  6. Determining the relative importance of figures in journal articles to find representative images

    2013-03-01

    When physicians are searching for articles in the medical literature, images of the articles can help determining relevance of the article content for a specific information need. The visual image representation can be an advantage in effectiveness (quality of found articles) and also in efficiency (speed of determining relevance or irrelevance) as many articles can likely be excluded much quicker by looking at a few representative images. In domains such as medical information retrieval, allowing to determine relevance quickly and accurately is an important criterion. This becomes even more important when small interfaces are used as it is frequently the case on mobile phones and tablets to access scientific data whenever information needs arise. In scientific articles many figures are used and particularly in the biomedical literature only a subset may be relevant for determining the relevance of a specific article to an information need. In many cases clinical images can be seen as more important for visual appearance than graphs or histograms that require looking at the context for interpretation. To get a clearer idea of image relevance in articles, a user test with a physician was performed who classified images of biomedical research articles into categories of importance that can subsequently be used to evaluate algorithms that automatically select images as representative examples. The manual sorting of images of 50 journal articles of BioMedCentral with each containing more than 8 figures by importance also allows to derive several rules that determine how to choose images and how to develop algorithms for choosing the most representative images of specific texts. This article describes the user tests and can be a first important step to evaluate automatic tools to select representative images for representing articles and potentially also images in other contexts, for example when representing patient records or other medical concepts when selecting

    With the increase in global transportation, imported malaria has become a significant public health concern in Japan. In the present study, we retrospectively analyzed all imported malaria cases in Okinawa Prefecture from 1988 to 2012. In that period, 23 patients with imported malaria were admitted to the University of the Ryukyus Hospital. Malaria types observed included Plasmodium falciparum (14 cases), P. vivax (7 cases), combined P. falciparum and P. ovale (1 case), and combined P. vivax and P. malariae (1 case). All cases were resolved by anti-malarial treatment. The clinical data from these patients highlights the importance of collecting patient travel history and ensuring an adequate supply of both diagnostic test and drug treatments in Okinawa.

    Suspected dengue cases in Japan during the period of 1985-1995, 173 cases with unknown febrile illness entering or returning from mostly southeast Asia, were tested by serology and RT-PCR gene amplification. Seventy seven cases were confirmed by a significant rise of dengue 2 (Den 2) HI antibody in paired sera or by detection of HI antibody titer higher than 1:320 in single serum. The other 3 cases with antibody levels not higher than 1:80 in paired sera and 12 cases with an antibody 1:160 in single sera were positively suspected of dengue infection but were not confirmed. Countries of origin of confirmed cases were Thailand (39 cases), Philippinse (15), India (13), and Indonesia (9). Sera of dengue cases showed high degrees of cross reactivity of Japanese encephalitis virus (JEV) in HI test but not in IgM capture ELISA. Sera of confirmed JEV-infected cases, however, showed practically no cross reactivity to Den 1 4 in HI test, suggesting unilateral cross reactivity of HI antibody. RT-PCR detected the Den 1 genome in sera of 3 cases obtained within 3 days after onset and the Den 2 genome in serum of case 4 days after onset. Although the number is limited, 92 (53%) out of 173 cases of febrile illness of unknown etiology entering Japan from tropical countries were either confirmed or positively suspected to be dengue fever. Considering possibilities of under reporting, importations of tropical viral infections should be bigger in number and will necessitate our intensified alertness.

    The comparative analysis of the cases of imported malaria in Lombardy and in Italy during 1976-1980, shows that the prevalent factors of risk are, in both, the male sex, the young age, the stay in endemic areas of tropical Africa where P. falciparum is greatly prevalent. The only very significant difference is represented by the prevalence of touristic motivation of the stay among the cases of Lombardy. The efficacy of prophylaxis against these factors of risk allowed to note, in the two last years considered (1979-1980), a sharp reduction of the annual number of cases in opposition to the trend of European cases of malaria.

    Clinical neuropsychologists accept more forensic referrals now and spend more time in forensic consulting than ever before. Recent surveys show weekly hours devoted to forensic consulting increased 97% in the past decade. During the same time period, the number of board certified neuropsychologists more than doubled. Under recently published Specialty Guidelines for Forensic Psychology, clinical neuropsychologists practice forensic psychology when applying scientific, technical, or specialized knowledge of neuropsychology to the law to assist in addressing legal, contractual, or administrative matters. Among those increasingly varied forensic referrals, clinical neuropsychologists are conducting more civil competency and capacity evaluations. Representative cases from three jurisdictions demonstrate how neuropsychologists provide expertize in matters involving testamentary capacity, contractual capacity, business judgments, and job capacity. Case presentations illustrate some of the strengths and weaknesses of neuropsychological evaluation of civil capacities. The article concludes with a "battle of experts" case involving five neuropsychologists with opposing opinions recently heard in a Federal Appellate court. Implications for neuropschology training and forensic competencies are considered. In offering quality services to the legal profession, neuropsychologists support the truth-seeking function of the judiciary, promote justice, protect the profession, and serve public policy.

    Tungiasis is an endemic disease in many resource-poor communities some of which are in South America, which are visited frequently by Spanish travelers. Its diagnosis can be improved with the knowledge of the typical presentation and the correct management of its injuries. We report the first four cases identified of imported tungiasis in Mallorca. All four patients visited beaches in Brazil and presented the classical black lesions after their return. Two of the patients were diagnosed at primary care level and all were treated by dermatologists with surgical techniques. Dermoscopy was used for the initial approach to the injuries. Tungiasis can be suspected easily by examining carefully the black lesions and asking about previous travel. It can be treated readily by minor surgical techniques. PMID:21530410

    A case of overseas imported quartan malaria was reported in Weihai City. The patient worked in Africa for many years, had no blood transfusion history, and had not been to malaria endemic regions of China. In approximately half a month after returning from Africa, the patient appeared suspected malaria symptoms, such as irregular fever, sweating, and headache. The patient was diagnosed as quartan malaria by a blood test in basic hospital, reviewed with a microscope by Weihai Centre for Disease Control and Prevention, and checked through the microscopic examination of malaria diagnosis and reference laboratory and PCR amplification by Shandong Institute of Parasitic Diseases. The patient was cured after the treatment with chloroquine/ primaquine for 8 days, and did not recur in the 3-month following up. PMID:26510375

    The local ecological footprinting tool (LEFT) uses globally available databases, modeling, and algorithms to, remotely assess locally important ecological features across landscapes based on five criteria: biodiversity (beta-diversity), vulnerability (threatened species), fragmentation, connectivity, and resilience. This approach can be applied to terrestrial landscapes at a 300-m resolution within a given target area. Input is minimal (latitude and longitude) and output is a computer-generated report and series of maps that both individually and synthetically depict the relative value of each ecological criteria. A key question for any such tool, however, is how representative is the remotely obtained output compared to what is on the ground. Here, we present the results from comparing remotely- vs. field-generated outputs from the LEFT tool on two distinct study areas for beta-diversity and distribution of threatened species (vulnerability), the two fields computed by LEFT for which such an approach is feasible. The comparison method consists of a multivariate measure of similarity between two fields based on discrete wavelet transforms, and reveals consistent agreement across a wide range of spatial scales. These results suggest that remote assessment tools such as LEFT hold great potential for determining key ecological features across landscapes and for being utilized in preplanning biodiversity assessment tools.

  15. Representing ozone extremes in European megacities: the importance of resolution in a global chemistry climate model

    2014-04-01

    The continuing growth of the world's urban population has led to an increasing number of cities with more than 10 million inhabitants. The higher emissions of pollutants, coupled to higher population density, makes predictions of air quality in these megacities of particular importance from both a science and a policy perspective. Global climate models are typically run at coarse resolution to enable both the efficient running of long time integrations, and the ability to run multiple future climate scenarios. However, when considering surface ozone concentrations at the local scale, coarse resolution can lead to inaccuracies arising from the highly nonlinear ozone chemistry and the sensitivity of ozone to the distribution of its precursors on smaller scales. In this study, we use UM-UKCA, a global atmospheric chemistry model, coupled to the UK Met Office Unified Model, to investigate the impact of model resolution on tropospheric ozone, ranging from global to local scales. We focus on the model's ability to represent the probability of high ozone concentrations in the summer and low ozone concentrations, associated with polluted megacity environments, in the winter, and how this varies with horizontal resolution. We perform time-slice integrations with two model configurations at typical climate resolution (CR, ~150 km) and at a higher resolution (HR, ~40 km). The CR configuration leads to overestimation of ozone concentrations on both regional and local scales, while it gives broadly similar results to the HR configuration on the global scale. The HR configuration is found to produce a more realistic diurnal cycle of ozone concentrations and to give a better representation of the probability density function of ozone values in urban areas such as the megacities of London and Paris. We find the observed differences in model behaviour between CR and HR configurations to be largely caused by chemical differences during the winter and meteorological differences

    Neurocysticercosis (NCC) is the most common cause of acquired epilepsy in resource-poor countries. We report the case of a 24-year-old woman born and residing in Guinea-Bissau, who was transferred to Portugal two months after the onset of a possible meningitis (fever, headache, seizures, and coma) that did not respond to antibiotic treatment. The diagnosis of NCC was confirmed by MR imaging, which showed multiple lesions compatible with cysticercus, and by polymerase chain reaction (PCR) of the cerebrospinal fluid. After 28 days on albendazole and dexamethasone without improvement, she was started on praziquantel, which she completed in six weeks with progressive recovery.

  4. Importance of representing optical depth variability for estimates of global line-shaped contrail radiative forcing

    PubMed Central

    Kärcher, Bernd; Burkhardt, Ulrike; Ponater, Michael; Frömming, Christine

    2010-01-01

    Estimates of the global radiative forcing by line-shaped contrails differ mainly due to the large uncertainty in contrail optical depth. Most contrails are optically thin so that their radiative forcing is roughly proportional to their optical depth and increases with contrail coverage. In recent assessments, the best estimate of mean contrail radiative forcing was significantly reduced, because global climate model simulations pointed at lower optical depth values than earlier studies. We revise these estimates by comparing the probability distribution of contrail optical depth diagnosed with a climate model with the distribution derived from a microphysical, cloud-scale model constrained by satellite observations over the United States. By assuming that the optical depth distribution from the cloud model is more realistic than that from the climate model, and by taking the difference between the observed and simulated optical depth over the United States as globally representative, we quantify uncertainties in the climate model’s diagnostic contrail parameterization. Revising the climate model results accordingly increases the global mean radiative forcing estimate for line-shaped contrails by a factor of 3.3, from 3.5 mW/m2 to 11.6 mW/m2 for the year 1992. Furthermore, the satellite observations and the cloud model point at higher global mean optical depth of detectable contrails than often assumed in radiative transfer (off-line) studies. Therefore, we correct estimates of contrail radiative forcing from off-line studies as well. We suggest that the global net radiative forcing of line-shaped persistent contrails is in the range 8–20 mW/m2 for the air traffic in the year 2000. PMID:20974909

    Chikungunya (CHIK), a newly recognized mosquito-borne disease in the Western Hemisphere, has resulted in well over a million cases since December 2013. Only about a dozen locally-acquired cases thus far have been reported in the U. S. (Florida), but approximately 1500 imported cases have been seen in returning travelers from the Caribbean and Central and South America. Public health officials are concerned that imported cases may lead to infection of local mosquitoes and, thus disease transmission. This paper documents 9 confirmed CHIK cases in Mississippi: 5 resulting from travel to the Dominican Republic, 2 from Haiti, 1 from Honduras, and 1 from Puerto Rico. In addition, the Mississippi State Department of Health response to those cases is presented and discussed.

    Coccidioidomycosis is a fungal disease found only in the Western Hemisphere. In recent years, the incidence of the disease has increased in California and Arizona, which may be partially due to the rapid immigration of previously unexposed persons from states outside the endemic areas. The disease in the nonendemic areas is usually imported. Determining a history of exposure is critical for performing the diagnosis of coccidioidomycosis in these cases. Histopathological examination is the key to the diagnosis when fungal culture and molecular studies are not available. We hereby report an imported case of cutaneous coccidioidomycosis, which to the best of our knowledge is the first case report from North India. PMID:25071284

    2013-01-01

    Sixty cases of human rabies in international travelers were reviewed from 1990–2012. A significant proportion of the cases were observed in migrants or their descendants when emigrating from their country of origin or after a trip to visit friends and relatives or for other reasons (43.3%). The cases were not necessarily associated with long-term travel or expatriation to endemic countries; moreover, cases were observed in travelers after short trips of two weeks or less. A predominance of male patients was observed (75.0%). The proportion of children was low (11.7%). Cases from India and Philippines were frequent (16 cases/60). In a significant proportion of cases (51.1%), diagnosis was challenging, with multiple missed diagnoses and transfers from ward to ward before the final diagnosis of rabies. Among the 28 patients whose confirmed diagnosis was obtained ante-mortem, the mean time between hospitalization and diagnosis was 7.7 days (median time: 6.0 days, range 2–30) including four cases with a diagnosis delayed by 15 or more days. In five cases, a patient traveled through one or more countries before ultimately being hospitalized. Three factors played a role in delaying the diagnosis of rabies in a number of cases: (i) a low index of suspicion for rabies in countries where the disease has been eradicated for a long time or is now rare, (ii) a negative history of animal bites or exposure to rabies, and (iii) atypical clinical presentation of the disease. Clinical symptomatology of rabies is complex and commonly confuses physicians. Furthermore, failure in diagnosing imported cases in more developed countries is most likely related to the lack of medical familiarity with even the typical clinical features of the disease.

    During the current outbreak of Ebola virus disease (EVD) in West Africa, preventing exportation of the disease posed many challenges for economically more developed countries. In Israel, although the risk of importing single cases was assumed to be low, the implications of local transmission were great. This article describes the EVD preparedness plan of the Israeli Ministry of Health. Key elements were a sensitive case definition, designation of a single treatment centre for suspected and confirmed cases, construction of a mobile unit using customised negative-pressure tents and a vigorous national training programme. There were no patients with EVD in Israel, but a few suspected cases were assessed. The Israeli plan may provide a template for emergency infectious disease response in other geographically small countries.

    Since Zika virus has been spreading rapidly in the Americas from 2015, the outbreak of Zika virus infection becomes a global health emergency because it can cause neurological complications and adverse fetal outcome including microcephaly. Here, we report clinical manifestations and virus isolation findings from a case of Zika virus infection imported from Brazil. The patient, 43-year-old Korean man, developed fever, myalgia, eyeball pain, and maculopapular rash, but not neurological manifestations. Zika virus was isolated from his semen, and reverse-transcriptase PCR was positive for the virus in the blood, urine, and saliva on the 7th day of the illness but was negative on the 21st day. He recovered spontaneously without any neurological complications. He is the first case of Zika virus infection in Korea imported from Brazil.

  19. The importance of actions and the worth of an object: dissociable neural systems representing core value and economic value

    Coppin, Géraldine; Schwartz, Sophie; Sander, David

    2012-01-01

    Neuroeconomic research has delineated neural regions involved in the computation of value, referring to a currency for concrete choices and decisions (‘economic value’). Research in psychology and sociology, on the other hand, uses the term ‘value’ to describe motivational constructs that guide choices and behaviors across situations (‘core value’). As a first step towards an integration of these literatures, we compared the neural regions computing economic value and core value. Replicating previous work, economic value computations activated a network centered on medial orbitofrontal cortex. Core value computations activated medial prefrontal cortex, a region involved in the processing of self-relevant information and dorsal striatum, involved in action selection. Core value ratings correlated with activity in precuneus and anterior prefrontal cortex, potentially reflecting the degree to which a core value is perceived as internalized part of one’s self-concept. Distributed activation pattern in insula and ACC allowed differentiating individual core value types. These patterns may represent evaluation profiles reflecting prototypical fundamental concerns expressed in the core value types. Our findings suggest mechanisms by which core values, as motivationally important long-term goals anchored in the self-schema, may have the behavioral power to drive decisions and behaviors in the absence of immediately rewarding behavioral options.

    Chikungunya is caused by an arbovirus transmitted by Aedes mosquito vector. With the increase of habitat of mosquito by global warming and frequent international travel and interchange, chikungunya reemerged and showed global distribution recently. Until now there has not been reported any case infected with chikungunya virus in Korea. A 23-year-old man has been the Republic of the Philippines for 1 week, and visited our emergency center due to fever and back pain. Chikungunya viral infection was diagnosed by specific IgM for chickungunya virus by enzyme-linked immunosorbent assayin Korea Centers for Disease Control and Prevention. His clinical course was self limited. We introduce the first imported case infected with chikungunya virus in Korea. PMID:25844264

    We report the first case of an imported Plasmodium ovale relapse in a Tunisian man who developed malaria three years after leaving sub- Saharan Africa. A 29-year-old Tunisian man consulted in September 2011 because of a fever, myalgia, and headache that had begun eight days earlier and persisted despite treatment with oral antibiotics. On questioning, the patient stated that he had resided three years ago for six months in Ivory Coast, where he acquired malaria. He was treated with artemether-lumefantrine. The patient said he had no recent travel to any other malaria-endemic area and had not received a blood transfusion. A first microscopy of peripheral blood smears was negative for malaria parasites. The diagnosis was established 17 days after onset of symptoms. A repeat microscopic examination of blood smears confirmed the presence of Plasmodium ovale with a parasitemia lower than 0.1%. The patient was treated with artemether lumefantrine, followed by primaquine. This case emphasizes the possibility of relapse of some plasmodial species. It highlights the importance of repeating microscopic examination of blood when the diagnosis of malaria is suspected. PMID:26644094

    Soft tissue sarcomas (STS) are rare and heterogeneous tumours representing approximately 0.7%-1% of all adult tumours. In the adults and among the retroperitoneal sarcomas (RPS), Liposarcoma (LS) is the most common variant accounting for 12% -20% of all sarcomas and up to 45% of sarcomas at retroperitoneal localization. A rare case of LS relapsed after 15 years is giving the occasion to review the published literature and emphasise the followings concepts: 1) Despite extensive surgery remains the mainstay of treatment for localized STS at present, anatomical complexity and occult localization result in local recurrence in the majority of patients; 2) The role of imaging and tumour markers is still limited; 3) Indefinite prolonged surveillance is a key point of treatment; 4) Referral to tertiary centres with dedicated Retroperitonal Surgeons and Oncology expertise is mandatory.

    Among Plasmodium species the causative agent of malaria in Turkey is P.vivax, however the incidence of imported falciparum malaria cases is steadily increasing. P.falciparum may cause severe malaria with the involvement of central nervous system, acute renal failure, severe anemia or acute respiratory distress syndrome. Furhermore most of the casualties due to malaria are related with P.falciparum. There is recently, a considerable increase in malaria infections especially in tropical areas. In this report, three cases, who have admitted to our hospital with three different clinical presentations of falciparum malaria, and all shared common history of travelling to Africa were presented. First case was a 27 years old, male patient who returned from Malawi seven days ago where he stayed for two weeks. He admitted to our hospital with the complaints of sensation of cold, shivering and fever. In physical examination his body temperature was 37.9°C, C-reactive protein level was high, and the other systemic results were normal. The second case was a 25 years old, male patient who returned from Gambia two weeks ago. He was suffering from fever, headache, shivering and unable to maintain his balance. The patient's body temperature was 38°C. Laboratory tests revealed hyperbilirubinemia and thrombocytopenia. Parasitological examination of the Giemsa-stained peripheral blood smear of these two patients demonstrated ring forms compatible with P.falciparum. Treatment was commenced with arthemeter plus lumefantrine, resulting with complete cure. Third case was a 46 years old, male patient who had been working in Uganda, and returned to Turkey two weeks ago. He had sudden onset of fever, headache, nausea and vomiting and impaired consciousness. His peripheral blood smear revealed ring-formed trophozoites and banana-shaped gametocytes of P.falciparum. Arthemeter plus lumefantrine therapy was started, however, he developed severe thrombocytopenia and jaundice under treatment

  4. Imported water risk: the case of the UK

    While the water dependency of water-scarce nations is well understood, this is not the case for countries in temperate and humid climates, even though various studies have shown that many of such countries strongly rely on the import of water-intensive commodities from elsewhere. In this study we introduce a method to evaluate the sustainability and efficiency of the external water footprint (WF) of a country, with the UK as an example. We trace, quantify and map the UK’s direct and indirect water needs and assess the ‘imported water risk’ by evaluating the sustainability of the water consumption in the source regions. In addition, we assess the efficiency of the water consumption in source areas in order to identify the room for water savings. We find that half of the UK’s global blue WF—the direct and indirect consumption of ground- and surface water resources behind all commodities consumed in the UK—is located in places where the blue WF exceeds the maximum sustainable blue WF. About 55% of the unsustainable part of the UK’s blue WF is located in six countries: Spain (14%), USA (11%), Pakistan (10%), India (7%), Iran (6%), and South Africa (6%). Our analysis further shows that about half of the global consumptive WF of the UK’s direct and indirect crop consumption is inefficient, which means that consumptive WFs exceed specified WF benchmark levels. About 37% of the inefficient part of the UK’s consumptive WF is located in six countries: Indonesia (7%), Ghana (7%), India (7%), Brazil (6%), Spain (5%), and Argentina (5%). In some source countries, like Pakistan, Iran, Spain, USA and Egypt, unsustainable and inefficient blue water consumption coincide. We find that, by lowering overall consumptive WFs to benchmark levels, the global blue WF of UK crop consumption could be reduced by 19%. We discuss four strategies to mitigate imported water risk: become more self-sufficient in food; diversify the import of water-intensive commodities, favouring

    The foundation of firearm and tool mark identification is that no two tools should produce the same microscopic marks on two separate objects that they would be inaccurately or wrongly identified. Studies addressing the validity of identification infrequently employ tests that mirror realistic casework scenarios. This study attempted to do so using a double-blind process, reducing test-taking bias. Test kits including bullets and cartridge cases but not the associated firearms were completed by 31 analysts from 22 agencies. Analysis of the results demonstrated an overall error rate of 0.303%, sensitivity of 85.2%, and specificity of 86.8%. Variability in performance across examiners is addressed, and the effect of examiners' years of experience on identification accuracy is explored. Finally, the article discusses the importance of studies using realistic case work scenarios when validating the field's performance and in providing courts with usable indicators of the accuracy of firearm and tool mark identification.

    Thirty eight patients with classic dengue fever, were studied from December 1999 up to April 2000. All of them acquired the infection in Paraguay; 66% of patients arrived at Buenos Aires metropolitan area within the viremia period. Given Aedes aegypti abundance in the region they represent a high risk for local transmission. Unusual clinical findings in these patients were diarrhea (29%), transitory rise of seric aspartate aminotransferase (52%) and pruritic rash in all cases. Only 15.7% showed a biphasic course and none of the five patients with hemorrhages had a positive loop test. These observations show that dengue fever could be misdiagnosed as gastroenteritis or flue-like illness. These patients remain at risk of suffering hemorrhagic dengue. DEN 1 has not been reported in Buenos Aires. This fact and the unusual number of imported cases, represent a serious public health problem.

    Objective Clinical studies demonstrate the efficacy of interventions to reduce neonatal deaths, but there are fewer studies of their real-life effectiveness. In India, women often seek facility delivery after complications arise, rather than to avoid complications. Our objective was to quantify the association of facility delivery and postnatal checkups with neonatal mortality while examining the “reverse causality” in which the mothers deliver at a health facility due to adverse perinatal events. Methods We conducted nationally representative case-control studies of about 300,000 live births and 4,000 neonatal deaths to examine the effect of, place of delivery and postnatal checkup on neonatal mortality. We compared neonatal deaths to all live births and to a subset of live births reporting excessive bleeding or obstructed labour that were more comparable to cases in seeking care. Findings In the larger study of 2004–8 births, facility delivery without postnatal checkup was associated with an increased odds of neonatal death (Odds ratio = 2.5; 99% CI 2.2–2.9), especially for early versus late neonatal deaths. However, use of more comparable controls showed marked attenuation (Odds ratio = 0.5; 0.4–0.5). Facility delivery with postnatal checkup was associated with reduced odds of neonatal death. Excess risks were attenuated in the earlier study of 2001–4 births. Conclusion The combined effect of facility deliveries with postnatal checks ups is substantially higher than just facility delivery alone. Evaluation of the real-life effectiveness of interventions to reduce child and maternal deaths need to consider reverse causality. If these associations are causal, facility delivery with postnatal check up could avoid about 1/3 of all neonatal deaths in India (~100,000/year). PMID:26479476

    Emissions of biogenic volatile organic compounds (VOCs) form an important part of the global carbon cycle, comprising a significant proportion of net ecosystem productivity. They impact atmospheric chemistry and contribute directly and indirectly to greenhouse gases. Isoprene, emitted largely from plants, comprises one third of total VOCs, yet in contrast to methane, which is released in similar quantities, we know little of its biodegradation. Here, we report the genome of an isoprene degrading isolate, Rhodococcus sp. AD45, and, using mutagenesis shows that a plasmid-encoded soluble di-iron centre isoprene monooxygenase (IsoMO) is essential for isoprene metabolism. Using RNA sequencing (RNAseq) to analyse cells exposed to isoprene or epoxyisoprene in a substrate-switch time-course experiment, we show that transcripts from 22 contiguous genes, including those encoding IsoMO, were highly upregulated, becoming among the most abundant in the cell and comprising over 25% of the entire transcriptome. Analysis of gene transcription in the wild type and an IsoMO-disrupted mutant strain showed that epoxyisoprene, or a subsequent product of isoprene metabolism, rather than isoprene itself, was the inducing molecule. We provide a foundation of molecular data for future research on the environmental biological consumption of this important, climate-active compound. PMID:25727256

    2014-01-01

    Background With the aim of eliminating malaria from Sri Lanka by 2014, the Anti-Malaria Campaign of Sri Lanka (AMC) sought the support of Tropical and Environmental Disease and Health Associates Private Limited (TEDHA), a private sector organization. In 2009, TEDHA was assigned 43 government hospitals in the district of Mannar in the Northern Province and in districts of Trincomalee, Batticaloa and Ampara in the Eastern Province to carry out malaria surveillance to complement the surveillance activities of the AMC. Passive case detection (PCD), activated passive case detection (APCD) and active case detection (ACD) for malaria have been routinely carried out in Sri Lanka. Methods The active case detection programme of TEDHA involves screening of populations irrespective of the presence of fever or any other signs or symptoms of malaria to detect infections and residual parasite carriers. ACD is done by TEDHA in a) high risk populations through mobile malaria clinics including armed forces personnel and b) pregnant females who visit antenatal clinics for asymptomatic malaria infections during the first trimester of pregnancy. Populations are selected in consultation with the Regional Malaria Officer of the AMC thus avoiding any overlap with the population screened by the government. Results TEDHA screened 387,309 individuals in the four districts for malaria by ACD including high risk groups and pregnant women between January 2010 and December 2012. During this period seven individuals were diagnosed with Plasmodium vivax infections and one individual was detected with a mixed infection of P. vivax and Plasmodium falciparum. All eight cases were detected by ACD carried out by mobile malaria clinics among high risk groups in the Mannar district. Conclusion The progress made by Sri Lanka in the malaria elimination drive is largely due to increased surveillance and judicious use of control methods which has resulted in zero indigenous malaria cases being reported since

    Disease-related malnutrition is usually caused by the joint action of the underlying disease itself and dietary deficiency. The consequences of malnutrition, if left untreated, are serious, causing a marked decline in physical and psychological health and function, and an increased rate of complications and decreased effectiveness of the medical treatments. In case a functional gastrointestinal tract is present, the recommended form of nutritional management is the use of oral nutritional supplements. However, just like to any other therapy, compliance to oral nutritional supplements is highly influenced by the consistency, taste, smell, volume consumed, and side effects. The aim of the present case report is to illustrate that nutritional management is a successful and effective treatment option of disease-related malnutrition when the selection of the oral nutritional supplement takes into consideration patient's preferences as well.

    Malaria is a notifiable disease in Australia with an average of 600 notifications per year in returned travellers or newly arrived refugees, migrants and visitors. Although endemic disease has been eliminated from the tropical north of Australia, the region remains malaria receptive due to the presence of efficient mosquito vectors. This study analyses enhanced surveillance data collected by the Centre for Disease Control on all cases of malaria notified in the Northern Territory from 1 January 2000 to 31 December 2010. There were 428 malaria episodes notified that occurred in 391 individuals with a median age of 26 years. Of these, 71.4% were male, 40.5% were Australian nationals and 38.0% were prescribed chemoprophylaxis. Primary infection consisted of 196 (51.3%) cases of Plasmodium falciparum, 165 (43.2%) P. vivax, 2 (0.5%) P. ovale, 1 (0.3%) P. malariae and 18 were mixed infections. There were 46 episodes of relapsed infection. Residents of non-malarious countries were most likely to have acquired primary infection in East Timor (40.6%), Papua New Guinea (27.8%), Indonesia (18.7%) and Africa (6.4%). Primary infection was diagnosed after a median 19 days (interquartile range (IQR) 7-69) after arrival in Australia for cases of P. vivax compared with 4 days for P. falciparum (IQR 2-11). Screening protocols led to the diagnosis of 27.2% of cases. Eighty-seven per cent of patients were admitted to hospital at the time of their malaria diagnosis with median duration of 3 days (IQR 2-4) and one patient died. Resettlement of people from endemic countries, as well as military and civilian activities, influences the prevailing notification rates and Plasmodium species type. PMID:23153087

    Bovine besnoitiosis is an economically important disease of cattle, caused by Besnoitia besnoiti (Protozoa, Apicomplexa). A considerable spreading of this parasitic infection has been observed in Europe in the last ten years, mainly related to animal trade. In order to investigate the possibility of B. besnoiti being unnoticed introduced and getting established in Switzerland through the import of breeding cattle from France, a total of 767 animals (650 cattle imported from France and 117 cattle that had contact with B. besnoiti positive cattle in Swiss farms) were screened for antibodies against B. besnoiti by both a commercial ELISA and by the indirect fluorescent antibody test (IFAT). A total of 101 (13.17%) samples showed a positive reaction in ELISA (cut-off: percent of positivity [PP] ≥ 15) and 16 (2.09%) samples had IFAT titers ≥ 1:100. Eight of those samples reacted positive in Western blot (WB), corresponding to five imported Limousin cattle (two cows and one bull from France and two cows from Germany) and to three cattle born in Switzerland (one Limousin heifer born from one of the positive German cows, and two adult Braunvieh cows, that had been in contact with one of the French cows at a Swiss farm). Seven of those animals were subclinically infected and one animal showed only very mild signs. They were subsequently slaughtered, and the serological diagnosis could be confirmed by real-time PCR and/or histopathology in seven animals. The most frequent parasite localizations were the tendons and surrounding connective tissue of the distal limbs and the skin of the head region. Furthermore, B. besnoiti could be successfully isolated in vitro from one French, one German and one Swiss cattle (isolates Bb-IPZ-1-CH, Bb-IPZ-2-CH and Bb-IPZ-3-CH). In the current situation in Switzerland, prophylactic and control measures should include a serological examination of cattle to be imported from endemic areas and the culling of all confirmed positive animals from

    We report a previously well 10-month-old Somalian girl who acquired asymmetric lower limb weakness in July 2013 in Mogadishu, Banadir, before arriving in Malaysia at 12 months of age. In May 2013, there was a wild poliomyelitis outbreak in that area, as reported by the World Health Organization. Laboratory investigation, including cerebrospinal fluid, was unremarkable, and electrophysiological studies showed active axonal denervation in the left lower limb. The whole spine T2-weighted MRI revealed non-enhancing hyperintensities of the bilateral anterior horn cells, predominantly on the left side at T11-12. The viral isolations from two stool specimens at her presentation to our centre, 2 months after the onset of illness and 2 weeks apart, were negative. Despite lacking the acute virological evidence of poliomyelitis, in view of the girl's clinical, electrophysiological and classical spinal neuroradiological features, together with her temporal relationship with a World Health Organization reported wild poliomyelitis outbreak, we believe these findings are consistent with a diagnosis of imported poliomyelitis. A review at 30 months of age showed persistent left lower limb monoplegia with little recovery. Our patient reiterates the importance of maintaining awareness of wild polio importation, and keeping abreast of the latest news of global poliomyelitis outbreaks when treating patients with flaccid paralysis, even if they arrive from non-endemic poliomyelitis areas.

    We report a previously well 10-month-old Somalian girl who acquired asymmetric lower limb weakness in July 2013 in Mogadishu, Banadir, before arriving in Malaysia at 12 months of age. In May 2013, there was a wild poliomyelitis outbreak in that area, as reported by the World Health Organization. Laboratory investigation, including cerebrospinal fluid, was unremarkable, and electrophysiological studies showed active axonal denervation in the left lower limb. The whole spine T2-weighted MRI revealed non-enhancing hyperintensities of the bilateral anterior horn cells, predominantly on the left side at T11-12. The viral isolations from two stool specimens at her presentation to our centre, 2 months after the onset of illness and 2 weeks apart, were negative. Despite lacking the acute virological evidence of poliomyelitis, in view of the girl's clinical, electrophysiological and classical spinal neuroradiological features, together with her temporal relationship with a World Health Organization reported wild poliomyelitis outbreak, we believe these findings are consistent with a diagnosis of imported poliomyelitis. A review at 30 months of age showed persistent left lower limb monoplegia with little recovery. Our patient reiterates the importance of maintaining awareness of wild polio importation, and keeping abreast of the latest news of global poliomyelitis outbreaks when treating patients with flaccid paralysis, even if they arrive from non-endemic poliomyelitis areas.

    We report a case of Zika virus (ZIKV) infection in a patient with diarrhea, fever, synovitis, non-purulent conjunctivitis, and with discreet retro-orbital pain, after returning from Colombia in January 2016. The patient referred several mosquito bites. Presence of ZIKV was detected by PCR (polymerase chain reaction) in plasma. Rapid microbiological diagnosis of ZIKV infection is needed in European countries with circulation of its vector, in order to avoid autochthonous circulation. The recent association of ZIKV infection with abortion and microcephaly, and a Guillain-Barré syndrome highlights the need for laboratory differentiation of ZIKV from other virus infection. Women with potential risk for Zika virus infection who are pregnant or planning to become pregnant must mention that fact during prenatal visits in order to be evaluated and properly monitored.

    A Chikungunya virus (CHIKV) epidemic emerged in the Indian Ocean islands of the Comores, Reunion, Mayotte, Mauritius, the Seychelles and Madagascar in 2005 resulting in the infection of about 250.000 inhabitants and travellers in only one year. Beginning in March 2006 increasing numbers of CHIKV-like febrile illnesses were reported from various parts of India. We investigated 70 consecutive German travellers returning from the affected areas and presenting with arthralgia and/or fever suggestive of CHIKV infection. Eleven patients had serological evidence of CHIKV infection. Real-time RT-PCR for CHIKV was positive in two cases, one who returned from Mauritius and the other who came back from Rajasthan, Northern India. In both cases CHIKV was isolated and sequencing of the entire viral genome was performed. The nucleotide sequence data obtained for both CHIKV strains revealed a high level of identity to CHIKV isolates from the ongoing epidemic. In detail, we found only 18 nucleotide exchanges between the isolates from Mauritius and Rajasthan, resulting in only six amino acid changes (nsP1 T128K, T376M, nsP3 S472N, capsid P23S, V27I and E1-protein A226V). Although the excessive dimension of the 2005/2006 outbreak in the Indian Ocean islands was at least in part accounted to the naïve population affected, our results of the Rajasthan isolate support that the emergence of this CHIKV subtype may rather be a result of a better viral fitness. This has been previously accounted to a A226V change in the E1 protein of the new CHIKV variant when compared to other CHIKV data available. This mutation, supposedly resulting in high-titred viremia in humans and/or an enhanced adaptation to the vector population resulting in increased transmission rates, was also found in our CHIKV isolate from Mauritius. The spread of an African CHIKV to Asia further demonstrates how fast viruses can emerge and establish in places where competent vectors are prevalent.

