    Fosamprenavir, a Vertex Pharmaceuticals phosphate ester prodrug of the HIV protease inhibitor amprenavir, is under development by GlaxoSmithKline (GSK; formerly Glaxo Wellcome) for the potential treatment of HIV infection in adults and children. By November 2000, it was in phase III trials; a third phase III trial was initiated in April 2001. In October 2001, GSK expected filing in both the EU and US in 2002. In January 2002, Vertex anticipated an NDA filing during the second half of 2002. Fast-track status for fosamprenavir was received by Glaxo Wellcome in December 1999. As of January 2002, enrollment was complete for two of the three phase III trials, and an NDA was expected to be filed during 2002. Fosamprenavir was first synthesized at Vertex as part of a collaboration with Glaxo Wellcome and by 1999, it was being developed by Glaxo Wellcome as part of an ongoing agreement between the two companies. In September 2000 and January 2001, Merrill Lynch predicted a 2002 launch, with sales of pounds sterling 50 million in 2002, rising to pounds sterling 150 million in 2004. PMID:12054084

    2014-01-01

    In May 2013, GlaxoSmithKline (980 Great West Road, Brentford, Middlesex, TW8 9GS, UK) established a new online system to enable scientific researchers to request access to anonymised patient level clinical trial data. Providing access to individual patient data collected in clinical trials enables conduct of further research that may help advance medical science or improve patient care. In turn, this helps ensure that the data provided by research participants are used to maximum effect in the creation of new knowledge and understanding. However, when providing access to individual patient data, maintaining the privacy and confidentiality of research participants is critical. This article describes the approach we have taken to prepare data for sharing with other researchers in a way that minimises risk with respect to the privacy and confidentiality of research participants, ensures compliance with current data privacy legal requirements and yet retains utility of the anonymised datasets for research purposes. We recognise that there are different possible approaches and that broad consensus is needed. PMID:24668938

    2000-04-01

    Zanamivir, a neuraminidase inhibitor under license from Biota, has been developed and launched by Glaxo Wellcome for the treatment of influenza virus infection [277127]. While registered as drugs, neuraminidase inhibitors are technically vaccines as they are believed to work by provoking an immune response, thus preventing the spread of infection from one cell to another within the respiratory tract [314356]. It is administered, using an inhaler, directly to where the virus replicates, minimizing the potential for side effects. Zanamivir has been launched, under the name Relenza, for the treatment of influenza in Australia [325148], New Zealand [335591] and the UK [341871]. It is registered in Mexico and Armenia [346474], and approved in Japan [351580]. In October 1999, it was launched in the US [352392] and Glaxo confirmed in January 2000, that zanamivir has been launched all over Europe, with the exception of Greece and Spain, where launch is imminent [352513]. In October 1999, the British Pharma Group (BPG) wrote to the UK Prime Minister to seek a discussion on the implications for the British-based pharmaceutical industry of the recommendation from NICE's Raised Appraisal Committee that Relenza should be banned from the NHS [342597]. An FDA submission was made in October 1998 [302732,304779]; the FDA advisory committee met on February 24 1999 to discuss the application [313583]. The Antivirals Drugs Advisory Committee voted against recommending zanamivir for FDA approval [316196]. Members suggested that additional studies using a different endpoint or targeting specific high-risk populations would be more likely to garner support [317454]. Following a discussion with Glaxo Wellcome in April 1999, the FDA indicated that it would continue to review the NDA for zanamivir [320565]. In July 1999, the company received final FDA approval for the drug for the treatment of both influenza A and B [334127], and aimed to initiate a phase IV trial program for the detection of consumer problems with the product, following launch of the product in time for the 1999-2000 flu season [352392,335048]. In September 1998, Glaxo applied to the Canadian Health Protection Branch (HPB) for approval to market zanamivir for the treatment and prevention of influenza. A separate application for Fast Track approval was also made with the HPB [299375,299472]. In November 1999, zanamivir received approval in Canada [346474]. Glaxo expects to make MAA and NDA filings for the use of zanamivir as a prophylactic in 1999 [333494]. In July 1998, Merrill Lynch predicted that as zanamivir offered only modest benefits gained from a narrow treatment window, potential would be limited and forecast annual sales of US dollar 30 million [302048]. In January 1999, Paribas predicted sales of pounds 75 million in 1999, rising to pounds 280 million in 2003 [317650]. In April 1999, ABN Amro predicted sales of pounds 23 million in 1999, rising to pounds 326 million in 2003 [328676]. In August 1999, Lehman Brothers estimated that sales of zanamivir will reach US dollar 400 million by 2003, and that it is an obvious candidate for an OTC switch, although this is not likely until 5 years after launch [336356].

    2013-05-01

    A quadrivalent meningococcal serogroup A, C, W and Y conjugate vaccine (ACWY), utilising tetanus toxoid (TT) as its carrier protein (ACWY-TT; Nimenrix, GlaxoSmithKline Vaccines, Rixensart, Belgium) has been demonstrated to be safe and immunogenic when administered to young children from 12 months of age, older children, adolescents, and adults. Administration of a single dose of ACWY-TT induces protective serum bactericidal antibodies against all four serogroups as well as good antibody persistence. Coadministration studies have demonstrated that ACWY-TT can be administered with diphtheria, tetanus, three-component acellular pertussis, hepatitis B, inactivated polio virus and Haemophilus influenzae type b conjugate vaccine (DTaP3-IPV-HBV/Hib, Infanrix hexa; GlaxoSmithKline Vaccines, Rixensart, Belgium); measles, mumps, rubella, varicella vaccine (Priorix-Tetra; GlaxoSmithKline Vaccines, Rixensart, Belgium); 10-valent pneumococcal conjugate vaccine (Synflorix(); GlaxoSmithKline Vaccines, Rixensart, Belgium); hepatitis A and B vaccine (Twinrix(); GlaxoSmithKline Vaccines, Rixensart, Belgium); and seasonal influenza vaccine (Fluarix; GlaxoSmithKline Vaccines, Rixensart, Belgium). Studies in young infants from 2 months of age have now commenced but immunisation with a single dose of ACWY-TT from 12 months of age is a safe and immunogenic option in the prevention of meningococcal disease.

    1977-01-01

    Microphotometry of calcium K-line photographs in the regions of polar coronal holes shows that the chromospheric network exterior to a hole has a slightly broader intensity distribution than that inside the hole itself, a fact which can be attributed to a greater number of bright network elements outside the hole. These bright elements presumably represent the enhanced network resulting from the dispersal of magnetic flux from old active regions, a hypothesis which is consistent with current ideas of coronal-hole formation.

  15. Stephen Jay Kline on systems, or physics, complex systems, and the gap between.

    SciTech Connect

    Campbell, Philip LaRoche

    2011-06-01

    At the end of his life, Stephen Jay Kline, longtime professor of mechanical engineering at Stanford University, completed a book on how to address complex systems. The title of the book is 'Conceptual Foundations of Multi-Disciplinary Thinking' (1995), but the topic of the book is systems. Kline first establishes certain limits that are characteristic of our conscious minds. Kline then establishes a complexity measure for systems and uses that complexity measure to develop a hierarchy of systems. Kline then argues that our minds, due to their characteristic limitations, are unable to model the complex systems in that hierarchy. Computers are of no help to us here. Our attempts at modeling these complex systems are based on the way we successfully model some simple systems, in particular, 'inert, naturally-occurring' objects and processes, such as what is the focus of physics. But complex systems overwhelm such attempts. As a result, the best we can do in working with these complex systems is to use a heuristic, what Kline calls the 'Guideline for Complex Systems.' Kline documents the problems that have developed due to 'oversimple' system models and from the inappropriate application of a system model from one domain to another. One prominent such problem is the Procrustean attempt to make the disciplines that deal with complex systems be 'physics-like.' Physics deals with simple systems, not complex ones, using Kline's complexity measure. The models that physics has developed are inappropriate for complex systems. Kline documents a number of the wasteful and dangerous fallacies of this type.

    We welcome Kline's attempt to develop an overarching framework to allow much needed collaboration between fields in the study of teaching. While we see much utility in this enterprise, we are concerned that there is too much focus on the behavior of the teacher, without examining results or costs, and the categories within the framework are not sufficiently distinct.

  17. Making British cortisone: Glaxo and the development of corticosteroids in Britain in the 1950s-1960s.

    PubMed

    Quirke, Viviane

    2005-12-01

    Following the announcement in 1949 in the USA that cortisone offered rheumatoid arthritis sufferers effective treatment for their crippling disease, the Ministry of Health came under considerable pressure from the medical profession and the public to make cortisone available in Britain. The Ministry, therefore, urged British companies to start manufacturing cortisone. Among the several pharmaceutical firms responding to the Ministry's request, Glaxo's expertise in the field of vitamins gave them a head start. This paper describes the varied and flexible strategy that enabled Glaxo to maintain this head start, and the scientific and technical capabilities which the company subsequently built up, enabling them to dominate the market for corticosteroids in Britain. Among the drugs to emerge out of the Glaxo project to manufacture cortisone, which began in 1950 and later became a wider R&D programme on steroids, was the topical steroid Betnovate, launched in 1963, which remains a best-seller today. However, although it led to successful new products, Glaxo's programme had limitations. The paper identifies a missed opportunity, in the shape of the biosynthetic route to steroid drugs, often considered as a milestone in the development of the new biotechnology. Whether or not this missed opportunity proved costly to the company is uncertain. However, it illustrates the role of technological path-dependence, and the importance of the integration between different scientific disciplines, in this case chemistry and biology, in pharmaceutical innovation.

    In this report we comment on the relationship between the Lyman alpha and Calcium K-line emission from the Sun. We firstly examine resolved Lyman alpha images (from TRACE) and resolved K-line images. We find that the Lyman alpha emission is consistent with a linear dependence on the K-line emission. As this is in conflict with the analysis of Johannesson et al.(1995, 1998) we proceed by comparing the disk integrated Lyman alpha flux as a function of ratio between the disk integrated Mg II core and wing fluxes (Johannesson et al (1998) having previously found a linear dependence between this index and the BBSO K-line index). We find that a reasonably good fit can be obtained, however note the discrepancies which lead Johannesson et al to consider the square root relationship. We suggest an alternative interpretation of the discrepancy.

  19. Simplified Katsevich algorithm motivated by the distribution properties of k-lines

    The Katsevich algorithm is a breakthrough in the theoretically exact algorithms for helical cone beam computed tomography (CT). For future application in medical and industrial CT, determining how to implement it efficiently and accurately is the main task. We analyzed the slope law and intersection law of the k-lines, finding that the k-lines are not intersecting if the half-maximal fan angle (HMFA) is <21 deg (numerical solution, so it is approximate) and that the helical pitch and HMFA determine the depth of parallelism of k-lines. Using an appropriate pitch and an HMFA that is <21 deg, one can use a simplified Katsevich algorithm, whose filtration process can be done on the rows of the detector panel so that the preweighting, pre-rebinning, post-rebinning, and postweighting steps are all canceled. Simulation experiments show that the simplified algorithm can obtain highly precise images at a faster speed. Our results are intended to be valuable to those who are working on efficient implementations of the Katsevich-type algorithms.

  20. Natural product source material use in the pharmaceutical industry: the Glaxo experience.

    PubMed

    Turner, D M

    1996-04-01

    Glaxo PLC has had a significant involvement with Natural Product Source Materials for all of its commercial history and, most recently, has pursued this interest by use of such materials as templates for new lead discovery. Through the expertise and facilities in its Natural Products Discovery Department, Glaxo extracts relatively small quantities of plant material (typically 200-250 g dry weight) and cultures microorganisms from environmental samples (typically 10-50 g). Extracts and fermentation broths are screened in order to detect bioactive principles (BPs). If the potency, selectivity and specificity of the BP is acceptable, isolation, purification and structural elucidation follows. It is most unlikely, in our experience, that the BP itself will become a drug; it is much more likely that we shall need to initiate a medicinal chemistry synthesis program in order to try to produce a molecule that has both the essential biological and desirable chemical properties to become a drug development candidate. This synthetic process is often a long one and our confidence that such a process is worth undertaking is greatly improved if the BP is novel. An essential component of any medicinal chemistry strategy is that it allows us to obtain secure intellectual property rights through patents. Acquisition of product claim protection, the strongest form of patent protection, is of great importance. Safety testing and clinical development of the candidate drug can take 7-10 years, and often more, during which patent protection is constantly eroding. Recognizing that acquisition of Natural Products Source Materials is an issue of growing concern, Glaxo Research and Development Ltd. (GRD), in the early part of 1992, implemented a policy for plant supply. This policy was subsequently modified to embrace source materials such as environmental, soil and marine samples from which fungi, micro- and microorganisms may be obtained. As a direct consequence of this policy, Natural Product Source Materials supply agreements are only concluded with national and international organizations who possess the expertise to identify and collect the samples. It is equally important that our suppliers have the authority, which must be provided to GRD in writing, to collect such materials and to provide them to GRD for extraction and screening purposes. Such materials must be from sustainable and accessible sources. We will not seek to collect any endangered species. Though ethnomedical information can be helpful, it is not essential. Plants must be taxonomically classified. We reimburse the supplying institute for their efforts and their expertise, and recognize an obligation to offer a royalty to the institute in the event that drug discovery, with subsequent commercialization, owes its origin, however indirectly, to a material that it provided. In discussions with the institute, we insist that "a fair proportion' (>40%) of that royalty be used for the direct benefit of the people in the collection source area. In this context, GRD recognizes the importance of local training and education. PMID:9213629

    2012-02-01

    Transuranic nuclides have been released into the environment since the beginning of the nuclear age. In many of the areas so contaminated, a significant fraction of the plutonium appears under the form of radioactive particles (also called 'hot' particles). In previous works, García López et al. (2007) [1] and Jiménez-Ramos et al. (2010) [2], radioactive particles from aircraft accidents in Palomares and Thule have been characterized. Using micro-Proton Induced X-ray Emission (μ-PIXE) and confocal X-ray fluorescence microprobe (μ-XRF), the L-lines of the main components in these particles, U and Pu, were analyzed. In this work, the key goal is the possibility to determine elemental ratios and concentration of transuranic elements in hot particles from the same areas but using their K-lines, because of their advantages in comparison with the study of L-lines. Indeed, the U and Pu K-lines present not overlapping between the main peaks in the spectra and the X-ray absorption in the sample is much lower than for L-lines.

  8. Solar Cycle Fine Structure and Surface Rotation from Ca II K-Line Time Series Data

    Scargle, Jeff; Keil, Steve; Worden, Pete

    2011-01-01

    Analysis of three and a half decades of data from the NSO/AFRL/Sac Peak K-line monitoring program yields evidence for four components to the variation: (a) the solar cycle, with considerable fine structure and a quasi-periodicity of 122.4 days; (b) a stochastic process, faster than (a) and largely independent of it, (c) a quasi-periodic signal due to rotational modulation, and of course (d) observational errors (shown to be quite small). Correlation and power spectrum analyses elucidate periodic and aperiodic variation of these chromospheric parameters. Time-frequency analysis is especially useful for extracting information about differential rotation, and in particular elucidates the connection between its behavior and fine structure of the solar cycle on approximately one-year time scales. These results further suggest that similar analyses will be useful at detecting and characterizing differential rotation in stars from stellar light-curves such as those being produced at NASA's Kepler observatory.

  9. Adam Smith and dependency.

    PubMed

    Ozler, Sule

    2012-06-01

    The focus of this paper is the works and life of Adam Smith, who is widely recognized as the father and founder of contemporary economics. Latent content analysis is applied to his seminal text in economics, An Inquiry into the Nature and Causes of the Wealth of Nations (1776). The results reveal that Smith considers dependence on others a problem and sees the solution to this problem in impersonalized interdependence. In addition, his views on social dependency and personal dependency, reflected in his Lectures on Jurisprudence (1963) and The Theory of Moral Sentiments (1759), are analyzed. This analysis suggests a central tension between dependence and independence in Smith's writings. The personal dependency patterns he exhibited in his life, which also suggest a tension between dependence and independence, are identified through a reading of his biographies. Based on insights from psychoanalytic literature, this paper proposes that developing the ideas in the Wealth of Nations was part of Smith's creative solution to this tension. In particular, his solution to one individual's dependence on another was through a system of impersonalized interdependence. In other words, Smith defended against his personal dependence through his economic theorizing. PMID:22712591

    The characteristic K-line yields Y(E₀) of a pure thick titanium (Z=22) element target are measured for 8-18 keV electron impact and compared with the simulation calculations using PENELOPE code. A fair agreement between experiment and simulation results is found within the existing experimental uncertainty of measurements. The ratio F of indirectly produced characteristic Ti K X-ray yield to its total (directly+indirectly) yield is determined by employing an approximate analytical formulation of Hanson and Cowan (Hanson, H.P., Cowan, D.J., 1961. Phys. Rev. 124, 22-26). It is found that F changes strongly with impact energy E₀ for normal angle of incidence in contrast to a mild change predicted by the simulation calculations. Furthermore, experimental and simulation results for peak to effective continuum ratio R of Ti K-line are compared and discussed for the energy range of impact of the present investigation.

He had taught in universities in the United States and Turkey, and he had worked as an engineer in the field of hydrology in the United States. Somehow, a chance meeting with John Adam Fleming, AGU's long-time General Secretary, led to Waldo's becoming the first executive officer employed by the Union. That, in turn, brought him the opportunity to make a difference.

    Analysis of over 36 yr of time series data from the NSO/AFRL/Sac Peak K-line monitoring program elucidates 5 components of the variation of the 7 measured chromospheric parameters: (a) the solar cycle (period {approx} 11 yr), (b) quasi-periodic variations (periods {approx} 100 days), (c) a broadband stochastic process (wide range of periods), (d) rotational modulation, and (e) random observational errors, independent of (a)-(d). Correlation and power spectrum analyses elucidate periodic and aperiodic variation of these parameters. Time-frequency analysis illuminates periodic and quasi-periodic signals, details of frequency modulation due to differential rotation, and in particular elucidates the rather complex harmonic structure (a) and (b) at timescales in the range {approx}0.1-10 yr. These results using only full-disk data suggest that similar analyses will be useful for detecting and characterizing differential rotation in stars from stellar light curves such as those being produced by NASA's Kepler observatory. Component (c) consists of variations over a range of timescales, in the manner of a 1/f random process with a power-law slope index that varies in a systematic way. A time-dependent Wilson-Bappu effect appears to be present in the solar cycle variations (a), but not in the more rapid variations of the stochastic process (c). Component (d) characterizes differential rotation of the active regions. Component (e) is of course not characteristic of solar variability, but the fact that the observational errors are quite small greatly facilitates the analysis of the other components. The data analyzed in this paper can be found at the National Solar Observatory Web site http://nsosp.nso.edu/cak{sub m}on/, or by file transfer protocol at ftp://ftp.nso.edu/idl/cak.parameters.

  14. Absence epileptic activity changing effects of non-adenosine nucleoside inosine, guanosine and uridine in Wistar Albino Glaxo Rijswijk rats.

    Adenosine (Ado) and non-adenosine (non-Ado) nucleosides such as inosine (Ino), guanosine (Guo) and uridine (Urd) may have regionally different roles in the regulation of physiological and pathophysiological processes in the central nervous system (CNS) such as epilepsy. It was demonstrated previously that Ino and Guo decreased quinolinic acid (QA)-induced seizures and Urd reduced penicillin-, bicuculline- and pentylenetetrazole (PTZ)-induced seizures. It has also been demonstrated that Ino and Urd may exert their effects through GABAergic system by altering the function of GABA(A) type of gamma-aminobutyric acid receptors (GABAA receptors) whereas Guo decreases glutamate-induced excitability through glutamatergic system, which systems (GABAergic and glutamatergic) are involved in pathomechanisms of absence epilepsy. Thus, we hypothesized that Ino and Guo, similarly to the previously described effect of Urd, might also decrease absence epileptic activity. We investigated in the present study whether intraperitoneal (i.p.) application of Ino (500 and 1000mg/kg), Guo (20 and 50mg/kg), Urd (500 and 1000mg/kg), GABA(A) receptor agonist muscimol (1 and 3mg/kg), GABA(A) receptor antagonist bicuculline (2 and 4mg/kg), non-selective Ado receptor antagonist theophylline (5 and 10mg/kg) and non-competitive N-methyl-d-aspartate (NMDA) receptor antagonist (+)-5-methyl-10,11-dihydro-5H-dibenzo (a,d) cyclohepten-5,10-imine maleate (MK-801, 0.0625 and 0.1250mg/kg) alone and in combination have modulatory effects on absence epileptic activity in Wistar Albino Glaxo Rijswijk (WAG/Rij) rats. We found that Guo decreased the number of spike-wave discharges (SWDs) whereas Ino increased it dose-dependently. We strengthened that Urd can decrease absence epileptic activity. Our results suggest that Guo, Urd and their analogs could be potentially effective drugs for treatment of human absence epilepsy. PMID:26037802

  17. Simulations of Zeeman-split CA II K-line Stokes profiles with angle-dependent partial redistribution.

    1997-09-01

    The formulation of the polarized radiative transfer equations for Zeeman-split spectral lines is still incomplete for cases with frequency-dependent line source function, e.g. when partial frequency distribution (PRD) of line photons occurs (strong resonance lines). Under the well-founded assumption that the field-free approximation works equally well for lines with partial redistribution as for lines with complete redistribution (CRD), we decouple the computation of the level populations (accounting for PRD effects) from the formal Stokes vector solution. The level populations are obtained with the Hubeny & Lites (1995ApJ...455..376H) version of Carlsson's (1986UppOR..33....1C) MULTI code, and the formal solution follows by means of a modified version of the Murphy & Rees (1990, NCAR Technical Note NCAR/TN-348+IA) SPSR code. Due to lack of the appropriate equations concerning the combination of partial redistribution and Zeeman splitting of spectral lines, an ad hoc partial redistribution approach (basically allowing for wavelength dependence of the line source function) is implemented in the SPSR code. This combination of codes is used to study the relevance of partial redistribution to the Caii K-line diagnostics of solar plage regions using grids of flux-tube models. In addition to magnetic fields, velocity fields play an important role in the formation of the K-line profiles, but these invalidate the commonly-used angle-averaged PRD formalism. We therefore extended the Hubeny & Lites (1995ApJ...455..376H) angle-averaged PRD version of MULTI code to the angle-dependent case, which allows line profiles to be computed under PRD conditions for arbitrary (but not too large) velocity fields. This code is subsequently used to perform the non-magnetic non-LTE statistical equilibrium computations for a few schematic velocity structures in plage flux tubes and in the surrounding non-magnetic atmosphere. The SPSR code is again used to obtain the K-line Stokes profiles. We investigate in particular the asymmetry of the K line intensity and circularly polarized profiles produced by the velocity fields.

  18. Smith-Magenis syndrome.

    PubMed

    2013-01-01

    Smith-Magenis syndrome (SMS) is a mental retardation syndrome with distinctive behavioral characteristics, dysmorphic features, and congenital anomalies ascribed to an interstitial deletion of chromosome 17p11.2. Severe sleep disturbances and maladaptive daytime behavior have been linked to an abnormal circadian rhythm of melatonin with a diurnal instead of nocturnal secretion of this hormone. SMS provides a demonstration of a biological basis for sleep disorder in a genetic disease. Considering that clock genes mediate the generation of circadian rhythm, haploinsufficiency for a circadian system gene, mapping to chromosome 17p11.2, may cause the inversion of the melatonin circadian rhythm in SMS. The disorder of circadian timing in SMS may also affect entrainment pathway (retinohypothalamic tract), pacemaker functions (suprachiasmatic nuclei), or synthesis and release of melatonin by the pineal gland. Elucidating pathophysiological mechanisms of behavioral phenotypes in genetic disease can provide an original therapeutic approach in SMS: blockade of endogenous melatonin production during the day combined with exogenous melatonin administration in the evening.

    For some high atomic number atoms, the energy of the K-edge is tens of eVs higher than the K-line energy of another atom, so that a few eV increase in the line's energy results in a decreasing transmission of the x-ray through a filter of the matching material. The transmission of cold iridium's Asymptotically-Equal-To 63.287 keV K{alpha}{sub 2} line through a lutetium filter is 7% lower when emitted by ionized iridium, consistent with an energy increase of {Delta}{epsilon} Asymptotically-Equal-To 10{+-}1 eV associated with the ionization. Likewise, the transmission of the K{beta}{sub 1} line of ytterbium through a near-coincident K-edge filter changes depending on plasma parameters that should affect the ionization. Systematic exploration of filter-line pairs like these could become a unique tool for diagnostics of suitable high energy density plasmas.

    Economically important and hydrothermally formed kaolin deposits are often found within rift lithologic units, formed as a result of interaction of physical and geochemical processes in the extensional environment. The kaolin deposits of Balikesir--Duvertepe, Turkey and Kline Mountain, Sierra County, New Mexico, studied herein, are examples of this type. The Balikesir--Duvertepe district has been known as the most productive kaolin district in Turkey. Total reserves are estimated at 15 million metric tons. Located in the active Simav Graben produced by the subduction of the African Plate under the Aegean region, the kaolin deposits occur irregularly and variably in quality as a result of hydrothermal alteration of Neogene tuffs. The Kline Mountain kaolin deposit was formed as a result of advanced argillic alteration on the southeastern edge of the Mogollon--Datil volcanic field, which is related to the extensional environment of Basin and Range province and the Rio Grande rift. Its reserve is reported as 200 million metric tons of altered tuffs. The two deposits show striking similarities: extensional related rock units, intense in situ hydrothermal alteration, mineral content, seismic activity, alunite contamination, chemical composition, and intense silicification. The deposits also display some differences: regional climate, the intensity of hydrothermal alteration and the elapsed time causing relatively complete replacement in the Turkish deposit compared to that in NM. The Balikesir--Duvertepe district has been the center of kaolin marketing for use chiefly in ceramic, paper, and white cement, while the Kline Mountain kaolin had been exploited primarily for paper and ceramic tile as a coating; and in the oil industry as a filler and absorbent material.

