    Full Text Available O gênero Lepidagathis apresenta distribuição pantropical com cerca de 100 espécies. No Brasil ocorrem 16 espécies, a maioria nas regiões Centro - Oeste e Sudeste. O estudo foi realizado em sub - bosque de remanescente florestal do município de Tangará da Serra - MT e teve como objetivo analisar a fenologia de floração, descrever a morfologia e biologia floral, verificar os visitantes florais e avaliar o sistema e o sucesso reprodutivo por meio de polinizações manuais. Lepidagathis sessilifolia apresenta inflorescências espiciformes, terminais, com cálice de cor rósea vistosa e corola de coloração branco-rósea. A floração ficou restrita aos meses de março a abril, durante a estação chuvosa. A senescência floral ocorreu após 24 ou 48 horas. A viabilidade dos grãos de pólen foi elevada (92,5%. O único polinizador observado visitando as flores de L. sessilifolia foi a abelha Partamona nhambiquara (Apidae - Meliponini. O sistema reprodutivo misto da espécie é caracterizado pela formação de frutos por meio de agamospermia, autopolinização e polinização cruzada. Esse sistema reprodutivo flexível é vantajoso, pois, garante a manutenção da espécie na área de estudo mesmo na ausência de polinizadores.The genus Lepidagathis has pantropical distribution and about 100 species, 16 occurring in Brazil, mostly in the Midwest and Southeast regions. The research was carried out to evaluate in the understory of a forest remnant in Tangará da Serra County - MT to examine the flowering phenology, describe the floral morphology and biology and verify the floral visitors to evaluate the system and reproductive success through hand pollination tests. Lepidagathis sessilifolia shows spiciform and terminal inflorescence with calyx of pink color and corolla whitish-pink. Flowering was restricted from March to April, during the rainy season. Floral senescence occurred after 24 or 48 hours. The viability of pollen grains was high (92.5%. The effective pollinator of L. sessilifolia was Partamona nhambiquara (Apidae - Meliponini. The mixed mating system of the species is characterized by the formation of fruits by agamospermy, self and cross-pollination, spontaneous self-pollination, agamospermy and outcrossing. This flexible reproductive system is advantageous because it ensures the maintenance of species in the study area even in the absence of pollinators.

    Full Text Available Changes to the International Code of Botanical Nomenclature are decided on every 6 years at Nomenclature Sections associated with International Botanical Congresses (IBC. The XVIII IBC was held in Melbourne, Australia; the Nomenclature Section met on 18-22 July 2011 and its decisions were accepted by the Congress at its plenary session on 30 July. Several important changes were made to the Code as a result of this meeting that will affect publication of new names. Two of these changes will come into effect on 1 January 2012, some months before the Melbourne Code is published. Electronic material published online in Portable Document Format (PDF with an International Standard Serial Number (ISSN or an International Standard Book Number (ISBN will constitute effective publication, and the requirement for a Latin description or diagnosis for names of new taxa will be changed to a requirement for a description or diagnosis in either Latin or English. In addition, effective from 1 January 2013, new names of organisms treated as fungi must, in order to be validly published, include in the protologue (everything associated with a name at its valid publication the citation of an identifier issued by a recognized repository (such as MycoBank.

    Based on the results of the survey of the potential quantity supplied of overseas resource which was made from FY 1981 to FY 1983, the paper predicted the world methanol supply plan, changes in the oil situation, economical efficiency of methanol and the competitive power with petroleum products, etc., and studied the time of potential supply, areas of potential supply and supply potential of power generation use methanol during the period toward 2000. In case the comparatively low crude oil price is predicted due to the energy supply/demand (Scenario A), the supply potential of power generation use methanol in four projects on methanol production taken up as trial calculation example is considered very low. Even in case the comparatively high crude oil price is predicted (Scenario C), it is in 1989 that the methanol market price becomes equivalent in heat quantity to the crude oil price. It is difficult to expect the potential before 1989. In case of the intermediate case between Scenario A and Scenario C (Scenario B), it is in 1993 that the methanol price becomes equivalent in heat quantity to the crude oil price. It is difficult to expect the potential before 1993. (NEDO)

    For the study of the potential supply amount of methanol as power generation use fuel, survey was conducted as case study on the following: Victorian brown coal of Australia, conversion of Arun natural gas to methanol at site in Indonesia, political/social/technical restrictions, supply scale, economical efficiency, etc. at the time of the supply to Japan. For the calculation of economical efficiency, it was assumed that the scale of methanol production was 5,000 t/d, that the plant operated years were 20 and that the price of acquisition of raw material was US$4-10/t in Victorian brown coal and US$1-4/t in Arun natural gas. As a result of the study, in the case of natural gas base methanol, the CIF Japan is lower than CIF prices of LNG and crude oil in case the price of acquisition of raw material is US$1/t, but is higher than those in case the price is US$2/t. In the case of brown coal base methanol, it was found that the CIF Japan could not be lower than CIF prices of LNG and crude oil even in case the price of acquisition of raw material is US$4/t, which is the lowest.

    Methods. Participants were 19,456 cigarette smokers interviewed during the longitudinal International Tobacco Control (ITC Four-Country Survey in Canada, USA, UK, and Australia. Results. “Predominant” RYO use (i.e., >50% of cigarettes smoked increased significantly in the UK and USA as a proportion of all cigarette use (both P<.001 and in all countries as a proportion of any RYO use (all P<.010. Younger, financially stressed smokers are disproportionately contributing to “some” use (i.e., ≤50% of cigarettes smoked. Relative cost was the major reason given for using RYO, and predominant RYO use is consistently and significantly associated with low income. Conclusions. RYO market trends reflect the price advantages accruing to RYO (a product of favourable taxation regimes in some jurisdictions reinforced by the enhanced control over the amount of tobacco used, especially following the impact of the Global Financial Crisis; the availability of competing low-cost alternatives to RYO; accessibility of duty-free RYO tobacco; and tobacco industry niche marketing strategies. If policy makers want to ensure that the RYO option does not inhibit the fight to end the tobacco epidemic, especially amongst the disadvantaged, they need to reduce the price advantage, target additional health messages at (young RYO users, and challenge niche marketing of RYO by the industry.