    2014-06-01

    Background: The current rules in the nuclear section of the ASME Boiler and Pressure Vessel (B&PV) Code , Section III, Subsection NH for the evaluation of strain limits and creep-fatigue damage using simplified methods based on elastic analysis have been deemed inappropriate for Alloy 617 at temperatures above 1200F (650C)1. To address this issue, proposed code rules have been developed which are based on the use of elastic-perfectly plastic (E-PP) analysis methods and which are expected to be applicable to very high temperatures. The proposed rules for strain limits and creep-fatigue evaluation were initially documented in the technical literature 2, 3, and have been recently revised to incorporate comments and simplify their application. The revised code cases have been developed. Task Objectives: The goal of the Sample Problem task is to exercise these code cases through example problems to demonstrate their feasibility and, also, to identify potential corrections and improvements should problems be encountered. This will provide input to the development of technical background documents for consideration by the applicable B&PV committees considering these code cases for approval. This task has been performed by Hollinger and Pease of Becht Engineering Co., Inc., Nuclear Services Division and a report detailing the results of the E-PP analyses conducted on example problems per the procedures of the E-PP strain limits and creep-fatigue draft code cases is enclosed as Enclosure 1. Conclusions: The feasibility of the application of the E-PP code cases has been demonstrated through example problems that consist of realistic geometry (a nozzle attached to a semi-hemispheric shell with a circumferential weld) and load (pressure; pipe reaction load applied at the end of the nozzle, including axial and shear forces, bending and torsional moments; through-wall transient temperature gradient) and design and operating conditions (Levels A, B and C).

The two examples presented, one each for forestry and crops, represent what is probably the worst case'' for possible acidic rain effects on crops and forests. Both examples revolve around hypotheses centering on stress from acidic fogwater or cloudwater. Because it is likely that additional information will become available prior to the publication of the Integrated Assessment, it should be understood that the analyses and interpretations presented on the following pages are subject to change when NAPAP publishes its final Assessment in 1990. 76 refs., 3 tabs.

    Three very large, nationally representative samples of married couples were used to examine the relative importance of 3 types of personality effects on relationship and life satisfaction: actor effects, partner effects, and similarity effects. Using data sets from Australia (N = 5,278), the United Kingdom (N = 6,554), and Germany (N = 11,418) provided an opportunity to test whether effects replicated across samples. Actor effects accounted for approximately 6% of the variance in relationship satisfaction and between 10% and 15% of the variance in life satisfaction. Partner effects (which were largest for Agreeableness, Conscientiousness, and Emotional Stability) accounted for between 1% and 3% of the variance in relationship satisfaction and between 1% and 2% of the variance in life satisfaction. Couple similarity consistently explained less than .5% of the variance in life and relationship satisfaction after controlling for actor and partner effects.

    Agroecosystems have a very important role in the regional balance of greenhouse gases (GHG). However, the volume of existing data on the different crops and agrotechnologies influence on the GHG emission sharply varies. The European territory of Russia (ETR) is one of regions with strong deficit of this information. At the same time ETR is characterized by high heterogeneity of soil cover patterns, land-use technologies and land agroecological quality. Our research has been done in the fields of Precision farming experiment of Russian Timiryazev State Agrarian University (RTSAU) that soil cover and landscape patterns are typical for Moscow region of RF. The investigated fields include four 1-ha plots with winter wheat and potatoes with versions of traditional tillage and no-till. Each key plot comprises the representative sites for analysis the autotrophic and heterotrophic respiration, and control ones. Carbon dioxide fluxes have been weekly measured in June - September 2012, by the portable infrared system gas analyzer LI-COR LI-6400XT. The carried out research has shown the crop strong influence on the soil CO2 emission. In case of field with winter wheat in June - August it was in 1.5-2.5 times higher (2,93 μmol m-2 s-1) than in potatoes one. The maximum difference has been fixed at the first half of August after the wheat harvest. July is characterize by gradual decrease soil carbon dioxide emission from 1.56 μmol m-2 s-1 to 1.06 μmol m-2 s-1. Comparative analysis of the model sites with differentiation of the autotrophic and heterotrophic respiration showed the absolute dominance of microorganism contribution: 1.56 μmol m-2 s-1 (76.3% of the total respiration). It is especially important that no-till sites have CO2 "microbial" emission in 24.8% less the traditional tillage ones. The carried out in June-September comparative analysis of investigated sites with forest control ones has shown the following set with increasing soil CO2 emission: "winter wheat

    Background Satisfaction with services represents a key component of the user’s perspective, and user satisfaction surveys are the most commonly used approach to evaluate the aforementioned perspective. The aim of this discursive paper is to provide a critical overview of user satisfaction surveys in addiction treatment and harm reduction services, with a particular focus on opioid maintenance treatment as a representative case. Methods We carried out a selective critical review and analysis of the literature on user satisfaction surveys in addiction treatment and harm reduction services. Results Most studies that have reported results of satisfaction surveys have found that the great majority of users (virtually all, in many cases) are highly satisfied with the services received. However, when these results are compared to the findings of studies that use different methodologies to explore the patient’s perspective, the results are not as consistent as might be expected. It is not uncommon to find that “highly satisfied” patients report significant problems when mixed-methods studies are conducted. To understand this apparent contradiction, we explored two distinct (though not mutually exclusive) lines of reasoning, one of which concerns conceptual aspects and the other, methodological questions. Conclusion User satisfaction surveys, as currently designed and carried out in addiction treatment and harm reduction services, do not significantly help to improve service quality. Therefore, most of the enthusiasm and naiveté with which satisfaction surveys are currently performed and interpreted – and rarely acted on in the case of nonoptimal results – should be avoided. A truly participatory approach to program evaluation is urgently needed to reshape and transform patient satisfaction surveys. PMID:24482571

    Malaria is a condition that threatens millions of people in many countries in spite of precautions. Sporadic cases have not been observed in our country since 2010, but imported malaria cases are still to be seen because of migration. In this study, two malaria cases are presented that appeared in a non-endemic region within 1 week. Complaints appeared 20 days later after leaving Ivory Coast in the first case and one week after returning from Ghana in the second case. With this two import cases which have a travel story about two different countries and non taking regular chemoprophylaxis; it is aimed to call attention that malaria is a question of common concern and a protozoon which needs to be struggled worldwide.

    Introduction Each year there are approximately 390 million dengue infections worldwide. Weather variables have a significant impact on the transmission of Dengue Fever (DF), a mosquito borne viral disease. DF in mainland China is characterized as an imported disease. Hence it is necessary to explore the roles of imported cases, mosquito density and climate variability in dengue transmission in China. The study was to identify the relationship between dengue occurrence and possible risk factors and to develop a predicting model for dengue’s control and prevention purpose. Methodology and Principal Findings Three traditional suburbs and one district with an international airport in Guangzhou city were selected as the study areas. Autocorrelation and cross-correlation analysis were used to perform univariate analysis to identify possible risk factors, with relevant lagged effects, associated with local dengue cases. Principal component analysis (PCA) was applied to extract principal components and PCA score was used to represent the original variables to reduce multi-collinearity. Combining the univariate analysis and prior knowledge, time-series Poisson regression analysis was conducted to quantify the relationship between weather variables, Breteau Index, imported DF cases and the local dengue transmission in Guangzhou, China. The goodness-of-fit of the constructed model was determined by pseudo-R2, Akaike information criterion (AIC) and residual test. There were a total of 707 notified local DF cases from March 2006 to December 2012, with a seasonal distribution from August to November. There were a total of 65 notified imported DF cases from 20 countries, with forty-six cases (70.8%) imported from Southeast Asia. The model showed that local DF cases were positively associated with mosquito density, imported cases, temperature, precipitation, vapour pressure and minimum relative humidity, whilst being negatively associated with air pressure, with different time

    To provide best recommendations at the point of care, guidelines have been implemented in computer systems. As a prerequisite, guidelines are translated into a computer-interpretable guideline format. Since there are no specific tools to translate nursing guidelines, only a few nursing guidelines are translated and implemented in computer systems. Unified modeling language (UML) is a software writing language and is known to well and accurately represent end-users' perspective, due to the expressive characteristics of the UML. In order to facilitate the development of computer systems for nurses' use, the UML was used to translate a paper-based nursing guideline, and its ease of use and the usefulness were tested through a case study of a genetic counseling guideline. The UML was found to be a useful tool to nurse informaticians and a sufficient tool to model a guideline in a computer program.

    Central adiposity is a significant determinant of obesity-related hypertension risk, which may arise due to the pathogenic inflammatory nature of the abdominal fat depot. However, the influence of pro-inflammatory adipokines on blood pressure in the obese hypertensive phenotype has not been well established in Saudi subjects. As such, our study investigated whether inflammatory factors may represent useful biomarkers to delineate hypertension risk in a Saudi cohort with and without hypertension and/or diabetes mellitus type 2 (DMT2). Subjects were subdivided into four groups: healthy lean controls (age: 47.9±5.1 yr; BMI: 22.9±2.1 Kg/m2), non-hypertensive obese (age: 46.1±5.0 yr; BMI: 33.7±4.2 Kg/m2), hypertensive obese (age: 48.6±6.1 yr; BMI: 36.5±7.7 Kg/m2) and hypertensive obese with DMT2 (age: 50.8±6.0 yr; BMI: 35.3±6.7 Kg/m2). Anthropometric data were collected from all subjects and fasting blood samples were utilized for biochemical analysis. Serum angiotensin II (ANG II) levels were elevated in hypertensive obese (p<0.05) and hypertensive obese with DMT2 (p<0.001) compared with normotensive controls. Systolic blood pressure was positively associated with BMI (p<0.001), glucose (p<0.001), insulin (p<0.05), HOMA-IR (p<0.001), leptin (p<0.01), TNF-α (p<0.001) and ANG II (p<0.05). Associations between ANG II and TNF-α with systolic blood pressure remained significant after controlling for BMI. Additionally CRP (p<0.05), leptin (p<0.001) and leptin/adiponectin ratio (p<0.001) were also significantly associated with the hypertension phenotype. In conclusion our data suggests that circulating pro-inflammatory adipokines, particularly ANG II and, TNF-α, represent important factors associated with a hypertension phenotype and may directly contribute to predicting and exacerbating hypertension risk.

    Over a 30-year period (1968-1997) 213 malaria cases in Trinidad were investigated by the Trinidad and Tobago Ministry of Health. Using a global positional system and a geographic information system, we mapped the precise location of all reported malaria cases, and associated them with breeding habitats of anopheline vectors. The majority of the cases (138, 63%) were individual imported cases around the big port cities. Plasmodium falciparum was the most common parasite, and Africa the most common source of imported cases. Two clusters of cases occurred: an introduced P. vivax outbreak associated with Anopheles aquasalis in 1990-1991, and an autochtonous focus of P. malariae associated with An. bellator and An. homunculus in 1994-1995. Application of a space-time statistic showed a significant clustering of P. malariae cases, and, to a lesser extent of P. vivax cases, but not of P. falciparum cases. Based on potential for occurrence of local transmission, we are developing risk maps to determine surveillance priorities, outbreak potential, and necessary degree and spatial range of control activities following case detections.

    Aspergillus oryzae is widely used for the industrial production of enzymes. In A. oryzae metabolism, transporters appear to play crucial roles in controlling the flux of molecules for energy generation, nutrients delivery, and waste elimination in the cell. While the A. oryzae genome sequence is available, transporter annotation remains limited and thus the connectivity of metabolic networks is incomplete. In this study, we developed a metabolic annotation strategy to understand the relationship between the sequence, structure, and function for annotation of A. oryzae metabolic transporters. Sequence-based analysis with manual curation showed that 58 genes of 12,096 total genes in the A. oryzae genome encoded metabolic transporters. Under consensus integrative databases, 55 unambiguous metabolic transporter genes were distributed into channels and pores (7 genes), electrochemical potential-driven transporters (33 genes), and primary active transporters (15 genes). To reveal the transporter functional role, a combination of homology modeling and molecular dynamics simulation was implemented to assess the relationship between sequence to structure and structure to function. As in the energy metabolism of A. oryzae, the H+-ATPase encoded by the AO090005000842 gene was selected as a representative case study of multilevel linkage annotation. Our developed strategy can be used for enhancing metabolic network reconstruction. PMID:27274991

    Human infections caused by Dirofilaria repens, a cosmopolitan zoonotic parasitosis endemic in Southern and Eastern Europe and Asia still is an underdiagnosed infection due to parasite identification difficulties. Here, we report the first human case of subcutaneous dirofilariasis by D. repens diagnosed in Portugal. This was probably an imported case from India, as judged by epidemiological and clinical data. With this presentation we aim to alert clinicians for the emergence of vector-borne zoonoses associated with global warming and international travel. This case showed that differential diagnosis of D. repens in subcutaneous nodules is needed, in order to avoid further complications.

    The worldwide spread of severe acute respiratory syndrome (SARS) raised questions about the risk of importation of such infection, in particular by air travel. Entry screening was implemented in some countries although poor evidence on its effectiveness is reported. We developed a model to estimate the number of imported SARS cases between regions, using the 2003 SARS epidemic data to apply this model for two scenarios: from Beijing to Frankfurt and from Hong Kong to London. We back-calculated the data to estimate individuals' time of infection and built a model where every individual has a probability of being isolated, of traveling, and of being undetected at arrival. The findings, consistent with what was observed in 2003, suggest that entry screening does not affect the predicted number of imported cases. Inversely, importation depends on the transmission dynamic in the country of origin (including control measures in place) and on the intensity of air travel between regions. PMID:19079846

    On July 16 2015, the Puerto Rico Department of Health (PRDH) was notified of a case of malaria, diagnosed by a hospital parasitology laboratory in a student who had traveled to Punta Cana, Dominican Republic, during late June for a school-organized graduation trip. Malaria is a mosquito-borne parasitic infection, characterized by fever, shaking chills, headaches, muscle pains, nausea, general malaise, and vomiting (1). Malaria can be clinically difficult to distinguish from other acute febrile illnesses, and a definitive diagnosis requires demonstration of malaria parasites using microscopy or molecular diagnostic tests. The student's initial diagnosis on July 10 was suspected dengue virus infection. Puerto Rico eliminated local malaria transmission during the mid-1950s (2); however, reintroduction remains a risk because of the presence of a competent vector (Anopheles albimanus) and ease of travel to areas where the disease is endemic, including Hispaniola, the island shared by the Dominican Republic and Haiti, and the only island in the Caribbean with endemic malaria (3). During 2014, the Dominican Republic reported 496 confirmed malaria cases and four associated deaths; Haiti reported 17,662 confirmed cases and nine deaths (4). During 2000-2014, Puerto Rico reported a total of 35 imported malaria cases (range = 0-7 per year); three cases were imported from Hispaniola. During June-August 2015, eight confirmed malaria cases among travelers to the Dominican Republic were reported to CDC's National Malaria Surveillance System (CDC, unpublished data, 2015).

    Dengue fever has emerged as a major public health problem globally in the past three decades. A 13-year national surveillance data analysis was done to describe the epidemiology and its trend of dengue disease in Oman reported between 2001 and 2013. Laboratory-confirmed dengue virus infections reported were studied retrospectively during the study period. A total of 64 laboratory confirmed cases were reported. All the patients contracted the disease during their visit to South-East Asian countries, hence classified as imported cases. The majority of the cases were reported in the year 2012 (23.4%). The most important clinical characteristics were fever (90.6%), myalgia (35.9%) and rash/petechial rash (20.3%). Thrombocytopenia was seen in 31.2% of the study subjects. The mortality was nearly 4.6% and all other patients made a full recovery. The most effective measure for travellers is taking precautions to avoid mosquito bites.

    Chikungunya virus (CHIKV) is an arthropod-borne alphavirus that causes an acute febrile illness, chikungunya fever. CHIKV virus is geographically distributed in Africa, India, and South-East Asia. Chikungunya fever outbreaks have been reported from India since 2006. The incubation period is 3-7 days, and the disease is characterized by sudden onset of high fever and severe arthralgia. Other symptoms can be rash, headache, fatigue, nausea-vomiting, and myalgias. Here, we report the first Chikungunya case imported from India, New-Delhi to Ankara, Turkey. In December 2010, a 55-year-old female Turkish government employee living in urban area of New Delhi for the last 3 years had sudden onset fever up to 38.4°C for 2 days. Itching rash and arthralgia also developed. Symptomatic treatment was given to patient in New Delhi. She returned to Turkey and was admitted to Hacettepe University Medical Faculty, Department of Internal Medicine, Infectious Diseases Unit, since arthralgia has continued on the 26th day of her complaints. Hepatomegaly and tenosynovitis were detected in her physical examination. Serum sample sent to Refik Saydam National Public Health Agency, Virology Reference and Research Laboratory, yielded negative results for specific IgM and IgG antibodies against Hantavirus and Dengue virus types 1-4; however, the results were positive for CHIKV specific IgM and IgG antibodies by commercial immunofluorescence method (Euroimmun, Germany). CHIKV RNA which was searched by in-house real-time RT-PCR was negative. The second serum sample obtained three weeks later also found positive for CHIKV specific IgM and IgG antibodies. This was the first laboratory confirmed imported Chikungunya case in Turkey. There are predictions regarding the presence of Aedes species mosquitos that can transmit this virus in Turkey. This case report will be an alarming signal for the clinicians in our country to consider Chikungunya fever in the differential diagnosis of patients

    With up to 100 million cases annually, dengue fever is today's most important arboviral disease. Dengue fever is endemic in many parts of South-East Asia, the Indian subcontinent, Oceania and the Americas. The disease mainly affects the local population, but occasionally also visitors from non-endemic areas. In this article we present epidemiological and clinical data on all 26 cases with serological confirmed dengue fever diagnosed in Norway in 1991-1996. 21 patients (81%) were infected in Asia. Typical exanthema, leucopenia, and thrombocytopenia were seen in 71%, 79% and 84% of the cases, respectively. A 37-year-old Indian-born woman developed dengue haemorrhagic fever grade 1 after a visit to New Delhi, while the remaining 25 patients had classical dengue fever. Postinfectious complications were common, and four weeks after the acute illness, hair loss, mental depression and asthenia were reported by 45%, 50% and 100% of the cases, respectively.

    Inspection of a crime scene is a crucial step in forensic medicine, and even the methods taught by forensic anthropology are essential. Whereas a thorough inspection can provide crucial information, an approximate inspection can be useless or even harmful. This study reports 3 cases of burnt bodies found inside vehicles between 2006 and 2009 in the outskirts of Milan (Italy). In all 3 cases, the victim was killed by gunshot, and the body was burnt in the vehicle to destroy signs of skeletal injury and prevent identification. In every case, the assistance of forensic anthropologists was requested, but only after the inspection of the body at autopsy showed that the remains were incomplete, thus making it more difficult to determine the identity, cause, and manner of death. A second scene of crime inspection was therefore performed with strict anthropological and adapted archeological methods by forensic anthropologists to perform a more complete recovery, proving how much material had been left behind. These cases clearly show the importance of a proper recovery and of the application of forensic anthropology methods on badly charred bodies and the importance of recovering every fragment of bone: even the smallest fragment can provide essential information. Thus, a precise coordination, a correct and thorough recovery of bone fragments, and an anthropological approach are crucial for many issues: analysis of the scene of crime, reconstruction of the corpse, and reconstruction of the perimortem events.

    The cases of nine Polish patients with diagnosed cystic echinococcosis (CE) were examined. A total of nine isolates obtained postoperatively were investigated using PCR and sequencing. The mitochondrial region of nad1 gene was amplified. This PCR and sequencing analysis revealed the presence of Echinococcus canadensis G7 in seven patients and E. granulosus G1 in two patients. These data demonstrate that E. canadensis is the predominant causative agent of human cystic echinococcosis in Poland. E. granulosus G1 detection in Polish patients suggests that the parasite was imported; however it does not exclude the possibility that these cases could have been of Polish origin. PMID:26491683

    Human cutaneous myiasis is a common dermatosis in tropical zones. The purpose of this report is to describe the first imported case of furuncular myiasis caused by Dermatobia hominis (human botfly) in Tunisia. The patient was a man returning from Bolivia. Furuncular myiasis was suspected based on epidemiological data and clinical examination showing pruriginous elevated lesions. Diagnosis was confirmed by identification of Dermatobia hominis larvae. Treatment was based mainly on manual removal of larvae. Since furuncular myiasis is unknown in Tunisia, it is important to remember this parasitic disease in differential diagnosis in patients presenting boil-like inflammatory papules following travel to Latin America.

In this case report treatment of a 23-year-old student who had been elbowed by an opponent player during a basketball game, which caused oblique fractures on both maxillary incisor teeth is presented. The patient presented 17 days following trauma having completed full recovery of soft tissues. A fragment of upper incisor tooth had been embedded in lower lip at the time of trauma, which was covered by healing tissues. At the 1 month control the patient complained of a hard structure in his lower lip. The elusive broken fragment was revealed by a radiograph and then removed surgically. This case report is a good example of the importance of the training of general dentists about sports-related traumatic injuries as well as emphasising the importance of the use of mouthguards during contact sports.

    Leishmaniasis is a vector borne disease caused by protozoa of the genus Leishmania. Human leishmaniasis is not endemic in Australia though imported cases are regularly encountered. This study aimed to provide an update on the molecular epidemiology of imported leishmaniasis in Australia. Of a total of 206 biopsies and bone marrow specimens submitted to St Vincent’s Hospital Sydney for leishmaniasis diagnosis by PCR, 55 were found to be positive for Leishmania DNA. All PCR products were subjected to restriction fragment length polymorphism analysis for identification of the causative species. Five Leishmania species/species complexes were identified with Leishmania tropica being the most common (30/55). Travel or prior residence in a Leishmania endemic region was the most common route of acquisition with ~47% of patients having lived in or travelled to Afghanistan. Cutaneous leishmaniasis was the most common manifestation (94%) with only 3 cases of visceral leishmaniasis and no cases of mucocutaneous leishmaniasis encountered. This report indicates that imported leishmaniasis is becoming increasingly common in Australia due to an increase in global travel and immigration. As such, Australian clinicians must be made aware of this trend and consider leishmaniasis in patients with suspicious symptoms and a history of travel in endemic areas. This study also discusses the recent identification of a unique Leishmania species found in native kangaroos and a potential vector host which could create the opportunity for the establishment of a local transmission cycle within humans.

    Squamous cell carcinoma (SCC) is the second-most common malignant cutaneous cancer, with 60% occurring in the head and neck region. Metastases are uncommon and imply a more conservative prognosis. This report describes a case of parotid-invasive, facial squamous cell carcinoma, highlighting the importance of its prognostic and therapeutic management. The patient is an 81-year-old female, exhibiting extensive tumoral lesions in the pre-auricular region, affecting the parotid parenchyma and implying the metastatic involvement of the intra-parotid lymph node. Parotid involvement caused by SCC in specificity tumors is discussed herein. Parotid invasion is currently recognized as an isolated variable. It affects survival rates and determines certain changes in case management, such as the broadening of resection areas and adjuvant radiotherapy. PMID:27438204

    Reading Disorder (RD) belongs to Specific Learning Disorders within the chapter of Neurodevelopmental Disorders in the Diagnostic and Statistic Manual of Mental Disorders 5th edition. Previous research shows that the time of the diagnosis of RD - early (before starting school) or late - has a great impact on the prognosis. In the current paper we present the cases of two children diagnosed with RD. Our cases demonstrate that if RD is diagnosed in early childhood, the child's and his/her family's quality of life can be influenced in a positive direction, while late recognition of RD might influence the child's and the family's quality of life negatively. For these reasons it is important that experts recognize RD in time, start appropriate treatment and give proper support to children diagnosed with RD and their families.

    Usability has become established as an important aspect of product design. This paper describes an investigation that was carried out to identify the importance of usability in product choice related to other product attributes. Interviews were initially carried out to identify possible attributes that contribute to product choice. Experiments were then undertaken using the methods of active information search, structured preference elicitation, ranking and interviews in order to find out what attributes were important to people when choosing an example product - mobile phones. It was found that usability is indeed important in product choice but perhaps not as much as users themselves believe. Other attributes that were found to be more important were features, aesthetics and cost. The process of product choice was found to be complex and it may be the case that people have come to expect usability in their products. Further research is needed to understand more fully the changing role of usability in product choice and to further improve the quality of the user-product relationship.

  15. Low back pain in 17 year olds has substantial impact and represents an important public health disorder: a cross-sectional study

    2012-01-01

    Background Prevalence of low back pain (LBP) rises rapidly during adolescence, reaching adult levels by the age of 18. It has been suggested that adolescent LBP is benign with minimal impact, despite limited evidence. Methods The aim of this study was to investigate the impact of LBP and the influence of chronicity, gender and presence of other spinal pain comorbidities at age 17. Subjects (n = 1283) were categorised according to experiencing current and chronic LBP, gender and presence of other areas of spinal pain. LBP impact was ascertained via questions regarding seeking professional assistance, using medication, missing school/work, limited normal or recreational physical activity and health related quality of life (HRQOL). Results 12.3% of participants reported current but not chronic LBP, while 19.9% reported current chronic LBP. LBP was more commonly reported by females than males. Other spinal pain comorbidities were common in the LBP groups. Impact was greater in subjects with chronic LBP, in females and in those with other spinal pain comorbidities. Conclusion LBP, and particularly chronic LBP, has a significant negative impact at 17 years. It is commonly associated with care seeking, medication use, school absenteeism, and reduced HRQOL. These findings support that adolescent LBP is an important public health issue that requires attention. PMID:22304903

    2013-08-01

    Aviation emissions of NOx result in the formation of tropospheric ozone (warming) and destruction of a small amount of methane (cooling), positive and negative radiative forcing effects. In addition, the reduction of methane results in a small long-term reduction in tropospheric ozone (cooling) and, in addition, a long-term reduction in water vapour in the stratosphere (cooling) from reduced oxidation of methane, both negative radiative forcing impacts. Taking all these radiative effects together, aircraft NOx is still thought to result in a positive (warming) radiative effect under constant emissions assumptions. Previously, comparative modelling studies have focussed on the variability between models, using the same emissions database. In this study, we rather quantify the variability and uncertainty arising from different estimations of present-day aircraft NOx emissions. Six different aircraft NOx emissions inventories were used in the global chemical transport model, MOZART v3. The inventories were normalized to give the same global emission of NOx in order to remove one element of uncertainty. Emissions differed in the normalized cases by 23% at cruise altitudes (283-200 hPa, where the bulk of emission occurs, globally). However, the resultant short-term ozone chemical perturbation varied by 15% between the different inventories. Once all the effects that give rise to positive and negative radiative impacts were accounted for, the variability of net radiative forcing impacts was 94%. Using these radiative effects to formulate a net aviation NOx Global Warming Potential (GWP) for a 100-year time horizon resulted in GWPs ranging from 60 to 4, over an order of magnitude. It is concluded that the detailed placement of emissions at chemically sensitive cruise altitudes strongly affects the assessment of the total radiative impact, introducing a hitherto previously unidentified large fraction of the uncertainty of impacts between different modelling assessments.

    Introduction Dengue is endemic in more than 100 countries, mainly in tropical and subtropical regions, and the incidence has increased 30-fold in the past 50 years. The situation of dengue in China has become more and more severe, with an unprecedented dengue outbreak hitting south China in 2014. Building a dengue early warning system is therefore urgent and necessary for timely and effective response. Methodology and Principal Findings In the study we developed a time series Poisson multivariate regression model using imported dengue cases, local minimum temperature and accumulative precipitation to predict the dengue occurrence in four districts of Guangzhou, China. The time series data were decomposed into seasonal, trend and remainder components using a seasonal-trend decomposition procedure based on loess (STL). The time lag of climatic factors included in the model was chosen based on Spearman correlation analysis. Autocorrelation, seasonality and long-term trend were controlled in the model. A best model was selected and validated using Generalized Cross Validation (GCV) score and residual test. The data from March 2006 to December 2012 were used to develop the model while the data from January 2013 to September 2014 were employed to validate the model. Time series Poisson model showed that imported cases in the previous month, minimum temperature in the previous month and accumulative precipitation with three month lags could project the dengue outbreaks occurred in 2013 and 2014 after controlling the autocorrelation, seasonality and long-term trend. Conclusions Together with the sole transmission vector Aedes albopictus, imported cases, monthly minimum temperature and monthly accumulative precipitation may be used to develop a low-cost effective early warning system.

    The outcome of screening the household contacts of 49 newly diagnosed tuberculous children as currently practised in the Paediatric Unit of the Port Moresby General Hospital is described. The screening program generated 182 chest X-rays and 67 Mantoux tests. 32 (39%) of 83 child contacts and 11 (11%) of 99 adults were commenced on antituberculous therapy, and 2 children aged 6 months were started on INAH chemoprophylaxis. Adult contacts were identified in 11 (22%) of the 49 families screened. Such a program is an extremely important part of the case management of children with newly diagnosed tuberculosis and their families.

    A case of tuberculosis presenting as a neck lump is highlighted. Tuberculosis is on the increase. There are national and international strategies to improve the management of tuberculosis in the United Kingdom, and raising clinical awareness of tuberculosis is an important part of that strategy. Neck lumps can present in the dental setting and the differential diagnosis should include tuberculosis, with referral to an appropriate multidisciplinary team. Special tests to aid diagnosis are helpful but not completely discriminating. Tuberculosis is a notifiable disease and it must be treated by a designated specialist medical team. CPD/Clinical Relevance: Tuberculosis is a differential diagnosis for a persistent neck lump and clinicians should understand the problems of diagnosis and the importance of appropriate referral for treatment in the national and international strategy to reduce this disease.

    The Ebola virus disease, as a first epidemic in West Africa, stands as the most deadly one throughout history. Guinea, the source of the epidemic, Sierra Leone and Liberia remain the most strongly affected. That epidemic thoroughly destabilized the health system of those countries. Following Nigeria, Senegal received its first imported case from the neighboring Republic of Guinea. In that sub regional psychotic context, such a situation has been handled and managed starting from the potential of a health system that is already suitably structured. The organization of the response, the management of the communication system and the rigorous monitoring of contacts have been decisive in the control of the epidemic. Our countries have to be prepared in order to face health threats, and that is the reason why the need to empower our health systems is important. PMID:26740836

    1995-01-01

    The clinical, haematological and biochemical profiles of all domestic and imported malaria cases admitted to the Hospital Kuala Lumpur were analysed. The most common malaria types were Plasmodium falciparum (39.5%) and Plasmodium vivax (42%). The most common patient type was men aged 29-40 years (reflecting the high mobility of this group, many of whom were illegal immigrants). Misdiagnosis on admission was frequently due to the variable clinical presentation of the disease and the difficulties of obtaining an accurate history. Associated haematological abnormalities were common. Chloroquine resistance was diagnosed in four P. falciparum patients and in one P. falciparum/vivax patient. Overall, imported malaria did not seem more severe than domestic. The three patients with cerebral malaria survived. One patient died of acute liver failure. The large influx of illegal immigrants to Malaysia has resulted in a surge in malaria infection; illegal immigrants remain a source of chloroquine resistance.

    Otodectes cynotis, ear mite or ear canker mite, is the most common cause of otitis external in cats (approximately 50%) and to a lesser extent in dogs, foxes and ferrets. The mite is living on the epidermal surface of auditory canal without burrowing into the tissue and feeding on tissue fluids and debris. In most of the cases they induce hypersensitivity reactions in the host. Four puppies; Siberian husky, Cocker spaniel, Terrier and mixed Pekignese with different genders and ages were referred to the Small Animal Hospital, Veterinary Faculty of Tehran University, Tehran, Iran for routine clinical examination just after they were imported from Thailand in a timeframe between June to August 2008.Clinical examinations showed an excessive dark brown discharge in both ears. No signs of other clinical situations were observed. White moving mites were seen during otoscopy examination, the specimen of ear discharge was sent to parasitology laboratory for precise identification of genus and species. Mites were identified as Otodectes cynotis and the presence of concurrent yeast and bacterial infection was showed by laboratory examinations. Topical Amitraz solution in combination with otic antibacterial and antifungal agents were administered as the treatment. Since, all the reported cases were imported from Thailand, careful clinical examination and quarantine strategies are highly recommended at the borders.

    This paper describes the production and characteristics of the nanoparticle test materials prepared for common use in the collaborative research project NanoChOp (Chemical and optical characterisation of nanomaterials in biological systems), in casu suspensions of silica nanoparticles and CdSe/CdS/ZnS quantum dots. This paper is the first to illustrate how to assess whether nanoparticle test materials meet the requirements of a 'reference material' (ISO Guide 30:2015) or rather those of the recently defined category of 'representative test material' (ISO TS 16195:2013). The NanoChOp test materials were investigated with small-angle X-ray scattering (SAXS), dynamic light scattering (DLS) and centrifugal liquid sedimentation (CLS) to establish whether they complied with the required monomodal particle size distribution. The presence of impurities, aggregates, agglomerates and viable microorganisms in the suspensions was investigated with DLS, CLS, optical and electron microscopy and via plating on nutrient agar. Suitability of surface functionalization was investigated with attenuated total reflection Fourier transform infrared spectrometry (ATR-FTIR) and via the capacity of the nanoparticles to be fluorescently labeled or to bind antibodies. Between-unit homogeneity and stability were investigated in terms of particle size and zeta potential. This paper shows that only based on the outcome of a detailed characterization process one can raise the status of a test material to representative test material or reference material, and how this status depends on its intended use.

    2006-01-01

    In today's competitive, fast-changing world of healthcare, organizations cannot tolerate ineffective leadership over the long term if they are to remain successful. It is very common for leadership teams to come together and immediately begin to do business...at least to attempt to do what each team member believes the group's business should be. Unfortunately, each person probably has a different idea of what the team's business should be, and how they should go about conducting it. This is a certain recipe for ineffectiveness. The following case study examines how the executive team in a health sciences college approached the development of an effective leadership team, and discusses the importance of process to achieving the desired outcomes. The process so described can be used with any leadership team, but it should always be customized to suit the unique needs and desires of each team.

