    Maskaliunas, R; Jankauskas, R; Ramanauskas, J; Locatis, C

    1995-03-01

    This paper discusses the development of an interactive multimedia computer laboratory within the Vilnius University Medical Faculty involving transfer of hardware and courseware developed in the USA. The contexts in which the laboratory was developed are described and factors helping and hindering successful technology transfer are identified. The future of the laboratory and its potential role in international distance education and information access are discussed. While this paper does not focus on international distance education in the traditional sense of offering courses or training from one or more source institutions to individuals off-site, it has implications for providing education internationally, especially in the Baltic and other newly independent states of the former USSR.

  4. Power and uneven globalization: Coalitions and energy trade dependence in the newly independent states of Europe

    2000-10-01

    The economies of the European former Soviet Union were dependent upon energy subsidies in the form of virtually free oil and natural gas imports from Russia, the loss of which implied dramatic shocks to domestic production structures, and the maintenance of which implied continued policy concessions to Russia. Yet some of these states actively pursued integration into the global economy while others sought to maintain the shelter of domestic markets and Russian energy subsidies. While the economic costs of openness and restructuring would be high in all cases in the short term, it is the political costs of openness and restructuring that determine the policy of the state. Where the high costs of restructuring are borne by a politically disenfranchised group, a consensus coalition can emerge in favor of rapid restructuring and energy reorientation. Where the benefits of the status quo accrue to a well-organized coalition closely allied with the state, a consensus coalition emerges in favor of maintenance of energy subsidies from and political relationship with Russia. Where the costs of restructuring are borne broadly or by a well-organized minority group, power oscillation and fragmentation will lead to inconsistent policy and slow progress toward energy reorientation and reform. Integrating a state-in-society approach to coalition formation within the field of international political economy, the author argues that states dominated by globalist-liberalizing-nationalist coalitions were able to implement energy trade reorientation by politically disenfranchising the ethnic minorities who populated the sector most vulnerable to energy contraction, heavy industry. These "globalizers," Estonia and Latvia, bore the high costs of restructuring industries and importing energy at world prices. Belarus, dominated by pro-Moscow-statist-leftist coalitions, sought to preserve energy subsidies through political and economic reintegration with Russia. States ruled by divided

  7. Drumlins of Estonia

    1989-05-01

    Drumlins, megaflutings and other subglacial streamlined forms, highly variable in shape and size, are widely distributed in Estonia as well as on the bottom of the Gulf of Finland, which was also affected by continental ice. Their total number amounts to 1000. The main drumlin fields are most common in Central Estonia on lateral slopes of bedrock uplands and/or in depressions between them, and they serve as a transitional landscape type between predominantly erosional (in northern Estonia) and depositional zones (in southern Estonia) of the Scandinavian ice sheet. Nevertheless, the local details of bedrock topography and glacial and deglacial history have led to some deviations (e.g. the unique Saadjärv field of big drumlins and megaflutings is situated in a "glacier shadow", on the lee side of a bedrock upland). Being of varied composition and age, drumlins and related streamlined forms represent complex interactions between erosional, transporting and depositional processes, although the dynamics of their formation are still somewhat enigmatic. It seems that in Estonia drumlins were formed both during ice advances and retreats. In some cases there are moraine hillocks, kames and eskers and other ice disintegration features superimposed on drumlins.

  8. Power politics: National energy strategies of the nuclear newly independent states of Armenia, Lithuania and Ukraine

    NASA Astrophysics Data System (ADS)

    Sabonis-Chafee, Theresa Marie

    The successor states of Armenia, Lithuania and Ukraine arrived at independence facing extraordinary challenges in their energy sectors. Each state was a net importer, heavily dependent on cheap energy supplies, mostly from Russia. Each state also inherited a nuclear power complex over which it had not previously exercised full control. In the time period 1991--1996, each state attempted to impose coherence on the energy sector, selecting a new course for the pieces it had inherited from a much larger, highly integrated energy structure. Each state attempted to craft national energy policies in the midst of severe supply shocks and price shocks. Each state developed institutions to govern its nuclear power sector. The states' challenges were made even greater by the fact that they had few political or economic structures necessary for energy management, and sought to create those structures at the same time. This dissertation is a systematic, non-quantitative examination of how each state's energy policies developed during the 1991--1996 time period. The theoretical premise of the analysis (drawn from Statist realism) is that systemic variables---regional climate and energy vulnerability---provide the best explanations for the resulting energy policy decisions. The dependent variable is defined as creation and reform of energy institutions. The independent variables include domestic climate, regional climate, energy vulnerability and transnational assistance. All three states adopted rhetoric and legislation declaring energy a strategic sector. The evidence suggests that two of the states, Armenia and Lithuania, which faced tense regional climates and high levels of energy vulnerability, succeeded in actually treating energy strategically, approaching energy as a matter of national security or "high politics." The third state, Ukraine, failed to do so. The evidence presented suggests that the systemic variables (regional climate and energy vulnerability) provided a

    The present report provides data on the mitigation analysis of Estonia. The results for energy, forest and agricultural sectors and macro-economic analysis are given. The Government of Estonia has identified the development of energy production as the main strategical means in the movement towards market economy. Now 99% of electricity generation and about 25% of heat production in Estonia is based on oil shale combustion. To increase the efficiency of oil shale-fired power plants and decrease CO{sub 2} emissions, the State Enterprise (SE) Eesti Energia (Estonian Energy) is planning to reconstruct these power plants and introduce the Circulating Fluidized Bed (CFB) combustion technology for oil shale burning to replace the Pulverized Combustion (PC). According to the Estonian Forest Policy, two general objectives are of importance: sustainability in forestry and efficiency in forest management. For the reduction of greenhouse gases (GHG) emissions from agriculture, it is necessary to increase the efficiency of production resource usage. The growth of the GDP in 1995 was 2.9% as a result of large-scale privatization activities in Estonia and re-introduction of the available, but unused production capacities with the help of foreign and domestic investments. It is assumed that the medium growth rate of GDP reaches 6% in 1998.

    The compulsory vaccination of pets, the recommended vaccination of farm animals in grazing areas and the extermination of stray animals did not succeed in eliminating rabies in Estonia because the virus was maintained in two main wildlife reservoirs, foxes and raccoon dogs. These two species became a priority target therefore in order to control rabies. Supported by the European Community, successive oral vaccination (OV) campaigns were conducted twice a year using Rabigen® SAG2 baits, beginning in autumn 2005 in North Estonia. They were then extended to the whole territory from spring 2006. Following the vaccination campaigns, the incidence of rabies cases dramatically decreased, with 266 cases in 2005, 114 in 2006, four in 2007 and three in 2008. Since March 2008, no rabies cases have been detected in Estonia other than three cases reported in summer 2009 and one case in January 2011, all in areas close to the South-Eastern border with Russia. The bait uptake was satisfactory, with tetracycline positivity rates ranging from 85% to 93% in foxes and from 82% to 88% in raccoon dogs. Immunisation rates evaluated by ELISA ranged from 34% to 55% in foxes and from 38% to 55% in raccoon dogs. The rabies situation in Estonia was compared to that of the other two Baltic States, Latvia and Lithuania. Despite regular OV campaigns conducted throughout their territory since 2006, and an improvement in the epidemiological situation, rabies has still not been eradicated in these countries. An analysis of the number of baits distributed and the funding allocated by the European Commission showed that the strategy for rabies control is more cost-effective in Estonia than in Latvia and Lithuania.

    Countries from South-East Europe (SEE), Central and Eastern Europe (CEE) and Newly Independent States (NIS) are in the process of harmonization with European environmental noise legislation. However, research work on noise and health was performed in some countries independently of harmonization process of adoption and implementation of legislation for environmental noise. Aim of this review is to summarize available evidence for noise induced sleep disturbance in population of CEE, SEE and NIS countries and to give directions for further research work in this field. After a systematic search through accessible electronic databases, conference proceedings, PhD thesis, national reports and scientific journals in English and non-English language, we decided to include six papers and one PhD thesis in this review: One paper from former Yugoslavia, one paper from Slovakia, one paper from Lithuania, two papers from Serbia and one paper, as also one PhD thesis from The Former Yugoslav Republic of Macedonia. Noise exposure assessment focused on road traffic noise was mainly performed with objective noise measurements, but also with noise mapping in case of Lithuanian study. Sleep disturbance was assessed with the questionnaire based surveys and was assumed from dose-effect relationship between night-time noise indicator (Lnight ) for road traffic noise and sleep disturbance (for Lithuanian study). Although research evidence on noise and sleep disturbance show to be sufficient for establishing dose response curves for sleep disturbance in countries where studies were performed, further research is needed with particular attention to vulnerable groups, other noise sources, development of laboratory research work and common methodology in assessment of burden of diseases from environmental noise.

    Immune suppression is a hallmark of multiple myeloma (MM), but data on soluble factors involved in the fate of immune effector cells are limited. The CXCR3-binding chemokine monokine induced by interferon-gamma (MIG/CXCL9) has been associated with tumor progression, immune escape, and angiogenesis in several malignancies. We here aimed to evaluate the prognostic relevance of MIG in MM. MIG serum levels were significantly elevated in newly diagnosed MM patients (n = 105) compared to patients with monoclonal gammopathy of undetermined significance (MGUS; n = 17) and healthy controls (n = 37). MIG expression in stromal compartments but not purified MM cells correlated with serum levels. High MIG serum levels were significantly associated with established prognostic markers (international staging system: R = 0.25, p = 0.001; age: R = 0.47, p < 0.0001; lactate-dehydrogenase: R = 0.34, p = 0.0005) and poor overall survival (OS) (median OS 17.0 months vs. not reached, p < 0.001). A similar association was found for CXCL10 and CXCL11. Multivariate regression analysis indicated MIG as an independent prognostic factor of OS. PMID:26999330

    The situation of women in education, work, and research in Estonia is relatively good. Nevertheless, science (especially engineering) remains a male-dominated field. The total number of female scientists and engineers in the workforce is about two-thirds that of males. Moreover, the gender imbalance in the researcher population increases with age. Significant pay-gap and power imbalances between the genders remain both in Estonian society in general and in the fields of science and technology. In many practical situations, behavior of both men and women is still guided by gender stereotypes.

    Background. The effects of smoking on human metabolism are complex. Although smoking increases risk for diabetes mellitus, smoking cessation was also reported to be associated with weight gain and incident diabetes mellitus. We therefore conducted this study to clarify the association between smoking status and newly diagnosed diabetes mellitus. Methods. An analysis was done using the data of a mass health examination performed annually in an industrial park from 2007 to 2013. The association between smoking status and newly diagnosed diabetes mellitus was analyzed with adjustment for weight gain and other potential confounders. Results. Compared with never-smokers, not only current smokers but also ex-smokers in their first two years of abstinence had higher odds ratios (ORs) for newly diagnosed diabetes mellitus (never-smokers 3.6%, OR as 1; current smokers 5.5%, OR = 1.499, 95% CI = 1.147–1.960, and p = 0.003; ex-smokers in their first year of abstinence 7.5%, OR = 1.829, 95% CI = 0.906–3.694, and p = 0.092; and ex-smokers in their second year of abstinence 9.0%, OR = 2.020, 95% CI = 1.031–3.955, and p = 0.040). Conclusion. Smoking cessation generally decreased risk for newly diagnosed diabetes mellitus. However, increased odds were seen within the first 2 years of abstinence independently of weight gain.

    This analysis of the Estonian health system reviews recent developments in organization and governance, health financing, health-care provision, health reforms and health system performance. Without doubt, the main issue has been the 2008 financial crisis. Although Estonia has managed the downturn quite successfully and overall satisfaction with the system remains high, it is hard to predict the longer-term effects of the austerity package. The latter included some cuts in benefits and prices, increased cost sharing for certain services, extended waiting times, and a reduction in specialized care. In terms of health outcomes, important progress was made in life expectancy, which is nearing the European Union (EU) average, and infant mortality. Improvements are necessary in smoking and alcohol consumption, which are linked to the majority of avoidable diseases. Although the health behaviour of the population is improving, large disparities between groups exist and obesity rates, particularly among young people, are increasing. In health care, the burden of out-of-pocket payments is still distributed towards vulnerable groups. Furthermore, the number of hospitals, hospital beds and average length of stay has decreased to the EU average level, yet bed occupancy rates are still below EU averages and efficiency advances could be made. Going forwards, a number of pre-crisis challenges remain. These include ensuring sustainability of health care financing, guaranteeing a sufficient level of human resources, prioritizing patient-centred health care, integrating health and social care services, implementing intersectoral action to promote healthy behaviour, safeguarding access to health care for lower socioeconomic groups, and, lastly, improving evaluation and monitoring tools across the health system.

    Abstract There is growing evidence that chemerin, a novel adipokine elevated in obesity and metabolic syndromes, plays a crucial role in advanced atherosclerosis. This study aimed to determine the chemerin levels in diabetes and evaluate the effects of increased chemerin on early atherosclerosis. A total of 245 newly diagnosed diabetic patients and 148 age-matched, healthy, normal glucose tolerant (NGT) controls were enrolled. Anthropometric measurements and plasma parameters were examined, including body mass index (BMI), waist circumference, blood pressure, glucose, lipid profiles, inflammation markers, adipokines, and cell adhesion molecules. Vascular healthy was measured with brachial flow-mediated dilatation (FMD) and carotid intima-media thickness (IMT). Compared with NGT controls, plasma chemerin levels were higher in diabetic patients (P < 0.01) and higher chemerin level was an independent risk factor of occurrence of diabetes even after metabolic profiles were adjusted (odds ratio [OR] = 1.352, 95% CI: 1.181–1.543, P < 0.01). In patients with type 2 diabetes, chemerin was positively associated with intercellular adhesion molecule-1 (ICAM-1), E-selectin, but not vascular adhesion molecule-1 (VCAM-1) and P-selectin. We also explored that plasma chemerin level was negatively associated with brachial FMD and positively with carotid IMT. Chemerin also retained a strong association with ICAM-1, FMD, and IMT even after adjusted for age, sex, and other risk factors (ICAM-1: r = 0.150, P = 0.024; FMD: r = −0.126, P = 0.001; IMT: r = 0.325, P < 0.001). By multiple linear regression analysis, plasma chemerin levels were related to ICAM-1 even after adjustments for conventional cardiovascular risk factors (β = 0.192, P = 0.017). Moreover, logistic regression analysis showed that high chemerin level was an independent predictive variable for impaired endothelial function (OR = 1.066, 95% CI: 1.012–1.142, P = 0

    The aim of this study was to examine past mammography use and mode of detection among breast cancer (BC) patients in Estonia, a country that has low screening coverage and high BC mortality. Women newly diagnosed with primary BC in Estonia in 2008-2010 were interviewed. Determinants of past mammography use and the detection of BC by mammography were studied using multivariate logistic regression. Among 977 participants, almost half reported no mammograms prior to the detection of BC. Overall, 22% of the cases were detected by mammography (16% by screening mammography). Detection by mammography was strongly related to age, past mammography use, and obesity. Among cases detected by mammography, 10% were stage III/IV at diagnosis (32% among cases detected by other modes). This study showed low mammography utilization and high rate of self-detection of BC in Estonia. Increased detection by mammography would help diagnose the disease at an earlier stage and consequently avoid premature BC deaths. Efforts should be undertaken to increase participation in screening and improve the availability of mammography among older and high-risk women. The results are likely to be relevant for other countries and population groups with low screening coverage. PMID:26327255

    Background On-going climate change is predicted to result in a growing number of extreme weather events—such as heat waves—throughout Europe. The effect of high temperatures and heat waves are already having an important impact on public health in terms of increased mortality, but studies from an Estonian setting are almost entirely missing. We investigated mortality in relation to high summer temperatures and the time course of mortality in a coastal and inland region of Estonia. Methods We collected daily mortality data and daily maximum temperature for a coastal and an inland region of Estonia. We applied a distributed lag non-linear model to investigate heat related mortality and the time course of mortality in Estonia. Results We found an immediate increase in mortality associated with temperatures exceeding the 75th percentile of summer maximum temperatures, corresponding to approximately 23°C. This increase lasted for a couple of days in both regions. The total effect of elevated temperatures was not lessened by significant mortality displacement. Discussion We observed significantly increased mortality in Estonia, both on a country level as well as for a coastal region and an inland region with a more continental climate. Heat related mortality was higher in the inland region as compared to the coastal region, however, no statistically significant differences were observed. The lower risks in coastal areas could be due to lower maximum temperatures and cooling effects of the sea, but also better socioeconomic condition. Our results suggest that region specific estimates of the impacts of temperature extremes on mortality are needed. PMID:27167851

    We investigated the incidence and 30-day case-fatality of childhood stroke in Estonia, and clinical signs and risk factors of childhood stroke. A retrospective (1995-2003) and prospective study (2004-2006) of childhood stroke (arterial ischemic, hemorrhagic, and sinovenous thrombosis) and transient ischemic attack was conducted. Stroke-incidence calculation was based on the prospective study. Clinical diagnoses of stroke were confirmed by neuroradiology. The incidence rate of childhood stroke in Estonia was 2.73/100,000 person-years for children aged 30 days to 18 years: 1.61/100,000 for arterial ischemic stroke, 0.87/100,000 for hemorrhagic stroke, 0.25/100,000 for sinovenous thrombosis, and 0.37/100,000 for transient ischemic attack. No arterial ischemic stroke patients died within 30 days, but case-fatality for intracerebral hemorrhage was 46%. Focal signs occurred in 100% of arterial ischemic strokes and 64% of intracerebral hemorrhage cases. Risk factors were identified in 35/48 (73%) children with cerebrovascular attacks. Six children with arterial ischemic stroke (6/24, 25%) manifested more than one risk factor. The incidence rate of childhood stroke in Estonia is similar to that in earlier data.

  8. Mannitol promotes adherence of an outbreak strain of Burkholderia multivorans via an exopolysaccharide-independent mechanism that is associated with upregulation of newly identified fimbrial and afimbrial adhesins.

    Burkholderia multivorans, a member of the Burkholderia cepacia complex (Bcc), is an important pathogen of the cystic fibrosis (CF) lung. Mannitol, approved as an inhaled osmolyte therapy for use in CF patients, promotes exopolysaccharide (EPS) production by the Bcc. In the present study, we investigated the role of mannitol-induced EPS in the adherence of B. multivorans. We report that mannitol promoted adherence of two representative B. multivorans strains. However, whilst this enhanced adherence was largely EPS-dependent in an environmental isolate, it was EPS-independent within a CF outbreak strain, suggesting strain-to-strain variation in adhesins. Genome sequencing of the outbreak strain enabled the identification of two distinct loci encoding putative fimbrial and afimbrial adhesins. The putative fimbriae-encoding locus was found to be widely distributed amongst clinical and environmental B. multivorans. In contrast, the locus encoding the putative afimbrial adhesin (of the filamentous haemagglutinin family, FHA) was restricted to clinical isolates. Both loci contributed to biofilm formation and mucin adherence. Furthermore, we report that mannitol promoted expression of both loci, and that the locus encoding the putative FHA-family adhesin is a key determinant of the enhanced adherence observed following growth in mannitol. Our studies provide the first characterization, to our knowledge, of B. multivorans adhesins, and in so doing highlight the strain-dependent role of EPS in the Bcc and the difficulties in assigning phenotypic traits to Bcc EPS due to the wider response to mannitol. Our observations also highlight the need to monitor the microbiological effects of inhaled mannitol therapy in Bcc-infected CF patients.

    Renal failure (RF) is a common and severe complication of symptomatic myeloma, associated with significant morbidity and mortality. Such patients are commonly excluded from clinical trials. Bortezomib/dexamethasone (VD)-based regimens are the backbone of the treatment of newly diagnosed MM patients who present with severe RF even those requiring dialysis. We analyzed the outcomes of 83 consecutive bortezomib-treated patients with severe RF (eGFR < 30 ml/min/1.73 m(2) ), of which 31 (37%) required dialysis. By IMWG renal response criteria, 54 (65%) patients achieved at least MRrenal, including CRrenal in 35% and PRrenal in 12%. Triplet combinations (i.e., VD plus a third agent) versus VD alone were associated with higher rates of renal responses (72 vs. 50%; P = 0.06). Fifteen of the 31 (48%) patients became dialysis independent within a median of 217 days (range 11-724). Triplets were associated with a higher probability of dialysis discontinuation (57 vs. 35%). Serum free light chain (sFLC) level ≥11,550 mg/L was associated with lower rates of major renal response, longer time to major renal response, lower probability, and longer time to dialysis discontinuation. Rapid myeloma response (≥PR within the first month) was also associated with higher rates of renal response. Patients who became dialysis-independent had longer survival than those remaining on dialysis. In conclusion, VD-based triplets are associated with a significant probability of renal response and dialysis discontinuation, improving the survival of patients who became dialysis independent. Rapid disease response is important for renal recovery and sFLCs are predictive of the probability and of the time required for renal response.

    Wind chill equivalent temperature (WCET) is used to define thermal discomfort in winter months. Directional distributions of winds, which are associated with uncomfortable weather, were composed of three climatologically different Estonian locations: Vilsandi, Kuusiku, and Jõhvi. Cases with wind chill equivalent temperature <-10 °C, which could be classified as "uncomfortable or worse," were investigated. Additional thresholds were used to measure weather risk. The 25th percentile of daily minimum WCET was tested to measure classical prevalent wind directions in Estonia: W, SW, and NW bring warm air in winter from the North Atlantic, while winds from the East-European plain (NE, E, and SE) are associated with cold air. The eastern prevalence was stronger when a lower threshold was used. A directional approach may find several applications, such as building, agricultural, landscape, or settlement planning.

    During the last decade, there has been a dramatic increase in intravenous drug use in young adults in Estonia with an increased incidence of both hepatitis B and C as a consequence. Since genetic data are limited regarding hepatitis C virus (HCV) strains in Estonia, the aim of the study was to characterize HCV strains in different risk groups to determine their relatedness to strains from other geographical regions. Three hundred fifty-three anti-HCV positive sera collected during 1994-2004 from hospitalized patients, blood donors and health care workers were used as source of HCV RNA. Two hundred nine (59%) of the sera were positive for HCV RNA by PCR directed to the 5'-UTR region. For 174 strains the HCV subtype was determined by analyses of the NS5B and/or the 5'UTR-core regions. 1b (71%) was the most common subtype followed by 3a (24%), 2c (2%), 1a (1%), and 2a (1%). The 1b and 3a strains were similar to strains from other regions of the former USSR. Within genotype 1b there were several HCV lineages. However, for 3a there seemed to be two separate introductions into Estonia. There was a relative shift from subtype 1b to 3a in 1999-2000 with a further replacement of 3a with 1b in intravenous drug users in 2001 and onwards (P < 0.05). However, both subtypes were found to co-circulate in the community independent of risk factors. One patient was infected with the 2k/1b recombinant presumed to originate from St. Petersburg being the first isolate of this recombinant recovered outside Russia. PMID:17311333

    2011-08-01

    Ethnic minority-majority unions-also referred to as mixed ethnic unions-are often seen as the ultimate evidence of the integration of ethnic minorities into their host societies. We investigated minority-majority unions in Estonia, where ethnic minorities account for one-third of the total population (Russians 26%, followed by Ukrainians, Byelorussians, Finns and other smaller groups). Using data from the 2000 Estonian census and regression models, we found that Slavic women are less likely to be in minority-majority unions than are members of other minority groups, with Russians being the least likely. Finns, who are culturally most similar to the Estonian majority population, are the most likely to form a union with an Estonian. For ethnic minority women, the likelihood of being in minority-majority unions is highest in rural areas and increases over generations, with third-generation immigrants being the most likely. Estonian women are most likely to have a minority partner when they or their parents were born abroad and when they live in urban areas. Our findings suggest that both the opportunity to meet potential partners and openness to other ethnic groups are important factors for understanding the dynamics of minority-majority unions.

    Five mammoth molars, four pieces of tusk and one bone fragment found in different parts of Estonia were radiocarbon dated using the AMS method. Six of the analysed samples gave an infinite date. These remains originate most likely from an ice-free period during the Early Weichselian or early Middle Weichselian. The molar from Mooste, southeast Estonia was dated at 31,000 BP, and seems thus to belong to the same faunal complex as several other previously dated mammoth specimens recovered in Finland and other Nordic countries. Two molars from Puurmani, central Estonia gave an age of ca 10,000 BP, suggesting a late relict mammoth population living in northeast Europe during the Late Pleistocene/Early Holocene transition.

    This paper presents the results of a reinvestigation of the object which allegedly fell at Igast, Estonia, in 1855, and which may be the only example of a meteorite with the chemical composition of a tektite. R is concluded that generally quoted opinions of the artificial nature of this object are based on spurious samples, specifically melted brick and quartz basalt porphyry distributed by a Russian collector. Possibly genuine specimens from this observed fall are in the British Museum, the Paris Museum, and perhaps at the University of Dorpat, Estonia. It is recommended that these specimens be re-examined and that a search for similar objects be made.

    BACKGROUND AND OBJECTIVE. A constant gap has appeared in infant mortality among the 3 Baltic States - Latvia, Estonia, and Lithuania - since the restoration of independence in 1991. The aim of the study was to compare infant mortality rates in all the 3 Baltic countries and examine some of the macro- and socioeconomic factors associated with infant mortality. MATERIAL AND METHODS. The data were obtained from international databases, such as World Health Organization and EUROSTAT, and the national statistical databases of the Baltic States. The time series data sets (1996-2010) were used in the regression and correlation analysis. RESULTS. In all the 3 Baltic States, a strong and significant correlation was found: Latvia (r=-0.81, P<0.01), Lithuania (r=-0.93, P<0.01), and Estonia (r=-0.91, P<0.01). There was also a correlation between infant mortality and healthcare expenditure in local currency per capita: Latvia (r=-0.81, P<0.01); Lithuania (r=-0.90, P<0.01) and Estonia (r=-0.88, P<0.01). In Latvia (r=0.87, P<0.01) and Estonia (r=0.70; P<0.01), a significant correlation between infant mortality and unemployment levels was observed from 1996 to 2008, whereas the statistical significance disappeared in the period from 1996 to 2010. In Lithuania, the relationship was not significant. CONCLUSIONS. Higher infant mortality rates and a less stable decreasing tendency in Latvia are apparently explained by less successful adaptation to a new political and economic situation and limited skills in adjusting the healthcare system to the reality of life.

    OBJECTIVES: To study and report the attitudes and practices of physicians in a former Soviet republic regarding issues pertaining to patients' rights, physician negligence and the acceptance of gratuities from patients. DESIGN: Survey questionnaire administered to physicians in 1991 at the time of the Soviet breakup. SETTING: Estonia, formerly a Soviet republic, now an independent state. SURVEY SAMPLE: A stratified, random sample of 1,000 physicians, representing approximately 20 per cent of practicing physicians under the age of 65. RESULTS: Most physicians shared information with patients about treatment risks and alternatives, with the exception of cancer patients: only a third of physicians tell the patient when cancer is suspected. Current practice at the time of the survey left patients few options when physician negligence occurred; most physicians feel that under a reformed system physician negligence should be handled within the local facility rather than by the government. It was common practice for physicians to receive gifts, tips, or preferential access to scarce consumer goods from their patients. Responses varied somewhat by facility and physician nationality. CONCLUSION: The ethics of Soviet medical practice were different in a number of ways from generally accepted norms in Western countries. Physicians' attitudes about the need for ethical reform suggest that there will be movement in Estonia towards a system of medical ethics that more closely approximates those in the West.

    2006-05-01

    Pleistocene chronostratigraphy in Estonia is based on 29 studied sites/sections, the dating of which covers a span from approximately 200 ka BP to the Pleistocene—Holocene chronostratigraphic boundary, and a local varved clay chronology for eastern Estonia, which enables tentative correlation of Lateglacial (LG) events to Finnish and Swedish varve chronologies. Analysis of existing and unpublished data was used to review the current Pleistocene chronostratigraphy and particularly the history of Weichselian Cold Stage in Estonia. OSL ages from fluvial deposits that included the Kõrveküla (Holsteinian) or Rõngu (Eemian) continental interglacial deposits revealed that the pre-Weichselian interglacial deposits were glacially dislocated during the Weichselian. Available OSL/TL and 14C dates and new 14C AMS ages of mammoth bones indicate ice-free conditions between 105 and 68 ka BP and a comparatively mild Middle Weichselian between 43 and 22 ka BP. The LG chronology indicates in general rapid (average 110 m/yr) deglaciation of the territory between ca 14.7 and 12.7 ka BP. The duration of the Late Weichselian glaciation in Estonia ranged between 7.3 and 9.3 ka.

    Knowledge about suicide might be positively correlated with local suicide prevalence. This hypothesis was tested with a sample of 107 medical and social science undergraduates from Estonia, a country with a high suicide rate, using Hubbard and McIntosh's 1992 Revised Facts on Suicide Quiz. Compared (independent-groups t tests) with a sample of undergraduates from Austria, which has a markedly lower suicide rate, Estonians presented significantly higher overall knowledge about suicide (d = 0.39), particularly concerning demographic and epidemiological facts about suicide (d = 0.77) but not pertaining to clinical and interpersonal knowledge contents (d = -0.06). Study limitations and suggestions for extension of this preliminary inquiry are discussed. PMID:17918542

    Epilobium species have been traditionally used as medicinal plants to treat benign prostate hyperplasia. The present study investigated the content of polyphenols, tannins, and flavonoids in Epilobium parviflorum Schreb., E. hirsutum L., E. adenocaulon Hausskn., E. montanum L., and E. palustre L. growing in Estonia. The total contents of polyphenols, tannins, and flavonoids were studied using UV spectroscopy with subsequent HPLC quantification of gallic acid, ellagic acid, and quercetin as marker compounds. All roots, stems, leaves, and flowers of the plants investigated contained comparable amounts of polyphenols, tannins, and flavonoids. There was a clear positive correlation between the contents of tannins and flavonoids in various plant parts. The content of these biologically active compounds suggests the use of E. parviflorum, E. hirsutum, E. adenocaulon, E. montanum, and E. palustre collected from Estonia as herbs both individually or as a blend.

  6. Atmospheric aerosol variability in Estonia calculated from solar radiation measurements

    1996-10-01

    Direct solar radiation data obtained during 1955 1994 at the Tõravere Actinometric Station (Estonia) have been used to study the long-term variations of the atmospheric aerosol. In a linear approximation, the optical thickness of atmospheric aerosol averaged over months from April to August has increased by 73% at Tõravere during the last 40years. The aerosol loading of the atmosphere depends on wind direction, the southern and southeastern winds being the main carriers of aerosol. During the last decade, the increase in the optical thickness of aerosol in the case of W-, NW- and N-winds has slowed down. This is most likely caused by a reduction in the SO2 emission in Western and Central Europe as well as in Finland. In April, the advection of aerosol is greatest from the NE-direction. We suppose that this effect points to the possibility of aerosol transfer to Estonia through the Arctic regions.

  9. Seasonality of alcohol-related phenomena in Estonia

    2005-03-01

    We studied alcohol consumption and its consequences as a seasonal phenomenon in Estonia and analysed the social and environmental factors that may cause its seasonal rhythm. There are two important questions when researching the seasonality of human activities: (1) whether it is caused by natural or social factors, and (2) whether the impact of the factors is direct or indirect. Often the seasonality of social phenomena is caused by social factors, but the triggering mechanisms are related to environmental factors like temperature, precipitation, and radiation via the circannual calendar. The indicators of alcohol consumption in the current paper are grouped as: (1) pre-consumption phenomena, i.e. production, tax and excise, sales (beer, wine and vodka are analysed separately), and (2) post-consumption phenomena, i.e. alcohol-related crime and traffic accidents and the number of people detained in lockups and admitted to alcohol treatment clinics. In addition, seasonal variability in the amount of alcohol advertising has been studied, and a survey has been carried out among 87 students of Tartu University. The analysis shows that different phenomena related to alcohol have a clear seasonal rhythm in Estonia. The peak period of phenomena related to beer is in the summer, from June to August and the low point is during the first months of the year. Beer consumption correlates well with air temperature. The consumption of vodka increases sharply at the end of the year and in June; the production of vodka does not have a significant correlation with negative temperatures. The consumption of wine increases during summer and in December. The consequences of alcohol consumption, expressed as the rate of traffic accidents or the frequency of medical treatment, also show seasonal variability. Seasonal variability of alcohol consumption in Estonia is influenced by natural factors (temperature, humidity, etc.) and by social factors (celebrations, vacations, etc.). However

    Thyroid examinations, including palpation, ultrasound and, selectively, fine-needle aspiration biopsy, were conducted on nearly 2,000 Chernobyl cleanup workers from Estonia to evaluate the occurrence of thyroid cancer and nodular thyroid disease among men with protracted exposure to ionizing radiation. The examinations were conducted in four cities in Estonia during March-April 1995, 9 years after the reactor accident. The study population was selected from a predefined cohort of 4,833 cleanup workers from Estonia under surveillance for cancer incidence. These men had been sent to Chernobyl between 1986 and 1991 to entomb the damaged reactor, remove radioactive debris and perform related cleanup activities. A total of 2,997 men were invited for thyroid screening and 1,984 (66%) were examined. Estimates of radiation dose from external sources were obtained from military or other institutional records, and details about service dates and types of work performed while at Chernobyl were obtained from a self-administered questionnaire. Blood samples were collected for assay of chromosomal translocations in circulating lymphocytes and loss of expression of the glycophorin A (GPA) gene in erythrocytes. The primary outcome measure was the presence or absence of thyroid nodules as determined by the ultrasound examination. Of the screened workers, 1,247 (63%) were sent to Chernobyl in 1986, including 603 (30%) sent in April or May, soon after the accident. Workers served at Chernobyl for an average of 3 months. The average age was 32 years at the time of arrival at Chernobyl and 40 years at the time of thyroid examination. The mean documented radiation dose from external sources was 10.8 cGy. Biological indicators of exposure showed low correlations with documented dose, but did not indicate that the mean dose for the population was higher than the average documented dose. 47 refs., 1 fig., 9 tabs.

    Kukersite samples from Estonia and Iowa were analyzed for elemental composition, functional group distribution, and carbon and hydrogen stable isotope ratios. The elemental and hydrogen isotope values, together with other analytical data, suggest a higher thermal maturity for the Iowa kukersite. The wide carbon isotopic range of 9.3??? among kukersites, with unusually negative ??13C values reaching -33.2???, indicates isotopically variable carbon sources for production of biomass, and thus major paleoceanographic differences between the environments supporting biosynthesis. ?? 2003 Elsevier Ltd.

    The only available gravity dataset covering the whole of Estonia has been observed from 1949 to 1958. This historic dataset has been used as a main input source for many applications including the geoid determination, the realization of the height system, the geological mapping. However, some recent studies have been indicated remarkable systematic biases in the dataset. For instance, a comparison of modern gravity control points with the historic data revealed unreasonable discrepancies in a large region in South-Estonia. However, the distribution of the gravity control was scarce, which did not allow to fully assess the quality of the historic data in the study area. In 2008 a pilot project was called out as a cooperation between Estonian Land Board, Geological Survey of Estonia, Tallinn University of Technology and Estonian University of Life Sciences to densify the detected problematic area (about 2000 km2) with new and reliable gravity data. Field work was carried out in October and November 2008, whereas GPS RTK and relative Scintrex gravimeter CG5 were used for precise positioning and gravity determinations, respectively. Altogether more than 140 new points were determined along the roads. Despite bad weather conditions and unstable observation base of the gravimeter (mostly on the bank of the road), uncertainty better than ±0.1 mGal (1 mGal = 10-5 m/s2) was estimated from the adjustment of gravimeter's readings. The separate gravity dataset of the Estonian Geological Survey were also incorporated into the gravity database of the project for further analysis. Those data were collected within several geological mapping projects in 1981-2007 and contain the data with uncertainty better than ±0.25 mGal. After the collection of new gravity data, a Kriging with proper variogram modeling was applied to form the Bouguer anomaly grids of the historic and the new datasets. The comparison of the resulting grids revealed biases up to -4 mGal at certain regions

    Background The aim of this study was to examine breast cancer (BC) incidence and mortality trends in Estonia during recent decades and to compare the pattern of these trends with other selected European countries and regions. We attempt to explain the findings in relation to changes in Estonian society and healthcare system. Methods BC incidence (1985-2012) and mortality (1985-2013) data for Estonia were obtained from the Estonian Cancer Registry and Statistics Estonia. Data for selected European countries were obtained from the EUREG database. Joinpoint regression was used to analyze age-standardized rates in Estonia by age. For international comparison of incidence and mortality rates, we used scatterplot with 95% confidence ellipses and the mortality to incidence ratio. Results The overall BC incidence continues to increase in Estonia, while mortality has been in decline since 2000. Both incidence and mortality trends varied considerably across age groups. Among women aged 60 years and older, BC incidence increased at a rate of nearly 3% per year. Significant decrease in mortality was seen only among women aged 50-59 years. Comparison of scatterplots between countries and regions revealed two clusters in Europe separated along the incidence axis. The correlation between incidence and mortality in Estonia changed its direction in the mid-1990s. Conclusion In recent years, the dynamics of BC burden in Estonia has transitioned towards the high incidence-low mortality type model, which is characteristic to Western, Northern and Southern Europe. Although overall BC incidence is much lower in Estonia than in more affluent European countries, mortality from BC is still relatively high, particularly among elderly women. PMID:27222251

    The largest recent landslide in Estonia (ca 60 000 m 3), which occurred on 19 December 2005, has been investigated, modelled and monitored. Eight boreholes, geotechnical sampling and nine vane shear tests provided data on the geological setting, soil strength parameters and location of the rupture zones. Topographic surveys were carried out twice a year from April 2006 to April 2009 to monitor the evolution of the slope. Limit equilibrium modelling displayed a complex of six separate retrogressive failures, beginning near to the Sauga River and ending 75 m from the former river channel. Modelling results are in agreement with the actual morphology of the multiple landslides. Monitoring records the enlargement of the landslide as the Sauga River downcuts through the slide and erodes its toe. Strength loss in the varved clays underlying the slope is a key factor in failure development.

    2013-02-01

    A method of moving precipitation totals is described and applied for the analysis of precipitation extremes in Estonia. Numbers of extremely wet and extremely dry days and other indices of precipitation extremes were calculated using the daily precipitation data measured at 51 stations over Estonia during 1957-2009. Mean regularities of spatial and seasonal distribution were determined. Long-term changes were detected using Sen's method and Mann-Kendall test. The highest risk of heavy precipitation is in the regions of higher mean precipitation on the uplands and on the belt of higher precipitation in the western part of continental Estonia. Wet spells have their sharp maxima in July and August. The highest risk of droughts is observed in the coastal regions of West Estonia. In the coastal area, droughts appear mostly in the first half of summer, while in the eastern Estonia, they are usually observed during the second half of summer. Extreme precipitation events have become more frequent and intense. Statistically significant increasing trends were, first of all, found in the time series of winter extreme precipitation indices. In summer and autumn, trends existed in some indices, but in spring, there were no trends at all. There were no trends in time series of dryness indices in Estonia in 1957-2009.

    This 8-image mosaic was acquired during the late afternoon (near 5pm LST, note the long shadows) on Sol 2 as part of the predeploy 'insurance panorama' and shows the newly deployed rover sitting on the Martian surface. This color image was generated from images acquired at 530,600, and 750 nm. The insurance panorama was designed as 'insurance' against camera failure upon deployment. Had the camera failed, the losslessly-compressed, multispectral insurance panorama would have been the main source of image data from the IMP.

    However, the camera deployment was successful, leaving the insurance panorama to be downlinked to Earth several weeks later. Ironically enough, the insurance panorama contains some of the best quality image data because of the lossless data compression and relatively dust-free state of the camera and associated lander/rover hardware on Sol 2.