    We showed previously that the number of spike-wave discharges (SWDs) was increased after intraperitoneal (i.p.) injection of lipopolysaccharide (LPS), inosine (Ino) and muscimol alone whereas i.p. guanosine (Guo), uridine (Urd), bicuculline, theophylline and (+)-5-methyl-10,11-dihydro-5H-dibenzo(a,d)cyclohepten-5,10-imine maleate (MK-801) alone decreased the SWD number in Wistar Albino Glaxo/Rijswijk (WAG/Rij) rats. These drugs may exert their effects on absence epileptic activity mainly via proinflammatory cytokines-evoked increase in cortical excitability (such as LPS), GABAergic system (LPS, Ino, Urd, muscimol and bicuculline), glutamatergic system (LPS, Guo and MK-801) and adenosinergic system (LPS, Ino, Guo, Urd and theophylline). Both GABAergic system and glutamatergic system are involved in the pathomechanism of absence epilepsy, the LPS-evoked increase in absence epileptic activity and the pro- or antiepileptic effects of non-adenosine (non-Ado) nucleosides Ino, Guo and Urd. Moreover, Ino, Guo and Urd have modulatory effects on inflammatory processes. Thus, we investigated whether Ino, Guo and Urd have also modulatory influence on LPS-evoked increase in SWD number using two different concentrations of each nucleoside in WAG/Rij rats. We demonstrated that Ino dose-dependently aggravated whereas Guo and Urd attenuated the LPS-evoked increase in SWD number. Our results suggest that different nucleosides have diverse effects on LPS-induced changes in absence epileptic activity. PMID:26365718

    2012-01-01

    Smith-Lemli-Opitz syndrome (SLOS) is a multiple congenital malformation/intellectual disability syndrome, with clinical characteristics encompassing a wide spectrum and great variability. Elucidation of the biochemical and molecular genetic basis for the autosomal recessively inherited SLOS, specifically, understanding SLOS as a cholesterol deficiency syndrome caused by mutations in DHCR7, opened up enormous possibilities for therapeutic intervention. When cholesterol was discovered to be the activator of sonic hedgehog, cholesterol deficiency with inactivation of this developmental patterning gene was thought to be the cause of SLOS malformations, yet this explanation is overly simplistic. Still, despite these important research breakthroughs, there is no proven treatment for SLOS. Better animal models are needed to allow potential treatment testing and the study of disease pathophysiology, which is incompletely understood. Creation of human cellular models will surely be useful, especially models of brain cells. In vivo human studies are essential as well. There have only been limited natural history studies of SLOS to date. Biomarker development will be critical in facilitating clinical trials in this rare condition, since clinical phenotype may change over many years. Additional research in these and other areas is critical if we are to make headway towards ameloriating the effects of this devastating condition. PMID:21777499

    Iodine-131 tositumomab [B1, Bexxar , iodine-131 anti-B1 antibody] is a murine antibody conjugated to iodine 131 that recognises and binds to the B1 (CD20) antigen which is found specifically on B lymphocytes. Iodine-131 tositumomab has a dual mechanism of action. It is capable of initiating a host immune response to those B cells to which it is attached, and it also triggers apoptosis in a significant proportion of the cells to which it binds. The product was first discovered by Coulter Corporation, Miami, in collaboration with the Dana-Farber Cancer Institute and the University of Michigan. The spin-off company Coulter Pharmaceutical, upon its formation, obtained worldwide rights to iodine-131 tositumomab. (Coulter Corporation was acquired subsequently by Beckman Instruments in October 1997. The union of the two companies produced Beckman Coulter.) In December 2000, Coulter Pharmaceutical was acquired by, and merged into, Corixa Corporation.Iodine-131 tositumomab is available for licencing in Japan. Corixa Corporation and GlaxoSmithKline signed an agreement to jointly develop and commercialise iodine-131 tositumomab. The total agreement has a potential value of up to $US132 million, plus shared profits and royalties. The two companies will jointly market the antibody in the US following regulatory approval. Corixa Corporation has announced it expects iodine-131 tositumomab to be approved in the US for non-Hodgkin's lymphoma (NHL). Under the terms of the original agreement, GlaxoSmithKline will receive exclusive marketing rights outside the US, excluding Japan. However, an amended agreement between the two companies will allow Corixa Corporation to also market the product outside the US. In February 2003, the European Commission granted iodine-131 tositumomab orphan-drug designation. Corixa Corporation and GlaxoSmithKline also intend to jointly investigate the use of the product in other indications. GlaxoSmithKline may also receive access to second generation anti-CD20 compounds under its agreement with Corixa Corporation. In May 2003, Corixa Corporation entered into an agreement that will see GlaxoSmithKline market Bexxar in Canada. Under the terms of the agreement, Corixa Corporation will manufacture and supply the product to GlaxoSmithKline, who will register, market and sell it in Canada. In October 2001, Amersham PLC, a supplier of medical equipment, announced that its Amersham Health unit had signed a marketing agreement with Corixa Corporation. The agreement allows Amersham Health to market iodine-131 tositumomab in Europe. Corixa Corporation formed agreements with Boehringer Ingelheim Pharma KG and Lonza Biologics to produce the B1 antibody and radiolabelling of the antibody has been contracted out to MDS Nordion.Iodine-131 tositumomab has received orphan drug and fast track designation for the treatment of NHL. Corixa Corporation submitted a Biologics Licence Application (BLA) to the US FDA in 1999, seeking permission to market Bexxar in the US for the treatment of relapsed or refractory, low grade or transformed low grade B-cell NHL. Following a priority review, the US FDA requested that Corixa Corporation reformat certain sections and perform additional analyses of existing data in its BLA. Corixa Corporation and GlaxoSmithKline resubmitted their BLA to the US FDA in September 2000. The BLA was subsequently accepted by the US FDA in November 2000. However, in March 2001, the US FDA requested additional information in its complete review letter to Corixa Corporation and marketing partner GlaxoSmithKline. The two companies submitted data pertaining to the chemistry, manufacturing and controls section of the BLA, and to the majority of the questions regarding the clinical section of the BLA in August 2001. Corixa Corporation and GlaxoSmithKline submitted the remainder of the response to the US FDA in September 2001, following an independent review of clinical trial data. In March 2002, Corixa Corporation received another complete review letter from the US FDA, which stated that additional clinical trials would have to be conducted in order to provide adequate evidence of the safety and clinical benefit of Bexxa. The US FDA also denied Corixa Corporation's request for accelerated approval, stating that the data provided was inadequate to show that Bexxar filled an unmet medical need. Corixa Corporation has met formally with the US FDA but the two were unable to resolve their differences. Corixa Corporation will now file a formal request for dispute resolution under the Food and Drug Administration Modernisation Act. Corixa Corporation also requested a presentation of Bexxa data to the US FDA's scientific advisors. In June 2002, the US FDA granted the company's appeal for additional regulatory review. In December 2002, the US FDA's Oncologic Drugs Advisory Committee agreed that Bexxar has clinical benefit for patients with NHL. In May 2003, Corixa Corporation and GlaxoSmithKline announced that they had fulfilled many of the steps required for US FDA approval, however the US FDA has extended its review of the application for another 3 months. This extension will allow for further refinement of post marketing commitments and package insert language, and to ensure they are consistent with an updated safety database requested by the US FDA and submitted by Corixa Corporation in early April. GlaxoSmithKline was waiting for the outcome of the situation before deciding on marketing plans for Bexxar. Corixa Corporation and GlaxoSmithKline will conduct a head-to-head study of Bexxar and Idec's Zevalin, planned for mid-2003. The trial will likely be one of three phase IV studies that the US FDA requires for accelerated approval of Bexxar. Corixa Corporation initiated its Expanded Access Program for Bexxar in response to requests from physicians and patients for continued access to Bexxar during the period prior to potential US FDA marketing approval.A phase II multicentre trial of Bexxar in combination with CHOP chemotherapy is underway in the US as first-line therapy in patients with intermediate-grade NHL. Corixa Corporation has initiated a phase II trial of iodine-131 tositumomab in combination with cyclophosphamide, vincristine and prednisone for the treatment of previously untreated low-grade NHL. The trial was initiated while the company was preparing its BLA for Bexxar for use as a single agent for relapsed or refractory NHL. Corixa Corporation intends to pursue additional trials to expand the potential use of iodine-131 tositumomab to other indications, including chronic lymphocytic leukaemia. The agent is also in a clinical trial for preparation in autologous bone marrow transplant patients. The trial is designed to test the combination of iodine-131 tositumomab and chemotherapy. The trial began in 1995 and has so far enrolled 40 patients. In addition, a phase II dose-escalation trial has begun at the University of Nebraska for the combined use of iodine-131 tositumomab and chemotherapy as preparation for autologous bone marrow transplant. Corixa Corporation has received an issued US patent covering methods for administering and dosing radioimmunotherapy for the treatment of B-cell lymphomas. The patent covers iodine-131 tositumomab and other anti-CD20 antibodies used to aid in selective tumour targeting. Corixa Corporation has exclusive rights to the patent.A February 2000 media release from GlaxoSmithKline and Corixa Corporation stated that they had been issued a composition patent relating to radiolabelled monoclonal antibodies (including Bexxar) for the treatment of B-cell lymphomas. On 11 September 2001, IDEC announced that it had filed two separate lawsuits. The first lawsuit is against Corixa Corporation and the University of Michigan on six patents pertaining to products and processes related to radioimmunotherapy. They seek a declaration that Zevalin does not infringe Corixa Corporation's issued US patents. The second lawsuit involves two patents relating to cell culture media, and is against GlaxoSmithKline. IDEC's lawsuit in this case, seeks a declaration that its manufacture of Zevalin does not infringe GlaxoSmithKline's issued US patents. Corixa Corporation and GlaxoSmithKline have also filed a complaint for patent infringement against IDEC. These actions however, should have no effect on the regulatory process that Zevalin is completing, or prevent IDEC from launching the drug before iodine-131 tositumomab.A year earlier, in March 2001, the Financial Times reported that Bexxar could reach peak sales of $US120 million. In 1998, Coulter Pharmaceutical received a licencee fee payment of $US34 million from SmithKline Beecham (now GSK) in the fourth quarter of the year, as part of the joint development and commercialisation agreement for Bexxar.

    [symbol: see text] Atovaquone + proguanil (Malarone--GlaxoSmithKline) is a fixed-dose combination of two antiparasitic drugs. In 1996, it was licensed in the UK for the treatment of acute, uncomplicated falciparum malaria. Earlier this year, the combination was licensed additionally for prophylaxis of falciparum malaria. The manufacturer claims that, when used for prophylaxis, atovaquone + proguanil "offers 97% efficacy with a side effect profile similar to placebo". Here, we assess these claims and review the place of atovaquone + proguanil as prophylaxis for non-immune people travelling from the UK. PMID:11706518

    The 1990s and early years of this century have seen a series of large-scale mergers and acquisitions in the Pharmaceutical and Biotech arena. These activities each required integration at multiple levels. One of the most important activities is the integration of the R&D pipelines of the participants. We outline the combined portfolio and bioinformatic strategy that was used, and detail the lessons learned for the longer term, from the GlaxoWellcome-SmithKline-Beecham merger in 2000. To date, this has been the largest merger of two equally sized Pharma R&D organisations. PMID:19121408

    Julian Augustus Romaine Smith was one of the surgeons who, in the company of Thomas Dunhill, Hugh Devine, Douglas Shields and David Murray Morton, established Saint Vincent's Hospital, Melbourne, as arguably the premier surgical hospital in Victoria, if not Australia. Smith abandoned a most promising scientific career to study medicine, completing his medical course in Melbourne where he graduated top of his year in 1898/1899. He gained his MD in 1901 and set up practice in Morwell, a Victorian country town, where he initiated his surgical career. In 1905 Smith returned to Melbourne and worked as assistant to Mr F. D. Bird, a prominent surgeon. He travelled overseas in 1906, visiting leading medical centres in England where Almroth Wright's work on vaccination made a deep impression on him. On his return to Australia in 1908 he joined the surgical staff at Saint Vincent's Hospital as surgeon to outpatients, finally retiring as surgeon to inpatients in 1928. Smith was made a Foundation Fellow of the Australasian College of Surgeons in 1927. Smith was regarded by his peers as a brilliant innovative surgeon with a special interest in urology. He became an expert cystoscopist. After he retired, he continued his long-standing interest in portrait photography for which he was considered a master. During World War II he designed and built an elegant roller pump for use in direct blood transfusion. He died in 1947, survived by his wife, a daughter and three sons, one of whom became President of the Royal Australasian College of Surgeons. PMID:11906425

  19. Processing Semblances Induced through Inter-Postsynaptic Functional LINKs, Presumed Biological Parallels of K-Lines Proposed for Building Artificial Intelligence

    The internal sensation of memory, which is available only to the owner of an individual nervous system, is difficult to analyze for its basic elements of operation. We hypothesize that associative learning induces the formation of functional LINK between the postsynapses. During memory retrieval, the activation of either postsynapse re-activates the functional LINK evoking a semblance of sensory activity arriving at its opposite postsynapse, nature of which defines the basic unit of internal sensation – namely, the semblion. In neuronal networks that undergo continuous oscillatory activity at certain levels of their organization re-activation of functional LINKs is expected to induce semblions, enabling the system to continuously learn, self-organize, and demonstrate instantiation, features that can be utilized for developing artificial intelligence (AI). This paper also explains suitability of the inter-postsynaptic functional LINKs to meet the expectations of Minsky’s K-lines, basic elements of a memory theory generated to develop AI and methods to replicate semblances outside the nervous system.

    A new transform coder based on the zonal sampling strategy, which outperforms the JPEG baseline coder with comparable computational complexity, is presented. The primary transform used is the 8- x 8-pixel-block discrete cosine transform, although it can be replaced by other transforms, such as the lapped orthogonal transform, without any change in the algorithm. This coder is originally based on the Chen-Smith coder; therefore we call it an improved Chen-Smith (ICS) coder. However, because many new features were incorporated in this improved version, it largely outperforms its predecessor. Key approaches in the ICS coder, such as a new quantizer design, arithmetic coders, noninteger bit-rate allocation, decimalized variance maps, distance-based block classification, and human visual sensitivity weighting, are essential for its high performance, Image compression programs were developed and applied to several test images. The results show that the ICS performs substantially better than the JPEG coder.

    Brian Sutton-Smith, renowned scholar of play across multiple disciplines, including psychology, died on March 7, 2015, from complications of Alzheimer's disease. He was 90 years old. For over half a century, Brian Sutton-Smith has been the foremost scholar of play, authoring over 50 books and 350 articles. Sutton-Smith's legacy includes not only his numerous influential works but also his profound impact on scholars of play. He advocated an interdisciplinary approach as essential to play research. His noteworthy scholarship established a focus on play as a serious subject of investigation, a focus on real children and their activities over child developmental norms, and a focus on the adaptive variability of play over play's variables. As a psychology professor at Teachers College, Columbia University (1967-1977), Brian entered the most prolific period of his life. Brian's professorship and role as head of the Graduate Program in Human Development at the University of Pennsylvania (1977-1994) confirmed his interdisciplinary approach as he taught and mentored graduate students in psychology, education, and folklore.

    Analysis of more than 36 years of time series of seven parameters measured in the NSO/AFRL/Sac Peak K-line monitoring program elucidates five elucidates five components of the variation: (1) the solar cycle (period approx. 11 years), (2) quasi-periodic variations (periods approx 100 days), (3) a broad band stochastic process (wide range of periods), (4) rotational modulation, and (5) random observational errors. Correlation and power spectrum analyses elucidate periodic and aperiodic variation of the chromospheric parameters. Time-frequency analysis illuminates periodic and quasi periodic signals, details of frequency modulation due to differential rotation, and in particular elucidates the rather complex harmonic structure (1) and (2) at time scales in the range approx 0.1 - 10 years. These results using only full-disk data further suggest that similar analyses will be useful at detecting and characterizing differential rotation in stars from stellar light-curves such as those being produced by NASA's Kepler observatory. Component (3) consists of variations over a range of timescales, in the manner of a 1/f random noise process. A timedependent Wilson-Bappu effect appears to be present in the solar cycle variations (1), but not in the stochastic process (3). Component (4) characterizes differential rotation of the active regions, and (5) is of course not characteristic of solar variability, but the fact that the observational errors are quite small greatly facilitates the analysis of the other components. The recent data suggest that the current cycle is starting late and may be relatively weak.

    Alex has worked at GlaxoSmithKline for the past 15years and currently works within the bioanalytical and toxicokinetic group in the United Kingdom. Alex's role in previous years has been the in-house support of preclinical and clinical bioanalysis, from method development through to sample analysis activities as well as acting as PI for GLP bioanalysis and toxicokinetics. For the past two years, Alex has applied this analytical and regulatory experience to focus on the outsourcing of preclinical bioanalysis, toxicokinetics and clinical bioanalysis, working closely with multiple bioanalytical and in-life CRO partners worldwide. Alex works to support DMPK and Safety Assessment outsourcing activities for GSK across multiple therapeutic areas, from the first GLP study through to late stage clinical PK studies. Transfer and cross-validation of an existing analytical assay between a laboratory providing current analytical support, and a laboratory needed for new or additional support, can present the bioanalyst with numerous challenges. These challenges can be technical or logistical in nature and may prove to be significant when transferring an assay between laboratories in different continents. Part of GlaxoSmithKline's strategy to improve confidence in providing quality data, is to cross-validate between laboratories. If the cross-validation fails predefined acceptance criteria, then a subsequent investigation would follow. This may also prove to be challenging. The importance of thorough planning and good communication throughout assay transfer, cross-validation and any subsequent investigations is illustrated in this case study. PMID:25932517

    We investigated the breeding performance of American black ducks (Anas rubripes) on Smith Island, Chesapeake Bay, to improve our understanding of island black duck breeding ecology and to make management recommendations to enhance productivity. During 1995-96, we implanted 56 female black ducks with 20-g radio transmitters and tracked 35 of the individuals through the breeding season to locate nests, determine nest fate, and identify brood habitat. We also increased preseason banding efforts and compared capture characteristics over 12 years with those from the Deal Island Wildlife Management Area, a banding site on the mainland of Tangier Sound. A low rate of nesting (37%), lack of renesting, and poor hatching success (31%) indicated that island salt marsh habitats present a harsh environment for breeding black ducks. Black ducks located 11 of 13 nests (85%) in black needlerush (Juncus roemerianus) marsh where they were vulnerable to flooding from extreme tides and to egg predators. No nests were found on forested tree hammocks, a feature that distinguishes Smith Island from nearby South Marsh and Bloodsworth Islands. Nest predators included red foxes (Vulpes vulpes), herring gulls (Larus argentams), fish crows (Corvus ossifragus), and, potentially, Norway rats (Rattus norvegicus). Unlike mainland red foxes, foxes radio tracked on Smith Island were found to be capable swimmers and effective low marsh predators. We found shoreline meadows of widgeon grass (Ruppia maritima) to be important foraging sites for black ducks and suspected that the virtual absence of fresh water in this high salinity environment (1217+ ppt) to incur some cost in terms of growth and survival of ducklings. Preseason bandings revealed a high proportion of banded adults and a strong positive correlation in age ratios with the Deal Island banding site. This latter finding strongly suggests a negative universal effect of storm tides on nest success for Tangier Sound black ducks. Management to reduce nest predators, especially gulls and foxes, likely will have the greatest immediate benefit for island breeding black ducks.

    In February 1983, the US Department of Energy (DOE) identified a location in Deaf Smith County, Texas, as one of nine potentially acceptable sites for mined geologic repository for spent nuclear fuel and high-level radioactive waste. To determine their suitability, the Deaf Smith County site and eight other potentially acceptable sites have been evaluated in accordance with the DOE's General Guidelines for the Recommendation of Sites for the Nuclear Waste Repositories. The Deaf Smith County site is in the Permian Basin, which is one of five distinct geohydrologic settings considered for the first repository. On the basis of the evaluations reported in this EA, the DOE has found that the Deaf Smith County site is not disqualified under the guidelines. On the basis of these findings, the DOE is nominating the Deaf Smith County site as one of five sites suitable for characterization. 3 figs.

    We report a child of 3 years 9 months with the Marshall-Smith syndrome (MSS), characterised by the typical facial features, developmental delay, and advanced bone age. After the diagnosis was made at 5 months of age, careful observation for respiratory complications and failure to thrive was initiated. By 3 1/2 years of age, although our patient had no life threatening respiratory complications, investigation showed significant upper airway obstruction, which has been successfully treated. Aggressive treatment for failure to thrive has also allowed her to maintain a weight on the 50th centile. The purpose of this report is to suggest that early diagnosis and aggressive management may improve the ultimate prognosis with respect to the respiratory and feeding difficulties seen in this rare syndrome.

    Smith`s disease (also known as dentatorubral pallidoluysian atrophy or DRPLA) is a rare, progressive, fatal neuropsychiatric disorder similar to Huntington`s disease (HD). Smith`s disease is characterized by ataxia, choreoathetosis, myoclonic epilepsy, dementia, and genetic anticipation. Neuropathological findings include prominent cell loss in the dentate nucleus of the cerebellum, the globus pallidus, the red nucleus, and the subthalamic nucleus. An expansion of a CAG trinucleotide repeat encoding polyglutamine in a gene originally identified in our laboratory as part of a program to clone candidate genes for disorders with anticipation has recently been found to cause this disorder. We have identified two families that demonstrate the pathological and genetic features (expanded CAG repeat and anticipation) of this disease. Northern analysis indicates that the gene, which we have termed atrophin-1, is widely expressed as a 5 kb mRNA in normal human brain and peripheral tissues. Brain expression is highest in the cerebellum. The developmental expression of the rat homologues of IT-15 (the gene in which a CAG expansion causes HD) and atrophin-1 were compared. Atrophin-1 was most highly expressed in early rat embryo brain (E16), whereas the greatest expression of IT-15 was in the adult rat brain. Cloning and sequencing of the open reading frame from inserts contained in brain cDNA libraries is in progress. In addition to the CAG repeat, the ORF contains an unusual region of alternating acidic and basic amino acids. Further characterization of atrophin-1, and comparison of it to other genes in which trinucleotide repeat expansion leads to neuropsychiatric disorders, should lead to a better understanding of the pathophysiology by which CAG repeat expansion causes human disease.

    Smith-Magenis syndrome (SMS) is characterized by distinctive facial and skeletal features, developmental delay, cognitive impairment, and behavioral abnormalities, including self-injurious behaviors. We aimed to investigate whether cutaneous features are common in SMS. We performed a complete skin examination in 20 young SMS patients. Skin features secondary to self-injurious behavior, such as bites, abrasions, dystrophic scars, limited spots of hyperkeratosis, anomalies of the nails, and whitlows, were found in the majority of patients. Acral pachydermia and fissured plantar keratoderma were common. Xerosis was constant and associated with extensive keratosis pilaris in the majority of patients. Dermatofibromas were frequent in older patients. The hair was dense and shiny, with an unusual hairline. Eyelash trichomegaly and heavy brows were common, as well as folliculitis on the back. The skin features of SMS have rarely been reported in the literature. Some of these are the consequence of neurobehavioral features, but some cutaneous features and abnormalities of appendages have not been reported in other related syndromes. Skin manifestations of SMS are varied, sometimes induced by self-injurious behavior and sometimes more specific. It remains to be determined whether the combination of the two kinds of signs could contribute to early diagnosis of the syndrome. PMID:25684097

    Reports an error in "Noradrenergic alpha-2 receptor modulators in the ventral bed nucleus of the stria terminalis: Effects on anxiety behavior in postpartum and virgin female rats" by Carl D. Smith, Christopher C. Piasecki, Marcus Weera, Joshua Olszewicz and Joseph S. Lonstein (Behavioral Neuroscience, 2013[Aug], Vol 127[4], 582-597). Table 2 should have used the ratio of 5HIAA/serotonin - rather than the inverse - as the indicator of serotonin turnover. Using the correct ratio, differences in serotonin turnover between the postpartum and virgin females are: BSTv - 1.11 0.06 vs 0.79 0.11 (t 2.57, p 0.05); BSTd - 1.01 0.07 vs 0.68 0.11 (t 2.58, p 0.05). That is, contrary to what was originally reported, postpartum females had higher serotonin turnover in both subregions of the BST compared to virgins. The penultimate sentence in the abstract noting serotonin turnover in mothers has been corrected in the online version of this article. (The following abstract of the original article appeared in record 2013-22430-001.) Emotional hyperreactivity can inhibit maternal responsiveness in female rats and other animals. Maternal behavior in postpartum rats is disrupted by increasing norepinephrine release in the ventral bed nucleus of the stria terminalis (BSTv) with the α2-autoreceptor antagonist, yohimbine, or the more selective α2-autoreceptor antagonist, idazoxan (Smith et al., 2012). Because high noradrenergic activity in the BSTv can also increase anxiety-related behaviors, increased anxiety may underlie the disrupted mothering of dams given yohimbine or idazoxan. To assess this possibility, anxiety-related behaviors in an elevated plus maze were assessed in postpartum rats after administration of yohimbine or idazoxan. It was further assessed if the α2-autoreceptor agonist clonidine (which decreases norepinephrine release) would, conversely, reduce dams' anxiety. Groups of diestrous virgins were also examined. It was found that peripheral or intra-BSTv yohimbine did increase anxiety-related behavior in postpartum females. However, BSTv infusion of idazoxan did not reproduce yohimbine's anxiogenic effects and anxiety was not reduced by peripheral or intra-BSTv clonidine. Because yohimbine is a weak 5HT1A receptor agonist, other groups of females received BSTv infusion of the 5HT1A receptor agonist 8OH-DPAT, but it did not alter their anxiety-related behavior. Lastly, levels of norepinephrine and serotonin in tissue punches from the BSTv did not differ between postpartum and diestrous rats, but serotonin turnover was higher in mothers. These results suggest that the impaired maternal behavior after BSTv infusion of yohimbine or idazoxan cannot both be readily explained by an increase in dams' anxiety, and that BSTv α2-autoreceptor modulation alone has little influence on anxiety-related behaviors in postpartum or diestrous rats.

    We report the first detection of magnetic fields associated with the Smith High Velocity Cloud. We use a catalog of Faraday rotation measures toward extragalactic radio sources behind the Smith Cloud, new H I observations from the Robert C. Byrd Green Bank Telescope, and a spectroscopic map of Hα from the Wisconsin H-Alpha Mapper Northern Sky Survey. There are enhancements in rotation measure (RM) of ≈100 rad m{sup –2} which are generally well correlated with decelerated Hα emission. We estimate a lower limit on the line-of-sight component of the field of ≈8 μG along a decelerated filament; this is a lower limit due to our assumptions about the geometry. No RM excess is evident in sightlines dominated by H I or Hα at the velocity of the Smith Cloud. The smooth Hα morphology of the emission at the Smith Cloud velocity suggests photoionization by the Galactic ionizing radiation field as the dominant ionization mechanism, while the filamentary morphology and high (≈1 Rayleigh) Hα intensity of the lower-velocity magnetized ionized gas suggests an ionization process associated with shocks due to interaction with the Galactic interstellar medium. The presence of the magnetic field may contribute to the survival of high velocity clouds like the Smith Cloud as they move from the Galactic halo to the disk. We expect these data to provide a test for magnetohydrodynamic simulations of infalling gas.

  15. SR-71 Pilot Rogers E. Smith

    NASA Technical Reports Server (NTRS)

    1992-01-01

    Research pilot Rogers E. Smith is shown here in front of the SR-71 Blackbird he flew for NASA. Rogers was one of the two original NASA research pilots assigned to the SR-71 high speed research program at NASA's Ames-Dryden Flight Research Facility (later, Dryden Flight Research Center, Edwards, California. Smith has been a NASA research pilot at Dryden since 1982. Data from the SR-71 program will be used to aid designers of future supersonic aircraft and propulsion systems. The SR-71 is capable of flying more than 2200 mph (Mach 3+) and at altitudes of over 80,000 feet. Two SR-71 aircraft have been used by NASA as testbeds for high-speed and high-altitude aeronautical research. The aircraft, an SR-71A and an SR-71B pilot trainer aircraft, have been based here at NASA's Dryden Flight Research Center, Edwards, California. They were transferred to NASA after the U.S. Air Force program was cancelled. As research platforms, the aircraft can cruise at Mach 3 for more than one hour. For thermal experiments, this can produce heat soak temperatures of over 600 degrees Fahrenheit (F). This operating environment makes these aircraft excellent platforms to carry out research and experiments in a variety of areas -- aerodynamics, propulsion, structures, thermal protection materials, high-speed and high-temperature instrumentation, atmospheric studies, and sonic boom characterization. The SR-71 was used in a program to study ways of reducing sonic booms or over pressures that are heard on the ground, much like sharp thunderclaps, when an aircraft exceeds the speed of sound. Data from this Sonic Boom Mitigation Study could eventually lead to aircraft designs that would reduce the 'peak' overpressures of sonic booms and minimize the startling affect they produce on the ground. One of the first major experiments to be flown in the NASA SR-71 program was a laser air data collection system. It used laser light instead of air pressure to produce airspeed and attitude reference data, such as angle of attack and sideslip, which are normally obtained with small tubes and vanes extending into the airstream. One of Dryden's SR-71s was used for the Linear Aerospike Rocket Engine, or LASRE Experiment. Another earlier project consisted of a series of flights using the SR-71 as a science camera platform for NASA's Jet Propulsion Laboratory in Pasadena, California. An upward-looking ultraviolet video camera placed in the SR-71's nosebay studied a variety of celestial objects in wavelengths that are blocked to ground-based astronomers. Earlier in its history, Dryden had a decade of past experience at sustained speeds above Mach 3. Two YF-12A aircraft and an SR-71 designated as a YF-12C were flown at the center between December 1969 and November 1979 in a joint NASA/USAF program to learn more about the capabilities and limitations of high-speed, high-altitude flight. The YF-12As were prototypes of a planned interceptor aircraft based on a design that later evolved into the SR-71 reconnaissance aircraft. Dave Lux was the NASA SR-71 project manger for much of the decade of the 1990s, followed by Steve Schmidt. Developed for the USAF as reconnaissance aircraft more than 30 years ago, SR-71s are still the world's fastest and highest-flying production aircraft. The aircraft can fly at speeds of more than 2,200 miles per hour (Mach 3+, or more than three times the speed of sound) and at altitudes of over 85,000 feet. The Lockheed Skunk Works (now Lockheed Martin) built the original SR-71 aircraft. Each aircraft is 107.4 feet long, has a wingspan of 55.6 feet, and is 18.5 feet high (from the ground to the top of the rudders, when parked). Gross takeoff weight is about 140,000 pounds, including a possible fuel weight of 80,280 pounds. The airframes are built almost entirely of titanium and titanium alloys to withstand heat generated by sustained Mach 3 flight. Aerodynamic control surfaces consist of all-moving vertical tail surfaces, ailerons on the outer wings, and elevators on the trailing edges between the engine exhaust nozzles. The two SR-71s at Dryden have been assigned the following NASA tail numbers: NASA 844 (A model), military serial 61-7980 and NASA 831 (B model), military serial 61-7956. From 1990 through 1994, Dryden also had another 'A' model, NASA 832, military serial 61-7971. This aircraft was returned to the USAF inventory and was the first aircraft reactivated for USAF reconnaissance purposes in 1995. It has since returned to Dryden along with SR-71A 61-7967.

    The power radiation pattern of Smith-Purcell radiation is measured at various latitudes and azimuth angles relative to the electron beam. The experimental data are used to evaluate the various models and the physical mechanisms previously suggested to describe Smith-Purcell radiation. Good agreement is observed between the experimental data and the theoretical curves derive from Van den Berg's analysis (J. Opt. Soc. Am. 63, 1588 (1973)). The radiation mechanism proposed by Salisbury (J. Opt. Soc. Am. 60, 1279 (1970)) was analyzed an shown to be too small to account for the measured radiation. The experimantal and Van den Berg's theory predict stronger emission at azimuthal angles off the plane perpendicular to the gratings. This observation leads to conclusions regarding the design of optical cavities for Smith-Purcell free-electron lasers and orotron millimeter-wavelength-radiation tube devices.

    Recent discoveries of star formation in regions previously thought impossible implies new criteria for where stars can form. The Smith Cloud, a high velocity cloud (HVC) primarily comprised of neutral hydrogen located 12 kpc away in the halo of the Milky Way, meets these criteria by having a large reservoir of gas and the tidal pull of the Milky Way as a mechanism for perturbing the gas. We obtained GALEX NUV magnitudes for stars in the field of the Smith Cloud. These sources were matched with WISE and 2MASS catalogs to obtain infrared magnitudes. We determined the expected colors of young stars in these wavelength bands using synthetic spectral libraries. By comparing the observed UV and IR colors of stars to the expected colors of young stars, while also comparing star positions to existing 21cm data, we aim to isolate possible recent star formation in the Smith Cloud.

    Abstract Heteranassa Smith (Erebidae, Omopterini), native to the southwestern United States and Mexico, includes two recognized species, namely Heteranassa mima (Harvey) and Heteranassa fraterna Smith. These are separated mainly by subtle differences in wing color and pattern, leading to speculation about the validity of the described species. This study examines variation in external and internal morphology across the geographic range of the genus, aiming to clarify species limits, describe morphology, and provide a comprehensive assessment of variation within the genus. Results indicate that Heteranassa fraterna syn. n., is a junior synonym of Heteranassa mima. PMID:26692786

    In this paper, a modified Smith predictor control scheme is proposed for periodic disturbance rejection in both stable and unstable processes with time delay. Without affecting the superior setpoint response of Smith predictor control, the regulation performance under periodic disturbance can be enhanced significantly by the proposed design. Meanwhile, the asymptotical rejection for non-periodic disturbance will also be improved. Internal stability is investigated for a closed-loop control system. The effectiveness of the proposed scheme will be demonstrated by simulations as well as a test on an experimental thermal system. PMID:17663989

  6. Gas Currently Accreting Onto the Milky Way: The Smith Cloud

    2015-08-01

    Active gas accretion onto the Milky Way is observed in an object called the Smith Cloud, which contains several million solar masses of neutral and warm ionized gas. It is several kpc in size and is located two kpc below the Galactic plane, on a trajectory that will intersect the Galactic plane in a few tens of million years, fueling future generations of star formation in the inner half of the Milky Way.The Smith Cloud appears to be purely gaseous with no stellar counterpart, but there are suggestions that its existence and survival require that it be embedded in a dark matter halo of a few 10^8 solar masses.The Smith Cloud is interacting with the Milky Way's gaseous halo and losing mass to it; the interaction shows indications of Raleigh-Taylor and Kelvin-Helmholtz instabilities. Portions of the cloud have already been decellerated to near local rest velocity in the halo. It may have a magnetic field.I will present new 21cm HI observations of the Smith Cloud made with the Green Bank Telescope that bear on its origin and fate. New UV spectra from COS/HST will also be presented that give estimates of its abundances and ionization stage.