  6. Preventable long-term complications of suprapubic cystostomy after spinal cord injury: Root cause analysis in a representative case report

    2011-01-01

    Background Although complications related to suprapubic cystostomies are well documented, there is scarcity of literature on safety issues involved in long-term care of suprapubic cystostomy in spinal cord injury patients. Case Presentation A 23-year-old female patient with tetraplegia underwent suprapubic cystostomy. During the next decade, this patient developed several catheter-related complications, as listed below: (1) Suprapubic catheter came out requiring reoperation. (2) The suprapubic catheter migrated to urethra through a patulous bladder neck, which led to leakage of urine per urethra. (3) Following change of catheter, the balloon of suprapubic catheter was found to be lying under the skin on two separate occasions. (4) Subsequently, this patient developed persistent, seropurulent discharge from suprapubic cystostomy site as well as from under-surface of pubis. (5) Repeated misplacement of catheter outside the bladder led to chronic leakage of urine along suprapubic tract, which in turn predisposed to inflammation and infection of suprapubic tract, abdominal wall fat, osteomyelitis of pubis, and abscess at the insertion of adductor longus muscle Conclusion Suprapubic catheter should be anchored securely to prevent migration of the tip of catheter into urethra and accidental dislodgment of catheter. While changing the suprapubic catheter, correct placement of Foley catheter inside the urinary bladder must be ensured. In case of difficulty, it is advisable to perform exchange of catheter over a guide wire. Ultrasound examination of urinary bladder is useful to check the position of the balloon of Foley catheter.

    Dengue virus and its four serotypes (DENV 1-4) infect approximately 390 million people worldwide each year, with most cases in tropical and subtropical regions. Because of repeated introduction of DENV from epidemic regions and suitable weather conditions, many regions have shifted from hypo-endemicity to hyper-endemicity over recent decades. Since the first dengue outbreak in 1978, it is crucial to understand the current situation in China over nearly 40 years. The purpose of the study was to examine whether dengue in China was endemic or not, which is essential for relevant dengue control and prevention strategy implementation in China. The study, combining epidemiological characteristics of dengue from the disease notification system, phylogenetic and phylogeographic analyses, showed that all four serotypes had been detected in Guangzhou, China, which was dominated by DENV 1-2. The Maximum Likelihood tree analytic results showed that the virus detected in Guangzhou localized in different clades, except of virus of 2002 and 2003 clustered together. There existed the mutual introductions between Guangzhou and Southeast Asia. Most of the viruses were imported from Southeast Asia and the sources of outbreaks in Guangzhou mainly originated from Thailand, Indonesia, and the Philippines. The study indicates that dengue in China still remains as an imported disease, with the possibility of localization.

    Although typhoid fever is no longer endemic in most of the developed world, it remains a major infectious disease in less developed regions and imported cases continue to occur in returning travellers, immigrants or migrant workers. We analysed all 692 isolates of Salmonella enterica subspecies enterica serovar Typhi from cases in England, Scotland and Wales that were sent to the Laboratory of Enteric Pathogens at the Health Protection Agency, Centre for Infections, London, UK between 2000 and 2003. The country of acquisition was known for 416 isolates (60%), and the majority of these (70%) came from India or Pakistan. Overall, 24 countries were listed, mainly in Asia and Africa. A total of 48 phage types were detected, 41% of which were Vi-phage type E1. Antimicrobial susceptibility testing revealed that 22% of isolates were multidrug resistant (MDR) (defined as resistance to chloramphenicol, ampicillin and co-trimoxazole) and 39% were quinolone resistant. A significant number of isolates (n=49) were sensitive to nalidixic acid by disk test but exhibited low-level ciprofloxacin resistance, suggesting a novel mechanism of resistance and reinforcing the need for minimum inhibitory concentration determination. Overall, 13% of isolates were both MDR and likely to show a poor response to a fluoroquinolone. A third-generation cephalosporin (e.g. ceftriaxone) should be considered as empirical therapy in regions of the Indian subcontinent where resistance is now at high levels as well as in patients returning from these areas. This study helps to describe the epidemiology of antimicrobial drug resistance in typhoid fever.

    Mining activities have been carried out for centuries in Sierra Minera (SE Spain) giving rise to a large number of sites distributed throughout the zone in which residues are accumulated. This communication reports studies as regards metal mobilization and analysis of the health risk that could be posed by inhalation, dermic contact or occasional ingestion of this type of sediments. Lead was used as the metal for the studies due to its particular abundance in the zone. A large number of samples were taken and general analytical determinations (pH, particle size, organic matter, equivalent calcium carbonate content and mineralogical composition) were carried out in order its characterization. An in vitro method for obtaining formation on Pb bioaccessibility in these mine waste materials was also carried out. Our results prove that mineral associations, different alteration states and sorption/desorption processes play an important role in the bioavailability of lead. In addition, it is noteworthy that the metal fraction dissolved by the proposed in vitro methodology is lower than 100%, both in the stomach and intestinal phases. Finally an assessment of the risk posed by lead is achieved. To this respect it should be noted that the IRIS database provide cancer slope factor and reference dose, as a way to assess the risk caused by arsenic, cadmium and copper but no for lead, probably due to the wide variety of real situations, and the discrepancy of the sources. The way here suggested is a novelty in this sense, and the results could be extrapolated to other similar zones and be incorporated to the general protocol of risk assessment applied to contaminated sites.

    ) consistent with government objectives to prevent introduction of pests and diseases, promote development of future aquaculture industries or maintain biodiversity. It is concluded that the risk analysis process described by the Office International des Epizooties under the SPS agreement cannot be used in a meaningful way for current patterns of ornamental fish trade. Transboundary disease incursions will continue and exotic pathogens will become established in new regions as a result of the ornamental fish trade, and this will be an international phenomenon. Ornamental fish represent a special case in live animal trade where OIE guidelines for risk analysis need to be revised. Alternatively, for countries such as Australia with implied very high ALOP, the number of species traded and the number of sources permitted need to be dramatically reduced to facilitate hazard identification, risk assessment and import quarantine controls.

    Neurocysticercosis (NCC), a parasitic disease caused by the larvae of the cestode Taenia solium, is the most frequent parasitic disease of the central nervous system (CNS) in the world and the leading cause of secondary epilepsy in Central and South America, East and South Asia, and sub-Saharan Africa. It is endemic in many low- and middle-income countries of the world. Due to increased travels and immigration, NCC may be diagnosed also in non-endemic areas. In fact, tapeworm carriers from endemic zones can transmit infection to other citizens or arrive already suffering NCC. This phenomenon, occurred first in USA during the last 30 years, has been also observed in Europe, as well as in Australia, Canada, Israel, Japan and Muslim countries of the Arab World. Actually, concerning Europe, although, in some areas only few cases have been described, nevertheless the prevalence of NCC may be considered increasing, especially in Spain and Portugal. We reviewed the literature on the burden of NCC in Europe, by a search of PubMed regarding papers from 1970 to present. We only considered on PubMed published and available papers in English, French, Italian, and Spanish, the languages understood by the authors. One hundred seventy six cases of NCC have been reported in seventeen European countries (Austria, Belgium, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Netherlands, Sweden, United Kingdom, and Croatia, Norway, Switzerland). A particular epidemic situation is present in Spain and Portugal. In fact, we collected data that show, in Spain, an increasing incidence both in immigrated patients and in those which were born in certain Spanish geographical areas and, in Portugal, prevalence similar to that observed in endemic areas. Globally, it is clear that as a result of increased migrations and travels from endemic regions, NCC is becoming an emerging public health problem in high-income countries, particularly affecting communities where

    Finland is fully self-sufficient in clean groundwater and even has a capacity of exportation. There are approx. 6000 groundwater areas with a total yield of 5.4 million m3/day. Currently only 10% of this groundwater resource is in use. For the efficient and safe exploitation of these areas in the future, detailed modeling of soil structure is an important method in groundwater surveys. 3D -models improve the general knowledge of linkage between land use planning and groundwater protection. Results can be used as a base information in water supply service development and when performing the measures needed in case of environmental accidents. Also, when creating the groundwater flow models the collected information is utilized and is usually the main data source. Geological Survey of Finland has carried out soil structure studies in co-operation with authorities, municipalities and the local water suppliers. The main objectives of these projects are to determine the geological structure of groundwater area for estimating the validity of the present exclusion area, the quantity of ground water volume and recharge capability and possible risks to the groundwater. Research areas are usually under an active water supply service. Kauvonkangas groundwater area is located in the municipality of Tervola, in Southern part of Finnish Lapland. Extent of the area is 7.9 km2 and it is an important water source for the local and nearby population centers. There are two active water supply companies in the area. Field studies in the project will include general geological and hydrological mapping, soil drilling with observation pipe installation, test pumping and water sampling. Geophysical measures will play a key-role, including ground penetrating radar (GPR) and gravimetric measurements. Studies will be carried out in spring and summer 2016. The main results will be the models of the bedrock and groundwater level and main characteristics of the soil layers in the area. Results

    In recent years, there has been a substantial increase of imported Plasmodium vivax incidence in Henan Province. As China is in a pre-elimination phase, the surveillance of imported malaria is essential, but there is no good way to distinguish imported cases from indigenous cases. This paper reports a case of a 39-year-old man who acquired P. vivax while staying in Indonesia for one month in 2013, and relapsed in Henan, China in 2014. This was diagnosed as vivax malaria based on rapid diagnostic test, Giemsa-stained peripheral blood smear and Plasmodium species-specific nested PCR. The genetic sequence for the circumsporozoite protein genes was analysed and the genetic variations were compared with a previously constructed database of Chinese isolates. The results from the circumsporozoite protein (CSP) gene sequence analysis centered on the repeat patterns showed that the imported cases had completely different sequences from any subtypes from Chinese isolates, but well matched with the countries travelled by the patient. The imported vivax cases were able to clearly distinguish from the indigenous vivax cases by detecting the CSP gene and were able to confim its origin by genotyping.

    We seek to investigate the compositional surface variation of near Earth asteroids (NEAs). To do this, we employ detailed shape models and near-IR observations, taken over a range of viewing geometries, in order to create thermophysical models. The thermal spectra are therefore linked to regions on the asteroid, and we can seek out a set of thermal parameters that are capable of reproducing the thermal spectra over the entirety of the asteroid's surface. This method also enables us to characterize portions of the asteroid that may have different thermal properties than other regions, in which case there is no single set of thermal parameters that satisfy all of the thermal observations, indicating a heterogeneous surface.We present our findings on 1627 Ivar, an Amor class NEA with a taxonomic type of Sqw [1], and a rotation period of 4.7951689 hr ± 0.0000026 [2]. During Ivar's apparition in 2013, we obtained CCD lightcurves, radar data, and near-IR spectra. Using the software SHAPE, we have used lightcurve and radar data to generate an improved shape model of Ivar [2][3].For the thermophysical modeling, we have used SHERMAN [3,4] to determine which reflective, thermal, and surface properties for Ivar best reproduce our spectra, taken using the SpeX instrument at the NASA IRTF [5]. Input parameters for SHERMAN include the asteroid's IR emissivity, optical scattering law and thermal inertia in order to complete thermal computations based on the shape model. We also compare these results to those created by using the Kaasalainen lightcurve model [6]. Since models created from lightcurve inversion techniques far outnumber those created using radar data, it is important to understand how these two models differ when studying thermal models.References: [1] DeMeo et al. 2009, Icarus 202, 160-180 [2] Crowell et al. 2016, Icarus, in press [3] Crowell et al. 2014, AAS/DPS 46 [4] Howell et al. 2015, AAS/DPS 47 [5] Rayner et al. 2003, PASP 115, 362 [6] Kaasalainen et al. 2004

    Background Is a heterogeneous disorder characterized by clonal proliferation of mast cells (MCs) leading accumulation in different organs. Pathologic activation of KIT due to a mutation in codon 816 replacing aspartic acid for valine: KIT-D816V (>93%) has been identified. Cutaneous Mastocytosis (CM), Classified in Urticaria Pigmentosa (UP), solitary mastocytoma, diffuse, and telangiectasia macularis eruptiva perstans (TMEP). The most common is the Urticaria Pigmentosa as fixed, reddish brown macular or papular, urticate in physical irritation (Darier's sign). WHO Diagnostic Criteria for cutaneous Mastocytosis: Presence of at least 1 of skin lesions with Focal dense MC infiltrates (>15 MCs per cluster) or diffuse (>20 cells per high-power field). Methods We report 2 cases of patients with this disease who were not diagnosed at first. A 51 years old female, who noticed 20 years ago, the appareance of itchy "spots” in thorax, abdomen and extremities, progressively increasing in number and size, receiving unspecified treatments without improvement. On examination, we found brown macules with sharp borders, 0.3 to 0.5 cm erythema and Darier´s sign, disseminated lesions on thorax, shoulders and extremities. A 45 year old female, who noticed 2 years ago, the appareance of freckles in neck, arms, thorax and legs progressively increasing in number, who in stress are itchy. Receiving multiple treatments without improvement. On examination disseminated brown macules with sharp borders <0.5 cm with Darier´s sign. Results In both patients, the biopsies taken had findings compatible with mastocytosis (inflammatory infiltrate with perivascular lymphocytes, histiocytes and mast cells). Mast cells were not quantified. We realized a genetic study in search of c-kit mutation. Once the diagnosis was considered and treated accordingly, they had a good control of symptoms. Conclusions Mastocytosis is diagnosed by clinical features and histological infiltrate of mast cells. The skin

    Schizophrenia is a debilitating syndrome with high heritability. Genomic studies reveal more than a hundred genetic variants, largely nonspecific and of small effect size, and not accounting for its high heritability. De novo mutations are one mechanism whereby disease related alleles may be introduced into the population, although these have not been leveraged to explore the disease in general samples. This paper describes a framework to find high impact genes for schizophrenia. This study consists of two different datasets. First, whole exome sequencing was conducted to identify disruptive de novo mutations in 14 complete parent-offspring trios with sporadic schizophrenia from Jerusalem, which identified 5 sporadic cases with de novo gene mutations in 5 different genes (PTPRG, TGM5, SLC39A13, BTK, CDKN3). Next, targeted exome capture of these genes was conducted in 48 well-characterized, unrelated, ethnically diverse schizophrenia cases, recruited and characterized by the same research team in New York (NY sample), which demonstrated extremely rare and potentially damaging variants in three of the five genes (MAF<0.01) in 12/48 cases (25%); including PTPRG (5 cases), SCL39A13 (4 cases) and TGM5 (4 cases), a higher number than usually identified by whole exome sequencing. Cases differed in cognition and illness features based on which mutation-enriched gene they carried. Functional de novo mutations in protein-interaction domains in sporadic schizophrenia can illuminate risk genes that increase the propensity to develop schizophrenia across ethnicities.

    Schizophrenia is a debilitating syndrome with high heritability. Genomic studies reveal more than a hundred genetic variants, largely nonspecific and of small effect size, and not accounting for its high heritability. De novo mutations are one mechanism whereby disease related alleles may be introduced into the population, although these have not been leveraged to explore the disease in general samples.

    Tungiasis is an animal and human parasitic disease caused by fleas of the genus Tunga (Siphonaptera, Tungidae), endemic in equatorial and subtropical regions and rarely described in European countries, where clinicians and general pathologists could be not aware of this parasitic disease. To our knowledge, only 75 cases of human tungiasis (not all described in detail) were previously reported in Italy. We described a new case in a 34-year-old Italian flight attendant who developed a granuloma-like, ulcerated nodule in the subungual region of his left 5th toe, partially detaching the nail, about 20-30 days after his return from Brazil. We performed a detailed review of the literature of the Italian cases, suggesting the use of histochemical stains (especially Trichrome stain) in order to underline parasitic details. Tourism in endemic regions and globalization may result in new cases in developed countries and previously unaffected regions, therefore pathologists should consider this parasitic disease.

    The objective of this study was to improve risk assessments of travel on dengue (DEN) virus (DENV) distribution. We investigated the exposure risk of US citizens traveling to DEN-endemic Pan American countries. The number of DEN cases reported in 51 Pan American countries from 2001 to 2012 was compared to the population of the same countries. The number of US travelers visiting the Pan American countries was categorized by region, and travel-related DEN infections were analyzed. US residents visiting the Dominican Republic exhibited the highest traveler-related DEN incidence. Brazil showed the most DEN cases in its residents (>1 million reported cases in 2010). The number of DEN cases continues to rise as does international travel and the geographic range of potential DENV vectors. DENV risk assessments may be improved by analyzing the possible routes of entry. Underreporting remains an issue for calculating DENV transmission risk by country and region. PMID:26766913

    possible to produce short and long term forecasts. While the statistic of extremes is useful for many stakeholders, short term forecasts could be of importance for the whole society. Whatever the case, the prediction errors have to be emphasizes even more than the forecasts. The most common forecast in terms of general public understanding is the weather prediction. Nowadays, general public knows it well enough to properly deal with the uncertainties, because after so many year of not perfect forecasts, society knows the limits. Other coastal hazards deserve to be presented more carefully, and some successful example of the use of the precautionary principle could be observed, for instance, on the Pacific Tsunami alert system. Nowadays, the preparedness of the coastal population is good enough (even in such big and diverse area) not to be bored to run up the hill, most of the times unnecessarily, because they know the uncertainty and accept it. The key issue we, scientists, have to work better at any level, is the need of properly estimate and communicate the uncertainties of our results, cause they are not obvious nor irrelevant.

    Dengue virus (DENV) transmission in Australia is driven by weather factors and imported dengue fever (DF) cases. However, uncertainty remains regarding the threshold effects of high-order interactions among weather factors and imported DF cases and the impact of these factors on autochthonous DF. A time-series regression tree model was used to assess the threshold effects of natural temporal variations of weekly weather factors and weekly imported DF cases in relation to incidence of weekly autochthonous DF from 1 January 2000 to 31 December 2009 in Townsville and Cairns, Australia. In Cairns, mean weekly autochthonous DF incidence increased 16.3-fold when the 3-week lagged moving average maximum temperature was <32 °C, the 4-week lagged moving average minimum temperature was ≥24 °C and the sum of imported DF cases in the previous 2 weeks was >0. When the 3-week lagged moving average maximum temperature was ≥32 °C and the other two conditions mentioned above remained the same, mean weekly autochthonous DF incidence only increased 4.6-fold. In Townsville, the mean weekly incidence of autochthonous DF increased 10-fold when 3-week lagged moving average rainfall was ≥27 mm, but it only increased 1.8-fold when rainfall was <27 mm during January to June. Thus, we found different responses of autochthonous DF incidence to weather factors and imported DF cases in Townsville and Cairns. Imported DF cases may also trigger and enhance local outbreaks under favorable climate conditions. PMID:26038449

    In intra-EU trade, the health status of animals is warranted by issuing a health certificate after clinical inspection in the exporting country. This certificate cannot provide guarantee of absence of infection, especially not for diseases with a long incubation period and no overt clinical signs such as bovine tuberculosis (bTB). The Netherlands are officially free from bTB since 1999. However, frequent reintroductions occurred in the past 15 years through importation of infected cattle. Additional testing (AT) of imported cattle could enhance the probability of detecting an imported bTB infection in an early stage. The goal of this study was to evaluate the effectiveness of risk-based AT for bTB in cattle imported into The Netherlands. A generic stochastic import risk model was developed that simulates introduction of infection into an importing country through importation of live animals. Main output parameters are the number of infected animals that is imported (Ninf), the number of infected animals that is detected by testing (Ndet), and the economic losses incurred by importing infected animals (loss). The model was parameterized for bTB. Model calculations were optimized to either maximize Ndet or to minimize loss. Model results indicate that the risk of bTB introduction into The Netherlands is very high. For the current situation in which Dutch health checks on imported cattle are limited to a clinical inspection of a random sample of 5-10% of imported animals, the calculated annual Ninf=99 (median value). Random AT of 8% of all imported cattle results in Ndet=7 (median value), while the median Ndet=75 if the sampling strategy for AT is optimized to maximize Ndet. However, in the latter scenario, loss is more than twice as large as in the current situation, because only calves are tested for which cost of detection is higher than the expected gain of preventing a possible outbreak. When optimizing the sampling strategy for AT to minimize loss, only breeding

    In 2009, the National Research Council published a report stating that the addition of more science and technology into the field of forensic science in the United States would be of great benefit to the judicial system. As a starting point to address this NRC report, one needs to make an assessment of the system. One factor that is continuously requested is an estimate of an error rate. In any given scientific area of forensics that is difficult to quantitate except by external review and audits. After eight years of requested defense review of cases with biological and DNA evidence, most cases appear to be scientifically sound in test methods and procedures. However, there were some cases where errors in the forensic science process did occur. This article takes information compiled from those eight years of defense review and summarizes the cases where errors have been discovered and discusses the scientific implications of these errors. The scope of this article is limited to crime scene collection and forensic science laboratory testing of biological materials for body fluid identification and DNA individualization to a source. The greatest value of defense review comes from (a) providing effective balance and independent oversight to the judicial process and (b) collecting data into a format that can be useful as a guide in training programs.

    Chikungunya virus, a mosquito-borne alphavirus, is endemic in Africa and Southeast Asia but is rarely reported in Taiwan. We report the case of a Taiwanese woman who developed Chikungunya fever, which was first diagnosed by a clinician rather than by fever screening at an airport. The woman presented with fever, maculopapular rash, and arthralgia, the triad for the disease, on the day she returned home after a trip to Malaysia. These symptoms are very similar to those of dengue fever, which is endemic in Southern Taiwan. Chikungunya infection was confirmed by reverse transcriptase-polymerase chain reaction and seroconversion on paired serum specimens. For approximately 40 years until 2006, no cases of Chikungunya fever had been found in Taiwan. Clinicians in Taiwan should consider Chikungunya fever as a possible diagnosis for a febrile patient with arthralgia, rash, and a history of travel to an endemic area, such as Africa or Southeast Asia.

Following multiple mosquito bites in Martinique Island in January 2014, the patient presented with high fever, headaches, arthralgia on both hands and feet, and a rash on the trunk upon his return to Canada. Initial serological testing for dengue virus infection was negative. Support therapy with nonsteroidal anti-inflammatory drugs was administered. The symptoms gradually improved 4 weeks after onset with residual arthralgia and morning joint stiffness. This clinical feature prompted the clinician to request CHIKV virus serology which was found to be positive for the presence of IgM and neutralizing antibodies. In 2014, over four hundred confirmed CHIKV infection cases were diagnosed in Canadian travellers returning from the Caribbean and Central America. Clinical suspicion of CHIKV or dengue virus infections should be considered in febrile patients with arthralgia returning from the recently CHIKV endemic countries of the Americas. PMID:27366163

    The dengue virus is responsible for a wide range of symptoms that can be classified into two distinct syndromes: classical dengue fever and severe dengue fever. Among the complicating forms, hemophagocytic syndrome (HPS) has been previously reported in case series of patients with secondary dengue fever outside of endemic settings. Of note, the occurrence of HPS has not yet been included among the criteria for defining severe dengue fever. We herein present three patients with HPS related to confirmed primary dengue virus infection. Clinicians should therefore consider hemophagocytosis as a complication during severe dengue infection in naïve patients.

  7. Clozapine-induced interstitial nephritis - a rare but important complication: a case report

    PubMed Central

    2009-01-01

    Introduction Given the limited range of effective drug treatments for patients with schizophrenia, increasing numbers of patients, often termed 'treatment-resistant' are prescribed clozapine. While the induction of neutropenia or agranulocytosis by clozapine is well appreciated, other rare potentially fatal adverse reactions may also occur including acute interstitial nephritis as reported in this case. Case presentation A 57-year-old Caucasian woman with treatment-resistant chronic schizophrenia developed acute renal failure following initiation of treatment with clozapine. The adverse reaction occurred after only four doses of the drug had been administered (titrated from 12.5 to 25 mg per day). After clozapine had been withdrawn, the patient's renal function returned to normal with no other changes to medication. The patient had been exposed to clozapine about 4 years previously when she had developed a similar reaction. Conclusion Renal reactions to clozapine are extremely rare but, if not recognized promptly, may prove fatal. Psychiatrists need to be aware of this possible complication when clozapine is initiated.

    A mass die-off of imported red tailed knobby newts (Tylototriton kweichowensis) occurred in 2004 in Belgium and the Netherlands. In addition to massive infection with Rhabdias tokyoensis, Ranavirus was isolated from three dead newts examined virologically and the gene coding for the major capsid protein of the virus was sequenced. The isolate showed 99.8% similarity to the published sequence of frog virus 3. Upon experimental infection of axolotls (Ambystoma mexicanum) with this isolate, no marked pathology was noticed and the virus could not be re-isolated at 9weeks post-inoculation. Apart from the possibility of exposure of a non-sensitive host, the mortality episode in the newts may be related to stress resulting from the importation of the newts in breeding condition. This possibility is supported by the presence of degenerating egg-follicles in the females.

    2012-11-01

    This paper studies the impact of the re-importation of imitated pharmaceuticals as a by-product of an open policy toward parallel import (PI) on process innovation. Foreign investment by a firm to exploit a new unregulated market with weak intellectual property rights can give rise to imitation. These products can potentially re-enter the original country when PI is allowed influencing research and development (R&D) incentives. In an emerging economy with technologically heterogeneous firms, trade costs shift PI-related market share losses from the more to the less R&D efficient firm, inducing the former to strategically increase R&D. PI accompanied by tariffs also induces higher R&D effort by the technologically inferior firm when it results in an expansion of its sales abroad. A tariff on PI is most likely to increase welfare when the technological gap between the two firms at home is sufficiently large.

    The portion of the eastern Sicily coastline (southern Italy), ranging from the southern part of the Catania Gulf (to the north) down to the southern-eastern end of the island, represents a very important geographical domain from the industrial, commercial, military, historical and cultural points of view. Here the two major cities of Augusta and Siracusa are found. In particular, the Augusta bay hosts one of the largest petrochemical poles in the Mediterranean, and Siracusa is listed among the UNESCO World Heritage Sites since 2005. This area was hit by at least seven tsunamis in the approximate time interval from 1600 BC to present, the most famous being the 365, 1169, 1693 and 1908 tsunamis. The choice of this area as one of the sites for the testing of innovative methods for tsunami hazard, vulnerability and risk assessment and reduction is then fully justified. This is being developed in the frame of the EU Project called ASTARTE - Assessment, STrategy And Risk Reduction for Tsunamis in Europe (Grant 603839, 7th FP, ENV.2013.6.4-3). We assess the tsunami hazard for the Augusta-Siracusa area through the worst-case credible scenario technique, which can be schematically divided into the following steps: 1) Selection of five main source areas, both in the near- and in the far-field (Hyblaean-Malta escarpment, Messina Straits, Ionian subduction zone, Calabria offshore, western Hellenic Trench); 2) Choice of potential and credible tsunamigenic faults in each area: 38 faults were selected, with properly assigned magnitude, geometry and focal mechanism; 3) Computation of the maximum tsunami wave elevations along the eastern Sicily coast on a coarse grid (by means of the in-house code UBO-TSUFD) and extraction of the 9 scenarios that produce the largest effects in the target areas of Augusta and Siracusa; 4) For each of the 9 scenarios we run numerical UBO-TSUFD simulations over a set of five nested grids, with grid cells size decreasing from 3 km in the open Ionian

    Background: The most frequent form of inflammatory bowel disease (IBD) in dogs is represented histologically, by lymphoplasmacytic enteritis (LPE), a histological category, often associated with other morphologic alterations including lymphangiectasia (LE). However, literature data on this latter topic are quite scarce and have mostly been obtained in single reports or in small series. Aim: We evaluated some morphologic parameters of intestinal villi and lacteals in a large cohort of dogs, and correlated them with serum albumin and cholesterol values. Patients and methods: We investigated 136 dogs (94 with LPE, and 42 with gastrointestinal problems different from IBD) and analyzed their clinical, laboratory (albumin and cholesterol values), endoscopic, and histologic variables. Results: The LPE group showed significantly impaired clinical, laboratory, endoscopic, and histologic variables compared to controls. Affected dogs showed significant correlations between canine inflammatory bowel disease activity index (CIBDAI) scores and endoscopic and histologic variables. Moreover, the grade of hematologic changes were strongly related to the intestinal histologic variables, in particular those concerning villous and lacteals morphology. Conclusion: Dogs with LPE had intestinal histologic abnormalities (height, width, height/width ratio, calculated for both villi and lacteals), whose degree correlated with the severity of hypoalbuminemia and hypocholesterolemia. Evaluation of endoscopic and histologic variables in association to the clinical findings may reveal useful insights for the pathogenesis of LPE and, hopefully, might lead to more targeted therapeutic approaches.

    Tungiasis is a cutaneous ectoparasitosis caused by the sand flea Tunga penetrans whose higher prevalence occurs in South America, the Caribbean and Sub-Saharan Africa. It is clinically characterized by a papular lesion, either single or multiple, with a whitish halo and a brown-black central core, most of them localized on the feet. The lesions can be painful and itchy with the most common complication being bacterial superinfection of the skin. We report three cases of Chilean patients who presented skin lesions suggestive of tungiasis on their return from areas of high prevalence of the disease. The diagnosis is made by the clinical features of lesions in a patient from an endemic zone. Standard treatment consists of surgical extraction of the flea followed by application of a topical antibiotic and a tetanus prophylaxis. Prevention of the infestation is essential and includes the use of closed footwear and repellents. PMID:24522316

    In Mexico, out-of-hospital cardiac arrest is a health problem that represents 33,000 to 150,000 or more deaths per year. The few existent reports show mortality as high as 100% in contrast to some international reports that show higher survival rates. In Queretaro, during the last 5 years there were no successful resuscitation cases. However, in 2012 some patients were reported to have return of spontaneous circulation. We report in this article 3 cases with return of spontaneous circulation and pulse at arrival to the hospital. Two of the patients were discharged alive, one of them with poor cerebral performance category. Community cardiopulmonary resuscitation, early defibrillation and better emergency medical system response times, are related with survival. This poorly explored health problem in Queretaro could be increased with quality and good public education, bystander assisted cardiopulmonary resuscitation, police involvement in cardiopulmonary resuscitation and defibrillation, public access defibrillation programs and measurement of indicators and feedback for better results.

    Nodular leukoplakia is a non-homogeneous type of oral leukoplakia presenting a white surface with verrucous, nodular, ulcerated or erythematous features with a greater risk of malignant transformation when compared to the homogeneous type. Common sites of involvement include lip commissures, buccal mucosa and soft palate. It is often associated with epithelial dysplasia or carcinoma and requires detailed microscopic assessment and regular follow-up. The importance of a proper selection of the area to be biopsied and the close teamwork between a dentist and oral pathologist is the basis of providing an accurate final diagnosis.

    Next generation sequencing (NGS) platforms are replacing traditional molecular biology protocols like cloning and Sanger sequencing. However, accuracy of NGS platforms has rarely been measured when quantifying relative frequencies of genotypes or taxa within populations. Here we developed a new bioinformatic pipeline (QRS) that pools similar sequence variants and estimates their frequencies in NGS data sets from populations or communities. We tested whether the estimated frequency of representative sequences, generated by 454 amplicon sequencing, differs significantly from that obtained by Sanger sequencing of cloned PCR products. This was performed by analysing sequence variation of the highly variable first internal transcribed spacer (ITS1) of the ichthyosporean Caullerya mesnili, a microparasite of cladocerans of the genus Daphnia. This analysis also serves as a case example of the usage of this pipeline to study within-population variation. Additionally, a public Illumina data set was used to validate the pipeline on community-level data. Overall, there was a good correspondence in absolute frequencies of C. mesnili ITS1 sequences obtained from Sanger and 454 platforms. Furthermore, analyses of molecular variance (amova) revealed that population structure of C. mesnili differs across lakes and years independently of the sequencing platform. Our results support not only the usefulness of amplicon sequencing data for studies of within-population structure but also the successful application of the QRS pipeline on Illumina-generated data. The QRS pipeline is freely available together with its documentation under GNU Public Licence version 3 at http://code.google.com/p/quantification-representative-sequences.

    The internal concentration of chemicals in exposed organisms changes over time due to absorption, distribution, metabolism, and excretion processes since chemicals are taken up from the environment. Internal concentration and time are very important modifiers of toxicity when biomarkers are used to evaluate the potential hazards and risks of environmental pollutants. In this study, the responses of molecular biomarkers, and the fate of chemicals in the body, were comprehensively investigated to determine cause-and-effect relationships over time. Chlorpyrifos (CP) was selected as a model chemical, and Caenorhabditis elegans was exposed to CP for 4 h using the passive dosing method. Worms were then monitored in fresh medium during a 48-h recovery regime. The mRNA expression of genes related to CYP metabolism (cyp35a2 and cyp35a3) increased during the constant exposure phase. The body residue of CP decreased once it reached a peak level during the early stage of exposure, indicating that the initial uptake of CP rapidly induced biotransformation with the synthesis of new CYP metabolic proteins. The residual chlorpyrifos-oxon concentration, an acetylcholinesterase (AChE) inhibitor, continuously increased even after the recovery regime started. These delayed toxicokinetics seem to be important for the extension of AChE inhibition for up to 9 h after the start of the recovery regime. Comprehensive investigation into the molecular initiation events and changes in the internal concentrations of chemical species provide insight into response causality within the framework of an adverse outcome pathway.

    Background Adolescence is transitional stage of physical and mental human development occuring between childhood and adult life. Social interactions and environmental factors together are important predictors of adolescent cannabis use. This study aimed to examine the relationship between the social determinants and adolescents behavior with cannabis consumption. Methods: A cross sectional study as part of the European School Survey Project on Alcohol and other Drugs was conducted among 6.150 adolescents aged 16 years in three regions of Serbia, and three types of schools (gymnasium, vocational – professional, and vocational – handicraft) during May – June 2008. A multivariate logistic regression analysis was carried out to obtain adjusted odds ratios with 95% confidence intervals in which the dependent variable was cannabis consumption non-user and user. Results: Among 6.7% of adolescents who had tried cannabis at least one in their lives, boys were more involved in cannabis use than girls, especially boys from gymnasium school. Well off family, lower education of mother, worse relations with parents were significantly associated with cannabis use (P < 0.05). Behaviors like skipping from schools, frequent evening outs, and playing on slot machines were also related to cannabis use (P < 0.05). Conclusions: The study confirmed the importance of family relationship development. Drug use preventive programmes should include building interpersonal trust in a family lifecycle and school culture. PMID:23641402

    In this study, we surveyed diversity in a range of local crops in the Lume and Gimbichu districts of Ethiopia, together with the knowledge of local people regarding crop uses, socio-economic importance, conservation, management and existing threats. Data were collected using semistructured interviews and participant observation. The study identified 28 farmers' varieties of 12 crop species. Among these, wheat (Triticum turgidum) and tef (Eragrostis tef) have high intra-specific diversity, with 9 and 6 varieties respectively. Self-seed supply or seed saving was the main (80 %) source of seeds for replanting. Agronomic performance (yield and pest resistance), market demand, nutritional and use diversity attributes of the crop varieties were highlighted as important criteria for making decisions regarding planting and maintenance. Over 74 % of the informants grow a combination of "improved" and farmers' varieties. Of the farmers' varieties, the most obvious decline and/or loss was reported for wheat varieties. Introduction of improved wheat varieties, pest infestation, shortage of land, low yield performance and climate variability were identified as the principal factors contributing to this loss or decline. Appropriate interventions for future conservation and sustainable use of farmers' varieties were suggested. PMID:22729809

    The correct planning of agriculture areas is fundamental for a sustainable future in Ukraine. After the recent political problems in Ukraine, new challenges emerged regarding sustainability questions. At the same time the soil mapping and modelling are intensively developing all over the world (Pereira et al., 2015; Brevik et al., in press). Magnetic susceptibility (MS) methods are low cost and accurate for the developing maps of agricultural areas, fundamental for Ukrain's economy.This allow to colleact a great amount of soil data, usefull for a better understading of the spatial distribution of soil properties. Recently, this method have been applied in other works in Ukraine and elsewhere (Jordanova et al., 2011; Menshov et al., 2015). The objective of this work is to study the spatial distribution of MS and humus content on the topsoils (0-5 cm) in two different areas. The first is located in Poltava region and the second in Kharkiv region. The results showed that MS depends of soil type, topography and anthropogenic influence. For the interpretation of MS spatial distribution in top soil we consider the frequency and time after the last tillage, tilth depth, fertilizing, and the puddling regarding the vehicle model. On average the soil MS of the top soil of these two cases is about 30-70×10-8 m3/kg. In Poltava region not disturbed soil has on average MS values of 40-50×10-8 m3/kg, for Kharkiv region 50-60×10-8 m3/kg. The tilled soil of Poltava region has on average an MS of 60×10-8 m3/kg, and 70×10-8 m3/kg in Kharkiv region. MS is higher in non-tilled soils than in the tilled ones. The correlation between MS and soil humus content is very high ( up to 0.90) in both cases. Breivik, E., Baumgarten, A., Calzolari, C., Miller, B., Pereira, P., Kabala, C., Jordán, A.

