  8. On call at the mall: a mixed methods study of U.S. medical malls

    PubMed Central

    2013-01-01

    Background The decline of the traditional U.S. shopping mall and a focus on more consumer- centered care have created an opportunity for “medical malls”. Medical malls are defined as former retail spaces repurposed for healthcare tenants or mixed-use medical/retail facilities. We aimed to describe the current reach of healthcare services in U.S. malls, characterize the medical mall model and emerging trends, and assess the potential of these facilities to serve low-income populations. Methods We used a mixed methods approach which included a comprehensive literature review, key informant interviews, and a descriptive analysis of the Directory of Major Malls, an online retail database. Results Six percent (n = 89) of large, enclosed shopping malls in the U.S. include at least one non-optometry or dental healthcare tenant. We identified a total of 28 medical malls across the U.S., the majority of which opened in the past five years and serve middle or high income populations. Stakeholders felt the key strengths of medical malls were more convenient access including public transportation, greater familiarity for patients, and “one stop shopping” for primary care and specialty services as well as retail needs. Conclusions While medical malls currently account for a small fraction of malls in the US, they are a new model for healthcare with significant potential for growth. PMID:24209495

    The aim of the present study was to determine whether MALL expression is associated with colon cancer progression and patient survival. MALL mRNA expression was reduced in the tumor tissues of 70% of the colon cancer patients and 75% of the rectal cancer patients as compared to their normal tissues. MALL protein was also significantly reduced in the tumor tissues of colon cancer patients (P < 0.001). Increased LOH and methylation of MALL was observed in tumor tissues as compared to normal tissues. Reduced MALL expression was associated with vessin invasion, disease recurrence and metastasis or death (P ≤ 0.027). Furthermore, patients with MALL-negative tumors had significantly decreased overall survival (OS) and disease-free survival (DFS) (P < 0.008 and P < 0.011, respectively). Univariate analysis indicated that MALL expression was significantly associated with OS and DFS. Finally, overexpression of MALL suppressed HCT116 and SW480 cell proliferation and inhibited HCT116 migration. MALL may play a role in colorectal cancer progression as suppression of its expression in tumor tissues negatively impacts colorectal cancer patient survival. Further analyses are required to determine if reduced MALL expression is due to LOH and/or methylation. PMID:26992238

    Introduction Walking is a preferred and recommended physical activity for middle-aged and older adults, but many barriers exist, including concerns about safety (ie, personal security), falling, and inclement weather. Mall walking programs may overcome these barriers. The purpose of this study was to summarize the evidence on the health-related value of mall walking and mall walking programs. Methods We conducted a scoping review of the literature to determine the features, environments, and benefits of mall walking programs using the RE-AIM framework (reach, effectiveness, adoption, implementation, and maintenance). The inclusion criteria were articles that involved adults aged 45 years or older who walked in indoor or outdoor shopping malls. Exclusion criteria were articles that used malls as laboratory settings or focused on the mechanics of walking. We included published research studies, dissertations, theses, conference abstracts, syntheses, nonresearch articles, theoretical papers, editorials, reports, policy briefs, standards and guidelines, and nonresearch conference abstracts and proposals. Websites and articles written in a language other than English were excluded. Results We located 254 articles on mall walking; 32 articles met our inclusion criteria. We found that malls provided safe, accessible, and affordable exercise environments for middle-aged and older adults. Programmatic features such as program leaders, blood pressure checks, and warm-up exercises facilitated participation. Individual benefits of mall walking programs included improvements in physical, social, and emotional well-being. Limited transportation to the mall was a barrier to participation. Conclusion We found the potential for mall walking programs to be implemented in various communities as a health promotion measure. However, the research on mall walking programs is limited and has weak study designs. More rigorous research is needed to define best practices for mall walking

    The annual Astronomy Festival on the National Mall (AFNM) takes place on 11 acres north of the Washington Monument in June (previous AFNM were April and July). AFNM, sponsored by Hofstra University, features optical and radio telescope viewing of the Sun, Moon, planets, stars, clusters, and nebulae; a live large-screen image, a cell phone imaging mount; exhibits; hands-on activities; videos; large outdoor banners and posters; citizen science activities; hand-outs; bookmarks, and teacher information materials. With no tall buildings almost the entire sky is visible and 10th mag. moons of Saturn and the Ring Nebula (9.75 mag.) were easily visible on clear nights. Representatives from some of the nation's foremost scientific and educational institutions presented exciting demonstrations and activities; and answered questions about careers in science, celestial objects, and the latest astronomical discoveries. Local amateur astronomers set up twenty telescopes on the Mall and long lines of 20-30 people waited to look through the telescopes. Visitors met astronaut Dr. John Grunsfeld (Associate Administrator, NASA) and astronomers Dr. Lisse, Dr. Livengood, Dr. Warren, and Dr. Paul Hertz (Director, Astrophysics Division, NASA). Important historical astronomers spoke to the attendees: Caroline Herschel (Lynn King); Tycho Brahe (Dean Howarth); and Johannes Kepler (Jeff Jones). Free telescopes, donated by Celestron, were raffled off.

    2007-12-01

    Astronomy had a visible presence on the Nation's Mall from the 1890s through 1955, when the Smithsonian's Astrophysical Observatory, nestled in a series of low buildings between the Castle and Independence Avenue, was closed, and its programs moved to Harvard. Since that time, save for a singular but failed effort to create a separate national planetarium on the Mall, astronomy has maintained a solid presence through exhibits and displays within the Smithsonian's museums and the National Academy of Sciences, and off the Mall, at the Carnegie Institution, the AAAS, and at both the old and the new U.S. Naval Observatory. Here we will relate how history has played an important role in keeping astronomy visible on the Nation's Mall, and why the interest of the astronomical community is critical to maintaining this visibility.

    1994-09-01

    The MARI spectrometer is funded by the Japanese Ministry of Education, Culture and Science (Monbusho) as part of the UK-Japan collaboration in neutron scattering. MARI is a direct geometry chopper spectrometer. It uses a Fermi chopper to monochromatic the incident neutron beam to give incident energies in the range 10 to 2000 meV. It is very similar in design to its sister machine HET, but with a detector bank that continuously covers the angular range from 3 to 135 degrees, MARI is able to map large regions of Q-E space in a single measurement. At present about 600 of the full complement of 1000 detectors are installed. All are 10 bar (3)He gas proportional counters and all come from the same manufacturer, this means that their efficiency and background are almost the same. The beam size at the sample position is 50 by 50 mm, but motorized jaws in the Fermi chopper pit and in the sample tank can be used to reduce this size. Chapter headings are the following: Introduction; The hardware on MARI; Controlling the Instrument; Data Analysis and Visualization; Appendices.

Psychoanalytic theory suggests dogma arises out of the psychic needs of people and psychic needs of people are expressed in dogma. The early views of Erich Fromm, a disciple of Freud, are presented to demonstrate that Marian dogma arose from the psychic needs of the people. The views of both Catholic and Protestant thinkers are presented, as well as theological and psychiatric views.

    Double sequential defibrillation is currently being employed in a number of EMS systems across the United States, including Wake County, N.C.; Fort Worth, Texas; and New Orleans. Even though there isn't a large body of literature surrounding this technique, it's been demonstrated successful in the electrophysiology lab, ED and prehospital settings. Since access to procainamide--another treatment for refractory v fib--is limited, this may be the only available option when faced with a patient who's failed standard ACLS defibrillation and medication administration. It's an intervention that has little chance to do harm, and it may represent the "hail Mary" pass to a successful ROSC touchdown. PMID:27301098

  17. Mary and femininity: A psychological critique.

    PubMed

    Harrington, P A

    1984-09-01

    This essay uses Freud to interpret the symbolism and theology of Mary in modern Catholicism. In her role as the mother of believers, Mary functions to place the Christian in the position of a child who receives illusory gratification from the mother. In her role as model for Christians to emulate, Mary functions to place the Christian in the position of receptivity and dependence which Freud associated with femininity. Reinterpreting Freud from a feminist perspective, I suggest that the kind of femininity Mary represents serves to perpetuate patriachal social structures and to inhibit full psychological maturity.

    Objectives: To determine the genetic distribution and the phenotypic correlation of an extensive series of patients with Charcot-Marie-Tooth disease in a geographically well-defined Mediterranean area. Methods: A thorough genetic screening, including most of the known genes involved in this disease, was performed and analyzed in this longitudinal descriptive study. Clinical data were analyzed and compared among the genetic subgroups. Results: Molecular diagnosis was accomplished in 365 of 438 patients (83.3%), with a higher success rate in demyelinating forms of the disease. The CMT1A duplication (PMP22 gene) was the most frequent genetic diagnosis (50.4%), followed by mutations in the GJB1 gene (15.3%), and in the GDAP1 gene (11.5%). Mutations in 13 other genes were identified, but were much less frequent. Sixteen novel mutations were detected and characterized phenotypically. Conclusions: The relatively high frequency of GDAP1 mutations, coupled with the scarceness of MFN2 mutations (1.1%) and the high proportion of recessive inheritance (11.6%) in this series exemplify the particularity of the genetic distribution of Charcot-Marie-Tooth disease in this region.

    In 1898, the discovery of two new elements, polonium and radium, reawakened interest in the topic of uranic rays discovered 2 years before by H. Becquerel. Radioactivity, a name coined by Marie Curie, became a major research field for decades. The contrasting personalities of Pierre Curie, already a first-rank physicist, and of the young Marie Curie-Sklodowska as they undertook their common work are described. It is shown how a well-chosen quantitative method and a systematic approach combining physics and chemistry led to the discovery within less than 1 year. The special role of radium and the determination of its atomic weight by Marie Curie followed by her long-term program for accumulating pure radium salts are emphasized. The first woman with a full professorship at a French University, Marie Curie created and managed the Radium Institute.

    Between 1927 and 1931 Marie Bonaparte had herself operated upon her clitoris three times. She did so against Freud's advice with whom she was in analysis. Among psychoanalysts these operations are still often regarded as "errors" or aberrations. But for Marie Bonaparte, who was in various ways familiar with physics and a somatic approach, surgery was the first choice, psychoanalysis only a possible alternative. She was not impressed by the scepticism of her colleagues, and adhered even more emphatically to her own strategy.

    Objective: To evaluate, by skin biopsy, dermal nerve fibers in 31 patients with 3 common Charcot-Marie-Tooth (CMT) genotypes (CMT1A, late-onset CMT1B, and CMTX1), and rarer forms of CMT caused by mutations in RAB7 (CMT2B), TRPV4 (CMT2C), and GDAP1 (AR-CMT2K) genes. Methods: We investigated axonal loss by quantifying Meissner corpuscles and intrapapillary myelinated endings and evaluated morphometric changes in myelinated dermal nerve fibers by measuring fiber caliber, internodal, and nodal gap length. Results: The density of both Meissner corpuscles and intrapapillary myelinated endings was reduced in skin samples from patients with CMT1A and all the other CMT genotypes. Nodal gaps were larger in all the CMT genotypes though widening was greater in CMT1A. Perhaps an altered communication between axons and glia may be a common feature for multiple forms of CMT. Internodal lengths were shorter in all the CMT genotypes, and patients with CMT1A had the shortest internodes of all our patients. The uniformly shortened internodes in all the CMT genotypes suggest that mutations in both myelin and axon genes may developmentally impede internode formation. The extent of internodal shortening and nodal gap widening are likely both important in determining nerve conduction velocities in CMT. Conclusions: This study extends the information gained from skin biopsies on morphologic abnormalities in various forms of CMT and provides insights into potential pathomechanisms of axonal and demyelinating CMT.

  4. VisitSense: Sensing Place Visit Patterns from Ambient Radio on Smartphones for Targeted Mobile Ads in Shopping Malls.

    Kim, Byoungjip; Kang, Seungwoo; Ha, Jin-Young; Song, Junehwa

    2015-01-01

    In this paper, we introduce a novel smartphone framework called VisitSense that automatically detects and predicts a smartphone user's place visits from ambient radio to enable behavioral targeting for mobile ads in large shopping malls. VisitSense enables mobile app developers to adopt visit-pattern-aware mobile advertising for shopping mall visitors in their apps. It also benefits mobile users by allowing them to receive highly relevant mobile ads that are aware of their place visit patterns in shopping malls. To achieve the goal, VisitSense employs accurate visit detection and prediction methods. For accurate visit detection, we develop a change-based detection method to take into consideration the stability change of ambient radio and the mobility change of users. It performs well in large shopping malls where ambient radio is quite noisy and causes existing algorithms to easily fail. In addition, we proposed a causality-based visit prediction model to capture the causality in the sequential visit patterns for effective prediction. We have developed a VisitSense prototype system, and a visit-pattern-aware mobile advertising application that is based on it. Furthermore, we deploy the system in the COEX Mall, one of the largest shopping malls in Korea, and conduct diverse experiments to show the effectiveness of VisitSense. PMID:26193275

    Background Midlife and older adults use shopping malls for walking, but little research has examined mall characteristics that contribute to their walkability. Methods We used modified versions of the Centers for Disease Control and Prevention (CDC)-Healthy Aging Research Network (HAN) Environmental Audit and the System for Observing Play and Recreation in Communities (SOPARC) tool to systematically observe 443 walkers in 10 shopping malls. We also observed 87 walkers in 6 community-based nonmall/nongym venues where older adults routinely walked for physical activity. Results All venues had public transit stops and accessible parking. All malls and 67% of nonmalls had wayfinding aids, and most venues (81%) had an established circuitous walking route and clean, well-maintained public restrooms (94%). All venues had level floor surfaces, and one-half had benches along the walking route. Venues varied in hours of access, programming, tripping hazards, traffic control near entrances, and lighting. Conclusions Despite diversity in location, size, and purpose, the mall and nonmall venues audited shared numerous environmental features known to promote walking in older adults and few barriers to walking. Future research should consider programmatic features and outreach strategies to expand the use of malls and other suitable public spaces for walking. PMID:26181907

    2015-08-30

    Compulsive buying is a relatively new psychopathological concept and very few data are currently available regarding the prevalence and validity of compulsive buying disorder. In this cross-sectional study, we establish the prevalence of compulsive buying disorder in shopping mall visitors and explore the construct validity of the concept using the revised version of the Edwards Compulsive Buying Scale in 1441 shopping mall visitors looking at shopping habits, current substance use (smoking, alcohol and illicit drug) and various psychological characteristics. Overall, 8.7% (95% CI: 7.3-10.3) of our sample was classified as having a compulsive buying disorder. Compulsive buyers were younger, less educated and more likely to be female than non-compulsive buyers. They were also more likely to have used licit and illicit substances. Compulsive buyers also reported higher levels of impulsivity and obsessive-compulsive symptoms, lower levels of well-being and self-esteem and more psychological distress. Finally, compulsive buyers were five times more likely to meet criteria for borderline personality disorder than non-compulsive buyers. Compulsive buying is a frequent disorder in shopping mall visitors and is associated with important and robust indicators of psychopathology thus supporting the validity of the construct.

Yet, through this neuroscience nurse's passion for her specialty, we share in her legacy through the annual Mary Glover Lecture, which was established by her parents after her death. The first Mary Glover Lecturer was Pamela Mitchell, a well-known neuroscience nurse from the School of Nursing at the University of Washington. She is leaving a multifaceted legacy through her research on intracranial pressure and quality of care as well as her books and her mentorship. Jessie Young has left a legacy as the founder and first president of the Canadian Association of Neuroscience Nurses (CANN). CANN is leaving a legacy with many firsts among Canadian nursing specialty organizations. Leaving a legacy is not just about donating money or writing a famous book. For most of us, our legacy comes in the little everyday things of life. Ask yourself, what is the legacy that you are leaving as a neuroscience nurse and as an individual?

    Marie Curie directed a research laboratory for 28 years. Between 1906 and 1934, forty five women worked under her guidance. Some were, and are, well-known in their own countries as their first woman full professor such as Ellen Gleditsch or Margaret von Wrangel, but for twenty eight of them, who were often French, nothing has ever been written. The strong presence of women in Marie Curie's laboratory has often been highlighted and has been considered as an exception, and the result of deliberate choice. Of course, these women did not choose this workplace by accident. They knew its director was a woman, a laureate of one, and after 1911, two Nobel Prizes, who was leading a well-equipped laboratory with an important radioactive source. But how did Marie Curie selected her collaborators among the many applications she received? Was her choice influenced by gender? A prosopographical research based on genealogical researches and new sources explains this presence contextually and sheds light on several questions : where did these women come from, what were their social and geographic origins, did they occupy any specific cultural or technical area inside Curie's lab, what future did they have after the laboratory? Through their lives, we can question the existence, or not, of a one profile of the female researcher in scientific areas in France.

    In order to understand the indoor air pollution of volatile organic compounds in furniture mall and to perform health risk assessment of chronic exposure to its workers, in this study, the air samples in a furniture mall in Tianjin were sampled in summer (June) and autumn (October) in 2011 and 2012, and the compositions of VOCs were investigated by using the method of reconcentration-GC-MS. The results showed that the indoor concentration of total pollutants was about 1.9 times higher than that of outdoor; the characterized odorous substances were dichloromethane, toluene, and alpha-pinene; aromatic compounds and halogenated alkane were detected in large amounts in furniture mall, and terpenes also occupied a certain proportion. The concentrations of benzene, toluene and xylene were significantly lower than the indoor air quality standards. There was a potential cancer risk of benzene and dichloromethane, the Lifetime Cancer Risks (LCR) of which were 1.24 x 10(-5) and 2.50 x 10(-5), respectively. The noncarcinogenic hazard index (HI) of TVOC was below 1, which was within the acceptable range. The health effects analysis showed that there was no partial correlation between the working seniority and heart rate, and pulmonary ventilation function. The biological monitoring and analysis of S-PMA and 8-OHdG in urine for the exposed group and control group showed that in the low-exposure conditions, smoking was an important factor affecting the concentration of S-PMA, but under conditions of higher-exposure, its influence was weakened; there was a positive correlation between S-PMA and 8-OHdG, there was also a correlation between S-PMA and sex, smoking and age; besides, there may be a correlation between S-PMA and the working seniority.

  10. Volatile organic compounds in a multi-storey shopping mall in guangzhou, South China

    NASA Astrophysics Data System (ADS)

    Tang, Jianhui; Chan, C. Y.; Wang, Xinming; Chan, L. Y.; Sheng, Guoying; Fu, Jiamo

    Volatile organic compounds (VOCs) specified in the USEPA TO-14 list were analysed in microenvironments of a multi-storey shopping mall in Guangzhou city, South China. The microenvironments studied include both indoor (department store, supermarket, fast-food court, electronic games room, children's playground, gallery and book store) and outdoor ones (rooftop and ground level entrance). The characteristics and concentration of VOCs varied widely in differing microenvironments. The average concentrations of the total VOCs in the indoor microenvironments ranged from 178.5 to 457.7 μg m -3 with a maximum of 596.8 μg m -3. The fast-food court and a leather products department store had the highest concentrations of benzene, toluene, ethylbenzene, xylenes and chlorinated hydrocarbons. A high level of 1,4-dichlorobenzene was found in all indoor microenvironments with an average of 12.3 μg m -3 and a maximum of 44.3 μg m -3. The ratios of average indoor to outdoor concentrations (I/O ratio) in all indoor microenvironments fell between 1 and 3, except an average of 24.6 and a maximum of 77.8 in the fashion department store for 1,4-dichlorobenzene. Indoor emission sources of monocyclic aromatic hydrocarbons in the shopping mall might include cooking stoves, leather products and building materials. Chlorinated hydrocarbons, however, were possibly connected with their use as cleaning agents or deodorizers.

    Concentrations of BTX (benzene, toluene and xylene), total volatile organic compounds (TVOC), formaldehyde and other carbonyl compounds were measured in different sections of a furniture mall in Beijing. The overall indoor concentrations (mean +/- standard deviation) of formaldehyde, benzene, toluene, xylene, and TVOC were (0.37 +/- 0.08), (0.04 +/- 0.03), (0.19 +/- 0.16), (0.47 +/- 0.57), and (2.76 +/- 2.18) mg/m3, respectively. Indoor concentrations of formaldehyde, xylene and TVOC were 22, 46 and 34 times higher than the corresponding outdoor concentrations respectively. Concentrations of formaldehyde, xylene and TVOC were much higher than the standard limits regulated in the national "indoor air quality standard" (GB/T 18883-2002), and the highest concentrations of formaldehyde and TVOC exceeded the standard limit 5.1 and 14.8 times respectively. Total concentration of carbonyl compounds was (689.3 +/- 94.8) microg/m3, which was 5 times higher than that outdoors. Of the carbonyls, formaldehyde and acetaldehyde were found to be the most abundant, together accounting for over 75% of the total carbonyl concentrations. Acetone, C4 carbonyls (methacrolein, methyl ethyl ketone, butanal), and hexanal also occurred at relatively high concentrations. In conclusion, indoor air pollution is serious in the furniture mall.

  12. Automatic detection of suspicious behavior of pickpockets with track-based features in a shopping mall

    Proactive detection of incidents is required to decrease the cost of security incidents. This paper focusses on the automatic early detection of suspicious behavior of pickpockets with track-based features in a crowded shopping mall. Our method consists of several steps: pedestrian tracking, feature computation and pickpocket recognition. This is challenging because the environment is crowded, people move freely through areas which cannot be covered by a single camera, because the actual snatch is a subtle action, and because collaboration is complex social behavior. We carried out an experiment with more than 20 validated pickpocket incidents. We used a top-down approach to translate expert knowledge in features and rules, and a bottom-up approach to learn discriminating patterns with a classifier. The classifier was used to separate the pickpockets from normal passers-by who are shopping in the mall. We performed a cross validation to train and evaluate our system. In this paper, we describe our method, identify the most valuable features, and analyze the results that were obtained in the experiment. We estimate the quality of these features and the performance of automatic detection of (collaborating) pickpockets. The results show that many of the pickpockets can be detected at a low false alarm rate.

    Heritable diseases of the peripheral nerves (Charcot-Marie-Tooth disease [CMT]) affect the motor units and sensory nerves, and they are among the most prevalent genetic conditions in the pediatric patient population. The typical clinical presentation includes distal muscle weakness and atrophy, but the severity and progression are largely variable. Improvements in supportive treatment have led to better preservation of patients' motor functions. More than 80 genes have been associated with CMT. These genetic discoveries, along with the developments of cellular and transgenic disease models, have allowed clinicians to better understand the disease mechanisms, which should lead to more specific treatments.

  3. Centrifuges cut oil change costs in half at NYC shopping mall

    Gustafson, B.J.

    1983-09-01

    This article describes the use of centrifuges in five double turbocharged engines in an energy plant at a New York City shopping mall. The result of the use of the centrifuges has been a marked decrease in the use of lubricating oil. While the mechanics formerly changed oil and filters twice a year, they now only change it when the oil analysis says they should. So far it has been estimated that an oil change is needed only once a year, cutting oil and filter usage in half. An estimated annual saving of $1000 for lubricating oil and $476 for the 28 filters on each engine, which is a direct savings of $7380 per year for all five engines.

    Charcot-Marie-Tooth (CMT) disease or hereditary motor and sensory neuropathy (HMSN) is a genetically heterogeneous group of conditions that affect the peripheral nervous system. The disease is characterized by degeneration or abnormal development of peripheral nerves and exhibits a range of patterns of genetic transmission. In the majority of cases, CMT first appears in infancy, and its manifestations include clumsiness of gait, predominantly distal muscular atrophy of the limbs, and deformity of the feet in the form of foot drop. It can be classified according to the pattern of transmission (autosomal dominant, autosomal recessive, or X linked), according to electrophysiological findings (demyelinating or axonal), or according to the causative mutant gene. The classification of CMT is complex and undergoes constant revision as new genes and mutations are discovered. In this paper, we review the most efficient diagnostic algorithms for the molecular diagnosis of CMT, which are based on clinical and electrophysiological data. PMID:19826499

    The Galactic Cosmic Ray spectra in Mars orbit were generated with the recently expanded HZETRN (High Z and Energy Transport) and QMSFRG (Quantum Multiple-Scattering theory of nuclear Fragmentation) model calculations. These model calculations are compared with the first eighteen months of measured data from the MARIE (Martian Radiation Environment Experiment) instrument onboard the 2001 Mars Odyssey spacecraft that is currently in Martian orbit. The dose rates observed by the MARIE instrument are within 10% of the model calculated predictions. Model calculations are compared with the MARIE measurements of dose, dose-equivalent values, along with the available particle flux distribution. Model calculated particle flux includes GCR elemental composition of atomic number, Z = 1-28 and mass number, A = 1-58. Particle flux calculations specific for the current MARIE mapping period are reviewed and presented.

    As society grapples with contemporary moral questions raised by the barring of HIV-infected people from jobs and even crossing some national borders, it is probably useful to re-examine the case of Typhoid Mary. The case of Mary Mallon shows how an earlier age resolved the conflict that arises when society's right to protect itself from unnecessary exposure to disease impinges on the liberty of individual citizens.

    Sister Mary Joseph nodules represent metastatic cancer of the umbilicus. More than half of these cases are attributable to gastrointestinal malignancies including gastric, colonic, and pancreatic cancer. In addition, gynecologic (ovarian, uterine cancer), unknown primary tumors, and, rarely, bladder or respiratory malignancies may cause umbilical metastasis. We report the case of a Sister Mary Joseph nodule originating from a hilar cholangiocarcinoma. Umbilical nodules should prompt clinical evaluation, as these tumors are usually associated with poor prognosis. PMID:27144207

    The confluence of MaRIE (Matter-Radiation Interactions in Extreme) and extreme (exascale) computing timelines offers a unique opportunity in co-designing the elements of materials discovery, with theory and high performance computing, itself co-designed by constrained optimization of hardware and software, and experiments. MaRIE's theory, modeling, and computation (TMC) roadmap efforts have paralleled 'MaRIE First Experiments' science activities in the areas of materials dynamics, irradiated materials and complex functional materials in extreme conditions. The documents that follow this executive summary describe in detail for each of these areas the current state of the art, the gaps that exist and the road map to MaRIE and beyond. Here we integrate the various elements to articulate an overarching theme related to the role and consequences of heterogeneities which manifest as competing states in a complex energy landscape. MaRIE experiments will locate, measure and follow the dynamical evolution of these heterogeneities. Our TMC vision spans the various pillar science and highlights the key theoretical and experimental challenges. We also present a theory, modeling and computation roadmap of the path to and beyond MaRIE in each of the science areas.

  19. Referrals to the Marie Curie nursing service in North Yorkshire.

    Hanratty, B; Feather, J; Ward, C

    2000-01-01

    District and Marie Curie nurses participated in a small-scale study to describe referrals to a Marie Curie service in one English health district over a 3-month period. The number of new patients referred was small; they were geographically clustered and had widely differing life expectancies. Anecdotal reports of difficulties with the 'Nurselink' referral system were not confirmed, and in situations where the system was in operation, Marie Curie nurses were more likely to speak directly to the referring nurse. The most frequently cited reason for referral was general nursing needs; however, Marie Curie nurses felt that they were most often involved to provide family support. These findings suggest that there may not be a shared understanding of the Marie Curie nurse's role, and that equity in community palliative nursing care merits examination. Defining and publicizing the role of the Marie Curie nurse, providing guidance for referrals and prioritizing communication between professionals are proposed not only to enhance the service locally but to ensure that the service is available to all. This article illustrates the value of research to identify ways to improve service delivery.

  20. [Pathology of Charcot-Marie-Tooth Disease].

    Although genetic testing is available, nerve biopsy is useful in selected patients for the diagnosis of Charcot-Marie-Tooth disease (CMT). These are sporadic cases of hereditary neuropathy, or familial cases in which genetic testing is negative. CMT is caused by mutations of various genes. The pathological features of CMT have mostly been investigated using nerve biopsy, which may shed light on the presumed functions of mutated gene products. PMP22 duplication in CMT1A induces numerous large onion bulb lesions (OB). Compared to chronic inflammatory demyelinating polyradiculoneuropathy, the differential features of CMT1A are patchy distribution of OB and non-inflammatory lesions. CMT1B also manifests as OB, but presents abnormal compaction of myelin sheaths caused by uncompacted myelin or excessive myelin folding. CMT2 includes axonal neuropathies and many causative genes have been found. CMT2A (MFN2 mutation) shows abnormal mitochondria with a spherical morphology instead of tubular in the longitudinal direction. CMT4 consists of autosomal recessive forms with demyelinating pathology. Most subtypes have mutations of genes relating to myelin maintenance, and pathologically, they show abnormal folding of the myelin structure.

    2011-01-01

    The paper presents a family with hereditary transmitted Marie-Sainton dysplasia affecting the father and his both children. This is a rare syndrome presenting an autosomal pattern of inheritance, characterized by a generalized defect in both membranous and endochondral bone formation resulting in clavicular aplasia, delayed ossification of the fontanelles and the sutures of the skull and prolonged retention of deciduous dentition with delayed eruption of the permanent teeth. The diagnosis is suggested by more or less complete clinical picture and confirmed by multiple radiological explorations (skull, thorax, spinal column, pelvis) and genetical examination. The genetic mutation for cleidocranial dysplasia (CCD) is found on chromosome six and is called CBFA1 (short for core biding factor al or RUNX2) and is the only gene known to be associated with CCD. The normal version of CBFA1 acts to induce osteoblasts which are the type of cells that lay down bone. Although associated psychosocial disorders can occur, the prognosis and life expectancy of this condition are favorable being conditioned however by the complexity of orthodontic procedures which are determinant for these patients life quality.

