty acids constitute the main class of lipids in the human diet, being found in nature mainly as glycerol esters that originate triacylglycerols. In the vegetal and animal kingdoms, fatty acids generally have cis unsaturations. In this form, the hydrogens bound to the double bond carbons are on the same side. In another possible configuration, called trans, the hydrogens are bound to un saturations, carbons on opposing sides. Fatty acids with one or more un saturations in the trans configuration are called trans fatty acids (TFAs.1-4      There are two major sources of TFA, those that come from ruminant animals and those that are industrially produced.      The majority of TFAs are found in partially hydrogenated vegetable oils, which contain 10–40% as TFA.5 Hydrogenation is based on the reaction of unsaturated fatty acids of either vegetable or marine oil in the presence of a catalyst, in general nickel. The objective is to increase the oxidative stability of oils by reduction of the concentration of more unsaturated fatty acids and changing their physical properties, thus extending their application. Hydrogenation depends mainly on oil temperature, hydrogen pressure, stirring speed, reaction time, and the catalyst type and concentration. According to the process conditions, hydrogenation is classified as either partial or total and either selective or nonselective.6 It has been estimated that dietary TFAs from partially hydrogenated oils may be responsible for between 30,000 and 100,000 premature coronary deaths per year in the United States.7      The concentration of TFA in meat and milk from ruminants (i.e., cattle, sheep, goats, etc. contain 3 to 8% of total fat.5 It is hypothesized that ruminant TFAs, or certain TFA isomers from ruminant sources, may confer some health benefits; however, since TFA from animal sources accompany saturated fatty acids (SFA, an increase in a single ruminant TFA in the diet is not

This paper describes the synthesis, spectroscopic characterization and quantum mechanical calculations of three azo-azomethine dyes. The dyes were synthesized via condensation reaction between 4-(dimethylamino)benzaldehyde and three different 4-aminobenzene azo dyes. Quantum chemical calculations on the optimized molecular geometry and electron densities of the trans (E) and cis (Z) isomers and their vibrational frequencies have been computed by using DFT/B3LYP density-functional theory with 6-311++G(d,p) basis set in vacuo. The thermodynamic parameters such as total electronic energy E (RB3LYP), enthalpy H 298 (sum of electronic and thermal enthalpies), free Gibbs energy G 298 (sum of electronic and thermal free Gibbs energies) and dipole moment μ were computed for trans (E) and cis (Z) isomers in order to estimate the ΔE trans→cis , Δμ trans→cis, ΔH trans→cis , ΔG trans→cis and ΔS trans→cis values. After molecular geometry optimization the electronic spectra have been obtained by TD-DFT calculations at same basis set and correlated with the spectra of vapour deposited nanosized films of the dyes. The NBO analysis was performed in order to understand the intramolecular charge transfer and energy of resonance stabilization. Solvatochromism was investigated by UV-VIS spectroscopy in five different organic solvents with increasing polarity. The dynamic photoisomerization experiments have been performed in DMF by pump lasers λ=355nm (mostly E→Z) and λ=491nm (mostly Z→E) in spectral region 300nm - 800nm at equal concentrations and times of illumination in order to investigate the photodynamical trans-cis-trans properties of the CHN and NN chromophore groups of the dyes.

Energetics and Kinetics of trans-SNARE Zippering

Science.gov (United States)

Rebane, Aleksander A.; Shu, Tong; Krishnakumar, Shyam; Rothman, James E.; Zhang, Yongli

Synaptic exocytosis relies on assembly of soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins into a four-helix bundle to drive membrane fusion. Complementary SNAREs anchored to the synaptic vesicle (v-SNARE) and the plasma membrane (t-SNARE) associate from their N-termini, transiting a half-assembled intermediate (trans-SNARE), and ending at their C-termini with a rapid power stroke that leads to membrane fusion. Although cytosolic SNARE assembly has been characterized, it remains unknown how membranes modulate the energetics and kinetics of SNARE assembly. Here, we present optical tweezers measurements on folding of single membrane proteins in phospholipid bilayers. To our knowledge, this is the first such report. We measured the energetics, kinetics, and assembly intermediates of trans-SNAREs formed between a t-SNARE inserted into a bead-supported bilayer and a v-SNARE in a nanodisc. We found that the repulsive force of the apposed membranes increases the lifetime of the half-assembled intermediate. Our findings provide a single-molecule platform to study the regulation of trans-SNARE assembly by proteins that act on the half-assembled state, and thus reveal the mechanistic basis of the speed and high fidelity of synaptic transmission.

The trigemino-cardiac reflex has been reported to occur during various craniofacial surgeries or procedures including manipulation of the trigeminal ganglion, tumor resection in the cerebellopontine angle, various facial reconstructions and trans-sphenoidal adenomectomy. Regarding risk factors during trans-sphenoidal adenomectomy, invasiveness closely related to the size of tumor and the degree of manipulation of cavernous sinus wall have been reported. We report the case of a 40-year-old female patient who had a relatively small-sized (trans-sphenoidal operation of the wall of the cavernous sinus, which strongly suggests the importance of careful manipulation of the cavernous sinus wall. In addition to reporting this rare complication of trans-sphenoidal adenomectomy, we reviewed its clinical management by performing a literature search.

Future Services for District Heating Solutions in Residential Districts

2014-06-01

Full Text Available The underlying assumption of this study is that in order to retain the competitiveness while reaching for the EU targets regarding low-energy construction, district heating companies need to develop new business and service models. How district heating companies could broaden their perspective and switch to a more service-oriented way of thinking is a key interest of our research. The used methods in our study are house builder interviews and a questionnaire. With the help of these methods we discussed the potential interest in heating related services acquiring a comprehensive understanding of the customer needs. The results indicate the importance of certain criteria when choosing the heating system in households: easiness, comfort and affordability seem to dominate the house builders’ preferences. Also environmental awareness seems to be for many an important factor when making a decision about the heating of the house. Altogether, based on the results of this study, we suggest that the prospects of district heating could benefit from highlighting certain aspects and strengths in the future. District heating companies need to increase flexibility, readiness to adopt new services, to invest in new marketing strategies and improving the communication skills.

The Goldwater Rule has been debated, redefined, and debated further since the election of Donald Trump as President of the United States. This column offers a perspective on the Goldwater Rule that moves beyond psychiatry's current preoccupation with precision DSM-5 diagnosis of individuals, which ethically requires consent or other legal authorization for release of diagnostic information to others, and into the realm of leadership as seen through the "trans-dyadic" lens of psychoanalytic understanding of large group processes on a societal level. Concepts from large group psychology are introduced to illustrate "trans-dyadic" perspectives on leadership that do not challenge the Goldwater Rule.

Synthesis of racemic [methyl-d3]-labeled cis- and trans-3'-hydroxycotinine

International Nuclear Information System (INIS)

Ravard, A.; Crooks, P.A.

1994-01-01

A method is described for the synthesis of the racemic [methyl-d 3 ] forms of the nicotine metabolites cis-3'-hydroxycotinine and trans-3'-hydroxycotinine. The key intermediate was [methyl-d 3 ]-N-methylhydroxylamine, obtained from a selective hydrogenation of d 3 -nitro-methane. This intermediate was converted to [methyl-d 3 ]-α-3-pyridyl-N-methylnitrone, which was condensed with methyl acrylate to give a mixture of isomeric isoxazolidines. The hydrogenolysis of this mixture afforded a 70:30 mixture of [methyl-d 3 ] cis- and trans-3'-hydroxycotinine, from which the pure cis-isomer could be isolated by recrystallization from acetone. [Methyl-d 3 ]-trans-3'-hydroxycotinine could be prepared in high yield from the cis-isomer via chiral inversion utilizing a Mitsunobu reaction, or by chromatographic separation from a mixture of the cis- and trans-3'-benzoyloxycotinine, followed by O-debenzoylation in methanolic NaOH.

Xiang, Enming; Guo, Rongwen; Dosso, Stan E.; Liu, Jianxin; Dong, Hao; Ren, Zhengyong

2018-06-01

This paper develops an efficient hierarchical trans-dimensional (trans-D) Bayesian algorithm to invert magnetotelluric (MT) data for subsurface geoelectrical structure, with unknown geophysical model parameterization (the number of conductivity-layer interfaces) and data-error models parameterized by an auto-regressive (AR) process to account for potential error correlations. The reversible-jump Markov-chain Monte Carlo algorithm, which adds/removes interfaces and AR parameters in birth/death steps, is applied to sample the trans-D posterior probability density for model parameterization, model parameters, error variance and AR parameters, accounting for the uncertainties of model dimension and data-error statistics in the uncertainty estimates of the conductivity profile. To provide efficient sampling over the multiple subspaces of different dimensions, advanced proposal schemes are applied. Parameter perturbations are carried out in principal-component space, defined by eigen-decomposition of the unit-lag model covariance matrix, to minimize the effect of inter-parameter correlations and provide effective perturbation directions and length scales. Parameters of new layers in birth steps are proposed from the prior, instead of focused distributions centred at existing values, to improve birth acceptance rates. Parallel tempering, based on a series of parallel interacting Markov chains with successively relaxed likelihoods, is applied to improve chain mixing over model dimensions. The trans-D inversion is applied in a simulation study to examine the resolution of model structure according to the data information content. The inversion is also applied to a measured MT data set from south-central Australia.

ABSTRACT HIV-1-infected nonprogressors (NP) inhibit disease progression for years without antiretroviral therapy. Defining the mechanisms for this resistance to disease progression could be important in determining strategies for controlling HIV-1 infection. Here we show that two types of professional antigen-presenting cells (APC), i.e., dendritic cells (DC) and B lymphocytes, from NP lacked the ability to mediate HIV-1 trans infection of CD4(+) T cells. In contrast, APC from HIV-1-infected progressors (PR) and HIV-1-seronegative donors (SN) were highly effective in mediating HIV-1 trans infection. Direct cis infection of T cells with HIV-1 was comparably efficient among NP, PR, and SN. Lack of HIV-1 trans infection in NP was linked to lower cholesterol levels and an increase in the levels of the reverse cholesterol transporter ABCA1 (ATP-binding cassette transporter A1) in APC but not in T cells. Moreover, trans infection mediated by APC from NP could be restored by reconstitution of cholesterol and by inhibiting ABCA1 by mRNA interference. Importantly, this appears to be an inherited trait, as it was evident in APC obtained from NP prior to their primary HIV-1 infection. The present study demonstrates a new mechanism wherein enhanced lipid metabolism in APC results in remarkable control of HIV-1 trans infection that directly relates to lack of HIV-1 disease progression. IMPORTANCE HIV-1 can be captured by antigen-presenting cells (APC) such as dendritic cells and transferred to CD4 helper T cells, which results in greatly enhanced viral replication by a mechanism termed trans infection. A small percentage of HIV-1-infected persons are able to control disease progression for many years without antiretroviral therapy. In our study, we linked this lack of disease progression to a profound inability of APC from these individuals to trans infect T cells. This effect was due to altered lipid metabolism in their APC, which appears to be an inherited trait. These

Trans Fat Bans and Human Freedom

Science.gov (United States)

Resnik, David

2014-01-01

A growing body of evidence has linked consumption of trans fatty acids to cardiovascular disease. To promote public health, numerous state and local governments in the United States have banned the use of artificial trans fats in restaurant foods, and additional bans may follow. Although these policies may have a positive impact on human health, they open the door to excessive government control over food, which could restrict dietary choices, interfere with cultural, ethnic, and religious traditions, and exacerbate socioeconomic inequalities. These slippery slope concerns cannot be dismissed as far-fetched, because the social and political pressures are place to induce additional food regulations. To protect human freedom and other values, policies that significantly restrict food choices, such as bans on types of food, should be adopted only when they are supported by substantial scientific evidence, and when policies that impose fewer restrictions on freedom, such as educational campaigns and product labeling, are likely to be ineffective.

Boycunts and bonus holes: trans men's bodies, neoliberalism, and the sexual productivity of genitals.

Science.gov (United States)

Edelman, Elijah Adiv; Zimman, Lal

2014-01-01

Recent theorizations of trans embodiment have brought attention to the ways neoliberalism limits the productivity of nonnormatively gendered bodies. This article deals with the discursive framing of embodiment and sexual desirability among trans men and other transmasculine persons negotiating Internet-mediated homoerotic spaces. Micro-level analysis of discourse structure and macro-level analysis of socio-political context together show how trans men navigate homonormative sexual economies by linguistically recuperating their bodies' sexually productivity. Instead of undermining claims of embodied masculinity and homoerotic value, potential sites of exclusion-i.e., trans genitals-become sites of flexible accumulation that enhance rather than detract from their bearers' desirability.

Hippocampal sclerosis is the most common cause of drug-resistant epilepsy amenable for surgical treatment and seizure control. The rationale of the selective amygdalohippocampectomy is to spare cerebral tissue not included in the seizure generator. Describe the selective amygdalohippocampectomy through the trans-superior temporal gyrus keyhole approach. Selective amygdalohippocampectomy for temporal lobe epilepsy is performed when the data (semiology, neuroimaging, electroencephalography) point to the mesial temporal structures. The trans-superior temporal gyrus keyhole approach is a minimally invasive and safe technique that allows disconnection of the temporal stem and resection of temporomesial structures.

A Gene Gun-mediated Nonviral RNA trans-splicing Strategy for Col7a1 Repair

Directory of Open Access Journals (Sweden)

Patricia Peking

2016-01-01

Full Text Available RNA trans-splicing represents an auspicious option for the correction of genetic mutations at RNA level. Mutations within COL7A1 causing strong reduction or absence of type VII collagen are associated with the severe skin blistering disease dystrophic epidermolysis bullosa. The human COL7A1 mRNA constitutes a suitable target for this RNA therapy approach, as only a portion of the almost 9 kb transcript has to be delivered into the target cells. Here, we have proven the feasibility of 5′ trans-splicing into the Col7a1 mRNA in vitro and in vivo. We designed a 5′ RNA trans-splicing molecule, capable of replacing Col7a1 exons 1–15 and verified it in a fluorescence-based trans-splicing model system. Specific and efficient Col7a1 trans-splicing was confirmed in murine keratinocytes. To analyze trans-splicing in vivo, we used gene gun delivery of a minicircle expressing a FLAG-tagged 5′ RNA trans-splicing molecule into the skin of wild-type mice. Histological and immunofluorescence analysis of bombarded skin sections revealed vector delivery and expression within dermis and epidermis. Furthermore, we have detected trans-spliced type VII collagen protein using FLAG-tag antibodies. In conclusion, we describe a novel in vivo nonviral RNA therapy approach to restore type VII collagen expression for causative treatment of dystrophic epidermolysis bullosa.

2012-12-01

Genetic and demographic characteristics of populations from two settlements from the Aginskii Buryat district of Trans-Baikal krai (Alkhanai and Orlovskii) were studied. It was demonstrated that the mononational Buryat settlement of Alkhanai, located in the agrarian Dul'durginskii region of the district far from large settlements and transport highways, is characterized by a large prereproductive volume (45%) and by a small share of individuals from the elderly age group (16.4%). A shift in age characteristics in the Buryat group (36.6 and 22.4%, respectively) was detected in the urban settlement of Orlovskii with a population of mixed ethnic composition, located in a densely populated industrialized part of the district. A modified sex ratio was also demonstrated in Alkhanai as opposed to the Buryat part of the Orlovskii population (sex indices were 0.94 and 0.99). Analysis of population mixture was conducted; marriage structure and migrations were described. The endogamy index of the Alkhanai locality was 0.41; in the group of Buryats from Orlovskii, 0.09. A decrease in the amount of pregnancies and births and a larger distribution of family planning practice among Buryats from Orlovskii were detected. The average amount of births of living children per woman in Alkhanai was 5.11; in Buryats from Orlovskii, 3.90. The selection pressure was estimated as low by means of the Crow index (I(tot) 0.28-0.48). In all described groups, a component that characterizes differential fertility (I(f)) exceeds the child mortality component (I(m)).

District Energy Windsor

Energy Technology Data Exchange (ETDEWEB)

NONE

2002-07-01

This paper presents a summary of how District Energy Windsor operates. It includes a system site map and reasons why it is advantageous to get connected to a district heating system. District Energy Windsor is a division of the Windsor Utilities Commission. It was developed in 1996 and was the first in North America to supply both heating and cooling requirements. It supplies nearly 2 million square feet of heating and cooling for Windsor's city centre. The district energy system produces hot water or chilled water at a central plant. Energy is then piped out to buildings in the area, including the Art Gallery of Windsor, the Royal Bank Business Centre, the Windsor Justice Facility, the Windsor Casino, and Northwind Windsor. The energy, which is transferred through heat exchangers, is used for space heating, domestic hot water heating, and air conditioning. The 8 reasons for getting connected are: (1) less management costs, (2) lower energy costs, (3) lower level of risk management, (4) stable energy rates, (5) better use of building space, (6) reliable service, (7) reduced expansion costs, and (8) a cleaner environment. District heating improves air quality through reduced carbon dioxide and nitrogen oxide emissions. In addition, fuel delivery and storage are eliminated. figs.

2016-10-01

Human-assisted, trans-generational exposure to ocean warming and acidification has been proposed as a conservation and/or restoration tool to produce resilient offspring. To improve our understanding of the need for and the efficacy of this approach, we characterized life-history and physiological responses in offspring of the marine polychaete Ophryotrocha labronica exposed to predicted ocean warming (OW: + 3°C), ocean acidification (OA: pH -0.5) and their combination (OWA: + 3°C, pH -0.5), following the exposure of their parents to either control conditions ( within-generational exposure ) or the same conditions ( trans-generational exposure ). Trans-generational exposure to OW fully alleviated the negative effects of within-generational exposure to OW on fecundity and egg volume and was accompanied by increased metabolic activity. While within-generational exposure to OA reduced juvenile growth rates and egg volume, trans-generational exposure alleviated the former but could not restore the latter. Surprisingly, exposure to OWA had no negative impacts within- or trans-generationally. Our results highlight the potential for trans-generational laboratory experiments in producing offspring that are resilient to OW and OA. However, trans-generational exposure does not always appear to improve traits and therefore may not be a universally useful tool for all species in the face of global change.

Mapping neural circuits across defined synapses is essential for understanding brain function. Here we describe trans-Tango, a technique for anterograde transsynaptic circuit tracing and manipulation. At the core of trans-Tango is a synthetic signaling pathway that is introduced into all neurons in the animal. This pathway converts receptor activation at the cell surface into reporter expression through site-specific proteolysis. Specific labeling is achieved by presenting a tethered ligand at the synapses of genetically defined neurons, thereby activating the pathway in their postsynaptic partners and providing genetic access to these neurons. We first validated trans-Tango in the Drosophila olfactory system and then implemented it in the gustatory system, where projections beyond the first-order receptor neurons are not fully characterized. We identified putative second-order neurons within the sweet circuit that include projection neurons targeting known neuromodulation centers in the brain. These experiments establish trans-Tango as a flexible platform for transsynaptic circuit analysis. Copyright © 2017 Elsevier Inc. All rights reserved.

Minimally invasive endoscope-assisted trans-oral excision of huge parapharyngeal space tumors.

Li, Shang-Yi; Hsu, Ching-Hui; Chen, Mu-Kuan

2015-04-01

Parapharyngeal space tumors are rare head and neck neoplasms, and most are benign lesions. Complete excision of these tumors is difficult because of the complexity of the surrounding anatomic structures. The algorithm for excision of these tumors is typically based on the tumor's characteristics; excision is performed via approaches such as the trans-oral route, the trans-cervical route, and even a combination of the trans-parotid route and mandibulotomy. However, each of these approaches is associated with some complications. Endoscope-assisted minimally invasive surgery is being increasingly employed for surgeries in the head and neck regions. It has the advantage of leaving no facial scars, and ensures better patient comfort after the operation. Here, we report the use of endoscope-assisted trans-oral surgery for excision of parapharyngeal space tumors. The technique yields an excellent outcome and should be a feasible, safe, and economic method for these patients. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

To determine the trans fatty acids content of processed foods frequently consumed by adults living in a Rio de Janeiro, Brazil, after the enactment of a mandatory trans fatty acids labelling policy. Between February 2014 and January 2015, a specifically dietary questionnaire was completed by 107 adults to assess the frequency of processed foods consumption. The most commonly consumed products from the survey, including vegetable oils, margarine, biscuits, snacks, cheese bread (pão de queijo), french fries, cheeseburger and ice cream, were then analyzed for their trans fatty acids content using gas chromatography with a flame ionization detector. Differences in the levels of trans fatty acids were observed among 22 products analyzed, considering that trans fatty acids content ranged between 0.0 g/100 g in samples of cream cracker biscuit 1 and olive oil to 0.83 g/100 g in samples of cheeseburger (fast food), 0.51 g/100 g in samples of frozen pão de queijo and 12.92 g/100 g in samples of chocolate sandwich cookies with cream filling 2. The overall trans fatty acids content of the different samples of margarine brands was 0.20 g/100 g for brand 1 and 0.0 g/100 g for brand 2. These data are significantly lower than those observed in a survey conducted in 2003, when the regulation had been enacted. Our data indicate that Brazilian regulation is very likely implicated in the observed drop in trans fatty acids of the most processed foods but has yet to eliminate them, which reinforces the urgent need to revise the legislation, since a minimum amount of trans fat does not mean that the food product does not contain this type of fat.

In regard to [(N-heterocyclic carbene)Ru]-based catalysts, it is still a matter of debate if the substrate binding is preferentially cis or trans to the N-heterocyclic carbene ligand. By means of static and molecular dynamic DFT calculations, a simple olefin, like ethylene, is shown to be prone to the trans binding. Bearing in mind the higher reactivity of trans isomers in olefin metathesis, this insight helps to construct small alkene substrates with increased reactivity. © 2014 Springer Science+Business Media New York.

2018-02-01

Trans-methylation reactions are vital in basic metabolism, epigenetic regulation, RNA metabolism, and posttranslational control of protein function and therefore fundamental in determining the physiological processes in all living organisms. The plant kingdom is additionally characterized by the production of secondary metabolites that undergo specific hydroxylation, oxidation and methylation reactions to obtain a wide array of different chemical structures. Increasing research efforts have started to reveal the enzymatic pathways underlying the biosynthesis of complex metabolites in plants. Further engineering of these enzymatic machineries offers significant possibilities in the development of bio-based technologies, but necessitates deep understanding of their potential metabolic and regulatory interactions. Trans-methylation reactions are tightly coupled with the so-called activated methyl cycle (AMC), an essential metabolic circuit that maintains the trans-methylation capacity in all living cells. Tight regulation of the AMC is crucial in ensuring accurate trans-methylation reactions in different subcellular compartments, cell types, developmental stages and environmental conditions. This review addresses the organization and posttranslational regulation of the AMC and elaborates its critical role in determining metabolic regulation through modulation of methyl utilization in stress-exposed plants. © 2017 Scandinavian Plant Physiology Society.