    The aim of this work is to review the literature on risk factors of oral cavity cancer with a special attention to the definition of the cases, in order to highlight special features of these cancers and of their subsites. PubMed database was systematically searched to access relevant articles published between 1980 and 2010. Reference lists of selected papers were examined to identify further articles. One hundred and two studies met the inclusion criteria. Their results were difficult to compare because of the lack of uniformity in defining oral cavity. In addition, few studies examined risk factors other than alcohol and tobacco, and studies differentiating between subsites were rare. Despite these limitations, some characteristics of oral cavity cancers may be emphasized: smoked tobacco seems to be a stronger risk factor for oral cavity cancer than alcohol, and the floor of the mouth seems to be more sensitive to the harmful effects of alcohol and smoked tobacco. Studies limited strictly to oral cavity cancers and distinguishing between subsites are needed to better understand the aetiology of these cancers, and better define risk groups to target prevention efforts and screening.

    In this paper we focus on the evaluation, assessment, diagnostic conclusions, and individual psychotherapy of a four year old twin who presented with the symptom of encopresis. Of great relevance to this boy is the literature concerning his vulnerability as a twin to develop symptomatology as he starts dealing with separation and individuation issues. Especially relevant are the multiple impacts of attitudes, perceptions and family rearing issues on the psychological development of this twin, and also on the development of this specific symptom choice--encopresis. Incorporating literature with case material, the meaning of the symptom of encopresis to this twin is discussed. The hypothesis defended is that the symptom enabled the twin to attract attention from his somewhat favoured brother, and to promote the process of separation and individuation from his parents and from his twin. It promoted his sense of himself as a separate and unique person in his own right. The child developed a sense of himself despite parental interference. With individual psychotherapy and family therapy, the need for the symptom was neglected. PMID:3676992

We determined the kinetics of antibody (IgG and IgM) and neutralizing antibodies against MERS-coronavirus (MERS-CoV) in this case before discharge. Moreover, no seroconversion was found among 53 close contacts by anti-MERS IgG antibody enzyme-linked immunosorbent assay (ELISA) of paired serum samples. These findings suggest that neither community nor nosocomial transmission of MERS-CoV occurred in China. PMID:27109133

    As new pollution regulations are created and existing regulations are made more complex, it is becoming more important for plant personnel to have a knowlege of the environment. The Environmental Representative Program is designed to train plant personnel and is aimed at preventing fines, citations, and negative publicity. The goal of the program is on-going daily compliance assurance, and is divided into two segments: 1) program initiation (general considerations, representative selection, and authorization by management); and 2) program implementation (requirements training, responsibilities development, incorporation into annual goals, and program maintenance). A discussion of how each part of the program is accomplished is presented.

    PURPOSE: Urban youths' agency to represent their realities through media has been largely unexplored in the youth development literature. In this qualitative case study of an after-school youth media program in the Bay Area, expressions of youth agency and the role of audiences are explored during the process of producing videos for public consumption. METHODOLOGY: As participant observer of 14 ethnically diverse youth participants aged between 15 and 18 years over 18 months, I documented (a) the kind of agencies participants engaged in and (b) the impact of live and imagined future audiences on youths' creative processes. Analyses of field notes, semi-structured interviews, and media projects were conducted using thematic analysis to inductively generate emerging categories. FINDINGS: Themes included an agentive sense of self-efficacy, commitment, and responsibility, as well as perceived contributions to local audiences and an emerging collective identity. The youth demonstrated their increased sense of a social or civic duty to realistically represent youth of color to familiar and unfamiliar audiences. IMPLICATIONS: This case study demonstrated how one youth media organization fostered agency through youth authorship, production, distribution, and local community dialogue. By documenting the impact of audiences from conception to public reception, this study provides valuable insight into the agentive process of publicly "performing" a commitment to complete a social change video project. CONTRIBUTION: This chapter underscores the value of performance within youth development programs and the critical component of audiences as one form of authentic assessment in order to foster individual and collective agency.

    Objective There is increasing interest in using electronic health records (EHRs) to identify subjects for genomic association studies, due in part to the availability of large amounts of clinical data and the expected cost efficiencies of subject identification. We describe the construction and validation of an EHR-based algorithm to identify subjects with age-related cataracts. Materials and methods We used a multi-modal strategy consisting of structured database querying, natural language processing on free-text documents, and optical character recognition on scanned clinical images to identify cataract subjects and related cataract attributes. Extensive validation on 3657 subjects compared the multi-modal results to manual chart review. The algorithm was also implemented at participating electronic MEdical Records and GEnomics (eMERGE) institutions. Results An EHR-based cataract phenotyping algorithm was successfully developed and validated, resulting in positive predictive values (PPVs) >95%. The multi-modal approach increased the identification of cataract subject attributes by a factor of three compared to single-mode approaches while maintaining high PPV. Components of the cataract algorithm were successfully deployed at three other institutions with similar accuracy. Discussion A multi-modal strategy incorporating optical character recognition and natural language processing may increase the number of cases identified while maintaining similar PPVs. Such algorithms, however, require that the needed information be embedded within clinical documents. Conclusion We have demonstrated that algorithms to identify and characterize cataracts can be developed utilizing data collected via the EHR. These algorithms provide a high level of accuracy even when implemented across multiple EHRs and institutional boundaries. PMID:22319176

    Is importing second-hand products (SHPs) good for Cambodia? To answer this question, one must seriously consider environmental and social effects. The main objective of this study is to identify and assess the economic, social, and environmental impacts of imported SHPs to determine whether or not Cambodia benefits. Imported second-hand computers (SHPCs) and second-hand tires (SHTs) were selected as cases for the study. The study used a scaling checklist to identify significant impacts of these two imported items. Significant impacts were ranked and rated into a single value (score) for integration. Integrated impact assessment showed that imported SHPCs create a very small positive impact (+ 0.1 of + 5) and imported SHTs generate a large negative impact (- 2.83 of - 5). These scores are mainly the result of environmental impact, predominantly waste issues. Thus, current imports of SHPCs and SHTs do not really benefit Cambodia, but instead cause serious environmental problems from their waste issues. The import serves as a channel to transfer waste into developing countries.

    This paper reviews and compares the condition of the environmental impact assessment (EIA) system in three countries in the East Africa region: Kenya, Rwanda and Tanzania. The criteria used for the evaluation and the comparison of each system are based on the elements of the legal, administrative and procedural frameworks, as well as the context in which they operate. These criteria are adapted from the evaluation and quality control criteria derived from a number of literature sources. The study reveals that the EIA systems of Kenya and Tanzania are at a similar stage in their development. The two countries, the first to introduce the EIA concept into their jurisdiction in this part of Africa, therefore have more experience than Rwanda in the practice of environmental impact assessment, where the legislation and process requires more time to mature both from the governmental and societal perspective. The analysis of the administrative and procedural frameworks highlights the weakness in the autonomy of the competent authority, in all three countries. Finally a major finding of this study is that the contextual set up i.e. the socio-economic and political situation plays an important role in the performance of an EIA system. The context in developing countries is very different from developed countries where the EIA concept originates. Interpreting EIA conditions in countries like Kenya, Rwanda and Tanzania requires that the analysis for determining the effectiveness of their systems should be undertaken within a relevant framework, taking into account the specific requirements of those countries.

    Numerous experimental studies have shown several benefits of treating burns by the immediate application of cool water. In this study of 695 children with burns, treated in the National Burn Institute (NBI), Hanoi, Vietnam, patients were assessed on admission according to first aid measures at the time of injury, i.e. the removal of the cause and immediate cooling with cold water. A total of 33% of the children who had had immediate cooling of the burn with water had deep burns, compared with 49% of the children who had not had immediate cooling. The prevalence ratio of deep burns was thus 0.68 (95% confidence interval (CI) 0.55-0.85); that is, there was an estimated reduction of 32% in the need for skin grafting, a reduction which was statistically significant. After adjusting for the effect of cooling the burn, removal of the causal agent reduced the odds of requiring skin grafting, but the reduction was not statistically significant. It is concluded that early cooling will prevent a significant percentage of superficial burns from progressing to deep burns. This will not only reduce the probability that skin grafting and expensive treatment will be required, but will reduce the risk of other consequences of deep burns, which may be fatal. Public health programs to promote immediate cooling of burns with cool water are at least as important as subsequent medical and surgical treatment in determining the outcome of burns in children.

    Spawning site selection and reproductive timing affect stock productivity and structure in marine fishes but are poorly understood. Traditionally, stock assessments measure reproductive potential as spawning stock biomass or egg production and do not include other aspects of reproductive behavior. Red drum make an excellent case study to assess these other aspects, as (1) they are highly fecund, pelagic spawners, like most exploited marine fishes; (2) their life cycle is delineated between nursery (estuarine) and adult (coastal and offshore) habitat; and (3) they are managed at these two spatial scales. This study was conducted from August 2012 to December 2013 and integrates data from multiple methods and spatial scales. Aerial surveys were used for large-scale monitoring of aggregations off two known estuarine nursery areas, Tampa Bay and Charlotte Harbor, Florida, USA. Capture-based sampling in Tampa Bay coastal (n = 2581) and estuarine waters (n = 158) was used to assess reproductive state and to confirm coastal spawning. To assess spatial dynamics, we acoustically tagged two population components in the Tampa Bay system, subadults from the estuary (n = 20) and adults from the coastal spawning site (n = 60). Behavioral plasticity was seen in subadult recruitment to coastal habitat, with some subadults maturing and recruiting before or during the spawning season and others (14 of 20 acoustically tagged fish) recruiting at the end of the 2012 spawning season. Both adults and recruited subadults (n = 29) were consequently detected in the Charlotte Harbor array, 132 km to the south. Spawning-site fidelity to the Tampa Bay spawning site occurred at both the population and individual scales. Aggregations consistently occurred in Tampa Bay coastal waters during the spawning season, and approximately two-thirds of tagged adults returned in the 2013 spawning season. A similar proportion of subadults returned to the Tampa Bay spawning site, exhibiting natal homing

    Spawning site selection and reproductive timing affect stock productivity and structure in marine fishes but are poorly understood. Traditionally, stock assessments measure reproductive potential as spawning stock biomass or egg production and do not include other aspects of reproductive behavior. Red drum make an excellent case study to assess these other aspects, as (1) they are highly fecund, pelagic spawners, like most exploited marine fishes; (2) their life cycle is delineated between nursery (estuarine) and adult (coastal and offshore) habitat; and (3) they are managed at these two spatial scales. This study was conducted from August 2012 to December 2013 and integrates data from multiple methods and spatial scales. Aerial surveys were used for large-scale monitoring of aggregations off two known estuarine nursery areas, Tampa Bay and Charlotte Harbor, Florida, USA.

    On December 19, 2005, 14 in vitro-fertilized water buffalo (Bubalus bubalis) embryos, which had been cryopreserved by vitrification, were thawed and transferred into B. bubalis recipients in California. The embryos had been produced in Italy, following transvaginal oocyte pickup (TVOPU), with subsequent in vitro maturation, insemination, and culture. This case study relates our experience in meeting the regulatory criteria, established by the Animal Import/Export Office of the USDA-Animal and Plant Health Inspection Service (USDA-APHIS), in order to successfully import these embryos into the USA.

    We present results from life history interviews with 60 young adults from southern Uganda. Using a novel qualitative case-control design, we compared newly HIV-positive cases with HIV-negative controls matched on age, gender, marital status, and place of residence. Relationship context was the most salient theme differentiating cases from controls. Compared with HIV-negative respondents, recent seroconverters described relationships marked by poorer communication, greater suspicion and mistrust, and larger and more transitory sexual networks. Results highlight the importance of dyadic approaches to HIV and possibly of couple-based interventions. Using HIV-matched pairs allowed additional understanding of the factors influencing transmission. This hybrid methodological approach holds promise for future studies of sexual health.

    Ten years have elapsed since the severe acute respiratory syndrome outbreak, which resulted in more than 8000 cases worldwide with more than 700 deaths. Recently, a new coronavirus, the Middle East Respiratory Syndrome Coronavirus emerged, causing serious respiratory cases and death. By the end of August 2013, 108 cases including 50 deaths were reported. The authors discuss a coronavirus-associated severe acute respiratory syndrome, which was detected in Hungary in 2005 and highlight its significance in 2013. In 2005 the patient was hospitalized and all relevant clinical and microbiological tests were performed. Based on the IgG antibody positivity of the serum samples, the patient was diagnosed as having severe acute respiratory syndrome coronavirus infection in the past. The time and source of the infection remained unknown. The condition of the patient improved and he was discharged from the hospital. The case raises the possibility of infections in Hungary imported from remote areas of the world and the importance of thorough examination of patients with severe respiratory syndrome with unknown etiology.

    Purpose Urban youths' agency to represent their realities through media has been largely unexplored in the youth development literature. In this qualitative case study of an after-school youth media program in the Bay Area, expressions of youth agency and the role of audiences are explored during the process of producing videos for public consumption. Methodology As participant observer of 14 ethnically diverse youth participants aged between 15 and 18 years over 18 months, I documented (a) the kind of agencies participants engaged in and (b) the impact of live and imagined future audiences on youths' creative processes. Analyses of field notes, semi-structured interviews, and media projects were conducted using thematic analysis to inductively generate emerging categories. Findings Themes included an agentive sense of self-efficacy, commitment, and responsibility, as well as perceived contributions to local audiences and an emerging collective identity. The youth demonstrated their increased sense of a social or civic duty to realistically represent youth of color to familiar and unfamiliar audiences. Implications This case study demonstrated how one youth media organization fostered agency through youth authorship, production, distribution, and local community dialogue. By documenting the impact of audiences from conception to public reception, this study provides valuable insight into the agentive process of publicly “performing” a commitment to complete a social change video project. Contribution This chapter underscores the value of performance within youth development programs and the critical component of audiences as one form of authentic assessment in order to foster individual and collective agency.

    In some cases, determination of blood alcohol level is very important. The alcohol level at the time of an event, can affect the court decision and may lead to aggravate the penalty or on the contrary an acquittal. In this article, a criminal action, in one of Turkish High Criminal Court is examined. The case was about the death of a drunk person who had fallen down from the window of his girl friend's house which is on the third floor of an apartment. This person's parent applied to public prosecutor saying that their child did not fall down but was murdered by his girl friend. During this trial, in the victim's autopsy, no alcohol detected in blood in contrast with his girl friend's testimony. Because of this contradiction, a reasonable doubt has emerged that she was the murderer in this suspicious death. However, in the further stages of trial, the reasons of no alcohol detection in the autopsy is investigated. In the basis of this case, the importance and techniques of alcohol detection in blood is discussed with literature.

    Reports of myiasis in humans in New Zealand are somewhat rare, and little attention has been paid to this issue in the local medical literature. A number of Diptera (fly) families present in New Zealand have been associated with cases of human myiasis: Calliphoridae (7 species), Fanniidae (2 species), Muscidae (3 species), Oestridae (4 species), Phoridae (3 species), Psychodidae (1 species), Sarcophagidae (2 species), Stratiomyidae (1 species) and Syrphidae (1 species). Despite these numbers, there have only been 6 published records and we obtained further 16 unpublished reports of myiasis acquired in New Zealand. Records of imported myiasis in humans are also rare, with only 2 published and 6 unpublished cases obtained. As many medical practitioners are unaware of myiasis or encounter it rarely, we provide a brief discussion of the clinical features and treatment. PMID:20930889

    Following a first clinical case of infection by Diphyllobothrium dendriticum in Switzerland in 2006, we report a second case in the country. The species was identified by molecular methods. In the Swiss, French and Italian subalpine regions, human diphyllobothriasis has seen a comeback since the late 1980's, and Diphyllobothrium latum is usually considered the causative agent of the disease. In addition, several locally acquired and imported clinical infections due to allochthonous Diphyllobothrium species have been documented in the last years. Due to the colonisation potential of these parasites and their probably underestimated presence in the human population, there is a need for discriminating them at the medical laboratory level. Because the morphological characters are very similar among the different taxa, a correct identification requires the use of molecular methods. Molecular identification would improve diagnosis and help monitor the distribution of Diphyllobothrium species in Europe. PMID:23351654

    Trade has a disproportionate environmental impact, while the international fragmentation of production promotes different patterns of intermediate inputs and final goods. Therefore, we split up the balance of domestic embodied emissions in trade (BDEET) to assess it. We find that Spain has a significant emissions deficit with China between 2005 and 2011. The Global Financial Crisis of 2008 reduced Spanish imports of pollution-intensive inputs from China and slightly improved the BDEET. China primarily exports indirect virtual carbon, representing 86% of the total, especially from Production of electricity, gas, and water sector. These linkages effects in China indicate that post-Kyoto agreements must focus not only on traded goods but also on the environmental efficiency of all domestic production chains. The methodology proposed allows us to identify the agents responsible for this trade in both Spain and China, namely the sectors importing intermediate inputs (Construction and Transport equipment) and industries and consumers importing final goods (Textiles, Other manufactures, Computers, and Machinery). The relevant sectors uncertainties found when we compare the results for BDEET and emissions embodied in bilateral trade (BEET) lead us to recommend the former methodology to evaluate the implications of environmental and energy policy for different industries and agents.

    2011-07-01

    We report the single-case study of a brain-damaged individual, JJG, presenting with a conceptual deficit and whose knowledge of living things, man-made objects, and actions was assessed. The aim was to seek for empirical evidence pertaining to the issue of how conceptual knowledge of objects, both living things and man-made objects, is related to conceptual knowledge of actions at the functional level. We first found that JJG's conceptual knowledge of both man-made objects and actions was similarly impaired while his conceptual knowledge of living things was spared as well as his knowledge of unique entities. We then examined whether this pattern of association of a conceptual deficit for both man-made objects and actions could be accounted for, first, by the "sensory/functional" and, second, the "manipulability" account for category-specific conceptual impairments advocated within the Feature-Based-Organization theory of conceptual knowledge organization, by assessing, first, patient's knowledge of sensory compared to functional features, second, his knowledge of manipulation compared to functional features and, third, his knowledge of manipulable compared to non-manipulable objects and actions. The later assessment also allowed us to evaluate an account for the deficits in terms of failures of simulating the hand movements implied by manipulable objects and manual actions. The findings showed that, contrary to the predictions made by the "sensory/functional", the "manipulability", and the "failure-of-simulating" accounts for category-specific conceptual impairments, the patient's association of deficits for both man-made objects and actions was not associated with a disproportionate impairment of functional compared to sensory knowledge or of manipulation compared to functional knowledge; manipulable items were not more impaired than non-manipulable items either. In the general discussion, we propose to account for the patient's association of deficits by the

    Background Dengue is a major mosquito-borne viral disease and an important public health problem. Identifying which factors are important determinants in the risk of dengue infection is critical in supporting and guiding preventive measures. In South-East Asia, half of all reported fatal infections are recorded in Indonesia, yet little is known about the epidemiology of dengue in this country. Methodology/Principal findings Hospital-reported dengue cases in Banyumas regency, Central Java were examined to build Bayesian spatial and spatio-temporal models assessing the influence of climatic, demographic and socio-economic factors on the risk of dengue infection. A socio-economic factor linking employment type and economic status was the most influential on the risk of dengue infection in the Regency. Other factors such as access to healthcare facilities and night-time temperature were also found to be associated with higher risk of reported dengue infection but had limited explanatory power. Conclusions/Significance Our data suggest that dengue infections are triggered by indoor transmission events linked to socio-economic factors (employment type, economic status). Preventive measures in this area should therefore target also specific environments such as schools and work areas to attempt and reduce dengue burden in this community. Although our analysis did not account for factors such as variations in immunity which need further investigation, this study can advise preventive measures in areas with similar patterns of reported dengue cases and environment.

    In August 2004, a case of rabies was diagnosed in a puppy that had been illegally imported from Morocco to Bordeaux (France). Because a great number of people and animals were thought to have come into contact with the puppy, extensive tracing measures were implemented, and an international alert was launched to trace and treat the contacts at risk. One hundred and eighty seven people received post-exposure treatment, eight of whom also received serovaccination, and 57 animals known to have been exposed to the puppy were tested. Six months after the death of the rabid animal, none of the people treated showed any signs of rabies, nor was any secondary animal case reported. The management of this crisis highlights the importance of the role of a rapid alert system at European level. Strict application of sanitary control regulations is essential for animals introduced into EU countries, and all necessary information must be made available to EU residents travelling to rabies enzootic areas.

    While imported falciparum malaria has been increasingly reported in recent years in Korea, clinicians have difficulties in making a clinical diagnosis as well as in having accessibility to effective anti-malarial agents. Here we describe an unusual case of imported falciparum malaria with severe hemolytic anemia lasting over 2 weeks, clinically mimicking a coinfection with babesiosis. A 48-year old Korean man was diagnosed with severe falciparum malaria in France after traveling to the Republic of Benin, West Africa. He received a 1-day course of intravenous artesunate and a 7-day course of Malarone (atovaquone/proguanil) with supportive hemodialysis. Coming back to Korea 5 days after discharge, he was readmitted due to recurrent fever, and further treated with Malarone for 3 days. Both the peripheral blood smears and PCR test were positive for Plasmodium falciparum. However, he had prolonged severe hemolytic anemia (Hb 5.6 g/dl). Therefore, 10 days after the hospitalization, Babesia was considered to be potentially coinfected. A 7-day course of Malarone and azithromycin was empirically started. He became afebrile within 3 days of this babesiosis treatment, and hemolytic anemia profiles began to improve at the completion of the treatment. He has remained stable since his discharge. Unexpectedly, the PCR assays failed to detect DNA of Babesia spp. from blood. In addition, during the retrospective review of the case, the artesunate-induced delayed hemolytic anemia was considered as an alternative cause of the unexplained hemolytic anemia. PMID:25548419

    Middle East respiratory syndrome (MERS) has spread worldwide since 2012. As the clinical symptoms of MERS tend to be non-specific, the incubation period has been shown to complement differential diagnosis, especially to rule out influenza. However, because an infection event is seldom directly observable, the present study aims to construct a diagnostic model that predicts the probability of MERS diagnosis given the time from immigration to illness onset among imported cases which are suspected of MERS. Addressing censoring by considering the transmission dynamics in an exporting country, we demonstrate that the illness onset within 2 days from immigration is suggestive of influenza. Two exceptions to suspect MERS even for those with illness onset within 2 days since immigration are (i) when we observe substantial community transmissions of MERS and (ii) when the cases are at high risk of MERS (e.g. cases with close contact in hospital or household). It is vital to collect the information of the incubation period upon emergence of a novel infectious disease, and moreover, in our model, the fundamental transmission dynamics including the initial growth rate has to be explored to differentiate the disease diagnoses with non-specific symptoms.

    Purpose The purpose of the current study was to assess the penetrance of NRXN1 deletions. Methods We compared the prevalence and genomic extent of NRXN1 deletions identified among 19,263 clinically referred cases to that of 15,264 controls. The burden of additional clinically relevant CNVs was used as a proxy to estimate the relative penetrance of NRXN1 deletions. Results We identified 41 (0.21%) previously unreported exonic NRXN1 deletions ascertained for developmental delay/intellectual disability, significantly greater than in controls [OR=8.14 (95% CI 2.91–22.72), p< 0.0001)]. Ten (22.7%) of these had a second clinically relevant CNV. Subjects with a deletion near the 3′ end of NRXN1 were significantly more likely to have a second rare CNV than subjects with a 5′ NRXN1 deletion [OR=7.47 (95% CI 2.36–23.61), p=0.0006]. The prevalence of intronic NRXN1 deletions was not statistically different between cases and controls (p=0.618). The majority (63.2%) of intronic NRXN1 deletion cases had a second rare CNV, a two-fold greater prevalence than for exonic NRXN1 deletion cases (p=0.0035). Conclusions The results support the importance of exons near the 5′ end of NRXN1 in the expression of neurodevelopmental disorders. Intronic NRXN1 deletions do not appear to substantially increase the risk for clinical phenotypes. PMID:27195815

    This article describes the near failure of an information technology (IT) system designed to support a government-funded, primary care-based hepatitis B screening program in New Zealand. Qualitative methods were used to collect data and construct an explanatory model. Multiple incorrect assumptions were made about participants, primary care workflows and IT capacity, software vendor user knowledge, and the health IT infrastructure. Political factors delayed system development and it was implemented untested, almost failing. An intensive rescue strategy included system modifications, relaxation of data validity rules, close engagement with software vendors, and provision of intensive on-site user support. This case study demonstrates that consideration of the social, political, technological, and health care contexts is important for successful implementation of public health informatics projects.

    The importance of instrument firms in the development of psychology, and science in general, should not be underestimated since it would not have been possible for various leading psychologists at the turn of the twentieth century to conduct certain experiments without the assistance of instrument makers, as is often the case today. To illustrate the historical perspective introduced here, the example of Alfred Binet is taken, as he is an interesting case of a psychologist working in close collaboration with various French instrument designers of the time. The objective of this article is twofold: (1) to show the considerable activity carried out by early psychologists to finalize new laboratory instruments in order to develop their research projects; (2) to reassess the work of a major figure in French psychology through his activity as a designer of precision instruments. The development of these new instruments would certainly have been difficult without the presence in Paris of numerous precision instrument manufacturers such as Charles Verdin, Otto Lund, Henri Collin, and Lucien Korsten, on whom Binet successively called in order to develop his projects in the field of experimental psychology.

    Zika virus (ZIKV) is an emerging mosquito-borne flavivirus that can potentially threaten South China. A Chinese family of four returning from Venezuela to China was found to be positive for ZIKV when the youngest son's fever was first detected at an airport immigration inspection. They were isolated temporarily in a local hospital in Enping city, Guangdong province, where their clinical data were recorded and urine and saliva were collected to isolate ZIKV and to obtain viral sequences. All of them except the mother presented mild symptoms of rash and fever. Envelope gene sequences from the father, daughter and son were completely identical. Phylogenetic analysis demonstrated that this strain is similar to several imported strains reported in recent months, which are all clustered into a group isolated from 2015 ZIKA outbreaks in Brazil. Together with the climatic features in Venezuela, New York and Guangdong in February, it can be concluded that our subjects are imported cases from Venezuela. With the same viral sequence being shared between family members, neither direct human-to-human nor vector transmission can be ruled out in this study, but the former seems more likely. Although our subjects had mild illness, epidemiologists and public health officials should be aware of the risk of further expansion of ZIKV transmission by local competent vectors. PMID:27599469

    The work presented here concerns the numerical development and simulation of the flow, pressure patterns and motion of a pair of fingers arranged behind each other and axially aligned in-line. The fingers represent the basic elemental component of a Finger Seal (FS) and form a tight seal around the rotor. Yet their flexibility allows compliance with rotor motion and in a passive-adaptive mode complies also with the hydrodynamic forces induced by the flowing fluid. While the paper does not treat the actual staggered configuration of a finger seal, the inline arrangement represents a first step towards that final goal. The numerical 2-D (axial-radial) and 3-D results presented herein were obtained using a commercial package (CFD-ACE+). Both models use an integrated numerical approach, which couples the hydrodynamic fluid model (Navier-Stokes based) to the solid mechanics code that models the compliance of the fingers.

    Despite a growing body of literature related to church leaders challenging dominant norms of masculinities that may enable the spread of HIV, research on masculinity issues among African church representatives who are policy makers is scarce. The objectives of this study were to explore the perspectives on masculinities held by church representatives within the Ecumenical HIV and AIDS Initiative in Africa (EHAIA) and to identify strategies they used to transform masculinities in their respective churches. Qualitative interviews were carried out with 14 church representatives belonging to the EHAIA International Reference Group. These interviews were analysed using thematic analysis and four themes were identified: "barriers to challenge masculinities" may contribute to the spread of HIV; "counterproductive conservative church leadership" fails to challenge dominant forms of masculinities; "facilitators to challenge masculinities" perceived as slowly changing men and "an evolving hope for gender equality" would be perceived in certain marital relationships. The latter two were viewed as positive approaches resulting from masculinity workshops and male priests disclosing their HIV-positive status. This research highlights strategies that may help male church-goers challenge masculinities, support gender equality and, improve the lives of men and women in the context of HIV. PMID:27681151

    We conducted an assessment of changes in permafrost area and carbon storage simulated by process-based models between 1960 and 2300. The models participating in this comparison were those that had joined the model integration team of the Vulnerability of Permafrost Carbon Research Coordination Network (see http://www.biology.ufl.edu/permafrostcarbon/). Each of the models in this comparison conducted simulations over the permafrost land region in the Northern Hemisphere driven by CCSM4-simulated climate for RCP 4.5 and 8.5 scenarios. Among the models, the area of permafrost (defined as the area for which active layer thickness was less than 3 m) ranged between 13.2 and 20.0 million km2. Between 1960 and 2300, models indicated the loss of permafrost area between 5.1 to 6.0 million km2 for RCP 4.5 and between 7.1 and 15.2 million km2 for RCP 8.5. Among the models, the density of soil carbon storage in 1960 ranged between 13 and 42 thousand g C m-2; models that explicitly represented carbon with depth had estimates greater than 27 thousand g C m-2. For the RCP 4.5 scenario, changes in soil carbon between 1960 and 2300 ranged between losses of 32 Pg C to gains of 58 Pg C, in which models that explicitly represent soil carbon with depth simulated losses or lower gains of soil carbon in comparison with those that did not. For the RCP 8.5 scenario, changes in soil carbon between 1960 and 2300 ranged between losses of 642 Pg C to gains of 66 Pg C, in which those models that represent soil carbon explicitly with depth all simulated losses, while those that do not all simulated gains. These results indicate that there are substantial differences in responses of carbon dynamics between model that do and do not explicitly represent soil carbon with depth in the permafrost region. We present analyses of the implications of the differences for atmospheric carbon dynamics at multiple temporal scales between 1960 and 2300.

    Nucleocytoplasmic trafficking of large macromolecules requires an active transport machinery. In many cases, this is initiated by binding of the nuclear localization signal (NLS) peptide of cargo proteins to importin-α molecules. Fine orchestration of nucleocytoplasmic trafficking is of particularly high importance for proteins involved in maintenance of genome integrity, such as dUTPases, which are responsible for prevention of uracil incorporation into the genome. In most eukaryotes, dUTPases have two homotrimeric isoforms: one of these contains three NLSs and is present in the cell nucleus, while the other is located in the cytoplasm or the mitochondria. Here we focus on the unusual occurrence of a pseudo-heterotrimeric dUTPase in Drosophila virilis that contains one NLS, and investigate its localization pattern compared to the homotrimeric dUTPase isoforms of Drosophila melanogaster. Although the interaction of individual NLSs with importin-α has been well characterized, the question of how multiple NLSs of oligomeric cargo proteins affect their trafficking has been less frequently addressed in adequate detail. Using the D. virilis dUTPase as a fully relevant physiologically occurring model protein, we show that NLS copy number influences the efficiency of nuclear import in both insect and mammalian cell lines, as well as in D. melanogaster and D. virilis tissues. Biophysical data indicate that NLS copy number determines the stoichiometry of complexation between importin-α and dUTPases. The main conclusion of our study is that, in D. virilis, a single dUTPase isoform efficiently reproduces the cellular dUTPase distribution pattern that requires two isoforms in D. melanogaster.

    In the United States during 1981, fourteen state health departments reported a total of 44 imported cases of dengue fever. Most originated in the Caribbean, where dengue type 4 has reached pandemic proportions. Because the mosquito vector for dengue is abundant throughout the southeast and imported cases continue to occur, the possibility exists for indigenous dengue transmission. We report a cluster of imported dengue type 1 cases in Florida, discuss the clinical, epidemiologic, and public health aspects of the disease, and make recommendations as to how clinicians can assist public health officials in minimizing the risk of indigenous dengue transmission in the United States.

    leads to a uniform well-behaved system so that the reactor configuration is in the fundamental mode. In fact, an important property of the oscillation experiments performed in the OSMOSE program is that the neutron flux at the sample location has reached the asymptotic fundamental mode of the MINERVE lattice. This property allows the use of simple spatial methods for the analysis (e.g. a lattice code with axial buckling representing the leakage), without loss of accuracy. The computational challenge is then reduced to the need of an appropriate cross-section processing and of accurate resonance shielding algorithms. In the present study, calculations have been performed to investigate the similarity of the flux spectra at the sample position of different OSMOSE configurations with the neutron energy distributions characterizing existing thermal and fast reactors proposed under the advanced reactor programs Gen-IV, GNEP and NGNP.

In the pathogenesis of HAS are several physiopathological mechanisms involved; of which currently, to name the most important and frequent play a role in increasing adrenaline levels, the renin-angiotensin-aldosterone system and recently, much the participation of insulin resistance and hyperinsulinemia mentioned. These processes lead to an imbalance between the sympathetic and parasympathetic tone, coupled with hypersensitivity sodium trigger one of the pathophysiologic mechanisms of hypertension. SAH is currently defined as finding numbers of older blood pressure 140/90mm Hg. This is one of the diseases that most affect the world population prevalences found in age and gender groups 45 to 55% in men between 45 and 70 years and 45 to 65% in women of the same age group. In 2013 most recent clinical guidelines for treatment and the recommended goals, which has managed to reduce its complications and mortality were published; among which include vascular diseases such as ischemic heart and brain and kidney.

    Monitoring natural populations is often a necessary step to establish the conservation status of species and to help improve management decisions. Nevertheless, many monitoring programs do not effectively address primary sources of variability in monitoring data, which ultimately may limit the utility of monitoring in identifying declines and improving management. To illustrate the importance of taking into account detectability and spatial variation, we used a recently proposed estimator of abundance (superpopulation estimator) to estimate population size of and number of young produced by the Snail Kite (Rostrhamus sociabilis plumbeus) in Florida. During the last decade, primary recovery targets set by the U.S. Fish and Wildlife Service for the Snail Kite that were based on deficient monitoring programs (i.e., uncorrected counts) were close to being met (by simply increasing search effort during count surveys). During that same period, the Snail Kite population declined dramatically (by 55% from 1997 to 2005) and the number of young decreased by 70% between 1992?1998 and 1999?2005. Our results provide a strong practical case in favor of the argument that investing a sufficient amount of time and resources into designing and implementing monitoring programs that carefully address detectability and spatial variation is critical for the conservation of endangered species.

