    Neuroendocrine tumors (neuroendokrine Tumoren) are rare entities. They can be found in all organs and show substantial biologic heterogeneity depending on involved organ, clinical symptoms and histopathologic morphology. Involvement of organs like larynx, cervix uteri, ovary, gallbladder, liver or kidney is extensively rare. The majority of neuroendokrine Tumoren are found in gastrointestinal tract and lung and are classified as neuroendokrine Tumoren of foregut (stomach, duodenum, pancreas, lung), midgut (jejunum, ileum, appendix, right side of the colon) and hindgut (left side of the colon, rectum). The role of imaging is to localize and delineate the primary tumor and to detect metastases. In the diagnosis of neuroendokrine Tumoren radiologic techniques like computed tomography (CT) and magnetic resonance imaging (MRI) are applied. In certain cases nuclear medicine techniques like somatostatin receptor scintigraphy (SRS) and positron emission tomography (PET) using radioactively labelled somatostatin analogues are used. The present article reviews characteristic imaging findings of neuroendokrine Tumoren of the gastrointestinal tract. (orig.)

    Gastroenteropancreatic neuroendocrine neoplasia (GEP-NEN) are a heterogeneous group of complex tumors, which is often difficult to classify due to heterogeneity and varying locations. Ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) and positron-emission tomography computed tomography (PET/CT) are available for the localization of NEN as well as for the staging. In particular, nuclear medical examination methods with somatostatin analogues are of great importance since radioactively labeled receptor ligands make tumors visible with high sensitivity. CT and MRT have high detection rates for GEP-NEN and have been further improved by developments such as diffusion weighted imaging. The nuclear medical methods, however, are superior in detection, especially in gastrointestinal NEN It is important for the radiologist to become acquainted with the NEN as they can occur ubiquitously in the abdomen and should be identified as such. Since GEP-NEN are predominantly hypervascularized, a biphasic examination technique is obligatory for contrast-enhanced cross-sectional imaging. PET/CT with somatostatin analogs should be used for further diagnosis. (orig.) [German] Gastroenteropankreatische neuroendokrine Neoplasien (GEP-NEN) sind eine heterogene Gruppe komplexer Tumoren, deren Einteilung aufgrund der Heterogenitaet und unterschiedlichen Lokalisation haeufig schwerfaellt. Fuer die Lokalisation der NEN sowie zur Ausbreitungsdiagnostik und Metastasensuche stehen Ultraschalldiagnostik, Computertomographie (CT), Magnetresonanztomographie (MRT) und die Positronenemissionstomographie-Computertomographie (PET-CT) zur Verfuegung. Insbesondere nuklearmedizinische Untersuchungsmethoden mit Somatostatinanaloga sind von hoher Wertigkeit, da sie ueber radioaktiv markierte Rezeptoliganden Tumoren mit hoher Sensitivitaet sichtbar machen. CT und MRT haben hohe Detektionsraten bei den GEP-NEN und konnten durch Weiterentwicklungen, wie Diffusionsbildgebung, weiter

    Neuroendocrine tumors (NET) of the pancreas are rare neoplasms, which arise from cells of the islets of Langerhans. The most common NET are the insulinoma, gastrinoma and hormone inactive NET. Very rare entities are the schwannoma, leiomyoma, teratoma, intrapancreatic lipoma, hemangioma and the intrapancreatic accessory spleen. Essential for therapy, which in most cases is difficult, are an exact localization and various modalities of imaging diagnostics. (orig.) [German] Neuroendokrine Tumoren (NET) des Pankreas sind seltene Neoplasien, die aus Zellen der Langerhans-Inseln entstehen. Zu den haeufigsten NET zaehlen Insulinome, Gastrinome und hormoninaktive NET.

    Pancreatic neuroendocrine neoplasms (NEN) account for 1-2 % of all pancreatic neoplasms and represent a rare differential diagnosis. While some pancreatic NEN are hormonally active and exhibit endocrine activity associated with characteristic symptoms, the majority are hormonally inactive. Imaging techniques such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) or as combined PET/CT play a crucial role in the initial diagnosis, therapy planning and control. Endoscopic ultrasound (EUS) and multiphase CT represent the reference methods for localization of the primary pancreatic tumor. Particularly in the evaluation of small liver lesions MRI is the method of choice. Somatostatin receptor scintigraphy and somatostatin receptor PET/CT are of particular value for whole body staging and special aspects of further therapy planning. (orig.) [German] Neuroendokrine Neoplasien (NEN) des Pankreas stellen mit einem Anteil von 1-2 % aller pankreatischen Tumoren eine seltene Differenzialdiagnose dar. Ein Teil der Tumoren ist hormonell aktiv und faellt klinisch durch charakteristische Symptome auf, wohingegen der ueberwiegende Anteil hormonell inaktiv ist. Bildgebende Verfahren wie Sonographie, Computertomographie (CT), Magnetresonanztomographie (MRT) und nicht zuletzt Positronenemissionstomographie (PET oder kombiniert als PET/CT) spielen eine zentrale Rolle fuer Erstdiagnose, Therapieplanung und -kontrolle. Die Endosonographie und die multiphasische CT stellen die Referenzmethoden zur Lokalisation des Primaertumors dar. Fuer die Differenzierung insbesondere kleiner Leberlaesionen bietet die MRT die hoechste Aussagekraft. Fuer das Ganzkoerperstaging und bestimmte Aspekte der Therapieplanung lassen sich die Somatostatinrezeptorszintigraphie und v. a. die Somatostatinrezeptor-PET/CT heranziehen. (orig.)

Es wurden in mehreren europäischen und US-amerikanischen Zentren insgesamt 230 Patienten mit einem Grad 1–2-Midgut-Tumor rekrutiert. Es ist aufgrund der bisherigen Daten evident, dass Patienten mit fortgeschrittenem Midgut-NET, welche mit Lutathera behandelt werden, ein statistisch signifikant längeres PFS aufweisen und es ist weiters sehr naheliegend, dass auch das OS deutlich positiv beeinflusst wird.

    Receptor PET/CT using {sup 68}Ga-labeled somatostatin analogues (DOTA-NOC, DOTA-TOC or DOTA-TATE) enables the highly sensitive molecular imaging of neuroendocrine tumors (NETs) based on the expression of somatostatin receptors and even the detection of receptor subtypes. Our experience after more than 3000 studies shows that receptor PET/CT has a significantly higher tumor detection rate than conventional scintigraphy (even in SPECT/CT technique), and that tumor lesions can be very accurately localized. By calculating standardized uptake values (SUV) - which are reproducible and investigator-independent - patients can be selected for peptide receptor radiotherapy and also the course after therapy can be controlled. Receptor-PET/CT is the most sensitive imaging modality for the detection of unknown primary tumors (CUP syndrome), which is especially true for the detection of neuroendocrine tumors of the pancreas and small bowel; whole-body staging (''one stop shop'') as well as restaging and selection of patients for peptide receptor radiotherapy can be performed using a patient-friendly procedure (examination finished within one hour) exposing the patient to less radiation than whole-body CT scanning. The {sup 68}Ge/{sup 68}Ga generator has proved very reliable over the years - even in a hospital environment. The effective costs for {sup 68}Ga labeled somatostatin analogues might be less than for scintigraphic agents, provided a certain number of studies per year are performed. The development of new tumor-specific peptides as well as of other DOTA- or NOTA-coupled radiopharmaceuticals opens a new avenue into the future: finally, the {sup 68}Ga generator could play a similar important role for PET/CT as did the {sup 99m}Tc-Generator for conventional gamma camera imaging over the last decades.

    Lipids A, the lipophilic partial structure of lipopolysaccharides, induce regression of several tumor types in animal models. Rather than exerting direct cytotoxic effect, these compounds trigger the immune system which in turn stimulates secretion of cytokines, and activates the inducible nitric oxide synthase, as well as immune cell infiltration of tumors. OM-174 is an analogue of lipid A with dual action on Toll-like receptors 2 and 4. In an experimental model of peritoneal carcinomatosis induced in BDIX rats by intraperitoneal injection of syngeneic PROb colon cancer cells, it induced a complete regression of tumors. The present phase I trial was conducted to determine the maximum tolerated dose, the recommended phase II dose and biological response associated with OM-174 administered as intravenous infusion. Patients received OM-174 twice weekly for a total of 5, 10 or 15 injections of either 600, 800 or 1000 μg/m 2 . Blood samples for pharmacokinetic analysis and cytokine dosages were collected. NK cells activity and Toll-like receptors 4 polymorphism analysis were also performed. Seventeen patients were included. The highest dose administered was 1000 μg/m 2 repeated in 15 injections. The most common toxicities were a chills, fever, nausea/vomiting, diarrhea, fatigue and headache. No patient experienced haematological side effects. As no dose limiting toxicity was observed, despite a grade 3 respiratory complication, the maximal tolerated dose and recommended dose were not established. Three patients exhibited disease stabilization with a mean duration of 4 months. Pharmacokinetic profile of OM-174 was characterized by a low distribution volume and clearance. Analysis of TLR 4 polymorphysm showed that most (16/17) patients carried the wild type alleles. A progressive increase in NK cell number and activity was observed only in patients receiving 1000 μg/m 2 of OM-174. A peak of IL-8 and IL-10 concentrations were observed after each OM-174 injection.

    The Space Station Freedom Program (SSFP) Operations Management System (OMS) will automate major management functions which coordinate the operations of onboard systems, elements and payloads. The objectives of OMS are to improve safety, reliability and productivity while reducing maintenance and operations cost. This will be accomplished by using advanced automation techniques to automate much of the activity currently performed by the flight crew and ground personnel. OMS requirements have been organized into five task groups: (1) Planning, Execution and Replanning; (2) Data Gathering, Preprocessing and Storage; (3) Testing and Training; (4) Resource Management; and (5) Caution and Warning and Fault Management for onboard subsystems. The scope of this prototyping effort falls within the Fault Management requirements group. The prototyping will be performed in two phases. Phase 1 is the development of an onboard communications network fault detection, isolation, and reconfiguration (FDIR) system. Phase 2 will incorporate global FDIR for onboard systems. Research into the applicability of expert systems, object-oriented programming, fuzzy sets, neural networks and other advanced techniques will be conducted. The goals and technical approach for this new SSFP research project are discussed here.

    An Operations Management System (OMS) is being designed for Space Station Freedom to improve productivity, reliability, and safety while reducing operations and maintenance costs. Central to the concept is a short term plan containing mixes of man-readable and machine-executable procedures used in an environment of distributed processing and execution. An OMS event evaluator to check upcoming short-term plan events for validity of execution is under development. The first version checks time and resource constraints against operational conditions for current or expected stations. In work are the handling of environmental and other operational constraints, as well as detailed modeling of resources and station operational states. The Ada Program also has the ability to reschedule all or part of the events.

  11. Kampen om matfatet og matproduksjonen

    Directory of Open Access Journals (Sweden)

    Hans Morten Haugen

    2013-05-01

    Full Text Available Antallet sultne i verden har økt, selv om det kan diskuteres om det i dag er en høyere eller lavere andel som lider under sult enn for seks år siden – før matprisøkningen. Alle er uansett enige om at det samlet sett produseres nok mat i verden til at alle kan få dekket sine ernæringsbehov. Artikkelen viser at to hovedretninger i debatten om matproduksjon står mot hverandre. Den dominerende retningen fokuserer primært på matsikkerhet, forstått som økt matproduksjon og økt handel med mat. Den andre retningen argumenterer for at interessene og rettighetene for de mest sårbare må ha forrang i politiske prioriteringer, og at de sårbare sikres best med en strategi basert på menneskerettigheter. Artikkelen drøfter landfordeling, økt bruk av genteknologi i landbruket og nedbygging av handelshindre for landbruksprodukter. Industrialisering av landbruket og liberalisering av handelen med landbruksvarer kan gi gode resultater på makronivå – på kort sikt. Dersom målet er å fremme situasjonen for de mest sårbare og samtidig møte klimautfordringene er løsningen en nedenfra-tilnærming, som til nå er blitt ignorert av de fleste stater.Nøkkelord: retten til mat, matsikkerhet, klima, Verdens handelsorganisasjon, FNs tusenårsmålEnglish summary: The struggle over food intake and food productionThe number of hungry persons in the world has increased – although it is debatable whether there is currently a higher or lower proportion of suffering from hunger than six years ago – before the food price increases. All agree that the overall production of food in the world is adequate for everyone's nutritional needs. The article demonstrates that there are two main approaches in the debate on food production. The dominant approach focuses primarily on food security, understood as increased food production and increased food trade. The other approach argues that the interests and rights of the most vulnerable must prevail, and that

    % aller gastrointestinalen Tumoren ausmacht. Fuer die Lokalisation des Primaertumors als auch fuer das Staging endokriner Tumoren spielen neben der Ultraschalldiagnostik die Computertomographie (CT), die Magnetresonanztomographie (MRT) und die Positronenemissionstomographie-Computertomographie (PET-CT) eine entscheidende Rolle. Neben dem Primaerstaging lassen sich mithilfe der PET-CT mit Somatostatinanaloga auch die Indikation fuer eine Radionuklidtherapie stellen und der Therapieverlauf dokumentieren. Das CT-Enteroklysma erreicht nach der Literatur bei Duenndarmtumoren bis 3 cm eine Sensitivitaet von 84,7 %, eine Spezifitaet von 96,9 %; mit der Magnetresonanzenterographie (MRE) kann ein neuroendokriner Tumor (NET) des Duenndarms in 93,3 % der Faelle lokalisiert werden. Laut Literatur ist die MRT bei der Detektion pankreatischer NET mit einer Sensitivitaet zwischen 74 und 100 % der CT ueberlegen. Die PET-CT ermoeglicht die Detektion sehr kleiner Primaertumoren und gilt als sensitivste Methode zur Lokalisationsdiagnostik. Bei der Detektion von Lebermetastasen ist die MRT der CT und der PET-CT ueberlegen. Aufgabe der bildgebenden Diagnostik ist es, neben der Lokalisation des Primaertumors und dem Staging, Therapien zu planen und ein Therapieansprechen zu dokumentieren. Die Wahl der verschiedenen bildgebenden Verfahren hierfuer ist abhaengig von der Lokalisation des Primaertumors. Da gastroenteropankreatische neuroendokrine Tumoren (GEP-NET) ueberwiegend hypervaskularisiert sind, ist eine biphasische Untersuchungstechnik nach Kontrastmittelgabe in arterieller und venoeser Phase fuer die Abklaerung von Primaertumoren und Metastasen sowohl in der CT wie in der MRT obligat. Fuer das Ganzkoerperstaging kommen vorrangig CT und PET-CT zum Einsatz. (orig.)

    2001-04-01

    Neuroendocrine tumors are characterized immunocytochemically by the expression of different peptides and biogenic amines. Hormones induce their biological action by binding to and stimulating specific membrane-associated receptors for e.g. somatostatin. The presence of somatostatin receptors (SR) has been described mainly in endocrine glands and the central nervous system. Interestingly, a large variety of human tumors, including gastroenteropancreatic (GEP) tumors and medullary thyroid carcinomas (MTC) also express a high density of SR and can be imaged with [{sup 111}In-DTPA-D-Phe{sup 1}]-pentetreotide. Cell proliferative activity is an important indicator of the growth of various malignant tumors associated with a poorer prognosis and Ki-67 expression. {sup 18}F-FDG is a marker of tumor viability, based upon the increased glycolysis that is associated with malignancy as compared with normal tissue. SR-containing neuroendocrine tumors are well-differentiated and tend to grow slowly. Furthermore, these tumors demonstrate inverse relationship between in vivo SR expression, cell proliferation (low Ki-67 expression) and FDG uptake (normal biodistribution). In comparison, less differentiated tumors, e.g. atypical carcinoids or MTC with increasing CEA levels show mitotic activity (high levels of Ki-67 immunoreactivity and increased FDG uptake) and often lack of SR. In conclusion, SR scintigraphy has been shown to localize well-differentiated neuroendocrine tumors. In contrast, PET imaging is valuable for predicting malignancy only in less differentiated tumors with incresed glucose metabolism. Therefore, an additional F-18 FDG PET should be performed if SR scintigraphy (GEP tumors) or combined imaging using [{sup 111}In-DTPA-D-Phe{sup 1}]-pentetreotide and {sup 99m}Tc(V)-DMSA (MTC) is negative.

    RéSUMé: OBJECTIF : Déterminer les taux d'accord et la reproductibilité intra et inter-observateurs des classifications OMS 1973 et OMS 2004 des tumeurs urothéliales papillaires de la vessie. MATéRIEL ET MéTHODES : Cent deux cas de tumeurs urothéliales papillaires de stade pTa/pT1 ont été étudiés. Deux pathologistes ont revu les lames et ont établi le grade tumoral selon les deux classifications OMS 1973 et OMS 2004. En cas de désaccord, les deux évaluateurs ont procédé à une lecture commune au microscope en double tête afin d'aboutir à un grade consensuel selon les deux classifications. La variabilité intra-observateur a été étudiée chez l'un des deux évaluateurs qui a procédé à la relecture des lames un mois après sa première lecture. Les taux d'accord entre les deux pathologistes pour chaque catégorie de grade ont été déterminés et la reproductibilité des deux classifications a été évaluée à l'aide du coefficient kappa. Une valeur de 0 à 0,2 était interprétée comme un désaccord absolu, de 0,21 à 0,4, un accord faible, de 0,41 à 0,6, un accord modéré, de 0,61 à 0,8, un accord considérable, et de 0,8 à 1, un accord absolu. RéSULTATS : Selon la classification OMS 1973, les proportions des grades G1, G2 et G3 étaient respectivement de 40,2 %, 50 % et 9,8 %. Selon la classification OMS 2004, les proportions respectives des tumeurs de faible potentiel de malignité, des carcinomes de bas grade et des carcinomes de haut grade de malignité étaient de 23,5 %, 60,8 % et 15,7 %. La reproductibilité intra-observateur était excellente pour les deux classifications (accord absolu). Les taux d'accord entre les deux pathologistes étaient meilleurs pour la classification OMS 2004 (kappa = 0,7) que pour la classification OMS 1973 (kappa = 0,51). La reproductibilité entre observateurs de la classification OMS 2004 est supérieure à celle de 1973. La reproductibilité intra-observateur est excellente pour les deux

    Science.gov (United States)

    Kurulugama, Ruwan T.; Nachtigall, Fabiane M.; Valentine, Stephen J.; Clemmer, David E.

    2011-11-01

    A new, two-dimensional overtone mobility spectrometry (OMS-OMS) instrument is described for the analysis of complex peptide mixtures. OMS separations are based on the differences in mobilities of ions in the gas phase. The method utilizes multiple drift regions with modulated drift fields such that only ions with appropriate mobilities are transmitted to the detector. Here we describe a hybrid OMS-OMS combination that utilizes two independently operated OMS regions that are separated by an ion activation region. Mobility-selected ions from the first OMS region are exposed to energizing collisions and may undergo structural transitions before entering the second OMS region. This method generates additional peak capacity and allows for higher selectivity compared with the one-dimensional OMS method. We demonstrate the approach using a three-protein tryptic digest spiked with the peptide Substance P. The [M + 3H]3+ ion from Substance P can be completely isolated from other components in this complex mixture prior to introduction into the mass spectrometer.

    Sakowski, Piotr

    2012-01-01

    This paper presents the results of an assessment of the Polish occupational medicine service (OMS) system made by OMS nurses. The survey was carried out on a random group of OMS nurses. OMS nurses form a professional group comprised of rather experienced personnel. In the opinion of almost 70% of respondents the system guarantees good occupational heath care, whereas 20% took the opposite view. The great majority of respondents think that all employees have to undergo mandatory prophylactic examinations. The nurses have rather critical opinion about the legal regulations pertaining to occupational health care--their number and complexity, and also express negative opinion about the quality of cooperation with employers (who are contractors for OMS units). OMS nurses believe that prophylactic examinations are the strongest point of the system. They are often the only opportunity for establishing contact between an employee and a physician and learning about diseases he or she was previously unaware of. Although the general assessment of the OMS system is rather positive, it is not free of shortcomings. Improvements in such fields as legislation, financing of service, professional attitude towards responsibilities of the OMS staff, cooperation with employers (contractors) and primary health care units would undoubtedly result in even better assessment, and what is more important in better functioning of the Polish OMS system.

    Infrared spectra of the matrix isolated OMS, OM(η(2)-SO), and OM(η(2)-SO)(η(2)-SO(2)) (M = Ti, Zr, Hf) molecules were observed following laser-ablated metal atom reactions with SO(2) during condensation in solid argon and neon. The assignments for the major vibrational modes were confirmed by appropriate S(18)O(2) and (34)SO(2) isotopic shifts, and density functional vibrational frequency calculations (B3LYP and BPW91). Bonding in the initial OM(η(2)-SO) reaction products and in the OM(η(2)-SO)(η(2)-SO(2)) adduct molecules with unusual chiral structures is discussed.

  3. Herbart om oppdragelse, formbarhet og takt

    Directory of Open Access Journals (Sweden)

    Lars Løvlie

    2015-04-01

    Full Text Available Jeg presenterer her en analyse og tolkning av Herbarts syn på oppdragelse og danning, med feste i to av hans begreper: formbarhet – Bildsamkeit – og takt. Det første kaster lys over forholdet mellom lærer og elev, det andre først og fremst over forholdet mellom teori og praksis. For ham, som for forgjengeren Immanuel Kant, dreiet det seg om subjektivitet og frihet, eller mer konkret: Hvordan oppdra til autonomi der det også kreves tvang? Så vidt jeg kan se, bruker Herbart de to grunnbegrepene nettopp til å bestemme det paradoksale og uferdige forholdet mellom frihet og tvang. Han forklarer det som et åpent forhold eller relasjon som ikke har en bestemt begynnelse og heller ikke en bestemt konklusjon. Verken tradisjon eller vitenskap kan ved seg selv realisere dette råderommet. Han tenker seg et frirom der kunnskap, intuisjon og skjønn spiller på lag i oppdragelsen. Tradisjonen henger gjerne igjen i gamle fordommer, vitenskapen fanges i teori og abstrakt skjema, og ingen av dem dekker de unike situasjonene som nyskaper forholdet mellom voksne og barn. Herbart stilte seg åpen til spørsmål som ikke løses ved styring og kontroll, og spør implisitt om ikke vi også kan gjøre det samme.

  6. Meditation on OM: Relevance from ancient texts and contemporary science

    Directory of Open Access Journals (Sweden)

    Kumar Sanjay

    2010-01-01

    Full Text Available Background: In Indian scriptures the sacred syllable Om is the primordial sound from which all other sounds and creation emerge which signifies the Supreme Power. Aims: To explore the significance of the syllable OM from ancient texts and effects of OM meditation in contemporary science. Descriptions from ancient texts: The descriptions of Om have been taken from four Upanisads (Mundaka, Mandukya, Svetasvatara, and Katha, the Bhagvad Gita, and Patanjali′s Yoga Sutras. Scientific studies on Om: Autonomic and respiratory studies suggest that there is a combination of mental alertness with physiological rest during the practice of Om meditation. Evoked potentials studies suggest a decrease in sensory transmission time at the level of the auditory association cortices, along with recruitment of more neurons at mesencephalic-diencephalic levels. Conclusion: It is considered that a person who realizes Om, merges with the Absolute. Scientific studies on Om suggest that the mental repetition of Om results in physiological alertness, and increased sensitivity to sensory transmission.

    The study focuses on the use of an orbital maneuvering system (OMS) payload bay kit (PBK) designed to utilize OMS tanks identical to those currently employed in the Orbiter OMS pods. Emphasis is placed on payload deployment capability and payload servicing/reboost capability augmentation from the point of view of payload mass, maximum deployment altitudes, and initial retrieval and final deployment altitudes. The deployment, servicing, and reboost requirements of the Hubble Space Telescope and Advanced X-ray and Astrophysics Facility are analyzed in order to show the benefits an OMS PBK can provide for these missions. It is shown that OMS PBKs can provide the required capability enhancement necessary to support deployment, reboost, and servicing of payloads requiring altitudes greater than 325 nautical miles.

  19. Selective hydrogenation of halogenated arenes using porous manganese oxide (OMS-2) and platinum supported OMS-2 catalysts.

    McManus, Iain J; Daly, Helen; Manyar, Haresh G; Taylor, S F Rebecca; Thompson, Jillian M; Hardacre, Christopher

    2016-07-04

    Porous manganese oxide (OMS-2) and platinum supported on OMS-2 catalysts have been shown to facilitate the hydrogenation of the nitro group in chloronitrobenzene to give chloroaniline with no dehalogenation. Complete conversion was obtained within 2 h at 25 °C and, although the rate of reaction increased with increasing temperature up to 100 °C, the selectivity to chloroaniline remained at 99.0%. Use of Pd/OMS-2 or Pt/Al2O3 resulted in significant dechlorination even at 25 °C and 2 bar hydrogen pressure giving a selectivity to chloroaniline of 34.5% and 77.8%, respectively, at complete conversion. This demonstrates the potential of using platinum group metal free catalysts for the selective hydrogenation of halogenated aromatics. Two pathways were observed for the analogous nitrobenzene hydrogenation depending on the catalyst used. The hydrogenation of nitrobenzene was found to follow a direct pathway to aniline and nitrosobenzene over Pd/OMS-2 in contrast to the OMS and Pt/OMS-2 catalysts which resulted in formation of nitrosobenzene, azoxybenzene and azobenzene/hydrazobenzene intermediates before complete conversion to aniline. These results indicate that for Pt/OMS-2 the hydrogenation proceeds predominantly over the support with the metal acting to dissociate hydrogen. In the case of Pd/OMS-2 both the hydrogenation and hydrogen adsorption occur on the metal sites.

