    There is a growing evidence of an ecological association between alcohol outlet density and intimate partner violence. It is reasonable to assume, however, that not all types of alcohol outlets contribute equally to criminal behavior, and to date, most ecological studies have been of large urban cities. Using Bloomington, Indiana, block groups as units of analysis and controlling for several structural characteristics associated with violence rates, I estimated spatially lagged regression models to determine if the variation in alcohol outlet density, including total outlets and disaggregating by on- and off-premise outlets, is related to intimate partner violence density. Results suggested that total alcohol outlet density and off-premise alcohol outlet density were significantly associated with intimate partner violence density. On-premise alcohol outlet density was not significantly associated with intimate partner violence density. These results not only extend the geographic scope of this relationship beyond large metropolitan areas but also have important policy implications.

    Full Text Available OBJECTIVES: The current study set out to investigate alcohol availability in a densely populated, residential area of suburban São Paulo associated with high levels of social deprivation and violence. Gun-related deaths and a heavy concentration of alcohol outlets are notable features of the area surveyed. Given the strong evidence for a link between alcohol availability and a number of alcohol-related problems, including violent crime, measures designed to reduce accessibility have become a favored choice for alcohol prevention programs in recent years. METHODS: The interviewers were 24 residents of the area who were trained for the study. It was selected an area of nineteen streets, covering a total distance of 3.7 km. A profile of each alcohol outlet available on the area was recorded. RESULTS: One hundred and seven alcohol outlets were recorded. The number of other properties in the same area was counted at 1,202. Two measures of outlet density may thus be calculated: the number of outlets per kilometer of roadway (29 outlets/km; and the proportion of all properties that sold alcohol (1 in 12. CONCLUSIONS: The results of this study is compared with others which are mainly from developed countries and shown that the area studied have the highest density of alcohol outlet density ever recorded in the medical literature. The implication of this data related to the violence of the region is discussed. By generating a profile of alcohol sales and selling points, it was hoped to gain a better understanding of alcohol access issues within the sample area. Future alcohol prevention policy would be well served by such knowledge.

    Full Text Available The objective of this study was to assess the relationship between alcohol availability, as measured by the density of off-premise alcohol outlets, and alcohol consumption in Los Angeles county and southern Louisiana, USA. Consumption information was collected through a telephone survey of 2,881 households in Los Angeles county and pre-Katrina southern Louisiana, nested within 220 census tracts. Respondents’ addresses were geo-coded and both neighbourhood (census tracts and buffers of varying sizes and individual (network distance to the closest alcohol outlet estimates of off-sale alcohol outlet density were computed. Alcohol outlet density was not associated with the percentage of people who were drinkers in either site. Alcohol outlet density was associated with the quantity of consumption among drinkers in Louisiana but not in Los Angeles. Outlet density within a one-mile buffer of the respondent’s home was more strongly associated with alcohol consumption than outlet density in the respondent’s census tract. The conclusion is that the relationship between neighbourhood alcohol outlet density and alcohol consumption is complex and may vary due to differences in neighbourhood design and travel patterns.

    There is growing evidence from multiple disciplines that alcohol outlet density is associated with community levels of assault. Based on the theoretical and empirical literatures on social organization and crime, we tested the hypothesis that the association between alcohol outlet density and neighbourhood violence rates is moderated by social organization. Using geocoded police data on assaults, geocoded data on the location of alcohol outlets, and controlling for several structural factors thought to be associated with violence rates, we tested this hypothesis employing negative binomial regression with our sample of 298 block groups in Cincinnati. Our results revealed direct effects of alcohol outlet density and social organization on assault density, and these effects held for different outlet types (i.e., off-premise, bars, restaurants) and levels of harm (i.e., simple and aggravated assaults). More importantly, we found that the strength of the outlet-assault association was significantly weaker in more socially organized communities. Subsequent analyses by level of organization revealed no effects of alcohol outlet density on aggravated assaults in organized block groups, but significant effects in disorganized block groups. We found no association between social (dis)organization and outlet density. These results clarify the community-level relationship between alcohol outlets and violence and have important implications for municipal-level alcohol policies.

    Full Text Available Abstract Background Excess alcohol consumption has serious adverse effects on health and violence-related harm. In the UK around 37% of men and 29% of women drink to excess and 20% and 13% report binge drinking. The potential impact on population health from a reduction in consumption is considerable. One proposed method to reduce consumption is to reduce availability through controls on alcohol outlet density. In this study we investigate the impact of a change in the density of alcohol outlets on alcohol consumption and alcohol-related harms to health in the community. Methods/Design A natural experiment of the effect of change in outlet density between 2005–09, in Wales, UK; population 2.4 million aged 16 years and over. Data on outlets are held by the 22 local authorities in Wales under The Licensing Act 2003. The study outcomes are change in (1 alcohol consumption using data from annual Welsh Health Surveys, (2 alcohol-related hospital admissions using the Patient Episode Database for Wales, (3 Accident & Emergency department attendances between midnight–6am, and (4 alcohol-related violent crime against the person, using Police data. The data will be anonymously record-linked within the Secure Anonymised Information Linkage Databank at individual and 2001 Census Lower Super Output Area levels. New methods of network analysis will be used to estimate outlet density. Longitudinal statistical analysis will use (1 multilevel ordinal models of consumption and logistic models of admissions and Accident & Emergency attendance as a function of change in individual outlet exposure, adjusting for confounding variables, and (2 spatial models of the change in counts/rates of each outcome measure and outlet density. We will assess the impact on health inequalities and will correct for population migration. Discussion This inter-disciplinary study requires expertise in epidemiology and public health, health informatics, medical statistics

    Excessive alcohol use causes approximately 80,000 deaths in the United States each year. The Guide to Community Preventive Services recommends reducing the density of alcohol outlets - the number of physical locations in which alcoholic beverages are available for purchase either per area or per population - through the use of regulatory authority as an effective strategy for reducing excessive alcohol consumption and related harms. We briefly review the research on density of alcohol outlets and public health and describe the powers localities have to influence alcohol outlet density. We summarize Regulating Alcohol Outlet Density: An Action Guide, which describes steps that local communities can take to reduce outlet density and the key competencies and resources of state and local health departments. These include expertise in public health surveillance and evaluation methods, identification and tracking of outcome measures, geographic information systems (GIS) mapping, community planning and development of multisector efforts, and education of community leaders and policy makers. We illustrate the potential for partnerships between public health agencies and local communities by presenting a contemporary case study from Omaha, Nebraska. Public health agencies have a vital and necessary role to play in efforts to reduce alcohol outlet density. They are often unaware of the potential of this strategy and have strong potential partners in the thousands of community coalitions nationwide that are focused on reducing alcohol-related problems.

  8. The ecology of domestic violence: the role of alcohol outlet density

    Full Text Available Studies have consistently found positive associations between the density of alcohol outlets and levels of violence in areas. Few studies have examined whether this relationship holds for domestic violence. This study assesses whether alcohol outlet density is related to domestic violence and whether this relationship is due to alcohol availability or to co-occurring economic disadvantage and social disorganisation. Cross-sectional data on family incidents, liquor outlets and socio-demographic characteristics were obtained for 217 postcodes in Melbourne, Australia. These data were used to construct models assessing the association between alcohol outlet density and domestic violence, both with and without controlling for socio-demographic factors. Models were tested for spatial autocorrelation, and spatial- error models were developed to control for its influence. Outlet density was significantly associated with rates of domestic violence, even controlling for socio-demographic factors. The density of hotels (pubs was positively associated with domestic violence rates and the density of restaurants and bars was negatively associated with domestic violence. Socio-economic disadvantage was also associated with domestic violence rates. The density of packaged liquor outlets was not associated with rates of domestic violence. The results present a mixed picture, and further study is required to develop a clearer understanding of the links between alcohol availability and domestic violence.

    Some states maintain high-quality alcohol outlet databases but quality varies by state, making comprehensive comparative analysis across US communities difficult. This study assesses the adequacy of using ZIP Code Business Patterns (ZIP-BP) data on establishments as estimates of the number of alcohol outlets by ZIP code. Specifically we compare ZIP-BP alcohol outlet counts with high-quality data from state and local records surrounding 44 college campus communities across 10 states plus the District of Columbia. Results show that a composite measure is strongly correlated (R=0.89) with counts of alcohol outlets generated from official state records. Analyses based on Generalized Estimation Equation models show that community and contextual factors have little impact on the concordance between the two data sources. There are also minimal inter-state differences in the level of agreement. To validate the use of a convenient secondary data set (ZIP-BP) it is important to have a high correlation with the more complex, high quality and more costly data product (i.e., datasets based on the acquisition and geocoding of state and local records) and then to clearly demonstrate that the discrepancy between the two to be unrelated to relevant explanatory variables. Thus our overall findings support the adequacy of using a conveniently available data set (ZIP-BP data) to estimate alcohol outlet densities in ZIP code areas in future research.

    This study investigates the relationship between concentrations of on- and off-premises alcohol outlets and rates of child abuse and neglect. Additionally, the study seeks to locate protective features of a neighborhood's built environment by investigating the potentially moderating role that access to substance abuse treatment and prevention services plays in the relationship between alcohol outlet density and child maltreatment. Using a cross-sectional design, this ecological study utilized data from 163 census tracts in Bergen County, New Jersey, on reports of child abuse and neglect, alcohol outlets, substance abuse treatment and prevention facilities, and the United States Census to investigate the linkages between socioeconomic structure, alcohol availability, and access to substance abuse service facilities on rates of child abuse and neglect. Findings indicate areas with a greater concentration of on-premises alcohol outlets (i.e., bars) had higher rates of child neglect, and those with easier access to substance abuse services had lower rates of neglect, controlling for neighborhood demographic and socioeconomic structure. Additionally, the relationship between on-premises alcohol outlet density and rates of child neglect was moderated by the presence of substance abuse service facilities. A greater concentration of off-premises outlets (i.e., liquor stores) was associated with lower rates of physical abuse. Findings suggest that the built environment and socioeconomic structure of neighborhoods have important consequences for child well-being. The implications for future research on the structural features of neighborhoods that are associated with child well-being are discussed.

    Full Text Available Abstract Background Alcohol related violence continues to be a major public health problem in the United States. In particular, there is substantial evidence of an association between alcohol outlets and assault. However, because the specific geographic relationships between alcohol outlets and the distribution of violence remains obscured, it is important to identify the spatial linkages that may exist, enhancing public health efforts to curb both violence and morbidity. Methods The present study utilizes police-recorded data on simple and aggravated assaults in Cincinnati, Ohio. Addresses of alcohol outlets for Cincinnati, including all bars, alcohol-serving restaurants, and off-premise liquor and convenience stores were obtained from the Ohio Division of Liquor Control and geocoded for analysis. A combination of proximity analysis, spatial cluster detection approaches and a geographic information system were used to identify clusters of alcohol outlets and the distribution of violence around them. Results A brief review of the empirical work relating to alcohol outlet density and violence is provided, noting that the majority of this literature is cross-sectional and ecological in nature, yielding a somewhat haphazard and aggregate view of how outlet type(s and neighborhood characteristics like social organization and land use are related to assaultive violence. The results of the statistical analysis for Cincinnati suggest that while alcohol outlets are not problematic per se, assaultive violence has a propensity to cluster around agglomerations of alcohol outlets. This spatial relationship varies by distance and is also related to the characteristics of the alcohol outlet agglomeration. Specifically, spatially dense distributions of outlets appear to be more prone to clusters of assaultive violence when compared to agglomerations with a lower density of outlets. Conclusion With a more thorough understanding of the spatial relationships

    Full Text Available Objective: Alcohol is more likely than any other drug to be involved in substance-related violence. In 2000 violence-related and self-directed injuries accounted for an estimated $37 billion and $33 billion in productivity losses and medical treatment, respectively. A review of emergency department data revealed violence and clinically identified trauma-related injuries have the strongest correlation among alcohol-dependent injuries. At the environmental level there is a relationship between alcohol outlet density and violent crime. A limited number of studies have examined the relationship between alcohol outlet type and the components of violent crime. The aim of this study is to examine the relationship between the aggregate components of violent crime and alcohol outlet density by type of outlet.Methods: For this study we used Washington, D.C. census tract data from the 2000 census to examine neighborhood characteristics. Alcohol outlet, violent crime, and population-level data for Washington, D.C. were drawn from various official yet publicly available sources. We developed an analytic database to examine the relationship between alcohol outlet category and four types of violent crime. After estimating spatial correlation and determining spatial dependence, we used a negative binomial regression analysis to assess the alcohol availability-violent crime association, while controlling for structural correlates of violence.Results: Independent of alternative structural correlates of violent crime, including the prevalence of weapons and illicit drugs, community-level alcohol outlet density is significantly associated with assaultive violence. Outlets were significantly related to robbery, assault, and sexual offenses. In addition, the relationship among on-premise and off-premise outlets varied across violent crime categories.Conclusion: In Washington, D.C., alcohol outlet density is significantly associated with the violent crimes.

    Although past research has linked alcohol outlet density to higher rates of drinking and many related social problems, there is conflicting evidence of density's association with traffic crashes. An abundance of local alcohol outlets simultaneously encourages drinking and reduces driving distances required to obtain alcohol, leading to an indeterminate expected impact on alcohol-involved crash risk. This study separately investigates the effects of outlet density on (1) the risk of injury crashes relative to population and (2) the likelihood that any given crash is alcohol-involved, as indicated by police reports and single-vehicle nighttime status of crashes. Alcohol outlet density effects are estimated using Bayesian misalignment Poisson analyses of all California ZIP codes over the years 1999-2008. These misalignment models allow panel analysis of ZIP-code data despite frequent redefinition of postal-code boundaries, while also controlling for overdispersion and the effects of spatial autocorrelation. Because models control for overall retail density, estimated alcohol-outlet associations represent the extra effect of retail establishments selling alcohol. The results indicate a number of statistically well-supported associations between retail density and crash behavior, but the implied effects on crash risks are relatively small. Alcohol-serving restaurants have a greater impact on overall crash risks than on the likelihood that those crashes involve alcohol, whereas bars primarily affect the odds that crashes are alcohol-involved. Off-premise outlet density is negatively associated with risks of both crashes and alcohol involvement, while the presence of a tribal casino in a ZIP code is linked to higher odds of police-reported drinking involvement. Alcohol outlets in a given area are found to influence crash risks both locally and in adjacent ZIP codes, and significant spatial autocorrelation also suggests important relationships across geographical units

    Few studies have considered the potential role of the built environment in increasing adolescent substance use. The current study explored the relationship between alcohol outlets, a potential malleable component of the neighborhood environment, and adolescent behavioral outcomes. Specifically, we investigated the relationship between alcohol outlet density, perceived alcohol, tobacco, and marijuana availability (ATOD), perception of substance use as a problem at the school, and self-reported ATOD use. Data come from Maryland Safe and Supportive Schools (MDS3) Initiative, a statewide project focused on measuring and improving school climate. The sample includes 25,308 adolescents from 58 high schools (9th–12th grade) across 12 counties. Multi-level path models indicated a positive relationship between the count of alcohol outlets and perceived availability of ATOD among girls but not boys. Perceived availability was associated with increased ATOD use at both the individual- and school-level, as well as other students’ ATOD use. Findings provide support for the potential role of the built environment in adolescent risk for substance use, particularly among girls. PMID:27574339

    Full Text Available The objective of this study was to investigate residential exposure to alcohol outlets in relation to alcohol consumption and mental health morbidity (anxiety, stress, and depression. This was a cross-sectional study of 6,837 adults obtained from a population representative sample for the period 2006-2009 in Perth, Western Australia. The number of alcohol outlets was ascertained for a 1600 m service area surrounding the residential address. Zero-inflated negative binomial and logistic regression were used to assess associations with total alcohol consumption, harmful alcohol consumption (7-10 drinks containing 10 g of alcohol for men, 5-6 drinks for women and medically diagnosed and hospital contacts (for anxiety, stress, and depression, respectively. The rate ratio for the number of days of harmful consumption of alcohol per month and the number of standard drinks of alcohol consumed per drinking day was 1.06 (95% CI: 1.02, 1.11 and 1.01 (95% CI: 1.00, 1.03 for each additional liquor store within a 1600 m service area, respectively. The odds ratio of hospital contact for anxiety, stress, or depression was 1.56 (95% CI: 0.98, 2.49 for those with a liquor store within the service area compared to those without. We observed strong evidence for a small association between residential exposure to liquor stores and harmful consumption of alcohol, and some support for a moderate-sized effect on hospital contacts for anxiety, stress, and depression.

    Full Text Available Objective: In an attempt to reduce high levels of traffic crashes, a new legislation was approved in Brazil in 2008. This study aimed to assess behavioral change among drivers who had drunk at alcohol outlets (AO after implementation of the law. Method: A three-stage probability sampling survey was conducted in Porto Alegre, state of Rio Grande do Sul, Brazil. Individuals seen leaving AOs after drinking were approached (n=3,018. Selected drivers (n=683 answered a structured interview, were breathalyzed, and had saliva specimens collected for drug screening. Results: Overall, 60.3% (SE 4.5 of drivers reported they did not change their behavior. Among those who reported behavioral changes, most reported drinking less as their main strategy toward safer driving behavior. Variables independently associated with behavior change included having drunk at a high outlet density area (odds ratio [OR] 1.7 [1.1-2.8] and having a favorable opinion about the law (OR 4.3 [2.1-8.9]. Conclusions: Our findings suggest that awareness of the law has not been enough to promote behavioral change. As most drivers had a favorable opinion of the law and this variable was found to be the strongest predictor of behavior change, efforts to better integrate education and enforcement seem to be pivotal and might be well received by the population.

    Violent crime such as homicide causes significant excess morbidity and mortality in US urban areas. A health impact assessment (HIA) identified zoning policy related to alcohol outlets as one way to decrease violent crime. The objectives were to determine the relationship between alcohol outlets including off-premise alcohol outlets and violent crime in one urban area to provide local public health evidence to inform a zoning code rewrite. An ecologic analysis of census tracts in Baltimore City was conducted from 2011 to 2012. The data included violent crimes (n = 51,942) from 2006 to 2010, licensed alcohol outlets establishments (n = 1,327) from 2005 to 2006, and data on neighborhood disadvantage, percent minority, percent occupancy, and drug arrests from 2005 to 2009. Negative binomial regression models were used to determine the relationship between the counts of alcohol outlets and violent crimes controlling for other factors. Spatial correlation was assessed and regression inference adjusted accordingly. Each one-unit increase in the number of alcohol outlets was associated with a 2.2 % increase in the count of violent crimes adjusting for neighborhood disadvantage, percent minority, percent occupancy, drug arrests, and spatial dependence (IRR = 1.022, 95 % CI = 1.015, 1.028). Off-premise alcohol outlets were significantly associated with violent crime in the adjusted model (IRR = 1.048, 95 % CI = 1.035, 1.061). Generating Baltimore-specific estimates of the relationship between alcohol outlets and violent crime has been central to supporting the incorporation of alcohol outlet policies in the zoning code rewrite being conducted in Baltimore City.

    The purpose of this study is to examine how parental drinking behavior, drinking locations, alcohol outlet density, and types of social support (tangible, emotional, and social companionship) may place children at greater risk for physical abuse. Data on use of physical abuse, drinking behaviors, types of social support, social networks, and demographic information were collected via telephone interviews with 3,023 parent respondents in 50 cities in California. Data on alcohol outlet density were obtained by the California Department of Alcoholic Beverage Control. Multilevel Poisson models were used to analyze data for the drinking levels in the entire sample and dose-response drinking models for drinkers. Social companionship support was related to more frequent use of physical abuse. Having a higher percentage of social companionship support network living within the neighborhood was related to more frequent physical abuse in the full sample. This relationship was moderated by on-premise alcohol outlet density. With regards to drinking behaviors, drinking behaviors from ex-drinkers to frequent heavy drinkers used physically abusive parenting practices more often than lifetime abstainers. The dose-response models show that each additional drinking event at a bar or home/party was related to more frequent use of physical abuse. Practitioners working with parents who abuse their children should be aware that not all social support is beneficial. Findings build evidence that child maltreatment is influenced by the interaction between individual and ecological factors.

  3. The Relationship between Alcohol Outlets, HIV Risk Behavior, and HSV-2 Infection among South African Young Women: A Cross-Sectional Study.

    Full Text Available Alcohol consumption has a disinhibiting effect that may make sexual risk behaviors and disease transmission more likely. The characteristics of alcohol-serving outlets (e.g. music, dim lights, lack of condoms may further encourage risky sexual activity. We hypothesize that frequenting alcohol outlets will be associated with HIV risk.In a sample of 2,533 school-attending young women in rural South Africa, we performed a cross-sectional analysis to examine the association between frequency of alcohol outlet visits in the last six months and four outcomes related to HIV risk: number of sex partners in the last three months, unprotected sex acts in the last three months, transactional sex with most recent partner, and HSV-2 infection. We also tested for interaction by alcohol consumption.Visiting alcohol outlets was associated with having more sex partners [adjusted odds ratio (aOR, one versus zero partners (95% confidence interval (CI: 1.51 (1.21, 1.88], more unprotected sex acts [aOR, one versus zero acts (95% CI: 2.28 (1.52, 3.42], higher levels of transactional sex [aOR (95% CI: 1.63 (1.03, 2.59], and HSV-2 infection [aOR (95% CI: 1.30 (0.88, 1.91]. In combination with exposure to alcohol consumption, visits to alcohol outlets were more strongly associated with all four outcomes than with either risk factor alone. Statistical evidence of interaction between alcohol outlet visits and alcohol consumption was observed for all outcomes except transactional sex.Frequenting alcohol outlets was associated with increased sexual risk in rural South African young women, especially when they consumed alcohol. Sexual health interventions targeted at alcohol outlets may effectively reach adolescents at high risk for sexually transmitted infections like HIV and HSV-2.HIV Prevention Trials Network HPTN 068.

    Investigating the alcohol environment for rural American Indian youth, we conducted 70 interviews with leading members and youth representatives of nine Southern California tribes. We also conducted brief observations in all 13 stores licensed to sell alcohol on and close to the reservation lands of the nine tribes. Underage youth may obtain alcoholic beverages at stores either directly through illegal sales to minors or indirectly through social sources. Stores are also environments within which alcoholic beverages and heavy drinking may become normalized for youth. Limitations and implications for convenience store-based prevention research on alcohol retail environment for youth in rural populations areas are discussed.

    As adolescents gain freedom to explore new environments unsupervised, more time in proximity to alcohol outlets may increase risks for alcohol and marijuana use. This pilot study: 1) Describes variations in adolescents' proximity to outlets by time of day and day of the week, 2) Examines variations in outlet proximity by drinking and marijuana use status, and 3) Tests feasibility of obtaining real-time data to study adolescent proximity to outlets. U.S. adolescents (N = 18) aged 16-17 (50% female) carried GPS-enabled smartphones for one week with their locations tracked. The geographic areas where adolescents spend time, activity spaces, were created by connecting GPS points sequentially and adding spatial buffers around routes. Proximity to outlets was greater during after school and evening hours. Drinkers and marijuana users were in proximity to outlets 1½ to 2 times more than non-users. Findings provide information about where adolescents spend time and times of greatest risk, informing prevention efforts.

    Socioeconomic disparities in the food environment are known to exist but with little understanding of change over time. This study investigated the density of takeaway food outlets and presence of supermarkets in Norfolk, UK between 1990 and 2008. Data on food retail outlet locations were collected from telephone directories and aggregated within electoral wards. Supermarket presence was not associated with area deprivation over time. Takeaway food outlet density increased overall, and was significantly higher in more deprived areas at all time points; furthermore, socioeconomic disparities in takeaway food outlet density increased across the study period. These findings add to existing evidence and help assess the need for environmental interventions to reduce disparities in the prevalence of unhealthy food outlets. PMID:25841285

    Chronic alcohol abuse is associated with low bone density and high risk of fracture. However, moderate alcohol consumption may help to maintain bone density in postmenopausal women by increasing endogenous estrogens or by promoting secretion of calcitonin. We conducted a prospective study among a sample of 188 white postmenopausal women (ages 50-74) from the Nurses' Health Study who participated in a health examination between 1993 and 1995 that included bone density assessments of the lumbar spine and proximal femur. Long-term alcohol intake was calculated as the average of the 1980 and 1990 measures from a food frequency questionnaire. Women who consumed 75 g or more of alcohol per week had significantly higher bone densities at the lumbar spine compared with non-drinking women (0.951 vs. 0.849 g/cm2, p = 0.002) after adjusting for age, body mass index (kg/m2), age at menopause, use of postmenopausal estrogens, and smoking status. Further adjustment for physical activity and daily intakes of calcium, vitamin D, protein, and caffeine did not alter the results. We also observed a linear increase in spinal bone density over increasing categories of alcohol intake (p = 0.002), suggesting that alcohol intakes of less than 75 g/week may also be of benefit. This positive association was observed among both current users and never users of postmenopausal estrogens. In contrast to the lumbar spine, femoral bone density was not higher among drinkers compared with nondrinkers, although density did increase among drinkers with increasing level of alcohol consumption. Further research is needed to determine whether moderate alcohol consumption can help to protect against spinal fractures in postmenopausal women. This finding must also be evaluated within a larger scope of the risks and benefits of alcohol on heart disease, breast cancer, and hip fractures.

    In this paper, we compare and contrast a Bayesian spatially varying coefficient process (SVCP) model with a geographically weighted regression (GWR) model for the estimation of the potentially spatially varying regression effects of alcohol outlets and illegal drug activity on violent crime in Houston, Texas. In addition, we focus on the inherent coefficient shrinkage properties of the Bayesian SVCP model as a way to address increased coefficient variance that follows from collinearity in GWR models. We outline the advantages of the Bayesian model in terms of reducing inflated coefficient variance, enhanced model flexibility, and more formal measuring of model uncertainty for prediction. We find spatially varying effects for alcohol outlets and drug violations, but the amount of variation depends on the type of model used. For the Bayesian model, this variation is controllable through the amount of prior influence placed on the variance of the coefficients. For example, the spatial pattern of coefficients is similar for the GWR and Bayesian models when a relatively large prior variance is used in the Bayesian model.

    Full Text Available Osteoporosis and osteopenia are alterations in bone mineral density (BMD that frequently occur in the context of chronic liver disease (CLD. These alterations have been studied predominantly in chronic cholestatic disease and cirrhosis of the liver. Alcohol consumption is an independent risk factor for the onset of osteoporosis, whose estimated prevalence in patients with alcoholic liver disease (ALD ranges between 5 % and 40 %. The loss of BMD in ALD is the result of an imbalance between bone formation and resorption. Its pathogenesis is multifactorial and includes the toxic effects of alcohol on bone and endocrine and nutritional disorders secondary to alcoholism and a deficiency of osteocalcin, vitamin D and insulin growth factor-1. The diagnosis of BMD alterations in ALD is based on its measurement using bone densitometry. Treatment includes smoking and alcohol cessation and general measures such as changes in nutrition and exercise. Calcium and vitamin D supplements are recommended in all patients with ALD and osteoporosis. Bisphosphonates are the most commonly prescribed drugs for the specific treatment of this condition. Alternatives include raloxifene, hormone replacement therapy and calcitonin. This review will address the most important aspects involved in the clinical management of abnormal BMD in the context of ALD, including its prevalence, pathogenesis and diagnosis. We will also review the treatment of osteoporosis in CLD in general, focusing on specific aspects related to bone loss in ALD.

    The first principles calculations have been carried out to investigate the structural, electronic band structure density of states along with the projected density of states for poly(vinyl alcohol). Our structural calculation suggests that the poly(vinyl alcohol) exhibits monoclinic structure. The calculated structural lattice parameters are in excellent agreement with available experimental values. The band structure calculations reveal that the direct and indirect band gaps are 5.55 eV and 5.363 eV respectively in accordance with experimental values.

    Sexual violence continues to be a significant public health problem worldwide with serious consequences for individuals and communities. The implementation of prevention strategies that address risk and protective factors for sexual violence at the community level are important components of a comprehensive approach, but few such strategies have been identified or evaluated. The current review explores one potential opportunity for preventing sexual violence perpetration at the community level: alcohol policy. Alcohol policy has the potential to impact sexual violence perpetration through the direct effects of excessive alcohol consumption on behavior or through the impact of alcohol and alcohol outlets on social organization within communities. Policies affecting alcohol pricing, sale time, outlet density, drinking environment, marketing, and college environment are reviewed to identify existing evidence of impact on rates of sexual violence or related outcomes, including risk factors and related health behaviors. Several policy areas with initial evidence of an association with sexual violence outcomes were identified, including policies affecting alcohol pricing, alcohol outlet density, barroom management, sexist content in alcohol marketing, and policies banning alcohol on campus and in substance-free dorms. We identify other policy areas with evidence of an impact on related outcomes and risk factors that may also hold potential as a preventative approach for sexual violence perpetration. Evidence from the current review suggests that alcohol policy may represent one promising avenue for the prevention of sexual violence perpetration at the community level, but additional research is needed to directly examine effects on sexual violence outcomes.

    Although numerous studies have found a positive association between the density of alcohol establishments and various types of crime, few have examined how neighborhood attributes (e.g., schools, parks) could moderate this association. We used data from Minneapolis, MN with neighborhood as the unit of analysis (n = 83). We examined eight types of crime (assault, rape, robbery, vandalism, nuisance crime, public alcohol consumption, driving while intoxicated, underage alcohol possession/consumption) and measured density as the total number of establishments per roadway mile. Neighborhood attributes assessed as potential moderators included non-alcohol businesses, schools, parks, religious institutions, neighborhood activism, neighborhood quality, and number of condemned houses. Using Bayesian techniques, we created a model for each crime outcome (accounting for spatial auto-correlation and controlling for relevant demographics) with an interaction term (moderator × density) to test each potential moderating effect. Few interaction terms were statistically significant. The presence of at least one college was the only neighborhood attribute that consistently moderated the density-crime association, with the presence of a college attenuating the association between the density and three types of crime (assaults, nuisance crime, and public consumption). However, caution should be used when interpreting the moderating effect of college presence because of the small number of colleges in our sample. The lack of moderating effects of neighborhood attributes, except for presence of a college, suggests that the addition of alcohol establishments to any neighborhood, regardless of its other attributes, could result in an increase in a wide range of crime.

  16. Low-Density Lipoprotein and Intracerebral Hematoma Expansion in Daily Alcohol Users

    Gayle R. Pletsch

    2014-01-01

    Full Text Available Background: Epidemiological studies suggest that the intracerebral hemorrhage (ICH rate correlates with alcohol consumption. Alcohol leads to elevated blood pressure (BP and inhibition of platelet aggregation. These factors could promote excessive bleeding. To our knowledge, in the setting of normal liver function tests, there are no studies that have systematically evaluated the relationship between daily alcohol use and hematoma expansion. The aim of this study is to compare the baseline ICH characteristics, frequency of hematoma expansion, and outcomes in patients with ICH who are daily alcohol users with those who are not daily alcohol users. Methods: A retrospective chart review was performed on consecutive patients who presented from July 2008 to July 2013 to the Tulane University Hospital in New Orleans, La., USA, with a spontaneous ICH. Ninety-nine patients who met these criteria were admitted. Patients who underwent hematoma evacuation were excluded. Hemorrhage volumes were calculated based on the ABC/2 method. Low-density lipoprotein (LDL was dichotomized into low (2 and nonparametric equivalents where appropriate. ICH growth in 24 h and LDL were evaluated using linear regression. Results: Of the 226 patients who met inclusion criteria, 20.4% had a history of daily alcohol use. The average age was 61 years (range 19-94, 55.6% of the patients were males, and 67.1% were of African American origin. Daily alcohol use was associated with male gender, lower rate of home antihypertensive, higher presenting BP, and lower platelet counts, but there was no difference in ICH characteristics, ICH growth, or clinical outcome. Daily alcohol use in patients with a low LDL level was associated with supratentorial location and trends for lower baseline Glasgow Coma Scale score, higher ICH score, and follow-up ICH volume, but no significant difference in significant hematoma expansion or clinical outcome except for a trend for higher mortality was found

    Mounting epidemiological evidence indicates an association between the moderate ingestion of alcoholic beverages and higher bone mineral density (v. abstainers). More limited findings provide some evidence for translation of this association into reduced fracture risk, but further studies are required. Here, these data are reviewed and caveats in their assimilation, comparison and interpretation as well as in the use and application of bone health indices are discussed. Whilst it is concluded that evidence is now strong for the moderate alcohol-bone health association, at least in relation to bone mineral density, mechanisms are less clear. Both ethanol and non-ethanol components have been implicated as factors that positively affect bone health in the light of moderate consumption of alcoholic beverages, and four particular areas are discussed. First, recent findings suggest that moderate ethanol consumption acutely inhibits bone resorption, in a non-parathyroid hormone- and non-calcitonin-dependent fashion, which can only partly be attributed to an energy effect. Second, critical review of the literature does not support a role for moderate ethanol consumption affecting oestrogen status and leading to a knock-on effect on bone. Third, Si is present at high levels in certain alcoholic beverages, especially beer, and may have a measurable role in promoting bone formation. Fourth, a large body of work indicates that phytochemicals (e.g. polyphenols) from alcoholic beverages could influence bone health, but human data are lacking. With further work it is hoped to be able to model epidemiological observations and provide a clear pathway between the magnitude of association and the relative contribution of these mechanisms for the major classes of alcoholic beverage.

    2012-07-01

    In an effort to study the effect of substituent groups of the substrate on the alcohol dehydrogenase (ADH) reductions of aryl-alkyl ketones, several derivatives of acetophenone have been evaluated against ADHs from Lactobacillus brevis (LB) and Thermoanaerobacter sp. (T). Interestingly, ketones with non-demanding (neutral) para-substituents were reduced to secondary alcohols by these enzymes in enantiomerically pure form whereas those with demanding (ionizable) substituents could not be reduced. The effect of substrate size, their solubility in the reaction medium, electron donating and withdrawing properties of the ligand and also the electronic charge density distribution on the substrate molecules have been studied and discussed in detail. From the results, it is observed that the electronic charge distribution in the substrate molecules is influencing the orientation of the substrate in the active site of the enzyme and hence the ability to reduce the substrate.

    Full Text Available Backgroundγ-Glutamyl transferase (GGT is a well-known marker of chronic alcohol consumption or hepatobiliary diseases. A number of studies have demonstrated that serum levels of GGT are independently associated with cardiovascular and metabolic disorders. The purpose of this study was to test if serum GGT levels are associated with bone mineral density (BMD in Korean adults.MethodsA total of 462 subjects (289 men and 173 women, who visited Severance Hospital for medical checkup, were included in this study. BMD was measured using dual energy X-ray absorptiometry. Cross-sectional association between serum GGT and BMD was evaluated.ResultsAs serum GGT levels increased from the lowest tertile (tertile 1 to the highest tertile (tertile 3, BMD decreased after adjusting for confounders such as age, body mass index, amount of alcohol consumed, smoking, regular exercise, postmenopausal state (in women, hypertension, diabetes mellitus, and hypercholesterolemia. A multiple linear regression analysis showed a negative association between log-transformed serum GGT levels and BMD. In a multiple logistic regression analysis, tertile 3 of serum GGT level was associated with an increased risk for low bone mass compared to tertile 1 (odds ratio, 2.271; 95% confidence interval, 1.340 to 3.850; P=0.002.ConclusionSerum GGT level was inversely associated with BMD in Korean adults.

    Full Text Available Alcohol consumption often leads to elevated rates of violence yet alcohol access policies continue to relax across the globe. Our review establishes the extent alcohol policy can moderate violent crime through alcohol availability restrictions. Results were informed from comprehensive selection of peer-reviewed journals from 1950 to October 2015. Our search identified 88 relevant studies on alcohol access and violence conducted across 12 countries. Seventeen studies included quasi-control design, and 23 conducted intervention analysis. Seventy-two (82% reported a significant relationship between alcohol access and violent offences. Alcohol outlet studies reported the greatest percentage of significant results (93%, with trading hours (63%, and alcohol price following (58%. Results from baseline studies indicated the effectiveness of increasing the price of commonly consumed alcohol, restricting the hours of alcohol trading, and limiting the number of alcohol outlets per region to prevent violent offences. Unclear are the effects of tax reductions, restriction of on-premises re-entry, and different outlet types on violent crime. Further, the generalization of statistics over broad areas and the low number of control/intervention studies poses some concern for confounding or correlated effects on study results, and amount of information for local level prevention of interpersonal violence. Future studies should focus on gathering longitudinal data, validating models, limiting crime data to peak drinking days and times, and wherever possible collecting the joint distribution between violent crime, intoxication, and place. A greater up take of local level analysis will benefit studies comparing the influence of multiple alcohol establishment types by relating the location of a crime to establishment proximity.

  8. Computational Design of Non-natural Sugar Alcohols to Increase Thermal Storage Density: Beyond Existing Organic Phase Change Materials.

    2016-09-14

    Thermal storage, a technology that enables us to control thermal energy, makes it possible to reuse a huge amount of waste heat, and materials with the ability to treat larger thermal energy are in high demand for energy-saving societies. Sugar alcohols are now one promising candidate for phase change materials (PCMs) because of their large thermal storage density. In this study, we computationally design experimentally unknown non-natural sugar alcohols and predict their thermal storage density as a basic step toward the development of new high performance PCMs. The non-natural sugar alcohol molecules are constructed in silico in accordance with the previously suggested molecular design guidelines: linear elongation of a carbon backbone, separated distribution of OH groups, and even numbers of carbon atoms. Their crystal structures are then predicted using the random search method and first-principles calculations. Our molecular simulation results clearly demonstrate that the non-natural sugar alcohols have potential ability to have thermal storage density up to ∼450-500 kJ/kg, which is significantly larger than the maximum thermal storage density of the present known organic PCMs (∼350 kJ/kg). This computational study suggests that, even in the case of H-bonded molecular crystals where the electrostatic energy contributes mainly to thermal storage density, the molecular distortion and van der Waals energies are also important factors to increase thermal storage density. In addition, the comparison between the three eight-carbon non-natural sugar alcohol isomers indicates that the selection of preferable isomers is also essential for large thermal storage density.

    We examined relationships between alcohol-related neighborhood context, protective home and family management practices, and alcohol use among urban, racial/ethnic minority, adolescents. The sample comprised 5,655 youth who were primarily low SES (72%), African American (43%) and Hispanic (29%). Participants completed surveys in 2002-2005 (ages 11-14 years). Items assessed alcohol use, accessibility of alcohol at home and parental family management practices. Neighborhood context measures included: (1) alcohol outlet density; (2) commercial alcohol accessibility; (3) alcohol advertisement exposure; and (4) perceived neighborhood strength, reported by parents and community leaders. Structural equation modeling was used to assess direct and indirect relationships between alcohol-related neighborhood context at baseline, home alcohol access and family management practices in seventh grade, and alcohol use in eighth grade. Neighborhood strength was negatively associated with alcohol use (beta = -0.078, p alcohol advertisements was positively associated with alcohol use (beta = 0.043, p alcohol access were associated with home alcohol access (beta = 0.050, p alcohol access showed a positive association with alcohol use (beta = 0.401, p alcohol access may partially mediate the relationship between neighborhood strength and alcohol use (beta = 0.025, p alcohol access and improving family management practices may be key to preventive efforts to reduce alcohol use.

    Recent studies have linked alcoholism with a dysfunctional neural reward system. Although several electrophysiological studies have explored reward processing in healthy individuals, such studies in alcohol-dependent individuals are quite rare. The present study examines theta oscillations during reward processing in abstinent alcoholics. The electroencephalogram (EEG) was recorded in 38 abstinent alcoholics and 38 healthy controls as they performed a single outcome gambling task, which involved outcomes of either loss or gain of an amount (10 or 50¢) that was bet. Event-related theta band (3.0-7.0 Hz) power following each outcome stimulus was computed using the S-transform method. Theta power at the time window of the outcome-related negativity (ORN) and positivity (ORP) (200-500 ms) was compared across groups and outcome conditions. Additionally, behavioral data of impulsivity and task performance were analyzed. The alcoholic group showed significantly decreased theta power during reward processing compared to controls. Current source density (CSD) maps of alcoholics revealed weaker and diffuse source activity for all conditions and weaker bilateral prefrontal sources during the Loss 50 condition when compared with controls who manifested stronger and focused midline sources. Furthermore, alcoholics exhibited increased impulsivity and risk-taking on the behavioral measures. A strong association between reduced anterior theta power and impulsive task-performance was observed. It is suggested that decreased power and weaker and diffuse CSD in alcoholics may be due to dysfunctional neural reward circuitry. The relationship among alcoholism, theta oscillations, reward processing, and impulsivity could offer clues to understand brain circuitries that mediate reward processing and inhibitory control.