    Coronary sinus atrial septal defects are the rarest defects of the atrial septum comprising <1% of the five different types of atrial septal defects. Despite the widespread adoption of percutaneous device closure of secundum atrial septal defects, the published experience with percutaneous device closure of coronary sinus atrial septal defects is limited to only a few isolated case reports because of uncertainty regarding safety and efficacy. Open-heart surgical repair remains the treatment of choice for coronary sinus atrial septal defects, although this may not be the only treatment option in selected cases. Herein we describe our own experience with two patients with different clinical presentations and our method of successful percutaneous coronary sinus atrial septal defect closure in each. We then present a review of the anatomic spectrum of coronary sinus atrial septal defects along with a review of contemporary surgical and percutaneous device treatment. PMID:24666783

    The evolution of the structure of cyclones and cold fronts over the eastern United States is investigated observationally. Two primary goals of the research are to understand the mechanisms controlling cyclone and frontal evolution across the Appalachian mountains, and to document the presence and importance of mesoscale disturbances during cyclogenesis. First, a climatological survey of seven winter seasons of cyclones and fronts was performed. This study revealed cold fronts are slowed and deformed by the Appalachians, with the cross-frontal pressure and thermal contrasts enhanced considerably across the mountains. In addition, cyclones generally curve northward and dissipate over the mountains while secondary development occurs further south over the lee region. Both upper-level [open quote]forcing[close quote] and low-level thermal structure are important in determining the exact location of redevelopment. Second, a detailed case study was conducted of a cyclone observed during the Genesis of Atlantic Lows Experiment (GALE). The primary cyclone dissipitated over the Northern Appalachians while a secondary lower tropospheric (800-900 mb) cyclone formed over eastern North Carolina. However, strong low-level static stability prevented this disturbance from penetrating to the surface. Instead, cyclogenesis occurred offshore when two mesoscale mid-tropospheric (500 mb) PV maxima, one of which represented an upper level frontal zone, moved over a series of quasi-stationary shallow cloud clusters over the Gulf Stream. Meanwhile, the primary surface cold front was blocked west of the Appalachians, but the mid-level (700-850 mb) front progressed unimpeded across the mountains. Later, a new surface front formed east of the mountains through diabetic processes. These results indicate that future mesoscale models will need to incorporate topography and diabatic processes with increased accuracy.

  7. How do agents represent?

    NASA Astrophysics Data System (ADS)

    Ryan, Alex

    Representation is inherent to the concept of an agent, but its importance in complex systems has not yet been widely recognised. In this paper I introduce Peirce's theory of signs, which facilitates a definition of representation in general. In summary, representation means that for some agent, a model is used to stand in for another entity in a way that shapes the behaviour of the agent with respect to that entity. Representation in general is then related to the theories of representation that have developed within different disciplines. I compare theories of representation from metaphysics, military theory and systems theory. Additional complications arise in explaining the special case of mental representations, which is the focus of cognitive science. I consider the dominant theory of cognition — that the brain is a representational device — as well as the sceptical anti-representational response. Finally, I argue that representation distinguishes agents from non-representational objects: agents are objects capable of representation.

    Although the geographical distribution patterns of microbes have been studied for years, few studies have focused on urban soils. Urbanization may have detrimental effects on the soil ecosystem through pollution discharge and changes in urban climate. It is unclear whether urbanization-related factors have any effect on soil bacterial communities. Therefore we investigated geographical patterns of soil microbial communities in parks in 16 representative Chinese cities. The microbial communities in these 95 soil samples were revealed by 454-pyrosequencing. There were 574,442 effective sequences among the total of 980,019 16S rRNA gene sequences generated, showing the diversity of the microbial communities. Proteobacteria, Actinobacteria, Acidobacteria, Planctomycetes, Chloroflexi and Bacteroidetes were found to be the six dominant phyla in all samples. Canonical correspondence analysis showed that pH, followed by annual average precipitation, annual average temperature, annual average relative humidity and city sunshine hours, Mn and Mg were the factors most highly correlated with the bacterial community variance. Urbanization did have an effect on bacterial community composition of urban park soils but it contributed less to the total variance compared with geographical locations and soil properties, which explained 6.19% and 16.78% of the variance, respectively.

    2014-01-01

    Background Human rabies infection continues to be a significant public health burden globally, and is occasionally imported to high income settings where the Milwaukee Protocol for intensive care management has recently been employed, with limited success in improving survival. Access to molecular diagnostics, pre- and post-mortem, and documentation of pathophysiological responses while using the Milwaukee protocol, can add useful insights for the future of rabies management. Case presentation A 58-year-old British Asian woman was referred to a regional general hospital in the UK with hydrophobia, anxiety and confusion nine weeks after receiving a dog bite in North West India. Nuchal skin biopsy, saliva, and a skin biopsy from the site of the dog bite wound, taken on the day of admission, all demonstrated the presence of rabies virus RNA. Within 48 hours sequence analysis of viral RNA confirmed the diagnosis and demonstrated that the virus was a strain closely related to canine rabies viruses circulating in South Asia. Her condition deteriorated rapidly with increased agitation and autonomic dysfunction. She was heavily sedated and intubated on the day after admission, treated according to a modified Milwaukee protocol, and remained stable until she developed heart block and profound acidosis and died on the eighth day. Analysis of autopsy samples showed a complete absence of rabies neutralizing antibody in cerebrospinal fluid and serum, and corresponding high levels of virus antigen and nucleic acid in brain and cerebrospinal fluid. Quantitative PCR showed virus was also distributed widely in peripheral tissues despite mild or undetectable histopathological changes. Vagus nerve branches in the heart showed neuritis, a probable Negri body but no demonstrable rabies antigen. Conclusion Rapid molecular diagnosis and strain typing is helpful in the management of human rabies infection. Post-mortem findings such as vagal neuritis highlight clinically important effects

    As the world’s fastest spreading vector-borne disease, dengue was estimated to infect more than 390 million people in 2010, a 30-fold increase in the past half century. Although considered to be a non-endemic country, mainland China had 55,114 reported dengue cases from 2005 to 2014, of which 47,056 occurred in 2014. Furthermore, 94% of the indigenous cases in this time period were reported in Guangdong Province, 83% of which were in Guangzhou City. In order to determine the possible determinants of the unprecedented outbreak in 2014, a population-based deterministic model was developed to describe dengue transmission dynamics in Guangzhou. Regional sensitivity analysis (RSA) was adopted to calibrate the model and entomological surveillance data was used to validate the mosquito submodel. Different scenarios were created to investigate the roles of the timing of an imported case, climate, vertical transmission from mosquitoes to their offspring, and intervention. The results suggested that an early imported case was the most important factor in determining the 2014 outbreak characteristics. Precipitation and temperature can also change the transmission dynamics. Extraordinary high precipitation in May and August, 2014 appears to have increased vector abundance. Considering the relatively small number of cases in 2013, the effect of vertical transmission was less important. The earlier and more frequent intervention in 2014 also appeared to be effective. If the intervention in 2014 was the same as that in 2013, the outbreak size may have been over an order of magnitude higher than the observed number of new cases in 2014.The early date of the first imported and locally transmitted case was largely responsible for the outbreak in 2014, but it was influenced by intervention, climate and vertical transmission. Early detection and response to imported cases in the spring and early summer is crucial to avoid large outbreaks in the future. PMID:26863623

    The evolution of the structure of cyclones and cold fronts over the eastern United States is investigated observationally. Two primary goals of the research are to understand the mechanisms controlling cyclone and frontal evolution across the Appalachian mountains, and to document the presence and importance of mesoscale disturbances during cyclogenesis. The research was accomplished in two phases. First, a climatological survey of seven winter seasons of cyclones and fronts was performed. This study revealed that cold fronts are slowed and deformed by the Appalachians, with the cross-frontal pressure and thermal contrasts enhanced considerably across the mountains. In addition, cyclones generally curve northward and dissipate over the mountains while secondary development occurs further south over the lee region. Both upper-level "forcing" and low-level thermal structure are important in determining the exact location of redevelopment. Second, a detailed case study was conducted of a cyclone observed during the Genesis of Atlantic Lows Experiment (GALE). The primary cyclone dissipated over the northern Appalachians while a secondary lower tropospheric (800-900 mb) cyclone formed over eastern North Carolina. However, strong low-level static stability prevented this disturbance from penetrating to the surface. Instead, cyclogenesis occurred offshore when two mesoscale mid-tropospheric (500 mb) PV maxima, one of which represented an upper level frontal zone, moved over a series of quasi-stationary shallow cloud clusters over the Gulf Stream. Meanwhile, the primary surface cold front was blocked west of the Appalachians, but the mid-level (700-850 mb) front progressed unimpeded across the mountains. Later, a new surface front formed east of the mountains through diabatic processes. Both surface heating and evaporation played important roles in the frontal redevelopment. These results indicate that future mesoscale models will need to incorporate topography and

    2016-10-01

    In this paper, we present a study of the signs and the magnitudes of the errors of theoretical binding energies, BE's, of the C(1s) and O(1s) core-levels compared to BE's measured in X-Ray photoemission, XPS, experiments. In particular, we explain the unexpected sign of the error of the Hartree-Fock C(1s) BE, which is larger than experiment, in terms of correlation effects due to the near degeneracy of the CO(1π) and CO(2π) levels and show how taking this correlation into account leads to rather accurate predicted BE's. We separate the initial state contributions of this near degeneracy, present for the ground state wavefunction, from the final state near degeneracy effects, present for the hole state wavefunctions. Thus, we are able to establish the importance for the core-level BE's of initial state charge redistribution due to the π near-degeneracy. While the results for CO are interesting in their own right, we also consider whether our conclusions for CO are relevant for the analysis of XPS spectra of a wider range of molecules.

    The authors report on two cases of suspected Munchausen by proxy syndrome. In a 3-year-old boy, clinical toxicological analyses produced suspicious clues that an antidepressant had been administered, which could not be verified by forensic toxicological investigations. In a 13-month-old boy, the mother was also suspected of having poisoned the child. Initial clinical toxicological examinations failed to explain the observed symptoms (unclear unconsciousness, narrowed pupils). While in the first case, the incorrect interpretation of findings by a laboratory without forensic experience resulted in suspicions against the mother, the cause for the observed symptoms in the second case could be proved by complex analyses not performed before and the suspicion that the clinical picture had been intentionally brought about could be cleared up (use of an antitussive containing clobutinol). The two reports show that especially in cases with a potential forensic background, adequately qualified forensic laboratories with a broad spectrum of analytical methods should be involved.

    Probabilistic graphical models are being used widely in artificial intelligence, for instance, in diagnosis and expert systems, as a unified qualitative and quantitative framework for representing and reasoning with probabilities and independencies. Their development and use spans several fields including artificial intelligence, decision theory and statistics, and provides an important bridge between these communities. This paper shows by way of example that these models can be extended to machine learning, neural networks and knowledge discovery by representing the notion of a sample on the graphical model. Not only does this allow a flexible variety of learning problems to be represented, it also provides the means for representing the goal of learning and opens the way for the automatic development of learning algorithms from specifications.

  1. Barite: a case study of import reliance on an essential material for oil and gas exploration and development drilling

    2015-01-01

    Domestic barite production was about 670,000 metric tons (t) in 2012, equivalent to about 20 percent of the domestic drilling industry’s barite demand. Mine production for the United States in 2012 was about one-third of what was produced in 1980. In 2012, barite imported from China was approximately 2.2 million t and comprised about 77 percent of total barite imports and about 70 percent of the barite used in domestic drilling. Barite from India (14 percent), Morocco (6 percent) and Mexico (2 percent) comprised the bulk of the remaining total import balance; drilling applications consumed nearly all barite imported from these three countries.

    Between-session interventions, or homework, are crucial to a range of psychological therapies, including cognitive behavior therapy (CBT). Therapeutic interventions often involve experiencing emotions and situations, or examining strongly held views about their problems, that clients can find distressing. Hence, the clinician faces a particular challenge in collaborating with the client to carry out these interventions between sessions. In this article, we convey how this process in CBT requires not only a consideration of the theoretically meaningful determinants of adherence behavior but also a sophisticated cognitive case conceptualization. Using case material, we illustrate the interplay between in-session design, planning, and review of between-session interventions and the conceptualization. We also include a distinction between generic elements of the therapeutic relationship and CBT-specific elements. The case material also attends to the person of the therapist, and his or her own cognitive and emotional reactions occurring throughout the process of discussing between-session interventions.

    The Factor V Leiden mutation is associated with ischemic stroke in children, but not in adults. Whether it is associated with ischemic stroke in young adults, however, is uncertain. To address this issue, we performed a meta-analysis of 18 case-control studies of ischemic stroke in adults ≤ 50 years of age published before June 2009. Across all studies, Factor V Leiden was detected in 154 of 2,045 cases (7.5%) and 217 of 5,307 controls (4.1%), yielding a fixed effect odds ratio of 2.00 (95% CI: 1.59–2.51). However, further analyses revealed substantial heterogeneity among these studies (p=0.005 for Q-test of heterogeneity). Hypothesizing that this heterogeneity could be related to differences among studies in case selection criteria, we stratified the meta-analysis into studies for which case samples were enriched or not enriched to include cases having an increased likelihood of prothrombotic genetic involvement (“selected” ischemic stroke studies, n = 9) and those that recruited cases from consecutive neurology referrals or hospitalizations (“unselected” ischemic stroke studies, n = 8). Among the nine “selected” ischemic stroke studies, Factor V Leiden was more strongly associated with stroke [OR = 2.73 (95% CI: 1.98–3.75)], whereas among the eight “unselected” ischemic stroke studies, the association between Factor V Leiden and stroke was substantially weaker [OR=1.40 (95% CI: 0.998–1.95)]. This difference was found to be statistically significant (p = 0.003 for Woolf’s test for heterogeneity). We conclude that Factor V Leiden is associated with ischemic stroke in young adults, particularly in patient populations where there is an increased clinical suspicion of prothrombotic state.

    In October 2013, a locally-acquired case of dengue virus (DENV) infection was reported in Western Australia (WA) where local dengue transmission has not occurred for over 70 years. Laboratory testing confirmed recent DENV infection and the case demonstrated a clinically compatible illness. The infection was most likely acquired in the Pilbara region in the northwest of WA. Follow up investigations did not detect any other locally-acquired dengue cases or any known dengue vector species in the local region, despite intensive adult and larval mosquito surveillance, both immediately after the case was notified in October 2013 and after the start of the wet season in January 2014. The mechanism of infection with DENV in this case cannot be confirmed. However, it most likely followed a bite from a single infected mosquito vector that was transiently introduced into the Pilbara region but failed to establish a local breeding population. This case highlights the public health importance of maintaining surveillance efforts to ensure that any incursions of dengue vectors into WA are promptly identified and do not become established, particularly given the large numbers of viraemic dengue fever cases imported into WA by travellers returning from dengue-endemic regions.

The obstacles for its diagnosis using the standard microscopy technique and the need to improve its detection are discussed.

  10. Representing properties locally.

    PubMed

    Solomon, K O; Barsalou, L W

    2001-09-01

    Theories of knowledge such as feature lists, semantic networks, and localist neural nets typically use a single global symbol to represent a property that occurs in multiple concepts. Thus, a global symbol represents mane across HORSE, PONY, and LION. Alternatively, perceptual theories of knowledge, as well as distributed representational systems, assume that properties take different local forms in different concepts. Thus, different local forms of mane exist for HORSE, PONY, and LION, each capturing the specific form that mane takes in its respective concept. Three experiments used the property verification task to assess whether properties are represented globally or locally (e.g., Does a PONY have mane?). If a single global form represents a property, then verifying it in any concept should increase its accessibility and speed its verification later in any other concept. Verifying mane for PONY should benefit as much from having verified mane for LION earlier as from verifying mane for HORSE. If properties are represented locally, however, verifying a property should only benefit from verifying a similar form earlier. Verifying mane for PONY should only benefit from verifying mane for HORSE, not from verifying mane for LION. Findings from three experiments strongly supported local property representation and ruled out the interpretation that object similarity was responsible (e.g., the greater overall similarity between HORSE and PONY than between LION and PONY). The findings further suggest that property representation and verification are complicated phenomena, grounded in sensory-motor simulations.

    Acute kidney injury is an unfortunate complication of acyclovir therapy secondary to crystal-induced nephropathy. It is characterized by a decrease in renal function that develops within 24–48 hours of acyclovir administration indicated by a rapid rise in the serum creatinine. Failure to quickly realize this as an etiology of acute kidney injury can lead to excessive morbidity to the patient. The case described in this vignette is an example of the clinical manifestation of acyclovir crystal obstructive nephrotoxicity. We will briefly discuss the pathophysiology, diagnosis, prevention, and management of patients that present with acyclovir nephrotoxicity. PMID:20862348

    Osteochondroma is a rare tumor of the mandibular condyle. Much confusion seems to exist in the literature in differentiating these tumors from chondromas as well as condylar hyperplasias. Due to considerable overlapping features between chondromas and condylar hyperplasia, it is likely to get misdiagnosed, thereby resulting in inadvertent errors in the treatment. A case report of a 35 year old male patient with mandibular deviation and malocclusion is presented here. He initially went unnoticed for features of an osteochondroma of the mandibular condyle but was subsequently treated for the same. PMID:25737946

    This report describes the case of a man who developed fatal sigmoid volvulus that was identified on postmortem radiography before forensic autopsy. Postmortem radiography is useful for visualizing the body prior to autopsy. We discuss postmortem multidetector computed tomography that was tailored for optimum image quality to allow reconstruction of the fatal findings in multiple axes and in three dimensions, helping to pinpoint the anatomical sites of interest. This involves techniques such as manipulation of the scanning beam pitch and overlapping CT section acquisition. These techniques are best performed by personnel with CT technology training.

  15. The representative animal

    PubMed Central

    1994-01-01

    The anthropocentric approach to the study of animal behavior uses representative nonhuman animals to understand human behavior. This approach raises problems concerning the comparison of the behavior of two different species. The datum of behavior analysis is the behavior of humans and representative animal phenotypes. The behavioral phenotype is the product of the ontogeny and phylogeny of each species, and this requires that contributions of genotype as well as behavioral history to experimental performance be considered. Behavior analysis tends to favor the ontogenetic over the phylogenetic component, yet both components are responsible for the performance of each individual animal. This paper raises questions about the role of genotype variables in the use of representative animals to understand human behavior. Examples indicating the role of genotype in human behavior are also discussed. The final section of the paper deals with considerations of genotype in the design of animal experiments. PMID:22478186

    More affordable international travel, global trade and commerce, and the exporting of labor have all contributed to international population mobility. Furthermore, population migration leads to the incidence or recurrence of once-controlled diseases. Evidence shows that the popularity of travel can impact health through imported infections and illness. Imported cutaneous myiasis, a type of skin lesion, has attracted the attention of the current authors. This condition often occurs among travelers and it has been reported in several non-endemic countries. However, diagnosis of myiasis and identification of the larvae are difficult. Advances in molecular detection techniques could provide a new way to identify larvae. This study used sequencing of the 28S rRNA gene and morphology to identify the larva infesting the upper arm of a Chinese woman returning from Uganda. The larva was identified as Cordylobia anthropophaga (C. anthropophaga) and the sequences were submitted to GenBank (accession number: KM506761). As foreign interaction increases, imported health problems may become more common in China. Knowledge about various pathogens needs to be increased and molecular methods need to be used to accurately identify those pathogens.

    Researchers have argued that indigenous peoples preferably use the most apparent plant species, particularly for medicinal uses. However, the association between the ecological importance of a species and its usefulness remains unclear. In this paper we quantify such association for six use categories (firewood, construction, materials, food, medicines and other uses). We collected data on the uses of 58 tree species, as reported by 93 informants in 22 villages in the Tsimane’ territory (Bolivian Amazon). We calculated the ecological importance of the same species by deriving their importance value index (IVI) in 48 0.1-ha old-growth forest plots. Matching both data sets, we found a positive relation between the IVI of a species and its overall use value (UV) as well as with its UV for construction and materials. We found a negative relation between IVI and UV for species that were reportedly used for medicine and food uses, and no clear pattern for the other categories. We hypothesize that species used for construction or crafting purposes because of their physical properties are more easily substitutable than species used for medicinal or edible purposes because of their chemical properties.

Victims were predicted to be more negatively judged when they consented to sex than when they did not and when they were lied to than when they were not. Two hundred and seventy-six respondents read a sexual abuse depiction in which the perpetrator's disclosure about his age (being honest from the outset, lying, or refusing to disclose when questioned) and the final outcome of the meeting (consensual verses nonconsensual sexual intercourse) were varied between subjects. Respondents then completed a 17-item attribution scale. ANOVAs revealed broad support for the predictions. Results have implications for education about cybercrime.

  1. The importance of functional impairment to mental health outcomes: A case for reassessing our goals in depression treatment research

    McKnight, Patrick E.; Kashdan, Todd B.

    2009-01-01

    Outcomes in depression treatment research include both changes in symptom severity and functional impairment. Symptom measures tend to be the standard outcome but we argue that there are benefits to considering functional outcomes. An exhaustive literature review shows that the relationship between symptoms and functioning remains unexpectedly weak and often bidirectional. Changes in functioning often lag symptom changes. As a result, functional outcomes might offer depression researchers more critical feedback and better guidance when studying depression treatment outcomes. The paper presents a case for the necessity of both functional and symptom outcomes in depression treatment research by addressing three aims–1) review the research relating symptoms and functioning, 2) provide a rationale for measuring both outcomes, and 3) discuss potential artifacts in measuring functional outcomes. The three aims are supported by an empirical review of the treatment outcome and epidemiological literatures. PMID:19269076

    Weblogs (blogs), together with podcasts and wikis are part of the larger body of next-generation communication applications dubbed "web 2.0." Within the specific area of health care, little attention has been devoted to understanding what applications are available to the lay public and how these are being used. In this study, a literature review on blogs and blogging practices was conducted, followed by case study analyses of two separate sites that use blogging tools to help patients and other lay web end-users record health-related experiences. This paper explores the diverse purposes for which blogging applications can be (or are being) used in relation to health and introduces the idea of "health goal-oriented" blogging. The discussion focuses on relevant informatics questions that arise with respect to the use of blogs and makes suggestions for subsequent research.

    Introduction The factors that affect the development of children with and without hearing disabilities are similar, provided their innate communication abilities are taken into account. Parents need to mourn the loss of the expected normally hearing child, and it is important that parents create bonds of affection with their child. Objective To conduct a postevaluation of the development and cognition of 20 candidates for cochlear implants between 1 and 13 years of age and to observe important factors in their development. Methods The following instruments were used in accordance with their individual merits: interviews with parents; the Vineland Social Maturity Scale; the Columbia Maturity Scale; free drawings; Bender and Pre-Bender testing; and pedagogical tests. Results The results are described. Conclusion Parental acceptance of a child's deafness proved to be the starting point for the child's verbal or gestural communication development, as well as for cognitive, motor, and emotional development. If the association between deafness and fine motor skills (with or without multiple disabilities) undermines the development of a child's speech, it does not greatly affect communication when the child interacts with his or her peers and receives maternal stimulation. Overprotection and poor sociability make children less independent, impairs their development, and causes low self-esteem. Further observational studies are warranted to determine how cochlear implants contribute to patient recovery. PMID:25992122

    2009-09-01

    Increased attention to childrens' special position within poverty measurement resulted in the development of various child poverty approaches in the last decade. Analysis shows that their development processes involve a similar set of steps and decisions, predominantly taken in the same sequence. However, it also becomes apparent that many of these decisions are made implicitly rather than explicitly, resulting in unclear and non-transparent underlying constructs. Consequently, child poverty approaches often lack a solid and robust foundation and are misinterpreted and misunderstood when used for analytical and policy purposes. This paper distills a generic construction process from the analysis of existing child poverty approaches, presenting a tool for clear and transparent development of such approaches. It is then applied to the case of Vietnam, using household survey data, to illustrate its practical use and develop a Vietnam-specific child poverty approach. Findings suggest that 37% of all children are poor, whilst observing a large rural-urban divide but no significant differences between boys and girls.

    Nutcracker syndrome (NCS) is the name given to entrapment of the left renal vein (LRV) between the aorta and superior mesenteric artery (SMA). The aim of the study was to review current research and clarify the most common clinical image of the syndrome. A systematic review of PubMed and EBSCO databases was performed. Articles included in the study had to meet the following criteria: publication between 1980 and 2014, a detailed report on patient symptoms and laboratory test results, medical imaging confirmation of LRV entrapment diagnosis. Fifty-five publications which met the inclusion criteria provided the final database containing 112 cases. The male-female distribution was equal, the mean age on diagnosis for the whole group was 26.47±13.77years. Diagnosis was made earlier in males (23.59±13.09) than females (29.34±13.93). The following frequency of symptoms was noted: 78.57% for haematuria, 38.39% for left flank pain, 35.71% for varicocele in males, 30.36% for proteinuria and 13.39% for anaemia. NCS diagnosis was made earlier if proteinuria occurred as one of the symptoms (P<0.001). Anemia occurred more often in older patients (P=0.0128). NCS was diagnosed in younger age in patients with varicocele (P=0.037). Although NCS is not a common diagnosis, it should be taken into consideration, particularly in hematuria of unknown origin and varicocele.

    Groundwater is an important source of water supply, especially for areas lacking in surface water. Many countries have delineated recharge areas to protect groundwater resources. If the areas were not protected, the groundwater quantity and quality would be affected because of human activities. To understand the importance of recharge areas, this study applied MODFLOW and MODPATH to qualify the effects after a recharge area was polluted. This study developed a steady state groundwater simulation model consisting of three aquifers to simulate the groundwater flow of Choshuihsi Alluvial Fan. The simulation heads from MODFLOW were used as input into MODPATH to estimate concentration field. The initial condition of MODPATH was that the contamination particles were distributed on the surface of the shallow aquifer inside the recharge area and the simulation period was set as 200 years. Results shows that parts of the particles flow into the deep aquifers and parts of them flow into the distal-fan of the shallow aquifer 200 years. The result also shows that 22.2%, 45.3% and 22.4% of the three aquifers were polluted, respectively. The second aquifer was polluted widest, this is because the confining bed at mid-fan and distal-fan between first aquifer and second aquifer were well developed. This caused the recharge of second aquifer to rely on the lateral recharge from recharge area and so does third aquifer. Furthermore, the large amount of pumpage at distal-fan of second aquifer caused groundwater level to lower. This situation makes a higher head difference between top-fan and distal-fan of second aquifer. Therefore, the contamination from recharge area has more opportunity to be transported to distal-fan.

    Imported dengue is increasingly observed in non endemic countries. We report a retrospective study of 44 cases of dengue fever diagnosed in nine french university hospitals between 1994 and 1997. The patients were aged between 13 and 67 years. Most of them were tourists and had been traveling for a few weeks, in French West Indies and French Guyana (18), South-East Asia (10), India (7) or Polynesia (4). Only, two contracted the disease in Africa. The onset of symptoms preceded the return or followed it within 7 days. The most frequent clinical presentation was a febrile and painful syndrome. Cutaneous manifestations (rash or macular exanthem) were observed in 59% of cases, digestive symptoms in 50%, pharyngitis and/or cough in 25%, microadenopathy in 20%, moderate mucous haemorrhagic manifestations in 16% and neuropsychiatric manifestations in 14%. The common biological abnormalities were thrombocytopenia (84%), leukopenia (59%), and elevated transminases (57%). The diagnosis, orientated by negativity of malaria smears, the knowledge of an epidemic in the visited country, or occurrence of similar cases in the entourage, were argued by serological results: presence of anti-DEN IgM in 25 cases, serological conversion (anti- DEN IgG) in 7 cases or very high seropositivity (anti-DEN IgG > 1/1280) in 12 cases. No virus isolation was obtained.

    Background. The Middle East respiratory syndrome coronavirus (MERS-CoV) was discovered September 2012 in the Kingdom of Saudi Arabia (KSA). The first US case of MERS-CoV was confirmed on 2 May 2014. Methods. We summarize the clinical symptoms and signs, laboratory and radiologic findings, and MERS-CoV–specific tests. Results. The patient is a 65-year-old physician who worked in a hospital in KSA where MERS-CoV patients were treated. His illness onset included malaise, myalgias, and low-grade fever. He flew to the United States on day of illness (DOI) 7. His first respiratory symptom, a dry cough, developed on DOI 10. On DOI 11, he presented to an Indiana hospital as dyspneic, hypoxic, and with a right lower lobe infiltrate on chest radiography. On DOI 12, his serum tested positive by real-time reverse transcription polymerase chain reaction (rRT-PCR) for MERS-CoV and showed high MERS-CoV antibody titers, whereas his nasopharyngeal swab was rRT-PCR negative. Expectorated sputum was rRT-PCR positive the following day, with a high viral load (5.31 × 106 copies/mL). He was treated with antibiotics, intravenous immunoglobulin, and oxygen by nasal cannula. He was discharged on DOI 22. The genome sequence was similar (>99%) to other known MERS-CoV sequences, clustering with those from KSA from June to July 2013. Conclusions. This patient had a prolonged nonspecific prodromal illness before developing respiratory symptoms. Both sera and sputum were rRT-PCR positive when nasopharyngeal specimens were negative. US clinicians must be vigilant for MERS-CoV in patients with febrile and/or respiratory illness with recent travel to the Arabian Peninsula, especially among healthcare workers. PMID:25100864

    Many important atmospheric aerosol processes depend on the chemical composition of the aerosol, e.g. water uptake and particle cloud interactions. Atmospheric ageing processes, such as oxidation reactions, significantly and continuously change the chemical composition of aerosol particles throughout their lifetime. These ageing processes are often poorly understood. In this study we utilize an aerosol flow tube set up and an ultra-high resolution mass spectrometer to explore the effect of relative humidity (RH) in the range of <5-90% on the ozonolysis of maleic acid aerosol which is employed as model organic aerosol system. Due to the slow reaction kinetics relatively high ozone concentrations of 160-200 ppm were used to achieve an appreciable degree of oxidation of maleic acid. The effect of oxidative ageing on the hygroscopicity of maleic acid particles is also investigated using an electrodynamic balance and thermodynamic modelling. RH has a profound effect on the oxidation of maleic acid particles. Very little oxidation is observed at RH < 50% and the only observed reaction products are glyoxylic acid and formic acid. In comparison, when RH > 50% there are about 15 oxidation products identified. This increased oxidation was observed even when the particles were exposed to high humidities long after a low RH ozonolysis reaction. This result might have negative implications for the use of water as an extraction solvent for the analysis of oxidized organic aerosols. These humidity-dependent differences in the composition of the ozonolyzed aerosol demonstrate that water is both a key reactant in the oxidation scheme and a determinant of particle phase and hence diffusivity. The measured chemical composition of the processed aerosol is used to model the hygroscopic growth, which compares favourably with water uptake results from the electrodynamic balance measurements. A reaction mechanism is presented which takes into account the RH dependent observations. This

    Malaria endemic status of our countries supports avoiding malaria screening for the blood qualification. But this attitude makes young children, pregnant women and people without semi-immunity incur a high risk of malaria. The goal of the survey was to value the reality and the importance of transfusion-transmitted malaria and to assess its determining factors. The study included 141 packed-red-cells units transfused to 77 hospitalized recipients, not suffering from malaria and not having been transfused the last two weeks. Every packed-red-cells assigned to a patient was tested for malaria before use. Thick and thin blood film were performed 96hours after transfusion. A clinical follow-up was undertaken as well as in the hospital and at home after release. In all, 13.47% of the transfused packed-red-cells were positive for the thick blood film. Plasmodium research in patients was negative 96hours after transfusion, even in the 19 patients who had received parasitized blood units! The home follow-up had permitted to note that 15.78% of blood recipients had developed clinical malaria. Parasitic density ≥240 parasites/mm(3) seems to be a determining factor. Transfusion-transmitted malaria is a reality we ought to consider. Introduction of malaria screening in donated blood qualification testings simultaneously with a framing of the blood donors appear the lasting solution to hope in the future to limit the waited excessive blood evictions.

    It has been widely hypothesized that catastrophic floods can play an important role in the development of a young and growing delta. This study examines the nature and rate of sediment deposition in the Wax lake delta in the Atchafalaya Basin of Louisiana during the Mississippi River flood of from April, 2011 to June, 2011. We hypothesize that the deposition rate that results from large scales floods in the Mississippi/Atchafalaya river outlets have a greater impact in the Wax lake delta development than the deposition rates that result from typical yearly sedimentation. Preliminary results from the cosmogenic 7Be counts from sediment collected from the delta show distinct regional and local sediment deposition patterns during the flood, and rates that are significantly higher when compared to the sedimentation rate of the last few decades. This application of cosmogenic 7Be to distinguish the sediment deposition rate provides a first-order understanding of the deltaic evolution and stratigraphic sequence development in a high-discharge setting.

  15. Importance of strategic management in the implementation of private medicine retailer programmes: case studies from three districts in Kenya

    2010-01-01

    Abstract Background The home-management of malaria strategy seeks to improve prompt and effective anti-malarial drug use through the informal sector, with a potential channel being the Private Medicine Retailers (PMRs). Previous evaluations of PMR programmes focused on their impact on retailer knowledge and practices, with limited evidence about the influence of implementation processes on the impacts at scale. This paper examines how the implementation processes of three PMR programmes in Kenya, each scaled up within a district, contributed to the outcomes observed. These were a Ministry of Health programme in Kwale district; and two programmes supported by non-governmental organizations in collaboration with government in Kisii Central and Bungoma districts. Methods The research methods included 24 focus group discussions with clients and PMRs, 19 in-depth interviews with implementing actors, document review and a diary of events. The data were analysed using the combination of a broad policy analysis framework and more specific scaling up/diffusion of innovations frameworks. Results The Kisii programme, a case study of successful implementation, was underpinned by good relationships between district health managers and a “resource team”, supported by a memorandum of understanding which enabled successful implementation. It had flexible budgetary and decision making processes which were responsive to local contexts, and took account of local socio-economic activities. In contrast, the Kwale programme, which had implementation challenges, was characterised by a complex funding process, with lengthy timelines, that was tied to the government financial management system which constrained implementation Although there was a flexible funding system in Bungoma, a perceived lack of transparency in fund management, inadequate management of inter-organisational relationships, and inability to adapt and respond to changing circumstances led to implementation

    The magnetic mineralogy of soils and paleosols is a rich archive of paleoclimatic information. However, efforts to quantify parameters such as mean annual precipitation (MAP) or temperature using environmental magnetism are still in their infancy. Inherent in any magnetic paleoclimate proxy is a fundamental understanding of how the concentration, grain size distribution, and composition of iron oxides and oxyhydroxides formed during pedogenesis reflect the climatic conditions that prevailed during soil formation. The influence of diagenetic processes on magnetic minerals, particularly for paleosols in pre-Quaternary systems, may compromise our ability to recover a climatic signal due to mineral alterations or incomplete preservation. Here, we evaluate the rock magnetic properties of non-loessic paleosols across the Paleocene-Eocene Thermal Maximum (PETM, ~55.5 Ma) in the Bighorn Basin, WY. Our study compares data from nine paleosol layers sampled from outcrop, exposed to surficial weathering, as well as the equivalent paleosol layers sampled from drill core, all of which are preserved below a pervasive oxidative weathering front and presumably unweathered. Despite variation in magnetic properties within paleosol layers, there is no clear change in magnetic mineralogy that we can attribute to surficial weathering. Further, common measures of magnetic enhancement in susceptibility and remanence show similar trends across the PETM, in both core and outcrop, when compared to estimates of MAP from geochemical weathering indices. Taken together, our record suggests that the magnetic minerals preserved in ancient paleosols retain at least qualitative information about paleoprecipitation and could be an important source of information for paleoclimatic studies. Further work to improve our understanding of the relative preservation of various pedogenic components in paleosols will ultimately determine their viability as quantitative indicators of paleoclimate.

