  5. Are youth mentoring programs good value-for-money? An evaluation of the Big Brothers Big Sisters Melbourne Program

    PubMed Central

    Moodie, Marjory L; Fisher, Jane

    2009-01-01

    Background The Big Brothers Big Sisters (BBBS) program matches vulnerable young people with a trained, supervised adult volunteer as mentor. The young people are typically seriously disadvantaged, with multiple psychosocial problems. Methods Threshold analysis was undertaken to determine whether investment in the program was a worthwhile use of limited public funds. The potential cost savings were based on US estimates of life-time costs associated with high-risk youth who drop out-of-school and become adult criminals. The intervention was modelled for children aged 10–14 years residing in Melbourne in 2004. Results If the program serviced 2,208 of the most vulnerable young people, it would cost AUD 39.5 M. Assuming 50% were high-risk, the associated costs of their adult criminality would be AUD 3.3 billion. To break even, the program would need to avert high-risk behaviours in only 1.3% (14/1,104) of participants. Conclusion This indicative evaluation suggests that the BBBS program represents excellent 'value for money'. PMID:19178749

    The data indicate that the influence of a brother or sister is considerably greater upon the second born than upon the first born. The magnitude of the sex of sibling effect is probably dependent upon whether a sibling is present during the first few years of life, a period during which many enduring response patterns are being acquired. The…

  18. Catholic nursing sisters and brothers and racial justice in mid-20th-century America.

    PubMed

    Wall, Barbra Mann

    2009-01-01

    This historical article considers nursing's work for social justice in the 1960s civil rights movement through the lens of religious sisters and brothers who advocated for racial equality. The article examines Catholic nurses' work with African Americans in the mid-20th century that took place amid the prevailing social conditions of poverty and racial disempowerment, conditions that were linked to serious health consequences. Historical methodology is used within the framework of "bearing witness," a term often used in relation to the civil rights movement and one the sisters themselves employed. Two situations involving nurses in the mid-20th century are examined: the civil rights movement in Selma, Alabama, and the actions for racial justice in Chicago, Illinois. The thoughts and actions of Catholic sister and brother nurses in the mid-20th century are chronicled, including those few sister nurses who stepped outside their ordinary roles in an attempt to change an unjust system entirely.

  16. Retinitis pigmentosa, metaphyseal chondrodysplasia, and brachydactyly: an affected brother and sister.

    PubMed Central

    Phillips, C I; Wynne-Davies, R; Stokoe, N L; Newton, M

    1981-01-01

    A brother and sister, children of normal parents are described. They had retinitis pigmentosa, causing near-blindness as a result of very narrow fields of vision, associated with metaphyseal chondrodysplasia and marked shortening of the metacarpals and terminal phalanges. Autosomal recessive inheritance is suggested with a common biochemical cause for all these defects. This apparently new association of retinitis pigmentosa with a systemic bone dysplasia emphasises that this not uncommon clinical diagnosis has a variety of different possible causes.

Forty were classified as victims of brother-sister incest, 19 were classified as victims of father-daughter incest, and 232 were classified as victims of sexual abuse by an adult other than their father before reaching 18 years of age. The other 1,230 served as controls. The victims of brother-sister incest had significantly more problematic outcomes than controls on many measures (e.g., more likely than the controls to endorse feeling like damaged goods, thinking that they had suffered psychological injury, and having undergone psychological treatment for childhood sexual abuse). However, victims of brother-sister incest also had significantly less problematic outcomes than victims of father-daughter incest on some measures (e.g., significantly less likely than the father-daughter incest victims to endorse feeling like damaged goods, thinking that they had suffered psychological injury, and having undergone psychological treatment for childhood sexual abuse).

    PubMed

    McHale, S M; Sloan, J; Simeonsson, R J

    1986-12-01

    The subjects were 90 children between 6 and 15 years of age, 30 with autistic, 30 with mentally retarded, and 30 with nonhandicapped brothers or sisters. The children were questioned about their sibling relationships in an open-ended interview, and, in the case of children with handicapped siblings, they also responded to questions about particular problems they faced in regard to their brothers or sisters. In addition, mothers filled out a behavior rating scale in which they described the positive and negative aspects of their children's behavior toward the sibling. In general, children and mothers rated the sibling relationships positively. Group comparisons indicated that children with autistic and mentally retarded siblings did not differ on any self-report measures. Children with nonhandicapped siblings reported that their family relations were slightly more cohesive but otherwise did not differ in terms of their self-reports from children with handicapped siblings. Mothers of nonhandicapped children, however, rated the sibling relationships more negatively than did mothers of handicapped children. Further analyses revealed that status variables (age, gender, family size) were not as highly correlated with the quality of sibling relationships with handicapped children as were specific problem areas (e.g., perceptions of parental favoritism, coping ability, concerns about the handicapped child's future).

    2012-01-01

    The literature is full of examples of inbreeding avoidance, while recent mathematical models predict that inbreeding tolerance or even inbreeding preference should be expected under several realistic conditions like e.g. polygyny. We investigated male and female mate preferences with respect to relatedness in the fruit fly D. melanogaster. Experiments offered the choice between a first order relative (full-sibling or parent) and an unrelated individual with the same age and mating history. We found that females significantly preferred mating with their brothers, thus supporting inbreeding preference. Moreover, females did not avoid mating with their fathers, and males did not avoid mating with their sisters, thus supporting inbreeding tolerance. Our experiments therefore add empirical evidence for inbreeding preference, which strengthens the prediction that inbreeding tolerance and preference can evolve under specific circumstances through the positive effects on inclusive fitness.

  2. Big brothers and little sisters? Sex selection and birth order.

    PubMed

    Salmon, Catherine

    2007-09-01

    Should you be allowed to choose the sex of your child? Even before the advent of modern reproductive technologies, people have expressed interest in producing a child of a specific sex, trying everything from herbal treatments to sexual positions that have been claimed to produce a male or female child. Modern technologies such as flow cytometry make this a realistic possibility but what might the consequences be? In India and China, a preference for male offspring has led (via abortion) to a significant sex-ratio imbalance in those populations. Do other countries express strong preferences for male or female offspring? This article will address the possible birth order implications. Will we live in a world of first-born boys and second-born girls?

    2011-06-01

    Three Western studies have shown that male-to-female (MF) homosexual transsexuals tend to be born later than their siblings and to come from sibships with more brothers than sisters. The objective of this study was to determine whether these variables would be replicated in 530 MF and female-to-male (FM) Spanish transsexuals according to sexual orientation. The results showed that MF homosexual transsexuals had significantly more older brothers than the non-homosexual MF group. Compared with the expected rates in the general population, birth order was significantly higher in both MF (Slater's Index = 0.59; Fraternal Index = 0.61; Sororal Index = 0.58) and FM homosexual transsexuals (Slater's Index = 0.65; Fraternal Index = 0.68; Sororal Index = 0.67), and sibling sex ratio was significantly higher than expected in homosexual MF (sex ratio = 0.55) but not in homosexual FM transsexuals. No significant differences were found in the non-homosexual subgroups. The replication of the later birth order and sibling sex-ratio effect in MF homosexual transsexuals corroborates previous findings in a variety of groups from different cultures and may suggest a common mechanism underlying the etiology of transsexualism.

  4. Challenging stereotypes? The older woman in the TV series Brothers & Sisters.

    PubMed

    Oró-Piqueras, Maricel

    2014-12-01

    The TV series, Brothers & Sisters, broadcast from 2006 to 2011 by ABC (USA) and a year later by Channel 4 (UK) with quite high audience rates, starts when the patriarchal figure, William Walker, dies of a heart attack and two female figures around their sixties come center stage: his wife, Nora Walker, and his long-term lover, Holly Harper. Once the patriarchal figure disappears, the female characters regain visibility by entering the labor market and starting relationships with other men. In that sense, both protagonists experience aging as a time in which they are increasingly freed from social and family constraints. However, their roles as nurturers keep on bringing them back to the domestic space in which they are safe from being involved in uncomfortable and unsuitable situations. Drawing on previous studies on the representation of the older woman in fictional media, this article intends to discern to what extent stereotypes related to the older woman are challenged through the two main protagonists of a contemporary TV series.

  5. Effects of older brother-younger sister incest: a study of the dynamics of 17 cases.

    PubMed

    Laviola, M

    1992-01-01

    The purpose of this study was to explore the effects of older brother-younger sister incest from the perspective of the women who experienced it in childhood or adolescent years. Dynamics in the families-of-origin were also explored, as these related or contributed to the effects from the incest. Seventeen women were interviewed, using an in-depth, semi-structured interview. Four self-report objective instruments were also administered that measure dynamics in the family-of-origin and symptomatology that is often associated with the effects of trauma. Interview and objective data were analyzed by systematically organizing the women's perceptions and conceptualizations into common themes. All of the women's families of origin were described as dysfunctional. Common effects reported included mistrust of men and women, chronic low or negative self-esteem, sexual response difficulties, and intrusive thoughts of the incest. Women regarded individual therapy, talking with supportive family and friends, and validating themselves as victims at the time of the incest as ways in which they have helped themselves to deal with the effects of the incest. These results have important implications for therapy, including serious consideration of the impact and contribution of this kind of incest on reported symptomatology, and on emerging issues and conflicts in the therapeutic process.

    PubMed

    Oró-Piqueras, Maricel

    2014-12-01

    The TV series, Brothers & Sisters, broadcast from 2006 to 2011 by ABC (USA) and a year later by Channel 4 (UK) with quite high audience rates, starts when the patriarchal figure, William Walker, dies of a heart attack and two female figures around their sixties come center stage: his wife, Nora Walker, and his long-term lover, Holly Harper. Once the patriarchal figure disappears, the female characters regain visibility by entering the labor market and starting relationships with other men. In that sense, both protagonists experience aging as a time in which they are increasingly freed from social and family constraints. However, their roles as nurturers keep on bringing them back to the domestic space in which they are safe from being involved in uncomfortable and unsuitable situations. Drawing on previous studies on the representation of the older woman in fictional media, this article intends to discern to what extent stereotypes related to the older woman are challenged through the two main protagonists of a contemporary TV series.

    Video games can be played in many different contexts. This study examined associations between coplaying video games between siblings and levels of affection and conflict in the relationship. Participants were 508 adolescents (M age = 16.31 years of age, SD = 1.08) who completed questionnaires on video game use and sibling relationships. Participants were recruited from a large Northwestern city and a moderate city in the Mountain West of the United States. Video games played between siblings were coded by an independent sample to assess levels of physical aggression and prosocial behavior in each game. Playing video games with a sibling was associated with higher levels of sibling affection for both boys and girls, but higher levels of conflict for boys only. Playing a violent video game with a brother was associated with lower levels of conflict in the sibling relationship, whereas playing a prosocial video game was not related to any sibling outcome. The value of video games in sibling relationships will be discussed, with a focus on the type of game and the sex of the adolescent. PMID:26748076

  12. A test for evaluating the downscaling ability of one-way nested regional climate models: The Big-Brother Experiment

    NASA Astrophysics Data System (ADS)

    Denis, Bertrand

    The purpose of this thesis is to evaluate the downscaling ability of one-way nesting regional climate models (RCM). To do this, a rigorous and well-defined experiment for assessing the reliability of the one-way nesting approach is developed. This experiment, baptised the Big-Brother Experiment (BBE), is used for addressing some important one-way nesting issues. The first part of this work is dedicated to the development of a scale decomposition tool employed for the BBE. This tool involves a new spectral analysing technique suitable for two-dimensional fields on limited-area domains, and is based on the discrete cosine transform (DCT). It is used for degrading the spatial resolution of the lateral boundary conditions (LBC) used to drive the Canadian RCM (CRCM), for extracting mesoscale features from the atmospheric fields, and for regional validation, and producing power spectra. The second part of the thesis describes the BBE framework and its first results. The BBE consists in first establishing a reference virtual-reality climate from an RCM simulation using a large and high-resolution domain. This simulation is called the "Big Brother". This big-brother simulation is then degraded toward the resolution of today's global objective analyses (OA) and/or global climate models (GCM) by removing the short scales. The resulting fields are then used as nesting data to drive an RCM (called the "Little Brother") which is integrated at the same high-resolution as the Big Brother, but over a sub-area of the big-brother domain. The climate statistics of the Little Brother are then compared with those of the big-brother simulation over the little-brother domain. Differences between the two climates can thus be unambiguously attributed to errors associated with the dynamical downscaling technique, and not to model errors nor to observation limitations. The results for a February simulation shows that the Canadian RCM, using a factor of 6 between the model and the LBC spatial

  17. Considerations on domain location according to the jump of resolution between the driving data and the nested regional climate model within the Big-Brother experiment.

    2015-12-01

    Many studies have shown the importance of choosing the domain size adequately for dynamical downscaling with nested regional climate models. It is well known that domain should not be too large to avoid large departure from the driving data, and not be too small to provide sufficient distance from the lateral inflow to allow a full development of the small-scale features resolved by the increase resolution. Although practitioners of dynamical downscaling are well aware that the jump of resolution between the driving data and the nested regional climate model impacts the simulated climate, the issue has never been properly study. Larger is the jump of resolution, larger is the distance from the lateral inflow to fully develop the small-scale features permitted by the increase resolution. Our investigation compares direct nesting to achieve a grid mesh of 0.15o from driving data at 3.6°, 1.8o, 0.45° and 0.15° using the perfect-prognostic approach of the Big-Brother protocol. The results show that the small-scale transient-eddy component struggles to be fully developed with reduced resolution of the driving data. Overall, this study suggests that domain location (i.e. domain of interest or subsequent nested domains) must be chosen carefully according to the jump of resolution to allow the optimal development of small-scale features allowed by the increase resolution of the nested model.

    2013-01-01

    Retrospective data were entered anonymously by 1,521 adult women using a computer-assisted self-interview. Thirty-one participants were victims of sister-sister incest, 40 were victims of brother-sister incest, 19 were victims of father-daughter incest, 8 were victims of sexual abuse by an adult female (including one mother), and 232 were victims of sexual abuse by an adult male other than their father before reaching 18 years of age. The rest (1,203) served as controls. The victims of sister-sister incest had significantly more problematic outcomes than controls on many measures as adults. Victims of sister-sister incest were more depressed and more likely than controls to be distant from the perpetrator-sister and to have traded sex for money, experienced an unplanned pregnancy, engaged in four different types of masturbation, and engaged in 13 different same-sex behaviors. Our findings were consistent with other reports of early eroticization and persistent hypereroticization of incest victims.

  7. inv(9)(p24q13) in three sterile brothers.

    PubMed

    2000-01-01

    Only nine non-polymorphic constitutional pericentric inversions of chromosome 9 have been described. We report on a familial inv(9)(p24q13) associated with sterility in three brothers. The mother's chromosomes were normal in blood lymphocytes (n=130); the father was already deceased and his karyotype unknown. However, the presence of any of the maternal chromosomes 9 (as assessed by C-banding) in her carrier children is inconsistent with the assumption of maternal mosaicism. Two single sisters were also carriers. The same rearranged chromosome 9 in the three sterile brothers can hardly be regarded as a fortuitous association, especially when the breakpoints are almost identical to those of the sole inversion previously found in an azoospermic male. If their father was a carrier, the observed sterility may be the result of 'chromosome anticipation', a phenomenon already invoked for certain familial chromosomal rearrangements.

  8. Where are Sedna's Sisters?

    NASA Astrophysics Data System (ADS)

    Bartlett, D. F.

    2005-05-01

    Simulations of the formation of the Oort cloud from the Kuiper Belt typically are presented as an animated scatter diagram. Here the orbit of each object appears as a point of perihelion distance q and semi-major axis a. (eg. Levison, Morbidelli, & Dones 2004). These plots show a conspicuous void, bounded by the inequalities: q < a, q > 50 AU, and a < 5000-10000 AU. Brown (2005) calls this void the ``Bermuda Triangle". The only present occupant is Sedna (q=76 AU, a=501 AU). Brown, Trujillo, & Rabinowitz , the discovers of Sedna, have challenged others to explain how Sedna got inside the triangle and to predict where similar objects might be found. Sedna could not have simply formed in its current orbit by the accumulation of smaller objects (Stern 2005). Several authors have suggested that a passing star scattered Sedna into the triangle shortly after the birth of the solar system. Here I offer an alternative which uses the very strong galactic tidal forces of the Sinusoidal potential (Bartlett 2001, 2004). In this potential, the numerator of Newton's law is replaced by GM cos(ko r) where ko = 2 π / lambdao and the 'wavelength' λ o is 425 pc. The 20 radial oscillations between the sun and the center of the Galaxy give tidal forces that are 120 times as big as generally expected. I will show how this tidal force, acting over the lifetime of the solar system, could move the perihelion of Sedna from about 40 to 76 AU. Sedna's sisters are likely to have still larger q & a and to have perihelia in two specific quadrants of the ecliptic plane.

  9. Sisters in Dutch hospitals.

    PubMed

    van den Bergh-Braam, A H

    1985-11-01

    This study focuses on hospital sisters in 30 Dutch hospitals. The so-called role-set approach has been adopted. In this approach the sisters are the focal persons. Direct superiors, specialists, registered nurses and student nurses acted as role-senders. The possible number of respondents is 600 (120 of each group). The response of hospital sisters is 100%, that of role-senders 88%. The study started out as an attempt to collect background information on the causes of wastage of sisters. High wastage rates are generally regarded as an indication of an unfavourable working environment. Since hospital sisters occupy a key position in hospitals, the ward problems will be studied from their angle. Although wastage rates have dropped recently, it does not necessarily follow that the working environment has improved. Wastage is known to act as a safety valve, thus allowing tensions to resolve. The threat of unemployment clogs this outlet, which increases the tensions on the hospital ward. Data from the study show that work overload is one of the major stress factors for sisters. Analyses demonstrated that there exists a relationship between work overload and tensions with the management and direct superiors, tensions in job execution, irritableness on the ward, low self-esteem, health complaints and psychological condition. Sisters with an excessive job involvement refer to work overload more often than their moderate colleagues. There is a relationship between an unfavourable working environment and irritableness of sisters.

Block pumice suitable for commercial uses occurs at an undeveloped claim at Rock Mesa in the wilderness, but numerous other sources occur outside the wilderness closer to markets. A broad area centered around South Sister volcano is among the most favorable targets for geothermal resources in the Oregon Cascade Range, based on the very young age and large volume of silicic volcanic rocks that occur in this area. Deep exploration holes could be drilled in areas outside the wilderness south of South Sister to provide data on the subsurface thermal and hydrologic regimes in the southern part of the area most likely to contain geothermal resources.

    Two brothers (case 1 and case 2) with erythema nodosum were diagnosed with thromboangiitis obliterans (TAO). The patients were treated with compounds including Danshen Dripping Pills, Fufang Danshen Diwan and Salvia tetramethylpyrazine. The patients were also treated with fibro-blast growth factor to promote epidermal growth and Bayaspirin enteric-coated tablets to reduce platelet aggregation. The polysaccharide nucleic acid fraction of Bacillus Calmette-Guérin and compound glycyrrhizin tablets were taken to improve immune function. Following treatment, case 2 had reduced pain levels in the left foot. The ulcer on the first toe of the left foot had decreased in size, with a reduction in pus secretions and inflammation. Case 1 demonstrated a reduction in pus secretion from the ulcer. However, the area of the ulcer had increased, spreading to the fifth toe with gangrene. A tendon had become exposed on the right foot, which was broken and induced severe pain. PMID:24137181

    Two brothers had familial hypertrophic cardiomyopathy and vasospastic angina pectoris concurrently. Their family history showed that one of their sisters had hypertrophic cardiomyopathy and another brother died suddenly at age 52. The clinical diagnosis of hypertrophic cardiomyopathy was confirmed by an echocardiogram and left ventriculography. They had typical chest pain at rest, and a significant vasospasm of coronary arteries with chest pain and obvious ST-T changes in the electrocardiograms was provoked by intracoronary injection of acetylcholine in both patients. The administration of a calcium antagonist and nitrate was effective for ameliorating chest pain with no cardiovascular events during the follow up period of more than 3 years. Although underlying pathophysiologic abnormalities of familial hypertrophic cardiomyopathy and vasospastic angina pectoris are considered to be transmitted genetically, the genetic backgrounds of these cases remain to be clarified.

Participants were older (M = 10.8 years; SD = .46) and younger siblings (M = 8.4 years; SD = 1.13), and their parents (94% biological mothers), who were randomly assigned within school to the intervention (n = 28) or no-attention control (n = 26) condition. The intervention condition included 12 weekly afterschool sessions (90 min each) for sibling pairs and 3 family nights for parents and siblings (2 hr each). was designed to enhance sibling relationships via 2 primary intervention targets: (a) children's capacities that underlie positive sibling dynamics, including relationship skills, cognitions, and shared activities; and (b) parenting of siblings, specifically, enhancing positive guidance and involvement and discouraging authoritarian control. Pre- and posttest data were gathered from siblings and parents. Recruitment and implementation data revealed high rates of attendance and completion, and high ratings of parent satisfaction with the program. Further, analyses suggested the program had positive effects of small to modest magnitude on posttest measures of sibling and parent-child relationship quality, parenting of siblings, older siblings' emotional efficacy, and parents' depressive symptoms and parenting stress, controlling for pretest levels of all outcomes and family background characteristics.