  7. Modeling Ocean-Forced Changes in Smith Glacier

    2014-12-01

    Glaciers along the Amundsen Coast are changing rapidly, which has drawn substantial scientific and public attention. Modeling and observation suggest warm-water intrusion and consequent melting as the cause of observed changes, and that unstoppable retreat may have already been triggered in some drainages. While Pine Island and Thwaites Glaciers are losing the most mass and have been the predominant objects study, other systems, particularly Smith, Pope and Kohler Glaciers and the corresponding Dotson and Crosson Shelves, are changing more rapidly relative to their size. Though smaller, these glaciers still have potentially large implications for overall regional dynamics as their beds connect below sea level to surrounding basins. In particular, the long, deep trough of Smith Glacier nearly links to the large eastern tributary of Thwaites, potentially causing rapid changes of Smith to have significant impact on the continuing retreat of Thwaites.We implemented a numerical model in Elmer/Ice, an open-source, full-Stokes, finite-element software package, to investigate the response of the Smith/Pope/Kohler system to different initial conditions. We use various parameterizations of sub-shelf melting with constant magnitude to examine the sensitivity of overall dynamics to melt distribution. Because melt distribution affects lateral buttressing and upstream grounded areas, it is potentially an important control on ice shelf and outlet glacier dynamics. Through comparison to the most recent velocity data, we evaluate the ability of differing melt parameterizations to reproduce the behavior currently seen in Smith/Pope/Kohler glaciers. In addition, we investigate the effect of using different years of velocity data with constant elevation input when initiating model runs. By comparing results over the satellite record to initiation with synchronous observations, we assess the accuracy of the often necessary practice of using differently timestamped datasets.

    A large body of compelling preclinical evidence supports the clinical use of neurokinin (NK) receptor antagonists in a plethora of CNS and non-CNS therapeutic areas. The significant investment made in this area over the past 2 decades culminated with the observation that NK(1) receptor antagonists elicited clinical efficacy in major depression disorders. In addition, aprepitant (Merck) was launched as a new drug able to prevent chemotherapy-induced nausea and vomiting (CINV). After the discovery by GlaxoSmithKline of vestipitant, a wide drug discovery program was launched aimed at identifying additional clinical candidates. New compounds were designed to maximize affinity at the NK(1) receptor binding site while retaining suitable physicochemical characteristics to ensure excellent pharmacokinetic and pharmacodynamic properties in vivo. Herein we describe the discovery process of a new NK(1) receptor antagonist (casopitant) selected as clinical candidate and progressed into clinical studies to treat major depression disorders.

  16. HTS and hit finding in academia – from chemical genomics to drug discovery

    PubMed Central

    Frearson, Julie A.; Collie, Iain T.

    2009-01-01

    The liaison between academia and the pharmaceutical industry was originally served primarily through the scientific literature and limited, specific industry–academia partnerships. Some of these partnerships have resulted in drugs on the market, such as Vorinostat (Memorial Sloan-Kettering Cancer Centre and Merck) and Tenofovir (University of Leuven; Institute of Organic Chemistry and Biochemistry, Czech Republic; and GlaxoSmithKline), but the timescales from concept to clinic have, in most cases, taken many decades. We now find ourselves in a world in which the edges between these sectors are more blurred and the establishment and acceptance of high-throughput screening alongside the wider concept of ‘hit discovery’ in academia provides one of the key platforms required to enable this sector to contribute directly to addressing unmet medical need.

  17. [Transparency in biomedical research: about the risks associated with the use of Avandia].

    2010-09-01

    The question of how and when to communicate potential risks associated with new drugs has remained an important focus of tension between the pharmaceutical industry and regulatory entities, such as the American Food and Drug Administration. Recently there has been widespread concern related to the cardiovascular risks associated with the use of Avandia, a rosiglitazone produced by Glaxo Smith Kline. In fact, several metaanalyses involving rosiglitazone provided a relatively consistent message that rosiglitazone increases the risk of myocardial ischemic events. In the present article, we review the controversy regarding the way the pharmaceutical company handled this issue, and we describe examples of inappropriate conduct regarding an industry-sponsored clinical trial with this drug. We raise several important ethical questions related to the way researchers handle conflicts of interest when they are employees of the pharmaceutical industry. Finally, we discuss the requirements to conduct biomedical research funded by the pharmaceutical industry in Chile.

    Handler, Nancy S; Handler, Marc Z; Majewski, Slawomir; Schwartz, Robert A

    2015-11-01

    As of December 2014, there were 3 approved vaccines for human papillomavirus (HPV): bivalent Cervarix (GlaxoSmithKline, New York, NY), quadrivalent Gardasil (Merck and Co, Kenilworth, NJ), and 9-valent Gardasil-9 (Merck and Co). The average cost per dose is $120, with a recommended 3-dose course. The quadrivalent vaccine is the most widely administered worldwide. As with the bivalent and 9-valent vaccines, the vaccine is considered safe, although concerns have been raised. In addition to immunization against the targeted HPV types, there is evidence that there is cross protection against other types of HPV. This continuing medical education review evaluates the differences in vaccines that are currently on the market; part II focuses on the cost-effectiveness of vaccination, the HPV vaccination programs currently instituted around the globe, efficacy, and safety.

    Pertussis is an acute respiratory infection characterized by paroxysmal cough and inspiratory whoop for over 2 weeks. The incidence of pertussis has decreased markedly after the introduction of DTwP/DTaP vaccine, but the incidence of pertussis has increased steadily among young infant and among adolescents and adults in many countries. Td vaccine was used in this age group but the increase in pertussis has lead to the development of a Tdap vaccine. The Tdap vaccine is a Td vaccine with a pertussis vaccine added and is thought to decrease the incidence and transmission of pertussis in the respective age group. In Korea, two products are approved by the KOREA FOOD & DRUG ADMINISTRATION, which are ADACEL™ (Sanofi-Pasteur, Totonto, Ontario, Canada) and BOOSTRIX® (GlaxoSmithKline Biologicals, Rixensart, Belgium) for those aged between 11-64. This report summarizes the recommendations approved by the Committee on Infectious Diseases, the Korean Pediatric Society. PMID:21738546

    National Electrostatics Corporation (NEC), Massachusetts Institute of Technology (MIT), and GlaxoSmithKline (GSK) collectively have been developing an interface to introduce CO2 produced by the laser combustion of liquid chromatograph eluate deposited on a CuO substrate directly into the ion source of an AMS system, thereby bypassing the customary graphitization process. The Automated Laser Gas Interface (ALGI) converts dried liquid samples to CO2 gas quickly and efficiently, allowing 96 samples to be measured in as little as 16 h. 14C:12C ratios stabilize typically within 2 min of analysis time per sample. Presented is the recent progress of NECs ALGI, a stand-alone accessory to an NEC gas-enabled multi-cathode source of negative ions by Cs sputtering (MC-SNICS) ion source.

  3. Extracting SAR Information from a Large Collection of Anti-Malarial Screening Hits by NSG-SPT Analysis

    PubMed Central

    2011-01-01

    We combine two graphical SAR analysis methods, Network-like Similarity Graphs (NSGs) and Similarity-Potency Trees (SPTs), to search for SAR information in a large and heterogeneous compound data set containing more than 13,000 antimalarial screening hits that was recently released by GlaxoSmithKline (GSK). The NSG-SPT approach first identifies subsets of compounds inducing local SAR discontinuity in data sets and then extracts available SAR information from these subsets in a graphically intuitive manner. Applying the NSG-SPT analysis scheme, we have identified in the GSK collection compound subsets of high local SAR information content including both known and previously unknown antimalarial chemotypes, which yielded interpretable SAR patterns. This information should be helpful to prioritize and select antimalarial candidate compounds for further chemical exploration. Furthermore, the NSG-SPT tools are publicly available, and our study also shows how to practically apply these SAR analysis methods to study large compound data sets. PMID:24900303

  4. SMITH: a LIMS for handling next-generation sequencing workflows

    PubMed Central

    2014-01-01

    Background Life-science laboratories make increasing use of Next Generation Sequencing (NGS) for studying bio-macromolecules and their interactions. Array-based methods for measuring gene expression or protein-DNA interactions are being replaced by RNA-Seq and ChIP-Seq. Sequencing is generally performed by specialized facilities that have to keep track of sequencing requests, trace samples, ensure quality and make data available according to predefined privileges. An integrated tool helps to troubleshoot problems, to maintain a high quality standard, to reduce time and costs. Commercial and non-commercial tools called LIMS (Laboratory Information Management Systems) are available for this purpose. However, they often come at prohibitive cost and/or lack the flexibility and scalability needed to adjust seamlessly to the frequently changing protocols employed. In order to manage the flow of sequencing data produced at the Genomic Unit of the Italian Institute of Technology (IIT), we developed SMITH (Sequencing Machine Information Tracking and Handling). Methods SMITH is a web application with a MySQL server at the backend. Wet-lab scientists of the Centre for Genomic Science and database experts from the Politecnico of Milan in the context of a Genomic Data Model Project developed SMITH. The data base schema stores all the information of an NGS experiment, including the descriptions of all protocols and algorithms used in the process. Notably, an attribute-value table allows associating an unconstrained textual description to each sample and all the data produced afterwards. This method permits the creation of metadata that can be used to search the database for specific files as well as for statistical analyses. Results SMITH runs automatically and limits direct human interaction mainly to administrative tasks. SMITH data-delivery procedures were standardized making it easier for biologists and analysts to navigate the data. Automation also helps saving time. The workflows are available through an API provided by the workflow management system. The parameters and input data are passed to the workflow engine that performs de-multiplexing, quality control, alignments, etc. Conclusions SMITH standardizes, automates, and speeds up sequencing workflows. Annotation of data with key-value pairs facilitates meta-analysis. PMID:25471934

    We determined lung bioavailability of a fluticasone propionate (FP) pressurised metred-dose inhaler (Flovent® HFA; GlaxoSmithKline, Research Triangle Park, NC, USA) administered via AeroChamber Plus® (Monaghan Medical, Plattsburgh, NY, USA) with Facemask and Babyhaler® (GlaxoSmithKline) valved holding chambers (VHCs) using a population pharmacokinetic approach. Children from 1 to <4 yrs of age with stable asthma but a clinical need for inhaled corticosteroid therapy were administered 88 µg FP hydrofluoroalkane (2 × 44 µg) twice daily delivered through the two devices in an open-label, randomised crossover manner for 8 days each. Patients were randomised to one of three sparse sampling schedules for blood collection throughout the 12-h dosing interval on the 8th day of each treatment for pharmacokinetic analysis. The area under the FP plasma concentration–time curve (AUC) was determined for each regimen. 17 children completed the study. The population mean AUC following FP with AeroChamber Plus® with Facemask was 97.45 pg·h·mL−1 (95% CI 85.49–113.32 pg·h·mL−1) and with Babyhaler® was 51.55 pg·h·mL−1 (95% CI 34.45–64.46 pg·h·mL−1). The relative bioavailability (Babyhaler®/AeroChamber Plus®) was 0.53 (95% CI 0.30–0.75). Clinically significant differences in lung bioavailability were observed between the devices. VHCs are not interchangeable, as differences in drug delivery to the lung may occur. A population pharmacokinetic approach can be used to determine lung bioavailability of FP. PMID:21933835

    The combined diphtheria-tetanus-acellular pertussis-hepatitis B-poliomyelitis/Haemophilus influenza vaccine (DTPa-HBV-IPV/Hib: Infanrix™ hexa, GlaxoSmithKline Vaccines) is used for primary vaccination of infants in a range of schedules world-wide. Antibody persistence after 4 DTPa-HBV-IPV/Hib doses in the first 2 y of life has been documented, but long-term persistence data following the 3, 5, 11-12 months (3-5-11) infant vaccination schedule, employed for example in Nordic countries, are limited. We assessed antibody persistence in 57 5-year-old children who had received either DTPa-HBV-IPV/Hib or DTPa-IPV/Hib (Infanrix™-IPV/Hib, GlaxoSmithKline Vaccines) in the 3-5-11 schedule. Among DTPa-HBV-IPV/Hib recipients, 7/12 retained seroprotective antibody concentrations for diphtheria, 10/12 for tetanus, 5/12 for hepatitis and 10/12 for Hib. Detectable antibodies were observed for 0/12 children for pertussis toxin (PT), 12/12 for filamentous haemagglutinin (FHA) and 8/12 for pertactin (PRN). Among DTPa-IPV/Hib recipients, 28/45 retained seroprotective anti-diphtheria concentrations, 34/44 for tetanus and 40/45 for Hib. Detectable antibodies were observed for 9/45 children for PT, 41/45 for FHA and 34/45 for PRN. Antibody persistence in DTPa-HBV-IPV/Hib and DTPa-IPV/Hib-vaccinees appeared similar in 5 y olds to that previously observed in children of a similar age who had received 4 prior doses of DTPa-HBV-IPV/Hib (or DTPa-IPV/Hib). As in subjects primed with 4 prior doses, we observed that antibodies markedly declined by 5 y of age, calling for the administration of a pre-school booster dose in order to ensure continued protection against pertussis.

    An injectable Vi-capsular polysaccharide vaccine against typhoid fever is available but vaccine-induced immunity tends to wane over time. The phenomenon of immunotolerance or hyporesponsiveness has earlier been described for polysaccharide vaccines such as pneumococcal capsular polysaccharide vaccine and some publications also suggest a possible immunotolerance after revaccination with Vi-capsular polysaccharide vaccines. In this study, post-immunisation antibody concentrations in adult travellers first vaccinated with a Salmonella typhi Vi-capsular polysaccharide vaccine (primary vaccination group) were compared with those having received one or more vaccinations previously (multiple vaccinations group). Vaccines administered were Typherix(®) (GlaxoSmithKline), Typhim Vi(®) (Sanofi Pasteur MSD) or Hepatyrix(®) (GlaxoSmithKline). Blood samples were obtained prior to vaccination (day 0) and on day 28 (-1/+14) after vaccination. Serum Vi-Antigen IgG concentrations were measured by ELISA. Of the 85 subjects included in the per protocol data set, 45 (53%) belonged to the multiple vaccinations group. In both groups, geometric mean antibody concentrations (GMCs) were significantly higher after vaccination than before vaccination. Pre-vaccination GMCs were lower in the primary vaccination group than in the multiple vaccinations group (3.40 μg/ml versus 6.13 μg/ml, P=0.005), while there was no significant difference in the post vaccination GMCs between groups (11.34 μg/ml versus 14.58 μg/ml, P=0.4). In the multiple vaccinations group, vaccination was performed 18 to 57 months after the last vaccination (median 38 months) and there was a negative correlation between time since last vaccination and antibody concentration on day 0. In conclusion, we were not able to demonstrate a relevant immunotolerance after multiple versus primary vaccination with S. typhi Vi-capsular polysaccharide vaccines. PMID:26144902

  8. Malaria chemoprophylaxis: when should we use it and what are the options?

    PubMed

    Petersen, Eskild

    2004-02-01

    Malaria chemoprophylaxis concerns prescribing healthy individuals medication for an infection they have an unknown chance of getting. Sensible use of malaria chemoprophylaxis is a balance between the risk of infection and death, and the risk of side effects. The risk of infection can be broken down into the risk of being bitten by a malaria-infected mosquito and the risk of the malaria parasites being resistant to the drug used for prophylaxis. Our knowledge of these parameters is patchy. The risk of infection is not uniform at a given location and the standard of living will greatly influence risk. It is suggested that chemoprophylaxis should not be recommended in areas with less than ten reported cases of P. falciparum malaria per 1000 inhabitants per year. The resistance pattern is known to a certain extent but, for instance, diverging opinion of how much resistance to chloroquine there is in West Africa illustrates the lack of data. There is much debate on rare adverse events, which usually escape Phase III studies prior to registration and are only picked up by passive, postmarketing surveillance. The lessons over the past 20 years with the introduction of amodiaquine, pyrimethamine/dapsone (Maloprim, GlaxoSmithKline) and pyrimethamine/sulfadoxine (Fansidar, Roche), which were all withdrawn for prophylaxis after a few years, show how sensitive drugs for chemoprophylaxis are to side effects. Three levels of chemoprophylaxis are used: chloroquine in areas with sensitive P. falciparum, chloroquine plus proguanil in areas with low level chloroquine resistance, and atovaquone/proguanil (Malarone, GlaxoSmithKline), doxycycline or mefloquine (Lariam, Roche) in areas with extensive resistance against chloroquine and proguanil. Primaquine and the primaquone analog tafenoquine may be future alternatives but otherwise there are few new drugs for chemoprophylaxis on the horizon. PMID:15482177

    OBJECTIVEDespite experimental data suggesting a protective effect of peroxisome proliferatoractivated receptor-? agonists with respect to malignancies, results of available epidemiological studies on the incidence of cancer in rosiglitazone-treated patients are not univocal. The aim of this meta-analysis of randomized clinical trials is to assess the effect of rosiglitazone on the incidence of cancer. RESEARCH DESIGN AND METHODSRandomized clinical trials of rosiglitazone with duration of >24 weeks were retrieved through Medline and from the GlaxoSmithKline Web site, which reports main results of all trials sponsored by GlaxoSmithKline; incident malignancies were retrieved from the summary of serious adverse events. Proportions of outcome measures across treatment groups were compared by odds ratios (ORs) and 95% CI. Considering differences in the duration of follow-up among treatment arms in some of the trials, we also calculated the incidence of cancer in rosiglitazone and control groups. RESULTSEighty trials, enrolling 16,332 and 12,522 patients in the rosiglitazone and comparator groups, respectively, were retrieved. Rosiglitazone was not associated with a significant modification of the risk of cancer (OR 0.91 [95% CI 0.711.16], P = 0.44). The incidence of malignancies was significantly lower in rosiglitazone-treated patients than in control groups (0.23 [0.190.26] vs. 0.44 [0.340.58] cases/100 patient-years; P < 0.05). CONCLUSIONSThe use of rosiglitazone appears to be safe in terms of incidence of cancer, whereas its possible protective effect needs to be further investigated. PMID:18375416

  10. Immune memory to hepatitis B persists in children aged 7-8 years, who were vaccinated in infancy with 4 doses of hexavalent DTPa-HBV-IPV/Hib (Infanrix hexa) vaccine.

    Protection against hepatitis B disease relies on either protective serum antibodies or on the ability of the immune system to mount an anamnestic response when confronted with the hepatitis B virus (HBV). This open multicenter study (EUDRACT: 2010-022538-10) measured antibodies to HBV surface antigen (anti-HBs) in 7-8-year-old children who had received 4 doses of hexavalent diphtheria-tetanus-acellular pertussis-HBV-inactivated poliovirus-Hemophilus influenzae type b conjugate vaccine (DTPa-HBV-IPV/Hib: Infanrix hexa; GlaxoSmithKline Vaccines) in the first 2 years of life through routine vaccine services in Germany. The ability of these children to mount an anamnestic response to a challenge dose of monovalent HBV vaccine (Engerix B Kinder; GlaxoSmithKline Vaccines) was also assessed. Before the challenge dose, 78.5% of children had anti-HBs levels ?6.2 mIU/mL (seropositive) and 72.2% had anti-HBs levels ?10 mIU/mL (seroprotected). Post-challenge, 98.9% had anti-HBs levels ?10 mIU/mL and 95.8% had anti-HBs ?100 mIU/mL. An anamnestic response to the challenge was observed in 96.6% of all subjects. The challenge dose was well tolerated, with a reactogenicity and safety profile consistent with published data. DTPa-HBV-IPV/Hib induces long-lasting immune memory to HBV that appears very similar to that induced by monovalent HBV vaccines. Protection against hepatitis B may be conferred through immune memory in subjects who responded to primary vaccination, even when they subsequently lose detectable levels of circulating anti-HBs antibodies.

    Combination vaccines have been shown to improve the timeliness of vaccination and vaccine coverage. Safety and reactogenicity of combined diphtheria-tetanus-acellular pertussis-inactivated poliovirus and Haemophilus influenzae type b vaccine (DTPa-IPV/Hib, Infanrix IPV+Hib, GlaxoSmithKline Biologicals) was assessed in two clinical studies. In Study A, 2,590 subjects received DTPa-IPV/Hib at 3, 4 and 5 months of age with a booster at 18 months. In Study B, 702 subjects received the same schedule but with DTPa-hepatitis B-IPV/Hib (DTPa-HBV-IPV/Hib, Infanrix hexa, GlaxoSmithKline Biologicals) vaccine administered at 5 months of age. Reactogenicity was assessed for four days after each dose using diary cards. Serious adverse events (SAEs) were assessed until 24 months of age. The vaccines were well tolerated. After primary vaccination, irritability was the most frequently reported grade 3 general symptom (0.8% of doses in both studies). Fever (axillary) > 39 degrees C was infrequent (0.3% of doses in Study A; 0.5% of doses in Study B). After the booster dose, the most frequently reported grade 3 symptom was redness (5%) in Study A and pain (0.5%) in Study B. An axillary temperature > 39 degrees C was reported in 1.1% of subjects. Throughout the study period, 646 SAEs were reported, of which 6 SAEs were considered to be vaccination-related. The reactogenicity and safety profile of the combined DTPa-IPV/Hib vaccine was good when used for primary and booster vaccinations in over 3,000 Singaporean infants. Substitution of DTPa-IPV/Hib with DTPa-HBV-IPV/Hib at Month 5 reduced the number of injections required at this age by one. PMID:21323176

    2014-10-01

    In this paper we follow the development and transmission of moral learning from Adam Smith's impartial spectator to Sigmund Freud's superego and then to contemporary psychoanalysis. We argue that defenses are an integral component in the acquisition of any moral system. Elaborating on this argument, we assert that there is a progression from defensive systems that are "closed" to defensive systems that are "open," as defined in a recent work by Novick and Novick. The former system is "static, avoids reality, and is characterized by power dynamics, sadomasochism, and omnipotent defense." The latter, on the other hand, is a system that allows for "joy, creativity, spontaneity, love and it is attuned to reality." Furthermore, while Smith and Freud's systems are more one-person systems of defense, contemporary psychoanalysis has moved to more of a two-person system. PMID:25247288

    It is shown that the distribution function assumed by Mott-Smith determines a unique relation between heat flux, stress, and fluid velocity given by q = (3/2)??u, i.e., it provides a constitutive relation for heat flux, and it also determines a simple expression for this ratio of third-order central moments Q = . These expressions allow the equation of transfer for c x2 to be cast in a form that yields a nonlinear constitutive relation for stress. The results obtained from the Mott-Smith ansatz are compared with the theory of Baganoff and Nathenson and results from a numerical solution of the Boltzmann equation for shock-wave structure obtained by Hicks and Yen.

    We study the dependence of start current in Smith-Purcell backwardwave oscillator (SP-BWO) on grating parameters and electron beam parameters. The attenuation due to finite conductivity of the grating material is taken into account and three-dimensional effects are included in an approximate way in the analysis. We find that the start current can be significantly reduced by optimizing the grating parameters.

    The Statistical mechanician in the street (our Th. Smiths) must be surprised upon hearing popular versions of some of today's most discussed paradoxes in astronomy and cosmology. In fact, rather standard reminders of the meaning of thermal probabilities in statistical mechanics appear to answer the horizon problem (one of the major motivations for inflation theory) and the information paradox (related to black hole physics), at least as they are usually presented. Still the paradoxes point to interesting gaps in our statistical understanding of (quantum) gravitational effects.

    Smith-Lemli-Opitz syndrome is an autosomal recessive mental retardation and multiple malformation syndrome caused by deficiency of the 7-dehydrocholesterol reductase, the enzyme catalyzing the last step in cholesterol biosynthesis. The authors summarize the pathophysiology, epidemiology, clinical picture, diagnostics and therapy of the disease based on a review of the international literature. Since 2004, fourteen patients have been diagnosed with Smith-Lemli-Opitz syndrome in Hungary, which suggests an underdiagnosis of the disease based upon estimated incidence data. Due to deficiency of the 7-dehydrocholesterol reductase, serum cholesterol concentration is low and 7-dehydrocholesterol concentration is elevated in blood and tissues; the latter being highly specific for the syndrome. Detection of disease-causing mutations makes the prenatal diagnosis possible. The clinical spectrum is wide, the most common symptom is syndactyly of the second and third toes. Standard therapy is cholesterol supplementation. Recent publications suggest that oxidative compounds of 7-dehydrocholesterol may play a role in the pathophysiology of the disease as well.

  5. The futility of utility: how market dynamics marginalize Adam Smith

    2000-10-01

    Economic theorizing is based on the postulated, nonempiric notion of utility. Economists assume that prices, dynamics, and market equilibria are supposed to be derived from utility. The results are supposed to represent mathematically the stabilizing action of Adam Smith's invisible hand. In deterministic excess demand dynamics I show the following. A utility function generally does not exist mathematically due to nonintegrable dynamics when production/investment are accounted for, resolving Mirowski's thesis. Price as a function of demand does not exist mathematically either. All equilibria are unstable. I then explain how deterministic chaos can be distinguished from random noise at short times. In the generalization to liquid markets and finance theory described by stochastic excess demand dynamics, I also show the following. Market price distributions cannot be rescaled to describe price movements as ‘equilibrium’ fluctuations about a systematic drift in price. Utility maximization does not describe equilibrium. Maximization of the Gibbs entropy of the observed price distribution of an asset would describe equilibrium, if equilibrium could be achieved, but equilibrium does not describe real, liquid markets (stocks, bonds, foreign exchange). There are three inconsistent definitions of equilibrium used in economics and finance, only one of which is correct. Prices in unregulated free markets are unstable against both noise and rising or falling expectations: Adam Smith's stabilizing invisible hand does not exist, either in mathematical models of liquid market data, or in real market data.

  7. Obituary: Harding Eugene (Gene) Smith, Jr., 1947-2007

    NASA Astrophysics Data System (ADS)

    Lonsdale, Carol; Soifer, Tom

    2009-01-01

    Harding Eugene Smith Junior, or Gene, as he was known to family, friends, and colleagues, passed away after an automobile accident in Encinitas, California, on 16 August 2007. He was 60 years old. Gene had recently retired from UCSD after thirty years of service. A memorial service was held at Quail Botanical Gardens in Encinitas, California, on 23 August 2007. A web page is dedicated to his memory at http://harding.smith.muchloved.com, where contributions of memories are invited. Gene was born in San Jose, California in 1947, to Harding Eugene Smith Senior, and Bernice Smith (nee Smith). Harding Smith Senior was an air-force navigator; therefore Gene spent his childhood moving from one air-force base to another. Although an only child, Gene was very close to his cousin Meg, whom he lived nearby to in Gilroy for a time, and the two were like brother and sister. The elder Harding Smith was lost in action over Cambodia in the mid-sixties. Gene was a dedicated student, a boy scout, and a Presidential Scholar. He majored in Physics at Caltech, where he also took a lively interest in the football team and the Glee Club, and was elected a House Officer. To his close friends, he was known at Caltech as Smitty, and the closest of them was Rob Drew, who gave a glimpse into that period of Gene's life at the memorial: "Gene arrived early at campus his first year, in response to an invitation to join the football team. Gene's size and features reminded the head coach of a long-forgotten player named 'Johnson.' After a few days of confusion, Gene simply replaced the name on his helmet. 'Johnson!' coach would yell, 'get in there!' If Johnson was going to get to play, Gene was going to be the best Johnson available!" Gene spent the summer of 1966 working at Kitt Peak, where his lifetime love of observing with ground-based telescopes began, though he learned some things the hard way, such as the fact that trying to squeeze 40,000 numbers onto a computer that stored only 32,000 resulted in blown fuses. In a final letter of that summer back to Drew he wrote: "My summer is now complete. I have achieved the highest pinnacle in my quest for fulfillment. Striking a blow for humanity I just blew the whole Kitt Peak CDC3200 computer system. Those fuses were nothing compared to this!" Gene's graduate work, on the metal abundances in HII regions of nearby galaxies, was done at Berkeley, where Hyron Spinrad was his thesis advisor. He loved observing and spent numerous fun nights at Lick, Kitt Peak, Cerro Tololo, Keck, and many other observatories. He joined Margaret Burbidge at UCSD for a postdoctoral fellowship, and joined the teaching faculty there in 1978. Gene spent his entire professional career at UCSD. His research ranged from the study of quasar absorptions lines to the astrophysics of Ultra-luminous Infrared Galaxies. He was a key participant in UC-wide astronomy support, including being the chair of the science-advisory committee for the Ten Meter Telescope project, which later "morphed" into the Keck Observatory. His contributions to enabling that project were both essential and unheralded. Gene was a dedicated and enthusiastic teacher. One of his favorite undergraduate classes gave him the opportunity to dress up in Renaissance garb and pretend to be Galileo, while the experiment most loved by his students was when they got to attempt to drop an egg on his head from several stories high. Gene was also an outstanding advisor and mentor, and both his first post-doc, Rick Puetter, and his last graduate student, Brian Siana, were able to attend his memorial service and provide some special memories of their experiences with him. Rick recalled a memorable trip to Cerro Tololo when they packed up two infrared spectrometers for the trip, and everything conceivable went wrong, from inspections at the airport to spectrometer parts broken on the plane and instrument failures at the observatory, to finally being completely clouded out. Brian recounted: "I spent countless cloudy nights listening to Gene's stories that began with "When men were men and giants roamed the Earth . . . ". I still don't know what that means, but it always preceded some sage advice." Besides astrophysics, Gene's passions included horse riding (the faster the better), sailing, hiking, the northern California coast and mountains, black-and-white photography, extremely strong coffee, travel (especially European castles and cathedrals, and any road-less-traveled that he came across), cooking and fine restaurants, Native American pottery, basketware and kachinas, and classical music. He also loved to sing, and friends would say he had a song for every occasion. He was a dedicated and enthusiastic supporter of all causes environmental and conservationist, and among figures he greatly admired were John Muir and Ansel Adams. Gene is survived by his wife of eighteen years, Dr. Carol Jean Lonsdale; step-daughter Kimberley; daughter Tamsyn; cousins Meg and Chris Bailey; in-laws Colin and Marilou Lonsdale, and Graham Lonsdale; niece Joanna; and two nephews Greg and Wes. He is also greatly missed by his many friends and colleagues, his golden retriever, Jasper, and his palomino horse, Sundance.