    The sedative-hypnotic benzodiazepine flunitrazepam (FZ) is abused worldwide. The purpose of our study was to investigate violence and anterograde amnesia following intoxication with FZ, and how this was legally evaluated in forensic psychiatric investigations with the objective of drawing some conclusions about the importance of urine sample in a case of a suspected intoxication with FZ. The case was a 23-year-old male university student who, intoxicated with FZ (and possibly with other substances such as diazepam, amphetamines or cannabis), first stabbed an acquaintance and, 2 years later, two friends to death. The police investigation files, including video-typed interviews, the forensic psychiatric files, and also results from the forensic autopsy of the victims, were compared with the information obtained from the case. Only partial recovery from anterograde amnesia was shown during a period of several months. Some important new information is contained in this case report: a forensic analysis of blood sample instead of a urine sample, might lead to confusion during police investigation and forensic psychiatric assessment (FPA) of an FZ abuser, and in consequence wrong legal decisions. FZ, alone or combined with other substances, induces severe violence and is followed by anterograde amnesia. All cases of bizarre, unexpected aggression followed by anterograde amnesia should be assessed for abuse of FZ. A urine sample is needed in case of suspected FZ intoxication. The police need to be more aware of these issues, and they must recognise that they play a crucial role in an assessment procedure. Declaring FZ an illegal drug is strongly recommended.

    Chikungunya fever (CHIKF) is currently distributed in Africa and in South and Southeast Asia; outbreaks have occurred periodically in the region over the past 50 years. After a large outbreak had occurred in countries in the western Indian Ocean region in 2005, several countries reported cases of CHIKF from travelers who had visited affected areas. In Japan, there have been only 15 cases of CHIKF patients so far, according to the National Institute of Infectious Diseases. Therefore, to evaluate the clinical and radiological features associated with the disease, we describe 6 imported cases of CHIKF. All of the patients had had prolonged arthralgia on admission to our hospital, and diagnosis was confirmed with specific antibodies by using an IgM-capture enzyme-linked immunoassay and a plaque reduction neutralizing antibody assay. Magnetic resonance imaging (MRI) of one patient revealed erosive arthritis and tenosynovitis during the convalescence stage. Clinicians should be aware of the late consequences of infection by the chikungunya virus (CHIKV) and recognize the possible association of subacute and chronic arthritis features. In addition, competent vectors of CHIKV, Aedes aegypti, can now be found in many temperate areas of the eastern and western hemispheres, including Japan. This fact raises concern that the virus could be introduced and become established in these areas. This necessitates an increased awareness of the disease, because imported cases are likely to contribute to the spread of CHIKV infection wherever the competent mosquito vectors are distributed.

    Roughness measurements are of main importance in characterizing the optical properties of papers and prints. However, there is a lack of knowledge concerning the surface size and the spacing of the measures to be optically representative of the surface structure. Paper is a multiscale medium, and the roughness parameters extracted from the three-dimensional (3D) surface mapping depend on both the size and the step of discretization. Ray tracing, based on optical geometry, could be a tool to model the light reflection on a paper surface. Ray-tracer software was therefore developed. A new optical device was used to measure paper surface topographies at various scales. Ray tracing simulations were then performed on the 3D mapping and compared to the scattering indicatrix obtained with a classical goniometer. Hence it was possible to identify a magnification for various types of paper grades that is optically representative of the specular gloss.

    The relative importance of ecological vs. non-ecological factors for the origin and maintenance of species is an open question in evolutionary biology. Young lineages--such as the distinct genetic groups that make up the ranges of many northern species--represent an opportunity to study the importance of ecological divergence during the early stages of diversification. Yet, few studies have examined the extent of niche divergence between lineages in previously glaciated regions and the role of ecology in maintaining the contact zones between them. In this study, we used tests of niche overlap in combination with ecological niche models to explore the extent of niche divergence between lineages of the long-toed salamander (Ambystoma macrodactylum Baird) species complex and to determine whether contact zones correspond to (divergent) niche limits. We found limited evidence for niche divergence between the different long-toed salamander lineages, substantial overlap in the predicted distribution of suitable climatic space for all lineages and range limits that are independent of niche limits. These results raise questions as to the importance of ecological divergence to the development of this widespread species complex and highlight the potential for non-ecological factors to play a more important role in the maintenance of northern taxa.

    Niche processes and other spatial processes, such as dispersal, may simultaneously control beta diversity, yet their relative importance may shift across spatial and temporal scales. Although disentangling the relative importance of these processes has been a continuing methodological challenge, recent developments in multi-scale spatial and temporal modeling can now help ecologists estimate their scale-specific contributions. Here we present a statistical approach to (1) detect the presence of a space-time interaction on community composition and (2) estimate the scale-specific importance of environmental and spatial factors on beta diversity. To illustrate the applicability of this approach, we use a case study from a temperate forest understory where tree seedling abundances were monitored during a 9-year period at 40 permanent plots. We found no significant space-time interaction on tree seedling composition, which means that the spatial abundance patterns did not vary over the study period. However, for a given year the relative importance of niche processes and other spatial processes was found to be scale-specific. Tree seedling abundances were primarily controlled by a broad-scale environmental gradient, but within the confines of this gradient the finer scale patchiness was largely due to other spatial processes. This case study illustrates that these two sets of processes are not mutually exclusive and can affect abundance patterns in a scale-dependent manner. More importantly, the use of our methodology for future empirical studies should help in the merging of niche and neutral perspectives on beta diversity, an obvious next step for community ecology.

The importance that clients placed on selected issues related to their care (e.g., privacy, daily routines, activities, involvement of family in care, the trade-off between freedom and safety) varied as did the specific content of those issues. Associations were found between the content and strength of preferences. The work has implications for research and practice.

    This case study attempts to quantify the amount and timing of the import, export and through-flow of old ice in the Peary Channel-Sverdrup Channel area of the northern Canadian Arctic Archipelago during the period 1998-2005. The study combines quantitative weekly area-averaged ice coverage evaluations from the Canadian Ice Service (CIS) Digital Archive with detailed analysis of RADARSAT imagery and ice-motion results from the CIS ice-motion algorithm. The results show that in 1998 more than 70% of the old ice in Peary-Sverdrup was lost, half by melt and export to the south and the other half by export north into the Arctic Ocean, and that no Arctic Ocean old ice was imported into Peary-Sverdrup. A net import of 10% old ice was seen in 1999, with some indication of through-flow into southern channels. In 2000, no net import of old ice occurred in Peary-Sverdrup, but there was significant through-flow, with evidence of old ice reaching the Northwest Passage by November. Full recovery of the old-ice regime was complete by the end of 2001. More than two-thirds of the recovery was due to the in situ formation of second-year ice. Conditions in the following 3 years were near normal.

    Cutaneous dirofilariasis is a parasitic disease caused by the mosquito-borne filarial nematodes Dirofilaria (Nochtiella) repens, living in the subcutaneous tissue of dogs, cats, wild carnivores, and humans. Cases have been recently reported also from Germany, Czech Republic, Hungary, Ukraine, Russia, Austria, Switzerland, France, The Netherlands, and the Middle East. D. repens is not widely known to cause chronic pruritic dermatitis in animals. Dermatological signs observed in 100 canine clinic cases were pruritus (100%), erythema (79%), papulae (62%), focal or multifocal alopecia (55%), hyperkeratosis (18%), crusting (14%), nodules (12%), acantosis (5%), and eczema (3%). Signs other than dermatological were conjunctivitis (46%), anorexia (35%), vomiting (26%), fever (25%), lethargy (20%), and lymph-adenomegaly (10%). A case imported from Italy to Dubai is described. The opportunistic role of D. repens might explain the presence of asymptomatic carriers, the concurrent observation of nondermatological signs, and the development of dermatitis in a subgroup of parasitized dogs.

    Dengue fever is one of the world's most widely spread mosquito-borne diseases. International travelers who acquire dengue infection are important routes for virus transmission from one country to another one. Previous studies have shown that imported dengue cases are able to initiate indigenous epidemics when appropriate weather conditions are present. However, the spatial-temporal associations between imported cases and indigenous epidemics in areas with different social-economic conditions are still unclear. This study investigated determinants of spatial-temporal lags of imported dengue cases who initiated indigenous epidemics from 2003 to 2012 in Taiwan. The quantile regression is used to explore the associations between spatial-temporal lags of imported cases and social-economic indicators with geographic heterogeneity. Our results indicated that imported cases in April and May have statistically significant contribution to initiate indigenous epidemics. Areas with high population density and low average income have significant risk of being imported virus from other areas. However, the areas with imported cases are not significant transmission risk. The results imply that imported cases reported in early summer may be an early-warning indicator of indigenous epidemics. Local demographic and economic conditions, rather than imported cases, may determine the areas with the risk of indigenous epidemics.

    Vector symbolic architectures (VSAs) are high-dimensional vector representations of objects (e.g., words, image parts), relations (e.g., sentence structures), and sequences for use with machine learning algorithms. They consist of a vector addition operator for representing a collection of unordered objects, a binding operator for associating groups of objects, and a methodology for encoding complex structures. We first develop constraints that machine learning imposes on VSAs; for example, similar structures must be represented by similar vectors. The constraints suggest that current VSAs should represent phrases ("The smart Brazilian girl") by binding sums of terms, in addition to simply binding the terms directly. We show that matrix multiplication can be used as the binding operator for a VSA, and that matrix elements can be chosen at random. A consequence for living systems is that binding is mathematically possible without the need to specify, in advance, precise neuron-to-neuron connection properties for large numbers of synapses. A VSA that incorporates these ideas, Matrix Binding of Additive Terms (MBAT), is described that satisfies all constraints. With respect to machine learning, for some types of problems appropriate VSA representations permit us to prove learnability rather than relying on simulations. We also propose dividing machine (and neural) learning and representation into three stages, with differing roles for learning in each stage. For neural modeling, we give representational reasons for nervous systems to have many recurrent connections, as well as for the importance of phrases in language processing. Sizing simulations and analyses suggest that VSAs in general, and MBAT in particular, are ready for real-world applications. PMID:23607563

    Scientific knowledge and technological maturity are needed to establish regulatory requirements, what also needs talent and skills. Scientists are rarely interested in regulation and regulators not always are closely connected to scientific research. This has created gaps in regulations, mainly within qualified importers. A qualified importer, in the sense of this presentation, is a country who has acquired nuclear power plants from more technologically advanced exporters but with an increasing participation of its own industry and institutions in the design, construction, component manufacture and assembly of such nuclear power plants and is fully responsible for the operation of the nuclear units and the corresponding fuel cycle. These countries have also a long standing and independent nuclear regulatory organization and the corresponding technical body. Spain is a qualified importer. In the case of Spain, it originally adopted the codes and regulations of the UE which it was a member of, as well as the codes and standards of the country from which their reactors were produced. Since Spain added KWU plants they even went to German regulations. Plant operation rested with Spain. As problems began to appear in operating plants, local research projects were funded to study the problems, aimed at immediate solutions, but also providing training for local personnel in addition to information of use for regulators. Spain has participated in many joint research projects, which have trained people, and given confidence to Spaniards involved in science and regulations. Qualified importers, like Spain, participate in research, even though it may not translate itself into regulation. Such participation will always serve to give self-confidence and independence to regulators and licensees, to better understand the adopted regulations of the most advanced countries and to solve specific problems.

    Multiple myeloma (MM) is the second most common haematological malignancy in the UK. We present a case series of three patients with light chain only myeloma who had normal serum protein electrophoretic studies at screening and were diagnosed using serum and urine free light chain assessment. This series reiterates the importance of thorough and robust screening for MM in patients presenting with renal disease. We review the up to date literature and we highlight the need to screen patients for MM with a combination of serum electrophoresis/immunofixation and either urinary or serum free light chain measurement and to maintain a high index of suspicion regardless of the presence or absence of proteinuria. We also discuss the emerging role of the serum free light chain assay. PMID:25326567

    2014-01-01

    Objective: The aim of the present study was to consider the importance of medical information obtained via the Internet for difficult cases in hospitals, especially in those located in rural areas. We report here a case of congenital arteriovenous fistula (AVF) in the upper extremities. Patient: A 30-year-old lady was transported to our hospital by ambulance due to massive bleeding in her left hand. She was seen by our current cardiovascular surgery team for the first time, although she had been diagnosed with congenital AVF of the left arm 9 years previously. Because it was asymptomatic, she was followed up by observation. During 5 years of observation, symptoms such as cyanosis, pain, and refractory ulcers gradually developed. When she was 26 years old, she was referred to a university hospital in Akita, but surgery had already been judged to be impossible. When she was 30 years old, traumatic bleeding in her left hand and hemorrhagic shock led her to be taken to our hospital by ambulance. Using the Internet, we found an institution that had treated a large number of cases of AVF. After controlling the bleeding, we referred her to that institution. However, she could not be treated without an above-elbow amputation. Conclusion: Congenital AVF in the upper extremities is a rare vascular anomaly and has been generally accepted to be an extremely difficult disease to treat. Treatment should be started as early as possible before the presence of any symptoms. When a specialist is not available near the hospital, precise information must be found using the Internet and the patient should be referred without any delay. PMID:25650050

    According to Portuguese law, if a case of intimate partner violence is noticed or suspected by a professional working in public services, reporting it to the police, medico-legal services or directly to the public prosecutor is mandatory. However, in most cases, reporting does not take place, despite its vital importance in triggering the multidisciplinary intervention that will ensure the correct and timely diagnosis and protection of the victim. In the present case, the victim, a 37 year-old woman, was sexually and physically abused by her husband in their home, and was physically abused again at the victim's mother's house. The victim mentioned that her husband struck her in the head with a hammer and shot a handgun while in her mother's house. However, she denied having a gunshot wound. The couple's daughter was also slapped in the face by her father. The police took the victim to the emergency room of a central hospital to receive medical attention, while the medical examiner on duty was called to the same emergency room to perform a medico-legal evaluation in the context of the intimate partner violence reported to the police. Medico-legal assessment revealed scalp injuries that had not been detected during the first inspection by the emergency room attending physicians who had performed a neurological examination, which revealed no neurological dysfunction. A cranial computed tomography with three-dimensional reconstitution and virtual dissection, requested by the medical examiner, revealed two projectiles trapped in between the inner and the outer table of the cranium, with linear fractures only in the inner table and no brain injuries. Gynecological examination with the collection of biological evidence, also performed by the medical examiner, made it possible to identify a male DNA profile matching her husband's. The victim was subjected to neurosurgery and a follow-up, and was released one month after the traumatic event. A forensic psychological

    This paper illustrates the importance of monitoring health facility-level information to monitor changes in maternal mortality risks. The annual facility-level maternal mortality ratios (MMRs), complications to live births ratios and case fatality ratios (CFRs) were computed from data recorded during 2007 and 2009 in 31 upgraded public sector health facilities across Pakistan. The facility-level MMR declined by about 18%; both the number of Caesarean sections and the episodes of complications as a percentage of live births increased; and CFR based on Caesarean sections and episodes of complications declined by 29% and 37%, respectively. The observed increases in the proportion of women with complications among those who come to these facilities point to a reduction in the delay in reaching facilities (first and second delays; Thaddeus & Maine, 1994); the decrease in CFRs points to improvements in treating obstetric complications and a reduction in the delay in receiving treatment once at facilities (the third delay). These findings point to a decline in maternal mortality risks among communities served by these facilities. A system of woman-level data collection instituted at health facilities with comprehensive emergency obstetric care is essential to monitor changes in the effects of any reduction in the three delays and any improvement in quality of care or the effectiveness of treating pregnancy-related complications among women reaching these facilities. Such a system of information gathering at these health facilities would also help policymakers and programme mangers to measure and improve the effectiveness of safe-motherhood initiatives and to monitor progress being made toward achieving the fifth Millennium Development Goal.

  17. Do regional climate models represent regional climate?

    NASA Astrophysics Data System (ADS)

    Maraun, Douglas; Widmann, Martin

    2014-05-01

    When using climate change scenarios - either from global climate models or further downscaled - to assess localised real world impacts, one has to ensure that the local simulation indeed correctly represents the real world local climate. Representativeness has so far mainly been discussed as a scale issue: simulated meteorological variables in general represent grid box averages, whereas real weather is often expressed by means of point values. As a result, in particular simulated extreme values are not directly comparable with observed local extreme values. Here we argue that the issue of representativeness is more general. To illustrate this point, assume the following situations: first, the (GCM or RCM) simulated large scale weather, e.g., the mid-latitude storm track, might be systematically distorted compared to observed weather. If such a distortion at the synoptic scale is strong, the simulated local climate might be completely different from the observed. Second, the orography even of high resolution RCMs is only a coarse model of true orography. In particular in mountain ranges the simulated mesoscale flow might therefore considerably deviate from the observed flow, leading to systematically displaced local weather. In both cases, the simulated local climate does not represent observed local climate. Thus, representativeness also encompasses representing a particular location. We propose to measure this aspect of representativeness for RCMs driven with perfect boundary conditions as the correlation between observations and simulations at the inter-annual scale. In doing so, random variability generated by the RCMs is largely averaged out. As an example, we assess how well KNMIs RACMO2 RCM at 25km horizontal resolution represents winter precipitation in the gridded E-OBS data set over the European domain. At a chosen grid box, RCM precipitation might not be representative of observed precipitation, in particular in the rain shadow of major moutain ranges

    A critical role for regional climate models is downscaling coarse spatial resolution global model simulations of climate change to the much higher resolution required for assessment of regional changes and impacts. But what degree of downscaling is required? Fully coupled global climate models typically have resolutions of at best 100-200 km. The most recent set of IPCC reports suggest that the scale of regional/local impacts to climate change are on the order of 10 km. The scale mismatch is obvious, but less clear is what degree the climate simulations must be downscaled to meet the needs of impacts studies - other non-climate factors might also be crucial or even dominant. We have made a series of simulations with the WRF ARW for the U.S., large portions of Latin America, and South and Southeast Asia. Each set of runs includes a large outer domain at 48 km; an intermediate domain at 12 km (that is the primary basis for model results and interpretations); and one or more 'exploratory' inner domains at 4 km. The latter include regions with complex topography as well as both homogeneous and inhomogeneous land surface types. For each region a multi-year control forced by NCEP reanalyses has been made. Experiments for Asia are focusing on the effects of deforestation, while those for the U.S. and Latin America are focusing on IPCC climate change scenarios (A1FI for the U.S. and A2 for Latin America). Large-scale forcings for the latter two are provided by NCAR CCSM IPCC AR4 simulations. Preliminary results suggest that the higher resolutions have much more structure in standard climate quantities such as temperature or precipitation. Less obvious, however, is how realistic these structures are. In some cases, they clearly follow the better resolution of topography; in other instances the reason is less certain. Furthermore, observational datasets are frequently inadequate in assessing realism, especially for the non-U.S. domains. Finally, this work raises the issue of

    concentrations from the diffusion experiments represent true equilibrium solubilities. Another test of internal consistency is that the ratios of the interface concentrations between experiments buffered by Mg2SiO4 + Mg2Si2O6 + ZrSiO4 or Mg2SiO4 + ZrSiO4 + ZrO2 (high silica activity) to those buffered by Mg2SiO4 + MgO + ZrO2 (low silica activity) agree well with the ratios calculated from thermodynamic data. This study highlights the importance of buffering chemical potentials in diffusion experiments to provide constraints on the interface diffusant concentrations and hence validate the assumption of interface equilibrium.

  1. A spatial framework for representing nearshore ecosystems

    The shallow, coastal regions of the world's oceans are highly productive ecosystems providing important habitat for commercial, forage, endangered, and iconic species. Given the diversity of ecosystem services produced or supported by this ecosystem, a better understanding of its structure and function is central to developing an ecosystem-based approach to management. However this region - termed the ‘white strip' by marine geologists because of the general lack of high-resolution bathymetric data - is dynamic, highly variable, and difficult to access making data collection challenging and expensive. Since substrate is a key indicator of habitat in this important ecosystem, our objective was to create a continuous substrate map from the best available bottom type data. Such data are critical to assessments of species distributions and anthropogenic risk. Using the Strait of Georgia in coastal British Columbia, Canada, as a case study, we demonstrate how such a map can be created from a diversity of sources. Our approach is simple, quantitative, and transparent making it amenable to iterative improvement as data quality and availability improve. We evaluated the ecological performance of our bottom patches using observed shellfish distributions. We found that observations of geoduck clam, an infaunal species, and red urchins, a species preferentially associated with hard bottom, were strongly and significantly associated with our soft and hard patches respectively. Our description of bottom patches also corresponded well with a more traditional, morphological classification of a portion of the study area. To provide subsequent analyses (such as habitat models) with some confidence in the defined bottom type values, we developed a corresponding confidence surface based on the agreement of, and distance between observations. Our continuous map of nearshore bottom patches thus provides a spatial framework to which other types of data, both abiotic (e.g., energy) and

    Zoos present a unique assemblage of arthropods, captive vertebrates, free-roaming wildlife, humans, and plants, each with its own biota of symbiotic organisms. Arthropods of medicoveterinary importance are well represented in zoos, and an ample literature documents their influence in these animal-rich environments. Mosquitoes are of greatest significance because of the animal and human pathogens they transmit, followed by ectoparasites, many of which are exotic and present health risks to captive and native animals. Biting flies, cockroaches, filth flies, and triatomid bugs represent additional concerns. Integrated management programs for arthropods in zoos are commonplace. Zoos can play a role in biosurveillance, serving as an advanced guard for detecting exotic arthropods and vector-borne diseases. We provide the first review of arthropods of medicoveterinary importance in zoos. A case is made for the value of collaborations between entomologists and zoo personnel as a means of enhancing research and public education while safeguarding the health of captive animals and the public.

    Fever in a returned traveler from the tropics often poses a diagnostic challenge to the emergency department physician because of the potential for serious morbidity and mortality associated with certain infections such as falciparum malaria and dengue. We report a case of imported dengue fever in a 15-year-old adolescent boy acquired during a recent travel to Guatemala. Dengue fever is a mosquito-transmitted viral infection of global importance. The majority of US residents with dengue become infected during travel to tropical areas. In recent years, dengue has remerged in US tropical and subtropical areas. The disease is underreported in the United States along the Mexican border. The epidemiology, clinical manifestations, diagnosis, control, and prevention of this important global reemerging infectious disease are reviewed. Clinicians should include dengue in the differential diagnosis of febrile illness in children who have recently returned from dengue endemic areas.

    Introduction: Melorheostosis is a benign bone dysplasia affecting predominantly the appendicular skeleton and adjoining soft tissues. The diagnosis can be established on plain radiographs alone and advanced imaging modalities can be avoided. We hereby report a rare case of melorheostosis affecting the foot with a review of the role of various imaging modalities in diagnosis of this rare bone dysplasia. Case Report: We present the case of a 29 years old man who was diagnosed with melorheostosis affecting his left foot. The patient presented to the outpatient department of our tertiary care referral hospital with complains of pain in the left ankle and foot with imaging and evaluation done at a primary center. The radiograph revealed an irregular, longitudinal extraosseous hyperostosis along the body of the calcaneum and the metacarpals which was consistent with the classical radiological description of melorheostosis. The CT, MRI and bone scan findings corroborated our primary diagnosis. Conclusion: The purpose of this case report is to review the features of this rare disorder affecting the foot, on multiple imaging modalities and emphasizing the role of conventional radiology in its diagnosis.

    Resolutions were developed for each problem encountered and a tradeoff analysis was performed to select a final configuration for a flight representative PID (Positive Isolation Disconnect) that is reduced in size and comparable in weight and pressure drop to the developmental PID. A 6.35 mm (1/4-inch) line size PID was fabricated and tested. The flight representative PID consists of two coupled disconnect halves, each capable of fluid isolation with essentially zero clearance between them for zero leakage upon disconnect half disengagement. An interlocking foolproofing technique prevents uncoupling of disconnect halves prior to fluid isolation. Future development efforts for the Space Shuttle subsystems that would benefit from the use of the positive isolation disconnect are also recommended. Customary units were utilized for principal measurements and calculations with conversion factors being inserted in equations to convert the results to the international system of units.

    Synthetic Aperture Radar (SAR) images are often complex-valued to facilitate specific exploitation modes. Furthermore, these pixel values are typically represented with either real/imaginary (also known as I/Q) values, or as Magnitude/Phase values, with constituent components comprised of integers with limited number of bits. For clutter energy well below full-scale, Magnitude/Phase offers lower quantization noise than I/Q representation. Further improvement can be had with companding of the Magnitude value.

  11. Identifying representative trees from ensembles.

    Banerjee, Mousumi; Ding, Ying; Noone, Anne-Michelle

    2012-07-10

    Tree-based methods have become popular for analyzing complex data structures where the primary goal is risk stratification of patients. Ensemble techniques improve the accuracy in prediction and address the instability in a single tree by growing an ensemble of trees and aggregating. However, in the process, individual trees get lost. In this paper, we propose a methodology for identifying the most representative trees in an ensemble on the basis of several tree distance metrics. Although our focus is on binary outcomes, the methods are applicable to censored data as well. For any two trees, the distance metrics are chosen to (1) measure similarity of the covariates used to split the trees; (2) reflect similar clustering of patients in the terminal nodes of the trees; and (3) measure similarity in predictions from the two trees. Whereas the latter focuses on prediction, the first two metrics focus on the architectural similarity between two trees. The most representative trees in the ensemble are chosen on the basis of the average distance between a tree and all other trees in the ensemble. Out-of-bag estimate of error rate is obtained using neighborhoods of representative trees. Simulations and data examples show gains in predictive accuracy when averaging over such neighborhoods. We illustrate our methods using a dataset of kidney cancer treatment receipt (binary outcome) and a second dataset of breast cancer survival (censored outcome).

    T-cell prolymphocytic leukemia (T-PLL) is a rare form of leukemia composed of mature T-cells that usually presents in older people with a median age of 65. Most cases of T-PLL will harbor chromosomal abnormalities involving 14q11.2 (TCR alpha/delta), 14q32 (TCL1) or Xq28 (MTCP-1), abnormalities of chromosome 8, 12p and deletions of the long arm of chromosomes 5, 6, 11 and 13. Cytogenetics, FISH, comparative genomic hybridization (CGH) , SNP arrays with high resolution analysis have provided more precisely frequent submicroscopic gene and genomic lesions as well as breakpoints involved in the pathogenesis of this disease. One of the cornerstones to diagnose T-PLL are cytogenetic analysis. Here we summarize the current cytogenetic findings and we also describe two distinct cases of T-PLL where cytogenetics, FISH , morphologic analysis and flow cytometry helped to diagnose them accurately.

    Background Optimum efficiency of the folate pathway is considered essential for adequate ovarian function. 677 C>T substitution in the 5, 10-methylene tertrahydrofolatereductase (MTHFR) gene compromises activity of the MTHFR enzyme by about 50%. The significance of correlation between 677C>T substitution and PCOS remains dubious due to the low power of published studies. Methods and Results We analyzed MTHFR 677 C>T site in ethnically two different PCOS case-control groups (total 261 cases and 256 controls) from India. The data analysis revealed a lack of association between this polymorphism and PCOS [OR = 1.11 (95%CI = 0.71–1.72), P = 0.66]. Group-wise analysis on the basis of ethnicity also revealed no association in any of the ethnic groups [Indo-Europeans, P = 1; Dravidians, P = 0.70]. Homocysteine levels did not differ significantly between cases (15.51 μmol/L, SD = 2.89) and controls (15.89 μmol/L, SD = 2.23). We also undertook a meta-analysis on 960 cases and 1028 controls, which suggested a significant association of the substitution with PCOS in the dominant model of analysis (OR = 1.47 (95%CI = 1.04–2.09), P = 0.032]. Trial sequential analysis corroborated findings of the traditional meta-analysis. However, we found that the conclusions of meta-analysis were strongly influenced by studies that deviated from the Hardy Weinberg equilibrium. A careful investigation of each study and a trial sequential analysis suggested that 677 C>T substitution holds no clinical significance in PCOS in most of the populations. Conclusion In conclusion, MTHFR 677 C>T polymorphism does not affect PCOS risk in India. The association seen in the meta-analysis is due to an outlier study and studies showing deviation from the Hardy Weinberg equilibrium. PMID:26983014

    The Representative Shuttle Environmental Control System (RSECS) provides a ground test bed to be used in the early accumulation of component and system operating data, the evaluation of potential system improvements, and possibly the analysis of Shuttle Orbiter test and flight anomalies. Selected components are being subjected to long term tests to determine endurance and corrosion resistance capability prior to Orbiter vehicle experience. Component and system level tests in several cases are being used to support flight certification of Orbiter hardware. These activities are conducted as a development program to allow for timeliness, flexibility, and cost effectiveness not possible in a program burdened by flight documentation and monitoring constraints.

    The authors emphasize the importance of a complete examination, including history, symptomatology and instrumental tests in the diagnosis of osteoid osteoma (O.O.). This lesion is often difficult to diagnose, particularly at unusual sites. However, by the use of accurate radiography, stratigraphy, bone scan and CAT, a pre-operative accurate diagnosis is usually possible. The authors emphasize the importance of the least invasive surgical approach and the complete removal of the lesion with generous curettage. This is not always easy, as illustrated in the present study, which includes atypical sites, sometimes in delicate anatomical situations. They also illustrate a particular method used for removal.

    Deep convective thunderstorms affect the vertical distribution of chemical species through vertical transport, lightning-production of NOx, wet scavenging of soluble species as well as aqueous and ice chemistry. This work focuses on the May 29 Oklahoma thunderstorm from the DC3 (Deep Convective Clouds and Chemistry) field campaign. WRF-Chem simulations at cloud parameterizing scales (dx=15km) and cloud resolving scales (dx=3 and 1km) are conducted to investigate wet scavenging of soluble trace gases. Two different wet scavenging schemes are coupled to the Morrison microphysics scheme and MOZART chemistry. The first, based on Neu and Prather (ACP, 2012), tracks dissolved species in cloud droplets and precipitation and releases species to the gas phase from evaporating precipitation. However, it does not distinguish between precipitating liquid and ice, and species are completely retained upon hydrometeor freezing. The second, described in Barth et al. (JGR, 2001), tracks solute in individual liquid and frozen hydrometeors, and a new capability to specify the fraction of each species that is retained in ice upon hydrometeor freezing is added. The simulated meteorology, evaluated with the NEXRAD radar reflectivity, is shown to represent the structure and evolution of the storm, although the simulated storm triggers about an hour early, has a larger area of high reflectivity and extends further north than observed in NEXRAD. Vertical distributions of trace gases with varying solubilities within the storm and immediately surrounding the storm are compared with observations from the GV and DC-8 aircraft in storm inflow and outflow regions. Using the Neu and Prather scheme or using the Barth scheme with zero or complete ice retention, observed mean vertical profiles of some soluble species in outflow are better represented in the model with scavenging, while others are overly scavenged. Finally, sensitivity studies are conducted to determine ice retention factors for each

  18. Overview on relative importance of house dust ingestion in human exposure to polybrominated diphenyl ethers (PBDEs): International comparison and Korea as a case.

    Human exposure studies to polybrominated diphenyl ethers (PBDEs) have reached different results about the relative importance of diet intake and house dust ingestion. In the present study, concentrations of PBDEs in Korean house dust (n=15) from geographically different cities were measured, which were in agreement with a previous result, and compared with those for 22 countries of five continents collected from the most recent scientific literature. Compared with other exposure pathways, diet intake was the most important contributor to total PBDEs exposure of Korean adults (i.e., 71% of overall intake). On global comparison, total PBDE levels in house dust differed by two to three orders of magnitude among the countries investigated, with a significant relationship with gross domestic product (GDP). Whereas, dietary daily intakes exhibited a narrow difference within one order of magnitude worldwide and no relationship with GDP. Consequently, the relative importance of major two pathways depended on the contamination extent of PBDEs in house dust, which may be associated with the amount of PBDE products in use. In most countries except for UK and USA, the contribution of house dust ingestion was less important than diet intake in the current and are expected to much more mitigate in the future. However, how fast the effect of regulation will be reflected to house dust and human exposure is necessary to be monitored steadily.

  1. An economic approach to assessing import policies designed to prevent the arrival of invasive species: the case of Puccinia psidii in Hawai'i

    Since its first documented introduction to Hawai‘i in 2005, the rust fungus Puccinia psidii has already severely damaged Syzygium jambos (Indian rose apple) trees and the federally endangered Eugenia koolauensis (nioi). Fortunately, the particular strain has yet to cause serious damage to Metrosideros polymorpha (‘ōhi‘a), which comprises roughly 80% of the state's native forests and covers 400,000 ha. Although the rust has affected less than 5% of Hawaii's ‘ōhi‘a trees thus far, the introduction of more virulent strains and the genetic evolution of the current strain are still possible. Since the primary pathway of introduction is Myrtaceae plant material imported from outside the state, potential damage to ‘ōhi‘a can be minimized by regulating those high-risk imports. We discuss the economic impact on the state's florist, nursery, landscaping, and forest plantation industries of a proposed rule that would ban the import of non-seed Myrtaceae plant material and require a 1-year quarantine of seeds. Our analysis suggests that the benefits to the forest plantation industry of a complete ban on non-seed material would likely outweigh the costs to other affected sectors, even without considering the reduction in risk to ‘ōhi‘a. Incorporating the value of ‘ōhi‘a protection would further increase the benefit–cost ratio in favor of an import ban.

    Fish is an important source of protein all over the world, including in Ghana. The fishery sector plays a major role in meeting the domestic need of animal protein and also contributes greatly in foreign exchange earnings. The domestic supply of fish does not meet the demand, so Ghana imports fish and fish products from other countries. Media reports in Ghana have alleged the use of formaldehyde to preserve fish for increased shelf life and to maintain freshness. This research, therefore, sought to establish the levels of formaldehyde in imported and local fresh fish in the Tamale Metropolis by using a ChemSee formaldehyde and formalin detection test kit. Positive and negative controls were performed by using various concentrations of formalin (1, 10, 30, 50, 100, and 300 ppm) and sterile distilled water, respectively. Three times over a 6-month period, different fish species were obtained from five wholesale cold stores (where fish are sold in cartons) and some local sales points (where locally caught fish are sold). A total of 32 samples were taken during three different sampling sessions: 23 imported fish (mackerel, herring, horse mackerel, salmon, and redfish) and 9 local tilapia. The fish were cut, and 50 g was weighed and blended with an equal volume (50 ml) of sterile distilled water. Samples were transferred to test tubes and centrifuged. A test strip was dipped into the supernatant and observed for a color change. A change in color from white to pink or purple indicated the presence of formaldehyde in fish. The study showed that no formaldehyde was present in the imported and local fish obtained. The appropriate regulatory agencies should carry out this study regularly to ensure that fish consumed in Ghana is safe for consumption.

