    "There is, indeed, little doubt,” the formidable scholar James Orchard Halliwell-Phillipps confidently explained to the Victorian readers of his Outlines of the Life of Shakespeare, “that the Birth-place did not become one of the incentives for pilgrimage until public attention had been specially directed to it at the time of the Jubilee.” That's broadly true. The earliest reference to the three-gabled, half-timbered house (two houses, originally) on Henley Street in Stratford-upon-Avon as th...

    Lumbini, in southern Nepal, is a UNESCO world heritage site of universal value as the birthplace of the Buddha. Poor air quality in Lumbini and surrounding regions is a great concern for public health as well as for preservation, protection and promotion of Buddhist heritage and culture. Measurements of the ambient concentrations of key air pollutants (BC, PM, CO, O3) were conducted in Lumbini, first of its kind in Lumbini, during an intensive measurement period of three months (April-June 2013) in the pre-monsoon season. The measurements were carried out as a part of the international air pollution measurement campaign; SusKat-ABC (Sustainable Atmosphere for the Kathmandu Valley - Atmospheric Brown Clouds). Hourly average concentrations were: BC: 4.9±3.8 (0.3-29.9) μg/m3; CO: 344.1±160.3 (124.9-1429.7) ppbv; O3: 46.6±20.3 (0.85-118.1) ppbv; PM10: 128.8±91.9 (10.5-603.9) μg/m3; and PM2.5: 53.1±35.1 (6.1-272.2) μg/m3. These levels are comparable to heavily polluted sites in the region. The 24-h average PM2.5 and PM10 concentrations frequently (94% and 85%, respectively, of the sampled period) exceeded the WHO guideline, which implies significant health risks for the residents and visitors in the region. Clear diurnal cycles were observed for the pollutants. Occurrences of peak concentrations during the study period were due to regional forest fires and meteorological conditions conducive of transport to Lumbini. The WRF-STEM model was used to simulate the meteorology and the pollution concentration, and showed the model concentration to be lower by a factor of ~1.4-5, even though the model was able to capture the observed variability. Regionally tagged CO tracers and the chemical composition of fine mode PM2.5 was obtained from the model. The aerosol spectral light absorption coefficients obtained from Lumbini indicated presence of BC from both biomass burning and fossil fuel combustion, with more than half of the ambient BC attributable to fossil fuel

    These remotely sensed, geographically referenced elevation measurements of Lidar-derived bare earth (BE) and first surface (FS) topography were produced as a collaborative effort between the U.S. Geological Survey (USGS), Florida Integrated Science Center (FISC), St. Petersburg, FL; the National Park Service (NPS), Northeast Coastal and Barrier Network, Kingston, RI; and the National Aeronautics and Space Administration (NASA), Wallops Flight Facility, VA. This project provides highly detailed and accurate datasets of the George Washington Birthplace National Monument in Virginia, acquired on March 26, 2008. The datasets are made available for use as a management tool to research scientists and natural resource managers. An innovative airborne Lidar instrument originally developed at the NASA Wallops Flight Facility, and known as the Experimental Advanced Airborne Research Lidar (EAARL) was used during data acquisition. The EAARL system is a raster-scanning, waveform-resolving, green-wavelength (532-nanometer) Lidar designed to map near-shore bathymetry, topography, and vegetation structure simultaneously. The EAARL sensor suite includes the raster-scanning, water-penetrating full-waveform adaptive Lidar, a down-looking red-green-blue (RGB) digital camera, a high-resolution multi-spectral color infrared (CIR) camera, two precision dual-frequency kinematic carrier-phase GPS receivers, and an integrated miniature digital inertial measurement unit, which provide for submeter georeferencing of each laser sample. The nominal EAARL platform is a twin-engine Cessna 310 aircraft, but the instrument may be deployed on a range of light aircraft. A single pilot, a Lidar operator, and a data analyst constitute the crew for most survey operations. This sensor has the potential to make significant contributions in measuring sub-aerial and submarine coastal topography within cross-environmental surveys. Elevation measurements were collected over the survey area using the EAARL

    Induced abortion (IA) has shown social inequality related to birthplace and education with higher rates of IAs in immigrant and in less educated women relative to their native and highly educated counterparts. This study examined the independent and joint effects of birthplace and education on IA, repeated and IA performed during the 2nd trimester of pregnancy among women residing in the Basque Country, Spain. We conducted a cross-sectional population-based study of IA among women aged 25-49 years residing in the Basque Country, Spain, between 2011 and 2013. Log-binomial regression was used to quantify the independent and joint effects of birthplace and education attainment on all outcomes. Immigrant women exhibited higher probability of having an IAs (PR: 5.31), a repeated (PR: 7.23) or a 2nd trimester IAs (PR: 4.07) than women born in Spain. We observed higher probabilities for all outcomes among women with a primary or less education relative to those with a graduate education (All IAs PR: 2.51; repeated PR: 6.00; 2nd trimester PR: 3.08). However, no significant heterogeneity was observed for the effect of education on the association of birthplace with IAs, repeated or 2nd trimester IAs. Birthplace and education are key factors to explain not only an IA decision but also having a repeated or a 2nd trimester IA. However, the effects of birthplace and education may be independent from each other on these outcomes. A better understanding of these factors on IAs is needed when designing programs for sexual and reproductive health aimed to reduce inequalities among women.

    The purpose of this study was to explore variations in demographics, culture, self-esteem and intimate partner violence among Hispanic women according to birthplace, and to identify factors that are associated with these differences in intimate partner violence. Baseline data from a randomized control trial testing the efficacy of an HIV prevention program was used. Path analyses identified differences in intimate partner violence between Colombian women and women from other Central/South American. Self-esteem was the only factor that was associated with these differences. Interventions that address the unique needs of Hispanic women from different subgroups are needed. PMID:23363655

    Located in the central plains and the eastern slope of songhsan, Xinmi has a long history and unique advantage in environment. As the birthplace of Qi-Huang culture, it has abundant Qibo and Huangdi relics (Xuanyuan tpe, Qibo tomb, Qibo temple, Qibo spring, Huangdi palace and Qibo mountain), folk tales about their academic discussion which were popular long time ago, many archaeological discoveries with academic value and genuine Chinese medicinal materials. Qi-Huang culture is the valuable Chinese culture heritage and it needs to be further studied and developed.

    Although birthplace and length of residence have been found to be associated with Body Mass Index (BMI)/obesity in the USA, their effects may not be the same across groups defined by education, gender and race/ethnicity. Using cross-sectional population based data from the 2001 California Health Interview Survey, we investigated the associations of birthplace and US length of residence with BMI, and whether the influence of birthplace-US length of residence on BMI varied by education, gender and race/ethnicity. Our sample included 37,350 adults aged 25-64 years. Self-reported weight and height were used to calculate BMI. Birthplace and length of residence were combined into a single variable divided into five levels: US-born, foreign-born living in the United States for more than 15, 10-14, 5-9, and less than 5 years. Controlling for age, gender, marital status, race/ethnicity, education, income, fruit and vegetable consumption, current smoking and alcohol use, we found that: (1) foreign-born adults had lower BMI than US-born adults; (2) among foreign-born adults, longer residence in the United States was associated with higher BMI; and (3) the effect of birthplace-length of US residence on BMI differed by education level, gender and race/ethnicity. Specifically, longer residence in the United States was associated with the greatest percent increases in BMI among the lowest educated groups than higher educated groups, among women (vs. men) and among Hispanics (vs. other racial/ethnic groups). These findings suggest that a protective effect of foreign birthplace on BMI appears to attenuate with length of residence in the United States, and also reveal that BMI/obesity trajectories associated with length of US residence vary by education, gender and race/ethnicity. Immigrant status, independently and in combination with education, gender and race/ethnicity should be considered in future obesity prevention and reduction efforts.

    2010-01-01

    Modern embryology is grounded on the research of Pander (theory of germ-layers), von Baer (human egg) and Rathke (branchial arches in mammals). All these scientists lived and worked in the Baltic region. They held professorships at the universities of Koenigsberg and Dorpat and at the Imperial Academy of St. Petersburg, thus moving between the Kingdom of Prussia and the Russian Czardom. Since the Baltic countries are not commonly considered to be predestined as a birthplace of embryology, special attention is turned to the coincidences that, there of all places, made those people focus on that special field of research. Considering the peripheral position of the Baltic, the paper examines personal relations, national identities, cultural exchange, and local working conditions, including room for development as well as formidable obstacles.

  18. White spotting variant (Wv) mouse as an experimental model for ovarian aging and menopausal biology

    2011-01-01

    Objective Menopause is a unique phenomenon in modern women, as most mammalian species possess a reproductive period comparable to their lifespan. Menopause is caused by the depletion of germ cell-containing ovarian follicles, and in laboratory studies is usually modeled in animals in which the ovarian function is removed by ovariectomy or chemical poisoning of the germ cells. Our objective was to explore and characterize the white spotting variant (Wv) mice that have reduced ovarian germ cell abundance, a result of a point mutation in the c-kit gene that decreases the kinase activity, as a genetic model for use in menopausal studies. Methods Physiological and morphological features associated with menopause were determined in female Wv/Wv mice compared to age-matched wildtype controls. Immunohistochemistry was used to evaluate the presence and number of follicles in paraffin-embedded ovaries. Bone density and body composition were evaluated using the PIXImus X-ray densitometer, and lipids, calcium, and hormone levels were determined in serum using antigen-specific EIAs. Heart and body weight were measured, and cardiac function was evaluated by transthoracic echocardiography. Results The ovaries of the Wv/Wv females have a greatly reduced number of normal germ cells at birth compared to wildtype mice. The remaining follicles are depleted by around 2 months, and the ovaries develop benign epithelial lesions that resemble morphological changes that occur during ovarian aging, whereas a normal mouse ovary has numerous follicles at all stages of development and retains some follicles even in advanced age. Wv mice have elevated plasma gonadotrophins and reduced estrogen and progesterone levels, a significant reduction in bone mass density, and elevated serum cholesterol and lipoprotein levels. Moreover, the Wv female mice have enlarged hearts and reduced cardiac function. Conclusions The reduction of c-kit activity in Wv mice leads to a substantially diminished

    to explore women׳s birthplace decision-making and identify the factors which enable women to plan to give birth in a freestanding midwifery-led primary level maternity unit rather than in an obstetric-led tertiary level maternity hospital in New Zealand. a mixed methods prospective cohort design. data from eight focus groups (37 women) and a six week postpartum survey (571 women, 82%) were analysed using thematic analysis and descriptive statistics. The qualitative data from the focus groups and survey were the primary data sources and were integrated at the analysis stage; and the secondary qualitative and quantitative data were integrated at the interpretation stage. Christchurch, New Zealand, with one tertiary maternity hospital and four primary level maternity units (2010-2012). well (at 'low risk' of developing complications), pregnant women booked to give birth in one of the primary units or the tertiary hospital. All women received midwifery continuity of care, regardless of their intended or actual birthplace. five core themes were identified: the birth process, women׳s self-belief in their ability to give birth, midwives, the health system and birth place. 'Confidence' was identified as the overarching concept influencing the themes. Women who chose to give birth in a primary maternity unit appeared to differ markedly in their beliefs regarding their optimal birthplace compared to women who chose to give birth in a tertiary maternity hospital. The women who planned a primary maternity unit birth expressed confidence in the birth process, their ability to give birth, their midwife, the maternity system and/or the primary unit itself. The women planning to give birth in a tertiary hospital did not express confidence in the birth process, their ability to give birth, the system for transfers and/or the primary unit as a birthplace, although they did express confidence in their midwife. birthplace is a profoundly important aspect of women׳s experience of

    Birth in primary midwife-led maternity units has been demonstrated to be a safe choice for well women anticipating a normal birth. The incidence of serious perinatal outcomes for these women is comparable to similarly low risk women, who choose to birth in hospital. New Zealand women have a choice of Lead Maternity Carer (LMC) and birthplace; home, primary birthing unit, or a base hospital, though not all women may have all these choices available locally. Women in rural and rural remote areas can also choose to birth in their rural primary maternity unit. A percentage of these women (approx. 15-17%) will require transfer during labour, an event which can cause distress and often loss of midwifery continuity of care. To explore retrospectively the choice of birth place decisions and the labour and birth experiences of a sample of women resident in remotely zoned, rural areas of the lower South Island of New Zealand. A purposive sample of women living in remote rural areas, recruited by advertising in local newspapers and flyers. Individual semi-structured interviews were digitally recorded using a pragmatic interpretive approach. The data (transcripts and field notes) were analysed using thematic and content analysis. Ethical approval was obtained from the Health and Disability Ethics Committee (HEDC) MEC/06/05/045. Thirteen women consented to participate. Each was resident in a remote rural area having given birth in the previous 18 months. The women had been well during their pregnancies and at the onset of labour had anticipated a spontaneous vaginal birth. Rural remote zoned areas in Otago and Southland in the South Island of New Zealand FINDINGS: Five women planned to birth in a regional hospital and eight chose their nearest rural primary maternity unit. All of the women were aware of the possibility of transfer and had made their decision about their birthplace based on their perception of their personal safety, and in consideration of their distance from

    To examine relative age and birth place effects in hockey players drafted to play in the National Hockey League (NHL) between 2000 and 2005 and determine whether these factors influenced when players were chosen in the draft. 1013 North American draftees were evaluated from the official NHL website, which provided birthplace, date of birth and selection order in the draft. Population size was collected from Canadian and American census information. Athletes were divided into four quartiles on the basis of selection date to define age cohorts in hockey. Data between the Canadian and American players were also compared to see if the optimal city sizes differed between the two nations. Relative age and birthplace effects were found, although the optimal city size found was dissimilar to that found in previous studies. Further, there were inconsistencies between the Canadian and American data. Contextual factors such as relative age and size of birthplace have a significant effect on likelihood of being selected in the NHL draft.

  2. Homebirth as systems-challenging praxis: knowledge, power, and intimacy in the birthplace.

    2008-02-01

    In this article, I examine the processes and motivations involved when women in the United States choose to circumvent the dominant obstetric care paradigm by delivering at home with a group of care providers called direct-entry midwives. Using grounded theory, participant observation, and open-ended, semistructured interviewing, I collected and analyzed homebirth narratives from a theoretical sample of women (n = 50) in two research locales. Findings interpreted from the perspective of critical medical anthropology suggest that women who choose to birth at home negotiate fears associated with the "just in case something bad happens" argument that forms the foundation for hospital birth rationales through complex individual and social processes. These involve challenging established forms of authoritative knowledge, valuing alternative and more embodied or intuitive ways of knowing, and knowledge sharing through the informed consent process. Adherence to subjugated discourses combined with lived experiences of personal power and the cultivation of intimacy in the birthplace fuel homebirth not only as a minority social movement, but also as a form of systems-challenging praxis.

  3. Religious Tourism and TV Serials: the Case of Two Italian Papal Birthplaces

    2014-12-01

    Full Text Available In this paper the authors examine two of Italy’s lesser religious tourism destinations: Sotto il Monte and Concesio, small towns in northern Italy which have the distinction of being the birthplaces of Pope John XXIII and Pope Paul VI. In 2002 and 2008 respectively, two of the country’s national television networks broadcast during prime time short television serials dedicated to the two popes. Despite being very successful with the viewing public, the serials proved to have little impact in terms of tourism, as demonstrated by comprehensive tourist surveys and in-depth conversations with the parties concerned. The aim of the present research is to ascertain, using a visual geographical research approach, whether the reasons for this can be identified, taking account of the pull factors of place, personality and performance referred to by Macionis in 2004. In the first part of the study the authors put forward a definition of film-induced religious tourism based on the commonly agreed definitions of film-induced tourism and religious tourism, and outline the unique characteristics ofItaly’s religious-themed television productions. In the second part the two case studies are analysed, with an outline of the geographical features of the locations and biographical aspects of the two men, and an assessment of the degree of success in terms of tourism achieved by their home towns, with particular reference to the years following the screening of the TV serials.

    For the first time, aerosol optical properties are measured over Lumbini, Nepal, with CIMEL sunphotometer of the Aerosol Robotic Network (AERONET) program. Lumbini is a sacred place as the birthplace of Lord Buddha, and thus a UNESCO world heritage site, located near the northern edge of the central Indo-Gangetic Plains (IGP) and before the Himalayan foothills (and Himalayas) to its north. Average aerosol optical depth (AOD) is found to be 0.64 ± 0.38 (0.06-3.28) over the sampling period (January 2013-December 2014), with the highest seasonal AOD during the post-monsoon season (0.72 ± 0.44). More than 80% of the daily averaged AOD values, during the monitoring period, are above 0.3, indicating polluted conditions in the region. The levels of aerosol load observed over Lumbini are comparable to those observed at several heavily polluted sites in the IGP. Based on the relationship between AOD and Ångstrom exponent (α), anthropogenic, biomass burning, and mixed aerosols are found to be the most prevalent aerosol types. The aerosol volume-size distribution is bi-modal during all four seasons with modes centered at 0.1-0.3 and 3-4 μm. For both fine and coarse modes, the highest volumetric concentration of ~ 0.08 μm -3  μm -2 is observed during the post-monsoon and pre-monsoon seasons. As revealed by the single-scattering albedo (SSA), asymmetry parameter (AP), and refractive index (RI) analyses, aerosol loading over Lumbini is dominated by absorbing, urban-industrial, and biomass burning aerosols.

    Ruberg, L. F.; Calinger, M.

    2014-12-01

    The National Research Council Framework for K-12 Science Literacy reports that children reared in rural agricultural communities, who experience regular interactions with plants and animals, develop more sophisticated understanding of ecology and biological systems than do urban and suburban children of the same age. West Virginia (WV) is a rural state. The majority of its residents live in communities of fewer than 2,500 people. Based on the features of the population being served and their unique strengths, this presentation focuses on a regional model for teacher professional development that addresses agricultural and energy vulnerabilities and adaptations to climate change in WV. The professional development model outlined shows how to guide teachers to use a problem-based learning approach to introduce climate data and analysis techniques within a scenario context that is locally meaningful. This strategy engages student interest by focusing on regional and community concerns. Climate science standards are emphasized in the Next Generation Science Standards, but WV has not provided its teachers with appropriate instructional resources to meet those standards. The authors addressed this need by offering a series of climate science education workshops followed by online webinars offered to WV science educators free of charge with funding by the West Virginia Space Grant Consortium. The authors report on findings from this series of professional development workshops conducted in partnership with the West Virginia Science Teachers Association. The goal was to enhance grades 5-12 teaching and learning about climate change through problem-based learning. Prior to offering the climate workshops, all WV science educators were asked to complete a short questionnaire. As Figure 1 shows, over 40% of the teacher respondents reported being confident in teaching climate science content. For comparison post workshops surveys measure teacher confidence in climate science

    women are more likely to give birth at a health facility when their families agree with the birthplace. However, in rural areas of Tanzania, women are often marginalized from decision-making. This study predicted birthplace intention and identified factors to reduce perceptional gaps among pregnant women, husbands and family members. explanatory cross-sectional survey was conducted in three villages in North Eastern Tanzania. Participants were 138 pregnant women and their families who answered the Birth Intention Questionnaire (BIQ), measuring knowledge, attitude, perceived behavioral control, subjective norms and intention for birthplace. Descriptive analysis, ANOVA, Chi-square, and multiple linear regression was used to analyze the data. the regression model showed that knowledge, perceived behavioral control, and subjective norms predicted intention for birthplace (R2 = .28). While 81% of pregnant women thought their husbands were decision-makers for their birth, only 38% of husbands and 37% of family members agreed. Pregnant women had significantly lower scores on the item "I will prepare for childbirth with my family" compared with husbands (p Chi-cuadrado y regresión lineal múltiple para analizar los datos. el modelo de regresión mostró que el conocimiento, la percepción de control del comportamiento, y las normas subjetivas predijeron la intencion del lugar de parto (R2 = 0,28). Mientras que el 81% de las mujeres embarazadas pensaba que sus maridos estaban encargados de tomar decisiones para el nacimiento, sólo el 38% de los esposos y el 37% de los miembros de la familia estuvieron de acuerdo. Las mujeres embarazadas tenían puntuaciones significativamente más bajas en el tema "Me prepararé para el parto con mi familia", en comparación con los maridos (p < 0,01) y otros miembros de la familia (p < 0,001). proporcionar la preparación al parto basada en la evidencia y reducir las brechas de percepción identificadas pueden mejorar intención de las

    Macrobenthos and physical/chemical factors known to affect their abundance were monitored near the Calvert Cliffs nuclear power plant on the mainstem of the Chesapeake Bay between 1971 and 1982. These data, along with data collected near the Morgantown power plant on the Potomac between 1980 and 1983, were used to quantify the variation in macrobenthos due to natural spatial patterns, seasonal dynamics, year-to-year fluctuations in abundance, and power plant operations, as well as to determine if long-term trends in populations or communities occurred. Macrobenthic community structure was persistent over the 11 years within bounds determined chiefly by year-to-year variation in salinity and dissolved oxygen concentration. Most of the species responded to changes in salinity by predictable increases or decreases in abundance

  2. Enhanced Reconstitution of Human Erythropoiesis and Thrombopoiesis in an Immunodeficient Mouse Model with KitWv Mutations

    Full Text Available In human-to-mouse xenograft models, reconstitution of human hematopoiesis is usually B-lymphoid dominant. Here we show that the introduction of homozygous KitWv mutations into C57BL/6.Rag2nullIl2rgnull mice with NOD-Sirpa (BRGS strongly promoted human multi-lineage reconstitution. After xenotransplantation of human CD34+CD38− cord blood cells, these newly generated C57BL/6.Rag2nullIl2rgnullNOD-Sirpa KitWv/Wv (BRGSKWv/Wv mice showed significantly higher levels of human cell chimerism and long-term multi-lineage reconstitution compared with BRGS mice. Strikingly, this mouse displayed a robust reconstitution of human erythropoiesis and thrombopoiesis with terminal maturation in the bone marrow. Furthermore, depletion of host macrophages by clodronate administration resulted in the presence of human erythrocytes and platelets in the circulation. Thus, attenuation of mouse KIT signaling greatly enhances the multi-lineage differentiation of human hematopoietic stem and progenitor cells (HSPCs in mouse bone marrow, presumably by outcompeting mouse HSPCs to occupy suitable microenvironments. The BRGSKWv/Wv mouse model is a useful tool to study human multi-lineage hematopoiesis.