The aim of this study was to investigate the associations between a series of empirically known risk and protective factors and suicidality among trans people in Sweden. Participants were self-selected anonymously to a web-based survey conducted in 2014. Univariable and multivariable logistic regression analyses were performed to assess associations between contributing factors and suicide ideation in the past 12 months and lifetime suicide attempts. The analysis included 796 trans individuals, between 15 and 94 years of age, who live in Sweden. A total of 37% of respondents reported that they have seriously considered suicide during the past 12 months and 32% had ever attempted a suicide. Offensive treatment during the past three months and lifetime exposure to trans-related violence were significantly associated with suicidality. Less satisfaction with contacts with friends and acquaintances and with one's own psychological wellbeing were associated with suicide ideation in the past 12 months. Lack of practical support was associated with lifetime suicide attempts. Our findings show that suicidality is directly correlated with trans-related victimization. Preventing targeted victimization is, therefore, a key preventive intervention against this elevated suicidality.

Spliced leader dependent trans-splicing (SLTS) has been described as an important RNA regulatory process that occurs in different organisms, including the trematode Schistosoma mansoni. We identified more than seven thousand putative SLTS sites in the parasite, comprising genes with a wide spectrum of functional classes, which underlines the SLTS as a ubiquitous mechanism in the parasite. Also, SLTS gene expression levels span several orders of magnitude, showing that SLTS frequency is not determined by the expression level of the target gene, but by the presence of particular gene features facilitating or hindering the trans-splicing mechanism. Our in-depth investigation of SLTS events demonstrates widespread alternative trans-splicing (ATS) acceptor sites occurring in different regions along the entire gene body, highlighting another important role of SLTS generating alternative RNA isoforms in the parasite, besides the polycistron resolution. Particularly for introns where SLTS directly competes for the same acceptor substrate with cis-splicing, we identified for the first time additional and important features that might determine the type of splicing. Our study substantially extends the current knowledge of RNA processing by SLTS in S. mansoni, and provide basis for future studies on the trans-splicing mechanism in other eukaryotes.

Full Text Available Toxocariasis is a widespread zoonosis and is considered an important worldwide public health problem. The aim of this study was to investigate the frequency of trans-mammary Toxocara canis infection in newborn BALB/c mice nursed by females experimentally infected with 1,200 eggs after delivery. After 50 days of age, the presence of larvae in different organs of the offspring was investigated. Trans-mammary infection was confirmed in 73.9% of the mice that had been nursed by infected females. These data show a high trans-mammary transmission of T. canis and confirm the significance of this transmission route in paratenic hosts.

2017-03-01

Full Text Available The level of education and its response to different educational opportunities vary from one spatial unit to another depending on various factors like social, economic, cultural, and institutional. It is understood that certain regions acquire relative advancements over others in terms of human resource development and human capital formation. The key purpose of this research is to examine the intra-district disparities in primary education in Bankura District one of the districts of West Bengal. It ranks 11thamong the 19 districts of West Bengal (Human Development Report, 2007.  Overall literacy rate of the district stands at 70.26% but the district scores low in terms of female literacy rates, which is 60.05%,whereas the male literacy rate is 80.05%, which is a huge gender literacy gap of 20%. There are also regional inequalities existing at block level. Kotulpur ranks first with a literacy rate of 78.01% while Saltora occupies the bottom position with literacy rate of just 61.45% (Census of India, 2011. The level of educational development is dependent on several factors—enrolment ratio, dropout and repetition rates, pupil-teacher ratio, habitations covered by educational institutions, space-student ratio, drinking water and sanitation facilities in school, etc. In this context, the present study aims at examining the issues of intra-district disparities in educational attainment with regard to various educational amenities of Bankura district, West Bengal. Ten attributes have been selected to examine the level of development in primary education. It is clear from the study that the level of development in eastern part of the district is relatively better in comparison to other regions. Economic backwardness and physical bottlenecks continue to be major issues in western blocks.

2015-01-01

Interdisciplinarity has seemingly become a paradigm for modern and meaningful research. Clearly, the interdisciplinary modus of deliberation enables to unfold relevant but quite different disciplinary perspectives to the reflection of broader scientific questions or societal problems. However, whether the comprehensive results of interdisciplinary reflection prove to be valid or to be acceptable in trans-disciplinary terms depends upon certain preconditions, which have to be fulfilled for securing scientific quality and social trust in advisory contexts. The present book is written by experts and practitioners of interdisciplinary research and policy advice. It analyses topical and methodological approaches towards interdisciplinarity, starting with the current role of scientific research in society. The volume continues with contributions to the issues of knowledge and acting and to trans-disciplinary deliberation. The final conclusions address the scientific system as substantial actor itself as well as the...

Sequential analysis of trans-SNARE formation in intracellular membrane fusion.

Directory of Open Access Journals (Sweden)

Kannan Alpadi

2012-01-01

Full Text Available SNARE complexes are required for membrane fusion in the endomembrane system. They contain coiled-coil bundles of four helices, three (Q(a, Q(b, and Q(c from target (t-SNAREs and one (R from the vesicular (v-SNARE. NSF/Sec18 disrupts these cis-SNARE complexes, allowing reassembly of their subunits into trans-SNARE complexes and subsequent fusion. Studying these reactions in native yeast vacuoles, we found that NSF/Sec18 activates the vacuolar cis-SNARE complex by selectively displacing the vacuolar Q(a SNARE, leaving behind a Q(bcR subcomplex. This subcomplex serves as an acceptor for a Q(a SNARE from the opposite membrane, leading to Q(a-Q(bcR trans-complexes. Activity tests of vacuoles with diagnostic distributions of inactivating mutations over the two fusion partners confirm that this distribution accounts for a major share of the fusion activity. The persistence of the Q(bcR cis-complex and the formation of the Q(a-Q(bcR trans-complex are both sensitive to the Rab-GTPase inhibitor, GDI, and to mutations in the vacuolar tether complex, HOPS (HOmotypic fusion and vacuolar Protein Sorting complex. This suggests that the vacuolar Rab-GTPase, Ypt7, and HOPS restrict cis-SNARE disassembly and thereby bias trans-SNARE assembly into a preferred topology.

Transmutation of a trans-series: the Gross-Witten-Wadia phase transition

Science.gov (United States)

Ahmed, Anees; Dunne, Gerald V.

2017-11-01

We study the change in the resurgent asymptotic properties of a trans-series in two parameters, a coupling g 2 and a gauge index N, as a system passes through a large N phase transition, using the universal example of the Gross-Witten-Wadia third-order phase transition in the unitary matrix model. This transition is well-studied in the immediate vicinity of the transition point, where it is characterized by a double-scaling limit Painlevé II equation, and also away from the transition point using the pre-string difference equation. Here we present a complementary analysis of the transition at all coupling and all finite N, in terms of a differential equation, using the explicit Tracy-Widom mapping of the Gross-Witten-Wadia partition function to a solution of a Painlevé III equation. This mapping provides a simple method to generate trans-series expansions in all parameter regimes, and to study their transmutation as the parameters are varied. For example, at any finite N the weak coupling expansion is divergent, with a non-perturbative trans-series completion; on the other hand, the strong coupling expansion is convergent, and yet there is still a non-perturbative trans-series completion. We show how the different instanton terms `condense' at the transition point to match with the double-scaling limit trans-series. We also define a uniform large N strong-coupling expansion (a non-linear analogue of uniform WKB), which is much more precise than the conventional large N expansion through the transition region, and apply it to the evaluation of Wilson loops.

Merlo, Caitlin L; Michael, Shannon; Brener, Nancy D; Blanck, Heidi

2018-06-07

State agencies play a critical role in providing school districts with guidance and technical assistance on school nutrition issues, including food and beverage marketing practices. We examined associations between state-level guidance and the policies and practices in school districts regarding food and beverage marketing and promotion. State policy guidance was positively associated with districts prohibiting advertisements for junk food or fast food restaurants on school property. Technical assistance from states was negatively associated with 2 district practices to restrict marketing of unhealthy foods and beverages, but positively associated with 1 practice to promote healthy options. These findings may help inform the guidance that states provide to school districts and help identify which districts may need additional assistance to address marketing and promotion practices.

2016-01-01

The rise of queer and transgender studies has greatly contributed to feminist and lesbian understandings of sex, gender, and sexuality and also has resulted in rifts, tensions, and border wars. One such tension is around the inclusion of trans women in women-only space, such as the Michigan Womyn's Music Festival (Michfest). In this ethnophenomenological study, we interviewed and surveyed 43 cisgender women who attended Michfest in 2013. Participants had a variety of perspectives on trans inclusion and on the dialogue surrounding it, and these paralleled intersections, frictions, and tensions between feminism, queer theory, and transgender studies.

Trans-fatty acid consumption and heart rate variability in two separate cohorts of older and younger adults

Background Trans-fatty acid (TFA) consumption is associated with risk of coronary heart disease, and trans-18:2, but not trans-18:1, in red blood cells membranes has been associated with sudden cardiac arrest. Abnormal heart rate variability (HRV) reflects autonomic dysfunction and predicts cardiac death. Relationships between TFA consumption and HRV remain under-studied. We determined whether total TFA consumption, as well as trans-18:1 and trans-18:2 TFA consumption, were independently associated with HRV in two independent cohorts in the US and Portugal. Methods and Results In two independent cohorts of older US adults (Cardiovascular Health Study ([CHS], age=72±5yrs, 1989/1995) and young Portuguese adults (Porto, age=19±2yrs, 2008/2010), we assessed habitual TFA intake by food frequency questionnaires in CHS (separately estimating trans-18:1 and trans-18:2) and multiple 24-hour recalls in Porto (estimating total TFA only, which in a subset correlated with circulating trans-18:2, but not trans-18:1, suggesting that we captured the former). HRV was assessed using 24-hour Holters in CHS (N=1,076) and repeated short-term (5-min) ECGs in Porto (N=160). We used multivariate-adjusted linear regression to relate TFA consumption to HRV cross-sectionally (CHS, Porto) and longitudinally (CHS). In CHS, higher trans-18:2 consumption was associated with lower 24-hour standard-deviation-of-all-normal-to-normal-intervals (SDNN) both cross-sectionally (−12%, 95%CI=6–19%, p=0.001) and longitudinally (−15%, 95%CI=4–25 %, p= 0.009), and lower 24-hour SDANN and SDNN-index (pHRV, in particular time-domain indices (SDNN, SDANN, SDNN-index; pHRV in both older and young adults. Trans-18:1 consumption is associated with more favorable HRV indices in older adults. Our results support the need to investigate potential HRV related mechanisms whereby trans-18:2 may increase arrhythmic risk. PMID:22772898

Novel 9-cis/all-trans β-carotene isomerases from plastidic oil bodies in Dunaliella bardawil catalyze the conversion of all-trans to 9-cis β-carotene.

Science.gov (United States)

Davidi, Lital; Pick, Uri

2017-06-01

We identified and demonstrated the function of 9-cis/all-trans β-carotene isomerases in plastidic globules of Dunaliella bardawil, the species accumulating the highest levels of 9-cis β-carotene that is essential for humans. The halotolerant alga Dunaliella bardawil is unique in that it accumulates under light stress high levels of β-carotene in plastidic lipid globules. The pigment is composed of two major isomers: all-trans β-carotene, the common natural form of this pigment, and 9-cis β-carotene. The biosynthetic pathway of β-carotene is known, but it is not clear how the 9-cis isomer is formed. We identified in plastidic lipid globules that were isolated from D. bardawil two proteins with high sequence homology to the D27 protein-a 9-cis/all-trans β-carotene isomerase from rice (Alder et al. Science 335:1348-1351, 2012). The proteins are enriched in the oil globules by 6- to 17-fold compared to chloroplast proteins. The expression of the corresponding genes, 9-cis-βC-iso1 and 9-cis-βC-iso2, is enhanced under light stress. The synthetic proteins catalyze in vitro conversion of all-trans to 9-cis β-carotene. Expression of the 9-cis-βC-iso1 or of 9-cis-βC-iso2 genes in an E. coli mutant line that harbors β-carotene biosynthesis genes enhanced the conversion of all-trans into 9-cis β-carotene. These results suggest that 9-cis-βC-ISO1 and 9-cis-βC-ISO2 proteins are responsible for the formation of 9-cis β-carotene in D. bardawil under stress conditions.

Brown, Neil A; Urban, Martin; Hammond-Kosack, Kim E

2016-01-01

Modern society and global ecosystems are increasingly under threat from pathogens, which cause a plethora of human, animal, invertebrate and plant diseases. Of increasing concern is the trans-kingdom tendency for increased pathogen virulence that is beginning to emerge in natural, clinical and agricultural settings. The study of pathogenicity has revealed multiple examples of convergently evolved virulence mechanisms. Originally described as rare, but increasingly common, are interactions where a single gene deletion in a pathogenic species causes hypervirulence. This review utilised the pathogen-host interaction database (www.PHI-base.org) to identify 112 hypervirulent mutations from 37 pathogen species, and subsequently interrogates the trans-kingdom, conserved, molecular, biochemical and cellular themes that cause hypervirulence. This study investigates 22 animal and 15 plant pathogens including 17 bacterial and 17 fungal species. Finally, the evolutionary significance and trans-kingdom requirement for negative regulators of hypervirulence and the implication of pathogen hypervirulence and emerging infectious diseases on society are discussed. © FEMS 2015.

Full Text Available OBJECTIVE: To analyze the monounsaturated and polyunsaturated trans fatty acid intake among the general population. METHODS: A cross-sectional study was conducted in São Paulo, Southeastern Brazil, in 2003, on a representative sample of 2,298 male and female subjects, including 803 adolescents (12 to 19 years, 713 adults (20 to 59 years and 782 elderly people (60 years or over. Food intake was measured using 24-hour recall. Mean trans fatty acid intake was described according to gender and age group. RESULTS: The mean trans fatty acid intake was 5.0 g/day (SE = 0.1, accounting for 2.4% (SE = 0.1 of total energy and 6.8% (SE = 0.1 of total lipids. The adolescents had the highest mean intake levels (7.4 g/day; 2.9% of energy while the adults and the elderly had similar intake (2.2% of energy for both; 6.4% of lipids and 6.5% of lipids, respectively. The mean trans fatty acid intake among adult and elderly women (approximately 2.5% of energy and 7.0% of lipids was higher than among men in the same age group. The food item with the highest contribution towards trans fatty acids was margarine, accounting for more than 30% of total intake, followed by filled cookies among adolescents and meat among adults and the elderly. CONCLUSIONS: The trans fatty acid intake is above the level recommended by the World Health Organization. Replacement of the trans fatty acids in manufactured food items may be an effective measure for reducing trans fatty acid intake in Brazil.OBJETIVO: Analizar el consumo de ácidos grasos moninsaturados y polinsaturados de configuración trans en la población general.

Due to the recently uncovered health benefits and anti-HIV activities of dicaffeoylquinic acids (diCQAs), understanding their structures and functions is of great interest for drug discovery efforts. DiCQAs are analytically challenging to identify and quantify since they commonly exist as a diverse mixture of positional and geometric (cis/trans) isomers. In this work, we utilized ion mobility spectrometry coupled with mass spectrometry to separate the various isomers before and after UV irradiation. The experimental collision cross sections were then compared with theoretical structures to differentiate and identify the diCQA isomers. Our analyses found that naturally the diCQAs existed predominantly as trans/trans isomers, but after 3 h of UV irradiation, cis/cis, cis/trans, trans/cis, and trans/trans isomers were all present in the mixture. This is the first report of successful differentiation of cis/trans diCQA isomers individually, which shows the great promise of IMS coupled with theoretical calculations for determining the structure and activity relationships of different isomers in drug discovery studies.

The crystals belonged to the orthorhombic space group P2 1 2 1 2 1 and diffracted to 1.44 Å resolution. The antibiotic bacillaene is biosynthesized in Bacillus subtilis by a hybrid type 1 modular polyketide synthase/nonribosomal peptide synthetase of the trans-acyltransferase (trans-AT) class. Within this system, the essential acyl-group loading activity is provided by the action of three free-standing trans-acting acyltransferases. Here, the recombinant expression, purification and crystallization of the bacillaene synthase trans-acting acyltransferase PksC are reported. A diffraction data set has been collected from a single PksC crystal to 1.44 Å resolution and the crystal was found to belong to the orthorhombic space group P2 1 2 1 2 1

Reinstating district nursing: A UK perspective.

Science.gov (United States)

Morris, Hannah

2017-09-01

As policy directives gather pace for service provision to be delivered in primary care, district nursing has not been recognised as a valuable asset to facilitate this agenda. Investment in district nursing and specialist district nursing education has fallen. This is concurrent with an ageing district nursing workforce, a lack of recruitment and growing caseloads, as district nursing adapts to meet the challenges of the complexities of contemporary healthcare in the community. The district nurse role is complex and multifaceted and includes working collaboratively and creatively to coordinate care. Redressing the shortages of specialist district nurse practitioners with increased numbers of health care support workers will not replace the skill, knowledge, experience required to meet the complex care needs of today's society. District nursing needs to be reinstated as the valuable asset it is, through renewed investment in the service, research development and in specialist practice education. To prevent extinction district nurses need to be able to demonstrate and articulate the complexities and dynamisms of the role to reinstate themselves to their commissioners as a valuable asset for contemporary practice that can meet current health and social care needs effectively.

Attention modulates trans-saccadic integration.

Stewart, Emma E M; Schütz, Alexander C

With every saccade, humans must reconcile the low resolution peripheral information available before a saccade, with the high resolution foveal information acquired after the saccade. While research has shown that we are able to integrate peripheral and foveal vision in a near-optimal manner, it is still unclear which mechanisms may underpin this important perceptual process. One potential mechanism that may moderate this integration process is visual attention. Pre-saccadic attention is a well documented phenomenon, whereby visual attention shifts to the location of an upcoming saccade before the saccade is executed. While it plays an important role in other peri-saccadic processes such as predictive remapping, the role of attention in the integration process is as yet unknown. This study aimed to determine whether the presentation of an attentional distractor during a saccade impaired trans-saccadic integration, and to measure the time-course of this impairment. Results showed that presenting an attentional distractor impaired integration performance both before saccade onset, and during the saccade, in selected subjects who showed integration in the absence of a distractor. This suggests that visual attention may be a mechanism that facilitates trans-saccadic integration. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

Excess consumption of trans-fatty acid could increase the risk of non-alcoholic steatohepatitis (NASH); however, treatment targeting trans-fatty acid-induced NASH has not been examined. Here we focused on the influence of trans-fatty acid intake on endoplasmic reticulum (ER) stress in hepatocytes, so we investigated the effect of the chemical chaperone 4-phenylbutyric acid (PBA), on trans-fatty acid-caused steatohepatitis using diabetic KK-A(y) mice. Elaidic acid (EA, trans-fatty acid) alone did not cause definitive liver injury. In contrast, EA plus low-dose fructose induced extensive apoptosis in hepatocytes with severe fat accumulation. EA plus fructose significantly increased ER stress markers such as glucose-regulated protein 78 (GRP78), eukaryotic initiation factor 2α (eIF2α) and phosphorylated c-jun N-terminal kinase (JNK), while PBA significantly reduced this response. In vitro, EA promoted expression of GRP78 and phosphorylation of eIF2α in primary-cultured hepatocytes. EA also increased hepatocellular susceptibility to low-dose tert-butyl hydroperoxide. Treatment with PBA significantly reduced these responses. In conclusion, EA potentiates susceptibly to non-hazardous dose of fructose, and increases ER and oxidative stress. PBA improved steatohepatitis induced by EA plus fructose through amelioration of ER stress. Therefore, ER stress-targeted therapy using a chemical chaperone is a promising novel strategy for trans-fatty acid-induced steatohepatitis.

This paper deals with lightlike hypersurfaces of indefinite trans-Sasakian manifolds of type (α, β), tangent to the structure vector field. Characterization Theorems on parallel vector fields, integrable distributions, minimal distributions, Ricci-semi symmetric, geodesibility of lightlike hypersurfaces are obtained. The geometric configuration of lightlike hypersurfaces is established. We prove, under some conditions, that there are no parallel and totally contact umbilical lightlike hypersurfaces of trans-Sasakian space forms, tangent to the structure vector field. We show that there exists a totally umbilical distribution in an Einstein parallel lightlike hypersurface which does not contain the structure vector field. We characterize the normal bundle along any totally contact umbilical leaf of an integrable screen distribution. We finally prove that the geometry of any leaf of an integrable distribution is closely related to the geometry of a normal bundle and its image under φ-bar. (author)

Introduction to Trans Australia Airlines CRM training

Science.gov (United States)

Davidson, Jim

1987-01-01

Trans Australia believes that its excellent accident rate record is due to a number of factors. It has a good group of standard operating procedures, and its crews are pretty well self-disciplined and adhere to those procedures. But the other thing that it believes is a factor in its safety record is that perhaps it is also due to its preparedness to be innovative, to keep up with what is going on in the rest of the world and, if it looks to have value, then to be amongst the first to try it out. Trans Australia commenced a program similar to Line Oriented Flight Training (LOFT) fairly early in 1979--that being its first windshear program-- which leads to why they are doing a course of resource management training, which we have chosen to call Aircrew Team Management (ATM). This course is detailed in another presentation.

Corrosion of silicon-containing austenitic stainless steels under trans-passive conditions

International Nuclear Information System (INIS)

Stolarz, Jacek

1989-01-01

This research thesis addresses austenitic stainless steels which are used in installations for the chemical treatment of nuclear fuels, and are there in contact with nitric acid solutions the oxidising character of which generally promotes metal passivity. However, if this nitric environment becomes too oxidising, these steels may face severe corrosion problems. More particularly, this thesis addresses the study of intergranular corrosion, and aims at analysing various aspects of the corrosion of these austenitic stainless steels in trans-passive conditions. The author aims at determining and distinguishing the contributions due to silicon and those related to the presence of other impurities and addition elements by comparing the behaviours of industrial grade steels and high purity alloys in rigorously controlled electrochemical conditions. Another objective is to study the influence of the intergranular structure on silicon segregation by means of an attack technique in trans-passive conditions. After a report of a bibliographical study on the addressed topics and a presentation of the studied materials and implemented experimental techniques, the author reports the study of steel behaviour with respect to generalised dissolution in trans-passive conditions, as well in the nitric environment as in a sulphuric acid solution at imposed potential. Localised intragranular corrosion phenomena are discussed. A trans-passive intragranular corrosion model is proposed, and its possibilities in the analysis of intergranular segregation analysis are discussed. Experimental results of trans-passive intergranular corrosion of stainless steels are presented and interpreted by using the McLean segregation model. The influence of steel composition and of experimental conditions is discussed, as well as the role of grain boundary structure in the corrosion process [fr

As referrals to gender identity clinics have increased dramatically over the last few years, no studies focusing on older trans people seeking treatment are available. The aim of this study was to investigate the sociodemographic and clinical characteristics of older trans people attending a national service and to investigate the influence of cross-sex hormones (CHT) on psychopathology. Individuals over the age of 50 years old referred to a national gender identity clinic during a 30-month period were invited to complete a battery of questionnaires to measure psychopathology and clinical characteristics. Individuals on cross-sex hormones prior to the assessment were compared with those not on treatment for different variables measuring psychopathology. Sociodemographic and clinical variables and measures of depression and anxiety (Hospital Anxiety and Depression Scale), self-esteem (Rosenberg Self-Esteem Scale), victimization (Experiences of Transphobia Scale), social support (Multidimensional Scale of Perceived Social Support), interpersonal functioning (Inventory of Interpersonal Problems), and nonsuicidal self-injury (Self-Injury Questionnaire). The sex ratio of trans females aged 50 years and older compared to trans males was 23.7:1. Trans males were removed for the analysis due to their small number (n = 3). Participants included 71 trans females over the age of 50, of whom the vast majority were white, employed or retired, and divorced and had children. Trans females on CHT who came out as trans and transitioned at an earlier age were significantly less anxious, reported higher levels of self-esteem, and presented with fewer socialization problems. When controlling for socialization problems, differences in levels of anxiety but not self-esteem remained. The use of cross-sex hormones prior to seeking treatment is widespread among older trans females and appears to be associated with psychological benefits.