    Excise duties on roll-your-own (RYO) tobacco, which are generally based on RYO cigarettes containing 1 g of tobacco, are lower than duties on factory-made (FM) cigarettes. This provides a price incentive for smokers to switch to RYO, the use of which is increasing across Europe. To effectively approximate duties on the two types of products, accurate data on the weight of RYO cigarettes are required. We provide updated information on RYO use and RYO cigarette weight across Europe. From a representative face-to-face survey conducted in 2010 in 18 European countries (Albania, Austria, Bulgaria, Czech Republic, Croatia, England, Finland, France, Greece, Hungary, Ireland, Italy, Latvia, Poland, Portugal, Romania, Spain and Sweden), we considered data from 5158 current smokers aged 15 years or above, with available information on daily consumption of FM and RYO cigarettes separately. In Europe, 10.4% of current smokers (12.9% of men and 7.5% of women) were 'predominant' RYO users (i.e. >50% of cigarettes smoked). This proportion was highest in England (27.3%), France (16.5%) and Finland (13.6%). The median weight of one RYO cigarette is 0.75 g (based on 192 smokers consuming exclusively RYO cigarettes). The proportion of RYO smokers is substantial in several European countries. Our finding on the weight of RYO cigarettes is consistent with the scientific literature and industry documents showing that the weight of RYO cigarettes is substantially lower than that of FM ones. Basing excise duties on RYO on an average cigarette weight of 0.75 g rather than 1 g would help increase the excise levels to those on FM cigarettes.

    Full Text Available Abstract Background Despite the apparent decline in the popularity of roll-your-own (RYO cigarettes over the past few decades, RYO tobacco products are widely available and used by a substantial number of adult smokers. Considering research has yet to examine the prevalence of RYO tobacco use among youth populations, this manuscript examines the prevalence of RYO tobacco use and factors associated with RYO use in a nationally representative sample of youth smokers from Canada. Methods This study used data collected from 3,630 current smokers in grades 9 to 12 as part of the 2008-09 Canadian Youth Smoking Survey (YSS. Descriptive analyses of the sample demographic characteristics, smoking status, cigarettes per day, weekly spending money, and frequency of marijuana use were examined by RYO tobacco ever use and RYO tobacco current use. Two logistic regression models were used to examine factors associated with RYO tobacco ever use and RYO tobacco current use. Results We identified that 51.2% of current smokers were RYO ever users and 24.2% were RYO current users. The prevalence of RYO current users was highest in Atlantic Canada (40.1% and lowest in Quebec (12.3%. RYO current users were more likely to be male (OR 1.27, to be daily smokers (OR 1.75, to use marijuana once a month or more (OR 2.74, and to smoke 11 or more cigarettes per day (OR 6.52. RYO current users were less likely to be in grade 11 (OR 0.65 or grade 12 (OR 0.40 and less likely to have between $20 to $100 (OR 0.44 or more than $100 (OR 0.45 of disposable income. Conclusions Developing a better understanding of RYO tobacco use among youth is important for advancing population-level tobacco control prevention strategies and cessation programs. We identified that RYO tobacco use is not a negligible problem among Canadian youth. Ongoing research is needed to continue monitoring the prevalence of RYO use among youth and the factors associated with its use, but to also monitor if this

    Roll-your-own (RYO) cigarette use has been subject to relatively limited research, particularly in developing countries. This paper seeks to describe RYO use in Thailand and Malaysia and relate RYO use to smokers' knowledge of the harmfulness of tobacco. Data come from face-to-face surveys with 4,004 adult smokers from Malaysia (N = 2,004) and Thailand (N = 2000), collected between January and March 2005. The prevalence of any use of RYO cigarettes varied greatly between Malaysia (17%) and Thailand (58%). In both countries, any RYO use was associated with living in rural areas, older average age, lower level of education, male gender, not being in paid work, slightly lower consumption of cigarettes, higher social acceptability of smoking, and positive attitudes toward tobacco regulation. Among RYO users, exclusive use of RYO cigarettes (compared with mixed use) was associated with older age, female gender (relatively), thinking about the enjoyment of smoking, and not making a special effort to buy cheaper cigarettes if the price goes up. Finally, exclusive RYO smokers were less aware of health warnings (RYO tobacco carries no health warnings), but even so, knowledge of the health effects of tobacco was equivalent.

  10. Do consumers of manufactured cigarettes respond differently to price changes compared with their Roll-Your-Own counterparts? Evidence from New Zealand.

    Price-based mechanisms are an important tobacco cessation policy tool in New Zealand (NZ) and so measurement of smokers' reaction to price changes is crucial in determining efficacy of this approach. Although approximately two-thirds of NZ tobacco demand is for manufactured cigarettes (MC) and one-third is for Roll-Your-Own (RYO) tobacco, previous price elasticity estimates have ignored differences between RYO tobacco and MC consumers. We employ a seemingly unrelated regression econometric approach applied to quarterly data over the period 1991-2011 to estimate price elasticities of demand separately for MC and RYO tobacco. Estimate of price elasticity of demand for MC is -1.033, and -0.441 for RYO tobacco. RYO tobacco is an inferior good; a 1% increase in average weekly income is associated with a 0.8% reduction in demand. RYO tobacco is a substitute for MC; a 1% increase in the price of MC is associated with a 0.867% increase in demand for RYO tobacco. There is significantly different price responsiveness across the two tobacco product types. MC smokers react far more strongly to price increases compared with RYO tobacco smokers. These findings suggest that pricing mechanisms may be more effective for reducing MC demand than for RYO tobacco. However, substitution between products means that this pricing effect is muted by the uptake of RYO tobacco use. Cessation policy specific to RYO use should be designed to target this growing group.

    The paper studied a scenario of the demand for power generation use methanol in Japan by grasping the situation of the utilization of methanol as fuel in the world, studying a scenario of power supply and the positioning of methanol power generation in Japan, doing a trial calculation of the breakeven price of power generation use methanol, etc. As to the usability of power generation use methanol as fuel, in the use for the reformed gas turbine and fuel cell, there is a possibility of making up for the disadvantage in fuel price by future technical development. For the fuel conversion at existing coal-fired power plants and the application of methanol to combined cycle and newly-installed boiler, it is necessary to have a substantial drop in methanol price. Taking an advantage that methanol can be transported in small size and easily be stored, methanol can possibly be used as fuel for dispersed power sources. The potential demand for petroleum substituting methanol is estimated at approximately 25 million t/y, assuming it to be 1/2 of the petroleum consumption amount. The present methanol market in the world is not so large for quantity use as fuel, and for the introduction, therefore, it is necessary to secure flexibility in supply. (NEDO)

  13. Fiscal and policy implications of selling pipe tobacco for roll-your-own cigarettes in the United States.

    The Federal excise tax was increased for tobacco products on April 1, 2009. While excise tax rates prior to the increase were the same for roll-your-own (RYO) and pipe tobacco, the tax on pipe tobacco was $21.95 per pound less than the tax on RYO tobacco after the increase. Subsequently, tobacco manufacturers began labeling loose tobacco as pipe tobacco and marketing these products to RYO consumers at a lower price. Retailers refer to these products as "dual purpose" or "dual use" pipe tobacco. Data on tobacco tax collections comes from the Alcohol and Tobacco Tax and Trade Bureau. Joinpoint software was used to identify changes in sales trends. Estimates were generated for the amount of pipe tobacco sold for RYO use and for Federal and state tax revenue lost through August 2011. Approximately 45 million pounds of pipe tobacco has been sold for RYO use from April 2009 to August 2011, lowering state and Federal revenue by over $1.3 billion. Marketing pipe tobacco as "dual purpose" and selling it for RYO use provides an opportunity to avoid paying higher cigarette prices. This blunts the public health impact excise tax increases would otherwise have on reducing tobacco use through higher prices. Selling pipe tobacco for RYO use decreases state and Federal revenue and also avoids regulations on flavored tobacco, banned descriptors, prohibitions on shipping, and reporting requirements.