    Wilde, Lucy; Silva, Daniel; Oliver, Chris

    2013-12-01

    This natural observation study was designed to evaluate hypothesized elevated 'attention-seeking' and preference for adult attention in Smith-Magenis syndrome. Ten children with Smith-Magenis syndrome were observed across one school day, together with an age matched sample of 10 children with Down syndrome. Levels of attention given to, and vigilance for, adults and peers were recorded and compared. Sequences of behaviour were analyzed to evaluate the temporal relationships between giving and receiving attention during adult-child interactions. Compared to children with Down syndrome, children with Smith-Magenis syndrome gave preferential attention to adults and looked towards adults significantly more than they looked towards peers. Sequential analyses revealed that while children with Smith-Magenis syndrome did not initiate interactions with adults more than children with Down syndrome did, reciprocity between child and adult social behaviours in Smith-Magenis syndrome within interactions was compromised. This less synchronous sequence of child and adult interactions in Smith-Magenis syndrome may be the result of children with Smith-Magenis syndrome attempting to initiate interaction at times when it is unavailable. The marked preference for interacting with adults over peers in Smith-Magenis syndrome indicates atypicality of social interaction in this syndrome. PMID:24120292

  11. SSW Library: An SIMD Smith-Waterman C/C++ Library for Use in Genomic Applications

    PubMed Central

    Zhao, Mengyao; Lee, Wan-Ping; Garrison, Erik P.; Marth, Gabor T.

    2013-01-01

    Background The Smith-Waterman algorithm, which produces the optimal pairwise alignment between two sequences, is frequently used as a key component of fast heuristic read mapping and variation detection tools for next-generation sequencing data. Though various fast Smith-Waterman implementations are developed, they are either designed as monolithic protein database searching tools, which do not return detailed alignment, or are embedded into other tools. These issues make reusing these efficient Smith-Waterman implementations impractical. Results To facilitate easy integration of the fast Single-Instruction-Multiple-Data Smith-Waterman algorithm into third-party software, we wrote a C/C++ library, which extends Farrar’s Striped Smith-Waterman (SSW) to return alignment information in addition to the optimal Smith-Waterman score. In this library we developed a new method to generate the full optimal alignment results and a suboptimal score in linear space at little cost of efficiency. This improvement makes the fast Single-Instruction-Multiple-Data Smith-Waterman become really useful in genomic applications. SSW is available both as a C/C++ software library, as well as a stand-alone alignment tool at: https://github.com/mengyao/Complete-Striped-Smith-Waterman-Library. Conclusions The SSW library has been used in the primary read mapping tool MOSAIK, the split-read mapping program SCISSORS, the MEI detector TANGRAM, and the read-overlap graph generation program RZMBLR. The speeds of the mentioned software are improved significantly by replacing their ordinary Smith-Waterman or banded Smith-Waterman module with the SSW Library. PMID:24324759

    Smith-Lemli-Opitz syndrome (SLOS) is a rare multiple congenital anomaly neurodevelopmental syndrome of impaired cholesterol synthesis. Growth restriction and developmental delay are very common clinical manifestations of SLOS. The degree, etiology, and consequences of growth restriction in SLOS remain an area of limited knowledge to the scientific community. There have been no studies describing the growth parameters and providing reference growth charts for individuals with SLOS. Our longitudinal data from 78 patients between the ages of 0.1 and 16 years with SLOS shows a growth restriction of about 2 standard deviations below the Centers for Disease Control (CDC) norms for age. This study represents comprehensive anthropometric data from the largest cohort available, and proposes growth charts for widespread use in the management and study of individuals with SLOS.

  13. Primate polemic: commentary on Smith, Couchman, and Beran (2014).

    PubMed

    Le Pelley, Mike E

    2014-05-01

    Smith, Couchman, and Beran (2014, pp. 115-131) take issue with recent attempts to account for so-called metacognitive behavior in nonhuman animals in terms of simple processes of associative reinforcement learning. Their arguments rely on appeals to unconvincing and equivocal empirical evidence, and a misrepresentation of the nature of associative learning. Although the existing data do not rule out the possibility that animals possess "true" metacognitive abilities, neither do they currently mandate this conclusion. The suggestion that simple mechanisms might give rise to complex behaviors ties in with recent attempts in cognitive and social psychology, and behavioral neuroscience, to explain human behavior in terms of similar, simple mechanisms. As such this perspective should be seen as an opportunity for comparative psychology, not a threat. PMID:24866001

  14. ULTRA-SHARP solution of the Smith-Hutton problem

    NASA Technical Reports Server (NTRS)

    Leonard, B. P.; Mokhtari, Simin

    1992-01-01

    Highly convective scalar transport involving near-discontinuities and strong streamline curvature was addressed in a paper by Smith and Hutton in 1982, comparing several different convection schemes applied to a specially devised test problem. First order methods showed significant artificial diffusion, whereas higher order methods gave less smearing but had a tendency to overshoot and oscillate. Perhaps because unphysical oscillations are more obvious than unphysical smearing, the intervening period has seen a rise in popularity of low order artificially diffusive schemes, especially in the numerical heat transfer industry. The present paper describes an alternate strategy of using non-artificially diffusive high order methods, while maintaining strictly monotonic transitions through the use of simple flux limited constraints. Limited third order upwinding is usually found to be the most cost effective basic convection scheme. Tighter resolution of discontinuities can be obtained at little additional cost by using automatic adaptive stencil expansion to higher order in local regions, as needed.

    Smith-Magenis syndrome (SMS) is caused by an interstitial microdeletion of chromosome 17p11.2. A few patients with the typical SMS phenotype have RAI1 gene mutations. The syndrome is characterized by minor craniofacial anomalies, short stature, sleep disturbances, behavioural and neurocognitive abnormalities, as well as variable multisystemic manifestations. Periventricular nodular heterotopia (PNH) is a genetically heterogeneous neuronal migration disorder characterized by subependymal heterotopic nodules, and is variably associated with other brain malformations, epileptic seizures and intellectual disability. Here we report on two patients harboring deletions of the 17p11.2 region in whom the SMS typical phenotype was associated with bilateral PNH. Our observations expand the spectrum of chromosomal rearrangements associated with PNH and indicate that abnormal neuronal migration may contribute to the neurocognitive phenotype of SMS.

    Air quality impacts due to site characterization, and repository construction and operation activities were evaluated in the Deaf Smith County Site, Texas environmental assessment (EA). The analyses on which the impact assessments are based made with dispersion models recommended by the EPA for such applications, meteorological data from a nearby representative National Weather Service station at Amarillo, Texas, and available background air quality data from an urban monitoring location. Maximum offsite concentrations of total suspended particulates, nitrogen dioxide, sulfur dioxide, and carbon monoxide were estimated for periods of maximum emissions identified for each pollutant. Estimates of total annual salt deposition resulting from repository salt handling operations were also made. 36 refs., 5 figs., 17 tabs.

  19. The analysis of convolutional codes via the extended Smith algorithm

    NASA Technical Reports Server (NTRS)

    Mceliece, R. J.; Onyszchuk, I.

    1993-01-01

    Convolutional codes have been the central part of most error-control systems in deep-space communication for many years. Almost all such applications, however, have used the restricted class of (n,1), also known as 'rate 1/n,' convolutional codes. The more general class of (n,k) convolutional codes contains many potentially useful codes, but their algebraic theory is difficult and has proved to be a stumbling block in the evolution of convolutional coding systems. In this article, the situation is improved by describing a set of practical algorithms for computing certain basic things about a convolutional code (among them the degree, the Forney indices, a minimal generator matrix, and a parity-check matrix), which are usually needed before a system using the code can be built. The approach is based on the classic Forney theory for convolutional codes, together with the extended Smith algorithm for polynomial matrices, which is introduced in this article.

    1994-12-31

    The Smith College Secondary Math and Science Outreach Program works collaboratively with front-line educators to encourage young women students of all abilities, especially underrepresented and underserved minorities, to continue studying math and science throughout high school. The program includes three main components: (1) Twenty-five to thirty teams of math/science teachers and guidance counselors participate in a year-long program which begins with a three-day Current Students/Future Scientists and Engineering Workshop. This event includes a keynote address, presentations and workshops by successful women in science and engineering, and hands-on laboratory sessions. Each participant receives a stipend and free room and board. Returning to their schools, the teacher-counselor teams implement ongoing plans designed to counteract gender bias in the sciences and to alert female students to the broad range of math, science, and engineering career choices open to them. A follow-up session in the spring allows the teams to present and discuss their year-long activities. (2) TRI-ON, a day of science for 120 ninth- and tenth- grade girls from schools with a large underserved and underrepresented population, is held in early spring. Girls discover the excitement of laboratory investigation and interact with female college science and math majors. (3) Teaching Internships, initiated in 1991, involve ten to fifteen Smith College math and science majors in teaching in public schools. The teaching interns experience the rewards and challenges of classroom teaching, and they also serve as role models for younger students.

    2008-09-01

    We present an algorithm for computing a Smith form with multipliers of a regular matrix polynomial over a field. This algorithm differs from previous ones in that it computes a local Smith form for each irreducible factor in the determinant separately and then combines them into a global Smith form, whereas other algorithms apply a sequence of unimodular operations to the original matrix row by row (or column by column). The performance of the algorithm in exact arithmetic is reported for several test cases.

    Abstract The taxonomic status of the genus Ambengana Millidge & Russell-Smith, 1992, is revised on the basis of its original description, illustrations and re-examination of the type species. A new synonymy is proposed: Ambengana complexipalpis Millidge & Russell-Smith, 1992 (the type species of Ambengana) syn. n. with Neriene birmanica (Thorell, 1887). Therefore,the genus Ambengana Millidge & Russell-Smith, 1992 syn. n. is synonymized with Neriene Blackwall, 1833. A morphological re-description, diagnosis and comparative illustrations are provided for Neriene birmanica as well. PMID:21594123

    1997-01-31

    We reviewed 215 patients (59 new, 156 from the literature) with Smith-Lemli-Opitz syndrome (SLOS), and found that 95 (44%) had a cardiovascular malformation (CVM). Classifying CVMs by disordered embryonic mechanisms, there were 5 (5.3%) class I (ectomesenchymal tissue migration abnormalities), 56 (58.9%) class II (abnormal intracardiac blood flow), 25 (26.3%) class IV (abnormal extracellular matrix), and 5 (5.3%) class V (abnormal targeted growth). Comparing the frequencies of individual CVMs in this series with a control group (the Baltimore-Washington Infant Study), there were 6 individual CVMs which showed a significant difference from expected values. When frequencies of CVMs in SLOS were analyzed by mechanistic class, classes IV and V were significantly more frequent, and class I significantly less frequent, than the control group. Although CVMs in SLOS display mechanistic heterogeneity, with an overall predominance of class II CVMs, the developmental error appears to favor alteration of the cardiovascular developmental mechanisms underlying atrioventricular canal and anomalous pulmonary venous return. This information should assist the clinical geneticist evaluating a patient with possible SLOS, and should suggest research direction for the mechanisms responsible for the SLOS phenotype. 102 refs., 1 fig., 7 tabs.

    2007-08-27

    Smith River Rancheria (SRR), for some time, has had a strong commitment to attaining energy selfsufficiency, to reduce overall energy costs and concurrently initiate economic development within the community. Early on it was recognized that the development of an energy organization was important and for this reason was made part of the SRR's strategic review not only for economic development but also the reduction of energy costs. Towards this end, SRR retained Werner G. Buehler of W.G. Buehler & Associates to investigate the many phases or steps required to establish such an energy organization and determine, if in fact, it could benefit the Tribe. The basic phases are delineated as: (1) Identify potential sources of wholesale power and transmission paths; (2) Evaluating the various forms of energy organizations; (3) Determining the benefits (and disadvantages) of each form of organization; (4) Gathering costs to organize and operate the selected form or energy organization; (5) Performing an economic analysis of forming and operating an energy organization; and (6) Develop an implementation plan.

To test whether peroxisomes are involved in alternative cholesterol synthesis, we used [1-{sup 14}C]C24:0 for peroxisomal {beta}-oxidation to generate [1-{sup 14}C]acetyl-CoA as cholesterol precursor inside peroxisomes. The HMG-CoA reductase inhibitor lovastatin suppressed cholesterol synthesis from [2-{sup 14}C]acetate and [1-{sup 14}C]C8:0 but not from [1-{sup 14}C]C24:0, implicating a peroxisomal, lovastatin-resistant HMG-CoA reductase. In SLOS fibroblasts lacking DHCR7 activity, no cholesterol was formed from [1-{sup 14}C]C24:0-derived [1-{sup 14}C]acetyl-CoA, indicating that the alternative peroxisomal pathway also requires this enzyme. Our results implicate peroxisomes in cholesterol biosynthesis but provide no link to phenotypic variation in SLOS.

    The behavior phenotype of Smith-Lemli-Opitz syndrome (SLOS) was studied by assessing behavior, social, and communication abilities, sensory hyperreactivity, and the deficits associated with autistic disorder. Fifty-six SLOS subjects, age 0.3 to 32.3 years, were evaluated by multiple age-dependent questionnaires and telephone interviews. Of the 56 subjects, 50 (89%) had a history of repeated self-injury: 30 (54%) bit themselves; 27 (48%) head-banged; and 30 (54%) threw themselves backward in a highly characteristic upper body movement ("opisthokinesis"). Forty-seven of these subjects were also evaluated by direct observation and by direct interview of the parent or caregiver. Of 11 subjects 10 years or older, three (27%) had a stereotypic stretching motion of the upper body accompanied by hand flicking. Additional measures showed sensory hyperreactivity, temperament dysregulation, sleep disturbance, and social and communication deficits. Nine of 17 subjects (53%) met the diagnostic criteria for autistic disorder by the Autism Diagnostic Interview-Revised (ADI-R) algorithm questions [Lord et al., 1993, 1994]. Thus, SLOS is a metabolic disorder that can be associated with autism and other behavioral characteristics that define a distinctive and diagnostically important behavioral disorder. PMID:11223857

    Smith-Magenis syndrome (SMS) is a complex congenital anomaly characterized by craniofacial anomalies, neurological and behavioral disorders. SMS is caused by a deletion in region 17p11.2, which includes the RAI1 gene (90% of cases), or by point mutation in the RAI1 gene (10% of cases). Laboratory diagnosis is through cytogenetic analysis by GTG banding and molecular cytogenetic analysis by FISH. We carried out an active search for patients in Associations of Parents and Friends of Exceptional Children (APAE) of São Paulo and genetic centers in Brazil. Forty-eight patients were screened for mental retardation, craniofacial abnormalities and stereotyped behavior with a diagnosis of SMS. In seven of them, chromosome banding at high resolution demonstrated chromosome 17p11.2 deletions, confirmed by FISH. We also made a meta-analysis of 165 cases reported between 1982 and 2010 to compare with the clinical data of our sample. We demonstrated differences between the frequencies of clinical signs among the cases reported and seven Brazilian cases of this study, such as dental anomalies, strabismus, ear infections, deep hoarse voice, hearing loss, and cardiac defects. Although the gold standard for diagnosis of SMS is FISH, we found that the GTG banding technique developed to evaluate chromosome 17 can be used for the SMS diagnosis in areas where the FISH technique is not available.

    Smith-Magenis syndrome (SMS) is a multiple congenital anomalies and mental retardation syndrome associated with an interstitial deletion of chromosome 17 band p11.2. The incidence of this microdeletion syndrome is estimated to be 1 in 25,000 individuals. Persons with SMS have a distinctive neurobehavioral phenotype that is characterized by aggressive and self-injurious behaviors and significant sleep disturbances. From December 1990 through September 1999, 58 persons with SMS were enrolled in a 5-day multidisciplinary clinical protocol. Developmental assessments consisting of cognitive level and adaptive behavior were completed in 57 persons. Most patients functioned in the mild-to-moderate range of mental retardation. In addition, we report that patients with SMS have low adaptive functioning with relative strengths in socialization and relative weakness in daily living skills. These data were analyzed in light of the molecular extent of the microdeletion within 17p11.2. We found that the level of cognitive and adaptive functioning does depend on deletion size, and that a small percentage of SMS patients have cognitive function in the borderline range. PMID:16775514

    Smith-Magenis syndrome (SMS) is a complex genetic syndrome caused by an interstitial deletion of chromosome 17p11.2. Children and adults with SMS appear to have unique neurobehavioral problems that include: sleep disturbance, self-injurious and maladaptive behaviors, stereotypies, and sensory integration disorders. We gathered retrospective psychotropic use information from parents or other caregivers of 62 individuals with SMS who were asked about use of psychotropic medication from a list of commonly used psychiatric medications. For those drugs identified, respondents were asked to rate the experience with the particular medication using a likert-type scale. Drugs were grouped into seven main categories: (1) stimulants; (2) antidepressants; (3) antipsychotics; (4) sleep aides; (5) mood stabilizers; (6) alpha 2 agonists; and (7) benzodiazepines. Relative frequencies, means and standard deviations pertaining to age and medication effect were derived for each medication category. Six of the seven medication categories examined showed no meaningful deviations from the "no change" score. The benzodiazepine group showed a mild detrimental effect. There were no gender differences in efficacy. Use of psychotropic medication started early in life (mean age 5 years), particularly with sleep aides. Although no medication category was identified as efficacious in SMS, all the categories reported herein may be considered as an option for brief symptomatic relief. PMID:20981776

    Smith-Magenis syndrome (SMS; OMIM 182290) is a neurodevelopmental disorder characterized by a well-defined pattern of anomalies. The majority of cases are due to a common deletion in chromosome 17p11.2 that includes the RAI1 gene. In children with SMS, autistic-like behaviors and symptoms start to emerge around 18 months of age. This study included 26 individuals (15 females and 11 males), with a confirmed deletion (del 17p11.2). Parents/caregivers were asked to complete the Social Responsiveness Scale (SRS) and the Social Communication Questionnaire (SCQ) both current and lifetime versions. The results suggest that 90% of the sample had SRS scores consistent with autism spectrum disorders. Moreover, females showed more impairment in total T-scores (P = 0.02), in the social cognition (P = 0.01) and autistic mannerisms (P = 0.002) subscales. The SCQ scores are consistent to show that a majority of individuals may meet criteria for autism spectrum disorders at some point in their lifetime. These results suggest that SMS needs to be considered in the differential diagnosis of autism spectrum disorders but also that therapeutic interventions for autism are likely to benefit individuals with SMS. The mechanisms by which the deletion of RAI1 and contiguous genes cause psychopathology remain unknown but they provide a solid starting point for further studies of gene-brain-behavior interactions in SMS and autism spectrum disorders.

    Zentall and Smith (2014) have published a comment on Pelé and Sueur (Anim Cogn 16:543-556, 2013) in which they raise two issues, one about the definition of risk and a second concerning the optimality of decisions. When making a choice, subjects are faced not only with several possible alternatives but also with the risk of opting for an unsuitable choice which depends on several variables (context, internal state, knowledge and perception). Although it is true that animals might learn about their environment and adapt their decisions to the context and to their experience, strong constraints make some behavioural traits stable over individual lifetime and even generations. We therefore consider that experience has limited impact on the variability of temporal discounting. These behavioural traits make the difference between perceived and actual risk. If the perceived risk strongly differs from the actual risk, a decision should be considered as suboptimal. If we want to lead individual and collective cognition to a common decision science, it is crucial to use the same definitions for terms implied in decision-making. PMID:25771966

    This study examines the engineering factors and costs associated with the construction, operation, and decommissioning of a high-level nuclear waste repository in salt in the Palo Duro Basin in Deaf Smith County, Texas. The study assumes a repository capacity of 36,000 metric tons of heavy metal (MTHM) of unreprocessed spent fuel and 36,000 MTHM of commercial high-level reprocessing waste, along with 7,020 canisters of defense high-level reprocessing waste and associated quantities or remote- and contact-handled transuranic waste (TRU). With the exception of TRU, all the waste forms are placed in 300- to 1000-year-life carbon-steel waste packages in a collocated waste handling and packaging facility (WHPF), which is also described. The construction, operation, and decommissioning of the proposed repository is estimated to cost approximately $4.64 billion. Costs include those for the collocate WHPF, engineering, and contingency, but exclude waste form assembly and shipment to the site and waste package fabrication and shipment to the site. These costs reflect the relative average wage rates of the region, the relatively easy access to the site, and the relatively weak nature of the salt at this site. Construction would require an estimated 7 to 7.5 years. Engineering factors and costs are not strongly influenced by environmental considerations. 62 refs., 24 figs., 20 tabs.

    STS-103 Mission Specialist Steven L. Smith gets ready to practice driving a small armored personnel carrier that is part of emergency egress training during Terminal Countdown Demonstration Test (TCDT) activities. The tracked vehicle could be used by the crew in the event of an emergency at the pad during which the crew must make a quick exit from the area. The TCDT also provides simulated countdown exercises and opportunities to inspect the mission payloads in the orbiter's payload bay. STS-103 is a 'call-up' mission due to the need to replace and repair portions of the Hubble Space Telescope. Although Hubble is operating normally and conducting its scientific observations, only three of its six gyroscopes are working properly. Four EVA's are planned to make the necessary repairs and replacements on the telescope. The other STS-103 crew members are Commander Curtis L. Brown Jr., Pilot Scott J. Kelly, and Mission Specialists John M. Grunsfeld (Ph.D.), C. Michael Foale (Ph.D.), (Ph.D.), and Claude Nicollier of Switzerland and Jean-Frangois Clervoy of France, who are with the European Space Agency. The mission is targeted for launch Dec. 6 at 2:37 a.m. EST.

    Treatments of sources of Adam Smith's sociological theory of the self and associated ideas in The Theory of Moral Sentiments typically refer to classical antecedents or the work of his teacher Francis Hutcheson or his contemporary David Hume. During the seventeenth century, however, many books on the passions were published in London that arguably constitute an important but neglected source of Smith's treatment of moral sentiments. These works are largely forgotten today but at the time were widely read. They are not philosophical, partly devotional and predominantly psychological. Although Smith does not refer to these works his argument resembles theirs in many places. The importance of the seventeenth-century books on the passions, apart from their role in the history of psychology, is their bearing on contemporary economic practices. In this paper the connections between Smith and one of these books, Thomas Wright's The Passions of the Minde in Generall, are indicated. PMID:15926903

    The approach of Neal and Smith was merged with the advances in pilot modeling by means of optimal control techniques. While confirming the findings of Neal and Smith, a methodology that explicitly includes the pilot's objective in attitude tracking was developed. More importantly, the method yields the required system bandwidth along with a better pilot model directly applicable to closed-loop analysis of systems in any order.

    In February 1983, the US Department of Energy identified a location in Deaf Smith County, Texas, as one of nine potentially acceptable sites for a mined geologic repository for spent nuclear fuel and high-level radioactive waste. The potentially acceptable site was subsequently narrowed to an area of 9 square miles. To determine their suitability, the Deaf Smith site and the eight other potentially acceptable sites have been evaluated in accordance with the DOE's General Guidelines for the Recommendation of Sites for Nuclear Waste Repositories. These evaluations are reported in this draft environmental assessment, which is being issued for public review and comment. The DOE findings and determinations that are based on these evaluations are preliminary and subject to public review and comment. A final EA will be prepared after considering the comments received. On the basis of the evaluations reported in this draft EA, the DOE has found that the Deaf Smith site is not disqualified under the guidelines. The site is in the Permian Basin, which is one of five distinct geohydrologic settings considered for the first repository. This setting contains one other potentially acceptable site - the Swisher site. Although the Swisher site appears to be suitable for site characterization, DOE has concluded that the Deaf Smith site is the preferred site. The DOE finds that the site is suitable for site characterization because the evidence does not support a conclusion that the site will not be able to meet each of the qualifying conditions specified in the guidelines. On the basis of these findings, the DOE is proposing to nominate the Deaf Smith site as one of five sites suitable for characterization. Having compared the Deaf Smith site with the other four sites proposed for nomination, the DOE has determined that the Deaf Smith site is one of the three preferred sites for recommendation to the President as candidates for characterization.

    Recent observations suggest that some high-velocity clouds may be confined by massive dark matter halos. In particular, the proximity and proposed dark matter content of the Smith Cloud make it a tempting target for the indirect detection of dark matter annihilation. We argue that the Smith Cloud may be a better target than some Milky Way dwarf spheroidal satellite galaxies and use γ-ray observations from the Fermi Large Area Telescope to search for a dark matter annihilation signal. No significant γ-ray excess is found coincident with the Smith Cloud, and we set strong limits on the dark matter annihilation cross section assuming a spatially extended dark matter profile consistent with dynamical modeling of the Smith Cloud. Notably, these limits exclude the canonical thermal relic cross section (∼ 3 × 10{sup –26} cm{sup 3} s{sup –1}) for dark matter masses ≲ 30 GeV annihilating via the b b-bar or τ{sup +}τ{sup –} channels for certain assumptions of the dark matter density profile; however, uncertainties in the dark matter content of the Smith Cloud may significantly weaken these constraints.

    Smith-Purcell radiation is a well-known phenomenon, which provides a noninvasive scheme for diagnostics of charged particle beams and is used as an effective source of electromagnetic waves, e.g., in the orotron, the free electron laser, etc. In this paper we develop the theory of Smith-Purcell radiation (SPR) for the little-investigated case of arbitrary angles between the charged particle trajectories and the rulings of a grating. The effect of conical diffraction arising here changes drastically the space distribution of the radiation. By contrast to the only existing approach, described by Haeberle et al. [Phys. Rev. E 55, 4675 (1997)], which requires difficult numerical calculations, we give a fully analytic theory of SPR. Also, in this paper we present for the first time the theory of x-ray Smith-Purcell radiation. Evanescent waves on the surface are shown to lead to strong enhancement of Smith-Purcell radiation, through a resonant mechanism. The results are important for the description of real divergent high-brightness beams and for the development of novel noninvasive diagnostic schemes based on the Smith-Purcell effect.

  2. Groundwater and surface-water interaction within the upper Smith River Watershed, Montana 2006-2010

    The 125-mile long Smith River, a tributary of the Missouri River, is highly valued as an agricultural resource and for its many recreational uses. During a drought starting in about 1999, streamflow was insufficient to meet all of the irrigation demands, much less maintain streamflow needed for boating and viable fish habitat. In 2006, the U.S. Geological Survey, in cooperation with the Meagher County Conservation District, initiated a multi-year hydrologic investigation of the Smith River watershed. This investigation was designed to increase understanding of the water resources of the upper Smith River watershed and develop a detailed description of groundwater and surface-water interactions. A combination of methods, including miscellaneous and continuous groundwater-level, stream-stage, water-temperature, and streamflow monitoring was used to assess the hydrologic system and the spatial and temporal variability of groundwater and surface-water interactions. Collectively, data are in agreement and show: (1) the hydraulic connectedness of groundwater and surface water, (2) the presence of both losing and gaining stream reaches, (3) dynamic changes in direction and magnitude of water flow between the stream and groundwater with time, (4) the effects of local flood irrigation on groundwater levels and gradients in the watershed, and (5) evidence and timing of irrigation return flows to area streams. Groundwater flow within the alluvium and older (Tertiary) basin-fill sediments generally followed land-surface topography from the uplands to the axis of alluvial valleys of the Smith River and its tributaries. Groundwater levels were typically highest in the monitoring wells located within and adjacent to streams in late spring or early summer, likely affected by recharge from snowmelt and local precipitation, leakage from losing streams and canals, and recharge from local flood irrigation. The effects of flood irrigation resulted in increased hydraulic gradients (increased groundwater levels relative to stream stage) or even reversed gradient direction at several monitoring sites coincident with the onset of nearby flood irrigation. Groundwater-level declines in mid-summer were due to groundwater withdrawals and reduced recharge from decreased precipitation, increased evapotranspiration, and reduced leakage in some area streams during periods of low flow. Groundwater levels typically rebounded in late summer, a result of decreased evapotranspiration, decreased groundwater use for irrigation, increased flow in losing streams, and the onset of late-season flood irrigation at some sites. The effect of groundwater and surface-water interactions is most apparent along the North and South Forks of the Smith River where the magnitude of streamflow losses and gains can be greater than the magnitude of flow within the stream. Net gains consistently occurred over the lower 15 miles of the South Fork Smith River. A monitoring site near the mouth of the South Fork Smith River gained (flow from the groundwater to the stream) during all seasons, with head gradients towards the stream. Two upstream sites on the South Fork Smith River exhibited variable conditions that ranged from gaining during the spring, losing (flowing from the stream to the groundwater) during most of the summer as groundwater levels declined, and then approached or returned to gaining conditions in late summer. Parts of the South Fork Smith River became dry during periods of losing conditions, thus classifying this tributary as intermittent. The North Fork Smith River is highly managed at times through reservoir releases. The North Fork Smith River was perennial throughout the study period although irrigation diversions removed a large percentage of streamflow at times and losing conditions persisted along a lower reach. The lowermost reach of the North Fork Smith River near its mouth transitioned from a losing reach to a gaining reach throughout the study period. Groundwater and surface-water interactions occur downstream from the confluence of the North and South Fork Smith Rivers, but are less discernible compared to the overall magnitude of the main-stem streamflow. The Smith River was perennial throughout the study. Monitoring sites along the Smith River generally displayed small head gradients between the stream and the groundwater, while one site consistently showed strongly gaining conditions. Synoptic streamflow measurements during periods of limited irrigation diversion in 2007 and 2008 consistently showed gains over the upper 41.4 river miles of the main stem Smith River where net gains ranged from 13.0 to 28.9 cubic feet per second. Continuous streamflow data indicated net groundwater discharge and small-scale tributary inflow contributions of around 25 cubic feet per second along the upper 10-mile reach of the Smith River for most of the 2010 record. A period of intense irrigation withdrawal during the last two weeks in May was followed by a period (early June 2010 to mid-July 2010) with the largest net increase (an average of 71.1 cubic feet per second) in streamflow along this reach of the Smith River. This observation is likely due to increased groundwater discharge to the Smith River resulting from irrigation return flow. By late July, the apparent effects of return flows receded, and the net increase in streamflow returned to about 25 cubic feet per second. Two-dimensional heat and solute transport VS2DH models representing selected stream cross sections were used to constrain the hydraulic properties of the Quaternary alluvium and estimate temporal water-flux values through model boundaries. Hydraulic conductivity of the Quaternary alluvium of the modeled sections ranged from 3x10-6 to 4x10-5 feet per second. The models showed reasonable approximations of the streambed and shallow aquifer environment, and the dynamic changes in water flux between the stream and the groundwater through different model boundaries.