  7. What can we learn from the existing evidence of the business case for investments in nursing care: importance of content, context, and policy environment.

    2013-04-01

    Decisions of health care institutions to invest in nursing care are often guided by mixed and conflicting evidence of effects of the investments on organizational function and sustainability. This paper uses new evidence generated through Interdisciplinary Nursing Quality Research Initiative (INQRI)-funded research and published in peer-reviewed journals, to illustrate where the business case for nursing investments stands and to discuss factors that may limit the existing evidence and its transferability into clinical practice. We conclude that there are 3 limiting factors: (1) the existing business case for nursing investments is likely understated due to the inability of most studies to capture spillover and long-run dynamic effects, thus causing organizations to forfeit potentially viable nursing investments that may improve long-term financial stability; (2) studies rarely devote sufficient attention to describing the content and the organization-specific contextual factors, thus limiting generalizability; and (3) fragmentation of the current health care delivery and payment systems often leads to the financial benefits of investments in nursing care accruing outside of the organization incurring the costs, thus making potentially quality-improving and cost-saving interventions financially unattractive from the organization's perspective. The payment reform, with its emphasis on high-quality affordable patient-centered care, is likely to strengthen the business case for investments in nursing care. Methodologically rigorous approaches that focus on broader societal implications of investments in nursing care, combined with a thorough understanding of potential barriers and facilitators of nursing change, should be an integral part of future research and policy efforts.

  8. Representing culture in interstellar messages

    As scholars involved with the Search for Extraterrestrial Intelligence (SETI) have contemplated how we might portray humankind in any messages sent to civilizations beyond Earth, one of the challenges they face is adequately representing the diversity of human cultures. For example, in a 2003 workshop in Paris sponsored by the SETI Institute, the International Academy of Astronautics (IAA) SETI Permanent Study Group, the International Society for the Arts, Sciences and Technology (ISAST), and the John Templeton Foundation, a varied group of artists, scientists, and scholars from the humanities considered how to encode notions of altruism in interstellar messages . Though the group represented 10 countries, most were from Europe and North America, leading to the group's recommendation that subsequent discussions on the topic should include more globally representative perspectives. As a result, the IAA Study Group on Interstellar Message Construction and the SETI Institute sponsored a follow-up workshop in Santa Fe, New Mexico, USA in February 2005. The Santa Fe workshop brought together scholars from a range of disciplines including anthropology, archaeology, chemistry, communication science, philosophy, and psychology. Participants included scholars familiar with interstellar message design as well as specialists in cross-cultural research who had participated in the Symposium on Altruism in Cross-cultural Perspective, held just prior to the workshop during the annual conference of the Society for Cross-cultural Research . The workshop included discussion of how cultural understandings of altruism can complement and critique the more biologically based models of altruism proposed for interstellar messages at the 2003 Paris workshop. This paper, written by the chair of both the Paris and Santa Fe workshops, will explore the challenges of communicating concepts of altruism that draw on both biological

    Background. Fetal malformations and other structural abnormalities are relatively frequent findings in the course of routine prenatal ultrasonographic examination. Due to their considerable genetic and clinical heterogeneity, the underlying genetic cause is often elusive and the resulting inability to provide a precise diagnosis precludes proper reproductive and fetal risk assessment. We report the development and first applications of an expanded exome sequencing-based test, coupled to a bioinformatics-driven prioritization algorithm, targeting gene disorders presenting with abnormal prenatal ultrasound findings. Methods. We applied the testing strategy to14 euploid fetuses, from 11 on-going pregnancies and three products of abortion, all with various abnormalities or malformations detected through prenatal ultrasound examination. Whole exome sequencing (WES) was followed by variant prioritization, utilizing a custom analysis pipeline (Fetalis algorithm), targeting 758 genes associated with genetic disorders which may present with abnormal fetal ultrasound findings. Results. A definitive or highly-likely diagnosis was made in 6 of 14 cases (43%), of which 3 were abortuses (Ellis-van Creveld syndrome, Ehlers-Danlos syndrome and Nemaline myopathy 2) and 3 involved on-going pregnancies (Citrullinemia, Noonan syndrome, PROKR2-related Kallmann syndrome). In the remaining eight on-going pregnancy cases (57%), a ZIC1 variant of unknown clinical significance was detected in one case, while in seven cases testing did not reveal any pathogenic variant(s). Pregnancies were followed-up to birth, resulting in one neonate harboring the PROKR2 mutation, presenting with isolated minor structural cardiac abnormalities, and in seven apparently healthy neonates. Discussion. The expanded targeted exome sequencing-based approach described herein (Fetalis), provides strong evidence suggesting a definite and beneficial increase in our diagnostic capabilities in prenatal diagnosis of

    In May 2014, a traveler from the Kingdom of Saudi Arabia was the first person identified with Middle East respiratory syndrome coronavirus (MERS-CoV) infection in the United States. To evaluate transmission risk, we determined the type, duration, and frequency of patient contact among health care personnel (HCP), household, and community contacts by using standard questionnaires and, for HCP, global positioning system (GPS) tracer tag logs. Respiratory and serum samples from all contacts were tested for MERS-CoV. Of 61 identified contacts, 56 were interviewed. HCP exposures occurred most frequently in the emergency department (69%) and among nurses (47%); some HCP had contact with respiratory secretions. Household and community contacts had brief contact (e.g., hugging). All laboratory test results were negative for MERS-CoV. This contact investigation found no secondary cases, despite case-patient contact by 61 persons, and provides useful information about MERS-CoV transmission risk. Compared with GPS tracer tag recordings, self-reported contact may not be as accurate. PMID:26079176

    The present report details the case of a 13-year-old girl who presented to the emergency department with stridor. Treatment for presumed reactive airway disease was attempted with antibiotics, nebulized adrenaline masks and high-dose corticosteroids. Over the next month, she presented repeatedly in a similar fashion and was admitted to hospital on three separate occasions. Ultimately, she was referred to the Centre for Paediatric Voice and Laryngeal Function at The Hospital for Sick Children (Toronto, Ontario) for a speech-language pathology evaluation and direct laryngoscopy. The patient was diagnosed with paradoxical vocal fold dysfunction. After a brief treatment session with a speech-language pathologist, her stridor completely resolved and paradoxical inspiratory vocal fold adduction was no longer visualized on direct laryngoscopy. The present case highlights the fact that paradoxical vocal fold dysfunction can mimic other entities that present with stridor, and misdiagnosis can result in significant morbidity. Investigation into a patient’s social history and stressors can facilitate the diagnosis, and can avoid unnecessary and potentially harmful medical and surgical interventions. PMID:19436501

    Families affected by Paget's disease of bone frequently harbor mutations in the SQSTM1/p62 gene. In this multicentric study we collected 345 sporadic and 12 familial PDB cases throughout Italy, identifying 12 different mutations, 5 of which are newly reported and 3, D335E, A381V, and Y383X, external to the UBA domain. Subjects with truncating mutations, E396X, showed a significantly younger age at clinical diagnosis, while the Y383X subjects had a higher average number of affected skeletal sites. All the mutants exhibited the CGTG-H2 haplotype. In two pairs and one triad of unrelated Italian PDB families from different Italian regions, we detected a common SQSTM1/p62 mutation for each P392L, M404V, and G425R group. Since the CGTG-H2 haplotype frequency was also high in normal subjects, and genetic influence due to migratory fluxes of different ethnic groups exists in the Italian population, to refine the search for a more geographically specific founder effect, we extended the haplotype analysis in these families using polymorphic microsatellite repeat markers, within and flanking the SQSTM1/p62 locus, from chromosome 5q35, other than the exon 6 and 3'UTR polymorphisms. All mutant carriers from two of the three M404V families and from the G425R families exhibited common extended chromosome 5q35 haplotypes, IT01 and IT02, respectively, which may be reflecting influences of past migrations. This may be helpful in estimating the true rate of de novo mutations. We confirm the data on the existence of both a mutational hotspot at the UBA domain of SQSTM1/p62 and a founder effect in the PDB population.

    Zoonoses are an important class of infectious diseases. An important element determining the impact of a zoonosis on domestic animal and human health is host range. Although for particular zoonoses some host species have been identified, until recently there have been no methods to predict those species most likely to be hosts or their relative importance. Complex inference networks infer potential biotic interactions between species using their degree of geographic co-occurrence, and have been posited as a potential tool for predicting disease hosts. Here we present the results of an interdisciplinary, empirical study to validate a model based on such networks for predicting hosts of Leishmania (L.) mexicana in Mexico. Using systematic sampling to validate the model predictions we identified 22 new species of host (34% of all species collected) with the probability to be a host strongly dependent on the probability of co-occurrence of vector and host. The results confirm that Leishmania (L.) mexicana is a generalist parasite but with a much wider host range than was previously thought. These results substantially change the geographic risk profile for Leishmaniasis and provide insights for the design of more efficient surveillance measures and a better understanding of potential dispersal scenarios.

    ABSTRACT The Middle East respiratory syndrome coronavirus (MERS-CoV) causes a severe acute respiratory tract infection with a high fatality rate in humans. Coronaviruses are capable of infecting multiple species and can evolve rapidly through recombination events. Here, we report the complete genomic sequence analysis of a MERS-CoV strain imported to China from South Korea. The imported virus, provisionally named ChinaGD01, belongs to group 3 in clade B in the whole-genome phylogenetic tree and also has a similar tree topology structure in the open reading frame 1a and -b (ORF1ab) gene segment but clusters with group 5 of clade B in the tree constructed using the S gene. Genetic recombination analysis and lineage-specific single-nucleotide polymorphism (SNP) comparison suggest that the imported virus is a recombinant comprising group 3 and group 5 elements. The time-resolved phylogenetic estimation indicates that the recombination event likely occurred in the second half of 2014. Genetic recombination events between group 3 and group 5 of clade B may have implications for the transmissibility of the virus. PMID:26350969

    The European Geosciences Union is a bottom-up-organisation, in which its members are represented by their respective scientific divisions, committees and council. In recent years, EGU has embarked on a mission to reach out for its numerous 'younger' members by giving awards to outstanding young scientists and the setting up of Early Career Scientists (ECS) representatives. The division representative's role is to engage in discussions that concern students and early career scientists. Several meetings between all the division representatives are held throughout the year to discuss ideas and Union-wide issues. One important impact ECS representatives have had on EGU is the increased number of short courses and workshops run by ECS during the annual General Assembly. Another important contribution of ECS representatives was redefining 'Young Scientist' to 'Early Career Scientist', which avoids discrimination due to age. Since 2014, the Seismology Division has its own ECS representative. In an effort to more effectively reach out for young seismologists, a blog and a social media page dedicated to seismology have been set up online. With this dedicated blog, we'd like to give more depth to the average browsing experience by enabling young researchers to explore various seismology topics in one place while making the field more exciting and accessible to the broader community. These pages are used to promote the latest research especially of young seismologists and to share interesting seismo-news. Over the months the pages proved to be popular, with hundreds of views every week and an increased number of followers. An online survey was conducted to learn more about the activities and needs of early career seismologists. We present the results from this survey, and the work that has been carried out over the last two years, including detail of what has been achieved so far, and what we would like the ECS representation for Seismology to achieve.

    Water is the most abundant compound in interstellar and cometary ices. Laboratory experiments on ice analogues have shown that water has a great influence on the chemical activity of these ices. In this study, we investigated the reactivity of acetone-ammonia ices, showing that water is an essential component in chemical reactions with high activation energies. In a water-free binary ice, acetone and ammonia do not react due to high activation energy, as the reactants desorb before reacting (at 120 and 140 K, respectively). By contrast, our study shows that under experimental conditions of ˜150 K, this reaction does occur in the presence of water. Here, water traps reactants in the solid phase above their desorption temperatures, allowing them to gather thermal energy as the reaction proceeds. Using infrared spectroscopy and mass spectrometry associated with isotopic labelling, as well as quantum chemical calculations, 2-aminopropan-2-ol (2HN-C(CH3)2-OH) was identified as the acetone-ammonia reaction product. The formation of this product may represent the first step towards formation of 2-aminoisobutyric acid (AIB) in the Strecker synthesis. The activation energy for the formation of 2-aminopropan-2-ol was measured to be 42 ± 3 kJ mol-1, while its desorption energy equalled 61.3 ± 0.1 kJ mol-1. Our work demonstrates that astrophysical water, rather than being a non-thermally reactive species, is crucial for the evolution of complex chemistry occurring in the Universe.

    The city of Querétaro, located near the political boundary of the Mexican states of Querétaro and Guanajuato, relies on groundwater as it sole water supply. Groundwater extraction in the city increased from 21 × 106 m3/yr in 1970 to 104 × 106 m3/yr in 2010, with an associated drawdown of 100 m in some parts of the aquifer. A three-dimensional numerical groundwater-flow model has been developed that represents the historical evolution of the aquifer's potentiometric levels and is used to simulate the effect of two scenarios: (1) a 40 % reduction in the extraction rate from public water supply wells in early 2011 (thus reducing the extraction to 62 × 106 m3/yr), and (2) a further reduction in 2021 to 1 × 106 m3/yr. The modeling results project a temporary recovery of the potentiometric levels after the 40 % reduction of early 2011, but a return to 2010 levels by 2020. If scenario 2 is implemented in 2021, the aquifer will take nearly 30 years to recover to the simulated levels of 1995. The model also shows that the wells located in the city of Querétaro started to extract water from part of the aquifer beneath the State of Guanajuato in the late 1970s, thus showing that the administrative boundaries used in Mexico to study and develop water resources are inappropriate, and consideration should be given to physical boundaries instead. A regional approach to studying aquifers is needed in order to adequately understand groundwater flow dynamics.

    Clozapine is the treatment of choice in refractory schizophrenia. Its more extensive use is limited by adverse effects and the need for regular blood monitoring. However, black patients are disadvantaged with respect to clozapine usage. Lower baseline Absolute Neutrophil Count compared with Whites leads to a greater frequency of blood testing, treatment interruptions and discontinuation. This may in part be explained by Benign Ethnic Neutropenia, but too few black patients are thus registered. The four cases described in this report underline some of the difficulties if this problem is under-recognized. Moreover, in our sample of 191 clozapine recipients in an inner London hospital, black patients account for approximately half, but only a small proportion, 8/95 (8.4%) are registered as having Benign Ethnic Neutropenia. None of the Benign Ethnic Neutropenia-registered patients discontinued treatment for haematological reasons. To optimize clozapine treatment and improve long-term outcomes, a significantly greater proportion of Black patients should be registered as having Benign Ethnic Neutropenia.

    Community case management (CCM) is a promising task-shifting strategy for expanding treatment of childhood illness that is increasingly adopted by low-income countries. Its success depends in part on how the strategy is perceived by those responsible for its implementation. This study uses qualitative methods to explore health workers' and managers' perceptions about CCM provided by health surveillance assistants (HSAs) during the program's first year in Malawi. Managers and HSAs agreed that CCM contributed beneficially by expanding access to the underserved and reducing caseloads at health facilities. Managers differed among themselves in their endorsements of CCM, most offered constrained endorsement, and a few had stronger justifications for CCM. In addition, HSAs uniformly wanted continued expansion of their clinical role, while managers preferred to view CCM as a limited mandate. The HSAs also reported motivating factors and frustrations related to system constraints and community pressures related to CCM. The impact of CCM on motivation and workload of HSAs is noted and deserves further attention.

    Weighting values for different habitat variables used in multi-factor habitat suitability index (HSI) modeling reflect the relative influences of different variables on distribution of fish species. Using the winter-spring cohort of neon flying squid ( Ommastrephes bartramii) in the Northwestern Pacific Ocean as an example, we evaluated the impact of different weighting schemes on the HSI models based on sea surface temperature, gradient of sea surface temperature and sea surface height. We compared differences in predicted fishing effort and HSI values resulting from different weighting. The weighting for different habitat variables could greatly influence HSI modeling and should be carefully done based on their relative importance in influencing the resource spatial distribution. Weighting in a multi-factor HSI model should be further studied and optimization methods should be developed to improve forecasting squid spatial distributions.

    In spring 2013, 5-year-old nectarine (Prunus persica) trees, grafted on peach rootstock Nemaguard, were found stunted in a propagation block in California. These trees had been propagated from budwood of three nectarine cultivars imported from France and cleared through the post-entry quarantine procedure. Examination of the canopy failed to reveal any obvious symptoms. However, examination of the trunks, after stripping the bark, revealed extensive pitting on the woody cylinder. To investigate the etiological agent, double-stranded RNA was extracted from bark scrapings from the scion and rootstock portions, and a cDNA library was prepared and sequenced using the Illumina platform. BLAST analysis of the contigs generated by the de novo assembly of sequence reads indicated the presence of a novel luteovirus. Complete sequence of the viral genome was determined by sequencing of three overlapping cDNA clones generated by reverse transcription-polymerase chain reaction (RT-PCR) and by rapid amplification of the 5'- and 3'-termini. The virus genome was comprised of 4,991 nucleotides with a gene organization similar to members of the genus Luteovirus (family Luteoviridae). The presence of the virus, tentatively named Nectarine stem pitting-associated virus, was confirmed in symptomatic trees by RT-PCR. Discovery of a new virus in nectarine trees after post-entry quarantine indicates the importance of including (i) metagenomic analysis by next-generation sequencing approach as an essential tool to assess the plant health status, and (ii) examination of the woody cylinders as part of the indexing process.

    Production and use of perfluorooctane sulfonate (PFOS) is regulated worldwide. However, numerous potential precursors that eventually decompose into PFOS and other perfluoroalkyl acids (PFAAs) such as perfluorooctanoic acid (PFOA) are still being used and have not been studied in detail. Therefore, knowledge about the levels and sources of the precursors is essential. We investigated the total concentration of potential PFAA precursors in the Tama River, which is one of the major rivers flowing into the Tokyo Bay, by converting all the perfluorinated carboxylic acid (PFCA) and perfluoroalkyl sulfonic acid (PFSA) precursors into PFCAs by chemical oxidation. The importance of controlling PFAA precursors was determined by calculating the ratios of PFCAs formed by oxidation to the PFAAs originally present (ΣΔ[PFCAC4-C12]/Σ[PFAAs]before oxidation) (average = 0.28 and 0.69 for main and tributary branch rivers, respectively). Higher total concentrations of Δ[PFCAs] were found in sewage treatment plant (STP) effluents. However, the ratios found in the effluents were lower (average = 0.21) than those found in the river water samples, which implies the decomposition of some precursors into PFAAs during the treatment process. On the other hand, higher ratios were observed in the upstream water samples and the existence of emission sources other than the STP effluents was indicated. This study showed that although the treatment process converting a part of the PFAA precursors into PFAAs, STPs were important sources of precursors to the Tama River. To reduce the levels of PFAAs in the aquatic environment, it is necessary to reduce the emission of the PFAA precursors as well.

  7. The underground electromagnetic pulse: Four representative models

    Wouters, L.F.

    I describe four phenomenological models by which an underground nuclear explosion may generate electromagnetic pulses: Compton current asymmetry (or ''Compton dipole''); Uphole conductor currents (or ''casing currents''); Diamagnetic cavity plasma (or ''magnetic bubble''); and Large-scale ground motion (or ''magneto-acoustic wave''). I outline the corresponding analytic exercises and summarize the principal results of the computations. I used a 10-kt contained explosion as the fiducial case. Each analytic sequence developed an equivalent source dipole and calculated signal waveforms at representative ground-surface locations. As a comparative summary, the Compton dipole generates a peak source current moment of about 12,000 A/center dot/m in the submicrosecond time domain. The casing-current source model obtains an equivalent peak moment of about 2 /times/ 10/sup 5/ A/center dot/m in the 10- to 30-/mu/s domain. The magnetic bubble produces a magnetic dipole moment of about 7 /times/ 10/sup 6/ A/center dot/m/sup 2/, characterized by a 30-ms time structure. Finally, the magneto-acoustic wave corresponds to a magnetic dipole moment of about 600 A/center dot/m/sup 2/, with a waveform showing 0.5-s periodicities. 8 refs., 35 figs., 7 tabs.

    A pilot expanded newborn screening programme to detect inherited metabolic disorders by means of liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) began in the Campania region, southern Italy, in 2007. By October 2009, >8,800 dried blood samples on filter paper from 11 hospitals had been screened. Within this screening programme, we identified a case of mitochondrial acetoacetyl-coenzyme A (CoA) thiolase deficiency [β-ketothiolase (β-KT) deficiency] by analysing the acylcarnitine profile from a dried blood spot with LC-MS/MS. Gas chromatography coupled with mass spectrometry analysis of urinary organic acids and LC-MS/MS analysis of urinary acylcarnitines were in line with this disorder. In fact, concentrations were well beyond the cut-off values of tiglyl carnitine, 3-hydroxybutyrylcarnitine and 2-methyl-3-hydroxybutyrylcarnitine, 2-methyl-3-hydroxybutyric acid and tiglyl glycine. The absence of 2-methylacetoacetic acid in urine may be attributed to: (i) the instability of this β-ketoacid because it undergoes spontaneous decarboxylation to 2-butanone, which is highly volatile and thus difficult to detect, and (ii) the good health of the patient in the first days of life. β-KT deficiency was subsequently diagnosed in the patient's older sister, who showed increased levels of the same metabolites but also small amounts of 2-methylacetoacetic acid, which is considered a key marker for β-KT diagnosis. Genomic analysis revealed mutation c.1189C >G in exon 12 of the ACAT1 gene, which results in a severe defect because of the p.H397D amino acid change in both alleles of both patients.

  9. Projectile penetration into representative targets

    Stone, George W.

    1994-10-01

    The differential equation representing the penetration of a 'hard' projectile into semi-infinite, homogeneous target materials is solved for several generic combinations of the target material/projectile characteristics. A 'hard' projectile is defined as one that does not change size or shape and does not lose mass during the penetration process. The target materials evaluated range from the structurally 'soft' materials (liquids) to structurally 'hard' materials (armor plate) with viscous and fluid dynamic drag considered. The solutions to the differential equation(s) are expanded in series form to demonstrate the underlying parameters governing projectile penetration and the way they interact to limit penetration in a given target material. It is shown that the fundamental parameter governing projectile penetration into structurally 'firm' materials is the initial kinetic energy of the projectile divided by the frontal area of the projectile and the inherent structural characteristic of the target. Experimental data on the penetration of steel spheres into ballistic gelatin and for armor piercing bullets into armor plate materials are used to verify the characteristics of the solutions to the equation of motion for the projectile and to demonstrate how penetration can vary with projectile size and target characteristics. The penetration equation for a single 'hard' target material is used to develop a solution for the penetration of multilayered 'hard' target materials.

Much of my work on the committee is related to fish, wildlife, oceans, lands, and water issues and is directly related to my background in ecology and evolutionary biology (I studied zebra ecology and behavior in Kenya). My assignments have included asking the Environmental Protection Agency (EPA) about why it has not changed the allowed usage of certain pesticides that the National Marine Fisheries Service has found to jeopardize the recovery of endangered Pacific salmon; helping to identify research needs and management options to combat the swiftly spreading and catastrophic white nose syndrome in North American bats; and inquiring as to whether a captive-ape welfare bill, if passed without amendment, could thwart development of a vaccine to stop the Ebola virus from continuing to cause mass mortality in endangered wild apes.

    More than 70% of reported human Salmonella infections in Norway are infected abroad. The Canary Islands and Thailand are two of the most popular charter tourist destinations for Norwegians. Using surveillance data for the years 1994-2008, and denominator data on travel to the Canary Islands 2000-2008 and to Thailand 1997-2008, we present the epidemiology and trends of Salmonella infections in Norwegian tourists to these destinations. We found a declining trend in risk of salmonellosis in tourists returning from the Canary Islands, and a change in serovar distribution in travellers to Thailand with more S. Enteritidis infections, similar to that observed in Western European countries. The use of denominator data is important when studying risk of travel-related disease, as surveillance data tend to reflect travel activity more than the risk. Infections among tourists do not always affect the local residents and therefore may not be detected by local public health authorities. Sharing knowledge on the epidemiology of infections in tourists could be useful for observation of changes in trends in the countries visited, and in future outbreak investigations. PMID:22051449

    This study considers an evaporating horizontal binary-liquid layer (aqueous solution of ethanol; mass fraction 0.1) in contact with air with an imposed transfer distance. Fully transient and horizontally homogeneous solutions for the reference state are first calculated. Then, the linear stability of these solutions is studied using the frozen-time approach. Solutal and thermal Rayleigh-Bénard-Marangoni instabilities are taken into account together with the Soret effect, although the solutal Marangoni mechanism appeared to be the most important one. Considering several gas-to-liquid thickness ratios (H) , we calculate the critical times for the instability onset in a liquid layer of a given thickness. We also uncover the minimum liquid thicknesses under which no instability can ever occur. We subsequently observe that two distinctly different types of minimum thicknesses exist depending on H, examining each one of them. Then a closed-form analysis of the instability at small times has been developed. Finally, it has also been observed that, regardless of the gas-to-liquid thickness ratio, an asymptotic value of the critical time exists as the liquid layer increases, this critical time being approximately 1 μs.

    Reproduction is a crucial stage in the naturalisation of introduced plant species. Here, using breeding system experiments and observations of floral visitors, we investigate whether a lack of pollinators or an inability to autonomously self-fertilise limits naturalisation in five Australian Banksia species and the co-familial Hakea salicifolia in South Africa. Banksia species were heavily utilised by native insects and nectar-feeding birds. Although Banksia produced fruit when pollinators were excluded, pollinators significantly increased seed set in four of the five species. H. salicifolia flowers were visited by 11 insect species; honeybees (Apis mellifera) were the main visitors. Flowers in naturalised H. salicifolia populations received almost four times the number of visits as flowers in non-naturalised populations; the latter showed both pollen limitation (PLI 0.40) and partial self-incompatibility. This should not prevent invasion, since H. salicifolia produces fruits via autonomous selfing in the absence of pollinators. The results suggest a limited role of breeding systems in mediating naturalisation of introduced Proteaceae species. Other factors, such as features of the recipient environments, appear to be more important. Spatial variation in rates of reproduction might, however, explain variation in the extent and rate of naturalisation of different populations.

    Environmental factors can play important roles in influencing waterbird communities. In particular, weather may have various biological and ecological impacts on the breeding activities of waterbirds, though most studies have investigated the effect of weather on the late stages of waterbird breeding (e.g., hatching rate, chick mortality). Conversely, the present study attempts to highlight the influence of weather on the early nesting activities of waterbirds by evaluating a recently established mixed-species colony in Putrajaya Wetlands, Malaysia. The results show that only rainfall and temperature have a significant influence on the species' nesting activities. Rainfall activity is significantly correlated with the Grey Heron's rate of establishment (rainfall: rs = 0.558, p = 0.03, n = 72) whereas both temperature and rainfall are associated with Painted Stork's nesting density (temperature: rs = 0.573, p = 0.013; rainfall: rs = -0.662, p = 0.03, n = 48). There is a possibility that variations in the rainfall and temperature provide a cue for the birds to initiate their nesting. Regardless, this paper addresses concerns on the limitations faced in the study and suggests long-term studies for confirmation.

    Pharmaceuticals are emerging contaminants of increasing concern because of their presence in the aquatic environment and potential to reach drinking-water sources. After human and/or veterinary consumption, pharmaceuticals can be excreted in unchanged form, as the parent compound, and/or as free or conjugated metabolites. Determination of most pharmaceuticals and metabolites in the environment is commonly made by liquid chromatography (LC) coupled to mass spectrometry (MS). LC coupled to tandem MS is the technique of choice nowadays in this field. The acquisition of two selected reaction monitoring (SRM) transitions together with the retention time is the most widely accepted criterion for a safe quantification and confirmation assay. However, scarce attention is normally paid to the selectivity of the selected transitions as well as to the chromatographic separation. In this work, the importance of full spectrum acquisition high-resolution MS data using a hybrid quadrupole time-of-flight analyser and/or a suitable chromatographic separation (to reduce the possibility of co-eluting interferences) is highlighted when investigating pharmaceutical metabolites that share common fragment ions. For this purpose, the analytical challenge associated to the determination of metabolites of the widely used analgesic dipyrone (also known as metamizol) in urban wastewater is discussed. Examples are given on the possibilities of reporting false positives of dypirone metabolites by LC-MS/MS under SRM mode due to a wrong assignment of identity of the compounds detected. PMID:22899513

    Abstract In this study, we analyse the relevance of harvestmen distribution data derived from opportunistic, unplanned, and non-standardised collection events in an area in the north of the Iberian Peninsula. Using specimens deposited in the BOS Arthropod Collection at the University of Oviedo, we compared these data with data from planned, standardised, and periodic collections with pitfall traps in several locations in the same area. The Arthropod Collection, begun in 1977, includes specimens derived from both sampling types, and its recent digitisation allows for this type of comparative analysis. Therefore, this is the first data-paper employing a hybrid approach, wherein subset metadata are described alongside a comparative analysis. The full dataset can be accessed through Spanish GBIF IPT at http://www.gbif.es:8080/ipt/archive.do?r=Bos-Opi, and the metadata of the unplanned collection events at http://www.gbif.es:8080/ipt/resource.do?r=bos-opi_unplanned_collection_events. We have mapped the data on the 18 harvestmen species included in the unplanned collections and provided records for some species in six provinces for the first time. We have also provided the locations of Phalangium opilio in eight provinces without published records. These results highlight the importance of digitising data from unplanned biodiversity collections, as well as those derived from planned collections, especially in scarcely studied groups and areas.

    2014-01-01

    Rapid changes in human behavior, resource utilization, and other extrinsic environmental factors continue to threaten the current distribution of several endemic and historically neglected zoonoses in many developing regions worldwide. There are numerous examples of zoonotic diseases which have circulated within relatively localized geographical areas for some time, before emerging into new regions as a result of changing human, environmental, or behavioral dynamics. While the world’s focus is currently on the Ebola virus gaining momentum in western Africa, another pertinent example of this phenomenon is zoonotic human African trypanosomiasis (HAT), endemic to south and eastern Africa, and spread via infected cattle. In recent years, the ongoing northwards spread of this disease in the country has posed a serious public health threat to the human population of Uganda, increasing the pressure on both individual families and government services to control the disease. Moreover, the emergence of HAT into new areas of Uganda in recent years exemplifies the important role of veterinary policy in mitigating the severe human health and economic impacts of zoonotic disease. The systemic challenges surrounding the development and enforcement of veterinary policy described here are similar across sub-Saharan Africa, highlighting the necessity to consider and support zoonotic disease control in broader human and animal health systems strengthening and associated development programs on the continent.

    Reproduction is a crucial stage in the naturalisation of introduced plant species. Here, using breeding system experiments and observations of floral visitors, we investigate whether a lack of pollinators or an inability to autonomously self-fertilise limits naturalisation in five Australian Banksia species and the co-familial Hakea salicifolia in South Africa. Banksia species were heavily utilised by native insects and nectar-feeding birds. Although Banksia produced fruit when pollinators were excluded, pollinators significantly increased seed set in four of the five species. H. salicifolia flowers were visited by 11 insect species; honeybees (Apis mellifera) were the main visitors. Flowers in naturalised H. salicifolia populations received almost four times the number of visits as flowers in non-naturalised populations; the latter showed both pollen limitation (PLI 0.40) and partial self-incompatibility. This should not prevent invasion, since H. salicifolia produces fruits via autonomous selfing in the absence of pollinators. The results suggest a limited role of breeding systems in mediating naturalisation of introduced Proteaceae species. Other factors, such as features of the recipient environments, appear to be more important. Spatial variation in rates of reproduction might, however, explain variation in the extent and rate of naturalisation of different populations. PMID:25865269

  1. Obtaining optical properties using Representative Layer Theory

    Reliable and minimally invasive methods for diagnosis of toxicity and onset of disease are important for advances in clinical practices. This is commonly achieved through the optical properties, such as a change in the absorption or scattering strength of the diseased tissue. Thus, being able to quantitatively characterize these changes is important to advancements in medical diagnostic methods. By adapting the Representative Layer Theory to the integrating sphere technique, very thin biological samples may be optically characterized, yielding a quick and easy method for monitoring optical changes as a function of disease progression. Samples, consisting of cells, dyes, and nanoparticles of known concentrations were optically characterized at multiple wavelengths. Optical properties obtained by the Representative Layer Theory are compared to those obtained through other methods, such as Kubelka-Munk and Inverse Adding Doubling which are known to have sample thickness limitations.

  2. Importance of plasticity and local adaptation for coping with changing salinity in coastal areas: a test case with barnacles in the Baltic Sea

    PubMed Central

    2014-01-01

    Background Salinity plays an important role in shaping coastal marine communities. Near-future climate predictions indicate that salinity will decrease in many shallow coastal areas due to increased precipitation; however, few studies have addressed this issue. The ability of ecosystems to cope with future changes will depend on species’ capacities to acclimatise or adapt to new environmental conditions. Here, we investigated the effects of a strong salinity gradient (the Baltic Sea system – Baltic, Kattegat, Skagerrak) on plasticity and adaptations in the euryhaline barnacle Balanus improvisus. We used a common-garden approach, where multiple batches of newly settled barnacles from each of three different geographical areas along the Skagerrak-Baltic salinity gradient were exposed to corresponding native salinities (6, 15 and 30 PSU), and phenotypic traits including mortality, growth, shell strength, condition index and reproductive maturity were recorded. Results We found that B. improvisus was highly euryhaline, but had highest growth and reproductive maturity at intermediate salinities. We also found that low salinity had negative effects on other fitness-related traits including initial growth and shell strength, although mortality was also lowest in low salinity. Overall, differences between populations in most measured traits were weak, indicating little local adaptation to salinity. Nonetheless, we observed some population-specific responses – notably that populations from high salinity grew stronger shells in their native salinity compared to the other populations, possibly indicating adaptation to differences in local predation pressure. Conclusions Our study shows that B. improvisus is an example of a true brackish-water species, and that plastic responses are more likely than evolutionary tracking in coping with future changes in coastal salinity.

    In a previous study on Zygosaccharomyces bailii, three growth/no growth models have been developed, predicting growth probability of the yeast at different conditions typical for acidified foods (Dang, T.D.T., Mertens, L., Vermeulen, A., Geeraerd, A.H., Van Impe, J.F., Debevere, J., Devlieghere, F., 2010. Modeling the growth/no growth boundary of Z. bailii in acidic conditions: A contribution to the alternative method to preserve foods without using chemical preservatives. International Journal of Food Microbiology 137, 1-12). In these broth-based models, the variables were pH, water activity and acetic acid, with acetic acid concentration expressed in volume % on the total culture medium (i.e., broth). To continue the previous study, validation experiments were performed for 15 selected combinations of intrinsic factors to assess the performance of the model at 22°C (60days) in a real food product (ketchup). Although the majority of experimental results were consistent, some remarkable deviations between prediction and validation were observed, e.g., Z. bailii growth occurred in conditions where almost no growth had been predicted. A thorough investigation revealed that the difference between two ways of expressing acetic acid concentration (i.e., on broth basis and on water basis) is rather significant, particularly for media containing high amounts of dry matter. Consequently, the use of broth-based concentrations in the models was not appropriate. Three models with acetic acid concentration expressed on water basis were established and it was observed that predictions by these models well matched the validation results; therefore a "systematic error" in broth-based models was recognized. In practice, quantities of antimicrobial agents are often calculated based on the water content of food products. Hence, to assure reliable predictions and facilitate the application of models (developed from lab media with high dry matter contents), it is important to express

    Path integral (PI) control problems are a restricted class of non-linear control problems that can be solved formally as a Feynman-Kac PI and can be estimated using Monte Carlo sampling. In this contribution we review PI control theory in the finite horizon case. We subsequently focus on the problem how to compute and represent control solutions. We review the most commonly used methods in robotics and control. Within the PI theory, the question of how to compute becomes the question of importance sampling. Efficient importance samplers are state feedback controllers and the use of these requires an efficient representation. Learning and representing effective state-feedback controllers for non-linear stochastic control problems is a very challenging, and largely unsolved, problem. We show how to learn and represent such controllers using ideas from the cross entropy method. We derive a gradient descent method that allows to learn feed-back controllers using an arbitrary parametrisation. We refer to this method as the path integral cross entropy method or PICE. We illustrate this method for some simple examples. The PI control methods can be used to estimate the posterior distribution in latent state models. In neuroscience these problems arise when estimating connectivity from neural recording data using EM. We demonstrate the PI control method as an accurate alternative to particle filtering.