    In Zambia, the number of cigarette users is growing, and the lack of strong tax policies is likely an important cause. When adjusted for inflation, levels of tobacco tax have not changed since 2007. Moreover, roll-your-own (RYO) tobacco, a less-costly alternative to factory-made (FM) cigarettes, is highly prevalent. We modelled the probability of FM and RYO cigarette smoking using individual-level data obtained from the 2012 and 2014 waves of the International Tobacco Control (ITC) Zambia Survey. We used two estimation methods: the standard estimation method involving separate random effects probit models and a method involving a system of equations (incorporating bivariate seemingly unrelated random effects probit) to estimate price elasticities of FM and RYO cigarettes and their cross-price elasticities. The estimated price elasticities of smoking prevalence are -0.20 and -0.03 for FM and RYO cigarettes, respectively. FM and RYO are substitutes; that is, when the price of one of the products goes up, some smokers switch to the other product. The effects are stronger for substitution from FM to RYO than vice versa. This study affirms that increasing cigarette tax with corresponding price increases could significantly reduce cigarette use in Zambia. Furthermore, reducing between-product price differences would reduce substitution from FM to RYO. Since RYO use is associated with lower socioeconomic status, efforts to decrease RYO use, including through tax/price approaches and cessation assistance, would decrease health inequalities in Zambian society and reduce the negative economic consequences of tobacco use experienced by the poor. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    For the purpose of using methanol as power generation use fuel, the paper carried out of the conceptual design of methanol reformed high efficiency gas turbine and the evaluation study of economical efficiency. The methanol reformed gas turbine is to recover the heat from turbine flue gas and to improve thermal efficiency by using the fact that the vapor reforming reaction or decomposition reaction of methanol advance endothermicly at low temperature between 250 and 350 degrees C. It was judged that the combination with the existing technology made the practical application possible and that it was appropriate to adopt the regenerative gas turbine/water-injection and reforming (RGGT/WI and R). As a result of the trial calculation of construction cost of RGGT/WI and R and calculation of power generation cost, RGGT/WI and R became more profitable than the simple open gas turbine at a capacity ratio of 10% or more, and became more profitable than the combined cycle at all capacity ratios. In the use of RGGT/WI and R, which uses methanol as fuel, SOx is not included in flue gas, and the NOx included is estimated at 35ppm or so. The amount satisfies the standard according to the boiler using fluid as fuel. (NEDO)

    Current smoking prevalence in Thailand decreased from 1991 to 2004 and since that time the prevalence has remained flat. It has been suggested that one of the reasons that the prevalence of current smoking in Thailand has stopped decreasing is due to the use of RYO cigarettes. The aim of this study was to examine characteristics of users of manufactured and RYO cigarettes and dual users in Thailand, in order to determine whether there are differences in the characteristics of users of the different products. The 2009 Global Adult Tobacco Survey (GATS Thailand) provides detailed information on current smoking patterns. GATS Thailand used a nationally and regionally representative probability sample of 20,566 adults (ages 15 years and above) who were chosen through stratified three-stage cluster sampling and then interviewed face-to-face. The prevalence of current smoking among Thai adults was 45.6% for men and 3.1% for women. In all, 18.4% of men and 1.0% of women were current users of manufactured cigarettes only, while 15.8% of men and 1.7% of women were current users of RYO cigarettes only. 11.2% of men and 0.1% of women used both RYO and manufactured cigarettes. Users of manufactured cigarettes were younger and users of RYO were older. RYO smokers were more likely to live in rural areas. Smokers of manufactured cigarettes appeared to be more knowledgeable about the health risks of tobacco use. However, the difference was confounded with age and education; when demographic variables were controlled, the knowledge differences no longer remained. Smokers of manufactured cigarettes were more likely than dual users and those who used only RYO to report that they were planning on quitting in the next month. Users of RYO only appeared to be more addicted than the other two groups as measured by time to first cigarette. There appears to be a need for product targeted cessation and prevention efforts that are directed toward specific population subgroups in Thailand and

    To assess changes in smoking prevalence and study roll-your-own (RYO) tobacco and e-cigarette use in the Galician population between 2007 and 2015. Data were obtained from five independent, cross-sectional studies carried out in Galicia (Spain) between 2007-2015 in the population aged 16 and over (n=8,000/year). Prevalence of use was estimated, with 95% confidence intervals, overall, according to sex and by age group, area of residence and level of education. Smoking prevalence decreased from 25.4% in 2007 to 21.8% in 2015. In 2007, 1.8% of current smokers declared that they had smoked RYO tobacco, compared to 18.6% in 2015. Among smokers, RYO tobacco consumption increased across all demographic groups. In both 2014 and 2015, ever use of e-cigarettes was 0.7%. E-cigarette use was more frequent in urban settings. Smoking prevalence decreased in Galicia between 2007 and 2015, and there has been rapid growth in the prevalence of RYO tobacco use. Although smokers are more likely to use e-cigarettes, both former and never smokers declared their use. The boom of RYO cigarettes and the emergence of e-cigarettes highlight the importance of having continuous surveillance systems to identify smoking behavioural changes. Copyright © 2016 SESPAS.

    Background Little research has been done to examine whether smokers switch to illegal or roll-your-own (RYO) cigarettes in response to a change in their relative price. Objective This paper explores how relative prices between three cigarette forms (manufactured legal, manufactured illegal, and RYO cigarettes) are associated with the choice of one form over another after controlling for covariates, including sociodemographic characteristics, smokers’ exposure to anti-smoking messaging, health warning labels, and tobacco marketing. Methods Generalized estimating equations (GEE) were employed to analyse the association between the price ratio of two different cigarette forms and the usage of one form over the other. Findings A 10% increase in the relative price ratio of legal to RYO cigarettes is associated with 4.6% increase in the probability of consuming RYO over manufactured legal cigarettes (P≤0.05). In addition, more exposure to anti-smoking messaging is associated with lower odds of choosing RYO over manufactured legal cigarettes (P≤0.05). Non-significant associations exist between the manufactured illegal to legal cigarette price ratios and choosing manufactured illegal cigarettes, suggesting that smokers do not switch to manufactured illegal cigarettes as prices of legal ones increase. However, these non-significant findings may be due to lack of variation in the price ratio measures. In order to improve the effectiveness of increased taxes and prices in reducing smoking, policy makers need to narrow price variability in the tobacco market. Moreover, increasing anti-smoking messaging reduces tax avoidance in the form of switching to cheaper RYO cigarettes in Uruguay. PMID:25740084

    Introduction: In this study, we aimed to examine, in Thailand, the impact on smokers? reported awareness of and their cognitive and behavioral reactions following the change from text-only to pictorial warnings printed on cigarette packs. We also sought to explore differences by type of cigarette smoked (roll-your-own [RYO] vs. factory-made [FM] cigarettes). Methods: Data came from the International Tobacco Control Southeast Asia Survey, conducted in Thailand and Malaysia, where a representat...