    Full Text Available Interest has been increasing in regulating the location and number of tobacco vendors as part of a comprehensive tobacco control program. The objective of this paper is to examine the distribution of tobacco outlets in a large jurisdiction, to assess: (1 whether tobacco outlets are more likely to be located in vulnerable areas; and (2 what proportion of tobacco outlets are located close to schools. Retail locations across the Province of Ontario from Ministry of Health Promotion data were linked to 2006 Census data at the neighbourhood level. There was one tobacco retail outlet for every 1,000 people over age 15 in Ontario. Density of outlets varied by public health unit, and was associated with the number of smokers. Tobacco outlets were more likely to be located in areas that had high neighbourhood deprivation, in both rural and urban areas. Outlets were less likely to be located in areas with high immigrant populations in urban areas, with the reverse being true for rural areas. Overall, 65% of tobacco retailers were located within 500 m of a school. The sale of tobacco products is ubiquitous, however, neighbourhoods with lower socio-economic status are more likely to have easier availability of tobacco products and most retailers are located within walking distance of a school. The results suggest the importance of policies to regulate the location of tobacco retail outlets.

    Full Text Available A nanocomposite polymer membrane based on quaternized poly(vinyl alcohol/fumed silica (QPVA/FS was prepared via a quaternization process and solution casting method. The physico-chemical properties of the QPVA/FS membrane were investigated. Its high ionic conductivity was found to depend greatly on the concentration of fumed silica in the QPVA matrix. A maximum conductivity of 3.50 × 10−2 S/cm was obtained for QPVA/5%FS at 60 °C when it was doped with 6 M KOH. The permeabilities of methanol and ethanol were reduced with increasing fumed silica content. Cell voltage and peak power density were analyzed as functions of fumed silica concentration, temperature, methanol and ethanol concentrations. A maximum power density of 96.8 mW/cm2 was achieved with QPVA/5%FS electrolyte using 2 M methanol + 6 M KOH as fuel at 80 °C. A peak power density of 79 mW/cm2 was obtained using the QPVA/5%FS electrolyte with 3 M ethanol + 5 M KOH as fuel. The resulting peak power densities are higher than the majority of published reports. The results confirm that QPVA/FS exhibits promise as a future polymeric electrolyte for use in direct alkaline alcoholic fuel cells.

    This paper begins to describe and explicate the specific mechanisms by which alcohol use and the alcohol use environment contribute to specific types of child maltreatment. These mechanisms relating alcohol outlet densities to child maltreatment described here include effects on social disorganization, parent's drinking behaviors, and parental supervision. By investigating potential mechanisms, new information could be obtained on the importance and role of alcohol and their availability in the etiology of child maltreatment. This knowledge can be used to further tailor interventions to those conditions most likely to prevent and reduce maltreatment.

    2013-12-01

    This study investigates how the relationship between dense concentrations of alcohol retailers and high rates of child maltreatment may be moderated by the presence of substance abuse service facilities. Using a cross-sectional design, the study utilized data from Bergen County, New Jersey on child maltreatment reports, alcohol-selling retailers, substance abuse service facilities, and the United States Census. Findings indicate child maltreatment rates were higher in neighborhoods with lower socioeconomic status and those with greater alcohol outlet density. Neighborhoods with easily accessed substance abuse service facilities had lower rates of child maltreatment. Additionally, the relationship between child maltreatment and alcohol outlet density was moderated by the presence of substance abuse service facilities. The study findings highlight the relevance of making primary prevention approaches readily available and using multi-sector collaboration to reduce child maltreatment.

    A 2 μm thick layer of TiO2 nanotube arrays was prepared on the surface of the Ti fibers of a nonwoven web electrode. After it was doped with Pd nanoparticles (1.5 mgPd  cm(-2) ), this anode was employed in a direct alcohol fuel cell. Peak power densities of 210, 170, and 160 mW cm(-2) at 80 °C were produced if the cell was fed with 10 wt % aqueous solutions of ethanol, ethylene glycol, and glycerol, respectively, in 2 M aqueous KOH. The Pd loading of the anode was increased to 6 mg cm(-2) by combining four single electrodes to produce a maximum peak power density with ethanol at 80 °C of 335 mW cm(-2) . Such high power densities result from a combination of the open 3 D structure of the anode electrode and the high electrochemically active surface area of the Pd catalyst, which promote very fast kinetics for alcohol electro-oxidation. The peak power and current densities obtained with ethanol at 80 °C approach the output of H2 -fed proton exchange membrane fuel cells.

    Neighborhood socioeconomic characteristics and alcohol availability may affect alcohol consumption, but adequate longitudinal research to support these hypotheses does not exist. We used data from the Multi-Ethnic Study of Atherosclerosis (MESA) (N = 6163) to examine associations of changes in neighborhood socioeconomic status (SES) and alcohol outlet density, with current, weekly, and heavy daily alcohol consumption in hybrid effects models. We also examined whether these associations were moderated by gender, race/ethnicity, and income. Increases in neighborhood SES were associated with decreases in the probability of current alcohol use after adjustment for age, gender, race/ethnicity, individual SES, marital status and time since baseline [probability ratio (PR) per SD increase in neighborhood SES = 0.96, 95% confidence interval (CI) (0.96.0.99)]. Increases in liquor store densities were associated with increases in weekly alcohol consumption [ratio of weekly drinks per SD increase in outlet density = 1.07, 95% CI (1.01.1.05) for men, PR = 1.11, 95% CI (1.01.1.21) for women]. Relationships between current alcohol use and neighborhood SES and between weekly beer consumption and neighborhood SES were generally stronger among those with higher incomes. Neighborhood socioeconomic context and the availability of alcohol may be important for understanding patterns of alcohol use over time, and for targeting interventions and policies to reduce harmful alcohol use.

    Full Text Available Abstract Background There is a popular belief that out-of-home eating outlets, which typically serve energy dense food, may be more commonly found in more deprived areas and that this may contribute to higher rates of obesity and related diseases in such areas. Methods We obtained a list of all 1301 out-of-home eating outlets in Glasgow, UK, in 2003 and mapped these at unit postcode level. We categorised them into quintiles of area deprivation using the 2004 Scottish Index of Multiple Deprivation and computed mean density of types of outlet (restaurants, fast food restaurants, cafes and takeaways, and all types combined, per 1000 population. We also estimated odds ratios for the presence of any outlets in small areas within the quintiles. Results The density of outlets, and the likelihood of having any outlets, was highest in the second most affluent quintile (Q2 and lowest in the second most deprived quintile (Q4. Mean outlets per 1,000 were 4.02 in Q2, 1.20 in Q4 and 2.03 in Q5. With Q2 as the reference, Odds Ratios for having any outlets were 0.52 (CI 0.32–0.84 in Q1, 0.50 (CI 0.31 – 0.80 in Q4 and 0.61 (CI 0.38 – 0.98 in Q5. Outlets were located in the City Centre, West End, and along arterial roads. Conclusion In Glasgow those living in poorer areas are not more likely to be exposed to out-of-home eating outlets in their neighbourhoods. Health improvement policies need to be based on empirical evidence about the location of fast food outlets in specific national and local contexts, rather than on popular 'factoids'.

    This study examines the importance of food prices and restaurant and food store outlet availability for child body mass index (BMI). We use the 1998, 2000 and 2002 waves of the child-mother merged files from the 1979 cohort of the National Longitudinal Survey of Youth combined with fruit and vegetable and fast food price data obtained from the American Chamber of Commerce Researchers Association and outlet density data on fast food and full-service restaurants and supermarkets, grocery stores and convenience stores obtained from Dun & Bradstreet. Using a random effects estimation model, we found that a 10% increase in the price of fruits and vegetables was associated with a 0.7% increase in child BMI. Fast food prices were not found to be statistically significant in the full sample but were weakly negatively associated with BMI among adolescents with an estimated price elasticity of -0.12. The price estimates were robust to whether we controlled for outlet availability based on a per capita or per land area basis; however, the association between food outlets and child BMI differed depending on the definition. The associations of fruit and vegetable and fast food prices with BMI were significantly stronger both economically and statistically among low- versus high-socioeconomic status children. The estimated fruit and vegetable and fast food price elasticities were 0.14 and -0.26, respectively, among low-income children and 0.09 and -0.13, respectively, among children with less educated mothers.

    A new low-density lipoprotein (LDL) adsorbent with phosphate groups as the ligand was prepared in this study. Macroporous poly(vinyl acetate-co-triallyl isocyanurate) microspheres were prepared using a free-radical suspension polymerization method. A hydrolysis reaction in sodium hydroxide/methanol changed the materials into poly(vinyl alcohol) (PVA) microspheres. Further reaction with phosphorus oxychloride in anhydrous DMF led to the LDL adsorbent PVA-phosphate microspheres. The preparation conditions such as reaction time, temperature and the amount of phosphorus oxychloride were optimized. The adsorption of plasma lipoproteins was examined by in vitro adsorption assays. The influence of adsorption time, plasma volume and ionic strength on the adsorption capacity was investigated. The circulation adsorption showed that the pathogenic lipoproteins in the plasma such as total cholesterol (TC), LDL and triglyceride (TG) could be removed markedly, in which the removal percentages were 42.9%, 45.0% and 44.74%, respectively. However, the reduction of high-density lipoprotein (HDL) and other normal plasma components was very slight. For in vivo experiment, rabbits were fed with high-cholesterol food to develop a hyperlipidemia model and treated by extracorporeal blood perfusion using the PVA-phosphate columns. Eight hyperlipidemia rabbits were treated with the PVA-phosphate adsorbent, and the removal of TC, LDL and TG was 45.03 +- 6.64%, 48.97 +- 9.92% and 35.42 +- 14.17%, respectively. The sterilization and storage tests showed that the adsorbent was chemically and functionally stable. It could be easily sterilized by a common method and stored for months without loss of adsorption capacity. Therefore, this new PVA-phosphate-based LDL adsorbent may have potential for application in LDL apheresis.

    Full Text Available Introduction: Injuries of the peripheral nerve system affect the neurons cell body leading to axon injury. Cannabis sativa plant has anti oxidant and anti apoptotic effects. Therefore the aim of present study was to study the neuroprotective effect of alcoholic extract of cannabis sativa leaves on neuronal density of alpha motoneurons in spinal cord after sciatic nerve injury in rats. Methods: In this experimental research, animals were divided into four groups; A: control, B: compression, C: compression+ treatment with 25 mg/kg alcoholic extract, D: compression + treatment with 50 mg/kg extract (n=8. At first, sciatic nerve compression in B, C and D groups was achieved for 60 seconds using locker pincers. Alcoholic extract was injected intra peritoneally in the first and second weeks after compression. Then 28 days after compression, under profusion method, the lumbar spinal cord was sampled and the numerical density in each group was compared with the compression group. The data was analyzed with the use of Minitab 14 software and ANOVA statistical test. Results: Neuronal density showed a meaningful difference in the compression and control groups(P<0.001. Neuronal density in treatment groups(25, 50 mg/kg also had a meaningful increase(P<0.001 as compared to the compression group. Conclusion: Alcoholic extract of cannabis sativa leaves has a neuroprotective effect on spinal cord alpha motoneurons after injury. This could be due to growth and regeneration factors present in the alcoholic extract of cannabis sativa leaves that induce regeneration process in injured neurons or prevent degeneration.

    The authors examined the relationship of alcohol outlet density (AOD) and neighborhood poverty with binge drinking and alcohol-related problems among drinkers in married and cohabitating relationships and assessed whether these associations differed across sex. A U.S. national population couples survey was linked to U.S. Census data on AOD and neighborhood poverty. The 1,784 current drinkers in the survey reported on their binge drinking, alcohol-related problems, and other covariates. AOD was defined as the number of alcohol outlets per 10,000 persons and was obtained at the zip code level. Neighborhood poverty was defined as having a low (poverty at the census tract level. We used logistic regression for survey data to estimate odds ratios and 95% confidence intervals and tested for differences of associations by sex. Associations of neighborhood poverty with binge drinking were stronger for male than for female drinkers. The association of neighborhood poverty with alcohol-related problems was also stronger for men than for women. We observed no relationships between AOD and binge drinking or alcohol-related problems in this couples survey. Efforts to reduce binge drinking or alcohol-related problems among partners in committed relationships may have the greatest impact if targeted to male drinkers living in high-poverty neighborhoods. Binge drinking and alcohol-related problems, as well as residence in an impoverished neighborhood are risk factors for intimate partner violence (IPV) and other relationship conflicts.

    Five potential reaction mechanisms, each leading to the formation of an α-O-4-linked coniferyl alcohol dimer, and one scheme leading to the formation of a recently proposed free-radical coniferyl alcohol trimer were assessed using density functional theory (DFT) calculations. These potential reaction mechanisms were evaluated using both the calculated Gibbs free energies, to predict the spontaneity of the constituent reactions, and the electron-density mapped Fukui function, to determine the most reactive sites of each intermediate species. The results indicate that each reaction in one of the six mechanisms is thermodynamically favorable to those in the other mechanisms; what is more, the Fukui function for each free radical intermediate corroborates with the thermochemical results for this mechanism. This mechanism proceeds via the formation of two distinct free-radical intermediates, which then react to produce the four α-O-4 stereoisomers.

    2013-11-01

    The interaction of acrolein and allyl alcohol with the Ag(111) surface has been studied by means of periodic density functional theory based calculations including explicitly dispersion terms. Different coverage values have been explored going from isolated adsorbed molecules to isolated dimers, interacting dimers or ordered overlayers. The inclusion of the dispersion terms largely affects the calculated values of the adsorption energy and also the distance between adsorbed molecule and the metallic surface but much less the adsorbate-adsorbate interactions. Owing to the large dipole moment of acrolein, the present calculations predict that at high coverage this molecule forms a stable extensive two-dimensional network on the surface, caused by the alignment of the adsorbate dipoles. For the case of allyl alcohol, dimers and complex networks exhibit similar stability.

    Full Text Available BACKGROUND: Adolescence is a critical stage for bone accrual. It is also decisive for the establishment of behaviors such as smoking and alcohol drinking. OBJECTIVE: To quantify the short- and long-term associations between smoking and drinking initiation and bone mineral density in adolescent girls. METHODS: We used prospective data from 731 girls identified in public and private schools in Porto, Portugal. Evaluations were conducted when participants were 13 and 17 years old. Bone mineral density (BMD was measured at the forearm by dual-energy X-ray absorptiometry and weight, height and fat-free mass were measured. Pubertal development status was estimated using menarche age. Self-administered questionnaires were used to collect data on smoking and alcohol drinking, physical exercise and calcium and vitamin D intakes. BMD in early and late adolescence was analyzed as a continuous or dichotomous (Z-score cutoff: -1.0 variable. Associations were calculated using linear or logistic regression. RESULTS: Over one quarter of these girls had tried smoking by 13, while 59% had drunk alcoholic beverages and 20% had experienced both behaviors by that age. Lower mean BMD at 17 years of age was observed in girls who had ever smoked by 13, as well as in those who reported drinking at that age. There were no significant cross-sectional associations between experience and frequency of smoking or drinking and BMD at 13 years of age. However, we observed significant associations between BMD z-score<-1 in late adolescence and having ever smoked by 13, after adjustment for menarche age and sports practice, (OR = 1.92; 95% CI: 1.21, 3.05 and with ever smoking and drinking in the same period (OR = 2.33; 95% CI: 1.36, 4.00. CONCLUSION: Our study adds prospective evidence to the role of early initiation of smoking and alcohol drinking as relevant markers of lower bone mineral density in late adolescence.

    The obesogenic environment model would suggest that increased availability or access to energy dense foods which are high in saturated fat may be related to obesity. The association between food outlet location, deprivation, weight status and ethnicity was analysed using individual level data on a sample of 1198 pregnant women in the UK Born in Bradford cohort using geographic information systems (GIS) methodology. In the non South Asian group 24% were obese as were 17% of the South Asian group (BMI > 30). Food outlet identification methods revealed 886 outlets that were allocated into 5 categories of food shops. More than 95% of all participants lived within 500 m of a fast food outlet. Women in higher areas of deprivation had greater access to fast food outlets and to other forms of food shops. Contrary to hypotheses, there was a negative association between BMI and fast food outlet density in close (250 m) proximity in the South Asian group. Overall, these women had greater access to all food stores including fast food outlets compared to the non South Asian group. The stronger association between area level deprivation and fast food density than with area level deprivation and obesity argues for more detailed accounts of the obesogenic environment that include measures of individual behaviour.

    A large body of literature has reported differences in exposure to environments supporting either healthy (e.g. supermarkets) or unhealthy (e.g. fast food outlets) dietary choices by neighborhood characteristics. We explored the associations of both supermarkets and fast food outlets availability with neighborhood characteristics, and clustering of these two outlet types in a largely rural state. Compared to block groups without a supermarket, those with a supermarket had a significantly higher income, higher housing value, larger population with high school education and above, lower minority population and lower population living below poverty even after controlling for urbanicity and population density of census block groups. Surprisingly, a similar relationship was found for block groups with and without fast food outlets. This was due to spatial co-occurrence and clustering of fast food outlets around supermarket locations. Hence, future studies exploring the associations of food environment with diet or diet-related health outcome should concurrently examine all aspects of food environment (healthy and unhealthy).

Extracapsular implant rupture and bilateral axillary lymphadenopathy indicated explantation, capsulectomy, and selective lymph node excision. Histology demonstrated silicone lymphadenopathy with no evidence of malignancy. Over the subsequent 12 months, she developed progressive locoregional lymphadenopathy involving bilateral cervical, axillary, and internal mammary groups, resulting in bilateral thoracic outlet syndrome. We report the unusual presentation, progression, and the ultimate surgical management of this patient.

    2015-06-01

    Full Text Available Low-density lipoprotein receptor-related protein 6 (LRP6 is a member of the low-density lipoprotein receptor family and has a unique structure, which facilitates its multiple functions as a co-receptor for Wnt/β-catenin signaling and as a ligand receptor for endocytosis. The role LRP6 plays in metabolic regulation, specifically in the nutrient-sensing pathway, has recently garnered considerable interest. Patients carrying an LRP6 mutation exhibit elevated levels of LDL cholesterol, triglycerides, and fasting glucose, which cooperatively constitute the risk factors of metabolic syndrome and atherosclerosis. Since the discovery of this mutation, the general role of LRP6 in lipid homeostasis, glucose metabolism, and atherosclerosis has been thoroughly researched. These studies have demonstrated that LRP6 plays a role in LDL receptor-mediated LDL uptake. In addition, when the LRP6 mutant impaired Wnt-LRP6 signaling, hyperlipidemia, non-alcoholic fatty liver disease, and atherosclerosis developed. LRP6 regulates lipid homeostasis and body fat mass via the nutrient-sensing mechanistic target of the rapamycin (mTOR pathway. Furthermore, the mutant LRP6 triggers atherosclerosis by activating platelet-derived growth factor (PDGF-dependent vascular smooth muscle cell differentiation. This review highlights the exceptional opportunities to study the pathophysiologic contributions of LRP6 to metabolic syndrome and cardiovascular diseases, which implicate LRP6 as a latent regulator of lipid metabolism and a novel therapeutic target for nutritional intervention.

  1. Obesity-related eating behaviors are associated with higher food energy density and higher consumption of sugary and alcoholic beverages: a cross-sectional study.

    Directory of Open Access Journals (Sweden)

    Maritza Muñoz-Pareja

    Full Text Available OBJECTIVES: Obesity-related eating behaviors (OREB are associated with higher energy intake. Total energy intake can be decomposed into the following constituents: food portion size, food energy density, the number of eating occasions, and the energy intake from energy-rich beverages. To our knowledge this is the first study to examine the association between the OREB and these energy components. METHODS: Data were taken from a cross-sectional study conducted in 2008-2010 among 11,546 individuals representative of the Spanish population aged ≥ 18 years. Information was obtained on the following 8 self-reported OREB: not planning how much to eat before sitting down, eating precooked/canned food or snacks bought at vending machines or at fast-food restaurants, not choosing low-energy foods, not removing visible fat from meat or skin from chicken, and eating while watching TV. Usual diet was assessed with a validated diet history. Analyses were performed with linear regression with adjustment for main confounders. RESULTS: Compared to individuals with ≤ 1 OREB, those with ≥ 5 OREB had a higher food energy density (β 0.10; 95% CI 0.08, 0.12 kcal/g/day; p-trend<0.001 and a higher consumption of sugary drinks (β 7; 95% CI -7, 20 ml/day; p-trend<0.05 and of alcoholic beverages (β 24; 95% CI 10, 38 ml/day; p-trend<0.001. Specifically, a higher number of OREB was associated with higher intake of dairy products and red meat, and with lower consumption of fresh fruit, oily fish and white meat. No association was found between the number of OREB and food portion size or the number of eating occasions. CONCLUSIONS: OREB were associated with higher food energy density and higher consumption of sugary and alcoholic beverages. Avoiding OREB may prove difficult because they are firmly socially rooted, but these results may nevertheless serve to palliate the undesirable effects of OREB by reducing the associated energy intake.

    Objective:To re-examine the detailed anatomy of the muscular system at the bladder neck and proximal urethra in the male and to explore its function in urinary continence and micturition further. Methods:The pelvic organs, including bladder, prostate, and rectum, were obtained from 20 formalin-fixed adult male ca-davers and were removed from the pelvic cavity and embedded in celloidin in their entirety. The embedded block was cut into successive slices with an immersing-alcohol microtome. Results:Circular muscle fibers of the detrusor at the bladder outlet consist of the anterior downward projected circular muscle fibers of the bladder outlet ( AD-PC) , the bilateral accumulated circular fibers, and the posterior circular fibers of the bladder outlet. Together, these fibers concentrically surround the internal urethral orifice and trigone muscle. The lower part of the ADPC surrounds the ventral surface of the proximal urethra. Longitudinal muscle fibers are radially inserted into the circu-lar muscle around the internal urethral orifice. Numerous fibers from the ventral longitudinal muscle are inserted in-to the lower part of the ADPC. The upper part of the trigone muscle exists in bladder cavity;the lower part extends into the proximal urethra to surround the posterior and posterolateral surface of the urethra. Conclusions:The AD-PC and the upward extension of the rhabdosphincter comprise the anterior fibromuscular stroma. The circular mus-cle of the bladder outlet may be responsible for closure; the longitudinal muscle of the bladder outlet may be re-sponsible for opening of the internal urethral orifice and proximal urethra.

    1990-07-01

    Full Text Available Forty patients with symptoms of neuro-vascular compression in the upper extremities were subjected to impedance plethysmographic study using Parulkar′s method. Two patients recorded decreased blood flow (BFI in supine position and were diagnosed as having partial occlusion at subclavian level. Sixteen of the patients recorded decreased BFI on 90 degrees abduction and hyper-abduction. Twelve of these patients had radiological evidence of anomalous cervicle ribs. In remaining four patients extrinsic impression on the subclavian artery due to fibrous deposits was confirmed by arteriography. Remaining 22 patients recorded normal impedance plethysmograms. Impedance plethysmography thus provided a non-invasive modality for confirmation of vascular compression in thoracic outlet syndrome.

    The present work focuses on the design of a drug delivery system for systemic, controlled release of the poorly soluble breast cancer drug, letrozole. The drug delivery system was prepared in two steps: a low density polyethylene (LDPE) substrate surface was grafted with maleic anhydride (MA) via solution grafting technique. Next, the grafted substrate was used to anchor a hydrophilic polymeric drug release system consisting of poly (vinyl alcohol) (PVA). The PVA anchored MA grafted LDPE (PVA/MA-g-LDPE) drug release system was used for the controlled release of letrozole. This system was characterized using ATR-FTIR spectrophotometry, surface profilometry, and scanning electron microscopy. Biocompatibility studies were also carried out. In vitro release studies of letrozole from the system were performed in distilled water and phosphate buffer saline (PBS) at 37°C. Release of ∼90% letrozole from hydrophilic PVA matrix was observed within a period of 35 days. A high correlation coefficient (R(2)=0.99) was seen between the release of letrozole in distilled water and PBS. Cytotoxicity studies using MTT colorimetric assay suggested that all samples were biocompatible. It is concluded that the letrozole delivery system appears to overcome the limitations associated with letrozole by providing enhanced drug dissolution rate, controlled release and improved bioavailability of the incorporated drug and, therefore, seems to have extended therapeutic effects.

    Densities, p, ultrasonic speeds, u, viscosities, η, and refractive indices, n, of pure benzene, benzyl alcohol (BA),benzonitrile (BN), benzoyl chloride (BC), chlorobenzene (CB) and their thirty six binary mixtures, with benzene as common component, were measured at 303.15 K over the entire mole fraction range. From these experimental data the values of deviations in ultrasonic speed, Au, isentropic compressibility, Δks, excess acoustic impedance, ZE, deviation in viscosity, Δη, and excess Gibbs free energy of activation of viscous flow, G*E, and partial molar isentropic compressibility, Kφ,2 of BA, BN, BC and CB in benzene were computed. The variation of these derived functions with composition of the mixtures suggested the increased cohesion (molecular order) in the solution and that interaction (A-B)>(A-A) or (B-B). Moreover, theoretical prediction of ultrasonic speed, viscosity and refractive index of all the four binary mixtures was made on the basis of empirical and semi-empirical relations by using the experimental values of the pure components. Comparison of theoretical results with the experimental values was made in order to assess the suitability of these relations in reproducing the experimental values of u, η and n. Also, molecular radii of pure liquids and the average molecular radii of binary mixtures were evaluated using the corresponding refractive indices of pure liquids and binary mixtures. The average molecular radii of binary mixtures were found to be additive with respect to mole fraction of the pure component.

    Full Text Available INTRODUCTION Gastric outlet obstruction (GOO is obstruction in the first part of duodenum secondary to cicatrised duodenal ulcer or proximally where the diagnosis of carcinoma is most probable. GOO can be a diagnostic and treatment dilemma. Once a mechanical obstruction is confirmed, differentiate between benign and malignant processes. Cicatrized duodenal ulcer was the most common cause of GOO. But with increased awareness, change in the dietary habits and availability of H2 receptor blockers and Proton Pump Inhibitors and H pylori kits all have resulted in decreased incidence of patients requiring surgery and also the complications like pyloric stenosis have reduced. At the same time the incidence of antral carcinoma of stomach producing GOO has comparatively increased, which may be due to increased early diagnosis of the condition with the help of flexible fibro optic endoscope. AIMS & OBJECTIVES To study and identify the cause of cases of GOO with respect to benign peptic ulcer and malignancy of stomach. MATERIALS AND METHODS An observational study comparing of 30 cases of GOO. An elaborate study of the cases with regard to history, clinical features, routine and special investigation, pre operative treatment, operative findings, post operative management and complications in the post operative period is done. Apart from routine surgical profile special investigations like serum electrolytes, barium meal study, Upper GI Endoscopy and ultrasound abdomen and pelvis will be carried. For peptic ulcer disease truncal vagotomy with posterior gastrojejunostomy was done and for carcinoma partial gastrectomy with Billroth II reconstruction or anterior GJ or palliative resection with anterior GJ were done. INCLUSION CRITERIA 1. Peptic ulcer disease 2. Carcinoma pyloric antrum, 3. Benign neoplasm of stomach. EXCLUSION CRITERIA 1. Carcinoma stomach with liver metastasis, ascites, peritoneal implantation, 2. Gastro duodenal tuberculosis. ETHICAL ISSUES

This review aims to summarise this body of research and highlight areas for future work. Thirty three studies were found that had assessed the geography of these outlets. Fourteen studies showed a positive association between availability of FF outlets and increasing deprivation. Another 13 studies also included overweight or obesity data and showed conflicting results between obesity/overweight and FF outlet availability. There is some evidence that FF availability is associated with lower fruit and vegetable intake. There is potential for land use policies to have an influence on the location of new FF outlets. Further research should incorporate good quality data on FF consumption, weight and physical activity.

    Full Text Available Das Thoracic Outlet-Syndrom (TOS ist ein äußerst kontrovers diskutiertes Engpasssyndrom, das für ca. 4 % aller nicht-traumatischen Paresen des Plexus brachialis verantwortlich ist [1]. Nach Wilbourn [2] wird zwischen einem neurogenen TOS (klassisches TOS und einem fraglichen (disputed TOS differenziert. Aus pathophysiologischer Sicht wird ein neurogenes (ca. 90 % aller TOS, ein arterielles und ein venöses TOS differenziert [3, 4]. Die einzelnen Formen können aufgrund unterschiedlicher Symptome gut voneinander abgegrenzt werden. Häufigste Ursachen sind abnorme anatomische Strukturen (fibröse Bänder etc. oder über Jahre ausgeübte muskuläre Tätigkeiten (z. B. Sportler, Musiker. Zur Diagnose werden klinische, lektrophysiologische, radiologische und Neuroimaging-Verfahren herangezogen. Wenngleich die neuen Techniken wie MRT, MRA und Sonographie die diagnostische Sicherheit erhöht haben, ähnelt die Diagnose eines TOS einem Indizienprozess und erfordert eine sorgfältige Analyse aller Daten. Therapeutisch ist bis heute der Wert der konservativen Therapie nicht durch kontrollierte Studien belegt. Die Therapieansätze basieren auf pathophysiologischen Überlegungen. Während beim vaskulären TOS ein rasches chirurgisches Eingreifen erforderlich ist, sollte beim neurogenen TOS, außer bei Progredienz der Symptomatik, zunächst ein konservativer Therapieversuch unternommen werden.

    1977-06-01

    Small scale experiments involving water flows are used to provide mean flow and turbulence field data for LMFBR outlet plenum flows. Measurements are performed at Reynolds Number (Re) values of 33000 and 70000 in a 1/15-scale FFTF geometry and at Re = 35000 in a 3/80-scale CRBR geometry. The experimental behavior is predicted using two different turbulence model computer programs, TEACH-T and VARR-II. It is found that the qualitative nature of the flow field within the plenum depends strongly upon the distribution of the mean inlet velocity field, upon the degree of inlet turbulence, and upon the turbulence momentum exchange model used in the calculations. It is found in the FFTF geometry that the TEACH-T predictions are better than that of VARR-II, and in the CRBR geometry neither code provides a good prediction of the observed behavior. From the sensitivity analysis, it is found that the production and dissipation of turbulence are the dominant terms in the transport equations for turbulent kinetic energy and turbulent energy dissipation rate, and the diffusion terms are relatively small. From the same study a new set of empirical constants for the turbulence model is evolved for the prediction of plenum flows.

    We discuss MRI findings in patients with thoracic outlet syndrome (TOS). A total of 100 neurovascular bundles were evaluated in the interscalene triangle (IS), costoclavicular (CC), and retropectoralis minor (RPM) spaces. To exclude neurogenic abnormality, MRIs of the cervical spine and brachial plexus (BPL) were obtained in neutral. To exclude compression on neurovascular bundles, sagittal T1W images were obtained vertical to the longitudinal axis of BPL from spinal cord to the medial part of the humerus, in abduction and neutral. To exclude vascular TOS, MR angiography (MRA) and venography (MRV) of the subclavian artery (SA) and vein (SV) in abduction were obtained. If there is compression on the vessels, MRA and MRV of the subclavian vessels were repeated in neutral. Seventy-one neurovascular bundles were found to be abnormal: 16 arterial-venous-neurogenic, 20 neurogenic, 1 arterial, 15 venous, 8 arterial-venous, 3 arterial-neurogenic, and 8 venous-neurogenic TOS. Overall, neurogenic TOS was noted in 69%, venous TOS in 66%, and arterial TOS in 39%. The neurovascular bundle was most commonly compressed in the CC, mostly secondary to position, and very rarely compressed in the RPM. The cause of TOS was congenital bone variations in 36%, congenital fibromuscular anomalies in 11%, and position in 53%. In 5%, there was unilateral brachial plexitis in addition to compression of the neurovascular bundle. Severe cervical spondylosis was noted in 14%, contributing to TOS symptoms. For evaluation of patients with TOS, visualization of the brachial plexus and cervical spine and dynamic evaluation of neurovascular bundles in the cervicothoracobrachial region are mandatory.

    Alcohol consumption interferes with the functioning of multiple organ systems, causing changes in the chemistry, physiology and pathology of tissues and cellular organelles. Although epigenetic modifications underlie the development of cancer, exposure to carcinogenic chemicals, such as alcohol, can also contribute to disease development. However, the effects of chronic alcoholism on normal or pre-carcinogenic cells/tissues in different organelles are not well understood. Therefore, we herein study the effect of alcohol consumption on colonic nucleus using control and azoxymethane (AOM) and dextran sulfate sodium (DSS) treated carcinogenic mice. Previous studies showed that progression of carcinogenesis is associated with increase in the degree of intranuclear nanoscale structural disorder. In the present work, we quantify the degree of nanostructural disorder as a measure of carcinogenesis. To accomplish this, transmission electron microscopy (TEM) imaging of respective colonic epithelial cell nuclei are use...

    We present an experimental study of the effect that an obstacle above the outlet of a silo has on the clogging probability. Both, the size of the orifice and the obstacle position are varied for a chosen obstacle size and shape. If the position of the obstacle is properly selected the clogging probability can be importantly reduced. Indeed, as the outlet size is increased - and we approach the critical size above which there is not clogging - the obstacle effect is enhanced. For the largest outlet size studied, the clogging probability is reduced by a factor of more than one hundred. We will show, using numerical simulations, that the physical parameter behind the reduction of the silo clogging seems to be the decrease of the vertical pressure at the outlet proximities.

    Background Excessive alcohol use contributes to public nuisance, antisocial behaviour, and domestic, interpersonal and sexual violence. We test whether licencing policies aimed at restricting its spatial and/or temporal availability, including cumulative impact zones, are associated with reductions in alcohol-related crime. Methods Reported crimes at English lower tier local authority (LTLA) level were used to calculate the rates of reported crimes including alcohol-attributable rates of sexual offences and violence against a person, and public order offences. Financial fraud was included as a control crime not directly associated with alcohol abuse. Each area was classified as to its cumulative licensing policy intensity for 2009–2015 and categorised as ‘passive’, low, medium or high. Crime rates adjusted for area deprivation, outlet density, alcohol-related hospital admissions and population size at baseline were analysed using hierarchical (log-rate) growth modelling. Results 284 of 326 LTLAs could be linked and had complete data. From 2009 to 2013 alcohol-related violent and sexual crimes and public order offences rates declined faster in areas with more ‘intense’ policies (about 1.2, 0.10 and 1.7 per 1000 people compared with 0.6, 0.01 and 1.0 per 1000 people in ‘passive’ areas, respectively). Post-2013, the recorded rates increased again. No trends were observed for financial fraud. Conclusions Local areas in England with more intense alcohol licensing policies had a stronger decline in rates of violent crimes, sexual crimes and public order offences in the period up to 2013 of the order of 4–6% greater compared with areas where these policies were not in place, but not thereafter.

    Purpose Identifying factors that contribute to optimal childhood bone development could help pinpoint strategies to improve long term bone health. A healthy diet positively influences bone health from before birth and during childhood. This study addressed a gap in the literature by examining the relationship between residential neighbourhood food environment and bone mass in infants and children. Methods 1107 children participating in the Southampton Women’s Survey, United Kingdom, underwent measurement of bone mineral density (BMD) and bone mineral content (BMC) at birth and four and/or six years by Dual-energy X-ray Absorptiometry (DXA). Cross-sectional observational data describing food outlets within the boundary of each participant’s neighbourhood were used to derive three measures of the food environment: the counts of fast food outlets, healthy speciality stores and supermarkets. Results Neighbourhood exposure to fast food outlets was associated with lower BMD in infancy (β=−0.23(z-score): 95% CI −0.38, −0.08), and lower BMC after adjustment for bone area and confounding variables (β=−0.17(z-score): 95% CI −0.32, −0.02). Increasing neighbourhood exposure to healthy speciality stores was associated with higher BMD at four and six years (β=0.16(z-score): 95% CI 0.00, 0.32 and β=0.13(z-score): 95% CI −0.01, 0.26 respectively). The relationship with BMC after adjustment for bone area and confounding variables was statistically significant at four years but not at six years. Conclusions The neighbourhood food environment pregnant mothers and young children are exposed to may effect bone development during early childhood. If confirmed in future studies, action to reduce access to fast food outlets could have benefits for childhood development and long term bone health. PMID:26458387

    PURPOSE. Assessing food environments often requires using commercially available data. Disparate methods used for classifying food outlets in these databases call for creating a classification approach using common definitions. A systematic strategy for reclassifying food stores and restaurants, as they appear in commercial databases, into categories that differentiate the availability of healthy options is described here. DESIGN AND SETTING. Commercially available data on food outlets including names, addresses, North American Industry Classification System codes, and associated characteristics was obtained for five New Jersey communities. ANALYSIS. A reclassification methodology was developed using criteria and definitions from the literature to categorize food outlets based on availability of healthy options. Information in the database was supplemented by systematic Internet and key word searches, and from phone calls to food outlets. RESULTS. The methodology resulted in 622 supermarket/grocery stores, 183 convenience stores, and 148 specialty stores in the original data to be reclassified into 58 supermarkets, 30 grocery stores, 692 convenience stores, and 115 specialty stores. Outlets from the original list of 1485 full-service restaurants and 506 limited-service restaurants were reclassified as 563 full-service restaurants and 1247 limited-service restaurants. Reclassification resulted in less than one-seventh the number of supermarkets and grocery stores, more than three times the number of convenience stores, and twice as many limited-service restaurants-a much less healthy profile than the one generated by using exclusively the commercial databases. CONCLUSION. An explicit and replicable strategy is proposed for reclassifying food outlets in commercial databases into categories that differentiate on the basis of healthy food availability. The intent is to contribute towards building a consensus among researchers on definitions used in public health

    Background and objective Alcohol abuse is common in the USA and is a well-established risk factor for violence. Other drug use and criminal activity are risk factors as well and frequently occur together with alcohol abuse. Firearm ownership is also common; there are >50 million firearm owners in the USA. This study assesses the relationships between alcohol and drug abuse and future violence among firearm owners, which no prior research has done. Design and study population This records-based retrospective cohort study will involve all persons who legally purchased handguns in California in 2001—approximately 116 000 individuals—with follow-up through the end of 2013. Methods The principal exposures include prior convictions for alcohol-related and drug-related offenses. The primary outcome measure is an arrest following handgun purchase for a violent Crime Index offense: homicide, rape, robbery or aggravated assault. Subjects will be considered at risk for outcome events for only as long as their residence in California can be established independently of outcome events. Covariates include individual characteristics (eg, age, sex, criminal history, firearm purchase history) and community characteristics (eg, demographics, socioeconomic measures, firearm ownership and alcohol outlet density). We will employ survival analytic methods, expressing effects as HRs. Discussion The results of this large-scale study are likely to be generalisable and to have important implications for violence prevention policies and programmes. PMID:26498316

    Catechins, a major component of green tea extract, have anti-hyperlipidemic effects. The present study investigated the effects of consumption of green tea with high-density catechins in non-alcoholic fatty liver disease (NAFLD) patients. Seventeen patients with NAFLD consumed green tea with high-density catechins, low-density catechins or a placebo for 12 weeks in a randomized double-blind study. Ultrasonography and computed tomography (CT) were performed at baseline and after 12 weeks. Serum alanine aminotransferase (ALT) levels and urine 8-isoprostane were monitored and compared to baseline at 4, 8 and 12 weeks. Body fat was significantly decreased in the high-density catechin group compared with the placebo and low-density catechin groups after 12 weeks of consumption. All the patients in the high-density catechin group showed a significantly improved liver-to-spleen CT attenuation ratio compared with the placebo and low-density catechin groups after 12 weeks of consumption. The high-density catechin group significantly decreased serum ALT levels and reduced urinary 8-isoprostane excretion compared with the placebo and low-density catechin group after 12 weeks of consumption. Based on a reduced proportion of body fat as estimated by bioimpedance measurement, increased liver-to-spleen CT attenuation ratio, decreased serum ALT levels and reduced urinary 8-isoprostane excretion, we concluded that 12 weeks of 700 ml per day of green tea containing >1 g catechin improved liver fat content and inflammation by reducing oxidative stress in patients with NAFLD.