This article reports the results of a study, conducted in the framework of the scientific activities of the Italian Society for Reference Values, aimed at defining reference values of urinary trans,trans-muconic acid (t,t-MA) in the general population not occupationally exposed to benzene. t,t-MA concentrations detected in 376 subjects of the resident population in three areas of Italy, two in central (Florence and southern Tuscany) and one in northern Italy (Padua), by three laboratories, compared by repeated interlaboratory controls, showed an interval of 14.4-225.0 microg/L (5th-95th percentile) and a geometric mean of 52.5 microg/L. The concentrations measured were influenced by tobacco smoking in a statistically significant way: Geometric mean concentrations were 44.8 microg/L and 76.1 microg/Ll in nonsmokers (264 subjects) and smokers (112 subjects), respectively. In the nonsmoking population, a significant influence of gender was found when concentrations were corrected for urinary creatinine, geometric mean concentrations being 36.7 microg/g creatinine in males (128 subjects) and 44.7 microg/g creatinine in females (136 subjects). The place of residence of subjects did not seem to influence urinary excretion of the metabolite, although personal inhalation exposure to benzene over a 24-h period showed slightly higher concentrations in Padua and Florence (geometric means of 6.5 microg/m(3) and 6.6 microg/m(3), respectively) than in southern Tuscany (geometric mean of 3.9 microg/m(3)). Concentration of t,t-MA in urine samples collected at the end of personal air sampling showed little relationship to personal inhalation exposure to benzene, confirming the importance of other factors in determining excretion of t,t-MA when concentrations in personal air samples are very low.

District Fiscal Policy and Student Achievement

Full Text Available School restructuring raises questions about the role of school districts in improving student learning. Centralization by state governments and decentralization to individual schools as proposed in systemic reform leave districts' role unsettled. Empirical research on the district role in the context of ongoing reform is inadequate. This analysis of combined data from the NAEP and the Common Core of Data (CCD was intended to address the issue. We analyzed 1990, 1992, and 1996 NAEP 8th grade mathematics national assessment data in combination with CCD data of corresponding years to examine the extent to which student achievement was related to districts' control over instructional expenditure, adjusting for relevant key factors at both district and student levels. Upon sample modification, we used hierarchical linear modeling (HLM to estimate the relationships of student achievement to two district fiscal policy indictors, current expenditure per pupil (CEPP and districts' discretionary rates for instructional expenditure (DDR. Net of relevant district factors, DDR was found unrelated to districts' average 8th grade math performance. The null effect was consistent in the analysis of the combined NAEP-CCD data for 1990, 1992, and 1996. In contrast, CEPP was found related to higher math performance in a modest yet fairly consistent way. Future research may be productive to separately study individual states and integrate the findings onto the national level.

Trans-resveratrol is widely studied for its potentially beneficial effects on numerous disorders. It is rapidly metabolized and its metabolites can exhibit biological activity. The present study aimed to investigate whether acute or sustained trans-resveratrol administration impacted on the distribution of trans-resveratrol and its metabolites in brain, heart, and liver. We used ultra-HPLC quadrupole-TOF (UHPLC-Q-TOF) in a full-scan mode to identify and assess large numbers of resveratrol metabolites. For acute intake, mice were overfed with a single dose of trans-resveratrol (150 mg/kg) and organs were collected after 30 and 60 min. For sustained intake, trans-resveratrol was given in the chow (0.04% w/w corresponding to 40 mg/kg/day), and plasma and the organs were collected after 3 months of this resveratrol diet. We found that trans-resveratrol-3-O-glucuronide and resveratrol-3-sulfate were the main metabolites found after acute intake, and free trans-resveratrol (in the brain and heart) and dihydroresveratrol derivatives were found after sustained administration CONCLUSIONS: Our results show notable differences between acute and sustained administration of trans-resveratrol and distribution of trans-resveratrol and its metabolites in mouse heart, brain, and liver. The results suggest a strategy for development of galenic forms of resveratrol. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Effect of ultrasonic waves on the stability of all-trans lutein and its degradation kinetics.

Song, Jiang-Feng; Li, Da-Jing; Pang, Hui-Li; Liu, Chun-Quan

2015-11-01

Ultrasound treatment has been widely applied in the extraction of biologically active compounds including carotenoids. However, there are few reports on their effects on the stability of these compounds. In the present study, the stability of all-trans lutein, one of the carotenoids, was investigated under the action of ultrasound. Results showed that ultrasound induced the isomerization of all-trans lutein to its isomers, namely to 13-cis lutein, 13'-cis lutein, 9-cis lutein and 9'-cis lutein as analyzed by HPLC coupled with DAD and LC-MS; and the percentage of the isomerization increased with increasing both ultrasonic frequency and power. The stability of all-trans lutein in dichloromethane was worst among multiple kinds of solvents. Interestingly, the retention rate of all-trans lutein improved as the temperature increased, which runs counter to the Arrhenius law. Under ultrasound irradiation, the degradation mechanism might be different with various temperatures, the degradation of all-trans lutein followed first-order kinetics at 20°C, while second-order kinetics was followed at 30-50°C. As the ultrasonic reaction time prolonged, lutein epoxidation nearly occurred. Those results presented here emphasized that UAE techniques should be carefully used in the extraction of all-trans lutein. Copyright © 2015 Elsevier B.V. All rights reserved.

Calderas and mineralization: volcanic geology and mineralization in the Chianti caldera complex, Trans-Pecos Texas

Energy Technology Data Exchange (ETDEWEB)

Duex, T.W.; Henry, C.D.

1981-01-01

This report describes preliminary results of an ongoing study of the volcanic stratigraphy, caldera activity, and known and potential mineralization of the Chinati Mountains area of Trans-Pecos Texas. Many ore deposits are spatially associated with calderas and other volcanic centers. A genetic relationship between calderas and base and precious metal mineralization has been proposed by some and denied by others. Steven and others have demonstrated that calderas provide an important setting for mineralization in the San Juan volcanic field of Colorado. Mineralization is not found in all calderas but is apparently restricted to calderas that had complex, postsubsidence igneous activity. A comparison of volcanic setting, volcanic history, caldera evolution, and evidence of mineralization in Trans-Pecos to those of the San Juan volcanic field, a major mineral producer, indicates that Trans-Pecos Texas also could be an important mineralized region. The Chianti caldera complex in Trans-Pecos Texas contains at least two calderas that have had considerable postsubsidence activity and that display large areas of hydrothermal alteration and mineralization. Abundant prospects in Trans-Pecos and numerous producing mines immediately south of the Trans-Pecos volcanic field in Mexico are additional evidence that ore-grade deposits could occur in Texas.

In recent decades, the increased consumption of processed foods, which are rich in hydrogenated vegetable fat (HVF), has led to a decreased consumption of fish and oilseed, rich in omega-3 fatty acids. This eating habit provides an increased intake of trans fatty acids (TFA), which may be related to neuropsychiatric conditions, including inattention and hyperactivity. In this study, we evaluated the potential connection between prolonged trans fat consumption and development of hyperactivity-like symptoms in rats using different behavioral paradigms. Trans fat intake for 10 months (Experiment 1), as well as during pregnancy and lactation across two sequential generations of rats, (Experiment 4) induced active coping in the forced swimming task (FST). In addition, HVF supplementation was associated with increased locomotion before and after amphetamine (AMPH) administration (Experiment 2). Similarly, HVF supplementation during pregnancy and lactation were associated with increased locomotion in both young and adult rats (Experiment 3). Furthermore, trans fat intake across two sequential generations increased locomotor and exploratory activities following stressors (Experiment 4). From these results, we suggest that chronic consumption of trans fat is able to enhance impulsiveness and reactivity to novelty, facilitating hyperactive behaviors. Copyright © 2014 Elsevier Inc.

To assess effects of heated edible oils on intake of trans fatty acids (TFAs); the formation of TFAs in cooking conditions was investigated by a frying system model, in which chicken fillet was fried in a commercial corn oil at 170 °C, for 12 frying cycles. The main TFAs detected in chicken fillet were trans C18:2 fatty acids (FAs) and trans C18:3 FAs, which exhibited no significant differences among the frying cycles. Besides, the content of trans C18:1 FAs were very low in all samples on different frying cycles. The intake of TFAs was estimated to be 0.06 g/100 g when chicken fillet fried in this process was consumed. These results suggest that an ordinary frying process upon a commercial corn oil has little impact on the daily TFAs intake.

Breaking down barriers: exploring the potential for social care practice with trans survivors of domestic abuse.

Science.gov (United States)

Rogers, Michaela

2016-01-01

There is increasing recognition that domestic abuse takes place outside the heteronormative paradigm of social life. This paper presents a discussion of the findings of doctoral research which explores trans people's experiences of domestic abuse, their social care needs and whether these are met by domestic abuse agencies. This paper foregrounds debate on the intersections of domestic abuse, trans communities and social care provision as this research, and previous studies, suggests that trans survivors do not seek out or benefit from social care intervention. Qualitative data, collected via narrative interviews, were collected during 2012 from participants mainly located in the United Kingdom (two participants were based in the United States). A total of 24 interviews were undertaken with trans people (n = 15) and social care practitioners (n = 9). Data were examined using a voice-centred relational technique. The findings reveal that barriers are multiple and complex but work could be undertaken to encourage help-seeking behaviours. Barriers include expectations of a transphobic response and 'Othering' practices; lack of entitlement felt by trans people; lack of knowledge/misunderstandings about trans social care needs; heteronormative bias of existing services; and practitioner attitudes fixed to notions about gender as binary. The paper ends by proposing a framework for practice with trans survivors which incorporates a person-centred, narrative approach. © 2015 John Wiley & Sons Ltd.

The synthesis of (±)- [1,1'- 15 N 2 , 2'- 13 C]-trans-3'-methylnicotine is reported. 15 N-3-Bromopyridine obtained from bromination of pyridine was formylated with nBuLi/[carbonyl- 13 C]-methyl formate. The resulting 15 n-Pyridine-3-[ 13 C-carbonyl]-carboxaldehyde was reacted with 15 N-methylamine and then the resulting Schiff's base was condensed with succinic anhydride to give (±)- [1,1'- 15 N 2 , 5'- 13 C]-trans-4'-carboxycotinine. Reduction with lithium aluminum hydride and mesylation followed by reduction with Zn/NaI gave (±)-[1,1'- 15 N 2 , 2'- 13 C]-trans-3'-methylnicotine. (Author)

Identifying transcription factor (TFs) cooperation controlling target gene expression is still an arduous challenge. The accuracy of current methods at genome scale significantly drops with the increase in number of genes, which limits their applicability to more complex genomes, like animals and plants. Here, we developed an algorithm, TransDetect, able to predict TF combinations controlling the expression level of a given gene. TransDetect was used to identify novel TF modules regulating the expression of Arabidopsis ( Arabidopsis thaliana ) phosphate transporter PHO1;H3 comprising MYB15, MYB84, bHLH35, and ICE1. These TFs were confirmed to interact between themselves and with the PHO1;H3 promoter. Phenotypic and genetic analyses of TF mutants enable the organization of these four TFs and PHO1;H3 in a new gene regulatory network controlling phosphate accumulation in zinc-dependent manner. This demonstrates the potential of TransDetect to extract directionality in nondynamic transcriptomes and to provide a blueprint to identify gene regulatory network involved in a given biological process. © 2017 American Society of Plant Biologists.

Trans-European transport networks and urban systems in European Union

Directory of Open Access Journals (Sweden)

2003-01-01

Full Text Available The trans-European transport network has different effects at interregional macro-regional and mezzo-regional level, and its effectiveness rises at the lower regional levels. Possible approaches to the trans-European transport network impact and effect survey and policy options have been pointed out. In that respect the brief review of survies, strategic framework and policies in European Union has been given. The importance of increased accessibility and mobility for regional expansion and for more balanced and polycentric system of city networks has been underlined. The question is how the new major transport infrastructure affects the development of functional complementarity between cities and regions. The new trans-European or major transport infrastructure does not per se create regional and urban system network development, although it can affect the conditions for the processes that create growth and development. The effects can be increased by co-ordination of measures of regional and urban policy, land use, transport and other policies. The necessary measure is the introduction of spatial impact assessment as sectorial policy instrument for the large transport infrastructure projects.

Challenges of implementing collaborative models of decision making with trans-identified patients.

Science.gov (United States)

Dewey, Jodie M

2015-10-01

Factors health providers face during the doctor-patient encounter both impede and assist the development of collaborative models of treatment. I investigated decision making among medical and therapeutic professionals who work with trans-identified patients to understand factors that might impede or facilitate the adoption of the collaborative decision-making model in their clinical work. Following a grounded theory approach, I collected and analysed data from semi-structured interviews with 10 U.S. physicians and 10 U.S. mental health professionals. Doctors and therapists often desire collaboration with their patients but experience dilemmas in treating the trans-identified patients. Dilemmas include lack of formal education, little to no institutional support and inconsistent understanding and application of the main documents used by professionals treating trans-patients. Providers face considerable risk in providing unconventional treatments due to the lack of institutional and academic support relating to the treatment for trans-people, and the varied interpretation and application of the diagnostic and treatment documents used in treating trans-people. To address this risk, the relationship with the patient becomes crucial. However, trust, a component required for collaboration, is thwarted when the patients feel obliged to present in ways aligned with these documents in order to receive desired treatments. When trust cannot be established, medical and mental health providers can and do delay or deny treatments, resulting in the imbalance of power between patient and provider. The documents created to assist in treatment actually thwart professional desire to work collaboratively with patients. © 2013 John Wiley & Sons Ltd.

Excessive bleeding is an unwanted complication of trans-sphenoidal resection of pituitary adenoma due to increases in intracranial pressure (ICP) and hemodynamic instability. Dexmedetomidine (Dex) anα2-agonists is the drug of choice in intensive care units (ICU) and cardiac surgeries to control abrupt changes in hemodynamic. Severe cardiovascular responses occur during trans-sphenoidal resection (TSR) of the pituitary adenoma despite adequate depth of anesthesia. The aim of this paper was to determine the effect of Dexmedetomidine on bleeding as primary outcome, and surgeon's satisfaction and hemodynamic stability as secondary outcomes in patients undergoing trans-sphenoidal resection of pituitary adenoma. Total numbers of 60 patients between 18-65 years old and candidate for elective trans-sphenoidal resection of pituitary adenoma were randomLy allocated to two groups; Dexmedetomidine infusion (0.6µg/kg/hour) or normal saline infusion. Mean arterial pressure (MAP), heart rate (HR), dose of hypnotics and narcotics during surgery, bleeding, and surgeon's satisfaction were recorded. Propofol maintenance dose (µg/kg/min) and total Fentanyl use (µg) were significantly lower in Dex group compare to control group (P=0.01 and 0.003, respectively). Total bleeding amount during operation in Dex group was significantly lower than control group (P=0.012). Surgeon's satisfaction was significantly higher in Dex group at the end of surgery. MAP and heart rate throughout surgery were significantly lower in Dex group compare to control group (P=0.001). Dexmedetomidine infusion (0.6µg/kg/hour) could reduce bleeding and provide surgeon's satisfaction during trans-sphenoidal resection of pituitary adenoma.

Coevolution within a transcriptional network by compensatory trans and cis mutations

KAUST Repository

Kuo, D.

2010-10-26

Transcriptional networks have been shown to evolve very rapidly, prompting questions as to how such changes arise and are tolerated. Recent comparisons of transcriptional networks across species have implicated variations in the cis-acting DNA sequences near genes as the main cause of divergence. What is less clear is how these changes interact with trans-acting changes occurring elsewhere in the genetic circuit. Here, we report the discovery of a system of compensatory trans and cis mutations in the yeast AP-1 transcriptional network that allows for conserved transcriptional regulation despite continued genetic change. We pinpoint a single species, the fungal pathogen Candida glabrata, in which a trans mutation has occurred very recently in a single AP-1 family member, distinguishing it from its Saccharomyces ortholog. Comparison of chromatin immunoprecipitation profiles between Candida and Saccharomyces shows that, despite their different DNA-binding domains, the AP-1 orthologs regulate a conserved block of genes. This conservation is enabled by concomitant changes in the cis-regulatory motifs upstream of each gene. Thus, both trans and cis mutations have perturbed the yeast AP-1 regulatory system in such a way as to compensate for one another. This demonstrates an example of “coevolution” between a DNA-binding transcription factor and its cis-regulatory site, reminiscent of the coevolution of protein binding partners.

Structural and mechanistic analysis of trans-3-chloroacrylic acid dehalogenase activity

The X-ray structure of a noncovalently modified trans-3-chloroacrylic acid dehalogenase with a substrate-homolog acetate bound in the active site has been determined to 1.7 Å resolution. Elucidation of catalytically important water is reported and multiple conformations of the catalytic residue αGlu52 are observed. Trans-3-chloroacrylic acid dehalogenase (CaaD) is a critical enzyme in the trans-1, 3-dichloropropene (DCP) degradation pathway in Pseudomonas pavonaceae 170. This enzyme allows bacteria to use trans-DCP, a common component in commercially produced fumigants, as a carbon source. CaaD specifically catalyzes the fourth step of the pathway by cofactor-independent dehalogenation of a vinyl carbon–halogen bond. Previous studies have reported an X-ray structure of CaaD under acidic conditions with a covalent modification of the catalytic βPro1 residue. Here, the 1.7 Å resolution X-ray structure of CaaD under neutral (pH 6.5) conditions is reported without the presence of the covalent adduct. In this new structure, a substrate-like acetate molecule is bound within the active site in a position analogous to the putative substrate-binding site. Additionally, a catalytically important water molecule was identified, consistent with previously proposed reaction schemes. Finally, flexibility of the catalytically relevant side chain αGlu52 is observed in the structure, supporting its role in the catalytic mechanism.

Trans-fatty acids are present in various foods, being the only source of the same in humans. Its presence in high concentrations is a risk factor for health, being involved in a series of events, cardiovascular, inflammatory, etc. Therefore, steps have been taken for its decrease in the diet. The aim is to determine serum and phospholipids of membranes in healthy children and neurological alterations. It has analyzed the fatty acids trans in 34 healthy children and 374 with various neurological pathologies. Serum and blood cells, making the lipid extraction, samples have been separation of the phospholipids of cells membranes, methylation of fatty acids, separation by gas chromatography and quantification using mass detector. The data have been processed statistically. The distribution of trans fatty acids and their sum is not normally distributed, so its nonparemetric tests were used. The values are higher than in serum phospholipids and membrane with a weak but significant correlation. The tC18: 1 is in a double proportion in children with neurological disorders in healthy children, both in serum and membrane phospholipids, with significant differences. The highest proportion of trans-fatty acids in the group of children with neurological disorders is caused no doubt by an increase in intake, due to less adequate food.

One of the most important potential problems with modern military systems which utilize spacecraft is the effect of the ionosphere on the radio signals which pass to and from the spacecraft. Such systems include active communications and navigation satellites as well as both ground-based and potential space-based ranging systems. The major effects the ionosphere can have on such systems are the additional time delay the electrons in the earth's ionosphere add to the free space path delay, the short term rate of change of this additional delay, amplitude scintillation or fading effects the signal encounters due to irregularities in the ionosphere, and Faraday rotation of linearly polarized radio waves transmitted through the ionosphere. While some of these effects were studied adequate models of these effects on military systems still do not exist. A modern trans-ionospheric sensing system, called TISS, is being procured which will consist of a number of stations located throughout the world, making real time measurements of the time delay of the ionosphere, and its rate of change, as well as amplitude scintillation, along several different viewing directions from each station. These trans-ionospheric measurements will be used to allow models, which currently provide only monthly propagation parameters. The real-time specifications of these parameters can then be used as decision aids in both the tactical and the strategic military environments. The TISS will include first order artificial intelligence design to aid in gathering the most appropriate sets of available real-time trans-ionospheric propagation data, and will communicate these data sets to the Air Weather Service Forecasting Center where they will be tailored to specific military customers.

2001-01-01

Uranium deposits are discovered in 15 ore districts of the Russian Federation. They are subdivided into four groups: Streltsovsky district with existing production centre, Stavropolsky district with depleted deposits, three prospective districts and ten reserve districts. The overview of new data on these districts is presented. Streltsovsky district with Priargunsky Production Centre include 19 molybdenum-uranium deposits of structure-bound volcanic type in caldera. The main activities in Stavropolsky district with two depleted uranium deposits are connected with restoration works and wastes rehabilitation. Except Streltsovsky district there are no more deposits in the Russian Federation prepared for uranium production. At the same time some uranium deposits of Vitimsky, Zauralsky, and West-Siberian districts are prospective for new development of production centres. They belong to the sandstone type, related to paleovalley or basal channel, and are suitable for ISL operation. The deposits of the other districts are considered to be reserve and considered unprofitable for uranium production at present and in the nearest future. The biggest of them is Aldansky district with gold-uranium deposits in potassium metasomatites in areas of Mesozoic activation of Archean cratons. Central Transbaikalsky, Yeniseisky, Yergeninsky, Onezhsky, Ladozhsky, Bureinsky, Khankaisky, Volgo-Uralsky reserve districts include mainly small-size deposits of vein, volcanic, surficial and metasomatite types with low uranium grades.