    Cigarette consumption has declined in the USA. However, cigar consumption has increased. This may be due in part to some cigarette smokers switching to filtered cigars as a less expensive substitute for cigarettes. Additionally, some cigarette smokers may perceive and consume little filtered cigars as cigarettes. The purpose of this study was to determine how cigarette smokers classify tobacco products when presented with photographs of those products. An online survey was conducted with a sample of 344 self-identified cigarette smokers. Respondents were presented with pictures of various types of tobacco products, both with and without packaging, and then asked to categorise them as either a cigarette, little cigar, cigarillo, cigar or machine-injected roll-your-own cigarette (RYO). Respondents were also asked about their tobacco use and purchasing behaviour. Overall, respondents had difficulty distinguishing between cigarettes, little cigars, cigarillos and RYO. When presented with images of the products without packaging, 93% of respondents identified RYO as a cigarette, while 42% identified a little cigar as a cigarette. Additionally, respondents stated that they would consider purchasing little cigars as substitutes for cigarettes because of the price advantage. The results of this survey suggest that when presented with photographs of tobacco products, large proportions of current smokers were unable to differentiate between cigarettes, little cigars, cigarillos, RYO and cigars. Findings have implications for existing public health efforts targeting cigarette smokers, and underscore the need to review current definitions of tobacco products and federal excise taxes on such products.

    Little is known about cigarette pricing and brand loyalty in sub-Saharan Africa. This study examines these issues in Zambia, analysing data from the International Tobacco Control (ITC) Zambia Survey. Data from Wave 1 of the ITC Zambia Survey (2012) were analysed for current smokers of factory-made (FM) cigarettes compared with those who smoked both FM and roll-your-own (RYO) cigarettes, using multivariate logistic regression models to identify the predictors of brand loyalty and reasons for brand choice. 75% of FM-only smokers and 64% of FM+RYO smokers reported having a regular brand. Compared with FM-only smokers, FM+RYO smokers were, on average, older (28% vs 20% ≥40 years), low income (64% vs 43%) and had lower education (76% vs 44% brands was ZMW0.50 (US$0.08) per stick. Smokers were significantly less likely to be brand loyal (>1 year) if they were aged 15-17 years (vs 40-54 years) and if they had moderate (vs low) income. Brand choice was predicted mostly by friends, taste and brand popularity. Price was more likely to be a reason for brand loyalty among FM+RYO smokers, among ≥55-year-old smokers and among those who reported being more addicted to cigarettes. These results in Zambia document the high levels of brand loyalty in a market where price variation is fairly small across cigarette brands. Future research is needed on longitudinal trends to evaluate the effect of tobacco control policies in Zambia. Published by the BMJ Publishing Group Limited.

    In addition to quitting and cutting consumption, smokers faced with higher cigarette prices may compensate in several ways that mute the health impact of cigarette taxes. This study examines three price avoidance strategies among adult male smokers in Thailand: trading down to a lower-priced brand, buying individual sticks of cigarettes instead of packs, and substituting roll-your-own (RYO) tobacco for factory-manufactured cigarettes. Using two panels of microlevel data from the International Tobacco Control Southeast Asia Study, collected in 2005 and 2006, we estimate the effects of a substantial excise tax increase implemented throughout Thailand in December 2005. We present estimates of the marginal effects and price elasticities for each of five consumer behaviors. We find that, controlling for baseline smoking characteristics, socio-demographics, and policy variables, quitting is highly sensitive to changes in cigarette prices, but so are brand choice, stick-buying, and use of RYO tobacco. Neglecting such strategic responses leads to over-estimates of a sin tax’s health impact, and neglecting product substitution distorts estimates of the price elasticity of cigarette demand. We discuss the implications for consumer welfare and several policies that mitigate the adverse impact of consumer responses. PMID:24677731

    This paper examines how socio-economic status (SES) modifies how smokers adjust to changes in the price of tobacco products through utilization of multiple price minimizing techniques. Data come from the International Tobacco Control Policy Evaluation (ITC) Four Country Survey, nationally representative samples of adult smokers and includes respondents from Canada, the United States, the United Kingdom and Australia. Cross-sectional analyses were completed among 8,243 respondents (7,038 current smokers) from the survey wave conducted between October 2006 and February 2007. Analyses examined predictors of purchasing from low/untaxed sources, using discount cigarettes or roll-your-own (RYO) tobacco, purchasing cigarettes in cartons, and engaging in high levels of price and tax avoidance at last purchase. All analyses tested for interactions with SES and were weighted to account for changing and under-represented demographics. Relatively high levels of price and tax avoidance behaviors were present; 8% reported buying from low or untaxed source; 36% used discount or generic brands, 13.5% used RYO tobacco, 29% reported purchasing cartons, and 63% reported using at least one of these high price avoidance behaviors. Respondents categorized as having low SES were approximately 26% less likely to report using low or untaxed sources and 43% less likely to purchase tobacco by the carton. However, respondents with low SES were 85% more likely to report using discount brands/RYO compared to participants with higher SES. Overall, lower SES smokers were 25% more likely to engage in at least one or more tax avoidance behaviors compared to their higher SES counterparts. Price and tax avoidance behaviors are relatively common among smokers of all SES strata, but strategies differed with higher SES groups more likely to report traveling to a low-tax location to avoid paying higher prices, purchase duty free tobacco, and purchase by cartons instead of packs all of which were less

    Abstract Introduction Raising tobacco prices is the most effective population-level intervention for reducing smoking, but this is undermined by the availability of cheap tobacco. This study monitors trends in cheap tobacco use among adult smokers in the United Kingdom between 2002 and 2014 via changes in product type, purchase source, and prices paid. Methods Weighted data from 10 waves of the International Tobacco Control policy evaluation study were used. This is a longitudinal cohort study of adult smokers with replenishment; 6169 participants provided 15812 responses. Analyses contrasted (1) product type: roll-your-own (RYO) tobacco, factory-made packs (FM-P), and factory-made cartons (FM-C); (2) purchase source: UK store-based sources (e.g., supermarkets and convenience stores) with non-UK/nonstore sources representing tax avoidance/evasion (e.g., outside the UK, duty free, and informal sellers); and (3) prices paid (inflation-adjusted to 2014 values). Generalized estimating equations tested linear changes over time. Results (1) RYO use increased significantly over time as FM decreased. (2) UK store-based sources constituted approximately 80% of purchases over time, with no significant increases in tax avoidance/evasion. (3) Median RYO prices were less than half that of FM, with FM-C cheaper than FM-P. Non-UK/nonstore sources were cheapest. Price increases of all three product types from UK store-based sources from 2002 to 2014 were statistically significant but not substantial. Wide (and increasing for FM-P) price ranges meant each product type could be purchased in 2014 at prices below their 2002 medians from UK store-based sources. Conclusions Options exist driving UK smokers to minimize their tobacco expenditure; smokers do so largely by purchasing cheap tobacco products from UK stores. Implications The effectiveness of price increases as a deterrent to smoking is being undermined by the availability of cheap tobacco such as roll-your-own tobacco and