    Evaluation of the fate and transport of carbon dioxide (CO2) in deep reservoirs is crucial to the development of long-term geologic carbon sequestration (GCS) technologies. In this report, various studies using computed tomography (CT) scanning are utilized in conjunction with traditional flow tests to observe the multi-scale phenomena associated with CO2 injection in geologic media. Pore scale analyses were performed to determine the infiltration characteristics of CO2 into a brine saturated reservoir rock. Multiphase floods were performed to evaluate the saturation of CO2 into a brine-saturated reservoir rock and determine how structural changes within the lithology affect such interactions. Additionally, CO2 induced swelling of unconventional reservoir rock was evaluated with respect to reductions in fracture transmissivity due to matrix swelling. These studies are just a few examples of the benefits of multi-scale CT imaging in conjunction with traditional laboratory methodology to gain a better understanding of the interactions between CO2 and the lithologies it interacts with during GCS.

    W and W-V alloys reinforced with La{sub 2}O{sub 3} particles have been produced by MA and subsequent HIP at 1573 K and 195 MPa. The microstructure of the consolidated alloys has been characterized by scanning electron microscopy, energy dispersive spectroscopy analyses and X-ray diffraction. The mechanical properties were studied by nanoindentation measurements. The results show that practically full dense billets of W-V, W-V-La{sub 2}O{sub 3} and W-La{sub 2}O{sub 3} alloys can be produced. The microstructure analysis has shown that islands of V are present in W-V and W-V-1La{sub 2}O{sub 3} alloys. In W-1La{sub 2}O{sub 3} islands of La{sub 2}O{sub 3} are also present. The nanohardness of the W matrix increases with the addition of V, while decreases with the addition of La{sub 2}O{sub 3}.

    Current clinical guidelines and national policy in England support offering 'low risk' women a choice of birth setting. Options include: home, free-standing midwifery unit (FMU), alongside midwifery unit (AMU) or obstetric unit (OU). This study, which is part of a broader project designed to inform policy on 'choice' in relation to childbirth, aimed to provide evidence on UK women's experiences of choice and decision-making in the period since the publication of the Birthplace findings (2011) and new NICE guidelines (2014). This paper reports on findings relating to women's information needs when making decisions about where to give birth. A qualitative focus group study including 69 women in the last trimester of pregnancy in England in 2015-16. Seven focus groups were conducted online via a bespoke web portal, and one was face-to-face. To explore different aspects of women's experience, each group included women with specific characteristics or options; planning a home birth, living in areas with lots of choice, living in areas with limited choice, first time mothers, living close to a FMU, living in opt-out AMU areas, living in socioeconomically disadvantaged areas and planning to give birth in an OU. Focus group transcripts were analysed thematically. Women drew on multiple sources when making choices about where to give birth. Sources included; the Internet, friends' recommendations and experiences, antenatal classes and their own personal experiences. Their midwife was not the main source of information. Women wanted the option to discuss and consider their birth preferences throughout their pregnancy, not at a fixed point. Birthplace choice is informed by many factors. Women may encounter fewer overt obstacles to exercising choice than in the past, but women do not consistently receive information about birthplace options from their midwife at a time and in a manner that they find helpful. Introducing options early in pregnancy, but deferring decision

  8. Inflammation induced by mast cell deficiency rather than the loss of interstitial cells of Cajal causes smooth muscle dysfunction in W/Wv mice

    The initial hypothesis suggested that the interstitial cells of Cajal (ICC) played an essential role in mediating enteric neuronal input to smooth muscle cells. Much information for this hypothesis came from studies in W/Wv mice lacking ICC. However, mast cells, which play critical roles in regulating inflammation in their microenvironment, are also absent in W/Wv mice. We tested the hypothesis that the depletion of mast cells in W/Wv mice generates inflammation in fundus muscularis externa (ME) that impairs smooth muscle reactivity to Ach, independent of the depletion of ICC. We performed experiments on the fundus ME from wild type (WT) and W/Wv mice before and after reconstitution of mast cells by bone marrow transplant. We found that mast cell deficiency in W/Wv mice significantly increased COX-2 and iNOS expression and decreased smooth muscle reactivity to Ach. Mast cell reconstitution or concurrent blockade of COX-2 and iNOS restored smooth muscle contractility without affecting the suppression of c-kit in W/Wv mice. The expression of nNOS and ChAT were suppressed in W/Wv mice; mast cell reconstitution did not restore them. We conclude that innate inflammation induced by mast cell deficiency in W/Wv mice impairs smooth muscle contractility independent of ICC deficiency. The impairment of smooth muscle contractility and the suppression of the enzymes regulating the synthesis of Ach and NO in W/Wv mice need to be considered in evaluating the role of ICC in regulating smooth muscle and enteric neuronal function in W/Wv mice.

  9. Effect of heat treatment on the microstructure of a 2CrMoNiWV rotor steel

    Science.gov (United States)

    Li, Cheng

    A wide range of experiments have been carried out on a 2CrMoNiWV low alloy steel to investigate the effect of various heat treatment conditions on microstructural change, alloy carbide transformation mechanism and mechanical properties.Two complete continuous cooling transformation (CCT) diagrams were constructed for this steel on the basis of experimental dilatometry thermal analysis, metallographic examination and current phase transformation theory. The significance of these two diagrams is in that they can be directly utilised in industrial practice as a reference during heat treatment for this material. Meanwhile it was confirmed that this 2CrMoNiWV steel can be transformed to a fully bainitic microstructure over a wide range of cooling rates and this feature proved this steel suitable for large diameter steam turbine rotor application.An innovative carbide extraction technique for the XRD identification of carbide phase has been developed. The detailed description of this new technique and its advantages are discussed in this thesis. The extensive work using TEM/EDX has set up essential "finger prints" for the quick examination of large amounts of individual carbide existing at various heat treated conditions. Simultaneous measurements and determinations were made on particle composition, morphological change, the type, amount and distribution of these carbide phases. Thus the sequence of carbide transformation for this 2CrMoNiWV steel during tempering has been established.The characteristic microstructures of various heat treated specimens were carefully examined and discussed. Theoretical thermodynamic equilibria predictions were calculated using MTDATA. A very good agreement was found between experimental results and theoretical predictions on those critical transformation temperatures and a good correlation of carbide evolution sequences was obtained. Based on experimental results and theoretical predictions, the role of tungsten in promoting creep

    A novel species, Flavobacterium kingsejongi WV39, isolated from feces of Antarctic penguins and a type species of the genus Flavobacterium, is yellow because it synthesizes a C40 carotenoid zeaxanthin. The complete genome of F. kingsejongi WV39 is made up of a single circular chromosome (4,224,053bp, 39.8% G+C content). Annotation analysis revealed 3,955 coding sequences, 72 RNAs (18 rRNA+54 tRNA), and five genes involved in zeaxanthin biosynthesis. The key gene encoding β-carotenoid hydroxylase (CrtZ), which is the last enzyme in the zeaxanthin biosynthetic pathway, was cloned and subjected to complementary analysis in a heterologous E. coli strain. The CrtZ of F. kingsejongi WV39 showed a higher activity than other reported CrtZs. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Aim: A prospective study was undertaken to evaluate the use of 2% (w/v alcoholic chlorhexidine gluconate (2% AlcCHG in donor arm preparation, to monitor the contamination rate of blood products after the collection and to find incidence of transfusion associated bacteremia. Settings and Design: Optimal skin antisepsis of the phlebotomy site is essential to minimize the risk of contamination. Food and Drug Administration (FDA in India has recommended antisepsis with three-step regimen of spirit-10% povidone iodine-spirit for donor arm antisepsis, but not with chlorhexidine, which is recommended by many other authors. Material and Methods: A total of 795 donors were studied from July 2011 to January 2012. Spirit-10% povidone iodine-spirit was used for 398 donors and 2% AlcCHG was used for 397 donors with the two-step method for arm antisepsis. Swabs were collected before and after use of antiseptic agents for all the donors. All the blood products collected from donors with growth in post-antisepsis swabs were cultured. A total of 123 various blood products were cultured irrespective of the method and result of antisepsis was observed. A total of seven patients had mild transfusion reaction. The transfused blood products, blood and urine specimen of the patients who had transfusion reaction were also cultured. Results: Seven donors out of 398 donors had growth in post-antisepsis swab with spirit-10% povidone iodine-spirit protocol and three donors out of 397 donors had growth in post-antisepsis swab with 2% AlcCHG protocol. All blood products collected from donors who had growth in post-antisepsis swabs when cultured had no growth. There was no contamination of blood products. Conclusions: Two percent (w/v alcoholic chlorhexidine gluconate with two-step protocol can be used as an antiseptic agent for donor arm preparation without considerable cost difference. It is at par with spirit 10% povidone iodine spirit protocol as suggested by FDA in India

    To explore and compare perinatal and maternal outcomes in women at 'higher risk' of complications planning home versus obstetric unit (OU) birth. Prospective cohort study. OUs and planned home births in England. 8180 'higher risk' women in the Birthplace cohort. We used Poisson regression to calculate relative risks adjusted for maternal characteristics. Sensitivity analyses explored possible effects of differences in risk between groups and alternative outcome measures. Composite perinatal outcome measure encompassing 'intrapartum related mortality and morbidity' (intrapartum stillbirth, early neonatal death, neonatal encephalopathy, meconium aspiration syndrome, brachial plexus injury, fractured humerus or clavicle) and neonatal admission within 48 hours for more than 48 hours. Two composite maternal outcome measures capturing intrapartum interventions/adverse maternal outcomes and straightforward birth. The risk of 'intrapartum related mortality and morbidity' or neonatal admission for more than 48 hours was lower in planned home births than planned OU births [adjusted relative risks (RR) 0.50, 95% CI 0.31-0.81]. Adjustment for clinical risk factors did not materially affect this finding. The direction of effect was reversed for the more restricted outcome measure 'intrapartum related mortality and morbidity' (RR adjusted for parity 1.92, 95% CI 0.97-3.80). Maternal interventions were lower in planned home births. The babies of 'higher risk' women who plan birth in an OU appear more likely to be admitted to neonatal care than those whose mothers plan birth at home, but it is unclear if this reflects a real difference in morbidity. Rates of intrapartum related morbidity and mortality did not differ statistically significantly between settings at the 5% level but a larger study would be required to rule out a clinically important difference between the groups. © 2015 The Authors.

    We report Goldstone delay-Doppler radar imaging of four NEAs obtained during February-June 2017. The signal-to-noise ratios were very strong for each object and we obtained detailed images with range resolutions as fine as 3.75 m/pixel. Delay-Doppler imaging revealed that 2017 BQ6 is a strikingly angular object roughly ~200 m in diameter with a rotation period of ~3 h. The multi-faceted shape is puzzling assuming a rubble-pile structure of this asteroid. 2017 CS was discovered by Pan-STARRS 1 on February 2 and approached within 8 lunar distances on May 29. 2017 CS appears rounded on large scales but has considerable fine-scale topography evident along its leading edges. The images suggest a diameter of ~1 km and rotation visible in the images is consistent with the 40 h rotation period obtained independently by from photometry by P. Pravec (pers. comm.). The highest resolution images show evidence for meter-size boulders, ridges, and broad concavities. 2007 WV4 was imaged in late May and early June. 2007 WV4 appears distinctly angular, with a diameter in the realm of 900 meters, and with at least three large facets more than 100 m in extent. Tracking of features in the images gives a rotation period of about 12 hours. The echoes show a persistent, small topographic feature that extends out from the surface. The nature of this feature is unknown, but it may be a large boulder similar to Yoshinodai seen on 25143 Itokawa. 2014 JO25 approached within 4.6 lunar distances on April 19. This was the closest encounter by an asteroid with an absolute magnitude brighter than 18 known in advance until 2027, when 1999 AN10 will approach within one lunar distance. Radar imaging shows that 2014 JO25 is an irregular object, which consists of two components connected by a narrow neck. The asteroid has a long axis of about 1 km and a short axis of roughly 600 m. The 3.75 m range resolution imaging placed thousands of pixels on the object and reveals ridges, hills, concavities, flat

    Lags of accommodation in ametropic children are often evaluated through spectacle lenses (over-refraction). This study investigated the validity of over-refraction when using an autorefractor. Using an autorefractor (Shin-Nippon SRW-500/Grand-Seiko WV-500), refractive readings were obtained in 25 cyclopleged eyes (mean +/- S.D. refraction: -3.44 +/- 3.56 D, range: from -10.56 to +0.25 D) while placing spherical lenses of different power (from -5.00 to +5.00 D) in front of the eye at a vertex distance of 12 mm. Based on the refractive readings with and without the lens, and the lens power, measurement errors were estimated. Similarly, the measurement errors were estimated also in model eyes of -10.00, -4.75, 0.00 and +10.00 D. The results were compared with ray-tracing simulations based on the internal specifications of the autorefractor. Measurement errors were found unless the power of the spectacle lens was equal to the refractive error of the eye. When the spectacle lens power was greater (less myopic or more hyperopic) than the refraction of the eye, the measurement error was negative in sign and greater than -0.3 D. It follows that, when an accommodative response is measured in myopic subjects, the refractive reading usually becomes more myopic than the refraction of the eye including the accommodative response; hence, the accommodative response is overestimated, and the lag of accommodation is underestimated. The autorefraction through spectacle lenses involved systematic measurement errors. The extent of the errors is usually small but needs to be taken into account in a comparative study of accommodative responses among different refractive groups.

    This study was designed to assess the physicochemical stability of colloidal ferric carboxymaltose solution (Ferinject) when diluted and stored in polypropylene (PP) bottles and bags for infusion. Two batches of ferric carboxymaltose solution (Ferinject) were diluted (500 mg, 200 mg and 100 mg iron in 100 mL saline) in PP bottles or bags under aseptic conditions. The diluted solutions were stored at 30°C and 75%±5% relative humidity (rH) for 72 h, and samples were withdrawn aseptically at preparation and after 24 h, 48 h and 72 h. Multiple parameters were used to test stability-related measures (pH, total iron and iron (II) content, molecular weight range determination, microbial contamination and particles count ≥10 μm). Overall, Ferinject diluted in 0.9% (w/v) NaCl solution and stored in PP bottles and bags was stable within the specifications for the complex and the acceptability limits set for all assays. In both containers, total iron content remained stable, within 10% of the theoretical iron content, and levels of iron (II) remained far below the threshold of acceptability. All preparations were free from sediments, particle numbers were acceptable and there was no microbial contamination. The molecular weight distribution and polydispersity index were also acceptable. Under the tested experimental conditions, colloidal ferric carboxymaltose solution (Ferinject) diluted in saline in PP infusion bottles or bags demonstrated physical and chemical stability for up to 72 h at 30°C and 75% rH. Because of the lack of additional clinical data, when using ferric carboxymaltose, physicians/pharmacists should refer to the dilution and storing recommendations given in the product's summary of product characteristics.

    We present Goldstone radar imaging of four near-Earth asteroids during Feb-Jun 2017. The signal-to-noise ratios were very strong for each object and we obtained detailed images with range resolutions as fine as 3.75 m/pixel. 2017 BQ6 was discovered on Jan 26 and approached Earth within 6.5 lunar distances on Feb 7. Radar images show that it is a strikingly angular object roughly 200 m in diameter with a rotation period of 3 h. Its multi-faceted shape challenges the expectation that it is a rubble pile. 2017 CS was discovered on Feb 2 and approached within 8 lunar distances on May 29. It appears rounded on large scales but has considerable fine-scale topography evident along its leading edges. The images suggest a diameter of 1 km and a spin period consistent with the 40 h period obtained from photometry by P. Pravec (pers. comm.). The highest resolution images show evidence for meter-size boulders, ridges, and broad concavities. 2007 WV4 was imaged in late May and early June, has a diameter of 900 meters, and appears distinctly angular with at least three large facets > 100 m in extent. Tracking of features in the images gives a rotation period of about 12 hours. 2014 JO25 approached within 4.6 lunar distances on April 19. This was the closest encounter by an asteroid with an absolute magnitude brighter than 18 known in advance until 2027, when 1999 AN10 will approach within one lunar distance. Radar imaging shows that 2014 JO25 is an irregular object, consisting of two components connected by a narrow neck. The asteroid has pole on dimensions of roughly 1 x 0.6 km in the images. Imaging with 3.75 m/pixel resolution places thousands of pixels on the object and reveals ridges, concavities, flat regions up to 200 meters long, and radar-bright spots suggestive of boulders. Tracking of features in the images yields a rotation period of about 4.5 hours that is among the fastest of the 50 known contact binaries in the near-Earth population.

    Permanent modifiers (V, Ir, Ru, V-Ir, V-Ru, and W-V) thermally coated on to platforms of pyrolytic graphite tubes were employed for the determination of Cd, Pb, and Zn in botanic and biological slurries by electrothermal atomic absorption spectrometry (ETAAS). Conventional Pd + Mg(NO 3 ) 2 modifier mixture was also used for the determination of analytes in slurries and digested samples. Optimum masses and mass ratios of permanent modifiers for Cd, Pb, and Zn in slurry sample solutions were investigated. The 280 μg of V, 280 μg of V + 200 μg of Ir, 280 μg of V + 200 μg of Ru or 240 μg of W + 280 μg of V in 0.2% (v/v) Triton X-100 plus 0.5% (v/v) HNO 3 mixture was found as efficient as 5 μg of Pd + 3 μg of Mg(NO 3 ) 2 modifier mixture for obtaining thermal stabilization, and for obtaining best recoveries. Optimization conditions of analytes, such as pyrolysis and atomization temperature, characteristic masses and detection limits, and atomization and background peak profiles were studied with permanent and 5 μg of Pd + 3 μg of Mg(NO 3 ) 2 conventional modifiers and compared with each other. The permanent V-Ir, V-Ru, and W-V modifiers remained stable for approximately 250-300 firings when 20 μl of slurries and digested samples were delivered into the atomizer. In addition, the mixed permanent modifiers increase the tube lifetime by 50-95% when compared with untreated platforms. The characteristic masses and detection limits of analytes (dilution factor of 125 ml g -1 ) obtained with V-Ir based on integrated absorbance as example for 0.8% (m/v) slurries were 1.0 pg and 3 ng g -1 for Cd, 18 pg and 17 ng g -1 for Pb, and 0.7 pg and 4 ng g -1 for Zn, respectively. The results of analytes obtained by employing V-Ir, V-Ru, and W-V permanent modifier mixtures in botanic and biological certified and standard reference materials were in agreement with the certified values of reference materials

    The objective of the study was to determine the effect of fatty acids on CYP enzymes and the effect of BSA on intrinsic clearance of probe substrates. The inhibitory effect of thirteen fatty acids including saturated, mono-unsaturated and polyunsaturated fatty acids on CYP enzymes, kinetic parameters and intrinsic clearance values of nine CYP marker probe substrate reactions in the absence and presence of BSA (0.1 and 1.0% w/v) were characterized in human liver microsomes. The results demonstrate that most of the unsaturated fatty acids showed marked inhibition towards CYP2C8 mediated amodiaquine N-deethylation followed by inhibition of CYP2C9 and CYP2B6 mediated activities. The addition of 0.1% BSA in the incubation markedly improved the unbound intrinsic clearance values of probe substrates by reducing the K m values with little or no effect on maximal velocity. The addition of BSA (0.1 and 1.0% w/v) did not influence the unbound intrinsic clearance of marker reactions for CYP2A6, and CYP3A4 enzymes. The addition of 0.1% w/v BSA is sufficient to determine the intrinsic clearance of marker probe reactions by metabolite formation approach. The predicted hepatic clearance values for the substrates using the well-stirred model, in the presence of BSA (0.1% BSA), are comparable to the in vivo hepatic clearance values.

  1. Using Dust Lines to Learn About Planetary Birthplaces

    Science.gov (United States)

    Kohler, Susanna

    2017-05-01

    Observations of the protoplanetary disks that surround young stars provide crucial information about the initial conditions for planet formation. In a recent study, a team of scientists has proposed a novel new approach for determining disk properties from observations.Limitations to Direct MeasurementArtists impression of a protoplanetary disk surrounding a young star. [ESO/L. Calada]The surface density of protoplanetary disks (i.e., how much mass is there and where is it concentrated?) cant be measured directly, since most of the disk mass is in molecular hydrogen gas, which doesnt readily emit.Instead, disk surface densities are inferred by measuring other components of the disk, like dust or molecules like CO or HD, and then making assumptions about the molecular abundances or the dust-to-gas ratio in the disk. Disk surface density estimatesare therefore heavily dependent upon the assumptions that went into them.Now, a team of scientists led by Diana Powell (University of California Santa Cruz) has proposed a new technique in which observations of adisk in different wavelengths can be used to determine itssurface density profile without the need for such assumptions.Schematic showing disk dust lines for three different particle sizes, s1 s2 s3. Particles of size s1 exist in the yellow region, so in observations at wavelength obs=s1, a disk the size of the yellow region will be seen. Particles of size s2 exist in the yellow and red region, so a disk will extend to the end of the red region for obs=s2. Particles of size s3 exist throughout the disk, so the full disk size will be seen for obs=s3. [Powell et al. 2017]How Does It Work?Particles in a protoplanetary disk collide and stick together, thereby growing over time. But particles are also removed from the outskirts of the disk by a process called drift. More massive particles are removed from closer in to the star, so average particle sizes get smaller the further from the star you move out in a disk. For this reason, the disks radial size appears to be different in different wavelengths: at long wavelengths (i.e., looking at large particles) a disk might only span 50 AU, whereas at smaller wavelengths (looking at small particles) the same disk may span 300 AU. These different outer edges are known as dust lines.The model proposed by Powell and collaborators relies on the idea that at a dust line for a given particle size, the growth timescale and drift timescale for particles of that size are both equal to the age of the disk. Setting these theoretical timescales equal at dust lines and using the age of the disk (expected to be the same as the age of the star, which is measurable) makes it possible to calculatethe surface density profile for the disk. In this way, the profile can be measured without the need for assumptions about abundances or dust-to-gas ratios.Dust surface density calculated by authors for TW Hya (blue points), compared to the dust surface density previously estimated for the system using an assumed dust-to-gas ratio (black line). The authors measurements are systematically lower. [Powell et al. 2017]Testing the ApproachThe team tested their technique on the disk TW Hya, finding a surface density profile thats in agreement with lower limits set from measurements of the HD gas in the disk. Powell and collaborators then describe a series of observational tests of their technique that, when applied to a larger set of protoplanetary disks from future ALMA observations, will hopefully confirm the validity of their approach.If this new method of measuring disk surface density profiles indeed proves successful, it could have an enormous impact on the field, making it much easier to learn about the evolution of protoplanetary disks and the planets forming within them.CitationDiana Powell et al 2017 ApJ 840 93. doi:10.3847/1538-4357/aa6d7c

    Here we introduce a database of calibrated natural images publicly available through an easy-to-use web interface. Using a Nikon D70 digital SLR camera, we acquired about six-megapixel images of Okavango Delta of Botswana, a tropical savanna habitat similar to where the human eye is thought to have evolved. Some sequences of images were captured unsystematically while following a baboon troop, while others were designed to vary a single parameter such as aperture, object distance, time of day or position on the horizon. Images are available in the raw RGB format and in grayscale. Images are also available in units relevant to the physiology of human cone photoreceptors, where pixel values represent the expected number of photoisomerizations per second for cones sensitive to long (L), medium (M) and short (S) wavelengths.