2010-01-01

We inspected the feasibility of minimally invasive surgery for superficial esophageal cancer, the trans-hiatal approach without thoracotomy. We examined the surgical outcomes of 33 superficial esophageal cancer whose cancer had invaded the submucosal layer and who underwent resection in our hospital between April 2003 and April 2009. The patients who had tumor invasion of within the sm1 and no metastasis to the upper and middle mediastinum lymph nodes were operated on by the trans-hiatal esophagectomy (THE). The other patients were underwent ordinary trans-thoracic esophagectomy (TTE). After the operations, we recommended adjuvant chemoradiation therapy for all patients whose tumor were histopathologically proved to involve the sm2 layer as well as the vessels and/or lymphatic duct. Of our 33 cases, nine were diagnosed as pM1 or pM2. Two were diagnosed as pM3, one of which had lymph node metastasis. Eleven cases were diagnosed as pSM1, four as pSM2, and seven as pSM3; and lymph node metastasis was observed in 4 pSM1 cases (36%), 2 pSM2 cases (50%) and 5 pSM3 cases (71.4%). The five-year survival rate in all cases was 89.6%. The five-year survival rate by operating method was 100% in THE cases or 80.9% in TTE cases. The rates by tumor depth of invasion was 100% in pM1-2 cases, 92.3% in pM3-SM1 cases and 78.8% in pSM2-3 cases. It is concluded that the surgical outcome of THE in accordance with our indication criteria is equal to that of TTE for superficial esophageal cancer. (author)

The objective of this study was to investigate how environmental and structural changes to a trans outdoor work environment impacted sex workers in Vancouver, Canada. The issue of changes to the work area arose during qualitative interviews with 33 trans sex workers. In response, ethnographic walks that incorporated photography were undertaken with trans sex workers. Changes to the work environment were found to increase vulnerabilities to client violence, displace trans sex workers, and affect policing practices. Within a criminalized context, construction and gentrification enhanced vulnerabilities to violence and harassment from police and residents.

Trans-Saharan geopolitics. The game and the stakes

International Nuclear Information System (INIS)

Chegrouche, L.

2010-01-01

The geopolitics of energy exports from the trans-Saharan region are similar to the Caspian great game' at the end of the last century. In North/West Africa as in West/Central Asia, the question of control over hydrocarbon reserves and lines of access to those reserves lies at the source of various conflicts. Rivalries are expressed through open and complex conflicts in which powers confront one another over oil-rich zones through proxy ethnic, religious or cultural groups, as dictated by the colossal economic interests at stake. The increasing number of conflicts - the Niger Delta, Darfur, the Azawak, etc. - is an illustration of this. The shock waves from this rivalry undermine regional peace and security, as well as the security of international energy supplies. The question here is to understand the game and the stakes of this trans-Saharan chess-board, to study its principal features and its energetic consequences. The national oil companies and states of the region can work around or through the geopolitical rifts caused by local rivalries and extra-regional appetites. There is therefore a need to understand the ways in which the players in the trans-Saharan 'great game' interact with one another, an to identifies the effects these interactions may have in the field of energy, in terms of potential reserves and transport projects. The TSGP is presented as an illustration of this geopolitical dynamics. (author)

Full Text Available Eduardo Lourenço has focused some of his research on the historical-mythical relationship of the Portuguese with their country, claiming that they have been living in a kind of hyper-identity, incorporating an obsession with the past, which co-exists with a waiting utopian by future, as is demonstrates the Sebastianism myth. Focused on the representations of trans-temporality, identity, collective memory and myth, The Portuguese Cinema, Trans-temporality and the Myth, concentrated especially in Eduardo Lourenço's work to propose a research on how the identity myths – created and disseminated by Portuguese literature over the centuries – earned imagistic representations in the twentieth and twenty-first century’s, through a cinema that built or deconstructed these historical and patriotic mythological, inscribing image capacities to continually rebuild one mythologized common heritage.

FROM ADVANCE TO TRANS-PROFESSIONAL EDUCATION

Full Text Available Introduction. For several decades, the gap of vocational education with quickly changing realities in labour market, in the field of technologies and socio-economic sphere, and the need for the advancing vocational training, have been considered as the topical and steadily growing problems. Numerous attempts to overcome the presented above problems by means of fundamentalization and predictive methods have not led to anything so far. It is obvious that other education opportunities for in-demand, highly skilled, competitive specialists are needed.The aims of the publication are to discuss the potential of trans-professional education; to come up with arguments in favour of its introduction as the most perspective direction which might allow university and college graduates: to be guided better on labour market; to be more confident in unstable, unpredictable reality; to adapt quickly to dynamically changing situations in the world of professions.Methodology and research methods. The research paper is based on comparative analysis that provided an opportunity to find out the conceptual grounds of traditional mono-professional education and trans-professional education appropriate for challenges of modern Russia.Results and scientific novelty. It is emphasized that mono-professionalism as a paradigm reference point of professional education content is called for global reconsideration; for many years, preservation of traditional forms and methods have prevented mono-professionalism of good intentions to give it the advancing character, especially, at its initial stage.For the first time, trans-professional education has been considered as a result of considerably heterogeneous (as opposed to homogeneous bi- and polyprofessional training; the essence of that training consists in learning not related specialties concerned to one professional group, but professions that are absolutely far apart. Such approach will promote not only expansion of

ABSTRACT Background: Poor quality of care and access to effective and affordable interventions have been attributed to constraints and bottlenecks within and outside the health system. However, there is limited understanding of health system barriers to utilization and delivery of appropriate, high-impact, and cost-effective interventions at the point of service delivery in districts and sub-districts in low-income countries. In this study we illustrate the use of the bottleneck analysis approach, which could be used to identify bottlenecks in service delivery within the district health system. Methods: A modified Tanahashi model with six determinants for effective coverage was used to determine bottlenecks in service provision for maternal and newborn care. The following interventions provided during antenatal care were used as tracer interventions: use of iron and folic acid, intermittent presumptive treatment for malaria, HIV counseling and testing, and syphilis testing. Data from cross-sectional household and health facility surveys in Mayuge and Namayingo districts in Uganda were used in this study. Results: Effective coverage and human resource gaps were identified as the biggest bottlenecks in both districts, with coverage ranging from 0% to 66% for effective coverage and from 46% to 58% for availability of health facility staff. Our findings revealed a similar pattern in bottlenecks in both districts for particular interventions although the districts are functionally independent. Conclusion: The modified Tanahashi model is an analysis tool that can be used to identify bottlenecks to effective coverage within the district health system, for instance, the effective coverage for maternal and newborn care interventions. However, the analysis is highly dependent on the availability of data to populate all six determinants and could benefit from further validation analysis for the causes of bottlenecks identified.

Harris, William S; Reid, Kimberly J; Sands, Scott A; Spertus, John A

2007-01-15

We tested the hypothesis that lower blood omega-3 (omega-3) fatty acids (FAs) and/or higher trans FAs are associated with the risk of an acute coronary syndrome (ACS). Higher levels of omega-3 FA have been associated with decreased risk of sudden cardiac death. However, their association with ACS risk is unclear. Although higher self-reported intakes of trans FAs have been linked to increased coronary risk, the association between blood levels of trans FA and ACS risk is also unknown. We analyzed the FA composition of whole blood from 94 subjects with ACS and 94 age-, gender-, and race-matched controls. Omega-3 and trans FA associations with ACS were assessed using multivariable models after adjusting for smoking status, alcohol use, diabetes, body mass index, serum lipids, and history of myocardial infarction or revascularization. Subjects' mean age was 47 years, 54% were men, and 80% were Caucasian. Whole blood long-chain omega-3 FA (eicosapentaenoic acid [EPA] plus docosahexaenoic acid [DHA]) content was 29% lower in patients than in controls (1.7 +/- 0.9% vs 2.4 +/- 1.4%, p ACS, but higher blood trans FA content is not. Blood EPA + DHA may serve as a new, modifiable risk factor for ACS.

Trans-Disciplinary Education for Sustainable Marine and Coastal Management: A Case Study in Taiwan

2016-10-01

Full Text Available The present study aims to investigate the effect of a trans-disciplinary design of curricula, deemed a powerful tool for teaching and research on complex environmental problems, with a goal to help solve the real problems that climate change has brought to the coastal environment in Taiwan. Three major real-life problems in southern Taiwan—declining mullet fisheries, flooding, and coral bleaching—were integrated into four courses. Adopting a qualitative case study method, the researchers investigated the student perceptions of the trans-disciplinary learning experiences, their attitudes toward marine and coastal environmental protection, and their capability of solving the problems related to marine and coastal environments. The researchers employed various methods to analyze the student reflection reports, student self-evaluation forms, and the tape-recorded class meetings. The findings suggest the following: the trans-disciplinary curriculum stands to be an innovative yet indispensable design for coastal management education; such a curriculum benefits students by equipping them with essential knowledge and skills to succeed in future marine conservation; action learning for marine and coastal sustainability serves as the final goal of trans-disciplinary learning project; a trans-disciplinary case study on the design of curricula provides effective knowledge integration of marine and coastal sustainability.

Sodium cyclamate is an effective artificial sweetner, which has been banned from the U.SD. market because of alleged carcinogenic properties. It appears that cyclohexylamine, liberated from cyclamate as a result of bacterial mtabolism, is the proximate carcinogen. In an effort to elucidate the extent to which analogues of cyclamate would enter into the bacterial metabolic pathway, as well as any stereochemical requirements which might exist, several 2-alkaly analogues of sodium cyclamate were prepared. It was found that trans-N-(2-methylcyclohexyl)sulfamate (trans-2a) and trans-N-(2-ethylcyclohexyl)sulfamate were hydrolyzed by freshly collected fecal suspensions from rats fed cyclamate, but not from control rats, at the same rate as cyclamate itself. trans-N-(2-Isopropylcyclohexyl)sulfamate (trans-2c) was not hydrolyzed at all. Surprisingly, two of the analogous cis compounds (cis-2a and cis-2c, respectively) were hydrolyzed by fecal suspensions from control, as well as from cyclamate-fed, rats. Moreover, cis-2a was hydrolyzed by incubating it in medium only. Thus, it is apparent that stereochemical influences on the chemical properties of these compounds are substantial. These results do not appear to point the way toward a safe, nonmetabolizable sweetening agent.

A new dopamine D2-like receptor ligand, (R,S)trans-5-hydroxy-2-[N-n0propyl-N-(3'-iodo-2'-propeny)amino]tet ralin ((R,S)trans-5-OH-PIPAT,3), based on high affinity dopamine receptor agonist 5-hydroxy-2-[N,N-(di-n-propyl)-2-amino]tetralin (5-OH-DPAT,1), was prepared. The synthesis was achieved by a reductive amination of 5-methoxy-2-tetralone with n-propylamine, followed by N-alkylation, to afford 5-methoxy-N-propyl-N-2'-aminotetralin,7. Reduction of 7 with tributyltin hydride gave the tri-n-butyl tin derivative,8, which was converted to 9 by an iododemetalation reaction. Demethylation of 9 gave the desired compound, (R,S)trans-5-OH-PIPAT,3. The resolved (R) and (S)trans-5-OH-PIPAT,3 were also quantitatively prepared. (author)

Hannah J. Edwards

2015-04-01

Full Text Available The selective synthesis of 2,6-trans-tetrahydropyran derivatives employing the rhodium catalysed addition of organoboron reagents to dihydropyranone templates, derived from a zinc-catalysed hetero-Diels-Alder reaction, is reported. The addition of both arylboronic acids and potassium alkenyltrifluoroborates have been accomplished in high yields using commercially-available [Rh(cod(OH]2 catalyst. The selective formation of the 2,6-trans-tetrahydropyran stereoisomer is consistent with a mechanism involving alkene association and carbometalation on the less hindered face of the dihydropyranone.

Protein trans-splicing of multiple atypical split inteins engineered from natural inteins.

Directory of Open Access Journals (Sweden)

Ying Lin

Full Text Available Protein trans-splicing by split inteins has many uses in protein production and research. Splicing proteins with synthetic peptides, which employs atypical split inteins, is particularly useful for site-specific protein modifications and labeling, because the synthetic peptide can be made to contain a variety of unnatural amino acids and chemical modifications. For this purpose, atypical split inteins need to be engineered to have a small N-intein or C-intein fragment that can be more easily included in a synthetic peptide that also contains a small extein to be trans-spliced onto target proteins. Here we have successfully engineered multiple atypical split inteins capable of protein trans-splicing, by modifying and testing more than a dozen natural inteins. These included both S1 split inteins having a very small (11-12 aa N-intein fragment and S11 split inteins having a very small (6 aa C-intein fragment. Four of the new S1 and S11 split inteins showed high efficiencies (85-100% of protein trans-splicing both in E. coli cells and in vitro. Under in vitro conditions, they exhibited reaction rate constants ranging from ~1.7 × 10(-4 s(-1 to ~3.8 × 10(-4 s(-1, which are comparable to or higher than those of previously reported atypical split inteins. These findings should facilitate a more general use of trans-splicing between proteins and synthetic peptides, by expanding the availability of different atypical split inteins. They also have implications on understanding the structure-function relationship of atypical split inteins, particularly in terms of intein fragment complementation.

Foods and beverages marketed in schools are typically of poor nutritional value. School districts may adopt policies and practices to restrict marketing of unhealthful foods and to promote healthful choices. Students' exposure to marketing practices differ by school demographics, but these differences have not yet been examined by district characteristics. We analyzed data from the 2012 School Health Policies and Practices Study to examine how food and beverage marketing and promotion policies and practices varied by district characteristics such as metropolitan status, size, and percentage of non-Hispanic white students. Most practices varied significantly by district size: a higher percentage of large districts than small or medium-sized districts restricted marketing of unhealthful foods and promoted healthful options. Compared with districts whose student populations were majority (>50%) non-Hispanic white, a higher percentage of districts whose student populations were minority non-Hispanic white (≤50% non-Hispanic white) prohibited advertising of soft drinks in school buildings and on school grounds, made school meal menus available to students, and provided families with information on school nutrition programs. Compared with suburban and rural districts, a higher percentage of urban districts prohibited the sale of soft drinks on school grounds and used several practices to promote healthful options. Preliminary findings showing significant associations between district demographics and marketing policies and practices can be used to help states direct resources, training, and technical assistance to address food and beverage marketing and promotion to districts most in need of improvement.

Full Text Available Los ácidos grasos con configuración trans poco se encuentran en los alimentos de manera natural, sino que se incorporan a éstos como consecuencia de modificaciones principalmente debidas a los procesos industriales de hidrogenación a que se someten los aceites para convertirlos en grasas sólidas. Aún cuando su estructura incluye dobles enlaces, el tipo de configuración permite un comportamiento biológico similar al de los ácidos grasos saturados, con efectos negativos sobre múltiples funciones celulares. La evidencia demuestra que son perjudiciales para la salud, en especial a lo que se refiere a riesgo de enfermedad cardiovascular, razón por la cual es importante disminuir su consumo. Teniendo en consideración la evidencia obtenida de investigaciones sobre las alteraciones del metabolismo producidas por los ácidos grasos trans, es posible plantear una precaución lógica hacia el consumo de dietas ricas en dichos ácidos. Sus efectos deletéreos serían incluso peores en aquellas poblaciones que consumen bajas cantidades de ácidos grasos esenciales. De ahí surge la importancia de iniciar con prontitud políticas sanitarias orientadas a controlar la aterosclerosis en nuestro país. Las mismas deben estar necesariamente sustentadas sobre un conocimiento profundo de las características o condiciones particulares a las que nuestra población se encuentra sometida.

Swedish research concerning the general health of trans people is scarce. Despite the diversity of the group, most Swedish research has focused on gender dysphoric people seeking medical help for their gender incongruence, or on outcomes after medical gender-confirming interventions. This paper examines self-rated health, self-reported disability and quality of life among a diverse group of trans people including trans feminine, trans masculine, and gender nonbinary people (identifying with a gender in between male of female, or identify with neither of these genders) as well as people self-identifying as transvestites. Participants were self-selected anonymously to a web-based survey conducted in 2014. Univariable and multivariable regression analyses were performed. Three backward selection regression models were conducted in order to identify significant variables for the outcomes self-rated health, self-reported disability and quality of life. Study participants included 796 individuals, between 15 and 94 years of age who live in Sweden. Respondents represented a heterogeneous group with regards to trans experience, with the majority being gender nonbinary (44 %), followed by trans masculine (24 %), trans feminine (19 %) and transvestites (14 %). A fifth of the respondents reported poor self-rated health, 53 % reported a disability and 44 % reported quality of life scores below the median cut-off value of 6 (out of 10). Nonbinary gender identity (adjusted Odds Ratio (aOR) = 2.19; 95 % CI: 1.24, 3.84), negative health care experiences (aOR = 1.92; 95 % CI: 1.26, 2.91) and not accessing legal gender recognition (aOR = 3.06; 95 % CI: 1.64, 5.72) were significant predictors for self-rated health.

Purpose: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous and persistent contaminants in aquatic bed sediments. A better understanding of their in-bed fate and transport is therefore key in minimising the risk to the environment over time through various remediation and monitoring strategies. Since ecological effects and risks are related to contaminant concentrations, this study developed CoReTranS, a predictive model that simulates one-dimensional organic contaminant reaction and transport in bed sediments. Materials and methods: CoReTranS was benchmarked against analytical solutions of simplified reactive transport models and validated using a published study of marsh sediments contaminated with petroleum-derived hydrocarbons from Wild Harbour, West Falmouth, MA, USA. Results and discussion: The CoReTranS model effectively predicted the vertical distribution of PAHs in the Wild Harbour sediments as confirmed by the modelling results from the published study. The CoReTranS model was also used to interpret results from a published study of PAH-contaminated fjord sediments from Kitimat Arm in British Columbia, Canada. Specific insights into the post-depositional fate and transport of selected PAHs in the Kitimat fjord sediments were obtained by comparing the measured concentration-depth profiles with the numerical results from the CoReTranS model. Key parameters such as effective diffusivity of contaminants and burial velocities of sediment particles were shown to possibly account for the predicted concentrations-depth profiles in the Kitimat fjord sediments. Conclusions: As demonstrated, CoReTranS can simulate reactive transport models in order to predict PAH concentration profiles in porewater under site-specific conditions. The information derived from the use of the CoReTranS model highlighted practical application of such information by engineers to site-specific risk assessment and remediation. (orig.)

The photocytotoxicity of a series of anticancer trans-dihydroxido [Pt(N(3))(2)(OH)(2)(NH(3))(X)] (X = alkyl or aryl amine) platinum(IV) diazido complexes has been examined, and the influence of cis-trans isomerism has been investigated. A series of photoactivatable Pt(IV)-azido complexes has been synthesized: The synthesis, characterization, and photocytotoxicity of six mixed-ligand ammine/amine Pt(IV) diazido complexes, cis,trans,cis-[Pt(N(3))(2)(OH)(2)(NH(3))(X)] where X = propylamine (4c), butylamine (5c), or pentylamine (6c) and aromatic complexes where X = pyridine (7c), 2-methylpyridine (8c), or 3-methylpyridine (9c) are reported. Six all-trans isomers have also been studied where X = methylamine (2t), ethylamine (3t), 2-methylpyridine (8t), 4-methylpyridine (10t), 3-methylpyridine (9t), and 2-bromo-3-methylpyridine (11t). All of the complexes exhibit intense azide-to-Pt(IV) LMCT bands (ca. 290 nm for trans and ca. 260 nm for cis). When irradiated with UVA light (365 nm), the Pt(IV) complexes undergo photoreduction to Pt(II) species, as monitored by UV-vis spectroscopy. The trans isomers of complexes containing aliphatic or aromatic amines were more photocytotoxic than their cis isomers. One of the cis complexes (9c) was nonphotocytotoxic despite undergoing photoreduction. Substitution of NH(3) ligands by MeNH(2) or EtNH(2) results in more potent photocytotoxicity for the all-trans complexes. The complexes were all nontoxic toward human keratinocytes (HaCaT) and A2780 human ovarian cancer cells in the dark, apart from the 3-methylpyridine (9t), 2-bromo-3-methylpyridine (11t), and 4-methylpyridine (10t) derivatives.

Gender identification and sex reassignment surgery in the trans population: a survey study in France.

Drawing from controversies between medical, legal, and associative actors about the obligation of sex reassignment surgeries (SRS) for people who intend to change their civil status, this article discusses the role that medical procedures, and particularly SRS, play in contemporary gender identifications and transition pathways in France. In 2010, the French National Institute of Health and Medical Research conducted a national survey in order to study the sociodemographic characteristics, access to medical, and psychological care, and state of health among trans individuals. After a long period of ethnographic work during which a partnership was established with trans actors to map the social, medical, and political landscape of trans communities, a questionnaire was developed and distributed between July and October 2010 in collaboration with most of the trans organizations and public and private health professionals operating in France. Overall, 381 self-identified trans individuals returned the anonymous self-administered questionnaire. The results highlighted the heterogeneity of the trans population, whose definition cannot be reduced to a group of individuals undergoing standardized hormonal treatments and SRS. Two central indicators, sex assigned at birth and gender self-identification, enabled us to describe and analyze different medical and legal pathways with a particular focus on SRS, which is often compulsory for a change of civil status in France. Although SRS remains an important factor in an individual's subjective evaluation of the success of the transition pathway, its practice varies depending on one's sex assigned at birth and gender identification.

Grape canes are a waste product from viticulture that show potential as an industrially extractable source of stilbenes, which are valuable for medical and other purposes. In this work, grape canes collected in three consecutive years (2014-2016) at six different places in South Moravia, Czech Republic were extracted, and the contents of trans -resveratrol, trans -ε-viniferin, and r2-viniferin were determined by high-performance liquid chromatography. The study included three blue grape varieties of Vitis vinifera L. (Cabernet Moravia, Blaufränkisch, and Piwi variety Laurot) and four white grape varieties (Chardonnay, Green Veltliner, Piwi variety Hibernal, and Piwi variety Malverina). From the viewpoint of producing extracts with high stilbenes content, the Hibernal variety is clearly the best. The mean amounts of the stilbenes for this variety at all localities and for all three years were 4.99 g/kg for trans -resveratrol, 3.24 g/kg for trans -ε-viniferin, and 1.73 g/kg for r2-viniferin. The influence of vintage, locality, and variety on the amounts of stilbenes was studied using PCA analysis. In contrast to expectations, there was no strong impact of locality on stilbenes content. The differences were varietal for most varieties, regardless of the area of cultivation. Laurot and Hibernal varieties did differ significantly in that respect, however, as they exhibited clear dependence on location.

Griffith, Richard

2015-03-01

Public trust and confidence in district nurses is essential to the nurse-patient relationship that underpins effective care and treatment. That trust and confidence has even greater focus for district nurses who care for patients in their own homes. Those patients need to be able to count on the professionalism and probity of their district nurses. The professionalism and probity of district nurses is based on their accountability, which protects the public by imposing standards on district nurses and holds them answerable for their acts and omissions. This is the first of a series of articles on accountability in district nursing practice to mark the introduction of the revised Nursing and Midwifery Code on the 31 March 2015. This month's article considers the key concepts of accountability.

Interim district energy implementation

Energy Technology Data Exchange (ETDEWEB)

Fearnley, R.; Susak, W. [City of Vancouver, BC (Canada); Johnstone, I. [BCG Services Inc., Vancouver, BC (Canada)

2001-07-01

The concept of district energy was introduced in the City of North Vancouver, a city of 45,000, in 1997. A preliminary study was completed in 1997, followed by a tour of some district energy facilities in Finland in the same year. In 1999 a large district energy study was completed by a consultant. The study indicated the need for an investment of $15 million to implement district heating in the City. Lack of sufficient financial resources and immediately connectable heat load, the project was considered a non-starter. Some of the other factors leading to shelving the project included no current significant pricing advantages over competing energy sources and no current opportunity for cogeneration, given the low price that BC Hydro is willing to pay for independently produced power. The project, although shelved for the moment, has not been discarded. Planning and exploration are continuing, aided by the City's commitment to energy efficiency and conservation, its long term planning horizon and its significant influence over the development of some prime real estate.