    Purpose This study aimed to investigate the effect of OM-101 on the fibrotic response occurring in proliferative vitreoretinopathy (PVR) in an animal model. Methods Antifibrotic effect of OM-101 was investigated in vivo. As control, eight weeks old c57black mice underwent intravitreal injection with Hepes (group A) or dispase (0.3 units), to induce retinal detachment (RD) and PVR. The dispase-injected mice were randomly divided into two groups B and C (N = 25 mice); in group C, the eyes were treated with intravitreal injection of OM-101 (3 μl), and group B with PBS, as a control. After additional five days, mice were injected with the same initial treatment. Three days later, mice were euthanized, and the eyes were enucleated and processed for histological analysis. Results Intravitreal injection of dispase caused RD in 64% of the mice in group B, and 93% of those mice had PVR. Only 32% of mice treated with OM-101 and dispase (group C) developed RD, and only 25% of those developed PVR. Conclusions OM-101 was found effective in reducing the incidence of RD and PVR maintaining the normal architecture of the retina. This study suggests that OM-101 is a potentially effective and safe drug for the treatment of PVR patients. PMID:29109865

  10. Ten-year rollover of San Onofre inservice testing program for pumps and valves to OM-6 and OM-10

    International Nuclear Information System (INIS)

    Croy, P.A.; Fischetti, S.; Chiang, D.; Schofield, P.; Barney, D.

    1994-01-01

    The Pump and Valve Inservice Testing (IST) Program Sat San Onofre, Units 2 and 3, was updated for the second 120-month interval from August 1993 to April 1994. The U.S. Nuclear Regulatory Commission (USNRC) approved the OM-6 and OM-10 Codes in mid-1992. The project for the rollover to these new Codes included several elements: (a) a review of the differences between IWV/IWP and OM-6/OM-10, (b) a comprehensive audit of the IST Program scope for valves, (c) creation of the program and supporting basis documents, the Relief Requests, and implementing procedures, (d) interdivisional coordination, (e) submittal to the USNRC, and (f) training. Subsections IWV and IWP have been used and essentially unchanged for over a decade. The new Code (Parts 1, 6, and 10 called OM-1, OM-6, and OM-10) includes several significant changes from the old Code. Our group identified these differences and drafted revised and reorganized Inservice Testing (IST) Program documents. We also considered USNRC Generic Letter 89-04 (GL 89-04), open-quotes Guidance on Developing Acceptable Inservice Testing Programsclose quotes, and NUREG-1482, Guidelines for Inservice Testing at Nuclear Power Plants, while revising the program. There were six pump relief requires and 13 valve relief requests in the program for the first 10-year interval. For the revised program we needed only one pump relief request (and no valve relief requests). Converting to the 1989 edition of the ASME Code did not require changes to the technical specifications. We revised our Updated Final Safety Analysis Report (UFSAR) to reflect the IST Program for the second 10-year interval. UFSAR changes were minor, consisting of updated references to the Code edition and 10 CFR 50.55a(f), open-quotes Inservice Testing Requirementsclose quotes

For MOVs this includes those that perform a specific function in shutting down a reactor to the safe shutdown condition, maintaining the safe shutdown condition, and mitigating the consequences of an accident. This paper will present a brief history of industry and regulatory activities related to MOVs and the development of Code requirements to address weaknesses in earlier versions of the OM Code. The paper will discuss the MOV requirements contained in the 2009 version of ASME OM Code, specifically Mandatory Appendix III and OMN-1, Revision 1.

  7. New directions and challenges for the O&M committee

    Energy Technology Data Exchange (ETDEWEB)

    Pelletier, J.P.

    1996-12-01

    In the second half of the decade of the nineties, the imperative of finding new ways to improve efficiency while maintaining safety is taking on a new urgency. The looming deregulation of the electric industry and the expected competition in the power production business fuels this urgency. The recently completed ASME research in the area of Risk-Based Inservice Testing offers the Operations and Maintenance (O&M) Committee an opportunity to meet this challenge. This opportunity, however, offers its own challenges. New ways of thinking about inservice testing and new technical skills will be needed to successfully incorporate this technology into Code documents. It will not be adequate to rely solely on incorporation of risk-based methods into the Code to meet this challenge. A thorough self assessment of what O&M does, how it is done, and the value added will help assure that the directions which are pursued do, indeed, meet the challenge ahead.

    Investigation of Space Transportation System (STS) Atmospheric Luminosities (ISAL) experiment documentation includes vertical tail and orbital maneuvering system (OMS) pods with surface glow against the blackness of space. This glowing scene was provided by a long duration exposure with a 35mm camera aimed toward the tail of the Earth-orbiting Challenger, Orbiter Vehicle (OV) 099. OV-099 was maneuvered to a 120-nautical-mile altitude and flown with open payload bay (PLB) in the velocity vector for the conducting of a test titled, 'Evaluation of Oxygen Interaction with Materials (EOIM)'. Atomic oxygen within the low orbital environment is known to be extremely reactive when in contact with solid surfaces. In the darkened area between the camera and the glowing OMS pods and vertical stabilizer are two trays of test materials.

  16. Ultra-Wideband Optical Modulation Spectrometer (OMS) Development

    Science.gov (United States)

    Gardner, Jonathan (Technical Monitor); Tolls, Volker

    2004-01-01

    The optical modulation spectrometer (OMS) is a novel, highly efficient, low mass backend for heterodyne receiver systems. Current and future heterodyne receiver systems operating at frequencies up to a few THz require broadband spectrometer backends to achieve spectral resolutions of R approximately 10(exp 5) to 10(exp 6) to carry out many important astronomical investigations. Among these are observations of broad emission and absorption lines from extra-galactic objects at high redshifts, spectral line surveys, and observations of planetary atmospheres. Many of these lines are pressure or velocity broadened with either large half-widths or line wings extending over several GHz. Current backend systems can cover the needed bandwidth only by combining the output of several spectrometers, each with typically up to 1 GHz bandwidth, or by combining several frequency-shifted spectra taken with a single spectrometer. An ultra-wideband optical modulation spectrometer with 10 - 40 GHz bandwidth will enable broadband ob- servations without the limitations and disadvantages of hybrid spectrometers. Spectrometers like the OMS will be important for both ground-based observatories and future space missions like the Single Aperture Far-Infrared Telescope (SAFIR) which might carry IR/submm array heterodyne receiver systems requiring a spectrometer for each array pixel. Small size, low mass and small power consumption are extremely important for space missions. This report summarizes the specifications developed for the OMS and lists already identified commercial parts. The report starts with a review of the principle of operation, then describes the most important components and their specifications which were derived from theory, and finishes with a conclusion and outlook.

  1. Seabed Filter Feasibility Study of Om Almisk Island

    KAUST Repository

    Sesler, Kathryn

    2012-06-01

    Freshwater access has always been and is continuing to be a severe problem in desert coastal regions, despite the fact that they have an unlimited supply of easily accessible saline water. Water desalination plants are well established and heavily relied upon throughout the Middle East, Saudi Arabia in particular. However, water desalination tends to be a very expensive and energy intensive solution to the problem. The transition from using open water intake systems and all of the pretreatment processes that they require, to using seabed water filters as an intake, would potentially reduce the lifetime costs, energy consumption, and environmental impacts commonly associated with water desalination. This is because the filtration process that the seabed filter generates, serves as sufficient pretreatment for seawater as well as eliminating any risk of entrainment or impingement of marine organisms. The main objective of this research is to conduct a feasibility study on Om Almisk Island, an island off the coast of King Abdullah University of Science and Technology (KAUST), to determine if it would be a suitable location to construct a seabed water filter as a replacement for the current open water intake. The Om Almisk Island site was evaluated through collection of sand samples over a radial grid around Om Almisk Island and sample analysis using grain size distribution, porosity, and hydraulic conductivity. The lack of mud, high hydraulic conductivity, proximity to KAUST, and the shallow waters of the sandy apron surrounding Om Almisk Island make this an ideal location for a seabed water filter to be used as an intake and pretreatment for the KAUST desalination plant. This location also has low tide change and the presence of benthic macrofauna to create bioturbation in the sediments, which could inhibit the growth of a schmutzdecke. If this biological layer forms, it could drastically reduce the hydraulic conductivity of the system. Due to the high hydraulic

    To test for hypothesized disease- and treatment-induced changes in cytokines and adhesion molecules in children with opsoclonus-myoclonus syndrome (OMS). Multiplex bead assay technology was used for simultaneous measurement of 34 soluble cytokines in cerebrospinal fluid (CSF) and serum. Soluble intercellular adhesion molecule-1 (sICAM-1) and vascular cell adhesion molecule-1 (sVCAM-1) were measured by ELISA. In total, there were 388 children (239 OMS, 114 controls, and 35 other inflammatory neurological disorders (OIND)). In untreated OMS, mean CSF IL-6 was elevated 2.3-fold, but 67-fold in OIND, without significant differences in other CSF cytokines. Mean serum concentrations of sIL-2Ra (+50%) and CXCL1 (+70%) (pOMS than controls (p=0.005), as was serum CCL11 and IL-13 in treated OMS. Mean CSF CCL4 and IL-1Ra were selectively higher in IVIg-treated OMS (p≤0.0001). CSF sICAM-1 was elevated only in OIND (3.3-fold); serum sICAM-1 was higher in untreated OMS (+21%); and sVCAM-1 was not affected. No correlations with OMS severity or duration were identified. Novel cytokine, cytokine antagonist, and soluble adhesion molecule abnormalities due to OMS or treatment were found. However, the normality of much of the data strengthens previous findings implicating B cell mechanisms. Copyright © 2013 Elsevier B.V. All rights reserved.

    Using a panel of seven brain cell-specific biomarkers in cerebrospinal fluid (CSF), pediatric opsoclonus-myoclonus syndrome (OMS) (n=234) was compared to pediatric non-inflammatory neurological controls (n=84) and other inflammatory neurological disorders (OIND) (n=44). Only CSF NFL was elevated in untreated OMS versus controls (+83%). It was 87% higher in OIND than in OMS. On combination treatment with front-loaded ACTH, IVIg, rituximab, median CSF NFL decreased by 60% to control levels. These biochemical data suggest neuronal/axonal injury in some children with OMS without indicators of astrogliosis, and reduction on sufficient immunotherapy. Copyright © 2013 Elsevier B.V.

    2013-12-01

    Understanding the organic matter/organic carbon (OM/OC) ratio in ambient particulate matter (PM) is critical to achieve mass closure in routine PM measurements, to assess the sources of and the degree of chemical processing organic aerosol particles have undergone, and to relate ambient pollutant concentrations to health effects. Of particular interest is how the OM/OC ratio varies in the urban environment, where strong spatial and temporal gradients in source emissions are common. We provide results of near-roadway high-time-resolution PM1 OM concentration and OM/OC ratio observations during January 2008 at Fyfe Elementary School in Las Vegas, NV, 18 m from the U.S. 95 freeway soundwall, measured with an Aerodyne high-resolution time-of-flight aerosol mass spectrometer (HR-AMS). The average OM/OC ratio was 1.54 (+/- 0.20 standard deviation), typical of environments with a low amount of secondary aerosol formation. The 2-min average OM/OC ratios varied between 1.17 and 2.67, and daily average OM/OC ratios varied between 1.44 and 1.73. The ratios were highest during periods of low OM concentrations and generally low during periods of high OM concentrations. OM/OC ratios were low (1.52 +/- 0.14, on average) during the morning rush hour (average OM = 2.4 microg/m3), when vehicular emissions dominate this near-road measurement site. The ratios were slightly lower (1.46 +/- 0.10) in the evening (average OM = 6.3 microg/m3), when a combination of vehicular and fresh residential biomass burning emissions was typically present during times with temperature inversions. The hourly averaged OM/OC ratio peaked at 1.66 at midday. OM concentrations were similar regardless of whether the monitoring site was downwind or upwind of the adjacent freeway throughout the day, though they were higher during stagnant conditions (wind speed < 0.5 m/sec). The OM/OC ratio generally varied more with time of day than with wind direction and speed.

  6. Epidemiologisk forskning om uførepensjon i Norden

    2010-01-01

    Full Text Available En relativ stor andel av befolkningen i yrkesaktiv alder i de nordiske landene mottar uførepensjon, og i Norge er det en klar tendens til økning. Parallelt med dette har interessen for forskning rundt uførepensjon som fenomen økt. Vi har i denne studien beskrevet den epidemiologiske forskningen om uførepensjon i Norden. I en systematisk litteraturgjennomgang fant vi 118 aktuelle artikler. Alle de nordiske landene er godt representert. Kohortstudier med uførepensjon som endepunkt utgjorde hovedvekten av materialet, hvor 67 var populasjonsbaserte mens 29 tok utgangspunkt i selekterte pasientpopulasjoner. I alt seks kohortstudier benyttet uførepensjon som eksponering. Vi fant videre syv kasus-kontrollstudier og ni forsøk. Det er betydelig dokumentasjon på at ulike sykdommer og helseplager er assosiert med økt risiko for uførhet, i tillegg til at sosioøkonomiske og arbeidsrelaterte forhold er av betydning. Gjennomgangen viser at den epidemiologiske forskningen for det meste har rettet blikket mot individuelle årsaker til uførepensjonering. Selv om denne forskningen er viktig, kan den neppe forklare økningen vi har sett i det siste tiåret. Den videre forskningen bør utforske nærmere hvordan individuell sårbarhet ender i utstøtelse fra arbeidslivet. Med tanke på den omfattende forskningen om årsaker på dette feltet, bør man også i større grad gjennomføre forsøk for å bedre utsatte gruppers arbeidsdeltakelse.Bjørngaard JH, Krokstad S, Johnsen R, Karlsen AO, Pape K, Støver M, Sund E, Westin S.

    Full Text Available Den direkte transmission af levende begivenheder har altid været TV- mediets særlige styrke, hvad enten det drejer sig om fodboldkampe, Lørdagskanalen eller kongebrylluper. Medieforskerne har da også interesseret sig for fjernsynets formidling af sportsbegivenheder og der er blevet lavet analyser af Kanaludsendelserne. Men hverken i Danmark eller andre steder har forskerne fundet det interessant at undersøge de store, ceremonielle mediebegivenheder. Det er Dayan & Katz´ projekt at udfylde dette tomrum i medie- og kul- turforskningen: Hvad er det, der fascinerer millioner ved disse TV- ceremonier, der ofte ikke blot henvender sig til et enkelt lands seere, men transmitteres til og ses af store dele af verden? Hvordan fungere disse begivenheder - hvad enten det drejer sig om Præsident Kennedys begravelse, Sadats besøg i Jerusalem, Månelandingen eller Watergate- høringerne - ideologisk, og hvilke interesser tjener de dermed i den politiske offentlighed? I denne artikel, der er et bearbejdet uddrag af den bog, projektet skal munde ud i, beskæftiger Dayan & Katz sig især med det de kalder "transformative" mediebegivenheder, dvs. TV-ceremonier der markerer, at et samfund står ved en tærskel mellem den herskende orden og en ny mulig orden, og som selv er et aktivt og aktiverende bidrag til forvand- lingen af kulturelle opfattelser og værdier. Artiklens perpektiv er udpræget tværvidenskabeligt, idet der trækkes på såvel kulturantropologiske (Levi-Strauss, Geertz, Turner som filosofiske (Bakhtin, Baudrillard, sprogteoretiske (Austin og traditionelt samfunds- videnskabelige/mediesociologiske (Boorstin arbejder. I artiklens første halvdel foretages der en afgrænsning af transformative over for andre ceremonielle begivenheder. I anden halvdel gennemgås de fem faser, som udgør transformative begivenheders typiske struktur. Artiklen er bearbejdet af Jørgen Bang og Kim Schrøder. Den er oversat af Kim Schrøder.

    Cryptomelane type manganese dioxides (α-MnO2, OMS-2) are interesting potential cathode materials due to the ability of their one dimensional (1D) tunnels to reversibly host various cations including Li+and an accessible stable 3+/4+ redox couple. Here, we synthesized metal cation free OMS-2 materials where the tunnels were occupied by only water and hydronium ions. Water was subsequently removed from the tunnels. Cation free OMS-2 and Dry-OMS-2 were used as cathodes in Li based batteries to investigate the role of tunnel water on their electrochemistry. The initial discharge capacity was higher for Dry-OMS-2 (252 mAh/g) compared to OMS-2 (194 mAh/g), however, after 100 cycles Dry-OMS-2 and OMS-2 delivered 137 mAh/g and 134 mAh/g, respectively. Li+ion diffusion was more facile for Dry-OMS as evidenced by rate capability, at 400 mA/g. Dry-OMS-2 delivered 135mAh/g whereas OMS-2 delivered ~115 mAh/g. This first report of the impact of tunnel water on the electrochemistry of OMS-2 type materials demonstrates that the presence of tunnel water in OMS-2 type materials negatively impacts the electrochemistry.

    Opsoclonus-myoclonus syndrome (OMS) is a rare neurological disease in childhood which can be associated with neuroblastoma. Since autoantibodies have been detected in some patients with OMS, an autoimmune etiology is suspected. We compared the prevalence of autoimmune disorders and autoantibodies in parents of children with OMS and in a group of controls of same age and sex. Autoimmune diseases were found in 15.8% of the parents of OMS children, but only in 2.0% of the controls (pOMS parents (42.8% vs. 8.0%, pOMS parents also had significantly more autoantibodies against CNS structures than the controls (pOMS and may also hint to a genetic susceptibility for OMS.

    Full Text Available Å forske med kunsten innebærer ikke bare valget av visse metoder for bruk i forskningsprosessen, men også om å ha til disposisjon spesifikke måter å tenke om metode. I denne artikkelen vil jeg synliggjøre en tenkemåte fundert i arbeidet med en skjønnlitterær lesesirkel for lærerstudenter, og min egen erfaring som improvisasjonsmusiker. Jazzens begrep om jam blir løftet frem som omdreiningspunkt for tenkemåten, som ellers har sitt teoretiske utspring i den franske filosofen Gilles Deleuze’s forestilling om bliven. Denne vitale forestillingen innebærer at verden produseres kontinuerlig, noe forskeren også bidrar til. Koblingen mellom jam, litteratur og Deleuze synliggjør dessuten en måte å tenke om metode på som understreker at det å forske med kunsten ikke bare betyr å forske på kunsten, men at kunsten på ulike måter kan virke inn på selve forskningen og slik også bidra til å affirmere verden i sin bliven. I tillegg til å tilby en måte å tenke om metode for den som skal forske med kunsten, er hensikten med artikkelen å gjøre forskeren bevisst sin egen tenkning om metode, noe som er viktig siden denne skaper mulighetsbetingelser for metodevalg og -bruk.

    Low valent manganese species and surface oxygen vacancies in OMS-2 play an important role in catalytic reactions, and it is highly desirable and challenging to develop a feasible strategy of increasing the Mn(II) and Mn(III) species concentration in the oxide. Herein, the OMS-2/g-C3N4 hybrids (OMS-2/CN) were prepared by a facile refluxing approach. It was found that the MnOx precursor from the reaction of KMnO4 and MnSO4 was transformed into OMS-2 nanofibers with the formation of more Mn(II) and Mn(III) species in OMS-2 and the destruction and oxidation of g-C3N4. The hybrids exhibited higher efficiency for pollutants degradation in the presence of PMS than the pure OMS-2 or g-C3N4. There was a linear correlation between the specific initial rate and the ratio of Mn(II + III)/Mn(IV). Mechanism investigation indicated that high active manganese species or caged radicals were produced through the oxidation of Mn(II) and Mn(III) by PMS and contributed to the degradation reaction. During five consecutive cycles, the catalyst exhibited good reusability and stability. Therefore, the OMS-2/CN hybrids are promising catalysts for wastewater treatment with PMS as the oxidant.

    Sodium octahedral molecular sieve nanorods (Na-OMS-2) were prepared through a facile hydrothermal method. The effects of reaction temperature and duration on particle sizes of the products were investigated. The electrochemical performance of samples was studied by constant current charge–discharge tests as cathode material for Li-ion batteries (LIBs). The initial discharge capacity of Na-OMS-2 is 123.4 mAh g−1 and the capacity retention was 123.9 mAh g−1 after 100 cycles. The result demonstrates that Na-OMS-2 cathode material behaves a good cycling stability.

    Perturbation of cell adhesion can be essential for tumor cell invasion and metastasis, but the current knowledge on the gene expression of molecules that mediate cell adhesion in canine oral tumors is limited. The present study aimed to investigate changes in the gene expression of cell adhesion molecules (E-cadherin or CDH1, syndecan 1 or SDC1, NECTIN2 and NECTIN4), matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs), in canine oral tumors, including benign tumors, oral melanoma (OM) and non-tonsillar oral squamous cell carcinoma (OSCC), by quantitative real-time reverse transcription PCR. When compared with the normal gingival controls, decreased CDH1, SDC1 and NECTIN4 expression levels were observed in OSCC and OM, reflecting a possible role as cell adhesion molecules and tumor suppressors in canine oral cancers in contrast to the upregulation of MMP2 expression. Downregulated MMP7 was specifically revealed in the OM group. In the late-stage OM, the positive correlation of MMP7 and CDH1 expression was noticed as well as that of SDC1 and NECTIN4. Enhanced TIMP1 expression was shown in all tumor groups with prominent expression in the benign tumors and the early-stage OM. MMP14 expression was notable in the early-stage OM. Higher MMP9 and TIMP1 expression was observed in the acanthomatous ameloblastoma. In conclusion, this study revealed that the altered expression of cell adhesion molecules, MMP7 and MMP2 was correlated with clinicopathologic features in canine oral cancers whereas TIMP1 and MMP14 expression was probably associated with early-stage tumors; therefore, these genes might serve as molecular markers for canine oral tumors.

    2015-11-01

    This document outlines the foundation for developing language that can be utilized in an Equipment Availability Guarantee, typically included in an O&M services agreement between a PV system or plant owner and an O&M services provider, or operator. Many of the current PV O&M service agreement Availability Guarantees are based on contracts used for traditional power generation, which create challenges for owners and operators due to the variable nature of grid-tied photovoltaic generating technologies. This report documents language used in early PV availability guarantees and presents best practices and equations that can be used to more openly communicate how the reliability of the PV system and plant equipment can be expressed in an availability guarantee. This work will improve the bankability of PV systems by providing greater transparency into the equipment reliability state to all parties involved in an O&M services contract.

    The nanostructure of Ce doped OMS-2 plays a very important role in its catalytic property. We demonstrate by density functional theory (DFT) calculations that the unique nanostructure of the Ce ion substituted OMS-2 with Mn vacancy in the framework is beneficial for the improvement of catalytic activity, while the nanostructure of the Ce ion substituted OMS-2 without defects are detrimental to the catalytic activity. We establish a novel and facile strategy of synthesizing these unique Ce ion substituted OMS-2 nanostructure with Mn vacancies in the framework by hydrothermal redox reaction between Ce(NO3)3 and KMnO4 with KMnO4/Ce(NO3)3 at a molar ratio of 3 : 1 at 120 °C. Compared to pure OMS-2, the produced catalyst of Ce ion substituted OMS-2 ultrathin nanorods exhibits an enormous enhancement in the catalytic activity for benzene oxidation, which is evidenced by a significant decrease (ΔT50 = 100 °C, ΔT90 = 129 °C) in the reaction temperature of T50 and T90 (corresponding to the benzene conversion = 50% and 90%), which is considerably more efficient than the expensive supported noble metal catalyst (Pt/Al2O3). We combine both theoretical and experimental evidence to provide a new physical insight into the significant effect due to the defects induced by the Ce ion substitution on the catalytic activity of OMS-2. The formation of unique Ce ion substituted OMS-2 nanostructure with Mn vacancies in the framework leads to a significant enhancement of the lattice oxygen activity, thus tremendously increasing the catalytic activity.The nanostructure of Ce doped OMS-2 plays a very important role in its catalytic property.

    In 208 children with opsoclonus-myoclonus syndrome (OMS), CSF IgG oligoclonal bands (OCB) and 22 immunomarkers in CSF and 21 in serum/blood were measured. In 36 untreated OMS, 58% were OCB(+), whereas 55% of treated OMS were OCB(-). OCB positivity or negativity did not alter concentrations or frequencies of immunomarkers. The phenotypes of OCB(+) and OCB(-) patients were not distinctive. CSF B cells were expanded in untreated OMS regardless of OCB positivity. These data reveal a much higher frequency of OCB positivity in untreated OMS than previously realized and a disconnect between intrathecal OCB and inflammatory mediator production. Copyright © 2018.