    Using a randomized, intent-to-treat design, this pilot study examined the feasibility and short-term effects of () with a sample of 54 low-income Latino families (91% Mexican-origin). Participants were older (M = 10.8 years; SD = .46) and younger siblings (M = 8.4 years; SD = 1.13), and their parents (94% biological mothers), who were randomly assigned within school to the intervention (n = 28) or no-attention control (n = 26) condition. The intervention condition included 12 weekly afterschool sessions (90 min each) for sibling pairs and 3 family nights for parents and siblings (2 hr each). was designed to enhance sibling relationships via 2 primary intervention targets: (a) children's capacities that underlie positive sibling dynamics, including relationship skills, cognitions, and shared activities; and (b) parenting of siblings, specifically, enhancing positive guidance and involvement and discouraging authoritarian control. Pre- and posttest data were gathered from siblings and parents. Recruitment and implementation data revealed high rates of attendance and completion, and high ratings of parent satisfaction with the program. Further, analyses suggested the program had positive effects of small to modest magnitude on posttest measures of sibling and parent-child relationship quality, parenting of siblings, older siblings' emotional efficacy, and parents' depressive symptoms and parenting stress, controlling for pretest levels of all outcomes and family background characteristics. Discussion addresses the feasibility of sibling-focused programs with low-income Latino families and makes recommendations for future research. (PsycINFO Database Record PMID:27077238

    Toledo-Pereyra, Luis H

    2010-10-01

    Few in the history of surgery and just as few in the history of medicine can reach the level of clinical visibility as achieved by the Mayo brothers. The brothers changed the face of medicine while they were alive, and their fame and influence continued to grow after their death in 1939. The Mayo American surgical legacy had incredible proportions. The brothers systematically modified the field as few others had done before. They were great surgical innovators who took the surgical techniques of others and added a touch of their own to make the surgical procedure better and more secure. The Mayos were the stars regionally, nationally, and around the world. They attracted attention from their generation and occupied center stage long after. To speak of the Mayos is to speak of the quintessential American values of professionalism, respect, commitment, and caring for their fellow human beings. Their creation, the Mayo Clinic, surpassed the wildest hopes and predictions that anyone could have had regarding their best dreams. PMID:20874478

    2013-01-01

    This essay examines the life and work of Sir William Thornley Stoker, 1st Baronet (1845-1912), the eldest brother of Bram Stoker (1847-1912), the author of Dracula (1897). Sir William or "Thornley," as he was commonly known, was one of Ireland's leading physicians. He performed some of the first brain surgeries in Ireland using Sir David Ferrier's maps of the cerebral cortex. From 1879 into the twentieth century, Thornley served as inspector for Ireland under the 1876 Cruelty to Animals Act. In this role, Thornley was responsible for granting licenses to researchers who performed experiments on live animals. Due to his reservations about animal experimentation, Thornley eventually became an advocate for the antivivisection cause, testifying at the second Royal Commission on Vivisection (1906-1912). Thornley also influenced Irish literature, albeit indirectly. Bram Stoker's composition notes for Dracula show that he consulted his older brother about the medical scenes in his novel. Thornley's knowledge of cerebral localization and his animal rights advocacy both surface in Dracula.

  16. Holocentric plant meiosis: first sisters, then homologues.

    PubMed

    Heckmann, Stefan; Schubert, Veit; Houben, Andreas

    2014-01-01

    Meiosis is a crucial process of sexual reproduction by forming haploid gametes from diploid precursor cells. It involves 2 subsequent divisions (meiosis I and meiosis II) after one initial round of DNA replication. Homologous monocentric chromosomes are separated during the first and sister chromatids during the second meiotic division. The faithful segregation of monocentric chromosomes is realized by mono-orientation of fused sister kinetochores at metaphase I and by bi-orientation of sister kinetochores at metaphase II. Conventionally this depends on a 2-step loss of cohesion, along chromosome arms during meiosis I and at sister centromeres during meiosis II.

  3. Flow behavior in the Wright Brothers Facility

    NASA Technical Reports Server (NTRS)

    Genn, S.

    1984-01-01

    It has become increasingly apparent that a reexamination of the flow characteristics in the low speed Wright Brothers Facility (WBF) is of some importance in view of recent improvements in the precision of the data acquisition system. In particular, the existence of local regions of separation, if any, in back portions of the circuit, and possible related unsteadiness, are of interest. Observations from that initial experiment did indicate some unsteady air flow problems in the cross leg, and thereafter the test region (Section A) was calibrated quantitatively. The intent was to learn something about the effect of upstream intermittent behavior flow on the test section flow, as well as to provide an extensive calibration as a standard for the effects induced by future alteration of the tunnel. Distributions of total pressure coefficients were measured first at one cross-section plane of the test section, namely the model station. Data were obtained for several tunnel speeds. The reduced data yielded an unexpected distribution involving larger pressures along the inside wall.

  4. The Lehman Brothers effect and bankruptcy cascades

    NASA Astrophysics Data System (ADS)

    Sieczka, P.; Sornette, D.; Holyst, J. A.

    2011-08-01

    Inspired by the bankruptcy of Lehman Brothers and its consequences on the global financial system, we develop a simple model in which the Lehman default event is quantified as having an almost immediate effect in worsening the credit worthiness of all financial institutions in the economic network. In our stylized description, all properties of a given firm are captured by its effective credit rating, which follows a simple dynamics of co-evolution with the credit ratings of the other firms in our economic network. The dynamics resembles the evolution of Potts spin-glass with external global field corresponding to a panic effect in the economy. The existence of a global phase transition, between paramagnetic and ferromagnetic phases, explains the large susceptibility of the system to negative shocks. We show that bailing out the first few defaulting firms does not solve the problem, but does have the effect of alleviating considerably the global shock, as measured by the fraction of firms that are not defaulting as a consequence. This beneficial effect is the counterpart of the large vulnerability of the system of coupled firms, which are both the direct consequences of the collective self-organized endogenous behaviors of the credit ratings of the firms in our economic network.

    2013-09-01

    This report demonstrates the limits of DNA identification when siblings are involved. The Israeli DNA database routinely amplifies suspects samples using the PowerPlex(®) ESI16 system (Promega). While uploading a series of suspects into the database software, we found an unusual high number of shared alleles between two suspects 31 out of 32 alleles. Verification of their demographic data identified them as brothers. After confirmation of their paternity affiliation using the AmpFlSTR(®)YFiler™ (Applied Biosystems), we used two other multiplexes kits to improve the differentiation rate. The PowerPlex(®) ESX17 System (Promega) added one locus, SE33, who exhibits four different alleles. The second kit, the AmpFlSTR(®)MiniFiler™ (Applied Biosystems) added three more loci. Only one allele difference was found. In order to increase the discrimination power between related and unrelated individuals, we recommend that the DNA laboratories consider using a larger multiplex typing kit in cases like the one informed here.

  7. Eruptive history of South Sister, Oregon Cascades

    USGS Publications Warehouse

    Fierstein, J.; Hildreth, W.; Calvert, A.T.

    2011-01-01

    South Sister is southernmost and highest of the Three Sisters, three geologically dissimilar stratovolcanoes that together form a spectacular 20km reach along the Cascade crest in Oregon. North Sister is a monotonously mafic edifice as old as middle Pleistocene, Middle Sister a basalt-andesite-dacite cone built between 48 and 14ka, and South Sister is a basalt-free edifice that alternated rhyolitic and intermediate modes from 50ka to 2ka (largely contemporaneous with Middle Sister). Detailed mapping, 330 chemical analyses, and 42 radioisotopic ages show that the oldest exposed South Sister lavas were initially rhyolitic ~50ka. By ~37ka, rhyolitic lava flows and domes (72-74% SiO2) began alternating with radially emplaced dacite (63-68% SiO2) and andesite (59-63% SiO2) lava flows. Construction of a broad cone of silicic andesite-dacite (61-64% SiO2) culminated ~30ka in a dominantly explosive sequence that began with crater-forming andesitic eruptions that left fragmental deposits at least 200m thick. This was followed at ~27ka by growth of a steeply dipping summit cone of agglutinate-dominated andesite (56-60.5% SiO2) and formation of a summit crater ~800m wide. This crater was soon filled and overtopped by a thick dacite lava flow and then by >150m of dacitic pyroclastic ejecta. Small-volume dacite lavas (63-67% SiO2) locally cap the pyroclastic pile. A final sheet of mafic agglutinate (54-56% SiO2) - the most mafic product of South Sister - erupted from and drapes the small (300-m-wide) present-day summit crater, ending a summit-building sequence that lasted until ~22ka. A 20kyr-long-hiatus was broken by rhyolite eruptions that produced (1) the Rock Mesa coulee, tephra, and satellite domelets (73.5% SiO2) and (2) the Devils Chain of ~20 domes and short coulees (72.3-72.8% SiO2) from N-S vent alignments on South Sister's flanks. The compositional reversal from mafic summit agglutinate to recent rhyolites epitomizes the frequently changing compositional modes of the

    Discovers sisters' and charge nurses' thoughts about quality assurance and whether their needs and those of their patients were satisfied by the process. Reports the results of qualitative research conducted with sisters and charge nurses working within specific clinical areas in a community trust. Shows the differences of opinion within the sample towards quality and illustrates that, although sisters and charge nurses have a good knowledge of what quality is, they acknowledge that others working within their clinical areas may not be similarly aware. Finds that, while some of the respondents felt that quality assurance would benefit patients to some degree, others felt that quality initiatives actually disadvantaged patients. Members of the sample were unhappy with certain problems of quality assurance, associated with external and internal auditing, training needs and financial implications. Recommends that quality needs to be formally included in pre-and post-basic training.

    The position of Xenacoelomorpha in the tree of life remains a major unresolved question in the study of deep animal relationships. Xenacoelomorpha, comprising Acoela, Nemertodermatida, and Xenoturbella, are bilaterally symmetrical marine worms that lack several features common to most other bilaterians, for example an anus, nephridia, and a circulatory system. Two conflicting hypotheses are under debate: Xenacoelomorpha is the sister group to all remaining Bilateria (= Nephrozoa, namely protostomes and deuterostomes) or is a clade inside Deuterostomia. Thus, determining the phylogenetic position of this clade is pivotal for understanding the early evolution of bilaterian features, or as a case of drastic secondary loss of complexity. Here we show robust phylogenomic support for Xenacoelomorpha as the sister taxon of Nephrozoa. Our phylogenetic analyses, based on 11 novel xenacoelomorph transcriptomes and using different models of evolution under maximum likelihood and Bayesian inference analyses, strongly corroborate this result. Rigorous testing of 25 experimental data sets designed to exclude data partitions and taxa potentially prone to reconstruction biases indicates that long-branch attraction, saturation, and missing data do not influence these results. The sister group relationship between Nephrozoa and Xenacoelomorpha supported by our phylogenomic analyses implies that the last common ancestor of bilaterians was probably a benthic, ciliated acoelomate worm with a single opening into an epithelial gut, and that excretory organs, coelomic cavities, and nerve cords evolved after xenacoelomorphs separated from the stem lineage of Nephrozoa.

  18. A Unique Case of Allogeneic Fat Grafting Between Brothers

    Summary: We present a case of a 65-year-old man with cutaneous T-cell lymphoma treated with radiation therapy and an allogeneic hematopoietic stem cell transplant from his human leukocyte antigen-matched brother. Engraftment was successful, but the patient went on to develop painful, radiation-induced ulcers. The ulcers were fat-allografted using liposuctioned fat from his brother because of the patient’s unique chimeric state. Postprocedure follow-up revealed epithelialization of the ulcer sites and significant improvement in neuropathic pain. Our unique case study supports the use of fat grafting for its restorative purposes and for its ability to alleviate chronic neuropathic pain. Additionally, it appears that our case provides a basis of a general approach to the treatment of radiation-induced ulcers in chimeric patients with lymphoid malignancies. PMID:27757347

    Brown and polar bears have become prominent examples in phylogeography, but previous phylogeographic studies relied largely on maternally inherited mitochondrial DNA (mtDNA) or were geographically restricted. The male-specific Y chromosome, a natural counterpart to mtDNA, has remained underexplored. Although this paternally inherited chromosome is indispensable for comprehensive analyses of phylogeographic patterns, technical difficulties and low variability have hampered its application in most mammals. We developed 13 novel Y-chromosomal sequence and microsatellite markers from the polar bear genome and screened these in a broad geographic sample of 130 brown and polar bears. We also analyzed a 390-kb-long Y-chromosomal scaffold using sequencing data from published male ursine genomes. Y chromosome evidence support the emerging understanding that brown and polar bears started to diverge no later than the Middle Pleistocene. Contrary to mtDNA patterns, we found 1) brown and polar bears to be reciprocally monophyletic sister (or rather brother) lineages, without signals of introgression, 2) male-biased gene flow across continents and on phylogeographic time scales, and 3) male dispersal that links the Alaskan ABC islands population to mainland brown bears. Due to female philopatry, mtDNA provides a highly structured estimate of population differentiation, while male-biased gene flow is a homogenizing force for nuclear genetic variation. Our findings highlight the importance of analyzing both maternally and paternally inherited loci for a comprehensive view of phylogeographic history, and that mtDNA-based phylogeographic studies of many mammals should be reevaluated. Recent advances in sequencing technology render the analysis of Y-chromosomal variation feasible, even in nonmodel organisms.

  1. Big Surveys, Big Data Centres

    NASA Astrophysics Data System (ADS)

    Schade, D.

    2016-06-01

    Well-designed astronomical surveys are powerful and have consistently been keystones of scientific progress. The Byurakan Surveys using a Schmidt telescope with an objective prism produced a list of about 3000 UV-excess Markarian galaxies but these objects have stimulated an enormous amount of further study and appear in over 16,000 publications. The CFHT Legacy Surveys used a wide-field imager to cover thousands of square degrees and those surveys are mentioned in over 1100 publications since 2002. Both ground and space-based astronomy have been increasing their investments in survey work. Survey instrumentation strives toward fair samples and large sky coverage and therefore strives to produce massive datasets. Thus we are faced with the "big data" problem in astronomy. Survey datasets require specialized approaches to data management. Big data places additional challenging requirements for data management. If the term "big data" is defined as data collections that are too large to move then there are profound implications for the infrastructure that supports big data science. The current model of data centres is obsolete. In the era of big data the central problem is how to create architectures that effectively manage the relationship between data collections, networks, processing capabilities, and software, given the science requirements of the projects that need to be executed. A stand alone data silo cannot support big data science. I'll describe the current efforts of the Canadian community to deal with this situation and our successes and failures. I'll talk about how we are planning in the next decade to try to create a workable and adaptable solution to support big data science.

    Web-based training is frequently used by organizations as a convenient and low-cost way to teach employees new knowledge and skills. As web-based training is typically unproctored, employees may be held accountable to the organization by computer software that monitors their behaviors. The current study examines how the introduction of electronic performance monitoring may provoke negative emotional reactions and decrease learning among certain types of e-learners. Through motivated action theory and trait activation theory, we examine the role of performance goal orientation when e-learners are exposed to asynchronous and synchronous monitoring. We show that some e-learners are more susceptible than others to evaluation apprehension when they perceive their activities are being monitored electronically. Specifically, e-learners higher in avoid performance goal orientation exhibited increased evaluation apprehension if they believed asynchronous monitoring was present, and they showed decreased skill attainment as a result. E-learners higher on prove performance goal orientation showed greater evaluation apprehension if they believed real-time monitoring was occurring, resulting in decreased skill attainment.

  10. An incest case with three biological brothers as alleged fathers: Even 22 autosomal STR loci analysis would not suffice without the mother.

    2016-07-01

    Here, we report an incest paternity case involving three biological brothers as alleged fathers (AFs), their biological sister and her child that was investigated using the Investigator ESSplex Plus, AmpFLSTR Identifiler Plus/Investigator IDplex Plus and PowerPlex 16 kits. Initial duo paternity investigations using 15-loci autosomal short tandem repeat (STR) analyses failed to exclude any of the AFs. Despite the fact that one of the brothers, AF1, had a mismatch with the child at a single locus (D2S1338), the possibility of a single-step mutation could not be ruled out. When the number of autosomal STR loci analysed was increased to 22 without the inclusion of the mother, AF2 and AF3 still could not be excluded, since both of them again had no mismatches with the child. A breakthrough was possible only upon inclusion of the mother so that trio paternity investigations were carried out. This time AF1 and AF2 could be excluded at two loci (D2S1338 and D1S1656) and six loci (vWa, D1S1656, D12S391, FGA, PENTA E and PENTA D), respectively, and AF3 was then the only brother who could not be excluded from paternity. Subsequent statistical analyses suggested that AF3 could be the biological father of the child with a combined paternity index >100 billion and a probability of paternity >99.99999999%. These findings consolidate the fact that complex paternity cases such as those involving incest could benefit more from the inclusion of the mother than simply increasing the number of STR loci analysed.

    Treacher Collins syndrome (TCS) is associated with an abnormal differentiation of the first and second pharyngeal arches during fetal development. This causes mostly craniofacial deformities, which require numerous corrective surgeries. TCS is an autosomal dominant disorder and it occurs in the general population at a frequency of 1 in 50,000 live births. The syndrome is caused by mutations in the TCOF1 gene, which encodes the serine/alanine-rich protein named Treacle. Over 120 mutations of the TCOF1 gene responsible for TCS have been described. About 70% of recognized mutations are deletions, which lead to a frame shift, formation of a termination codon, and shortening of the protein product of the gene. Herewith, a new heterozygotic insertion, c.484_668ins185bp, was described in two monozygotic twin sisters suffering from TCS. This mutation was absent in their father, brother, and uncle, indicating a de novo origin. The insertion causes a shift in the reading frame and premature termination of translation at 167 aa. The novel insertion is the longest ever found in the TCOF1 gene and the only one found among monozygotic twin sisters.

    The EarthLabs project provides a framework to enhance high school students' climate literacy and awareness of climate change. The project provides climate science curriculum and teacher professional development, followed by research on students' learning as teachers implement EarthLabs climate modules in the classroom. The professional development targets high school teachers whose professional growth is structured around exposure to current climate science research, data observation collection and analysis. During summer workshops in Texas and Mississippi, teachers work through the laboratories, experiments, and hand-on activities developed for their students. In summer 2013, three graduate students from the University of Texas at Austin Institute for Geophysics with expertise in climate science participated in two weeklong workshops. The graduate students partnered with exemplary teacher leaders to provide scientific content and lead the EarthLabs learning activities. As an experiment, we integrated a visit to the Blanton Museum and an associated activity in order to motivate participants to think creatively, as well as analytically, about science. This exercise was inspired by the work and educational philosophy of Sister Corita Kent. During the visit to the Blanton Museum, we steered participants towards specific works of art pre-selected to emphasize aspects of the climate of Texas and to draw participants' attention to ways in which artists convey different concepts. For example, artists use of color, lines, and symbols conjure emotional responses to imagery in the viewer. The second part of the exercise asked participants to choose a climate message and to convey this through a collage. We encouraged participants to combine their experience at the museum with examples of Sister Corita Kent's artwork. We gave them simple guidelines for the project based on techniques and teaching of Sister Corita Kent. Evaluation results reveal that participants enjoyed the

    2004-02-01

    Orville and Wilbur Wright of Dayton, OH, not only were the first to fly a powered aircraft, but also pioneered many human factors considerations. While others tried to develop aircraft with a high degree of aerodynamic stability, the Wrights intentionally designed unstable aircraft with "cerebralized" control modeled on bird flight. During 1901-03, the brothers worked with large gliders at Kill Devil Hills, near Kitty Hawk, NC, to develop the first practical human-interactive controls for aircraft pitch, roll, and yaw. On December 17, 1903, they made four controlled, powered flights over the dunes at Kitty Hawk with their Wright Flyer. During the next 2 yr, the Wrights made numerous flights in the Wright Flyers II and III at Huffman Prairie near Dayton. They later developed practical in-flight control of engine power, plus an angle-of-attack sensor and stick-pusher that reduced pilot workload. The brothers' flight demonstrations in the U.S. and Europe during 1908-09 awakened the world to the new age of controlled flight. Orville was the first aviator to use a seat belt. He also introduced a rudder boost/trim control that gave the pilot greater control authority. The Wrights' flight training school in Dayton included a flight simulator of their own design. The Wrights patented their practical airplane and flight control concepts, many of which are still in use today.

    The clinical, radiological, and neuropathological findings in early onset Cockayne syndrome are illustrated in identical twins and their brother. Their appearance of dwarfism with small head and prominent beaked nose strongly resembled that seen in the Seckel syndrome, but unlike patients with that syndrome they had a normal birth weight (for twins), thick cranial vaults, intracranial calcification, and a severe degree of mental retardation. The twins were deaf and blind, with optic atrophy and retinal pigmentation, while their brother had cataracts. Their hands and feet were large in proportion to their small trunk. They had cutaneous sensitivity to any slight exposure to ultraviolet light and severe neurologic problems with incoordination and spasticity. Radiologic findings included microcephaly, a thick cranial vault, a small pelvis, coxa valga, and "ivory epiphyses" in terminal phalanges of hands and feet. Pathologic findings included atrophy of white matter with widespread patchy demyelination, and massive siderocalcific deposits in the brain, particularly in the basal ganglia and cerebellum. While autosomal recessive inheritance is most likely, formally X-linked inheritance cannot be excluded. PMID:6890311

    2013-09-01

    Osteochondritis dissecans is a disorder of unknown etiology that can result in fragmentation of osteochondral surfaces, most commonly of the knee, shoulder, elbow, and ankle. This may lead to sequelae of pain and an inability to participate in desired activities. Multiple theories exist as to the true cause of the disorder, but none have been fully proven. One such proposed etiology is genetic causation. Familial cases of osteochondritis dissecans are rare, yet these cases offer support to growing evidence that may support a genetic link. This article describes osteochondritis dissecans lesions of the femoral trochlea in monozygotic (identical) twins. Both twins presented with similar symptoms 1 year apart. Neither twin had any clear inciting trauma. Magnetic resonance imaging revealed osteochondral lesions in similar positions of the lateral trochlear of the same knee in both brothers. Osteochondral autograft transfer and tibial tubercle anteromedialization were performed on both patients. An identical postoperative protocol was followed, and recovery with full return to sport was comparable for the brothers. To the authors' knowledge, only 1 other case report exists of osteochondritis dissecans lesions in monozygotic twins. Although debate continues regarding the true etiology of this disorder, cases of identical twins presenting with a similar disease process are highly suggestive of a genetic component and may lead to early identification and treatment of these lesions. Continued research in the area of osteochondritis dissecans and its genetic basis is needed to completely understand this disorder. PMID:24025016

    1997-04-01

    On the basis of social modeling theory and a sibling interaction hypothesis, it was hypothesized that specific relationship qualities between a pregnant or parenting teen and her younger sister would be associated with permissive younger sister outcomes, such as permissive childbearing attitudes and permissive sexual behavior. Results indicated that negative relationship qualities, such as rivalry, competition, and conflict, were more closely related to younger sisters engaging in problem delinquent-like behavior and sexual behavior than were positive relationship qualities, such as warmth and closeness. Additionally, a shared friendship network with the older sister was found to be associated with extensive younger sister problem behavior and sexual behavior. Three potential explanatory processes are discussed.