  5. Tracing salmon to their birthplace by activable tracer technique

    International Nuclear Information System (INIS)

    Shibuya, Masao

    1978-01-01

    Activable tracer technique was applied to trace the recurrent migration of white salmons, as a typical example of employing radioactivation analysis to the study of agricultural and marinefields. Europium was adopted because it is easy to use technically with less influence on fish body and easy to detect, and its remaining time is very long. Artificially hatched young white salmons were stocked in the Saibetsu River after being raised for a month with europium-containing feed. These stocked fish were labeled by fin-cutting method. Recurrent salmons (fin cutting-labeled fish) were then collected and dissected. The fishes were divided into otoliths, scales, flesh, internal organs, gills, bones, etc., and irradiated for 5 min in JRR-2 reactor of Japan Atomic Energy Research Institute. Europium was detected from the scales and otoliths of 3 to 4 year stocked adult fishes by γ-spectrometry of Eu. This proved the availability of activable tracer method for tracing the recurrent migration of salmons. (Kobatake, H.)

    Davis, William [West Virginia University Research Corporation, Morgantown, WV (United States)

    2015-09-01

    The scope of this project was changed during the course of the project. Phase I of the project was to construct a site similar to the site at Central West Virginia Regional Airport in Charleston, WV to show that duplication of the site was a feasible method of conducting hydrogen stations. Phase II of the project was necessitated due to a lack of funding that was planned for the development of the station in Morgantown. The US Department of Energy determined that the station in Charleston would be dismantled and moved to Morgantown and reassembled at the Morgantown site. This necessitated storage of the components of the station for almost a year at the NAFTC Headquarters which caused a number of issues with the equipment that will be discussed in later portions of this report. This report will consist of PHASE I and PHASE II with discussions on each of the tasks scheduled for each phase of the project.

    2014-12-01

    The Amazon River starts at the confluence between the Maranon and Ucayali Rivers near Nauta City. The Maranon River is an anabranching channel while the Ucayali River near the confluence is transitioning from purely meandering to anabranching channel. The interaction of water and sediment between these two large rivers is important for the Pacaya-Samiria Peruvian Reserve, a region with one of highest biodiversity in the planet. Past studies related to flow, sediment and morphology at confluences have been performed for single threat channels. Herein a detailed mapping, sediment sampling and hydrodynamics are carried for a confluence between anabranching and meandering channels. Furthermore, remote sensing analysis have been performed to understand that the confluence point has been changing at the geologcal time scale increasing the morphological structures around the Ucamara depression, where the Pacaya-Samiria reserve is located. Results of the field studies indicate complex mixing processes downstream of the confluence, where secondary flows are observed driven the sediment mixing. The dynamic of the confluence point is governed by the evolution of the Ucayali River and the local geology. These findings will help us to relate mixing processes in one of the largest wetlands in the world.

    Some forms of epigenetic abnormalities transmitted to offspring are manifested in differences in disease incidence that depend on parent-of-origin. To explore whether such phenomena might operate in schizophrenia spectrum disorders, we estimated the relative incidence of these conditions in relation to parent-of-origin by considering the two grandfathers' countries of birth. In a prospective cohort of 88,829 offspring, born in Jerusalem in 1964-76 we identified 637 cases through Israel's psychiatric registry. Relative risks (RR) were estimated for paternal and maternal grandfathers' countries of birth using proportional hazards methods, controlling for parents' ages, low social class and duration of marriage. After adjusting for multiple observations, we found no significant differences between descendants of maternal or paternal grandfathers born in Iraq, Iran, Turkey, Syria, Yemen, Morocco, Algeria, Tunisia, Libya/Egypt, Poland, USSR, Czechoslovakia, Germany or the USA. Those with paternal grandfathers from Romania (RR=1.9, 95% CI=1.3-2.8) or Hungary (1.6, 1.0-2.6) showed an increased incidence; however, those with maternal grandfathers from these countries experienced reduced incidence (RR=0.5, 0.3-0.8 and 0.4, 0.2-0.8). In post-hoc analyses we found that results were similar whether the comparison groups were restricted to descendants of other Europeans or included those from Western Asia and North Africa; and effects of paternal grandfathers from Romania/Hungary were more pronounced in females, while effects of maternal grandfathers from these countries were similar in males and females. These post-hoc "hypothesis-generating" findings lead one to question whether some families with ancestors in Romania or Hungary might carry a variant or mutation at a parentally imprinted locus that is altering susceptibility to schizophrenia. Such a locus, if it exists, might involve the X chromosome.

  19. The Journey of Lipoproteins Through the Cell: One Birthplace, Multiple Destinations.

    Science.gov (United States)

    Szewczyk, J; Collet, J-F

    2016-01-01

    Bacterial lipoproteins are a very diverse group of proteins characterized by the presence of an N-terminal lipid moiety that serves as a membrane anchor. Lipoproteins have a wide variety of crucial functions, ranging from envelope biogenesis to stress response. In Gram-negative bacteria, lipoproteins can be targeted to various destinations in the cell, including the periplasmic side of the cytoplasmic or outer membrane, the cell surface or the external milieu. The sorting mechanisms have been studied in detail in Escherichia coli, but exceptions to the rules established in this model bacterium exist in other bacteria. In this chapter, we will present the current knowledge on lipoprotein sorting in the cell. Our particular focus will be on the surface-exposed lipoproteins that appear to be much more common than previously assumed. We will discuss the different targeting strategies, provide numerous examples of surface-exposed lipoproteins and discuss the techniques used to assess their surface exposure. © 2016 Elsevier Ltd All rights reserved.

  5. Stress Relaxation Behavior and Its Prediction of CrMoWV Steel

    2017-05-01

    Full Text Available The stress relaxation data up to 8760h at 550℃ and 600℃of 12Cr-1Mo-1W-0.25V heat-resistant steel were used as the object to study the method of how to accurately and effectively predict long-term relaxation stress by using short-time relaxation data. When relaxation model is used to extrapolate the long-term relaxation stress directly, it is found that the parameters of the relaxation model depend on the length of the fitted data. The time-dependent parameter model, naming as timing parameter method, is proposed to predict the long-term relaxation stress with high accuracy. By comparison of the results of timing parameter method and direct extrapolation method, timing parameter method has obvious advantages in predicting long time relaxation stress with short time relaxation data, as the timing parameter method has a more accurate prediction than that of direct extrapolation method.

    2018-02-01

    the aim of the study was to explore the views and experiences of women, midwives and obstetricians on the intrapartum transfer of women from planned homebirth to hospital in Australia. a Constructivist Grounded Theory approach was taken, to conceptualise the social interactions and processes grounded in the data. urban and regional areas in four states of south-eastern Australia. semi-structured qualitative interviews were conducted with 36 women, midwives and obstetricians who had experienced an intrapartum homebirth transfer within three years prior to the interview. Interviews were audio recorded and transcribed verbatim. women who were transferred to hospital from a planned homebirth made physical and psychological journeys out of their comfort zone, as they faced the uncertainty of changing expectations for their birth. The trusting relationship between a woman and her homebirth midwife was crucial to women's sense of safety and well-being in hospital. Midwives and obstetricians, when congregating in the hospital birthing rooms of transferred women, also felt out of their comfort zones. This was due to the challenges of converging with others who possessed conflicting paradigms of safety and risk in birth that were at odds with their own, and adapting to different routines, roles and responsibilities. These differences were derived from diverse professional, social and personal influences and often manifested in stereotyping behaviours and 'us and them' dynamics. When midwife-woman partnerships were respected as an inclusive part of women's care, collaboration ensued, conflict was ameliorated, and smooth transfers could be celebrated as successes of the maternity care system. supporting woman centred care in homebirth transfers means acknowledging the social challenges of collaborating in the unique context of a transferred woman's hospital birthing room. Understanding the power of the midwife-woman partnership, and its value to the health and well-being of each woman and her baby, is key to facilitating a successful transfer. the midwife-woman partnership played a central role in providing the necessary support and advocacy for women transferred out of their comfort zone. When midwives worked together in an integrated system to provide the necessary care and support for women who were transferred, greater levels of collaboration emerged and women's perceptions of their quality of care was high. In practice, this meant health professionals respecting each other's roles, responsibilities and expertise, and ameliorating 'us and them' dynamics. Copyright © 2017 Elsevier Ltd.

    In 1998, three groups of cattle at three locations in Lousiana were treated with Dectomax((R)) (0.5% doramectin) Pour-On and horn fly populations were monitored. Acceptable levels (less than 50 flies per side) of horn fly control were observed from 4 to 8 weeks. Differences in the length of control among the three sites were most likely affected by immigration of adult flies from untreated groups. In 1999, acceptable horn fly control was obtained for 13 weeks by the use of two treatments of doramectin Pour-On.

    Objectives To evaluate the impact of maternal BMI on intrapartum interventions and adverse outcomes that may influence choice of planned birth setting in healthy women without additional risk factors. Design Prospective cohort study. Setting Stratified random sample of English obstetric units. Sample 17 230 women without medical or obstetric risk factors other than obesity. Methods Multivariable log Poisson regression was used to evaluate the effect of BMI on risk of intrapartum interventions and adverse maternal and perinatal outcomes adjusted for maternal characteristics. Main outcome measures Maternal intervention or adverse outcomes requiring obstetric care (composite of: augmentation, instrumental delivery, intrapartum caesarean section, general anaesthesia, blood transfusion, 3rd/4th degree perineal tear); neonatal unit admission or perinatal death. Results In otherwise healthy women, obesity was associated with an increased risk of augmentation, intrapartum caesarean section and some adverse maternal outcomes but when interventions and outcomes requiring obstetric care were considered together, the magnitude of the increased risk was modest (adjusted RR 1.12, 95% CI 1.02–1.23, for BMI > 35 kg/m2 relative to low risk women of normal weight). Nulliparous low risk women of normal weight had higher absolute risks and were more likely to require obstetric intervention or care than otherwise healthy multiparous women with BMI > 35 kg/m2 (maternal composite outcome: 53% versus 21%). The perinatal composite outcome exhibited a similar pattern. Conclusions Otherwise healthy multiparous obese women may have lower intrapartum risks than previously appreciated. BMI should be considered in conjunction with parity when assessing the potential risks associated with birth in non-obstetric unit settings. PMID:24034832

  19. Duration and urgency of transfer in births planned at home and in freestanding midwifery units in England: secondary analysis of the Birthplace national prospective cohort study

    2013-01-01

    Background In England, there is a policy of offering healthy women with straightforward pregnancies a choice of birth setting. Options may include home or a freestanding midwifery unit (FMU). Transfer rates from these settings are around 20%, and higher for nulliparous women. The duration of transfer is of interest because of the potential for delay in access to specialist care and is also of concern to women. We aimed to estimate the duration of transfer in births planned at home and in FMUs and explore the effects of distance and urgency on duration. Methods This was a secondary analysis of data collected in a national prospective cohort study including 27,842 ‘low risk’ women with singleton, term, ‘booked’ pregnancies, planning birth in FMUs or at home in England from April 2008 to April 2010. We described transfer duration using the median and interquartile range, for all transfers and those for reasons defined as potentially urgent or non-urgent, and used cumulative distribution curves to compare transfer duration by urgency. We explored the effect of distance for transfers from FMUs and described outcomes in women giving birth within 60 minutes of transfer. Results The median overall transfer time, from decision to transfer to first OU assessment, was shorter in transfers from home compared with transfers from FMUs (49 vs 60 minutes; p < 0.001). The median duration of transfers before birth for potentially urgent reasons (home 42 minutes, FMU 50 minutes) was 8–10 minutes shorter compared with transfers for non-urgent reasons. In transfers for potentially urgent reasons, the median overall transfer time from FMUs within 20 km of an OU was 47 minutes, increasing to 55 minutes from FMUs 20-40 km away and 61 minutes in more remote FMUs. In women who gave birth within 60 minutes after transfer, adverse neonatal outcomes occurred in 1-2% of transfers. Conclusions Transfers from home or FMU commonly take up to 60 minutes from decision to transfer, to first assessment in an OU, even for transfers for potentially urgent reasons. Most transfers are not urgent and emergencies and adverse outcomes are uncommon, but urgent transfer is more likely for nulliparous women. PMID:24314134

    A non-recombinant mutant of Escherichia coli B, strain SZ194, was developed that produces over 1 M D-lactate from glucose (or sucrose) in 72 h using mineral salts medium supplemented with 1 mM: betaine in simple anaerobic fermentations. Rates and yields were highest at pH 7.5. Yields approached the theoretical maximum with only trace amounts of co-products. Chiral purity of D-lactate was estimated to be 95%. Specific and volumetric productivities for SZ194 in mineral salts medium (pH 7.5) with betaine were equivalent to those in Luria broth.

    Impedance spectroscopy has been used for the measurement of the glass transition of a 10 % maltodextrin solution contained within a glass vial, with externally attached electrodes. Features of the pseudo-relaxation process, associated with the composite impedance of the glass vial-solution assembly, were characterised by the peak amplitude, C(peak)(″), and peak frequency, f(peak), of the capacitance spectra and the equivalent circuit elements that model the impedance spectra (i.e. the solution resistance and solution capacitance) and monitored every 3 min during re-heating of the solution. The time derivatives of all four parameters studied provided a glass transition in close agreement with DSC measurements (-17 °C) and at a precision of ± 0.5 °C. The temperature dependencies of the solution resistance and peak frequency were then characterised with the Arrhenius and Vogel-Fulcher-Tammann fit functions, at temperatures below and above Tg, respectively. The energy of activation (below Tg) was estimated at ~20 kJ mol(-1), and the fragility index (If) of the glass forming liquid (above Tg) was estimated at 0.9. The significance of the fragility index to the development, optimisation and control of the freeze-drying cycle is highlighted. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available The presence and distribution of the TSWV, weeds and thrip vectors in major tomato producing areas in the Andean department of Cundinamarca (Oriente, Sumapaz and Ubate provinces were assessed with the DAS ELISA technique, evaluating the presence of the TSWV in tomato tissue, associated thrips and weeds. High incidences were observed in different provinces of the Andean department of Cundinamarca. The average viral incidence reached 23.3% in Sumapaz, 19.4% in Oriente and 4% in Ubate. The symptoms observed were: brown spots and concentric rings in the leaf area, stems and fruits; browning and spotting in the flower; and wilting in the leaves, stems and flowers. The thrip species with the highest presence were Frankliniella occidentalis, followed by Thrips palmi and Thrips tabaci. We determined the important role of weeds as inoculum sources and vector reservoirs for the species Emilia sonchifolia and Amaranthus dubius

    ARIES (Autonomous Robotic Inspection Experimental System) is a semi-autonomous robotic system intended for use in the automatic inspection of stored containers of low level nuclear waste. The project is being performed by a team under the SCUREF (South Carolina University Research and Education Foundation) comprised of the University of South Carolina, and Clemson University, and their industrial partner Cybermotion Inc., with funding from METC, Morgantown, WV. The ARIES program is unusual in the level of cooperation between the universities and Cybermotion. By maintaining daily communications via telephone and E-Mall, participating in frequent meetings with each other and the end users, and by developing an open flow of (sometimes sensitive) technical information, the team has been able to build on a very broad base of intellectual strengths and existing technology without wasteful duplication. This base includes all of the navigation and control software and hardware developed by Cybermotion over nearly a decade and the deep technology resources of the university partners. It is anticipated that the result will be a technically advanced system that is much closer to a deployable configuration than is typical for this stage of research. In this decade of shrinking budgets, such relationships can provide a crucial advantage for all participants

    The program entails nondestructive testing, failure analysis, and studies of erosive wear, corrosion, and refractory degradation. Analysis of recent refractory-slag interaction tests suggests that as the chromia content is increased from 10 to 32%, the primary reaction product changes from calcium hexaluminate to spinel, significantly increasing the corrosion resistance of the refractory. Field reliability of the high-temperature ultrasonic erosion scanner was demonstrated at both a coal liquefaction plant (SRC at Tacoma, WA) and a coal gasification plant (Morgantown, WV). Continuous high-temperature operation has been demonstrated and an accuracy of +-0.025 mm seems achievable. Equipment has been ordered for field tests of passive acoustic systems at Exxon. This includes a four-channel tape recorder, differential amplifiers, and signal conditioners. Corrosion studies have been completed on effects of multicomponent gas environments on corrosion mechanisms and uniaxial tensile properties of Fe-Ni-Cr alloys. Results of these and other tests utilizing 10,000-h exposures suggest that corrosion rates of 0.6 mm/y can be expected. Failure analysis activities included studies of compressor diaphragms from the Grand Forks Energy Technology Center coal-liquefaction continuous-process unit. Cracks were found in two of the three diaphragms. Failure of an internal solids transfer line from HYGAS appears to have been caused by severe localized sulfidation of the high-nickel Inconel 182 weld metal used to fabricate the line.

Many influences exist during the teen years including transitions (eg, puberty that affect one’s body shape, weight status, and appearance. Weight status exists along a spectrum between being obese (ie, where one’s body weight is in the 95th percentile for age and gender to being underweight. Salient influences on body image include the media, which can target adolescents, and peers who help shape beliefs about the perceived body ideal. Internalization of and pressures to conform to these socially prescribed body ideals help to explain associations between weight status and body image. The concepts of fat talk and weight-related bullying during adolescence greatly contribute to an overemphasis on body weight and appearance as well as the development of negative body perceptions and dissatisfaction surrounding specific body parts. This article provides an overview of the significance of adolescent development in shaping body image, the relationship between body image and adolescent weight status, and the consequences of having a negative body image during adolescence (ie, disordered eating, eating disorders, and dysfunctional exercise. Practical implications for promoting a healthy weight status and positive body image among adolescents will be discussed.

Perfluorooctanoic acid (PFOA and perfluorooctane sulfonate (PFOS are perfluoroalkyl chemicals (PFCs used in the manufacture of common consumer products and detected in the blood of the majority of Americans. Emerging biological data suggest that PFC exposure may have a role in the development of hypertension. However, the association between PFCs and hypertension has not yet been explored in humans. Therefore, we examined this association in a representative sample of US children.Methods: A cross-sectional study was performed on 1,655 children from the National Health and Nutrition Examination Survey, 1999–2000 and 2003–2008. The main outcome of interest was hypertension, defined as age, height, and sex specific systolic and/or diastolic blood pressure level at the 95th percentile.Results: We found no association between serum levels of PFOA and PFOS and hypertension in either unadjusted or multivariable-adjusted analyses controlling for age, sex, race-ethnicity, body mass index, annual household income, moderate activity, total serum cholesterol, and serum cotinine. Compared with the lowest quartile, the multivariable-adjusted odds ratio (95% confidence interval of hypertension in the highest quartile of exposure was 0.69 (0.41–1.17 for PFOA and 0.77 (0.37–1.61 for PFOS (all P-trend values >0.30.Conclusion: Our findings indicate that exposure to PFOA or PFOS is not significantly associated with hypertension in children at the lower PFC exposure levels typical of the general population.Keywords: perfluorooctanoic acid, perfluorooctane

    Full Text Available Andrea L Armstead,1,2 Bingyun Li1–3 1Department of Orthopaedics, School of Medicine, 2School of Pharmacy, West Virginia University, 3Mary Babb Randolph Cancer Center, Morgantown, WV, USA Abstract: As the number of commercial and consumer products containing engineered nanomaterials (ENMs continually rises, the increased use and production of these ENMs presents an important toxicological concern. Although ENMs offer a number of advantages over traditional materials, their extremely small size and associated characteristics may also greatly enhance their toxic potentials. ENM exposure can occur in various consumer and industrial settings through inhalation, ingestion, or dermal routes. Although the importance of accurate ENM characterization, effective dosage metrics, and selection of appropriate cell or animal-based models are universally agreed upon as important factors in ENM research, at present, there is no “standardized” approach used to assess ENM toxicity in the research community. Of particular interest is occupational exposure to tungsten carbide cobalt (WC-Co “dusts,” composed of nano- and micro-sized particles, in hard metal manufacturing facilities and mining and drilling industries. Inhalation of WC-Co dust is known to cause “hard metal lung disease” and an increased risk of lung cancer; however, the mechanisms underlying WC-Co toxicity, the inflammatory disease state and progression to cancer are poorly understood. Herein, a discussion of ENM toxicity is followed by a review of the known literature regarding the effects of WC-Co particle exposure. The risk of WC-Co exposure in occupational settings and the updates of in vitro and in vivo studies of both micro- and nano-WC-Co particles are discussed.