    Sequence alignment lies at heart of the bioinformatics. The Smith-Waterman algorithm is one of the key sequence search algorithms and has gained popularity due to improved implementations and rapidly increasing compute power. Recently, the Smith-Waterman algorithm has been successfully mapped onto the emerging general-purpose graphics processing units (GPUs). In this paper, we focused on how to improve the mapping, especially for short query sequences, by better usage of shared memory. We performed and evaluated the proposed method on two different platforms (Tesla C1060 and Tesla K20) and compared it with two classic methods in CUDASW++. Further, the performance on different numbers of threads and blocks has been analyzed. The results showed that the proposed method significantly improves Smith-Waterman algorithm on CUDA-enabled GPUs in proper allocation of block and thread numbers. PMID:26339591

    The aim of this review is to perform an overview of the relation between kidney development in different species and new developments in plate tectonics and paleoclimatology, which likely had a remarkable effect on evolution. The review follows the ideas of Homer Smith, but adds new data on the subjects which were unknown in Homer Smith's time. The structure and function of the kidney are a result of hundreds of millions of years of evolution, in which adaptations had to be made in response to environmental demands while maintaining the kidney's integrated function. The ideas of Homer Smith have greatly contributed to our understanding of this process, and continue to be of relevance both for researchers as well as physicians working in the field of kidney disease.

    1982-01-01

    The present investigation is concerned with the development of a better pilot modelling technique via optimal control theory, taking into account concepts concerning 'pilot rating' considered by Neal and Smith (1970). The investigation conducted by Neal and Smith had the objective to provide data on the effects of Flight Control System dynamics and to develop a design criterion capable of pinpointing pilot problem areas encountered in performing a given task. Neal and Smith devised a 'pilot-in-the-loop' analysis capable of showing problem areas in pitch attitude tracking. Unfortunately the employed method has some drawbacks. The current investigation attempts, therefore, to provide an alternate approach which makes use of an optimal-control pilot model. An optimal control model (OCM) had been discussed by Kleinman et al. (1970). It is shown that the alternate approach, based on the OCM, offers some distinct advantages.

    Sequence alignment lies at heart of the bioinformatics. The Smith-Waterman algorithm is one of the key sequence search algorithms and has gained popularity due to improved implementations and rapidly increasing compute power. Recently, the Smith-Waterman algorithm has been successfully mapped onto the emerging general-purpose graphics processing units (GPUs). In this paper, we focused on how to improve the mapping, especially for short query sequences, by better usage of shared memory. We performed and evaluated the proposed method on two different platforms (Tesla C1060 and Tesla K20) and compared it with two classic methods in CUDASW++. Further, the performance on different numbers of threads and blocks has been analyzed. The results showed that the proposed method significantly improves Smith-Waterman algorithm on CUDA-enabled GPUs in proper allocation of block and thread numbers. PMID:26339591

    The Marshall-Smith syndrome is characterised by overgrowth, accelerated skeletal maturation, and dysmorphic facial features, often associated with mental retardation of variable degree. Most of the reported patients died in the first three years of life mainly because of respiratory problems. We describe a 5 year old patient with this rare syndrome, who has optic atrophy and agenesis of the corpus callosum, but has no respiratory problems so far. This observation underlines the clinical variability of the Marshall-Smith syndrome and indicates that life expectancy may be prolonged. Images PMID:8230168

    Grating with Bragg reflectors for the Smith-Purcell free-electron laser is proposed to improve the reflection coefficient, resulting in enhancing the interaction of the surface wave with the electron beam and, consequently, relax the requirements to the electron beam. With the help of particle-in-cell simulations, it has been shown that the usage of Bragg reflectors may improve the growth rate, shorten the time for the device to reach saturation, and lower the start current for the operation of a Smith-Purcell free-electron laser.

    2010-01-01

    Dating from the seventeenth century b.c. the Edwin Smith papyrus is a unique treatise containing the oldest known descriptions of signs and symptoms of injuries of the spinal column and spinal cord. Based on a recent “medically based translation” of the Smith papyrus, its enclosed treasures in diagnostic, prognostic and therapeutic reasoning are revisited. Although patient demographics, diagnostic techniques and therapeutic options considerably changed over time, the documented rationale on spinal injuries can still be regarded as the state-of-the-art reasoning for modern clinical practice.

  10. Theory of the special Smith-Purcell radiation from a rectangular grating

    Liu, Weihao; Li, Weiwei; He, Zhigang; Jia, Qika

    2015-12-01

    The recently uncovered special Smith-Purcell radiation (S-SPR) from the rectangular grating has significantly higher intensity than the ordinary Smith-Purcell radiation (SPR). Its monochromaticity and directivity are also much better. Here we explored the mechanism of the S-SPR by applying the fundamental electromagnetic theory and simulations. We have confirmed that the S-SPR is exactly from the radiating eigen modes of the grating. Its frequency and direction are well correlated with the beam velocity and structure parameters, which indicates its promising applications in tunable wave generation and beam diagnostic.

    Hawgood, Barbara J

    2009-05-01

    James Edward Smith's interest in botany led him to enter medicine at Edinburgh in 1781. Smith was continuing his medical studies in London when Sir Joseph Banks (1743-1820) suggested to him that he should purchase the collection of the famous Swedish naturalist Carl Linnaeus that had just been offered to Banks. Smith bought the Linnean Collection and Library in 1784. In 1786 he was awarded the degree of Doctor of Medicine from Leiden. In 1788 Smith, with two associates, founded the Linnean Society of London and became President for life. Smith turned from medicine to natural history as a lecturer and writer. During his lifetime he produced numerous botanical works of high value, including The English Flora (1824-28), and he did much to popularize botany. PMID:19401517

    PubMed Central

    Choi, Sang Yoon

    2013-01-01

    Background: Recently, a great deal of attention has been directed toward the use of crude extracts from natural products for cosmetic applications. Thus, we performed a series of experiments to investigate skin depigmenting properties of a crude extract that was derived from a traditional Korean medicinal plant. Materials and Methods: In this study, the depigmentational potency of Cyrtomium fortunei J. Smith was investigated. The inhibitory effects of the root of Cyrtomium fortunei J. Smith extract on melanin production were evaluated by assessing its tyrosinase inhibitory effects, melanin production-inhibitory properties in melan-a cells and depigmenting ability in brown guinea pig skin. Results: The methanolic extract of the root of Cyrtomium fortunei J. Smith appeared to inhibit tyrosinase activity and melanin production in melan-a cells. In addition, this extract exhibited depigmenting ability on Ultra violet-induced hyper pigmentation in brown guinea pig skin. Conclusion: These results suggested that root of Cyrtomium fortunei J. Smith might prove useful in treating skin hyperpigmentation associated with excess sun-exposure. PMID:23930006

    An orotronlike feedback can provide a significant increase in the selectivity and power of frequency-multiplied Smith-Purcell radiation of the electron bunches formed in the course of self-excitation of a grating surface eigenmode. This method looks promising for efficient terahertz generation from both weakly and mildly relativistic electron beams.

  9. What’s in a Surname? Physique, Aptitude, and Sports Type Comparisons between Tailors and Smiths

    PubMed Central

    2015-01-01

    Combined heredity of surnames and physique, coupled with past marriage patterns and trade-specific physical aptitude and selection factors, may have led to differential assortment of bodily characteristics among present-day men with specific trade-reflecting surnames (Tailor vs. Smith). Two studies reported here were partially consistent with this genetic-social hypothesis, first proposed by Bäumler (1980). Study 1 (N = 224) indicated significantly higher self-rated physical aptitude for prototypically strength-related activities (professions, sports, hobbies) in a random sample of Smiths. The counterpart effect (higher aptitude for dexterity-related activities among Tailors) was directionally correct, but not significant, and Tailor-Smith differences in basic physique variables were nil. Study 2 examined two large total-population-of-interest datasets (Austria/Germany combined, and UK: N = 7001 and 20532) of men’s national high-score lists for track-and-field events requiring different physiques. In both datasets, proportions of Smiths significantly increased from light-stature over medium-stature to heavy-stature sports categories. The predicted counterpart effect (decreasing prevalences of Tailors along these categories) was not supported. Related prior findings, the viability of possible alternative interpretations of the evidence (differential positive selection for trades and occupations, differential endogamy and assortative mating patterns, implicit egotism effects), and directions for further inquiry are discussed in conclusion.

  5. Neurologic and developmental features of the Smith-Magenis syndrome (del 17p11.2).

    PubMed

    Gropman, Andrea L; Duncan, Wallace C; Smith, Ann C M

    2006-05-01

    The Smith-Magenis syndrome is a rare, complex multisystemic disorder featuring, mental retardation and multiple congenital anomalies caused by a heterozygous interstitial deletion of chromosome 17p11.2. The phenotype of Smith-Magenis syndrome is characterized by a distinct pattern of features including infantile hypotonia, generalized complacency and lethargy in infancy, minor skeletal (brachycephaly, brachydactyly) and craniofacial features, ocular abnormalities, middle ear and laryngeal abnormalities including hoarse voice, as well as marked early expressive speech and language delays, psychomotor and growth retardation, and a 24-hour sleep disturbance. A striking neurobehavioral pattern of stereotypies, hyperactivity, polyembolokoilamania, onychotillomania, maladaptive and self-injurious and aggressive behavior is observed with increasing age. The diagnosis of Smith-Magenis syndrome is based upon the clinical recognition of a constellation of physical, developmental, and behavioral features in combination with a sleep disorder characterized by inverted circadian rhythm of melatonin secretion. Many of the features of Smith-Magenis syndrome are subtle in infancy and early childhood, and become more recognizable with advancing age. Infants are described as looking "cherubic" with a Down syndrome-like appearance, whereas with age the facial appearance is that of relative prognathism. Early diagnosis requires awareness of the often subtle clinical and neurobehavioral phenotype of the infant period. Speech delay with or without hearing loss is common. Most children are diagnosed in mid-childhood when the features of the disorder are most recognizable and striking. While improvements in cytogenetic analysis help to bring cases to clinical recognition at an earlier age, this review seeks to increase clinical awareness about Smith-Magenis syndrome by presenting the salient features observed at different ages including descriptions of the neurologic and behavioral features. Detailed review of the circadian rhythm disturbance unique to Smith-Magenis syndrome is presented. Suggestions for management of the behavioral and sleep difficulties are discussed in the context of the authors' personal experience in the setting of an ongoing Smith-Magenis syndrome natural history study.

  6. 'Nothing is so soon forgot as pain': Reading Agony in Adam Smith's The Theory of Moral Sentiments.

    PubMed

    Franson, Craig

    2014-01-01

    Giving a rigorous philosophical explanation to the imagination's role in sympathy, Adam Smith's The Theory of Moral Sentiments became a central text in Romantic aesthetics. It not only justified the age's vogue for making suffering an object of artistic pleasure, it treated suffering's affectivity as the very foundation of society. Depicting agony as a spectacle to be read by others, Smith transformed morality into rhetoric, making human subjects into readers of a sentimentalised, textual world. Yet Smith's work restricted the bonds of sympathy, too, following established distinctions between mind and body that helped him to exclude physical pain from sympathetic response. This essay looks to Smith's context in the overlapping philosophical and medical discourses of the Scottish Enlightenment, exploring his moral theory's resonance with the nerve theories of Robert Whytt and William Cullen, then the leading figures in Scotland's rising medical community. Deepening our understanding of Smith's probable sources, it reframes Smith's intellectual and ideological legacy, foregrounding some of the ambivalent cultural and political implications of Smith's troubling censure of physical pain.

    2007-12-01

    While exploring the Chickahominy River in Virginia by canoe in December 1607, Captain John Smith was ambushed by 200 Powhatan Indians and chased into the swamp. Wounded by arrows and mired in the cold mud, Smith surrendered and was led to their chieftain, Opechancanough. Smith played for time. He pulled out his pocket sundial and proceeded to deliver a lecture on astronomy. The Indians marveled at the dancing needle of the magnetic compass, which they could plainly see but not touch because of the glass cover. They apparently thought less of his discourse in a foreign language on the sun, moon, and planets, as within the hour, Smith's captors had him tied to a tree and were ready to shoot him. But then, Opechancanough held the sundial aloft and spared Smith's life. For the next month, Smith was paraded around various Indian villages before being condemned to have his head bashed in. Pocahontas, however, threw herself across Smith's body in order to save his life. This legendary episode reveals more than Smith's ingenuity. His compass sundial, shaped and marked like a celestial globe, was a microcosm of his universe. It embodied the belief that the smallest things mirrored the large, that number was the key to God's creation, and that by means of mathematical instruments, men could dominate that world (or at least extricate themselves from tight spots!). This paper will examine the astronomical ideas and instruments on which these beliefs were based, and show how ultimately, Smith's sundial also represented the clash of two cosmologies-that of the Indians and European settlers.

  8. Coherent and tunable light radiation from nanoscale surface plasmons array via an exotic Smith-Purcell effect.

    PubMed

    2015-10-15

    We demonstrate that surface plasmons on a nanoscale metallic array can be transformed into radiation waves via an exotic Smith-Purcell effect. Although the radiation frequency and direction satisfy the Smith-Purcell relation, it is coherent radiation with directions specified, which is essentially different from the ordinary Smith-Purcell radiation. Its radiation spectral density is an order of magnitude higher. By adjusting the material and structure of the array, the radiation frequency can be tuned from an infrared to ultraviolet region. Its remarkable advantages in intensity, coherence, tunability, and miniature size indicate new prospects in developing nanoscale light sources and related techniques. PMID:26469568

    2016-03-01

    The special Smith-Purcell radiation (S-SPR), which is from the radiating eigen modes of a grating, has remarkable higher intensity than the ordinary Smith-Purcell radiation. Yet in previous studies, the gratings were treated as perfect conductor without considering the surface plasmon polaritons (SPPs) which are of significance for the nano-scale gratings especially in the optical region. In present paper, the rigorous theoretical investigations on the S-SPR from a nano-grating with SPPs taken into consideration are carried out. The dispersion relations and radiation characteristics are obtained, and the results are verified by simulations. According to the analyses, the tunable light radiation can be achieved by the S-SPR from a nano-grating, which offers a new prospect for developing the nano-scale light sources.

  10. Collision of the Smith Cloud and its dark matter halo with the magnetized Galactic disk

    Galyardt, Jason; Shelton, Robin L.

    2015-01-01

    The Smith Cloud is a massive High Velocity Cloud (HVC) that may have passed through the Milky Way disk in the recent past. Previous studies using hydrodynamic simulations suggest that a dark matter halo may have provided the confinement neccessary for the Smith Cloud to survive passage through the Galactic corona and disk. However, the models of the Galaxy that were used in these studies did not include a magnetic field, while magnetic fields are known to have confining properties. Other studies have shown that the Galactic magnetic field can inhibit mass exchange between the corona and the disk due to magnetic field compression. We extend upon these studies via FLASH magnetohydrodynamic simulations to consider the effects of a Galactic magnetic field on an infalling, dark matter confined HVC.

    2015-03-15

    In this paper, a novel method of getting the dispersion relations in planar grating with arbitrary grooves for terahertz Smith-Purcell radiation is investigated analytically. The continuous profile of the groove is approximately replaced by a series of rectangular steps. By making use of field matches method and the continuity of transverse admittance, the universal dispersion equation for grating with arbitrarily shaped grooves is derived. By solving the dispersion equation in presence of electron beam, the growth rate is obtained directly and the dependence on beam parameters is analyzed. Comparisons of the dispersion characteristics among some special groove shapes have been made by numerical calculation. The results show that the rectangular-step approximation method provides a novel approach to obtain the universal dispersion relation for grating with arbitrary grooves for Smith-Purcell radiation.

    We investigate quantum phases and Wigner-Smith time delays in photoionization and photorecombination of valence electrons of argon using Kohn-Sham time-dependent local density approximation (TDLDA) with the Leeuwen and Baerends exchange-correlation functional. Numerical results for the phases at respective 3p and 3s Cooper minima show opposite variations resulting from the correlation that is based on mutual couplings between 3p and 3s channels. Computed attosecond Wigner-Smith time delays show excellent agreements with two recent independent experiments on argon that measured the relative 3s-3p time delay in photoionization and the delay in 3p photorecombination.

  13. Finding revelation in anthropology: Alexander Winchell, William Robertson Smith and the heretical imperative.

    PubMed

    Livingstone, David N

    2015-09-01

    Anthropological inquiry has often been considered an agent of intellectual secularization. Not least is this so in the sphere of religion, where anthropological accounts have often been taken to represent the triumph of naturalism. This metanarrative, however, fails to recognize that naturalistic explanations could sometimes be espoused for religious purposes and in defence of confessional creeds. This essay examines two late nineteenth-century figures--Alexander Winchell in the United States and William Robertson Smith in Britain--who found in anthropological analysis resources to bolster rather than undermine faith. In both cases these individuals found themselves on the receiving end of ecclesiastical censure and were dismissed from their positions at church-governed institutions. But their motivation was to vindicate divine revelation, in Winchell's case from the physical anthropology of human origins and in Smith's from the cultural anthropology of Semitic ritual.

    This report presents a preliminary analysis of possible highway and rail transportation routes within Texas, Oklahoma, and New Mexico for shipments of spent fuel to the candidate repository site in Deaf Smith County, Texas. Two cases are examined for highway shipments. The initial case analyzes shipments following the Department of Transportation's HM-164 regulations for shipment of spent fuel. The second case analyzes normal commercial routes. Three rail cases are also examined. Each case analyzes potential routes that would be used based for different access spurs into the repository site. Two appendices are included which examine additional scenarios generated by restricting routes from passing through various metropolitan areas. The major finding is that most shipments to the Deaf Smith site will pass through Amarillo, Texas. There are few, if any, feasible alternative routes which would significantly reduce the amount of traffic passing through Amarillo.

    1983-01-01

    The CERETRON microwave generator concept relies on the conversion of intense relativistic electron beam (REB) energy into highpower microwave emission through the Smith-Purcell effect. We report initial results from experiments with the production of Ka-band Smith-Purcell radiation generated by a 50-kA, 2.8-MeV beam propagated through a cylindrical transmission grating with lambda/sub 0/ = 1 cm. These experiments were performed without a quasi-optical resonator, and the output was limited by breakdown of the grating and by limited access through the 90-kG magnet coil. Nevertheless, the measured power output from these initial experiments was about 7 kW in the Ka band.

  20. Discovery and antitumor activities of constituents from Cyrtomium fortumei (J.) Smith rhizomes

    2013-01-01

    Background Cyrtomium fortumei (J.) Smith is an important Chinese herbal medicine because of its biological functions. However, systematic and comprehensive studies on the phytochemicals from Cyrtomium fortumei (J.) Smith and their bioactivity are limited. Results Using the bioassay-guided technique, the ethyl acetate and n-BuOH extracts of the rhizomes of Cyrtomium fortumei (J.) Smith were shown to exhibit good antitumor activities, consequently leading to the isolation of 23 compounds. All compounds were isolated from the plant for the first time. The inhibitory activities of these compounds were investigated on tumor cells MGC-803, PC3, and A375 in vitro by MTT (thiazolyl blue tetrazolium bromide) assay, and the results showed that pimpinellin (3) had potent cytotoxic activities against the three cell lines, with the IC50 values of 14.4 ± 0.3 μM, 20.4 ± 0.5 μM, and 29.2 ± 0.6 μM, respectively. The mechanism of the antitumor action indicated that pimpinellin inhibited the growth of MGC-803 cells via the induction of tumor cell apoptosis, with apoptosis ratio of 27.44% after 72 h of treatment at 20 μM. Conclusions This study suggests that most of the compounds from the roots of Cyrtomium fortumei (J.) Smith could inhibit the growth of human carcinoma cells. Moreover, pimpinellin inhibited the growth of tumor cells via the induction of tumor cell apoptosis. PMID:23379693

    1998-08-01

    Smith-Lemli-Opitz syndrome is a frequently occurring autosomal recessive developmental disorder characterized by facial dysmorphisms, mental retardation, and multiple congenital anomalies. Biochemically, the disorder is caused by deficient activity of 7-dehydrocholesterol reductase, which catalyzes the final step in the cholesterol-biosynthesis pathway-that is, the reduction of the Delta7 double bond of 7-dehydrocholesterol to produce cholesterol. We identified a partial transcript coding for human 7-dehydrocholesterol reductase by searching the database of expressed sequence tags with the amino acid sequence for the Arabidopsis thaliana sterol Delta7-reductase and isolated the remaining 5' sequence by the "rapid amplification of cDNA ends" method, or 5'-RACE. The cDNA has an open reading frame of 1,425 bp coding for a polypeptide of 475 amino acids with a calculated molecular weight of 54.5 kD. Heterologous expression of the cDNA in the yeast Saccharomyces cerevisiae confirmed that it codes for 7-dehydrocholesterol reductase. Chromosomal mapping experiments localized the gene to chromosome 11q13. Sequence analysis of fibroblast 7-dehydrocholesterol reductase cDNA from three patients with Smith-Lemli-Opitz syndrome revealed distinct mutations, including a 134-bp insertion and three different point mutations, each of which was heterozygous in cDNA from the respective parents. Our data demonstrate that Smith-Lemli-Opitz syndrome is caused by mutations in the gene coding for 7-dehydrocholesterol reductase. PMID:9683613

    This is the story of how technology advances allowed the copper industry to realize its full potential. The Peirce-Smith Converting Centennial symposium, to be held at the TMS 2009 Annual Meeting, will celebrate the contributions of two men, William Peirce and E.A.C. Smith, in these advances. However, theirs is representative of a larger story: New, simpler technology releasing the stranglehold of older, more complicated technology, new developments in vessel configuration and design finding alternate routes around dead ends in operability, advances in technique and concepts removing roadblocks of cycle time and capacity, and overall innovation opening up vast new reserves around the world to those companies willing to embrace those improvements. Our story is also one of personalities, stubborn smeltermen versus the innovators, those inside the industry versus those from outside. It is a story of an initial borrowing from the steel industry, but also Peirce and Smith, from the refining end of the copper business, taking the ideas of Baggaley from Pittsburgh’s steel and air-brake industry, who built on what Hollway, Manhès and David, Douglas, and others had done in smelter tests, further to compete with the previous primacy and closely held expertise of the copper smeltermen in Wales. The photos presented illustrate these innovations.

    2010-06-01

    Finding regions of similarity between two very long data streams is a computationally intensive problem referred to as sequence alignment. Alignment algorithms must allow for imperfect sequence matching with different starting locations and some gaps and errors between the two data sequences. Perhaps the most well known application of sequence matching is the testing of DNA or protein sequences against genome databases. The Smith-Waterman algorithm is a method for precisely characterizing how well two sequences can be aligned and for determining the optimal alignment of those two sequences. Like many applications in computational science, the Smith-Waterman algorithm is constrained by the memory access speed and can be accelerated significantly by using graphics processors (GPUs) as the compute engine. In this work we show that effective use of the GPU requires a novel reformulation of the Smith-Waterman algorithm. The performance of this new version of the algorithm is demonstrated using the SSCA#1 (Bioinformatics) benchmark running on one GPU and on up to four GPUs executing in parallel. The results indicate that for large problems a single GPU is up to 45 times faster than a CPU for this application, and the parallel implementation shows linear speed up on up to 4 GPUs.

  6. The Edwin Smith Papyrus: the birth of analytical thinking in medicine and otolaryngology.

    2006-02-01

    The Edwin Smith Papyrus, discovered in 1862 outside of Luxor, Egypt, is the oldest known surgical text in the history of civilization. The surviving scroll, a copy of an earlier text from around 3,000 B.C., gives us remarkable insight into the medical practice of ancient Egyptians in the Nile River bed during the dawn of civilization. The Papyrus is divided into 48 cases, most of which describe traumatic injuries. The text instructs the physician to examine the patient and look for revealing physical signs that may indicate the outcome of the injury. Although in modern medicine we take for granted that the use of physical examination and rational thinking lead to an accurate conclusion, 5,000 years ago, this was extraordinary. The Edwin Smith Papyrus cast aside the prevailing magic and mysticism of that time in favor of logic and deductive reasoning. As Egyptian civilization declined during the next millennium, the teachings of the Papyrus would be lost. It would not be until 300 B.C. when Hippocrates and his disciples in ancient Greece would once again revive logic in medical thinking and teaching. It is believed that the ancient Greeks had knowledge of the contents of the Edwin Smith Papyrus and its teachings and used them as the basis for their writings. As Europe entered the Dark Ages, so did medicine yet again, reverting to spells and prayers instead of judgment and reason. Although Hippocrates teachings were recognized by some scholars during the Middle Ages, they did not make up the basis for mainstream medical knowledge. With the dawn of the Renaissance, medicine would finally purge itself of its past supernatural foundation. Hippocratic teachings were used to form the basis of modern medicine, and medical pioneers in the 17 century studied the ancient Greek texts as the origin for their ideas. Many of the concepts physicians and patients today take as common knowledge originated in the Edwin Smith Papyrus. The authors attempt to uncover some of these fundamental ideas and trace them through time until their incorporation in our modern medical knowledge base. It is the rational, logical, and advanced thinking exhibited in the Edwin Smith Papyrus that mandates its respect from modern otolaryngologists and all physicians alike. PMID:16467701

  7. Collisions between Dark Matter Confined High Velocity Clouds and Magnetized Galactic Disks: The Smith Cloud

    NASA Astrophysics Data System (ADS)

    Galyardt, Jason; Shelton, Robin L.

    2016-01-01

    The Galaxy’s population of High Velocity Clouds (HVCs) may include a subpopulation that is confined by dark matter minihalos and falling toward the Galactic disk. We present the first magnetohydrodynamic simulational study of dark-matter-dominated HVCs colliding with a weakly magnetized galactic disk. Our HVCs have baryonic masses of 5 × 106M⊙ and dark matter minihalo masses of 0, 3 × 108, or 1 × 109 M⊙. They are modeled on the Smith Cloud, which is said to have collided with the disk 70 Myr ago. We find that, in all cases, the cloud’s collision with the galactic disk creates a hole in the disk, completely disperses the cloud, and forms a bubble-shaped structure on the far side of the disk. In contrast, when present, the dark matter minihalo continues unimpeded along its trajectory. Later, as the minihalo passes through the bubble structure and galactic halo, it accretes up to 6.0 × 105 M⊙ in baryonic material, depending on the strengths of the magnetic field and minihalo gravity. These simulations suggest that if the Smith Cloud is associated with a dark matter minihalo and collided with the Galactic disk, the minihalo has accreted the observed gas. However, if the Smith Cloud is dark-matter-free, it is on its first approach toward the disk. These simulations also suggest that the dark matter is most concentrated either at the head of the cloud or near the cloud, depending upon the strength of the magnetic field, a point that could inform indirect dark matter searches.

  8. Surgical treatment of scoliosis in Smith-Magenis syndrome: a case report

    PubMed Central

    2010-01-01

    Introduction Smith-Magenis syndrome is a rare genetic condition associated with scoliosis in approximately 30% of cases. There is limited information in the literature on the treatment of scoliosis and the surgical outcome in patients with this condition. Characteristic features of the syndrome, such as the presence of congenital heart and renal disease, inherent immunodeficiency, as well as severe behavioural disorders may complicate the surgical treatment of patients. Case presentation We present the case of an 11-year-old British Caucasian girl with Smith-Magenis syndrome who developed a severe, progressive thoracic and lumbar scoliosis measuring 85 and 80, respectively. She had no cardiac or renal anomalies. Brace treatment was unsuccessful to prevent deterioration of the scoliosis. Both curves were rigid on supine maximum side-bending and traction radiographs. Our patient underwent a posterior spinal arthrodesis with pedicle screw/hook and rod instrumentation and autologous iliac crest graft, supplemented by allograft bone. She had an uneventful postoperative course other than the development of a small wound dehiscence which required resuturing with no signs of a wound infection. A good correction of both scoliotic curvatures to 45 and 40 and a balanced spine in both the coronal and sagittal planes was achieved. Follow-up to skeletal maturity (4 years post-surgery) showed no loss of deformity correction, no detected pseudarthrosis and a good clinical outcome. Conclusion Patients with Smith-Magenis syndrome can develop a severe scoliosis that may require surgical treatment. Congenital cardiac and renal disease, immunodeficiency and severe behavioural problems can affect the surgical outcome following spinal arthrodesis and need to be taken into consideration. Our case demonstrates that surgical correction of the deformity can be performed safely on this group of patients, with a good outcome and an uncomplicated postoperative course. PMID:20181043

    Currently the physical exercise in whole body vibration platforms has become popular among people that frequenting gym and physiotherapy clinics. The objective of this study was to compare the oxygen consumption in the squat exercise performed at Smith Machine and squat performed on the vibration platform following the protocols usually referenced in both types of exercise (with load of 70% in the Smith Machine and unloaded on the vibration platform). The sample consisted of eight male subjects, with a mean age of 22.75 ± 2.05 years, an average body mass 74.50 ± 9.50kg, a stature of 1.79 ± 0.63m and estimated body fat percentage of 5.01 ± 0.94%. The volunteers performed two exercise sessions, one in the Smith Machine (AGSM) and the other on the vibration platform (AGPP). Each session consisted in 5 sets of 10 repetitions each, with a cadence of 40 beat.min(-1). The load used in the exercise AGSM performance was 70% of 1RM and in the AGPP was used a vibration frequency of 50 Hz, during 60 seconds in high amplitude. The order of the sections was randomized, with seven days apart. The AGPP session presented VO2 absolute = 0.95 ± 0.21L/min, VO2 relative = 12.86 ± 2.43ml/kg/min, and HR = 93.69 ± 10.55 beats/min; and the AGSM session presented VO2 absolute = 1.33 ± 0.29 L/min, VO2 relative = 17.91 ± 2.70 ml/kg/min, and HR = 120.69 ± 14.21 beats/min. The VO2 and HR values of the AGSM session were significantly higher than that found in AGPP session. PMID:26737301

    Infant vaccination using 2-dose priming at 3 and 5 mo of age with a booster at 11–12 mo of age was pioneered in Italy. The 3-5-11 schedule is now used in a growing number of European countries. Infanrix™ hexa (DTPa-HBV-IPV/Hib, GlaxoSmithKline Vaccines) was first licensed for use in 2000 and has been the only pediatric hexavalent vaccine available since 2005. We reviewed available clinical trial data describing the immunogenicity of DTPa-HBV-IPV/Hib when administered at 3, 5, and 11 mo of age, and conducted an analysis of safety using global and Italian post-marketing surveillance data. In Italy, DTPa-HBV-IPV/Hib has a demonstrated safety record extending over a decade of use, it has been associated with record levels of vaccine coverage, and with sustained disease control in vaccinated cohorts. Hexavalent vaccines will continue to contribute to high vaccine coverage in Italy and across Europe. PMID:24004825

    Human radiolabel studies are traditionally conducted to provide a definitive understanding of the human absorption, distribution, metabolism and excretion (ADME) properties of a drug. However, advances in technology over the past decade have allowed alternative methods to be employed to obtain both clinical ADME and pharmacokinetic (PK) information. These include microdose and microtracer approaches using accelerator mass spectrometry, and the identification and quantification of metabolites in samples from classical human PK studies using technologies suitable for non-radiolabelled drug molecules, namely liquid chromatography-mass spectrometry and nuclear magnetic resonance spectroscopy. These recently developed approaches are described here together with relevant examples primarily from experiences gained in support of drug development projects at GlaxoSmithKline. The advantages of these study designs together with their limitations are described. We also discuss special considerations which should be made for a successful outcome to these new approaches and also to the more traditional human radiolabel study in order to maximize knowledge around the human ADME properties of drug molecules.