    In this study, we aimed to examine, in Thailand, the impact on smokers' reported awareness of and their cognitive and behavioral reactions following the change from text-only to pictorial warnings printed on cigarette packs. We also sought to explore differences by type of cigarette smoked (roll-your-own [RYO] vs. factory-made [FM] cigarettes). Data came from the International Tobacco Control Southeast Asia Survey, conducted in Thailand and Malaysia, where a representative sample of 2,000 adult smokers from each country were recruited and followed up. We analyzed data from one wave before (Wave 1) and two waves after the implementation of the new pictorial warnings (two sets introduced at Waves 2 and 3, respectively) in Thailand, with Malaysia, having text-only warnings, serving as a control. Following the warning label change in Thailand, smokers' reported awareness and their cognitive and behavioral reactions increased markedly, with the cognitive and behavioral effects sustained at the next follow-up. By contrast, no significant change was observed in Malaysia over the same period. Compared to smokers who smoke any FM cigarettes, smokers of only RYO cigarettes reported a lower salience but greater cognitive reactions to the new pictorial warnings. The new Thai pictorial health warning labels have led to a greater impact than the text-only warning labels, and refreshing the pictorial images may have helped sustain effects. This finding provides strong support for introducing pictorial warning labels in low- and middle-income countries, where the benefits may be even greater, given the lower literacy rates and generally lower levels of readily available health information on the risks of smoking.

    We used the observed CO/"2"2"2Rn ratio in the Asian outflows at Minamitorishima (MNM), Yonagunijima (YON), and Ryori (RYO) in the western North Pacific from 2007 to 2011, together with a three-dimensional chemical transport model (STAG), in order to estimate anthropogenic emissions of CO in East Asia. The measurements captured high-frequency synoptic variations of enhanced "2"2"2Rn (ERN) events associated with the long-range transport of continental air masses. "2"2"2Rn and CO showed high correlation during the ERN events observed at MNM and YON in the winter and spring, but not at RYO. The STAG transport model reproduced well the concentrations of observed "2"2"2Rn when forced with a constant and uniform flux density of 1.0 atom cm"-"2 s"-"1, but underestimated the associated enhancement of synoptically variable CO caused by the underestimated flux values in the EDGAR ver. 4.1 emission database used in the model for East Asia. Better estimates for the East Asian emission were derived using a radon tracer method based on the difference in the enhancement ratio of CO/"2"2"2Rn between the observation and the model. The anthropogenic emissions of CO for China, Japan, and Korea were estimated to be 203 Tg CO yr"-"1, 91% of which originated in China. When compared with other estimated emissions of CO, our estimated result showed consistency with those of the inverse method, whereas the emission database of EDGAR was about 45% smaller than our anthropogenic estimation for China.

  17. Calculation of the effective delayed neutron fraction by TRIPOLI-4 code for IPEN/MB-01 research reactor

    The effective delayed neutron fraction βeff is an important reactor physics parameter. Its calculation within the multi-group deterministic transport code can be performed with the aid of adjoint flux weighted integrations. However, in continuous energy Monte Carlo transport code, the adjoint weighted βeff calculation becomes complicated due to the backward treatment of the anisotropy scattering. In TRIPOLI-4 continuous energy Monte Carlo code, the βeff calculation was performed by a two-run method, one run with delayed neutrons and second with only the contribution from prompt fission neutrons. To improve the uncertainty of the βeff two-run calculation for the experimental reactors, two simple and fast one-run methods to estimate the βeff in the continuous energy simulation have been implemented into the TRIPOLI-4 code. First approach is an improved one of the Bretscher's prompt method and second one based on the proposal of Nauchi and Kameyama. In these one-run methods, the prompt and the delayed neutrons are first tagged. Their tracking and statistics are separated performed. The new βeff calculations have been optimized in the power iteration cycles so as to estimate the production of prompt and delayed neutrons from the prompt and delayed neutrons of previous generation. To validate the new βeff calculation by TRIPOLI-4, several benchmarks including fast and thermal systems have been considered. In this paper the recent measurements of βeff in the research reactor IPEN/MB-01 have been benchmarked. The basic components of the βeff and the Keff have been also calculated so as to understand the influences of the cross sections and the delayed neutron yields on the reactor reactivity calculations. Three nuclear data libraries, ENDF/BVI.r4, ENDF/B-VII.0, and JEFF-3.1 were taken into account in this study. (author)

    Effects of antibiotics acting on DNA gyrase, novobiocin and nalidixic acid on RNA synthesis during germination, vegetative growth and sporulation of Bacillus subtilis were examined. These drugs were relatively ineffective in inhibiting RNA synthesis of phase Gm 1 (5-15 min) during germination but effective in those of Gm 2 (15-40 min) and Gm 3 (40-60 min) during germination (Matsuda and Kameyama 1980). No distinguishable inhibitory effects of RNA synthesis in B. subtilis NOVr1TT mutant could be detected by novobiocin. RNA synthesis of Gm 2 and Gm 3 of this mutant was inhibited by nalidixic acid. When novobiocin was added to exponential vegetative cell or sporulating cell culture at T0 and T1 stage, the rate of RNA synthesis was inhibited by 80% for 5 min following addition of the drug. However, RNA synthesis after T2 of sporulation became resistant toward novobiocin, as was the case at an early stage of germination. RNA profiles from transcripts synthesized on administration of NOV suggested that the suppression of the synthesis of 23S and 16S rRNA is relatively greater than 4 to 5S RNA at the middle stage of germination and at vegetative growth stage in the presence of NOV. Our present data suggest that DNA gyrase is involved in the regulation of gene transcription during middle and late phases of germination, vegetative growth and T0 and T1 of sporulation. The transcription during early phase of germination and sporulation after T2 may proceed independently of this enzyme.