    Sponsored by Associated Universities, Inc. (AUI) and the National Radio Astronomy Observatory (NRAO), this project creates a cultural and educational exchange program between communities in South and North America, linking San Pedro de Atacama in Chile and Magdalena, New Mexico in the United States. Both communities have similar demographics, are in relatively undeveloped regions of high-elevation desert, and are located near major international radio astronomy research facilities. The Atacama Large Millimeter/submillimeter Array (ALMA) is just 40 km east of San Pedro; the Very Large Array (VLA) is just 40 km west of Magdalena. In February 2007, the Mayor of San Pedro and two teachers visited Magdalena for two weeks; in July 2007 three teachers from Magdalena will visit San Pedro. These visits enable the communities to lay the foundation for a permanent, unique partnership. The teachers are sharing expertise and teaching methodologies for physics and astronomy. In addition to creating science education opportunities, this project offers students linguistic and cultural connections. The town of San Pedro, Chile, hosts nearly 100,000 tourists per year, and English language skills are highly valued by local students. Through exchanges enabled by email and distance conferencing, San Pedro and Magdalena students will improve English and Spanish language skills while teaching each other about science and their respective cultures. This poster describes the AUI/NRAO Sister Cities program, including the challenges of cross-cultural communication and the rewards of interpersonal exchanges between continents and cultures.

  6. Horsetails are the sister group to all other monilophytes and Marattiales are sister to leptosporangiate ferns.

    The "Monilophyte" clade comprising ferns, horsetails and whisk ferns receives unequivocal support from molecular data as the sister clade to seed plants. However, the branching order of its earliest emerging lineages, the Equisetales (horsetails), the Marattiales, the Ophioglossales/Psilotales and the large group of leptosporangiate ferns has remained dubious. We investigated the mitochondrial nad2 and rpl2 genes as two new, intron-containing loci for a wide sampling of taxa. We found that both group II introns - nad2i542g2 and rpl2i846g2 - are universally present among monilophytes. Both introns have orthologues in seed plants where nad2i542g2 has evolved into a trans-arrangement. In contrast and despite substantial size extensions to more than 5kb in Psilotum, nad2i542g2 remains cis-arranged in the monilophytes. For phylogenetic analyses, we filled taxonomic gaps in previously investigated mitochondrial (atp1, nad5) and chloroplast (atpA, atpB, matK, rbcL, rps4) loci and created a 9-gene matrix that also included the new mitochondrial nad2 and rpl2 loci. We extended the taxon sampling with two taxa each for all land plant outgroups (liverworts, mosses, hornworts, lycophytes and seed plants) to minimize the risk of phylogenetic artefacts. We ultimately obtained a well-supported molecular phylogeny placing Marattiales as sister to leptosporangiate ferns and horsetails as sister to all remaining monilophytes. In addition, an indel in an exon of the here introduced rpl2 locus independently supports the placement of horsetails. We conclude that under dense taxon sampling, phylogenetic information from a prudent choice of loci is currently superior to character-rich phylogenomic approaches at low taxon sampling. As here shown the selective choice of loci and taxa enabled us to resolve the long-enigmatic diversifications of the earliest monilophyte lineages.

We investigated the mitochondrial nad2 and rpl2 genes as two new, intron-containing loci for a wide sampling of taxa. We found that both group II introns - nad2i542g2 and rpl2i846g2 - are universally present among monilophytes. Both introns have orthologues in seed plants where nad2i542g2 has evolved into a trans-arrangement. In contrast and despite substantial size extensions to more than 5kb in Psilotum, nad2i542g2 remains cis-arranged in the monilophytes. For phylogenetic analyses, we filled taxonomic gaps in previously investigated mitochondrial (atp1, nad5) and chloroplast (atpA, atpB, matK, rbcL, rps4) loci and created a 9-gene matrix that also included the new mitochondrial nad2 and rpl2 loci. We extended the taxon sampling with two taxa each for all land plant outgroups (liverworts, mosses, hornworts, lycophytes and seed plants) to minimize the risk of phylogenetic artefacts. We ultimately obtained a well-supported molecular phylogeny placing Marattiales as sister to leptosporangiate ferns and horsetails as sister to all remaining monilophytes. In addition, an indel in an exon of the here introduced rpl2 locus independently supports the placement of horsetails. We conclude that under dense taxon sampling, phylogenetic information from a prudent choice of loci is currently superior to character-rich phylogenomic approaches at low taxon sampling. As here shown the selective choice of loci and taxa enabled us to resolve the long-enigmatic diversifications of the earliest monilophyte lineages. PMID:25999055

  8. Snapping annular ligament of the elbow joint in the throwing arms of young brothers.

    We examined young brothers with symptomatic snapping elbow in the throwing arm. Arthroscopic examination confirmed the mechanism of snapping, in which loose and protruded annular ligament-like tissue covered the volar half of the radial head in elbow extension and uncovered the radial head in deep elbow flexion. Arthroscopic resection of the annular ligament-like tissue was performed in one brother. Histologic examination of the removed tissue showed degenerated ligament tissue. Excision of loose annular ligament abolished snapping. Contralateral elbows of the brothers also showed similar asymptomatic snapping. Researchers suggest that a hereditary factor contributing to loose annular ligament and repetitive microtrauma from throwing is the cause of symptoms.

  9. Developing skills in clinical leadership for ward sisters.

    PubMed

    Fenton, Katherine; Phillips, Natasha

    The Francis report has called for a strengthening of the ward sister's role. It recommends that sisters should operate in a supervisory capacity and should not be office bound. Effective ward leadership has been recognised as being vital to high-quality patient care and experience, resource management and interprofessional working. However, there is evidence that ward sisters are ill equipped to lead effectively and lack confidence in their ability to do so. University College London Hospitals Foundation Trust has recognised that the job has become almost impossible in increasingly large and complex organisations. Ward sisters spend less than 40% of their time on clinical leadership and the trust is undertaking a number of initiatives to support them in this role.

    Production of healthy gametes requires a reductional meiosis I division in which replicated sister chromatids comigrate, rather than separate as in mitosis or meiosis II. Fusion of sister kinetochores during meiosis I may underlie sister chromatid comigration in diverse organisms, but direct evidence for such fusion has been lacking. We used laser trapping and quantitative fluorescence microscopy to study native kinetochore particles isolated from yeast. Meiosis I kinetochores formed stronger attachments and carried more microtubule-binding elements than kinetochores isolated from cells in mitosis or meiosis II. The meiosis I-specific monopolin complex was both necessary and sufficient to drive these modifications. Thus, kinetochore fusion directs sister chromatid comigration, a conserved feature of meiosis that is fundamental to Mendelian inheritance.

    1997-01-01

    A case report of three sisters with different degrees of septate uteri, a rare familial aggregation, is presented. The youngest sister was diagnosed with a complete uterine septum with cervical duplication and complete longitudinal vaginal septum. She also had a bilateral partial ureteral duplication. Investigation of the family showed that the eldest sister had a complete uterine septum and her pregnancy had terminated with a vaginal delivery following premature rupture of the membranes. The asymptomatic middle sister showed an incomplete uterine septum. Finally, the mother was normal with respect to urogenital anatomy. These types of Müllerian anomalies cannot be explained by the classical theory of unidirectional Müllerian duct development; the alternative bidirectional theory is proposed instead. Additionally, the results are suggestive that the prevalence of major uterine malformations may be higher than generally thought, due to asymptomatic cases.

    Moore, Charles B.

    The first hot air balloon ascension over Paris in September 1783 has been described so many times that it and its passengers—the sheep, the rooster, and the duck—have joined Benjamin Franklin and his kite in the folklore of our culture. Not so well known is the earlier history of ballooning; that the brothers Montgolfier had demonstrated their hot air balloons repeatedly for several months prior to the ascent over Paris; or that the physicist Charles, urged onward and financed by an enthusiast, Barthélemy Faujas de Saint-Fond, launched successfully the first fabric balloon filled with hydrogen over Paris more than 3 weeks prior to the memorable ascent of the sheep, and rooster, and the duck.For all of its well-documented detail, the book is readable and enjoyable. It is a well-written but complex book in which Professor Gillispie develops a number of subjects to recreate the era in perspective. The origins and the disposition of the Montgolfiers, the industry of the period, the idea of capturing heated air are all reported in detail. The attempts to obtain government funding and the promotional activities in Paris were forerunners of the modern techniques for obtaining support of research activities.

  5. Brother is high Sr/Y two-mica granite and sister is leucogranite: twin granites in the Northern Himalayan Gneiss Domes, southern Tibet

    NASA Astrophysics Data System (ADS)

    Zeng, L.; Gao, L.; Xie, K.

    2011-12-01

    Leucogranites in the Himalayan orogen is widely considered as the type example of crustal melts, which provides a probe to investigate the interplay among high-grade metamorphism, crustal anatexis, and tectonic transition in large-scale collisional belts. Whether the leucogranite was a daughter product from a more primitive granitic melt is an interesting question that deserves careful examination to address the above issue. We report a new suite of two-mica granite (TMG) and leucogranite (LG) in the Yardoi gneiss dome (YGD) in the easternmost of the Northern Himalayan Gneiss Domes (NHGD), south of the Yarlung-Tsangpo suture. SHRIMP and LA-ICP-MS zircon U/Pb dating show that TMG and LG formed at ~17.7 Ma to ~20.0 Ma and at ~17.1 Ma, respectively. Both suites of granite have high Na/K (>1.30) ratios. The TMGs are characterized by (1) high Sr (>450 ppm), low Rb (<95 ppm) and Y (<6 ppm), and high Sr/Y (>86) ratios; (2) no Eu anomalies; and (3) low initial 87Sr/86Sr ratios (<0.7098) and higher ɛNd (>-8.5) values. In contrast, the LGs have (1) lower Sr (<130 ppm) and higher Rb (92-130 ppm); (2) pronounced negative Eu anomalies with Eu/Eu*<0.55; and (3) relatively higher Sr (87Sr/86Sr(t) =0.7136-0.7148) and unradiogenic Nd (ɛNd(t)=-7.7~-11.1). These data demonstrate that these Mid-Miocene granites have major and trace element and radiogenic isotope compositions similar to those of >35 Ma granites, but significantly different from those granites of similar ages in the High Himalaya as well as in the NHGD. High Sr/Y and relatively unradiogenic Sr isotope compositions in the TMGs could be derived from partial melting of mafic materials formed during previous compressional thickening event which was triggered by the input of juvenile heat and material associated with the Miocene E-W extension. An AFC process (plagioclase fractional crystallization and contamination by crustal materials) could be a primary factor leading to the formation of these LGs. Concurrence of high Sr/Y granites and leucogranites in NHGD indicates that the Miocene rifting could have played an important but previously unrecognized role in producing the Himalayan leucogranite. Similarly, the ~43-44 Ma high Sr/Y two-mica granites were also accompanied by the formation of typical leucogranite. However, the Mid-Eocene suite was derived from melting of lower crustal mafic materials at overthickened crustal conditions. Concurrence of high Sr/Y granites and typical leucogranites in the NHGD demonstrates that leucogranites could be derived from more primitive granitic melts by AFC process.

  9. Volcano hazards in the Three Sisters region, Oregon

    2001-01-01

    Three Sisters is one of three potentially active volcanic centers that lie close to rapidly growing communities and resort areas in Central Oregon. Two types of volcanoes exist in the Three Sisters region and each poses distinct hazards to people and property. South Sister, Middle Sister, and Broken Top, major composite volcanoes clustered near the center of the region, have erupted repeatedly over tens of thousands of years and may erupt explosively in the future. In contrast, mafic volcanoes, which range from small cinder cones to large shield volcanoes like North Sister and Belknap Crater, are typically short-lived (weeks to centuries) and erupt less explosively than do composite volcanoes. Hundreds of mafic volcanoes scattered through the Three Sisters region are part of a much longer zone along the High Cascades of Oregon in which birth of new mafic volcanoes is possible. This report describes the types of hazardous events that can occur in the Three Sisters region and the accompanying volcano-hazard-zonation map outlines areas that could be at risk from such events. Hazardous events include landslides from the steep flanks of large volcanoes and floods, which need not be triggered by eruptions, as well as eruption-triggered events such as fallout of tephra (volcanic ash) and lava flows. A proximal hazard zone roughly 20 kilometers (12 miles) in diameter surrounding the Three Sisters and Broken Top could be affected within minutes of the onset of an eruption or large landslide. Distal hazard zones that follow river valleys downstream from the Three Sisters and Broken Top could be inundated by lahars (rapid flows of water-laden rock and mud) generated either by melting of snow and ice during eruptions or by large landslides. Slow-moving lava flows could issue from new mafic volcanoes almost anywhere within the region. Fallout of tephra from eruption clouds can affect areas hundreds of kilometers (miles) downwind, so eruptions at volcanoes elsewhere in the

  10. Sister chromatid segregation in meiosis II: deprotection through phosphorylation.

    PubMed

    Wassmann, Katja

    2013-05-01

    Meiotic divisions (meiosis I and II) are specialized cell divisions to generate haploid gametes. The first meiotic division with the separation of chromosomes is named reductional division. The second division, which takes place immediately after meiosis I without intervening S-phase, is equational, with the separation of sister chromatids, similar to mitosis. This meiotic segregation pattern requires the two-step removal of the cohesin complex holding sister chromatids together: cohesin is removed from chromosome arms that have been subjected to homologous recombination in meiosis I and from the centromere region in meiosis II. Cohesin in the centromere region is protected from removal in meiosis I, but this protection has to be removed--deprotected--for sister chromatid segregation in meiosis II. Whereas the mechanisms of cohesin protection are quite well understood, the mechanisms of deprotection have been largely unknown until recently. In this review I summarize our current knowledge on cohesin deprotection.

    Long noncoding RNAs (lncRNAs) are involved in diverse cellular processes through multiple mechanisms. Here, we describe a previously uncharacterized human lncRNA, CONCR (cohesion regulator noncoding RNA), that is transcriptionally activated by MYC and is upregulated in multiple cancer types. The expression of CONCR is cell cycle regulated, and it is required for cell-cycle progression and DNA replication. Moreover, cells depleted of CONCR show severe defects in sister chromatid cohesion, suggesting an essential role for CONCR in cohesion establishment during cell division. CONCR interacts with and regulates the activity of DDX11, a DNA-dependent ATPase and helicase involved in DNA replication and sister chromatid cohesion. These findings unveil a direct role for an lncRNA in the establishment of sister chromatid cohesion by modulating DDX11 enzymatic activity. PMID:27477908

    Brothers Seamount, a submarine volcano located along the Kermadec-Tonga Arc in New Zealand, results from intraoceanic plate subduction and as such, exhibits substantially different chemistries to those found on mid-ocean spreading ridges. Furthermore, Brothers Seamount has two major venting sites that exhibit disparate geochemistries. Combined, these factors suggest that microbial diversity studies of Brothers Volcano have potential to identify an array of novel microbial species. Two manned submarine expeditions, the first in November 2004 with the JAMSTEC R/V Yokosuka and Shinkai 6500 and the second in April/May 2005 with the HURL R/V Kiamikai-o-Kanaloa and Picses V dove on the Brothers Seamount a total of 9 times collecting vent, sediment and fluid samples used, in part, for microbial enrichments and molecular diversity studies. Clone libraries of the 16S rRNA gene were generated using DNA extracts from multiple samples at the two venting sites on Brothers Volcano. So far, more than 60 unique bacterial sequence types have been found out of an overall clone count of greater than 200 including , a, and -Proteobacteria, and several Planctomycetes. The -Proteobacteria account for most of the diversity. Archaeal 16S rRNA clone banks, including amplifications using primers specific for the phylum Nanoarchaeota, are currently being constructed, with preliminary results showing a diverse range of archaeal species.

    2016-04-01

    Spatially controlled release of sister chromatid cohesion during progression through the meiotic divisions is of paramount importance for error-free chromosome segregation during meiosis. Cohesion is mediated by the cohesin protein complex and cleavage of one of its subunits by the endoprotease separase removes cohesin first from chromosome arms during exit from meiosis I and later from the pericentromeric region during exit from meiosis II. At the onset of the meiotic divisions, cohesin has also been proposed to be present within the centromeric region for the unification of sister centromeres into a single functional entity, allowing bipolar orientation of paired homologs within the meiosis I spindle. Separase-mediated removal of centromeric cohesin during exit from meiosis I might explain sister centromere individualization which is essential for subsequent biorientation of sister centromeres during meiosis II. To characterize a potential involvement of separase in sister centromere individualization before meiosis II, we have studied meiosis in Drosophila melanogaster males where homologs are not paired in the canonical manner. Meiosis does not include meiotic recombination and synaptonemal complex formation in these males. Instead, an alternative homolog conjunction system keeps homologous chromosomes in pairs. Using independent strategies for spermatocyte-specific depletion of separase complex subunits in combination with time-lapse imaging, we demonstrate that separase is required for the inactivation of this alternative conjunction at anaphase I onset. Mutations that abolish alternative homolog conjunction therefore result in random segregation of univalents during meiosis I also after separase depletion. Interestingly, these univalents become bioriented during meiosis II, suggesting that sister centromere individualization before meiosis II does not require separase.

This process impinges between the tibia and calcaneus during deep forced plantar flexion. If this occurs it is called posterior ankle impingement syndrome. We report the case of 2 athletic monozygotic twin brothers with bony impingement posteriorly in the left ankle. Treatment consisted of ankle arthroscopy in both patients during which the symptomatic process was easily removed. At 3 months after surgery, both patients were completely free of pain, and 1 of the brothers had already returned to sports. The posterior ankle impingement syndrome is not a rare syndrome, but it has not been described in siblings thus far. That these 2 patients are monozygotic twin brothers suggests that genetics could play a role in the development of skeletal deformities that can result in posterior ankle impingement syndrome.

    1990-01-01

    We report 2 cases of type I glycogen storage disease (Von Gierke's disease) discovered in 2 brothers at the age of 7 and 5 years, respectively. Both developed hepatic adenoma at the age of 19 and 17. Hepatocellular carcinoma occurred in the older brother the discovery of adenoma 4 years after. The frequency of these tumors in patients with type I glycogen storage disease raises problems concerning the treatment and modality of regular surveillance of the liver in these patients. The policy for the detection and treatment of these tumors, and particularly the indications for liver transplantation are discussed. PMID:2155841

    2013-01-01

    Congenital insensitivity to pain with anhidrosis is an autosomal recessive disorder caused by mutations in the neurotrophic tyrosine receptor kinase 1 (NTRK1) gene, which encodes the receptor for nerve growth factor. We report the clinical and radiological pitfalls in the diagnosis and treatment of two brothers, aged 5 and 8 years, with congenital insensitivity to pain with anhidrosis, the older brother having a proven NTRK1 mutation. In the neonatal period, both presented with recurrent episodes of fever of unknown origin, but their clinical problems changed later. In addition to severe mental retardation and self-harming behaviour, the older brother developed recurrent nonbacterial destructive infections of both the calcaneus and later the talus. No immunodeficiency was found. The younger brother had three complex fractures with a long history of healing problems: overwhelming production of callus, osteomyelitis and movement restrictions. He has less mental retardation than his older brother and shows no self-mutilation.