  12. Update on endoscopic management of gastric outlet obstruction in children

    Chao, Hsun-Chin

    2016-01-01

    Endoscopic balloon dilatation (EBD) and surgical intervention are two most common and effective treatments for gastric outlet obstruction. Correction of gastric outlet obstruction without the need for surgery is an issue that has been tried to be resolved in these decades; this management has developed with EBD, advanced treatments like local steroid injection, electrocauterization, and stent have been added recently. The most common causes of pediatric gastric outlet obstruction are idiopathic hypertrophic pyloric stenosis, peptic ulcer disease followed by the ingestion of caustic substances, stenosis secondary to surgical anastomosis; antral web, duplication cyst, ectopic pancreas, and other rare conditions. A complete clinical, radiological and endoscopic evaluation of the patient is required to make the diagnosis, with complimentary histopathologic studies. EBD are used in exceptional cases, some with advantages over surgical intervention depending on each patient in particular and on the characteristics and etiology of the gastric outlet obstruction. Local steroid injection and electrocauterization can augment the effect of EBD. The future of endoscopic treatment seems to be aimed at the use of endoscopic electrocauterization and balloon dilatations.

    @@ Double outlet ventricle (DOV) is defined as a congenital heart disease with: (1) both great arteries arising completely, or almost completely (≥90%), from a single ventricle (usually, right ventricle); (2) an aortic valve having no fibre connection with mitral valve; and (3) the only outlet of the other ventricle is a ventricular septal defect (VSD). The incidence of DOV accounts for 1% of all congenital heart disease.1 Clinically there are three common types: Fallot type or double outlet right ventricle (DORV) with subaortic VSD with pulmonary stenosis; Eisenmenger type or DORV with subaortic VSD without pulmonary stenosis and Taussig-Bing type or DORV with subpulmonary VSD. Operative techniques are different according to the position of the VSD and great arteries and the presence or absence of ventricular outflow tract obstruction. The operative difficulty increases in the presence of coronary artery malformation. Recently, our research centre has treated 72 cases of patients suffering from double outlet ventricle. This article is the report of the operative methods and the outcomes.

  16. Do flexible alcohol trading hours reduce violence? A theory-based natural experiment in alcohol policy.

    Science.gov (United States)

    Humphreys, David K; Eisner, Manuel P

    2014-02-01

    Alcohol-related violence is a pressing public health concern. In 2005, the government of England and Wales took a controversial approach to preventing violence by removing restrictions on opening hours for alcohol outlets, thus increasing the availability of alcohol. The policy aimed to remove fixed closing times, which it claimed was contributing to urban violence occurring at peak closing times. It proposed to reduce violence and disorder by installing systems of 'staggered closing times'. This policy was criticised for overlooking established public health principles prioritising the control of alcohol availability in the prevention of alcohol-related harm. In this study, we treated the removal of trading hour restrictions as a natural experiment to test competing theoretical principles about the relationship between alcohol availability and violence. Our study took place in the City of Manchester over a four-year period 2004-2008. Detailed trading records for over 600 alcohol outlets were obtained, as were police records for all violent incidents. We found considerable variation in the implementation of extended trading hours across the city, which affected area-level exposure of changes in alcohol availability and staggered closing times. To isolate the effect of these changes on violence, we performed a dose-response analysis to examine whether improved staggering of closing hours (or increased alcohol availability) was associated with decreases in violence. We found no evidence to support the government-proposed hypothesis that staggered closing reduces violence. We also found no support for the alternative hypothesis; that increase alcohol availability would result in increased violence. This study provides an example of how better evidence can be generated from natural experiments by placing added emphasis on theory, causal mechanisms and implementation science.

  17. Effectiveness of policies restricting hours of alcohol sales in preventing excessive alcohol consumption and related harms.

    Local, state, and national policies that limit the hours that alcoholic beverages may be available for sale might be a means of reducing excessive alcohol consumption and related harms. The methods of the Guide to Community Preventive Services were used to synthesize scientific evidence on the effectiveness of such policies. All of the studies included in this review assessed the effects of increasing hours of sale in on-premises settings (in which alcoholic beverages are consumed where purchased) in high-income nations. None of the studies was conducted in the U.S. The review team's initial assessment of this evidence suggested that changes of less than 2 hours were unlikely to significantly affect excessive alcohol consumption and related harms; to explore this hypothesis, studies assessing the effects of changing hours of sale by less than 2 hours and by 2 or more hours were assessed separately. There was sufficient evidence in ten qualifying studies to conclude that increasing hours of sale by 2 or more hours increases alcohol-related harms. Thus, disallowing extensions of hours of alcohol sales by 2 or more should be expected to prevent alcohol-related harms, while policies decreasing hours of sale by 2 hours or more at on-premises alcohol outlets may be an effective strategy for preventing alcohol-related harms. The evidence from six qualifying studies was insufficient to determine whether increasing hours of sale by less than 2 hours increases excessive alcohol consumption and related harms.

    Alcohol is the most frequently consumed toxic substance in the world. Low to moderate daily intake of alcohol has been shown to have beneficial effects on the cardiovascular system. In contrast, exposure to high levels of alcohol for a long period could lead to progressive cardiac dysfunction and heart failure. Cardiac dysfunction associated with chronic and excessive alcohol intake is a specific cardiac disease known as alcoholic cardiomyopathy(ACM). In spite of its clinical importance, data on ACM and how alcohol damages the heart are limited. In this review, we evaluate available evidence linking excessive alcohol consumption with heart failure and dilated cardiomyopathy. Additionally, we discuss the clinical presentation, prognosis and treatment of ACM.

    Retail food environments are increasingly considered influential in determining dietary behaviours and health outcomes. We reviewed the available evidence on associations between community (type, availability and accessibility of food outlets) and consumer (product availability, prices, promotions and nutritional quality within stores) food environments and dietary outcomes in order to develop an evidence-based framework for monitoring the availability of healthy and unhealthy foods and non-alcoholic beverages in retail food environments. Current evidence is suggestive of an association between community and consumer food environments and dietary outcomes; however, substantial heterogeneity in study designs, methods and measurement tools makes it difficult to draw firm conclusions. The use of standardized tools to monitor local food environments within and across countries may help to validate this relationship. We propose a step-wise framework to monitor and benchmark community and consumer retail food environments that can be used to assess density of healthy and unhealthy food outlets; measure proximity of healthy and unhealthy food outlets to homes/schools; evaluate availability of healthy and unhealthy foods in-store; compare food environments over time and between regions and countries; evaluate compliance with local policies, guidelines or voluntary codes of practice; and determine the impact of changes to retail food environments on health outcomes, such as obesity.

    2016-06-01

    A study which is composed of computational simulation and experimental validation has been conducted for implementation of small, vane type geometries at freezer air outlets, similar to microvortex generators used in aircraft wings, in order to improve the heat transfer efficiency inside the freezer compartment by decreasing airside thermal resistance and improving the air distribution. Both simulation and experimental validation were performed in a loaded condition which was prepared according to `Household refrigerating appliances - characteristics and test methods - IEC 62552 [1]. Solutions for the incompressible K-epsilon (k-ɛ) turbulence model obtained for Bosch KDN 49 refrigerator freezer both with and without airshufflers at air outlets, which are similar to vane type microvortex generators with different geometric dimensions. The airshuffler dimensions were chosen with design of experiment (DOE) principles for finding the optimum geometry. The best combinations were tested according to cooling rate inside freezer compartment. Results were evaluated for feasibility of implementing of vortex generating surfaces (airshufflers) for cooling appliances.

  3. Spinal accessory neuropathy, droopy shoulder, and thoracic outlet syndrome.

    Al-Shekhlee, Amer; Katirji, Bashar

    2003-09-01

    Droopy shoulder has been proposed as a cause of thoracic outlet syndrome. Two patients developed manifestations of neurovascular compression upon arm abduction, associated with unilateral droopy shoulder and trapezius muscle weakness caused by iatrogenic spinal accessory neuropathies following cervical lymph node biopsies. The first patient developed a cold, numb hand with complete axillary artery occlusion when his arm was abducted to 90 degrees. The second patient complained of paresthesias in digits 4 and 5 of the right hand, worsened by elevation of the arm, with nerve conduction findings of right lower trunk plexopathy (low ulnar and medial antebrachial cutaneous sensory nerve action potentials). Spinal accessory nerve grafting (in the first patient) coupled with shoulder strengthening physical exercises in both patients resulted in gradual improvement of symptoms in 2 years. These two cases demonstrate that unilateral droopy shoulder secondary to trapezius muscle weakness may cause compression of the thoracic outlet structures.

    Full Text Available Gastric carcinoma is extremely rare in children representing only 0.05% of all gastrointestinal malignancies. Here, we report the first pediatric case of gastric cancer presenting with gastric outlet obstruction. Upper endoscopy revealed a markedly thickened antral mucosa occluding the pylorus and a clean base ulcer 1.5 cm × 2 cm at the lesser curvature of the stomach. The narrowed antrum and pylorus underwent balloon dilation, and biopsy from the antrum showed evidence of Helicobacter pylori gastritis. The biopsy taken from the edge of the gastric ulcer demonstrated signet-ring-cell type infiltrate consistent with gastric adenocarcinoma. At laparotomy, there were metastases to the liver, head of pancreas, and mesenteric lymph nodes. Therefore, the gastric carcinoma was deemed unresectable. The patient died few months after initiation of chemotherapy due to advanced malignancy. In conclusion, this case report underscores the possibility of gastric adenocarcinoma occurring in children and presenting with gastric outlet obstruction.

  5. Hydrological Modeling of the Jezero Crater Outlet-Forming Flood

    Abundant evidence exists for lakes on Mars both from orbital observations [e.g., 1-3] and in situ exploration [e.g., 4-5]. These lakes can be divided into two classes: those that were hydrologically closed, so their source valley(s) terminated at the basin [3], and those that were hydrologically open, where there was sufficient flow from inlet valley(s) to cause the lake to breach and form an outlet valley [2]. It is easier to be confident from orbital data alone that a standing body of water must have existed in open basins, because there is no other way for their perched outlet valleys to form. The majority of basins fed by valley networks, rather than by isolated inlet valleys, are open [6], with some important exceptions (e.g., Gale Crater). Jezero crater (Fig. 1) is one of the most well-studied open basin paleolakes on Mars, with a breach that re-mains well above the lowest part of the crater floor, and two sedimentary fans at its northwestern margin that are likely deltaic in origin [7-9]. CRISM observations of these sediments indicate they host a variety of alteration minerals [9-11], including smectite and carbonate, and both the mineralogy of the sediments and their settings suggest they have a strong potential for preserving organic materials [10]. As a result, Jezero is a strong candidate landing site for the Mars 2020 rover. Approximate formative discharges have been estimated for its well-preserved western fan (Q approximately 500m3/s) [7], but to our knowledge, no estimates for the dis-charges associated with formation and incision of its outlet valley have been presented. Indeed, only a few studies [e.g., 12-14] have attempted to reconstruct the formation of outlet breaches broadly similar to Jezero anywhere on Mars, despite the apparent commonality of basins with large outlets [e.g., 2]. The outlet valley formed as a dam breach when the lake overflowed. In such an event, the growth and incision of the breach is directly coupled to flood discharge

  6. Boundary conditions for free surface inlet and outlet problems

    KAUST Repository

    Taroni, M.

    2012-08-10

    We investigate and compare the boundary conditions that are to be applied to free-surface problems involving inlet and outlets of Newtonian fluid, typically found in coating processes. The flux of fluid is a priori known at an inlet, but unknown at an outlet, where it is governed by the local behaviour near the film-forming meniscus. In the limit of vanishing capillary number Ca it is well known that the flux scales with Ca 2/3, but this classical result is non-uniform as the contact angle approaches π. By examining this limit we find a solution that is uniformly valid for all contact angles. Furthermore, by considering the far-field behaviour of the free surface we show that there exists a critical capillary number above which the problem at an inlet becomes over-determined. The implications of this result for the modelling of coating flows are discussed. © 2012 Cambridge University Press.

    A turbofan gas turbine engine includes a forward fan section with a row of fan rotor blades, a core engine, and a fan bypass duct downstream of the forward fan section and radially outwardly of the core engine. The forward fan section has only a single stage of variable fan guide vanes which are variable fan outlet guide vanes downstream of the forward fan rotor blades. An exemplary embodiment of the engine includes an afterburner downstream of the fan bypass duct between the core engine and an exhaust nozzle. The variable fan outlet guide vanes are operable to pivot from a nominal OGV position at take-off to an open OGV position at a high flight Mach Number which may be in a range of between about 2.5-4+. Struts extend radially across a radially inwardly curved portion of a flowpath of the engine between the forward fan section and the core engine.

    High-pressure die casting such as thixocasting and rheocasting is an effective process in the manufacturing automotive parts. Following the recent trend in the automotive manufacturing technologies, the product design subject to the die casting becomes more and more complex. Simultaneously the injection speed is also designed to be very high to establish a short cycle-time. Thus, the requirement of the die design becomes more demanding than ever before. In some cases the product's shape can have multiple slender manifolds. In such cases, design of the inlet and outlet parts of the die is very important in the whole manufacturing process. The main issues required for the qualified products are to attain gentle and uniform flow of the molten liquid within the passages of the die. To satisfy such issues, the inlet cylinder ('bed cylinder' in this paper) must be as large as possible and simultaneously the outlet opening at the end of each passage must be as small as possible. However these in turn obviously bring additional manufacturing costs caused by re-melting of the bed cylinder and increased power due to the small outlet-openings. The purpose of this paper is to develop effective simulation methods of calculation for fluid flows in multiple columns, which mimic the actual complex design, and to get some useful information which can give some contributions to the die-casting industry. We have used a commercial code CFX in the numerical simulation. The primary parameter involved is the size of the bed cylinder. We will show how the very small opening of the outlet can be treated with the aid of the porous model provided in the code. To check the validity of the numerical results we have also conducted a simple experiment by using water.

    2007-01-01

    Formation of microstructure in homogeneous associated liquids is analysed through the density-density pair correlation functions, both in direct and reciprocal space, as well as an effective local one-body density function. This is illustrated through a molecular dynamics study of two neat alcohols, namely methanol and \\emph{tert}-butanol, which have a rich microstructure: chain-like molecular association for the former and micelle-like for the latter. The relation to hydrogen bonding interaction is demonstrated. The apparent failure to find microstructure in water -a stronger hydrogen bonding liquid- with the same tools, is discussed.

    2016-01-01

    Objectives Increasingly, English local authorities have encouraged the implementation of an intervention called ‘Reducing the Strength’ (RtS) whereby off-licences voluntarily stop selling inexpensive ‘super-strength’ (≥6.5% alcohol by volume (ABV)) beers and ciders. We conceptualised RtS as an event within a complex system in order to identify pathways by which the intervention may lead to intended and unintended consequences. Design A qualitative study including a focus group and semistructured interviews. Setting An inner-London local authority characterised by a high degree of residential mobility, high levels of social inequality and a large homeless population. Intervention piloted in three areas known for street drinking with a high alcohol outlet density. Participants Alcohol service professionals, homeless hostel employees, street-based services managers and hostel dwelling homeless alcohol consumers (n=30). Results Participants describe a range of potential substitution behaviours to circumvent alcohol availability restrictions including consuming different drinks, finding alternative shops, using drugs or committing crimes to purchase more expensive drinks. Service providers suggested the intervention delivered in this local authority missed opportunities to encourage engagement between the council, alcohol services, homeless hostels and off-licence stores. Some participants believed small-scale interventions such as RtS may facilitate new forms of engagement between public and private sector interests and contribute to long-term cultural changes around drinking, although they may also entrench the view that ‘problem drinking’ only occurs in certain population groups. Conclusions RtS may have limited individual-level health impacts if the target populations remain willing and able to consume alternative means of intoxication as a substitute for super-strength products. However, RtS may also lead to wider system changes not directly related

    An 89-year old female presented to us with symptoms of gastric outlet obstruction which appeared to be secondary to gastric volvulus on preoperative work-up. On laparoscopy the stomach was found to be incarcerated in a right-sided Morgagni hernia with surrounding adhesions. The hernia was reduced after dissecting the adhesions and the diaphragmatic defect was repaired using a biologic mesh onlay patch (Surgisis GOLD, Cook Biotech Inc.). Her postoperative recovery was uneventful and she was doing well at three months follow-up.

    Full Text Available The duodenum is a rare site for gastrointestinal lipoma with less than 230 cases reported in the literature. Although, peptic ulcer disease remains the most common benign cause of gastric outlet obstruction (GOO, duodenal lipomas remain a rare, but possible cause of GOO and could pose a diagnostic challenge, especially in countries where access to endoscopy and modern imaging techniques poses a challenge. The authors present a case of GOO in a 40-year-old male, secondary to a duodenal lipoma. It was successfully treated by a transduodenal resection through a midline laparotomy. The histology report confirmed it was a submucosal lipoma.

    This report summarizes the results of the experiments with a modified blowdown pipe outlet carried out with the PPOOLEX test facility designed and constructed at Lappeenranta University of Technology. Steam was blown into the dry well compartment and from there through a vertical DN200 blowdown pipe to the condensation pool. Four reference experiments with a straight pipe and ten with the Forsmark type collar were carried out. The main purpose of the experiment series was to study the effect of a blowdown pipe outlet collar design on loads caused by chugging phenomena (rapid condensation) while steam is discharged into the condensation pool. The PPOOLEX test facility is a closed stainless steel vessel divided into two compartments, dry well and wet well. During the experiments the initial temperature level of the condensation pool water was either 20-25 or 50-55 deg. C. The steam flow rate varied from 400 to 1200 g/s and the temperature of incoming steam from 142 to 185 deg. C. In the experiments with 20-25 deg. C pool water, even 10 times higher pressure pulses were measured inside the blowdown pipe in the case of the straight pipe than with the collar. In this respect, the collar design worked as planned and removed the high pressure spikes from the blowdown pipe. Meanwhile, there seemed to be no suppressing effect on the loads due to the collar in the pool side in this temperature range. Registered loads in the pool were approximately in the same range (or even a little higher) with the collar as with the straight pipe. In the experiments with 50-55 deg. C pool water no high pressure pulses were measured inside the blowdown pipe either with the straight pipe or with the collar. In this case, more of the suppressing effect is probably due to the warmer pool water than due to the modified pipe outlet. It has been observed already in the earlier experiments with a straight pipe in the POOLEX and PPOOLEX facilities that warm pool water has a diminishing effect on

    Thoracic outlet syndrome (TOS) is a condition arising from compression of the subclavian vessels and/or brachial plexus as the structures travel from the thoracic outlet to the axilla. Despite the significant pathology associated with TOS, there remains some general disagreement among experts on the specific anatomy, etiology, and pathophysiology of the condition, presumably because of the wide variation in symptoms that manifest in presenting patients, and because of lack of a definitive gold standard for diagnosis. Symptoms associated with TOS have traditionally been divided into vascular and neurogenic categories, a distinction based on the underlying structure(s) implicated. Of the two, neurogenic TOS (nTOS) is more common, and typically presents as compression of the brachial plexus; primarily, but not exclusively, involving its lower trunk. Vascular TOS (vTOS) usually involves compression of the vessel, most commonly the subclavian artery or vein, or is secondary to thrombus formation in the venous vasculature. Any anatomical anomaly in the thoracic outlet has the potential to predispose a patient to TOS. Common anomalies include variations in the insertion of the anterior scalene muscle (ASM) or scalenus minimus muscle, the presence of a cervical rib or of fibrous and muscular bands, variations in insertion of pectoralis minor, and the presence of neurovascular structures, which follow an atypical course. A common diagnostic technique for vTOS is duplex imaging, which has generally replaced more invasive angiographic techniques. In cases of suspected nTOS, electrophysiological nerve studies and ASM blocks provide guidance when screening for patients likely to benefit from surgical decompression of TOS. Surgeons generally agree that the transaxillary approach allows the greatest field of view for first rib excision to relieve compressed vessels. Alternatively, a supraclavicular approach is favored for scalenotomies when the ASM impinges on surrounding

    Epigastric hernia, a rare form of ventral abdominal hernia, accounts for 0.4 - 1.5% of all abdominal wall hernias. It usually occurs in middle - aged individuals and is rarely large enough to admit more than a small amount of extra-peritoneal fat. In this case report, we present a 64 years old woman with 6 days history of sudden onset of painful epigastric swelling associated with acute gastric outlet obstruction. We did not find a previous report of a similar case in the medical literature.

    Full Text Available Abstract Background Hyperplastic polyps are the most common polypoid lesions of the stomach. Rarely, they cause gastric outlet obstruction by prolapsing through the pyloric channel, when they arise in the prepyloric antrum. Case presentation A 62-year-old woman presented with intermittent nausea and vomiting of 4 months duration. Upper gastrointestinal endoscopy revealed a 30 mm prepyloric sessile polyp causing intermittent gastric outlet obstruction. Following submucosal injection of diluted adrenaline solution, the polyp was removed with a snare. Multiple biopsies were taken from the greater curvature of the antrum and the corpus. Rapid urease test for Helicobacter pylori yielded a negative result. Histopathologic examination showed a hyperplastic polyp without any evidence of malignancy. Biopsies of the antrum and the corpus revealed gastritis with neither atrophic changes nor Helicobacter pylori infection. Follow-up endoscopy after a 12-week course of proton pomp inhibitor therapy showed a complete healing without any remnant tissue at the polypectomy site. The patient has been symptom-free during 8 months of follow-up. Conclusions Symptomatic gastric polyps should be removed preferentially when they are detected at the initial diagnostic endoscopy. Polypectomy not only provides tissue to determine the exact histopathologic type of the polyp, but also achieves radical treatment.

  3. Technologies for Upgrading Light Water Reactor Outlet Temperature

    Nuclear energy could potentially be utilized in hybrid energy systems to produce synthetic fuels and feedstocks from indigenous carbon sources such as coal and biomass. First generation nuclear hybrid energy system (NHES) technology will most likely be based on conventional light water reactors (LWRs). However, these LWRs provide thermal energy at temperatures of approximately 300°C, while the desired temperatures for many chemical processes are much higher. In order to realize the benefits of nuclear hybrid energy systems with the current LWR reactor fleets, selection and development of a complimentary temperature upgrading technology is necessary. This paper provides an initial assessment of technologies that may be well suited toward LWR outlet temperature upgrading for powering elevated temperature industrial and chemical processes during periods of off-peak power demand. Chemical heat transformers (CHTs) are a technology with the potential to meet LWR temperature upgrading requirements for NHESs. CHTs utilize chemical heat of reaction to change the temperature at which selected heat sources supply or consume thermal energy. CHTs could directly utilize LWR heat output without intermediate mechanical or electrical power conversion operations and the associated thermodynamic losses. CHT thermal characteristics are determined by selection of the chemical working pair and operating conditions. This paper discusses the chemical working pairs applicable to LWR outlet temperature upgrading and the CHT operating conditions required for providing process heat in NHES applications.

  4. Methodological Approaches to Locating Outlets of the Franchise Retail Network

    Full Text Available Methodical approaches to selecting strategic areas of managing the future location of franchise retail network outlets are presented. The main stages in the assessment of strategic areas of managing the future location of franchise retail network outlets have been determined and the evaluation criteria have been suggested. Since such selection requires consideration of a variety of indicators and directions of the assessment, the author proposes a scale of evaluation, which allows generalizing and organizing the research data and calculations of the previous stages of the analysis. The most important criteria and sequence of the selection of the potential franchisees for the franchise retail network have been identified, the technique for their evaluation has been proposed. The use of the suggested methodological approaches will allow the franchiser making sound decisions on the selection of potential target markets, minimizing expenditures of time and efforts on the selection of franchisees and hence optimizing the process of development of the franchise retail network, which will contribute to the formation of its structure.

  5. TRICHOBEZOAR WITH GASTRIC OUTLET OBSTRUCTION: A CASE REPORT

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available Trichobezoar is collection of hairs forming a conglomerated mass. It is a very rare entity mimicking other common causes of gastric outlet obstruction. It is classically seen in adolescent females usually with psychiatric disturbances. Stomach is the most common site of occurrence. Occasionally, it may extend into small intestine (Rapunzel syndrome. Patients present with nonspecific symptoms such as loss of appetite, early satiety and vomiting. It may present as failure to thrive in small children. Diagnosis is frequently delayed due to paucity of symptoms. It is noticed as a slowly growing lump but occasionally may present with complications such as perforation, intestinal obstruction and pancreatitis. Abdominal ultrasonography is inconclusive and upper gastrointestinal endoscopy confirms the diagnosis. Laparotomy and extraction is the standard of treatment in spite of many new minimally invasive techniques. This is a case of gastric trichobezoar in a 16-year-old girl who presented with gastric outlet obstruction, which was successfully removed surgically. Recurrences are frequent due to associated psychiatric disturbances, hence psychiatric counselling must form an integral part of treatment.

    Gastric polyps are often an incidental finding on upper gastrointestinal endoscopy, with an incidence up to 5%. The majority of gastric polyps are asymptomatic, occurring secondary to inflammation. Prior reviews discussed Helicobacter pylori (H pylori)-associated singular gastric polyposis; however, we present a rare and unusual case of recurrent multiple benign gastric polyposis post H pylori eradication resulting in intermittent gastric outlet obstruction. A 70-year-old independent male, Chinese in ethnicity, with a background of diabetes mellitus, hypertension, and a simple renal cyst presented with a combination of melena, anemia, and intermittent vomiting of partially digested food after meals. Initial gastroscopy was positive for H pylori; thus he was treated with H pylori eradication and proton pump inhibitors. Serial gastroscopy demonstrated multiple sessile gastric antral polyps, the largest measuring 4 cm. Histopathologic examination confirmed a benign hyperplastic lesion. Computed tomography identified a pyloric mass with absent surrounding infiltration or metastasis. A distal gastrectomy was performed, whereby multiple small pyloric polyps were found, the largest prolapsing into the pyloric opening, thus explaining the intermittent nature of gastric outlet obstruction. Such polyps often develop from gastric ulcers and, if left untreated, may undergo neoplasia to form malignant cells. A distal gastrectomy was an effective choice of treatment, taking into account the polyp size, quantity, and potential for malignancy as opposed to an endoscopic approach, which may not guarantee a complete removal of safer margins and depth. Therefore, surgical excision is favorable for multiple large gastric polyps with risk of malignancy.

  7. Hydrogen-bond acidity of OH groups in various molecular environments (phenols, alcohols, steroid derivatives, and amino acids structures): experimental measurements and density functional theory calculations.

    The hydrogen-bond (H-bond) donating strengths of a series of 36 hydroxylic H-bond donors (HBDs) with N-methylpyrrolidinone have been measured in CCl4 solution by FTIR spectrometry. These data allow the definition of a H-bond acidity scale named pKAHY covering almost three pK units, corresponding to 16 kJ mol(-1). These results are supplemented by equilibrium constants determined in CH2Cl2 for one-third of the data set to study compounds showing a poor solubility in CCl4. A systematic comparison of these experimental results with theoretical data computed in the gas phase using DFT (density functional theory) calculations has also been carried out. Quantum electrostatic parameters appear to accurately describe the H-bond acidity of the hydroxyl group, whereas partial atomic charges according to the Merz-Singh-Kollman and CHelpG schemes are not suitable for this purpose. A substantial decrease of the H-bond acidity of the OH group is pointed out when the hydroxyl moiety is involved in intramolecular H-bond interactions. In such situations, the interactions are further characterized through AIM and NBO analyses, which respectively allow localizing the corresponding bond critical point and the quantification of a significant charge transfer from the available lone pair to the σ*OH antibonding orbital. Eventually, the H-bond ability of the hydroxyl groups of steroid derivatives and of lateral chains of amino acids are evaluated on the basis of experimental and/or theoretical data.

    The recent increase in the rate of mass loss from the Greenland Ice Sheet is primarily due to the acceleration and thinning of outlet glaciers along the coast. This acceleration is a dynamic response to the retreat of calving fronts, which leads to a loss in resistive stresses. These processes need to be included in ice sheet models in order to be able to accurately reproduce current trends in mass loss, and in the long term reduce the uncertainty in the contribution of ice sheets to sea level rise. Today, the vast majority of ice sheet models that include moving boundaries are one dimensional flow line and vertical flow band models, that are not adapted to the complex geometries of Greenland outlet glaciers, as they do not accurately capture changes in lateral stresses. Here, we use the level set method to track moving boundaries within a 2D plane view model of the Ice Sheet System Model (ISSM), and investigate the sensitivity of Store Glacier, in western Greenland, to the amount of melting occurring at its calving front. We explore different calving laws and obtain the best results with a new simple calving law adapted from von Mises yield criterion. We show that the ocean circulation near the front and the amount of runoff are able to trigger ice front advance and retreat depending on the amount of melting that they produce at the calving face, but the bed topography controls the stable positions of the ice front. The modeled calving front of Store Glacier, for which we have quality bed topography and sea floor bathymetry data, is particularly stable because of the presence of a large sill at the glacier terminus. If the ice front detaches from this stabilizing sill due to larger amounts of melting at the front or due to large calving events, the glacier front starts to retreat as the bed deepens inland, until it finds another stabilizing feature in the bed topography. The new bed topography maps based on mass conservation make it possible to model more

    Double outlet left ventricle (DOLV), even defined as origins or both great vessels from left ventricle, implies varieties of morphology in concern with loop pattern, location of ventricular septal defect, conotruncal anatomy, and presence or absence of pulmonary stenosis. With the improvement of surgical technique, corrective surgery of DOLV become possible, and preoperative diagnosis and determination of the accurate anatomical relationship between great vessels, ventricular septal defect, and ventricles is very important in surgical implication. Authors have recently experienced two cases of DOLV. The one is with subpulmonic conus, subpulmonic ventricular septal defect, patent ductus arteriosus, and preductal type coarctation of aorta. The other is with bilateral coni and subaortic ventricular septal defect. Loop patterns are [S, D, D]in both cases.

    We present a case of complete vaginal stenosis in a woman diagnosed with Sheehan's syndrome. The patient delivered at full-term 5 months prior, and experienced massive postpartum bleeding at that time. During evaluation of persistent amenorrhea, we found that her vaginal orifice was completely adhesive and obstructed. Prior to corrective surgery, we managed the patient with an oral contraceptive to induce uterine bleeding into the vaginal outflow tract. After three cycles of an oral contraceptive, we could confirm that there was no stenotic lesion in the vaginal cavity as a hematocolpos was created. Adhesiolysis with scar revision for the vaginal stenosis was successfully performed; it was found that the lesion was limited to only the distal part of the vaginal outlet. Complete vaginal stenosis in reproductive age women with hypopituitarism has not been reported. The artificial induction of hematometrocolpos before surgery was useful in determining the extent of the stenotic lesion, and assured safety.

    Tobacco products are sold in approximately 375,000 US retail outlets, including convenience stores and pharmacies, which often sell energy-dense, low-nutrient foods and beverages. The Food and Drug Administration’s (FDA’s) increased authority over tobacco product sales and marketing, combined with declining smoking rates, provides an opportunity to transition tobacco retailers toward healthier retail environments. Unfortunately, research into improving consumer retail environments is often conducted in isolation by researchers working in tobacco control, nutrition, and physical activity. Interdisciplinary efforts are needed to transform tobacco retailers from stores that are dependent on a declining product category, to the sale and promotion of healthful foods and creating environments conducive to active living. The objective of this article is to describe the potential for interdisciplinary efforts to transition retailers away from selling and promoting tobacco products and toward creating retail environments that promote healthful eating and active living.

    Gastric outlet obstruction (GOO) presenting beyond the newborn period is a relatively rare condition, when infantile hypertrophic pyloric stenosis (IHPS) is excluded. This report describes the clinical features, evaluation and management of 18 patients with GOO which was not caused by IHPS. The sex, age, and main presenting features were recorded on admission. Hemoglobin estimation, serum chemistry and blood gas analysis were also assessed in these patients. The diagnosis was confirmed with gastrointestinal barium, B ultrasound, gastroscopy, or at surgery. Some of them underwent gastroscopy with biopsy sampling for rapid urease test or histologic examination with Giemsa stains for Helicobacter pylori. Thirteen patients had peptic ulcer disease, of which six were successfully treated with medications. While the other seven needed operative management which included Heineke-Mikulicz pyloroplasty, gastroduodenostomy or gastrojejunostomy, respectively. All the patients who had Heineke-Mikulicz pyloroplasty or gastrojejunostomy developed bile reflux gastritis that could be alleviated with omeprazol. None of the patients developed dumping syndrome, failing to thrive, or anemia. Three children with antral diaphragm recovered without any complications by diaphragm excision with Heineke-Mikulicz pyloroplasty. The pylorus was compressed by fibrotic band in one 30-month boy, and he recovered uneventfully with Heineke-Mikulicz pyloroplasty during 10-year follow-up. Gastric outlet obstruction secondary to ingestion of sulfuric acid was noted in one patient, and he was successfully treated with gastroduodenostomy. Our data suggests that the satisfactory results could be expected in children with GOO with different therapeutic modalities based on the specific cause and degree of obstruction.

    Purpose Measuring activity spaces, places adolescents spend time, provides information about relations between contextual exposures and risk behaviors. We studied whether contextual exposures in adolescents’ activity spaces differ from contextual risks present in residential contexts and examined relationships between contextual exposures in activity spaces and alcohol/marijuana use. Methods Adolescents (N=18) aged 16–17 carried GPS-enabled smartphones for one week, with locations tracked. Activity spaces were created by connecting GPS points sequentially and adding buffers. Contextual exposure data (e.g., alcohol outlets) were connected to routes. Adolescents completed texts regarding behaviors. Results Adolescent activity spaces intersected 24.3 census tracts and contained 9 times more alcohol outlets than residential census tracts. Outlet exposure in activity spaces was related to drinking. Low SES exposure was related to marijuana use. Conclusions Findings suggest substantial differences between activity spaces and residential contexts, and suggest that activity spaces are relevant for adolescent risk behaviors. PMID:26206448

    Air-driven boosters are widely used to obtain high-pressure gas.Through analysis of the boosting process of an air-driven booster,the basic mathematical model of working processes can be set up.By selecting the appropriate reference values,the basic mathematical model is transformed to a dimensionless expression.Using MATLAB/Simulink for simulation and studying the booster experimentally,the dimensionless outlet flow characteristics of the booster were obtained and the simulation results agree well with the experimental results.Through analysis,it can be seen that the dimensionless outlet flow of the booster is mainly determined by the dimensionless input pressure of the driving chamber,the dimensionless outlet condition pressure of the booster and the dimensionless area of the piston in the driving chamber.The dimensionless average outlet flow becomes larger with an increasing dimensionless input pressure of the driving chamber,but it becomes smaller with an increase in the dimensionless outlet condition pressure of the booster.Especially when the dimensionless outlet condition pressure is approximately 1.4,the dimensionless average outlet flow reaches zero.With an increase in the dimensionless area of the piston in the driving chamber,the dimensionless average outlet flow increases and peaks at approximately 1.89,and after this peak,it starts to decrease.This research can be referred to in the design of air-driven boosters.

    Full Text Available From the standpoint of pathology, the term pyloric stenosis is usually inaccurate at least in adult patients, since the site of obstruction is rarely situated at the pylorus itself but is more often placed immediately proximal to the sphincter where the diagnosis of carcinoma is most probable or more dista lly in the duodenal bulb where the cause is almost invariably a duodenal ulcer. This study has been taken up to review the changes in presentation of gastric outlet obstruction in view of changing trends in the aetiology analysing the occurrence of benign and malignant causes, signs and symptoms, investigatory modalities, management and their results. The present study is an observational study a total of 50 cases were studied with Cicatrised duodenal ulcer and carcinoma pyloric antrum being the major cause s. Clinical profile, investigations and treatment outcomes were analysed. The majority of patients had malignant gastric outlet obstruction with 32[64%] patients presenting with Gastric cancer and 18[36%] patients presenting with cicatrised duodenal ulcer. In this study most patients were in the fifth and seventh decades of life. Men outnumbered women by 3: 1. The clinical presentation is not different from those in other studies with non - bilious vomiting being common to all the patients with dehydration. V isible gastric peristalsis and succussion splash were more prominent in Cicatrised Duodenal Ulcer. All cases were subjected to serum electrolyte estimation. Out of them 20 cases [40%] showed electrolyte imbalance barium meal, ultrasound abdomen pelvis and CT scan abdomen being the other investigating tools. Blood group ‘O’ was common in cicatrized duodenal ulcer patients [77.7%] followed by blood group ‘A’ [11.1%]. Upper GI endoscopy was done in all cases [100%]. 32[64%] cases had pyloric antral Carcinoma i n which 23 cases had fungating growth and the rest 9 had ulcerative growth and 18[36%] had cicatrized duodenal ulcer. 100

    The effect of coaxial, offset and extended inlet/outlet on the acoustic attenuation characteristics of circular expansion chambers are studied by the three-dimensional finite element method. The numerical results of transmission loss are compared with experiment results to verify the necessary of using three-dimensional methods. Maps of acoustic pressure level distribution inside of chambers and inlet/outlet ducts are given at a frequency to demonstrate the difference of acoustic wave propagation behavior caused by locations of inlet/outlet ducts. For the chambers of the same length, the chamber with extended inlet/outlet duct has higher attenuation ability than coaxial and offset inlet/outlet duct over middle frequencies.

    1978-01-01

    After formulating the definition of double outlet right ventricle (DORV) as the persistence origin of the trunco-conal structures from the right ventricle, 64 autopsy cases meeting this definition were reviewed. A wide spectrum of anatomic variations of DORV were found. A classification is proposed based upon the type of relationship between the great vessels and upon the presence and type of ventricular septal defect. Twenty-five cases had normally crossed great arteries (13 of which had pulmonic stenosis), nine cases had transposed vessels and 23 cases had a double muscular conus and a side-by-side arrangement of the great vessels in the frontal view, a relationship called "partial distortion" or atypical transposition. Seven cases had absent trunco-conal septum (common truncus). Only one case had intact ventricular septum. Anterior ventricular septal defect was found only in cases with partial distortion or common truncus. Angiographic and surgical correlations are presented. Because of their great heterogeneity, the need for detailed description of the anatomy of the individual case of DORV is emphasized.

    Thoracic outlet syndrome (TOS) is a well-known disorder, but many aspects of its pathology, including its definition, has been disputed. True neurogenic TOS (TN-TOS) is a rare but well-defined clinical condition. TN-TOS results from the compression of the C8/T1 roots (dominant for the T1 root) or the proximal lower trunk of the brachial plexus by a fibrous band. The band extends from the first rib to either the tip of an elongated C7 transverse process or a rudimentary cervical rib. The most common presenting symptoms of TN-TOS are insidious-onset atrophy and weakness of the intrinsic hand muscles, predominantly in the thenar eminence and radial digit flexors. Nerve conduction studies demonstrate pathognomonic findings: severely attenuated compound muscle action potential of the abductor pollicis brevis muscle, and usually, loss of the sensory nerve action potential of the medial antebrachial cutaneous nerve. Numbness and sensory loss are typically observed, mainly in the medial forearm, although they are usually mild, and may be absent in some patients. Severe pain or paresthesia proximal to the elbow is not observed. The classical concept of TOS underlie nonspecific neurogenic TOS. It has been primarily diagnosed using provocative maneuvers. However, there is controversy regarding its pathological conceptualization and existence, as objective evidence of the disease is still lacking.