Energy supply and urban planning projects: Analysing tensions around district heating provision in a French eco-district

International Nuclear Information System (INIS)

Gabillet, Pauline

2015-01-01

Through the analysis of energy supply choices, this article explores the way in which energy priorities and their climate-related features are incorporated into urban public policy. These choices must take account of different factors, as is the case with district heating, which is justified as a vehicle of renewable energy while subject to pressure in eco-districts because its techno-economic balances are destabilised by falls in demand. Our study focuses particularly on the city of Metz (France), which has chosen district heating as the primary source for provision for the municipal area and for its first eco-district. We analyse the tensions within these choices, with particular attention to the way in which they are negotiated inside municipal departments and with the local energy operator. This enables us to explore the tensions in defining the scale that governs decisions and the linkages between energy-related and urban priorities. - Highlights: • Analyses of tensions in the choice of energy supplies for eco-districts. •District heating networks can be vehicles of renewable energy. • District heating networks are threatened by drops in energy consumption. • Energy supply issues oppose urban planning and energy policy in municipal departments. • Technical and financial adjustments can be made by the municipality to justify its energy choices

Le Bris, Karine; DeZeeuw, Jasmine; Godin, Paul J.; Strong, Kimberly

2017-12-01

Perfluorodecalin (PFD) is a molecule used in various medical applications for its capacity to dissolve gases. This potent greenhouse gas was detected for the first time in the atmosphere in 2005. We present infrared absorption cross-section spectra of a pure vapour of cis- and trans-perfluorodecalin at a resolution of 0.1 cm-1. Measurements were performed in the 560-3000 cm-1 spectral range using Fourier transform spectroscopy. The spectra have been compared with previous experimental data and theoretical calculations by density functional theory. The new experimental absorption cross-sections have been used to calculate a lifetime-corrected radiative efficiency at 300 K of 0.62 W m-2 ppb-1 and 0.57 W.m-2.ppb-1 for the cis and trans isomers respectively. This leads to a 100-year time horizon global warming potential of 8030 for cis-PFD and 7440 for trans-PFD.

RegTransBase describes a large number ofregulatory interactions reported in many organisms and contains varioustypes of experimental data, in particular: the activation or repressionof transcription by an identified direct regulator; determining thetranscriptional regulatory function of a protein (or RNA) directlybinding to DNA (RNA); mapping or prediction of binding site for aregulatory protein; characterization of regulatory mutations. Currently,the RegTransBase content is derived from about 3000 relevant articlesdescribing over 7000 experiments in relation to 128 microbes. It containsdata on the regulation of about 7500 genes and evidence for 6500interactions with 650 regulators. RegTransBase also contains manuallycreated position weight matrices (PWM) that can be used to identifycandidate regulatory sites in over 60 species.

Due to the ozone depletion potential and global warming potential of CFCs and HCFCs, CO 2 is considered as most potential alternative refrigerant. However, there are serious throttle losses and low system efficiency to CO 2 trans-critical cycle because of its low critical temperature and high operating pressure. The aim of this paper is to design an expander to recover expansion power in CO 2 trans-critical cycle. The theoretical analysis and calculation show that 14-23% of input power of compressor can be recovered. A prototype of rolling piston expander is designed and manufactured and its test facility is established. The test facility consists of CO 2 trans-critical cycle, the expander, the chilling water system and the cooling water system. The experimental results show that the recovery ratio and expander efficiency are affected by rotational speed, inlet temperature and mass flow of expander. The highest recovery ratio can reach to 0.145, which means 14.5% of input power of compressor can be recovered. The expander efficiency can reach to 45%.

The People Living with HIV StigmaSurvey UK 2015 was a community led national survey investigating experiences of people living with HIV in the UK in the past 12 months. Participants aged 18 and over were recruited through over 120 cross-sector community organisations and 46 HIV clinics to complete an anonymous online survey. Trans is an umbrella term which refers to individuals whose current gender identity is different to the gender they were assigned at birth. Trans participants self-identified via gender identity and gender at birth questions. Descriptive analyses of reported experiences in social and health care settings were conducted and multivariate logistic regression analyses were used to identify sociodemographic predictors of reporting being treated differently to non-HIV patients, and being delayed or refused healthcare treatment in the past 12 months. 31 out of 1576 participants (2%) identified as trans (19 trans women, 5 trans men, 2 gender queer/non-binary, 5 other). High levels of social stigma were reported for all participants, with trans participants significantly more likely to report worrying about verbal harassment (39% vs. 23%), and exclusion from family gatherings (23% vs. 9%) in the last 12 months, compared to cisgender participants. Furthermore, 10% of trans participants reported physical assault in the last 12 months, compared to 4% of cisgender participants. Identifying as trans was a predictor of reporting being treated differently to non-HIV patients (48% vs. 30%; aOR 2.61, CI 1.06, 6.42) and being delayed or refused healthcare (41% vs. 16%; aOR 4.58, CI 1.83, 11.44). Trans people living with HIV in the UK experience high levels of stigma and discrimination, including within healthcare settings, which is likely to impact upon health outcomes. Trans-specific education and awareness within healthcare settings could help to improve service provision for this demographic.

In recent years, newer technologies have been developed to reduce the trans-fat content of fats and oils used in manufacturing food products. To examine the implications of these changes on foods in the marketplace, a survey was conducted to assess current levels of trans and saturated fat in three food categories: margarines and butters; cookies and snack cakes; and savory snacks. A sampling of products from each category was conducted at a Wal-Mart Supercenter in the Minneapolis-St Paul, MN, metropolitan area in July of 2006. All information was obtained from product labels, except price, which was recorded from price listings on product shelving. Most margarines and butters (21 of 29), cookies and snack cakes (34 of 44), and savory snacks (31 of 40) were labeled as containing 0 g trans fat. However, some products contained substantial amounts of trans fat. Most notably, 3 of 40 savory snack products were labeled as containing > or =3 g trans fat. Significant inverse correlations were found between product price and the saturated and trans-fat content of margarines (r=-0.45) and savory snacks (r=-0.32). In conclusion, it appears that the food industry has made progress in reducing the trans-fat content in a variety of products. Nonetheless, consumers need to read product labels because the trans-fat content of individual products can vary considerably. Products that are lower in trans and saturated fat tend to cost more, which may be a barrier to their purchase for price-conscious consumers.

Overexpression of an isopentenyl diphosphate isomerase gene to enhance trans-polyisoprene production in Eucommia ulmoides Oliver

Directory of Open Access Journals (Sweden)

Chen Ren

2012-10-01

Full Text Available Abstract Background Natural rubber produced by plants, known as polyisoprene, is the most widely used isoprenoid polymer. Plant polyisoprenes can be classified into two types; cis-polyisoprene and trans-polyisoprene, depending on the type of polymerization of the isoprene unit. More than 2000 species of higher plants produce latex consisting of cis-polyisoprene. Hevea brasiliensis (rubber tree produces cis-polyisoprene, and is the key source of commercial rubber. In contrast, relatively few plant species produce trans-polyisoprene. Currently, trans-polyisoprene is mainly produced synthetically, and no plant species is used for its commercial production. Results To develop a plant-based system suitable for large-scale production of trans-polyisoprene, we selected a trans-polyisoprene-producing plant, Eucommia ulmoides Oliver, as the target for genetic transformation. A full-length cDNA (designated as EuIPI, Accession No. AB041629 encoding isopentenyl diphosphate isomerase (IPI was isolated from E. ulmoides. EuIPI consisted of 1028 bp with a 675-bp open reading frame encoding a protein with 224 amino acid residues. EuIPI shared high identity with other plant IPIs, and the recombinant protein expressed in Escherichia coli showed IPI enzymatic activity in vitro. EuIPI was introduced into E. ulmoides via Agrobacterium-mediated transformation. Transgenic lines of E. ulmoides overexpressing EuIPI showed increased EuIPI expression (up to 19-fold that of the wild-type and a 3- to 4-fold increase in the total content of trans-polyisoprenes, compared with the wild-type (non-transgenic root line control. Conclusions Increasing the expression level of EuIPI by overexpression increased accumulation of trans-polyisoprenes in transgenic E. ulmoides. IPI catalyzes the conversion of isopentenyl diphosphate to its highly electrophilic isomer, dimethylallyl diphosphate, which is the first step in the biosynthesis of all isoprenoids, including polyisoprene.

Previous research has reported high levels of non-suicidal self-injury (NSSI) in trans populations and younger age has been identified as a risk factor. To explore the prevalence of NSSI in a large group of young trans people and to identify risk factors for this group. Sociodemographic variables and measurements of NSSI (Self-Injury Questionnaire), psychopathology (Symptom Checklist-90-Revised), self-esteem (Rosenberg Self-Esteem Scale), victimization (Experiences of Transphobia Scale), interpersonal functioning (Inventory of Interpersonal Problems), and social support (Multidimensional Scale of Perceived Social Support). Two hundred sixty-eight young people attending a national gender clinic completed questionnaires assessing presence and frequency of NSSI and levels of general psychopathology, depression, anxiety, interpersonal problems, self-esteem, social support, transphobia, and information on hormone treatment. A lifetime presence of NSSI was identified in 46.3% of patients and 28.73% reported currently engaging in NSSI (within at least the past few months). Analyses showed that those with a lifetime presence of NSSI had significantly greater general psychopathology, lower self-esteem, had suffered more transphobia, and experienced greater interpersonal problems than those without NSSI. Findings were similar when comparing current with non-current NSSI. Overall, natal male patients reported less social support than natal female patients, but current NSSI was more common in natal female patients. Regression analyses confirmed that natal female gender and greater general psychopathology predicted current and lifetime NSSI. Further analyses confirmed that general psychopathology itself could be predicted by transphobic experiences, low self-esteem, and interpersonal problems, but not by the use of cross-sex hormones. These findings confirm that NSSI is common in trans youth and emphasize the need for interventions that decrease transphobia, increase social

trans -Resveratrol is often considered as one of the quality standards of red wine, and the development of a sensitive and reliable method for monitoring the trans -resveratrol levels in red wine is an urgent requirement for the quality control. Here, a novel voltammetric approach was described for probing trans -resveratrol using a graphene-modified glassy carbon (GC) electrode. The proposed electrode was prepared by one-step electrodeposition of reduced graphene oxide (ERGO) at a GC electrode. Compared with the bare GC electrode, the introduced graphene film on the electrode surface dramatically improved the sensitivity of the sensor response due to the π - π interaction between the graphene and trans -resveratrol. The developed sensor exhibited low detection limit of 0.2  μ M with wide linear range of 0.8-32  μ M and high stability. For the analysis of trans -resveratrol in red wine, the high anti-interference ability and the good recoveries indicated the great potential for practical applications.

District heating in Flensburg

Energy Technology Data Exchange (ETDEWEB)

Prinz, W.

1981-01-01

The majority of our population, but also of our authorities, are still skeptical or even disapproving towards district heating. The reasons of this negative attitude are partly psychological - e.g. the individualism of the Swiss and their dislike for too centralised structures and ''forced connections'' - but also the existence of finished gas supply networks and the fear of considerable pre-investments and torn streets over years. The following article - held as a speech on the information meeting ''District heating and the possible contribution of nuclear energy'' organised by the Swiss Association for Atomic Energy in Bern shows a practical problem solving at the example of the district heating in Flensburg and deals with these questions.

Effects of irradiation on trans fatty acids formation in ground beef

In order to give the consumer the assurance that meat processed by irradiation is a safe product, a great deal of research has been developed in the world. The effect of irradiation on the hygienic quality of meat and meat products is considered as related to the control of meat-borne parasites of humans; elimination of pathogens from fresh meat and poultry; and elimination of pathogens from processed meat. Lipid oxidation and associated changes are the major causes of the quality deterioration of meat during storage. Irradiation of lipids induces the production of free radicals, which react with oxygen, leading to the formation of carbonyls, responsible for alterations in food nutritional and sensorial characteristics. Trans fatty acids are present in ground beef and can also be formed during its processing. Interestingly, the trans fatty acids, due to their chemical and physical characteristics, show more resistance to the oxidizing process. This property motivated us to investigate the level of the trans fatty acids, as well as the level of oxidation in irradiated ground beef. Irradiation of ground beef was performed by gamma rays from a 60 Co source. The applied radiation doses were 0; 1.0; 2.0; 3.0; 4.0; 5.0; 6.0; 7.0 and 8.0 kGy. Lipid peroxidation in terms of TBA number and carbonyl content was monitored during storage. The sample characteristics and trans fatty acids composition were measured, following irradiation and after 60 and 90 days of storage at -10 deg. C

Shortage of energy increases profitability of district heating

International Nuclear Information System (INIS)

2003-01-01

Increased demand will cause the price of district heating to increase, but not to the level of the price of electricity. The cheapest heating alternative in Denmark, Norway and Sweden is district heating. In Norway, district heating is developed primarily for commercial buildings and housing cooperatives. Thirty per cent of all buildings under construction are prepared for district heating and the percentage will increase strongly in the coming time. The total net production of district heating in Norway in 2001 was 2000 GWh, which is only a small part of the total potential for district heating

The aim of the study was to examine the outcomes of transepithelial photorefractive keratectomy (Trans-PRK) and Femtosecond Laser-assisted in situ keratomileusis (Z-LASIK) for the correction of high myopia. A retrospective cohort study design was used. The study group included 792 eyes with high-grade myopia (- 6.0 diopters or higher) or high-grade myopia with astigmatism that were treated with Z-LASIK or Trans-PRK in 2013 through 2014 in an optical outpatient clinic of a large private medical service. The Trans-PRK group comprised of 674 eyes with a spherical equivalent (SE) of - 7.87 ± 1.46 and the Z-LASIK group comprised of 118 eyes with a SE of - 7.19 ± 0.81 (P PRK group was - 0.06 and - 0.02 in the Z-LASIK group (P = 0.545). Efficacy index values were 0.92 in the Trans-PRK group and 0.95 in the Z-LASIK group (P = 0.083), and corresponding safety index values were 0.95 and 0.97 (P = 0.056). An UCVA of 20/40 or better was achieved in 94.20% of eyes in the Trans-PRK group, and 98.31% in the Z-LASIK group (P = 0.063). The majority of eyes in both the Trans-PRK and Z-LASIK groups were within ± 0.5D of attempted correction: 59.35 and 64.71%, respectively (P = 0.271). Both Trans-PRK and Z-LASIK demonstrated excellent efficacy, safety and predictability profiles, with results comparable and in some cases superior to the current literature. Results of Z-LASIK were slightly better than those of Trans-PRK, though the preoperative SE of the latter was higher.

trans-Caryophyllene, a Natural Sesquiterpene, Causes Tracheal Smooth Muscle Relaxation through Blockade of Voltage-Dependent Ca2+ Channels

Full Text Available trans-Caryophyllene is a major component in the essential oils of various species of medicinal plants used in popular medicine in Brazil. It belongs to the chemical class of the sesquiterpenes and has been the subject of a number of studies. Here, we evaluated the effects of this compound in airway smooth muscle. The biological activities of trans-caryophyllene were examined in isolated bath organs to investigate the effect in basal tonus. Electromechanical and pharmacomechanical couplings were evaluated through the responses to K+ depolarization and exposure to acetylcholine (ACh, respectively. Isolated cells of rat tracheal smooth muscle were used to investigate trans-caryophyllene effects on voltage-dependent Ca2+ channels by using the whole-cell voltage-clamp configuration of the patch-clamp technique. trans-Caryophyllene showed more efficiency in the blockade of electromechanical excitation-contraction coupling while it has only minor inhibitory effect on pharmacomechanical coupling. Epithelium removal does not modify tracheal smooth muscle response elicited by trans-caryophyllene in the pharmacomechanical coupling. Under Ca2+-free conditions, pre-exposure to trans-caryophyllene did not reduce the contraction induced by ACh in isolated rat tracheal smooth muscle, regardless of the presence of intact epithelium. In the whole-cell configuration, trans-caryophyllene (3 mM, inhibited the inward Ba2+ current (IBa to approximately 50% of control levels. Altogether, our results demonstrate that trans-caryophyllene has anti-spasmodic activity on rat tracheal smooth muscle which could be explained, at least in part, by the voltage-dependent Ca2+ channels blockade.

Synthesis of cis - and trans-diisothiocyanato-bis(NHC) complexes of nickel(II) and applications in the Kumada-Corriu reaction

Metathetical reaction of AgSCN with a series of trans-dihalido-bis(carbene) nickel(II) complexes in CH3CN readily afforded the novel diisothiocyanato-bis(carbene) complexes [Ni(NCS)2(NHC)2] (trans-2a, NHC = 1,3-diisopropylbenzimidazolin-2-ylidene; trans-2b, NHC = 1,3-diisobutylbenzimidazolin-2-ylidene; trans-2c, NHC = 1,3- dibenzylbenzimidazolin-2-ylidene; cis-2d, NHC = 1,3-di(2-propenyl) benzimidazolin-2-ylidene; cis-2e, NHC = 1-propyl-3-methylbenzimidazolin-2- ylidene) as greenish-yellow powders in moderate to good yields. While dihalido-bis(carbene) Ni(II) complexes exclusively form trans-complexes, a trans-cis isomerization occurs upon halido-isothiocyanato exchange with complexes bearing less bulky carbene ligands, i.e., cis-2d/e. DFT calculations indicated that this isomerization can be attributed to a reduced energy difference between trans- and cis-isomers of diisothiocyanato complexes. All complexes have been characterized by multinuclear NMR spectroscopy, ESI mass spectrometry, and X-ray diffraction analysis. A catalytic study revealed that cis-complexes generally exhibit greater activities in the Kumada-Corriu coupling reaction. © 2010 American Chemical Society.

2016-12-01

Full Text Available This article posits a new taxonomy and framework for assessing regulatory coherence in the new generation of mega-regional, cross-cutting free trade agreements. Using the Trans-Pacific Partnership as the primary example, this article situates the rise of regulatory coherence within the current trade landscape, provides clear definitions of regulatory coherence, and argues that the real engine of regulatory coherence lies in the work of international standard setting organizations. This work has been little examined in the current literature. The article provides a detailed examination of the mechanics by which the Trans-Pacific Partnership promotes regulatory standardization and concludes with some normative implications and calls for future research.

Botswana has a shortage of health care workers, especially in primary healthcare. Retention and high performance of employees are closely linked to job satisfaction and motivation, which are both highest where employees' personal values and goals are realised. The aim of the study was to evaluate employees' personal values, and the current and desired organisational culture of the district health services as experienced by the primary health care workers. The study was conducted in the Ngamiland and Mahalapye health districts. This was a cross sectional survey. The participants were asked to select 10 values that best described their personal, current organisational and desired organisational values from a predetermined list. Sixty and 67 health care workers completed the survey in Mahalapye and Ngamiland districts, respectively. The top 10 prevalent organisational values experienced in both districts were: teamwork, patient satisfaction, blame, confusion, job insecurity, not sharing information and manipulation. When all the current values were assessed, 32% (Mahalapye) and 36% (Ngamiland) selected by health care workers were potentially limiting organisational effectiveness. The organisational values desired by health care workers in both districts were: transparency, professional growth, staff recognition, shared decision-making, accountability, productivity, leadership development and teamwork. The experience of the primary health care workers in the two health districts were overwhelmingly negative, which is likely to contribute to low levels of motivation, job satisfaction, productivity and high attrition rates. There is therefore urgent need for organisational transformation with a focus on staff experience and leadership development.

What made current Spanish feminism shift toward transfeminism? Based on in-depth interviews and literature reviews, we explore what factors facilitated the participation of trans* women in Spanish feminism. Tracing the history through relevant events such as the National Feminist Conferences, it becomes clear that trans* women participated in the 1993, 2000, and 2009 conferences, posing relevant issues regarding prostitution, transgenderism, and the political subject of feminism. Our research allows a break with global oppositional narratives, in which these movements are in conflict, and highlights the importance of understanding the vernacular nuances that take place in a particular geopolitical context.

2015-06-01

The re-engineering of primary healthcare (PHC) is regarded as an essential precursor to the implementation of National Health Insurance in South Africa, but improvements in the provision of PHC services have been patchy. The authors contend that the role of well- functioning rural district hospitals as a hub from which PHC services can be most efficiently managed has been underestimated, and that the management of district hospitals and PHC clinics need to be co-located at the level of the rural district hospital, to allow for proper integration of care and effective healthcare provision.

We report a comparative single-reference and multireference coupled-cluster investigation on the structure, potential energy surface, and IR spectroscopic properties of the trans peroxo nitrate radical, one of the key intermediates in stratospheric NOX chemistry. The previous single-reference ab initio studies predicted an unbound structure for the trans peroxo nitrate radical. However, our Fock space multireference coupled-cluster calculation confirms a bound structure for the trans peroxo nitrate radical, in accordance with the experimental results reported earlier. Further, the analysis of the potential energy surface in FSMRCC method indicates a well-behaved minima, contrary to the shallow minima predicted by the single-reference coupled-cluster method. The harmonic force field analysis, of various possible isomers of peroxo nitrate also reveals that only the trans structure leads to the experimentally observed IR peak at 1840 cm(-1). The present study highlights the critical importance of nondynamic correlation in predicting the structure and properties of high-energy stratospheric NOx radicals.

Para-muscular and trans-muscular approaches to the lumbar inter-vertebral foramen: an anatomical comparison.

2005-03-01

Foraminal and extra-foraminal disc herniations comprise up to 11.7% of all lumbar disc herniations. Facetectomy, which had been the classic approach, is now recognized as cause of pain and instability after surgery. Otherwise, posterior lateral approaches through a trans-muscular or a para-muscular technique offer no significant damage to key structures for spinal stability. The surgical anatomy of these approaches has already been described, but they were not compared. In order to quantify the angle of vision towards the intervertebral foramen offered by each technique, 12 fresh cadavers were dissected and studied regarding these approaches. The angle presented by trans-muscular approach was wider in all studied lumbar levels. Surgery through the trans-muscular approach is performed with a better working angle, requiring a smaller resection of surrounding tissues. Therefore, minor surgical trauma can be expected. Our measurements support previously published data that point the trans-muscular approach as the best surgical option.

The toluene-degrading strain Rhodococcus opacus PWD4 was found to hydroxylate d-limonene exclusively in the 6-position, yielding enantiomerically pure (+) trans-carveol and traces of (+) carvone. This biotransformation was studied using cells cultivated in chemostat culture with toluene as a carbon and energy source. The maximal specific activity of (+) trans-carveol formation was 14.7 U (g of cells [dry weight])−1, and the final yield was 94 to 97%. Toluene was found to be a strong competitive inhibitor of the d-limonene conversion. Glucose-grown cells did not form any trans-carveol from d-limonene. These results suggest that one of the enzymes involved in toluene degradation is responsible for this allylic monohydroxylation. Another toluene degrader (Rhodococcus globerulus PWD8) had a lower specific activity but was found to oxidize most of the formed trans-carveol to (+) carvone, allowing for the biocatalytic production of this flavor compound.