  9. Geologic map of Three Sisters volcanic cluster, Cascade Range, Oregon

    2012-01-01

    The cluster of glaciated stratovolcanoes called the Three Sisters—South Sister, Middle Sister, and North Sister—forms a spectacular 20-km-long reach along the crest of the Cascade Range in Oregon. The three eponymous stratocones, though contiguous and conventionally lumped sororally, could hardly display less family resemblance. North Sister (10,085 ft), a monotonously mafic edifice at least as old as 120 ka, is a glacially ravaged stratocone that consists of hundreds of thin rubbly lava flows and intercalated falls that dip radially and steeply; remnants of two thick lava flows cap its summit. Middle Sister (10,047 ft), an andesite-basalt-dacite cone built between 48 and 14 ka, is capped by a thick stack of radially dipping, dark-gray, thin mafic lava flows; asymmetrically glaciated, its nearly intact west flank contrasts sharply with its steep east face. Snow and ice-filled South Sister is a bimodal rhyolitic-intermediate edifice that was constructed between 50 ka and 2 ka; its crater (rim at 10,358 ft) was created between 30 and 22 ka, during the most recent of several explosive summit eruptions; the thin oxidized agglutinate that mantles its current crater rim protects a 150-m-thick pyroclastic sequence that helped fill a much larger crater. For each of the three, the eruptive volume is likely to have been in the range of 15 to 25 km³, but such estimates are fairly uncertain, owing to glacial erosion. The map area consists exclusively of Quaternary volcanic rocks and derivative surficial deposits. Although most of the area has been modified by glaciation, the volcanoes are young enough that the landforms remain largely constructional. Furthermore, twelve of the 145 eruptive units on the map are postglacial, younger than the deglaciation that was underway by about 17 ka. The most recent eruptions were of rhyolite near South Sister, about 2,000 years ago, and of mafic magma near McKenzie Pass, about 1,500 years ago. As observed by trailblazing volcanologist

    2002-11-01

    Partington et al. [1988] described a three-generation family (MRXS1, MIM *309510, PRTS) with a syndromic form of X-linked mental retardation (XLMR). The clinical features in 10 affected males included mild to moderate MR, dystonic movements of the hands, and dysarthria. After refinement, the PRTS locus was mapped to marker DXS989 (with maximum LOD score of 3.1) with flanking markers DXS365 and DXS28. Since then, no other patients with a similar phenotype have been described. We present a detailed description of the neurological symptoms and the disease history of two brothers with the clinical features of PRTS. Psychomotor development was delayed in both, and neurological features included mild to moderate mental retardation, dysarthria, facial muscle weakness, severe dysdiadochokinesis, slow dystonic movements, and mild spasticity of the hands, without ataxia or spasticity of the legs. The symptoms were nonprogressive and extrapyramidal, and without cerebellar involvement. In general, behavior of the two brothers was friendly and quiet, although the elder brother had periods of depressed mood and outbursts of anger. Karyotypes and subsequent investigation of the subtelomeres as well as DNA analysis of the FMR1 gene, the androgen receptor gene, and the DM locus did not reveal a genetic abnormality. Haplotype analysis showed that the affected brothers share the PRTS region at Xp22.1. Mutation screening of the PDH-E1alpha gene did not reveal a pathogenic mutation.

  20. Evidence of environmental suppression of familial resemblance: height among US Civil War brothers.

    PubMed

    Lauderdale, D S; Rathouz, P J

    1999-01-01

    This study examines, with historical data, whether within family correlations in height varied across environments and whether variability in height was greater in worse environments. To investigate these hypotheses, brothers were identified who were mustered into the Union Army of the US Civil War, using linked records from the 1850 and 1860 censuses and military and medical records. Heights were available for 3898 men aged 18 and older, of whom 595 were further identified as belonging to 288 family sets of two, three or four brothers. Generalized estimating equations were used to concurrently model the mean height, the variance and the correlation between brothers as a function of county population. Heights decreased as county population size increased (p<0.001). The correlation between brothers' heights decreased significantly (p = 0.032) with increasing county population, and the variance increased (p = 0.026). The correlation ranged approximately from 0.63 in the least populous to 0.24 in the most populous counties. The degree of familial resemblance was lower in environments where mean height was lower, and the variability in height was greater, suggesting that the environmental contribution to the variability in height is of greater relative importance in populations reared, on average, in worse environments.

    Although it is well known that the incidence of idiopathic steatorrhea is much higher in relatives of patients with this disease than it is in the general population, there has been little comment on the variability of symptoms in familial cases. Two sisters with this disease are reported. One presented with a relatively acute history of diarrhea, weight loss, fatigue and peripheral edema and was found to have a normal hemoglobin, hypocalcemia and a markedly decreased prothrombin activity. Her elder sister tended to constipation and had a 10-year history of refractory iron-deficiency anemia. The diagnosis was confirmed in both by peroral jejunal biopsy.

    1975-01-01

    A 7-year-old girl was admitted to the hospital for anaemia, secondary to intestinal blood los (melaena). She was found to have 45,X Turner's syndrome. Her identical twin sister also had Turner's syndrome with a 45,X chromosome complement. According to various criteria the probability of monozygosity was 0.9905. Although the incidence of twinning is greater than usual in families of patients with Turner's syndrome, affected cases have only been observed in twin sisters on six occasions. It seems therefore that the 45,X chromosome complement itself is not a factor predisposing to twinning, but that in some families, a factor is at play, which cuases either twinning or the 45,X aneuploidy, or both.

    Lipschütz ulcer (LU) is an uncommon condition that usually affects prepubertal and pubertal girls. It can be misdiagnosed as a sexually transmitted disease or even as a sign of child abuse, causing great anxiety to patients and their families. We present two cases of LU consecutively affecting twin sisters. To our knowledge, this is the first case in two family members, supporting infectious transmission. We propose airborne transmission as the most probable cause in our cases.

    2015-01-01

    Malignant triton tumors (MTTs) are rare and aggressive sarcomas categorized as a subgroup of malignant peripheral nerve sheath tumors (MPNSTs). MTTs arise from Schwann cells of peripheral nerves or existing neurofibromas and have elements of rhabdomyoblastic differentiation. We report the occurrence of MTTs in two sisters. The first patient is a 36-year-old female who presented with left sided chest wall swelling. She also had clinical features consistent with neurofibromatosis type 1 (NF-1). Debulking of the mass showed high-grade malignant peripheral nerve sheath tumor with skeletal muscle differentiation (MTT). The patient was treated with ifosfamide and adriamycin along with radiation. Four years after treatment, she still has no evidence of disease recurrence. Her sister subsequently presented to us at the age of 42 with left sided lateral chest wall pain. Imaging showed a multicompartmental retroperitoneal cystic mass with left psoas involvement. The tumor was resected and, similarly to her sister, it showed high-grade malignant peripheral nerve sheath tumor with rhabdomyoblastic differentiation (MTT). The patient was started on chemotherapy and radiation as described above. PMID:26114002

    2012-01-01

    The tremendous diversity of land plants all descended from a single charophyte green alga that colonized the land somewhere between 430 and 470 million years ago. Six orders of charophyte green algae, in addition to embryophytes, comprise the Streptophyta s.l. Previous studies have focused on reconstructing the phylogeny of organisms tied to this key colonization event, but wildly conflicting results have sparked a contentious debate over which lineage gave rise to land plants. The dominant view has been that 'stoneworts,' or Charales, are the sister lineage, but an alternative hypothesis supports the Zygnematales (often referred to as "pond scum") as the sister lineage. In this paper, we provide a well-supported, 160-nuclear-gene phylogenomic analysis supporting the Zygnematales as the closest living relative to land plants. Our study makes two key contributions to the field: 1) the use of an unbiased method to collect a large set of orthologs from deeply diverging species and 2) the use of these data in determining the sister lineage to land plants. We anticipate this updated phylogeny not only will hugely impact lesson plans in introductory biology courses, but also will provide a solid phylogenetic tree for future green-lineage research, whether it be related to plants or green algae.

    2011-01-01

    In the majority of cases, acromegaly is sporadic. However, it can also occur in a familial setting as a component of MEN-1, MEN-4, Carney complex (CNC) or as the extremely rare syndrome of isolated familial somatotropinoma (IFS), the latter belonging to familial isolated pituitary adenomas (FIPA). The diagnosis of IFS is based on the recognition of acromegaly/gigantism in at least two family members, given that the family is not affected by MEN-1, MEN-4 or CNC. The authors present a case study of two sisters: a 56 year-old patient (case no. 1) and a 61 year-old patient (case no. 2). In both sisters, acromegaly was recognised in the course of pituitary macroadenoma. Neither of the sisters showed features of MEN-1, MEN-4 or Carney complex. The authors suppose that the presented cases are manifestations of IFS. However, this diagnosis has not been confirmed yet because of the poor availability of genetic tests. PMID:22144223

    Starting from the Janus solution and its gauge theory dual, we obtain the dual gauge theory description of the cosmological solution by the procedure of double analytic continuation. The coupling is driven either to zero or to infinity at the big-bang and big-crunch singularities, which are shown to be related by the S-duality symmetry. In the dual Yang-Mills theory description, these are nonsingular as the coupling goes to zero in the N=4 super Yang-Mills theory. The cosmological singularities simply signal the failure of the supergravity description of the full type IIB superstring theory.

  16. Two novel mutations on exon 8 and intron 65 of COL7A1 gene in two Chinese brothers result in recessive dystrophic epidermolysis bullosa.

    2012-01-01

    Dystrophic epidermolysis bullosa is an inherited bullous dermatosis caused by the COL7A1 gene mutation in autosomal dominant or recessive mode. COL7A1 gene encodes type VII collagen - the main component of the anchoring fibrils at the dermal-epidermal junction. Besides the 730 mutations reported, we identified two novel COL7A1 gene mutations in a Chinese family, which caused recessive dystrophic epidermolysis bullosa (RDEB). The diagnosis was established histopathologically and ultrastructurally. After genomic DNA extraction from the peripheral blood sample of all subjects (5 pedigree members and 136 unrelated control individuals), COL7A1 gene screening was performed by polymerase chain reaction amplification and direct DNA sequencing of the whole coding exons and flanking intronic regions. Genetic analysis of the COL7A1 gene in affected individuals revealed compound heterozygotes with identical novel mutations. The maternal mutation is a 2-bp deletion at exon 8 (c.1006_1007delCA), leading to a subsequent reading frame-shift and producing a premature termination codon located 48 amino acids downstream in exon 9 (p.Q336EfsX48), consequently resulting in the truncation of 2561 amino acids downstream. This was only present in two affected brothers, but not in the other unaffected family members. The paternal mutation is a 1-bp deletion occurring at the first base of intron 65 (c.IVS5568+1delG) that deductively changes the strongly conserved GT dinucleotide at the 5' donor splice site, results in subsequent reading-through into intron 65, and creates a stop codon immediately following the amino acids encoded by exon 65 (GTAA→TAA). This is predicted to produce a truncated protein lacking of 1089 C-terminal amino acids downstream. The latter mutation was found in all family members except one of the two unaffected sisters. Both mutations were observed concurrently only in the two affected brothers. Neither mutation was discovered in 136 unrelated Chinese control

    The idea that the purely phenomenological knowledge that we can extract by analyzing large amounts of data can be useful in healthcare seems to contradict the desire of VPH researchers to build detailed mechanistic models for individual patients. But in practice no model is ever entirely phenomenological or entirely mechanistic. We propose in this position paper that big data analytics can be successfully combined with VPH technologies to produce robust and effective in silico medicine solutions. In order to do this, big data technologies must be further developed to cope with some specific requirements that emerge from this application. Such requirements are: working with sensitive data; analytics of complex and heterogeneous data spaces, including nontextual information; distributed data management under security and performance constraints; specialized analytics to integrate bioinformatics and systems biology information with clinical observations at tissue, organ and organisms scales; and specialized analytics to define the "physiological envelope" during the daily life of each patient. These domain-specific requirements suggest a need for targeted funding, in which big data technologies for in silico medicine becomes the research priority. PMID:26218867

    The amount of data at the global level has grown exponentially. Along with this phenomena, we have a need for a new unit of measure like exabyte, zettabyte, and yottabyte as the last unit measures the amount of data. The growth of data gives a situation where the classic systems for the collection, storage, processing, and visualization of data losing the battle with a large amount, speed, and variety of data that is generated continuously. Many of data that is created by the Internet of Things, IoT (cameras, satellites, cars, GPS navigation, etc.). It is our challenge to come up with new technologies and tools for the management and exploitation of these large amounts of data. Big Data is a hot topic in recent years in IT circles. However, Big Data is recognized in the business world, and increasingly in the public administration. This paper proposes an ontology of big data analytics and examines how to enhance business intelligence through big data analytics as a service by presenting a big data analytics services-oriented architecture. This paper also discusses the interrelationship between business intelligence and big data analytics. The proposed approach in this paper might facilitate the research and development of business analytics, big data analytics, and business intelligence as well as intelligent agents.

    A sister noncovalent bond to halogen bond, termed chalcogen bond, is defined in this article. By selecting the complexes H(2)CS...Cl(-), F(2)CS...Cl(-), OCS...Cl(-), and SCS...Cl(-) as models, the bond-length change, interaction energy, topological property of the electron charge density and its Laplacian, and the charge transfer of the chalcogen bond have been investigated in detail theoretically. It was found that the similar misshaped electron clouds of the chalcogen atom and the halogen atom result in the similar properties of the chalcogen bond and the halogen bond. Experimental results are in good agreement with the theoretical predictions.

    This study analyzes the activities of religious sister nurses as they confronted racism in the American South from 1940 to 1972. Selma was chosen as a case study because, in the 1960s, events in that southern town marked a turning point in the civil rights movement in the United States. This is a story about the workings of gender, race, religion, and nursing. The sisters’ work demonstrates how an analysis of race in nursing history is incomplete without an understanding of the roles that a number of Catholic religious women took in reaching out to African Americans in the Deep South.

    2006-03-01

    At the start of the 1930s, theoretician Paul Ehrenfest spent much of his time traveling through America and Europe while engaged in a steady stream of lectures. This traveling phase coincided with a frantic and intense period of negative self-examination, financial difficulty, and various other personal concerns that would ultimately lead to his 1933 suicide. Throughout these final years, he kept up a steady correspondence with his brother Hugo, a physician based in Saint Louis. Ten years older than Paul, Hugo freely doled out frank psychological advice about subjects ranging from the proper treatment of children to the dangers of self-pity. Through a look at some of the letters exchanged between the two brothers, this talk will examine the role Hugo played during the dark final years of Paul Ehrenfest's life.

    NASA Astrophysics Data System (ADS)

    Ling, Eric

    The big bang theory is a model of the universe which makes the striking prediction that the universe began a finite amount of time in the past at the so called "Big Bang singularity." We explore the physical and mathematical justification of this surprising result. After laying down the framework of the universe as a spacetime manifold, we combine physical observations with global symmetrical assumptions to deduce the FRW cosmological models which predict a big bang singularity. Next we prove a couple theorems due to Stephen Hawking which show that the big bang singularity exists even if one removes the global symmetrical assumptions. Lastly, we investigate the conditions one needs to impose on a spacetime if one wishes to avoid a singularity. The ideas and concepts used here to study spacetimes are similar to those used to study Riemannian manifolds, therefore we compare and contrast the two geometries throughout.

    There is increasing evidence that younger sisters of childbearing teenagers are at increased risk for adolescent childbearing. We critically review this research and discuss three plausible theoretical explanations (social modeling, shared parenting influences, and shared societal risk) why the younger sisters of childbearing adolescents would themselves be at risk for teenage pregnancy. Considerations for preventive interventions aimed at the younger sisters of pregnant teenagers and directions for future research are discussed. PMID:1577959

  1. Fluid Flow Patterns in a Submarine Volcano: Simulating the Hydrothermal Evolution of Brothers Volcano

    Brothers volcano is part of the southern Kermadec intra-oceanic arc located northeast of New Zealand, and is one of the world’s best-studied active submarine volcanoes. It provides insight into the complex subseafloor hydrology of a submarine arc volcano with evidence for different stages in its magmatic-hydrothermal evolution [1]. The volcanic edifice comprises an elongated caldera surrounding an asymmetrically centered post-collapse cone. While hydrothermal venting at the NW caldera wall is focused and dates back to at least 1,200 years, hydrothermal discharge at the cone summit is diffuse and considered to be significantly younger. Recent studies of regional seismicity and local harmonic tremor at Brothers volcano imply the existence of a hydrothermal fluid reservoir underneath the area of the present cone [2]. Using a combined finite element - finite volume method, we have computed multi-phase mass and heat transport with a process simulation scheme based on realistic fluid properties. We have used correlations that describe phase stability relations in the binary NaCl-H2O system up to 1000°C [3]. Our earlier results of generic fluid flow simulations showed that water depth and seafloor topography, together with crustal permeability and the relative contributions of seawater and magmatic fluids, are first-order physical parameters controlling the fluid flow patterns and the style of hydrothermal venting. In our more recent simulations, we use available data from Brothers volcano, including detailed bathymetry, physical and chemical measurements from different vent sites and information on the size and location of the subseafloor magma chamber(s). The implementation of two distinct magmatic stages (i.e., pre-cone vs. post-cone) shows that the topography of the volcanic edifice, in combination with the location and size of an underlying magma chamber, play an important role in the style and evolution of the hydrothermal system.

    Following DNA replication, sister chromatids must stay connected for the remainder of the cell cycle in order to ensure accurate segregation in the subsequent cell division. This important function involves an evolutionarily conserved protein complex known as cohesin; any loss of cohesin causes premature sister chromatid separation in mitosis. Here, we examined the role of cohesin in sister chromatid cohesion prior to mitosis, using fluorescence in situ hybridization (FISH) to assay the alignment of sister chromatids in interphase Drosophila cells. Surprisingly, we found that sister chromatid cohesion can be maintained in G2 with little to no cohesin. This capacity to maintain cohesion is widespread in Drosophila, unlike in other systems where a reduced dependence on cohesin for sister chromatid segregation has been observed only at specific chromosomal regions, such as the rDNA locus in budding yeast. Additionally, we show that condensin II antagonizes the alignment of sister chromatids in interphase, supporting a model wherein cohesin and condensin II oppose each other's functions in the alignment of sister chromatids. Finally, because the maternal and paternal homologs are paired in the somatic cells of Drosophila, and because condensin II has been shown to antagonize this pairing, we consider the possibility that condensin II-regulated mechanisms for aligning homologous chromosomes may also contribute to sister chromatid cohesion.

    This study proposes methods to improve the convergence of the novel optimization method, Big Bang-Big Crunch (BB-BC). Uniform population method has been used to generate uniformly distributed random points in the Big Bang phase. Chaos has been utilized to rapidly shrink those points to a single representative point via a center of mass in the Big Crunch phase. The proposed algorithm has been named as Uniform Big Bang-Chaotic Big Crunch (UBB-CBC). The performance of the UBB-CBC optimization algorithm demonstrates superiority over the BB-BC optimization for the benchmark functions.

    Three sisters in a same family (MIAH FAMILY) are of 'Bombay' phenotype. These being the first known female examples of 'Bombay' blood group have been detected in Bangladesh. As predicted by current theory their red cells are Le(a+b-) and their saliva do not contain any of the antigens A, B and H except Lea substance. Family studies showed that individuals with 'Bombay' or Oh phenotype may have A or B gene which are not expressed. This very particular type of blood is one of the rarest in any other parts of world except in India. Due to the presence of anti-H antibody in the plasma of Oh phenotype, when considering such patients for transfusion only blood of identical Bombay type can be safely transfused.

  7. Telomere sister chromatid exchange in telomerase deficient murine cells

    SciTech Connect

    Wang, Yisong; Giannone, Richard J; Liu, Yie

    2005-01-01

    We have recently demonstrated that several types of genomic rearrangements (i.e., telomere sister chromatid exchange (T-SCE), genomic-SCE, or end-to-end fusions) were more often detected in long-term cultured murine telomerase deficient embryonic stem (ES) cells than in freshly prepared murine splenocytes, even through they possessed similar frequencies of critically short telomeres. The high rate of genomic rearrangements in telomerase deficient ES cells, when compared to murine splenocytes, may reflect the cultured cells' gained ability to protect chromosome ends with eroded telomeres allowing them to escape 'end crisis'. However, the possibility that ES cells were more permissive to genomic rearrangements than other cell types or that differences in the microenvironment or genetic background of the animals might consequentially determine the rate of T-SCEs or other genomic rearrangements at critically short telomeres could not be ruled out.

    Mercury (Hg) is a toxic agent that evaporates in room temperature and its inhalation may cause poisoning. Due to the nonspecific symptoms, diagnosis is difficult in special circumstances with no initial history of Hg exposure. We report two such cases of Hg poisoning. The patients were two sisters, presenting with pain in extremities, itchy rashes, sweating, salivation, weakness, and mood changes. They have used a compound that contains mercury, for treatment of pedicullosis three months before admission. This compound was purchased from a herbal shop and was applied locally on the scalps for 2 days. Their urinary mercury concentrations were 50 and 70 mg/L. They were successfully treated by D-penicillamine and gabapentin. In a patient with any kind of bone and joint pain, skin rash erythema and peripheral neuropathy, mercury poisoning should be considered as a differential diagnosis. PMID:26109979

The Center's help-line received 4029 crisis calls in 1994-97. Most clients are seeking information about medical services or legal aid. Others call about employment, HIV/AIDS, alcoholism, and drug abuse. Services are available without regard to age, sex, occupation, or sexual orientation. Program funding has come entirely from Western foundations and organizations. Although Russia has not passed a law on domestic violence, the post-Communism government is reluctantly starting to acknowledge that rape and domestic violence are serious social problems. The Center runs an educational program for law enforcement officers to increase their sensitivity and create an environment of safety for women who report sexual violence. PMID:12294414

    Levin, Peter J

    2011-06-01

    American hospitals were started by religious, ethnic and community groups to serve local health care needs. Immigration into the eastern cities and the constant movement west of the frontier required the creation of educational and service facilities to serve these populations and localities. In the nineteenth century, Catholic sisters went all across the country establishing schools and hospitals. They were motivated to care for the sick, establish charitable institutions and spread their religious beliefs. Their impact on the development of the American health system was enormous. They also supported the importance of nursing for the provision of scientifically based medical care and created schools of nursing. Their historical record as founders, builders, financiers and managers of hospitals is unmatched by any other group between 1850 and 1950. And, this was accomplished at a time when women played no similar leadership and institutional ownership role elsewhere in society. PMID:21452027

    We report on two sisters, 17 and 12 years of age, with clinical features suggesting narcolepsy with cataplexy (NC): daytime sleepiness, spontaneous and emotionally triggered sudden falls to the ground, and overweight/obesity. MSLT showed borderline sleep latency, with 1 and 0 sleep onset REM periods. HLA typing disclosed the DQB1*0602 allele. Video-polygraphy of the spells ruled out NC diagnosis by demonstrating their easy elicitation by suggestion, with wake EEG, electromyographic persistence of muscle tone, and stable presence of tendon reflexes (i.e., pseudo-cataplexy), together with normal cerebrospinal hypocretin-1 levels. Our cases emphasize the need of a clear depiction of cataplexy pattern at the different ages, the usefulness of examining ictal neurophysiology, and collecting all available disease markers in ambiguous cases.