  9. Surgical palliation of gastric outlet obstruction in advanced malignancy

    2016-01-01

    Gastric outlet obstruction (GOO) is a common problem associated with advanced malignancies of the upper gastrointestinal tract. Palliative treatment of patients’ symptoms who present with GOO is an important aspect of their care. Surgical palliation of malignancy is defined as a procedure performed with the intention of relieving symptoms caused by an advanced malignancy or improving quality of life. Palliative treatment for GOO includes operative (open and laparoscopic gastrojejunostomy) and non-operative (endoscopic stenting) options. The performance status and medical condition of the patient, the extent of the cancer, the patients prognosis, the availability of a curative procedure, the natural history of symptoms of the disease (primary and secondary), the durability of the procedure, and the quality of life and life expectancy of the patient should always be considered when choosing treatment for any patient with advanced malignancy. Gastrojejunostomy appears to be associated with better long term symptom relief while stenting appears to be associated with lower immediate procedure related morbidity. PMID:27648158

    Combustion dynamics data were collected at the NASA Glenn Research Center's CE-5 flame tube test facility under combustor outlet choked conditions. Two 9-point Swirl-Venturi Lean Direct Injection (SV-LDI) configurations were tested in a rectangular cuboid combustor geometry. Combustion dynamic data were measured at different engine operational conditions up to inlet air pressure and temperature of 24.13 bar and 828 K, respectively. In this study, the effects of acoustic cavity resonance, precessing vortex core (PVC), and non-uniform thermal expansion on the dynamic noise spectrum are identified by comparing the dynamic data that collected at various combustor inlet conditions along with combustor geometric calculations. The results show that the acoustic cavity resonance noises were seen in the counter-rotating pilot configuration but not in the co-rotating pilot configuration. Dynamic pressure noise band at around 0.9 kHz was only detected at the P'41 location (9.8 cm after fuel injector face) but not at the P'42 location (29 cm after the fuel injector face); the amplitude of this noise band depended on the thermal expansion ratio (T4/T3). The noise band at around 1.8 kHz was found to depend on the inlet air pressure or the air density inside the combustor. The PVC frequency was not observed in these two configurations.

    Underage drinking among American youth is a growing public concern. However, while extensive research has identified individual level predictors of this phenomenon, few studies have theorized and tested the effect of structural social forces on children's and youths' alcohol consumption. In an attempt to address this gap, we study the effects of residential environments on children's and youths' underage drinking (while accounting for personality and familial processes). Integrating informal social control and opportunity explanations of deviance, we first suggest that while neighborhood collective efficacy prevents adolescents' underage drinking, individuals' access to local alcohol retail shops encourages such behavior. Focusing on the interactive effects of communal opportunities and controls, we then suggest that high presence of alcohol outlets and sales in the neighborhood is likely to increase youths' probability of alcohol consumption in the absence of communal mechanisms of informal social control. We test our theoretical model using the unprecedented data design available in the PHDCN. Results from a series of multilevel logit models with robust standard errors reveal partial support for our hypotheses; specifically, we find that alcohol sales in a given neighborhood increase adolescents' alcohol use. In addition, while the direct effect of collective efficacy is insignificantly related to children's and youths' alcohol consumption, our models suggest that it significantly attenuates the effect of local alcohol retailers and sales on underage drinking.

    Full Text Available Gastric outlet obstruction (GOO after esophagectomy is a morbid outcome and significantly hinders quality of life for end-stage esophageal cancer patients. In the pre-stent era, palliation consisted of chemotherapy, radiation, tumor ablation, or stricture dilation. In the current era, palliative stenting has emerged as an additional tool; however, migration and tumor ingrowth are ongoing challenges. To mitigate these challenges, we developed a novel, hybrid, stent-based approach for the palliative management of GOO. We present a patient with esophageal cancer diagnosed with recurrent, metastatic disease 1 year after esophagectomy. She developed dehydration and intractable emesis, which significantly interfered with her quality of life. For palliation, we dilated the stenosis and proceeded with our stent-based solution. Using a combined endoscopic and fluoroscopic approach, we placed a 12-mm silicone salivary bypass tube across the pylorus, where it kinked slightly because of local tumor biology. To bridge this defect and ensure luminal patency, we placed a nitinol tracheobronchial stent through the silicone stent. Clinically, the patient had immediate relief from her pre-operative symptoms and was discharged home on a liquid diet. In conclusion, GOO and malignant dysphagia after esophagectomy are significant challenges for patients with end-stage disease. Palliative stenting is a viable option, but migration and tumor ingrowth are common complications. The hybrid approach presented here provides a unique solution to these potential pitfalls. The flared silicone tube minimized the chance of migration and impaired tumor ingrowth. The nitinol stent aided with patency and overcame the challenges of the soft tube. This novel strategy achieved palliation, describing another endoscopic option in the treatment of malignant GOO.

    Background Food prepared away from home has become increasingly popular to U.S. families, and may contribute to obesity. Sales have been dominated by fast food outlets, where meals are purchased for dining away from home or in the home. Although national chain affiliated fast-food outlets are considered the main source for fast food, fast foods are increasingly available in convenience stores and supermarkets/grocery stores. In rural areas, these nontraditional fast-food outlets may provide most of the opportunities for procurement of fast foods. Methods Using all traditional and nontraditio nal fast-food outlets identified in six counties in rural Texas, the type and number of regular and healthiermenu options were surveyed using on-site observation in all food venues that were primarily fast food, supermarket/grocery store, and convenience store and compared with 2005 Dietary Guidelines. Results Traditional fast-food outlets represented 84 (41%) of the 205 opportunities for procurement of fast food; 109 (53.2%) were convenience stores and 12 (5.8%) supermarkets/grocery stores. Although a s imilar variety of regular breakfast and lunch/dinner entrées were available in traditional fast-food outlets and convenience stores, the variety of healthier breakfast and lunch/dinner entrées was significantly greater in fast food outlets. Compared with convenience stores, supermarkets/grocery stores provided a greater variety of regular and healthier entrées and lunch/dinner side dishes. Conclusion Convenience stores and supermarkets/grocery stores more than double the potential access to fast foods in this rural area than traditional fast-food outlets alone; however, traditional fast food outlets offer greater opportunity for healthier fast food options than convenience stores.

    Full Text Available Abstract Background In recent years supermarkets and fast food restaurants have been replacing those “wet markets” of independent vendors as the major food sources in urban China. Yet how these food outlets relate to children’s nutritional intake remains largely unexplored. Method Using a longitudinal survey of households and communities in China, this study examines the effect of the urban built food environment (density of wet markets, density of supermarkets, and density of fast food restaurants on children’s nutritional intake (daily caloric intake, daily carbohydrate intake, daily protein intake, and daily fat intake. Children aged 6–18 (n = 185 living in cities were followed from 2004 to 2006, and difference-in-difference models are used to address the potential issue of omitted variable bias. Results Results suggest that the density of wet markets, rather than that of supermarkets, positively predicts children’s four dimensions of nutritional intake. In the caloric intake model and the fat intake model, the positive effect of neighborhood wet market density on children’s nutritional intake is stronger with children from households of lower income. Conclusion With their cheaper prices and/or fresher food supply, wet markets are likely to contribute a substantial amount of nutritional intake for children living nearby, especially those in households with lower socioeconomic status. For health officials and urban planners, this study signals a sign of warning as wet markets are disappearing from urban China’s food environment.

    Full Text Available Giant bladder diverticula are rare causes of bladder outlet obstruction in children and have rarely been reported. [1] In this paper, we present three children with giant bladder diverticula who presented with bladder outlet obstruction within a year. Micturating cystourethrogram is important for investigating bladder outlet obstruction in children and was used to confirm the diagnosis in all the patients. The relationship between the diverticula and ureters varied, with the ureters running either through the wall of the diverticulum and opening directly into the bladder, or opening into the diverticulum. In one patient, there was a recurrence, which was excised successfully. Excision is important to reduce the risk of recurrence.

    This report summarizes the findings of the PIV measurement tests carried out in January - February 2013 with the scaled down PPOOLEX test facility at LUT. The main objective of the tests was to find out the operational limits of the PIV system regarding suitable test conditions and correct values of different adjustable PIV parameters. An additional objective was to gather CFD grade data for verification/validation of numerical models. Both water and steam injection tests were carried out. PIV measurements with cold water injection succeeded well. Raw images were of high quality, averaging over the whole measurement period could be done and flow fields close to the blowdown pipe outlet could be determined. In the warm water injection cases the obtained averaged velocity field images were harder to interpret, especially if the blowdown pipe was also filled with warm water in the beginning of the measurement period. The absolute values of the velocity vectors seemed to be smaller than in the cold water injection cases. With very small steam flow rates the steam/water interface was inside the blowdown pipe and quite stable in nature. The raw images were of good quality but due to some fluctuation in the velocity field averaging of the velocity images over the whole measured period couldn't be done. Condensation of steam in the vicinity of the pipe exit probably caused these fluctuations. A constant outflow was usually followed by a constant inflow towards the pipe exit. Vector field images corresponding to a certain phase of the test could be extracted and averaged but this would require a very careful analysis so that the images could be correctly categorized. With higher steam flow rates rapid condensation of large steam bubbles created small gas bubbles which were in front of the measurement area of the PIV system. They disturbed the measurements by reflecting laser light like seeding particles and therefore the raw images were of poor quality and they couldn

    Full Text Available Researchers and policy-makers are interested in the influence that food retailing around schools may have on child obesity risk. Most previous research comes from North America, uses data aggregated at the school-level and focuses on associations between fast food outlets and school obesity rates. This study examines associations between food retailing and BMI among a large sample of primary school students in Berkshire, England. By controlling for individual, school and home characteristics and stratifying results across the primary school years, we aimed to identify if the food environment around schools had an effect on BMI, independent of socio-economic variables.We measured the densities of fast food outlets and food stores found within schoolchildren's home and school environments using Geographic Information Systems (GIS and data from local councils. We linked these data to measures from the 2010/11 National Child Measurement Programme and used a cross-classified multi-level approach to examine associations between food retailing and BMI z-scores. Analyses were stratified among Reception (aged 4-5 and Year 6 (aged 10-11 students to measure associations across the primary school years.Our multilevel model had three levels to account for individual (n = 16,956, home neighbourhood (n = 664 and school (n = 268 factors. After controlling for confounders, there were no significant associations between retailing near schools and student BMI, but significant positive associations between fast food outlets in home neighbourhood and BMI z-scores. Year 6 students living in areas with the highest density of fast food outlets had an average BMI z-score that was 0.12 (95% CI: 0.04, 0.20 higher than those living in areas with none.We found little evidence to suggest that food retailing around schools influences student BMI. There is some evidence to suggest that fast food outlet densities in a child's home neighbourhood may have an effect on BMI

    We report a planar solenoid actuated valveless micropump with multiple inlet-outlet configurations. The self-priming characteristics of the multiple inlet-multiple outlet micropump are studied. The filling dynamics of the micropump chamber during start-up and the effects of fluid viscosity, voltage and frequency on the dynamics are investigated. Numerical simulations for multiple inlet-multiple outlet micropumps are carried out using fluid structure algorithm. With DI water and at 5.0 Vp-p, 20 Hz frequency, the two inlet-two outlet micropump provides a maximum flow rate of 336 μl min-1 and maximum back pressure of 441 Pa. Performance characteristics of the two inlet-two outlet micropump are studied for aqueous fluids of different viscosity. Transport of biological cell lines and diluted blood samples are demonstrated; the flow rate-frequency characteristics are studied. Viability of cells during pumping with multiple inlet multiple outlet configuration is also studied in this work, which shows 100% of cells are viable. Application of the proposed micropump for simultaneous pumping, mixing and distribution of fluids is demonstrated. The proposed integrated, standalone and portable micropump is suitable for drug delivery, lab-on-chip and micro-total-analysis applications.

  13. Assessment of uncertainty in suspended sediment load at constructed wetland inlet and outlet

    Science.gov (United States)

    Eskelinen, Riku; Ronkanen, Anna-Kaisa; Marttila, Hannu; Kløve, Bjørn

    2016-04-01

    The use of constructed wetlands (CWs) for reducing pollution from different industries and land uses is common practice globally. Different countries have approached monitoring of CWs performance in several ways. For example, authorities can have different requirements in the flow measurement and sampling frequencies depending of the nature of the pollutant load. Typically, the load remaining after CW purification is estimated through concentration and flow measurements. As taking water samples comes with a cost, samples are taken with long intervals which can increase the uncertainty in the estimated loads. In 2012, a large water quality dataset was collected from CW inlet and outlet containing daily or twice a day water quality samples spanning from March until October. By sub-sampling the collected data with 1, 2, 3, or 4 weeks intervals we estimated the uncertainty range related to the sparse sampling. The results show large uncertainty remaining even with weekly sampling which suggests that increasing the sampling density from once in two weeks to once a week is not probably worth as the costs related to sampling would double. A method based on the flow duration curve (FDC) of the CW for reducing the uncertainty was also tested. The method divides the observed FDC to four equal parts and finds the mean or median concentration for each flow category. The load is then calculated by multiplying the observed flow with the mean or median concentration with the appropriate flow category. The FDC method was able to decrease the uncertainty, but much still remained, especially when concentrations of the measured variable showed large variation as it is typical case if annual nutrient and sediment loads from different land uses are monitored. Generally, continuous sensor technology might be a feasible option for further reducing the uncertainty in load estimation.

    While the harmful effects of alcohol during pregnancy are well-established, the consequences of alcohol intake during lactation have been far less examined. We reviewed available data on the prevalence of alcohol intake during lactation, the influence of alcohol on breastfeeding......, the pharmacokinetics of alcohol in lactating women and nursing infants and the effects of alcohol intake on nursing infants. A systematic search was performed in PubMed from origin to May 2013, and 41 publications were included in the review. Approximately half of all lactating women in Western countries consume...... alcohol while breastfeeding. Alcohol intake inhibits the milk ejection reflex, causing a temporary decrease in milk yield. The alcohol concentrations in breast milk closely resemble those in maternal blood. The amount of alcohol presented to nursing infants through breast milk is approximately 5...

    Social media and electronic news media activity are an important source of information for the general public. Yet, there is a dearth of research exploring the use of Twitter and electronic news outlets during significant worldly events such as the recent Ebola Virus scare. The purpose of this article is to investigate the use of Twitter and electronic news media outlets in communicating Ebola Virus information. A cross-sectional survey of Twitter data and Google News Trend data from 30 September till 29 October, 2014 was conducted. Between 30 September and 29 October, there were approximately 26 million tweets (25,925,152) that contained the word Ebola. The highest number of correlated activity for Twitter and electronic news outlets occurred on 16 October 2014. Other important peaks in Twitter data occurred on 1 October, 6 October, 8 October, and 12 October, 2014. The main influencers of the Twitter feeds were news media outlets. The study reveals a relationship between electronic news media publishing and Twitter activity around significant events such as Ebola. Healthcare organizations should take advantage of the relationship between electronic news media and trending events on social media sites such as Twitter and should work on developing social media campaigns in co-operation with leading electronic news media outlets (e.g. CNN, Yahoo, Reuters) that can have an influence on social media activity.

    Based on the thermal and velocity layer’s theory,the experimental setup was established on large space atrium under nozzle outlet. A series of winter experiments were accomplished and the following conclusions could be drawn. At the sunny day of winter in Shanghai,the thermal and velocity layer are similar. The height of the both layer is 10-30 mm,and the temperature gratitude is 5-10 ℃ /m. Decreasing the angle of the nozzle outlet can increase the layer height dramatically. The maximum temperature difference of the occupant zone has relation with the angle of the nozzle outlet. The less the angle of the nozzle outlet is set,the greater the temperature difference is. The occupant temperature differences at these angles of the nozzle outlet are 5.1-4.4 ℃. The velocity of the wind is 0.02 and 0.17 m/s and they can accord with design demand. So,it can decrease the temperature gratitude by about 30% and it can save 10%-15% energy consumption.

    Objectives. To examine the association of school sociodemographic characteristics with tobacco outlet and fast-food restaurant availability near schools in a national study. Methods. Business lists and data from the National Center for Education Statistics were used to calculate the numbers of tobacco outlets and fast-food restaurants within 800 meters of public schools in 97 US counties. Results. More than 50% of schools with a majority of Hispanic students had both a fast-food restaurant and tobacco outlet nearby, compared with 21% of schools with a majority of White students. In adjusted models, each 10% increase in the number of low-income and Hispanic students enrolled in a school led to a 3% to 5% increase in the odds of the school having both a fast-food restaurant and a tobacco outlet nearby. Conclusions. Low-income and Hispanic students are disproportionately exposed to both tobacco outlets and fast-food restaurants near their schools. Easy access to tobacco products and fast food may influence youth smoking initiation and contribute to poor dietary intake. PMID:27459453

    Alcohol drinking habits and alcoholism are partly genetically determined. Alcohol is degraded primarily by alcohol dehydrogenase (ADH) wherein genetic variation that affects the rate of alcohol degradation is found in ADH1B and ADH1C. It is biologically plausible that these variations may be associated with alcohol drinking habits and alcoholism. By genotyping 9080 white men and women from the general population, we found that men and women with ADH1B slow vs fast alcohol degradation drank more alcohol and had a higher risk of everyday drinking, heavy drinking, excessive drinking and of alcoholism. For example, the weekly alcohol intake was 9.8 drinks (95% confidence interval (CI): 9.1-11) among men with the ADH1B.1/1 genotype compared to 7.5 drinks (95% CI: 6.4-8.7) among men with the ADH1B.1/2 genotype, and the odds ratio (OR) for heavy drinking was 3.1 (95% CI: 1.7-5.7) among men with the ADH1B.1/1 genotype compared to men with the ADH1B.1/2 genotype. Furthermore, individuals with ADH1C slow vs fast alcohol degradation had a higher risk of heavy and excessive drinking. For example, the OR for heavy drinking was 1.4 (95% CI: 1.1-1.8) among men with the ADH1C.1/2 genotype and 1.4 (95% CI: 1.0-1.9) among men with the ADH1B.2/2 genotype, compared with men with the ADH1C.1/1 genotype. Results for ADH1B and ADH1C genotypes among men and women were similar. Finally, because slow ADH1B alcohol degradation is found in more than 90% of the white population compared to less than 10% of East Asians, the population attributable risk of heavy drinking and alcoholism by ADH1B.1/1 genotype was 67 and 62% among the white population compared with 9 and 24% among the East Asian population.

    A Morgagni hernia is a rare diaphragmatic hernia which develops through a congenital defect in the retrosternal area, usually on the right hand side. Because of its congenital aetiology, Morgagni hernias are rarely considered in the differential diagnosis of gastric outlet obstruction symptoms in adults. We present a patient with an incarcerated Morgagni hernia who presented with gastric outlet obstruction. A 77-year-old woman presented with symptoms and signs of gastric outlet obstruction, dehydration and acute renal impairment. She was treated by fluid resuscitation and nasogastric tube insertion. Radiological imaging showed a Morgagni hernia containing stomach, omentum and colon. This was treated surgically via an abdominal approach and the defect was closed with mesh. The patient recovered well from this procedure and was discharged. We discuss the anatomy, clinical presentation and surgical treatment of this rare diaphragmatic hernia to raise awareness among surgeons and surgical trainees.

    Morgagni hernia is the rarest of all congenital diaphragmatic hernias, first described in 1769. It is rarely symptomatic and found on routine radiological examinations for other conditions. Gastric outlet obstruction in adults with Morgagni Hernia is exceedingly rare. An 80-year-old man was taken to the operating room with a diagnosis of Morgagni hernia with gastric outlet obstruction. An upper midline laparotomy was performed, and the incarcerated pylorus and antrum of the stomach reduced with primary closure of the defect. Postoperative period was uneventful, and the patient was discharged on the sixth postoperative day. Morgagni hernia is exceedingly rare in adults and may present with gastric outlet obstruction in the emergency room. This clinical entity should be kept in mind while evaluating the patient, and early surgical intervention should be initiated.

    This paper presents an experimental study result of flow field of a dual-channel burner. In order to solve the ubiquitous problem of bad rigidity of jets in dual-channel burners, wedges with different arrangements and structural parameters were added to different positions at the outlet of the burners. Laser Particle Image Velocimetry (PIV) was used in this study to measure the flow field to investigate influence of the wedges on flow field of the dual-channel burner. Experimental study shows that fixing wedges at both right and left sides of the burner's outlet can increase the intensity of recirculation without changing the size of the recirculation zone and enhance the rigidity of jets via increasing speed of the two primary air jets at the outlet.

The heat transfer is quite complex because it takes place both directly through the contact points between bulb and pipe and indirectly through the mounting strap The TXV has to react to temperature changes at the evaporator outlet. Therefore, the dynamic behavior...... of the valve (and thereby the whole refrigeration system) depends greatly on the heat transfer between the evaporator outlet tube and the charge in the bulb. In this paper a model for the overall heat transfer between the pipe and the charge is presented. Geometrical data and material properties have been kept...... been found to predict the time constant for the temperature development in the bulb within 1-10 %. Furthermore it has been found that app. 20% of the heat transfer takes place trough the mounting strap....

    2013-10-01

    Participation from the business community is critical to effectively addressing the problem of obesity. This commentary builds on the recent Institute of Medicine report - Accelerating Progress in Obesity Prevention - which calls for participation from the business community, particularly food outlets, to effectively address the problem of obesity. This commentary specifically discusses the importance of collecting information on fiscal-related outcomes (e.g., revenue) in order to better engage local food outlets in obesity prevention activities in the community. The routine collection of fiscal indicators in obesity prevention studies is critical so that the argument for more involvement from local food outlets, particularly for those interventions which are revenue positive or revenue neutral, can be more persuasively made.

    Thoracic outlet syndrome involves more than just local neurovascular compression. Myofascial release treatments and stretching exercises may be only partially or temporarily successful unless all related components of somatic dysfunction, including craniosacral mechanisms, are addressed. Structural and postural abnormalities in the frontal plane, as with a short leg, and in the sagittal plane, such as lumbopelvic imbalances, as well as neural involvement all contribute to thoracic outlet syndrome symptoms. Once segmental restrictions are treated and symptoms diminish, postural correction and strengthening exercises may be initiated. Osteopathic diagnosis and treatment of the local, regional, and remote structural problems is necessary for optimal treatment of thoracic outlet syndrome and the maintenance of a symptom-free status.

    2013-01-01

    Full Text Available Bangladesh is believed to be a low HIV prevalent country although the potentiality of spreading HIV remains high because of several contributing factors. There is many sex –workers active with highest sexual contacts and partner exchange but low condom use by both sex workers and their clients expedite the prevalence significantly. There is a sizable population of men who have sex with men and hijra –those who usually do not use condom and consequently high rates of sexually transmitted infections (STIs prevailed in them. Stigma and discrimination against most at risk populations (MARPs is the biggest hurdle to bring them under prevention services against HIV/AIDS in Bangladesh. Therefore Bangladesh is vulnerable to HIV/STI. Condom outlet is a gypsy platform in where most at risk peoples are getting free access to condom at their will. The paper attempts to identify the underlying role of community condom outlet for the prevention of HIV/STI in Bangladesh. Condom outlets are working as an inseparable volunteer under outreach service of HIV/STI prevention project through diversified role as monitor of peer educators, knowledge store of HIV/STI, conflict solver, shelter of peer, outreach worker as well as project staff to fight against HIV/AIDS in Bangladesh. The theoretical approach and literature review of this study provides an understanding of community condom outlet. The researchers try to answer the questions of who the community condom outlets are, what their lifestyle in preventing HIV / STI and how condom outlet are working with community for preventing HIV and STI.

  8. Statistical Approaches Used to Assess the Equity of Access to Food Outlets: A Systematic Review

    Full Text Available BackgroundInequalities in eating behaviours are often linked to the types of food retailers accessible in neighbourhood environments. Numerous studies have aimed to identify if access to healthy and unhealthy food retailers is socioeconomically patterned across neighbourhoods, and thus a potential risk factor for dietary inequalities. Existing reviews have examined differences between methodologies, particularly focussing on neighbourhood and food outlet access measure definitions. However, no review has informatively discussed the suitability of the statistical methodologies employed; a key issue determining the validity of study findings. Our aim was to examine the suitability of statistical approaches adopted in these analyses.MethodsSearches were conducted for articles published from 2000-2014. Eligible studies included objective measures of the neighbourhood food environment and neighbourhood-level socio-economic status, with a statistical analysis of the association between food outlet access and socio-economic status.ResultsFifty-four papers were included. Outlet accessibility was typically defined as the distance to the nearest outlet from the neighbourhood centroid, or as the number of food outlets within a neighbourhood (or buffer. To assess if these measures were linked to neighbourhood disadvantage, common statistical methods included ANOVA, correlation, and Poisson or negative binomial regression. Although all studies involved spatial data, few considered spatial analysis techniques or spatial autocorrelation.ConclusionsWith advances in GIS software, sophisticated measures of neighbourhood outlet accessibility can be considered. However, approaches to statistical analysis often appear less sophisticated. Care should be taken to consider assumptions underlying the analysis and the possibility of spatially correlated residuals which could affect the results.

  9. Alcohol Dependence and Alcoholic Liver Disease

    Full Text Available Alcohol dependence is a disabling condition that has a high prevalence, but in Europe only a small fraction of the people diagnosed with alcohol abuse and dependence are treated, representing the widest treatment gap, as compared with other mental disorders. Early diagnosis and monitoring of alcoholic liver disease (ALD is still insufficiently solved. Although ALD is the most common cause for liver disease in the Western world, it largely remains underestimated and underdiagnosed for many reasons. The recent introduction of non-invasive elastographic techniques such as transient elastography (TE has significantly improved the early diagnosis of alcoholic liver cirrhosis (ALC. As demonstrated in the literature, inflammation-associated liver stiffness (LS rapidly decreases during alcohol detoxification, and is also directly correlated to change in LS in both abstinent and relapsing patients. Newly published data show that LS could be used to monitor and validate hepatoprotective effects during nalmefene usage. Nalmefene is an opioid system modulator that diminishes the reinforcing effects of alcohol, helping the patient to reduce drinking. Three randomised, multicentre, double-blind, placebo-controlled, parallelgroup Phase III studies were designed to assess the efficacy and safety of nalmefene in reducing alcohol consumption. Patients with a high or very high drinking risk level (DRL at baseline and randomisation show a clinically significant effect from nalmefene treatment, which is generally well tolerated. Moreover, reduced alcohol consumption supported by nalmefene in combination with psychosocial support may indeed help to reduce the alcohol-related burden and the large treatment gap.

    The eclipsed form arrangement and march-past method of water intake-outlet arrangements in power plants were researched by 3-D numerical simulation based on the k-ε two-equation turbulence model. Firstly, the flowing characteristics of eclipsed form arrangement were analyzed and the effects of some main factors on inlet temperature were investigated. The simulation results are basically in agreement with those of the previous experiments. Then, by comparing the inlet temperature of the above two intake-outlet methods, the superiority and its existent conditions of the eclipsed form were examined.

    2005-05-01

    The possibility of enzymatic pH oscillations is investigated for a CSTR with an outlet regulator. A linear stability analysis shows that no oscillation is possible in a CSTR without the regulator, using a proton-producing pH-dependent enzymatic reaction. However, self-sustained oscillations are found to occur in a CSTR, where the discharge of substrate is regulated at the outlet. The regions of oscillations in the parameter space are determined using a hydrolysis of N-α-benzoyl- L-arginine ethyl ester with papain. It is found that the region is quite large only when the substrate concentration in the outflow is kept at zero.

  14. Impacts of international trade, services and investment treaties on alcohol regulation.

    Science.gov (United States)

    Grieshaber-Otto, J; Sinclair, S; Schacter, N

    2000-12-01

    There is an underlying incompatibility between government efforts to minimize the harm associated with alcohol, particularly by regulating its supply, and international commercial treaties that promote the freer flow of goods, services and investment. These treaties have already forced changes to many government measures affecting alcohol availability and control, primarily by constraining the activities of government alcohol monopolies and by altering taxation regimes. The North American Free Trade Agreement and the World Trade Organization agreements open new avenues for challenges against alcohol control measures. Some of these agreements extend beyond trade, border measures and differential taxation and allow challenges that intrude into areas of non-discriminatory domestic regulation affecting market access, intellectual property, investment and services. Effective protection from these agreements for vital public health measures has rarely been obtained, although it is increasingly essential. The WTO "services" agreement, basically unknown to the public, is currently being re-negotiated and poses the gravest new challenge to policies designed to influence patterns of alcohol use and minimize alcohol-related harm. In future, these international agreements will probably affect adversely those alcohol approaches considered to be the most effective or promising. These include: maintaining effective state monopolies, restricting the number and locations of retail outlets, taxing and regulating beverages according to alcohol strength, restricting commercial advertising, and maintaining and enhancing public alcohol education and treatment programs. These effects can, in turn, be expected to increase the availability and access to alcohol, to lower alcohol taxes, and to increase advertising and promotion, resulting in increased alcohol consumption and associated health problems. Until more balanced international rules are developed, the challenge facing alcohol

    Full Text Available Anthocyanins red pigments that give color a wide range of fruits, berries and flowers. In the food industry it is widely known as a dye a food additive E163. To extract from natural vegetable raw materials traditionally used ethanol or acidified water, but in same technologies it’s unacceptable. In order to expand the use of anthocyanins as colorants and antioxidants were explored extracting pigments alcohols with different structures of the carbon skeleton, and the position and number of hydroxyl groups. For the isolation anthocyanins raw materials were extracted sequentially twice with t = 60 C for 1.5 hours. The evaluation was performed using extracts of classical spectrophotometric methods and modern express chromaticity. Color black currant extracts depends on the length of the carbon skeleton and position of the hydroxyl group, with the alcohols of normal structure have higher alcohols compared to the isomeric structure of the optical density and index of the red color component. This is due to the different ability to form hydrogen bonds when allocating anthocyanins and other intermolecular interactions. During storage blackcurrant extracts are significant structural changes recoverable pigments, which leads to a significant change in color. In this variation, the stronger the higher the length of the carbon skeleton and branched molecules extractant. Extraction polyols (ethyleneglycol, glycerol are less effective than the corresponding monohydric alcohols. However these extracts saved significantly higher because of their reducing ability at interacting with polyphenolic compounds.

    Full Text Available The author briefly interprets the research – results, referring to the phenomenon of children of alcoholics, especially the psychological and psychopathological characteristics of children of alcoholics in adolescence and young adulthood. The author presents a screening study of adolescents. The sample contains 200 high school students at age 18. The aim of the survey was to discover the relationship between alcohol consumption of parents, PTSD - related psychopathological symptoms and reported life quality of their children. The study confirmed the hypothesis about a substantial correlation between high alcohol consumption of parents, higher psychopathological symptom - expression and lower reported life quality score of their children. Higher PTSD-related symptomatology in children of alcoholics is probably resulted by home violence, which is very often present in family of alcoholics. The article also evaluated the results regarding suicide ideation of children of alcoholics, which is definitely more frequent and more intense than in their peers living in non alcohol – dependent families.

    Alcohol consumption and alcohol-attributable burden of disease in Africa are expected to rise in the near future, yet. increasing alcohol-related harm receives little attention from policymakers and from the population in general. Even where new legislation is proposed it is rarely enacted into law. Being at the center of social and cultural activities in many countries, alcohol's negative role in society and contribution to countries' burden of disease are rarely questioned. After the momentum created by the adoption in 2010 of the WHO Global Strategy and the WHO Regional Strategy (for Africa) to Reduce the Harmful Use of Alcohol, and the WHO Global Action Plan for the Prevention and Control of Non-Communicable Diseases, in 2013, little seems to have been done to address the increasing use of alcohol, its associated burden and the new challenges that derive from the growing influence of the alcohol industry in Africa. In this review, we argue that to have a positive impact on the health of African populations, action addressing specific features of alcohol policy in the continent is needed, namely focusing on particularities linked to alcohol availability, like unrecorded and illicit production, outlet licensing, the expansion of formal production, marketing initiatives and taxation policies.

    The effects of carrier gas conditions on the concentration of ethanol by ultrasonic atomization are examined. With increasing height from vessel bottom to gas inlet and outlet, the ethanol content in the accompanied liquid increases and the flow rate of alcohol decreases. The ethanol content in the accompanied liquid becomes lower as the gas velocity becomes higher. The attachment of a demister is effective for the increase of the content in the accompanied liquid.

    Full Text Available Gastric outlet obstruction is defined as a clinical and patho - physiological consequence of any disease process that produces a mechanical impediment to gastric emptying which may be extrinsic or intrinsic. Gastric outlet obstruction can be a diagnostic and treatment dilemma. Endoscopy of upper gastrointestinal tract has been a sensitive and specific investigation to study the status of gastric outlet - the pylorus and has enabled early detection of lesions of both stomach a nd duodenum. We undertook a prospective clinical study regarding incidence, etiology, investigation and management of cases of Gastric outlet obstruction in adults in a period of three years. In our study the m ost common cause of GOO is Carcinoma stomach a ntral region 46.6% , duodenal ulcer 33.3% , corrosive acid ingestion sequel 8.3%, peri ampullary carcinoma 6.6%, Ca pancreas 3.3%% , cholangio Carcinoma 1.6%.

    Thoracic outlet syndrome (TOS) is a group of disorders all having in common compression at the thoracic outlet. Three structures are at risk: the brachial plexus, the subclavian vein, and the subclavian artery, producing neurogenic (NTOS), venous (VTOS), and arterial (ATOS) thoracic outlet syndromes, respectively. Each of these three are separate entities, though they can coexist and possibly overlap. The treatment of NTOS, in particular, has been hampered by lack of data, which in turn is the result of inconsistent definitions and diagnosis, uncertainty with regard to treatment options, and lack of consistent outcome measures. The Committee has defined NTOS as being present when three of the following four criteria are present: signs and symptoms of pathology occurring at the thoracic outlet (pain and/or tenderness), signs and symptoms of nerve compression (distal neurologic changes, often worse with arms overhead or dangling), absence of other pathology potentially explaining the symptoms, and a positive response to a properly performed scalene muscle test injection. Reporting standards for workup, treatment, and assessment of results are presented, as are reporting standards for all phases of VTOS and ATOS. The overall goal is to produce consistency in diagnosis, description of treatment, and assessment of results, in turn then allowing more valuable data to be presented.

    Graphical abstract: -- Highlights: •Multiplexed detection for liquid chromatography. •‘Parallel segmented outlet flow’ distributes inner and outer portions of the analyte zone. •Three detectors were used simultaneously for the determination of opiate alkaloids. -- Abstract: We describe a new approach to multiplex detection for HPLC, exploiting parallel segmented outlet flow – a new column technology that provides pressure-regulated control of eluate flow through multiple outlet channels, which minimises the additional dead volume associated with conventional post-column flow splitting. Using three detectors: one UV-absorbance and two chemiluminescence systems (tris(2,2′-bipyridine)ruthenium(III) and permanganate), we examine the relative responses for six opium poppy (Papaver somniferum) alkaloids under conventional and multiplexed conditions, where approximately 30% of the eluate was distributed to each detector and the remaining solution directed to a collection vessel. The parallel segmented outlet flow mode of operation offers advantages in terms of solvent consumption, waste generation, total analysis time and solute band volume when applying multiple detectors to HPLC, but the manner in which each detection system is influenced by changes in solute concentration and solution flow rates must be carefully considered.

    In stacked buildings large pressure differences can occur when appliances with individual air supply pipes are connected to a communal outlet. This can be prevented by using a so-called bypass system, which couples the air supply pipe directly to the combustion gases outlet. In case of overpressure on the air supply of an appliance, air will be transported to the combustion gases outlet around the appliance. Descriptions are given of two GASTEC-developed indoor systems: a mechanical bypass system and an aerodynamic bypass system. The aerodynamic system has been optimized for a retrofitting boiler project in Assen, Netherlands. In this project a communal heating system has been replaced by individual central heating boilers. The appliance used was a high-efficiency boiler, the NEFIT Turbo 21. The disadvantage of the mechanical bypass system is one of the moving parts: the valve, which is too sensitive for pollution and failures. Large pressure difference reductions are possible by means of the aerodynamic bypass system. Recirculation can be prevented by high-speed injection of the combustion gases in the combustion gases outlet. 13 figs., 26 tabs., 2 appendices, 2 refs.

    2011-08-01

    We observed dissolved nitrogen retention in vegetated bioretention mesocosms using different media with varying hydraulic conductivities. Elevated outlets were installed to regulate hydraulic response, with one treatment left free draining. The treatments (three replicates each) were loaded weekly with 50 cm of effluent averaging 2.47 mg/L nitrogen oxides (NOx) and 4.67 mg/L total nitrogen for 1 year. The NOx and total nitrogen retention by the outlet regulated treatments was significantly greater than the unregulated treatment. The systems then were dosed 6 times with 53 cm of synthetic stormwater averaging 0.77 mg/ L NOx and 1.46 mg/L total nitrogen, applied over 90 minutes. The outlet regulated treatment retained 68% NOx and 60% total nitrogen, while the corresponding free draining treatment retained 25% NOx and 27% total nitrogen. Over the following winter, the outlet regulated treatment retained 50% NOx and 73% total nitrogen, while the corresponding free draining treatment exported 17% more NOx, while retaining 50% total nitrogen.

    Symptoms due to thoracic outlet syndrome may present only in abduction, a position that cannot be investigated in conventional MR scanners. Therefore, this study was initiated to test MRI in an open magnet as a method for diagnosis of thoracic outlet syndrome. Ten volunteers and 7 patients with a clinical suspicion of thoracic outlet syndrome were investigated at 0.5 T in an open MR scanner. Sagittal 3D SPGR acquisitions were made in 0 and 90 abduction. In the patients, a similar data set was also obtained in maximal abduction. To assess compression, the minimum distance between the first rib and the clavicle, measured in a sagittal plane, was determined. In the neutral position, no significant difference was found between patients and controls. In 90 abduction, the patients had significantly smaller distance between rib and clavicle than the controls (14 vs 29 mm; p<0.01). On coronal reformatted images, the compression of the brachial plexus could often be visualised in abduction. Functional MR examination seems to be a useful diagnostic tool in thoracic outlet syndrome. Examination in abduction, which is feasible in an open scanner, is essential for the diagnosis. (orig.)

  11. Mir-29 repression in bladder outlet obstruction contributes to matrix remodeling and altered stiffness.

    Directory of Open Access Journals (Sweden)

    Mari Ekman

    Full Text Available Recent work has uncovered a role of the microRNA (miRNA miR-29 in remodeling of the extracellular matrix. Partial bladder outlet obstruction is a prevalent condition in older men with prostate enlargement that leads to matrix synthesis in the lower urinary tract and increases bladder stiffness. Here we tested the hypothesis that miR-29 is repressed in the bladder in outlet obstruction and that this has an impact on protein synthesis and matrix remodeling leading to increased bladder stiffness. c-Myc, NF-κB and SMAD3, all of which repress miR-29, were activated in the rat detrusor following partial bladder outlet obstruction but at different times. c-Myc and NF-κB activation occurred early after obstruction, and SMAD3 phosphorylation increased later, with a significant elevation at 6 weeks. c-Myc, NF-κB and SMAD3 activation, respectively, correlated with repression of miR-29b and miR-29c at 10 days of obstruction and with repression of miR-29c at 6 weeks. An mRNA microarray analysis showed that the reduction of miR-29 following outlet obstruction was associated with increased levels of miR-29 target mRNAs, including mRNAs for tropoelastin, the matricellular protein Sparc and collagen IV. Outlet obstruction increased protein levels of eight out of eight examined miR-29 targets, including tropoelastin and Sparc. Transfection of human bladder smooth muscle cells with antimiR-29c and miR-29c mimic caused reciprocal changes in target protein levels in vitro. Tamoxifen inducible and smooth muscle-specific deletion of Dicer in mice reduced miR-29 expression and increased tropoelastin and the thickness of the basal lamina surrounding smooth muscle cells in the bladder. It also increased detrusor stiffness independent of outlet obstruction. Taken together, our study supports a model where the combined repressive influences of c-Myc, NF-κB and SMAD3 reduce miR-29 in bladder outlet obstruction, and where the resulting drop in miR-29 contributes to

    Alcohol is widely consumed; however, excessive use creates serious physical, psychological and social problems and contributes to the pathogenesis of many diseases. Alcohol use disorders (that is, alcohol dependence and alcohol abuse) are maladaptive patterns of excessive drinking that lead to serious problems. Abundant evidence indicates that alcohol dependence (alcoholism) is a complex genetic disease, with variations in a large number of genes affecting a person's risk of alcoholism. Some of these genes have been identified, including two genes involved in the metabolism of alcohol (ADH1B and ALDH2) that have the strongest known affects on the risk of alcoholism. Studies continue to reveal other genes in which variants affect the risk of alcoholism or related traits, including GABRA2, CHRM2, KCNJ6 and AUTS2. As more variants are analysed and studies are combined for meta-analysis to achieve increased sample sizes, an improved picture of the many genes and pathways that affect the risk of alcoholism will be possible.