    The United Kingdom (UK) added rotavirus (RV) vaccine (Rotarix GlaxoSmithKline) to the national vaccine schedule in July 2013. During the 2012-2014 rotavirus seasons, children presenting to the Bristol Royal Hospital for Children Emergency Department with gastroenteritis symptoms had stool virology analysis (real-time PCR) and clinical outcome recorded. Nosocomial cases were identified as patients with non-gastroenteritis diagnosis testing positive for rotavirus > 48h after admission. In comparison to average pre-vaccine seasons, in the first year after vaccine introduction there were 48% fewer attendances diagnosed with gastroenteritis, 53% reduction in gastroenteritis admissions and a total saving of 330 bed-days occupancy. There was an overall reduction in number of rotavirus-positive stool samples with 94% reduction in children aged under one year and a 65% reduction in those too old to have been vaccinated. In the first year after the introduction of universal vaccination against rotavirus we observed a profound reduction in gastroenteritis presentations and admissions with a substantial possible herd effect seen in older children. Extrapolating these findings to the UK population we estimate secondary healthcare savings in the first year of ca £7.5 (€10.5) million. Ongoing surveillance will be required to determine the long-term impact of the RV immunisation programme. PMID:26675375

    Among the countries situated in the African meningitis belt, Burkina Faso is usually the one which pays the highest toll to this disease in terms of morbidity and mortality. Until 2002, the causal agent of the epidemic was usually Neisseria meningitidis serogroup A. At the onset of the 2002 epidemic, N. meningitidis W135 was identified as the predominant serogroup by the national reference hospital and the WHO, and this was confirmed by the WHO collaborating centre on meningitis in Oslo, Norway. Due to the nonavailability of an affordable and effective vaccine, the only adequate strategy was proper case management, taking advantage of the sensitivity of the bacteria to the currently used antibiotics. In order to avoid the repetition of such a situation, WHO and GlaxoSmithKline, with the financial support of the Bill and Melinda Gates Foundation, planned and actually realized the production of a trivalent ACW135 vaccine in anticipation of the 2003 epidemic season. In order for the vaccine to be effectively used in the field, it was imperative that various ethical, managerial and technical conditions be fulfilled. The successful use of the trivalent polysaccharide vaccine ACW135 in Burkina Faso during the 2003 outbreak was essentially due to the high level of leadership demonstrated by the national authorities of Burkina Faso, the facilitating role of WHO, the effective coordination of partners and activities, the transparency in the response to the epidemic and the management of the resources.

    To prevent complications that might follow an infection with varicella-zoster virus (VZV), the live attenuated Oka strain (V-Oka) is administered to children in many developed countries. Three vaccine brands (Varivax from Sanofi Pasteur MSD; Varilrix and Priorix-Tetra, both from Glaxo-Smith-Kline) are licensed in Germany and have been associated with both different degrees of vaccine effectiveness and adverse effects. To identify genetic variants in the vaccines that might contribute to rash-associated syndromes, single nucleotide polymorphism (SNP) profiles of variants from the three vaccines and rash-associated vaccine-type VZV from German vaccinees were quantitatively compared by PCR-based pyrosequencing (PSQ). The Varivax vaccine contained an estimated 3-fold higher diversity of VZV variants, with 20% more wild-type (wt) SNPs than Varilrix and Priorix-Tetra. These minor VZV variants in the vaccines were identified by analyzing cloned full-length open reading frame (ORF) orf62 sequences by chain termination sequencing and PSQ. Some of these sequences amplified from vaccine VZV were very similar or identical to those of the rash-associated vaccine-type VZV from vaccinees and were almost exclusively detected in Varivax. Therefore, minorities of rash-associated VZV variants are present in varicella vaccine formulations, and it can be concluded that the analysis of a core set of four SNPs is required as a minimum for a firm diagnostic differentiation of vaccine-type VZV from wt VZV.

    In 2010 the identities of thousands of anti-Plasmodium compounds were released publicly to facilitate malaria drug development. Understanding these compounds' mechanisms of action-i.e., the specific molecular targets by which they kill the parasite-would further facilitate the drug development process. Given that kinases are promising anti-malaria targets, we screened ~14,000 cell-active compounds for activity against five different protein kinases. Collections of cell-active compounds from GlaxoSmithKline (the ~13,000-compound Tres Cantos Antimalarial Set, or TCAMS), St. Jude Children's Research Hospital (260 compounds), and the Medicines for Malaria Venture (the 400-compound Malaria Box) were screened in biochemical assays of Plasmodium falciparum calcium-dependent protein kinases 1 and 4 (CDPK1 and CDPK4), mitogen-associated protein kinase 2 (MAPK2/MAP2), protein kinase 6 (PK6), and protein kinase 7 (PK7). Novel potent inhibitors (IC50 < 1 μM) were discovered for three of the kinases: CDPK1, CDPK4, and PK6. The PK6 inhibitors are the most potent yet discovered for this enzyme and deserve further scrutiny. Additionally, kinome-wide competition assays revealed a compound that inhibits CDPK4 with few effects on ~150 human kinases, and several related compounds that inhibit CDPK1 and CDPK4 yet have limited cytotoxicity to human (HepG2) cells. Our data suggest that inhibiting multiple Plasmodium kinase targets without harming human cells is challenging but feasible. PMID:26934697

    Malaria remains an important health threat to non-immune travelers with the explosive growth of global travel. Populations at high risk of acquiring malaria infections include once semi-immune travelers who visit friends and relatives, military forces, business travelers and international tourists with destinations to sub-Saharan Africa, where malaria transmission intensity is high. Most malaria cases have been associated with poor compliance with existing preventive measures, including chemoprophylaxis. High risk groups would benefit immensely from an efficacious vaccine to protect them against malaria infection and together make up a sizable market for such a vaccine. The attributes of an ideal malaria vaccine for non-immune travelers and military personnel include a protective efficacy of 80% or greater, durability for at least 6 months, an acceptable safety profile and compatibility with existing preventive measures. It is very likely that a malaria vaccine designed to effectively prevent infection and clinical disease in the non-immune traveler and military personnel will also protect semi-immune residents of malaria-endemic areas and contribute to malaria elimination by reducing or blocking malaria transmission. The RTS,S vaccine (GlaxoSmithKline) and the PfSPZ Vaccine (Sanaria Inc) are the leading products that would make excellent vaccine candidates for these vulnerable populations. PMID:26458800

    A public-private partnership (PPP) involving Stellenbosch University in South Africa and GlaxoSmithKline (GSK) has benefited both research and a local community where tuberculosis (TB) is endemic. The venture, part of GSK's Action TB programme, enabled the University's Desmond Tutu TB Centre to establish an epidemiological field site in two suburbs of Cape Town where the annual risk of TB infection is 3.5%. Collaboration between the centre and GSK focused on the development of a surrogate marker model able to predict patient outcome with relative accuracy. Such models may be useful tools for diagnosis/prognosis and for shortening clinical trials of novel TB agents. Other research findings stemming from the Action TB partnership suggest that exogenous reinfection is responsible for the majority of relapse cases and that adults often have infection with multiple strains. The local community has been empowered by the implementation of the Directly Observed Treatment, Short-course (DOTS) programme and benefited from improved education about health in general and TB in particular. The centre has also provided employment for many local people in field work and other roles. Meanwhile, national and international publicity about the centre's work has aided in generating the essential political will to allocate resources and shape healthcare priorities, benefiting this impoverished community.

    Erectile dysfunction (ED) is a common medical condition that affects the sexual life of millions of men. At present, first-line oral pharmacotherapy for most patients with ED is a phosphodiesterase type 5 (PDE-5) inhibitor, of which three are currently available worldwide. Sildenafil (Viagra, Pfizer) has a very satisfactory efficacy-safety profile in all patient categories. The first PDE-5 inhibitor to reach the market, it is now the most widely prescribed oral agent for ED. Tadalafil (Cialis, Lilly ICOS) and vardenafil (Levitra, Bayer/GlaxoSmithKline) were introduced to the European Union and the US in 2003 and 2004, respectively. These three PDE-5 inhibitors share many characteristics, but each has unique features. This review describes the chemical, pharmacologic and clinical features of sildenafil, vardenafil and tadalafil as oral first-line treatments for ED. First, we describe the physiology of penile erection and PDE-5 inhibitor pharmacology, including chemistry, PDE selectivity, pharmacokinetics, and possible drug interactions. We then summarize data on the efficacy and safety profiles of the three PDE-5 inhibitors for the treatment of ED in the general population, in patients with diabetes mellitus and in men that have undergone bilateral nerve-sparing retropubic radical prostatectomy.

    Erectile dysfunction (ED) is a common medical condition that affects the sexual life of millions of men worldwide. Many drugs are now available for the treatment of ED, with oral pharmacotherapy representing the first-line option for most patients. Sildenafil citrate, an inhibitor of the enzyme phosphodiesterase type 5 (PDE5), is the most widely prescribed oral agent and has a very satisfactory efficacy-safety profile in all patient categories. Tadalafil (Cialis; Eli Lilly & Co., ICOS) and vardenafil (Levitra; Bayer Pharmaceuticals, GlaxoSmithKline) are new PDE5 inhibitors that have recently been approved worldwide. Both have been associated with significant positive efficacy-safety profiles. Apomorphine sublingual is a dopamine D1 and D2 receptor agonist, which has been approved for marketing in Europe. It is best selected for treating patients with mild-to-moderate ED, but it is seldom used in clinical practice due to its limited efficacy and side effects, particularly nausea. Patients who do not respond to oral pharmacotherapy or who are unable to use it are appropriate candidates for intracavernosal and intraurethral therapy. The efficacy of second-line treatment is high, but the attrition rate remains significant. For the purpose of this review, clinical and pharmacological analysis focuses on the recent advances in the field of oral therapy, including PDE5 inhibitors and sublingual apomorphine. PMID:15155143

    This review describes the pharmacologic, pharmacokinetic, and pharmacodynamic properties of albiglutide, as well as its clinical efficacy and safety. Albiglutide is a novel, once-weekly, injectable glucagon-like peptide-1 receptor agonist for the treatment of type 2 diabetes. The European Commission recently granted marketing authorization for the drug in the European Union and on April 15, 2014, the US Food and Drug Administration approved albiglutide (Tanzeum™ [GlaxoSmithKline LLC, Wilmington, DE, USA]) to improve glycemic control in adults with type 2 diabetes. Albiglutide has been studied in Phase I, II, and III clinical trials. In the Phase III clinical trials, known as the Harmony series, weekly dosing of albiglutide demonstrated reductions in fasting plasma glucose, postprandial plasma glucose, and glycated hemoglobin, and was associated with weight loss. In all phases of the clinical trials, albiglutide administered once weekly showed a safety and tolerability profile similar to that of placebo, with mild gastrointestinal-related complaints and injection site erythema being the most commonly encountered adverse effects. Compared with pioglitazone and liraglutide, albiglutide has been shown to be clinically less effective. However, it offers the benefit of weight loss that pioglitazone does not, with fewer gastrointestinal side effects than liraglutide. As guidelines continue to advocate for patient-centered treatment strategies, once-weekly albiglutide will be an important addition to the growing armamentarium of treatment options for adults with type 2 diabetes needing target glycemic control.

    Application of the strategic leverage of Resource Based View of the Firm (RBV) directly advocates that a company's competitive advantage is derived from its ability to assemble and exploit an appropriate combination of resources (both tangible and intangible assets). The three companies that were selected were Pittsburgh-based companies that were within relatively easy access, representing healthcare service-related industries, and can be reviewed for the principles of the RBV. The particular firms represented a variety of establishments and included Baptist Homes (a long-term care facility), University of Pittsburgh Medical Center (UPMC)(a provider of hospital and other health services), and GlaxoSmithKline, Consumer Healthcare, North America (GSK-CHNA)(a global provider of healthcare products and services). Through the case studies, it was found that not all intangible assets are strategic, and by extension, not all measures of reputation are strategic either. For an intangible asset to be considered strategic, in this case reputation, it must be valuable, rare, imperfectly imitable, and non-substitutable. PMID:19064477

    Bayer is developing vardenafil, an orally active phosphodiesterase (PDE) 5 inhibitor for the potential treatment of erectile dysfunction (ED) [314382]. NDAs were filed in September 2001 in the US and Mexico [423096], and vardenafil was submitted for Canadian approval in October 2001. As of November 2001, Bayer was expecting a response from the FDA in the second half of 2002 [429499]; the EMEA accepted a filing in January 2002, following a December 2001 submission [438163]. By October 2000, phase III trials were underway in Japan [384751] and by December 2001, a Japanese NDA had been filed; at the same time an application was filed in South Africa [426526], [433060]. At this time Japanese launch was expected in 2003 [434758]. By February 2001, Bayer was also investigating a nasal formulation of vardenafil for the potential treatment of erectile dysfunction [397608]. In November 2001, Bayer and GlaxoSmithKline signed a worldwide copromotion agreement for vardenafil, under which Bayer was to be responsible for all regulatory work required to obtain approval [429499]. In February 1999, Lehman Brothers predicted a 10% probability that vardenafil would reach the market, with launch in 2002. Peak Japanese sales of US$600 million were predicted for 2014 [319225]. In May 2000, Bayer predicted peak sales of Euro900 million [397137]. In July 2001, Lehman Brothers predicted a 75% chance that vardenafil would reach the market, and forecast peak sales of US $0.85 billion worldwide; the analyst also speculated that Bayer would seek a comarketing partner [414766].

    As two-thirds of the US population is overweight or obese, new strategies are needed to help individuals safely and effectively lose weight. One option is to use dietary supplements, but not all supplements that are touted for weight loss have published clinical support for efficacy. The purpose of this article was to identify all published articles on dietary supplements for weight loss. Effectiveness of these supplements was defined as promoting 1-2 lb of weight loss each week. Although several dozen different dietary supplements are sold, only 14 published studies were identified. Four individual ingredients and three blends of ingredients were considered to be effective. Additionally, we compared weight loss from these dietary supplements to over-the-counter (OTC) orlistat (alli™, GlaxoSmithKline, Brentford, UK). Five single ingredients and three blends of ingredients produced more weight loss than OTC orlistat. Persons who use dietary supplements for weight management, counsel patients on how to lose weight, and retailers who sell dietary supplements, should become familiar with those supplements only that are effective at producing weight loss to assure the best results.

    2016-01-01

    A kinase-targeting cell-based high-throughput screen (HTS) against Trypanosoma brucei was recently reported, and this screening set included the Published Kinase Inhibitor Set (PKIS). From the PKIS was identified 53 compounds with pEC50 ≥ 6. Utilizing the published data available for the PKIS, a statistical analysis of these active antiparasitic compounds was performed, allowing identification of a set of human kinases having inhibitors that show a high likelihood for blocking T. brucei cellular proliferation in vitro. This observation was confirmed by testing other established inhibitors of these human kinases and by mining past screening campaigns at GlaxoSmithKline. Overall, although the parasite targets of action are not known, inhibitors of this set of human kinases displayed an enhanced hit rate relative to a random kinase-targeting HTS campaign, suggesting that repurposing efforts should focus primarily on inhibitors of these specific human kinases. We therefore term this statistical analysis-driven approach “preferred lead repurposing”. PMID:26998514

    The pharmaceutical industry remains under huge pressure to address the high attrition rates in drug development. Attempts to reduce the number of efficacy- and safety-related failures by analysing possible links to the physicochemical properties of small-molecule drug candidates have been inconclusive because of the limited size of data sets from individual companies. Here, we describe the compilation and analysis of combined data on the attrition of drug candidates from AstraZeneca, Eli Lilly and Company, GlaxoSmithKline and Pfizer. The analysis reaffirms that control of physicochemical properties during compound optimization is beneficial in identifying compounds of candidate drug quality and indicates for the first time a link between the physicochemical properties of compounds and clinical failure due to safety issues. The results also suggest that further control of physicochemical properties is unlikely to have a significant effect on attrition rates and that additional work is required to address safety-related failures. Further cross-company collaborations will be crucial to future progress in this area. PMID:26091267

    Oncogenic NRAS mutations are highly prevalent in acute myeloid leukemia (AML). Genetic analysis supports the hypothesis that NRAS mutations cooperate with antecedent molecular lesions in leukemogenesis, but have limited independent prognostic significance. Using short hairpin RNAmediated knockdown in human cell lines and primary mouse leukemias, we show that AML cells with NRAS/Nras mutations are dependent on continued oncogene expression in vitro and in vivo. Using the Mx1-Cre transgene to inactivate a conditional mutant Nras allele, we analyzed hematopoiesis and hematopoietic stem and progenitor cells (HSPCs) under normal and stressed conditions and found that HSPCs lacking Nras expression are functionally equivalent to normal HSPCs in the adult mouse. Treating recipient mice transplanted with primary NrasG12D AMLs with 2 potent allosteric mitogen-activated protein kinase kinase (MEK) inhibitors (PD0325901 or trametinib/GlaxoSmithKline 1120212) significantly prolonged survival and reduced proliferation but did not induce apoptosis, promote differentiation, or drive clonal evolution. The phosphatidylinositol 3-kinase inhibitor GDC-0941 was ineffective as a single agent and did not augment the activity of PD0325901. All mice ultimately succumbed to progressive leukemia. Together, these data validate oncogenic N-Ras signaling as a therapeutic target in AML and support testing combination regimens that include MEK inhibitors. PMID:25361812

    In 2009, the Australian Government's National Sexually Transmitted Infection Prevention Program launched a multi-million dollar sexual health campaign targeting young people. We assessed campaign recognition among a community sample of young people. Individuals aged 16-29 years self-completed a questionnaire at a music festival. Participants were asked whether they recognised the campaign image and attempted to match the correct campaign message. Recognition of two concurrent campaigns, GlaxoSmithKline's The Facts genital herpes campaign (targeting young women) and the Drama Downunder campaign (targeting gay men) were assessed simultaneously. Among 471 participants, just 29% recognised the National Sexually Transmitted Infection Prevention Program campaign. This compared to 52% recognising The Facts and 27% recognising Drama Downunder. Of 134 who recognised the National Sexually Transmitted Infection Prevention Program campaign, 27% correctly recalled the campaign messages compared to 61% of those recognising the Facts campaign, and 25% of those recognising the Drama Downunder campaign. There was no difference in National Sexually Transmitted Infection Prevention Program campaign recognition by gender or age. Campaign recognition and message recall of the National Sexually Transmitted Infection Prevention Program campaign was comparatively low. Future mass media sexual health campaigns targeting young people can aim for higher recognition and recall rates than that achieved by the National Sexually Transmitted Infection Prevention Program campaign. Alternative distribution channels and message styles should be considered to increase these rates. PMID:25006041

    In the interest of identification of new kinase-targeting chemotypes for target and pathway analysis and drug discovery in Trypanosomal brucei, a high-throughput screen of 42,444 focused inhibitors from the GlaxoSmithKline screening collection was performed against parasite cell cultures and counter-screened against human hepatocarcinoma (HepG2) cells. In this way, we have identified 797 sub-micromolar inhibitors of T. brucei growth that are at least 100-fold selective over HepG2 cells. Importantly, 242 of these hit compounds acted rapidly in inhibiting cellular growth, 137 showed rapid cidality. A variety of in silico and in vitro physicochemical and drug metabolism properties were assessed, and human kinase selectivity data were obtained, and, based on these data, we prioritized three compounds for pharmacokinetic assessment and demonstrated parasitological cure of a murine bloodstream infection of T. brucei rhodesiense with one of these compounds (NEU-1053). This work represents a successful implementation of a unique industrial-academic collaboration model aimed at identification of high quality inhibitors that will provide the parasitology community with chemical matter that can be utilized to develop kinase-targeting tool compounds. Furthermore these results are expected to provide rich starting points for discovery of kinase-targeting tool compounds for T. brucei, and new HAT therapeutics discovery programs. PMID:25340575

    The resurgence of pertussis suggests the need for greater efforts to understand the long-lasting protective responses induced by vaccination. In this paper we dissect the persistence of T memory responses induced by primary vaccination with two different acellular pertussis (aP) vaccines, hexavalent Hexavac® vaccine (Hexavac) (Sanofi Pasteur MSD) and Infanrix hexa® (Infanrix) (Glaxo-SmithKline Biologicals). We evaluated magnitude and duration of T-cell responses to pertussis toxin (PT) by measuring T-cell proliferation, cytokines (IL-2 and IFNγ) production and memory subsets in two groups of children 5 years after primary vaccination. Some of the enrolled children received only primary vaccination, while others had the pre-school boost dose. Positive T-cell responses to PT were detected in 36% of children. Percentage of responsive children, T-cell proliferation and CD4IL-2+ cells were significantly higher in the children primed with Hexavac than in those who received Infanrix vaccine. No major effects of the boost on PT-specific proliferation were observed. Overall, our data documented a persistence of T-cell memory against PT in a minor fraction of children 5 years after primary vaccination. The different responses induced by Hexavac and Infanrix vaccine could rely on differences in PT inactivation process or excipients/adjuvants formulations. PMID:26922984

    Using whole-cell phenotypic assays, the GlaxoSmithKline high-throughput screening (HTS) diversity set of 1.8 million compounds was screened against the three kinetoplastids most relevant to human disease, i.e. Leishmania donovani, Trypanosoma cruzi and Trypanosoma brucei. Secondary confirmatory and orthogonal intracellular anti-parasiticidal assays were conducted, and the potential for non-specific cytotoxicity determined. Hit compounds were chemically clustered and triaged for desirable physicochemical properties. The hypothetical biological target space covered by these diversity sets was investigated through bioinformatics methodologies. Consequently, three anti-kinetoplastid chemical boxes of ~200 compounds each were assembled. Functional analyses of these compounds suggest a wide array of potential modes of action against kinetoplastid kinases, proteases and cytochromes as well as potential host–pathogen targets. This is the first published parallel high throughput screening of a pharma compound collection against kinetoplastids. The compound sets are provided as an open resource for future lead discovery programs, and to address important research questions. PMID:25740547

    The current rates of edentulism have been estimated to be between 7% and 69% of the adult population internationally. In the United States, while the incidence of edentulism continues to decline, rapid population growth coupled with current economic conditions suggest that edentulism and conventional denture use will continue at current or higher numbers. Unfortunately, evidence-based guidelines for the care and maintenance of removable complete denture prostheses do not exist. In 2009, the American College of Prosthodontists (ACP) formed a task force to establish evidence-based guidelines for the care and maintenance of complete dentures. The task force comprised members of the ACP, the Academy of General Dentistry, American Dental Association (ADA) Council on Scientific Affairs, the American Dental Hygienists' Association, the National Association of Dental Laboratories, and representatives from GlaxoSmithKline Consumer Healthcare. The review process included the assessment of over 300 abstracts and selection of over 100 articles meeting inclusion criteria of this review. The task force reviewed synopses of the literature and formulated 15 evidence-based guidelines for denture care and maintenance. These guidelines were reviewed by clinical experts from the participating organizations and were published in February 2011 issue of The Journal of the American Dental Association for widespread distribution to the dental community. These guidelines reflect the views of the task force. PMID:21324026

  13. OOMMPPAA: A Tool To Aid Directed Synthesis by the Combined Analysis of Activity and Structural Data

    2014-01-01

    There is an ever increasing resource in terms of both structural information and activity data for many protein targets. In this paper we describe OOMMPPAA, a novel computational tool designed to inform compound design by combining such data. OOMMPPAA uses 3D matched molecular pairs to generate 3D ligand conformations. It then identifies pharmacophoric transformations between pairs of compounds and associates them with their relevant activity changes. OOMMPPAA presents this data in an interactive application providing the user with a visual summary of important interaction regions in the context of the binding site. We present validation of the tool using openly available data for CDK2 and a GlaxoSmithKline data set for a SAM-dependent methyl-transferase. We demonstrate OOMMPPAA’s application in optimizing both potency and cell permeability and use OOMMPPAA to highlight nuanced and cross-series SAR.

    PRO-051 (GSK-2402968), being developed by GlaxoSmithKline plc, under license from Leiden University Medical Center and Prosensa Therapeutics BV, is a 2'-O-methyl phosphorothioate antisense oligonucleotide for the potential treatment of Duchenne muscular dystrophy (DMD). The PRO-051 oligonucleotide sequence induces skipping of exon 51 of the dystrophin gene by binding to a sequence within the dystrophin pre-mRNA and masking the exon inclusion signals that are used for splicing. Removal of exon 51 from an exon 45 to 50, 47 to 50, 48 to 50, 49 to 50, 50, 52 or 52 to 63 deleted transcript allows restoration of the open reading frame and synthesis of an internally truncated, semi-functional dystrophin protein. By targeting exon 51, approximately 13% of patients with DMD could be treated, the largest proportion of patients that could benefit from targeting a single dystrophin exon. A proof-of-concept clinical trial of PRO-051 in patients with DMD demonstrated that a single intramuscular administration of PRO-051 induced exon skipping within muscle fibers adjacent to the injection site, while biopsies revealed dystrophin expression in treated but not control muscle fibers. At the time of publication, a phase I/IIa trial to evaluate subcutaneous delivery of PRO-051 had been completed, although full results were yet to be published. PMID:20677099

    We have evaluated a novel B-cell FluoroSpot assay for the analysis of antibody responses in healthy individuals vaccinated intramuscularly with Influenza A (H1N1) antigen (Pandemrix®, GlaxoSmithKline). Using the FluoroSpot assay and an ELISpot assay run in parallel for comparison, we measured the frequency of cells secreting antigen-specific as well as total IgG or IgA antibodies seven days post vaccination. The assays were based on high affinity monoclonal antibodies for capture and detection of human IgG and IgA. Whereas conventional ELISpot analyzes IgG- and IgA-secreting B cells separately, fluorescent detection enabled simultaneous enumeration of B cells secreting IgG or IgA in the same well. The FluoroSpot protocol was also simpler as the assay could be performed without the need for an amplifying detection step. While having all the advantages of a conventional ELISpot assay, including high sensitivity, robustness and ease of performance, the FluoroSpot assay adds further value in reducing costs, time and material.

    Narcolepsy type 1 (also named narcolepsy-cataplexy or hypocretin deficiency syndrome) is a rare sleep disorder characterized by excessive daytime sleepiness and cataplexy, plus frequently hypnagogic hallucinations, sleep paralysis and nocturnal sleep disturbances. Narcolepsy type 1 is an immune system-associated disease linked with the destruction of 70.000-90.000 hypocretin neurons notably involved in wakefulness. Among narcoleptic patients, 98% are positive for HLA-DQB1*06:02, a HLA class II allele, against 20-25% in general population. Individuals carrying HLA-DQB1*06:02 have an extraordinary risk to develop narcolepsy (odd ratio: 251). Other genes involved in CD4+ T cells and immune system activation as T-cell receptor α are also associated with narcolepsy. The development of the disease is linked with environmental factors such as influenza and streptococcal infections. Narcolepsy type 1 incidence also increased in Europe following the use of Pandemrix, a 2009 H1N1 AS03-adjuvanted vaccine manufactured by GlaxoSmithKline. Interestingly, such increase was not observed with Arepanrix, another vaccine developed by GSK very similar to Pandemrix. PMID:25537044

    Influenza viruses cause annual winter epidemics in temperate regions, with significant morbidity, mortality and economical impact. Fluarix is a split, trivalent, inactivated vaccine, manufactured from highly purified, egg-grown influenza viruses by GlaxoSmithKline. In 2005, Fluarix underwent accelerated approval for use in adults by the US FDA following a US-based, randomized, placebo-controlled trial that established its safety and immunogenicity in adults. The vaccine has been licensed in Europe since 1992 for all age groups. Multiple registration trials in all age groups in Europe have demonstrated that the vaccine was safe and well tolerated and of immunogenicity standards that met the requirements of the European Committee for Medicinal Products for Human Use. There are no published clinical trials evaluating the effectiveness or efficacy of Fluarix against influenza and its complications. Currently, Fluarix plays an important role in the diversification of the supply chain of influenza vaccine to the community. However, vaccines with improved immunogenicity in at-risk populations, such as the elderly, and with less reliance on growth in eggs, as well as the inherent demanding timelines, are needed to enhance the control of influenza.