    The increasing availability and growth rate of biomedical information, also known as 'big data', provides an opportunity for future personalized medicine programs that will significantly improve patient care. Recent advances in information technology (IT) applied to biomedicine are changing the landscape of privacy and personal information, with patients getting more control of their health information. Conceivably, big data analytics is already impacting health decisions and patient care; however, specific challenges need to be addressed to integrate current discoveries into medical practice. In this article, I will discuss the major breakthroughs achieved in combining omics and clinical health data in terms of their application to personalized medicine. I will also review the challenges associated with using big data in biomedicine and translational science.

  13. Bayesian big bang

    Daum, Fred; Huang, Jim

    2011-09-01

    We show that the flow of particles corresponding to Bayes' rule has a number of striking similarities with the big bang, including cosmic inflation and cosmic acceleration. We derive a PDE for this flow using a log-homotopy from the prior probability density to the posteriori probability density. We solve this PDE using the gradient of the solution to Poisson's equation, which is computed using an exact Green's function and the standard Monte Carlo approximation of integrals. The resulting flow is analogous to Coulomb's law in electromagnetics. We have used no physics per se to derive this flow, but rather we have only used Bayes' rule and the definition of normalized probability and a loghomotopy parameter that could be interpreted as time. The details of this big bang resemble very recent theories much more closely than the so-called new inflation models, which postulate enormous inflation immediately after the big bang.

    Einstein's equation E = mc2 is often said to mean that energy can be converted into matter. More accurately, energy can be converted to matter and antimatter. During the first moments of the Big Bang, the universe was smaller, hotter and energy was everywhere. As the universe expanded and cooled, the energy converted into matter and antimatter. According to our best understanding, these two substances should have been created in equal quantities. However when we look out into the cosmos we see only matter and no antimatter. The absence of antimatter is one of the Big Mysteries of modern physics. In this video, Fermilab's Dr. Don Lincoln explains the problem, although doesn't answer it. The answer, as in all Big Mysteries, is still unknown and one of the leading research topics of contemporary science.

    Einstein's equation E = mc2 is often said to mean that energy can be converted into matter. More accurately, energy can be converted to matter and antimatter. During the first moments of the Big Bang, the universe was smaller, hotter and energy was everywhere. As the universe expanded and cooled, the energy converted into matter and antimatter. According to our best understanding, these two substances should have been created in equal quantities. However when we look out into the cosmos we see only matter and no antimatter. The absence of antimatter is one of the Big Mysteries of modern physics. In this video, Fermilab's Dr. Don Lincoln explains the problem, although doesn't answer it. The answer, as in all Big Mysteries, is still unknown and one of the leading research topics of contemporary science.

    Presented is a case report of a violent sexual assault where the DNA profile obtained from an item of evidence was compared to a suspect's profile. The profiles did not match, but the sharing of such a large number of alleles raised the suspicion that perhaps the real perpetrator was a blood relative of the suspect. The investigators requested a sample from the suspect's brother, and a match was defined. In an era of technological breakthroughs in the field of forensic DNA analysis, the importance of the scientist's attention to the evidence presented in each case is stressed.

    Interest in hoarding behavior has intensified, as it works its way through DSM-V deliberations and treatment models. Meanwhile, both documentarians and fiction writers have embraced accounts of individuals with disposophobia and romanticized versions of the Collyer brothers, the Hermits of Harlem. In this article, I examine the range of media and professional attention given to hoarders and their problems and then focus on a potential role for forensic mental health professionals. The psycholegal problems of hoarders include health and zoning code violations that evolve into criminal charges, civil commitment, questions of animal cruelty, landlord-tenant disputes, divorce and custody evaluations, testamentary capacity, and child-neglect charges.

  2. Replication-Dependent Sister Chromatid Recombination in Rad1 Mutants of Saccharomyces Cerevisiae

    Homolog recombination and unequal sister chromatid recombination were monitored in rad1-1/rad1-1 diploid yeast cells deficient for excision repair, and in control cells, RAD1/rad1-1, after exposure to UV irradiation. In a rad1-1/rad1-1 diploid, UV irradiation stimulated much more sister chromatid recombination relative to homolog recombination when cells were irradiated in the G(1) or the G(2) phases of the cell cycle than was observed in RAD1/rad1-1 cells. Since sister chromatids are not present during G(1), this result suggested that unexcised lesions can stimulate sister chromatid recombination events during or subsequent to DNA replication. The results of mating rescue experiments suggest that unexcised UV dimers do not stimulate sister chromatid recombination during the G(2) phase, but only when they are present during DNA replication. We propose that there are two types of sister chromatid recombination in yeast. In the first type, unexcised UV dimers and other bulky lesions induce sister chromatid recombination during DNA replication as a mechanism to bypass lesions obstructing the passage of DNA polymerase, and this type is analogous to the type of sister chromatid exchange commonly observed cytologically in mammalian cells. In the second type, strand scissions created by X-irradiation or the excision of damaged bases create recombinogenic sites that result in sister chromatid recombination directly in G(2). Further support for the existence of two types of sister chromatid recombination is the fact that events induced in rad1-1/rad1-1 were due almost entirely to gene conversion, whereas those in RAD1/rad1-1 cells were due to a mixture of gene conversion and reciprocal recombination.

    Data Science is more than the creation, manipulation, and transformation of data. It is more than Big Data. The business world seems to have a hold on the term 'data science' and, for now, they define what it means. But business is very different than science. In this talk, I address how large datasets, Big Data, and data science are conceptually different in business and science worlds. I focus on the types of questions each realm asks, the data needed, and the consequences of findings. Gone are the days of datasets being created or collected to serve only one purpose or project. The trick with data reuse is to become familiar enough with a dataset to be able to combine it with other data and extract accurate results. As a Data Curator for the Advanced Cooperative Arctic Data and Information Service (ACADIS), my specialty is communication. Our team enables Arctic sciences by ensuring datasets are well documented and can be understood by reusers. Previously, I served as a data community liaison for the North American Regional Climate Change Assessment Program (NARCCAP). Again, my specialty was communicating complex instructions and ideas to a broad audience of data users. Before entering the science world, I was an entrepreneur. I have a bachelor's degree in economics and a master's degree in environmental social science. I am currently pursuing a Ph.D. in Geography. Because my background has embraced both the business and science worlds, I would like to share my perspectives on data, data reuse, data documentation, and the presentation or communication of findings. My experiences show that each can inform and support the other.

  13. Familial appearance of congenital penile curvature – case history of two brothers

    2013-01-01

    The true prevalence of congenital penile curvature (CPC) is difficult to determine. Some study reports suggests that this problem may occur in as many as 10% of the male population [1]. However, a literature search of the Medline database revealed no reference concerning familial appearance of congenital penile curvature. For that reason we would like to present our case series. Two brothers aged 25 and 26 respectively were admitted to the department of urology due to congenital penile curvature. Each patient was assessed by a history, physical examination, auto-photography of the erect penis, and a thorough sexual history. Concomitant anomalies of penile layers were absent in both cases. The Yachia [2] and Essed-Schroeder [3] corporoplasty technique were applied respectively. In follow-up both brothers reported straight erections. A survey of the fetal penis at different stages of development shows some degree of curvature in a considerable number of embryos [4]. Penile curvature may thus be considered almost physiological in embryos between 35 and 45 mm in length. Thus, it has also been proposed that penile curvature is secondary to an arrest in normal penile development [5]. Therefore, some form of congenital local androgen deficiency may be responsible for inherited penile curvature. PMID:24579033

    2016-01-01

    Objective: The purpose of this study is to describe a case series of 4 sisters with discordant clinical phenotypes associated with fragile X–associated tremor/ataxia syndrome (FXTAS) that may be explained by varying CGG repeat sizes and activation ratios (ARs) (the ratio of cells carrying the normal fragile X mental retardation 1 [FMR1] allele on the active X chromosome). Methods: Four sisters with premutation size FMR1 gene repeats underwent detailed clinical characterization. CGG repeat length was determined by PCR, and AR was determined using a newly developed commercial methylation PCR assay and was compared with the results from Southern blot with densitometric image analysis. Results: Sister 1 had the largest CGG expansion (82) and the lowest AR (12%), with the most severe clinical presentation. Sister 2 had a lower CGG expansion (70) and an AR of 10% but had a milder clinical presentation.Sister 3 had a similar CGG expansion (79) but a slightly higher AR of 15% and less neurologic involvement. Sister 4 had a similar CGG expansion size of 80 but had the largest AR (40%) and was the only sister not to be affected by FXTAS or have any neurologic signs on examination. Conclusions: These results suggest that premutation carrier women who have higher ARs may be less likely to show manifestations of FXTAS. If larger studies show similar patterns, AR data could potentially be beneficial to supplement CGG repeat size when counseling premutation carrier women in the clinic. PMID:27066582

  16. Two sisters in the same dress: Heliconius cryptic species

    PubMed Central

    2008-01-01

    Background Sister species divergence and reproductive isolation commonly results from ecological adaptation. In mimetic Heliconius butterflies, shifts in colour pattern contribute to pre- and post-mating reproductive isolation and are commonly correlated with speciation. Closely related mimetic species are therefore not expected, as they should lack several important sources of reproductive isolation. Results Here we present phenotypic, behavioral and genetic evidence for the coexistence of two sympatric 'cryptic' species near Florencia in the eastern Andes of Colombia that share the same orange rayed colour pattern. These represent H. melpomene malleti and a novel taxon in the H. cydno group, here designated as novel race of Heliconius timareta, Heliconius timareta florencia. No-choice mating experiments show that these sympatric forms have strong assortative mating (≈96%) despite great similarity in colour pattern, implying enhanced divergence in pheromonal signals. Conclusion We hypothesize that these species might have resulted from recent convergence in colour pattern, perhaps facilitated by hybrid introgression of wing pattern genes. PMID:19040737

    Molecular phylogenetic studies have not yet reached a consensus on the placement of Ginkgoales, which is represented by the only living species, Ginkgo biloba (common name: ginkgo). At least six discrepant placements of ginkgo have been proposed. This study aimed to use the chloroplast phylogenomic approach to examine possible factors that lead to such disagreeing placements. We found the sequence types used in the analyses as the most critical factor in the conflicting placements of ginkgo. In addition, the placement of ginkgo varied in the trees inferred from nucleotide (NU) sequences, which notably depended on breadth of taxon sampling, tree-building methods, codon positions, positions of Gnetopsida (common name: gnetophytes), and including or excluding gnetophytes in data sets. In contrast, the trees inferred from amino acid (AA) sequences congruently supported the monophyly of a ginkgo and Cycadales (common name: cycads) clade, regardless of which factors were examined. Our site-stripping analysis further revealed that the high substitution saturation of NU sequences mainly derived from the third codon positions and contributed to the variable placements of ginkgo. In summary, the factors we surveyed did not affect results inferred from analyses of AA sequences. Congruent topologies in our AA trees give more confidence in supporting the ginkgo-cycad sister-group hypothesis.

    To test the recently developed method of exposing cells to volatile compounds, phytohemagglutinin-stimulated human peripheral lymphocyte cultures were exposed to gaseous methyl bromide, ethylene oxide, and propylene oxide, as well as diesel exhaust. The cultures were placed in sterile dialysis tubing and inserted into enclosed flasks containing additional culture medium. The test compounds (in gaseous state) were diluted with air and bubbled through the flasks for various lengths of time. The cells were then washed and incubated for a total of 75 h. The harvest was performed according to established procedures, and second-division cells were scored for induction of sister chromatid exchanges (SCEs). The SCE frequency was more than doubled in the cultures treated with ethylene oxide and propylene oxide; methyl bromide also induced SCEs. Cultures treated with diesel exhaust showed an increase in the SCE frequency in cells from two of four donors tested. These results further substantiate the use of this method for detecting the induction of SCEs by airborne genotoxins.

  19. Newly discovered sister lineage sheds light on early ant evolution

    2008-01-01

    Ants are the world's most conspicuous and important eusocial insects and their diversity, abundance, and extreme behavioral specializations make them a model system for several disciplines within the biological sciences. Here, we report the discovery of a new ant that appears to represent the sister lineage to all extant ants (Hymenoptera: Formicidae). The phylogenetic position of this cryptic predator from the soils of the Amazon rainforest was inferred from several nuclear genes, sequenced from a single leg. Martialis heureka (gen. et sp. nov.) also constitutes the sole representative of a new, morphologically distinct subfamily of ants, the Martialinae (subfam. nov.). Our analyses have reduced the likelihood of long-branch attraction artifacts that have troubled previous phylogenetic studies of early-diverging ants and therefore solidify the emerging view that the most basal extant ant lineages are cryptic, hypogaeic foragers. On the basis of morphological and phylogenetic evidence we suggest that these specialized subterranean predators are the sole surviving representatives of a highly divergent lineage that arose near the dawn of ant diversification and have persisted in ecologically stable environments like tropical soils over great spans of time.

    The early evolutionary history of Ornithodira (avian-line archosaurs) has hitherto been documented by incomplete (Lagerpeton) or unusually specialized forms (pterosaurs and Silesaurus). Recently, a variety of Silesaurus-like taxa have been reported from the Triassic period of both Gondwana and Laurasia, but their relationships to each other and to dinosaurs remain a subject of debate. Here we report on a new avian-line archosaur from the early Middle Triassic (Anisian) of Tanzania. Phylogenetic analysis places Asilisaurus kongwe gen. et sp. nov. as an avian-line archosaur and a member of the Silesauridae, which is here considered the sister taxon to Dinosauria. Silesaurids were diverse and had a wide distribution by the Late Triassic, with a novel ornithodiran bauplan including leaf-shaped teeth, a beak-like lower jaw, long, gracile limbs, and a quadrupedal stance. Our analysis suggests that the dentition and diet of silesaurids, ornithischians and sauropodomorphs evolved independently from a plesiomorphic carnivorous form. As the oldest avian-line archosaur, Asilisaurus demonstrates the antiquity of both Ornithodira and the dinosaurian lineage. The initial diversification of Archosauria, previously documented by crocodilian-line archosaurs in the Anisian, can now be shown to include a contemporaneous avian-line radiation. The unparalleled taxonomic diversity of the Manda archosaur assemblage indicates that archosaur diversification was well underway by the Middle Triassic or earlier. PMID:20203608

    Kleckner, Nancy; Fisher, Jay K.; Stouf, Mathieu; White, Martin A.; Bates, David; Witz, Guillaume

    2014-01-01

    Recent studies reveal that the bacterial nucleoid has a defined, self-adherent shape and an underlying longitudinal organization and comprises a viscoelastic matrix. Within this shape, mobility is enhanced by ATP-dependent processes and individual loci can undergo ballistic off-equilibrium movements. In E.coli, two global dynamic nucleoid behaviors emerge pointing to nucleoid-wide accumulation and relief of internal stress. Sister segregation begins with local splitting of individual loci, which is delayed at origin, terminus and specialized interstitial snap regions. Globally, as studied in several systems, segregation is a multi-step process in which internal nucleoid state plays critical roles that involve both compaction and expansion. The origin and terminus regions undergo specialized programs partially driven by complex ATP burning mechanisms such as a ParAB Brownian ratchet and a septum-associated FtsK motor. These recent findings reveal strong, direct parallels among events in different systems and between bacterial nucleoids and mammalian chromosomes with respect to physical properties, internal organization and dynamic behaviors.

    Adult female cercopithecines have long been known to bias their social behaviour towards close maternal kin. However, much less is understood about the behaviour of paternal kin, especially in wild populations. Here, we show that wild adult female baboons bias their affiliative behaviour towards their adult paternal half-sisters in the same manner and to the same extent that they bias their behaviour towards adult maternal half-sisters. Females appear to rely heavily on social familiarity as a means of biasing their behaviour towards paternal half-sisters, but may use phenotype matching as well. PMID:12641905

    Big Bang Circus is an opera I composed in 2001 and which was premiered at the Venice Biennale Contemporary Music Festival in 2002. A chamber group, four singers and a ringmaster stage the story of the Universe confronting and interweaving two threads: how early man imagined it and how scientists described it. Surprisingly enough fancy, myths and scientific explanations often end up using the same images, metaphors and sometimes even words: a strong tension, a drumskin starting to vibrate, a shout…

    Summary Objectives To provide an editorial introduction into the 2014 IMIA Yearbook of Medical Informatics with an overview of the content, the new publishing scheme, and upcoming 25th anniversary. Methods A brief overview of the 2014 special topic, Big Data - Smart Health Strategies, and an outline of the novel publishing model is provided in conjunction with a call for proposals to celebrate the 25th anniversary of the Yearbook. Results ‘Big Data’ has become the latest buzzword in informatics and promise new approaches and interventions that can improve health, well-being, and quality of life. This edition of the Yearbook acknowledges the fact that we just started to explore the opportunities that ‘Big Data’ will bring. However, it will become apparent to the reader that its pervasive nature has invaded all aspects of biomedical informatics – some to a higher degree than others. It was our goal to provide a comprehensive view at the state of ‘Big Data’ today, explore its strengths and weaknesses, as well as its risks, discuss emerging trends, tools, and applications, and stimulate the development of the field through the aggregation of excellent survey papers and working group contributions to the topic. Conclusions For the first time in history will the IMIA Yearbook be published in an open access online format allowing a broader readership especially in resource poor countries. For the first time, thanks to the online format, will the IMIA Yearbook be published twice in the year, with two different tracks of papers. We anticipate that the important role of the IMIA yearbook will further increase with these changes just in time for its 25th anniversary in 2016. PMID:24853037

    The singleton, term gestation, live birth rate per cycle initiated (BESST) endpoint proposed at the beginning of 2004 is a first big step which should be added to by the consideration of multiple pregnancy rates in relation to singleton rates, by recording of fetal reductions and of pregnancies resulting from cryopreserved material. After three or more steps we may have an accurate reporting system which helps patients to distinguish the pros and cons for singleton term delivery. PMID:15479704

    The so-called big data revolution provides substantial opportunities to diabetes management. At least 3 important directions are currently of great interest. First, the integration of different sources of information, from primary and secondary care to administrative information, may allow depicting a novel view of patient’s care processes and of single patient’s behaviors, taking into account the multifaceted nature of chronic care. Second, the availability of novel diabetes technologies, able to gather large amounts of real-time data, requires the implementation of distributed platforms for data analysis and decision support. Finally, the inclusion of geographical and environmental information into such complex IT systems may further increase the capability of interpreting the data gathered and extract new knowledge from them. This article reviews the main concepts and definitions related to big data, it presents some efforts in health care, and discusses the potential role of big data in diabetes care. Finally, as an example, it describes the research efforts carried on in the MOSAIC project, funded by the European Commission. PMID:25910540

    Sex chromosomes have evolved independently in many different taxa, and so have mechanisms to compensate for expression differences on sex chromosomes in males and females. Different clades have evolved vastly different ways to achieve dosage compensation, including hypertranscription of the single X in male Drosophila, downregulation of both X's in XX Caenorhabditis, or inactivation of one X in female mammals. In the flour beetle Tribolium, the X appears hyperexpressed in both sexes, which might represent the first of two steps to evolve dosage compensation along the paths mammals may have taken (i.e., upregulation of X in both sexes, followed by inactivation of one X in females). Here we test for dosage compensation in Strepsiptera, a sister taxon to beetles. We identify sex-linked chromosomes in Xenos vesparum based on genomic analysis of males and females, and show that its sex chromosome consists of two chromosomal arms in Tribolium: The X chromosome that is shared between Tribolium and Strepsiptera, and another chromosome that is autosomal in Tribolium and another distantly related Strepsiptera species, but sex-linked in X. vesparum. We use RNA-seq (RNA sequencing) to show that dosage compensation along the X of X. vesparum is partial and heterogeneous. In particular, genes that are X-linked in both beetles and Strepsiptera appear fully dosage compensated probably through downregulation in both sexes, whereas genes on the more recently added X segment have evolved only partial dosage compensation. In addition, reanalysis of published RNA-seq data suggests that Tribolium has evolved dosage compensation, without hypertranscribing the X in females. Our results demonstrate that patterns of dosage compensation are highly variable across sex-determination systems and even within species.