2004-01-01

Full Text Available The trans-European transport network has different effects at macro-regional, mezzo-regional and micro-regional level, and on urban systems development, and its effectiveness rises at the lower regional levels. Possible approaches to the trans-European transport network impact and effect survey and policy options have been pointed out. The importance of increased accessibility and mobility for regional expansion and for more balanced and polycentric system of city networks has been underlined. The question is how the new major transport infrastructure affects the development of functional complementarity between cities and regions. Changes of the spatial organization, utilization and structure of cities, as well as of social benefits and losses subsequent to impacts of trans-European transport corridor "X" on urban system Ćuprija-Jagodina-Paraćin at section Belgrade-Nis have been analysed. The new trans-European or major transport infrastructure does not per se create regional and urban system network development, although it can affect the conditions for the processes that create growth and development. The effects can be increased by co-ordination of measures of regional and urban policy, land use, transport and other policies. The guidances and options of urban systems and urban centres development policies in trans-European transport corridor, as well as possibilities to improve our planning system have been given. The necessary measure is the introduction of spatial impact assessment as sectorial policy instrument for the large transport infrastructure projects.

Full Text Available In the title compound, trans-[PtCl2(C7H9N2], the PtII atom is located on an inversion center and is coordinated by two 3,4-dimethylpyridine ligands and two chloride ligands, resulting in a typical slightly distorted square-planar geometry. The crystallographic inversion centre forces the value of the C—N—N—C torsion angle to be linear and the 3,4-dimethyl-pyridine ligands to be coplanar.

When Care and Concern Are Not Enough: School Personnel’s Development as Allies for Trans and Gender Non-Conforming Students

Directory of Open Access Journals (Sweden)

Robert A. Marx

2017-01-01

Full Text Available Trans people—and particularly trans youth—have come to the forefront of political and educational discussions, especially as legislation has aimed to ensure that school personnel act as enforcers of state-level policies targeting trans youth. For this reason, and because research demonstrates that youth in schools form attachments to and receive support from school personnel, our research looks at school personnel’s development as allies. By analyzing focus group data following a training workshop, we explore how participants understand their roles as allies to trans and gender non-conforming youth. We found that trans issues were salient and participants expressed new knowledge about and openness towards transgender youth, as well as care and concern for their wellbeing. Nonetheless, many participants retained frames of understanding that relied on trans people as Other and that situated their roles as allies through the frameworks of protection and care. We argue that these understandings of trans youth and the role of allies reinforces cisnormativity, and we push for a more nuanced understanding of allyship that moves beyond knowledge, beliefs, attitudes and intended behaviors as markers of allyship to ensure that allies do not reproduce cisnormativity even in their support of trans and gender non-conforming youth.

Full Text Available This work focuses on pollution control in the trans-boundary area of Taihu Basin. Considering the unique characteristics of the river network in the study area, a new methodology of pollution control is proposed aiming at improving the water quality in the trans-boundary area and reducing conflicts between up and downstream regions. Based on monitoring data and statistical analysis, important trans-boundary cross sections identified by the regional government were selected as important areas for consideration in developing management objectives; using a 1-D mathematicmodel and an effective weight evaluation model, the trans-boundary effective control scope (TECS of the study area was identified as the scope for pollutant control; the acceptable pollution load was then estimated using an established model targeting bi-directional flow. The results suggest that the water environmental capacity for chemical oxygen demand (COD, in order to guarantee reaching the target water quality standard in the TECS, is 160,806 t/year, and amounts to 16,098 t/year, 3493 t/year, and 39,768 t/year for ammonia nitrogen, total nitrogen, and total phosphorus, respectively. Our study method and results have been incorporated into the local government management project, and have been proven to be useful in designing a pollution control strategy and management policy.

Energy Assessment of Automated Mobility Districts

Energy Technology Data Exchange (ETDEWEB)

Chen, Yuche [National Renewable Energy Laboratory (NREL), Golden, CO (United States)

2017-08-03

Automated vehicles (AVs) are increasingly being discussed as the basis for on-demand mobility services, introducing a new paradigm in which a fleet of AVs displace private automobiles for day-to-day travel in dense activity districts. This project examines such a concept to displace privately owned automobiles within a region containing dense activity generators (jobs, retail, entertainment, etc.), referred to as an automated mobility district (AMDs). The project reviews several such districts including airport, college campuses, business parks, downtown urban cores, and military bases, with examples of previous attempts to meet the mobility needs apart from private automobiles, some with automated technology and others with more traditional transit based solutions. The issues and benefits of AMDs are framed within the perspective of intra-district, inter-district, and border issues, and the requirements for a modeling framework are identified to adequately reflect the breadth of mobility, energy, and emissions impact anticipated with AMDs.

Reaction of trans-[Ru(VI)(L)(O)(2)](2+) (1, L = 1,12-dimethyl-3,4:9,10-dibenzo-1,12-diaza-5,8-dioxacyclopentadecane, a tetradentate macrocyclic ligand with N(2)O(2) donor atoms) with nitrite in aqueous solution or in H(2)O/CH(3)CN produces the corresponding (nitrato)oxoruthenium(IV) species, trans-[Ru(IV)(L)(O)(ONO(2))](+) (2), which then undergoes relatively slow aquation to give trans-[Ru(IV)(L)(O)(OH(2))](2+). These processes have been monitored by both ESI/MS and UV/vis spectrophotometry. The structure of trans-[Ru(IV)(L)(O)(ONO(2))](+) (2) has been determined by X-ray crystallography. The ruthenium center adopts a distorted octahedral geometry with the oxo and the nitrato ligands trans to each other. The Ru=O distance is 1.735(3) A, the Ru-ONO(2) distance is 2.163(4) A, and the Ru-O-NO(2) angle is 138.46(35) degrees . Reaction of trans-[Ru(VI)(L)((18)O)(2)](2+) (1-(18)O(2)) with N(16)O(2)(-) in H(2)O/CH(3)CN produces the (18)O-enriched (nitrato)oxoruthenium(IV) species 2-(18)O(2). Analysis of the ESI/MS spectrum of 2-(18)O(2) suggests that scrambling of the (18)O atoms has occurred. A mechanism that involves linkage isomerization of the nitrato ligand and reversible oxygen atom transfer is proposed.

A good year for district heating

International Nuclear Information System (INIS)

Bakken, Stein Arne

2003-01-01

In Norway, high prices on electric power have caused economic progress for the district heating companies. The price of district heating is determined by the prices of power and fuel oil. However, the government wants to remove the tax on electricity to the industry, which is the district heating companies' major group of customers, along with public buildings. This is likely to entail a great loss of income

District heating in sequential energy supply

Persson, Urban; Werner, Sven

2012-01-01

Highlights: ► European excess heat recovery and utilisation by district heat distribution. ► Heat recovery in district heating systems – a structural energy efficiency measure. ► Introduction of new theoretical concepts to express excess heat recovery. ► Fourfold potential for excess heat utilisation in EU27 compared to current levels. ► Large scale excess heat recovery – a collaborative challenge for future Europe. -- Abstract: Increased recovery of excess heat from thermal power generation and industrial processes has great potential to reduce primary energy demands in EU27. In this study, current excess heat utilisation levels by means of district heat distribution are assessed and expressed by concepts such as recovery efficiency, heat recovery rate, and heat utilisation rate. For two chosen excess heat activities, current average EU27 heat recovery levels are compared to currently best Member State practices, whereby future potentials of European excess heat recovery and utilisation are estimated. The principle of sequential energy supply is elaborated to capture the conceptual idea of excess heat recovery in district heating systems as a structural and organisational energy efficiency measure. The general conditions discussed concerning expansion of heat recovery into district heating systems include infrastructure investments in district heating networks, collaboration agreements, maintained value chains, policy support, world market energy prices, allocation of synergy benefits, and local initiatives. The main conclusion from this study is that a future fourfold increase of current EU27 excess heat utilisation by means of district heat distribution to residential and service sectors is conceived as plausible if applying best Member State practice. This estimation is higher than the threefold increase with respect to direct feasible distribution costs estimated by the same authors in a previous study. Hence, no direct barriers appear with

Experiences of female partners of masculine-identifying trans persons.

Science.gov (United States)

Theron, Liesl; Collier, Kate L

2013-01-01

This paper explores the intimate relationship experiences of the cisgender (i.e., not transgender) female partners of masculine-identifying transgender persons, with a particular focus on these partners' self-understanding of their sexual orientation. Limited research about this topic has been conducted to date. Semi-structured interviews were conducted with eight South African women who are or have been cisgender female partners of masculine-identifying trans persons. Although the interviews showed that the relationship experiences of female partners of masculine-identifying trans persons are diverse, several common themes emerged in the narratives. The way that participants labelled their sexual orientation did not change from before to after their relationship with a transgender partner. The participants reported varied family and community responses to their relationships. Specific emotional and informational support needs for women with transgender partners were identified.

Identifying cis-mediators for trans-eQTLs across many human tissues using genomic mediation analysis.

Science.gov (United States)

Yang, Fan; Wang, Jiebiao; Pierce, Brandon L; Chen, Lin S

2017-11-01

The impact of inherited genetic variation on gene expression in humans is well-established. The majority of known expression quantitative trait loci (eQTLs) impact expression of local genes ( cis -eQTLs). More research is needed to identify effects of genetic variation on distant genes ( trans -eQTLs) and understand their biological mechanisms. One common trans -eQTLs mechanism is "mediation" by a local ( cis ) transcript. Thus, mediation analysis can be applied to genome-wide SNP and expression data in order to identify transcripts that are " cis -mediators" of trans -eQTLs, including those " cis -hubs" involved in regulation of many trans -genes. Identifying such mediators helps us understand regulatory networks and suggests biological mechanisms underlying trans -eQTLs, both of which are relevant for understanding susceptibility to complex diseases. The multitissue expression data from the Genotype-Tissue Expression (GTEx) program provides a unique opportunity to study cis -mediation across human tissue types. However, the presence of complex hidden confounding effects in biological systems can make mediation analyses challenging and prone to confounding bias, particularly when conducted among diverse samples. To address this problem, we propose a new method: Genomic Mediation analysis with Adaptive Confounding adjustment (GMAC). It enables the search of a very large pool of variables, and adaptively selects potential confounding variables for each mediation test. Analyses of simulated data and GTEx data demonstrate that the adaptive selection of confounders by GMAC improves the power and precision of mediation analysis. Application of GMAC to GTEx data provides new insights into the observed patterns of cis -hubs and trans -eQTL regulation across tissue types. © 2017 Yang et al.; Published by Cold Spring Harbor Laboratory Press.

TransCut: interactive rendering of translucent cutouts.

Li, Dongping; Sun, Xin; Ren, Zhong; Lin, Stephen; Tong, Yiying; Guo, Baining; Zhou, Kun

2013-03-01

We present TransCut, a technique for interactive rendering of translucent objects undergoing fracturing and cutting operations. As the object is fractured or cut open, the user can directly examine and intuitively understand the complex translucent interior, as well as edit material properties through painting on cross sections and recombining the broken pieces—all with immediate and realistic visual feedback. This new mode of interaction with translucent volumes is made possible with two technical contributions. The first is a novel solver for the diffusion equation (DE) over a tetrahedral mesh that produces high-quality results comparable to the state-of-art finite element method (FEM) of Arbree et al. but at substantially higher speeds. This accuracy and efficiency is obtained by computing the discrete divergences of the diffusion equation and constructing the DE matrix using analytic formulas derived for linear finite elements. The second contribution is a multiresolution algorithm to significantly accelerate our DE solver while adapting to the frequent changes in topological structure of dynamic objects. The entire multiresolution DE solver is highly parallel and easily implemented on the GPU. We believe TransCut provides a novel visual effect for heterogeneous translucent objects undergoing fracturing and cutting operations.

The aims of this study were to determine whether combining features of a western lifestyle in mice with trans fats in a high-fat diet, high-fructose corn syrup in the water, and interventions designed to promote sedentary behavior would cause the hepatic histopathological and metabolic abnormalities that characterize nonalcoholic steatohepatitis (NASH). Male C57BL/6 mice fed ad libitum high-fat chow containing trans fats (partially hydrogenated vegetable oil) and relevant amounts of a high-fructose corn syrup (HFCS) equivalent for 1-16 wk were compared with mice fed standard chow or mice with trans fats or HFCS omitted. Cage racks were removed from western diet mice to promote sedentary behavior. By 16 wk, trans fat-fed mice became obese and developed severe hepatic steatosis with associated necroinflammatory changes. Plasma alanine aminotransferase levels increased, as did liver TNF-alpha and procollagen mRNA, indicating an inflammatory and profibrogenic response to injury. Glucose intolerance and impaired fasting glucose developed within 2 and 4 wk, respectively. Plasma insulin, resistin, and leptin levels increased in a profile similar to that seen in patients with NASH. The individual components of this diet contributed to the phenotype independently; isocaloric replacement of trans fats with lard established that trans fats played a major role in promoting hepatic steatosis and injury, whereas inclusion of HFCS promoted food consumption, obesity, and impaired insulin sensitivity. Combining risk factors for the metabolic syndrome by feeding mice trans fats and HFCS induced histological features of NASH in the context of a metabolic profile similar to patients with this disease. Because dietary trans fats promoted liver steatosis and injury, their role in the epidemic of NASH needs further evaluation.

The situation of district heating, district cooling and energy supply in Hungary

International Nuclear Information System (INIS)

Sigmond, Gy.

2009-01-01

District heating represents with 650.000 heated dwellings approximately 15% of the Hungarian residential heating market. Since 1990 there is stagnation at the number of connected dwellings because erection of large settlements with prefab buildings has been stopped, and latter ones represent more than 75% of the dwelling heating market. During the same period, residential heat demand shrunk by 33%, because metering of hot water consumption resulted in changing consumer habits, and because of slowly but step by step refurbishment of buildings and heating systems. In Hungary district heating is present in all large and most of the medium size cities, in 92 cities together. Out of them, there is also a single village with a local district heating system, which heats more than 60% of cottages. The capacity os systems is spreading to a large extent. Approximately 36-36% of all heated dwellings are in Budapest and in 10 large cities in the country, while 148 of the total 202 systems have less than 10 MW capacities. In the fuel structure of district heating it is characteristic the overwhelming role of natural gas consumption, which has exceeded 80% already. Only a few numbers of heating power plants are fuelled by crown coal. The use of renewables is growing continuous, but, together with waste and waste energy, it amounts merely 8% of the total fuel use. Oil consumption is negligible. Currently the most promising DH-market is the service sector (public buildings and commercial consumers). DH-companies can sell their surplus supply capacities on the competitive market. Residential market can be preserved only with better legal conditions and with improving of demand side management. The industrial heat market can be gained when the erection of new power plants will be harmonized with industrial development in the frame of territorial planning. District cooling is just at the beginning in Hungary. Many new commercial and office buildings are erected with air conditioning

The Role of School District Science Coordinators in the District-Wide Appropriation of an Online Resource Discovery and Sharing Tool for Teachers

Lee, Victor R.; Leary, Heather M.; Sellers, Linda; Recker, Mimi

2014-06-01

When introducing and implementing a new technology for science teachers within a school district, we must consider not only the end users but also the roles and influence district personnel have on the eventual appropriation of that technology. School districts are, by their nature, complex systems with multiple individuals at different levels in the organization who are involved in supporting and providing instruction. Varying levels of support for new technologies between district coordinators and teachers can sometimes lead to counterintuitive outcomes. In this article, we examine the role of the district science coordinator in five school districts that participated in the implementation of an online resource discovery and sharing tool for Earth science teachers. Using a qualitative approach, we conducted and coded interviews with district coordinators and teachers to examine the varied responsibilities associated with the district coordinator and to infer the relationships that were developed and perceived by teachers. We then examine and discuss two cases that illustrate how those relationships could have influenced how the tool was adopted and used to differing degrees in the two districts. Specifically, the district that had high support for online resource use from its coordinator appeared to have the lowest level of tool use, and the district with much less visible support from its coordinator had the highest level of tool use. We explain this difference in terms of how the coordinator's promotion of teacher autonomy took distinctly different forms at those two districts.

Full Text Available This essay seeks to make an examination on how the gender category influences in the development process, based on the concept of development as freedom by Amartya Sen. In view of this purpose, we analyze the main human rights violations suffered by travesties and transsexuals due to the female and male identity construction in contrast to social norms establishing hierarchical positions of men and women as constituents of male and female categories. In other words, conflicts made in the wake of gender relations. This study is the result of a literature review and analysis of data on homophobic violence against trans experience.

Understanding the organisational culture of district health services: Mahalapye and Ngamiland health districts of Botswana

Directory of Open Access Journals (Sweden)

2015-11-01

Full Text Available Background: Botswana has a shortage of health care workers, especially in primary healthcare. Retention and high performance of employees are closely linked to job satisfaction and motivation, which are both highest where employees’ personal values and goals are realised. Aim: The aim of the study was to evaluate employees’ personal values, and the current and desired organisational culture of the district health services as experienced by the primary health care workers. Setting: The study was conducted in the Ngamiland and Mahalapye health districts. Method: This was a cross sectional survey. The participants were asked to select 10 values that best described their personal, current organisational and desired organisational values from a predetermined list. Results: Sixty and 67 health care workers completed the survey in Mahalapye and Ngamiland districts, respectively. The top 10 prevalent organisational values experienced in both districts were: teamwork, patient satisfaction, blame, confusion, job insecurity, not sharing information and manipulation. When all the current values were assessed, 32% (Mahalapye and 36% (Ngamiland selected by health care workers were potentially limiting organisational effectiveness. The organisational values desired by health care workers in both districts were: transparency, professional growth, staff recognition, shared decision-making, accountability, productivity, leadership development and teamwork. Conclusions: The experience of the primary health care workers in the two health districts were overwhelmingly negative, which is likely to contribute to low levels of motivation, job satisfaction, productivity and high attrition rates. There is therefore urgent need for organisational transformation with a focus on staff experience and leadership development.

Exploring the ethos of district nursing, 1885-1985.

Science.gov (United States)

Madsen, Wendy

2013-06-01

The history of district nursing in Australia explored in this paper reveals a continuity in the essential values held by district nurses for over a century. These nurses practised holistic, family-centred nursing from the very origins of district nursing service. The events surrounding the establishment of Community Health Centres in the 1970s challenged district nurses to reconsider their role, while at the same time reconfirming their essential ethos. These values that underpinned district nursing practice and challenges to these values are examined in this paper.

Computer code TRANS-ACE predicting for fire and explosion accidents in nuclear fuel reprocessing plants

International Nuclear Information System (INIS)

Abe, Hitoshi; Nishio; Gunji; Naito, Yoshitaka

1993-11-01

The accident analysis code TRANS-ACE was developed to evaluate the safety of a ventilation system in a reprocessing plant in the event of fire and explosion accidents. TRANS-ACE can evaluate not only the integrity of a ventilation system containing HEPA filters but also the source term of radioactive materials for release out of a plant. It calculates the temperature, pressure, flow rate, transport of combustion materials and confinement of radioactive materials in the network of a ventilation system that might experience a fire or explosion accident. TRANS-ACE is based on the one-dimensional compressible thermo-fluid analysis code EVENT developed by Los Alamos National Laboratory (LANL). Calculational functions are added for the radioactive source term, heat transfer and radiation to cell and duct walls and HEPA filter integrity. For the second edition in the report, TRANS-ACE has been improved incorporating functions for the initial steady-state calculation to determine the flow rates, pressure drops and temperature in the network before an accident mode analysis. It is also improved to include flow resistance calculations of the filters and blowers in the network and to have an easy to use code by simplifying the input formats. This report is to prepare an explanation of the mathematical model for TRANS-ACE code and to be the user's manual. (author)

Coastal livelihood transitions under globalization with implications for trans-ecosystem interactions.

Kramer, Daniel B; Stevens, Kara; Williams, Nicholas E; Sistla, Seeta A; Roddy, Adam B; Urquhart, Gerald R

2017-01-01

Anthropogenic threats to natural systems can be exacerbated due to connectivity between marine, freshwater, and terrestrial ecosystems, complicating the already daunting task of governance across the land-sea interface. Globalization, including new access to markets, can change social-ecological, land-sea linkages via livelihood responses and adaptations by local people. As a first step in understanding these trans-ecosystem effects, we examined exit and entry decisions of artisanal fishers and smallholder farmers on the rapidly globalizing Caribbean coast of Nicaragua. We found that exit and entry decisions demonstrated clear temporal and spatial patterns and that these decisions differed by livelihood. In addition to household characteristics, livelihood exit and entry decisions were strongly affected by new access to regional and global markets. The natural resource implications of these livelihood decisions are potentially profound as they provide novel linkages and spatially-explicit feedbacks between terrestrial and marine ecosystems. Our findings support the need for more scientific inquiry in understanding trans-ecosystem tradeoffs due to linked-livelihood transitions as well as the need for a trans-ecosystem approach to natural resource management and development policy in rapidly changing coastal regions.

Trans individuals' facilitative coping: An analysis of internal and external processes.

Budge, Stephanie L; Chin, Mun Yuk; Minero, Laura P

2017-01-01

Existing research on trans individuals has primarily focused on their negative experiences and has disproportionately examined coming-out processes and identity development stages. Using a grounded theory approach, this qualitative study sought to examine facilitative coping processes among trans-identified individuals. Facilitative coping was operationalized as processes whereby individuals seek social support, learn new skills, change behaviors to positively adapt, and find alternative means to seek personal growth and acceptance. The sample included 15 participants who self-identified with a gender identity that was different from their assigned sex at birth. Results yielded a total of nine overarching themes: Accepting Support from Others, Actions to Increase Protection, Active Engagement Throughout the Transition Process, Actively Seeking Social Interactions, Engaging in Exploration, Internal Processes Leading to Self-Acceptance, Self-Efficacy, Shifts Leading to Embracing Change and Flexibility, and Utilization of Agency. Based on the analysis, a theoretical model emerged that highlighted the importance of internal and external coping processes in facilitating gender identity development and navigating stressors among trans individuals. Clinical implications focusing on how to implement facilitative coping processes are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Coastal livelihood transitions under globalization with implications for trans-ecosystem interactions.

Directory of Open Access Journals (Sweden)

Daniel B Kramer

Full Text Available Anthropogenic threats to natural systems can be exacerbated due to connectivity between marine, freshwater, and terrestrial ecosystems, complicating the already daunting task of governance across the land-sea interface. Globalization, including new access to markets, can change social-ecological, land-sea linkages via livelihood responses and adaptations by local people. As a first step in understanding these trans-ecosystem effects, we examined exit and entry decisions of artisanal fishers and smallholder farmers on the rapidly globalizing Caribbean coast of Nicaragua. We found that exit and entry decisions demonstrated clear temporal and spatial patterns and that these decisions differed by livelihood. In addition to household characteristics, livelihood exit and entry decisions were strongly affected by new access to regional and global markets. The natural resource implications of these livelihood decisions are potentially profound as they provide novel linkages and spatially-explicit feedbacks between terrestrial and marine ecosystems. Our findings support the need for more scientific inquiry in understanding trans-ecosystem tradeoffs due to linked-livelihood transitions as well as the need for a trans-ecosystem approach to natural resource management and development policy in rapidly changing coastal regions.