  8. Quantification of amine functional groups and their influence on OM/OC in the IMPROVE network

    2018-01-01

    Recently, we developed a method using FT-IR spectroscopy coupled with partial least squares (PLS) regression to measure the four most abundant organic functional groups, aliphatic C-H, alcohol OH, carboxylic acid OH and carbonyl C=O, in atmospheric particulate matter. These functional groups are summed to estimate organic matter (OM) while the carbon from the functional groups is summed to estimate organic carbon (OC). With this method, OM and OM/OC can be estimated for each sample rather than relying on one assumed value to convert OC measurements to OM. This study continues the development of the FT-IR and PLS method for estimating OM and OM/OC by including the amine functional group. Amines are ubiquitous in the atmosphere and come from motor vehicle exhaust, animal husbandry, biomass burning, and vegetation among other sources. In this study, calibration standards for amines are produced by aerosolizing individual amine compounds and collecting them on PTFE filters using an IMPROVE sampler, thereby mimicking the filter media and collection geometry of ambient standards. The moles of amine functional group on each standard and a narrow range of amine-specific wavenumbers in the FT-IR spectra (wavenumber range 1 550-1 500 cm-1) are used to develop a PLS calibration model. The PLS model is validated using three methods: prediction of a set of laboratory standards not included in the model, a peak height analysis and a PLS model with a broader wavenumber range. The model is then applied to the ambient samples collected throughout 2013 from 16 IMPROVE sites in the USA. Urban sites have higher amine concentrations than most rural sites, but amine functional groups account for a lower fraction of OM at urban sites. Amine concentrations, contributions to OM and seasonality vary by site and sample. Amine has a small impact on the annual average OM/OC for urban sites, but for some rural sites including amine in the OM/OC calculations increased OM/OC by 0.1 or more.

    Spinal tumors are uncommon lesions but may cause significant morbidity in terms of limb dysfunction. In establishing the differential diagnosis for a spinal lesion, location is the most important feature, but the clinical presentation and the patient's age and gender are also important. Magnetic resonance (MR) imaging plays a central role in the imaging of spinal tumors, easily allowing tumors to be classified as extradural, intradural-extramedullary or intramedullary, which is very useful in tumor characterization. In the evaluation of lesions of the osseous spine both computed tomography (CT) and MR are important. We describe the most common spinal tumors in detail. In general, extradural lesions are the most common with metastasis being the most frequent. Intradural tumors are rare, and the majority is extramedullary, with meningiomas and nerve sheath tumors being the most frequent. Intramedullary tumors are uncommon spinal tumors. Astrocytomas and ependymomas comprise the majority of the intramedullary tumors. The most important tumors are documented with appropriate high quality CT or MR images and the characteristics of these tumors are also summarized in a comprehensive table. Finally we illustrate the use of the new World Health Organization (WHO) classification of neoplasms affecting the central nervous system

    The human orbital muscle (OM) is not readily accessible during ordinary anatomical teaching because of insufficient time and difficulties encountered in the preparation. Accordingly, its few anatomical descriptions are supported only by drawings, but not by photographs. The aim of this study was to present OM in dissected anatomic specimens in more detail. Following microscope-assisted dissection, its location, syntopy and morphology were analyzed in 88 orbits of 51 cadavers. Together with the periorbital connective tissue OM filled the infraorbital fissure (IOF) and extended back to the cavernous sinus. As a new finding, we here report that in 34% of the orbits we observed OM-fibers, which proceeded from IOF caudally to the facies infratemporalis of the maxilla. OM had a mean width of 4±1mm, a mean length of 22±5mm and its mean mass was 0.22±0.19g. The subsequent histological analysis of all specimens showed features of smooth muscle tissue: long, spindle-like cells with a centrally located cell nucleus (hematoxylin-eosin staining) which were innervated by tyrosine-hydroxylase immunopositive adrenergic fibers. We conclude that precise knowledge on OM might be very helpful not only to students in medicine and dentistry during anatomical dissection courses, but also to head and neck surgeons, ear-nose-throat specialists and neurosurgeons working in this field.

  4. Contribution of effluent organic matter (EfOM) to ultrafiltration (UF) membrane fouling: Isolation, characterization, and fouling effect of EfOM fractions

    KAUST Repository

    Zheng, Xing

    2014-11-01

    EfOM has been regarded as a major organic foulant resulting in UF membrane fouling in wastewater reclamation. To investigate fouling potential of different EfOM fractions, the present study isolated EfOM into hydrophobic neutrals (HPO-N), colloids, hydrophobic acids (HPO-A), transphilic neutrals and acids (TPI), and hydrophilics (HPI), and tested their fouling effect in both salt solution and pure water during ultrafiltration (UF). Major functional groups and chemical structure of the isolates were identified using Fourier transform infrared spectroscopy (FT-IR) and solid-state carbon nuclear magnetic resonance (13C NMR) analysis. The influence of the isolation process on the properties of EfOM fractions was minor because the raw and reconstituted secondary effluents were found similar with respect to UV absorbance, molecular size distribution, and fluorescence character. In membrane filtration tests, unified membrane fouling index (UMFI) and hydraulic resistance were used to quantify irreversible fouling potential of different water samples. Results show that under similar DOC level in feed water, colloids present much more irreversible fouling than other fractions. The fouling effect of the isolates is related to their size, chemical properties, and solution chemistry. Further investigations have identified that the interaction between colloids and other fractions also influences the performance of colloids in fouling phenomena. © 2014 Elsevier Ltd.

    OMS-2 nanorod catalysts were synthesized by a hydrothermal redox reaction method using MnSO4 (OMS-2-SO4) and Mn(CH3COO)2 (OMS-2-AC) as precursors. SO4(2-)-doped OMS-2-AC catalysts with different SO4(2-) concentrations were prepared next by adding (NH4)2SO4 solution into OMS-2-AC samples to investigate the effect of the anion SO4(2-) on the OMS-2-AC catalyst. All catalysts were then tested for the catalytic oxidation of ethanol. The OMS-2-SO4 catalyst synthesized demonstrated much better activity than OMS-2-AC. The SO4(2-) doping greatly influenced the activity of the OMS-2-AC catalyst, with a dramatic promotion of activity for suitable concentration of SO4(2-) (SO4/catalyst=0.5% W/W). The samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), inductively coupled plasma optical emission spectroscopy (ICP-OES), NH3-TPD and H2-TPR techniques. The results showed that the presence of a suitable amount of SO4(2-) species in the OMS-2-AC catalyst could decrease the Mn-O bond strength and also enhance the lattice oxygen and acid site concentrations, which then effectively promoted the catalytic activity of OMS-2-AC toward ethanol oxidation. Thus it was confirmed that the better catalytic performance of OMS-2-SO4 compared to OMS-2-AC is due to the presence of some residual SO4(2-) species in OMS-2-SO4 samples. Copyright © 2015.

    B-cell dysregulation has been implicated but not fully characterized in pediatric opsoclonus-myoclonus syndrome (OMS), a neuroblastoma-associated neuroinflammatory disorder. To assess the role of B-cell activating factor (BAFF) and a proliferation-inducing ligand (APRIL), two critical B cell-modulating cytokines, as potential biomarkers of disease activity and treatment biomarkers in OMS. Soluble BAFF and APRIL were measured in cerebrospinal fluid (CSF) and serum by ELISA in 433 children (296 OMS, 109 controls, 28 other inflammatory neurological disorders (OIND)). BAFF-R receptors on circulating CD19+ B cells were measured by flow cytometry. A blinded scorer rated motor severity on the OMS Evaluation Scale. Immunotherapies were evaluated cross-sectionally and longitudinally. The mean CSF BAFF concentration, which was elevated in untreated OMS and OIND, correlated with OMS severity category (P = 0.006), and reduction by adrenocorticotropic hormone or corticotropin (ACTH) (-61%) or corticosteroids (-38%) was seen at each level of severity. In contrast, CSF APRIL was normal in OMS and OIND and unaffected by immunotherapy. When the entire OMS dataset was dichotomized into 'high' versus 'normal' CSF BAFF concentration, the phenotype of the high group included greater motor severity and number of CSF oligoclonal bands, and a higher concentration of inflammatory chemokines CXCL13 and CXCL10 in CSF and CXCL9 and CCL21 in serum. Serum APRIL was 6.7-fold higher in the intravenous immunoglobulins (IVIg) group, whereas serum BAFF was 2.6-fold higher in the rituximab group. The frequency of B cell BAFF-R expression was similar in untreated and treated OMS. Longitudinal studies of CSF BAFF revealed a significant decline in ACTH-treated patients (with or without rituximab) (P OMS displayed heterogeneity in CSF BAFF expression, which met many but not all criteria as a potential biomarker of disease activity. We speculate that CSF BAFF may have more utility in a biomarker panel

    Full Text Available Environmental factors play a major role on atopic dermatitis (AD which shows a constant rise in prevalence in western countries over the last decades. The Hygiene Hypothesis suggesting an inverse relationship between incidence of infections and the increase in atopic diseases in these countries, is one of the working hypothesis proposed to explain this trend.This study tested the efficacy and safety of oral administration of the bacterial lysate OM-85 (Broncho-Vaxom®, Broncho-Munal®, Ommunal®, Paxoral®, Vaxoral®, in the treatment of established AD in children.Children aged 6 months to 7 years, with confirmed AD diagnosis, were randomized in a double-blind, placebo-controlled trial to receive, in addition to conventional treatment with emollients and topical corticosteroids, 3.5mg of the bacterial extract OM-85 or placebo daily for 9 months. The primary end-point was the difference between groups in the occurrence of new flares (NF during the study period, evaluated by Hazard Ratio (HR derived from conditional Cox proportional hazard regression models accounting for repeated events.Among the 179 randomized children, 170 were analysed, 88 in the OM-85 and 82 in the placebo group. As expected most children in both treatment groups experienced at least 1 NF during the study period (75 (85% patients in the OM-85 group and 72 (88% in the placebo group. Patients treated with OM-85 as adjuvant therapy had significantly fewer and delayed NFs (HR of repeated flares = 0.80; 95% confidence interval (CI: 0.67-0.96, also when potential confounding factors, as family history of atopy and corticosteroids use, were taken into account (HR = 0.82; 95% CI: 0.69-0.98. No major side effect was reported, with comparable and good tolerability for OM-85 and placebo.Results show an adjuvant therapeutic effect of a well standardized bacterial lysate OM-85 on established AD.

    As greater numbers of photovoltaic (PV) systems are being installed, operations & maintenance (O&M) activities will need to be performed to ensure the PV system is operating as designed over its useful lifetime. To mitigate risks to PV system availability and performance, standardized procedures for O&M activities are needed to ensure high reliability and long-term system bankability. Efforts are just getting underway to address the need for standard O&M procedures as PV gains a larger share of U.S. generation capacity. Due to the existing landscape of how and where PV is installed, including distributed generation from small and medium PV systems, as well as large, centralized utility-scale PV, O&M activities will require different levels of expertise and reporting, making standards even more important. This report summarizes recent efforts made by solar industry stakeholders to identify the existing standards and best practices applied to solar PV O&M activities, and determine the gaps that have yet to be, or are currently being addressed by industry.

    To study aberrant B cell trafficking into the CSF in opsoclonus-myoclonus syndrome (OMS), chemoattractants CXCL13 and CXCL12, and B cell frequency and CXCR5 expression, were evaluated. CSF CXCL13 concentration and the CSF/serum ratio were higher in untreated OMS than controls, related directly to OMS severity and inversely to OMS duration, and correlated with CSF B cell frequency and oligoclonal bands. CXCL12 showed the opposite pattern. Selective accumulation of CXCR5+ memory B cells in CSF was found. In ACTH-treated OMS, CXCL13, but not CXCL12, was lower. These data implicate the chemokine/chemoreceptor pair CXCL13/CXR5 in B cell recruitment to the CNS in OMS. CXCL13 and CXCL12 may serve as reciprocal biomarkers of disease activity, but CXCL13 also had utility as a treatment biomarker. Copyright © 2011 Elsevier B.V. All rights reserved.

    The LHCb experiment will upgrade its DAQ system to a trigger less, 40MHz read-out after LS2. To be able to process the approximately 40Tbit/s of data we will require a massive computing farm. This computing farm can not be installed underground, in the vicinity of the detector anymore due to the enormous power and cooling requirements. An affordable data transport solution has to be found to carry the data from the detector to the new data center on the surface. The distance to cover is estimated to be between 300 and 400 meters. We evaluated the feasibility of using the 5Gbit/s Versatile Link to cover the full distance over OM3 and OM4 quality fibres and will present our results.

    There are few trained veterinary radiation oncologists and the expense of facilities has limited the extent to which this modality is used. In recent years, a few cobalt teletherapy units and megavoltage x-ray units have been employed in larger veterinary institutions. In addition, some radiation oncologists of human medical institutions are interested and willing to cooperate with veterinarians in the treatment of animal tumors. Carefully designed studies of the response of animal tumors to new modalities serve two valuable purposes. First, these studies may lead to improved tumor control in companion animals. Second, these studies may have important implications to the improvement of therapy of human tumors. Much remains to be learned of animal tumor biology so that appropriate model systems can be described for such studies. Many of the latter studies can be sponsored by agencies interested in the improvement of cancer management

    The effects of the bacterial extract OM-85 on the respiratory burst, intracellular calcium and the stress response have been investigated in human peripheral blood monocytes from normal donors. Activation of the respiratory burst during bacterial phagocytosis has been previously associated with heat shock/stress proteins synthesis. Whereas OM-85 stimulated superoxide production and increased Ca2+ mobilization, it fared to induce synthesis of classical HSPs. The lack of stress protein induction was observed even in the presence of iron which potentiates both oxidative injury and stress protein induction during bacterial phagocytosis. However OM-85 induced a 75–78 kDa protein, which is likely to be a glucose regulated protein (GRP78), and enhanced intracellular expression of interleukin-lβ precursor. PMID:18472933

    Full Text Available Hvilken rolle spiller medierne i hverdagslivet blandt etniske minoriteter i Danmark? Lidt firkantet kan man spørge: er mennesker af anden etnisk oprindelse mere integrerede, når de foretrækker dansk produceret fjern- syn, end når de foretrækker oprindelseslandets tv? Kultursociologen Connie Carøe Christiansen har i denne artikel trukket nogle af pointerne op fra en undersøgelse, som Danmarks Radio bestilte hos Socialforsk- ningsinstituttet om netop nogle af ovenstående spørgsmål. Carøe, en af rapportens hovedforfattere, analyserer medieforbruget hos etniske mino- riteter i Danmark i lyset af diskussioner om multikulturalisme og social integration. Artiklen er således inspireret af diskussioner om transnationa- lisme og diaspora-identiteter.

    To demonstrate the health economic impact of OM-85, a bacterial lysates based immunostimulant, for its approved indications in China. A cost-effectiveness decision tree model was constructed comparing OM-85 with the best supportive care/placebo therapy for managing the acute exacerbation of chronic bronchitis and rhinosinusitis in the Chinese population. Clinical efficacy and adverse events (AE) data were included in the model based on a thorough literature review. All localized direct treatment costs, including drug cost, AE costs, and medical treatment costs for underlining diseases were included from a Chinese third party payer perspective. A Key Opinion Leaders (KOL) survey was conducted with 20 senior physicians specialized in respiratory, ENT, allergy, and immunology fields from tertiary hospitals in Beijing, Shanghai, Guangzhou, Hangzhou, Shenyang, and Wuhan to validate the local treatment costs. Incremental cost-effectiveness ratio (ICER) was calculated based on the above efficacy and cost information. OM-85 is a cost-effective therapy when compared with placebo (standard care). OM-85 can treat/prevent one additional full episode exacerbation of chronic bronchitis and one additional full episode exacerbation of rhinosinusitis with only additional costs of RMB 653 and RMB 1182.84, respectively. In comparison, each acute exacerbation of chronic bronchitis will cost RMB 4510.10, and each acute exacerbation of rhinosinuisitis will cost RMB 1807.21 in a Chinese clinical management setting. One-way sensitivity analyses were performed and the ICER result was demonstrated to be consistent. OM 85 reduces acute exacerbations among patients with chronic bronchitis and chronic rhinosinusitis when compared with Placebo (standard care). From a Chinese payer perspective, OM 85 is a cost-effective therapy in the clinical management of both chronic bronchitis and rhinosinusitis in the adult population.

    Cryptomelane-type octahedral molecular sieve manganese oxide (OMS-2) possesses high redox potential and has attracted much interest in its application for oxidation arsenite (As(III)) species of arsenic to arsenate (As(V)) to decrease arsenic toxicity and promote total arsenic removal. However, coexisting ions such as As(V) and phosphate are ubiquitous and readily bond to manganese oxide surface, consequently passivating surface active sites of manganese oxide and reducing As(III) oxidation. In this study, we present a novel strategy to significantly promote As(III) oxidation activity of OMS-2 by tuning K + concentration in the tunnel. Batch experimental results reveal that increasing K + concentration in the tunnel of OMS-2 not only considerably improved As(III) oxidation kinetics rate from 0.027 to 0.102 min -1 , but also reduced adverse effect of competitive ion on As(III) oxidation. The origin of K + concentration effect on As(III) oxidation was investigated through As(V) and phosphate adsorption kinetics, detection of Mn 2+ release in solution, surface charge characteristics, and density functional theory (DFT) calculations. Experimental results and theoretical calculations confirm that by increasing K + concentration in the OMS-2 tunnel not only does it improve arsenic adsorption on K + doped OMS-2, but also accelerates two electrons transfers from As(III) to each bonded Mn atom on OMS-2 surface, thus considerably improving As(III) oxidation kinetics rate, which is responsible for counteracting the adverse adsorption effects by coexisting ions.

    In this study, the preloading effects of different fractions of wastewater effluent organic matter (EfOM) on the adsorption of trace-level pharmaceutically active compounds (PhACs) onto granular activated carbon (GAC) were investigated. A nanofiltration (NF) membrane was employed to separate the EfOM by size, and two GACs with distinct pore structures were chosen for comparison. The results showed that preloading with EfOM substantially decreased PhAC uptake of the GACs; however, comparable PhAC adsorption capacities were achieved on GACs preloaded by feed EfOM and the NF-permeating EfOM. This indicates that: (1) the NF-rejected, larger EfOM molecules with an expectation to block the PhAC adsorption pores exerted little impact on the adsorbability of PhACs; (2) the smaller EfOM molecules present in the NF permeate contributed mainly to the decrease in PhAC uptake, mostly due to site competition. Of the two examined GACs, the wide pore-size-distributed GAC was found to be more susceptible to EfOM preloading than the microporous GAC. Furthermore, among the fourteen investigated PhACs, the negatively charged hydrophilic PhACs were generally subjected to a greater EfOM preloading impact. Copyright © 2016 Elsevier Ltd.

    The results of reactions between preformed cationic gold oxide clusters and carbon monoxide have been investigated utilizing a fast-flow reactor mass spectrometer. From these studies, it was found that all AunOm+ produced in the cluster source disappeared with CO addition at the reactant gas inlet. Furthermore, with CO addition, intermediate peaks of the form AunOm(CO)x+ (n=1-2, m=0-3, x=0-2) were produced, with some of the species continuing to react at higher CO flows.

  10. Non-Toxic Orbiter Maneuvering System (OMS) and Reaction Control System

    Science.gov (United States)

    Hurlbert, Eric A.; Nicholson, Leonard S. (Technical Monitor)

    1999-01-01

    NASA is pursuing the technology and advanced development of a non-toxic (NT) orbital maneuvering system (OMS) and reaction control system (RCS) for shuttle upgrades, RLV, and reusable first stages. The primary objectives of the shuttle upgrades program are improved safety, improved reliability, reduced operations time and cost, improved performance or capabilities, and commonality with future space exploration needs. Non-Toxic OMS/RCS offers advantages in each of these categories. A non-toxic OMS/RCS eliminates the ground hazards and the flight safety hazards of the toxic and corrosive propellants. The cost savings for ground operations are over $24M per year for 7 flights, and the savings increase with increasing flight rate up to $44M per year. The OMS/RCS serial processing time is reduced from 65 days to 13 days. The payload capability can be increased up to 5100 Ibms. The non-toxic OMS/RCS also provides improved space station reboost capability up to 20 nautical miles over the current toxic system of 14 nautical miles. A NT OMS/RCS represents a clear advancement in the SOA over MMH/NTO. Liquid oxygen and ethanol are clean burning, high-density propellants that provide a high degree of commonality with other spacecraft subsystems including life support, power, and thermal control, and with future human exploration and development of space missions. The simple and reliable pressure-fed design uses sub-cooled liquid oxygen at 250 to 350 psia, which allows a propellant to remain cryogenic for longer periods of time. The key technologies are thermal insulation and conditioning techniques are used to maintain the sub-cooling. Phase I successfully defined the system architecture, designed an integrated OMS/RCS propellant tank, analyzed the feed system, built and tested the 870 lbf RCS thrusters, and tested the 6000 lbf OMS engine. Phase 11 is currently being planned for the development and test of full-scale prototype of the system in 1999 and 2000

    Opsoclonus-myoclonus syndrome (OMS) is a paraneoplastic neurological disorder associated with neuroblastic tumor (NT) in childhood. Half of patients have neurological sequelae after the neurological and oncological treatment. We reviewed the neurological and oncological outcomes of NT with OMS, and discussed whether the treatment of NT would contribute to improving the neurological prognosis. We retrospectively assessed NT patients with OMS from January 2001 to December 2013 at a single institution in Japan. Demographic data, neurological and oncological status, histopathology, treatments, prognosis, and diagnosis and treatment timing were retrospectively reviewed from the records. The timings assessed were the interval between OMS onset and NT detection, initial NT therapy, and initial OMS therapy, the interval between NT therapy and OMS remission, and duration of OMS. A total of 73 patients with NT were treated during the study period, and 5 of 73 patients were diagnosed as having NT with OMS. The median age at onset of OMS was 22 months (range, 18-30 months). The median age at detection of NT was 29 months (range, 21-33 months). Three of five cases showed no uptake on meta-iodobenzylguanidine scintigraphy. The tumor histopathology was neuroblastoma in two patients, ganglioneuroblastoma in two patients, and ganglioneuroma in one patient. Primary resection was performed in three cases. All patients survived. Two of five cases presented with atypical neurological symptoms without opsoclonus. The initial neurological therapy was started within a mean of 20 days (range, 3-76 days) from the onset of OMS in all cases. Four patients received intravenous immunoglobulin, and one with persistent neurological problems received rituximab. Neurological symptoms resolved in three cases. The mean interval between the onset of OMS and the detection of NT in case without neurological sequelae was 57 days (range, 25-113 days), while in case with neurological sequelae it was 365

  3. Membrane Fouling Potential of Secondary Effluent Organic Matter (EfOM) from Conventional Activated Sludge Process

    KAUST Repository

    Wei, Chunhai; Amy, Gary L.

    2012-01-01

    Secondary effluent organic matter (EfOM) from a conventional activated sludge process was filtered through constant-pressure dead-end filtration tests with a sequential ultrafiltration (UF, molecular weight cut-off (MWCO) of 10k Dalton) and nanofiltration (NF, MWCO of 200 Dalton) array to investigate its membrane fouling potential. Advanced analytical methods including liquid chromatography with online carbon detection (LC-OCD) and fluorescent excitation-emission matrix (F-EEM) were employed for EfOM characterization. EfOM consisted of humic substances and building blocks, low molecular weight (LMW) neutrals, biopolymers (mainly proteins) and hydrophobic organics according to the sequence of their organic carbon fractions. The UF rejected only biopolymers and the NF rejected most humics and building blocks and a significant part of LMW neutrals. Simultaneous occurrence of cake layer and standard blocking during the filtration process of both UF and NF was identified according to constant-pressure filtration equations, which was possibly caused by the heterogeneous nature of EfOM with a wide MW distribution (several ten to several million Dalton). Thus the corresponding two fouling indices (kc for cake layer and ks for standard blocking) from UF and NF could characterize the fouling potential of macromolecular biopolymers and low to intermediate MW organics (including humics, building blocks, LMW neutrals), respectively. Compared with macromolecular biopolymers, low to intermediate MW organics exhibited a much higher fouling potential due to their lower molecular weight and higher concentration.

    2011-01-01

    Solid-phase photocatalytic degradation of polyethylene (PE) film with cryptomelane-type manganese oxide (OMS-2) as photocatalyst was investigated in the ambient air under ultraviolet and visible light irradiation. The properties of the composite films were compared with those of the pure PE film through performing weight loss monitoring, IR spectroscopy, scanning electron microscopic (SEM) and X-ray photoelectron spectroscopy (XPS). The photoinduced degradation of PE-OMS-2 composite films was higher than that of the pure films, while there has been little change under the visible light irradiation. The weight loss of PE-OMS-2 (1.0 wt%) composite films steadily decreased and reached 16.5% in 288 h under UV light irradiation. Through SEM observation there were some cavities on the surface of composite films, but few change except some surface chalking phenomenon occurred in pure PE film. The degradation rate with ultraviolet irradiation is controllable by adjusting the content of OMS-2 particles in PE plastic. Finally, the mechanism of photocatalytic degradation of the composite films was briefly discussed.

    Wilde, E.W.