    1994-12-01

    The Laboratory for Astrophysics (LfA) at the National Air and Space Museum (NASM) is proposing a new exhibit: an outdoor model of the Solar System on the National Mall, dedicated to the Spirit of Human Exploration. At one ten- billionth of the size of the actual Solar System, the model would provide a unique educational tool to illustrate the vast distances that characterize our local corner of the universe. Mounted on pedestals along a gravel walkway between the U.S. Capitol and the Washington Monument for 0.6 kilometers (an easy walk for over 10 million visitors a year), plaques would tactilely depict the scaled sizes and distances of the Sun, the planets, and their larger satellites in polished bronze. Porcelain enamel insets in the bronze would display color photographs, language-independent educational pictograms, and an international pictoral listing of spacecraft that have visited these bodies. Designed for a multi-cultural audience of varied ages and educational backgrounds, and with easy access to persons with disabilities, the model would celebrate humanity's long and ongoing relationship with Earth's nearest neighbors. Ideally, this exhibit will be supported by teacher-activity packets, self-guided tours, exportable models, computer software, and multi-lingual audio programs. This proposal is being partially funded by the NASA Solar Systems division.

    The food court at a shopping mall is a potential transfer point for pathogenic microbes, but to date, this environment has not been the subject of detailed molecular microbiological study. We used a combination of culture-based and culture-independent approaches to investigate the types and numbers of bacteria present on food court tables, and on a food court cleaning cloth. Bacteria were found at 10²-10⁵ c.f.u./m² on food court tables and 10¹⁰ c.f.u./m² on the cleaning cloth. Tag-pyrosequencing of amplified 16S rRNA genes revealed that the dominant bacterial types on the cleaning cloth were genera known to include pathogenic species (Stenotrophomonas, Aeromonas), and that these genera were also evident at lower levels on table surfaces, suggesting possible cross-contamination. The evidence suggests a public health threat is posed by bacteria in the food court, and that this may be due to cross-contamination between cleaning equipment and table surfaces.

  4. Soils of Marie Byrd Land, West Antarctica

    2013-10-01

    Soils of Marie Byrd Land-one of the remotest and difficultly accessible regions of Antarctica-were investigated in the area of the mothballed Russkaya station located to the south of 74° S. Despite the extremely severe wind regime (the average wind velocity is 13 m/s, and the maximum wind velocity is up to 60 m/s), the projective cover of vegetation in the area of the station averages 25-40% and reaches 60-80% in some places. The phenomena of physical weathering of the bedrock-exfoliation, stone pavements, residual rocks exposed by wind (hoodoos), and others-are clearly manifested. In most of the described soils, normal organic and organomineral horizons are absent. The soil profiles represent the mixture of the residues of mosses and lichens and the gravelly eluvium. The fine earth material is blown out of the surface horizons by strong winds; its residual accumulation takes place in the middle and lower parts of the profiles. The classification position of these soils is open to argument; they are close to Petrozems and Lithozems. Most of the profiles are underlain by the massive or slightly disintegrated bedrock with dry permafrost at a depth of 20 to 50 cm. Soils with dry permafrost comprise about 75% of the surveyed area. In separate loci in the depressions of the local mesorelief and on gentle slopes, the soils with clearly expressed cryoturbation features are developed; their profiles are underlain by the ice-rich permafrost and compose about 15% of the surveyed area. Anthropogenically disturbed soils and soils polluted with petroleum hydrocarbons, heavy metals, and other pollutants occupy about 10% of the surveyed area.

    2013-06-01

    Two series of sodium carboxymethyl celluloses (NaCMCs) derived from microcrystalline cellulose (Avicel samples) and cotton linters (BWL samples) with average degrees of substitution (DS) ranging from DS=0.45 to DS=1.55 were characterized by size exclusion chromatography with multi-angle laser light scattering detection (SEC-MALLS) in 100 mmol/L aqueous ammonium acetate (NH4OAc) as vaporizable eluent system. The application of vaporizable NH4OAc allows future use of the eluent system in two-dimensional separations employing evaporative light scattering detection (ELSD). The losses of samples during filtration and during the chromatographic experiment were determined. The scaling exponent as of the relation [Formula: see text] was approx. 0.61, showing that NaCMCs exhibit an expanded coil conformation in solution. No systematic dependencies of as on DS were observed. The dependences of molar mass on SEC-elution volume for samples of different DS can be well described by a common calibration curve, which is of advantage, as it allows the determination of molar masses of unknown samples by using the same calibration curve, irrespective of the DS of the NaCMC sample. Since no commercial NaCMC standards are available, correction factors were determined allowing converting a pullulan based calibration curve into a NaCMC calibration using the broad calibration approach. The weight average molar masses derived using the so established calibration curve closely agree with the ones determined by light scattering, proving the accuracy of the correction factors determined.

  15. Experimental Physical Sciences Vistas: MaRIE (draft)

    2010-09-08

    To achieve breakthrough scientific discoveries in the 21st century, a convergence and integration of world-leading experimental facilities and capabilities with theory, modeling, and simulation is necessary. In this issue of Experimental Physical Sciences Vistas, I am excited to present our plans for Los Alamos National Laboratory's future flagship experimental facility, MaRIE (Matter-Radiation Interactions in Extremes). MaRIE is a facility that will provide transformational understanding of matter in extreme conditions required to reduce or resolve key weapons performance uncertainties, develop the materials needed for advanced energy systems, and transform our ability to create materials by design. Our unique role in materials science starting with the Manhattan Project has positioned us well to develop a contemporary materials strategy pushing the frontiers of controlled functionality - the design and tailoring of a material for the unique demands of a specific application. Controlled functionality requires improvement in understanding of the structure and properties of materials in order to synthesize and process materials with unique characteristics. In the nuclear weapons program today, improving data and models to increase confidence in the stockpile can take years from concept to new knowledge. Our goal with MaRIE is to accelerate this process by enhancing predictive capability - the ability to compute a priori the observables of an experiment or test and pertinent confidence intervals using verified and validated simulation tools. It is a science-based approach that includes the use of advanced experimental tools, theoretical models, and multi-physics codes, simultaneously dealing with multiple aspects of physical operation of a system that are needed to develop an increasingly mature predictive capability. This same approach is needed to accelerate improvements to other systems such as nuclear reactors. MaRIE will be valuable to many national security

    This paper discusses the genesis of the famous story of Frankenstein which arose from a dream experienced by Mary Shelley whilst on a holiday shared with her husband Percy Shelley, Lord Byron, Dr Polidori and her step sister Claire Clairmont. The novel relates how the creature created by Victor Frankenstein horrifies him, is rejected by him and called a monster. The monster's ensuing despair and subsequent murderousness is eloquently described. The whole book is clearly connected to Mary Shelley's experience as an infant whose mother died after giving birth to her and her subsequent loss, as a mother, of her own new born infant. It is suggested that the novel imaginatively describes what it is to have been primarily rejected as an infant and to feel regarded as a monster. PMID:25610958

    1994-01-01

    The Federal Aviation Administration (FAA) owns or operates airway support facilities near Saint Marys along the Yukon River in west-central Alaska. The FAA is evaluating the severity of environmental contamination and options for remediation of environmental contamination at their facilities. Saint Marys is on a flood plain near the continence of the Yukon and Andreafsky Rivers and has long cold winters and short summers. Residents obtain their drinking water from an infiltration gallery fed by a creek near the village. Surface spills and disposal of hazardous materials combined with potential flooding may affect the quality of the surface and ground water. Alternative drinking-water sources are available, but would likely cost more than existing supplies to develop.

  19. The Pasteurization of Marie Curie: A (meta)biographical experiment.

    2015-08-01

    Biographies of scientists occupy a liminal space, highly popular with general readers but questioned in academia. Nonetheless, in recent years, historians of science have not only embraced the genre with more enthusiasm and less guilt, they have also turned to the metabiography in order to renew the study and story of scientists' roles. This essay focuses on Marie Curie, the world's most famous female scientist, in order to unpack some of the theoretical and methodological claims of the science biography, and especially to address the sexing mechanisms at play in the construction of the biographical subject. Pierre Curie (1923), Marie's biography of her husband Pierre, paid tribute to her dead husband and collaborator, but also allowed Curie a legitimate outlet to construct her own persona and legacy. Categories such as personhood, person, and persona are not only central to the biography genre but also are essential to the sense of self and self-fashioning of scientists. Looking at how Marie Curie negotiated these categories in Pierre Curie not only gives new insight into Curie's self-fashioning strategies but may also shed some light on the more general analytical lacunae of the science biography.

  20. The St. Marys River, Michigan: An ecological profile

    Duffy, W.G.; Batterson, T.R.; McNabb, C.D.

    1987-05-01

    St. Marys River, the single outlet from Lake Superior, flows between Michigan and Ontario and has formed the International Border between the United States and Canada since 1783. Although the riverbed and a major rapids system have been modified to accommodate commercial navigation and for hydroelectric generation, the St. Marys River retains more of its biological and physicochemical integrity than any other Laurentian Great Lakes connecting channel. This oligotrophic lake's cold, well-oxygenated water contributes >90% of the river's annual flow and has a major influence on the evolution of its biological communities. This monograph reviews the published and unpublished ecological information available for the St. Marys River. The authors begin by reviewing the geologic history, human exploration, and settlement of the region, then proceed to a description of the physical and chamical characteristics of the river. The third chapter describes the biological communities presently inhabiting the river. A fourth chapter synthesizes ecological relationships within the river, emphasizing detrital food webs and trophic interactions. In the final chapter, anthropogenic influences on the river ecosystem are reviewed and various natural resource management strategies suggested.

  1. View of 'Cape St. Mary' from 'Cape Verde'

    2006-01-01

    As part of its investigation of 'Victoria Crater,' NASA's Mars Exploration Rover Opportunity examined a promontory called 'Cape St. Mary' from the from the vantage point of 'Cape Verde,' the next promontory counterclockwise around the crater's deeply scalloped rim. This view of Cape St. Mary combines several exposures taken by the rover's panoramic camera into an approximately true-color mosaic.

    The upper portion of the crater wall contains a jumble of material tossed outward by the impact that excavated the crater. This vertical cross-section through the blanket of ejected material surrounding the crater was exposed by erosion that expanded the crater outward from its original diameter, according to scientists' interpretation of the observations. Below the jumbled material in the upper part of the wall are layers that survive relatively intact from before the crater-causing impact. Near the base of the Cape St. Mary cliff are layers with a pattern called 'crossbedding,' intersecting with each other at angles, rather than parallel to each other. Large-scale crossbedding can result from material being deposited as wind-blown dunes.

    The images combined into this mosaic were taken during the 970th Martian day, or sol, of Opportunity's Mars-surface mission (Oct. 16, 2006). The panoramic camera took them through the camera's 750-nanometer, 530-nanometer and 430-nanometer filters.

    2013-01-01

    A large-scale subjective survey was conducted in six shopping malls in Harbin City, China, to determine the influence of social and behavioural characteristics of users on their evaluation of subjective loudness and acoustic comfort. The analysis of social characteristics shows that evaluation of subjective loudness is influenced by income and occupation, with correlation coefficients or contingency coefficients of 0.10 to 0.40 (p<0.05 or p<0.01). Meanwhile, evaluation of acoustic comfort evaluation is influenced by income, education level, and occupation, with correlation coefficients or contingency coefficients of 0.10 to 0.60 (p<0.05 or p<0.01). The effect of gender and age on evaluation of subjective loudness and acoustic comfort is statistically insignificant. The effects of occupation are mainly caused by the differences in income and education level, in which the effects of income are greater than that of education level. In terms of behavioural characteristics, evaluation of subjective loudness is influenced by the reason for visit, frequency of visit, and length of stay, with correlation coefficients or contingency coefficients of 0.10 to 0.40 (p<0.05 or p<0.01). Evaluation of acoustic comfort is influenced by the reason for visit to the site, the frequency of visit, length of stay, and also season of visit, with correlation coefficients of 0.10 to 0.30 (p<0.05 or p<0.01). In particular, users who are waiting for someone show lower evaluation of acoustic comfort, whereas users who go to shopping malls more than once a month show higher evaluation of acoustic comfort. On the contrary, the influence of the period of visit and the accompanying persons are found insignificant.

    This paper examines a pamphlet entitled Britain's Siberia. The High Statistics of Insanity Explained by a Certified Lunatic. Research has revealed that the writer was Mary Coutts and that she had been a detained patient in the Aberdeen Royal Asylum. The paper analyses what Coutts had to say about her experiences and compares this to the official asylum records and what they reveal about her inmate stay. The paper also relates Coutts' account to that of other patients who have written about their experiences. As one of the few women to have left a record of life in the asylum, Coutts' story is of particular interest.

    Mary Ellen Avery's research is recognized as a milestone in biomedical research. She had discovered the underlying cause of hyaline membrane disease, surfactant deficiency, fostering ever more vigorous efforts to reduce neonatal mortality in the burgeoning practice of Neonatology. Neonatology is the only clinical discipline that began as an experiment, making it a model for biomedical research. Avery knew that the concerted effort to treat preterm newborns could potentially do more harm than good, violating her oath to Hippocrates, if not held to the highest scientific standards. She remained true to that pledge throughout her career, as recounted in this Review. PMID:24804189

    Surface exposure ages of glacial deposits in the Ford Ranges of western Marie Byrd Land indicate continuous thinning of the West Antarctic Ice Sheet by more than 700 meters near the coast throughout the past 10,000 years. Deglaciation lagged the disappearance of ice sheets in the Northern Hemisphere by thousands of years and may still be under way. These results provide further evidence that parts of the West Antarctic Ice Sheet are on a long-term trajectory of decline. West Antarctic melting contributed water to the oceans in the late Holocene and may continue to do so in the future.

    This study determines the impact of symptoms associated with Charcot-Marie-Tooth disease on quality-of-life. Charcot-Marie-Tooth patients in the Inherited Neuropathies Consortium Rare Diseases Clinical Research Network Contact Registry were surveyed. The survey inquired about 214 symptoms and 20 themes previously identified as important to Charcot-Marie-Tooth patients through patient interviews. Symptom population impact was calculated as the prevalence multiplied by the relative importance of each symptom identified. Prevalence and symptom impact were analyzed by age, symptom duration, gender, Charcot-Marie-Tooth type, and employment status. 407 participants returned the survey, identifying foot and ankle weakness (99.7%) and impaired balance (98.6%) as the most prevalent themes. Foot and ankle weakness and limitations with mobility were the themes with the highest impact. Both symptom prevalence and impact gradually increased with age and symptom duration. Several themes were more prevalent in women with Charcot-Marie-Tooth, including activity limitations, pain, fatigue, hip-thigh weakness, and gastrointestinal issues. All of the themes, except emotional or body image issues, were more prevalent among unemployed individuals. There were minimal differences in symptom prevalence between Charcot-Marie-Tooth types. There are multiple symptoms that impact Charcot-Marie-Tooth quality-of-life in adults. These symptoms have different levels of importance, are readily recognized by patients, and represent critical areas of Charcot-Marie-Tooth health.

    The 2001 Mars Odyssey spacecraft was launched towards Mars on April 7, 2001. Onboard the spacecraft is the Martian radiation environment experiment (MARIE), which is designed to measure the background radiation environment due to galactic cosmic rays (GCR) and solar protons in the 20-500 MeV/n energy range. We present an approach for developing a space radiation-shielding model of the spacecraft that includes the MARIE instrument in the current mapping phase orientation. A discussion is presented describing the development and methodology used to construct the shielding model. For a given GCR model environment, using the current MARIE shielding model and the high-energy particle transport codes, dose rate values are compared with MARIE measurements during the early mapping phase in Mars orbit. The results show good agreement between the model calculations and the MARIE measurements as presented for the March 2002 dataset.

    Suspicious circumstances surrounding the death of wealthy socialite Mary Lily "Lil'" Kenan Flagler Bingham in 1917 prompted a secret autopsy conducted by renowned physicians at the request of her relatives. Mrs Bingham, who was formerly married to railroad magnate, Henry Flagler, was among America's richest people at the time of her death. Mary Lil's untimely death occurred approximately six months after her marriage to Judge Robert "Bob" Worth Bingham, a college boyfriend whom she married three years after Flagler's death. In order to establish Mary Lil's medical condition prior to her death, a book about Mary Lil's life written by Pulitzer Prize author, David Chandler and articles from the New York Times; The Louisville Courier Journal, a Kentucky newspaper; and Mary Lil's hometown newspaper, The Morning Star, in Wilmington, North Carolina were examined. Although a team of medical experts performed a secret autopsy following her death and released their findings to her family, the examination and tests results remain undisclosed to the public.

    Marie Bonaparte (1882-1962) played a critical role in the development of psychoanalysis in France. Her clinical activity is not well known yet she was one of the first female French psychoanalysts. The journalist-writers Alice and Valerio Jahier were Bonaparte's first two patients. She conducted this dual analysis with Rudolph Loewenstein (1898-1976). Alice and Valerio exchanged analysts on several occasions. During his analysis, Valerio began corresponding with Italo Svevo (1861-1928), the author of La Coscienza di Zeno, who imparted his doubts on the therapeutic merits of psychoanalysis. Valerio described his difficult analysis in his letters to Svevo. Bonaparte consulted Freud on the subject, but was not able to prevent Valerio's suicide in 1939. The Princess of Greece encouraged Alice in her vocation as a writer and enabled her to benefit from her connections in literary circles. On the margins of this unpublished story of the two analyses, which is based on archived documents recently made available, we discover the importance of the links which were formed - around Marie Bonaparte - between psychoanalysis and literature. In addition to Italo Svevo, we come across the acerbic writer, Maurice Sachs, as well as the famous novelist, Stefan Zweig. PMID:20840644

    Los Alamos National Laboratory's proposed signature facility, MaRIE, will provide scientists and engineers with new capabilities for modeling, synthesizing, examining, and testing materials of the future that will enhance the USA's energy security and national security. In the area of fusion power, the development of new structural alloys with better tolerance to the harsh radiation environments expected in fusion reactors will lead to improved safety and lower operating costs. The Fission and Fusion Materials Facility (F{sup 3}), one of three pillars of the proposed MaRIE facility, will offer researchers unprecedented access to a neutron radiation environment so that the effects of radiation damage on materials can be measured in-situ, during irradiation. The calculated radiation damage conditions within the F{sup 3} match, in many respects, that of a fusion reactor first wall, making it well suited for testing fusion materials. Here we report in particular on two important characteristics of the radiation environment with relevancy to radiation damage: the primary knock-on atom spectrum and the impact of the pulse structure of the proton beam on temporal characteristics of the atomic displacement rate. With respect to both of these, analyses show the F{sup 3} has conditions that are consistent with those of a steady-state fusion reactor first wall.

    To date, no single diagnosis has unified the psychiatric illness and the numerous poorly defined physical complaints that Mary Lincoln (née Todd, 1818-1882) suffered in adulthood. Here, I show that her physical ailments spanned 30 years and included sore mouth, pallor, paresthesias, the Lhermitte symptom, fever, headaches, fatigue, resting tachycardia, edema, episodic weight loss, progressive weakness, ataxia, and visual impairment. Long thought hypochondriacal, these findings, plus their time course and her psychopathology (irritability, delusions, hallucinations, with preserved clarity), are all consistent with vitamin B12 deficiency. Pernicious anemia most probably caused this deficiency: she lacked risk factors for other causes, and her consanguineous parents both derived from a region of Scotland having a high incidence of pernicious anemia. A diagnosis of chronic multisystem pernicious anemia would clarify the conduct of Mary Lincoln as First Lady and widow, and illuminate challenges faced by her husband, President Abraham Lincoln. Her case highlights many forgotten features of the natural history of untreated pernicious anemia and is unique in the medical literature in demonstrating such a course extending over a lifetime.

    The adoption and deployment of 3DTV can be seen as a major step in the history of television, comparable to the transition from analogue to digital and standard to high definition TV. Although 3D is expected to emerge from the cinema to peoples’ home, there is still a lack of knowledge on how people (future end users) perceive 3DTV and how this influences their viewing experience as well as their acceptance of 3DTV. Within this paper, findings from a three-day field evaluation study on people’s 3DTV experiences, focusing on the feeling of sickness and presence, are presented. Contrary to the traditional controlled laboratory setting, the study was conducted in the public setting of a shopping center and involved 700 participants. The study revealed initial insights on users’ feeling of presence and sickness when watching 3DTV content. Results from this explorative study show that most of the participants reported symptoms of sickness after watching 3DTV with an effect of gender and age on the reported feeling of sickness. Our results further suggest that the users’ previous experience with 3D content has an influence on how realistic people rate the viewing experience and how involved they feel. The particularities of the study environment, a shopping mall, are reflected in our findings and future research directions and action points for investigating people’s viewing experiences of 3DTV are summarized.

    A straight forward strategy of heparin surface grafting employs a terminal reactive-aldehyde group introduced through nitrous acid depolymerization. An advanced method that allows simultaneously monitoring of both heparin molar mass and monomer/aldehyde ratio by size exclusion chromatography, multi-angle laser light scattering and UV-absorbance (SEC-MALLS-UV) has been developed to improve upon heparin surface grafting. Advancements over older methods allow quantitative characterization by direct (aldehyde absorbance) and indirect (Schiff-based absorbance) evaluation of terminal functional aldehydes. The indirect quantitation of functional aldehydes through labeling with aniline (and the formation of a Schiff-base) allows independent quantitation of both polymer mass and terminal functional groups with the applicable UV mass extinction coefficients determined. The protocol was subsequently used to synthesize an optimized heparin-aldehyde that had minimal polydispersity (PDI<2) and high reaction yields (yield >60% by mass). The 8 kDa weight averaged molar mass heparin-aldehyde was then grafted on polycaprolactone (PCL), a common implant material. This optimized heparin-aldehyde retained its antithrombin activity, assessed in freshly drawn blood or surface immobilized on PCL films. Anticoagulant activity was equal to or better than the 24 kDa unmodified heparin it was fragmented from. PMID:26052108

    The objective of this study was to qualify and quantify the specific polysaccharides in Panax spp. The analyses of specific polysaccharides were performed by using GC-MS, saccharide mapping and high performance size exclusion chromatography (HPSEC) coupled with multi angle laser light scattering (MALLS) and refractive index detector (RID). Results showed that compositional monosaccharides were the same in different species of Panax and composed of rhamnose, arabinose, galacturonic acid, mannose, glucose, and galactose. Saccharide mapping results showed that glycosides linkages, which existed in specific polysaccharides from Panax spp., were similar. Additionally, the content of specific polysaccharides of P. ginseng, P. notoginseng and P. quinquefolium were 17.9-20.5mg/g, 11.9-15.0mg/g, and 9.9-13.3mg/g, respectively. P. ginseng, P. notoginseng, and P. quinquefolium could be clustered into three groups using both hierarchical cluster analysis and principal component analysis. The results possessed great potential in characterization and content determination of specific polysaccharides in Panax spp. PMID:27561470

    While thorough investigation of many aspects of contemporary scientific developments and Mary Shelley's personal history have provided illuminating contexts for the study of Frankenstein, the activities of the Royal Humane Society, and other bodies and individuals who pioneered and publicized resuscitation techniques, have been comparatively neglected. Here we find a richly documented, highly conspicuous area of scientific endeavour, which generated much excitement in life and literature from the last quarter of the eighteenth century onwards. There are three major points of contact with Frankenstein: Victor Frankenstein's revival of dead tissue to make his creature; the frequent occurrences of unconsciousness and asphyxia, both in the novel and in Mary Shelley's family during the period leading up to its composition, and the widely differing degrees of competence and success with which they are treated; and the possibility that resuscitative techniques were used to revive Mary Shelley's mother, Mary Wollstonecraft, after a suicide attempt. The impact on Frankenstein of Mary Shelley's lifelong distress at the role she played in bringing about her mother's death in childbirth has been thoroughly canvassed by other critics, notably Anne Mellor, but the thought that Mary Shelley, who was herself conceived after her mother's second suicide attempt, might be, in a sense, a child of the dead adds a further turn to the Gothic screw. This study traces a hitherto unexplored intersection between Mary Shelley's first novel and her family history, as well as showing how it launches a formidable attack on the shady ethics and inconsiderate arrogance of some early resuscitators.

    Mary Jane Seacole was born Mary Grant in Kingston Jamaica in 1805. Her father was a Scottish army officer and her mother a free Jamaican black, (slavery was not fully abolished in Jamaica until 1838). Her mother ran a hotel, Blundell Hall, in Kingston and was a traditional healer. Her skill as a nurse was much appreciated, as many of her residents were disabled British soldiers and sailors. It was from her mother that Mary learned the art of patient care, and she also assisted at the local British army hospital.

    Mary Breckinridge, founder of The Frontier Nursing Service, employed ethnographic methodologies--participant observation, interviewing and fieldwork--as foundation efforts toward construction of highly responsive health-service systems, developed under circumstances of duress, e.g. after World War I and pre-industrial Appalachia. In culturally representing the Appalachian, she drew upon two vast resources, her first-hand field experience as well as her considerable rhetorical skill. She narrated and described an enormity of selected 'realities' of Appalachian life with immediacy of detail and nonpatronizing sensitivity for 'insider' perspectives. In an era of transition with few indigenous cultural writers, Breckinridge capitalized on her family heritage in Appalachia, which further underscored the intimacy and authenticity of her accounts. As portrayed in her autobiography, crosscultural encounters of one kind and time or another supplied an infrastructure of longstanding meaning throughout her life. The final and lasting impression is that, in both skills and orientation, Breckinridge's were essentially those of the ethnographer.

  3. Therapeutic options in Charcot-Marie-Tooth diseases.

    2015-04-01

    Charcot-Marie-Tooth (CMT) diseases represent a heterogeneous genetic disorder (more than 80 genes are implicated in these inherited neuropathies), but sharing a similar phenotype. In recent years, advances in molecular genetics and molecular biology, and also the development of various animal models of CMT, have led to a better understanding. Taken together, this knowledge represents a prerequisite for the development of future therapies in CMT, and in peripheral nervous system disorders in general. The efficacy of various substances has been shown in vitro and also in vivo (in animal models); but, no significant positive effect has yet been confirmed in humans. However, some of these trials are still in development, and we may expect positive results in the future. Although CMT is still an incurable disease, symptomatic treatments (physiotherapy, surgery, analgesic, etc.) are crucial to improve the quality of life of CMT patients.

    There have been suggestions from previous studies that patients with Charcot-Marie-Tooth disease (CMT) have weaker dominant hand muscles. Since all studies to date have included a heterogeneous group of CMT patients we decided to analyse hand strength in 43 patients with CMT1X. We recorded handedness and the MRC scores for the first dorsal interosseous and abductor pollicis brevis muscles, median and ulnar nerve compound motor action potentials and conduction velocities in dominant and non-dominant hands. Twenty-two CMT1X patients (51%) had a weaker dominant hand; none had a stronger dominant hand. Mean MRC scores were significantly higher for first dorsal interosseous and abductor pollicis brevis in non-dominant hands compared to dominant hands. Median nerve compound motor action potentials were significantly reduced in dominant compared to non-dominant hands. We conclude that the dominant hand is weaker than the non-dominant hand in patients with CMT1X.

She was the first woman Shuttle pilot on STS-63 in 1995, which was the first approach and flyaround of the Russian Space Station Mir by the Space Shuttle. Collins and six other crew members will depart shortly for Launch Pad 39A, where the Space Shuttle Atlantis awaits liftoff during an approximate 7-minute launch window which opens at about 4:08 a.m. This will be the sixth docking of the Space Shuttle with the Mir. The exact liftoff time will be determined about 90 minutes prior to launch, based on the most current location of Mir.

    The charged particle spectrum for nuclei from protons to neon, (charge Z = 10) was observed during the cruise phase and orbit around Mars by the MARIE charged particle spectrometer on the Odyssey spacecraft. The cruise data were taken between April 23, 2001 and mid-August 2001. The Mars orbit data were taken March 5, 2002 through May 2002 and are scheduled to continue until August 2004. Charge peaks are clearly separated for charges up to Z = 10. Especially prominent are the carbon and oxygen peaks, with boron and nitrogen also clearly visible. Although heavy ions are much less abundant than protons in the cosmic ray environment, it is important to determine their abundances because their ionization energy losses (proportional to Z2) are far more dangerous to humans and to instruments. Thus the higher charged nuclei make a significant contribution to dose and dose equivalent received in space. Results of the charged particle spectrum measurements will be reported.

    On September 2013 an attack on the Westgate mall in Kenya led to a four day siege, resulting in 67 fatalities and 175 wounded. During the crisis, Twitter became a crucial channel of communication between the government, emergency responders and the public, facilitating the emergency management of the event. The objectives of this paper are to present the main activities, use patterns and lessons learned from the use of the social media in the crisis. Using TwitterMate, a system developed to collect, store and analyze tweets, the main hashtags generated by the crowd and specific Twitter accounts of individuals, emergency responders and NGOs, were followed throughout the four day siege. A total of 67,849 tweets were collected and analyzed. Four main categories of hashtags were identified: geographical locations, terror attack, social support and organizations. The abundance of Twitter accounts providing official information made it difficult to synchronize and follow the flow of information. Many organizations posted simultaneously, by their manager and by the organization itself. Creating situational awareness was facilitated by information tweeted by the public. Threat assessment was updated through the information posted on social media. Security breaches led to the relay of sensitive data. At times, misinformation was only corrected after two days. Social media offer an accessible, widely available means for a bi-directional flow of information between the public and the authorities. In the crisis, all emergency responders used and leveraged social media networks for communicating both with the public and among themselves. A standard operating procedure should be developed to enable multiple responders to monitor, synchronize and integrate their social media feeds during emergencies. This will lead to better utilization and optimization of social media resources during crises, providing clear guidelines for communications and a hierarchy for dispersing

    We performed whole exome sequencing on a patient with Charcot-Marie-Tooth disease type 1 and identified a de novo mutation in PMP2, the gene that encodes the myelin P2 protein. This mutation (p.Ile52Thr) was passed from the proband to his one affected son, and segregates with clinical and electrophysiological evidence of demyelinating neuropathy. We then screened a cohort of 136 European probands with uncharacterized genetic cause of Charcot-Marie-Tooth disease and identified another family with Charcot-Marie-Tooth disease type 1 that has a mutation affecting an adjacent amino acid (p.Thr51Pro), which segregates with disease. Our genetic and clinical findings in these kindred demonstrate that dominant PMP2 mutations cause Charcot-Marie-Tooth disease type 1.