    When energetic particles irradiate matter, it becomes activated by nuclear reactions. Radioactivation induced cellular effects are not clearly understood, but it could be a part of bystander effects. This investigation is aimed at understanding the biological effects from radioactivation in solution induced by hadron radiation. Water or phosphate buffered saline was activated by being exposed to hadron radiation including protons, carbon- and iron-ions. 1 mL of radioactivated solution was transferred to flasks with Chinese hamster ovary (CHO) cells cultured in 5 mL of complete media. The induction of sister chromatid exchanges (SCE) was used to observe any increase in DNA damage responses. The energy spectrum and the half-lives of the radioactivation were analyzed by NaI scintillation detector in order to identify generated radionuclides. In the radioactivated solution, 511 keV gamma-rays were observed, and their half-lives were approximately 2 min, 10 min, and 20 min. They respectively correspond to the beta+ decay of 15O, 13N, and 11C. The SCE frequencies in CHO cells increased depending on the amount of radioactivation in the solution. These were suppressed with a 2-hour delayed solution transfer or pretreatment with dimethyl sulfoxide (DMSO). Our results suggest that the SCE induction by radioactivated solution was mediated by free radicals produced by the annihilated gamma-rays. Since the SCE induction and DMSO modulation are also reported in radiation-induced bystander effects, our results imply that radioactivation of the solution may have some contribution to the bystander effects from hadron radiation. Further investigations are required to assess if radioactivation effects would attribute an additional level of cancer risk of the hadron radiation therapy itself. PMID:26657140

    In this report, we describe two adult brothers affected by moderate non-specific intellectual disability (ID). They showed minor facial anomalies, not clearly ascribable to any specific syndromic patterns, microcephaly, brachydactyly and broad toes. Both brothers presented seizures. Karyotype, subtelomeric and FMR1 analysis were normal in both cases. We performed array-CGH analysis that revealed no copy-number variations potentially associated with ID. Subsequent exome sequence analysis allowed the identification of the ATRX c.109C>T (p.R37X) mutation in both the affected brothers. Sanger sequencing confirmed the presence of the mutation in the brothers and showed that the mother is a healthy carrier. Mutations in the ATRX gene cause the X-linked alpha thalassemia/mental retardation (ATR-X) syndrome (MIM #301040), a severe clinical condition usually associated with profound ID, facial dysmorphism and alpha thalassemia. However, the syndrome is clinically heterogeneous and some mutations, including the c.109C>T, are associated with a broad phenotypic spectrum, with patients displaying a less severe phenotype with only mild-moderate ID. In the case presented here, exome sequencing provided an effective strategy to achieve the molecular diagnosis of ATR-X syndrome, which otherwise would have been difficult to consider due to the mild non-specific phenotype and the absence of a family history with typical severe cases.

    Research on anxiety treatment with African American women reveals a need to develop interventions that address factors relevant to their lives. Such factors include feelings of isolation, multiple roles undertaken by Black women, and faith. A recurrent theme across treatment studies is the importance of having support from other Black women. Sister circles are support groups that build upon existing friendships, fictive kin networks, and the sense of community found among African Americans females. Sister circles appear to offer many of the components Black women desire in an anxiety intervention. In this article, we explore sister circles as an intervention for anxious African American women. Culturally-infused aspects from our sister circle work with middle-class African American women are presented. Further research is needed. PMID:22081747

    Carbon-monoxide (630080) and carbon-dioxide (124389) concentrations were measured at Salomon Brothers, Incorporated (SIC-6711), New York, New York, in September and October, 1984. The evaluation was requested by the firm's medical department because of complaints of headache and eye, nose, and sinus irritation among employees who worked on the 40th floor, trading center. Ventilation surveys were also performed. After additional ventilation equipment was installed, a second survey found that the outdoor air supplied exceeded the ASHRAE recommendations. Following installation of the supplemental ventilation equipment, the employees complaints abated. The author concludes that in the preliminary survey, a potential health hazard existed due to an inadequate supply of fresh air. Installation of additional ventilation equipment removed the potential hazard.

  6. [The brothers of Jumiege--the peripheral nervous system in early French mythology].

    2002-03-20

    This article reviews the process of discovery of the nervous system from Pythagoras (570-500 BC) to Galen (130-201 AD). After Galen, no anatomical studies were performed before the renaissance. According to a legend, probably produced for political reasons, two brothers, sons of the French king Clovis II, revolted against their father and were sentenced to loose their physical powers by having the nerves of their arms and legs cut. They were then set adrift on the river Seine, stranding at the Jumiège monastery. The earliest written version of this legend stems from the fourteenth century; it was probably a part of the local French mythology. This indicates that the existence of the peripheral nervous system, and therefore also in part the knowledge contained in the early anatomical works, quite early may have been more or less known outside academic circles.

    The Mathis Brothers Landfill (MBL) is on the National Priorities List. MBL is a 20-acre site and is located on the east side of Marble Top Road, one-half mile south of State Highway 136 near Kensington (Walker), Georgia. MBL was licensed by the State to accept nonhazardous waste. The landfill is uncapped and rusted, leaking drums presently exist on-site. No removal operations have occurred. On-site contaminants of concern include lead, various residues from herbicide manufacturing and latex waste from carpet manufacturing. Based on the available information, the site is considered to be of potential public health concern because of the risk to human health caused by the possibility of exposure to hazardous substances.

  8. Observations of Local Seismicity and Harmonic Tremor Using an Ocean Bottom Hydrophone Array at Brothers Volcano, South Kermadec Arc.

    The submarine Brothers volcano is an important link in the volcanic chain of the southern Kermadec Arc system in the Southwest Pacific Ocean north of New Zealand. The 3-3.5 km wide caldera has a center depth of 1850m and steep surrounding walls of 300-450m. Active hydrothermal venting distinguished Brothers as a point of focus for the New Zealand American Submarine Ring of Fire (NZASRoF) expeditions in 2004 and 2005. Due to its remote location, moderate to small magnitude seismicity around the Brothers area is largely unknown. In late September 2004, four ocean bottom hydrophones (OBHs) were deployed on the caldera floor. In April 2005, three of the four instruments were recovered intact. These three OBHs continuously recorded, for seven months, the low frequency (0-110Hz) acoustic field around Brothers volcano, in particular seismic P- and S-waves propagating through the crust and acoustic T-waves in the water column . Preliminary analysis reveals seismicity rates on the order of 106 earthquakes per month. In addition to seismic arrivals, low frequency harmonic tremor is frequently and independently observed on each of the OBH instruments, often occurring subsequent to the larger seismic events. Qualitative comparisons of these signals with tremor observed from the Volcano Islands south of Japan (Dziak and Fox, 2002) show them to be nearly equivalent in frequency structure, suggesting the origin of the tremor observed at Brothers may also be attributed to resonance of a magma-gas mixture in a large chamber or conduit near the water/ seafloor boundary.

    Understanding how complex traits, such as epithelia, nervous systems, muscles, or guts, originated depends on a well-supported hypothesis about the phylogenetic relationships among major animal lineages. Traditionally, sponges (Porifera) have been interpreted as the sister group to the remaining animals, a hypothesis consistent with the conventional view that the last common animal ancestor was relatively simple and more complex body plans arose later in evolution. However, this premise has recently been challenged by analyses of the genomes of comb jellies (Ctenophora), which, instead, found ctenophores as the sister group to the remaining animals (the "Ctenophora-sister" hypothesis). Because ctenophores are morphologically complex predators with true epithelia, nervous systems, muscles, and guts, this scenario implies these traits were either present in the last common ancestor of all animals and were lost secondarily in sponges and placozoans (Trichoplax) or, alternatively, evolved convergently in comb jellies. Here, we analyze representative datasets from recent studies supporting Ctenophora-sister, including genome-scale alignments of concatenated protein sequences, as well as a genomic gene content dataset. We found no support for Ctenophora-sister and conclude it is an artifact resulting from inadequate methodology, especially the use of simplistic evolutionary models and inappropriate choice of species to root the metazoan tree. Our results reinforce a traditional scenario for the evolution of complexity in animals, and indicate that inferences about the evolution of Metazoa based on the Ctenophora-sister hypothesis are not supported by the currently available data.

    The 22q13.3 deletion, or Phelan-McDermid syndrome, is characterized by global intellectual disability, generalized hypotonia, severely delayed or absent speech associated with features of autism spectrum disorder, and minor dysmorphisms. Its behavioral phenotype comprises sleep disturbances, communication deficits, and motor perseverations. Data on psychological dysfunctions are so far not available. Previous studies have suggested that the loss of one copy of the gene SH3 and multiple ankyrin repeat domains 3 (SHANK3) is related to the neurobehavioral phenotype. Additional genes proximal to SHANK3 are also likely to play a role in the phenotype of patients with larger deletions. The present paper describes two adult brothers with an identical 2.15 Mb 22qter (22q13.32q13.33) deletion, of whom the youngest was referred for evaluation of recurrent mood changes. In both patients, magnetic resonance imaging of the brain showed hypoplasia of the vermis cerebelli. Extensive clinical examinations led to a final diagnosis of atypical bipolar disorder, of which symptoms fully remitted during treatment with a mood stabilizer. In the older brother, a similar psychopathological picture appeared to be present, although less severe and with a later onset. It is concluded that the behavioral phenotype of the 22q13.3 deletion syndrome comprises absent or delayed speech and perseverations with associated autistic-like features, whereas its psychopathological phenotype comprises an atypical bipolar disorder. The latter may have implications for the treatment regime of the syndrome-related behavioral disturbances. PMID:22570549

    How Big is Earth celebrates the Year of Light. Using only the sunlight striking the Earth and a wooden dowel, students meet each other and then measure the circumference of the earth. Eratosthenes did it over 2,000 years ago. In Cosmos, Carl Sagan shared the process by which Eratosthenes measured the angle of the shadow cast at local noon when sunlight strikes a stick positioned perpendicular to the ground. By comparing his measurement to another made a distance away, Eratosthenes was able to calculate the circumference of the earth. How Big is Earth provides an online learning environment where students do science the same way Eratosthenes did. A notable project in which this was done was The Eratosthenes Project, conducted in 2005 as part of the World Year of Physics; in fact, we will be drawing on the teacher's guide developed by that project.How Big Is Earth? expands on the Eratosthenes project by providing an online learning environment provided by the iCollaboratory, www.icollaboratory.org, where teachers and students from Sweden, China, Nepal, Russia, Morocco, and the United States collaborate, share data, and reflect on their learning of science and astronomy. They are sharing their information and discussing their ideas/brainstorming the solutions in a discussion forum. There is an ongoing database of student measurements and another database to collect data on both teacher and student learning from surveys, discussions, and self-reflection done online.We will share our research about the kinds of learning that takes place only in global collaborations.The entrance address for the iCollaboratory is http://www.icollaboratory.org.

  13. Silicic Eruptions of the Past 50 kyr at the Three Sisters Volcanic Cluster

    2003-12-01

    The Three Sisters volcanic cluster in the central Oregon Cascades consists of mafic to intermediate stratovolcanoes surrounded by mafic and silicic flows and domes. The bulk of South and Middle Sister are late Pleistocene while North Sister is middle Pleistocene (Schmidt and Grunder, 2003 GSA abs.). Thick rhyolite and dacite lava flows and domes are rich in potassium, and young glaciation exposes holocrystalline groundmass textures ideal for argon geochronology. Several of these silicic flows bracket stratovolcano growth, and precise geochronology illuminates a rich basalt to rhyolite history in the cluster over the past 50 kyr. Careful step-heating 40Ar/39Ar experiments yield excellent plateau ages with radiogenic yields often above 5% on rocks as young as 20 ka. Most samples have well-determined isochrons with atmospheric (40/36 = 295.5) intercepts, although several have intercepts as low as 286. South Sister is a composite cone with an andesite/dacite base (Hodge Crest) and a young andesite summit sequence. The basal flow of the 300m-thick, youngest conformable stack of andesite lavas at the summit is 27+/-3 ka. Unconformably underlying portions date back to at least 50 ka based on ages of overlapping silicic flows. The base of Middle Sister is andesite overlain by ˜300m of olivine basalt. Some Middle Sister andesites and all basalts overlie a distinctive dacite agglutinate (20+/-2 ka) in the South/Middle Sister saddle. All Middle Sister lavas underlie a thick dacite flow (14+/-3 ka) that vented at 8500 ft (2600m) on its S flank. Dacite lava flows erupted from the Middle/North Sister saddle at 27+/-2 and 18+/-2 ka. Additionally, several >100m-thick rhyolite and dacite lavas vented low on the flanks of the cluster. Obsidian Cliff rhyolite (37.8+/-1.8 ka) and Lane Plateau dacite (21.4+/-1.9 ka) erupted W of Middle Sister, the Dew Lake dacite (32.3+/-1.8 ka) located near the locus of the INSAR anomaly W of South Sister flowed around a 148+/-4 ka (knob 6482) basalt

    In some fields, Big Data has been instrumental in analyzing, predicting, and influencing human behavior. However, Big Data approaches have so far been less central in speech-language pathology. This article introduces the concept of Big Data and provides examples of Big Data initiatives pertaining to adult neurorehabilitation. It also discusses the potential theoretical and clinical contributions that Big Data can make. The article also recognizes some impediments in building and using Big Data for scientific and clinical inquiry.

  20. Identifying possible sister groups of Cryptocercidae+Isoptera: a combined molecular and morphological phylogeny of Dictyoptera.

    Termites (Isoptera) offer an alternative model for the development of eusociality which is not dependent on a high degree of relatedness as found between sisters in hymenopterans (bees, wasps, ants). Recent phylogenetic studies have established that termites belong within the cockroaches as sister to the subsocial Cryptocercidae. Cryptocercidae shares several important traits with termites, thus we need to understand the phylogenetic position of Cryptocercidae+Isoptera to determine how these traits evolved. However, placement of Cryptocercidae+Isoptera is still uncertain. We used both molecular (12S, 16S, COII, 18S, 28S, H3) and morphological characters to reconstruct the phylogeny of Dictyoptera. We included all previously suggested sister groups of Cryptocercidae+Isoptera as well as taxa which might represent additional major cockroach lineages. We used Bayes factors to test different sister groups for Cryptocercidae+Isoptera and assessed character support for the consensus tree based on morphological characters and COII amino acid data. We used the molecular data and fossil calibration to estimate divergence times. We found the most likely sister groups of Cryptocercidae+Isoptera to be Tryonicidae, Anaplecta or Tryonicidae+Anaplecta. Anaplecta has never previously been suggested as sister group or even close to Cryptocercidae+Isoptera, but was formerly placed in Blaberoidea as sister to the remaining taxa. Topological tests firmly supported our new placement of Anaplecta. We discuss the morphological characters (e.g. retractable genitalic hook) that have contributed to the previous placement of Anaplecta in Blaberoidea as well as the factors that might have contributed to a parallel development of genitalic features in Anaplecta and Blaberoidea. Cryptocercidae+Isoptera is placed in a clade with Tryonicidae, Anaplecta and possibly Lamproblattidae. Based on this, we suggest that wood-feeding, and the resultant need to conserve nitrogen, may have been an important

  1. Digital Data for Volcano Hazards of the Three Sisters Region, Oregon

    Three Sisters is one of three active volcanic centers that lie close to rapidly growing communities and resort areas in Central Oregon. The major composite volcanoes of this area are clustered near the center of the region and include South Sister, Middle Sister, and Broken Top. Additionally, hundreds of mafic volcanoes are scattered throughout the Three Sisters area. These range from small cinder cones to large shield volcanoes like North Sister and Belknap Crater. Hazardous events include landslides from the steep flanks of large volcanoes and floods, which need not be triggered by eruptions, as well as eruption-triggered events such as fallout of tephra (volcanic ash) and lava flows. A proximal hazard zone roughly 20 kilometers (12 miles) in diameter surrounding the Three Sisters and Broken Top could be affected within minutes of the onset of an eruption or large landslide. Distal hazard zones that follow river valleys downstream from the Three Sisters and Broken Top could be inundated by lahars (rapid flows of water-laden rock and mud) generated either by melting of snow and ice during eruptions or by large landslides. Slow-moving lava flows could issue from new mafic volcanoes almost anywhere within the region. Fallout of tephra from eruption clouds can affect areas hundreds of kilometers (miles) downwind, so eruptions at volcanoes elsewhere in the Cascade Range also contribute to volcano hazards in Central Oregon. Scientists at the Cascades Volcano Observatory created a geographic information system (GIS) data set which depicts proximal and distal lahar hazard zones as well as a regional lava flow hazard zone for Three Sisters (USGS Open-File Report 99-437, Scott and others, 1999). The various distal lahar zones were constructed from LaharZ software using 20, 100, and 500 million cubic meter input flow volumes. Additionally, scientists used the depositional history of past events in the Three Sisters Region as well as experience and judgment derived from the

    Background Homologous chromosomes separate in meiosis I and sister chromatids separate in meiosis II, generating haploid gametes. To address the question why sister chromatids do not separate in meiosis I, we explored the roles of Shogoshin1 (Sgo1) in chromosome separation during oocyte meiosis. Methodology/Principal Findings Sgo1 function was evaluated by exogenous overexpression to enhance its roles and RNAi to suppress its roles during two meioses of mouse oocytes. Immunocytochemistry and chromosome spread were used to evaluate phenotypes. The exogenous Sgo1 overexpression kept homologous chromosomes and sister chromatids not to separate in meiosis I and meiosis II, respectively, while the Sgo1 RNAi promoted premature separation of sister chromatids. Conclusions Our results reveal that prevention of premature separation of sister chromatids in meiosis I requires the retention of centromeric Sgo1, while normal separation of sister chromatids in meiosis II requires loss of centromeric Sgo1.

    We report on the possibility of using dark matter particle's mass and its interaction cross section as a smoking gun signal of the existence of a big bounce at the early stage in the evolution of our currently observed universe. A model independent study of dark matter production in the pre-bounce contraction and the post-bounce expansion epochs of the bounce universe reveals a new venue for achieving the observed relic abundance of our present universe, in which a significantly smaller amount of dark matter with a smaller cross section—as compared to the prediction of standard cosmology—is produced and the information about the bounce universe evolution is preserved by the out-of-thermal-equilibrium process. Once the value of dark matter mass and interaction cross section are obtained by direct detection in laboratories, this alternative route becomes a signature prediction of the bounce universe scenario.

    Big Data brings unprecedented power to address scientific, economic and societal issues, but also amplifies the possibility of certain pitfalls. These include using purely data-driven approaches that disregard understanding the phenomenon under study, aiming at a dynamically moving target, ignoring critical data collection issues, summarizing or preprocessing the data inadequately and mistaking noise for signal. We review some success stories and illustrate how statistical principles can help obtain more reliable information from data. We also touch upon current challenges that require active methodological research, such as strategies for efficient computation, integration of heterogeneous data, extending the underlying theory to increasingly complex questions and, perhaps most importantly, training a new generation of scientists to develop and deploy these strategies.

  5. Sisters unbound is required for meiotic centromeric cohesion in Drosophila melanogaster.

    Regular meiotic chromosome segregation requires sister centromeres to mono-orient (orient to the same pole) during the first meiotic division (meiosis I) when homologous chromosomes segregate, and to bi-orient (orient to opposite poles) during the second meiotic division (meiosis II) when sister chromatids segregate. Both orientation patterns require cohesion between sister centromeres, which is established during meiotic DNA replication and persists until anaphase of meiosis II. Meiotic cohesion is mediated by a conserved four-protein complex called cohesin that includes two structural maintenance of chromosomes (SMC) subunits (SMC1 and SMC3) and two non-SMC subunits. In Drosophila melanogaster, however, the meiotic cohesion apparatus has not been fully characterized and the non-SMC subunits have not been identified. We have identified a novel Drosophila gene called sisters unbound (sunn), which is required for stable sister chromatid cohesion throughout meiosis. sunn mutations disrupt centromere cohesion during prophase I and cause high frequencies of non-disjunction (NDJ) at both meiotic divisions in both sexes. SUNN co-localizes at centromeres with the cohesion proteins SMC1 and SOLO in both sexes and is necessary for the recruitment of both proteins to centromeres. Although SUNN lacks sequence homology to cohesins, bioinformatic analysis indicates that SUNN may be a structural homolog of the non-SMC cohesin subunit stromalin (SA), suggesting that SUNN may serve as a meiosis-specific cohesin subunit. In conclusion, our data show that SUNN is an essential meiosis-specific Drosophila cohesion protein. PMID:25194162

  6. Cell biology of cancer: BRCA1 and sister chromatid pairing reactions?

    PubMed

    2008-02-15

    A significant portion of familial breast/ovarian cancer patients harbors a mutation in Breast Cancer Associated gene 1 (BRCA1). Cells deficient for BRCA1 exhibit chromosome aberrations such as whole chromosome duplications, translocations, inter-sister gaps and gene mis-regulation. Here, new evidence is reviewed that defects in sister chromatid cohesion may contribute directly to cancer cell phenotypes-especially those of BRCA1 mutant cells. Linking cohesion to BRCA1-dependent tumorigenesis are reports that BRCA1-associated components (DNA helicase, RFC, PCNA and genome surveillance factors) are required for efficient sister chromatid cohesion. Other cohesion factors (WAPL, EFO2/ESCO2 and hSecurin) are tightly correlated with various cell-type specific carcinogenesis, in support of a generalized model for cohesion in cancer. Recent findings further reveal that a reciprocal relationship exists in that DNA damage induces new Ctf7/Eco1-dependent sister chromatid pairing reactions that, in turn, are required for efficient DNA repair. Future research into sister chromatid pairing mechanisms are likely to provide critical new insights into the underlying causes of cancer.

  7. Sister cohesion and structural axis components mediate homolog bias of meiotic recombination

    2010-01-01

    SUMMARY Meiotic recombination occurs between one chromatid of each maternal and paternal homolog (homolog bias) versus between sister chromatids (sister bias). Physical DNA analysis reveals that meiotic cohesin/axis component Rec8 promotes sister bias, likely via its cohesion activity. Two meiosis-specific axis components, Red1/Mek1kinase, counteract this effect. With this precondition satisfied, other molecules directly specify homolog bias per se. Rec8 also acts positively to maintain homolog bias during crossover recombination. These observations point to sequential release of double-strand break ends from association with their sister. Red1 and Rec8 are found to play distinct roles for sister cohesion, DSB formation and recombination progression kinetics. Also, the two components are enriched in spatially distinct domains of axial structure that develop prior to DSB formation. We propose that Red1 and Rec8 domains provide functionally complementary environments whereby inputs evolved from DSB repair and late-stage chromosome morphogenesis are integrated to give the complete meiotic chromosomal program.