    2003-01-01

    Groundwater in D-Area at the Savannah River Site (SRS) is contaminated with trichloroethylene (TCE) and by-products resulting FR-om discharges of this organic solvent during past disposal practices. This contaminated groundwater occurs primarily at depths of 9 meters to 15 meters below ground surface, well below the depths that are typically penetrated by plant roots. The process investigated in this study involved pumping water FR-om the contaminated aquifer and discharging the water into overlying test plots two inches below the surface using drip irrigation. The field treatability study was conducted FR-om 8/31/00 to 4/18/02 using six 0.08 hectare test plots, two each containing pines, cottonwoods, and no vegetation (controls). The primary objective was to determine the overall effectiveness of the process for TCE removal and to determine the principal biotic and abiotic pathways for its removal. Results demonstrated that the process provides a viable method to remove TCE-contaminated groundwater. The data clearly showed that the presence of trees reduced volatilization of TCE FR-om the drip irrigation system to the atmosphere. Influent groundwater TCE concentrations averaging 89 mg/L were reduced to non-detectable levels (less than 5 mg/L) within the upper two feet of soil (rhizosphere)

Ces données expérimentales et cliniques fournissent une base biologique à la relation observée entre un apport augmenté de poisson ou d’oméga 3 et un risque abaissé de mort subite dans plusieurs études de cohortes.

  7. OM and A considerations in PLEx decision making for CANDUR reactors

    2002-01-01

    In recent years, owners and operators of mature nuclear plants that are reaching their design life, are contemplating Plant Life Extension (PLEx) to continue generating low cost electricity. While the business case for PLEx is typically organized along the immediate investment requirements to carryout the planned refurbishment of the plant components, a similar level of attention and focus should be placed on the post refurbishment OM and A costs of the plant. If the refurbishment is based on a one-to-one replacement of aging or non-repairable components, then post refurbishment OM and A costs can be expected to be similar to those before refurbishment. This paper presents supporting arguments to align post-refurbishment OM and A, with certain modifications to the plant during refurbishment, which can yield a significantly reduced OM and A costs over the extended life. The paper describes techniques, which are being investigated for operating CANDU R plants, the will reduce the overall manpower requirements through more automation applied to testing, analyses, equipment status monitoring, regulatory surveillance/reporting etc., and integration of plant information systems. Application of Condition Based Monitoring combined with Reliability Centred Maintenance will minimize operational maintenance intervention and action, and hence, further reduce the maintenance manpower resources. These examples will be applied to two typical CANDU R situations - one using PLEx as the example (Point Lepreau Station) and the other using plant restart of laid up units (Pickering A Station) to illustrate these concepts. Specific data for these two plant types will be described with and without implementation of the OM and A reduction techniques described above to demonstrate potential manpower reductions. The paper will also describe how the Canadian nuclear industry has been able to deal with the lack of trained personnel and turn things around; and is in a position to start up the

  9. Ferrihydrite-associated organic matter (OM) stimulates reduction by Shewanella oneidensis MR-1 and a complex microbial consortia

    The formation of Fe(III) oxides in natural environments occurs in the presence of natural organic matter (OM), resulting in the formation of OM-mineral complexes that form through adsorption or coprecipitation processes. Thus, microbial Fe(III) reduction in natural environments most often occurs in the presence of OM-mineral complexes rather than pure Fe(III) minerals. This study investigated to what extent does the content of adsorbed or coprecipitated OM on ferrihydrite influence the rate of Fe(III) reduction by Shewanella oneidensis MR-1, a model Fe(III)-reducing microorganism, in comparison to a microbial consortium extracted from the acidic, Fe-rich Schlöppnerbrunnen fen. We found that increased OM content led to increased rates of microbial Fe(III) reduction by S. oneidensis MR-1 in contrast to earlier findings with the model organism Geobacter bremensis. Ferrihydrite-OM coprecipitates were reduced slightly faster than ferrihydrites with adsorbed OM. Surprisingly, the complex microbial consortia stimulated by a mixture of electrons donors (lactate, acetate, and glucose) mimics S. oneidensis under the same experimental Fe(III)-reducing conditions suggesting similar mechanisms of electron transfer whether or not the OM is adsorbed or coprecipitated to the mineral surfaces. We also followed potential shifts of the microbial community during the incubation via 16S rRNA gene sequence analyses to determine variations due to the presence of adsorbed or coprecipitated OM-ferrihydrite complexes in contrast to pure ferrihydrite. Community profile analyses showed no enrichment of typical model Fe(III)-reducing bacteria, such as Shewanella or Geobacter sp., but an enrichment of fermenters (e.g., Enterobacteria) during pure ferrihydrite incubations which are known to use Fe(III) as an electron sink. Instead, OM-mineral complexes favored the enrichment of microbes including Desulfobacteria and Pelosinus sp., both of which can utilize lactate and acetate as an electron

    2007-01-01

    Advances in tumor immunology are supporting the clinical implementation of several immunological approaches to cancer in the clinical setting. However, the alternate success of current immunotherapeutic regimens underscores the fact that the molecular mechanisms underlying immune-mediated tumor rejection are still poorly understood. Given the complexity of the immune system network and the multidimensionality of tumor/host interactions, the comprehension of tumor immunology might greatly benefit from high-throughput microarray analysis, which can portrait the molecular kinetics of immune response on a genome-wide scale, thus accelerating the discovery pace and ultimately catalyzing the development of new hypotheses in cell biology. Although in its infancy, the implementation of microarray technology in tumor immunology studies has already provided investigators with novel data and intriguing new hypotheses on the molecular cascade leading to an effective immune response against cancer. Although the general principles of microarray-based gene profiling have rapidly spread in the scientific community, the need for mastering this technique to produce meaningful data and correctly interpret the enormous output of information generated by this technology is critical and represents a tremendous challenge for investigators, as outlined in the first section of this book. In the present Chapter, we report on some of the most significant results obtained with the application of DNA microarray in this oncology field.

    2010-01-15

    Separation of carbon dioxide (CO(2)) from gaseous mixture is an important issue for the removal of CO(2) in natural gas processing and power plants. The ordered mesoporous silicas (OMS) with uniform pore structure and high density of silanol groups, have attracted the interest of researchers for separation of carbon dioxide (CO(2)) using adsorption process. These mesoporous silicas after functionalization with amino groups have been studied for the removal of CO(2). The potential of functionalized ordered mesoporous silica membrane for separation of CO(2) is also recognized. The present paper reviews the synthesis of mesoporous silicas and important issues related to the development of mesoporous silicas. Recent studies on the CO(2) separation using ordered mesoporous silicas (OMS) as adsorbent and membrane are highlighted. The future prospectives of mesoporous silica membrane for CO(2) adsorption and separation are also presented and discussed. Copyright 2009 Elsevier B.V. All rights reserved.

    The clinical benefits of memantine, depending on the baseline cognitive and affective conditions in real world dementia clinics, have not been completely examined. We performed the "Okayama Memantine Study II (OMS II)" to retrospectively evaluate the clinical effects of memantine monotherapy (n = 38) in Alzheimer's disease (AD) patients using seven batteries to assess dementia at the baseline, at 3, 6, and 12 months. Additionally, we divided 163 AD patients treated with memantine into two subgroups depending on the baseline cognitive score of the Mini-Mental State Examination (MMSE): the MMSE OMS II showed that memantine monotherapy improved BPSD until 12 months. The higher baseline cognitive subgroup (MMSE ≥15) and the worse baseline BPSD subgroup were expected to show better effects with memantine.

  6. O/M ratio measurement in pure and mixed oxide fuels - where are we now?

    2001-07-01

    The scale-down in the US and Russian nuclear weapons stockpiles has produced a surplus of weapons grade plutonium and highly enriched uranium. The incorporation into mixed-oxide fuel (MOX) is one of the currently favored routes for surplus weapons-grade plutonium. The use of MOX as a nuclear reactor fuel is well established, particularly in Europe and Japan but not in the US. The primary purpose of this investigation was to evaluate existing analytical techniques for their applicability to O/M (oxygen-to-metal ratio) measurements of MOX derived from excess weapons plutonium. The second objective of this investigation was to bring up-to-date the literature on O/M measurement methods, which has not been undertaken in over 20 years. There are several classification schemes that can be used to organize O/M measurement methods. The most popular schemes are based on (a) whether the analysis is performed in solution (wet chemical) or on solid material (dry), and (b) whether the concentration of major constituents are analyzed directly (direct) or are inferred (indirect). Solid state coulometric titration is currently used extensively in studies of phase equilibria, defect chemistry, thermochemical measurement of oxides, including ferrites. Regardless of which indirect method is used (solid state coulometric titration or thermogravimetry), a primary, direct method will also be required for the establishment of the MO{sub 2} reference state, determination of method bias, and periodic calibration. It was recommended that the following direct method be adapted for this purpose: oxygen measurement by inert gas fusion/carbon reduction, and total U, Pu by controlled potential coulometry. In a table are listed the experimental values of accuracy for about 30 O/M methods. (A.C.)

    Non-destructive methods such as diffuse reflectance infrared Fourier transform spectroscopy (DRIFT) have been applied to characterize organic matter (OM) at intact structural surfaces among others. However, it is often difficult to distinguish effects of organic components on DRIFT signal intensities from those of mineral components. The objective of this study was to re-evaluate DRIFT spectra from intact earthworm burrow walls and coated cracks to improve the interpretation of C-H and C=O bands. We compared DRIFT and transmission Fourier transform infrared (FTIR) spectra of entire samples that were from the same pedogenetic soil horizon, but different in mineral composition and texture (i.e., glacial till versus loess). Spectra of incinerated samples were subtracted from the original spectra. Transmission FTIR and DRIFT spectra were almost identical for entire soil samples. However, the DRIFT spectra were affected by the bulk mode bands (i.e., wavenumbers 2000 to 1700 cm-1) that affected spectral resolution and reproducibility. The ratios between C-H and C=O band intensities as indicator for OM quality obtained with DRIFT were smaller than those obtained from transmission FTIR. A spectral subtraction procedure was found to reduce effects of mineral absorption bands on DRIFT spectra allowing an improved interpretation. DRIFT spectroscopy as a non-destructive method for analyzing OM composition at intact surfaces in structured soils could be calibrated with information obtained with the more detailed transmission FTIR and complementary methods.

    Highlights: ► The influence of high temperature exposure on OM4 fibers’ mechanical properties. ► Researching OM4 class fibers for use in innovative Optical Multi Chip Module. ► The influence of bending at a very small radius, up to 2 mm, on MM fibers. - Abstract: For future generations of electronic systems, a severe bottleneck is expected on the interconnection level and the use of optical interconnection is considered as one of the most promising solutions in this matter. Recent progress in fiber development resulted in new generation of optical fibers that are bend insensitive. This makes them ideal for Multi Chip Module (MCM) application. This paper focuses on OM4 bend insensitive multi-mode fibers’ usefulness for MCM integration, particularly the investigation of MM fiber loss is presented, which is influenced by bend diameter and the fiber's mechanical performance under influence of high temperature (400 °C–1000 °C adequate to MCM production process).

    Measurements of artificial plasma turbulence were obtained during two Shuttle Exhaust Ionospheric Turbulence Experiments (SEITE) conducted during the flights of the Space Shuttle (STS-127 and STS-129). Based on computer modeling at the NRL PPD and Laboratory for Computational Physics & Fluid Dynamics (LCP), two dedicated burns of the Space Shuttle Orbital Maneuver Subsystem (OMS) engines were scheduled to produce 200 to 240 kg exhaust clouds that passed over the Air Force Research Laboratory (AFRL) Communications, Navigation, and Outage Forecast System (C/NOFS) satellite. This operation required the coordination by the DoD Space Test Program (STP), the NASA Flight Dynamics Officer (FDO), the C/NOFS payload operations, and the C/NOFS instrument principal investigators. The first SEITE mission used exhaust from a 12 Second OMS burn to deposit 1 Giga-Joules of energy into the upper atmosphere at a range of 230 km from C/NOFS. The burn was timed so C/NOFS could fly though the center of the exhaust cloud at a range of 87 km above the orbit of the Space Shuttle. The first SEITE experiment is important because is provided plume detection by ionospheric plasma and electric field probes for direct sampling of irregularities that can scatter radar signals. Three types of waves were detected by C/NOFS during and after the first SEITE burn. With the ignition and termination of the pair of OMS engines, whistler mode signals were recorded at C/NOFS. Six seconds after ignition, a large amplitude electromagnetic pulse reached the satellite. This has been identified as a fast magnetosonic wave propagating across magnetic field lines to reach the electric field (VEFI) sensors on the satellite. Thirty seconds after the burn, the exhaust cloud reach C/NOFS and engulfed the satellite providing very strong electric field turbulence along with enhancements in electron and ion densities. Kinetic modeling has been used to track the electric field turbulence to an unstable velocity

  1. Effects of precursor and sulfation on OMS-2 catalyst for oxidation of ethanol and acetaldehyde at low temperatures.

    Volatile organic compounds (VOCs) emitted from many industrial processes and transportation activities are major organic pollutants in the atmosphere and toxic to human health. Octahedral molecular sieve (OMS-2) catalysts with different precursors and sulfate-acidified OMS-2 catalysts were synthesized using refluxing methods. The catalysts were investigated on complete oxidation of ethanol and acetaldehyde, and both demonstrated good reactivity. However, acidification resulted in a decrease in activity. OMS-2 catalyst using MnSO(4) as precursor exhibited the best catalytic performance and, thus, was selected for catalyst deactivation by sulfur dioxide. The results of this study suggested that the Mn-O bond of OMS-2 catalysts was the main determinant of the catalytic activity toward oxygenated VOC oxidation and weaker acid sites benefited higher acetaldehyde selectivity. Catalyst deactivation resulted from a strong but slow chemical interaction between the Mn-O bond and sulfur dioxide, probably forming manganese sulfate.

    In this study, CN-TiO₂ was modified with cryptomelane octahedral molecular sieves (OMS-2) by the sol-gel method based on the self-assembly technique to enhance its photocatalytic activity under the daylight irradiation. The synthesized samples were characterized by X-ray diffraction (XRD), UV-vis spectroscopy, Fourier transform infrared spectroscopy (FT-IR) and porosimeter analysis. The results showed that the addition of OMS-2 in the sol lead to higher Brunauer-Emmett-Teller (BET) surface area, pore volume, porosity of particle after heat treatment and the specific surface area, porosity, crystallite size and pore size distribution could be controlled by adjusting the calcination temperature. Compared to the CN-TiO₂-400 sample, CN-TiO₂/OMS-2-400 exhibited greater red shift in absorption edge of samples in visible region due to the OMS-2 coated. The enhancement of photocatalytic activity of CN-TiO₂/OMS-2 composite photocatalyst was subsequently evaluated for the degradation of the methyl orange dye under the daylight irradiation in water. The results showed that the methyl orange dye degradation rate reach to 37.8% for the CN-TiO₂/OMS-2-400 sample under the daylight irradiation for 5 h, which was higher than that of reference sample. The enhancement in daylight photocatalytic activities of the CN-TiO₂/OMS samples could be attributed to the synergistic effects of OMS-2 coated, larger surface area and red shift in adsorption edge of the prepared sample.

    Peptidoglycan recognition proteins (PGRPs), a group of pattern recognition receptors (PRRs), are innate immune molecules that are structurally conserved through evolution in both invertebrate and vertebrate animals. In teleost fish, several PGRPs have been characterized recently. They have both amidase activity and bactericidal activity and are involved in indirectly killing bacteria and regulating multiple signaling pathways. However, the knowledge of functional similarity and divergence between PGRP paralogs for their role as an immune modulator in teleost fish is still limited. In this study, we identified a novel PGRP paralog, termed OmPGRP-L2 from the rainbow trout (Oncorhynchus mykiss). OmPGRP-L2 contains the conserved PGRP domain and the four Zn 2+ -binding amino acid residues required for amidase activity. Quantitative RT-PCR analysis indicated that OmPGRP-L2 is highly expressed in liver. Overexpression of OmPGRP-L2 in a rainbow trout hepatocyte cell line RTH-149 challenged with Edwardsiella tarda resulted in down-regulation of IL-1β and TNF-α expression. When overexpressed in RTH-149 cells, OmPGRP-L2 inhibited NF-κB activity with or without bacterial stimulation. Collectively, these findings suggest that OmPGRP-L2 has an immunomodulatory function, via NF-κB inhibition in liver. Copyright © 2017 Elsevier B.V. All rights reserved.

    Clinical trials are evaluating new combinations of drugs with the goal of diminishing the toxicity associated with the current regimens while not compromising the chance for cure. The evolution of information and staging studies such as tumor markers, CT scanning and MR scanning has made possible the detection of residual metastatic disease while obviating the need for surgical staging procedures. This has made less treatment possible for a large number of patients. The regularity of follow-up studies has made early detection of recurrences a possibility, so that effective and curative treatment is generally possible

    In this paper, we analyze the cosmological models in Einstein-Aether gravity, which is a modified theory of gravity in which a time-like vector field breaks the Lorentz symmetry. We use this formalism to analyse different cosmological models with different behavior of the scale factor. In this analysis, we use a certain functional dependence of the Dark Energy (DE) on the Hubble parameter H . It will be demonstrated that the Aether vector field has a non-trivial effect on these cosmological models. We also perform the Om diagnostic in Einstein-Aether gravity and we fit the parameters of the cosmological models using recent observational data.

    Curtis, Leslie A.; Hurlbert, Eric A.

    1999-01-01

    NASA is pursuing non-toxic propellant technologies applicable to RLV and Space Shuttle orbital maneuvering system (OMS) and reaction control system (RCS). The primary objectives of making advancements in an OMS/RCS system are improved safety, reliability, and reduced operations and maintenance cost, while meeting basic operational and performance requirements. An OMS/RCS has a high degree of direct interaction with the vehicle and crew and requires subsystem and components that are compatible with integration into the vehicle with regard to external mold-line, power, and thermal control. In July 1997, a Phase I effort for the technology and advanced development of an upgrade of the space shuttle was conducted to define the system architecture, propellant tank, feed system, RCS thrusters, and OMS engine. Phase I of the project ran from July 1997 to October 1998. Phase II is currently being planned for the development and test of full-scale prototype of the system in 1999 and 2000. The choice of pressure-fed liquid oxygen (LO2) and ethanol is the result of numerous trade studies conducted from 1980 to 1996. Liquid oxygen and ethanol are clean burning, high-density propellants that provide a high degree of commonality with other spacecraft subsystems including life support, power, and thermal control, and with future human exploration and development of space missions. The key to this pressure-fed system is the use of subcooled liquid oxygen at 350 psia. In this approach, there is 80 degrees R of subcooling, which means that boil-off will not occur until the temperature has risen 80 R. The sub-cooling results naturally from loading propellants at 163 R, which is the saturation temperature at 14.7 psia, and then pressurizing to 350 psia on the launch pad. Thermal insulation and conditioning techniques are then used to limit the LO2 temperature to 185 R maximum, and maintain the sub-cooling. The other key is the wide temperature range of ethanol, -173 F to +300 F, which

    2016-02-01

    The state of the art in biodiversity data management unfortunately encompases a plethora of diverse data formats. Compared to other research fields, there is a lack in harmonization and standardization of these data. While data from traditional biodiversity collections (e.g. from museums) can be easily represented by existing standard as provided by TDWG, the growing number of field observations stemming from both VGI activities (e.g. iNaturalist) as well as from automated systems (e.g. animal biotelemetry) would at the very least require upgrades of current formats. Moreover, from an eco-informatics perspective, the integration and use of data from different scientific fields is the norm (abiotic data, geographic information, etc.); the possibility to represent this information and biodiversity data in a homogeneous way would be an advantage for interoperability, allowing for easy integration across environmental media. We will discuss the possibility to exploit the Open Geospatial Consortium/ISO standard, Observations and Measurements (O&M) [1], a generic conceptual model developed for observation data but with strong analogies with the biodiversity-oriented OBOE ontology [2]. The applicability of OGC O&M for the provision of biodiviersity occurence data has been suggested by the INSPIRE Cross Thematic Working Group on Observations & Measurements [3], Inspire Environmental Monitoring Facilities Thematic Working Group [4] and New Zealand Environmental Information Interoperability Framework [5]. This approach, in our opinion, could be an advantage for the biodiversity community. We will provide some examples for encoding biodiversity occurence data using the O&M standard in addition to highlighting the advatages offered by O&M in comparison to other representation formats.

  4. Code cases for implementing risk-based inservice testing in the ASME OM code

    Energy Technology Data Exchange (ETDEWEB)

    Rowley, C.W.

    1996-12-01

    Historically inservice testing has been reasonably effective, but quite costly. Recent applications of plant PRAs to the scope of the IST program have demonstrated that of the 30 pumps and 500 valves in the typical plant IST program, less than half of the pumps and ten percent of the valves are risk significant. The way the ASME plans to tackle this overly-conservative scope for IST components is to use the PRA and plant expert panels to create a two tier IST component categorization scheme. The PRA provides the quantitative risk information and the plant expert panel blends the quantitative and deterministic information to place the IST component into one of two categories: More Safety Significant Component (MSSC) or Less Safety Significant Component (LSSC). With all the pumps and valves in the IST program placed in MSSC or LSSC categories, two different testing strategies will be applied. The testing strategies will be unique for the type of component, such as centrifugal pump, positive displacement pump, MOV, AOV, SOV, SRV, PORV, HOV, CV, and MV. A series of OM Code Cases are being developed to capture this process for a plant to use. One Code Case will be for Component Importance Ranking. The remaining Code Cases will develop the MSSC and LSSC testing strategy for type of component. These Code Cases are planned for publication in early 1997. Later, after some industry application of the Code Cases, the alternative Code Case requirements will gravitate to the ASME OM Code as appendices.

  6. The behaviour of zirconium alloys in Santowax OM organic coolant at high temperatures

    1964-10-01

    Zirconium alloys have been exposed to Santowax OM at temperatures of 320 to 400 o C for times as long as 5000 hours. Short-term experiments (less than 2 weeks) were done in stainless-steel bombs and small out-of-pile loops. The X-7 organic loop in the NRX reactor was used to study long-term oxidation and hydriding both in-flux and out-of-flux. The results obtained lead to several tentative conclusions: Aluminum cladding serves as an effective hydrogen barrier; Considerable protection against hydriding is given by zirconium oxide, provided impurities in the organic are carefully controlled; Hydriding is greatly enhanced by the presence of chlorine in the coolant; and, Hydriding is somewhat enhanced by neutron irradiation. Of considerable significance is the fact that a Zircaloy-4 in-reactor test section of the X-7 loop was exposed to Santowax OM at 320 to 400 o C for more than 5000 hours without excessive hydriding.

  8. Code cases for implementing risk-based inservice testing in the ASME OM code

    International Nuclear Information System (INIS)

    Rowley, C.W.

    1996-01-01

    Historically inservice testing has been reasonably effective, but quite costly. Recent applications of plant PRAs to the scope of the IST program have demonstrated that of the 30 pumps and 500 valves in the typical plant IST program, less than half of the pumps and ten percent of the valves are risk significant. The way the ASME plans to tackle this overly-conservative scope for IST components is to use the PRA and plant expert panels to create a two tier IST component categorization scheme. The PRA provides the quantitative risk information and the plant expert panel blends the quantitative and deterministic information to place the IST component into one of two categories: More Safety Significant Component (MSSC) or Less Safety Significant Component (LSSC). With all the pumps and valves in the IST program placed in MSSC or LSSC categories, two different testing strategies will be applied. The testing strategies will be unique for the type of component, such as centrifugal pump, positive displacement pump, MOV, AOV, SOV, SRV, PORV, HOV, CV, and MV. A series of OM Code Cases are being developed to capture this process for a plant to use. One Code Case will be for Component Importance Ranking. The remaining Code Cases will develop the MSSC and LSSC testing strategy for type of component. These Code Cases are planned for publication in early 1997. Later, after some industry application of the Code Cases, the alternative Code Case requirements will gravitate to the ASME OM Code as appendices

    In order to determine the dose responsiveness to radiation of ocular melanoma, we conducted an in vitro dose-response study on a monolayer cell culture using a clonogenic assay. The effects on cell survival were determined relative to unirradiated controls. A human epithelioid ocular melanoma cell line, OM431, was maintained in tissue culture and serial dilutions of viable cells were plated in flasks, allowed to settle and attach for 48 h, and subsequently irradiated with 1-10 Gy in single fractions. After 2 weeks, the number of reproducing clones (forming colonies with greater than 32 cells or five generations) were counted. The surviving fractions of cells were plotted on a cell survival curve using the linear quadratic model. The survival curve showed a large initial shoulder followed by an exponential decline in growth. Our data suggest that the OM431 ocular melanoma cell line responds to irradiation in a manner similar to other melanoma cell lines and is relatively radioresistent especially at lower doses.

  11. Description of comprehensive pump test change to ASME OM code, subsection ISTB

    International Nuclear Information System (INIS)

    Hartley, R.S.