    Recent work in the central Andean Main Range of Chile near Laguna del Laja (˜37.5°S, 71°W) has produced the first mammal fossils for the region. Fossils, locally abundant and well preserved, occur patchily across a wide area southeast of the lake. Mammalian remains are derived from generally strongly folded (kilometer-scale) exposures of the locally ˜1.8 km thick, early to middle Miocene Cura-Mallín Formation; two identifiable specimens have been recovered from the overlying Trapa Trapa Formation as well. Both formations consist primarily of well-stratified (1-5 m thick layers) volcaniclastic and volcanic strata, deposited predominantly in fluviatile systems. The Cura-Mallín Formation is possibly the southern continuation of (or lateral equivalent to) the richly fossiliferous Abanico Formation mapped between ˜32°S and 36°S. Intensive sampling in a series of localities east and south of Laguna del Laja has yielded diverse faunas, in addition to radioisotopically dateable horizons. The new fossil mammal faunas represent as many as six South American Land Mammal "Ages" (SALMAs). Fossils, together with preliminary 40Ar/ 39Ar radioisotopic dates, ranging from ˜9 to 20 Ma across the exposed thickness of the Cura-Mallín Formation and into the overlying Trapa Trapa Formation, provide a robust geochronological framework for middle Cenozoic strata in the Laguna del Laja region. The sequence of directly superposed mammalian assemblages at Laguna del Laja is one of the longest in all of South America, rivaled only by the classic Gran Barranca section of Patagonian Argentina. These data illuminate the geological history of the area and its record of mammalian evolution. The potential to isotopically date these diverse faunas with high precision (error ± 0.5 Ma) presents a rare opportunity to calibrate related portions of the SALMA sequence.

    In order to assess indoor air quality (IAQ), two 1-week monitoring campaigns of volatile organic compounds (VOC) were performed in different areas of a multistorey shopping mall. High-spatial-resolution monitoring was conducted at 32 indoor sites located in two storehouses and in different departments of a supermarket. At the same time, VOC concentrations were monitored in the mall and parking lot area as well as outdoors. VOC were sampled at 48-h periods using diffusive samplers suitable for thermal desorption. The samples were then analyzed with gas chromatography-mass spectrometry (GC-MS). The data analysis and chromatic maps indicated that the two storehouses had the highest VOC concentrations consisting principally of terpenes. These higher TVOC concentrations could be a result of the low efficiency of the air exchange and intake systems, as well as the large quantity of articles stored in these small spaces. Instead, inside the supermarket, the food department was the most critical area for VOC concentrations. To identify potential emission sources in this department, a continuous VOC analyzer was used. The findings indicated that the highest total VOC concentrations were present during cleaning activities and that these activities were carried out frequently in the food department. The study highlights the importance of conducting both high-spatial-resolution monitoring and high-temporal-resolution monitoring. The former was able to identify critical issues in environments with a complex emission scenario while the latter was useful in interpreting the dynamics of each emission source.

    2014-03-01

    Charcot-Marie-Tooth (CMT) disease is a clinically and genetically heterogeneous group of diseases with over 45 different causative gene mutations identified. Nerve conduction studies are important for the classification and diagnosis of CMT, whereas ultrasound (US) is increasingly used to assess the peripheral nerves of patients with CMT, as a complement to neurophysiological studies. Recent ultrasound assessment reports of peripheral nerves in CMT are summarized here. An ultrasound finding of CMT1A, which is the most common demyelinating subtype of CMT, is characterized by uniform enlargement of peripheral nerves and nerve roots. Patients with CMT1B (MPZ mutation) also have larger nerves than normal subjects do. Peripheral nerves of patients with CMT2, which is an axonal type of CMT, are slightly larger than those of normal subjects. Focal enlargement of nerves at entrapment sites is a characteristic US finding of hereditary neuropathy with liability to pressure palsy. US findings of CMT are thus subtype-specific. Therefore, the assessment of nerve US may become a useful supporting tool for the diagnosis of CMT subtypes.

  17. Princess Marie Bonaparte, Edgar Allan Poe, and psychobiography.

    PubMed

    Warner, S L

    1991-01-01

    Princess Marie Bonaparte was a colorful yet mysterious member of Freud's inner circle of psychoanalysis. In analysis with Freud beginning in 1925 (she was then 45 years old), she became a lay analyst and writer of many papers and books. Her most ambitious task was a 700-page psychobiography of Edgar Allan Poe that was first published in French in 1933. She was fascinated by Poe's gothic stories--with the return to life of dead persons and the eerie, unexpected turns of events. Her fascination with Poe can be traced to the similarity of their early traumatic life experiences. Bonaparte had lost her mother a month after her birth. Poe's father deserted the family when Edgar was two years old, and his mother died of tuberculosis when he was three. Poe's stories helped him to accommodate to these early traumatic losses. Bonaparte vicariously shared in Poe's loss and the fantasies of the return of the deceased parent in his stories. She was sensitive and empathetic to Poe's inner world because her inner world was similar. The result of this psychological fit between Poe and Bonaparte was her psychobiography, The Life and Works of Edgar Allan Poe. It was a milestone in psychobiography but limited in its psychological scope by its strong emphasis on early childhood trauma. Nevertheless it proved Bonaparte a bona fide creative psychoanalyst and not a dilettante propped up by her friendship with Freud.

    Charcot-Marie-Tooth disease (CMT) is a slowly progressive hereditary degenerative disease and one of the most common neuromuscular disorders. Exercise may be beneficial to maintain strength and function for people with CMT, however, no comprehensive evaluation of the benefits and risks of exercise have been conducted. A systematic review was completed searching numerous electronic databases from earliest records to February 2015. Studies of any design including participants of any age with confirmed diagnosis of CMT that investigated the effects of exercise were eligible for inclusion. Of 13,301 articles identified following removal of duplicates, 11 articles including 9 unique studies met the criteria. Methodological quality of studies was moderate, sample sizes were small, and interventions and outcome measures used varied widely. Although the majority of the studies identified changes in one or more outcome measurements across exercise modalities, the majority were non-significant, possibly due to Type II errors. Significant effects described included improvements in strength, functional activities, and physiological adaptations following exercise. Despite many studies showing changes in strength and function following exercise, findings of this review should be met with caution due to the few studies available and moderate quality of evidence. Well-powered studies, harmonisation of outcome measures, and clearly described interventions across studies would improve the quality and comparability of the evidence base. The optimal exercise modality and intensity for people with CMT as well as the long-term safety of exercise remain unclear.

  19. The shifting paradigm of Charcot-Marie-Tooth disease.

    Molecular studies have created a paradigm shift in our perception of Charcot-Marie-Tooth disease (CMT). Indeed, CMT has evolved from the concept of a rather homogeneous hereditary disease exclusively involving peripheral nerves to the concept of a highly heterogeneous clinical and genetic syndrome mainly - but sometimes not exclusively - involving the peripheral nervous system. The phenotypic spectrum of CMT overlaps with other inherited neuropathies such as distal hereditary motor neuropathy (dHMN), hereditary sensory and autonomic neuropathy (HSAN), spinal muscular atrophy (SMA) subtypes, and the neuropathies of mitochondrial disorders. At a molecular level, mutations in one given gene may alternatively provoke CMT, HSAN, dHMN or SMA variants. Over the last years, there have been dramatic advances in deciphering the molecular basis for many CMT subtypes and more than 900 different mutations in more than 60 causative genes are now described. However, as 75% of CMT causative genes apparently remain unknown and as disease-specific therapies are not available, major advances are yet to come in the field of CMT.

    Mutations of genes whose primary function is the regulation of membrane traffic are increasingly being identified as the underlying causes of various important human disorders. Intriguingly, mutations in ubiquitously expressed membrane traffic genes often lead to cell type- or organ-specific disorders. This is particularly true for neuronal diseases, identifying the nervous system as the most sensitive tissue to alterations of membrane traffic. Charcot-Marie-Tooth (CMT) disease is one of the most common inherited peripheral neuropathies. It is also known as hereditary motor and sensory neuropathy (HMSN), which comprises a group of disorders specifically affecting peripheral nerves. This peripheral neuropathy, highly heterogeneous both clinically and genetically, is characterized by a slowly progressive degeneration of the muscle of the foot, lower leg, hand and forearm, accompanied by sensory loss in the toes, fingers and limbs. More than 30 genes have been identified as targets of mutations that cause CMT neuropathy. A number of these genes encode proteins directly or indirectly involved in the regulation of intracellular traffic. Indeed, the list of genes linked to CMT disease includes genes important for vesicle formation, phosphoinositide metabolism, lysosomal degradation, mitochondrial fission and fusion, and also genes encoding endosomal and cytoskeletal proteins. This review focuses on the link between intracellular transport and CMT disease, highlighting the molecular mechanisms that underlie the different forms of this peripheral neuropathy and discussing the pathophysiological impact of membrane transport genetic defects as well as possible future ways to counteract these defects.

    Marie Sklodowska-Curie, an extraordinary woman, a Polish scientist who lived and worked in France, led to the development of nuclear energy and the treatment of cancer. She was the laureate of two Nobel Prizes, the first woman in Europe who obtained the degree of Doctor of Science and opened the way for women to enter fields which had been previously reserved for men only. As a result of her determination and her love of freedom, she has become an icon for many female scientists active in radiation sciences. They are successors of Maria Curie and without the results of their work, improvement in radiation oncology will not be possible. Many of them shared some elements of Maria Curie's biography, like high ethical and moral standards, passionate dedication to work, strong family values, and scientific collaboration with their husbands. The significance of Tikvah Alper, Alma Howard, Shirley Hornsey, Juliana Denekamp, Helen Evans, Eleanor Blakely, Elizabeth L. Travis, Fiona Stewart, Andree Dutreix, Catharine West, Peggy Olive, Ingela Turesson, Penny Jeggo, Irena Szumiel, Eleonor Blakely, Sara Rockwell and Carmel Mothersill contribution to radiation oncology is presented. All the above mentioned ladies made significant contribution to the development of radiotherapy (RT) and more efficient cancer treatment. Due to their studies, new schedules of RT and new types of ionizing radiation have been applied, lowering the incidence of normal tissue toxicity. Their achievements herald a future of personalized medicine. PMID:27601958

    The 50th anniversary of Mary Lyon's 1961 Nature paper, proposing random inactivation in early embryonic life of one of the two X chromosomes in the cells of mammalian females, provides an opportunity to remember and celebrate the work of those involved. While the hypothesis was initially put forward by Lyon based on findings in the mouse, it was founded on earlier studies, notably the work of Susumu Ohno; it was also suggested independently by Beutler and colleagues using experimental evidence from a human X-linked disorder, glucose-6-phosphate dehydrogenase deficiency, and has proved to be of as great importance for human and medical genetics as it has for general mammalian genetics. Alongside the hypothesis itself, previous cytological studies of mouse and human chromosomes, and the observations on X-linked mutants in both species deserve recognition for their essential role in underpinning the hypothesis of random X-inactivation, while subsequent research on the X-inactivation centre and the molecular mechanisms underlying the inactivation process represent some of the most outstanding contributions to human and wider mammalian genetics over the past 50 years.

  3. "Typhoid Mary" and "HIV Jane": responsibility, agency and disease prevention.

    The construction of disease risks as knowable, calculable and preventable in dominant social science and public health discourses has fostered a certain kind of logic about individual risk and the responsibility for infection. Disease control measures that have developed out of this logic typically fail to recognise the socio-structural roots of many high-risk behaviours that are linked to the spread of infection. Instead, they hold the disease carrier responsible for managing his/her own risk of infection of others, and rely on constraining the agency of the carrier (e.g. by constraining movement, contact or occupation). In occupations associated with a high risk of infection, the idea of responsibility of the actor implicitly raises issues of "professional responsibility". Using the case of "Typhoid Mary" and a hypothetical case of "HIV Jane", this paper explores some of the problems with making sex workers responsible for the prevention of HIV transmission. It argues that for the notion of "responsibility" to make any sense, the HIV-positive person must be in a position to exercise responsibility, and for this they must have agency.

    2015-01-01

    Hereditary motor and sensory neuropathies, especially Charcot-Marie-Tooth disease, are frequently expressed with an acquired cavusvarus foot which is characterized by a fixed increase of the plantar arch and hindfoot inversion. Diagnosis of the underlying condition achieved through careful patient assessment and local evaluations is the keystone for decision-making about the adequate treatment. The cavus may present as an isolated deformity of the forefoot, hindfoot or it may be a combination of both locations. Related deformities, mainly the varus and toe clawing require appropriate evaluation; clinical characteristics such as severity of the deformity, impairment of the muscular power, flexibility and patient's age are important characteristics in the treatment decision. Conservative treatment of the cavusvarus foot with physiotherapy, insoles and shoe modifications are reserved to young patients and mild deformities. However, there is a tendency of the deformity to become more severe over time because of the progressive feature of the underlying neurological condition. So, the surgical treatment by using classical techniques is performed in early stages. Most importantly is the identification of the primary and main components of each deformity to properly correct them, if possible. Muscular transfers are used to treat the dynamic unbalance, retracted structures should be either divided or lengthened and localized osteotomies should be preferred over arthrodeses, which are reserved for stiff and severely deformed feet in adults.

    Background Charcot Marie Tooth disease (CMT) affects one in 2500 people and is caused by mutations in more than 30 genes. Identifying the genetic cause of CMT is often necessary for family planning, natural history studies and for entry into clinical trials. However genetic testing can be both expensive and confusing to patients and physicians. Methods We analyzed data from 1024 of our patients to determine the percentage and features of each CMT subtype within this clinic population. We identified distinguishing clinical and physiological features of the subtypes that could be used to direct genetic testing for patients with CMT. Findings Of 1024 patients evaluated, 787 received CMT diagnoses. Five hundred twenty-seven patients with CMT (67%) received a genetic subtype, while 260 did not have a mutation identified. The most common CMT subtypes were CMT1A, CMT1X, HNPP, CMT1B, and CMT2A. All other subtypes accounted for less than 1% each. Eleven patients had more than one genetically identified subtype of CMT. Patients with genetically identified CMT were separable into specific groups based on age of onset and the degree of slowing of motor nerve conduction velocities. Interpretation Combining features of the phenotypic and physiology groups allowed us to identify patients who were highly likely to have specific subtypes of CMT. Based on these results, we propose a strategy of focused genetic testing for CMT illustrated in a series of flow diagrams created as testing guides. PMID:21280073

    In order to determine the optimal approach for mutation testing in the form of Charcot-Marie-Tooth (CMT) neuropathy, consecutive patients with a CMT phenotype, available family history information on at least first-degree relatives, and median motor conduction velocities of less than 50 m/sec were tested for the CMT1A duplication and for connexin32, peripheral myelin protein 22 (PMP22) and myelin protein zero (P0) point mutations. A cutoff value for median motor conduction velocity of less than 50 m/sec was adopted to include all CMTX families. All of the connexin32 mutations, except for one sporadic case, were found by first selecting families with no male-to-male inheritance of CMT and neurophysiological indicators of CMTX. All PMP22 and P0 mutations were found by selecting Dejerine-Sottas cases or dominantly inherited CMT1 with a very severe phenotype. It is concluded that "blind" testing of CMT1 families for connexin32, P0, and PMP22 mutations is of limited value. PMID:10586262

  10. M-Ary Alpha-Stable Noise Modulation in Spread-Spectrum Communication

    NASA Astrophysics Data System (ADS)

    Cek, Mehmet Emre

    2015-04-01

    In this paper, a spread-spectrum communication system based on a random carrier is proposed which transmits M-ary information. The random signal is considered as a single realization of a random process taken from prescribed symmetric α-stable (SαS) distribution that carries digital M-ary information to be transmitted. Considering the noise model in the channel as additive white Gaussian noise (AWGN), the transmitter sends the information carrying random signal from non-Gaussian density. Alpha-stable distribution is used to encode the M-ary message. Inspired by the chaos shift keying techniques, the proposed method is called M-ary symmetric alpha-stable differential shift keying (M-ary SαS-DSK). The main purpose of preferring non-Gaussian noise instead of conventional pseudo-noise (PN) sequence is to overcome the drawback of self-repeating noise-like sequences which are detectable due to the periodic behavior of the autocorrelation function of PN sequences. Having infinite second order moment in α-stable random carrier offers secrecy of the information due to the non-constant autocorrelation behavior. The bit error rate (BER) performance of the proposed method is illustrated by Monte Carlo simulations with respect to various characteristic exponent values and different data length.

    Ascension Health has asked all of its health care ministries to promote spirituality in the workplace. St. Mary's Health System, Evansville, IN, responded to this request with several initiatives, including the development, facilitation, and implementation of a new model for what St. Mary's calls its "Employee Renewal Day." Revamped from a voluntary unpaid day to a paid day on which participation is strongly encouraged, Employee Renewal Day 2004 focused on fellowship, relaxation, and the history and heritage of St. Mary's and its sponsor. Based on an employee's suggestion, the mission team adopted a nautical theme, "Sailabration Cruise: A Day of Renewal," and took employees on "a voyage" complete with mission-themed ports, passenger photos, a ship's log, purser's desk, and an activities director. More than 1,200 St. Mary's employees-or 23 percent of the total workforce-participated. All of St. Mary's 135 leaders were in attendance. The new Employee Renewal Day model will be tried over a three-year period, so as to measure the progress of furthering the integration of spirituality within the organizational culture.

    Marie Curie Cancer Care established its nursing service in 1958; however, the service has had little formal evaluation. This study aimed to describe and evaluate the care provided by Marie Curie nurse, and in particular to determine whether patients in their care remained and died at home. Two existing data sets were used: data on all patients referred to the Marie Curie Nursing Services in 147 areas of England, Wales, Scotland and Northern Ireland for 26 months, and data on cancer death registrations in England. A request for a Marie Curie nurse was made for 26,632 patients, 97% of whom had cancer and 11% of whom lived alone. The amount of care provided varied enormously (<1 hour-2862 hours), although the vast majority of patients less than 300 hours of nursing care. Place of death was recorded for only half these patients; 94% died at home, 2.5% in a hospice, 2.3% in a hospital, 0.2% in a nursing home and 0.6% other. Home death was most often associated with patients receiving medication via a syringe driver, patients living with other people, patients with cancer, other than prostate cancer, shorter time between referral and death and younger age. The results lend support to the theory that the care given to patients in their homes by Marie Curie nurses facilitated home death for many patients. Services need to ensure that mechanisms are in place to achieve data collection. Rigorous prospective evaluation is needed in the future.

    Charcot-Marie-Tooth disease (CMT) (ORPHA166) is the most frequent hereditary neuropathy. CMT is a heterogeneous group of disorders which, despite some variability in their clinical features, share the same general phenotype, usually characterized by wasting and weakness of distal limb muscles, decreased to absent deep tendon reflexes, distal sensory loss, and frequent skeletal deformities. Despite the clinical and molecular description of this disease in the last 20 years, there is no effective drug or advanced therapy available. Here we have pretend the identification of metabolic and oxidative stress biomarkers in plasmas from patients with duplication at PMP22 gene, the most frequent mutation causing CMT, and clinically characterized as CMT1A. The samples were collected in the neuropathy units from "La Fe" Hospital of Valencia, "Bellvitge" Hospital of Barcelona, "La Paz" Hospital of Madrid, and "Virgen del Rocío" Hospital of Sevilla. The metabolic biomarkers research was performed using 2D-DIGE analysis (Typhoon TRIO, GE) and DeCyder software (GE). Protein identification was made by mass spectrometry by MALDI-TOF-TOF (ABSciex) and liquid Chromatography analysis (ABSciex). The oxidative stress biomarkers research consisted in carbonylated proteins analysis by reaction with DNPH and Dot-blot. Total antioxidant capacity and GSSG/GSH ratio were analyzed with Antioxidant Assay kit (Cayman) and Glutathione Fluorescent detection Kit (Arbor Assays), respectively. Finally now we are performing the MDA levels by HPLC-UV. We found 8, 13 and 36 proteins with differential expression in mild, moderate and severely affected patients, respectively compared with their own matched controls. Also we found differences on oxidative stress parameters between de different groups analyzed. Our results suggest differences in the oxidative stress profile between the studied phenotypes in CMT1A patients.

    Objective Preimplantation genetic diagnosis (PGD) is an assisted reproductive technique for couples carrying genetic risks. Charcot-Marie-Tooth (CMT) disease is the most common hereditary neuropathy, with a prevalence rate of 1/2,500. In this study, we report on our experience with PGD cycles performed for CMT types 1A and 2F. Methods Before clinical PGD, we assessed the amplification rate and allele drop-out (ADO) rate of multiplex fluorescent polymerase chain reaction (PCR) followed by fragment analysis or sequencing using single lymphocytes. We performed six cycles of PGD for CMT1A and one cycle for CMT2F. Results Two duplex and two triplex protocols were developed according to the available markers for each CMT1A couple. Depending on the PCR protocols, the amplification rates and ADO rates ranged from 90.0% to 98.3% and 0.0% to 11.1%, respectively. For CMT2F, the amplification rates and ADO rates were 93.3% and 4.8%, respectively. In case of CMT1A, 60 out of 63 embryos (95.2%) were diagnosed and 13 out of 21 unaffected embryos were transferred in five cycles. Two pregnancies were achieved and three babies were delivered without any complications. In the case of CMT2F, a total of eight embryos were analyzed and diagnosed. Seven embryos were diagnosed as unaffected and four embryos were transferred, resulting in a twin pregnancy. Two healthy babies were delivered. Conclusion This is the first report of successful pregnancy and delivery after specific PGD for CMT disease in Korea. Our PGD procedure could provide healthy babies to couples with a high risk of transmitting genetic diseases. PMID:24505562

    The Lake Mary quadrangle is in eastern Iron County, in the west part of the Upper Peninsula of Michigan. The quadrangle is underlain by Lower and Middle Precambrian rocks, formerly designated Archean and Algonkian rocks, and is extensively covered by Pleistocene glacial deposits. A few Upper Precambrian (Keweenawan) diabase dikes and two remnants of sandstone and dolomite of early Paleozoic age are also found in the area. The major structural feature is the Holmes Lake anticline, the axis of which strikes northwest through the northeast part of the quadrangle. Most of the quadrangle, therefore, is underlain by rock of the west limb of the anticline. To the northwest along the fold axis, the Holmes Lake anticline is separated from the Amasa oval by a saddle of transverse folds in the vicinity of Michigamme Mountain in the Kiernan quadrangle. The Lower Precambrian rocks are represented by the Dickinson group and by porphyritic red granite whose relation to the Dickinson group is uncertain, but which may be older. The rocks of the Dickinson group are chiefly green to black metavolcanic schist and red felsite, some of the latter metarhyolite. The dark schist is commonly magnetic. The Dickinson group underlies the core area of the Holmes Lake anticline, which is flanked by steeply dipping Middle Precambrian formations of the Animikie series. A major unconformity separates the Lower Precambrian rocks from the overlying Middle Precambrian rocks. In ascending order the formations of the Middle Precambrian are the Randville dolomite, the Hemlock formation, which includes the Mansfield iron-bearing slate member, and the Michigamme slate. An unconformity occurs between the Hemlock formation and Michigamme slate. The post-Hemlock unconformity is thought to be represented in the Lake Mary quadrangle by the absence of iron-formation of the Amasa formation, which is known to lie between the Hemlock and the Michigamme to the northwest of the Lake Mary quadrangle in the Crystal

  16. Evaluating Marie Byrd Land stability using an improved basal topography

    2014-12-01

    Prior understanding of the ice-sheet setting in Marie Byrd Land (MBL) was derived primarily from geologic and geochemical studies of the current nunataks, with very few geophysical surveys imaging the ice covered regions. The geologic context suggested that the ice rests on a broad regional high, in contrast to the deep basins and trenches that characterize the majority of West Antarctica. This assumed topography would favor long-term stability for the West Antarctic Ice Sheet (WAIS) in MBL. Airborne geophysical data collected in 2009 reveal a much deeper bed than previously estimated, including a significant trough underlying DeVicq Glacier and evidence for extensive glacial erosion. Using these data, we produce a new map of subglacial topography, with which we model the sensitivity of WAIS to a warming ocean using the ice-sheet model of Pollard and DeConto (2012b). We compare the results to estimates of ice loss during WAIS collapse using the previously defined subglacial topography, to determine the impact of the newly discovered subglacial features. Our results indicate that the topographic changes are not sufficient to destabilize the northern margin of MBL currently feeding the Getz Ice Shelf; the majority of ice loss occurs from flow toward the Siple Coast. However, despite only slight dynamic differences, using the new bed as a boundary condition results in an additional 8 cm of sea-level rise during major glacial retreat, an increase of just over 2%. Precise estimation of past and future ice retreat, as well as a complete understanding of the geologic history of the region, will require a higher resolution picture of the bed topography around the Executive Committee mountains.

    KENNEDY SPACE CENTER, FLA. -- STS-84 Pilot Eileen M. Collins prepares to enter the Space Shuttle Atlantis at Launch Pad 39A with help from white room closeout crew members. The fourth Shuttle mission of 1997 will be the sixth docking of the Space Shuttle with the Russian Space Station Mir. The commander is Charles J. Precourt. The pilot is Eileen Marie Collins. The five mission specialists are C. Michael Foale, Carlos I. Noriega, Edward Tsang Lu, Jean-Francois Clervoy of the European Space Agency and Elena V. Kondakova of the Russian Space Agency. The planned nine-day mission will include the exchange of Foale for U.S. astronaut and Mir 23 crew member Jerry M. Linenger, who has been on Mir since Jan. 15. Linenger transferred to Mir during the last docking mission, STS-81; he will return to Earth on Atlantis. Foale is slated to remain on Mir for about four months until he is replaced in September by STS-86 Mission Specialist Wendy B. Lawrence. During the five days Atlantis is scheduled to be docked with the Mir, the STS-84 crew and the Mir 23 crew, including two Russian cosmonauts, Commander Vasily Tsibliev and Flight Engineer Alexander Lazutkin, will participate in joint experiments. The STS-84 mission also will involve the transfer of more than 7,300 pounds of water, logistics and science equipment to and from the Mir. Atlantis is carrying a nearly 300-pound oxygen generator to replace one of two Mir units which have experienced malfunctions. The oxygen it generates is used for breathing by the Mir crew.

    A protease-producing marine bacterium, designated CF12-14(T), was isolated from sediment of the South China Sea. Phylogenetic analysis of the 16S rRNA gene sequence revealed that strain CF12-14(T) formed a separate lineage within the genus Idiomarina (Gammaproteobacteria). The isolate showed the highest 16S rRNA gene sequence similarity with Idiomarina salinarum ISL-52(T) (94.7 %), Idiomarina seosinensis CL-SP19(T) (94.6 %) and other members of the genus Idiomarina (91.9-94.6 %). Cells were gram-negative, aerobic, flagellated, straight or slightly curved, and often formed buds and prosthecae. Strain CF12-14(T) grew at 4-42 °C (optimum 30-35 °C) and with 0.1-15 % (w/v) NaCl (optimum 2-3 %). The isolate reduced nitrate to nitrite and hydrolysed DNA, but did not produce acids from sugars. The predominant cellular fatty acids were iso-C(15 : 0) (27.4 %), iso-C(17 : 0) (16.0 %) and iso-C(17 : 1)ω9c (15.8 %). The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. The major respiratory quinone was ubiquinone 8. The DNA G+C content was 50.4 mol%. The phylogenetic, phenotypic and chemotaxonomic data supported the conclusion that CF12-14(T) represents a novel species of the genus Idiomarina, for which the name Idiomarina maris sp. nov. is proposed. The type strain is CF12-14(T) ( = CCTCC AB 208166(T) = KACC 13974(T)).

  20. MARIE: Current Status and Results from 20 Months of Observations at Mars

    The MARIE instrument aboard the 2001 Mars Odyssey spacecraft detects energetic charged particles in the Galactic Cosmic Radiation (GCR) and during solar particle events (SPE) [1]. As of this writing (January 2004), MARIE has been turned off, after losing communication with the spacecraft during the large SPE of October 28, 2003. However, during the prior 20 months, MARIE collected data almost continuously, observing several solar events and the nearly-constant GCR. There is still a possibility the instrument can be recovered, and troubleshooting efforts are scheduled to begin in May 2004, following the completion of the primary missions of MER-A (Spirit) and MER-B (Opportunity). At present, Odyssey is acting as a telecommunications relay for the rovers and only routine science operations are permitted in this mode.

    2014-11-01

    Mutations in VCP have been reported to account for a spectrum of phenotypes that include inclusion body myopathy with Paget's disease of the bone and frontotemporal dementia, hereditary spastic paraplegia, and 1-2% of familial amyotrophic lateral sclerosis. We identified a novel VCP mutation (p.Glu185Lys) segregating in an autosomal dominant Charcot-Marie-Tooth disease type 2 family. Functional studies showed that the Glu185Lys variant impaired autophagic function leading to the accumulation of immature autophagosomes. VCP mutations should thus be considered for genetically undefined Charcot-Marie-Tooth disease type 2.

    PubMed

    Kirshtein, Boris; Meirovitz, Mihai; Okon, Elimelech; Piura, Benjamin

    2006-01-01

    Umbilical metastasis (Sister Mary Joseph's nodule) is often the first sign of intraabdominal and/or pelvic carcinoma. We describe the fourth case reported in the literature of Sister Mary Joseph's nodule originating from fallopian tube carcinoma. In a 54-year-old woman, Sister Mary Joseph's nodule was unexpectedly detected during umbilical hernia repair. Subsequent laparoscopy revealed a 2-cm friable tumor located at the fimbriated end of right fallopian tube and 1-cm peritoneal implant in the pouch of Douglas. Laparoscopic bilateral adnexectomy and resection of the peritoneal implant were performed. Because frozen section examination revealed fallopian tube carcinoma, the procedure was continued with laparotomy including total abdominal hysterectomy, omentectomy, and pelvic lymph node sampling. Final diagnosis was stage IIIB fallopian tube carcinoma. The patient received postoperative adjuvant chemotherapy with single-agent carboplatin and has remained alive and with no evidence of disease. It is concluded that in cases of Sister Mary Joseph's nodule, laparoscopy can be a useful tool in the search of the primary tumor in the abdomen and/or pelvis. Laparoscopy can provide crucial information with respect to the location, size, and feasibility of optimal surgical resection of the intraabdominal and/or pelvic tumors.