    To study the auditory impairment induced by prenatal administration of aminoglycosides in the offspring, the shuttle box method to measure the auditory threshold of rats (Kameyama et al., Folia pharmacol. japon. 77, 15, 1981) was employed. Four groups of pregnant rats were administered 200 mg/kg kanamycin sulfate (KM), 200 mg/kg dihydrostreptomycin sulfate (DHSM), 100 mg/kg neomycin sulfate (NM), or 1 ml/kg saline intramuscularly from the 10th to the 19th day of pregnancy. The auditory threshold of the offspring could be measured by the shuttle box method in about 90% of the live born rats at the age of 100 days. The auditory thresholds of the groups were as follows (mean +/- S.E.): saline group, 53.8 +/- 0.6 dB (N = 36); KM group, 63.8 +/- 1.1 dB (N = 34); DHSM group, 60.0 +/- 1.2 dB (N = 29); NM group, 62.4 +/- 1.2 dB (N = 24). Auditory thresholds of drug-treated groups were significantly higher than that of the saline group. However, no increase in the auditory threshold of the mother rat was detected after treatment with aminoglycosides. In addition, the experimental procedure of the shuttle box method is very easy, and the auditory threshold of a large number of rats could be measured in a short period. These findings suggest that this method is a very useful one for screening for auditory impairment induced by prenatal drug treatment in rat offspring.

    Full Text Available Abstract Background Many smokers believe that "light" cigarettes are less harmful than regular cigarettes, which is at variance with the scientific evidence. The Framework Convention on Tobacco Control (FCTC aims to address this problem in Article 11 which deals with misleading labelling of tobacco products. In this study we aimed to determine smokers' use and beliefs concerning "light" and "mild" cigarettes ("lights", including in relation to ethnicity, deprivation and other socio-demographic characteristics. Methods The New Zealand (NZ arm of the International Tobacco Control Policy Evaluation Survey (ITC Project uses as its sampling frame the NZ Health Survey. This is a national sample with boosted sampling of Maori, Pacific peoples and Asians. From this sample we surveyed adult smokers (n = 1376 about use and beliefs relating to "light" cigarettes. We assessed the associations with smoking "lights" after adjusting for socio-demographic variables, and smoking-related behaviours and beliefs. Results Many smokers of "lights" believed that smoking "lights" made it easier to quit smoking (25%, that "lights" are less harmful (42%, and that smokers of "lights" take in less tar (43%. Overall most "lights" smokers (60% had at least one of these three beliefs, a proportion significantly higher than for smokers of "regular" cigarettes at 45% (adjusted odds ratio (aOR = 1.96, 95% CI = 1.29 – 2.96. While "lights" smokers had significantly lower tobacco consumption and were more aware of smoking harms, they were no more likely to be intending to quit or have made a previous quit attempt. By ethnicity, both Maori and Pacific people were less likely to smoke "lights" than Europeans (aOR = 0.53, 95% CI = 0.35 – 0.80 and aOR = 0.14, 95% CI = 0.05 – 0.40 respectively. In contrast there was no significant difference by level of deprivation. Roll-your-own (RYO tobacco smokers were less likely to smoke "light" forms of RYO tobacco while both older and women

    To describe changes among smokers in use of various types of tobacco products, reported prices paid and cigarette consumption following the standardisation of tobacco packaging in Australia. National cross-sectional telephone surveys of adult smokers were conducted from April 2012 (6 months before transition to plain packaging (PP)) to March 2014 (15 months afterwards). Multivariable logistic regression assessed changes in products, brands and pack types/sizes; multivariable linear regression examined changes in inflation-adjusted prices paid and reported cigarette consumption between the pre-PP and three subsequent periods-the transition phase, PP year 1 and PP post-tax (post a 12.5% tax increase in December 2013). The proportion of current smokers using roll-your-own (RYO) products fluctuated over the study period. Proportions using value brands of factory-made (FM) cigarettes increased from pre-PP (21.4%) to PP year 1 (25.5%; p=0.002) and PP post-tax (27.8%; pIntroduction of PP was associated with an increase in use of value brands, likely due to increased numbers available and smaller increases in prices for value relative to premium brands. Reported consumption declined following the December 2013 tax increase. Published by the BMJ Publishing Group Limited.

Furthermore, the chemistry of microporous hydroxyapatite and zirconia were tested to determine which of these two ceramics are most suitable for guided bone generation. 24 hollow domes in two different ceramic materials were placed subperiosteal on rabbit skull bone. The rabbits were sacrificed after 12 weeks and the histology results were analyzed regarding bone-to-material contact and volume of newly formed bone. The results suggest that the effect of the microporous structure of hydroxyapatite seems to facilitate for the bone cells to adhere to the material and that zirconia enhance a slightly larger volume of newly formed bone. In conclusion, the results of the current study demonstrated that ceramic space maintaining devices permits new bone formation and osteoconduction within the dome.

    Ryo et al (2005 Diabetes Care 28 451–3) reported a new method for measuring the visceral fat area (VFA) by combining abdominal bioelectrical impedance analysis (BIA) with measurement of waist circumference (WC), but very few methodological details were provided. Furthermore, the study did not test the use of WC alone as an indicator of VFA even though others had previously reported a strong correlation. We sought to determine the optimal measurement technique and analysis for measuring VFA by abdominal BIA and WC. 18 volunteers (age 23–64 years) underwent measurement of WC, abdominal impedance (Bodystat 500 four-electrode system) and a single cross-sectional CT scan at the umbilicus. VFA derived using WC 3 and measurements of abdominal impedance from electrode pairs sited at the flank predicted the value of VFA measured by CT with correlation r = 0.904 (p 1.9 alone, without involving BIA at all, provided a similar correlation (r = 0.923). Our small preliminary study shows that abdominal BIA is potentially a practicable non-invasive technique for measurement of VFA but casts doubt on whether it adds any value to the use of WC alone. Larger studies are now required to test this finding. (note)

Therefore, application of sunscreen is recommended for the prevention of photoaging in many countries. However, the relationship between UV exposure and photoaging has rarely been investigated in clinical studies in Japan. In addition, there have been almost no long-term interventional studies in Japanese people. We have previously conducted a study where Japanese actinic keratosis patients were instructed to continuously apply sunscreen. The results indicated that long-term application of sunscreen is effective in suppressing actinic keratosis progression and generation. In the present study, we investigated the effects of sunscreen on photoaged skin in 14 elderly Japanese people. Skin conditions such as water content, transepidermal water loss, the number of spots, wrinkles, and skin color tone uniformity were measured and compared before and after the study. A statistically significant difference was observed only in skin surface hydration. There were large inter-individual differences in amount of sunscreen used throughout the study. The changes in the number of spots and skin color tone uniformity during the 18 months showed good correlation with amount of sunscreen being used. These results suggest an increase in the number of spots and deterioration in skin color tone uniformity in the 18-month non-sunscreen application period, and that such skin conditions improved with increasing use of sunscreen. In this study, we suggested

Recently, we revealed that folate-appended methyl-β-cyclodextrin (FA-M-β-CyD provides selective antitumor activity in folate receptor-α (FR-α-expressing cells by the induction of autophagy. In this study, to gain insight into the detailed mechanism of this antitumor activity, we focused on the induction of mitophagy by the treatment of FR-α-expressing tumor cells with FA-M-β-CyD. In contrast to methyl-β-cyclodextrin, FA-M-β-CyD entered KB cells, human epithelial cells from a fatal cervical carcinoma (FR-α (+ through FR-α-mediated endocytosis. The transmembrane potential of isolated mitochondria after treatment with FA-M-β-CyD was significantly elevated. In addition, FA-M-β-CyD lowered adenosine triphosphate (ATP production and promoted reactive oxygen species production in KB cells (FR-α (+. Importantly, FA-M-β-CyD enhanced light chain 3 (LC3 conversion (LC3-I to LC3-II in KB cells (FR-α (+ and induced PTEN-induced putative kinase 1 (PINK1 protein expression, which is involved in the induction of mitophagy. Furthermore, FA-M-β-CyD had potent antitumor activity in BALB/c nu/nu mice xenografted with KB cells (FR-α (+ without any significant side effects. Taken together, these findings demonstrate that the autophagic cell death elicited by FA-M-β-CyD could be associated with mitophagy induced by an impaired mitochondrial function.