    1994-01-01

    The American Society of Mechanical Engineers (ASME) Operations and Maintenance (OM) Main Committee and Board on Nuclear Codes and Standards (BNCS) recently approved changes to ASME OM Code-1990, Subsection ISTB, Inservice Testing of Pumps in Light-Water Reactor Power Plants. The changes will be included in the 1994 addenda to ISTB. The changes, designated as the comprehensive pump test, incorporate a new, improved philosophy for testing safety-related pumps in nuclear power plants. An important philosophical difference between the open-quotes old codeclose quotes inservice testing (IST) requirements and these changes is that the changes concentrate on less frequent, more meaningful testing while minimizing damaging and uninformative low-flow testing. The comprehensive pump test change establishes a more involved biannual test for all pumps and significantly reduces the rigor of the quarterly test for standby pumps. The increased rigor and cost of the biannual comprehensive tests are offset by the reduced cost of testing and potential damage to the standby pumps, which comprise a large portion of the safety-related pumps at most plants. This paper provides background on the pump testing requirements, discusses potential industry benefits of the change, describes the development of the comprehensive pump test, and gives examples and reasons for many of the specific changes. This paper also describes additional changes to ISTB that will be included in the 1994 addenda that are associated with, but not part of, the comprehensive pump test

Nous posons tout d’abord le problème de la représentation de la connaissance lexicale, en expliquant l’importance d’adopter une métaphore géométrique du lexique qui soit adaptée à l’étude lexicologique et à ses diverses applications. Cela nous amène préciser la nature même du lexique qui doit faire l’objet d’une telle géométrisation en revenant sur la notion souvent galvaudée de lexique mental et en distinguant deux types de lexiques mentaux – le lexique logique et le lexique physiologique –, dont seul le premier est notre objet d’étude. Après avoir examiné les principales métaphores courantes du lexique logique, nous présentons un modèle formel plausible, sur lequel s’appuie notamment le projet du Réseau Lexical du Français : il s’agit des Systèmes Lexicaux, dont la charpente structurale est constituée par les fonctions lexicales Sens-Texte.

  13. Ferrihydrite-associated organic matter (OM stimulates reduction by Shewanella oneidensis MR-1 and a complex microbial consortia

    Directory of Open Access Journals (Sweden)

    2017-11-01

    Full Text Available The formation of Fe(III oxides in natural environments occurs in the presence of natural organic matter (OM, resulting in the formation of OM–mineral complexes that form through adsorption or coprecipitation processes. Thus, microbial Fe(III reduction in natural environments most often occurs in the presence of OM–mineral complexes rather than pure Fe(III minerals. This study investigated to what extent does the content of adsorbed or coprecipitated OM on ferrihydrite influence the rate of Fe(III reduction by Shewanella oneidensis MR-1, a model Fe(III-reducing microorganism, in comparison to a microbial consortium extracted from the acidic, Fe-rich Schlöppnerbrunnen fen. We found that increased OM content led to increased rates of microbial Fe(III reduction by S. oneidensis MR-1 in contrast to earlier findings with the model organism Geobacter bremensis. Ferrihydrite–OM coprecipitates were reduced slightly faster than ferrihydrites with adsorbed OM. Surprisingly, the complex microbial consortia stimulated by a mixture of electrons donors (lactate, acetate, and glucose mimics S. oneidensis under the same experimental Fe(III-reducing conditions suggesting similar mechanisms of electron transfer whether or not the OM is adsorbed or coprecipitated to the mineral surfaces. We also followed potential shifts of the microbial community during the incubation via 16S rRNA gene sequence analyses to determine variations due to the presence of adsorbed or coprecipitated OM–ferrihydrite complexes in contrast to pure ferrihydrite. Community profile analyses showed no enrichment of typical model Fe(III-reducing bacteria, such as Shewanella or Geobacter sp., but an enrichment of fermenters (e.g., Enterobacteria during pure ferrihydrite incubations which are known to use Fe(III as an electron sink. Instead, OM–mineral complexes favored the enrichment of microbes including Desulfobacteria and Pelosinus sp., both of which can utilize lactate and

Med udgangs-punkt i en undersøgelse fortaget i forbindelse med forfatterens ph.d.- projekt (afsluttet i sommeren 2014 vil artiklen på baggrund af en verserende debat om masteruddannelsernes kvalitet og relevans diskutere kvalitet i dansk akademisk videreuddannelse. Den kvalitative undersøgelse, der ligger til grund for artiklen, anskueliggør, at selvom de studerende oplever, at de gennem deres toårige studie har tilegnet sig en række konkrete og brugbare kompetencer, peger de på andre og mere transformative læringskvaliteter, når man beder dem om at beskrive det vigtigste udkomme af deres uddannelsesforløb. Artiklen argumenterer for, at denne læring, der i højere grad kan siges at knytte sig til personen i form af en etisk-eksistentiel dannelse frem for en specifik kunnen, har nær sammenhæng med det at befinde sig i et akademisk, videnskabeligt miljø. På dette grundlag søger artiklen at problematisere aktuelle forslag om at slække på kravet til masteruddannelsernes videnskabelige fundament for i stedet at fokusere på mere instrumentelle, erhvervsrettede kompetencer og færdigheder.

I ett dialogiskt perspektiv (Linell, 2011 undersöks interaktionella mönster avseende dominans, dynamik och koherens i tre svensklärargruppers bedömningssamtal. Dessa interaktionella mönster ställs i relation till uttryck för samstämmighet inom och mellan lärargrupperna. Resultatet visar att lärarna uttrycker hög grad av samstämmighet i bedömningssamtalen men att de bedömningar som lärarna gör enskilt i anslutning till samtalen enbart till viss del överensstämmer med gruppens beslut. Lägst grad av samstämmighet uppvisar den lärargrupp som i samtalen framstod som mest samstämmig. Där kännetecknas beslutsprocesserna av låg intensitet genom att få alternativ till bedömningar prövas. I de lärargrupper där intensiteten är högre genom att flera lärare styr samtalet i olika riktningar och där lärarna tillsammans prövar flera olika förslag på bedömning överensstämmer även enskilda lärares bedömningar i högre grad med gruppens beslut. Bedömningsöverensstämmelsen mellan lärargrupperna är däremot låg.

    The potential and mechanism of synthesized magnetic octahedral molecular sieve (Fe 3 O 4 @OMS-2) nanoparticles in enhancing the aerobic microbial ability of sequencing batch reactor (SBR) for treating dye wastewater have been revealed in this study. The addition of Fe 3 O 4 @OMS-2 of 0.25g/L enhanced the decolorization of SBRs with an operation cycle of 24h by more than 20%. The 16S rRNA gene high-throughput sequencing indicated Fe 3 O 4 @OMS-2 increased the microbial richness and diversity of SBRs, and more importantly, promoted the potential dye-degrading bacteria. After a series of enriching and screening, four bacterial strains with the considerable decolorizing ability were isolated from SBRs, designating Alcaligenes faecalis FP-G1, Bacillus aryabhattai FP-F1, Escherichia fergusonii FP-D1 and Rhodococcus ruber FP-E1, respectively. The growth and decolorization of these pure strains were promoted in the presence of Fe 3 O 4 @OMS-2, which agrees with the result of high-throughput sequencing. Monitoring dissolved Fe/Mn ions and investigating the change of oxidation states of Fe/Mn species discovered OMS-2 composition played the critical role in modulating the microbial community. The significant enhancement of Mn-oxidizing/-reducing bacteria suggested microbial Mn redox may be the key action mechanism of Fe 3 O 4 @OMS-2, which can provide numerous benefits for the microbial community and decolorization of SBRs.

    Ocular motor score (OMS) is a new clinical test protocol for evaluating ocular motor functions in children and young adults. OMS is a set of 15 important and relevant non-invasive ocular motor function parameters derived from clinical practice. The aim of the study was to evaluate OMS according to intrarater and inter-rater agreement. Forty children aged 4-10 years, 23 girls median age 6.5 (range 4.3-9.3) and 17 boys median age 5.8 (range 4.1-9.8) were included. The ocular motor functions were assessed and scored according to the OMS protocol. The examinations were videotaped. To obtain the intrarater agreement, the first author examined and scored the children twice, first in the clinic and 2 weeks later by watching the videotape. To obtain the inter-rater agreement, three other raters independently scored the ocular motor function of the children by watching the videotapes. The overall observed intrarater agreement was 88%, and the observed inter-rater agreement between the three raters was 80%. For none of the subtests was there an observed intrarater agreement lower than 65%. Three of the subtests had an observed inter-rater agreement of 65% or below. Overall there was high observed intra- and inter-rater agreement for the OMS test protocol. Subtests such as saccades and smooth pursuit were more difficult for raters to score similarly according the clinical OMS test protocol. © 2015 Acta Ophthalmologica Scandinavica Foundation.

  8. Obesity-resistant S5B rats showed great cocaine conditioned place preference than the obesity-prone OM rats

    Dopamine (DA) and the DA D2 receptor (D2R) are involved in the rewarding and conditioned responses to food and drug rewards. Osborne-Mendel (OM) rats are genetically prone and S5B/P rats are genetically resistant to obesity when fed a high-fat diet. We hypothesized that the differential sensitivity of these two rat strains to natural rewards may also be reflected in sensitivity to drugs of abuse. Therefore, we tested whether OM and S5B/P rats showed a differential preference to cocaine using conditioned place preference (CPP). To also evaluate whether there is specific involvement of the D2R in this differential conditioning sensitivity, we then tested whether the D2R agonist bromocriptine (BC) would differentially affect the effects of cocaine in the two strains. OM and S5B/P rats were conditioned with cocaine (5 or 10 mg/kg) in one chamber and saline in another for 8 days. Rats were then tested for cocaine preference. The effects of BC (0.5, 1, 5, 10, 20 mg/kg) on cocaine preference were then assessed in subsequent test sessions. OM rats did not show a significant preference for the cocaine-paired chamber on test day. Only the S5B/P rats showed cocaine CPP. Later treatment with only the highest dose of BC resulted in reduced cocaine CPP in S5B/P rats when treated with 5 mg/kg cocaine and in OM rats treated with 10 mg/kg cocaine. Our results indicated that obesity-resistant S5B rats showed greater cocaine CPP than the obesity-prone OM rats. These findings do not support a theory of common vulnerability for reinforcer preferences (food and cocaine). However, they show that BC reduced cocaine conditioning effects supporting at least a partial regulatory role of D2R in conditioned responses to drugs.

    A new case of peripheral epithelial odontogenic tumor (Pindborg tumor) is reported. It is localized in the superior right gingival region, a less frequent site, and has the histopathological features previously reported. Immunochemical studies were performed, revealing a differential positive stain to cytokeratins in tumor cells deeply seated in the tumor mass, probably related to tumoral cell heterogeneity.Interestingly, in this particular case S-100 protein positive reactivity was also detected in arborescent cells intermingled with tumoral cells, resembling Langerhans cells. Even though referred in the literature in central Pindborg tumors, no references were found about their presence in peripheral tumors, like the one that is presented here

    The nanostructured Ce ion substituted cryptomelane-type octahedral molecular sieve (OMS-2) catalyst exhibits strong absorption in the entire solar spectrum region. The Ce ion substituted OMS-2 catalyst can efficiently transform the absorbed solar energy to thermal energy, resulting in a considerable increase of temperature. By combining the efficient photothermal conversion and thermocatalytic activity of the Ce ion substituted OMS-2 catalyst, we carried out full solar spectrum, visible-infrared, and infrared light driven catalysis with extremely high efficiency. Under the irradiation of full solar spectrum, visible-infrared, and infrared light, the Ce ion substituted OMS-2 catalyst exhibits extremely high catalytic activity and excellent durability for the oxidation of volatile organic pollutants such as benzene, toluene, and acetone. Based on the experimental evidence, we propose a novel mechanism of solar light driven thermocatalysis for the Ce ion substituted OMS-2 catalyst. The reason why the Ce ion substituted OMS-2 catalyst exhibits much higher catalytic activity than pure OMS-2 and CeO2/OMS-2 nano composite under the full solar spectrum irradiation is discussed.The nanostructured Ce ion substituted cryptomelane-type octahedral molecular sieve (OMS-2) catalyst exhibits strong absorption in the entire solar spectrum region.

    The cryptomelane-type manganese oxide octahedral molecular sieve (OMS-2)-supported Pd (0.5 wt% Pd/OMS-2-DP, 0.5 wt% Pd/OMS-2-PI, and 0.5 wt% Pd/OMS-2-EX) catalysts were prepared by the deposition-precipitation, pre-incorporation, and ion-exchanging strategies, respectively. It is shown that the preparation method exerted an important effect on the physicochemical property of the sample. Among the OMS-2-supported Pd catalysts, 0.5 wt% Pd/OMS-2-DP possessed the highest surface (Mn2+ + Mn3+)/Mn4+ atomic ratio and the highest surface Pd loading and acid sites. The 0.5 wt% Pd/OMS-2 catalysts outperformed the Pd-free counterpart, among which 0.5 wt% Pd/OMS-2-DP presented the best catalytic activity (T50% and T90% were 25 and 55 °C for CO oxidation, 240 and 285 °C for toluene oxidation, and 160 and 200 °C for ethyl acetate oxidation, respectively). We believe that the high Pd surface loading, high surface atomic ratio of (Mn2+ + Mn3+)/Mn4+, and good low-temperature reducibility, good oxygen mobility, and high acidity were responsible for the excellent performance of the 0.5 wt% Pd/OMS-2-DP catalyst.

    Bakgrunn og formål: Det er cirka 40.000 personer som stammer i Norge. Det er bred enighet i forskningsfeltet om denne vanskens kompleksitet, ikke minst med den variasjonen som kommer til uttrykk. Nyere faglitteratur åpner for at det kan finnes undergrupper av personer som stammer, og det er derfor av interesse å se nærmere på hvilke former for variasjon det her kan være tale om (Yairi, 2007). Douglass og Quarrington (1952) redegjorde tidlig for sitt skille mellom åpen og skjult sekundærstammi...

    En analyse af kvægavlslitteratur fra 1800-tallets anden halvdel viser spændingerne mellem avlernes ønske om profit og hensynene til racerenhed og national og regional identitet. Ideen om den perfekte ko var omdiskuteret og modsætningerne mellem koens udseende og dens ydelse er tydelige i periodens...... bedømmelser af "den gode ko". Artiklen komkluserer at et fokus på opfattelser og brug af dyr kan give nye vinkler på traditionelle historiske emnefelter. Udgivelsesdato: april...

  15. Lille magt, men stort imperium. Et bidrag til debatten om TV og medieimperialisme

    Directory of Open Access Journals (Sweden)

    Niels-Aage Nielsen

    1987-08-01

    Full Text Available Denne artikel tager fat i alt det svære - det begrebsmæssige - som vi enten springer over eller tager for givet i vores diskussioner af TV som magt- og påvirkningsfaktor. Derfor er den lang og til tider lidt omstændelig, idet den undgår at tage vores umiddelbare antagelser for pålydende. I stedet bliver de endevendt. I de seneste 15 års medieforskning har magten været implicit til stede et eller andet sted i TV. Vi har skiftevis kritiseret mediet, frygtet det, taget afstand fra det og er nu senest med receptionsteorierne blevet beroliget: Enhver TV-seer skaber ud fra sin egen sunde fornuft sin personlige opfattelse af "Dollars". Påvirkningen af hende er ikke længere producen- ternes eller medieforskernes eller Danmarks Radios ansvar, det er seerens eget. Medieimperialismen er dermed opløst, ihvertfald som undertrykkelsessystem. Det første kritikpunkt i Niels-Aage Nielsens diskussion er medie- imperialismeteorien. Den har ikke nogen teori om hvordan magten sætter sig igennem hævder han, idet den alene ved cirkler og pile focuserer på ensidigheden i "flow'et" fra USA med resten af verden som modtagere. Hvis det skal udtrykke en magtposition, må der være en relation mellem varestrømmene (basis og den ideologiske overbygning. Vi er vant til at antage, at denne relation findes, men hvordan sætter den sig igennem? Diskussion heraf er - i bedste fald - gået i stå. For at kunne gå videre her, tager Niels-Aage Nielsen et opgør med receptionsteoriens socialpsykologi og søger at afdække hvilken del af betydningsdannelsen, og dermed påvirkningen, som netop unddrager sig en receptionsanalyse, der bygger på seerens egne udsagn og uden f.eks. en psykoanalytisk tilgang. Betydningsproblemet skal endda diskuteres endnu mere pricipielt: Vi er i dag mindre enige end nogensinde om hvad der er TV's samfunds- mæssige funkitioner. Uklarheden hænger bl.a. sammen med at ideologi- begrebet gradvist forsvandt ud af medieforskningens hovedst

    Full Text Available La dernière édition des Apports nutritionnels conseillés (ANC- éd. 2001 souligne la nécessité d’accroître la consommation d’acide alpha-linolénique (ALA. Celle-ci devrait au minimum doubler et représenter 0,8 % (par rapport à l’énergie totale contre 0,34 % actuellement. Or, l’étude Aquitaine [1] a montré que les lipides d’origine animale contribuaient à près de 75 % de l’apport alimentaire en ALA. Ainsi, parmi les stratégies envisageables pour accroître notre consommation d’ALA, sans changer fondamentalement les habitudes alimentaires des Français, on note un intérêt croissant pour augmenter la teneur en oméga 3 des produits animaux via l’alimentation de ces derniers. Quelques exemples de modification de la composition en acides gras des produits animaux sont exposés. Chez les espèces monogastriques (volaille, porc, le profil des lipides de carcasse est un bon reflet des lipides alimentaires. Ainsi, chez le porc, le niveau d’oméga 3 peut être augmenté d’un facteur 2 à 4, lorsque les animaux reçoivent dans leur alimentation de l’huile de colza, des graines de lin ou de la farine de poissons. En revanche, chez les animaux ruminants, le transfert des acides gras polyinsaturés alimentaires vers les tissus est faible en raison de l’hydrogénation qu’ils subissent dans le rumen. Certaines stratégies qui consistent à protéger ces acides gras de la biohydrogénation permettent néanmoins d’accroître le taux d’ALA dans les tissus et le lait. Ainsi, il apparaît possible d’augmenter la consommation d’oméga 3 de la population, via la consommation de produits issus d’animaux nourris avec des sources d’oméga 3. Cependant, au niveau de la production, ces changements doivent être maîtrisés \\; ils ne peuvent se faire sans un contrôle des qualités d’une part organoleptiques, en raison du degré élevé d’oxydabilité de ces acides gras, d’autre part de texture, en raison

Afslutningsvis peger forfatteren på behovet for en ‘Revolution in Diplomatic Affairs’.

  2. An engineering evaluation of the Space Shuttle OMS engine after 5 orbital flights

    Science.gov (United States)

    David, D.

    1983-01-01

    Design features, performances on the first five flights, and condition of the Shuttle OMS engines are summarized. The engines were designed to provide a vacuum-fed 6000 lb of thrust and a 310 sec specific impulse, fueled by a combination of N2O4 and monomethylhydrazine (MMH) at a mixture ratio of 1.65. The design lifetime is 1000 starts and 15 hr of cumulative firing duration. The engine assembly is throat gimballed and features yaw actuators. No degradation of the hot components was observed during the first five flights, and the injector pattern maintained a uniform, enduring level of performance. An increase in the take-off loads have led to enhancing the wall thickness in the nozzle in affected areas. The engine is concluded to be performing to design specifications and is considered an operational system.

    Khakhinov, Vitaly; Alsatkin, Sergey; Medvedev, Andrey; Kushnarev, Dmitriy; Lebedev, Valentin; Potekhin, Alexander; Ratovsky, Konstantin; Shpynev, Boris

    Since 2006 we have carried out active space experiments using the transport spacecraft (TSC) "Progress" and the ground-base Radio-Optic Complex of ISTP SB RAS including Irkutsk Incoherent Scatter Radar (IISR). Engine burns of TSC orbital maneuvering subsystem (OMS) were used as a source of ionospheric disturbances and changing radar signature characteristics of TSC. The flight altitudes were about 340 km. The amount of engine exhaust products was varied from 2 to 11 kg. The flow directions relative to IISR and amount of injected exhaust products were changed from flight to flight. The flows directed to IISR were almost parallel to the geomagnetic field line. For these cases the most pronounced effects were observed, the electron density depletion reached 20-40

  4. Strong coupling effects in non-commutative spaces from OM theory and supergravity

    2000-11-01

    We show that a four-parameter class of 3+1 dimensional NCOS theories can be obtained by dimensional reduction on a general 2-torus from OM theory. Compactifying two spatial directions of NCOS theory on a 2-torus, we study the transformation properties under the SO(2,2; Z) T-duality group. We then discuss non-perturbative configurations of non-commutative super Yang-Mills theory. In particular, we calculate the tension for magnetic monopoles and (p,q) dyons and exhibit their six-dimensional origin, and construct a supergravity solution representing an instanton in the gauge theory. We also compute the potential for a monopole-antimonopole in the supergravity approximation. (author)

  6. Warm Paleocene/Eocene climate as simulated in ECHAM5/MPI-OM

    Directory of Open Access Journals (Sweden)

    2009-12-01

    Full Text Available We investigate the late Paleocene/early Eocene (PE climate using the coupled atmosphere-ocean-sea ice model ECHAM5/MPI-OM. The surface in our PE control simulation is on average 297 K warm and ice-free, despite a moderate atmospheric CO2 concentration of 560 ppm. Compared to a pre-industrial reference simulation (PR, low latitudes are 5 to 8 K warmer, while high latitudes are up to 40 K warmer. This high-latitude amplification is in line with proxy data, yet a comparison to sea surface temperature proxy data suggests that the Arctic surface temperatures are still too low in our PE simulation.

    To identify the mechanisms that cause the PE-PR surface temperature differences, we fit two simple energy balance models to the ECHAM5/MPI-OM results. We find that about 2/3 of the PE-PR global mean surface temperature difference are caused by a smaller clear sky emissivity due to higher atmospheric CO2 and water vapour concentrations in PE compared to PR; 1/3 is due to a smaller planetary albedo. The reduction of the pole-to-equator temperature gradient in PE compared to PR is due to (1 the large high-latitude effect of the higher CO2 and water vapour concentrations in PE compared to PR, (2 the lower Antarctic orography, (3 the smaller surface albedo at high latitudes, and (4 longwave cloud radiative effects. Our results support the hypothesis that local radiative effects rather than increased meridional heat transports were responsible for the "equable" PE climate.

    2017-03-01

    Full Text Available Litteraturen om, hvorledes forskning og undervisning kan integreres på uddannelsesinstitutioner, er vokset betragteligt i de seneste år. Derimod har kun få af disse studier beskæftiget sig med, hvordan studerende oplever forholdet mellem forskning og undervisning. Baseret på et kvalitativt studie af studerendes oplevelse af et forskningsbaseret undervisningsforløb, nærmere bestemt et forskningspraktikforløb, vil denne artikel bidrage til diskussionen med et studenterperspektiv. Vores data viser, at studerende, til trods for at have gennemgået dette forskningsbaserede læringsforløb, stadig oplever forskning og undervisning som adskilte. Vi vil derfor argumentere, at studerende drager et konceptuelt skel mellem forskning og undervisning og betragter disse som to divergerende praksisser. Gennem en analyse af vores data, vil vi vise, at forskningspraktik leder til en afmystificering af studerendes forestillinger om forskning, hvilket udfordrer dette skel. I konklusionen påpeger vi, at en bedre integration af forskning og undervisning kan ske, hvis studerende introduceres til forskningsprocesser gennem hele deres uddannelse. Abstract Literature promoting a close relationship between research and teaching in university has increased significantly in recent years. A walk-through of this literature, shows that only few of these studies have investigated the students’ perspective, though. We intend to fill this gap, by contributing with a qualitative study of students’ experience of research based teaching. This study shows how students experience a divide between research and teaching. This divide, we argue, is primarily on a conceptual level, where the two practices and considered fundamentally different. Our data shows how an internship can lead to a demystification process for these students. This lead to a reevaluation of the conceptual boundary. We argue that a larger focus on research based teaching, throughout the university

    2017-01-01

    Full Text Available La exposición inadecuada en los medios de comunicación sobre suicidios puede producir un efecto contagio o efecto Werther , mientras que determinadas características adecuadas pueden tener un efecto protector o efecto Papageno . Por tanto, los medios de comunicación pueden contribuir a la prevención del suicidio. Por ello, la OMS ha elaborado tres documen- tos con una serie de recomendaciones dirigidas a los profesionales de los medios de comunicación, para el tratamiento de las noticias relacionadas con el suicidio. Sin embargo, solo se ha traducido al español el primero, ambos tienen solapamientos y poseen una estructura diferente. Esto supone que los profesionales de los medios de comunicación de habla hispana en general, y de España en particular, difícilmente pueden tener un acceso a estas recomendaciones de la OMS de una forma clara y concisa. El objetivo de este trabajo fue la elaboración y provisión de un texto único y sintético que recogiera las recomendaciones de estos documentos. Para su creación se siguió un procedimiento formal y estructurado, que aunó criterios científicos y lingüísticos. El texto final contiene las recomendaciones agrupadas en tres categorías: “qué hacer”, “qué no hacer” y “otras recomendaciones”. Este documento puede ser de gran utilidad para los profesionales de los medios de comunicación, para actividades formativas de difusión de tales recomen- daciones con finalidad preventiva y para la investigación.