Trans-dimensional matched-field geoacoustic inversion with hierarchical error models and interacting Markov chains.

Science.gov (United States)

Dettmer, Jan; Dosso, Stan E

2012-10-01

This paper develops a trans-dimensional approach to matched-field geoacoustic inversion, including interacting Markov chains to improve efficiency and an autoregressive model to account for correlated errors. The trans-dimensional approach and hierarchical seabed model allows inversion without assuming any particular parametrization by relaxing model specification to a range of plausible seabed models (e.g., in this case, the number of sediment layers is an unknown parameter). Data errors are addressed by sampling statistical error-distribution parameters, including correlated errors (covariance), by applying a hierarchical autoregressive error model. The well-known difficulty of low acceptance rates for trans-dimensional jumps is addressed with interacting Markov chains, resulting in a substantial increase in efficiency. The trans-dimensional seabed model and the hierarchical error model relax the degree of prior assumptions required in the inversion, resulting in substantially improved (more realistic) uncertainty estimates and a more automated algorithm. In particular, the approach gives seabed parameter uncertainty estimates that account for uncertainty due to prior model choice (layering and data error statistics). The approach is applied to data measured on a vertical array in the Mediterranean Sea.

Trans-European transport networks influence on the regional development and urban systems: Serbian experience

Directory of Open Access Journals (Sweden)

Maksin-Mićić Marija

2004-01-01

Full Text Available The trans-European transport network has different effects at macro regional mezzo-regional and micro-regional level, and its effectiveness rises with the lower regional levels. Possible approaches to the trans-European transport network impact and effect survey and policy options have been pointed out. The importance of increased accessibility and mobility for regional expansion and for a more balanced and polycentric system of city networks has been underlined. Changes in the spatial organization utilization and structure of cities, as well as in social benefits and losses subsequent to impacts of trans-European transport corridor "X" section Belgrade-Niš have been analyzed. The new trans-European or major transport infrastructure does not per se create regional and urban system network development, although it can affect the conditions for the processes that create growth and development. The effects can be increased by co-ordination of measures of regional, spatial and urban policy, land use transport, environmental and other policies. The necessary measure is the introduction of spatial impact assessment as sartorial policy instrument for the large transport infrastructure plans and projects.

Grapevine-shoot extract Vineatrol30 contains abundant resveratrol monomers and oligomers with health-promoting potential. However, the oral bioavailability of these compounds in humans is low (˂1-2%). The aim of this study was to improve the oral bioavailability of resveratrol from vineatrol by micellar solubilization. Twelve healthy volunteers (six women, six men) randomly ingested a single dose of 500 mg vineatrol (30 mg trans-resveratrol, 75 mg trans-ε-viniferin) as native powder or liquid micelles. Plasma and urine were collected at baseline and over 24 h after intake. Resveratrol and viniferin were analyzed by HPLC. The area under the plasma concentration-time curve (AUC) and mean maximum plasma trans-resveratrol concentrations were 5.0-fold and 10.6-fold higher, respectively, after micellar supplementation relative to the native powder. However, no detectable amounts of trans-ε-viniferin were found in either plasma or urine. The transepithelial permeability of trans-resveratrol and trans-ε-viniferin across differentiated Caco-2 monolayers was consistent to the absorbed fractions in vivo. The oral bioavailability of trans-resveratrol from the grapevine-shoot extract Vineatrol30 was significantly increased using a liquid micellar formulation, without any treatment-related adverse effects, making it a suitable system for improved supplementation of trans-resveratrol. © 2018 WILEY-VCH Verlag GmbH & Co.

2014-07-01

Full Text Available Trans fatty acids are considered to be the important modifiable factor of the ovulatory infertility disorder. The purpose of this study was to test the hypothesis that higher trans fatty acids of erythrocytes (RBC are associated with the risk of ovulatory infertility disorder in polycystic ovarian syndrome (PCOS. Thirty five infertile women with polycystic ovarian syndrome, defined by AES criteria and 29 age-matched healthy women as a control group were recruited for the study. After physical measurements and nutritional assessment, blood samples were collected. Fasting serum glucose and insulin were measured, and then insulin resistance was calculated by homeostasis model assessment (HOMA-IR. Erythrocyte fatty acids were measured by gas chromatography. The patients group had higher waist circumference (WC, insulin levels, HOMA-IR than controls (p< 0.05. Also, case group had lower percentage of normal BMI (BMI<25, physical activity and education levels than healthy women (p< 0.05. Among RBC trans fatty acids only trans linoleate (18:2t were significantly higher in case group than control women (p= 0.019. PCOS group tended to consume more food rich in TFAs than the control group. Logistic regression analysis also showed that only 18:2t is positively associated with risk of ovulatory disorder infertility in PCOS (OR= 1.225, 95% CI. 1.024-1.465; P= 0.026, which was not affected after adjustment for BMI, physical activity and education levels. The results suggested that RBC trans fatty acids might be a predictor of increased risk for ovulatory infertility disorder in women with PCOS.

About the marshallian industrial district and the theory of the contemporary district. A brief critical reconstruction

Directory of Open Access Journals (Sweden)

Giacomo Becattini

2002-01-01

Full Text Available As a departing point, the paper presents the historical genesis of the concept of industrial district focusing on the scientific views of the pioneer of this field, Alfred Marshall. The concept has its origins in the observation of the current industrial reality, mainly of the British one. The purpose is to give an explanation to the difficulties of the classic theory and to study the challenges of the class conflicts. The economic conditions which launched British industrial districts were present, grosso modo, in Italy after the second World War. Some contributions have dealt with the little industrialisation of some Italian regions and using Marshallian thoughts have rediscovered the industrial districts phenomenon. This is the starting point of a high number of scientific contribution in Italy and abroad. Some of these international studies, particularly the ones made by Spanish experts, are quoted. The text analyses the link between districts-made in Italy with the competitive advantages of Italian products in many economic activities (i.e. clothing, shoes, furniture, etc.. Finally, in the third part the paper reviews some new contributions on the industrial district in Italy.

Decentralization in Zambia: resource allocation and district performance.

Science.gov (United States)

Bossert, Thomas; Chitah, Mukosha Bona; Bowser, Diana

2003-12-01

Zambia implemented an ambitious process of health sector decentralization in the mid 1990s. This article presents an assessment of the degree of decentralization, called 'decision space', that was allowed to districts in Zambia, and an analysis of data on districts available at the national level to assess allocation choices made by local authorities and some indicators of the performance of the health systems under decentralization. The Zambian officials in health districts had a moderate range of choice over expenditures, user fees, contracting, targeting and governance. Their choices were quite limited over salaries and allowances and they did not have control over additional major sources of revenue, like local taxes. The study found that the formula for allocation of government funding which was based on population size and hospital beds resulted in relatively equal per capita expenditures among districts. Decentralization allowed the districts to make decisions on internal allocation of resources and on user fee levels and expenditures. General guidelines for the allocation of resources established a maximum and minimum percentage to be allocated to district offices, hospitals, health centres and communities. Districts tended to exceed the maximum for district offices, but the large urban districts and those without public district hospitals were not even reaching the minimum for hospital allocations. Wealthier and urban districts were more successful in raising revenue through user fees, although the proportion of total expenditures that came from user fees was low. An analysis of available indicators of performance, such as the utilization of health services, immunization coverage and family planning activities, found little variation during the period 1995-98 except for a decline in immunization coverage, which may have also been affected by changes in donor funding. These findings suggest that decentralization may not have had either a positive or

Paternally expressed Peg3 controls maternally expressed Zim1 as a trans factor.

Directory of Open Access Journals (Sweden)

An Ye

Full Text Available The expression of two adjacent imprinted genes, Peg3 and Zim1, is inversely correlated: down-regulation of Peg3 coinciding with up-regulation of Zim1. The current study characterized this inverse correlation using a mutant allele targeting Peg3. According to the results, the mutation on the paternal allele of Peg3 resulted in a dramatic increase in the transcription levels of the maternal allele of Zim1, suggesting the involvement of unknown trans factors in this trans-allelic event. Subsequent ChIP experiments revealed that the protein encoded by Peg3 itself binds to the zinc finger exon of Zim1, which is modified with the repression mark H3K9me3. Interestingly, the levels of H3K9me3 on Zim1 are also reduced in the mutant cells lacking the protein PEG3, suggesting potential roles for PEG3 in establishing H3K9me3 on Zim1. Reintroducing PEG3 into the mutant cell restored down-regulation of Zim1, confirming the predicted repressor role for Peg3 on Zim1. Overall, these results demonstrated that paternally expressed Peg3 controls maternally expressed Zim1 as a trans factor. The current study also provides the first case for the trans-allelic interaction of two oppositely imprinted genes through their gene products.

Pituitary masses are common lesions accounting for about 15-20% of all brain tumours. Oozing blood is an annoyance in microscopic sublabial trans-sphenoidal approach for these masses. There have been many ways of reducing the ooze, having their own pros and cons. To find out the efficacy and safety of clonidine in reducing blood loss in pituitary adenoma surgery through a randomized masked trial. It was a prospective randomized controlled trial done. Total 50 patients of pituitary adenomas were randomized into two groups. Group A (25 patients) was given 200 μg clonidine orally, while Group B (25 patients) was given placebo. Surgeon, anaesthesiologist and patient were blinded for the trial. Sublabial trans-septal trans-sphenoidal approach to sella and excision of mass was performed in each patient. Patients were studied for pre-, intra- and post-operative blood pressure and heart rate, pre- and post-operative imaging findings, intra-operative blood loss, bleeding grading by surgeon, surgeon's satisfaction about condition of specific part and quality of surgical field, operative time and extent of resection. Blood loss during the surgery, operative time and bleeding grading by the surgeon were found significantly less in the clonidine group, while quality of surgical field, condition of the specific part and extent of resection were found significantly better in the clonidine group (p value trans-sphenoidal microscopic pituitary adenoma surgeries.

2018-01-01

Abstract High-throughput transcriptome sequencing (RNAseq) is the universally applied method for target-free transcript identification and gene expression quantification, generating huge amounts of data. The constraint of accessing such data and interpreting results can be a major impediment in postulating suitable hypothesis, thus an innovative storage solution that addresses these limitations, such as hard disk storage requirements, efficiency and reproducibility are paramount. By offering a uniform data storage and retrieval mechanism, various data can be compared and easily investigated. We present a sophisticated system, TransAtlasDB, which incorporates a hybrid architecture of both relational and NoSQL databases for fast and efficient data storage, processing and querying of large datasets from transcript expression analysis with corresponding metadata, as well as gene-associated variants (such as SNPs) and their predicted gene effects. TransAtlasDB provides the data model of accurate storage of the large amount of data derived from RNAseq analysis and also methods of interacting with the database, either via the command-line data management workflows, written in Perl, with useful functionalities that simplifies the complexity of data storage and possibly manipulation of the massive amounts of data generated from RNAseq analysis or through the web interface. The database application is currently modeled to handle analyses data from agricultural species, and will be expanded to include more species groups. Overall TransAtlasDB aims to serve as an accessible repository for the large complex results data files derived from RNAseq gene expression profiling and variant analysis.

Permethrin, a pyrethroid insecticide, is suspected to induce neuronal and hormonal disturbances in humans. The widespread exposure of the populations has been confirmed by the detection of the urinary metabolites of permethrin in biomonitoring studies. Permethrin is a chiral molecule presenting two forms, the cis and the trans isomers. Because in vitro studies indicated a metabolic interaction between the trans and cis isomers of permethrin, we adapted and calibrated a PBPK model for trans- and cis-permethrin separately in rats. The model also describes the toxicokinetics of three urinary metabolites, cis- and trans-3-(2,2 dichlorovinyl)-2,2-dimethyl-(1-cyclopropane) carboxylic acid (cis- and trans-DCCA), 3-phenoxybenzoic acid (3-PBA) and 4′OH-phenoxybenzoic acid (4′-OH-PBA). In vivo experiments performed in Sprague–Dawley rats were used to calibrate the PBPK model in a Bayesian framework. The model captured well the toxicokinetics of permethrin isomers and their metabolites including the rapid absorption, the accumulation in fat, the extensive metabolism of the parent compounds, and the rapid elimination of metabolites in urine. Average hepatic clearances in rats were estimated to be 2.4 and 5.7 L/h/kg for cis- and trans-permethrin, respectively. High concentrations of the metabolite 4′-OH-PBA were measured in urine compared to cis- and trans-DCCA and 3-PBA. The confidence in the extended PBPK model was then confirmed by good predictions of published experimental data obtained using the isomers mixture. The extended PBPK model could be extrapolated to humans to predict the internal dose of exposure to permethrin from biomonitoring data in urine. - Highlights: • A PBPK model of isomers of permethrin and its urinary metabolites was developed. • A quantitative link was established for permethrin and its biomarkers of exposure. • The bayesian framework allows getting confidence interval on the estimated parameters. • The PBPK model can be extrapolated

Introduction: [{sup 18}F]Mefway is a serotonin 5-HT{sub 1A} PET radiotracer with high specificity and favorable in vivo imaging properties. The chemical structure of [{sup 18}F]mefway permits {sup 18}F labeling in either the cis or trans positions at the 4-cyclohexyl site. We have previously reported on the in vivo kinetics of trans-[{sup 18}F]mefway in the nonhuman primate. In this work, we compare the in vivo binding of cis-[{sup 18}F]mefway and trans-[{sup 18}F]mefway to evaluate the properties of cis-[{sup 18}F]mefway for 5-HT{sub 1A} PET imaging. Methods: The cis- and trans-[{sup 18}F]mefway tracers were synthesized via nucleophilic substitution with their respective tosyl precursors. Two monkeys (one male, one female) were given bolus injections of both cis- and trans-labeled [{sup 18}F]mefway in separate experiments. Dynamic scans were acquired for 90 min with a microPET P4 scanner. Time-activity curves were extracted in the areas of the mesial temporal cortex (MTC), anterior cingulate gyrus (aCG), insular cortex (IC), raphe nuclei (RN) and cerebellum (CB). The in vivo behavior of the radiotracers was compared based upon the nondisplaceable binding potential (BP{sub ND}) using the CB as a reference region. Results: Averaged over the two subjects, BP{sub ND} values were as follows: MTC: 7.7, 0.58; aCG: 4.95, 0.32; IC: 3.27, 0.2; and RN: 3.05, 0.13, for trans-[{sup 18}F]mefway and cis-[{sup 18}F]mefway, respectively. Conclusion: The cis-labeled [{sup 18}F]mefway tracer has low specific binding throughout the 5-HT{sub 1A} regions of the brain compared to trans-[{sup 18}F]mefway, suggesting that the target-to-background binding of cis-[{sup 18}F]mefway may limit its use for in vivo assessment of 5-HT{sub 1A} binding.

Full Text Available The color expression of anthocyanins can be affected by a variety of environmental factors and structural characteristics. Anthocyanin acylation (type and number of acids is known to be key, but the influence of acyl isomers (with unique stereochemistries remains to be explored. The objective of this study was to investigate the effects of cis–trans configuration of the acylating group on the spectral and colorimetric properties of anthocyanins. Petunidin-3-rutinoside-5-glucoside (Pt-3-rut-5-glu and Delphinidin-3-rutinoside-5-glucoside (Dp-3-rut-5-glu and their cis and trans coumaroylated derivatives were isolated from black goji and eggplant, diluted in pH 1–9 buffers, and analyzed spectrophotometrically (380–700 nm and colorimetrically (CIELAB during 72 h of storage (25 °C, dark. The stereochemistry of the acylating group strongly impacted the spectra, color, and stability of the Dp and Pt anthocyanins. Cis acylated pigments exhibited the greatest λmax in all pH, as much as 66 nm greater than their trans counterparts, showing bluer hues. Cis acylation seemed to reduce hydration across pH, increasing color intensity, while trans acylation generally improved color retention over time. Dp-3-cis-p-cou-rut-5-glu exhibited blue hues even in pH 5 (C*ab = 10, hab = 256° where anthocyanins are typically colorless. Cis or trans double bond configurations of the acylating group affected anthocyanin spectral and stability properties.

The stable conformers of trans-2-methoxycinnamic acid (trans-2MCA) are determined by potential energy profile analysis. The energies of the s-cis and s-trans conformers of trans-2MCA determined by B3LYP/cc-pVTZ method are -612.9788331 Hartrees and -612.9780953 Hartrees, respectively. The vibrational and electronic investigations of the stable s-cis and s-trans conformers of trans-2-methoxycinnamic acid have been carried out extensively with FTIR and FT-Raman spectral techniques. The s-cis conformer (I) with a (C16-C17-C18-O19) dihedral angle equal to 0° is found to be more favoured relative to the one s-trans (II) with (C16-C17-C18-O19) = 180°, possibly due to delocalization, hydrogen bonding and steric repulsion effects between the methoxy and acrylic acid groups. The DFT studies are performed with B3LYP method by utilizing 6-311++G** and cc-pVTZ basis sets to determine the structure, thermodynamic properties, vibrational characteristics and chemical shifts of the compound. The total dipole moments of the conformers determined by B3LYP/cc-pVTZ method are 3.35 D and 4.87 D for s-cis and s-trans, respectively. It reveals the higher polarity of s-trans conformer of trans-2MCA molecule. The electronic and steric influence of the methoxy group on the skeletal frequencies has been analysed. The energies of the frontier molecular orbitals and the LUMO-HOMO energy gap have been determined. The MEP of s-cis conformer lie in the range +1.374e × 10-2 to -1.374e × 10-2 while for s-trans it is +1.591e × 10-2 to -1.591e × 10-2. The total electron density of s-cis conformer lie in the range +5.273e × 10-2 to -5.273e × 10-2 while for s-trans it is +5.403e × 10-2 to -5.403e × 10-2. The MEP and total electron density shows that the s-cis conformer is less polar, less reactive and more stable than the s-trans conformer. All the reactivity descriptors of the molecule have been discussed. Intramolecular electronic interactions and their stabilisation energies have analysed

RevTrans: multiple alignment of coding DNA from aligned amino acid sequences

DEFF Research Database (Denmark)

Wernersson, Rasmus; Pedersen, Anders Gorm

2003-01-01

The simple fact that proteins are built from 20 amino acids while DNA only contains four different bases, means that the 'signal-to-noise ratio' in protein sequence alignments is much better than in alignments of DNA. Besides this information-theoretical advantage, protein alignments also benefit...... proteins. It is therefore preferable to align coding DNA at the amino acid level and it is for this purpose we have constructed the program RevTrans. RevTrans constructs a multiple DNA alignment by: (i) translating the DNA; (ii) aligning the resulting peptide sequences; and (iii) building a multiple DNA...

Dietary trans fat increases risk for coronary heart disease. In 2006, New York City (NYC) passed the first regulation in the United States restricting trans fat use in restaurants. To assess the effect of the NYC regulation on the trans and saturated fat content of fast-food purchases. Cross-sectional study that included purchase receipts matched to available nutritional information and brief surveys of adult lunchtime restaurant customers conducted in 2007 and 2009, before and after implementation of the regulation. 168 randomly selected NYC restaurant locations of 11 fast-food chains. Adult restaurant customers interviewed in 2007 and 2009. Change in mean grams of trans fat, saturated fat, trans plus saturated fat, and trans fat per 1000 kcal per purchase, overall and by chain type. The final sample included 6969 purchases in 2007 and 7885 purchases in 2009. Overall, mean trans fat per purchase decreased by 2.4 g (95% CI, -2.8 to -2.0 g; P restaurant was located was not associated with changes. Fast-food restaurants that were included may not be representative of all NYC restaurants. The introduction of a local restaurant regulation was associated with a substantial and statistically significant decrease in the trans fat content of purchases at fast-food chains, without a commensurate increase in saturated fat. Restaurant patrons from high- and low-poverty neighborhoods benefited equally. However, federal regulation will be necessary to fully eliminate population exposure to industrial trans fat sources.

2005-01-01

trans-RhCl(CO)(TPPTS) 2 (TPPTS=tris(m-sulfonatophenyl)phosphine) has been intercalated into Zn-Al layered double hydroxides (LDHs) by the method of ion exchange. The structure, composition and thermal stability of the composite material have been characterized by powder X-ray diffraction, Fourier transform infrared and 31 P solid-state magic-angle spinning nuclear magnetic resonance spectroscopy, elemental analysis, thermogravimetry, and differential thermal analysis. The geometry of trans-RhCl(CO)(TPPTS) 2 was fully optimized using the PM3 semiempirical molecular orbital method, and a schematic model for the intercalated species has been proposed. The thermal stability of trans-RhCl(CO)(TPPTS) 2 is significantly enhanced by intercalation, which suggests that such materials may have prospective application as the basis of a supported catalyst system for the hydroformylation of higher olefins

'Unladylike Commotion': Early feminism and nursing's role in gender/trans dialogue.

Science.gov (United States)

Fowler, Marsha D

2017-01-01

From nursing's history comes the impetus and grounding for our current voice in gender/trans dialogue. Modern nursing struggled its way into being against restrictive, unjust, and oppressive social structures. Many of the obstructions and constraints that nurses and nursing leaders faced were shared by the general populace of women, and yet nurses were different from other women. Nurses worked outside the home, caring for strangers, including unrelated men, in a period when women were otherwise confined to the home. Nurses fought for women's suffrage, for child labor laws, for the welfare of factory workers, for garment workers, for unionization, for vaccination, for housing reform, for the humane treatment of mentally ill persons, for access to birth control, for the amelioration of a panoramic terrain of terrible social injustices, and for the control of nursing education, registration, and practice. For 150 years, nursing has been intrinsically, practically, and politically feminist. The hard-fought gains would eventually position nursing in tension with emerging trans issues. And yet, its history is exactly what situates nursing for fruitful participation in the developing trans discourse and to address issues of transinvisibility and unjust social and health structures that impede dignified and respectful health care. © 2017 John Wiley & Sons Ltd.

Effect of Extruding Full-Fat Soy Flakes on Trans Fat Content

Hongxia Feng

2014-01-01

Full Text Available To evaluate the effects of extrusion process on the trans fatty acids (TFAs formation in soybean crude oils, three different extrusion parameters, namely, extrusion temperature (80–160°C, feed moisture (10–26%, and screw speed (100–500 rpm, were carried out. It was found that only five different types of TFAs were detected out using gas chromatography-mass spectrometry. Before the extrusion started, the initial amount of total TFAs was 3.04 g/100 g. However, after extruding under every level of any variable, the total amounts of TFAs were significantly higher than those in the control sample (P<0.05. For example, taking the effect of extrusion temperature into account, we can find that the highest amount of total of trans fatty acid (TTFA was 1.62 times the amount of that in the control sample, whereas the lowest amount of TTFA was 1.54 times the amount of that in the control sample. Importantly, it was observed that the amounts of every type of trans fatty acid were not continuously increasing with the increase of the level of any extrusion variable. This phenomenon demonstrated that the formation and diversification were intricate during extruding process and need to be further studied.