In addition, the potential inflammatory effects resulting from pulmonary NP exposure are emerging as an important aspect of nanotoxicity. In this study, the toxicity and inflammatory state resulting from tungsten carbide–cobalt (WC–Co NP exposure in macrophages and a coculture (CC of lung epithelial cells (BEAS-2B and macrophages (THP-1 at a 3:1 ratio were examined. It was found that the toxicity of nano-WC–Co was cell dependent; significantly less toxicity was observed in THP-1 cells compared to BEAS-2B cells. It was demonstrated that nano-WC–Co caused reduced toxicity in the CC model compared to lung epithelial cell monoculture, which suggested that macrophages may play a protective role against nano-WC–Co-mediated toxicity in CCs. Nano-WC–Co exposure in macrophages resulted in increased levels of interleukin (IL-1β and IL-12 secretion and decreased levels of tumor necrosis factor alpha (TNFα. In addition, the polarizing effects of nano-WC–Co exposure toward the M1 (pro-inflammatory and M2 (anti-inflammatory macrophage phenotypes were investigated. The results of this study indicated that nano-WC–Co exposure stimulated the M1 phenotype, marked by high expression of CD40 M1 macrophage surface markers.

Despite the significant advances, challenges remain on which combination strategies will provide the optimal response for any given patient. Defining optimal combination strategies and corresponding companion diagnostics, that will guide clinical decisions are required to target relapsed or refractory multiple myeloma (RRMM in order to improve disease progression, survival and quality of life for patients with MM. Elotuzumab is a humanized monoclonal antibody that targets signaling lymphocytic activation molecule F7 (SLAMF7, approved by the US Food and Drug Administration (FDA in 2015 and the European Medicines Agency in 2016 for the treatment of MM. SLAMF7 is expressed in normal and malignant plasma cells and has lower expression on natural killer (NK cells. Experimental evidence indicates that elotuzumab exhibits anti-myeloma activity through 1 antibody-dependent cell-mediated cytotoxicity, 2 enhancing NK cells cytotoxicity and 3 interfering with adhesion of MM cells to bone marrow stem cells (BMSCs. Although elotuzumab has no single agent activity in patients with RRMM who have received one to three prior therapies, the combination of elotuzumab with anti-myeloma agents, such as immunomodulatory drugs-lenalidomide, or proteasome inhibitors (PIs-bortezomib, remarkably improved the overall response rates and progression-free survival in MM patients with only minimal incremental toxicity. In brief, the clinical data for elotuzumab indicate that targeting SLAMF7 in combination with the use of conventional therapies is feasible and

While device-related complications have been well described, inflammatory reactions to the components of these devices remain underreported. In contrast, hypersensitivity reactions associated with other implanted therapies, such as endovascular and cardiac rhythm devices, have been detailed. The purpose of this case series is to describe the clinical presentation and course of inflammatory reactions as well as the histology of these reactions. All patients required removal of the entire device after developing inflammatory reactions over a time course of 1–3 months. Two patients developed a foreign body reaction in the lead insertion wound as well as at the implantable pulse generator site, with histology positive for giant cells. One patient developed an inflammatory dermatitis on the flank and abdomen that resolved with topical hydrocortisone. “In vivo” testing with a lead extension fragment placed in the buttock resulted in a negative reaction followed by successful reimplantation of an SCS device. Inflammatory reactions to SCS devices can manifest as contact dermatitis, granuloma formation, or foreign body reactions with giant cell formation. Tissue diagnosis is essential, and

    Three experiments examined the influence of ultraviolet-B radiation (UV-B; 280-320 nm) exposure on reproduction in Brassica rapa (Brassicacaeae). Plants were grown in a greenhouse under three biologically effective UV-B levels that stimulated either an ambient stratospheric ozone level (control), 16% ({open_quotes}low enhanced{close_quotes}), or 32% ({open_quotes}high enhanced{close_quotes}) ozone depletion levels at Morgantown, WV, USA in mid-March. In the first experiment,pollen production and viability per flower were reduced by {approx}50% under both enhanced UV-B levels relative to ambient controls. While plants under high-enhanced UV-B produced over 40% more flowers than plants under the two lower UV-B treatments, whole-plant production of viable pollen was reduced under low-enhanced UV-B to 34% of ambient controls. In the second experiment, the influence of source-plant UV-B exposure on in vitro pollen from plants was examined and whether source-plant UV-B exposure influenced in vitro pollen germination and viability. Pollen from plants under both enhanced-UV-B was reduced from 65 to 18%. Viability of the pollen from plants grown under both enhanced UV-B treatments was reduced to a much lesser extent: only from {approx}43 to 22%. Thus, ambient source-plant pollen was more sensitive to enhanced UV-B levels to fertilize plants growing under ambient-UV-B levels, and assessed subsequent seed production and germination. Seed abortion rates were higher in plants pollinated with pollen from the enhanced UV-B treatments, than from ambient UV-B. Despite this, seed yield (number and mass) per plant was similar, regardless of the UV-B exposure of their pollen source. Our findings demonstrate that enhanced UV-B levels associated with springtime ozone depletion events have the capacity to substantially reduce viable pollen production, and could ultimately reduce reproductive success of B. rapa. 37 refs., 4 figs., 2 tabs.

Methods: We used a retrospective longitudinal panel data design. Data were extracted for multiple years (2002–2009 of the Medicare Current Beneficiary Survey (MCBS linked with fee-for-service Medicare claims. Generic and brand names of inhaled anticholinergics were used to identify inhaled anticholinergic utilization from the self-reported prescription medication files. All-cause mortality was assessed using the vital status variable. Unadjusted group differences in mortality rates were tested using the chi-square statistic. Multivariable logistic regressions with independent variables entered in separate blocks were used to analyze the association between inhaled anticholinergic use and all-cause mortality. All analyses accounted for the complex design of the MCBS. Results: Overall, 19.4% of the elderly Medicare beneficiaries used inhaled anticholinergics. Inhaled anticholinergic use was significantly higher (28.5% among those who reported poor health compared with those reporting excellent or very good health (12.7%. Bivariate analyses indicated that inhaled anticholinergic use was associated with significantly higher rates of all-cause mortality (18.7% compared with nonusers (13.6%. However

  4. Effect of enhanced UV-B radiation on pollen quantity, quality, and seed yield in Brassica rapa (Brassicaceae)

    Three experiments examined the influence of ultraviolet-B radiation (UV-B; 280-320 nm) exposure on reproduction in Brassica rapa (Brassicacaeae). Plants were grown in a greenhouse under three biologically effective UV-B levels that stimulated either an ambient stratospheric ozone level (control), 16% (open-quotes low enhancedclose quotes), or 32% (open-quotes high enhancedclose quotes) ozone depletion levels at Morgantown, WV, USA in mid-March. In the first experiment,pollen production and viability per flower were reduced by ∼50% under both enhanced UV-B levels relative to ambient controls. While plants under high-enhanced UV-B produced over 40% more flowers than plants under the two lower UV-B treatments, whole-plant production of viable pollen was reduced under low-enhanced UV-B to 34% of ambient controls. In the second experiment, the influence of source-plant UV-B exposure on in vitro pollen from plants was examined and whether source-plant UV-B exposure influenced in vitro pollen germination and viability. Pollen from plants under both enhanced-UV-B was reduced from 65 to 18%. Viability of the pollen from plants grown under both enhanced UV-B treatments was reduced to a much lesser extent: only from ∼43 to 22%. Thus, ambient source-plant pollen was more sensitive to enhanced UV-B levels to fertilize plants growing under ambient-UV-B levels, and assessed subsequent seed production and germination. Seed abortion rates were higher in plants pollinated with pollen from the enhanced UV-B treatments, than from ambient UV-B. Despite this, seed yield (number and mass) per plant was similar, regardless of the UV-B exposure of their pollen source. Our findings demonstrate that enhanced UV-B levels associated with springtime ozone depletion events have the capacity to substantially reduce viable pollen production, and could ultimately reduce reproductive success of B. rapa. 37 refs., 4 figs., 2 tabs

Methods: This was a randomized, multicenter, double-masked, three-month, three-arm contribution-of-elements study with a three-month safety extension. Patients were randomly assigned 1:1:1 to treatment with BBFC, brinzolamide 1%, or brimonidine 0.2% after a washout period. Patients dosed their study medications three times daily at 8 am, 3 pm, and 10 pm for six months. Patients returned for visits at two weeks, six weeks, three months, and six months. IOP measurements were used to assess efficacy. Safety assessments were adverse events, corrected distance visual acuity, slit-lamp biomicroscopy, pachymetry, perimetry, fundus parameters, and cardiac parameters. Results: A total of 690 patients were randomized. Six-month mean IOP values were similar to those at three months, when the mean IOP in patients treated with BBFC was significantly lower than that of either monotherapy group. A total of 175 patients experienced at least one treatment-related adverse event (BBFC, 33.0%; brinzolamide, 18.8%; brimonidine, 24.7%, eight of which were severe, and five resulted in discontinuation. Seventy-seven patients discontinued participation due to treatment-related adverse events (BBFC, 17.2%; brinzolamide, 2.1%; brimonidine, 14.5%.

Methods: This study utilized a cross-sectional, retrospective study design, using data from multiple years (2006-2009 of the Medicare Current Beneficiary Survey linked with fee-for-service Medicare claims. Presence of COPD and GERD was identified using diagnoses codes. Health care expenditures consisted of inpatient, outpatient, prescription drugs, dental, medical provider, and other services. For the analysis, t-tests were used to examine unadjusted subgroup differences in average health care expenditures by the presence of GERD. Ordinary least squares regressions on log-transformed health care expenditures were conducted to estimate the excess health care expenditures associated with GERD. The Blinder-Oaxaca linear decomposition technique was used to determine the contribution of predisposing characteristics, enabling resources, need variables, personal health care practices, and external environment factors, to excess health care expenditures associated with GERD. Results: Among elderly Medicare beneficiaries with COPD, 29.3% had co-occurring GERD. Elderly Medicare beneficiaries with COPD/GERD had 1.5 times higher ($36,793 vs $24,722 [P<0.001] expenditures than did those with COPD/no GERD. Ordinary

    Full Text Available To test the Hispanic and Immigrant Paradoxes—i.e., survival advantages despite a worse risk factor profile—and the modifying role of neighborhood context, we examined associations between patient ethnicity, birthplace, neighborhood Hispanic density and neighborhood poverty among 166,254 female breast cancer patients diagnosed 1995–2009 in Texas, U.S. Of all, 79.9% were non-Hispanic White, 15.8% Hispanic U.S.-born, and 4.2% Hispanic foreign-born. We imputed birthplace for the 60.7% of Hispanics missing birthplace data using multiple imputation. Shared frailty Cox proportional hazard models (patients nested within census tracts adjusted for age, diagnosis year, stage, grade, histology, urban/rural residence, and local mammography capacity. Whites (vs. U.S.-born Hispanics had increased all-cause and breast cancer mortality. Foreign-born (vs. U.S.-born Hispanics had increased all-cause and breast cancer mortality. Living in higher Hispanic density neighborhoods was generally associated with increased mortality, although associations differed slightly in magnitude and significance by ethnicity, birthplace, and neighborhood poverty. We found no evidence of an Immigrant Paradox and some evidence of a Hispanic Paradox where protective effects were limited to U.S.-born Hispanics. Contrary to prior studies, foreign birthplace and residence in higher Hispanic density neighborhoods were associated with increased mortality. More research on intersections between ethnicity, birthplace and neighborhood context are needed.

    SRI and RTI to conduct tests at high-temperature, high-pressure conditions (HTHP). The HTHP tests confirmed the ability of nahcolite pellets and granules to reduce the HCl vapor levels to less than 1 ppm levels with a very high sorbent utilization for chloride capture. The effect of several operating variables such as temperature, pressure, presence of hydrogen sulfide, and sorbent preparation methods was studied on the efficacy of HCl removal by the sorbent. Pilot-scale tests were performed in the fluidized-bed mode at the gasifier facility at the GE-CRD. Sorbent exposure tests were also conducted using a hot coal gas stream from the DOE/FETC's fluidized-bed gasifier at Morgantown, WV. These tests confirmed the results obtained at SRI and RTI. A preliminary economic assessment showed that the cost of HCl removal in a commercial IGCC system will be about $0.001/kWh (1 mills/kWh).

    The characteristics of marriages contracted in 1993 in two districts of the city of Khar'kov were studied. The age, education, occupation, ethnicity, and birthplace of the spouses were recorded. The genetic demographic parameters of the marriage structure were compared to the results of a similar study performed in 1985. It was found that since 1985, the average age of marriage and the educational level of spouses had increased, while the ethnic diversity and coefficients of contingency by the spouses' ethnicity and profession had decreased. The contingency coefficient for the birthplace has increased. The causes and genetic consequences of these changes are discussed.

    As with much of Europe, the Netherlands has no explicit ‘race’ discourse; however, the state, through its public policy and administrative practices, does categorise its population along ‘ethnic’ lines, using birthplace — one's own or one's (grand-) parent's — as the surrogate determining factor.

    Full Text Available Water vapor (WV has a vital effect on global climate change. Using satellite data observed by AURA/MLS and ERA-Interim reanalysis datasets, the spatial distributions and temporal variations of WV were analyzed. It was found that high WV content in the UTLS over the southern Tibetan Plateau is more apparent in summer, due to monsoon-induced strong upward motions. The WV content showed the opposite distribution at 100 hPa, though, during spring and winter. And a different distribution at 121 hPa indicated that the difference in WV content between the northern and southern plateau occurs between 121 and 100 hPa in spring and between 147 and 121 hPa in winter. In the UTLS, it diminishes rapidly with increase in altitude in these two seasons, and it shows a “V” structure in winter. There has been a weak increasing trend in WV at 100 hPa, but a downtrend at 147 and 215 hPa, during the past 12 years. At the latter two heights, the WV content in summer has been much higher than in other seasons. Furthermore, WV variation showed a rough wave structure in spring and autumn at 215 hPa. The variation of WV over the Tibetan Plateau is helpful in understanding the stratosphere-troposphere exchange (STE and climate change.

    2012-01-01

    To evaluate image quality of 320-detector row wide-volume (WV) computed tomography (CT) compared to 64-detector row helical CT from axial images and coronal multiplanar reformation (MPR). Thirty-five patients with diffuse lung diseases were scanned using both 320-detector row WV CT (coneXact and volumeXact+) and 64-detector row helical protocols. Three blinded observers evaluated dislocation and heterogeneity of normal structures on 3 MPR patterns (WV scan with coneXact, WV scan with volumeXact+, and helical scan) using a 3-point scale from 1 (severe dislocation/heterogeneity) to 3 (no dislocation/heterogeneity). They also evaluated axial images of 2 scan patterns (WV with volumeXact+ and helical) using a 5-point scale from 1 (nondiagnostic) to 5 (excellent). Statistical analyses were performed with a post hoc test, Wilcoxon signed rank test, Mann-Whitney U test, or the Kendall W test. The WV scans with the coneXact algorithm had significantly lower quality scores than the WV scans with the volumeXact+ algorithm and the helical scans (P < 0.01) with MPR. Helical scans had significantly lower quality scores than the WV scans with volumeXact+ for heterogeneity on the mediastinal window setting with MPR (P < 0.01). There were no significant differences concerning total image quality of axial images between the WV scans with the volumeXact+ algorithm and the helical scans. The overall image quality of WV scans with the volumeXact+ algorithm was almost comparable to that of the helical scans on the lung window setting, but density homogeneity with helical scans was inferior to that of the WV scans with the volumeXact+ algorithm on the mediastinal window setting with MPR.

  18. Direct Coal -to-Liquids (CTL) for Jet Fuel Using Biomass-Derived Solvents

    Energy Technology Data Exchange (ETDEWEB)

    Chauhan, Satya P. [Battelle, Columbus, OH (United States); Garbark, Daniel B. [Battelle, Columbus, OH (United States); Taha, Rachid [Battelle, Columbus, OH (United States); Peterson, Rick [Battelle, Columbus, OH (United States)

    2017-09-30

    Battelle has demonstrated a novel and potentially breakthrough technology for a direct coal-to-liquids (CTL) process for producing jet fuel using biomass-derived coal solvents (bio-solvents). The Battelle process offers a significant reduction in capital and operating costs and a substantial reduction in greenhouse gas (GHG) emissions, without requiring carbon capture and storage (CCS). The results of the project are the advancement of three steps of the hybrid coal/biomass-to-jet fuel process to the technology readiness level (TRL) of 5. The project objectives were achieved over two phases. In Phase 1, all three major process steps were explored and refined at bench-scale, including: (1) biomass conversion to high hydrogen-donor bio-solvent; (2) coal dissolution in biomass-derived bio-solvent, without requiring molecular H2, to produce a synthetic crude (syncrude); and (3) two-stage catalytic hydrotreating/hydrogenation of syncrude to jet fuel and other distillates. In Phase 2, all three subsystems of the CTL process were scaled up to a pre-pilot scale, and an economic analysis was carried out. A total of over 40 bio-solvents were identified and prepared. The most unique attribute of Battelle’s bio-solvents is their ability to provide much-needed hydrogen to liquefy coal and thus increase its hydrogen content so much that the resulting syncrude is liquid at room temperature. Based on the laboratory-scale testing with bituminous coals from Ohio and West Virginia, a total of 12 novel bio-solvent met the goal of greater than 80% coal solubility, with 8 bio-solvents being as good as or better than a well-known but expensive hydrogen-donor solvent, tetralin. The Battelle CTL process was then scaled up to 1 ton/day (1TPD) at a pre-pilot facility operated in Morgantown, WV. These tests were conducted, in part, to produce enough material for syncrude-upgrading testing. To convert the Battelle-CTL syncrude into a form suitable as a blending stock for jet

  7. Environmental audit: Fossil energy sites in Wyoming

    International Nuclear Information System (INIS)

    1992-08-01

    This report documents the results of the Comprehensive Baseline Environmental Audit completed for Selected Fossil Energy Sites in Wyoming. During this Audit, facilities, field sites, and activities were investigated and inspected in several areas of Wyoming that are considered to be representative of offsite work falling under the purview of the Morgantown Energy Technology Center (METC) in Morgantown, West Virginia. Department of Energy (DOE) personnel at METC and at the Liquid Fuels Technology Branch (LFTB) in Laramie, Wyoming were interviewed as were DOE contractors and Federal and state regulators. Extensive document review was also a key part of this Audit. The on-site portion of the Audit occurred in Morgantown from May 18 to 22, 1992, and throughout Wyoming from May 26 through June 10, 1992. EH-24 carries out independent assessments of DOE facilities and DOE-funded off-site activities as part of the Assistant Secretary's Environmental Audit Program. That program is designed to evaluate the status of facilities and activities regarding compliance with environmental laws, regulations, DOE Directives, formal written procedures, compliance agreements, and Best Management Practices (BMPs). This internal oversight function plays an important role in improving the compliance status of DOE operations. The Audit stresses the fact that it is the responsibility of line management to conduct operations in an environmentally sound and safe manner. The scope of this Environmental Audit was comprehensive, covering all areas of environmental activities and waste management operations with the exception of the National Environmental Policy Act (NEPA), which is beyond the purview of EH-24. Specifically included within this Audit were Air, Soils/Sediment/Biota, Surface Water/Drinking Water, Groundwater, Waste Management, Toxic and Chemical Materials, Quality Assurance, Radiation, Inactive Waste Sites, and Environmental Management

    The effects of bioleaching on sewage sludge pyrolysis were studied. Sewage sludge was treated by bioleaching with solid concentrations of 6% (w/v), 8% (w/v), 10% (w/v). Results showed that bioleaching treatment could modify the physicochemical properties of sewage sludge and enhance the metals removal. The optimum removal efficiencies of heavy metals were achieved with solid concentration of 6% (w/v) bioleaching treatment: Cu, 73.08%; Zn, 78.67%; Pb, 24.65%; Cd, 79.46%. The characterization results of thermogravimetric analysis (TGA) showed that the bioleached sewage sludge with a 6% (w/v) solid concentration treatment was the easiest to decompose. Pyrolytic experiments of bioleached sewage sludge were performed in a laboratory-scale fixed bed reactor. Results indicated that bioleaching treatment greatly influenced the product yields and gas composition. Copyright © 2015 Elsevier Ltd. All rights reserved.

    This study examines the predictors of birth outcomes among women of European and African ancestry and considers the birthplace of the babies' fathers (foreign born vs. native born) as a protective factor. This is a secondary data analysis of 146,431 singleton births among women of European and African ancestry, both native-born and foreign-born, in a 21 birth hospital region of Central New York State from 1996 to 2003. Foreign born fathers were found to have 15% fewer low birth weight infants than US-born fathers, after controlling for the race and birthplace of the mother, tobacco use and Medicaid. Although this secondary data analysis does not allow us to determine the social determinants of the better birth outcomes among infants of foreign born fathers, it does demonstrate that fathers matter and that foreign born fathers are associated with reduced low birth weight in their infants.

    Background. Urban birth, a risk factor for schizophrenia, is more frequent among second-generation immigrants. The aim of the current study was to determine whether the increased risk for schizophrenia found in second-generation immigrants is explained by the degree of urbanization of birthplace...... and/or factors related to parentage, such as geographic origin or history of residence abroad during upbringing.Method. Using data from the Danish Civil Registration System (CRS), we established a population-based cohort of 2.0 million Danes (persons born in Denmark). Schizophrenia in cohort members...... for urbanization of birthplace and parental characteristics reduced these risks slightly. However, urbanization had a lesser effect in second-generation immigrants than in Danes. History of residence abroad was a risk factor for schizophrenia, regardless of whether parents were foreign-born or native Danes...

    Highlights: • Screening of 50,000 compounds and subsequent lead optimization identified WV970. • WV970 has antiviral effects against influenza A, B and highly pathogenic viral strains. • WV970 inhibits viral genome replication and transcription. • A target database search suggests that WV970 may bind to a number of kinases. • KINOMEscan screening revealed that WV970 has inhibitory effects on 15 kinases. - Abstract: Neuraminidase inhibitors are the only currently available influenza treatment, although resistant viruses to these drugs have already been reported. Thus, new antiviral drugs with novel mechanisms of action are urgently required. In this study, we identified a novel antiviral compound, WV970, through cell-based screening of a 50,000 compound library and subsequent lead optimization. This compound exhibited potent antiviral activity with nanomolar IC{sub 50} values against both influenza A and B viruses but not non-influenza RNA viruses. Time-of-addition and indirect immunofluorescence assays indicated that WV970 acted at an early stage of the influenza life cycle, but likely after nuclear entry of viral ribonucleoprotein (vRNP). Further analyses of viral RNA expression and viral polymerase activity indicated that WV970 inhibited vRNP-mediated viral genome replication and transcription. Finally, structure-based virtual screening and comprehensive human kinome screening were used to demonstrate that WV970 acts as a multiple kinase inhibitor, many of which are associated with influenza virus replication. Collectively, these results strongly suggest that WV970 is a promising anti-influenza drug candidate and that several kinases associated with viral replication are promising drug targets.