    2015-07-01

    Full Text Available Abstract: This article describes 10 year old children`s play in nature during school hours. However, my result does equally reflect on children in kindergarden as well. Observation and conversation was used as methods as well as pictures. The children’s play in the trees and building huts was conducted in groups, and their communication was nonverbal with each other and with the nature. However; the girls reveal that they enjoy their conversations while being in the tree. The children often play at the same place over and over. This is significant to the evolution of the play and the children’s communication with their places in nature.Sammendrag: Denne artikkelen omhandler 10 år gamle barns lek på natursteder i skoletida. Selv om studien omhandler 10 åringer så kan kunnskapen den frembringer også være viktig for å forstå barnehagebarns lek og tilknytning til sine lekesteder i barnehagen. Metodene som ble brukt for å undersøke barnas lek var observasjoner og samtaler med barna, i tillegg til fotografier. Barnas lek i trærne og i hyttebyggingen karakteriseres ved at de er flere sammen, og barna har en kroppslig dialog med hverandre og omgivelsene i leken. Barna snakker i liten grad sammen om leken og hvordan de skal leke; deres kommunikasjon er hovedsakelig nonverbal. Men når jentene sitter i treet forteller de meg at de liker å sitte og snakke. Barna leker på steder hvor de har vært mye før, og dette har en betydning for barnas lek og barnas kommunikasjon med deres steder.

    Directory of Open Access Journals (Sweden)

    Marte Sørebø Gulliksen

    2013-01-01

    Full Text Available Artikkelen belyser og diskuterer læreres fagdidaktiske utvelgelseskompetanse i formgiving, kunst og håndverk. Det introduseres en antakelse om at det er mulig og nyttig å anlegge et valgperspektiv på didaktiske handlinger. Det pekes innledningsvis på en del utfordringer med lærerkunnskap, innhold, arbeidsformer og vurdering i faget, knyttet til de krav utfordringene stiller til lærerens utvelgelseskompetanse. Vygotskijs teorier omkring lånte erfaringer og bedømmelses­teorien til Kahneman & Tversky og Kahneman & Fredricks presenteres som et utvalgt teoretisk perspektiv. Det pekes på eksempler fra empiriske studier som har studert faglærerutdanningen i formgiving, kunst og håndverk. Fra disse presenteres og diskuteres situasjoner der valgproblematikk er avgjørende for studentenes læring og mestring av kommende yrkesutøvelse. Valgperspektivet viser seg å kunne gi en mulighet til å se nye potensielle strukturer i den komplekse situasjonen lærerutdanningen i formgiving, kunst og håndverk er: Perspektivet kunne belyse hvordan uklarhet omkring valgmuligheter førte til begrensning. Dessuten kunne det bidra til å problematisere sider av faglærerutdanningens spesialitet: Utfordringen det er å kombinere egen utøving i skapende arbeid og didaktisk utøving- og undervisningskompetanse. Det blir konkludert med at mer forskning er nødvendig, og det blir pekt på at et pågående forskningsprosjekt forhåpentligvis vil kunne bidra til dette, både ved å dokumentere den enkeltes erfaring og ved å studere kritisk om eksemplene i denne artikkelen kan sies å være aktuelle i flere situasjoner. Denne kunnskapen vil kunne styrke det forskningsbaserte grunnlaget for å utdanne lærere med nok utvelgelses­kompetanse til å gjøre gode valg.

    Highlights: • The framework-structured of cryptomelane-type manganese oxide octahedral molecular sieve (OMS-2) has a 2 × 2 square tunnel. • Preparation route has an important impact on physicochemical property of the product. • Pd/OMS-2-DP via the deposition-precipitation route shows excellent catalytic activity. • Pd surface loading, surface atomic ratio of Mn ions, lattice oxygen mobility, oxygen vacancy, reducibility and acidity govern activity. - Abstract: The cryptomelane-type manganese oxide octahedral molecular sieve (OMS-2)-supported Pd (0.5 wt% Pd/OMS-2-DP, 0.5 wt% Pd/OMS-2-PI, and 0.5 wt% Pd/OMS-2-EX) catalysts were prepared by the deposition-precipitation, pre-incorporation, and ion-exchanging strategies, respectively. It is shown that the preparation method exerted an important effect on the physicochemical property of the sample. Among the OMS-2-supported Pd catalysts, 0.5 wt% Pd/OMS-2-DP possessed the highest surface (Mn 2+ + Mn 3+ )/Mn 4+ atomic ratio and the highest surface Pd loading and acid sites. The 0.5 wt% Pd/OMS-2 catalysts outperformed the Pd-free counterpart, among which 0.5 wt% Pd/OMS-2-DP presented the best catalytic activity (T 50% and T 90% were 25 and 55 °C for CO oxidation, 240 and 285 °C for toluene oxidation, and 160 and 200 °C for ethyl acetate oxidation, respectively). We believe that the high Pd surface loading, high surface atomic ratio of (Mn 2+ + Mn 3+ )/Mn 4+ , and good low-temperature reducibility, good oxygen mobility, and high acidity were responsible for the excellent performance of the 0.5 wt% Pd/OMS-2-DP catalyst.

    1992-01-01

    This paper discusses the tendency for the occurrence of tumors in the endocrine glands, other than the thyroid gland, in A-bomb survivors using both autopsy and clinical data. ABCC-RERF sample data using 4136 autopsy cases (1961-1977) revealed parathyroid tumors in 13 A-bomb survivors, including 3 with the associated hyperparathyroidism, with the suggestion of dose-dependent increase in the occurrence of tumors. Based on clinical data from Hiroshima University, 7 (46.7%) of 15 parathyroid tumors cases were A-bomb survivors. Data (1974-1987) from the Tumor Registry Committee (TRC) in Hiroshima Prefecture revealed that a relative risk of parathyroid tumors was 5.6 times higher in the entire group of A-bomb survivors and 16.2 times higher in the group of heavily exposed A-bomb survivors, suggesting the dose-dependent increase in their occurrence. Adrenal tumors were detected in 47 of 123 cases from the TRC data, and 15 (31.5%) of these 47 were A-bomb survivors. Particularly, 11 cases of adrenal tumors associated with Cushing syndrome included 6 A-bomb survivors (54.5%). The incidence of multiple endocrine gonadial tumors (MEGT) tended to be higher with increasing exposure doses; and the 1-9 rad group, the 10-99 rad group, and the 100 or more rad group had a risk of developing MEGT of 4.1, 5.7, and 7.1, respectively, relative to both the not-in the city group and the 0 rad group. These findings suggested that there is a correlation between A-bomb radiation and the occurrence of parathyroid tumors (including hyperparathyroidism), adrenal tumors associated with Cushing syndrome and MEGT (especially, the combined thyroid and ovarian tumors and the combined thyroid and parathyroid tumors).

    In the presence of manganese oxide octahedral molecular sieve (OMS-2) supported copper hydroxide Cu(OH) x /OMS-2, aerobic synthesis of benzoxazoles from catechols and amines via domino oxidation/cyclization at room temperature is achieved. This heterogeneous benzoxazoles synthesis initiated by the efficient oxidation of catechols over Cu(OH) x /OMS-2 tolerates a variety of substrates, especially amines containing sensitive groups (hydroxyl, cyano, amino, vinyl, ethynyl, ester, and even acetyl groups) and heterocycles, which affords functionalized benzoxazoles in good to excellent yields by employing low catalyst loading (2 mol % Cu). The characterization and plausible catalytic mechanism of Cu(OH) x /OMS-2 are described. The notable features of our catalytic protocol such as the use of air as the benign oxidant and EtOH as the solvent, mild conditions, ease of product separation, being scalable up to the gram level, and superior reusability of catalyst (up to 10 cycles) make it more practical and environmentally friendly for organic synthesis.

    Full Text Available Siden anden verdenskrig er antallet af studerende på videregående uddannelser øget dramatisk. Som noget nyt har også professionsbachelorer adgang til visse af univer¬si-teternes kandidatuddannelser. Dette gælder således for kandidatuddannelsen i Læring og Forandringsprocesser på Aalborg Universitet, hvor denne artikels empiri er genereret fra. Artiklen fremlægger resultaterne af en undersøgelse af, hvordan studerende med forskellige uddannelsesbaggrunde må kæmpe om at definere sig selv og medstuderende som akademikere. Artiklens hovedbegreber er taget fra Pierre Bourdieus praktikteori (Bourdieu, 1996; 1997. Det empiriske materiale består af interviews med otte studerende fra samme årgang på kandidatuddannelsen i Læring og Forandringsprocesser. Materialet er bearbejdet ud fra et Bourdieuinspireret, relationelt blik og er kondenseret ned til fremtrædende træk ved forskelligartede strategier. Artiklen viser eksempler på fire studiestrategier, der relaterer sig til, hvordan man som studerende forholder sig til det at arbejde ”akademisk”: En oprørsstrategi der går mod forestillingen om den dominerende universitetskultur ; en strategi der i udgangspunktet ønsker at inkludere og anerkende andre strategier, men med en oplevelse af at motivationen gradvist forsvinder ; en strategi hvor den studerende aktivt afviser og undgår samarbejde med studerende med bestemte uddannel¬ses¬baggrunde, og endelig en kulturelt opadgående strategi der gradvis er lykkedes med at aflæse den ”akademiske kode". The number of students entering higher education since the Second World War has grown dramatically. As a consequence, students from University Colleges are now given admittance to certain master programmes at the established universities. This article presents the results of a study of how students with different educational backgrounds struggle to define themselves and their fellow students as academics.  In this study we focus on

    In this review we introduce the concept of the tumor macroenvironment and explore it in the context of metabolism. Tumor cells interact with the tumor microenvironment including immune cells. Blood and lymph vessels are the critical components that deliver nutrients to the tumor and also connect the tumor to the macroenvironment. Several factors are then released from the tumor itself but potentially also from the tumor microenvironment, influencing the metabolism of distant tissues and organs. Amino acids, and distinct lipid and lipoprotein species can be essential for further tumor growth. The role of glucose in tumor metabolism has been studied extensively. Cancer-associated cachexia is the most important tumor-associated systemic syndrome and not only affects the quality of life of patients with various malignancies but is estimated to be the cause of death in 15%-20% of all cancer patients. On the other hand, systemic metabolic diseases such as obesity and diabetes are known to influence tumor development. Furthermore, the clinical implications of the tumor macroenvironment are explored in the context of the patient's outcome with special consideration for pediatric tumors. Finally, ways to target the tumor macroenvironment that will provide new approaches for therapeutic concepts are described. Copyright © 2014 Elsevier Inc. All rights reserved.

    OMS'05 is the first international conference wholly dedicated to optical microsystems. It was organized by the European Optical Society (EOS) in the frame of its international topical meeting activity and was held in Italy, September 2005, amidst the wonderful scenery of the Island of Capri. A possible definition of an optical microsystem is a complex system, able to perform one or more sensing and actuation functions, where optical devices are integrated in a smart way with electronic, mechanical and sensing components by taking advantage of the progress in micro- and nano-technologies. The increasing interest in this field arises from the expected applications that would significantly improve the quality of life. The list of possibilities offered by the optical microsystem enabling technologies is very long and seems to increase day by day. We are not only thinking about the next generation of optical telecommunication networks and computers, but also about low-cost, compact microsystems for environmental monitoring, in order to improve safety in the avionic and automotive fields, medical diagnostics and proteomic/genomic studies, or just finding general applications in several industrial fields. The goal of the conference was to involve scientists and young researchers from the main public and private laboratories, giving them the opportunity to present new scientific results and compare their know-how in the exciting and emerging field of optical microsystems. We believe that we succeeded in this. More than 200 scientists from all over the world attended the conference. We had more than 100 oral presentations and approximately 20 from the keynote lectures and invited speeches. It was an opportunity to define the most recent progress carried out in the field and to outline the possible road-map leading to the expected results in the industrial and social fields. We strongly believe that research and technology are closely interconnected at present and cannot

    Full Text Available Artikkelen presenterer to nyere studier av veiledning i praksisopplæring i allmennlærerutdannelsen. Hovedfunnene drøftes i forhold til noen tidligere nordiske forskningsstudier. Studiene redegjør for intensjoner og realiteter i praksisopplæringen med fokus på mål, innhold og form i praksisveiledningen. Materialet er ramme- og fagplaner og intervjuer og observasjoner ved tre praksisskoler. Veiledningen drøftes i forhold til teori om veiledning. De to studiene som presenteres, konkluderer med at avstanden mellom teoridel og praksisdel i lærerutdannelsen fortsatt eksisterer. Det blir konstatert både fellestrekk og forskjeller mellom skolene når det gjelder graden av individuell veiledning og gruppeveiledning og individuell studentundervisning. Innholdsfokus i veiledningen varierte. Veilederrollen varierte mellom ettergivenhet og pågåenhet. Noen forskningsstudier hevder at øvingslærere praktiserer teknologisk veiledning. Artikkelen argumenterer for at innvielse i undervisningstradisjonen er nødvendig.

    In this paper, we propose a new parametrization for Om(z) diagnostics and show how the most recent and significantly improved observations concerning the H(z) and SN Ia measurements can be used to probe the consistency or tension between the ΛCDM model and observations. Our results demonstrate that H 0 plays a very important role in the consistency test of ΛCDM with H(z) data. Adopting the Hubble constant priors from Planck 2013 and Riess, one finds considerable tension between the current H(z) data and ΛCDM model and confirms the conclusions obtained previously by others. However, with the Hubble constant prior taken from WMAP9, the discrepancy between H(z) data and ΛCDM disappears, i.e., the current H(z) observations still support the cosmological constant scenario. This conclusion is also supported by the results derived from the Joint Light-curve Analysis (JLA) SN Ia sample. The best-fit Hubble constant from the combination of H(z)+JLA ({H}0={68.81}-1.49+1.50 km s‑1 Mpc‑1) is very consistent with results derived both by Planck 2013 and WMAP9, but is significantly different from the recent local measurement by Riess.

    This paper describes a holistic approach to operation and maintenance (O&M) processes in the domain of offshore wind farm power generation. The acquisition and process visualization is followed by a risk analysis of all relevant processes. Hereafter, a tool was designed, which is able to model the defined processes in a BPMN 2.0 notation, as well as connect and simulate them. Furthermore, the notation was enriched with new elements, representing other relevant factors that were, to date, only displayable with much higher effort. In that regard a variety of more complex situations were integrated, such as for example new process interactions depending on different weather influences, in which case a stochastic weather generator was combined with the business simulation or other wind farm aspects important to the smooth running of the offshore wind farms. In addition, the choices for different methodologies, such as the simulation framework or the business process notation will be presented and elaborated depending on the impact they had on the development of the approach and the software solution. - Highlights: • Analysis of operation and maintenance processes of offshore wind farms • Process modeling with BPMN 2.0 • Domain-specific simulation tool.

    Opsoclonus myoclonus syndrome (OMS) produces long-term cognitive, behavioral, and motor deficits. Objective was to see if more aggressive treatment improved outcome. Assessment included opsoclonus myoclonus syndrome rating, developmental/cognitive and motor assessment, and adaptive behavior. Fourteen subjects completed testing. Nine had neuroblastoma. Onset was at 10 to 35 months; onset to diagnosis: 2 days to 14 months, and onset to first treatment: 5 days to 15 months. Initial treatment was corticotropin (12), oral steroids (3), plus intravenous immunoglobulin in all. Ten received rituximab, 5 cyclophosphamide. Age at testing ranged from 2.5 to 10.3 years. Adaptive Behavior Score (11 subjects), mean 93.5; estimated Intelligence Quotient/Developmental Quotient mean 93.5; Motor: mean 92.8. Residual opsoclonus myoclonus syndrome symptoms at the time of the evaluation were generally minor; opsoclonus myoclonus syndrome scores ranged from 0 to 6. Comparison to previously reported opsoclonus myoclonus syndrome subjects showed improved outcomes: Adaptive behavior, cognitive and motor scores were significantly higher (P < .001) in new subjects. Outcomes have improved with more aggressive immunosuppression, with most opsoclonus myoclonus syndrome survivors now functioning at or near normal. © The Author(s) 2014.

    Three ordered mesoporous siliceous (OMS) materials known as MCM41s-unmodified MCM-41C16 ("C16"), and two MCM41s with different surface functionalities: MCM-41C16-SH ("C16-SH") and MCM-41C16-NH 2 ("C16-NH 2 ")-were synthesized and studied by inverse gas chromatography in order to determine their acceptor-donor properties. The specific retention volumes of nonpolar and polar probes that were chromatographed on these ordered mesoporous silica adsorbents were evaluated under infinite dilution conditions. Two methods were employed to calculate the standard free energy of adsorption, Δ G ads , of each chromatographed probe on the basis its specific retention volume. These Δ G ads values were then employed to estimate the van der Waals contribution and the specific contribution of the free surface energy for each MCM41. DN values (donor numbers, based on the Gutmann scale) and AN* values (acceptor numbers, based on the Riddle-Fowkes scale) were employed to determine the values of parameters that characterize the ability of the MCM41s to act as electron acceptors (parameter: K A ) and donors (parameter: K D ). Considering the different compositions of the probes, each of which has different acceptor-donor properties, a new chromatographic test to supplement the Grob test is suggested.

    To investigate the impact of waiting for psychological therapy on client well-being as measured by the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) global distress (GD) score. Global distress scores were retrieved for all clients referred for psychological therapy in a secondary care mental health service between November 2006 and May 2013 and who had completed a CORE-OM at assessment and first session. GD scores for a subgroup of 103 clients who had completed a CORE-OM during the last therapy session were also reviewed. The study sample experienced a median wait of 41.14 weeks between assessment and first session. The relationship between wait time from referral acceptance to assessment, and assessment GD score was not significant. During the period between assessment and first session no significant difference in GD score was observed. Nevertheless 29.1% of the sample experienced reliable change; 16.0% of clients reliably improved and 13.1% reliably deteriorated whilst waiting for therapy. Demographic factors were not found to have a significant effect on the change in GD score between assessment and first session. Waiting time was associated with post-therapy outcomes but not to a degree which was meaningful. The majority of individuals (54.4%), regardless of whether they improved or deteriorated whilst waiting for therapy, showed reliable improvement at end of therapy as measured by the CORE-OM. The majority of GD scores remained stable while waiting for therapy; however, 29.1% of secondary care clients experienced either reliable improvement or deterioration. Irrespective of whether they improved, deteriorated or remained unchanged whilst waiting for therapy, most individuals who had a complete end of therapy assessment showed reliable improvements following therapy. There was no significant difference in GD score between assessment and first session recordings. A proportion of clients (29.1%) showed reliable change, either improvement or

    Om den effektiva marknadshypotesen inte gäller skulle varje aktie handlas över eller under aktiens verkliga värde. Om så är fallet skulle alla index som är viktade efter börsvärde automatiskt överexponeras när en aktie handlas över dess verkliga värde och underexponera när en aktie handlas under dess verkliga värde. Det här betyder att kapitalviktade index är fundamentalt och strukturellt bristfälliga och kommer kontinuerligt övervikta alla aktier som handlas över verkligt värde och undervikt...

    Many research programs use well-characterized tumor cell lines as tumor models for in vitro studies. Because tumor cells grown as three-dimensional (3-D) structures have been shown to behave more like tumors in vivo than do cells growing in monolayer culture, a growing number of investigators now use tumor cell spheroids as models. Single cell type spheroids, however, do not model the stromal-epithelial interactions that have an important role in controlling tumor growth and development in vivo. We describe here a method for generating, reproducibly, more realistic 3-D tumor models that contain both stromal and malignant epithelial cells with an architecture that closely resembles that of tumor microlesions in vivo. Because they are so tissue-like we refer to them as tumor histoids. They can be generated reproducibly in substantial quantities. The bioreactor developed to generate histoid constructs is described and illustrated. It accommodates disposable culture chambers that have filled volumes of either 10 or 64 ml, each culture yielding on the order of 100 or 600 histoid particles, respectively. Each particle is a few tenths of a millimeter in diameter. Examples of histological sections of tumor histoids representing cancers of breast, prostate, colon, pancreas and urinary bladder are presented. Potential applications of tumor histoids include, but are not limited to, use as surrogate tumors for pre-screening anti-solid tumor pharmaceutical agents, as reference specimens for immunostaining in the surgical pathology laboratory and use in studies of invasive properties of cells or other aspects of tumor development and progression. Histoids containing nonmalignant cells also may have potential as "seeds" in tissue engineering. For drug testing, histoids probably will have to meet certain criteria of size and tumor cell content. Using a COPAS Plus flow cytometer, histoids containing fluorescent tumor cells were analyzed successfully and sorted using such criteria.

    Thermogravimetric studies were carried out in unsintered and sintered samples of uranium oxide, plutonium oxide and uranium-plutonium mixed oxide under different atmospheric conditions (air, argon and moist argon/hydrogen). Moisture loss was found to occur below 200 0 C for uranium dioxide samples, upto 700 0 C for sintered plutonium dioxide and negligible for sintered samples. The O/M ratios for non-stoichiometric uranium dioxide (sintered and unsintered), plutonium dioxide and mixed uranium and plutonium oxides (sintered) could be obtained with a precision of +- 0.002. Two reference states UOsub(2.000) and UOsub(2.656) were obtained for uranium dioxide and the reference state MOsub(2.000) was used for other cases. For unsintered plutonium dioxide samples, accurate O/M ratios could not be obtained of overlap of moisture loss with oxygen loss/gain. (author)

    This study presents a simplified approach for size-controlled synthesis of manganese oxide octahedral molecular sieve (OMS-2) nanowires using potassium permanganate (KMnO4) and different inorganic acids (HCl, HNO3, and H2SO4) under reflux conditions. The morphology and nanostructure of the synthesized products are characterized by X-ray diffraction, Ar adsorption, and electron microscopy analysis, in order to elucidate the controlling effects of acid concentration and type as well as the formation mechanism of OMS-2 nanowires. The concentration of inorganic acid is a crucial factor controlling the phase of the synthesized products. OMS-2 nanowires are obtained with HCl at the concentration ≥0.96 mol/L or with HNO3 and H2SO4 at the concentrations ≥0.72 mol/L. Differently, the type of inorganic acid effectively determines the particle size of OMS-2 nanowires. When the acid is changed from HCl to HNO3 and H2SO4 in the reflux system, the average length of OMS-2 declines significantly by 60-70% (1104-442 and 339 nm), with minor decreased in the average width (43-39 and 34 nm). The formation of OMS-2 nanowires under reflux conditions with KMnO4 and inorganic acids involves a two-step process, i.e., the initial formation of layered manganese oxides, and subsequent transformation to OMS-2 via a dissolution-recrystallization process under acidic conditions. The proposed reflux route provides an alternative approach for synthesizing OMS-2 nanowires as well as other porous nano-crystalline OMS materials.

    This paper presents the results of survey performed to find out how occupational medicine service (OMS) nurses assess their tasks and roles in the Polish system of workers' health protection. The survey was carried out in a random group of 200 OMS nurses. The survey showed that OMS nurses form-an experienced professional group. According to self-assessment they have an opportunity to use their competence in its full scope. Almost half of respondents agreed that in Poland the skills of OMS nurses are properly used. There are two reasons why certain tasks are not performed by OMS nurses, first, certain tasks are assigned to other persons in the unit; second, employers are sometimes not interested in those tasks or find them not necessary. The majority of nurses assess their knowledge and preparation to perform tasks relatively well, however they want to broaden their knowledge and improve their skills. OMS nurses play an important role in the Polish system of workers' health protection. They perform many tasks, which fall within the scope of OMS activities being currently implemented. Their competences are usually properly used. There is a need to convince employers that the scope of services provided by OMS units should be extended and adequately financed. This should result in the better use of OMS nurses' competences. Nurses are well educated and skilled to perform their jobs. Nevertheless, they feel the need to broaden their knowledge. Although the programs of specialization and qualification courses are rather comprehensive, nurses declare that some areas should be enriched with additional information.

Furthermore, it focuses to what extent the directors of these two center categories try to influence school in such questions, and how they possibly may do this. The material derives from a nationwide survey (1310 directors and an interview study (16 directors. The directors experience disagreements to a small extent and least in private centers. However, some disagree about to which extent the adults should lead children’s learning. This study reveals a great variety in how much the directors try to influence school.

    toen oligarchen in staat waren om de controle over de olie-sector te nemen, met name bronnen in Oost-Siberie. Bijvoorbeeld Michael Chodorkovski omzeilde de Moskouse overheid in de voorgestelde bouw van een pijpleiding naar China. Zijn plannen waren alleen gericht op de belangen van zijn bedrijf, terwijl de Russische staat alleen maar een klein deel van de inkomsten zou krijgen. De nieuw opkomende Russische staat onder president Poetin bracht een einde aan dit project en koos voor een route die Rusland de kans zou geven om olie te exporteren naar Japan. De strijd voor deze pijpleiding en de uiteindelijke route biedt een interessante case study van de recente politieke veranderingen in Rusland. Bovendien illustreert het hoe de Russische staat opnieuw de controle kreeg over de energie-industrie en welke rol energie speelt in het buitenlandse economische beleid. Siberische energiebronnen kunnen Rusland helpen deel te nemen aan de economische opkomst van de Aziatisch-Pacifische regio. ESPO is een eerste stap op weg naar Siberie's potentieel en de politieke en economische positie van Rusland in Oost-Azie en daarbuiten te versterken. Vandaar dat de pijplijn een duidelijk signaal is van de economische heropleving in Rusland als een krachtige speler op het Euraziatische continent.