    2012-04-01

    The openness of the coast to the winds and storm waves has an important part in changing aeolian coastal landscapes as well as anthropogenic factor. The aeolian coastal landscapes are probably the most dynamic areas. Occurrence of aeolian coastal landscapes in Estonia is limited. They consist of sandy beaches, sandy beach ridges and dunes. The coastal ecosystems are strongly affected by their topography, based on the character of deposits and moisture conditions. The majority of their ecosystems are quite close to the specific natural habitat. These ecosystems are represented in the list of the European Union Habitats (Natura 2000). In recent decades human influence has changed the landscape over time in different activities (recreation, trampling, off-road driving) and their intensities, which has led to destruction or degradation of various habitats. Previously coastal landscapes were used for forestry and pasture. Nowadays one of the most serious threats to open landscape is afforestation. This study examines the relationships between landscape components during last decades. Trying to find out how much aeolian coastal landscapes are influenced by natural processes or human activities. The results are based on cartographic analysis, fieldwork data. The method of landscape complex profile was used. The profiles show a cross-sections of landforms and interrelationships between landscape components, most frequently describing the relations between soils and vegetation. In each sample point the mechanical composition of sediments, vegetation cover and soil is determined. Results show that changes in landscapes are induced by their own development as well as changes in environmental factors and human activities. Larger changes are due to increase of coastal processes activity. These processes can be observed in sandy beaches, which are easily transformed by waves. Higher sea levels during storm surges are reaching older beach formation, causing erosion and creating

  2. Women in Physics in Estonia: Many Duties, One Life

    NASA Astrophysics Data System (ADS)

    Kaasik, Helle

    2009-04-01

    In Estonia, women and men have equal legal rights. Women are expected to earn their living like men—and unlike men, to be the main (often the only) caregiver for the children. In the family women do most of the unpaid work, spending twice the amount of time on household duties as men. Laws about public preschool child care and child support obligations for noncustodial parents exist, but these laws are not always realized in practice. A generous policy of benefits for children under 1.5 years provides some relief for mothers. It is a challenge to balance a woman's traditional load of unpaid duties with the high demands of a science career. As in many other countries, with every step up the academic ladder the underrepresentation of women in science becomes more evident. Physics and engineering are perceived as male areas and women active in these areas are often treated as exceptions. Most obstacles met by women in science are difficult to recognize and neutralize because they are deeply informal. Activities for "gender and science" that exceed the limits of sociological study have no long tradition here and are yet finding their place in Estonian society.

    A study was undertaken to examine the content and spatial distribution of fluoride in drinking water. Water samples (735) from public water systems covering all Estonian territory were analysed using SPADNS method. In order to specify the natural source of fluoride, the chemistry data from five aquifer systems utilised for water supply were included into the study. Fluoride concentrations in tap water, to a great extent, ranged from 0.01 to 6.95 mg/l. Drinking water in southern Estonia, where terrigenous Middle-Devonian aquifer system is exploited, has a fluoride concentration lower than recommended level (0.5 mg/l), thus promoting susceptibility to dental caries. The western part of the country is supplied by water with excess fluoride content (1.5-6.9 mg/l). Groundwater abstracted for drinking purposes originates from Ordovician and Silurian carbonate rocks. The content of fluoride in Silurian-Ordovician aquifer system is associated with the groundwater abstraction depth and the main controlling factors of dissolved fluoride are the pH value and the chemical type of water.

  4. Effectiveness of Environmental Impact Assessment system in Estonia

    2010-07-15

    To be effective, an Environmental Impact Assessment (EIA) system, first, has to minimize the probability that projects with significant environmental effects are implemented without EIA, and second, minimize the number of EIAs, which do not provide decision makers with essential information, so that the decision is improved as a result of EIA. The objective of this study was to find out how frequently in Estonia the projects implemented without EIA have caused significant environmental effects, and to measure the relative frequency of EIAs that have no influence on decision. An extensive survey with e-mail distributed questionnaires was carried out to reveal information from governmental agencies, local self-governments, and developers. There was no evidence that projects authorized without EIA have had environmental impacts, which could have been mitigated as a result of EIA. In contrast, about half of EIAs did not alter the decision of relevant authorities. This proportion was valid to both mandatory EIAs and those initiated on judgement basis. In our view, the proportion of no-influence EIAs was excessive and indicated the need to reconsider the provisions applying to the projects with a mandatory EIA requirement as well as judgements practice.

    Hepatitis B virus (HBV) infection is prevalent worldwide and is a significant cause of morbidity and mortality. This article describes the trend in HBV occurrence in Estonia from 1990 to 2005 in Estonia, with the aim of highlighting key determinants in transmission dynamics, risk groups, and possible implications for prevention and control. A marked increase in reported numbers of new HBV cases occurred in mid 1990s (reaching 39 per 100,000 population) and decline thereafter. We present data on HBV prevalence from different population groups (persons with verified sexually transmitted infection, prisoners, medical personnel, blood donors and injection drug users). Special vaccination programmes introduced in Estonia have been successful in the prevention of HBV, however, we suggest that the main risk groups such as injection drug users (IDUs), men having sex with men (MSM) and HIV infected persons should be actively encompassed into HBV vaccination programme.

    This paper reports that Mongolia, formerly the Mongolian People's Republic, is working to open its exploration prospects to international operators as it emerges as the world's 15th largest independent nation. The country, about the same size as Alaska with a population of 2 million, held its first free election in July 1990. The newly elected government drafted a constitution that took effect Feb. 12, 1992. The document modifies the previous government's structures to eliminate bureaucracy and allows for political pluralism. At the same time, the government is formulating energy policies, state oil company structure, and resource development philosophy.

  7. Hospitalised neonates in Estonia commonly receive potentially harmful excipients

    PubMed Central

    2012-01-01

    Background Information on the neonatal exposure to excipients is limited. Our aim was to describe the extent of excipient intake by Estonian neonates; to classify the excipients according to potential neonatal toxicity and thereby to measure the extent of exposure of neonates to potentially harmful excipients. Methods A prospective cohort study that recorded all medicines prescribed to patients aged below 28 days admitted to Tartu University Hospital from 01.02-01.08 2008 and to Tallinn Children’s Hospital from 01.02- 01.08 2009 was conducted. Excipients were identified from Summaries of Product Characteristics and classified according to toxicity following a literature review. Results 1961 prescriptions comprising 107 medicines were written for 348/490 neonates admitted. A total of 123 excipients were found in 1620 (83%) prescriptions and 93 (87%) medicines. 47 (38%) of these excipients were classified as potentially or known to be harmful to neonates. Most neonates (97%) received at least one medicine (median number 2) with potentially or known to be harmful excipient. Parabens were the most commonly used known to be harmful excipients and sodium metabisulphite the most commonly used potentially harmful excipient, received by 343 (99%) and 297 (85%) of treated neonates, respectively. Conclusions Hospitalised neonates in Estonia are commonly receiving a wide range of excipients with their medication. Quantitative information about excipients should be made available to pharmacists and neonatologists helping them to take into account excipient issues when selecting medicines and to monitor for adverse effects if administration of medicines containing excipients is unavoidable.

    Evidence on the cost and cost-effectiveness of treatment of multidrug-resistant tuberculosis (MDR-TB) is limited, and no published data are available from former Soviet Union countries, where rates of MDR-TB are highest globally. We evaluated the cost and cost-effectiveness of MDR-TB treatment in Estonia and Russia (Tomsk Oblast), comparing cohorts enrolled on treatment according to World Health Organization (WHO) guidelines in 2001 and 2002 with cohorts treated in previous years. Costs were assessed from a health system perspective in 2003 US$; effects were measured as cures, deaths averted and disability-adjusted life-years (DALYs) averted. Cure rates when WHO guidelines were followed were 61% (90 out of 149) in Estonia and 76% (76 out of 100) in Tomsk Oblast, with a cost per patient treated of US$8,974 and US$10,088, respectively. Before WHO guidelines were followed, cure rates were 52% in Estonia and 15% in Tomsk Oblast; the cost per patient treated was US$4,729 and US$2,282, respectively. Drugs and hospitalisation accounted for 69-90% of total costs. The cost per DALY averted by treatment following WHO guidelines was US$579 (range US$297-US$902) in Estonia and US$429 (range US$302-US$546) in Tomsk Oblast. Treatment of patients with MDR-TB can be cost-effective, but requires substantial additional investment in tuberculosis control in priority countries. PMID:22362862

  10. Climate change scenarios and the effect of sea-level rise for Estonia

    NASA Astrophysics Data System (ADS)

    Kont, Are; Jaagus, Jaak; Aunap, Raivo

    2003-03-01

    Climate warming due to the enhanced greenhouse effect is expected to have a significant impact on natural environment and human activity in high latitudes. Mostly, it should have a positive effect on human activity. The main threats in Estonia that could be connected with sea-level rise are the flooding of coastal areas, erosion of sandy beaches and the destruction of harbour constructions. Possible climate change and its negative impacts in the coastal regions of Estonia are estimated in this paper. Climate change scenarios for Estonia were generated using a Model for the Assessment of Greenhouse-gas Induced Climate Change (MAGICC) and a regional climate change database—SCENanario GENerator (SCENGEN). Three alternative emission scenarios were combined with data from 14 general circulation model experiments. Climate change scenarios for the year 2100 indicate a significant increase in air temperature (by 2.3-4.5 °C) and precipitation (by 5-30%) in Estonia. The highest increase is expected to take place during winter and the lowest increase in summer. Due to a long coastline (3794 km) and extensive low-lying coastal areas, global climate change through sea-level rise will strongly affect the territory of Estonia. A number of valuable natural ecosystems will be in danger. These include both marine and terrestrial systems containing rare plant communities and suitable breeding places for birds. Most sandy beaches high in recreational value will disappear. However, isostatic land uplift and the location of coastal settlements at a distance from the present coastline reduce the rate of risk. Seven case study areas characterising all the shore types of Estonia have been selected for sea-level rise vulnerability and adaptation assessment. Results and estimates of vulnerability to 1.0-m sea-level rise by 2100 are presented in this paper. This is the maximum scenario according to which the actually estimated relative sea-level rise would vary from 0.9 m (SW Estonia) to 0

  11. Revegetation processes and environmental conditions in abandoned peat production fields in Estonia

    2009-04-01

    As a result of peat extraction, peat production has been finished in Estonia at different times in 154 peat production areas and 9,500 ha (~1% of peatlands) are abandoned, although the peat reserves are not exhausted yet; besides, several areas are not properly recultivated. In addition 12,000 ha of fens (oligotrophic peat layers) are drained and used as grasslands. If the abandoned and non-recultivated peat production areas are not vegetated, their CO2 emission is considerable and peat mineralises in such areas. The aim of the study was to find out specific ecological and geological factors, which affect recovering of peatlands and influence the recultivation. During the revision the amount and quality of the remained reserves, as well as the state of water regime, drainage network and revegetation was assessed in all 154 abandoned peat production areas. The study showed that the state of them is very variable. Some of them are covered with forest, prevailingly with birches at former drainage ditches, later supplemented by pine trees. In the others predominate grasses among plants, and various species of moss (Cladonia rei, Bryum caespiticum, Sphagnum ripariuma, Sphagnum squarrosum) occur as well. Besides, some abandoned areas are completely overgrown with cotton grass. Open abandoned peat areas, which are not covered by vegetation, are much rarer. We found out, that water regime among the factors plays most important role. Moreover abandoned peat production fields, where the environmental conditions have changed - are appropriate for growth of several moss species, which cannot inhabit the areas already occupied by other species. The most interesting discovers were: second growing site of Polia elongata in West-Estonia and Ephemerum serratum, last found in Estonia in the middle of the 19th century, was identified in central Estonia. Also Campylopus introflexus, what was unknown in Estonia. However, the changes in environmental conditions influence the peat layers

    The continued identification of new low-penetrance genetic variants for colorectal cancer (CRC) raises the question of their potential cumulative effect among compound carriers. We focused on 6 SNPs (rs380284, rs4464148, rs4779584, rs4939827, rs6983267, and rs10795668), already described as risk markers, and tested their possible independent and combined contribution to CRC predisposition. Material and Methods. DNA was collected and genotyped from 2330 unselected consecutive CRC cases and controls from Estonia (166 cases and controls), Latvia (81 cases and controls), Lithuania (123 cases and controls), and Poland (795 cases and controls). Results. Beyond individual effects, the analysis revealed statistically significant linear cumulative effects for these 6 markers for all samples except of the Latvian one (corrected P value = 0.018 for the Estonian, corrected P value = 0.0034 for the Lithuanian, and corrected P value = 0.0076 for the Polish sample). Conclusions. The significant linear cumulative effects demonstrated here support the idea of using sets of low-risk markers for delimiting new groups with high-risk of CRC in clinical practice that are not carriers of the usual CRC high-risk markers.

Using survey data from nationally representative samples from Finland in 1971, 1992, and 1999 and from two former Soviet areas, Estonia in 2000 and St. Petersburg in 1996, we investigated the following: (a) differences across decades and countries in acceptance of the sexual double standard (SDS) in attitudes toward marital infidelity and women's initiating sex; and (b) the relationship between the SDS and sexual satisfaction. Results show that Finland in the 1990s was more egalitarian than Finland in 1971, St. Petersburg in 1996, or Estonia in 2000. Egalitarian sexual attitudes were positively related to sexual satisfaction.

    The earliest Osprioneides kampto borings were found in bryozoan colonies of Sandbian age from northern Estonia (Baltica). The Ordovician was a time of great increase in the quantities of hard substrate removed by single trace makers. Increased predation pressure was most likely the driving force behind the infaunalization of larger invertebrates such as the Osprioneides trace makers in the Ordovician. It is possible that the Osprioneides borer originated in Baltica or in other paleocontinents outside of North America. PMID:24901511

    Although sheep (Ovis aries) have been one of the most exploited domestic animals in Estonia since the Late Bronze Age, relatively little is known about their genetic history. Here, we explore temporal changes in Estonian sheep populations and their mitochondrial genetic diversity over the last 3000 years. We target a 558 base pair fragment of the mitochondrial hypervariable region in 115 ancient sheep from 71 sites in Estonia (c. 1200 BC–AD 1900s), 19 ancient samples from Latvia, Russia, Poland and Greece (6800 BC–AD 1700), as well as 44 samples of modern Kihnu native sheep breed. Our analyses revealed: (1) 49 mitochondrial haplotypes, associated with sheep haplogroups A and B; (2) high haplotype diversity in Estonian ancient sheep; (3) continuity in mtDNA haplotypes through time; (4) possible population expansion during the first centuries of the Middle Ages (associated with the establishment of the new power regime related to 13th century crusades); (5) significant difference in genetic diversity between ancient populations and modern native sheep, in agreement with the beginning of large-scale breeding in the 19th century and population decline in local sheep. Overall, our results suggest that in spite of the observed fluctuations in ancient sheep populations, and changes in the natural and historical conditions, the utilisation of local sheep has been constant in the territory of Estonia, displaying matrilineal continuity from the Middle Bronze Age through the Modern Period, and into modern native sheep.

    The purpose of this study was to assess exposure to drinking water fluoride and evaluate the risk of dental fluorosis among the Estonian population. The study covered all 15 counties in Estonia and 93.7% of population that has access to public water supplies. In Estonia groundwater is the main source for public water supply systems in most towns and rural settlements. The content of natural fluoride in water ranges from 0.01 to 7.20 mg/L. The exposure to different fluoride levels was assessed by linking data from previous studies on drinking water quality with databases of the Health Protection Inspectorate on water suppliers and the number of water consumers in water supply systems. Exposure assessment showed that 4% of the study population had excessive exposure to fluoride, mainly in small public water supplies in western and central Estonia, where the Silurian-Ordovician aquifer system is the only source of drinking water. There is a strong correlation between natural fluoride levels and the prevalence of dental fluorosis. Risk of dental fluorosis was calculated to different fluoride exposure levels over 1.5 mg/L.

    Fluoride is a naturally occurring contaminant in groundwater in Estonia. There are several regions in Estonia with fluoride contents in public water supplies as high as 7 mg/L. Long-term exposure to high-fluoride drinking water may have several adverse health effects, primarily dental fluorosis. The opportunities for exposure reduction rely highly on water treatment technologies. Since 2004 public water suppliers in Estonia have made efforts to diminish fluoride content in drinking water systems. A follow-up study on a country level was carried out in 2004-2012 to analyze the changes in population exposure to excessive (over 1.5 mg/L) fluoride in drinking water and to get information about the reduction methods applied by public water supplies (PWS) to optimize the fluoride levels in public water system. The results showed that bigger PWS have been more effective in fluoride reduction measures than small PWS. The main methods used to lower the fluoride content were reverse osmosis technology and replacement of water sources with new ones (new drilled wells). As a result of all the measures taken the overall high-fluoride exposure has been reduced substantially (82%).

    In order to perform any Bayesian processing of a model ensemble, we need a prior over the ensemble members. In the case of multimodel ensembles such as CMIP, the historical approach of ``model democracy'' (i.e. equal weight for all models in the sample) is no longer credible (if it ever was) due to model duplication and inbreeding. The question of ``model independence'' is central to the question of prior weights. However, although this question has been repeatedly raised, it has not yet been satisfactorily addressed. Here I will discuss the issue of independence and present a theoretical foundation for understanding and analysing the ensemble in this context. I will also present some simple examples showing how these ideas may be applied and developed.

    International guidelines developed recommendations in the resuscitation of the new-born: at least one person trained in resuscitation of the newly born should attend every delivery. A minority of the new-borns require active resuscitation to achieve regular respiration, heart rhythm above 100/min, pink colour and adequate tone. Establishment of adequate ventilation should be of primary concern. Most new-borns who require positive-pressure ventilation can be adequately ventilated with a bag and mask. All healthcare providers, who may be asked to deal with an emergency delivery, should master such technique. In case of meconium-stained amniotic fluid, thorough oropharyngeal suctioning should be perform before the delivery of the chest. Tracheal aspiration of mecomium should be perform only in depressed child. Very few infants require chest compressions and much less administration of drugs. Umbilical access remains the most widely recommended access in new-born. Adequate transfer to Neonatal Unit improves outcome. PMID:12503356

    The paper describes a deposit of natural amber found form Estonia. Finds of natural amber are important in the context of the Bronze Age archaeology, because the amount of Bronze Age archaeological amber found in Estonia is very small. Most of the amber is from the Late Bronze Age and is mainly discovered from the fortified settlements in Saaremaa, some also from burials of the same time. Now, the discovery of the deposit of natural amber in the island of Saaremaa makes us reconsider the general opinion that all archaeological amber items found in Estonia have been imported. The aim of this study is to clarify the origin and age of the natural amber using scientific methods. A layer of buried organic matter (BOM) containing pieces of natural amber was discovered in Holocene coastal plain on Sõrve peninsula, island of Saaremaa. The BOM layer is buried under ca 90 cm-thick sandy coastal deposits and consists of remains of coastal plants and pieces of driftwood. Palaeogeographic reconstructions and sediment composition indicate that the layer was deposited in the coastal zone and buried quickly by sandy marine sediments. According to radiocarbon dating of the seeds of Polygonum lapathifolium the formation of the BOM layer remained in the Late Bronze Age (2480 ± 30 14C yr BP). Amber finds have been characterized using ATR-FTIR spectroscopy and isotope analysis of light elements (H and C) - both are referring to Baltic amber. Therefore it is probable that amber was transported to Saaremaa within organic matter from the Latvian-Lithuanian coastal zone where secondary Baltic amber deposits are widely known.

    Estonia regained independence in 1991 after five decades of occupation by the Soviet Union. The present population-based survey was carried out over five consecutive 5-year study periods (1982-2006) on the incidence and survival of de novo acute leukemia patients aged ≥65 years at diagnosis in Estonia and in a well-defined area in western Sweden. During the study period of retrospective work (1982-1996), the first 10 years were carried out while Estonia was still under the mentorship of the Soviet Union. Over these years, Estonian hematologists did not have access to therapeutic measures readily available to Swedish hematologists, and the results for survival for western Swedish patients with acute myeloid leukemia (AML) far exceeded those of their Estonian counterparts. However, the results for acute lymphoblastic leukemia were equally dismal in the two countries. Subsequent prospective population-based studies were carried out during the years 1997-2006. A gradual improvement as to long-term relative survival of the Estonian AML patients was observed. When studying 2002-2006, no difference as regards relative survival at 5 years was anymore present between the two countries. Over the first 20 years of our population-based studies, it was repeatedly observed that the age-standardized incidence rate particularly for de novo AML was considerably higher for the western Swedish as compared to the Estonian cohorts. During the last 5-year study period (2002-2006), no such difference between the two countries was present, indicating that some true changes in the reporting procedure in Estonia had occurred.

    The Island of Saaremaa in Estonia offers highly spectacular geological features that belong to the most interesting in the Baltic Sea area. A unique geological monument on the island is the Kaali meteorite-crater field, formed by nine meteorite impacts. There are also attractive coastal cliffs, huge erratics, alvars (limestone areas covered by a very thin soil) and well-developed glacial and marine landforms. Limestone cliffs and shingle beaches abound with Silurian fossils and offer great opportunities to fossil collectors. The island is a prospective geopark. During the past few years, the geology of the island has become an intensely studied object of Estonian and Polish geologists.

    The Atlantic meridional overturning circulation represents the strongest mechanism for oceanic northward heat transport. This is accomplished by moving warm water northward in the upper ocean compensated by a deep return flow of cold and dense North Atlantic Deep Water (NADW). Labrador Sea Water (LSW) constitutes the shallowest component of NADW. Since LSW is also supposed to be the most sensitive NADW component to climate change it is of particular interest. LSW is formed by deep convection not only in the centre of the Labrador Sea but also near its western boundary. Recent studies have suggested that LSW formed in the boundary region enters its export route from the Labrador Sea, the Deep Western Boundary Current, faster than LSW originating from the central Labrador Sea. In this study the spatial and temporal evolution of the export of newly formed LSW is investigated. For this purpose hydrographic mooring data from an array located at the western bounndary at 53°N starting in the late 1990s until 2014 and data from the Argo float network is used. The averaged seasonal salinity cycle at the array, particularly at the moorings further onshore, shows a pronounced freshwater signal in May indicating the arrival of newly formed LSW in the boundary current. In order to learn more about its preceding pathway and the corresponding export timescale the mooring data is complemented by data from Argo floats. Besides the annual cycles of LSW formation and export, their interannual variations are important aspects affecting the large-scale circulation. For instance, in years of relatively strong convection, as in 2008 and 2012, LSW is observed to pass the boundary current array at 53°N earlier, i.e. in February and March, respectively, than in years with weak convection, as in 2007 or 2010. Besides seasonal variations in the boundary current, a possible explanation for the earlier freshwater signal in years of enhanced convection might be a shift in convection sites

    The transition from living a life as others want (dependence) to living it as the adolescent wants to live it (independence) is extraordinarily difficult for most teen-agers and their families. The difficulty is compounded in the case of adolescents with disabilities. They are often denied access to the same opportunities of life that are accessible to the nondisabled. They face special problems in augmenting their inherent capacities so that they can take fuller advantage of the accommodations that society makes in an effort to grant them access. In particular, they need training designed to increase their capacities to make, communicate, implement, and evaluate their own life-choices. The recommendations made in this paper are grounded in the long-standing tradition of parens patriae and enlightened paternalism; they seek to be deliberately and cautiously careful about the lives of adolescents with disabilities and their families. We based them on the recent tradition of anti-institutionalism and they are also consistent with some of the major policy directions of the past 15-20 years. These include: normalization, integration, and least-restrictive alternatives; the unity and integrity of the family; the importance of opportunities for self-advocacy; the role of consumer consent and choice in consumer-professional relationships; the need for individualized services; the importance of the developmental model as a basis for service delivery; the value of economic productivity of people with disabilities; and the rights of habilitation, amelioration, and prevention.

    A survey on trichinellosis among sylvatic and domestic animals from Estonia revealed the presence of Trichinella nativa (Tn), Trichinella britovi (Tb), and Trichinella spiralis (Ts). Muscle samples were collected from 776 sylvatic and 1,086 domestic animals. Muscle larvae from 52 of the 74 positive samples were identified, using random-amplified polymorphic DNA analysis; 19 samples showed Tn, 27 samples Tb, and 4 samples Ts. A raccoon dog (Nyctereutes procyonoides) and a red fox (Vulpes vulpes) were infected with both Tn and Tb. Of the 19 animals infected with Tn, 16 (84%) were collected from the central-eastern regions of the country, east of the isotherm -5 C in January. Of the 27 animals infected with Tb, 22 (81%) were collected from the western regions of the country, west of the isotherm -4 C in January. Trichinella spiralis seemed to be present only in a focus (a fur-bearing animal farm) on Hiiumaa Island. These results can be used to support the hypothesis of a relationship between the distribution of Tn and Tb and the environmental temperature; they are also indicative of the importance of long-term survival of muscle larvae in host carcasses in the life cycle of these 2 species. In Estonia, the isotherms -4 and -6 C in January could be considered a thermic barrier for the distribution of Tn and Tb, respectively. PMID:9488368

    Here we consider cost-effective solutions of emission control measures in Finland and the nearby areas of Estonia, St. Petersburg region, Karelia and Kola, in order to limit the acidifying deposition in Finland. In the study, the emission control costs of SO2, NOx and NH3 are assessed for the areas studied and an optimisation model developed for calculation of cost-optimal deposition control policies. The input data of the model consist of the cost functions describing the emission control costs to achieve lower emission levels for the gases and areas considered and of dispersion coefficients which describe the deposition due to an emission source in the deposition receptor grid squares. In addition, the model includes a description to calculate the acidifying load. The optimisation is based on linear programming. When the acidifying load of Southern Finland is reduced by minimising the total control costs, approx, three quarters of the total control costs are due to measures in the nearby areas, Estonia, St. Peterburg region, Karelia and Kola, and approx. one quarter due to measures in Finland. The distribution of costs in the cost-optimised cases depends relatively little on the level to which the acidifying load due the source areas considered are required to be reduced. If the load reduction target is moderate, the emission control measures should mainly be allocated to sulphur emissions and to some extent to ammonia emissions and, if the load reduction target is stricter, also to the emissions of nitrogen oxides.

    The importance of tightness-looseness as a dimension that explains a considerable amount of variance between cultures was demonstrated by Gelfand et al. (2011). Tight nations have many strong norms and a low tolerance of deviant behaviour, whereas loose nations have weak social norms and a high tolerance of deviant behaviour. The main aim of the current studies was to examine situational constraint in Estonia and Greece: that is, how the cultural dimension of tightness-looseness is manifested in everyday situations in those two countries. The findings of a questionnaire study (Study 1) suggested that, in general, there is higher constraint across everyday situations in Greece than in Estonia, but situational constraint in Greece is especially strong in school and organisational settings where people have hierarchically structured roles. The results of an observational study (Study 2) revealed a relatively high agreement between appropriateness of certain behaviours as judged by the respondents in Study 1 and the frequencies of observed behaviours in the two countries. Our findings suggest that the strength of situations may substantially vary both within and across cultures, and that the attitudes of the members about situational strength in their respective cultures are in concordance with observations of situations by neutral observers in how people in general behave in their culture.

    The earliest bioeroded inorganic hard substrates in the Ordovician of Estonia appear in the Dapingian. Hardgrounds are also known from the Sandbian and Katian. Most of the bioerosion of inorganic hard substrates occurs as the boring Trypanites Mägdefrau, 1932 along with some possible Gastrochaenolites borings. North American hardground borings are more diverse than those in Baltica. In contrast to a worldwide trend of increasing boring intensity, the Estonian record seems to show no increase in boring intensities during the Middle and Late Ordovician. Hardgrounds seem to be more common during the temperate climate interval of the Ordovician calcite sea in Estonia (seven hardgrounds during 15 my) than in the part with a tropical climate (four hardgrounds during 12 my). Bioerosion is mostly associated with carbonate hardgrounds, but cobbles and pebbles broken from the hardgrounds are also often penetrated by Trypanites borings. The general diversity of boring ichnotaxa in Baltica increased from one ichnospecies in the Cambrian to seven by the end of Ordovician, showing the effect of the GOBE on bioeroding ichnotaxa. The diversity of inorganic hard substrate borers increased by only two times. This difference can be explained by the wider environmental distribution of organic as compared to inorganic substrates in the Ordovician seas of Baltica, and their more continuous temporal availability, which may have caused increased specialization of several borers. The inorganic substrates may have been bioreroded only by the generalists among boring organisms. PMID:26218582

    Anaplasma phagocytophilum is associated with diseases of goats, sheep, cattle, dogs and horses. In the beginning of the 1990s it was identified as a human pathogen, causing human granulocytic anaplasmosis (HGA) in the USA, Europe and the far east of Russia. A. phagocytophilum is maintained in nature in an enzootic cycle including ticks as the main vector and a wide range of mammalian species as reservoirs. Ixodes ricinus and I. persulcatus ticks were collected in Estonia, Belarus and the European part of Russia and screened for the presence of A. phagocytophilum by real-time PCR. Positive samples were found only among I. ricinus, in 13.4% in the European part of Russia, 4.2% in Belarus, 1.7% in mainland Estonia and 2.6% on Saaremaa Island. Positive samples were sequenced for partial 16S rRNA, groESL and ankA genes and phylogenetic analyses were performed. The results showed that A. phagocytophilum circulating in Eastern Europe belongs to different groESL lineages and 16S rRNA gene variants and also consists of variable numbers of repetitive elements within the ankA gene.

    This article is part of a long term project "Promoting the Occupational Well-Being of School Staff-Action Research Project in Finland and Estonia, 2009-2014." The purpose of this article is to describe the significance of action plans in the promotion of the occupational well-being of primary and upper secondary school staff in Finland and Estonia from 2010 to the turn of the year 2011-2012. An electronic open questionnaire was sent to occupational well-being groups in Finland (N=18) and in Estonia (N=39). In Finland, the questionnaire was responded to by 16 (n=16) occupational well-being groups, and in Estonia, by 38 (n=38) groups. The qualitative data were analyzed using the inductive-deductive method and content analysis. The obtained results indicate that the schools had named goals for action plans in all aspects of the promotion of occupational well-being in schools (worker and work, working conditions, professional competence, working community) and that these goals were mainly realized in the schools in a systematic way. Schools felt that the action plan for occupational well-being helped them to set goals for occupational well-being and that the planned actions were realized in a more systematic way than before.

    Congenital heart defects (CHD) occur in 8 per 1000 live births. If they remain untreated, 70-80% of these patients die in early childhood. With modern diagnostic and treatment procedures, 90% of these patients reach adulthood. Within 8 years following reunification of Germany, it was possible to improve treatment for CHD in former East Germany to West German standards. Based on the experience gained in this process, a plan for improvement of care of Estonian patients with CHD was developed and implemented in the German-Estonian project, "Partnership for the Heart". The main elements of the project were (1) the training of Estonian physicians in Germany, (2) training courses conducted by German and Estonian specialists in Estonia and (3) use of telemedicine for consultation on a continuous basis. During the project 15 Estonian patients underwent cardiac surgery and/or catheter interventions performed by a joint team of German and Estonian specialists. The infant mortality due to CHD in Estonia fell by 28% during the project period. Key techniques of cardiac surgery are now being employed in Estonia without outside support, indicating the success of the training program and the long-term improvements to cardiac health care in Estonia. The total project costs were 314,252 Euro (euro), which is 50% lower than the estimated cost of treating the 15 patients abroad in Western Europe. The structure of "Partnership for the Heart" and the modified self-sufficiency model of medical care have not only produced results for Estonia but can be taken as a template for future bilateral health projects with other transition countries and for other fields of medical specialisation, and thus might aid a European health policy.

    There is substantial evidence supporting the role of certain oral bacteria species in the onset and progression of periodontitis. Nevertheless, results of independent-culture diagnostic methods introduced about a decade ago have pointed to the existence of new periodontal pathogens. However, the data of these studies have not been evaluated together, which may generate some misunderstanding on the actual role of these microorganisms in the etiology of periodontitis. The aim of this systematic review was to determine the current weight of evidence for newly identified periodontal pathogens based on the results of “association” studies. This review was conducted and reported in accordance with the PRISMA statement. The MEDLINE, EMBASE, and Cochrane databases were searched up to September 2013 for studies (1) comparing microbial data of subgingival plaque samples collected from subjects with periodontitis and periodontal health and (2) evaluating at least 1 microorganism other than the already-known periodontal pathogens. From 1,450 papers identified, 41 studies were eligible. The data were extracted and registered in predefined piloted forms. The results suggested that there is moderate evidence in the literature to support the association of 17 species or phylotypes from the phyla Bacteroidetes, Candidatus Saccharibacteria, Firmicutes, Proteobacteria, Spirochaetes, and Synergistetes. The phylum Candidatus Saccharibacteria and the Archaea domain also seem to have an association with disease. These data point out the importance of previously unidentified species in the etiology of periodontitis and might guide future investigations on the actual role of these suspected new pathogens in the onset and progression of this infection.

We sought to identify a feasible adherence support intervention for delivery amongst HIV-positive adults receiving care in Estonia, where the HIV/AIDS epidemic has been mainly concentrated among injection drug users (IDUs). Our application of intervention mapping (IM) strategies used existing literature, formative research and multidisciplinary team input to produce a brief clinic-based intervention entitled the Situated Optimal Adherence Intervention Estonia (sOAI Estonia) which uses both Next-Step Counseling (NSC) and Information-Motivation-Behavioral Skills (IMB) Model approach to facilitate integration of ART into the context and demands of daily life. We present the intervention development process, the resulting sOAI Estonia approach, and describe a randomized controlled trial (RCT) which is under way to evaluate the intervention (results due in spring 2013).

    The aim of the present study was to investigate the content of total carotenoids in different collections of pot marigold (Calendula officinalis L.) inflorescences. Commercial seeds (42 samples) of C. officinalis were obtained from nine countries and cultivated in private gardens in three different counties of Estonia. The content of total carotenoids, determined spectrophotometrically (lambda=455 nm) varied in the investigated collections from 0.20 to 3.51%. The amount of pigments may depend on the type of plants, the importing company, the color of the ligulate and tubular florets, and the place and time of cultivation. For medicinal purposes, C. officinalis with brownish-yellow ligulate and tubular florets should be preferred. The best was found to be 'Golden Emperor' from Finland. PMID:19370871

    Three structures (Neugrund, Kärdla, and Kaali) of proven impact origin make Estonia the most cratered country in the world by area. In addition, several candidate impact structures exist, waiting for future studies to determine their origin. This article is an overview of these proven and possible impact structures, including some breccia layers. It summarizes the information and descriptions of the morphology; geological characteristics; and mineralogical, chemical, and geophysical data available in the literature. The overview was prepared to make information in many earlier publications in local journals (many of which had been published in Estonian or Russian) accessible to the international community. This review summarizes the facts and observations in a historical fashion, summarizing the current state of knowledge with some additional comments, and providing the references.

    HIV and sexually transmitted infections (STI) testing rates among men who have sex with men (MSM) in Estonia are low. We collected data from 265 MSM in a national, online survey. Lifetime HIV testing was related to risky sexual behaviors and contacts with health care services, while lifetime STI testing was related only to contacts with health care services. In addition, some personal values were significant predictors of testing. For example, high achievement (personal success through demonstrating competence according to social standards) had a negative impact on lifetime HIV testing, and high interpersonal conformity (avoiding upsetting others) had a negative impact on lifetime STI testing. The results demonstrate the need to develop gay-friendly health services and to recognize the role of personal values and individual differences in values when designing attractive interventions to increase HIV/STI testing rates among MSM.

    The present study focused on the identification of emotions in cross-cultural conditions on different continents and among subjects with divergent language backgrounds. The aim was to investigate whether the perception of the basic emotions from nonsense vocal samples was universal, dependent on voice quality, musicality, and/or gender. Listening tests for 350 participants were conducted on location in a variety of cultures: China, Egypt, Estonia, Finland, Russia, Sweden, and the USA. The results suggested that the voice quality parameters played a role in the identification of emotions without the linguistic content. Cultural background may affect the interpretation of the emotions more than the presumed universality. Musical interest tended to facilitate emotion identification. No gender differences were found.

    Since the early 1990s, major reform in healthcare has been adopted in former communist countries in Central and Eastern Europe. More than 20 years after, reform in healthcare still draws much interest from policy makers and academics alike. One of the dynamic components of reform has been the reform of payment systems in primary care. This article looks at recent developments in payment systems and financial incentives in Estonia and Romania. We conclude that finding the appropriate mix in paying and incentivizing primary care providers in a transitional context is no easy solution for healthcare policy makers who need to carefully weigh in the advantages and inherent problems of various payment arrangements. In a transitional, rapidly changing healthcare system and society, and a context of financial stringency, the theoretical effects of payment mechanisms may be more difficult to predict and manage than it is expected.

  3. On Connections Between Weather Types and the Arrival of Migratory Birds in Estonia

    Migration is one of the most energy-consuming activities in the lives of birds. The timing must be such that flying would not be overly strenuous and that there would be favourable conditions for feeding and nesting available at arrival. The wide year-to-year variation in the arrival dates of migratory birds suggests that birds are able to both accelerate and delay their migration according to the weather conditions in the destination area. Often, the arrival date cannot be explained by the average daily temperature or any other single meteorological parameter. Relatively simple tools for exploring the links between climate and wildlife are weather types that combine most of the meteorological variables. The aim of the present work is to study the connections between the arrival of migratory birds in Estonia and the weather types. We examine the weather types that most frequently occurred on those days when birds arrived in Tartu (located in the Eastern part of Estonian mainland) and in Kuressaare (West-Estonian archipelago). For this purpose, the arrival dates of 42 species of migratory birds were analysed and compared to the weather types of 73 classifications generated by COST 733 action (COST 733 catalogue 1.2). Since the weather type classifications were generated using ERA40 air pressure datasets, the period available for analysis is 1958-2002. We selected weather types that occurred on the arrival dates of each migratory bird species. Also, the data on two days prior to the arrival were analysed. We assume that birds "took the decision" to fly to Estonia due to the weather conditions on those two days. Frequency of the selected weather types was analysed and compared to the long term frequency of these types during the spring season (MAM). We assume that birds "prefer" those weather types whose frequency on migration days exceeds their long-term frequency. Similarly, we studied the weather types that birds seem to avoid. The results show that despite the

    In the Telychian section of Estonia and Latvia K-bentonites from 45 volcanic eruptions were discovered. The thickness of K-bentonite interbeds varies from a few millimetres to 20 cm. The sodium component concentration in sanidine phenocrysts measured by XRD ranges from 20 to 48 mol% and was used for establishing correlations. The Ti, Zr, Nb, Th and Sr concentrations and ratios show temporal trends indicating fractional crystallization in magma chambers. The analysis of biotite phenocrysts revealed magnesium and iron rich biotites in bentonites. Synthesis of these geochemical data enabled a classification of bentonites into seven geochemical types, which probably originate from seven different volcanic sources. Isopach schemes indicate ash transport from the west and north-west directions.

    All post-Soviet countries are trying to reform their primary health care (PHC) systems. The success to date has been uneven. We evaluated PHC reforms in Estonia, using multimethods evaluation: comprising retrospective analysis of routine health service data from Estonian Health Insurance Fund and health-related surveys; documentary analysis of policy reports, laws and regulations; key informant interviews. We analysed changes in organisational structure, regulations, financing and service provision in Estonian PHC system as well as key informant perceptions on factors influencing introduction of reforms. Estonia has successfully implemented and scaled-up multifaceted PHC reforms, including new organisational structures, user choice of family physicians (FPs), new payment methods, specialist training for family medicine, service contracts for FPs, broadened scope of services and evidence-based guidelines. These changes have been institutionalised. PHC effectiveness has been enhanced, as evidenced by improved management of key chronic conditions by FPs in PHC setting and reduced hospital admissions for these conditions. Introduction of PHC reforms - a complex innovation - was enhanced by strong leadership, good co-ordination between policy and operational level, practical approach to implementation emphasizing simplicity of interventions to be easily understood by potential adopters, an encircling strategy to roll-out which avoided direct confrontations with narrow specialists and opposing stakeholders in capital Tallinn, careful change-management strategy to avoid health reforms being politicized too early in the process, and early investment in training to establish a critical mass of health professionals to enable rapid operationalisation of policies. Most importantly, a multifaceted and coordinated approach to reform - with changes in laws; organisational restructuring; modifications to financing and provider payment systems; creation of incentives to enhance

  7. Variation of atmospheric air pollution under conditions of rapid economic change—Estonia 1994-1999

    NASA Astrophysics Data System (ADS)

    Kimmel, V.; Tammet, H.; Truuts, T.

    Estonia is an example of a country with economy in transition whose atmospheric air pollution has been remarkably influenced by economic changes. During the period of 1994-1999 GDP increased by one-fourth, while agricultural production, electricity and heat production dropped by one-sixths during the studied period. These processes are reflected in the quantity of emissions and structure of air pollution. The study is based on the measurements of concentrations of pollutants at six Estonian Euroairnet monitoring stations—at three sites in the capital city and at three sites in remote areas. The pollutants concerned are the first-priority pollutants in the European Union legislation—nitrogen oxides, SO 2, O 3, particulate matter, and additionally CO. The study reveals that concentrations of gaseous pollutants in Estonia remain within the EU limit values except for ozone in remote areas. The main trend during the studied period was a significant, up to several times, decrease in concentrations of SO 2 and CO while the decrease of nitrogen oxides was less remarkable. The paper propose ratio of NO x/SO 2 as an index describing increasing transport loads and drop in use of sulphur-rich fuels—thus of structure of economy. The annual variation of pollutants is explained by seasonal variations of anthropogenic activity in conditions where local fuels are widely used for heating during winter. Air pollution in Estonian rural stations mostly originated from transboundary fluxes. The 1-3 day delay of the weekly minimum of pollutant concentrations and the wind roses allow to conclude that essential part of pollutants is imported from West Europe.