    Full Text Available We introduce a new visualization method for the three dimensional data with laser scanning from helicopter to express of the detailed landscape with "Red Relief Image Map (RRIM"and "3D-Viewer". This RRIM and 3D-Viewer’s method effectively represent 3D topographic information without any additional devices and stereopsis ability for the audience only through two dimensional medium and shows an appropriate form of every feature in the site. Chapters present what the laser scanning from helicopter is and show some examples of mounded tombs with RRIM and 3D-Viewer. This visualization technique including detailed topographical information and geographical coordinates can be directly linked to CAD and GIS system, therefore the LiDAR can easily produce a contour line, a cross section and a bird's-eye view at any place as well as measure the height of trees. This is different from other 3D topographic image with a shadow effect. Vegetation on the site is no longer obstacle to get detailed topographical information. Therefore, in Japan, this method is useful for huge mounded tombs thickly covered with trees, especially "Ryo-bo (imperial tomb"which are administrated by the Imperial Household Agency and common people can't enter. Also a cluster of small mounded tombs which extend in the vast area called "Gunshufun" is shown effectively for the location of each mounded tomb. This method is suitable for understanding the structure of the sites in any wide spread archaeological fields. Moreover, in the management of heritages it is important that these data present precise information of the surface of lands to understand the present situation of heritages. Detailed topographical information by "LiDAR and Red Relief Image Map and 3DViewer" will open a new gate for managing of cultural heritage sites in the future.

    Full Text Available Background In Turkey, adoption and implementation of MPOWER strategies were accompanied by a neoliberal tobacco policy framework aiming at supply-side growth, initiated in 1980's and culminating in Law No 4733 in 2002, which solidified liberalization, privatization, and market efficiency rules for tobacco manufacturing and trade, and guaranteed oligopoly conditions for transnational tobacco companies (TTCs. This study employs empirical market dynamics data to argue that demand reduction strategies cannot be pursued effectively in tandem with neoliberal policies. Methods Legal market dynamics are gauged with official data (2003-2016 on licenced tobacco products. The magnitude of illicit product market is assessed by employing prevalence data and estimations in secondary sources. Results During 2003-2016, (a Manufacturing and exports of licenced products have risen sharply (Cigarette manufacturing by 3 billion sticks/year; 2 new cigarette brands licenced per month. The declining trend in legal cigarette sales since 1999 was disrupted during last 5 years and was pushed upward. (b In addition to illicit cigarettes (market share 7.5%, the staggering growth in illicit RYO tobacco, estimated at 15,000 tonnes for 2016 by Tobacco Experts Association, represents 20.5 billion cigarette equivalents, which explains legal sales of 19 billion macarons (empty cigarette tubes in 2016. Estimated share of illicit products in total consumption has thus reached unprecedented level of 27%. Furthermore, using prevalence data, WPT market is estimated as 99% illicit. Conclusions Both legal and illicit tobacco product markets are growing in Turkey, indicating neoliberal framework has had far larger de facto impact than demand reduction efforts, and Law No 4733 is failing, given emergent duality between legal and illicit markets epitomised by TTCs and domestic outfits, respectively. This picture is in clear defiance of FCTC objectives, principles, and obligations, and

    Full Text Available Ryo Rokutanda, Mitsumasa Kishimoto, Masato Okada Immuno-Rheumatology Center, St Luke’s International Hospital, Tokyo, Japan Abstract: Behçet’s disease is a multi-organ disorder that is more common in countries around the Silk Road, and manifests as mucosal ulcers and skin lesions, and with ocular involvement. As a systemic disease, it can also involve gastrointestinal organs and the central nervous or cardiovascular systems. Although the etiology of Behçet's disease is not clearly identified, the pathogenesis of the disease is most commonly hypothesized as a profound inflammatory response triggered by an infectious agent in a genetically susceptible host. As there are no single specific manifestations or specific diagnostic tests, various diagnostic criteria have been proposed around the world, and, among them, the International Study Group criteria have been most commonly used. As the clinical expression of Behçet's disease is heterogeneous, the treatment should be individualized based on involved organs, severity of the disease, and patient's background. The choice of therapeutic agents is limited by lack of clinical trials and is based largely on case reports, case series, and several open-label clinical trials. Corticosteroids, colchicine, and traditional immunosuppressive agents, including azathioprine and cyclosporine, have been used for the treatment of Behçet’s disease. Recently, tumor necrosis factor (TNF inhibitors have become available for several rheumatic diseases, and considerable published data suggest that TNF inhibitors represent an important therapeutic advance for patients with severe and resistant disease, as well as for those with contraindications or intolerance to these treatments.

    Full Text Available This paper describes the modification of an existing gas chromatographic (GC method to incorporate simultaneous mass spectrometric (MSD and flame ionization detection (FID into the analysis of tobacco humectants. Glycerol, propylene glycol, and triethylene glycol were analyzed in tobacco labeled as roll-your-own (RYO, cigar, cigarette, moist snuff, and hookah tobacco. Tobacco was extracted in methanol containing 1,3-butanediol (internal standard, filtered, and separated on a 15 m megabore DB-Wax column. Post-column flow was distributed using a microfluidic splitter between the MSD and FID for simultaneous detection. The limits of detection for the FID detector were 0.5 μg/mL (propylene glycol and triethylene glycol and 0.25 μg/mL (glycerol with a linear range of 2-2000 μg/mL (propylene glycol and triethylene glycol and 1-4000 μg/mL (glycerol. The limits of detection for the MSD detector were 2 μg/mL (propylene glycol and triethylene glycol and 4 μg/mL (glycerol with a linear range of 20-2000 μg/mL (propylene glycol and triethylene glycol and 40-4000 μg/mL (glycerol. Significant improvement in the sensitivity of the MSD can be achieved by employing selective ion monitoring (SIM detection mode. Although a high degree of correlation was observed between the results from FID and MSD analyses, marginal chromatographic resolution between glycerol and triethylene glycol limits the applicability of FID to samples containing low levels of both of these humectants. Utilizing MSD greatly improves the reliability of quantitative results because compensation for inadequate chromatographic resolution can be accomplished with mass selectivity in detection.