    Full Text Available I dette essayet vil jeg prøve å vise hvordan Åpen forms metode, som ble utviklet i Bergen på 1970-tallet, og som senere har blitt brukt i undervisninga ved Bergen arkitekthøgskole, også kan anvendes som verktøy i faget kunst og håndverk i grunnskolelærerutdanninga. Åpen form undersøker et intersubjektivt og innovativt rom, tuftet på individets erfaringsverden, egenverdi og skapende mot. I et deltakende samspill kan Åpen form kommuniseres inn i en felles forståelse, tolket, utført, vist og avklaret gjennom praktiske handlinger og øvelser. Jeg tar utgangspunkt i 1 Viktor Papaneks tilnærming med at det å forme i seg selv er en grunnleggende menneskelig aktivitet, går videre til Hansjörg Hohrs «estetiske læreprosesser» og fortsetter med 2 Oskar Hansens begrep om «Open Form», praktisert og utviklet av Svein Hatløy og arkitektgruppa Gult Felt gjennom ulike symposier og prosjekter på Vestlandet. Den åpne tilnærminga til form blir belyst spesielt med 3 «Warszawa-spelet» og med et lite eksempel fra egen didaktisk praksis. For videre å underbygge en kunstdidaktisk tilnærming, tolker jeg 4 Åpen forms metode i et fenomenologisk perspektiv og avrunder essayet med min overbevisning om 5 «det estetiske som kunnskapsform» i forlengelse av definisjonen til pedagogene Austring og Sørensen og min egen erfaring fra praksis som kunstner og som lærer i arbeid med form. Åpen form som metode har referanser i kunstfeltets mangfoldige estetiske praksiser. Denne tenkinga kan la seg utvikle og bruke som en didaktisk formel også i mer almendannende undervisning. Som lærerutdanner med kunstfaglig bakgrunn, ser jeg her en mulighet til å styrke og synliggjøre estetiske læreprosesser i grunnskolelærerutdanninga. Metoden representerer en åpen og praktisk undersøkende holdning til form i et materielt og romlig uttrykk. I et forsøk på å løfte fram dette enkle men anvendelige tenkesettet, vil jeg trekke inn både biografiske og

    2018-04-01

    Aerosols have adverse effects on human health and air quality, changing Earth's energy balance and lead to climate change. The components of aerosol are important because of the different spectral characteristics. Based on the low hygroscopic and high scattering properties of organic matter (OM) in fine modal atmospheric aerosols, we develop an inversion algorithm using remote sensing to obtain aerosol components including black carbon (BC), organic matter (OM), ammonium nitrate-like (AN), dust-like (DU) components and aerosol water content (AW). In the algorithm, the microphysical characteristics (i.e. volume distribution and complex refractive index) of particulates are preliminarily separated to fine and coarse modes, and then aerosol components are retrieved using bimodal parameters. We execute the algorithm using remote sensing measurements of sun-sky radiometer at AERONET site (Beijing RADI) in a period from October of 2014 to January of 2015. The results show a reasonable distribution of aerosol components and a good fit for spectral feature calculations. The mean OM mass concentration in atmospheric column is account for 14.93% of the total and 56.34% of dry and fine-mode aerosol, being a fairly good correlation (R = 0.56) with the in situ observations near the surface layer.

    The authors review the main indications of PET examination, and specifically of 18 FDG, in the assessment of endocrine tumors: of the thyroid, of the parathyroid, of the adrenal and of the pituitary glands. Neuroendocrine tumors, gastro-entero-pancreatic or carcinoid tumors are also under the scope. Usually, the most differentiated tumors show only poor uptake of the FDG as they have a weak metabolic and proliferative activity. In the assessment of endocrine tumors, FDG-PET should be used only after most specific nuclear examinations been performed. (author)

  8. Tumor penetrating peptides

    2013-08-01

    Full Text Available Tumor-homing peptides can be used to deliver drugs into tumors. Phage library screening in live mice has recently identified homing peptides that specifically recognize the endothelium of tumor vessels, extravasate, and penetrate deep into the extravascular tumor tissue. The prototypic peptide of this class, iRGD (CRGDKGPDC, contains the integrin-binding RGD motif. RGD mediates tumor homing through binding to αv integrins, which are selectively expressed on various cells in tumors, including tumor endothelial cells. The tumor-penetrating properties of iRGD are mediated by a second sequence motif, R/KXXR/K. This C-end Rule (or CendR motif is active only when the second basic residue is exposed at the C-terminus of the peptide. Proteolytic processing of iRGD in tumors activates the cryptic CendR motif, which then binds to neuropilin-1 activating an endocytic bulk transport pathway through tumor tissue. Phage screening has also yielded tumor-penetrating peptides that function like iRGD in activating the CendR pathway, but bind to a different primary receptor. Moreover, novel tumor-homing peptides can be constructed from tumor-homing motifs, CendR elements and protease cleavage sites. Pathologies other than tumors can be targeted with tissue-penetrating peptides, and the primary receptor can also be a vascular zip code of a normal tissue. The CendR technology provides a solution to a major problem in tumor therapy, poor penetration of drugs into tumors. The tumor-penetrating peptides are capable of taking a payload deep into tumor tissue in mice, and they also penetrate into human tumors ex vivo. Targeting with these peptides specifically increases the accumulation in tumors of a variety of drugs and contrast agents, such as doxorubicin, antibodies and nanoparticle-based compounds. Remarkably the drug to be targeted does not have to be coupled to the peptide; the bulk transport system activated by the peptide sweeps along any compound that is

    Full Text Available Abstract Background Current understanding on the relationships between hypoxia, hypoxia-inducible factor-1 (HIF-1 and telomerase reverse transcriptase (TERT gene expression are largely based on in vitro studies in human cancer cells. Although several reports demonstrated HIF-1- mediated upregulation of the human TERT gene under hypoxia, conflicting findings have also been reported. Thus far, it remains uncertain whether these findings can be directly extrapolated to non-tumor tissues in other whole animal systems in vivo. While fish often encounter environmental hypoxia, the in vivo regulation of TERT by hypoxia in non-neoplastic tissues of fish remains virtually unknown. Results The adult marine medaka (Oryzias melastigma was employed as a model fish in this study. We have cloned and characterized a 3261-bp full-length TERT cDNA, omTERT, which encodes a protein of 1086 amino acids. It contains all of the functional motifs that are conserved in other vertebrate TERTs. Motif E is the most highly conserved showing 90.9–100% overall identity among the fish TERTs and 63.6% overall identity among vertebrates. Analysis of the 5'-flanking sequence of the omTERT gene identified two HRE (hypoxia-responsive element; nt. – 283 and – 892 cores. Overexpression of the HIF-1α induced omTERT promoter activity as demonstrated using transient transfection assays. The omTERT gene is ubiquitously expressed in fish under normoxia, albeit at varying levels, where highest expression was observed in gonads and the lowest in liver. In vivo expression of omTERT was significantly upregulated in testis and liver in response to hypoxia (at 96 h and 48 h, respectively, where concomitant induction of the omHIF-1α and erythropoietin (omEpo genes was also observed. In situ hybridization analysis showed that hypoxic induction of omTERT mRNA was clearly evident in hepatocytes in the caudal region of liver and in spermatogonia-containing cysts in testis.

    @@ Epidemiology It is estimated 61,414 new cases of primary brain tumors are expected to be diagnosed in 2009 in the U.S. The incidence statistic of 61,414 persons diagnosed per year includes both malignant (22,738) and non-malignant (38,677) brain tumors. (Data from American Brain Tumor Association). During the years 2004-2005, approximately 359,000 people in the United States were living with the diagnosis of a primary brain or central nervous system tumor. Specifically, more than 81,000 persons were living with a malignant tumor, more than 267,000 persons with a benign tumor. For every 100,000 people in the United States, approximately 131 are living following the diagnosis of a brain tumor. This represents a prevalence rate of 130.8 per 100,000 person years[1].

    Graphical abstract: Oxidation of various alcohols is studied in the liquid phase over new composite mixed oxide (V 2 O 5 /OMS-2) catalyst using tert-butyl hydroperoxide (TBHP). The activity of V 2 O 5 /OMS-2 samples was considerably increased with respect to OMS-2 catalyst and these samples are found to be suitable for the selective oxidation of alcohols. - Highlights: • V 2 O 5 /K-OMS-2 with different V/Mn molar ratios prepared by the impregnation method. • Oxidation of alcohols was studied in the liquid phase over V 2 O 5 /K-OMS-2 catalyst. • V 2 O 5 /K-OMS-2 catalyst had excellent activity for alcohol oxidation. • Benzyl alcohol oxidation using excess TBHP followed a pseudo-first order kinetic. • The selected catalyst was reused without significant loss of activity. - Abstract: This work reports the synthesis and characterization of mixed oxide vanadium–manganese V 2 O 5 /K-OMS-2 at various V/Mn molar ratios and prepared by the impregnation method. Characterization of these new composite materials was made by elemental analysis, BET, XRD, FT-IR, SEM and TEM techniques. Results of these analyses showed that vanadium impregnated samples contained mixed phases of cryptomelane and crystalline V 2 O 5 species. Oxidation of various alcohols was studied in the liquid phase over the V 2 O 5 /K-OMS-2 catalyst using tert-butyl hydroperoxide (TBHP) and H 2 O 2 as the oxidant. Activity of the V 2 O 5 /K-OMS-2 samples was increased considerably with respect to K-OMS-2 catalyst due to the interaction of manganese oxide and V 2 O 5 . The kinetic of benzyl alcohol oxidation using excess TBHP over V 2 O 5 /K-OMS-2 catalyst was investigated at different temperatures and a pseudo-first order reaction was determined with respect to benzyl alcohol. The effects of reaction time, oxidant/alcohol molar ratio, reaction temperature, solvents, catalyst recycling potential and leaching were investigated

    Despite having been much debated, it is now well established that the immune system plays an essential role in the fight against cancer. In this article, we will highlight the implication of the immune system in the control of tumor growth and describe the major components of the immune system involved in the antitumoral immune response. The immune system, while exerting pressure on tumor cells, also will play a pro-tumoral role by sculpting the immunogenicity of tumors cells as they develop. Finally, we will illustrate the numerous mechanisms of immune suppression that take place within the tumoral microenvironment which allow tumor cells to escape control from the immune system. The increasingly precise knowledge of the brakes to an effective antitumor immune response allows the development of immunotherapy strategies more and more innovating and promising of hope.

    Ductal adenocarcinoma is the most frequent solid tumor of the pancreas. This tumor has distinct features including early obstruction of the pancreatic duct, diminished enhancement after administration of contrast material due to desmoplastic growth, high propensity to infiltrate adjacent structures and to metastasize into the liver and the peritoneum. Hormone active endocrine tumors cause specific clinical symptoms. Imaging is aimed at localization of these hypervascular tumors. Non hormone active tumors are most frequently malignant and demonstrate very varying features. Cystic pancreatic tumors are increasingly detected by means of cross sectional imaging. Exact classification can be achieved with knowledge of the macropathology and considering clinical presentation as well as age and gender of the patients. (orig.)

    Mobile phone induced electromagnetic field (MPEMF) as well as chanting of Vedic mantra 'OM' has been shown to affect cognition and brain haemodynamics, but findings are still inconclusive. Twenty right-handed healthy teenagers (eight males and 12 females) in the age range of 18.25 ± 0.44 years were randomly divided into four groups: (1) MPONOM (mobile phone 'ON' followed by 'OM' chanting); (2) MPOFOM (mobile phone 'OFF' followed by 'OM' chanting); (3) MPONSS (mobile phone 'ON' followed by 'SS' chanting); and (4) MPOFSS (mobile phone 'OFF' followed by 'SS' chanting). Brain haemodynamics during Stroop task were recorded using a 64-channel fNIRS device at three points of time: (1) baseline, (2) after 30 min of MPON/OF exposure, and (3) after 5 min of OM/SS chanting. RM-ANOVA was applied to perform within- and between-group comparisons, respectively. Between-group analysis revealed that total scores on incongruent Stroop task were significantly better after OM as compared to SS chanting (MPOFOM vs MPOFSS), pre-frontal activation was significantly lesser after OM as compared to SS chanting in channel 13. There was no significant difference between MPON and MPOF conditions for Stroop performance, as well as brain haemodynamics. These findings need confirmation through a larger trial in future.

    Intrinsic tumors of the central nervous system (CNS) pose a particularly challenging problem to practicing oncologists. These tumors rarely metastasize outside the CNS, yet even histologically benign tumors can be life-threatening due to their local invasiveness and strategic location. The surrounding normal tissues of the nervous system is often incapable of full functional regeneration, therefore prohibiting aggressive attempts to use either complete surgical resection or high doses of irradiation. Despite these limitations, notable achievements have recently been recorded in the management of these tumors

    The treatment of tumors of the CNS has undergone a number of changes based on the impact of CT. The use of intraoperative US for the establishment of tumor location and tumor histology is demonstrated. MR imaging also is beginning to make an impact on the diagnosis and treatment of tumors of the CNS. Examples of MR images are shown. The authors then discuss the important aspects of tumor histology as it affects management and newer concepts in surgery, radiation, and chemotherapy on tumor treatment. The role of intraoperative placement of radioactive sources, the utilization of heavy particle radiation therapy, and the potential role of other experimental radiation therapy techniques are discussed. The role of hyperfractionated radiation and of neutrons and x-ray in a mixed-beam treatment are discussed in perspective with standard radiation therapy. Current chemotherapy techniques, including intraarterial chemotherapy, are discussed. The complications of radiation therapy alone and in combination with chemotherapy in the management of primary brain tumors, brain metastases, and leukemia are reviewed. A summary of the current management of pituitary tumors, including secreting pituitary adenomas and chromophobe adenomas, are discussed. The treatment with heavy particle radiation, transsphenoidal microsurgical removal, and combined radiotherapeutic and surgical management are considered. Tumor metastasis management of lesions of the brain and spinal cord are considered

    This article gives an overview of the most common tumors of the pituitary gland and the differential diagnostics with special emphasis on radiological diagnostic criteria. A selective search of the literature in PubMed was carried out. Pituitary adenomas constitute 10-15 % of all intracranial tumors and are the most common tumors of the sellar region. Tumors smaller than 1 cm in diameter are called microadenomas while those larger than 1 cm in diameter are called macroadenomas. Approximately 65 % of pituitary gland adenomas secrete hormones whereby approximately 50 % secrete prolactin, 10 % secrete growth hormone (somatotropin) and 6 % secrete corticotropin. Other tumors located in the sella turcica can also cause endocrinological symptoms, such as an oversecretion of pituitary hormone or pituitary insufficiency by impinging on the pituitary gland or its stalk. When tumors spread into the space cranial to the sella turcica, they can impinge on the optic chiasm and cause visual disorders. A common differential diagnosis of a sellar tumor is a craniopharyngeoma. In children up to 10 % of all intracranial tumors are craniopharyngeomas. Other differential diagnoses for sellar tumors are metastases, meningiomas, epidermoids and in rare cases astrocytomas, germinomas or Rathke cleft cysts As these tumors are located in an anatomically complex region of the skull base and are often very small, a highly focused imaging protocol is required. The currently favored modality is magnetic resonance imaging (MRI) with the administration of a contrast agent. The sellar region should be mapped in thin slices. In cases of suspected microadenoma the imaging protocol should also contain a sequence with dynamic contrast administration in order to assess the specific enhancement characteristics of the tumor and the pituitary gland.

    Shame is an ineffective tool in residency education that often results in depression, isolation, and worse patient care. This study aimed to assess burnout, depersonalization, and personal achievement levels in current oral and maxillofacial surgery (OMS) residents, to assess the prevalence of the use of shame in OMS residency training, and to determine whether there is a relation between shame exposure and resident burnout, depersonalization, and personal achievement levels. An anonymous 20-question cross-sectional survey was developed incorporating the Maslach Burnout Index and a previously validated shame questionnaire and sent to all OMS program directors affiliated with the American Association of Oral and Maxillofacial Surgeons for distribution among their respective residents in 2016. Univariate analyses were used to determine the distribution of the predictor (shame) and outcome (burnout) by gender and by frequency of shaming events. Multivariable logistic regression analysis was used to assess the relation of shame to burnout. A 2-sided P value less than .05 was considered statistically significant. Two hundred seventeen responses were received; 82% of respondents were men (n = 178), 95% were 25 to 34 years old (n = 206), and 58% (n = 126) were enrolled in a 4-year program. Frequently shamed residents were more likely to have depression (58 vs 22%; P < .0001), isolation (55 vs 22%; P < .0001), and poor job performance (50 vs 30%; P < .0001). Residents who were frequently shamed were more likely to experience moderate to severe burnout (odds ratio = 4.6; 95% confidence interval, 2.1-10.0; P < .001) and severe depersonalization (odds ratio = 5.1; 95% confidence interval, 2.1-12.0; P < .0001) than residents who had never or infrequently been shamed. There is a clear relation between the number of shame events and burnout and depersonalization levels. It is important to understand the negative impact that the experience of shame has on residents

    2014-01-01

    Background Diminishing stigmatization for those with mental illnesses by health care providers (HCPs) is becoming a priority for programming and policy, as well as research. In order to be successful, we must accurately measure stigmatizing attitudes and behaviours among HCPs. The Opening Minds Stigma Scale for Health Care Providers (OMS-HC) was developed to measure stigma in HCP populations. In this study we revisit the factor structure and the responsiveness of the OMS-HC in a larger, more representative sample of HCPs that are more likely to be targets for anti-stigma interventions. Methods Baseline data were collected from HCPs (n = 1,523) during 12 different anti-stigma interventions across Canada. The majority of HCPs were women (77.4%) and were either physicians (MDs) (41.5%), nurses (17.0%), medical students (13.4%), or students in allied health programs (14.0%). Exploratory factor analysis (EFA) was conducted using complete pre-test (n = 1,305) survey data and responsiveness to change analyses was examined with pre and post matched data (n = 803). The internal consistency of the OMS-HC scale and subscales was evaluated using the Cronbach’s alpha coefficient. The scale’s sensitivity to change was examined using paired t-tests, effect sizes (Cohen’s d), and standardized response means (SRM). Results The EFA favored a 3-factor structure which accounted for 45.3% of the variance using 15 of 20 items. The overall internal consistency for the 15-item scale (α = 0.79) and three subscales (α = 0.67 to 0.68) was acceptable. Subgroup analysis showed the internal consistency was satisfactory across HCP groups including physicians and nurses (α = 0.66 to 0.78). Evidence for the scale’s responsiveness to change occurred across multiple samples, including student-targeted interventions and workshops for practicing HCPs. The Social Distance subscale had the weakest level of responsiveness (SRM ≤ 0.50) whereas the more attitudinal

    To discuss the concept of pseudoanaplastic tumors of bone, which pathologically show hyperchromatism and marked pleomorphism with quite enlarged, pleomorphic nuclei, but with no to extremely rare, typical mitoses, and to propose guidelines for their diagnosis. From a database of 4,262 bone tumors covering from 1971 to 2001, 15 cases of pseudoanaplastic bone tumors (0.35% of total) were retrieved for clinical, radiographic and pathologic review. Postoperative follow-up after surgical treatment was at least 3 years and a maximum of 7 years. There were eight male and seven female patients. Their ages ranged from 10 to 64 years with average of 29.7 years. Pathologic diagnoses of pseudoanaplastic variants of benign bone tumors included: osteoblastoma (4 cases), giant cell tumor (4 cases), chondromyxoid fibroma (3 cases), fibrous dysplasia (2 cases), fibrous cortical defect (1 case) and aneurysmal bone cyst (1 case). Radiography of all cases showed features of a benign bone lesion. Six cases, one case each of osteoblastoma, fibrous dysplasia, aneurysmal bone cyst, chondromyxoid fibroma, giant cell tumor and osteoblastoma, were initially misdiagnosed as osteosarcoma. The remaining cases were referred for a second opinion to rule out sarcoma. Despite the presence of significant cytologic aberrations, none of our cases showed malignant behavior following simple curettage or removal of bony lesions. Our observation justifies the concept of pseudoanaplasia in some benign bone tumors as in benign soft tissue tumors, especially in their late evolutionary stage when bizarre cytologic alterations strongly mimic a sarcoma.

    Immunohistochemical studies for neuronal differentiation in glial tumors revealed subsets of tumors having both characteristics of glial and neuronal lineages. Glial tumors with neuronal differentiation can be observed with diverse phenotypes and histologic grades. The rosette-forming glioneuronal tumor of the fourth ventricle and papillary glioneuronal tumor have been newly classified as distinct disease entities. There are other candidates for classification, such as the glioneuronal tumor without pseudopapillary architecture, glioneuronal tumor with neuropil-like islands, and the malignant glioneuronal tumor. The clinical significance of these previously unclassified tumors should be confirmed. Copyright © 2015 Elsevier Inc. All rights reserved.

    The radiological findings in pulmonary lymphangitic carcinomatosis and in leukemic pulmonary infiltrates mirror the tumor-dependent monomorphic interstitial pathology of lung parenchyma. It is a proven fact that pulmonary lymphangitic carcinomatosis is caused by hematogenous tumor embolization to the lungs; pathogenesis by contiguous lymphangitic spread is the exception. High-resolution CT performed as a supplement to the radiological work-up improves the sensitivity for pulmonary infiltrates in general and thus makes the differential diagnosis decided easier. Radiological criteria cannot discriminate the different forms of leukemia. Plain chest X-ray allows the diagnosis of pulmonary involvement in leukemia due to tumorous infiltrates and of tumor- or therapy-induced complications. It is essential that the radiological findings be interpreted with reference to the stage of tumor disease and the clinical parameters to make the radiological differential diagnosis of opportunistic infections more reliable.

    Differentiation between malignant and benign tumors of peripheral nerves in the early stages is challenging; however, due to the unfavorable prognosis of malignant tumors early identification is required. To show the possibilities for detection, differential diagnosis and clinical management of peripheral nerve tumors by imaging appearance in magnetic resonance (MR) neurography. Review of current literature available in PubMed and MEDLINE, supplemented by the authors' own observations in clinical practice. Although not pathognomonic, several imaging features have been reported for a differentiation between distinct peripheral nerve tumors. The use of MR neurography enables detection and initial differential diagnosis in tumors of peripheral nerves. Furthermore, it plays an important role in clinical follow-up, targeted biopsy and surgical planning. (orig.) [de

    Wilms' tumor occurs extremely rarely in adults. There is no consensus in the literature on the problems of clinical manifestations, diagnosis and treatment of the diseasa. Ten adult patients (aged 16-29) with Wilms' tumor formed the study group. They made up 0.9 per cent of the total number of kidney tumor patients. The peculiarities of the clinical course that distinguish adult nephroblastoma from renal cancer and Wilms' tumor of the infancy were analysed. The latent period appeared to be long. Problems of diagnosis are discussed. Angiography proved to be of the highest diagnostic value. Complex treatment including transperitoneal nephrectory, radiation and chemotherapy was carried out in 7 cases, palliative radiation treatmenchemotherapy andn 3. Unlike pediatric nephroblastomt - i Wilms' tumor in adults was resistant to radiation. Treatment results still remained unsatisfactory: 6 patients died 7-19 months after the beginning of treatment

    1984-01-01

    Radiotherapy has universally been used in the treatment of pineal tumors and suprasellar germinomas. Recently however, major technical advances related to the use of the operating microscope and development of microsurgical techniques have prompted a renewed interest in the direct surgical approach for biopsy and/or excision. This interest has resulted in a controversy regarding the role of surgery prior to radiotherapy. Because of the heterogeneity of tumors occurring in the pineal region (i.e., germ cell tumors, pineal parenchymal tumors, glial tumors, and cysts) and their differing biological behavior, controversy also surrounds aspects of radiotherapy such as: the optimal radiation dose, the volume to be irradiated, and indications for prophylactic spinal irradiation. A review of the available data is presented in an attempt to answer these questions

  3. Ordered micro/macro porous K-OMS-2/SiO2 nanocatalysts: Facile synthesis, low cost and high catalytic activity for diesel soot combustion

    2017-04-01

    A series of novel oxide catalysts, which contain three-dimensionally ordered macroporous (3DOM) and microporous structure, were firstly designed and successfully synthesized by simple method. In the as-prepared catalysts, 3DOM SiO2 is used as support and microporous K-OMS-2 oxide nanoparticles are supported on the wall of SiO2. 3DOM K-OMS-2/SiO2 oxide catalysts were firstly used in soot particle oxidation reaction and they show very high catalytic activities. The high activities of K-OMS-2/SiO2 oxide catalysts can be assigned to three possible reasons: macroporous effect of 3DOM structure for improving contact between soot and catalyst, microporous effect of K-OMS-2 for adsorption of small gas molecules and interaction of K and Mn for activation of gas molecules. The catalytic activities of catalysts are comparable to or even higher than noble metal catalyst in the medium and high temperature range. For example, the T50 of K-OMS-2/SiO2-50, 328 °C, is much lower than those of Pt/Al2O3 and 3DOM Au/LaFeO3, 464 and 356 °C,respectively. Moreover, catalysts exhibited high catalytic stability. It is attributed to that the K+ ions are introduced into the microporous structure of OMS-2 and stabilized in the catalytic reaction. Meanwhile, the K+ ions play an important role in templating and stabilizing the tunneled framework of OMS-2.