  8. The occurrence and hydrochemistry of fluoride and boron in carbonate aquifer system, central and western Estonia.

    Silurian-Ordovician (S-O) aquifer system is an important drinking water source of central and western Estonia. The fluoride and boron contents of groundwater in aquifer system vary considerably. The fluoride concentration in 60 collected groundwater samples ranged from 0.1 to 6.1 mg/l with a mean of 1.95 mg/l in the study area. Boron content in groundwater varied from 0.05 mg/l to 2.1 mg/l with a mean value of 0.66 mg/l. Considering the requirements of EU Directive 98/83/EC and the Estonian requirements for drinking water quality, the limit value for fluoride (1.5 mg/l) and for boron (1.0 mg/l) is exceeded in 47 and 28 % of wells, respectively. Groundwater with high fluoride and boron concentrations is found mainly in western Estonia and deeper portion of aquifer system, where groundwater chemical type is HCO3-Cl-Na-Mg-Ca, water is alkaline, and its Ca(2+) content is low. Groundwater of the study area is undersaturated with respect to fluorite and near to equilibrium phase with respect to calcite. The comparison of TDS versus Na/(Na + Ca) and Cl/(Cl + HCO3) points to the dominance of rock weathering as the main process, which promotes the availability of fluoride and boron in the groundwater. The geological sources of B in S-O aquifer system have not been studied so far, but the dissolution of fluorides from carbonate rocks (F = 100-400 mg/kg) and K-bentonites (F = 2,800-4,500 mg/kg) contributes to the formation of F-rich groundwater.

  9. Expanded syringe exchange programs and reduced HIV infection among new injection drug users in Tallinn, Estonia

    2011-01-01

    Background Estonia has experienced an HIV epidemic among intravenous drug users (IDUs) with the highest per capita HIV prevalence in Eastern Europe. We assessed the effects of expanded syringe exchange programs (SEP) in the capital city, Tallinn, which has an estimated 10,000 IDUs. Methods SEP implementation was monitored with data from the Estonian National Institute for Health Development. Respondent driven sampling (RDS) interview surveys with HIV testing were conducted in Tallinn in 2005, 2007 and 2009 (involving 350, 350 and 327 IDUs respectively). HIV incidence among new injectors (those injecting for < = 3 years) was estimated by assuming (1) new injectors were HIV seronegative when they began injecting, and (2) HIV infection occurred at the midpoint between first injection and time of interview. Results SEP increased from 230,000 syringes exchanged in 2005 to 440,000 in 2007 and 770,000 in 2009. In all three surveys, IDUs were predominantly male (80%), ethnic Russians (>80%), and young adults (mean ages 24 to 27 years). The proportion of new injectors decreased significantly over the years (from 21% in 2005 to 12% in 2009, p = 0.005). HIV prevalence among all respondents stabilized at slightly over 50% (54% in 2005, 55% in 2007, 51% in 2009), and decreased among new injectors (34% in 2005, 16% in 2009, p = 0.046). Estimated HIV incidence among new injectors decreased significantly from 18/100 person-years in 2005 and 21/100 person-years in 2007 to 9/100 person-years in 2009 (p = 0.026). Conclusions In Estonia, a transitional country, a decrease in the HIV prevalence among new injectors and in the numbers of people initiating injection drug use coincided with implementation of large-scale SEPs. Further reductions in HIV transmission among IDUs are still required. Provision of 70 or more syringes per IDU per year may be needed before significant reductions in HIV incidence occur.

We evaluated PHC reforms in Estonia, using multimethods evaluation: comprising retrospective analysis of routine health service data from Estonian Health Insurance Fund and health-related surveys; documentary analysis of policy reports, laws and regulations; key informant interviews. We analysed changes in organisational structure, regulations, financing and service provision in Estonian PHC system as well as key informant perceptions on factors influencing introduction of reforms. Estonia has successfully implemented and scaled-up multifaceted PHC reforms, including new organisational structures, user choice of family physicians (FPs), new payment methods, specialist training for family medicine, service contracts for FPs, broadened scope of services and evidence-based guidelines. These changes have been institutionalised. PHC effectiveness has been enhanced, as evidenced by improved management of key chronic conditions by FPs in PHC setting and reduced hospital admissions for these conditions. Introduction of PHC reforms - a complex innovation - was enhanced by strong leadership, good co-ordination between policy and operational level, practical approach to implementation emphasizing simplicity of interventions to be easily understood by potential adopters, an encircling strategy to roll-out which avoided direct confrontations with narrow specialists and opposing stakeholders in capital Tallinn, careful change-management strategy to avoid health reforms being politicized too early in the process, and early investment in training to establish a critical mass of health professionals to enable rapid operationalisation of policies. Most importantly, a multifaceted and coordinated approach to reform - with changes in laws; organisational restructuring; modifications to financing and provider payment systems; creation of incentives to enhance

    Silurian-Ordovician (S-O) aquifer system is an important drinking water source of central and western Estonia. The fluoride and boron contents of groundwater in aquifer system vary considerably. The fluoride concentration in 60 collected groundwater samples ranged from 0.1 to 6.1 mg/l with a mean of 1.95 mg/l in the study area. Boron content in groundwater varied from 0.05 mg/l to 2.1 mg/l with a mean value of 0.66 mg/l. Considering the requirements of EU Directive 98/83/EC and the Estonian requirements for drinking water quality, the limit value for fluoride (1.5 mg/l) and for boron (1.0 mg/l) is exceeded in 47 and 28 % of wells, respectively. Groundwater with high fluoride and boron concentrations is found mainly in western Estonia and deeper portion of aquifer system, where groundwater chemical type is HCO3-Cl-Na-Mg-Ca, water is alkaline, and its Ca(2+) content is low. Groundwater of the study area is undersaturated with respect to fluorite and near to equilibrium phase with respect to calcite. The comparison of TDS versus Na/(Na + Ca) and Cl/(Cl + HCO3) points to the dominance of rock weathering as the main process, which promotes the availability of fluoride and boron in the groundwater. The geological sources of B in S-O aquifer system have not been studied so far, but the dissolution of fluorides from carbonate rocks (F = 100-400 mg/kg) and K-bentonites (F = 2,800-4,500 mg/kg) contributes to the formation of F-rich groundwater.

    The Francis report highlighted the importance of strong leadership from health professionals but it is unclear how prepared those who are newly qualified feel to take on a leadership role. We aimed to assess the confidence of newly qualified health professionals working in the West Midlands in the different competencies of the NHS Leadership Framework. Most respondents felt confident in their abilities to demonstrate personal qualities and work with others, but less so at managing or improving services or setting direction.

    Alternating field and thermal demagnetization of lime- and dolostones from the Lower and Middle Ordovician (Floian to Darriwilian stages) subhorizontally bedded sequences in NW and NE Estonia reveal two characteristic magnetization components (named P and S). The intermediate-coercivity (demagnetized at 30-60 mT, up to 300-350°C) reversed polarity component P (mean of Floian Stage: Dref = 147.8 +/- 10.8°, Iref = 65.8 +/- 5.4° combined mean of Dapingian and Darriwilian stages: Dref = 166.0 +/- 8.4°, Iref = 56.1 +/- 6.5°) is regarded as the primary remanence of early diagenetic (chemical) origin. On the Baltica's apparent polar wander path (APWP), the palaeopoles (Floian: Plat = 25.0°N, Plon = 50.8°E, K = 52.7, A95 = 7.2° Dapingian and Darriwilian: Plat = 11.4°N, Plon = 39.1°E, K = 33.8, A95 = 6.7°) are placed on the Lower and Middle Ordovician segment. The poles indicate that Estonia was located at southerly latitudes, decreasing with time (Floian: ~48°S Dapingian and Darriwilian: ~37°S), when the remanence was acquired. A high-coercivity and high-unblocking-temperature component S (mean of samples: Dref = 33.7 +/- 6.3°, Iref = 51.9 +/- 5.7°) that is regarded as a secondary remanence has both normal and reversed polarities. On the European APWP, its palaeopole (Plat = 52.5°N, Plon = 157.9°E, K = 38.9, A95 = 5.3°) gives middle to late Permian age. According to mineralogical (SEM and optical microscopy) and rock magnetic (three-component induced remnant magnetization) studies, component P is carried by magnetite (coexisting with glauconite) and component S by haematite. Magnetite is of chemical origin, formed in the course of early diagenesis and/or dolomitization. During the Permian continental period haematite, the carrier of component S, was likely precipitated from oxidizing meteoric fluids in the already existing or simultaneously formed pore space between the dolomite crystals.

    Red fox (Vulpes vulpes) is the most widely distributed canid in the world and an important source of multiple zoonotic pathogens capable of causing life-threatening diseases, such as rabies and alveolar echinococcosis. Informing general public of potential risks related to foxes is becoming more important since the fox densities have increased in many countries and the species is colonizing urban areas in Europe and around the world with increasing pace, bringing zoonotic pathogens to the immediate neighbourhood of humans and their companion animals. The aim of this study was to examine the parasite fauna of red foxes in Estonia. We found in Estonian foxes a total of 17 endoparasite taxa, including ten zoonotic species. All the analysed individuals were infected and the average parasite species richness was 6·37. However, the infection rates varied to a very large extent for different parasite species, ranging from 0·9 to 91·5%. Of zoonotic species, the highest infection rate was observed for Alaria alata (90·7%), Eucoleus aerophilus (87·6%) and Uncinaria stenocephala (84·3%). The prevalence of tapeworm Echinococcus multilocularis, a causative agent for alveolar echinococcosis, was also relatively high (31·5%), presenting a potential risk to human health. PMID:27279259

  19. Occurence of Extreme Sea Level Events In The Coastal Waters of West Estonia, The Baltic Sea

    Suursaar, Ü.; Kullas, T.; Otsmann, M.; Kõuts, T.

    Extreme low and high sea level events are analysed on the basis of available historical data and mechanisms of surges studied appplying the 1 km grid step 2D hydrodynamic model in the two nearly tideless semienclosed sub-basins of the Baltic Sea, the Gulf of Riga and the Väinameri. Based on the input and verification data from 1999, the water level is modelled with realistic and idealistic forcing schemes. The low level events are associated with the local wind pattern of easterly winds, determined by the corresponding regional air pressure fields above the Central Baltic. The high levels (up to 253 cm above the long-term average as measured in Pärnu) are associated with SW and W storms. They first appear due to the water volume change in the Baltic Sea, then due to an additional volume increase in the Gulf of Riga, and finally due to the local level slope in the narrow and shallow bays. An amplification due to resonance with seiche or Helmholtz oscillation periods is also possible. Simulations showed that the extreme high and low sea levels in some small bays of West Estonia without tide- gauges could exceed the corresponding values in the Pärnu Bay.

  20. Shifts in meteorological regime of the late winter and early spring in Estonia during recent decades

    Wind, temperature and precipitation measurements at Vilsandi (the westernmost island of Estonia) and Tiirikoja (on the western coast of Lake Peipsi) collected during 1966-2005 were used to detect trends and regime shifts in monthly mean averages. A similar analysis was carried out for wind components in the free atmosphere calculated from aerological soundings. An abrupt increase in the upper-air zonal wind component around 1987 was detected in January and February over North-East Europe that may form a significant part of the intensification of the western flow. This increase is accompanied by a shift in the meteorological regime near the surface over a wider area. In March, the regime shift in the upper air flow that has taken place in the middle of the 1990s is not reflected in the meteorological parameters at the surface. Besides the regime shift at the end of the 1980s, also shifts in the middle of the 1970s and at the beginning of the 2000s are suggested.

  1. Slope stability and landslides in proglacial varved clays of western Estonia

    During the last decade the frequency of landslides at river valley slopes eroding into the glaciolacustrine plain in western Estonia has grown considerably. We studied in detail nine recent landslides out of 25 known and recorded sliding events in the area. All landslides occurred at the river banks in otherwise almost entirely flat areas of proglacial deposits capped with marine sands. Glaciolacustrine varved clay is the weakest soil type in the area and holds the largest landslides. Slope stability modelling shows that critical slope gradient for the clay is ≥ 10° and for the marine sand ≥ 20°. Fluvial erosion is the main process in decreasing slope stability at the outer bends of the river meanders. An extra shear stress generated by groundwater flow following the high stand of the groundwater level or rapid water level drawdown in the river channels are responsible for triggering the landslides. Consecutive occurrence of small-scale slides has a direct effect in triggering the large, retrogressive complexes of slides in the glaciolacustrine clay. A landslide hazard zonation map was composed based on digital elevation model and the data on spatial distribution of glaciolacustrine clays and marine sands, and on existing and critical slope angles of these deposits.

    Extraordinarily low and high sea level events are analysed on the basis of historical data and their mechanisms of occurrence are studied with the 1 km grid size 2D hydrodynamic model in the two almost tideless semi-enclosed sub-basins of the Baltic Sea, the Gulf of Riga and the Väinameri. The sea level is modelled with realistic meteorological forcing and comparison data from 1999 and 2001. Resonance properties of the sub-basins are studied and their possible role in the formation of extraordinary sea level events is discussed. While the extremely low levels (-1.23 m below the mean sea level) in the Estonian coastal waters do not generally originate locally, the high levels (up to 2.53 m above the mean as measured in the Pärnu Bay) are short-term and local. They occur in combination with several forcing and morphometrical factors and are localised in the shallow and narrow bays exposed to the direction of the strongest possible storm winds, SW and W. Model simulations show that extremely high and low sea levels in some small bays of western Estonia can exceed the corresponding values in the Pärnu Bay.

    Data obtained during 1955 1986 at the Tôravere Actinometric Station (Estonia, USSR) are used to study the long-term variations of the direct (S') and global solar radiation (Q) at the earth's surface. During these years, a certain decreasing trend was observed both in S' and in Q (ΔS'= 13%, ΔQ= 6.8%). The results from Tôravere are compared with the data on global radiation acquired in 1964 1986 at 9 different actinometric stations in northern Europe (8) and western Siberia (1). Decreasing trends have been observed in Helsinki and Stockholm (ΔQ=-11%), and also in Kaunas (ΔQ=-12%) in the same period. The variations of the cloudiness regime and atmospheric transparency as the main reasons for the decrease of radiation are discussed. According to the measurement data from Tôravere, the mean annual amount of low clouds increased by 11%, whereas the value of the Bouguer atmospheric transparency coefficient decreased by 3.7%.

  4. Cyclic sedimentation pattern in Lake Veetka, southeast Estonia: a case study

    A sediment core from Lake Veetka, southeast Estonia, 1077 cm in length and covering 10,500 calibrated years, was examined using loss-on-ignition, grain-size distribution and AMS 14C dating to reconstruct depositional dynamics. The studied core, recovered from the northern part of the lake, shows a cyclic pattern of organic and mineral matter concentration with cycle durations of 100-400 years. Cyclicity is displayed better in sediments laid down between 9,200 and 5,600 cal BP. Within two time windows (5,600-5,100 cal BP and from 1,200 cal BP to the present), sediment composition changed drastically on account of a high and fluctuating mineral matter content, obviously driven by different factors. Little Ice Age cooling is characterised by the highest proportion of mineral matter, and the Medieval Warm Period is typified by high organic matter content. The cyclic change of organic and mineral matter has been related to climate dynamics, most likely an alternation of wet and dry conditions, changes in the water level of the lake and differences in bioproduction

    Increasing human activity continues to threaten peatlands, and as the area of natural mires declines, our obligation is to restore their ecosystem functions. Several restoration strategies have been developed for restoration of extracted peatlands, including "The moss layer transfer method", which was initiated on the Tässi extracted peatland in central Estonia in May 2012. Three-year study shows that despite the fluctuating water table, rainfall events can compensate for the insufficient moisture for mosses. Total plant cover on the restoration area attained 70 %, of which ~60 % is comprised of target species-Sphagnum mosses. From restoration treatments, spreading of plant fragments had a significant positive effect on the cover of bryophyte and vascular plants. Higher water table combined with higher plant fragments spreading density and stripping of oxidised peat layer affected positively the cover of targeted Sphagnum species. The species composition in the restoration area became similar to that in the donor site in a natural bog. Based on results, it was concluded that the method approved for restoration in North America gives good results also in the restoration of extracted peatland towards re-establishment of bog vegetation under northern European conditions.

    The rocks of the crystalline basement of the East European Craton in southern Estonia show effects of partial melting under granulite facies conditions. Zircons extracted from partial melting products (tonalite from the Tapa Zone 1824 ± 26, tonalite from the South Estonian Zone 1788 ± 16 Ma and charnockite from the Tapa Zone 1761 ± 11 Ma) yield U Pb crystallisation ages that span over approximately 80 Ma, suggesting a prolonged high-grade metamorphism or several separate events. U Pb zircon age of one sample of charnockite is concordant with the Nd model age of partial melting of its host mafic granulite facies gneiss (intercept at 1.76 Ga). Linear geochemical trends and similar initial Nd isotopic compositions of mafic granulites and charnockites suggest their possible genetic relationship. From our new and previously published data it follows that the peak granulite metamorphic conditions and formation of tonalites and charnockites (850 °C and 6 kbar) in the Estonian basement occurred at 1788 1778 Ma. Then, the rocks cooled down, passing through the garnet closure temperature of approximately 650 700 °C at 1728 ± 24 Ma. The age of metamorphism of the Estonian granulites is lower than the metamorphic ages known from southern Finland, but it is similar to the age of metamorphism reported from the Belarus-Baltic Granulite Belt in Latvia.

    A total of 1640 ticks collected in different geographical parts of Estonia were screened for the presence of Rickettsia species DNA by real-time PCR. DNA of Rickettsia was detected in 83 out of 1640 questing ticks with an overall prevalence of 5.1%. The majority of the ticks infected by rickettsiae were Ixodes ricinus (74 of 83), while 9 of the 83 positive ticks were Ixodes persulcatus. For rickettsial species identification, a part of the citrate synthase gltA gene was sequenced. The majority of the positive samples were identified as Rickettsia helvetica (81 out of 83) and two of the samples were identified as Rickettsia monacensis and Candidatus R. tarasevichiae, respectively. Genetic characterization based on the partial gltA gene showed that the Estonian sequences within the R. helvetica, R. monacensis and Candidatus R. tarasevichiae species demonstrated 100% similarity with sequences deposited in GenBank, originating from Rickettsia species distributed over large territories from Europe to Asia.

    Background It is important to describe and understand the underlying patterns and dynamics that govern sex work in societies undergoing rapid political and social changes, its heterogeneity across populations, and its evolution through time in order to inform future research, sound policy formation, and programme delivery. Objectives To describe the socioeconomic and cultural determinants, organisational structure, distinct categories, and spatial patterning of sex work in Tallinn, Estonia, and identify recent temporal changes in sex work patterns. Methods In‐depth interviews with key informants; naturalistic observations of sex work and drug use venues, geo‐mapping of sex work sites, review of media, public policy, and commissioned reports, and analyses of existing data. Results Sex work takes place in a hierarchy of locations in Tallinn ranging from elite brothels and “love flats” to truck stops. These sites vary in terms of their public health importance and social organisation. There are full time, part time, and intermittent male and female sex workers. Among others, the taxi driver, madam and the bartender are central roles in the organisation of sex work in Tallinn. Cell phone and internet technology enable sex work to be highly dispersed and spatially mobile. Conclusion Future research and programmatic service delivery or outreach efforts should respond to the changing profile of sex work in Tallinn and its implications for STD/HIV epidemiology.

    Ahas, Rein

    This study analyzes a long-term phenological time series for the impact assessment of climate changes on Estonian nature and for the methodological study of the possible limitations of using phenological time series for climate trend analyses. These limiting factors can influence the results of studies more than the real impact of climate changes, which may have a much smaller numeric value. The 132-year series of the arrival of the skylark (Alauda arvensis) and the white wagtail (Motacilla alba), the 78-year series of the blossoming of the wood anemone (Anemone nemorosa), the bird cherry (Padus racemosa), apple trees (Malus domestica) and lilacs (Syringa vulgaris), and the 44-year series of the spawning of pike (Esox lucius) and bream (Abramis brama) were studied at three selected observation points in Estonia. The study of the phenological time series shows that Estonian springs have, on the basis of the database, advanced 8 days on average over the last 80-year period; the last 40-year period has warmed even faster.

    The aim of this study is to provide an overview of deaths caused by poisoning (especially illicit drugs) in Estonia from 2000 to 2009. The data on poisoning deaths (N = 4132) were collected from the autopsy reports of the Estonian Forensic Science Institute. Ethanol poisoning was the most frequent cause of death (N = 1449, 35.1%), followed by carbon monoxide (N = 1151, 27.9%) and poisoning from illicit drugs (N = 888, 21.5%). The study included 3267 male (79.1%) and 865 female fatalities, with the prevalent age group being 35-64 years. Since 2002, deaths from fentanyles have increased sharply and remained at a high level - from 63 cases in 2002 to 138 cases in 2009. This high number indicates that in spite of the state's drug policies, illegal drugs remain easily available and that this area requires more attention. Alcohol abuse prevention policies - restrictions on alcohol advertisements in the media, limitations on sale times and anti-alcohol campaigns concerning traffic - have not brought about a significant decrease in ethanol poisoning.

    Due to changes in gambling accessibility during the last decade gambling has become more widespread in Estonia and the prevalence of pathological gambling has sharply increased. The present study attempts to identify psychological characteristics of Estonian pathological gamblers. It has been shown that a wide range of social, economic, and individual factors (e.g. personality traits and emotional states) predict the likelihood of becoming a pathological gambler. In the present study, pathological gamblers' (N = 33) personality traits, self-esteem, self-reported emotional states and cognitive ability were compared to the respective characteristics in a non-gambling control group (N = 42) matched for age, gender and educational level. It was found that compared to controls, pathological gamblers had higher scores on Neuroticism (especially on its immoderation facet) and lower scores on Conscientiousness (especially on its dutifulness and cautiousness facets) and on self-esteem scale. They reported more negative emotional states during the previous month (especially depression and anxiety). Finally, pathological gamblers had lower general cognitive ability. In a logistic regression model, the likelihood of being a pathological gambler was best predicted by high immoderation score and low cognitive ability.

  13. Neugrund structure — the newly discovered submarine early Cambrian impact crater

    Suuroja, Kalle; Suuroja, Sten

    The Neugrund Bank is situated on the southern side of the entrance of the Gulf of Finland (59°20N; 23°31E) between Osmussaar and Krass islands. It is a shoal of a very peculiar multi-ring shape. In the coastal and offshore area of North-Western Estonia, numerous erratic boulders, consisting of rocks resembling impact breccias, have been found. The investigations proved that under Neugrund Bank and in its surrounding is located a classic buried and partially newly exposed impact crater. The studies revealed the general morphology of the structure. In the summer of 1998, during three expeditions, the submarine impact structure was investigated in detail by diving and sidescan sonar profiling. As a result, the hypothesis, which had been indirectly indicated by remote sensing, was finally verified. The Neugrund impact crater formed ca. 540 My ago in a shallow epicontinental sea as the result of the impact of an extraterrestrial body with a diameter of ca. 400 m. As a consequence of the impact a crater with the rim-to-rim diameter of 7 km was formed. The depth of the ca. 5 km-diameter crater has not yet been determined, but is assumed to range over 500 m. At the distance of about 10 km around the crater, the target rocks are strongly disturbed. After the impact the crater deep was filled with clastic deposits and was buried within a rather short time (some millions of years). The sedimentation conditions in the crater differed from those of the surrounding area until the Middle Ordovician. Since then, and up to the Tertiary, the crater remained buried and was partially uncovered during the Neogene.

  14. Survival of newly postmitotic motoneurons is transiently independent of exogenous trophic support.

    We compared the survival requirements of early- and late-born motoneurons from E5 chicken spinal cord. Density gradient centrifugation followed by immunopanning using SC1 antibody allowed us to purify two size classes of motoneuron. Large motoneurons retained by 6.8% metrizamide were shown by BrdU labeling in ovo to be born on average 1.5 d earlier than the small motoneurons recovered from the metrizamide pellet. Large motoneurons were both biochemically and functionally more mature: they expressed higher levels of choline acetyltransferase and low-affinity neurotrophin receptor, and had an acute requirement for trophic support from muscle-derived factors. After 24 hr in culture in basal medium, all early-born motoneurons died, whereas 60% of late-born motoneurons survived. Small motoneurons can develop into large motoneurons in ovo, suggesting that they represent a general transitional stage in motoneuron development. Our results suggest that a defined period elapses between birth of a motoneuron and its acquisition of trophic dependence, possibly corresponding to the time required for target innervation. This property may have important consequences for the timing and regulation of developmental motoneuron death.

    A surge of progress in magnetospheric substorm studies is expected by the following three recent developments: (1) the finding of the solar wind-magnetosphere energy coupling function epsilon, (2) the determination of the Pedersen current distribution over the entire polar region, and (3) a new understanding of the auroral potential structure. In this paper, the significance of the three developments and the newly emerging model of magnetospheric substorms is described.

    This paper presents a new approach for incorporating public hospitals by contrasting the experience from an "old" EU country (Austria) with a new EU member state (Estonia). In the EU (including the new member states) hospital overcapacity is a serious problem, from a technical, fiscal and political perspective. Few countries have succeeded in establishing an appropriate framework for resource management and for guaranteeing long-term financial viability of their hospital network. Many countries are in search of effective policies for improved hospital management and more cost-effective resource use in the health sector. Over the past decade, experiences in Austria and Estonia have emerged as innovative examples which may provide lessons for other EU countries and beyond. This paper describes the evolution of public hospitals from public budgetary units and public management to incorporated autonomous organizations under private corporate law, resulting in a contractual relationship between (public) owners and private hospital management. Outdated and inefficient public sector structures were replaced by more agile corporate management. The arrangement allows for investments, operating costs and budgeting according to strategic business goals as opposed to political "fiat". Shielding hospitals from local political influence is an important aspect of this concept. Horizontal integration through networking of public hospitals and introducing private management helps create a new corporate culture, allowing for more flexibility to achieve efficiencies through downsizing and economies of scale. Based on contracts the new balance between ownership and managerial functions create strong incentives for a more business-like, results-oriented and consumer-friendly management. This was achieved both in Austria and Estonia in a politically sensitive way, adopting a long-term vision and by protecting the interests of hospital owners and staff. PMID:16919838

    The raccoon dog (Nyctereutes procyonoides) is an alien species in Europe and an important vector of zoonotic diseases. However, compared to the red fox (Vulpes vulpes), less attention has been paid to the raccoon dog as a potentially important host for Echinococcus multilocularis, the infective agent of alveolar echinococcosis, which is an emerging infectious disease with a high mortality rate. We examined the small intestines of 249 Estonian raccoon dogs and found 1.6% of individuals to be infected with E. multilocularis. The relatively large difference between this prevalence and that found in sympatric red foxes (31.5%) sampled during the same time period might be due to differences in diet: red foxes consume significantly more arvicolid rodents - the main intermediate hosts of the parasite - especially during the coldest period of the year when raccoon dogs hibernate. Nonetheless, given the relatively high density of raccoon dogs, our results suggest that the species also represents an important definitive host species for E. multilocularis in Estonia. Compared with other countries in Europe where E. multilocularis-infected raccoon dogs have been recorded (Latvia, Lithuania, Poland, Germany, and Slovakia), the prevalence in Estonia is low. The longer hibernation period of raccoon dogs at higher latitudes may explain this pattern. Both mitochondrial and nuclear loci were analysed for Estonian isolates: based on EmsB microsatellite genotyping the Estonian isolates shared an identical genotype with E. multilocularis in northern Poland, suggesting a common history with this region. The data from more than a quarter of the mitochondrial genome (3558 bp) revealed two novel haplotypes specific to Estonia and placed them into the same haplogroup with isolates from other European regions. Considering that the raccoon dog is becoming increasingly widespread and is already relatively abundant in several countries in Europe, the role of the species must be taken into

    Fire is the primary process which organizes the physical and biological attributes of the boreal biome and influences energy flows and biogeochemical cycles, particularly the carbon (C) cycle. Especially the soil organic matter pool in boreal forests is an important C storage with a long C turnover time, but fire frequencies that are expected to increase with changing climate, can change that. We compared the initial recovery of C pools and CO2 efflux following fire disturbances in Scots pine (Pinus sylvesteris L.) stands with different time since fire. The study areas are located in hemiboreal vegetation zone, in northwestern Estonia, in Vihterpalu. Six areas (with extensive fires 200 ha and more) were chosen for study: fire in a year 1837, 1940, 1951, 1982, 1997, and 2008. In all areas we are dealing with stand replacing fires where all (or almost all) of the stand was destroyed by fire. On every area we established three permanent sample plots. Soil respiration was measured manually from all sample plots (measuring interval of two - three weeks). Manual chamber measurements are performed on 5 collars (north - south orientated and the distance between collars is 5 m) at each sample plot from May till November 2015. To characterize the soil C and N content and fine root biomass at the sites, 5 soil cores (0.5 m long and 0.05 m in diameter) were taken from each sample plot. Our results show that forest fire has a substantial effect on the C content in the top soil layer, but not in the humus layer and in mineral soil layers. Soil respiration showed similar chronological response to the time since the forest fire indicating that substantial proportion of the respiration was originating from the very top of the soil. Soil respiration values were lowest on the area where the fire was in a year 2008 and the respiration values followed also seasonal pattern being highest in August and lowest in May and November. The CO2 effluxes were lowest on newly burned area through

    Varved clays are commonly found glaciolacustrine sediments representing high-resolution environmental archives of the deglaciation events. We examine varve formation in the Baltic Ice Lake at the Pärnu Bay area, Estonia, during the deglaciation of the last Scandinavian glaciation from the region. The data set of Hang and Kohv (2013) spanning 584 years is used. Analysis of the spatial variation of the seasonal layer thickness distribution based on 26 sediment cores and sub-varve resolution grain size analysis from a single section was performed. The Baltic Ice Lake water level reconstruction indicates that the water depth at the study region was up to 80 m (Rosentau et al., 2009). It is found that during the first ~130 years after the ice retreat the summer sedimentation was dominated by sediment loaded underflows emanating form the ice margin: summer layer thickness is strongly positively correlated with water depth. The winter layer thickness during this period does not demonstrate significant correlation with water depth suggesting that the simple raining-out of the suspended material from a water column was complicated by water circulation. Ice retreat from the Pandivere-Neva line of the marginal formations just north from study area took place during the interval from 96 to 130 local varve years. During the transition marked shift from proglacial to distal sedimentary environment is observed: the summer layer thickens decreased dramatically and it's thickens is markedly higher in the area close to the ice margin. The winter layer thickens becomes strongly correlated to the water depth, suggesting that the simple sedimentation model with no water circulation and addition of no new sediments is valid. The grain size data is used to estimate the "terminal grain size" - the size of the larges particles sedimented at the top of the winter layer. Provided that no significant water circulation took place during the winter, the terminal grain size will be controlled

  2. Eutrophication History of Small Shallow Lakes in Estonia: Evidence from Multiproxy Analysis of Lake Sediments

    Human activities have impacted aquatic systems through the release of contaminants and the regulation of surface and groundwater. Although environmental monitoring has been essential in detecting eutrophication, biodiversity loss or water quality deterioration, monitoring activities are limited in time and are thus not sufficient in their scope to identify causality and thresholds. Paleolimnological studies increasingly show that the response of lakes to climatic and human influences is complex, multidimensional, and often indirectly mediated through watershed processes. In this study we examine the history of eutrophication processes in small lakes in Estonia using the multi-proxy analysis of sediment. Study sites represent lakes with different anthropogenic stressors: urbanisation and recreational use, run-off from an oil shale mine, and fish-kills and liming measures. We have used diverse analytical methods, such as elemental analysis, stable isotopes, fossil pigments, diatoms and Cladocera remains. The information derived from sedimentary indicators broadly agrees with the historical evidence of eutrophication and pollution. Moreover, the sediment records are indispensable for identifying additional issues such as: 1) earlier onset of cultural eutrophication; 2) the significant impact of catchment erosion on the deterioration of lake quality, particularly cyanobacterial blooms; and 3) changes in sedimentation processes with significance for internal biogeochemical cycling of nutrients. Importantly, the integration of several methods has significantly improved interpretation of sedimentary data and elucidated the different strengths of various indicator types. The project findings prove to be highly relevant for both the prediction of the ecological responses of lakes to different anthropogenic impacts and the establishment of reasonable reference target conditions in restoration schemes, as well as for methodological improvements of the sediment analysis.

    Despite of different estimation techniques for integrated column water vapour (precipitable water, PW, W), no method is identified as the most accurate or reference method. In this work we report intercomparisons, by assessing the reliability, linear fits, correlations and biases, between four W estimation methods - radiosonde, AERONET, GPS and HIRLAM. Two intensive observational periods at Tõravere, Estonia, were used: (1) 9-12 August 2010, and (2) 22 June - 7 November 2008. For the first, short campaign, data obtained with all four methods were available. During the campaign, 17 GRAW DFM-06 (Germany) sondes were launched. Average differences between W , from radiosonde, as a traditional instrument, and other three methods were smaller than 5%. HIRLAM produced the lowest W estimates of the four methods. Considering the second, longer campaign, only observations by GPS, AERONET and HIRLAM were conducted (GPS-registered W ranged from 4.3 to 42.8 mm). By analyzing more than 1000 concurrent observations, a good agreement among all three methods was established: W (GPS) was 1% higher than W (HIRLAM) and 3% higher than W (AERONET), W (HIRLAM) was 2% higher than W (AERONET). The comparison indicates that correlations between different techniques were high, with coefficient of determination (R2) above 0.86 in all cases. However, compared to HIRLAM and GPS, AERONET overestimated W by 5-9% at W < 12 mm and underestimated by 6-10% at W > 25 mm. Relatively low temporal and spatial resolution of the HIRLAM grid caused higher scatter from other methods. The study suggests that besides radiosonde, as a traditional meteorological tool, the most reliable W estimation is by GPS.

    Aleutian mink disease virus (AMDV) causes a severe disease called Aleutian disease (AD). AMDV infects primarily mustelids, but also other mammal species. Recent evidence suggests that AMDV may also affect humans. To examine AMDV in different wild animals and in farmed mink in Estonia, we collected 203 blood samples from eight mammal species in 2007-2010, of which 152 were from species living in the wild (American mink, European mink, pine marten, polecat, raccoon dog, badger, otter, and stone marten) and 51 were from farmed mink. AMDV was tested by PCR amplification of NS1 and VP2 gene fragments, and was only detected in 4 free-ranging (14.8%) and 11 farmed (21.6%) American mink. No other species was positive for AMDV. In addition, the VP2 gene fragment was sequenced for 14 farmed mink isolates from Finland for which NS1 sequences were already publicly available. None of the four Estonian AMDV isolates found in free-ranging mink had identical sequences with farmed mink. In fact, isolates from free-ranging and farmed mink belonged to different clades, suggesting that the analyzed virus isolates circulating in nature are not from escapees of current farms. Two global phylogenies were built: one based on NS1 (336 bp, 151 taxa from nine countries); the other based on a combined NS1-VP2 dataset (871 bp, 40 taxa from six countries). AMDV genotypes did not cluster according to their geographic origin, suggesting that transport of farm mink from multiple source farms has been intense. Nevertheless, one subclade in both phylogenies was comprised solely of isolates from farmed mink, while several subclades comprised isolates only from free-ranging mink, indicating that some isolates may circulate more in the wild and others among farm animals.

    The aims of the current survey were to evaluate factors influencing purchase of prescription and OTC medicines of pharmacy customers in Tallinn, Estonia and to identify the role of community pharmacists in counselling of prescription and OTC medicines. Structured questionnaire was used to interview pharmacy customers (n = 1820) in six community pharmacies of Tallinn, the capital city of Estonia. The survey instrument consisted of 15 multiple-choice items. According to the survey results, prescription and OTC medicines were bought from community pharmacies almost equally. The most popular OTC medicines were analgesics (38%), cold and cough medicines (21%). The older survey participants and these with lower income and with elementary school education bought more prescription medicines (p < 0.01). Survey participants with higher income were purchasing more OTC medicines and food supplements (p < 0.01). Before purchase of medicines recommendations were received mainly from physicians about prescription and from pharmacists about OTC medicines. However, the counselling provided by community pharmacists in selecting of both types of medicines was highly appreciated. Pharmacists as source for drug information were less trusted among the survey participants < 25 and 26-40 years (p < 0.01). Fast service and confidential counselling about medicines was less important for the respondents with elementary school education (p < 0.01).

    Trichinella spp. are relevant zoonotic pathogens in Estonia. The aim of this nationwide cross-sectional study was to estimate the seroprevalence of Trichinella spp. in domestic pigs (Sus scrofa domestica) and hunted wild boars (Sus scrofa). Serum samples from 374 pigs, originating from 14 farms, and meat juice samples from 470 wild boars were tested for immunoglobulin G antibodies against Trichinella excretory/secretory antigens using a commercial enzyme-linked immunosorbent assay (ELISA). Antibodies against Trichinella were not detected in the domestic pigs, indicating effective parasite control strategies in the farms. By contrast, 42.1% of the wild boars tested positive, indicating substantial infection pressure in the sylvatic cycle. Further analysis of a subset of the wild boar samples, using another ELISA and Western blot, yielded a confirmed seroprevalence estimate of 17.4%. A substantial proportion of wild boars in Estonia had evidence of exposure to Trichinella spp. and may have carried infective larvae. Undercooked Estonian wild boar meat is a potential source of Trichinella spp. infections to humans and other hosts. PMID:27315523

    We have extended our PNe survey to the outer ~64deg^2 of the LMC using maps from the Magellanic Cloud Emission Line Survey (MCELS) and the UKST H-alpha and red surveys. Although the MCELS survey has poorer ~5 arcsecond resolution than the UKST survey, it has the advantage of additional narrow-band filters at H-alpha, [OIII] and [SII], providing improved diagnostic capabilities. The UKST survey has a similar angular resolution (~2 arcsec from 0.67 arcsec pixels) to our original median stacked map of the central 25deg^2 of the central LMC, but lacks the depth advantages provided by median stacking. Using these data to uncover new emission line candidates we have so far spectroscopically confirmed an extra 63 LMC PNe which we present here. We have also independently recovered and spectroscopically confirmed 107 of the 109 (98%) PNe that were previously known to exist in the outer LMC. The majority of our newly discovered and previously known PNe were confirmed using the AAOmega, multi-object fibre spectroscopy system on the 3.9-m Anglo-Australian Telescope (AAT) and the 6dF multi-object spectrograph on the UK Schmidt Telescope (UKST). These newly identified PNe were cross-checked using extant multi-wavelength imaging surveys in the near and mid-infrared in particular and against the latest emission-line ratio diagnostic plots for improved confidence in PNe identification. These new identifications raise the number of known PNe in the LMC to 715, approaching the number of 900 predicted by stellar evolutionary theory. We present accurate positions, diagnostic plots based on de-reddened emission lines, multi-wavelength SEDs and mid-infrared plots based on SAGE spitzer data.

    Next-generation sequencing (NGS) technologies have made high-throughput sequencing available to medium- and small-size laboratories, culminating in a tidal wave of genomic information. The quantity of sequenced bacterial genomes has not only brought excitement to the field of genomics but also heightened expectations that NGS would boost antibacterial discovery and vaccine development. Although many possible drug and vaccine targets have been discovered, the success rate of genome-based analysis has remained below expectations. Furthermore, NGS has had consequences for genome quality, resulting in an exponential increase in draft (partial data) genome deposits in public databases. If no further interests are expressed for a particular bacterial genome, it is more likely that the sequencing of its genome will be limited to a draft stage, and the painstaking tasks of completing the sequencing of its genome and annotation will not be undertaken. It is important to know what is lost when we settle for a draft genome and to determine the “scientific value” of a newly sequenced genome. This review addresses the expected impact of newly sequenced genomes on antibacterial discovery and vaccinology. Also, it discusses the factors that could be leading to the increase in the number of draft deposits and the consequent loss of relevant biological information. PMID:24921006

    A management project was carried out to reduce the stress among newly hired nursing professionals in our hospital. A work group was set up which, utilizing interviews and consensus seeking techniques, identified the main stress causing factors from which a Welcoming Program was designed having two fundamental aspects: on the one hand, a welcoming program which serves to create an atmosphere of trust in order to aid a new professional's integration; while on the other hand, providing the newcomer with a welcoming guide which includes the most pertinent information regarding the Nursing Department, the Health Center and the Health District. This program was applied to 431 newly hired professionals between the years 1996 and 1999. In order to evaluate the results, a questionnaire sent to those newcomers hired over the past year, obtaining 91 sample cases. 96.7% considered the information regarding the Center's norms to be "very useful"; 94.5% considered the information regarding Center's structure to be "very useful"; and 57.1% considered the information regarding the Health District to be "very useful". 96.7% considered it "very favorable" to know the Nursing management team and the entire group found this Program very satisfactory and feel integrated in this Hospital. Compared to the four previous years before the implementation of this program, labor absences inferior to 48 hours were reduced by 28% and global absenteeism declined 8%.