    The deglaciation history of West Antarctica provides a long-term record of West Antarctic ice sheet dynamics on timescales that are difficult to address observationally or by modeling. By dating moraine deposits stranded on mountain flanks as the ice sheet thinned, we are reconstructing the deglaciation history of a 70 km transect along the Boyd Glacier, in the Ford Ranges, Marie Byrd Land. Fresh erratics and abraded bedrock extend to summit level on most nunataks, indicating that these were overrun by ice during the last glaciation. Conversely, high summits near the coast are more intensely weathered than lower-lying peaks, and one erratic from this weathered zone gives a cosmogenic Be-10 exposure age of 103 ka, suggesting (though it does not prove) that these peaks stood above the surface of the glacial maximum ice sheet. If so, the age of an erratic immediately below the weathering boundary, 10.4 +/- 0.7 ka, dates the glacial maximum in the Ford Ranges. All other erratics, from glaciated surfaces at lower elevation, give younger exposure ages. Summit erratics from Mt Blades, Mt Passel and an unnamed nunatak in the eastern Fosdick Mtns indicate that these peaks emerged from the ice sheet at 6.8 +/- 0.5 ka, 3.6 +/- 0.3 ka, and 4.7 +/- 0.4 ka, respectively. Subsequent downwasting rates, inferred from the decrease in exposure ages with elevation on these mountains, were between 5 and 10 cm per year. The youngest age obtained so far, 590 +/- 70 years, comes from an erratic on the lower slopes of Mt Rea, 100-150 m above the Arthur and Boyd Glaciers. From these results we can draw the following conclusions about West Antarctic Ice Sheet (WAIS) deglaciation in the Ford Ranges: (i) Most thinning of the WAIS took place in the late Holocene. (ii) Therefore, recession post-dated climatic warming, which Antarctic ice cores indicate commenced at 20 ka, by 10-15 kyr. (iii) Recession post-dated all but the final stages of global eustatic sea level rise. The ice sheet grounding

    Charcot-Marie-Tooth disease (CMT) is a complex disorder with wide genetic heterogeneity. Here we present a new axonal Charcot-Marie-Tooth disease form, associated with the gene microrchidia family CW-type zinc finger 2 (MORC2). Whole-exome sequencing in a family with autosomal dominant segregation identified the novel MORC2 p.R190W change in four patients. Further mutational screening in our axonal Charcot-Marie-Tooth disease clinical series detected two additional sporadic cases, one patient who also carried the same MORC2 p.R190W mutation and another patient that harboured a MORC2 p.S25L mutation. Genetic and in silico studies strongly supported the pathogenicity of these sequence variants. The phenotype was variable and included patients with congenital or infantile onset, as well as others whose symptoms started in the second decade. The patients with early onset developed a spinal muscular atrophy-like picture, whereas in the later onset cases, the initial symptoms were cramps, distal weakness and sensory impairment. Weakness and atrophy progressed in a random and asymmetric fashion and involved limb girdle muscles, leading to a severe incapacity in adulthood. Sensory loss was always prominent and proportional to disease severity. Electrophysiological studies were consistent with an asymmetric axonal motor and sensory neuropathy, while fasciculations and myokymia were recorded rather frequently by needle electromyography. Sural nerve biopsy revealed pronounced multifocal depletion of myelinated fibres with some regenerative clusters and occasional small onion bulbs. Morc2 is expressed in both axons and Schwann cells of mouse peripheral nerve. Different roles in biological processes have been described for MORC2. As the silencing of Charcot-Marie-Tooth disease genes have been associated with DNA damage response, it is tempting to speculate that a deregulation of this pathway may be linked to the axonal degeneration observed in MORC2 neuropathy, thus adding a

    Communicating archaeological findings to non-archaeologists is one of the most important and challenging aspects of the discipline. Archaeologists must serve multiple publics, bring communities into the archaeological process, and effectively disseminate information in order for their work to achieve relevance in the modern world. Communication with the public can take many forms, and brings together aspects of historic preservation, dialogic interpretation, applied critical archaeology, heritage, and landscape studies. This dissertation analyzes public interpretation at St. Mary's City, Maryland, a multi-component historic landscape containing historic and prehistoric sites from various time periods and proposes measures to be taken there to better engage the public. This site presents a unique context for public interpretation: the Historic St. Mary's City archaeological museum occupies a portion of the landscape, while neighboring St. Mary's College of Maryland is a public collegiate campus that contains an imposing number of uninterpreted sites. Exploration of the histories and relationships between these institutions provide insight into the many factors which impact public interpretation. Examination of this case includes identifying audiences, gauging attitudes towards archaeology, assessing current interpretive measures, and identifying areas where public engagement can be improved. The example of St. Mary's outlines how an individual's relationship to archaeology is interwoven into their experience of the landscape. The past and present coexist on historic landscapes, and public communication can use this juxtaposition to engage audiences in meaningful ways. I conclude by developing an archaeological walking tour of the St. Mary's landscape aimed at creating discussion and making people aware of the sites around them.

  19. Spatially detailed quantification of metal loading for decision making: Metal mass loading to American fork and Mary Ellen Gulch, Utah

    Effective remediation requires an understanding of the relative contributions of metals from all sources in a catchment, and that understanding must be based on a spatially detailed quantification of metal loading. A traditional approach to quantifying metal loading has been to measure discharge and chemistry at a catchment outlet. This approach can quantify annual loading and the temporal changes in load, but does not provide the needed spatial detail to evaluate specific sources, which is needed to support remediation decisions. A catchment or massloading approach provides spatial detail by combining tracer-injection and synoptic-sampling methods to quantify loading. Examples of studies in American Fork, Utah, and its tributary Mary Ellen Gulch illustrate this different approach. The mass-loading study in American Fork treated Mary Ellen Gulch as a single inflow. From that point of view, Mary Ellen Gulch was one of the greatest sources of Fe, Mn, Zn, and colloidal Pb loads to American Fork. But when Mary Ellen Gulch was evaluated in a separate catchment study, the detailed locations of metal loading were identified, and the extent of metal attenuation upstream from the mouth of Mary Ellen Gulch was quantified. The net, instantaneous load measured at the mouth of Mary Ellen Gulch for remediation planning would greatly underestimate the contributions of principal sources within the catchment. Extending the detailed sampling downstream from Mary Ellen Gulch indicated the possibility of diffuse groundwater inflow from Mary Ellen Gulch to American Fork. Comparing loads for Mary Ellen Gulch in the two studies indicates that metal loads could be substantially underestimated for planning purposes without the detailed catchment approach for the low-flow conditions in these studies. A mass-loading approach provides both the needed quantification of metal loading and the spatial detail to guide remediation decisions that would be the most effective in the catchments

    Charcot-Marie-Tooth disease is a group of hereditary peripheral neuropathies that share clinical characteristics of progressive distal muscle weakness and atrophy, foot deformities, distal sensory loss, as well as diminished tendon reflexes. Hundreds of causative DNA changes have been found, but much of the genetic basis of the disease is still unexplained. Mutations in the ALS5/SPG11/KIAA1840 gene are a frequent cause of autosomal recessive hereditary spastic paraplegia with thin corpus callosum and peripheral axonal neuropathy, and account for ∼ 40% of autosomal recessive juvenile amyotrophic lateral sclerosis. The overlap of axonal Charcot-Marie-Tooth disease with both diseases, as well as the common autosomal recessive inheritance pattern of thin corpus callosum and axonal Charcot-Marie-Tooth disease in three related patients, prompted us to analyse the ALS5/SPG11/KIAA1840 gene in affected individuals with autosomal recessive axonal Charcot-Marie-Tooth disease. We investigated 28 unrelated families with autosomal recessive axonal Charcot-Marie-Tooth disease defined by clinical, electrophysiological, as well as pathological evaluation. Besides, we screened for all the known genes related to axonal autosomal recessive Charcot-Marie-Tooth disease (CMT2A2/HMSN2A2/MFN2, CMT2B1/LMNA, CMT2B2/MED25, CMT2B5/NEFL, ARCMT2F/dHMN2B/HSPB1, CMT2K/GDAP1, CMT2P/LRSAM1, CMT2R/TRIM2, CMT2S/IGHMBP2, CMT2T/HSJ1, CMTRID/COX6A1, ARAN-NM/HINT and GAN/GAN), for the genes related to autosomal recessive hereditary spastic paraplegia with thin corpus callosum and axonal peripheral neuropathy (SPG7/PGN, SPG15/ZFYVE26, SPG21/ACP33, SPG35/FA2H, SPG46/GBA2, SPG55/C12orf65 and SPG56/CYP2U1), as well as for the causative gene of peripheral neuropathy with or without agenesis of the corpus callosum (SLC12A6). Mitochondrial disorders related to Charcot-Marie-Tooth disease type 2 were also excluded by sequencing POLG and TYMP genes. An additional locus for autosomal recessive Charcot-Marie

    Carl Wilhelm Naundorff was buried in 1845 in Delft as Louis Charles, Duc de Normandie, 'Louis XVII'. However, the son of Louis XVI and Marie-Antoinette-Louis XVII--officially died in the Temple of Paris in 1795. In order to resolve the identity of Naundorff, mitochondrial DNA (mtDNA) D-loop sequences of his remains were compared with the sequences obtained from the hairs of two sisters of Marie-Antoinette, Marie-Antoinette herself, and with the sequences obtained from DNA samples of two living maternal relatives. The mtDNA sequence of a bone sample from Naundorff showed two nucleotide differences from the sequences of the three sisters and four differences from the sequences of living maternal relatives. Based on this evidence it becomes very unlikely that Naundroff is the son of Marie-Antoinette. PMID:9781047

    Marie Curie, née Maria Sklodowska, was born on November 7, 1867 in Warsaw (Poland). She suffered from leukaemia and died on June 4, 1934. She was buried with full honours at Pantheon. Marie Curie and her husband Pierre Curie discovered the radioactive elements Polonium (84Po210), Thorium (90Th232) and Radium (88Ra226). Marie Curie introduced the term radioactivity into science. She was the first woman who got Ph.D. in France, the first woman professor at Sorbonne, Paris and Medical Academy. Of all the women who have ever won the Nobel Prize, Marie Curie was the only who received it twice. During World War I Marie Curie designed a mobile x-ray room "radiologic car". Marie Curie had an x-ray machine installed into a car and demonstrated how to use its dynamo for electric power production necessary for the x-ray machine to work. She had 20 cars with moving radiological lab made and trained 150 people to work on them. She brought something radically new into military medicine--mobile x-ray diagnostics. With the discovery of radioactive elements a new medical branch, radiotherapy, was developed.

    X-linked Charcot-Marie-Tooth disease (CMTX1) is a clinically heterogeneous hereditary motor and sensory neuropathy with X-linked transmission. Common clinical manifestations of CMTX1 disease, as in other forms of Charcot-Marie-Tooth (CMT) disease, are distal muscle wasting and weakness, hyporeflexia, distal sensory disturbance, and foot deformities. Mutations in the connexin-32 gene (gap junction protein β1 [GJB1]) are responsible for CMTX1 disease. In this report, we describe a patient with CMTX1 disease presenting with recurrent attacks of transient and episodic acute demyelinating encephalomyelitis (ADEM)-like symptoms without previous signs of lower extremity weakness or foot deformities; the patient, as well as his asymptomatic mother, exhibited a novel GJB1 mutation (p.Met1Ile). Differential diagnosis of recurrent and transient ADEM-like illness, if unexplained, should include the possibility of CMTX1 disease.

    The 18th and 19th centuries were beset with new religious movements in the United States: Shakers, Latter Day Saints, Millerites, and Seventh Day Adventists to name a few. One group, Christian Science, held radically different views than their counterparts and their origins lay in the most unlikely of places, a perpetually ill and poor woman from New Hampshire. Much has been said about Mary Baker Eddy: some say that she was a prophet, others that she was a fraud. Herein no such judgments are made. This study seeks to look into the life of Mary Baker Eddy from a psychological lens in the hopes that insight can be gained into the founding of the First Church of Jesus Christ Scientist and perhaps to allay the binary of Mrs. Eddy as either prophet or fanatic.

    Our Lady of the Rockies (OLR) is a ninety-foot-tall statue of the Virgin Mary overlooking Butte, Montana, from its perch high atop the Continental Divide. In the popularized account, OLR is a uniquely local undertaking reflecting the community's character and pride. Yet OLR is far more than this, for it taps into a rich vein of cultural and spiritual tradition. As Mircea Eliade pointed out, the notion of the earth as female pervaded early Western civilizations. Mines were like the vagina of the earth, leading to the womb where metallic ores waxed like embryos. Accordingly, miners purified themselves through various rites to amend their violation. OLR began as a plan for a small, private altar. With the collapse of Butte's copper mining economy, unemployed miners rallied around the idea of building a major shrine to the Virgin Mary that would help restore the city's culture and economy.

    The recorded history of physics at William and Mary begins when Thomas Jefferson, the College's most distinguished alumnus, meets his mentor, Dr. William Small of Scotland, who opens his eyes to the wonders of natural philosophy. After the vicissitudes of the Revolution and the Civil War, physics enjoys a revival in the twentieth century, culminating in the creation of a Ph.D. program in the 1960s and the building of the William Small Physical Laboratory in Williamsburg. In the 1980s the modern era is launched by the establishment of the US Department of Energy's Jefferson Lab for nuclear physics in nearby Newport News. Today both Small Hall and Jefferson Lab are in the process of renovation. The legacies of Small and Jefferson for physics at William and Mary are secure! )

They reported their experience with 10 sporadic cases of Charcot-Marie-Tooth type 1A (CMT1A) in which it was demonstrated that the disease had arisen as the result of a de novo duplication. They analyzed the de novo-duplication families by using microsatellite markers and identified the parental origin of the duplication in eight cases. In one family the duplication was of maternal origin, whereas in the remaining seven cases it was of paternal origin. The authors concluded that their report was the first evidence of a de novo duplication of maternal origin, suggesting that this is not a phenomenon associated solely with male meiosis. 7 refs.

    St. Mary's parish church in Chojna was erected at the turn of XIV and XVc. in a shape of three aisles, hall church without transept, completed from the west with a single tower and from the east with polygonal presbytery with an ambulatory attached. The convergence of characteristic structural and decorative features with employed ones in medieval churches being attributed to Hinrich Brunsberg's fabric resulted in such a way, that also authorship of St. Mary in Chojna was assigned to this legendary architect and master builder of late Middle Ages period. The church was destroyed by fire during WWII in February 1945 and since then had remained as an open ruin. In 1997 reconstruction procedure of the church was begun under the leadership of the author and it still continues. This text consists of the sum of experiences connected with confronting design ideas and solutions with their executions on the site during construction works.

    As the most famous woman scientist of the twentieth century, there has been no shortage of books and articles on the life and career of Marie Curie (1867-1934). Her role as director of a laboratory-based research school in the new scientific field of radioactivity, a field which embraced both chemistry and physics, however, has never been examined. In recent years, there has been a growing interest in the question of research schools, and Morrell, Ravetz, Geison, and Klosterman, amongst others, have written on this subject. Using, in part, the methodology of Morrell, this paper investigates the role of Marie Curie as a school director in the Paris Faculty in the years 1907-14, examining the work and characteristics of her school and assessing her effectiveness as a director.

    The link between soil science and geology is personified in the American father and daughter: soil surveyor William Edgar Tharp (1870-1959) and oceanographic cartographer Marie Tharp (1920-2006). From 1904 to 1935, W.E. Tharp mapped soils in 14 states for the US Department of Agriculture, and campaigned during the late 1920s-early 1930s to raise awareness of the high rates of soil erosion from croplands. The lifestyle of the federal soil surveyor in the United States during the early 20th century involved frequent household moves, and it played a formative role in Marie Tharp’s childhood. Her path to a career in geology was molded by this family experience, by mentors encountered in the classroom, and by social barriers that faced women scientists of that era.

A CoP was initiated and developed including stakeholders from clinical, research, community and governmental backgrounds involved in a large multidisciplinary and multi-sectorial project: the Rehabilitation Living Lab in a Mall (RehabMaLL). This study aimed to evaluate the structure, process and outcomes of this CoP. A single case-study, using mixed-methods, evaluated the RehabMaLL CoP initiative after one year, based on Donabedian's conceptual evaluation model. Forty-three participants took part in the RehabMaLL CoP with 60.5% (n = 26) participating at least once on the online platform where 234 comments were posted. Four in-person meetings were held. Members expressed satisfaction regarding the opportunity to share knowledge with people from diverse backgrounds and the usefulness of the CoP for the RehabMaLL project. Collaboration led to concrete outcomes, such as a sensitization activity and a research project. Common challenges included lack of time and difficulty finding common objectives. A CoP can be a useful strategy to facilitate knowledge sharing on disability issues. Future research is necessary to determine strategies of increasing knowledge creation between members.

    The aim of this exploratory study was to determine the important features in content and usability of existing mobile applications evaluating environmental barriers and facilitators (EBF) to participation for persons with physical disabilities presenting mild communication or cognitive limitations. A rigorous process based on a user-centered design approach led to the identification of two relevant mobile applications to evaluate the EBF. An accessibility expert, the research team as well as five users then tested the mobile applications in a shopping mall. A thematic content analysis of the research team’s and users’ comments established 10 categories of key features that adequately respond to the needs of the clientele targeted in this study. In terms of content, granularity and contextualization of the information provided were considered important. With respect to usability, relevant features were place finding, rating system, presentation of results, compatibility, user-friendliness, aesthetics, credibility of the information as well as connectivity/interactiveness. The research team and the users agreed on some aspects such as aesthetics, but had different perspectives on features such as the rating system or the connectivity/interactiveness of the application. The users proposed new features suggesting that the existing mobile applications did not correspond to all their needs. PMID:25513999

    Motivation: Although many tools are available to study variation and its impact in single genomes, there is a lack of algorithms for finding such variation in metagenomes. This hampers the interpretation of metagenomics sequencing datasets, which are increasingly acquired in research on the (human) microbiome, in environmental studies and in the study of processes in the production of foods and beverages. Existing algorithms often depend on the use of reference genomes, which pose a problem when a metagenome of a priori unknown strain composition is studied. In this article, we develop a method to perform reference-free detection and visual exploration of genomic variation, both within a single metagenome and between metagenomes. Results: We present the MaryGold algorithm and its implementation, which efficiently detects bubble structures in contig graphs using graph decomposition. These bubbles represent variable genomic regions in closely related strains in metagenomic samples. The variation found is presented in a condensed Circos-based visualization, which allows for easy exploration and interpretation of the found variation. We validated the algorithm on two simulated datasets containing three respectively seven Escherichia coli genomes and showed that finding allelic variation in these genomes improves assemblies. Additionally, we applied MaryGold to publicly available real metagenomic datasets, enabling us to find within-sample genomic variation in the metagenomes of a kimchi fermentation process, the microbiome of a premature infant and in microbial communities living on acid mine drainage. Moreover, we used MaryGold for between-sample variation detection and exploration by comparing sequencing data sampled at different time points for both of these datasets.

  1. GPS Measurement of Tectonic Deformation and Isostatic Rebound in Marie Byrd Land, Antarctica

    The Ross embayment and western Marie Byrd Land are part of the West Antarctic rift system. The region is undergoing active deformation, but the rates and causes of deformation are essentially unknown. In December 1998 we installed three continuous and autonomous global positioning system (GPS) stations on outcrops in western Marie Byrd Land, with baselines between stations of about 100 kilometers. We recovered data for the sites in Marie Byrd Land during the 1998--1999 season and additional data in November 1999, November 2000, and January 2001. Results from three years of data collection indicate essentially no extension between McMurdo station (MBL4) and the network. The results show an overall length rate of -0.7+/- 3.5~mm/yr between MCM4 and the wMBL network. With additional years of measurements we should be able to discriminate whether this rate is near zero or not to about 1~mm/yr. We also expect to detect strain gradients within wMBL. The network also suggests a dome of uplift centered near the Rockefeller Mountains, with the maximum rate being in the Rockefeller Mountains of 12+/- 8~mm/yr. This is consistent with proposed post-glacial rebound for the region. The strain data from wMBL and the Transantarctic Mountains will enable us to construct models for tectonic extension and glacial rebound in the West Antarctic rift. The results will help determine whether active tectonic deformation is occurring in the Ross embayment. Crustal uplift could be occurring in western Marie Byrd Land due to isostatic rebound following the last glacial age. Tectonic extension, occurring in the embayment, could greatly influence global plate circuit calculations and constrain our understanding of the history of extension in the embayment and the consequent uplift history of the Transantarctic Mountains.

    The purpose of the Matter-Radiation Interactions in Extremes (MaRIE) facility at Los Alamos National Laboratory is to investigate the performance limits of materials in extreme environments. The MaRIE facility will utilize a 12 GeV linac to drive an X-ray Free-Electron Laser (FEL). Most of the same linac will also be used to perform electron radiography. The main linac is driven by two shorter linacs; one short linac optimized for X-FEL pulses and one for electron radiography. The RF systems have historically been the one of the largest single component costs of a linac. We will describe the details of the different types of RF systems required by each part of the linacs. Starting with the High Power RF system, we will present our methodology for the choice of RF system peak power and pulselength with respect to klystron parameters, modulator parameters, performance requirements and relative costs. We will also present an overview of the Low Level RF systems that are proposed for MaRIE and briefly describe their use with some proposed control schemes.

    We examined trends in species composition and abundance of the St. Marys River fish community. Abundance data were available approximately once every six years from 1975 through 2006, and size and age data were available from 1995 through 2006. We also compared survey data in 2006 with results of a concurrent creel survey that year, as well as data from prior surveys spanning a 69 year time frame. The St. Marys River fish community was best characterized as a coolwater fish community with apparent little variation in species composition, and only slight variation in overall fish abundance since 1975. However, we did find recent trends in abundance among target species sought by anglers: centrarchids increased, percids appeared stable, and both northern pike Esox lucius and cisco Coregonus artedii declined. Survey results suggested that walleye (Sander vitreus) and yellow perch (Perca flavescens) experienced moderate exploitation but benefited from recent strong recruitment and faster growth. Mechanisms underlying declines of northern pike and cisco were not clear; reduced abundance could have resulted from high exploitation, variation in recruitment, or a combination of both factors. Despite these challenges, the St. Marys River fish community appears remarkably stable. We suggest that managers insure that creel surveys occur simultaneously with assessments, but periodic gill net surveys may no longer provide adequate data in support of recent, more complex management objectives. While additional surveys would add costs, more frequent data might ensure sustainability of a unique fish community that supports a large proportion of angler effort on Lake Huron.

    Since a notice published in 1811 in the Biographie universelle of Michaud, it has been supposed that the famous "Mademoiselle Biheron" of the XVIIIth century, who made artificial anatomies and was especially admired by Diderot, had Marie Catherine as her Christian names. It was a mistake which would invalidate for almost two centuries all the researches on the biography of this anatomist and artist. No one even knew the date and the circumstances of her death. The author, having discovered her true names - Marie Marguerite -, realised many investigations on her and her family. He worked especially on notarian archives, both in Paris, where she was born, and in the north of the old Maine province (present Sarthe department), from which her father, who was a Parisian apothecary, originated. Also he recalls the essential part that this Marie Marguerite Biheron (1719-1795) played in the evolution of the ideas concerning the teaching and medical use of anatomical data. Her contribution in that field was one of those which prepared the important reforms which would take place at the end of the century, at the time of the Convention, conducting in particular to the development of modern surgery.

  11. What Mary Toft Felt: Women’s Voices, Pain, Power and the Body

    2015-01-01

    In autumn 1726, Mary Toft began to deliver rabbits in Godalming, Surrey. The case became a sensation and was reported widely in newspapers, popular pamphlets, poems and caricatures. Toft was attended by at least six different doctors, some members of the Royal College of Physicians or attached to the Royal Court, but no doctor declared the affair a hoax until Toft herself confessed on 7 December 1726. This article focuses on Toft’s three surviving confessions in order to explore not the doctors or even wider representations of the affair but instead the person of Mary Toft herself. These rare sources give rare insight into one woman’s experiences of reproduction in the early eighteenth century. The essay engages with recent work on recovering women’s voices in the past, reconstructing Mary Toft’s words and her embodied and affective experience of the affair. These documents suggest a revision to our understanding of the hoax of 1726, one that situates the affair not in the context of the scientific revolution and Enlightenment or the assumption of men’s control over midwifery, but instead in the context of power dynamics amongst women in the practices of early-modern reproduction and birth.

    The story of Victor Frankenstein's quest to conquer death produced a legacy that has endured for almost 200 years. Powerful in its condemnation of the scientist's quest to achieve knowledge at any cost, Mary Shelley's Frankenstein is one of the most enduring novels of all time. It has never been out of print and has been translated to both stage and screen many times since its "birth." Numerous novels, short stories, and scripts have drawn upon Shelley's primary theme: the creation of a living organism from the dead, dying, and decaying body parts of human beings. Although Mary does not provide details of the animation process, particularly in her first edition, the process has been explored with a great deal of imagination and originality in the various cinematic portrayals of the story. Equally important as the theme of the scientist's quest for knowledge is the role that a creator plays in the life of its creation. Mary Shelley's novel pondered on how rejection would affect the offspring of such "unnatural" origins. In keeping with the "scientific" basis of the Creature's birth, cinematic portrayals attempted to provide a scientific rationale for the Creature's descent into madness and its evil behavior. From Robert Florey's initial script for the 1931 film directed by James Whale to the more recent films and television series, an abnormal brain is considered to be the cause of the madness and malignity of the Creature.

  13. Peroneal nerve branching suggests compression palsy in the deformities of Charcot-Marie Tooth disease.

    2006-10-01

    Altered expression of the PMP-22 protein may be implicated in Charcot-Marie-Tooth disease and the much rarer disease, hereditary liability to pressure palsy. An element of chronic pressure palsy may explain the unique distribution of motor imbalance in patients with Charcot-Marie-Tooth disease. If this is the case, innervation of the lateral leg motor units should show sufficient anatomic segregation to explain the variable disease patterns. Twelve fresh cadaver specimens were dissected to examine the innervation of the anterior and lateral compartment muscles from the peroneal nerve. Nine specimens had a branch to the peroneus longus at or proximal to nerve passage of the posterior fibular neck. The first branch to the peroneus longus was 2.1 +/- 6.7 mm proximal, and the first branch to the peroneus brevis was 110.9 +/- 19 mm distal. The nerve to the tibialis anterior originated within 5 mm of the reference point and wrapped transversely along the fibular neck for 17.2 +/- 1.4 mm. These discrete pathways to the individual motor units in the anterolateral leg were consistent with the possible implication of chronic pressure palsy in the patterns of atrophy in Charcot-Marie-Tooth disease.

  15. Shortened internodal length of dermal myelinated nerve fibres in Charcot–Marie-Tooth disease type 1A

    Charcot–Marie-Tooth disease type 1A is the most common inherited neuropathy and is caused by duplication of chromosome 17p11.2 containing the peripheral myelin protein-22 gene. This disease is characterized by uniform slowing of conduction velocities and secondary axonal loss, which are in contrast with non-uniform slowing of conduction velocities in acquired demyelinating disorders, such as chronic inflammatory demyelinating polyradiculoneuropathy. Mechanisms responsible for the slowed conduction velocities and axonal loss in Charcot–Marie-Tooth disease type 1A are poorly understood, in part because of the difficulty in obtaining nerve samples from patients, due to the invasive nature of nerve biopsies. We have utilized glabrous skin biopsies, a minimally invasive procedure, to evaluate these issues systematically in patients with Charcot–Marie-Tooth disease type 1A (n = 32), chronic inflammatory demyelinating polyradiculoneuropathy (n = 4) and healthy controls (n = 12). Morphology and molecular architecture of dermal myelinated nerve fibres were examined using immunohistochemistry and electron microscopy. Internodal length was uniformly shortened in patients with Charcot–Marie-Tooth disease type 1A, compared with those in normal controls (P < 0.0001). Segmental demyelination was absent in the Charcot–Marie-Tooth disease type 1A group, but identifiable in all patients with chronic inflammatory demyelinating polyradiculoneuropathy. Axonal loss was measurable using the density of Meissner corpuscles and associated with an accumulation of intra-axonal mitochondria. Our study demonstrates that skin biopsy can reveal pathological and molecular architectural changes that distinguish inherited from acquired demyelinating neuropathies. Uniformly shortened internodal length in Charcot–Marie-Tooth disease type 1A suggests a potential developmental defect of internodal lengthening. Intra-axonal accumulation of mitochondria provides new insights into the

    Two groups of teneral flies (aged less than 32 hours) of Glossina morsitans morsitans (Mall) were fed separately on two rats that had been infected with Trypanosoma (Nannomonas) congolense IL 1180, among which one had a low parasitaemia (antilog 5.4-5.7) and the other a high parasitaemia (antilog 7.8-8.1). Following to the two modes of parasitaemia, variations of the procyclic indexes were found between males and females. When both sexes were considered, it was found that the intestinal infection rate was relatively higher in the flies that were fed on the rat with a low parasitaemia than in those fed on the rat with a high parasitaemia. Although no significant differences in metacyclic indexes were observed between sexes, the mature infection rate was most pronounced in the flies that were fed on the rat with high parasitaemia. When both sexes were considered, the vectorial competence (VC) reached 0.5532 and 0.5521 in the flies that had been fed on the rats with low and high parasitaemia, respectively. The VC of the two modes of infectious feeding was not significantly different. However, when considering the parasitaemia of antilog 5.4-5.7, the VC was relatively more important in the females than in the males. No significant difference in VC was detected between sexes when considering the antilog 7.8-8.1 parasitaemia. It was found that there is discrepancy in the way the metacyclic infection and the VC evolve in relation to the procyclic infection, suggesting that the intensity of the parasitaemia only influences the intestinal stage.