    Studies on the assessment of heart rate variability threshold (HRVT) during walking are scarce. We determined the reliability and validity of HRVT assessment during the incremental shuttle walk test (ISWT) in healthy subjects. Thirty-one participants aged 57 ± 9 years (17 females) performed 3 ISWTs. During the 1st and 2nd ISWTs, instantaneous heart rate variability was calculated every 30 s and HRVT was measured. Walking velocity at HRVT in these tests (WV-HRVT1 and WV-HRVT2) was registered. During the 3rd ISWT, physiological responses were assessed. The ventilatory equivalents were used to determine ventilatory threshold (VT) and the WV at VT (WV-VT) was recorded. The difference between WV-HRVT1 and WV-HRVT2 was not statistically significant (median and interquartile range = 4.8; 4.8 to 5.4 vs 4.8; 4.2 to 5.4 km/h); the correlation between WV-HRVT1 and WV-HRVT2 was significant (r = 0.84); the intraclass correlation coefficient was high (0.92; 0.82 to 0.96), and the agreement was acceptable (-0.08 km/h; -0.92 to 0.87). The difference between WV-VT and WV-HRVT2 was not statistically significant (4.8; 4.8 to 5.4 vs 4.8; 4.2 to 5.4 km/h) and the agreement was acceptable (0.04 km/h; -1.28 to 1.36). HRVT assessment during walking is a reliable measure and permits the estimation of VT in adults. We suggest the use of the ISWT for the assessment of exercise capacity in middle-aged and older adults.

  5. The Relationships of Upper Tropospheric Water Vapor with Atmospheric Temperature, SST and Clouds in Different Tropical Ocean Basins

    Water vapor (WV) is a primary natural greenhouse gas and provides a positive feedback to climate change driven by increasing CO2. Variation of upper tropospheric (UT) water vapor is especially important for the greenhouse effect of water vapor. For global and tropical means, the interannual variation of UT WV is found approximately correlated with interannual variation of atmospheric temperature and sea surface temperature (SST). However, regional variability of UT WV and its relationship with temperature, SST and clouds has yet been well documented. In this study, we analyze five years of UT observations from Aura Microwave Limb Sounder (MLS) in four tropical ocean basins (the Western Pacific, the Eastern Pacific, the Atlantic and Indian Oceans) and examine the correlations of UT WV with temperature, SST and clouds. The observed correlations are compared with climate model simulations for the 20th century and 21st century in a global warming scenario. It is found that the observed interannual variation of basin-averaged UT WV is strongly correlated with that of the UT temperature and tropical-mean SST for all four basins. However, the correlations with basin-averaged ice water content (IWC), cloud fraction, and precipitation are much higher in the Eastern Pacific and the Indian Ocean than in the Western Pacific and the Atlantic Ocean. Model simulations of the 20th century approximately capture the observed correlations of UT WV with temperature, SST and clouds in all basins, but with less variability. For the climate change projections of UT WV in each basin, the Eastern Pacific appears to deviate from the rest of the ocean basins in terms of the regression of UT WV changes on tropical-mean SST or temperature changes. We speculate that this is related to the stronger correlation of UT WV with clouds in the Eastern Pacific than in other basins. Thus, accurate representation of clouds is particularly important to the simulation and projection of UT WV in the Eastern

    Clinical translation of sustained release formulations for local anesthetics has been limited by adverse tissue reaction. Exparel™ (DepoFoam bupivacaine) is a new liposomal local anesthetic formulation whose biocompatibility near nerve tissue is not well characterized. Exparel™ injection caused sciatic nerve blockade in rats lasting 240 minutes compared to 120 minutes for 0.5% (w/v) bupivacaine HCl and 210 minutes for 1.31% (w/v) bupivacaine HCl (same bupivacaine content as Exparel™). On histologic sections four days after injection, median inflammation scores in the Exparel™ group (2.5 of 4) were slightly higher than in groups treated with bupivacaine solutions (score 2). Myotoxicity scores in the Exparel™ group (2.5 of 6) were similar to in the 0.5% (w/v) bupivacaine HCl group (3), but significantly less than in the 1.31% (w/v) bupivacaine HCl group (5). After two weeks, inflammation from Exparel™ (score 2 of 6) was greater than from 0.5% (w/v) bupivacaine HCl (1) and similar to that from 1.31% (w/v) bupivacaine HCl (1). Myotoxicity in all three groups was not statistically significantly different. No neurotoxicity was detected in any group. Tissue reaction to Exparel™ was similar to that of 0.5% (w/v) bupivacaine HCl. Surveillance for local tissue injury will be important during future clinical evaluation. PMID:24612918

    This workshop was held at the Morgantown Energy Technology Center (METC) in Morgantown, West Virginia, on July 11--12, 1995. The workshop sought to establish a foundation for continued dialogue between industry and the DOE to ensure that industry's experiences, lessons learned, and recommendations are incorporated into D and D program policy, strategy, and plans. The mission of the D and D Focus Area is to develop improved technologies, processes and products, to characterize, deactivate, survey, maintain, decontaminate, dismantle, and dispose of DOE surplus structures, buildings, and contents. The target is a five-to-one return on investment through cost avoidance. The cornerstone of the D and D focus area activities is large-scale demonstration projects that actually decontaminate, decommission, and dispose of a building. The aim is to demonstrate innovative D and D technologies as part of an ongoing DOE D and D project. OTD would pay the incremental cost of demonstrating the innovative technologies. The goal is to have the first demonstration project completed within the next 2 years. The intent is to select projects, or a project, with visible impact so all of the stakeholders know that a building was removed, and demonstrate at a scale that is convincing to the customers in the EM program so they feel comfortable using it in subsequent D and D projects. The plan is to use a D and D integrating contractor who can then use the expertise in this project to use in jobs at other DOE sites

    The Fuels Technology Contractors Review Meeting was held November 16-18, 1993, at the Morgantown Energy Technology Center (METC) in Morgantown, West Virginia. This meeting was sponsored and hosted by METC, the Office of Fossil Energy, U.S. Department of Energy (DOE). METC periodically provides an opportunity to bring together all of the R&D participants in a DOE-sponsored contractors review meeting to present key results of their research and to provide technology transfer to the active research community and to the interested public. This meeting was previously called the Natural Gas Technology Contractors Review Meeting. This year it was expanded to include DOE-sponsored research on oil shale and tar sands and so was retitled the Fuels Technology Contractors Review Meeting. Current research activities include efforts in both natural gas and liquid fuels. The natural gas portion of the meeting included discussions of results summarizing work being conducted in fracture systems, both natural and induced; drilling, completion, and stimulation research; resource characterization; delivery and storage; gas to liquids research; and environmental issues. The meeting also included project and technology summaries on research in oil shale, tar sands, and mild coal gasification, and summaries of work in natural-gas fuel cells and natural-gas turbines. The format included oral and poster session presentations. Individual papers have been processed separately for inclusion in the Energy Science and Technology database.

    Activities in environmental analysis support included assistance to the Morgantown and Pittsburgh Energy Technology Centers (METC and PETC) in reviewing and preparing documents required by the National Environmental Policy Act (NEPA) for several projects selected for the Clean Coal Technology (CCT) Program. A key milestone was the completion for PETC of the final Environmental Impact Statement (EIS) for the Healy Clean Coal Project (HCCP) in Healy, Alaska. This work is notable because it is the first site-specific EIS completed for the CCT Program. Another important activity was the preparation for METC of a draft Environmental Assessment (EA) for the Externally Fired Combined Cycle (EFCC) Project in Warren, Pennsylvania. Also, the final EA was completed for the Gasification Product Improvement Facility (GPIF), a proposed project near Morgantown, West Virginia, which is part of METC's R ampersand D Program. In addition, ORNL staff members published a Technical Memorandum entitled open-quotes Potential Effects of Clean Coal Technologies on Acid Precipitation, Greenhouse Gases, and Solid Waste Disposalclose quotes which documents the findings of three open-quotes white papersclose quotes prepared for DOE/FE

    The scope of this project was changed during the course of the project. Phase I of the project was designed to have the National Alternative Fuels Training Consortium (NAFTC), together with its partners, manage the Hydrogen Vehicle Test Project at the Yeager Airport in conjunction with the Central West Virginia Regional Airport Authority (CWVRAA) in coordination with the United States Department of Energy National Energy Technology Laboratory (U.S. DOE NETL). This program would allow testing and evaluation of the use of hydrogen vehicles in the state of West Virginia utilizing the hydrogen fueling station at Yeager Airport. The NAFTC and CWVRAA to raise awareness and foster a greater understanding of hydrogen fuel and hydrogen-powered vehicles through a targeted utilization and outreach and education effort. After initial implementation of the project, the project added, determine the source(s) of supply for hydrogen powered vehicles that could be used for the testing. After completion of this, testing was begun at Yeager Airport. During the course of the project, the station at Yeager Airport was closed and moved to Morgantown and the West Virginia University Research Corporation. The vehicles were then moved to Morgantown and a vehicle owned by the CWVRAA was purchased to complete the project at the new location. Because of a number of issues detailed in the report for DE-FE0002994 and in this report, this project did not get to evaluate the effectiveness of the vehicles as planned.

    DEFF Research Database (Denmark)

    Malysz, J; Thuneberg, L; Mikkelsen, Hanne Birte

    1996-01-01

    The small intestine of W/Wv mice lacks both the network of interstitial cells of Cajal (ICC), associated with Auerbach's plexus, and pacemaker activity, i.e., it does not generate slow-wave-type action potentials. The W/Wv muscle preparations showed a wide variety of electrical activities, ranging...... from total quiescence to generation of action potentials at regular or irregular frequency with or without periods of quiescence. The action potentials consisted of a slow component with superimposed spikes, preceded by a slowly developing depolarization and followed by a transient hyperpolarization....... The action potentials were completely abolished by L-type Ca2+ channel blockers. W/Wv mice responded to K+ channel blockade (0.5 mM Ba2+ or 10 mM tetraethylammonium chloride) with effects on amplitude, frequency, rate of rise, and duration of the action potentials. In quiescent tissues from W/Wv mice, K...

    2014-01-01

    Full Text Available Tissue engineering fibrous scaffolds serve as three-dimensional (3D environmental framework by mimicking the extracellular matrix (ECM for cells to grow. Biodegradable polycaprolactone (PCL microfibers were fabricated to mimic the ECM as a scaffold with 7.5% (w/v and 12.5% (w/v concentrations. Lower PCL concentration of 7.5% (w/v resulted in microfibers with bead defects. The average diameter of fibers increased at higher voltage and the distance of tip to collector. Further investigation was performed by the incorporation of nanosized hydroxyapatite (nHA into microfibers. The incorporation of 10% (w/w nHA with 7.5% (w/v PCL solution produced submicron sized beadless fibers. The microfibrous scaffolds were evaluated using various techniques. Biodegradable PCL and nHA/PCL could be promising for tissue engineering scaffold application.

  12. Kolliphor surfactants affect solubilization and bioavailability of fenofibrate. Studies of in vitro digestion and absorption in rats

    DEFF Research Database (Denmark)

    Berthelsen, Ragna; Holm, Rene; Jacobsen, Jette

    2015-01-01

    formulations only comprised an aqueous micellar solution of the model drug (fenofibrate) in varying concentrations (2–25% (w/v)) of the three tested surfactants. Increased concentrations of Kolliphor ELP and EL led to increased fenofibrate AUC0–24h values. For the Kolliphor RH40 formulations, an apparent...... fenofibrate absorption optimum was seen at 15% (w/v) surfactant, displaying both the highest AUC0–24h and Cmax. The reduced absorption of fenofibrate from the formulation containing the highest level of surfactant (25% w/v) was thought to be caused by some degree of trapping within Kolliphor RH40 micelles....... In vitro, Kolliphor ELP and EL were found to be more prone to digestion than Kolliphor RH40, though not affecting the in vivo results. The highest fenofibrate bioavailability was attained from formulations with high Kolliphor ELP/EL levels (25% (w/v)), indicating that these surfactants are the better...

  13. Direct injection of water vapor into the stratosphere by volcanic eruptions

    Science.gov (United States)

    Sioris, Christopher E.; Malo, Alain; McLinden, Chris A.; D'Amours, Real

    2016-07-01

    While theoretical studies show that water vapor (WV) can be directly injected into the stratosphere during a volcanic eruption, few observations of such a phenomenon exist. The Microwave Limb Sounder observed stratospheric injection of WV following the 2015 Calbuco eruption. Lower stratospheric mixing ratios exceeded 10 ppmv for a few days downwind of the injection location. Plume transport is confirmed by back trajectory modeling. Due to the short duration and limited spatial extent of the enhancement, climatic impact is expected to be negligible. This letter provides spatiotemporal analysis of a volcanogenic pulse of lower stratospheric WV as it dispersed. The inferred mass of stratospheric WV from this eruption of 2 megaton (Mt) and the rapid evanescence of the enhancement are similar to what has been observed for other eruptions, suggesting that injection by moderately explosive eruptions is not an effective mechanism for large-scale stratospheric hydration.

    Four ethanologenic ethanol-tolerant yeast strains, Saccharomyces cerevisiae (ATKU132), Saccharomycodes ludwigii (ATKU47), and Issatchenkia orientalis (ATKU5-60 and ATKU5-70), were isolated by an enrichment technique in yeast extract peptone dextrose (YPD) medium supplemented with 10% (v/v) ethanol at 30°C. Among non-Saccharomyces yeasts, Sd. ludwigii ATKU47 exhibited the highest ethanol-tolerance and ethanol production, which was similar to S. cerevisiae ATKU132. The maximum range of ethanol concentrations produced at 37°C by S. cerevisiae ATKU132 and Sd. ludwigii ATKU47 from an initial D-glucose concentration of 20% (w/v) and 28% (w/v) sugarcane molasses were 9.46-9.82% (w/v) and 8.07-8.32% (w/v), respectively.

  18. Properties and stabilization of an extracellular alpha-glucosidase from the extremely thermophilic archaebacteria Thermococcus strain AN1: enzyme activity at 130 degrees C.

    Science.gov (United States)

    Piller, K; Daniel, R M; Petach, H H

    1996-01-04

    An extracellular alpha-glucosidase from the thermophilic archaebacterium Thermococcus strain AN1 was purified 875-fold in five steps (Hiload Q-Sepharose, phenyl Sepharose, HPHT-hydroxyapatite, gel filtration and Mono Q chromatography) with a yield of 4%. It is a monomer with a molecular mass of about 60 kDa and a pI around 5. At 98 degrees C, the purified enzyme in buffer has a half-life around 35 min, which is increased to around 215 min in presence of 1% (w/v) dithiothreitol and 1% (w/v) BSA. Dithiothreitol (1%, w/v) and BSA (0.4%, w/v) also substantially increase the enzyme activity. The Km at 75 degrees C is 0.41 mM with pNP-alpha-D-glucopyranoside as substrate. The substrate preference of the enzyme is: pNP-alpha-D-glucoside > nigerose > panose > palatinose > isomaltose > maltose and turanose. No activity was found against starch, pullulan, amylose, maltotriose, maltotetraose, isomaltotriose, cellobiose and beta-gentiobiose. A variety of techniques including immobolization (e.g., on epoxy and glass beads), chemical modification (cross- and cocross-linking) and the use of additives (including polyhydroxylic molecules, BSA, salts, etc.) were applied to enhance stability at temperatures above 100 degrees C. The half-life could be increased from about 4 min at 100 degrees C to 30-60 min at 130 degrees C in presence of 90% (w/v) sorbitol, 1% (w/v) dithiothreitol and 1% (w/v) BSA, and by cross-linking with BSA in the presence of 90% (w/v) sorbitol. The stabilized enzyme showed good activity at 130 degrees C.

In yoghurt samples, physical-chemical properties, texture, color and sensory analysis were determined on the 1st, 5th, 10th and 14th days of storage, while total phenolics (TF levels were determined on the 14th, 24th, 32nd, 48th, 72nd, 120th, 240th and 336th hours of storage. In all samples during storage, hardness and viscosity increased along with the acidity increase, although the increases in YTSM and YTSMC were lower than in YTSMX. In YTSMX, in spite of the increase in acidity after the 1st day, serum separation was very low while viscosity and hardness values were higher compared to the other samples. YTSMX was found to be superior to the other samples in terms of physicochemical, textural, microbiological and sensory properties. Total phenolic contents and L*a*b* levels increased in all samples throughout storage, the highest values of which were in YTSMX. After the 5th day of the storage, Lactobacillus delbrueckii subsp. bulgaricus became the dominant microbial flora. After the 5th day of storage, Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus levels were highest in YTSMX.

    Survival of bacterial pathogens in different environments is due, in part, to their ability to form biofilms. Four wild-type Salmonella enterica strains, two Oranienburg and two Saintpaul isolated from river water and animal feces, were tested for biofilm formation at the air-liquid interface under stressful conditions (pH and salinity treatments such as pH 3, NaCl 4.5 w/v; pH 7, NaCl 4.5 w/v; pH 10, NaCl 4.5 w/v; pH 3, Nacl 0.5 w/v; pH 7, NaCl 0.5 w/v; and pH 10, NaCl 0.5 w/v); Salmonella Typhimurium DT104 was used as a control strain. Salmonella Oranienburg and Saintpaul from feces were moderately hydrophobic and motile, while S. Saintpaul from water and the control strain S. Typhimurium showed high hydrophobicity, which helped them form more resistant biofilms than S. Oranienburg. Under stressful conditions, all strains experienced difficulties in forming biofilms. Salmonella Saintpaul and Typhimurium expressed the red dry and rough (RDAR) morphotype and were able to form biofilm at air-liquid interface, contrarily to Oranienburg that showed incomplete rough morphology. This study contributes to the knowledge of biofilm formation as a survival strategy for Salmonella in aquatic environments.

    Full Text Available Since WorldView-2 (WV-2 images are widely used in various fields, there is a high demand for the use of high-quality pansharpened WV-2 images for different application purposes. With respect to the novelty of the WV-2 multispectral (MS and panchromatic (PAN bands, the performances of eight state-of-art pan-sharpening methods for WV-2 imagery including six datasets from three WV-2 scenes were assessed in this study using both quality indices and information indices, along with visual inspection. The normalized difference vegetation index, normalized difference water index, and morphological building index, which are widely used in applications related to land cover classification, the extraction of vegetation areas, buildings, and water bodies, were employed in this work to evaluate the performance of different pansharpening methods in terms of information presentation ability. The experimental results show that the Haze- and Ratio-based, adaptive Gram-Schmidt, Generalized Laplacian pyramids (GLP methods using enhanced spectral distortion minimal model and enhanced context-based decision model methods are good choices for producing fused WV-2 images used for image interpretation and the extraction of urban buildings. The two GLP-based methods are better choices than the other methods, if the fused images will be used for applications related to vegetation and water-bodies.

    Full Text Available Abstract Background The muscle layers of murine gastric fundus have no interstitial cells of Cajal at the level of the myenteric plexus and only possess intramuscular interstitial cells and this tissue does not generate electric slow waves. The absence of intramuscular interstitial cells in W/WV mutants provides a unique opportunity to study the molecular changes that are associated with the loss of these intercalating cells. Method The gene expression profile of the gastric fundus of wild type and W/WV mice was assayed by murine microarray analysis displaying a total of 8734 elements. Queried genes from the microarray analysis were confirmed by semi-quantitative reverse transcription-polymerase chain reaction. Results Twenty-one genes were differentially expressed in wild type and W/WV mice. Eleven transcripts had 2.0–2.5 fold higher mRNA expression in W/WV gastric fundus when compared to wild type tissues. Ten transcripts had 2.1–3.9 fold lower expression in W/WV mutants in comparison with wild type animals. None of these genes have ever been implicated in any bowel motility function. Conclusions These data provides evidence that several important genes have significantly changed in the murine fundus of W/WV mutants that lack intramuscular interstitial cells of Cajal and have reduced enteric motor neurotransmission.

    This laboratory study was carried out to examine the effect of Lantana sp. leaf extracts on Oulema pectoralis mortality. Oulema pectoralis, the flower eating yellow beetle, is one of the most important pest of orchid. As this beetle feeds on orchid flower, the yield loss is 100 % due to zero tolerance to damage. Two different types of extraction were conducted, extraction with water and with organic solvent (ethanol). Five solutions of Lantana sp. extract were evaluated for their effectiveness against beetles. Water extract was prepared at concentrations of 5 % w/v, 10 % w/v and 20 % w/v; whilst organic solvent (ethanol) extract was prepared at concentrations of 5 % w/v and 10 % w/v. Ten replications were done for each treatment. Five adult O. pectoralis were placed on orchid flower painted with 1 mL test solution inside a glass beaker. Results showed that solution of Lantana sp. leaf extract was effective in controlling O. pectoralis beetle on orchid flower even at concentration as low as 10 % w/v (100 g of leaves blended with 1 litre of water or ethanol).

    Although birthplace data are routinely collected in the participating Surveillance, Epidemiology, and End Results (SEER) registries, such data are missing in a nonrandom manner for a large percentage of cases. This hinders analysis of nativity-related cancer disparities. In the current study, the authors evaluated multiple imputation of nativity status among Hispanic patients diagnosed with cervical, prostate, and colorectal cancer and demonstrated the effect of multiple imputation on apparent nativity disparities in survival. Multiple imputation by logistic regression was used to generate nativity values (US-born vs foreign-born) using a priori-defined variables. The accuracy of the method was evaluated among a subset of cases. Kaplan-Meier curves were used to illustrate the effect of imputation by comparing survival among US-born and foreign-born Hispanics, with and without imputation of nativity. Birthplace was missing for 31%, 49%, and 39%, respectively, of cases of cervical, prostate, and colorectal cancer. The sensitivity of the imputation strategy for detecting foreign-born status was ≥90% and the specificity was ≥86%. The agreement between the true and imputed values was ≥0.80 and the misclassification error was ≤10%. Kaplan-Meier survival curves indicated different associations between nativity and survival when nativity was imputed versus when cases with missing birthplace were omitted from the analysis. Multiple imputation using variables available in the SEER data file can be used to accurately detect foreign-born status. This simple strategy may help researchers to disaggregate analyses by nativity and uncover important nativity disparities in regard to cancer diagnosis, treatment, and survival. © 2013 American Cancer Society.