    Two eddy towers, one in the mixed Norway spruce - Silver birch forest in Liispõllu (58°16'N 27°16'E tower height 20 m) and another one in Scots pine forest in Soontaga (58°01'N 26°04'E; 36 m) both located in southern Estonia - were equipped with CO2/H2O analyzer for mixing ratio of CO2 (Licor 7200 Li-Cor Inc, Lincoln, NE, USA) and 3-D ultrasonic anemometer for wind measurements (Gill Windmaster Pro; Solent, Lymington, UK) and used for measurement of carbon dioxide balance and net ecosystem exchange (NEE). In Liispõllu, the studies were conducted in Auguat and September 2011 above the forest canopies and at 1.5 m above the soil surface.. In Soontaga, measurements lasted from April to October 2012. The data acquisition system consists of the LI-7550 Analyzer Interface Unit, 3G wireless router and analog-to-digital converter that were used to record turbulence and scalar signals. Signals from the sensor and anemometer were recorded 20 times sec-1. The eddy fluxes were averaged over 30 minute time intervals. The flux calculations and corrections of were done using EddyPro program. In addition, soil respiration was measured with automatic chambers in Liispõllu and with closed chambers in Soontaga twice a month from April to October 2011 and 2012. In both study areas around the towers, soil physical and chemical parameters in 3 depths, biomass of trees and understory species, C sequestration in biomass and litter decay has been measured. In Soontaga pine forest the average monthly CO2 flux varied from -59.2 to -388.8 mg m-2 h-1 showing a regular seasonal temperature-related variation. CO2 flux from lowered in spring and summer as plants consume the gas through photosynthesis and days are longer, and rise during the autumn and winter as plants go dormant, die and decay and when also the daytime is shorter. The average monthly flux over the analyzed period was -246.5 mg m-2 h-1. In consequence, the CO2 sequestration from the atmosphere was highest in June. In Liisp

    The authors provide a transcription, translation, and evaluation of nine newly discovered letters from the alchemist Michael Maier (1568-1622) to Gebhardt Johann von Alvensleben (1576-1631), a noble landholder in the vicinity of Magdeburg. Stemming from the final year of his life, this correspondence casts new light on Maier's biography, detailing his efforts to secure patronage amid the financial crisis of the early Thirty Years' War. While his ill-fated quest to perfect potable gold continued to form the central focus of his patronage suits, Maier also offered his services in several arts that he had condemned in his printed works, namely astrology and "supernatural" magic. Remarks concerning his previously unknown acquaintance with Heinrich Khunrath call for a re-evaluation of Maier's negotiation of the discursive boundaries between Lutheran orthodoxy and Paracelsianism. The letters also reveal Maier's substantial contribution to a work previously ascribed solely to the English alchemist Francis Anthony. PMID:25241502

    The authors provide a transcription, translation, and evaluation of nine newly discovered letters from the alchemist Michael Maier (1568-1622) to Gebhardt Johann von Alvensleben (1576-1631), a noble landholder in the vicinity of Magdeburg. Stemming from the final year of his life, this correspondence casts new light on Maier's biography, detailing his efforts to secure patronage amid the financial crisis of the early Thirty Years' War. While his ill-fated quest to perfect potable gold continued to form the central focus of his patronage suits, Maier also offered his services in several arts that he had condemned in his printed works, namely astrology and "supernatural" magic. Remarks concerning his previously unknown acquaintance with Heinrich Khunrath call for a re-evaluation of Maier's negotiation of the discursive boundaries between Lutheran orthodoxy and Paracelsianism. The letters also reveal Maier's substantial contribution to a work previously ascribed solely to the English alchemist Francis Anthony.

    Reanalyses on global to regional scales are widely used for validation of meteorological or hydrological models and for many climate applications. However, the evaluation of the reanalyses itself is still a crucial task. A major challenge is the lack of independent observations, since most of the available observational data is already included, e. g. by the data assimilation scheme. Here, we focus on the evaluation of dynamical reanalyses which are obtained by using numerical weather prediction models with a fixed data assimilation scheme. Precipitation is generally not assimilated in dynamical reanalyses (except for e.g. latent heat nudging) and thereby provides valuable data for the evaluation of reanalysis. Since precipitation results from the complex dynamical and microphysical atmospheric processes, an accurate representation of precipitation is often used as an indicator for a good model performance. Here, we use independent observations of daily precipitation accumulations from European rain gauges (E-OBS) of the years 2008 and 2009 for the intercomparison of various regional reanalyses products for the European CORDEX domain (Hirlam reanalysis at 0.2°, Metoffice UM reanalysis at 0.11°, COSMO reanalysis at 0.055°). This allows for assessing the benefits of increased horizontal resolution compared to global reanalyses. Furthermore, the effect of latent heat nudging (assimilation of radar-derived rain rates) is investigated using an experimental setup of the COSMO reanalysis with 6km and 2km resolution for summer 2011. Further, we present an observation independent evaluation based on kinetic energy spectra. Such spectra should follow a k-3 dependence of the wave number k for the larger scale, and a k-5/3 dependence on the mesoscale. We compare the spectra of the aforementioned regional reanalyses in order to investigate the general capability of the reanalyses to resolve events on the mesoscale (e.g. effective resolution).

    The Cameras for Allsky Meteor Surveillance (CAMS) video-based meteoroid orbit survey adds 60 newly identified showers to the IAU Working List of Meteor Showers (numbers 427, 445-446, 506-507, and part of 643-750). 28 of these are also detected in the independent SonotaCo survey. In total, 230 meteor showers and shower components are identified in CAMS data, 177 of which are detected in at least two independent surveys. From the power-law size frequency distribution of detected showers, we extrapolate that 36% of all CAMS-observed meteors originated from ∼700 showers above the N = 1 per 110,000 shower limit. 71% of mass falling to Earth from streams arrives on Jupiter-family type orbits. The transient Geminids account for another 15%. All meteoroids not assigned to streams form a sporadic background with highest detected numbers from the apex source, but with 98% of mass falling in from the antihelion source. Even at large ∼7-mm sizes, a Poynting-Robertson drag evolved population is detected, which implies that the Grün et al. collisional lifetimes at these sizes are underestimated by about a factor of 10. While these large grains survive collisions, many fade on a 104-y timescale, possibly because they disintegrate into smaller particles by processes other than collisions, leaving a more resilient population to evolve. The meteors assigned to the various showers are identified in the CAMS Meteoroid Orbit Database 2.0 submitted to the IAU Meteor Data Center, and can be accessed also at

    Obstructive sleep apnea (OSA) is associated with high cardiovascular morbidity and mortality. Recent studies have shown that it is associated with atherosclerosis and left ventricular dysfunction markers. The aim of this study was to assess the cardiovascular effects of OSA depending on its severity, in patients without clinically diagnosed cardiovascular disease. One hundred thirty newly diagnosed, nondiabetic OSA patients (mean age 49 ± 10 years), without vasoactive treatment were included. They underwent clinical and ambulatory blood pressure measurements, echocardiography, carotid ultrasound examination, and a carotid–femoral pulse wave velocity (PWV) measurement. Seventy-five percent of the subjects were hypertensive according to the clinical or ambulatory measurement. More patients with the most severe forms (respiratory disturbance index >37/hour) had a nondipper profile (52% vs 34%; P = 0.025) and their left ventricular mass was higher (40 ± 7 vs 36 ± 8 g/m, p = 0.014). This last parameter was independently and inversely associated with mean nocturnal oxygen saturation (P = 0.004). PWV and carotid intima-media thickness did not differ between one OSA severity group to another, but the prevalence of carotid hypertrophy was higher when mean SaO2 was below 93.5% (29.5 vs 16%; P = 0.05). Our study shows that in OSA patients without clinically diagnosed cardiovascular disease, there is a significant left ventricular and arterial effect, which is even more marked when OSA is severe.

    In this study the performance of two newly developed personal bioaerosol samplers was evaluated. The two test samplers are cyclone-based personal samplers that incorporate a recirculating liquid film. The performance evaluations focused on the physical efficiencies that a personal bioaerosol sampler could provide, including aspiration, collection, and capture efficiencies. The evaluation tests were carried out in a wind tunnel, and the test personal samplers were mounted on the chest of a full-size manikin placed in the test chamber of the wind tunnel. Monodisperse fluorescent aerosols ranging from 0.5 to 20 microm were used to challenge the samplers. Two wind speeds of 0.5 and 2.0 m/sec were employed as the test wind speeds in this study. The test results indicated that the aspiration efficiency of the two test samplers closely agreed with the ACGIH inhalable convention within the size range of the test aerosols. The aspiration efficiency was found to be independent of the sampling orientation. The collection efficiency acquired from these two samplers showed that the 50% cutoff diameters were both around 0.6 microm. However the wall loss of these two test samplers increased as the aerosol size increased, and the wall loss of PAS-4 was considerably higher than that of PAS-5, especially in the aerosol size larger than 5 microm, which resulted in PAS-4 having a relatively lower capture efficiency than PAS-5. Overall, the PAS-5 is considered a better personal bioaerosol sampler than the PAS-4.

    The estimates of the age of the Kaali impact structure (Saaremaa Island, Estonia) provided by different authors vary by as much as 6000 years, ranging from ~6400 to ~400 before current era (BCE). In this study, a new age is obtained based on 14C dating charred plant material within the proximal ejecta blanket, which makes it directly related to the impact structure, and not susceptible to potential reservoir effects. Our results show that the Kaali crater was most probably formed shortly after 1530-1450 BCE (3237 ± 10 14C yr BP). Saaremaa was already inhabited when the bolide hit the Earth, thus, the crater-forming event was probably witnessed by humans. There is, however, no evidence that this event caused significant change in the material culture (e.g., known archeological artifacts) or patterns of human habitation on Saaremaa.

    Evidence from a number of historical studies has demonstrated a strong impact of the provision of clean water on mortality risks, while no clear effect has been reported in others. We investigated the relationship between water supply, sanitation, and infant survival in Tartu, a university town in Estonia, 1897-1900. Based on data from parish registers, which were linked to the first census of the Russian Empire, the analysis reveals a clear disadvantage for infants in households using surface water, compared with families that acquired water from groundwater or artesian wells. The impact is stronger in the later stages of infancy. Competing-risk analysis shows that the effect is more pronounced for deaths caused by diseases of the digestive system. Our findings suggest that it may have been possible to improve the water supply, and consequently reduce infant mortality, before the introduction of piped water and sewage systems. PMID:27207615

    Despite the high number of injecting drug users (IDUs) in Estonia, little is known about involving pharmacies into human immunodeficiency virus (HIV) prevention activities and potential barriers. Similarly, in other Eastern European countries, there is a need for additional sources for clean syringes besides syringe exchange programmes (SEPs), but data on current practices relating to pharmacists' role in harm reduction strategies is scant. Involving pharmacies is especially important for several reasons: they have extended hours of operation and convenient locations compared to SEPs, may provide access for IDUs who have avoided SEPs, and are a trusted health resource in the community. We conducted a series of focus groups with pharmacists and IDUs in Tallinn, Estonia, to explore their attitudes toward the role of pharmacists in HIV prevention activities for IDUs. Many, but not all, pharmacists reported a readiness to sell syringes to IDUs to help prevent HIV transmission. However, negative attitudes toward IDUs in general and syringe sales to them specifically were identified as important factors restricting such sales. The idea of free distribution of clean syringes or other injecting equipment and disposal of used syringes in pharmacies elicited strong resistance. IDUs stated that pharmacies were convenient for acquiring syringes due to their extended opening hours and local distribution. IDUs were positive toward pharmacies, although they were aware of stigma from pharmacists and other customers. They also emphasized the need for distilled water and other injection paraphernalia. In conclusion, there are no formal or legislative obstacles for providing HIV prevention services for IDUs at pharmacies. Addressing negative attitudes through educational courses and involving pharmacists willing to be public health educators in high drug use areas would improve access for HIV prevention services for IDUs.

  8. The marine Eemian of the Baltic: new pollen and diatom data from Peski, Russia, and Põhja-Uhtju, Estonia

    Several relatively well-preserved last interglacial (Eemian, marine oxygen isotope substage 5e; ca. 130-116 ka) deposits containing marine diatom flora have been found in Finland. In addition to these Finnish sites, more numerous Eemian (Mikulino) marine deposits are known from the northwestern part of Russia and from Estonia.Two new clayey and silty deposits covered by till, one at Peski, Russia, and the other Põhja-Uhtju, Estonia, were studied for pollen and diatom content. At Peski, the deposit representing the Eemian interglacial is 3.8 m thick. The polyhalobous diatom flora in the Corylus and Carpinus zones indicates the maximum of the marine transgression during the climatic optimum. Later, the increasing proportion of brackish water diatom flora indicates a lowering in the relative sea-level, and finally, during a very late phase of the Eemian, the sharply increasing proportion of freshwater species indicates the isolation of the sedimentary basin from the Eemian Sea.At Põhja-Uhtju, according to the pollen, the Eemian deposit is 3.5 m thick. Diatoms occur only in a layer 1.6 m thick, which represents the period of Corylus and Carpinus zones, and thus the period of the climatic optimum. The brackish-marine diatom flora consists mainly of littoral, shallow-water species.Although Peski is situated at a higher altitude than Põhja-Uhtju at present, the diatom stratigraphy at Peski indicates deeper and more saline conditions than at Põhja-Uhtju during the Eemian. This probably is the result of variations in glacio-isostatic rebound between these sites, which can be accounted for by differences of the ice load during the final phase of the Saalian glaciation.

    Background Even though respiratory symptoms are common in the adult population, there is limited research describing their impact on everyday life and association with health care consumption. Aim The main objective of this population-based study was to estimate and compare the prevalence of respiratory symptoms among adults in Finland, Estonia, and Sweden in relation to health care consumption and to identify factors influencing health care consumption. A secondary aim was to assess to which extent the presence of respiratory symptoms affect everyday life. Method In the population-based FinEsS studies consisting of random samples of subjects aged 20 to 69 years from Finland (n=1,337), Estonia (n=1,346), and Sweden (n=1,953), data on demographics, respiratory health, and health care consumption were collected by structured interviews. Prevalence was compared and multiple logistic regression analyses were performed. Results Respiratory symptoms were significantly more common in Finland (66.0%) and Estonia (65.2%) than in Sweden (54.1%). Among subjects with respiratory symptoms, the proportion reporting outpatient care during the past year was fairly similar in the three countries, while specialist consultations were more common in Finland (19.1%), and hospitalisations more common in Estonia (15.0%). Finnish and Estonian residency, female sex, and BMI>25 increased the risk for outpatient care consumption. Wheeze and attacks of shortness of breath in the past 12 months, recurrent sputum production, and cough were associated with an increased risk for health care consumption. Increasing number of respiratory symptoms increased the risk for consuming health care. A larger proportion of subjects in Estonia and Sweden experienced their everyday life being affected by respiratory symptoms compared with subjects in Finland. Conclusion Respiratory symptoms are common in Finland, Estonia, and Sweden and contribute to a negative impact on everyday life as well as increased

    The Kaali impact field consists of nine identified craters located on the Saaremaa Island in Estonia. The largest crater is 110 m in diameter (centered around 58°22'21.94"N, 22°40'09.91" E). It was formed by impact of an IAB iron meteoroid into Silurian dolomite target rocks covered by up to a few meters of glacial till (Veski et al. 2007). The age of the Kaali impact structure is still a matter of debate, and the estimates provided by different authors vary considerably between ~6400 BC (Raukas et al. 1995, Moora et al. 2012) and ~400 BC (Rasmussen et al. 2000, Veski et al. 2001). These ages were derived by 14C dating of marker horizons, characterized by a slightly elevated iridium content within the nearby Piila bog yielding a calibrated age of 800-400 BC (Rasmussen et al. 2000, Veski et al. 2001) and occurrences of glassy siliceous material in the Piila bog (~6400 BC: Raukas et al. 1995) or iron microspherules in an organic-rich layer of the Reo gravel pit (6400 BC: Moora et al. 2012). However, the source of the foreign material within those layers was never unequivocally connected with the Kaali crater. 14C dating of material from post-impact organic sediments within Kaali impact craters yielded ages between 1800-1500 BC (Saarse et al. 1991, Veski et al. 2004) and 1450-400 BC (Aaloe et al. 1963). These dates underestimate the age of impact as organic sediments within the crater started to form at unknown period after the impact. On the other hand, Veski et al. (2004) suggested a reservoir effect that might have caused artificially "aging" of the organic matter because the crater was emplaced within Silurian dolomite which is rich in old carbon. The aim of this study is to determine the age of the Kaali crater by 14C dating of organic material covered by the continuous layer of proximal ejecta. This research was conducted in conjunction with a new structural investigation of Kaali Main (Zanetti et al. 2015). Ten samples collected from different locations

    In the present paper, inorganic arsenic species and chemical parameters in groundwater were determined to investigate the factors related to the distribution of arsenic species and their dissolution from rock into groundwater. For the study, groundwater and core samples were taken at different depths of two newly drilled wells in Huron and Lapeer Counties, Michigan. Results show that total arsenic concentrations in the core samples varied, ranging from 0.8 to 70.7 mg/kg. Iron concentration in rock was about 1800 times higher than that of arsenic, and there was no correlation between arsenic and iron occurrences in the rock samples. Arsenic concentrations in groundwater ranged from <1 to 171 ??g/l. The arsenic concentration in groundwater depended on the amount of arsenic in aquifer rocks, and as well decreased with increasing depth. Over 90% of arsenic existed in the form of As(III), implying that the groundwater systems were in the reduced condition. The results such as high ferrous ion, low redox potential and low dissolved oxygen supported the observed arsenic species distribution. There was no noticeable difference in the total arsenic concentration and arsenic species ratio between unfiltered and filtered (0.45 ??m) waters, indicating that the particulate form of arsenic was negligible in the groundwater samples. There were correlations between water sampling depth and chemical parameters, and between arsenic concentration and chemical parameters, however, the trends were not always consistent in both wells. ?? 2003 Elsevier Science Ltd.

    The dynamics of newly established elk (Cervus elaphus) populations can provide insights about maximum sustainable rates of reproduction, survival, and increase. However, data used to estimate rates of increase typically have been limited to counts and rarely have included complementary estimates of vital rates. Complexities of population dynamics cannot be understood without considering population processes as well as population states. We estimated pregnancy rates, survival rates, age ratios, and sex ratios for reintroduced elk at Theodore Roosevelt National Park, North Dakota, USA; combined vital rates in a population projection model; and compared model projections with observed elk numbers and population ratios. Pregnancy rates in January (early in the second trimester of pregnancy) averaged 54.1% (SE = 5.4%) for subadults and 91.0% (SE = 1.7%) for adults, and 91.6% of pregnancies resulted in recruitment at 8 months. Annual survival rates of adult females averaged 0.96 (95% CI = 0.94-0.98) with hunting included and 0.99 (95% CI = 0.97-0.99) with hunting excluded from calculations. Our fitted model explained 99.8% of past variation in population estimates and represents a useful new tool for short-term management planning. Although we found no evidence of temporal variation in vital rates, variation in population composition caused substantial variation in projected rates of increase (??=1.20-1.36). Restoring documented hunter harvests and removals of elk by the National Park Service led to a potential rate of ?? = 1.26. Greater rates of increase substantiated elsewhere were within the expected range of chance variation, given our model and estimates of vital rates. Rates of increase realized by small elk populations are too variable to support inferences about habitat quality or density dependence.

    Sheep were among the first domesticated animals to appear in Estonia in the late Neolithic and became one of the most widespread livestock species in the region from the Late Bronze Age onwards. However, the origin and historical expansion of local sheep populations in Estonia remain poorly understood. Here, we analysed fragments of the hypervariable D-loop of mitochondrial DNA (mtDNA; 213 bp) and the Y-chromosome SRY gene (130 bp) extracted from 31 archaeological sheep bones dated from approximately 800 BC to 1700 AD. The ancient DNA data of sheep from Estonia were compared with ancient sheep from Finland as well as a set of contemporary sheep breeds from across Eurasia in order to place them in a wider phylogeographical context. The analysis shows that: (i) 24 successfully amplified and analysed mtDNA sequences of ancient sheep cluster into two haplogroups, A and B, of which B is predominant; (ii) four of the ancient mtDNA haplotypes are novel; (iii) higher mtDNA haplotype diversity occurred during the Middle Ages as compared to other periods, a fact concordant with the historical context of expanding international trade during the Middle Ages; (iv) the proportion of rarer haplotypes declined during the expansion of sheep from the Near Eastern domestication centre to the northern European region; (v) three male samples showed the presence of the characteristic northern European haplotype, SNP G-oY1 of the Y-chromosome, and represent the earliest occurrence of this haplotype. Our results provide the first insight into the genetic diversity and phylogeographical background of ancient sheep in Estonia and provide basis for further studies on the temporal fluctuations of ancient sheep populations.

  17. Independent NOAA considered

    NASA Astrophysics Data System (ADS)

    Richman, Barbara T.

    A proposal to pull the National Oceanic and Atmospheric Administration (NOAA) out of the Department of Commerce and make it an independent agency was the subject of a recent congressional hearing. Supporters within the science community and in Congress said that an independent NOAA will benefit by being more visible and by not being tied to a cabinet-level department whose main concerns lie elsewhere. The proposal's critics, however, cautioned that making NOAA independent could make it even more vulnerable to the budget axe and would sever the agency's direct access to the President.The separation of NOAA from Commerce was contained in a June 1 proposal by President Ronald Reagan that also called for all federal trade functions under the Department of Commerce to be reorganized into a new Department of International Trade and Industry (DITI).

    Experiences of stigma are often associated with negative mental and physical health outcomes. The present work tested the associations between stigma and health-related outcomes among people with HIV who inject drugs in Kohtla-Järve, Estonia and St. Petersburg, Russia. These two cities share some of the highest rates of HIV outside of sub-Saharan Africa, largely driven by injection drug use, but Estonia has implemented harm reduction services more comprehensively. People who inject drugs were recruited using respondent-driven sampling; those who indicated being HIV-positive were included in the present sample (n = 381 in St. Petersburg; n = 288 in Kohtla-Järve). Participants reported their health information and completed measures of internalized HIV stigma, anticipated HIV stigma, internalized drug stigma, and anticipated drug stigma. Participants in both locations indicated similarly high levels of all four forms of stigma. However, stigma variables were more strongly associated with health outcomes in Russia than in Estonia. The St. Petersburg results were consistent with prior work linking stigma and health. Lower barriers to care in Kohtla-Järve may help explain why social stigma was not closely tied to negative health outcomes there. Implications for interventions and health policy are discussed.

    The aim of the current project was to develop an Internet-based recruitment system for HIV and sexually transmitted infection (STI) screening for men who have sex with men (MSM) in Estonia in order to collect biological samples during behavioural studies. In 2013, an Internet-based HIV risk-behaviour survey was conducted among MSM living in Estonia. After completing the questionnaire, all participants were offered anonymous and free-of-charge STI testing. They could either order a urine sample kit by post to screen for chlamydia infections (including lymphogranuloma venereum (LGV)), trichomoniasis, gonorrhoea and Mycoplasma genitalium infections, or visit a laboratory for HIV, hepatitis A virus, hepatitis B virus,hepatitis C virus and syphilis screening. Of 301 participants who completed the questionnaire, 265 (88%),reported that they were MSM. Of these 265 MSM,68 (26%) underwent various types of testing. In the multiple regression analysis, Russian as the first language,previous HIV testing and living in a city or town increased the odds of testing during the study. Linking Internet-based behavioural data collection with biological sample collection is a promising approach. As there are no specific STI services for MSM in Estonia,this system could also be used as an additional option for anonymous and free-of-charge STI screening. PMID:25953131

    PURPOSE Physicians prescribing new medications often do not convey important medication-related information. This study tests an intervention to improve physician-patient communication about newly prescribed medications. METHODS We conducted a controlled clinical trial of patients in 3 primary care practices, combining data from patient surveys with audio-recorded physician-patient interactions. The intervention consisted of a 1-hour physician-targeted interactive educational session encouraging communication about 5 basic elements regarding a new prescription and a patient information handout listing the 5 basic elements. Main outcome measures were the Medication Communication Index (MCI), a 5-point index assessed by qualitative analysis of audio-recorded interactions (giving points for discussion of medication name, purpose, directions for use, duration of use, and side effects), and patient ratings of physician communication about new prescriptions. RESULTS Twenty-seven physicians prescribed 113 new medications to 82 of 256 patients. The mean MCI for medications prescribed by physicians in the intervention group was 3.95 (SD = 1.02), significantly higher than that for medications prescribed by control group physicians (2.86, SD = 1.23, P <.001). This effect held regardless of medication type (chronic vs nonchronic medication). Counseling about 3 of the 5 MCI components was significantly higher for medications prescribed by physicians in the intervention group, as were patients’ ratings of new medication information transfer (P = .02). Independent of intervention or control groups, higher MCI scores were associated with better patient ratings about information about new prescriptions (P = .003). CONCLUSIONS A physician-targeted educational session improved the content of and enhanced patient ratings of physician communication about new medication prescriptions. Further work is required to assess whether improved communication stimulated by the intervention

    The annual international conference Functional Materials and Nanotechnologies (FM&NT) was started in 2006 by scientists from the Institute of Solid State Physics, University of Latvia. The warm welcome and open atmosphere of this scientific conference has turned it into an event where people from different countries and different fields come and meet under the shared umbrella of functional materials and nanotechnology. It is particularly important for early stage scientists who are looking for new knowledge and contacts with people from various fields to build their own network. Our Latvian colleagues, with their success in internationalization, made us neighbouring Estonians so jealous that we could not help but propose organising the conference every second year in Estonia. In a way, this conference is a continuation of the idea of the famous Baltic seminars which took place over several decades in the last century. Due to political constraints, these seminars were only open to scientists of former Eastern Europe countries, but had a great popularity and attendance from over the whole Soviet Union. Many collaborations started from the initial personal contact between scientists at these twice yearly seminars, held alternately in Latvia and Estonia. At the FM&NT 2012 conference, the decision was made that Institute of Physics, University of Tartu would organise the next event in Tartu in 2013. FM&NT-2013 was hence held in Tartu (Estonia) from 21-24 April 2013 at the Dorpat Conference Centre. The main selected topics of the conference were: (i) multifunctional materials, (ii) nanomaterials, (iii) materials for sustainable energy applications and (vi) theory. Additionally, the focus in this conference was on studies with the help of synchrotron radiation and other novel light sources such as free electron lasers. The conference provided an opportunity for 300 scientists from 21 countries to meet, establish contacts, exchange knowledge and discuss their research

  8. Agent independent task planning

    Davis, William S.

    1990-01-01

    Agent-Independent Planning is a technique that allows the construction of activity plans without regard to the agent that will perform them. Once generated, a plan is then validated and translated into instructions for a particular agent, whether a robot, crewmember, or software-based control system. Because Space Station Freedom (SSF) is planned for orbital operations for approximately thirty years, it will almost certainly experience numerous enhancements and upgrades, including upgrades in robotic manipulators. Agent-Independent Planning provides the capability to construct plans for SSF operations, independent of specific robotic systems, by combining techniques of object oriented modeling, nonlinear planning and temporal logic. Since a plan is validated using the physical and functional models of a particular agent, new robotic systems can be developed and integrated with existing operations in a robust manner. This technique also provides the capability to generate plans for crewmembers with varying skill levels, and later apply these same plans to more sophisticated robotic manipulators made available by evolutions in technology.

  9. International exploration by independents

    1991-03-01

    Recent industry trends indicate that the smaller US independents are looking at foreign exploration opportunities as one of the alternatives for growth in the new age of exploration. It is usually accepted that foreign finding costs per barrel are substantially lower than domestic because of the large reserve potential of international plays. To get involved overseas requires, however, an adaptation to different cultural, financial, legal, operational, and political conditions. Generally foreign exploration proceeds at a slower pace than domestic because concessions are granted by the government, or are explored in partnership with the national oil company. First, a mid- to long-term strategy, tailored to the goals and the financial capabilities of the company, must be prepared; it must be followed by an ongoing evaluation of quality prospects in various sedimentary basins, and a careful planning and conduct of the operations. To successfully explore overseas also requires the presence on the team of a minimum number of explorationists and engineers thoroughly familiar with the various exploratory and operational aspects of foreign work, having had a considerable amount of onsite experience in various geographical and climatic environments. Independents that are best suited for foreign expansion are those that have been financially successful domestically, and have a good discovery track record. When properly approached foreign exploration is well within the reach of smaller US independents and presents essentially no greater risk than domestic exploration; the reward, however, can be much larger and can catapult the company into the big leagues.

    Background We sought to identify factors associated with newly detected human papillomavirus (HPV) infection in a high-risk cohort of injection drug using women in Baltimore, MD. Methods We studied 146 HIV-infected and 73 HIV-uninfected female participants in a 5-year prospective HIV natural history study. We examined the association of sexual and nonsexual risk factors and newly detected type-specific HPV infection as determined by consensus PCR between consecutive visits. Results Newly detected HPV was more common among HIV-infected versus HIV-uninfected women (30% and 6%, respectively; P <0.01). Among the entire cohort, recent crack use (OR, 1.7; 95% CI, 1.1−2.6) and HIV infection/CD4 cell count were independent predictors for new HPV detection (HIV-uninfected as reference, OR, 4.6; 95% CI, 2.3−8.9, OR, 5.4; 95% CI, 2.8−10.3, and OR, 10.9; 95% CI, 5.5−21.7 for HIV-infected CD4 >500, 200−500, and <200, respectively). Among HIV-uninfected women, recent marijuana use was an independent predictor of newly detected HPV infection (OR, 3.5; 95% CI, 1.3−9.5). Conclusions Newly detected HPV clearly increased with greater immunosuppression in HIV-infected injection drug users. Larger studies of HIV-uninfected and infected high-risk individuals are needed to clarify the independent associations of crack and marijuana use with new (or reactivated) HPV infection.

  12. Victimization: a newly recognized outcome of prematurity.

    Victimization by peers affects 10 to 20% of school children under the age of 12 years. Physical, verbal, and psychological victimization (being pushed, hit, called names, teased, being the target of rumours, theft, extortion) is associated with short- and long-term adjustment problems, such as peer rejection, social withdrawal, low self-esteem, anxiety, loneliness, and depression, as well as academic problems and school drop-out. Research on populations of school children (primary and secondary) has associated victimization with personal risk factors (the victim's characteristics and behaviour) and interpersonal risk factors (social relationships between peers). Studies on the social adjustment of preterm children at school age show that, even in the absence of a major motor or cognitive disability, this population has several personal risk factors associated with victimization. The objective of this study was to compare the level of victimization experienced by a group of 96 seven-year-old children born extremely preterm (EP, < 29 weeks of gestation; 49 females) against that experienced by a group of 63 term children (34 females) matched for age and sex, maternal level of education, and family socioeconomic status. The children born EP had a mean gestational age of 27.3 weeks (SD 1.2) and a mean birthweight of 1001.1g (SD 223) and normal birthweight children had a mean gestational age of 39.5 weeks (SD 1.5) and a mean birthweight of 3468.7g (SD 431). Physical and verbal victimization were assessed in a school setting by peers with individual sociometric interviews (Modified Peer Nomination Inventory). After controlling for physical growth (height and weight) at the age of 7 years, the data indicate two independent effects: males were more victimized than females, and children born preterm experienced more verbal victimization by their peers than their term classmates, even when participants with a visible motor, intellectual, or sensory disability were excluded

    During two measurement campaigns, from August to September 2008 and 2009, we quantified the major ecosystem fluxes in a hemiboreal forest ecosystem in Järvselja, Estonia. The main aim of this study was to separate the ecosystem flux components and gain insight into the performance of a multi-species multi-layered tree stand. Carbon dioxide and water vapor fluxes were measured using the eddy covariance method above and below the canopy in conjunction with the microclimate. Leaf and soil contributions were quantified separately by cuvette and chamber measurements, including fluxes of carbon dioxide, water vapor, nitrogen oxides, nitrous oxide, methane, ozone, sulfur dioxide, and biogenic volatile organic compounds (isoprene and monoterpenes). The latter have been as well characterized for monoterpenes in detail. Based on measured atmospheric trace gas concentrations, the flux tower site can be characterized as remote and rural with low anthropogenic disturbances. Our results presented here encourage future experimental efforts to be directed towards year round integrated biosphere-atmosphere measurements and development of process-oriented models of forest-atmosphere exchange taking the special case of a multi-layered and multi-species tree stand into account. As climate change likely leads to spatial extension of hemiboreal forest ecosystems a deep understanding of the processes and interactions therein is needed to foster management and mitigation strategies.

    This paper presents the first topological analysis of the economic structure of an entire country based on payments data obtained from Swedbank. This data set is exclusive in its kind because around 80% of Estonia's bank transactions are done through Swedbank, hence, the economic structure of the country can be reconstructed. Scale-free networks are commonly observed in a wide array of different contexts such as nature and society. In this paper, the nodes are comprised by customers of the bank (legal entities) and the links are established by payments between these nodes. We study the scaling-free and structural properties of this network. We also describe its topology, components and behaviors. We show that this network shares typical structural characteristics known in other complex networks: degree distributions follow a power law, low clustering coefficient and low average shortest path length. We identify the key nodes of the network and perform simulations of resiliency against random and targeted attacks of the nodes with two different approaches. With this, we find that by identifying and studying the links between the nodes is possible to perform vulnerability analysis of the Estonian economy with respect to economic shocks.

    The Soontaga Forest Station is located in hemi-boreal 200-years old pine forest (South Estonia; 58o01'N 26o04'E) with a second layer of spruce. The station has the instrumentation to assess the exchange of carbon dioxide (net ecosystem exchange, NEE), soil respiration, tree biomass (above and below ground biomass) and different environmental and meteorological parameters. In this study we quantified carbon balance by analyzing eddy-covariance CO2 flux data (carbon exchange) vs chamber-based measurements (ecosystem respiration) and CO2assimilation (soil and biomass). The annual NEE in this mature coniferous forest was -2.3 t C ha yr-1, showing a clear diurnal and seasonal trend. During the daytime in summer the forest sequestered CO2, while during the night and late night CO2 emitted from the ecosystem to the atmosphere. Within the growing period, the sequestration of CO2 by plants was greater than soil respiration. Thus, the ecosystem sequestered carbon. Most of the carbon is bound in tree biomass (above and below ground biomass) but as well into soil, while the sequestration in soil increases with stand age. In addition, the biomass of understory, especially belowground litter, is playing essential part in carbon input. A modelling approach of long-term C budget in the Soontaga pine forest is presented.

    A comprehensive investigation of the chemical composition of the aerial parts of Hypericum perforatum L. collected in three habitations in Estonia was carried out. An analysis by gas chromatography-mass spectrometry and gas chromatography-flame ionisation detection established the main components of the essential oils. The phenolic compounds both in ethanol and water extracts of the plant were analysed using liquid chromatography-mass spectrometry (LC-MS) and capillary zone electrophoresis. In addition to the earlier published polyphenols, several new phenolic acids and flavonoids, such as quercetin hexoside malonates and an A-type catechin-epicatechin trimer were identified in this Hypericum for the first time. The contents of the pharmaceutically important antidepressants hyperforin and hypericin were also estimated by LC-MS and compared with the data in the literature. The composition of the mineral elements was determined by atomic absorption spectroscopy. The results of the study demonstrate a rather high variability in the content of different substance groups in H. perforatum L. and, hence, the need for a survey of the raw material in the course of selection of raw materials for pharmaceutical preparations.

    The Kärdla marine impact structure (Estonia, 58°58'N, 22°46'E) was formed at 455 Ma (Upper Ordovician), in a shallow epicontinental sea some tens of kilometres from the land and erosion area. The iron-rich projectile about 200 m in diameter approached from the west at an angle of 30-45°. The impactor penetrated about 50-m-thick water layer and the sedimentary cover and exploded in the uppermost part of the crystalline basement. A complex crater, 4 km wide and about 500 m deep, with a central uplift rising 130 m from the crater floor, was formed. The highest point of the rimwall is 110 m above the target level. The rimwall is cut by at least two resurge-excavated gullies. The variable height of the rimwall obviously results from the obliqueness of the impact. Outside the crater an elliptical area was revealed, 12-15 km in diameter, with deformed sedimentary rocks below the target level. The elliptical shape of this area may also be due to the oblique impact. Because the crater and its surroundings were buried directly after the impact, the whole complex of impact-related sediments is preserved there. They are recovered by 160 wells, six of which penetrate the entire complex of impact breccias inside the crater.

    The Paldiski Nuclear Facility in Estonia, with two nuclear reactors was owned by the Soviet Navy and was used for training the navy personnel to operate submarine nuclear reactors. After collapse of Soviet Union the Facility was shut down and handed over to the Estonian government in 1995. In co-operation with the Paldiski International Expert Reference Group (PIERG) decommission strategy was worked out and started to implement. Conditioning of solid and liquid operational waste and dismantling of contaminated installations and buildings were among the key issues of the Strategy. Most of the liquid waste volume, remained at the Facility, was processed in the frames of an Estonian-Finnish co-operation project using a mobile wastewater purification unit NURES (IVO International OY) and water was discharged prior to the site take-over. In 1999-2002 ca 120 m{sup 3} of semi-liquid tank sediments (a mixture of ion exchange resins, sand filters, evaporator and flocculation slurry), remained after treatment of liquid waste were solidified in steel containers and stored into interim storage. The project was carried out under the Swedish - Estonian co-operation program on radiation protection and nuclear safety. Contaminated installations in buildings, used for treatment and storage of liquid waste (Liquid Waste Treatment Facility and Liquid Waste Storage) were then dismantled and the buildings demolished in 2001-2004.

    On August 8, 2010, a derecho swept over Northern Europe, causing widespread wind damage and more than 2 million Euros in economic loss in Estonia during its most destructive stage. This paper presents a modelling study of the derecho-producing storm utilising the Hirlam Aladin Research for Mesoscale Operational Numerical Weather Prediction in Europe (HARMONIE) model. The model setup is chosen to mimic near-future, nearly kilometre-scale, operational environments in European national weather services. The model simulations are compared to remote sensing and in situ observations. The HARMONIE model is capable of reproducing the wind gust severity and precipitation intensity. Moreover, 2.5-km grid spacing is shown to be sufficient for producing a reliable signal of the severe convective storm. Storm dynamics are well simulated, including the rear inflow jet. Although the model performance is promising, a strong dependence on the initial data, a weak trailing stratiform precipitation region and an incorrect timing of the storm are identified.

    Total flavonoid contents in the inflorescences of different varieties of Calendula officinalis L. were investigated. The commercial seeds (20 samples) of varieties of C. officinalis originating from eight European countries were cultivated in home gardens in two different counties of Estonia. Total flavonoid contents, determined spectrophotometrically (λ = 370 nm), varied from each other by more than three times (0.21-0.68%) in the investigated varieties. The variety with the highest flavonoid content was 'Kablouna', produced by the Finnish company Siemen (0.68%). Other varieties with high flavonoid content, such as 'Touch of Red' produced by the Latvian company Kurzemes Seklas (0.55%), 'Golden Emperor' produced by the Finnish company Suvipiha (0.50%), 'Pomyk' from Poland (0.50%), etc., may also be preferred for cultivation as natural sources, as they are also rich in flavonoids. The amount of total flavonoids depends on the variety and/or the place and time of cultivation. There appeared to be no conclusive relationship between the total flavonoid content and the colour of ligulate and tubular florets of C. officinalis.