    Background. The aim of this study was to investigate myofibroblast (MF) density in a broad spectrum of odontogenic cysts and tumors and the relation between the density of MFs and the clinical behavior of these lesions. Methods. A total of 105 cases of odontogenic lesions, including unicystic ameloblastoma (UAM), solid ameloblastoma (SA), odontogenic keratocyst (OKC), dentigerous cyst (DC), radicular cyst (RC) (15 for each category), and odontogenic myxoma (OM), adenomatoid odontogenic tumor (AOT), calcifying odontogenic cyst (COC) (10 for each category), were immunohistochemically stained with anti-α-smooth muscle actin antibody. The mean percentage of positive cells in 10 high-power fields was considered as MF density for each case. Results. A statistically significant difference was observed in the mean scores between the study groups (P 0.05). The number of MFs was significantly higher in OKC and lower in COC compared to other odontogenic cysts (P = 0.007 and P = 0.045, respectively). Conclusion. The results of the present study suggest a role for MFs in the aggressive behavior of odontogenic lesions. MFs may represent an important target of therapy, especially for aggressive odontogenic lesions. Our findings support the classification of OKC in the category of odontogenic tumors.

    Tumor control and regrowth probability of animal tumors irradiated with a single x-ray dose were determined, using a spontaneous C3H mouse mammary carcinoma. Cellular radiation sensitivity of tumor cells and tumor control probability of the tumor were examined by the TD 50 and TCD 50 assays respectively. Tumor growth kinetics were measured by counting the percentage of labelled mitosis and by measuring the growth curve. A mathematical analysis of tumor control probability was made from these results. A formula proposed, accounted for cell population kinetics or division probability model, cell sensitivity to radiation and number of tumor cells. (auth.)

    During tumor progression, alterations within the systemic tumor environment, or macroenvironment, result in the promotion of tumor growth, tumor invasion to distal organs, and eventual metastatic disease. Distally produced hormones, commensal microbiota residing within mucosal surfaces, myeloid cells and even the bone marrow impact the systemic immune system, tumor growth, and metastatic spread. Understanding the reciprocal interactions between the cells and soluble factors within the macroenvironment and the primary tumor will enable the design of specific therapies that have the potential to prevent dissemination and metastatic spread. This chapter will summarize recent findings detailing how the primary tumor and systemic tumor macroenvironment coordinate malignant progression. © 2015 Elsevier Inc. All rights reserved.

    Sottnik, Joseph L; Zhang, Jian; Macoska, Jill A; Keller, Evan T

    2011-12-01

    The tumor microenvironment (TME) is a very complex niche that consists of multiple cell types, supportive matrix and soluble factors. Cells in the TME consist of both host cells that are present at tumor site at the onset of tumor growth and cells that are recruited in either response to tumor- or host-derived factors. PCa (PCa) thrives on crosstalk between tumor cells and the TME. Crosstalk results in an orchestrated evolution of both the tumor and microenvironment as the tumor progresses. The TME reacts to PCa-produced soluble factors as well as direct interaction with PCa cells. In return, the TME produces soluble factors, structural support and direct contact interactions that influence the establishment and progression of PCa. In this review, we focus on the host side of the equation to provide a foundation for understanding how different aspects of the TME contribute to PCa progression. We discuss immune effector cells, specialized niches, such as the vascular and bone marrow, and several key protein factors that mediate host effects on PCa. This discussion highlights the concept that the TME offers a potentially very fertile target for PCa therapy.

    2016-01-01

    Seizures are common in patients with brain tumors, and epilepsy can significantly impact patient quality of life. Therefore, a thorough understanding of rates and predictors of seizures, and the likelihood of seizure freedom after resection, is critical in the treatment of brain tumors. Among all tumor types, seizures are most common with glioneuronal tumors (70–80%), particularly in patients with frontotemporal or insular lesions. Seizures are also common in individuals with glioma, with the highest rates of epilepsy (60–75%) observed in patients with low-grade gliomas located in superficial cortical or insular regions. Approximately 20–50% of patients with meningioma and 20–35% of those with brain metastases also suffer from seizures. After tumor resection, approximately 60–90% are rendered seizure-free, with most favorable seizure outcomes seen in individuals with glioneuronal tumors. Gross total resection, earlier surgical therapy, and a lack of generalized seizures are common predictors of a favorable seizure outcome. With regard to anticonvulsant medication selection, evidence-based guidelines for the treatment of focal epilepsy should be followed, and individual patient factors should also be considered, including patient age, sex, organ dysfunction, comorbidity, or cotherapy. As concomitant chemotherapy commonly forms an essential part of glioma treatment, enzyme-inducing anticonvulsants should be avoided when possible. Seizure freedom is the ultimate goal in the treatment of brain tumor patients with epilepsy, given the adverse effects of seizures on quality of life. PMID:26948360

  11. CNS tumors: postoperative evaluation

    2012-01-01

    Full text: Imaging assessment of brain tumors following surgery is complex and depends upon several factors, including the location of the tumor, the surgical procedure and the disease process for which it was performed. Depending upon these factors, one or a combination of complementary imaging modalities may be required to demonstrate any clinically relevant situation, to assist the surgeon in deciding if repeat surgery is necessary. Conventional magnetic resonance imaging (MRI) can show the shape, size, signal intensity, and enhancement of a brain tumor. It has been widely used to diagnose and differentiate brain tumors and to assess the surgery outcomes. Longitudinal MRI scans have also been applied for the assessment of treatment and response to surgery. The newly developed MRI techniques, including diffusion weighted imaging (DWI), perfusion weighted imaging (PWI) and magnetic resonance spectroscopy (MRS), have the potential to provide the molecular, functional and metabolic information of preoperative and postoperative brain tumors. Postoperative diffusion and perfusion magnetic resonance imaging are especially useful in predicting early functional recovery from new deficits after brain tumor surgery.This lecture will stress the principles, applications, and pitfalls of conventional as well as newly developing functional imaging techniques following operation of brain tumors

    Cell surface proteins mediate interaction between cells and their environment. Unique tumor cell surface proteins are being identified and quantified in several tumor systems to address the following questions: (i) how do tumor-specific proteins arise during cell transformation; (ii) can these proteins be used as markers of tumor cell distribution in vivo; (iii) can cytotoxic drugs be targeted specifically to tumor cells using antibody; and (iv) can solid state radioimmunoassay of these proteins provide a means to quantify transformation frequencies. A tumor surface protein of 180,000 M/sub r/ (TSP-180) has been identified on cells of several lung carcinomas of BALB/c mice. TSP-180 was not detected on normal lung tissue, embryonic tissue, or other epithelial or sarcoma tumors, but it was found on lung carcinomas of other strains of mice. Considerable amino acid sequence homology exists among TSP-180's from several cell sources, indicating that TSP-180 synthesis is directed by normal cellular genes although it is not expressed in normal cells. The regulation of synthesis of TSP-180 and its relationship to normal cell surface proteins are being studied. Monoclonal antibodies (MoAb) to TSP-180 have been developed. The antibodies have been used in immunoaffinity chromatography to isolate TSP-180 from tumor cell sources. This purified tumor antigen was used to immunize rats. Antibody produced by these animals reacted at different sites (epitopes) on the TSP-180 molecule than did the original MoAb. These sera and MoAb from these animals are being used to identify normal cell components related to the TSP-180 molecule

    Central nervous system (CNS) tumors are relatively common in veterinary medicine, with most diagnoses occurring in the canine and feline species. Numerous tumor types from various cells or origins have been identified with the most common tumors being meningiomas and glial cell tumors. Radiation therapy is often used as an aid to control the clinical signs associated with these neoplasms. In general, these tumors have a very low metastatic potential, such that local control offers substantial benefit. Experience in veterinary radiation oncology would indicate that many patients benefit from radiation treatment. Current practice indicates the need for computed tomography or magnetic resonance imaging studies. These highly beneficial studies are used for diagnosis, treatment planning, and to monitor treatment response. Improvements in treatment planning and radiation delivered to the tumor, while sparing the normal tissues, should improve local control and decrease potential radiation related problems to the CNS. When possible, multiple fractions of 3 Gy or less should be used. The tolerance dose to the normal tissue with this fractionation schedule is 50 to 55 Gy. The most common and serious complications of radiation for CNS tumors is delayed radiation myelopathy and necrosis. Medical management of the patient during radiation therapy requires careful attention to anesthetic protocols, and medications to reduce intracranial pressure that is often elevated in these patients. Canine brain tumors have served as an experimental model to test numerous new treatments. Increased availability of advanced imaging modalities has spawned increased detection of these neoplasms. Early detection of these tumors with appropriate aggressive therapy should prove beneficial to many patients

    2006-01-01

    Strong experimental evidence has indicated that tumor growth belongs to the molecular beam epitaxy universality class. This type of growth is characterized by the constraint of cell proliferation to the tumor border, and surface diffusion of cells at the growing edge. Tumor growth is thus conceived as a competition for space between the tumor and the host, and cell diffusion at the tumor border is an optimal strategy adopted for minimizing the pressure and helping tumor development. Two stoch...

    Full Text Available Uterine mesenchymal tumors are a heterogeneous group of neoplasms that can frequently be diagnostically challenging. Differentiation between the benign and malignant counterparts of mesenchymal tumors is significant due to differences in clinical outcome, and the role of the surgical pathologist in making this distinction (especially in the difficult cases cannot be underestimated. Although immunohistochemical stains are supportive toward establishing a final diagnosis, the morphologic features trump all the other ancillary techniques for this group of neoplasms. This review therefore emphasizes the key morphologic features required to diagnose and distinguish uterine mesenchymal tumors from their mimics, with a brief description of the relevant immunohistochemical features.

    2006-11-07

    Despite some notable successes cancer remains, for the most part, a seemingly intractable problem. There is, however, a growing appreciation that targeting the tumor epithelium in isolation is not sufficient as there is an intricate mutually sustaining synergy between the tumor epithelial cells and their surrounding stroma. As the details of this dialogue emerge, new therapeutic targets have been proposed. The FDA has already approved drugs targeting microenvironmental components such as VEGF and aromatase and many more agents are in the pipeline. In this article, we describe some of the 'druggable' targets and processes within the tumor microenvironment and review the approaches being taken to disrupt these interactions.

    To study the role of Th2-attracting chemokines in opsoclonus-myoclonus syndrome (OMS), a serious neurological paraneoplastic disorder in need of better immunological understanding and therapy. The CCR4 agonists CCL22 and CCL17 were measured in serum by ELISA in children with OMS (238 and 260, respectively), pediatric controls (115 and 143), and other inflammatory neurological disorders (33 and 24). Both CCL22 (+55 %) and CCL17 (+121 %) were significantly elevated in untreated OMS compared to controls and inter-correlated (p OMS also were higher than in OIND (21 %, 41 %). The concentration of CCL22 in ACTH and steroids groups (not IVIg) was 51 % lower than in controls, but only a smaller effect of ACTH on CCL17 was found. Prospective longitudinal studies revealed a precipitous 81 % drop in CCL22 even by the first week of high-dose ACTH therapy, staying below control mean for at least 12 weeks, and a 34 % reduction after 8 months of combined treatment. Response to ACTH was dose-related (r = -0.50, p OMS. Marked and rapid reduction in CCL22, not CCL17, with either ACTH or steroid therapy suggests differential regulation and cellular sources of CCR4 ligands, and CCL22 as a potential candidate biomarker for ACTH or corticosteroid effect.

  18. Tumor-Associated Macrophages and Neutrophils in Tumor Microenvironment

    Directory of Open Access Journals (Sweden)

    Jaehong Kim

    2016-01-01

    Full Text Available Distinct tumor microenvironment forms in each progression step of cancer and has diverse capacities to induce both adverse and beneficial consequences for tumorigenesis. It is now known that immune cells can be activated to favor tumor growth and progression, most probably influenced by the tumor microenvironment. Tumor-associated macrophages and tumor-associated neutrophils can exert protumoral functions, enhancing tumor cell invasion and metastasis, angiogenesis, and extracellular matrix remodeling, while inhibiting the antitumoral immune surveillance. Considering that neutrophils in inflammatory environments recruit macrophages and that recruited macrophages affect neutrophil functions, there may be various degrees of interaction between tumor-associated macrophages and tumor-associated neutrophils. Platelets also play an important role in the recruitment and regulation of monocytic and granulocytic cells in the tumor tissues, suggesting that platelet function may be essential for generation of tumor-associated macrophages and tumor-associated neutrophils. In this review, we will explore the biology of tumor-associated macrophages and tumor-associated neutrophils and their possible interactions in the tumor microenvironment. Special attention will be given to the recruitment and activation of these tumor-associated cells and to the roles they play in maintenance of the tumor microenvironment and progression of tumors.

    Aside from imaging techniques several (radio-)immunological analyses are used for tumor diagnosis. Oncofetal antigens, for instance the carcinoembryonic antigen (CEA) and alpha-fetoprotein (AFP), have become the most important substances for many malignancies. However, nearly all of the so-called tumor markers are not suitable for early diagnosis or screening either because of low sensitivity or low tumor specifity. On the other hand follow-up measurements give a very sensitive index of the success of treatment and may indicate tumor progression when other signs are still not present. In some carcinomas and under some clinical circumstances tumorspecific markers are available and mandatory for detection and/or staging: AFP in hepatoma, acid phosphatase in metastasizing carcinoma of the prostate and serum thyreoglobulin in differentiated thyroid cancer.

    2014-11-01

    Full Text Available Gastrointestinal stromal tumors are the most frequent mesenchymal tumors of the gastrointestinal tract. The discovery that these tumors, formerly thought of smooth muscle origin, are indeed better characterized by specific activating mutation in genes coding for the receptor tyrosine kinases CKIT and PDGFRA and that these mutations are strongly predictive for the response to targeted therapy with receptor tyrosine kinase inhibitors has made GISTs the typical example of the integration of basic molecular knowledge in the daily clinical activity. The information on the mutational status of these tumors is essential to predict (and subsequently to plan the therapy. As resistant cases are frequently wild-type, other possible oncogenic events, defining other entities, have been discovered (e.g. succinil dehydrogenase mutation/dysregulation, insuline growth factor expression, mutations in the RAS-RAF-MAPK pathway. The classification of disease must nowadays rely on the integration of the clinico-morphological characteristics with the molecular data.

    The high mortality rate associated with cancer and its resistance to conventional treatments such as radiation and chemotherapy has led to the investigation of a variety of anti-cancer immunotherapies. The development of novel immunotherapies has been bolstered by the discovery of tumor-associated antigens (TAAs), through gene sequencing and proteomics. One such immunotherapy employs established allogeneic human cancer cell lines to induce antitumor immunity in patients through TAA presentation. Allogeneic cancer immunotherapies are desirable in a clinical setting due to their ease of production and availability. This review aims to summarize clinical trials of allogeneic tumor immunotherapies in various cancer types. To date, clinical trials have shown limited success due potentially to extensive degrees of inter- and intra-tumoral heterogeneity found among cancer patients. However, these clinical results provide guidance for the rational design and creation of more effective allogeneic tumor immunotherapies for use as monotherapies or in combination with other therapies.

One of the major challenges still facing the field is the heterogeneous distribution of these agents in tumors when administered systemically. Large regions of untargeted cells can therefore escape therapy and potentially select for more resistant cells.

    Full Text Available Childhood adrenocortical tumors (ACT are rare. In the USA, only about 25 new cases occur each year. In Southern Brazil, however, approximately 10 times that many cases are diagnosed each year. Most cases occur in the contiguous states of São Paulo and Paraná. The cause of this higher rate has not been identified. Familial genetic predisposition to cancer (p53 mutations and selected genetic syndromes (Beckwith-Wiedemann syndrome have been associated with childhood ACT in general but not with the Brazilian counterpart. Most of the affected children are young girls with classic endocrine syndromes (virilizing and/or Cushing. Levels of urinary 17-ketosteroids and plasma dehydroepiandrosterone sulfate (DHEA-S, which are abnormal in approximately 90% of the cases, provide the pivotal clue to a diagnosis of ACT. Typical imaging findings of pediatric ACT consist of a large, well-defined suprarenal tumor containing calcifications with a thin capsule and central necrosis or hemorrhage. The pathologic classification of pediatric ACT is troublesome. Even an experienced pathologist can find it difficult to differentiate carcinoma from adenoma. Surgery is the single most important procedure in the successful treatment of ACT. The role of chemotherapy in the management of childhood ACT has not been established although occasional tumors are responsive to mitotane or cisplatin-containing regimens. Because of the heterogeneity and rarity of the disease, prognostic factors have been difficult to establish in pediatric ACT. Patients with incomplete tumor resection or with metastatic disease at diagnosis have a dismal prognosis. In patients with localized and completely resected tumors, the size of the tumor has predictive value. Patients with large tumors have a much higher relapse rate than those with small tumors.

    Full Text Available Neuroendocrine cells are dispersed around the body and can be found within the gastrointestinal system, lungs, larynx, thymus, thyroid, adrenal, gonads, skin and other tissues. These cells form the so-called ''diffuse neuroendocrine system'' and tumors arising from them are defined as neuroendocrine tumors (NETs. The traditional classification of NETs based on their embryonic origin includes foregut tumors (lung, thymus, stomach, pancreas and duodenum, midgut tumors (beyond the ligament of Treitz of the duodenum to the proximal transverse colon and hindgut tumors (distal colon and rectum. NETs at each site are biologically and clinically distinct from their counterparts at other sites. Symptoms in patients with early disease are often insidious in onset, leading to a delay in diagnosis. The majority of these tumors are thus diagnosed at a stage at which the only curative treatment, radical surgical intervention, is no longer an option. Due to the increasing incidence and mortality, many studies have been conducted in order to identify risk factors for the development of NETs. Still, little is known especially when it comes to preventable risk factors such as smoking. This review will focus on smoking and its contribution to the development of different subtypes of NETs.

  12. Föräldrar och förskolans matematik : En enkätundersökning om föräldrars inställning och uppfattning om matematik på förskolan

    Enligt Lpfö-98 skall man på förskolan arbeta med att barnen utvecklar sin förmåga att upptäcka och använda matematik i meningsfulla sammanhang. Jag tror att en förutsättning för en lyckad förskoleverksamhet är att man har föräldrarnas stöd och intresse i de aktiviteter som förekommer och har därför genom enkäter undersökt hur föräldrar uppfattar matematik i förskolan, viken inställning de har, samt deras eventuella tankar om utformningen. Detta har jämförts med den aktuella förskolans tankar ...

    Full Text Available Artikkelen fokuserer på elevenes egne opplevelser omkring sangaktiviteter i skolens musikkopplæring. Sang i skolen drøftes i lys av de rammene vi finner i ”Læreplanverket for Kunnskapsløftet” (LK06. Et sentralt spørsmål vil være om elever i ulike aldre forteller om endring av musikkaktiviteter i takt med et utvidet register i faget. Jeg vil i tillegg diskutere i hvilken grad elevens stemme vil kunne bringe fram ny viten om musikkfaget. Artikkelen er tredelt. Først beskrives målet med studien og begrunnelser for valg av metode. Deretter presenteres resultater fra empirien basert på kvalitative data fra elevintervjuer. I den tredje delen tar drøftingen utgangspunkt i de funn jeg gjorde i min studie.

    Five secondary effluents and a river water source were characterized using size exclusion chromatography (LC-OCD-UVD-OND) and emission-excitation matrix (EEM) fluorescence spectroscopy in order to identify the major effluent organic matter (EfOM) fractions responsible for membrane fouling. This study showed the feasibility of coupling fluorescence EEM and LC-OCD-UVD-OND to investigate the fouling potential as well as a means to differentiate natural organic matter (NOM) from EfOM. The secondary effluents and river water showed a significant difference in organic matter characteristics and fouling potential, highlighting the importance of biological processes and the feed water source on EfOM characteristics and fouling potential. On the basis of statistical analysis, protein-like substances were found to be highly correlated to the fouling potential of secondary effluents. © 2012 Elsevier Ltd.

    I undersøgelser gennemført af Transparency International Danmark i 2014 og 2016 af de største danske børsnoterede og ikke børsnoterede virksomheder viser det sig, at disse virksomheder er meget informative omkring deres procedure for at undgå korruption og bestikkelse samt i deres information om...... ejerforhold. Til gengæld er de store virksomhederne ikke særligt informative om deres omsætning og skattebetaling mv. fordelt på lande. Over tid viser de to undersøgelser, at de største danske virksomheder er blevet mere informative og sammenlignet med tilsvarende undersøgelser udført af Transparency...

  18. Uten lovlig opphold = uten rettigheter? Tilværelsen til migranter uten oppholdstillatelse i lys av normativ teori om rettferdighet

    Full Text Available Migranter som fortsetter å oppholde seg i et land etter avslag på søknad om opphold, eller som unnlater å søke om oppholdstillatelse, utfordrer det juridiske rammeverket for nasjonalstater og statsborgerskap. I denne artikkelen diskuteres livssituasjonen til migranter uten lovlig opphold opp mot normativ kosmopolitisk teori om universelle rettigheter. Dette er belyst i internasjonal litteratur, men i mindre grad innenfor en norsk kontekst. Vi tar i denne artikkelen for oss tre empiriske eksempler: tilværelsen i såkalte ventemottak, tilværelsen utenfor ventemottakene og tilværelsen for barn uten lovlig opphold. Gjennom eksemplene diskuterer vi rettighetsspørsmål i migrantenes liv. Vi viser hvordan menneskerettighetene ikke er tilstrekkelige for å ivareta migrantenes velvære, og hvordan rettigheter migrantene faktisk har, ikke fremstår som reelle fordi det oppleves som risikabelt å benytte seg av dem. Artikkelen setter normativ kosmopolitisk teori i perspektiv ved å diskutere den konkrete situasjonen til migrantene, og spør til slutt hva som kan være konsekvensene av at rettigheter blir ulikt fordelt?Nøkkelord: rettferdighet, rettigheter, migrasjon, ulovlig opphold, kosmopolitismeEnglish summary: Without legal residency = no rights? A discussion of the situation of migrants who have settled without official authorisation, in light of the normative theory of justiceMigrants who continue to reside in a country after having received a negative answer to their residence application, or who stay without registering themselves in the first place, challenge the legal framework of national states and citizenship. In this article, we illustrate the situation of migrants without legal residence in light of normative cosmopolitan theory focusing on the universality of rights. We discuss three empirical contexts: life in the so-called waiting reception centers, life outside the waiting reception centers, and the situation of children

    Flow cytometric cerebrospinal fluid (CSF) lymphocyte subset analysis has improved the diagnosis of neuroinflammation and identified multiple markers of inflammation in opsoclonus-myoclonus syndrome (OMS). The aim of this exploratory, retrospective study was to analyze the effect of immunotherapy on these markers to determine which agents are disease modifying. Cross-sectional immunological observations were made in an IRB-approved case-control study, and patients were treated empirically. Ten different CSF lymphocyte subpopulations from 18 children with persistent OMS had been measured by flow cytometry before and after clinical treatment with cyclophosphamide/ACTH/IVIG combination (n = 7) or ACTH/IVIG alone (n = 11). Clinical severity of OMS was scored from videotapes by a blinded observer using the OMS Evaluation Scale. Only cyclophosphamide combination therapy (mean dose 26 ± 3 mg/kg or 922 ± 176 mg/m 2 x 6 cycles) significantly decreased the percentage of CSF B cells. The mean reduction was 65%, with CSF B cell frequency normalized at 7-8 months in 70%. Other abnormalities of the CSF immunophenotype, such as the low CD4/CD8 T cell ratio, persisted, and there were no therapeutic changes in T cell activation/maturation markers. Effects on relative and absolute size of PBMC subsets were similar. Clinical improvement was 70% and 55% in respective treatment groups. The relapse rates of the two groups did not significantly differ. The main effect of cyclophosphamide combination therapy on neuroinflammation in OMS was moderate reduction in CSF B cell expansion. Though exploratory, it may provide a steroid sparer option in partially-responsive OMS. Copyright © 2018 European Paediatric Neurology Society. Published by Elsevier Ltd. All rights reserved.

    An evaluation test to investigate the behavior of the Oxygen to Metal ratio (O/M ratio) drift and its effect to material accounting in Feed preparation process was carried out in operational MOX fuel fabrication process, Plutonium Fuel Production Facility (PFPF) of Power Reactor and Nuclear Fuel Development Corporation (PNC). The test results clearly show the transition of O/M ratio along the Feed preparation process flow and it was increased gradually according to the progress of process steps. It leveled off after Feed lot blending operation and then it remained stable around 2.25. Analytical result of plutonium concentration after the correction with the changes of moisture concentration on the same sample as O/M ratio analysis has strong correlation with O/M ratio result as the theory. Therefore, it was confirmed that the plutonium concentration of the MOX should be corrected on the basis of the changes in O/M ratio and moisture concentration. Sample taking after blending operation was carried out at Cross Blending process step. An analysis of variance for plutonium concentration using two-way layout, whose factors are feed blending batch (factor A) and container (factor B), is carried out. Since no significant difference was observed in factor A nor B, the test concludes that a sample taken after blending operation can be considered as representative for the whole material blended by cross blending operation. Now the software of 'Material Accounting System' is being modified to improved one, that is, the plutonium concentration after the intermediate storage and after treatment in a process glove box is corrected with the change of O/M ratio and moisture concentration.