    Rapid excessive alcohol drinking frequently causes disturbance of consciousness due to head trauma, brain edema, hypoglycemia, hyponatremia, hepatic coma and so on, provoked by acute alcohol intoxication. Rapid differential diagnosis and management are extremely important to save a life. On the other hands, the chronic users of alcohol so called alcoholism has many kinds of physical diseases such as liver diseases (i.e., fatty liver, alcoholic hepatitis, alcoholic liver cirrhosis and miscellaneous liver disease), diabetes mellitus, injury to happen in drunkenness, pancreas disease (i.e., acute and chronic pancreatitis and deterioration of chronic pancreatitis), gastrontestinal diseases (i.e., gastroduodenal ulcer), and so on. Enough attention should be paid to above mentioned diseases, otherwise they would turn worse more with continuation and increase in quantity of the alcohol. It should be born in its mind that the excessive drinking becomes the weapon threatening life.

  16. Alcohol disrupts sleep homeostasis.

    Thakkar, Mahesh M; Sharma, Rishi; Sahota, Pradeep

    2015-06-01

    Alcohol is a potent somnogen and one of the most commonly used "over the counter" sleep aids. In healthy non-alcoholics, acute alcohol decreases sleep latency, consolidates and increases the quality (delta power) and quantity of NREM sleep during the first half of the night. However, sleep is disrupted during the second half. Alcoholics, both during drinking periods and during abstinences, suffer from a multitude of sleep disruptions manifested by profound insomnia, excessive daytime sleepiness, and altered sleep architecture. Furthermore, subjective and objective indicators of sleep disturbances are predictors of relapse. Finally, within the USA, it is estimated that societal costs of alcohol-related sleep disorders exceeds $18 billion. Thus, although alcohol-associated sleep problems have significant economic and clinical consequences, very little is known about how and where alcohol acts to affect sleep. In this review, we have described our attempts to unravel the mechanism of alcohol-induced sleep disruptions. We have conducted a series of experiments using two different species, rats and mice, as animal models. We performed microdialysis, immunohistochemical, pharmacological, sleep deprivation and lesion studies which suggest that the sleep-promoting effects of alcohol may be mediated via alcohol's action on the mediators of sleep homeostasis: adenosine (AD) and the wake-promoting cholinergic neurons of the basal forebrain (BF). Alcohol, via its action on AD uptake, increases extracellular AD resulting in the inhibition of BF wake-promoting neurons. Since binge alcohol consumption is a highly prevalent pattern of alcohol consumption and disrupts sleep, we examined the effects of binge drinking on sleep-wakefulness. Our results suggest that disrupted sleep homeostasis may be the primary cause of sleep disruption observed following binge drinking. Finally, we have also shown that sleep disruptions observed during acute withdrawal, are caused due to impaired

    Full Text Available Alcohol consumption and alcohol-attributable burden of disease in Africa are expected to rise in the near future, yet. increasing alcohol-related harm receives little attention from policymakers and from the population in general. Even where new legislation is proposed it is rarely enacted into law. Being at the center of social and cultural activities in many countries, alcohol’s negative role in society and contribution to countries’ burden of disease are rarely questioned. After the momentum created by the adoption in 2010 of the WHO Global Strategy and the WHO Regional Strategy (for Africa to Reduce the Harmful Use of Alcohol, and the WHO Global Action Plan for the Prevention and Control of Non-Communicable Diseases, in 2013, little seems to have been done to address the increasing use of alcohol, its associated burden and the new challenges that derive from the growing influence of the alcohol industry in Africa. In this review, we argue that to have a positive impact on the health of African populations, action addressing specific features of alcohol policy in the continent is needed, namely focusing on particularities linked to alcohol availability, like unrecorded and illicit production, outlet licensing, the expansion of formal production, marketing initiatives and taxation policies.

    Full Text Available Alcohol exerts teratogenic effects in all the gestation times, with peculiar features in relationship to the trimester of pregnancy in which alcohol is assumed. Alcohol itself and its metabolites modify DNA synthesis, cellular division, cellular migration and the fetal development. The characteristic facies of feto-alcoholic syndrome (FAS-affected baby depends on the alcohol impact on skull facial development during the first trimester of pregnancy. In association there are cerebral damages with a strong defect of brain development up to the life incompatibility. Serious consequences on fetal health also depends on dangerous effects of alcohol exposure in the organogenesis of the heart, the bone, the kidney, sensorial organs, et al. It has been demonstrated that maternal binge drinking is a high factor risk of mental retardation and of delinquent behaviour. Unfortunately, a lower alcohol intake also exerts deleterious effects on fetal health. In several countries of the world there is a high alcohol use, and this habit is increased in the women. Therefore, correct information has to be given to avoid alcohol use by women in the preconceptional time and during the pregnancy. Preliminary results of a study performed by the authors show that over 80% of pregnant and puerperal women are not unaware that more than 2 glasses of alcohol/week ingested during pregnancy can create neurological abnormalities in the fetus. However, after the information provided on alcoholic fetopathy, all women are conscious of the damage caused by the use of alcohol to the fetus during pregnancy.

    The Nuss procedure is a minimally invasive surgical repair technique for pectus excavatum with fewer delayed complications compared to open procedures. We report the case of a 22-year-old man with deep pectus excavatum who developed vascular thoracic outlet syndrome after the Nuss procedure. Further evaluation demonstrated that the first rib was causing severe obstruction of the right subclavian artery. The patient showed clinical features of subclavian artery compression. A first rib resection, division of the anterior scalene muscle and fibrous bands provided complete relief of the complaints. The forced structural and spatial changes produced by the elevation of the depressed upper chest might have caused this complication. Vascular thoracic outlet syndrome should be kept in mind as a possible complication in patients who have undergone minimally invasive repair of pectus excavatum, and this complication can be treated by first rib resection.

    Full Text Available This article commences with a summary of the ways in which various types of retail outlets have been identified at Pompeii. The conventional approach has been to identify them, and to determine their supposed activities, by the Latin terms that were casually attached to them on their discovery in the 18th and 19th centuries, even though these labels have no corroboration in the archaeological record. Subsequent scholars have commonly treated this interpretative compilation as 'primary data'. I propose a different approach to the identification of Pompeii's different types of retail food and drink outlets, one that draws on the available primary archaeological data, as well as to the use of excavation records to create 'legacy data'.

    A 65-year-old woman experienced progressive intrinsic muscle wasting on the right hand over a period of 7 years. The distribution of muscular atrophy and weakness was consistent with the area innervated by the right C8 and Th1 nerve roots. Neurophysiological examination suggested a right lower trunk lesion. An elongated right transverse process of the C7 vertebra and an aberrant subclavian artery were detected on computed tomography images, and the right lower trunk of the brachial plexus appeared to be lifted upward on magnetic resonance images. The patient was diagnosed with true neurogenic thoracic outlet syndrome. A fibrous band extending from the elongated transverse process was found during surgery, and symptoms did not progress further after resection of the band. True neurogenic thoracic outlet syndrome can cause monomelic amyotrophy, and localized neuroimaging and detailed neurophysiological examination were useful for diagnosis.

    A design study of sodium cooled metal fuel core was performed. The new core concept studied here has low radial power peaking by applying three regions core configuration with different diameters of fuel pins and the same enrichment of plutonium. The core reveals constant radial power distribution during nominal power operation, which gives the advantage of low cladding maximum temperature or high core outlet temperature with a cladding limit temperature. The core thermal hydraulic design shows that a core outlet temperature as high as that of the oxide fuel core is feasible even in the application of metal fuel pins, which have a lower cladding limit temperature than oxide fuel pins. The core concept is possible to have additional attractiveness such as high breeding ratio, high burnup, and long-term operation cycle due to its high internal conversion ratio. (author)

    Full Text Available The determination of the optimal process conditions for the operation of air coolers demands a detailed analysis of their thermohydraulic behaviour on the one hand, and the estimation of the operating costs, on the other. One of the main parameters of the thermohydraulic behaviour of this type of equipment, is the outlet air temperature. The influence of the outlet air temperature on the performance of air coolers (heat transfer coefficient overall heat transfer coefficient, required surface area for heat transfer air-side pressure drop, fan power consumption and sound pressure level was investigated in this study. All the computations, using AirCooler software [1], were applied to cooling of the process fluid and the condensation of a multicomponent vapour mixture on two industrial devices of known geometries.

    2012-01-01

    Full Text Available Fluid catalytic cracking (FCC riser reactors have complex hydrodynamics, which depend not only on operating conditions, feedstock quality, and catalyst particles characteristics, but also on the geometric configurations of the reactor. This paper presents a numerical study of the influence of different riser outlet designs on the dynamic of the flow and reactor efficiency. A three-dimensional, three-phase flow model and a four-lump kinetic scheme were used to predict the performance of the reactor. The phenomenon of vaporization of the liquid oil droplets was also analyzed. Results showed that small changes in the outlet configuration had a significant effect on the flow patterns and consequently, on the reaction yields.

    Full Text Available Mainland China has become one of the most important markets for international fast-food chains over the past decade. To study the regional spread of KFC and McDonald’s outlets in Chinese cities, the correlation of their distributions and degree of market expansion were explored and compared to analyze both the local and the global spatial autocorrelations. A geographically weighted Poisson regression model was also used to examine the influence of demographic, economic, and geographic factors on their spatial distributions. The findings of this comparative study reveal the site selection criteria at the city level by studying the differences and similarities in outlet distributions for KFC and McDonald’s. The presented results can guide other chains to enhance business location planning and formulate regional development policy.

    Background. We investigated differences in family social class associations between food outlet exposure and fruit and vegetable intake. Methods. We supplemented data from the 2006 Health Behavior in School Aged Children Study (n = 6, 096) with geocoded food outlet information surrounding schools (n = 80). We used multilevel logistic regression to examine associations between infrequent fruit and vegetable intake and supermarket and fast food outlet concentration, stratified by family social class. Results. Boys and older children were most likely to eat fruit and vegetables infrequently. High fast food outlet exposure was marginally significant for low fruit intake in low social class children only. Children from middle and low social class backgrounds attending schools with combined high fast food outlet/low supermarket exposure were most likely to report infrequent fruit intake (ORlow = 1.60; CI:  1.02–2.45; ORmid = 1.40; CI:  1.03–190). Children from low social class backgrounds were also likely to report infrequent vegetable intake, given low supermarket and high fast food outlet exposure (OR = 1.79; CI:  0.99–3.21). Conclusion. Our findings suggest social class modifies the relationship between intake and food outlet concentration. School interventions improving fruit and vegetable intake should consider neighborhood surroundings, targetting older children from low social class backgrounds. PMID:22988491

    A common belief is that alkali ingestion causes severe esophageal damage and limited gastric injury due to the buffering action of acid. Gastric injury has been observed in patients who ingested alkali. Gastric outlet obstruction (GOO) secondary to caustic ingestion occurs due to fibrosis after resolution of the acute injury and inflammation, most commonly 6 to 12 weeks after initial ingestion.

    Despite recent development of computational fluid dynamics (CFD) research, analysis of computational fluid dynamics of cerebral vessels has several limitations. Although blood is a non-Newtonian fluid, velocity and pressure fields were computed under the assumptions of incompressible, laminar, steady-state flows and Newtonian fluid dynamics. The pulsatile nature of blood flow is not properly applied in inlet and outlet boundaries. Therefore, we present these technical limitations and discuss the possible solution by comparing the theoretical and computational studies.

  18. Alcohol and atherosclerosis

    Directory of Open Access Journals (Sweden)

    Murilo Foppa

    2001-02-01

    Full Text Available Observational studies have attributed a protective effect to alcohol consumption on the development of atherosclerosis and cardiovascular morbidity and mortality. Alcohol intake in the amount of one to two drinks per day results in an estimated 20-40% reduction in cardiovascular events. An additional protective effect, according to major cohort studies, has been attributed to wine, probably due to antioxidant effects and platelet antiaggregation agents. On the other hand, the influence of different patterns of alcohol consumption and environmental factors may explain a great part of the additional effect of wine. Protection may be mediated by modulation of other risk factors, because alcohol increases HDL-C, produces a biphasic response on blood pressure, and modulates the endothelial function, while it neither increases body weight nor impairs glucose-insulin homeostasis. Alcohol may also have a direct effect on atherogenesis. Despite these favorable effects, the current evidence is not enough to justify prescribing alcohol to prevent cardiovascular disease.

    Alcoholism and alcohol-associated organ injury is one of the major health problems worldwide. Alcohol may lead to an alteration in intermediary metabolism and the relation between alcohol intake and body weight is a paradox. The effect of alcohol intake on resting metabolic rate, assessed by indirect calorimetry, and lipid oxidation, is still controversial. Small quantities of ethanol seem to have no effect on body weight. Ingestion of moderate amounts may lead to an increase in body weight, via a lipid-oxidizing suppressive effect. Chronic intake of excessive amounts in alcoholics leads to a decrease in body weight, probably via increased lipid oxidation and energy expenditure. Chronic ethanol abuse alters lipid-soluble (vitamins A, D and E) and water-soluble (B-complex vitamins, vitamin C) vitamins status, and some trace elements status such as magnesium, selenium or zinc.

  20. Air demand estimation in bottom outlets with the particle finite element method - Susqueda Dam case study

    2016-06-01

    Dam bottom outlets play a vital role in dam operation and safety, as they allow controlling the water surface elevation below the spillway level. For partial openings, water flows under the gate lip at high velocity and drags the air downstream of the gate, which may cause damages due to cavitation and vibration. The convenience of installing air vents in dam bottom outlets is well known by practitioners. The design of this element depends basically on the maximum air flow through the air vent, which in turn is a function of the specific geometry and the boundary conditions. The intrinsic features of this phenomenon makes it hard to analyse either on site or in full scaled experimental facilities. As a consequence, empirical formulas are frequently employed, which offer a conservative estimate of the maximum air flow. In this work, the particle finite element method was used to model the air-water interaction in Susqueda Dam bottom outlet, with different gate openings. Specific enhancements of the formulation were developed to consider air-water interaction. The results were analysed as compared to the conventional design criteria and to information gathered on site during the gate operation tests. This analysis suggests that numerical modelling with the PFEM can be helpful for the design of this kind of hydraulic works.

    2003-04-01

    This article evaluates treatment outcomes of urethrolysis with the Martius labial fat pad graft for patients with outlet obstruction after incontinence surgery. A total of 23 women were diagnosed with iatrogenic bladder outlet obstruction by urinary retention, urodynamic criteria, physical examination findings, and/or temporal relation of voiding dysfunction to anti-incontinence surgery. The urodynamic definition of female outlet obstruction was a maximum flow rate 20 cm of water. Surgical treatment consisted of urethrolysis with complete circumferential urethral mobilization. A Martius labial fat pad graft was used to circumferentially wrap the urethra. No concurrent resuspension procedures were performed. Procedure efficacy was determined by retrospective review and phone interview. Mean patient age was 55 years (range, 37 to 85 years). Mean postoperative follow-up time was 15 months (maximum, 44 months). All patients related voiding dysfunction symptoms to their anti-incontinence surgery. In all, 17 of 23 (74%) patients had preoperative urinary retention requiring catheterization, and 63% of patients met urodynamic criteria for obstruction. After urethrolysis with a Martius labial fat pad graft, 20 of 23 (87%) patients had complete resolution of their obstruction; 3 patients required persistent catheterization. Postoperative stress incontinence was reported by 6 of 23 (13%) patients. Urodynamically documented detrusor instability occurred in 6 of 23 (26%) patients with de novo detrusor instability occurring in 3 of 15 (20%) patients.

  2. Use of Mobile Pipeline with Self-regulated Water Outlets for Furrow Irrigation

    Full Text Available Surface irrigation is one of the most common irrigation methods, but it has its own significant drawbacks. A mobile pipeline for furrow irrigation from closed irrigation network was designed and its parameters were proved in order to improve furrow irrigation. The mobile pipeline consists of plastic pipes based on 10 pairs of spring skis connected in the middle by a flexible connection. It is known that water flow into the furrow decreases along the pipeline due to pressure losses along the length of the pipeline. It was proposed to use water outlets ensuring uniform supply of water to each furrow by the presence of the butterfly valve in housing of the water outlet in the mobile pipeline. In order to ensure sustainable valve position, an equation was derived and values of the area of the upper and bottom parts of the valve were obtained. According to the pipeline field test results, water distribution uniformity coefficient through the outlets was 0.98, at a flow rate of 1.0-3.0 l∙s-1 and hydraulic slopes along the pipeline of 0.001−0.005.

  3. Hydraulic response and nitrogen retention in bioretention mesocosms with regulated outlets: part I--hydraulic response.

    2011-08-01

    In bioretention systems used for stormwater treatment, runoff interception improves with increased infiltration rates. However, nitrogen retention improves with increased retention time or decreasing infiltration rates. These contrasting responses were analyzed in 240-L experimental mesocosms using a variety of media treatments. The mesocosms were vegetated, except for one barren control. Dual-stage outlets were installed to extend retention time and equalize hydraulic responses. One unregulated treatment was free-draining. This part 1 paper presents the media properties and hydraulic responses. The highly aggregated media had saturated hydraulic conductivities ranging from 20.7 to 59.6 cm/h in August 2008 (austral winter), which increased to 42.8 to 110.6 cm/h in March 2009 (austral summer). The outlet regulated mesocosms provided retention over 8 times longer than the free-draining mesocosms, while still being able to capture large events. The outlets provide adaptive management for bioretention design to improve both runoff capture and nitrogen retention.

    Full Text Available Using thermal pressure ventilation principles to achieve passive ventilation in buildings is an important way to promote green and low consumption building strategy. The reasonable vents layout design can fully tap the potential of thermal pressure ventilation. Aimed to civil buildings with internal heating source, using Computational Fluid Dynamics (CFD technology, the effects of outlets layout on thermal natural ventilation in rooms were studied. Three types of typical air outlets distribution patterns were considered and the airflow distribution of thermal natural ventilation in rooms was simulated. The ventilation rates and the average workspace temperatures of different simulated conditions were given. The velocity and temperature fields of different simulated conditions were analyzed and the indoor thermal stratification characteristics were discussed. In addition, the effective heat coefficients of different simulated conditions were analyzed and compared. The results show that the strategy of dispersed outlets on ceiling can achieve the optimal natural ventilation effect. The results can provide theoretical references for the design of natural ventilation system in civil buildings.

  5. Review of recent developments and applications in low-pressure (vacuum outlet) gas chromatography.

    The concept of low pressure (LP) vacuum outlet gas chromatography (GC) was introduced more than 50 years ago, but it was not until the 2000s that its theoretical applicability to fast analysis of GC-amenable chemicals was realized. In practice, LPGC is implemented by placing the outlet of a short, wide (typically 10-15 m, 0.53 mm inner diameter) analytical column under vacuum conditions, which speeds the separation by reducing viscosity of the carrier gas, thereby leading to a higher optimal flow rate for the most separation efficiency. To keep the inlet at normal operating pressures, the analytical column is commonly coupled to a short, narrow uncoated restriction capillary that also acts as a guard column. The faster separations in LPGC usually result in worse separation efficiency relative to conventional GC, but selective detection usually overcomes this drawback. Mass spectrometry (MS) provides highly selective and sensitive universal detection, and nearly all GC-MS instruments provide vacuum outlet conditions for implementation of LPGC-MS(/MS) without need for adaptations. In addition to higher sample throughput, LPGC provides other benefits, including lower detection limits, less chance of analyte degradation, reduced peak tailing, increased sample loadability, and more ruggedness without overly narrow peaks that would necessitate excessively fast data acquisition rates. This critical review summarizes recent developments in the application of LPGC with MS and other detectors in the analysis of pesticides, environmental contaminants, explosives, phytosterols, and other semi-volatile compounds.

  6. Alcohol-Induced Blackout

    Dai Jin Kim

    2009-11-01

    Full Text Available For a long time, alcohol was thought to exert a general depressant effect on the central nervous system (CNS. However, currently the consensus is that specific regions of the brain are selectively vulnerable to the acute effects of alcohol. An alcohol-induced blackout is the classic example; the subject is temporarily unable to form new long-term memories while relatively maintaining other skills such as talking or even driving. A recent study showed that alcohol can cause retrograde memory impairment, that is, blackouts due to retrieval impairments as well as those due to deficits in encoding. Alcoholic blackouts may be complete (en bloc or partial (fragmentary depending on severity of memory impairment. In fragmentary blackouts, cueing often aids recall. Memory impairment during acute intoxication involves dysfunction of episodic memory, a type of memory encoded with spatial and social context. Recent studies have shown that there are multiple memory systems supported by discrete brain regions, and the acute effects of alcohol on learning and memory may result from alteration of the hippocampus and related structures on a cellular level. A rapid increase in blood alcohol concentration (BAC is most consistently associated with the likelihood of a blackout. However, not all subjects experience blackouts, implying that genetic factors play a role in determining CNS vulnerability to the effects of alcohol. This factor may predispose an individual to alcoholism, as altered memory function during intoxication may affect an individual‟s alcohol expectancy; one may perceive positive aspects of intoxication while unintentionally ignoring the negative aspects. Extensive research on memory and learning as well as findings related to the acute effects of alcohol on the brain may elucidate the mechanisms and impact associated with the alcohol- induced blackout.

    Alcohol abuse has numerous adverse health and social consequences. The consumer response to changes in alcohol affordability is an important issue on alcohol policy debates. Studies from many countries have shown an inverse relationship between alcohol prices and alcohol consumption in the population. There are, however, suggestions that increasing the price of alcohol by rising taxes may have limited effect on alcohol-related problems, associated with long-term heavy drinking. The aim of the present study was to evaluate the relationship between alcohol affordability and alcohol-related mortality rates in post-Soviet Belarus. For this purpose trends in alcohol-related mortality rates (mortality from liver cirrhosis, pancreatitis, alcoholism and alcohol psychoses) and affordability of vodka between 1990 and 2010 were compared. The time series analysis revealed that 1% increase in vodka affordability is associated with an increase in liver cirrhosis mortality of 0,77%, an increase in pancreatitis mortality of 0.53%, an increase in mortality from alcoholism and alcohol psychoses of 0,70%. The major conclusion emerging from this study is that affordability of alcohol is one of the most important predictor of alcohol-related problems in a population. These findings provide additional evidence that decreasing in affordability of alcohol is an effective strategy for reducing alcohol consumption and alcohol-related harm.

    During the last 15 years several mass movements of various size and origin, e.g. rock avalanches, rock slides and debris slides have been observed to have fall on outlet glaciers in Iceland. This should not come as a surprise in this type of glacial environment, but in a way it does. When looking at the history only few mass movements are recorded to have fall on outlet glaciers in Iceland, during the decades before the year 2000 or since 1960. This "lack of mass movements" can be explained by the fact that fewer observations and monitoring were done in the past, but is it so or are we seeing increasing activity? Looking at the distribution of the known mass movements, two activity periods cam be identified. The former one around 1970 and the second one starting around 2000 and is still ongoing. Both of these periods are characterized by warmer climate leading to retreating phases of glaciers. Two larger mass movements are known from these two retreating periods. The former one occurred in January 1967. Then a large rockslide fell on the snout and into the glacial lake of the Steinholtsjökull outlet glacier in the northern side of the Eyjafjallajökull ice cap. The rockslide broke up the snout of the glacier and caused large floodwave bursting down the Steinholtsdalur valley transporting large volume of sediments down its path. The later one occurred in 2007, when a large rockavalanche fell on the Morsárjökull outlet glacier, in the southern side of the Vatnajökull ice cap. The avalanche debris covered around 1/5 of the glacier surface. Today the retreat and thinning of glaciers in Iceland are extremely rapid. The consequences of such a rapid retreat are e.g. unstable valley slopes surrounding the outlet glaciers, both in loose sediments and bedrock, thawing of mountain permafrost and not least formation of glacial lakes in front of the rapid retreating ice margins. Such conditions can become extremely hazardous, as seen by the above mentioned examples, both

    Reservoirs are used to store water for multiple purposes and are therefore of great importance for our society. Regularly inspections of the dam structure and the bottom outlets are necessary to ensure a safe operation of these structures. The release of water from the reservoirs for this procedure often results in high suspended sediment concentrations downstream by the remobilization of deposited sediments, which may result further in negative effects on the downstream located habitats. Due to a careful elaborated monitoring concept, e.g. regarding the opening procedure of the bottom outlets, it is possible to change the management strategy and to avoid or to minimize ecological impacts. Within this study a monitoring concept is developed and implemented to observe occurring suspended sediment concentrations during the opening of the bottom outlets of a small reservoir in the alpine region. The measurement concept includes suspended sediment concentration and discharge measurements at the two upstream located tributaries as well as suspended sediment concentration measurements downstream. Two stations are selected downstream with a distance of 750 m and 2,000 m from the dam. To ensure a complete series of concentrations over time bottom samples, Imhoff-cones as well as turbidity meters are implemented. Whereas the turbidity meters ensure a permanent observation of the conditions (will be calibrated with laboratory results from the bottle samples), the Imhoff-cones make it possible to intervene right away into the process of releasing water. A second focus lies on the downstream located river bed, which is monitored before and after the opening of the bottom outlets in order to assess morphodynamical changes such as river bed clogging occurs. Therefore sediment samples with the so called freeze-panel technique are collected before and after the opening of the bottom outlets to quantify possible changes of the bed material. The results show that downstream habitats

    Full Text Available Problem statement: To date, the therapeutic strategy efficacy against memory impairment induced by alcohol intoxication is still limited. The novel therapeutic strategy which is easy to approach, less toxic and less cost is required. Based on the role of oxidative stress in memory impairment induced by alcohol, the neuroprotective effect of substance possessing antioxidant has gained much attention. Therefore, we aimed to determine the effect of Morus alba fruits, substance possessing antioxidant, on spatial memory and brain damage in hippocampus. Approach: Male Wistar rats were induced alcoholism by increasing the alcohol concentration in drinking water gradually increased to 30% within 15-week period. Then, the alcoholic rats were orally given mulberry fruits powder at doses of 2, 10 and 50 mg kg-1 BW at a period of 14 days. The memory was assessed using Morris water maze after single administration and every 7 days until the end of the experimental period and at the end of experiment, hippocampus was isolated and determined the neuron density. In addition, the evaluation of Acetylcholinesterase (AChE activity and Malondialdehyde (MDA level were also performed. Results: Our results showed that all doses of mulberry fruits enhanced spatial memory and neurons density in hippocampus. The suppression of both AChE activity and MDA level were also observed. These results suggested that the neuroprotection of mulberry fruits might occur partly via the decreased oxidative stress damage while the cognitive enhancing effect might occur partly via the increased hippocampal neuron density and the suppression of AChE activity. Conclusion: Mulberry fruits can protect against brain damage and memory impairment induced by alcoholism. Therefore, mulberry fruits may be served as natural resource for developing food supplement against alcoholism. However, further researches about possible active ingredient and pharmacokinetic are required before moving forward

    The manner of innervation of the pelvic outlet muscles in fowl (Gallus gallus domesticus) was examined in detail in four male pelvic halves. The segmental arrangement of the nerve supply in the sacral and pudendal plexuses was compared to that of Lacertilia and Urodela as a basis for a morphological analysis of the pelvic outlet muscles. From the viewpoint of innervation, the pelvic outlet muscles of fowl are classified into two groups: a sphincter muscle group and a levator muscle group. These two groups are closely related to the ventral muscles of the pelvic limb. In contrast to the morphology of pelvic outlet muscles in lacertilians, in fowl the caudal muscle element does not contribute to the formation of these muscles.

    This study aims to analyze seismic damage of reinforced outlet piers of arch dams by the nonlinear finite element (FE) sub-model method. First, the dam-foundation system is modeled and analyzed, in which the effects of infinite foundation, contraction joints, and nonlinear concrete are taken into account. The detailed structures of the outlet pier are then simulated with a refined FE model in the sub-model analysis. In this way the damage mechanism of the plain (unreinforced) outlet pier is analyzed, and the effects of two reinforcement measures (i.e., post-tensioned anchor cables and reinforcing bar) on the dynamic damage to the outlet pier are investigated comprehensively. Results show that the plain pier is damaged severely by strong earthquakes while implementation of post-tensioned anchor cables strengthens the pier effectively. In addition, radiation damping strongly alleviates seismic damage to the piers.

    Acute alcohol intoxication causes cellular changes in the brain that last for hours, while chronic alcohol use induces widespread neuroadaptations in the nervous system that can last a lifetime. Chronic alcohol use and the progression into dependence involve the remodeling of synapses caused by changes in gene expression produced by alcohol. The progression of alcohol use, abuse, and dependence can be divided into stages, which include intoxication, withdrawal, and craving. Each stage is associated with specific changes in gene expression, cellular function, brain circuits, and ultimately behavior. What are the molecular mechanisms underlying the transition from recreational use (acute) to dependence (chronic)? What cellular adaptations result in drug memory retention, leading to the persistence of addictive behaviors, even after prolonged drug abstinence? Research into the neurobiology of alcoholism aims to answer these questions. This chapter will describe the molecular adaptations caused by alcohol use and dependence, and will outline key neurochemical participants in alcoholism at the molecular level, which are also potential targets for therapy.

    Chronic use of alcohol is considered to be a potential risk factor for the incidence of type 2 diabetes mellitus (T2DM), which causes insulin resistance and pancreatic β-cell dysfunction that is a prerequisite for the development of diabetes. However, alcohol consumption in diabetes has been controversial and more detailed information on the diabetogenic impact of alcohol seems warranted. Diabetes, especially T2DM, causes dysregulation of various metabolic processes, which includes a defect in the insulin-mediated glucose function of adipocytes, and an impaired insulin action in the liver. In addition, neurobiological profiles of alcoholism are linked to the effects of a disruption of glucose homeostasis and of insulin resistance, which are affected by altered appetite that regulates the peptides and neurotrophic factors. Since conditions, which precede the onset of diabetes that are associated with alcoholism is one of the crucial public problems, researches in efforts to prevent and treat diabetes with alcohol dependence, receives special clinical interest. Therefore, the purpose of this mini-review is to provide the recent progress and current theories in the interplay between alcoholism and diabetes. Further, the purpose of this study also includes summarizing the pathophysiological mechanisms in the neurobiology of alcoholism.

    Full Text Available Atherosclerosis is manifested as coronary artery disease (CAD, ischemic stroke and peripheral vascular disease. Moderate alcohol consumption has been associated with reduction of CAD complications. Apparently, red wine offers more benefits than any other kind of drinks, probably due to flavonoids. Alcohol alters lipoproteins and the coagulation system. The flavonoids induce vascular relaxation by mechanisms that are both dependent and independent of nitric oxide, inhibits many of the cellular reactions associated with atherosclerosis and inflammation, such as endothelial expression of vascular adhesion molecules and release of cytokines from polymorphonuclear leukocytes. Hypertension is also influenced by the alcohol intake. Thus, heavy alcohol intake is almost always associated with systemic hypertension, and hence shall be avoided. In individuals that ingest excess alcohol, there is higher risk of coronary occlusion, arrhythmias, hepatic cirrhosis, upper gastrointestinal cancers, fetal alcohol syndrome, murders, sex crimes, traffic and industrial accidents, robberies, and psychosis. Alcohol is no treatment for atherosclerosis; but it doesn't need to be prohibited for everyone. Thus moderate amounts of alcohol (1-2 drinks/day, especially red wine, may be allowed for those at risk for atherosclerosis complications.

    Chronic alcohol consumption can induce alterations in the function and morphology of most if not all brain systems and structures. However, the exact mechanism of brain damage in alcoholics remains unknown. Partial recovery of brain function with abstinence suggests that a proportion of the deficits must be functional in origin (i.e. plastic changes of nerve cells) while neuronal loss from selected brain regions indicates permanent and irreversible damage. There is growing evidence that chronic alcoholism is associated with a derangement in the sulfur amino acid metabolism. Recently, it has been shown that excitatory amino acid (EAA) neurotransmitters and homocysteine levels are elevated in patients who underwent withdrawal from alcohol. Furthermore, it has been found that homocysteine induces neuronal cell damage by stimulating NMDA receptors as well as by producing free radicals. Homocysteine neurotoxicity via overstimulation of N-methyl-D-aspartate receptors may contribute to the pathogenesis of both brain shrinkage and withdrawal seizures linked to alcoholism.

    Diminished sexual functioning among individuals dependent upon alcohol has been assessed. Ninety-seven male patients entered the study, all inpatients as the unit for treatment of alcoholism and drug addiction (Villa 6) in Porirua Hospital, Porirua. The sexual ability of these patients before the development of alcoholism was also rated for the same items and this rating was used as a control. Of the 97 patients, 69 (71 percent) suffered from sexual dysfunction for a period more than 12 months prior to admission to hospital. The disturbances noted were diminished sexual desire (58 percent of patients), erectile impotence (16 percent), premature ejaculation (4 percent), ejaculatory in competence (22 percent). A high proportion of the alcoholics showed signs of sexual deviation-19 percent having performed sexual crimes and a further 28 percent having repeated thought of sexual crimes. The possible causes of alcohol induced sexual dysfunction are discussed.

  19. Hydrophobic and hydrophilic interactions in aqueous mixtures of alcohols at a hydrophobic surface.

    2013-09-21

    Aqueous solutions of alcohols are interesting because of their anomalous behavior that is believed to be due to the molecular structuring of water and alcohol around each other in solution. The interfacial structuring and properties are significant for application in alcohol purification processes and biomolecular structure. Here we study aqueous mixtures of short alcohols (methanol, ethanol, 1-propanol, and 2-propanol) at a hydrophobic surface using interfacial statistical associating fluid theory which is a perturbation density functional theory. The addition of a small amount of alcohol decreases the interfacial tension of water drastically. This trend in interfacial tension can be explained by the structure of water and alcohol next to the surface. The hydrophobic group of an added alcohol preferentially goes to the surface preserving the structure of water in the bulk. For a given bulk alcohol concentration, water mixed with the different alcohols has different interfacial tensions with propanol having a lower interfacial tension than methanol and ethanol. 2-propanol is not as effective in decreasing the interfacial tension as 1-propanol because it partitions poorly to the surface due to its larger excluded volume. But for a given surface alcohol mole fraction, all the alcohol mixtures give similar values for interfacial tension. For separation of alcohol from water, methods that take advantage of the high surface mole fraction of alcohol have advantages compared to separation using the vapor in equilibrium with a water-alcohol liquid.

    Alcohol-related traumatic brain injury (TBI) is a common condition in medical and forensic practice, and results in high prehospital mortality. We investigated the mechanism of chronic alcoholism-related mortality by examining the effects of alcohol on the synapses of the medulla oblongata in a rat model of TBI. Seventy adult male Sprague-Dawley rats were randomly assigned to either ethanol (EtOH) group, EtOH-TBI group, or control groups (water group, water-TBI group). To establish chronic alcoholism model, rats in the EtOH group were given EtOH twice daily (4 g/kg for 2 weeks and 6 g/kg for another 2 weeks). The rats also received a minor strike on the occipital tuberosity with an iron pendulum. Histopathologic and ultrastructure changes and the numerical density of the synapses in the medulla oblongata were examined. Expression of postsynaptic density-95 (PSD-95) in the medulla oblongata was measured by ELISA. Compared with rats in the control group, rats in the chronic alcoholism group showed: (1) minor axonal degeneration; (2) a significant decrease in the numerical density of synapses (p alcoholism induces significant synapse loss and axonal impairment in the medulla oblongata and renders the brain more susceptible to TBI. The combined effects of chronic alcoholism and TBI induce significant synapse and axon impairment and result in high mortality.

    2014-01-01

    Determination of the volume content of ethanol in the alcohol products in practice is usually determined by pycnometry, electronic densimetry, or densimetry using a hydrostatic balance in accordance with Commission Regulation No 2870/2000. However, these methods determine directly only density of the tested liquid sample and does not take into account the effects of other volatile components such as aldehydes, esters and higher alcohols. So they are appropriate only for binary water-ethanol solutions in accordance with international table adopted by the International Legal Metrology Organization in its Recommendation No 22. Availability notable concentrations of the higher alcohols and ethers in different alcohol-based products, e. g. in whisky, cognac, brandy, wine as well as in waste alcohol and alcohol beverage production, leads to the significant contribution of these compounds in the value of the density of tested alcohol-containing sample. As a result, determination of the volume of ethanol content for ...

    The flow patterns in the inlet and outlet conduits have a decisive effect on the safe, stable, and highly efficient operation of the pump in a large pumping station with low head. The numerical simulation of three-dimensional (3D) turbulence flow in conduits is an important method to study the hydraulic performance and conduct an optimum hydraulic design for the conduits. With the analyses of the flow patterns in the inlet and outlet conduits, the boundary conditions of the numerical simulation for them can be determined. The main obtained conclusions are as follows: (i) Under normal operation conditions, there is essentially no pre-swirl flow at the impeller chamber inlet of an axial-flow pump system, based on which the boundary condition at the inlet conduit may be defined. (ii) The circulation at the guide vane outlet of an axial-flow pump system has a great effect on the hydraulic performance of the outlet conduit, and there is optimum circulation for the performance. Therefore, it is strongly suggested to design the guide vane according to the optimum circulation. (iii) The residual circulation at the guide vane outlet needs to be considered for the inlet boundary condition of the outlet conduit, and the value of the circulation may be measured in a specially designed test model.

  12. Investigating connections between local-remote atmospheric variability and Greenland outlet glacier behavior

    Science.gov (United States)

    Sobolowski, Stefan; Chen, Linling; Miles, Victoria

    2016-04-01

    The outlet glaciers along the margins of the Greenland Ice Sheet (GrIS) exhibit a range of behaviors, which are crucial for understanding GrIS mass changes from a dynamical point of view. However, the drivers of this behavior are still poorly understood. Arguments (counter-arguments) have been made for a strong (weak) local oceanic influence on marine terminating outlet glaciers while decadal-scale drivers linked to fluctuations in the Ice sheet itself and the North Atlantic ocean (e.g. Atlantic Multidecadal Variability) have also been posited as drivers. Recently there have also been studies linking (e.g. seasonal to interannual) atmospheric variability, synoptic activity and the Ice Sheet variability. But these studies typically investigate atmospheric links to the large-scale behavior of the Ice Sheet itself and do not go down to the scale of the outlet glaciers. Conversely, investigations of the outlet glaciers often do not include potential links to non-local atmospheric dynamics. Here the authors attempt to bridge the gap and investigate the relationship between atmospheric variability across a range of scales and the behavior of three outlet glaciers on Greenland's southeast coast over a 33-year period (1980-2012). The glaciers - Helheim, Midgard and Fenris - are near Tasiilaq, are marine terminating and exhibit varying degree of connection to the GrIS. ERA-Interim reanalysis, sea-ice data and glacier observations are used for the investigation. Long records of mass balance are unavailable for these glaciers and front position is employed as a measure of glacier atmosphere interactions across multiple scales, as it exhibits robust relationships to atmospheric variability on time scales of seasons to many years, with the strongest relationships seen at seasonal - interannual time scales. The authors do not make the argument that front position is a suitable proxy for mass balance, only that it is indicative of the role of local and remote atmospheric

  13. Investigating the flow and stress regime at the front of a tidewater outlet glacier

    2016-04-01

    Dynamic changes in ocean-terminating glaciers are responsible for approximately half of the current high rate of mass loss of the Greenland ice sheet. The related calving process, which occurs when the stresses at the calving front exceed the fracture toughness of ice, is still not well understood and poorly represented in current generation ice-sheet models, but is a crucial requisite to understand and model dynamics and future mass loss of the ice sheet. Here, we use a two-dimensional finite-element model to compute the stress and flow fields near the front of a tidewater outlet glacier. First, we perform a sensitivity analysis for an idealized glacier exploring the effects of variable calving front slope, water depth and basal sliding. We then apply the model to two flowlines of Eqip Sermia, an ocean terminating outlet glacier in West Greenland. Detailed velocity and geometry measurements obtained from terrestrial radar interferometry serve as constraints to the model. These flowline geometries and velocities strongly differ. One flowline ends with a ˜ 50 meter vertical cliff, close to floatation, while the other has a 150-200 meter high grounded front with a ˜ 45° slope and for which extrusion flow is observed. These different geometry settings lead to substantial difference in stress and flow regimes. This stress analysis improves our understanding of how and where the ice is susceptible to failure and crevasse formation for different idealized as well as real conditions. In further work, we aim to use this information as a constraint to investigate the short-term and long-term processes related to outlet glacier calving.