    The population of Coregonus artedi in the St. Marys River, between lakes Superior and Huron, was sampled and otoliths were analyzed for oxygen isotopic composition to determine whether the fish are residents in the St. Marys River and its warm bays or migrants to and from cold Lake Huron. Otoliths were extracted, sectioned, and growth ring-specific samples of calcium carbonate were milled to obtain samples for determination of oxygen isotope ratios (18O values). The 18O values of calcium carbonate (CaCO3) in accretionary structures such as otoliths allow calculation of growth temperatures of the fish, because of differential fractionation of oxygen isotopes at different temperatures. Growth temperatures of 10 St. Marys River lake herring were compared with lake and catch data as well as growth temperatures of lake herring collected from Lake Huron and other ciscoes from the Great Lakes. Results of this analysis indicate that these fish remained in the bays of the St. Marys River for their entire life history. After their second year they grew at average temperatures between 11 C and 13 C, consistent with temperature in the warmer bays of the St. Marys River and 6 C higher than expected for growth of this species in Lake Huron.

    We previously found that the K141N mutation in heat shock protein B8 (HSPB8) was responsible for Charcot-Marie-Tooth disease type 2L in a large Chinese family. The objective of the present study was to generate a transgenic mouse model bearing the K141N mutation in the human HSPB8 gene, and to determine whether this K141NHSPB8 transgenic mouse model would manifest the clinical phenotype of Charcot-Marie-Tooth disease type 2L, and consequently be suitable for use in studies of disease pathogenesis. Transgenic mice overexpressing K141NHSPB8 were generated using K141N mutant HSPB8 cDNA cloned into a pCAGGS plasmid driven by a human cytomegalovirus expression system. PCR and western blot analysis confirmed integration of the K141NHSPB8 gene and widespread expression in tissues of the transgenic mice. The K141NHSPB8 transgenic mice exhibited decreased muscle strength in the hind limbs and impaired motor coordination, but no obvious sensory disturbance at 6 months of age by behavioral assessment. Electrophysiological analysis showed that the compound motor action potential amplitude in the sciatic nerve was significantly decreased, but motor nerve conduction velocity remained normal at 6 months of age. Pathological analysis of the sciatic nerve showed reduced myelinated fiber density, notable axonal edema and vacuolar degeneration in K141NHSPB8 transgenic mice, suggesting axonal involvement in the peripheral nerve damage in these animals. These findings indicate that the K141NHSPB8 transgenic mouse successfully models Charcot-Marie-Tooth disease type 2L and can be used to study the pathogenesis of the disease. PMID:25206829

    The ganglioside-induced differentiation-associated protein 1 (GDAP1) is a mitochondrial fission factor and mutations in GDAP1 cause Charcot-Marie-Tooth disease. We found that Gdap1 knockout mice (Gdap1(-/-)), mimicking genetic alterations of patients suffering from severe forms of Charcot-Marie-Tooth disease, develop an age-related, hypomyelinating peripheral neuropathy. Ablation of Gdap1 expression in Schwann cells recapitulates this phenotype. Additionally, intra-axonal mitochondria of peripheral neurons are larger in Gdap1(-/-) mice and mitochondrial transport is impaired in cultured sensory neurons of Gdap1(-/-) mice compared with controls. These changes in mitochondrial morphology and dynamics also influence mitochondrial biogenesis. We demonstrate that mitochondrial DNA biogenesis and content is increased in the peripheral nervous system but not in the central nervous system of Gdap1(-/-) mice compared with control littermates. In search for a molecular mechanism we turned to the paralogue of GDAP1, GDAP1L1, which is mainly expressed in the unaffected central nervous system. GDAP1L1 responds to elevated levels of oxidized glutathione by translocating from the cytosol to mitochondria, where it inserts into the mitochondrial outer membrane. This translocation is necessary to substitute for loss of GDAP1 expression. Accordingly, more GDAP1L1 was associated with mitochondria in the spinal cord of aged Gdap1(-/-) mice compared with controls. Our findings demonstrate that Charcot-Marie-Tooth disease caused by mutations in GDAP1 leads to mild, persistent oxidative stress in the peripheral nervous system, which can be compensated by GDAP1L1 in the unaffected central nervous system. We conclude that members of the GDAP1 family are responsive and protective against stress associated with increased levels of oxidized glutathione.

  20. Marys Lake 69/115-kV transmission line upgrade and substation expansion projects

    1996-05-01

    Western Area Power Administration (Western) and the Platte River Power Authority (Platte River) propose to upgrade portions of the existing electric transmission and substation system that serves the Town of Estes Park, Colorado. The existing transmission lines between the Estes Power Plant Switchyard and the Marys Lake Substation include a 115,000 volt (115-kV) line and 69,000 volt (69-kV) line. Approximately one mile is a double-circuit 115/69-kV line on steel lattice structures, and approximately two miles consists of separate single-circuit 115-kV and a 69-kV lines, constructed on wood H-Frame structures. Both lines were constructed in 1951 by the US Bureau of Reclamation. The existing transmission lines are on rights-of-way (ROW) that vary from 75 feet to 120 feet and are owned by Western. There are 48 landowners adjacent to the existing ROW. All of the houses were built adjacent to the existing ROW after the transmission lines were constructed. Upgrading the existing 69-kV transmission line between the Marys Lake Substation and the Estes Power Plant Switchyard to 115-kV and expanding the Marys Lake Substation was identified as the most effective way in which to improve electric service to Estes Park. The primary purpose and need of the proposed project is to improve the reliability of electric service to the Town of Estes Park. Lack of reliability has been a historical concern, and reliability will always be less than desired until physical improvements are made to the electrical facilities serving Estes Park.

    Marie Byrd Land, Antarctica, is a major part of the proto-Pacific supercontinental margin. On the basis of new geochronological and geochemical data relating to its pre-Jurassic evolution, Marie Byrd Land is subdivided into western or interior ("Ross") and eastern or exterior ("Amundsen") provinces, equivalent to two superterranes in New Zealand. The Ross province is characterized by Cambrian? metagraywackes and I-type orthogneiss dated at 505±5 Ma by U-Pb SHRIMP (Sensitive High Resolution Ion Microprobe). Its magmatic record consists of Devonian-Carboniferous (375±5 Ma and circa 339±6 Ma), predominantly I-type granitoids, and further minor granitic magmatism in Permo-Triassic times. This Paleozoic history is comparable to that of the Gondwana margin in northern Victoria Land, western New Zealand, and SE Australia. The Amundsen province has no observed Paleozoic graywacke succession; evidence from Rb-Sr and U-Pb SHRIMP dating supports calc-alkaline granitoid events in Ordovician/Silurian (450-420 Ma) and Permian (276±2 Ma) times. The latter may be the previously unknown source of Permian volcanic detritus in the Ellsworth and Transantarctic mountains. The Amundsen province is considered to be the equivalent of the Median Tectonic Zone of New Zealand, and arc magmatism of comparable ages is found in the Antarctic Peninsula and Thurston Island. The underlying lithosphere of the two provinces may be distinguished by Nd isotope data; granitoids and metasedimentary rocks of the Ross province have Meso-Proterozoic Nd model ages, generally 1300-1500 Ma, compared to 1000-1300 Ma for the Amundsen province. On the basis of published palaeomagnetic data, the two provinces amalgamated to form Marie Byrd Land in mid-Cretaceous times, only shortly before rifting of the New Zealand continental block away from Antarctica.

These atypical features widen the clinical spectrum of CMT1A, leading to interesting observations about PMP22 gene related disorders and varied clinical expression of similar genetic mutations.

    1973-01-01

    This paper presents the derivation of the recursive algorithms necessary for real-time digital detection of M-ary known signals that are subject to independent multiplicative and additive Gaussian noises. The motivating application is minimum probability of error detection of digital data-link messages aboard civil aircraft in the earth reflection multipath environment. For each known signal, the detector contains one Kalman filter and one probability computer. The filters estimate the multipath disturbance. The estimates and the received signal drive the probability computers. Outputs of all the computers are compared in amplitude to give the signal decision. The practicality and usefulness of the detector are extensively discussed.

    Charcot-Marie-Tooth Neuropathy Score second version (CMTNSv2) is a validated clinical outcome measure developed for use in clinical trials to monitor disease impairment and progression in affected CMT patients. Currently, all items of CMTNSv2 have identical contribution to the total score. We used Rasch analysis to further explore psychometric properties of CMTNSv2, and in particular, category response functioning, and their weight on the overall disease progression. Weighted category responses represent a more accurate estimate of actual values measuring disease severity and therefore could potentially be used in improving the current version.

    The proposed Matter-Radiation Interactions in Extremes (MaRIE) facility at the Los Alamos National Laboratory will include a 50-keV X-Ray Free-Electron Laser (XFEL), a significant extension from planned and existing XFEL facilities. To prevent an unacceptably large energy spread arsing from energy diffusion, the electron beam energy should not exceed 20 GeV, which puts a significant constraint on the beam emittance. A 100-pC baseline design is presented along with advanced technology options to increase the photon flux and to decrease the spectral bandwidth through pre-bunching the electron beam.

    We present a 3⅓-year-old girl with severe Charcot-Marie-Tooth disease type 1 (Dejerine-Sottas disease), who was a compound heterozygote carrying a deletion of the whole peripheral myelin protein 22 (PMP22) and a deletion of exon 5 in the other PMP22 allele. Haplotype analyses and sequence determination revealed a 11.2 kb deletion spanning from intron 4 to 3'-region of PMP22, which was likely generated by nonhomologous end joining. Severely affected patients carrying a PMP22 deletion must be analyzed for the mutations of the other copy of PMP22. PMID:20739940

    As the geosynchronous orbit for satellite communication becomes increasingly crowded, the effect of adjacent satellite interference is of primary concern. The saddle-point approximation technique for evaluating the error probability of M-ary PSK systems with adjacent satellite interference is described. In comparison with previous methods, this technique has the advantages of both computational simplicity and accuracy. Results include a sample calculation to study the effect of fading on the uplink of a 12/14-GHz quadraphase-shift-keying system with 3-degree satellite spacings and 3-m earth stations.

    Mary Mallon was born in 1869 in Ireland and emigrated to the US in 1884. She had worked in a variety of domestic positions for wealthy families prior to settling into her career as a cook. As a healthy carrier of Salmonella typhi her nickname of “Typhoid Mary” had become synonymous with the spread of disease, as many were infected due to her denial of being ill. She was forced into quarantine on two separate occasions on North Brother Island for a total of 26 years and died alone without friends, having evidently found consolation in her religion to which she gave her faith and loyalty.

Focusing on the processes of negotiation between women and men in farming families and rural communities, Neth illuminated the relationship between women's work and their power. Tracing the dense networks that connected farm families, she also showed how cooperation in work generated and sustained radical farm movements.

    This study reports the positive physical, emotional and psychosocial changes induced by sport activity in a Paralympic swimmer with Charcot-Marie-Tooth (CMT) type 4A. When we compared evaluations before initiating sport activity with those after five years of competitive activity, we found: i) increased proximal muscles strength of upper limbs; ii) augmented ability to propel wheelchair independently; iii) improved quality of life; iv) reduced trait anxiety and striking improvement of depression; v) enhanced self-esteem. Longitudinal studies in large cohorts to evaluate the positive effects of sport activity are needed to support provision of evidence-based advice to patients and families. PMID:27460291

    We analyze the performance of the maximizer of the posterior marginals (MPM) detector for code division multiple access (CDMA) multiuser detection with M-ary phase shift keying (M-ary PSK) in the large system limit by the replica method. The obtained theory agrees with computer simulation reasonably well. We also derive the theory in the case of the large M limit and discuss the dependence of the properties of M-ary PSK CDMA communication on M. We show that the waterfall phenomenon occurs for both the finite and infinite values of M. We also show that a value of M for which the decoded phase information on the original user symbol becomes minimum exists. Furthermore, we discuss the relationship between the theory based on the replica method and that based on self-consistent signal-to-noise analysis (SCSNA).

    The West Antarctic Rift System is one of the largest continental rifts on Earth. Because it is obscured by the West Antarctic Ice Sheet, its evolution is still poorly understood. Here we present the first low-temperature thermochronology data from eastern Marie Byrd Land, an area that stretches ~ 1000 km along the rift system, in order to shed light on its development. Furthermore, we petrographically analysed glacially transported detritus deposited in the marine realm, offshore Marie Byrd Land, to augment the data available from the limited terrestrial exposures. Our data provide information about the subglacial geology, and the tectonic and morphologic history of the rift system. Dominant lithologies of coastal Marie Byrd Land are igneous rocks that intruded (presumably early Paleozoic) low-grade meta-sedimentary rocks. No evidence was found for un-metamorphosed sedimentary rocks exposed beneath the ice. According to the thermochronology data, rifting occurred in two episodes. The earlier occurred between ~ 100 and 60 Ma and led to widespread tectonic denudation and block faulting over large areas of Marie Byrd Land. The later episode started during the Early Oligocene and was confined to western Pine Island Bay area. This Oligocene tectonic activity may be linked kinematically to previously described rift structures reaching into Bellingshausen Sea and beneath Pine Island Glacier, all assumed to be of Cenozoic age. However, our data provide the first direct evidence for Cenozoic tectonic activity along the rift system outside the Ross Sea area. Furthermore, we tentatively suggest that uplift of the Marie Byrd Land dome only started at ~ 20 Ma; that is, nearly 10 Ma later than previously assumed. The Marie Byrd Land dome is the only extensive part of continental West Antarctica elevated above sea level. Since the formation of a continental ice sheet requires a significant area of emergent land, our data, although only based on few samples, imply that extensive

    mariPOC is a novel point-of-care test system for rapid detection of respiratory tract infections. We compared the performance of the mariPOC test to that of bacterial culture for detecting group A streptococcus (GAS) in 219 pharyngitis patients (ages 1–64 years) and 109 healthy asymptomatic controls (ages 19–69 years). In addition, 42 patient samples were analyzed by quantitative PCR (qPCR). Of the 219 pharyngeal patient samples, 32 were positive in a GAS bacterial culture (prevalence 15%) and 65 (30%) in the mariPOC test. The amount of GAS in samples reported positive by the mariPOC test and negative by culture was, on average, 10-fold less than that of those positive in both methods. This indicated that the negative results in bacterial cultures were due to lower sensitivity. The qPCR results were positive and in line with the mariPOC results in 43% of the discordant samples studied. Two GAS culture-positive samples were negative by the mariPOC test. The prevalences of GAS in the control subjects were 2% and 6% by culture and mariPOC results, respectively. We conclude that the mariPOC antigen detection test is more sensitive than the conventional bacterial culture for the detection of GAS among symptomatic pharyngitis patients. The higher prevalence of GAS by the mariPOC test among symptomatic patients was probably not due to carriership, since among the control patients, the difference in the prevalence of GAS by the mariPOC test and culture was not nearly as high, 15% versus 4%, respectively. Clinical trials are needed to show the clinical importance of our findings. PMID:25903570

    Princess Marie Bonaparte is an important figure in the history of psychoanalysis, remembered for her crucial role in arranging Freud's escape to safety in London from Nazi Vienna, in 1938. This paper connects us to Bonaparte's work on Poe's short stories. Founded on concepts of Freudian theory and an exhaustive review of the biographical facts, Marie Bonaparte concluded that the works of Edgar Allan Poe drew their most powerful inspirational force from the psychological consequences of the early death of the poet's mother. In Bonaparte's approach, which was powerfully influenced by her recognition of the impact of the death of her own mother when she was born-an understanding she gained in her analysis with Freud-the thesis of the dead-living-mother achieved the status of a paradigmatic key to analyze and understand Poe's literary legacy. This paper explores the background and support of this hypothesis and reviews Bonaparte's interpretation of Poe's most notable short stories, in which extraordinary female figures feature in the narrative.

    Recent investigations of extreme environments have revealed numerous bioactive natural products. However, biosurfactant-producing strains from deep sea extreme environment are largely unknown. Here, we show that Dietzia maris As-13-3 isolated from deep sea hydrothermal field could produce di-rhamnolipid as biosurfactant. The critical micelle concentration (CMC) of the purified di-rhamnolipid was determined to be 120 mgL−1, and it lowered the surface tension of water from 74 ± 0.2 to 38 ± 0.2 mN m−1. Further, the alkane metabolic pathway-related genes and di-rhamnolipid biosynthesis-related genes were also analyzed by the sequencing genome of D. maris As-13-3 and quantitative real-time PCR (Q-PCR), respectively. Q-PCR analysis showed that all these genes were induced by n-Tetradecane, n-Hexadecane, and pristane. To the best of our knowledge, this is first report about the complete pathway of the di-rhamnolipid synthesis process in the genus Dietzia. Thus, our study provided the insights into Dietzia in respects of oil degradation and biosurfactant production, and will help to evaluate the potential of Dietzia in marine oil removal.

    The Boston Strangler was one of the United States' most notorious serial killers, raping and strangling with decorative ligatures thirteen woman in Boston during the early 1960s. Albert DeSalvo, never a suspect in the slayings, confessed in prison (where he was later murdered) to being the Boston Strangler, and the investigation largely ended. Mary Sullivan was the last victim of the Boston Strangler, found sexually assaulted and strangled in her Boston apartment in 1964. Recently, a team of forensic scientists undertook the exhumation and subsequent scientific analysis of Mary Sullivan's remains, in hope of finding consistencies or inconsistencies between DeSalvo's confessed description of the murder and any evidence left behind. Included in these analyses was extensive DNA testing of all UV fluorescent material associated with the body. The large majority of results were negative, however, fluorescent material located on the underwear and entwined in her pubic hair generated two human mitochondrial DNA sequences. Neither of these matched the victim nor members of the forensic team who worked on the evidence. Most importantly, neither DNA sequence could have originated from Albert DeSalvo.

    Background Charcot-Marie-Tooth disease is the most common inherited nerve disorder and typically presents with pes cavus foot deformity and ankle equinus during childhood. Level in the variation of symmetry of musculoskeletal lower limb involvement across the clinical population is unknown, despite early reports describing gross asymmetry. Methods We measured foot alignment and ankle flexibility of the left and right limbs using accurate and reliable standardised paediatric outcome measures in 172 patients aged 3–20 years with a variety of disease subtypes recruited from the United States, United Kingdom, Italy and Australia. Findings While a large range of differences existed between left and right feet for a small proportion of children, there was no overall significant difference between limbs. Interpretation There are two important implications of these findings. Children with Charcot-Marie-Tooth disease generally exhibit symmetrical foot alignment and ankle flexibility between limbs. As such, analysing one limb only for biomechanical-related research is appropriate and satisfies the independence requirements for statistical analysis. However, because there are large differences between feet for a small proportion of children, an individualised limb-focused approach to clinical care is required. PMID:22424781

    Copy number variations (CNVs) are important in relation to diversity and evolution but can sometimes cause disease. The most common genetic cause of the inherited peripheral neuropathy Charcot-Marie-Tooth disease is the PMP22 duplication; otherwise, CNVs have been considered rare. We investigated CNVs in a population-based sample of Charcot-Marie-Tooth (CMT) families. The 81 CMT families had previously been screened for the PMP22 duplication and point mutations in 51 peripheral neuropathy genes, and a genetic cause was identified in 37 CMT families (46%). Index patients from the 44 CMT families with an unknown genetic diagnosis were analysed by whole-genome array comparative genomic hybridization to investigate the entire genome for larger CNVs and multiplex ligation-dependent probe amplification to detect smaller intragenomic CNVs in MFN2 and MPZ. One patient had the pathogenic PMP22 duplication not detected by previous methods. Three patients had potentially pathogenic CNVs in the CNTNAP2, LAMA2, or SEMA5A, that is, genes related to neuromuscular or neurodevelopmental disease. Genotype and phenotype correlation indicated likely pathogenicity for the LAMA2 CNV, whereas the CNTNAP2 and SEMA5A CNVs remained potentially pathogenic. Except the PMP22 duplication, disease causing CNVs are rare but may cause CMT in about 1% (95% CI 0–7%) of the Norwegian CMT families. PMID:25648254

    St Mary's Cathedral is the Archbishop church of the Archdiocese in Perth in Western Australia. The presented sacral building was built in neo-Gothic style during the years 1863-1865. Cathedral was officially dedicated and opened for the service on 29th January, 1865. In 1973 was proclaimed the Marian Sanctuary and now represents one of the largest religious facilities in Perth. In 2005, the city authorities, together with the Archdiocese took a collective decision on the necessity of a comprehensive renovation of this sacred object. The renovation was due to the technical condition and the lack of usability of the object. The author of the paper had the opportunity to experience these problems by visiting this place several times, first time in 1989 and next years. Thus, the renovation of the present Cathedral was in its assumption not only to perform maintenance of the building and its specific architectural elements but also to increase its functional features - usable for the faithful and tourists. Reconstruction of St Mary's Cathedral in Perth can be a good example increasing the wider functionality of such facilities while keeping their antique and historical qualities. In this paper the above-mentioned issues will be more widely developed by the author.

    On spring 2001 and fall 2002, we carried out two magnetic surveys over a large unexcavated part of Mari (Tell Hariri, Syria), an important Mesopotamian city which has revealed three main occupation phases during the third and the second millennia BC and was destroyed by the King of Babylon Hammurabi. Both surveys were performed using a Geometrics magnetic gradiometer of caesium vapour allowing a high measurement sensivity. This sensivity was clearly necessary to retrieve magnetic anomalies linked to buried structures (houses, streets, etc…) made of adobe bricks. The first survey was in fact a limited test (over approximately two hectares) in order to see if the employed technique was indeed effective to recover some details of the city organisation. This test was successful as we observed several houses and, more important, a large band which we associated to a main street going from the Palace, at the top of the tell, to a gate in the city wall. The second survey was thus more extended (over approximately 11 hectares) and gave new informations on the network of streets and buildings in Mari. We will present all the results, which clearly illustrate the potential of the magnetic method in the adobe brick context.

    Gartner, C B

    1996-05-01

    In 1864, Dean Edwin Fussell of the Female Medical College of Pennsylvania tried to prevent Mary Putnam (later the eminent physician Mary Putnam Jacobi) from graduating. He claimed she had not fulfilled the requirements, and that granting her degree would give critics ammunition for their charges that a medical school for women debased the standards of the profession. In his writings and speeches both before and after this incident, Fussell made clear his belief that women in medicine should be held to higher and stricter standards than those applied to men in order to win acceptance. Fussell's case against Putnam, documented in the Minute Books of the Faculty and Board of Corporators of the college, was resolved, but this conflict raises larger issues. According to evidence in these records and the words of Fussell and those who knew him, Fussell emerges as a weak individual in a position of power in a weak institution who understood only quantitative measures of competence. This leads to the proposition that weak leaders in weak institutions today may continue to impose disparate standards on women and thereby adversely affect their careers.

    A strictly aerobic, Gram-negative, apricot-pigmented, non-motile, rod-shaped strain designated KMU-14(T) was isolated from seawater collected from the coastal zone of Yokji Island, Gyeongsangnam-do, Republic of Korea. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the novel isolate was affiliated with the genus Lysobacter within the class Gammaproteobacteria and that it showed the highest sequence similarity (97.1 %) to Lysobacter concretionis Ko07(T). The hybridization value for DNA-DNA relatedness between the strains of KMU-14(T) and L. concretionis Ko07(T) was 34.8 %, which was lower than 70 %, the recommended delineation value for differentiation of species. The DNA G+C content of strain KMU-14(T) was 64.9 mol%. The major respiratory quinone was ubiquinone 8 (Q-8), and iso-C15:0, iso-C16:0, and 10-methyl C16:0 and/or iso-C17:1 ω9c were the major (>10 %) cellular fatty acids. A polar lipid profile was present consisting of diphosphatidylglycerol, phosphatidylethanolamine, an unidentified phosphoglycolipid, two unidentified aminophospholipids, and two unidentified phospholipids. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel species for which the name Lysobacter maris sp. nov. is proposed. The type strain of L. maris sp. nov. is KMU-14(T) (=KCTC 42381(T) =NBRC 110750(T)). PMID:26616671

    2014-12-01

    Suprathreshold stochastic resonance is a form of noise-enhanced processing that is observed only when more than one noisy nonlinear signal processing element is combined in a parallel array, such as in biological and engineered sensory transduction. The case of binary threshold nonlinearities combined into arrays of independently noisy components has previously been studied extensively, and quantified in terms of how information transmission through the array varies with the input noise level, and the number of elements, N. Here we generalise this setup to arrays of N identical M-ary threshold nonlinearities. We show that enhanced suprathreshold stochastic resonance occurs for M≥ 1 and N > 1, implying that M identical quantizing sensors can be combined to provide higher resolution than a single sensor, provided they are independently noisy. We also study the system's scaling with M and N and conclude that although binary quantizing nonlinearities are superior to M-ary nonlinearities in the presence of large noise, the opposite holds in the presence of small noise. This suggests that multiple identical but coarse-resolution sensors can be useful for acquiring low SNR signals while few high-resolution identical sensors are superior for high SNR signals.

    From March 2002, the MARIE (Martian Radiation Environment Experiment) instrument of NASA-JSC onboard the 2001 Mars Odyssey spacecraft has been providing radiation data from the Martian orbit. During the past two years, the orbit alignment of Mars-Sun-Earth provided a wealth of opportunity between 180 degrees (August 2002) and 0 degrees (October 2003). During this time, the MARIE data included the background GCR (Galactic Cosmic Rays) and several SPE (Solar Particle Events) enhanced radiation dose-rate measurements at Mars. The MARIE instrument provided a unique data set of radiation dose-rate at Mars from the active regions on the solar disk facing the Mars side. The SPE observations of October 2002 at Mars by the MARIE instrument are unique and there were no indications of these events towards the Earth at that time. Nearly 40 times increase in the quiet-time GCR dose-rate was noted from about 25 mradday to nearly 1000 mradday at Mars. Radiation dose-rate enhancement was not observed toward the Earth or in the Low Earth Orbit (LEO) during this time. Understanding the active regions on the Sun that are likely to result into SPE on the far side will also be of concern for future deep space explorations beyond LEO. We present the observations of these SPE enhanced dose rates due to the active regions from the far side of the Sun with the 3D visualization of solar disks facing Mars and Earth.

    See Scherer (doi:10.1093/awv279) for a scientific commentary on this article.Charcot-Marie-Tooth type 1 neuropathies are inherited disorders of the peripheral nervous system caused by mutations in Schwann cell-related genes. Typically, no causative cure is presently available. Previous preclinical data of our group highlight the low grade, secondary inflammation common to distinct Charcot-Marie-Tooth type 1 neuropathies as a disease amplifier. In the current study, we have tested one of several available clinical agents targeting macrophages through its inhibition of the colony stimulating factor 1 receptor (CSF1R). We here show that in two distinct mouse models of Charcot-Marie-Tooth type 1 neuropathies, the systemic short- and long-term inhibition of CSF1R by oral administration leads to a robust decline in nerve macrophage numbers by ∼70% and substantial reduction of the typical histopathological and functional alterations. Interestingly, in a model for the dominant X-linked form of Charcot-Marie-Tooth type 1 neuropathy, the second most common form of the inherited neuropathies, macrophage ablation favours maintenance of axonal integrity and axonal resprouting, leading to preserved muscle innervation, increased muscle action potential amplitudes and muscle strengths in the range of wild-type mice. In another model mimicking a mild, demyelination-related Charcot-Marie-Tooth type 1 neuropathy caused by reduced P0 (MPZ) gene dosage, macrophage blockade causes an improved preservation of myelin, increased muscle action potential amplitudes, improved nerve conduction velocities and ameliorated muscle strength. These observations suggest that disease-amplifying macrophages can produce multiple adverse effects in the affected nerves which likely funnel down to common clinical features. Surprisingly, treatment of mouse models mimicking Charcot-Marie-Tooth type 1A neuropathy also caused macrophage blockade, but did not result in neuropathic or clinical improvements

    Digital flood-inundation maps for a 9-mile reach of the St. Marys River that extends from South Anthony Boulevard to Main Street at Fort Wayne, Indiana, were created by the U.S. Geological Survey (USGS) in cooperation with the City of Fort Wayne. The inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site, depict estimates of the areal extent of flooding corresponding to selected water levels (stages) at the USGS streamgage 04182000 St. Marys River near Fort Wayne, Ind. Current conditions at the USGS streamgages in Indiana may be obtained from the National Water Information System: Web Interface. In addition, the information has been provided to the National Weather Service (NWS) for incorporation into their Advanced Hydrologic Prediction Service (AHPS) flood warning system. The NWS forecasts flood hydrographs at many places that are often collocated at USGS streamgages. That forecasted peak-stage information, also available on the Internet, may be used in conjunction with the maps developed in this study to show predicted areas of flood inundation. In this study, water-surface profiles were simulated for the stream reach by means of a hydraulic one-dimensional step-backwater model. The model was calibrated using the most current stage-discharge relation at the USGS streamgage 04182000 St. Marys River near Fort Wayne, Ind. The hydraulic model was then used to simulate 11 water-surface profiles for flood stages at 1-ft intervals referenced to the streamgage datum and ranging from bankfull to approximately the highest recorded water level at the streamgage. The simulated water-surface profiles were then combined with a geographic information system digital elevation model (derived from Light Detection and Ranging (LiDAR) data) in order to delineate the area flooded at each water level. A flood inundation map was generated for each water-surface profile stage (11 maps in all) so that for any given flood stage users will be

    Charcot-Marie-Tooth disease (CMTD) is a hereditary peripheral neuropathy and is characterized by progressive muscle atrophy and motor-sensory disorders in all 4 limbs. Most reports have indicated that major challenges with general anesthetic administration in CMTD patients are the appropriate use of nondepolarizing muscle relaxants and preparation for malignant hyperthermia in neuromuscular disease. Moderate sedation may be associated with the same complications as those of general anesthesia, as well as dysfunction of the autonomic nervous system, reduced perioperative respiratory function, difficulty in positioning, and sensitivity to intravenous anesthetic agents. We decided to use intravenous sedation in a CMTD patient and administered midazolam initially and propofol continuously, with total doses of 1.5 mg and 300 mg, respectively. Anesthesia was completed in 3 hours and 30 minutes without adverse events. We suggest that dental anesthetic treatment with propofol and midazolam may be effective for patients with CMTD.