    This analysis of the preferences of how sisters and charge nurses are managed is the result of a two centre descriptive study using theoretical models of professionalism, developing preferences and exercising situational leadership. It was conducted to determine if the management structure preferred by sisters and charge nurses, in a general acute hospital setting, supported the professionalism of nursing. The outcomes were intended to help develop a strategic plan for the future of nursing and the management of nurses. The research instruments were a self-completed questionnaire (19 were returned, a response rate of 31.1%) and four semi-structured interviews. The findings disclosed some dissatisfaction with the present management arrangements. The sisters and charge nurses felt that their priorities for practice and professional issues were better supported by clinically involved, ward-based senior nurses than by unit-based senior nurses with a general management function. However, sisters' and charge nurses' discussions with ward-based senior nurses were apparently less effective than discussions in peer groups which led to influential collegial autonomy. This preferred management style can be supported by the use of situational leadership theory which would enhance collegial autonomy and professional satisfaction. Recognition of the sisters and charge nurses preferences and adjustment of their management would therefore enable them to participate effectively in organizational decision-making.

    Understanding how complex traits, such as epithelia, nervous systems, muscles, or guts, originated depends on a well-supported hypothesis about the phylogenetic relationships among major animal lineages. Traditionally, sponges (Porifera) have been interpreted as the sister group to the remaining animals, a hypothesis consistent with the conventional view that the last common animal ancestor was relatively simple and more complex body plans arose later in evolution. However, this premise has recently been challenged by analyses of the genomes of comb jellies (Ctenophora), which, instead, found ctenophores as the sister group to the remaining animals (the “Ctenophora-sister” hypothesis). Because ctenophores are morphologically complex predators with true epithelia, nervous systems, muscles, and guts, this scenario implies these traits were either present in the last common ancestor of all animals and were lost secondarily in sponges and placozoans (Trichoplax) or, alternatively, evolved convergently in comb jellies. Here, we analyze representative datasets from recent studies supporting Ctenophora-sister, including genome-scale alignments of concatenated protein sequences, as well as a genomic gene content dataset. We found no support for Ctenophora-sister and conclude it is an artifact resulting from inadequate methodology, especially the use of simplistic evolutionary models and inappropriate choice of species to root the metazoan tree. Our results reinforce a traditional scenario for the evolution of complexity in animals, and indicate that inferences about the evolution of Metazoa based on the Ctenophora-sister hypothesis are not supported by the currently available data.

  11. Cohesin ensures bipolar attachment of microtubules to sister centromeres and resists their precocious separation.

    The multisubunit protein complex cohesin is required to establish cohesion between sister chromatids during S phase and to maintain it during G2 and M phases. Cohesin is essential for mitosis, and even partial defects cause very high rates of chromosome loss. In budding yeast, cohesin associates with specific sites which are distributed along the entire length of a chromosome but are more dense in the vicinity of the centromere. Real-time imaging of individual centromeres tagged with green fluorescent protein suggests that cohesin bound to centromeres is important for bipolar attachment to microtubules. This cohesin is, however, incapable of resisting the consequent force, which leads to sister centromere splitting and chromosome stretching. Meanwhile, cohesin bound to sequences flanking the centromeres prevents sister chromatids from completely unzipping and is required to pull back together sister centromeres that have already split. Cohesin therefore has a central role in generating a dynamic tension between microtubules and sister chromatid cohesion at centromeres, which lasts until chromosome segregation is finally promoted by separin-dependent cleavage of the cohesin subunit Scc1p.

Previous tests in birds showed that individuals can be correctly assigned to species in ~94% of the cases and suggested a threshold of 10× mean intraspecific difference to detect potential new species. However, these tests were criticized because they were based on a single maternally inherited gene rather than multiple nuclear genes, did not compare phylogenetically identified <span class="hlt">sister</span> species, and thus likely overestimated the efficacy of DNA barcodes in identifying species. Results To test the efficacy of DNA barcodes we compared ~650 bp of COI in 60 <span class="hlt">sister</span>-species pairs identified in multigene phylogenies from 10 orders of birds. In all pairs, individuals of each species were monophyletic in a neighbor-joining (NJ) tree, and each species possessed fixed mutational differences distinguishing them from their <span class="hlt">sister</span> species. Consequently, individuals were correctly assigned to species using a statistical coalescent framework. A coalescent test of taxonomic distinctiveness based on chance occurrence of reciprocal monophyly in two lineages was verified in known <span class="hlt">sister</span> species, and used to identify recently separated lineages that represent putative species. This approach avoids the use of a universal distance cutoff which is invalidated by variation in times to common ancestry of <span class="hlt">sister</span> species and in rates of evolution. Conclusion Closely related <span class="hlt">sister</span> species of birds can be identified reliably by barcodes of fixed diagnostic substitutions in COI sequences, verifying coalescent-based statistical tests of reciprocal monophyly for taxonomic distinctiveness. Contrary to recent criticisms, a single DNA barcode is a rapid way to discover monophyletic lineages within a metapopulation that might represent undiscovered cryptic species, as envisaged in the unified species concept.

Males are predicted to evolve adaptations against spermicide, but few antispermicidal mechanisms have been definitively identified. One such adaptation may be the enigmatic infertile sperm morphs or "parasperm" produced by many species, which have been hypothesized to protect their fertile <span class="hlt">brother</span> "eusperm" from spermicide [2, 3]. Here, we show that female Drosophila pseudoobscura reproductive tracts are spermicidal and that the survival of eusperm after exposure to the female tract is highest when males produce many parasperm. This study clarifies the adaptive significance of infertile sperm castes, which has remained elusive in Drosophila and other taxa despite much recent interest [2-8]. We suggest that spermicide and male countermeasures against it are more common than is appreciated currently and discuss how spermicide could drive the evolution of several key male traits, including sperm size and number.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.ncbi.nlm.nih.gov/pubmed/24670344','PUBMED'); return false;" href="https://www.ncbi.nlm.nih.gov/pubmed/24670344"><span id="translatedtitle">Vitamin D intoxication in two <span class="hlt">brothers</span>: be careful with dietary supplements.</span></a></p> <p><a target="_blank" href="https://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Conti, Giovanni; Chirico, Valeria; Lacquaniti, Antonio; Silipigni, Lorena; Fede, Claudia; Vitale, Agata; Fede, Carmelo</p> <p>2014-07-01</p> <p>Vitamin D (VitD) intoxication, a well-known cause of hypercalcaemia in children, has renal, cardiac and neurological consequences.

Transgenic lines that constitutively overexpress BOA exhibit physiological and developmental changes, including delayed flowering time and increased vegetative growth under standard growing conditions. Arabidopsis circadian clock protein CIRCADIAN CLOCK ASSOCIATED1 (CCA1) binds to the evening element of the BOA promoter and negatively regulates its expression. Furthermore, the period of BOA rhythm was shortened in cca1-11, lhy-21 (for LATE ELONGATED HYPOCOTYL), and cca1-11 lhy-21 genetic backgrounds. BOA binds to the promoter of CCA1 through newly identified promoter binding sites and activates the transcription of CCA1 in vivo and in vitro. In transgenic Arabidopsis lines that overexpress BOA, the period length of CCA1 rhythm was increased and the amplitude was enhanced. Rhythmic expression of other clock genes, including LHY, GIGANTEA (GI), and TIMING OF CAB EXPRESSION1 (TOC1), was altered in transgenic lines that overexpress BOA. Rhythmic expression of BOA was also affected in mutant lines of toc1-1, gi-3, and gi-4.

We measure climate at increasing spatial resolution by means of satellites and look farther back in time at increasing temporal resolution by means of natural archives and proxy data. We use powerful supercomputers to run climate models. The model output of the calculations made for the IPCC's Fifth Assessment Report amounts to ~650 TB. The 'scientific evolution' of grid computing has started, and the 'scientific revolution' of quantum computing is being prepared. This will increase computing power, and data amount, by several orders of magnitude in the future. However, more data does not automatically mean more knowledge. We need statisticians, who are at the core of transforming data into knowledge. Statisticians notably also explore the limits of our knowledge (uncertainties, that is, confidence intervals and P-values). Mudelsee (2014 Climate Time Series Analysis: Classical Statistical and Bootstrap Methods. Second edition. Springer, Cham, xxxii + 454 pp.) coined the term 'optimal estimation'. Consider the hyperspace of climate estimation. It has many, but not infinite, dimensions. It consists of the three subspaces Monte Carlo design, method and measure. The Monte Carlo design describes the data generating process. The method subspace describes the estimation and confidence interval construction. The measure subspace describes how to detect the optimal estimation method for the Monte Carlo experiment. The envisaged large increase in computing power may bring the following idea of optimal climate estimation into existence. Given a data sample, some prior information (e.g. measurement standard errors) and a set of questions (parameters to be estimated), the first task is simple: perform an initial estimation on basis of existing knowledge and experience with such types of estimation problems.

It becomes toxic when accumulated in the body. It causes vomiting, fatigue and renal failure. Methods The heparinized blood samples from 40 healthy men were studied for the impact of borax toxicity on immune cell proliferation (lymphocyte proliferation) and <span class="hlt">sister</span> chromatid exchange in human chromosomes. The MTT assay and <span class="hlt">Sister</span> Chromatid Exchange (SCE) technic were used in this experiment with the borax concentrations of 0.1, 0.15, 0.2, 0.3 and 0.6 mg/ml. Results It showed that the immune cell proliferation (lymphocyte proliferation) was decreased when the concentrations of borax increased. The borax concentration of 0.6 mg/ml had the most effectiveness to the lymphocyte proliferation and had the highest cytotoxicity index (CI). The borax concentrations of 0.15, 0.2, 0.3 and 0.6 mg/ml significantly induced <span class="hlt">sister</span> chromatid exchange in human chromosomes (P < 0.05). Conclusion Borax had effects on immune cell proliferation (lymphocyte proliferation) and induced <span class="hlt">sister</span> chromatid exchange in human chromosomes.

To date, phylogenetic support for either ctenophores or sponges as <span class="hlt">sister</span> to other animals has been limited and inconsistent among studies. Lack of agreement among phylogenomic analyses using different data and methods obscures how complex traits, such as epithelia, neurons, and muscles evolved. A consensus view of animal evolution will not be accepted until datasets and methods converge on a single hypothesis of early metazoan relationships and putative sources of systematic error (e.g., long-branch attraction, compositional bias, poor model choice) are assessed. Here, we investigate possible causes of systematic error by expanding taxon sampling with eight novel transcriptomes, strictly enforcing orthology inference criteria, and progressively examining potential causes of systematic error while using both maximum-likelihood with robust data partitioning and Bayesian inference with a site-heterogeneous model. We identified ribosomal protein genes as possessing a conflicting signal compared with other genes, which caused some past studies to infer ctenophores and cnidarians as <span class="hlt">sister</span>. Importantly, biases resulting from elevated compositional heterogeneity or elevated substitution rates are ruled out. Placement of ctenophores as <span class="hlt">sister</span> to all other animals, and sponge monophyly, are strongly supported under multiple analyses, herein.

Interestingly, non-kinetochore microtubules have been observed between <span class="hlt">sister</span> kinetochores, but their function is unknown. Here we show by laser-cutting of a k-fibre in HeLa and PtK1 cells that a bundle of non-kinetochore microtubules, which we term ‘bridging fibre', bridges <span class="hlt">sister</span> k-fibres and balances the interkinetochore tension. We found PRC1 and EB3 in the bridging fibre, suggesting that it consists of antiparallel dynamic microtubules. By using a theoretical model that includes a bridging fibre, we show that the forces at the pole and at the kinetochore depend on the bridging fibre thickness. Moreover, our theory and experiments show larger relaxation of the interkinetochore distance for cuts closer to kinetochores. We conclude that the bridging fibre, by linking <span class="hlt">sister</span> k-fibres, withstands the tension between <span class="hlt">sister</span> kinetochores and enables the spindle to obtain a curved shape.

In a 54-year-old woman, <span class="hlt">Sister</span> Mary Joseph's nodule was unexpectedly detected during umbilical hernia repair.

How tension is read to signal the bioriented state remains unclear. Shugoshins form a pericentromeric platform that integrates multiple functions to ensure proper chromosome biorientation. Here we show that budding yeast shugoshin Sgo1 dissociates from the pericentromere reversibly in response to tension. The antagonistic activities of the kinetochore-associated Bub1 kinase and the Sgo1-bound phosphatase protein phosphatase 2A (PP2A)-Rts1 underlie a tension-dependent circuitry that enables Sgo1 removal upon <span class="hlt">sister</span> kinetochore biorientation. Sgo1 dissociation from the pericentromere triggers dissociation of condensin and Aurora B from the centromere, thereby stabilizing the bioriented state. Conversely, forcing <span class="hlt">sister</span> kinetochores to be under tension during meiosis I leads to premature Sgo1 removal and precocious loss of pericentromeric cohesion. Overall, we show that the pivotal role of shugoshin is to build a platform at the pericentromere that attracts activities that respond to the absence of tension between <span class="hlt">sister</span> kinetochores.

To explore the function of ORC in more detail, a screen for genetic interactions was undertaken using large-scale synthetic lethal analysis. Combination of orc2-1 and orc5-1 alleles with the complete set of haploid deletion mutants revealed synthetic lethal/sick phenotypes with genes involved in DNA replication, chromatin structure, checkpoints, DNA repair and recombination, and other genes that were unexpected on the basis of previous studies of ORC. Many of these genetic interactions are shared with other genes that are involved in initiation of DNA replication. Strong synthetic interactions were demonstrated with null mutations in genes that contribute to <span class="hlt">sister</span> chromatid cohesion. A genetic interaction between orc5-1 and the cohesin mutant scc1-73 suggested that ORC function contributes to <span class="hlt">sister</span> chromatid cohesion.

The <span class="hlt">Sisters</span> of Charity of St. Joseph was founded in 1809 by Saint Elizabeth Ann Bailey Seton (first native-born North American canonized in 1975) in Emmitsburg, Maryland. Seton's <span class="hlt">Sisters</span> of Charity was the first community for religious women to be established in the United States and was later incorporated with the French Daughters of Charity of St. Vincent de Paul in 1850. A call to work in New Orleans' Charity Hospital in the 1830s meant a significant achievement for the <span class="hlt">Sisters</span> of Charity, since it was the second oldest continuously operating public hospitals in the United States until 2005, bearing the same name over the decades. In 1834, <span class="hlt">Sister</span> Regina Smith and other <span class="hlt">sisters</span> were officially called to Charity Hospital, in order to supersede the existing "nurses, attendants, and servants," and take a complete charge of the internal management of Charity Hospital. The existing scholarship on the history of hospitals and Catholic nursing has not integrated the concrete stories of the <span class="hlt">Sisters</span> of Charity into the broader histories of institutionalized medicine, gender, and religion. Along with a variety of primary sources, this study primarily relies on the Charity Hospital History Folder stored at the Daughters of Charity West Center Province Archives. Located in the "Queen city of the South," Charity Hospital was the center of the southern medical profession and the world's fair of people and diseases. Charity Hospital provided the <span class="hlt">sisters</span> with a unique situation that religion and medicine became intertwined. The <span class="hlt">Sisters</span>, as nurses, constructed a new atmosphere of caring for patients and even their families inside and outside the hospital, and built their own separate space within the hospital walls. As hospital managers, the <span class="hlt">Sisters</span> of Charity were put in complete charge of the hospital, which was never seen in other hospitals.

As such it represents a landmark decision. The case arose from the illegal detention, torture and extrajudicial execution of two minors, Emilio and Rafael Gomez Paquiyauri, at the hands of Peruvian Police in 1991, under the Fujimori Administration at a time when the internal war in Peru was at its peak. Unlike most cases coming to the jurisdiction of the Inter-American Court, the case had been subject to domestic criminal investigations that had led to the convictions of two low ranking policemen. Yet a more subtle pattern of impunity lied at the root of the case. Torture had been denied by the State, and the prosecutions of low ranking policemen had intended to cover up the responsibility of those who ordered a policy of torture and executions (including the existence of secret codes for the torture and elimination of suspects of "terrorism") during the years of the internal armed conflict in Peru. The joint work of legal and medical expertise in the litigation of the case permitted the establishment of the facts and the law, obtaining an award of 740,500 dollars for the victims and a number of measures of reparation including guarantees of non-repetition and satisfaction, such as the naming of a school after the victims.

The 25 <span class="hlt">sister</span> rods are all high burnup and cover the range of modern domestic cladding alloys. The 25 <span class="hlt">sister</span> rods were shipped to Oak Ridge National Laboratory (ORNL) in early 2016 for detailed non-destructive and destructive examination. Examinations are intended to provide baseline data on the initial physical state of the cladding and fuel prior to the loading, drying, and long-term dry storage process. Further examinations are focused on determining the effects of temperatures encountered during and following drying. Similar tests will be performed on rods taken from the project assemblies at the end of their long-term storage in a TN-32 dry storage cask (the cask rods ) to identify any significant changes in the fuel rods that may have occurred during the dry storage period. Additionally, some of the <span class="hlt">sister</span> rods will be used for separate effects testing to expand the applicability of the project data to the fleet, and to address some of the data-related gaps associated with extended storage and subsequent transportation of high burnup fuel. A draft test plan is being developed that describes the experimental work to be conducted on the <span class="hlt">sister</span> rods.

Individuals from a fragile X positive family previously studied using linked markers were analyzed for CGG repeat size by PCR amplification and Southern blot. Two individuals previously given an 8% risk for being transmitting males were found to have 47 CGG repeats which could be considered normal, and thus be consistent with the linked marker results. However, analysis of one daughter and grandchild has shown that this allele is meiotically unstable, with allele size increasing from 47 to 48 to 49 from father to daughter to grandaughter. In addition, CGG repeat analysis of a <span class="hlt">sister</span> of these two individuals has indicated that their mother, who is an obligate premutation carrier, must have had a normal allele of 29, thus suggesting the 47 allele represents a premutation in these males. We conclude that FMR1 CGG allele sizes of as small as 47 can be meiotically unstable with presumably an increased risk of expansion to a full mutation in future generations. This example illustrates the importance of analyzing additional family members for the presence of instability in cases where CGG allele sizes in the 40`s are found.</p> </li> </ol> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_19");'>19</a></li> <li><a href="#" onclick='return showDiv("page_20");'>20</a></li> <li class="active"><span>21</span></li> <li><a href="#" onclick='return showDiv("page_22");'>22</a></li> <li><a href="#" onclick='return showDiv("page_23");'>23</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div><!-- col-sm-12 --> </div><!-- row --> </div><!-- page_21 --> <div id="page_22" class="hiddenDiv"> <div class="row"> <div class="col-sm-12"> <div class="pull-right"> <ul class="pagination"> <li><a href="#" onclick='return showDiv("page_1");'>«</a></li> <li><a href="#" onclick='return showDiv("page_20");'>20</a></li> <li><a href="#" onclick='return showDiv("page_21");'>21</a></li> <li class="active"><span>22</span></li> <li><a href="#" onclick='return showDiv("page_23");'>23</a></li> <li><a href="#" onclick='return showDiv("page_24");'>24</a></li> <li><a href="#" onclick='return showDiv("page_25");'>»</a></li> </ul> </div> </div> </div> <div class="row"> <div class="col-sm-12"> <ol class="result-class" start="421"> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.ncbi.nlm.nih.gov/pubmed/26614539','PUBMED'); return false;" href="https://www.ncbi.nlm.nih.gov/pubmed/26614539"><span id="translatedtitle">[<span class="hlt">Big</span> Data- challenges and risks].</span></a></p> <p><a target="_blank" href="https://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Krauß, Manuela; Tóth, Tamás; Hanika, Heinrich; Kozlovszky, Miklós; Dinya, Elek</p> <p>2015-12-01</p> <p>The term "<span class="hlt">Big</span> Data" is commonly used to describe the growing mass of information being created recently.

Previous studies indicated that short telomeres are associated with increased risk for human bladder, head and neck, lung, and renal cell cancer. We investigated the association between white blood cell telomere length and breast cancer risk among 268 family sets (287 breast cancer cases and 350 <span class="hlt">sister</span> controls). Telomere length was assessed by quantitative PCR. The mean telomere length was shorter in cases (mean, 0.70; range, 0.03-1.95) than in unaffected control <span class="hlt">sisters</span> (mean, 0.74; range, 0.03-2.29), but no significant difference was observed (P = 0.11). When subjects were categorized according to the median telomere length in controls (0.70), affected <span class="hlt">sisters</span> had shorter telomeres compared with unaffected <span class="hlt">sisters</span> after adjusting for age at blood donation and smoking status [odds ratio (OR), 1.3; 95% confidence interval (95% CI), 0.9-1.8], but the association was not statistically significant. The association by quartile of telomere length (Q4 shortest versus Q1 longest) also supported an increase in risk from shorter telomere length, although the association was not statistically significant (OR, 1.6; 95% CI, 0.9-2.7). This association was more pronounced among premenopausal women (OR, 2.1; 95% CI, 0.8-5.5) than postmenopausal women (OR, 1.3; 95% CI, 0.5-3.6 for Q4 versus Q1). If these associations are replicated in larger studies, they provide modest epidemiologic evidence that shortened telomere length may be associated with breast cancer risk.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=2670183','PMC'); return false;" href="https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=2670183"><span id="translatedtitle">Characterization of the components of the putative mammalian <span class="hlt">sister</span> chromatid cohesion complex</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Darwiche, N.; Freeman, L.A.; Strunnikov, A.</p> <p>2009-01-01</p> <p>Establishing and maintaining proper <span class="hlt">sister</span> chromatid cohesion throughout the cell cycle are essential for maintaining genome integrity. To understand how <span class="hlt">sister</span> chromatid cohesion occurs in mammals, we have cloned and characterized mouse orthologs of proteins known to be involved in <span class="hlt">sister</span> chromatid cohesion in other organisms. The cDNAs for the mouse orthologs of SMC1S.c. and SMC3S.c., mSMCB and mSMCD respectively, were cloned and the corresponding transcripts and proteins were characterized. mSMCB and mSMCD are transcribed at similar levels in adult mouse tissues except in testis, which has an excess of mSMCD transcripts. The mSMCB and mSMCD proteins, as well as the PW29 protein, a mouse homolog of Mcd1pS.c./Rad21S.p., form a complex similar to cohesin in X. laevis. mSMCB, mSMCD and PW29 protein levels show no significant cell-cycle dependence. The bulk of the mSMCB, mSMCD and PW29 proteins undergo redistribution from the chromosome vicinity to the cytoplasm during prometaphase and back to the chromatin in telophase. This pattern of intracellular localization suggests a complex role for this group of SMC proteins in chromosome dynamics. The PW29 protein and PCNA, which have both been implicated in <span class="hlt">sister</span> chromatid cohesion, do not colocalize, indicating that these proteins may not function in the same cohesion pathway. Overexpression of a PW29-GFP fusion protein in mouse fibroblasts leads to inhibition of proliferation, implicating this protein and its complex with SMC proteins in the control of mitotic cycle progression.