    In what follows, we develop a conceptual argument for expanding current visions of performance assessment to include the following three ideals: that performance/assessment addresses the value-laden decisions about what and whose science is learned and assessed and include multiple worldviews, that performance/assessment in science simultaneously emerges in response to local needs, and that the performance/assessment is a method as well as an ongoing search for method. To make this argument, we draw together ideas raised by critical, feminist and multicultural science educators to describe an inclusive science education, one we refer to as critical science education, to raise questions about the nature and purpose of performance assessment in science education. We are particularly interested in how the science of assessment is challenged and transformed within a critical science education perspective and the conditions needed to create an equitable and inclusive practice of science and science assessment across diversity. We present a case study from a youth-led community science project in the inner city to help contextualize our argument.

  8. Swift J1644+57 gone MAD: the case for dynamically important magnetic flux threading the black hole in a jetted tidal disruption event

    The unusual transient Swift J1644+57 likely resulted from a collimated relativistic jet, powered by the sudden onset of accretion on to a massive black hole (BH) following the tidal disruption (TD) of a star. However, several mysteries cloud the interpretation of this event, including (1) the extreme flaring and `plateau' shape of the X-ray/γ-ray light curve during the first t - ttrig ˜ 10 d after the γ-ray trigger; (2) unexpected rebrightening of the forward shock radio emission at t - ttrig ˜ months; (3) lack of obvious evidence for jet precession, despite the misalignment typically expected between the angular momentum of the accretion disc and BH; (4) recent abrupt shut-off in the jet X-ray emission at t - ttrig ˜ 1.5 yr. Here, we show that all of these seemingly disparate mysteries are naturally resolved by one assumption: the presence of strong magnetic flux Φ• threading the BH. Just after the TD event, Φ• is dynamically weak relative to the high rate of fall-back accretion dot{M}, such that the accretion disc (jet) freely precesses about the BH axis = our line of sight. As dot{M} decreases, however, Φ• becomes dynamically important, leading to a state of `magnetically arrested disk' (MAD). MAD naturally aligns the jet with the BH spin, but only after an extended phase of violent rearrangement (jet wobbling), which in Swift J1644+57 starts a few days before the γ-ray trigger and explains the erratic early light curve. Indeed, the entire X-ray light curve can be fitted to the predicted power-law decay dot{M} ∝ t^{-α } (α ≃ 5/3 - 2.2) if the TD occurred a few weeks prior to the γ-ray trigger. Jet energy directed away from the line of sight, either prior to the trigger or during the jet alignment process, eventually manifests as the observed radio rebrightening, similar to an off-axis (orphan) γ-ray burst afterglow. As suggested recently, the late X-ray shut-off occurs when the disc transitions to a geometrically thin (jetless) state once

    The alveolates comprise three well-studied protist lineages of significant environmental, medical, and economical importance: apicomplexans (e.g., Plasmodium), dinoflagellates (e.g., Symbiodinium), and ciliates (e.g., Tetrahymena). These major lineages have evolved distinct and unusual characteristics, the origins of which have proved to be difficult evolutionary puzzles. Mitochondrial genomes are a prime example: all three groups depart from canonical form and content, but in different ways. Reconstructing such ancient transitions is difficult without deep-branching lineages that retain ancestral characteristics. Here we describe two such lineages and how they illuminate the ancestral state of alveolate mitochondrial genomes. We established five clonal cultures of colponemids, predatory alveolates without cultured representatives and molecular data. Colponemids represent at least two independent lineages at the phylum level in multilocus phylogenetic analysis; one sister to apicomplexans and dinoflagellates, and the other at a deeper position. A genome survey from one strain showed that ancestral state of the mitochondrial genomes in the three major alveolate lineages consisted of an unusual linear chromosome with telomeres and a substantially larger gene set than known alveolates. Colponemid sequences also identified several environmental lineages as colponemids, altogether suggesting an untapped potential for understanding the origin and evolution of apicomplexans, dinoflagellates, and ciliates.

    Chikungunya Fever is a mosquito-transmitted viral disease that causes fever, rash and musculoskeletal complaints. The latest may persist for several months, or even years or developed a relapsing course, that deserve an adequate treatment. Due to the large outbreak declared in the Caribbean in 2013, imported cases of Chikungunya as well as the risk of autochthonous transmission in case of available vectors have increased in non-endemic countries, like Spain. We described four cases of Chikungunya treated in our clinic.

    In recent years, there has been an increase in cases of imported helminthiasis in Spain because of two complementary causes: immigration and international travel. Although the prevalence of helminthiasis is high in the immigrant population, the risk of transmission to the Spanish population is low. In this review, we provide clues to aid in the diagnosis of the helminthiasis, highlighting the geographic characteristics, clinical findings and analytical results of the most frequent types. The low sensitivity of the classic parasitological diagnostic test, mainly in tissue helminthiasis, is described. In addition, the advantages and limitations of the common serological methods for detecting related circulating antigens and antibodies are presented. Certain molecular methods used in the diagnosis of imported helminthiasis and the best strategies for screening of this condition are discussed.

    As countries move toward malaria elimination, imported infections become increasingly significant as they often represent the majority of cases, can sustain transmission, cause resurgences, and lead to mortality. Here we review and critique current methods to prevent malaria importation in countries pursuing elimination and explore methods applied in other transmission settings and to other diseases that could be transferred to support malaria elimination. To improve intervention targeting we need a better understanding of the characteristics of populations importing infections and their patterns of migration, improved methods to reliably classify infections as imported or acquired locally, and ensure early and accurate diagnosis. The potential for onward transmission in the most receptive and vulnerable locations can be predicted through high-resolution risk mapping that can help malaria elimination or prevention of reintroduction programs target resources. Cross border and regional initiatives can be highly effective when based on an understanding of human and parasite movement. Ultimately, determining the optimal combinations of approaches to address malaria importation will require an evaluation of their impact, cost effectiveness, and operational feasibility.

    The European population of Greater Scaup Aythya marila has experienced an alarming, ~60% decline in numbers over the last two decades. The brackish lagoons of the Odra River Estuary (ORE) in the south-western Baltic Sea, represent an important area for the species during the non-breeding season in Europe. The lagoons regularly support over 20 000 Scaup, with peaks exceeding 100 000 (38%-70% of the population wintering in NW Europe and the highest number recorded in April 2011-105 700). In the ORE, Scaup feed almost exclusively on the non-native Zebra Mussel Dreissena polymorpha. This mussel was present in the ORE already in the 19th century and continues to be superabundant. Using the results of 22 Scaup censuses (November to April 2002/2003 to 2013/2014) from the whole ORE (523 km2 of water), we show that Scaup flocks follow areas with the greatest area of occurrence and biomass of the Zebra Mussel, while areas with low mussel densities are ignored. The numbers of Scaup in the ORE are primarily related to the area of Zebra Mussel occurrence on the lagoon's bottom (km2) in a non-linear fashion. Zebra Mussels were absolutely prevalent (97% of biomass) in the digestive tracts of birds unintentionally by-caught in fishing nets (n = 32). We estimate that Scaup alone consume an average of 5 400 tons of Zebra Mussels annually, which represents 5.6% of the total resources of the mussel in the ORE. Our results provide a clear picture of the strong dependence of the declining, migratory duck species on the non-native mussel, its primary food in the ORE. Our findings are particularly important as they can form the basis for the conservation action plan aimed at saving the north-western European populations of Scaup. PMID:26709707

    To ensure the correctness of network analysis methods, the network (as the input) has to be a sufficiently accurate representation of the underlying data. However, when representing sequential data from complex systems, such as global shipping traffic or Web clickstream traffic as networks, conventional network representations that implicitly assume the Markov property (first-order dependency) can quickly become limiting. This assumption holds that, when movements are simulated on the network, the next movement depends only on the current node, discounting the fact that the movement may depend on several previous steps. However, we show that data derived from many complex systems can show up to fifth-order dependencies. In these cases, the oversimplifying assumption of the first-order network representation can lead to inaccurate network analysis results. To address this problem, we propose the higher-order network (HON) representation that can discover and embed variable orders of dependencies in a network representation. Through a comprehensive empirical evaluation and analysis, we establish several desirable characteristics of HON, including accuracy, scalability, and direct compatibility with the existing suite of network analysis methods. We illustrate how HON can be applied to a broad variety of tasks, such as random walking, clustering, and ranking, and we demonstrate that, by using it as input, HON yields more accurate results without any modification to these tasks.

    Hydrological modelling studies often start with a qualitative sketch of the hydrological processes of a catchment. These so-called perceptual models are often pictured as hillslopes and are generalizations displaying only the dominant and relevant processes of a catchment or hillslope. The problem with these models is that they are prone to become too much predetermined by the designer's background and experience. Moreover it is difficult to know if that picture is correct and contains enough complexity to represent the system under study. Nevertheless, because of their qualitative form, perceptual models are easy to understand and can be an excellent tool for multidisciplinary exchange between researchers with different backgrounds, helping to identify the dominant structures and processes in a catchment. In our study we explore whether a perceptual model built upon an intensive field campaign may serve as a blueprint for setting up representative hillslopes in a hydrological model to reproduce the functioning of two distinctly different catchments. We use a physically-based 2D hillslope model which has proven capable to be driven by measured soil-hydrological parameters. A key asset of our approach is that the model structure itself remains a picture of the perceptual model, which is benchmarked against a) geo-physical images of the subsurface and b) observed dynamics of discharge, distributed state variables and fluxes (soil moisture, matric potential and sap flow). Within this approach we are able to set up two behavioral model structures which allow the simulation of the most important hydrological fluxes and state variables in good accordance with available observations within the 19.4 km2 large Colpach catchment and the 4.5 km2 large Wollefsbach catchment in Luxembourg without the necessity of calibration. This corroborates, contrary to the widespread opinion, that a) lower mesoscale catchments may be modelled by representative hillslopes and b) physically

    Representative sampling is important throughout the Defense Waste Processing Facility (DWPF) process, and the demonstrated success of the DWPF process to achieve glass product quality over the past two decades is a direct result of the quality of information obtained from the process. The objective of this report was to present sampling methods that the Savannah River Site (SRS) used to qualify waste being dispositioned at the DWPF. The goal was to emphasize the methodology, not a list of outcomes from those studies. This methodology includes proven methods for taking representative samples, the use of controlled analytical methods, and data interpretation and reporting that considers the uncertainty of all error sources. Numerous sampling studies were conducted during the development of the DWPF process and still continue to be performed in order to evaluate options for process improvement. Study designs were based on use of statistical tools applicable to the determination of uncertainties associated with the data needs. Successful designs are apt to be repeated, so this report chose only to include prototypic case studies that typify the characteristics of frequently used designs. Case studies have been presented for studying in-tank homogeneity, evaluating the suitability of sampler systems, determining factors that affect mixing and sampling, comparing the final waste glass product chemical composition and durability to that of the glass pour stream sample and other samples from process vessels, and assessing the uniformity of the chemical composition in the waste glass product. Many of these studies efficiently addressed more than one of these areas of concern associated with demonstrating sample representativeness and provide examples of statistical tools in use for DWPF. The time when many of these designs were implemented was in an age when the sampling ideas of Pierre Gy were not as widespread as they are today. Nonetheless, the engineers and

    This paper summarizes the development process and main characteristics of the Representative Concentration Pathways (RCPs), a set of four new scenarios developed for the climate modeling community as a basis for long-term and near-term modeling experiments. The four RCPs together span the range of year 2100 radiative forcing values found in the open literature, i.e. from 2.6 to 8.5 W/m2. The RCPs are the product of an innovative collaboration between integrated assessment modelers, climate modelers, terrestrial ecosystem modelers and emission inventory experts. The resulting product forms a comprehensive data set with high spatial and sectoral resolutions for the period extending to 2100. Land use and emissions of air pollutants and greenhouse gases are reported mostly at a 0.5 x 0.5 degree spatial resolution, with air pollutants also provided per sector (for well-mixed gases, a coarser resolution is used). The underlying integrated assessment model outputs for land use, atmospheric emissions and concentration data were harmonized across models and scenarios to ensure consistency with historical observations while preserving individual scenario trends. For most variables, the RCPs cover a wide range of the existing literature. The RCPs are supplemented with extensions (Extended Concentration Pathways, ECPs), which allow climate modeling experiments through the year 2300. The RCPs are an important development in climate research and provide a potential foundation for further research and assessment, including emissions mitigation and impact analysis.

  7. Analysis and Visualization of Internet QA Bulletin Boards Represented as Heterogeneous Networks

    NASA Astrophysics Data System (ADS)

    Murata, Tsuyoshi; Ikeya, Tomoyuki

    Visualizing and analyzing social interactions of CGM (Consumer Generated Media) are important for understanding overall activities on the internet. Social interactions are often represented as simple networks that are composed of homogeneous nodes and edges between them. However, related entities in real world are often not homogeneous. Such relations are naturally represented as heterogeneous networks composed of more than one kind of nodes and edges connecting them. In the case of CGM, for example, users and their contents constitute nodes of heterogeneous networks. There are related users (user communities) and related contents (contents communities) in the heterogeneous networks. Discovering both communities and finding correspondence among them will clarify the characteristics of the communites. This paper describes an attempt for visualizing and analyzing social interactions of Yahoo! Chiebukuro (Japanese Yahoo! Answers). New criteria for measuring correspondence between user communities and board communites are defined, and characteristics of both communities are analyzed using the criteria.

  8. Importance of macroprolactinemia in hyperprolactinemia.

    Macroprolactin is an antigen-antibody complex of higher molecular mass than prolactin (>150kDa), consisting of monomeric prolactin and immunoglobulin G. The term 'macroprolactinemia' is used when the concentration of macroprolactin exceeds 60% of the total serum prolactin concentration determined by polyethylene glycol precipitation. The gold standard technique for the diagnosis of macroprolactinemia is gel filtration chromatography. The prevalence of macroprolactinemia in hyperprolactinemic populations varies between 15% and 35%. Although the pathogenesis of these antibodies is not clear, it is possible that changes in the pituitary prolactin molecule represent increased antigenicity to the immune system, leading to the production of anti-prolactin antibodies. Mild hyperprolactinemia usually occurs because macroprolactin is not cleared readily from the circulation due to its higher molecular weight. Moreover, the hypothalamic negative feedback mechanism for autoantibody-bound prolactin is inactive because macroprolactin cannot access the hypothalamus, resulting in hyperprolactinemia. Reduced in-vivo bioactivity of macroprolactin may be the reason for the lack of hyperprolactinemic symptoms. It also seems that anti-prolactin autoantibodies may compete with prolactin molecules for receptor binding, resulting in low bioactivity. Additionally, the large molecular size of macroprolactin confined in the intravascular compartment prevents its passage through the capillary endothelium to the target cells, which may be the reason for the lack of symptoms. Macroprolactinemia is considered to be a benign clinical condition in patients with normal concentrations of bioactive monomeric prolactin, with a lack, or low incidence, of hyperprolactinemic symptoms and negative pituitary imaging. In such cases with resistance to anti-prolactinaemic drugs, no pharmacological treatment, diagnostic investigations or prolonged follow-up are required. However, macroprolactinemia may also

    The rhizocephalan barnacle, Sacculina carcini, is a common parasite of the European shore crab, Carcinus maenas, in which it causes significant detrimental physical and behavioral modifications. In the vast majority of cases, the external portion of the parasite is present in the form of a single sac-like externa; in rare cases, double or even triple externae may occur on the same individual host. Here, we use a highly variable DNA marker, the mitochondrial control region (CR), to investigate whether multiple externae in S. carcini represent infection by multiple parasites or asexual cloning developed by a single parasite individual. Sequences for multiple externae from C. maenas hosts from the Danish inlet, Limfjorden, and from the mud flates at Roscoff, France, were compared. In almost all cases, double or triple externae from an individual host yielded different haplotypes. In the few cases where identical haplotypes were identified from externae on a multiple-infected host, this always represented the most commonly found haplotype in the population. This indicates that in Sacculina carcini, the presence of multiple externae on a single host reflects infection by different individual parasites. A haplotype network of CR sequences also suggests a degree of geographical partitioning, with no shared haplotypes between the Limfjorden and Roscoff. Our data represent the first complete CR sequences for a rhizocephalan, and a unique gene order was also revealed. Although the utility of CR sequences for population-level work must be investigated further, the CR has proved a simple to use and highly variable marker for studies of S. carcini and can easily be applied to a variety of studies in this important parasite.

  7. Importance sampling : promises and limitations.

    SciTech Connect

    West, Nicholas J.; Swiler, Laura Painton

    2010-04-01

    Importance sampling is an unbiased sampling method used to sample random variables from different densities than originally defined. These importance sampling densities are constructed to pick 'important' values of input random variables to improve the estimation of a statistical response of interest, such as a mean or probability of failure. Conceptually, importance sampling is very attractive: for example one wants to generate more samples in a failure region when estimating failure probabilities. In practice, however, importance sampling can be challenging to implement efficiently, especially in a general framework that will allow solutions for many classes of problems. We are interested in the promises and limitations of importance sampling as applied to computationally expensive finite element simulations which are treated as 'black-box' codes. In this paper, we present a customized importance sampler that is meant to be used after an initial set of Latin Hypercube samples has been taken, to help refine a failure probability estimate. The importance sampling densities are constructed based on kernel density estimators. We examine importance sampling with respect to two main questions: is importance sampling efficient and accurate for situations where we can only afford small numbers of samples? And does importance sampling require the use of surrogate methods to generate a sufficient number of samples so that the importance sampling process does increase the accuracy of the failure probability estimate? We present various case studies to address these questions.

    ABSTRACT Poxviruses are large DNA viruses of vertebrates and insects causing disease in many animal species, including reptiles, birds, and mammals. Although poxvirus-like particles were detected in diseased farmed koi carp, ayu, and Atlantic salmon, their genetic relationships to poxviruses were not established. Here, we provide the first genome sequence of a fish poxvirus, which was isolated from farmed Atlantic salmon. In the present study, we used quantitative PCR and immunohistochemistry to determine aspects of salmon gill poxvirus disease, which are described here. The gill was the main target organ where immature and mature poxvirus particles were detected. The particles were detected in detaching, apoptotic respiratory epithelial cells preceding clinical disease in the form of lethargy, respiratory distress, and mortality. In moribund salmon, blocking of gas exchange would likely be caused by the adherence of respiratory lamellae and epithelial proliferation obstructing respiratory surfaces. The virus was not found in healthy salmon or in control fish with gill disease without apoptotic cells, although transmission remains to be demonstrated. PCR of archival tissue confirmed virus infection in 14 cases with gill apoptosis in Norway starting from 1995. Phylogenomic analyses showed that the fish poxvirus is the deepest available branch of chordopoxviruses. The virus genome encompasses most key chordopoxvirus genes that are required for genome replication and expression, although the gene order is substantially different from that in other chordopoxviruses. Nevertheless, many highly conserved chordopoxvirus genes involved in viral membrane biogenesis or virus-host interactions are missing. Instead, the salmon poxvirus carries numerous genes encoding unknown proteins, many of which have low sequence complexity and contain simple repeats suggestive of intrinsic disorder or distinct protein structures.

    1985-01-01

    A high level of automation is of paramount importance in most space operations. It is critical for unmanned missions and greatly increases the effectiveness of manned missions. However, although many functions can be automated by using advanced engineering techniques, others require complex reasoning, sensing, and manipulatory capabilities that go beyond this technology. Automation of fault diagnosis and malfunction handling is a case in point. The military have long been interested in this problem, and have developed automatic test equipment to aid in the maintenance of complex military hardware. These systems are all based on conventional software and engineering techniques. However, the effectiveness of such test equipment is severely limited. The equipment is inflexible and unresponsive to the skill level of the technicians using it. The diagnostic procedures cannot be matched to the exigencies of the current situation nor can they cope with reconfiguration or modification of the items under test. The diagnosis cannot be guided by useful advice from technicians and, when a fault cannot be isolated, no explanation is given as to the cause of failure. Because these systems perform a prescribed sequence of tests, they cannot utilize knowledge of a particular situation to focus attention on more likely trouble spots. Consequently, real-time performance is highly unsatisfactory. Furthermore, the cost of developing test software is substantial and time to maturation is excessive. Significant advances in artificial intelligence (AI) have recently led to the development of powerful and flexible reasoning systems, known as expert or knowledge-based systems. We have devised a powerful and theoretically sound scheme for representing and reasoning about procedural knowledge.

  10. An empirical multivariate log-normal distribution representing uncertainty of biokinetic parameters for 137Cs.

    2008-01-01

    A simplified biokinetic model for (137)Cs has six parameters representing transfer of material to and from various compartments. Using a Bayesian analysis, the joint probability distribution of these six parameters is determined empirically for two cases with quite a lot of bioassay data. The distribution is found to be a multivariate log-normal. Correlations between different parameters are obtained. The method utilises a fairly large number of pre-determined forward biokinetic calculations, whose results are stored in interpolation tables. Four different methods to sample the multidimensional parameter space with a limited number of samples are investigated: random, stratified, Latin Hypercube sampling with a uniform distribution of parameters and importance sampling using a lognormal distribution that approximates the posterior distribution. The importance sampling method gives much smaller sampling uncertainty. No sampling method-dependent differences are perceptible for the uniform distribution methods. PMID:18420573

    Most communicable diseases in Singapore have been brought under control and some eliminated. In recent years, an increasing proportion of the reported cases turned out to be imported. Between the period 1977 and 1982, 96% of malaria, 44% of paratyphoid, 32% of typhoid, 20% of leprosy, 11% of acute viral hepatitis, 7% of dengue fever/dengue haemorrhagic fever and 7% of cholera were imported. About 10% of the notified tuberculosis cases were non-residents while all the sporadic cases of poliomyelitis (except in 1977) and diphtheria (except in 1982) were contracted outside Singapore. The majority of the infections originated from Southeast Asia and the Indian subcontinent. The main groups of population with imported infections were local residents who travelled to the endemic areas without taking adequate preventive measures, foreign contract workers, and foreign seeking medical treatment in Singapore. Whether or not these imported cases would spread the infection to others in the community and cause epidemics depend on the virulence of the pathogen introduced, the susceptibility of the population and the environmental conditions which favour transmission of infection. Measures taken to reduce the risk of transmission include provision of a high standard of environmental sanitation, epidemiological surveillance to detect and eliminate the focus of infection; maintenance of a high level of herd immunity through immunisation; health education of the medical practitioners and of the public on the need for personal prophylaxis when travelling overseas; and screening of foreign contract workers and returning residents in special situations.

    The twinkling artifact is well known as a color Doppler artifact but it is still an unresolved phenomenon [Rahmouni et al., Radiology 1996;199:269-271 ; Atan et al., Astas Urol Esp 2001;35:396-402; Kamaya et al., AJR 2003;80:215-222]. Many factors affect the appearance of the twinkling artifact, such as the surface roughness of stones creating multiple reflections and a form of intrinsic noise known as clock jitter within the Doppler circuitry of the ultrasound equipment. However, no studies have reported on the twinkling artifact of breast microcalcifications. While considering these premises, I detected microcalcifications in the breast using twinkling artifacts that could not be detected on B-mode imaging. The twinkling artifact is a well-defined but not well-understood phenomenon that may assist in the detection of calcified foci. The phenomenon of the twinkling artifact is discussed here with regard to prospectively and retrospectively studied cases including experiments with a new ultrasound modality called multidetector-ultrasonography (MD-US). MD-US using detectability of the twinkling artifact in microcalcifications of the breast may play an important role in breast screening.

    The decision-making process in oil fields includes a step of risk analysis associated with the uncertainties present in the variables of the problem. Such uncertainties lead to hundreds, even thousands, of possible scenarios that are supposed to be analyzed so an effective production strategy can be selected. Given this high number of scenarios, a technique to reduce this set to a smaller, feasible subset of representative scenarios is imperative. The selected scenarios must be representative of the original set and also free of optimistic and pessimistic bias. This paper is devoted to propose an assisted methodology to identify representative models in oil fields. To do so, first a mathematical function was developed to model the representativeness of a subset of models with respect to the full set that characterizes the problem. Then, an optimization tool was implemented to identify the representative models of any problem, considering not only the cross-plots of the main output variables, but also the risk curves and the probability distribution of the attribute-levels of the problem. The proposed technique was applied to two benchmark cases and the results, evaluated by experts in the field, indicate that the obtained solutions are richer than those identified by previously adopted manual approaches.

    2016-08-01

    Malaria remains a serious public health problem in Shandong Province, China; therefore, it is important to explore the characteristics of the current malaria prevalence situation in the province. In this study, data of malaria cases reported in Shandong during 2012-2014 were analyzed, and Plasmodium species were confirmed by smear microscopy and nested-PCR. A total of 374 malaria cases were reported, 80.8% of which were reported from 6 prefectures. Of all cases, P. falciparum was dominant (81.3%), followed by P. vivax (11.8%); P. ovale and P. malariae together accounted for 6.4% of cases. Notably, for the first time since 2012, no indigenous case had been reported in Shandong Province, a situation that continued through 2014. Total 95.2% of cases were imported from Africa. The ratio of male/female was 92.5:1, and 96.8% of cases occurred in people 20-54 years of age. Farmers or laborers represented 77.5% of cases. No significant trends of monthly pattern were found in the reported cases. All patients were in good condition after treatment, except for 3 who died. These results indicate that imported malaria has increased significantly since 2012 in Shandong Province, especially for P. falciparum, and there is an emergence of species diversity. PMID:27658591

    The size of representative microstructural samples obtained from atomic force microscopy is addressed in this paper. The case of an archetypal one-dimensional nanolayered polymer blend is considered. Image analysis is performed on micrographs obtained through atomic force microscopy, yielding statistical data concerning morphological properties of the material. The variability in terms of microstructural morphology is due to the thermomechanical processing route. The statistical data is used in order to estimate sample size representativity, based on an asymptotic relationship relating the inherent point variance of the indicator function of one material phase to the statistical, size-dependent, ensemble variance of the same function. From the study of nanolayered material systems, the statistical approach was found to be an effective mean for discriminating and characterizing multiple scales of heterogeneity.

  5. Representing exact number visually using mental abacus.

    PubMed

    Frank, Michael C; Barner, David

    2012-02-01

    Mental abacus (MA) is a system for performing rapid and precise arithmetic by manipulating a mental representation of an abacus, a physical calculation device. Previous work has speculated that MA is based on visual imagery, suggesting that it might be a method of representing exact number nonlinguistically, but given the limitations on visual working memory, it is unknown how MA structures could be stored. We investigated the structure of the representations underlying MA in a group of children in India. Our results suggest that MA is represented in visual working memory by splitting the abacus into a series of columns, each of which is independently stored as a unit with its own detailed substructure. In addition, we show that the computations of practiced MA users (but not those of control participants) are relatively insensitive to verbal interference, consistent with the hypothesis that MA is a nonlinguistic format for exact numerical computation.

    Data structures and apparatuses to represent knowledge are disclosed. The processes can comprise labeling elements in a knowledge signature according to concepts in an ontology and populating the elements with confidence values. The data structures can comprise knowledge signatures stored on computer-readable media. The knowledge signatures comprise a matrix structure having elements labeled according to concepts in an ontology, wherein the value of the element represents a confidence that the concept is present in an information space. The apparatus can comprise a knowledge representation unit having at least one ontology stored on a computer-readable medium, at least one data-receiving device, and a processor configured to generate knowledge signatures by comparing datasets obtained by the data-receiving devices to the ontologies.

    The Representative Shuttle Environmental Control System (RSECS) program was conceived to provide NASA with a prototype system representative of the Shuttle Environmental Control System (ECS). Discussed are the RSECS program objectives, predicated on updating and adding to the early system as required to retain its usefulness during the Shuttle ECS development and qualification effort. Ultimately, RSECS will be replaced with a flight-designed system using either refurbished development or qualification equipment to provide NASA with a flight simulation capability during the Shuttle missions. The RSECS air revitalization subsystem and the waste management support subsystem are being tested. A water coolant subsystem and a freon coolant subsystem are in the development and planning phases.

    Four experiments were conducted to assess whether or not rhesus macaques (Macaca mulatta) could represent the unperceived movements of a stimulus. Subjects were tested on 2 computerized tasks, HOLE (monkeys) and LASER (humans and monkeys), in which subjects needed to chase or shoot at, respectively, a moving target that either remained visible or became invisible for a portion of its path of movement. Response patterns were analyzed and compared between target-visible and target-invisible conditions. Results of Experiments 1, 2, and 3 demonstrated that the monkeys are capable of extrapolating movement. That this extrapolation involved internal representation of the target's invisible movement was suggested but not confirmed. Experiment 4, however, demonstrated that the monkeys are capable of representing the invisible displacements of a stimulus.

    DSN Link Monitor & Control (LMC) operations consist primarily of executing procedures to configure, calibrate, test, and operate a communications link between an interplanetary spacecraft and its mission control center. Currently the LMC operators are responsible for integrating procedures into an end-to-end series of steps. The research presented in this paper is investigating new ways of specifying operations procedures that incorporate the insight of operations, engineering, and science personnel to improve mission operations. The paper describes the rationale for using Temporal Dependency Networks (TDN's) to represent the procedures, a description of how the data is acquired, and the knowledge engineering effort required to represent operations procedures. Results of operational tests of this concept, as implemented in the LMC Operator Assistant Prototype (LMCOA), are also presented.

  11. Semantic bifurcated importance field visualization

    2007-04-01

    While there are many good ways to map sensual reality to two dimensional displays, mapping non-physical and possibilistic information can be challenging. The advent of faster-than-real-time systems allow the predictive and possibilistic exploration of important factors that can affect the decision maker. Visualizing a compressed picture of the past and possible factors can assist the decision maker summarizing information in a cognitive based model thereby reducing clutter and perhaps related decision times. Our proposed semantic bifurcated importance field visualization uses saccadic eye motion models to partition the display into a possibilistic and sensed data vertically and spatial and semantic data horizontally. Saccadic eye movement precedes and prepares decision makers before nearly every directed action. Cognitive models for saccadic eye movement show that people prefer lateral to vertical saccadic movement. Studies have suggested that saccades may be coupled to momentary problem solving strategies. Also, the central 1.5 degrees of the visual field represents 100 times greater resolution that then peripheral field so concentrating factors can reduce unnecessary saccades. By packing information according to saccadic models, we can relate important decision factors reduce factor dimensionality and present the dense summary dimensions of semantic and importance. Inter and intra ballistics of the SBIFV provide important clues on how semantic packing assists in decision making. Future directions of SBIFV are to make the visualization reactive and conformal to saccades specializing targets to ballistics, such as dynamically filtering and highlighting verbal targets for left saccades and spatial targets for right saccades.

  12. The importance of embodied and operational energy and the use of renewable energy systems (RES) in the domestic sector in Greece: Case study, analysis of a design for a private residence in Athens

    2007-12-01

    The general framework of this thesis is set by addressing the environmental problems that several countries around the world are facing. Greece is undoubtedly one of them, particularly after failing to comply with its Kyoto Protocol commitments and thus meeting the relevant greenhouse gas emission targets. The project focuses on the built environment and more particularly on the domestic sector. The theoretical part contains the presentation of certain sustainable design principles and techniques, the implementation of which may result in a thermally comfortable and healthy interior, minimising the need for the use of non renewable forms of energy (e.g. oil) to heat and/or cool interior space. More specifically, the aim of this dissertation is to evaluate the environmental performance of an un-built residence, assumed to be built in the northern suburbs of Athens. For that reason its fabric is studied in TAS software the size of the openings, the type of glazing, the amount of certain materials (e.g. insulation and wall thicknesses) and so on are tested. The analysis indicates that the house's cooling and heating loads are reasonable and thus it can be described as environmentally friendly to a certain extent. Additionally, the project seeks to highlight the importance of the embodied and operational energy. This is achieved by studying in detail the case study and by calculating its embodied and operational energy, assuming that its lifetime is approximately 40 years. Furthermore, the residence's carbon footprint is calculated as well as the total structural cost, in an attempt to detect the best scenario that combines at the same time the smallest carbon footprint and cost. The analysis provides evidence that that can be achieved by using thicker insulation in the external concrete walls as well as in the roof. Finally, the use of geothermal and solar energy in the domestic sector is explored the former covering the space heating and cooling needs and the latter

    The primary objective of Project Activity ORD-FY04-012, “Yucca Mountain Climate Technical Support Representative,” was to provide the Office of Civilian Radioactive Waste Management (OCRWM) with expertise on past, present, and future climate scenarios and to support the technical elements of the Yucca Mountain Project (YMP) climate program. The Climate Technical Support Representative was to explain, defend, and interpret the YMP climate program to the various audiences during Site Recommendation and License Application. This technical support representative was to support DOE management in the preparation and review of documents, and to participate in comment response for the Final Environmental Impact Statement, the Site Recommendation Hearings, the NRC Sufficiency Comments, and other forums as designated by DOE management. Because the activity was terminated 12 months early and experience a 27% reduction in budget, it was not possible to complete all components of the tasks as originally envisioned. Activities not completed include the qualification of climate datasets and the production of a qualified technical report. The following final report is an unqualified summary of the activities that were completed given the reduced time and funding.

  14. Dehydrogenase GRD1 represents a novel component of the cellulase regulon in Trichoderma reesei (Hypocrea jecorina).

    Schuster, André; Kubicek, Christian P; Schmoll, Monika

    2011-07-01

    Trichoderma reesei (Hypocrea jecorina) is nowadays the most important industrial producer of cellulase and hemicellulase enzymes, which are used for pretreatment of cellulosic biomass for biofuel production. In this study, we introduce a novel component, GRD1 (glucose-ribitol dehydrogenase 1), which shows enzymatic activity on cellobiose and positively influences cellulase gene transcription, expression, and extracellular endo-1,4-β-D-glucanase activity. grd1 is differentially transcribed upon growth on cellulose and the induction of cellulase gene expression by sophorose. The transcription of grd1 is coregulated with that of cel7a (cbh1) under inducing conditions. GRD1 is further involved in carbon source utilization on several carbon sources, such as those involved in lactose and D-galactose catabolism, in several cases in a light-dependent manner. We conclude that GRD1 represents a novel enhancer of cellulase gene expression, which by coregulation with the major cellulase may act via optimization of inducing mechanisms.