    Full Text Available Abstract Background The association between area characteristics and birth outcomes is modified by race. Whether such associations vary according to social class indicators beyond race has not been assessed. Methods This study evaluated effect modification by maternal birthplace and education of the relationship between neighbourhood characteristics and birth outcomes of newborns from 1999–2003 in the province of Québec, Canada (N = 353,120 births. Areas (N = 143 were defined as administrative local health service delivery districts. Multi-level logistic regression was used to model the association between three area characteristics (median household income, immigrant density and income inequality and the two outcomes preterm birth (PTB and small-for-gestational age (SGA birth. Effect modification by social class indicators was evaluated in analyses stratified according to maternal birthplace and education. Results Relative to the lowest tertile, high median household income was associated with SGA birth among Canadian-born mothers (odds ratio (OR 1.13, 95% confidence interval (CI 1.06, 1.20 and mothers with high school education or less (OR 1.13, 95% CI 1.02, 1.24. Associations between median household income and PTB were weaker. Relative to the highest tertile, low immigrant density was associated with a lower odds of PTB among foreign-born mothers (OR 0.79, 95% CI 0.63, 1.00 but a higher odds of PTB among Canadian-born mothers (OR 1.14, 95% CI 1.07, 1.21. Associations with income inequality were weak or absent. Conclusion The association between area factors and birth outcomes is modified by maternal birthplace and education. Studies have found that race interacts in a similar manner. Public health policies focussed on perinatal health must consider the interaction between individual and area characteristics.

    Our objective was to characterize the nonequilibrium thermal behavior of frozen aqueous solutions containing PEG and sucrose. Aqueous solutions of (i) sucrose (10%, w/v) with different concentrations of PEG (1-20%, w/v), and (ii) PEG (10%, w/v) with different concentrations of sucrose (2-20%, w/v), were cooled to -70 degrees C at 5 degrees C/min and heated to 25 degrees C at 2 degrees C/min in a differential scanning calorimeter. Annealing was performed at temperatures ranging from -50 to -20 degrees C for 2 or 6 h. Similar experiments were also performed in the low-temperature stage of a powder X-ray diffractometer. A limited number of additional DSC experiments were performed wherein the samples were cooled to -100 degrees C. In unannealed systems with a fixed sucrose concentration (10%, w/v), the T'g decreased from -35 to -48 degrees C when PEG concentration was increased from 1% to 20% (w/v). On annealing at -25 degrees C, PEG crystallized. This was evident from the increase in T'g and the appearance of a secondary melting endotherm in the DSC. Low-temperature XRD provided direct evidence of PEG crystallization. Annealing at temperatures w/v), the T'g increased from -50 to -40 degrees C when sucrose concentration was increased from 5% to 50%, w/v. As the annealing time increased (at -25 degrees C), the T'g approached that of a sucrose-water system, reflecting progressive PEG crystallization. A second glass transition at approximately -65 degrees C was evident in unannealed systems [10%, w/v sucrose and 10 (or 20%), w/v PEG] cooled to -100 degrees C. Investigation of the nonequilibrium behavior of frozen PEG-sucrose-water ternary system revealed phase separation in the freeze-concentrate. Annealing facilitated PEG crystallization.

    Full Text Available This study examines two key parameters of the hydrological cycle, water vapor (WV and precipitation rates (PR, as modelled by the chemistry transport model MATCH (Model of Atmospheric Transport and Chemistry driven by National Centers for Environmental Prediction (NCEP reanalysis data (NRA. For model output evaluation we primarily employ WV total column data from the Global Ozone Monitoring Experiment (GOME on ERS-2, which is the only instrument capable measuring WV on a global scale and over all surface types with a substantial data record from 1995 to the present. We find that MATCH and NRA WV and PR distributions are closely related, but that significant regional differences in both parameters exist in magnitude and distribution patterns when compared to the observations. We also find that WV residual patterns between model and observations show remarkable similarities to residuals observed in the PR when comparing MATCH and NRA output to observations comprised by the Global Precipitation Climatology Project (GPCP. We conclude that deficiencies in model parameters shared by MATCH and NRA, like in the surface evaporation rates and regional transport patterns, are likely to lead to the observed differences. Monthly average regional differences between MATCH modelled WV columns and the observations can be as large as 2 cm, based on the analysis of three years. Differences in the global mean WV values are, however, below 0.1 cm. Regional differences in the PR between MATCH and GPCP can be above 0.5 cm per day and MATCH computes on average a higher PR than what has been observed. The lower water vapor content of MATCH is related to shorter model WV residence times by up to 1 day as compared to the observations. We find that MATCH has problems in modelling the WV content in regions of strong upward convection like, for example, along the Inter Tropical Convergence Zone, where it appears to be generally too dry as compared to the observations.

    Full Text Available This paper examines the relationships between satisfaction with life in general, particular domains of life, the partner, and parental relationships with existing children, and subsequent fertility. The data are from 2,948 women and 2,622 men aged 15 to 44 years from a longitudinal survey of the household population in Australia. For both sexes a strong positive relationship between prior satisfaction with life and fertility two years later is found. Men's satisfaction with their partner and with their partner's relationship with existing children are positively related to fertility. Fertility is also related to age, parity, marital status, education, employment and birthplace.

    We use census microdata to assess the levels of educational homogamy in six Latin American countries: Argentina, Brazil, Chile, Costa Rica, Ecuador and Mexico. This paper contributes to the literature on homogamy in three ways. First, by conducting a comparative analysis between countries belonging to the still little-studied region of Latin America, which is still undergoing intense and varied processes of demographic, economic, social, and political modernization. Second, by simultaneously including variables of structural and individual nature. Finally, by making progress with respect to the interactions between educational homogamy and other important variables associated with high levels of social inequality in the region: race, ethnicity and birthplace.

    The birthplace of the specialty of psychiatry was in the asylum, which was created to divert patients from workhouses where the most disadvantaged and destitute people with mental illness were to be found. The current welfare reforms are endangering the welfare and livelihood of the most disadvantaged of our patients. These reforms in the authors' opinion are related more to the historical cycle of societal attitude to homeless people than to seeing them as the undeserving poor. This is particularly true since the current economic crisis was not caused by the poor, so it is very unfair that our poorest patients should suffer most as a result of the welfare reforms.

    Full Text Available The contribution of Adam Smith for liberalism was great, but it is not limited to bringing an insane and unreasonable quest for freedom, as if all the costs were possible for such purpose. Adam Smith brings the birthplace of fundamental rights, to call for the need for recognition of individual liberties, although predicting problems for the exercise of such powers without limits. The idea of the text is to bring the initial outlook for the construction of fundamental rights in an individual prism and after its weighting in a mass spectrum as well as the subsequent discussion which should prevail.

    It is difficult if not impossible to determine when mankind first systematically applied color to a textile substrate. The first colored fabrics were probably nonwoven felts painted in imitation of animal skins. The first dyeings were probably actually little more than stains from the juice of berries. Ancient Greek writers described painted fabrics worn by the tribes of Asia Minor. But just where did the ancient craft have its origins? Was there one original birthplace or were there a number of simultaneous beginnings around the world?

    We hypothesized that mast cells modulate lung inflammation that develops after acute ozone (O3) exposure. Two tests were done: (1) genetically mast-cell-deficient (WBB6F1-W/Wv, WCB6F1-SI/SId) and bone-marrow-transplanted W/Wv mice were exposed to O3 or filtered air, and the inflammatory responses were compared with those of mast-cell-sufficient congenic mice (WBB6F1-(+)/+, WCB6F1-(+)/+); (2) genetically O3-susceptible C57BL/6J mice were treated pharmacologically with putative mast-cell modulators or vehicle, and the O3-induced inflammatory responses were compared. Mice were exposed to 1.75 ppm O3 or air for 3 h, and lung inflammation was assessed by bronchoalveolar lavage (BAL) 6 and 24 h after exposure. Relative to O3-exposed W/Wv and SI/SId mice, the mean numbers of lavageable polymorphonuclear leukocytes (PMNs) and total BAL protein concentration (a marker of permeability) were significantly greater in the respective O3-exposed normal congenic +/+ mice (p < 0.05). Mast cells were reconstituted in W/Wv mice by transplantation of bone marrow cells from congenic +/+ mice, and O3-induced lung inflammation was assessed in the mast-cell-replete W/Wv mice. After O3 exposure, the changes in lavageable PMNs and total protein of mast-cell-replete W/Wv mice were not different from age-matched normal +/+ control mice, and they were significantly greater than those of sham-transplanted W/Wv mice (p < 0.05). Genetically susceptible C57BL/6J mice were pretreated with a mast-cell stabilizer (nedocromil sodium), secretagogue (compound 48/80), or vehicle, and the mice were exposed to O3.

    Full Text Available The specific aims of this study were to select the favorable prebiotic for L casei-01 as well as the suitable inoculum of the probiotic for fermented soy with ACE-inhibitory potential. For that purpose the metabolic activity of L casei-01 in soymilk supplemented with(1.5% w/v prebiotics Fructooligosaccharide (FOS or oligofructose enriched inulin (Synergy 1 was assessed. The evaluated parameters were: pH, viable cell counts, proteolysis, organic acid production and inhibition of angiotensine converting enzyme activity (IACE. The cell growth of L casei-01 reached the recommended therapeutic level of 9.58 ± 0.035 log cfu mL-1 for low inoculum samples (0.005 and 0.01%w/v and 11.543 ± 0.13 log cfu mL-1 for high inoculum samples (0.075 and 0.1%w/v regardless of the prebiotic used. The lower pH during fermentation, faster cell growth and superior proteolysis in Synergy 1 samples indicated better utilization of that prebiotic vs. FOS. The hydrolysis depended on the prebiotic used, showing higher values in Synergy 1 samples. The faster proteolysis was confirmed by SDSPAG electrophoresis. The Mw of polypeptides in the synbiotic end-products were lower than 30kD. The observed values for inhibition of ACE activity were app. 71, 74, 77 and 78% for inoculum rates of 0.005, 0.01, 0.075 and 0.1% w/v, respectively. Based on the results obtained in our study, the prebiotic Synergy 1 (1.5% w/v and L. casei-01 at inoculum of 0.01% w/v for low dose and 0.075% w/v for high dose were considered more favorable for the production of synbiotic soy drink with antihypertensive potential.

    The antigenicity of seasonal human influenza virus changes continuously; thus, a cross-protective influenza vaccine design needs to be established. Intranasal immunization with an influenza split-virion (SV) vaccine and a mucosal adjuvant induces cross-protection; however, no mucosal adjuvant has been assessed clinically. Formalin-inactivated intact human and avian viruses alone (without adjuvant) induce cross-protection against the highly pathogenic H5N1 avian influenza virus. However, it is unknown whether seasonal human influenza formalin-inactivated whole-virion (WV) vaccine alone induces cross-protection against strains within a subtype or in a different subtype of human influenza virus. Furthermore, there are few reports comparing the cross-protective efficacy of the WV vaccine and SV vaccine-mucosal adjuvant mixtures. Here, we found that the intranasal human influenza WV vaccine alone induced both the innate immune response and acquired immune response, resulting in cross-protection against drift variants within a subtype of human influenza virus. The cross-protective efficacy conferred by the WV vaccine in intranasally immunized mice was almost the same as that conferred by a mixture of SV vaccine and adjuvants. The level of cross-protective efficacy was correlated with the cross-reactive neutralizing antibody titer in the nasal wash and bronchoalveolar fluids. However, neither the SV vaccine with adjuvant nor the WV vaccine induced cross-reactive virus-specific cytotoxic T-lymphocyte activity. These results suggest that the intranasal human WV vaccine injection alone is effective against variants within a virus subtype, mainly through a humoral immune response, and that the cross-protection elicited by the WV vaccine and the SV vaccine plus mucosal adjuvants is similar.

    The effect of high hydrostatic pressure (HHP) on the susceptibility of potato starch (25%, w/v) suspended in water to degradation by exposure to bacterial α-amylase (0.02%, 0.04% and 0.06%, w/v) for 40 min at 25°C was investigated. Significant differences (p starch (PS) exposed to α-amylase (0.06%, w/v) showed a significantly greater degree of hydrolysis and amount of reducing sugar released compared to α-amylase at a concentration of 0.04% (w/v) or 0.02% (w/v). Native PS (NPS) granules have a spherical and elliptical form with a smooth surface, whereas the hydrolyzed NPS (hNPS) and hydrolyzed HHP-treated PS granules showed irregular and ruptured forms with several cracks and holes on the surface. Hydrolysis of HHP-treated PS by α-amylase could decrease the average granule size significantly (p starch in both the ordered and the amorphous structure, especially in hydrolyzed HHP600 PS. The B-type of hydrolyzed HHP600 PS with α-amylase at a concentration 0.06% (w/v) changed to a B+V type with an additional peak at 2θ = 19.36°. The HHP600 starch with 0.06% (w/v) α-amylase displayed the lowest value of T o (onset temperature), T c (conclusion temperature) and ΔH gel (enthalpies of gelatinization). These results indicate the pre-HHP treatment of NPS leads to increased susceptibility of the granules to enzymatic degradation and eventually changes of both the amorphous and the crystalline structures.

    The effect of enhancing wood vinegar (WV) with a mixture of biochar (B) and zeolite (Z) to compost pig manure (PM) in a 130 L reactor was evaluated to determine the levels of greenhouse gas (GHG) and ammonia emissions. Six treatments were prepared in a 2:1 ratio of PM mixed with wheat straw (WS; dry weight basis): PM + WS (control), PM + WS + 10%B, PM + WS + 10%B + 10%Z, and PM + WS with 0.5%, 1.0% and 2.0%WV combined with 10%B + 10%Z. These were composted for 50 days, and the results indicated that the combined use of B, Z, and WV could shorten the thermophilic phase and improve the maturity of compost compared to the control treatment. In addition, WV mixed with B and Z could reduce ammonia loss by 64.45-74.32% and decrease CO 2 , CH 4 , and N 2 O emissions by 33.90-46.98%, 50.39-61.15%, and 79.51-81.10%, respectively. Furthermore, compared to treatments in which B and B + Z were added, adding WV was more efficient to reduce the nitrogen and carbon loss, and the 10%B + 10%Z + 2%WV treatment presented the lowest loss of carbon (9.16%) and nitrogen (0.75%). Based on the maturity indexes used, nitrogen conservation, and efficiency of GHG emissions reduction, the treatment 10%B + 10%Z + 2%WV is suggested for efficient PM composting.

    Full Text Available WorldView commercial imaging satellites comprise a constellation developed by DigitalGlobe Inc. (Longmont, CO, USA. Worldview-3 (WV-3, currently planned for launch in 2014, will have 8 spectral bands in the Visible and Near-Infrared (VNIR, and an additional 8 bands in the Short-Wave-Infrared (SWIR; the approximately 1.0–2.5 μm spectral range. WV-3 will be the first commercial system with both high spatial resolution and multispectral SWIR capability. Airborne Visible/Infrared Imaging Spectrometer (AVIRIS data collected at 3 m spatial resolution with 86 SWIR bands having 10 nm spectral resolution were used to simulate the new WV-3 SWIR data. AVIRIS data were converted to reflectance, geographically registered, and resized to the proposed 3.7 and 7.5 m spatial resolutions. WV-3 SWIR band pass functions were used to spectrally resample the data to the proposed 8 SWIR bands. Characteristic reflectance signatures extracted from the data for known mineral locations (endmembers were used to map spatial locations of specific minerals. The WV-3 results, when compared to spectral mapping using the full AVIRIS SWIR dataset, illustrate that the WV-3 spectral bands should permit identification and mapping of some key minerals, however, minerals with similar spectral features may be confused and will not be mapped with the same detail as using hyperspectral systems. The high spatial resolution should provide detailed mapping of complex alteration mineral patterns not achievable by current multispectral systems. The WV-3 simulation results are promising and indicate that this sensor will be a significant tool for geologic remote sensing.

  6. Exceptional hexose-fermenting ability of the xylitol-producing yeast Candida guilliermondii FTI 20037.

    The yeast Candida guilliermondii FTI 20037 is well-known for its ability to produce xylitol from xylose. Recently, this strain was found to produce greater than 5% (w/v) ethanol from glucose. This level of ethanol is typically not exceeded by wild-type strains of other native pentose-fermenting yeasts. This prompted the current study to examine the ability of C. guilliermondii FTI 20037 to utilize and ferment high concentrations of each of the hexoses commonly found in lignocellulosic hydrolysates. In defined media, FTI 20037 fermented 14.4%-25.9% (w/v) of glucose, mannose or galactose individually to ethanol in concentrations ranging from 6% to 9.3% (w/v). Fermentation was completed within 36 h (for glucose) to 100 h (for galactose). In 25.9% (w/v) glucose, FTI 20037 produced 9.3% (w/v) ethanol within 40 h. FTI 20037 produced xylitol exclusively when xylose was given as the sole carbon source. The strain utilized arabinose poorly. Under the same fermentation conditions, an industrial Saccharomyces cerevisiae strain produced slightly higher levels of ethanol [9.9% (w/v)] from 25.0% (w/v) glucose. Another pentose-fermenting yeast Pachysolen tannophilus also fermented high concentrations of glucose and mannose to produce relatively high peak ethanol concentrations; however, this yeast required considerably longer to completely consume these hexoses. The ability of FTI 20037 to produce high level of ethanol rapidly from glucose is remarkable. To our knowledge, this is the first known instance of a non-modified native xylose-fermenting yeast strain able to produce such high levels of ethanol from glucose as rapidly as S. cerevisiae in a defined medium.

    The upper aquifers in the A ampersand M area of the Savannah River Site are known to be contaminated by chlorinated solvents. Remediation plans depend critically on continuity of a confining zone known as the Crouch Branch Confining Unit (C8CU), which occurs at depths between about 250 feet and 300 feet. Under DOE Contract No: DE-AC21-92MC29, administered by Morgantown Energy Technology Center (METC) surface and borehole geophysical methods were tested and further developed between 1993 and 1995 to map the lithology (clay content) and stratigraphy of the CBCU. It was found that time domain electromagnetics (TDEM) soundings were effective in mapping lithology and changes in lithology, and shear (S-) wave reflection surveys were effective in mapping stratigraphy. An integrated interpretation of the two methods yielded a rather complete image of lithology and stratigraphy of the CBCU

    A patented dynamic mechanical filter developed by InnovaTech was previously shown to remove fine particulate matter from industrial process gas streams at ambient temperatures and pressures. An all-metal, high-temperature version of this novel media-less filter was fabricated under this Cooperative Research and Development Agreement (CRADA) with DOE/NETL-Morgantown for hot gas testing of the device. The technology is entirely different in both concept and design from conventional vortex separators, cyclones, or porous media filters. This new filtration concept is capable of separating heavy loading of fine particles without blinding, fouling or bridging, and would require minimal operational costs over its anticipated multi-year service life. The all-metal filter design eliminates thermal stress cracking and premature failure prevalent in conventional porous ceramic filters. In contrast, conventional porous media filters (i.e., ceramic cross-flow or candles) easily foul, require periodic cleaning (typically backpulsing), frequent replacement and subsequent disposal

    The Morgantown Energy Technology Center (METC) has conducted a test program to develop a zinc ferrite-based high temperature desulfurization process which could be applied to fuel gas entering downstream components such as molten carbonate fuel cells or gas turbines. As a result of prior METC work with iron oxide and zinc oxide sorbents, zinc ferrite evolved as a candidate with the potential for high capacity, low equilibrium levels of H/sub 2/S, and structural stability after multiple regenerations. The program consisted of laboratory-scale testing with a two-inch diameter reactor and simulated fixed-bed gasifier gas; bench-scale testing with a six-inch diameter reactor and actual gas from the METC 42-inch fixed bed gasifier; as well as laboratory-scale testing of zinc ferrite with simulated fluidized bed gasifier gas.

    Morgantown Energy Technology Center (METC) of DOE has sponsored, and continues to sponsor, programs for the development of technology and market strategies which will lead to the commercialization of processes for the production of coproducts from mild gasification of coal. It has been recognized by DOE and industry that mild gasification is a promising technology with potential to economically convert coal into marketable products, thereby increasing domestic coal utilization. In this process, coal is devolatilized under non- oxidizing conditions at mild temperature (900--1100{degrees}F) and pressure (1--15psig). Condensation of the vapor will yield a liquid product that can be upgraded to a petroleum substitute, and the remaining gas can provide the fuel for the process. The residual char can be burned in a power plant. Thus, in a long-term national scenario, implementation of this process will result in significant decrease of imported oil and increase in coal utilization.

    During the last quarter of 1979, Sandia National Laboratories participated in an experiment with Thurlow Weed and Associates and the Morgantown Energy Technology Center. This Devonian Shale gas stimulation experiment was conducted in an area north of Columbus, Ohio. One purpose of the experiment was to apply the diagnostic instrumentation that is available for fracture mapping and characterization to increase our understanding of the stimulation technique. The induced fracture apparently followed a pre-existing fracture vertically from the borehole with an orientation of the N 62/sup 0/ E and in the latter stages of the stimulation turned into a shallower horizontal fracture. This fracture behavior was confirmed by several diagnostic analyses and demonstrates the insight that can be gained by fully instrumented stimulation experiments.