    The aim of the cross-sectional study was to evaluate the pattern of complementary self-treatment with P. ginseng and its analogues amongst pharmacy customers in Estonia. The study instrument consisted of multiple-choice items related to personal knowledge about and experience with the use of P. ginseng and its analogues. In total, 1233 customers participated in the study. Of study participants, 18.1% reported the use of P. ginseng and its analogues in their lives. P. ginseng preparations were used mostly according to the well- known indications (tiredness, weakness and decreased mental and physical capacity). Of P. ginseng users 44.3% reported positive treatment effects and 12.0% had experienced different side effects. With increase of age (p < 0.01) and at lower levels of education (p = 0.04), the use of ginseng or its analogues decreased. The better the users evaluated their health, the better they perceived the effect of P. ginseng preparations (p < 0.01). This study reported rather frequent use of P. ginseng and its analogues. P. ginseng could be seen in the treatment of conditions, where the use of local medicinal plants has not been established. Further research is needed to learn more about public knowledge and experiences about efficacy and safety of P. ginseng and its analogues. PMID:27476299

The better the users evaluated their health, the better they perceived the effect of P. ginseng preparations (p < 0.01). This study reported rather frequent use of P. ginseng and its analogues. P. ginseng could be seen in the treatment of conditions, where the use of local medicinal plants has not been established. Further research is needed to learn more about public knowledge and experiences about efficacy and safety of P. ginseng and its analogues.

    The Soontaga Forest Station is located in hemi-boreal 200-years old pine forest (South Estonia; 58o01'N 26o04'E) with a second layer of spruce. The station has the instrumentation to assess the exchange of carbon dioxide (net ecosystem exchange, NEE), soil respiration, tree biomass (above and below ground biomass) and different environmental and meteorological parameters. In this study we quantified carbon balance by analyzing eddy-covariance CO2 flux data (carbon exchange) vs chamber-based measurements (ecosystem respiration) and CO2assimilation (soil and biomass). The annual NEE in this mature coniferous forest was -2.3 t C ha yr‑1, showing a clear diurnal and seasonal trend. During the daytime in summer the forest sequestered CO2, while during the night and late night CO2 emitted from the ecosystem to the atmosphere. Within the growing period, the sequestration of CO2 by plants was greater than soil respiration. Thus, the ecosystem sequestered carbon. Most of the carbon is bound in tree biomass (above and below ground biomass) but as well into soil, while the sequestration in soil increases with stand age. In addition, the biomass of understory, especially belowground litter, is playing essential part in carbon input. A modelling approach of long-term C budget in the Soontaga pine forest is presented.

    Neurotransmission relies on the calcium-triggered exocytic fusion of non-peptide neurotransmitter-containing small synaptic vesicles (SVs) with the presynaptic membrane at active zones (AZs) followed by compensatory endocytic retrieval of SV membranes. Here, we study the diffusional fate of newly exocytosed SV proteins in hippocampal neurons by high-resolution time-lapse imaging. Newly exocytosed SV proteins rapidly disperse within the first seconds post fusion until confined within the presynaptic bouton. Rapid diffusional spread and confinement is followed by slow reclustering of SV proteins at the periactive endocytic zone. Confinement within the presynaptic bouton is mediated in part by SV protein association with the clathrin-based endocytic machinery to limit diffusional spread of newly exocytosed SV proteins. These data suggest that diffusion, and axonal escape of newly exocytosed vesicle proteins, are counteracted by the clathrin-based endocytic machinery together with a presynaptic diffusion barrier.

    Essential hypertension is characterized by a left ventricular dysfunction. However, the majority of the studies performed so far investigated patients under drug treatment and/or with concomitant diseases, such as obesity, diabetes, metabolic syndrome or coronary heart disease, which per se may affect diastolic function independently on the blood pressure elevation. The present study aimed at investigating left ventricular diastolic function in untreated, uncomplicated and newly diagnosed hypertensive patients by employing both routine echo-Doppler and pulse tissue-Doppler technique. Data were collected in 86 middle-aged essential hypertensive patients and in 18 sex-matched normotensive controls. At the echo-Doppler approach, about half of the hypertensive patients displayed a diastolic dysfunction (n = 44, E/A: 0.79 ± 0.02). They showed body mass index values slightly greater than hypertensive patients without diastolic dysfunction but superimposable blood pressure values and metabolic variables. When assessed via the pulse tissue-Doppler approach, patients with a reduced E/A displayed an Em/Am ratio significantly lower than patients without diastolic dysfunction and control subjects. This was the case when the data were related to the lateral and septal mitral annulus or averaged together. Furthermore, whereas myocardial systolic peak velocity (Sm) was lower in hypertensive patients than in control subjects, no significant between-groups difference in E/Em ratio was observed. Differently from the data obtained via the echo-Doppler approach, the tissue-Doppler method in patients without diastolic dysfunction showed a significant higher deceleration and isovolumetric relaxation times, with a lower Em velocity compared with the normotensive subjects. At the stepwise multiple regression analysis E/A ratio and E'/A' values were related with left ventricular mass index and body mass index after correction for age. These data provide evidence that diastolic

    . CR duration was significantly longer with early onset of CR and favorable karyotypes. Time-dependent covariate analysis suggested that timely application of a second transplant extended both EFS and OS significantly, independent of cytogenetics and beta-2-microglobulin. Total Therapy represents a comprehensive treatment approach for newly diagnosed myeloma patients, using multi-regimen induction and tandem transplantation followed by interferon maintenance. As a result, the proportion of patients attaining CR increased progressively with continuing therapy. This observation is particularly important because CR is a sine qua non for long-term disease control and, eventually, cure.

    We compute the third order gauge invariant action for scalar-graviton interactions in the Jordan frame. We demonstrate that the gauge invariant action for scalar and tensor perturbations on one physical hypersurface only differs from that on another physical hypersurface via terms proportional to the equation of motion and boundary terms, such that the evolution of non-Gaussianity may be called unique. Moreover, we demonstrate that the gauge invariant curvature perturbation and graviton on uniform field hypersurfaces in the Jordan frame are equal to their counterparts in the Einstein frame. These frame independent perturbations are therefore particularly useful in relating results in different frames at the perturbative level. On the other hand, the field perturbation and graviton on uniform curvature hypersurfaces in the Jordan and Einstein frame are non-linearly related, as are their corresponding actions and n-point functions.

    2006-01-01

    Trends in the time series of air temperature, precipitation, snow cover duration and onset of climatic seasons at ten stations in Estonia during 1951-2000 are analysed. Using the conditional Mann-Kendall test, these trends are compared with trends in the characteristics of large-scale atmospheric circulation: the NAO and AO indices, frequency of circulation forms according to the Vangengeim-Girs’ classification, and the northern hemisphere teleconnection indices. The objective of the study is to estimate the influence of trends in circulation on climate changes in Estonia. Statistically significant increasing trends in air temperature are detected in January, February, March, April and May, in winter (DJF), spring (MAM) and in the cold period (NDJFM). The trends in precipitation, as a rule, differ from station to station. Increasing trends are present during the cold half-year - from October until March - and also in June. Snow cover duration has decreased in Estonia by 17-20 days inland and by 21-36 days on the coast. The onsets of early spring and spring have shifted to an earlier date. Some important changes have occurred in the parameters of atmospheric circulation during 1951-2000. Intensity of zonal circulation, i.e. westerlies, has increased during the cold period, especially in February and March. Results of the conditional Mann-Kendall test indicate that the intensification of westerlies in winter is significantly related to climate changes in winter and also in spring. A negative trend in the East Atlantic Jet (EJ) index, i.e. the weakening of the westerlies in May has caused warming during that month. Decrease in northerly circulation, i.e. in frequency of circulation form C and in East Atlantic/West Russia teleconnection index (EW) is related to an increase in precipitation in October.

We examined such beliefs in student samples (total N = 686) from Estonia, Malaysia, Romania, the United Kingdom, and the United States with the Beliefs in the Inheritance of Risk Factors for Suicide Scale. Cultural effects were small, those of key demographics nil. Several facets of construct validity were demonstrated. Marked differences in perceived plausibility of evidence about the genetics of suicide according to research design, observed in all samples, may be of general interest for investigating lay theories of abnormal behavior and communicating behavioral and psychiatric genetic research findings.

    light years from Earth. These results do not rely on the traditional distance ladder. Bonamente and his colleagues find the Hubble constant to be 77 kilometers per second per megaparsec (a megaparsec is equal to 3.26 million light years), with an uncertainty of about 15%. This result agrees with the values determined using other techniques. The Hubble constant had previously been found to be 72, give or take 8, kilometers per second per megaparsec based on Hubble Space Telescope observations. The new Chandra result is important because it offers the independent confirmation that scientists have been seeking and fixes the age of the Universe between 12 and 14 billion years. Chandra X-ray Image of CL J1226.9+3332 Chandra X-ray Image of CL J1226.9+3332 "These new results are entirely independent of all previous methods of measuring the Hubble constant," said team member Marshall Joy also of MSFC. The astronomers used a phenomenon known as the Sunyaev-Zeldovich effect, where photons in the cosmic microwave background (CMB) interact with electrons in the hot gas that pervades the enormous galaxy clusters. The photons acquire energy from this interaction, which distorts the signal from the microwave background in the direction of the clusters. The magnitude of this distortion depends on the density and temperature of the hot electrons and the physical size of the cluster. Using radio telescopes to measure the distortion of the microwave background and Chandra to measure the properties of the hot gas, the physical size of the cluster can be determined. From this physical size and a simple measurement of the angle subtended by the cluster, the rules of geometry can be used to derive its distance. The Hubble constant is determined by dividing previously measured cluster speeds by these newly derived distances.

    The plant hormone abscisic acid (ABA) regulates many key processes in plants, including seed germination and development and abiotic stress tolerance, particularly drought resistance. Understanding early events in ABA signal transduction has been a major goal of plant research. The recent identification of the PYRABACTIN (4-bromo-N-[pyridin-2-yl methyl]naphthalene-1-sulfonamide) RESISTANCE (PYR)/REGULATORY COMPONENT OF ABA RECEPTOR (RCAR) family of ABA receptors and their biochemical mode of action represents a major breakthrough in the field. The solving of PYR/RCAR structures provides a context for resolving mechanisms mediating ABA control of protein–protein interactions for downstream signaling. Recent studies show that a pathway based on PYR/RCAR ABA receptors, PROTEIN PHOSPHATASE 2Cs (PP2Cs), and SNF1-RELATED PROTEIN KINASE 2s (SnRK2s) forms the primary basis of an early ABA signaling module. This pathway interfaces with ion channels, transcription factors, and other targets, thus providing a mechanistic connection between the phytohormone and ABA-induced responses. This emerging PYR/RCAR–PP2C–SnRK2 model of ABA signal transduction is reviewed here, and provides an opportunity for testing novel hypotheses concerning ABA signaling. We address newly emerging questions, including the potential roles of different PYR/RCAR isoforms, and the significance of ABA-induced versus constitutive PYR/RCAR–PP2C interactions. We also consider how the PYR/RCAR–PP2C–SnRK2 pathway interfaces with ABA-dependent gene expression, ion channel regulation, and control of small molecule signaling. These exciting developments provide researchers with a framework through which early ABA signaling can be understood, and allow novel questions about the hormone response pathway and possible applications in stress resistance engineering of plants to be addressed.

    The annual international conference Functional Materials and Nanotechnologies (FM&NT) was started in 2006 by scientists from the Institute of Solid State Physics, University of Latvia. The warm welcome and open atmosphere of this scientific conference has turned it into an event where people from different countries and different fields come and meet under the shared umbrella of functional materials and nanotechnology. It is particularly important for early stage scientists who are looking for new knowledge and contacts with people from various fields to build their own network. Our Latvian colleagues, with their success in internationalization, made us neighbouring Estonians so jealous that we could not help but propose organising the conference every second year in Estonia. In a way, this conference is a continuation of the idea of the famous Baltic seminars which took place over several decades in the last century. Due to political constraints, these seminars were only open to scientists of former Eastern Europe countries, but had a great popularity and attendance from over the whole Soviet Union. Many collaborations started from the initial personal contact between scientists at these twice yearly seminars, held alternately in Latvia and Estonia. At the FM&NT 2012 conference, the decision was made that Institute of Physics, University of Tartu would organise the next event in Tartu in 2013. FM&NT-2013 was hence held in Tartu (Estonia) from 21-24 April 2013 at the Dorpat Conference Centre. The main selected topics of the conference were: (i) multifunctional materials, (ii) nanomaterials, (iii) materials for sustainable energy applications and (vi) theory. Additionally, the focus in this conference was on studies with the help of synchrotron radiation and other novel light sources such as free electron lasers. The conference provided an opportunity for 300 scientists from 21 countries to meet, establish contacts, exchange knowledge and discuss their research

    2012-06-01

    Passionate love is associated with increased activity in dopamine-rich regions of the brain. Increased dopamine in these regions is associated with a greater tendency to learn from reward in trial-and-error learning tasks. This study examined the prediction that individuals who were newly in love would be better at responding to reward (positive feedback). In test trials, people who were newly in love selected positive outcomes significantly more often than their single (not in love) counterparts but were no better at the task overall. This suggests that people who are newly in love show a bias toward responding to positive feedback, which may reflect a general bias towards reward-seeking.

    Periodontal regenerative techniques have been proposed; however, the outcomes remain debatable. The present investigation assessed the regenerated cementum following enamel matrix derivative application in dehiscence-type defects. Buccal osseous dehiscences were surgically created on the maxillary cuspid, and the second and fourth premolars in five female beagle dogs. The treatment group (n=15 sites) received the enamel matrix derived application, whereas the control groups (n=15) did not. The dogs were sacrificed 4 months following treatment and the specimens were histologically and histometrically examined. The newly formed cementum was uneven in thickness and mineralization, overlapped the old cementum and exhibited functional orientation, cementocyte lacunae and collagen fibril bundles. Most of the histological specimens showed the presence of a gap between the newly formed cementum and the underlying dentin. Control sites did not exhibit any cementum formation. The present study concluded that newly formed cementum is of cellular type and exhibits multiple characteristics. PMID:21449212

    Altogether, 343 adult and 111 nymphal Ixodes ricinus ticks collected from parks in Turku and suburban and rural islands of the Turku archipelago, Finland, and 100 adult I. ricinus ticks collected from Vormsi Island, Estonia, were included in this study. Using the polymerase chain reaction the ticks were examined for 16S rDNA of the Ehrlichia phagocytophila genogroup and for Borrelia burgdorferi sensu lato recA and flagellin genes. None of the Finnish ticks was found to be infected with E. phagocytophila, whereas 3% of the Estonian ticks were positive for this organism. The rate of Finnish ticks infected with B. burgdorferi sensu lato varied from 0% to 11.6% (mean 5%; 9% for adult and 4% for nymphal ticks). The corresponding rate for Estonian ticks was 15%. Borrelia afzelii was the most common genospecies in both Finnish (2.6%) and Estonian (12%) ticks. B. burgdorferi sensu stricto was detected in 2.0% of the Finnish ticks, but in none of the Estonian ticks. These results suggest that the E. phagocytophila genogroup is very rare in Finnish ticks, although the ticks were collected from an area endemic for Lyme borreliosis. In Estonia, E. phagocytophila is found in ticks and may cause disease.

A multiple-choice questionnaire listing 10 plants and posing questions on the perceived characteristics of cold and flu, the effectiveness of plants, help-seeking behaviour, self-treatment and sources of information, was distributed to a sample of participants in two medium size pharmacies. The participants were pharmacy customers: 150 in Tallinn (mostly Russian speaking) and 150 in Kuressaare (mostly Estonian speaking). The mean number of plants used by participants was 4.1. Of the respondents, 69% self-treated the common cold and flu and 28% consulted with a general practitioner. In general, medicinal plants were considered effective in the treatment of the above-mentioned illnesses and 56% of the respondents had used exclusively medicinal plants or their combination with OTC medicines and other means of folk medicine for treatment. The use of medicinal plants increased with age and was more frequent among female than male respondents. Among Estonian-speaking customers lime flowers, blackcurrant and camomile were more frequently used, and among Russian speaking customers raspberry and lemon fruits. Regardless of some statistically significant differences in preferred species among different age, education, sex and nationality groups, the general attitude towards medicinal plants for self-treatment of the common cold and flu in Estonia was very favourable.

    Mast cells are immunoregulatory cells that participate in inflammatory processes. Cross-linking mast cell specific GD1b derived gangliosides by mAbAA4 results in partial activation of mast cells without the release of preformed mediators. The present study examines the release of newly formed and newly synthesized mediators following ganglioside cross-linking. Cross-linking the gangliosides with mAbAA4 released the newly formed lipid mediators, prostaglandins D2 and E2, without release of leukotrienes B4 and C4. The effect of cross-linking these gangliosides on the activation of enzymes in the arachidonate cascade was then investigated. Ganglioside cross-linking resulted in phosphorylation of cytosolic phospholipase A2 and increased expression of cyclooxygenase-2. Translocation of 5-lipoxygenase from the cytosol to the nucleus was not induced by ganglioside cross-linking. Cross-linking of GD1b derived gangliosides also resulted in the release of the newly synthesized mediators, interleukin-4, interleukin-6, and TNF-α. The effect of cross-linking the gangliosides on the MAP kinase pathway was then investigated. Cross-linking the gangliosides induced the phosphorylation of ERK1/2, JNK1/2, and p38 as well as activating both NFκB and NFAT in a Syk-dependent manner. Therefore, cross-linking the mast cell specific GD1b derived gangliosides results in the activation of signaling pathways that culminate with the release of newly formed and newly synthesized mediators.

    Mast cells are immunoregulatory cells that participate in inflammatory processes. Cross-linking mast cell specific GD1b derived gangliosides by mAbAA4 results in partial activation of mast cells without the release of preformed mediators. The present study examines the release of newly formed and newly synthesized mediators following ganglioside cross-linking. Cross-linking the gangliosides with mAbAA4 released the newly formed lipid mediators, prostaglandins D2 and E2, without release of leukotrienes B4 and C4. The effect of cross-linking these gangliosides on the activation of enzymes in the arachidonate cascade was then investigated. Ganglioside cross-linking resulted in phosphorylation of cytosolic phospholipase A2 and increased expression of cyclooxygenase-2. Translocation of 5-lipoxygenase from the cytosol to the nucleus was not induced by ganglioside cross-linking. Cross-linking of GD1b derived gangliosides also resulted in the release of the newly synthesized mediators, interleukin-4, interleukin-6, and TNF-α. The effect of cross-linking the gangliosides on the MAP kinase pathway was then investigated. Cross-linking the gangliosides induced the phosphorylation of ERK1/2, JNK1/2, and p38 as well as activating both NFκB and NFAT in a Syk-dependent manner. Therefore, cross-linking the mast cell specific GD1b derived gangliosides results in the activation of signaling pathways that culminate with the release of newly formed and newly synthesized mediators.

    This report identifies and evaluates three options for treating newly generated liquid waste at the Idaho Nuclear Technology and Engineering Center of the Idaho National Engineering and Environmental Laboratory. The three options are: (a) treat the waste using processing facilities designed for treating sodium-bearing waste, (b) treat the waste using subcontractor-supplied mobile systems, or (c) treat the waste using a special facility designed and constructed for that purpose. In studying these options, engineers concluded that the best approach is to store the newly generated liquid waste until a sodium-bearing waste treatment facility is available and then to co-process the stored inventory of the newly generated waste with the sodium-bearing waste. After the sodium-bearing waste facility completes its mission, two paths are available. The newly generated liquid waste could be treated using the subcontractor-supplied system or the sodium-bearing waste facility or a portion of it. The final decision depends on the design of the sodium-bearing waste treatment facility, which will be completed in coming years.

    Introduction Studies on the prevalence of and risk factors for tuberculosis (TB) among newly diagnosed human immunodeficiency virus (HIV)-infected children in sub-Saharan Africa are scarce and in Nigeria there is paucity of reported data. We determined the prevalence of and risk factors for pulmonary TB (PTB) in newly diagnosed (treatment-naïve) HIV-1 infected children at the pediatric HIV clinic of the Jos University Teaching Hospital (JUTH) in Nigeria. Methods We performed a retrospective analysis of 876 children, aged 2 months – 13 years, diagnosed with HIV-1 infection between July 2005 and December 2012, of which 286 were diagnosed with PTB at presentation after TB screening. The study site was the AIDS Prevention Initiative in Nigeria (APIN)-supported Pediatric HIV clinic at JUTH, Jos. A multivariate forward logistic regression modelling was used to identify risk factors for PTB-HIV co-infection. Results The prevalence of PTB-HIV co-infection was 32% (286/876). Severe immunosuppression (SI) and World Health Organization (WHO) HIV clinical stage 3/4 were identified as independent risk factors for PTB-HIV co-infection in HIV infected children. The odds of PTB-HIV co-infection was increased two-fold in HIV-infected children with WHO clinical stage 3/4 compared to those with stage 1/2 (adjusted odds ratio (AOR) 1.76 [1.31-2.37], p<0.001) and 1.5-fold in children with SI compared to those without SI (AOR 1.52 [1.12-2.06], p=0.007). Conclusion In our setting, the burden of PTB was high among newly diagnosed HIV-infected children, and late WHO HIV clinical stage and severe immunosuppression were associated with PTB-HIV co-infection. Therefore there is a clear need to improve strategies for early diagnosis of both HIV and PTB to optimize clinical outcomes. PMID:27019829

    Background/Aims Antiviral therapy is a key component in the management of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) patients. However, whether the potent drug entecavir is more effective than a less potent drug, such as lamivudine, in HBV-related HCC is not clear. Methods A retrospective cohort of 451 newly diagnosed, HBV-related HCC patients without antiviral therapy at diagnosis, who started antiviral therapy with either entecavir (n=249) or lamivudine (n=202), were enrolled. Results The median survival was longer for the entecavir group than for the lamivudine group, and lamivudine use (vs entecavir) was an independent factor for mortality (hazard ratio [HR], 1.49; p=0.002). Lamivudine use (vs entecavir) was an independent risk factor for new-onset hepatic decompensation (HR, 1.67; p=0.010) in 318 patients without previous hepatic decompensation, and it was also an independent risk factor for recurrence after curative therapy (HR, 1.84; p=0.002) in 117 patients who received curative therapy. The findings were similar in a propensity score-matched cohort. Conclusions Overall survival, decompensation-free survival, and recurrence-free survival were better in the entecavir-treated patients than in the lamivudine treated-patients, indicating that the potent antiviral drug should be the preferred choice in HBV-related HCC patients.

    The study aimed to evaluate the relationship between anthropometric and metabolic indices, inflammatory cytokines, and adipocyte fatty acid-binding protein (A-FABP) in obese patients with newly diagnosed type 2 diabetes. The study included 48 nonobese subjects with newly diagnosed type 2 diabetes, 42 obese subjects with newly diagnosed type 2 diabetes, 30 simple obese subjects, and 30 matched normal subjects. Serum A-FABP was assessed by enzyme-linked immunosorbent assay. Pearson's correlations and multiple linear regression stepwise analysis were used to analyze correlations of A-FABP with anthropometric and metabolic indices and inflammatory cytokines. Obese subjects with newly diagnosed type 2 diabetes had elevated A-FABP compared to normal control, nondiabetic obese patients, and nonobese diabetic patients. A-FABP was significantly correlated with glycated hemoglobin A1C (HbA1C), BMI, triglyceride, Homeostasis Model Assessment Index (HOMA-IR), waist hip rate, C-reactive protein, IL-6, and HDL-C in obese subjects with type 2 diabetes. In multiple linear regression stepwise analysis, BMI, HbA1C, and HOMA-IR were significantly independent determinants for A-FABP. BMI, HbA1C, and HOMA-IR are independently associated with A-FABP in obese subjects with newly diagnosed type 2 diabetes. A-FABP may be related to insulin resistance and inflammation in type 2 diabetes and concomitant obesity.

    2014-05-01

    The knowledge about spectral properties and seasonal dynamics of understory layers in boreal forests currently holds several gaps. This introduces severe uncertainties while modelling the carbon balance of this ecosystem, which is expected to be prone to major shifts with climate change in the future. In this work the seasonal reflectance dynamics in European hemi-boreal forests are studied. The data for this study was collected at Järvselja Training and Experimental Forestry District (Estonia, 27.26°E 58.30°N). Measurements were taken in three different stands. The silver birch (Betula Pendula Roth) stand grows on typical brown gley-soil and its understory vegetation is dominated by a mixture of several grass species. The Scots pine (Pinus sylvestris) stand grows on a bog with understory vegetation composed of sparse labrador tea, cotton grass, and a continuous Sphagnum moss layer. The third stand, Norway spruce (Picea abies), grows on a Gleyi Ferric Podzol site with understory vegetation either partially missing or consisting of mosses such as Hylocomium splendens or Pleurozium schreberi [1]. The sampling design was similar to the study by Rautiainen et al. [3] in northern European boreal forests. At each study site, a 100 m long permanent transect was marked with flags. In addition, four intensive study plots (1 m × 1 m) were marked next to the transects at 20 m intervals. The field campaign lasted from May to September 2013. For each site the fractional cover of understory and understory spectra were estimated ten times i.e. every 2 to 3 weeks. Results from Järvselja forest were compared with the seasonal profiles from boreal forests in Hyytiälä, Finland [2]. References [1] A. Kuusk, M. Lang, J. Kuusk, T. Lükk, T. Nilson, M. Mõttus, M.

    2011-01-01

    Background A previous study found marked differences in smoking between employees in various university faculties in Tartu, Estonia, soon after the disruption of communism. The present study was conducted to see whether such differences still exist and how the patterns had changed during the country's first transitional decade. Methods All employees at the University of Tartu (UT) were surveyed for smoking habits by means of a questionnaire in 1992 and 2003. The present paper is based on respondents whose faculty or workplace was known (1390 people in 1992, 1790 in 2003). Smoking differences were assessed in terms of regression-based adjusted figures. Results While 20% of the male employees smoked daily in 1992, 13% did so in 2003, the figures for females being 10% and 7%, respectively. The prevalence of men's daily smoking varied between faculties and other workplaces in the range 4-30% in 1992, and 0-24% in 2003, with corresponding ranges of 3-21% and 0-10% among females. Men in the medical faculty in both surveys, and those in the faculty of philosophy in the second survey showed higher rates than men in most other faculties, as did women in the faculty of law in the first survey and those in the faculty of philosophy in the second. The figures were usually low in the faculties of sports & exercise, physics & chemistry and mathematics. The sex pattern was reversed in the faculty of law and also in that of economics, where the women smoked more than the men. Conclusions Even in this low-smoking academic community, wide smoking differences existed between the faculties and other workplaces. Faculties where physical or mental performance is of prime importance are leading the way towards a smoke-free community, while men in the faculty of philosophy and, paradoxically, men in the medical faculty are lagging behind. The reversed sex ratio in the faculties of law and economics may indicate women's intensified drive for equality in this transitional society. We assume

    The aim of this article is to evaluate and compare common cattail (Typha latifolia) biomass production and annual accumulation of nitrogen, phosphorus, carbon, and heavy metals (Cd, Cu, Pb, Zn) in phytomass in 3 treatment wetland systems in Estonia. The biomass samples (roots/rhizomes, shoots with leaves, and spadixes) and litter were collected from 1 x 1 m plots--15 plots in Tänassilma seminatural wetland, 15 plots in Põltsamaa constructed wetland, and 10 plots in Häädemeeste constructed wetland. The highest average total cattail phytomass was 2.54 kg DW m(-2) in Häädemeeste. In Tänassilma and Põltsamaa this value was 2.3 and 2.11 kg DW m(-2), respectively. The average total aboveground biomass production and roots/rhizomes phytomass was not significantly different in three studied wetland systems. We have found significantly less spadixes and litter in Tänassilma than in Põltsamaa and Häädemeeste. In Põltsamaa, the N and P content in all plant fractions were higher than in other test areas. The Cd concentration in all samples (shoots, spadixes, litter) varied from < 0.01 to < 0.02 mg/kg. The average concentration of Zn in litter varied from 12.2 mg kg(-1) in Häädemeeste to 12.6 mg kg(-1) in Tänassilma and 13.3 mg kg(-1) in Põltsamaa. There has been found a significantly higher average contents of Cu (39.3 mg kg(-1)), Pb (30.4 mg kg(-1)), and Zn (412.3 mg kg(-1)) in Tänassilma than those in Häädemeeste or Põltsamaa: Cu-11.6 and 15.9, Pb--2.3 and 3.3, and Zn--57.5 and 73.2 mg kg(-1), respectively. The highest heavy metal retention (303.2 mg Pb m(-2), 29.4 mg Zn m(-)2, 22.9 mg Cu m(-2), and 0.35 mg Cd m(-2)) was observed in root and rhizome samples from the Tänassilma wetland.

    Multiple myeloma is a plasma cell disorder characterized by malignant plasma cell infiltration in the bone marrow, serum and/or urine monoclonal protein and organ damage. The aim of this study was to investigate the impact of chromosome 1 abnormalities in a group of elderly patients (>65 years) with newly diagnosed multiple myeloma enrolled in the GIMEMA-MM-03-05 trial and treated with bortezomib, melphalan and prednisone or bortezomib, melphalan, prednisone and thalidomide followed by bortezomib and thalidomide maintenance. We also evaluated the link between chromosome 1 abnormalities and other clinical, genetic and immunophenotypic features by a multivariate logistic regression model. Interphase fluorescence in situ hybridization on immunomagnetically purified plasma cells and bone marrow multiparameter flow cytometry were employed. A multivariate Cox model showed that chromosome 1 abnormalities, age >75 years and a CD19+/CD117− immunophenotype of bone marrow plasma cells were independent risk factors for overall survival in elderly patients with newly diagnosed multiple myeloma. Moreover, a detrimental effect of thalidomide, even when administered in association with bortezomib, was observed in patients with abnormal chromosome 1 as well as in those with 17p deletion, while the benefit of adding thalidomide to the bortezomib-melphalan-prednisone regimen was noted in patients carrying an aggressive CD19+/CD117− bone marrow plasma cell immunophenotype. This trial was registered at www.clinicaltri-als.gov as #NCT01063179. PMID:25015938

  20. Speaker independent acoustic-to-articulatory inversion

    NASA Astrophysics Data System (ADS)

    Ji, An

    Acoustic-to-articulatory inversion, the determination of articulatory parameters from acoustic signals, is a difficult but important problem for many speech processing applications, such as automatic speech recognition (ASR) and computer aided pronunciation training (CAPT). In recent years, several approaches have been successfully implemented for speaker dependent models with parallel acoustic and kinematic training data. However, in many practical applications inversion is needed for new speakers for whom no articulatory data is available. In order to address this problem, this dissertation introduces a novel speaker adaptation approach called Parallel Reference Speaker Weighting (PRSW), based on parallel acoustic and articulatory Hidden Markov Models (HMM). This approach uses a robust normalized articulatory space and palate referenced articulatory features combined with speaker-weighted adaptation to form an inversion mapping for new speakers that can accurately estimate articulatory trajectories. The proposed PRSW method is evaluated on the newly collected Marquette electromagnetic articulography -- Mandarin Accented English (EMA-MAE) corpus using 20 native English speakers. Cross-speaker inversion results show that given a good selection of reference speakers with consistent acoustic and articulatory patterns, the PRSW approach gives good speaker independent inversion performance even without kinematic training data.

  1. Flagellation of Pseudomonas aeruginosa in newly divided cells

    NASA Astrophysics Data System (ADS)

    Zhao, Kun; Lee, Calvin; Anda, Jaime; Wong, Gerard

    2015-03-01

    For monotrichous bacteria, Pseudomonas aeruginosa, after cell division, one daughter cell inherits the old flagellum from its mother cell, and the other grows a new flagellum during or after cell division. It had been shown that the new flagellum grows at the distal pole of the dividing cell when the two daughter cells haven't completely separated. However, for those daughter cells who grow new flagella after division, it still remains unknown at which pole the new flagellum will grow. Here, by combining our newly developed bacteria family tree tracking techniques with genetic manipulation method, we showed that for the daughter cell who did not inherit the old flagellum, a new flagellum has about 90% chances to grow at the newly formed pole. We proposed a model for flagellation of P. aeruginosa.

    Based on genotyping and host range, two newly isolated lytic bacteriophages, myovirus vB_AbaM_Acibel004 and podovirus vB_AbaP_Acibel007, active against Acinetobacter baumannii clinical strains, were selected from a new phage library for further characterization. The complete genomes of the two phages were analyzed. Both phages are characterized by broad host range and essential features of potential therapeutic phages, such as short latent period (27 and 21 min, respectively), high burst size (125 and 145, respectively), stability of activity in liquid culture and low frequency of occurrence of phage-resistant mutant bacterial cells. Genomic analysis showed that while Acibel004 represents a novel bacteriophage with resemblance to some unclassified Pseudomonas aeruginosa phages, Acibel007 belongs to the well-characterized genus of the Phikmvlikevirus. The newly isolated phages can serve as potential candidates for phage cocktails to control A. baumannii infections.

    Identifying collagen produced de novo by cells in a background of purified collagenous biomaterials poses a major problem in for example the evaluation of tissue-engineered constructs and cell biological studies to tumor dissemination. We have developed a universal strategy to detect and localize newly deposited collagen based on its inherent association with dermatan sulfate. The method is applicable irrespective of host species and collagen source. PMID:26738984

    The circulation of newly formed deep water masses (Labrador Sea Water, LSW, and Denmark Strait Overflow Water, DSOW) is examined by discussing the distribution of two parameters (age τ and fraction F of young water) calculated from the chlorofluorocarbon data measured between 1980 and 2005 in the Atlantic. Compared to previous studies, a much larger data set was used with an improved gridding procedure, allowing to resolve the distributions in more detail.

    Purpose Recent studies have demonstrated that hypertension (HTN) is associated with nonalcoholic fatty liver disease (NAFLD) in treated hypertensive patients. The aim of this study was to investigate the association between newly diagnosed essential HTN and NAFLD in untreated hypertensive patients. Patients and methods A consecutive series of 240 subjects (143 hypertensives and 97 normotensives), aged 30–80 years, without diabetes mellitus were enrolled in the study. Subjects with 24-hour systolic blood pressure (SBP) values ≥130 mmHg and/or diastolic BP values ≥80 mmHg were defined as hypertensives. NAFLD was defined as the presence of liver hyperechogenicity on ultrasound. Results Body mass index (P=0.002) and essential HTN (P=0.016) were independently associated with NAFLD in the multivariate logistic regression model. Furthermore, the multivariate analysis revealed that morning SBP (P=0.044) was independently associated with NAFLD. Conclusion Untreated, newly diagnosed essential HTN is independently associated with NAFLD. Ambulatory BP monitoring could be used for the diagnosis of essential HTN in patients with NAFLD.

    The goal of this paper is to estimate the effects of pollution charges, ash handling and of the carbon dioxide quota trade on the competitiveness of natural gas, oil shale, peat and wood chips in Estonia for 2010 and 2015. The pollution charges and levels are calculated based on the Environmental Charges Act, and Regulations No 99/2004 and No 94/2004 of the Estonian Minister of the Environment. The calculations show a considerable change in the cost competitiveness of fuels. Fuel related costs of the fossil fuels with high CO2 emission factors and other environmental impacts may be doubled.

    Extensive folklore records from pre-modern Estonia give us an excellent opportunity to study a variety of local plant knowledge and plant use among the peasantry in various parts of the country. One important biocultural domain where plant knowledge has been crucial was in the various methods of combating different ectoparasites that cohabited and coexisted with humans and their domestic animals. Some of these methods were widely known (world-wide, Eurasia, Europe, Baltic Rim), while others were more local. Here we discuss ways of reducing clothes moths Tineola bisselliella (Hummel) (Lepidoptera: Tineidae), human fleas Pulex irritons L. (Siphonaptera: Pulicidae) and bedbugs Cimex lectularius L. (Hemiptera: Cimicidae) with the help of plants. Various taxa used as traditional repellents have been identified. The use of plants as repellents and their toxic principles are also discussed from a comparative perspective.

    The present study examined biographical factors of occupational independence including any kind of nonemployed profession. Participants were 59 occupationally independent and 58 employed persons of different age (M = 36.3 yr.), sex, and profession. They were interviewed on variables like family influence, educational background, occupational role models, and critical events for choosing a particular type of occupational career. The obtained results show that occupationally independent people reported stronger family ties, experienced fewer restrictions of formal education, and remembered fewer negative role models than the employed people. Implications of these results are discussed. PMID:11783553

    Holman, Eric W.

    To facilitate the testing of models for the evolution of languages, the present paper offers a set of linguistic features that are approximately independent of each other. To find these features, the adjusted Rand index (R‧) is used to estimate the degree of pairwise relationship among 130 linguistic features in a large published database. Many of the R‧ values prove to be near zero, as predicted for independent features, and a subset of 47 features is found with an average R‧ of -0.0001. These 47 features are recommended for use in statistical tests that require independent units of analysis.

    The present invention is a rapid sequence-independent amplification procedure (SIA). Even minute amounts of DNA from various sources can be amplified independent of any sequence requirements of the DNA or any a priori knowledge of any sequence characteristics of the DNA to be amplified. This method allows, for example the sequence independent amplification of microdissected chromosomal material and the reliable construction of high quality fluorescent in situ hybridization (FISH) probes from YACs or from other sources. These probes can be used to localize YACs on metaphase chromosomes but also--with high efficiency--in interphase nuclei.