[Siemens Medical Systems, Forcheim (Germany); Guillot, J.P. [Dept. of Radiology, University Center Hospital Calmette, Lille (France)

    2001-04-01

    The aim of this study was to evaluate dose reduction in spiral CT angiography of the thoracic outlet by on-line tube-current control. Prospectively, 114 patients undergoing spiral CT angiography of the subclavian artery for thoracic outlet arterial syndromes were evaluated with and without tube-current modulation at the same session (scanning parameters for the two successive angiograms, one in the neutral position and one after the postural maneuver): 140 kV; 206 mA; scan time 0.75 s; collimation 3 mm; pitch = (1). The dose reduction system was applied in the neutral position in the first 92 consecutive patients and after postural maneuver in the remaining 22 consecutive patients. Dose reduction and image quality were analyzed in the overall study group (group 1; n = 114). The influence of the arm position was assessed in 44 of the 114 patients (group 2), matched by the transverse diameter of the upper thorax. The mean dose reduction was 33 % in group 1 (range 22-40 %) and 34 % in group 2 (range 26-40 %). In group 2 the only difference in image quality was a significantly higher frequency of graininess on low-dose scans compared with reference scans whatever the patient's arm position, graded as minimal in 38 of the 44 patients (86 %). When the low-dose technique was applied after postural maneuver in group 2: (a) the mean dose reduction was significantly higher (35 vs 32 % in the neutral position; p = 0.006); (b) graininess was less frequent (82 vs 91 % in the neutral position); and (c) the percentage of graininess graded as minimal was significantly higher (83 vs 70 % in the neutral position; p = 0.2027). On-line tube-current modulation enables dose reduction on high-quality, diagnostic spiral CT angiograms of the thoracic outlet and should be applied during data acquisition in the neutral position and after postural maneuver for optimal use.

  15. Importance of basal processes in simulations of a surging Svalbard outlet glacier

    Directory of Open Access Journals (Sweden)

    R. Gladstone

    2013-12-01

    Full Text Available The outlet glacier of Basin 3 (B3 of Austfonna icecap, Svalbard, is one of the fastest outlet glaciers in Svalbard, and shows dramatic changes since 1995. In addition to previously observed seasonal summer speed up associated with the melt season, the winter speed of B3 has accelerated approximately five fold since 1995. We use the Elmer/Ice full Stokes model for ice dynamics to infer spatial distributions of basal drag for the winter seasons of 1995, 2008 and 2011. This "inverse" method is based on minimising discrepancy between modelled and observed surface velocities, using satellite remotely sensed velocity fields. We generate steady state temperature distributions for the three time periods. Frictional heating caused by basal sliding contributes significantly to basal temperatures of the B3 outlet glacier, which exhibits a uniform steady state basal temperature at pressure melting point in all three cases. We present a sensitivity experiment consisting of transient simulations under present day forcing to demonstrate that using a temporally fixed basal drag field obtained through inversion can lead to thickness change errors of the order of 2 m per year. Hence it is essential to incorporate the evolution of basal processes in future projections of the basin. Informed by a combination of our inverse method results and previous studies, we hypothesize a system of processes and feedbacks involving till deformation and basal hydrology to explain both the seasonal accelerations and the ongoing inter-annual speed up, and speculate on the wider relevance of deformable till mechanics to non-surging glaciers.

  17. Delayed Diagnosis of Gastric Outlet Obstruction from Bouveret Syndrome in a Young Woman

    Directory of Open Access Journals (Sweden)

    Smith, Zachary

    2014-11-01

    Full Text Available Bouveret syndrome is a rare presentation of gastric outlet obstruction caused by a gallstone in the proximal duodenum via a bilioenteric fistula. This is an infrequent although clinically significant cause of abdominal pain, almost exclusively in the elderly. The clinical presentation is similar to that of a small bowel obstruction with abdominal pain, nausea and vomiting. Surgery or endoscopy is often required for definitive diagnosis and therapy. We describe the case of a young woman with this condition who had a delayed diagnosis in part because of her age and the rarity of the condition. [West J Emerg Med. 2015;16(1:151-153.

  18. Thoracic Outlet Syndrome in a Volleyball Player Due to Nonunion of the First Rib Fracture.

    Puttmann, Kathleen T; Satiani, Bhagwan; Vaccaro, Patrick

    2016-11-01

    Fracture of the first rib with ensuing callus formation is a rare cause of thoracic outlet syndrome. We report a case of a 17-year-old female volleyball player who presented with months of chronic arm pain. Radiographic imaging demonstrated nonunion fracture of the first rib. Physical therapy had been unsuccessful in relieving the pain, and surgical management was performed with resection of the first rib through a transaxillary approach with complete resolution of symptoms. Inflammation surrounding such fractures may destroy tissue planes, making dissection more technically difficult.

    2005-01-01

    A new style of discharge process from a vertical open-top pipe with capillary outlet is reported. The outflux fluctuates greatly with time and the bulk condensed granular flow in the pipe shows stop-and-go motion when the filling height is above a threshold. When the filling height falls towards the threshold, led by a transitional stage, the outflux and the bulk movement become much stable. The upper surface dropping velocity variation is measured. A heuristic theory is proposed to understand the stop-and-go motion and the transitional behavior.

    A self-regulated water separator provides centrifugal separation of fuel cell product water from oxidant gas. The system uses the flow energy of the fuel cell's two-phase water and oxidant flow stream and a regulated ejector or other reactant circulation pump providing the two-phase fluid flow. The system further uses a means of controlling the water outlet flow rate away from the water separator that uses both the ejector's or reactant pump's supply pressure and a compressibility sensor to provide overall control of separated water flow either back to the separator or away from the separator.

  3. Alcoholism: genes and mechanisms.

    Science.gov (United States)

    Oroszi, Gabor; Goldman, David

    2004-12-01

    Alcoholism is a chronic relapsing/remitting disease that is frequently unrecognized and untreated, in part because of the partial efficacy of treatment. Only approximately one-third of patients remain abstinent and one-third have fully relapsed 1 year after withdrawal from alcohol, with treated patients doing substantially better than untreated [1]. The partial effectiveness of strategies for prevention and treatment, and variation in clinical course and side effects, represent a challenge and an opportunity to better understand the neurobiology of addiction. The strong heritability of alcoholism suggests the existence of inherited functional variants of genes that alter the metabolism of alcohol and variants of other genes that alter the neurobiologies of reward, executive cognitive function, anxiety/dysphoria, and neuronal plasticity. Each of these neurobiologies has been identified as a critical domain in the addictions. Functional alleles that alter alcoholism-related intermediate phenotypes include common alcohol dehydrogenase 1B and aldehyde dehydrogenase 2 variants that cause the aversive flushing reaction; catechol-O-methyltransferase (COMT) Val158Met leading to differences in three aspects of neurobiology: executive cognitive function, stress/anxiety response, and opioid function; opioid receptor micro1 (OPRM1) Asn40Asp, which may serve as a gatekeeper molecule in the action of naltrexone, a drug used in alcoholism treatment; and HTTLPR, which alters serotonin transporter function and appears to affect stress response and anxiety/dysphoria, which are factors relevant to initial vulnerability, the process of addiction, and relapse.

  4. ALCOHOL AND HEART RHYTHM DISORDERS

    2015-01-01

    Full Text Available Alcohol abuse and particularly extension of alcohol consumption in alcohol diseas increases the risk of cardiac arrhythmias development and aggravates existing arrhythmias. Patients do not always receive the necessary specific treatment due to lack of detection of the ethanol genesis of these arrhythmias. Management of patients with alcohol abuse and alcohol dependence, including its cardiac complications among other cardiac arrhythmias should use both antiarrhythmic and anti-alcohol drugs and antidepressants. Such issues as diagnosis and management of patients with alcohol-induced cardiac arrhythmias are presented.

    Chronic alcohol consumption negatively affects health, and has additional consequences if consumption occurs during pregnancy as prenatal alcohol exposure adversely affects offspring development. While much is known on the effects of prenatal alcohol exposure in offspring less is known about effects of alcohol in dams. Here, we examine whether chronic alcohol consumption during gestation alters maternal behavior, hippocampal neurogenesis and HPA axis activity in late postpartum female rats compared with nulliparous rats. Rats were assigned to alcohol, pair-fed or ad libitum control treatment groups for 21 days (for pregnant rats, this occurred gestation days 1-21). Maternal behavior was assessed throughout the postpartum period. Twenty-one days after alcohol exposure, we assessed doublecortin (DCX) (an endogenous protein expressed in immature neurons) expression in the dorsal and ventral hippocampus and HPA axis activity. Alcohol consumption during pregnancy reduced nursing and increased self-directed and negative behaviors, but spared licking and grooming behavior. Alcohol consumption increased corticosterone and adrenal mass only in nulliparous females. Surprisingly, alcohol consumption did not alter DCX-expressing cell density. However, postpartum females had fewer DCX-expressing cells (and of these cells more immature proliferating cells but fewer postmitotic cells) than nulliparous females. Collectively, these data suggest that alcohol consumption during pregnancy disrupts maternal care without affecting HPA function or neurogenesis in dams. Conversely, alcohol altered HPA function in nulliparous females only, suggesting that reproductive experience buffers the long-term effects of alcohol on the HPA axis.

    Americium is similar to light rare earths in solvent extraction by HEHEHP.So the fractional extraction process with three outlets,which is widely used on rare earth industrial scale,can be applied to separate Am from La,Ce,Pr,Nd and Sm.The better process parameters can be calculated by the material and distribution balance equations stage by stage with given organic loading.In order to recover 0.99 mole fraction of Am and remove 0.90 mole fraction of light rare earths from the feed solution,in which the mole ratios of La Ce,Am,Pr,Nd,Sm are 0.140,0.199,0.005,0.109,0.487,0.060,the total number of stages needed is 43,that is the extraction sector 18,first scrubbing sector 2 and second scrubbing sector 23.The fractional extraction process with three outlets is simpler and more convenient than two fractional extraction processes with two outltes.

  7. Flow dynamical behavior and performance of a micro viscous pump with unequal inlet and outlet areas

    Directory of Open Access Journals (Sweden)

    Chenhui Hu

    2016-01-01

    Full Text Available The micro viscous pump is an important type of fluidic device. Optimizing the working performance of the pump is crucial for its wider application. A micro viscous pump design with unequal inlet and outlet areas is proposed in this paper. The flow field of the viscous pump is investigated using 2D laminar simulations. The mass flow rate and driving power are studied with different opening angles. The effects of the Reynolds number and the pressure load on the working performance are discussed in detail. Flow structures and vortex evolution are analyzed. With larger inlet and outlet areas, a higher mass flow rate is obtained and less driving power is achieved. A high pressure load results in a reduction in mass flow rate and an increase in driving power. Pumps with large opening angles are more susceptive to the Reynolds number and the pressure load. The adverse impact of the pressure load can be reduced by increasing the rotor speed. The vortex structure is affected by the geometric and operating parameters in the flow field. The flow dynamical behavior of the viscous pump exerts significant influence on its pumping ability. The present work gives rise to performance improvements for the micro viscous pump.

    Full Text Available Background. Self-expandable metal stents (SEMs are increasingly being utilised instead of invasive surgery for the palliation of patients with malignant gastroduodenal outlet obstruction. Aim. To review two tertiary centres’ experience with placement of SEMs and clinical outcomes. Methods. Retrospective analysis of prospectively collected data over 12 years. Results. Ninety-four patients (mean age, 68; range 28–93 years underwent enteral stenting during this period. The primary tumour was gastric adenocarcinoma in 27 (29% patients, pancreatic adenocarcinoma in 45 (48%, primary duodenal adenocarcinoma in 8 (9%, and cholangiocarcinoma and other metastatic cancers in 14 (16%. A stent was successfully deployed in 95% of cases. There was an improvement in gastric outlet obstruction score (GOOS in 84 (90% of patients with the ability to tolerate an enteral diet. Median survival was 4.25 months (range 0–49 without any significant differences between types of primary malignancy. Mean hospital stay was 3 days (range 1–20. Reintervention rate for stent related complications was 5%. Conclusion. The successful deployment of enteral stents achieves excellent palliation often resulting in the prompt reintroduction of enteral diet and early hospital discharge with minimal complications and reintervention.

  9. A Numerical Analysis of Droplet Breakup in Asymmetric T-Junctions with Different Outlet Pressure Gradients

    Cheng, Way Lee; Han, Arum; Sadr, Reza

    2016-11-01

    Droplet splitting is the breakup of a parent droplet into two or more daughter droplets of desired sizes. It is done to improve production efficiency and investigational capacity in microfluidic devices. Passive splitting is the breakup of droplets into precise volume ratios at predetermined locations without external power sources. In this study, a 3-D simulation was conducted using the Volume-of-Fluid method to analysis the breakup process of a droplet in asymmetric T-junctions with different outlet arm lengths. The arrangement allows a droplet to be split into two smaller droplets of different sizes, where the volumetric ratio of the daughter droplets depends on the length ratios of the outlet arms. The study identified different breakup regimes such as primary, transition, bubble and non-breakup under different flow conditions and channel configurations. Furthermore, a close analysis to the primary breakup regimes were done to determine the breakup mechanisms at various flow conditions. The analysis show that the breakup mechanisms in asymmetric T-junctions is different than a regular split. A pseudo-phenomenological model for the breakup criteria was presented at the end. The model was an expanded version to a theoretically derived model for the symmetric droplet breakup. The Qatar National Research Fund (a member of the Qatar Founda- tion), under Grant NPRP 5-671-2-278, supported this work.

    In this work, a reliable and robust vacuum-outlet gas chromatography-mass spectrometry (GC-MS) method is introduced for the identification and quantification of impurities in trinitrotoluene (TNT). Vacuum-outlet GC-MS allows for short analysis times; the analysis of impurities in TNT was performed in 4min. This study shows that impurity profiling of TNT can be used to investigate relations between TNT samples encountered in forensic casework. A wide variety of TNT samples were analyzed with the developed method. Dinitrobenzene, dinitrotoluene, trinitrotoluene and amino-dinitrotoluene isomers were detected at very low levels (<1wt.%) by applying the MS in selected-ion monitoring (SIM) mode. Limits of detection ranged from 6ng/mL for 2,6-dinitrotoluene to 43ng/mL for 4-amino-2,6-dinitrotoluene. Major impurities in TNT were 2,4-dinitrotoluene and 2,3,4-trinitrotoluene. Impurity profiles based on seven compounds showed to be useful to TNT samples from different sources. Statistical analysis of these impurity profiles using likelihood ratios demonstrated the potential to investigate whether two questioned TNT samples encountered in forensic casework are from the same source.

    2009-01-01

      Sociological studies into alcohol use seem to find it difficult to deal with the substance itself. Alcohol tends to be reduced to a symbol of a social process and in this way the sociological research loses sight of effects beyond the social. This paper suggests a new theoretical approach...... to the study of alcohol and teenagers' (romantic) relationships, inspired by actor-network theory (ANT). The central feature of ANT is to search for relationships, or rather networks, between all things relevant to the phenomenon. All material and semantic structures, things, persons, discourses, etc....... that influence a given situation are described as actants and are entered into the analysis. The aim of this paper is to propose a way of including materiality in sociological analyses of alcohol and to explore ways of using focus group interview material in ANT-inspired analysis.

    Full Text Available Single-blade centrifugal impellers for sewage systems undergo both unsteady radial and axial thrusts. Therefore, it is extremely important for the improvement of pump reliability to quantitatively grasp these fluctuating hydrodynamic forces and determine the generation mechanism behind them. In this study, we conducted component analyses of radial and axial thrusts of closed, single-blade centrifugal pumps with different blade outlet angles by numerical analysis while considering leakage flow. The results revealed the effect of the blade outlet angle on the components of radial and axial thrusts. For increased flow rates, the time-averaged values of the pressure component were similar for all impellers, although its fluctuating components were higher for impellers with larger blade outlet angles. Moreover, the fluctuating inertia component of the impeller with a blade outlet angle of 8° decreased as the flow rate increased, whereas those with 16° and 24° angles increased. Therefore, the radial thrust on the hydraulic part was significantly higher for impellers with high blade outlet angles.

    The aim of the study was to quantify alcohol-attributable and -preventable mortality, totally and stratified on alcohol consumption in Denmark 2010, and to estimate alcohol-related mortality assuming different scenarios of changes in alcohol distribution in the population. We estimated alcohol......-attributable and -preventable fractions based on relative risks of conditions causally associated with alcohol from meta-analyses and information on alcohol consumption in Denmark obtained from 14,458 participants in the Danish National Health Survey 2010 and corrected for adult per capita consumption. Cause-specific mortality...... data were obtained from the Danish Register of Causes of Death. In total, 1,373 deaths among women (5.0 % of all deaths) and 2,522 deaths among men (9.5 % of all deaths) were attributable to alcohol, while an estimated number of 765 (2.8 %) and 583 (2.2 %) deaths were prevented by alcohol...

    BACKGROUND & AIMS: Alcohol is the main contributing factor of alcoholic cirrhosis, but less is known about the significance of drinking pattern. METHODS: We investigated the risk of alcoholic cirrhosis among 55,917 participants (aged 50-64 years) in the Danish Cancer, Diet, and Health study (1993......-2011). Baseline information on alcohol intake, drinking pattern, and confounders was obtained from a questionnaire. Follow-up information came from national registers. We calculated hazard ratios (HRs) for alcoholic cirrhosis in relation to drinking frequency, lifetime alcohol amount, and beverage type. RESULTS......: We observed 257 and 85 incident cases of alcoholic cirrhosis among men and women, respectively, none among lifetime abstainers. In men, HR for alcoholic cirrhosis among daily drinkers was 3.65 (95% CI: 2.39; 5.55) compared to drinking 2-4 days/week. Alcohol amount in recent age periods (40-49 and 50...

    Mounting evidence over the last 40 years clearly indicates that alcoholism (alcohol dependence) is a disorder of the brain. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) has taken significant steps to advance research into the neuroscience of alcohol. The Division of Neuroscience and Behavior (DNB) was formed within NIAAA in 2002 to oversee, fund, and direct all research areas that examine the effects of alcohol on the brain, the genetic underpinnings of alcohol dependence, the neuroadaptations resulting from excessive alcohol consumption, advanced behavioral models of the various stages of the addiction cycle, and preclinical medications development. This research portfolio has produced important discoveries in the etiology, treatment, and prevention of alcohol abuse and dependence. Several of these salient discoveries are highlighted and future areas of neuroscience research on alcohol are presented.

    Full Text Available BACKGROUND: Mammographic density is a strong risk factor for breast cancer. Apart from hormone replacement therapy (HRT, little is known about lifestyle factors that influence breast density. METHODS: We examined the effect of smoking, alcohol and physical activity on mammographic density in a population-based sample of postmenopausal women without breast cancer. Lifestyle factors were assessed by a questionnaire and percentage and area measures of mammographic density were measured using computer-assisted software. General linear models were used to assess the association between lifestyle factors and mammographic density and effect modification by body mass index (BMI and HRT was studied. RESULTS: Overall, alcohol intake was positively associated with percent mammographic density (P trend  = 0.07. This association was modified by HRT use (P interaction  = 0.06: increasing alcohol intake was associated with increasing percent density in current HRT users (P trend  = 0.01 but not in non-current users (P trend  = 0.82. A similar interaction between alcohol and HRT was found for the absolute dense area, with a positive association being present in current HRT users only (P interaction  = 0.04. No differences in mammographic density were observed across categories of smoking and physical activity, neither overall nor in stratified analyses by BMI and HRT use. CONCLUSIONS: Increasing alcohol intake is associated with an increase in mammography density, whereas smoking and physical activity do not seem to influence density. The observed interaction between alcohol and HRT may pose an opportunity for HRT users to lower their mammographic density and breast cancer risk.

    This study identified heterogeneous classes of alcohol-related neighborhood characteristics to which multi-ethnic, early adolescents in urban communities are exposed. The sample comprised 4,215 youth from 42 community areas in Chicago, Illinois who completed surveys at the beginning of 6th grade (2002). Neighborhood measures included: (1) mean number of alcohol outlets per 1,000 population per community area; (2) alcohol purchase attempt rate by pseudo-underage youth; (3) average number of alcohol advertisements within 1,500 feet of each school per community; and (4) a Census 2000-based deprivation index. Parents and community leaders provided data on perceived neighborhood problems and parental prevention actions, and neighborhood strength and preventive action by communities, law enforcement, and community organizations, respectively. Multilevel latent class analysis identified the number and characteristics of heterogeneous latent neighborhood classes in which these youth are exposed. Five classes best described the heterogeneity among the sample: (1) Low social capital/low exposure/high access to alcohol (19.8%), (2) Low social capital/low exposure/low access to alcohol (24.5%), (3) Moderate social capital/low exposure/high access to alcohol (30.0%), (4) Moderate social capital/moderate exposure/low access to alcohol (20.1%), and (5) High social capital/moderate exposure/high access to alcohol (5.6%). The racial/ethnic distribution among the classes varied considerably. Results suggest there is substantive heterogeneity among this seemingly homogeneous urban population. Further, they highlight the socioeconomic disadvantage of these inner-city communities and the resource disparity across the racial/ethnic groups. Understanding the nuances among communities may lend to development of more efficacious preventive interventions and policy initiatives, inform theory, and help prioritize limited resources.

    Norway's controversial Alta hydroelectric power plant was constructed on one of the richest salmon rivers in Norway. There were serious concerns regarding how the power plant would influence ice conditions and fish habitat in the river. It was commissioned in 1987 following extensive environmental impact studies. Studies on water temperature, ice conditions and fish population have continued after commissioning in order to document changes caused by the power plant. The power station has two intakes in the dam. The storage capacity is 6 per cent of yearly inflow to the reservoir. The outlet of the power plant is located 2 km downstream the dam. The power plant discharge has been limited to 30 m{sup 3}/s in winter and as close as possible to natural flow during the fishing season. The reservoir is filled over a 2 to 3 week period during spring flood. Initially, only one intake to the power station was planned, but an upper intake was subsequently built to minimize the impact on fish, although the effect has been marginal. Before flow regulation, the river was ice covered except for limited leads. Flow regulation has reduced the ice cover considerably, and the water temperature has been slightly lower in summer and higher in fall and winter. After flow regulation, the amount of fish near the power station outlet decreased considerably, due in part to less shelter resulting from reduced ice cover. In order to improve conditions for the fish, the licence for the power plant is being modified to use the upper intake in winter to reduce water temperatures and make it possible for ice to form between the outlet of the power plant and Savko Lake. There are strong limitations on reductions in discharge in spring to protect the fish habitat. A new scheme of regulation based on use of the upper intake in winter will be implemented. The discharge must be increased in such a way that the ice release will be as close to thermal as possible. 3 refs., 7 figs.

    In order to analyze the influence of the air outlet louver on the noise generated by the outdoor set of a split-unit air conditioner, the flow field in the outdoor set is simulated with the CFD software STAR-CD. The relative turbulent intensities are computed and the influence of the shape and the steel wire diameter of the air outlet louver on the noise generated by the outdoor set is analyzed. The results of computation and experiment show that the circular shape of air outlet louver gives benefit of noise decrease. An air outlet louver with different diameters of steel wires is designed on the basis of analysis of the influence of the steel wire diameter of the air outlet louver on the noise. The computation and experiment validate that the air outlet louver with different diameters of steel wires can improve the aerodynamic performance and reduce the noise generated by the outdoor set.

    Full Text Available CONTEXT: The oropharynx microbiota plays an important role in the origin of infections, especially among alcoholics whose airway defenses are impaired. OBJECTIVE: To compare the normal oropharingeal flora in heavy alcohol drinker and non-alcoholics. PATIENTS: 117 persons, 58 heavy alcohol drinkers and 59 non-alcoholics. SETTING: Santa Casa de São Paulo Emergency Service. DESIGN: A blind prospective study. MAIN OUTCOMES MEASURES: Prevalence of aerobic and anaerobic bacteria, and fungi. RESULTS: The study of the oropharynx microbiota among heavy alcohol drinkers demonstrated the presence of anaerobic microorganisms in 84.5% of them, including: Bacteroides sp, Prevotella melaninogenica, Fusobacterium sp, Veilonella sp, Peptostreptococcus sp, Propionibacterium sp, Bifidobacterium sp and Clostridium sp, versus 30.5% (p<0.005 of non-alcoholics. Candida sp was present in 34.5% of heavy alcohol drinkers and 5.1% of non-alcoholics (p<0.005. Enterobacteria predominated among heavy alcohol drinkers (25% compared with non-alcoholics (5.5% only in the age group 14 to 34 years (p<0.05. CONCLUSION: Based upon these results, it was possible to conclude that the knowledge of the oropharynx microbiota among heavy drinkers and non-alcoholics has an important predictive value concerning probable etiologic agents of lower airway infections. Infections caused by anaerobic microorganisms and fungi should be taken into consideration during the choice of empirical therapy for heavy alcohol drinkers.

    Full Text Available Problem statement: The growth of food outlets in Malaysia brings about the stiff competition among the players in food industry. To remain competitive, each outlet needs to adopt its own strategy in order to secure their return on investment and profitability. In knowledge era, technology has become an added value in achieving competitive advantage. The aim of this research is to assess whether providing free WiFi can be a strategy to remain competitive. Porter's 5forces competitive model is adopted as the basis for the assessment. Approach: Two phases of data collection using qualitative methodology were planned and rolled out. The first phase involved surveying and observing three regions within a selected state, while the second phase involved interviewing the identified food outlet’s manager. A set of interview questions was formulated based on the 5 areas of porter's model which includes bargaining power of suppliers, bargaining power of customers, threat of substitutions, threat of new entrants and existing rivalries. In addition to the existing five forces, information regarding government policy and initiatives was also collected. Results: Result has shown that by that offering free WiFi to meet the customers' needs, it can help to generate revenue increase of as high as 50% thus ensuring the food outlet to stay competitive. Conclusion: This is more visible when dealing with case of food outlets at same area are targeting the same group of customers as what had been observed in this research. This research provides a good reference to other food outlets that yet to adopt any strategy in order to stay competitive.

    Alternative transportation fuels, preferably from renewable sources, include alcohols with up to five or even more carbon atoms. They are considered promising because they can be derived from biological matter via established and new processes. In addition, many of their physical-chemical properties are compatible with the requirements of modern engines, which make them attractive either as replacements for fossil fuels or as fuel additives. Indeed, alcohol fuels have been used since the early years of automobile production, particularly in Brazil, where ethanol has a long history of use as an automobile fuel. Recently, increasing attention has been paid to the use of non-petroleum-based fuels made from biological sources, including alcohols (predominantly ethanol), as important liquid biofuels. Today, the ethanol fuel that is offered in the market is mainly made from sugar cane or corn. Its production as a first-generation biofuel, especially in North America, has been associated with publicly discussed drawbacks, such as reduction in the food supply, need for fertilization, extensive water usage, and other ecological concerns. More environmentally friendly processes are being considered to produce alcohols from inedible plants or plant parts on wasteland. While biofuel production and its use (especially ethanol and biodiesel) in internal combustion engines have been the focus of several recent reviews, a dedicated overview and summary of research on alcohol combustion chemistry is still lacking. Besides ethanol, many linear and branched members of the alcohol family, from methanol to hexanols, have been studied, with a particular emphasis on butanols. These fuels and their combustion properties, including their ignition, flame propagation, and extinction characteristics, their pyrolysis and oxidation reactions, and their potential to produce pollutant emissions have been intensively investigated in dedicated experiments on the laboratory and the engine scale

    For invertebrates to become useful models for understanding the genetic and physiological mechanisms of alcoholism related behaviors and the predisposition towards alcoholism, several general requirements must be fulfilled. The animal should encounter ethanol in its natural habitat, so that the central nervous system of the organism will have evolved mechanisms for responding to ethanol exposure. How the brain adapts to ethanol exposure depends on its access to ethanol, which can be regulated metabolically and/or by physical barriers. Therefore, a model organism should have metabolic enzymes for ethanol degradation similar to those found in humans. The neurons and supporting glial cells of the model organism that regulate behaviors affected by ethanol should share the molecular and physiological pathways found in humans, so that results can be compared. Finally, the use of invertebrate models should offer advantages over traditional model systems and should offer new insights into alcoholism-related behaviors. In this review we will summarize behavioral similarities and identified genes and mechanisms underlying ethanol-induced behaviors in invertebrates. This review mainly focuses on the use of the nematode Caenorhabditis elegans, the honey bee Apis mellifera and the fruit fly Drosophila melanogaster as model systems. We will discuss insights gained from those studies in conjunction with their vertebrate model counterparts and the implications for future research into alcoholism and alcohol-induced behaviors.

  11. Diabetes mellitus and alcohol.

    Alcohol influences glucose metabolism in several ways in diabetic patients as well as in non-diabetic patients. Since alcohol inhibits both gluconeogenesis and glycogenolysis, its acute intake without food may provoke hypoglycaemia, especially in cases of depleted glycogen stores and in combination with sulphonylurea. Consumed with a meal including carbohydrates, it is the preferred fuel, which may initially lead to somewhat higher blood glucose levels and hence an insulin response in type 2 diabetic patients. Depending on the nature of the carbohydrates in the meal, this may be followed by reactive hypoglycaemia. Moderate consumption of alcohol is associated with a reduced risk of atherosclerotic disorders. Diabetic patients benefit from this favourable effect as much as non-diabetic patients. Apart from effects on lipid metabolism, haemostatic balance and blood pressure, alcohol improves insulin sensitivity. This improvement of insulin sensitivity may also be responsible for the lower incidence of type 2 diabetes mellitus reported to be associated with light-to-moderate drinking. In case of moderate and sensible use, risks of disturbances in glycaemic control, weight and blood pressure are limited. Excessive intake of alcohol, however, may not only cause loss of metabolic control, but also annihilate the favourable effects on the cardiovascular system.

  12. Stress, epigenetics, and alcoholism.

    Acute and chronic stressors have been associated with alterations in mood and increased anxiety that may eventually result in the development of stress-related psychiatric disorders. Stress and associated disorders, including anxiety, are key factors in the development of alcoholism because alcohol consumption can temporarily reduce the drinker's dysphoria. One molecule that may help mediate the relationship between stress and alcohol consumption is brain-derived neurotrophic factor (BDNF), a protein that regulates the structure and function of the sites where two nerve cells interact and exchange nerve signals (i.e., synapses) and which is involved in numerous physiological processes. Aberrant regulation of BDNF signaling and alterations in synapse activity (i.e., synaptic plasticity) have been associated with the pathophysiology of stress-related disorders and alcoholism. Mechanisms that contribute to the regulation of genetic information without modification of the DNA sequence (i.e., epigenetic mechanisms) may play a role in the complex control of BDNF signaling and synaptic plasticity-for example, by modifying the structure of the DNA-protein complexes (i.e., chromatin) that make up the chromosomes and thereby modulating the expression of certain genes. Studies regarding the epigenetic control of BDNF signaling and synaptic plasticity provide a promising direction to understand the mechanisms mediating the interaction between stress and alcoholism.

    Multiple lines of evidence strongly indicate that genetic factors contribute to the risk for alcohol use disorders (AUD). There is substantial heterogeneity in AUD, which complicates studies seeking to identify specific genetic factors. To identify these genetic effects, several different alcohol-related phenotypes have been analyzed, including diagnosis and quantitative measures related to AUDs. Study designs have used candidate gene analyses, genetic linkage studies, genomewide association studies (GWAS), and analyses of rare variants. Two genes that encode enzymes of alcohol metabolism have the strongest effect on AUD: aldehyde dehydrogenase 2 and alcohol dehydrogenase 1B each has strongly protective variants that reduce risk, with odds ratios approximately 0.2-0.4. A number of other genes important in AUD have been identified and replicated, including GABRA2 and alcohol dehydrogenases 1B and 4. GWAS have identified additional candidates. Rare variants are likely also to play a role; studies of these are just beginning. A multifaceted approach to gene identification, targeting both rare and common variations and assembling much larger datasets for meta-analyses, is critical for identifying the key genes and pathways important in AUD.

    We present a case of complete vaginal stenosis in a woman diagnosed with Sheehan’s syndrome. The patient delivered at full-term 5 months prior, and experienced massive postpartum bleeding at that time. During evaluation of persistent amenorrhea, we found that her vaginal orifice was completely adhesive and obstructed. Prior to corrective surgery, we managed the patient with an oral contraceptive to induce uterine bleeding into the vaginal outflow tract. After three cycles of an oral contraceptive, we could confirm that there was no stenotic lesion in the vaginal cavity as a hematocolpos was created. Adhesiolysis with scar revision for the vaginal stenosis was successfully performed; it was found that the lesion was limited to only the distal part of the vaginal outlet. Complete vaginal stenosis in reproductive age women with hypopituitarism has not been reported. The artificial induction of hematometrocolpos before surgery was useful in determining the extent of the stenotic lesion, and assured safety. PMID:27896263

    This project principally undertook the investigation of the thermal hydraulic performance of wire wrapped fuel bundles of LMFBR configuration. Results obtained included phenomenological models for friction factors, flow split and mixing characteristics; correlations for predicting these characteristics suitable for insertion in design codes; numerical codes for analyzing bundle behavior both of the lumped subchannel and distributed parameter categories and experimental techniques for pressure velocity, flow split, salt conductivity and temperature measurement in water cooled mockups of bundles and subchannels. Flow regimes investigated included laminar, transition and turbulent flow under forced convection and mixed convection conditions. Forced convections conditions were emphasized. Continuing efforts are underway at MIT to complete the investigation of the mixed convection regime initiated here. A number of investigations on outlet plenum behavior were also made. The reports of these investigations are identified.

    2013-04-01

    Transaxillary first rib resection is a well-established effective surgical treatment for patients with symptomatic thoracic outlet syndrome, but surgical access may be limited and visualization is constrained. The use of high-definition video-assisted imaging overcomes these limitations. The use of high-definition video-assisted visualization of the anatomy enhances the surgeon's tactile feedback of the rib from the small open wound and is effective in providing better surgical access and allows clear identification of vital structures for the operating surgical team. This technique enhances the appreciation of anatomic detail, situational awareness of the team, and allows for more efficient assistance to the surgeon. Improved visualization also facilitates effective education of nurses, residents, and students.

    A 2-year old intact male Collie dog presented to the cardiology service at Oregon State University for evaluation of cyanosis and suspected congenital cardiac disease. Echocardiography revealed a constellation of cardiac abnormalities including a single large vessel exiting the right ventricle with a diminutive left ventricular outflow tract, a ventricular septal defect, and marked concentric right ventricular hypertrophy with moderate right atrial dilation. Cardiac-gated computed tomography confirmed the previous anomalies in addition to supporting a diagnosis of complete transposition of the great arteries, double outlet right ventricle, and pulmonic hypoplasia with a single coronary ostium. Prominent bronchoesophageal collateral vessels were concurrently identified. Clinically, the dog was stable despite mild cyanosis that worsened with exercise; no intervention was elected at the time. This case report describes a rare combination of congenital cardiac defects and the usefulness of cardiac-gated cross-sectional imaging in the anatomic diagnosis.

    Objective. In a pilot study we evaluated whether implementation of a novel 3D stereologic technique can prove that bladder outlet obstruction (BOO) is associated with morphologic changes in the bladder wall. Material and methods. Ten males (mean age 69.7 years; range 58-84 years) with lower urinary...... tract symptoms (LUTS) suggestive of BOO and five controls (mean age 48.6 years; range 43-53 years) without LUTS were studied. All participants underwent a full examination, including determination of the International Prostate Symptom Score, laboratory analysis and a urodynamic evaluation. A cold....... Conclusions. This pilot study shows that, even with the implementation of subtle morphometric techniques, there seems to be no relationship between the severity of BOO and bladder wall morphology. It is possible that interstitial collagen in the bladder wall increases with age. It seems that bladder wall...

    Full Text Available Benign prostatic hyperplasia (BPH is a histological diagnosis associated with unregulated proliferation of connective tissue, smooth muscle and glandular epithelium. BPH may compress the urethra and result in anatomic bladder outlet obstruction (BOO; BOO may present as lower urinary tract symptoms (LUTS, infections, retention and other adverse events. BPH and BOO have a significant impact on the health of older men and health-care costs. As the world population ages, the incidence and prevalence of BPH and LUTS have increased rapidly. Although non-modifiable risk factors - including age, genetics and geography - play significant roles in the etiology of BPH and BOO, recent data have revealed modifiable risk factors that present new opportunities for treatment and prevention, including sex steroid hormones, the metabolic syndrome and cardiovascular disease, obesity, diabetes, diet, physical activity and inflammation. We review the natural history, definitions and key risk factors of BPH and BOO in epidemiological studies.

    Double-outlet right ventricle is defined as follows: both great arteries arise completely or nearly completely from the right ventricle; neither semilunar valve is in fibrous continuity with either atrioventricular valve; and usually a ventricular septal defect is present and the only outlet from the left ventricle. A total of 44 cases of double-outlet right ventricle is analyzed, in which cineangiocardiographies were done at the Department of Radiology, Seoul National University Hospital in recent 4 year and 6 months, with specific reference to the segmental combinations, the height of conus, the relationship of great arteries, the location of ventricular septal defects, and associated anomalies. The results were as follows; 1. Among 44 cases, 36 cases had normal cardiac position, 4 cases had dextrocardia with situs inversus 2 cases had dextrocardia with situs solitus, 1 case had levocardia with situs inversus, and another 1 case had mesocardia with situs ambiguus. 2. Segmental sets were [S,D,D] in 36 cases, [I,L,L] in 3 cases, [I,D,D] in 2 cases, [S,D,L], [S,L,L] and [A,D,D] in 1 case respectively. 3. All cases had bilateral conus. Aortic valve rings were same level as pulmonary valve rings in 25 cases, lower than pulmonary valve rings in 17 cases in which 15 cases were type A., and higher than pulmonary valve rings in 2 cases. 4. The relation of the great arteries were normal in 15 cases, side-by-side in 13 cases, dextromalposition in 13 cases, and levomal position in 3 cases. 5. The position of the ventricular septal defects with respect to the origins of the great arteries is subaortic (type A and type B) in 23 cases, subpulmonary (type C) in 13 cases, doubly committed (type D) in 3 cases, and uncommitted (type E) in 5 cases. 6. Associated cardiac malformations are pulmonary stenosis in 24 which had all cases of type A and type E, aortic stenosis in 6 which were only in type C, left SVC in 6, abnormality of atrioventricular valve in 5, single coronary artery

    Full Text Available Changes in the degree of habitat moisture are one of the major factors affecting the variability of plant communities and their constituent species populations. The aim of the study was to find if the quantitative and qualitative structure of the vegetation cover exhibits variability in relation to the degree of habitat moisture. The investigations were carried out in basin without outlets, i.e. small isolated hydrogenic object located in the agricultural landscape of the Lublin Upland. In basin, a transect was established, along which floristic inventories were made. In the years 2006–2013, the level of surface water were monitored. On this basis, four areas of habitat moisture were identified. The results indicate that the flora of the analysed object is characterised by a very broad spectrum of ecological tolerance. The vegetation cover is influenced by habitat moisture whose gradient determines the occurrence range of many species.

    2012-01-01

    Full Text Available We report an adolescent girl who had left-sided neurogenic thoracic outlet syndrome (TOS due to impingement of the scalenus anterior muscle with bilateral changes on nerve conduction studies and responded well to surgical decompression. A 13-year-old Caucasian girl presented with intermittent pain, swelling, erythema, tingling and numbness of the palmar aspect of her left hand. Nerve conduction studies revealed bilateral ulnar sensory and motor conduction abnormalities, suggesting early compressive neuropathy in the asymptomatic arm as well. She underwent surgical exploration when it was noted that the scalenus anterior itself was impinging on the brachial plexus. She had a good clinical response to scalenectomy. The diagnosis of neurogenic TOS remains difficult as no single test has been accepted as a gold standard. But, once diagnosed using clinical symptoms, nerve conduction studies, electromyography and radiological investigations, it is a treatable condition with good prognosis.

    Repeat surveys by aircraft laser altimeter in 1993/4 and 1998/9 reveal significant thinning along 70% of the coastal parts of the Greenland ice sheet at elevations below about 2000 m. Thinning rates of more than 1 m/yr are common along many outlet glaciers, at all latitudes and, in some cases, at elevations up to 1500 m. Warmer summers along parts of the coast may have caused a few tens of cm/yr additional melting, but most of the observed thinning probably results from increased glacier velocities and associated creep rates. Three glaciers in the northeast all show patterns of thickness change indicative of surging behavior, and one has been independently documented as a surging glacier. There are a few areas of significant thickening (over 1 m/yr), and these are probably related to higher than normal accumulation rates during the observation period.