Trans-esterification of poultry skin fat to produce biodiesel

2016-01-01

Chicken skin and its fat are sources of solid waste that are usually not utilized and add solid pollution. This research work deals with the production of useful biodiesel from utilizing the waste chicken (fat and its skins). Waste chicken fat and its skins (sourced from local shops of Hyderabad, Sindh, Pakistan) were extracted and trans-estrification was made. The product of trans-estrification was fatty acid methyl esters (FAME) commonly known as biodiesel. Sodium Hydroxide (NaOH) was used as catalyst and glycerol was obtained as a by-product. The FAME produced was tested for six parameters namely calorific value, cloud point, pour point, flash point, density and viscosity when compared to ASTM E2515-11 standard values. The results of this experiment showed that the calorific value, cloud point, pour point, flash point, density and viscosity values of FAME produced from chicken skin and its fat were close to that of petroleum derived diesel.

2016-03-01

Full Text Available This paper suggests extended algorithms for multilevel trans-Z-source inverter. These algorithms are based on space vector modulation (SVM, which works with high switching frequency and does not generate the mean value of the desired load voltage in every switching interval. In this topology the output voltage is not limited to dc voltage source similar to traditional cascaded multilevel inverter and can be increased with trans-Z-network shoot-through state control. Besides, it is more reliable against short circuit, and due to several number of dc sources in each phase of this topology, it is possible to use it in hybrid renewable energy. Proposed SVM algorithms include the following: Combined modulation algorithm (SVPWM and shoot-through implementation in dwell times of voltage vectors algorithm. These algorithms are compared from viewpoint of simplicity, accuracy, number of switching, and THD. Simulation and experimental results are presented to demonstrate the expected representations.

Carin K. Ingemarsdotter

2017-06-01

Full Text Available Antiviral strategies targeting hijacked cellular processes are less easily evaded by the virus than viral targets. If selective for viral functions, they can have a high therapeutic index. We used RNA trans-splicing to deliver the herpes simplex virus thymidine kinase-ganciclovir (HSV-tk/GCV cell suicide system into HIV-producing cells. Using an extensive in silico bioinformatics and RNA structural analysis approach, ten HIV RNA trans-splicing constructs were designed targeting eight different HIV splice donor or acceptor sites and were tested in cells expressing HIV. Trans-spliced mRNAs were identified in HIV-expressing cells using qRT-PCR with successful detection of fusion RNA transcripts between HIV RNA and the HSV-tk RNA transcripts from six of ten candidate RNA trans-splicing constructs. Conventional PCR and Sanger sequencing confirmed RNA trans-splicing junctions. Measuring cell viability in the presence or absence of GCV expression of HSV-tk by RNA trans-splicing led to selective killing of HIV-producing cells using either 3′ exon replacement or 5′ exon replacement in the presence of GCV. Five constructs targeting four HIV splice donor and acceptor sites, D4, A5, A7, and A8, involved in regulating the generation of multiple HIV RNA transcripts proved to be effective for trans-splicing mediated selective killing of HIV-infected cells, within which individual constructs targeting D4 and A8 were the most efficient.

In this study, the effects of callus age, ultraviolet (UV) irradiation and incubation time were investigated for the induction of trans-resveratrol production in callus cultures of Kalecik karası (Clone 12) Vitis vinifera L. grape cultivar. Part of leaves (~1 cm 2 ) were taken from one year old grapevines grown in greenhouse and then were cultured in Gamborg B-5 media including 2% saccarose, 0.8% agar, 1.0 μM BAP (6-benzylaminopurine) and 0.1 μM 2, 4-D (2, 4-dichlorophenoxy-acetic acid). After the second subculture, 12 and 15 days old callus tissues were exposed to 254 nm UV light at 10 cm distance from the source for 10 and 15 min. Trans-resveratrol was measured at 0, 24, 48 and 72 hours of incubation by using High Pressure Liquid Chromatography (HPLC). Trans-resveratrol concentration of control callus ranged from 0.56 to 0.96 μg g fw -1 . The highest trans-resveratrol production was obtained from 12 and 15 days-old callus irradiated for 10 min. at the 48th hours of incubation (2.42 μg g fw -1 ). Considering the highest value of trans-resveratrol concentration in controls and experiments, it was determined that UV irraditation in Kalecik karası elicitated the trans-resveratrol production by 2.5 times.

Abscisic (ABA)-aldehyde is a precursor to, and 1',4'-trans-ABA-diol a catabolite of, ABA in apple

International Nuclear Information System (INIS)

Rock, C.D.; Zeevaart, J.A.D.

1990-01-01

Previous 18 O labeling studies of abscisic acid (ABA) have shown that apple (Malus domestica Borkh. cv Granny Smith) fruits synthesize a majority of [ 18 O]ABA with the label incorporated in the 1'-hydroxyl position and unlabeled in the carboxyl group (JAD Zeevaart, TG Heath, DA Gage [1989] Plant Physiol 91: 1594-1601). It was proposed that exchange of 18 O in the side chain with the medium occurred at an aldehyde intermediate stage of ABA biosynthesis. We have isolated ABA-aldehyde and 1'-4'-trans-ABA-diol (ABA-trans-diol) from 18 O-labeled apple fruit tissue and measured the extent and position of 18 O incorporation by tandem mass spectrometry. 18 O-Labeling patterns of ABA-aldehyde, ABA-trans-diol, and ABA indicate that ABA-aldehyde is a precursor to, and ABA-trans-diol a catabolite of, ABA. Exchange of 18 O in the carbonyl of ABA-aldehyde can be the cause of loss of 18 O from the side chain of [ 18 O]ABA. Results of feeding experiments with deuterated substrates provide further support for the precursor-product relationship of ABA-aldehyde → ABA → ABA-trans-diol. The ABA-aldehyde and ABA-trans-diol contents of fruits and leaves were low, approximately 1 and 0.02 nanograms per gram fresh weight for ABA-aldehyde and ABA-trans-diol, respectively, while ABA levels in fruits ranged from 10 to 200 nanograms per gram fresh weight. ABA biosynthesis was about 10-fold lower in fruits than in leaves. In fruits, the majority of ABA was conjugated to β-D-glucopyranosyl abscisate, whereas in leaves ABA was mainly hydroxylated to phaseic acid. Parallel pathways for ABA and trans-ABA biosynthesis and conjugation in fruits and leaves are proposed

Exploring the Trans-Neptunian Solar System

Science.gov (United States)

1998-01-01

A profound question for scientists, philosophers and, indeed, all humans concerns how the solar system originated and subsequently evolved. To understand the solar system's formation, it is necessary to document fully the chemical and physical makeup of its components today, particularly those parts thought to retain clues about primordial conditions and processes.] In the past decade, our knowledge of the outermost, or trans-neptunian, region of the solar system has been transformed as a result of Earth-based observations of the Pluto-Charon system, Voyager 2's encounter with Neptune and its satellite Triton, and recent discoveries of dozens of bodies near to or beyond the orbit of Neptune. As a class, these newly detected objects, along with Pluto, Charon, and Triton, occupy the inner region of a hitherto unexplored component of the solar system, the Kuiper Belt. The Kuiper Belt is believed to be a reservoir of primordial objects of the type that formed in the solar nebula and eventually accreted to form the major planets. The Kuiper Belt is also thought to be the source of short-period comets and a population of icy bodies, the Centaurs, with orbits among the giant planets. Additional components of the distant outer solar system, such as dust and the Oort comet cloud, as well as the planet Neptune itself, are not discussed in this report. Our increasing knowledge of the trans-neptunian solar system has been matched by a corresponding increase in our capabilities for remote and in situ observation of these distant regions. Over the next 10 to 15 years, a new generation of ground- and space-based instruments, including the Keck and Gemini telescopes and the Space Infrared Telescope Facility, will greatly expand our ability to search for and conduct physical and chemical studies on these distant bodies. Over the same time span, a new generation of lightweight spacecraft should become available and enable the first missions designed specifically to explore the icy

International work on refrigerants is aiming at phasing out HFC. The solution might be natural refrigerants. Within 15-20 years, when present heat pumps for district heating in Sweden are likely not in service any longer, it might still be good economy to install new heat pumps since only the machines need to be replaced. This report describes the possibilities to use natural refrigerants. A first screening resulted in further study on some hydrocarbons, ammonia and carbon dioxide. Water was considered to require too large volumes. In present plants it is practically not possible to use any natural refrigerants, partly because the compressors are not adapted. In new plants the situation is different. Today it is technically possible to install new heat pumps in the studied size, 15 MW{sub th}, using ammonia or hydrocarbons as refrigerant. But likely it is very difficult to get permits from authorities since the refrigerants are toxic or highly flammable. There is substantial international research on using carbon dioxide, and this refrigerant is also used in some applications. Carbon dioxide is used at high pressure and in a trans-critical process. Surprisingly, it turned out that one compressor manufacturer considers it possible to supply a heat pump for district heating within 5 years. This development has taken place in Russia, mainly for domestic use. Thus, within 15 to 20 years there will probably exist a technique where carbon dioxide is used. However, more development is needed. Additionally, low district heating return temperatures are also needed to get an acceptable COP. The investment cost for a heat pump installation is considered to be approx. 30 % higher when using ammonia or propane compared to using R134a. When using carbon dioxide there is in the longer run potential to get lower cost than for R134a. The COPs are almost identical if the systems are properly designed. In the carbon dioxide case the COP is somewhat lower, but has a potential for

The few previous studies investigating regulation of gender in trans-specific healthcare are mainly based on text material and interviews with care-providers or consist solely of theoretical analyses. There is a lack of studies analysing how the regulation of gender is expressed in the care-seeker's own experiences, especially in a Nordic context. The aim of this study is to analyse narratives of individuals with trans experiences (sometimes called transgender people) to examine how gender performances can be regulated in trans-specific care in Sweden. The conceptual framework is inspired by trans studies, a Foucauldian analysis of power, queer phenomenology and the concept of cisnormativity. Fourteen interviews with people with trans experiences are analysed with constructivist grounded theory. The participants' experiences indicate that gender is constructed as norm-conforming, binary and stable in trans-specific healthcare. This gendered position is resisted, negotiated and embraced by the care-seekers. Norms and discourses both inside and outside trans-specific care contribute to the regulation and limit the room for action for care-users. We conclude that a trans-specific care that has a confirming approach to its care-users, instead of the current focus on gender norm conformity, has the potential to increase the self-determination of gender performance and increase the quality of care.

A novel core-shell molecularly imprinting microspheres (MIMs) with trans-resveratrol as the template molecule; acrylamide (AA) as functional monomer and ethylene glycol dimethacrylate (EGDMA) as cross-linker, was prepared based on SiO 2 microspheres with surface imprinting technique. These core-shell trans-resveratrol imprinted microspheres were characterized by infrared spectra (IR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and high performance liquid chromatography (HPLC). The results showed that these core-shell imprinted microspheres, which take on perfect spherical shape with average shell thickness of 150 nm, exhibit especially selective recognition for trans-resveratrol. These imprinted microspheres were applied as solid-phase extraction materials for selective extraction of trans-resveratrol from giant knotweed extracting solution successfully.

Swedish district heating - owners, prices and profitability

International Nuclear Information System (INIS)

Andersson, Sofie; Werner, S.

Owners, prices and profitability are examined in this report for 152 Swedish district heating companies during 1999. Only public information available has been used: Prices from a national annual consumer study, energy supplied, lengths of district heating pipes installed, and average prices for energy supplied. These companies are responsible for 96 % of all district heat supplied in Sweden. District heating systems owned by municipalities were responsible for 65 % of all district heat supply, while the share of power companies was 34 %. Other private owners accounted for 1 %. Only 12 % of the board members are women and more than 40 % of the companies have no woman in the board. The prices gathered by the annual consumer study are good estimates of the price level of district heating in Sweden. The average revenues are only 4,1 % lower than the effective average of prices gathered. Price of district heating decrease with size and market share. Use of combined heat and power plants decrease prices slightly. Lower prices with size can mainly be explained by lower energy supply costs. Calculated rates of return in relation to calculated replacement values increase slightly by size and are almost independent of age and market share. The purport of these conclusions is that the district heating companies share the cost reduction from size with their customers, while the whole benefit from high market shares is repaid to the customers. Calculated rates of return vary among the owner groups examined. Lower rates are accepted by municipalities, while power companies have higher rates at the average costs used. Total replacement costs for the 152 companies has been estimated to 89 billion Swedish crowns or 10 billion Euro. Only correlation analyses using one dimension have been used in this study. A higher degree of quality can be obtained by using multi-dimensional analyses

There is excellent evidence that a dynamical instability in the early solar system led to gravitational interactions between the giant planets and trans-Neptunian planetesimals. Giant planetary migration triggered by the instability dispersed a disk of primordial trans-Neptunian object (TNOs) and created a number of small body reservoirs (e.g. the Kuiper Belt, scattered disk, irregular satellites, and the Jupiter/Neptune Trojan populations). It also injected numerous bodies into the main asteroid belt, where modeling shows they can successfully reproduce the observed P and D-type asteroid populations.

The Studsvik power transient programs Demo-Ramp II and Trans-Ramp I

The Studsvik Demo-Ramp II och Trans-Ramp I are internationally sponsored research programs. The main objectives are similar in both programs: to study the effects on the PCI/SCC failure process of short time power transients, above the failure threshold where cladding failure (FP leakage) is expected to occur after a sufficient hold time. Demo-Ramp II is completed, whereas, at present, Trans-Ramp I is in progress. Test fuel rods of standard BWR design are used. The fuel rods have been base-irradiated in a power reactor (burn-up in the range 18 to 29 MWd/kg U) and subsequently ramp tested in the R2 reactor. Extensive examinations of the rods have been performed. In the Demo-Ramp II program a large number of incipient cladding cracks were observed to be formed more rapidly than expected, based on previous knowledge. It was possible to operate one rod for a very short time above the failure threshold without SCC crack formation. One objective of the Trans-Ramp I program is to define more closely the power-time region above the failure threshold where the rods remain intact after power transients. (author)

Resveratrol has been widely studied in terms of it's potential to slow the progression of many diseases. But little is known about the mechanism of action in neuropathic pain. Neuropathic pain is the main type of chronic pain associated with tissue injury. Calcium channels and calcium/caffeine-sensitive pools are associated with analgesic pathway involving neuropathic pain. Our previous study suggested that the antinociceptive effect of resveratrol was involved in Ca 2+ /calmodulin-dependent signaling in the spinal cord of mice. The aim of this study was to explore the involvement of Ca 2+ in analgesic effects of trans-resveratrol in neuropathic pain and signal pathway in hippocampus. Hot plate test was used to assess antinociceptive response when mice were treated with trans-resveratrol alone or in combination with Mk 801, nimodipine, CaCl 2 , ryanodine or EGTA. The effects of trans-resveratrol and the combination on Ca 2+ /calmodulin-dependent protein kinase II (CaMKII) and BDNF (brain-derived neurotrophic factor) expression in hippocampus were also investigated. The results showed that trans-resveratrol increased paw withdraw latency in the hot plate test. The effect of resveratrol was enhanced by Mk 801 and nimodipine. Central administration of Ca 2+ , however, abolished the antinociceptive effects of resveratrol. In contrast, centrally administered EGTA or ryanodine improved trans-resveratrol induced antinociception. There was a significant increase in p-CaMKII and BDNF expression in the hippocampus when resveratrol were combined with Mk 801, nimodipine, ryanodine and EGTA. Administration of CaCl 2 blocked changes in p-CaMKII and BDNF levels in the hippocampus. These findings suggest that trans-resveratrol exerts the effects of antinociception through regulation of calcium channels and calcium/caffeine-sensitive pools.

tRNA Is the Source of Low-Level trans-Zeatin Production in Methylobacterium spp.†‡

Pink-pigmented facultatively methylotrophic bacteria (PPFMs), classified as Methylobacterium spp., are persistent colonizers of plant leaf surfaces. Reports of PPFM-plant dialogue led us to examine cytokinin production by PPFMs. Using immunoaffinity and high-performance liquid chromatography (HPLC) purification, we obtained 22 to 111 ng of trans-zeatin per liter from culture filtrates of four PPFM leaf isolates (from Arabidopsis, barley, maize, and soybean) and of a Methylobacterium extorquens type culture originally recovered as a soil isolate. We identified the zeatin isolated as the trans isomer by HPLC and by a radioimmunoassay in which monoclonal antibodies specific for trans-hydroxylated cytokinins were used. Smaller and variable amounts of trans-zeatin riboside were also recovered. trans-Zeatin was recovered from tRNA hydrolysates in addition to the culture filtrates, suggesting that secreted trans-zeatin resulted from tRNA turnover rather than from de novo synthesis. The product of the miaA gene is responsible for isopentenylation of a specific adenine in some tRNAs. To confirm that the secreted zeatin originated from tRNA, we mutated the miaA gene of M. extorquens by single exchange of an internal miaA fragment into the chromosomal gene. Mutant exconjugants, confirmed by PCR, did not contain zeatin in their tRNAs and did not secrete zeatin into the medium, findings which are consistent with the hypothesis that all zeatin is tRNA derived rather than synthesized de novo. In germination studies performed with heat-treated soybean seeds, cytokinin-null (miaA) mutants stimulated germination as well as wild-type bacteria. While cytokinin production may play a role in the plant-PPFM interaction, it is not responsible for stimulation of germination by PPFMs. PMID:11889088

Full Text Available After the liberation of Nis from the Turks which took place on January 11th, 1878, there were two military hospitals: one was next to The Skull Tower and the other on the road to Leskovac and there was Islahana the civil institution which was not the forerunner of the district hospital in Nis. At first, they founded the military hospital in Nis in 1878 and then they founded The District Hospital on July 17th in 1881. The first director of the District hospital was Anton Zajicek. He is also the first graduated medical doctor in Nis. The District Hospital was situated on the left bank of the Nisava river in a private house.

Full Text Available A general, five step method for the synthesis of 3-alkylfentanyl analogues (i.e., cis and trans 3-alkyl-4-anilidopiperidines 6.1–6.6 has been developed. The starting N-phenethyl-4-piperidone 1 was first converted into the cyclohexylimine derivative 2, a-deprotonated with butyllithium and the resulting imine anion efficiently monoalkylated with primary and secondary alkyl halides. After mild acid hydrolysis, the obtained 3-alkyl-4-piperidones 3.1–3.6 were isolated in good yields (79–85 %, then condensed with aniline to form imines 4.1–4.6. Subsequent reduction of the imines (LiAlH4/THF yielded cis/trans mixtures of 3-alkyl-4-anilinopiperidines 5.1–5.6. Quantitative separation of the diastereoisomers by column chromatography of Al2O3 gave pure cis 5.1–5.6 (29–51 % yield and trans 5.1–5.6 (19–27 % yield, with the cis/trans ratio in the range 7/3–6/4. The synthesis was concluded by N-acylation of the purified 5.1–5.6, with propionyl chloride, to afford cis and trans 3-alkyl-4-anilidopiperidines 6.1–6.6 (~95 % yield, as monooxalate salts. No enatioseparation was attempted at any stage. The relative cis/trans stereochemistry was provisionally assigned from the 1H-NMR spectra. Of the twelve synthesized 3-alkylfentanyls, ten compounds (two known and eight novel derivatives, all as the monooxalate salts were preliminarily tested as analgesics in rats, comparing the potency to fentanyl. Except for the known (±-cis-3-Me fentanyl 6.1cis, (8 × fentanyl, and the novel (±-cis-3-Et fentanyl 6.2cis, (1.5 × fentanyl, all of the others were less active than fentanyl or inactive. Some tentative conclusions on the structure-activity relationship (SAR in this series of derivatives have been made.

Trans-oral robotic surgery in oropharyngeal carcinoma - A guide for general practitioners and patients.

Science.gov (United States)

Liu, Wendy Sijia; Limmer, Alex; Jabbour, Joe; Clark, Jonathan

Trans-oral robotic surgery (TORS) is emerging as a minimally invasive alternative to open surgery, or trans-oral laser surgery, for the treatment of some head and neck pathologies, particularly oropharyngeal carcinoma, which is rapidly increasing in incidence. In this article we review current evidence regarding the use of TORS in head and neck surgery in a manner relevant to general practice. This information may be used to facilitate discussion with patients. Compared with open surgery or trans-oral laser surgery, TORS has numerous advantages, including no scarring, less blood loss, fewer complications, lower rates of admission to the intensive care unit, and reduced length of hospitalisation. The availability of TORS in Australia is currently limited and, therefore, public awareness about TORS is lacking. Details regarding the role of TORS and reliable, up-to-date, patient-friendly information sources are discussed in this article.

Relic gravitational wave spectrum, the trans-Planckian physics and Horava-Lifshitz gravity

International Nuclear Information System (INIS)

We calculate the spectrum of the relic gravitational wave due to the trans-Planckian effect in which the standard linear dispersion relations may be modified. Of the modified dispersion relations suggested in the literature which has investigated the trans-Planckian effect, we especially use the Corley-Jacobson dispersion relations. The Corley-Jacobson-type modified dispersion relations can be obtained from Horava-Lifshitz gravity which is non-relativistic and UV complete. Although it is not clear how the transitions from Horava-Lifshitz gravity in the UV regime to Einstein gravity in the IR limit occur, we assume that the Horava-Lifshitz gravity regime is followed by the inflationary phase in Einstein gravity.

Is Swedish district heating operating on an integrated market? – Differences in pricing, price convergence, and marketing strategy between public and private district heating companies

Åberg, M.; Fälting, L.; Forssell, A.

2016-01-01

The deregulation of the Swedish electricity market in 1996 made it possible to operate municipal district heating commercially. Until that time district heating had been organized mainly as municipal utilities. After 1996 district heating is instead expected to function on a market. In competitive and integrated markets, prices are expected to be equal, or converging. To find out if district heating operates on an integrated market the differences in price levels, price convergence, price strategy, and business goals, among municipal, private and state owned district heating companies are investigated. Price statistics was used along with results from a questionnaire that was answered by representatives for 109 Swedish district heating companies. The results show that prices among district heating systems do not converge significantly and that variations in prices among municipal systems are larger than among private and state owned systems. Furthermore, despite the fact that district heating is supposed to be commercial, a vast majority of district heating companies apply cost-based pricing and not market pricing. The municipal companies give priority to political goals before financial goals. The conclusion is that a Swedish integrated market for heat has not yet evolved, and some district heating price-controlling mechanism is necessary. - Highlights: • Price statistics and owner type data were used along with results from a questionnaire. • Results show that prices among district heating systems do not converge. • Municipal district heating companies still apply cost-based pricing to a large extent. • District heating companies are not operating on an integrated market for heat. • Some price-controlling mechanism for district heating is necessary.