    In 2010 the identities of thousands of anti-Plasmodium compounds were released publicly to facilitate malaria drug development. Understanding these compounds’ mechanisms of action—i.e., the specific molecular targets by which they kill the parasite—would further facilitate the drug development process. Given that kinases are promising anti-malaria targets, we screened ~14,000 cell-active compounds for activity against five different protein kinases. Collections of cell-active compounds from GlaxoSmithKline (the ~13,000-compound Tres Cantos Antimalarial Set, or TCAMS), St. Jude Children’s Research Hospital (260 compounds), and the Medicines for Malaria Venture (the 400-compound Malaria Box) were screened in biochemical assays of Plasmodium falciparum calcium-dependent protein kinases 1 and 4 (CDPK1 and CDPK4), mitogen-associated protein kinase 2 (MAPK2/MAP2), protein kinase 6 (PK6), and protein kinase 7 (PK7). Novel potent inhibitors (IC50 < 1 μM) were discovered for three of the kinases: CDPK1, CDPK4, and PK6. The PK6 inhibitors are the most potent yet discovered for this enzyme and deserve further scrutiny. Additionally, kinome-wide competition assays revealed a compound that inhibits CDPK4 with few effects on ~150 human kinases, and several related compounds that inhibit CDPK1 and CDPK4 yet have limited cytotoxicity to human (HepG2) cells. Our data suggest that inhibiting multiple Plasmodium kinase targets without harming human cells is challenging but feasible. PMID:26934697

    Thrombosis portends a poor prognosis in individuals with solid tumors. Constitutive expression of tissue factor (TF) by cancer cells is a key in triggering activation of coagulation and promoting aggressive tumor behavior. Though multiple myeloma (MM) is associated with a high frequency of thrombosis in the context of thalidomide and lenalidomide therapy, prognosis is not affected by its occurrence. We sought to determine the expression of TF in MM. F3 (TF gene) expression profiling was analyzed in 55 human MM cell lines (HMCL) and in 223 solid tumor cell lines obtained from GlaxoSmithKline (GSK) Cancer Cell Line Genomic Profiling Dataset. TF was not expressed in any of the 55 HMCLs studied, in sharp contrast to solid tumors, 90% of which showed TF expression. F3 expression was also absent in tumor samples from 239 MM patients. Immunohistochemistry for TF was negative, with either no or focal (1+) staining in 70/73 MM patients. Only three marrow biopsies were moderately (2+) positive either focally or diffusely, suggesting that in rare cases bone marrow microenvironment may support TF expression. General lack of TF expression by neoplastic plasma cells may explain why thrombosis is not predictive of poor outcome, and why aspirin prophylaxis is often effective in MM. PMID:22333877

    2013-11-01

    In this paper, we propose new methods for analyzing cases of vaccine adverse events spontaneously reported to a surveillance database. The methods use the self-controlled case series approach, extended in several ways with parametric and nonparametric assumptions to account for the specific features of the data (large amount of underreporting and variation of reporting with time since vaccination). This work was motivated by the documented risk of intussusception after RotaShield vaccination (Wyeth-Lederle Vaccines, Radnor, Pennsylvania) and used worldwide spontaneous reports of intussusception occurring after Rotarix vaccination (GlaxoSmithKline Biologics, Research Triangle Park, North Carolina) collected between January 2004 and February 2010. The estimated risk during the 3- to 7-day period after vaccination was approximately 5 times higher after dose 1 of Rotarix than after dose 2, which is similar to published findings on the same topic. We undertook a large simulation study to evaluate the performance of the method in different scenarios, including its robustness to different sample sizes and time-dependent reporting functions. The bias was generally small, the type I error rate was correctly controlled, and the power to detect a risk ratio of 4 was satisfactory, provided that the sample size was over 100. The proposed methods are an effective way to explore and quantify vaccine safety signals from spontaneous reports. PMID:24013203

    Acute otitis media (AOM), one of the most common childhood diseases, is associated with a substantial medical, social and economic burden. Non-typeable Haemophilus influenzae (NTHi) and Streptococcus pneumoniae are the two main causes of bacterial OM. The 7-valent pneumococcal CRM(197)-conjugate vaccine (7vCRM, Prevnar/Prevenar, Wyeth) demonstrated efficacy against AOM caused by vaccine pneumococcal serotypes. Protection against overall AOM was also observed with an 11-valent pneumococcal protein D-conjugate vaccine (11Pn-PD) in the Pneumococcal Otitis Efficacy Trial (POET). Following POET, an optimized 10-valent pneumococcal non-typeable H. influenzae protein D-conjugate vaccine (PHiD-CV; Synflorix, GlaxoSmithKline Biologicals) was developed. This vaccine includes serotypes 1, 5, and 7F, in addition to those already included in 7vCRM, and was recently licensed in Europe for active immunization against invasive disease and AOM caused by S. pneumoniae in infants and children from 6 weeks up to 2 years of age. The use of protein D as carrier protein permits avoidance of possible interferences known to occur with some conjugate vaccines, and has the added potential benefit of providing protection against NTHi. This review seeks to highlight the recent advances in the field of OM vaccination, with a focus on data regarding the recently licensed PHiD-CV. PMID:19666154

    2012-01-01

    Background Previous studies of psychological treatment in adults with ADHD have not controlled for medication status and include either medicated participants or mixed samples of medicated and unmedicated participants. The objective of this study is to examine whether use of medication improves outcome of therapy. Method This was a secondary analysis comparing 23 participants randomized to CBT and Dextroamphetamine vs. 25 participants randomized to CBT and placebo. Both patients and investigators were blind to treatment assignment. Two co-primary outcomes were used: ADHD symptoms on the ADHD-RS-Inv completed by the investigator and improvement in functioning as reported by the patient on the Sheehan Disability Scale. Results Both groups showed robust improvement in both symptoms and functioning, but the use of medication did not significantly improve outcome over and above use of CBT and placebo. Conclusion This study replicates previous work demonstrating that CBT is an effective treatment for ADHD in adults. Within the limits of this pilot, secondary analysis we were not able to demonstrate that medication significantly augments the outcome of CBT therapy for adults with ADHD. The study was funded by GlaxoSmithKline, Clinical Trials Registry #GSK707. PMID:22480189

    Diseases like rotavirus afflict both upper- and lower-income countries, but most serious illnesses and deaths occur among the latter. It is a vital public health issue that vaccines for these types of global diseases can recover research and development (R&D) costs from high-priced markets quickly so that manufacturers can offer affordable prices to lower-income nations. Cost recovery depends on how high R&D costs are, and this study attempts to replace high, unverified estimates with lower, more verifiable estimates for two new vaccines, RotaTeq (Merck) and Rotarix (GlaxoSmithKline or GSK), based on detailed searches of public information and follow-up interviews with senior informants. We also offer a new perspective on "cost of capital" as a claim for recovery from public bodies. Our estimates suggest that companies can recover all fixed costs quickly from affluent markets and thus can offer these vaccines to lower-income countries at prices they can afford. Better vaccines are a shared project between companies and public health agencies; greater transparency and consistency in reporting of R&D costs is needed so that fair prices can be established.

    This review describes the pharmacologic, pharmacokinetic, and pharmacodynamic properties of albiglutide, as well as its clinical efficacy and safety. Albiglutide is a novel, once-weekly, injectable glucagon-like peptide-1 receptor agonist for the treatment of type 2 diabetes. The European Commission recently granted marketing authorization for the drug in the European Union and on April 15, 2014, the US Food and Drug Administration approved albiglutide (Tanzeum™ [GlaxoSmithKline LLC, Wilmington, DE, USA]) to improve glycemic control in adults with type 2 diabetes. Albiglutide has been studied in Phase I, II, and III clinical trials. In the Phase III clinical trials, known as the Harmony series, weekly dosing of albiglutide demonstrated reductions in fasting plasma glucose, postprandial plasma glucose, and glycated hemoglobin, and was associated with weight loss. In all phases of the clinical trials, albiglutide administered once weekly showed a safety and tolerability profile similar to that of placebo, with mild gastrointestinal-related complaints and injection site erythema being the most commonly encountered adverse effects. Compared with pioglitazone and liraglutide, albiglutide has been shown to be clinically less effective. However, it offers the benefit of weight loss that pioglitazone does not, with fewer gastrointestinal side effects than liraglutide. As guidelines continue to advocate for patient-centered treatment strategies, once-weekly albiglutide will be an important addition to the growing armamentarium of treatment options for adults with type 2 diabetes needing target glycemic control.

    Ezogabine is an antiepileptic medication approved in June 2011 by the US Food and Drug Administration (FDA) as an adjunctive treatment for partial seizures. Minimal drug interactions and a novel mechanism of action made ezogabine an appealing new treatment option. However, adverse effects reported during clinical trials and following drug approval have been alarming. A Risk Evaluation Mitigation Strategy (REMS) program has been established for urinary retention. A safety alert was published in April 2013 warning ezogabine may cause retinal pigment abnormalities and/or blue-gray discoloration, most notably on or near the lips, nail beds, sclera and conjunctiva with long-term use. In October 2013, the FDA announced a formal label change to ezogabine to include a black boxed warning emphasizing the previously reported warnings of eye and skin discoloration and permanent vision changes. Given the unknown nature of the pathophysiology, consequences and potential for reversibility of these effects, GlaxoSmithKline and the FDA have published recommendations for patients currently receiving ezogabine. Further data from published case reports and long-term safety trials in the future may lend additional insight into these concerning effects. PMID:25642319

    In 2005, in accordance with recommendations made by the European Medicines Agency, the Italian Drug Agency ordered withdrawal of the hexavalent Hexavac() vaccine (Sanofi Pasteur MSD) from the market. Concerns had been raised about the low immunogenicity of the hepatitis B virus component of the vaccine, assessed by measurement of serum antibody levels, and its potential consequences on long-term protection against hepatitis B infection. We evaluated memory T cell response to establish whether there are differences in the protective mechanisms among children who had received either Hexavac() or Infanrix-hexa() (GlaxoSmithKline) as their primary vaccination. Immunological memory was determined by measuring the ability of T cells to proliferate and secrete IFN? by ELISA and intracellular cytokines (IFN? and IL-2) when cultured with hepatitis B surface antigen (HBsAg). The different memory subsets of T cells were also measured. The results indicate that, although they generate different serum antibody levels, both vaccines are efficient in generating T recall responses in vitro five years after the primary vaccination. The less immunogenic Hexavac() vaccine induces a strong T antigen response, as indicated by increased blast proliferation and the enhanced presence of memory subsets after HBsAg recall stimulation. These findings suggest that cellular immune response should be considered alongside serological markers as a surrogate of protection. PMID:23174200

    The immunogenicity of a vaccine is conventionally measured through the level of serum Abs early after immunization, but to ensure protection specific Abs should be maintained long after primary vaccination. For hepatitis B, protective levels often decline over time, but breakthrough infections do not seem to occur. The aim of this study was to demonstrate whether, after hepatitis B vaccination, B-cell memory persists even when serum Abs decline. We compared the frequency of anti-hepatitis-specific memory B cells that remain in the blood of 99 children five years after priming with Infanrix -hexa (GlaxoSmithKline) (n=34) or with Hexavac (Sanofi Pasteur MSD) (n=65). These two vaccines differ in their ability to generate protective levels of IgG. Children with serum Abs under the protective level, <10 mIU/mL, received a booster dose of hepatitis B vaccine, and memory B cells and serum Abs were measured 2 wk later. We found that specific memory B cells had a similar frequency in all children independently of primary vaccine. Booster injection resulted in the increase of memory B cell frequencies (from 11.3 in 10(6) cells to 28.2 in 10(6) cells, p<0.01) and serum Abs (geometric mean concentration, GMC from 2.9 to 284 mIU/mL), demonstrating that circulating memory B cells effectively respond to Ag challenge even when specific Abs fall under the protective threshold.

    Combination vaccines that include multiple antigens within one formulation are now widely accepted as an effective means of eliciting protection against several diseases at the same time. Owing to improvements in quality and convenient modes of administration, they have become part of routine pediatric practice. Hexavalent vaccines, including diphtheria, tetanus, pertussis, hepatitis B, polio and Haemophilus influenzae type b antigens represent the latest advance in the development of combination vaccines. Over 8 years since its first licensure, this review looks at the immunogenicity, efficacy and safety profile of the only hexavalent pediatric vaccine currently in use--Infanrix hexa (diphtheria, tetanus, acellular pertusis-hepatitis B virus-inactivated poliovirus vaccine/Haemophilus influenzae type b vaccine [DTPa-HBV-IPV/Hib]; GlaxoSmithKline Biologicals, Rixensart, Belgium)--through published clinical trials and postmarketing surveillance data. These data show DTPa-HBV-IPV/Hib to be highly immunogenic and well tolerated across a range of different primary and booster vaccination schedules, as well as when administered concomitantly with other licensed vaccines (e.g., pneumococcal conjugate vaccine). Additional issues surrounding the use of hexavalent vaccines are also reviewed. PMID:19485747

    Infant vaccination using 2-dose priming at 3 and 5 mo of age with a booster at 11-12 mo of age was pioneered in Italy. The 3-5-11 schedule is now used in a growing number of European countries. Infanrix hexa (DTPa-HBV-IPV/Hib, GlaxoSmithKline Vaccines) was first licensed for use in 2000 and has been the only pediatric hexavalent vaccine available since 2005. We reviewed available clinical trial data describing the immunogenicity of DTPa-HBV-IPV/Hib when administered at 3, 5, and 11 mo of age, and conducted an analysis of safety using global and Italian post-marketing surveillance data. In Italy, DTPa-HBV-IPV/Hib has a demonstrated safety record extending over a decade of use, it has been associated with record levels of vaccine coverage, and with sustained disease control in vaccinated cohorts. Hexavalent vaccines will continue to contribute to high vaccine coverage in Italy and across Europe. PMID:24004825

    A pooled analysis of data from four vaccination studies conducted in Europe was undertaken to assess the immunogenicity of Infanrix hexa (DTPa-HBV-IPV/Hib, GlaxoSmithKline Biologicals) when administered in a total of 702 healthy infants at 3, 5 and 11-12 months of age. One month after dose 2, between 96.3% and 100% of subjects had seroprotective antibodies against diphtheria, tetanus, hepatitis B and poliovirus types 1, 2 and 3; 91.7% against Hib and ?99.0% were seropositive for each pertussis antigen. One month after the third dose, 98.9-100% of subjects were seroprotected/seropositive for all vaccine antigens. Geometric mean antibody concentrations/titres for each vaccine antigen increased by 6.7-52.9 fold after the third vaccine dose. No serious adverse events in DTPa-HBV-IPV/Hib recipients were vaccine related. Infanrix hexa induces an adequate immune response after 2-dose primary plus booster doses when administered according to a 3, 5 and 11 months schedule. PMID:22349525

    The aim of the study was to investigate the bioequivalence of a generic product of 8 mg film-coated tablets (test) to the branded product (reference) at the same strength in order to apply for regulatory approval. The secondary objective of the study was to compare the tolerability of both products. A double blinded, randomized, cross-over, 2-period, comparative study was conducted in healthy Caucasian volunteers under fasting conditions. A single oral dose administration of the test or reference product was followed by a 7-day wash-out period. The ondansetron concentration was determined using a validated high performance liquid chromatography with a UV detection method. The 90% confidence interval of the point estimate (test over reference products) for C(max) and AUC(0-t) fell within the 80.00-125.00% acceptance range. The results of the study indicate that the film-coated tablets of Ondatron 8 mg manufactured by Tarchomińskie Zakłady Farmaceutyczne Polfa S.A. (test product) are bioequivalent to those of Zofran manufactured by GlaxoSmithKline Export Ltd (reference product). Both products were well tolerated. PMID:24132707

    Human papillomavirus (HPV) infection causes virtually all cases of cervical cancer, the second most common cause of death from cancer among women worldwide. This Review examines prophylactic HPV subunit vaccines based on the ability of the viral L1 capsid protein to form virus-like particles (VLPs) that induce high levels of neutralizing antibodies. Following preclinical research by laboratories in the nonprofit sector, Merck and GlaxoSmithKline are developing commercial versions of the vaccine. Both vaccines target HPV16 and HPV18, which account for approximately 70% of cervical cancer. The Merck vaccine also targets HPV6 and HPV11, which account for approximately 90% of external genital warts. The vaccines have an excellent safety profile, are highly immunogenic, and have conferred complete type-specific protection against persistent infection and associated lesions in fully vaccinated women. Unresolved issues include the most critical groups to vaccinate and when the vaccine's cost may be low enough for widespread implementation in the developing world, where 80% of cervical cancer occurs.

    Human papillomavirus (HPV) are responsible of an important morbidity and mortality. HPV is a significant source of morbidity and mortality. HPV is the most common sexually transmitted infection: adolescents are at high-risk for HPV acquisition. Biologic and epidemiologic studies have demonstrated that HPV infection is a necessary but non-sufficient cause of cervical cancer and genital warts. The vast majority of cervical cancers contain high-risk HPV type and approximately 70% contain HPV types 16 or 18. HPV types 6 or 11 are responsible for approximately 90% of genital warts. Thus, a vaccine that could prevent. Prophylactic vaccines based on the use of virus-like particles (VLPs) obtained by auto-assembly of L1 are under clinical trials. Two vaccines are currently evaluated: Cervarix (GlaxoSmithKline Biologics), a bivalent vaccine against HPV 16 and 18, and Gardasil (Merck & Co) a quadrivalent vaccine against HPV 16, 18, 6, and 11. Phase I, II and III studies have demonstrated that both vaccines are well tolerated and provide an excellent immunogenicity. With approximately 5-year follow-up, both vaccines have been effective in preventing persistent infection with targeted HPV types and in preventing cervical intraepithelial lesions. The optimal target for vaccination is probably 12-year-old girls. PMID:17293248

    A “Meeting on Upstream Rotavirus Vaccines and Emerging Vaccine Producers” was held at the World Health Organization in Geneva, Switzerland on March 28–30, 2006. The purpose was to discuss, evaluate, and weigh the importance of additional rotavirus vaccine candidates following the successful international licensure of rotavirus vaccines by two major pharmaceutical companies (GlaxoSmithKline and Merck) that had been in development for many years. Both licensed vaccines are composed of live rotaviruses that are delivered orally as have been all candidate rotavirus vaccines evaluated in humans. Each is built on the experience gained with previous candidates whose development had either been discontinued or, in the case of the previously licensed rhesus rotavirus reassortant vaccine (Rotashield), was withdrawn by its manufacturer after the discovery of a rare association with intussusception. Although which alternative candidate vaccines should be supported for development and where this should be done are controversial topics, there was general agreement expressed at the Geneva meeting that further development of alternative candidates is a high priority. This development will help insure that the most safe, effective and economic vaccines are available to children in Third World nations where the vast majority of the >600,000 deaths due to rotavirus occur each year. This review is intended to provide the history and present status of rotavirus vaccines as well as a perspective on the future development of candidate vaccines as a means of promulgating plans suggested at the Geneva meeting.

    The World Health Organization estimates that rotavirus diarrhea results in approximately half a million deaths and approximately 2.4 million hospitalizations in developing countries each year. Two live oral rotavirus vaccines, RotaTeq® (RV 5; Merck) and Rotarix® (RV 1; GlaxoSmithKline) with good efficacy against severe rotavirus disease and a reassuring safety profile could substantially impact the burden of rotavirus disease. In April 2009, WHO provided a recommendation for global introduction of these vaccines in national immunization programs of developing countries worldwide. In this article, we review published data on previous candidate rotavirus vaccines and vaccines in current use, with emphasis on their performance in developed versus developing countries. In developed countries, both first and second generation rotavirus vaccines have demonstrated high efficacy against severe rotavirus disease (pooled efficacy = 73% and 85%, respectively). In developing countries, small early trials for the first generation vaccines failed to provide protection against rotavirus disease (pooled efficacy = 20%), however, trials of the second generation vaccines yielded substantial improvements in efficacy in developing countries (pooled efficacy of 51%), leading to a global recommendation for rotavirus vaccine introduction by WHO. Future efforts for these vaccines should focus on optimizing the efficacy and delivery of these vaccines in challenging target populations of Asia and Africa with the greatest burden of severe rotavirus disease.

    This letter reports a theory to calculate the growth rate and start current of a Smith-Purcell free-electron laser, which is a promising radiation source in the terahertz domain. A two-dimensional model was used to investigate the interaction between a sheet electron beam and the surface wave above a lamellar grating. After deriving the growth rate from the dispersion equation, the start current was carefully estimated by considering the power flow above the grating. The agreement between the predictions of our theory and the results from the particle-in-cell simulations is acceptable.

    Generation of THz radiation based on the Smith-Purcell effect in graphene is investigated numerically. The specific device geometry considered involves an electrically biased single-layer sheet of graphene deposited on a periodic array of holes in a solid substrate. Rigorous electrodynamic simulations combined with a basic model of charge transport are presented, showing that technologically significant output power levels can be obtained at geometrically tunable THz frequencies. These results suggest that graphene is a uniquely suited materials platform for the demonstration of THz electron-beam radiation mechanisms in compact solid-state systems.

    Kevin Smith's utilitarian argument against homeopathy(1) is flawed because he did not review and refute the relevant basic science literature on ultra-high dilutions. He also failed to appreciate that allopathic medicine is based on a deductive-nomothetic method and that homeopathic medicine is based on an inductive-idiographic method, and thus that the implications for clinical research are very different. His misunderstanding of provings and of the holism of homeopathic medicine also demonstrated his failure to understand the history, philosophy and method of homeopathy. Finally, I questioned the value of introducing ethical judgment into an ongoing scientific debate. PMID:22506685

    James McCune Smith (1813-1865)--first black American to obtain a medical degree, prominent abolitionist and suffragist, compassionate physician, prolific writer, and public intellectual--has been relatively neglected by historians of medicine. No biography of Smith exists to this day, though he has been the subject of several essays. Born, in his own words, "the son of a self-emancipated bond-woman," and denied admission to colleges in the United States, his native land, Smith earned medical, master's, and baccalaureate degrees at Glasgow University in Scotland. On his return to New York City in 1837, Smith became the first black physician to publish articles in US medical journals. Smith was broadly involved in the anti-slavery and suffrage movements, contributing to and editing abolitionist newspapers and serving as an officer of many organizations for the improvement of social conditions in the black community. In his scientific writings Smith debunked the racial theories in Thomas Jefferson's Notes on the State of Virginia, refuted phrenology and homeopathy, and responded with a forceful statistical critique to the racially biased US Census of 1840. Frederick Douglass, Gerrit Smith, and John Brown personally collaborated with James McCune Smith in the fight for black freedom. As the learned physician-scholar of the abolition movement, Smith was instrumental in making the overthrow of slavery credible and successful. Images Figure 1 PMID:12911258

Smith was broadly involved in the anti-slavery and suffrage movements, contributing to and editing abolitionist newspapers and serving as an officer of many organizations for the improvement of social conditions in the black community. In his scientific writings Smith debunked the racial theories in Thomas Jefferson's Notes on the State of Virginia, refuted phrenology and homeopathy, and responded with a forceful statistical critique to the racially biased US Census of 1840. Frederick Douglass, Gerrit Smith, and John Brown personally collaborated with James McCune Smith in the fight for black freedom. As the learned physician-scholar of the abolition movement, Smith was instrumental in making the overthrow of slavery credible and successful. PMID:12911258

    Smith-Magenis syndrome is a multiple congenital anomalies/mental retardation syndrome associated with a heterozygous deletion of chromosome 17p11.2. Seizures have not been formally studied in this population. Our objectives were to estimate the prevalence of seizures and electroencephalographic (EEG) epileptiform abnormalities in patients with Smith-Magenis syndrome with defined chromosomal rearrangements and to describe the spectrum of abnormal EEG patterns. Prolonged video-EEGs were obtained in 60 patients. Eighteen percent of patients reported a seizure history; however, abnormal EEGs were identified in 31 of the 60 subjects and 27 of 31 were epileptiform. Generalized epileptiform patterns were the most common (73%). Most patients with either small or large deletions had an abnormal EEG (83%; 75%) in contrast to those with a common deletion (49%). Our results indicate that epileptiform EEG abnormalities are frequent in patients with Smith-Magenis syndrome. Considering that close to one third of individuals with Smith-Magenis syndrome with epileptiform abnormalities also had a history of clinical seizures, cortical hyperexcitability and epilepsy should be considered an important component of the Smith-Magenis syndrome clinical phenotype.

    As the conventional means of analyzing the similarity between a query sequence and database sequences, the Smith-Waterman algorithm is feasible for a database search owing to its high sensitivity. However, this algorithm is still quite time consuming. CUDA programming can improve computations efficiently by using the computational power of massive computing hardware as graphics processing units (GPUs). This work presents a novel Smith-Waterman algorithm with a frequency-based filtration method on GPUs rather than merely accelerating the comparisons yet expending computational resources to handle such unnecessary comparisons. A user friendly interface is also designed for potential cloud server applications with GPUs. Additionally, two data sets, H1N1 protein sequences (query sequence set) and human protein database (database set), are selected, followed by a comparison of CUDA-SW and CUDA-SW with the filtration method, referred to herein as CUDA-SWf. Experimental results indicate that reducing unnecessary sequence alignments can improve the computational time by up to 41%. Importantly, by using CUDA-SWf as a cloud service, this application can be accessed from any computing environment of a device with an Internet connection without time constraints. PMID:23653898

    Smith-Magenis syndrome (SMS) is a complex genetic disorder characterized by sleep disturbance, multiple developmental anomalies, psychiatric behavior, and obesity. It is caused by a heterozygous 17p11.2 microdeletion containing the retinoic acid-induced 1 (RAI1) gene or mutation within RAI1. Sleep disorder is one of the most penetrant features of SMS. Molecular genetic studies indicate that RAI1 regulates circadian rhythm genes and when haploinsucient, causes a distorted molecular circadian network that may be the cause of the sleep disturbance and the inverted rhythm of melatonin present in most individuals with SMS. RAI1 also regulates genes involved in development, neurobehavior, and lipid metabolism. Sleep debt, daytime melatonin secretion, and environmental stress often contribute to negative behavior in persons with SMS, and food entrained circadian rhythm also influences food intake behavior and humoral signals, which also affect development and neurobehavior. The cross-talk between circadian rhythm, development, metabolism and behaviors affect the multiple phenotypic outcomes in Smith-Magenis syndrome. These findings shed light on possible effective and personalized drug treatments for SMS patients in the future. PMID:26384114

    This site study plan describes the Borehole Search and Characterization field activities to be conducted during the early stages of Site Characterization at the Deaf Smith County site, Texas. The field program has been designed to provide data useful in addressing information/data needs resulting from Federal/State/Local regulatory requirements and repository program requirements. Air and ground surveys, an extensive literature search, and landowner interviews will be conducted to locate wells within and adjacent to the proposed nuclear waste repository site in Deaf Smith County. Initially, the study will center around the planned Exploratory Shaft Facilities location and will expand outward from that location. Findings from this study may lead to preparation of a new site study plan to search suspected borehole locations, and excavate or reenter known boreholes for additional characterization or remedial action. The Salt Repository Project (SRP) Networks specify the schedule under which the program will operate. The Technical Field Services Contractor (TFSC) is responsible for conducting the field program. Data will be handled and reported in accordance with established SRP procedures. A quality assurance program will be utilized to assure that activities affecting quality are performed correctly and that appropriate documentation is maintained. 13 refs., 6 figs., 3 tabs.

    This paper provides a novel hybrid model for solving the multiple pair-wise sequence alignment problem combining message passing interface and CUDA, the parallel computing platform and programming model invented by NVIDIA. The proposed model targets homogeneous cluster nodes equipped with similar Graphical Processing Unit (GPU) cards. The model consists of the Master Node Dispatcher (MND) and the Worker GPU Nodes (WGN). The MND distributes the workload among the cluster working nodes and then aggregates the results. The WGN performs the multiple pair-wise sequence alignments using the Smith-Waterman algorithm. We also propose a modified implementation to the Smith-Waterman algorithm based on computing the alignment matrices row-wise. The experimental results demonstrate a considerable reduction in the running time by increasing the number of the working GPU nodes. The proposed model achieved a performance of about 12 Giga cell updates per second when we tested against the SWISS-PROT protein knowledge base running on four nodes. PMID:26510289

    A procedure is described for constructing a three-dimensional model of fibril-forming human type II collagen based on the "Smith" microfibril model. This model is a complex of five individual collagen triple-helical molecules, and is based on known structural parameters for collagen. Both experimental and theoretical data were used as constraints to guide the modeling. The resulting fibril model for type II collagen is in agreement with both physical and chemical characteristics produced by experimental staining patterns of type II fibrils. Some advantages of the type II model are that the stereochemistry of all the sidechain groups is accounted for, and specific atomic interactions can now be studied. This model is useful for: development of therapeutics for collagen related diseases; development of synthetic collagen tissues; design of chemical reagents (i.e., tanning agents) to treat collagen-related products; and study of the structural and functional aspects of type II collagen. Described is the procedure by which the Smith microfibril of type II collagen was developed using molecular modeling tools, validation of the model by comparison to electron-microscopic images of fibril staining patterns, and some applications of this microfibril model.

    The application of game theory to evolutionary problems is so commonplace today, that few stop to consider how it all began. John Maynard Smith and George R. Price's 1973 Nature article, "The Logic of Animal Conflict," is often referred to as the first description in the literature of the concept of an evolutionary stable strategy (ESS), but what was the "behind the scenes" of the writing of that seminal paper? This article tracks the little known story of the curious American polymath, George Price. As will be shown, it was an earlier paper, the lost "Antlers, Intraspecific Combat, and Altruism," sent by Price to Nature in August 1968 (Unpublished), and refereed by Maynard Smith, which instigated the birth of the first ESS. Recently, the "Antlers" paper has been re-discovered by the author, shedding new light, together with letters and journals from the personal papers of George Price and John Maynard Smith, on their historical paper.

    For sediment particle sizes between 0.50 mm and 16 mm, the Helley-Smith bedload sampler has a near perfect sediment-trapping efficiency. For particles sizes smaller than 0.50 mm, the Helley-Smith sampler has a high bedload sediment-trapping efficiency because part of the sediement retained by the sampler has been transported in suspension and it cannot be quantified separately from the bedload. For particle sizes larger than about 16 mm, the Helley-Smith sampler has low sediment-trapping efficiency but this may be related to the paucity of coarse particles in transport in the calibration tests rather than reflecting an actual low trap efficiency for large-size particles.