    Urban areas are becoming increasingly important for wildlife as diminishing natural habitats no longer represent a suitable environment for many species. Red foxes (Vulpes vulpes) are nowadays common in many cities worldwide, and in recent years they have colonized urban areas in Estonia. We used a public web-based questionnaire approach to evaluate the distribution and behaviour of Estonian urban foxes, to detect related problems and to assess health risks to humans and domestic animals. In total, 1205 responses were collected throughout the country. Foxes have colonized the majority of Estonian towns (33 out of 47) in a relatively short period of time, and have already established breeding dens in several towns. Despite their recent arrival, the behaviour of Estonian urban foxes is similar to that reported in longer-established urban fox populations: they are mostly active during night-time, often visit city centres and some also have dens in such locations. Certain characteristics of urban foxes serve as a basis for conflict with humans: foxes have entered houses and attacked domestic animals, killing cats and poultry. About 8% of reported foxes exhibited symptoms of sarcoptic mange, a disease that also infects domestic animals, especially dogs. The proportion of mange-infected foxes was higher in large urban areas. In addition to mange, a substantial fraction of red foxes in Estonia are known to be infected with the life-threatening tapeworm Echinococcus multilocularis, the causative agent of alveolar echinococcosis. Therefore, urban foxes may represent a source of serious infectious disease for pets and humans. PMID:25531399

    Over the past 50 years, storminess has increased in northern Europe because of the changes in cyclonic activity. The cyclone season in the Baltic Sea area has shifted from autumn to winter; this has led to intensification of shore processes (erosion, sediment transport and accumulation) and has increased pressure to the economy (land use, coastal protection measures) of the coastal regions in the Baltic states. Therefore, studing the effects of such changes on shore processes in the past is critical for prediction of the future changes along the Baltic coasts. Beach ridge plains are found worldwide, where cyclones and storm surges affect accumulation forms. These sandy shores are highly susceptible to erosion. Due to the isostatic uplift on the NE coast of the Baltic Sea, the signs of major past events are well-preserved in the internal architecture of old coastal formations (dune ridge-swale complexes). Wave-eroded scarps in beach deposits are visible in subsurface ground-penetrating radar (GPR) records, indicating the past high-energy events. Several study areas and transects were selected on the NW coast of Estonia, using high-resolution topographic maps (LiDAR). Shore-normal subsurface surveys have been conducted with a digital GSSI SIR-3000 georadar with a 270 MHz antenna at each transect. Interpretation of GPR facies was based on hand auger and window sampler coring, which provided accurate depths of key stratigraphic boundaries and bounding surfaces. Several samples for luminescence and 14C dating were collected to determine the approximate chronology of the coastal formations along the Estonian coast. We have found that changes in storminess, including the periods of high and low intensity of storms in late Holocene, are clearly reflected in the internal patterns of ancient coastal formations. The sections with small ridges with short seaward-dipped layers (interface between wave-built and aeolian deposits) in deeper horizons are probably formed during

    This study examined the interrater reliability and validity of a newly developed test of physical work abilities, the Physical Work Performance Evaluation. Eleven physical therapists were trained to administer and score this evaluation. From this group, two therapists at a time simultaneously and independently evaluated 50 patients with musculoskeletal disorders as they performed the tasks of the Physical Work Performance Evaluation. At the conclusion of the evaluation, each therapist determined the safe level of physical work for each patient. A comparison of the two independent evaluations was used to determine reliability. To determine validity, the predicted level of work was compared with the actual level of work. Kappa coefficient between the two therapists on the level of work was .83. Spearman rho correlations between the predicted and actual levels of work ranged from .41 to .55. Only 14 to 18% were working above the level predicted by the Physical Work Performance Evaluation. These results indicate high interrater reliability. Given the lack of a perfect standard for validity comparisons, these results also provide evidence in support of convergent validity. The test can be used in making decisions regarding return to work after injury, preemployment placement, and vocational exploration. PMID:7823222

    2016-01-01

    We investigated an association between serum Growth Differentiation Factor 15 (GDF15) level and cardiovascular risk in patients with newly diagnosed type 2 diabetes mellitus (T2D). A total of 107 participants were screened for T2D and divided into a T2D group and a control group (without diabetes). We used the Framingham risk score (FRS) and the New Pooled Cohort Equation score to estimate the 10-year risk of atherosclerotic cardiovascular disease. Serum GDF15 levels were measured using an enzyme-linked immunosorbent assay. Correlation analyses were performed to evaluate the associations between GDF15 level and cardiovascular risk scores. The mean serum GDF15 level was elevated in the T2D group compared to the control group (P < 0.001). A positive correlation was evident between serum GDF15 level and age (r = 0.418, P = 0.001), the FRS (r = 0.457, P < 0.001), and the Pooled Cohort Equation score (r = 0.539, P < 0.001). After adjusting for age, LDL-C level, and body mass index (BMI), the serum GDF15 level was positively correlated with the FRS and the New Pooled Cohort Equation score. The serum GDF15 level is independently associated with cardiovascular risk scores of newly diagnosed T2D patients. This suggests that the level of GDF15 may be a useful predictive biomarker of cardiovascular risk in newly diagnosed T2D patients. PMID:27510384

    The field of chromatin biology has been advancing at an accelerated pace. Recent discoveries of previously uncharacterized sites and types of post-translational modifications (PTMs) and the identification of new sets of proteins responsible for the deposition, removal, and reading of these marks continue raising the complexity of an already exceedingly complicated biological phenomenon. In this Perspective article we examine the biological importance of new types and sites of histone PTMs and summarize the molecular mechanisms of chromatin engagement by newly discovered epigenetic readers. We also highlight the imperative role of structural insights in understanding PTM-reader interactions and discuss future directions to enhance the knowledge of PTM readout. PMID:27538025

    Abstract Observational studies on circulating fatty acid (FA) and primary prevention of hypertension have yielded inconsistent results, and the association among the Chinese population is not fully clear. The aim of the study was to discern important FAs that can discriminate hypertensive patients from normotensive persons, and investigate associations between the important FAs and risk of hypertension. We conducted a case-control study nested within a community-based cohort of 2447 Chinese participants aged 35 to 79 years who completed a baseline assessment between October 2012 and April 2013. In all, 480 patients with newly diagnosed hypertension were identified at baseline and 480 normotensive individuals were randomly selected as matched normotensive controls. Controls were individually matched to cases by age (±2 y), sex, and recruitment center, with a 1:1 case-to-control ratio. Serum FA profile was compared between cases and controls by orthogonal partial least squares-discriminant analyses. Odds ratio (OR) with 95% confidence interval (CI) for newly diagnosed hypertension was estimated by a conditional logistical analysis. After adjustment for body mass index, education, profession, family history of hypertension, salt intake, heart rate, blood lipids, and fasting glucose levels, serum FA profile in hypertensive patients was typically characterized by higher 16:0 and 16:1n-7, and lower 18:2n-6 and 22:6n-3, compared with normotensive controls. Docosahexaenoic acid (22:6n-3) and palmitoleic acid (16:1n-7) were identified as the important FA contributing most to the intergroup separations. When comparing the highest and lowest quartile of FA composition, newly diagnosed hypertension was negatively associated with 22:6n-3 (OR 0.65; 95% CI, 0.45–0.93; P for trend = 0.02), but positively associated with 16:1n-7 (OR 2.14; 95% CI, 1.46–3.12; P for trend < 0.001).

    The collapse of gas and oil prices in the mid-1980s significantly reduced the number of independent exploration companies. At the same time, a fundamental shift occurred among major oil companies as they allocated their exploration budgets toward international operations and made major production purchases. Several large independents also embraced a philosophy of budget supplementation through joint venture partnership arrangements. This has created a unique and unusual window of opportunity for the smaller independents (defined for this article as exploration and production companies with a market value of less than $1 billion) to access the extensive and high quality domestic prospect inventories of the major and large independent oil and gas companies and to participate in the search for large reserve targets on attractive joint venture terms. Participation in these types of joint ventures, in conjunction with internally generated plays selected through the use of today's advanced technology (computer-enhanced, high-resolution seismic; horizontal drilling; etc.) and increasing process for oil and natural gas, presents the domestic exploration-oriented independent with an attractive money-making opportunity for the 1990s.

    Background.  Studying the most extreme example of late diagnosis, new HIV diagnoses after death, may be instructive to HIV testing efforts. Using the results of routine HIV testing of autopsies performed by the Office of Chief Medical Examiner (OCME), we identified new HIV diagnoses after death in New York City (NYC) from 2008 to 2012. Methods.  Population-based registries for HIV and deaths were linked to identify decedents not known to be HIV-infected before death. Multivariable logistic regression models were constructed to determine correlates of a new HIV diagnosis after death among all persons newly diagnosed with HIV and among all HIV-infected decedents receiving an OCME autopsy. Results.  Of 264 893 deaths, 24 426 (9.2%) were autopsied by the NYC OCME. Of these, 1623 (6.6%) were infected with HIV, including 142 (8.8%) with a new HIV diagnosis at autopsy. This represents 0.8% (142 of 18 542) of all new HIV diagnoses during the 5-year period. Decedents newly diagnosed with HIV at OCME autopsy were predominantly male (73.9%), aged 13-64 years (85.9%), non-white (85.2%), unmarried (81.7%), less than college educated (83.8%), and residents of an impoverished neighborhood (62.0%). Of all HIV-infected OCME decedents aged ≥65 years (n = 71), 22.0% were diagnosed at autopsy. The strongest independent correlate of new HIV diagnosis at autopsy in both multivariable models was age ≥65 years. Conclusions.  Human immunodeficiency virus diagnoses first made after death are rare, but, when observed, these diagnoses are more commonly found among persons ≥65 years, suggesting that despite highly visible efforts to promote HIV testing community-wide, timely diagnosis among older adults living in impoverished, high-prevalence neighborhoods may require additional strategies.

    2011-12-01

    Upon initiating replication of the Caulobacter chromosome, one copy of the parS centromere remains at the stalked pole; the other moves to the distal pole. We identified the segregation dynamics and compaction characteristics of newly replicated Caulobacter DNA during transport (highly variable from cell to cell) using time-lapse fluorescence microscopy. The parS centromere and a length (also highly variable) of parS proximal DNA on each arm of the chromosome are segregated with the same relatively slow transport pattern as the parS locus. Newly replicated DNA further than about 100 kb from parS segregates with a different and faster pattern, while loci at 48 kb from parS segregate with the slow pattern in some cells and the fast pattern in others. The observed parS-proximal DNA compaction characteristics have scaling properties that suggest the DNA is branched. HU2-deletion strains exhibited a reduced compaction phenotype except near the parS site where only the ΔHU1ΔHU2 double mutant had a compaction phenotype. The chromosome shows speed-dependent extension during translocation suggesting the DNA polymer is under tension. While DNA segregation is highly reliable and succeeds in virtually all wild-type cells, the high degree of cell to cell variation in the segregation process is noteworthy.

    Consistency limits are one of the most prominent parameters to be determined in geotechnical investigations. While these limits are akin to one another, different tools determine each one. Each method of determining consistency limits has its own uncertainties, the operator dependency being the top source of uncertainty. Liquid limit (LL) and plastic limit (PL) tests have a number of uncertainties affecting the test results. The very speculative nature of the bead-rolling method for the plastic limit has long been known. Besides this, its results can be barely accepted as quantitative. In the past, a number of attempts have been made to eliminate these setbacks for Atterberg limits. The scope of this investigation is to evaluate the potential of newly developed "mud press method (MPM)" to predict the two consistency limits. The material employed for this investigation covers 275 soils, whose liquid limits range from 28 to 166. The log(a) and 1/b parameters obtained from the MPM method were correlated to results of the conventional methods. The PL and LL for each soil were predicted using empirical forms and were compared with the laboratory values. Remarkably good matches were obtained between the conventionally determined test results and the predicted values for the liquid and plastic limits. The newly developed tool is superior in several aspects to the available conventional methods and tools.

    2010-01-01

    Primary central nervous system lymphoma (PCNSL) accounts for only 3% of brain tumors. It can involve the brain parenchyma, leptomeninges, eyes and the spinal cord. Unlike systemic lymphoma, durable remissions remain uncommon. Although phase III trials in this rare disease are difficult to perform, many phase II trials have attempted to define standards of care. Treatment modalities for patients with newly diagnosed PCNSL include radiation and/or chemotherapy. While the role of radiation therapy for initial management of PCNSL is controversial, clinical trials will attempt to improve the therapeutic index of this modality. Routes of chemotherapy administration include intravenous, intraocular, intraventricular or intra-arterial. Multiple trials have outlined different methotrexate-based chemotherapy regimens and have used local techniques to improve drug delivery. A major challenge in the management of patients with PCNSL remains the delivery of aggressive treatment with preservation of neurocognitive function. Because PCNSL is rare, it is important to perform multicenter clinical trials and to incorporate detailed measurements of long-term toxicities. In this review we focus on different chemotherapeutic approaches for immunocompetent patients with newly diagnosed PCNSL and discuss the role of local drug delivery in addition to systemic therapy. We also address the neurocognitive toxicity of treatment. PMID:21789140

  11. HOW CAN NEWLY BORN RAPIDLY ROTATING NEUTRON STARS BECOME MAGNETARS?

    SciTech Connect

    Cheng, Quan; Yu, Yun-Wei

    2014-05-10

    In a newly born (high-temperature and Keplerian rotating) neutron star, r-mode instability can lead to stellar differential rotation, which winds the seed poloidal magnetic field (∼10{sup 11} G) to generate an ultra-high (∼10{sup 17} G) toroidal field component. Subsequently, by succumbing to the Tayler instability, the toroidal field could be partially transformed into a new poloidal field. Through such dynamo processes, the newly born neutron star with sufficiently rapid rotation could become a magnetar on a timescale of ∼10{sup 2} {sup –} {sup 3} s, with a surface dipolar magnetic field of ∼10{sup 15} G. Accompanying the field amplification, the star could spin down to a period of ∼5 ms through gravitational wave radiation due to the r-mode instability and, in particular, the non-axisymmetric stellar deformation caused by the toroidal field. This scenario provides a possible explanation for why the remnant neutron stars formed in gamma-ray bursts and superluminous supernovae could be millisecond magnetars.

    Independent bilateral primary bronchial carcinomas are not common. Since Beyreuther's description in 1924, 16 well-documented cases of independent primary bronchial carcinomas of different histology have been described. From 1965 to 1970, eight cases were seen at the London Chest Hospital. In order to make the diagnosis of a second primary bronchial carcinoma, each tumour should be malignant and neither should be a metastasis from the other. To meet this last criterion, the histopathological features of the two tumours must be different. Many cases have been described in the literature as double primary bronchial carcinomas where the second primary had the same histological features as the first. Images PMID:4327711

    The Bonneville Power Administration (BPA) contracted with the Pacific Northwest National Laboratory (PNNL) to provide technical analytical support for system-wide fish passage information (BPA Project No. 2006-010-00). The goal of this project was to produce rigorous technical analysis products using independent analysts and anonymous peer reviewers. In the past, regional parties have interacted with a single entity, the Fish Passage Center to access the data, analyses, and coordination related to fish passage. This project provided an independent technical source for non-routine fish passage analyses while allowing routine support functions to be performed by other well-qualified entities.

    1989-01-01

    An evaluation of the newly formulated Dow Corning 321 dry film lubricant was performed. The purpose of the evaluation was to compare lubricating characteristics of Dow Corning 321 (STW4-2955, SCN No. 3) to those of Molykote 321R (STW4-2955). Ten igniter bolts were installed and torqued on test plates using the old formulation thread lubricant (Molykote 321R), and 10 bolts were installed using the new formulation (Dow Corning 321). After bolt removal, no signs of galling were found on any of the bolts or test plates threaded holes. Average torque-load values for each formulation were very close. Test results showed there are no significant differences in lubrication abilities between Molykote 321R and Dow Corning 321. It is recommended that, once current supplies of Molykote 321R are depleted, Dow Corning 321 dry film lubricant be used in place of Molykote 321R as a thread lubricant on redesigned solid rocket motor assemblies.

    2011-03-01

    Laboratory experiments were conducted to investigate tolerance and physiological responses of Galaxias'nebula', a newly discovered and widespread African galaxiid, to aerial exposure. This species can tolerate emersion for at least 36 h. Changes in water level and dewatering did not induce the fish to burrow into the substratum or find refugia, nor was there detectable mucus production following aerial exposure. Opercular movement, a proxy for gill ventilation rate, however, did vary with changes in water level. The initial steady ventilation rate increased significantly when the fish were partially emersed and ventilation ceased immediately upon total air exposure. When fish were re-immersed, there was first a period of hyperactivity with a corresponding inflated gill ventilation rate which was restored to pretreatment levels within 2 h. This is the first documented case of amphibious capabilities in an African galaxiid, which has implications for the interpretation of its widespread distribution pattern.

    A series of pyrazolopyridine and pyridopyrimidine derivatives 2-6 were newly synthesized using 3,5-bisarylmethylene-1-methylpiperidone as the starting material. The anticancer activities of the synthesized compounds were evaluated using 59 different human tumor cell lines, representing cancers of CNS, ovary, renal, breast, colon, lung, leukemia, and melanoma, prostate as well as kidney. Some of the tested compounds, especially those with a fluorine substituent at the para-position in the phenyl ring and those with a pyridopyrimidine-2-thione with a free -NH or -SH, exhibited greater in vitro anti-tumor activities at low concentrations (log 10 [GI₅₀] = -4.6) against the human tumor cell lines. Additionally, some of the compounds had moderate inhibitory effects on the growth of the cancer cell lines. The detailed synthesis, spectroscopic data and antitumor properties of the synthesized compounds are reported.

  5. Newly hatched chicks solve the visual binding problem.

    PubMed

    2014-07-01

    For an organism to perceive coherent and unified objects, its visual system must bind color and shape features into integrated color-shape representations in memory. However, the origins of this ability have not yet been established. To examine whether newborns can build an integrated representation of the first object they see, I raised newly hatched chicks (Gallus gallus) in controlled-rearing chambers that contained a single virtual object. This object rotated continuously, revealing a different color and shape combination on each of its two faces. Chicks were able to build an integrated representation of this object. For example, they reliably distinguished an object defined by a purple circle and yellow triangle from an object defined by a purple triangle and yellow circle. This result shows that newborns can begin binding color and shape features into integrated representations at the onset of their experience with visual objects. PMID:24840718

    Ocular manifestations of lymphoma are described in humans and dogs but rarely in cats. In this prospective study, cats with newly diagnosed and treatment-naïve lymphoma were evaluated concerning clinical stage and ophthalmologic findings. Twenty-six cats were included. In 12 cats (48%), ocular changes were documented. Uveitis anterior and posterior were predominant findings, being present in 58% of affected individuals. Other findings included exophthalmos, corneal surface lesions and chemosis. Eight cats received chemotherapy, two of which had ocular involvement. In these two cats, a complete remission of an anterior and a partial remission of a posterior uveitis were documented. Due to the detection of ocular involvement, a stage migration from stage IV to V occurred in four patients. In the light of these findings, an opthalmological examination may be considered as an important part of staging in feline lymphoma as well as of follow-up examination in affected cats.

    2015-01-01

    The newly born millisecond pulsars are investigated as possible energy sources for creating ultra-high energy electrons. The transfer of energy from the star rotation to high energy electrons takes place through the Landau damping of centrifugally driven (via a two stream instability) electrostatic Langmuir waves. Generated in the bulk magnetosphere plasma, such waves grow to high amplitudes, and then damp, very effectively, on relativistic electrons driving them to even higher energies. We show that the rate of transfer of energy is so efficient that no energy losses might affect the mechanism of particle acceleration; the electrons might achieve energies of the order of 10(18) eV for parameters characteristic of a young star.

    Radiation induced grafting (RIG) is acquired to prepare a number of adsorbents for newly emerging environmental applications using a single route involving RIG of glycidymethacrylate (GMA) onto polyethylene-polypropylene (PE-PP) non-woven fabric. The grafted fabric was subjected to one of three functionalization reactions to impart desired ionic characters. This included treatment with (1) N-dimethyl-D-glucamine, (2) triethylamine and (3) triethylamine and alkalisation with KOH. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM) were used to study the changes in chemical and physical structures of the obtained fibrous adsorbents. The potential applications of the three adsorbents for removal of boron from solutions, capturing CO2 from CO2/N2 mixtures and catalysing transesterification of triacetin/methanol to methyl acetate (biodiesel) were explored. The obtained fibrous adsorbents provide potential alternatives to granular resins for the investigated applications and require further development.

    Bacillary angiomatosis (also called epithelioid angiomatosis) is a newly recognized disease most often characterized by a cutaneous infection with reddish papules of vascular origin. It is caused by a weakly reactive gram-negative bacillus, which can be easily demonstrated in tissue sections with the Warthin-Starry stain. Bacillary angiomatosis usually responds readily to treatment with oral erythromycin, 250 to 500 mg, taken four times a day for 2 weeks to 1 month. Because the skin is the most common site of involvement, it is important that the dermatologist recognize this unusual condition. It is essential that treatment be started as soon as possible because deaths may result from visceral and mucosal involvement. The clinical, histologic, and microbiologic aspects of bacillary angiomatosis are discussed and depicted in detail and speculations regarding the pathogenesis are rendered.

    Idiopathic anaphylaxis (IA) is a life-threatening allergic disease and the most common diagnosis given to patients following an anaphylactic event. The inability of the healthcare provider and the patient to identify the trigger for anaphylaxis makes standard allergen avoidance measures ineffectual. IA is diagnosed after other causes of anaphylaxis have been excluded. Mast cell activation syndromes (MCAS), mastocytosis, IgE to galactose-alpha-1,3-galactose (α-gal), and certain medications have recently been recognized as causes of anaphylaxis that were previously labeled idiopathic. This review will describe the epidemiology and proposed theories of pathogenesis for IA, its diagnostic approach, its clinical management, and examine newly recognized disorders that were previously labeled as idiopathic anaphylaxis.

    Scent-marking was studied in wolves (Canis lupus) along 133 km of tracks in northern Minnesota during winters of 1975 to 1976 and 1976 to 1977 and in two captive packs and four captive pairs for various periods. Lone wolves, which possess neither mates nor territories, rarely marked by raised-leg urination and defaecated and urinated less along roads and trails, where territorial pairs and packs generally marked. Newly formed pairs marked the most, eventually decreasing their rates to those of established packs. Generally, wolves that scent-marked also bred, whereas non-marking wolves usually did not breed. Scent-marking apparently is important to the success of courtship in new pairs and to reproductive synchrony in established pairs, as well as serving a territorial function.

    Metabolically microorganisms are diverse, and they are capable of transforming almost every known group of chemical compounds present in coal and oil in various forms. In this milieu, one of the important microbial metabolic processes is the biodesulfurization [cleavage of carbon-sulfur (C-S) bond] of thiophenic compounds, such as dibenzothiophene (DBT), which is the most abundant form of organic sulfur present in fossil fuels. In the current study, ten newly isolated bacterial isolates, designated as species of genera Gordonia, Amycolatopsis, Microbacterium and Mycobacterium, were enriched from different samples in the presence of DBT as a sole source of organic sulfur. The HPLC analysis of the DBT grown cultures indicated the consumption of DBT and accumulation of 2-hydroxybiphenyl (2-HBP). Detection of 2-HBP, a marker metabolite of 4S (sulfoxide-sulfone-sulfinate-sulfate) pathway, suggested that the newly isolated strains harbored metabolic activity for DBT desulfurization through the cleavage of C-S bond. The maximum 2-HBP formation rate was 3.5 µmol/g dry cell weight (DCW)/h. The phylogenetic analysis of the new isolates showed that they had diverse distribution within the phylogenetic tree and formed distinct clusters, suggesting that they might represent strains of already reported species or they were altogether new species. Estimates of evolutionary divergence showed high level of nucleotide divergence between the isolates within the same genus. The new isolates were able to use a range of heterocyclic sulfur compounds, thus making them suitable candidates for a robust biodesulfurization system for fossil fuels. PMID:26973057

    The current study set to examine the effects of simulator use in driving instruction on newly licensed drivers, comparing the road safety knowledge and reported intended behavior, as well as the actual driving performance of new drivers. Participants consisted of 280 newly licensed driver, of which 140 whose drivers license training included additional simulator-based lessons, and 140 drivers whose training precluded simulator-based lessons. All drivers answered questionnaires pertaining to their intended safe driving behaviors (according to Ajzen's (2000) theory of planned behavior), and to their traffic safety knowledge. Of the initial sample, 40 drivers received actual driving performance evaluation by an expert driving instructor, as well as by in-vehicle data recorders (IVDRs). We assumed that safer drivers report safer driving intentions, demonstrate greater traffic safety knowledge, evaluated as safer drivers by the driving instructor, and display lower and stable driving parameters on the IVDRs. We hypothesized that theoretical driving studies combined with practical training on simulators will elevate the safety level of novices driving. Hierarchical regression analyses on driving intentions indicated that drivers who did not receive simulator-based lessons demonstrated safer driving intentions compared to drivers who received simulator-based lessons. This pattern possibly indicating the drivers who received simulator-based lessons felt more confident in their driving abilities compared to drivers who did not receive simulated training. No significant difference was found in traffic safety knowledge, or in the evaluation of the expert driving instructor. IDVR data comparisons indicated drivers who received simulator-based lessons braked more often and were less prone to headway events, suggesting a more responsive driving style. These findings do not point to any significant advantage or disadvantage of the current simulator-based driving training over

    Presence of circulating tumor cells (CTC) is associated with poor prognosis in patients with metastatic colorectal cancer (CRC). The present study was conducted to determine if the presence of CTC prior to surgery and during follow‑up in patients with newly diagnosed non-metastatic CRC can identify patients at risk for disease recurrence. In a prospective single center study 183 patients with newly diagnosed non-disseminated CRC, scheduled for surgery, were enrolled and followed-up for a median of 5.1 years. CTC were enumerated with the CellSearch system in 4 aliquots of 7.5 ml of blood before surgery and at several time-points during follow-up after surgery. The results showed that ≥1 CTC/30 ml of blood were detected in 44 (24%) patients before surgery. Patients with CTC before surgery had a significant decrease in recurrence-free survival (RFS, log-rank test p=0.014) and colon cancer related survival (CCRS, p=0.002). The 5-year RFS dropped from 75 to 61% and the 5-year CCRS from 83 to 69% for patients with CTC before surgery. The presence of CTC and positive lymph nodes remained significant factors in multivariate analysis for recurrence-free survival (RFS). Surprisingly, the presence of CTC weeks after surgery was not significantly associated with RFS and CCRD whereas CTC 2-3 years after surgery was again significantly associated with RFS and CCRD. The presence of CTC in patients with stage I-III CRC before surgery is associated with a significant reduction in RFS and CCRS. These findings suggest a role of CTC detection to assess which patients need adjuvant treatment.

    The sensorimotor system (SMS) plays an important role in sports and in every day movement. Several tools for assessment and training have been designed. Many of them are directed to specific populations, and have major shortcomings due to the training effect or safety. The aim of the present study was to design and assess a dynamic sensorimotor test and training device that can be adjusted for all levels of performance. The novel pneumatic-driven mechatronic device can guide the trainee, allow independent movements or disrupt the individual with unpredicted perturbations while standing on a platform. The test-reliability was evaluated using intraclass correlation coefficient (ICC). Subjects were required to balance their center of pressure (COP) in a target circle (TITC). The time in TITC and the COP error (COPe) were recorded for analysis. The results of 22 males and 14 females (23.7 ± 2.6 years) showed good to excellent test-retest reliability. The newly designed Active Balance System (ABS) was then compared with the Biodex Balance System SD® (BBS). The results of 15 females, 14 males (23.4 ± 1.6 years) showed modest correlation in static and acceptable correlation in dynamic conditions, suggesting that ABS could be a reliable and comparable tool for dynamic balance assessments.

    The functionality of a newly developed silicone oil-free (SOF) syringe system, of which the plunger stopper is coated by a novel coating technology (i-coating™), was assessed. By scanning electron microscopy observations and other analysis, it was confirmed that the plunger stopper surface was uniformly covered with the designed chemical composition. A microflow imaging analysis showed that the SOF system drastically reduced both silicone oil (SO) doplets and oil-induced aggregations in a model protein formulation, whereas a large number of subvisible particles and protein aggregations were formed when a SO system was used. Satisfactory container closure integrity (CCI) was confirmed by means of dye and microorganism penetration studies. Furthermore, no significant difference between the break loose and gliding forces was observed in the former, and stability studies revealed that the SOF system could perfectly show the aging independence in break loose force observed in the SO system. The results suggest that the introduced novel SOF system has a great potential and represents an alternative that can achieve very low subvisible particles, secure CCI, and the absence of a break loose force. In particular, no risk of SO-induced aggregation can bring additional value in the highly sensitive biotech drug market. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci 103:1520–1528, 2014 PMID:24643749

    We present a search for γ-ray emission from the direction of the newly discovered dwarf galaxy Reticulum II. Using Fermi-LAT Collaboration data, we detect a signal that exceeds expected backgrounds between ∼2-10  GeV and is consistent with annihilation of dark matter for particle masses less than a few ×10^{2}  GeV. Modeling the background as a Poisson process based on Fermi-LAT diffuse models, and taking into account trial factors, we detect emission with p value less than 9.8×10^{-5} (>3.7σ). An alternative, model-independent treatment of the background reduces the significance, raising the p value to 9.7×10^{-3} (2.3σ). Even in this case, however, Reticulum II has the most significant γ-ray signal of any known dwarf galaxy. If Reticulum II has a dark-matter halo that is similar to those inferred for other nearby dwarfs, the signal is consistent with the s-wave relic abundance cross section for annihilation.

    Botezomib-based induction is highly effective for the treatment of newly diagnosed multiple myeloma (NDMM). We investigated the outcomes of NDMM patients who failed to respond to bortezomib-based induction in a 'real-life' clinical setting. In a cohort of 295 consecutive NDMM patients in 3 medical centers, 74 (25%) failed to achieve at least partial response after 4 induction cycles, and were classified as non-responsive. Compared to induction responders, they were older, more frequently anemic, had a higher incidence of del17p and ISS-3, and a worse performance status. In multivariable analysis, bortezomib-based induction failure occurred in 25% of patients and was the strongest independent factor predicting mortality with a 5-fold hazard ratio (95% CI 1.44-8.68). Three-year overall survival in responsive vs. non-responsive patients were 76% vs. 53%, respectively (p < 0.0001). Survival from time of salvage second-line treatment was significantly shorter among induction non-responders vs. responders (25 months vs. not-reached, p = 0.024). PMID:26727104

    The functionality of a newly developed silicone oil-free (SOF) syringe system, of which the plunger stopper is coated by a novel coating technology (i-coating™), was assessed. By scanning electron microscopy observations and other analysis, it was confirmed that the plunger stopper surface was uniformly covered with the designed chemical composition. A microflow imaging analysis showed that the SOF system drastically reduced both silicone oil (SO) doplets and oil-induced aggregations in a model protein formulation, whereas a large number of subvisible particles and protein aggregations were formed when a SO system was used. Satisfactory container closure integrity (CCI) was confirmed by means of dye and microorganism penetration studies. Furthermore, no significant difference between the break loose and gliding forces was observed in the former, and stability studies revealed that the SOF system could perfectly show the aging independence in break loose force observed in the SO system. The results suggest that the introduced novel SOF system has a great potential and represents an alternative that can achieve very low subvisible particles, secure CCI, and the absence of a break loose force. In particular, no risk of SO-induced aggregation can bring additional value in the highly sensitive biotech drug market. PMID:24643749

    γ-poly glutamic acid (γ-PGA) has received considerable attention for pharmaceutical and biomedical applications. γ-PGA from the newly isolate Bacillus licheniformis NRC20 was purified and characterized using diffusion distance agar plate, mass spectrometry and thin layer chromatography. All analysis indicated that γ-PGA is a homopolymer composed of glutamic acid. Its molecular weight was determined to be 1266 kDa. It was composed of L- and D-glutamic acid residues. An amplicon of 3050 represents the γ-PGA-coding genes was obtained, sequenced and submitted in genbank database. Its amino acid sequence showed high similarity with that obtained from B. licheniformis strains. The bacterium NRC 20 was independent of L-glutamic acid but the polymer production enhanced when cultivated in medium containing L-glutamic acid as the sole nitrogen source. Finally we can conclude that γ-PGA production from B. licheniformis NRC20 has many promised applications in medicine, industry and nanotechnology.

    Aims/hypothesis The role of increased gluconeogenesis as an important contributor to fasting hyperglycaemia at diabetes onset is not known. We evaluated the contribution of gluconeogenesis and glycogenolysis to fasting hyperglycaemia in newly diagnosed youths with type 2 diabetes following an overnight fast. Methods Basal rates (μmol kgFFM−1 min−1) of gluconeogenesis (2H20), glycogenolysis and glycerol production ([2H5] glycerol) were measured in 18 adolescents (nine treatment naive diabetic and nine normal-glucose-tolerant obese adolescents). Results Type 2 diabetes was associated with higher gluconeogenesis (9.2±0.6 vs 7.0±0.3 μmol kgFFM−1 min−1, p < 0.01), plasma fasting glucose (7.0±0.6 vs 5.0±0.2 mmol/l, p = 0.004) and insulin (300±30 vs 126±31 pmol/l, p = 0.001). Glucose production and glycogenolysis were similar between the groups (15.4±0.3 vs 12.4±1.4 μmol kgFFM−1 min−1, p = 0.06; and 6.2±0.8 vs 5.3±0.7 μmol kgFFM−1 min−1, p = 0.5, respectively). After controlling for differences in adiposity, gluconeogenesis, glycogenolysis and glucose production were higher in diabetic youth (p ≤ 0.02). Glycerol concentration (84±6 vs 57±6 μmol/l, p = 0.01) and glycerol production (5.0±0.3 vs 3.6±0.5 μmol kgFFM−1 min−1, p =0.03) were 40% higher in youth with diabetes. The increased glycerol production could account for only ~1/3 of substrate needed for the increased gluconeogenesis in diabetic youth. Conclusion/interpretations Increased gluconeogenesis was a major contributor to fasting hyperglycaemia and hepatic insulin resistance in newly diagnosed untreated adolescents and was an early pathological feature of type 2 diabetes. Increased glycerol availability may represent a significant source of new carbon substrates for increased gluconeogenesis but would not account for all the carbons required to sustain the increased rates.

    This study investigated newly qualified teachers' visions of science learning and teaching. The study also documented their preparation in an elementary science methods course. The research questions were: What educational and professional experiences influenced the instructor's visions of science learning and teaching? What visions of science learning and teaching were promoted in the participants' science methods course? What visions of science learning and teaching did these newly qualified teachers bring with them as they graduated from their teacher preparation program? How did these visions compare with those advocated by reform documents? Data sources included participants' assignments, weekly reflections, and multi-media portfolio finals. Semi-structured interviews provided the emic voice of participants, after graduation but before they had begun to teach. These data were interpreted via a combination of qualitative methodologies. Vignettes described class activities. Assertions supported by excerpts from participants' writings emerged from repeated review of their assignments. A case study of a typical participant characterized weekly reflections and final multi-media portfolio. Four strands of science proficiency articulated in a national reform document provided a framework for interpreting activities, assignments, and interview responses. Prior experiences that influenced design of the methods course included an inquiry-based undergraduate physics course, participation in a reform-based teacher preparation program, undergraduate and graduate inquiry-based science teaching methods courses, participation in a teacher research group, continued connection to the university as a beginning teacher, teaching in diverse Title 1 schools, service as the county and state elementary science specialist, participation in the Carnegie Academy for the Scholarship of Teaching and Learning, service on a National Research Council committee, and experience teaching a

    Objectives Diabetic ketoacidosis (DKA) is the leading cause of morbidity and mortality in children with type 1 diabetes mellitus (TIDM). Many patients with newly diagnosed type 1 diabetes present with DKA. The aim of this study is to determine the frequency and the clinical presentation of diabetic ketoacidosis at the diagnosis of type 1 diabetes mellitus in youths in hamadan, Western Province of Iran. Methods The Clinical and laboratory data of a total of 200 patients under 19 years of age with newly diagnosed type 1 diabetes mellitus between 1995-2005 were retrospectively reviewed. Statistical analysis was performed using SPSS 11. Results 48 (24%)of the children were presented in a state of ketoacidosis. Sever form of DKA (pH≤7.2) was observed in 54.5% of patients. The mean age at diagnosis was 7.3±5.15 years in DKA group and 8.59±3.07 in non-DKA group (p=0.22). 60.4% of patient with DKA were female whereas in the non-DKA group, 53.3% of patients were female, the difference was not significant (p=0.38). The duration of symptoms before diagnosis was 14.84±8.19 days in patients with DKA and 22.39±2.27 in the non-DKA group, (p=0.11). No significant difference was found between the age, sex and duration of the symptoms and occurance of DKA. Polydipsia (85.4) polyuria (83.3%), weakness (68.8%) and abdominal pain (52.1%) were the most frequently notified symptoms among the patients. In two cases, diagnosis of DKA was preceded by as appendicitis and the patient underwent appendectomy. Conclusion Frequency of DKA at onset of type 1 diabetes mellitus was significant in the studied region. However, it was lower than other regions in Asia. Polydipsia, polyuria, fatigue and abdominal pain were the most common symptoms on presentation. PMID:22125712

    We introduce a growing network model which generates both modular and hierarchical structure in a self-organized way. To this end, we modify the Barabási-Albert model into the one evolving under the principles of division and independence as well as growth and preferential attachment (PA). A newly added vertex chooses one of the modules composed of existing vertices, and attaches edges to vertices belonging to that module following the PA rule. When the module size reaches a proper size, the module is divided into two, and a new module is created. The karate club network studied by Zachary is a simple version of the current model. We find that the model can reproduce both modular and hierarchical properties, characterized by the hierarchical clustering function of a vertex with degree k, C(k), being in good agreement with empirical measurements for real-world networks.

    The investigation was carried out in 8-year-old Scots pine (Pinus sylvestris L.) and lodgepole pine (Pinus contorta var. latifolia Engelm.) plantations on post-mining area, Northeast Estonia. The aim of the study was to assess the suitability of lodgepole pine for restoration of degraded lands by comparing the growth, biomass, and nutrient concentration of studied species. The height growth of trees was greater in the Scots pine stand, but the tree aboveground biomass was slightly larger in the lodgepole pine stand. The aboveground biomass allocation to the compartments did not differ significantly between species. The vertical distribution of compartments showed that 43.2% of the Scots pine needles were located in the middle layer of the crown, while 58.5% of the lodgepole pine needles were in the lowest layer of the crown. The largest share of the shoots and stem of both species was allocated to the lowest layer of the crown. For both species, the highest NPK concentrations were found in the needles and the lowest in the stems. On the basis of the present study results, it can be concluded that the early growth of Scots pine and lodgepole pine on oil shale post-mining landscapes is similar. PMID:21374054

    OBJECTIVE: To study the cultural differences in moral disengagement, which lends support to attitudes used to justify violence. METHODS: We carried out classroom surveys of a total of 3122 students in the USA (Houston, TX, and Washington, DC) and in four European countries--Estonia (Tartu), Finland (Helsinki), Romania (Satu Mare) and the Russian Federation (St Petersburg). Data were also taken from a random sample telephone survey of 341 young adults (aged 18-35 years) in Texas, USA. Ten distinct groups were studied. Seven questions were common to all the surveys, using identical statements about the participants' agreement with attitudes relating to war, diplomacy, killing, and the punishment of children. FINDINGS: The US students were more likely than those in Europe to agree with the following statements: "War is necessary" (20% vs 9%), "A person has the right to kill to defend property" (54% vs 17%), and "Physical punishment is necessary for children" (27% vs 10%). Justification of war and killing was less common among females than males in all groups; other differences within the US groups and the European groups were smaller than the differences between the US and European groups. CONCLUSION: The results confirm the gap between the US and European groups in moral disengagement attitudes and tendencies that could lead to deadly violence. PMID:11417032

    Diabetes has reached pandemic proportions worldwide. To address and assist health care professionals in maintaining and updating their knowledge base on diabetes care, a multilateral project within the framework of the Lifelong Learning Programme and the Erasmus Curriculum Development - sub programme was initiated in 2008. Four European countries are involved in the project - Estonia, Finland, Ireland and Lithuania. Across all four countries the prevalence of diabetes is rising rapidly. The project's (DIPRA - Counselling for Practice - a pilot of improving counselling quality of diabetes) main product will be an on-line study module on patient education and counselling for health care professionals. The management of diabetes demands a broad range of skills which include, communication, leadership, counselling, teaching and research to name but a few. While it is acknowledged that nurses can incorporate these skills into practice and so benefit the care of the patient there is no uniformity across the four countries studied as to what constitutes a specialist diabetes nurse. The study module and all the materials (databank, on-line lectures, and interactive exercises) will be developed in English and translated into partners' national languages (Estonian, Finnish, Lithuanian) to maximize the accessibility of all professionals in partner countries.

    The water balance of wetlands plays an integral role in their function. Developments adjacent to wetlands can affect their water balance through impacts on groundwater flow and increased discharge in the area, and they can cause lowering of the wetland water table. A 430 km2 area was selected for groundwater modelling to asses the effect of underground mining on the water balance of wetlands in north-eastern Estonia. A nature conservation area (encompassing Selisoo bog) is within 3 km of an underground oil-shale mine. Two future mining scenarios with different areal extents of mining were modeled and compared to the present situation. Results show that the vertical hydraulic conductivity of the subsurface is of critical importance to potential wetland dewatering as a result of mining. Significant impact on the Selisoo bog water balance will be caused by the approaching mine but there will be only minor additional impacts from mining directly below the bog. The major impact will arise before that stage, when the underground mine extension reaches the border of the nature conservation area; since the restriction of activities in this area relates to the ground surface, the conservation area’s border is not sufficiently protective in relation to underground development.

    The present work reports the synthesis of a new series of pyridopyrimidine derivatives. The newly synthesized compounds were characterized by various analytical and spectral techniques. In addition, their antimicrobial activity was evaluated as well as modeling studies were performed to investigate their ability to recognize and bind to the biotin carboxylase (BC)-active site. The results showed a broad spectrum antibacterial and antifungal profile of the synthesized derivatives. Docking results demonstrated that all members of this class of new derivatives were able to recognize the active site of Escherichia coli BC and form different types of bonding interactions with key active site amino acid residues. Besides the compounds with promising antimicrobial activity in addition to 6-aminothiouracil, as control, were incorporated into polycaprolactone nanoparticles to improve their water solubility, permeability through physiological barriers and consequently enhanced therapeutic efficacy. The compounds-loaded nanoparticles were prepared using single emulsion-solvent evaporation technique, and their diameters were found to be in the range 136 ± 30 to 213 ± 28 nm. Transmission electron microscopy (TEM) showed a spherical and dense morphology of the nanoparticles. The results also showed high entrapment efficiency of the synthesized bioactive compounds in the nanoparticles (85 ± 5% to 91 ± 2%) with a desirable in vitro biodegradation and release profiles.

    Newly arisen adaptive alleles such as insecticide resistance genes represent a good opportunity to investigate the theories put forth to explain the molecular basis of dominance and its possible evolution. Dominance levels of insecticide resistance conferred by insensitive alleles of the acetylcholinesterase gene were analyzed in five resistant strains of the mosquito Culex pipiens. Dominance levels were found to differ between strains, varying from partial recessivity to complete dominance. This variation was not explained by differences in catalytic properties of the enzyme, since four of the five resistant strains had identical inhibition properties for the insensitive acetylcholinesterase. Among these four laboratory strains and in individuals collected from natural populations, we found a correlation between increased acetylcholinesterase activities and higher dominance levels. We propose a molecular explanation for how variation in acetylcholinesterase activity may result in variation of dominance level. We also conjecture that the four resistant strains did not differ in their amino acid sequence in the catalytically active regions of acetylcholinesterase, but that the expression of the gene was regulated by either neighboring or distant sites, thereby modifying the dominance level. Under this interpretation, dominance levels may evolve in this system, since heritable variation in acetylcholinesterase activity was found.