    2016-01-01

    Background: Greater exposures to fast-food outlets and lower levels of education are independently associated with less healthy diets and obesity. Little is known about the interplay between these environmental and individual factors. Objective: The purpose of this study was to test whether observed differences in fast-food consumption and obesity by fast-food outlet exposure are moderated by educational attainment. Design: In a population-based cohort of 5958 adults aged 29–62 y in Cambridgeshire, United Kingdom, we used educational attainment–stratified regression models to estimate the food-frequency questionnaire–derived consumption of energy-dense “fast foods” (g/d) typically sold in fast-food restaurants and measured body mass index (BMI; in kg/m2) across geographic information system–derived home and work fast-food exposure quartiles. We used logistic regression to estimate the odds of obesity (BMI ≥30) and calculated relative excess risk due to interaction (RERI) on an additive scale. Participant data were collected during 2005–2013 and analyzed in 2015. Results: Greater fast-food consumption, BMI, and odds of obesity were associated with greater fast-food outlet exposure and a lower educational level. Fast-food consumption and BMI were significantly different across education groups at all levels of fast-food outlet exposure (P < 0.05). High fast-food outlet exposure amplified differences in fast-food consumption across levels of education. The relation between fast-food outlet exposure and obesity was only significant among those who were least educated (OR: 2.05; 95% CI: 1.08, 3.87; RERI = 0.88), which suggested a positive additive interaction between education and fast-food outlet exposure. Conclusion: These findings suggest that efforts to improve diets and health through neighborhood-level fast-food outlet regulation might be effective across socioeconomic groups and may serve to reduce observed socioeconomic inequalities in diet and

    In February 1996 Salmonella enterica serotype Montevideo infection in a patient in the North Tyneside area was attributed to consumption of cooked chicken bought from a supermarket hot food outlet. Isolates from the patient, leftover food, and environmental samples were indistinguishable by pulsed field gel electrophoresis (PFGE). PFGE also demonstrated that an outbreak of infection with S. Montevideo associated with the hot food outlet had occurred in late 1995 and early 1996. This study shows the importance of microbial strain discrimination in outbreak investigations and illustrates the value of close liaison between microbiologists, epidemiologists, and environmental health officers in the control of salmonella outbreaks.

    A large part of the ice discharge from ice caps and ice sheets occurs through spatially limited flow units that may operate in a mode of steady flow or cyclic surge behaviour. Changes in the dynamics of distinct flow units play a key role in the mass balance of Austfonna, the largest ice cap on Svalbard. The recent net mass loss of Austfonna was dominated by calving from marine terminating outlet glaciers. Previous ice-surface velocity maps of the ice cap were derived by satellite radar interferometry (InSAR) and rely on data acquired in the mid-1990s with limited information concerning the temporal variability. Here, we present continuous Global Positioning System (GPS) observations along the central flowlines of two fast flowing outlet glaciers over 2008-2010. The data show prominent summer speed-ups with ice-surface velocities as high as 240 % of the pre-summer mean. Acceleration follows the onset of the summer melt period, indicating enhanced basal motion due to input of surface meltwater into the subglacial drainage system. In 2008, multiple velocity peaks coincide with successive melt periods. In 2009, the principle melt was of higher amplitude than in 2008. Flow velocities appear unaffected by subsequent melt periods, suggesting a transition towards a hydraulically more efficient drainage system. The observed annual mean velocities of Duvebreen and Basin-3 exceed those from the mid-1990s by factors two and four, respectively, implying increased ice discharge at the calving front. Measured summer velocities up to 2 m d-1 for Basin-3 are close to that of Kronebreen, often referred to as the fastest glacier on Svalbard.

    AIM: To investigate and evaluate the technical feasibility and clinical effectiveness of fluoroscopically guided peroral uncovered expandable metal stent placement to treat gastric outlet and duodenal obstructions. METHODS: Fifteen consecutive patients underwent peroral placement of WallstentTM Enteral Endoprosthesis to treat gastric outlet and duodenal obstructions (14 malignant, 1 benign). All procedures were completed under fluoroscopic guidance without endoscopic assistance. Follow-up was completed until the patients died or were lost, and the clinical outcomes were analyzed. RESULTS: The technique success rate was 100%, and the oral intake was maintained in 12 of 14 patients varying from 7 d to 270 d. Two patients remained unable to resume oral intake, although their stents were proven to be patent with the barium study. One patient with acute necrotizing pancreatitis underwent enteral stenting to treat intestinal obstruction, and nausea and vomiting disappeared. Ten patients died during the followup period, and their mean oral intake time was 50 d. No procedure-related complications occurred. Stent migration to the gastric antrum occurred in one patient 1 year after the procedure, a tumor grew at the proximal end of the stent in another patient 38 d post-stent insertion. CONCLUSION: Fluoroscopically guided peroral metal stent implantation is a safe and effective method to treat malignant gastrointestinal obstructions, and complications can be ignored based on our short-term study. Indications for this procedure should be discreetly considered because a few patients may not benefit from gastrointestinal insertion, but some benign gastrointestinal obstructions can be treated using this procedure.

    Diseases and conditions affecting the lower urinary tract are a leading cause of dysfunctional sexual health, incontinence, infection, and kidney failure. The growth, differentiation, and repair of the bladder's epithelial lining are regulated, in part, by fibroblast growth factor (FGF)-7 and -10 via a paracrine cascade originating in the mesenchyme (lamina propria) and targeting the receptor for FGF-7 and -10 within the transitional epithelium (urothelium). The FGF-7 gene is located at the 15q15-q21.1 locus on chromosome 15 and four exons generate a 3.852-kb mRNA. Five duplicated FGF-7 gene sequences that localized to chromosome 9 were predicted not to generate functional protein products, thus validating the use of FGF-7-null mice as an experimental model. Recombinant FGF-7 and -10 induced proliferation of human urothelial cells in vitro and transitional epithelium of wild-type and FGF-7-null mice in vivo.To determine the extent that induction of urothelial cell proliferation during the bladder response to injury is dependent on FGF-7, an animal model of partial bladder outlet obstruction was developed. Unbiased stereology was used to measure the percentage of proliferating urothelial cells between obstructed groups of wild-type and FGF-7-null mice. The stereological analysis indicated that a statistical significant difference did not exist between the two groups, suggesting that FGF-7 is not essential for urothelial cell proliferation in response to partial outlet obstruction. In contrast, a significant increase in FGF-10 expression was observed in the obstructed FGF-7-null group, indicating that the compensatory pathway that functions in this model results in urothelial repair.

    Hydrogen-bonded liquids play a significant role in numerous chemical and biological phenomena. In the past decade, impressive developments in multidimensional vibrational spectroscopy and combined molecular dynamics–quantum mechanical simulation have established many intriguing features of hydrogen bond dynamics in one of the fundamental solvents in nature, water. The next class of a hydrogen-bonded liquid—alcohols—has attracted much less attention. This is surprising given such important differences between water and alcohols as the imbalance between the number of hydrogen bonds, each molecule can accept (two) and donate (one) and the very presence of the hydrophobic group in alcohols. Here, we use polarization-resolved pump-probe and 2D infrared spectroscopy supported by extensive theoretical modeling to investigate hydrogen bond dynamics in methanol, ethanol, and isopropanol employing the OH stretching mode as a reporter. The sub-ps dynamics in alcohols are similar to those in water as they are determined by similar librational and hydrogen-bond stretch motions. However, lower density of hydrogen bond acceptors and donors in alcohols leads to the appearance of slow diffusion-controlled hydrogen bond exchange dynamics, which are essentially absent in water. We anticipate that the findings herein would have a potential impact on fundamental chemistry and biology as many processes in nature involve the interplay of hydrophobic and hydrophilic groups.

    Two SIRS alcoholism models with relapse on networks with fixed and adaptive weight are introduced. The spread of alcoholism threshold [Formula: see text] is calculated by the next generation matrix method. For the model with fixed weight, we prove that when [Formula: see text] the alcohol free equilibrium is globally asymptotically stable, then the drinking crowd gradually disappear. When [Formula: see text], the alcoholism equilibrium is global attractivity, then the density of alcoholics will remain in a stable value. For the model with adaptive weight, we only make some numerical simulations. We also give two effective strategies. Our results show that the treatment of recuperator for stopping relapsing and preventing the susceptible people to drink are two effective measures to eliminate alcoholism problem, and preventing the susceptible people to drink is more effective when the proportion of recuperator to accept treatment is equal to the proportion of susceptible people to refuse drinking alcohol.

    There are wide ranging effects of alcohol on the nervous system. Some interfere with physiological and neurochemical functions but ultimately structural damage occurs. During life one of the most impressive changes is brain shrinkage which can be visualized using neuroradiological imaging techniques. This article reviews the pathological explanations for brain shrinkage and addresses the question of the pathogenesis of the reversible component of this damage in relation to prolonged abstinence from alcohol. This shrinkage seems to relate to a loss of white matter. However, the cortex is also abnormal in that there is a loss of neurones from the frontal region. In this and other regions of the cortex examined there is shrinkage of the neuronal soma. This is reflected in a retraction of the neuronal dendritic arbor which plays a crucial role in cell-to-cell communication. In addition, the cerebellum appears to be vulnerable in alcoholic patients although it may well be that associated nutritional deficiencies play an important role. The Wernicke-Korsakoff syndrome is another important deficiency disorder which is seen most frequently in alcoholic patients. Two important population groups which are considered in this review are females and moderate ('social') drinkers. Females are thought to be more susceptible to the damaging effects of alcohol than males and this is examined in the light of the scant data available. Similarly, there are few neuropathological data on people who drink 30-80 grams of alcohol per day. In order to assess so-called 'safe levels of drinking' this is an important group to study.

    Full Text Available While there seems to be growing media intrigue over atypical forms of alcohol use, the utilization of the majority of novel consumption methods (e.g., eyeballing, slimming, alcohol without liquid (AWOL seems minimal. In 2014, however, several outlets suggested that powdered alcohol would soon surface as a threat to public safety. The impetus of these fears was the Alcohol and Tobacco Tax and Trade Bureau’s approval for Lipsmark LLC to package a powdered alcohol product named “Palcohol”. Palcohol has yet to reach store shelves, but public outcry has been intense. Despite this reaction, little is known about whether the population will consider Palcohol a suitable alternative to traditional alcohol, particularly given its excessive predicted cost. In an exploratory effort to assess perceptions, use intentions, and fears related to Palcohol, 31 young adults were asked to view a 16-minute video about Palcohol and answer a series of questions about Palcohol, including whether and how they intend to use it. Results suggest that young adults intend to experiment with Palcohol following its release, but they have a number of concerns. While few expect to become habitual users of the product, many believe it will enable people to utilize alcohol in settings where its consumption is prohibited.

  9. Coupling and Reactions of 5-Hydroxyconiferyl Alcohol in Lignin Formation

    Energy Technology Data Exchange (ETDEWEB)

    2016-06-15

    The catechol alcohols, caffeyl and 5-hydroxyconiferyl alcohol, may be incorporated into lignin either naturally or through genetic manipulation. Due to the presence of o-OH groups, these compounds form benzodioxanes, a departure from the interunit connections found in lignins derived from the cinnamyl alcohols. In nature, lignins composed of caffeyl and 5-hydroxyconiferyl alcohol are linear homopolymers and, as such, may have properties that make them amenable for use in value-added products, such as lignin-based carbon fibers. In the current work, results from density functional theory calculations for the reactions of 5-hydroxyconiferyl alcohol, taking stereochemistry into account, are reported. Dehydrogenation and quinone methide formation are found to be thermodynamically favored for 5-hydroxyconiferyl alcohol, over coniferyl alcohol. The comparative energetics of the rearomatization reactions suggest that the formation of the benzodioxane linkage is under kinetic control. Ring-opening reactions of the benzodioxane groups show that the bond dissociation enthalpy of the ..alpha..-O cleavage reaction is lower than that of the ..beta..-O reaction. The catechol lignins represent a novel form of the polymer that may offer new opportunities for bioproducts and genetic targets.

    1982-01-01

    Polyvinly alcohol (PVA) cross-linked with aldehyde reagents yields membranes that demonstrate properties that make them suitable for use as alkaline battery separators. Film properties can be controlled by the choice of cross-linker, cross-link density and the method of cross-linking. Three methods of cross-linking and their effects on film properties are discussed. Film properties can also be modified by using a copolymer of vinyl alcohol and acrylic acid as the base for the separator and cross-linking it similarly to the PVA. Fillers can be incorporated into the films to further modify film properties. Results of separator screening tests and cell tests for several variations of PBA films are discussed.

    Full Text Available Abstract Introduction Gastric outlet obstruction is a clinical syndrome caused by a variety of mechanical obstructions. Peptic ulcer disease used to be responsible for most gastric outlet obstruction, but in the last 40 years the prevalence of malignant tumors has risen significantly. Adhesive disease is an infrequent and insidious cause of mechanical gastric outlet obstruction. Case presentation We report the case of a 78-year-old Caucasian man who had a clinical history of a right nephrectomy for malignancy three years earlier and who was admitted for a severe gastric outlet obstruction (score of 1 confirmed both by an upper endoscopy and by a fluoroscopic view after contrast injection. A computed tomography scan and a laparotomy, with omental biopsies, showed a peritoneal carcinomatosis with the development of abdominal adhesions that prompted an abnormal gastric rotation around the perpendicular axis of his antrum with a dislocation in the empty space of his right kidney. Symptoms disappeared after surgical bypass through a gastrojejunostomy. Conclusions Our patient experienced a very rare complication characterized by the development of adhesions due to peritoneal carcinomatosis caused by a renal carcinoma treated with nephrectomy. These adhesions prompted an abnormal dislocation of his antrum, as an internal hernia, in the empty space of his right kidney.

    Physiological outflow boundary conditions are necessary to carry out computational fluid dynamics simulations that reliably represent the blood flow through arteries. When dealing with complex three-dimensional trees of small arteries, and therefore with multiple outlets, the robustness and speed of convergence are also important. This study derives physiological outflow boundary conditions for cases in which the physiological values at those outlets are not known (neither in vivo measurements nor literature-based values are available) and in which the tree exhibits symmetry to some extent. The inputs of the methodology are the three-dimensional domain and the flow rate waveform and the systolic and diastolic pressures at the inlet. The derived physiological outflow boundary conditions, which are a physiological pressure waveform for each outlet, are based on the results of a zero-dimensional model simulation. The methodology assumes symmetrical branching and is able to tackle the flow distribution problem when the domain outlets are at branches with a different number of upstream bifurcations. The methodology is applied to a group of patient-specific arteries in the liver. The methodology is considered to be valid because the pulsatile computational fluid dynamics simulation with the inflow flow rate waveform (input of the methodology) and the derived outflow boundary conditions lead to physiological results, that is, the resulting systolic and diastolic pressures at the inlet match the inputs of the methodology, and the flow split is also physiological.

    Full Text Available A hybrid numerical method was used to calculate the flow-induced noise and vibration of the centrifugal pump in the paper. The unsteady flows inside the centrifugal pumps with different blade outlet angles were simulated firstly. The unsteady pressure on the inner surface of the volute and the unsteady force applied on the impeller were analyzed. Then the vibration of the volute and sound field were calculated based on an acoustic-vibro-coupling method. The results show that the pump head has increased 7% while the hydraulic efficiency decreased 11.75% as blade outlet angles increased from 18° to 39°. The amplitude of pressure fluctuation at the first blade passing frequency has decreased but increased at the second-order blade passing frequency as the angle growing. The total fluctuation power near volute tongue goes up about 12% every 3° increment of blade outlet angle. The results also show that vibrating-velocity of the volute at second-order blade passing frequency is much higher than at other frequencies, and the velocity increases rapidly as blade outlet angle varies from 18° to 39°. At the same time, the sound pressure level outside the pump has increased about 8.6 dB when the angle increased from 18° to 39°.

    This study used direct field observations with interior assessments of outlets to validate food store and restaurant data from two commercial business lists conditional on classification of outlet type, including supermarkets, grocery stores, convenience stores, full-service restaurants and fast food restaurants. The study used a stratified random sample that included 274 urban census tracts across 9 counties from the Chicago Metropolitan Statistical Area (MSA) and 46 suburban and 61 rural census tracts across 13 counties from a 50-mile buffer surrounding the MSA. Results showed that agreement between the field observations and the commercial business lists for the food store and restaurant outlets was generally moderate (ranging from fair to good). However, when the listed data were validated based on an exact classification match, agreement was only fair (ranging from poor to moderate) and, in particular, poor for fast food restaurants. The study also found that agreement levels for some outlet types differed by tract characteristics. Commercial databases must be used with caution as substitutes for on the ground data collection.

    2007-05-01

    Alcohol, which is ubiquitous today, is a major health concern. Its use was already relatively high among the youngest respondents, peaked among young adults, and declined in older age groups. Alcohol is causally related to more than 60 different medical conditions. Overall, 4% of the global burden of disease is attributable to alcohol, which accounts for about as much death and disability globally as tobacco and hypertension. Alcohol also promotes the generation of reactive oxygen species (ROS) and/or interferes with the body's normal defense mechanisms against these compounds through numerous processes, particularly in the liver. Photobiomodulation (PBM) is a cell-specific effect of low intensity monochromatic light or low intensity laser irradiation (LIL) on biological systems. The cellular effects of both alcohol and LIL are ligand-independent so that PBM might rehabilitate alcohol induced dysfunction. The PBM on alcohol induced human neutrophil dysfunction and rat chronic atrophic gastritis, the laser acupuncture on alcohol addiction, and intravascular PBM on alcoholic coma of patients and rats have been observed. The endonasal PBM (EPBM) mediated by Yangming channel, autonomic nervous systems and blood cells is suggested to treat alcohol induced dysfunction in terms of EPBM phenomena, the mechanism of alcohol induced dysfunction and our biological information model of PBM. In our opinion, the therapeutic effects of PBM might also be achieved on alcoholic myopathy.

    Zebrafish naturally form social groups called shoals. Previously, we have shown that submerging zebrafish eggs into low concentrations of alcohol (0.00, 0.25, 0.50, 0.75 and 1.00 vol/vol% external bath concentration) during development (24h post-fertilization) for two hours resulted in impaired shoaling response in seven month old young adult zebrafish. Here we investigate whether this embryonic alcohol exposure induced behavioural deficit persists to older age. Zebrafish embryos were exposed either to fresh system water (control) or to 1% alcohol for two hours, 24h after fertilization, and were raised in a high-density tank system. Social behaviour was tested by presenting the experimental fish with a computer animated group of zebrafish images, while automated tracking software measured their behaviour. Control fish were found to respond strongly to animated conspecific images by reducing their distanceand remaining close to the images during image presentation, embryonic alcohol treated fish did not. Our results suggest that the impaired shoaling response of the alcohol exposed fish was not due to altered motor function or visual perception, but likely to a central nervous system alteration affecting social behaviour itself. We found the effects of embryonic alcohol exposure on social behaviour not to diminish with age, a result that demonstrates the deleterious and potentially life-long consequences of exposure to even small amount of alcohol during embryonic development in vertebrates.

    Full Text Available This study explores types of alcohol and surrogates consumed, patterns of consumption, and reasons behind noncommercial alcohol consumption among alcohol-dependent patients in Belarus. The study was conducted in the Belarusian city Grodno in 2012 with 223 alcoholics admitted to narcological clinic using structured interviews. The results suggest that at least 20.2% of alcohol dependent patients regularly consume samogon and 11.8% of patients use surrogates, the most popular among which are medications with a high percentage of ethanol and industrial spirits. The belief that, according to quality criteria, samogon exceeds licensed vodka is the main motive for its consumption. The results of this study suggest the existence of the problem of consumption of noncommercial alcohol among alcohol dependent patients in Belarus.

  4. The risks associated with alcohol use and alcoholism.

    Rehm, Jürgen

    2011-01-01

    Alcohol consumption, particularly heavier drinking, is an important risk factor for many health problems and, thus, is a major contributor to the global burden of disease. In fact, alcohol is a necessary underlying cause for more than 30 conditions and a contributing factor to many more. The most common disease categories that are entirely or partly caused by alcohol consumption include infectious diseases, cancer, diabetes, neuropsychiatric diseases (including alcohol use disorders), cardiovascular disease, liver and pancreas disease, and unintentional and intentional injury. Knowledge of these disease risks has helped in the development of low-risk drinking guidelines. In addition to these disease risks that affect the drinker, alcohol consumption also can affect the health of others and cause social harm both to the drinker and to others, adding to the overall cost associated with alcohol consumption. These findings underscore the need to develop effective prevention efforts to reduce the pain and suffering, and the associated costs, resulting from excessive alcohol use.

    Full Text Available In spite of the great abundance and ecological importance of headwater streams, managers are usually limited by a lack of information about water chemistry in these headwaters. In this study we test whether river outlet chemistry can be used as an additional source of information to improve the prediction of the chemistry of upstream headwaters (size 2, relative to models based on map information alone. Between 2000 and 2008, we conducted 17 synoptic surveys of streams within 9 mesoscale catchments (size 32–235 km2. Over 900 water samples were collected from catchments ranging in size from 0.03 to 235 km2. First we used partial least square regression (PLS to model headwater stream total organic carbon (TOC median and interquartile values for a given catchment, based on a large number of candidate variables including catchment characteristics from GIS, and measured chemistry at the catchment outlet. The best candidate variables from the PLS models were then used in hierarchical linear mixed models (MM to model TOC in individual headwater streams. Three predictor variables were consistently selected for the MM calibration sets: (1 proportion of forested wetlands in the sub-catchment (positively correlated with headwater stream TOC, (2 proportion of lake surface cover in the sub-catchment (negatively correlated with headwater stream TOC, and (3 whole-catchment river outlet TOC (positively correlated with headwater stream TOC. Including river outlet TOC as a predictor in the models gave 5–15% lower prediction errors than using map information alone. Thus, data on water chemistry measured at river outlets offers information which can complement GIS-based modelling of headwater stream chemistry.

    Full Text Available Abstract Background Private outlets are the main suppliers of uncomplicated malaria treatment in Africa. However, they are so numerous that they are difficult for governments to influence and regulate. This study's objective was to evaluate a low-cost outreach education (vendor-to-vendor programme to improve the private sector's compliance with malaria guidelines in Bungoma district, Kenya. The cornerstone of the programme was the district's training of 73 wholesalers who were equipped with customized job aids for distribution to small retailers. Methods Six months after training the wholesalers, the programme was evaluated using mystery shoppers. The shoppers posed as caretakers of sick children needing medication at 252 drug outlets. Afterwards, supervisors assessed the outlets' knowledge, drug stocks, and prices. Results The intervention seems to have had a significant impact on stocking patterns, malaria knowledge and prescribing practices of shops/kiosks, but not consistently on other types of outlets. About 32% of shops receiving job aids prescribed to mystery shoppers the approved first-line drug, sulfadoxine-pyremethamine, as compared to only 3% of the control shops. In the first six months, it is estimated that 500 outlets were reached, at a cost of about $8000. Conclusions Changing private sector knowledge and practices is widely acknowledged to be slow and difficult. The vendor-to-vendor programme seems a feasible district-level strategy for achieving significant improvements in knowledge and practices of shops/kiosks. However, alternate strategies will be needed to influence pharmacies and clinics. Overall, the impact will be only moderate unless national policies and programmes are also introduced.

    Background Many patients with malaria-like symptoms seek treatment in private medicine retail outlets (PMR) that distribute malaria medicines but do not traditionally provide diagnostic services, potentially leading to overtreatment with antimalarial drugs. To achieve universal access to prompt parasite-based diagnosis, many malaria-endemic countries are considering scaling up malaria rapid diagnostic tests (RDTs) in these outlets, an intervention that may require legislative changes and major investments in supporting programs and infrastructures. This review identifies studies that introduced malaria RDTs in PMRs and examines study outcomes and success factors to inform scale up decisions. Methods Published and unpublished studies that introduced malaria RDTs in PMRs were systematically identified and reviewed. Literature published before November 2016 was searched in six electronic databases, and unpublished studies were identified through personal contacts and stakeholder meetings. Outcomes were extracted from publications or provided by principal investigators. Results Six published and six unpublished studies were found. Most studies took place in sub-Saharan Africa and were small-scale pilots of RDT introduction in drug shops or pharmacies. None of the studies assessed large-scale implementation in PMRs. RDT uptake varied widely from 8%-100%. Provision of artemisinin-based combination therapy (ACT) for patients testing positive ranged from 30%-99%, and was more than 85% in five studies. Of those testing negative, provision of antimalarials varied from 2%-83% and was less than 20% in eight studies. Longer provider training, lower RDT retail prices and frequent supervision appeared to have a positive effect on RDT uptake and provider adherence to test results. Performance of RDTs by PMR vendors was generally good, but disposal of medical waste and referral of patients to public facilities were common challenges. Conclusions Expanding services of PMRs to

    intergeneric variability. The variability in the number and orientation of caudal gland outlets among different nematode taxa is discussed. The presence of separate outlets for the caudal glands seems to be widespread within the family Epsilonematidae and has also been observed in various other, unrelated taxa of free-living aquatic nematodes, although their arrangement in Epsilonematidae is opposite. This aberrant arrangement is probably related to the aberrant locomotory pattern in this family.

    Full Text Available A syndrome with urgency, with or without associated urine incontinence and usually accompanied by higher urinary frequency and nocturia has been named “overactive bladder; OAB”. OAB is an entity with complex pathophysiology, involving both myogenic and neurogenic (afferent / efferent bladder innervation disturbances. OAB symptoms accompany benign prostatic hypertrophy - BPH (“obstructive OAB”. The aim of the study was to estimate the autonomic nervous system activity (ANS in the experimental bladder outlet obstruction (BOO which was an animal model of the human BPH. The study was conducted using 30 female rats, divided into two groups: BOO animals (n=15, with surgically induced BOO (by partial ligation of the proximal urethra and control ones (n=15, which underwent sham procedure (without urethral ligation. Two weeks after the surgery, in both groups, ANS activity was estimated using time- and spectral analysis of the heart rate variability recordings. The bladder overactivity in BOO animals was confirmed using urodynamic recordings and bladder histological assessment, juxtaposed against the results of the control group. The key finding of our study was the development of autonomic disturbances in bladder outlet obstruction (BOO rats. Our study revealed that BOO animals were characterised by diminished rMSSD and spectral HRV parameters: TP, LF and HF, in comparison with the control group. The normalised nLF and nHF parameters did not differ significantly in both groups, although slight changes in the nLF (increased and nHF (decreased were noted in BOO group. The absolute VLF value was almost the same in both studied populations, however, the percentage part of this component in the appropriate HRV spectrum differed considerably in both studied groups. In BOO animals, VLF percentage amounted to about 90�20whereas in control animals this parameter reached only about 53�0of the total power spectrum.Thus, to sum up, our findings suggest

    1994-12-15

    The National Institute on Alcohol Abuse and Alcoholism (NIAAA) supports research to elucidate the specific genetic factors, now largely unknown, which underlie susceptibility to alcoholism and its medical complications (including fetal alcohol syndrome). Because of the genetic complexity and heterogeneity of alcoholism, identification of the multiple underlying factors will require the development of new study designs and methods of analysis of data from human families. While techniques of genetic analysis of animal behavioral traits (e.g., targeted gene disruption, quantitative trait locus (QTL) mapping) are more powerful that those applicable to humans (e.g., linkage and allelic association studies), the validation of animal behaviors as models of aspects of human alcoholism has been problematic. Newly developed methods for mapping QTL influencing animal behavioral traits can not only permit analyses of human family data to be directly informed by the results of animal studies, but can also serve as a novel means of validating animal models of aspects of alcoholism. 55 refs.

    2016-01-01

    Social media outlets such as Twitter constitute valuable data sources for understanding human activities in the virtual world from a geographic perspective. This paper examines spatial distribution of tweets and densities within cities. The cities refer to natural cities that are automatically aggregated from a country's small street blocks, so called city blocks. We adopted street blocks (rather than census tracts) as the basic geographic units and topological center (rather than geometric center) in order to assess how tweets and densities vary from the center to the peripheral border. We found that, within a city from the center to the periphery, the tweets first increase and then decrease, while the densities decrease in general. These increases and decreases fluctuate dramatically, and differ significantly from those if census tracts are used as the basic geographic units. We also found that the decrease of densities from the center to the periphery is less significant, and even disappears, if an arbitra...

    2013-05-01

    Full Text Available Background The frequent co-abuse of alcohol and tobacco may suggest that they share some common neurological mechanisms. For example, nicotine acts on Nicotinic acetylcholine receptors (nAChRs in the brain to release dopamine to sustain addiction. Might nAChRs be entwined with alcohol? Objectives This review summarizes recent studies on the relationship between alcohol and nAChRs, including the role of nAChRs in molecular biological studies, genetic studies and pharmacological studies on alcohol, which indicate that nAChRs have been potently modulated by alcohol. Methods We performed a cross-referenced literature search on biological, genetic and pharmacological studies of alcohol and nAChRs. Results Molecular biological and genetic studies indicated that nAChR (genes may be important in mediating alcohol intake, but we still lack substantial evidence about how it works. Pharmacological studies proved the correlation between nAChRs and alcohol intake, and the association between nicotine and alcohol at the nAChRs. The positive findings of varenicline (a partial agonist at the _4_2 nAChR, smoking-cessation pharmaceutical treatment for alcoholism, provides a new insight for treating co-abuse of these two substances. >Conclusions Molecular biological, genetic and pharmacological studies of alcohol at the nAChR level, provide a new sight for preventing and treating the co-abuse of alcohol and nicotine. Given the important role of nAChRs in nicotine dependence, the interaction between alcohol and nAChRs would provide a new insight in finding effective pharmacological treatments, in decreasing or stopping alcohol consumption and cigarette smoking concurrently.

    Despite its low prevalence and incidence, considerable debate exists in the literature on thoracic outlet syndrome (TOS). From literature analysis on nerve entrapments, we realized that TOS is the second most commonly published entrapment syndrome in the literature (after carpal tunnel syndrome) and that it is even more reported than ulnar neuropathy at elbow, which, instead, is very frequent. Despite the large amount of articles, there is still controversy regarding its classification, clinical picture, diagnostic objective findings, diagnostic modalities, therapeutical strategies and outcomes. While some experts believe that TOS is underrated, overlooked and very frequent, others even doubt its existence as a nosological entity. In the attempt to shed more light on this condition, we performed a systematic review of the literature and report evidence and opinions around this controversial subject. Only articles focused on neurogenic TOS were considered. Understanding the status of the art and the underlying reasons of doubts and weaknesses could help clinical practice and set the stage for future research.

  16. Effect of inlet and outlet flow conditions on natural gas parameters in supersonic separation process.

    Directory of Open Access Journals (Sweden)

    Yan Yang

    Full Text Available A supersonic separator has been introduced to remove water vapour from natural gas. The mechanisms of the upstream and downstream influences are not well understood for various flow conditions from the wellhead and the back pipelines. We used a computational model to investigate the effect of the inlet and outlet flow conditions on the supersonic separation process. We found that the shock wave was sensitive to the inlet or back pressure compared to the inlet temperature. The shock position shifted forward with a higher inlet or back pressure. It indicated that an increasing inlet pressure declined the pressure recovery capacity. Furthermore, the shock wave moved out of the diffuser when the ratio of the back pressure to the inlet one was greater than 0.75, in which the state of the low pressure and temperature was destroyed, resulting in the re-evaporation of the condensed liquids. Natural gas would be the subsonic flows in the whole supersonic separator, if the mass flow rate was less than the design value, and it could not reach the low pressure and temperature for the condensation and separation of the water vapor. These results suggested a guidance mechanism for natural gas supersonic separation in various flow conditions.

    Glacier fjord bathymetry and conditions indicate that they play fundamental roles for outlet glacier dynamics and thus knowledge of these parameters is extremely beneficial to upcoming models that predict changes. In particular, the bathymetry of a fjord gives important information about the exchange between fjord waters close to marine-terminating glaciers and the shelf and ocean. Currently, only sparse bathymetric data near the ice fronts are available for the majority of fjords in Greenland. The challenge in obtaining these measurements is that the fjord melange environment is a terrible one for mechanical gear, or ship or any other kind of access. There is hope however, and this work focuses on novel ways of obtaining this data using a multitude of upcoming technologies and techniques that are now being tested and planned. The span of the techniques described include but are not limited to: 1) manned helicopter-based live-reading instruments and deployable/retriavable sensor packages http://www.motionterra.com/fjord/ 2) remote or autonomous unmanned miniature boats (Depth/CTD), and 3) UAV's that either read live data or deploy small sensors that can telemeter their data (ice-flow trackers, image acquisition, etc.). A review of current results obtained at Jakobshavn and Upernavik Glaciers will be given as well as a description of the techniques and hardware used.

    1996-07-01

    The fat, moisture and protein contents of ground beef were determined on-line by a diffuse reflectance near infrared (NIR) spectroscopy instrument at the outlet of a meat grinder. Beef samples in the range of 6.2-21.7% fat, 59.6-72.9% moisture and 18.1-20.7% protein were studied. Calibrations from samples ground with hole diameters of 4, 8, 13 or 19 mm in the grinder plate were validated. In addition, calibrations of combinations of these samples from the different hole diameters were validated. Prediction errors, expressed as root mean square error of cross validation of the beef samples, were 0.73-1.50% for fat, 0.75-1.33% for moisture and 0.23-0.32% for protein, depending on the hole diameter of the grinder plate. Calibrations from samples ground with the smallest hole diameters gave lowest prediction errors. The present prediction error results are only slightly higher compared to reported prediction error results using conventional at- and off-line NIR instruments. It is concluded that the on-line NIR prediction results were acceptable for samples ground with grinder plates of 4, 8 or 13 mm hole diameter.

  19. A MATHEMATICAL MODEL OF THE FLOW FROM THE OUTLET IN DAMS

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    On the basis of the theory of complex functions the authorsderive the boundary integral equations for the flow discharging from an outlet in a dam in an auxiliary plane. Assuming that the integral variables are constants in small integral intervals, one can directly integrate the boundary integral equations. With the use of the boundary stream coordinates, the boundary integral equations in the physical plane are obtained. Therefore the angle of the solid boundaries is a known function of stream coordinates in the physical plane instead of an unknown function in the complex potential plane or auxiliary plane. As a result we avoid the difficulty for seeking the mapping function which conformally maps the physical plane onto the complex potential or auxiliary plane. A synchronous iterative method for the flow rate and the flow pattern is presented. The flow rate, the pressure distributions at the solid walls and the profiles of the free jet are calculated. The numerical results are in excellent agreement with the experimental results.

    Full Text Available Double outlet right ventricle (DORV is a rare congenital heart defect involving the great arteries. In DORV, both aorta and pulmonary artery arise from the right ventricle resulting in admixture of blood. We report a 22-year-old parturient with DORV and severe pulmonary stenosis who underwent caesarean delivery at 36 weeks gestation with low dose combined spinal-epidural anesthesia. This lady was assessed by echocardiogram to have situs inversus, dextrocardia, severe pulmonary artery stenosis (gradient = 146 mm Hg, DORV with subarterial VSD (1 cm. She had 95% room air saturation and her blood investigations were within normal limits. We established a peripheral venous access and radial arterial line for continuous blood pressure monitoring. Combined spinal epidural anesthesia was considered a better option. Epidural catheter was secured at L 2 -L 3 space and fixed after giving test dose 3 mL 2% lignocaine. Subarachnoid block administered at L 3 -L 4 level using 1.2 mL of 0.5% heavy bupivacaine. A sensory block of T 10 was obtained which was supplemented with 4 mL 0.75% ropivacaine to obtain a level of T 6 . Patient tolerated the procedure well. She was shifted to post-operative ICU. Post-operative pain was managed with epidural 0.2% ropivacaine at 4 mL/h. Patient remained hemodynamically stable throughout the procedure and in the postoperative period while she was being followed up for subsequent 48 h.

    The mass balance of the Greenland ice sheet (GrIS) is, in part, governed by the dynamics of ocean-terminating glaciers. GRACE data reveal that along the central-west coast of the GrIS, overall ice loss has been accelerating since 2007. However, we do not know the physical processes controlling the loss here, and the changes observed are not uniform in this region; several glaciers have gone through periods of slow-down in the recent past. To address these uncertainties, we have performed ~30-year DEM differences of outlet glaciers in the region. Present-day DEMs have been created from WorldView-1 and -2 (WV) stereo imagery acquired in 2012 and 2013 using the AMES Stereo Pipeline. A 1985 DEM was created from a Greenland aerial photo survey. The DEM differences between the present-day WV DEMs and the 1985 aerial photo DEM show clearly that spatial variability in the surface elevation and terminus position changes of the glaciers in the region has been ongoing for the last ~30 years. We examine this variability in the context of ocean temperature and surface mass balance estimates to yield further insight into the external controls on these glaciers.

    This paper presents a stationary and dynamic study of the advantages of using a regulating valve for the cathode outlet flow in combination with the compressor motor voltage as manipulated variables in a fuel cell system. At a given load current, the cathode input and output flow rate determine the cathode pressure and stoichiometry, and consequently determine the oxygen partial pressure, the generated voltage and the compressor power consumption. In order to maintain a high efficiency during operation, the cathode output regulating valve has to be adjusted to the operating conditions, specially marked by the current drawn from the stack. Besides, the appropriate valve manipulation produces an improvement in the transient response of the system. The influence of this input variable is exploited by implementing a predictive control strategy based on dynamic matrix control (DMC), using the compressor voltage and the cathode output regulating valve as manipulated variables. The objectives of this control strategy are to regulate both the fuel cell voltage and oxygen excess ratio in the cathode, and thus, to improve the system performance. All the simulation results have been obtained using the MATLAB-Simulink environment. (author)

    Full Text Available Abstract Objective Thoracic outlet syndrome (TOS is a clinical phenomenon resulting from compression of the neurovascular structures at the superior aperture of the thorax which presents with varying symptoms. Regarding to the varying symptoms, the diagnosis of TOS seems to be a challenge and predictors for the outcome are rare. The purpose of this study was therefore to analyze the different clinical examinations and tests relative to their prediction of the clinical outcome subsequent to surgery. Methods During a period of five years, 56 patients were diagnosed with TOS. Medical history, clinical tests, operative procedure and complications were recorded and analysed. Mean follow-up of the patients was 55.6 ± 45.5 months, median age of the patients was 36.4 ± 12.5 years. Results Different clinical tests for TOS showed an acceptable sensitivity overall, but a poor specificity. A positive test was not associated with a poor outcome. Analyses of the systolic blood pressure before and after exercise showed, that a distinct decrease in blood pressure of the affected side after exercises was associated with a poor outcome (p = 0.0027. Conclusions Clinical tests for TOS show a good sensitivity, but a poor specificity and cannot be used as predictors for the outcome. A distinct decrease in blood pressure of the affected side after exercises was associated with poor outcome and might be useful to predict the patients' outcome.

    Campylobacter was detected in 76% of broiler meat products collected in retail outlets during a monitoring plan carried out in France throughout 2009. Campylobacter jejuni was the most prevalent species (64.7% of products being contaminated). The 175 C. jejuni isolates collected were characterized. MLST typing results confirmed substantial genetic diversity as the 175 C. jejuni isolates generated 76 sequence types (STs). The ST-21, ST-45 and ST-464 complexes predominated accounting for 43% of all isolates. A class-specific PCR to screen the sialylated lipooligosaccharide (LOS) locus classes A, B and C showed that 50.3% of the C. jejuni isolates harbored sialylated LOS. The antimicrobial resistance profiles established using a subset of 97 isolates showed that resistance to tetracycline was the most common (53.6%), followed with ciprofloxacin and nalidixic acid (32.9%, and 32.0% respectively). All the tested isolates were susceptible to erythromycin, chloramphenicol and gentamicin. Clear associations were demonstrated between certain clonal complexes and LOS locus classes and between certain clonal complexes and antimicrobial resistance. This work paints a representative picture of C. jejuni isolated from poultry products circulating in France, providing data on STs, LOS locus classes and antibiotic resistance profiles in isolates recovered from products directly available to the consumer.