An unusual microbial community was detected with only 1% and 40% of the bacterial phylotypes exhibiting >92% small subunit (SSU) rRNA gene sequence similarity with cultivated and noncultivated microbes, respectively. Of the 29 bacterial representative phylotypes, over one third of the SSU rRNA gene sequences retrieved belonged to uncultivated candidate divisions including OP1, OP3, OP5, OP8, OD1, and OP11. All archaeal phylotypes belonged to the phylum Euryarchaeota in the uncultivated groups deep hydrothermal vent euryarchaeotal (DHVE) I and II or to the phylum Korarchaeota. Like the bacterial clone library, only a small proportion of archaeal SSU rRNA gene sequences (˜2% and 20%) displayed >92% sequence identity with any archaeal isolates or noncultivated microbes, respectively. Although the bacterial phylotypes detected were phylogenetically most similar to microbial communities detected in methane, hydrocarbon, and carbon dioxide-based hydrothermal and seep environments, no phylotypes directly associated with anaerobic methane oxidation and mcrA activity could be detected. The geochemical composition of the vent fluids at the <span class="hlt">Brothers</span>-lower cone sample site is unusual and we suggest that it may play a prominent role in the species selection of this microbial community.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/1167036','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/1167036"><span id="translatedtitle"><span class="hlt">Big</span> Explosives Experimental Facility - BEEF</span></a></p> <p><a target="_blank" href="http://www.osti.gov/scitech">SciTech Connect</a></p> <p></p> <p>2014-10-31</p> <p>The <span class="hlt">Big</span> Explosives Experimental Facility or BEEF is a ten acre fenced high explosive testing facility that provides data to support stockpile stewardship and other national security programs.

Banding analyses indicated a nonrandom distribution of chromosome breaks in the lymphocytes and marrow cells of the Bloom's syndrome patient.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.ncbi.nlm.nih.gov/pubmed/24162982','PUBMED'); return false;" href="https://www.ncbi.nlm.nih.gov/pubmed/24162982"><span id="translatedtitle">A historical overview of bromo-substituted DNA and <span class="hlt">sister</span> chromatid differentiation.</span></a></p> <p><a target="_blank" href="https://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Mezzanotte, Roberto; Nieddu, Mariella</p> <p>2014-01-01</p> <p>The thymidine analogue 5-bromo-2'-deoxyuridine (BrdU) has been widely used to make <span class="hlt">sister</span> chromatid differentiation (SCD) evident in metaphase chromosomes of cells grown for two cycles in BrdU and, thus, containing varying amounts of the thymidine analogue. A direct consequence was the possibility of making <span class="hlt">sister</span> chromatid exchange (SCE) evident without using autoradiographic procedures. The latter phenomenon was first discovered in 1953, and its frequency is considered a reliable marker of pathological cell situations, as well as an indicator of mutagenic compounds. Several experimental procedures were found which produced SCD, such as the use of fluorochromes like 33258 Hoechst or acridine orange, whose observation under fluorescence microscopy was directly recorded by photos or stained with Giemsa to make chromosome preparations permanent. Other treatments followed by Giemsa staining required the use of saline hot solutions, acid solutions, nuclease attack and specific monoclonal antibodies. Basically two molecular mechanisms were invoked to explain the different affinity of Giemsa stain for differential BrdU-substituted chromatid DNA. The first implied debromination of chromatid DNA, whose occurrence would be greater in chromatids containing an amount of BrdU greater than that present in <span class="hlt">sister</span> chromatids. The second mechanism, although not denying the importance of DNA debromination, postulated that chromatin structural organization, in terms of DNA-protein and/or protein-protein DNA interaction, is responsible for SCD production.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4766734','PMC'); return false;" href="https://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pmcentrez&artid=4766734"><span id="translatedtitle">An Smc3 Acetylation Cycle Is Essential for Establishment of <span class="hlt">Sister</span> Chromatid Cohesion</span></a></p> <p><a target="_blank" href="http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pmc">PubMed Central</a></p> <p>Beckouët, Frederic; Hu, Bin; Roig, Maurici B.; Sutani, Takashi; Komata, Makiko; Uluocak, Pelin; Katis, Vittorio L.; Shirahige, Katsuhiko; Nasmyth, Kim</p> <p>2015-01-01</p> <p>SUMMARY <span class="hlt">Sister</span> chromatid cohesion is thought to involve entrapment of <span class="hlt">sister</span> DNAs by a tripartite ring composed of the cohesin subunits Smc1, Smc3, and Scc1. Establishment of cohesion during S phase depends on acetylation of Smc3’s nucleotide-binding domain (NBD) by the Eco1 acetyl transferase. It is destroyed at the onset of anaphase due to Scc1 cleavage by separase. In yeast, Smc3 acetylation is reversed at anaphase by the Hos1 deacetylase as a consequence of Scc1 cleavage. Smc3 molecules that remain acetylated after mitosis due to Hos1 inactivation cannot generate cohesion during the subsequent S phase, implying that cohesion establishment depends on de novo acetylation during DNA replication. By inducing Smc3 deacetylation in postreplicative cells due to Hos1 overexpression, we provide evidence that Smc3 acetylation contributes to the maintenance of <span class="hlt">sister</span> chromatid cohesion. A cycle of Smc3 NBD acetylation is therefore an essential aspect of the chromosome cycle in eukaryotic cells.

Aneuploid eggs result from chromosome segregation errors when an egg develops from a progenitor cell, called an oocyte. The mechanisms that lead to an increase in aneuploidy with advanced maternal age are largely unclear. Here, we show that many <span class="hlt">sister</span> kinetochores in human oocytes are separated and do not behave as a single functional unit during the first meiotic division. Having separated <span class="hlt">sister</span> kinetochores allowed bivalents to rotate by 90 degrees on the spindle and increased the risk of merotelic kinetochore-microtubule attachments. Advanced maternal age led to an increase in <span class="hlt">sister</span> kinetochore separation, rotated bivalents and merotelic attachments. Chromosome arm cohesion was weakened, and the fraction of bivalents that precociously dissociated into univalents was increased. Together, our data reveal multiple age-related changes in chromosome architecture that could explain why oocyte aneuploidy increases with advanced maternal age.

Methods A systematic search was performed using two major bibliographic databases for relevant journal papers. The references obtained were reviewed in a two-stage process, starting with a blinded review performed by the two section editors, and followed by a peer review process operated by external reviewers recognized as experts in the field. Results The complete review process selected four best papers, illustrating various aspects of the special theme, among them: (a) using large volumes of unstructured data and, specifically, clinical notes from Electronic Health Records (EHRs) for pharmacovigilance; (b) knowledge discovery via querying large volumes of complex (both structured and unstructured) biological data using <span class="hlt">big</span> data technologies and relevant tools; (c) methodologies for applying cloud computing and <span class="hlt">big</span> data technologies in the field of genomics, and (d) system architectures enabling high-performance access to and processing of large datasets extracted from EHRs. Conclusions The potential of <span class="hlt">big</span> data in biomedicine has been pinpointed in various viewpoint papers and editorials. The review of current scientific literature illustrated a variety of interesting methods and applications in the field, but still the promises exceed the current outcomes. As we are getting closer towards a solid foundation with respect to common understanding of relevant concepts and technical aspects, and the use of standardized technologies and tools, we can anticipate to reach the potential that <span class="hlt">big</span> data offer for personalized medicine and smart health strategies in the near future.

C.; Asmerom, Y.</p> <p>2011-12-01</p> <p>The central Oregon Cascades are unique due to an abundance of mafic post-glacial volcanism found nowhere else within the arc, as well as an exceptional volume of rhyolite, which is typically restricted to rear-arc centers in the rest of the Cascades. Within central Oregon, South <span class="hlt">Sister</span> and Newberry, a large stratovolcano and major rear-arc center respectively, have both erupted bimodal basalt-rhyolite suites during the Holocene, with compositional gaps at ˜ 56-72 wt.% SiO2. The mafic lavas are generally accepted to be mantle-derived melts, variously modified by AFC processes. However, the origin of the felsic rocks is more contentious. Numerous studies have focused on South <span class="hlt">Sister</span>, and have invoked a variety of processes to explain the bimodal suite there, including assimilation-fractional crystallization from a mafic parent, and partial to complete melting of a variety of crustal lithologies ranging from mafic amphibolite to granite. The Holocene obsidian flows of Newberry volcano have received less attention, although they have also been interpreted as discrete, small volume melts of a granitic source. In order to place further constraints on the processes involved in their genesis, we have obtained 238U-230Th-226Ra, 87Sr/86Sr, and 143Nd/144Nd whole rock data for three South <span class="hlt">Sister</span> rhyolites and two Newberry obsidians. The South <span class="hlt">Sister</span> rhyolites have homogeneous 87Sr/86Sr and 143Nd/144Nd ratios of ˜ 0.7036 and 0.51286 respectively. In contrast, the two Newberry obsidians have distinct 87Sr/86Sr (0.70366 vs. 0.70385) and 143Nd/144Nd (0.512879 vs. 0.512848) ratios. These values range from the same as, to slightly more radiogenic than, corresponding ratios measured in mafic lavas from the same region. The South <span class="hlt">Sister</span> rhyolites are in (230Th/238U) secular equilibrium, while the Newberry obsidians have small 230Th excesses of 4 and 7% at (230Th/232Th) of 1.20.

Methods Survey of trends in this work, and exploration of literature describing how large-scale structured and unstructured data sources are being used to support applications from clinical decision making and health policy, to drug design and pharmacovigilance, and further to systems biology and genetics. Results The survey highlights ongoing development of powerful new methods for turning that large-scale, and often complex, data into information that provides new insights into human health, in a range of different areas. Consideration of this body of work identifies several important paradigm shifts that are facilitated by <span class="hlt">Big</span> Data resources and methods: in clinical and translational research, from hypothesis-driven research to data-driven research, and in medicine, from evidence-based practice to practice-based evidence. Conclusions The increasing scale and availability of large quantities of health data require strategies for data management, data linkage, and data integration beyond the limits of many existing information systems, and substantial effort is underway to meet those needs.

Ctf7p/Eco1p is essential to establish <span class="hlt">sister</span>-chromatid pairing during S-phase and associates with DNA replication components. DNA helicases precede the DNA replication fork and thus will first encounter chromatin sites destined for cohesion. In this study, I provide the first evidence that a DNA helicase is required for proper <span class="hlt">sister</span>-chromatid cohesion. Characterizations of chl1 mutant cells reveal that CHL1 interacts genetically with both CTF7/ECO1 and CTF18/CHL12, two genes that function in <span class="hlt">sister</span>-chromatid cohesion. Consistent with genetic interactions, Chl1p physically associates with Ctf7p/Eco1p both in vivo and in vitro. Finally, a functional assay reveals that Chl1p is critical for <span class="hlt">sister</span>-chromatid cohesion. Within the budding yeast genome, Chl1p exhibits the highest degree of sequence similarity to human CHL1 isoforms and BACH1. Previous studies revealed that human CHLR1 exhibits DNA helicase-like activities and that BACH1 is a helicase-like protein that associates with the tumor suppressor BRCA1 to maintain genome integrity. Our findings document a novel role for Chl1p in <span class="hlt">sister</span>-chromatid cohesion and provide new insights into the possible mechanisms through which DNA helicases may contribute to cancer progression when mutated.

Methods As the vast stores of genomic information increase with next generation sequencing, the importance of deep phenotyping increases. The growth of genomic data and adoption of Electronic Health Records (EHR) in medicine provides a unique opportunity to integrate phenotype and genotype data into medical records. The method by which collections of clinical findings and other health related data are leveraged to form meaningful phenotypes is an active area of research. Longitudinal data stored in EHRs provide a wealth of information that can be used to construct phenotypes of patients. We focus on a practical problem around data integration for deep phenotype identification within EHR data. The use of <span class="hlt">big</span> data approaches are described that enable scalable markup of EHR events that can be used for semantic and temporal similarity analysis to support the identification of phenotype and genotype relationships. Conclusions Stead and colleagues’ 2005 concept of using light standards to increase the productivity of software systems by riding on the wave of hardware/processing power is described as a harbinger for designing future healthcare systems. The <span class="hlt">big</span> data solution, using flexible markup, provides a route to improved utilization of processing power for organizing patient records in genotype and phenotype research.

Senior decision makers have to learn to ask the right questions and embrace evidence-based decision making.

Following the late George Gamov's ideas in 1942 and more particularly in 1946 that the early universe was an appropriate site for the synthesis of the elements, they became deeply involved in the question of cosmic nucleosynthesis and particularly the synthesis of the light elements. In the course of this work they developed a general relativistic model of the expanding universe with physics folded in, which led in a progressive, logical sequence to our prediction of the existence of a present cosmic background radiation some seventeen years before the observation of such radiation was reported by Penzias and Wilson. In addition, they carried out with James W. Follin, Jr., a detailed study of the physics of what was then considered to be the very early universe, starting a few seconds after the <span class="hlt">big</span> bang, which still provides a methodology for studies of light element nucleosynthesis. Because of their involvement, they bring a personal perspective to the subject.

The field strikes for ~600 m between depths of 1550 and 1700 m and includes numerous, active, high-temperature (max 302°C) chimneys and even more dead, sulfide-rich spires. Chimney samples collected from <span class="hlt">Brothers</span> show distinct mineralogical zonation reflecting gradients in oxidation state, temperature, and pH from the inner walls in contact with hydrothermal fluids through to the outer walls in contact with seawater. Minerals deposited from hotter fluids (e.g., chalcopyrite) are located in the interior of the chimneys and are surrounded by an external zone of minerals deposited by cooler fluids (e.g., sulfates, sphalerite). Four chimneys types are identified at <span class="hlt">Brothers</span> volcano based on the relative proportions of chalcopyrite and sulfate layers, and the presence or absence of anhydrite. Two are Cu-rich, i.e., chalcopyrite-rich and chalcopyrite-bornite-rich chimneys, and two are Zn-rich, i.e., sphalerite-rich and sphalerite-chalcopyrite-rich. Barite and anhydrite are common to both Cu-rich chimney types whereas Zn-rich chimneys contain barite only. The main mineral phases in all the chimneys are anhydrite, barite, chalcopyrite, pyrite/marcasite, and sphalerite. Trace minerals include galena, covellite, tennantite, realgar, chalcocite, bornite, hematite, goethite, Pb-As sulfosalts, and Bi- or Au-tellurides. The vast majority of tellurides are <5 μm in size, although columnar crystals up to 80 μm long have been observed. The tellurides commonly form in bands, cluster in patches, or occur along internal grain boundaries within chalcopyrite. They also are found at the contact between chalcopyrite and pyrite grains. In sulfate layers adjacent to the chalcopyrite zones tellurides can occur as inclusions in anhydrite, barite or pyrite and/or occupy void space within the chimney.

Analysis of the effect of this mutation on pre-mRNA processing demonstrated markedly decreased levels of normal PGK1 mRNA.

H.</p> <p>2001-12-01</p> <p>The Three <span class="hlt">Sisters</span> region has recently come under increased scrutiny after the discovery by Satellite Radar Interferometry (InSAR) of a broad area of uplift centered approximately 5 km west of the South <span class="hlt">Sister</span> volcanic edifice (Wicks et al., 2001). The bulge, which at its center reaches a maximum of 10 cm, formed between 1998-2000. The exact cause for the uplift is unknown, but observations from other volcanoes and results from numerical modeling imply that the most likely cause is the movement of magma up to mid-crustal ( ~6.5 km depth) levels (Wicks et al., 2001). The area of uplift coincides with an area where spring chemistry shows anomalously high levels of chloride and carbon emissions (Ingebritsen et al., 1994). These features pre-date the bulge by at least a decade and can also be indicative of a magmatic source. It is unclear if the bulge and the geochemical anomalies are directly related, but both point to the presence of magma below the Three <span class="hlt">Sisters</span> area. Within the scope of a monitoring project that has recently been initiated to study the development of the bulge and any accompanying changes in the fluid/gas chemistry of springs in the Three <span class="hlt">Sisters</span> area, 10 gas samples were collected for noble gas analysis in July 2001. Two of these samples were taken from cold bubbling springs located close to the center of the bulge and the remaining 8 were obtained from well documented geothermal springs within the general area of Central Oregon. Helium isotope ratios (reported as Rc/Ra where Rc = air corrected 3He/4Hesample and Ra = 3He/4Heair) for these 8 samples range from 2.8 to 5.1 Ra which is in agreement with existing data reported in a study carried out by Unocal in the early 1980's of geothermal springs in this area. The data show a relationship with distance to the bulge/South <span class="hlt">Sister</span> volcano: all samples within a radius of ~30 km have helium isotope ratios in the range of 4.5 to 5.1 Ra, while samples that fall outside this radius have distinctly lower</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.ncbi.nlm.nih.gov/pubmed/24709435','PUBMED'); return false;" href="http://www.ncbi.nlm.nih.gov/pubmed/24709435"><span id="translatedtitle">Non-syndromic multiple hyperdontia in monozygotic twin <span class="hlt">sisters</span>: a report of two cases.</span></a></p> <p><a target="_blank" href="https://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed">PubMed</a></p> <p>Ratson, Tal; Peretz, Benjamin</p> <p>2014-01-01</p> <p>Supernumerary teeth are common in the general population, with a prevalence that varies between 0.1 percent to 3.8 percent.

An elder <span class="hlt">sister</span> had suffered from recurrent infections, small thrombocytopenic petechiae, purpura, and eczema for 7 years. The younger <span class="hlt">sister</span> had the same manifestations as the elder <span class="hlt">sister`s</span> for a 2-year period, and died of intracranial bleeding at age 2 years. All the laboratory data of the two patients were compatible with WAS, although they were females. Sialophorin analysis with the selective radioactive labeling method of this protein revealed that in the elder <span class="hlt">sister</span> a 115-KD band that should be specific for sialophorin was reduced in quantity, and instead an additional 135-KD fragment was present as a main band. Polymerase chain reaction (PCR) analysis of the sialophorin gene and single-strand conformation polymorphism (SSCP) analysis of the PCR product demonstrated that there were no detectable size-change nor electrophoretic mobility change in the DNA from both patients. The results indicated that their sialophorin gene structure might be normal. Studies on the mother-daughter transmission of X chromosome using a pERT84-MaeIII polymorphic marker mapped at Xp21 and HPRT gene polymorphism at Xq26 suggested that each <span class="hlt">sister</span> had inherited a different X chromosome from the mother. Two explanations are plausible for the occurrence of the WAS in our patients: the WAS in the patients is attributable to an autosomal gene mutation which may regulate the sialophorin gene expression through the WAS gene, or, alternatively, the condition in this family is an autosomal recessive disorder separated etiologically from the X-linked WAS. 17 refs., 6 figs., 1 tab.</p> </li> <li> <p><a target="_blank" onclick="trackOutboundLink('http://www.osti.gov/scitech/biblio/21308618','SCIGOV-STC'); return false;" href="http://www.osti.gov/scitech/biblio/21308618"><span id="translatedtitle">Turning <span class="hlt">big</span> bang into <span class="hlt">big</span> bounce.

During this period, which can last several hours, the continued attachment of <span class="hlt">sister</span> chromatids is thought to be achieved by inhibition of the protease separase. Separase is known to be inhibited by binding either securin or Maturation (M-Phase)-Promoting Factor, a heterodimer of CDK1/cyclin B1. However, the relative contribution of securin and CDK/cyclin B1 to <span class="hlt">sister</span> chromatid attachment during metII arrest has not been assessed. Although there are conditions in which either CDK1/cyclinB1 activity or securin can prevent <span class="hlt">sister</span> chromatid disjunction, principally by overexpression of non-degradable cyclin B1 or securin, we find here that separase activity is primarily regulated by securin and not CDK1/cyclin B1. Thus the CDK1 inhibitor roscovitine and an antibody we designed to block the interaction of CDK1/cyclin B1 with separase, both failed to induce <span class="hlt">sister</span> disjunction. In contrast, securin morpholino knockdown specifically induced loss of <span class="hlt">sister</span> attachment, that could be restored by securin cRNA rescue.