    Previous researchers have developed correlations between oxide electronegativity and oxide basicity. The present paper revises those correlations using a newer method of calculating electronegativity of the oxygen anion. Basicity is expressed using the Smith {alpha} parameter scale. A linear relation was found between the oxide electronegativity and the Smith {alpha} parameter, with an R{sup 2} of 0.92. An example application of this new correlation to the durability of high-level nuclear waste glass is demonstrated. The durability of waste glass was found to be directly proportional to the quantity and basicity of the oxides of tetrahedrally coordinated network forming ions.

    A sample of 315 children aged between 6 and 9 years participated in a 5-month longitudinal study aimed at investigating constraints on representational flexibility as observed in drawing behaviour. The study specifically looked at how external interventions affected children's representations over time. The intervention involved showing children various examples of pretend people in relation to Karmiloff-Smith's (1990) task of requesting children to operate on their normal person drawing procedures. The study confirmed that knowledge introduced exogenously was only beneficial immediately after the intervention. Over time, in contrast to the older children, the younger children reverted to their internal representations that were specified as sequentially fixed lists. The intervention did not promote transfer of learning to the analogous task of drawing pretend houses. The study suggests that exogenous provocations of behaviour are driven by adjunctions, and that reiterated cycles of representational redescription must occur before the externally mediated knowledge becomes flexibly manipulable.

    The rapid developments in the field of laser-driven particle acceleration hold the prospect of intense, highly relativistic electron bunches that are only a few fs long. The determination of the temporal profile of such bunches presents new challenges. The use of a radiative process such as Smith-Purcell radiation (SPR), is particularly promising in this respect. In this technique the beam is made to radiate a small amount of e/m radiation and the temporal profile is reconstructed from the measured spectral distribution of the radiation. We summarise the advantages of SPR and present the design parameters and preliminary results of the experiments at the FACET facility at SLAC. We also discuss a new approach to the problem of the recovery of the 'missing phase', which is essential for the accurate reconstruction of the temporal bunch profile.

    Social excesses, characterised by heightened social motivation, are important for describing social functioning. Smith-Magenis syndrome (SMS) is a potential exemplar of a disorder where heightened social motivation is associated with negative behavioural outcomes. In Down syndrome (DS) strong social motivation is described, but less commonly associated with behavioural problems. Children with SMS (n = 21) and DS (n = 19) were observed during social situations, in which familiarity of adults present and level of attention available were manipulated. Motivation in SMS was characterised by comparatively frequent social initiations when adult attention was low, and stronger preference for familiar adults, compared to DS. Findings provide insight into the nature of social motivation in SMS and support an argument for nuanced consideration of motivation. PMID:26983920

    An inversion procedure is applied to time-dependent velocity and surface elevation data from several West Antarctic glaciers (Smith, Pope and Kohler) in order to reproduce recent behaviour, using basal and horizontal boundary conditions as controls. The inversion provides a good fit to the data, additionally agreeing well with recent observations of grounding line retreat in the region. It cannot be determined from the data, however, whether the control parameters varied meaningfully in time over the period sampled. Having successfully calibrated the model to a decade of observations, the model is then run forward in time several decades, and adjoint sensitivities of grounded mass loss to the unknown parameters are calculated. Continued mass loss from the region is observed in the model: calculated parameters suggest that this loss might not be "within the noise"; however, more sophisticated techniques (e.g. Hessian-based methods) are necessary to quantify its uncertainty.

    Neo-classical economic theory is based on the postulated, nonempiric notion of utility. Neo-classical economists assume that prices, dynamics, and market equilibria are supposed to be derived from utility. The results are supposed to represent mathematically the stabilizing action of Adam Smith's invisible hand. In deterministic excess demand dynamics, however, a utility function generally does not exist mathematically due to nonintegrability. Price as a function of demand does not exist and all equilibria are unstable. Qualitatively, and empirically, the neo-classical prediction of price as a function of demand describes neither consumer nor trader demand. We also discuss five inconsistent definitions of equilibrium used in economics and finance, only one of which is correct, and then explain the fallacy in the economists’ notion of ‘temporary price equilibria’.

    The performance of pyrometallurgical slag cleaning furnaces at many primary copper smelters is dependent in part on the quality of the converter slag, commonly produced in the batch-wise Peirce Smith converter (PSC). In order to understand the impact of converter slag chemistry and at the same time help optimize the converter operation, thermodynamic modeling of molten slag (including any contained slag solid fractions) was carried out on slag produced at the Chagres smelter in Chile. Phase characterization studies on actual plant slag samples were also carried out. The results are provided in the present paper. This work is also considered as a case study example to illustrate the type of work that can be performed to fairly quickly diagnose the quality of converter slag and assess the overall condition of the converter operation.

    Smith-Magenis syndrome (SMS) is a clinically recognizable contiguous gene syndrome, caused by interstitial deletion of chromosome 17p11.2. The SMS phenotype include distinctive facial features, developmental delay and neurobehavioral abnormalities. The patients present major sleep disturbances ascribed to a phase shift of their circadian rhythm of melatonin with a paradoxical diurnal secretion of the hormone. Treatment with morning beta-blockers and evening melatonin reinstated a normally timed melatonin circadian rhythm, improved daytime behavior and restored normal sleep habits, resulting in a greatly improved quality of life for both SMS patients and their family. SMS is the demonstration of biological basis for sleep disorder in a genetic disease. Considering that clock genes mediate generation of circadian rhythms, we suggest that haploinsufficiency for a circadian system gene mapping to chromosome 17p11.2 may cause the inversion of circadian rhythm in SMS.

    A dielectric loaded rectangular grating for Smith-Purcell devices is proposed in this paper. Regarding the electron beam as a moving plasma dielectric, a three dimensional (3D) linear theory of beam-wave interaction is developed. The first and second order growth rates are calculated, which are obtained by expanding hot dispersion equation at synchronous point. The results show that the cutoff frequency is affected by grating width. The dispersion curve becomes flatter and shifts towards lower frequency by loading dielectric in grooves. The simulation results, which are obtained by a 3D particle-in-cell code, are in good agreement with theoretical calculations. Compared the first and second order growth rate, it shows that the discrepancy is large when beam parameters are selected with high values. In this case, it is necessary to apply the second order growth rate, which can accurately describe the process of beam-wave interaction.

    Zingiber zerumbet Smith is an important herb that contains bioactive phytomedicinal compound, zerumbone. To enhance cell growth and production of this useful compound, we investigated the growth conditions of cell suspension culture. Embryogenic callus generated from shoot bud was used to initiate cell suspension culture. The highest specific growth rate of cells was recorded when it was cultured in liquid Murashige and Skoog basal medium containing 3% sucrose with pH 5.7 and incubated under continuous shaking condition of 70 rpm for 16 h light and 8 h dark cycle at 24°C. Our results also revealed that the type of carbohydrate substrate, light regime, agitation speed, and incubation temperature could affect the production of zerumbone. Although the zerumbone produced in this study was not abundant compared to rhizome of Z. zerumbet, the possibility of producing zerumbone during early stage could serve as a model for subsequent improvement.

    Good control of processes with long dead time is often achieved using a Smith predictor configuration. Typically a PI or PID controller is used; however, it is shown in this paper that for some situations improved set point and disturbance responses can be obtained if a PI-PD controller is used. Several methods are possible for selecting the parameters of the PI-PD controller but when the plant transfer function has no zeros, the use of the standard forms provides a simple algebraic approach, and also reveals why difficulties may be encountered if a PID controller is used. Some examples are given to show the value of the approach presented. PMID:12546472

    The area of the Swisher and Deaf Smith County locations is characterized by vast open spaces with limited vertical relief and vegetative cover. The stream valleys and areas around the playa lakes provide the only significant topographical relief in either location, and the areas in range vegetation provide the only major contrast to the dominant land cover of agricultural crops. Tree stands occur almost exclusively in association with orchards, country clubs, farmsteads, and urban areas. Because of climatic conditions in the region, there are few permanent water bodies in either location. Grain elevators, farmsteads, and other cultural modifications (roads, utility lines, fence rows, etc.) are scattered throughout both locations, but they constitute a very small portion of the visible landscape. These features help provide scale in the landscape and also serve as visual landmarks.

They are protected by both federal and state legislation. In the area covered by the Deaf Smith and Swisher County locations, four stages of cultural development have been identified: Paleo-Indian, Archaic, Ceramic (Neo-Indian or Neo-American), and Historic. Areas where undiscovered cultural resources are most likely to be found include sources of water, playa lakes, and historic trails. Because extensive surveying has not been done in either location, the number of identified sites is low.

Then, a comparative evaluation is presented in which estimated impacts based upon the revised data and methods are compared with the impacts published in the EA. The evaluation indicates that the conclusions of the EA air quality and noise impacts sections would be unchanged. Consequently, the guideline findings presented in Chapter 6 of the EA are also unchanged by the revised analysis. 13 tabs.

The mission, to service the Hubble Space Telescope, is scheduled to lift off at 7:50 p.m. EST Dec. 19 on mission STS-103, servicing the Hubble Space Telescope. Objectives for the nearly eight-day mission include replacing gyroscopes and an old computer, installing another solid state recorder, and replacing damaged insulation in the telescope. Discovery is expected to land at KSC Monday, Dec. 27, at about 5:24 p.m. EST.

  13. Observation of Eisenbud–Wigner–Smith states as principal modes in multimode fibre

    Generally, light becomes scattered in space and time as it is coupled among multiple spatial paths during propagation through disordered media or multimode waveguides. This limits the pulse duration and spatial coherence that can be obtained after light exits such a medium. Eisenbud–Wigner–Smith eigenstates, originally proposed in nuclear scattering, are a unique set of input/output states that, despite spatiotemporal scattering during propagation, arrive at the output temporally unscattered. In fibre optics, these states manifest as principal modes that allow pulses and spatial coherence to be maintained despite propagation through a medium that would otherwise have destroyed these properties. These states generalize the phenomena of orthogonal fast/slow axes in a birefringent object to a basis with N axes, where N is the total number of spatial/polarization modes in the scattering medium. We experimentally demonstrate the existence of principal modes using a 100 m length of multimode fibre as the propagation medium.

    The Smith Kettlewell Eye Research Institute (SKERI), celebrating its 50th anniversary in 2014, hosted a symposium to identify the most pressing clinical problems in strabismus and binocular vision. Forty-five experts from around the world shared their perspectives at the San Francisco meeting, held November 6-9, 2012. Prior to the meeting, the organizers (TR, APW, RH, JB, AJ) asked attendees to identify the most pressing clinical problems in strabismus and to discuss them in a workshop-based format. The clinical problems were organized into the following six areas: (1) esotropias; (2) binocular vision: amblyopia, suppression, and diplopia; (3) intermittent exotropia; (4) "oblique dysfunctions"; (5) dissociated vertical deviation (DVD); and (6) new approaches to strabismus management. Herein we highlight of some of the clinical problems discussed at the meeting. PMID:25173911

    The α-humulene synthase from Zingiber zerumbet Smith was expressed as a polyhistidine-tagged protein in an E. coli BL21(DE3) strain. Induction time and inductor (isopropyl-β-D-thiogalactopyranoside) concentration were optimized. The enzyme was successfully purified directly from cell lysate by NTA affinity column chromatography and careful selection of coordinated metal ion and imidazole elution conditions. Bioactivity assays were conducted with the natural substrate farnesyl diphosphate (FDP) in a two-phase system with in situ extraction of products. The conversion of FDP to α-humulene (~94.5 %) and β-caryophyllene (~5.5 %) could be monitored by gas chromatography-flame ionization detection (GC-FID). Optimal pH and temperature as well as kinetic parameters K M and k cat were determined using a discontinuous kinetic assay. PMID:26463657

    Zingiber zerumbet Smith is an important herb that contains bioactive phytomedicinal compound, zerumbone. To enhance cell growth and production of this useful compound, we investigated the growth conditions of cell suspension culture. Embryogenic callus generated from shoot bud was used to initiate cell suspension culture. The highest specific growth rate of cells was recorded when it was cultured in liquid Murashige and Skoog basal medium containing 3% sucrose with pH 5.7 and incubated under continuous shaking condition of 70 rpm for 16 h light and 8 h dark cycle at 24°C. Our results also revealed that the type of carbohydrate substrate, light regime, agitation speed, and incubation temperature could affect the production of zerumbone. Although the zerumbone produced in this study was not abundant compared to rhizome of Z. zerumbet, the possibility of producing zerumbone during early stage could serve as a model for subsequent improvement.

  17. Responding to the second ghetto: Chicago's Joe Smith and Sin Corner.

    Pacyga, Dominic A

    2011-01-01

    World War Two and its aftermath transformed Chicago's African American community. The Great Migration entered a second and more intense phase as black migrants flooded into Northern cities. This massive relocation of Southern blacks resulted in the expansion and reformulation of Chicago's ghettoes on both the West and South Sides of the city. The question of a response to this Second Ghetto from African Americans themselves presents itself. White politicians, cultural elites and businessmen still controlled the city and could impose their will on its neighborhoods simply redrawing ghetto boundaries to reflect the new realities of the postwar era. The strange case of Joe Smith and Sin Corner sheds some light on black agency in the 1950s. The African American middle class had resources it commanded to try and protect itself from racial injustice. These resources, however, were based on class privileges not enjoyed by most in the African American community. PMID:21158199

  4. Final Report - Conservation & Renewable Energy Potential Study For Smith River Rancheria

    SciTech Connect

    Greg Retzlaff

    2007-07-01

    In January 2006 the Smith River Rancheria (SRR), located in Smith River, California, contracted with the team of Strategic Energy Solutions (SES) and Evergreen NRG to conduct a study for the community. The objective of the study was to identify renewable generation opportunities that would facilitate Rancheria energy independence through SRR owned and operated power projects. These generation facilities were to be located either on or near the reservation. Specifically, the Rancheria was interested in the viability of generating electric power using biomass and wind fuel resources. Initial research identified that a very small portion of the community's energy could be offset by renewable energy generation due to the low solar resource in this area, and the lack of significant wind or biomass resources on or near reservation land. Some larger projects were identified which offered little or no benefit to the Rancheria. As a result, the scope of this study was changed in October 2006 to focus on energy efficiency opportunities for key reservation facilities, with a continued analysis of smaller renewable energy opportunities within reservation boundaries. The consulting team initially performed a resource analysis for biomass and solar generation opportunities in the region of the Rancheria. It was quickly concluded that none of these options would yield renewable power for the Rancheria at costs competitive with current utility sources, and that any larger installations would require substantial funding that may not be available. Having made these conclusions early on, the study effort was redirected and the team investigated each of the major Rancheria buildings to look for solar, wind and conservation opportunities. The buildings were audited for energy use and the roof areas were examined for exposure of solar radiation. Wind resources were also investigated to determine if smaller wind turbines would offer power generation at a reasonable cost.

    The colubrid snake Chrysopelea taprobanica Smith, 1943 was described from a holotype from Kanthali (= Kantalai) and paratypes from Kurunegala, both localities in Sri Lanka (formerly Ceylon) (Smith 1943). Since its description, literature pertaining to Sri Lankan snake fauna considered this taxon to be endemic to the island (Taylor 1950, Deraniyagala 1955, de Silva 1980, de Silva 1990, Somaweera 2004, Somaweera 2006, de Silva 2009, Pyron et al. 2013). In addition, earlier efforts on the Indian peninsula (e.g. Das 1994, 1997, Das 2003, Whitaker & Captain 2004, Aengals et al. 2012) and global data compilations (e.g. Wallach et al. 2014, Uetz & Hošek 2015) did not identify any record from mainland India until Guptha et al. (2015) recorded a specimen (voucher BLT 076 housed at Bio-Lab of Seshachalam Hills, Tirupathi, India) in the dry deciduous forest of Chamala, Seshachalam Biosphere Reserve in Andhra Pradesh, India in November 2013. Guptha et al. (2015) further mentioned an individual previously photographed in 2000 at Rishi Valley, Andhra Pradesh, but with no voucher specimen collected. Guptha's record, assumed to be the first confirmed record of C. taprobanica in India, is noteworthy as it results in a large range extension, from northern Sri Lanka to eastern India with an Euclidean distance of over 400 km, as well as a change of status, i.e., species not endemic to Sri Lanka. However, at least three little-known previous records of this species from India evaded most literature and were overlooked by the researchers including ourselves. PMID:25947759

    2010-01-01

    Smith-Magenis syndrome (SMS) is a complex syndrome involving intellectual disabilities, sleep disturbance, behavioural problems, and a variety of craniofacial, skeletal, and visceral anomalies. While the majority of SMS cases harbor an ~3.5 Mb common deletion on 17p11.2 that encompasses the retinoic acid induced-1 (RAI1) gene, some patients carry small intragenic deletions or point mutations in RAI1. We present data on two cases of Smith-Magenis syndrome with mutation of RAI1. Both cases are phenotypically consistent with SMS and RAI1 mutation but also have other anomalies not previously reported in SMS, including spontaneous pneumothoraces. These cases also illustrate variability in the SMS phenotype not previously shown for RAI1 mutation cases, including hearing loss, absence of self-abusive behaviours, and mild global delays. Sequencing of RAI1 revealed mutation of the same heptameric C-tract (CCCCCCC) in exon 3 in both cases (c.3103delC one case and and c.3103insC in the other), resulting in frameshift mutations. Of the seven reported frameshift mutations occurring in poly C-tracts in RAI1, four cases (~57%) occur at this heptameric C-tract. Collectively, these results indicate that this heptameric C-tract is a preferential hotspot for single nucleotide insertion/deletions (SNindels) and therefore, should be considered a primary target for analysis in patients suspected for mutations in RAI1. We expect that as more patients are sequenced for mutations in RAI1, the incidence of frameshift mutations in this hotspot will become more evident. PMID:20932317

    Cultural resources at the Deaf Smith County site will be identified, evaluated and managed through the implementation of studies detailed in the Site Study Plan for Cultural Resources. This technical procedure outlines the conduct of pedestrian survey and the documentation of identified cultural resources. The purpose of the field surveys is to identify and document cultural resources in the areas that will be affected by site characterization activities and to record the environmental setting of identified cultural resources. Three pedestrian surveys will cover 100 percent of the on-site and off-site project areas. Survey 1 will provide coverage of the Repository Surface Facility (RSF) area, which includes the Exploratory Shaft Facility (ESF) and two linear engineering design borehole (EDBH) seismic survey corridors. Survey 2 will provide coverage of a 39 km/sup 2/ (15 mi/sup 2/) area that includes the 23 km/sup 2/ (9 mi/sup 2/) Deaf Smith County site plus a 0.4 to 0.8 kM (1/4 to 1/2 mi) border area but excludes the area covered by Survey 1. Survey 3 will cover offsite geotechnical test areas, such as the locations of playa boreholes, deep playa wells, hydrologic tests, site foundation borings, and their access routes. The purpose of site documentation or recording is to address the project information needs for land use permits and approvals, engineering design support, and cultural resource evaluation for National Register of Historic Places eligibility. Site documentation will consist of gathering sufficient data on identified resources to complete Texas Natural Resource Information System (TNRIS). 7 refs., 3 figs.

  8. Adaptive Smith-Waterman residue match seeding for protein structural alignment.

    2013-10-01

    The POLYFIT rigid-body algorithm for automated global pairwise and multiple protein structural alignment is presented. Smith-Waterman local alignment is used to establish a set of seed equivalences that are extended using Needleman-Wunsch dynamic programming techniques. Structural and functional interaction constraints provided by evolution are encoded as one-dimensional residue physical environment strings for alignment of highly structurally overlapped protein pairs. Local structure alignment of more distantly related pairs is carried out using rigid-body conformational matching of 15-residue fragments, with allowance made for less stringent conformational matching of metal-ion and small molecule ligand-contact, disulphide bridge, and cis-peptide correspondences. Protein structural plasticity is accommodated through the stepped adjustment of a single empirical distance parameter value in the calculation of the Smith-Waterman dynamic programming matrix. Structural overlap is used both as a measure of similarity and to assess alignment quality. Pairwise alignment accuracy has been benchmarked against that of 10 widely used aligners on the Sippl and Wiederstein set of difficult pairwise structure alignment problems, and more extensively against that of Matt, SALIGN, and MUSTANG in pairwise and multiple structural alignments of protein domains with low shared sequence identity in the SCOP-ASTRAL 40% compendium. The results demonstrate the advantages of POLYFIT over other aligners in the efficient and robust identification of matching seed residue positions in distantly related protein targets and in the generation of longer structurally overlapped alignment lengths. Superposition-based application areas include comparative modeling and protein and ligand design. POLYFIT is available on the Web server at http://polyfit.insa-toulouse.fr. PMID:23720362

    Smith-Magenis syndrome (SMS) is a sporadic congenital disorder involving multiple organ systems caused by chromosome 17p11.2 deletions. Smith-Magenis syndrome features craniofacial and skeletal anomalies, cognitive impairment, and neurobehavioral abnormalities. In addition, some SMS patients may exhibit hypogammaglobulinemia. We report the first case of SMS-associated autoimmunity in a woman who presented with adult onset of multiple autoimmune disorders, including systemic lupus erythematosus, antiphospholipid antibody syndrome, and autoimmune hepatitis. Molecular analysis using single-nucleotide polymorphism array confirmed a de novo 3.8-Mb deletion (breakpoints, chr17: 16,660,721–20,417,975), resulting in haploinsufficiency for TACI (transmembrane activator and CAML interactor). Our data are consistent with potential loss of function for the BAFF (B cell–activating factor) receptor TACI as a contributing factor to human autoimmune phenomena. PMID:25036569

    A modification of Smith predictor for controlling the higher order processes with integral action ad long dead-time is proposed in this paper. The controller used in this Smith predictor is an Integral-Proportional Derivative controller, where the Integrator is in the forward path and the Proportional and Derivative control are in the feedback, acting on the feedback signal. The main objective of this paper is to design a Dead Time Compensator(DTC), which has minimum tuning parameters, simple controller tuning, robust performance of tuning formulae and to obtain a critically damped system which is as fast as possible in its setpoint and load disturbance rejection performance. The controller in this paper is tuned by an adaptive method. This paper also presents a survey of various dead time compensators and their performance analysis.

    We appreciate the thoughtful comments on Marin and Miller (2013). Both commentaries questioned the validity of our conclusions about interpersonal sensitivity (IS) and health, with Smith (2013) arguing that we overstated the conclusions and Denollet (2013) arguing that we did not take them far enough. Here we offer a middle-ground approach to interpreting the IS-health literature. We discuss our rationale for including introversion as an IS construct, and we point readers to high-quality evidence that specifically rules out some of the competing explanations raised by Smith (2013). Finally, we argue that additional work in this area is needed before specific hypotheses about biological mechanisms and the roles of age and disease stage as possible moderators can be tested.

    Smith-Lemli-Opitz syndrome (SLOS) is a common autosomal-recessive disorder that results from mutations in the gene encoding the cholesterol biosynthetic enzyme 7-dehydrocholesterol reductase (DHCR7). Impaired DHCR7 function is associated with a spectrum of congenital malformations, intellectual impairment, epileptiform activity and autism spectrum disorder. Biochemically, there is a deficit in cholesterol and an accumulation of its metabolic precursor 7-dehydrocholesterol (7DHC) in developing tissues. Morphological abnormalities in SLOS resemble those seen in congenital Sonic Hedgehog (SHH)-deficient conditions, leading to the proposal that the pathogenesis of SLOS is mediated by aberrant SHH signalling. SHH signalling is transduced through the transmembrane protein Smoothened (SMO), which localizes to the primary cilium of a cell on activation and is both positively and negatively regulated by sterol molecules derived from cholesterol biosynthesis. One proposed mechanism of SLOS involves SMO dysregulation by altered sterol levels, but the salient sterol species has not been identified. Here, we clarify the relationship between disrupted cholesterol metabolism and reduced SHH signalling in SLOS by modelling the disorder in vitro. Our results indicate that a deficit in cholesterol, as opposed to an accumulation of 7DHC, impairs SMO activation and its localization to the primary cilium. PMID:26685159

    Smith-Lemli-Opitz syndrome (SLOS) is a multiple congenital anomaly/mental retardation syndrome, with features including toe syndactyly, genital anomalies, unusual facies, and occasional organ malformations. The gene(s) for this autosomal recessive disorder has not been mapped. Recent biochemical studies suggest that the defect may involve the penultimate step in cholesterol synthesis, as patients have low serum cholesterol and increased 7-dehydrocholesterol (7-DHC) levels. However, the enzyme putatively involved (7-DHC reductase) has not been isolated. We identified an SLOS patient with a de novo balanced chromosome translocation [t(7;20)(q32.1;q13.2)], and we propose that the translocation interrupts one of the patient`s SLOS alleles. We are pursuing positional cloning to identify the SLOS gene. Using fluorescence in situ hybridization (FISH), we recently identified a chromosome 7 yeast artificial chromosome (YAC) that spans the breakpoint and places it onto physical and genetic maps. We are in the process of narrowing this region via overlapping YACs and YAC subclones, from which we will isolate candidate cDNAs. Any candidate gene disrupted by the translocation and mutated on the other allele will be proven to be the SLOS gene. Functional analysis of an SLOS cDNA may also determine its relationship to cholesterol metabolism and the observed biochemical abnormalities.

    Smith-Lemli-Opitz (SLO) syndrome is an autosomal recessive disorder characterized by multiple congenital abnormalities and mental retardation. The condition is caused by the deficiency of 7-dehydrocholesterol reductase (DHCR7) which catalyzes the final step in cholesterol biosynthesis. Biochemical diagnosis is based on increased concentration of 7-dehydrocholesterol (7-DHC) in the patient serum. Both life expectancy and quality of life are severely affected by the disease. The estimated prevalence of SLO syndrome ranges between 1:20,000 and 1:40,000 among Caucasians. Although the mutational spectrum of the disease is wide, approximately 10 mutations are responsible for more than 80% of the cases. These mutations show a large interethnic variability. There are no mutation distribution data from Hungary to date. Thirteen patients were diagnosed with SLO syndrome in our laboratory. As first-line tests, serum 7-DHC and total cholesterol were measured and, in positive cases, molecular genetic analysis of the DHCR7 gene was performed. Complete genetic background of the disease could be identified in 12 cases. In 1 case only 1 mutation was detected in a heterozygote form. One patient was homozygous for the common splice site mutation c.964–1G>C, while all other patients were compound heterozygotes. One novel missense mutation, c.374A>G (p.Tyr125Cys) was identified.

    A drifting electron laser (DEL) [S. Riyopoulos, Phys. Plasmas 3, 3828 (1996)] can by far exceed the 1/2Nw free electron laser (FEL) efficiency limit, provided the radiation strength exceeds that of the wiggler. It is shown here that a Smith-Purcel DEL, powered by an E×B drifting electron beam grazing a corrugated structure (grating), achieves high efficiency through unbound electron excursions at much lower radiation power; the radiation strength must only exceed the small strength of the dc potential ripple caused by the corrugation. Efficiency reduction, caused in a wiggler based DEL by a Gaussian radiation beam of small spot size, is also avoided. The nonlinear saturation efficiency of the grating DEL is obtained analytically for a sheet beam. The effects of the drift velocity shear caused by the space-charge field, as well as that of the thermal spreads in the injection velocity are found to be small and easier to overcome than in a FEL. It is also proven that, even for operation at low power, the efficiency remains higher than in a grating FEL due to comparatively larger height of the trapped particle island.

    Smith-Lemli-Opitz syndrome (SLOS) is a congenital, autosomal recessive metabolic and developmental disorder caused by mutations in the enzyme which catalyzes the reduction of 7-dehydrocholesterol (7DHC) to cholesterol. Herein we show that dermal fibroblasts obtained from SLOS children display increased basal levels of LC3B-II, the hallmark protein signifying increased autophagy. The elevated LC3B-II is accompanied by increased beclin-1 and cellular autophagosome content. We also show that the LC3B-II concentration in SLOS cells is directly proportional to the cellular concentration of 7DHC, suggesting that the increased autophagy is caused by 7DHC accumulation secondary to defective DHCR7. Further, the increased basal LC3B-II levels were decreased significantly by pretreating the cells with antioxidants implicating a role for oxidative stress in elevating autophagy in SLOS cells. Considering the possible source of oxidative stress, we examined mitochondrial function in the SLOS cells using JC-1 assay and found significant mitochondrial dysfunction compared to mitochondria in control cells. In addition, the levels of PINK1 which targets dysfunctional mitochondria for removal by the autophagic pathway are elevated in SLOS cells, consistent with mitochondrial dysfunction as a stimulant of mitophagy in SLOS. This suggests the increase in autophagic activity may be protective, i.e., to remove dysfunctional mitochondria. Taken together, these studies are consistent with a role for mitochondrial dysfunction leading to increased autophagy in SLOS pathophysiology. PMID:25405082

    Here we present a 24-week fetus with Smith-Lemli-Opitz syndrome (SLOS), alobar holoprosencephaly (HPE) and cyclopia (synophthalmia). Following birth, we suspected SLOS in this fetus due to the additional findings of ambiguous genitalia and bilateral 2–3 toe syndactyly. The diagnosis of SLOS was confirmed by finding an elevated amniotic fluid 7-dehydrocholesterol level (9890 ng/mL; normal range = 3–9 ng/mL), and molecularly by detecting two different mutations in the DHCR7 gene, the gene causing SLOS. The first mutation was an IVS8-1G>T change and the second was a deletion of exons 3 and 4; this latter mutation has not been reported previously. The mother carries the deletion, while the father carries the splice-site mutation. Also of note, the father has an abnormally low total plasma cholesterol level (104–109 mg/dL). This is the most severe case of HPE described in any patient with SLOS. We postulate that the HPE in this case resulted from severe impairment of Sonic Hedgehog signaling secondary to abnormal cholesterol metabolism; however, the unique combination of mutations in the fetus functionally appears to be no different from other homozygous null mutations reported in DHCR7. Therefore, there must be other yet to be identified factors that contributed to the severity of HPE in SLOS. PMID:20104611