  5. Perforated mechanism of a water line outlet tee pipe for an oil well drilling rig

    Full Text Available A corroded tee pipe belonging to a 10-in new separator water line outlet installed in an offshore oil well drilling rig was investigated. The configuration of the large corroded pit had the shape of an imperfect horse's hoof with a completely corroded interior and a honeycomb-like cavity. There is a badly corroded pit at the welded seam at the joint connecting the tee pipe and flange. The material strength of the tee pipe meets the requirement of ASTM-A234 Gr. WPR, but its chemical composition does not meet the stipulated requirements. A deformed streamline structure or twin crystal in the ferrite phase can be seen near the surface or sub-surface of the perforated corrosion puncture edge. The micro-hardness is also different from that of the original material. The SEM results show that the puncture appears to have been a mode of quasi-cleavage fractures with secondary cracks along the direction of the crystal grain; thus, the failure has the features of mechanical and chemical corrosion. The corroded surface contains high amounts of O, C, and N, as well as S, Cl, Si, Na, Mg, Al, K, Ti, etc., all of which are corrosion products caused by sea water. The penetrating puncture hole at the turn of the tee pipe is likely the result of cavitation erosion accompanied by chemical/electrochemical corrosion, and the corrosion on the seam connecting the tee pipe and flange is likely the result of electrochemical corrosion.

    There are currently many disease-specific groups on Facebook in which patients may take an active part (Greene, Choudhry, Kilabuk, & Shrank, 2011). Although uses and gratifications of patient-disease groups have begun to be identified for chronic diseases, rare diseases have been omitted, even though they collectively affect roughly 30 million people in the United States and 350 million people worldwide. This study is a content analysis of one Facebook rare disease patient group, the Thoracic Outlet Syndrome (TOS) Awareness group. All wall posts were recorded and content analyzed for cognitive and affective categories and subcategories between October 9, 2011 (date of site origin), and May 1, 2012. Analysis of cognitive needs indicated TOS patients used the site more to share information about their own TOS symptoms and journey with diagnosis than to seek information. Analysis of affective needs found patients were more likely to use the site to give support and encouragement to others than to express concerns and complaints. The complaints they did express were primarily related to their frustration with the general medical community's perceived inability to diagnose and understand their disease or to question a specific doctor's diagnosis/recommendation. Results point to needs specific to TOS patients that uses and gratifications research can help clarify.

    This study provides information on juvenile salmonid behaviors at McNary and The Dalles dams that can be used by the USACE, fisheries resource managers, and others to support decisions on long-term measures to enhance fish passage. We researched smolt movements and ambient hydrodynamic conditions using a new approach combining simultaneous acoustic Doppler current profiler (ADCP) and acoustic imaging device (AID) measurements at surface flow outlets (SFO) at McNary and The Dalles dams on the Columbia River during spring and summer 2007. Because swimming effort vectors could be computed from the simultaneous fish and flow data, fish behavior could be categorized as passive, swimming against the flow (positively rheotactic), and swimming with the flow (negatively rheotactic). We present bivariate relationships to provide insight into fish responses to particular hydraulic variables that engineers might consider during SFO design. The data indicate potential for this empirical approach of simultaneous water/fish measurements to lead to SFO design guidelines in the future.

    2016-01-01

    Malignant gastric outlet obstruction (GOO) is a commoncondition that results from locally advanced malignanciesin the upper gastrointestinal tract, such aspancreatic, gastric, and other carcinomas. Two typesof procedures for malignant GOO, namely, gastrojejunostomy(GJ) with laparotomy or a laparoscopicapproach and endoscopic stenting (ES), are currentlyavailable. Although numerous previous reports haveclarified the benefits and drawbacks of each procedure,whether GJ or ES should be used in patients with GOOthat results from gastric cancer who may have a longerlife expectancy than patients with other malignancieshas not been determined. In this review, which focuseson gastric cancer-induced GOO, we analyzed the twosystematic reviews and a meta-analysis that comparedGJ and ES and outlined the current status of GOOtreatment. We also provide an updated review thatincludes laparoscopic GJ. Various data from 13 studiesin one review and 6 studies in another review wereanalyzed. Although the main results of the presentreview indicated that both GJ and ES were efficacioustreatments in patients with GOO that resulted fromgastric cancer, current evidence suggests that GJ maybe the preferable procedure given its good performancestatus and improved prognosis in gastric cancer patients.

    2013-09-01

    Full Text Available An adaptive neuro-fuzzy inference system (ANFIS was developed using the subtractive clustering technique to study the air demand in low-level outlet works. The ANFIS model was employed to calculate vent air discharge in different gate openings for an embankment dam. A hybrid learning algorithm obtained from combining back-propagation and least square estimate was adopted to identify linear and non-linear parameters in the ANFIS model. Empirical relationships based on the experimental information obtained from physical models were applied to 108 experimental data points to obtain more reliable evaluations. The feed-forward Levenberg-Marquardt neural network (LMNN and multiple linear regression (MLR models were also built using the same data to compare model performances with each other. The results indicated that the fuzzy rule-based model performed better than the LMNN and MLR models, in terms of the simulation performance criteria established, as the root mean square error, the Nash–Sutcliffe efficiency, the correlation coefficient and the Bias.

    Occupational specialists are well aware of the lack of objective measurements for the diagnosis and the functional evaluation of workers affected by thoracic outlet syndrome (TOS). Subjects affected by TOS refer pain, sensation of fatigue in the arm frequently aggravated by overhead work. A "stick-up" position tends to close the costoclavicular space and tense the neck and shoulder muscles to bring into play the abnormal compression mechanism that may affect the brachial plexus nerves and the subclavian vessels. In a previous study, we demonstrated the reliability of an isokinetic hand grip endurance test. In this pilot study we asked 7 industrial workers affected by TOS to perform a 30-second isokinetic endurance test for hand gripping with a Lido WorkSET dynamometer. Tests were performed in two positions (resting and "stick-up" position) before and after a 3-week intensive rehabilitation program. In addition, the subjects performed daily aerobic exercise with an arm crank ergometer. Objective indexes of posttreatment improvement were found. Subjects were able to generate higher grip forces during the isokinetic hand grip endurance test and to sustain higher mechanical workload with the arm ergometer at the same intensity level for longer duration after completion of the rehabilitation program.

    2006-12-01

    Full Text Available We examined the involvement of the signal transducer and activator of transcription 3 (STAT3 in bladder outlet obstruction (BOO-induced bladder smooth muscle hypertrophy using a rat in vivo and in vitro study. BOO induced increases in bladder weight and bladder smooth muscle thickness 1 week after the operation. By using antibody microarrays, 64 of 389 proteins blotted on the array met our selection criteria of an INR value between > or = 2.0 and < or = 0.5. This result revealed up-regulation of transcription factors, cell cycle regulatory proteins, apoptosis-associated proteins and so on. On the other hand, down-regulation (INR value < or = 0.5 of proteins was not found. In a profiling study, we found an increase in the expression of STAT3. A significant increase in nuclear phosphorylated STAT3 expression was confirmed in bladder smooth muscle tissue by immunohistochemistry and Western blot analysis. Cyclical stretch-relaxation (1 Hz at 120% elongation significantly increased the expression of STAT3 and of alpha-smooth muscle actin in primary cultured bladder smooth muscle cells. Furthermore, the blockade of STAT3 expression by the transfection of STAT3 small interfering RNA (siRNA significantly prevented the stretch-induced increase in alpha-smooth muscle actin expression. These results suggest that STAT3 has an important role in the induction of bladder smooth muscle hypertrophy.

    To study the dynamics of Breath Figure phenomenon, a control of both the rate of flow and temperature of water vapor is required. The experimental setup widely used is a non hermetically closed chamber with cylindrical geometry and axial inlets and outlets. In this work we present measurements in a cylindrical chamber with diameter 10 cm and 1.5 cm height, keeping a constant temperature (10 °C). We are focused in the velocity field when a gradient of the temperatures is produced between the base plate and the vapor. With a flux of water vapor of 250 mil/min at room temperature (21 °C), the Reynolds number measured in one inlet is 755. Otherwise, the temperatures of water vapor varies from 21 to 40 °C. The velocity profile is obtained by hot wire anemometry. We identify the stagnations and the possibly instabilities regions for an empty plate and with a well defined shape obstacle as a fashion sample. Facultad de Ciencias, UNAM.

    Background Non-alcoholic steatohepatitis (NASH) is a serious form of non-alcoholic fatty liver disease (NAFLD), associated with obesity and insulin resistance. Previous studies suggested that intestinal bacteria produced more alcohol in obese mice than lean animals. Methodology/Principal Findings To investigate whether alcohol is involved in the pathogenesis of NASH, the expression of inflammation, fibrosis and alcohol metabolism related genes in the liver tissues of NASH patients and normal controls (NCs) were examined by microarray (NASH, n = 7; NC, n = 4) and quantitative real-time PCR (NASH, n = 6; NC, n = 6). Genes related to liver inflammation and fibrosis were found to be elevated in NASH livers compared to normal livers. The most striking finding is the increased gene transcription of alcohol dehydrogenase (ADH) genes, genes for catalase and cytochrome P450 2E1, and aldehyde dehydrogenase genes. Immunoblot analysis confirmed the increased expression of ADH1 and ADH4 in NASH livers (NASH, n = 9; NC, n = 4). Conclusions/Significance The augmented activity of all the available genes of the pathways for alcohol catabolism suggest that 1) alcohol concentration was elevated in the circulation of NASH patients; 2) there was a high priority for the NASH livers to scavenge alcohol from the circulation. Our data is the first human evidence that suggests alcohol may contribute to the development of NAFLD. PMID:20221393

    The CERN Medical Service has observed an increase in the number of personnel suffering from alcohol-related problems in recent years, in spite of the implementation of stricter regulations concerning the consumption of alcohol on the site. The causes of alcohol-related problems are often complex and many-faceted. A family history of alcohol abuse can be a cofactor in excessive drinking. The effects on a person's work are not negligible and should not be ignored. "Alcohol and the work place" is the third part of a campaign designed to raise awareness of the risks of alcohol consumption, which has already dealt with "alcohol and health" and "alcohol and road safety".Many employers have taken steps to confront the problem, and CERN launched a campaign to help its employees suffering from alcohol-related problems over ten years ago. A standing SCC sub-group on the prevention of alcoholism has been set up and Operational Circular No. 8, which defines the role and responsibilities of all parties concerned in the m...

    Full Text Available Abstract Background Availability is an important predictor of early and excessive alcohol consumption by adolescents. Many countries have implemented age limits to prevent underage purchases of alcohol. However, shop-floor compliance with these age limits appears to be problematic. This study addresses the issue of non-compliance with age limits. Which measures do vendors take to avoid underage alcohol sales, and what do they report as important reasons to comply or not with age limits for alcohol sales? Methods Open-ended telephone interviews were conducted with store managers selling alcohol (N = 106. Prior to the interviews, all outlets were visited by an underage mystery shopper in order to measure compliance with the legal age limits on alcohol sales. The interview results are compared against actual compliance rates. Results Several measures have been taken to prevent underage sales, but the compliance level is low. Furthermore, open coding resulted in 19 themes, representing both valid and invalid arguments, that vendors mentioned as relevant to their decisions of whether to comply with the law. Compliance with age limits is dependent on the knowledge of the rules and the ability and motivation to follow the rules. The ability aspect in particular seems to be problematic, but in many cases, the motivation to actively comply with the age limits is lacking. Conclusions To enhance compliance, it is important to raise the awareness of the importance of age limits and to connect possible violations of the regulations to negative consequences.

  4. Principles and Materials Aspects of Direct Alkaline Alcohol Fuel Cells

    2010-08-01

    Full Text Available Direct alkaline alcohol fuel cells (DAAFCs have attracted increasing interest over the past decade because of their favourable reaction kinetics in alkaline media, higher energy densities achievable and the easy handling of the liquid fuels. In this review, principles and mechanisms of DAAFCs in alcohol oxidation and oxygen reduction are discussed. Despite the high energy densities available during the oxidation of polycarbon alcohols they are difficult to oxidise. Apart from methanol, the complete oxidation of other polycarbon alcohols to CO2 has not been achieved with current catalysts. Different types of catalysts, from conventional precious metal catalyst of Pt and Pt alloys to other lower cost Pd, Au and Ag metal catalysts are compared. Non precious metal catalysts, and lanthanum, strontium oxides and perovskite-type oxides are also discussed. Membranes like the ones used as polymer electrolytes and developed for DAAFCs are reviewed. Unlike conventional proton exchange membrane fuel cells, anion exchange membranes are used in present DAAFCs. Fuel cell performance with DAAFCs using different alcohols, catalysts and membranes, as well as operating parameters are summarised. In order to improve the power output of the DAAFCs, further developments in catalysts, membrane materials and fuel cell systems are essential.

    2016-03-01

    © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. We developed a single-enzyme-mediated two-step approach for deracemization of secondary alcohols. A single mutant of Thermoanaerobacter ethanolicus secondary alcohol dehydrogenase enables the nonstereoselective oxidation of racemic alcohols to ketones, followed by a stereoselective reduction process. Varying the amounts of acetone and 2-propanol cosubstrates controls the stereoselectivities of the consecutive oxidation and reduction reactions, respectively. We used one enzyme to accomplish the deracemization of secondary alcohols with up to >99% ee and >99.5% recovery in one pot and without the need to isolate the prochiral ketone intermediate.

    2014-01-01

    Full Text Available Alcohol abuse and alcoholism are the leading causes of worse health and increased mortality rates. Excessive alcohol consumption is the third leading cause of the global burden of diseases and a leading factor for lower lifespan and higher mortality. Alcohol abuse decreases working capacity and efficiency and requires the increased cost of the treatment of alcohol-induced disorders, which entails serious economic losses. The unfavorable medical and social consequences of excessive alcohol use determine the importance of effective treatment for alcoholism. The goals of rational pharmacotherapy of alcohol dependence are to enhance GABA neurotransmission, to suppress glutamate neurotransmission, to act on serotonin neurotransmission, to correct water-electrolyte balance, and to compensate for thiamine deficiency. Alcoholism treatment consists of two steps: 1 the prevention and treatment of alcohol withdrawal syndrome and its complications (withdrawal convulsions and delirium alcoholicum; 2 antirecurrent (maintenance therapy. Benzodiazepines are the drugs of choice in alleviating alcohol withdrawal and preventing its convulsive attacks and delirium alcoholicum. Diazepam and chlordiazepoxide are most commonly used for this purpose; the safer drugs oxazepam and lorazepam are given to the elderly and patients with severe liver lesions. Anticonvulsants having normothymic properties, such as carbamazepine, valproic acid, topiramate, and lamotrigine, are a definite alternative to benzodiazepines. The traditional Russian clinical practice (clearance detoxification has not a scientific base or significant impact on alcohol withdrawal-related states in addicts. Relapse prevention and maintenance therapy for alcohol dependence are performed using disulfiram, acamprosate, and naltrexone; since 2013 the European Union member countries have been using, besides these agents, nalmefene that is being registered in Russia.

    Full Text Available Purpose We aimed to compare the associations between semen quality, associated reproductive indicators and the main prostate-related parameters in middle-aged men. Materials and Methods: This is a prospective study on 422 middle-aged men who underwent the screening for prostate health. Their reproductive function, semen quality and prostate-related pathologies were investigated. Results Significant associations between semen quality and prostate-related parameters could be seen. Total sperm count and sperm density decreased along with the increase of the I-PSS score and total prostate volume. Also, the related lower urinary tract characteristics showed a negative correlation with main semen parameters for all investigated subjects. No significant differences in age, testicular size, and hormonal parameters were found between the subjects with or without lower urinary tract symptoms and prostate enlargement. Conclusions Our study suggests that altered seminal parameters in middle-aged men are associated with LUTS, prostate enlargement and/or bladder outlet obstruction. Although the assessments of prostate and lower urinary tract symptoms may not replace the semen parameters evaluating the male reproductive status, there is a need for further and more detailed investigations about the pathways behind these associations as well as possible related conditions.

    Both pathological and neuroimaging studies demonstrate that chronic alcohol abuse causes brain atrophy with widespread white matter loss limited gray matter loss. Recent neuroimaging studies suggest that tobacco smoking also causes brain atrophy in both alcoholics and neurologically normal individuals; however, this has not been confirmed pathologically. In this study, the effects of smoking and the potential additive effects of concomitant alcohol and tobacco consumption were investigated in autopsied human brains. A total of 44 cases and controls were divided into four groups: 16 non-smoking controls, nine smoking controls, eight non-smoking alcoholics, and 11 smoking alcoholics. The volumes of 26 gray and white matter regions were measured using an established point-counting technique. The results showed trends for widespread white matter loss in alcoholics (p smoking alone had no effect on brain atrophy and the combination of smoking and alcohol showed no additional effect. Neuronal density was analyzed as a more sensitive assay of gray matter integrity. Similar to the volumetric analysis, there was a reduction in neurons (29%) in the prefrontal cortex of alcoholics, albeit this was only a trend when adjusted for potential confounders (p smoking or combinatorial effects on neuronal density in any of the three regions examined. These results do not support the hypothesis that smoking exacerbates alcohol-related brain damage. The trends here support previous studies that alcohol-related brain damage is characterized by focal neuronal loss and generalized white matter atrophy. These disparate effects suggest that two different pathogenic mechanisms may be operating in the alcoholic brain. Future studies using ultrastructural or molecular techniques will be required to determine if smoking has more subtle effects on the brain and how chronic alcohol consumption leads to widespread white matter loss.

    AIM: To examine the relations of alcohol consumption to the prevalence of metabolic syndrome in Shanghai adults.METHODS: We performed a cross-sectional analysis of data from the randomized multistage stratified cluster sampling of Shanghai adults, who were evaluated for alcohol consumption and each component of metabolic syndrome, using the adapted U.S. National Cholesterol Education Program criteria. Current alcohol consumption was defined as more than once of alcohol drinking per month.RESULTS: The study population consisted of 3953participants (1524 men) with a mean age of 54.3 ± 12.1years. Among them, 448 subjects (11.3%) were current alcohol drinkers, including 405 males and 43 females.After adjustment for age and sex, the prevalence of current alcohol drinking and metabolic syndrome in the general population of Shanghai was 13.0% and 15.3%,respectively. Compared with nondrinkers, the prevalence of hypertriglyceridemia and hypertension was higher while the prevalence of abdominal obesity, low serum high-density-lipoprotein cholesterol (HDL-C) and diabetes mellitus was lower in subjects who consumed alcohol twice or more per month, with a trend toward reducing the prevalence of metabolic syndrome. Among the current alcohol drinkers, systolic blood pressure, HDL-C, fasting plasma glucose, and prevalence of hypertriglyceridemia tended to increase with increased alcohol consumption.However, Iow-density-lipoprotein cholesterol concentration,prevalence of abdominal obesity, low serum HDL-C andmetabolic syndrome showed the tendency to decrease.Moreover, these statistically significant differences were independent of gender and age.CONCLUSION: Current alcohol consumption is associatedwith a lower prevalence of metabolic syndrome irrespe-ctive of alcohol intake (g/d), and has a favorable influence on HDL-C, waist circumference, and possible diabetes mellitus. However, alcohol intake increases the likelihoodof hypertension, hypertriglyceridemia and hyperglycemia

    The quality of river water or other surface waters is detrimentally affected by the contaminants carried by the rainfall runoff in urban areas. The control of pollution moved by rainfall runoff is achieved by installing outlets and small retention basins in stormwater collection systems, thereby allowing only a certain amount of rainfall water to overflow and leading the remaining to treatment plants. This study analyses the effect of concentration time on surface water pollution caused by rainfall runoff. For this purpose, a linear -curve is assumed for the flow hydrograph arising from the collection system, based on parameters of rainfall considered and the catchment area. An independent code is developed to analyse such a system and this is applied to an urban area using nine-year single-discrete rainfall records of Izmir Station, Turkey. The system is capable of tackling situations where there is only a basin or a basin with outlet.

    An optical technique has been developed for the measurement of the eddy diffusivity of heat in a transparent flowing medium. The method uses a combination of two established measurement tools: a Mach--Zehnder interferometer for the monitoring of turbulently fluctuating temperature and a Laser Doppler Anemometer (LDA) for the measurement of turbulent velocity fluctuations. The technique is applied to the investigation of flow fields characteristic of the LMFBR outlet plenum. The study is accomplished using air as the working fluid in a small scale Plexiglas test section. Flows are introduced into both the 1/15 scale FFTF outlet plenum and the 3/80 scale CRBR geometry plenum at inlet Reynolds numbers of 22,000.

    The melting of tidewater outlet glaciers from the Greenland Ice Sheet contributes significantly to global sea level rise. Accelerated mass loss is related to melt-processes in front of calving glaciers, yet the role of ocean heat transports is poorly understood. Here we present the first direct...... measurements from a subglacial plume in front of a calving tidewater outlet glacier. Surface salinity in the plume corresponded to a meltwater content of 7 %, which is indicative of significant entrainment of warm bottom water and, according to plume model calculations, significant ice melt. Energy balance...... of the area near the glacier showed that ice melt was mainly due to ocean heat transport and that direct plume-associated melt was only important in periods with high meltwater discharge rates of ~100 m3 s−1. Ocean mixing outside of the plume area was thus the primary heat source for melting glacier ice....

    Alcoholism is a complex psychiatric disorder that has a multifactorial etiology. Epigenetic mechanisms are uniquely capable of accounting for the multifactorial nature of the disease in that they are highly stable and are affected by environmental factors, including alcohol itself. Chromatin remodeling causes changes in gene expression in specific brain regions contributing to the endophenotypes of alcoholism such as tolerance and dependence. The epigenetic mechanisms that regulate changes in gene expression observed in addictive behaviors respond not only to alcohol exposure but also to comorbid psychopathology such as the presence of anxiety and stress. This review summarizes recent developments in epigenetic research that may play a role in alcoholism. We propose that pharmacologically manipulating epigenetic targets, as demonstrated in various preclinical models, hold great therapeutic potential in the treatment and prevention of alcoholism.

    Prepared at the request of US Senator Birch Bayh, Chairman of the National Alcohol Fuels Commission, this study may be best utilized as a guidebook and resource manual to foster the development of a statewide fuel alcohol plan. It examines sectors in Indiana which will impact or be impacted upon by the fuel alcohol industry. The study describes fuel alcohol technologies that could be pertinent to Indiana and also looks closely at how such a fuel alcohol industry may affect the economic and policy development of the State. Finally, the study presents options for Indiana, taking into account the national context of the developing fuel alcohol industry which, unlike many others, will be highly decentralized and more under the control of the lifeblood of our society - the agricultural community.

  15. Ice-ocean interaction and calving front morphology at two west Greenland tidewater outlet glaciers

    Warm, subtropical-originating Atlantic water (AW) has been identified as a primary driver of mass loss across the marine sectors of the Greenland Ice Sheet (GrIS), yet the specific processes by which this water mass interacts with and erodes the calving front of tidewater glaciers is frequently modelled and much speculated upon but remains largely unobserved. We present a suite of fjord salinity, temperature, turbidity versus depth casts along with glacial runoff estimation from Rink and Store glaciers, two major marine outlets draining the western sector of the GrIS during 2009 and 2010. We characterise the main water bodies present and interpret their interaction with their respective calving fronts. We identify two distinct processes of ice-ocean interaction which have distinct spatial and temporal footprints: (1) homogenous free convective melting which occurs across the calving front where AW is in direct contact with the ice mass, and (2) localised upwelling-driven melt by turbulent subglacial runoff mixing with fjord water which occurs at distinct injection points across the calving front. Throughout the study, AW at 2.8 ± 0.2 °C was consistently observed in contact with both glaciers below 450 m depth, yielding homogenous, free convective submarine melting up to ~200 m depth. Above this bottom layer, multiple interactions are identified, primarily controlled by the rate of subglacial fresh-water discharge which results in localised and discrete upwelling plumes. In the record melt year of 2010, the Store Glacier calving face was dominated by these runoff-driven plumes which led to a highly crenulated frontal geometry characterised by large embayments at the subglacial portals separated by headlands which are dominated by calving. Rink Glacier, which is significantly deeper than Store has a larger proportion of its submerged calving face exposed to AW, which results in a uniform, relatively flat overall frontal geometry.

    Background: Gastric outlet obstruction (GOO) can occur with locally invasive or metastatic cancer involving the upper gastrointestinal tract at the pylorus or the duodenum. Endoscopic management with self-expanding metal stents (SEMSs) is often the preferred palliative approach. Stent occlusion is a common reason for failure and reintervention. We set out to determine whether the location of the malignant obstruction is associated with the angulation of the stent and can predict stent occlusion. Methods: We performed a retrospective review of consecutive patients who underwent successful duodenal stenting with SEMS for malignant GOO between 2006 and 2015 at a large advanced endoscopy referral center. We determined the location of obstruction, the stent angle, and the rate of technical and clinical success of stent placement. We then identified cases of subsequent stent occlusion confirmed by endoscopic evaluation. Results: A total of 100 consecutive patients were included in the study; 91 of these patients had enough data to evaluate SEMS occlusion. A total of 21 patients (23%) developed stent occlusion with a median time of 39 days. The risk of occlusion sequentially increased as the obstruction occurred more distally from the antrum to the third or fourth portion of the duodenum (p = 0.006). This relationship was maintained after controlling for stent angle (p = 0.05). Conclusions: A distal location of malignant GOO was strongly predictive of stent occlusion, independent of stent angle. This may be due to longer and more complex distal obstructions, along with foreshortening of the stent during placement and tumor infiltration. If replicated, these results will have implications for endoscopic practice and future device development. PMID:27803736

    This paper gives a special focus on the role of outlet temperature of flue gas (T{sub go}) in organic Rankine cycle (ORC) system for low temperature flue gas waste heat recovery. The variations of performance indicators: net work (W{sub net}), exergy efficiency (η{sub ex}) and levelized energy cost (LEC) versus T{sub go} are discussed. Considering the corrosion of low temperature flue gas, the necessity and reasonability of limiting T{sub go} at its minimum allowed discharge temperature (355.15 K) are analyzed. Results show that there exist optimal T{sub go} (T{sub go,opt}) for W{sub net} and LEC, while T{sub go,opt} for η{sub ex} does not appear under the investigated range of T{sub go}. Moreover, the T{sub go,opt} for W{sub net} is always lower than 355.15 K, the T{sub go,opt} for LEC, despite being greater than the one for W{sub net}, is just slightly higher than 355.15 K when the inlet temperature of flue gas varies from 408.15 K to 463.15 K. For the waste heat recovery of low temperature flue gas, it is reasonable to fix T{sub go} at 355.15K if W{sub net} or LEC is selected as primary performance indicator under the pinch point temperature difference of evaporator (ΔT{sub e}) below 20K.

    Full Text Available Objective: To compare pressure-flow study on one hand with BWT, prostate volume, urine flow rate PVR and IPSS index in the other arm for diagnosis of BOO. Materials and methods: A prospective cross-sectional study was carried out in 48 men with lower urinary tract symptoms (LUTS. International prostate symptom score was completed by the patient who then underwent free urine flow study. Pressure-Flow study was performed as per recommendations of International continence Society. Abrams-Griffiths nomogram and number were used to diagnose BOO. Patients with diabetes, neurovesical dysfunction, acute urinary retention, prior pelvic surgery and known prostate cancer were excluded. Suprapubic ultrasonography was performed independently by a consultant radiologist, who was blinded to findings of Pressure-Flow study. Prevoid bladder volume, postvoid residue (PVR, prostate volume and bladder wall thickness (BWT were noted. Results: Based on objective evidence from Pressure-Flow study, 35 patients were obstructed, 13 were not. Multivariate analysis was performed using Backward Stepwise Logistic Regression Model. Bladder wall thickness, prostate volume and urine flow rate had statistically significant relationship with BOO. Their coefficients of correlation were +0.794, +0.084 and 0.393 respectively. Bladder outlet obstruction could be defined by using a mathematical formula as detailed in the text (Positive Predictive Value 96.97%. Post-void residue and IPSS index were statistically insignificant. Conclusion: In a select group of patients presenting with LUTS, it should be possible to diagnose BOO without the use of Pressure-Flow study.

    2006-07-01

    The physicochemical, microbiological, and organoleptic profile of different commercial table olive products from retail outlets was studied. Average pH values were 4.00, 3.96, and 4.31 for Spanish-style green, naturally black, and dry-salted olives, respectively, while salt content was 6.21, 7.34, and 8.00% for the same commercial products. Mean values for titratable acidity were 0.53 and 0.63% (wt/vol) for green and naturally black olives. In general, mean values for pH, titratable acidity, and salt content were in accordance with the requirements established by the International Olive Oil Council (IOOC) for the trade of table olives, although considerable variation was observed within individual olive samples. Salt content of dry-salted olives did not meet the minimum limit of 10% established by the IOOC. The dominant microbiota consisted of lactic acid bacteria and yeasts. Their population was less than 10(9) CFU ml(-1), as stipulated by the IOOC standard for fermented olives held in bulk in a covering liquid. These microorganisms come from the natural microbiota found in spontaneous fermentations and impose no risk to human health. No enterobacteria, pseudomonads, Bacillus cereus, or Clostridium perfringens were detected in any of the samples given the physicochemical characteristics found. The organoleptic profile varied greatly according to processing style and commercial preparation. Green olives had more uniform sensory characteristics than naturally black and dry-salted olives. The most important attributes that influenced the judgment of the panelists were salt content and crispness of the olives.

  20. Intussuscepting Ampullary Adenoma: An Unusual Cause of Gastric Outlet Obstruction Leading to Cavitating Lung Lesions

    Simon J. McCluney

    2016-10-01

    Full Text Available Ampullary adenomas are a rare clinical entity, occurring at a rate of 0.04–0.12% in the general population. They are premalignant lesions which have the capability to progress to malignancy, and they should be excised if they are causing immediate symptoms and/or are likely to degenerate to carcinoma. Intestinal intussusception in adults is rare and, unlike in children, is often due to a structural pathology. Intussuscepting duodenal/ampullary adenomas have been reported in the literature on 13 previous occasions, however never before with this presentation. We report the case of a woman who presented with a 1-year history of recurrent chest infections. She was treated with numerous antibiotics, whilst intermittent symptoms of recurrent vomiting and weight loss were initially attributed to her lung infections. A chest CT demonstrated multiple cavitating lung lesions, whilst an obstructing polypoid mass was noted at D2 on dedicated abdominal imaging. Due to ongoing nutritional problems, she had a semi-urgent pancreaticoduodenectomy. Intraoperative findings demonstrated a large mass at D2 with a duodeno-duodenal intussusception. Histological analysis reported a duodenal, ampullary, low-grade tubular adenoma, 75 × 28 × 30 mm in size, with intussusception and complete resection margins. The patient recovered well and was discharged on postoperative day 10, with no complications to date. Ampullary adenomas may present with obstruction of the main gastrointestinal tract and/or biliary/pancreatic ducts. Common presentations include gastric outlet obstruction, gastrointestinal bleeding or acute pancreatitis. This unique presentation should remind clinicians of the need to investigate recurrent chest infections for a possible gastrointestinal cause.

    Mini turbo-pumps having a diameter smaller than 100mm are employed in many fields; automobile radiator pump, ventricular assist pump, cooling pump for electric devices, washing machine pump and so on. Further, the needs for mini turbo-pumps would become larger with the increase of the application of it for electrical machines. It is desirable that the mini turbo-pump design is as simple as possible due to restriction to make precise manufactures. But the design method for the mini turbo-pump is not established because the internal flow condition for these small-sized fluid machineries is not clarified and conventional theory is not conductive for small-sized pumps. Three types of rotors with different outlet angles are prepared for an experiment and a numerical analysis. The performance tests are conducted with these rotors in order to investigate the effect of the blade outlet angle on performance and internal flow condition of mini turbo-pumps. It is clarified from the experimental results that head of the mini turbo-pump increases and maximum efficiency flow rate shifts to larger flow rate according to the increase of the blade outlet angle, however the maximum efficiency decreases with the increase of it. In the present paper, the performance of the mini turbo-pump is shown and the internal flow conditions are clarified with the results of the experiment and the numerical flow analysis. Furthermore, the effects of the blade outlet angle on the performance are investigated and high performance design with simple structure for the mini turbo-pump would be considered.

Their evaluation consisted of history along with International Prostate Symptoms Score (IPSS), digital rectal examination (DRE), transabdominal ultrasonography to measure prostate volume, intravesical prostatic protrusion & post voidal residual (PVR) urine and pressure-flow studies to detect bladder outflow obstruction (BOO). Statistical analysis included Unpaired 't' test, Chi-square test and Spearman's Rank correlation test. Receiver Operator Characteristic (ROC) curves were used to compare the correlation of PV and IPP with BOO. Mean prostate volume was significantly larger in bladder outlet obstructed patients (PProstate volume & intravesical prostatic protrusion measured through transabdominal ultrasonography are noninvasive and accessible method that significantly correlates with bladder outlet obstruction in patients with benign prostatic hyperplasia and the correlation of IPP is much more stronger than that of prostate volume.

  13. Improvement of the Efficiency of the Axial-Flow Pump at Part Loads due to Installing Outlet Guide Vanes Mechanism

    Directory of Open Access Journals (Sweden)

    Fan Yang

    2016-01-01

    Full Text Available In order to investigate the influence of adjustable outlet guide vane on the hydraulic performance of axial-flow pump at part loads, the axial-flow pump with 7 different outlet guide vane adjustable angles was simulated based on the RNG k-ε turbulent model and Reynolds time-averaged equations. The Vector graphs of airfoil flow were analyzed in the different operating conditions for different adjustable angles of guide vane. BP-ANN prediction model was established about the effect of adjustable outlet guide vane on the hydraulic performance of axial-flow pump based on the numerical results. The effectiveness of prediction model was verified by theoretical analysis and numerical simulation. The results show that, with the adjustable angle of guide vane increasing along clockwise, the high efficiency area moves to the large flow rate direction; otherwise, that moves to the small flow rate direction. The internal flow field of guide vane is improved by adjusting angle, and the flow separation of tail and guide vane inlet ledge are decreased or eliminated, so that the hydraulic efficiency of pumping system will be improved. The prediction accuracy of BP-ANN model is 1%, which can meet the requirement of practical engineering.

    Aim: In the present study, we investigate the expression of caldesmon (CAD) isoforms in rabbit detrusor smooth muscles (DSM) during the progression of partial bladder outlet obstruction and relate them with the time course of obstruction. Methods: Detrusor samples were obtained from the bladders of rabbits with partial bladder outlet obstruction and sham-operated control rabbits after 1, 2, 4, and 8 weeks of obstruction. Contractile responses to field stimulation and carbachol were determined in the isolated bladder strips. Western blotting was used to determine the relative levels of CaD isoform expression at the protein levels. Results: The contractile responses decreased progressively over the course of obstruction. The expression of 1-CaD increased significantly to approximately the same extent as the 1-4-week obstructed groups and further in the 8-week ob-structed group. The expression of h-CaD increased in all of the obstructed bladders, but at significantly higher levels in the 1-2-week obstructed bladders compared to the control and 4-8-week obstructed bladders. Conclusions: The changes in the isoforms of CaD may be part of the molecular mechanism for bladder compensa-tion following partial bladder outlet obstruction. The overexpression of 1-CaD and the h-CaD/1-CaD ratio could be markers for the status of DSM remodeling and dysfunction.

    Full Text Available In this study the centrifugal pump performances with different blade outlet angles are tested when handling water and viscous oils as Newtonian fluids. Also, this study shows a numerical simulation of the three-dimensional fluid flows inside the centrifugal pump with different blade outlet angles. For these numerical simulations the SIMPLEC algorithm is used for solving governing equations of incompressible viscous/turbulent flows through the pump at different operating conditions. The k-ε turbulence model is adopted to describe the turbulent flow process. These simulations have been made with a steady calculation using the multiple reference frames (MRF technique to take into account the impeller- volute interaction. Numerical results are compared with the experimental characteristic curve for each viscous fluid. The results show that when the outlet angle increases, the centrifugal pump performance handling viscous fluids improves. This improvement is due to decrease of wake at the exit of impeller. Also the results show that the well-known jet/wake flow model is not found in the impeller simulations.

    Full Text Available We carried out investigations for the purpose of clarifying the rotor outlet flow fields with rotating stall cell in a diagonal-flow fan. The test fan was a high–specific-speed (ns=1620 type of diagonal-flow fan that had 6 rotor blades and 11 stator blades. It has been shown that the number of the stall cell is 1, and its propagating speed is approximately 80% of its rotor speed, although little has been known about the behavior of the stall cell because a flow field with a rotating stall cell is essentially unsteady. In order to capture the behavior of the stall cell at the rotor outlet flow fields, hot-wire surveys were performed using a single-slant hotwire probe. The data obtained by these surveys were processed by means of a double phase-locked averaging technique, which enabled us to capture the flow field with the rotating stall cell in the reference coordinate system fixed to the rotor. As a result, time-dependent ensemble averages of the three-dimensional velocity components at the rotor outlet flow fields were obtained. The behavior of the stall cell was shown for each velocity component, and the flow patterns on the meridional planes were illustrated.

    Full Text Available Objective: The aim of this study was to evaluate the trans-axillary surgical approach in patients with thoracic outlet syndrome. Methods: This retrospective study is comprised of data acquired from January 1998 until Oct 2008. Case histories of all the patients were reviewed from the Medical Records Department of Sher-i-Kashmir Institute. Relevant information and follow-up of the patients was carried out by examining the relevant clinical notes available by telephone interviews and personal contact whenever possible. All data was compiled and analyzed statistically. Results: There were a total of 139 patients. The female: male ratio was about 6:1. Pain was the most common presenting symptom followed by weakness and parasthesia. Nerve conduction velocity was abnormal in 111 patients. Twenty-eight patients had abnormal Doppler study of subclavian vessels. Preoperative symptoms persisted in 13 patients. Overall, 126 patients showed improvement in symptoms and no recurrence or persistence of symptoms on follow-up examination. Conclusion: Trans-axillary approach provides a good exposure and cosmesis in patients with thoracic outlet syndrome. It should be considered as the gold standard in the management of thoracic outlet syndrome.

    Zeolites can adsorb small organic molecules such as alcohols from a fermentation broth. Also in the zeolite-catalyzed conversion of alcohols to biofuels, biochemicals, or gasoline, adsorption is the first step. Several studies have investigated the adsorption of alcohols in different zeolites experimentally, but computational investigations in this field have mostly been restricted to zeolite MFI. In this study, the adsorption of C1-C4 alcohols in BEA and MOR was investigated using density functional theory (DFT). Calculated adsorption geometries and the corresponding energies of the designed cluster models were comparable to periodic calculations, and the adsorption energies were in the same range as the corresponding computational and experimental values reported in the literature for zeolite MFI. Thus, BEA and MOR may be good adsorption materials for alcohols in the field of downstream processing and catalysis. Aside from the DFT calculations, adsorption isotherms were determined experimentally in this study from aqueous solutions. For BEA, the adsorption of significant amounts of alcohol from aqueous solution was observed experimentally. In contrast, MOR was loaded with only a very small amount of alcohol. Although differences were found between the affinities obtained from gas-phase DFT calculations and those observed experimentally in aqueous solution, the computational data presented here represent molecular level information on the geometries and energies of C1-C4 alcohols adsorbed in zeolites BEA and MOR. This knowledge should prove very useful in the design of zeolite materials intended for use in adsorption and catalytic processes, as it allows adsorption behavior to be predicted via judiciously designed computational models.

    Full Text Available Alcohol consumption within elite sport has been continually reported both anecdotally within the media and quantitatively in the literature. The detrimental effects of alcohol on human physiology have been well documented, adversely influencing neural function, metabolism, cardiovascular physiology, thermoregulation and skeletal muscle myopathy. Remarkably, the downstream effects of alcohol consumption on exercise performance and recovery, has received less attention and as such is not well understood. The focus of this review is to identify the acute effects of alcohol on exercise performance and give a brief insight into explanatory factors.

    An overview with respect to the identification of patients with risky drinking, alcohol abuse or alcohol dependence is given. As a first step, a simple screening questionnaire should be used. Self-statements in standardized questionnaires are more valid than standard laboratory markers. A useful instrument is for example BASIC. In screening positive patients, an in-depth diagnosis is necessary and helps to distinguish between different forms of problematic alcohol use. Depending on the severity of the alcohol problem, brochures, internet-programs, counselling or referral to treatment services is helpful.