    The charged particle spectrum for nuclei from protons to neon, (charge Z=10) was observed during the cruise phase and orbit around Mars by the MARIE charged particle spectrometer on the Odyssey spacecraft. The cruise data were taken between April 23, 2001 and mid-August 2001. The Mars orbit data were taken March 5, 2002 through May 2002 and are scheduled to continue until August 2004. Charge peaks are clearly separated for charges up to Z=10. Especially prominent are the carbon and oxygen peaks, with boron and nitrogen also clearly visible. Although heavy ions are much less abundant than protons in the cosmic ray environment, it is important to determine their abundances because their ionization energy losses (proportional to Z2) are far more dangerous to humans and to instruments. Thus the higher charged nuclei make a significant contribution to dose and dose equivalent received in space. Results of the charged particle spectrum measurements will be reported.

    Ultrasound is emerging as a useful tool for evaluation of neuromuscular conditions, because it can provide high-resolution anatomic information to complement electrodiagnostic data. There have been few studies in which ultrasound was used to assess the peripheral nerves of individuals with Charcot-Marie-Tooth (CMT) disease and none involving CMT type 1B. In this study we compared nerve cross-sectional area in individuals from a single large family with CMT 1B with normal, healthy controls. We also assessed for cranial nerve enlargement in those with CMT 1B with cranial neuropathies compared to those with CMT 1B without cranial neuropathies. Individuals with CMT 1B have significantly larger median and vagus nerves than healthy controls, but no difference was seen in cranial nerve size between those with versus those without cranial neuropathies. This is the first study to characterize the ultrasonographic findings in the peripheral nerves of individuals with CMT 1B.

    This article addresses the Maltese traditional family, taking St. Mary's (Qrendi) as a test case. It results that couples married in their early twenties, while a high proportion of men and women never married at all. Marriage was not popular so that one-fifth of all marriages were remarriages. Very few widows remarried and it was only for some economic reason that they sought another man. There is no evidence though that a high rate of celibacy resulted in flagrant promiscuity even if there is evidence that the Qrendin were not so particular about their sex life. No birth control was practiced within marriage and children followed one another regularly. This brings into relief the parents' unconcern for their offspring's future as well as the inferior status of women because husbands made their wives several offspring. Relations between the spouses were poor so that dissatisfied couples went their own ways.

    To date, there is no approved pharmacologic treatment for any form of Charcot-Marie-Tooth disease (CMT). However, some clinical or preclinical trials for CMT1A have been undertaken, for example Neurotrophin-3, PXT3003, and neuregulin-1. Gene therapy for CMT1X, CMT2F and Giant axonal neuropathy using animal model or culture cells have been reported with some interesting results. Stem cell research for example iPS cells derived from patients with CMT2A or CMT2E, is being conducted to clarify the mechanism of CMT and find therapeutic clues. The development of new surrogate markers for clinical trials is also needed. Additionally, steps should be taken to improve the quality of life of patients with CMT, including pain control and life style enhancement.

    The discovery in 1991 that chromosome 17p12 duplication is associated with Charcot-Marie-Tooth (CMT) disease marked the beginning of an era of molecular insight into this disorder, which encompasses the peripheral motor and sensory neuropathies. A mere two decades later, over 40 subtypes of CMT have been molecularly defined and many have been extensively studied in vitro and in animal models, providing the framework for a more comprehensive understanding of the biological pathways dictating myelination, axonal dynamics, and axon-glia interactions. The advent of next-generation sequencing technologies offers opportunities in both research and clinical settings for gene discovery, further molecular understanding and diagnosis, and calls for modifications of the existing algorithms guiding genetic testing. Although treatment is mainly supportive at this time, advances in this field are anticipated as the molecular basis of CMT is unraveled.

    X-linked Charcot-Marie-Tooth disease (CMTX) is the second common genetic variant of CMT. CMTX type 1 causes 90% of CMTX. The most important clinical features of CMTX are similar with other types of CMT; however, a few patients get the central nervous system involved with or without white matter lesions; males are more severely and earlier affected than females. In this review, the authors focus on the origin and classification of CMTX, the central nervous system manifestations of CMTX1, the possible mechanism by which GJB1 mutations cause CMT1X, and the emerging therapeutic strategies for CMTX. Moreover, several cases are presented to illustrate the central nervous system manifestations.

    Echo data hiding is an important approach of audio information hiding in the time domain. But it has serious disadvantages, such as low capacity, relatively low restoration rate and the possibility of malicious tampering, etc. In this paper, based on the simulation analysis of the relation between the detection performance (restoration rate) and the key parameters, we proposed a novel echo M-ary data hiding system using backward and forward echo kernel to improve the weak points of conventional echo data hiding. The subjective quality of the stego audio and the original audio has no evident difference and reach a good hiding effects. The capacity is increased from 50bit/s to 250 bit/s and the restoration rate reaches to 99% for speech in 8000Hz sample frequency, 16 bits quantization, i. e., M=32. And then, we also simulated the robustness performances, such as against adding white noise, resample, filtering, ADPCM compression, etc.

    One of the primary concerns prior to human exploration of Mars is the need to accurately characterize the charged particle radiation environment both for the surface stay, and for the transit period to and from the planet. The Odyssey spacecraft, currently in Mars orbit includes a charged particle radiation detector, MARIE, which can measure particle fluxes with energies above approx. 30 MeV and charges between 1 and 10. Two classes of particles are of particular interest: the Galactic Cosmic Rays, (GCR), and those charged particles associated with Solar Particle Events, (SPE). The GCR are present continuously throughout the solar activity cycle, and their numbers vary inversely with the level of solar activity. They are characteristically more energetic than those particles originating from solar activity, and hence less influences by the solar magnetic field.

    Periaxin (PRX) plays a significant role in the myelination of the peripheral nerve. To date, seven non-sense or frameshift PRX mutations have been reported in six pedigrees with Dejerine-Sottas neuropathy or severe Charcot-Marie-Tooth neuropathy (CMT). We detected a PRX mutation in three patients in the screening of 66 Japanese demyelinating CMT patients who were negative for the gene mutation causing dominant or X-linked demyelinating CMT. Three unrelated patients were homozygous for a novel R1070X mutation and presented early-onset but slowly progressive distal motor and sensory neuropathies. Mutations lacking the carboxyl-terminal acidic domain may show loss-of-function effects and cause severe demyelinating CMT. PMID:15197604

    Great advances have been made in understanding the molecular basis of Charcot-Marie-Tooth disease (CMT) and related neuropathies, namely Dejerine-Sottas disease (DSD), hereditary neuropathy with liability to pressure palsies (HNPP) and congenital hypomyelination (CH). The number of newly uncovered mutations and identified genetic loci is rapidly increasing, and, as a consequence, the classification of these disorders is becoming more complicated. Molecular genetics, animal models, and transfected cell studies are shedding light on function and dysfunction of proteins involved in hereditary myelinopathies-peripheral myelin protein 22 (PMP22), myelin protein zero (PO), connexin 32 (Cx32), and early growth response 2 (EGR2). Gene dosage effect, loss of function, gain of toxic function, and dominant negative effect are possible mechanisms whereby different gene mutations may exert their detrimental action on peripheral nerves. A tentative rational approach to clinical and molecular diagnosis based on genotype-phenotype correlation analysis is described. PMID:10514227

    The diagnosis of Charcot-Marie-Tooth disease (CMT) and related neuropathies (e. g. Déjèrine-Sottas disease; hereditary neuropathy with liability to pressure palsies) appears to be easy. However, the incredible advances in molecular genetics have greatly complicated the classification of these disorders, and the proper diagnosis of the CMT subtype may be important for correct genetic counselling and prognosis. Moreover, these diseases may be confused with potentially treatable acquired and inherited neuropathies, such as dysimmune neuropathies, familial amyloid polyneuropathy, and Refsum's disease. A number of clinical, laboratory, electrophysiological, morphological and neuroradiological features that may help in the diagnostic process are reviewed in the present paper. DNA investigations are fundamental but need to be properly addressed. Currently, great interest is focused on the role of the immune system in hereditary neuropathies, and surprising findings are coming from research on animal models. PMID:15221625

    Throughout the ages, literary works have expressed fears and expectations generated by scientific discoveries and have portrayed images and myths about science itself. Several parameters can contribute to these representations of science, including the culture and social class to which the authors of these works belong. We also cannot deny the influence of gender, as due to the fact that the male sphere of action dominates science, male or female authoring can determine a peculiar characterization of the scientific world. In the present work, through a comparative analysis of two important literary works from the 19th century, Frankenstein, by Mary Shelley, and Dracula, by Bram Stoker, the issues concerning the view of science and their relation to gender are highlighted. While Shelley, as a woman, apart from the scientific world, reveals in Frankenstein all her distrust about it, Stoker, the model of a Victorian man, expresses in Dracula his total trust in science.

    Ostwald, J.

    1992-09-01

    The Mary Valley manganese deposits exhibit mineralogy and textures characteristic of at least four parageneses. The deposits consist mainly of isolated occurrences of braunite, together with a number of lower and higher valency manganese oxides, and manganese silicates, in bedded radiolarian cherts and jaspers of Permian age. The parageneses are: (a) Braunite — quartz (primary), (b) Braunite — hausmannite — spessartine — tephroite — quartz (metamorphic). (c) Hydrated manganese silicates — barite — braunite — hausmannite (hydrothermal veins), (d) Tetravalent manganese oxides (pyrolusite, cryptomelane, manjiroite, nsutite) (supergene). The primary mineralisation is interpreted as the result of the geochemical separation of Mn from Fe in a submarine exhalative system, and the precipitation of Mn as oxide within bedded radiolarian oozes and submarine lavas. During diagenesis this hydrothermal manganese oxide reacted with silica to produce primary braunite. The later geological of evolution of this volcanogenicsedimentary deposit involved metamorphism, hydrothermal veining by remobilised manganese, and supergene enrichment.

    Nitrous oxide is routinely administered to children and adults with Charcot-Marie-Tooth disease (CMT) as an anaesthetic for procedures such as nerve conduction studies and maintenance for general anaesthesia. However it is listed as a 'moderate to significant' risk of potential toxicity and worsening neuropathy in people with CMT by the CMT Association (USA), CMT Association of Australia, CMT International (Canada) and CMT United Kingdom. We performed a systematic review focussing on the use of nitrous oxide in patients with CMT to help clarify its safety. This identified 11 studies reporting 41 exposures to therapeutically inhaled nitrous oxide as maintenance for general anaesthesia with no reports of adverse effects or worsening of CMT neuropathy. In the absence of a single case in the literature reporting worsening neuropathy in CMT patients receiving nitrous oxide, this review provides good evidence that nitrous oxide should be considered a safe agent for use in children and adults with CMT.

    The Fosdick Mountains form an E-W trending migmatite dome in the northern Ford Ranges of Marie Byrd Land, Antarctica. Pervasively folded migmatites derived from lower Paleozoic greywacke and middle Paleozoic plutonic rocks constitute the dome. New field research documents a transition from melt-present to solid-state deformation across the south flank of the dome, and a mylonitic shear zone mapped for 30 km between Mt. Iphigene and Mt Richardson. Kinematic shear sense is dextral normal oblique, with top-to-the-SW and -WSW transport. A U-Pb age of 107 Ma, from a leucosome-filled extensional shear band, provides a meltpresent deformation age, and a U-Pb age of 96 Ma, from a crosscutting granitic dike, gives a lower age limit for deformation. The shear zone, here named the South Fosdick detachment zone, forms the south flank of the migmatite dome and was in part responsible for the exhumation of mid-crustal rocks.

    In the early part of the 20th century, the pioneers of radioactivity research, led by Marie Curie, Ernest Rutherford and Stefan Meyer, formed a Commission internationale des étalons de radium. The Commission made arrangements for the preparation and intercomparisons of the international standards of radium, which were identified as the Paris standard and the Vienna standard. Otto Hönigschmid from Vienna prepared a first set of international secondary standards in 1912 and a second set in 1934. In both instances, these secondary standards were compared by gamma-ray measurements with the Paris and Vienna standards. The usage of these international standards of radium in the 20th century is described.

    The authors present an overview of the major concepts and contributions of Mary Parker Follett to the development of social work management theory, past and present. The case is made for Follett to be afforded a more visible role in the profession's understanding and teaching of modern management theory and practice. The authors show how Follett's work served as an important bridge between changing eras in management thought, specifically as related to scientific management and the subsequent human relations models. Even after six decades, Follett's work, in its timelessness and timeliness, remains contemporary, for it is rooted in her keen ability to grasp the complexities inherent in the human services enterprise, and thus it continues to inform one's understanding and behavior within the organizational context.

    Months after a 7.0 magnitude earthquake hit Port-au-Prince, Haiti, over one million remain homeless and living in spontaneous internally displaced person (IDP) camps. Billions of dollars from aid organizations and government agencies have been pledged toward the relief effort, yet many basic human needs, including food, shelter, and sanitation, continue to be unmet. The Sphere Project, "Humanitarian Charter and Minimum Standards in Disaster Response," identifies the minimum standards to be attained in disaster response. From a human rights perspective and utilizing key indicators from the Sphere Project as benchmarks, this article reports on an assessment of the living conditions approximately 12 weeks after the earthquake in Parc Jean Marie Vincent, a spontaneous IDP camp in Port-au-Prince. A stratified random sample of households in the camp, proportionate to the number of families living in each sector, was selected. Interview questions were designed to serve as "key indicators" for the Sphere Project minimum standards. A total of 486 interviews were completed, representing approximately 5% of households in each of the five sectors of the camp. Our assessment identified the relative achievements and shortcomings in the provision of relief services in Parc Jean Marie Vincent. At the time of this survey, the Sphere Project minimum standards for access to health care and quantity of water per person per day were being met. Food, shelter, sanitation, and security were below minimum accepted standard and of major concern. The formal assessment reported here was completed by September 2010, and is necessarily limited to conditions in Haiti before the cholera outbreak in October.

    The U.S. Geological Survey is using Landsat imagery from the early 1970s and mid- to late 1980s/early 1990s to analyze glaciological features, compile a glacier inventory, measure surface velocities of outlet glaciers, ice streams and ice shelves, determine coastline change and calculate the area and volume of iceberg calving in Antarctica. Ice-surface velocities in Marie Byrd and Ellsworth Lands, West Antarctica, range from the fast-moving Thwaites, Pine Island, Land and DeVicq Glaciers to the slower-moving ice shelves. The average ice-front velocity during the time interval of Landsat imagery, for the faster-moving outlet glaciers, was 2.9 km a-1 for Thwaites Glacier, 2.4 km a-1 for Pine Island Glacier, 2.0 km a-1 for Land Glacier and 1.4 km a-1 for DeVicq Glacier. Evaluation of coastal change from the early 1970s to the early 1990s shows advance of the floating ice front in some coastal areas and recession in others, with an overall small average advance in the entire coastal study area, but no major trend towards advance or retreat. Comparison of average ice-surface velocities with changes in the ice front has yielded estimates of iceberg calving. The total iceberg calving from the Marie Byrd Land and Ellsworth Land coasts during the study period was greater than 8500 km2 (estimated volume of about 2400 km3) or an average of about 550 km2 a-1 (more than 150 km3 a-1). Almost 70% of this discharge is contributed by Thwaites and Pine Island Glaciers.

    2016-03-01

    Since the beginning of the last century, genetic research has been preoccupied with the dosage compensation question: What mechanism controls equal expression of chromosome X genes between females and males? In the 1950s, many discoveries occurred in the field of cytogenetics related to the sex chromatin of female mammals. Concomitantly, genetic information accumulated with regard to expression patterns of X-linked genes in female mice and the expression effect of translocations between chromosome X and autosomes. In addition, many case reports were published about families with sex-linked diseases. The lately deceased scientist Mary F. Lyon suggested a unifying theory of these findings. In her articles "Gene action in the X-chromosome of the mouse (Mus musculus L.T in 1961, and "Sex chromatin and gene action in the mammalian X-chromosome" in 1962, she suggested that: (1) the heteropyknotic chromosome X was genetically inactivated, (2) the inactivated chromosome X could be either paternal or maternal in origin in different cells of the same animal, and (3) the inactivation occurred early in embryonic development. This theory led to an immediate breakthrough in understanding the basic mechanisms responsible for X-linked diseases and solved many unexplained case studies. Moreover, the inquiry of the mechanism of the phenomenon promoted scientific understanding of a wide range of areas in molecular biology such as DNA methylation, the silencing mechanism by XIST, histone modifications, DNA replication timing and more. The current article deals with some biographical details about Mary F. Lyon, the background of her theory, her historical articles and the development of the field since. PMID:27305745

    We sampled benthos from the St. Marys River in May 1974 and May 1975 to determine visibly the occurrence of sorpted oil and the distribution of nymphs of the burrowing mayfly Hexagenia in the bottom of the Lake George and Lake Nicolet channels. Results of our survey showed that, between 1967 and 1974-75, the occurrence of oil in the substrate of the Lake George Channel had advanced from 16 km to 30 km downstream from the point where oil is discharged at Sault Ste. Marie, Ontario. Absence or low densities of nymphs coincided with the presence of oil in the sediments. In the Lake Nicolet Channel, evidence of oil pollution was meager and the density of Hexagenia nymphs was generally high.

    As the sciences advanced rapidly in the modern European world, outstanding achievements have been made in medicine, chemistry, biology, physiology, physics and others, which have been co-influencing each of the scientific disciplines. Accordingly, such medical and scientific phenomena began to be reflected in novels. In particular, Mary Shelley's Frankenstein includes the diverse aspects of the change and development in the medicine and science. Associated with medical and scientific information reflected in Frankenstein and Frankenstein's experiments in the text, accordingly, this research will investigate the aspects of medical and scientific development taking place in the nineteenth century in three ways. First, the medical and scientific development of the nineteenth century has been reviewed by summerizing both the information of alchemy in which Frankenstein shows his interest and the new science in general that M. Waldman introduces in the text. Second, the actual features of medical and scientific development have been examined through some examples of the experimental methods that M. Waldman implicitly uttered to Frankenstein. Third, it has been checked how the medical and scientific development is related to the main issues of mechanism and vitalism which can be explained as principles of life. Even though this research deals with the developmental process of medicine & science and origin & principles of life implied in Mary Shelley's Frankenstein, its significance is that it is the interdisciplinary research focussing on how deeply medical and scientific discourse of Mary Shelley's period has been imbedded in the nineteenth century novel.

    As part of the International Polar Year in Antarctica, 37 seismic stations have been installed across West Antarctica as part of the Polar Earth Observing Network (POLENET). 23 stations form a sparse backbone network of which 21 are co-located on rock sites with a network of continuously recording GPS stations. The remaining 14 stations, in conjunction with 2 backbone stations, form a seismic transect extending from the Ellsworth Mountains across the West Antarctic Rift System (WARS) and into Marie Byrd Land. Here we present preliminary P and S wave velocity models of the upper mantle from regional body wave tomography using P and S travel times from teleseismic events recorded by the seismic transect during the first year (2009-2010) of deployment. Preliminary P wave velocity models consisting of ~3,000 ray paths from 266 events indicate that the upper mantle beneath the Whitmore Mountains is seismically faster than the upper mantle beneath Marie Byrd Land and the WARS. Furthermore, we observe two substantial upper mantle low velocity zones located beneath Marie Byrd Land and near the southern boundary of the WARS.

    We aimed to investigate the relationship between neurological compromise, respiratory parameters in wakefulness and in sleep, physiology, and morphology of phrenic nerves in patients with Charcot-Marie-Tooth disease type 1A (CMT1A). Sixteen patients with CMT1A were evaluated by spirometry, maximal expiratory and maximal inspiratory pressures (MEP, MIP), polysomnography, phrenic nerve compound muscle action potential (CMAP), and ultrasonography (roots C3,C4,C5 and phrenic nerves). Clinical disability was measured with Charcot-Marie-Tooth neuropathy score (CMT-NS; range 0-36). Two control groups, comprising 30 individuals matched for age, sex, and body mass index, were used for comparison. Ten patients were female (62%), mean age was 37.88 years (range 24-76); and CMT-NS range was 7-34. MIP was reduced in five (31%) and MEP in 12 patients (75%), although only one had restrictive respiratory dysfunction in spirometry. Apnoea-hypopnea index (AHI) was significantly higher in patients (12.01 ± 11.57/h × 5.89 ± 8.36/h; p value = 0.05) and increased in REM sleep compared with NREM (9.94 ± 10.96/h × 19.13 ± 19.93/h; p value = 0.01). There were significant correlations between CMT-NS and AHI (Pearson = 0.69; p value = 0.03); CMT-NS and MIP (Pearson = -0.691, p value = 0.003); and CMT-NS and MEP (Pearson = -0.603, p value = 0.013). Also, AHI showed negative correlation with MIP (Pearson = -0.52, p value = 0.036) and MEP (Pearson = -0.55, p value = 0.026). Phrenic nerves were enlarged in ultrasonography in all patients and presented significant correlations with CMAPs (right: Pearson = -0.554, p value = 0.026; left: Pearson = -0.558, p value = 0.025). We suggest that axonal degeneration of nerves directed to muscles of respiration might explain the high prevalence of respiratory weakness in patients with CMT1A. Clinical manifestations are frequent during sleep, where the diaphragm alone can only partially surpass the overload in breathing apparatus. PMID:25761374

    John Bowlby is generally regarded as the founder of attachment theory, with the help of Mary Ainsworth. Through her Uganda and Baltimore studies Ainsworth provided empirical evidence for attachment theory, and she contributed the notion of the secure base and exploratory behavior, the Strange Situation Procedure and its classification system, and the notion of maternal sensitivity. On closer scrutiny, many of these contributions appear to be heavily influenced by William Blatz and his security theory. Even though Blatz's influence on Ainsworth has been generally acknowledged, this article, partly based on understudied correspondence from several personal archives, is the first to show which specific parts of attachment theory can be traced back directly to Blatz and his security theory. When Ainsworth started working with Bowlby in the 1950s, around the time he turned to evolutionary theory for an explanation of his findings, she integrated much of Blatzian security theory into Bowlby's theory in the making and used her theoretical and practical experience to enrich attachment theory. Even though Blatz is hardly mentioned nowadays, several of his ideas live on in attachment theory.

    Charcot-Marie-Tooth disease type 1A (CMT1A), the most frequent form of CMT, is caused by a 1.5 Mb duplication on the short arm of chromosome 17. Patients with CMT1A typically have slowed nerve conduction velocities (NCVs), reduced compound motor and sensory nerve action potentials (CMAPs and SNAPs), distal weakness, sensory loss and decreased reflexes. In order to understand further the molecular pathogenesis of CMT1A, as well as to determine which features correlate with neurological dysfunction and might thus be amenable to treatment, we evaluated the clinical and electrophysiological phenotype in 42 patients with CMT1A. In these patients, muscle weakness, CMAP amplitudes and motor unit number estimates correlated with clinical disability, while motor NCV did not. In addition, loss of joint position sense and reduction in SNAP amplitudes also correlated with clinical disability, while sensory NCV did not. Taken together, these data strongly support the hypothesis that neurological dysfunction and clinical disability in CMT1A are caused by loss or damage to large calibre motor and sensory axons. Therapeutic approaches to ameliorate disability in CMT1A, as in amyotrophic lateral sclerosis and other neurodegenerative diseases, should thus be directed towards preventing axonal degeneration and/or promoting axonal regeneration.

    P0 glycoprotein is an abundant product of terminal differentiation in myelinating Schwann cells. The mutant P0S63del causes Charcot-Marie-Tooth 1B neuropathy in humans, and a very similar demyelinating neuropathy in transgenic mice. P0S63del is retained in the endoplasmic reticulum of Schwann cells, where it promotes unfolded protein stress and elicits an unfolded protein response (UPR) associated with translational attenuation. Ablation of Chop, a UPR mediator, from S63del mice completely rescues their motor deficit and reduces active demyelination by half. Here, we show that Gadd34 is a detrimental effector of CHOP that reactivates translation too aggressively in myelinating Schwann cells. Genetic or pharmacological limitation of Gadd34 function moderates translational reactivation, improves myelination in S63del nerves, and reduces accumulation of P0S63del in the ER. Resetting translational homeostasis may provide a therapeutic strategy in tissues impaired by misfolded proteins that are synthesized during terminal differentiation.

    The Airborne Imaging Spectrometer (AIS) was flown over granitic, volcanic, and calc-silicate terrain around the Mary Kathleen Uranium Mine in Queensland, in a test of its mineralocial mapping capabilities. An analysis strategy and restoration and enhancement techniques were developed to process the 128 band AIS data. A preliminary analysis of one of three AIS flight lines shows that the data contains considerable spectral variation but that it is also contaminated by second-order leakage of radiation from the near-infrared region. This makes the recognition of expected spectral absorption shapes very difficult. The effect appears worst in terrains containing considerable vegetation. Techniques that try to predict this supplementary radiation coupled with the log residual analytical technique show that expected mineral absorption spectra can be derived. The techniques suggest that with additional refinement correction procedures, the Australian AIS data may be revised. Application of the log residual analysis method has proved very successful on the cuprite, Nevada data set, and for highlighting the alunite, linite, and SiOH mineralogy.

    Charcot-Marie-Tooth type 1A (CMT1A) neuropathies linked to the misexpression of peripheral myelin protein 22 (PMP22) are progressive demyelinating disorders of the peripheral nervous system. In this study we asked whether dietary restriction by intermittent fasting (IF) could alleviate the neuropathic phenotype in the Trembler J (TrJ) mouse model of CMT1A. Our results show that neuropathic mice kept on a five month long IF regimen had improved locomotor performance compared to ad libitum (AL) fed littermates. The functional benefits of this dietary intervention are associated with an increased expression of myelin proteins combined with a thicker myelin sheath, less redundant basal lamina, and a reduction in aberrant Schwann cell proliferation. These morphological improvements are accompanied by a decrease in PMP22 protein aggregates, and enhanced expression of cytosolic chaperones and constituents of the autophagy-lysosomal pathway. These results indicate that dietary restriction is beneficial for peripheral nerve function in TrJ neuropathic mice, as it promotes the maintenance of locomotor performance. PMID:19320048

    Background. The aim of this study was to evaluate the oral health status of temporomandibular disorders (TMD) and bruxism, as well as to measure masticatory performance of subjects with Charcot-Marie-Tooth type 2 (CMT2). Methods and Results. The average number of decayed, missing, and filled teeth (DMFT) for both groups, control (CG) and CMT2, was considered low (CG = 2.46; CMT2 = 1.85, P = 0.227). The OHIP-14 score was considered low (CG = 2.86, CMT2 = 5.83, P = 0.899). The prevalence of self-reported TMD was 33.3% and 38.9% (P = 0.718) in CG and CMT2 respectively and for self-reported bruxism was 4.8% (CG) and 22.2% (CMT2), without significant difference between groups (P = 0.162). The most common clinical sign of TMD was masseter (CG = 38.1%; CMT2 = 66.7%) and temporalis (CG = 19.0%; GCMT2 = 33.3%) muscle pain. The geometric mean diameter (GMD) was not significantly different between groups (CG = 4369; CMT2 = 4627, P = 0.157). Conclusion. We conclude that the CMT2 disease did not negatively have influence either on oral health status in the presence and severity of TMD and bruxism or on masticatory performance. PMID:24391462

    The aim of this study was to determine the clinical features and frequencies of genetic subtypes in a series of patients with Charcot-Marie-Tooth (CMT) disease from Eastern China. Patients were divided into three subtypes, CMT1, CMT2 and hereditary neuropathy with liability to pressure palsy (HNPP), according to their electrophysiological manifestations. Multiplex ligation-dependent probe analysis (MLPA) was performed to detect duplications/deletions in the PMP22 gene. The coding regions and splice sites of the GJB1, MPZ, MFN2 and GDAP-1 genes were determined by direct sequencing. Among the 148 patients in the study, 37.2% of the cases had mutations in genes assessed. The mutation detection rate was higher in patients with family histories than in spontaneous cases. PMP22 duplication (13.5%) was predominant in this group of patients, followed by PMP22 deletion (11.5%), and point mutations in GJB1 (8.8%), MPZ (2.0%) and MFN2 (0.7%). Three novel mutations (c.151T>C and c.310 A>G in GJB1 and c.1516 C>G in MFN2) were detected. A small deletion in PMP22 exon 4 was detected in a patient with severe CMT1. Genetic tests have great value in CMT patients with family histories. The frequency of PMP22 duplications was lower in Asian patients than in others. We suggest that genetic testing strategies in CMT patients should be primarily based on electromyography data.

    Charcot-Marie-Tooth (CMT) disease is a well-known neural or spinal type of muscular atrophy. It is the most familiar disease within a group of conditions called Hereditary Motor and Sensory Neuropathies (HMSN). The disease was discovered by three scientists several years ago. Several genes are involved as the causative agents for the disease. Hundreds of causative mutations have been found and research work for the identification of a novel locus and for the treatment of CMT1A is going on. This review article was planned to gather information on CMT disease and updates on its treatment.National Center for Biotechnology Information (NCBI) and PubMed were searched for data retrieval. Molgen database, which is the exclusive site for CMT mutation, was the other source of articles. Different aspects of the CMT disease were compared.Advancements in the finding of the causative gene, discovery of the novel Loci are the current issues in this regard.CMT disease is incurable, but researchers are trying to get some benefits from different natural compounds and several therapeutic agents.Various groups are working on the treatment projects of CMT1A. Major step forward in CMT research was taken in 2004 when ascorbic acid was used for transgenic mice treatment. Gene therapy for constant neurotrophin-3 (NT- 3) delivery by secretion by muscle cells for the CMT1A is also one of the possible treatments under trial.