    Many newly arrived international adoptees (IA) have difficulties with eating, sleeping, and self-soothing/self-stimulating (SS) behaviors. However, to date the prevalence of these problems and associated risk factors have not been clearly identified. Therefore, we proposed to evaluate 387 IA for the presence of these self-regulation and behavioral difficulties, and examined the relationships between these behaviors and pre-adoptive risk factors including growth measures, orphanage care, age at arrival and presence of medical complications. Data on participants were collected in a retrospective chart review and entered into a standardized data collection sheet by a trained research assistant. This exploratory study included 133 M and 254 F with an average age (M = 16) months at the time of the study. Children in the study represented adoptees from seventeen countries. Forty-nine per cent (49%) of the retrospective sample exhibited SS behaviors, 48% had sleep disturbances, and 34% had eating issues. Many had difficulties in more than one area. Country of origin, pre-adoption residence, and arrival nutritional status all related to the presence of these problems. Hence, self-regulation difficulties are common but both the course and influence of those behaviors on family functioning remains unknown.

    We identified patients with newly diagnosed rheumatoid arthritis (RA) in the ages 18-65 years who needed psychosocial interventions. A total of 123 patients (90 women) were asked to participate, but 19 declined and 4 dropped out early in the study, leaving a total of 100 patients (75 women) in the sample. Questionnaires used were the Epidemiological Investigation on Rheumatoid Arthritis study questionnaire, the Hospital Anxiety and Depression Scale, the Sense of Coherence (SOC) scale, and the General Coping Questionnaire. Interviews showed that 46% of the included 100 patients had psychosocial problems (PSP). One third of them had problems directly related to RA. The rest had problems with their life situation in general, without or reinforced by RA. Compared to patients without psychosocial problems, PSP patients lived in more strained social situations, especially regarding personal finances and social support. More of the PSP patients were anxious, showed lower SOC scores, and also used more emotion-based coping strategies (resignation, protest, isolation and intrusion) and less problem-oriented (minimization). They also had higher scores on depression and more frequently expected that RA would negatively affect their future. PSP patients also experienced a more negative impact of the disease, a finding not confirmed by the sickness activity score judged by the rheumatologist. Thus, early in the course of RA, screening instruments should be used to identify PSP patients. Psychosocial treatment and support by medical social workers skilled in RA care should be offered.

    Savings, or faster relearning after initial learning, demonstrates humans' remarkable ability to retain learned movements amid changing environments. This is important within the context of locomotion, as the ability of the nervous system to "remember" how to walk in specific environments enables us to navigate changing terrains and progressively improve gait patterns with rehabilitation. Here, we used a split-belt treadmill to study precisely how people save newly learned walking patterns. In Experiment 1, we investigated savings by systematically varying the learning and unlearning environments. Savings was predominantly influenced by 1) previous exposure to similar abrupt changes in the environment and 2) the amount of exposure to the new environment. Relearning was fastest when these two factors coincided, and we did not observe savings after the environment was introduced gradually during initial learning. In Experiment 2, we then studied whether people store explicit information about different walking environments that mirrors savings of a new walking pattern. Like savings, we found that previous exposure to abrupt changes in the environment also drove the ability to recall a previously experienced walking environment accurately. Crucially, the information recalled was extrinsic information about the learning environment (i.e., treadmill speeds) and not intrinsic information about the walking pattern itself. We conclude that simply learning a new walking pattern is not enough for long-term savings; rather, savings of a learned walking pattern involves recall of the environment or extended training at the learned state.

    Climate change is affecting agriculture doubly: evapotranspiration is increasing due to increments in temperature while the availability of water resources is decreasing. Furthermore, irrigated areas are expanding worldwide. In this study, the dynamics of climate change impacts on the water cycle of a newly irrigated watershed are studied through the calculation of soil water balances. The study area was a 752-ha watershed located on the left side of the Ebro river valley, in Northeast Spain. The soil water balance procedures were carried out throughout 1827 consecutive days (5 years) of hydrological and agronomical monitoring in the study area. Daily data from two agroclimatic stations were used as well. Evaluation of the impact of climate change on the water cycle considered the creation of two future climate scenarios for comparison: 2070 decade with climate change and 2070 decade without climate change. The main indicators studied were precipitation, irrigation, reference evapotranspiration, actual evapotranspiration, drainage from the watershed, and irrigation losses. The aridity index was also applied. The results represent a baseline scenario in which adaptation measures may be included and tested to reduce the impacts of climate change in the studied area and other similar areas.

    Two kinds of air duct cleaning methods, mechanical brushing with different brushes and compressed air cleaning, were compared in the laboratory and in newly built buildings. The ducts were contaminated either with test dust or with dust originated from a construction site. The amount of dust on the duct surface was measured with the vacuum test method and estimated visually before and after the cleaning. In addition, the cleaning times of the different techniques were compared and the amount of residual oil in the ducts was measured in the laboratory test. The brushing methods were more efficient in metal ducts, and compressed air cleaning was more efficient in plastic ducts. After the duct cleaning the mean amount of residual dust on the surface of the ducts was

    Ramon y Cajal described the fundamental morphology of the dendritic and axonal growth cones of neurons during development. However, technical limitations at the time prevented him from describing such growth cones from newborn neurons in the adult brain. The phenomenon of adult neurogenesis is briefly reviewed, and the structural description of dendritic and axonal outgrowth for these newly generated neurons in the adult brain is discussed. Axonal outgrowth into the hilus and CA3 region of the hippocampus occurs later than the outgrowth of dendrites into the molecular layer, and the ultrastructural analysis of axonal outgrowth has yet to be completed. In contrast, growth cones on dendrites from newborn neurons in the adult dentate gyrus have been described and this observation suggests that dendrites in adult brains grow in a similar way to those found in immature brains. However, dendrites in adult brains have to navigate through a denser neuropil and a more complex cell layer. Therefore, some aspects of dendritic outgrowth of neurons born in the adult dentate gyrus are different as compared to that found in development. These differences include the radial process of radial glial cells acting as a lattice to guide apical dendritic growth through the granule cell layer and a much thinner dendrite to grow through the neuropil of the molecular layer. Therefore, similarities and differences exist for dendritic outgrowth from newborn neurons in the developing and adult brain.

    Hormonal dysfunction involving the hypothalamic-pituitary-adrenal (HPA) axis, prolactin (PRL) secretion and sex hormone status has been supposed to contribute to the development or persistence of rheumatoid arthritis (RA). In addition, a reduced number of glucocorticoid receptors on circulating lymphocytes has been found in patients with RA. However, so far most studies have been performed in pre-treated patients. A combined test for total anterior pituitary reserve was performed in 10 patients with newly diagnosed untreated RA. Before and after stimulation with the respective hypothalamic releasing hormones, RA patients showed no difference in plasma concentrations of adrenocorticotrophic hormone (ACTH), cortisol, prolactin (PRL) and thyroid-stimulating hormone (TSH) when compared to healthy controls. In contrast, the growth hormone (GH) response to growth hormone-releasing hormone (GHRH) was blunted in RA patients. The hypothalamic-pituitary-thyroid/gonadal and adrenal axes seem to be unaltered in RA. However, if one considers the presence of chronic inflammation, normal plasma ACTH and cortisol concentrations must be considered as inappropriately low. The observed blunted GH release could be mediated by cytokines (e.g. IL-1), which are known to be elevated in RA.

    Lever-propelled wheelchairs have been described as more efficient and less physically demanding than hand-rim-propelled wheelchairs. To evaluate a newly designed lever mechanism (MARC) in both one- and two-arm use, a series of wheelchair exercise tests were performed on a motor-driven treadmill. Eight able-bodied male subjects performed a standard exercise test in the prototype MARC, both in an asynchronic and a synchronic bimanual propelling mode and in an unilateral (left-sided) mode. Subsequently the subjects performed additional exercise tests in a conventional crank-to-rod lever mechanism with unilateral and bimanual propulsion and in a conventional hand rim wheelchair. Analysis of variance was used to study the effect of the different work modes upon power output and cardiorespiratory parameters statistically (p < 0.05). The MARC stood out well in comparison with the conventional lever design. The additional design features which are to be implemented (variable gearing, reverse gear) will make the MARC a useful wheelchair. One-arm wheelchair propulsion is a very strenuous form of locomotion, requiring careful consideration in terms of provision. Mechanical and ergonomic improvements are quite feasible in lever propulsion and may to a certain extent reduce this problem. To improve overall mobility of wheelchair-dependent subjects further, ergonomic and mechanical design improvements are very necessary in lever as well as hand-rim wheelchairs. A combined biomechanical and physiological research approach will help in the definition of design criteria and fitting guidelines. PMID:8169940

This paper proposes a 4-stage framework for the dynamics of a system of cities in a developing country undergoing industrialization and encompassing both nonindustrial and industrial development. The synthesis is assessed with evidence from the newly industrializing Asian nations of Korea, Malaysia, and Taiwan. The 4 stages of cities' industrial change include 1) increasing primacy with industrial satellites, 2) increasing primacy with industrial satellites and nodal towns on a transport network, 3) rapidly increasing primacy with rapidly growing industrial satellites and nodal towns on the transport network, and 4) decreasing primacy with slowly growing industrial satellites and rapidly growing peripheral industrial towns. The 4-stage synthesis suggests that economic development in the periphery may occur even while the primate city maintains its hegemony over control and coordination functions. Peripheral industrial growth does not challenge this hegemony. The growth of industrial cities is, instead, part of a process of regional specialization in which the low cost labor in the periphery becomes an attraction for industry. These stages are not inevitable. Government efforts are necessary to develop rural areas in terms of social improvements (education and health), capital infrastructure (transportation and utilities), and fair payments to farmers for their outputs. These seem to be the lessons learned from the industrialization process in Korea, Malaysia, and Taiwan.

    The management of acute promyelocytic leukemia (APL) has considerably evolved during the past two decades. The advent of all-trans retinoic acid (ATRA) and its inclusion in combinatorial regimens with anthracycline chemotherapy has provided cure rates exceeding 80%; however, this widely adopted approach also conveys significant toxicity including severe myelosuppression and rare occurrence of secondary leukemias. More recently, the advent of arsenic trioxide (ATO) and its use in association with ATRA with or without chemotherapy has further improved patient outcome by allowing to minimize the intensity of chemotherapy, thus reducing serious toxicity while maintaining high anti-leukemic efficacy. The advantage of ATRA-ATO over ATRA chemotherapy has been recently demonstrated in two large randomized trials and this option has now become the new standard of care in low-risk (i.e. non-hyperleukocytic) patients. In light of its rarity, abrupt onset and high risk of early death and due to specific treatment requirements, APL remains a challenging condition that needs to be managed in highly experienced centers. We review here the results of large clinical studies conducted in newly diagnosed APL as well as the recommendations for appropriate diagnosis, prevention and management of the main complications associated with modern treatment of the disease.

    We present an abundance analysis for two newly discovered α-poor stars based on high-resolution spectroscopy. These stars were previously identified in the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data Release 1 as candidate α-poor stars. We observed these candidate α-poor stars with the Magellan Inamori Kyocera Echelle (MIKE) spectrograph on the 6.5 m Magellan-Clay Telescope located at Las Campanas Observatory. This high-resolution analysis confirms the low [α/Fe] abundance ratios for these stars compared to those of the majority of Galactic stars with comparable metallicities ([Fe/H] ∼ -0.5). The large deficiencies of α-elements suggest that these stars possess an anomalous chemical enrichment history. To have found such α-poor stars in our sample indicates that large scatters of the α-element abundance ratios may exist near solar metallicity. These results also demonstrate that our method is capable of selecting α-poor stars from low-resolution stellar spectra.

    Fine phosphor Y2O3:Eu3+ particles has advanced properties compare to conventional particles applied for compact fluorescent lamp (CFL) as three band phosphor. However, suspension of fine particles easily agglomerated during preparation of spray coating of the CFL tube. Therefore, it is introduced newly developed beads mill system to disperse fine phosphor. The beads mill consist of glass beads, dispersing chamber (impellers), separator chamber, slurry pump and motors. The first important performance of beads mill is the performance of the designed on separating the beads with the suspended fine particles. We report the development of beads mill and its separation performance vary in flow rate and separator rotation speeds. The 27 kg of glass beads with 30 µm in size was poured into dispersing chamber and then water was pumped continuously through the slurry pump. The samples for the separation test was obtained every 1 hours vary in rotation speed and slurry flow rate. The results shows that the separation performance was 99.99 % obtained for the rotation speed of >1000 rpm and flow rate of 8 L/minute. The performances of the system was verified by dispersing fine phosphor Y2O3:Eu3+ particles with concentration 1 wt.%. From the observed size distribution of particles after beads mill, it is concluded that the current design of bead mill effectively dispersed fine phosphor Y2O3:Eu3+.

    The Federal Institute for Geosciences and Natural Resources in Hannover owns a Sikorsky S-76B helicopter for geophysical and remote sensing airborne surveys. This platform has been completely refurbished and in parts newly designed to be fit for easy installations of complex geophysical instruments underneath, upon and within the helicopter. The airborne platform is equipped with a modern basic navigation equipment consisting of several GNSS antennae, state of the art inertial navigation systems, laser altimeter and video camera systems. Different other modules can be added to the helicopter as a state of the art gamma spectrometer, a laser scanner, airborne gravity meters etc. within the cabin. Moreover, external sensing systems as a photogrammetric camera, infraread camera or optional mulitspectral systems can be installed on the outer skin of the cabin. Different kinds of bird systems towed underneath the helicopter can be hooked up using standard cabling, glas fibres or wireless LAN. Available birds are equipped for frequency domain electromagnetics or gradient magnetics (IPHT Jena & Supracon, Jena). Besides, large georadar systems can be installed as well. The helicopter is able as well to carry TEM-gear or system in development. Main survey targets are groundwater systems, mineral deposits and natural hazards.

    Prostate cancer is the most common cancer affecting males in developed countries. It shows consistent evidence of familial aggregation, but the causes of this aggregation are mostly unknown. To identify common alleles associated with prostate cancer risk, we conducted a genome-wide association study (GWAS) using blood DNA samples from 1,854 individuals with clinically detected prostate cancer diagnosed at newly identified loci contain candidate susceptibility genes: MSMB, LMTK2 and KLK3.

  13. Mass-independent isotope effects.

    PubMed

    Buchachenko, Anatoly L

    2013-02-28

    Three fundamental properties of atomic nuclei-mass, spin (and related magnetic moment), and volume-are the source of isotope effects. The mostly deserved and popular, with almost hundred-year history, is the mass-dependent isotope effect. The first mass-independent isotope effect which chemically discriminates isotopes by their nuclear spins and nuclear magnetic moments rather than by their masses was detected in 1976. It was named as the magnetic isotope effect because it is controlled by magnetic interaction, i.e., electron-nuclear hyperfine coupling in the paramagnetic species, the reaction intermediates. The effect follows from the universal physical property of chemical reactions to conserve angular momentum (spin) of electrons and nuclei. It is now detected for oxygen, silicon, sulfur, germanium, tin, mercury, magnesium, calcium, zinc, and uranium in a great variety of chemical and biochemical reactions including those of medical and ecological importance. Another mass-independent isotope effect was detected in 1983 as a deviation of isotopic distribution in reaction products from that which would be expected from the mass-dependent isotope effect. On the physical basis, it is in fact a mass-dependent effect, but it surprisingly results in isotope fractionation which is incompatible with that predicted by traditional mass-dependent effects. It is supposed to be a function of dynamic parameters of reaction and energy relaxation in excited states of products. The third, nuclear volume mass-independent isotope effect is detected in the high-resolution atomic and molecular spectra and in the extraction processes, but there are no unambiguous indications of its importance as an isotope fractionation factor in chemical reactions.

  14. Expanded HTA, Legitimacy and Independence

    This brief commentary seeks to develop the analysis of Daniels, Porteny and Urrutia of the implications of expansion of the scope of health technology assessment (HTA) beyond issues of safety, efficacy, and cost-effectiveness. Drawing in particular on experience in the United Kingdom, it suggests that such expansion can be understood not only as a response to the problem of insufficiency of evidence, but also to that of legitimacy. However, as expansion of HTA also renders it more visibly political in character, it is plausible that its legitimacy may be undermined, rather than enhanced by, independence from the policy process.

  15. Independent Component Analysis of Textures

    2000-01-01

    A common method for texture representation is to use the marginal probability densities over the outputs of a set of multi-orientation, multi-scale filters as a description of the texture. We propose a technique, based on Independent Components Analysis, for choosing the set of filters that yield the most informative marginals, meaning that the product over the marginals most closely approximates the joint probability density function of the filter outputs. The algorithm is implemented using a steerable filter space. Experiments involving both texture classification and synthesis show that compared to Principal Components Analysis, ICA provides superior performance for modeling of natural and synthetic textures.

    2009-01-01

    The indistinguishability of independent single photons is presented by decomposing the single photon pulse into the mixed state of different transform-limited pulses. The entanglement between single photons and outer environment or other photons induces the distribution of the center frequencies of those transform-limited pulses and makes photons distinguishable. Only the single photons with the same transform-limited form are indistinguishable. In details, the indistinguishability of single photons from the solid-state quantum emitter and spontaneous parametric down-conversion is examined with two-photon Hong-Ou-Mandel interferometer. Moreover, experimental methods to enhance the indistinguishability are discussed, where the usage of spectral filter is highlighted.

    The Shuttle program is one of the most complex engineering activities undertaken anywhere in the world at the present time. The Space Shuttle Independent Assessment Team (SIAT) was chartered in September 1999 by NASA to provide an independent review of the Space Shuttle sub-systems and maintenance practices. During the period from October through December 1999, the team led by Dr. McDonald and comprised of NASA, contractor, and DOD experts reviewed NASA practices, Space Shuffle anomalies, as well as civilian and military aerospace experience. In performing the review, much of a very positive nature was observed by the SIAT, not the least of which was the skill and dedication of the workforce. It is in the unfortunate nature of this type of review that the very positive elements are either not mentioned or dwelt upon. This very complex program has undergone a massive change in structure in the last few years with the transition to a slimmed down, contractor-run operation, the Shuttle Flight Operations Contract (SFOC). This has been accomplished with significant cost savings and without a major incident. This report has identified significant problems that must be addressed to maintain an effective program. These problems are described in each of the Issues, Findings or Observations summarized, and unless noted, appear to be systemic in nature and not confined to any one Shuttle sub-system or element. Specifics are given in the body of the report, along with recommendations to improve the present systems.

    Independent component analysis (ICA) and blind source separation (BSS) methods are increasingly used to separate individual brain and non-brain source signals mixed by volume conduction in electroencephalographic (EEG) and other electrophysiological recordings. We compared results of decomposing thirteen 71-channel human scalp EEG datasets by 22 ICA and BSS algorithms, assessing the pairwise mutual information (PMI) in scalp channel pairs, the remaining PMI in component pairs, the overall mutual information reduction (MIR) effected by each decomposition, and decomposition ‘dipolarity’ defined as the number of component scalp maps matching the projection of a single equivalent dipole with less than a given residual variance. The least well-performing algorithm was principal component analysis (PCA); best performing were AMICA and other likelihood/mutual information based ICA methods. Though these and other commonly-used decomposition methods returned many similar components, across 18 ICA/BSS algorithms mean dipolarity varied linearly with both MIR and with PMI remaining between the resulting component time courses, a result compatible with an interpretation of many maximally independent EEG components as being volume-conducted projections of partially-synchronous local cortical field activity within single compact cortical domains. To encourage further method comparisons, the data and software used to prepare the results have been made available (http://sccn.ucsd.edu/wiki/BSSComparison). PMID:22355308

  20. Newly Commissioned Green Bank Telescope Bags New Pulsars

    2002-01-01

    Astronomers using the National Science Foundation's newly commissioned Robert C. Byrd Green Bank Telescope (GBT) have discovered a windfall of three previously undetected millisecond pulsars in a dense cluster of stars in the Milky Way Galaxy. The Green Bank Telescope The Robert C. Byrd Green Bank Telescope "This globular cluster, known as Messier 62, has been very well studied, and it would have been an exciting discovery to find just one new pulsar. The fact that we were able to detect three new pulsars at one time is simply remarkable," said Bryan Jacoby, a graduate student at the California Institute of Technology who led the research team. Results of the discovery were recently announced in an International Astronomical Union Circular. Jacoby and his colleague Adam Chandler, also a graduate student at Caltech, used the GBT to search for new pulsars in addition to the three already known in this cluster. Their research was part of the GBT's Early Science Program, which allows scientific investigations during the testing and commissioning of the telescope. The researchers used the Berkeley-Caltech Pulsar Machine, a new instrument whose development was overseen by Donald Backer at the University of California at Berkeley, to process the signals from the GBT and record them for later analysis. After their data were analyzed, the researchers discovered the telltale signatures of three additional pulsars and their white dwarf companion stars. Pulsars are rapidly rotating neutron stars that emit intense beams of radio waves along their misaligned magnetic axes. When these beams intersect the Earth, we see the pulsar flash on and off. Due to their exquisitely steady rotation, pulsars allow astronomers to study the basic laws of physics and the ways in which these dense clusters and exotic stellar systems are formed. Astronomers study globular clusters because they are among the oldest building blocks of our Galaxy. With their very dense stellar populations, these

    Objective: Glass carbomer cement represents a new generation of dental material, which mineralizes gradually into fluorapatite. The aim of this study was to evaluate the microleakage and marginal integrity of newly developed glass carbomer cement with and without protective surface coating (SC) in primary molars. Methods: Standardized cavities were prepared on extracted human primary molars, and the teeth were randomly assigned into the following groups (n = 10/each): (1) conventional glass ionomer cement (GIC) without SC; (2) GIC with SC; (3) glass carbomer cement without SC; (4) glass carbomer cement with SC; and (5) compomer without SC. Following thermocycling (5 ± 2°C–55 ± 2°C, dwell time 15 s, 2000×), the specimens were immersed in 0.5% basic fuchsin solution, sectioned, and digitally photographed. Microleakage was evaluated quantitatively by using open-source image analysis toolkit (ImageJ), and the data were analyzed statistically by using Kruskal-Wallis and Conover’s Multiple Comparison tests (P=.05). Results: The greatest amount of dye leakage was observed in the uncoated glass carbomer specimens, followed by the uncoated glass ionomer group (P<.05). There was no significant difference between the microleakage values of coated glass ionomer, coated glass carbomer, and the compomer (P>.05). The following statistical ranking was observed among microleakage of the test materials: uncoated glass carbomer > uncoated glass ionomer > coated glass ionomer ≈ coated glass carbomer ≈ compomer. Uncoated glass carbomer exhibited severe internal ice crack-like lines. Conclusion: The use of the new glass carbomer cement without SC results in severe microleakage and catastrophic internal cracks. PMID:23408469

    On July 22, 2011 and in the active region NOAA 11259 there ap- peared the event of the ejection of solar atmospheric Hα surges. According to the full-disc Hα observations of the Big Bear Solar Observatory in United States, three consecutive surges at one and the same place in the north of the main spot of the active region were discovered. The trajectories of these three surges exhib- ited the figure of straight lines, and their integral configuration is like an inverted Eiffel Tower. The first two surges are quite similar, and in each of them there appeared two bright points in the northern part of the main spot. After several minutes, the surges appeared in the midst of bright points. When the bright- ness of the bright points attained the maximum value, the surges spouted out from the midst of bright points. And after reaching the maximum altitude, they quickly vanished. Before the ejection of the third surge took place, no bright points appeared. Besides, its maximal altitude is merely one half of that of the first two surges. Via a comparison with the SDO/HMI (Solar Dynamics Obser- vatory/Helioseismic and Magnetic Imager) data of radial magnetic fields, it is found that in more than one hour before the appearance of the first surge there emerged bipolar magnetic fields in the region of ejection. Besides, in several min- utes before the ejection of each Hα surge the magnetic fluxes of positive polarity diminished. Via our analysis it is found that there appeared reconnections be- tween the newly emerging satellite magnetic fields and the preexisting magnetic fields in the spot, and this caused the continuous ejections of Hα surges.

    The in-vehicle volatile organic compounds (VOCs) concentrations gains the attention of both car producers and users. In the present study, an attempt was made to determine if analysis of air samples collected from an unconditioned car cabin can be used as a quality control measure. The VOCs composition of in-vehicle air was analyzed by means of active sampling on Carbograph 1TD and Tenax TA sorbents, followed by thermal desorption and simultaneous analysis on flame ionization and mass detector (TD-GC/FID-MS). Nine newly produced cars of the same brand and model were chosen for this study. Within these, four of the vehicles were equipped with identical interior materials and five others differed in terms of upholstery and the presence of a sunroof; one car was convertible. The sampling event took place outside of the car assembly plant and the cars tested left the assembly line no later than 24 hr before the sampling took place. More than 250 compounds were present in the samples collected; the identification of more than 160 was confirmed by comparative mass spectra analysis and 80 were confirmed by both comparison with single/multiple compounds standards and mass spectra analysis. In general, aliphatic hydrocarbons represented more than 60% of the total VOCs (TVOC) determined. Depending on the vehicle, the concentration of aromatic hydrocarbons varied from 12% to 27% of total VOCs. The very short period between car production and sampling of the in-vehicle air permits the assumption that the entire TVOC originates from off-gassing of interior materials. The results of this study expand the knowledge of in-vehicle pollution by presenting information about car cabin air quality immediately after car production.

    Purpose: To evaluate the toxicity and efficacy of chemoradiotherapy with temozolomide (TMZ) administered in an intensified 1-week on/1-week off schedule plus indomethacin in patients with newly diagnosed glioblastoma. Patients and Methods: A total of 41 adult patients (median Karnofsky performance status, 90%; median age, 56 years) were treated with preirradiation TMZ at 150 mg/m{sup 2} (1 week on/1 week off), involved-field radiotherapy combined with concomitant low-dose TMZ (50 mg/m{sup 2}), maintenance TMZ starting at 150 mg/m{sup 2} using a 1-week on/1-week off schedule, plus maintenance indomethacin (25 mg twice daily). Results: The median follow-up interval was 21.7 months. Grade 4 hematologic toxicity was observed in 15 patients (36.6%). Treatment-related nonhematologic Grade 4-5 toxicity was reported for 2 patients (4.9%). The median progression-free survival was 7.6 months (95% confidence interval, 6.2-10.4). The 1-year survival rate was 73.2% (95% confidence interval, 56.8-84.2%). The presence of O{sup 6}-methylguanine-DNA methyltransferase (MGMT) gene promoter methylation in the tumor tissue was associated with significantly superior progression-free survival. Conclusion: The dose-dense regimen of TMZ administered in a 1-week on/1-week off schedule resulted in acceptable nonhematologic toxicity. Compared with data from the European Organization for Research and Treatment of Cancer/National Cancer Institute of Canada trial 26981-22981/CE.3, patients with an unmethylated MGMT gene promoter appeared not to benefit from intensifying the TMZ schedule regarding the median progression-free survival and overall survival. In contrast, data are promising for patients with a methylated MGMT promoter.

    Summary Purpose To evaluate the efficacy, tolerability, and effects on behavior and psychosocial functioning of lamotrigine monotherapy in children with newly diagnosed typical absence seizures. Patients and methods Children meeting enrollment criteria (n = 54) received a confirmatory 24-h ambulatory electroencephalogram (EEG) and then entered a Escalation Phase of up to 20-weeks during which lamotrigine was titrated until seizures were controlled or maximum dose (10.2 mg/kg) was reached. Seizure freedom was assessed by diary review and clinic hyperventilation (clinic HV) and then confirmed by EEG with hyperventilation (HV/EEG). Patients who maintained seizure freedom for two consecutive weekly visits were entered into the Maintenance Phase (n = 30). Diary, clinic HV, and HV/EEG data were supplemented with 24-h ambulatory EEG at baseline and the ends of the Escalation and Maintenance Phases. Health outcome assessments were completed at screening and at the end of the Maintenance Phase. Results By the end of the Escalation Phase, seizure-free rates (responders) were 59% by seizure diary (n = 51), 56% by HV/EEG (n = 54) (primary endpoint), and 49% by 24-h ambulatory EEG (n = 49). During the Maintenance Phase, 89% (week 24) and 86% (week 32) remained seizure free by diary (n = 28), 78% by clinic HV (n = 27), and 81% by 24-h ambulatory EEG (n = 26). Seizure freedom was first observed beginning at the fifth week of the Escalation Phase. The most frequent adverse events were headache and cough. Health outcome scores were either improved or unchanged at the end of the Maintenance Phase. Conclusions Lamotrigine monotherapy results in complete seizure freedom in a substantial number of children with typical absence seizures. Lamotrigine was well tolerated in this study. PMID:18778916

    Objectives: To estimate first-year health care charges for youth with newly diagnosed epilepsy seen within an interdisciplinary pediatric epilepsy team and examine demographic, clinical, and psychosocial predictors of annual charges. Methods: Retrospective chart review was conducted to extract medical, hospital, and physician billing data from the year following an epilepsy diagnosis for 258 patients (aged 2–18 years) seen in a New Onset Seizure Clinic between July 2011 and December 2012. Descriptive statistics were used to estimate per-patient total first-year charges and health care utilization patterns (e.g., hospitalizations, emergency department visits, outpatient visits). Univariate analyses examined differences in health care charges between demographic, clinical, and psychosocial factors. Predictors of health care charges were examined using hierarchical multiple regression analysis. Results: The estimated per-patient total first-year health care charge was $20,084 (95% confidence interval [CI] $16,491–$23,677). Charges were higher for patients who reported having seizures since diagnosis ($25,509; 95% CI $20,162–$30,856) and were associated with more antiepileptic drug side effects (r = 0.18; 95% CI 0.03–0.32). Controlling for demographic and clinical factors, poorer baseline health-related quality of life was associated with higher per-patient health care charges (B = −445.40; 95% CI −865 to −25). Conclusions: The economic impact of pediatric epilepsy in the year following diagnosis is substantial. Cost reduction efforts would be optimized by improving seizure control and targeting health-related quality of life, an outcome amenable to behavioral intervention. PMID:26163432

    Integrins αvβ3 and αvβ5 regulate angiogenesis and invasiveness in cancer, potentially by modulating activation of the transforming growth factor (TGF)-β pathway. The randomized phase III CENTRIC and phase II CORE trials explored the integrin inhibitor cilengitide in patients with newly diagnosed glioblastoma with versus without O6-methylguanine DNA methyltransferase (MGMT) promoter methylation. These trials failed to meet their primary endpoints. Immunohistochemistry was used to assess the levels of the target integrins of cilengitide, αvβ3 and αvβ5 integrins, of αvβ8 and of their putative target, phosphorylation of SMAD2, in tumor tissues from CENTRIC (n=274) and CORE (n=224). αvβ3 and αvβ5 expression correlated well in tumor and endothelial cells, but showed little association with αvβ8 or pSMAD2 levels. In CENTRIC, there was no interaction between the biomarkers and treatment for prediction of outcome. In CORE, higher αvβ3 levels in tumor cells were associated with improved progression-free survival by central review and with improved overall survival in patients treated with cilengitide. Integrins αvβ3, αvβ5 and αvβ8 are differentially expressed in glioblastoma. Integrin levels do not correlate with the activation level of the canonical TGF-β pathway. αvβ3 integrin expression may predict benefit from integrin inhibition in patients with glioblastoma lacking MGMT promoter methylation.

    Objectives This study sought to understand whether UK Foundation doctors perceived the phenomena of ethical erosion and empathy decline during their initial period of clinical practice, and if so, why this occurred. Methods This qualitative study used semi-structured interviews with nine doctors in their first year of clinical practice at Royal Bolton Hospital, UK. Participants were invited to discuss the definition of empathy, how individuals acquire and maintain empathic ability, perceptions of ethical erosion in the self and others, and how clinical experiences have influenced their empathic ability. The interviews were transcribed, and analysed to identify emergent themes. Results Each participant reported a conscious acknowledgement of empathy decline in their own and their colleagues’ early clinical experiences as doctors. Stressful working environments, the prioritisation of patients’ physical rather than psychological well-being, and the attitudes of senior colleagues were all suggested as possible causes. Some doctors believed that specialties with reduced patient contact had a culture which precluded empathy, and influenced their own practice. In addition, some described how their value judgements of patients had affected their ability to empathise. However, all doctors perceived that empathy skills were desirable in senior clinicians, and some believed that educational interventions may be useful in arresting ethical erosion.   Conclusions Newly qualified doctors are aware of ethical erosion in themselves and their colleagues as they begin clinical practice. This has serious implications for patient care. Improving working conditions may reverse this trend. Empathy skills training within undergraduate and postgraduate curricula may be a useful intervention. PMID:27608488

  10. When sounds become actions: higher-order representation of newly learned action sounds in the human motor system.

    In the absence of visual information, our brain is able to recognize the actions of others by representing their sounds as a motor event. Previous studies have provided evidence for a somatotopic activation of the listener's motor cortex during perception of the sound of highly familiar motor acts. The present experiments studied (a) how the motor system is activated by action-related sounds that are newly acquired and (b) whether these sounds are represented with reference to extrinsic features related to action goals rather than with respect to lower-level intrinsic parameters related to the specific movements. TMS was used to measure the correspondence between auditory and motor codes in the listener's motor system. We compared the corticomotor excitability in response to the presentation of auditory stimuli void of previous motor meaning before and after a short training period in which these stimuli were associated with voluntary actions. Novel cross-modal representations became manifest very rapidly. By disentangling the representation of the muscle from that of the action's goal, we further showed that passive listening to newly learnt action-related sounds activated a precise motor representation that depended on the variable contexts to which the individual was exposed during testing. Our results suggest that the human brain embodies a higher-order audio-visuo-motor representation of perceived actions, which is muscle-independent and corresponds to the goals of the action.

    Independent prescribing (IP) is a new form of prescriptive authority for mental health services. Very little is known about where IP is being implemented and factors to support or constrain its adoption. An opportunistic sample of 119 respondents made up of nurses, doctors, support workers, occupational therapists and social workers completed an online survey. The sample worked in adult, old age and substance misuse services. Hospital wards and community mental health teams were identified as the highest ranked areas for implementation. A total of 68% of the sample identified pharmacology as the area for further training. And 40% of the sample felt that IP had been introduced to make services more effective. This opportunistic sample supported IP as a means to offer greater patient choice and as a method to broaden the boundaries of nursing practice. Integral to this development is the link between the psychiatrist and IP nurse in terms of work allocation and supervision.

    The recognition of locomotion activities (e.g., walking, running, still) is important for a wide range of applications like indoor positioning, navigation, location-based services, and health monitoring. Recently, there has been a growing interest in activity recognition using accelerometer data. However, when utilizing only acceleration-based features, it is difficult to differentiate varying vertical motion states from horizontal motion states especially when conducting user-independent classification. In this paper, we also make use of the newly emerging barometer built in modern smartphones, and propose a novel feature called pressure derivative from the barometer readings for user motion state recognition, which is proven to be effective for distinguishing vertical motion states and does not depend on specific users’ data. Seven types of motion states are defined and six commonly-used classifiers are compared. In addition, we utilize the motion state history and the characteristics of people’s motion to improve the classification accuracies of those classifiers. Experimental results show that by using the historical information and human’s motion characteristics, we can achieve user-independent motion state classification with an accuracy of up to 90.7%. In addition, we analyze the influence of the window size and smartphone pose on the accuracy. PMID:26690163

    Storminess in the Baltic Sea region has significantly increased over the last 50 years. As we do not have meteorological data beyond 20th century, therefore the long-term changes in storminess (e.g., frequency and magnitude of the storms) and its impact on the coastal evolution are mostly unknown. This study aims to reconstruct the extreme storm events along the coast of Estonia in late Holocene, inferred from changes in grain-size distribution and concentration of aeolian sands preserved in peat deposits. Four cores in total were collected from bogs of coastal Estonia; three from west Estonian archipelago (Hiiumaa Island and Saaremaa Island); one from the northern coast of the mainland (Juminda Peninsula). Core from Saaremaa (166 cm) covers the last 2700 years, cores from Hiiumaa (171 cm and 330 cm) cover ca 4000 years, and core from Juminda (465 cm) covers ca 8500 years. All AMS dates (77) are converted to cal yrs BP. Analyses of LOI and grain size are carried out at every centimetre in order to obtain data for mineral matter content and concentration of sand particles. The Juminda core shows a consistently low content of mineral matter (LOI < 2%) without clear peaks over the last 8000 years. The LOI results at both Hiiumaa sites show that mineral matter content gradually decreases from 4000 to 1500 cal yrs BP and then becomes the lowest in the period of 1500-1000 cal yrs BP; since then, it becomes higher (up to 10%) with fluctuations and has a clear peak around 700 cal yrs BP. At Saaremaa, the overall trend of mineral matter content is similar to that at the Hiiumaa sites: gradual decline from 2700 to 1500 cal yrs BP, lowest in 1500-1000 cal yrs BP, and relatively high over the last millennium. Concentration of mineral particles reveal clear peaks of aeolian sands at each site. At northern Hiiumaa, concentration has peaks around 3500, 3000 and 2500 cal yrs BP and is relatively high over the last 700 years. At Saaremaa, concentration has peaked at 2100, 1600 and

    The river Ehen, NW England, has been designated as a Special Area of Conservation (SAC) as it hosts England's largest population of freshwater pearl mussels (M. margaritifera). One of the Ehen's main headwater tributary, Ben Gill, was diverted to Ennerdale Lake in the 1970s to help increase the volume of water available for abstraction. Concerns over this diversion on the hydrology and sediment dynamics of the Ehen has led to the reconnection of this temporary stream as part of a project designed to improve habitat conditions for mussels in the Ehen. The reconnection has involved the construction of a new section of channel, following the natural (pre-diversion) course of Ben Gill. This paper presents findings of research designed to track the morphological evolution of the newly created Ben Gill channel. The work follows a previous research in which fluvial dynamics in the Ehen were studied before the reconnection of Ben Gill. Morpho-sedimentary dynamics are analysed at multiple scales: from the movement of individual particles, to changes on channel morphology following competent flow events. Changes in the channel's grain size distributions have been investigated in different sections, while bed mobility has been assessed using a combination of radio frequency identification (RFID) tags inserted into representative particles and painted bed patches. Additionally, digital elevation models (DEMs) of the entire new channel have been constructed by means of automatic digital photogrammetry using high resolution aerial photography taken by an unmanned aerial vehicle (UAV). DEMs of difference (DoD) between major flow events have been used to track lateral and longitudinal changes in the channel at a spatial resolution of less than 5cm. Finally, in order to link sedimentological changes in the new channel to its impact on the main stem Ehen, morpho-sedimentary changes of a gravel bar at the confluence have been monitored combining tracers (i.e. RFID) and repeated

    Abstract. Immigration and local recruitment play a central role in determining the growth rate of breeding populations. Unraveling these processes in newly established pop- ulations is of great importance to increase our understanding of how species change their distributions in response to global change. We studied the largest colony of glossy ibis (Plegadis falcinellus) in Western Europe (established in 1996 in Doñana, SW-Spain) by using capture-recapture methods, count estimates, and projection matrix modeling to: (1) test the effect of resource availability and competition on local recruitment dynamics, (2) investigate the contribution of local recruitment vs. immigration on population growth, and (3) assess the role of this population in source/sink dynamics. We found different dynamics before and after the establishment of satellite colonies in Doñana in 2004. Between 1996 and 2003, the population increased rapidly, fueled by immigrants (≈ 58 breeding females/ yr). Between 2003 and 2007, however, both colony size increase and immigration were negligible. Immigration played a major role in colony growth, but simultaneously this colony was a source population driving expansion of the species range as suggested by (1) absolute and relative estimates of the observed growth rate relative to that predicted by self-recruitment, and (2) numerous observations of Doñana-born individuals breeding elsewhere. Local recruitment, which was particularly high for first-year individuals (probability > 0.8 for the early study years), was not directly related to resource availability or previous-year breeding success. Local recruitment decreased rapidly at a threshold population size, however, when other satellite colonies became established at Dofiana. Our study suggests that even when recruitment at an early age and high productivity are observed, immigration can still play a pivotal role in promoting the fast growth of new populations at the edge of a species range, at

    The quadriceps femoris is traditionally described as a muscle group composed of the rectus femoris and the three vasti. However, clinical experience and investigations of anatomical specimens are not consistent with the textbook description. We have found a second tensor-like muscle between the vastus lateralis (VL) and the vastus intermedius (VI), hereafter named the tensor VI (TVI). The aim of this study was to clarify whether this intervening muscle was a variation of the VL or the VI, or a separate head of the extensor apparatus. Twenty-six cadaveric lower limbs were investigated. The architecture of the quadriceps femoris was examined with special attention to innervation and vascularization patterns. All muscle components were traced from origin to insertion and their affiliations were determined. A TVI was found in all dissections. It was supplied by independent muscular and vascular branches of the femoral nerve and lateral circumflex femoral artery. Further distally, the TVI combined with an aponeurosis merging separately into the quadriceps tendon and inserting on the medial aspect of the patella. Four morphological types of TVI were distinguished: Independent-type (11/26), VI-type (6/26), VL-type (5/26), and Common-type (4/26). This study demonstrated that the quadriceps femoris is architecturally different from previous descriptions: there is an additional muscle belly between the VI and VL, which cannot be clearly assigned to the former or the latter. Distal exposure shows that this muscle belly becomes its own aponeurosis, which continues distally as part of the quadriceps tendon.