    This study was initiated during a successful test of the Coolside flue gas desulfurization technology at Ohio Edison`s Edgewater generating station in 1991. Coolside is a lime duct technology which is installed on the downstream side of the last heat exchanger. As tested by Ohio Edison, it also employs an alkali reagent, in this case NaOH, to enhance sulfur capture. The overall goal of this study was to develop sufficient chemical and physical data to insure the environmentally safe disposal of the material. This final report summarizes the important aspects of the project, but it does not present all of the data that was produced. Further details may be found in the monthly and quarterly reports that were filed with the Morgantown Energy Technology Center. This report is organized into six chapters which present the important conclusions of the principal areas of investigation.

    A bench-scale fluidized-bed bioreactor was operated for over 4 months to characterize the biooxidation of major organic pollutants in coal gasification wastewater obtained from the Morgantown Energy Technology Center. Monohydric phenol was degraded first, followed by more complex phenolics, including polycyclic aromatic hydrocarbons (PAHs). Organic components were assayed by methylene chloride extraction followed by gas chromatography. Genetic capability for degradation of naphthalene by the biofilm was identified by gene probe analysis. Further studies were conducted to determine if the existing biofilm could be enhanced for naphthalene degradation by supplemental inoculation with a microbial culture having good naphthalene-degrading capabilities. The biofilm response was monitored using gene probe techniques. An assessment of wastewater treatment technologies for coal conversion wastewaters was initiated. A bibliography was compiled, arrangements were initiated to collaborate with other investigators doing wastewater treatability studies, and a site visit was made to the Great Plains plant. 201 refs., 3 figs., 5 tabs.

    The ''Environmental Management Technology Leveraging Initiative,'' a cooperative agreement between the Global Environment and Technology Foundation and the Department of Energy-Morgantown Energy Technology Center, has completed its second year. This program, referred to as the Global Environmental Technology Enterprise (GETE) is an experiment to bring together the public and private sectors to identify, formulate, promote and refine methods to develop more cost-effective clean-up treatments. Working closely with Department of Energy officials, National Laboratory representatives, business people, academia, community groups, and other stakeholders, this program attempts to commercialize innovative, DOE-developed technologies. The methodology to do so incorporates three elements: business assistance, information, and outreach. A key advance this year was the development of a commercialization guidance document which can be used to diagnose the commercialization level and needs for innovative technologies

    A patented dynamic mechanical filter developed by InnovaTech was previously shown to remove fine particulate matter from industrial process gas streams at ambient temperatures and pressures. An all-metal, high-temperature version of this novel media-less filter was fabricated under this Cooperative Research and Development Agreement (CRADA) with DOE/NETL-Morgantown for hot gas testing of the device. The technology is entirely different in both concept and design from conventional vortex separators, cyclones, or porous media filters. This new filtration concept is capable of separating heavy loading of fine particles without blinding, fouling or bridging, and would require minimal operational costs over its anticipated multi-year service life. The all-metal filter design eliminates thermal stress cracking and premature failure prevalent in conventional porous ceramic filters. In contrast, conventional porous media filters (i.e., ceramic cross-flow or candles) easily foul, require periodic cleaning (typically backpulsing), frequent replacement and subsequent disposal.

    1980-01-01

    A solids heater which operates at up to 2000 F was designed, fabricated, installed and operated through checkout at the Morgantown Energy Technology Center at Morgantown, West Virginia. The system, designated the 2000 F Fluid Bed Solids Heater (FBSH) uses a fluidized bed to heat limestone to 600 F and aluminium oxide or silicon carbide to 2000 F and discharges heated solids upon demand. The FBSH with added valve handling and pressurization equipment is known as the Valve Hot Solids Test Unit and is intended for use by the US Department of Energy for testing of valves for severe service applications in coal conversion and utilization processes. The FBSH as designed and supplied by Combustion Power Company includes process equipment, controls, the enclosing building and other associated equipment. In the 600 F range of operation it can circulate limestone through two valve test trains simultaneously on a continuous basis. Only one valve test train is used for 2000 F solids and operation in that range is also continuous. Limestone, crushed to minus 5/16 size, is heated, discharged, and recycled at a maximum average rate of 250 lb/min while aluminum oxide or silicon carbide, No. 8 grit, is circulated at rates up to 167 lb/min. The FBSH control system is designed for automatic operation, and capability is included for external computerized data acquisition and/or supervisory control. An operating and maintenance manual and as-built drawings have been submitted. This report describes the FBSH equipment, its design basis, and its operation. It has been prepared and submitted in fulfillment of Contract Number DIAC05-77ET10499.

    The goal of this project was to develop chaos analysis and neural network-based modeling techniques and apply them to the pressure-drop data obtained from the Fluid Bed Combustion (FBC) system (a small scale prototype model) located at the Federal Energy Technology Center (FETC)-Morgantown. The second goal was to develop neural network-based chaos control techniques and provide a suggestive prototype for possible real-time application to the FBC system. The experimental pressure data were collected from a cold FBC experimental set-up at the Morgantown Center. We have performed several analysis on these data in order to unveil their dynamical and chaotic characteristics. The phase-space attractors were constructed from the one dimensional time series data, using the time-delay embedding method, for both normal and abnormal conditions. Several identifying parameters were also computed from these attractors such as the correlation dimension, the Kolmogorov entropy, and the Lyapunov exponents. These chaotic attractor parameters can be used to discriminate between the normal and abnormal operating conditions of the FBC system. It was found that, the abnormal data has higher correlation dimension, larger Kolmogorov entropy and larger positive Lyapunov exponents as compared to the normal data. Chaotic system control using neural network based techniques were also investigated and compared to conventional chaotic system control techniques. Both types of chaotic system control techniques were applied to some typical chaotic systems such as the logistic, the Henon, and the Lorenz systems. A prototype model for real-time implementation of these techniques has been suggested to control the FBC system. These models can be implemented for real-time control in a next phase of the project after obtaining further measurements from the experimental model. After testing the control algorithms developed for the FBC model, the next step is to implement them on hardware and link them to

    We investigated the effect of leaf age on the response of net photosynthesis (A), stomatal conductance (g{sub wv}), foliar injury, and leaf nitrogen concentration (N{sub L}) to tropospheric ozone (O{sub 3}) on Prunus serotina seedlings grown in open-plots (AA) and open-top chambers, supplied with either carbon-filtered or non-filtered air. We found significant variation in A, g{sub wv}, foliar injury, and N{sub L} (P < 0.05) among O{sub 3} treatments. Seedlings in AA showed the highest A and g{sub wv} due to relatively low vapor pressure deficit (VPD). Older leaves showed significantly lower A, g{sub wv}, N{sub L}, and higher foliar injury (P < 0.001) than younger leaves. Leaf age affected the response of A, g{sub wv}, and foliar injury to O{sub 3}. Both VPD and N{sub L} had a strong influence on leaf gas exchange. Foliar O{sub 3}-induced injury appeared when cumulative O{sub 3} uptake reached 8-12 mmol m{sup -2}, depending on soil water availability. The mechanistic assessment of O{sub 3}-induced injury is a valuable approach for a biologically relevant O{sub 3} risk assessment for forest trees. - Ozone effects on symptom development and leaf gas exchange interacted with leaf age and N-content on black cherry seedlings.

    An isolate of P. acidilactici capable of producing vanillin from rice bran was isolated from a milk product. Response Surface Methodology was employed for statistical media and process optimization for production of biovanillin. Statistical medium optimization was done in two steps involving Placket Burman Design and Central Composite Response Designs. The RSM optimized vanillin production medium consisted of 15% (w/v) rice bran, 0.5% (w/v) peptone, 0.1% (w/v) ammonium nitrate, 0.005% (w/v) ferulic acid, 0.005% (w/v) magnesium sulphate, and 0.1% (v/v) tween-80, pH 5.6, at a temperature of 37 degrees C under shaking conditions at 180 rpm. 1.269 g/L vanillin was obtained within 24 h of incubation in optimized culture medium. This is the first report indicating such a high vanillin yield obtained during biotransformation of ferulic acid to vanillin using a Pediococcal isolate.

    The enzymatic hydrolysis of Pennisetum purpureum (elephant grass) was evaluated at high total solid levels (from 4% to 20% (w/v)) in a concomitant ball milling treatment in a rotating hydrolysis reactor (RHR). The greatest glucose yield was 20.17% when 4% (w/v) untreated biomass was employed. When sugars obtained from enzymatic hydrolysis were submitted to fermentation with Saccharomyces cerevisiae, the greatest ethanol yield was 22.61% when 4% (w/v) untreated biomass was employed; however, the highest glucose concentration (12.47g/L) was obtaining using 20% (w/v) solids and highest ethanol concentration (6.1g/L) was obtained using 16% (w/v) solids. When elephant grass was hydrolyzed in the rotating hydrolysis reactor, ethanol production was about double that was produced when the biomass was hydrolyzed in a static reactor (SR). These data indicate that it is possible to produce ethanol from elephant grass when milling treatment and enzymatic hydrolysis are performed at the same time. Copyright © 2016.

    Full Text Available The in vitro prebiotic activity of galactooligosaccharides (GOS and low-molecular-weight carbohydrates (LMWC extracted from lupin and squash seeds on the growth of Lactobacillus paracasei BGP1 was studied. To this end, the change in cell density after 24 h of L. paracasei growth on 1% (w/v glucose, 1% (w/v raffinose, 1% (w/v commercial inulin GR, 1% (w/v lupin extract, and 1% (w/v squash extract relative to the change in cell density of a mixture of enteric strains under the same culture conditions were evaluated. Additionally, the principal components of GOS and LMWC in the extracts were identified using Thin Layer Chromatography. The highest prebiotic activity score was for L. paracasei grown on squash extract (0.55±0.03, followed by lupin extract (0.49±0.02, inulin (0.38±0.05 and raffinose (0.37±0.05. These results will contribute to selecting plant species as potential sources of prebiotic ingredients for the development of functional foods.

    Full Text Available Sludge oil contains 30%–50% hydrocarbon fractions that comprise saturated fractions, aromatics, resins, and asphaltene. Asphaltene fraction is the most persistent fraction. In this research, the indigenous bacteria that can degrade asphaltene fractions from a sludge oil sample from Balikpapan that was isolated using BHMS medium (Bushnell-Hass Mineral Salt with 0.01% (w/v yeast extract, 2% (w/v asphaltene extract, and 2% (w/v sludge oil. The ability of the four isolates to degrade asphaltene fractions was conducted by the biodegradation asphaltene fractions test using liquid cultures in a BHMS medium with 0.01% (w/v yeast extract and 2% (w/v asphaltene extract as a carbon source. The parameters measured during the process of biodegradation of asphaltene fractions include the quantification of Total Petroleum Hydrocarbon (g, log total number of bacteria (CFU/ml, and pH. There are four bacteria (isolates 1, 2, 3, and 4 that have been characterized to degrade asphaltic fraction and have been identified as Bacillus sp. Lysinibacillus fusiformes, Acinetobacter sp., and Mycobacterium sp., respectively. The results showed that the highest ability to degrade asphaltene fractions is that of Bacillus sp. (isolate 1 and Lysinibacillus fusiformes (Isolate 2, with biodegradation percentages of asphaltene fractions being 50% and 55%, respectively, and growth rate at the exponential phase is 7.17x107 CFU/mL.days and 4.21x107 CFU/mL.days, respectively.

    Lilium longiflorum Overig is a Lilaceous plant grown for ornamental as well as certain other general purposes. The research presented here focuses on the method of protoplast isolation from the In vitro grown callus of Lilium longiflorum Overig. Series of experiments were conducted in order to optimize the conditions. Four different amounts of callus and a range of incubation time were used to achieve maximum number of viable protoplasts. However, the calli used were treated with Enzyme solution containing 0.5 percentage (w/v) Macerozyme, 2 percentage (w/v) Cellulase and 0.1 percentage (w/v) Pectinase in combination, to obtain maximum number of viable protoplasts through the process of cell-wall digestion. Furthermore, an osmoticum of 20 percentage (w/v) sucrose and a washing solution consisting of 0.1 percentage (w/v) MES and 0.5M Mannitol were added to suspend a ring of protoplast at the interphase of both the solutions. This ring of protoplast was then isolated and tested for viability and yield. Consequently, amongst the various sets of experiment, callus of 1.5 grams and incubation time of 4 hours was found an ideal approach to obtain maximum number of viable protoplasts. (author)

    The sugar composition of the unfermented sap from oil palm (Elaeis guinensis) trees growing in the plantations of the Nigerian Institute for Oil Palm Research, Benin City, has been determined. While sucrose concentration ranges from 9.59 to 10.59% (w/v) in the pure unfermented sap, that of either glucose or fructose is much less than 1% (w/v) (0.13-0.73% w/v). Raffinose occurs in traces only (0.13-0.35 w/v). These results were derived from our improved methods which eliminate completely, or reduce to a bare minimum, fermentation of the sap during collection. The variation with time of storage of the individual sugars in the sap during fermentation to form palm wine reveals that, as sucrose steadily decreases, fructose reaches a peak at 1.51% (w/v) at the 9th hour, and thereafter declines, while glucose and raffinose remain continuously low; all sugars disappear beyond the 33rd hour. Concomittantly, pH decreases from pH 6.60 at zero time and stabilizes at pH 3.30 after 48 h, while titrable acidity increases continuously up until the 96th hour. These changes account for the variations in the quality of palm wine during storages.

    Full Text Available The WorldView-3 (WV-3 satellite is a new sensor with high spectral resolution, which equips eight multispectral bands in the visible and near-infrared (VNIR and additional eight bands in the shortwave infrared (SWIR. In order to meet the requirements of large-scale geological mapping, this paper assessed WV-3 data for lithological mapping in comparison with Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER and Operational Land Imager (OLI/Landsat-8 data. The study area is located in the Pobei area of the Xinjiang Uygur Autonomous Region, where bedrock outcrops are widely distributed. The whole experiment was divided into six steps: data pre-processing, visual interpretation of various lithological units, samples procedure, lithological mapping by a support vector machine algorithm (SVM, accuracy evaluation, and assessment. The results showed that the classification accuracy of WV-3 data was 87%, which kept 17% higher than that of ASTER data, 14% higher than that of OLI/Landsat-8 data, indicated that WV-3 data contained more diagnostic absorption features mainly thanks to its SWIR bands, and benefited by its high spatial resolution, as well. However, it also confirmed that there were some considerable flaws, such as the confusing identification of biotite-quartz schist. Overall, the WV-3 data is still the most promising data for geological applications currently.

    Two kinds of exoglucanase were purified from a marine Aspergillus niger. Catalytic ability of halophilic exoglucanase with a lower molecular weight and secondary structure change was analyzed at different salinities. Activity of the low molecular weight exoglucanase in 10% NaCl solution (w/v) was 1.69-fold higher of that in NaCl-free solution. Half-life time in 10% NaCl solution (w/v) was over 1.27-fold longer of that in NaCl-free solution. Free energy change of the low molecular weight exoglucanase denaturation, △G, in 10% NaCl solution (w/v) was 0.54 kJ/mol more than that in NaCl-free solution. Melt point in 10% NaCl solution (w/v), 52.01 °C, was 4.21 °C higher than that in NaCl-free solution, 47.80 °C. K m value, 0.179 mg/ml in 10% NaCl solution (w/v) was less 0.044 mg/ml than that, 0.224 mg/ml, in NaCl-free solution. High salinity made content of α-helix increased. Secondary structure change caused by high salinities improved exoglucanase thermostability and catalysis activity. The halophilic exoglucanase from a marine A. niger was valuable for hydrolyzing cellulose at high salinities.

    When young adult female W/Wv mice are given 0.5 micro+Ci 89 Sr/g body weight intravenously, their hematocrit values oscillate from nadirs of 26% to zeniths of 42% with a periodicity of 16 days. The response of the W/Wv mouse to an assortment of radioactive and hematologic stresses have been examined in an effort to understand better the pathophysiology of cyclic erythropoiesis. When the dose of 89 Sr is increased, the amplitude of cycling increases as nadirs are lowered, but periodicity is unchanged. When the dose of 89 Sr is lowered to 0.3 microCi or less, cyclic erythropoiesis of substantial amplitude is observed only after five or six microoscillations. A single hematopoietic insult of 80 rad x-irradiation coupled with phlebotomy produces a transient form of cyclic erythropoiesis, namely, a series of dampened oscillations prior to recovery. Finally, we report that Wv/Wv mice exhibit a form of cyclic erythropoiesis in response to 0.5 microCi 89 Sr/g body weight, in which the hematocrit values of successive nadirs gradually increase, and stabilize at about 100 days. 89 Sr does not induce cyclic erythropoiesis in the +/+, W/+, or W/v/+ mice, the Hertwig strain of anemic mice, or in normal BDF1 mice

    To determine whether race/ethnicity and socioeconomic status are associated with amyotrophic lateral sclerosis (ALS) mortality in the United States. The National Longitudinal Mortality Study (NLMS), a United States-representative, multistage sample, collected race/ethnicity and socioeconomic data prospectively. Mortality information was obtained by matching NLMS records to the National Death Index (1979-2011). More than 2 million persons (n = 1,145,368 women, n = 1,011,172 men) were included, with 33,024,881 person-years of follow-up (1,299 ALS deaths , response rate 96%). Race/ethnicity was by self-report in 4 categories. Hazard ratios (HRs) for ALS mortality were calculated for race/ethnicity and socioeconomic status separately and in mutually adjusted models. Minority vs white race/ethnicity predicted lower ALS mortality in models adjusted for socioeconomic status, type of health insurance, and birthplace (non-Hispanic black, HR 0.61, 95% confidence interval [CI] 0.48-0.78; Hispanic, HR 0.64, 95% CI 0.46-0.88; other races, non-Hispanic, HR 0.52, 95% CI 0.31-0.86). Higher educational attainment compared with socioeconomic status, birthplace, or type of health insurance. Higher rate of ALS among whites likely reflects actual higher risk of ALS rather than ascertainment bias or effects of socioeconomic status on ALS risk. © 2016 American Academy of Neurology.

    Background Circular migration and injection drug use increase the risk of HIV transmission in sending communities. We describe female sex workers who are injection drug users’ (FSW-IDUs) circular migration and drug use behaviors. Methods Between 2008-2010, 258 migrant FSW-IDUs residing in Tijuana and Ciudad Juarez, Mexico responded to questionnaires. Results 24% of FSW-IDUs were circular migrants. HIV prevalence was 3.3% in circular migrants and 6.1% in non-circular migrants; 50% of circular and 82% of non-circular migrants were unaware of their HIV infection. Among circular migrants, 44% (n=27) consumed illicit drugs in their birthplace; 70% of these (n=20) injected drugs and one-half of injectors shared injection equipment in their birthplace. Women reporting active social relationships were significantly more likely to return home. Discussion Circular migrant FSW-IDUs exhibit multiple HIV risks and opportunities for bridging populations. Regular HIV testing and treatment and access to substance use services is critical for FSW-IDUs and their sexual/drug-using contacts. PMID:21833727

    The ingestion toxicity of three Lamiaceae essential oils (EOs) - Hyptis suaveolens, Rosmarinus officinalis and Lavandula angustifolia - incorporated in protein baits was evaluated against Bactrocera oleae, a worldwide pest of olive fruits. In laboratory conditions, all the tested EOs showed dose-dependent toxicity on B. oleae, with mortality rates ranging from 12% (EO concentration: 0.01% w:v) to 100% (EO concentration: 1.75% w:v). Semi-field results highlighted the toxicity of L. angustifolia and H. suaveolens EOs, which exerted more than 60% of flies mortality at a concentration of 1.75% (w:v). Gas Chromatography-Electron Impact Mass Spectrometry analyses of the three EOs showed that H. suaveolens EO was dominated by monoterpene and sesquiterpene hydrocarbons. Oxygenated monoterpenes were the main chemical class in R. officinalis and L. angustifolia EOs. Further research is needed to evaluate the efficacy of these EOs plus food bait against the olive fruit fly in the open field.

    In this work, methanol in crude glycerol solution was used to assist the lipid production with oleaginous yeast Trichosporon oleaginosus cultivated under non-sterilized conditions. The investigated methanol concentration was 0%, 1.4%, 2.2%, 3.3% and 4.4% (w/v). The results showed that methanol played a significant role in the non-sterilized fermentation for lipid production. The optimal methanol concentration was around 1.4% (w/v) in which the growth of T. oleaginosus was promoted and overcame that of the contaminants. The non-sterilized fed-batch fermentation with initial methanol concentration of 1.4% (w/v) was then performed and high biomass production (43.39 g/L) and lipid production (20.42 g/L) were achieved.

    Guava pulp used for ethanol production by three yeast strains contained 10% (w/v) total sugars and was pH 4.1. Ethanol production at the optimum sugar concentration of 10%, at pH 4.1 and 30{sup o}C was 1.5%, 3.6% and 3.9% (w/v) by Saccharomyces cerevisiae MTCC 1972, Isolate-1 and Isolate-2, respectively, at 60 h fermentation. Higher sugar concentrations at 15 and 20% were inhibitory for ethanol production by all test cultures. The maximum production of ethanol at optimum natural sugar concentration (10%) of guava pulp, was 5.8% (w/v) at pH 5.0 by Isolate-2 over 36 h fermentation, which was only slightly more than the quantity of ethanol produced by Saccharomyces cerevisiae (5.0%) and Isolate-1 (5.3%) over 36 and 60 h fermentation, respectively.

    Full Text Available The aim of the present work was to study the influence of multiple bioprocess parameters for the maximum production of lipase from Pseudomonas sp. BWS-5. The culture reached the stationary phase of growth after 36h of incubation when the maximum lipase production was obtained at flask level. The different media components such as carbon sources, nitrogen sources, trace elements and process parameters such as the pH of the medium, temperature and time of incubation, agitation/stationary conditions, etc. were optimized at flask level and at bioreactor level. The maximum enzyme production of 298 IU/mL was obtained with the use of simple medium with pH 6.5 containing glucose (1 %, w/v, peptone (3 %, w/v and KCl (0.05 %, w/v after 30h of incubation at 37°C under agitation (200 rpm conditions with 0.75 vvm of air supply.