However, the deficient osteogenic properties and the bioinertness of PEEK limit its fields of application. The aim of this study was to limit these drawbacks by coating the surface of PEEK with nano-scaled hydroxyapatite (HA minerals. In the study, the biological response to PEEK, with and without HA coating, was investigated. Twenty-four screw-like and apically perforated implants in the rabbit femur were histologically evaluated at 3 weeks and 12 weeks after surgery. Twelve of the 24 implants were HA coated (test, and the remaining 12 served as uncoated PEEK controls. At 3 weeks and 12 weeks, the mean bone–implant contact was higher for test compared to control (P<0.05. The bone area inside the threads was comparable in the two groups, but the perforating hole showed more bone area for the HA-coated implants at both healing points (P<0.01. With these results, we conclude that nano-sized HA coating on PEEK implants significantly improved the osteogenic properties, and in a clinical situation this material composition may serve as an implant where a rapid bone fusion is essential.

Other roles of FGF23 have recently been reported, such as commitment to myocardium enlargement and immunological roles in the spleen. In this study, we aimed to identify the roles of FGF23 in the kidneys other than calcium–phosphorus metabolism. Methods: DNA microarrays and bioinformatics tools were used to analyze gene expression in mIMCD3 mouse renal tubule cells following treatment with FGF23, erythropoietin and/or an inhibitor of ERK. Results: Three protein-coding genes were upregulated and 12 were downregulated in response to FGF23. Following bioinformatics analysis of these genes, PPARγ and STAT3 were identified as candidate transcript factors for mediating their upregulation, and STAT1 as a candidate for mediating their downregulation. Because STAT1 and STAT3 also mediate erythropoietin signaling, we investigated whether FGF23 and erythropoietin might show interactive effects in these cells. Of the 15 genes regulated by FGF23, 11 were upregulated by erythropoietin; 10 of these were downregulated following cotreatment with FGF23. Inhibition of ERK, an intracellular mediator of FGF23, reversed the effects of FGF23. However, FGF23 did not influence STAT1 phosphorylation, suggesting that it impinges on erythropoietin signaling through other mechanisms. Conclusion: Our results suggest cross talk between erythropoietin and FGF23 signaling in the regulation of renal epithelial cells. Keywords: FGF23, STAT1, PPARγ, DNA microarray

Nine patients, comprising of five males and four females, showing large and myopic MHs, underwent pars plana vitrectomy (PPV with inverted ILM flap technique assisted by brilliant blue G (BBG staining. Ophthalmological findings including visual acuity and OCT were investigated based on medical records. Formalin-fixed paraffin-embedded tissue section of an ILM-like membrane was submitted for immunohistochemistry with glial fibrillary acidic protein (GFAP.Results: ILM was clearly stained with BBG in eight patients, whereas the ILM in one case revealed no staining with BBG during PPV. Visual acuities improved to >0.2 LogMAR in six patients. The complete closure of MH following PPV with inverted ILM technique was eventually achieved in all patients determined by OCT imaging (100%. Only one patient showed recovery of ellipsoid zone and interdigitation zone following the surgery. Elongation of outer nuclear layer was noted in three eyes. The ILM-like membrane not stained with BBG histologically revealed an amorphous structure admixed with GFAP-positive mononuclear cell infiltration.Conclusion: PPV with inverted ILM flap technique achieved 100% closure rates with favorable configuration at an initial surgery in large MHs. Our histopathological data also suggest that even BBG staining-negative membrane may be a useful material for autologous transplantation to the hole. Keywords

The aim of this study was to provide evidence that ETS exposure from the husband at home has a more significant influence on the airway obstruction of nonsmoking women than other housemates. Participants and methods: Nonsmoking women aged 40 years or older were recruited from the health checkup during May 2015–December 2016, Japan. They answered structured questionnaires, including ETS exposure from their husbands and other housemates (parents, siblings and dependants, and performed spirometry. We categorized the women with any history of ETS exposure from housemates into three groups (A = husband, B = others and C = both of husband and others and defined the control group as those with no ETS exposure from housemates. Results: A total of 811 nonsmoking women completed questionnaires and spirometry. The proportion of nonsmoking women who had airway obstruction (forced expiratory volume in 1 second [FEV1]/forced vital capacity [FVC] <70% among Group A (7.5% was significantly higher than those in the control group (1.1%, p<0.01 and Group B (0.8%, p<0.01.

In previous studies, the primary method for obtaining data stored in a database is to extract drug information from package inserts by employing pattern matching or more sophisticated methods such as text mining. However, it is difficult to obtain a complete database because there is no strict rule concerning expressions used to describe drug information in package inserts. The authors' strategy was to first build a database and then automatically generate package inserts by embedding data in the database using templates. To create this database, the support of pharmaceutical companies to input accurate data is required. It is expected that this system will work, because these companies can earn merit for newly developed drugs to decrease the effort to create package inserts from scratch. This study designed the table schemata for the database and text templates to generate the package inserts. To handle the variety of drug-specific information in the package inserts, this information in drug composition descriptions was replaced with labels and the replacement descriptions utilizing cluster analysis were analyzed. To improve the method by which frequently repeated ingredient information and/or supplementary information are stored, the method was modified by introducing repeat tags in the templates to indicate repetition and improving the insertion of data into the database. The validity of this method was confirmed by inputting the drug information described in existing package inserts and checking that the method could

Therefore, the management of side effects is essential for the longer period of continuous medication. Among the various side effects, hand–foot syndrome (HFS is the most common, occurring in 30%–50% of patients, and often results in discontinuation of the SOR medication. However, its mechanism has not been clarified, and no effective prevention method has been reported for the symptoms. Therefore, this study aimed to analyze its mechanism and to develop an effective prevention regimen for the symptoms. Materials and methods: To assess the mechanism of SOR-induced HFS, the peripheral blood flow in the hand and foot was carefully monitored by Doppler ultrasound, thermography, and laser speckle flowgraphy in the cases treated with SOR and its contribution was assessed. Then, the effect of dried-bonito broth (DBB, which was reported to improve peripheral blood flow, on the prevention of the symptom was

In order to improve adherence by providing information about AD and the significance of pharmacotherapy, the Donepezil Outpatient Consultation Service (DOCS was set up. The influence of this service on medication persistence was assessed in the present study.Methods: Among outpatients starting donepezil therapy, we enrolled 59 patients between April 2008 and September 2010 before establishment of the DOCS (non-DOCS group and 52 patients between October 2010 and March 2012 who attended the DOCS (DOCS group. Each patient's and their caregiver's understanding about the clinical features of AD and pharmacotherapy with donepezil were also assessed. Their understanding was compared before and after the DOCS, and the 1-year medication persistence rate and the reasons for discontinuation were also investigated.Results: The 1-year medication persistence rate was significantly higher in the DOCS group than in the non-DOCS group (73