    OBJECTIVES. The purpose of this study was to describe the establishment of a national surveillance system for newly acquired human immunodeficiency virus (HIV) infection and present the first 3 years' results. METHODS. All new cases of diagnosed HIV infection were reported to the national HIV surveillance center through state and territory health authorities. Information sought on each case included evidence of whether the infection had been newly acquired, defined by the diagnosis of HIV seroconversion illness or by the report of a negative or indeterminate HIV antibody test result occurring within the 12 months prior to diagnosis of infection. RESULTS. Of 3602 reported cases of HIV infection in adults and adolescents newly diagnosed in Australia between 1991 and 1993, 11.4% were identified as newly acquired. The majority (85%) of cases of newly diagnosed HIV infection occurred among men who reported homosexual contact, and 15% of these cases were identified as newly acquired. Average age at diagnosis was 31 years for cases of newly acquired infection and 34 years for other cases. CONCLUSIONS. Surveillance for newly acquired HIV infection has been established at a national level in Australia and provides valuable information for planning primary HIV prevention programs. PMID:7998631

  16. Methods to recruit hard-to-reach groups: comparing two chain referral sampling methods of recruiting injecting drug users across nine studies in Russia and Estonia.

    Evidence suggests rapid diffusion of injecting drug use and associated outbreaks of HIV among injecting drug users (IDUs) in the Russian Federation and Eastern Europe. There remains a need for research among non-treatment and community-recruited samples of IDUs to better estimate the dynamics of HIV transmission and to improve treatment and health services access. We compare two sampling methodologies "respondent-driven sampling" (RDS) and chain referral sampling using "indigenous field workers" (IFS) to investigate the relative effectiveness of RDS to reach more marginal and hard-to-reach groups and perhaps to include those with the riskiest behaviour around HIV transmission. We evaluate the relative efficiency of RDS to recruit a lower cost sample in comparison to IFS. We also provide a theoretical comparison of the two approaches. We draw upon nine community-recruited surveys of IDUs undertaken in the Russian Federation and Estonia between 2001 and 2005 that used either IFS or RDS. Sampling effects on the demographic composition and injecting risk behaviours of the samples generated are compared using multivariate analysis. Our findings suggest that RDS does not appear to recruit more marginalised sections of the IDU community nor those engaging in riskier injecting behaviours in comparison with IFS. RDS appears to have practical advantages over IFS in the implementation of fieldwork in terms of greater recruitment efficiency and safety of field workers, but at a greater cost. Further research is needed to assess how the practicalities of implementing RDS in the field compromises the requirements mandated by the theoretical guidelines of RDS for adjusting the sample estimates to obtain estimates of the wider IDU population.

    The present study focused on voice quality and the perception of the basic emotions from speech samples in cross-cultural conditions. It was examined whether voice quality, cultural, or language background, age, or gender were related to the identification of the emotions. Professional actors (n2) and actresses (n2) produced non-sense sentences (n32) and protracted vowels (n8) expressing the six basic emotions, interest, and a neutral emotional state. The impact of musical interests on the ability to distinguish between emotions or valence (on an axis positivity - neutrality - negativity) from voice samples was studied. Listening tests were conducted on location in five countries: Estonia, Finland, Russia, Sweden, and the USA with 50 randomly chosen participants (25 males and 25 females) in each country. The participants (total N = 250) completed a questionnaire eliciting their background information and musical interests. The responses in the listening test and the questionnaires were statistically analyzed. Voice quality parameters and the share of the emotions and valence identified correlated significantly with each other for both genders. The percentage of emotions and valence identified was clearly above the chance level in each of the five countries studied, however, the countries differed significantly from each other for the identified emotions and the gender of the speaker. The samples produced by females were identified significantly better than those produced by males. Listener's age was a significant variable. Only minor gender differences were found for the identification. Perceptual confusion in the listening test between emotions seemed to be dependent on their similar voice production types. Musical interests tended to have a positive effect on the identification of the emotions. The results also suggest that identifying emotions from speech samples may be easier for those listeners who share a similar language or cultural background with the

It was examined whether voice quality, cultural, or language background, age, or gender were related to the identification of the emotions. Professional actors (n2) and actresses (n2) produced non-sense sentences (n32) and protracted vowels (n8) expressing the six basic emotions, interest, and a neutral emotional state. The impact of musical interests on the ability to distinguish between emotions or valence (on an axis positivity – neutrality – negativity) from voice samples was studied. Listening tests were conducted on location in five countries: Estonia, Finland, Russia, Sweden, and the USA with 50 randomly chosen participants (25 males and 25 females) in each country. The participants (total N = 250) completed a questionnaire eliciting their background information and musical interests. The responses in the listening test and the questionnaires were statistically analyzed. Voice quality parameters and the share of the emotions and valence identified correlated significantly with each other for both genders. The percentage of emotions and valence identified was clearly above the chance level in each of the five countries studied, however, the countries differed significantly from each other for the identified emotions and the gender of the speaker. The samples produced by females were identified significantly better than those produced by males. Listener's age was a significant variable. Only minor gender differences were found for the identification. Perceptual confusion in the listening test between emotions seemed to be dependent on their similar voice production types. Musical interests tended to have a positive effect on the identification of the emotions. The results also suggest that identifying emotions from speech samples may be easier for those listeners who share a similar language or cultural background with the

    To study the impact of air pollution on the growth and elemental composition of conifers, 5 sample plots were established at different distances and directions from the Estonian Power Plant (Northeast Estonia) in 1999-2000. The selected stands were 75-80(85)-yr-old parts (0.05 ha) of (Oxalis)-Myrtillus site type forest of 0.7-0.8 density. The soils of all sample plots were Gleyic Podzols (Lkg) on sands. The several times higher Ca concentration in the humus horizon of the sample plot NE from the Estonian PP is caused by the prevailing westerly and southerly winds which carry more pollutants NE from the power plant than to SSW. To ascertain the effect of power plants on the growth of Scots pine (Pinus sylvestris L.), the length growth of the needles and shoots formed in 1997-2000, dry weight of 100 needles, and density of needles on the shoots were measured. As compared to the control, the strongest inhibition of growth was revealed in the sample plots situated 22 km north-east and 17 km south-west from the Estonian Power Plant. As compared to control, the needles of trees growing on sample plots closer to the power plant showed higher contents of Ca, S and Zn. The content of Mg in needles increased with distance from the pollution source. Current year needles had higher contents of Cu and Zn than older needles. Today the amounts of fly ash emitted from Narva power plants are fallen. Long-term fly ash emission has caused changes in the measurements of morphological parameters and chemical composition of needles.

    Burning oil shale to produce electricity has a dominant position in Estonia's energy sector. Around 90% of the overall electric energy production originates from the Narva Power Plants. The technology in use has been significantly renovated - two older types of pulverized fuel burning (PF) energy production units were replaced with new circulating fluidized bed (CFB) technology. Additional filter systems have been added to PF boilers to reduce emissions. Oil shale contains various amounts of natural radionuclides. These radionuclides concentrate and become enriched in different boiler ash fractions. More volatile isotopes will be partially emitted to the atmosphere via flue gases and fly ash. To our knowledge, there has been no previous study for CFB boiler systems on natural radionuclide enrichment and their atmospheric emissions. Ash samples were collected from Eesti Power Plant's CFB boiler. These samples were processed and analyzed with gamma spectrometry. Activity concentrations (Bq/kg) and enrichment factors were calculated for the (238)U ((238)U, (226)Ra, (210)Pb) and (232)Th ((232)Th, (228)Ra) family radionuclides and for (40)K in different CFB boiler ash fractions. Results from the CFB boiler ash sample analysis showed an increase in the activity concentrations and enrichment factors (up to 4.5) from the furnace toward the electrostatic precipitator block. The volatile radionuclide ((210)Pb and (40)K) activity concentrations in CFB boilers were evenly distributed in finer ash fractions. Activity balance calculations showed discrepancies between input (via oil shale) and output (via ash fractions) activities for some radionuclides ((238)U, (226)Ra, (210)Pb). This refers to a situation where the missing part of the activity (around 20% for these radionuclides) is emitted to the atmosphere. Also different behavior patterns were detected for the two Ra isotopes, (226)Ra and (228)Ra. A part of (226)Ra input activity, unlike (228)Ra, was undetectable in the

    GREEN BANK, WV -- New studies with the National Science Foundation's Robert C. Byrd Green Bank Telescope (GBT) have revealed a previously unknown population of discrete hydrogen clouds in the gaseous halo that surrounds the Milky Way Galaxy. These clouds were discovered in the transition zone between the Milky Way and intergalactic space, and provide tantalizing evidence that supernova-powered "galactic fountains" continually blast superheated hydrogen gas into our Galactic suburbs.

Credit: Kirk Woellert/National Science Foundation. Extending far above the star-filled disk of the Milky Way is an atmosphere, or halo, of hydrogen gas. "By studying this halo, we can learn a great deal about the processes that are going on inside our Galaxy as well as beyond its borders," said Jay Lockman, an astronomer with the National Radio Astronomy Observatory (NRAO) in Green Bank, West Virginia. "It has remained a mystery, however, how this halo formed and what has prevented gravitational forces from collapsing the gas into a thin layer long ago." Some astronomers have speculated that this gas is distributed as a diffuse mist held up by either magnetic fields or cosmic rays streaming out of the plane of the Milky Way. Others believed that it is made of innumerable long-lived hydrogen clouds bobbing up and down like balls tossed by a juggler. Early observations with other telescopes discovered that there was some neutral hydrogen gas floating far above the Galaxy's plane, but these instruments were not sensitive enough to reveal any structure or resolve questions about its origin. Lockman's studies for the first time show a clear picture of the structure of the gas. Rather than a mist, the halo is in fact full of discrete clouds, each containing 50-to-100 solar masses of hydrogen and averaging about 100

    The primary objective of the study was to assess the vitamin D (VD) status of patients suffering from ITP. Children from the case cohort (total 21) were recruited from chronic ITP patients (followed as outpatients) and newly diagnosed ITP (prospective study) patients. VD deficiency (values <75 nmol/L) was detected in 11 patients with newly diagnosed ITP, and seven patients with chronic ITP. Only three patients with newly diagnosed, and none with chronic ITP had normal VD values. Newly diagnosed ITP patients had statistically significantly higher values (P <.044) of VD than the patients with chronic type of ITP. Platelets values did not follow VD level. VD deficiency is very common in children with either newly diagnosed or chronic ITP form. Therefore there is a utility supplementing VD in these patients. To investigate the role of VD as an immune modulating drug for patients with ITP, a prospective randomized placebo-controlled trial needs to be performed. PMID:27312171

    Retail health clinics are an expanding health care delivery model and an emerging new practice site for nurse practitioners (NPs). Critical thinking skills, clinical competence, interprofessional collaboration, and business savvy are necessary for successful practice in this highly independent and autonomous setting. This article describes a pilot residency partnership program aimed at supporting new graduate NP transition to practice, reducing NP turnover, and promoting academic progression. Eight new graduate NPs were recruited to the pilot and paired with experienced clinical NP preceptors for a 12-month program that focused on increasing clinical and business competence in the retail health setting. The residency program utilized technology to facilitate case conferences and targeted Webinars to enhance learning and peer-to-peer sharing and support. An on-line doctoral-level academic course that focused on interprofessional collaboration in health care, population health, and business concepts was offered. Both NPs and preceptors were highly satisfied with the academic-service residency program between MinuteClinic and Northeastern University School of Nursing in Boston, MA. New NPs particularly valued the preceptor model, the clinical case conferences, and business Webinars. Because their priority was in gaining clinical experience and learning the business acumen relevant to managing the processes of care, they did not feel ready for the doctoral course and would have preferred to take later in their practice. The preceptors valued the academic course and felt that it enhanced their precepting and leadership skills. At the time of this article, 6 months post completion of the residency program, there has been no turnover. Our experience supports the benefits for residency programs for newly graduated NPs in retail settings. The model of partnering with academia by offering a course within a service organization's educational programs can enable academic

    A newly isolated strain, SJY1, identified as Ochrobactrum sp., utilizes nicotine as a sole source of carbon, nitrogen, and energy. Strain SJY1 could efficiently degrade nicotine via a variant of the pyridine and pyrrolidine pathways (the VPP pathway), which highlights bacterial metabolic diversity in relation to nicotine degradation. A 97-kbp DNA fragment containing six nicotine degradation-related genes was obtained by gap closing from the genome sequence of strain SJY1. Three genes, designated vppB, vppD, and vppE, in the VPP pathway were cloned and heterologously expressed, and the related proteins were characterized. The vppB gene encodes a flavin-containing amine oxidase converting 6-hydroxynicotine to 6-hydroxy-N-methylmyosmine. Although VppB specifically catalyzes the dehydrogenation of 6-hydroxynicotine rather than nicotine, it shares higher amino acid sequence identity with nicotine oxidase (38%) from the pyrrolidine pathway than with its isoenzyme (6-hydroxy-l-nicotine oxidase, 24%) from the pyridine pathway. The vppD gene encodes an NADH-dependent flavin-containing monooxygenase, which catalyzes the hydroxylation of 6-hydroxy-3-succinoylpyridine to 2,5-dihydroxypyridine. VppD shows 62% amino acid sequence identity with the hydroxylase (HspB) from Pseudomonas putida strain S16, whereas the specific activity of VppD is ∼10-fold higher than that of HspB. VppE is responsible for the transformation of 2,5-dihydroxypyridine. Sequence alignment and phylogenetic analysis suggested that the VPP pathway, which evolved independently from nicotinic acid degradation, might have a closer relationship with the pyrrolidine pathway. The proteins and functional pathway identified here provide a sound basis for future studies aimed at a better understanding of molecular principles of nicotine degradation. PMID:25344232

    Naftopidil is clinically for treatment of benign prostate hyperplasia, and emerging evidence has pointed to its anticancer effect. To obtain the anticancer drug with the potential greater than that of naftopidil, we have newly synthesized the naftopidil analogue HUHS1015. The present study investigated the mechanism underlying HUHS1015-induced apoptosis of human gastric cancer cells and assessed the possibility for clinical use as an innovative anticancer drug. HUHS1015 reduced cell viability for MKN28 human well-differentiated gastric adenocarcinoma cell line and MKN45 human poorly differentiated gastric adenocarcinoma cell line in a concentration (0.3-100 μM)-dependent manner more effectively than cisplatin, a chemo-drug widely used. In the flow cytometry using propidium iodide (PI) and annexin V, HUHS1015 significantly increased the population of PI-positive and annexin V-negative cells, corresponding to primary necrosis and that of PI-positive and annexin V-positive cells, corresponding to late apoptosis/secondary necrosis, both in the two cell types. HUHS1015 significantly activated caspase-3, caspase-4, and caspase-8 in MKN45 cells, while no obvious caspase activation was found in MKN28 cells. HUHS1015 upregulated expression of the tumor necrosis factor α (TNFα) mRNA and protein in MKN45 cells, allowing activation of caspase-8 through TNF receptor and the effector caspase-3. HUHS1015 clearly inhibited tumor growth in mice inoculated with MKN45 cells, with the survival rate higher than that for the anticancer drugs cisplatin, paclitaxel, and irinotecan. The results of the present study show that HUHS1015 induces caspase-independent and caspase-dependent apoptosis of MKN28 and MKN45 human gastric cancer cells, respectively, and effectively suppresses MKN45 cell proliferation.

    The primary objective of this study was to investigate factors associated with fatigue severity in newly diagnosed patients with higher-risk myelodysplastic syndromes (MDS). The secondary objectives were to assess symptom prevalence and to examine the relationships between fatigue, quality of life (QoL) and overall symptom burden in these patients. The analyses were conducted in 280 higher-risk MDS patients. Pre-treatment patient-reported fatigue was evaluated with the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue scale and QoL was assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). Female gender (P = 0·018), poor performance status (i.e., ECOG of 2-4) (P < 0·001) and lower levels of haemoglobin (Hb) (P = 0·026) were independently associated with higher fatigue severity. The three most prevalent symptoms were as follows: fatigue (92%), dyspnoea (63%) and pain (55%). Patients with higher levels of fatigue also had greater overall symptom burdens. The mean global QoL scores of patients with the highest versus those with the lowest levels of fatigue were 29·2 [standard deviation (SD), 18·3] and 69·0 (SD, 18·8), respectively and this difference was four times the magnitude of a clinically meaningful difference. Patient-reported fatigue severity revealed the effects of disease burden on overall QoL more accurately than did degree of anaemia. Special attention should be given to the female patients in the management of fatigue. PMID:25272332

    Obstructive sleep apnea (OSA) is accompanied by cognitive, motor, autonomic, learning, and affective abnormalities. The putamen serves several of these functions, especially motor and autonomic behaviors, but whether global and specific sub-regions of that structure are damaged is unclear. We assessed global and regional putamen volumes in 43 recently-diagnosed, treatment-naïve OSA (age, 46.4 ± 8.8 years; 31 male) and 61 control subjects (47.6 ± 8.8 years; 39 male) using high-resolution T1-weighted images collected with a 3.0-Tesla MRI scanner. Global putamen volumes were calculated, and group differences evaluated with independent samples t-tests, as well as with analysis of covariance (covariates; age, gender, and total intracranial volume). Regional differences between groups were visualized with 3D surface morphometry-based group ratio maps. OSA subjects showed significantly higher global putamen volumes, relative to controls. Regional analyses showed putamen areas with increased and decreased tissue volumes in OSA relative to control subjects, including increases in caudal, mid-dorsal, mid-ventral portions, and ventral regions, while areas with decreased volumes appeared in rostral, mid-dorsal, medial-caudal, and mid-ventral sites. Global putamen volumes were significantly higher in the OSA subjects, but local sites showed both higher and lower volumes. The appearance of localized volume alterations points to differential hypoxic or perfusion action on glia and other tissues within the structure, and may reflect a stage in progression of injury in these newly-diagnosed patients toward the overall volume loss found in patients with chronic OSA. The regional changes may underlie some of the specific deficits in motor, autonomic, and neuropsychologic functions in OSA.

    Variability in daily blood pressure (BPV) recorded 24-h ambulatory blood pressure monitoring (ABPM) is known to be related to left ventricular hypertrophy and an increased incidence of cardiovascular events in hypertensive patients. The aim of this study was to evaluate whether left atrium dimension, which increases early in hypertensive subjects, was related to BPV in a group of 167 drug-naive patients (100M/67F, age: 46±11yr). The patients were chosen among those consecutively sent by their general practitioners to confirm the existence of arterial hypertension and afterwards diagnosed as hypertensive (mean 24-h ABPM ⩾130/80 mm Hg). In each patient, the left atrial posteroanterior diameter index for height (LADi) and the left ventricular mass standardized for body surface area (LVMi) were measured using standardized echocardiographic methods. BPV was calculated as the weighted mean of daytime and nighttime systolic and diastolic blood pressure s.d.'s (ws.d.), according to the formula ws.d.=[(daytime s.d. × 10)+nighttime s.d. × 6)]/16. An increase in left atrial dimension (LADi>24 mm m(-1)) was present in 36 patients (21.6% of the total population). In a univariate regression, LVMi was significantly related to systolic BPV (r=0.24; P=0.02) only in men, whereas LADi was significantly related to both systolic and diastolic BPV in both genders. After adjusting for sex, age, BMI, heart rate, diastolic function and estimated glomerular filtration rate, both systolic and diastolic BPV remained significantly related to LADi (P=0.02 for both) but not to LVMi. In conclusion, this study suggests that BVP, as measured as BPws.d., is significantly and independently associated with increased LADi in newly diagnosed, treatment-naive hypertensive patients.

    Magnetic loops are building blocks of the closed-field corona. While active region loops are readily seen in images taken at EUV and X-ray wavelengths, quiet-Sun (QS) loops are seldom identifiable and are therefore difficult to study on an individual basis. The first analysis of solar minimum (Carrington Rotation 2077) QS coronal loops utilizing a novel technique called the Michigan Loop Diagnostic Technique (MLDT) is presented. This technique combines Differential Emission Measure Tomography and a potential field source surface (PFSS) model, and consists of tracing PFSS field lines through the tomographic grid on which the local differential emission measure is determined. As a result, the electron temperature T{sub e} and density N{sub e} at each point along each individual field line can be obtained. Using data from STEREO/EUVI and SOHO/MDI, the MLDT identifies two types of QS loops in the corona: so-called up loops in which the temperature increases with height and so-called down loops in which the temperature decreases with height. Up loops are expected, however, down loops are a surprise, and furthermore, they are ubiquitous in the low-latitude corona. Up loops dominate the QS at higher latitudes. The MLDT allows independent determination of the empirical pressure and density scale heights, and the differences between the two remain to be explained. The down loops appear to be a newly discovered property of the solar minimum corona that may shed light on the physics of coronal heating. The results are shown to be robust to the calibration uncertainties of the EUVI instrument.

  12. Caspase-independent cell deaths.

    PubMed

    Lockshin, Richard A; Zakeri, Zahra

    2002-12-01

    A very common and the best understood of the mechanisms of physiological cell death is apoptosis, resulting from the activation, through either of two primary pathways, of site-specific proteases called caspases. There are, however, many other routes to cell death, prominently including autophagy and proteasomal degradation of critical constituents of cells. These routes are frequently seen in experimental situations in which initiator or effector caspases are inhibited or blocked through genetic means, but they are also encountered during normal physiological and pathological processes. Most frequently, autophagic or proteasomal degradation is used to eliminate massive cytoplasm of very large cells, especially post-mitotic cells, and these pathways are prominent even though caspase genes, messages, and pro-enzymes are found in the cells. These forms of cell death are fully physiological and not simply a default pathway for a defective cell; and they are distinct from necrosis. We do not yet understand the extent to which the pathways are linked, what mechanisms trigger the caspase-independent deaths, and how the choices are made.

    The performance and maturity of a preprototype, three-person capacity, automatically controlled and monitored, self-contained independent air revitalization subsystem were evaluated. The subsystem maintains the cabin partial pressure of oxygen at 22 kPa (3.2 psia) and that of carbon dioxide at 400 Pa (3 mm Hg) over a wide range of cabin air relative humidity conditions. Consumption of water vapor by the water vapor electrolysis module also provides partial humidity control of the cabin environment. During operation, the average carbon dioxide removal efficiency at baseline conditions remained constant throughout the test at 84%. The average electrochemical depolarized concentrator cell voltage at the end of the parametric/endurance test was 0.41 V, representing a very slowly decreasing average cell voltage. The average water vapor electrolysis cell voltage increased only at a rate of 20 mu/h from the initial level of 1.67 V to the final level of 1.69 V at conclusion of the testing.

    The clinical performance of newly qualified staff nurses, or their 'fitness for purpose' has become a central professional and corporate issue and highlighted as a central causes for the reforms recommended by the Peach report (Peach 1999). However the ability to gauge the performance of newly qualified nurses remains a largely subjective exercise relying upon anecdotal evidence or general statements of newly qualified nurses' feelings of inadequacy on qualification. This article seeks to address this issue by reporting the findings of project that sought to compare the expectations of senior nurses regarding the level of competence of newly qualified nurses with that of the actual level of competency as assessed by the preceptors after 8 weeks in post. Using a specifically designed instrument to assess clinical competency a comparison has been made between 139 senior nurses' expectations of the competency of newly qualified nurses and the actual competence as assessed by preceptors of 36 newly qualified nurses after 8 weeks in post. The findings indicate that the senior nurses have clear subjective expectations of the competence level of newly qualified nurses. However these expectations are consistently lower than the actual level of competency demonstrated by the newly qualified nurses as assessed by their preceptors. This research demonstrates that through the use of a validated tool newly qualified nurses consistently perform at a higher level of competency than that expected by senior nurses. The ability to estimate competency levels by objective means should be developed. Further research is needed involving a larger sample of Trusts and Schools of Nursing to replicate the results of this study and to compare methods of the assessment of performance in terms of competency in practice on qualification. It is through developments based upon research such as this that a systematic evaluation of the contribution of Schools of Nursing to the competence of newly

  18. Facilitating independence: The benefits of a post-diagnostic support project for people with dementia.

    PubMed

    Kelly, Fiona; Innes, Anthea

    2016-03-01

    Providing support in the form of information, advice and access to services or social events is promoted as beneficial for people newly diagnosed with dementia and their families. This paper reports on key findings from an evaluation of a post-diagnostic support pilot project in Scotland addressing local service gaps, namely information provision, emotional and practical support and maintaining community links. Twenty-seven participants (14 people newly diagnosed with dementia and 13 family carers) were interviewed at two time points: T1 shortly after joining the pilot project and T2 approximately six months later, to ascertain their views on existing services and the support offered by the pilot project. A comparative thematic analysis revealed that the project facilitated increased independence (associated with increased motivation and self-confidence) of people with dementia. The project illustrates what can be achieved if resources are targeted at providing individualised post-diagnostic support, particularly where there are service delivery gaps.

    Lymphedema caused by the dissection of lymphatic node for treating a breast cancer produces serious swelling on the limbs and reduces the quality of life of the patient. For quantitative assessing the disease, this study newly proposed the stiffness measurement method of upper limb with lymphedema. A measurement system, where a roll-up belt was installed to circularly compress the limb by pulling the belt was developed. Both the belt tension and displacement were measured during the compresson of limb. Scale-independent stiffness index was newly derived from the bulk modulus and applied the measured force and displacement. The stiffness index of upper limb with lymphedema was measured. The index of affected limb was larger than that of healthy limb in a patient.

    The Independent Payment Advisory Board (IPAB) is a vastly powerful component of the president's health care reform law, with authority to issue recommendations to reduce the growth in Medicare spending, providing recommendations to be considered by Congress and implemented by the administration on a fast track basis. Ever since its inception, IPAB has been one of the most controversial issues of the Patient Protection and Affordable Care Act (ACA), even though the powers of IPAB are restricted and multiple sectors of health care have been protected in the law. IPAB works by recommending policies to Congress to help Medicare provide better care at a lower cost, which would include ideas on coordinating care, getting rid of waste in the system, providing incentives for best practices, and prioritizing primary care. Congress then has the power to accept or reject these recommendations. However, Congress faces extreme limitations, either to enact policies that achieve equivalent savings, or let the Secretary of Health and Human Services (HHS) follow IPAB's recommendations. IPAB has strong supporters and opponents, leading to arguments in favor of or against to the extreme of introducing legislation to repeal IPAB. The origins of IPAB are found in the ideology of the National Institute for Health and Clinical Excellence (NICE) and the impetus of exploring health care costs, even though IPAB's authority seems to be limited to Medicare only. The structure and operation of IPAB differs from Medicare and has been called the Medicare Payment Advisory Commission (MedPAC) on steroids. The board membership consists of 15 full-time members appointed by the president and confirmed by the Senate with options for recess appointments. The IPAB statute sets target growth rates for Medicare spending. The applicable percent for maximum savings appears to be 0.5% for year 2015, 1% for 2016, 1.25% for 2017, and 1.5% for 2018 and later. The IPAB Medicare proposal process involves

    Copper is becoming recognised as a key cation in a variety of biological processes. Copper chelation has been studied as a potential anti-angiogenic strategy for arresting tumour growth. Conversely the delivery of copper ions and complexes in vivo can elicit a pro-angiogenic effect. Previously we unexpectedly found that copper-stimulated intraperitoneal angiogenesis was accompanied by collagen deposition. Here, in hard tissue, not only was healing accelerated by copper, but again enhanced deposition of collagen was detected at 2 weeks. Experiments with reconstituted collagen showed that addition of copper ions post-fibrillogenesis rendered plastically-compressed gels resistant to collagenases, enhanced their mechanical properties and increased the denaturation temperature of the protein. Unexpectedly, this apparently interfibrillar crosslinking was not affected by addition of glucose or ascorbic acid, which are required for crosslinking by advanced glycation end products (AGEs). Fibroblasts cultured on copper-crosslinked gels did not proliferate, whereas those cultured with an equivalent quantity of copper on either tissue culture plastic or collagen showed no effect compared with controls. Although non-proliferative, fibroblasts grown on copper-cross-linked collagen could migrate, remained metabolically active for at least 14 days and displayed a 6-fold increase in Mmps 1 and 3 mRNA expression compared with copper-free controls. The ability of copper ions to crosslink collagen fibrils during densification and independently of AGEs or Fenton type reactions is previously unreported. The effect on MMP susceptibility of collagen and the dramatic change in cell behaviour on this crosslinked ECM may contribute to shedding some light on unexplained phenomena as the apparent benefit of copper complexation in fibrotic disorders or the enhanced collagen deposition in response to localised copper delivery.

  3. Use of reverse-transcriptase-based HIV-1 viral load assessment to confirm low viral loads in newly diagnosed patients in Switzerland

    PubMed Central

    2014-01-01

    Background Treatment-naïve patients newly diagnosed with HIV occasionally present with low viral RNA of ≤1’000 copies/ml, raising concerns about viral load underestimation. Because falsely low or undetectable viral loads might lead to inadvertent virus transmission or treatment delays, confirmation of such cases by a sequence-independent viral load test is recommended in Switzerland. Methods HIV-1 RNA ≤1’000 cp/ml by Roche’s or Abbott’s tests in patients newly diagnosed from 2010 to 2012 in Switzerland were subjected to viral load testing by the product-enhanced-reverse transcriptase (PERT) assay. These investigations were complemented with repeat and/or alternative viral RNA measurements. Results HIV-1 RNA ≤1’000 cp/ml was observed in 71 of 1814 newly diagnosed patients. The PERT assay suggested clinically relevant viral load underestimation in 7 of 32 cases that could be investigated. In four patients, the PERT viral load was 10-1’000-fold higher; this was confirmed by alternative HIV-1 RNA tests. Six of the 7 underestimates had been obtained with meanwhile outdated versions of Roche’s HIV-1 RNA test. In the seventh patient, follow-up revealed similar results for RNA and PERT based viral loads. Conclusion PERT assay revealed occasional severe viral load underestimation by versions of HIV-1 RNA tests meanwhile outdated. Underestimation by contemporary tests appears rare, however.

    Lin, Andrew; Othus, Megan; McQuary, Amy; Chi, Mary; Estey, Elihu

    2015-01-01

    Background Increased body mass index (BMI) is associated with increased risk of treatment-related complications and inferior overall survival in children and adolescents with AML. The growing proportion of the general population who are obese raises the dilemma of whether the pharmacokinetic differences in obese patients necessitate chemotherapy dosage adjustments. This also poses the question of whether obese patients experience differing outcomes or toxicities with chemotherapy. Objective We are retrospectively evaluating the association between percentage of ideal body weight (IBW) and complete remission (CR) among newly diagnosed, previously untreated AML patients. We also describe secondary objectives including associations between IBW and overall survival (OS), platelet and neutrophil recovery, and incidence of grade 3-4 hematologic and nonhematologic toxic effects. Additionally, we characterize the dosing strategies used for induction chemotherapy in obese patients with AML at a single institution. Methods This is a retrospective study of obesity and its impact on outcome in 63 newly diagnosed, previously untreated adults with AML receiving standard induction chemotherapy with 7 + 3 from 2006 to 2010. Results The median percentage of ideal body weight was 121% (range 86-246%). Thirty-five percent of patients were obese (≥ 130% IBW). Controlling for history of prior malignancies, FLT3-ITD status, and NPM1, obesity was not associated with CR (odds ratio [OR] = 0.97, p=0.88), OS (hazard ratio=0.48, p=0.52), platelet recovery by 30 days (OR=1.14, p=0.52), or neutrophil recovery by 30 days (OR=1.12, p=0.60). Among obese patients, CR rates were not significantly different comparing patients not dose adjusted to patients with obesity-related adjustments (CR=86% vs. 67%, p=0.55) Conclusion In this study population, obesity was not an independent prognostic factor of outcome or toxicity. Empiric dose reductions based on obesity did not result is significantly

  8. Role of the cell surface in selection during transport of proteins from mother to foetus and newly born.

    PubMed

    Wild, A E

    1975-07-17

    The transport of immunoglobulins from mother to foetus and newly born mammal involves selective events which are independent of molecular size, related to immunoglobulin class, structure, and species of origin, and involve considerable protein degradation. Such events are briefly described as background information to a discussion of how selection of proteins might take place during transport across the cellular barriers concerned, namely the yolk sac splanchnopleur, chorio-allantoic placenta, and small intesting. Until recently the Brambell hypothesis has been the most favoured explanation. This implies that selection occurs intracellularly, within endodermal cells of the yolk sac splanchnopleur and small intestine, and within the syncytiotrophoblast of the chorio-allantoic placenta, of certain species. It also suggests that specific receptors are present which give attached proteins protection from degradation when the vesicles containing them fuse with lysosomes; such protected proteins are then liberated from the vesicle by exocytosis. This hypothesis is examined in the light of what is now known about the mechanism of uptake and transport of proteins by the endodermal cells and syncytiotrophoblast. It is suggested that rather than being an intracellular event, involving protection from proteolytic degradation, selection takes place at the cell surface. Evidence is presented, some direct and some circumstantial, that proteins may be selectively endocytosed by coated micropinocytotic vesicles, and non-selectively endocytosed through a complex apical canalicular system leading to macropinocytotic vesicle formation. In the small intesting of the suckling rat these two processes appear to be segregated, selective uptake occurring in the proximal half and non-selective uptake occurring in the distal half. In the endodermal cells of the rabbit yolk sac splanchnopleur, and by implication in the syncytiotrophoblast of man and monkey, it is suggested that both selective

  9. ‘BRICS without straw’? A systematic literature review of newly emerging economies’ influence in global health

    PubMed Central

    2013-01-01

    Background Since 2010, five newly emerging economies collectively known as ‘BRICS’ (Brazil, India, Russia, China and South Africa) have caught the imagination, and scholarly attention, of political scientists, economists and development specialists. The prospect of a unified geopolitical bloc, consciously seeking to re-frame international (and global) health development with a new set of ideas and values, has also, if belatedly, begun to attract the attention of the global health community. But what influence, if any, do the BRICS wield in global health, and, if they do wield influence, how has that influence been conceptualized and recorded in the literature? Methods We conducted a systematic literature review in (March-December 2012) of documents retrieved from the databases EMBASE, PubMed/Medline, Global Health, and Google Scholar, and the websites of relevant international organisations, research institutions and philanthropic organisations. The results were synthesised using a framework of influence developed for the review from the political science literature. Results Our initial search of databases and websites yielded 887 documents. Exclusion criteria narrowed the number of documents to 71 journal articles and 23 reports. Two researchers using an agreed set of inclusion criteria independently screened the 94 documents, leaving just 7 documents. We found just one document that provided sustained analysis of the BRICS’ collective influence; the overwhelming tendency was to describe individual BRICS countries influence. Although influence was predominantly framed by BRICS countries’ material capability, there were examples of institutional and ideational influence - particularly from Brazil. Individual BRICS countries were primarily ‘opportunity seekers’ and region mobilisers but with potential to become ‘issue leaders’ and region organisers. Conclusion Though small in number, the written output on BRICS influence in global health has

    Objective: To investigate the relationship between low-grade inflammation (LI) and increased arterial stiffness in Chinese youth and adolescents with newly-diagnosed type 2 diabetes mellitus (T2DM). Methods: Ninety-eight subjects aged 10 to 24 years with newly-diagnosed T2DM were investigated for findings of general inflammation. Anthropometric measurements were taken. Data related to arterial stiffness [brachial artery distensibility (Branch D), augmentation index (AIx), carotid-femoral pulse wave velocity (CF-PWV)] were collected. The subjects were divided into a non-LI group (NLI, n=42) and a LI group (n=56) according to their high-sensitivity C-reactive protein (Hs-CRP) levels. Results: There were no significant differences in age and gender between the LI group and the NLI group. CF-PWV and AIx values of the LI group were higher than those of the NLI group (p<0.01), while Branch D values were lower in the LI group (p<0.01). Branch D, CF-PWV, and AIx values correlated significantly with Hs-CRP overall (r=-0.32, 0.34, 0.33, all p<0.01). Multivariate models revealed that in either group (LI or NLI), Hs-CRP, as a continuous variable, was an independent determinant of arterial stiffness parameters even after adjusting for other risk factors. Conclusion: Newly-diagnosed T2DM youth and adolescents with LI present a more adverse cardiovascular disease risk profile and stiffer arteries. Hs-CRP levels correlated with arterial stiffness parameters and constituted an independent determinant of arterial stiffness. PMID:26777037

    Abstract The overall survival of patients with multiple myeloma (MM) has been improved greatly over the last 2 decades with the broader use of novel drugs and autologous tandem transplantation. However, more than one tenth of myeloma patients still die shortly after diagnosis. We therefore aim to investigate the risk factors of early mortality (death within 60 days after diagnosis) in patients with MM. We included in this study 451 consecutive patients with MM, newly diagnosed at an Asian tertiary medical center between January 1, 2002 and April 30, 2015. A total of 57 subjects who experienced early mortality were identified. Risk factors for early mortality in myeloma patients were collected and analyzed. Early mortality occurred in 57 (12.6%) of the myeloma patients. In the multivariate analysis, being male (adjusted OR 2.93, 95% CI 1.17–7.31), serum albumin < 3.5 g/dL (adjusted OR 2.71, 95% CI 1.09–6.74), primary plasma cell leukemia (adjusted OR 17.61, 95% CI 1.01–306.05), serum albumin (adjusted OR 2.70, 95% CI 1.15–6.38), corrected serum calcium ≥ 12 mg/dL (adjusted OR 2.94, 95% CI 1.21–7.14), and LDH ≥ 250 U/L (adjusted OR 3.07, 95% CI 1.50–6.27) were identified as independent risk factors of early mortality. Pneumonia with other infections contributed most to early mortality (n = 36, 65%), followed by renal failure and cardiac failure. The early mortality rate is high (12.6%) in patients with MM. Patients who are male and those with primary plasma cell leukemia, low serum albumin, high-corrected serum calcium, or LDH are at risk of early mortality. Nearly two thirds of the myeloma patients who experienced early mortality in our study (37 of 57, 65%) died of infection. Once a high-risk group is identified, much effort is required to target new approaches for prevention, early detection, and treatment of infections. PMID:26683968

    It has recently become clear that many invasive species have evolved in situ via hybridization or polyploidy from progenitors which themselves are introduced species. For species formed by hybridization or polyploidy, genetic diversity within the newly formed species is influenced by the number of independent evolutionary origins of the species. For recently formed species, an analysis of genetic structure can provide insight into the number of independent origin events involved in the formation of the species. For a putative invasive allopolyploid species, the number of origins involved in the species formation, the genetic diversity present within these origins, and the level of gene flow between independent origins determines the genetic composition of the neospecies. Here we analyze the genetic structure of the newly formed allopolyploid species, Salsola ryanii, a tumbleweed which evolved within the last 20-100 years in California. We utilize the genetic structure analysis to determine that this new species is the result of at least three independent allopolyplodization events followed by gene flow between the descendants of independent origins.

    With the aggressive stance taken by the IRS regarding worker classification, many organizations may be risking significant retroactive assessments with respect to the use of independent contractors. Employers should be aware of the 20 primary factors considered by the IRS when examining independent contractor relationships and prepare in advance for IRS classification review or audit.

    It seems obvious that learning should not stop when independent work begins. In too many cases, however, the tasks and the thinking required to complete independent assignments are limited to regurgitating knowledge. The work itself does not move students' learning forward. Students must master the procedural knowledge (the how) of applying…