    Full Text Available Very often hydrochloric acid is employed in acidification operations aiming to dissolve the mineral matrix in petroleum wheel operations, which always require intense use of corrosion inhibitors. This work presents an evaluation of common indicators, phenolfthaleine, fluorescein, methylene blue, alizarine S and methyl orange, as corrosion inhibitors for carbon steel in HCl 15% w/v at temperatures of 26, 40 and 60 ºC. Fluorescein and methyl orange show excelent corrosion inhibition efficiencies at 26 ºC; however at 60 ºC only fluorescein shows good corrosion inhibition when employed with alcohol and/or formaldehyde. For the fluorescein 1% w/v + formaldehyde 0.6% w/v mixture we present polarization and impedance curves and adsorption isotherms.

    The aim of this work is to investigate biological leaching of rare earth elements (REEs) and radioactive elements from red mud, and to evaluate the radioactivity of the bioleached red mud used for construction materials. A filamentous, acid-producing fungi named RM-10, identified as Penicillium tricolor, is isolated from red mud. In our bioleaching experiments by using RM-10, a total concentration of 2% (w/v) red mud under one-step bioleaching process was generally found to give the maximum leaching ratios of the REEs and radioactive elements. However, the highest extraction yields are achieved under two-step bioleaching process at 10% (w/v) pulp density. At pulp densities of 2% and 5% (w/v), red mud processed under both one- and two-step bioleaching can meet the radioactivity regulations in China. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Ethanol production from steam explosion alkaline delignified bagasse was investigated by saccharification and simultaneous fermentation. Non delignified bagasse (ND) contained 25% lignin, and after alkaline delignification, materials with 6% (D1 - NaOH 1% w/v) and 12% (D05 - NaOH 0.5% w/v) lignin, respectively, were obtained. Ethanol production increased 450% and 733% in relation to ND, when D05 and D1 material, respectively, were used. Higher productivity and EtOH/bagasse were observed for D1. However, higher enzymatic convertibility of cellulose was obtained with 0.5% w/v NaOH. Alkaline delignification increased the ethanol production despite decreased cellulose.

    Full Text Available The umbu is the umbuzeiro fruit (Spondias tuberosa Arr. Cam. which is a tree native of the Brazilian backlands. The aim of this work was to evaluate the physical and chemical properties of commercial and concentrated umbu pulp to be used as raw material in the production of structured. The commercial pulp (2.5 kg was acquired in the trade of Feira de Santana. The concentration of the evaporator route pulp vacuo to increase the soluble solids content of 8.5ºBrix to 15.5ºBrix It was held in the Food Chemistry Laboratory of the State University of Feira de Santana. It was obtained after concentrating a yield of 41.12% by mass of fruit pulp. The concentration process had no influence in the nutritional value of umbu pulp. The concentrated pulp had the following properties pH (2.43, soluble solids (15.5°Brix, acidity (3.11 g citric acid/100 g, total protein (1.28% - w/v, vitamin C (4.36 mg/100 g - w/v, reducing sugars (6.08% - w/v, total sugars (13.55% - w/v non reducing sugars (7.46% - w/v and ash (0.42% - w/v. The physicochemical characteristics of commercial umbu pulps had similar pH, Total Soluble Solids, acidity, proteins and ashes; higher values of reducing sugars and non-reducing and a lower vitamin C content that the pulps reported in the literature. The concentration process produced an increase in Total Soluble Solids, proteins, acidity, reducing and non reducing sugars and ash content. However there was a decrease in vitamin C concentration of the pulp.

    Although cassava (Manihot esculenta Crantz) is a potential bioethanol crop, high operational costs resulted in a negative energy balance in the earlier processes. The present study aimed at optimizing the bioethanol production from cassava starch using new enzymes like Spezyme {sup registered} Xtra and Stargen trademark 001. The liquefying enzyme Spezyme was optimally active at 90 C and pH 5.5 on a 10% (w/v) starch slurry at levels of 20.0 mg (280 Amylase Activity Units) for 30 min. Stargen levels of 100 mg (45.6 Granular Starch Hydrolyzing Units) were sufficient to almost completely hydrolyze 10% (w/v) starch at room temperature (30 {+-} 1 C). Ethanol yield and fermentation efficiency were very high (533 g/kg and 94.0% respectively) in the Stargen + yeast process with 10% (w/v) starch for 48 h. Raising Spezyme and Stargen levels to 560 AAU and 91.2 GSHU respectively for a two step loading [initial 20% (w/v) followed by 20% starch after Spezyme thinning]/initial higher loading of starch (40% w/v) resulted in poor fermentation efficiency. Upscaling experiments using 1.0 kg starch showed that Stargen to starch ratio of 1:100 (w/w) could yield around 558 g ethanol/kg starch, with a high fermentation efficiency of 98.4%. The study showed that Spezyme level beyond 20.0 mg for a 10% (w/v) starch slurry was not critical for optimizing bioethanol yield from cassava starch, although an initial thinning of starch for 30 min by Spezyme facilitated rapid saccharification-fermentation by Stargen + yeast system. The specific advantage of the new process was that the reaction could be completed within 48.5 h at 30 {+-} 1 C. (author)

    Full Text Available In order to improve the quality of the Mediterranean high-impact weather (HIW numerical predictions, this study proposes to modify the potential vorticity (PV field of the model initial state, taking advantage of information provided by the water vapour (WV channel of the METEOSAT-7 satellite. The implemented PV field modifications aim to reduce the mismatch between the upper-level PV features and the WV brightness temperatures guided by the known relation between these two fields (PV-WV technique. The PV-WV technique effectiveness is evaluated on two HIW events, and is also compared with two additional PV modification techniques from an earlier study. The chosen episodes occurred on 9–10 June 2000 and 9–10 October 2002 and produced heavy precipitation over both Spain and France. The main difference between these two episodes is found in the driving mechanism, a mesoscale cyclone for the June 2000 event and a larger low-pressure centre for the October 2002 case. The two additional PV modification techniques introduce perturbations along the zones highlighted by the MM5 adjoint model calculated sensitivity zones (PV-adjoint and along the three-dimensional PV structure presenting the locally most intense values and gradients of the field (PV-gradient. A close examination of both case studies of the forecast rainfall fields and several objective verification indices show that the PV-WV technique performance exceeds the control (or non-perturbed forecast skill while remaining inside the distribution obtained by both PV-gradient and PV-adjoint techniques. This PV-WV technique could be used to increase the ensemble spread introducing higher amplitude modifications. Thus, a more skilled ensemble prediction system could be built by taking advantage of the subjectivity inherent to this method (manual perturbations and also of the uncertainty present in the initial state.

    Escherichia coli K-12 was exposed to Quillaja saponaria saponins from various commercial firms (Sigma, Roth and Nor-feed) and to an extract of Yucca schidigera plant powder (DK Sarsaponin 30) at different concentrations (0.05-1.0% w/v). A concentration-dependent response was observed. Quillaja saponaria saponins from Sigma increased growth up to 0.1% (w/v) level, whereas Nor-feed and Roth saponins produced maximum growth at a much higher level (0.5 and 0.75%, w/v, respectively). These results suggest that quillaja saponins from various sources differ in their biological activity, although all three saponins had the same content of vanillin-sulphuric acid reactive moieties. The lyophilized water extract from the DK Sarsaponin powder showed maximum growth at 0.1% (w/v) level. The levels at which maximum growth was observed did not change on subjecting the quillaja or yucca saponins to heat treatment in an autoclave (121 degrees C for 30 min). All the saponins and the plant extract increased growth of Escherichia coli up to a certain concentration and thereafter decreased growth. In spite of the decreased growth at higher levels of saponins, it was higher compared to the control (without saponin) up to levels of 1% (w/v) for all saponins except Quillaja saponins from Sigma, for which the growth was lower at levels of 0.25% (w/v) and higher. Saponins have the potential to modulate microbial growth in natural and artificial fermenters.

    Full Text Available Pine wilt disease is caused by the pine wood nematode (Bursaphelenchus xylophilus and Japanese pine sawyer (Monochamus alternatus. This study attempted to detect damaged pine trees at different levels using a combination of airborne laser scanning (ALS data and high-resolution space-borne images. A canopy height model with a resolution of 50 cm derived from the ALS data was used for the delineation of tree crowns using the Individual Tree Detection method. Two pan-sharpened images were established using the ortho-rectified images. Next, we analyzed two kinds of intensity-hue-saturation (IHS images and 18 remote sensing indices (RSI derived from the pan-sharpened images. The mean and standard deviation of the 2 IHS images, 18 RSI, and 8 bands of the WV-2 and WV-3 images were extracted for each tree crown and were used to classify tree crowns using a support vector machine classifier. Individual tree crowns were assigned to one of nine classes: bare ground, Larix kaempferi, Cryptomeria japonica, Chamaecyparis obtusa, broadleaved trees, healthy pines, and damaged pines at slight, moderate, and heavy levels. The accuracy of the classifications using the WV-2 images ranged from 76.5 to 99.6 %, with an overall accuracy of 98.5 %. However, the accuracy of the classifications using the WV-3 images ranged from 40.4 to 95.4 %, with an overall accuracy of 72 %, which suggests poorer accuracy compared to those classes derived from the WV-2 images. This is because the WV-3 images were acquired in October 2016 from an area with low sun, at a low altitude.

    Campylobacteriosis is the most common foodborne bacterial infection in developed countries and many cases are associated with poultry. This study investigated the immediate and storage effect of dipping inoculated poultry skin samples in trisodium phosphate (TSP, 10 & 14%, w/v), lactic acid (LA, 1 & 5%, v/v), citric acid (CA, 1 & 5%, w/v), peroxyacids (POA, 100 & 200 ppm) and acidified sodium chlorite (ASC, 500 & 1200 ppm). Spray application was also tested using the higher concentrations in the laboratory. In a broiler processing plant the efficacy of using TSP (14%) and CA (5%) applied by immersion and spray was investigated using naturally contaminated carcasses and the effect of these treatments on the sensory attributes of a skin-on (drumstick) and skin-off (fillet) raw and cooked product was assessed using descriptive sensory analysis. In the laboratory, immersion in TSP (14%), LA (5%), CA (5%) and ASC (1200 ppm) significantly (Ppoultry meat. Spraying was ineffective even after storage. In the broiler processing plant, immersion in TSP (14%) or CA (5%) achieved Campylobacter reductions of 2.49 and 1.44 log10 cfu/cm(2), respectively. There were no significant differences between the treatments for any of the attributes measured in either raw or cooked drumsticks. The 'colour' of raw chicken fillets treated with both TSP (14%, w/v) and CA (5%, w/v) was significantly (P≤0.05) lighter than that of control samples. The 'intensity of chicken odour' and the perception of 'salt' in cooked chicken fillets treated with CA (5%, w/v) were also significantly (P≤0.05) higher than that of either control or TSP (14%, w/v) treated samples. It was concluded that TSP (14%) or CA (5%) could be applied to significantly reduce Campylobacter contamination of broilers without adversely affecting the sensory quality of the product. © 2013.

In this paper, we present the results of WV and O3 intercomparisons that have been performed as part of the SPARC (Stratosphere–troposphere Processes and their Role in Climate Reanalysis Intercomparison Project (S-RIP. The comparisons cover a range of timescales and evaluate both inter-reanalysis and observation-reanalysis differences. We also provide a systematic documentation of the treatment of WV and O3 in current reanalyses to aid future research and guide the interpretation of differences amongst reanalysis fields.The assimilation of total column ozone (TCO observations in newer reanalyses results in realistic representations of TCO in reanalyses except when data coverage is lacking, such as during polar night. The vertical distribution of ozone is also relatively well represented in the stratosphere in reanalyses, particularly given the relatively weak constraints on ozone vertical structure provided by most assimilated observations and the simplistic representations of ozone photochemical processes in most of the reanalysis forecast models. However, significant biases in the vertical distribution of ozone are found in the upper troposphere and lower stratosphere in all reanalyses.In contrast to O3, reanalysis estimates of stratospheric WV are not directly constrained by assimilated data. Observations of atmospheric humidity are typically used only in the troposphere, below a specified vertical level at or near the tropopause.

    Alessandrini and Krzywicki's (AK's) approximation to Weingarten and Velikson's (WV's) disordered coupling, non-hermitian fermion model is analysed and found to exhibit doubling. Thus the non-hermitian regular lattice model of Alonso and Cortes must also be discarded. We show that in the general hon-hermitian regular lattice case there are extra zero modes and that in two dimensions the net chirality is zero. A better approximation of WV's model allows for the possibility of spontaneous chiral symmetry breaking of the doubled fermions in that model as in the random lattice case. (orig.)

However, pineapple waste media contain very little nitrogen (0.003-0.015% w/v. Various nitrogen sources were incorporate and their effects on biomass, yield and productivity were studied. Significant (p<0.05 increment on biomass production was observed when nitrogen supplement (commercial yeast extract, peptone, ammonium dihydrogen phosphate, ammonium sulphate and potassium nitrate was added into fermentation medium. Commercial yeast extract, Maxarome® which increased 55.2% of biomass production at 0.09% (w/v nitrogen content, is the most suitable among the selected organic source. On the other hand, ammonium dihydrogen phosphate at 0.09% (w/v nitrogen content is comparable inorganic source which enhanced 53.7% of production. Total nitrogen content of each treatment at 0.05% (w/v showed that nitrogen supplied was not fully utilized as substrate limitation in the fermentation medium.

    The Indian red jungle fowl is a sub-species of the genus Gallus native to South Asia; facing high risk of extinction in its native habitat. During cryopreservation, permeable cryoprotectants like glycerol are usually employed and we previously showed encouraging results with 20% glycerol. Because bird spermatozoa contain very little intracellular water, the possibility of replacing an internal cryoprotectant by an external one is opened. In the present study, we tested the replacement of internal cryoprotectant glycerol by the external cryoprotectant Polyvinylpyrrolidone (PVP). PVP is a non-permeable cryoprotectant and keeps the sperm in glassy state both in cooling and warming stages without making ice crystallization within the sperm cell. We evaluated the effect of various levels of polyvinylpyrrolidone (PVP) on Indian red jungle fowl semen quality and fertility outcomes. The qualifying semen ejaculates collected from eight mature cocks were pooled, divided into five aliquots, diluted (37 °C) with red fowl semen extender having PVP [0% (control) 4% (w/v), 6% (w/v), 8% (w/v) and 10% (w/v)]. Diluted semen was cryopreserved and stored in liquid nitrogen. The whole experiment was repeated/replicated for five times independently. Sperm motility, plasma membrane integrity, viability and acrosome integrity were recorded highest (P jungle fowl spermatozoa than glycerol and can be used in routine practice avoiding the contraceptive effects of glycerol.

    The aim of this study was to evaluate the combined effect of temperature (10, 20 and 37°C), pH (4, 5, 6, 7 and 8), and NaCl content (0, 1, 3, 4, 5 and 6% w/v) on the growth and putrescine and cadaverine production of Serratia marcescens CCM 303 under model conditions. The decarboxylase activity of S. marcescens was monitored in broth after cultivation. The cultivation medium was enriched with selected amino acids (ornithine, arginine and lysine; 0.2% w/v each) serving as precursors of biogenic amines. Levels of putrescine and cadaverine in broth were analysed by high-performance liquid chromatography after pre-column derivatisation with o-phthalaldehyde reagent. S. marcescens produced higher amounts of putrescine (up to 2096.8 mg L(-1)) compared to cadaverine content (up to 343.3 mg L(-1)) in all cultivation media. The highest putrescine and cadaverine concentrations were reached during cultivation at 10-20°C, pH 5-7 and NaCl content 1-3% w/v. On the other hand, the highest BAs production of individual cell (recalculated based on a cell; so called "yield factor") was observed at 10°C, pH 4 and salt concentration 3-5% w/v as a response to environmental stress.

    Plant species invasion is known to be a major threat to socioeconomic and ecological systems. Due to high cost and limited extents of urban green spaces, high mapping accuracy is necessary to optimize the management of such spaces. We compare the performance of the new-generation WorldView-2 (WV-2) and SPOT-5 images in mapping the bracken fern [Pteridium aquilinum (L) kuhn] in a conserved urban landscape. Using the random forest algorithm, grid-search approaches based on out-of-bag estimate error were used to determine the optimal ntree and mtry combinations. The variable importance and backward feature elimination techniques were further used to determine the influence of the image bands on mapping accuracy. Additionally, the value of the commonly used vegetation indices in enhancing the classification accuracy was tested on the better performing image data. Results show that the performance of the new WV-2 bands was better than that of the traditional bands. Overall classification accuracies of 84.72 and 72.22% were achieved for the WV-2 and SPOT images, respectively. Use of selected indices from the WV-2 bands increased the overall classification accuracy to 91.67%. The findings in this study show the suitability of the new generation in mapping the bracken fern within the often vulnerable urban natural vegetation cover types.

    Volatile chemicals are a group of very important compounds in natural products. Curcuma rhizome, which contains many bioactive volatile compounds, is a traditional Chinese medicine that has long been used for the treatment of several diseases. In the present study, a microemulsion electrokinetic chromatography (MEEKC) method was developed for the analysis of four volatile components in Curcuma rhizome, including germacrone, furanodiene, curcumenol and curdione. Experimental parameters, including the pH, type and concentrations of background electrolyte, and microemulsion compositions (type and concentrations of surfactant, co-surfactant and oil phase) were intensively investigated. Finally, the primary compounds in the methanol extract of Curcuma rhizome were separated within 30 min using a running buffer composed of 2.31% w/v (80 mmol/L) sodium dodecyl sulfate (SDS), 0.91% w/v (80 mmol/L) 1-octane, 6.95% w/v (937.5 mmol/L) 1-butanol and 1.88% w/v (312.5 mmol/L) propanol in a 5-mM borate buffer (pH 8.1). The contents of the four investigated compounds were determined in the rhizome from C. phaeocaulis. The results showed that the developed MEEKC method provided an alternative tool for the analysis of volatile components, especially those of heat-sensitive compounds from natural products.

    Alginate-coated Lactobacillus acidophilus LA5 or Lactobacillus casei 01 was recoated with either 0.1-0.5% (w/v) alginate or 0.05-0.15% (w/v) poly-L-lysine (PLL) plus 0.2% (w/v) alginate or 5-15% (w/v) gelatin, after which they were determined for survivability in gastric or bile longan juices. The morphology of encapsulated probiotic cells illustrated that recoated beads with 0.5% alginate showed a more compact surface and a greater protective effect than other recoating materials. The recoated beads with 0.5% alginate and 0.05-0.15% PLL plus 0.2% alginate of both strains showed the highest viability in gastric longan juice. In bile longan juice, only 0.5% alginate showed the best protection for both recoated beads. When considering the storage stability, encapsulated L. acidophilus LA5 exhibited a higher viable count than those of the free cells, whereas L. casei 01 showed equivalent viability of both free and double-coated cells. Based on the impact of pressurization or pasteurization, both processed juices gave rise to equivalent survivability of the probiotic cells during storage.

    Conventional topical delivery in hyperacute bacterial conjunctivitis and endophthalmitis is associated with low drug bioavailability due to rapid precorneal clearance. Hence, in the present investigation, an attempt has been made to enhance ocular bioavailability of tobramycin sulfate by formulating drug-loaded microparticles dispersed in thermosensitive in situ gel. Microparticles prepared by emulsion-ionic gelation technique were characterized for drug loading, entrapment efficiency, particle size, surface morphology, and in vitro drug release. Consequently microparticles (F2 prepared with 1.5%w/v chitosan, 0.2%w/v tripolyphosphate, and drug, 30%w/w of polymer) with high drug loading and encapsulation efficiency were dispersed in thermosensitive in situ gel containing poloxamer 407 and varying percentage of chitosan. In situ gel containing drug-loaded microparticles were evaluated for gelation temperature, rheological behavior, mucoadhesive strength, in vitro drug release, in vitro permeation, ocular irritation, and bioavailability in aqueous humor of rabbits. Formulation containing 17%w/v poloxamer 407 and 0.5%w/v chitosan (P2) gelled at 32°C ± 1.5°C gave pseudoplastic behavior. In vitro permeability of tobramycin from the formulation P2 was found 2-folds greater than eye drops. It also gave significantly higher aqueous humor concentration of tobramycin compared with eye drops with no signs of ocular irritation. Thus, the formulation possesses high potential for treating ocular infections.

    Corn steep liquor (CSL) has been used as a nutrition adjunct for the production of an extracellular lipase from Aspergillus niger, which has immense importance as an additive in laundry detergent formulations. A five-level four-factorial central composite design was chosen to determine the optimal medium components with four critical variables, namely, CSL, NH4H2PO4, Na2HPO4, and sesame oil, that were found to be influential for lipase production by the classical one-factor-at-a-time method. The model suggested that all of the factors chosen had a significant impact on lipase production, and the optimum values of the influential parameters were CSL, 2.0%, w/v; NH4H2PO4, 0.05%, w/v; Na2HPO4, 0.75%, w/v; and sesame oil, 2.0%, w/v, with an activity of 26.7 U/mL at 48 h and 30 degrees C, which was 2.16-fold higher than the initial activity (12 U/mL) obtained by the conventional one-factor-at-a-time method. Furthermore, the enzyme has good potential for the hydrolysis of vegetable oils and fish oils, and a hydrolytic ratio of 88.73% was obtained with palm oil at 48 h. The utilization of CSL and sesame oil for lipase production from A. niger makes the process green, because both are renewable substrates and economically viable at an industrial scale.

    Inoculation of starter culture in cocoa bean fermentation produces consistent, predictable and high quality of fermented cocoa beans. It is important to produce healthy inoculum in cocoa bean fermentation for better fermented products. Inoculum could minimize the length of the lag phase in fermentation. The purpose of this study was to optimize the component of culture medium for the maximum cultivation of Candida sp. and Blastobotrys sp. Molasses and yeast extract were chosen as medium composition and Response Surface Methodology (RSM) was then employed to optimize the molasses and yeast extract. Maximum growth of Candida sp. (7.63 log CFU mL-1) and Blastobotrys sp. (8.30 log CFU mL-1) were obtained from the fermentation. Optimum culture media for the growth of Candida sp., consist of 10% (w/v) molasses and 2% (w/v) yeast extract, while for Blastobotrys sp., were 1.94% (w/v) molasses and 2% (w/v) yeast extract. This study shows that culture medium consists of molasses and yeast extract were able to produce maximum growth of Candida sp. and Blastobotrys sp., as a starter culture for cocoa bean fermentation.