    Charcot-Marie-Tooth disease (CMT) is the most commonly inherited peripheral neuropathy. CMT disease signs include distal limb neuropathy, abnormal gait, sensory defects, and deafness. We generated a novel line of CMT2E mice expressing hNF-L(E397K), which displayed muscle atrophy of the lower limbs without denervation, proximal reduction in large caliber axons, and decreased nerve conduction velocity. In this study, we challenged wild type, hNF-L and hNF-L(E397K) mice with crush injury to the sciatic nerve. We analyzed functional recovery by measuring toe spread and analyzed gait using the Catwalk system. hNF-L(E397K) mice demonstrated reduced recovery from nerve injury consistent with increased susceptibility to neuropathy observed in CMT patients. In addition, hNF-L(E397K) developed a permanent reduction in their ability to weight bear, increased mechanical allodynia, and premature gait shift in the injured limb, which led to increasingly disrupted interlimb coordination in hNF-L(E397K). Exacerbation of neuropathy after injury and identification of gait alterations in combination with previously described pathology suggests that hNF-L(E397K) mice recapitulate many of clinical signs associated with CMT2. Therefore, hNF-L(E397K) mice provide a model for determining the efficacy of novel therapies.

    The charged particle spectrum for nuclei from protons to neon, (charge Z=10) was observed during the cruise phase and orbit around Mars by the MARIE charged particle spectrometer on the Odyssey spacecraft. The cruise data were taken between April 23, 2001 and mid-August 2001. The Mars orbit data were taken March 5, 2002 through May 2002 and are scheduled to continue until August 2004. Charge peaks are clearly separated for charges up to Z=10. Especially prominent are the carbon and oxygen peaks, with boron and nitrogen also clearly visible. Although heavy ions are much less abundant than protons in the cosmic ray environment, it is important to determine their abundances because their ionization energy losses (proportional to Z2) are far more dangerous to humans and to instruments. Thus the higher charged nuclei make a significant contribution to dose and dose equivalent received in space. Results of the charged particle spectrum measurements will be reported. c2003 COSPAR.

    Conservation Action Planning (CAP) is an adaptive management planning process refined by The Nature Conservancy (TNC) and embraced worldwide as the Open Standards for the Practice of Conservation. The CAP process facilitates open, multi-institutional collaboration on a common conservation agenda through organized actions and quantified results. While specifically designed for conservation efforts, the framework is adaptable and flexible to multiple scales and can be used for any collaborative planning effort. The CAP framework addresses inception; design and development of goals, measures, and strategies; and plan implementation and evaluation. The specific components of the CAP include defining the project scope and conservation targets; assessing the ecological viability; ascertaining threats and surrounding situation; identifying opportunities and designing strategies for action; and implementing actions and monitoring results. In 2007, TNC and a multidisciplinary graduate student team from the University of Michigan's School of Natural Resources and Environment initiated a CAP for the St. Marys River, the connecting channel between Lake Superior and Lake Huron, and its local watershed. The students not only gained experience in conservation planning, but also learned lessons that notably benefited the CAP process and were valuable for any successful collaborative effort—a dedicated core team improved product quality, accelerated the timeline, and provided necessary support for ongoing efforts; an academic approach in preparation for engagement in the planning process brought applicable scientific research to the forefront, enhanced workshop facilitation, and improved stakeholder participation; and early and continuous interactions with regional stakeholders improved cooperation and built a supportive network for collaboration.

  8. An encounter between psychology and religion: humanistic psychology and the Immaculate Heart of Mary nuns.

    In the 1960s, humanistic psychology changed the relationship between psychology and religion by actively asserting the value of individual experience and self-expression. This was particularly evident in the encounter group movement. Beginning in 1967, Carl Rogers conducted a series of encounter groups, in order to promote "self-directed change in an educational system," for the Sisters of the Immaculate Heart of Mary, a religious order in California running an educational system. William Coulson, one of Rogers's associates in the project, later charged that the encounter groups undermined the religious order and played a major contributing part in the breakup of the order in 1970. The article examines these charges, situating the incident within the context of the changes occurring in religious life and in psychology in the 1960s. The article concludes that an already existing conflict the nuns had with the conservative Cardinal McIntyre of Los Angeles led to the departure of some 300 nuns from the order, who began the Immaculate Heart Community, an organization existing today. Nevertheless, encounter groups proved to be a psychological technology that helped to infuse a modern psychological--specifically, a humanistic psychological--perspective into contemporary religious life.

    Environmental and breathing-zone samples were analyzed for polynuclear aromatic hydrocarbons (PAH), total particulates, and respirable free silica at the Airco Company (SIC-3624), Saint Marys, Pennsylvania in January, 1984. The evaluation was requested confidentially because of concern over exposures to soot, coal tar pitch volatiles, and sand in the car bottom and sagger bake operations. Forty-three employees were interviewed. Two of 19 total particulate samples exceeded the OSHA standard of 15 milligrams per cubic meter (mg/m3), 17.3 and 32.7 mg/m3. Benzene soluble fractions ranged from 0.5 to 5.0 mg/m3. The OSHA standard for benzene soluble fractions is 0.2 mg/m3. Two of seven samples of silica were above the limit of detection, 0.09 and 0.06 mg/m3. In bulk samples, the benzene soluble fractions ranged from 0.44 to 860 mg/gram and the PAH content from 0 to 26,124 micrograms per gram. Employees working in the bake areas reported a significant excess incidence of symptoms such as skin, nose and eye irritation, cough, sore or dry throat, chest tightness, and breathing difficulty. The authors conclude that a health hazard exists at the facility. Recommendations include enclosing vehicles used in moving electrodes, cleaning up spilled dust, and controlling fumes emitted from the sagger kilns.

    Long-term surveys are useful in understanding trends in connecting channel fish communities; a gill net assessment in the Saint Marys River performed periodically since 1975 is the most comprehensive connecting channels sampling program within the Laurentian Great Lakes. We assessed efficiency of that survey, with intent to inform development of assessments at other connecting channels. We evaluated trends in community composition, effort versus estimates of species richness, ability to detect abundance changes for four species, and effects of subsampling yellow perch catches on size and age-structure metrics. Efficiency analysis revealed low power to detect changes in species abundance, whereas reduced effort could be considered to index species richness. Subsampling simulations indicated that subsampling would have allowed reliable estimates of yellow perch (Perca flavescens) population structure, while greatly reducing the number of fish that were assigned ages. Analyses of statistical power and efficiency of current sampling protocols are useful for managers collecting and using these types of data as well as for the development of new monitoring programs. Our approach provides insight into whether survey goals and objectives were being attained and can help evaluate ability of surveys to answer novel questions that arise as management strategies are refined.

    The orthopedic manifestations in patients with Charcot-Marie-Tooth disease include deformity and dysfunction of the extremities and spine. Conservative treatment is the first choice. Orthosis and rehabilitation can improve function, and are important for the prevention of joint contractures. Foot problems are most commonly observed and require surgical treatment. Foot deformities include pes cavus, cavovarus, claw toes, or drop foot. Single or combined surgeries selected for soft tissues are plantar release, tendon transfer, or Achilles tendon lengthening, and those for bones are osteotomies and joint fusions. The upper limb initially demonstrates loss of power of the intrinsic hand muscles followed by symmetrical atrophy of the forearm muscle groups. The typical hand deformity is claw hand. Tendon transfer, joint fusion, soft tissue release, or nerve decompression procedures are performed for correction of hand deformities. Acetabular dysplasia in the hip joints is sometimes observed and osteotomy is selected as surgical treatment in such cases. The associated spinal deformity is scoliosis with or without kyphosis. Similar to treatment of idiopathic scoliosis, posterior spinal fusion is performed in patients with progressive spinal deformities. PMID:26764299

    Using a combination of exome sequencing and linkage analysis, we investigated an English family with two affected siblings in their 40s with recessive Charcot-Marie Tooth disease type 2 (CMT2). Compound heterozygous mutations in the immunoglobulin-helicase-μ-binding protein 2 (IGHMBP2) gene were identified. Further sequencing revealed a total of 11 CMT2 families with recessively inherited IGHMBP2 gene mutations. IGHMBP2 mutations usually lead to spinal muscular atrophy with respiratory distress type 1 (SMARD1), where most infants die before 1 year of age. The individuals with CMT2 described here, have slowly progressive weakness, wasting and sensory loss, with an axonal neuropathy typical of CMT2, but no significant respiratory compromise. Segregating IGHMBP2 mutations in CMT2 were mainly loss-of-function nonsense in the 5' region of the gene in combination with a truncating frameshift, missense, or homozygous frameshift mutations in the last exon. Mutations in CMT2 were predicted to be less aggressive as compared to those in SMARD1, and fibroblast and lymphoblast studies indicate that the IGHMBP2 protein levels are significantly higher in CMT2 than SMARD1, but lower than controls, suggesting that the clinical phenotype differences are related to the IGHMBP2 protein levels.

    Background Charcot-Marie-Tooth disease (CMT) is a clinically and genetically heterogeneous group of diseases with approximately 45 different causative genes described. The aims of this study were to determine the frequency of different genes in a large cohort of patients with CMT and devise guidelines for genetic testing in practice. Methods The genes known to cause CMT were sequenced in 1607 patients with CMT (425 patients attending an inherited neuropathy clinic and 1182 patients whose DNA was sent to the authors for genetic testing) to determine the proportion of different subtypes in a UK population. Results A molecular diagnosis was achieved in 62.6% of patients with CMT attending the inherited neuropathy clinic; in 80.4% of patients with CMT1 (demyelinating CMT) and in 25.2% of those with CMT2 (axonal CMT). Mutations or rearrangements in PMP22, GJB1, MPZ and MFN2 accounted for over 90% of the molecular diagnoses while mutations in all other genes tested were rare. Conclusion Four commonly available genes account for over 90% of all CMT molecular diagnoses; a diagnostic algorithm is proposed based on these results for use in clinical practice. Any patient with CMT without a mutation in these four genes or with an unusual phenotype should be considered for referral for an expert opinion to maximize the chance of reaching a molecular diagnosis.

    Gait analysis of people with Charcot-Marie-Tooth (CMT) disease revealed proximal adaptive gait strategies to compensate for foot drop. We previously demonstrated that hip flexor muscle fatigue can limit walking endurance. This pilot study used a single-blinded cross over design to investigate the effect of a 16-week home-based programme of resistance training on hip flexor muscle strength. Measures of walking endurance, gait speed, exertion, fatigue, and general activity were also recorded. The exercise protocol was based on American College of Sports Medicine recommendations. A mixed effects model was used for analysis. Twenty-six people finished the study, with average reported exercise participation of 93%. No negative effects of exercise were observed. Significant increase in hip flexor muscle strength was observed on the left, but not the right. No changes were observed in walking speed and endurance measures. This pilot study of home-based resistance training showed a modest improvement in hip strength but only on one side. The lack of a more significant improvement and no improvement in walking measures suggests that this training protocol may not be optimal for people with CMT and that patients may need to stratified differently for training studies in CMT.

    Objective: Mutations in mitofusin 2 (MFN2) are the most common cause of axonal Charcot-Marie-Tooth disease (CMT2). Over 50 mutations have been reported, mainly causing autosomal dominant disease, though families with homozygous or compound heterozygous mutations have been described. We present 3 families with early-onset CMT2 associated with compound heterozygous MFN2 mutations. Transcriptional analysis was performed to investigate the effects of the mutations. Methods: Patients were examined clinically and electrophysiologically; parents were also examined where available. Genetic investigations included MFN2 DNA sequencing and dosage analysis by multiplex ligation-dependent probe amplification. MFN2 mRNA transcripts from blood lymphocytes were analyzed in 2 families. Results: Compound heterozygosity for MFN2 mutations was associated with early-onset CMT2 of varying severity between pedigrees. Parents, where examined, were unaffected and were heterozygous for the expected mutations. Four novel mutations were detected (one missense, one nonsense, an intragenic deletion of exons 7 + 8, and a 3–base pair deletion), as well as 2 previously reported missense mutations. Transcriptional analysis demonstrated aberrant splicing of the exonic deletion and indicated nonsense-mediated decay of mutant alleles with premature truncating mutations. Conclusions: Our findings confirm that MFN2 mutations can cause early-onset CMT2 with apparent recessive inheritance. Novel genetic findings include an intragenic MFN2 deletion and nonsense-mediated decay. Carrier parents were asymptomatic, suggesting that MFN2 null alleles can be nonpathogenic unless coinherited with another mutation. PMID:21715711

    X-linked Charcot-Marie-Tooth disease (CMT1X) is the second most common inherited neuropathy, caused by mutations in gap junction beta-1 (GJB1). Males have a uniformly moderately severe phenotype while females have a variable phenotype, suggested to be due to X inactivation. We aimed to assess X inactivation pattern in females with CMT1X and correlate this with phenotype using the CMT examination score to determine whether the X inactivation pattern accounted for the variable phenotype in females with CMT1X. We determined X inactivation pattern in 67 females with CMT1X and 24 controls using the androgen receptor assay. We were able to determine which X chromosome carried the GJB1 mutation in 30 females. There was no difference in X inactivation pattern between patients and controls. In addition, there was no correlation between X inactivation pattern in blood and phenotype. A possible explanation for these findings is that the X inactivation pattern in Schwann cells rather than in blood may explain the variable phenotype in females with CMT1X.

    The X-linked dominant form of Charcot-Marie-Tooth syndrome (CMTX) is a clinically and genetically heterogeneous hereditary disorder of the peripheral nerves caused by mutations in the GJB1 gene that encodes a gap junction protein named connexin 32 (Cx32). Clinically, CMTX is characterized by peripheral motor and sensory deficit with muscle atrophy. A couple with a previous history of pregnancy termination after being diagnosed positive for CMTX by chorionic villus sampling, was referred for preimplantation genetic diagnosis (PGD). The female partner carried the causative H94Q, characterized by a C-->G substitution in codon 94 of exon 2 of the GJB1 gene. Embryos obtained after intracytoplasmic sperm injection (ICSI) were evaluated for the presence of the mother's mutation using polymerase chain reaction (PCR), followed by mutation analysis performed using the minisequencing method. Amelogenin sequences on the X and Y chromosomes were also co-amplified to provide a correlation between embryo gender and mutation presence. A single PGD cycle was performed, involving nine fertilized oocytes, five of which developed into good quality embryos useful for biopsy. Two unaffected embryos were transferred, resulting in a singleton pregnancy followed by the birth of a healthy female.

    Average velocities for time intervals ranging from <1 to 15 years were measured by tracking ice-surface patterns on sequential Landsat and European Remote-sensing Satellite synthetic aperture radar images. Velocities of Thwaites Glacier range from 2.2 km a-1 above the grounding line to 3.4 km a-1 at the limit of measurements on Thwaites Glacier ice tongue. The glacier increases in velocity by about 1 km a-1 where it crosses the grounding line. Over the period 1984-93, Thwaites Glacier ice tongue accelerated by about 0.6 km a-1. Velocities of the floating part of several minor glaciers and some ice shelves are also determined: Land Glacier, 1.7-1.9 km a-1; DeVicq Glacier, 0.7-1.1 km a-1; Dotson Ice Shelf, 0.2-0.5 km a-1; Getz Ice Shelf, 0.2-0.8 km a-1; and Sulzberger Ice Shelf, 0.01-0.02 km a-1. The high velocities along the Marie Byrd Land coast are consistent with the high precipitation rates over West Antarctica and, for some of the glaciers, the lack of buttressing ice shelves.

    Charcot-Marie-Tooth disease (CMT) is a heterogeneous group of peripheral neuropathies with diverse genetic causes. In this study, we identified p.I43N mutation in PMP2 from a family exhibiting autosomal dominant demyelinating CMT neuropathy by whole exome sequencing and characterized the clinical features. The age at onset was the first to second decades and muscle atrophy started in the distal portion of the leg. Predominant fatty replacement in the anterior and lateral compartment was similar to that in CMT1A caused by PMP22 duplication. Sural nerve biopsy showed onion bulbs and degenerating fibers with various myelin abnormalities. The relevance of PMP2 mutation as a genetic cause of dominant CMT1 was assessed using transgenic mouse models. Transgenic mice expressing wild type or mutant (p.I43N) PMP2 exhibited abnormal motor function. Electrophysiological data revealed that both mice had reduced motor nerve conduction velocities (MNCV). Electron microscopy revealed that demyelinating fibers and internodal lengths were shortened in both transgenic mice. These data imply that overexpression of wild type as well as mutant PMP2 also causes the CMT1 phenotype, which has been documented in the PMP22. This report might expand the genetic and clinical features of CMT and a further mechanism study will enhance our understanding of PMP2-associated peripheral neuropathy. PMID:26828946

    Summary Mutations in peripheral myelin protein 22 (PMP22) can result in the common peripheral neuropathy, Charcot-Marie-Tooth disease (CMTD). The Leu16Pro mutation in PMP22 results in misassembly of the protein, which causes the Trembler-J (TrJ) disease phenotype. Here we elucidate the structural defects present in a partially folded state of TrJ PMP22 that are decisive in promoting CMTD-causing misfolding. In this state transmembrane helices 2-4 (TM2-4) form a molten-globular bundle while transmembrane helix 1 (TM1) is dissociated from this bundle. The TrJ mutation was seen to profoundly disrupt the TM1 helix, resulting in increased backbone dynamics and changes in the tertiary interactions of TM1 with the PMP22 TM2-4 core in the folded state. Consequently, TM1 undergoes enhanced dissociation from the other transmembrane segments in TrJ PMP22, becoming available for recognition and sequestration by protein folding quality control, leading to loss of function and toxic accumulation of aggregates that results in CMTD.

    We identified the main features of Charcot-Marie-Tooth (CMT) disease, type 4F, caused by a periaxin gene (PRX) mutation in Japanese patients. Periaxin is known as one of the key myelination molecules, forming tight junction between myelin loop and axon. We collected 427 DNA samples from individuals with CMT or CMT-related neuropathy, negative for PMP22 duplication. We investigated PRX mutations using a purpose-built resequencing array screen during the period 2006-2012. We detected two types of PRX mutations in three patients; one patient showed a novel homozygous p.D651N mutation and the other two showed homozygous p.R1070X mutation. All PRX mutations reported so far have been of nonsense or frameshift type. In this study, we found homozygous missense mutation p.D651N. Aspartate 651 is located in a repeat domain; its position might indicate an important function. PRX mutations usually lead to early-onset, autosomal-recessive demyelinating CMT neuropathy 4F (CMT4F) or Dejerine-Sottas disease; their clinical phenotypes are severe. In our three patients, the onset of the disease was at the age of 27 years or later, and their clinical phenotypes were milder compared with those reported in previous studies. We showed a variation of clinical phenotypes for CMT4F caused by a novel, nonsense PRX mutation. PMID:22847150

    Purpose: Charcot-Marie-Tooth disease (CMT) is the most common type of inherited peripheral neuropathy and has a high degree of genetic heterogeneity. CMT with concurrent diabetes mellitus (DM) is rare. The purpose of this study is to explore the genetic, clinical and pathological characteristics of the patients with CMT and concurrent DM. Methods: We investigated gene mutations (the peripheral myelin protein 22 gene, myelin protein zero gene, lipopolysaccharide-induced tumor necrosis factor-α factor gene, early growth response gene and the neurofilament light chain gene loci) of a relatively large and typical Chinese family with CMT1 and concurrent DM2. From the literature, we also retrieved all reported families and single cases with CMT and concurrent DM. We comprehensively analyzed the characteristics of total 33 patients with CMT and concurrent DM, and further compared these characteristics with those of patients of diabetic peripheral neuropathy (DPN). Results: Patients with CMT and concurrent DM had some relatively independent characteristics and pathogenic mechanisms. So we designated that kind of characteristic demyelinating CMT which accompanies DM as Yu-Xie syndrome (YXS), a new specific clinical subtype of CMT. Conclusion: CMT is an etiologic factor of DM, even though the intrinsic association between CMT and DM still remains further exploration. PMID:25120817

    Missense mutants in the late endosomal Rab7 GTPase cause the autosomal dominant peripheral neuropathy Charcot-Marie-Tooth disease type 2B (CMT2B). As yet, the pathological mechanisms connecting mutant Rab7 protein expression to altered neuronal function are undefined. Here, we analyze the effects Rab7 CMT2B mutants on nerve growth factor (NGF) dependent intracellular signaling in PC12 cells. The nerve growth factor receptor TrkA interacted similarly with Rab7 wild-type and CMT2B mutant proteins, but the mutant proteins significantly enhanced TrkA phosphorylation in response to brief NGF stimulation. Two downstream signaling pathways (Erk1/2 and Akt) that are directly activated in response to phospho-TrkA were differentially affected. Akt signaling, arising in response to activated TrkA at the plasma membrane was unaffected. However Erk1/2 phosphorylation, triggered on signaling endosomes, was increased. Cytoplasmic phospho-Erk1/2 persisted at elevated levels relative to control samples for up to 24 h following NGF stimulation. Nuclear shuttling of phospho Erk1/2, which is required to induce MAPK phosphatase expression and down regulate signaling, was greatly reduced by the Rab7 CMT2B mutants and explains the previously reported inhibition in PC12 neurite outgrowth. In conclusion, the data demonstrate a mechanistic link between Rab7 CMT2B mutants and altered TrkA and Erk1/2 signaling from endosomes. PMID:21151572

    2004-02-01

    During the last decade, molecular biology has demonstrated the extraordinary heterogeneity of genetic abnormalities in Charcot-Marie-Tooth disease (CMT). The main phenotypes are either of the demyelinating or axonal type, transmitted with dominant or recessive autosomal inheritance. X-linked CMT is less rare than it was initially described and is often misdiagnosed as autosomal dominant type. Linked phenotypes are Dejerine-Sottas disease, congenital hypomyelinization and hereditary neuropathy with susceptibility to pressure palsies. Each phenotype can be due to different genotypes and concerned genes are numerous. Conversely, each genotype can express different phenotypes. Molecular diagnostic strategy of CMT is mainly baised on three elements: - phenotypic expertise which is based on the analysis of the inheritance mode and on electrophysiological data, which are peculiar in CMTX - knowledge of respective occurrence of the different genotypes and phenotypes which is increasing - technical feasibility of molecular biology methods which is important to consider, even though progress are fastly coming. According to these considerations, a strategy is proposed for molecular diagnosis of CMT. PMID:15034475

    Mutations in mitofusin 2 (MFN2) have been reported in Charcot-Marie-Tooth type 2 (CMT2) families. To study the distribution of mutations in MFN2 we screened 323 families and isolated patients with distinct CMT phenotypes. In 29 probands, we identified 22 distinct MFN2 mutations, and 14 of these mutations have not been reported before. All mutations were located in the cytoplasmic domains of the MFN2 protein. Patients presented with a classical but rather severe CMT phenotype, since 28% of them were wheelchair-dependent. Some had additional features as optic atrophy. Most patients had an early onset and severe disease status, whereas a smaller group experienced a later onset and milder disease course. Electrophysiological data showed in the majority of patients normal to slightly reduced nerve conduction velocities with often severely reduced amplitudes of the compound motor and sensory nerve action potentials. Examination of sural nerve specimens showed loss of large myelinated fibres and degenerative mitochondrial changes. In patients with a documented family history of CMT2 the frequency of MFN2 mutations was 33% indicating that MFN2 mutations are a major cause in this population.

    This brief review of current research progress on Charcot-Marie-Tooth (CMT) disease is a summary of discussions initiated at the Hereditary Neuropathy Foundation (HNF) scientific advisory board meeting on November 7, 2014. It covers recent published and unpublished in vitro and in vivo research. We discuss recent promising preclinical work for CMT1A, the development of new biomarkers, the characterization of different animal models, and the analysis of the frequency of gene mutations in patients with CMT. We also describe how progress in related fields may benefit CMT therapeutic development, including the potential of gene therapy and stem cell research. We also discuss the potential to assess and improve the quality of life of CMT patients. This summary of CMT research identifies some of the gaps which may have an impact on upcoming clinical trials. We provide some priorities for CMT research and areas which HNF can support. The goal of this review is to inform the scientific community about ongoing research and to avoid unnecessary overlap, while also highlighting areas ripe for further investigation. The general collaborative approach we have taken may be useful for other rare neurological diseases.

    Charcot-Marie-Tooth (CMT) disease is an inherited neurological disorder. Mutations in the small integral membrane protein of the lysosome/late endosome (SIMPLE) account for the rare autosomal-dominant demyelination in CMT1C patients. Understanding the molecular basis of CMT1C pathogenesis is impeded, in part, by perplexity about the role of SIMPLE, which is expressed in multiple cell types. Here we show that SIMPLE resides within the intraluminal vesicles of multivesicular bodies (MVBs) and inside exosomes, which are nanovesicles secreted extracellularly. Targeting of SIMPLE to exosomes is modulated by positive and negative regulatory motifs. We also find that expression of SIMPLE increases the number of exosomes and secretion of exosome proteins. We engineer a point mutation on the SIMPLE allele and generate a physiological mouse model that expresses CMT1C-mutated SIMPLE at the endogenous level. We find that CMT1C mouse primary embryonic fibroblasts show decreased number of exosomes and reduced secretion of exosome proteins, in part due to improper formation of MVBs. CMT1C patient B cells and CMT1C mouse primary Schwann cells show similar defects. Together the data indicate that SIMPLE regulates the production of exosomes by modulating the formation of MVBs. Dysregulated endosomal trafficking and changes in the landscape of exosome-mediated intercellular communications may place an overwhelming burden on the nervous system and account for CMT1C molecular pathogenesis.

    The School of Geography at Queen Mary, University of London has been running a Level 6 (undergraduate) module in "Geodiversity & Geoconservation" since 2004. The course is based around the book Geodiversity: valuing and conserving abiotic nature (John Wiley, 2004) but lectures are used to update each topic based on the latest research. The course is divided into 5 parts: 1. Defining and describing geodiversity - which discusses the concept of geodiversity, its definition and the nature of the geodiversity of Planet Earth; 2. Values of, and threats to, geodiversity - a lecture on valuing geodiversity is now based around important research on the role of geodiversity in "ecosystem services" assessments. A second lecture covers the major threats to geodiversity; 3. The protected area approach - lectures here cover geological World Heritage Sites, Global Geoparks, GSSPs, and national geoconservation systems in the UK, USA and other parts of the world; 4. Protecting geodiversity in the wider landscape - the contribution of geology and geomorphology to landscape character are described, together with the role of land-use planning and policy-making in protecting geodiversity. 5. Putting it all together - lectures here emphasize that geodiversity is an important basis for geoconservation, that different geoconservation methods are appropriate to different elements of geodiversity, and that integrated geo/bio conservation is essential. A field trip to three Chalk/Quaternary Sites of Special Scientific Interest in East Sussex is included which discusses some of the planning issues that have arisen at these sites, a theme that is expanded in the lectures.

    A 76-year-old female presented to our hospital with a 2 cm firm, nontender, protuberant umbilical nodule. She received treatment with antibiotics for suspected granuloma, with no improvement after two months. High levels of CA125 as well as an ovarian cyst and intrathoracic and intra-abdominal lesions on imaging studies made us suspect an ovarian cancer with a Sister Mary Joseph nodule (SMJN) and other metastases. A bilateral salpingo-oophorectomy and umbilical and omentum tumor resections were performed and a metastatic ovarian serous adenocarcinoma was diagnosed by histopathology. After surgery, the patient received chemotherapy with paclitaxel, carboplatin, and bevacizumab; however paclitaxel allergy was observed. As a result, chemotherapy continued with carboplatin and bevacizumab every three weeks for a total of 6 courses. Currently, she is still undergoing treatment with bevacizumab and CA125 levels have been progressively decreasing. SMJN is a rare umbilical metastasis which needs to be considered as a differential diagnosis in the presence of an umbilical tumor for prompt treatment initiation. PMID:27635270

    Background Marie Unna hereditary hypotrichosis (MUHH) is an autosomal dominant disorder characterised by coarse, wiry, twisted hair developed in early childhood and subsequent progressive hair loss. MUHH is a genetically heterogeneous disorder. No gene in 1p21.1–1q21.3 region responsible for MUHH has been identified. Methods Exome sequencing was performed on two affected subjects, who had normal vertex hair and modest alopecia, and one unaffected individual from a four-generation MUHH family of which our previous linkage study mapped the MUHH locus on chromosome 1p21.1–1q21.3. Results We identified a missense mutation in EPS8L3 (NM_024526.3: exon2: c.22G->A:p.Ala8Thr) within 1p21.1–1q21.3. Sanger sequencing confirmed the cosegregation of this mutation with the disease phenotype in the family by demonstrating the presence of the heterozygous mutation in all the eight affected and absence in all the seven unaffected individuals. This mutation was found to be absent in 676 unrelated healthy controls and 781 patients of other disease from another unpublished project of our group. Conclusions Taken together, our results suggest that EPS8L3 is a causative gene for MUHH, which was helpful for advancing us on understanding of the pathogenesis of MUHH. Our study also has further demonstrated the effectiveness of combining exome sequencing with linkage information for identifying Mendelian disease genes. PMID:23099647

    Charcot-Marie-Tooth (CMT) disease is among the most common inherited neurological disorders. Mutations in the gene mitofusin 2 (MFN2) cause the axonal subtype CMT2A, which has also been shown to be associated with optic atrophy, clinical signs of first motor neuron involvement, and early onset stroke. Mutations in MFN2 account for up to 20–30% of all axonal CMT type 2 cases. To further investigate the prevalence of MFN2 mutations and to add to the genotypic spectrum, we sequenced all exons of MFN2 in a cohort of 39 CMT2 patients. We identified seven variants, four of which are novel. One previously described change was co-inherited with a PMP22 duplication, which itself causes the demyelinating form CMT1A. Another mutation was a novel in frame deletion, which is a rare occurrence in the genotypic spectrum of MFN2 characterized mainly by missense mutations. Our results confirm a MFN2 mutation rate of ~ 15–20% in CMT2. PMID:21258814

  13. Animal models of Charcot-Marie-Tooth disease type 1A.

    The most frequent genetic subtype of Charcot-Marie-Tooth disease is CMT1A, linked to chromosome 17p11.2. In the majority of cases, CMT1A is a gene dosage disease associated with a 1.5 Mb large genomic duplication. Transgenic models with extra copies of the Pmp22 gene have provided formal proof that overexpression of only this candidate gene is sufficent to cause peripheral demyelination, onion bulb formation, secondary axonal loss, and progressive muscle atrophy, the pathological hallmarks of CMT1A. The transgenic CMT rat with about 1.6-fold PMP22 overexpression exhibits clinical abnormalities, such as reduced nerve conduction velocity and lower grip strength that mimick findings in CMT1A patients. Also transgenic mice, carrying yeast artifical chromosomes as Pmp22 transgenes, demonstrate the variability of disease expression as a function of increased gene dosage. Recently, the first rational experimental therapies of CMT1A were tested, using transgenic animal models. In one proof-of-principle study with the CMT rat, a synthetic antagonist of the nuclear progesterone receptor was shown to reduce PMP22 overexpression and to ameliorate the clinical severity. In another study, administration of ascorbic acid, an essential factor of in vitro myelination, prolonged the survival and restored myelination of a dysmyelinated mouse model. Application of gene expression analysis to nerve biopsies that are readily available from such CMT1A animal models might identify additional pharmacological targets.

    Charcot-Marie-Tooth disease (CMT), also known as hereditary motor and sensory neuropathy, is a heterogeneous group of slowly progressive, degenerative disorders of peripheral nerve. X-linked CMT (CMTX) (McKusick 302800), a subdivision of type I, or demyelinating, CMT is an X-linked dominant condition with variable penetrance. Previous linkage analysis using RFLPs demonstrated linkage to markers on the proximal long and short arms of the X chromosome, with the more likely localization on the proximal long arm of the X chromosome. Available variable simple-sequence repeats (VSSRs) broaden the possibilities for linkage analysis. This paper presents new linkage data and recombination analysis derived from work with four VSSR markers - AR, PGKP1, DXS453, and DXYS1X - in addition to analysis using RFLP markers described elsewhere. These studies localize the CMTX gene to the proximal Xq segment between PGKP1 (Xq11.2-12) and DXS72 (Xq21.1), with a combined maximum multipoint lod score of 15.3 at DXS453 ([theta] = 0). 32 refs., 3 figs., 2 tabs.

    PNKP (polynucleotide kinase 3'-phosphatase, OMIM #605610) product is involved in the repair of strand breaks and base damage in the DNA molecule mainly caused by radical oxygen species. Deleterious variants affecting this gene have been previously associated with microcephaly, epilepsy, and developmental delay.(1) According to a previous report, homozygous loss-of-function substitution in PNKP was associated with cerebellar atrophy, neuropathy, microcephaly, epilepsy, and intellectual disability.(2) Recently, whole-exome sequencing (WES) performed in a cohort of Portuguese families with ataxia with oculomotor apraxia (AOA) disclosed pathogenic variants in PNKP in 11 individuals. Other clinical features in that study included neuropathy, dystonia, cognitive impairment, decreased vibration sense, pyramidal signs, mild elevation in α-fetoprotein, and low levels of albumin. This condition was named AOA type 4 (OMIM #616267), as the phenotype of AOA has been previously associated with 3 other genes: APTX, SETX, and PIK3R5.(3) Altogether, these reports demonstrate the great phenotypic diversity associated with PNKP mutations. In this article, we further enlarge this variability by demonstrating that early-onset axonal sensory-motor neuropathy (or axonal Charcot-Marie-Tooth (CMT) disease) followed years later by ataxia without oculomotor apraxia can be caused by deleterious variants in PNKP. Full consent was obtained from the patient and his parents for this publication. This study was approved by institutional ethics committees. PMID:27066567

    Charcot-Marie-Tooth (CMT) disease is the most common inherited neuropathy and one of the most common inherited diseases in humans. The diagnosis of CMT is traditionally made by the neurologic specialist, yet the optimal management of CMT patients includes genetic counselors, physical and occupational therapists, physiatrists, orthotists, mental health providers, and community resources. Rapidly developing genetic discoveries and novel gene discovery techniques continue to add a growing number of genetic subtypes of CMT. The first large clinical natural history and therapeutic trials have added to our knowledge of each CMT subtype and revealed how CMT impacts patient quality of life. In this review, we discuss several important trends in CMT research factors that will require a collaborative multidisciplinary approach. These include the development of large multicenter patient registries, standardized clinical instruments to assess disease progression and disability, and increasing recognition and use of patient-reported outcome measures. These developments will continue to guide strategies in long-term multidisciplinary efforts to maintain quality of life and preserve functionality in CMT patients.

  17. Selective glacial erosion and weathering zones in the coastal mountains of Marie Byrd Land, Antarctica

    In the coastal mountains of Marie Byrd Land, Antarctica, there is a juxtaposition of ice moulded landforms at lower altitudes and upstanding summits with weathered surfaces bearing tors. This paper uses geomorphological mapping and exposure dating to test two hypotheses commonly used to explain such a landscape contrast: either the pattern reflects contrasts in glacial erosion related to the basal thermal regime beneath a former ice sheet or it represents a periglacial trimline marking the upper limit of ice cover during the Last Glacial Maximum (LGM). Cosmogenic nuclide measurements on erratics show that the mountains were covered by ice on several occasions, most recently during the LGM. Similar measurements on bedrock show that fragile landforms on weathered surfaces survived many glaciations. Nuclide concentrations in bedrock indicate both that subglacial erosion is insignificant and that ice-free periods of periglacial weathering are longer at higher elevations. We conclude that the pattern of landscape modification reflects both topographically controlled contrasts in the basal thermal regime of overriding ice and the longer exposure to periglacial conditions at higher elevations. In addition, the combination of nuclide data and the wider pattern of striations shows that the LGM ice cover was thinner than predicted by ice sheet models assuming equilibrium conditions, that ice sheet thinning has occurred from 10,400 years ago to the present, and that regional flow by overriding ice has been replaced by radial ice flow from local glaciers centred on individual mountain massifs.

    The Island of Sainte Marie is located at 6 km from the Eastern Coast of Madagascar. The climate is a muggy tropical one, with an average temperature rising above 20 degrees C all along the year and precipitations superior to 2500 mm. In 1990, a clinical surveillance of ten affections has been performed by every health units of the Island: paludal syndromes, nutrition disorders and anemia have been the focus of symptomatic definition. Blood samples have been taken from 100 pupils of the village of Ambodiforaha for hemogram determination and research of malaria hematozoon. Four pupils out of five show biological anemia, more than 10% suffer from acute anemia (less than 3.5 millions of red blood cells for each microliters, hematocrit inferior to 30, less than 9 g of hemoglobin for 100 ml). 87% suffer from nutritional anemia, 17% from iron-deficient anemia. Those figures cannot be found in health statistics. There is a high rate of nutritional and iron deficient anemia, but the problem is not well perceived or not at all by the health system. Anemia must be related to the strength of paludal transmission, to the importance of nutrition disorders and the prevalence of intestinal parasitosis. A better knowledge of the epidemiology of anemias and their morbid consequences would allow the setting of a prevention programme useful for children under 5 years and for pregnant women.

    The X-linked form of Charcot-Marie-Tooth disease (CMT1X) is the second most common form of hereditary motor and sensory neuropathy. The clinical phenotype is characterized by progressive weakness, atrophy, and sensory abnormalities that are most pronounced in the distal extremities. Some patients have CNS manifestations. Affected males have moderate to severe symptoms, whereas heterozygous females are usually less affected. Neurophysiology shows intermediate slowing of conduction and length-dependent axonal loss. Nerve biopsies show more prominent axonal degeneration than de/remyelination. Mutations in GJB1, the gene that encodes the gap junction (GJ) protein connexin32 (Cx32) cause CMT1X; more than 400 different mutations have been described. Many Cx32 mutants fail to form functional GJs, or form GJs with abnormal biophysical properties. Schwann cells and oligodendrocytes express Cx32, and the GJs formed by Cx32 play an important role in the homeostasis of myelinated axons. Animal models of CMT1X demonstrate that loss of Cx32 in myelinating Schwann cells causes a demyelinating neuropathy. Effective therapies remain to be developed. PMID:22771394

    Charcot-Marie-Tooth (CMT) disease is genetically heterogeneous and subdivided into demyelinating (CMT 1) and axonal (CMT 2) types based on neurophysiology findings. CMT1A, the commonest form associated with duplication of the PMP22 segment on chromosome 17p, often arises in childhood but is generally a slowly progressive disease. We report 2 children presenting with clinical features of an acute inflammatory demyelinating polyneuropathy (AIDP) who were subsequently diagnosed with underlying CMT1A. Both children had neurophysiology and histopathology features consistent with CMT1. Immunoglobulin treatment was initiated considering the evidence of superimposed inflammation and appeared to modify disease progression. Our findings indicate that CMT1A predisposes to a superimposed inflammatory neuropathy. Recognition of this association is difficult, particularly in children without clear family history, but of great importance as immunomodulatory treatment may improve outcome. In addition, we postulate that an underlying genetic polyneuropathy should be suspected if the recovery from AIDP is slower than expected, or incomplete. PMID:19809938

    The Marie Curie Cancer Care (2003) Spiritual and Religious Care Competencies for Specialist Palliative Care provide a common language for healthcare practitioners in the nebulous area of spiritual care. The development of a pilot blended learning event, as described in this paper, sought to integrate the competencies into practice by providing opportunities both online and in the classroom to explore this aspect of holistic care in depth. In the planning stages, multiprofessional focus groups determined the level of delivery, and emerging themes shaped the content. Self-awareness and reflection were key features and part of the overall process to improve competency. The features of the virtual learning environment (VLE) used were video, facilitated asynchronous discussion and direct links to key articles and documents, while interactive classroom activities built on prior learning. Evaluation covered all aspects of the course design from participant and facilitator perspectives. Participant comments were overwhelmingly positive in relation to the content and chosen delivery methods with concerns about online learning proving unfounded.

    As part of its investigation of 'Victoria Crater,' NASA's Mars Exploration Rover Opportunity examined a promontory called 'Cape Verde' from the vantage point of 'Cape St. Mary,' the next promontory clockwise around the crater's deeply scalloped rim. This view of Cape Verde combines several exposures taken by the rover's panoramic camera into an approximately false-color mosaic. The exposures were taken during mid-afternoon lighting conditions.

    The upper portion of the crater wall contains a jumble of material tossed outward by the impact that excavated the crater. This vertical cross-section through the blanket of ejected material surrounding the crater was exposed by erosion that expanded the crater outward from its original diameter, according to scientists' interpretation of the observations. Below the jumbled material in the upper part of the wall are layers that survive relatively intact from before the crater-causing impact.

    The images combined into this mosaic were taken during the 1,006th Martian day, or sol, of Opportunity's Mars-surface mission (Nov. 22, 2006). The panoramic camera took them through the camera's 750-nanometer, 530-nanometer and 430-nanometer filters. The false color enhances subtle color differences among materials in the rocks and soils of the scene.

This vertical cross-section through the blanket of ejected material surrounding the crater was exposed by erosion that expanded the crater outward from its original diameter, according to scientists' interpretation of the observations. Below the jumbled material in the upper part of the wall are layers that survive relatively intact from before the crater-causing impact.

    The images combined into this mosaic were taken during the 1,006th Martian day, or sol, of Opportunity's Mars-surface mission (Nov. 22, 2006). The panoramic camera took them through the camera's 750-nanometer, 530-nanometer and 430-nanometer filters.

  8. An encounter between psychology and religion: humanistic psychology and the Immaculate Heart of Mary nuns.

    In the 1960s, humanistic psychology changed the relationship between psychology and religion by actively asserting the value of individual experience and self-expression. This was particularly evident in the encounter group movement. Beginning in 1967, Carl Rogers conducted a series of encounter groups, in order to promote "self-directed change in an educational system," for the Sisters of the Immaculate Heart of Mary, a religious order in California running an educational system. William Coulson, one of Rogers's associates in the project, later charged that the encounter groups undermined the religious order and played a major contributing part in the breakup of the order in 1970. The article examines these charges, situating the incident within the context of the changes occurring in religious life and in psychology in the 1960s. The article concludes that an already existing conflict the nuns had with the conservative Cardinal McIntyre of Los Angeles led to the departure of some 300 nuns from the order, who began the Immaculate Heart Community, an organization existing today. Nevertheless, encounter groups proved to be a psychological technology that helped to infuse a modern psychological--specifically, a humanistic psychological--perspective into contemporary religious life.

    Marie-Galante basin in the Lesser Antilles fore arc has experienced high amplitude (up to several thousand meters) vertical movements in response to both local tectonic in the fore-arc (trench perpendicular extensional tectonic) and geodynamical events at the plate interface, such as, long term interplate coupling changes, or ridges subduction or alternating period of under-platting/basal erosion... During the KaShallow cruises, we acquired ca. 3500km of high-resolution multichannel seismic reflection data (sparker and miniGI airgun sources), together with HR multibeam bathymetric (50m gridspacing DTM with ±2m depth precision) in the basin and over the shallow-water carbonate platforms surrounding the fore-arc islands. This geophysical dataset completes already existing seismic reflection data of lower resolution but deeper penetration. A systematic rock sampling using piston and rock corers and 2 ROV dives along remarkable cliffs, together with old dredge samples, provided petrological and sedimentary facies description, and datation (radiochronology and Micro/Nanno fossils) of the main stratigraphic series identified in seismic reflection through the basin. The basin divides into 3 sedimentary environments. We identify the architecture of the offshore carbonate platforms around the fore arc island and between them. Seismic profiles reveal the platforms prograding systems at their boundaries. This allows attempting a correlation between all the onshore/offshore archipelago platforms. Particularly, we evidence that the early Pleistocene upper series outcropping onshore extends offshore, and late Pleistocene/Holocene erosional surfaces are revealed. The "deep bassin", gently deepens southeastward from the volcanic arc islands of Basse-Terre and Dominica to the deep (5000m bsl) forearc basin at the accretionnary prism. Seismic profiles reveal the turbiditic infill of the basin. ROV dives permit to sample early Miocene pelagic sediments, and cores sample the late

    The Sainte-Marie-aux-Mines (SMM) mines host one of the most famous and oldest silver deposits in Europe. The SMM district is located in the central part of the Vosges mountains, France, within gneiss and granites of the Moldanubian zone. The SMM district includes the Neuenberg E-W vein-type Cu-Ag-As/Pb-Zn deposit and the Altenberg N-S vein-type Pb-Zn-Ag deposit. Deposition of the SMM hydrothermal mineralization occurred under a brittle tectonic regime that might be connected to neo-Variscan and/or post-Variscan tectonics, in a similar way as the polymetallic vein deposits of the Black Forest, Germany. A structural study was done in the Neuenberg area, in the vicinity of the Saint-Jacques vein, and within the Gabe Gottes mine, considering the orientation, extent, chronology and density of faults as well as the nature of the infilling minerals. In the Gabe-Gottes mine, the Saint-Jacques vein comprises multiple successive, sub-parallel subvertical veinlets with gangue minerals, mostly carbonates and quartz, and metal-bearing phases, sulfides and sulfosalts. The veinlets are 2 to 50 cm thick and strike N80° to N110°, the earlier veins slightly dipping towards the north, and the latest one, to the south. Seven systems of faults were identified, which may be classified into three major groups formed respectively before, during and after the main stage of ore deposition: a) Pre-mineralization faults - These consist of sinistral NE-SW strike-slip faults, and NW-SE and NE-SW steeply dipping normal faults. These could be related to Carboniferous events considering their relationships with the granitoid intrusives present in the mine area (Brézouard leucogranite ~329 Ma), and the extensional tectonics developed during exhumation processes. b) Faults associated with the main ore-deposition - These faults could be related to late-Hercynian processes from compressional to extensional tectonic regimes. Mineralization controlling faults consist of dextral and sinistral E

    Large home ranges and extreme flexibility in ranging behaviors characterize most subarid dwelling haplorhines. However, the most comparable extant strepsirhine, Lemur catta, is characterized as having small home ranges with consistent boundaries. Since ranging studies on this species have been limited to gallery forest habitat, the author's goal is to identify ecological factors that affect range use of L. catta in one of the most resource-limited environments of its distribution. To conduct this study, ranging and behavioral data were collected on two nonoverlapping groups through all-day follows in the semidesert scrub environment of Cap Sainte-Marie (CSM), Madagascar. Data were collected from August 2007 through July 2008. Home range areas and day range lengths were generated using ArcGIS(®) 9.3. Other variables measured were habitat composition, diet richness, daily activity, and microclimate. Home range areas of CSM L. catta were very large relative to those of gallery forest L. catta, and there was great monthly variation. In contrast, day range lengths at CSM were either smaller than or approximated the size of comparative gallery forest groups. Temperature, sunning, and diet richness were associated with day range length for one but not for both groups and appear to be related to energy management needs. Based on these findings, the author suggests that L. catta is capable of extensive behavioral and ranging flexibility in the extremes of its environment. However, physiological constraints impose limitations that can interfere with its ability to adapt to even seemingly minor variations in microclimate and habitat structure within the same site.

    One experimental approach to hydraulic stimulation is to use fluid to propagate fractures but not to incorporate solid proppant material in the design. The elimination of solid material negates problems related to wellbore sand proppant influx and allows better fracture height control since extremely low injection rates can be used. The Mary Lee Coalbed was stimulated using a 53,000 gallon no-proppant treatment at a 1,150 foot deep test well located approximately 1,600 feet in advance of mining. The well produced for 147 days and gas flow rates declined sharply, ceasing when intercepted by mining. Production comparison of the no-proppant test with another test incorporating sand proppant indicates that the 53,000 gallon no-proppant treatment was less effective than the more conventional 21,000 gallon treatment. The results from the no-proppant test indicate that very few roof rock fluid penetrations occurred during the course of hydraulic stimulation. It cannot be determined, however, if sparsity of roof penetration was due to the use of very low injection rates or because roof rock in the physical test area was less jointed and, therefore, less prone to stimulation fluid invasions. Because gas flow results gathered are inconclusive, the application of no-proppant stimulation designs for other than research is not recommended at this time. The lower injection rate approach to fracture height control is, however, theoretically sound and because limiting upward fracture growth in coalbeds may be desirable to future borehole gas drainage activities, no-proppant experiments could be justified on a limited scale.

    BACKGROUND: In certain diseases, functional constraints establish a greater relationship with muscle power than muscle strength. However, in hereditary peripheral polyneuropathies, no such relationship was found in the literature. OBJECTIVE: In children with Charcot-Marie-Tooth (CMT), to identify the impact of muscle strength and range of movement on the static/dynamic balance and standing long jump based on quantitative and functional variables. METHOD: The study analyzed 19 participants aged between 6 and 16 years, of both genders and with clinical diagnoses of CMT of different subtypes. Anthropometric data, muscle strength of the lower limbs (hand-held dynamometer), ankle and knee range of movement, balance (Pediatric Balance Scale) and standing long jump distance were obtained by standardized procedures. For the statistical analysis, Pearson and Spearman correlation coefficients were used. RESULTS: There was a strong positive correlation between balance and the muscle strength of the right plantar flexors (r=0.61) and dorsiflexors (r=0.59) and a moderate correlation between balance and the muscle strength of inversion (r=0.41) and eversion of the right foot (r=0.44). For the long jump and range of movement, there was a weak positive correlation with right and left plantar flexion (r=0.20 and r=0.12, respectively) and left popliteal angle (r=0.25), and a poor negative correlation with left dorsiflexion (r=-0.15). CONCLUSIONS: The data on the patients analyzed suggests that the maintenance of distal muscle strength favors performance during balance tasks, while limitations in the range of movement of the legs seem not to be enough to influence the performance of the horizontal long jump.

    The interaction between myelinating Schwann cells and the axons they ensheath is mediated by cell adhesion molecules of the Cadm/Necl/SynCAM family. This family consists of four members: Cadm4/Necl4 and Cadm1/Necl2 are found in both glia and axons, whereas Cadm2/Necl3 and Cadm3/Necl1 are expressed by sensory and motor neurons. By generating mice lacking each of the Cadm genes, we now demonstrate that Cadm4 plays a role in the establishment of the myelin unit in the peripheral nervous system. Mice lacking Cadm4 (PGK-Cre/Cadm4fl/fl), but not Cadm1, Cadm2, or Cadm3, develop focal hypermyelination characterized by tomacula and myelin outfoldings, which are the hallmark of several Charcot-Marie-Tooth neuropathies. The absence of Cadm4 also resulted in abnormal axon–glial contact and redistribution of ion channels along the axon. These neuropathological features were also found in transgenic mice expressing a dominant-negative mutant of Cadm4 lacking its cytoplasmic domain in myelinating glia Tg(mbp-Cadm4dCT), as well as in mice lacking Cadm4 specifically in Schwann cells (DHH-Cre/Cadm4fl/fl). Consistent with these abnormalities, both PGK-Cre/Cadm4fl/fl and Tg(mbp-Cadm4dCT) mice exhibit impaired motor function and slower nerve conduction velocity. These findings indicate that Cadm4 regulates the growth of the myelin unit and the organization of the underlying axonal membrane. PMID:23825401

    Mutations in the GDAP1 gene cause different forms of Charcot-Marie-Tooth (CMT) disease, and the primary clinical expression of this disease is markedly variable in the dominant inheritance form (CMT type 2K; CMT2K), in which carriers of the GDAP1 p.R120W mutation can display a wide range of clinical severity. We investigated the JPH1 gene as a genetic modifier of clinical expression variability because junctophilin-1 (JPH1) is a good positional and functional candidate. We demonstrated that the JPH1-GDAP1 cluster forms a paralogon and is conserved in vertebrates. Moreover, both proteins play a role in Ca(2+) homeostasis, and we demonstrated that JPH1 is able to restore the store-operated Ca(2+) entry (SOCE) activity in GDAP1-silenced cells. After the mutational screening of JPH1 in a series of 24 CMT2K subjects who harbour the GDAP1 p.R120W mutation, we characterized the JPH1 p.R213P mutation in one patient with a more severe clinical picture. JPH1(p.R213P) cannot rescue the SOCE response in GDAP1-silenced cells. We observed that JPH1 colocalizes with STIM1, which is the activator of SOCE, in endoplasmic reticulum-plasma membrane puncta structures during Ca(2+) release in a GDAP1-dependent manner. However, when GDAP1(p.R120W) is expressed, JPH1 seems to be retained in mitochondria. We also established that the combination of GDAP1(p.R120W) and JPH1(p.R213P) dramatically reduces SOCE activity, mimicking the effect observed in GDAP1 knock-down cells. In summary, we conclude that JPH1 and GDAP1 share a common pathway and depend on each other; therefore, JPH1 can contribute to the phenotypical consequences of GDAP1 mutations.

    To describe a new test to quantitatively evaluate hand function in patients affected by Charcot-Marie-Tooth neuropathy (CMT). The sensor-engineered glove test (SEGT) was applied to CMT patients (N: 26) and compared with a cohort of healthy controls (HC, N: 26). CMT patients were further divided into subjects with clinically normal (group 1) or impaired hand (group 2) function. The SEGT parameters evaluated were touch duration, inter-tapping interval, and movement rate parameters of two different sequences: finger tapping (FT) and index-medium-ring-little (IMRL) performed at self-paced mode (SPM) and maximum velocity (MV). Hand function and strength were assessed by the 9-hole peg test (9HPT) and dynamometry. Disability of patients was measured by the CMT neuropathy score. CMT patients had significantly worst performances at SEGT than controls regarding the rate of execution of both FT (at MV) and IMRL sequences (at SPM and MV). The rate parameter at MV in IMRL sequence showed a significant trend of decreasing in its average between HC (n: 26, rate = 3.08 ± 0.52 Hz), group 1 (n: 9, rate = 2.64 ± 0.66 Hz) and group 2 (n: 17, rate = 2.19 ± 0.45 Hz) (p for trend <0.001). No correlations were found with either 9HPT, dynamometry, electrophysiology, and the CMT neuropathy score. The SEGT test is sensitive to show hand dysfunction in CMT patients, with and without clinically impaired hands.

    Charcot-Marie-Tooth (CMT) disease is the 'common' name for a range of hereditary peripheral neuropathies. CMT1 is the most common form and is transmitted in an autosomal dominant manner. CMT1A maps to chromosome 17p11.2 and is caused, in the majority of cases, by a 1.5 Mb DNA duplication, that includes the peripheral myelin protein 22 (PMP) gene. This paper reports on preimplantation genetic diagnosis (PGD) for CMT1A in five couples. The CMT1A duplication was detected by fluorescent PCR analysis using polymorphic (CA)n markers localized within the duplication. Single-cell PCR on blastomeres allowed genetic analysis of embryos obtained after ICSI. Only healthy unaffected embryos were transferred to the uterus. PCR experiments with single EBV-transformed lymphoblasts or with research blastomeres allowed the evaluation of amplification efficiencies, as well as contamination and allele drop-out (ADO) rates for each PCR protocol. Three simplex PCR protocols (using one primer pair) and two duplex PCR protocols (using two primer pairs) were developed for CMT1A. Additionally, a protocol using all three primer pairs in triplex was also established. Thirteen clinical ICSI-PGD cycles were performed for five couples (12 simplex PCR cycles and one duplex PCR cycle), resulting in seven embryo transfers. Three singleton pregnancies ensued in two couples and three healthy babies were delivered. This report describes different fluorescent PCR-based tests which allow efficient and accurate single-cell level detection of the CMT1A duplication. On the basis of the presence of the healthy allele of the affected parent-to-be (and/or absence of the affected one), healthy embryos can be selected for transfer. The assays are suitable for PGD for other couples who present with the same CMT1A duplication [depending on their informativity for the (CA)n markers available] as described here.

    Approximately 1 in 2500 Americans suffer from Charcot-Marie-Tooth (CMT) disease. The underlying disease mechanisms are unique in most forms of CMT, with many point mutations on various genes causing a toxic accumulation of misfolded proteins. Symptoms of the disease often present within the first two decades of life, with CMT1A patients having reduced compound muscle and sensory action potentials, slow nerve conduction velocities, sensory loss, progressive distal weakness, foot and hand deformities, decreased reflexes, bilateral foot drop and about 5% become wheelchair bound. In contrast, the ultra-rare disease Giant Axonal Neuropathy (GAN) is frequently described as a recessively inherited condition that results in progressive nerve death. GAN usually appears in early childhood and progresses slowly as neuronal injury becomes more severe and leads to death in the second or third decade. There are currently no treatments for any of the forms of CMTs or GAN. We suggest that further clinical studies should analyse electrical impedance myography as an outcome measure for CMT. Further, additional quality of life (QoL) assessments for these CMTs are required, and we need to identify GAN biomarkers as well as develop new genetic testing panels for both diseases. We propose that using the Global Registry of Inherited Neuropathy (GRIN) could be useful for many of these studies. Patient advocacy groups and professional organizations (such as the Hereditary Neuropathy Foundation (HNF), Hannah's Hope Fund (HHF), The Neuropathy Association (TNA) and the American Association of Neuromuscular and Electrodiagnostic Medicine (AANEM) can play a central role in educating clinicians and patients. Undertaking these studies will assist in the correct diagnosis of disease recruiting patients for clinical studies, and will ultimately improve the endpoints for clinical trials. By addressing obstacles that prevent industry investment in various forms of inherited neuropathies, we can

    Charcot-Marie-Tooth disease (CMT), the most common genetic neuropathy, affects about 1 in 2600 people in Norway and is found worldwide. CMT Type 1 (CMT1) has slow nerve conduction with demyelinated Schwann cells. Autosomal dominant CMT Type 1B (CMT1B) results from mutations in the myelin protein zero gene which directs the synthesis of more than half of all Schwann cell protein. This gene was mapped to the chromosome 1q22-1q23.1 borderline by fluorescence in situ hybridization. The first 7 of 7 reported CMT1B mutations are unique. Thus the most effective means to identify CMT1B mutations in at-risk family members and fetuses is to sequence the entire coding sequence in dominant or sporadic CMT patients without the CMT1A duplication. Of the 19 primers used in 16 pars to uniquely amplify the entire MPZ coding sequence, 6 primer pairs were used to amplify and sequence the 6 exons. The DyeDeoxy Terminator cycle sequencing method used with four different color fluorescent lables was superior to manual sequencing because it sequences more bases unambiguously from extracted genomic DNA samples within 24 hours. This protocol was used to test 28 CMT and Dejerine-Sottas patients without CMT1A gene duplication. Sequencing MPZ gene-specific amplified fragments identified 9 polymorphic sites within the 6 exons that encode the 248 amino acid MPZ protein. The large number of major CMT1B mutations identified by single strand sequencing are being verified by reverse strand sequencing and when possible, by restriction enzyme analysis. This protocol can be used to distringuish CMT1B patients from othre CMT phenotypes and to determine the CMT1B status of relatives both presymptomatically and prenatally.

    Charcot-Marie-Tooth disease (CMT) is a clinically and genetically heterogeneous group of disorders and is the most common inherited neuromuscular disorder, with an estimated overall prevalence of 17-40/10,000. Although there has been major advances in the understanding of the genetic basis of CMT in recent years, the most useful classification is still a neurophysiological classification that divides CMT into type 1 (demyelinating; median motor conduction velocity < 38 m/s) and type 2 (axonal; median motor conduction velocity > 38 m/s). An intermediate type is also increasingly being described. Inheritance can be autosomal-dominant (AD), X-linked, or autosomal-recessive (AR). AD CMT1 is the most common type of CMT and was the first form of CMT in which a causative gene was described. This review provides an up-to-date overview of AD CMT1 concentrating on the molecular genetics as the clinical, neurophysiological, and pathological features have been covered elsewhere. Four genes (PMP22, MPZ, LITAF, and EGR2) have been described in the last 15 yr associated with AD CMTI and a further gene (NEFL), originally described as causing AD CMT2 can also cause AD CMT1 (by neurophysiological criteria). Studies have shown many of these genes, when mutated, can cause a wide range of CMT phenotypes from the relatively mild CMT1 to the more severe Dejerine-Sottas disease and congenital hypomyelinating neuropathy, and even in some cases axonal CMT2. This review discusses what is known about these genes and in particular how they cause a peripheral neuropathy, when mutated. PMID:16775366
